[0003] The prior art document, "A Protective Device for a Battery Pack of a New Energy Vehicle," patent number (CN221766938U), significantly enhances the structural strength of the battery pack by installing frame-shaped reinforcing rods on both sides of the battery pack and mounting telescopic components on these rods. This design effectively prevents the battery pack from deforming under external impact or compression, thereby protecting the internal battery pack.

[0004] However, battery pack protection devices are often designed as a whole structure and cannot protect the battery individually, resulting in low battery protection and inconvenience to users, which no longer meets their needs. Utility Model Content

[0005] The purpose of this utility model is to provide a battery pack protection device for new energy vehicles, in order to solve the problem that the battery pack protection devices mentioned in the background art are often designed as an integral structure and cannot protect the battery separately, resulting in low battery protection, inconvenience to users, and failure to meet user needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a new energy vehicle battery pack, comprising an external protective frame, a battery groove on the front surface of the external protective frame, four elastic clamping posts surrounding the inner wall of the battery groove, cavities inside the elastic clamping posts, an elastic steel ring at the center of the elastic clamping posts, a cavity inside the elastic steel ring, a force-bearing rod at the center of the elastic steel ring, movable grooves on both sides of the elastic steel ring, support columns fixedly installed at the top and bottom of the elastic steel ring, and damping springs fixedly installed at the top and bottom of the elastic steel ring.

[0007] Furthermore, the number of battery slots is several, and each pair of battery slots is designed to be equidistant from each other.

[0008] Furthermore, both sides of the force-bearing rod pass through the movable groove and are fixedly connected to the inner wall of the battery slot, and the force-bearing rod is movably connected to the movable groove.

[0009] Furthermore, the opposite sides of the two support columns are fixedly connected to the inner wall of the battery compartment, and the support columns are made of rubber.

[0010] Furthermore, the opposite sides of both damping springs are fixedly connected to the force-bearing rod.

[0011] Furthermore, a protective strip is provided around the outer surface of the external protective frame, and the protective strip is fixedly connected to the external protective frame.

[0012] Furthermore, the depth of the battery slot is greater than the length of the battery.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This new energy vehicle battery pack protection device, by setting up elastic clamps, elastic steel rings, force-bearing rods and damping springs, can isolate the batteries during use and provide individual protection for each battery, thereby improving the protection performance of the batteries, bringing convenience to users, improving the practicality of the device, and meeting the user's needs.

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a protective device for a new energy vehicle battery pack, including an external protective frame 1, which is used to set up corresponding components. A battery slot 2 is opened on the front surface of the external protective frame 1, which is used to place the battery. Four elastic clamping posts 3 are arranged around the inner wall of the battery slot 2, which are used to clamp the battery and prevent it from loosening. The elastic clamping posts 3 have cavities inside, and an elastic steel ring 4 is set in the middle of the elastic clamping posts 3. The elastic steel ring 4 is used to set up corresponding components. The elastic steel ring 4 has cavities inside, and a force-bearing rod 5 is set in the middle of the elastic steel ring 4, which can bear force. Movable slots 6 are opened on both sides of the elastic steel ring 4, which facilitates the movement of the elastic steel ring 4. Supporting columns 7 are fixedly set at the top and bottom of the elastic steel ring 4, which can provide support. Damping springs 8 are fixedly set at the top and bottom of the elastic steel ring 4, which can absorb energy and buffer.

[0022] Furthermore, the number of battery slots 2 is several, and each pair of battery slots 2 is designed to be equidistant from each other. The battery slots 2 are used to hold batteries.

[0023] Furthermore, both sides of the force-bearing rod 5 pass through the movable groove 6 and are fixedly connected to the inner wall of the battery groove 2. The force-bearing rod 5 and the movable groove 6 are movably connected, and the force-bearing rod 5 plays the role of bearing force.

[0024] Furthermore, the opposite sides of the two support columns 7 are fixedly connected to the inner wall of the battery compartment 2. The support columns 7 are made of rubber and serve as supports.

[0025] Furthermore, the two damping springs 8 are fixedly connected to the force-bearing rod 5 on opposite sides, with the damping springs 8 serving as energy-absorbing buffers.

[0026] Furthermore, a protective strip 9 is provided around the outer surface of the outer protective frame 1, and the protective strip 9 is fixedly connected to the outer protective frame 1. The protective strip 9 serves to protect the outer surface.

[0027] Furthermore, the depth of the battery slot 2 is greater than the length of the battery, and this design ensures complete protection for the battery.

[0028] Working principle: When using this device, the user inserts each battery into the corresponding battery slot 2 and uses the elastic clamping post 3 to clamp the battery. When it is hit, the impact force acting on the outer protective frame 1 will cause the support post 7 to deform. The deformation of the support post 7 will cause the elastic steel ring 4 to move. The movement of the elastic steel ring 4 will cause the damping spring 8 to deform, thereby absorbing and buffering the impact force. Through the setting of the force rod 5, it can withstand the impact force and reduce the damage to the battery caused by the impact force.

[0029] Based on the above work process, we can conclude that:

[0030] This new energy vehicle battery pack protection device, by setting up elastic clamping posts 3, elastic steel rings 4, force-bearing rods 5 and damping springs 8, enables the device to isolate the batteries during use and provide individual protection for each battery, thereby improving the protection performance of the batteries, bringing convenience to users, improving the practicality of the device, and meeting the user's needs.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
