Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch technology, and in particular 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 some structural features in their panel components that could be improved. Utility Model Content
[0004] Existing smart switches integrate many components into their panel assemblies, such as the inner shell, control circuit board, electronic switch, and buttons. Because these components are stacked vertically, the panel assembly is quite thick. When the switch is installed on the wall, the panel assembly protrudes significantly from the wall, affecting the user experience.
[0005] One objective of this invention is to provide an intelligent switch in which a first circuit board and electronic components are indirectly housed in the bottom shell through a first recessed space and a second recessed space, thereby reducing the thickness of the panel assembly located on the outside of the wall occupied by the first circuit board, making the panel assembly protruding from the wall thinner, and achieving an ultra-thin user experience.
[0006] Another objective of this invention is to provide an intelligent switch in which the second recessed space is used to accommodate the electronic components of the first circuit board, so that the first recessed space does not need to accommodate the electronic components, and the depth of the first recessed space can be designed to be thinner, thereby the depth of the accommodating space of the bottom shell can also be designed to be thinner, so that in the horizontal direction, the first accommodating space is not constrained by the internal structure of the dark box, and the area of the first accommodating space can be further increased, thereby increasing the area of the first recessed space. The first circuit board can be completely sunk into the first recessed space while ensuring that the area is large enough, thus reducing the thickness of the panel assembly protruding from the wall.
[0007] Another objective of this invention is to provide an intelligent switch, wherein the increased area of the first circuit board allows for the placement of more electronic components on the first circuit board, and the electronic switch can be placed at a more peripheral position on the panel assembly, which is beneficial for the buttons and screen to be arranged side by side.
[0008] Another objective of this invention is to provide an intelligent switch in which the first accommodating space and the second accommodating space are stacked vertically to increase the area of the first accommodating space, so that the first circuit board can be completely submerged in the first recessed space while ensuring that the area is large enough.
[0009] Another objective of this utility model is to provide an intelligent switch, wherein the first accommodating space is located above the connecting ear of the dark box, and the bottom shell uses the space above the connecting ear of the dark box to construct the first accommodating space. The first accommodating space is used to create the sinking conditions for the first sinking part. The first sinking part reserves a downward recessed depth for the first sinking space, so that the first sinking space has enough depth to accommodate the first circuit board, making the thickness of the panel assembly protruding from the wall thinner.
[0010] Another objective of this invention is to provide an intelligent switch in which the first circuit board is indirectly sunk into the interior of the bottom shell through a first sunken space, further reducing the thickness of the panel assembly protruding from the wall.
[0011] Another objective of this invention is to provide an intelligent switch in which the electronic switch is housed in a first recessed space, further reducing the thickness of the panel assembly protruding from the wall.
[0012] Another objective of this invention is to provide an intelligent switch in which the area of the first recessed space in the horizontal direction is increased, resulting in a larger area of the first circuit board and allowing the electronic switch to be positioned closer to the edge.
[0013] Another objective of this invention is to provide an intelligent switch in which the side length of the first projected pattern is greater than 60mm and less than 68mm, thereby maximizing the lateral area of the first accommodating space within the accommodating range of the 86-cell dark box.
[0014] Another objective of this invention is to provide an intelligent switch in which the depth of the first receiving space is less than 5mm, so as to avoid interference between the bottom wall of the first receiving space and the connecting ear during installation of the bottom shell.
[0015] Another objective of this invention is to provide an intelligent switch in which the nut of the threaded connector is accommodated in a first accommodating space, thereby increasing the area of the first accommodating space.
[0016] Another objective of this invention is to provide an intelligent switch in which the nut is small in size and the nut boss occupies a small space, so that the first recessed space is less affected by the nut boss.
[0017] Another objective of this invention is to provide an intelligent switch in which the distance between the electronic switch in the middle and the nut boss is less than 2mm, so that the distance between the electronic switch and the button shaft meets the requirements and avoids the electronic switch from being unable to be triggered due to insufficient pressing stroke of the button.
[0018] Another objective of this invention is to provide a smart switch in which a portion of the wireless communication module is housed in a third recessed space to further reduce the thickness of the panel assembly protruding from the wall.
[0019] Another objective of this utility model is to provide an intelligent switch in which the partition plate is integrally formed in the middle shell, that is, the middle shell does not provide a partition plate between the first circuit board and the screen, so that the gap between the first circuit board and the screen can accommodate more electronic components. Based on this, the electronic components set on the upper surface of the first circuit board can be completely sunk into the first sunken space, which greatly reduces the thickness of the panel assembly protruding from the wall.
[0020] Another objective of this invention is to provide an intelligent switch in which the pivot is located at the end of the button closer to the screen, so that the pressing motion of the button is more adapted to the user's usage habits.
[0021] Another objective of this invention is to provide an intelligent switch in which L2 satisfies the relationship: L2≤L1*3 / 4. By shortening the distance between the hook and the rotating shaft, the travel of the hook is reduced during the pressing process, so that the hook will not touch the top plate of the bottom shell within the travel range, ensuring that the button can trigger the electronic switch within the pressing range.
[0022] Another objective of this invention is to provide an intelligent switch in which the distance between the trigger pins at both ends and the rotating shaft is greater than the distance between the trigger pin at the middle position and the rotating shaft, so that the travel of the trigger pins at both ends is longer, thereby ensuring that the electronic switch can be successfully triggered when the corners of the buttons at both ends are pressed.
[0023] Another objective of this invention is to provide an intelligent switch in which the button relies on the spring force of the electronic switch to reset, eliminating the need for an additional reset structure. This not only simplifies the structure of the panel assembly but also reduces the force required to press, improving the tactile feel. Furthermore, since the button is always in contact with the electronic switch, the button's trigger stroke is shorter, the trigger is more sensitive, and the trigger force feedback is clearer.

[0066] 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.

[0067] Existing smart switches integrate many components into their panel assemblies, such as the inner shell, control circuit board, electronic switch, and buttons. Because these components are stacked vertically, the panel assembly is quite thick. When the switch is installed on the wall, the panel assembly protrudes significantly from the wall, affecting the user experience.
[0068] To solve the above problems, this utility model provides an intelligent switch 100. Please refer to [link / reference]. Figures 1-24 The intelligent switch 100 provided by this utility model will be explained in detail. Specifically, as... Figures 1-8 As shown, the smart switch 100 includes a bottom shell 7 and a panel assembly 110. The panel assembly 110 includes a first circuit board 2 and a partition plate 11 for separating the first circuit board 2 from the bottom shell 7. The partition plate 11 has a first side facing the bottom shell 7 and a second side away from the bottom shell 7. The first side has a first recessed portion 111 protruding from the bottom shell 7, and the first recessed portion 111 has a second recessed portion 112 protruding from the bottom shell 7. The bottom shell 7 is provided with a first receiving space 71 and a second receiving space 72. The first receiving space 71 receives the first recessed portion 111, and the second receiving space 72 receives the second recessed portion 112. The second side is recessed at a position corresponding to the first recessed portion 111 to form a first recessed space 113, and the first recessed space 113 is recessed at a position corresponding to the second recessed portion 112 to form a second recessed space 114. The first circuit board 2 is placed in the first recessed space 113, and at least part of the electronic components of the first circuit board 2 are received in the second recessed space 114.
[0069] The smart switch 100 provided by this utility model has a first circuit board 2 and electronic components indirectly housed in the bottom shell 7 through a first recessed space 113 and a second recessed space 114. This reduces the thickness of the panel assembly 110 located on the outside of the wall occupied by the first circuit board 2, making the panel assembly 110 protrude thinner from the wall and achieving an ultra-thin user experience.
[0070] It is important to note that, such as Figure 5 and Figure 6As shown, since the first sunken space 113 sinks down again to form the second sunken space 114, the second sunken space 114 is used to accommodate the electronic components of the first circuit board 2. This means that the first sunken space 113 does not need to accommodate electronic components, and the depth of the first sunken space 113 can be designed to be thinner. Consequently, the depth of the accommodating space of the bottom shell 7 can also be designed to be thinner. This means that in the horizontal direction, the first accommodating space 71 is not constrained by the internal structure of the dark box 200, and the area of the first accommodating space 71 can be further increased. As a result, the area of the first sunken space 113 can also be increased. The first circuit board 2 can be completely sunk into the first sunken space 113 while ensuring that the area is large enough, thus reducing the thickness of the panel assembly 110 protruding from the wall. The advantage of increasing the area of the first circuit board 2 is that it is easier to arrange more electronic components on the first circuit board 2, and the electronic switch 21 can be arranged at a more peripheral position on the panel assembly 110, which is beneficial for the button 31 and the screen 4 to be arranged side by side.
[0071] The panel assembly 110 includes a middle shell 1. The partition plate 11 may be integrally formed with the middle shell 1 or independently fixedly connected to the middle shell 1. In an exemplary embodiment, the partition plate 11 is integrally formed with the middle shell 1. The first surface of the partition plate 11 can be understood as... Figure 6 The lower surface of the middle partition 11, the second surface can be understood as Figure 6 The upper surface of the partition plate 11. The function of the first recessed portion 111 is to reserve a thickness for the downward concavity of the first recessed space 113, and the function of the second recessed portion 112 is to reserve a thickness for the downward concavity of the second recessed space 114. The thickness of the partition plate 11, the wall thickness of the first recessed portion 111, and the wall thickness of the second recessed portion 112 tend to be consistent.
[0072] The first recessed portion 111 is embedded in the first receiving space 71, and the gap between the side wall of the first receiving space 71 and the first recessed portion 111 is less than 2mm; the second recessed portion 112 is embedded in the second receiving space 72, and the gap between the side wall of the second receiving space 72 and the second recessed portion 112 is less than 2mm.
[0073] The fact that the electronic components of the first circuit board 2 are at least partially housed in the second recessed space 114 can be understood as the electronic components being fully or partially housed in the second recessed space 114. In one exemplary embodiment, the lower surface of the first circuit board 2 is attached to the bottom of the first recessed space 113, and the electronic components on the lower surface of the first circuit board 2 are fully housed in the second recessed space 114; in another exemplary embodiment, such as Figure 6 and Figure 8As shown, the bottom of the first sunken space 113 and the second sunken space 114 are provided with multiple supporting ribs 115 to support the first circuit board 2, so that the first circuit board 2 is suspended in the first sunken space 113, and only a portion of the electronic components located on the lower surface of the first circuit board 2 are accommodated in the second sunken space 114.
[0074] In contrast to the first sunken space 113 directly supporting the first circuit board 2, this embodiment uses multiple supporting ribs 115 to support the first circuit board 2 at multiple points, which can improve the positional accuracy of the first circuit board 2. Figure 8 and Figure 11 As shown, the support ribs 115 are respectively provided at the corresponding positions of the electronic switch 21 and the ribbon cable connection terminal 22 on the first circuit board 2. The ribbon cable connection terminal 22 is used to connect the ribbon cable of the screen 4.
[0075] It is worth noting that, in Figure 5 and Figure 6 In the first circuit board 2, only the wireless communication module 23 is shown; no other electronic components are shown.
[0076] Furthermore, such as Figure 7 As shown, along the direction from the panel assembly 110 to the bottom shell 7, the first accommodating space 71 and the second accommodating space 72 are arranged sequentially; that is, the first accommodating space 71 and the second accommodating space 72 are stacked vertically to increase the horizontal area of the first accommodating space 71, so that the first circuit board 2 can be completely submerged in the first recessed space 113 while ensuring a sufficiently large area. Figure 10 As shown, the bottom shell 7 is installed in the junction box 200 on the wall 300. The inner wall of the junction box 200 is provided with two connecting ears 210 for connecting the bottom shell 7. The first accommodating space 71 is located on the side of the connecting ears 210 facing the panel assembly 110, that is, the first accommodating space 71 is located above the connecting ears 210. The bottom shell 7 uses the space above the connecting ears 210 in the junction box 200 to construct the first accommodating space 71. The first accommodating space 71 creates the sinking conditions for the first sinking part 111. The first sinking part 111 reserves a depth for the first sinking space 113 to be recessed downward, so that the first sinking space 113 has enough depth to accommodate the first circuit board 2, making the thickness of the panel assembly 110 protruding from the wall thinner.
[0077] In addition, the bottom shell 7 uses the space above the connecting ear 210 to construct the first receiving space 71, so that the area of the first receiving space 71 in the horizontal direction is not constrained by the connecting ear 210, the area of the first receiving space 71 can be increased, thereby increasing the area of the first sinking space 113 in the horizontal direction, and finally enabling the first circuit board 2 to be completely sunk into the first sinking space 113 while increasing its area.
[0078] The junction box 200 can be understood as a switch mounting box embedded in the wall. The function of the junction box 200 is to install the wall switch and store wires. Common junction boxes 200 include the 86-type and 118-type. One end of the junction box 200 is open, and the connecting ears 210 protrude from the inner walls on both sides. The connecting ears 210 have threaded holes, and the bottom shell 7 of the wall switch is connected to the threaded holes by screws, thereby fixing the wall switch to the wall surface 300. The smart switch 100 provided by this utility model utilizes the distance between the connecting ears 210 and the open end of the junction box 200 to construct the first receiving space 71, creating conditions for the first circuit board 2 to sink into the first recessed space 113. After the junction box 200 is embedded in the wall, the wall surface 300 is plastered. Finally, the open end of the junction box 200 will be flush with or slightly lower than the wall surface 300. That is, the distance between the connecting ear 210 and the wall surface 300 is greater than or equal to the distance between the connecting ear 210 and the open end, which further avoids interference between the first receiving space 71 and the connecting ear 210.
[0079] Unlike traditional mechanical switches, the smart switch 100 is triggered by button 31 to activate electronic switch 21. Relay 82 responds to the activation of electronic switch 21 and controls the on / off state. The circuit of smart switch 100 generally includes high-voltage and low-voltage circuits. Relay 82 and power module are located in the high-voltage circuit, and electronic switch 21 is located in the low-voltage circuit. The first circuit board 2 can be understood as the circuit board carrying the low-voltage circuit.
[0080] like Figure 1 The diagram shown is a schematic representation of the overall structure of an intelligent switch 100 according to an embodiment of the present invention. Figure 2 The image shown is an exploded view of the smart switch 100. Figure 2 The right side is an exploded view of panel assembly 110. The smart switch 100 provided by this utility model can be a smart switch 100 with a screen or a smart switch 100 without a screen. This utility model is described in detail using a smart switch 100 with a screen as an example, but the protection scope of this utility model is not limited to the smart switch 100 with a screen.
[0081] like Figure 4 The image shown is a front view of the smart switch 100. The cut sections in each cross-sectional view are marked. Figure 5 and Figure 6 This is a cross-sectional view of the smart switch 100 at part AA. Figure 10 This is a three-dimensional sectional view of the BB section when the middle shell 1 and the bottom shell 7 are installed into the junction box 200. Figure 17 This is a partial enlarged view of the cross-sectional view of panel assembly 110 at the CC region. Figure 19 This is a partial enlarged view of the cross-sectional view of panel assembly 110 and bottom shell 7 at the DD region.
[0082] Furthermore, such as Figure 5 and Figure 6 As shown, the first circuit board 2 is housed in the first sunken space 113, and then in the first receiving space 71. That is, the first circuit board 2 is indirectly sunk into the bottom shell 7 through the first sunken space 113, further reducing the thickness of the panel assembly 110 protruding from the wall.
[0083] Furthermore, such as Figure 11 As shown, an electronic switch 21 is provided on the side of the first circuit board 2 facing away from the bottom shell 7. The electronic switch 21 is accommodated in the first recessed space 113, further reducing the thickness of the panel assembly 110 protruding from the wall. The electronic switch 21 being accommodated in the first recessed space 113 can mean that the electronic switch 21 is completely submerged in the first recessed space 113; or it can mean that only the lower half of the electronic switch 21 is submerged in the first recessed space 113, with the upper half protruding from the first recessed space 113. In an exemplary embodiment, as... Figure 19 As shown, the electronic switch 21 is completely submerged in the first recessed space 113, meaning that the electronic switch 21 does not extend beyond the range of the first recessed space 113 in the vertical direction. This ensures that the electronic switch 21 does not occupy the space above the partition plate 11, reducing the thickness of the panel assembly 110 protruding from the wall.
[0084] In some embodiments, such as Figure 7 and Figure 8 As shown, the first accommodating space 71 is larger laterally than the second accommodating space 72; the first recessed space 113 is larger laterally than the second recessed space 114, thereby increasing the horizontal area of the first recessed space 113, making the area of the first circuit board 2 larger, and allowing the electronic switch 21 to be positioned closer to the edge. The lateral increase includes expanding to all sides, or expanding only to one side, two sides, or three sides. In an exemplary embodiment, the first accommodating space 71 expands laterally than the second accommodating space 72, and the first recessed space 113 expands laterally than the second recessed space 114.
[0085] like Figure 7As shown, due to the constraint of the connecting ear 210 of the dark box 200, the second accommodating space 72 needs to be provided with a concave structure at the corresponding position of the connecting ear 210 to avoid the connecting ear 210, which restricts the lateral area of the second accommodating space 72. The first accommodating space 71 is located above the connecting ear 210, avoiding interference with the connecting ear 210. Its lateral area is not restricted by the connecting ear 210. The area of the first accommodating space 71 is maximized within the accommodating range of the dark box 200, thereby increasing the lateral area of the first recessed space 113, making the first recessed space 113 sufficient to accommodate the first circuit board 2.
[0086] Furthermore, such as Figure 9 As shown, the first accommodating space 71 projects onto the first surface to form a first projected shape 121, and the second accommodating space 72 projects onto the first surface to form a second projected shape 123, with the first projected shape 121 encompassing the second projected shape 123; the first sunken space 113 projects onto the first surface to form a third projected shape 122, and the second sunken space 114 projects onto the first surface to form a fourth projected shape 124, with the third projected shape 122 encompassing the fourth projected shape 124. Wherein, in Figure 9 In the diagram, the outlines of the first projected image 121 and the second projected image 123 are marked with dashed lines, while the outlines of the third projected image 122 and the fourth projected image 124 are marked with solid lines. Figure 9 It can be seen that the first projection graphic 121, the third projection graphic 122, the second projection graphic 123, and the fourth projection graphic 124 form a relationship of one-to-one containment from the outside to the inside.
[0087] Furthermore, such as Figure 9 and Figure 10 As shown, the first projected pattern 121 is constructed as a square with a side length greater than 60 mm and less than 68 mm, thereby maximizing the lateral area of the first receiving space 71 within the accommodating range of the 86-cell 200. Furthermore, the depth of the first receiving space 71 is less than 5 mm to avoid interference between the bottom wall of the first receiving space 71 and the connecting lug 210 during installation of the bottom shell 7.
[0088] In some embodiments, such as Figure 10 and Figure 3 As shown, the bottom shell 7 is fixedly connected to the recessed box 200 on the wall 300 via a threaded connector 73. The nut of the threaded connector 73 is accommodated in the first accommodating space 71, making the area of the first accommodating space 71 larger. The threaded connector 73 can be a screw or other part with a threaded connection post. In an exemplary embodiment, the threaded connector 73 is constructed as a screw.
[0089] Furthermore, such as Figure 3and Figure 10 As shown, the first recessed portion 111 is provided with a nut receiving groove 116 at the corresponding position of the nut of the threaded connector 73, and the nut is received in the nut receiving groove 116. The nut receiving groove 116 is located on both sides of the first recessed portion 111 and is laterally recessed into the first recessed portion 111.
[0090] Furthermore, such as Figure 10 and Figure 11 As shown, the nut receiving groove 116 corresponds to a nut boss 117 formed within the first recessed space 113; wherein, the nut boss 117 is located on both sides of the first recessed space 113 and protrudes laterally from the first recessed space 113, and the nut receiving groove 116 is formed below the nut boss 117. Thanks to the small size of the nut, the nut boss 117 occupies a small space, thus minimizing the impact of the nut boss 117 on the area of the first recessed space 113.
[0091] Furthermore, such as Figure 18 and Figure 15 As shown, the panel assembly 110 also includes a screen 4 and three buttons 31 arranged side-by-side with the screen 4. The screen 4 and the buttons 31 are distributed horizontally. A screw nut boss 117 is located within the coverage area of the buttons 31. The first circuit board 2 is provided with three electronic switches 21, and the three buttons 31 respectively trigger the three electronic switches 21. The three buttons 31 are all located on the right side of the panel assembly 110, and are arranged sequentially along a first direction. Because the buttons 31 and the screen 4 are distributed horizontally, the area of the buttons 31 is very small. The screw nut boss 117 is located below the middle button 31. Due to the space occupied by the screw nut boss 117, the middle electronic switch 21 is closer to the screen 4. Figure 19 It is known that the closer the electronic switch 21 is to the screen 4, the closer the distance between the electronic switch 21 and the pivot 321 of the button 31, and the longer the pressing stroke required for the button 31 to trigger the electronic switch 21. When the electronic switch 21 is too close to the screen 4, the button 31 will not be able to trigger the electronic switch 21. To ensure that the electronic switch 21 can be triggered normally, in this embodiment, as follows... Figure 11 As shown, the distance between the electronic switch 21 located in the middle and the nut boss 117 is less than 2mm, so that the distance between the electronic switch 21 and the pivot 321 of the button 31 meets the requirements, and avoids the button 31 from failing to trigger the electronic switch 21 due to insufficient pressing stroke.
[0092] In some embodiments, such as Figure 6 and Figure 8As shown, the first circuit board 2 is provided with a wireless communication module 23 facing the second sunken space 114. The second sunken space 114 sinks down to form a third sunken space 119 at the position corresponding to the wireless communication module 23. A part of the wireless communication module 23 is accommodated in the third sunken space 119 to further reduce the thickness of the panel assembly 110 protruding from the wall.
[0093] Furthermore, such as Figure 12 The diagram shows the front and back structures of the first circuit board 2. The wireless communication module 23 is located on the back of the first circuit board 2. The wireless communication module 23 includes an antenna 231, which is positioned at the edge of the first circuit board 2. A communication notch 241 is formed on the first circuit board 2 directly opposite the antenna 231 to prevent the first circuit board 2 from shielding the wireless signal. Figure 12 Only some of the electronic components are shown; the others are not.
[0094] Furthermore, such as Figure 15 As shown, the screen 4 includes a screen body 41 and a glass cover 42 covering the screen body 41. The content displayed on the screen body 41 is displayed to the outside through the glass cover 42. To avoid the screen body 41 from blocking wireless signals, such as... Figure 13 As shown, the screen body 41 and the first circuit board 2 are indicated by dashed lines, the wireless communication module 23 is indicated by bold lines, and the antenna 231 is located on the side of the first circuit board 2 away from the screen body 41. The antenna 231 and the screen body 41 do not overlap in the first projection direction, which is the direction from the panel assembly 110 towards the bottom shell 7. Figure 13 The view direction. Furthermore, the antenna 231 is positioned within the coverage area of the button 31.
[0095] In one embodiment, the screen 4 is a touch screen.
[0096] Furthermore, such as Figure 15 and Figure 16 As shown, the screen body 41 is attached to and fixedly connected to the glass cover plate 42. The back of the glass cover plate 42 is coated with black paint 425, which is used to cover the components inside the glass cover plate 42. However, the black paint 425 is not applied to the infrared emitting unit 27, the infrared receiving unit 28, the light sensing unit 29, and the corresponding positions of the display area of the screen 4. A transmission window 421 is formed on the back of the glass cover plate 42 at the corresponding position of the infrared emitting unit 27, a receiving window 422 is formed at the corresponding position of the infrared receiving unit 28, a light sensing window 423 is formed at the corresponding position of the light sensing unit 29, and a display window 424 is formed at the corresponding position of the display area.
[0097] In existing technologies, buttons are typically positioned above the middle shell, while the control circuit board is positioned below it. The buttons are movably connected to the middle shell, and the partition plate is fixedly connected to the bottom of the middle shell as an independent component. The control circuit board is positioned between the middle shell and the partition plate. This design results in the buttons, middle shell, control circuit board, partition plate, bottom shell, and top plate being stacked in the thickness direction, leading to a relatively thick panel assembly protruding from the wall.
[0098] To solve the above problems, in the embodiments of this utility model, such as Figure 18 and Figure 19 As shown, the panel assembly 110 includes a middle shell 1, and the partition plate 11 is integrally formed on the middle shell 1; wherein, the partition plate 11 is used to separate the first circuit board 2 and the bottom shell 7, that is, in the thickness direction, the button 31, the first circuit board 2, and the partition plate 11 are stacked and arranged, as shown. Figure 19 As shown, thanks to the fact that the first circuit board 2 is completely sunken into the first sunken space 113, the thickness of the panel assembly 110 protruding from the wall 300 is only the sum of the thicknesses of the button 31, the partition plate 11, and the bottom and top plates 74, which greatly reduces the thickness of the panel assembly 110 protruding from the wall 300.
[0099] like Figure 7 As shown, the bottom shell top plate 74 can be understood as a plate extending laterally from the top of the bottom shell 7.
[0100] Furthermore, such as Figure 5 and Figure 6 As shown, the panel assembly 110 also includes a screen 4, which is disposed on the side of the first circuit board 2 opposite to the second recessed portion 112. Since the partition plate 11 is integrally formed on the middle shell 1, i.e., no partition plate is provided between the middle shell 1 and the first circuit board 2 and the screen 4, the gap between the first circuit board 2 and the screen 4 can accommodate more electronic components. Based on this, electronic components (such as electronic switches 21, ribbon cable connection terminals 22, etc.) disposed on the upper surface of the first circuit board 2 can be completely recessed into the first recessed space 113, from... Figure 5 As can be seen, when the screen 4 is placed on the middle shell 1, the gap between the two ends of the partition plate 11 and the screen body 41 in the thickness direction is very small. The thickness of the panel assembly 110 protruding from the wall surface 300 is only the sum of the thicknesses of the glass cover plate 42, the screen body 41, the partition plate 11, and the bottom shell top plate 74, which greatly reduces the thickness of the panel assembly 110 protruding from the wall surface 300.
[0101] In some embodiments, an insulating sheet (not shown) is laid between the first circuit board 2 and the screen body 41 to prevent the first circuit board 2 from causing electrostatic interference to the screen body 41. In an exemplary embodiment, the insulating sheet is a Mylar sheet.
[0102] Furthermore, such as Figure 1and Figures 18-20 As shown, the panel assembly 110 also includes a button assembly 3, which includes multiple buttons 31 and a pivot 321. The first circuit board 2 is provided with electronic switches 21 corresponding to the buttons 31. Each button 31 can be pressed and pivoted based on the pivot 321, thereby triggering the corresponding electronic switch 21. The buttons 31 are arranged side by side with the screen 4, and the pivot 321 is located at the end of the button 31 closer to the screen 4, so that the pressing movement of the button 31 is more adapted to the user's usage habits. Specifically: Figure 1 As shown, since the button 31 and the screen 4 are arranged side by side, when the user presses the button 31, in order to avoid the user's hand covering the screen 4, the user will tend to press the end of the button 31 that is away from the screen 4. Since the pivot 321 of the button 31 is set at the end of the button 31 that is closer to the screen 4, the pressing feel of the end of the button 31 that is away from the screen 4 is the best, which is just right for the user's usage habits and gives the user a better pressing feel.
[0103] Furthermore, such as Figure 19 As shown, the button 31 is provided with a hook 311, which is engaged with the middle shell 1 to limit the button 31. In the prior art, the hook 311 is usually located at the tail end of the button 31. However, this design is not suitable for the ultra-thin panel structure provided by this utility model. The reason is that when the button 31 is pressed, the hook 311 will move downward with the button 31. Due to the ultra-thin design of the panel assembly 110, if the hook 311 moves downward too much, it will collide with the bottom shell top plate 74, thereby preventing the button 31 from being pressed further. There is a high probability that the button 31 will not trigger the electronic switch 21. The bottom shell top plate 74 can be understood as a horizontal extension plate at the top of the bottom shell 7, and both ends of the middle shell 1 are engaged with the bottom shell top plate 74.
[0104] To address the problem of the bottom shell top plate 74 blocking the button 31 from triggering the electronic switch 21, this embodiment of the invention designs a hook structure adapted to the ultra-thin panel assembly 110, such as... Figure 23 As shown, in the second direction, the distance between the end of the button 31 away from the rotating shaft 321 and the rotating shaft 321 is set as L1, and the distance between the hook 311 and the rotating shaft 321 is set as L2; then L2 satisfies the relationship: L2≤L1*3 / 4; the second direction is set as the direction in which the button 31 faces the screen 4. In this embodiment of the present invention, by shortening the distance between the hook 311 and the rotating shaft 321, the movement stroke of the hook 311 is reduced during the pressing of the button 31, so that the hook 311 will not touch the bottom shell top plate 74 within the movement stroke, ensuring that the button 31 can trigger the electronic switch 21 within the pressing stroke.
[0105] The measurement methods for L1 and L2 are as follows: Figure 23 As shown, L1 is the distance from the tail end of button 31 to the center position of pivot 321, and L2 is the distance from the end of hook 311 near pivot 321 to the center position of pivot 321.
[0106] Furthermore, such as Figure 23 As shown, compared to the hook 311 located in the middle, the hooks 311 at both ends are closer to the pivot 321. This ensures that when the corners of the buttons 31 at both ends are pressed, the hooks 311 will not touch the top plate 74 of the bottom shell, and the buttons 31 can successfully trigger the electronic switch 21. In the exemplary embodiment, the distance L2 between the hooks 311 at both ends and the pivot 321 is 0.58*L1, and the distance L2 between the hooks 311 located in the middle and the pivot 321 is 0.66*L1.
[0107] Furthermore, due to the limitations of the ultra-thin panel design, the downward movement space of the latch 311 of button 31 is relatively small. When the latch 311 moves downward, it easily touches the top plate 74 of the bottom shell, causing the button 31 to be obstructed from being pressed. To increase the downward movement space of the latch 311, such as... Figure 19 and Figure 18 As shown, the partition plate 11 is provided with a locking step 118 that cooperates with each of the hooks 311. The hooks 311 are locked into the locking step 118. The locking step 118 protrudes upward from the partition plate 11, so that there is enough space between the locking step 118 and the bottom shell top plate 74. When the button 31 is pressed, the hook 311 can move within the space of the locking step 118, thereby avoiding insufficient pressing stroke that would prevent the electronic switch 21 from being triggered.
[0108] In some embodiments, such as Figure 23 As shown, each of the buttons 31 is provided with a trigger post 312 for triggering the electronic switch 21. There are three buttons 31 arranged sequentially along a first direction. The applicant discovered that, because the electronic switch 21 is located within the first recessed space 113, and is restricted by the first recessed space 113, the electronic switch 21 is relatively close to the rotating shaft 321, resulting in a short travel distance of the trigger post 312. When the corner positions of the buttons 31 at both ends are pressed, because the pressing position is far from the rotating shaft 321, the travel distance of the trigger post 312 may be insufficient to trigger the electronic switch 21. To solve this problem, in this embodiment of the utility model, as... Figure 23 As shown, in the second direction, the distance between the trigger pins 312 at both ends and the rotating shaft 321 is greater than the distance between the trigger pin 312 at the middle position and the rotating shaft 321, so that the travel of the trigger pins 312 at both ends is longer, so as to ensure that the electronic switch 21 can be successfully triggered when the corner position of the button 31 at both ends is pressed.
[0109] The distance between the trigger pin 312 and the rotating shaft 321 can be understood as the distance between the center position of the trigger pin 312 and the center position of the rotating shaft 321 in the second direction. Figure 23 L3 in the middle.
[0110] In some embodiments, such as Figure 19 As shown, button 31 remains in contact with electronic switch 21 in both the pressed and unpressed states, and button 31 is reset by the spring force of electronic switch 21. Notably, button 31 does not require an additional reset structure, which simplifies the structure of panel assembly 110, reduces the force required to press, and improves the tactile feel. Furthermore, because button 31 is always in contact with electronic switch 21, its trigger stroke is shorter, the trigger is more sensitive, and the trigger force feedback is clearer.
[0111] In some embodiments, such as Figure 2 and Figure 3 As shown, a second circuit board 8 is disposed within the second accommodating space 72 of the bottom shell 7. The second circuit board 8 is used to house a power module. An insulating cover plate 6 is disposed between the second circuit board 8 and the partition plate 11, and the second circuit board 8 is confined within the second accommodating space 72 by the insulating cover plate 6. The insulating cover plate 6 is snapped onto the side wall of the bottom shell 7. The insulating cover plate 6 has a first transmission hole 61, and the partition plate 11 has a second transmission hole 1121. The second circuit board 8 and the first circuit board 2 are connected by a pin header 25 and a socket header 81. The pin header 25 passes through the first transmission hole 61 and the second transmission hole 1121 and connects to the socket header 81. One of the first circuit board 2 and the second circuit board 8 is provided with a pin header 25, and the other is provided with a socket header 81. When the panel assembly 110 is installed on the bottom shell 7, the pin header 25 is inserted into the socket header 81 to achieve electrical conductivity. The second circuit board 8 carries a high-voltage circuit. The power module converts the high-voltage electricity into low-voltage electricity. The second circuit board 8 transmits the low-voltage electricity to the first circuit board 2 via pin header 25 and socket 81 for powering the first circuit board 2. The panel assembly 110 covers the bottom shell 7. The second circuit board 8 is equipped with a relay 82. The electrical signals from the first circuit board 2 are transmitted to the second circuit board 8 via pin header 25 and socket 81. The relay 82 switches between on and off states in response to the triggering of the electronic switch 21.
[0112] like Figures 18-22As shown in this embodiment of the present invention, in order to achieve an ultra-thin panel design, the first circuit board 2 is placed above the middle shell 1. Since the button 31 and the screen 4 are arranged side by side, the connection structure 32 of the button 31 is difficult to directly snap onto the middle shell 1. A new connection scheme needs to be designed to limit the connection structure 32 of the button 31. Therefore, in some embodiments, the panel assembly 110 includes a middle shell assembly 120, a limiting bracket 5, and a button assembly 3. The limiting bracket 5 is detachably installed on the middle shell assembly 120. The button assembly 3 includes a connection structure 32. The limiting bracket 5 includes a limiting part 51. The connection structure 32 is detachably installed on the limiting part 51. When the limiting bracket 5 is installed on the middle shell assembly 120, the connection structure 32 is limited by the limiting part 51 and the middle shell assembly 120.
[0113] This utility model adopts a limiting bracket 5 to limit the connection structure 32 of the button 31, which solves the problem that the connection structure 32 is difficult to directly snap onto the middle shell 1. Moreover, in this embodiment, the connection structure 32 is limited by the limiting bracket 5 and the middle shell assembly 120, which makes the limiting more stable and can prevent the connection structure 32 from detaching from the middle shell 1.
[0114] The middle shell assembly 120 includes a middle shell 1 and a first circuit board 2. The connection structure 32 being limited by the limiting part 51 and the middle shell assembly 120 can be understood as the connection structure 32 being limited between the limiting part 51 and the middle shell 1, and / or the connection structure 32 being limited between the limiting part 51 and the first circuit board 2. The detachable connection can be a snap-fit, screw connection, or other connection method. The connection structure 32 can be a rotating shaft 321, a connecting block, or other structures.
[0115] Furthermore, such as Figure 18 and Figure 19 As shown, the direction in which the connecting structure 32 is installed on the limiting portion 51 is opposite to the direction in which the limiting bracket 5 is installed on the middle shell assembly 120, so that the connecting structure 32 is more stably limited. Specifically, in an exemplary embodiment, as... Figure 19 As shown, the connecting structure 32 is engaged with the limiting part 51 from bottom to top, as... Figure 18 As shown, the limiting bracket 5 is engaged with the middle shell assembly 120 from top to bottom. When the limiting bracket 5 is engaged with the middle shell assembly 120, the lower end of the limiting part 51 is blocked by the middle shell assembly 120, which effectively prevents the connecting structure 32 from disengaging downward from the limiting part 51.
[0116] In some embodiments, such as Figure 19As shown, the connecting structure 32 includes a rotating shaft 321, and the limiting part 51 includes an arc-shaped slot 511. The slot 511 has a slot inlet at its lower end, and the rotating shaft 321 is inserted into the slot 511 through the slot inlet. When the limiting bracket 5 is installed on the middle shell assembly 120, the slot inlet of the slot 511 is closed by the middle shell assembly 120, and the rotating shaft 321 is limited between the slot 511 and the middle shell assembly 120. The rotating shaft 321 is located on the side of the button assembly 3, which includes multiple buttons 31. Each button 31 can pivot based on the rotating shaft 321. Even when the slot inlet of the slot 511 is closed by the middle shell assembly 120, a small rotational gap remains between the slot 511 and the rotating shaft 321 to ensure smooth rotation of the rotating shaft 321.
[0117] The middle shell assembly 120 includes a middle shell 1 and a first circuit board 2. In some embodiments, the card inlet of the card slot 511 may be closed by the middle shell 1 and / or the first circuit board 2.
[0118] In existing technologies, the pivot of a button is typically directly snapped into the middle shell. The middle shell's limiting effect on the pivot is weak, and when the end of the button is pressed downwards, the pivot tends to tilt upwards. If the pivot shifts upwards during button pressing, it not only affects the button's tactile feedback but also risks preventing the electronic switch from being triggered. In this embodiment, thanks to the pivot 321 being snapped into the slot 511 from bottom to top, and the lower end of the slot 511 being sealed by the middle shell assembly 120, the slot 511 prevents the pivot 321 from shifting upwards during button pressing, ensuring the electronic switch 21 is triggered normally.
[0119] In some embodiments, such as Figure 18 and Figure 19 As shown, the limiting bracket 5 is installed on the middle shell 1; the lower surface of the first circuit board 2 is supported by the middle shell 1, and the upper surface is abutted by the limiting bracket 5. The connecting structure 32 is limited by the limiting bracket 5 and the first circuit board 2. That is, the first circuit board 2 is pressed tightly against the middle shell 1 by the limiting bracket 5. The limiting bracket 5 is not only used to limit the connecting structure 32, but also to limit the first circuit board 2 in the vertical direction, which simplifies the limiting structure and improves assembly efficiency.
[0120] Furthermore, such as Figure 18 and Figure 8As shown, the middle shell 1 is provided with multiple first buckles 13 for engaging the first circuit board 2 and at least one first positioning post 14 for positioning the first circuit board 2. The first end of the first circuit board 2 is engaged by the first buckles 13, and the second end of the first circuit board 2 away from the first end is positioned by the first positioning post 14. The limiting bracket 5 presses against the second end of the first circuit board 2. That is, both ends of the first circuit board 2 are vertically limited by the first buckles 13 and the limiting bracket 5, respectively. During assembly, simply insert the first end of the first circuit board 2 obliquely under the first buckles 13, then place the first circuit board 2 horizontally so that the first positioning post 14 is inserted into the first circuit board 2, and finally install the limiting bracket 5 onto the middle shell 1 so that the second end of the first circuit board 2 is pressed and limited by the limiting bracket 5, thus completing the assembly of the first circuit board 2, which is convenient and quick.
[0121] Furthermore, such as Figure 8 and Figure 11 As shown, the first circuit board 2 has first positioning holes 26 at corresponding positions of each positioning post. The positioning posts are inserted into the first positioning holes 26 to achieve horizontal positioning of the first circuit board 2. There are two first positioning posts 14, both located at the second end of the first circuit board 2. The two positioning posts are respectively located near the first edge and the second edge of the first circuit board 2 to improve the horizontal positioning accuracy of the first circuit board 2. The first edge and the second edge are located at the third end and the fourth end of the first circuit board 2, respectively. The direction from the third end to the fourth end is perpendicular to the direction from the first end to the second end.
[0122] Furthermore, such as Figure 8 and Figure 11 As shown, the middle shell 1 is provided with a fourth buckle 15 facing upward. The fourth buckle 15 is engaged with the edge of the first circuit board 2 near the pin header 25 to restrict the upward movement of the first circuit board 2 and prevent the first circuit board 2 from being pushed up by the pin header 25.
[0123] Furthermore, such as Figure 22 and Figure 19 As shown, the limiting bracket 5 is provided with multiple abutting platforms 52. The limiting bracket 5 presses against the first circuit board 2 through the abutting platforms 52 to improve the positional accuracy of the first circuit board 2 and ensure that the electronic switch 21 is accurately triggered.
[0124] In some embodiments, such as Figure 18As shown, the limiting bracket 5 includes a long strip-shaped frame 53. The middle and both ends of the long strip-shaped frame 53 are horizontally positioned with the middle shell 1 and respectively snapped into the middle shell 1 to prevent deformation of the long strip-shaped frame 53. The positioning of the long strip-shaped frame 53 with the middle shell 1 locks its horizontal position, while the snapping of the long strip-shaped frame 53 with the middle shell 1 locks its vertical position, thus stably and accurately fixing the long strip-shaped frame 53 to the middle shell 1. It is worth mentioning that setting the snapping position near the positioning position results in higher snapping stability, higher positional accuracy of the limiting bracket 5, and correspondingly, higher positional accuracy of the button 31.
[0125] Furthermore, such as Figure 18 and Figure 21 As shown, a second positioning post 531 is provided in the middle of the elongated frame 53. The second positioning post 531 is inserted into the middle shell 1 to achieve the positioning of the middle of the elongated frame 53. Positioning grooves 532 are respectively provided at both ends of the elongated frame 53. The middle shell 1 is provided with positioning protrusions 161 that are adapted to the positioning grooves 532. The positioning protrusions 161 are embedded in the positioning grooves 532 to achieve the positioning of both ends of the elongated frame 53.
[0126] Furthermore, such as Figure 18 and Figure 8 As shown, the middle shell 1 is provided with a second positioning hole 162, and the second positioning post 531 is inserted into the second positioning hole 162 to achieve the mid-positioning of the elongated frame 53. The second positioning hole 162 is close to the second buckle 17 and is integrated with the second buckle 17.
[0127] Furthermore, such as Figure 18 As shown, the side wall of the first sunken space 113 is provided with a positioning ridge 1131. The elongated frame 53 protrudes downward at the corresponding position in the first sunken space 113 to form a protruding part 535. The end faces of the two ends of the protruding part abut against the positioning ridge 1131 to achieve positioning of the limiting bracket 5 in the first direction. Further, as Figure 14 As shown, the protruding part 535 protrudes horizontally from the elongated frame 53 in the direction of the screen 4. When the limiting bracket 5 is installed on the middle shell 1, the protruding part 535 sinks into the first recessed space 113, and the top surface of the protruding part 535 is flush with the top of the first recessed space 113. Consequently, the bottom surface of the screen receiving groove 191 is flush with the top surface of the protruding part 535, and the screen body 41 is supported by the bottom surface of the screen receiving groove 191 and the top surface of the protruding part 535.
[0128] Furthermore, such as Figure 18As shown, the protruding part 535 is provided with a fifth buckle 536 at both ends, and the side wall of the first recessed space 113 is provided with a sixth buckle 1132 that matches the fifth buckle 536. The fifth buckles 536 at both ends of the protruding part 535 are respectively engaged with the sixth buckle 1132.
[0129] Furthermore, such as Figure 18 and Figure 12 As shown, the sixth buckle 1132 is at the same horizontal height as the first circuit board 2. The two sides of the first circuit board 2 are respectively provided with snap-fit notches 242 at the corresponding positions of the sixth buckle 1132. The sixth buckle 1132 is accommodated in the snap-fit notches 242. The fifth buckle 536 is inserted into the snap-fit notches 242 and then snaps into the sixth buckle 1132.
[0130] In some embodiments, such as Figure 18 and Figure 8 As shown, the middle shell 1 is provided with a second buckle 17 for engaging the middle part of the elongated frame 53, and a third buckle 18 for engaging both ends of the elongated frame 53, resulting in higher engagement stability. Furthermore, the openings of the two third buckles 18 face each other, while the opening of the second buckle 17 faces the button 31. Further, as... Figure 18 and Figure 21 As shown, a central buckle 534 is provided in the middle of the elongated frame 53, and the second buckle 17 is engaged with the corresponding central buckle 534. End buckles 533 are provided at both ends of the elongated frame 53, and the third buckle 18 is engaged with the corresponding end buckles 533.
[0131] In some embodiments, such as Figure 14 and Figure 15 As shown, the upper end of the middle shell assembly 120 has a first end face, and the upper surface of the limiting bracket 5 is flush with the first end face of the middle shell assembly 120; the panel assembly 110 also includes a screen 4, which covers the first end face of the middle shell assembly 120 and the upper surface of the limiting bracket 5, and the lower surface of the limiting bracket 5 is supported by the middle shell 1. The limiting bracket 5 being covered by the screen 4 makes the connection between the limiting bracket 5 and the middle shell 1 more stable, and at the same time, the screen 4 is more stably supported.
[0132] Furthermore, such as Figure 14As shown, the first, second, and third sides of the middle shell 1 are respectively provided with supporting edges 19 protruding upwards. These three supporting edges 19 are connected as a whole, and the three supporting edges 19 and the limiting bracket 5 enclose a square frame, forming a screen receiving groove 191 inside the square frame. The first end face is the upper surface of the supporting edge 19. The screen 4 includes a screen body 41 and a glass cover plate 42 covering the upper surface of the screen body 41. The screen body 41 and the glass cover plate 42 are fixedly connected. The back of the glass cover plate 42 is attached with adhesive 43, and the glass cover plate 42 is attached to the upper surface of the supporting edge 19 and the upper surface of the limiting bracket 5 by the adhesive 43. The screen body 41 is accommodated in the screen receiving groove 191.
[0133] Furthermore, a ribbon cable connection terminal 22 is provided on the upper surface of the first circuit board 2. The ribbon cable connection terminal 22 is located below the screen body 41. A ribbon cable is provided at the end of the screen body 41. The screen body 41 is connected to the ribbon cable connection terminal 22 through the ribbon cable.
[0134] Furthermore, such as Figure 17 and Figure 18 As shown, the upper surface of the first circuit board 2 is abutted by the limiting bracket 5. The limiting bracket 5 is provided with a first through hole 54 and a second through hole 55. An infrared emitting unit 27 is provided in the first through hole 54 of the first circuit board 2. The infrared emitting unit 27 is used to emit infrared light. An infrared receiving unit 28 is provided in the second through hole 55 of the first circuit board 2. The infrared receiving unit 28 is used to receive infrared light. The infrared emitting unit 27 and the infrared receiving unit 28 form a distance sensing module. The infrared light of a specified wavelength emitted by the infrared emitting unit 27 is reflected back to the infrared receiving unit 28 by an external object. The infrared receiving unit 28 receives the infrared light of the specified wavelength. When an external object is in front of the panel assembly 110 and is relatively close to it, the intensity of the infrared light received by the infrared receiving unit 28 will exceed a certain threshold. The distance sensing module determines that a person is in front of the panel and is relatively close, so the main control module controls the screen 4 to light up. When the screen 4 and the button 31 are not operated for a period of time and the sensing module determines that no one is approaching the panel, the main control module controls the screen 4 to turn off. This achieves intelligent control of turning on the screen when someone is present and turning off the screen when someone leaves.
[0135] In one exemplary embodiment, the infrared emitting unit 27 is an infrared LED capable of emitting infrared light of a specified wavelength, and the infrared receiving unit 28 is an infrared receiver capable of receiving the infrared light emitted by the LED. A black IR layer is sprayed onto the back of the glass cover 42 at the receiving window 422, making the transmittance of infrared light through the glass cover 42 much greater than the transmittance of natural light, thus preventing ambient light from interfering with the infrared receiving unit 28. Furthermore, the black IR layer is black in appearance, thereby visually concealing the receiving window 422.
[0136] Furthermore, such as Figure 17 As shown, the sidewall of the first through-hole 54 surrounds the infrared emitting unit 27 to block the infrared light emitted by the infrared emitting unit 27 from propagating to the side, thus preventing the infrared light from propagating from inside the panel to the infrared receiving unit 28 and causing the infrared receiving unit 28 to be falsely triggered. Furthermore, the gap between the sidewall of the first through-hole 54 and the first circuit board 2 is extremely small to reduce the amount of infrared light irradiating into the panel and prevent the infrared receiving unit 28 from being falsely triggered.
[0137] Furthermore, the first circuit board 2 has a photosensitive unit 29 disposed between the infrared emitting unit 27 and the infrared receiving unit 28. The limiting bracket 5 has a third through hole 58 at the corresponding position of the photosensitive unit 29, and the photosensitive unit 29 is accommodated in the third through hole 58. Ambient light is irradiated onto the photosensitive unit 29 through the photosensitive window 423, and the photosensitive unit 29 is used to sense the brightness of the ambient light. In one embodiment, the photosensitive unit 29 is a photoresistor. Disposing the photosensitive unit 29 between the infrared emitting unit 27 and the infrared receiving unit 28 can prevent infrared light from penetrating the sidewalls of the first through hole 54 and the second through hole 55 to irradiate the infrared receiving unit 28, thus avoiding false triggering of the infrared receiving unit 28.
[0138] Furthermore, such as Figure 17 and Figure 18 As shown, a cylindrical light guide post 581 is disposed inside the third through hole 58, which is used to guide external ambient light into the light sensing unit 29. Further, the light guide post 581 is embedded in the third through hole 58 from the outside, and there is an interference fit between the light guide post 581 and the third through hole 58.
[0139] Furthermore, the distance between the infrared emitting unit 27 and the infrared receiving unit 28 is greater than 10 mm to further prevent infrared light from propagating from inside the panel to the infrared receiving unit 28. In one embodiment, the distance between the infrared emitting unit 27 and the infrared receiving unit 28 is 16 mm.
[0140] Furthermore, such as Figure 21 and Figure 22 As shown, the button assembly 3 includes a plurality of buttons 31 and an extension arm 331 extending from the side of each button 31. The connecting structure 32 includes a pivot 321, which is disposed on the extension arm 331. The limiting part 51 includes an arc-shaped slot 511, and the pivot 321 is engaged with the slot 511. The pivot 321 is limited between the slot 511 and the first circuit board 2. The first circuit board 2 is provided with electronic switches 21, the number of which corresponds to the number of buttons 31. Each button 31 can be pressed and pivoted based on the pivot 321, thereby triggering the corresponding electronic switch 21.
[0141] The extension arm 331 has a certain degree of elasticity. In this embodiment, the pivot 321 is set in the extension arm 331. The elasticity of the extension arm 331 weakens the limiting effect of the pivot 321, and the rotational joint formed by the pivot 321 becomes a weak limiting mechanism. The button 31 can tilt to both sides while pivoting based on the pivot 321. The advantage of this design is that no matter whether the user presses the end of the button 31 or the sides of the button 31, the button 31 can tilt towards the pressed part. This not only makes it easier to trigger the electronic switch 21, but also increases the triggerable area of the button 31 and improves the pressing feel.
[0142] In some embodiments, such as Figure 20 As shown, the button assembly 3 includes a plurality of buttons 31 and a connector 33 connecting the buttons 31 together. The buttons 31 are arranged side-by-side along a first direction, and the connector 33 extends outward from the side of each button 31 facing a second direction. The second direction is perpendicular to the first direction and parallel to the pressing surface of the button 31. The first and second directions are already... Figure 20 The buttons 31 are connected as a whole by connector 33, ensuring consistent gaps between them and facilitating assembly. Notably, because connector 33 extends outward from the second side of the buttons 31, it is located outside the button 31 distribution area, reducing the linkage between buttons 31 and preventing adjacent buttons 31 from moving together with the pressed button 31, thus avoiding poor tactile feedback and accidental triggering.
[0143] It is worth noting that the connector 33 extends from the side of the button 31 facing the second direction, but the extension direction is not necessarily the second direction. The extension direction can be at a certain angle to the second direction.
[0144] Furthermore, such as Figure 20As shown, the connector 33 includes the extension arm 331 and the connecting arm 332 that connects the extension arms 331 to each other. The limiting bracket 5 is disposed on the side of the button 31 facing the second direction; wherein, thanks to the fact that both the connecting arm 332 and the extension arm 331 are long strip structures with good elasticity, the connector 33 is formed by the extension arm 331 and the connecting arm 332, giving the connector 33 good deformation performance, thereby making the linkage between the buttons 31 weaker and preventing the buttons 31 from moving together with the adjacent pressed buttons 31.
[0145] exist Figure 20 In the illustrated embodiment, two adjacent buttons 31 are connected as one unit by a connecting arm 332, and three buttons 31 are connected as one unit by two connecting arms 332, which are not connected. In some other embodiments (not shown in the figure), each button 31 extends two extension arms 331, and a connecting arm 332 connects all the extension arms 331 as one unit.
[0146] Furthermore, such as Figure 19 and Figure 20 As shown, the extension arm 331 extends toward a third direction, which is inclined downward relative to the second direction, so that the pivot 321 is located diagonally below the button 31, and the limiting bracket 5 can be arranged side by side with the button 31. The pivot 321 is limited by the limiting bracket 5 and the first circuit board 2.
[0147] Furthermore, such as Figure 20 As shown, each end of the connecting arm 332 is connected to an extension arm 331, and the connecting arm 332 and the extension arm 331 together form an "E"-shaped structure. This "E"-shaped structure can be understood as a structure resembling the shape of an "E," including three approximately parallel horizontal beams and a longitudinal beam connected to the left end of each horizontal beam. The connecting piece 33 of the "E"-shaped structure has better deformation performance, further reducing the linkage between the buttons 31, making the movements of the buttons 31 independent, and improving the tactile feel of pressing the buttons 31.
[0148] Furthermore, such as Figures 19-22As shown, the connecting structure 32 includes a pivot 321, which is limited by the limiting bracket 5 to the middle shell assembly 120. The button 31 can pivot based on the pivot 321. The connecting member 33 includes an extension arm 331 extending from the button 31, and the pivot 321 is disposed on the extension arm 331. Compared to disposing the pivot 321 on the connecting arm 332, this embodiment disposing the pivot 321 on the extension arm 331 has the following advantages: 1. Each extension arm 331 can be equipped with a pivot 321, resulting in a greater number of pivots 321 and more stable button movement; 2. Each pivot 321 is disposed on a different extension arm 331, reducing the linkage between pivots 321; 3. Disposing the pivot 321 on the extension arm 331 helps to cut off the force transmission between buttons 31, making the movement of buttons 31 independent and improving the button pressing feel.
[0149] Furthermore, such as Figure 23 As shown, each of the buttons 31 is provided with a trigger post 312 for triggering the electronic switch 21. The button 31 can be pressed and pivoted based on the rotating shaft 321, thereby triggering the corresponding electronic switch 21. In the second direction, the distance between the end of the button 31 furthest from the rotating shaft 321 and the rotating shaft 321 is set as L1, and the distance between the trigger post 312 and the rotating shaft 321 is set as L3. L3 satisfies the relationship: L3 < 1 / 2L1, making the button 31 a force-saving lever, thus requiring less effort to trigger the electronic switch 21. The measurement methods for L1 and L3 are as follows: Figure 23 As shown, L1 is the distance from the end of button 31 to the center of pivot 321, and L3 is the distance from the center of trigger post 312 to the center of pivot 321.
[0150] Furthermore, in the second direction, the distance L3 between the trigger pins 312 at both ends and the rotating shaft 321 is greater than the distance L3 between the trigger pin 312 at the middle position and the rotating shaft 321, so that the travel of the trigger pins 312 at both ends is longer, so as to ensure that the electronic switch 21 can be successfully triggered when the corner position of the button 31 at both ends is pressed.
[0151] In some embodiments, such as Figures 20-22As shown, the connector 33 is constructed in an "E" shape. Each end of the connector 33 is connected to a button 31, and the middle and one end of the connector 33 are connected to the same button 31. A hollow area 34 is formed between the connector 33 and the button 31. The limiting bracket 5 includes a long strip-shaped frame 53 extending along the first direction, and a blocking rod 56 extending from the long strip-shaped frame 53. The blocking rod 56 is located at the corresponding position of the gap between the two buttons 31, and the extension direction of the blocking rod 56 is parallel to the extension direction of the gap. During assembly, the blocking rod 56 of the limiting bracket 5 passes through the hollow area 34 and is positioned directly below the gap between the two buttons 31. The rotating shaft 321 is snapped onto the limiting bracket 5 from bottom to top. The limiting bracket 5 is installed on the middle shell assembly 120, thereby limiting the rotating shaft 321 within the middle shell assembly 120. Figure 22 This is a schematic diagram of the structure after the limit bracket 5 and the button assembly 3 are assembled. At this time, the blocking rod 56 is located directly below the gap between the buttons 31 and is used to block the gap.
[0152] Furthermore, the infrared receiving unit 28 and the light sensing unit 29 are disposed within the hollow area 34, thereby leaving more space in the panel assembly 110 for the screen 4 and maximizing the size of the display window 424.
[0153] In some embodiments, such as Figure 20 As shown, the left edge of the three buttons 31 forms a concave arc surface 313, and the right edge of the limiting bracket 5 is constructed as a convex arc surface 57. The convex arc surface 57 cooperates with the concave arc surface 313 to play an auxiliary positioning role when assembling the button assembly 3 and the limiting bracket 5. In addition, the blocking rod 56 can also play an auxiliary assembly role. Specifically, during assembly, the blocking rod 56 is first inserted into the hollow area 34 of the connector 33 to achieve coarse positioning between the blocking rod 56 and the button assembly 3. Then, the convex arc surface 57 on the right side of the limiting bracket 5 abuts against the concave arc surface 313 on the left side of the button 31. Due to the cooperation of the concave and convex arc surfaces, the limiting bracket 5 will slide to a position aligned with the center of the button assembly 3 under the action of the abutting force, thereby achieving precise positioning of the limiting bracket 5 in the first direction. Finally, the rotating shaft 321 is inserted into the limiting bracket 5 to complete the assembly, which greatly improves the assembly efficiency.
[0154] In another embodiment, such as Figure 24 As shown, this embodiment is similar to Figures 1-23 The difference in the illustrated embodiment is that: Figures 1-23 In the illustrated embodiment, the button assembly 3 is integrally injection molded from plastic material, and the button 31 is made of plastic. Figure 24In the illustrated embodiment, the button 31 is composed of a button bracket 314 and a button cover 315, which are made of different materials. The button cover 315 has higher hardness and rigidity, and is adhered to the upper surface of the button bracket 314 to enhance the deformation resistance of the button bracket 314 and improve the wear resistance and pressing feel of the button 31. Further, the button bracket 314, the extension arm 331, the connecting arm 332, the trigger post 312, the hook 311, and the pivot 321 are integrally formed from plastic, and the connecting wall 332 connects the button brackets 314 in pairs; the button cover 315 is made of tempered glass, and the number of button cover 315s is equal to the number of button brackets 314, with each button cover 315 correspondingly adhered to the upper surface of the button bracket 314. The lower surface of the button cover 315 and the upper surface of the button bracket 314 are both flat surfaces without protrusions. Further, in Figure 24 In the illustrated embodiment, the structure of the extension arm 331, the connecting arm 332, the trigger post 312, the latch 311, and the rotating shaft 321 is similar to... Figures 1-23 The embodiments are the same, and detailed technical details can be found above.
