[0002] Nowadays, with the rapid development of new energy vehicles, the weight and cost requirements of automotive parts are becoming more and more stringent. CCS components are an important part of new energy power battery modules. The traditional temperature sensor component structure fixing method cannot be effectively fixed due to the product process and material thickness limitations of blister packaging. It is necessary to add one or more additional injection molding structural parts. The temperature sensor component is fixed by two connected aluminum bars and the bottom structure. The temperature sensor component is assembled with the temperature sensor component through the rivet column on the injection molding structural part and then hot riveted to achieve fixed connection. For the traditional top cover collection type temperature sensor component fixing structure, the bracket not only uses a lot of materials, but also has high mold costs. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1 A new type of fixing structure of a temperature sensor shown in the figure includes a temperature sensor, which structure includes an aluminum bar 1, a blister isolation plate 3 connected to the aluminum bar, and a temperature sensor assembly. A square groove 7 is formed on the aluminum bar 1, one end of the temperature sensor assembly is embedded in the square groove 7, and a reinforcement plate 5 is provided at the other end.

[0017] By opening a square receiving groove, the NTC can be placed inside it, thereby limiting the temperature sensor and preventing it from rotating; by connecting the rivet column on the protection block with the aluminum bar hot riveting, the temperature sensor is limited from another direction, and finally the temperature sensor is fixed. By eliminating the traditional complex fixed bracket structure, the mold manufacturing is simple, the material consumption is saved, and the overall weight and cost reduction of the component are achieved.

[0018] Specifically, the temperature sensor assembly includes a protection block 2, a flexible circuit board 4, and a temperature sensor located between the protection block and the flexible circuit board. The protection block 2 is located on one side of the square groove and is riveted to the aluminum bar. The flexible circuit board 4 is arranged on the blister isolation plate 3. The protection block limits the temperature sensor in the Y-axis direction. The rivet column on the protection block is assembled with the aluminum bar to limit the position in the Z-axis direction. The X-axis is limited by the square groove of the aluminum bar, thereby effectively fixing the temperature sensor assembly.

[0019] Furthermore, a circular hole is formed on the aluminum bar 1, and the rivet post on the protection block 2 passes through the circular hole and is connected to the aluminum bar, such as Figure 3As shown. Aluminum bar 1 is used to achieve electrical connection between battery cells.

[0020] like Figure 2 As shown, the reinforcing plate 5 is a FR-4 reinforcing plate, which is located on the surface of the temperature sensor and fixed on the flexible circuit board. A thermal pad 6 is provided on the surface of the reinforcing plate 5. The thermal pad is used to conduct the heat of the battery core to the temperature sensor.

[0021] The purpose of the utility model is to provide a new type of fixing structure for a temperature sensor. By eliminating the traditional complex fixing structure, the problem of insufficient design space to meet the feasibility of mass production can be solved. Not only can the material usage be reduced, but the scheme has a simple structure, simple mold making, low cost, and convenient product process processing. At the same time, the new type of fixing structure occupies a small space, creating more structural layout space for new energy power battery modules. By designing this scheme, the weight reduction, cost reduction and reliability improvement of CCS components can be achieved, providing effective support for lightweight, cost saving and reliability research of new energy power battery modules.

[0022] The utility model eliminates the use of a traditional temperature sensor bracket, achieves the purpose of reducing costs and weight, creates more structural design space for new energy power battery modules, and thus plays a key role in the sustainable development of the new energy industry.

[0023] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also fall within the protection scope of the present invention.
