Problems solved by technology

[0002] Because a military off-road vehicle requires personnel to carry a large amount of equipment to quickly and conveniently get on the vehicle while the vehicle is moving, but the military off-road vehicle has a high threshold, and due to traffic restrictions, it is impossible to directly arrange the board on the vehicle body.
Existing side-opening doors cannot provide convenient boarding steps, and have great restrictions on the boarding space and boarding angle

Abstract

The invention provides a two-segment linkage automobile door with the upper portion and the lower portion in side by side connection. The automobile door comprises an upper automobile door, an upper automobile door hinge torsion rod assembly, a door lock assembly, a lower automobile door, a lower automobile door torsion rod assembly and an automobile door opening sealing bar assembly, wherein a linkage mechanism is installed between the upper automobile door and the lower automobile door and comprises an upper door supporting lug fixed to the upper automobile door, a lower door supporting lug fixed to the lower automobile door and a linkage rod which is hinged to the upper supporting lug and the lower supporting lug, a pedal assembly is arranged in the lower automobile door, one end of a limiting iron chain is fixed to the periphery of an automobile body, and the other end of the limiting iron chain is fixed to the pedal assembly. A pneumatic supporting rod is hinged to the middle of the linkage rod, and the lower end of the pneumatic supporting rod is fixed to the floor through a hinged base. Through the side by side connection automobile door with the upper portion and the lower portion turned, the requirement that one stair of pedal is needed when a person gets on an automobile can be met, the upper automobile opening space can be maximized, fighting passengers can carry equipment to get on or off the automobile fast in the running process of the automobile, and door opening and closing efficiency and safety can be improved through the pneumatic supporting linkage mechanism.

Description

technical field [0001] The invention relates to automobile components, in particular to a two-section linkage door of the upper and lower split type. Background technique [0002] A military off-road vehicle requires personnel to carry a large amount of equipment to quickly and conveniently get on the vehicle while the vehicle is moving, but the military off-road vehicle has a high threshold, and due to traffic restrictions, it is impossible to directly arrange the board on the vehicle body. Existing side-opening doors cannot provide convenient pedals for getting on the car, and have great restrictions on the getting on the car space and the angle of getting on the car. Therefore, a two-section linkage door that can be opened up and down is designed. The lower door is designed with the pedals required for getting on the car. At the same time, the opening method of opening up and down can not only maximize the door opening space, but also has no restrictions on the angle of g...
