DETAILED DESCRIPTION

[0013] Generally described, one or more aspects of the present disclosure relate to the configuration and management of one or more components to facilitate dual axis rotation. More specifically, one or more aspects of the present application relate to the configuration or management of a rotation mechanism to facilitate the dual axis rotation of a display device. Illustratively, the display device is mounted on rotation mechanism that facilitates a dual axis rotation utilizing a single actuator, dual rotation joints, and associated linkages. The rotation component further includes at least one additional floating joint that provides additional tension forces relative to a third axis. Still further, in accordance with further embodiments, a control component can be utilized to generate control signals relating to rotation of the single actuators, such as establishing control positions and duty cycles.

[0014] Traditional approaches to automating rotation mechanisms are limited to have individual actuators control rotation relative to a single axis. For example, a rotation mechanism facilitating rotation along a single axis would utilize a single actuator that controls rotation along a single axis. In a more complex example, a traditional rotation mechanism facilitating rotation along two axes would utilize multiple actuators for each rotational axis (e.g., two actuators to control two axis of rotation). Such traditional approaches can be inefficient or complex in terms of the number of parts forming the rotation mechanism. Additionally, such traditional rotation mechanisms require some form of synchronization signals or components to coordinate the operation of the plurality of actuators. Illustratively, the mounting structure 113 is fixed to the first rotational joint

[0015] In accordance with these embodiments and to address at least some of the deficiencies associated with traditional multi-component rotation mechanisms, one or more aspects of the present application include a rotation mechanism that includes single actuator that provides clockwise and counterclockwise rotation of the rotation mechanism defined about rotational axis. The rotation of the actuator can be defined in terms of control position relative to a specified angular position and the duty cycle defining an amount of time or actuator utilization to achieve the specified angular position. The rotation mechanism also includes a linkage structure that includes three rotation joints that result in a dual-axis pivot based on the single actuator

[0016] FIG. 1A is a perspective view of a rotational mechanism 101 including a linkage structure 104 for using in rotational mechanism in accordance with one or more aspects of the present application. The linkage structure 104 includes a first rotational joint 108 and second rotational joint 110 that cooperate in rotation based on rotation from a single actuator (not shown). Illustratively, the first rotational joint 108 and second rotational joint 110 are physically connected via one or more arms 109 or links that allow' for the translation of rotational forces applied to the first rotational joint 108 to be applied to the second rotational joint 110. As will be illustrated m greater detail below, responsive to rotational forces applied to the second rotational joint 110, the first rotational joint, the second rotational joint 110 will travel or rotate about a center axis 111 of the first rotational joint 108.

[0017] The linkage structure 104 further includes a mounting structure 113 that defines two or more anchor points 106 for mounting various components, such as a display component. As illustrated in FIG. lA, the mounting structure 113 can include a plurality of arms 115 for containing the anchor points 106. Illustratively, the arms 115 are equidistant from a center axis defined along the mounting structure 113. Additionally, the mounting structure 113 may be fixed or adhered to the second rotational joint such that mounting structure 113 will rotate in accordance with the rotation of the second rotational joint 110. As illustrated below, the mounted component (e.g., display device) will be rotate in accordance with the mounting structure 113. The geometry of the mounting structure 113 can vary' according to the dimensions of the component being mounted and the mounting requirements, such as the number of anchor points required based on dimensions, weight and forces being applied to the linkage structure 104 or mounted component.

[0018] The linkage structure 104 includes a third rotational joint 112 that does not directly rotate with the inputs from the single actuator but floats in a manner to provide forces in a third axis. Accordingly, the third rotational joint 112 may be referred to as a floating joint that travels along a linear axis in cooperation to control the rotation of the mounted components. Illustratively, the travel of the third rotational joint 1 12 or floating joint will be defined along a channel 117 defined within the mounting structure 113. The channel can include substantially horizontal surfaces and opposing diagonal surfaces that contact corresponding surfaces on the third rotational joint 112 in response to a tension force applied to the rotational joint, such as by a spring. In this regard, the floating joint aspect of the third rotational joint compensates for the different linear forces created by the cooperative rotation of the first and second rotational joints 108, 110. In some embodiments, the third rotational joint manages the movement of the mounting structure 113 (and mounted device), such as to keep the mounted device flush with other internal compartment portions of a vehicle, such a dashboard or console(s).

[0019] FIG. IB represents a different perspective view of a rotational mechanism 101 including a linkage structure relative to FIG. 1A. FIG. IB illustrates the linkage structure 104, including the first rotational joint 108 and second rotational joint 110 that cooperate in rotation. Additionally, FIG. IB illustrates a single actuator 114 that is connected to the first rotational joint 108 and provides rotational forces. FIG. IB also illustrates the mounting structure 113 and plurality of anchor points 106 connected via arms 115 of the mounting structure.

[0020] FIG. 2A is a perspective view of an illustrative embodiment of the present application including a combination of components 100 including a display device 102, rotational mechanism 101 and linkage structure 104. The display device corresponds illustrative to a video display device, such as a display device 102 utilized in a vehicle to display information to one or more occupants. The display device 102 is mounted to a linkage structure 104 via two mounting points 106. Additionally, the mounting structure 113 can include additional surfaces (one or more) that contact the mounted device (e.g., the display device.).

[0021] FIG. 2B is a different perspective view of a combination components 100 including a display device 102, rotational mechanism 101 and linkage structure 104 in accordance with one or more aspects of the present application. FIG. 2B illustrates the actuator 114.

[0022] FIGS. 3 and 4 illustrate different rotational states of a rotational mechanism in accordance with various illustrative embodiments. More specifically, FIG, 3 is a perspective view of a set of components including a display device, rotational mechanism and linkage structure illustrating a first rotational state responsive to a rotational force in accordance with one or more aspects of the present application. FIG. 4 is a perspective view of a set of components including a display device, rotational mechanism and linkage structure illustrating a second rotational state responsive to a rotational force in accordance with one or more aspects of the present application. Illustratively, the actuator 114 may be operated a duty cycle and direction of rotation that can incrementally cause a defined rotational force to be applied to the first rotational joint 108 and second rotational joint 110. The rotational force can be discretely defined such that the rotation of the mounting structure 113 can be defined in accordance with defined angular distances. Accordingly, FIGS. 3 and FIG. 4 may illustratively define the two endpoints of a range of rotation for the mounting structure 113. Accordingly, various additional rotational states may be included between the two endpoints in accordance with various increments. One skilled in the relevant art will appreciate, however, reference and illustration of the range of rotation is only illustrative in nature and should not he construed as limiting.

[0023] Turning now' to FIG. 3, a first rotational state of the display device 102 is illustrated based on rotation of the actuator 114 in clockwise rotation. The third rotational joint 112 (e.g., the floating joint) further translates along a third axis defined by the linear channel 117 of the mounting structure 113 to maintain continuity of the translation. FIG. 4 illustrates a second rotational state of the display device 102 based on rotation of the actuator 114 in a counterclockwise rotation. In combination, FIGS. 3 and 4 illustrate that the combination of the first and second rotational joints 108, 110 achieve a range of movement of the display device 102 based on a single actuator rotation. As illustrated in FIGS. 3 and 4, the position of the second rotational joint 110 rotates about a center axis 111 of the first rotational joint 108 from the full range of rotation attributable to the mounting structure 113.

[0024] Still further, the third rotational joints 112 ailow'S for movement of the display device in third axis direction defined linear channel 117. As described above, in embodiments in which the display device is integrated in a component of a vehicle, the third joint allows for movement of the display device 102 while maintaining the integration of the display device with the component, such as a portion of the dashboard. In embodiments in which the display device is not integrated into a component of the vehicle (e.g., a free- standing display), the third rotational joint facilitates additional movement of the display device along the third axis.

[0025] FIGS. 5A-5D illustrate various perspective views of a rotational joint 112 and linear channel 117 utilized in a linkage structure in accordance with various embodiments of the present application. With reference to FIG. 5A, a detailed representation of the third rotational joint 112 and supporting mechanisms is illustrated. As described above, the mounting structure 113 includes a linear channel 117 that includes a set of surfaces that define contact points for the third rotational joint 112. Specifically, the linear channel 117 includes two angular sections 502, 504 that will be complimentary to angular sections 506, 510 of the rotational joint 112. Similarly, the linear channel 117 illustratively includes two horizontal sections 507, 509 that will he complimentary to horizontal sections 511, 513 of the rotational joint 112. The interface with at least the angular or horizontal surfaces can also include bushings to control friction. [0026] The respective angular sections and horizontal sections create a flush mounting to allow the linkage structure 104 to absorb the forces presented to the rotational joint 112 via the tension mechanism 512, such as a spring. The resulting reaction is that the rotational joint 112 maintains contact with the linkage 104 as the two other rotational joints 108, 110 rotate. Although illustrated with angular sections, the rotational joint could also be implemented in different configurations.

[0027] With continued reference to FIG. 5 A, the linkage structure 104 can also include bushings 516 between the tension member and the mounting structure 113 to control friction.

[0028] FIG. 5B illustrates a cross section of the third rotational joint 112 and mounting structure 113. FIG. 5B illustrates the linear channel 117 of the mounting surface 113 that includes a set of surfaces that define contact points for the third rotational joint 112. Specifically, the linear channel 117 includes two angular sections 502, 504 that will be complimentary to angular sections 506, 510 of the third rotational joint 112. Similarly, the linear channel 117 illustratively includes two horizontal sections 507, 509 that will be complimentary to horizontal sections 511, 513 of the rotational joint 112. The interface with at least the angular or horizontal surfaces can also include bushings to control friction.

[0029] The linkage structure 104 can also include bushings 516 between the tension member and the mounting structure 113 to control friction. As illustrated in FIG. 5B, the third rotational joint 112 can further include a lock nut 514 for absorbing vibration forces, such as vibration forces created during utilization in vehicle operation.

[0030] FIG. 5C illustrates a fore aft section of the third rotational joint 112 and mounting structure 113. Similar to FIG. 5 A and FfG. B, FIG. 5C illustrates the connection between the third rotational joint 112 within the linear channel 117, including side surface 502 of the mounting structure 113, which abuts the side surface 506 of the third rotational joint. FIG 5C further illustrates bushings 516 between the tension member and the mounting structure 113 to control friction. The third rotational joint 112 can further include a lock nut 514 for absorbing vibration forces, such as vibration forces created during utilization in vehicle operation. [0031] FIG. 5D is a perspective view of an alternative embodiment of the third rotational joint 112 in which the side surfaces 506, 510 are not angular but substantially vertical. As also illustrated in FIG. 5D, in this embodiment, the third rotational joint 112 can include horizontal surfaces 511, 513 and the integrated tension member 512. In this embodiment, the third rotational joint 112 would still have the function to similar project movement along the linear channel 117.

[0032] FIG. 6 is a block diagram of a logical representative of various components of a control mechanism for operating a rotational mechanism including a linkage structure in accordance with aspects of the present application. The sensors/controllers 604 may receive user inputs for determining a desired rotation of a device, such as display device 102. Such examples can include manual inputs audio inputs, etc. The sensors/controllers 604 can detect characteristics of occupants for determining desired rotation. Such attributes can include physical attributes (e.g., height, weight, eye direction, etc.). Such attributes can also include identification of specific users, such as users preconfigured with user profiles. The sensors/controllers 604 can also include preconfigured settings for the rotational angles.

[0033] Control components 602 may correspond to any microprocessor-based controller, such a programmable logic controller (PLC) or other controller. The control components 602 can include logic that facilitates the selection of operational parameters for single actuator 114 in terms of rotational direction and duty cycle to achieve the desired rotational position. The control components 602 can also include the transmission of the operational parameters via a control signal or communication protocol.

[0034] Illustratively, the control component 602 can utilize a lookup table that can map information from identified sensors to operational parameters of the actuator 114, which results in the rotation of the rotation mechanism 101. In some embodiments, the lookup table can map individual sensor inputs/operational status to the determine operational parameters of the actuator (e.g., rotational angle and duty cycle).

[0035] FIG. 7 is a flow diagram illustrative of a routine implemented by the control components for the determination of operational parameters of the actuator for the application of rotational forces to the linkage structure 104 of the rotational mechanism. Routine 700 may be implemented for each individual component 602 to determine operational parameters for the actuator 114 and generate control signals corresponding to the determined operational parameters. At block 702, the control component 602 obtains a set of information sources, such as from a plurality of sensors 604, controllers, and the like.

[0036] At block 704, the control component 602 determines an appropriate lookup table. In some embodiments, one or more lookup tables utilized by the control component 602 can be specifically configured to individual vehicles. Alternatively, the lookup tables can be common to a set of vehicles, such as by vehicle type, geographic location, user type, and the like. For example, vehicles associated with the northeast region may be configured with a common table while vehicles associated with the south region may be configured with a different, common table. Still further, in other embodiments, a vehicle 100 may be configured with a set of tables that can be applied in accordance with geographic location, user, calendar time, and the like. For example, vehicles may be configured or select different lookup tables during winter months than in summer months or spring months. The lookup tables may be statically configured with the control component, which can be periodically updated. In other embodiments, the lookup tables can be more dynamic in which the frequency of update can facilitated via communication functionality associated with the vehicle. If multiple lookup tables are not provided or the control component is not otherwise configured to process selection criteria, a single lookup table can be automatically retrieved as part of the block 704.

[0037] At block 706, the control component 602 can optionally process the identified operational parameters to conduct error checking, threshold comparison, conflict resolutions, normalization, and the like.

[0038] At block 708 the control component 602 transmits information or control signals that causes the operation of the actuator in accordance with the selected and processed operational parameters, including the omission of the transmission of control signals. Illustratively, in some embodiments, the control component 602 can further monitor operation of the actuator 114 to monitor for anomalies or other inputs that may be indicative of various non-desired or error conditions. For example, the control component 602 may use vision systems to detect the presence of obstructions in the path of rotation that may be damaged by the display device (or other mounted device) or that may damage the display device or rotational mechanism 101 or other components. In another example, the control component 602 may monitor operational characteristics of the components, such as the actuator 114, that may be indicative of obstructions, failures, etc. Such operational characteristics can include power consumption, tuning of rotation, load or force measurements, and the like. Other examples or monitoring approaches may be included in accordance with aspects of the present application. In such scenarios, the control component 602 may terminate the selected rotation, generate notifications, create logs, and the like. Routine 700 returns to block 702 in embodiments for continuous monitoring or can wait for institution of the routine 200.
