[0002] The battery pack is one of the core components of new energy vehicles. Since the car will vibrate and bump while driving, the vibration will cause damage to the battery pack, so the battery pack needs to be protected.
[0003] Chinese patent CN218677381U discloses a new energy vehicle battery shock absorption device, including a box for placing batteries, a cover plate is arranged at the opening position of the box, a placing plate is arranged at the bottom of the box, shock-absorbing springs are evenly arranged between the bottom of the box and the placing plate, a battery pack is arranged above the placing plate, a pressure plate is arranged above the battery pack, a compression spring is arranged between the pressure plate and the cover plate, and a shock-absorbing cotton pad is arranged between the side wall of the box and the battery pack; springs are placed at the bottom and top of the battery, and shock-absorbing cotton pads are also arranged on the side walls of the box, so that when the new energy vehicle travels on a bumpy road section, the springs and the shock-absorbing cotton pads can play a certain shock-absorbing role, thereby reducing the vibration of the battery, thereby protecting the battery, and the structure is simple, which well meets the use requirements.
[0004] The above patent only uses springs for shock absorption when in use. However, the spring only converts the impact force into elastic potential energy for temporary storage and releases it through continuous expansion and contraction movements, which increases the time of bumpy vibration and cannot achieve a good shock absorption effect. In addition, the above patent installs the battery in a box and covers the box with a cover, which greatly reduces the heat dissipation effect of the battery. When encountering high temperature weather, the battery is prone to overheating. Therefore, in view of the above situation, it is urgent to develop a new energy vehicle battery shock absorption device that absorbs and buffers vibrations and converts vibration force into frictional force to consume it, thereby reducing vibrations and improving the protection performance of the battery pack. The device has good heat dissipation performance for the battery pack, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the two impact force absorbing mechanisms are arranged symmetrically about the central axis of the installation box.

[0012] The beneficial effects of the utility model are as follows: when the new energy vehicle battery shock absorption device encounters bumps and vibrations, the installation box will produce up and down displacements, and the shock absorbing spring will absorb and buffer the vibrations. When the installation box moves up and down, it will drive the swing plate to swing, and the swing plate will drive the friction rod to move.

A plurality of shock absorbing springs 4 are installed on the base plate 1, and the tops of the plurality of shock absorbing springs 4 are connected to the bottom of the installation box 2. The battery pack 3 is installed in the installation box 2. The inner wall of the installation box 2 is installed with a rubber protective sleeve 201 for protecting the battery pack 3. Two impact force absorbing mechanisms 5 connected to the bottom of the installation box 2 are installed on the base plate 1. The two impact force absorbing mechanisms 5 are symmetrically arranged about the central axis of the installation box 2. The bottom of the installation box 2 is installed with an auxiliary heat dissipation mechanism 6 that is in contact with the battery pack 3. When in use, the shock absorbing spring 4 is used to buffer the vibration. When vibrating, the impact force is converted into friction force and consumed by the impact force absorbing mechanism 5, thereby reducing the damage of the vibration to the battery pack 3. In addition, when the temperature is high, the battery pack 3 can be cooled by absorbing heat through the auxiliary heat dissipation mechanism 6.

The friction plate 504 is fixed to the bottom plate 1. The friction plate 504 is provided with a through slot 505. A plurality of extension rods 507 inserted into the through slot 505 are fixed to the lower side of the swing plate 503. A friction rod 506 is fixed to the bottom of each extension rod 507.

The friction plate 504 and the friction rod 506 are both made of friction material, so that they have good wear resistance and a large friction coefficient. When encountering vibration, the installation box 2 will produce an up and down displacement. When the installation box 2 moves up and down, it will drive the swing plate 503 to swing, and the swing plate 503 swings to drive the friction rod 506 to move. When the friction rod 506 moves, it rubs against the friction plate 504 to convert the vibration force into friction force to consume it, thereby reducing the vibration.

When in use, the heat exchange plate 601 is cooled by the semiconductor refrigeration plate 602, the battery pack 3 is cooled by the heat exchange plate 601, and the heat at the hot end of the semiconductor refrigeration plate 602 is dissipated by the heat dissipation fin 603 to ensure the continuous cooling performance of the semiconductor refrigeration plate 602.
