DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For reference Figure 1-Figure 10 The present invention is described: Embodiment: A multifunctional fast-charging wall switch socket with voice control and USB retractable data cable comprises a bottom box 1 opened forward, and a box cover 2 is connected to the front opening of the bottom box 1.

[0036] A left installation cavity 3 and a right installation cavity 4 are respectively arranged on the left and right sides of the bottom box 1, and a partition 5 is arranged between the left installation cavity 3 and the right installation cavity 4, and the partition 5 divides the space between the left installation cavity 3 and the right installation cavity 4 into an upper installation cavity 6 and a lower installation cavity 7. The internal space of the bottom box is carefully divided, and this partition design provides a reasonable layout for the installation of different functional components.

[0037] This partition design provides a reasonable layout for the installation of different functional components, which is mainly reflected in the following aspects: First, it improves space utilization. By finely dividing different installation cavities, the space inside the bottom box can be fully utilized, so that each component can be reasonably arranged in a limited space, avoiding space waste and mutual interference between components.

[0038] Second, it is easy to install and maintain. Different components are installed in specific installation cavities, making the installation process more orderly and efficient. During installation, the staff can quickly find the installation location of each component according to the division of the installation cavity, improving the installation speed and accuracy. At the same time, in the later maintenance process, the partition design also makes troubleshooting easier. If a component has a problem, the maintenance personnel can quickly locate the installation cavity where the component is located and perform targeted maintenance without affecting other unrelated components.

[0039] Third, it enhances the stability and reliability of the product. The design of each installation cavity can be optimized according to the characteristics of the component to provide a more stable installation environment for the component. For example, for some circuit boards that are sensitive to vibration, a shock-absorbing structure can be set in the installation cavity or a more secure fixing method can be adopted to ensure its stability during use. At the same time, the partition design can also reduce problems such as electromagnetic interference between components and improve product reliability.

[0040] A first circuit board 8 is installed in the left installation cavity 3. The first circuit board is plugged and fixedly connected with the grooves on the upper and lower side walls of the left installation cavity. This connection method not only ensures the stable installation of the circuit board, but also facilitates installation and removal.

[0041] The first circuit board is plugged and fixedly connected to the grooves on the upper and lower side walls of the left installation cavity. This connection method has significant advantages. On the one hand, it ensures the stable installation of the circuit board. When the first circuit board is inserted into the groove, the shape and size of the groove match the edge of the circuit board, which can tightly clamp the circuit board to prevent it from loosening or falling off due to vibration, external force and other factors during use. This stable installation method is crucial to ensure the normal operation of the circuit board, especially when the wall switch socket may be subject to a certain degree of vibration and external force impact.

[0042] On the other hand, this connection method is easy to install and disassemble. When installing, the staff only needs to align the first circuit board with the grooves on the upper and lower walls of the left installation cavity and gently insert it to complete the installation. The operation is simple and quick. When the circuit board needs to be repaired or replaced, it can also be easily pulled out of the groove without using complex tools or performing cumbersome operations. This convenient installation and disassembly method greatly improves production efficiency and maintenance convenience, and reduces maintenance costs.

[0043] In addition, this plug-in fixed connection method also has good heat dissipation performance. Since there is a certain gap between the circuit board and the wall of the installation cavity, air can flow through these gaps, thereby effectively removing the heat generated by the circuit board when it is working. Good heat dissipation performance can extend the service life of the circuit board and improve the reliability of the product.

[0044] A cable reel 9 is fixedly installed in the right installation cavity 4, and the cable reel 9 has a charging data cable 10 that can be stretched and automatically retracted. It provides a convenient charging method for users. Users can stretch the data cable for charging as needed, and the data cable automatically retracts after use, avoiding the clutter and entanglement of the data cable.

[0045] First, the fixed installation of the cable reel in the right mounting cavity ensures its stability. The space size and shape of the right mounting cavity are carefully designed to perfectly accommodate the cable reel so that it will not shake or shift during use. This fixed installation method ensures the normal operation of the cable reel and avoids problems such as the data cable stretching and retraction being not smooth due to looseness.

[0046] The reel's stretchable and automatically retractable charging cable provides users with a convenient way to charge. Users can easily stretch the cable according to actual needs and connect it to the device that needs to be charged. This stretchable design allows users to charge without being restricted by the length of the cable, and can freely adjust the length of the cable according to the location of the device and the usage scenario, improving the flexibility and convenience of charging.

[0047] When you are done using it, the data cable can automatically retract into the reel. This function effectively avoids the clutter and entanglement of the data cable. In traditional charging methods, data cables are often placed randomly and easily tangled together, which is not only unsightly, but also takes time to untangle the tangled data cable the next time you use it. The automatic retraction design allows the data cable to be neatly stored in the reel when not in use, keeping the environment clean and orderly.

[0048] In addition, the automatically retractable data cable can also reduce the damage caused by long-term exposure to the outside. When the data cable is not in use, it is stored in the reel to avoid being affected by external forces, dust pollution, water erosion and other factors, thus extending the service life of the data cable.

[0049] A second mounting cavity 11 corresponding to the upper mounting cavity 6 is provided on the inner side of the box cover 2, and a second circuit board 12 is fixedly installed in the second mounting cavity 11. The second circuit board 12 is adapted to be connected with the second mounting cavity 11, and the second circuit board 12 is restricted by the box cover 2 and the bottom box 1 in the front-back direction, thereby ensuring the stability of the circuit board during use.

[0050] First, the second mounting cavity corresponding to the upper mounting cavity is arranged on the inner side of the box cover, making the overall structure more compact and reasonable. This corresponding design makes full use of the space, avoids unnecessary waste of space, and also makes the layout of various functional components more orderly.

[0051] The second circuit board is fixedly mounted in the second mounting cavity, and the second circuit board is adaptively connected to the second mounting cavity. This means that the second circuit board can be tightly mounted in the second mounting cavity without looseness or shaking. The adaptive connection ensures a good fit between the circuit board and the mounting cavity, thereby improving the stability of the circuit board.

[0052] In the front-to-back direction, the second circuit board is restricted by the box cover and the bottom box. This restriction further enhances the stability of the circuit board. The box cover and the bottom box together provide a stable installation environment for the second circuit board, preventing the circuit board from being displaced or deformed due to external forces during use. For example, when the wall switch socket is slightly impacted or vibrated, due to the restrictions of the box cover and the bottom box, the second circuit board can remain in place and will not be affected, thereby ensuring its normal operation.

[0053] The bottom of the lower installation cavity 7 is provided with an installation slot 13, and the bottom of the installation slot 13 is provided with a wire entry hole 14 that penetrates the rear side of the bottom box 1. The network wire is connected through the wire entry hole 14. The lower side wall of the installation slot 13 is provided with a fixing hole 15 that penetrates the lower side wall of the bottom box 1. There are two installation slots 13, and the two installation slots 13 are arranged at intervals on the left and right, providing a convenient location for the access and fixation of the network wire.

[0054] First, the bottom of the installation slot is set with a wire entry hole that runs through the rear side of the bottom box, providing a clear path for the access of network wires. Network wires can be directly inserted through the wire entry hole, making the access of wires more neat and standardized. This design avoids the confusion and safety hazards that may be caused by random access of wires, and ensures the orderliness of wire access.

[0055] Secondly, a fixing hole is set on the lower side wall of the installation slot and penetrates the lower side wall of the bottom box, which provides a reliable way to fix the network wire. After the network wire is connected from the wire entry hole, the wire can be firmly fixed in the installation slot through the fixing hole using a fixing bolt or other fixing device. This can prevent the wire from loosening or falling off during use, ensuring the stability of the circuit connection.

[0056] Furthermore, two installation slots spaced apart on the left and right further improve the convenience of network wire access and fixation. The two installation slots can be connected to different network wires, such as live wire and neutral wire, or provide independent power access for different circuit modules. This design makes the layout of wires more reasonable and avoids mutual interference between wires. At the same time, the left and right interval settings also facilitate the operation of installation and maintenance personnel and improve work efficiency.

[0057] An annular first copper piece 16 is installed in the installation groove 13. The first copper piece 16 is provided with a wiring groove 17 corresponding to the wire entry hole 14. The first copper piece 16 is provided with a connecting hole 18 corresponding to the fixing hole 15. The connecting hole 18 and the fixing hole 15 are connected with a fixing bolt 19. The network wire extends from the wire entry hole 14 into the wiring groove 17 and is fixed by the tightened fixing bolt 19. The network wire can be firmly fixed in the wiring groove by tightening the fixing bolt.

[0058] First, the annular first copper piece is installed in the installation slot, providing a reliable conductive medium for the connection of network wires. Copper has good conductivity and can ensure efficient transmission of electricity. The annular design makes the first copper piece more tightly combined with the installation slot, and it is not easy to loosen or shift.

[0059] The first copper part is provided with a wiring slot corresponding to the wire entry hole, which provides a special connection position for the network wire. The network wire extends into the wiring slot from the wire entry hole. This design makes the connection of the wire more standardized and neat. The size and shape of the wiring slot are carefully designed to accommodate the network wire and ensure good contact between the wire and the first copper part.

[0060] The first copper piece is also provided with a connecting hole corresponding to the fixing hole, and fixing bolts are connected in the connecting hole and the fixing hole. When the network wire is inserted into the wiring slot, the network wire can be firmly fixed in the wiring slot by tightening the fixing bolts.

[0061] A power board 20 is provided at the bottom of the lower mounting cavity 7, and the power board 20 is in contact with the bottom of the lower mounting cavity 7. The power board 20 is located at the front side of the mounting groove 13 and restricts the first copper piece 16 in the mounting groove 13. This design is equivalent to fixing the first copper piece, and effectively avoids the movement and loss of the first copper piece during the disassembly and assembly of the wall switch socket, thereby improving the reliability and stability of the product.

[0062] This restriction on the first copper piece has many advantages. First, during the disassembly and assembly of the wall switch socket, the first copper piece will not move due to accidental collision or loosening. This greatly reduces the difficulty of operation during installation and maintenance and improves work efficiency. Second, the risk of losing the first copper piece is avoided. If the first copper piece is easy to move during the disassembly and assembly process, it may accidentally fall or be placed in the wrong position, resulting in incomplete installation or requiring extra time to find the lost copper piece. However, through the restriction of the power board, the first copper piece is always kept in the correct position, improving the reliability and stability of the product.

[0063] It also includes a second copper piece connected to the first copper piece 16, and the second copper piece includes a plate body part 21, which is arranged in the up and down direction. The upper end of the plate body part 21 is provided with a power connection part 22 extending backward into the wiring groove 17 (the power connection part 22 is fixed by the fixing bolt 19), and the rear end of the plate body part 21 is provided with a plug-in part 23 extending forward, and the plug-in part 23 includes two left and right clamping arms, and the plug pins of the plug are inserted between the two clamping arms to form an electrical connection.

[0064] The plate portion of the second copper part is arranged in the up-down direction, providing a stable structural support for the entire copper part. The upper end of the plate portion is provided with a power connection portion extending backward into the wiring slot, and this power connection portion is in close contact with the first copper part to achieve power transmission. The power connection portion is fixed by fixing bolts to ensure the firmness and stability of the connection. During the installation process, the fixing bolts firmly fix the power connection portion in the wiring slot of the first copper part to prevent it from loosening or falling off, thereby ensuring the reliability of power transmission.

[0065] The rear end of the board body is equipped with a plug-in part that extends forward. This plug-in part has a unique design and includes two clamping arms on the left and right. When the plug pin is inserted between the two clamping arms, an electrical connection is formed. This clamping design makes the plug insertion more stable and not easy to loosen. At the same time, the clamping arm can tightly wrap the pin to ensure a good contact area, thereby improving the efficiency of power transmission.

[0066] The power board 20 is provided with a connection groove 24 corresponding to the plate body 21, and the connection groove 24 runs through the front and rear sides and the upper side of the power board 20. The left and right sides of the connection groove 24 are provided with plug-in grooves 25, and the left and right sides of the plate body 21 are connected to the plug-in grooves 25. It is equivalent to the second copper piece being plugged and connected with the plug-in grooves 25 on the power board 20 through the plate body 21, which is equivalent to fixing the second copper piece. This design is equivalent to fixing the second copper piece, and in the process of disassembling and assembling the wall switch socket, the movement and loss of the second copper piece are also avoided.

[0067] The connection slot provided on the power board runs through the front and rear sides and the upper side of the power board. This design provides a specific accommodation space for the plate body of the second copper member so that it can be inserted into it in a suitable manner. The plug-in slots provided on the left and right sides of the connection slot are the key. They are adapted to the left and right sides of the plate body of the second copper member so that the plate body can be accurately inserted into these plug-in slots, thereby realizing the plug-in connection between the second copper member and the power board.

[0068] This plug-in connection method is equivalent to creating a stable "positioning device" for the second copper piece. When disassembling and assembling a wall switch socket, it often involves moving, disassembling and reinstalling various components. During the process, it is easy for the components to change position or even be lost due to external forces or collisions between components. However, since the plate part of the second copper piece is firmly plugged into the plug slot of the power board, it is difficult for external forces to easily change its position, which greatly avoids unnecessary movement of the second copper piece during disassembly and assembly.

[0069] At the same time, this fixing method also eliminates the risk of the second copper part being lost. During the entire disassembly and assembly process, it will always be confined to the socket of the power strip and will not be lost due to being out of its original position. This ensures that all parts are in the correct position before and after operation, providing a guarantee for subsequent assembly and normal use of the socket.

[0070] The power board 20 is provided with power strips that extend to the first circuit board 8, the second circuit board 12, and the cable reel 9 and realize electrical connection. The power board and the power strip form an integrated component for electrical connection of the circuit. This design facilitates the electrical connection between the first circuit board, the second circuit board, the cable reel, and the copper parts. At the same time, the overall regular structure avoids the appearance of messy wires, making the product more beautiful and neat, and also improving the reliability and safety of the circuit.

[0071] First of all, the power strips are equipped on the power board, which extend to the first circuit board, the second circuit board and the cable reel respectively. These power strips are like "power bridges", closely connecting the power board with various key power-consuming components. For the first circuit board, the power strip can accurately transmit the power from the power supply to ensure its normal operation, so that it can smoothly realize related functions such as voice control. Similarly, the second circuit board also relies on the power strip to obtain stable power, and then it can accurately identify the externally connected devices, and reasonably adjust the output voltage and current according to the type and needs of the device to achieve functions such as fast charging. After the cable reel is supplied with power through the power strip, it can drive the internal mechanism to operate normally, realizing the convenient function of the charging data cable being stretchable and automatically retracted.

[0072] The power strip and the power strip together form an integrated component for electrical circuit connection. This integrated design concept greatly facilitates the electrical connection between various components. In the past, when connecting different components through scattered wires, complex wiring planning is often required, and the wires are easily entangled and crossed with each other, which not only increases the difficulty and time cost of installation, but also makes it very difficult to troubleshoot line faults during subsequent use and maintenance. Now, with the integrated design of the power strip and the power strip, the power transmission path between the various components is clear. The installer only needs to operate according to the established connection method to quickly complete the circuit construction, greatly improving production efficiency.

[0073] At the same time, this design makes the structure inside the entire socket more regular and orderly. There are no more messy and spreading wires. From the appearance, the product looks more beautiful and neat, and can be better integrated with the modern home environment, which improves the overall texture of the product. More importantly, the regular circuit structure also significantly improves the reliability and safety of the circuit. Scattered and messy wires are prone to wear and tear, insulation damage, and other problems, which in turn cause safety hazards such as short circuits and leakage. The connection through the power strip reduces the number of wires used and the interference between them, reduces the possibility of such failures, ensures that the circuit can operate stably and safely, and provides strong guarantees for users to use this multi-functional fast charging wall switch socket with confidence.

[0074] A first power connection bar 31 electrically connected to the first circuit board 8 extends to the left from the left side of the lower end of the power connection board 20, a second power connection bar 32 electrically connected to the charging data cable 10 on the cable reel 9 extends to the right from the right side of the lower end of the power connection board 20, and a third power connection bar 33 electrically connected to the second circuit board 12 extends forward from the upper end of the power connection board 20.

[0075] The first connection bar 31 extending to the left from the left side of the lower end of the connection board 20 is mainly used to achieve electrical connection with the first circuit board 8 .

[0076] The second power strip 32 extending to the right from the right side of the lower end of the power strip 20 is responsible for establishing an electrical connection with the charging data cable 10 on the cable reel 9 .

[0077] The third connection bar 33 extending forward from the upper end of the connection board 20 is electrically connected to the second circuit board 12 .

[0078] The power board 20 is provided with a power connection area 34 that is in electrical contact with the two first copper parts 16. The power board 20 is provided with two first conductive wires 35, one end of the two first conductive wires 35 is respectively connected to the two power connection areas 34, and the other end of the two first conductive wires 35 is electrically connected to the first circuit board 8 through the first power connection bar 31. The power board 20 is provided with two second conductive wires 36, one end of the two second conductive wires 36 is respectively connected to the two power connection areas 34, and the other end of the two second conductive wires 36 is electrically connected to the second circuit board 12 through the third power connection bar 33. The power board 20 is provided with a third conductive wire 37, the third conductive wire 37 passes through the first power connection bar 31 and the second power connection bar 32, and the two ends of the third conductive wire 37 are respectively electrically connected to the first circuit board 8 and the charging data line 10 on the cable reel 9.

[0079] The first conductive wire 35, the second conductive wire 36, and the third conductive wire 37 are formed by a conductive layer (the conductive layer is made of conductive material) covering the connection board 20, the first connection bar 31, the second connection bar 32, and the third connection bar 33, and the connection board 20, the first connection bar 31, the second connection bar 32, and the third connection bar 33 are made of insulating material.

[0080] First, the power connection area 34 provided on the power connection board 20 and in electrical contact with the two first copper pieces 16 plays a key role. The two power connection areas 34 are like "nodes" for gathering and transferring electric energy. Through the electrical contact with the first copper piece 16, the electric energy introduced from the outside can be effectively collected, so as to prepare for the subsequent transmission of electric energy to various circuit boards, reels and other components.

[0081] Next, let's look at the two first conductive wires 35. One end of each of them is connected to the two power connection areas 34, and the other end is electrically connected to the first circuit board 8 through the first power connection bar 31. This means that the first conductive wires 35 are responsible for accurately transmitting the electric energy obtained from the power connection area 34 to the first circuit board 8. Since the first conductive wires 35 are formed by a conductive layer covering the power connection board 20 and the first power connection bar 31, and the conductive layer is made of conductive material, they can efficiently conduct current and ensure that the first circuit board 8 can stably receive the required electric energy.

[0082] Similarly, one end of the two second conductive wires 36 is also connected to the two power connection areas 34 respectively, and the other end is electrically connected to the second circuit board 12 through the third power connection bar 33. This design makes the second conductive wires 36 become a "power bridge" connecting the power connection area 34 and the second circuit board 12, and smoothly transmits the collected electric energy to the second circuit board 12.

[0083] The third conductive line 37 is even more unique, it passes through the first power connection bar 31 and the second power connection bar 32, and the two ends are respectively electrically connected to the charging data line 10 on the first circuit board 8 and the cable reel 9. The unique layout of this conductive line realizes the power interaction between the first circuit board 8 and the cable reel 9, so that the two can work together and cooperate with each other in some functional implementations, such as the first circuit board 8 adjusts the working state of the cable reel 9 through the control signal with the help of the third conductive line 37, or the cable reel 9 feeds back its own working state to the first circuit board 8, etc., further enriching the functions of the entire socket.

[0084] It is worth mentioning that the power board 20, the first power strip 31, the second power strip 32, and the third power strip 33 are made of insulating materials, which is extremely important. The use of insulating materials can effectively prevent the leakage of current in places where it should not be conducted, avoid electrical faults such as short circuits, and ensure the safety and stability of the entire circuit system. The first conductive wire 35, the second conductive wire 36, and the third conductive wire 37 conduct current through the covered conductive layer, which not only cleverly utilizes the structural space of the power board and each power strip, but also realizes efficient and orderly power transmission, making the circuit layout inside the entire socket more regular and compact, while also reducing the clutter that may be caused by traditional wire connections, and improving the overall reliability and aesthetics of the product.

[0085] To sum up, the ingenious combination of these conductive wires, the power strips and the power boards has built a circuit system that is fully functional, safe, reliable and reasonably laid out. This is the core of the multifunctional fast-charging wall switch socket that can stably perform its various functions.

[0086] A cover 26 is provided on the front side of the lower mounting cavity 7, and the cover 26 is fixedly connected to the side wall of the lower mounting cavity 7. The cover 26 forms a restriction on the front side of the power board to connect to the power board, and the rear side of the power board is restricted by the bottom of the lower mounting cavity 7. This fixed connection method allows the cover to be firmly positioned at the front side of the lower mounting cavity. It forms a restriction on the front side of the power board to connect to the power board, and combined with the restriction of the rear side of the power board to the bottom of the lower mounting cavity 7, it is like creating a "fixed frame" in the front-to-back direction for the power board. In this way, the position of the power board in the front-to-back direction is firmly fixed, and it will not easily move forward and backward, further enhancing the stability of the power board in the entire socket structure.

[0087] The connection board is a key component for realizing electrical connection between multiple components, and its stability is directly related to whether the entire circuit system can operate normally. Through the dual restrictions of the cover 26 and the bottom of the lower mounting cavity, even when the socket is affected by external forces such as external vibration, collision or plugging and unplugging operations in daily use, the connection board can still remain in place, ensuring that the connection with the first copper piece, the second copper piece, and each conductive wire and the connection strip is always reliable, thereby ensuring the stable transmission of electricity and the normal performance of various functions.

[0088] A USB connector 27 and a Type-C connector 28 are provided on the first circuit board 8. These two different types of interfaces can meet the charging needs of many electronic devices on the market. Nowadays, various types of smartphones, tablet computers, smart wearable devices, etc. mostly use USB interfaces or more advanced Type-C interfaces for charging and data transmission. Setting these two interfaces on the wall switch socket means that users no longer need to find additional charging adapters. They only need to directly plug the charging cable corresponding to the device into the corresponding interface to easily charge the device, which greatly improves the convenience of charging and makes the socket a convenient charging "hub", which better adapts to the diverse electronic device usage habits of modern people.

[0089] The second circuit board 12 is provided with a voice control module. It integrates an advanced voice recognition chip and a microphone array. This combination provides a solid technical guarantee for accurately recognizing user voice commands. The microphone array can collect sound signals from multiple directions, enhance the reception effect of voice, and reduce the interference of external environmental noise on voice recognition. The advanced voice recognition chip uses complex algorithms to quickly and accurately analyze and recognize the collected voice signals and convert them into corresponding control commands.

[0090] With the help of this voice control module, users can remotely control various electrical appliances at home, such as lighting, fans, and air conditioners. In the past, people needed to walk near the appliance or find the corresponding remote control to operate it, but now they can easily complete the corresponding operation by simply issuing clear and unambiguous instructions such as "turn on the living room lights" or "turn off the bedroom fan" without any physical contact. This remote voice control method not only brings great convenience to users, especially when their hands are inconvenient or they are far away from the appliance, but also highlights its advantages; it also improves home safety to a certain extent, such as avoiding safety hazards such as bumps caused by groping for switches in the dark, and also reducing the risk of electric shock caused by frequent touching of electrical switches.

[0091] An isolation plate 29 is disposed between the left and right mounting grooves 13 , and a slot 30 corresponding to the isolation plate 29 is disposed on the power board 20 . The slot 30 runs through the front and rear sides and the upper side of the power board 20 .

[0092] One end of the charging data cable 10 is fixedly connected to the cable reel 9 , and the other end of the charging data cable 10 is a movable end and is connected to a plug connector 38 . A placement groove 39 for placing the plug connector 38 is provided on the front side of the box cover 2 .

[0093] The structure of the cable reel 9: The cable reel 9 usually has a shell, and the shape of the shell is generally adapted to the right mounting cavity 4. A cable outlet is reserved on the shell, and the charging data cable 10 passes through this outlet. The internal core is the reel, which is a key component for the cable reel to realize the data cable storage function. One end of the data cable 10 is fixed on the reel. When the user stretches the data cable, the reel will rotate accordingly and release the data cable from the cable outlet of the shell. A spring mechanism is also provided inside the cable reel 9. The spring is an important component that provides automatic retraction power for the data cable. When the user stretches the data cable, the spring will be stretched and store elastic potential energy. One end of the spring is fixed to a fixed position of the reel or the shell, and the other end is connected to a component that can be displaced as the reel rotates. When the user stops stretching the data cable, the spring will drive the reel to rotate in the opposite direction under the action of the elastic potential energy, and automatically retract the data cable into the cable reel. The cable reel 9 needs to be electrically connected to the power board 20 to obtain electricity to charge external devices. It may be connected via a connection to a second connection bar 32 on the connection board.

[0094] The front edge of the bottom box 1 is fixedly connected with a metal frame 40, and the front side of the box cover 2 is provided with a panel 41, which is fixedly connected with the metal frame 40. The cover 26 is provided with a hole corresponding to the plug-in portion 23 .

[0095] Working principle: External power supply access: The network wire is connected from the wire entry hole 14 of the bottom mounting groove 13 of the bottom mounting cavity 7 of the bottom box 1, and enters the wiring groove 17 of the first annular copper piece 16 in the mounting groove 13, and the wire is fixed by tightening the fixing bolt 19. The first copper piece 16 is tightly matched with the second copper piece, and the power connection part 22 of the second copper piece is also fixed by the fixing bolt 19, so as to realize the connection between the network wire and the second copper piece.

[0096] Power distribution: The power board 20 is located at the bottom of the lower installation cavity 7, fits with the bottom of the lower installation cavity 7, and limits the first copper piece 16 in the installation groove 13. The power board 20 is provided with power strips extending to the first circuit board 8, the second circuit board 12, and the cable reel 9 and realizing electrical connection. After the power connected to the network wire is transmitted to the power board 20 through the first copper piece 16 and the second copper piece, the power strips on the power board 20 distribute the power to various components.

[0097] Function of the first circuit board 8: The first circuit board 8 is installed in the left installation cavity 3 and is plugged and fixed into the grooves on the upper and lower side walls of the left installation cavity 3. It starts working after receiving power from the power strip of the power board 20. If there is a voice control function, the relevant circuits on the first circuit board 8 will process the voice signal. For example, when the user issues a voice command, the microphone (if any) converts the sound signal into an electrical signal, and the chip on the first circuit board 8 identifies and decodes these electrical signals, controls the switch state of the socket or adjusts other functional parameters according to the content of the command. At the same time, the USB connector 27 and the Type-C connector 28 on the first circuit board 8 can provide charging interfaces for external devices, distribute the received power to these interfaces through the internal circuit, and charge the device with appropriate voltage and current.

[0098] Function of the second circuit board 12: The second circuit board 12 is installed in the second installation cavity 11 on the inner side of the box cover 2, and is restricted by the box cover 2 and the bottom box 1 in the front and rear directions. After obtaining power from the power strip of the power board 20, the second circuit board 12 starts to work. The voice control module on it integrates a voice recognition chip and a microphone array, which can accurately recognize user voice commands and realize remote voice control of home lighting, fans, air conditioners and other electrical appliances. After receiving the voice command, the voice recognition chip processes the voice signal, converts it into a control signal, and sends the control signal to the corresponding electrical device through wireless communication (such as Wi-Fi, Bluetooth, etc.) or other methods (such as wired connection with the home automation system) to realize remote control. In addition, the second circuit board 12 may also participate in the control of the charging function of the socket itself, such as identifying the type of device connected to the socket, adjusting the charging parameters, etc.

[0099] Working principle of the cable reel 9: The cable reel 9 is located in the right installation cavity 4 and obtains electricity through the second power connection bar 32 of the power connection board 20. There are a reel and a spring mechanism inside the cable reel 9. When the user stretches the charging data cable 10, the reel starts to rotate, the spring is stretched and stores elastic potential energy. One end of the data cable 10 is fixed on the reel, and as the reel rotates, the data cable is pulled out from the outlet of the cable reel 9 housing. When the user stops stretching, the reel will rotate in the opposite direction under the action of the elastic potential energy of the spring, and the charging data cable 10 will automatically retract into the cable reel 9.

[0100] Charging process of the charging data cable 10: The charging data cable 10 is connected to the cable reel 9. When the external device is connected to the socket via the data cable, the second circuit board 12 will provide the device with appropriate charging voltage and current through the cable reel 9 and the data cable according to the needs of the device. For example, for a mobile phone that supports the fast charging protocol, the socket will quickly charge the mobile phone through the data cable according to the fast charging standard required by the mobile phone, such as Qualcomm's QuickCharge or Huawei's SuperCharge and other protocols. At the same time, the other end of the charging data cable 10 is an active end and is connected to a plug connector 38. A placement slot 39 for placing the plug connector 38 is provided on the front side of the box cover 2. When not in use, the plug connector 38 can be placed in the placement slot 39, and when in use, it can be taken out and connected to the device for charging.

[0101] The second circuit board 12 and the first circuit board 8 can communicate with each other.

[0102] Core components and principles of voice control module: The voice control module integrates an advanced voice recognition chip and a microphone array. The collaboration between the two is the key to accurate voice command recognition. The voice recognition chip uses advanced algorithms and deep learning technology to process the sound signals collected by the microphone array. The microphone array can capture sounds from multiple directions. By receiving the time difference and intensity difference of sounds from different microphones, it can not only enhance the ability to capture voice signals, but also effectively filter out noise interference in the surrounding environment, thereby accurately extracting the voice commands issued by the user.

[0103] Functional advantages and convenience: Users only need to issue simple commands such as "turn on the living room lights" or "turn off the bedroom fan" in natural language to remotely control the corresponding electrical appliances in their home, without having to walk to the appliances or find the corresponding remote controls for manual operation as in the traditional way. This contactless control method greatly improves the convenience of operation, especially when your hands are busy, you are far away from the appliances, or the ambient light is dim. From the perspective of home safety, it avoids safety risks such as bumps and electric shocks caused by groping for switches and plugging in and out electrical plugs in the dark, creating a safer and more comfortable home environment for users.

[0104] USB retractable data cable design, retractable mechanism features and advantages: Its built-in telescopic mechanism is a very clever design. When not in use, the data cable can be completely stored inside the switch panel, making the entire switch panel look neat and tidy, without the mess caused by the exposure of traditional data cables, and also avoiding the data cable from being contaminated by dust, liquids, etc. and damaged by accidental pulling due to long-term exposure. When the user needs to charge, just pull the data cable gently, and the data cable can be smoothly extended, and the length can be freely adjusted according to the actual usage scenario. Whether the device is placed close to the switch panel or a little further away, the appropriate data cable length can be obtained on demand, which effectively solves the inconvenience of the traditional fixed cable length not being able to flexibly adapt to different usage distances.

[0105] Multi-protocol fast charging support, protocol compatibility and automatic adaptation functions: The USB interface supports multiple mainstream fast charging protocols such as QC3.0, PD3.0, AFC, SCP, etc., which means it is compatible with almost all electronic devices on the market that support fast charging. The built-in intelligent recognition system can automatically detect the type of connected device and its charging requirements, and then accurately provide the most suitable charging power according to the fast charging protocol supported by the device. For example, when connecting a mobile phone that supports the QC3.0 protocol, the socket will output the corresponding high voltage and high current according to the protocol standard, so that the mobile phone enters the fast charging mode; when connecting a tablet that supports the PD3.0 protocol, it can switch to the charging parameters suitable for the tablet for charging, giving full play to the fast charging potential of different devices.

[0106] Intelligent identification and security protection, the role of intelligent identification chips: The built-in intelligent identification chip plays a key role in safety protection. It can quickly and accurately identify the type of connected devices, and automatically adjust the output voltage and current according to the electrical characteristics of different devices. For example, for some low-power smart wearable devices, it will output lower voltage and current to ensure safe charging; while for devices with high power requirements such as laptops, it will increase the output power accordingly to meet their charging needs. This precise adjustment mechanism not only ensures the normal charging of the device, but also effectively prevents overcharging that may be caused by mismatched charging parameters, avoiding the risk of battery bulging, damage, and even safety accidents.

[0107] Multiple security mechanisms guarantee: In addition to intelligently adjusting the output parameters, the switch socket is also equipped with multiple safety mechanisms such as over-temperature protection, over-current protection, and lightning protection. When the socket is overheated during use, it may be due to long-term charging or excessive external ambient temperature. The over-temperature protection mechanism will automatically start to reduce the output power or cut off the power supply to prevent safety hazards such as fire caused by high temperature. Over-current protection takes effect when the current in the circuit exceeds the safety threshold, cutting off the current in time to avoid damage to the device and the socket itself due to excessive current. Lightning protection can effectively block the impact of instantaneous high voltage and high current generated by lightning on the socket and connected devices when encountering thunder and lightning weather, fully protecting the user's personal safety and the safety of the equipment, so that users can use the switch socket with confidence.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
