Title:
CONTROL DEVICE AND CONTROL METHOD FOR HEIGHT-ADJUSTING DEVICE OF CURRENT COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2022/073345
Kind Code:
A1
Abstract:
A control device and control method for a height-adjusting device of a current collector, comprising a control device. The control device is used for controlling a first drive member (3) and a second drive member (4), so as to enable the contact time of the first drive member (3) and a crank (7) to be earlier than the contact time of a sliding plate (8) and a power supply rail (9) when the current collector is subjected to shoe raising; the control device is further used for controlling the first drive member (3) to retract after the second drive member (4) releases a four-bar mechanism (2). Due to the adoption of the technical solution, compared with the prior art, before the sliding plate (8) is in contact with the power supply rail (9), the crank (7) is propped by the first drive member (3), so that the sliding plate (8) is prevented from directly impacting on the power supply rail (9); after the second drive member (4) releases the four-bar mechanism (2), the first drive member (3) is controlled to retract, and the four-bar mechanism (2) slowly rotates in a shoe raising direction under the combined action of a first elastic member (1) and the first drive member (3), so that the sliding plate (8) slowly moves towards the power supply rail (9) and is in contact with the power supply rail (9), shoe raising is completed, the sliding plate (8) is prevented from violently impacting on the power supply rail (9), no noise is generated, and the product service life is prolonged.
