Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a smart switch. Background Art

[0002] Smart switches play a vital role in smart home systems. They are one of the bridges connecting users and home environments. The main function of smart switches is to achieve intelligent control of lights or other electrical appliances in the home through network connections. Smart switches have functions such as remote control, timer switch, one-button full shutdown, scene mode, voice control, etc., which improve the convenience and comfort of daily life.

[0003] Existing smart switches are usually installed by screw fixing. However, the screw tightening process will cause the bottom shell to deform, and the deformation of the bottom shell may be transmitted to the circuit board and the electronic switch, causing them to be displaced, thereby affecting the normal triggering of the electronic switch. To avoid this problem, in the prior art, the circuit board carrying weak current is usually fixed on the middle shell. Since the middle shell will not be affected by the deformation of the bottom shell, the deformation of the bottom shell will not affect the circuit board. This solution generally uses two methods to fix the circuit board: the first is to fix the circuit board directly to the middle shell with screws; the second is to fix a guard plate on the lower side of the middle shell, and the circuit board is clamped and fixed between the guard plate and the middle shell. Although these two methods can isolate the impact of the deformation of the bottom shell to a certain extent, their installation and disassembly process is relatively cumbersome and it is difficult to improve assembly efficiency. Summary of the invention

[0004] One object of the present invention is to provide an intelligent switch, wherein during the installation of a circuit board, a first circuit surface abuts against a first shell, and a second circuit surface is abutted and supported by a positioning unit, thereby achieving stable positioning of the circuit board between the first shell and the positioning unit; during operation, when a button is subjected to pressing force, the pressing force is transmitted to the circuit board through the electronic switch, and the displacement of the circuit board in the thickness direction is locked by the upward positioning force provided by the positioning unit, thereby ensuring reliable triggering of the electronic switch.

[0005] Another object of the present invention is to provide an intelligent switch, in which the displacement of the circuit board is firmly locked by the positioning part, and reliable support and positioning of the circuit board can be achieved without the use of screws, which greatly improves the convenience of disassembly and assembly of the circuit board.

[0006] Another object of the present invention is to provide an intelligent switch, wherein the design of the positioning unit protruding from the circuit board ensures the stability of the positioning of the circuit board and sufficient support effect, thereby avoiding unnecessary displacement of the circuit board under the action of pressing force and ensuring that the switch can be successfully triggered.

[0007] Another object of the present invention is to provide an intelligent switch, wherein the rigidity of the first connecting arm is greater than that of the second connecting arm. Since the first connecting arm has a higher rigidity and is not easily deformed, while the second connecting arm has a lower rigidity and is easily deformed, when installing the circuit board, the first connecting end is first inserted between the first positioning unit and the first shell, and then the second connecting end is pressed toward the first shell. The second positioning unit is squeezed by the circuit board and drives the second connecting arm to undergo elastic deformation, and then the circuit board is inserted between the second positioning unit and the first shell to complete the installation of the circuit board. The entire installation process is simple and quick, which is conducive to improving assembly efficiency.

[0008] Another object of the present invention is to provide an intelligent switch, wherein the circuit board carries both the high-voltage circuit and the low-voltage circuit, and there is no need to separately set up a high-voltage circuit board or a partition, thereby avoiding interference between the positioning unit and the partition.

[0009] Another object of the present invention is to provide an intelligent switch, wherein the circuit board and the positioning portion are both arranged in the accommodating groove, so as to avoid interference between the positioning unit and the bottom shell, and also avoid the circuit board and the positioning portion occupying the thickness of the first shell, so that the panel thickness of the intelligent switch can be thinned.

[0010] Another object of the present invention is to provide an intelligent switch, wherein the second connecting arm is abutted by the side wall of the accommodating groove to enhance the deformation resistance of the second connecting arm, so as to prevent the circuit board from being separated from the second positioning portion when the button is pressed; and when the first housing is detached from the bottom shell, the second connecting arm is no longer abutted by the bottom shell, and the low rigidity is restored, which is convenient for the installation and removal of the circuit board. This embodiment enhances the deformation resistance of the second connecting arm through the bottom shell, which not only prevents the circuit board from being separated during use, but also retains the advantage of easy disassembly of the circuit board.

[0011] Another object of the present invention is to provide an intelligent switch, wherein the first guiding inclined surface cooperates with the second guiding inclined surface to facilitate the second positioning portion to be installed in the accommodating groove.

[0012] Another object of the present invention is to provide an intelligent switch, wherein two second positioning portions are located on both sides of a circuit board and are arranged relative to each other, so that the forces on the two second positioning portions with lower rigidity are balanced with each other, thereby accurately locking the position of the circuit board between the two second positioning portions; and avoiding the second positioning portion with lower rigidity being arranged relative to the first positioning portion with higher rigidity, causing the second positioning portion to be squeezed.

[0013] Another object of the present invention is to provide an intelligent switch, wherein the electronic switch is located on the connecting line of two second positioning portions, so that the positioning force provided by the second positioning portions acts more directly on the electronic switch, making the positioning of the electronic switch more stable and preventing the electronic switch from being pressed and displaced.

[0014] Another object of the present invention is to provide an intelligent switch, wherein the first positioning column can improve the positioning accuracy of the circuit board in the horizontal direction, and cooperate with the first positioning portion and the second positioning portion to achieve precise positioning of the circuit board in the horizontal and vertical directions, thereby ensuring that the electronic switch is accurately triggered.

They are only for the convenience of describing the present invention and are not required that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0059] In the description of the present specification, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0060] In the description of the present invention, unless otherwise clearly specified and limited, the term "connection" and other terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The technical solutions between the various embodiments can be combined with each other, but must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0062] Smart switches are generally designed with luminous text or patterns on the button surface, and LED lights and light-homogenizing covers are set inside the panel. The light emitted by the LED lights is homogenized by the light-homogenizing cover and then irradiated to the buttons, making the text or patterns on the button surface glow. Ultra-thin smart switches have a very thin panel, resulting in insufficient homogenization space and poor homogenization effect. When the luminous surface of the button is large, it can be seen that the luminous surface is obviously uneven.

[0063] To solve the above problems, according to the first aspect of the present invention, a light-transmitting structure is provided, which is not only applicable to smart switches, but also applicable to other products with key panels. Figure 1-Figure 26 , the light-transmitting structure provided by the present invention will be specifically explained. Figure 2 , Fig. 9 , Fig.10 and Fig.11 As shown, Fig. 9 for Figure 2 The vertical cross-sectional view of the AA portion, Fig.10 for Fig. 9 The enlarged view of part B, Fig.11 for Fig.10 The cross-sectional view of the CC portion of the embodiment of the present invention is a partial enlarged view. The light-transmitting structure includes a first shell 1, a key 2 and a circuit board 3. The key 2 is arranged on the first side of the first shell 1; the circuit board 3 is arranged on the second side of the first shell 1 opposite to the first side; the first shell 1 is provided with a light source space 111 and a reflection space 112 adjacent to the light source space 111, the key 2 is provided with a light-transmitting area 21 at a relative position to the reflection space 112, a light-guiding channel 113 is provided between the light source space 111 and the reflection space 112, and the circuit board 3 is provided with a light-emitting component 35 inside the light source space 111; the light emitted by the light-emitting component 35 passes through the light-guiding channel 113 to irradiate the reflection space 112, and then passes through the reflection space 112 to the light-transmitting area 21 of the key 2, and finally passes through the light-transmitting area 21. The light-transmitting area 21 can be a through hole or a hollow text or pattern, and the light passes through the light-transmitting area 21 to form a small luminous hole or text or pattern on the outer surface of the key 2.

[0064] In the light-transmitting structure provided by the present invention, the light emitted by the light-emitting component 35 is reflected by the reflection space 112 to the light-transmitting area 21 through the light-guiding channel 113, thereby preventing the light-emitting component 35 from directly irradiating the light-transmitting area 21, and the light produces a uniform light effect during the reflection process. In addition, the expansion of the reflection space 112 in the horizontal direction will not increase the thickness of the first shell 1, so that there is sufficient space for the light to achieve a better uniform light effect, which solves the problem of uneven display of the light-emitting surface of the button 2 of the ultra-thin smart switch 100 due to insufficient uniform light space, and enables large-area light emission of the ultra-thin smart switch 100. The ultra-thin can be understood as: when the smart switch 100 is installed on the wall, the thickness of the components of the smart switch 100 located outside the wall (i.e., the first shell 1 and the button 2) is very thin, so that the smart switch 100 is visually ultra-thin.

[0065] The first side of the first housing 1 is Fig. 9 The upper side of the first shell 1, the second side of the first shell 1 is Fig. 9 The light source space 111 and the reflection space 112 may be spaces arranged inside the first shell 1, or spaces formed by the first shell 1 and other components. The light guide channel 113 may be a channel-shaped structure, or a through hole, a notch, or other structures that allow light to pass through. The light emitting element 35 may be an LED lamp or other electronic components that can emit light.

[0066] Furthermore, the first shell 1 is injection-molded from white plastic, and the inner walls of the light source space 111 and the reflection space 112 are both white to reduce light brightness loss.

[0067] In an exemplary embodiment, the light reflected by the reflection space 112 is irradiated to the light-transmitting area 21, and the light is transmitted through the light-transmitting area 21; in another exemplary embodiment, a light homogenizer (not shown in the figure) is arranged between the reflection space 112 and the light-transmitting area 21, and the light reflected by the reflection space 112 is homogenized by the light homogenizer and irradiated to the light-transmitting area 21, and then transmitted through the light-transmitting area 21 to enhance the light homogenization effect.

[0068] In an exemplary embodiment, the inner wall of the reflection space 112 is constructed as a frosted surface so that the light is diffusely reflected in the reflection space 112, thereby enhancing the uniform light effect; in another exemplary embodiment, the inner wall of the reflection space 112 is constructed as a smooth surface so that the light reflection brightness is higher.

[0069] Furthermore, if Fig.10As shown, the direction of the light source space 111 toward the reflection space 112 is set as a first direction, and the direction of the reflection space 112 toward the light-transmitting area 21 is set as a second direction. In a preferred embodiment, the first direction is perpendicular to the second direction, so that when the light-transmitting area 21 is large, the light emitted by the light-emitting element 35 is prevented from being directly emitted from the light-guiding channel 113 to the light-transmitting area 21; and the light source space 111 and the reflection space 112 are arranged side by side along the first direction, which reduces the stacking of the two in the vertical direction, making the thickness of the first shell 1 thinner. Among them, the first direction and the second direction have been Fig.10 Winning bid.

[0070] In some embodiments, Fig.10 As shown, the reflection space 112 includes a first reflection surface arranged facing the light source space 111, and the first reflection surface is inclined to the first direction. Among them, the first reflection surface is the surface that receives direct light from the light-emitting element 35, and the first reflection surface is inclined to ensure that enough light is reflected to the light-transmitting area 21 to enhance the brightness of the light-transmitting area 21. Furthermore, the angle between the first reflection surface and the first direction is greater than 45°, that is, the first reflection surface is more inclined to the vertical plane, so that the light is reflected multiple times in the reflection space 112 to obtain a better uniform light effect. In an exemplary embodiment, the angle between the first reflection surface and the first direction is 60°.

[0071] Furthermore, if Figure 7 , Fig.10 and Fig.11 As shown, the reflection space 112 is constructed as a trumpet-shaped structure with open upper and lower ends and a larger upper part and a smaller lower part. The circuit board 3 is covered on the lower end of the trumpet-shaped structure; the trumpet-shaped structure includes the first reflection surface, the second reflection surface opposite to the first reflection surface, and the third reflection surface and the fourth reflection surface respectively arranged on both sides of the first reflection surface, the first reflection surface, the third reflection surface, the second reflection surface and the fourth reflection surface are mutually surrounded to form the side wall of the trumpet-shaped structure, and the light guiding channel 113 is opened on the second reflection surface; the direction of the reflection space 112 toward the light-transmitting area 21 is set as the second direction, the first reflection surface, the third reflection surface and the fourth reflection surface are respectively inclined to the second direction, and the inclination angle of the first reflection surface relative to the second direction is greater than the inclination angle of the third reflection surface, and greater than the inclination angle of the fourth reflection surface, so as to ensure that enough light is reflected to the light-transmitting area 21 to enhance the brightness of the light-transmitting area 21. In an exemplary embodiment, the inclination angle of the first reflecting surface relative to the second direction is 30°, the inclination angles of the third reflecting surface and the fourth reflecting surface relative to the second direction are both 25°, and the inclination angle of the second reflecting surface relative to the second direction is 2°.

[0072] Since the light emitting element 35 is a point light source, its light intensity gradually decreases from the center to the periphery. Therefore, when the light is irradiated to the first reflective surface, the brightness at the center of the first reflective surface will be slightly higher than the brightness on both sides thereof, resulting in uneven reflection on the first reflective surface. To solve this problem, in some embodiments, such as Fig.11 , Fig.10 and Figure 7 As shown, the light-guiding channel 113 is provided with a light-blocking portion 114 at a position directly opposite to the light-emitting element 35. The light-blocking portion 114 is used to block a portion of the light emitted from the light-emitting element 35 and entering the reflection space 112, so as to reduce the brightness of the light-emitting element 35 irradiating the center of the first reflection surface, so that the light can be irradiated to the first reflection surface more evenly, thereby achieving a better uniform light effect in the reflection space 112. In addition, during the design, the width and height of the light-blocking portion 114 can be designed to a more appropriate size according to the actual illumination effect, so as to obtain a better uniform light effect. In an exemplary embodiment, as Fig.11 As shown, the bottom of the second reflecting surface abuts against the circuit board 3, and the bottom of the second reflecting surface has a long strip notch, and the long strip notch and the circuit board 3 form the light guiding channel 113; the light blocking portion 114 extends from top to bottom on the second reflecting surface, and the light blocking portion 114 is constructed in a square shape, and there is a light-transmitting gap between the bottom of the light blocking portion 114 and the circuit board 3, and the light blocking intensity can be adjusted by adjusting the height and width of the light blocking portion 114, thereby achieving a better uniform light effect.

[0073] In some embodiments, Fig.10 and Fig.15 As shown, the light source space 111 is formed by the top wall of the light source and the side walls of the light source, and the light guiding channel 113 is opened on the side walls of the light source; the circuit board 3 is covered on the bottom of the light source space 111 to form a light source accommodating cavity between the light source space 111 and the circuit board 3, and the light emitting component 35 is accommodated in the light source accommodating cavity, so as to prevent the light of the light emitting component 35 from directly irradiating the light-transmitting area 21 of the button 2, and to prevent the light of the light emitting component 35 from transmitting through the gap of the first shell 1.

[0074] Furthermore, if Fig.10 and Fig.11 As shown, the surface of the circuit board 3 is white at the position corresponding to the light source accommodating cavity and the position corresponding to the reflecting space 112 to avoid color cast of the light reflected by the circuit board 3. In an exemplary embodiment, the surface of the circuit board 3 is screen-printed with white oil at the position corresponding to the light source accommodating cavity and the position corresponding to the reflecting space 112 to achieve color change. In other embodiments, the color of this position can also be changed by pasting a white film.

[0075] In some embodiments, Figure 2-Figure 6 and Fig.10 As shown, the key 2 includes a key bracket 22 made of plastic and a key panel 23 made of glass. The key bracket 22 is rotatably connected to the first shell 1, and the key panel 23 is pasted on the key bracket 22. The side of the key panel 23 facing the key bracket 22 is covered with a light-shielding layer, and the light-shielding layer is hollowed out to form the light-transmitting area 21. The key bracket 22 is provided with a light-transmitting hole 221 at a position corresponding to the light-transmitting area 21. The light reflected by the reflection space 112 passes through the light-transmitting hole 221 to irradiate the light-shielding layer, and then passes through the light-transmitting area 21. Among them, the rotation connection can be understood as a connection method that can rotate relatively, including a shaft-hole rotation connection, a snap-on rotation connection, etc. The light-shielding layer includes a color layer facing the key panel 23 and a black spray paint layer facing the key bracket 22. The color layer is used to make the key panel 23 present color, and the black spray paint layer is used for light shielding. The light shielding layer is laser engraved to form hollow characters or patterns, which form the light-transmitting area 21. Light passes through the light-transmitting area 21 to form luminous patterns or characters on the key panel 23. The key panel 23 is made of AG frosted glass, which has a slight light-homogenizing effect.

[0076] It is worth mentioning that the buttons of the existing intelligent switches are generally made of plastic material and are integrally injection molded, which has poor rigidity. When the buttons are thin, the deformation of the buttons is large, and it is easy to fail to trigger the electronic switch. The button 2 of this embodiment adopts a structure in which a plastic bracket and a glass panel are matched, so that the button 2 has both the easy processing and shaping ability of the plastic material and the rigidity of the glass, so that the button 2 has a strong anti-deformation ability while meeting the connection function, so that the button 2 can avoid being too thin to easily deform and fail to trigger the electronic switch 31 while being thinned. Among them, the electronic switch 31 can be a micro switch, a touch switch, a membrane switch, etc. In an exemplary embodiment, the electronic switch 31 uses a micro switch 311.

[0077] Furthermore, the light-transmitting hole 221 is configured as a square through hole, and the light-transmitting area 21 is located within the light-transmitting hole 221. Fig.10 and Fig.11 As shown, the size of the light-transmitting hole 221 is slightly larger than the size of the upper opening of the reflection space 112 .

[0078] According to a second aspect of the present invention, Figure 1-Figure 26As shown, there is also provided an intelligent switch 100, comprising the above-mentioned light-transmitting structure, and also comprising a bottom shell 4, wherein the first shell 1 is covered on the bottom shell 4, and the bottom shell 4 is provided with a receiving groove 41, and the circuit board 3 is received in the receiving groove 41. The first shell 1 can be understood as the middle shell of the intelligent switch 100, and when the intelligent switch 100 is installed on a wall, the first shell 1 is located outside the wall, the front of the first shell 1 is covered with the button 2, and the side of the first shell 1 is exposed outside the wall.

[0079] In the embodiment of the present invention, the circuit board 3 is placed in the receiving groove 41 of the bottom shell 4, so that the circuit board 3 does not occupy the space of the first shell 1, making the first shell 1 thinner. In addition, the circuit board 3 is arranged in the receiving groove 41, so that the first shell 1 has enough space to design the above-mentioned light-transmitting structure while being thinned, so as to realize the design of the ultra-thin smart switch 100.

[0080] Furthermore, if Fig.17 and Fig.18 As shown, the circuit board 3 carries weak current circuits and strong current circuits, and the circuit board 3 is provided with a power module (not shown in the figure), a relay 32, a wireless communication module 33, a processing module 34, an electronic switch 31 and the light-emitting element 35. These electronic components are arranged on the same circuit board 3, which can reduce the number of circuit boards 3 and save the space occupied by the circuit board 3, so that the accommodating groove 41 can accommodate the entire circuit part, thereby reducing the panel thickness of the smart switch 100. The panel of the smart switch 100 can be understood as the part located outside the wall when the smart switch 100 is installed on the wall.

[0081] Furthermore, the power module and the relay 32 are arranged on the lower surface of the circuit board 3, and the lower surface of the circuit board 3 is also provided with a wiring terminal 36, and the wiring terminal 36 is used to connect the neutral line, the live line and the control line of the controlled device. The power module is connected to the neutral line and the live line through the wiring terminal 36, and is used to convert the household AC power into low-voltage DC power, so as to supply power to the weak current circuit. The relay 32 is electrically connected to the processing module 34, and the processing module 34 controls the relay 32 to switch the on-off state in response to the triggering of the electronic switch 31. The relay 32 is connected to the controlled device through the wiring terminal 36, and the relay 32 switches the on-off state to cut off or connect the power supply of the controlled device, thereby realizing the switch function.

[0082] Furthermore, if Fig.17 As shown, the processing module 34 is integrated in the wireless communication module 33, and the wireless communication module 33 is arranged on the upper surface of the circuit board 3 to enhance the signal strength of the wireless communication module 33; further, the wireless communication module 33 has a communication antenna 331, and the circuit board 3 has a communication gap 37 at a position corresponding to the communication antenna 331 to prevent the circuit board 3 from generating a shielding effect.

[0083] Furthermore, if Fig.18 As shown, the side wall of the accommodating groove 41 is provided with an escape groove 46 at a position corresponding to the wireless communication module 33 , and the escape groove 46 is used to make an escape space for the wireless communication module 33 to avoid interference between the wireless communication module 33 and the bottom shell 4 .

[0084] In the existing smart switches with key lighting function, the gaps between the keys and the gaps between the keys and the middle shell are prone to light leakage, especially in ultra-thin smart switches. Since the keys and the middle shell are thin, there is not enough space to design a light-shielding structure, which makes it very easy to leak light.

[0085] To solve the problem of light leakage of the intelligent switch, in some embodiments, Figure 3 , Figure 7 , Fig.10 as well as Fig.11 As shown, the first shell 1 is provided with a light transmitting structure 11, and the button 2 is provided with the light-transmitting area 21 at a position relative to the light transmitting structure 11. The light emitted by the light-emitting component 35 is transmitted to the light-transmitting area 21 of the button 2 through the light transmitting structure 11, and then passes through the light-transmitting area 21; the button 2 is provided with a light-shielding portion 223 protruding toward the first shell 1, and the light-shielding portion 223 surrounds at least two sides of the light-transmitting area 21. The first side of the first shell 1 is provided with a first recess 121, and the light-shielding portion 223 is at least partially sunken into the first recess 121.

[0086] By staggered cooperation of the light shielding portion 223 and the first recess 121 in the vertical direction, light cannot be transmitted from the side of the key 2, thereby avoiding light leakage. The light shielding portion 223 may be a structure such as a light shielding rib, a light shielding plate, etc., and the light shielding portion 223 at least partially sinking into the first recess 121 can be understood as the light shielding portion 223 and the first recess 121 overlapping in the thickness direction, thereby preventing light from being transmitted from the gap between the light shielding portion 223 and the first recess 121.

[0087] The light transmission structure 11 includes the light source space 111, the reflection space 112 and the light guide channel 113 mentioned above, and the light emitting element 35 is arranged in the light source space 111. The transmission includes light propagation modes such as direct emission and reflection. The technical details of the light source space 111, the reflection space 112, the light guide channel 113, the light-transmitting area 21 and the light emitting element 35 have been described in detail above and will not be repeated here.

[0088] In addition, since the circuit board 3 is accommodated in the accommodating groove 41 of the bottom shell 4 , the circuit board 3 does not occupy the space of the first shell 1 , so that the first shell 1 can have enough space to set the first recess 121 .

[0089] When the smart switch 100 is a multi-key smart switch 100, the key 2 includes a plurality of key units 20, and the electronic switches 31 are arranged one by one with the key units 20. Each key unit 20 can be pressed to trigger the corresponding electronic switch 31. There is a second split slit 272 between each key unit 20, and the second split slit 272 is the main part of the key 2 that leaks light. In order to avoid light leakage from the second split slit 272, in the embodiment of the present invention, Figure 3 , Figure 7 as well as Fig.11 As shown, a second recess 122 is provided on the first side of the first shell 1 in the area corresponding to the first boss 13, and the height of the light-shielding portion 223 at the corresponding position of the second recess 122 is higher than the height of the light-shielding portion 223 at other positions, and the light-shielding portion 223 close to the second dividing seam 272 is located in the second recess 122, so that the light-shielding portions 223 on both sides of the second dividing seam 272 can be embedded deeper in the first shell 1 to prevent light leakage from the gaps between the key units 20.

[0090] Furthermore, if Fig.15 and Fig.10 As shown, a first boss 13 is provided on the second side of the first shell 1, and the first boss 13 is embedded in the bottom shell 4. The first boss 13 uses the space of the bottom shell 4 to provide space for the second recess 122, thereby ensuring the shading effect while not increasing the thickness of the first shell 1.

[0091] Furthermore, if Figure 3-Figure 7 as well as Fig.10 and Fig.11 As shown, the key 2 includes a key bracket 22 and a key panel 23, the key bracket 22 is rotatably connected to the first shell 1, the key panel 23 is attached to the key bracket 22, the light shielding portion 223 is provided on the key bracket 22, and the projection of the key bracket 22 on the first shell 1 is contained in the first recess 121. When the key 2 is pressed, the key bracket 22 can be embedded in the first recess 121, so that when reserving the pressing gap, the thickness of the key bracket 22 does not need to be calculated, and only the gap between the key panel 23 and the first shell 1 needs to be considered, so that the pressing gap of the key 2 can be reduced and the overall thickness of the panel is thinner.

[0092] Furthermore, if Figure 6 and Fig.21 As shown, Figure 6 This is a schematic diagram of the structure of the button bracket 22 of the three-button smart switch 100. Fig.21It is a structural schematic diagram of a two-button smart switch 100. The shading portion 223 includes a first shading rib 2231, a second shading rib 2232 and a third shading rib 2233. The first shading rib 2231, the second shading rib 2232 and the third shading rib 2233 surround the three sides of the light-transmitting hole 221 to prevent light from leaking out from the side of the button 2 and the tail end of the button 2. Furthermore, the first shading rib 2231 and the second shading rib 2232 are respectively located on both sides of the light-transmitting hole 221, and the third shading rib 2233 is located on the side of the light-transmitting hole 221 away from the rotation connection. Since the closer the shading rib is to the light source, the better the shading effect, in one embodiment, the distance between the third shading rib 2233 and the light-transmitting hole 221 is less than 4 mm, so that the shading effect of the third shading rib 2233 is better. Furthermore, the first light-shielding rib 2231, the second light-shielding rib 2232 and the third light-shielding rib 2233 are connected as a whole to form a tight light-shielding barrier to enhance the light-shielding effect.

[0093] In some embodiments, Figure 7 and Figure 3 As shown, the first housing 1 is provided with a local depression 123 at a position corresponding to the light shielding portion 223, and the local depression 123 is located in the first depression 121. When the button 2 is pressed, the light shielding portion 223 sinks into the local depression 123. The local depression 123 is used to provide a downward pressing space for the light shielding portion 223, thereby reducing the panel thickness of the smart switch 100.

[0094] In some embodiments, the key bracket 22 is made of black plastic so that the key bracket 22 has a light absorbing function and reduces light leakage caused by light reflected by the key bracket 22 .

[0095] In some embodiments, Figure 7 , Fig.10 and Fig.11 As shown, the first side of the first housing 1 is provided with a light shielding enclosure 115 protruding therefrom, and the light shielding enclosure 115 surrounds the light outlet of the light transmission structure 11; the light shielding portion 223 is arranged outside the light shielding enclosure 115. The light outlet of the light transmission structure 11 is the upper end opening of the reflection space 112, the light shielding enclosure 115 protrudes from the upper surface of the first housing 1, and the light shielding portion 223 protrudes from the lower surface of the button bracket 22, and the light shielding enclosure 115 and the light shielding portion 223 form a vertically staggered structure to enhance the light shielding effect.

[0096] Existing smart switches generally include a button, an electronic switch, a reset member, and a middle shell. The button can trigger the corresponding electronic switch when pressed, and reset when pressed down. When the pressing force is removed, the button bounces up under the reset force of the reset member. To ensure that the height of each button is consistent, a limit hook is generally provided at the tail end of the button. The limit hook is connected to the middle shell to limit the limit position of the button's upward bounce. The middle shell is provided with a clamping position adapted to the limit hook. The limit hook and the clamping position will occupy a large space, resulting in a thicker thickness of the button and the middle shell.

[0097] In order to solve the problem that the button and the middle shell are thick, in the embodiment of the present invention, the button 2 has a self-limiting function, and can not be limited by the limit hook to limit the limit position of the upward bounce. Specifically, Figure 3 and Fig. 9 As shown, the intelligent switch 100 further includes a reset member 14, the reset member 14 abuts against the button 2 to provide a reset force; the button 2 is rotatably connected to the first housing 1, the rotation axis of the rotation connection is set as a first rotation axis 151, and the button 2 has a first end close to the first rotation axis 151 and a second end away from the first rotation axis 151; Fig.14 , Fig.13 and Fig. 9 As shown, the direction from the first end to the second end is set as a fourth direction.

[0098] In the fourth direction, the reset member 14 is arranged between the first rotating shaft 151 and the second end, and there is a limit generating distance L1 between the first rotating shaft 151 and the first end, so that when the button 2 is not subjected to pressing force, the first end of the button 2 abuts against the first shell 1, so that the button 2 generates a limit constraint that limits the second end from moving in a direction away from the first shell 1, so that the button 2 can generate an upper limit by its own abutment without the need for a structure similar to a limit hook, so that the structure of the button 2 and the first shell 1 can be simplified and the thickness can be reduced. Among them, when the button 2 is connected to the first shell 1 through an axle hole type connection, the first rotating shaft 151 can be understood as a physical rotating shaft, and when the connection method between the button 2 and the first shell 1 is not an axle hole type connection, the first rotating shaft 151 can also be understood as the axis of the rotational movement of the button 2. The fourth direction is opposite to the first direction described above.

[0099] like Fig.14As shown, the key 2 rotates based on the first rotating shaft 151. When the key 2 is not pressed, the abutting force generated by the first end of the key 2 abutting against the first shell 1 generates an abutting torque relative to the first rotating shaft 151. The abutting torque is balanced with the reset torque generated by the elastic force of the reset member 14, and the force arm of the reset torque is L3. Obviously, the force arm of the abutting torque is the limit generation distance L1. If L1 is too short, the abutting torque will be insufficient, so that the limit constraint is weak and the height of the second end of each key unit 20 is inconsistent; if L1 is too long, the first rotating shaft 151 will be too close to the second end, the area where the key 2 can be pressed will be reduced, and the pressing feel will be poor. In this embodiment, the distance between the first end and the second end is set to L2, and the limit generation distance L1 satisfies the condition: 0.15≤L1 / L2≤0.4, so that the pressing feel of the key 2 is improved while ensuring that the limit constraint is strong.

[0100] Furthermore, if Figure 3 and Fig.10 As shown, the electronic switch 31 is arranged on the side of the first housing 1 away from the button 2; the button 2 is provided with a driving part 224 at the position corresponding to the electronic switch 31, and the driving part 224 directly or indirectly triggers the electronic switch 31; wherein, the direct or indirect triggering of the electronic switch 31 can be understood as that the driving part 224 can directly trigger the electronic switch 31, and can also indirectly trigger the electronic switch 31 through other structures. In one embodiment, a triggering part 142 is arranged between the driving part 224 and the electronic switch 31, and the driving part 224 presses against the triggering part 142 to trigger the electronic switch 31 through the triggering part 142. Fig.14 As shown, in the fourth direction, if the driving part 224 is too close to the first rotating shaft 151, the pressing stroke of the tail end of the key 2 will increase, and the deformation of the key 2 will increase, resulting in the need to design a larger pressing gap of the key 2, which is not conducive to thinning the switch panel; if the driving part 224 is too far away from the first rotating shaft 151, it is more laborious to press the key panel 23, affecting the pressing feel. For this reason, in this embodiment, the distance between the driving part 224 and the first rotating shaft 151 is L3, and L3 satisfies the relationship: 0.25≤L3 / L2≤0.55, so that while controlling the pressing gap of the key 2, the pressing feel of the key 2 is guaranteed.

[0101] Furthermore, if Fig. 9 and Fig.10 As shown, the electronic switch 31 is located between the circuit board 3 and the first housing 1, the first housing 1 is covered on the bottom shell 4, and the circuit board 3 and the electronic switch 31 are both accommodated in the accommodation groove 41. Therefore, the circuit board 3 and the electronic switch 31 do not occupy the thickness of the intelligent switch 100 located outside the wall surface, so that the switch panel can be thinned.

[0102] Furthermore, if Figure 3 , Fig.12 and Fig.14 As shown, the first shell 1 is provided with the first rotating shaft 151, and the first rotating shaft 151 is a physical shaft. The button 2 is provided with a first claw 25 adapted to the first rotating shaft 151, and the first claw 25 is clamped on the first rotating shaft 151 to realize the rotational connection between the button 2 and the first shell 1; the first rotating shaft 151 and the first claw 25 are both arranged in the area where the accommodating groove 41 is projected on the first shell 1, so that when the first claw 25 is clamped on the first rotating shaft 151, the first claw 25 can borrow the space of the accommodating groove 41, so that the structure of the first shell 1 related to the first rotating shaft 151 can sink into the accommodating groove 41, which is conducive to reducing the thickness of the smart switch 100 located outside the wall.

[0103] Furthermore, if Figure 3 , Fig.16 and Fig.14 As shown, the first boss 13 is embedded in the bottom shell 4, and the circuit board 3 is mounted on the first boss 13; the second recess 122 is arranged in the corresponding area of ​​the first boss 13, and the first shaft 151 is arranged in the second recess 122. It can be understood that the shape and size of the first boss 13 correspond to the second recess 122 in the corresponding area of ​​the first boss 13, and the second recess 122 is recessed downward so that the first shell 1 protrudes downward to form the first boss 13. The first shaft 151 is arranged in the second recess 122, so that the structure of the first shell 1 related to the first shaft 151 can sink into the accommodating groove 41.

[0104] In some embodiments, Figure 3 and Fig.13As shown, the button 2 includes a plurality of button units 20, the number and position of the electronic switch 31 correspond to the button units 20, each button unit 20 triggers the corresponding electronic switch 31, and each button unit 20 is connected through a connecting portion 24; wherein, each button unit 20 is connected as a whole through the connecting portion 24, which has the following beneficial effects: the gap width between each button unit 20 can be kept consistent; it is convenient to assemble the button 2 in the first housing 1, and the assembly efficiency is improved; since the circuit board 3 carries a strong electric circuit, when installing the smart switch 100, if the first housing 1 is disassembled, there will be a risk of electric shock, so when installing the smart switch 100, only the button 2 can be disassembled, and the button unit 20 is connected as a whole through the connecting portion 24, which can facilitate the disassembly of the button 2 as a whole, and improve the installation efficiency of the smart switch 100. It is worth mentioning that, thanks to the self-limiting structure of the button 2, the second end of the button 2 does not need to be provided with a structure similar to a limit hook, and it is more convenient for users to disassemble the button 2, further improving the installation efficiency of the smart switch 100.

[0105] However, the key unit 20 being connected as a whole via the connecting portion 24 will bring another problem to the disassembly of the key 2: the key 2 is generally connected to the first shell 1 via a plurality of first claws 25. If the first claws 25 are disassembled one by one, some of the first claws 25 may be in a engaged state while other claws may be in a disengaged state. In this case, the connecting portion 24 may be significantly twisted and deformed, thereby damaging the connecting portion 24.

[0106] To solve this problem, Figure 3 , Fig.12 as well as Fig.13As shown, the number of the first claws 25 is two, which are respectively arranged on both sides of the button 2; the button 2 is provided with at least one first hook 26 between the two first claws 25, the first housing 1 is provided with a second hook 152 adapted to the first hook 26, the first hook 26 is engaged with the second hook 152, and the first hook 26 is located on the connecting line of the two first claws 25; wherein, the clamping force between the first claw 25 and the first rotating shaft 151 is greater than the clamping force between the first hook 26 and the second hook 152, thereby forming a strong and weak matching connection mode, the first claw 25 provides the main limit, and the first hook 26 provides the auxiliary limit. When the button 2 is disassembled, when the first claw 25 is disengaged, the first hook 26 close to the first claw 25 will also automatically disengage, thereby avoiding a large distortion and deformation of the connecting portion 24 and protecting the connecting portion 24 from damage. In addition, when the two first claws 25 are disengaged, the first hook 26 will automatically disengage, thereby facilitating the disassembly of the button 2. It is worth mentioning that since there are only two first claws 25 and they are located on both sides of the button 2, the distance between the two first claws 25 is relatively large. Increasing the deformation distance is equivalent to reducing the deformation per unit length, thereby reducing the twisting deformation of the connecting part 24 and avoiding damage to the connecting part 24.

[0107] It is worth mentioning that the second hook 152 provides a downward constraint on the button 2. When both sides of the button 2 are pressed, the second hook 152 can prevent the middle part of the button 2 from arching upward, thereby improving the constraint on the button unit 20 and preventing the electronic switch 31 from being unable to be triggered. Fig.13 As shown, the second hook 152 protrudes from the first shell 1, so that the second hook 152 can support the button 2. When the middle part of the button 2 is pressed, the second hook 152 can prevent the middle part of the button 2 from being pressed into a depression. In summary, the second hook 152 can constrain the button 2 to arch upward and prevent the button 2 from sinking downward. Its function is similar to that of the first rotating shaft 151, but the clamping force of the first hook 26 is weaker than that of the first claw 25. The second hook 152 cooperates with the first hook 26 to form a constraint similar to a rotation pair, which enhances the stability of the rotational connection between the button 2 and the first shell 1.

[0108] Furthermore, the first hook 26 is located on the connecting line of the two first claws 25 to prevent the first hook 26 from interfering with the rotation of the button 2. A hook protrusion is provided at the end of the first hook 26, and the hook protrusion protrudes laterally from the first hook 26. Fig.14It can be seen from the perspective that when the button 2 is installed on the first shell 1, the end of the hook protrusion is exactly in a straight line with the center position of the first rotating shaft 151, so as to ensure that during the rotation of the button 2, the first hook 26 can always restrain the button 2 from arching upward, and the first hook 26 will not interfere with the rotation of the button 2.

[0109] In some embodiments, Fig.18 As shown, the bottom shell 4 is provided with two first countersunk holes 42, and the first countersunk holes 42 can be inserted with a first screw (not shown in the figure), and the bottom shell 4 is externally mounted by the first screw; the first shell 1 is provided with a first through hole 161 at a position corresponding to the first countersunk hole 42, and the first through hole 161 is used to accommodate the nut of the first screw, so that the nut of the first screw does not increase the thickness of the first shell 1. Further, the four corners of the bottom shell 4 are respectively provided with second countersunk holes 45, and the second countersunk holes 45 can be inserted with a second screw (not shown in the figure), and the bottom shell 4 is externally mounted by the second screw, and the first shell 1 is provided with a second through hole 162 at a position corresponding to the second countersunk hole 45, and the second through hole 162 is used to accommodate the nut of the second screw. Among them, the first screw is suitable for connecting a dark box, and the second screw is suitable for connecting a wood veneer, a cabinet, a desktop, etc.

[0110] like Fig. 20 As shown, a protrusion 43 is provided at a position corresponding to the first countersunk hole 42 on the side of the bottom shell 4 facing away from the button 2, and the protrusion 43 makes the side wall of the first countersunk hole 42 not protrude from the side of the bottom shell 4 facing the button 2, that is, the protrusion 43 provides a sinking space for the first countersunk hole 42, so that the nut of the first screw can be partially sunk to the upper surface of the bottom shell 4, thereby reducing the volume of the nut located in the first shell 1 and avoiding interference between the first shell 1 and the nut of the first screw.

[0111] In some embodiments, Figure 3 and Fig.10 As shown, the reset member 14 includes an elastic arm 141 extending from the first housing 1 and a trigger portion 142 disposed at the free end of the elastic arm 141, the trigger portion 142 is located between the driving portion 224 and the electronic switch 31, and the driving portion 224 indirectly triggers the electronic switch 31 by driving the trigger portion 142; the elastic force of the elastic arm 141 is transmitted to the driving portion 224 through the trigger portion 142 to provide a reset force. The trigger portion 142 and the elastic arm 141 are integrally formed in the first housing 1.

[0112] In some embodiments, Figure 3 and Fig.13As shown, the key 2 includes a key bracket 22 and a key panel 23 fixedly connected to the key bracket 22, the key bracket 22 is rotatably connected to the first shell 1, and the key bracket 22 is provided with an abutting protrusion 222 at a position close to the first end toward the first shell 1, and the abutting protrusion 222 abuts against the first shell 1 to limit the second end of the key 2 from moving in a direction away from the first shell 1. Among them, the key 2 of this embodiment abuts against the first shell 1 through the abutting protrusion 222 to achieve the second end limit. Compared with the key 2 abutting against the first shell 1 through a plane or an edge, the height of the abutting protrusion 222 is easier to adjust and the dimensional accuracy is easier to control. The R&D personnel can adjust the limit position of the second end of the key 2 by adjusting the height of the abutting protrusion 222, so as to obtain the optimal height of the abutting protrusion 222 through multiple tests, and realize the precise control of the limit position of the second end. Further, the abutting protrusion 222 is located at the end position of the first end of the key bracket 2.

[0113] When the number of buttons of an existing smart switch is greater than two, the gap width between the buttons will be uneven. For this reason, the researchers have designed a one-piece button, that is, the buttons are connected together during manufacturing, so that the gap width between the buttons is consistent. However, one-piece buttons are generally made of plastic material and are injection molded in one piece, which has poor rigidity. When the buttons are thin, the deformation of the buttons is large, and it is easy to fail to trigger the electronic switch. To solve this problem, in the prior art, the only way to improve the anti-deformation ability of the buttons is to increase the thickness of the buttons. However, increasing the thickness of the buttons is not only not conducive to thinning the switch panel, but also causes a linkage effect between the buttons, causing the electronic switch to be triggered by the linkage of the buttons.

[0114] To solve the above problems, in an embodiment of the present invention, Figure 3-Figure 6 As shown, the button 2 includes a button bracket 22 and a button panel 23; the button bracket 22 is rotatably connected to the first shell 1, and the button bracket 22 includes a plurality of bracket units 225, and each of the bracket units 225 is connected as a whole through a connecting portion 24; the number and position of the electronic switches 31 correspond to the bracket units 225, and each of the bracket units 225 triggers the corresponding electronic switch 31 respectively; wherein, the button panel 23 includes a plurality of panel units 231, and the panel units 231 are fixedly connected to the bracket units 225 one by one, and the rigidity of the panel units 231 is greater than the rigidity of the bracket units 225.

[0115] In this embodiment, the panel unit 231 and the bracket unit 225 are fixedly connected as a whole, which improves the deformation resistance of the bracket unit 225 and avoids the situation where the electronic switch 31 cannot be triggered due to excessive deformation. At the same time, since the panel unit 231 has a large rigidity, the thickness can be reduced while ensuring a small deformation, thereby reducing the overall thickness of the button 2. Moreover, since the connecting part 24 and the bracket unit 225 are connected as one body, the rigidity of the connecting part 24 and the bracket unit 225 are relatively low, so that the flexibility of the connecting part 24 is retained, thereby reducing the linkage between the bracket units 225 and avoiding the electronic switch 31 being triggered by the linkage of the button bracket 22.

[0116] The linkage triggering can be understood as when a bracket unit 225 is pressed to trigger the corresponding electronic switch 31, another bracket unit 225 adjacent to the bracket unit 225 generates linkage, causing the adjacent electronic switch 31 to be triggered by mistake. The bracket unit 225 triggers the electronic switch 31 by direct contact or by driving other parts. In one embodiment, a triggering part 142 is provided between the bracket unit 225 and the electronic switch 31, and the bracket unit 225 indirectly triggers the electronic switch 31 by contacting and driving the triggering part 142. The panel unit 231 is made of a material with higher rigidity, and the bracket unit 225 is made of a material with lower rigidity. In one embodiment, the bracket unit 225 and the connecting part 24 are integrally injection molded with a plastic material, and the panel unit 231 is constructed as an AG frosted glass sheet. The panel unit 231 is fixedly connected to the bracket unit 225 by bonding, clamping, riveting or other connection methods. In one embodiment, the panel unit 231 is bonded to the bracket unit 225.

[0117] Furthermore, if Figure 6 As shown, the key bracket 22 has a third end close to the first rotating shaft 151 and a fourth end away from the first rotating shaft 151, and the direction from the third end to the fourth end is set as the fifth direction. In the fifth direction, the first rotating shaft 151 is located within the length range of the connecting portion 24. According to the lever principle, in the fifth direction, the closer the key 2 is to the first rotating shaft 151, the smaller the rotation amplitude. In this embodiment, the first rotating shaft 151 is set at the corresponding position of the connecting portion 24, so that when the bracket unit 225 rotates based on the first rotating shaft 151, the rotation amplitude of the bracket unit 225 at the corresponding position of the connecting portion 24 is the smallest, and accordingly, the deformation of the connecting portion 24 is the smallest, thereby weakening the linkage effect between adjacent bracket units 225, and preventing the electronic switch 31 from being triggered by the key bracket 22. Among them, the third end of the key bracket 22 corresponds to the first end of the key 2, and the fourth end of the key bracket 22 corresponds to the second end of the key 2.

[0118] It is worth noting that if the deformation of the connecting portion 24 is too large, the portion where the bracket unit 225 is connected to the connecting portion 24 will also deform along with the connecting portion 24. Since the key panel 23 is relatively rigid and not easily deformed, it will inevitably cause a force to separate the key bracket 22 and the key panel 23, causing the key panel 23 to become debonded or damaged. In this embodiment, the first rotating shaft 151 is set at a position corresponding to the connecting portion 24 to minimize the deformation of the connecting portion 24, thereby avoiding debonding or damage to the key panel 23. Among them, the fifth direction is the same as the fourth direction described above.

[0119] In the existing one-piece buttons, the connection part is generally arranged at the end of the button. According to the lever principle, the farther the button 2 is from the first rotating shaft 151, the greater the rotation amplitude is. Correspondingly, the deformation of the connection part 24 is also greater. According to the above records, if the connection part 24 is deformed too much, the linkage effect between adjacent bracket units 225 will be obvious, and it is easy to cause the button panel 23 to be debonded or damaged. In order to avoid the deformation of the connection part 24 being too large, in this embodiment, if the deformation of the connection part 24 is too large, Figure 4 As shown, two adjacent bracket units 225 are divided by a first splitting seam 271 and a second splitting seam 272, wherein the first splitting seam 271 extends from the connecting portion 24 to the third end, and the second splitting seam 272 extends from the connecting portion 24 to the fourth end. That is, in the one-piece key 2 provided in this embodiment, the connecting portion 24 is not located at the end of the key 2, thereby avoiding excessive deformation of the connecting portion 24 caused by excessive rotation of the end of the key 2, thereby weakening the linkage effect between the bracket units 225 and avoiding debonding or damage to the key panel 23.

[0120] If the tail end of the button 2 is pressed, the tail end of the button 2 is subjected to downward pressing force, the button 2 is subjected to downward restraining force at the position corresponding to the first rotating shaft 151, and the button 2 is subjected to upward elastic force at the position corresponding to the reset member 14; if the distance between the position of the first rotating shaft 151 and the tail end of the button 2 is too large, the deformation of the button 2 will be too large, and the electronic switch 31 may fail to be triggered. Figure 4 As shown, in the fifth direction, the length of the first dividing seam 271 is L4, the length of the button bracket 22 is L5, and L4 and L5 satisfy the relationship: L4 / L5≥0.1, so that the positions of the connecting portion 24 and the first rotating shaft 151 are closer to the tail end of the button 2, shortening the distance between the tail end of the button 2 and the first rotating shaft 151, reducing the deformation amount caused by pressing the button 2, and avoiding the situation where the electronic switch 31 cannot be triggered.

[0121] Furthermore, if Figure 4As shown, in the fifth direction, the length of the connection portion 24 is L6. If L6 is too short, the connection strength of the connection portion 24 will be low, which will lead to a loose connection between the key units 20. If L6 is too long, the deformation of the connection portion 24 will be large, and the key panel 23 will be at risk of debonding or damage, and the linkage effect between the bracket units 225 will be strong. For this reason, in this embodiment, L6 satisfies the relationship: 0.1≤L6 / L5≤0.3, so that the connection portion 24 has a small deformation while ensuring the connection strength.

[0122] Furthermore, if Fig.12 As shown, the direction of the button bracket 22 toward the first housing 1 is the sixth direction (not shown in the figure). In the sixth direction, the thickness of the connecting portion 24 is d1, and the d1 satisfies the condition: 1.2mm≤d1≤2mm, so that the connecting portion 24 has a certain flexibility while ensuring the connection strength to weaken the linkage effect between the bracket units 225. Fig.12 The vertical downward direction.

[0123] In some embodiments, Fig.12 As shown, the connecting portion 24 protrudes from the side of the button bracket 22 facing the first shell 1, and the connecting portion 24 is recessed in the side of the button bracket 22 facing away from the first shell 1, so that the cross-section of the connecting portion 24 presents a downwardly recessed U-shape. Compared with the direct-connection type connecting portion 24, the present embodiment adopts a U-shaped connecting portion 24, which increases the width of the connecting portion 24 in disguise, thereby increasing the flexibility of the connecting portion 24 and preventing the connecting portion 24 from causing the bracket unit 225 to deform and cause the button panel 23 to become debonded or damaged.

[0124] In some embodiments, Figure 5 , Figure 3 as well as Fig.10 As shown, in the fifth direction, the length of the key panel 23 is greater than the length of the key bracket 22; the first housing 1 is provided with the first recess 121, and when the panel unit 231 is pressed, the fourth end of the corresponding bracket unit 225 is embedded in the first recess 121, which is equivalent to only the key panel 23 of the key 2 being located above the first housing 1, and the key bracket 22 sinking into the first housing 1, and the entire key 2 does not need to be located above the first housing 1, thereby reducing the overall thickness of the switch panel. Thanks to the greater rigidity of the key panel 23, the key panel 23 can be made very thin, and finally presents the visual effect of an extremely ultra-thin key 2.

[0125] Furthermore, since the bracket unit 225 will sink into the first recess 121 when pressed, the thickness of the bracket unit 225 does not need to be taken into account when reserving a pressing gap. Only the gap between the button panel 23 and the first shell 1 needs to be considered, so that the pressing gap of the button 2 is reduced and the overall thickness of the panel is thinner.

[0126] In some embodiments, Fig. 9 , Fig.14 and Fig.13 As shown, the reset member 14 abuts against the key bracket 22 to provide a reset force. When the key bracket 22 is not pressed, the third end of the key bracket 22 abuts against the first shell 1 to limit the fourth end of the key bracket 22 from moving in a direction away from the first shell 1, so that the key 2 can generate an upper limit position through its own abutment without a structure similar to a limit hook, which is conducive to reducing the thickness of the key 2 and the first shell 1. Among them, the principle and technical details of the self-limiting of the key 2 are described in detail above and will not be repeated here.

[0127] In some embodiments, Figure 3 and Fig. 9 As shown, the first shell 1 is covered on the bottom shell 4, the circuit board 3 is accommodated in the accommodating groove 41 of the bottom shell 4, the circuit board 3 carries a weak current circuit and a strong current circuit, and the button 2 covers the first through hole 161 of the first shell 1. Among them, the circuit board 3 is accommodated in the accommodating recess, which can prevent the circuit board 3 from occupying the space of the first shell 1 and make the first shell 1 thinner. Since the circuit board 3 carries a strong current circuit, there is a risk of electric shock if the first shell 1 is disassembled when installing the smart switch 100. Therefore, when installing the smart switch 100, only the button 2 can be disassembled to operate the mounting screws, and the bracket unit 225 is connected as a whole through the connecting portion 24 to facilitate the disassembly of the button 2 as a whole, thereby improving the installation efficiency of the smart switch 100.

[0128] The electronic switches of the smart switches on the market generally use touch switches or micro switches 311. The internal structure of the micro switch 311 is relatively complex, such as Fig.25 As shown, it is a schematic diagram of the structure of the micro switch 311. The micro switch 311 includes a protective shell 3111, a driving rod 3112, a contact system and a spring system 3113. When the driving rod 3112 is pressed down beyond the limit stroke, it is easy to damage the spring system 3113. The smart switch on the market is generally triggered directly by a button. The button extends a trigger rod downward, and the trigger rod is used to abut the micro switch 311. Since the trigger rod is thin, the contact surface with the micro switch 311 is very small. When the button is pressed, the pressure generated by the trigger rod is large, which is easy to press the driving rod 3112 beyond the stroke and cause damage to the micro switch 311.

[0129] In order to solve the problem that the micro switch 311 is easily damaged, in an embodiment of the present invention, Fig.10 and Fig.25 As shown, the electronic switch 31 is a micro switch 311, which includes a protective shell 3111 and a driving rod 3112 capable of telescopic movement relative to the protective shell 3111; the button 2 presses the driving rod 3112 of the micro switch 311 through the trigger part 142, and the driving rod 3112 is pressed to produce a retraction movement to trigger the micro switch 311.

[0130] Among them, Fig.10 , Figure 7 and Figure 8 As shown, Figure 8 The figure is a schematic diagram of the position and area relationship between the trigger part 142 and the micro switch 311. The trigger part 142 has a first surface. The trigger part 142 drives the driving rod 3112 through the first surface. The first surface at least covers a specified area of ​​the upper surface of the protective shell 3111. The specified area is set as follows: when the first surface drives the driving rod 3112 to retract the protective shell 3111, the first surface abuts against the upper surface of the protective shell 3111, and the protective shell 3111 supports the trigger part 142, thereby limiting the trigger part 142 and the button 2 from continuing to press.

[0131] In this embodiment, the button 2 presses the driving rod 3112 through the trigger part 142. Since the first surface covers at least a specified area of ​​the upper surface of the protective shell 3111, when the first surface abuts against the protective shell 3111, the contact area between the first surface and the protective shell 3111 is larger and the abutting pressure is smaller, thereby preventing the protective shell 3111 from being crushed by the trigger part 142; and the trigger part 142 is supported by the protective shell 3111, thereby preventing the driving rod 3112 from being pressed beyond the limit stroke, thereby protecting the internal structure of the micro switch 3111 from damage.

[0132] The first surface may be a plane or a curved surface. In this embodiment, the first surface is Fig.10 The lower surface of the trigger portion 142. The retraction of the driving rod 3112 into the protective shell 3111 can be understood as the driving rod 3112 moving to not protrude from the upper surface of the protective shell 3111.

[0133] In addition, it is worth noting that the pressing movement of the button of the existing intelligent switch needs to have a lower limit, and the lower limit of the button is generally provided by the first shell, and the electronic switch is generally set on the circuit board, and the circuit board is set on the first shell or the bottom shell, which leads to a long dimension chain between the button and the electronic switch, which is easy to form error accumulation, and finally the electronic switch may not be triggered when the button moves to the lower limit position. In this embodiment, the protective shell 3111 of the micro switch 311 supports the button 2 through the trigger part 142, and the lower limit of the button 2 is provided by the protective shell 3111 of the micro switch 311. The dimension chain between the micro switch 311 and the button 2 is extremely short, making the lower limit of the button 2 more accurate; and when the trigger part 142 abuts against the protective shell 3111, the micro switch 311 has been triggered, that is, when the button 2 moves to the lower limit, the micro switch 311 will inevitably be triggered, and the situation that the micro switch 311 is not triggered when the button 2 moves to the lower limit position will not occur.

[0134] Furthermore, the designated area is 20% of the upper surface area of ​​the protective shell 3111 to ensure that the contact area between the first surface and the protective shell 3111 is large enough, so that the abutting pressure is small enough to ensure that the protective shell 3111 will not be deformed under the pressure of the first surface, and can stably support the trigger part 142 to avoid damage to the micro switch 311.

[0135] Furthermore, if Fig.10 and Figure 8 As shown, the trigger portion 142 is constructed as a plate-like structure, and the first surface is the entire surface of the trigger portion 142 facing the micro switch 311; thereby, the first surface is increased as much as possible, and there is no protruding structure on the first surface to ensure that the first surface can cover at least 20% of the upper surface area of ​​the protective shell 3111 to avoid damage to the micro switch 311.

[0136] Furthermore, if Figure 7-Figure 10 As shown, the first shell 1 is extended with the elastic arm 141 , and the trigger portion 142 is integrally formed at the free end of the elastic arm 141 .

[0137] Furthermore, if Figure 8 As shown, the end of the trigger portion 142 away from the elastic arm 141 is semicircular, and the driving rod 3112 of the micro switch 311 is arranged at a position close to the center of the semicircle to reduce the pressing stress generated by the trigger portion 142.

[0138] In some embodiments, Figure 7 and Fig.10As shown, the elastic arm 141 is combined with the trigger part 142 to form a reset member 14, and the reset member 14 provides a reset force for the button 2; wherein the trigger part 142 can not only protect the micro switch 311 from damage, but also cooperate with the protective shell 3111 to provide a lower limit for the button 2, and can also provide a reset force, and has a simple structure, does not occupy the thickness of the first shell 1, and provides structural support for thinning the first shell 1.

[0139] Furthermore, the trigger part 142 is provided with a support protrusion 143 toward the button 2, and the support protrusion 143 is in contact with the button 2, so that when the button 2 is not pressed, the elastic arm 141 is in a pre-compressed state, and the trigger part 142 provides a pre-tightening force, so that the button 2 will not be loose. In addition, by adjusting the height of the support protrusion 143, the size of the pre-tightening force and the reset force provided by the trigger part 142 can be adjusted, so that the pressing feel of the button 2 is improved.

[0140] When the button 2 is pressed, the button 2 and the support protrusion 143 will have a horizontal relative movement, which will cause friction and make the pressing feel sticky. Figure 3 and Fig.10 As shown, the button 2 is provided with a driving portion 224 at a position corresponding to the supporting protrusion 143, and the button 2 is abutted against the supporting protrusion 143 through the driving portion 224; the driving portion 224 and the supporting protrusion 143 are both constructed as strip-shaped protrusions, and the two are arranged criss-cross so that the relative movement between the driving portion 224 and the supporting protrusion 143 will not cause interference, thereby avoiding a sticky feeling when pressing.

[0141] In some embodiments, Fig.10 and Fig.15 As shown, Fig.15 This is a perspective after the first housing 1 is turned upside down. A third recess 17 is provided on one side of the first housing 1 facing the micro switch 311 at a position corresponding to the micro switch 311, and the micro switch 311 is embedded in the third recess 17, so that the micro switch 311 is closer to the trigger portion 142, so that the micro switch 311 can be successfully triggered without providing a protruding structure on the lower surface of the trigger portion 142.

[0142] In some embodiments, Fig. 9 and Fig.10As shown, the first housing 1 is covered on the bottom housing 4, the circuit board 3 is installed on the side of the first housing 1 facing the bottom housing 4, and the micro switch 311 is arranged on the circuit board 3. The circuit board 3 is installed on the first housing 1, so that the distance between the micro switch 311 and the first housing 1 is closer, thereby shortening the distance between the micro switch 311 and the trigger part 142, so as to ensure that the micro switch 311 can be successfully triggered even if the lower surface of the trigger part 142 is not provided with a protruding structure, thereby protecting the micro switch 311 from damage.

[0143] Furthermore, if Figure 8 and Figure 7 As shown, there are three trigger parts 142, and the elastic arms 141 and the trigger parts 142 are arranged one by one. The trigger parts 142 on both sides are bent toward the outside respectively. The three elastic arms 141 and the three trigger parts 142 are all located in the area where the accommodating groove 41 is projected on the first shell 1 to avoid interference between the elastic arms 141 and the first through hole 161. Among them, the elastic arms 141 are all straight arms extending toward the fourth direction. Since the first shell 1 is provided with the first through hole 161, the positions of the left and right elastic arms 141 are offset toward the middle respectively. In order to make the positions of the left and right trigger parts 142 correspond to the micro switch 311, the trigger part 142 on the left is bent to the left, and the trigger part 142 on the right is bent to the right. The trigger part 142 in the middle extends in the same direction as the elastic arm 141, and the ends of the trigger parts 142 are all semicircular. The triggering parts 142 on the left and right sides respectively cover 39% of the area of ​​the upper surface of the corresponding protective shell 3111 , and the triggering part 142 in the middle covers 40% of the area of ​​the upper surface of the corresponding protective shell 3111 .

[0144] Existing smart switches are usually installed by screw fixing. However, the screw tightening process will cause the bottom shell to deform, and the deformation of the bottom shell may be transmitted to the circuit board and the electronic switch, causing them to be displaced, thereby affecting the normal triggering of the electronic switch. To avoid this problem, in the prior art, the circuit board carrying weak current is usually fixed on the middle shell. Since the middle shell will not be affected by the deformation of the bottom shell, the deformation of the bottom shell will not affect the circuit board. This solution generally uses two methods to fix the circuit board: the first is to fix the circuit board directly to the middle shell with screws; the second is to fix a guard plate on the lower side of the middle shell, and the circuit board is clamped and fixed between the guard plate and the middle shell. Although these two methods can isolate the impact of the deformation of the bottom shell to a certain extent, their installation and disassembly process is relatively cumbersome and it is difficult to improve assembly efficiency.

[0145] To solve the above problems, in an embodiment of the present invention, a new intelligent switch 100 is proposed, which adopts a new fixing structure. The structure adopts a first housing 1 provided with a positioning portion 18 for positioning the circuit board 3, which can ensure stability while improving the convenience of disassembly and assembly.

[0146] Specific as Fig. 9 and Fig.10 As shown, the circuit board 3 has a first circuit surface facing the button 2 and a second circuit surface facing away from the button 2. The first circuit surface is provided with an electronic switch 31. The button 2 can directly or indirectly trigger the electronic switch 31 under the action of pressing force.

[0147] According to an embodiment of the present disclosure, the button 2 can directly trigger the electronic switch 31, for example, directly through the hole provided on the first housing 1 to trigger the electronic switch 31 on the circuit board 3. The button 2 can also indirectly trigger the electronic switch 31, for example, by assisting in triggering the electronic switch 31 through some other structures. With respect to indirect triggering, a possible implementation method is provided in an embodiment of the disclosure, specifically: a triggering portion 142 is provided between the button 2 and the electronic switch 31, and the button 2 presses against the triggering portion 142 to trigger the electronic switch 31 through the triggering portion 142.

[0148] In addition, in a possible implementation, the first circuit surface of the circuit board 3 can be understood as Fig.19 The upper surface of the circuit board 3, the second circuit surface can be understood as Fig.19 On this basis, the thickness direction of the circuit board 3 can be understood as Fig.19 In the vertical downward direction.

[0149] The first housing 1 is in contact with the first circuit surface. Figure 15-19 As shown, Fig.15 and Fig.16 For the perspective after flipping upside down, the first shell 1 is provided with a plurality of positioning portions 18 toward the circuit board 3, and the positioning portions 18 include a positioning unit, which protrudes out of the second circuit surface and abuts against the circuit board 3, so that when the pressing force applied to the button 2 is transmitted to the circuit board 3 through the electronic switch 31, the positioning unit locks the displacement of the circuit board 3 in the thickness direction, so that the electronic switch 31 is triggered.

[0150] Furthermore, during the installation of the circuit board 3, the first circuit surface abuts against the first housing 1, and the second circuit surface is abutted and supported by the positioning unit, thereby achieving stable positioning of the circuit board 3 between the first housing 1 and the positioning unit. During operation, when the button 2 is pressed, the pressing force is transmitted to the circuit board 3 through the electronic switch 31, and the displacement of the circuit board 3 in the thickness direction is locked by the upward positioning force provided by the positioning unit, ensuring reliable triggering of the electronic switch 31.

[0151] Through this structural design, the displacement of the circuit board 3 is firmly locked by the positioning portion 18, and reliable support and positioning of the circuit board 3 can be achieved without the need for screws, which greatly improves the convenience of disassembly and assembly of the circuit board 3.

[0152] It is worth mentioning that in the embodiment of the present disclosure, the design of the positioning unit protruding from the circuit board 3 ensures the stability of the positioning of the circuit board 3 and sufficient supporting effect, thereby avoiding unnecessary displacement of the circuit board 3 under the action of pressing force and ensuring that the switch can be successfully triggered.

[0153] In some embodiments, Fig.18 and Fig.19 As shown, the circuit board 3 carries a strong current circuit and a weak current circuit, and the bottom shell 4 is provided with a receiving groove 41, and the circuit board 3 and the positioning portion 18 are both accommodated in the receiving groove 41. Furthermore, the circuit board 3 of this embodiment carries both the strong current circuit and the weak current circuit, and there is no need to separately set up a strong current circuit board 3, nor is there a need to set up a partition, thereby avoiding interference between the positioning unit and the partition. In addition, the circuit board 3 and the positioning portion 18 are both arranged in the receiving groove 41, which avoids interference between the positioning unit and the bottom shell 4, and also avoids the circuit board 3 and the positioning portion 18 occupying the thickness of the first shell 1, so that the panel thickness of the intelligent switch 100 can be reduced.

[0154] Furthermore, if Fig.15 and Fig.16As shown, the circuit board 3 has a first connection end and a second connection end away from the first connection end, and the plurality of positioning portions 18 include at least one first positioning portion 182 and at least two second positioning portions 183; the first positioning portion 182 is arranged at a position corresponding to the first connection end, and the second positioning portion 183 is arranged at a position close to the second connection end; the first positioning portion 182 includes a first connecting arm 1821 extending from the first shell 1 and a first positioning unit 1822 arranged at the end of the first connecting arm 1821, and the second positioning portion 183 includes a second connecting arm 1831 extending from the first shell 1 and a second positioning unit 1832 arranged at the end of the second connecting arm 1831, and the first positioning unit 1822 and the second positioning unit 1832 are respectively in contact with the second circuit surface of the circuit board 3 to lock the displacement of the circuit board 3 in the thickness direction. Wherein, as Fig.16 As shown, the rigidity of the first connecting arm 1821 is greater than that of the second connecting arm 1831. Since the first connecting arm 1821 has a higher rigidity and is not easily deformed, while the second connecting arm 1831 has a lower rigidity and is easily deformed, when installing the circuit board 3, the first connecting end is first inserted between the first positioning unit 1822 and the first shell 1, and then the second connecting end is pressed toward the first shell 1. The second positioning unit 1832 is squeezed by the circuit board 3 and drives the second connecting arm 1831 to undergo elastic deformation, and then the circuit board 3 is inserted between the second positioning unit 1832 and the first shell 1 to complete the installation of the circuit board 3. The entire installation process is simple and quick, which is conducive to improving assembly efficiency.

[0155] Among them, the first positioning unit 1822 and the second positioning unit 1832 are both the positioning units. The second positioning portion 183 is arranged at a position close to the second connection end, which can be understood as the second positioning portion 183 can be arranged at the end position corresponding to the second connection end, or can be arranged at a position close to the second connection end on both sides of the circuit board 3. In one embodiment, the second positioning portion 183 is arranged on both sides of the circuit board 3. This embodiment adopts at least one first positioning portion 182 with higher rigidity to cooperate with at least two second positioning portions 183 with lower rigidity, which can not only improve the assembly efficiency of the circuit board 3, but also provide a stable positioning force, and when disassembling the circuit board 3, the second positioning portion 183 with lower rigidity is conducive to prying, and the circuit board 3 can be disassembled by prying open the two second positioning portions 183 one by one. The disassembly process is relatively simple and quick, which is convenient for the repair and replacement of the circuit board 3.

[0156] Since the rigidity of the second connecting arm 1831 is relatively low, there is a risk that the circuit board 3 will be detached when the button 2 is pressed. Fig. 9As shown, the bottom shell 4 is provided with a receiving groove 41, the circuit board 3 is received in the receiving groove 41, and the second connecting arm 1831 is abutted by the side wall of the receiving groove 41 to enhance the anti-deformation capability of the second connecting arm 1831, so as to prevent the circuit board 3 from being separated from the second positioning portion 183 when the button 2 is pressed. When the first housing 1 is detached from the bottom shell 4, the second connecting arm 1831 is no longer abutted by the bottom shell 4, and the low rigidity characteristic is restored, which facilitates the installation and removal of the circuit board 3. In this embodiment, the anti-deformation capability of the second connecting arm 1831 is enhanced by the bottom shell 4, which not only prevents the circuit board 3 from being separated during use, but also retains the advantage of easy assembly and disassembly of the circuit board 3.

[0157] Furthermore, if Fig.19 and Fig.18 As shown, the upper edge of the receiving groove 41 is provided with a first guiding slope 44, and the bottom of the second connecting arm 1831 is provided with a second guiding slope 1833, and the second guiding slope 1833 is provided on the side of the second connecting arm 1831 away from the circuit board 3. The first guiding slope 44 cooperates with the second guiding slope 1833 to facilitate the second positioning portion 183 to be installed in the receiving groove 41. In an exemplary embodiment, Fig.18 As shown in FIG. 4 , the first guiding slope 44 surrounds the upper edge of the accommodating groove 41. Fig.19 As shown, when the first shell 1 is installed on the bottom shell 4 , the first boss 13 of the first shell 1 is embedded in the first guiding inclined surface 44 .

[0158] In one embodiment, if Fig.16 and Fig.15 As shown, the circuit board 3 includes a first side edge and a second side edge arranged between the first connection end and the second connection end, and the first side edge and the second side edge are respectively located on both sides of the circuit board 3; the number of the second positioning parts 183 is two, and the second positioning units 1832 of the two second positioning parts 183 are respectively abutted against the first side edge and the second side edge. Among them, the two second positioning parts 183 are located on both sides of the circuit board 3 and are arranged oppositely, so that the two second positioning parts 183 with lower rigidity are subjected to a balanced force, thereby accurately locking the circuit board 3 in the position between the two second positioning parts 183. It is avoided that the second positioning part 183 with lower rigidity is arranged oppositely to the first positioning part 182 with higher rigidity, causing the second positioning part 183 to be squeezed.

[0159] Furthermore, if Fig.16 and Fig.15As shown, the number of the first positioning parts 182 is two, and the first positioning units 1822 of the two first positioning parts 182 are respectively abutted against the first connection end of the circuit board 3, wherein the two first positioning parts 182 and the two second positioning parts 183 are respectively abutted against the circuit board 3, which can improve the positioning force and make the connection of the circuit board 3 more stable. Moreover, when installing the circuit board 3, the first connection end of the circuit board 3 is abutted by the two first positioning parts 182, which can constrain the direction of the circuit board 3 in the horizontal plane, making it easier for the circuit board 3 to be accurately inserted into the first positioning parts 182, thereby improving the installation efficiency of the circuit board 3.

[0160] In one implementation, the width of the first connecting arm 1821 is greater than the width of the second connecting arm 1831, so that the rigidity of the first connecting arm 1821 is greater than the rigidity of the second connecting arm 1831. In some embodiments, the thickness of the first connecting arm 1821 is greater than the thickness of the second connecting arm 1831, so that the rigidity of the first connecting arm 1821 is greater than the rigidity of the second connecting arm 1831. In some embodiments, a first reinforcing rib is disposed on a side of the first connecting arm 1821 facing away from the circuit board 3, and a second reinforcing rib is disposed on a side of the second connecting arm 1831 facing away from the circuit board 3, and the width of the first reinforcing rib is greater than the second reinforcing rib, so that the rigidity of the first connecting arm 1821 is greater than the rigidity of the second connecting arm 1831.

[0161] In some embodiments, Fig.10 As shown, the electronic switch 31 is located on the connecting line of the two second positioning portions 183, so that the positioning force provided by the second positioning portions 183 acts more directly on the electronic switch 31, making the positioning of the electronic switch 31 more stable and preventing the electronic switch 31 from being pressed and displaced.

[0162] In some embodiments, Figure 15-17 As shown, the circuit board 3 is provided with a first positioning hole 38, and the first housing 1 is provided with a first positioning column 19, and the first positioning column 19 is inserted into the first positioning hole 38 to lock the displacement of the circuit board 3 in parallel with the first circuit surface. The direction parallel to the surface of the first circuit board 3 can be understood as the horizontal direction, and the first positioning column 19 can improve the positioning accuracy of the circuit board 3 in the horizontal direction, and cooperate with the first positioning portion 182 and the second positioning portion 183 to achieve accurate positioning of the circuit board 3 in the horizontal and vertical directions, thereby ensuring that the electronic switch 31 is accurately triggered.

[0163] Furthermore, the first positioning hole 38 is arranged at a position of the circuit board 3 close to the second connection end to improve the positioning accuracy of the circuit board 3 near the electronic switch 31 and ensure the positioning accuracy of the electronic switch 31. Fig.16As shown, due to the high rigidity of the first positioning portion 182, the position of the circuit board 3 in the horizontal direction is mainly positioned by the positioning column and the two first positioning portions 182. Arranging the positioning column on the opposite side of the first positioning portion 182 can increase the distance between the positioning column and the first positioning portion 182, thereby improving the positioning accuracy of the circuit board 3.

[0164] like Figure 1-Figure 20 It is a three-button smart switch 100. Fig.21 and Fig. 22 It is a two-button smart switch 100. Fig.23 and Fig.24 It is a single-button smart switch 100, wherein the difference between the double-button smart switch 100, the single-button smart switch 100 and the three-button smart switch 100 is that the number of the key units 20 of the three-button smart switch 100 is three, and accordingly, the number of the micro switch 311, the panel unit 231, the driving unit 224, the triggering unit 142, the elastic arm 141, the light-emitting member 35, the light-transmitting structure 11, the light-transmitting hole 221, the light-transmitting area 21 and the relay 32 are all three, and the number of the wiring terminals 36 is five; the number of the key units 20 of the double-button smart switch 100 is There are two of them, and accordingly, the number of the micro switch 311, the panel unit 231, the driving part 224, the trigger part 142, the elastic arm 141, the light-emitting part 35, the light-transmitting structure 11, the light-transmitting hole 221, the light-transmitting area 21 and the relay 32 are all two, and the number of the wiring terminals 36 is four; the number of the button unit 20 of the single-button smart switch 100 is one, and accordingly, the number of the micro switch 311, the panel unit 231, the light-transmitting area 21 and the relay 32 are all one, the button panel 23 is a complete panel, and the number of the wiring terminals 36 is three.

[0165] It is worth noting that the key bracket 22 and the first housing 1 of the single-button smart switch 100 are identical in structure to the three-button smart switch 100, which can save mold costs. Therefore, the number of the driving part 224, the trigger part 142, the elastic arm 141, the light-emitting member 35, the light-transmitting structure 11 and the light-transmitting hole 221 of the single-button smart switch 100 is three.

[0166] In addition, compared with the three-button smart switch 100, the position layout of the micro switch 311, the light-emitting component 35, the light-transmitting structure 11, the light-transmitting hole 221, and the light-transmitting area 21 of the two-button smart switch 100 will be adaptively adjusted as the number of key units 20 changes, and the position of the shading portion 223 and the local recess 123 will also be slightly adjusted as the number of keys 2 changes, and the positions of the relay 32 and the wireless communication module 33 will also be slightly different. The circuits of the two-button smart switch 100, the single-button smart switch 100 and the three-button smart switch 100 will be slightly different. In addition to the above differences, the other structures of the two-button smart switch 100, the single-button smart switch 100 and the three-button smart switch 100 are the same.

[0167] It is worth noting that the structures of the elastic arms 141 and the trigger parts 142 of the double-button smart switch 100, the single-button smart switch 100 and the three-button smart switch 100 are exactly the same, and the number of the elastic arms 141 and the trigger parts 142 will not change with the number of the button units 20.

[0168] In another embodiment of the present invention, Fig.26 As shown, an integrated button 2 is provided. Figure 1-Figure 20 The difference between the illustrated embodiments is that the button bracket 22 and the button panel 23 are integrated into one, and the button 2 is integrally injection molded using a plastic material; since the rigidity of plastic is relatively low, reinforcing ribs are provided on the back of the button 2 to enhance the deformation resistance of the button 2; in addition, since the button 2 no longer uses a glass panel, there is no need to worry about the problem of the glass panel being damaged due to excessive deformation of the button 2, so the button 2 no longer has the first dividing seam 271, and the connecting portion 24 extends directly to the third end; furthermore, since the button 2 no longer uses a glass panel, complex text or patterns cannot be laser engraved. In this embodiment, the button 2 only has a small hole to form the light-transmitting area 21.

[0169] It should be noted that Fig.26 The embodiment shown is compared to Figure 1-Figure 20 In the embodiment shown, the structures other than the key 2 are identical, therefore, Fig.26 The other structures of this embodiment are omitted and will not be described in detail here.

[0170] Existing smart switches are usually installed by screw fixing. However, the screw tightening process will cause the bottom shell to deform, and the deformation of the bottom shell may be transmitted to the circuit board and the electronic switch, causing them to be displaced, thereby affecting the normal triggering of the electronic switch. To avoid this problem, in the prior art, the circuit board carrying weak current is usually fixed on the middle shell. Since the middle shell will not be affected by the deformation of the bottom shell, the deformation of the bottom shell will not affect the circuit board. This solution generally uses two methods to fix the circuit board: the first is to fix the circuit board directly to the middle shell with screws; the second is to fix a guard plate on the lower side of the middle shell, and the circuit board is clamped and fixed between the guard plate and the middle shell. Although these two methods can isolate the impact of the deformation of the bottom shell to a certain extent, their installation and disassembly process is relatively cumbersome and it is difficult to improve assembly efficiency.

[0171] To solve the above problem, according to the third aspect of the present invention, Figure 1-Figure 26 As shown, a new intelligent switch 100 is proposed, which adopts a new fixing structure. The structure adopts a first housing 1 provided with a positioning portion 18 for positioning the circuit board 3, which can ensure stability while improving the convenience of disassembly and assembly.

[0172] Specific as Fig. 9 and Fig.10 As shown, the intelligent switch 100 comprises a bottom shell 4, a first shell 1, a circuit board 3 and a button 2; the first shell 1 is covered on the bottom shell 4; the circuit board 3 is installed on a side of the first shell 1 facing the bottom shell 4; the button 2 is arranged on a side of the first shell 1 facing away from the bottom shell 4, and the button 2 is movably connected to the first shell 1;

[0173] The circuit board 3 has a first circuit surface facing the button 2 and a second circuit surface facing away from the button 2. The first circuit surface is provided with an electronic switch 31. The button 2 can directly or indirectly trigger the electronic switch 31 under the action of pressing force.

[0174] According to an embodiment of the present disclosure, the button 2 can directly trigger the electronic switch 31, for example, directly through the hole provided on the first housing 1 to trigger the electronic switch 31 on the circuit board 3. The button 2 can also indirectly trigger the electronic switch 31, for example, by assisting in triggering the electronic switch 31 through some other structures. With respect to indirect triggering, a possible implementation method is provided in an embodiment of the disclosure, specifically: a triggering portion 142 is provided between the button 2 and the electronic switch 31, and the button 2 presses against the triggering portion 142 to trigger the electronic switch 31 through the triggering portion 142.

[0175] In addition, in a possible implementation, the first circuit surface of the circuit board 3 can be understood as Fig.19The upper surface of the circuit board 3, the second circuit surface can be understood as Fig.19 On this basis, the thickness direction of the circuit board 3 can be understood as Fig.19 In the vertical downward direction.

[0176] The first housing 1 is in contact with the first circuit surface. Figure 15-19 As shown, Fig.15 and Fig.16 For the perspective after flipping upside down, the first shell 1 is provided with a plurality of positioning portions 18 toward the circuit board 3, and the positioning portions 18 include a positioning unit, which protrudes out of the second circuit surface and abuts against the circuit board 3, so that when the pressing force applied to the button 2 is transmitted to the circuit board 3 through the electronic switch 31, the positioning unit locks the displacement of the circuit board 3 in the thickness direction, so that the electronic switch 31 is triggered.

[0177] Furthermore, during the installation of the circuit board 3, the first circuit surface abuts against the first housing 1, and the second circuit surface is abutted and supported by the positioning unit, thereby achieving stable positioning of the circuit board 3 between the first housing 1 and the positioning unit. During operation, when the button 2 is pressed, the pressing force is transmitted to the circuit board 3 through the electronic switch 31, and the displacement of the circuit board 3 in the thickness direction is locked by the upward positioning force provided by the positioning unit, ensuring reliable triggering of the electronic switch 31.

[0178] Through this structural design, the displacement of the circuit board 3 is firmly locked by the positioning portion 18, and reliable support and positioning of the circuit board 3 can be achieved without the need for screws, which greatly improves the convenience of disassembly and assembly of the circuit board 3.

[0179] It is worth mentioning that in the embodiment of the present disclosure, the design of the positioning unit protruding from the circuit board 3 ensures the stability of the positioning of the circuit board 3 and sufficient supporting effect, thereby avoiding unnecessary displacement of the circuit board 3 under the action of pressing force and ensuring that the switch can be successfully triggered.

[0180] Further, the circuit board 3 has a first connection end and a second connection end away from the first connection end, and the plurality of positioning portions 18 include at least one first positioning portion 182 and at least two second positioning portions 183; the first positioning portion 182 is arranged at a position corresponding to the first connection end, and the second positioning portion 183 is arranged at a position close to the second connection end; the first positioning portion 182 includes a first connecting arm 1821 extending from the first shell 1 and a first positioning unit 1822 arranged at the end of the first connecting arm 1821, and the second positioning portion 183 includes a second connecting arm 1831 extending from the first shell 1 and a second positioning unit 1832 arranged at the end of the second connecting arm 1831, and the first positioning unit 1822 and the second positioning unit 1832 are respectively abutted against the second circuit surface of the circuit board 3 to lock the displacement of the circuit board 3 in the thickness direction;

[0181] The rigidity of the first connecting arm 1821 is greater than the rigidity of the second connecting arm 1831, so that when the circuit board 3 is installed, the first connecting end can be first inserted between the first positioning unit 1822 and the first shell 1, and then the second connecting end is pressed toward the first shell 1. The second positioning unit 1832 is squeezed by the circuit board 3 to drive the second connecting arm 1831 to undergo elastic deformation, and then the circuit board 3 is stuck between the second positioning unit 1832 and the first shell 1.

[0182] Furthermore, the bottom shell 4 is provided with a receiving groove 41 , the circuit board 3 is received in the receiving groove 41 , and the second connecting arm 1831 is abutted by a side wall of the receiving groove 41 to enhance the anti-deformation capability of the second connecting arm 1831 .

[0183] Furthermore, a first guiding slope 44 is disposed on the upper edge of the accommodating groove 41 , a second guiding slope 1833 is disposed on the bottom of the second connecting arm 1831 , and the second guiding slope 1833 is disposed on a side of the second connecting arm 1831 away from the circuit board 3 .

[0184] In some embodiments, the circuit board 3 includes a first side edge and a second side edge arranged between the first connection end and the second connection end, and the first side edge and the second side edge are respectively located on both sides of the circuit board 3; the number of the second positioning portions 183 is two, and the second positioning units 1832 of the two second positioning portions 183 are respectively abutted against the first side edge and the second side edge.

[0185] Furthermore, the number of the first positioning portions 182 is two, and the first positioning units 1822 of the two first positioning portions 182 respectively abut against the first connecting end of the circuit board 3, and the width of the first connecting arm 1821 is greater than the width of the second connecting arm 1831, so that the rigidity of the first connecting arm 1821 is greater than the rigidity of the second connecting arm 1831.

[0186] In some embodiments, the electronic switch 31 is located on a connecting line of two second positioning portions 183 .

[0187] In some embodiments, the circuit board 3 is provided with a first positioning hole 38, and the first shell 1 is provided with a first positioning column 19, which is inserted into the first positioning hole 38 to lock the displacement of the circuit board 3 parallel to the first circuit surface.

[0188] Furthermore, the first positioning hole 38 is arranged at a position of the circuit board 3 close to the second connecting end.

[0189] In some embodiments, the circuit board 3 carries a high-voltage circuit and a low-voltage circuit, and the bottom shell 4 is provided with a receiving groove 41 , and the circuit board 3 is received in the receiving groove 41 .
