The utility model realizes that the cab door has a stable installation structure.

[0004] In the transportation industry, some goods need to be transported in vans. To facilitate the loading and unloading of goods, a side door (push-pull, lift-up, etc.) is opened on the side of the van. The side door structure of traditional logistics vehicles is made of ordinary materials, consisting of inner / outer side door panels, reinforcement plates, etc., which leads to heavy weight, easy rust, high production cost, long production cycle, etc. Therefore, in order to solve the above problems, a new type of lightweight logistics vehicle side door assembly structure is necessary.

[0011] Furthermore, a side door middle sealing strip is fixedly arranged between the upper side door assembly and the lower side door assembly, and the upper side door assembly and the lower side door assembly are sealed and connected via the side door middle sealing strip.

[0012] Furthermore, the upper side door interior trim panel and the lower side door interior trim panel are both made of ABS material, are injection molded, and are fixedly connected to the upper frame assembly and the lower frame assembly respectively by screw connection.

[0013] The beneficial effects of the side door assembly structure of a novel lightweight logistics vehicle of the utility model are:

[0014] By setting up the upper frame assembly and the lower frame assembly, when in use, the main components of the upper frame assembly and the lower frame assembly structure are made of lightweight high-strength steel materials, which effectively reduces the overall weight of the side door assembly.
