Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an ultra-thin switch. Background Art

[0002] Ultra-thin switches are generally installed on walls or cabinets. Pressing one end of the button turns it on, and pressing the other end of the button turns it off. As a prior art, Chinese Patent 202222548906.X proposes an ultra-thin button switch, which is provided with a guide assembly, and the guide assembly includes a guide hole provided on the inner side wall of the cavity and a guide shaft provided on the side wall of the linkage member, and the guide shaft is passed through the guide hole. The user presses the button to push the linkage member, and the linkage member moves along the guide hole with the cooperation of the guide hole and the guide shaft. Since the guide hole is arranged to extend obliquely, and the straight line where the maximum aperture of the guide hole is located forms a preset angle with the plane where the base is located, the guide shaft rotates at a small angle and moves laterally during the movement of the linkage member to push the trigger plate to move toward the terminal at one end thereof, so that the trigger plate and the terminal are in contact.

[0003] The structural design allows the linkage member to have sufficient movement distance, so that the key movement stroke is longer, and a small key swing angle can be achieved through the cooperation of the guide component, namely the guide hole and the guide shaft.

[0004] However, in this structure, the guide assembly, i.e., the guide hole and the guide shaft, have a relative movement, which requires the guide hole to have a high limit accuracy; the assembly error affects the smoothness of the switch and easily causes a switch virtual position; and the guide hole and the guide shaft have friction in cooperation, which is prone to wear. Utility Model Content

[0005] The utility model aims at providing an ultra-thin switch to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: an ultra-thin switch, including a button, a base, a linkage member, and an electrical connection component, wherein the base is provided with a cavity with a top opening, the linkage member is arranged in the cavity, the electrical connection component includes a trigger plate and a first wiring terminal and a second wiring terminal respectively arranged at two ends of the trigger plate, the bottom of the linkage member extends out of the cavity and contacts the trigger plate, the button is mounted on the base and movably connected to the base, the base is provided with a connecting frame above the opening, the middle position of the connecting frame is provided with a center column, and the bottom of the button is provided with a connecting A connecting piece, a card slot is provided in the middle position of the connecting piece, and the card slot is rotatably connected to the center column; it also includes a guide component, the guide component includes an arc-shaped guide rail arranged on the two side walls of the cavity, a limit column arranged on the side wall at the middle position of the cavity, a slider arranged on both sides of the bottom of the linkage member and a limit slot arranged in the middle position of the linkage member, the arc-shaped guide rail is extended toward the middle and inclined downward, when the button pushes the linkage member, the slider and the arc-shaped guide rail can slide against each other and the limit column can move in the limit slot, so as to realize the abutment of the trigger plate with the first terminal or the second terminal.

[0007] By adopting the above technical scheme, when in use, the user presses the button, and the button deflects to one side through the rotation cooperation of the center column and the card slot. After the button is deflected, the same side of the linkage part is pressed down, and the slider on the same side of the linkage part slides along the arc guide rail toward the center direction and tilted downward, so that the linkage part deflects to one side, and at the same time, the limit column abuts against its side wall after being displaced in the limit slot, thereby limiting the deflection angle of the linkage part. The deflection of the linkage part causes the trigger plate to deflect, and the trigger plate abuts against another terminal after being deflected and separated from the wiring terminal, thereby realizing the switching function of the button, and the button and the connecting frame are fixedly matched with the center axis through the card slot. It is relatively stable when used, and the assembly accuracy requirements are not high, which reduces the errors that may be caused by assembly. The linkage part is guided by the arc guide rail and the limit slot. Compared with the prior art, not only a small key swing angle is achieved, but also a higher switching smoothness is achieved, and wear is reduced.

[0008] As a further optimization of the utility model, the top end of the abutment block is an arc surface inclined outward and downward, and the shape of the pressing block is semicircular.

[0009] By adopting the above technical solution, the friction between the abutment block and the pressure block is reduced, the wear is reduced, and the smoothness during switching is further improved.

[0010] As a further optimization of the utility model, a groove with an opening facing downward is provided at the bottom of the linkage member, a spring and a buffer push head are provided in the groove, and the lower end of the buffer push head elastically extends out of the groove and abuts against the trigger plate.

[0011] By adopting the above technical solution, the buffer push head replaces the connecting piece to contact the trigger plate, which can well adapt to the distance and pressure changes between the two, provide a certain buffer, reduce the wear between the two, and further improve the smoothness of switching.

[0012] As a further optimization of the present invention, a side wall at the opening of the groove is provided with a raised limiting portion, and a side wall of the buffer push head is provided with a step surface and abuts against the limiting portion.

[0013] With the above technical solution, a limiting portion is provided to prevent the buffer push head from falling out of the groove.

[0014] As a further optimization of the utility model, it also includes a rear shell installed on the base, and the electrical connection component is arranged in the rear shell.

[0015] By adopting the above technical solution, the electrical connection component is fixedly installed at the bottom of the base, the installation structure is more stable and reliable, and the easily disassembled rear shell facilitates the replacement and maintenance of the electrical connection component.

[0016] The beneficial effects of the utility model are as follows: when in use, the user presses the button, and the button deflects toward one side through the rotation cooperation of the center column and the card slot. After the button is deflected, the same side of the linkage part is pressed down, and the slider on the same side of the linkage part slides along the arc guide rail toward the center direction and tilted downward, so that the linkage part deflects to one side, and at the same time, the limit column abuts against its side wall after being displaced in the limit slot, thereby limiting the deflection angle of the linkage part, and the deflection of the linkage part causes the trigger plate to deflect, and the trigger plate abuts against another wiring terminal after being deflected and separated from the wiring terminal, thereby realizing the switching function of the button, and the button and the connecting frame are fixedly matched with the center axis through the card slot. It is relatively stable when used, and the assembly accuracy requirements are not high, which reduces the errors that may be caused by assembly, and the linkage part is guided by the arc guide rail and the limit slot. Compared with the prior art, not only a small key swing angle is achieved, but also a higher switching smoothness is achieved, and wear is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
