[0002] At present, the elevators installed in the known multi-storey buildings are all pulled by wire ropes, which have the disadvantage that the higher the elevator operation height is, the heavier the weight of the wire rope pulling the car is when it is at the bottom. Summary of the invention

[0019] The working process of this utility model:
[0020] The supercapacitor 501 is installed at the bottom of the car 300, and the first movable contact 511 is connected to the positive electrode of the supercapacitor 501 by an electric wire; the second movable contact 512 is connected to the negative electrode of the supercapacitor 501 by an electric wire; the first fixed contact 523 is installed on the first elastic bracket 525, and the first elastic bracket 525 is installed on the elevator passage wall 500 but insulated from the elevator passage wall 500, and the first fixed contact 523 is connected to the positive electrode of the external power supply 502; the second fixed contact 524 is installed on the second elastic bracket 526, and the second elastic bracket 526 is installed on the elevator passage wall 500 but insulated from the elevator passage wall 500, and the second fixed contact 524 is connected to the negative electrode of the external power supply 502. After the car system 200 arrives at the designated floor and stops normally, when the left second car door of the car 300 is in the closed state, the first movable contact 511 and the first fixed contact 523 are in a non-contact state, and at the same time, the second movable contact 512 and the second fixed contact 524 are also in a non-contact state.
[0021] Then, in action 1, when the two car doors are opened at the same time: the first movable contact 511 installed on the first car door 510 gradually approaches the first fixed contact 523 as the first car door 510 moves outward, and as the first car door 510 continues to move outward, the first movable contact inclined surface 515 of the first movable contact 511 contacts the non-conductive inclined surface 517 of the first fixed contact, and then, under the action of these two inclined surfaces, the first fixed contact 523 compresses the elastic material of the first elastic bracket 525, so that the first movable contact contact surface 513 slides toward the sliding variable resistor Contact surface 519, at this time, the first movable contact 511 is connected to the first fixed contact 523, because the resistance value of the sliding variable resistor contact surface 519 is relatively large at this time; as the first movable contact 511 continues to move outward, the resistance value between the first movable contact contact surface 513 and the sliding variable resistor contact surface 519 becomes smaller and smaller, until the first movable contact contact surface 513 contacts the first fixed contact contact surface 521, and the contact resistance value is close to zero at this time, and the first elastic bracket 525 can keep the first movable contact contact surface 513 and the first fixed contact contact surface 521 in relatively close contact. At the same time, the second movable contact 512 installed on the second car door 520 gradually approaches the second fixed contact 524 as the second car door 520 moves outward. As the second car door 520 continues to move outward, the second movable contact inclined surface 516 first contacts the second fixed contact inclined surface 518. At this time, the second movable contact 512 is connected and conducted with the first fixed contact 524. Then, under the action of the two inclined surfaces, the second fixed contact 524 compresses the elastic material of the second elastic bracket 526, so that the second movable contact contact surface 514 slides toward the second fixed contact contact surface 522. The second elastic bracket 526 can keep the second movable contact contact surface 514 and the second fixed contact contact surface 522 in a relatively close contact. During the contact between the first movable contact inclined surface 515 and the first fixed contact non-conductive inclined surface 517, the contact between the second movable contact inclined surface 516 and the second fixed contact inclined surface 518 is also achieved. After the first movable contact surface 513 contacts the sliding variable resistor contact surface 519, the current that the external power source 502 can charge the supercapacitor 501 becomes larger and larger; after the first movable contact surface 513 contacts the first fixed contact surface 521, the current that the external power source 502 can charge the supercapacitor 501 is the largest.
[0022] Then, action 2 is performed. When the two car doors are closed, the first movable contact 511 installed on the first car door 510 moves inward with the first car door 510, until the first movable contact surface 513 is out of contact with the first fixed contact surface 521. As the first movable contact 511 continues to move inward, the resistance value passing through the sliding variable resistor contact 519 becomes larger and larger, and the current that the external power supply 502 can charge the supercapacitor 501 becomes smaller and smaller; when the first movable contact slope 515 is in contact with the first fixed contact non-conductive slope 517, the resistance tends to infinity, and the circuit for the external power supply 502 to charge the supercapacitor 501 is in a cut-off and non-powered state; as the two car doors are closed, the first movable contact slope 515 is out of contact with the first fixed contact non-conductive slope 517, and the circuit for the external power supply 502 to charge the supercapacitor 501 is in a disconnected and non-conductive state. At the same time, after the second movable contact 512 on the second car door 520 moves inward with the second car door 520, as the two car doors close, the second movable contact 512 is disengaged from the second fixed contact 524, and the circuit for the external power supply 502 to charge the supercapacitor 501 is in an open circuit and non-conducting state.
