Description

Technical Field

[0001] This utility model relates to the field of intelligent switch technology, and in particular to an intelligent switch. Background Technology

[0002] With the development of smart homes, smart switches are gradually replacing traditional wall switches. As the triggering device for smart homes, smart switches play a crucial role in the entire system.

[0003] Existing smart switches typically house the high-voltage board in the bottom shell and the low-voltage board in the middle shell. An isolation plate is installed inside the bottom shell, forming a cavity that encloses the high-voltage board, exposing only the sockets on the high-voltage board. The low-voltage board connects to these sockets via pin headers. During installation from the middle shell to the bottom shell, it's crucial to ensure the pin headers on the low-voltage board align with the sockets on the high-voltage board. However, because the bottom shell is fixed to the wall, the wall obstructs the user's view, making it difficult to see the pin headers and sockets. This results in misalignment, reducing installation efficiency. Furthermore, when the pin headers are misaligned, pressing the middle shell can easily bend or damage them. Utility Model Content

[0004] Another objective of this invention is to provide an intelligent switch in which a first circuit board and a second circuit board are installed on the middle shell before the middle shell is installed on the bottom shell. The first circuit board and the second circuit board are electrically connected, and the first circuit board, the second circuit board, and the middle shell are integrated as a whole and installed into the bottom shell. Compared with existing installation methods, this installation method provided by this invention has the following advantages:

[0005] 1. The first circuit board, the second circuit board, and the middle shell are all hand-operated during installation. The operator can flip the parts so that the line of sight is not obstructed, which makes it easy to align the pins with the sockets. This not only improves the installation efficiency but also prevents the pins from being bent.

[0006] 2. After the middle shell is installed into the bottom shell, the first and second circuit boards are sealed inside the bottom shell. Users do not need to disassemble the middle shell when installing the smart switch on the wall. They only need to remove the button to install it, which makes the installation more convenient and avoids users damaging the pin header.

[0007] 3. Compared to existing smart switches that place the circuit board on the bottom shell and indirectly connect it to the middle shell, this embodiment directly mounts the first and second circuit boards on the middle shell. This shortens the dimensional chain between the first and second circuit boards and the middle shell, ensuring higher relative positional accuracy among the three components. Consequently, the relative positions of the pin header and the socket are more accurate, the connection is more stable, and the relative positions of the reset component and the electronic switch are also more accurate, ensuring that the reset component accurately triggers the electronic switch.

[0008] 4. When the bottom shell is installed on the wall, if the screws are tightened too much, the bottom shell will deform into the wall. Existing smart switches place the second circuit board on the bottom shell. Deformation of the bottom shell will cause the second circuit board to deform along with the bottom shell or move into the wall, which will lead to damage to the second circuit board or unstable connection between the second circuit board and the first circuit board. In this embodiment of the utility model, the first circuit board and the second circuit board are directly installed on the middle shell. Deformation of the bottom shell will not affect the second circuit board, thus avoiding damage to the second circuit board or unstable connection between the second circuit board and the first circuit board.

[0009] 5. In the existing system, the second circuit board is sealed inside the bottom shell by an isolation plate. To remove the second circuit board, the middle shell and the isolation plate must first be disassembled. Since the second circuit board is embedded at the bottom of the bottom shell and is held in place by the bottom shell's clips, it needs to be pried out with tools, making disassembly difficult and causing the second circuit board to be troublesome to repair. In this embodiment of the utility model, the second circuit board can be removed from the bottom shell by simply removing the middle shell, making disassembly much more convenient. Moreover, the second circuit board can be repaired without being removed from the middle shell, greatly improving the convenience of repair.

[0010] Another objective of this invention is to provide an intelligent switch in which a first circuit board is first installed on a first mounting part, and then a second circuit board is installed on a second mounting part. The middle shell, the first circuit board, and the second circuit board are distributed sequentially along a third direction, making installation more convenient.

[0011] Another objective of this invention is to provide an intelligent switch in which, when the second circuit board is installed in the middle shell, the pin header is inserted into the nut header to complete the electrical connection between the first circuit board and the second circuit board, thereby improving assembly efficiency.

[0012] Another objective of this invention is to provide an intelligent switch, wherein the first interval H1 is used for electrical isolation between the first circuit board and the second circuit board.

[0013] Another objective of this utility model is to provide an intelligent switch in which the first circuit board, the second circuit board and the middle shell are connected by hooks. The advantage of this is that during installation, the first circuit board is pressed into the first hook first, and then the second circuit board is pressed into the second hook to complete the installation, which greatly improves the installation efficiency.

[0014] Another objective of this utility model is to provide an intelligent switch, wherein the first end and the second end are opposite to each other, so that the first hook can stably limit the first circuit board and facilitate the first circuit board to be inserted into or removed from the first hook.

[0015] Another objective of this invention is to provide an intelligent switch in which the third end and the fourth end are opposite each other, so that the second hook can stably limit the second circuit board and facilitate the second circuit board to be inserted into or removed from the second hook.

[0016] Another objective of this invention is to provide an intelligent switch in which the direction of the first end toward the second end is perpendicular to the direction of the third end toward the fourth end, thereby providing more space for the arrangement of the first and second hooks and facilitating a more reasonable design of the hook positions.

[0017] Another objective of this invention is to provide an intelligent switch in which the positioning post is located in the diagonal area of ​​the second circuit board, which can improve positioning accuracy and make the relative position of the middle shell and the second circuit board in the horizontal direction accurate.

[0018] Another objective of this invention is to provide an intelligent switch in which the second support rib and / or positioning post positions the first circuit board, thereby ensuring that the relative position of the middle shell and the first circuit board in the horizontal direction is accurate.

[0019] Another objective of this invention is to provide an intelligent switch in which guide posts protrude from the second circuit board in a third direction, thereby protecting the second circuit board from collisions when it is placed into the base housing. Furthermore, the four guide posts provide installation guidance, improving the efficiency of placing the second circuit board into the base housing. The four corner areas of the second circuit board can be understood as the areas near the four corners of the second circuit board.

[0020] Another objective of this invention is to provide an intelligent switch in which the corner of the second circuit board 4 is enclosed inside the first included angle, so that the guide post can protect the second circuit board while saving space.

[0021] Another objective of this invention is to provide an intelligent switch in which the direction of the first mounting side toward the second mounting side is perpendicular to the direction of the first snap-fit ​​side toward the second snap-fit ​​side; thereby reducing the impact of deformation of the first mounting side and the second mounting side on the middle shell. This is because both the first circuit board and the second circuit board are mounted on the middle shell, thus avoiding the direct impact of deformation of the bottom shell on the first circuit board and the second circuit board.

[0022] Another objective of this invention is to provide an intelligent switch in which the locking component is locked in the wiring slot. This not only prevents the locking component from detaching from the wiring slot, but also facilitates the insertion of the conductive sheet into the locking component. Thanks to the fact that the second circuit board is integrated with the middle shell and installed into the bottom shell, when the operator installs the middle shell into the bottom shell, the conductive sheet automatically inserts into the locking component along with the second circuit board, which can greatly improve the installation efficiency.

[0023] To achieve at least one of the above objectives, the utility model provides an intelligent switch, including a bottom shell; a middle shell, which covers the bottom shell and forms a first receiving cavity with the bottom shell; a first circuit board carrying a low-voltage circuit and being received in the first receiving cavity; and a second circuit board carrying a high-voltage circuit and being received in the first receiving cavity; the first circuit board and the second circuit board are respectively mounted on the middle shell, and then integrally mounted on the bottom shell with the middle shell.

[0031] In some embodiments, the first circuit board has a first surface facing the middle shell, and an electronic switch is provided on the first surface. A button is provided on the side of the middle shell opposite to the first circuit board, and the button can be pressed to directly or indirectly trigger the electronic switch. The bottom shell has a first mounting side and a second mounting side disposed opposite to each other, as well as a first snap-fit ​​side and a second snap-fit ​​side disposed opposite to each other. The first mounting side and the second mounting side are respectively provided with mounting holes, and the bottom shell is mounted to a wall-mounted junction box through the mounting holes. The first snap-fit ​​side and the second snap-fit ​​side are respectively snapped into the middle shell. The direction of the first mounting side toward the second mounting side is perpendicular to the direction of the first snap-fit ​​side toward the second snap-fit ​​side.

[0032] In some embodiments, the system further includes a plurality of terminals, each terminal including a conductive sheet soldered to the second circuit board and a locking assembly disposed on the bottom shell.

[0065] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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.

[0066] Existing multi-button smart switches are generally assembled from multiple independent button panels. This method results in button panels with uneven gaps and varying heights, and also has low assembly efficiency. In existing technology, a one-piece button panel has been designed, using a connecting part to link the buttons together. While this design solves the problems of uneven gaps, varying heights, and low assembly efficiency, it also introduces some new issues: when the button panel consists of a plastic support and a rigid button cover, the buttons' resistance to deformation is strengthened. However, due to the limited deformation of the connecting part, when one button is pressed, adjacent buttons will move, causing false triggering of other buttons.

[0067] This problem is particularly prominent in glass-type switches, which can be understood as switches using a glass cover. In current technology, a glass cover is typically glued to a plastic bracket, leveraging the high rigidity (resistance to deformation) of the glass cover to enhance the button's resistance to deformation. The connecting part integrates the plastic bracket. Due to the limited deformation capacity of the connecting part, when one button is pressed, other adjacent buttons will move accordingly, causing multiple electronic switches to be triggered in a coordinated manner. To solve the button linkage problem, the conventional approach is to shorten the dimensions of the connecting part, increasing its deformation capacity. However, this reduces the strength of the connecting part, making it easier to damage when disassembling the button panel.

[0068] Based on the above technical background, according to the first aspect of this utility model, a button structure 1 is provided. Please refer to [link / reference]. Figures 1-6 and Figures 18-21 The button structure 1 will be explained in detail.

[0069] exist Figures 1-6 In this embodiment, both ends of the button structure 1 can be pressed. Figures 18-21 In this embodiment, only one end of the button structure 1 can be pressed. The scope of protection of this utility model includes, but is not limited to, button structures 1 with these two pressing methods.

[0070] The button structure 1 includes a button bracket 11 and a button cover 12; the button bracket 11 includes at least two bracket units 111 and a connecting portion 112 connecting two adjacent bracket units 111; the button cover 12 is fixedly connected to the bracket units 111; wherein, the bracket units 111 are arranged side by side along a first direction, and there is a first gap 113 between adjacent bracket units 111, the extension direction of the first gap 113 is set as a second direction; the length of the connecting portion 112 in the first direction is greater than the width of the first gap 113, and the connecting portion 112 is not directly fixed to the button cover 12; the connecting portion 112 is connected to the bracket units 111 in the first direction, and the two are disconnected in the second direction.

[0071] Because the support unit 111 is fixedly connected to the key cover plate 12, the deformation resistance of the support unit 111 is enhanced by the key cover plate 12. When the key is pressed, the support unit 111 needs to rely on the connecting part 112 to generate twisting deformation to avoid key linkage. In existing integrated keys, the length of the connecting part in the first direction is equal to the width of the first gap, resulting in the connecting part being too short and having poor deformation ability. The width of the connecting part in the second direction must be shortened to ensure that the deformation ability meets the requirements, but this will reduce the strength of the connecting part, making it easy to damage the connecting part when disassembling the key panel.

[0072] In this embodiment of the present invention, the length of the connecting part 112 in the first direction is greater than the width of the first gap 113, and the connecting part 112 is disconnected from the support unit 111 in the second direction, so that the connecting part 112 has a sufficiently long deformation space in the first direction. Furthermore, since the connecting part 112 is not directly fixed to the button cover plate 12, the deformation of the connecting part 112 is not constrained by the button cover plate 12, thereby ensuring that the deformation of the connecting part 112 is large enough and avoiding linkage between the support units 111.

[0073] Furthermore, thanks to the sufficient length of the connecting part 112 in the first direction, the width of the connecting part 112 in the second direction can be designed to be wider while meeting the deformation requirements, thereby ensuring the strength of the connecting part 112 and preventing damage to the connecting part 112 during disassembly.

[0074] The button bracket 11 is used to realize the relevant functions of the buttons, such as connecting the middle shell 2, realizing button movement, triggering the electronic switch 31, etc. The button bracket 11 connects the button structure 1 into one unit, ensuring that the button covers 12 are flush, the width of the first gap 113 is consistent, and the assembly efficiency of the button structure 1 into the smart switch 100 is higher. The button bracket 11 can be made of plastic material for easy manufacturing. The button covers 12 are generally made of materials with high rigidity, such as glass or metal, to improve the deformation resistance of the bracket unit 111, improve the pressing feel, and improve wear resistance.

[0075] The connection between the bracket unit 111 and the button cover plate 12 can be achieved by bonding, riveting, or other fixed connection methods.

[0076] The fact that the connecting part 112 is not directly fixed to the key cover plate 12 can be understood as meaning that there is no direct physical connection or fixation between the connecting part 112 and the key cover plate 12 through screws, adhesives, or other connection methods. Of course, there may be indirect contact or indirect connection through other intermediary components. For example, in this embodiment, the connecting part 112 is indirectly connected to the key cover plate 12 through the bracket unit 111, and there is no direct fixed connection between the connecting part 112 and the key cover plate 12. The first and second directions have already... Figure 3 and Figure 20 The diagram indicates that the first direction can be left or right as shown in the image, and the second direction can be up or down as shown in the image.

[0077] In some embodiments, the disconnection of the connection portion 112 from the support unit 111 in the second direction can be a complete disconnection or a partial disconnection.

[0078] Furthermore, such as Figures 1-4 as well as Figures 18-21As shown, the number of button cover plates 12 matches the number of support units 111. Each button cover plate 12 is correspondingly glued and fixed to a support unit 111. The connecting portion 112 is not glued or fixed to the button cover plate 12. The support unit 111 and the button cover plate 12 are bonded together with double-sided adhesive 13, ensuring a close fit and a sufficiently large connection area. This allows the button cover plate 12 to more effectively enhance the deformation resistance of the support unit 111. The fact that the connecting portion 112 is not glued or fixed to the button cover plate 12 ensures that the deformation of the connecting portion 112 is not constrained by the button cover plate 12, thus guaranteeing a sufficiently large deformation range and preventing linkage between the support units 111. In an exemplary embodiment, double-sided adhesive tape 13 is attached to the upper surface of the support unit 111 and to the lower surface of the button cover 12 to achieve the bonding and fixing of the button cover 12 and the support unit 111. The double-sided adhesive tape 13 is cut out with blank area 131 at the corresponding position of the connecting part 112, so that the button cover 12 and the connecting part 112 are not bonded and fixed.

[0079] The double-sided adhesive 13 is cut to fit the shape of the button bracket 11, so that the double-sided adhesive 13 can cover more than 70% of the upper surface area of ​​the button bracket 11, thereby ensuring stable adhesion between the bracket unit 111 and the button cover plate 12. In one embodiment, the double-sided adhesive 13 covers 84% ​​of the upper surface area of ​​the button bracket 11.

[0080] In some embodiments, such as Figures 3-4 and Figures 20-21 As shown, there is a disconnection region 114 between the connecting part 112 and the support unit 111. The disconnection region 114 disconnects the connecting part 112 and the support unit 111 in the second direction. The disconnection region 114 connects to the first gap 113, making it difficult for the movement generated by the support unit 111 when it is pressed to be transmitted from the second direction to the connecting part 112. The movement of the support unit 111 can only be transmitted from the left and right ends of the connecting part 112, further preventing linkage between the support units 111. The disconnection region 114 can be understood as a hollow area, which can be a strip-shaped gap, a triangular hollow area, or a hollow area of ​​other shapes.

[0081] Furthermore, such as Figure 3 and Figure 4 As shown, the disconnected region 114 is constructed as a second gap 1141, and the connecting portion 112 has the second gap 1141 respectively on both sides in the second direction, with the second gap 1141 extending along the first direction. The two sides of the connecting portion 112 in the second direction can be understood as... Figure 3 The top and bottom sides of the image, with the first direction being the horizontal direction shown in the figure. Figure 4In the embodiment shown, the connecting portion 112 laterally blocks the first gap 113, the first gap 113 is directly opposite the middle position of the connecting portion 112, the first gap 113 extends across the connecting portion 112 in the second direction, and when the first gap 113 extends to the connecting portion 112, it communicates with the second gap 1141.

[0082] Furthermore, such as Figure 3 and Figure 20 As shown, in the first direction, the length of the second gap 1141 is equal to the length of the connecting part 112, so that the connecting part 112 is completely disconnected from the support unit 111 in the second direction, making the connecting part 112 longer in the first direction and stronger in terms of deformation capacity.

[0083] Furthermore, the two ends of the second gap 1141 are arc-shaped to enhance the connection strength between the connecting part 112 and the support unit 111 and to prevent damage to the connecting part 112.

[0084] In some embodiments, the connecting portion 112 may be located at the middle or edge of the support unit 111 in the second direction to accommodate changes in the number of buttons. This utility model is described using only four-button and two-button smart switches 100 as examples, but the scope of protection of this utility model is not limited to four-button and two-button smart switches 100. Specifically, the button structure 1 provided by this utility model can be adapted to smart switches 100 with various numbers of buttons. The button structure 1 can be designed as single-sided or double-sided pressing according to the button number requirements. Single-sided pressing can be understood as only one end of the button structure 1 being pressable, and double-sided pressing can be understood as both ends of the button structure 1 being pressable. In some embodiments, the single-sided pressing button structure 1 is suitable for two-button, three-button, and four-button smart switches 100, and the double-sided pressing button structure 1 is suitable for four-button, six-button, and eight-button smart switches 100.

[0085] In some embodiments, such as Figure 2 and Figure 3 As shown, each of the bracket units 111 is provided with two trigger posts 1111, which are used to trigger the electronic switch 31.

[0086] Furthermore, in the second direction, the connecting portion 112 is located in the middle of the support unit 111, and the two trigger posts 1111 are respectively located on both sides of the connecting portion 112. The connection portion 112 being located in the middle of the support unit 111 can be understood as the connection portion 112 being located at the center of the support unit 111 in the second direction, or slightly off-center. In an exemplary embodiment, with the connecting portion 112 located at the center of the support unit 111 in the second direction, both ends of the button cover 12 can be pressed, thereby causing the trigger posts 1111 on both sides to trigger the corresponding electronic switches 31.

[0087] In some embodiments, such as Figure 20 As shown, in the second direction, the connecting portion 112 is located at the end of the support unit 111, the disconnected area 114 is configured as a second gap 1141, the connecting portion 112 has the second gap 1141 on one side in the second direction, and the second gap 1141 extends along the first direction. This is shown from the perspective of the back of the button bracket 11 (…). Figure 20 From the perspective shown, the connecting part 112 is located at the upper end of the support unit 111, the second gap 1141 is located at the lower side of the connecting part 112, the first gap 113 is directly opposite the middle position of the connecting part 112, and the first gap 113 extends upward to the connecting part 112 and communicates with the second gap 1141. A trigger post 1111 is provided at the lower part of the support unit 111. The lower end of the button cover plate 12 can be pressed to drive the trigger post 1111 to trigger the electronic switch 31.

[0088] In some embodiments, such as Figure 2 and Figure 20 As shown, the trigger post 1111 extends from the back of the support unit 111, and the cross-section of the trigger post 1111 is similar to a cross shape.

[0089] In some embodiments, such as Figure 3 and Figure 20 As shown, the two ends of the connecting portion 112 in the first direction are respectively connected to the support unit 111 to connect the support units 111 into one unit. When a button cover 12 is pressed and rotates, the torsional motion of the support unit 111 is transmitted to the end of the connecting portion 112 in the first direction, causing the connecting portion 112 to undergo torsional deformation. Thanks to the relatively long length of the connecting portion 112 in the first direction, the connecting portion 112 can generate sufficient deformation to prevent other support units 111 from moving in tandem with the connecting portion 112. Furthermore, the two ends of the connecting portion 112 in the first direction are integrally formed and connected to the support unit 111.

[0090] Furthermore, a thinning groove 115 is provided at the connection point between the connecting portion 112 and the support unit 111. The thinning groove 115 is used to reduce the thickness at both ends of the connecting portion 112. The thinning groove 115 is constructed as a groove extending along a second direction. This enhances the deformability at both ends of the connecting portion 112, preventing linkage between the support units 111. The thinning groove 115 also prevents deformation of the connecting portion 112 from propagating to the support unit 111, thus preventing deformation of the support unit 111 near the thinning groove 115 and subsequent detachment from the button cover 12.

[0091] Furthermore, such as Figure 2 and Figure 20 As shown, the button bracket 11 is provided with first reinforcing ribs 116 at the left and right ends of the connecting portion 112, respectively. The first reinforcing ribs 116 are located on the outside of the thinning groove 115 and extend along the second direction. The first reinforcing ribs 116 are used to strengthen the rigidity of the bracket unit 111 at the two ends of the connecting portion 112, further preventing the deformation of the connecting portion 112 from propagating to the bracket unit 111, and preventing the bracket unit 111 from deforming at the location of the first reinforcing ribs 116, causing it to detach from the button cover plate 12.

[0092] In some embodiments, such as Figure 2 , Figure 5 and Figure 19 As shown, the connecting part 112 is constructed as a flat plate structure, which is fitted to the button cover plate 12 or has a gap of less than 0.5mm, so that the connecting part 112 will not increase the thickness of the button bracket 11, allowing the button structure 1 to be adapted to the ultra-thin switch panel.

[0093] In some embodiments, such as Figure 3 and Figure 20 As shown, the width of the connecting part 112 in the second direction is set to W1, and the width of the support unit 111 in the second direction is set to W2. In this embodiment of the utility model, W1 is controlled to be: 0.12×W2≤W1≤0.27×W2, so that the connecting part 112 can meet the deformation performance requirements while ensuring its strength.

[0094] exist Figure 3 In the specific embodiment shown, W1 = 11.7 mm, W2 = 59.7 mm, and W1 = 0.196 × W2; Figure 20 In the specific embodiment shown, W1 = 9.9 mm, W2 = 54.1 mm, and W1 = 0.183 × W2.

[0095] like Figure 3 and Figure 20As shown, the length of the connecting part 112 in the first direction is set as L1, and the length of the support unit 111 in the first direction is set as L2. In this embodiment of the utility model, L1 is controlled to be 0.3×L2≤L1≤0.75×L2, so that the connecting part 112 can meet the deformation performance requirements while ensuring the stable connection of the claw 1171.

[0096] Among them, Figure 3 In the specific embodiment shown, L1 = 24.4 mm, L2 = 38.5 mm, and L1 = 0.634 × L2; Figure 20 In the specific embodiment shown, L1 = 23.7 mm, L2 = 37.7 mm, and L1 = 0.629 × L2.

[0097] In some embodiments, the rigidity of the button cover 12 is greater than the rigidity of the button bracket 11. The rigidity can be understood as the ability to resist elastic deformation. The greater the rigidity, the smaller the elastic deformation under the same force, and the smaller the rigidity, the greater the elastic deformation under the same force.

[0098] In a specific example, the button bracket 11 is made of plastic. However, plastic has poor rigidity. When the end of the button bracket 11 is pressed, excessive deformation can prevent the electronic switch 31 from being triggered. A common approach to reduce deformation is to increase the thickness of the button bracket 11, but this results in an excessively thick button bracket 11. Therefore, in this embodiment of the invention, a button cover plate 12 is attached to the button bracket 11. The button cover plate 12 is made of a highly rigid material to improve the deformation resistance of the bracket unit 111, ensuring that the bracket unit 111 successfully triggers the electronic switch 31.

[0099] In one specific example, the button cover 12 is made of glass, allowing it to be as thin as possible while maintaining high rigidity, thus enabling the button structure 1 to fit an ultra-thin switch panel. In other examples, the button cover 12 may be made of metal or other materials with greater rigidity than plastic.

[0100] like Figures 1-22 As shown, in some embodiments, a smart switch 100 is also provided. Wherein, Figures 1-17 This is an embodiment of a four-button smart switch 100. Figures 18-22 This invention describes an embodiment of a two-button smart switch 100, using a four-button or two-button smart switch 100 as an example. However, the scope of protection of this invention is not limited to the four-button or two-button smart switch 100.

[0101] The smart switch 100 includes the aforementioned button structure 1, and also includes a middle shell 2, as shown below. Figure 8 and Figure 19As shown, the button bracket 11 is provided with a first snap-fit ​​portion 117, and the middle shell 2 is provided with a second snap-fit ​​portion 21. The first snap-fit ​​portion 117 snaps into the second snap-fit ​​portion 21, and the bracket unit 111 and the button cover plate 12 can rotate based on the second snap-fit ​​portion 21. The first snap-fit ​​portion 117 can be a snap-fit ​​shaft, a snap-fit ​​claw 1171, a snap-fit ​​hole, or other snap-fit ​​structure, and the second snap-fit ​​portion 21 is constructed as a snap-fit ​​hole, a snap-fit ​​shaft, or other snap-fit ​​structure that mates with the first snap-fit ​​portion 117.

[0102] like Figure 3 and Figure 20 As shown, there are multiple first latching portions 117, each distributed along a first straight line 1172. The first straight line 1172 crosses the connecting portion 112 to reduce the deformation of the connecting portion 112 and prevent the support unit 111 from interfering with each other. The first straight line 1172 crossing the connecting portion 112 can be understood as the projection line formed by the first straight line 1172 projected onto the button bracket 11 facing the ground passing through the connecting portion 112. The first straight line 1172 has already... Figure 3 and Figure 20 Awarded. In specific examples, such as... Figure 3 In the illustrated embodiment, the projection line passes through the middle of the connecting portion 112, bisecting the connecting portion 112. In another example, such as... Figure 20 In the embodiment shown, the projection line is slightly off-center from the middle position of the connection portion 112.

[0103] Furthermore, such as Figure 8 , Figure 9 and Figure 19 As shown, each of the bracket units 111 is provided with two first locking portions 117. The first locking portion 117 is constructed as a claw 1171, and the second locking portion 21 is constructed as a rotating shaft 211. The claw 1171 is engaged with the rotating shaft 211, and the claw 1171 can rotate based on the rotating shaft 211. The claw 1171 protrudes from the lower surface of the bracket unit 111, and its lower end is open. The claw 1171 is engaged with the rotating shaft 211 from top to bottom.

[0104] It is worth noting that, such as Figure 5 As shown, the height of the claws 1171 protruding from the support unit 111 is relatively low, and the height of the two claws 1171 located on both sides of the support unit 111 is lower than the height of the two claws 1171 located in the middle of the support unit 111, so as to avoid interference between the claws 1171 and the bottom shell 5 when they are engaged with the rotating shaft 211. Specifically, the height of the claws 1171 protruding from the support unit 111 is less than 4 mm and greater than 1 mm.

[0105] In one embodiment, the height of the claws 1171 located on both sides of the support unit 111 is equal to 2.5 mm, and the height of the claws 1171 located in the middle of the support unit 111 is equal to 3 mm.

[0106] Furthermore, the first circuit board 3 is provided with an electronic switch 31, and the support unit 111 is provided with a trigger post 1111 at the corresponding position of the electronic switch 31. The button cover 12 can be pressed to drive the support unit 111 to rotate based on the rotating shaft 211, thereby the support unit 111 drives the trigger post 1111 to directly or indirectly trigger the electronic switch 31. When the trigger post 1111 indirectly triggers the electronic switch 31, the trigger post 1111 can abut against other structures, and the electronic switch 31 is indirectly triggered by the pressure of other structures.

[0107] like Figure 8 , Figure 9 and Figure 19 As shown, the middle shell 2 is provided with a reset member 22 below each support unit 111 to provide button reset force.

[0108] Furthermore, the reset member 22 includes an elastic arm 221 extending from the middle shell 2.

[0109] Furthermore, the reset member 22 also includes a receiving boss 222 disposed at the free end of the elastic arm 221. The receiving boss 222 is located between the trigger post 1111 and the electronic switch 31. The trigger post 1111 indirectly triggers the electronic switch 31 by driving the receiving boss 222. The elastic force of the elastic arm 221 is transmitted to the support unit 111 through the receiving boss 222 to provide a reset force.

[0110] Furthermore, the receiving boss 222 and the elastic arm 221 are integrally formed in the middle shell 2.

[0111] Furthermore, the receiving boss 222 is a circular boss, and the driving rod of the electronic switch 31 is located below the receiving boss 222. The lower surface of the receiving boss 222 presses against the driving rod to trigger the electronic switch 31.

[0112] It is worth mentioning that, such as Figure 14As shown, since the diameter of the receiving boss 222 is larger than the diameter of the trigger post 1111, when the lower surface of the receiving boss 222 abuts against the housing of the electronic switch 31, the contact area between the receiving boss 222 and the housing of the electronic switch 31 is larger, resulting in lower pressure and preventing damage to the housing of the electronic switch 31. Furthermore, the receiving boss 222 is supported by the housing of the electronic switch 31, preventing the drive rod of the electronic switch 31 from being pressed beyond its limit stroke, thus protecting the internal structure of the electronic switch 31 from damage. In one embodiment, the electronic switch 31 is a micro switch.

[0113] Furthermore, such as Figure 14 As shown, when the button is not pressed, the elastic arm 221 is in a pre-compressed state, so that the receiving boss 222 and the trigger post 1111 remain in contact, and the receiving boss 222 provides a preload force. Furthermore, by adjusting the height of the trigger post 1111, the magnitude of the preload force and the reset force provided by the receiving boss 222 can be adjusted, so that the height of the trigger post 1111 can be designed to an optimal value, thereby improving the button's pressing feel.

[0114] In existing technologies, a limiting hook is typically provided at the end of the button. This limiting hook engages with the middle shell to limit the maximum upward movement of the button, ensuring that each button remains horizontal when not pressed. In this embodiment of the invention, thanks to the button bracket 11 being integrated through the connecting part 112, the connecting force generated by the connecting part 112 makes each bracket unit 111 flush. The bracket unit 111 does not need to be equipped with the aforementioned limiting hook, and the bracket unit 111 maintains a horizontal state by the pre-tightening force of the reset member 22.

[0115] Furthermore, such as Figure 10 As shown, mounting holes 51 are provided on both sides of the bottom shell 5. The mounting holes 51 are for inserting a first screw (not shown in the figure), and the bottom shell 5 is mounted to a wall-mounted junction box using the first screw. Figure 9 and Figure 19 As shown, the middle shell 2 has a first through hole 23 at the corresponding position of the two mounting holes 51. The first through hole 23 is used to accommodate the nut of the first screw, so that the nut does not occupy the thickness of the middle shell 2, which is beneficial to the thinning of the switch panel.

[0116] Existing smart switches typically require the removal of the middle shell before installation on the wall. This installation method has problems: after the smart switch is installed on the wall, if the installation position is found to be off-center or tilted, the middle shell needs to be pried off again and the screws loosened for fine-tuning. Using a screwdriver to pry open the middle shell can easily damage the wall surface. The smart switch 100 provided by this utility model eliminates the need to pry open the middle shell 2 during installation and disassembly, avoiding damage to the wall surface. Specifically, as follows... Figure 8As shown, after the button is disassembled, the first through hole 23 of the middle shell 2 and the mounting hole 51 of the bottom shell 5 are exposed. The first screw can be inserted into the first through hole 23 and the mounting hole 51. The first screw connects to the wall junction box, fixing the bottom shell 5 to the wall without disassembling the middle shell 2. After tightening the first screw, the button is snapped into the middle shell 2, completing the installation. If the position of the smart switch 100 needs to be fine-tuned, simply pry off the button and loosen the first screw to adjust the position without prying open the middle shell 2, thus avoiding damage to the wall.

[0117] Furthermore, such as Figure 9 and Figure 19 As shown, the first through holes 23 located on the left and right sides of the middle shell 2 interfere with the position of the elastic arm 221. In order to make the receiving bosses 222 on the left and right sides correspond to the position of the electronic switch 31 and to avoid interference between the elastic arm 221 and the first through hole 23, the elastic arm 221 on the left bends to the left and the elastic arm 221 on the right bends to the right.

[0118] Furthermore, such as Figure 9 As shown, there are four claws 1171, two of which are located between the two first through holes 23, and the other two are located outside the two first through holes 23.

[0119] In some embodiments, such as Figure 8 and Figures 13-15 As shown, the first circuit board 3 is provided with a light-emitting unit 32, the middle shell 2 has a first light-transmitting hole 24, and the bracket unit 111 has a second light-transmitting hole 1112 at the corresponding position of the first light-transmitting hole 24; the button cover 12 is made of a light-transmitting material, and its back is coated with a light-shielding layer. The light-shielding layer has a button pattern 121 laser-engraved at the corresponding position of the second light-transmitting hole 1112. The light emitted by the light-emitting unit 32 passes through the first light-transmitting hole 24, the second light-transmitting hole 1112 and the button pattern 121 and is then transmitted through the button cover 12.

[0120] The light-shielding layer includes a color layer facing the button cover 12 and a black paint layer facing the button bracket 11. The button cover 12 is made of glass. The color layer is used to give the button cover 12 its color, and the black paint layer is used to block light. The light-shielding layer is laser-engraved with hollowed-out text or patterns. Light passes through the hollowed-out text or patterns to form a luminous button pattern 121 on the button cover 12. In one embodiment, the button pattern 121 is constructed as three parallel circular holes. The button panel 14 is made of AG frosted glass, which has a slight light-diffusing effect.

[0121] Because the light-emitting unit 32 is very small, if it shines directly onto the button pattern 121, the button pattern 121 will appear bright in the center and dark around the edges. To ensure uniform illumination of the button pattern 121, a light-diffusing structure needs to be placed between the light-emitting unit 32 and the button pattern 121. However, conventional light-diffusing structures require a large light-diffusing space, which increases the thickness of the switch panel. In this embodiment, as... Figure 14 As shown, the middle shell 2 has a light source space 25 facing the first circuit board 3. The light-emitting unit 32 is located inside the light source space 25, and the first light-transmitting hole 24 is located to the side of the light source space 25. A light guide channel is provided between the light source space 25 and the first light-transmitting hole 24. The side of the first light-transmitting hole 24 facing the light-emitting unit 32 is an inclined reflective surface. The light emitted by the light-emitting unit 32 passes through the light guide channel and illuminates the light-emitting surface of the first light-transmitting hole 24. After being reflected by the reflective surface, it reaches the second light-transmitting hole 1112 and is finally transmitted through the button pattern 121. The light produces a uniform light effect during the reflection process, making the light transmitted through the button pattern 121 more uniform.

[0122] Furthermore, thanks to the first light-transmitting hole 24 being located to the side of the light-emitting unit 32, there is ample space for light to achieve a better uniform light effect, avoiding the need to increase the thickness of the middle shell 2 in the vertical direction. This solves the problem of uneven light emission of the button pattern 121 caused by insufficient space for uniform light distribution in the ultra-thin switch panel. The ultra-thin switch panel can be understood as follows: when the smart switch 100 is installed on the wall, the thickness of the components of the smart switch 100 located outside the wall is very thin, thus making the smart switch 100 appear ultra-thin. The switch panel can be understood as the part of the middle shell 2 and the button structure 1 located outside the wall.

[0123] In one embodiment, the light-emitting unit 32 may be an LED lamp.

[0124] Furthermore, white ink is screen-printed or a white film is pasted on the upper surface of the first circuit board 3 at the corresponding positions of the light source space 25 and the first light-transmitting hole 24, so that the first circuit board 3 appears white in that part, so as to avoid the first circuit board 3 reflecting colored light.

[0125] Furthermore, the second light-transmitting hole 1112 is constructed as a square through hole, and the button pattern 121 is located within the area of ​​the second light-transmitting hole 1112. For example... Figure 14 As shown, the size of the second light-transmitting hole 1112 is slightly larger than the size of the upper opening of the first light-transmitting hole 24.

[0126] Furthermore, such as Figure 2 and Figure 20 As shown, the button bracket 11 has a light-shielding rib 118 protruding towards the middle shell 2, such as... Figure 9 and Figure 14As shown, the upper surface of the middle shell 2 is provided with a light-shielding groove 26, and the light-shielding rib 118 is recessed into the light-shielding groove 26. Through the staggered cooperation of the light-shielding rib 118 and the light-shielding recess in the vertical direction, light cannot be transmitted from the side of the button, thus avoiding light leakage.

[0127] Furthermore, such as Figure 9 and Figure 14 As shown, a light-shielding ring protrudes from the upper surface of the middle shell 2 around the first light-transmitting hole 24, and the light-shielding ring surrounds the light outlet of the first light-transmitting hole 24; the light-shielding rib 118 is disposed on the outside of the light-shielding ring, and the light-shielding ring and the light-shielding rib 118 form an interlaced structure in the vertical direction to improve the light-shielding effect.

[0128] Furthermore, such as Figure 9 As shown, the side of the middle shell 2 facing the button bracket 11 has a first recess, and the first recess is further recessed to form a second recess. The reset member 22, the first light-transmitting hole 24, and a portion of the claws 1171 are located in the second recess, while another portion of the claws 1171 are located in the first recess. The first circuit board 3 is disposed on the side of the middle shell 2 opposite to the second recess and is located in the corresponding area of ​​the second recess, so that the switch panel is thinner.

[0129] Furthermore, the smart switch 100 also includes a bottom shell 5 and a first circuit board 3. The first circuit board 3 is disposed on the side of the middle shell 2 opposite to the button structure 1. The middle shell 2 covers the bottom shell 5 to form a first receiving cavity between the middle shell 2 and the bottom shell 5, and the first circuit board 3 is disposed inside the first receiving cavity. By recessing the first circuit board 3 into the bottom shell 5, the first circuit board 3 does not occupy the thickness of the switch panel, making the thickness of the switch panel exposed outside the wall thinner, providing users with an ultra-thin panel experience. Figures 18-22 In this embodiment, the first circuit board 3 integrates high-voltage and low-voltage circuits. Multiple third hooks 294 extend from the back of the middle shell 2, and these hooks 294 engage with the edges of the first circuit board 3, thereby confining the first circuit board 3 within the middle shell 2. A wireless communication module 33 and two electronic switches 31 are provided on the side of the first circuit board 3 facing the middle shell 2. The two electronic switches 31 are respectively positioned at the corresponding positions of the trigger posts 1111 of the buttons. A power module, a relay 41, and a terminal block 42 are provided on the side of the first circuit board 3 facing the bottom shell 5. The terminal block 42 is used to connect to high-voltage power. Figures 1-17In this embodiment, since the first circuit board 3 is provided with four electronic switches 31, and the four electronic switches 31 are distributed in pairs on both sides of the first circuit board 3, if the high-voltage circuit and the low-voltage circuit are integrated into the first circuit board 3, it will cause the position of the electronic switches 31 to interfere with the wiring terminal 42. Therefore, in this embodiment, a second circuit board 4 is also provided inside the bottom shell 5. The second circuit board 4 is located on the side of the first circuit board 3 away from the middle shell 2. The second circuit board 4 is used to carry the high-voltage circuit. The power module, relay 41 and wiring terminal 42 are located on the second circuit board 4. The first circuit board 3 is used to carry the low-voltage circuit. The wireless communication module 33 and the electronic switches 31 are located on the first circuit board 3.

[0130] like Figure 10 As shown, the number of relays 41 corresponds to the number of electronic switches 31. The relays 41 switch on and off in response to the electronic switches 31 being triggered. In one embodiment, the number of relays 41 and electronic switches 31 are both four, wherein the four relays 41 include two large relays 41 and two small relays 41.

[0131] Existing smart switches typically house the high-voltage board in the bottom shell and the low-voltage board in the middle shell. An isolation plate is installed inside the bottom shell, forming a cavity that encloses the high-voltage board, exposing only the sockets on the high-voltage board. The low-voltage board connects to these sockets via pin headers. During installation from the middle shell to the bottom shell, it's crucial to ensure the pin headers on the low-voltage board align with the sockets on the high-voltage board. However, because the bottom shell is fixed to the wall, the wall obstructs the user's view, making it difficult to see the pin headers and sockets. This results in misalignment, reducing installation efficiency. Furthermore, when the pin headers are misaligned, pressing the middle shell can easily bend or damage them.

[0132] To address the aforementioned problems, according to a second aspect of this utility model, an intelligent switch is provided, such as... Figures 1-17 As shown, the technical details of the smart switch will be explained in detail, such as... Figures 10-17As shown, the intelligent switch includes a bottom shell, a middle shell, a first circuit board, and a second circuit board. The middle shell covers the bottom shell, forming a first receiving cavity. The first circuit board carries a low-voltage circuit and is housed within the first receiving cavity. The second circuit board carries a high-voltage circuit and is housed within the first receiving cavity. The first and second circuit boards are respectively mounted on the middle shell, and then integrally mounted on the bottom shell. Specifically, before the middle shell 2 is installed onto the bottom shell 5, the first circuit board 3 and the second circuit board 4 are first installed onto the middle shell 2. The first circuit board 3 and the second circuit board 4 are electrically connected. The first circuit board 3, the second circuit board 4, and the middle shell 2 can be integrated into the bottom shell 5 as a whole. Compared with existing installation methods, this installation method provided by the present invention has the following advantages:

[0133] 1. The first circuit board 3, the second circuit board 4, and the middle shell 2 are all hand-operated during installation. The operator can flip the parts so that the view is not obstructed, which makes it easy for the pin header 43 to be aligned with the nut 34. This not only improves the installation efficiency, but also prevents the pin header 43 from being pressed crooked.

[0134] 2. After the middle shell 2 is installed into the bottom shell 5, the first circuit board 3 and the second circuit board 4 are sealed inside the bottom shell 5. When the user installs the smart switch 100 on the wall, there is no need to disassemble the middle shell 2. The user only needs to remove the button to install it, which makes the installation more convenient and avoids the user damaging the pin header 43.

[0135] 3. Compared to existing smart switches that place the circuit board on the bottom shell and indirectly connect it to the middle shell, this embodiment directly installs the first circuit board 3 and the second circuit board 4 on the middle shell 2. This shortens the dimensional chain between the first circuit board 3, the second circuit board 4 and the middle shell 2, ensuring higher relative positional accuracy among the three. Consequently, the relative position of the pin header 43 and the nut header 34 is more accurate, the connection is more stable, and the relative position of the reset component 22 and the electronic switch 31 is also more accurate, ensuring that the reset component 22 accurately triggers the electronic switch 31.

[0136] 4. When the bottom shell 5 is installed on the wall, if the screws are tightened too much, the bottom shell 5 will deform into the wall. Existing smart switches place the second circuit board on the bottom shell. Deformation of the bottom shell will cause the second circuit board to deform along with the bottom shell or move into the wall, which will lead to damage to the second circuit board or unstable connection between the second circuit board and the first circuit board. In this embodiment of the utility model, the first circuit board 3 and the second circuit board 4 are directly installed on the middle shell 2. Deformation of the bottom shell 5 will not affect the second circuit board 4, thus avoiding damage to the second circuit board 4 or unstable connection between the second circuit board 4 and the first circuit board 3.

[0137] 5. In the existing system, the second circuit board is sealed inside the bottom shell by an isolation plate. To remove the second circuit board, the middle shell and the isolation plate must be disassembled first. Since the second circuit board is embedded at the bottom of the bottom shell and is held in place by the snap-fit ​​mechanism of the bottom shell, it needs to be pried out with a tool, making disassembly difficult and causing the second circuit board to be troublesome to repair. In this embodiment of the utility model, the second circuit board 4 can be removed from the bottom shell 5 simply by removing the middle shell 2, making disassembly more convenient. Moreover, the second circuit board 4 can be repaired without being removed from the middle shell 2, greatly improving the convenience of repair.

[0138] Furthermore, such as Figures 15-17 As shown, the direction of the middle shell 2 toward the bottom shell 5 is set as a third direction. In the third direction, the middle shell 2, the first circuit board 3 and the second circuit board 4 are distributed in sequence. The middle shell 2 is provided with a first mounting part 27 and a second mounting part 28 in the third direction. The first circuit board 3 is detachably mounted on the first mounting part 27 and the second circuit board 4 is detachably mounted on the second mounting part 28.

[0139] Among them, the third party has already Figure 15 The winning bidder, in Figure 16 and Figure 17 To clearly demonstrate the connection relationships, the electronic components on the second circuit board 4 have been hidden, and only the connector 34 is visible on the first circuit board 3; other electronic components are also hidden. The first circuit board 3 can be connected to the first mounting part 27 via a snap-fit, screw connection, or other detachable connection method. The first mounting part 27 can be a hook, threaded connection post, or similar structure. Similarly, the second circuit board 4 can be connected to the second mounting part 28 via a snap-fit, screw connection, or other detachable connection method. The second mounting part 28 can be a hook, threaded connection post, or similar structure. During installation, the first circuit board 3 is first installed on the first mounting part 27, and then the second circuit board 4 is installed on the second mounting part 28. The sequential distribution of the middle shell 2, the first circuit board 3, and the second circuit board 4 along a third direction makes installation more convenient.

[0140] Furthermore, one of the first circuit board 3 and the second circuit board 4 is provided with a pin header 43, and the other is provided with a female header 34. The pin header 43 is inserted into the female header 34 to achieve electrical connection between the first circuit board 3 and the second circuit board 4. In one embodiment, as shown... Figure 15As shown, the lower surface of the first circuit board 3 is provided with the header 34, and the upper surface of the second circuit board 4 is provided with the header pins 43. When the second circuit board 4 is installed on the middle shell 2, the header pins 43 are inserted into the header 34, completing the electrical connection between the first circuit board 3 and the second circuit board 4, thus improving assembly efficiency. Since the installation sequence is to install the first circuit board 3 first and then the second circuit board 4, in this embodiment, placing the header pins 43 on the second circuit board 4 makes it easy to observe whether the header pins 43 are aligned with the header 34.

[0141] Furthermore, such as Figure 16 and Figure 17 As shown, the heights of the first mounting portion 27 and the second mounting portion 28 are matched to create a first gap H1 between the first circuit board 3 and the second circuit board 4, satisfying the relationship: 4mm ≤ H1 ≤ 9mm. The first gap H1 is used for electrical isolation between the first circuit board 3 and the second circuit board 4. The first gap H1 has already been... Figure 11 The first part is marked as "selected". In one embodiment, the second mounting part 28 supports the second circuit board 4 such that the first interval H1 satisfies the above relationship.

[0142] Furthermore, the side of the first circuit board 3 facing away from the second circuit board 4 is provided with a wireless communication module 33, a light-emitting unit 32, and an electronic switch 31. The side of the second circuit board 4 facing away from the first circuit board 3 is provided with a relay 41, a power module, and a terminal block 42. The power module is used to convert high-voltage electricity into low-voltage electricity. It is worth mentioning that the side of the first circuit board 3 facing the second circuit board 4 is only provided with the busbar 34 and a small resistor to avoid interference between the electronic components of the first circuit board 3 and the second circuit board 4.

[0143] In some embodiments, such as Figure 16 and Figure 17 As shown, the first mounting part 27 includes a first support part 271 and a first hook 272. The first support part 271 is used to abut against the first side of the first circuit board 3, and the first hook 272 is used to engage with the second side of the first circuit board 3. The first side can be understood as the side of the first circuit board 3 facing the middle shell 2, and the second side can be understood as the side of the first circuit board 3 away from the middle shell 2. The first circuit board 3 is clamped and limited in the vertical direction by the first support part 271 and the first hook 272.

[0144] The second mounting portion 28 includes a second support portion 281 and a second latch 282. The second support portion 281 is used to abut against the third side of the second circuit board 4, and the second latch 282 is used to latch onto the fourth side of the second circuit board 4. The third side can be understood as the side of the second circuit board 4 facing the middle shell 2, and the fourth side can be understood as the side of the second circuit board 4 facing away from the middle shell 2. The second circuit board 4 is vertically held and limited by the first support portion 271 and the first latch 272.

[0145] The advantage of using a snap-fit ​​connection between the first circuit board 3, the second circuit board 4 and the middle shell 2 is that during installation, the first circuit board 3 is first pressed into the first snap-fit ​​272, and then the second circuit board 4 is pressed into the second snap-fit ​​282 to complete the installation, which greatly improves the installation efficiency.

[0146] The length of the second hook 282 is the length of the first hook 272 plus the first interval H1 and the thickness of the second circuit board 4, and the height of the second support 281 is the height of the first support 271 plus the first interval H1 and the thickness of the second circuit board 4, so that the first interval H1 is formed between the first circuit board 3 and the second circuit board 4.

[0147] Furthermore, such as Figure 17 As shown, there are multiple first hooks 272, distributed at the first end and the second end of the first circuit board 3, with the first end and the second end facing each other, so that the first hooks 272 can stably limit the first circuit board 3 and facilitate the first circuit board 3 to be inserted into or removed from the first hooks 272; there are multiple second hooks 282, distributed at the third end and the fourth end of the second circuit board 4, with the third end and the fourth end facing each other, so that the second hooks 282 can stably limit the second circuit board 4 and facilitate the second circuit board 4 to be inserted into or removed from the second hooks 282.

[0148] The direction from the first end to the second end is perpendicular to the direction from the third end to the fourth end, thus providing more space for the first hook 272 and the second hook 282 to be arranged, making it easier to design the hook positions more reasonably. In one embodiment, the first end is provided with two first hooks 272, the second end is provided with two first hooks 272, the third end is provided with two second hooks 282, and the fourth end is provided with two second hooks 282.

[0149] In some embodiments, such as Figure 17As shown, the first support portion 271 includes a plurality of first support ribs, and the first support ribs and the first hook 272 are integrally formed in the middle shell 2; further, the first support ribs are disposed at the edge of the first circuit board 3. In one embodiment, the first support ribs include ribs around the edge of the first circuit board 3, thereby stably limiting the first circuit board 3.

[0150] like Figure 17 As shown, the second support portion 281 includes a plurality of second support ribs, and the second support ribs and the second hooks 282 are integrally formed on the middle shell 2; wherein, the second support ribs are distributed in the four corner areas of the second circuit board 4 and the corresponding positions of the wiring terminals 42.

[0151] like Figure 16 and Figure 17 As shown, the middle shell 2 extends two positioning posts 291 toward the third direction. The two positioning posts 291 are respectively located in the diagonal area of ​​the second circuit board 4. The positioning posts 291 are inserted into the second circuit board 4 to position the second circuit board 4. The positioning posts 291 located in the diagonal area of ​​the second circuit board 4 can improve the positioning accuracy, so that the relative position of the middle shell 2 and the second circuit board 4 in the horizontal direction is accurate.

[0152] Furthermore, such as Figure 17 As shown, the second supporting rib and / or the positioning post 291 positions the first circuit board 3, ensuring accurate relative positioning of the middle shell 2 and the first circuit board 3 in the horizontal direction. The second supporting rib and / or positioning post 291 can be understood as either the second supporting rib positioning the first circuit board 3, or the positioning post 291 positioning the first circuit board 3, or both the second supporting rib and the positioning post 291 jointly positioning the first circuit board 3. In one embodiment, the second supporting rib and the positioning post 291 simultaneously abut against the side of the first circuit board 3 to jointly position the first circuit board 3.

[0153] In one embodiment, such as Figure 17 As shown, the first circuit board 3 has second through holes 35 on both sides. The middle shell 2 has a threaded connecting post at the corresponding position of the second through hole 35. The second through hole 35 can be fixedly connected to the threaded connecting post by screws, so that the connection between the first circuit board 3 and the middle shell 2 is more stable.

[0154] In some embodiments, such as Figure 16 and Figure 17As shown, the middle shell 2 extends guide posts 292 from the four corner areas of the second circuit board 4 towards the third direction. The four guide posts 292 surround the second circuit board 4 and protrude from the second circuit board 4 towards the third direction, so that the second circuit board 4 is protected by the four guide posts 292, avoiding collision when the second circuit board 4 is placed into the bottom shell 5. The four guide posts 292 also have a guiding function, which can improve the efficiency of placing the second circuit board 4 into the bottom shell 5. Here, the four corner areas of the second circuit board 4 can be understood as the four areas near the four corners of the second circuit board 4.

[0155] Furthermore, such as Figure 16 As shown, the guide post 292 includes a first wall and a second wall extending along the third direction. The side of the first wall is connected to the side of the second wall, and the first wall and the second wall form a first angle. The corner of the second circuit board 4 is enclosed inside the first angle. This allows the guide post 292 to protect the second circuit board 4 while saving space. In a specific example, the first angle is a right angle.

[0156] In some embodiments, such as Figure 15 and Figure 7 As shown, the first circuit board 3 has a first surface facing the middle shell 2, and an electronic switch 31 is provided on the first surface. A button is provided on the side of the middle shell 2 opposite to the first circuit board 3. The button can be pressed to directly or indirectly trigger the electronic switch 31. In one embodiment, the trigger post 1111 of the button indirectly triggers the electronic switch 31 by driving the receiving boss 222. The elastic force of the elastic arm 221 is transmitted to the support unit 111 through the receiving boss 222 to provide a restoring force.

[0157] The button is the same as the button structure 1 provided in the first aspect of this utility model, and the middle shell 2 is the same as the middle shell 2 provided in the first aspect of this utility model. The technical details of the button and the middle shell 2 can be found above, and will not be repeated here.

[0158] When the base shell 5 is installed on the wall, if the screws are tightened too much, the base shell 5 may deform. To reduce the impact of the deformation of the base shell 5, in this embodiment of the utility model, such as Figure 10As shown, the bottom shell 5 has a first mounting side and a second mounting side arranged opposite to each other, as well as a first snap-fit ​​side and a second snap-fit ​​side arranged opposite to each other. The first mounting side and the second mounting side are respectively provided with mounting holes 51. The bottom shell 5 is mounted to a wall-mounted junction box through the mounting holes 51. The first snap-fit ​​side and the second snap-fit ​​side are respectively snapped into the middle shell 2. The direction of the first mounting side toward the second mounting side is perpendicular to the direction of the first snap-fit ​​side toward the second snap-fit ​​side. This reduces the impact of deformation of the first mounting side and the second mounting side on the middle shell 2. Thanks to the fact that the first circuit board 3 and the second circuit board 4 are both mounted on the middle shell 2, the deformation of the bottom shell 5 is avoided from having a direct impact on the first circuit board 3 and the second circuit board 4.

[0159] like Figure 10 As shown, the first snap-fit ​​side and the second snap-fit ​​side are respectively provided with a middle shell snap-fit ​​293, and the bottom shell 5 is provided with a snap-fit ​​position 52 adapted to the middle shell snap-fit ​​293. The first snap-fit ​​side and the second snap-fit ​​side are respectively snapped into the snap-fit ​​position 52 of the bottom shell 5 through the middle shell snap-fit ​​293.

[0160] In some embodiments, such as Figures 10-12 As shown, the system also includes multiple terminals 42, each terminal 42 comprising a conductive sheet 421 soldered to the second circuit board 4 and a locking assembly 422 disposed on the bottom shell 5. The bottom shell 5 has a wiring groove 53, and the locking assembly 422 is placed within the wiring groove 53. The locking assembly 422 includes a wiring screw 4221, which can be turned clockwise to clamp the conductive sheet 421, and can be turned counterclockwise to lock the locking assembly 422 into the wiring groove 53. When the locking assembly 422 is locked into the wiring groove 53, the conductive sheet 421 is not clamped by the locking assembly 422.

[0161] Locking the locking assembly 422 into the wiring slot 53 not only prevents the locking assembly 422 from coming off the wiring slot 53, but also facilitates the insertion of the conductive sheet 421 into the locking assembly 422. Thanks to the fact that the second circuit board 4 and the middle shell 2 are integrated into the bottom shell 5, when the operator installs the middle shell 2 into the bottom shell 5, the conductive sheet 421 automatically inserts into the locking assembly 422 along with the second circuit board 4, which can greatly improve the installation efficiency.

[0162] In one embodiment, such as Figure 12As shown, the locking assembly 422 includes a conductive sleeve 4222, a conductive plate 421 inserted into the conductive sleeve 4222, and a threaded hole on one side of the conductive sleeve 4222. A wiring screw 4221 is connected to the threaded hole and passes through it, abutting against the conductive plate 421. A wire is inserted into the conductive sleeve 4222 from below along the arrow in the diagram. Because the nut of the wiring screw 4221 is restricted from movement by the ribs inside the wiring groove 53, when the wiring screw 4221 is turned clockwise, the conductive sleeve 4222 moves to the left, causing the wire and conductive plate 421 to be clamped between the wiring screw 4221 and the right wall of the conductive sleeve 4222, thus connecting the conductive plate 421 to the external wire. When the wiring screw 4221 is turned counterclockwise, the conductive sleeve 4222 moves to the right, as shown in the diagram. Figure 12 As shown, at this time, the right wall of the conductive sleeve 4222 abuts against the right wall of the wiring groove 53, and the conductive sleeve 4222 is subjected to a leftward abutting force. The wiring screw 4221 abuts against the rib at the left end of the wiring groove 53, and the wiring screw 4221 is subjected to a rightward abutting force. The left and right abutting forces cause the wiring screw 4221 and the conductive sleeve 4222 to be locked in the wiring groove 53.

[0163] Furthermore, the intelligent switch 100 is similar to the one provided in the first aspect of this utility model. Figures 1-17 The structure of the smart switch 100 in the illustrated embodiment is the same. Other technical details of the smart switch 100 can be found in the description of the first aspect of this utility model, and will not be repeated here.

[0164] According to a third aspect of this utility model, such as Figures 23-26 As shown, a smart switch 100 with an integrated button is provided. Compared with this embodiment, Figures 1-17 The illustrated embodiment differs in that:

[0165] 1. The button bracket 11 and the button cover 12 are combined into a button panel 14. The button panel 14 is integrally formed of plastic material. At this time, the button structure 1 is the button panel 14. The back of the button panel 14 is provided with reinforcing ribs to enhance its resistance to deformation.

[0166] 2. The second light-transmitting hole 1112 of the button passes through the button panel 14, and the light-emitting unit 32 is set in the position directly opposite the first light-transmitting hole 24 of the middle shell 2. The light emitted by the light-emitting unit 32 passes through the first light-transmitting hole 24 and the second light-transmitting hole 1112 to illuminate the outside.

[0167] 3. The shapes of the first light-transmitting hole 24 and the second light-transmitting hole 1112 have changed. The first light-transmitting hole 24 is a square through hole, and the second light-transmitting hole 1112 is a conical through hole that is smaller at the top and larger at the bottom. The second light-transmitting hole 1112 presents a very small light-emitting area on the button panel 14.

[0168] 4. The electronic switch 31 has been replaced by a tactile switch instead of a micro switch.

[0169] Among them, such as Figure 24 As shown, the connecting part 112 is integrally formed on the button panel 14. The button panel 14 is divided into a left button and a right button by a first gap 113. The width of the first gap 113 on the front of the button panel 14 is smaller than its width on the back of the button panel 14. The first gap 113 on the back of the button panel 14 is divided into two parts by the connecting part 112. A connecting groove 141 is formed on the front of the button panel 14 at the corresponding position of the connecting part 112. The connecting groove 141 connects the two parts of the first gap 113. In a first direction, the width of the connecting groove 141 is equal to the width of the first gap 113 on the front of the button panel 14, so that the first gap 113 and the connecting groove 141 form a complete seam on the front of the button panel 14.

[0170] Furthermore, the side of the connecting part 112 facing the middle shell 2 is flush with the side of the button panel 14 facing the middle shell 2.

[0171] In this embodiment, the button panel 14 no longer has the second gap 1141. Thanks to the button panel 14 being integrally molded from plastic material, which has good deformation properties, when a button is pressed and triggers the electronic switch 31, it can avoid adjacent buttons triggering the electronic switch 31 in a coordinated manner.

[0172] Apart from the differences mentioned above, this embodiment is similar to... Figures 1-17 The other structures in the illustrated embodiments are the same. The technical details of the other structures have been described in detail above and can be referred to the above description. They will not be repeated here.

[0173] 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.

[0174] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
