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] like 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 expanded state. The controller is configured to issue the detonation command when the vehicle collides with the vehicle.

Abstract

The present invention provides a power battery pack safety device for a vehicle, comprising: a power battery pack for supplying power to the vehicle; an air bag capable of expanding from a contracted state to an expanded state; wherein the air bag is arranged to adjacent to the power battery pack and between the power battery pack and the ground in the unfolded state; a gas generator for detonating when receiving a detonation instruction to blast the air bag in the retracted state providing gas to inflate the air bag from the deflated state to the deployed state; and a controller configured to issue the detonation command in the event of a collision with the vehicle. The present invention directly uses the protection function of the air bag to protect the battery pack, cuts off the contact between the power battery pack and the ground or other sundries in time, and avoids the power battery pack from being subjected to secondary disasters such as friction, puncture or extrusion. Occurrence, to achieve a better role in advance protection, to protect the safety of life and property of passengers.

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...
