The integrated device also includes a control system, and the telescopic device 2 receives instructions from the control system to extend and/or retract. In one embodiment, the telescopic device 2 is a push-pull electromagnet, which retracts when powered on and resets when powered off. When the telescopic device 2 is extended, the locking rod 3 is inserted into the card slot, the door is locked, and the power supply device 9 contacts the receiving device 10 to form a power supply circuit to supply power to the electrical equipment on the safety door.

In one embodiment, the power supply device 9 includes an insulating plate 9a, a positive power supply electrode 9b, and a negative power supply electrode 9c; the receiving device includes a receiving end mounting plate 10a, an insulator 10b, a positive receiving electrode 10c, and a negative receiving electrode 10d; the positive power supply electrode 9b, the negative power supply electrode 9c, the positive receiving electrode 10c, and the negative receiving electrode 10d include spring electrodes and/or copper blocks, which conduct the power supply circuit when in contact. For example, the positive power supply electrode 9b and the negative power supply electrode 9c are both composed of two spring electrodes connected by copper plates, one of which is a redundant design. The positive receiving electrode 10c and the negative receiving electrode 10d are copper blocks, and the power supply circuit can be conducted when the spring electrodes are in contact with the copper blocks.

In another embodiment, the safety door is coated with a flexible thin-film solar cell, and the solar cell has a transparent protective layer.

Example 2

Illustratively, in one embodiment, ultra-thin and ultra-light organic thin film solar cells are used and directly coated on the surface of the door leaf. Thin film solar cells use organic materials to absorb visible light to generate electricity, and the organic materials are usually composed of conductive polymers or quantum dots. The core components include an ultra-thin organic photoelectric active layer, a transparent conductive electrode layer, and a sealing layer. This flexible structure allows it to be bent without damage. This thin film solar cell is only a few microns thick and extremely light. It can be bent at will without damage, and can absorb the visible spectrum to generate electricity. The door leaf material uses a resin or glass material with high light transmittance to ensure sufficient light transmission. The electricity generated by the battery is stored in a small polymer lithium-ion battery.

The safety door slot 11 and the locking rod 3 are relatively positioned through the gap sensor, including: the horizontal door frame of the safety door has a slope design, and the gap sensor is set 1.5m near the closing point and is level with the horizontal door frame. When the safety door runs to the vicinity of the closing point, the gap sensor detects the vertical distance from the door frame, and accurately measures the position of the safety door according to the distance. The control system adjusts the running speed of the safety door based on the information of the gap sensor, so that its parking position is within the error range of ±1mm of the closing point, and realizes the precise coordination between the safety door slot 11 and the locking rod 3, and/or the power supply device 9 and the receiving device 10.

As shown in FIG3 , under the initial condition, the telescopic device 2 loses power and is in a reset state, the spring electrode of the positive power supply electrode 9b contacts the copper block of the positive receiving electrode 10c, and the spring electrode of the negative power supply electrode 9c contacts the copper block of the negative receiving electrode 10d, turning on the power supply circuit, and supplying power to the electrical equipment on the safety door through solar cells, small polymer lithium-ion batteries, etc. At the same time, the locking rod 3 is inserted into the card slot 11 to lock the safety door, and the first sensor 5 is blocked by the sensor trigger board 4 and the locking state is uploaded to the control system.

When the safety door needs to be opened, the control system controls the telescopic device 2 to contract, driving the locking rod 3, the power supply device 9, and the sensor trigger plate 4 to move together, and the locking rod 3 leaves the card slot 11 and unlocks the safety door. At the same time, the spring electrode is disconnected from the copper block and the power supply is disconnected, and the second sensor 6 is blocked by the sensor trigger plate 4 and the unlocking state is uploaded to the control system. At this time, the organic thin film solar cell charges the small polymer lithium-ion battery.

When the safety door is fully closed, the control system controls the telescopic device 2 to lose power and reset to the initial state. At this time, the spring electrode contacts the copper block again, and the power supply to the safety door is restored. At the same time, the locking rod 3 is inserted into the card slot 11 to lock the safety door. The first sensor 5 is blocked by the sensor trigger plate 4 and the locking state is uploaded to the control system, completing the process monitoring and control closed loop. At this time, the small polymer lithium-ion battery can be charged and discharged, such as releasing the stored electrical energy to power the safety door, or the external power supply powers the safety door and charges the solid-state and/or liquid battery, such as a lithium-ion battery.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
