Problems solved by technology

Its working principle: when charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and convert chemical energy into electric energy output again when discharging. In recent years, batteries have been used more and more widely. Power tools and new energy vehicles are used in the fields of power tools and new energy vehicles. During work, bumps and vibrations will impact the battery pack, and the battery will also be impacted, which often leads to damage to the battery pack and battery, shortening the service life, and frequently replacing the battery pack. , increase the cost

Abstract

The invention provides an impact-resistant battery pack. A first buffering device and second buffering devices are arranged between an inner box and an outer box, so that the condition that battery cells in the battery pack is prevented from being damaged when the battery pack is bumped and impacted is ensured due to the buffering effect of buffering grids and springs, and thus service life is prolonged and cost is saved. Flexible connection of a plurality of battery cell support units is achieved via cooperation of splicing blocks and splicing grooves and cooperation of first installation grooves and I-shaped blocks, replacement efficiency of the battery cells is improved, and meanwhile each battery cell is separated from another one by using the battery cell support unit, so that a short circuit risk caused by broken skin of the battery cells is avoided; two bottom frames are connected by an upper support arm and a lower support arm to form a stable support structure, and thus mechanical strength of the battery cell support is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an impact-resistant battery pack. Background technique [0002] The battery industry is an important part of the new energy field and a new hotspot of global economic development. The battery industry is closely related to the development of electric power, transportation, and new industries. status. The storage battery plays a decisive role in the battery industry. The storage battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction. It usually refers to a lead-acid battery. It is a kind of battery and belongs to secondary battery. Its working principle: when charging, the external electric energy is used to regenerate the internal active material, the electric energy is stored as chemical energy, and the chemical energy is converted into electric energy out...
