Description

Technical Field

[0001] The utility model relates to the technical field of panel switches, and particularly relates to a pressing drive mechanism for a flat reset switch. Background Art

[0002] In the electrical field, a switch is a commonly used circuit control component for controlling the on and off of various electrical devices. In the existing design of push-button switches, pressing at a specific position is required to achieve the connection and disconnection of the circuit, so its scope of use is greatly limited. What users expect is to be able to operate the switch more easily.

[0003] Most switches on the market are rocker switches. By pressing different areas on the switch, the on and off effects are achieved. During the use of this switch, whether it is on or off, one end is always upturned, which affects the aesthetics of the switch and is also prone to dirt accumulation and is not easy to clean.

[0004] The panel switch realizes the switching of the switch state by pivoting the panel back and forth between the open position and the closed position. In the existing panel switch, the panel usually directly drives the swing rod to swing, and the swing rod realizes the switching of the switch state through swinging. Therefore, the pivoting angle of the panel is usually large, and the panel switch needs to provide sufficient movement space for the panel drive mechanism. This results in a relatively large overall thickness of the existing panel switch.

[0005] Therefore, the existing pressing drive mechanism for flat reset switches needs to be further improved. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a pressing drive mechanism for a flat reset switch with a simple structure, a relatively small pressing stroke, effectively reducing the overall thickness of the panel. In addition, it has a large pressing range.

[0007] To achieve the above purpose, the utility model adopts the following scheme: A pressing drive mechanism for a flat reset switch, characterized in that: it includes an installation groove provided in a panel mounting bracket, hinge seats are respectively provided on both sides of the installation groove, a lifting drive piece is hinged in the two hinge seats, a pressing drive head is arranged on the outer side of the lifting drive piece, the pressing drive head is arranged on the outer side of the panel mounting bracket, a lifting drive head is arranged on the inner side of the lifting drive piece, and the lifting drive head is connected to the lifting drive mechanism of the flat reset switch.

[0011] As another improvement to the pressing drive mechanism of the flat reset switch of the present utility model, the connecting bump is a T-shaped bump, and the connecting slot hole includes a first slot body arranged at the bottom of the U-shaped bending portion, and a second slot body communicated with the first slot body is arranged on the side wall of the U-shaped bending portion.

[0012] As another improvement to the pressing drive mechanism of the flat reset switch of the present utility model, the lifting drive head includes a Z-shaped bending portion arranged inside the lifting drive sheet, and a plugging portion is arranged at the end of the Z-shaped bending portion.

[0013] As another improvement to the pressing drive mechanism of the flat reset switch of the present utility model, the width of the plugging portion is less than 1 / 2 of the width of the end of the Z-shaped bending portion.

[0014] As another improvement to the pressing drive mechanism of the flat reset switch of the present utility model, rotating shafts are respectively arranged at both ends of the rotating seat, a limiting step is arranged on the hinge seat, and a positioning step is arranged at a position corresponding to the limiting step on the hinge seat.

[0015] As another improvement to the pressing drive mechanism of the flat reset switch of the present utility model, an included angle is formed between the pressing drive head and the lifting drive sheet, and 0° < included angle ≤ 15°.

[0016] In summary, the beneficial effects of the present utility model compared with the prior art are as follows: The structure of the present utility model is simple.

A lever is formed through a rotating seat, so as to effectively amplify the moment of the lifting drive head, thereby realizing a small stroke at the edge and driving a large stroke in the middle, greatly improving the pressing range of the panel.

[0031] In another embodiment of the present utility model, a rotating seat 4 is hinged in the hinge seat 3, and the lifting drive sheet 5 is connected to the rotating seat 4.

[0032] In the present utility model, a plurality of connecting bumps 41 are arranged at intervals on the inner side of the rotating seat 4, and a plurality of connecting columns 42 are arranged on the upper end surface of the rotating seat 4. In one embodiment of the present utility model, there are four connecting bumps 41, which are evenly arranged on the inner side of the rotating seat 4 respectively.
