Description

Technical Field

[0001] The present application relates to the technical field of switches, and in particular to a high-stability toggle structure and a wall switch. Background Art

[0002] Wall switches are electrical devices installed on the wall to control the on and off of circuits. They are commonly found in homes and offices. As people's pursuit of quality of life continues to improve, the aesthetics and operating experience of wall switches are becoming increasingly important. Based on this, small-angle push-button design is the mainstream trend in the research and development of wall switches, which can reduce the thickness of the switch and improve the aesthetics of the product.

[0003] In the related art, a small-angle wall switch includes a base, a panel, a mounting seat, a swinging member and a contact assembly, wherein the mounting seat is connected to the base, the swinging member is hinged to the mounting seat and connected to the panel, the contact assembly is arranged inside the base, and the contact assembly includes a moving contact and a stationary contact. The swinging member includes a connecting plate and a swing arm, wherein the connecting plate is fixedly connected to the panel, a slot for inserting the moving contact is arranged at the lower end of the swing arm, a spring is installed in the inner cavity of the swing arm, and the spring abuts against the moving contact.

[0004] When the small-angle wall switch is used, the panel is pressed to drive the swinging member to swing, and the thrust of the spring bending deformation drives the moving contact piece to swing, so a smaller pressing angle can be achieved. However, in actual use, if the contact points of the moving contact piece and the stationary contact piece are adhered, the thrust of the spring cannot smoothly drive the moving contact piece to swing, and the problem of not being able to switch smoothly may occur.

[0005] To this end, the Chinese patent with announcement number CN218631785U discloses a wall switch with a small-angle button, in which the inner wall of the lower end of the slot of the swing arm is convexly formed with a toggle convex head, and the two toggle convex heads are arranged symmetrically facing each other, so that the lower end of the slot is narrow, and the moving contact piece passes through the narrow mouth of the slot and extends into the slot, and the toggle convex head cooperates with the moving contact piece to push. If the moving contact piece cannot swing smoothly, the toggle convex head will force it to push, thereby compensating for the deficiency that the spring deformation force occasionally cannot push the moving contact piece to swing, ensuring that the moving contact piece is pushed to a predetermined position, and improving the stability of the switch.

[0006] However, the above patent still has the following defects: during the assembly process, the lower end of the slot is narrow, and the moving contact piece is not easy to insert, especially during the automated assembly process, the metal moving contact piece is easy to come into contact with the toggle boss when inserted into the plastic swing arm, causing the swing arm to be damaged, resulting in product scrapping and high assembly difficulty. Summary of the invention

[0007] In order to ensure that the moving contact piece is reliably pushed and easy to assemble, the present application provides a high-stability toggle structure and a wall switch.

[0008] In the first aspect, the present application provides a high-stability toggle structure that adopts the following technical solution:

[0017] By adopting the above technical solution, it is convenient to insert the swing arm into the toggle part and ensure that the toggle part is reliably pushed. If the gap is too small, it is easy to cause inconvenience in assembly; if the gap is too large, it may not be possible to push the toggle wall after the switch is pressed. This gap range is preferred and suitable for the use of various types of switches.

[0018] Optionally, the swing arm is provided with a socket for inserting the moving contact piece, and the width of the socket gradually increases in a direction approaching the moving contact piece.

[0020] Optionally, a plug-in portion is provided on a side of the movable contact piece close to the swing arm, and the plug-in portion is inserted into the elastic member.

[0021] By adopting the above technical solution, the end of the elastic member is always aligned with the moving contact piece, thereby improving the stability of the elastic force of the elastic member acting on the moving contact piece, thereby improving the reliability of the moving contact piece being moved.

[0022] Optionally, a bending portion is connected between the toggle portion and the moving contact piece, and the plug-in portion, the moving contact piece, the bending portion and the toggle portion are integrally formed.

[0023] Optionally, the plug-in portion is fixedly connected to the movable contact piece, a connecting portion is connected between the two toggle portions, and the connecting portion is provided with a plug hole for the plug-in portion to pass through.

[0024] Optionally, the plug-in portion is fixedly connected between two toggle portions, and an insertion cavity for inserting the movable contact piece is formed between the two toggle portions.

[0025] By adopting the above technical solutions, the above three solutions can all be applied to the high-stability toggle structure of the present application, and the factory can choose according to actual needs.

[0026] Optionally, the cavity includes a positioning wall, a flared wall, a connecting wall and an opening wall in sequence relative to the two inner side walls in a direction close to the moving contact piece, the spacing between the two flared walls gradually increases in a direction close to the moving contact piece, and the spacing between the two opening walls gradually increases in a direction close to the moving contact piece;

[0027] The bottom wall of the cavity is connected with a shifting block, and the shifting block is used to shift the elastic member to bend in a direction away from the pressing side until it fits the corresponding flared wall.

[0028] By adopting the above technical solution, on the one hand, the lower end opening of the swing arm is large, which is convenient for assembly, and on the other hand, the shift block can stably drive the elastic member to bend and deform in the cavity, ensuring the stability of the elastic member acting on the moving contact piece.

[0029] In the second aspect, the present application provides a wall switch adopting the following technical solution:

[0030] A wall switch comprises a panel, a base, a mounting frame, a static contact piece, a wiring piece and a high-stability toggle structure;

[0065] A shift block 727 is fixedly connected to the middle of the bottom wall of the cavity 721, and the width of the shift block 727 gradually decreases in the direction close to the movable contact piece 6, so that the cross section of the shift block 727 is an isosceles triangle. The shift block 727 is used to shift the elastic member 8 to bend in the direction away from the pressing side until it fits the corresponding flared wall 724, ensuring the stability of the elastic member 8 acting on the movable contact piece 6.

[0066] It should be noted that the "pressing side" referred to in this application refers to the side of the wall switch that is pressed, and is not fixed.

[0067] Reference Figure 5 , Figure 6 A socket 722 for inserting the moving contact piece 6 is provided at one end of the swing arm 72 away from the connecting seat 71. The width of the socket 722 gradually increases in the direction approaching the moving contact piece 6, so that the moving contact piece 6 can be easily inserted into the swing arm 72, thereby facilitating assembly.

In the first embodiment of the present application, the gap is preferably 0.2 mm.

[0071] In the first embodiment of the present application, the toggle member is made of plastic, which has the advantages of low cost, convenient production and assembly, and is not easy to damage the swing arm 72. In other embodiments, the toggle member can also be made of ceramic material, metal material, etc.

[0072] Reference Figure 6 , Figure 8 , Fig. 9 In the embodiment of the present application, the connecting piece 5 and the static contact piece 4 are both connected to a terminal block 15 for connecting with a wire. In other embodiments, the wall switch is intelligent, and the connecting piece 5 and the static contact piece 4 can be directly connected to the circuit board. The base 2 is provided with a swinging groove 21 for the moving contact piece 6 to swing. The swinging groove 21 is V-shaped, which limits the movable position of the moving contact piece 6 to ensure smooth switching.

[0073] Reference Figure 8 Both ends of the base 2 close to the panel 1 are fixedly connected with protrusions 22, and the protrusions 22 abut against the panel 1 to facilitate the swing of the panel 1.

[0074] Reference Fig.10 , Fig.11The panel 1 is fixedly connected with a hinge part 14 and a hook 16 on one side close to the mounting frame 3, and a connecting seat 71 is provided with a connecting hole 711 for the hook 16 to pass through. The panel 1 and the swing member 7 are connected by snapping, and the assembly is convenient. The mounting frame 3 includes a hinge seat 31 for the hinge part 14 to be hinged, and the outer peripheral surface of the hinge seat 31 includes a hinge surface 311, an arc surface 312 and an inclined surface 313. The arc surface 312 is arranged on the side of the hinge seat 31 close to the panel 1, and the hinge surface 311 is arranged on the side of the hinge seat 31 away from the panel 1. The inclined surface 313 is symmetrically connected between the arc surface 312 and the hinge surface 311. The hinge part 14 is provided with a hinge hole 141 for the hinge seat 31 to be inserted, and the inner wall of the hinge hole 141 is in contact with the hinge surface 311. The end of the hinge hole 141 away from the panel 1 is connected with a mounting port 142 for the hinge seat 31 to be inserted, so that the assembly of the panel 1 and the mounting frame 3 is convenient.

[0075] Reference Fig.11 , Fig.12 The mounting frame 3 is provided with a receiving groove 33 for the connecting seat 71 to be inserted and swung, and the swing arm 72 is provided in the middle of the mounting frame 3.

The end of the positioning seat 32 close to the panel 1 is provided with a first chamfered surface 323, and the end of the swing block 73 away from the panel 1 is provided with a second chamfered surface 732. When the swing member 7 is installed in the mounting frame 3 , the first chamfered surface 323 and the second chamfered surface 732 cooperate with each other, so that the positioning seat 32 is bent and deformed, thereby facilitating the insertion of the swing block 73 into the positioning hole 321 .

[0076] The implementation principle of the wall switch of the first embodiment of the present application is:

[0077] The toggle structure combines two modes: elastic toggle and forced toggle. Under normal circumstances, the bending deformation of the elastic member 8 is used to push the movable contact piece 6 to swing, thereby realizing the switch opening and closing; if the movable contact piece 6 cannot swing smoothly, the swing arm 72 gradually approaches one of the toggle walls 92, forcing the toggle part 9 to move, and then forcibly driving the movable contact piece 6 to swing, ensuring that the movable contact piece 6 is pushed to the predetermined position, thereby improving the stability of the switch.

[0078] Embodiment 2:

[0079] The only difference from the first embodiment is that the shapes and installation methods of the toggle portion 9 and the plug-in portion 10 are different.

[0080] Reference Fig.13The plug-in portion 10 is fixedly connected to the side of the moving contact piece 6 close to the swing arm 72. In the second embodiment of the present application, the plug-in portion 10 is sheet-shaped and is integrally formed with the moving contact piece 6; in other embodiments, the plug-in portion 10 can also be other shapes and be connected to the moving contact piece 6 in any manner.

[0081] Reference Fig.13 There are two toggle parts 9, which are respectively located on both sides of the moving contact piece 6. A connecting part 12 is fixedly connected between the two toggle parts 9. The connecting part 12 is penetrated by a plug hole 121 for the plug part 10 to pass through. A groove 91 for inserting the side wall of the end of the swing arm 72 is provided on the side of the toggle part 9 close to the swing arm 72. The inner wall of the end of the groove 91 away from the moving contact piece 6 is a toggle wall 92.

[0082] Embodiment three:

[0083] The only difference from the first embodiment is that the shapes and installation methods of the toggle portion 9 and the plug-in portion 10 are different.

[0084] Reference Fig.14 , Fig.15 The plug-in portion 10 is fixedly connected to the side of the moving contact piece 6 close to the swing arm 72. In the second embodiment of the present application, the plug-in portion 10 is sheet-shaped and is integrally formed with the moving contact piece 6; in other embodiments, the plug-in portion 10 can also be other shapes and be connected to the moving contact piece 6 in any manner.

[0085] Reference Fig.14 , Fig.15 Two toggle parts 9 are provided and are respectively located on both sides of the moving contact piece 6. A groove 91 for inserting the side wall of the end of the swing arm 72 is provided on the side of the toggle part 9 close to the swing arm 72. The inner wall of the end of the groove 91 away from the moving contact piece 6 is a toggle wall 92.

[0086] Reference Fig.14 , Fig.15 A bending portion 11 is formed integrally between the toggle portion 9 and the movable contact piece 6. In the third embodiment of the present application, the toggle portion 9, the movable contact piece 6, the bending portion 11 and the plug-in portion 10 are made of metal and are manufactured by punching and bending processes. In other embodiments, the bending portion 11 can be eliminated, and the toggle portion 9 is made of plastic, ceramic or other materials, and is directly fixedly connected to the movable contact piece 6 in any manner.

[0087] Embodiment 4:

[0088] The only difference from the first embodiment is that the plug-in portion 10 is omitted, the structure of the elastic member 8 is different, and the shape and installation method of the toggle portion 9 are different.

[0089] Reference Fig.16 , Fig.17The toggle parts 9 are provided with two integrally formed parts, and two clamping blocks 17 are integrally formed on both sides of the toggle part 9. The movable contact piece 6 is clamped between the two clamping blocks 17, so that the assembly of the toggle part 9 and the movable contact piece 6 is fast and convenient. A groove 91 for inserting the swing arm 72 is provided in the middle of the two toggle parts 9, and the inner walls at both ends of the groove 91 are both toggle walls 92.

[0090] Reference Fig.16 , Fig.17 The elastic member 8 includes a thrust spring 81 and a slide bar 82. One end of the thrust spring 81 abuts against the inner bottom wall of the cavity 721, and the other end abuts against the slide bar 82. The slide bar 82 is slidably disposed inside the cavity 721 and the end thereof extends out of the cavity 721. The end of the slide bar 82 away from the thrust spring 81 is conical and abuts against the inner bottom wall of the groove 91. The thrust spring 81 applies a thrust to the slide bar 82. The two inner side walls of the cavity 721 are parallel to each other, so that the thrust spring 81 is basically kept straight in the cavity 721.

[0091] When the wall switch is pressed, the swing member 7 swings, the swing arm 72 faces one of the toggle parts 9, and the slide bar 82 pushes the toggle part 9 under the action of the thrust spring 81, so that the movable contact piece 6 swings, and the corresponding contact points contact, completing the switch opening and closing. If the elastic member 8 cannot drive the movable contact piece 6 to swing, the swing arm 72 approaches the toggle wall 92, forcibly driving the toggle part 9 and the movable contact piece 6 to swing together, thereby improving the switch stability.

[0092] Compared with the first to third embodiments, the fourth embodiment has a different way of receiving the swinging force on the movable contact piece 6. The spring does not need to be positioned by the plug-in portion 10, but drives the movable contact piece 6 to swing by pushing the slide bar 82. Therefore, the fourth embodiment has the advantage that during assembly, the elastic member 8 does not need to be aligned with the plug-in portion 10, and the assembly efficiency is higher and more stable and reliable.

[0093] Embodiment five:

[0094] The only difference from the fourth embodiment is that the connection method between the toggle portion 9 and the movable contact piece 6 is different.

[0095] Reference Fig.18 A bending portion 11 is formed integrally between the toggle portion 9 and the movable contact piece 6.
