Battery shock absorption device of new energy automobile

Abstract

A battery shock absorption device of a new energy automobile comprises a fixing block and two U-shaped blocks, a cavity is formed in the fixing block, the upper side wall and the lower side wall of the cavity are inclined faces and are parallel to each other, the two inclined faces are each provided with at least one sliding groove in the inclined direction of the inclined faces, and each sliding groove is in sliding fit with a sliding block. The opposite faces of the sliding blocks in the vertical direction are fixedly connected with the outer wall of the new energy automobile battery pack. The bottoms of the two U-shaped blocks are hinged to the left side face and the right side face of the cavity through hinge shafts, the hinge shafts are sleeved with torsion springs, and one ends of the torsion springs are connected with the U-shaped blocks. According to the device, the problem that the service life of the battery is influenced due to the fact that the interior of the battery is damaged by upward or downward bending stress for many times because the battery of the new energy automobile is relatively large and a cantilever beam effect is easily generated in the up-down shaking process of the battery is solved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery shock absorber for new energy vehicles. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., and their exhaust emissions are relatively low. At present, most of the new energy vehicles on sale in the Chinese market are hybrid vehicles and pure electric vehicles. [0003] When the car encounters a bumpy road during driving, it will transmit the vibration to the battery of the new energy vehicle through the tires. The battery shock absorbers of the existing new energy vehicles mostly slow down the vibration by setting multiple springs above and below the battery, but Due to the large battery of new energy vehicles, the cantilever beam effect is likely to occur when the battery is shaking up and d...

Problems solved by technology

[0003] When the car encounters a bumpy road during driving, it will transmit the vibration to the battery of the new energy vehicle through the tires. The battery shock absorbers of the existing new energy vehicles are mostly The vibration is slowed down by setting multiple springs above and below the battery. However, due to the large size of the new energy vehicle battery, the cantilever beam effect is likely to occur when the battery shakes up and down, causing the inside of the battery to be repeatedly subjected to upward or downward bending stress. damage and affect battery life, so design a battery shock absorber for new energy vehicles
