Battery pack structure

Abstract

The invention discloses a battery pack structure, and provides a battery pack structure, which has the advantages that the structure is simple, the safety and reliability are realized, the assembly process is convenient and rapid, and the manufacturing cost is reduced. The battery pack structure solves the technical problems of complicated and long assembly process of a battery pack, waste of time and labor, consumption of a large amount of manpower and material resources, poor safety and reliability, failure to ensure the quality of a battery pack product and the like in the prior art. The battery pack structure comprises a box body, wherein the box body is used for placing battery cells; the inner ring surface of the box body corresponding to the outer ring surface of each battery cell extends inwards to form a battery cell fixing plate; the bottom surface, corresponding to the bottom surfaces of the battery cells, of the box body extends inwards to form a plurality of limiting bosses; the battery cell fixing plates and the limiting bosses together define a battery cell module space, and the battery cells are assembled and installed in the battery cell module space, and are clamped into limiting grooves formed by the adjacent limiting bosses.

Description

Technical field [0001] The invention relates to a battery pack structure, in particular to a battery pack structure with simple structure, convenient and quick assembly process, and reduced manufacturing cost. Background technique [0002] The existing battery pack structure usually requires the battery cells to be assembled into a module structure first, and then the assembled module structure is assembled into a box to form a battery pack system. The assembly process is cumbersome and time-consuming, time-consuming and laborious, and wastes a lot of manpower and material resources. At the same time, due to the need for secondary assembly after transportation during the assembly process, the safety and reliability are poor, and the quality of the battery pack product cannot be guaranteed. In addition, because the existing battery pack structure often does not have a cooling structure, when the battery pack is discharged at a high rate and generates a lot of heat in some special ...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly provides a battery pack structure with simple structure, safety and reliability, convenient and quick assembly process, and reduced manufacturing cost, which solves the cumbersome and time-consuming battery pack assembly process in the prior art, which is time-consuming and labor-intensive, and wastes a lot of manpower Technical problems such as material resources, poor safety and reliability, and inability to guarantee the quality of battery pack products

[0004] The present invention also provides a battery pack structure that can automatically expand the box body to dissipate heat outside after the temperature rise of the battery pack, which solves the problem that the heat of the battery pack in the prior art cannot be dissipated in time, which not only affects the performance of the battery Play a huge impact, but there are also technical problems such as huge security risks
