[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The following is an explanation of the preferred embodiments of the device of the utility model.

[0024] See also Figure 1-5 As shown, the protective device for the new energy vehicle battery includes a shell 1, an opening is provided on the top of the shell 1, and a switch door 2 is provided at the top opening of the shell 1, the four side panels on the upper surface of the shell 1 are obliquely connected to the four sides of the switch door 2, heat dissipation plates 3 are provided on both sides of the shell 1, and a protective plate 4 is provided on the internal vertical ring of the shell 1, and a shockproof buffer component 5 is provided on one side of the protective plate 4 corresponding to the inner side of the shell 1, and the side of the shockproof buffer component 5 away from the protective plate 4 is fixed to the inner side of the shell 1, and a clamping component 8 is provided inside the protective plate 4.

[0025] In another embodiment provided by the present invention, Figure 2 and 5 As shown, four compartment boxes 401 are distributed inside the protective plate 4, and placement grooves 402 are opened in the four compartment boxes 401. Filling pads 403 are provided at the bottom of the placement grooves 402, and batteries 6 are placed in the placement grooves 402. A cross-shaped placement cavity 7 is formed between the four compartment boxes 401, and a clamping assembly 8 is provided in the placement cavity 7 formed between two compartment boxes 401. The clamping assembly 8 includes a fixed block 801, a connecting rod 802, a spring clamping column 803, a turntable 804 and a clamping strip 805. The fixed block 801 is fixedly connected to the connecting rod 802, the top of the connecting rod 802 is fixedly connected to the spring clamping column 803, the top of the spring clamping column 803 is movably connected to the turntable 804, and the bottom of the turntable 804 is penetrated by a clamping strip 805.

[0026] Specifically, a filling pad 403 is provided at the bottom of the placement groove 402. The filling pad 403 is usually made of a soft and elastic material, such as rubber or silicone, which reduces the damage to the battery 6 during vibration or impact. When the battery 6 is placed in the placement groove 402, the cross-shaped placement cavity 7 formed between the four compartments 401 becomes the interval between the batteries 6. This cross-shaped placement cavity 7 not only increases the heat dissipation space between the batteries 6, preventing the batteries 6 from being damaged due to overheating; at the same time, it also provides an installation space for the clamping assembly 8. When the battery 6 needs to be fixed, first pull the turntable 804 upwards, and use the elastic force of the spring clamping column 803 to make the clamping bar 805 higher than the battery 6. Then, rotate the turntable 804 to change the direction of the clamping bar 805 by 90°, ensuring that the clamping bar 805 can be perpendicular to the upper surface of the battery 6. Then, release the turntable 804, and use the elastic restoring force of the spring clamping column 803 to make the clamping bar 805 close to the upper surface of the battery 6, thereby achieving the fastening of the battery 6.

[0027] The shockproof buffer assembly 5 includes a mounting bar 501, a butterfly spring column 502, a folding plate 503 and a stopper 504. Three groups of butterfly spring columns 502 are arranged on the same horizontal plane of the mounting bar 501. A folding plate 503 is arranged on the top of the butterfly spring column 502, and a stopper 504 is penetrated in the middle of the folding plate 503. Specifically, when the vehicle encounters bumps, shocks or vibrations during driving, the protective plate 4 transmits force to the folding plate 503 through the stopper 504, and the folding plate 503 is deformed immediately, and the butterfly spring column 502 thereon is compressed. The butterfly spring column 502, with its unique elastic deformation ability, converts the impact kinetic energy into the elastic potential energy of the spring, thereby achieving the effect of buffering and shock absorption, effectively absorbing and dispersing the impact force from the outside, and at the same time, due to the design of the folding plate 503, it bends with the deformation of the butterfly spring column 502, further dispersing the impact force, and ensuring the stability and reliability of the shockproof buffer assembly 5.

[0028] When in use, the battery 6 can be installed through the provided placement groove 402 first, and then the turntable 804 is pulled upwards, and the elastic force of the spring compression column 803 is used to make the compression strip 805 higher than the battery 6. Next, the turntable 804 is rotated to change the direction of the compression strip 805 by 90°, ensuring that the compression strip 805 can be perpendicular to the upper surface of the battery 6. Then, the turntable 804 is released, and the elastic restoring force of the spring compression column 803 is used to make the compression strip 805 close to the upper surface of the battery 6, thereby achieving the fastening of the battery 6. Finally, the switch door 2 is installed. When the battery 6 needs to be removed, it is only necessary to twist the turntable 804 to make the compression strip 805 parallel to the placement cavity 7. At this time, due to the action of the spring compression column 803, the compression strip 805 shrinks and resets, which facilitates the removal of the battery 6.
