Protection structure for storage battery of electric automobile

Abstract

The invention discloses a protection structure for a storage battery of an electric automobile. The structure comprises a storage battery, a bearing plate, a hemispherical cavity and a supporting part. The bearing part comprises a first ball body and a supporting seat. A spherical cavity is formed in the first ball body, and an opening is formed below the first ball body. The bottom of the first ball body is connected with a connecting plate, and the outer side of the first ball body is connected with a fixing ring. A connecting rod is fixedly connected above the supporting seat, and the top of the connecting rod is fixedly connected with a second ball body. The connecting rod passes through the opening, and the second ball body is located in the spherical cavity. A second rubber ring is connected between the connecting rod and the connecting plate. A pipe body is further connected above the supporting seat, and the connecting plate is movably inserted into the pipe body. A first rubber ring is connected between the outer side of the connecting plate and the pipe body, and the outer side of the pipe body is movably sleeved with a lantern ring. The lantern ring and the fixing ring are connected with each other through a plurality of elastic metal rods, and a first spring is connected between the connecting plate and the supporting seat.

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.
