New energy automobile battery pack protection device

Abstract

The invention discloses a new energy automobile battery pack protection device which comprises a box body, a first supporting plate is fixedly connected to the outer surface of the box body, a first through hole is formed in the outer surface of the first supporting plate, a first polished rod is inserted into the first through hole, and a first sliding block is slidably connected to the outer surface of the first polished rod; and one end of the first sliding block is fixedly connected with a box body. According to the new energy automobile battery pack protection device, through cooperativearrangement of a first polished rod, a first sliding block, a first spring, a screw rod, a first rotating disc and a second rotating disc, the screw rod is driven to rotate by rotating to the first rotating disc and the second rotating disc in the using process, so that the first sliding block moves on the first polished rod, and the spring is compressed; therefore, the purpose of changing the size of the box body is achieved, the purpose of using batteries with different sizes is achieved, and through the arrangement of the filter screen, the new energy automobile battery pack protection device has the purpose of preventing sundries from entering the battery pack through the heat dissipation device.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a protective device for battery packs of new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] The most important part of new energy vehicles is the battery pack, and the existing new energy vehicles generally do not have a special protection device for the battery. Some vehicle protection devices have a relatively fixed shape and cannot be applied to different battery sizes. There is no corresponding heat dissipation device to solve the heat generated by the battery due to driving, which affects the service life of the batter...
