Power battery protection device

Abstract

The utility model discloses a power battery protection device which comprises a bottom plate, a plurality of pulley blocks distributed longitudinally and transversely are arranged on the bottom plate, each pulley block comprises a pulley and mounting racks arranged on the two sides of the pulley, a plurality of mounting holes are formed in the edge of the bottom plate, and the bottom plate is detachably connected with a battery pack through the mounting holes. Compared with the prior art, the power battery pack protection device has the advantages that a vehicle with a power battery pack at the bottom can be protected by the aid of the pulley block. When the vehicle runs and the bottom encounters an obstacle, the collision friction force between the obstacle and the bottom of the vehicle can be converted into rolling kinetic energy to be released, so that the purpose of protecting the battery pack is achieved; the utility model has the advantages of simple structure and low manufacturing cost.

Description

TECHNICAL FIELD

[0001] The utility model relates to new energy automobile technical field, concretely is a power battery protection device. BACKGROUND

[0002] With the rise of new energy vehicles, a large number of new energy vehicles enter thousands of households. When the vehicle loaded with power battery travels on the road, the probability of being bottomed by foreign matter is greatly increased. Most of the current power batteries are suspended at the bottom of the vehicle, and when bottomed by foreign matter, the power battery is scratched and leaks water at least, and the power battery cell is punctured and causes fire at most. A pure electric new energy vehicle, the value of power battery generally accounts for 40%-60% of the whole vehicle value, once the power battery is scratched, it will cause major loss of personal property, and serious fire will cause serious adverse effects on the industry and society. UTILITARY MODEL CONTENT

[0003] The utility model aims at providing a power battery protection device to solve the problems in the above background technology.

[0004] To achieve the above object, the utility model provides the following technical scheme: a power battery protection device, comprising a bottom plate, a plurality of slide pulley groups are arranged on the bottom plate in longitudinal and transverse directions, the slide pulley group comprises a slide pulley and mounting frames arranged on both sides of the slide pulley, a plurality of mounting holes are arranged on the edge of the bottom plate, and the bottom plate is detachably connected with the battery pack through the mounting holes.

[0005] Preferably, the mounting frame comprises a mounting base and a supporting column, and the supporting column is vertically mounted on the mounting base.

[0006] Preferably, the two mounting frames are arranged side by side in a group, and the slide pulley is arranged between the two mounting frames.

[0007] Preferably, a fixing hole is arranged on the mounting base, and the mounting base is connected with the bottom plate through a screw.

[0008] Compared with the prior art, the utility model has the beneficial effects that: the utility model can protect the vehicle with the power battery pack at the bottom by arranging the slide pulley group. When the vehicle encounters an obstacle during driving, the frictional force between the obstacle and the bottom of the vehicle can be converted into rolling kinetic energy and released, so that the purpose of protecting the battery pack is achieved. The utility model has simple structure and low manufacturing cost. BRIEF DESCRIPTION OF DRAWINGS
