Description

Technical Field

[0001] The utility model relates to the technical field of automobile batteries, in particular to a new energy automobile battery module. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] After a fire occurs in the existing new energy vehicle battery module, the vehicle is generally difficult to escape the fire and is difficult to rescue. The main reason is that the local fire can easily spread to the entire battery module. Without isolation measures, it will become a full combustion within a few minutes, resulting in great losses. Therefore, we propose a new energy vehicle battery module. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] A new energy vehicle battery module provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-2 As shown, the utility model provides a new energy vehicle battery module, including: a battery assembly 100 and a heat dissipation assembly 200; wherein the battery assembly 100 includes a battery box 110 and a battery block 120 arranged in the battery box 110.

[0023] The heat dissipation assembly 200 is arranged on the battery box 110, and the heat dissipation assembly 200 includes a water tank 210 installed on the battery box 110, a heat dissipation water plate 220 fixed between the battery blocks 120 and connected to the water tank 210, a water outlet 230 opened on the heat dissipation water plate 220 and located on the top side of the battery box 110, a torsion spring shaft 240 installed on the heat dissipation water plate 220 and located above the water outlet 230, a baffle 250 fixed on the torsion spring shaft 240, a mounting frame 260 installed on the inner side of the battery box 110, a traction rope 270 connected to the baffle 250 and passing through the mounting frame 260, a fixing block 280 connected to the end of the traction rope 270 and located on the inner side of the mounting frame 260, and a compression spring 290 arranged in the fixing block 280.

[0024] Further, the fire extinguishing assembly 300 is arranged on the mounting frame 260, and the fire extinguishing assembly 300 includes a sleeve 310 installed on the mounting frame 260, a positioning rod 320 sleeved on the sleeve 310 and hanging to the side of the fixing block 280, a traction rope 330 connected to the positioning rod 320 and extending outward from the top of the sleeve 310, a mounting plate 340 installed on the side of the sleeve 310, a mixed gas fire extinguishing airbag 350 fixed to the mounting plate 340 and connected to the traction rope 330, a fixing plate 360 ​​installed on the side of the mounting frame 260 and a needle 370 arranged on the fixing plate 360, through the heat dissipation assembly 200 and the fire extinguishing assembly 300 After a fire occurs in the battery block 120, the mixed gas fire extinguishing agent in the mixed gas fire extinguishing airbag 350 will expand, and then the positioning rod 320 will be pulled upward to separate from the fixed block 280. Under the action of the compression spring 290, the fixed block 280 moves horizontally, and then the baffle 250 is pulled open through the traction rope 270, so that the cooling water in the water tank 210 is discharged along the water outlet 230 on the heat dissipation plate 220 to extinguish the battery block 120. At the same time, the mixed gas fire extinguishing airbag 350 will continue to expand and contact the needle 370 and then rupture, and the mixed gas fire extinguishing agent therein will cover the battery block 120 below, thereby achieving a double fire extinguishing effect, which can effectively reduce the loss caused by the combustion of the battery module.

[0025] Specifically, the water tank 210 is provided with heat dissipation fins 211 , and the heat dissipation fins 211 can be used to dissipate the heat of the cooling water in the water tank 210 , thereby ensuring the heat dissipation effect on the battery block 120 .

[0026] Furthermore, a wire groove 221 is provided on the heat dissipation water plate 220 to facilitate the passage of the connection wires on the battery block 120 , which is more reasonable.

[0027] On the other hand, a sealing block 251 located in the water outlet hole 230 is fixed on the baffle plate 250, which can seal the water outlet hole 230 under normal circumstances to prevent cooling water from leaking.

[0028] It should be noted that the end of the traction rope 330 is connected to the side of the mixed gas fire extinguishing airbag 350 close to the fixed plate 360. After the mixed gas fire extinguishing airbag 350 is inflated, the traction rope 330 can move the positioning rod 320 upward so that the positioning rod 320 no longer blocks the fixed block 280, thereby facilitating the compression spring 290 to bounce up and pull the baffle 250, which is highly practical.

[0029] Furthermore, the mixed gas fire extinguishing airbag 350 is a gas mixed with nitrogen, argon and carbon dioxide in a certain proportion. It is stable at ordinary times and expands when heated.

[0030] On the other hand, the traction rope 270 is connected to the bottom of the baffle 250 , so that the baffle 250 can be pulled up to a larger angle, so that the cooling water can flow out of the water outlet 230 quickly.

[0031] The working principle and use process of the utility model are as follows: first, after a fire occurs in the battery block 120, the mixed gas fire extinguishing agent in the mixed gas fire extinguishing airbag 350 will gradually expand, and then the positioning rod 320 will be pulled upward to separate from the fixed block 280. Under the action of the compression spring 290, the fixed block 280 will move horizontally, and then the baffle 250 will be pulled open by the traction rope 270, so that the cooling water in the water tank 210 is discharged along the water outlet 230 on the heat dissipation water plate 220 to extinguish the battery block 120. At the same time, the mixed gas fire extinguishing airbag 350 will continue to expand and contact the needle 370 and then rupture, and the mixed gas fire extinguishing agent therein will cover the battery block 120 below, thus achieving a double fire extinguishing effect.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
