[0046] The intelligent switch is generally designed with a light-transmitting pattern on the surface of the key, and the pattern produces a light-emitting effect through the irradiation of the LED lamp inside the switch. In order to make the brightness of the pattern display more uniform, a light uniforming sheet is generally arranged between the LED lamp and the key, the light uniforming sheet corresponds to the pattern, and the light emitted by the LED lamp is irradiated to the pattern after being uniformed by the light uniforming sheet. However, the positioning and pasting of the light uniforming sheet are relatively troublesome, which brings inconvenience to the assembly of the intelligent switch.

[0047] In order to solve the above problems, according to the first aspect of the present utility model, as shown in Figures 1-11 A thin-wall light uniforming panel structure is provided. Please refer to Figure 4The thin-wall light-uniform panel structure comprises a first shell 1, a button 2 and a light-emitting piece 31; the button 2 is arranged on a first side of the first shell 1; the light-emitting piece 31 is arranged on a second side of the first shell 1, which is opposite to the first side; wherein the first shell 1 is provided with a thin-wall light-uniform area 11 at a position corresponding to the light-emitting piece 31, the light-emitting piece 31 transmits light through the thin-wall light-uniform area 11, and the light transmitted by the thin-wall light-uniform area 11 is provided as a light signal to the outside through a light-transmitting area 222 of the button 2. The light-transmitting area 222 can be understood as a character or a pattern capable of transmitting light, the light transmitted by the thin-wall light-uniform area 11 is transmitted through the light-transmitting area 222, so that the surface of the button 2 displays the light-emitting character or pattern, and the light-emitting character or pattern forms the light signal, which is used for indicating button information or a working state to the outside. The first shell 1 can be understood as a panel shell. The light-emitting piece 31 can be an LED lamp or other electronic elements capable of emitting light, and in an exemplary embodiment, the light-emitting piece 31 is an LED lamp. The thin-wall light-uniform area 11 is configured as an area with a very thin wall thickness and a light-transmitting function, and the light produces a light-uniform effect when transmitting through the thin-wall light-uniform area 11.

[0048] In the utility model, the thin-wall light-uniform area 11 has the functions of light transmission and light uniformity, and the thin-wall light-uniform area 11 is formed by locally thinning the first shell 1, that is, the thin-wall light-uniform area 11 is formed when the first shell 1 is injection molded, so that it is not necessary to additionally install a light-uniform sheet, the assembly steps are simplified, the assembly efficiency is improved, the number of materials is reduced, and the manufacturing cost is lowered.

[0049] The thin-wall light-uniform panel structure provided by the utility model is not only suitable for the intelligent switch 100, but also suitable for other electronic products with buttons and panels, and the intelligent switch 100 is taken as an example for detailed description in the following, but the protection scope of the utility model is not limited to the intelligent switch 100.

[0050] Further, as shown in the drawings, Figure 4 The second side of the first shell 1 is provided with a light-emitting groove 12, the light-emitting groove 12 thins the wall thickness of the first shell 1, so that the first shell 1 forms the thin-wall light-uniform area 11 between the light-emitting groove 12 and the first side; the button 2 is provided with the light-transmitting area 222 at a position opposite to the thin-wall light-uniform area 11, and the light-emitting piece 31 is arranged at a position corresponding to the light-emitting groove 12, the light emitted by the light-emitting piece 31 transmits through the thin-wall light-uniform area 11 and is transmitted to the outside by the light-transmitting area 222 after light-uniformization by the thin-wall light-uniform area 11. The light-emitting piece 31 arranged at a position corresponding to the light-emitting groove 12 can be understood as that the light-emitting piece 31 is arranged in the light-emitting groove 12 or arranged at a position opposite to the light-emitting groove 12, so that the light emitted by the light-emitting piece 31 can irradiate into the light-emitting groove 12.Figure 4 In some embodiments, the light-emitting groove 12 is configured as a downwardly open groove structure, and a top wall of the light-emitting groove 12 forms the thin-wall light-diffusing area 11.

[0051] To explore the optimal wall thickness of the thin-wall light-diffusing area 11, the researchers tested the light-diffusing effect of the thin-wall light-diffusing area 11 with different wall thicknesses in multiple tests. It was found through the tests that when the wall thickness is greater than 0.6 mm, the light-transmitting ability of the thin-wall light-diffusing area 11 is significantly weakened, and the light transmittance is less than 30%. When the wall thickness is less than 0.2 mm, the injection molding success rate of the first shell 1 decreases, and the thin-wall light-diffusing area 11 is damaged with a high probability, and the yield is significantly reduced. Therefore, according to the above test structure, in the preferred embodiments, the wall thickness of the thin-wall light-diffusing area 11 is less than 0.6 mm and greater than 0.2 mm, so as to ensure that the thin-wall light-diffusing area 11 has sufficient light transmittance while improving the injection molding success rate. In a specific embodiment, the wall thickness of the thin-wall light-diffusing area 11 is 0.4 mm.

[0052] In some embodiments, as shown in Figure 1 and Figure 2 The key 2 includes a glass panel 22, and a light-shielding layer covers one side of the glass panel 22 facing the first shell 1, and the light-shielding layer is hollowed out to form the light-transmitting area 222. The light-shielding layer includes a color layer facing the glass panel 22 and a black paint layer facing the first shell 1, the color layer is used to make the glass panel 22 present color, and the black paint layer is used for light shielding. The light-shielding layer is engraved with a hollow pattern by laser engraving, and the hollow pattern forms the light-transmitting area 222, and light passes through the light-transmitting area 222 to form a light-emitting pattern on the glass panel 22. Further, the glass panel 22 adopts AG frosted glass, which has a slight light-diffusing effect, and cooperates with the thin-wall light-diffusing area 11 to achieve better light-diffusing effect.

[0053] In other embodiments, the light-transmitting area 222 can also be a through hole formed on the key 2. Compared with the through hole, the key 2 adopts the glass panel 22 to engrave the hollow pattern, which not only facilitates the processing of complex and diverse patterns, but also avoids the key 2 opening, and retains the integrity of the key 2.

[0054] Further, as shown in Figure 2 and Figure 5As shown, the key 2 further comprises a plastic support 21, the glass panel 22 is fixedly connected to the plastic support 21, and the plastic support 21 is rotationally connected to the first shell 1. The structure of the plastic support 21 cooperating with the glass panel 22 in this embodiment enables the key 2 to have the ability of easy processing and shaping of plastic material and the rigidity of glass, so that the key 2 meets the connection function while having strong anti-deformation ability, and enables the key 2 to avoid being unable to trigger the electronic switch 32 due to too large deformation when being pressed while being thinned. The fixed connection between the glass panel 22 and the plastic support 21 can be adhesion, riveting, clamping or other fixed connection modes, and preferably, the glass panel 22 is adhered to the plastic support 21.

[0055] Further, as shown in Figure 2 and Figure 5 , the first shell 1 is provided with a first rotating shaft 13, and the plastic support 21 is provided with a first clamping jaw 213 adapted to the first rotating shaft 13, and the first clamping jaw 213 is clamped to the first rotating shaft 13 to realize the rotational connection of the key 2 and the first shell 1.

[0056] Further, the plastic support 21 is provided with a light transmission hole 212 at a position corresponding to the light transmission area 222, and the light transmission area 222 is located within the range of the light transmission hole 212. The light transmitted by the thin-walled light uniformization area 11 passes through the light transmission hole 212 and irradiates to the light shielding layer, and then is transmitted by the light transmission area 222.

[0057] In some embodiments, as shown in Figure 4 , the thin-walled light uniformization panel structure further comprises a circuit board 3 arranged on the second side of the first shell 1, and the light emitting member 31 is arranged in the light emitting groove 12. Wherein, arranging the light emitting member 31 in the light emitting groove 12 enables the light emitted by the light emitting member 31 to be reflected in the light emitting groove 12, thereby enhancing the light transmission intensity of the thin-walled light uniformization area 11.

[0058] Further, as shown in Figure 4 , the circuit board 3 is fixedly connected to the first shell 1, and the circuit board 3 covers the bottom of the light emitting groove 12. Wherein, covering the circuit board 3 at the bottom of the light emitting groove 12 and arranging the light emitting member 31 in the light emitting groove 12 can prevent the light emitted by the light emitting member 31 from irradiating to other areas to cause light leakage.

[0059] It is worth mentioning that the existing intelligent switch is usually fixed in the wall box by screws, however, the screwing process will cause the deformation of the bottom shell, and the deformation of the bottom shell will be transmitted to the circuit board and the electronic switch, causing the displacement of them, thereby affecting the normal triggering of the electronic switch. The circuit board 3 is fixedly connected to the first shell 1, and since the first shell 1 is not affected by the deformation of the bottom shell 4, the circuit board 3 is prevented from being affected by the deformation of the bottom shell 4, thereby ensuring the normal triggering of the electronic switch 32.

[0060] Further, the surface of the circuit board 3 is configured as white at the position opposite to the light emitting groove 12, so as to avoid the color deviation caused by the reflection of the circuit board 3, and to enhance the reflection performance of the circuit board 3 at the position of the light emitting groove 12, thereby reducing the brightness loss of the light in the reflection process. In an exemplary embodiment, the surface of the circuit board 3 is silk-screened with white oil at the position corresponding to the light emitting groove 12. In other embodiments, the color can also be changed by pasting a white film. Further, the first shell 1 is formed by white plastic injection molding, and the inner walls of the light emitting grooves 12 are white, so as to reduce the brightness loss of the light in the reflection process.

[0061] Further, as shown in Figure 10 each light emitting groove 12 is provided with a plurality of light emitting pieces 31, which not only can improve the brightness of the thin-wall uniform light area 11, but also make the light emitted by the thin-wall uniform light area 11 more uniform, thereby being beneficial to expanding the area of the thin-wall uniform light area 11 and enabling the light transmission area 222 to display more text or patterns. In a specific embodiment, four light emitting pieces 31 are arranged in each light emitting groove 12.

[0062] Further, as shown in Figure 11 and Figure 4 the circuit board 3 is provided with an electronic switch 32, and the button 2 can be pressed to trigger the electronic switch 32. The button 2 can directly drive the electronic switch 32, or indirectly drive the electronic switch 32 through other structures. The electronic switch 32 can be a micro switch, a tactile switch, a membrane switch or other types of electronic switch 32. In an embodiment, the electronic switch 32 is a micro switch. The button 2 is provided with a driving protrusion 214 at the position corresponding to the electronic switch 32, and a trigger portion 142 is arranged between the driving protrusion 214 and the electronic switch 32. The driving protrusion 214 presses the trigger portion 142 to trigger the electronic switch 32 through the trigger portion 142.

[0063] Further, as shown in Figure 4As shown, the trigger part 142 has a first surface arranged towards the micro switch, the first surface is used to trigger the micro switch, the first surface is not provided with a protruding structure, the first surface presses the micro switch through the whole surface, when the key 2 drives the micro switch to the trigger position through the trigger part 142, the first surface abuts against the protective shell of the micro switch, the protective shell supports the trigger part 142, thereby limiting the trigger part 142 and the key 2 to continue pressing. Because the area of the first surface is large, and the first surface is not provided with a protruding structure, when the first surface abuts against the protective shell, the contact area between the first surface and the protective shell is large, and the abutting pressure is small, thereby avoiding the protective shell being damaged by the trigger part 142; and the trigger part 142 is supported by the protective shell, thereby avoiding the driving rod of the micro switch being pressed beyond the limit stroke, and protecting the internal structure of the micro switch from being damaged.

[0064] As shown in the figure, Figure 6 The first shell 1 is provided with a reset part 14, the reset part 14 is used to provide a reset force for the key 2, the reset part 14 includes an elastic arm 141 extended out of the first shell 1 and the trigger part 142 arranged at the free end of the elastic arm 141, the trigger part 142 is located between the driving protrusion 214 and the electronic switch 32, the driving protrusion 214 indirectly triggers the electronic switch 32 by driving the trigger part 142; the elastic force of the elastic arm 141 is transmitted to the driving protrusion 214 through the trigger part 142 to provide the reset force. Wherein, the trigger part 142 and the elastic arm 141 are integrally formed on the first shell 1.

[0065] Further, as shown in the figure, Figure 2 The trigger part 142 is provided with a supporting protrusion 143 towards the key 2, the supporting protrusion 143 keeps abutting with the driving protrusion 214 of the key 2, so that when the key 2 is not pressed, the elastic arm 141 is in a pre-compressed state, the trigger part 142 provides a pre-tightening force, so that the key 2 will not be loose. And by adjusting the height of the supporting protrusion 143, the pre-tightening force and the reset force provided by the trigger part 142 can be adjusted, so that the pressing feeling of the key 2 is improved.

[0066] During the pressing process of the key 2, the relative movement between the key 2 and the supporting protrusion 143 in the horizontal direction will occur, and then the friction will be generated, which will cause the pressing feeling to be stuck. In order to solve this problem, as shown in the figure, Figure 2 The driving protrusion 214 is arranged at the corresponding position of the supporting protrusion 143, the key 2 abuts against the supporting protrusion 143 through the driving protrusion 214; the driving protrusion 214 and the supporting protrusion 143 are both configured as strip-shaped protrusions, and the two are arranged in a longitudinal and transverse staggered manner, so that the relative movement between the driving protrusion 214 and the supporting protrusion 143 will not interfere, thereby avoiding the pressing feeling to be stuck.

[0067] Further, as shown in Figure 1 and Figure 2 , the key 2 comprises at least one key unit 20, the plastic support 21 comprises a support unit 211, the glass panel 22 comprises a panel unit 221, and the support unit 211 and the panel unit 221 combine to form the key unit 20. When the smart switch 100 is a three-key smart switch 100, the number of the key unit 20 is three, when the smart switch 100 is a two-key smart switch 100, the number of the key unit 20 is two, and when the smart switch 100 is a single-key smart switch 100, the number of the key unit 20 is one. The utility model takes the three-key smart switch 100 as an example to make a detailed description.

[0068] The number and position of the light emitting piece 31, the light emitting groove 12, the light transmission region 222, the reset piece 14, and the electronic switch 32 correspond to the key unit 20. Each key unit 20 can trigger the corresponding electronic switch 32 when pressed, and the key unit 20 presses the corresponding reset piece 14, and each reset piece 14 provides a reset force for the key unit 20. As shown in Figure 1 and Figure 2 , when the smart switch 100 is a three-key smart switch 100, the number of the support unit 211 is three, and the number of the panel unit 221 is three, and the support unit 211 and the panel unit 221 combine to form the key unit 20. The panel unit 221 is configured as a glass sheet, and each panel unit 221 is attached to the support unit 211.

[0069] According to the second aspect of the utility model, as shown in Figures 1-11 , a smart switch 100 is provided, comprising the thin-walled light uniformization panel structure described above, further comprising: a bottom shell 4, the first shell 1 cover is arranged on the bottom shell 4; a circuit board 3, the light emitting piece 31 is arranged on the circuit board 3; the bottom shell 4 is provided with a containing recess 41, and the circuit board 3 is contained in the containing recess 41. Among them, the circuit board 3 is contained in the containing recess, can avoid the circuit board 3 to occupy the space of the first shell 1, makes the first shell 1 thinner, further reduces the thickness of the smart switch 100 located on the outside of the wall, to reach the visual effect of ultra-thin switch. At the same time, the circuit board 3 is contained in the containing recess, makes the depth of the light emitting groove 12 can be deeper, so that the light emitting piece 31 has sufficient light uniformization space, improves the light uniformization effect.

[0070] Further, as shown in Figure 10 , the number of the light emitting groove 12 is three, and at least part of each light emitting groove 12 is contained in the containing recess 41, so that the light emitting groove 12 sinks into the inside of the bottom shell 4, thereby reducing the thickness of the smart switch 100 located on the outside of the wall, achieving the visual effect of ultra-thin switch.

[0071] Further, the first rotating shaft 13 and the first clamping jaw 213 are arranged in the area projected by the accommodating groove 41 on the first shell 1, so that when the first clamping jaw 213 is clamped on the first rotating shaft 13, the first clamping jaw 213 can use the space of the accommodating groove 41, thereby the structure of the first shell 1 related to the first rotating shaft 13 can be sunk into the accommodating groove 41, which is beneficial to reduce the thickness of the smart switch 100 outside the wall surface.

[0072] Further, as shown in Figure 10 and Figure 7 , among the three light emitting grooves 12, the light emitting grooves 12 on both sides are respectively provided with open sides 121, the side walls of the accommodating groove 41 shield the open sides 121, the light emitting grooves 12, the circuit board 3 and the side walls of the accommodating groove 41 form a light emitting space, and the light emitting piece 31 is arranged in the light emitting space. That is, when the number of light emitting grooves 12 is three, because the light emitting grooves 12 are accommodated in the accommodating groove 41, the positions of the light emitting grooves 12 on both sides are limited by the accommodating groove 41, in order to make the positions of the light emitting grooves 12 on both sides close to the middle position of the key unit 20, the light emitting grooves 12 on both sides need to be as close to the side walls of the accommodating groove 41 as possible, and in this embodiment, the light emitting grooves 12 on both sides are opened towards the side walls of the accommodating groove 41 on both sides, the light emitting grooves 12 and the side walls of the accommodating groove 41 together enclose the light emitting space, so that the position of the accommodating groove 41 can be closer to the middle position of the key unit 20 on both sides, and further, the thin wall light uniform area 11 on both sides can be closer to the middle position of the key unit 20 on both sides.

[0073] Further, as shown in Figure 11 , the upper surface of the circuit board 3 is provided with a wireless communication module 33, the wireless communication module 33 is close to the edge position of the circuit board 3 and is located between the two electronic switches 32. Because the electronic switch 32 and the wireless communication module 33 are both close to the light emitting piece 31, in order to increase the area of the thin wall light uniform area 11 while avoiding the interference between the light emitting groove 12 and the electronic switch 32 and the wireless communication module 33, as shown in Figure 10 , Figure 7 and Figure 4 , the side wall of the light emitting groove 12 is provided with a avoiding gap 122 at the corresponding position of the light emitting piece 31 and the wireless communication module 33, the avoiding gap 122 is used to accommodate part of the light emitting piece 31 and the wireless communication module 33, so as to avoid the interference between the side wall of the light emitting groove 12 and the light emitting piece 31 and the wireless communication module 33.

[0074] Further, as shown in Figure 9 and Figure 8As shown, the circuit board 3 carries both strong current circuit and weak current circuit, the side of the circuit board 3 facing the bottom shell 4 is provided with relays 34 and wiring terminals 35, the number of the relays 34 is consistent with the number of the electronic switches 32, the relays 34 switch on-off state in response to the electronic switches 32 being triggered, the wiring terminals 35 are connected with zero line, fire line and control line for controlling the controlled device, the relays 34 are electrically connected with the wiring terminals 35, the relays 34 switch on-off state to control the controlled device to turn on or off. In addition, the circuit board 3 is provided with a power module, the power module is electrically connected with the wiring terminals 35, for converting household alternating current into low-voltage direct current, and then providing power for the weak current circuit.

[0075] Further, as shown in Figure 5 and Figure 2 each of the key units 20 is connected by the connecting part 215, which has the following beneficial effects: the gap width between each of the key units 20 is consistent; the key 2 is convenient to assemble in the first shell 1, improving the assembly efficiency; the circuit board 3 of the intelligent switch 100 is accommodated in the bottom shell 4, and the circuit board 3 carries the strong current circuit, when the intelligent switch 100 is installed, if the first shell 1 is disassembled, there is a risk of electric shock, therefore the first shell 1 cannot be disassembled when the intelligent switch 100 is installed, only the key 2 needs to be disassembled to expose the mounting hole 42, so as to install the intelligent switch 100, and the key units 20 connected by the connecting part 215 can facilitate the key 2 to be disassembled as a whole, improving the installation efficiency of the intelligent switch 100. As shown in Figure 9 and Figure 10 the bottom shell 4 is provided with mounting holes 42 on both sides, the mounting holes 42 penetrate the bottom shell 4 from top to bottom, the first shell 1 is provided with operation holes 17 at positions corresponding to the mounting holes 42, when the key 2 is disassembled, the operation holes 17 expose the mounting holes 42, so as to facilitate the user to install the screws.

[0076] However, the key units 20 connected by the connecting part 215 will bring another problem to the disassembly of the key 2: the key 2 is generally connected to the first shell 1 by a plurality of first clamping claws 213, if each of the first clamping claws 213 is disassembled one by one, some of the first clamping claws 213 will be in the clamping state, and the other part of the clamping claws will be in the disengaged state, in this case, the connecting part 215 will be twisted and deformed, thereby damaging the connecting part 215.

[0077] To solve this problem, as shown in Figure 5 and Figure 2As shown, the number of the first clamping claws 213 is two, which are arranged on both sides of the plastic support 21; the plastic support 21 is provided with at least one first clamping hook 216 between the two first clamping claws 213, the first shell 1 is provided with a second clamping hook 15 matched with the first clamping hook 216, the first clamping hook 216 is clamped on the second clamping hook 15, and the first clamping hook 216 is located on the connecting line of the two first clamping claws 213; wherein the clamping force between the first clamping claw 213 and the first shaft 13 is greater than the clamping force between the first clamping hook 216 and the second clamping hook 15, thereby forming a strong and weak combination connection mode, the first clamping claw 213 provides the main limiting, and the first clamping hook 216 provides the auxiliary limiting, when the first clamping claw 213 is disengaged, the first clamping hook 216 close to the first clamping claw 213 will also be automatically disengaged, avoiding the connection part 215 from being twisted and deformed, and protecting the connection part 215 from being damaged. In addition, when both the first clamping claws 213 are disengaged, the first clamping hook 216 will be automatically disengaged, facilitating the disassembly of the key 2. It is worth mentioning that since there are only two first clamping claws 213 on both sides of the key 2, the distance between the two first clamping claws 213 is large, which increases the deformation distance and reduces the deformation amount per unit length, thereby reducing the twisting and deformation of the connection part 215 and avoiding damage to the connection part 215.

[0078] It is worth mentioning that the second clamping hook 15 provides downward constraint for the key 2, when the two sides of the key 2 are pressed, the second clamping hook 15 can prevent the middle part of the key 2 from arching upward, improve the constraint on the key unit 20, and avoid the electronic switch 32 from being unable to trigger. Further, the second clamping hook 15 protrudes from the first shell 1, so that the second clamping hook 15 can support the key 2, and when the middle part of the key 2 is pressed, the second clamping hook 15 can prevent the middle part of the key 2 from being pressed to be concave. In summary, the second clamping hook 15 can not only constrain the key 2 from arching upward, but also avoid the key 2 from being concave downward, and its function is similar to that of the first shaft 13, but the clamping force of the first clamping hook 216 is weaker than that of the first clamping claw 213, and the second clamping hook 15 cooperates with the first clamping hook 216 to form a constraint similar to a rotating pair, thereby enhancing the stability of the rotating connection between the key 2 and the first shell 1.

[0079] Further, as shown in Figure 7 and Figure 8 , wherein, Figure 7 and Figure 8For the view angle of the upper and lower turnover, the circuit board 3 has a first connecting end close to the first rotating shaft 13 and a second connecting end away from the first connecting end, and the first shell 1 is provided with two first buckles 161 clamped on the first connecting end of the circuit board 3 and two second buckles 162 clamped on the two sides of the circuit board 3 close to the second connecting end, and the middle shell abuts against the upper surface of the circuit board 3, and the two first buckles 161 and the two second buckles 162 are clamped on the lower surface of the circuit board 3, so as to fix the circuit board 3 to the first shell 1.

[0080] Further, as shown in Figure 11 and Figures 7-8 , the circuit board 3 is provided with a positioning hole 36, and the first shell 1 is provided with a positioning column 18, and the positioning column 18 is inserted into the positioning hole 36 to improve the positioning accuracy of the circuit board 3 in the horizontal direction, and since the first buckle 161 and the second buckle 162 can limit the vertical displacement of the circuit board 3, the accurate positioning of the circuit board 3 in the horizontal and vertical directions is realized, and the accurate triggering of the electronic switch 32 is ensured.

[0081] Further, as shown in Figure 2 , Figure 5 and Figure 6 , wherein, Figure 5 is the view angle of the upper and lower turnover of the plastic support 21, the support unit 211 is provided with a light shielding rib 217 on the left and right sides of the light transmission hole 212 and the side away from the first claw 213, and the first shell 1 is provided with a light shielding recess 19, and the light shielding rib 217 is embedded in the light shielding recess 19 to achieve the light shielding effect and avoid the light from the gap between the key units 20 and the tail end of the key unit 20. Further, the light shielding recess 19 is provided with a local recess 191 inside the light shielding rib 217 at the corresponding position, and the local recess 191 is used to accommodate the light shielding rib 217 when the key 2 is pressed, so as to avoid the interference between the light shielding rib 217 and the first shell 1 when the key 2 is pressed.
