Title:
TRUCK BED COVER OPENING-AND-CLOSING LIFTING/LOWERING DETENT MECHANISM
Document Type and Number:
WIPO Patent Application WO/2016/090711
Kind Code:
A1
Abstract:
Provided is a truck bed cover opening-and-closing lifting/lowering detent mechanism, used for a truck (10); the truck (10) is provided with a truck bed (12) and an n-shaped swing arm (14); the two ends of the swing arm (14) each form a free end (142); below the truck bed (12), a pivot (15) is fixedly provided at the two free ends (142), and the lifting/lowering detent mechanism comprises a cover net raising device (30) and a cover net press-closing device (40). The cover net raising device (30) contains a first resilient member (33); one end of the first resilient member (33) is attached to the bottom side of the truck bed (12), and the other end is attached to a boom (140); a first distance is formed between the position where the boom (140) connects to the cover net raising device (30) and the pivot (15); the cover net press-closing device (40) contains a second resilient member (43); one end of the second resilient member (43) is attached to the bottom side of the truck bed (12), and a swing member (45) is connected to the second resilient member (43); a second distance is formed between the position where the swing member (45) is connected to the second resilient member (43) and the center of the pivot (15). The lifting/lowering detent mechanism stably and effectively causes the cover to open or to cover the truck bed, while also reducing the wear and tear on a truck lifting/lowering retractor mechanism.
