Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a detachable switch. Background Technology

[0002] The internal circuit board of the free-adhesive switch contains a power supply component and a wireless communication module. The wireless communication module wirelessly connects to a gateway or electrical device, allowing wireless control of the device via the switch. Because the free-adhesive switch has a built-in power supply and does not require a high-voltage power connection, it can be freely pasted and installed in any desired location according to personal habits and preferences.

[0003] The existing adhesive switches are too thick, which does not conform to the current market trend. Utility Model Content

[0004] The purpose of this invention is to overcome at least one defect of the prior art and provide a thinner, more flexible adhesive switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The limiting rib includes at least one limiting notch spaced apart. The side wall of the second power mounting hole includes at least one limiting protrusion spaced apart. The at least one limiting notch and the at least one limiting protrusion are installed in a one-to-one correspondence to restrict the axial rotation of the covering surface. The side of the covering surface includes a first disassembly notch, or the side wall of the second power mounting hole includes a second disassembly notch, or the side of the covering surface includes a first disassembly notch and the side wall of the second power mounting hole includes a second disassembly notch, with the first disassembly notch and the second disassembly notch facing each other.

[0011] In one possible implementation, the side of the cover plate facing the circuit board is further provided with at least one elastic element and / or the side of the switch base facing the circuit board is provided with at least one elastic element, the at least one elastic element being driven to cooperate with the switch base.

[0012] In one possible implementation, the circuit board mounting slot includes at least one mounting post, and the circuit board includes at least one clearance notch, with the at least one mounting post corresponding to and limiting the at least one clearance notch in a one-to-one limiting fit.

[0013] In one possible implementation, the circuit board mounting slot includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected in sequence to limit the movement of the circuit board. The first sidewall and / or the second sidewall and / or the third sidewall and / or the fourth sidewall are provided with at least one third snap-fit ​​protrusion, which limits the movement of the circuit board along the thickness direction of the arbitrarily attached switch.

[0014] In one possible implementation, the cover plate is provided with at least one first rib on the side facing the switch base, and the at least one first rib is respectively opposite to the first side wall and / or the second side wall and / or the third side wall and / or the fourth side wall along the direction of the arbitrary switch thickness.

[0015] In one possible implementation, the cover plate has at least one first latch on the side facing the switch. The first latch includes two latch arms with a latch groove between them. The switch base has at least one latching shaft corresponding to the at least one first latch. The latching shaft is installed in the latch groove, and the two latch arms clamp the latching shaft, allowing the cover plate to be rotatably mounted to the switch base. The rotation axis of the cover plate is located on the plane of the switch base or the rotation axis of the cover plate is located inside the switch base.

[0016] In one possible implementation, the cover plate has a clearance groove on the side facing the switch base, the clearance groove being opposite to the power supply; and / or, the cover plate has at least one second pressure rib on the side facing the switch base, the second pressure rib abutting against the circuit board and restricting the movement of the circuit board along the thickness direction of the arbitrarily attached switch.

The positive terminal connector is connected to the side wall of the power source, and the negative terminal connector is connected to the bottom surface of the power source.

[0020] Compared to existing technologies, the customizable switch of this application includes a cover plate, a circuit board, and a switch base stacked sequentially. The cover plate and the switch base are rotatably mounted without a pressure plate. The micro switch on the circuit board is directly driven by the cover plate, reducing the thickness of the customizable switch. In particular, the circuit board has a first power mounting hole, and the switch base has a second power mounting hole. The first and second power mounting holes are opposite each other in the thickness direction of the customizable switch. The power cover and the power source are at least partially located within the first and second power mounting holes. The power cover and the second power mounting hole are detachable. The power cover and the power source share the thickness direction space with the switch base and the circuit board, meaning that the power cover and the power source occupy the thickness direction space of the switch base. This makes the customizable switch thinner, lighter, and more in line with current aesthetic needs and market trends.

[0021] In addition, the switch base also includes a bottom groove connected to the second power mounting hole, and the circuit board also includes a power clearance hole communicating with the first power mounting hole. The power clearance hole and the bottom groove are opposite to each other in the direction of the thickness of the switch. During installation, the power supply extends from the power clearance hole and is inserted laterally into the second power mounting hole. The bottom groove on the switch base further serves to avoid the power supply and facilitates the installation of the power supply.

[0022] In addition, a clearance groove is provided on the side of the cover plate facing the switch base. The clearance groove is opposite to the power source. When the cover plate swings, the clearance groove plays a role in avoiding the power source, which can further reduce the thickness and prevent the cover plate from accidentally touching the power source.

[0039] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0040] like Figures 1-7 As shown, the free-attach switch provided in this application includes a cover plate 1, a circuit board 2, and a switch base 3 stacked sequentially. The switch base 3 includes a base groove, and the circuit board 2 is installed in the base groove. The cover plate 1 and the switch base 3 are rotatably mounted. The circuit board 2 is electrically connected to a power supply 21, a wireless communication module (not shown in the figure), and at least one micro switch 22. The wireless communication module can receive and send commands, and can wirelessly control electrical equipment or other equipment by controlling the free-attach switch. The side of the cover plate 1 facing the circuit board 2 is provided with at least one driving part 11, and the at least one driving part 11 corresponds to and drives the at least one micro switch 22.

[0041] In particular, such as Figure 1 As shown, the free-attach switch also includes a power cover 23. The circuit board 2 has a first power mounting hole 24, and the switch base 3 has a second power mounting hole 25. The first power mounting hole 24 and the second power mounting hole 25 are opposite to each other in the thickness direction of the free-attach switch. The power cover 23 and the power supply 21 are at least partially located in the first power mounting hole 24 and the second power mounting hole 25. The power cover 23 and the second power mounting hole 25 are detachable, which facilitates the removal and replacement of the power supply 21.

[0042] Compared to existing technologies, the customizable switch of this application includes a cover plate, a circuit board, and a switch base stacked sequentially. The cover plate and the switch base are rotatably mounted without a pressure plate. The micro switch on the circuit board is directly driven by the cover plate, reducing the thickness of the customizable switch. In particular, the circuit board has a first power mounting hole, and the switch base has a second power mounting hole. The first and second power mounting holes are opposite each other in the thickness direction of the customizable switch. The power cover and the power source are at least partially located within the first and second power mounting holes. The power cover and the second power mounting hole are detachable. The power cover and the power source share the thickness direction space with the switch base and the circuit board, meaning that the power cover and the power source occupy the thickness direction space of the switch base. This makes the customizable switch thinner, lighter, and more in line with current aesthetic needs and market trends.

[0043] Furthermore, such as Figure 2 As shown, the power cover 23 includes a power mounting slot, and the power supply 21 is located inside the power mounting slot.

[0044] Furthermore, such as Figure 2 As shown, the side of the power cover 23 facing away from the cover plate 1 is flush with the side of the switch base 3 facing away from the cover plate 1, which reduces the groove between the power cover 23 and the switch base 3, prevents dust accumulation, and further improves the dustproof effect of the power supply 21. Moreover, the flush structure makes the power cover 23 more aesthetically pleasing after it is installed on the switch base 3. Alternatively, in a less desirable embodiment, the side of the power cover 23 facing away from the cover plate 1 is located inside the second power mounting hole 25 and is not flush with the side of the switch base 3 facing away from the cover plate 1, which is also acceptable.

[0045] Furthermore, such as Figure 1 , Figure 6 and Figure 7 As shown, the power cover 23 is snapped together with the switch base 3. The power cover 23 includes a covering surface 231. At least one first snap-fit ​​protrusion 232 is provided on the side of the covering surface 231 facing the cover plate 1. The first snap-fit ​​protrusion 232 includes a snap-fit ​​barb. At least one limiting rib 233 is provided on the side of the switch base 3 facing the cover plate 1. The power cover 23 is installed in the second power mounting hole 25 from the side of the switch base 3 facing away from the cover plate 1. At least one first snap-fit ​​protrusion 232 corresponds one-to-one with at least one limiting rib 233, and the snap-fit ​​barb abuts against the limiting rib 233. Figure 2 As shown, the length of the limiting rib 233 is greater than or equal to the thickness of the circuit board 2, so that the circuit board 2 is tightly attached to the base groove, and the thickness of the arbitrarily attached switch is reduced after installation.

[0046] Furthermore, the switch base 3 may not have the limiting rib 233, and the buckle barb may directly abut against the side of the switch base 3 facing the cover plate 1; or, the side wall of the second power mounting hole 25 may have at least one slot, and at least one first buckle protrusion 232 may correspond one-to-one with at least one slot, and the buckle barb may extend into the slot for buckle installation.

[0047] Furthermore, in another embodiment of the power cover 23 (not shown in the figure), the side of the covering surface 231 is provided with an installation structure and two first protrusions at intervals. The installation structure includes a second snap-fit ​​protrusion protruding from the covering surface 231. The two first protrusions extend from both sides of the covering surface 231. The side wall of the second power mounting hole 25 of the switch base 3 is provided with two first grooves. When the power cover 23 is installed in the second power mounting hole 25, the two first protrusions are correspondingly installed in the two first grooves. Pressing the power cover 23 causes it to plastically deform. The second snap-fit ​​protrusion extends into the side of the switch base 3 facing the cover plate 1. In a preferred embodiment, the side of the switch base 3 facing the cover plate 1 is provided with a limiting rib. The second snap-fit ​​protrusion and the limiting rib abut against each other along the thickness direction of the switch. The limiting rib enhances the plastic deformation effect of the power cover 23, making the power cover 23 more firmly installed.

[0048] Furthermore, such as Figure 6 and Figure 7 As shown in the preferred embodiment of this application, the covering surface 231 has a circular structure. A limiting rib 234 protrudes from the side of the covering surface 231 towards the switch base 3. The limiting rib 234 includes at least one limiting notch 235 spaced apart. The sidewall of the second power mounting hole 25 includes at least one limiting protrusion 236 spaced apart. The at least one limiting notch 235 and the at least one limiting protrusion 236 are installed in a one-to-one correspondence to restrict the axial rotation of the covering surface 231. Of course, it is also possible for the limiting rib 234 to include at least one limiting protrusion 236, and for the sidewall of the second power mounting hole 25 to include at least one limiting notch 235; this will not be elaborated further.

[0049] Furthermore, the side of the power cover 23 includes a first disassembly notch 237, or the side wall of the second power mounting hole 25 includes a second disassembly notch 238, or the side of the power cover 23 includes a first disassembly notch 237 and the side wall of the second power mounting hole 25 includes a second disassembly notch 238, the first disassembly notch 237 and the second disassembly notch 238 are opposite each other, and the first disassembly notch 237 and the second disassembly notch 238 are used to disassemble the power cover 23.

[0050] Furthermore, such as Figure 1 , Figure 3 and Figure 5As shown, the power supply 21 is a button battery, and the circuit board 2 includes a positive terminal connecting piece 241 and a negative terminal connecting piece 242 located in the first power supply mounting hole 24. The positive terminal connecting piece 241 is connected to the side wall of the power supply 21 (power supply positive 211), and the negative terminal connecting piece 242 is connected to the top surface of the power supply 2 (power supply negative 212).

[0051] Furthermore, such as Figure 5 and Figure 6 As shown, the switch base 3 also includes a bottom groove 311 connected to the second power mounting hole 25, and the circuit board 2 also includes a power clearance hole 243 communicating with the first power mounting hole 24. The power clearance hole 243 and the bottom groove 311 are opposite to each other in the direction of the thickness of the switch. During installation, the power supply 21 extends from the power clearance hole 243 and is inserted laterally into the second power mounting hole 25. The bottom groove 311 on the switch base 3 further serves to avoid the power supply 21, making it easier to install the power supply 21.

[0052] Preferred, such as Figure 4 As shown, at least one elastic element 12 is provided on the side of the cover plate 1 facing the circuit board 2 and / or at least one elastic element 12 is provided on the side of the switch base 3 facing the circuit board 2. The at least one elastic element 12 is driven to cooperate with the switch base 3 to drive the cover plate 1 to reset.

[0053] Preferred, such as Figure 3 and Figure 6 As shown, the base groove includes a circuit board mounting groove 312, and the circuit board 2 is installed in the circuit board mounting groove 312.

[0054] Furthermore, such as Figure 3 , Figure 5 and Figure 6 As shown, the circuit board 2 and the switch base 3 are riveted and fixedly installed. At least one hot-riveting post 32 is provided on the side of the circuit board mounting groove 312 facing the circuit board 2, and at least one hot-riveting hole 26 is provided on the circuit board 2. The at least one hot-riveting post 32 and the at least one hot-riveting hole 26 are fixed together by a hot-riveting process, ensuring a secure fixation.

[0055] In other embodiments, the circuit board 2 and the switch base 3 can also be fixed by clips or screws, which will not be described in detail here.

[0056] Furthermore, such as Figure 3 , Figure 5 and Figure 6As shown, the circuit board mounting slot 312 includes at least one mounting post 33, and the circuit board 2 includes at least one clearance notch 27. The at least one mounting post 33 and the at least one clearance notch 27 are in a one-to-one limiting fit to restrict the movement of the circuit board 2. In a preferred embodiment of this application, mounting posts 33 are provided on opposite sides of the circuit board mounting slot 312, and clearance notches 27 are provided on opposite sides of the circuit board 2. The two clearance notches 27 and the two mounting posts 33 are correspondingly installed to limit the movement of the circuit board 2. In a preferred embodiment of this application, the arbitrarily attached switch is fixedly connected to the outside (which may be a wall) by screws or rivets. The mounting post 33 includes a mounting hole, through which screws or rivets are passed to fix the arbitrarily attached switch to the outside. Furthermore, a silicone pad or a flip-up plate is provided inside the mounting hole to insulate or prevent dust from entering the mounting hole.

[0057] Furthermore, such as Figure 6 As shown, the circuit board mounting groove 312 includes a first side wall 34, a second side wall 35, a third side wall 36, and a fourth side wall 37 that limit the movement of the circuit board 2. The first side wall 34, the second side wall 35, the third side wall 36, and the fourth side wall 37 are connected in sequence to form a rectangular structure. The first side wall 34 and / or the second side wall 35 and / or the third side wall 36 and / or the fourth side wall 37 are provided with at least one third snap-fit ​​protrusion 38. The circuit board 2 is installed in the circuit board mounting groove 312, and at least one third snap-fit ​​protrusion 38 limits the movement of the circuit board 2 along the thickness direction of the switch and removes it from the circuit board mounting groove 312.

[0058] Furthermore, such as Figure 4 As shown, at least one first pressing rib 13 is provided on the side of the cover plate 1 facing the switch base 3. The at least one first pressing rib 13 is opposite to the first side wall 34 and / or the second side wall 35 and / or the third side wall 36 and / or the fourth side wall 37 along the thickness direction of the freely attachable switch. This ensures that when the freely attachable switch is operated, the first pressing rib 13 abuts against the first side wall 34 and / or the second side wall 35 and / or the third side wall 36 and / or the fourth side wall 37. Thus, the driving part 11 at the unpressed position of the cover plate 1 will not press against the corresponding micro switch 22 on the circuit board 2, avoiding malfunction. In a preferred embodiment of this application, two first pressing ribs 13 are provided on both sides of the rotation axis of the cover plate 1, and the two first pressing ribs 13 abut against the second side wall 35 and the fourth side wall 37, respectively.

[0059] Furthermore, such as Figure 4 As shown, the cover plate 1 is provided with a relief groove 14 on the side facing the switch base 3. The relief groove 14 is opposite to the power supply 21. When the cover plate 1 swings, the relief groove 14 plays the role of avoiding the power supply 21, which can further reduce the thickness and prevent the cover plate 1 from accidentally touching the power supply 21.

[0060] Furthermore, such as Figure 4 As shown, at least one second pressure rib 15 is provided on the side of the cover plate 1 facing the switch base 3. The second pressure rib 15 abuts against the circuit board 2, restricting the movement of the circuit board 2 along the thickness direction of the freely attachable switch. In a preferred embodiment of this application, the cover plate 1 includes two second pressure ribs 15, and the two second pressure ribs 15 are located in the clearance groove 14, with their projections in the thickness direction of the freely attachable switch located on both sides of the power supply 21.

[0061] Preferred, such as Figure 3 and Figure 4 As shown, the cover plate 1 and the switch base 3 are rotatably connected by a snap-fit ​​mechanism. The side of the cover plate 1 facing the switch has at least one first snap-fit ​​29, which includes two snap-fit ​​arms with a snap-fit ​​groove between them. The switch base 3 has at least one snap-fit ​​shaft 39 corresponding to the first snap-fit ​​29. The snap-fit ​​shaft 39 is installed in the snap-fit ​​groove, and the two snap-fit ​​arms clamp the snap-fit ​​shaft 39, allowing the cover plate 1 and the switch base 3 to be rotatably fixed by the snap-fit ​​structure. The rotation axis of the cover plate 1 is located on the plane of the switch base 3, or the rotation axis of the cover plate 1 is located inside the switch base 3. Lowering the position of the rotation axis of the cover plate 1 reduces the gap between the cover plate 1 and the switch base 3, thereby reducing the thickness of the arbitrarily attached switch.

[0062] Furthermore, such as Figure 3 and Figure 4 As shown, the cover plate 1 has two first latches 29 on both sides of the side facing the switch base 3, and two retaining shafts 39 are provided on the opposite sides of the mounting post 33. The two retaining shafts 39 are located inside the base groove and outside the circuit board mounting groove 312. In a preferred embodiment of this application, the two retaining shafts 39 and the two mounting holes are located on the same straight line.

[0063] Preferred, such as Figure 1 , Figure 3 and Figure 4 As shown, the circuit board 2 has at least one light-emitting element 28 on the side facing the cover plate 1. The light-emitting element 28 can be, but is not limited to, an LED light. The cover plate 1 has at least one display window 16, which can be a through-hole structure or a transparent closed structure. The light source of the at least one light-emitting element 28 is transmitted to the outside of the arbitrarily attached switch through the at least one display window 16. When the micro switch 22 is triggered, the light-emitting element 28 lights up, and the display window 16 can be used to indicate to the outside that it is working. Preferably, at least one display window 16 and at least one light-emitting element 28 correspond one-to-one, resulting in better light transmission.

[0064] Furthermore, such as Figure 4As shown, at least one arc-shaped focusing groove 17 is provided on the side of the cover plate 1 facing the switch base 3. The area of ​​the outer diameter of the arc-shaped focusing groove 17 is larger than the area of ​​the bottom of the arc-shaped focusing groove. At least one display window 16 is respectively disposed at the bottom of at least one arc-shaped focusing groove 17. The arc-shaped focusing groove 17 can produce a focusing effect, making the display effect of the display window 16 better. In a preferred embodiment of this application, the cover plate 1 includes four display windows 16 and four arc-shaped focusing grooves 17 located at the four corners of the cover plate 1.

[0065] Preferred, such as Figure 3 and Figure 4 As shown, four micro switches 22 are provided at the four corners of the circuit board 2, and four driving parts 11 for driving the four micro switches 22 and four elastic elements 12 for driving the cover plate 1 to reset are provided at the four corners of the cover plate 1.

[0066] Furthermore, such as Figure 4 As shown, the elastic element 12 has an "L"-shaped structure, including a first bent portion and a second bent portion connected by bending. The first bent portion is perpendicular to the plane of the cover plate 1, and the second bent portion is parallel to the plane of the cover plate 1. An elastic protrusion is provided at the end of the second bent portion away from the first bent portion, facing the switch base 3. The elastic protrusion is driven and engaged with the switch base 3. The elastic element 12 can be integrally formed with the cover plate 1 or fixedly connected. The elastic element 12 can be made of elastic plastic or metal. When the elastic element 12 is made of plastic, it can drive the cover plate 1 to reset after plastic deformation and energy storage. Alternatively, in other embodiments, the elastic element 12 can also be a spring, compression spring, torsion spring, tension spring, or elastic silicone element disposed on the cover plate 1 and / or the switch base 3, which will not be elaborated further.
