Energy storage battery with anti-collision protection device

Abstract

The invention discloses an energy storage battery with an anti-collision protection device in the technical field of energy storage batteries. The energy storage battery comprises an energy storage battery body and a shell, wherein an anti-vibration mechanism is arranged between the bottom of an inner cavity of the shell and the lower end face of the energy storage battery body, the top end of an elastic buffering hemisphere is fixedly connected with the lower end face of the energy storage battery body, the peripheral end surface of the elastic buffering hemisphere is fixedly connected with the bottom of the inner cavity of the shell, a damping block is arranged at the top of an inner cavity of the elastic buffering hemisphere, a first spring is fixedly connected to the end, which is away from the top end of the inner cavity of the elastic buffering hemisphere, of the damping block, the other end of the first spring is fixedly connected with a connecting block, multiple groups of air holes communicated with the inner cavity of the elastic buffering hemisphere are uniformly formed in the outer surface of the elastic buffering hemisphere, and anti-collision devices are uniformly arranged between the inner side surface of the shell and the energy storage battery body. The device is simple in structure and convenient to operate, the stability between the shell and the energy storage battery body can be protected, and meanwhile, good safety is achieved.

Description

technical field [0001] The invention relates to the technical field of energy storage batteries, in particular to an energy storage battery with an anti-collision protection device. Background technique [0002] In order to avoid short circuit inside the energy storage equipment, especially between the body of the energy storage battery and the case, a commonly used technical solution is to add a certain thickness between the bottom of the body of the energy storage battery and the case. The thickness of the insulating cell supporting plate is generally more than 1mm. Since it occupies a certain amount of internal space of the energy storage equipment, the size of the energy storage battery body needs to be reduced accordingly, which reduces the quality and energy density characteristics of the energy storage equipment to a certain extent. In addition, since the supporting plate is freely placed between the bottom of the energy storage battery body and the shell, the vibrati...

[0002] In order to avoid short circuit inside the energy storage equipment, especially between the body of the energy storage battery and the case, a commonly used technical solution is to add a certain thickness between the bottom of the body of the energy storage battery and the case. The thickness of the insulating cell supporting plate is generally more than 1mm. Since it occupies a certain amount of internal space of the energy storage equipment, the size of the energy storage battery body needs to be reduced accordingly, which reduces the quality and energy density characteristics of the energy storage equipment to a certain extent. In addition, since the supporting plate is freely placed between the bottom of the energy storage battery body and the shell, the vibration during actual use will cause the relative movement of the energy storage battery body and the shell, which will cause the short circuit of the positive and negative electrodes. , in the existing technology, the body of the internal energy storage battery cannot be lowered and fixed, and it does not have the function of anti-collision buffer, which will cause the shell to be damaged when it is hit. Therefore, we propose an energy storage battery with an anti-collision protection device Battery
