Technical Field
[0001] This utility model relates to the field of solid-state battery technology, specifically to a connection bracket for solid-state batteries. Background Technology
[0002] The connection bracket for solid-state batteries is a key component used to connect the internal components of solid-state batteries, such as the cells, and to achieve electrical connection between the battery and external circuits.
[0003] A Chinese patent (CN221262620U) discloses a connection bracket for a solid-state battery, comprising: a main body, including a bracket body; and a protective mechanism, including a fixing plate, wherein the fixing plate is mounted on the surface of the bracket body, a mounting bolt is threadedly connected to the surface of the bracket body, a spring is fixedly connected to the surface of the fixing plate, and a protective plate is fixedly connected to the surface of the spring, the protective plate being slidably connected to the surface of the fixing plate. This invention, through the fixing plate, mounting bolts, spring, and fixing post, allows two sets of protective plates to seal the gap area formed between the battery cell and the bracket groove, preventing dust, water, and other contaminants from entering the bracket groove and contaminating the connection area, thus protecting the connection area of the bracket groove and ensuring the reliability of the battery cell connection on the bracket groove.
[0004] The aforementioned solid-state battery connector only provides mechanical support for the battery cell. When the solid-state battery is put into use, heat will inevitably be generated inside. Traditional connectors are often inadequate in dealing with this heat dissipation problem and are unable to effectively cool down the solid-state battery. Utility Model Content
[0005] The purpose of this invention is to provide a connection bracket for solid-state batteries to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection bracket for a solid-state battery, comprising: a lower bracket, a central bracket, and an upper bracket. Each of the lower bracket, central bracket, and upper bracket has a cell placement slot inside. The lower bracket and upper bracket have a T-shaped groove on one side and a T-shaped block on the other side. A hollow thermally conductive pad is provided at the top of the lower bracket between the cell placement slots. Cooling pipes are provided on both sides of the hollow thermally conductive pad. An upper cover plate is provided at the top of the upper bracket. A connecting pipe is provided at the top of the upper cover plate. An inlet pipe is provided at the top of one cooling pipe, and an outlet pipe is provided at the top of the cooling pipe on the other side.
[0007] Furthermore, a battery cell is placed in the battery cell placement slot, and a battery cell placement slot is also provided inside the upper cover plate.
[0008] Furthermore, the hollow thermal pad is made of insulating silicone, and the interior of the hollow thermal pad is connected to the cooling pipes on both sides.
[0009] Furthermore, the outer walls of the hollow thermal pad are attached to the outer walls of the battery cell on both sides.
[0010] Furthermore, the connecting pipe is used for connection between the tops of two adjacent cooling pipes.
[0011] Furthermore, the T-slots are arranged vertically, and there are multiple T-slots, which are arranged at equal intervals on the lower support.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model, through the setting of a lower bracket, an upper bracket, and a cooling pipe, enables the cell to be fixed in the cell placement slot during solid-state battery connection by the cooperation of the lower bracket, the central bracket, and the upper bracket. The combination of multiple lower brackets can be achieved by the cooperation of the T-shaped slot and the T-shaped block on the lower bracket.
[0014] During the use of the connecting bracket, coolant can be circulated into the inlet pipe, enter the cooling pipe, and then enter the hollow thermal pad. Multiple cooling pipes are connected through the connecting pipe, and finally the coolant is discharged through the outlet pipe. By circulating the coolant around the outside of the cell, the cell temperature can be better controlled. When the cell temperature is high, coolant with a lower temperature can be introduced, and when the external environment is low, coolant with a higher temperature can be introduced, ensuring that the solid-state battery cell operates at a suitable temperature. The entire connecting bracket ensures the mechanical support of the battery while also providing a beneficial effect on the temperature management of the cell.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a connection bracket for a solid-state battery, comprising: a lower bracket 1, a central bracket 5, and an upper bracket 12. Each of the lower bracket 1, the central bracket 5, and the upper bracket 12 is provided with a cell placement slot 3. The cell placement slot 3 enables the cell 4 to be accurately positioned and fixed inside the connection bracket, ensuring the stability of the cell 4 during battery operation, preventing the cell 4 from shifting or shaking, and avoiding battery performance degradation or safety hazards caused by changes in the position of the cell 4.
[0023] The lower bracket 1 and the upper bracket 12 are provided with a T-slot 2 on one side and a T-block 11 on the other side. The matching design of the T-slot 2 and the T-block 11 enables rapid and precise assembly of multiple sets of lower brackets 1 and the entire connecting bracket system through a similar structure. This connection method not only improves assembly efficiency but also enhances the overall mechanical strength and stability of the connecting bracket, enabling it to better withstand various external forces that the battery may be subjected to during use.
[0024] A hollow thermally conductive pad 10 is installed at the top of the lower bracket 1 between the cell placement slots 3. Cooling pipes 7 are installed on both sides of the hollow thermally conductive pad 10. A top cover plate 13 is installed at the top of the upper bracket 12, and a connecting pipe 9 is installed at the top of the top of the top cover plate 13. An inlet pipe 6 is installed at the top of the cooling pipe 7 on one side, and an outlet pipe 8 is installed at the top of the cooling pipe 7 on the other side. The hollow thermally conductive pad 10 fills the space between the cell placement slots 3 and is in direct contact with the outer wall of the cell 4. It can quickly conduct away the heat generated by the cell 4, effectively reducing the operating temperature of the cell 4 and preventing the cell 4 from being affected by overheating, thus improving the safety and reliability of the battery. The cooling pipes 7 work in conjunction with the hollow thermally conductive pad 10 to provide a channel for the circulation of coolant. The coolant flows in the cooling pipes 7, which can carry away the heat conducted from the hollow thermally conductive pad 10, further enhancing the heat dissipation effect on the cell 4 and ensuring that the cell 4 operates within a suitable temperature range.
[0025] The design of the inlet pipe 6 and outlet pipe 8 allows the coolant to easily enter and exit the cooling system. By circulating coolant into the inlet pipe 6, the coolant circulates within the system and is then discharged from the outlet pipe 8, forming a complete cooling loop. This allows for adjustment of the coolant temperature and flow rate according to actual needs, achieving precise control of the cell 4 temperature.
[0026] The battery cell 4 is placed in the cell placement slot 3, and the upper cover plate 13 also has a cell placement slot 3 inside. This ensures the reasonable layout of the battery cell 4 in the connecting bracket, so that the battery cell 4 can cooperate closely with other components of the connecting bracket and give full play to the performance of the battery.
[0027] The hollow thermal pad 10 is made of insulating silicone, and its interior is connected to the cooling pipes 7 on both sides. The insulating silicone material of the hollow thermal pad 10 provides excellent insulation, effectively preventing electrical faults such as short circuits between the battery cells 4, thus improving battery safety. Simultaneously, the silicone material also possesses a certain degree of flexibility and elasticity, allowing it to better conform to the outer wall of the battery cell 4 and improve thermal conductivity. The through-hole design enables the coolant to flow smoothly between the hollow thermal pad 10 and the cooling pipes 7, ensuring that the coolant can promptly remove the heat conducted by the hollow thermal pad 10, improving heat dissipation efficiency and ensuring that the battery cell 4 is always at a suitable operating temperature.
[0028] The outer walls of the hollow thermal pad 10 are in close contact with the outer walls of the battery cell 4. This close contact between the hollow thermal pad 10 and the outer walls of the battery cell 4 increases the contact area between them, improves the heat conduction efficiency, and enables the heat generated by the battery cell 4 to be transferred to the cooling system more quickly, effectively reducing the temperature of the battery cell 4.
[0029] The connecting pipe 9 is used to connect the tops of two adjacent cooling pipes 7. The connecting pipe 9 connects adjacent cooling pipes 7, ensuring the continuous flow of coolant throughout the cooling system, so that the coolant can act evenly on each cell 4, ensuring that all cells 4 can be effectively cooled.
[0030] The T-slots 2 are vertically arranged, and there are multiple T-slots 2, which are equidistantly arranged on the lower support 1. The multiple equidistantly arranged T-slots 2 provide more connection positions and methods, enhancing the connection strength and stability between multiple sets of lower supports 1 and the entire connecting support system.
[0031] When connecting solid-state batteries, the lower bracket 1, the central bracket 5 and the upper bracket 12 cooperate to fix the battery cell 4 in the battery cell placement slot 3. The combination of multiple lower brackets 1 can be achieved by the cooperation of the T-shaped slot 2 on the lower bracket 1 and the T-shaped block 11.
[0032] During the use of the connecting bracket, coolant can be circulated into the inlet pipe 6, and then into the cooling pipe 7, and subsequently into the hollow thermal pad 10. Multiple sets of cooling pipes 7 are connected through the connecting pipe 9, and finally the coolant is discharged through the outlet pipe 8. By circulating the coolant around the outside of the cell 4, the temperature of the cell 4 can be better controlled. When the temperature of the cell 4 is high, coolant with a lower temperature can be introduced, and when the external environment is low, coolant with a higher temperature can be introduced, ensuring that the solid-state battery cell 4 operates at a suitable temperature. The entire connecting bracket ensures the mechanical support of the battery while also providing a beneficial effect on the temperature management of the cell 4.
[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
