Description
Technical Field
[0001] The utility model relates to the field of circuit switches, in particular to a small-angle swing structure of an ultra-thin switch. Background Art
[0002] The structure of a traditional panel switch mainly includes a panel body, a switch button, a lever, a housing, a moving contact and a stationary contact, wiring terminals and fixings. The panel is the part that carries the switch button and the internal driving mechanism, and is connected and fixed to the switch bottom box embedded in the wall. The moving contact is the conductive part that can swing back and forth, while the lever is used to drive the swing of the moving contact. The stationary contact is the fixed conductive part that is connected to the wiring terminal. When the user presses the switch button, the moving contact will contact or separate from the stationary contact, thereby closing or disconnecting the circuit.
[0003] However, in traditional panel switches, since the switch button is directly connected to the lever to drive the moving contact to swing, the button has a large swing angle and requires a large force to operate the switch, which makes the operation more strenuous and prone to button jamming. At the same time, pressing the button will produce a large noise. Due to the large swing angle, when using a panel switch, there needs to be enough space to ensure that the switch button and the lever can swing freely. Therefore, the buttons of traditional panel switches are usually not made into large-sized panels. If the panel size is too large, the operating part will be too thick and protrude too much from the wall, which will cause visual unsightliness.
[0004] Therefore, the swing structure of the existing switch needs to be further optimized and improved. Utility Model Content
[0005] The utility model aims to provide a small-angle swing structure for an ultra-thin switch.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following scheme: a small-angle swing structure of an ultra-thin switch, including a switch button swingably arranged on the top surface of a switch bracket, a switch back seat at the bottom of the switch bracket, a switch fixing part in the switch bracket, a swinging part that can swing left and right is hinged on the switch fixing part, the bottom end of the swinging part extends into the switch back seat, an inverted "U"-shaped toggle fork arm is arranged on the bottom surface of the switch button, the two free ends of the toggle fork arm pass through the switch bracket downward and are clamped on the left and right sides of the swinging part respectively, the bottom end of the swinging part extends downward and slides against the top surface of the moving contact piece assembly swingably installed in the switch back seat, the toggle fork arm can toggle the swinging part to swing left and right with the swing of the switch button, thereby squeezing the moving contact piece assembly to swing left and right so that it is connected or disconnected with the static contact piece assembly arranged on the left and right sides respectively. The action of the toggle fork arm cooperates with the left and right swing of the swinging part to realize the design of small-angle swing, thereby making the switch thinner and the panel size larger.
[0007] As a preferred solution of the utility model, a drive assembly groove is provided on the bottom surface of the switch bracket, the switch fixing piece is detachably embedded in the drive assembly groove, and through grooves that can penetrate the top surface of the switch bracket are respectively provided on the left and right sides of the drive assembly groove, and the two free ends of the toggle fork arm respectively pass through the corresponding through grooves and are clamped on the left and right sides of the swinging piece. The switch fixing piece is detachably embedded in the drive assembly groove, and this design facilitates maintenance and replacement, making the maintenance of the entire switch easier.
[0008] As a further solution of the utility model, abutment portions which can be clamped by the fork arm are provided on the left and right sides of the swinging member near the top.
[0009] As a preferred solution of the utility model, a hinge groove is provided at the bottom of the switch fixing member, the swing member includes a hinge head hinged in the hinge groove and capable of swinging left and right, a downwardly extending rocker rod is provided at the bottom of the hinge head, the abutting portion is respectively arranged on the left and right sides close to the top end of the rocker rod, and the bottom end of the rocker rod slides and abuts against the top surface of the moving contact piece assembly.

The pressing spring can apply appropriate pressure, so that the driving push rod can effectively push the moving contact piece assembly to flip at any time, ensuring stable and reliable triggering and disconnection of the circuit.
[0011] As a preferred solution of the utility model, the abutment part has a semi-arc outer side surface protruding on the left and right sides of the swing rod near the top. The semi-arc outer side surface of the abutment part can cooperate with the retractable driving top rod to allow the entire swing part to continue to have a certain swing space after the fork arm is moved to swing the swing part to one side, effectively ensuring that the moving contact piece assembly swings down and contacts the contact point on the stationary contact piece assembly.
[0012] Through the above scheme, the driving force is transmitted by utilizing the eccentric drop, so that a small-angle swing of the switch button can drive the swing member to swing at a large angle, further improving the flexibility and reliability of the internal mechanism of the switch.
[0013] As a preferred embodiment of the present invention, the driving top rod includes a main rod inserted in the accommodating hole and a bottom rod connected to the bottom end of the main rod, and a top ball is connected to the bottom end of the bottom rod, which slides against the top surface of the moving contact piece assembly.

[0015] In summary, the utility model has the following beneficial effects compared with the prior art: the utility model drives the large-angle swing of the toggle fork arm and the swinging member through the small-angle swing of the switch button, so as to more effectively realize the flipping of the moving contact piece assembly into place, and ensure stable contact or separation with the contact points on the static contact piece assembly. The utility model uses three non-concentric drops to transmit the toggle force, and realizes the effect of driving the swinging member to swing at a large angle with only a small-angle swing. Compared with the traditional large-angle swing panel switch, the utility model realizes the operation of the switch button in a limited space, thereby reducing the space occupied. It can make the panel switch achieve an ultra-thin and compact design effect. The small-angle swing structure of the utility model can make the area of the switch button larger and the sound smaller. At the same time, the design of the retractable driving push rod and the top pressure spring provides appropriate feedback force to ensure stable and reliable triggering and disconnection of the circuit. Reduce the occurrence of misoperation and bring a better user experience to users. BRIEF DESCRIPTION OF THE DRAWINGS

Around the bottom of the switch bracket 1, a mounting frame 9 for fixing to the switch bottom box is detachably connected. The mounting frame 9 is in a rectangular ring shape with screw holes on the four sides. A switch fixing member 6 is provided in the switch bracket 1. A swinging member 7 that can swing left and right is hinged on the switch fixing member 6. A toggle fork arm 11 extending downward and passing through the switch bracket 1 is provided on the bottom surface of the switch button 2.
