Technical Field
[0001] The present invention relates to the technical field of key switches, and in particular to a switch driving device and a small-angle switch. Background Art
[0002] Wall switches are one of the most common electrical products in daily life and work, among which most wall switches adopt a rocker switch structure. The traditional rocker-type wall switch mainly includes: switch housing, key rocker, rocker, metal rocker with contact points and metal terminal with contact points. The key rocker and the rocker are matched by buckling the rocker with the buckle position on the back of the key rocker, so that the movement axis of the rocker remains unchanged and is directional and flipped in the original position. When the user needs to turn on the light, by touching the key rocker, the key rocker presses the rocker to swing 5° directly, and the contact point on the metal rocker is connected or disconnected with the contact point of the metal terminal, so as to realize the connection or disconnection of the switch.
[0003] However, this traditional switch uses the pressing force of the transmission method to drive the metal lifter. This structure requires a large-angle driving stroke to make the switch work. The large-angle driving stroke is not conducive to the miniaturization of the switch, and the large-angle driving stroke will cause the relative movement amplitude between the components to increase, thereby aggravating mechanical wear and affecting the service life of the switch.

[0033] The present invention provides a switch driving device, referring to Figure 1 and Figure 2In the first embodiment, the switch driving device includes: a switch button 1 and a toggle member 2; the switch button 1 includes a main board 11 and a clamp arm base 12, the clamp arm base 12 is installed on the back of the main board 11, and a clamp arm 13 is provided at one end of the clamp arm base 12 away from the main board 11; the toggle member 2 includes a pressing member 22 and a swing cavity 21 for accommodating the clamp arm 13, and a mounting sleeve 23 extending outward is provided in the middle of the swing cavity 21, the pressing member 22 is installed in the mounting sleeve 23, and the front end of the pressing member 22 abuts against the switch paddle 44.
[0034] More specifically, the switch driving device of this embodiment includes a swinging switch pressing plate 1 and a toggle member 2 for driving the switch paddle 44 to swing to both ends. The switch pressing plate 1 includes a main board 11, a clamp arm base 12 is provided on the back of the main board 11, and a pair of clamp arms 13 are provided at the front end of the clamp arm base 12. The pair of clamp arms 13 are inserted into the inner cavity of the toggle member 2 and are connected with the toggle member 2 to drive the toggle member 2 to swing. Preferably, the main board 11, the clamp arm base 12 and the clamp arm 13 are integrally formed.
[0035] The toggle member 2 includes a swing cavity 21, a mounting sleeve 23 is provided at the front end of the swing cavity 21, a part of the mounting sleeve 23 can be arranged in the inner cavity of the swing cavity 21 for clamping by the clamp arm 13, and a pressing member 22 is provided inside the mounting sleeve 23 to abut against the switch paddle 44.
[0036] It can be understood that in the switch driving device of this embodiment, the clamp arm base 12 and the clamp arm 13 on the clamp arm base 12 swing with the main board 11, and the toggle member 2 connected to the clamp arm 13 swings with the swing of the clamp arm 13, and the switch pressing plate 1 and the toggle member 2 have different rotation axes.

The rotation axis O1 of the switch plate 1 is determined according to the rotation connection member (preferably the mounting bracket 14) between the switch plate 1 and the support seat 5, and the rotation axis O2 of the toggle member 2 is determined according to the movable connection member (preferably the movable shaft 24) between the toggle member 2 and the support seat 5.
[0037] In summary, in the switch driving device of this embodiment, when the switch button 1 is pressed, the clamp arm base 12 and the clamp arm 13 on the clamp arm base 12 swing at a small angle along with the switch button 1. After the angle is enlarged, the toggle member 2 is driven to swing greatly, thereby driving the switch paddle 44 to swing to both ends, thereby realizing the conduction or on-off of the switch circuit, which is beneficial to the miniaturization of the switch and improving the service life of the switch.
[0038] In a preferred embodiment, reference Figure 2 A boss 131 is provided at the front end of the clamp arm 13 .
[0039] It can be understood that the clamp arm 13 of this embodiment is inserted into the inner cavity of the toggle member 2, and a pair of bosses 131 are symmetrically arranged at the front end of the clamp arm 13. The arrangement of the bosses 131 can increase the friction between the clamp arm 13 and the clamped object (i.e., the mounting sleeve 23), making the clamping more stable.
[0040] In a preferred embodiment, reference Figure 2 , Figure 4 and Figure 5 The swing cavity 21 includes a receiving portion 211 surrounded by two side plates arranged opposite to each other, and pressure arms 212 are respectively arranged on both sides of the opening of the receiving portion 211; the clamp arm 13 is inserted into the receiving portion 211 and abuts against both sides of the mounting sleeve 23.
[0041] In this embodiment, the swing cavity 21 includes a accommodating portion 211 and pressure arms 212 arranged on both sides of the opening of the accommodating portion 211, the pressure arms 212 correspond to the position of the clamp arm base 12, the clamp arm 13 on the clamp arm base 12 is inserted into the inner cavity of the accommodating portion 211, and abuts against the positions of both sides of the mounting sleeve 23 near the bottom of the inner cavity. Optionally, the opening size of the clamp arm 13 is adapted to the outer diameter of the mounting sleeve 23. This arrangement prevents the swing cavity 21 from falling off, thereby improving the swing stability of the swing cavity 21.
[0042] In a preferred embodiment, reference Figure 2 , Figure 4 and Figure 5 A spring mounting seat 231 is arranged inside the mounting sleeve 23; the pressing member 22 includes a spring 221 and a pressing head 222, one end of the spring 221 is connected to the spring mounting seat 231, and the other end of the spring 221 is sleeved with the pressing head 222.
[0043] For the toggle member 2 of this embodiment, a spring mounting seat 231 of a specific shape is arranged inside the mounting sleeve 23 thereof. The shape of the spring mounting seat 231 may be a "cross" shape or a cylindrical shape.
[0044] The pressing member 22 of the toggle member 2 includes a spring 221 fixedly connected to the spring mounting seat 231, and a pressure head 222 sleeved with the spring 221, and the front end of the pressure head 222 abuts against the middle top surface of the switch paddle 44. The shape of the pressure head 222 is similar to a bullet head, with a streamlined pointed structure at the front end and a truncated cone structure at the rear end. It is understandable that the toggle member 2 of this embodiment, by providing the pressing member 22 with the spring 221 and the pressure head 222, can ensure the stability of the contact with the switch paddle 44, and the pointed part of the pressure head 222 can accurately locate the position of the switch paddle 44 and evenly apply pressure, thereby ensuring the swing stability of the switch paddle 44.
[0045] Furthermore, an anti-slip structure such as a barb or a bump is provided at the connection between the pressure head 222 and the spring 221 (i.e., the circumferential side of the truncated cone structure) to improve the installation stability between the pressure head 222 and the spring 221 and prevent the pressure head 222 from falling off the spring 221.

The switch pressing plate 1 of the switch driving device is swingably connected to the rear cover 3. The front end of the toggle member 2 of the switch driving device (i.e., the pressing member 22) is in contact with the switch paddle 44. When the switch pressing plate 1 is pressed, the toggle member 2 is driven to swing through the clamp arm base 12 and the clamp arm 13 on the clamp arm base 12, thereby driving the switch paddle 44 to swing to both ends, thereby realizing the conduction or on-off of the switch circuit.
[0050] It is understandable that when installing the small-angle switch, the switch wiring device 4 is first installed in the rear cover 3, and then the toggle member 2 and the support seat 5 are assembled into one body and installed in the rear cover 3, and the support seat 5 is pressed on the switch wiring device 4, and finally the switch pressing plate 1 is swung and installed on the rear cover 3. At this time, because the pressing member 22 of the toggle member 2 presses against the inclined surface of the switch tilting piece 44, the toggle member 2 will be subjected to a reaction force, and the reaction force is transmitted to the main board 11 after passing through the swing cavity 21 and the clamp arm base 12 provided with the clamp arm 13, so that the entire switch pressing plate 1 is tilted.

[0052] It can be understood that one end of the support seat 5 is rotatably connected to the switch button 1, and the other end of the support seat 5 is connected to the wiring assembly to position and support the wiring assembly. A accommodating cavity is provided inside the support seat 5, and the toggle member 2 can be completely inserted into the accommodating cavity of the support seat 5 to limit the swing stroke of the toggle member 2, thereby preventing the toggle member 2 from shaking randomly or deviating from the normal operating trajectory, thereby improving the stability of the switch action.
[0053] When the wiring assembly includes a first wiring terminal 41, a second wiring terminal 42 and a common wiring terminal 43, the support seat 5 can be provided with a first support frame corresponding to the first wiring terminal 41, a second support frame corresponding to the second wiring terminal 42 and a third support frame corresponding to the common wiring terminal 43, and a first plug for fixing the first terminal plate is provided on one side of the first support frame, and a second plug for fixing the second terminal plate is provided on one side of the second support frame. Accordingly, the first terminal plate and the second terminal plate are provided with plug holes at positions corresponding to the plugs, so as to achieve stable support for the wiring assembly.
[0054] In a preferred embodiment, reference Figure 4 , Figure 5 , Figure 7 and Figure 8 The movable shafts 24 are symmetrically arranged on both sides of the toggle member 2 , and a slot 51 is arranged inside the support seat 5 at a position corresponding to the movable shaft 24 , and the movable shaft 24 is installed in the slot 51 .
[0055] More specifically, a pair of movable shafts 24 are symmetrically arranged on both sides of the toggle member 2 parallel to its swinging direction. At this time, the center of the connection line of the pair of movable shafts 24 is the rotation axis of the toggle member 2. Correspondingly, a groove 51 of a specific shape is arranged on the inner wall of the accommodating cavity of the support seat 5 corresponding to the position of the movable shaft 24. The shape of the groove 51 can be U-shaped or teardrop-shaped. At this time, after the toggle member 2 is inserted into the accommodating cavity of the support seat 5, the movable shaft 24 cooperates with the groove 51 to achieve flexible swinging of the toggle member 2.
