Description

Technical Field

[0001] This invention relates to the field of wall switch technology, and more particularly to a smart home touch-controlled wall switch. Background Technology

[0002] Many devices can be installed on the walls of a building. Wall switches are devices installed on the walls to control circuits. Smart wall switches are one type of wall switch. The internal components of a wall switch include a circuit board and many accessories, enabling network-connected smart control of the circuit. It also allows for touch screen input of commands to control the circuit. When the moving contact and the fixed contact of a smart wall switch are in contact, the circuit is connected; when the moving contact and the fixed contact are separated, the circuit is disconnected.

[0003] In existing wall switches, the moving contact is typically located on a component that can move within a certain range. The moving contact is moved by the moving component to separate or make contact with the fixed contact. The moving component needs to be limited by many components, making the structure very complex, prone to errors, and lacking in foolproof capability. Furthermore, the moving component needs to be driven by a spring-loaded component to ensure stable contact between the moving and fixed contacts. After prolonged use, the spring force weakens, leading to poor contact between the moving and fixed contacts, affecting the stability of the wiring. Its lifespan is limited by the lifespan of the spring-loaded component, making it very inconvenient to use. Therefore, there is a need to provide a smart home touch wall switch that uses gravity to drive the driven contact to overcome the above defects. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where the moving contact is set on a component that can move within a certain range. The moving contact is moved by the moving component to achieve separation or contact between the moving contact and the fixed contact. The moving component needs to be limited by many components, which makes the structure very complex, prone to errors, and lacks foolproof capability. In addition, the moving component needs to be driven by a spring component to ensure stable contact between the moving contact and the fixed contact. After long-term use, the elasticity of the spring component weakens, resulting in poor contact between the moving contact and the fixed contact, affecting the stability of the wiring. Its service life is limited by the service life of the spring component, which is very inconvenient to use. Therefore, this invention proposes a smart home touch wall switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart home touch wall switch, comprising a mounting shell and an integrally formed mounting flange, a mounting cover detachably snapped onto the mounting flange, a touch screen embedded in the center of the mounting cover, a circuit board on the inner wall of the mounting shell, a wiring shell embedded in the mounting shell, a fixing bolt threaded into the side of the wiring shell, a servo motor fixed to the inner wall of the mounting shell by a support rod, a plastic disc on the power output end at the bottom of the servo motor, multiple connecting plates embedded in the side of the plastic disc, and rotating parts on the connecting plates for connecting or disconnecting the current circuit; two metal boxes on the inner wall of the mounting shell, a metal disc movably connected to the inner wall of the metal boxes, the metal disc pressing against the rotating parts and the inner wall of the metal boxes by its own weight for connecting or disconnecting the current circuit.

[0006] More preferably, the rotating component has multiple adhesive grooves to form channels for injecting adhesive, and the adhesive grooves are semi-circular.

[0007] More preferably, the rotating component is a ring formed by splicing two plastic plates and two metal plates. One end of each of the two plastic plates and two metal plates is integrally formed with a male tenon strip, and the other end of each of the two plastic plates and two metal plates is provided with a female tenon groove to match the male tenon strip.

[0008] More preferably, the adhesive groove is located on the tenon strip of the metal plate and the plastic plate, and an insertion groove is provided in the middle of the inner side of the metal plate and the plastic plate, and the adhesive groove is located in the insertion groove.

[0009] More preferably, the rotating component is a metal ring and an insulating plate, wherein the surface of the metal ring is embedded with an area formed by the insulating plate on the surface of the metal ring to cut off the current loop, and the curvature of the insulating plate is 140°-180°.

[0010] More preferably, the adhesive groove is located in the gap between the metal ring and the insulating plate, and the channel formed by the two adhesive grooves is located between the metal ring and the insulating plate.

[0011] More preferably, the connecting plate surrounds the inner side of the rotating component and between the plastic disc, and the included angle formed by the two metal boxes is less than 140°.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1:

[0028] Reference Figure 1-7 A smart home touch wall switch includes a mounting shell 1 and an integrated mounting flange 3. A mounting cover 4 is detachably snapped onto the mounting flange 3. A touch screen 9 is embedded in the center of the mounting cover 4. A circuit board 5 is provided on the inner wall of the mounting shell 1. A wiring shell 2 is embedded in the mounting shell 1. A fixing bolt 10 is threaded into the side of the wiring shell 2. A servo motor 6 is fixed to the inner wall of the mounting shell 1 by a support rod. A plastic disc 11 is provided on the power output end at the bottom of the servo motor 6. Multiple connecting plates 12 are embedded in the side of the plastic disc 11. A rotating part is provided on the connecting plate 12 for connecting or disconnecting the current circuit. Two metal boxes 15 are provided on the inner wall of the mounting shell 1. A metal disc 16 is movably connected to the inner wall of the metal box 15. The metal disc 16 presses against the rotating part and the inner wall of the metal box 15 by its own weight to connect or disconnect the current circuit.

[0029] Preferably, the rotating part is a ring spliced ​​together by two plastic plates 13 and two metal plates 14. One end of each of the two plastic plates 13 and two metal plates 14 is integrally formed with a male tenon strip, and the other end of each of the two plastic plates 13 and two metal plates 14 is provided with a female tenon groove to match the male tenon strip.

[0030] In practice, two plastic plates 13 are spliced ​​together, and two metal plates 14 are spliced ​​together. Then, the two ends of the two plastic plates 13 and the two metal plates 14 are spliced ​​together, dividing the surface area of ​​the rotating part into two parts. The plastic plates 13 form an insulating area on the rotating part to disconnect the current, and the metal plates 14 form a conductive area on the rotating part to connect the current. The two plastic plates 13 and the two metal plates 14 rotate simultaneously, rotating the plastic plates 13 and the metal plates 14 to be directly below the two metal disks 16. The two metal disks 16 abut against the two plastic plates 13 or the two metal plates 14, which can serve to disconnect or connect the current.

[0031] Preferably, multiple adhesive grooves 17 are provided in the rotating part to form channels for injecting glue. The adhesive grooves 17 are semi-circular and are located on the male tenon strips of the metal plate 14 and the plastic plate 13. An insertion groove is provided in the middle of the inner side of the metal plate 14 and the plastic plate 13. The adhesive grooves 17 are located in the insertion grooves. After the metal plate 14 and the plastic plate 13 are spliced ​​by the male tenon strips and the female tenon grooves, the glue is injected into the channel formed by the adhesive grooves 17. After the glue solidifies, it firmly bonds the metal plate 14 and the plastic plate 13 together, which facilitates the assembly of the metal plate 14 and the plastic plate 13.

[0032] Preferably, the surface of the metal disc 16 is tangent to both the inner wall of the metal box 15 and the rotating component. The thickness of the metal disc 16 is consistent with the thickness of the rotating component. The connecting plate 12 surrounds the inner side of the rotating component and the plastic disc 11. The included angle formed by the two metal boxes 15 is less than 140°. The metal box 15 is kept tilted so that its inner wall is tilted, causing the metal disc 16 to move downward along the inner wall of the metal box 15. The metal disc 16 abuts against the inner wall of the metal box 15 and the rotating component respectively, using gravity to connect or disconnect the circuit.

[0033] Preferably, the mounting flange 3 has screw holes 8, the circuit board 5 is equipped with a central processing unit 7, a transformer, a relay, a control switch, a storage module and other matching electronic components, the two wiring shells 2 and the two metal boxes 15 are connected in series in the circuit to be controlled by wires, the circuit board 5 is connected in parallel to one of the wiring shells 2 by wires, and the touch screen 9 and the servo motor 6 are electrically connected to the circuit board 5 by wires.

[0034] In practical implementation, the terminal shell 2 connected in parallel with the circuit board 5 is connected to the live wire of the required control circuit, so that the circuit board 5 is connected in parallel in the circuit. Regardless of whether the required control circuit is connected or not, current can be supplied to the circuit board 5. When the two terminal shells 2 and the two metal boxes 15 form a current loop, the circuit is connected. When the two terminal shells 2 and the two metal boxes 15 cannot form a current loop, the current can only flow to one of the terminal shells 2 and the circuit board 5. Whether the terminal shells 2 and the two metal boxes 15 can form a current loop depends on the two metal discs 16 pressing against the two metal plates 14 or plastic plates 13. Commands can be input through the touch screen. The central processing unit controls the operation of the servo motor 6 according to the commands. The servo motor 6 drives the two metal plates 14 and plastic plates 13 to rotate 180 degrees, changing the contact area between the two metal discs 16 and the rotating parts, thereby controlling the opening and closing of the circuit.

[0035] The metal disk 16 must be circular. This ensures that the center of gravity of the metal disk 16 remains constant during rotation, reducing friction between the metal disk 16 and the rotating component, and minimizing resistance to the rotation of the metal disk 16. Furthermore, it divides the weight of the metal disk 16 into two forces: one perpendicular to the inner wall of the metal box 15, and the other perpendicular to the center of the rotating component. This ensures that the metal disk 16 is always tangent to both the metal box 15 and the rotating component, and the force perpendicular to the center of the rotating component will not cause it to rotate, thus reducing the resistance to the rotation of the rotating component. It also prevents the rotating component from being rotated by a force tangential to its surface when stationary, ensuring the stability of the rotating component when stationary, thereby ensuring the stability of the wiring. The metal disk 16 cannot be an equilateral polygon or an ellipse. An equilateral polygon would hinder the rotation of the rotating component, and an elliptical metal disk 16 would have a changed center of gravity. Neither equilateral polygons nor ellipses are as stable as a metal disk 16 with a circular center.

[0036] Example 2:

[0037] Reference Figure 8-10 The difference from Embodiment 1 is that the rotating component is a metal ring 18 and an insulating plate 19. The surface of the metal ring 18 is embedded with an insulating plate 19, which forms a region on the surface of the metal ring 18 that cuts off the current circuit. The curvature of the insulating plate 19 is 140°-180°, and the curvature of the insulating plate 19 can be 140°, 150°, 160°, 170°, or 180°. Multiple adhesive grooves 17 are formed in the rotating component to form channels for injecting adhesive. The adhesive grooves 17 are semi-circular and are located in the gap between the metal ring 18 and the insulating plate 19. The channel formed by two adhesive grooves 17 is located between the metal ring 18 and the insulating plate 19.

[0038] In practice, grooves are cut into the surface of the metal ring 18, and the insulating plate 19 is inserted into the grooves of the metal ring 18. Then, glue is injected into the bonding groove 17, and the glue sticks the insulating plate 19 and the metal ring 18 together. The insulating plate 19 covers half of the surface of the metal ring 18 to form an insulating area, and the other half of the metal ring 18 is a conductive area. When the servo motor 6 drives the metal ring 18 and the insulating plate 19 to rotate synchronously, the area under the two metal discs 16 is changed, which can connect or disconnect the power supply in the circuit.

[0039] The fixing bolt 10 rotates on the wiring housing 2 by rotating a screwdriver, and the fixing bolt 10 presses the wires in the circuit, and the fixing bolt 10 can be used for wiring.

[0040] Among them, the plastic disk 11 is made of insulating material, which isolates the servo motor 6 from the current in the circuit and can protect the servo motor 6.

[0041] The connecting plate 12 is inserted into the groove of the plastic disc 11 and the rotating part, and then glued together. This allows the connecting plate 12, the plastic disc 11 and the rotating part to be assembled very quickly, which is convenient for the manufacture of the switch.

[0042] The screw hole 8 is used to mount the mounting shell 1 to the wall using bolts.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
