Description

Technical Field

[0001] The utility model relates to the field of circuit switches, in particular to a push plate supporting structure of a pure flat reset switch. Background Art

[0002] In modern electronic and electrical equipment, switches play a vital role as key components for controlling the on and off of circuits. With the advancement of technology and the continuous improvement of user needs, the design and function of switches are also constantly evolving and upgrading. Among them, flat wall switches are highly favored by users due to their unique structure, simple and beautiful appearance design, and excellent performance of fast response.

[0003] However, when using the existing flat wall switch, it is necessary to press the connection area or disconnection area of ​​the button to achieve the connection or disconnection of the wall switch. Since the pressing area is fixed, the user needs to apply a certain force when operating, and this force is often not applied vertically, which can easily cause the button to tilt or shake. This unstable pressing experience not only affects the user's feel, but also has an adverse effect on the mechanical structure inside the switch. Long-term use may cause increased wear of the internal parts of the switch and shorten the service life of the switch. Furthermore, if the button is offset or stuck during the pressing process, the switch may not be disconnected or connected in time, affecting the normal operation of the circuit and even causing electrical failures. In addition, frequent operation and mechanical wear will also increase the probability of switch failure, further increasing the cost of maintenance and replacement. The main reason for the above problems is the unreasonableness of the support structure of the button in the design and manufacturing, which is one of the important reasons for the inconvenience of pressing the existing flat wall switch and the unstable movement of the button.

[0004] Therefore, the supporting structure of the existing flat wall switch needs to be further optimized and improved. Utility Model Content

[0005] The utility model aims to provide a push plate supporting structure of a pure flat reset switch.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following scheme: a push plate support structure of a pure flat reset switch, comprising a panel frame, a panel base detachably provided in the center of the panel frame, a push plate capable of being lifted up and down relative to the panel base provided above the panel base, a hinge groove provided in the center of the panel base, a mounting groove capable of exposing the top of the switch drive mechanism penetrating through the central bottom surface of the hinge groove, a support frame assembly hinged in an "X" shape provided in the hinge groove, the top of the support frame assembly being movably connected to the bottom of the upper push plate, the bottom of the support frame assembly being movably connected to the hinge groove, the center of the support frame assembly having a through groove for exposing the switch drive mechanism, a convex block protruding downwards and capable of passing through the through groove to squeeze the top operating end of the switch drive mechanism provided at the bottom of the push plate. By providing a hinge groove in the center of the panel base and providing an "X"-shaped hinged support frame assembly in the hinge groove, the stability of the push plate when it is lifted up and down is ensured. The top of the support frame assembly is movably connected to the bottom of the push plate, and the bottom is movably connected to the hinge groove, ensuring that the push plate moves smoothly during the pressing process. The bottom of the button is equipped with a bump, which squeezes the top operating end of the switch drive mechanism through the through groove, ensuring that the switch drive mechanism can be accurately triggered each time the button is pressed, improving the reliability and accuracy of the switch operation. At the same time, this design not only improves the pressing feel, making it smoother and more comfortable, but also reduces the mechanical wear and shaking of the button.

[0007] As a further solution of the utility model, the support frame assembly includes an outer support frame and an inner support frame that are cross-hinged together, the left and right ends of the upper corner of the outer support frame are respectively hinged to the bottom of the pressing plate, and the left and right ends of the lower corner of the inner support frame are respectively hinged in the hinge groove. The support frame assembly adopts a design in which the outer support frame and the inner support frame are cross-hinged to each other, which improves the strength and durability of the overall structure. This frame structure can effectively disperse the pressing force, reduce local stress concentration, and extend the service life of the switch.

[0008] As a preferred solution of the utility model, the outer support frame and the inner support frame are both flat rectangular frame structures, and are cross-hinged together, and the through groove is arranged in the center of the inner support frame.

[0009] As an optimal solution of the utility model, lower guide grooves are respectively provided on the left and right sides of the lower corner of the outer support frame in the hinge groove, and lower sliding blocks are respectively provided on the left and right side walls of the lower corner of the outer support frame, which can be inserted into the corresponding lower guide grooves and slide back and forth.

[0010] As a preferred solution of the utility model, upper guide grooves are respectively provided on the left and right sides of the upper corner of the inner support frame at the bottom of the press plate, and upper sliding blocks are respectively provided on the left and right side walls of the upper corner of the inner support frame, which can be inserted into the corresponding upper guide grooves and slide back and forth.

[0011] The design of the upper and lower sliders and guide grooves ensures that the support frame assembly and the pressing plate are fixed and guided during the pressing process, preventing the pressing plate from deviating due to improper pressing force direction. This guide design reduces the possibility of misoperation and further improves the stability of operation.

[0012] As a preferred solution of the utility model, rotating shafts are respectively provided on the left and right outer walls at the center of the inner support frame, and shaft holes capable of accommodating the corresponding rotating shafts to be inserted are respectively provided on the left and right inner walls at the center of the outer support frame.

[0013] As a preferred solution of the utility model, a spring sheet is provided in the installation groove, one end of which is anchored on the top of the switch drive mechanism and the other end of which is tilted upward and abuts against the bottom surface of the pressing plate. The spring sheet provides an automatic reset function. When the user releases the pressing plate, the spring sheet will automatically bounce the pressing plate back to its original position, making it convenient for the next operation. This design not only improves the pressing feel, making it smoother and more comfortable, but also reduces the mechanical wear of the pressing plate.

[0014] In summary, the utility model has the following beneficial effects compared with the prior art: the utility model realizes the smooth up and down movement of the press plate by setting a hinge groove in the center of the panel base and adopting an "X"-shaped hinged support frame assembly in the hinge groove. The top of the support frame assembly is movably connected to the bottom of the press plate, and the bottom is movably connected to the hinge groove. This design avoids the problem of tilting and shaking of the press plate caused by insufficient support points or uneven pressing in the traditional support structure. At the same time, the outer support frame and the inner support frame are intersected with each other and connected in an "X"-shaped hinged manner, which not only enhances the strength and durability of the overall structure, but also effectively disperses the pressing force and avoids local stress concentration, thereby significantly extending the service life of the switch. In addition, a convex block is provided at the bottom of the press plate, which squeezes the top operating end of the switch drive mechanism through the through groove to ensure that each press can accurately trigger the switch drive mechanism, greatly enhancing the reliability of the switch operation. In general, the utility model significantly improves the operating stability, durability and user experience of the switch by optimizing the support design, enhancing the structural strength and providing accurate triggering and resetting functions. It effectively solves the problems of inconvenient pressing operation and unstable pressing plate movement caused by unstable supporting structure and lack of feedback mechanism in existing flat wall switches. It not only improves the practicality of the switch, but also takes into account the dual needs of beauty and function, and meets the high standards and high requirements of modern home and office environments for wall switches.
