Embodiment Construction

[0025] See attached picture.

[0026] Option 1: The battery system body (1) is composed of traditional structures such as battery modules, fixed module frames, boxes, and box covers. 3) Penetrate through the box wall, weld and fix the through-connection gap and do waterproof treatment. The upper beam (2) is physically connected to the longitudinal beam of the vehicle body, and the nuts are welded at appropriate positions, and the installation bolts penetrate through the beam (3), the chassis longitudinal beam, and are fastened on the upper beam (2). The penetrating beam (3) penetrates the lower box and is integrated with the inverted "several" bracket (4) at the bottom to form the supporting base of the lower module, while the penetrating beam is also the supporting base of the upper module. At the same time, the penetrating beam is also used as a structural part of the chassis, connecting the left and right longitudinal beams, and playing a structural role similar to the ori...

Abstract

The invention discloses a battery system structure capable of realizing integration of a battery system and an automobile chassis. The battery system structure capable of realizing integration of thebattery system and the automobile chassis comprises a battery pack body, an upper cross beam, a through cross beam, an adapter bracket, a bottom inverted omega-shaped bracket and an external electricappliance box which are mounted between chassis longitudinal beams. The battery pack body consists of an upper box body and a lower box body; the upper cross beam strides over the upper box body to befixed on longitudinal beams on the two sides by being attached to the longitudinal beam profiles; the bottom inverted omega-shaped bracket and the battery pack body are fixed to the through cross beam; the external electric appliance box is fixed to the lower box body; and the through cross beam with the battery pack body and the bottom inverted omega-shaped bracket are fixed to the longitudinalbeams or the adapter bracket. According to the battery system structure capable of realizing integration of the battery system and the automobile chassis, the structure is reasonable; the battery packframework is firm; and as the through cross beam running through the lower box body and the external electric appliance box are arranged, the integration of the chassis and the battery pack is realized.

Description

technical field [0001] The invention relates to the technical field of electric special vehicles, in particular to a structure applicable to the integrated design of the chassis of the vehicle and the power battery system. Background technique [0002] At present, the chassis layout of pure electric special vehicles basically adopts the physical connection of the battery system on both sides of the longitudinal beam of the vehicle body. The structural parts of the battery system are fixed on the chassis through some steel structures, and there is no shared structural skeleton design with the chassis, and there is no applicable The battery pack for the integrated solution of the chassis structure. Contents of the invention [0003] The purpose of the present invention is to provide a battery system structure in which the battery system and the chassis of the vehicle can be integrated. [0004] The present invention is achieved through the following technical solutions: ...
