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...

The invention discloses a power battery pack installing assembly of a new energy source vehicle, and is used for solving the problems of deformation occurrence and burning explosion in the impact processes of the existing battery assembly. The power battery pack installing assembly comprises a first tray, a second tray, a third tray, a torsional spring, a first deformation strip, a second deformation strip, a deformation plate and safety pins, wherein the first tray and the second tray are connected with the torsional spring, the first deformation strip and the second deformation strip through the safety pins; the second tray and the third tray are connected through the deformation plate; the impact energy is absorbed in a deformation mode in the impact process. The power battery pack installing assembly has the advantages that the internal structure of the existing battery is not changed; the installing structure of the battery assembly is changed, so that in the vehicle impact process, the collision force is effectively buffered and absorbed through absorbing the impact energy; the maintenance is convenient; the maintenance cost is reduced.
Description
technical field [0001] The invention relates to the technical field of power batteries used in new energy vehicles and their fixation, specifically the installation components of power battery packs for new energy vehicles. 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 th...
