[0002] Existing switches mostly employ a two-stage transmission structure, resulting in a large number of parts. During actual production, variations in the dimensions of each part can affect the product's performance. Furthermore, the large number of parts leads to more connection points and potential failure points, ultimately reducing the switch's reliability.

[0003] Therefore, how to improve the reliability of switches has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a switch to improve the reliability of the switch.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A switch includes a button, a pressure plate, a transition member, a conductive structure, and a bracket. The button is rotatably connected to the pressure plate, the transition member is rotatably connected to the pressure plate, and the transition member is connected to the conductive structure to transfer rotation of the button to the conductive structure. Both the pressure plate and the conductive structure are disposed on the bracket.

[0007] Optionally, in the above-described switch, the rotation axis of the button and the rotation axis of the transition member are different, and the distance from the point of contact between the transition member and the button to the rotation axis of the transition member is less than the distance from the point of contact between the transition member and the button to the rotation axis of the button.

[0008] Optionally, in the above switch, the conductive structure includes a first terminal, a second terminal, and a rocker plate. The first terminal and the second terminal are both disposed on the bracket. One end of the rocker plate is connected to the transition member, and the other end is connected to the first terminal.

[0009] The second terminal is provided with a first contact, and the rocker is provided with a second contact.

[0010] Optionally, in the above-mentioned switch, an elastic reset member is provided between the rocker and the button, the first end of the elastic reset member is connected to the button, and the second end of the elastic reset member is connected to the transition member and the rocker respectively.

[0011] Optionally, in the above-mentioned switch, the transition member is provided with a first slot on the side facing the rocker, and the rocker abuts against the first slot or the rocker is disposed in the first slot.

[0012] Optionally, in the above-mentioned switch, the transition member includes a transition member body, a connecting part, and a rotating shaft part. The connecting part is disposed at one end of the transition member body, and the rotating shaft part is disposed on both sides of the connecting part. The rotating shaft part is provided with a first rotating shaft that rotates with the pressure plate.

[0013] Optionally, in the above-mentioned switch, the button includes a button body, a pressing part, and a connecting ear. The pressing part and the connecting ear are both disposed on the button body. The pressing part cooperates with the connecting part to transmit the rotation of the button to the transition member.

[0014] Optionally, in the above-described switch, the contact part includes a connecting wing plate and a connecting plate, the connecting plate being used to connect two adjacent connecting wing plates, one of the connecting wing plates cooperating with the connecting part, and the elastic reset member being connected to the other connecting wing plate.

[0017] As can be seen from the above scheme, the switch disclosed in this application has a simple structure and fewer parts, which facilitates production and quality control.

[0037] The core of this application is to disclose a switch to improve its reliability.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] like Figure 1 and Figure 2 As shown in the figure, this application discloses a switch, including a button 10, a pressure plate 20, a transition member 30, a conductive structure 40, and a bracket 50. The button 10 is rotatably connected to the pressure plate 20, the transition member 30 is rotatably connected to the pressure plate 20, and the transition member 30 is connected to the conductive structure 40 to transmit the rotation of the button 10 to the conductive structure 40, thereby driving the conductive structure 40 to operate and realize the circuit opening and closing. The pressure plate 20 and the conductive structure 40 are both disposed on the bracket 50, and the button 10 is connected to the bracket 50.

[0040] The switch disclosed in this application has a simple structure and fewer parts, which facilitates manufacturing and quality control. When the button 10 moves, it directly pushes the transition piece 30 to move, and the movement of the transition piece 30 drives the conductive structure 40 to move, thereby realizing the switching on and off of the circuit. This eliminates other transmission parts, reduces the impact of manufacturing errors on product performance, and improves the reliability of the switch. The button 10 and the transition piece 30 are simultaneously assembled onto the pressure plate 20, which ensures the stability of the product's performance during movement and also ensures that the switch will not be affected by the deformation of the bracket 50 during installation, thus preventing product performance failure and further improving the reliability of the switch.

[0041] Furthermore, in order to achieve small-angle movement of button 10, such as Figure 4 , Figure 5 and Figure 10 As shown, the rotation axes of button 10 and transition member 30 are different. The rotation axis of button 10 is axis A shown in the figure, and the rotation axis of transition member 30 is axis B shown in the figure. Figure 5 Both axis A and axis B shown are perpendicular to the plane of the paper. The distance from the point of contact between the transition piece 30 and the button 10 to the axis of rotation of the transition piece 30 is less than the distance from the point of contact between the transition piece 30 and the button 10 to the axis of rotation of the button 10. Figure 5As shown, the distance L1 is smaller than the distance L2. When the button 10 rotates at a small angle, the contact position between the button 10 and the transition member 30 will be displaced, thereby driving the transition member 30 to rotate around its rotation axis at a larger angle. The smaller the rotation angle of the button 10, the smaller the opening size of the button 10 will be, which allows the switch to be made thinner and lighter, enhancing aesthetics while reducing costs.

[0042] Furthermore, such as Figure 2 As shown, the conductive structure 40 includes a first terminal 41, a second terminal 42, and a rocker arm 43. Both the first terminal 41 and the second terminal 42 are mounted on the bracket 50. One end of the rocker arm 43 is connected to the transition member 30, and the other end is connected to the first terminal 41. The second terminal 42 has a first contact, and the rocker arm 43 has a second contact. When the button 10 is moved, the transition member 30 can drive the rocker arm 43 to move, causing the second contact to make or break contact with the first contact, thereby achieving circuit connection and disconnection.

[0043] Furthermore, such as Figure 4 As shown, a resilient reset member 60 is provided between the rocker arm 43 and the button 10. The first end of the resilient reset member 60 is connected to the button 10, and the second end is connected to both the transition member 30 and the rocker arm 43. Specifically, the second end of the resilient reset member 60 passes through the cylindrical mounting hole of the transition member 30 and connects to a protrusion on the rocker arm 43. The resilient reset member 60 ensures stable contact or rapid separation between the first and second contacts.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, the transition piece 30 has a first slot 31 on the side facing the rocker 43. The rocker 43 abuts against the first slot 31 or is positioned in the first slot 31 to prevent the rocker 43 from separating from the transition piece 30. At the same time, the first slot 31 also serves to avoid collisions.

[0045] Furthermore, such as Figure 7 As shown, the transition member 30 includes a main body 301, a connecting part 302, and a rotating shaft 303. The connecting part 302 is located at one end of the main body 301, and the rotating shaft 303 is located on both sides of the connecting part 302. The rotating shaft 303 is provided with a first rotating shaft 3031 that rotatably engages with the pressure plate 20. Figure 3 , Figure 4 and Figure 8 As shown, the pressure plate 20 is provided with a mounting cavity, and the transition piece 30 is installed into the mounting cavity. The mounting cavity is provided with a mounting hole 25, and the first rotating shaft 3031 is rotatably engaged with the mounting hole 25. When the transition piece 30 is assembled onto the pressure plate 20, the main body 301 of the transition piece moves away from the pressure plate 20. Figure 8As shown, a limiting part 23 is provided on the pressure plate 20 to restrict the rotation of the transition member 30. Specifically, the transition member 30 can be connected to the pressure plate 20 by elastic snap-fit, so that the first rotating shaft 3031 can be rotatably engaged with the aforementioned mounting hole.

[0046] Furthermore, such as Figure 6 and Figure 8 As shown, the button 10 includes a button body 11, a pressing part 12, and a connecting ear 13. Both the pressing part 12 and the connecting ear 13 are disposed on the button body 11. The pressing part 12 cooperates with the connecting part 302 to transmit the rotation of the button 10 to the transition member 30. The pressure plate 20 is provided with a second rotating shaft 21 that cooperates with the connecting ear 13. Specifically, there are two symmetrically arranged connecting ears 13, and the two connecting ears 13 are symmetrically arranged relative to the pressing part 12. It should be noted that when the button 10 and the transition member 30 are both installed on the pressure plate 20, the pressing part 12 abuts against the connecting part 302 to transmit the rotation of the button 10 to the conductive structure 40. When the button 10 is pressed down, the pressing part 12 moves, pushing the transition member 30 to move, and the transition member 30 drives the rocker plate 43 to move. The switch disclosed in this application, through the above-described structural design of the button 10, directly pushes the transition member 30 to move when the button 10 is pressed down, eliminating other transmission parts, simplifying the structure, and improving the reliability of the switch. It should be noted that the touch-sensitive part 12 and the button body 11 can be an integral structure or a separate structure.

[0047] Specifically, such as Figure 6 As shown, the pressure-sensitive part 12 includes a connecting wing plate 121 and a connecting plate 122. The connecting plate 122 is used to connect two adjacent connecting wing plates 121. One connecting wing plate 121 cooperates with the connecting part 302, and the elastic reset member 60 is connected to the other connecting wing plate 121. When the button 10 and the transition member 30 are both installed on the pressure plate 20, the rotating shaft part 303 is provided on both sides of the connecting plate 122.

[0048] Furthermore, such as Figure 8 and Figure 9 As shown, one of the pressure plate 20 and the bracket 50 is provided with a buckle 22, and the other is provided with a second slot 51 that mates with the buckle 22. The buckles 22 are located on the upper and lower sides of the pressure plate 20, with two buckles 22 on each side. The bracket 50 has second slots 51 corresponding to the buckles 22, and the pressure plate 20 has arc-shaped grooves 24 on both sides. The bracket 50 has protrusions 52 that mate with the arc-shaped grooves 24. With this design, when the switch is wall-mounted, the pressure plate 20 will not sink with the bracket 50, thus reducing the size of the wall mounting opening, improving installation convenience, and enhancing aesthetics.

[0049] Furthermore, the button 10 is snapped into the bracket 50, and the button 10 is provided with snap-fit ​​parts around its perimeter, while the bracket 50 is provided with third slots around its perimeter that cooperate with the snap-fit ​​parts.

[0050] The switch disclosed in this application operates on the following principle:

[0051] Pressing button 10 causes transition piece 30 to move rocker plate 43, thereby connecting and disconnecting the first terminal 41 and the second terminal 42, thus enabling the circuit to be connected and disconnected. Figure 10 This is a schematic diagram of button 10 and transition piece 30 when the first terminal 41 and the second terminal 42 are disconnected, i.e., the circuit is broken. Figure 12 This is a schematic diagram of the button 10 and the transition piece 30 when the first terminal 41 and the second terminal 42 are connected, i.e., when the circuit is on. Figure 11 This is a schematic diagram showing the positions of the first terminal 41 and the second terminal 42 between the on and off states.

[0052] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0054] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
