Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a cell support boss structure. Background Technology

[0002] When placing aluminum busbars, the orientation of the busbars is inconsistent because there is no positioning between the battery cell bracket and the aluminum busbars; or the aluminum busbars may be misaligned or moved when subjected to external force.

[0003] In addition, if there is an operational error, the aluminum bars of different polarities may come into contact, resulting in "arcing". Utility Model Content

[0004] The purpose of this utility model is to provide a protrusion structure for a battery cell bracket, which aims to solve the problem that the surface of the existing circular battery cell bracket is flat and there is no positioning structure between it and the aluminum busbar.

[0005] To achieve the above objectives, this utility model provides a battery cell support boss structure, including a support body, a positive electrode aluminum busbar, multiple bosses, multiple connecting aluminum busbars, and a cylindrical battery cell;

[0006] The cylindrical battery cell is mounted on the bracket body, the positive electrode aluminum busbar is mounted on the cylindrical battery cell, the plurality of bosses are mounted on the bracket body, and the plurality of connecting aluminum busbars are mounted on the bracket body through the plurality of bosses.

[0007] The plurality of protrusions are integrally formed with the bracket body and protrude from the upper surface of the bracket body.

[0008] The connecting aluminum busbar has a slot, which is located on the connecting aluminum busbar.

[0009] This utility model discloses a battery cell support boss structure. By placing a cylindrical battery cell inside the battery cell support and inserting connecting aluminum bars above the support body, multiple bosses on the support body cooperate with the connecting aluminum bars to limit their movement and constrain their rotation or movement. This compensates for slippage defects in the production process and improves the yield of laser welding. Above the battery cell support, the bosses on the support body can position the aluminum bars, preventing misalignment and avoiding "sparking." Furthermore, the absence of welding fixtures improves welding efficiency and quality, thus solving the problem that existing circular battery cell supports have a flat surface and lack a positioning structure between them and the aluminum bars.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0015] Please see Figures 1-2 This utility model provides a battery cell support boss structure, which includes a support body 1, a positive electrode aluminum busbar 2, multiple bosses 3, multiple connecting aluminum busbars 4 and a cylindrical battery cell 5;

[0016] The cylindrical battery cell 5 is mounted on the bracket body 1, the positive electrode aluminum busbar 2 is mounted on the cylindrical battery cell 5, the plurality of bosses 3 are mounted on the bracket body 1, and the plurality of connecting aluminum busbars 4 are mounted on the bracket body 1 through the plurality of bosses 3.

[0017] Furthermore, the plurality of protrusions 3 are integrally formed with the bracket body 1 and protrude from the upper surface of the bracket body 1.

[0018] Furthermore, the connecting aluminum busbar 4 has a slot 21, which is located on the connecting aluminum busbar 4.

[0019] In this embodiment, by placing the cylindrical battery cell 5 inside the battery cell bracket and placing the connecting aluminum busbar 4 above the bracket body 1, and simultaneously having multiple protrusions 3 on the bracket body 1 engage with the connecting aluminum busbar 4, the connecting aluminum busbar 4 is positioned, thus restricting its rotation or movement. This compensates for slippage defects during the production process and improves the yield of laser welding. Above the battery cell bracket, the protrusions 3 on the bracket body 1 can position the aluminum busbar, preventing misalignment and avoiding "sparking." Furthermore, the absence of welding fixtures improves welding efficiency and quality, thereby solving the problem that existing circular battery cell brackets have a flat surface and lack a positioning structure between the bracket and the aluminum busbar.

[0020] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
