Description

[0002] With the advancement of science and technology and the improvement of environmental protection awareness, more and more automobile manufacturers are now starting to develop new energy vehicles, and the requirements for reliability, performance indicators, power density, etc. of new energy vehicles have been further improved. The battery pack is the power source of new energy vehicles. When new energy vehicles are often driving on bumpy roads, the power supply in the electronic equipment will be subjected to different degrees of vibration shock due to bumps and swaying, thereby reducing the service life of the battery and even affecting the normal power supply. Most of the existing ones are equipped with simple shock absorbing devices on the battery pack to protect the battery pack, but the current shock absorbing device has a single function and can only play a shock absorbing function. It cannot effectively use the vibration generated by the battery to supply power to the heat dissipation device set on the battery during the shock absorption process. The traditional battery heat dissipation device needs to rely on the power provided by the battery itself for heat dissipation, which reduces the endurance of new energy vehicles.

[0012] The extrusion assembly is arranged above the moving block and connected to the bottom of the support plate. The extrusion assembly is used to extrude the moving block so that the moving block touches the input end of the piezoelectric ceramic.

[0013] Furthermore, the shock absorbing mechanism includes a first sliding column vertically fixed to the bottom of the support plate, the bottom of the first sliding column is slidably connected to the second sliding groove, the second sliding groove is vertically opened at the top of the fixed block, and the first sliding column is provided with a second elastic member, one end of the second elastic member is fixed to the bottom of the support plate, and the other end of the second elastic member is fixed to the top of the fixed block.

The heat dissipation does not rely on the battery energy inside the car, thereby improving the battery life.

[0026] 2. When the present invention fixes the battery, the two threaded rods are quickly rotated by two handles to cooperate with the side walls of the placement frame so that the two first clamping plates move toward the center of the placement frame to clamp and fix the battery, which is very convenient.

[0027] 3. The second clamping plate of the present invention can further clamp the battery using elastic force, which not only has a good clamping effect, but also can convert the left and right vibrations generated by the battery into elastic potential energy through the third elastic member to avoid the battery from colliding with the inner wall of the placement frame. Moreover, when clamping, the rubber protrusion at the bottom of the card plate can be exposed to clamp the top of the battery, which can fix the battery well. BRIEF DESCRIPTION OF THE DRAWINGS
