A battery protection structure for electric vehicles

Abstract

The invention discloses a battery protection structure for an electric vehicle, which comprises a battery, a load-bearing plate, a hemispherical cavity and a support part. The support part comprises a first sphere and a support seat. A spherical cavity is opened inside the first sphere. There is an opening at the bottom, the bottom of the first sphere is connected to the connecting plate, the outer side of the first sphere is connected to a fixed ring, the top of the support base is fixedly connected to a connecting rod, the top of the connecting rod is fixedly connected to a second sphere, and the connecting rod passes through the opening. The second sphere is located in the spherical cavity, the second rubber ring is connected between the connecting rod and the connecting plate, the pipe body is connected above the support seat, the connecting plate is movably inserted in the pipe body, and the outer side of the connecting plate and the pipe body are connected. The first rubber ring is connected, the outer movable sleeve of the pipe body is provided with a collar, the collar and the fixed ring are connected to each other through several elastic metal rods, and the first spring is connected between the connecting plate and the support seat. The present invention can improve the current There are technical deficiencies, with better shock absorption.

Description

technical field [0001] The invention relates to an electric vehicle device, in particular to an electric vehicle storage battery protection structure. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Because the impact on the environment is relatively small compared with traditional cars, its prospects are widely optimistic. Electric vehicles do not generate exhaust gas when working with internal combustion engine vehicles, and do not produce exhaust pollution. It is very beneficial to environmental protection and air cleanliness, almost "zero pollution" ". Although the traditional installation shell of the battery for electric vehicles has a shock-absorbing structure, the shock-absorbing effect is poor, thereby affecting the service life of the battery.

AI Technical Summary

Problems solved by technology

The battery housing for electric vehicles with this structure is equipped with vertical shock absorbers and lateral shock absorbers, which can perform vertical and lateral shock absorption on the battery housing, thereby performing multi-directional shock absorption and buffer protection for the battery, but this The shock absorption effect of this device is average, and it cannot effectively prevent the battery from shaking and collision damage caused by the driving of the car, thus limiting its scope of application.
