Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a zero-crossing detection type single-wire fan and light control device. Background Technology

[0002] Zero-crossing detection single-wire fan and light control devices are specialized control components adapted to traditional single-wire wiring scenarios. Alternating current exhibits a sinusoidal, periodic variation; zero-crossing detection technology accurately identifies the voltage zero-crossing point. The control device then triggers a switch action at this stable moment, achieving fan speed adjustment and light control. It requires no additional neutral wire and can directly connect to existing indoor wiring. Widely used in fan and light systems in homes, offices, and other locations, it balances ease of installation with smooth control, representing a practical upgrade to traditional fan and light control solutions.

[0003] Utility model patent CN217270951U discloses a Bluetooth rhythmic fan light. This Bluetooth rhythmic fan light includes a main body with a handle. A fixing mechanism is movably mounted on the upper end of the main body, and a lamp mounting mechanism is movably connected to the lower end. This Bluetooth rhythmic fan light utilizes the combined action of blades, a Bluetooth lamp, a speaker, a motor, a lamp fixing block, and a safety cable. Through the cooperation of the motor and safety cable, the motor operates quietly and powerfully while maintaining stable low-noise operation, creating a comfortable environment. Simultaneously, screws two and three are used to install the blades, achieving the coexistence of fan, lamp, and Bluetooth rhythmic functions. This solves the problem of using a single transmitter to control two receivers simultaneously, improving the device's practicality and versatility.

[0004] The control components of this Bluetooth rhythmic fan light are fixedly connected to the main body of the fan light. The internal circuitry of the control components is integrated and fixedly installed using rigid connectors such as screws. When the control components malfunction and require repair, multiple fixed connectors must be disassembled one by one to remove the control components from the main body of the fan light, making the disassembly and assembly process cumbersome. At the same time, the integrated internal circuitry means that if a local fault occurs, the entire control components must be replaced, resulting in poor maintenance flexibility. Furthermore, the disassembly and assembly process can easily interfere with other installation structures of the fan light. In view of this, we propose a zero-detection single-wire fan light control device. Summary of the Invention

[0005] The purpose of this invention is to provide a zero-crossing detection type single-wire fan light control device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A zero-crossing detection type single-wire fan light control device includes a lamp body. The lamp body is equipped with a control component that is connected to an external power supply via a single live wire. The control component includes a fixed base fixed to the lamp body, a plug-in socket detachably installed in the fixed base, and several circuit boards plugged into the plug-in socket.

An end plate is provided at the outer end of the plug-in socket, and a male connector is provided at the inner end of the plug-in socket. The male connector can be inserted into the female connector and electrically connected to the female connector.

[0008] The socket is provided with several mounting bases for mounting circuit boards. The mounting bases have slots. The circuit board, the mounting bases and the connector are electrically connected.

[0009] A locking assembly is provided on the top surface of the fixed base. The locking assembly includes a base fixed to the top of the fixed base and a locking block slidably connected in the base. A protrusion is provided at the outer end of the top of the base. A spring is provided between the tail of the locking block and the protrusion. Hinges are hinged to both ends of the end plate. A crossbar is fixed between the ends of the two hingees. A stop groove is provided at the head of the locking block. The crossbar can be inserted into the stop groove by moving the hinge.

[0010] Preferably, the top of the lamp body is provided with a lamp holder, the top of the lamp holder is fixed with a lamp rod, and the adjustment component is fixed on the outer surface of the lamp holder;

[0011] This setting makes the installation position of the control component more reasonable and facilitates connection with the power supply line of the lamp body;

[0012] Preferably, the top of the plug-in socket has a notch, the left and right ends of the notch are open, and the bottom surface of the notch has a bottom cavity. Several partitions are fixed in the bottom cavity, and the multiple partitions divide the bottom cavity into multiple mounting cavities. Several mounting seats are installed in each mounting cavity respectively.

[0013] This setting enables partitioned installation of the mounting base, improving the utilization of the internal space of the connector;

[0014] Preferably, the mounting cavity has slots on both the left and right sides of the cavity wall, and a buckle plate is attached between the two slots. The buckle plate has claws at both ends, and a block is attached at the outer edge of the bottom of the claw. By inserting the buckle plate into the mounting cavity, the blocks on the two claws can be inserted into the two slots on the same mounting cavity respectively.

[0015] This design ensures a secure connection between the buckle plate and the mounting cavity, providing a foundation for fixing the circuit board.

[0016] Preferably, the bottom surface of the buckle plate is provided with a positioning groove, and when the buckle plate is installed into the corresponding mounting cavity, the top of the circuit board is inserted into the positioning groove;

[0017] This setting positions the top of the circuit board to enhance the stability of the circuit board installation;

[0018] Preferably, both ends of the end plate are provided with protruding convex shafts, and the first ends of the two hinge rods are sleeved on the outside of the convex shafts and rotatably connected to the convex shafts. The hinge rods are hinged to the end plate through the convex shafts.

[0019] This setting enables flexible hinge connection between the hinge rod and the end plate, ensuring smooth hinge rod operation;

[0020] Preferably, the base has a rectangular frame structure, the locking block is fitted inside the base, and sliding grooves are provided at the bottom edges of both the left and right sides inside the base. The bottom edges of the locking block are provided with protruding edges, and the two protruding edges extend into the two sliding grooves respectively.

[0021] This setting ensures the locking block slides smoothly within the base, preventing deviation during the sliding process;

[0022] Preferably, a countersunk hole is provided on the end face of the protrusion near the locking block, and a concave hole is provided on the tail end face of the locking block corresponding to the position of the countersunk hole. The spring is sleeved between the countersunk hole and the concave hole, with the first end of the spring abutting against the bottom of the countersunk hole and the last end of the spring abutting against the bottom of the concave hole, and the spring is in a compressed state.

[0023] In this setting, the spring is limited and fixed to ensure that the spring applies a stable elastic force to the locking block;

[0024] Preferably, the locking block has a protruding post at its tail end, which is fixed at the center of the bottom of the concave hole. The end of the protruding post passes through the inside of the spring, the sleeve hole, and the protruding seat in sequence, and the protruding post and the protruding seat are slidably connected.

[0025] This setting further guides the sliding of the locking block, enhancing the stability of the locking block's movement;

[0026] Preferably, the bottom of the stop groove is arc-shaped, the length direction of the stop groove is parallel to the axial direction of the crossbar, and the opening of the sliding groove faces away from the plug seat. Under the action of the spring force, the locking block always applies a pushing force to the crossbar in the direction away from the plug seat.

[0027] This setting ensures a tight fit between the crossbar and the stop groove, enhancing the locking effect of the locking assembly.

In case of local failure, only the corresponding circuit board needs to be removed for repair or replacement, which improves maintenance flexibility.

[0031] 3. This zero-crossing detection single-wire fan light control device, through the sliding cooperation between the plug and the fixed seat and the locking mechanism of the locking component, ensures that the disassembly and assembly process will not interfere with other components of the fan light.

[0046] Example 1

[0047] Please see Figures 1-7 A zero-crossing detection type single-wire fan light control device includes a lamp body 100, a lamp holder 110 at the top of the lamp body 100, a lamp post 120 fixed at the top of the lamp holder 110, and a control component 200 connected to an external power supply via a single live wire on the lamp body 100. The control component 200 is fixed on the outer surface of the lamp holder 110. This installation position facilitates the connection between the control component 200 and the internal power supply line of the lamp body 100, and also facilitates later maintenance operations. The control component 200 includes a mounting base 210 fixed on the lamp body 100, a plug-in socket 220 detachably installed in the mounting base 210, and several circuit boards 230 plugged into the plug-in socket 220. The mounting base 210 provides a positioning and installation foundation for the plug-in socket 220, and the plug-in socket 220 enables centralized support and quick assembly / disassembly of the circuit boards 230.

[0048] like Figure 1 , Figure 2 and Figure 6 As shown, in this invention, a cavity 211 is provided on the outer end face of the fixing base 210. The cavity 211 provides a precise insertion guide for the plug-in base 220. A connecting female base 2111 is provided at the bottom of the cavity 211, and the plug-in base 220 is slidably inserted into the cavity 211. An end plate 2201 is provided at the outer end of the plug-in base 220, which serves to close the port of the plug-in base 220. A connecting male base 2202 is provided at the inner end of the plug-in base 220, which can be inserted into the connecting female base 2111 and electrically connected to the connecting female base 2111. This plug-in connection method does not require additional wiring operations and can quickly achieve electrical conduction between the circuit board 230 and the external power supply.

[0049] like Figures 4-6 As shown, specifically, the connector 220 is provided with several mounting bases 221 for mounting circuit boards 230. Each mounting base 221 has a slot 2211, the size of which is adapted to the thickness of the circuit board 230, ensuring tight contact after insertion. The circuit board 230, mounting base 221, and connector 2202 are electrically connected. A notch is provided at the top of the connector 220, with both ends being open, facilitating manual handling of the circuit board 230 for assembly and disassembly. A bottom cavity is formed at the bottom of the notch, containing several partitions 2203 that divide the cavity into multiple mounting chambers 2204. The partitions 2203 are made of insulating material to prevent electromagnetic interference or physical collisions between circuit boards 230 in adjacent mounting chambers 2204. The mounting bases 221 are respectively installed in each mounting chamber 2204.

[0050] like Figures 4-7As shown, furthermore, slots 2205 are provided on both the left and right sides of the mounting cavity 2204, and a buckle plate 222 is attached between the two slots 2205. Both ends of the buckle plate 222 are provided with claws 2221, which have a certain elastic deformation capability, facilitating the insertion or removal of the locking blocks 2222 from the slots 2205. Locking blocks 2222 are provided at the outer edges of the bottom ends of the claws 2221. By inserting the buckle plate 222 into the mounting cavity 2204, the locking blocks 2222 on the two claws 2221 can extend into the two slots 2205 on the same mounting cavity 2204. The engagement of the locking blocks 2222 with the slots 2205 securely fixes the buckle plate 222, preventing it from accidentally falling off. The bottom surface of the buckle 222 is provided with a positioning groove 2223. When the buckle 222 is installed into the corresponding mounting cavity 2204, the top of the circuit board 230 is inserted into the positioning groove 2223. The positioning groove 2223 and the slot 2211 cooperate to form vertical positioning, which restricts the longitudinal displacement of the circuit board 230 and improves the stability of the circuit board 230 after installation.

[0051] In this embodiment, the zero-crossing detection type single-wire fan light control device is used as follows: First, the circuit boards 230 corresponding to each function are inserted into the slots 2211 of the mounting base 221 in the plug-in socket 220 to ensure that the circuit boards 230 and the mounting base 221 are electrically connected. Then, the buckle plate 222 is aligned with the mounting cavity 2204 and inserted, so that the locking block 2222 on the claw 2221 is locked into the slot 2205, and the top of the circuit board 230 is simultaneously inserted into the positioning slot 2223 to complete the fixation. Next, the plug-in socket 220 is aligned with the cavity 211 of the fixing base 210 and slowly pushed in by holding the end plate 2201 until the male connector 2202 is fully inserted into the female connector 2111 to achieve electrical conduction. Finally, after confirming that the plug-in socket 220 is installed in place, the single-wire power supply control of the fan light can be realized through the control component 200.

[0052] Example 2

[0053] like Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, a locking component 240 is provided at the top surface of the fixed base 210. The locking component 240 is used to lock the plug-in socket 220 to the fixed base 210 to prevent the plug-in socket 220 from loosening due to vibration during the operation of the fan light. The locking component 240 includes a base 241 fixed to the top of the fixed base 210 and a locking block 242 slidably connected in the base 241. The base 241 provides installation and sliding space for the locking block 242. A boss 2412 is provided at the top outer end of the base 241, providing a fixed support point for the spring 2425. A spring 2425 is installed between the tail of the locking block 242 and the boss 2412, providing a continuous elastic thrust to the locking block 242. Hinges 2207 are provided at both ends of the end plate 2201, and protruding shafts 2206 are provided at both ends of the end plate 2201, providing rotation fulcrums for the hinges 2207 to ensure flexible rotation of the hinges 2207. The two hinges... The first end of the rod 2207 is sleeved on the outside of the convex shaft 2206 and rotatably connected to the convex shaft 2206. The hinge rod 2207 is hinged to the end plate 2201 through the convex shaft 2206. A crossbar 2208 is fixed between the ends of the two hinge rods 2207. The crossbar 2208 serves as the locking force point of the locking block 242. A stop groove 2422 is provided at the first end of the locking block 242. The stop groove 2422 is adapted to the crossbar 2208 to achieve precise engagement. By moving the hinge rod 2207, the crossbar 2208 can be sleeved into the stop groove 2422.

[0054] In this embodiment, the base 241 has a rectangular frame structure, and the locking block 242 is fitted inside the base 241. Sliding grooves 2411 are provided at the bottom edges of both the left and right sides inside the base 241, and protruding edges 2421 are provided at the bottom edges of both the left and right sides of the locking block 242. The two protruding edges 2421 extend into the two sliding grooves 2411 respectively, and the protruding edges 2421 slide in conjunction with the sliding grooves 2411, restricting the vertical displacement of the locking block 242 and ensuring that the locking block 242 slides smoothly in the horizontal direction.

[0055] Specifically, a countersunk hole 2413 is provided on the end face of the boss 2412 near the locking block 242, and a recessed hole 2423 is provided on the tail end face of the locking block 242 corresponding to the position of the countersunk hole 2413. The spring 2425 is sleeved between the countersunk hole 2413 and the recessed hole 2423. The countersunk hole 2413 and the recessed hole 2423 limit the two ends of the spring 2425 to prevent the spring 2425 from shifting or falling off during the extension and retraction process. The first end of the spring 2425 abuts against the bottom of the countersunk hole 2413 and the last end abuts against the bottom of the recessed hole 2423. The spring 2425 is in a compressed state.

[0056] Furthermore, the locking block 242 has a protrusion 2424 at its tail end. The protrusion 2424 is fixed at the center of the bottom of the concave hole 2423. The end of the protrusion 2424 passes through the inside of the spring 2425, the sleeve hole 2413 and the boss 2412 in sequence. The protrusion 2424 and the boss 2412 are slidably connected. The protrusion 2424 further provides guidance for the sliding of the locking block 242, ensuring the accurate movement trajectory of the locking block 242, and at the same time enhancing the structural stability of the locking block 242.

[0057] In addition, the bottom of the stop groove 2422 is arc-shaped, which reduces the friction between the crossbar 2208 and the stop groove 2422, making it easier for the crossbar 2208 to fit in and out. The length direction of the stop groove 2422 is parallel to the axial direction of the crossbar 2208, and the opening of the sliding groove 2411 faces away from the insertion seat 220. Under the action of the spring 2425, the locking block 242 always applies a pushing force to the crossbar 2208 in the direction away from the insertion seat 220. This pushing force makes the crossbar 2208 fit tightly with the bottom of the stop groove 2422, improving the reliability of the locking structure and preventing loosening.

[0058] In this embodiment, when the zero-crossing detection type single-wire fan light control device needs to lock the plug-in socket 220, the hinge rod 2207 is rotated around the convex shaft 2206, causing the crossbar 2208 to move to the stop groove 2422. After releasing the hinge rod 2207, under the elastic thrust of the spring 2425, the locking block 242 slides along the sliding groove 2411, and the stop groove 2422 fits onto the outside of the crossbar 2208 to complete the locking. When unlocking is required, the hinge rod 2207 is reversed, pushing the locking block 242 to compress the spring 2425 and slide backward until the crossbar 2208 disengages from the stop groove 2422. At this time, the plug-in socket 220 can be pulled out from the sleeve cavity 211 of the fixed seat 210. The entire locking and unlocking process is simple to operate and the locking effect is stable.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
