Description

Technical Field

[0001] The invention relates to a switch control system, in particular to an intelligent switch. Background Art

[0002] The intelligent switch control system is an electrical switch device based on electronic technology and intelligent control technology, which is used to control the opening and closing of electrical equipment. Compared with traditional mechanical switches, it has higher intelligence, remote control and automation functions.

[0003] Existing smart switch control systems generally use mobile phone applications, the Internet or wireless communication modules to achieve intelligent opening and closing of switches. In the smart switch control system, a microcontroller is generally required as a processor to process and feedback the information sent remotely, thereby controlling the switch to open or close.

[0004] In actual use, intelligent switch control systems often fail, and the main reason is generally unstable voltage, which causes the microcontroller to cause its power supply voltage to fluctuate when processing information, affecting its working performance and information processing effect. The reason for the unstable voltage may be periodic fluctuations in the external AC power supply or because the intelligent switch generates heat when in use, affecting the resistivity of its internal components when the temperature rises, etc. Summary of the invention

[0005] The purpose of the present application is to provide an intelligent switch that can ensure good heat dissipation during use and reduce the impact of temperature on a microcontroller.

When the lever is moved to close the intelligent switch, the extension strip enters into the gap between the lever and the matching slot to close the gap, thereby preventing external dust or water vapor from entering the connecting seat and the electric control box.

[0008] The present invention is further configured as follows: the sealing plate is provided with a plurality of metal heat sinks arranged in sequence, the metal heat sinks are interconnected with the sealing plate, and the metal heat sinks are hollow structures made of metal with good thermal conductivity.

[0009] The present invention is further configured such that when the intelligent switch is placed vertically and installed at a wall switch installation position, liquid water enters into a plurality of metal heat sinks through a water pipe, so that heat absorbed by the liquid water can be quickly dissipated through the metal heat sinks.

[0010] In summary, the present invention has the following beneficial effects: the intelligent switch control system can maintain a stable voltage state for the microcontroller when the external power supply is unstable or fluctuating, thereby ensuring the working performance and information processing effect of the microcontroller. The intelligent switch applies the above-mentioned intelligent switch control system, and can ensure that it has a good heat dissipation effect during use, reducing the impact of temperature on the microcontroller.

[0034] like Figure 2 As shown, in order to solve the technical purpose of converting alternating current (AC) into more stable direct current (DC).

[0035] The power conversion module of the present application is composed of the following circuit elements:

[0036] AC input (Traveler A, Traveler B):

[0037] Traveler A and Traveler B are the input terminals of AC power, which are usually connected to the live wire and neutral wire of the AC power supply.

[0038] Fuse resistor (FR1, FR2):

[0039] FR1 and FR2 are fuse resistors with a value of 10Ω / 1W, which are used for overcurrent protection. When the current is too large, these resistors will fuse to protect the subsequent circuits.

[0061] Protection diodes (D1-ES1J, D2):

[0062] D1 and D2 are used to protect the circuit from reverse voltage causing damage to circuit components.

[0063] Resistors (R1, R2):

[0066] The working principle of the above power conversion module is as follows:

[0067] 1. AC input and rectification:

[0068] The AC power is input through Traveler A and Traveler B, passes through fuse resistors FR1 and FR2, enters rectifier bridge DB1, and outputs pulsating direct current (DC).

[0069] 2. Filtering:

[0070] The pulsating DC is smoothed by filter capacitors C1 and C2 to reduce high-frequency noise and obtain smooth DC.

[0071] 3.AC-DC conversion:

[0072] The smoothed DC enters the BP2525 chip (U1) and is converted into a stable 5V DC.

[0073] 4. Further filtering and voltage stabilization:

[0074] The 5V DC power is further processed by inductor L2 and filter capacitor C4 to ensure stable output voltage.

[0075] 5. Protection circuit:

[0076] In the power supply line, the varistor MOV1 absorbs overvoltage spikes to protect the circuit.

[0077] Diodes D1 and D2 protect circuit components from reverse voltage damage.

[0078] The power conversion module converts AC power into DC power and provides a relatively stable 5V DC power supply through multi-stage filtering and voltage stabilization to ensure the stability and safety of the circuit.

[0079] like Figure 3 As shown, in order to solve the technical problem of converting a relatively stable 5V DC into a regulated 3.3V DC of.

[0080] The voltage stabilizing and regulating module of the present application mainly includes the following components:

[0081] LDO regulator (U4-BL1117):

[0082] BL1117 is a low dropout linear regulator (LDO) used to regulate the input voltage to a lower output voltage.

[0083] Key pins:

[0084] 1(GND): Ground pin.

[0085] 2 (VOUT): Output voltage pin, providing a stable 3.3V output.

[0086] 3 (VIN): Input voltage pin, connected to 5V power supply.

[0087] 4 (VOUT): Output voltage pin, provides a stable 3.3V output (same as pin 2).

[0088] Filter capacitors (C7, C8):

[0089] C7 is a 0.1μF / 16V capacitor used for high frequency filtering and smoothing the output voltage.

[0090] C8 is a 10μF / 10V capacitor used to further smooth and stabilize the output voltage to ensure a stable output voltage.

[0091] The working process of the above voltage regulation and stabilization module is as follows:

[0092] 1. Input voltage (VIN):

[0093] The input voltage is 5V and is connected to the VIN pin (pin 3) of the BL1117 regulator.

[0094] 2. Voltage stabilization process

[0095] BL1117 regulates the input 5V voltage to 3.3V output. The chip has a low voltage dropout characteristic and can normally regulate the voltage when the input voltage is slightly higher than the output voltage. The regulated 3.3V DC is output to the VOUT pin (pin 2 and pin 4).

[0096] 3. Output voltage (VOUT):

[0097] The regulated 3.3V voltage is output through the VOUT pin and supplied to the subsequent circuits.

[0098] 4. Filter capacitor

[0099] Filter capacitors (C7, C8):

[0100] C7 and C8 are used to filter and smooth the output voltage, reduce voltage fluctuations, and ensure a stable output 3.3V voltage.

[0101] The voltage regulator module mentioned above stabilizes the input 5V voltage to 3.3V through the BL1117 regulator, and smoothes the output through filter capacitors C7 and C8 to ensure a stable 3.3V power supply.

[0102] Combining the above-mentioned power conversion module and voltage regulation and stabilization module, when AC power fluctuations appear at the power input end, it is first converted through the BP2525 chip, and the inductor and filter capacitor are connected on both sides of the chip respectively, so that the unstable AC power output is relatively stable 5V DC power.

[0103] The relatively stable 5V DC power enters the voltage regulating module, and is converted into 3.3V DC power after voltage regulation by BL1117. It is then filtered at high frequency through capacitor C7, and further stabilized by C8 to obtain a stable 3.3V DC power.

[0104] As mentioned above, the BP2525 chip converts the AC power into a higher 5V DC power (5V), filters the input AC power, and then filters the output 5V DC power again. This is a filtering process, and a relatively stable 5V DC power is obtained.

[0105] After that, the 5V DC power is regulated and stabilized again to obtain 3.3V DC power, and a secondary filtering process is performed.

[0106] When the input AC power fluctuates and may affect the operation of the intelligent switch control system, the 220V or 110V AC power is first converted into high-voltage (5V) DC power. At this time, the unstable AC power undergoes a filtering and voltage stabilization process. Then the high-voltage (5V) DC power is stepped down to 3.3V DC power, thereby minimizing the impact of the unstable AC power. After multiple filtering and voltage regulation processes, a stable 3.3V DC power is obtained.

[0107] like Figure 4 As shown, in order to solve the technical purpose of remote control switch.

[0241] 1. Highly integrated design:

[0242] The system integrates multiple functional modules such as AC-DC conversion, multi-stage voltage regulation, filtering, relay control, signal conditioning and protection.

[0243] This high level of integration not only simplifies circuit design, but also significantly improves the overall performance and reliability of the system.

[0244] The collaborative work among modules reduces the complexity of interfaces and lowers the system failure rate.

[0245] 2. Multi-level protection mechanism:

[0246] The system adopts multiple protection strategies, including overvoltage protection, optocoupler isolation, reverse electromotive force protection, etc.

[0247] Varistors and multi-stage filter capacitors provide effective suppression of high voltage spikes and power supply noise.

[0248] Optocoupler isolation establishes a safety barrier between the high-voltage load and the control circuit, greatly improving system safety.

[0249] This multi-layer protection ensures the safe and stable operation of the system under various extreme conditions and greatly extends the life of the equipment.

[0250] 3. Intelligent control and scalability:

[0251] The use of CB2S module provides the system with powerful control and communication capabilities, supporting multiple functions such as PWM, ADC, and UART.

[0253] This design not only meets the current needs of smart home and industrial control, but also provides a solid foundation for future functional expansion and upgrading.

[0254] 4. Optimized human-computer interaction design:

[0255] The system uses intuitive key input (KEY_ON, KEY_OFF) and LED indicator light design.

[0256] The use of buttons ensures the stability of the operation signal and effectively avoids misoperation.

[0257] This design greatly improves the user experience, making system operation simpler and more intuitive, and status monitoring more convenient.

[0258] 5. High performance and high stability:

[0259] The use of BP2525 high-efficiency AC-DC converter chip and BL1117 LDO regulator significantly improves the power conversion efficiency.

[0261] This design enables the system to adapt to various complex load conditions and electromagnetic environments, ensuring stable and reliable operation.

[0262] 6. Accurate signal processing and isolation:

[0263] The AC detection module uses an optical coupler and a dedicated signal processing chip to achieve accurate AC voltage detection and isolation.

[0265] This design significantly improves the system's signal processing capability and anti-interference ability.

[0266] 7. Electromagnetic compatibility optimization:

[0267] The system greatly improves the electromagnetic compatibility of the circuit through the combination of common-mode inductors and multi-stage filter capacitors.

[0268] This not only reduces the system's sensitivity to the external electromagnetic environment, but also reduces interference to other electronic equipment.

[0269] The optimized electromagnetic compatibility design makes the system more suitable for stable operation in complex electromagnetic environments.

[0270] 8. Modular design concept:

[0271] The various functional modules of the system (such as power management, relay control, microcontroller, etc.) adopt a modular design.

[0272] This design approach not only improves the maintainability and testability of the system, but also facilitates future upgrades and customization.

[0273] The modular design also makes the system easier to adapt to different application scenarios and improves the market adaptability of the product.

[0274] The above-mentioned intelligent switch control system can solve the technical problem of microcontroller failure caused by unstable AC voltage. However, in actual use, since the intelligent switch may generate a lot of heat when in use, and since the exterior is made of injection-molded rubber and the overall structure is compact, it is easy for heat to accumulate in the switch and cannot be released, which may affect the properties of internal components, thereby causing the microcontroller to fail.

[0275] In order to achieve the technical purpose of accelerating heat dissipation, the present application provides an intelligent switch as described below.

[0276] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, an intelligent switch applies the above-mentioned intelligent switch control system. It includes a connection base 1. One side of the connection base 1 is connected to a panel 2 through an inner bolt. When in use, the connection base 1 can be connected with a corresponding circuit, so that the intelligent switch is energized.

[0277] Correspondingly, the panel 2 is provided with a mounting groove 3 in the middle of the corresponding connection seat 1. A matching groove 4 is provided in the middle of the connection seat 1. A lever 5 is provided in the matching groove 4. The lever 5 is hinged to the connection seat 1. The lever 5 can swing in the matching groove 4.

[0278] Among them, a spring piece 6 is arranged below the lever 5. A static contact 7 is arranged on one side of the spring piece 6. When the lever 5 swings to the other side as shown in the figure, the spring piece 6 is squeezed by the bottom of the lever 5 and moves away from the static contact 7, thereby achieving the technical effect of power off.

[0279] Among them, an electric control box 8 is arranged on one side of the lever 5, and the storage medium corresponding to the above-mentioned intelligent switch control system, that is, the PCB board is located in the electric control box 8, and each module is connected through a connection interface.

[0280] The core technical solution of this application is as follows:

[0281] like Fig.12 , Fig.13 , Fig.14 As shown, in order to achieve the technical purpose of improving the heat dissipation effect. The present application is provided with slide grooves 9 on both sides of the connection seat 1. A hollow sealing plate 10 is slidably connected in the slide groove 9. The sealing plate 10 is made of rubber material, has a certain elasticity, and can be deformed, and two extension strips 11 are provided on one side of the sealing plate 10 corresponding to the lever 5. The extension strip 11 is provided corresponding to the gap between the lever 5 and the matching groove 4.

[0282] Correspondingly, such as Fig.15 As shown, the lever 5 described in the present application is hollow inside and filled with liquid water. After the liquid water is filled in the lever 5, the lever 5 is sealed. A water pipe 12 is provided between the lever 5 and the two sealing plates 10 near the upper side. The water pipe 12 has the characteristic of elastic deformation. The water pipe 12 connects the lever 5 and the two sealing plates 10. The liquid water in the lever 5 can flow into the sealing plates 10 on both sides through the water pipe 12.

[0283] In such Fig.16 , Fig.17 In the state shown, the gap 17 between the lever 5 and the matching groove 4 is not filled, thereby enhancing heat dissipation. At the same time, in combination with corresponding liquid water, it can absorb the heat inside the connecting seat 1, thereby achieving the purpose of further enhancing heat dissipation.

[0284] like Fig.13 , Fig.14 As shown, the sealing plate 10 is optimized to be provided with a plurality of metal heat sinks 13 arranged in sequence. The heat sink is hollow and made of metal with good heat dissipation, and specifically copper, iron and other metals can be used. The heat sink is connected to the sealing plate 10. When in use, when the above-mentioned smart switch is placed vertically and installed in the wall switch installation position, under the action of gravity, liquid water passes through the water pipe 12 and enters the plurality of heat sinks, so that the heat absorbed by the liquid water can be quickly dissipated through the metal spring 6, thereby ensuring that the heat is discharged in time when the smart switch is working.

[0285] Through the above-mentioned dual heat dissipation effect, the heat release effect is enhanced, preventing the temperature in the connecting socket 1 from being too high and affecting the normal operation of the intelligent switch control system.

[0286] In order to prevent external dust or water vapor from entering the electric control box 8 or the connection socket 1 when the intelligent switch is turned off The technical purpose is to prevent rust and corrosion of internal components and circuits. When the lever 5 in the present application swings, the water pipe 12 has a tendency to move obliquely downward, so that the water pipe 12 pulls the sealing seats on both sides to move toward each other, so that the two extension strips 11 on one side of the sealing plate 10 enter the gap 17 between the lever 5 and the matching groove 4, thereby achieving the effect of closing the gap 17. When the intelligent switch is not working, external water vapor is prevented from entering the connecting seat 1 and the electric control box 8, thereby improving the service life of the intelligent switch.

[0287] Optimally, springs 14 are provided on both sides of the sealing plate 10, and the springs 14 are connected to fixing blocks 15. The fixing blocks 15 are fixedly connected to positioning seats 16. The positioning seats 16 are fixedly connected to the connecting seats 1. When the lever 5 drives the intelligent switch to be closed, the spring 14 stretches and has a certain elastic potential energy. Among them, the metal heat sink 13 enters the slide groove 9, and the metal heat sink 13 is recovered into the slide groove 9, reducing the safety risk of scratches caused by the metal heat sink 13.

[0288] When the lever 5 is rotated to start the intelligent switch, the extension bars 11 on both sides automatically move to both sides under the action of the spring 14, thereby exposing the gap 17 to facilitate heat dissipation.

[0289] Under the above settings, the smart switch described in the present application presents different technical effects as the lever 5 moves. When the lever 5 moves to turn on the smart switch, the gap 17 between the lever 5 and the matching groove 4 is exposed, and the liquid water inside is used to improve heat dissipation, and the metal heat sink 13 is used to achieve multiple heat dissipation effects.

[0290] When the lever 5 is moved to close the intelligent switch, the metal heat sink 13 is retracted to reduce potential safety hazards. At the same time, the extension strip 11 fills the gap 17 between the lever 5 and the matching slot 4 to prevent external dust or water vapor from entering the connection base 1.

[0291] When the lever 5 is moved again to open the intelligent switch, the sealing plate 10 is automatically reset under the action of the spring 14 to resume the heat dissipation function.

[0292] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
