Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pack protection, in particular to a new energy automobile battery pack anti-collision and flame-retardant device based on a polyurethane urea elastomer composite material. BACKGROUND

[0002] With the wide promotion and rapid development of new energy vehicles, the running stability and use safety of batteries as the core energy components gradually become the key link in the design of the whole vehicle. The battery pack not only bears the task of providing energy for the vehicle, but also directly relates to the safety performance of the whole vehicle in terms of anti-impact, anti-vibration, anti-collision and flame-retardant ability under complex working conditions. The current new energy vehicles are easily affected by road bumps, side collision accidents, internal thermal runaway and other factors during operation. Once these problems act on the battery pack, it may cause the battery structure to be damaged, the battery cell to be deformed, and even cause serious safety accidents such as fire and explosion. Therefore, how to improve the anti-impact, anti-collision and fire response ability of the battery pack under actual operating conditions is the core issue to ensure the safe and stable operation of new energy vehicles.

[0003] However, the battery protection structure in the prior art still has many problems in actual application. For example, the battery installation structure does not fully consider the continuous vibration under complex road conditions, which causes the battery pack to be subjected to fatigue impact for a long time, easily causing structural loosening, battery cell damage and even battery performance degradation. Most traditional structures use rigid materials or simple limiting structures, lack sufficient elastic buffering and multi-dimensional limiting mechanisms, and cannot effectively absorb external impact force and prevent battery displacement. The current battery pack fire prevention design is mostly passive response type, lacks rapid suppression and spread blocking function, and once the battery catches fire, it is easy to spread rapidly and cause greater loss. In the process of battery maintenance and replacement, many structure designs are complex and inconvenient to disassemble and assemble, affecting work efficiency and safe operation. Therefore, we provide a new energy automobile battery pack anti-collision and flame-retardant device based on a polyurethane urea elastomer composite material. SUMMARY

[0047] Example 3

[0048] like Figures 1-7 As shown, a battery mechanism 4 is provided between the two side frames 11. The battery mechanism 4 includes an outer box 41. One end of the outer box 41 is provided with an end side plate 42. A connecting handle frame 43 is provided on the end side plate 42. An installation and fixing frame 44 is provided on the outer box 41. An installation top cover 45 is provided on the installation and fixing frame 44. An isolation plate frame 46 is provided in the outer box 41. A connector 47 is provided on one side of the isolation plate frame 46. A converter 48 is provided at one end of the connector 47. A transport line 49 is provided in the converter 48. An energy storage battery 410 is provided in the outer box 41 on the side of the isolation plate frame 46 away from the connector 47. A connector 411 is provided at one end of the energy storage battery 410.

[0049] The outer surface of the end side plate 42 is nested in the outer case 41, the outer surface of the mounting frame 44 is nested between the outer case 41 and the end side plate 42, the two sides of the connecting handle bracket 43 are limited between the mounting frame 44 and the end side plate 42, the mounting top cover 45 is placed between the mounting frame 44, and the outer surface of the isolation plate bracket 46 is nested in the outer case 41.

[0050] The two ends of the converter 48 are respectively connected to the converter 48 and the isolation board frame 46, one end of the transport line 49 is connected to the converter 48, one end of the connector 411 is connected to the storage battery 410, and the other end of the connector 411 is connected to the adapter 47 on the isolation board frame 46.

[0051] In this embodiment, in order to further improve the practicability in actual use, a corresponding outer box 41 is arranged on the outer surface of the battery, and the staff can place the storage battery 410 in the outer box 41 and connect the connector 411 to the outer box 41 and the adapter 47, so that the adapter 41 can be used by transmitting electric energy to the converter 48 and transporting the transport line 49 to the car, and the connecting handle 43 in the outer box 41 can be more convenient for the staff to operate in actual use, thereby further improving the practicability in actual use.

[0052] Working principle:

[0053] As shown in Figures 1-7 In the process of using the battery pack to protect the car battery, the battery to be protected can be first embedded from the side between the two side frames 11 arranged inside the battery pack. This side-embedded design facilitates quick placement and fixation of the battery and improves the stability of the overall structure. The shell mechanism 1 of the battery pack is encapsulated and fixed by installing a top plate and a bottom plate on the top and bottom of the side frame 11, respectively, to form a complete wrapping structure.

[0054] The bottom plate is embedded with a silica gel pad 15 in the connecting bone 14 on the inner side to achieve buffering protection of the battery during vehicle driving. The silica gel pad 15 has good elasticity and shock absorption performance, which can effectively absorb the vibration and impact generated during vehicle operation, prevent the battery shell from being damaged, loose or poorly contacted due to long-term vibration, and significantly enhance the durability and safety of the battery during use.

[0055] The top plate mechanism 2 forms a stable limiting frame with the connecting bone 22 and the steel plate frame 24 inside it, which not only further fixes the position of the battery to prevent it from shaking in the car, but also uses the special fire-fighting material of the connecting bone 22 to play a role in heat insulation and fire prevention when the battery fails, such as overheating or fire, effectively inhibiting the upward spread of the fire. This design combines structural limiting and safety protection, improves the anti-shock performance, and significantly enhances the fire protection capability, thereby further ensuring the running safety of the whole vehicle under extreme working conditions.

[0056] To further enhance the overall fire safety performance, the battery pack is also provided with independent fire extinguishing mechanism 3 on both sides of the side frame 11. The staff can accurately install the docking sleeve frame 31 between the two side frames, so that the fire extinguishing system and the battery area form an effective linkage. In actual operation, if the battery fails or has a fire hazard, the staff can remotely start the fire extinguishing storage pump 35 through the car central control system, so that it delivers the stored fireproof insulation liquid to the transmission channel 32 through the transmission pipe 34, and is uniformly sprayed out by the end fire nozzle 33, quickly covering the fire area, realizing accurate fire extinguishing and insulation protection of the battery, and maximizing the containment of safety accidents.

[0057] In addition, in order to improve the energy utilization and operation convenience of the battery pack, a dedicated outer box 41 is provided outside the battery, which is used to integrate the energy storage battery assembly. The staff can place the energy storage battery 410 in the outer box 41, and complete the electrical connection with the outer box body and the adapter 47 through the connector 411. The electric energy will be delivered to the electric energy converter 48 through the connection system, and after conversion processing, the stable current will be input into the vehicle system through the transmission line 49, providing continuous and reliable power output for the vehicle.

[0058] In terms of structural design, the outer box 41 is also equipped with a connecting handle 43, which facilitates flexible operation of the staff during installation, disassembly or transportation. This convenient mobility not only improves the maintenance efficiency, but also enhances the overall adaptability and user-friendliness of the battery pack system.

Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
