Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, specifically to a socket with a multi-functional interface. Background Technology
[0002] Traditional power strips only provide AC power outlets, which cannot meet the direct charging needs of devices such as mobile phones, tablets, and laptops. Although smart power strips with integrated USB interfaces have emerged, reducing reliance on charging adapters to some extent, their interface types are fixed and cannot be adapted to different signal or power interfaces such as HDMI, Type-C, and DC power, resulting in poor expandability and difficulty in meeting the needs of multiple devices and multiple scenarios.
[0003] Furthermore, existing sockets generally lack intelligent management functions, failing to monitor the current, voltage, and power status of each interface in real time, posing safety hazards such as overload and short circuits. While some smart sockets offer remote control or timed on / off functions, they mostly rely on Wi-Fi modules, lacking proactive load sensing and protection capabilities, and their interface layout is limited and cannot be dynamically adjusted according to user needs.
[0004] In terms of structural design, once a traditional socket is manufactured, its interface configuration cannot be changed. If a specific functional interface needs to be added, an adapter must be provided or the entire unit must be replaced, resulting in a waste of resources. At the same time, sockets are difficult to position at night, affecting ease of operation and safety. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 The present invention relates to a socket with a multi-functional interface, comprising:
[0029] The socket body 1 has a control circuit board inside it;
[0030] A fixed interface group is embedded in the front of the socket body 1, including at least two power sockets 2 and three USB interfaces 3;
[0031] A replaceable interface module is provided. The socket body 1 has a slot 4 on its side. The replaceable interface module is detachably connected to the slot 4 through a buckle 16 structure 10.
[0032] The intelligent main control module is installed on the control circuit board and includes an MCU chip, a relay, a current sensor, a voltage sensor, and a wireless communication unit. The MCU chip is electrically connected to the current sensor, voltage sensor, relay, and wireless communication unit. The current sensor and voltage sensor are connected in parallel to a fixed interface group and a replaceable interface module, respectively. The relay is connected in parallel to the fixed interface group and the replaceable interface module.
[0033] This technical solution achieves flexible adaptation and safe intelligent management of electrical equipment through a collaborative mechanism of fixed interfaces, replaceable modules, and intelligent control. Its overall working principle is as follows: After the socket body 1 is connected to mains power, the electrical energy is distributed to the fixed interface group and the replaceable interface module via the control circuit board; the MCU chip of the intelligent main control module acts as the core, monitoring the power parameters of each interface in real time, such as current, voltage, and power, through current and voltage sensors; when a device is inserted into an interface, the MCU chip controls the relay to close based on the monitoring data, supplying power to each interface; users can install or remove expansion interfaces such as HDMI and Type-C as needed through the snap-fit structure 10 of the replaceable interface module (16). The module and socket are electrically connected via gold-plated probes 6 and conductive sheets 11; the wireless communication unit supports remote connection to mobile devices via WiFi / Bluetooth, such as a mobile APP, to switch interfaces on and off or check power status; the ambient light sensor 13 senses light intensity, and the MCU chip controls the LED night light 12 to automatically turn on and off. Through the above mechanism, the integrated functions of basic power supply, flexible expansion, and intelligent protection are achieved.
[0034] V-shaped elastic lever, 15 buckles, 16 structure, 10.
[0035] The snap-fit structure 10 is the core component that enables quick installation and removal of the replaceable interface module. Its working principle is as follows:
[0036] Fixed Module: The V-shaped elastic levers 15 on both sides of the replaceable interface module have natural elasticity and are made of spring steel or high-strength plastic. When inserted into the slot 4, the V-shaped levers are deformed under pressure. When the conductive port 14 at the bottom of the module contacts the gold-plated probe 6 in the slot 4, the buckle 16 on one side of the lever aligns with the slot 5 on the inner wall of the slot 4. The levers elastically reset so that the buckle 16 is embedded in the slot 5, thus achieving mechanical fixation of the module.
[0037] Disassembling the module: Move the lever 17 at the top of the V-shaped lever. External force causes the lever to overcome elastic deformation, and the buckle 16 disengages from the slot 5. At this time, the module can be easily pulled out to complete the replacement.
[0038] Replaceable interface modules, such as HDMI port 9, Type-C port 8, and power port 7.
[0039] The replaceable interface module enables functional expansion through standardized mechanical and electrical interfaces. Its working principle is as follows:
[0040] HDMI Interface 9 Module: It integrates the HDMI signal transmission circuit. The bottom conductive plate 11 is connected to the power and signal bus of the socket. After insertion, it can obtain power and transmit audio and video signals through the gold-plated probe 6. It supports specifications such as 4K / 60Hz and is compatible with TVs, projectors and other devices.
[0041] Type-C interface 8 module: Supports dual functions of data transmission and charging. Conductive plate 11 contains data cable and power cable of USB 3.1 protocol. After insertion, MCU chip recognizes module type and automatically matches 5V / 3A or 100W PD fast charging protocol.
[0042] Power Interface 7 Module: Built-in voltage regulation circuit, which can switch between 5V / 12V / 24V output via DIP switch on the side of the module. Conductive plate 11 connects to the low-voltage DC power supply after AC power conversion, and is compatible with devices such as routers and surveillance cameras.
[0043] Electrical connection between gold-plated probe 6 and conductive port 14 / conductive sheet 11
[0044] This structure ensures reliable electrical conductivity between the replaceable module and the socket body 1. Its working principle is as follows:
[0045] Low resistance conduction: The gold-plated probe 6 (gold plating thickness ≥ 5μm) in the slot 4 has excellent conductivity and corrosion resistance. When it contacts the conductive port 14 at the bottom of the replaceable module, the probe is embedded in the conductive port 14 and elastically presses against the conductive sheet 11 to avoid heat generation caused by poor contact.
[0046] Flame-retardant insulating shell
[0047] The socket body 1 is made of flame-retardant insulating material, such as PC+ABS alloy, with a flame-retardant rating of UL94V0. Its working principle is as follows:
[0048] Insulation protection: Casing resistance ≥10 12 Ω can block direct contact between mains electricity and the human body, preventing electric shock accidents;
[0049] Flame retardant and fireproof: When exposed to high temperatures, such as when an internal short circuit causes a fire, the material is not easily ignited and self-extinguishes after burning, preventing the spread of flames and thus improving safety.
[0050] Ambient light sensor 13 and LED night light 12
[0051] This component enables automatic nighttime lighting, and its working principle is as follows:
[0052] Light detection: Ambient light sensor 13, such as a photoresistor or digital light sensor, collects the ambient light intensity in real time and converts the analog signal into an electrical signal to be transmitted to the MCU chip;
[0053] Intelligent control: The MCU chip presets a threshold, such as ≤10 lux, which is considered a dark environment. When the detected value is lower than the threshold, the control relay closes and the LED night light 12 is lit; when the light increases to ≥50 lux, the relay opens and the night light is turned off.
[0054] Detailed Workflow
[0055] System initialization
[0056] When the socket is connected to AC220V mains power, the control circuit board starts working, and the intelligent main control module performs a power-on self-test.
[0057] MCU chip initialization, checking whether current sensor, voltage sensor, relay, and wireless communication unit are normal;
[0058] The relay is initially open, and neither the fixed interface group nor the replaceable interface module is powered.
[0059] Ambient light sensor 13 starts collecting light data, and LED night light 12 is off by default.
[0060] Replaceable interface module installation and identification
[0061] Module installation: The user selects the interface module according to the device requirements, such as HDMI, pinches the levers 17 on both sides of the module to retract the buckles 16 of the V-shaped elastic levers 15, and inserts the module into the slot 4 on the side of the socket; when the conductive port 14 at the bottom of the module contacts the gold-plated probe 6 in the slot 4, the levers 17 are released, the V-shaped levers are reset, and the buckles 16 are inserted into the slots 5 to complete the fixation.
[0062] Module identification: After the gold-plated probe 6 contacts the conductive plate 11 of the module, the MCU chip detects the specific pin signals of the conductive plate 11. Different modules have different signal codes, so the MCU chip identifies the module type, such as "HDMI" or "Type-C", and marks the function of the interface in the internal system.
[0063] Equipment access and power supply control
[0064] Fixed interface group usage: When the user plugs the device into the fixed interface group, such as USB interface 3, the current sensor and voltage sensor immediately detect the load connection and transmit the current (I) and voltage (U) data to the MCU chip. The MCU calculates the power (P = U × I). If it does not exceed the safety threshold, such as USB interface 3 ≤ 10W, it controls the corresponding interface relay to close and power the device.
[0065] Replaceable module usage: Taking HDMI interface 9 as an example, the user connects the device and the module with an HDMI cable. The MCU chip detects the load signal through the gold-plated probe 6, identifies it as a data or power supply requirement, controls the relay of the module to close, and at the same time uploads the enabled status of HDMI interface 9 to the mobile APP through the wireless communication unit.
[0066] Intelligent control and condition monitoring
[0067] Remote control: Users can send commands via a mobile app, such as turning off Type-C interface 8. The wireless communication unit receives the command and transmits it to the MCU chip. The MCU then controls the corresponding relay to disconnect and stop the power supply.
[0068] LED Night Light 12 Automatic Control: Ambient light sensor 13 collects light intensity every 10 seconds. If the detected ambient light is ≤10 lux, the MCU chip controls the relay of LED Night Light 12 to close, and the night light turns on; when the light is ≥50 lux, the relay opens, and the night light turns off.
[0069] Power consumption monitoring: Current / voltage sensors monitor the power consumption parameters of each interface in real time, and the MCU chip records the cumulative power consumption and real-time power, which is synchronized to the APP through the wireless communication unit for users to view.
[0070] Anomaly protection and module replacement
[0071] Overload protection: When the power of a certain interface exceeds the safety threshold, such as power interface 7 ≥ 240W, the current sensor triggers an overcurrent signal, and the MCU chip controls the corresponding relay to disconnect within 0.5 seconds to stop the power supply and push an overload alarm through the APP.
[0072] Module replacement: When the user needs to replace the interface, turn off the power supply to the corresponding module in the APP, or operate directly by pinching the module lever 17 to disengage the clip 16 from the slot 5 and pull out the old module; install the new module according to step 2, and the MCU chip will re-identify and enable the new module.
[0073] System shutdown
[0074] After the device is removed, the current sensor detects zero load, and the MCU chip controls the relay to disconnect after a 30-second delay.
[0075] After the mains power is disconnected, the system stops working and all relays are reset to the open state.
[0076] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
