Embodiment Construction
[0028] Figure 1 to Figure 5 An embodiment of a traction battery pack safety device for a vehicle according to the present invention is shown.
[0029] Such as Figure 1 to Figure 4 As shown, the power battery pack safety device for a vehicle may generally include a power battery pack 1 , an air bag 2 , a gas generator 3 and a controller not shown. The power battery pack 1 is used to provide power for the vehicle. The air bag 2 is capable of inflating from a contracted state to an expanded state. The air bag 2 may be arranged adjacent to the power battery pack 1 and between the power battery pack 1 and the ground 4 in the unfolded state. The gas generator 3 is used for detonating to provide gas to the air bag 2 in the contracted state when receiving the detonation instruction, so that the air bag 2 expands from the contracted state to the deployed state. The controller is configured to issue the detonation command when the vehicle collides with the vehicle.

The invention provides a power battery pack security device for vehicles. The power battery pack security device comprises a power battery pack, a gas bag, a gas generator and a controller, wherein the power battery pack is used for providing power for a vehicle; the gas bag can expand from a contracting state to an expanded state, is arranged close to the power battery pack and is located between the power battery pack and the ground when in the expanded state; the gas generator is used for initiation when receiving an initiation command to provide gas for the gas bag in the contracting state, so that the gas bag can expand from the contracting state to the expanded state; and the controller is configured to send the initiation command in case of a collision accident of the vehicle. According to the power battery pack security device, the protection function of the gas bag is directly used for protecting the battery pack, and the contact between the power battery pack and the ground or other sundries is cut off immediately, so that the power battery pack is protected against such secondary disasters as friction, puncture, extrusion or the like, and accordingly, a relatively good in-advance protection role is played, and the lift and property security of passengers are protected.
Description
technical field [0001] The invention relates to a battery pack safety device, in particular to a power battery pack safety device for vehicles. Background technique [0002] With the shortage of energy and the increasingly serious environmental pollution, major automobile OEMs are vigorously developing new energy vehicles. As a kind of new energy vehicles, electric vehicles are becoming more and more popular due to their advantages of environmental protection and energy saving, and the popularity and use of electric vehicles are gradually increasing. Electric vehicles usually use power battery packs to store electrical energy to power the vehicle during operation. [0003] When an electric vehicle crashes, the vehicle components around the power battery pack may rub against the battery pack, accumulate the battery pack or even puncture into the battery pack, which may cause the battery pack to explode and cause a fire. In this way, in addition to the injuries caused by the...
