Embodiment Construction

[0033] Such as Figure 1 to Figure 12 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0034] What is developed is a device for protecting power batteries such as storage batteries in new energy vehicles, especially to prevent the battery from being twisted and deformed when the car is subjected to violent impacts.

[0035] The basic principle is that after a car is violently hit, the impact on the battery is different according to the impact location and direction. The biggest, the current mainstream design method is to optimize the layout of the battery core, and the battery core is fixed in the battery case, the impact is still not released, resulting in the dismemberment of the battery components, which in turn leads to a deflagration accident.

[0036] In the side impact of the car, the speed is not high, but because the battery cells are superimposed in the front and rear directions, the bonding strength in the side dir...

Abstract

The invention discloses a power battery pack with a buffer function, which is used to solve the problems of deformation and explosion of the existing battery components during the impact process. It includes a battery case assembly containing a battery cell assembly inside, and is characterized in that it also includes a first tray, a second tray, a third tray, a torsion spring, a first deformation bar, a second deformation bar, a deformation plate and a safety Pin, wherein, the first pallet and the second pallet are connected through a safety pin and torsion spring, the first deformation bar, and the second deformation bar, and the second pallet and the third pallet are connected through a deformation plate. In the process, the impact energy is absorbed by deformation. The present invention does not change the internal structure of the existing battery, but by changing the installation structure of the battery assembly, in the process of vehicle collision, by absorbing the energy of the collision, more effective cushioning and absorption of the collision force is realized, which is convenient for maintenance. Reduce maintenance costs.

Description

technical field [0001] The invention relates to the technical field of power batteries used in new energy vehicles and their fixation, specifically power battery packs with a buffer function. Background technique [0002] With the shortage of energy, rising oil prices, and increasingly serious pollution of the urban environment, the development of new energy alternatives to petroleum products has been paid more and more attention by governments. In the field of vehicles, pure electric and hybrid vehicles will become the future development of the automotive industry. inevitable trend. In the new energy electric vehicle and hybrid electric vehicle system, the power battery system is an indispensable and important part of it. However, the safety of the electric vehicle power system (power battery pack) has always restricted the rapid development of electric vehicles. The number is getting larger and larger, traffic accidents are frequent, and the requirements for the safety an...
