Description

Technical Field

[0001] The utility model relates to the technical field of battery components, in particular to a flameproof battery component for new energy electric vehicles. Background Art

[0002] Electric vehicle batteries, power batteries are power sources for tools, mostly referring to batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. They are mainly different from starting batteries used to start car engines. Most of them use valve-sealed lead-acid batteries, open-type tubular lead-acid batteries, and lithium iron phosphate batteries. Frequent spontaneous combustion incidents of electric vehicles have caused many potential users of new energy to have a little worry.

[0003] At present, most existing new energy electric vehicle components use an integrated shell to protect the battery when in use, thereby reducing manufacturing steps and assembly processes, thereby reducing manufacturing costs and time. In addition, this design usually requires fewer parts and connectors, simplifies supply chain management, and improves production efficiency. However, in actual use, the integrated shell has certain defects. Since the integrated shell is usually a precision-made integral component, the cost of replacing the entire shell after damage will be very high, including material costs, labor costs and related process costs. Therefore, it is necessary to redesign a flame-proof battery component for new energy electric vehicles to address the above problems. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model provides an anti-collision beam 1 and an anti-collision beam 2. When a group of anti-collision beams 2 or 3 is damaged, the connection with the mounting frame can be released by removing the screw 2 at the end thereof, and then the anti-collision beam 1 is taken out from the clamping groove 3 and the anti-collision beam 2 is taken out from the clamping groove 1 for replacement.

[0024] With the help of the design of the engagement of the anti-collision beam 1 6 and the anti-collision beam 2 7, when the car is hit by a collision, only the damaged anti-collision beam 1 6 and the anti-collision beam 2 7 need to be replaced, and there is no need to replace the entire shell, thereby reducing the cost of replacement and maintenance. Through the cross arrangement of the anti-collision beam 1 6 and the anti-collision beam 2 7, the battery assembly can be protected from external impact to a greater extent, because the cross structure can disperse the stress more evenly, preventing a certain part from being damaged due to stress concentration, greatly reducing the possibility of direct collision damage to the battery, thereby reducing the risk of fire caused by battery damage and improving the anti-flammability effect of the battery pack.
