Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a temperature sampling structure fixing device for a new energy battery module. Background Technology

[0002] During the use of power batteries, temperature sensing elements are needed to monitor the battery temperature in real time to ensure the safety of the battery during the operation of new energy vehicles.

[0003] Traditional FPC temperature sensor mounting requires the use of temperature-sensing protective components and temperature-sensing brackets, and also requires heat riveting for fixation. This method has a long processing flow and is time-consuming. The traditional FCC temperature sensor mounting method involves pasting the temperature sensing circuit board with the temperature sensing element installed onto the inner wall of the U-shaped temperature-sensing protective component, and then inserting an aluminum bar into the groove of the temperature-sensing protective component. This method can cause scratches and damage to the temperature sensing circuit board pasted on the inner wall of the temperature-sensing protective component. At the same time, due to frequent vibrations during vehicle operation, the temperature-sensing protective component may fall off the aluminum bar, affecting the temperature acquisition work.

[0023] This utility model provides, for example Figure 1-4 The device shown is a temperature-sensing structure fixing device for a new energy battery module. It is applied to an integrated circuit board 1. An aluminum bar 3 is provided on one side of the integrated circuit board 1.

[0024] A temperature-sensing dam 51 is installed inside the insertion hole, and an exposure groove for exposing the temperature-sensing element 4 is provided at the top of the temperature-sensing dam 51.

[0025] Clip 52 is installed on the outer wall of temperature-sensitive dam 51 and is used for the fixed installation of temperature-sensitive dam 51.

[0026] Side plate 53 is provided on the outer wall of temperature-sensitive dam 51 and is used to restrict the movement of temperature-sensitive dam 51.

[0027] One side of the bottom of the temperature sensing circuit board 2 is fixedly connected to the top of the integrated circuit board 1, one side of the top of the temperature sensing circuit board 2 is fixedly connected to the bottom of the temperature sensing dam 51, and the bottom of the temperature sensing element 4 is fixedly connected to one side of the top of the temperature sensing circuit board 2.

[0028] Furthermore, the integrated circuit board 1 is an existing integrated circuit board, which can be an FPC integrated circuit board or an FCC integrated circuit board. The temperature sensing circuit board 2 is an existing small temperature sensing circuit board. The temperature sensing element 4 is set on the top of the temperature sensing circuit board 2 away from the integrated circuit board 1. The through hole of the aluminum bar 3 simultaneously inserts the temperature sensing dam 51 and the buckle 52. The top of the temperature sensing circuit board 2 is bonded and fixed to the bottom of the temperature sensing dam 51, and the temperature sensing element 4 at the top of the temperature sensing circuit board 2 is inserted into the exposed groove of the temperature sensing dam 51. The size of the through hole is adapted to the size of the combination of the temperature sensing dam 51 and the two buckles 52.

[0029] The buckle 52 and the side plate 53 are arranged adjacent to each other. The vertical cross-section of the buckle 52 is S-shaped, and the horizontal cross-section of the side plate 53 is rectangular.

[0030] The horizontal cross-section of the temperature-sensitive dam 51 is square, and the side length of the temperature-sensitive dam 51 is 5-8mm.

[0031] The horizontal cross-section of the insertion hole is square, and the side length of the insertion hole is 4-6mm.

[0032] The shortest straight-line distance between the vertical plate of buckle 52 and the side of temperature-sensitive dam 51 is 1-3mm.

[0033] The buckle 52 has a width of 1.5-5mm.

[0034] Furthermore, two buckles 52 are symmetrically arranged on both sides of the outer wall of the temperature-sensitive dam 51, and two side plates 53 are symmetrically arranged on the other two sides of the outer wall of the temperature-sensitive dam 51. The buckles 52 and side plates 53 are respectively arranged on adjacent sides of the temperature-sensitive dam 51. The hooks at the top of the buckles 52 are arranged opposite each other, and the hooks at the bottom of the buckles 52 are arranged opposite each other. The hooks at the bottom of the buckles 52 are fixedly connected to the outer wall of the temperature-sensitive dam 51. The temperature-sensitive dam 51, buckles 52 and side plates 53 are integrally cast. 2. The straight-line distance between opposite sides of the vertical plates is 11-15mm, with a recommended size of 12mm. The straight-line distance between the opposite ends of the top hooks of the two clips 52 is 12.6-16.6mm, with a recommended size of 13.6mm. The vertical straight-line distance from the bottom of the top hook of the clip 52 to the side plate 53 is 3mm, thus accommodating aluminum bars 3 with a thickness of 1-3mm. The recommended width of the clip 52 is 3mm. The recommended side length of the temperature-sensitive dam 51 is 7mm, and the recommended side length of the insertion hole is 5mm. The horizontal straight-line distance between the vertical plate of the clip 52 and the opposite side of the outer wall of the temperature-sensing dam 51 is 1-3mm, with 1mm recommended. Therefore, when installing the temperature-sensing structure and aluminum bus 3 in FPC and FCC, the temperature-sensing circuit board 2 is pasted to the bottom of the temperature-sensing dam 51, the temperature-sensing element 4 is inserted into the exposed groove, and the symmetrically arranged clips 52 are pressed. The temperature-sensing dam 51 and clips 52 are simultaneously inserted into the through slots. Then, the pressure on the clips 52 is released, and the vertical plate of the clips 52 springs back. The buckle 52 fits snugly against the inner wall of the slot, and the hook at the top of the buckle 52 is located at the top of the aluminum bar 3, thereby restricting the temperature-sensing dam 51 from moving vertically downward within the slot. At the same time, the side plate 53 on the outer wall of the temperature-sensing dam 51 has its top end in contact with the bottom end of the aluminum bar 3, restricting the temperature-sensing dam 51 from moving vertically upward. Through the cooperation of the buckle 52 and the side plate 53, the installation between the temperature-sensing dam 51 and the aluminum bar 3 is achieved. This method simplifies the assembly process, reduces material and processing costs, and facilitates the rapid installation of the temperature sensing structure.
