Description

Technical Field

[0001] This utility model relates to the field of battery cell arrangement support technology, specifically an integrated battery cell arrangement support. Background Technology

[0002] A cell arrangement bracket is a support structure used inside a battery module, typically made of metal or engineering plastic. Its main function is to fix multiple cells (such as cylindrical, prismatic, or pouch cells) together in a specific arrangement to achieve efficient space utilization, heat dissipation management, and electrical connection.

[0003] To increase the utilization efficiency of the internal space of the battery pack, the cells are usually arranged relatively tightly. During use, the heat generated by the cells is difficult to dissipate due to the overly precise arrangement, causing the internal temperature to rise continuously, which poses a certain safety risk. Secondly, the connection between cells often uses exposed metal terminals or wires for series connection. Exposed wires or metal terminals are prone to short circuits and arc leakage risks. Utility Model Content

[0004] The purpose of this invention is to provide an integrated battery cell arrangement bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a bottom bracket and an end bracket, both of which have mounting slots that correspond one-to-one. Heat sinks are fixed on both sides of the bottom bracket, and heat-conducting plates are fixed between the heat sinks. Fins are fixed to the outer side of the heat sinks. A wire rack is fixed at the upper end of the end bracket, located between adjacent mounting slots. A wire rack has a wire groove. A cover plate is provided at the upper end of the end bracket. An adapter groove is provided at the bottom of the cover plate, corresponding to the position of the wire rack. The bottom bracket, end bracket, and cover plate are locked together by countersunk bolts.

[0006] Preferably, the bottom support is fixed with a fixing post at each of the four corners, and the upper end of the fixing post is fixed with an internal threaded sleeve. The end support is fixed with a sleeve at each of the four corners, and the upper end of the sleeve passes through the end support. The cover plate has countersunk grooves at each of the four corners. The upper end of the internal threaded sleeve is inserted into the sleeve. The bottom thread of the countersunk bolt is threaded into the internal threaded sleeve, and the upper end of the countersunk bolt is located in the countersunk groove.

[0007] Preferably, a baffle is slidably connected to the upper end of the cover plate at a position corresponding to the countersunk groove, and the end of the baffle extends into the opening of the countersunk groove.

[0008] Preferably, the cover plate has a telescopic groove at its upper end and corresponding to the baffle, the baffle is slidably connected to the telescopic groove at the middle of its bottom, and a telescopic spring is fixed between the baffle and the side wall of the telescopic groove.

[0009] Preferably, the mounting slots are arranged in rows on the bottom support and the end support, and a heat-conducting plate is provided between adjacent horizontal rows of mounting slots, with the mounting slots on adjacent horizontal rows being staggered.

[0010] Preferably, the bottom of the cover plate is provided with protrusions on both sides, and the upper end of the heat sink is engaged between the protrusions and the outer side of the end bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting heat-conducting plates between the wiring brackets, the heat between the battery cells can be transferred to the heat sink and fins on the outside, which can better dissipate heat and avoid the safety risks caused by the difficulty in dissipating heat between the battery cells.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a technical solution: including a bottom bracket 1 and an end bracket 2, both the bottom bracket 1 and the end bracket 2 are provided with mounting grooves 3, and the mounting grooves 3 correspond one to one. Heat sinks 41 are fixed on both sides of the bottom bracket 1, and heat conduction plates 4 are fixed between the heat sinks 41. Fins 42 are fixed on the outside of the heat sinks 41. A wire rack 22 is fixed at the upper end of the end bracket 2 and located between adjacent mounting grooves 3. A wire rack 22 is provided on the wire rack 22. A cover plate 5 is provided at the upper end of the end bracket 2. An adapter groove 51 is provided at the bottom of the cover plate 5 and at a position corresponding to the wire rack 22. The bottom bracket 1, the end bracket 2 and the cover plate 5 are locked and fixed together by countersunk bolts 6.

[0020] The mounting slots 3 are arranged in rows on the bottom bracket 1 and the end bracket 2. A heat-conducting plate 4 is provided between adjacent horizontal rows of mounting slots 3. The mounting slots 3 on adjacent horizontal rows are staggered. The bottom sides of the cover plate 5 are provided with protrusions. The upper end of the heat sink 41 is engaged between the protrusion and the outer side of the end bracket 2.

[0021] The bottom support 1 has four fixed posts 11 at the top corners, and the upper end of the fixed posts 11 is fixed with an internal threaded sleeve 12. The end support 2 has four fixed sleeves 21 at the top corners, and the upper end of the sleeves 21 passes through the end support 2. The cover plate 5 has countersunk grooves 52 at the four corners. The upper end of the internal threaded sleeve 12 is inserted into the sleeve 21. The bottom of the countersunk bolt 6 is threaded into the internal threaded sleeve 12, and the upper end of the countersunk bolt 6 is located in the countersunk groove 52. The cover plate 5 has a baffle 53 at the top and corresponding position to the countersunk groove 52. The end of the baffle 53 extends into the opening of the countersunk groove 52. The cover plate 5 has a telescopic groove at the top and corresponding position to the baffle 53. The bottom middle position of the baffle 53 is slidably connected in the telescopic groove, and a telescopic spring 54 is fixed between the baffle 53 and the side wall of the telescopic groove.

[0022] Working principle: First, lay the bottom bracket 1 flat on the platform, insert the bottom of the battery cell into the mounting slot 3 of the bottom bracket 1, and then load the end bracket 2. During this process, the upper end of the internal threaded sleeve 12 is inserted into the sleeve 21 for positioning to ensure accurate installation. Then, the battery cells are connected in series using wiring, and the wiring is placed in the wire rack 22. Finally, the cover plate 5 is placed on top, so that the wire rack 22 is inserted into the adapter slot 51. At the same time, the countersunk bolt 6 is threaded into the internal threaded sleeve 12 to achieve locking and fixation. The protrusions on both sides can limit and fix the upper end of the heat sink 41 to ensure the stability of the installation. In actual use, since the heat conduction plate 4 will be in contact with the surface of the battery cell, the heat generated will be transferred to the heat sink 41 and the fins 42 for heat dissipation, reducing the risk of heat accumulation between the battery cells. Furthermore, the cover plate 5 can effectively cover and hide the wires connecting the battery cells, improving safety. Finally, the end of the baffle 53 extends into the opening of the countersunk groove 52 to prevent the countersunk bolt 6 from loosening, thus improving the stability of the installation.
