A shock absorbing device for a battery box of a new energy vehicle

Abstract

The invention discloses a shock absorbing device for a battery box of a new energy vehicle, comprising a bottom plate, two baffles are fixedly connected to the upper surface of the bottom plate, and the backs of the two baffles are fixedly connected to the front of the first side plate, The lower surface of the first side plate is fixedly connected with the upper surface of the bottom plate. The damping device of the new energy vehicle battery box is provided with a bottom plate, a second slide bar, a second slide sleeve, a box body, a third support plate, a third slide block, a third chute, a telescopic rod, a third spring and Press the plate, the tension of the third spring drives the third spring to elongate, so that the elongation of the third spring drives the telescopic rod to move upward, so that the telescopic rod drives the third support plate to move upward, so that the third support plate drives the second slide bar to move upward, The second slide bar drives the bottom plate to move upwards, so that the bottom plate drives the battery case to move upwards, so that the battery case does not shake greatly while the turbulence is large, thereby ensuring the service life of the battery.

Description

technical field [0001] The invention relates to the technical field of battery boxes of new energy vehicles, in particular to a shock absorbing device for battery boxes of new energy vehicles. Background technique [0002] As the main energy storage device loaded with batteries on the electric vehicle, the battery pack box is a key component of the electric vehicle and directly affects the performance of the electric vehicle. [0003] The existing battery fixing device has poor shock absorption effect. After long-term driving on bumpy roads, the life of the battery is likely to be affected by the vibration of the car. At the same time, the fixing method of the battery is prone to failure. At the same time, the base of the device will pop up, causing the battery to shake, and there are no corresponding shock absorbers on the left and right sides of the battery. When the car shakes, the battery will vibrate left and right, which will affect the life of the battery. The bottom...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a shock absorbing device for the battery box of a new energy vehicle, which solves the problem that the base of the device will bounce up when the bump is large, causing the battery to shake, and the left and right sides of the battery There is no corresponding shock absorbing device. When the car shakes, the battery will vibrate left and right, which will affect the life of the battery, and the bottom of the battery is only supported by a connecting rod. The long-term bumping will damage the connecting rod.
