Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1-7.

A multifunctional slide-type safety portable socket with a plug bracket, which includes a housing 1, a fixed socket body 2 and a control circuit are installed in the upper layer of the housing 1, and a pullable socket body is installed in the lower layer of the housing 2. Out of the sliding socket body 3, the fixed socket body 2 on the upper layer is electrically connected to the sliding socket body 3 on the lower layer. A sliding pin can be arranged on the sliding socket body 3, and the sliding pin contacts the conductive sheet at the bottom of the fixed socket body 2 to design the upper and lower The electrical connection of the layer, the lower part of the fixed socket body 2 near the position of the insertion port and the upper front end of the sliding socket body 3 are provided with an anti-prolapse structure. There is a hanging structure 5 for hanging the plug so as to facilitate the storage of the plug. The hanging structure 5 is composed of upwardly protruding symmetrical ribs 6, and the two ribs 6 form a wire channel 7, as shown in Figures 1 and 2. The composition of the control circuit of the utility model is shown in Fig. 3 . Its connection relationship is that the power input end of the fixed socket body 2 is connected with an infrared remote control receiving circuit capable of controlling power on and off (as shown in Figure 5), and the infrared remote control receiving circuit is wirelessly connected with the infrared transmitting circuit in the infrared remote control (as shown in Figure 6 ), the structure of the infrared receiving head installed in the fixed socket body 2 is shown in Figure 7, and a USB charging circuit is connected to the circuit output end of the fixed socket body 2 (as shown in Figure 4), and the output of the USB charging circuit and the sliding The USB jack 4 of the socket body 3 is connected. The power input end of the fixed socket body 2 is also connected to a current-limiting and temperature-limiting cut-off circuit.

The details are as follows:

1. Appearance design.

The overall structure of the socket of the utility model is the same as a sliding cover mobile phone, which is divided into upper and lower parts, which can slide in parallel with each other, and the upper tail is connected and fixed with the lower front to prevent falling off.

The sliding cover design makes the socket more compact and fashionable. In the case of less electrical appliances, the user only needs to directly use the jack on the upper surface of the socket. In the case of many electrical appliances, the lower jack can be pulled out to meet the needs of users.

The addition of a hanging structure facilitates the storage of the plug. Because after the remote control shutdown, some circuits of many electrical products are still in the working state, waiting to receive the remote control start signal, thus increasing the power consumption. If the plug is unplugged, there will be no power consumption, so adding this hanging structure is conducive to energy saving and consumption reduction.

2. Increase the universal charger interface Micro-USB.

At the Mobile World Congress in 2009, the Global System for Mobile Communications Association (GSMA) and OTMP initiated the formulation of an international unified standard for mobile phone chargers. At present, the charger interfaces of most mobile phones and cameras also use the Micro-USB interface.

In the utility model, a Micro-USB interface 4 is designed on the side of the lower socket (or on the upper layer), which can not only be used as a mobile phone charger interface, but also meet the power supply requirements of other small household appliances. The internal circuit is composed of transformers, diodes, ceramic capacitors, etc. Convert 220V AC power into a stable 5V DC power, which is convenient for charging electronic products such as mobile phones and cameras. In addition, the use of the socket with the addition of a universal interface can reduce standby energy consumption, reduce the use of redundant chargers, reduce greenhouse gas emissions, and save consumers a sum of purchase costs.

3. Adopt infrared remote control technology.

An infrared remote control system is set inside the socket to realize the remote control of the socket. Since various manufacturers have produced infrared remote control application-specific integrated circuits, it is now very convenient to realize the remote control of electrical appliances. In addition, through the on-off of the infrared remote control socket, no button on the socket can be provided, saving materials.

The main function is to control the power on and off of the socket through infrared remote control to realize the control of whether the electrical appliance is working. It is convenient for users to operate, and at the same time cut off the power supply of electrical appliances, which can reduce standby power consumption and save electric energy.

In addition, a safety circuit can also be set to prevent current overload, excessive power, and circuit instability, etc., to protect electrical appliances.

The circuit of the whole socket includes a safety circuit, an infrared remote control circuit, a charger circuit and an ordinary socket circuit. Wherein the charger circuit is located in the lower sliding cover of the sliding cover socket or in the upper fixed socket, and the remaining circuits are located in the upper fixed socket body.

As shown in Figure 4, the USB charging circuit uses 220V AC to output a stable 5V DC current through transformation, rectification, filtering, and voltage stabilization. The DC power supply is connected to the two pins of VCC and GND of the Micro-USB interface, so that the USB cable can be connected to charge electronic products such as mobile phones (the other two pins of the USB do not need to be used).

As shown in Figure 5, it is the schematic diagram of the infrared remote control circuit. The circuit is mainly composed of an infrared transmitting circuit, an infrared receiving circuit, a switch circuit and a power supply circuit.

The infrared emitting circuit is composed of a command key, a signal generator, a modulation circuit, a driving circuit, and an infrared emitting device, as shown in Figure 6. When the command key is pressed, the required control command signal will be generated, modulated by the modulation circuit, and finally the drive circuit will drive the infrared emitting device to send out an infrared remote control signal (the remote control on the market has already adopted this technology).

The infrared receiving circuit adopts the HS0038B infrared receiving head, as shown in Figure 7. It is mainly composed of a photodiode and an infrared receiving IC. The working principle is that when the photodiode (commonly known as the receiving tube) receives the optical signal emitted by the infrared emitting tube and converts it into an electrical signal (a microampere current), the electrical signal is input into the receiving IC and amplified -- gain -- After filtering--demodulation--reshaping and restoration, restore the original code given by the remote control, and input it to the following circuit through the receiver signal OUT pin.

The main device of the switching circuit is the relay. Output high and low levels through the OUT pin to control the work of the executive circuit. When the input is high, the switch of the relay will change from one state to another. If you want to disconnect the socket in the power-on state, press the infrared transmitter remote control, the OUT pin will output a high level, and the normally closed switch of the relay will become a normally open switch; if you want to start the socket, press the infrared remote control device, the OUT pin will output a high level, and the normally open switch of the relay will become a normally closed switch. When the input is low, the relay switch does not work.

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
