[0020] Please see Figure 1 and Figure 2 This embodiment provides a spring structure 10, which is a cylindrical structure with an axially through hole. The spring structure 10 includes a first connecting portion 11, a second connecting portion 12, and multiple contact springs 13. The first connecting portion 11 and the second connecting portion 12 are arranged parallel to each other. The multiple contact springs 13 are disposed between the first connecting portion 11 and the second connecting portion 12 and are integrally formed with the first connecting portion 11 and the second connecting portion 12. A gap 14 is provided between two adjacent contact springs 13. Each contact spring 13 includes a first spring segment 131, a second spring segment 132, and a third spring segment 133 integrally formed in sequence. The end of the first spring segment 131 away from the second spring segment 132 is integrally formed with the first connecting portion 11, and the end of the third spring segment 133 away from the second spring segment 132 is integrally formed with the second connecting portion 12. The second bullet segment 132 has a first arc-shaped protrusion 1321 and a second arc-shaped protrusion 1322 on both sides respectively. The peaks of the first arc-shaped protrusion 1321 and the second arc-shaped protrusion 1322 are located on different horizontal planes to form a staggered peak arrangement.

[0021] The working principle and beneficial effects of the reed structure 10 provided in this embodiment are as follows: The spring structure 10 provided in this embodiment comprises a first spring segment 131, a second spring segment 132, and a third spring segment 133, which are fixedly connected in sequence. A first arc-shaped protrusion 1321 and a second arc-shaped protrusion 1322 are respectively provided on both sides of the second spring segment 132. This increases the effective contact area between the spring structure 10 and the pin, reduces the contact resistance between them, and thus effectively reduces losses and improves energy utilization. Furthermore, the peaks of the first arc-shaped protrusion 1321 and the second arc-shaped protrusion 1322 are located on different horizontal planes, forming a staggered peak arrangement. This not only increases the effective contact area between the spring structure 10 and the pin but also saves space occupied by increasing the area, and the structure is simple.

[0022] In one embodiment, see Figure 2 The length L1 of the first spring segment 131 is 1 / 5 of the length of the contact spring 13, the length L2 of the second spring segment 132 is 3 / 5 of the length of the contact spring 13, and the length L3 of the third spring segment 133 is 1 / 5 of the length of the contact spring 13. This arrangement maximizes the area of ​​the contact spring 13.

[0026] In one embodiment, see Figure 2 The second connecting part 12 has a third connecting buckle 121 at one end and a fourth connecting buckle 122 at the other end.

[0027] The first connecting buckle 111 and the second connecting buckle 112 cooperate to achieve a stable connection between the first connecting part 11 and its ends. The third connecting buckle 121 and the fourth connecting buckle 122 cooperate to achieve a stable connection between the second connecting part 12 and its ends. This allows the spring structure 10 to be stably connected after forming a cylindrical structure by rolling. Furthermore, the connection points of the first connecting buckle 111 and the second connecting buckle 112 are located on different axes from the connection points of the third connecting buckle 121 and the fourth connecting buckle 122, which further ensures the stability of the formed cylindrical structure.

[0028] In one embodiment, see Figure 2 The first connecting buckle 111 is an L-shaped first connecting buckle 111 protruding from the end of the first connecting portion 11; the second connecting buckle 112 is an L-shaped second connecting buckle 112 located at the end of the first connecting portion 11; the fourth connecting buckle 122 is an L-shaped fourth connecting buckle 122 protruding from the end of the second connecting portion 12; and the third connecting buckle 121 is an L-shaped third connecting buckle 121 located at the end of the second connecting portion 12. This arrangement of the first connecting buckle 111, second connecting buckle 112, third connecting buckle 121, and fourth connecting buckle 122 results in a simple connection structure and convenient operation.

[0029] In one embodiment, see Figure 2 and Figure 4 The diameter d of the cylindrical structure formed by the spring structure 10 is 3mm to 15mm, and the height h of the cylindrical structure formed by the spring structure 10 is 8mm to 30mm.

In one embodiment, the diameter d of the cylindrical structure formed by the reed structure 10 is 3.6 mm, and the height h of the cylindrical structure formed by the reed structure 10 is 8 mm. In one embodiment, the diameter d of the cylindrical structure formed by the reed structure 10 is 6 mm, and the height h of the cylindrical structure formed by the reed structure 10 is 14 mm.

[0033] In summary, this embodiment provides a spring structure 10, which is a cylindrical structure with an axially through hole. The spring structure 10 includes a first connecting portion 11, a second connecting portion 12, and multiple contact springs 13. The first connecting portion 11 and the second connecting portion 12 are arranged parallel to each other. The multiple contact springs 13 are disposed between the first connecting portion 11 and the second connecting portion 12 and are integrally formed with the first connecting portion 11 and the second connecting portion 12. A gap 14 is provided between two adjacent contact springs 13. Each contact spring 13 includes a first spring segment 131, a second spring segment 132, and a third spring segment 133 integrally formed in sequence.
