New energy automobile battery protection device

Abstract

The invention discloses a new energy automobile battery protection device, and relates to the technical field of new energy batteries. the invention aims to solve the life problem; the device specifically comprises a shell, a battery placement mechanism is arranged in the shell, the battery placement mechanism comprises four sets of damping assemblies, a placement base and a clamping assembly, thefour sets of damping assemblies are arranged at the four corners of the bottom of the placement base correspondingly, and each set of damping assembly comprises three sets of damping rods and six sets of universal ball structures; the top and the bottom of each set of damping rods are movably connected to the inner wall of the bottom of the shell and the outer wall of the bottom of the placementbase through universal ball structures respectively, the three sets of damping rods form a triangular pyramid structure, each damping rod comprises a first sleeve and a second sleeve, and the inner wall of the first sleeve and the inner wall of the second sleeve are movably connected with the same piston rod. According to the device, a spring II can be effectively prevented from being subjected tonon-axial displacement and spiral torque, the spring II can be well protected, and the service life thereof is prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a battery protection device for new energy vehicles. Background technique [0002] The new energy vehicle battery is the power battery, that is, the power supply that provides the power source for the tool. It mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starter battery used for starting the car engine. Valve-port sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used. [0003] After searching, the Chinese Patent Publication No. is CN211455783U, which discloses a new energy vehicle battery protection device, including a protective shell, the inner bottom wall of the protective shell is fixedly connected with a buffer pad, and the top of the buffer pad is fixedly connected with a second One spring, o...

Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: it uses horizontal and vertical springs to protect the battery, but when the spring absorbs shock, it not only has an axial displacement, but also a vertical displacement to the axial direction, and is also subjected to torque, making the spring easy to move. break at fatigue limit
