Large plate type carriage with skirt edge

Abstract

The invention relates to a large plate type carriage with a skirt edge. The carriage comprises six wall plates, namely left and right lateral plates, front and rear end plates, a top plate and a bottom plate which are connected with each other. The six wall plates are sandwich plates made of a composite material. The left and right lateral plates and the front and rear end plates respectively and downwardly extend to the lower part of the bottom plate in an integral manner. The parts of the left and right lateral plates and the front and rear end plates at the lower part of the bottom plate are skirt edge parts. Compared with the prior art, the wall plates of the large plate type carriage with the skirt edge are the sandwich plates made of the composite material; the protective performances, such heat insulation and electronic shielding, are increased; furthermore, the carriage with the skirt edge is simple in shape; a prototype vehicle is subjected to the tests, such as running test and the like, and vehicle safety strong test; the carriage satisfies the requirements of a vehicular structure; the framework type carriage with the skirt edge can be completely replaced; besides higher protective performance, the carriage is also more simple and convenient to manufacture; the product consistency is strong; and the batch rapid customization production can be realized.

Description

Technical field [0001] The present invention is a special vehicle, in particular, a large-board car with skirts suitable for mass rapid customization production. Background technique [0002] In the prior art, there are mainly two types of production of various skirted compartments installed on the car chassis: one is to make the skirts and compartments separately first, and finally install the upper compartment as a whole on the subframe. This method is simple to make the carriage, and there is a boundary seam between the carriage and the skirt; the other is to use the inner frame to extend and paste the skin, this way the carriage and the skirt are seamlessly connected, the appearance is smooth, but the skeleton welding structure process is complicated , The production workload is large, the outer skin bonding requirements are high, and the product consistency is difficult to control. Summary of the invention [0003] In order to solve this problem, the present invention design...

Problems solved by technology

[0002] In the prior art, there are mainly two types of manufacture of various skirted carriages installed on the automobile chassis: one is to manufacture the skirts and carriages independently first, and finally install the upper carriage as a whole on the sub-frame. One method is simple to make the carriage, and there is a boundary seam between the carriage and the skirt; the other is to use the method of extending the inner skeleton and sticking the skin outside. This method seamlessly connects the carriage and the skirt, and the appearance is smooth, but the skeleton welding structure is complicated. , the production workload is heavy, the outer skin bonding requirements are high, and the product consistency is difficult to control
