Description

Technical Field

[0001] This utility model relates to the field of gaskets, specifically a high flame-retardant shock-absorbing gasket for electric vehicle batteries. Background Technology

[0002] With the rapid development of the electric vehicle industry, the safety and stability of batteries, as core components, have become a major concern. During electric vehicle operation, batteries are subjected to various external forces such as road bumps and vibrations. Prolonged vibration can not only loosen the internal structure and damage components, but also affect the battery's lifespan and performance. Simultaneously, batteries may generate heat during charging and discharging. If the gaskets do not have good flame-retardant properties, short circuits or other accidents can easily lead to safety incidents. Traditional electric vehicle battery gaskets mostly focus on a single shock-absorbing function, using ordinary rubber or foam materials. Their flame-retardant effect is poor, and they are prone to elastic fatigue under long-term vibration, leading to a decline in shock-absorbing performance and failing to meet the high battery protection requirements of modern electric vehicles. Utility Model Content

[0003] The purpose of this invention is to provide a high flame-retardant shock-absorbing pad for electric vehicle batteries, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high flame-retardant shock-absorbing pad for electric vehicle batteries, comprising a battery bracket and shock-absorbing pads fixedly installed at the four corners of the bottom of the battery bracket. Each of the four shock-absorbing pads includes a pad body, with reinforcing side frames embedded on the surface of the pad body. A damping pad is fixedly installed on the top of the pad body. The pad body includes an outer pad, with a top pad fixedly installed on the top of the outer pad. A middle pad is fixedly installed at the center of the bottom of the outer pad. A large V-shaped groove is formed between the outer pad and the middle pad. An outer rubber foot pad is fixedly connected to the bottom of the outer pad, and the bottom of the middle pad is fixedly connected to... The device includes a middle rubber foot pad, an outer rubber foot pad with a horizontal V-shaped groove at the bottom, and a middle rubber foot pad with a vertical V-shaped groove at the bottom. The outer pad, middle pad, and top pad are an integral structure, all made of PE foam. The bottom of the damping pad is fixedly connected to the top of the top pad, and the reinforcing frame is embedded in the outer pad and top pad. The shock-absorbing pad is made of PE foam, which has flame-retardant, sound-insulating, and shock-absorbing properties. It can effectively play a flame-retardant role and effectively attenuate the transmission of vibration. The damping pad converts vibration energy into heat energy through its own damping characteristics, thus avoiding the occurrence of resonance.

[0005] Preferably, the periphery of both the outer pad and the middle pad is designed as a downward sloping surface.

[0006] Preferably, an adhesive sheet is fixedly disposed on the top of the damping pad, and the adhesive sheet is bonded to the battery bracket. The damping pad improves the stability of the adhesive sheet by increasing the frictional resistance.

[0007] Preferably, the reinforcing frame includes a bottom frame and a top frame. Support rods are fixedly connected to the four corners of the top of the bottom frame. The top ends of the four support rods are fixedly connected to the four corners of the bottom of the top frame. Corner blocks are fixedly connected to the four corners of the top of the top frame. The four support rods are all inclined.

[0008] Preferably, the bottom frame is embedded on the outer side of the bottom of the outer pad, the top frame is embedded on the outer side of the top of the outer pad, the four support rods are embedded on the four sides of the surface of the outer pad, and the four corner blocks are embedded on the four corners of the top pad.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by strengthening the side frame, the overall structural strength of the gasket body is effectively improved, the gasket is prevented from deforming under long-term stress or vibration, and the connection between the top pad and the damping pad is prevented from being damaged due to stress concentration.

[0010] The downward sloping design around the outer and middle pads can guide stress dispersion when the pads are subjected to lateral forces, reduce the risk of damage caused by local compression, improve the overall shock absorption effect, and enable the pads to adapt to different degrees of vibration and impact, thereby providing more comprehensive and reliable protection for electric vehicle batteries.

[0011] The outer, middle, and top pads of the shock-absorbing pads are made of PE foam. PE foam has the characteristics of flame retardancy, sound insulation, and shock absorption, and can effectively play a role in flame retardancy and effective shock absorption. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-6 This utility model provides a high flame-retardant shock-absorbing pad for electric vehicle batteries, including a battery bracket 18 and shock-absorbing pads 17 fixedly installed at the four corners of the bottom of the battery bracket 18. Each of the four shock-absorbing pads 17 includes a pad body 1, with a reinforcing frame 2 embedded on the surface of the pad body 1. A damping pad 3 is fixedly installed on the top of the pad body 1. The pad body 1 includes an outer pad 14, with a top pad 16 fixedly installed on the top of the outer pad 14. A middle pad 15 is fixedly installed at the center of the bottom of the outer pad 14. A large V-shaped groove 13 is formed between the outer pad 14 and the middle pad 15. An outer rubber foot pad 5 is fixedly connected to the bottom of the outer pad 14, and a middle rubber foot pad 10 is fixedly connected to the bottom of the middle pad 15. A transverse V-shaped groove 11 is formed at the bottom of the outer rubber foot pad 5. The bottom of pad 10 has a longitudinal V-shaped groove 12. The outer pad 14, middle pad 15 and top pad 16 are an integral structure. The outer pad 14, middle pad 15 and top pad 16 are all made of PE foam. The bottom of the damping pad 3 is fixedly connected to the top of the top pad 16. The reinforcing frame 2 is embedded in the outer pad 14 and top pad 16. The battery bracket 18 contacts the mounting surface through the bottom shock-absorbing pad 17. When the equipment vibrates during operation, the shock-absorbing pad 17 absorbs the vibration energy from different directions. The reinforcing frame 2 strengthens the structural strength of the shock-absorbing pad 17. The outer pad 14, middle pad 15 and top pad 16 of the shock-absorbing pad 17 are made of PE foam. PE foam has the characteristics of flame retardancy, sound insulation and shock absorption. It can effectively play a flame retardant role and can effectively attenuate the transmission of vibration.

[0021] The periphery of both the outer pad 14 and the middle pad 15 is designed as a downward sloping surface.

[0022] An adhesive piece 4 is fixedly installed on the top of the damping pad 3, and the adhesive piece 4 is bonded to the battery bracket 18; the shock-absorbing pad 17 is bonded to the battery bracket 18 through the adhesive piece 4.

[0023] The reinforcing frame 2 includes a bottom frame 6 and a top frame 8. Support rods 7 are fixedly connected to the four corners of the top of the bottom frame 6. The top ends of the four support rods 7 are fixedly connected to the four corners of the bottom of the top frame 8. Corner blocks 9 are fixedly connected to the four corners of the top of the top frame 8. The four support rods 7 are all inclined. The bottom frame 6 is embedded on the outer side of the bottom of the outer pad 14, the top frame 8 is embedded on the outer side of the top of the outer pad 14, the four support rods 7 are embedded on the four sides of the surface of the outer pad 14, and the four corner blocks 9 are embedded on the four corners of the top pad 16. The reinforcing frame 2 forms a three-dimensional support structure through the bottom frame 6, the top frame 8, and the inclined support rods 7. The bottom frame 6 is on the outer pad 14. 4. The bottom outer side provides basic support, and the top frame 8 enhances edge stability on the top outer side of the outer pad 14. The four inclined support rods 7 extend from the corners of the bottom frame 6 to the corners of the top frame 8, effectively dispersing the lateral force on the pad body 1 during vibration, preventing the outer pad 14 and the top pad 16 from structural displacement due to excessive deformation. At the same time, the corner blocks 9 embedded in the four corners of the top pad 16 further strengthen the structural strength of the connection between the top pad 16 and the damping pad 3, avoiding local tearing of the damping pad 3 under long-term pressure vibration, ensuring the coordinated action of the reinforcing frame 2 and the pad body 1, and improving the overall structural stability and service life of the shock-absorbing pad 17.

[0024] In this embodiment, the electric vehicle battery is installed on the battery bracket 18. The battery bracket 18 contacts the mounting surface through the shock-absorbing pad 17 at the bottom. When the equipment vibrates during operation, the transverse V-groove 11 at the bottom of the outer rubber pad 5 and the longitudinal V-groove 12 at the bottom of the middle rubber pad 10 will deform first, absorbing vibration energy from different directions. At the same time, the large V-groove 13 between the outer pad 14 and the middle pad 15 further enhances the elastic deformation capability of the pad body 1. Combined with the high flame retardancy and cushioning and shock absorption of the outer pad 14, middle pad 15 and top pad 16 made of PE foam, the PE foam has the characteristics of flame retardancy, sound insulation and shock absorption, and can effectively play a flame retardant role and effectively attenuate the transmission of vibration. The damping pad 3 improves the stability of the adhesive sheet 4 through its own damping characteristics, while the reinforcing frame 2 provides structural support at the edges of the outer pad 14 and the top pad 16 to prevent excessive deformation or damage to the pad body 1 during long-term use, thereby ensuring that the battery bracket 18 works in a stable state.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
