During operation, the electric fan 203 is powered to make it work, and the air in the inner cavity of the box body 1 is discharged through the operation of the electric fan 203, and new air is transported to the inner cavity of the box body 1 through the air inlet grille 204, so that the air in the inner cavity of the box body 1 flows, and the temperature generated by the operation of the lithium battery body 4 is taken out, thereby the lithium battery The body 4 is cooled down, and when the vehicle vibrates when driving into a pothole, the vibration causes the inner cavity of the movable sleeve rod 602 to slide on the surface of the telescopic inner rod 601, and the elasticity of the shock-absorbing spring 603 reduces the sliding amplitude of the movable sleeve rod 602, thereby achieving the purpose of shock absorption, and then the vibration is absorbed and reduced by the elasticity of the buffer spring 301, and the rebound of the buffer spring 301 is damped by the spring damper 303 to reduce the rebound force of the buffer spring 301, thereby reducing the shaking amplitude of the lithium battery body 4 and avoiding collision with the inner wall of the box body 1 during shaking.

[0033] In summary: this small lithium battery with a buffer device, through the cooperation of various components, solves the problem of existing batteries that when the vehicle moves to a pothole, the vibration causes the battery to collide with the vehicle and cause battery damage, and the heat generated by the battery during operation can cause high-temperature damage to the battery.
