Title:
POWER SUPPLY MECHANISM OF LONG-TRAVEL SEAT
Document Type and Number:
WIPO Patent Application WO/2020/140660
Kind Code:
A1
Abstract:
Disclosed is a power supply mechanism of a long-travel seat, the mechanism comprising: a wiring harness storage box (11), the wiring harness storage box (11) being provided with at least one storage space and an opening (10); a drag chain (12) bent and accommodated in the storage space, with a first end (121) being relatively fixed to the wiring harness storage box (11), and a second end (122) passing out of the opening (10) and being slidingly arranged inside a slideway of a lower slide rail (21) of the seat; and a wiring harness arranged in the drag chain (12) in a penetrating manner, with a first end passing out of a first end of a wiring harness passage and the opening (10) and being connected to a power supply body, and a second end passing out of a second end of the wiring harness passage and being connected to an upper slide rail (22) of the seat. By using a drag chain to accommodate a wiring harness inside a wiring harness storage box and inside a slideway of a lower slide rail of a seat, the wiring harness can share a slideway with an upper slide rail and moves along with the sliding of the upper slide rail; and the drag chain shuttles back and forth in the wiring harness storage box and the lower slide rail with the movement of the wiring harness, thereby satisfying a power supply requirement of a long-travel seat.
