Description

Technical Field

[0001] The present invention relates to the technical field of battery pack protection, and in particular to an impact-resistant, collision-resistant and flame-retardant device for a new energy vehicle battery pack based on a polyurethane urea elastomer composite material. Background Art

[0002] With the widespread promotion and rapid development of new energy vehicles, batteries, as their core energy components, are becoming increasingly important in vehicle design, with their operational stability and safety becoming key elements. The battery pack not only provides energy for the vehicle, but its ability to withstand shock, vibration, collisions, and flame retardancy under complex operating conditions is also directly related to the safety performance of the entire vehicle. Currently, new energy vehicles are susceptible to various factors during operation, including road bumps, side collisions, and internal thermal runaway. Once these issues affect the battery pack, they can damage the battery structure, deform the battery cells, and even cause serious safety incidents such as fires and explosions. Therefore, improving the battery pack's impact resistance, collision resistance, and fire response capabilities under actual operating conditions is a core issue in ensuring the safe and stable operation of new energy vehicles.

[0003] However, in actual applications, many existing battery protection structures fail to adequately account for the continuous vibrations experienced in complex road environments. This results in long-term fatigue impacts on the battery pack, which can easily lead to structural loosening, cell damage, and even battery performance degradation. Most traditional structures utilize rigid materials or simple position-limiting structures, lacking sufficient elastic buffering and multi-dimensional position-limiting mechanisms to effectively absorb external impact forces and prevent battery displacement. Current battery pack fire protection designs are mostly passive, lacking rapid suppression and spread-blocking capabilities. Once a battery fire occurs, it can spread rapidly, causing greater damage. During battery maintenance and replacement, many structural designs are complex and difficult to disassemble and assemble, impacting both efficiency and safety. Therefore, we offer impact-resistant, anti-collision, and flame-retardant devices for new energy vehicle battery packs based on polyurethane urea elastomer composites. Summary of the Invention

An energy storage battery 410 is provided on the side of the isolation plate frame 46 away from the docking device 47 in the outer box 41, and 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 box 41, the outer surface of the installation and fixing frame 44 is nested between the outer box 41 and the end side plate 42, the two side limiters of the connecting handle frame 43 are installed between the installation and fixing frame 44 and the end side plate 42, the installation top cover 45 is placed between the installation and fixing frame 44, and the outer surface of the isolation plate frame 46 is nested in the outer box 41;

The connecting handle 43 in the outer bag 41 makes it more convenient for the staff to operate during actual use, thereby further improving its practicality during actual use.

[0052] Working principle:

[0053] like Figure 1-7 As shown, when using this battery pack to protect a car battery, the battery to be protected can first be embedded and installed from the side between the two side frames 11 located inside the battery pack. This side nesting design facilitates quick placement and securement of the battery and improves the stability of the overall structure. The battery pack's housing mechanism 1 is structurally encapsulated and secured by installing a top plate and a bottom plate on the top and bottom of the side frames 11, respectively, to form a complete enclosure.

[0054] The bottom plate incorporates a silicone pad 15 embedded within its inner connecting ribs 14 to provide cushioning protection for the battery during vehicle operation. The silicone pad 15 has excellent elasticity and shock-absorbing properties, effectively absorbing vibration and impact generated during vehicle operation. This prevents damage to the battery casing, loosening, or poor contact caused by prolonged vibration, significantly enhancing the battery's durability and safety during use.

[0055] The top plate mechanism 2, with its internal connecting ribs 22 and steel frame 24, forms a stable restraining frame. This not only further secures the battery's position and prevents it from swaying within the vehicle, but also, in the event of a battery failure such as overheating or fire, the special fire-fighting material of the connecting ribs 22 provides insulation and fire protection, effectively suppressing the upward spread of fire. This design organically combines structural restraint with safety protection, significantly enhancing fire protection capabilities while improving seismic resistance, further ensuring the vehicle's operational safety under extreme operating conditions.

[0056] To further enhance overall fire safety, the battery pack features independent fire extinguishing mechanisms 3 on either side of the side frames 11. Workers can precisely install the docking frame 31 between the two side frames, effectively linking the fire extinguishing system with the battery area. In actual operation, if a battery malfunctions or fire hazard occurs, workers can remotely activate the fire extinguishing storage pump 35 through the vehicle's central control system. This pump delivers the stored fire extinguishing insulating fluid through a transfer pipe 34 to a transfer channel 32, where it is evenly sprayed by the fire extinguishing nozzle 33 at the end, quickly covering the fire area. This ensures precise fire extinguishing and insulation protection for the battery, minimizing the spread of the accident.

[0057] To improve the battery pack's energy efficiency and ease of use, a dedicated outer case 41 is installed outside the battery pack to house the energy storage battery assembly. Workers can place the energy storage battery 410 into the outer case 41 and electrically connect it to the outer case and docking station 47 via connector 411. This connection system transmits electrical energy to an energy converter 48. After conversion, the stable current is then fed into the vehicle's system via a transmission line 49, providing continuous and reliable power output.

[0058] The outer case 41 is also equipped with a connecting handle 43, which allows for flexible operation during installation, removal, or transportation. This convenient mobility not only improves maintenance efficiency but also enhances the overall adaptability and user-friendliness of the battery pack system.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
