Description

Technical Field

[0001] This invention relates to the field of switch technology, and more particularly to an intelligent switch. Background Technology

[0002] With the rapid development of smart homes, smart switches, as an important component of smart homes, have received increasing attention. Smart switches can provide users with a convenient and efficient living experience, such as remotely controlling home lights and appliances, turning off lights with a single button, and intelligently linking with other devices.

[0003] Existing smart switches have panels with some structural features that could be improved. Summary of the Invention

[0004] Existing smart switches with integrated buttons typically arrange the buttons in one direction, connecting them side-by-side. A pivoting claw is located near the connection point, engaging with the inner shell. This claw provides constraint to the button's rotational joint, limiting its movement to pivoting motion. This results in poor button flexibility; the end of the button furthest from the pivoting claw is easier to press, while pressing other areas makes it difficult to trigger the electronic switch. Therefore, existing integrated buttons cannot achieve multi-directional tilting or large-area pressing, affecting the tactile feel and ease of use.

[0005] To address the aforementioned problems, one objective of this invention is to provide an intelligent switch in which a connecting part connects all buttons into a single unit, thereby precisely limiting the positional relationship between the buttons, ensuring the consistency of the gaps between the buttons, and improving the relative positional accuracy between the buttons and the inner shell.

[0006] Another objective of this invention is to provide an intelligent switch in which the button moves around each limiting area as a fulcrum, and the button can tilt toward each pressed angle, greatly improving the button's flexibility and the pressing feel; and each limiting area corresponds to a fulcrum for each pressing angle, and each pressing angle, trigger part and corresponding limiting area form a lever-like structure, ensuring that pressing each pressing angle can trigger the electronic switch, and increasing the pressable area of ​​the button.

[0007] Another objective of this invention is to provide an intelligent switch in which the pressing angle is set at a position away from the connecting part of the button, while no pressing angle is set at the position of the button near the connecting part. This avoids the button being pressed near the connecting part, which could cause the buttons to be linked and the electronic switch to be accidentally triggered. This provides conditions for the organic integration of integrated button technology and large-area pressing technology.

[0008] Another objective of this invention is to provide an intelligent switch in which the elastic arm not only provides a reset force for the button, but also provides a supporting force for the button, so as to prevent the adjacent button from being pressed down in conjunction when a button is pressed, thus preventing the electronic switch from being accidentally triggered; and the supporting force of the elastic arm can make the button pressing feel more resilient, avoiding a soft and limp pressing feel.

[0009] Another objective of this invention is to provide an intelligent switch in which the elastic arm is in a pre-compressed state when the button is not pressed, so that the elastic arm provides elastic support at all times, preventing the button from becoming loose.

[0010] Another objective of this invention is to provide an intelligent switch in which, when the electronic switch is triggered, the vibration of the electronic switch cannot be directly transmitted longitudinally to the button, but must be transmitted laterally through an elastic arm before it can be transmitted to the button. The elastic arm is elastic and can buffer the vibration of the electronic switch, thereby improving the pressing feel of the button.

[0011] Another objective of this invention is to provide an intelligent switch in which the limiting area is located in the area of ​​the button bracket that is diagonally distributed with each pressing angle, thereby ensuring that the user can successfully trigger the electronic switch by pressing each pressing angle.

[0012] Another objective of this invention is to provide an intelligent switch in which the connecting part is located at the center of four buttons, such that each button is connected to the connecting part at only one corner, which reduces the linkage between the buttons. Moreover, since each button is connected to the connecting part at only one corner, the three corners of the button away from the connecting part are pressing corners, and all three pressing corners can be pressed to trigger the electronic switch, thereby increasing the pressing area of ​​the button.

[0013] Another objective of this invention is to provide an intelligent switch in which the buttons are distributed at the four corners, making the shape of the buttons more square and better suited to the characteristics of large-area button pressing.

[0014] Another objective of this invention is to provide an intelligent switch in which the small area of ​​the button bracket allows the button bracket to sink into the first recess of the middle shell, which is beneficial for achieving an ultra-thin panel. The button bracket is arranged in the area of ​​the button panel near the connecting part, so that the button brackets of each button can be connected together by the connecting part.

[0015] Another objective of this invention is to provide an intelligent switch in which the area of ​​the button panel near the connection part cannot be pressed, so as to avoid the electronic switch being accidentally triggered due to the linkage between the buttons.

[0016] Another objective of the present invention is to provide an intelligent switch in which the corners of the button bracket that are diagonally distributed with the connecting portion are not provided with snap-fit ​​portions, thereby simplifying the structure of the button bracket and the middle shell, so that the button bracket can sink into the first recess of the middle shell.

[0017] Another object of the present invention is to provide an intelligent switch in which the connecting part is supported by the middle shell, and the area of ​​the button bracket near the connecting part is supported by the middle shell, so that the area of ​​the button panel near the connecting part cannot be pressed.

[0018] Another object of the present invention is to provide an intelligent switch, wherein the first circuit board has an avoidance portion for avoiding the button hook.

[0019] Another objective of this invention is to provide an intelligent switch in which the position of the connecting part is fixed, thereby preventing the connecting part and the button from shaking and causing the button to become loose, while making the positional relationship between the button and the middle shell more accurate, and ensuring that the gap width between each button and the display cover is consistent.

[0020] Another objective of this invention is to provide an intelligent switch in which the connecting part is clamped and fixed by the display cover and the middle shell, eliminating the need for additional design of a structure for fixing the connecting part, making the structure more compact and facilitating the realization of an ultra-thin panel; at the same time, assembly efficiency is improved.

[0021] Another objective of this invention is to provide an intelligent switch in which each screen displays button information for two buttons, thereby saving the number of screens, making the structure more compact, and leaving more space for the buttons to ensure their area.

[0022] To achieve at least one of the above objectives, the present invention provides an intelligent switch, comprising a middle shell, a first circuit board, multiple buttons, and a connecting portion; the first circuit board is disposed in the middle shell and has multiple electronic switches; each button corresponds to each electronic switch, and each button has a trigger portion for directly or indirectly triggering the electronic switch; the connecting portion connects the buttons into a whole; multiple corners of the buttons away from the connecting portion are set as pressing angles, and each pressing angle forms a corresponding limiting area on the edge region of the button in the direction of the trigger portion; the trigger portion is located between each pressing angle and the corresponding limiting area; when a pressing angle is pressed, the limiting area corresponding to the pressing angle is limited by the middle shell and cannot be tilted upward, so that the trigger portion triggers the electronic switch.

[0024] In some embodiments, each button includes a button plate and a button bracket. The button bracket is connected to the middle shell, and the connecting portion connects each button bracket as a whole. The button plate is integrally formed or fixedly connected to the button bracket. The limiting region is located in the area of ​​the button bracket that is diagonally distributed with each pressing angle.

They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0061] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0062] In the description of this invention, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by the present invention.

[0064] Existing smart switches with integrated buttons typically arrange the buttons in one direction, connecting them side-by-side. A pivoting claw is located near the connection point, engaging with the inner shell. This claw provides constraint to the button's rotational joint, limiting its movement to pivoting motion. This results in poor button flexibility; the end of the button furthest from the pivoting claw is easier to press, while pressing other areas makes it difficult to trigger the electronic switch. Therefore, existing integrated buttons cannot achieve multi-directional tilting or large-area pressing, affecting the tactile feel and ease of use.

[0065] To address the above problems, this invention provides an intelligent switch 100. Please refer to [link / reference]. Figures 1-23 The intelligent switch 100 provided by this invention will be specifically explained. For example, Figure 12 as well as Figures 8-10 As shown, the smart switch 100 includes a middle shell 3, a first circuit board 4, multiple buttons 1, and a connecting part 2. The first circuit board 4 is disposed on the middle shell 3 and has multiple electronic switches 41. Each button 1 corresponds to a specific electronic switch 41. Each button 1 has a trigger part 131 for directly or indirectly triggering the electronic switch 41. The connecting part 2 connects the buttons 1 into a whole, so that the positional relationship between the buttons 1 is precisely limited by the connecting part 2, thereby ensuring the consistency of the gaps between the buttons 1 and improving the relative positional accuracy between the buttons 1 and the middle shell 3. The electronic switches 41 can be tactile switches, micro switches, detection switches, or other electronic switches 41. In the exemplary embodiment, the electronic switches 41 are tactile switches.

[0066] like Figure 9 and Figure 10 As shown, where Figure 10 This is a partial structural diagram of a button 1 and a connecting part 2. The purpose is to facilitate observation of the structure of button 1. Figure 10 The left button 1 is hidden, and only the right button 1 is shown. Multiple corners of the button 1 away from the connecting part 2 are set as pressing angles 11. Each pressing angle 11 forms a corresponding limiting area 12 on the edge region of the button 1, facing the trigger part 131. The trigger part 131 is located between each pressing angle 11 and the corresponding limiting area 12. When a pressing angle 11 is pressed, the limiting area 12 corresponding to that pressing angle 11 is limited by the middle shell 3 and cannot tilt upwards, making the limiting area 12 the fulcrum for the movement of the button 1, ensuring that the trigger part 131 triggers the electronic switch 41. Unlike the pivotal movement of existing integrated buttons, the button 1 provided in this embodiment moves around each limiting area 12 as a fulcrum. The button 1 can tilt toward each pressed pressing angle 11, greatly improving the flexibility of the button 1 and the pressing feel. Furthermore, each limiting area 12 corresponds to a fulcrum for each pressing angle 11, and each pressing angle 11, trigger part 131, and corresponding limiting area 12 form a lever-like structure, ensuring that pressing each pressing angle 11 can trigger the electronic switch 41, increasing the pressable area of ​​the button 1. This solves the problems in the prior art.

[0067] The corners of button 1 can be understood as the positions where the two edges of button 1 intersect. For example, a rectangular button 1 has four corners, two, three, or all four of which can be pressing corners 11. The number of pressing corners 11 is related to the position of the connecting part 2. For example, when the connecting part 2 is located in the area of ​​one corner of the rectangular button 1, the other three corners of the button 1 can all be used as pressing corners 11. For example, when the connecting part 2 is located in the area of ​​an entire side of the rectangular button 1, the two corners of the button 1 away from that side can all be used as pressing corners 11. For example, when the connecting part 2 is located in the middle of one side of the rectangular button 1 and the connecting part 2 is very narrow, all four corners of the button 1 can be used as pressing corners 11.

[0068] It is worth noting that in this embodiment of the invention, the pressing angle 11 is set at the position of the button 1 away from the connecting part 2, while the pressing angle 11 is not set at the position of the button 1 near the connecting part 2. This avoids the button 1 being accidentally triggered due to the linkage between the buttons when the position near the connecting part 2 is pressed, thus providing conditions for the organic integration of integrated button technology and large-area pressing technology.

[0069] The connection part 2 connects each button 1 into a whole, which can be understood as the connection part 2 and the button 1 being integrally formed or fixedly connected as a whole. The trigger part 131 can directly abut against the electronic switch 41 to directly trigger the electronic switch 41, or it can indirectly trigger the electronic switch 41 by driving other components.

[0070] The number of buttons 1 can be 2, 3, 4 or more, and the buttons 1 can be arranged side by side in one direction (e.g. Figure 22 The illustrated embodiment can also be arranged in a matrix with multiple rows and columns (e.g., Figure 1 (The example shown).

[0071] The limiting area 12 corresponding to the pressing angle 11 can be understood as, for example, Figure 10 As shown, a straight line is drawn from the pressing angle 11 toward the trigger part 131. The area near the intersection of this straight line and the edge of the button 1 forms the limiting area 12. Each pressing angle 11 forms a corresponding limiting area 12. Figure 10 In the diagram, the limiting region 12 is marked with a dashed box. The limiting region 12 can be understood as a relatively large area, including not only the area that is linearly distributed with the trigger part 131 and the pressing angle 11, but also the area that deviates slightly from the linear distribution. As long as the limiting region 12 forms an approximately linear relationship with the trigger part 131 and the pressing angle 11, it is within the protection scope of this invention.

[0072] In one embodiment, the limiting region 12 is set as a rectangular region with a side length greater than 6 mm and less than 14 mm.

[0073] The limiting region 12 is limited by the middle shell 3 in a manner that can be snap-fit ​​limiting, abutting limiting, or other limiting methods that can prevent the limiting region 12 from tilting upwards. The specific limiting methods are described in detail below.

[0074] Furthermore, such as Figure 8 , Figure 11 , Figure 12 As shown, the middle shell 3 is provided with a reset member, which provides a reset force for the button 1. The button 1 and the first circuit board 4 are disposed on both sides of the middle shell 3. The reset member includes an elastic arm 31, which is disposed between the trigger part 131 and the electronic switch 41. The trigger part 131 is constructed as a trigger post, which abuts against the elastic arm 31, thereby triggering the electronic switch 41 through the elastic arm 31. Specifically, the trigger part 131 abuts against the upper surface of the elastic arm 31, and the lower surface of the elastic arm 31 abuts against the trigger button 411 of the electronic switch 41. The trigger part 131 presses down on the elastic arm 31, causing the elastic arm 31 to undergo downward elastic deformation, thereby pressing the trigger button 411 of the electronic switch 41, thus triggering the electronic switch 41.

[0075] The elastic arm 31 not only provides a reset force for button 1, but also provides a supporting force for button 1, preventing adjacent buttons from being pressed down and causing the electronic switch 41 to be accidentally triggered when one button 1 is pressed. Furthermore, the supporting force of the elastic arm 31 makes the button 1 more resilient to press, preventing it from feeling soft and limp.

[0076] It is worth mentioning that when button 1 is not pressed, the elastic arm 31 is in a pre-compressed state, so that the elastic arm 31 provides elastic support at all times, so that button 1 will not be loose.

[0077] like Figure 11 As shown, the trigger part 131 and the trigger button 411 of the electronic switch 41 respectively abut against different sections of the elastic arm 31. The abutting positions of the two are marked with dashed lines in the figure. As can be seen from the figure, the position of the trigger part 131 and the position of the trigger button 411 are offset in the horizontal direction. When the electronic switch 41 is triggered, the vibration of the electronic switch 41 cannot be directly transmitted longitudinally to the button 1. It must be transmitted laterally through the elastic arm 31 to be transmitted to the button 1. The elastic arm 31 is elastic and can buffer the vibration of the electronic switch 41, thereby improving the pressing feel of the button 1. Even if the electronic switch 41 uses a hard button, its vibration can be effectively buffered.

[0078] In some embodiments, the trigger button 411 of the electronic switch 41 is a rigid button. Although the rigid button produces a stronger vibration when the electronic switch 41 is triggered, the elastic arm 31 provides excellent cushioning, effectively reducing vibration transmission. This allows the electronic switch 41 with the rigid button, in conjunction with the elastic arm 31, to still provide a good tactile feel for button 1. Using a rigid button not only results in a shorter trigger stroke but also better consistency in the trigger stroke. That is, the trigger stroke of electronic switches 41 produced in different batches fluctuates less, which is beneficial for precise control of the button 1's stroke and provides a structural basis for the implementation of ultra-thin panels. The rigid material can be understood as a material that is not easily compressed macroscopically, such as plastic, iron, brass, aluminum alloy, etc. In one embodiment, the electronic switch 41 is a tactile switch, and the rigid button is made of brass.

[0079] The panel of the smart switch 100 can be understood as the part located on the outside of the wall when the smart switch 100 is installed on the wall.

[0080] Furthermore, since a portion of the travel of button 1 is consumed by the deformation of the elastic arm 31, the effective travel of button 1 is shortened, and there is a risk that button 1 may fail to trigger the electronic switch 41 within its effective travel. Therefore, in this embodiment of the invention, as... Figure 11 As shown, the elastic arm 31 includes a fixed end connected to the middle shell 3. Along the extending direction of the elastic arm 31, the fixed end, the trigger part 131, and the trigger button 411 are sequentially distributed. Thus, the elastic arm 31 forms a lever that requires more effort. The stroke of the trigger part 131 is amplified at the location of the trigger button 411, thereby compensating for the stroke loss caused by the deformation of the elastic arm 31 and ensuring that the button 1 can trigger the electronic switch 41 within its effective stroke.

[0081] Furthermore, such as Figure 11 As shown, the extension direction of the elastic arm 31 is a curved direction.

[0082] In some embodiments, such as Figures 8-10 as well as Figures 20-21 As shown, each button 1 includes a button plate 14 and a button bracket 13. The button bracket 13 is connected to the middle shell 3, and the connecting part 2 connects each button bracket 13 into one unit. The button plate 14 is integrally formed or fixedly connected to the button bracket 13; wherein, in Figures 8-10 In this embodiment, the button panel 14, the button bracket 13, and the connecting part 2 are integrally injection molded from plastic material. Figures 20-21 In this embodiment, the button bracket 13 and the connecting part 2 are integrally injection molded from plastic material, and the button plate 14 is made of glass material, and the button plate 14 is pasted and fixed to the upper surface of the button bracket 13.

[0083] like Figure 10 As shown, the limiting area 12 is located in the area of ​​the button bracket 13 that is diagonally distributed with each of the pressing angles 11. The button bracket 13 is provided with a locking part 132 in the limiting area 12. The locking part 132 is locked with the middle shell 3 to limit the extreme position of the upward movement of the limiting area 12, thereby ensuring that the user can successfully trigger the electronic switch 41 by pressing each pressing angle 11. The area of ​​the button bracket 13 that is diagonally distributed with each pressing angle 11 can be understood as follows: the upper left corner of the button bracket 13 is diagonally distributed with the lower right corner of the button plate 14, the upper right corner of the button bracket 13 is diagonally distributed with the lower left corner of the button plate 14, and the lower left corner of the button bracket 13 is diagonally distributed with the upper right corner of the button plate 14.

[0084] The limiting area 12 can be located exactly at the corner of the button bracket 13, or slightly off the corner of the button bracket 13. The locking part 132 can be located at the center of the limiting area 12, or at the edge of the limiting area 12. The locking part 132 can be a hook, a step, or other structure capable of locking.

[0085] Furthermore, such as Figures 8-10 as well as Figures 20-21 As shown, the button bracket 13 protrudes from the back of the button plate 14.

[0086] Furthermore, such as Figure 6 and Figure 9 As shown, there are four buttons 1, which are distributed at four corners around the connecting part 2. The connecting part 2 is positioned at the center of the four buttons 1, so that each button 1 is connected to the connecting part 2 at only one corner, reducing the linkage between the buttons 1. Furthermore, since each button 1 is connected to the connecting part 2 at only one corner, the three corners of the button 1 furthest from the connecting part 2 are all pressing corners 11, which can all be pressed to trigger the electronic switch 41, thus increasing the pressing area of ​​the button 1.

[0087] It is worth mentioning that, compared to arranging the four buttons 1 along a straight line, which results in the buttons 1 having an elongated shape, the buttons 1 in this embodiment are distributed at the four corners, making the shape of the buttons 1 more square and more suitable for the large area of ​​the buttons 1 to be pressed.

[0088] Furthermore, such as Figure 6 As shown, the four buttons 1 are located at the upper left, upper right, lower left, and lower right corners of the connecting part 2, respectively. Two buttons 1 are arranged side by side at the upper end of the connecting part 2, and the other two buttons 1 are arranged side by side at the lower end of the connecting part 2.

[0089] Furthermore, such as Figure 10As shown, the button panel 14 is rectangular, including a first pressing angle 111 diagonally distributed with respect to the connecting portion 2, and a second pressing angle 112 and a third pressing angle 113 adjacent to the connecting portion 2. The first pressing angle 111, the second pressing angle 112, the third pressing angle 113, and the connecting portion 2 are distributed in the four corner areas of the button panel 14. The button bracket 13 includes a first limiting area 121 diagonally distributed with respect to the first pressing angle 111, a second limiting area 122 diagonally distributed with respect to the second pressing angle 112, and a third limiting area 123 diagonally distributed with respect to the third pressing angle 113. The trigger portion 131 is located between the first pressing angle 111 and the first limiting area 121, between the second pressing angle 112 and the second limiting area 122, and between the third pressing angle 113 and the third limiting area 123. The first limiting area 121, the second limiting area 122, and the third limiting area 123 have been... Figure 10 The area is marked with a dashed box. It can be understood that the pressing angle 11 includes the first pressing angle 111, the second pressing angle 112, and the third pressing angle 113, and the limiting area 12 includes the first limiting area 121, the second limiting area 122, and the third limiting area 123.

[0090] In some embodiments, such as Figure 9 and Figure 10 As shown, the area of ​​the button bracket 13 is smaller than the area of ​​the button plate 14, and the button bracket 13 is arranged in a region of the button plate 14 near the connecting part 2. The smaller area of ​​the button bracket 13 allows it to sink into the first recess 38 of the middle shell 3, which is beneficial for achieving an ultra-thin panel. The arrangement of the button bracket 13 in the region of the button plate 14 near the connecting part 2 allows the button brackets 13 of each button 1 to be connected as a single unit by the connecting part 2.

[0091] In some embodiments, such as Figure 9 As shown, the area of ​​the button plate 14 near the connecting part 2 cannot be pressed to avoid the electronic switch 41 being accidentally triggered due to the linkage between the buttons 1; correspondingly, the corners of the button bracket 13 that are diagonally distributed with the connecting part 2 are not provided with the snap-fit ​​part 132, thereby simplifying the structure of the button bracket 13 and the middle shell 3, so that the button bracket 13 can sink into the first recess 38 of the middle shell 3.

[0092] In other embodiments, although the area of ​​the keypad 14 near the connecting portion 2 cannot be pressed, the corners of the keypad bracket 13 that are diagonally distributed with respect to the connecting portion 2 are still provided with snap-fit ​​portions 132.

[0093] In some embodiments, such as Figures 7-9As shown, the connecting portion 2 is supported by the middle shell 3, and the area of ​​the button bracket 13 near the connecting portion 2 is also supported by the middle shell 3, so that the area of ​​the button plate 14 near the connecting portion 2 cannot be pressed. In an exemplary embodiment, the area of ​​the button bracket 13 near the connecting portion 2 is set as a support area 134, and the middle shell 3 is provided with a support portion 32 at a corresponding position of the support area 134. The support portion 32 is used to support the support area 134. The support area 134 can be a small area or a large area. In an exemplary embodiment, the support area 134 has been... Figure 9 The text is marked with a dashed box. Further, such as... Figure 7 As shown, the support portion 32 is constructed as a support protrusion, and there are four support protrusions, which respectively abut against the support area 134.

[0094] In some embodiments, such as Figure 8 and Figure 9 As shown, the latching part 132 includes a button latch 1321, and the middle shell 3 is provided with a latching position 33 at the corresponding position of the button latch 1321. The button latch 1321 is latched into the latching position 33, and the button latch 1321 can move downward in response to the button 1 being pressed.

[0095] Furthermore, the latching portion 132 also includes a button latch 1322, which is disposed in the area of ​​the button bracket 13 near the connecting portion 2. The middle shell 3 has a latching position 33 corresponding to the button latch 1322, and the button latch 1322 latches into the latching position 33. Since the area of ​​the button plate 14 near the connecting portion 2 cannot be pressed, the button latch 1322 cannot move towards the middle shell 3. Figure 9 As shown, there are two button clips 1322, located at the upper and lower ends of the connecting part 2 respectively. The two buttons 1 at the upper end of the connecting part 2 share one button clip 1322, and the two buttons 1 at the lower end of the connecting part 2 share another button clip 1322.

[0096] Furthermore, such as Figure 8 and Figure 9 As shown, the latching part 132 further includes a latching plate 1323. The middle shell 3 has a latching position 33 at a corresponding position of the latching plate 1323. The latching plate 1323 latches into the latching position 33, and the latching plate 1323 can move downward in response to the button 1 being pressed. The latching plate 1323 is thinner, making it less likely to interfere with the first circuit board 4 when moving downward. Furthermore, the latching plate 1323 occupies less thickness of the panel, which is beneficial for achieving an ultra-thin panel.

[0097] Furthermore, such as Figure 13 and Figure 17 As shown, the first circuit board 4 is disposed on the side of the middle shell 3 opposite to the button 1. The first circuit board 4 has a relief portion 42 at the position corresponding to the button hook 1321. The relief portion 42 is used to avoid the button hook 1321. Further, the relief portion 42 is constructed as a groove formed on the edge of the first circuit board 4, and the bottom of the button hook 1321 is located inside the relief portion 42.

[0098] Furthermore, such as Figure 13 As shown, the first circuit board 4 has an avoidance part 42 at the position corresponding to the button buckle 1322. The avoidance part 42 is used to avoid interference between the first circuit board 4 and the button buckle 1322. Furthermore, the avoidance part 42 corresponding to the button buckle 1322 is constructed as an opening.

[0099] like Figure 1 As shown, the middle shell 3 is covered by a display cover plate 5. A screen 6 is provided in the area covered by the display cover plate 5. The display content of the screen 6 is displayed to the outside through the display cover plate 5. The display cover plate 5 is long and rectangular. The display cover plate 5 is arranged horizontally. Two buttons 1 are located on one side of the display cover plate 5, and two other buttons 1 are located on the other side of the display cover plate 5. The display cover plate 5 and the buttons 1 are arranged side by side.

[0100] like Figure 10 As shown, the button hook 1321 is located at the end of the button bracket 13 opposite to the display cover 5, and in a corner area adjacent to the connecting part 2. The latching plate 1323 is located at the end of the button bracket 13 near the display cover 5, and in a corner area adjacent to the connecting part 2. The button latch 1322 is located at a corner of the button bracket 13 near the connecting part 2.

[0101] In some embodiments, such as Figures 1-5 As shown, the display cover 5 and the four buttons 1 are arranged side by side. The display cover 5 covers the connecting part 2, and the connecting part 2 is clamped and fixed by the display cover 5 and the middle shell 3. The fixed position of the connecting part 2 prevents the buttons 1 from becoming loose due to movement between the connecting part 2 and the buttons 1, and also ensures a more accurate positional relationship between the buttons 1 and the middle shell 3, guaranteeing a consistent gap width between each button 1 and the display cover 5.

[0102] It is worth mentioning that the connecting part 2 is clamped and fixed by the display cover plate 5 and the middle shell 3, eliminating the need for an additional fixing structure for fixing the connecting part 2, making the structure more compact and conducive to achieving an ultra-thin panel; at the same time, the assembly efficiency is improved.

[0103] Furthermore, such as Figure 1 and Figure 2As shown, four buttons 1 are arranged in pairs on both sides of the display cover 5. There are two screens 6, and the connecting part 2 passes between the two screens 6. Each screen 6 displays the button information of two buttons 1, thus saving the number of screens 6, making the structure more compact, and leaving more space for the buttons 1 to ensure their area. The display cover 5 is a horizontally arranged strip shape, with two buttons 1 located on the upper side of the display cover 5 and the other two buttons 1 located on the lower side. The two screens 6 are arranged left and right. The left screen 6 displays two lines of text or patterns to indicate the functions of the upper left and lower left buttons 1; the right screen 6 displays two lines of text or patterns to indicate the functions of the upper right and lower right buttons 1.

[0104] Existing smart switches with integrated buttons typically arrange the buttons in one direction and connect them side by side, resulting in obvious linkage between the buttons and poor button flexibility.

[0105] To address the above problems, in some embodiments, such as Figures 1-2 As shown, the smart switch 100 includes a middle shell 3, a screen 6, a display cover 5, and multiple buttons 1. The screen 6 is disposed on the middle shell 3. The display cover 5 covers the middle shell 3, and the screen 6 is located within the coverage area of ​​the display cover 5. The display content of the screen 6 is displayed externally through the display cover 5. The buttons 1 are disposed on the middle shell 3, and the buttons 1 are arranged side by side with the display cover 5. The connecting part 2 connects the multiple buttons 1 into a whole. The connecting part 2 is disposed on the side of the buttons 1 facing the display cover 5. The connecting part 2 is covered by the display cover 5 and is clamped by the display cover 5 and the middle shell 3.

[0106] In this embodiment of the invention, the connecting part 2 is disposed on the side of the button 1 facing the display cover plate 5, which can reduce the linkage between the buttons 1 and improve the flexibility of the buttons 1. Furthermore, the connecting part 2 is clamped by the display cover plate 5 and the middle shell 3, eliminating the need for an additional fixing structure for fixing the connecting part 2, making the structure more compact and facilitating the realization of an ultra-thin panel; at the same time, assembly efficiency is improved.

[0107] The buttons 1 can be arranged side-by-side in one direction or in a matrix arrangement with multiple rows and columns. In some embodiments, such as Figure 22 and Figure 23 As shown, when the buttons 1 are arranged side by side in one direction, each button 1 is located on the same side of the display cover 5, and the connecting part 2 is disposed on the side of each button 1 facing the display cover 5. In other embodiments, such as Figure 1 and Figure 2As shown, when the buttons 1 are arranged in a matrix of two rows and two columns, the display cover 5 is horizontally arranged between the two rows of buttons 1. There are four buttons 1, distributed at the four corners. The four buttons 1 are paired up on the first and second sides of the display cover 5, with the first and second sides being opposite sides. The connecting part 2 extends from the first side to the second side. Further, there are four buttons 1, with two buttons 1 located on the upper side of the display cover 5 and the other two buttons 1 located on the lower side of the display cover 5. The upper end of the connecting part 2 is connected to the upper buttons 1, and the lower end of the connecting part 2 is connected to the lower buttons 1.

[0108] Furthermore, the connecting portion 2 is located between the two screens 6. For example, as shown... Figure 22 and Figure 23 As shown, when there are two buttons 1, there are also two screens 6, each screen 6 corresponding to one side of each button 1, and the connecting part 2 is located between the two screens 6, arranged side by side with the screens 6; when there are three buttons 1 (not shown in the figure of this embodiment), there are also three screens 6, each screen 6 corresponding to one side of each button 1, and there are two connecting parts 2, with the connecting parts 2 arranged between each pair of the three screens 6, arranged side by side with the screens 6; when there are four buttons 1, as shown... Figure 1 and Figure 2 As shown, the upper end of the connecting part 2 is connected to the two buttons 1 on the upper side, and the lower end of the connecting part 2 is connected to the two buttons 1 on the lower side. There are two screens 6, which are distributed left and right. Each screen 6 displays the button information of the two buttons 1. The connecting part 2 passes between the two screens 6 and is arranged side by side with the screens 6.

[0109] Existing smart switches with screens and buttons typically display the functions of the corresponding buttons on the screen. The screen display and button functions can only be changed via a mobile app, limiting the number of functions the switch can control. When the switch needs to control a large number of lights or multiple scene modes, the number of buttons may be insufficient. If the number of buttons is insufficient, a smart switch with more buttons can be used, but smart switches on the market are usually single, double, triple, or four-button, and more than four buttons can cause inconvenience in operation. If even a four-button smart switch is insufficient, a new smart switch needs to be added to achieve the desired result. Adding a new smart switch requires a series of procedures, including wall groove cutting, installation of junction boxes, cement drying, wall repair, and wiring, which are beyond the capabilities of ordinary users.

[0110] To solve the above problems, in the embodiments of the present invention, such as Figure 1As shown, the display cover 5 is provided with display areas 52 corresponding to the screen 6 one by one, and the display content of the screen 6 is displayed to the outside through the display areas 52; the screen 6 is electrically connected to the first circuit board 4, and the first circuit board 4 is provided with electronic switches 41 at the corresponding positions of each button 1, and the button 1 can be pressed to trigger the corresponding electronic switch 41; the first circuit board 4 is provided with a touch component 43, the touch component 43 is located within the coverage area of ​​the display cover 5, and the display cover 5 forms a touch area 51 at the corresponding position of the touch component 43.

[0111] In actual use, the function of button 1 can be switched in response to the touch area 51 being touched, so that one button 1 can control at least two functions, and the number of functions that the smart switch 100 can control can be expanded, so that the use needs can be met without adding new switches.

[0112] Furthermore, the functions controlled by each of the buttons 1 can be switched in response to a single touch operation of the touch component 43. That is, every time the user touches the touch area 51, the functions corresponding to all buttons 1 will be switched, thereby increasing the number of functions that the smart switch 100 can control by multiple times.

[0113] It is worth mentioning that placing the touch area 51 on the display cover 5 can prevent the touch area 51 from being touched when pressing the button 1.

[0114] The touch area 51 and the display area 52 are already present. Figure 1 The area is marked with a dashed box. The touch component 43 is capable of sensing touch operations on the touch area 51.

[0115] In some embodiments, the screen 6 is used to display the button information of the button 1. The screen 6 can switch the button information of the button 1 in response to the touch operation of the touch component 43, and the function controlled by the button 1 switches synchronously with the button information.

[0116] Furthermore, the default function of each button 1 is to control the on / off state of the corresponding relay. When the touch component 43 is touched, the function of each button 1 is switched to transmit wireless signals, and the smart switch 100 transmits wireless signals in response to the button 1 being pressed.

[0117] Furthermore, when the touch component 43 is touched, the function of each button 1 is switched from controlling the on / off state of the relay to controlling the scene mode.

[0118] In some embodiments, the number of touch areas 51 is one, and in other embodiments, the number of touch areas 51 is multiple.

[0119] In some embodiments, the touch area 51 is disposed on the left and right sides of the display area 52; in some embodiments, the touch area 51 is disposed between the display areas 52; in some embodiments, the touch area 51 is disposed on the lower side of the display area 52; and in some embodiments, the touch area 51 is disposed on the upper side of the display area 52.

[0120] In some embodiments, the number of screens 6 is multiple, and the number of display areas 52 is also multiple. The multiple display areas 52 are arranged along a first direction, and the touch area 51 is located between two adjacent display areas 52. For example... Figures 22-23 As shown, when there are two buttons 1, there are correspondingly two display areas 52. Both buttons 1 and display areas 52 are arranged along the first direction. The touch area 51 is located between the two display areas 52, and is positioned in the middle of the display cover 5. When there are three buttons 1 (not shown in the figure), there are correspondingly three display areas 52. Both buttons 1 and display areas 52 are arranged along the first direction. There are two touch areas 51, and each pair of the three display areas 52 is provided with a touch area 51. Figures 1-2 As shown, when there are four buttons 1, there are two display areas 52 and one touch area 51. The touch area 51 is located between the two display areas 52 and in the middle of the display cover 5.

[0121] In some embodiments, such as Figures 1-2 as well as Figures 22-23 As shown, there are multiple buttons 1, two screens 6, two display areas 52, and at least one touch area 51, which is located between the two display areas 52. The phrase "at least one touch area 51" can be understood as meaning that the number of touch areas 51 is one or more. When there is only one touch area 51, it is located between the two display areas 52; when there are multiple touch areas 51, all of them are located between the two display areas 52.

[0122] Furthermore, the first direction is horizontal, the two display areas 52 are arranged horizontally, and the horizontal width of the display cover 5 is greater than the vertical width.

[0123] Furthermore, such as Figures 1-2 As shown, there are four buttons 1, which are distributed at the four corners and in pairs on the upper and lower sides of the display cover 5; the two screens 6 display the button information of the four buttons 1 respectively.

[0124] Furthermore, such as Figures 1-2 As shown, the display cover 5 is horizontally disposed across the middle shell 3. There is one touch area 51, located in the center of the display cover 5. Two screens 6 are located on the left and right sides of the touch area 51, respectively. The left screen 6 corresponds to the two left buttons 1, and the right screen 6 corresponds to the two right buttons 1. The horizontal displacement can be understood as the left and right ends of the display cover 5 being flush with the left and right sides of the middle shell 3. The correspondence between the screens 6 and the buttons 1 can be understood as the left screen 6 and the two left buttons 1 being distributed in approximately a straight line vertically, and the right screen 6 and the two right buttons 1 being distributed in approximately a straight line vertically.

[0125] In other embodiments (not shown in the figures), there is one screen 6, one display area 52, and multiple buttons 1. The screen 6 displays button information for multiple buttons 1. There are multiple touch areas 51 located on both sides of the display area 52. In this embodiment, instead of multiple small screens 6, a single screen 6 is used, which is larger and displays button information for each button 1. The display area 52 is located in the middle of the display cover 5. Touch areas 51 are provided on both sides of the screen 6. The touch areas 51 can be located on the left and right sides or the top and bottom sides of the screen 6. The functions corresponding to the two touch areas 51 are set to control the left and right or the top and bottom pages of the displayed content. The screen 6 has multiple pages of button information preset. The two touch areas 51 are used to switch between pages of button information. At the same time, the function controlled by the button 1 switches synchronously with the button information. Based on this, the number of functions that the smart switch 100 can control is multiplied.

[0126] In some embodiments, such as Figure 1 and Figure 2 As shown, the touch area 51 is provided with an indicator pattern 511, and the first circuit board 4 is provided with a light-emitting element 44 at a position corresponding to the indicator pattern 511. The indicator pattern 511 is capable of transmitting light from the light-emitting element 44. The indicator pattern 511 is used to indicate the touch area 51. The indicator pattern 511 can be understood as a light-transmitting pattern, and the light-emitting element 44 is preferably an LED. Further, the light-emitting element 44 is positioned directly opposite the indicator pattern 511.

[0127] Furthermore, such as Figure 3As shown, a light-diffusing sheet 57 is provided on the back of the display cover 5 at the position corresponding to the indicator pattern 511. The light-diffusing sheet 57 is attached to the upper surface of the conductive foam 432. When the display cover 5 covers the middle shell 3, the light-diffusing sheet 57 is sandwiched between the conductive foam 432 and the display cover 5. The light emitted by the light-emitting element 44 is diffused by the light-diffusing sheet 57 and then passes through the indicator pattern 511. Further, the light-diffusing sheet 57 is made of white plastic sheet.

[0128] Furthermore, such as Figure 4 To display the back view of the cover plate 5, the back of the display cover plate 5 is covered with a first coating 551, which is a black opaque coating. The first coating 551 is hollowed out at the corresponding position of the indicator pattern 511 to form the indicator pattern 511. The area of ​​the touch area 51 except for the second coating 552 is covered by the first coating 551, so that the light from the light-emitting element 44 can only pass through the second coating 552.

[0129] The light-emitting element 44 can switch between a light-emitting state and a non-light-emitting state. Visible light with a wavelength of 550nm has a transmittance of greater than 5% and less than 35% through the indicator pattern 511. When the light-emitting element 44 is not emitting light, the indicator pattern 511 appears black, consistent with the color of other areas of the display cover 5, and is visually hidden. The indicator pattern 511 can only be seen by the user when the light-emitting element 44 is emitting light. When the user does not need the touch function, the touch function can be turned off, and the light-emitting element 44 can also be turned off; the indicator pattern 511 will not be displayed, and the display cover 5 will present a uniform black effect. In an exemplary embodiment, the transmittance of the indicator pattern 511 is 15% to better conceal the indicator pattern 511.

[0130] Furthermore, the back of the display cover 5 is covered with a second coating 552 on the indicator pattern 511. The second coating 552 is a black transparent coating, which enables the light transmittance of the indicator pattern 511 to reach the target value. The black transparent coating is similar to the coating on sunglasses; although black, it allows light to pass through.

[0131] Furthermore, the transmittance of visible light with a wavelength of 550nm through the display area 52 is greater than 5% and less than 35%. When the screen 6 is off, the display area 52 appears black to the outside, consistent with the color of other areas of the display cover 5. The display area 52 is visually hidden, and the display cover 5 presents a unified black effect.

[0132] In some embodiments, the brightness of the indicator pattern 511 that transmits light to the outside is set to L1, and the display brightness of the display area 52 is set to L2. This satisfies the relationship: |L1-L2|≤0.2*L2, thus ensuring that the brightness of the indicator pattern 511 that transmits light to the outside is approximately the same as the display brightness of the display area 52. During the design process, researchers use a brightness detector to measure the brightness of the indicator pattern 511 that transmits light to the outside, then adjust the brightness of the screen 6 based on the measurement results. They also use a brightness detector to measure the display brightness of the display area 52. After multiple adjustments to the screen 6 brightness, the final display brightness is made consistent with the brightness of the indicator pattern 511 that transmits light to the outside.

[0133] Furthermore, such as Figure 2 As shown, a distance detection module is provided within the area covered by the display cover 5. The light-emitting element 44 emits light in response to the triggering of the distance detection module. During use, when the user is far away from the smart switch 100, the distance detection module is not triggered, the light-emitting element 44 does not emit light, and the indicator pattern 511 is displayed as black. The indicator pattern 511 visually blends into the display cover 5, achieving a one-piece black effect for the display cover 5. When the user is near the front of the smart switch 100, the distance detection module is triggered, the light-emitting element 44 is lit, and the light from the light-emitting element 44 shines through the indicator pattern 511, making the indicator pattern 511 visible to the user for touch control.

[0134] Furthermore, the distance detection module includes an infrared emitting unit 451 and an infrared receiving unit 452. The infrared emitting unit 451 is used to emit infrared light, which passes through the display cover 5 and is emitted outward. The infrared light is reflected by external objects and partially returns to the infrared receiving unit 452. When the infrared light received by the infrared receiving unit 452 is greater than a threshold, the distance detection module is triggered.

[0135] Furthermore, the infrared light emission range is a cone-shaped area directly in front of the smart switch 100. When there is a nearby object directly in front of the smart switch 100, the intensity of the infrared light reflected by the object increases, and the infrared light received by the infrared receiving unit 452 increases accordingly.

[0136] Furthermore, the infrared emitting unit 451 adopts an infrared light-emitting tube, and the infrared receiving unit 452 adopts an infrared receiving head.

[0137] Furthermore, such as Figure 2 and Figure 7 As shown, the middle shell 3 has an infrared emitting hole 341 at the position corresponding to the infrared emitting unit 451, and an infrared receiving hole 342 at the position corresponding to the infrared receiving unit 452. Both the infrared emitting hole 341 and the infrared receiving hole 342 are located within the area covered by the display cover plate 5.

[0138] Furthermore, such as Figure 4 As shown, the first coating 551 has hollowed out corresponding positions on the infrared emitting unit 451 and the infrared receiving unit 452 to form an infrared emitting area 53 and an infrared receiving area 54, respectively. The transmittance of visible light with a wavelength of 550nm through the infrared emitting area 53 and the infrared receiving area 54 is greater than 5% and less than 35%. Therefore, the infrared emitting area 53 and the infrared receiving area 54 appear black to the outside, consistent with the color of other areas of the display cover 5. The infrared emitting area 53 and the infrared receiving area 54 are visually hidden, and the display cover 5 presents a unified black effect.

[0139] Furthermore, the transmittance of infrared light with a wavelength of 940nm through both the infrared emitting area 53 and the infrared receiving area 54 is greater than 70% and less than 95%, to ensure the accuracy of the distance detection module. Furthermore, the back of the display cover 5 is covered with a third coating 553 on the infrared emitting area 53 and the infrared receiving area 54. The third coating 553 is a black transparent coating, ensuring that the transmittance of the infrared emitting area 53 and the infrared receiving area 54 reaches the target value.

[0140] Furthermore, such as Figure 4 As shown, the first coating 551 is hollowed out at the corresponding position of the display area 52 to form the display area 52; the back of the display cover 5 is covered with a fourth coating 554 on the display area 52. The fourth coating 554 is a black transparent coating, so that the transmittance of visible light with a wavelength of 550nm through the infrared emitting area 53 and the infrared receiving area 54 is greater than 5% and less than 35%. Therefore, when the screen 6 is not lit, the display area 52 appears black, consistent with the color of other areas of the display cover 5, and the display area 52 is visually hidden, giving the display cover 5 a unified black effect.

[0141] Furthermore, the second coating 552, the third coating 553, and the fourth coating 554 are the same coating. During production, this coating is first applied to the back of the display cover plate 5, and then the first coating 551 is applied on top of this coating.

[0142] Furthermore, such as Figure 15As shown, a first enclosure space 391 is provided on the back of the middle shell 3 at the position corresponding to the infrared emitting hole 341. The infrared emitting unit 451 is placed inside the first enclosure space 391. A first enclosure wall is provided around the first enclosure space 391, surrounding the infrared emitting unit 451. A second enclosure space 392 is provided on the back of the middle shell 3 at the position corresponding to the infrared receiving hole 342. The infrared receiving unit 452 is placed inside the second enclosure space 392. A second enclosure wall is provided around the second enclosure space 392, surrounding the infrared receiving unit 452. This prevents the infrared light emitted by the infrared emitting unit 451 from propagating from inside the smart switch 100 to the infrared receiving unit 452, thereby avoiding the infrared receiving unit 452 from being falsely triggered. The first and second enclosure walls extend from the back of the middle shell 3. Furthermore, the first and second enclosure walls respectively abut against the first circuit board 4 to prevent infrared light from passing through the gap between the first and second enclosure walls and the first circuit board 4.

[0143] Furthermore, such as Figure 15 As shown, a plurality of baffles 393 are provided on the back of the middle shell 3 between the first enclosure space 391 and the second enclosure space 392. The baffles 393 extend on the back of the middle shell 3 and can further block the infrared light emitted by the infrared emitting unit 451 from propagating from the inside of the smart switch 100 to the infrared receiving unit 452, thereby preventing the infrared receiving unit 452 from being accidentally triggered.

[0144] In some embodiments, such as Figure 5 As shown, the first circuit board 4 is disposed on the side of the middle shell 3 opposite to the display cover plate 5, as... Figure 7 As shown, the middle shell 3 has a second touch hole 343 at the corresponding position of the touch area 51; as Figure 3 and Figure 13 As shown, the touch component 43 includes a sensing sheet 431 located on the first circuit board 4 and a conductive foam 432 located in the second touch hole 343. The conductive foam 432 abuts against the sensing sheet 431 and is sandwiched between the sensing sheet 431 and the display cover plate 5. The display cover plate 5 forms a touch area 51 at the corresponding position of the touch component 43.

[0145] exist Figure 13 In the diagram, the left side is a top view of the first circuit board 4, and the right side is a bottom view of the first circuit board 4.

[0146] Among them, such as Figure 13As shown, the sensing sheet 431 is a thin metal sheet laid on the first circuit board 4 and electrically connected to the sensing chip. The conductive foam 432 is constructed as an elastic foam with conductive properties to extend the sensing height. The bottom of the conductive foam 432 abuts against the sensing sheet 431, and the top is directly or indirectly abutted by the display cover plate 5. The sensing sheet 431 and the conductive foam 432 serve as sensing electrodes, forming an electrostatic field. The sensing principle of the touch component 43 is capacitive touch sensing. The human body, as a conductor, changes the capacitance between the electrode and ground when touched. When the user's finger clicks the touch area 51, the finger and the conductive foam 432 form a coupling capacitance, changing the original capacitance value. The sensing chip detects the capacitance change and outputs relevant commands. Furthermore, the sensing chip is a microcontroller, and the sensing chip is soldered to the back of the first circuit board.

[0147] Furthermore, the sensing sheet 431 is square-shaped, and the light-emitting element 44 is located at the center of the square-shaped sensing sheet 431.

[0148] Furthermore, the light-diffusing sheet 57 is disposed between the conductive foam 432 and the display cover plate 5, and the display cover plate 5 is indirectly abutted against the top of the conductive foam 432 through the light-diffusing sheet 57.

[0149] like Figure 2 and Figure 5 As shown, the conductive foam 432 has a light guide hole 4321, which corresponds to the position of the light-emitting element 44. The light emitted by the light-emitting element 44 passes through the light guide hole 4321 and illuminates the indicator pattern 511, and then shines through the indicator pattern 511. Furthermore, the area of ​​the light guide hole 4321 in the horizontal direction can cover the area of ​​the indicator pattern 511.

[0150] like Figure 6 As shown, the connecting part 2 has a first touch hole 23, which is directly opposite to the second touch hole 343. The first touch hole 23 in the connecting part 2 integrates the touch component 43 and the connecting part 2 in the same position.

[0151] Furthermore, both the first touch hole 23 and the second touch hole 343 are square through holes, and the conductive foam 432 is a cuboid.

[0152] Furthermore, such as Figure 3 As shown, adhesive is provided on the back of the display cover 5, which is then attached to the middle shell 3 and the connecting part 2, thereby fixing the connecting part 2. Fixing the connecting part 2 prevents the button 1 from wobbling in the horizontal direction, and the positional relationship between the button 1 and the middle shell 3 is fixed. Using the display cover 5 to fix the connecting part 2 eliminates the need for an additional fixing structure, resulting in a simpler structure, reduced panel thickness, and improved assembly efficiency.

[0153] Furthermore, such as Figure 3 and Figure 2 As shown, the middle shell 3 includes a first surface for attaching the display cover plate 5, and the connecting part 2 includes a second surface that is flush with the first surface. The second surface and the first surface are used together to attach the display cover plate 5.

[0154] Furthermore, such as Figure 3 As shown, the adhesive on the back of the display cover 5 is set as double-sided adhesive 56, and the double-sided adhesive 56 has a hollowed-out area in the touch area 51, the display area 52, the infrared emitting area 53 and the infrared receiving area 54.

[0155] Furthermore, such as Figure 2 As shown, the middle shell 3 is provided with a positioning part 35, and the connecting part 2 is positioned and engaged with the positioning part 35 to ensure accurate positional relationship between the button 1 and the middle shell 3. The positioning part 35 can be a positioning post, a positioning groove, or other structure with positioning function. In an exemplary embodiment, as shown... Figures 6-8 As shown, the positioning part 35 includes positioning walls 351 abutting against both sides of the connecting part 2, and positioning ribs 352 located at the four corners of the connecting part 2. Positioning grooves 21 are respectively provided at the four corners of the connecting part 2, and the positioning ribs 352 are embedded in the positioning grooves 21. Further, the positioning part 35 also includes a square positioning frame 353 arranged around the second touch hole 343. The square positioning frame 353 protrudes from the middle shell 3. A square positioning groove 22 is provided around the first touch hole 23 of the connecting part 2, and the square positioning frame 353 is embedded in the square positioning groove 22.

[0156] In some embodiments, such as Figure 7 As shown, the middle shell 3 is provided with a mounting groove 36, and the screen 6 is mounted in the mounting groove 36 through the opening side of the mounting groove 36. The opening side of the mounting groove 36 is closed by the display cover plate 5. Figure 14 As shown, the ribbon cable 61 of the screen 6 passes through the middle shell 3 and connects to the ribbon cable 61 connector 46 of the first circuit board 4. The ribbon cable 61 connector 46 is disposed on the lower surface of the first circuit board 4. Figure 14 This is a rear view of the middle shell 3 and the first circuit board 4.

[0157] Furthermore, the mounting groove 36 is a square groove, and each side wall of the mounting groove 36 is provided with a positioning protrusion. The positioning protrusion abuts against the side of the screen 6 so that the relative position of the screen 6 in the mounting groove 36 is accurate.

[0158] Furthermore, the back of the screen 6 is glued to the mounting slot 36 to facilitate the installation of the display cover 5.

[0159] exist Figures 22-23 In the illustrated embodiment, since the screen 6 and touch component 43 are located at the top of the panel, while the first circuit board 4 is located in the middle of the middle shell 3, it is difficult to directly mount the touch component 43 and the light-emitting element 44 onto the first circuit board 4. In this embodiment, the smart switch 100 also includes a third circuit board 83. The sensing sheet 431 of the light-emitting element 44 and the touch component 43 are both mounted on the third circuit board 83. The third circuit board 83 is a small circuit board, and the second touch hole 343 is replaced with a second touch slot. The third circuit board 83 and conductive foam 432 are mounted in the second touch slot. A second ribbon cable is pasted or soldered onto the third circuit board 83. The second ribbon cable passes through the second touch slot and connects to the back of the first circuit board 4. The third circuit board 83 and conductive foam 432 are confined between the display cover 5 and the middle shell 3. Furthermore, since the third circuit board 83 and the touch component 43 occupy the thickness of the middle shell 3, compared to... Figures 1-21 In the embodiment shown, the middle shell 3 is thicker and the conductive foam 432 is thinner.

[0160] exist Figures 22-23 In the illustrated embodiment, there are two buttons 1, two corresponding electronic switches 41, and two display areas 52. Both buttons 1 and display areas 52 are arranged along a first direction. The touch area 51 is located between the two display areas 52, and is positioned in the middle of the display cover plate 5. Other technical details of this embodiment can be found in... Figures 1-21 The implementation examples have been adapted and will not be described in detail here.

[0161] Existing smart switches typically have a low-voltage circuit board and a high-voltage circuit board. The low-voltage circuit board is located in the middle shell, and a cover plate is installed at the bottom of the middle shell to cover the low-voltage circuit board. The high-voltage circuit board is located in a receiving groove in the bottom shell. Generally, the low-voltage circuit board and the cover plate cannot utilize the thickness of the bottom shell, which means that the low-voltage circuit board and the cover plate must occupy the thickness of the middle shell, resulting in a relatively thick middle shell.

[0162] To solve the above problems, in the embodiments of the present invention, such as Figures 14-17 As shown, the smart switch 100 also includes a bottom shell 7, which has a second receiving groove 71; a middle shell 3 is detachably connected to the bottom shell 7 and covers the opening side of the second receiving groove 71; wherein, the middle shell 3 has a first receiving groove 37 facing the bottom shell 7, the first receiving groove 37 is embedded in the second receiving groove 71, the first receiving groove 37 contains a first circuit board 4, and the first circuit board 4 can be detached from the bottom shell 7 along with the middle shell 3; the second receiving groove 71 contains a second circuit board 72, and the second circuit board 72 is electrically connected to the first circuit board 4.

[0163] In this embodiment of the invention, the first circuit board 4 is installed inside the first receiving groove 37, and the first receiving groove 37 is embedded in the second receiving groove 71 of the bottom shell 7. Thus, the first circuit board 4 borrows space from the bottom shell 7 in terms of thickness. When the bottom of the first receiving groove 37 is provided with a first cover plate 81, the first cover plate 81 is also placed in the second receiving groove 71. The first cover plate 81 and the first circuit board 4 do not occupy the thickness of the middle shell 3, and the panel of the smart switch 100 can be thinned, so that the smart switch 100 can achieve an ultra-thin panel design.

[0164] in, Figure 14 and Figure 15 These are all views from the back of the middle shell 3, such as Figure 15 As shown, the first receiving groove 37 can be a groove structure formed by the mutual enclosure of each side wall, or it can be a groove structure in which the side walls are not completely enclosed.

[0165] Furthermore, the first circuit board 4 is a low-voltage circuit board used to carry low-voltage circuits, and the second circuit board 72 is a high-voltage circuit board used to carry high-voltage circuits. The second circuit board 72 is equipped with a power module and a relay. The power module is connected to 220V AC power and converts the AC power into low-voltage DC power to provide power to the low-voltage circuits. The relay is connected to the controlled lighting fixtures to control the on / off state of the lighting fixtures.

[0166] Furthermore, such as Figure 17 and Figures 7-8 As shown, the button 1 is located on the side of the middle shell 3 facing away from the bottom shell 7. A first recess 38 is provided on the side of the middle shell 3 facing the button 1. The first recess 38 is located within the corresponding area of ​​the first receiving groove 37. When the button 1 is pressed, a portion of the button 1 sinks into the first recess 38. Thus, the first groove utilizes the space of the bottom shell 7 to provide downward pressure space for the button 1, which helps to reduce the panel thickness. The corresponding area of ​​the first receiving groove 37 can be understood as the area directly above the first receiving groove 37. The first recess 38 being located within the corresponding area of ​​the first receiving groove 37 can be understood as the projected shape formed by the first receiving groove 37 projecting onto the middle shell 3 covering the first recess 38.

[0167] Furthermore, such as Figures 7-8 As shown, the button support 13 of button 1 has an edge rib 133 near the edge. The first recess 38 includes an edge recess located at the edge of the first recess 38. The shape of the edge recess is adapted to the edge rib 133. When button 1 is pressed, the edge rib 133 sinks into the edge recess.

[0168] Furthermore, such as Figures 7-8As shown, the button 1 is provided with a latching part 132 for latching the middle shell 3. The latching part 132 is located within the corresponding range of the first recess 38, that is, the latching part 132 is located in the area directly above the first receiving groove 37 of the bottom shell 7. The latching part 132 can use the space of the first receiving groove 37, so that the latching part 132 does not occupy the thickness of the middle shell 3, which is conducive to realizing the ultra-thin panel design.

[0169] The snap-fit ​​part 132 snaps into the snap-fit ​​position 33 of the middle shell 3, and the snap-fit ​​position 33 is located in the area of ​​the first groove. The technical details of the snap-fit ​​part 132 and the snap-fit ​​position 33 have been described in detail above, and will not be repeated here.

[0170] Furthermore, such as Figures 7-8 As shown, the first circuit board 4 is provided with an electronic switch 41 at the corresponding position of each button 1. Each button 1 is provided with a trigger part 131 for triggering the electronic switch 41. The trigger part 131 is located within the corresponding range of the first recess 38, which is beneficial for realizing an ultra-thin panel design.

[0171] In some embodiments, such as Figure 7 and Figure 21 As shown, a second recess 381 is provided on the side of the middle shell 3 facing the button 1, and the second recess 381 is located around the first recess 38. The function of the second recess 381 is as follows: Figure 21 As shown, when button 1 is composed of a button bracket 13 made of plastic material and a button 1 cover made of glass material, in order to make the button bracket 13 and the button 1 cover bond stably, the area of ​​the button bracket 13 will increase, causing the button bracket 13 to exceed the range of the first recess 38. Therefore, in this embodiment, a second recess 381 is provided around the first recess 38, and the second recess 381 provides a downward pressure space for the button bracket 13.

[0172] Furthermore, such as Figures 20-21 As shown, the button 1 consists of a button bracket 13 and a button plate 14. The button plate 14 is glued and fixed to the upper surface of the button bracket 13. When the button 1 is pressed, the button bracket 13 sinks into the second recess 381.

[0173] Furthermore, such as Figure 20As shown, the button bracket 13 has an annular glue groove 135 on the side facing the button plate 14. The annular glue groove 135 is used for applying glue so that the button plate 14 is attached to the button bracket 13. The annular glue groove 135 is recessed at the center of the connecting part 2 to form a recessed section 1351, thereby leaving a deformation space between the recessed section 1351 and the connecting part 2. When the button 1 is pressed, the connecting part 2 connected to the button 1 and the part near the connecting part 2 will undergo a large deformation. The recessed section 1351 can avoid the part with large deformation and prevent the button plate 14 from delaminating with the button bracket 13.

[0174] In some embodiments, such as Figure 15 As shown, where Figure 15 From the rear view of the middle shell 3, the middle shell 3 is provided with a plurality of surrounding walls 371 protruding toward the bottom shell 7. The surrounding walls 371 surround each other to form the first receiving groove 37 inside the surrounding walls 371, and the surrounding walls 371 are received in the second receiving groove 71.

[0175] Furthermore, such as Figure 16 As shown, a first cover plate 81 is provided at the bottom of the first receiving groove 37, the first circuit board 4 is disposed in the space between the first cover plate 81 and the first receiving groove 37, and the second circuit board 72 is disposed outside the space between the first cover plate 81 and the first receiving groove 37. When the middle shell 3 is removed from the bottom shell 7, the first circuit board 4 and the first cover plate 81 are removed from the bottom shell 7 together with the middle shell 3.

[0176] The bottom shell 7 has mounting holes 74 on both sides. When installing the smart switch 100, the middle shell 3 must first be removed from the bottom shell 7 to expose the mounting holes 74. The mounting holes 74 are connected to a wall-mounted junction box via connecting screws, thereby fixing the bottom shell 7 to the wall. The mounting holes 74 are countersunk holes, and the nuts of the connecting screws are accommodated in the mounting holes 74.

[0177] The surrounding wall 371 is a vertical wall. The surrounding wall 371 can completely surround the side of the second receiving groove 71, or it can only surround a portion of the side, leaving the other portion open. In an exemplary embodiment, as... Figure 15 and Figure 14 As shown, the surrounding wall 371 is broken in the corresponding area of ​​the two mounting holes 74, so that the two sides of the first circuit board 4 are not blocked by the surrounding wall 371. The user can pinch the two sides of the first circuit board 4 to assemble the first circuit board 4 into the middle shell 3, making the assembly more convenient.

[0178] Furthermore, such as Figure 16 and Figure 12As shown, U-shaped walls 811 extend from both sides of the first cover plate 81 toward the middle shell 3. The cross-section of the U-shaped wall 811 is a concave U-shape. The position of the U-shaped wall 811 corresponds to the break area of ​​the surrounding wall 371. The U-shaped wall 811 is used to close the break area of ​​the surrounding wall 371, so that the first circuit board 4 is closed between the first receiving groove 37 and the first cover plate 81.

[0179] Furthermore, such as Figure 16 As shown, the two sides of the surrounding wall 371 are respectively snapped into the first end cap.

[0180] Furthermore, such as Figures 16-18 As shown, a second cover plate 82 is disposed within the second receiving groove 71, dividing the second receiving groove 71 into an upper space and a lower space. The first receiving groove 37 is located in the upper space, and the second circuit board 72 is located in the lower space. The first circuit board 4 and the second circuit board 72 are electrically connected through a pin header 47 and a female header 721. The first cover plate 81 has a first through hole 813 at the corresponding position of the pin header 47, and the second cover plate 82 has a second through hole 822 at the corresponding position of the first through hole 813. One of the pin header 47 and the female header 721 is disposed on the first circuit board 4, and the other is disposed on the second circuit board 72. In an exemplary embodiment, the pin header 47 is disposed on the lower surface of the first circuit board 4, and the female header 721 is disposed on the upper surface of the second circuit board 72. The pin header 47 is exposed through the first through hole 813, and the female header 721 is exposed through the second through hole 822.

[0181] Furthermore, such as Figure 18 As shown, the two ends of the second cover plate 82 are respectively snapped into the inner wall of the second receiving groove 71. The second circuit board 72 is clamped and fixed by the second end cover and the bottom shell 7.

[0182] Furthermore, such as Figure 16 and Figure 17 As shown, a wireless communication module 48 is provided on the lower surface of the first circuit board 4, the upper surface of the first cover plate 81 is recessed downward at the position corresponding to the wireless communication module 48, the lower surface of the first cover plate 81 protrudes downward at the position corresponding to the wireless communication module 48 to form a protrusion 812, and the second cover plate 82 is recessed downward at the position corresponding to the protrusion 812 to form a recess 821.

[0183] Furthermore, such as Figures 17-19As shown, the lower end of the second circuit board 72 is provided with multiple wiring terminals, including wiring screws 722. An operating hole 73 is formed on the side of the bottom shell 7, directly opposite the wiring screws 722. A user can use a screwdriver to operate the wiring screws 722 through the operating hole 73. The wiring screws 722 are confined inside the operating hole 73 and cannot be disengaged. A distance-increasing ring 731 protrudes outward from the outer edge of the operating hole 73. The distance-increasing ring 731 increases the distance between the wiring screws 722 and the outside, preventing the user's fingers from touching the wiring screws 722 and causing electric shock.

[0184] In some embodiments, such as Figure 14 As shown, the first circuit board 4 is directly fixedly connected to the middle shell 3; wherein, the first circuit board 4 is fixedly connected to the middle shell 3 by circuit board screws 491, or the first circuit board 4 is snap-fitted to the middle shell 3. Because the first circuit board 4 is directly fixed to the middle shell 3, the positional relationship between the first circuit board 4 and the middle shell 3 is stable, thereby providing stable support for the electronic switch 41 by the first circuit board 4, ensuring that the button 1 can stably trigger the electronic switch 41 within a short stroke, laying the foundation for achieving an ultra-thin panel.

[0185] In an exemplary embodiment, such as Figures 13-15 As shown, the first circuit board 4 is provided with four connection holes 49. The back of the middle shell 3 is provided with a connecting post 344 at the corresponding position of each connection hole 49. A connecting seat is provided at the root of the connecting post 344. The connecting post 344 is inserted into the connection hole 49 to position the circuit board in the horizontal direction. The circuit board abuts against the connecting seat to make the circuit board accurately positioned in the vertical direction. Each connecting post 344 is screwed into a circuit board screw 491, and the circuit board screw 491 fixes the first circuit board 4 to the middle shell 3.

[0186] 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.
