[0010] As a further improvement to the above technical solution, the detection mechanism includes a micro-motion detection component and a light detection component, and the circuit board is electrically connected to the micro-motion detection component and the light detection component respectively.

[0011] As a further improvement to the above technical solution, the back panel includes a stepped outer frame and an inner frame, the first light strip is arranged around the outer end face of the inner frame, and the inner frame is embedded in the cover plate.

[0012] As a further improvement to the above technical solution, the inner frame is provided with a groove, the groove connects the mounting slot and the mounting cavity, and the two ends of the first light strip are fastened to the groove.

[0013] As a further improvement to the above technical solution, the outer frame, the outer end face of the first light strip, and the outer end face of the cover plate are aligned.

[0034] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0035] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings.

[0037] It should be noted that in the attached diagram, the X direction points from the back to the front of the expansion socket; the Y direction points from the left to the right of the expansion socket; and the Z direction points from the bottom to the top of the expansion socket.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 3 The following are several embodiments of the expansion panel and expansion socket of this utility model.

[0040] like Figures 1 to 3 As shown, in this embodiment of the utility model, the extension panel 100 is connected to the base box 200. The base box 200 is a conventional 86-type base box, which is stably fixed in the wall by pre-embedding with grooves and filling the gaps with cement.

[0041] Therefore, if the extension panel 100 is replaced on the basis of the existing ordinary socket, since the back box 200 connected to the extension panel 100 is the existing 86-type back box, the extension panel 100 can be directly installed on the back box 200 on the original wall, and the replacement and installation can be completed quickly and easily.

[0042] It is understood that the extension panel 100 includes a backplate 300 and a cover plate 400 for embedded connection, such as Figure 1 As shown, this ensures a secure connection between the two. An outer mounting groove is formed between the back plate 300 and the cover plate 400 after the connection is established. This mounting groove is used to limit the installation of the first light strip 610. A hollow mounting cavity is formed around the back plate 300 and the cover plate 400 after the connection is established. This mounting cavity is used to install the circuit board 500 and protect the circuit board 500 from dust and moisture.

[0043] Understandably, the circuit board 500 is electrically connected to both the first LED strip 610 and the detection mechanism. Specifically, the detection mechanism detects environmental data and converts the data into electrical signals, which are then sent to the circuit board 500. The circuit board 500 adjusts the first LED strip 610 based on the acquired environmental data, thereby enabling the first LED strip 610 to automatically switch on and off, adjust brightness, and / or adjust color temperature without requiring manual adjustment by the user, making the use of the extension panel 100 more convenient.

[0044] It is understandable that wiring components 800 and conductive components 700 are electrically connected to opposite sides of circuit board 500. Specifically, the wires pre-embedded in the wall pass through the junction box 200 and back plate 300, and then connect to wiring components 800, so that the neutral wire, live wire and ground wire in the pre-embedded wire are respectively connected to the corresponding parts of wiring components 800. Conductive components 700 are electrically connected to wiring components 800 through circuit board 500.

[0045] It is understandable that there is one wiring component 800 and multiple conductive components 700, such as... Figure 1 As shown. Thus, taking the neutral wire as an example, the neutral wires of multiple conductive components 700 are connected in parallel via circuit board 500 and then connected in series with the neutral wire of wiring component 800. Similarly, the connection method of the live wire and ground wire of conductive component 700 is the same as the connection method of the neutral wire.

[0046] Moreover, since one wiring component 800 is electrically connected to multiple conductive components 700 via the circuit board 500, only one junction box 200 with wires is needed. The live wire, neutral wire, and ground wire in the wires are connected to the wiring component 800 respectively, which can enable multiple conductive components 700 to be powered on. This allows multiple electrical devices to be powered on and used simultaneously through the expansion panel 100, without the need to drill additional holes in the wall to expand multiple conductive components 700, thus reducing costs.

[0047] Understandably, when installing the extension panel 100, it is only necessary to pre-embed a back box 200 in the wall and reserve wires to pass through the back box 200. Users can install the extension panel 100 on the back box 200 in the wall in the same way as a single ordinary socket.

[0048] In some embodiments, the detection mechanism includes a micro-motion detector, which is disposed in the environment and electrically connected to the circuit board 500. Thus, the micro-motion detector can detect human activity in the environment. When a human body is detected, the micro-motion detector sends a presence information to the circuit board 500. At this time, the circuit board 500 adjusts the first light strip 610 based on the presence information, increasing the brightness of the first light strip 610. This allows the user to quickly determine the position of the extension panel 100 based on the first light strip 610, enabling the user to conveniently use the extension panel 100 and its connected electrical devices in dim environments or at night. Alternatively, the circuit board 500 can also adjust the color temperature of the first light strip 610 based on human activity, making the color temperature of the first light strip 610 more comfortable for the user.

[0049] In other embodiments, the detection mechanism includes a light detection element disposed in the environment and electrically connected to the circuit board 500. Thus, the light detection element can also detect changes in ambient light. When a change in ambient light conditions is detected, the light detection element sends the light condition information to the circuit board 500. At this time, the circuit board 500 adjusts the first LED strip 610 based on the light condition information. This allows for reducing or turning off the brightness of the first LED strip 610 when the lighting conditions are sufficient, saving energy; and turning on or increasing the brightness of the first LED strip 610 when the lighting conditions are poor, making it easier for users to clearly use the extension panel 100 or its connected electrical devices in dim environments. Alternatively, the circuit board 500 can adjust the color temperature according to the light conditions to improve user comfort.

[0050] In this embodiment, the detection mechanism includes a micro-motion detection component and a light detection component. The circuit board 500 intelligently combines the presence of human beings and light conditions in the environment to achieve energy-saving lighting control, safety monitoring, and intelligent scene automatic switching functions, providing users with a more comfortable and safe living experience while optimizing energy utilization.

[0051] It is understandable that the micro-motion detection component can be an infrared sensor or an ultrasonic sensor, and the light detection component can be a photoresistor.

[0052] In this embodiment, the first light strip 610 is equipped with a pulse width modulation (PWM) module, which enables the brightness and color temperature of the first light strip 610 to be adjustable, thereby improving the user's comfort experience.

[0053] It is understood that the back panel 300 includes an outer frame 310 and an inner frame 320, which are arranged in a stepped manner. The inner frame 320 is located at the front end of the outer frame 310, such as... Figure 1As shown. The front end of the inner frame 320 is embedded in the cover plate 400, thereby connecting the back plate 300 and the cover plate 400 and further improving the stability of the connection between the back plate 300 and the cover plate 400. The outer frame 310, the inner frame 320 and the rear end of the cover plate 400 form a mounting groove on the outer side, that is, the first light strip 610 is arranged around the outer end face of the inner frame 320. The front end and the rear end of the first light strip 610 are respectively limited by the cover plate 400 and the outer frame 310 to prevent the first light strip 610 from moving back and forth.

[0054] It is understandable that, since the back plate 300 and the cover plate 400 are embedded and connected, the front inner end of the back plate 300 and the rear inner end of the cover plate 400 are connected and form an installation cavity.

[0055] It is understandable that the inner frame 320 has a groove 321, such as Figure 1 As shown. The groove 321 connects the mounting groove and the mounting cavity, which facilitates the electrical connection between the first light strip 610 and the circuit board 500, and the two ends of the first light strip 610 can be fastened into the groove 321, so that the first light strip 610 is stably connected to the back plate 300.

[0056] In some embodiments, the groove 321 is provided such that after the first light strip 610 surrounds the outer end face of the inner frame 320, its two ends are snapped into the groove 321.

[0057] In this embodiment, two grooves 321 are provided and are respectively located at the left and right ends of the inner frame 320, such as... Figure 1 As shown. Correspondingly, the first light strip 610 includes an upper light strip 611 and a lower light strip 612. The two ends of the upper light strip 611 are respectively fastened into two grooves 321, and the two ends of the lower light strip 612 are respectively fastened into two grooves 321, thereby realizing a simple and stable connection between the first light strip 610 and the back plate 300.

[0058] Understandably, the outer end face of the first light strip 610 is aligned with the outer end face of the cover plate 400 and the outer frame 310, respectively. Specifically, the outer end face of the first light strip 610 extends in the front-to-back direction, and the outer end face of the cover plate 400 and the outer frame 310 also extend in the front-to-back direction, making the outer end face of the extension panel 100 neat, flat and smooth, thus improving the aesthetics of the extension panel 100.

[0059] Understandably, a second LED strip 620 surrounds the conductive component 700. The second LED strip 620 indicates the position of the conductive component 700, allowing users to quickly and clearly see the specific location of each conductive component 700 in dim environments. Users can plug electrical appliances into the conductive components 700 to power them on without repeatedly turning the lights on and off. The second LED strip 620 is connected to the circuit board 500, enabling communication between the second LED strip 620 and the wiring component 800. The circuit board 500 can control the power supply to and from the second LED strip 620, thus controlling its on / off state.

[0060] In some embodiments, the conductive component 700 is connected to the front end face of the circuit board 500, and the cover plate 400 is provided with a mounting base 430 corresponding to the conductive component 700. When the cover plate 400 and the back plate 300 are connected, the front end of the conductive component 700 is embedded in the mounting base 430, providing sufficient support for the conductive component 700. Since the second light strip 620 surrounds the outside of the conductive component 700, the second light strip 620 is located on the front end face of the circuit board 500.

[0061] In this embodiment, the conductive component 700 is embedded within the circuit board 500, such as... Figure 1 As shown, this reduces the front and rear thickness of the mounting cavity, thereby reducing the volume of the expansion panel 100, lowering costs, and making the expansion panel 100 lighter. Correspondingly, the second light strip 620 is embedded in the circuit board 500, that is, the second light strip 620 is located between the circuit board 500 and the conductive component 700, making the position of the second light strip 620 more stable and facilitating the connection between the second light strip 620 and the circuit board 500.

[0062] Correspondingly, the cover plate 400 is provided with a light-transmitting hole 410 corresponding to the second light strip 620, such as Figure 1 and Figure 3 As shown, when the second light strip 620 is activated, the light emitted by the second light strip 620 located in the mounting cavity passes through the light-transmitting hole 410, allowing the user to see the light emitted by the second light strip 620 and thus determine the position of the conductive component 700. Each conductive component 700 is surrounded by the second light strip 620, that is, the cover plate 400 is provided with multiple light-transmitting holes 410 corresponding one-to-one with the multiple conductive components 700.

[0063] In this embodiment, three conductive components 700 are provided, such as... Figure 1 As shown. Correspondingly, the second light strip 620 has three lights, and the cover plate 400 has three light-transmitting holes 410.

[0064] It is understandable that each light-transmitting hole 410 is an annular hole formed by piecing together multiple arc segments, so that the position of the light-transmitting hole 410 does not interfere with the position of the plug of the electrical equipment.

[0065] It is understandable that the inner side of the light-transmitting hole 410 corresponds to the second light strip 620, and the outer side of the light-transmitting hole 410 corresponds to the light guide shell 900, such as... Figure 1 As shown. The light guide housing 900 is made of light guide material and is snap-fitted to the cover plate 400, facilitating assembly and disassembly of the light guide housing 900 and the cover plate 400. Therefore, the light guide housing 900 can cover the light-transmitting hole 410, preventing dust and other particles in the air from entering the mounting cavity through the light-transmitting hole 410 and affecting the service life of the conductive component 700 and the circuit board 500. The light guide housing 900 can also evenly diffuse the light transmitted through the light-transmitting hole 410 to the entire light direction of the light guide housing 900, further facilitating the user to plug and unplug electrical devices on the expansion panel 100. Moreover, the light emitted by the second light strip 620 is evenly distributed to the light guide housing 900 through the light-transmitting hole 410, providing a uniform and soft lighting effect for the conductive component 700.

[0066] It is understandable that the front end face of the cover plate 400 is recessed to form a connecting cavity 440, such as... Figure 1 and Figure 3 As shown, the snap-fit ​​connection between the light guide housing 900 and the cover plate 400 is actually a snap-fit ​​connection between the rear end of the light guide housing 900 and the cavity wall of the connecting cavity 440.

[0067] In some embodiments, the light guide housing 900 is fully embedded in the connection cavity 440, making the extension panel 100 thinner and lighter.

[0068] In other embodiments, the rear end of the light guide housing 900 is snapped into the connecting cavity 440, and the front end of the light guide housing 900 protrudes from the connecting cavity 440. When disassembling the light guide housing 900, the user can directly pull out the light guide housing 900 without tools.

[0069] It is understandable that the front end face of the conductive component 700 is provided with a conductive hole 710 for inserting a plug, such as Figure 1 As shown. The cover plate 400 has a first socket 450 for inserting a plug, and the first socket 450 is connected to the mounting base 430 at the front and rear, as shown. Figure 1 and Figure 3 As shown. The light guide housing 900 is provided with a second socket 910 for inserting a plug. The second socket 910 extends through the light guide housing 900 from front to back, as shown. Figure 1 and Figure 2 As shown, the conductive hole 710, the first socket 450, and the second socket 910 are arranged from back to front and are in a straight line opposite each other. When the plug of the electrical device is inserted into the extension panel 100, the plug passes through the second socket 910, the first socket 450, and the conductive hole 710 in sequence, thereby realizing power supply.

[0070] Understandably, the inner frame 320 has multiple snap-fit ​​slots along its edge, and the inner side of the cover plate 400 has multiple fasteners corresponding to the multiple snap-fit ​​slots. The connection between the cover plate 400 and the back plate 300 also includes the snap-fit ​​between the multiple fasteners and the multiple snap-fit ​​slots.

[0071] Understandably, the back plate 300 has mounting posts extending forward and backward on its inner side. The mounting posts are used to snap together with the circuit board 500, thereby fixing the circuit board 500 and the back plate 300 relatively. When the cover plate 400 is removed from the back plate 300, the circuit board 500 is stably connected to the back plate 300.

[0072] like Figure 1 As shown, the expansion socket of this utility model embodiment includes a base box 200 and an expansion panel 100 connected by screws. Specifically, the cover plate 400 is provided with a first mounting hole 420, the back plate 300 is provided with a second mounting hole, and the base box 200 is provided with a threaded connecting screw and a connecting screw hole 210. The connecting screw passes through the first mounting hole 420 and the second mounting hole from front to back and is then screwed into the connecting screw hole 210, thereby connecting and fixing the cover plate 400, the back plate 300 and the base box 200, achieving a stable connection between the base box 200 and the expansion panel 100, and preventing the expansion panel 100 from loosening and falling off.

[0073] Understandably, the circuit board 500 has holes for avoiding the connecting bolts.

[0074] Meanwhile, since the back plate 300 and the cover plate 400 are connected by a snap-fit ​​groove and a fastener, the cover plate 400 remains stably connected to the back plate 300 when the connecting screws are loosened, thus preventing the cover plate 400 from falling off.

[0075] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
