Detailed Description

Other advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present specification, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings and preferred embodiments. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It should be understood that the preferred embodiments are illustrative of the utility model only and are not limiting upon the scope of the utility model.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

The embodiment provides a side wall assembly, as shown in fig. 3-6, which includes a side wall 1 and a lower body 2, when the side wall 1 and the lower body 2 are assembled, a cavity 3 is formed between the side wall 1 and the lower body 2, the cavity 3 is long and narrow and extends towards the X direction, and a reinforcement 4 is arranged inside the cavity 3 for improving the collision stability and safety of the whole vehicle.
