Power battery pack supporting structure of portable battery-changing electric vehicle

Abstract

The invention provides a portable battery-changing electric vehicle power battery pack supporting structure, and the structure comprises a box body elastically installed on a vehicle body, and a battery pack body is inserted in the box body. The structure further comprises a cooling pipeline arranged on the box body, a protective cover arranged outside the battery pack body in a covering mode, an inserting assembly and a positioning assembly; the inserting assembly comprises an inserting part located on the protective cover and a socket part located on the vehicle body, and the inserting part and the socket part are matched in an inserting mode to form loading of the protective cover on the vehicle body; the positioning assembly comprises a positioning part located on the vehicle body and a positioning matching part located on the protective cover. According to the portable battery replacement electric vehicle power battery pack supporting structure, the damping effect on the battery pack body can be improved, the protective cover can be installed on a vehicle body in an inserting mode through the inserting assembly, the inserted protective cover is abutted and positioned through the positioning assembly, and therefore the protective cover can be conveniently installed and detached; and a good protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of power battery packs, in particular to a supporting structure for a portable electric vehicle power battery pack. Background technique [0002] In the prior art, the battery pack is usually installed on the vehicle body in a detachable manner, and the battery pack is fixed relative to the vehicle body in the installed state, so that the vibration force of the vehicle body is easily transmitted to the battery pack, thereby affecting the battery pack. Safety of use. [0003] In addition, a protective cover is often used to protect the battery pack, and the protective cover is usually placed outside the battery pack. In order to facilitate access to the battery pack, the traditional protective cover is usually installed in a detachable manner. For example, bolt fixing, although this installation method can achieve a fixing effect, it requires at least three or four sets of bolts during installation, and it ...

AI Technical Summary

Problems solved by technology

For example, bolt fixing, although this installation method can achieve a fixing effect, but at least three or four sets of bolts are required during installation, and it is not convenient to install and disassemble each time

For another example, there is also a snap-in structure to install the protective cover on the vehicle body, but this snap-in structure is generally a plastic part, which is prone to breakage when used for a long time in an environment with a low temperature in winter, and then affects the protective cover on the vehicle. The fixing effect on the body cannot guarantee the protection of the battery pack
