Description

Technical Field

[0001] The utility model relates to a pickup truck, in particular to a special hinge structure for a pickup truck cargo box door. Background Art

[0002] With the opening of the pickup truck market, the number of people facing pickup trucks has increased, and pickup truck customers have gradually increased their demands for the convenience of cargo box doors and multi-scenario use. The cargo box doors of existing pickup trucks generally use central or side hinges, and it takes two people to take and put the cargo box doors, which is time-consuming and labor-intensive, and extremely inconvenient to operate. In addition, the hinges and slow-down of the cargo box doors and cargo boxes of existing pickup trucks are installed separately, which makes installation difficult, and some slow-down structures (such as strut-type slow-down) have external leakage, which affects the appearance; some slow-down structures such as torsion bars can be installed internally, but they are difficult to install. Therefore, how to design an articulated structure that is convenient for disassembling the cargo box door and can take into account the slow-down and aesthetics of the cargo box door is crucial to improving the quality of pickup trucks.
