[0040] A multiple multi-speed rotary switch structure provided in this embodiment includes at least a first rotary unit and a second rotary unit to achieve multiple switch effects, and both the first rotary unit and the second rotary unit can achieve multi-speed rotary switch effects, so that the switch structure has the advantages of multiple rotations and flexible switching of multiple speeds. It is applied to the design of electronic and electrical products, can meet the switching requirements of multiple functions, and effectively reduce the design cost.

[0041] Embodiment 1:

[0042] refer to Figure 1-Figure 3 In this example, a multiple multi-position rotary switch structure is provided, which includes at least a first rotary unit 1 and a second rotary unit 2, that is, a third rotary unit 3 and a fourth rotary unit can be added according to actual needs to realize multiple switch functions, wherein each rotary unit can realize a multi-position switch function by rotation.

[0043] The first rotating unit 1 includes a first fixing member 11, a first circuit board 12, a first trigger member 13 and a first rotating member 14. The first fixing member 11 is used for installing and fixing the first circuit board 12 and for realizing a rotational connection relationship with the first rotating member 14. A circuit area for realizing a circuit connection function is provided on the first circuit board 12. After the first trigger member 13 contacts different circuit areas on the first circuit board 12, the function corresponding to the part of the circuit area can be activated. The first rotating member 14 is used for installing and fixing the first trigger member 13 and driving the first trigger member 13 to rotate based on the first fixing member 11, so that the first trigger member 13 rotates and contacts different circuit areas on the first circuit board 12.

[0044] Specifically, the first circuit board 12 is arranged on the first fixing member 11, the first trigger member 13 is arranged on the first rotating member 14, and the first rotating member 14 is rotatably arranged on the first fixing member 11. With the help of the first rotating member 14 rotating on the first fixing member 11, the first trigger member 13 can rotate with the first rotating member 14. During the rotation process of the first rotating member 14, when it contacts different circuit areas on the first circuit board 12, the function corresponding to the part of the circuit area can be turned on. Therefore, the effect of a multi-speed rotary switch can be achieved.

[0045] In this example, there is no restriction on the specific structure of the first fixed member 11 and the first rotating member 14, and the contact portion between the two can be rotationally connected, that is, the portion where the first fixed member 11 and the first rotating member 14 are connected to each other can preferably adopt a circular design, which is more convenient for realizing the rotational connection relationship. The first circuit board 12 is arranged on the end of the first fixed member 11 facing the first rotating member 14, and the first trigger member 13 is arranged on the end of the first rotating member 14 facing the first fixed member 11, so that the first circuit board 12 and the first trigger member 13 are adjacent and relative to each other, so that the first trigger member 13 can contact different line areas on the first circuit board 12 when rotating.

[0046] The second rotating unit 2 has the same function as the first rotating unit 1, and both can realize a multi-speed switch function by rotating. At the same time, on the basis of the first rotating unit 1, the multiple rotation functions of the switch structure can be superimposed. The second rotating unit 2 is connected to the first fixing member 11. Here, it is only necessary to establish a connection relationship with the second rotating unit 2 with the help of the first fixing member 11, so that the first rotating unit 1 and the second rotating unit 2 present a whole structure. The multi-speed rotation function of the second rotating unit 2 is realized by its own structure, and there is no mutual interference between the multi-speed rotation of the second rotating unit 2 and the first rotating unit 1.

The spring sheet is driven to rotate by the rotation of the first rotating member 14. When the spring sheet rotates to different positions and contacts different contacts on the first circuit board 12, it switches to different functions.

[0050] It can be understood that the spring clip is also connected to a circuit board for cooperating with the first circuit board 12 to realize the multi-gear switching function, that is, the first trigger member 13 can also include a circuit board for connecting to the spring clip, and the circuit board is arranged on the first rotating member 14. Of course, the circuit board can be a structure arranged on the first rotating member 14 and connected to the spring clip. It should be noted that in this example, there is no specific restriction on whether the circuit board belongs to the structure on the first trigger member 13 or the structure on the first rotating member 14, and it can be adjusted according to actual needs.

[0051] In some examples, the first circuit board 12 is set on the first fixing member 11 by means of adhesive or hot melt columns. The use of adhesive or hot melt columns can improve the installation stability of the first circuit board 12, thereby improving the use stability of the switch structure.

[0052] Embodiment three:

[0053] refer to Figure 1-Figure 3 In this example, the second rotating unit 2 includes a second fixing member 21, a second circuit board 22, a second trigger member 23 and a second rotating member 24. With reference to the structure of the first rotating unit 1, it can be understood that the second fixing member 21 is used for installing and fixing the second circuit board 22 and for realizing a rotational connection relationship with the second rotating member 24. A circuit area for realizing a circuit connection function is provided on the second circuit board 22. After the second trigger member 23 contacts different circuit areas on the second circuit board 22, the function corresponding to the part of the circuit area can be turned on. The second rotating member 24 is used for installing and fixing the second trigger member 23, and driving the second trigger member 23 to rotate based on the second fixing member 21, so that the second trigger member 23 rotates and contacts different circuit areas on the second circuit board 22.

[0054] Specifically, the second circuit board 22 is arranged on the second fixing member 21, and the second trigger member 23 is arranged on the second rotating member 24. The second rotating member 24 is rotatably arranged on the second fixing member 21. With the help of the second rotating member 24 rotating on the second fixing member 21, the second trigger member 23 can rotate with the second rotating member 24. During the rotation process of the second rotating member 24, when it contacts different circuit areas on the second circuit board 22, the function corresponding to the part of the circuit area can be turned on. Therefore, the effect of a multi-speed rotary switch can be achieved.

[0055] The second circuit board 22 is arranged on one end of the second fixing member 21 facing the second rotating member 24, and the second trigger member 23 is arranged on one end of the second rotating member 24 facing the second fixing member 21, so that the second circuit board 22 and the second trigger member 23 are adjacent and relative to each other, so that the second trigger member 23 can contact different circuit areas on the second circuit board 22 when rotating.

[0056] The second fixing member 21 is connected to the first fixing member 11 , and the first fixing member 11 provides support and connection for the second fixing member 21 , so that the first rotating unit 1 and the second rotating unit 2 form an integral structure.

[0057] refer to Figure 5 and Figure 6 In some examples, the first fixing member 11 is a hollow cylindrical structure, including two openings arranged opposite to each other, and a first supporting sheet 15 is arranged circumferentially near the opening of the first rotating member 14. The first supporting sheet 15 is arranged from the circumference of the opening toward the center direction of the opening, and the first supporting sheet 15 does not cover the opening. The first circuit board 12 is arranged on the upper surface of the first supporting sheet 15. The first circuit board 12 can be arranged on the upper surface of the first supporting sheet 15 by means of adhesive backing or hot melt column.

[0058] A first hook 16 is provided on the first rotating member 14. After the first hook 16 passes through the opening corresponding to the first supporting piece 15, the first hook 16 is buckled with the lower surface of the first supporting piece 15. This buckling relationship can enable the first hook 16 to rotate under the action of external force, that is, when the first rotating member 14 is under the action of external force, it can rotate relative to the first supporting piece 15 on the first fixing member 11 based on the first hook 16.

[0059] The first trigger member 13 is located between the first rotating member 14 and the first circuit board 12 , and because the first trigger member 13 is arranged on the first rotating member 14 , the first trigger member 13 can rotate with the first rotating member 14 and contact different circuit areas on the first circuit board 12 .

[0060] refer to Figure 5 and Figure 7 In some examples, a first connecting portion 17 is provided on the inner wall of the first fixing member 11, and a second connecting portion 25 for connecting to the first connecting portion 17 is provided on the second fixing member 21. Through the connection and matching relationship between the first connecting portion 17 and the second connecting portion 25, the connection effect between the first fixing member 11 and the second fixing member 21 can be achieved.

[0061] Specifically, the first connecting portion 17 is a slot, and the second connecting portion 25 is a buckle. When assembling the second fixing member 21 and the first fixing member 11, the buckle on the second fixing member 21 is aligned with the slot on the first fixing member 11, so that the buckle is installed in the slot in a aligned manner. This can ensure that the positional relationship between the second fixing member 21 and the first fixing member 11 will not change without the action of external force, thereby ensuring the connection stability between the first fixing member 11 and the second fixing member 21. It can also be understood that when it is necessary to disassemble and repair, the slot can be separated from the buckle by external force, thereby separating the second fixing member 21 from the first fixing member 11.

[0062] In order to realize the connection function between the first rotating unit 1 and the second rotating unit 2, and to make the first rotating unit 1 and the second rotating unit 2 form an integral structure, the first rotating member 14 is designed as a hollow cylindrical structure, and the second fixed member 21 passes through the first rotating member 14 and is connected to the first fixed member 11. That is, in terms of structural composition, the first rotating member 14 is located between the first fixed member 11 and the second fixed member 21.

[0063] It should be noted that, according to actual design requirements, the first fixing member 11 can be located between the second fixing member 21 and the first rotating member 14, that is, the first rotating member 14 rotates based on one end of the first fixing member 11, and the second fixing member 21 is located on an end of the first fixing member 11 away from the first rotating member 14.

[0064] Embodiment 4:

[0066] Specifically, the third rotating unit 3 includes a third fixing member 31, a third circuit board 32, a third trigger member 33 and a third rotating member 34. The third fixing member 31 is used for installing and fixing the third circuit board 32 and for realizing a rotational connection relationship with the third rotating member 34. A circuit area for realizing a circuit connection function is provided on the third circuit board 32. After the third trigger member 33 contacts different circuit areas on the third circuit board 32, the function corresponding to the part of the circuit area can be activated. The third rotating member 34 is used for installing and fixing the third trigger member 33, and driving the third trigger member 33 to rotate based on the third fixing member 31, so that the third trigger member 33 rotates and contacts different circuit areas on the third circuit board 32.

[0067] Specifically, the third circuit board 32 is arranged on the third fixing member 31, the third trigger member 33 is arranged on the third rotating member 34, and the third rotating member 34 is rotatably arranged on the third fixing member 31. With the help of the third rotating member 34 rotating on the third fixing member 31, the third trigger member 33 can rotate with the third rotating member 34. During the rotation process of the third rotating member 34, when it contacts different circuit areas on the third circuit board 32, the function corresponding to the part of the circuit area can be turned on. Therefore, the effect of a multi-speed rotary switch can be achieved.

[0068] The third circuit board 32 is arranged on one end of the third fixing member 31 facing the third rotating member 34, and the third trigger member 33 is arranged on one end of the third rotating member 34 facing the third fixing member 31, so that the third circuit board 32 and the third trigger member 33 are adjacent and relative to each other, so that the third trigger member 33 can contact different circuit areas on the third circuit board 32 when rotating.

[0069] The third fixing member 31 passes through the second rotating member 24, the second fixing member 21 and the first rotating member 14 in sequence and is connected to the first fixing member 11, so that the first rotating unit 1, the second rotating unit 2 and the third rotating unit 3 form an integral structure.

The connection effect between the first fixing member 11 and the third fixing member 31 is achieved through the matching connection relationship between the third connecting portion 18 and the fourth connecting portion 35.
