[0034] Reference Figures 1 to 7 , is a switch device according to an embodiment of the present invention, comprising a mounting frame 100, a button 200 and a support structure 300. The mounting frame 100 is provided with a locking hole 110; the middle of the button 200 is rotatably arranged on one side of the mounting frame 100 and can swing relative to the mounting frame 100; the support structure 300 is installed on the mounting frame 100, and the support structure 300 is provided with a support portion 310, which is opposite to the middle of the button 200 and can abut against the side of the button 200 close to the mounting frame 100.

[0035] By adding the support structure 300, when the mounting frame 100 is locked and installed on the wall, even if the mounting frame 100 is deformed, the support structure 300 can additionally support the button 200, so that the button 200 can better maintain a normal position and swing normally, thereby reducing the impact of the bending and deformation of the mounting frame 100 on the normal function of the switch device.

[0036] Specifically, the mounting frame 100 is provided with a switch module 500 , and the switch module 500 has a transmission member 510 , and the button 200 is connected to the transmission member 510 . When the button 200 swings, the switch module 500 is controlled to be turned on and off by the transmission member 510 .

[0037] In the embodiment, the support structure 300 is a frame, and the support structure 300 is installed on the periphery of the mounting frame 100. The support structure 300 is provided with two support parts 310, and the frame includes two first frame bars 320 arranged side by side, and the two support parts 310 are arranged on the two first frame bars 320 in a one-to-one correspondence. Usually, the switch device is installed on the bottom box of the wall. When the switch device is installed on the bottom box, the middle part is usually suspended and the surrounding parts are in contact with the periphery of the bottom box, that is, the deformation of the periphery of the mounting frame 100 is the smallest. At this time, the support structure 300 is made into a frame, and the support structure 300 is located on the periphery of the mounting frame 100, so that the deformation of the mounting frame 100 will basically not affect the support structure 300, and the support structure 300 can maintain its shape to the greatest extent without deformation, so as to support the position of the button 200 to the greatest extent.

[0038] In the embodiment, the locking hole 110 is opposite to the rotation axis of the button 200, and two locking holes 110 are provided and arranged along the rotation axis of the button 200. With the above structure, the switch device can be more firmly locked to the bottom box of the wall, and the deformation degree of the outer periphery of the mounting frame 100 is reduced.

[0039] It is conceivable that in other embodiments, the number of the locking holes 110 can be other numbers, such as one, three, four or more, and those skilled in the art can make specific configurations according to actual needs.

[0040] Specifically, the switch of the present solution has one button 200. It is understandable that in other embodiments, the number of buttons 200 may be two, three or more.

[0041] In the embodiment, the frame also includes two second frame bars 330 arranged side by side, and the two second frame bars 330 are respectively located on both sides of the rotation axis of the button 200, and the support structure 300 is installed on the periphery of the mounting frame 100 through the second frame bars 330. Since the locking hole 110 is opposite to the rotation axis of the button 200, and different locking holes 110 are arranged along the rotation axis, when the switch device is installed on the bottom box, the deformation degree of the area where the mounting frame 100 is opposite to the rotation axis of the button 200 is the largest, and the deformation degree of the mounting frame 100 in the area away from both sides of the rotation axis gradually decreases. At this time, the second frame bar 330 is assembled and connected with the area with the minimum deformation degree of the mounting frame 100, so that the deformation of the mounting frame 100 has the least influence on the support structure 300.

[0042] Specifically, the second frame bar 330 is provided with a hook, and the outer periphery of the mounting frame 100 is provided with a slot, and the second frame bar 330 cooperates with the slot of the mounting frame 100 through the hook to achieve assembly connection between the two. It is conceivable that the second frame bar 330 can also be assembled and connected with the mounting frame 100 through other structures, for example, the second frame bar 330 is provided with a magnet, and the mounting frame 100 is provided with an iron block, and the magnet and the iron block are magnetically attracted to achieve assembly connection between the second frame bar 330 and the mounting frame 100; or the second frame bar 330 is installed to the outer periphery of the mounting frame 100 by screw locking, etc.

[0043] It is understandable that if the support structure 300 is a component installed within the outer periphery of the mounting frame 100, that is, the support structure 300 is installed in the area of ​​the mounting frame 100 where the deformation degree is relatively large, although it has the ability to suppress the deformation of the key 200 to a certain extent, the ability to suppress the deformation of the key 200 is not obvious enough to suppress the deformation of the key 200 in the case where the mounting frame 100 has a large deformation degree, for example, the mounting frame 100 is locked and connected to the bottom box of the wall by screws penetrated through the locking holes 110, and the screws are tightened. In this case, the deformation of the mounting frame 100 is large, and when it is transmitted to the key 200, it may still cause the key 200 to be greatly deformed, which affects the swing of the key 200 and makes the switch device ineffective.

[0044] Specifically, the first frame strip 320 is also opposite to the rotation axis of the key 200 .

[0045] It is conceivable that, in other embodiments, the frame of the support structure 300 may also be assembled and connected to the mounting frame 100 through other positions, for example, the support structure 300 is assembled and connected to the periphery of the mounting frame 100 through the first frame bar 320, or the support structure 300 is assembled and connected to the periphery of the mounting frame 100 through the first frame bar 320 and the second frame bar 330 at the same time, etc.

[0046] Specifically, the support structure 300 is a square frame, and the first frame bar 320 and the second frame bar 330 are connected end to end. It is understandable that the support structure 300 can also be a frame or strip of other shapes, and the support structure 300 can be installed on the outer periphery of the mounting frame 100.

[0047] In the embodiment, the support portion 310 is a support plate 311, and a protrusion 210 is provided on one side of the button 200 close to the mounting frame 100, and the protrusion 210 abuts against the support plate 311. The protrusion 210 abuts against the support plate 311 to limit the deformation of the button 200, so that the contact area between the button 200 and the support plate 311 can be small, and the normal swing of the button 200 is not affected.

[0048] Specifically, the protrusion 210 is an obtuse protrusion with rounded corners, which can make the protrusion 210 have a higher structural strength. It is conceivable that the protrusion 210 can also be other structures, such as an arc protrusion, a semicircular protrusion, etc., and those skilled in the art can make specific configurations according to actual needs.

[0049] Specifically, a recessed groove 220 is provided on one side of the button 200 close to the mounting frame 100, the raised portion 210 is provided at the bottom of the recessed groove 220, and the support plate 311 is located in the recessed groove 220, so that the switch device as a whole can be made thinner, which is convenient for use in occasions of thin switches.

[0050] In the embodiment, a reinforcing rib 312 is provided on one side of the support plate 311 away from the protrusion 210 , which is beneficial to reinforce the support plate 311 , so that the structural strength of the support plate 311 is better to support and suppress the deformation of the button 200 .

[0051] It is conceivable that the support portion 310 can also be other structures, for example, the support portion 310 is a support block, etc., and those skilled in the art can make specific configurations according to actual needs. It is conceivable that the support structure 300 can also be a U-shaped bar, the middle part of the U-shaped bar is assembled and connected with the outer periphery of the mounting frame 100, and the two support portions 310 are arranged on both sides of the U-shaped bar; or the support structure 300 is an L-shaped bar, a part of the L-shaped bar is assembled and connected with the outer periphery of the mounting frame 100, and the other part of the L-shaped bar is provided with the support portion 310, etc.

[0052] In the embodiment, the switch device further includes a washer 400, a countersunk groove 120 is provided at one end of the locking hole 110, a stopper block 130 is provided on the groove wall of the countersunk groove 120, and the washer 400 is provided at the bottom of the countersunk groove 120, and the stopper block 130 can stop the washer 400 from being separated from the countersunk groove 120. During production, the washer 400 is installed in the countersunk groove 120, and the washer 400 first passes over the stopper block 130 and fits to the bottom wall of the countersunk groove 120. Due to the presence of the stopper block 130, the stopper block 130 and the bottom wall of the countersunk groove 120 respectively limit the movement of the washer 400, so that the washer 400 can be positioned, avoiding the risk of the washer 400 falling off from the countersunk groove 120 when the switch device is transported or placed upside down, thereby improving the user experience.

[0053] Specifically, the mounting frame 100 is made of plastic, the gasket 400 is made of metal, and a plurality of reinforcing ribs are provided on the side of the mounting frame 100 away from the button 200. The plurality of reinforcing ribs are arranged in a mesh shape, so that the overall strength of the mounting frame 100 is higher, and when installed by screw locking, it can withstand a greater installation torque.

[0054] In the embodiment, the distance between the blocking block 130 and the hole axis of the locking hole 110 first decreases and then increases along the depth direction of the countersunk groove 120. The blocking block 130 is similar to forming an undercut on the side wall of the countersunk groove 120, so that when the gasket 400 is installed in the countersunk groove 120, it can first pass over the blocking block 130 and move to the bottom of the countersunk groove 120, and can prevent the gasket 400 from leaving the countersunk groove 120. The structure is simple, and the processing and use are relatively convenient.

[0055] In the embodiment, the countersunk groove 120 is provided with six blocking blocks 130, and all the blocking blocks 130 are arranged at intervals around the hole axis of the locking hole 110. The plurality of blocking blocks 130 can better prevent the gasket 400 from escaping from the countersunk groove 120, and the use effect is better. It is conceivable that the number of blocking blocks 130 in the countersunk groove 120 can also be other numbers, such as one, two, three or more, and those skilled in the art can make specific configurations according to actual needs.

[0056] Specifically, the countersunk groove 120 is a non-circular groove, and the corresponding washer 400 is also a non-circular shape, so that the washer 400 can be fixed in the countersunk groove 120 to reduce wear on the mounting frame 100. Specifically, the countersunk groove 120 can be a groove with a racetrack-shaped cross section or an elliptical groove.
