[0030] The present application discloses a driving structure of an embodiment, which can be applied to switch products, such as multi-position switches, one-opening three-hole sockets, one-opening five-hole sockets, etc. The driving structure according to the present application can drive a one-time transmission structure of a large-angle swinging member with a small-angle key, and can also realize a relatively compact switch structure.

[0031] See also Figure 1 , which is a schematic diagram of a three-dimensional structure of a drive structure for a switch. Figure 1 As shown, the driving structure 1 includes at least one seesaw 10 and at least one swinging member 14, each swinging member 14 is adapted to one seesaw 10. The seesaw 10 is pivotally arranged on a pressure plate. The bottom of the pressure plate is also provided with an electrical function module of a switch, such as Figure 1 The wiring terminal module D shown in the figure is usually arranged at a corresponding position of the base of the switch, such as in a predetermined accommodation chamber, to realize the disconnection and connection functions of the switch circuit. Figure 1 As shown, the rocker 10 is provided with a body 11 and an extension plate 12, the extension plate 12 is provided on a single side of the body 11 facing the pressure plate and extends outward, and a guide portion 13 is provided on the extension plate 12. Preferably, the extension plate 12 and the body 11 are perpendicular to each other to further realize the compactness of the switch structure.

[0032] Further reading Figure 1 One end of the swing member 14 is pivotally connected to the guide portion 13, and the other end of the swing member 14 is drivingly connected to a contact bridge of a moving contact piece D1 in the wiring terminal module D. A moving contact is provided on the moving contact piece D1.

[0033] When the seesaw 10 is driven to pivot, the swinging member 14 can swing within a predetermined range, so that the swinging member 14 switches between a first driving position P1 and a second driving position P2, thereby driving the moving contact to connect with different stationary contacts S in the terminal module D to connect or disconnect the switch circuit. According to the above design, through the cooperative driving relationship between the seesaw, the swinging member and the moving contact piece, a one-time transmission structure in which a small-angle button drives a large-angle swinging member is realized, which effectively reduces the overall thickness of the switch and achieves a simplified and compact switch product structure.

[0034] In order to facilitate the installation of related components, such as Figure 2 As shown, the main body 11 is provided with an assembly portion 110 in the middle position, and a first pressing portion 111 and a second pressing portion 112 are respectively located on both sides of the assembly portion 110, a rocker shaft 110A is provided at the connection between the assembly portion 110 and the pressure plate, and the first pressing portion 111 and the second pressing portion 112 are respectively provided with a clamping hole 113, and the clamping hole 113 is used to clamp and cooperate with the key claw arranged on the inner wall of the key to achieve a better driving effect of the switch.

[0035] Considering that the switch needs to satisfy a certain limiting function to ensure the stability of the structure, in order to achieve a better limiting effect, as an optional embodiment, the guide portion 13 is a guide groove 131 provided on the extension plate 12 .

[0036] In order to achieve a compact switch structure and stable limit and transmission effects, such as Figure 3 and 4 As shown, according to a driving structure of an optional embodiment of the present application, the swing member 14 includes a main body support 140, a first swing shaft 141, a second swing shaft 142 and an elastic driving part 143.

[0037] A hollow chamber is disposed inside the main frame 140 , and the chamber is used to accommodate the elastic driving part 143 .

[0038] The first swing shaft 141 is disposed on a first side surface of the main frame 140 , and the first swing shaft 141 extends toward the extension plate 12 and is embedded in the guide groove 131 . In this embodiment, the first side surface is the side surface of the main frame 140 facing the extension plate 12 .

[0039] In order to stably realize the pivoting of the swinging member and the rocker, the shapes and contours of the first swinging shaft 141 and the guide groove 131 are adapted to each other.

[0040] In order to more effectively drive the moving contact piece to swing, Figure 3 As shown, the first swing shaft 141 includes a shaft portion 141A and two force-bearing portions 141B, the two force-bearing portions 141B are symmetrically arranged on both sides of the shaft portion 141A, and are smoothly connected to the shaft portion 141A, and the diameter of the shaft portion 141A is smaller than the width of the guide groove 131. The force-bearing portion 141B is an arc-shaped body, and its tail is a force-bearing surface. In this embodiment, since the force-bearing surface of the swinging member is arranged below the swinging member shaft, the swinging angle of the seesaw with the seesaw shaft as the central axis can be effectively increased, thereby more effectively realizing the driving of the moving contact piece by effectively increasing the stroke of the swinging member.

[0041] The second swing shaft 142 is disposed on a second side surface of the main frame 140. In this embodiment, the second side surface is a side surface of the main frame 140 that is away from the extension plate 12.

[0042] The elastic driving portion 143 is accommodated in the cavity of the main frame 140 , and a sliding member disposed at the bottom thereof elastically abuts against the contact bridge of the movable contact piece D1 .

[0043] In this embodiment, in order to achieve the stability of the seesaw and the swinging member driving the moving contact piece to ensure the reliability of electrical disconnection and connection, the pivot center axis of the first swing shaft 141 and the pivot center axis of the second swing shaft 142 always remain coaxial, the swing center axis of the first swing shaft 141, the swing center axis of the seesaw shaft 110A and the swing center axis of the moving contact piece D1 are the same, the pivot center axis of the first swing shaft 141 is perpendicular to the swing center axis of the first swing shaft 141, and the pivot center axis of the first swing shaft 141 is parallel to the pivot center axis of the seesaw shaft 110A.

[0044] In order to realize the matching relationship between the seesaw, the swinging member and the pressing plate, the pressing plate in this embodiment is provided with a first receiving groove, a second receiving groove, a first extension piece and a second extension piece, the first receiving groove is used to accommodate the extension plate 12 and the first swinging shaft 141, the second receiving groove is used to accommodate the supporting wing 140A of the main frame 140, the first receiving groove is provided with a through hole corresponding to the shaft portion 141A, the second receiving groove is provided with a through hole corresponding to the second swinging shaft 142, the first extension piece and the second extension piece are relatively arranged at the middle position of the pressing plate, and the first extension piece and the second extension piece are both provided with a through hole corresponding to the seesaw shaft 110A of the assembly portion 110. The assembly between the seesaw, the swinging member and the pressing plate is realized by inserting the shaft portion 141A, the second swinging shaft 142 and the seesaw shaft 110A of the assembly portion 110 into the corresponding through holes respectively.

[0045] In order not to hinder the swing of the first swing shaft, the height of the first swing shaft 141 is smaller than the height of the first receiving groove.

[0046] At the same time, the present application also provides a switch having the above-mentioned driving structure, such as Figure 5 As shown, the switch 2 includes a base 30, at least one button 40, at least one wiring terminal module D and at least one of the above-mentioned driving structures 1. Specifically, the base 30 has a receiving cavity and is equipped with a pressing plate 20.

[0047] As an illustrative embodiment, the switch further includes at least one button 40 and at least one wiring terminal module D. The button 40 is used to accept pressing actions in two directions. The wiring terminal module D is connected in the accommodating chamber. It can be understood by those skilled in the art that the number of buttons 30 and wiring module terminals D is not limited. For example, the switch can be a single-button switch, a double-button switch, or a control switch with three or more buttons, but the adjustments and modifications of these design solutions are within the protection scope of the present invention.

[0048] The seesaw 10 is connected to the inner wall of the button 30 through the body 11. In order to achieve a better driving effect of the switch, a button buckle is arranged on the inner wall of the button 40, and the button buckle corresponds to the clamping hole 113 arranged on the seesaw 10 one by one.

[0049] In this embodiment, the seesaw 10 is driven to move by applying pressing actions in different directions to the button 30, thereby driving the swing member 14 to swing within a predetermined range, and the swinging of the swing member 14 drives the moving contact piece to swing, so that the swing member 14 switches between the first driving position P1 and the second driving position P2, thereby driving the moving contact to contact different static contacts S to realize the connection or disconnection of the switch circuit.

[0050] by Figure 1As shown in the figure, the driving principle of the technical solution of the present application is briefly described. In actual operation, the user applies a certain pressing force to one side of the button 30, so that the button 30 will correspondingly drive the seesaw 10 to move toward one side. Since there is a matching relationship between the swinging member 14 and the seesaw 10, the seesaw 10 will drive the swinging member 14 to swing within a certain range, that is, the seesaw 10 swings around its rotation axis after being pressed, and then the inner wall of the guide groove 131 of the seesaw 10 gives a driving force to the force-bearing surface of the swinging member 14 that is in contact with it to move toward the second driving position P2. At this time, the elastic driving part 143 at the bottom of the swinging member 14 is The elastic driving part 143 is compressed and deformed, and driven by the driving force, the elastic driving part 143 is displaced on the contact bridge of the moving contact piece D1 toward the second driving position P2. When it passes the midpoint of the contact bridge, the driving force disappears, the elastic driving part 143 returns to its original shape, and the moving contact piece D1 flips over to contact with a stationary contact S. On the contrary, when the elastic driving part 143 is displaced on the contact bridge of the moving contact piece D1 toward the first driving position P1, when it passes the midpoint of the contact bridge, the moving contact piece D1 flips over to contact with another stationary contact S, thereby flexibly realizing the on-demand switching of the switch circuit between on and off.

[0051] It is worth pointing out that, through the above-mentioned design, the swing angle of the seesaw 10 of the present application is smaller than the swing angle of the swing member 14. Since the button 30 is clamped on the seesaw 10, a larger swing range of the swing member 14 can be achieved with a smaller driving angle relative to the button 30, thereby accurately controlling the contact or disconnection between the moving and static contacts in the terminal module, thereby better realizing the connection or disconnection of the switch circuit.

[0052] To sum up, the above-mentioned scheme of the present application can realize the use of a one-time driving structure to drive a large-angle swinging part with a small-angle button, thereby achieving the reliability of connecting or disconnecting the switch circuit. On the basis of ensuring the stability of the internal electrical functions of the switch product, it cleverly realizes the structural simplification and compact design, optimizes the problems existing in the existing design, and has wide applicability.
