A kind of vehicle and its door assembly

Abstract

The invention discloses a vehicle and a door assembly thereof. The door assembly comprises a door body (1), a folding leaf (3) and a folding leaf seat (4); one end of the folding leaf (3) is fixed to the door body (1) and while the other end of the folding hinge (3) is pivoted with the folding leaf seat (4); the folding leaf seat (4) is mounted to a vehicle body. The door assembly further comprises a limiting device that is used for locking or unlocking the folding leaf (3) and the folding leaf seat (4) from opposite rotating so as to lock or unlock the door body (1) from the opening state. According to the vehicle and the door assembly thereof, the limiting device special for locking or relocking the folding leaf and the folding leaf seat from opposite rotating is arranged, so that the opposite rotating of the folding leaf and the folding leaf seat is can be limited under the effect of the limiting device when the door body is opened, and as a result, the rotating of the door body is limited, and the door body is maintained in the opening state; therefore, that the door body is automatically closed during loading or unloading goods is avoided, and the safety and reliability of the door body are improved.

Problems solved by technology

During the actual loading and unloading process, when the wind is strong, or when the vehicle is on a route with a steep slope, the door often closes automatically, and staff have to be arranged to hold the door or use ropes, wires, etc. to fix the door. It affects the efficiency of loading and unloading, and the safety and reliability are low
