Title:
AUTOMATIC SHEET CLOSING DEVICE IN CARGO BOX FOR VEHICLE
Document Type and Number:
Japanese Patent JP2020158116
Kind Code:
A
Abstract:
To provide an automatic sheet closing device in a cargo box for a vehicle capable of securely suppressing upward changing of a load current of a motor so that the load current remains to be around and less than a restriction current value, while avoiding an electrification cut-off event due to an inrush current, even when the restriction current value being a threshold value for cutting off electrification to the motor. is suppressed to a low level, so as to effectively prevent seizure of the motor and/or electrified circuit parts due to an excessive current.SOLUTION: An automatic controller U for controlling electrification cut-off means X capable of cutting off electrification to a motor M from a battery 10, comprises restriction means 40, which can operate to restrict electrification to the motor M. The restriction means 40 controls the electrification cut-off means X to intermittently cut off the electrification when the restriction means 40 is in an operation state, and to prolong an electrification cut-off time period tX as a load current approaches to a predetermined restriction current value I3.SELECTED DRAWING: Figure 1
