For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The technical solutions of the various embodiments can be combined with each other, but this 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 protection scope claimed by the present invention.

[0059] Smart switches typically feature illuminated text or patterns on the button surface. The panel contains LEDs and a light-diffusing shield. The light emitted by the LEDs is diffused by the shield before illuminating the button, causing the text or patterns on the button surface to glow. However, ultra-thin smart switches, due to their very thin panel, have insufficient space for light diffusion, resulting in poor light distribution. When the illuminated surface of the button is large, noticeable unevenness in the illuminated area becomes apparent.

[0060] To address the aforementioned problems, according to a first aspect of the present invention, a light-transmitting structure is provided, applicable not only to smart switches but also to other products with button panels. Please refer to [link / reference]. Figures 1-26 The light-transmitting structure provided by this invention will be explained in detail. For example... Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, where, Figure 9 for Figure 2 A vertical sectional view of part AA. Figure 10 for Figure 9 Enlarged view of part B, Figure 11 for Figure 10 A partially enlarged cross-sectional view of the CC portion. The light-transmitting structure includes a first housing 1, a button 2, and a circuit board 3. The button 2 is disposed on a first side of the first housing 1; the circuit board 3 is disposed on a second side of the first housing 1 opposite to the first side; the first housing 1 is provided with a light source space 111 and a reflection space 112 adjacent to the light source space 111; the button 2 has a light-transmitting area 21 positioned opposite to the reflection space 112; a light guide channel 113 is provided between the light source space 111 and the reflection space 112; the circuit board 3 has a light-emitting element 35 disposed inside the light source space 111; the light emitted by the light-emitting element 35 passes through the light guide channel 113 and illuminates the reflection space 112, then is reflected by the reflection space 112 to the light-transmitting area 21 of the button 2, and finally passes through the light-transmitting area 21. The light-transmitting area 21 can be a through hole or a hollowed-out text or pattern; light passing through the light-transmitting area 21 forms a light-emitting hole or text or pattern on the outer surface of the button 2.

[0061] The light-transmitting structure provided by this invention allows light emitted by the light-emitting element 35 to be reflected through the light guide channel 113 and the reflection space 112 to the light-transmitting area 21, avoiding direct light from the light-emitting element 35 to the light-transmitting area 21. The light achieves a uniform light effect during reflection. Furthermore, the horizontal expansion of the reflection space 112 does not increase the thickness of the first housing 1, allowing sufficient space for the light to achieve a better uniform light effect. This solves the problem of uneven light emission on the button 2 surface caused by insufficient uniform light space in the ultra-thin smart switch 100, enabling large-area light emission in the ultra-thin smart switch 100. "Ultra-thin" can be understood as: when the smart switch 100 is installed on a wall, the components of the smart switch 100 located outside the wall (i.e., the first housing 1 and the button 2) are very thin, thus making the smart switch 100 appear ultra-thin.

[0062] Wherein, the first side of the first housing 1 is Figure 9 The upper side of the first housing 1, the second side of the first housing 1 is Figure 9 The light source space 111 and the reflection space 112 can be spaces disposed inside the first housing 1, or spaces formed by the first housing 1 combined with other components. The light guide channel 113 can be a channel-shaped structure, or a through hole, notch, or other structure that allows light to pass through. The light-emitting element 35 can be an LED lamp or other electronic components capable of emitting light.

[0063] Furthermore, the first housing 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.

[0064] In one exemplary embodiment, the light reflected from the reflective space 112 illuminates the light-transmitting area 21, and the light passes through the light-transmitting area 21. In another exemplary embodiment, a light-diffusing sheet (not shown in the figure) is provided between the reflective space 112 and the light-transmitting area 21. The light reflected from the reflective space 112 is diffused by the light-diffusing sheet and then illuminates the light-transmitting area 21, and then passes through the light-transmitting area 21 to enhance the light-diffusing effect.

[0065] In one exemplary embodiment, the inner wall of the reflection space 112 is constructed with a frosted surface to allow light to be diffusely reflected within the reflection space 112, thereby enhancing the uniform light effect; in another exemplary embodiment, the inner wall of the reflection space 112 is constructed with a smooth surface to allow for higher light reflection brightness.

[0066] Furthermore, such as Figure 10As shown, the direction of the light source space 111 toward the reflection space 112 is designated as the first direction, and the direction of the reflection space 112 toward the light-transmitting area 21 is designated as the 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, light emitted from the light-emitting element 35 is prevented from directly shining from the light guide channel 113 onto the light-transmitting area 21. Furthermore, the light source space 111 and the reflection space 112 are arranged side by side along the first direction, reducing their stacking in the vertical direction and making the thickness of the first housing 1 thinner. The first and second directions have already been defined. Figure 10 The bid was successful.

[0067] In some embodiments, such as Figure 10 As shown, the reflection space 112 includes a first reflective surface facing the light source space 111, and the first reflective surface is inclined in the first direction. The first reflective surface is the surface that receives direct light from the light-emitting element 35. The first reflective surface is inclined to ensure sufficient light is reflected to the light-transmitting area 21, enhancing the brightness of the light-transmitting area 21. Furthermore, the angle between the first reflective surface and the first direction is greater than 45°, meaning the first reflective surface is more vertical, causing the light to undergo multiple reflections within the reflection space 112, resulting in better light uniformity. In an exemplary embodiment, the angle between the first reflective surface and the first direction is 60°.

[0068] Furthermore, such as Figure 7 , Figure 10 and Figure 11 As shown, the reflection space 112 is constructed as a horn-shaped structure with open upper and lower ends and a larger upper end than a smaller lower end. The circuit board 3 is placed on the lower end of the horn-shaped structure. The horn-shaped structure includes a first reflective surface, a second reflective surface opposite to the first reflective surface, and a third and a fourth reflective surface respectively disposed on both sides of the first reflective surface. The first, third, second, and fourth reflective surfaces surround each other to form the sidewall of the horn-shaped structure. The light guide channel 113 is opened on the second reflective surface. The direction of the reflection space 112 toward the light-transmitting area 21 is designated as the second direction. The first, third, and fourth reflective surfaces are inclined in the second direction. The inclination angle of the first reflective surface relative to the second direction is greater than the inclination angle of the third reflective surface and greater than the inclination angle of the fourth reflective surface, so as to ensure that enough light is reflected to the light-transmitting area 21 and enhance the brightness of the light-transmitting area 21. In an exemplary embodiment, the first reflective surface is tilted at an angle of 30° relative to the second direction, the third and fourth reflective surfaces are both tilted at an angle of 25° relative to the second direction, and the second reflective surface is tilted at an angle of 2° relative to the second direction.

[0069] Since the light-emitting element 35 is a point light source, its light intensity gradually decreases from the center to the periphery. Therefore, when light shines on the first reflective surface, the brightness at the center of the first reflective surface will be slightly higher than the brightness on both sides, causing uneven reflection of the first reflective surface. To solve this problem, in some embodiments, such as... Figure 11 , Figure 10 and Figure 7 As shown, the light guide channel 113 has a light-blocking part 114 positioned directly opposite the light-emitting element 35. The light-blocking part 114 blocks a portion of the light rays entering the reflection space 112 directly opposite the light-emitting element 35, thereby reducing the brightness of the light illuminating the center of the first reflective surface. This allows the light to be more evenly distributed across the first reflective surface, resulting in better uniform light distribution in the reflection space 112. Furthermore, during design, the width and height of the light-blocking part 114 can be tailored to the specific illumination effect to achieve a better uniform light distribution. In an exemplary embodiment, as... Figure 11 As shown, the bottom of the second reflective surface abuts against the circuit board 3, and the bottom of the second reflective surface has an elongated notch, which forms the light guide channel 113 with the circuit board 3; the light blocking part 114 extends from top to bottom on the second reflective surface, and the light blocking part 114 is constructed in a square shape. There is a light-transmitting gap between the bottom of the light blocking part 114 and the circuit board 3. The light blocking intensity can be adjusted by adjusting the height and width of the light blocking part 114, thereby achieving a better uniform light effect.

[0070] In some embodiments, such as Figure 10 and Figure 15 As shown, the light source space 111 is formed by the top wall and side wall of the light source, and the light guide channel 113 is opened in the side wall of the light source; the circuit board 3 is covered on the bottom of the light source space 111 to form a light source receiving cavity between the light source space 111 and the circuit board 3, and the light-emitting element 35 is housed in the light source receiving cavity, thereby preventing the light of the light-emitting element 35 from directly shining on the light-transmitting area 21 of the button 2, and preventing the light of the light-emitting element 35 from passing through the gap of the first housing 1.

[0071] Furthermore, such as Figure 10 and Figure 11 As shown, the surface of the circuit board 3 is white at the corresponding positions in the light source housing cavity and the reflection space 112 to avoid color distortion of the reflected light. In an exemplary embodiment, white ink is screen-printed on the surface of the circuit board 3 at the corresponding positions in the light source housing cavity and the reflection space 112 to achieve color change. In other embodiments, this color change can also be achieved by pasting a white film.

[0072] In some embodiments, such as Figures 2-6 andFigure 10 As shown, the button 2 includes a plastic button bracket 22 and a glass button panel 23. The button bracket 22 is rotatably connected to the first housing 1, and the button panel 23 is attached to the button bracket 22. A light-shielding layer covers the side of the button panel 23 facing the button bracket 22. The light-shielding layer is perforated to form a light-transmitting area 21. A light-transmitting hole 221 is formed on the button bracket 22 at a corresponding position in the light-transmitting area 21. Light reflected from the reflection space 112 passes through the light-transmitting hole 221 and illuminates the light-shielding layer, then passes through the light-transmitting area 21. The rotatable connection can be understood as a connection method that allows relative rotation, including shaft-hole rotatable connections, snap-fit ​​rotatable connections, etc. The light-shielding layer includes a color layer facing the button panel 23 and a black paint layer facing the button bracket 22. The color layer is used to give the button panel 23 its color, and the black paint layer is used for light shielding. The light-shielding layer is laser-engraved with hollowed-out text or patterns, which form the light-transmitting area 21. Light passes through the light-transmitting area 21 and forms luminous patterns or text on the button panel 23. The button panel 23 is made of AG frosted glass, which has a slight light-diffusing effect.

[0073] It is worth mentioning that existing smart switches generally use one-piece injection molding of plastic for their buttons, resulting in poor rigidity. When the button is thin, its deformation is large, which can easily lead to the inability to trigger the electronic switch. In this embodiment, button 2 adopts a structure that combines a plastic bracket with a glass panel. This gives button 2 both the ease of processing and shaping of plastic and the rigidity of glass. This allows button 2 to meet the connection function while having strong resistance to deformation. This also prevents button 2 from becoming too thin, which could lead to deformation and failure to trigger the electronic switch 31. The electronic switch 31 can be a micro switch, a tactile switch, a membrane switch, etc. In an exemplary embodiment, the electronic switch 31 is a micro switch 311.

[0074] Furthermore, the light-transmitting hole 221 is constructed as a square through hole, and the light-transmitting area 21 is located within the range of the light-transmitting hole 221. For example... Figure 10 and Figure 11 As shown, the size of the light-transmitting hole 221 is slightly larger than the size of the upper opening of the reflective space 112.

[0075] According to a second aspect of the invention, such as Figures 1-26As shown, a smart switch 100 is also provided, including the aforementioned light-transmitting structure and a bottom shell 4. The first housing 1 covers the bottom shell 4, and the bottom shell 4 is provided with a receiving groove 41, in which the circuit board 3 is received. The first housing 1 can be understood as the middle shell of the smart switch 100. When the smart switch 100 is installed on a wall, the first housing 1 is located outside the wall surface, with the button 2 covered on the front and the sides of the first housing 1 exposed outside the wall surface.

[0076] In this embodiment of the invention, the circuit board 3 is placed in the receiving groove 41 of the bottom shell 4, which avoids the circuit board 3 occupying the space of the first shell 1, making the first shell 1 thinner. Furthermore, the circuit board 3 is set in the receiving groove 41, so that the first shell 1 has enough space to design the above-mentioned light-transmitting structure while reducing its thickness, thereby realizing the design of the ultra-thin smart switch 100.

[0077] Furthermore, such as Figure 17 and Figure 18 As shown, the circuit board 3 carries both low-voltage and high-voltage circuits. The circuit board 3 includes a power module (not shown), a relay 32, a wireless communication module 33, a processing module 34, an electronic switch 31, and the light-emitting element 35. Placing these electronic components on the same circuit board 3 reduces the number of circuit boards 3, saves space, and allows the receiving groove 41 to accommodate the entire circuit section, thereby reducing the thickness of the smart switch 100's panel. The panel of the smart switch 100 can be understood as the portion located on the exterior of the wall when the smart switch 100 is installed on a wall.

[0078] Furthermore, the power module and relay 32 are disposed on the lower surface of the circuit board 3. The lower surface of the circuit board 3 also has a terminal block 36 for connecting the neutral wire, the live wire, and the control line for controlling the controlled device. The power module is connected to the neutral and live wires via the terminal block 36 to convert household AC power into low-voltage DC power, thereby supplying power to the low-voltage circuit. The relay 32 is electrically connected to the processing module 34. The processing module 34 controls the relay 32 to switch its on / off state in response to the triggering of the electronic switch 31. The relay 32 is connected to the controlled device via the terminal block 36. The relay 32 switches its on / off state to cut off or connect the power supply to the controlled device, thereby realizing the switching function.

[0079] Furthermore, such as Figure 17 As shown, the processing module 34 is integrated into the wireless communication module 33, which is disposed on the upper surface of the circuit board 3 to enhance the signal strength of the wireless communication module 33. Furthermore, the wireless communication module 33 has a communication antenna 331, and the circuit board 3 has a communication notch 37 at the position corresponding to the communication antenna 331 to prevent the circuit board 3 from generating a shielding effect.

[0080] Furthermore, such as Figure 18 As shown, the sidewall of the receiving groove 41 is provided with an avoidance groove 46 at the corresponding position of the wireless communication module 33. The avoidance groove 46 is used to make room for the wireless communication module 33 to avoid interference between the wireless communication module 33 and the bottom shell 4.

[0081] Existing smart switches with backlit buttons are prone to light leakage due to gaps between buttons and between buttons and the inner shell. This is especially true for ultra-thin smart switches, where the buttons and inner shell are thin and there is not enough space to design a light-shielding structure, making them extremely prone to light leakage.

[0082] To address the light leakage issue in smart switches, in some embodiments, such as Figure 3 , Figure 7 , Figure 10 as well as Figure 11 As shown, the first housing 1 is provided with a light transmission structure 11, and the button 2 is provided with a light-transmitting area 21 at a position opposite to the light transmission structure 11. The light emitted by the light-emitting element 35 is transmitted through the light transmission structure 11 to the light-transmitting area 21 of the button 2, and then passes through the light-transmitting area 21. The button 2 is provided with a light-shielding part 223 protruding towards the first housing 1. The light-shielding part 223 surrounds at least two sides of the light-transmitting area 21. The first side of the first housing 1 is provided with a first recess 121, and the light-shielding part 223 is at least partially sunk into the first recess 121.

[0083] By staggering the light-shielding part 223 and the first recess 121 in the vertical direction, light cannot pass through the side of the button 2, thus avoiding light leakage. The light-shielding part 223 can be a light-shielding rib, a light-shielding plate, or other structures. The fact that the light-shielding part 223 is at least partially recessed into the first recess 121 can be understood as the light-shielding part 223 and the first recess 121 overlapping in the thickness direction, thereby preventing light from passing through the gap between the light-shielding part 223 and the first recess 121.

[0084] The light transmission structure 11 includes the light source space 111, reflection space 112, and light guide channel 113 described above, and the light-emitting element 35 is disposed within the light source space 111. The light transmission includes direct light transmission and reflection. The technical details of the light source space 111, reflection space 112, light guide channel 113, light-transmitting area 21, and light-emitting element 35 have been described in detail above and will not be repeated here.

[0085] In addition, thanks to the fact that the circuit board 3 is housed in the receiving 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 has enough space to set the first recess 121.

[0086] When the smart switch 100 is a multi-button smart switch 100, the button 2 includes multiple button units 20, and electronic switches 31 are arranged one-to-one with the button units 20. Each button unit 20 can be pressed to trigger the corresponding electronic switch 31. A second dividing slit 272 exists between each button unit 20, and the second dividing slit 272 is the main area where light leaks from the button 2. To prevent light leakage through the second dividing slit 272, in this embodiment of the invention, as follows... Figure 3 , Figure 7 as well as Figure 11 As shown, a second recess 122 is provided on the first side of the first housing 1 in the area corresponding to the first protrusion 13. The height of the light-shielding part 223 at the corresponding position of the second recess 122 is higher than the height of the light-shielding part 223 at other positions. The light-shielding part 223 near the second dividing seam 272 is located in the second recess 122, so that the light-shielding parts 223 on both sides of the second dividing seam 272 can be embedded deeper into the first housing 1 to prevent light leakage from the gap between the button units 20.

[0087] Furthermore, such as Figure 15 and Figure 10 As shown, a first protrusion 13 is provided on the second side of the first housing 1. The first protrusion 13 is embedded in the bottom housing 4. The first protrusion 13 uses the space of the bottom housing 4 to provide space for the second recess 122, so as to ensure the light-blocking effect without increasing the thickness of the first housing 1.

[0088] Furthermore, such as Figures 3-7 as well as Figure 10 and Figure 11 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 housing 1, and the button panel 23 is attached to the button bracket 22. The light-shielding part 223 is disposed on the button bracket 22, and the projection of the button bracket 22 onto the first housing 1 is contained within the first recess 121. When the button 2 is pressed, the button bracket 22 can be embedded in the first recess 121, so that when reserving the pressing gap, the thickness of the button bracket 22 does not need to be taken into account; only the gap between the button panel 23 and the first housing 1 needs to be considered, thereby reducing the pressing gap of the button 2 and making the overall thickness of the panel thinner.

[0089] Furthermore, such as Figure 6 and Figure 21 As shown, where, Figure 6 This is a schematic diagram of the button bracket 22 of the three-button smart switch 100. Figure 21This is a schematic diagram of the structure of a two-button smart switch 100. The light-shielding part 223 includes a first light-shielding rib 2231, a second light-shielding rib 2232, and a third light-shielding rib 2233. The first light-shielding rib 2231, the second light-shielding rib 2232, and the third light-shielding rib 2233 surround three sides of the light-transmitting hole 221 to prevent light from passing through the side and tail of the button 2. Further, the first light-shielding rib 2231 and the second light-shielding rib 2232 are respectively located on both sides of the light-transmitting hole 221, and the third light-shielding rib 2233 is located on the side of the light-transmitting hole 221 away from the rotatable connection. Since the closer the light-shielding rib is to the light source, the better the light-shielding effect. In one embodiment, the distance between the third light-shielding rib 2233 and the light-transmitting hole 221 is less than 4mm, making the light-shielding effect of the third light-shielding rib 2233 even better. Furthermore, the first light-blocking rib 2231, the second light-blocking rib 2232, and the third light-blocking rib 2233 are connected as one unit to form a tight light-blocking barrier and improve the light-blocking effect.

[0090] In some embodiments, such as Figure 7 and Figure 3 As shown, the first housing 1 has a partial recess 123 at the position corresponding to the light-shielding part 223. The partial recess 123 is located within the first recess 121. When the button 2 is pressed, the light-shielding part 223 sinks into the partial recess 123. The partial recess 123 is used to provide downward space for the light-shielding part 223, thereby reducing the thickness of the panel of the smart switch 100.

[0091] In some embodiments, the button bracket 22 is made of black plastic so that the button bracket 22 has a light-absorbing function and reduces light leakage caused by light reflection from the button bracket 22.

[0092] In some embodiments, such as Figure 7 , Figure 10 and Figure 11 As shown, a light-shielding enclosure 115 protrudes from the first side of the first housing 1, surrounding the light outlet of the light transmission structure 11; the light-shielding part 223 surrounds the outside of the light-shielding enclosure 115. The light outlet of the light transmission structure 11 is the upper opening of the reflection space 112. The light-shielding enclosure 115 protrudes from the upper surface of the first housing 1, while the light-shielding part 223 protrudes from the lower surface of the button bracket 22. The light-shielding enclosure 115 and the light-shielding part 223 form an alternating structure to enhance the light-shielding effect.

[0093] Existing smart switches generally include a button, an electronic switch, a reset component, and a housing. Pressing the button triggers the corresponding electronic switch and resets upon depressing. When the pressure is released, the button springs back up under the reset force of the reset component. To ensure that all buttons spring back to the same height, a limit hook is typically provided at the end of the button. This limit hook engages with the housing to limit the button's upward movement. The housing has a locking position that fits the limit hook. The limit hook and locking position occupy a significant amount of space, resulting in a relatively thick button and housing.

[0094] To address the issue of thick buttons and a thick inner shell, in this embodiment of the invention, the button 2 has a self-limiting function, enabling it to spring upwards to its extreme position without being limited by a limiting hook. Specifically, as shown... Figure 3 and Figure 9 As shown, the smart switch 100 further includes a reset member 14, which abuts against the button 2 to provide a reset force; the button 2 is rotatably connected to the first housing 1, and the rotatably connected shaft is set as a first shaft 151. The button 2 has a first end near the first shaft 151 and a second end away from the first shaft 151; as shown Figure 14 , Figure 13 and Figure 9 As shown, the direction from the first end to the second end is defined as the fourth direction.

[0095] In the fourth direction, the reset member 14 is disposed between the first rotating shaft 151 and the second end. A limiting distance L1 exists between the first rotating shaft 151 and the first end, such that when the button 2 is not pressed, the first end of the button 2 abuts against the first housing 1. This generates a limiting constraint on the second end, restricting its movement away from the first housing 1. This allows the button 2 to generate an upper limit through its own abutment without the need for a similar limiting hook structure, simplifying the structure of the button 2 and the first housing 1 and reducing its thickness. When the button 2 and the first housing 1 are connected via a shaft-hole type, the first rotating shaft 151 can be understood as a solid rotating shaft. When the connection between the button 2 and the first housing 1 is not a shaft-hole type, the first rotating shaft 151 can also be understood as the axis of rotation for the button 2. The fourth direction is opposite to the first direction described above.

[0096] like Figure 14As shown, button 2 rotates based on the first rotating shaft 151. When button 2 is not pressed, the abutting force generated by the first end of button 2 abutting against the first housing 1 generates an abutting torque relative to the first rotating shaft 151. This abutting torque is balanced with the reset torque generated by the elastic force of the reset member 14. The lever arm of the reset torque is L3. Obviously, the lever arm of the abutting torque is the limiting generation distance L1. If L1 is too short, the abutting torque will be insufficient, resulting in a weak limiting constraint and inconsistent heights at the second ends of each button unit 20. If L1 is too long, the first rotating shaft 151 will be too close to the second end, reducing the pressable area of ​​button 2 and resulting in a poor pressing feel. In this embodiment, the distance between the first end and the second end is set to L2, and the limiting generation distance L1 satisfies the condition: 0.15≤L1 / L2≤0.4, so as to improve the pressing feel of button 2 while ensuring a strong limiting constraint.

[0097] Furthermore, such as Figure 3 and Figure 10 As shown, the electronic switch 31 is disposed on the side of the first housing 1 opposite to the button 2; the button 2 has a driving part 224 disposed at the position corresponding to the electronic switch 31, and the driving part 224 directly or indirectly triggers the electronic switch 31; wherein, directly or indirectly triggering the electronic switch 31 can be understood as the driving part 224 directly triggering the electronic switch 31, or indirectly triggering the electronic switch 31 through other structures. In one embodiment, a trigger part 142 is disposed between the driving part 224 and the electronic switch 31, and the driving part 224 presses against the trigger part 142 to trigger the electronic switch 31 through the trigger part 142. Figure 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 button 2 will increase, and the deformation of the button 2 will increase, resulting in a larger pressing gap for the button 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, pressing the button panel 23 will be more difficult, affecting the pressing feel. Therefore, 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 as to ensure the pressing feel of the button 2 while controlling the pressing gap of the button 2.

[0098] Furthermore, such as Figure 9 and Figure 10 As shown, the electronic switch 31 is located between the circuit board 3 and the first housing 1, with the first housing 1 covering the bottom housing 4. Both the circuit board 3 and the electronic switch 31 are accommodated in the receiving groove 41. This ensures that the circuit board 3 and the electronic switch 31 do not occupy the thickness of the smart switch 100 located outside the wall, allowing the switch panel to be thinner.

[0099] Furthermore, such as Figure 3 , Figure 12 and Figure 14 As shown, the first housing 1 is provided with the first rotating shaft 151, which is a solid shaft. The button 2 is provided with a first claw 25 adapted to the first rotating shaft 151. The first claw 25 is engaged with the first rotating shaft 151 to realize the rotational connection between the button 2 and the first housing 1. The first rotating shaft 151 and the first claw 25 are both located in the area of ​​the receiving groove 41 projected onto the first housing 1, so that when the first claw 25 is engaged with the first rotating shaft 151, the first claw 25 can use the space of the receiving groove 41, thereby allowing the structure of the first housing 1 related to the first rotating shaft 151 to sink into the receiving groove 41, which is beneficial to reducing the thickness of the smart switch 100 located outside the wall.

[0100] Furthermore, such as Figure 3 , Figure 16 and Figure 14 As shown, the first protrusion 13 is embedded in the bottom shell 4, and the circuit board 3 is mounted on the first protrusion 13; the second recess 122 is disposed in the corresponding area of ​​the first protrusion 13, and the first rotating shaft 151 is disposed in the second recess 122. The corresponding area of ​​the first protrusion 13 can be understood as the shape and size of the first protrusion 13 corresponding to the second recess 122, with the second recess 122 recessed downwards to allow the first shell 1 to protrude downwards to form the first protrusion 13. The first rotating shaft 151 is disposed in the second recess 122 so that the structure of the first shell 1 associated with the first rotating shaft 151 can be recessed into the receiving groove 41.

[0101] In some embodiments, such as Figure 3 and Figure 13As shown, the button 2 includes multiple button units 20. The number and position of the electronic switches 31 correspond to the button units 20. Each button unit 20 triggers its corresponding electronic switch 31. The button units 20 are connected to each other via connecting parts 24. The connection of the button units 20 into a single unit via connecting parts 24 has the following advantages: it ensures that the gap width between the button units 20 remains consistent; it facilitates the assembly of the button 2 onto the first housing 1, improving assembly efficiency; since the circuit board 3 carries a high-voltage circuit, disassembling the first housing 1 during the installation of the smart switch 100 would pose a risk of electric shock. Therefore, only the button 2 can be disassembled during the installation of the smart switch 100. The connection of the button units 20 into a single unit via connecting parts 24 facilitates the overall disassembly of the button 2, improving 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 a similar limiting hook structure, making it more convenient for users to disassemble the button 2, further improving the installation efficiency of the smart switch 100.

[0102] However, the fact that the button unit 20 is connected as a whole through the connecting part 24 will bring another problem to the disassembly of the button 2: the button 2 is generally connected to the first housing 1 through multiple first claws 25. If each first claw 25 is disassembled one by one, some first claws 25 will be in a locked state while other claws will be in a disengaged state. In this case, the connecting part 24 will be greatly twisted and deformed, thereby damaging the connecting part 24.

[0103] To solve this problem, such as Figure 3 , Figure 12 as well as Figure 13As shown, there are two first claws 25, respectively disposed on both sides of the button 2; the button 2 has at least one first hook 26 between the two first claws 25, and the first housing 1 is provided with a second hook 152 adapted to the first hook 26. The first hook 26 engages with the second hook 152, and the first hook 26 is located on the line connecting the two first claws 25; wherein, the engagement force between the first claw 25 and the first rotating shaft 151 is greater than the engagement force between the first hook 26 and the second hook 152, thus forming a strong and weak connection method. 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 disengages, the first hook 26 near the first claw 25 will also automatically disengage, avoiding large twisting deformation of the connecting part 24 and protecting the connecting part 24 from damage. In addition, when both first claws 25 disengage, the first hook 26 will automatically disengage, making it easy to remove 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 amount of deformation per unit length, thereby reducing the twisting deformation of the connecting part 24 and preventing damage to the connecting part 24.

[0104] It is worth mentioning that the second latch 152 provides downward constraint to the button 2. When both sides of the button 2 are pressed, the second latch 152 can prevent the middle part of the button 2 from arching upward, thereby increasing the constraint on the button unit 20 and preventing the electronic switch 31 from failing to activate. Furthermore, as... Figure 13 As shown, the second hook 152 protrudes from the first housing 1, enabling it to support the button 2. When the middle part of the button 2 is pressed, the second hook 152 prevents the middle part of the button 2 from being pressed into a depression. In summary, the second hook 152 can both constrain the button 2 to arch upwards and prevent it from sinking downwards, similar to the function of the first rotating shaft 151. However, the locking force of the first hook 26 is weaker than that of the first claw 25. The second hook 152 and the first hook 26 cooperate to form a constraint similar to a rotating pair, enhancing the stability of the rotational connection between the button 2 and the first housing 1.

[0105] Furthermore, the first latch 26 is located on the line connecting the two first latches 25 to prevent the first latch 26 from interfering with the rotation of the button 2. A latch protrusion is provided at the end of the first latch 26, the latch protruding laterally from the first latch 26. Figure 14From the perspective of the view, when the button 2 is installed on the first housing 1, the end of the hook protrusion is exactly on a straight line with the center position of the first rotating shaft 151, so as to ensure that the first hook 26 can always constrain the button 2 to arch upward during the rotation of the button 2, and the first hook 26 will not interfere with the rotation of the button 2.

[0106] In some embodiments, such as Figure 18 As shown, the bottom shell 4 has two first countersunk holes 42, which can accommodate first screws (not shown in the figure). The bottom shell 4 is installed externally using the first screws. The first housing 1 has a first through hole 161 at the corresponding position of the first countersunk holes 42. 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 housing 1. Further, the bottom shell 4 has second countersunk holes 45 at its four corners, which can accommodate second screws (not shown in the figure). The bottom shell 4 is installed externally using the second screws. The first housing 1 has a second through hole 162 at the corresponding position of the second countersunk holes 45, which is used to accommodate the nut of the second screw. The first screw is suitable for connecting a concealed box, and the second screw is suitable for connecting wood veneer, cabinets, desktops, etc.

[0107] like Figure 20 As shown, a protrusion 43 is provided on the side of the bottom shell 4 away from the button 2 at the position corresponding to the first countersunk hole 42. The protrusion 43 ensures that the sidewall of the first countersunk hole 42 does 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 on the upper surface of the bottom shell 4, thereby reducing the volume of the nut in the first housing 1 and avoiding interference between the first housing 1 and the nut of the first screw.

[0108] In some embodiments, such as Figure 3 and Figure 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 drive portion 224 and the electronic switch 31. The drive 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 drive 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.

[0109] In some embodiments, such as Figure 3 and Figure 13As shown, the button 2 includes a button bracket 22 and a button panel 23 fixedly connected to the button bracket 22. The button bracket 22 is rotatably connected to the first housing 1. The button bracket 22 has an abutting protrusion 222 near the first end, facing the first housing 1. The abutting protrusion 222 abuts against the first housing 1 to restrict the movement of the second end of the button 2 away from the first housing 1. In this embodiment, the button 2 abuts against the first housing 1 via the abutting protrusion 222 to achieve second-end positioning. Compared to the button 2 abutting against the first housing 1 via a plane or edge, the height of the abutting protrusion 222 is easier to adjust and its dimensional accuracy is easier to control. Researchers can adjust the positioning of the second end of the button 2 by adjusting the height of the abutting protrusion 222, thereby obtaining the optimal height of the abutting protrusion 222 through multiple experiments, achieving precise control of the second-end positioning. Furthermore, the abutting protrusion 222 is located at the end of the first end of the button bracket 22.

[0110] Existing smart switches often exhibit uneven gaps between buttons when there are more than two buttons. To address this, researchers designed a one-piece button, where all buttons are integrated during manufacturing, ensuring consistent gap width. However, these one-piece buttons are typically made of plastic through injection molding, resulting in poor rigidity. When the button is thin, its deformation is significant, potentially causing the electronic switch to fail to activate. Current technology addresses this by increasing the button's thickness to improve its resistance to deformation. However, increasing the button thickness not only hinders the reduction of the switch panel's thickness but also creates a linkage effect between the buttons, causing the electronic switch to be triggered by this linkage.

[0111] To solve the above problems, in the embodiments of the present invention, such as Figures 3-6 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 housing 1, and the button bracket 22 includes multiple bracket units 225, which are connected together by a connecting part 24; the number and position of the electronic switches 31 correspond to the bracket units 225, and each bracket unit 225 triggers the corresponding electronic switch 31; wherein, the button panel 23 includes multiple panel units 231, which are fixedly connected to the bracket units 225 one by one, and the rigidity of the panel units 231 is greater than that of the bracket units 225.

[0112] In this embodiment, the panel unit 231 and the support unit 225 are fixedly connected as a whole, which improves the deformation resistance of the support unit 225 and avoids the situation where the deformation is too large and the electronic switch 31 cannot be triggered. At the same time, since the panel unit 231 has high rigidity, the thickness can be reduced while ensuring small deformation, thereby reducing the overall thickness of the button 2. Furthermore, since the connecting part 24 and the support unit 225 are integrated, the rigidity of the connecting part 24 and the support unit 225 is low, which preserves the flexibility of the connecting part 24, thereby reducing the linkage between the support units 225 and preventing the electronic switch 31 from being triggered by the button support 22.

[0113] The linkage triggering can be understood as follows: when a bracket unit 225 is pressed and triggers the corresponding electronic switch 31, another bracket unit 225 adjacent to that bracket unit 225 is linked, causing the adjacent electronic switch 31 to be falsely triggered. The bracket unit 225 can trigger the electronic switch 31 by directly contacting it or indirectly by driving other components. 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 high rigidity, while 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 from plastic, and the panel unit 231 is constructed as an AG frosted glass sheet. The connection method for fixing the panel unit 231 to the bracket unit 225 can be adhesive, snap-fit, riveting, or other connection methods. In one embodiment, the panel unit 231 is adhesively attached to the bracket unit 225.

[0114] Furthermore, such as Figure 6 As shown, the button bracket 22 has a third end near the first rotating shaft 151 and a fourth end away from the first rotating shaft 151. The direction from the third end to the fourth end is designated as a fifth direction. In this 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 button 2 is to the first rotating shaft 151, the smaller its rotation amplitude. In this embodiment, the first rotating shaft 151 is positioned 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 minimized. Correspondingly, the deformation of the connecting portion 24 is minimized, thereby reducing the linkage effect between adjacent bracket units 225 and preventing the electronic switch 31 from being triggered by the button bracket 22. The third end of the button bracket 22 corresponds to the first end of the button 2, and the fourth end of the button bracket 22 corresponds to the second end of the button 2.

[0115] It is worth noting that if the deformation of the connecting part 24 is too large, the part where the support unit 225 is connected to the connecting part 24 will also deform along with the connecting part 24. Since the button panel 23 is relatively rigid and not easily deformed, this will inevitably lead to a separation force between the button support 22 and the button panel 23, causing the button panel 23 to detach or be damaged. In this embodiment, the first rotating shaft 151 is set at the corresponding position of the connecting part 24, minimizing the deformation of the connecting part 24 and preventing the button panel 23 from detaching or being damaged. The fifth direction is the same as the fourth direction described above.

[0116] In existing integrated buttons, the connecting part is generally located at the end of the button. According to the lever principle, the farther the button 2 is from the first pivot 151, the greater its rotation amplitude. Correspondingly, the deformation of the connecting part 24 will also be greater. As mentioned above, excessive deformation of the connecting part 24 will lead to a significant linkage effect between adjacent support units 225 and may easily cause the button panel 23 to detach or be damaged. To avoid excessive deformation of the connecting part 24, in this embodiment, such as... Figure 4 As shown, two adjacent support units 225 are separated by a first dividing slit 271 and a second dividing slit 272. The first dividing slit 271 extends from the connecting portion 24 to the third end, and the second dividing slit 272 extends from the connecting portion 24 to the fourth end. That is, in the integrated button 2 provided in this embodiment, the connecting portion 24 is not located at the end of the button 2, avoiding excessive deformation of the connecting portion 24 caused by excessive rotation of the end of the button 2, thereby weakening the linkage effect between the support units 225 and preventing the button panel 23 from detaching or being damaged.

[0117] If the tail end of button 2 is pressed, the tail end of button 2 is subjected to downward pressing force, button 2 is subjected to downward restraining force at the corresponding position of the first rotating shaft 151, and button 2 is subjected to upward elastic force at the corresponding position of the reset member 14. If the distance between the position of the first rotating shaft 151 and the tail end of button 2 is too large, it will cause the deformation of button 2 to be too large, which may easily lead to the inability to trigger the electronic switch 31. Therefore, in this embodiment, if Figure 4 As shown, in the fifth direction, the length of the first dividing slit 271 is L4, and the length of the button bracket 22 is L5. L4 and L5 satisfy the relationship: L4 / L5≥0.1, so that the position of the connecting part 24 and the first rotating shaft 151 is 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 caused by the button 2 being pressed, and avoiding the situation where the electronic switch 31 cannot be triggered.

[0118] Furthermore, such as Figure 4As shown, in the fifth direction, the length of the connecting portion 24 is L6. If L6 is too short, the connection strength of the connecting portion 24 will be low, resulting in a loose connection between the button units 20. If L6 is too long, the deformation of the connecting portion 24 will be large, posing a risk of the button panel 23 delaminating or being damaged, and the linkage effect between the support units 225 will be strong. Therefore, in this embodiment, L6 satisfies the relationship: 0.1≤L6 / L5≤0.3, so that the connecting portion 24 has a small deformation while ensuring connection strength.

[0119] Furthermore, such as Figure 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 this sixth direction, the thickness of the connecting part 24 is d1, and d1 satisfies the condition: 1.2mm ≤ d1 ≤ 2mm. This ensures that the connecting part 24 has a certain degree of flexibility while maintaining connection strength, thereby reducing the linkage effect between the bracket units 225. The sixth direction is... Figure 12 The vertical downward direction in the middle.

[0120] In some embodiments, such as Figure 12 As shown, the connecting part 24 protrudes from the side of the button bracket 22 facing the first housing 1, and the connecting part 24 is recessed in the side of the button bracket 22 away from the first housing 1. Thus, the cross-section of the connecting part 24 presents a downwardly concave U-shape. Compared with the direct connection type connecting part 24, this embodiment adopts a U-shaped connecting part 24, which indirectly increases the width of the connecting part 24, thereby increasing the flexibility of the connecting part 24 and preventing the connecting part 24 from causing deformation of the bracket unit 225, which could lead to the button panel 23 delaminating or being damaged.

[0121] In some embodiments, such as Figure 5 , Figure 3 as well as Figure 10 As shown, in the fifth direction, the length of the button panel 23 is greater than the length of the button bracket 22; the first housing 1 is provided with the first recess 121. When the panel unit 231 is pressed, the fourth end of the corresponding bracket unit 225 is embedded in the first recess 121. This is equivalent to the button 2 having only the button panel 23 above the first housing 1, while the button bracket 22 is recessed into the first housing 1. This eliminates the need for the entire button 2 to be positioned above the first housing 1, thus reducing the overall thickness of the switch panel. Thanks to the greater rigidity of the button panel 23, it can be made very thin, ultimately presenting the visual effect of an ultra-thin button 2.

[0122] Furthermore, since the support unit 225 sinks into the first recess 121 when pressed, the thickness of the support unit 225 does not need to be taken into account when reserving the pressing gap. Only the gap between the button panel 23 and the first housing 1 needs to be considered, so that the pressing gap of the button 2 can be reduced and the overall thickness of the panel is thinner.

[0123] In some embodiments, such as Figure 9 , Figure 14 and Figure 13 As shown, the reset member 14 abuts against the button bracket 22 to provide a reset force. When the button bracket 22 is not pressed, the third end of the button bracket 22 abuts against the first housing 1 to restrict the fourth end of the button bracket 22 from moving away from the first housing 1. This allows the button 2 to achieve an upper limit position through its own abutment without the need for a structure similar to a limiting hook, which is beneficial for reducing the thickness of the button 2 and the first housing 1. The principle and technical details of the button 2's self-limiting position have been described in detail above and will not be repeated here.

[0124] In some embodiments, such as Figure 3 and Figure 9 As shown, the first housing 1 covers the bottom housing 4, and the circuit board 3 is accommodated in the accommodating groove 41 of the bottom housing 4. The circuit board 3 carries both low-voltage and high-voltage circuits, and the button 2 covers the first through hole 161 of the first housing 1. The circuit board 3 is accommodated in the accommodating groove, which avoids the circuit board 3 occupying space in the first housing 1, making the first housing 1 thinner. Since the circuit board 3 carries high-voltage circuits, disassembling the first housing 1 during the installation of the smart switch 100 would pose a risk of electric shock. Therefore, during the installation of the smart switch 100, only the button 2 can be removed to operate the mounting screws. The bracket unit 225, connected as a whole by the connecting part 24, facilitates the complete removal of the button 2, improving the installation efficiency of the smart switch 100.

[0125] Most smart switches on the market use either tactile switches or micro switches 311. The internal structure of the micro switch 311 is relatively complex, such as... Figure 25 The diagram shows the structure of a micro switch 311. The micro switch 311 includes a protective housing 3111, a drive rod 3112, a contact system, and a spring system 3113. When the downward stroke of the drive rod 3112 exceeds its limit, it can easily damage the spring system 3113. Commercially available smart switches typically use a button to directly trigger the micro switch 311. The button extends a trigger rod that contacts the micro switch 311. Because the trigger rod is thin, the contact area with the micro switch 311 is very small. When the button is pressed down, the pressure generated by the trigger rod is relatively large, which can easily push the drive rod 3112 beyond its travel, causing damage to the micro switch 311.

[0126] To address the issue of the micro switch 311 being easily damaged, in this embodiment of the invention, as follows: Figure 10 and Figure 25 As shown, the electronic switch 31 is a micro switch 311, which includes a protective shell 3111 and a drive rod 3112 that can extend and retract relative to the protective shell 3111. The button 2 presses the drive rod 3112 of the micro switch 311 through the trigger part 142, and the drive rod 3112 is pressed and generates a retraction movement to trigger the micro switch 311.

[0127] Among them, such as Figure 10 , Figure 7 and Figure 8 As shown, Figure 8 This is a schematic diagram showing the position and area relationship between the trigger part 142 and the micro switch 311. The trigger part 142 has a first surface, and the trigger part 142 drives the drive rod 3112 through the first surface. The first surface covers at least a specified area of ​​the upper surface of the protective shell 3111. The specified area is set such that when the first surface drives the drive rod 3112 to retract into 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 restricting the trigger part 142 and the button 2 from continuing to press.

[0128] In this embodiment, button 2 presses drive rod 3112 via trigger part 142. Since the first surface covers at least a specified area of ​​the upper surface of protective shell 3111, when the first surface abuts against protective shell 3111, the contact area between the first surface and protective shell 3111 is large, and the contact pressure is small, thus preventing protective shell 3111 from being crushed by trigger part 142. Furthermore, trigger part 142 is supported by protective shell 3111, preventing drive rod 3112 from being pressed beyond its limit stroke, thus protecting the internal structure of micro switch 311 from damage.

[0129] The first surface can be a plane or a curved surface. In this embodiment, the first surface is... Figure 10 The lower surface of the trigger part 142. The retraction of the drive rod 3112 into the protective shell 3111 can be understood as the drive rod 3112 moving to a position where it does not protrude from the upper surface of the protective shell 3111.

[0130] Furthermore, it is worth noting that existing smart switches require a lower limit for button pressing. This lower limit is typically provided by the first housing, while the electronic switch is usually mounted on a circuit board, which is located in either the first or bottom housing. This results in a relatively long dimensional chain between the button and the electronic switch, which can easily lead to accumulated errors. Ultimately, this can result in situations where the button reaches its lower limit position before the electronic switch is triggered. In this embodiment, the protective housing 3111 of the micro switch 311 supports the button 2 via the trigger part 142. The lower limit of the button 2 is provided by the protective housing 3111 of the micro switch 311. The dimensional chain between the micro switch 311 and the button 2 is extremely short, making the lower limit of the button 2 more precise. Moreover, when the trigger part 142 abuts against the protective housing 3111, the micro switch 311 is already triggered. That is, when the button 2 reaches its lower limit position, the micro switch 311 will inevitably be triggered, preventing situations where the button 2 reaches its lower limit position before the micro switch 311 is triggered.

[0131] Furthermore, the designated area is 20% of the area of ​​the upper surface of the protective shell 3111, so as to ensure that the contact area between the first surface and the protective shell 3111 is large enough, thereby making the contact pressure small enough to ensure that the protective shell 3111 will not deform under the pressure of the first surface, and can stably support the trigger part 142 to avoid damage to the micro switch 311.

[0132] Furthermore, such as Figure 10 and Figure 8 As shown, the trigger part 142 is constructed as a plate-like structure, and the first surface is the entire surface of the trigger part 142 facing the micro switch 311; thereby making the first surface as large as possible, and the first surface has no protruding structure, so as to ensure that the first surface can cover at least 20% of the upper surface area of ​​the protective shell 3111, and avoid damage to the micro switch 311.

[0133] Furthermore, such as Figures 7-10 As shown, the first housing 1 extends to provide the elastic arm 141, and the trigger part 142 is integrally formed at the free end of the elastic arm 141.

[0134] Furthermore, such as Figure 8 As shown, the end of the trigger part 142 away from the elastic arm 141 is semi-circular, and the drive rod 3112 of the micro switch 311 is located near the center of the semi-circular shape to reduce the pressing stress generated by the trigger part 142.

[0135] In some embodiments, such as Figure 7 and Figure 10As shown, the elastic arm 141 and the trigger part 142 are combined to form a reset member 14, which provides a reset force for the button 2. The trigger part 142 can protect the micro switch 311 from damage, cooperate with the protective shell 3111 to provide a lower limit for the button 2, and also provide a reset force. Moreover, the structure is simple and does not occupy the thickness of the first shell 1, thus providing structural support for the thinning of the first shell 1.

[0136] Furthermore, the trigger portion 142 is provided with a support protrusion 143 facing the button 2. 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 portion 142 provides a pre-tightening force to prevent the button 2 from becoming loose. Moreover, by adjusting the height of the support protrusion 143, the magnitude of the pre-tightening force and the reset force provided by the trigger portion 142 can be adjusted, thereby improving the tactile feel of pressing the button 2.

[0137] During the pressing process, button 2 and the support protrusion 143 will experience relative horizontal movement, resulting in friction and a stiff pressing feel. Therefore, as follows... Figure 3 and Figure 10 As shown, the button 2 is provided with a driving part 224 at the corresponding position of the support protrusion 143, and the button 2 abuts against the support protrusion 143 through the driving part 224; both the driving part 224 and the support protrusion 143 are constructed as strip-shaped protrusions, and the two are arranged in a crisscross pattern so that the relative movement between the driving part 224 and the support protrusion 143 will not interfere, and avoid the pressing feel being sticky.

[0138] In some embodiments, such as Figure 10 and Figure 15 As shown, where, Figure 15 This is the view after the first housing 1 is flipped up and down. On the side of the first housing 1 facing the micro switch 311, a third recess 17 is provided at the position corresponding to the micro switch 311. The micro switch 311 is embedded in the third recess 17 so that the micro switch 311 is closer to the trigger part 142, thereby enabling the micro switch 311 to be successfully triggered without the need for a protruding structure on the lower surface of the trigger part 142.

[0139] In some embodiments, such as Figure 9 and Figure 10As shown, the first housing 1 covers the bottom housing 4, the circuit board 3 is mounted on the side of the first housing 1 facing the bottom housing 4, and the micro switch 311 is disposed on the circuit board 3. The circuit board 3 is mounted on the first housing 1, bringing the micro switch 311 closer to the first housing 1, thereby shortening the distance between the micro switch 311 and the trigger part 142. This ensures that the micro switch 311 can be successfully triggered even without a protruding structure on the lower surface of the trigger part 142, protecting the micro switch 311 from damage.

[0140] Furthermore, such as Figure 8 and Figure 7 As shown, there are three trigger parts 142. The elastic arms 141 are arranged in a one-to-one correspondence with each trigger part 142. The trigger parts 142 on both sides are bent outwards. All three elastic arms 141 and three trigger parts 142 are located within the area of ​​the receiving groove 41 projected onto the first housing 1 to avoid interference between the elastic arms 141 and the first through hole 161. Each elastic arm 141 is a straight arm extending in the fourth direction. Because the first housing 1 has the first through hole 161, the positions of the left and right elastic arms 141 are offset towards the center. To ensure that the positions of the left and right trigger parts 142 correspond to the micro switch 311, the left trigger part 142 bends to the left, and the right trigger part 142 bends to the right. The trigger part 142 in the middle extends in the same direction as the elastic arm 141, and the ends of all trigger parts 142 are semi-circular. The trigger portions 142 on the left and right sides each cover 39% of the area of ​​the upper surface of the corresponding protective shell 3111, while the trigger portion 142 in the middle covers 40% of the area of ​​the upper surface of the corresponding protective shell 3111.

[0141] Existing smart switches are typically installed using screws. However, the screw-tightening process can cause deformation of the base shell, which can be transmitted to the circuit board and electronic switch, causing them to shift and affecting the normal triggering of the electronic switch. To avoid this problem, current technology usually fixes the circuit board carrying low-voltage signals to the middle shell. Since the middle shell is not affected by the deformation of the base shell, the impact of the base shell deformation on the circuit board is avoided. This solution generally uses two methods to fix the circuit board: the first is to directly fix the circuit board to the middle shell with screws; the second is to fix a protective plate on the lower side of the middle shell, clamping the circuit board between the protective plate and the middle shell. Although these two methods can isolate the effects of base shell deformation to a certain extent, their installation and disassembly processes are relatively cumbersome, making it difficult to improve assembly efficiency.

[0142] To address the aforementioned issues, this invention proposes a novel smart switch 100 with a novel fixing structure. This structure employs a first housing 1 with a positioning part 18 for positioning the circuit board 3, which improves ease of assembly and disassembly while ensuring stability.

[0143] Specifically, such as Figure 9 and Figure 10 As shown, the circuit board 3 has a first circuit surface facing the button 2 and a second circuit surface away from the button 2. An electronic switch 31 is provided on the first circuit surface, and the button 2 can directly or indirectly trigger the electronic switch 31 under pressure.

[0144] According to embodiments of this disclosure, the button 2 can directly trigger the electronic switch 31, for example, by passing directly through a 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 using other structures to assist in triggering the electronic switch 31. Regarding indirect triggering, one embodiment of the disclosure provides a possible implementation method: a triggering part 142 is provided between the button 2 and the electronic switch 31, and the button 2 presses against the triggering part 142 to trigger the electronic switch 31.

[0145] Furthermore, in one possible implementation, the first circuit surface of the circuit board 3 can be understood as... Figure 19 The upper surface of circuit board 3, the second circuit surface, can be understood as... Figure 19 The lower surface of circuit board 3. Based on this, the thickness direction of circuit board 3 can be understood as... Figure 19 The direction that is vertically downwards.

[0146] The first housing 1 abuts against the surface of the first circuit, such as Figures 15-19 As shown, where, Figure 15 and Figure 16 For the perspective after flipping up and down, the first housing 1 is provided with a plurality of positioning parts 18 facing the circuit board 3. Each positioning part 18 includes a positioning unit. The positioning unit protrudes from the second circuit surface and abuts against the circuit board 3. Thus, when the pressing pressure of 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.

[0147] Furthermore, during the installation of circuit board 3, the first circuit surface abuts against the first housing 1, and the second circuit surface is supported by the positioning unit, thereby achieving stable positioning of circuit board 3 between the first housing 1 and the positioning unit. During operation, when button 2 is pressed, the pressing force is transmitted to circuit board 3 through electronic switch 31. The displacement of circuit board 3 in the thickness direction is locked by the upward positioning force provided by the positioning unit, ensuring reliable triggering of electronic switch 31.

[0148] Through this structural design, the displacement of the circuit board 3 is firmly locked by the positioning part 18, and reliable support and positioning of the circuit board 3 can be achieved without the need for screws, which greatly improves the ease of disassembly and assembly of the circuit board 3.

[0149] It is worth mentioning that, in this embodiment of the present disclosure, the design of the positioning unit protruding from the circuit board 3 ensures the stability and sufficient support of the positioning of the circuit board 3, thereby avoiding unnecessary displacement of the circuit board 3 under pressure and ensuring that the switch can be successfully triggered.

[0150] In some embodiments, such as Figure 18 and Figure 19 As shown, the circuit board 3 carries both high-voltage and low-voltage circuits, and the bottom shell 4 is provided with a receiving groove 41, in which both the circuit board 3 and the positioning part 18 are accommodated. Therefore, in this embodiment, the circuit board 3 simultaneously carries both high-voltage and low-voltage circuits, eliminating the need for a separate high-voltage circuit board 3 and a partition, thus avoiding interference between the positioning unit and the partition. Furthermore, by placing both the circuit board 3 and the positioning part 18 in the receiving groove 41, interference between the positioning unit and the bottom shell 4 is avoided, and the circuit board 3 and the positioning part 18 also avoid occupying the thickness of the first shell 1, allowing for a reduction in the panel thickness of the smart switch 100.

[0151] Furthermore, such as Figure 15 and Figure 16As shown, the circuit board 3 has a first connecting end and a second connecting end away from the first connecting end. The plurality of positioning parts 18 include at least one first positioning part 182 and at least two second positioning parts 183. The first positioning part 182 is disposed at a position corresponding to the first connecting end, and the second positioning part 183 is disposed near the second connecting end. The first positioning part 182 includes a first connecting arm 1821 extending from the first housing 1 and a first positioning unit 1822 disposed at the end of the first connecting arm 1821. The second positioning part 183 includes a second connecting arm 1831 extending from the first housing 1 and a second positioning unit 1832 disposed at the end of the second connecting arm 1831. The first positioning unit 1822 and the second positioning unit 1832 respectively abut against the second circuit surface of the circuit board 3 to lock the displacement of the circuit board 3 in the thickness direction. Wherein, as... Figure 16 As shown, the rigidity of the first connecting arm 1821 is greater than that of the second connecting arm 1831. Because the first connecting arm 1821 has higher rigidity, it is not easy to deform, while the second connecting arm 1831 has lower rigidity and is easy to deform. Therefore, when installing the circuit board 3, the first connecting end is first inserted between the first positioning unit 1822 and the first housing 1, and then the second connecting end is pressed towards the first housing 1. The second positioning unit 1832 is squeezed by the circuit board 3, which causes the second connecting arm 1831 to undergo elastic deformation. Then the circuit board 3 is inserted between the second positioning unit 1832 and the first housing 1 to complete the installation of the circuit board 3. The whole installation process is simple and quick, which helps to improve assembly efficiency.

[0152] In this embodiment, both the first positioning unit 1822 and the second positioning unit 1832 are positioning units. The second positioning part 183 being located near the second connecting end can be understood as either being located at the end corresponding to the second connecting end, or being located on both sides of the circuit board 3 near the second connecting end. In one embodiment, the second positioning part 183 is located on both sides of the circuit board 3. This embodiment employs at least one first positioning part 182 with higher rigidity and at least two second positioning parts 183 with lower rigidity in cooperation. This not only improves the assembly efficiency of the circuit board 3 but also provides a stable positioning force. Furthermore, when disassembling the circuit board 3, the lower rigidity of the second positioning parts 183 facilitates prying; the circuit board 3 can be disassembled by prying open the two second positioning parts 183 one by one. The disassembly process is relatively simple and quick, facilitating the repair and replacement of the circuit board 3.

[0153] Because the second connecting arm 1831 has low rigidity, there is a risk that the circuit board 3 may detach when button 2 is pressed. Therefore, as follows: Figure 9As shown, the bottom shell 4 is provided with a receiving groove 41, and the circuit board 3 is received in the receiving groove 41. The second connecting arm 1831 is abutted by the side wall of the receiving groove 41 to enhance the deformation resistance of the second connecting arm 1831, so as to prevent the circuit board 3 from disengaging from the second positioning part 183 when the button 2 is pressed. When the first housing 1 is removed from the bottom shell 4, the second connecting arm 1831 is no longer abutted by the bottom shell 4, restoring its low rigidity characteristic, which facilitates the installation and removal of the circuit board 3. In this embodiment, by enhancing the deformation resistance of the second connecting arm 1831 through the bottom shell 4, not only is the circuit board 3 prevented from disengaging during use, but the advantage of easy installation and removal of the circuit board 3 is also retained.

[0154] Furthermore, such as Figure 19 and Figure 18 As shown, a first guide slope 44 is provided along the upper edge of the receiving groove 41, and a second guide slope 1833 is provided at the bottom of the second connecting arm 1831. The second guide slope 1833 is located on the side of the second connecting arm 1831 facing away from the circuit board 3. The first guide slope 44 and the second guide slope 1833 cooperate to facilitate the insertion of the second positioning part 183 into the receiving groove 41. In an exemplary embodiment, as... Figure 18 As shown, the first guide ramp 44 surrounds the upper edge of the receiving groove 41. Figure 19 As shown, when the first housing 1 is installed on the bottom housing 4, the first boss 13 of the first housing 1 is embedded in the first guide slope 44.

[0155] In one embodiment, such as Figure 16 and Figure 15 As shown, the circuit board 3 includes a first side edge and a second side edge disposed between the first connecting end and the second connecting end, with the first side edge and the second side edge located on opposite sides of the circuit board 3. There are two second positioning parts 183, and the second positioning units 1832 of the two second positioning parts 183 respectively abut against the first side edge and the second side edge. The two second positioning parts 183 are located on opposite sides of the circuit board 3 and are arranged opposite each other, so that the two less rigid second positioning parts 183 are subjected to balanced forces, thereby accurately locking the circuit board 3 in the position between the two second positioning parts 183. This avoids the second positioning part 183 being squeezed when it is arranged opposite to the more rigid first positioning part 182.

[0156] Furthermore, such as Figure 16 and Figure 15As shown, there are two first positioning parts 182. The first positioning units 1822 of the two first positioning parts 182 respectively abut against the first connecting end of the circuit board 3. The two first positioning parts 182 and the two second positioning parts 183 abut 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 connecting end of the circuit board 3 is abutted by the two first positioning parts 182, which can constrain the circuit board 3 in the horizontal direction, 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.

[0157] In one embodiment, 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 provided on the side of the first connecting arm 1821 facing away from the circuit board 3, and a second reinforcing rib is provided on the side of the second connecting arm 1831 facing away from the circuit board 3, wherein the width of the first reinforcing rib is greater than the width of 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.

[0158] In some embodiments, such as Figure 10 As shown, the electronic switch 31 is located on the line connecting the two second positioning parts 183, so that the positioning force provided by the second positioning part 183 acts more directly on the electronic switch 31, making the electronic switch 31 more stable in positioning and preventing the electronic switch 31 from being displaced when pressed.

[0159] In some embodiments, such as Figures 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 post 19. The first positioning post 19 is inserted into the first positioning hole 38 to lock the displacement of the circuit board 3 parallel to the surface of the first circuit. The direction parallel to the surface of the first circuit board 3 can be understood as the horizontal direction. The first positioning post 19 can improve the positioning accuracy of the circuit board 3 in the horizontal direction. Together with the first positioning part 182 and the second positioning part 183, it achieves precise positioning of the circuit board 3 in both the horizontal and vertical directions, thereby ensuring that the electronic switch 31 is accurately triggered.

[0160] Furthermore, the first positioning hole 38 is disposed on the circuit board 3 near the second connection end to improve the positioning accuracy of the circuit board 3 near the electronic switch 31 and ensure the positional accuracy of the electronic switch 31. And, as... Figure 16As shown, since the first positioning part 182 has high rigidity, the position of the circuit board 3 in the horizontal direction is mainly determined by the positioning post and the two first positioning parts 182. Setting the positioning post on the opposite side of the first positioning part 182 can increase the distance between the positioning post and the first positioning part 182, thereby improving the positioning accuracy of the circuit board 3.

[0161] like Figures 1-20 This is a three-button smart switch model 100. Figure 21 and Figure 22 This is a dual-button smart switch model 100. Figure 23 and Figure 24 This is a single-button smart switch 100. The difference between the two-button smart switch 100, the single-button smart switch 100, and the three-button smart switch 100 is that the three-button smart switch 100 has three button units 20. Correspondingly, the number of micro switches 311, panel units 231, driving units 224, trigger units 142, elastic arms 141, light-emitting elements 35, light-transmitting structures 11, light-transmitting holes 221, light-transmitting areas 21, and relays 32 are all three, and the number of wiring terminals 36 is five. The number of button units 20 in the two-button smart switch 100 is... For the two types of smart switches 100, the number of micro switches 311, panel units 231, driving units 224, trigger units 142, elastic arms 141, light-emitting elements 35, light-transmitting structures 11, light-transmitting holes 221, light-transmitting areas 21, and relays 32 are all two, and the number of wiring terminals 36 is four. For the single-button smart switch 100, the number of button units 20 is one, and the number of micro switches 311, panel units 231, light-transmitting areas 21, and relays 32 are all one. The button panel 23 is a complete panel, and the number of wiring terminals 36 is three.

[0162] It is worth noting that the single-button smart switch 100 and the three-button smart switch 100 have the same button bracket 22 and first housing 1 structure, which saves on mold opening costs. Therefore, the single-button smart switch 100 has three driving parts 224, trigger parts 142, elastic arms 141, light-emitting elements 35, light-transmitting structures 11, and light-transmitting holes 221.

[0163] Furthermore, compared to the three-button smart switch 100, the two-button smart switch 100 exhibits slightly different layouts in its micro switch 311, light-emitting element 35, light-transmitting structure 11, light-transmitting hole 221, and light-transmitting area 21, which are adaptively adjusted according to the number of button units 20. The positions of the light-shielding part 223 and the partial recess 123 are also slightly adjusted according to the number of buttons 2. The positions of the relay 32 and the wireless communication module 33 are also slightly different. The circuitry of the two-button, single-button, and three-button smart switches 100 differs slightly. Aside from the above differences, the other structural features of the two-button, single-button, and three-button smart switches 100 are identical.

[0164] It is worth noting that the elastic arm 141 and trigger part 142 of the two-button smart switch 100, the single-button smart switch 100 and the three-button smart switch 100 have the same structure, and the number of elastic arms 141 and trigger parts 142 does not change with the number of button units 20.

[0165] In another embodiment of the invention, such as Figure 26 As shown, an integrated button 2 is provided in this embodiment. Figures 1-20 The difference in the illustrated embodiment is that the button bracket 22 and the button panel 23 are integrated, and the button 2 is made of plastic material through injection molding. Due to the low rigidity of plastic, the back of the button 2 is provided with reinforcing ribs to enhance the button 2's resistance to deformation. In addition, since the button 2 no longer uses a glass panel, there is no need to worry about the glass panel being damaged due to excessive deformation of the button 2. Therefore, the button 2 no longer has the first dividing slit 271, and the connecting part 24 extends directly to the third end. Furthermore, since the button 2 no longer uses a glass panel, it is impossible to laser engrave complex text or patterns. In this embodiment, the button 2 only has a small hole to form the light-transmitting area 21.

[0166] It is important to note that Figure 26 The embodiments shown are compared to Figures 1-20 The embodiment shown is identical in all aspects except for button 2; therefore, Figure 26 Other structures of this embodiment are omitted, and will not be described in detail here.

[0167] It should also be noted that the above embodiments can be combined with each other. For the same or similar concepts or processes, they may not be described again in some embodiments. That is, the technical solutions disclosed in the later (in the order of the text) embodiments should include the technical solutions described in this embodiment and the technical solutions described in all embodiments before this embodiment.

[0168] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
