Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a new energy battery pack protection device. Background Art

[0002] In new energy electric vehicles, the battery pack is typically screwed into the center of the vehicle chassis, between the front and rear axles. This design not only lowers the vehicle's center of gravity, improving driving stability and handling, but also reduces direct impact on the battery pack during a collision, thereby enhancing safety. However, when the vehicle travels on poor road conditions, the jolting vibrations of the vehicle are transmitted to the battery pack, causing resonance. This resonance not only causes mechanical damage to the battery pack's internal components but also accelerates performance degradation, shortening its service life.

[0003] In order to address the above problems, it is necessary to develop a new energy battery pack protection device that can reduce the impact of vibration on the battery pack under various road conditions and ensure the long-term stability and reliability of the battery pack.

[0006] A new energy battery pack protection device is used to protect the battery pack of an electric vehicle, comprising two mounting frames, each mounting frame comprising a base plate, side plates, a support plate and a rubber belt. One side plate is fixedly provided on opposite sides of the base plate, and opposite sides of the support plate are connected to the free ends of the two side plates via a rubber belt. When the two mounting frames are fixedly buckled together facing each other, the battery pack is clamped between the two support plates of the two mounting frames.

[0007] Optionally, a mounting groove is provided at the free end of the side panel, a rotating shaft is rotatably connected to the side panel located in the mounting groove, the rubber belt is fixedly connected to the rotating shaft, and a locking mechanism is provided between the side panel and the rotating shaft, and the locking mechanism can selectively lock the rotating shaft to the side panel to allow or limit the rotating shaft to rotate relative to the side panel.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: See Figures 1 to 5 According to an embodiment of the present invention, a new energy battery pack protection device is provided for protecting a battery pack 1 of an electric vehicle, comprising two mounting frames 2. Each mounting frame 2 comprises a bottom plate 20, a side plate 21, a support plate 22, and a rubber belt 23. A side plate 21 is fixedly provided on opposite sides of the bottom plate 20. Opposite sides of the support plate 22 are connected to the free ends of the two side plates 21 by a rubber belt 23. When the two mounting frames 2 are fixedly buckled together facing each other, the battery pack 1 is clamped between the two support plates 22 of the two mounting frames 2.

[0024] In the new energy battery pack protection device using the above structure, the battery pack 1 is placed between two sets of mounting frames 2 and is tightened and fixed by four rubber belts 23. When the car is driving on a bumpy road, the rubber belts 23 can play a good buffering and shock-absorbing role, reducing damage to the battery pack 1 caused by vehicle vibration and extending the service life of the battery pack 1.

[0025] In this exemplary embodiment, a mounting slot 3 is provided at the free end of the side panel 21. A rotating shaft 4 is rotatably connected to the side panel 21 within the mounting slot 3. The rotating shaft 4 is rotatably connected to the side panel 21 via a bearing. The rubber band 23 is fixed to the rotating shaft 4 via glue or screws. A locking mechanism 5 is provided between the side panel 21 and the rotating shaft 4. The locking mechanism 5 can selectively lock the rotating shaft 4 to the side panel 21 to allow or restrict the rotation of the rotating shaft 4 relative to the side panel 21. With this arrangement, when installing the battery pack 1, the length of the rubber band 23 can be adjusted according to the height of the battery pack 1 to ensure that the rubber band 23 can tighten and secure the battery pack 1. Specifically, the length of the rubber band 23 can be adjusted by rotating the rotating shaft 4, and then the rotating shaft 4 can be fixed by the locking mechanism 5, thereby fixing the length of the rubber band 23.

[0026] In this exemplary embodiment, the locking mechanism 5 includes a latch 50, a connection base 51, and a socket 52. The connection base 51 is fixed to the side panel 21, and the latch 50 can be movably inserted through the connection base 51. The socket 52 is provided on the side wall of the rotating shaft 4 and is capable of plugging with the latch 50. To adjust the length of the rubber band 23, the latch 50 is removed from the socket 52, and the rotating shaft 4 is then rotated to adjust the length of the rubber band 23. After adjustment, the latch 50 is inserted into the socket 52 to restrict the rotation of the rotating shaft 4, thereby fixing the length of the rubber band 23.

[0027] In this exemplary embodiment, a hexagonal hole 40 is provided on the end surface of the rotating shaft 4. By using a hexagonal wrench in conjunction with the hexagonal hole 40, the rotating shaft 4 can be rotated more effortlessly.

[0028] In this exemplary embodiment, a block 210 is formed protruding from the free end of the side panel 21, and a slot 200 is provided on the bottom panel 20 for engaging with the block 210. The block 210 is secured within the slot 200 by a set screw 6. The engagement of the block 210 with the slot 200 and the use of the set screw 6 enhance the secure connection between the two mounting brackets 2 and facilitate assembly and disassembly.

[0029] In this exemplary embodiment, a plurality of heat dissipation holes 220 are evenly arranged on the support plate 22 to connect the upper and lower surfaces thereof. By providing the heat dissipation holes 220 on the support plate 22, the heat dissipation effect of the battery pack 1 can be improved to prevent the battery pack 1 from overheating.
