[0002] As new energy devices become more widespread, battery pack safety is becoming increasingly critical. Traditional cover plates have limited buffering performance and can easily damage the battery structure or even cause safety hazards during collisions.

[0003] Meanwhile, a battery pack cover and a battery pack are disclosed (announcement number CN219040650U). The battery pack cover includes: a cover body, a first fitting area formed on a first side of the cover body, and a second fitting area formed on a second side of the cover body; a label, the label being located on the first side of the cover body and fitting to the first fitting area; and a buffer, the buffer being located on the second side of the cover body and fitting to the second fitting area.

[0004] The aforementioned battery pack cover and battery pack can only be improved to increase the efficiency of the battery pack cover production line and reduce labor costs. However, they cannot provide collision buffering for the battery pack inside the cover. As a result, when the battery pack is subjected to impact and compression, the battery core is prone to thermal runaway and fire due to the lack of effective buffering. Other internal components may be short-circuited and catch fire or even explode due to compression and impact during use.

[0005] Therefore, a collision-resistant battery pack cover with a buffer pad is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following describes an embodiment of this utility model based on its overall structure.

[0028] like Figures 1 to 4 As shown, this utility model provides a collision-resistant battery pack cover with a buffer pad, including a silicone buffer pad 5 fixedly installed inside the upper cover 1 for buffering, an aluminum plate 2 fixedly installed on the outer side of the upper cover 1, a rigid material layer 3 fixedly installed on the upper end surface of the aluminum plate 2, a polyethylene honeycomb foam plastic layer 7 fixedly installed on the lower end surface of the silicone buffer pad 5 for buffering and protection, and a battery bracket 6 fixedly installed on the lower end surface of the polyethylene honeycomb foam plastic layer 7 for insulation.

[0029] A battery pack 10 is fixedly mounted on the lower end face of the battery bracket 6. Magnetic grooves 8 are opened in the middle of the left and right sides of the lower end face of the upper cover plate 1. Magnetic blocks 11 are fixedly mounted inside the magnetic grooves 8 to play a fixing role. A lower cover plate 9 is fixedly mounted on the lower end face of the magnetic blocks 11, and the lower cover plate 9 is in contact with the upper cover plate 1.

[0030] The lower cover plate 9 is equipped with a silicone cushioning pad 14 for cushioning, and a polyethylene honeycomb foam layer 15 is fixed on the upper surface of the silicone cushioning pad 14.

[0031] The lower outer side of the upper cover plate 1 is fixed with silicone sealant 4 for sealing and fixing, and the lower inner side of the silicone sealant 4 is fixed with the lower cover plate 9.

[0032] A polyethylene honeycomb foam layer 7 is fixedly provided on the upper end face of the second polyethylene honeycomb foam layer 15 to serve as a buffer, and the first polyethylene honeycomb foam layer 7 is fixed to the battery pack 10.

[0033] A copper plate 12 is fixedly provided on the lower end face of the lower cover plate 9 to serve as a heat dissipation device, and a rigid material layer 13 is fixedly provided on the lower end face of the copper plate 12.

[0034] The working principle and process of a collision-resistant battery pack cover with a cushioning pad:

[0035] The design of this anti-collision battery pack cover with cushioning pads is mainly to effectively protect the battery pack 10. Its working principle is based on the characteristics and cooperation of each component. The function of the silicone cushioning pads: The silicone cushioning pad 5 inside the upper cover 1 and the silicone cushioning pad 14 inside the lower cover 9 have good elasticity and cushioning performance. When the battery pack 10 is subjected to external collision or impact, the silicone cushioning pads can absorb and disperse part of the impact force, reducing the force directly transmitted to the battery pack 10, thereby reducing the risk of damage to the battery pack 10 due to collision. The function of the polyethylene honeycomb foam layers: The polyethylene honeycomb foam layers 7 and 15 also have a cushioning effect. Their honeycomb structure makes them resistant to pressure. This material can deform under force, further absorbing and dispersing the impact. It is also lightweight, ensuring a cushioning effect without adding excessive burden to the battery pack 10. Magnetic blocks 11 are installed in the magnetic grooves 8 inside the lower left and right sides of the upper cover 1. These magnetic blocks 11 are connected to the lower cover 9, allowing the upper cover 1 and lower cover 9 to fit tightly together. This magnetic connection method not only facilitates installation and disassembly but also ensures the relative position of the upper cover 1 and lower cover 9 remains stable during normal use, preventing loosening due to shaking or vibration. Silicone adhesive 4 at the lower outer side of the upper cover 1 fixes the upper cover 1 and lower cover 9 together. Silicone adhesive 4 has good adhesion and sealing properties, further enhancing the connection between the upper cover 1 and lower cover 9. The aluminum plate 2 is located on the outer side of the upper cover plate 1, and the copper plate 12 is located on the lower end face of the lower cover plate 9. Both the aluminum plate 2 and the copper plate 12 have good thermal conductivity, which can conduct away the heat generated by the battery pack 10 during operation, which helps to dissipate heat from the battery pack 10 and ensure that the battery pack 10 operates in a suitable temperature environment. The first rigid material layer 3 is located on the upper end face of the aluminum plate 2, and the second rigid material layer 13 is located on the lower end face of the copper plate 12. These two rigid material layers can provide additional physical protection for the battery pack 10, preventing external sharp objects from directly impacting the battery pack 10, thus protecting the battery pack 10. A silicone cushioning pad 5 is fixedly installed inside the upper cover plate 1. An aluminum plate 2 is fixedly installed on the outside of the upper cover plate 1. A rigid material layer 3 is then fixedly installed on the upper surface of the aluminum plate 2. A polyethylene honeycomb foam layer 7 is fixedly installed on the lower surface of the silicone cushioning pad 5. A battery bracket 6 is then fixedly installed on the lower surface of the polyethylene honeycomb foam layer 7. A battery pack 10 is fixedly installed on the lower surface of the battery bracket 6. Magnetic grooves 8 are formed in the middle of the left and right sides of the lower surface of the upper cover plate 1, and magnetic blocks 11 are fixedly installed inside the magnetic grooves 8. A silicone cushioning pad 14 is fixedly installed inside the lower cover plate 9. A polyethylene honeycomb foam layer 15 is fixedly installed on the upper surface of the silicone cushioning pad 14. The lower cover plate 9 is then attached to the upper cover plate 1 using the magnetic blocks 11.Fix the lower end face of the magnetic block 11 to the lower cover plate 9. Apply silicone sealant 4 to the lower outer side of the upper cover plate 1, and fix the lower inner side of the silicone sealant 4 to the lower cover plate 9. This completes the assembly of the entire battery pack 10 cover plate. When the battery pack 10 is working normally, the aluminum plate 2 and copper plate 12 conduct away the heat generated by the battery pack 10, ensuring heat dissipation. If the battery pack 10 is subjected to external collision or impact, the silicone buffer pad 1 5, silicone buffer pad 2 14, polyethylene honeycomb foam layer 1 7, and polyethylene honeycomb foam layer 2 15 will absorb and disperse the impact force, protecting the battery pack 10. Without damage, the magnetic block 11 and silicone sealant 4 ensure a tight connection and stability between the upper cover 1 and the lower cover 9, preventing separation during use and ensuring the normal operation of the battery pack 10. If maintenance or component replacement is required, the silicone sealant 4 can be removed first. By overcoming the magnetic force of the magnetic block 11, the lower cover 9 can be separated from the upper cover 1, allowing the battery pack 10 cover to be opened. Internal components such as the battery pack 10 and battery bracket 6 can then be inspected, maintained, or replaced. After maintenance, the battery pack 10 can be reassembled according to the assembly procedure.
