Abstract

The invention discloses an overall automobile lap joint structure of a weak hybrid power automobile lithium battery system. The weak hybrid power automobile lithium battery system comprises an air blower, an air guiding tube, a battery cover plate, a lithium battery module, a lithium battery wire harness assembly, a lithium battery exhausting tail tube, a mounting pressure plate, a lithium batterybond strap mounting support, a lithium battery tray and a lithium battery mounting support; the lithium battery mounting support is provided with a welding side; the lithium battery mounting supportis welded to a baggage compartment seat rear crossbeam through the welding side; a welding channel is formed in the lithium battery mounting support; the lithium battery mounting support is welded toa rear floor pane through the welding channel, and is protruded out of the rear floor plane; the lithium battery tray is assembled on the lithium battery mounting support through a double-screw bolt;and the lithium battery body is placed on the lithium battery tray, is positioned through a protrusion structure on the lithium battery tray, and is fixed on the lithium battery tray through bolts forthe mounting pressure plate. The problems of accumulated water pollution and poor NVH performance are solved, and the collision performance is good.

Description

technical field [0001] The invention belongs to a lithium battery system of a weak hybrid electric vehicle, and in particular relates to a vehicle lap joint structure of the lithium battery system of a weak hybrid electric vehicle. Background technique [0002] Such as Figure 11 As shown, the usual installation method of the existing weak hybrid electric vehicle lithium battery system is as follows: the lithium battery body 4 is fixed on the bottom of the trunk spare tire basin 19, and the spare tire is fixed on the lithium battery body through the lithium battery spare tire fixing bracket 13 4, this installation method is very likely to cause water accumulation in the spare tire pool, and it is difficult to repair and replace the battery. [0003] In addition, since the upper part of the lithium battery body 4 covers the storage box, it is difficult to dissipate heat. In order to solve the problem of heat dissipation, it is also necessary to lead out a long air induction ...
