[0046] As a further improvement, a power cord reel 26 is provided at the rear end of the storage slot 21, a power cord 261 is connected to the front of the power cord reel 26 via a coil spring, and the front of the power cord 261 is electrically connected to the power display screen 2;

[0047] The power cord reel device 26 allows the power cord 261 to automatically extend when the display screen is unfolded and automatically reel in when retracted, avoiding the power cord 261 from being messy. This is both beautiful and practical. At the same time, this design also reduces the risk of damage to the power cord 261 due to long-term dragging.

[0048] As a further improvement, the storage slot 21 is provided with limiting slots 212 on both sides of the front of the storage slot 21, and a reel 31 is provided above the limiting slot 212. The two sides of the reel 31 are rotatably connected with shaft plates 33, and the outside of the reel 31 is wound and connected with the curtain 3.

[0049] The limiting groove 212 is used for limiting the upward and downward movement adjustment of the magnetic suction plate 32, the reel 31 is used for winding or unwinding the curtain 3, and the shaft plate 33 is used for movably supporting the rotation of the curtain 3. Through the design of the curtain 3, the power display screen 2 can be blocked when it is not in use.

[0050] Specifically, a magnetic plate 32 is fixedly provided at the end of the curtain 3, and both ends of the magnetic plate 32 are embedded in the inner part of the limiting groove 212. One side of the reel 31 passes through the shaft plate 33 and is connected to a driving motor 34.

[0051] The metal structure is located below the limit groove 212, which is used to fasten and adsorb the magnetic plate 32, and has good dust and water proof effects. The magnetic plate 32 is embedded in the limit groove 212 to make the up and down adjustment more stable and avoid displacement. The drive motor 34 is used to drive the control roller 31 to rotate in forward and reverse directions.

[0052] Working principle: The infrared proximity sensor 22 is composed of an infrared transmitting module, an infrared receiving module, a resistor, an LED lamp, a buzzer, a transistor and a power module;

[0053] When a human body approaches, the sound and light alarm device 221 emits a buzzer sound and flashes the light, and at the same time, the power supply is started to control the electric push rod device 23, and the electric push rod device 23 automatically controls the push rod 231 to extend, and the universal ball 232, the shaft cylinder 233, the support plate 234 and the rotating shaft rod 235 are adjusted to make the power display screen 2 extend outward;

[0054] Then the electric hydraulic device 24 is started to automatically control the hydraulic rod 241 to retract, and the fixed block 242, the second shaft cylinder 243, the second support plate 244 and the second rotating shaft rod 245 are adjusted so that the power display screen 2 is turned downward as a whole, and the user can directly view the specific value of the power display screen 2;

[0055] After the observation is finished, when the human body leaves the infrared proximity sensing device 22, the electric push rod device 23 and the electric hydraulic device 24 automatically control the push rod 231 and the hydraulic rod 241 to return to their positions, and the power display screen 2 moves inward and is limited to the position in front of the metal frame partition 211. The distance between the limit groove 212 and the metal frame partition 211 is greater than the thickness of the power display screen 2.

[0056] At the same time, the driving motor 34 is started to automatically control the reel 31 to rotate in the forward direction, and the curtain 3 and the magnetic plate 32 are released downward along the limiting groove 212, completely covering the front of the power display screen 2 to prevent dust and water.

[0057] The infrared proximity sensor device 22 has a model number of E18-D10NK80NK, also known as an infrared control switch or a pyroelectric infrared sensor switch, which is an electronic device that uses infrared rays for non-contact control, and can detect whether an object appears in a specified area, and quickly switch the on and off state of the circuit according to the detection result;

[0058] The infrared receiving module includes an infrared receiving transistor, a filter, an amplifier and a signal processing circuit. The infrared receiving transistor can receive infrared signals in the environment, including infrared rays emitted by the transmitter and possibly reflected by other objects (such as the human body).

[0059] The received infrared signal is first converted into an electrical signal and input into the filter. The function of the filter is to filter out interference signals of other frequencies and retain only infrared signals of specific frequencies. The filtered signal will be amplified by the amplifier to improve the signal strength and clarity. Subsequently, the signal enters the signal processing circuit for processing to determine whether an object has entered the sensing area.

[0060] When an object (such as a human body) enters the sensing area, the object will reflect or block the infrared signal, causing the signal received by the receiver to change. The signal processing circuit will detect this change and determine whether there is an object approaching. Once it is confirmed that an object is approaching, the signal processing circuit will output a control signal to close or open the switch through the circuit control module.

The problem solved by the present invention is that the existing electric energy meter has low intelligent performance and a high installation height. Users need to use tools to stand high to view the specific value of the power consumption, and the display screen is exposed to the outside and is easily impacted and The present invention combines the above components with each other, integrates an infrared proximity sensing device to intelligently sense the approach of the user, and triggers the automatic pop-up opening of the power display screen, so that the user can directly observe the display screen value, which solves the problem that the existing electric energy meter is installed too high and is inconvenient to view. It does not require manual operation, improves the convenience of use and user experience, and is combined with the sound and light alarm device to remind, thereby enhancing safety and practicality; the power display screen is installed in the storage slot through a telescopic component, which not only reduces the direct impact and damage risk of external factors on the power display screen, but also enables the power display screen to be effectively protected when not in use. The telescopic component adopts an electric push rod device, an electric hydraulic device and other components to achieve flexible connection with the power display screen, ensuring the flexibility, stability and accuracy of the display screen during extension and retraction; the appearance of the entire electric energy meter body is more neat and beautiful, which meets the aesthetic requirements of modern home or office environment, and provides users with a more convenient, safe and comfortable electricity experience.
