[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 As shown, an embodiment of this utility model provides a one-button self-rescue system for a villa elevator, including a one-button rescue button 1, a relay shorting board 2, a control cabinet interface board 3, and a control cabinet main board 4. The one-button rescue button 1 is located inside the elevator car. Specifically, the one-button rescue button 1 can be installed on the elevator instruction board 5. The elevator instruction board 5 is communicatively connected to the car top interface board 6, and the car top interface board 6 is communicatively connected to the control cabinet interface board 3.

[0021] The main board 4 of the control cabinet is connected to the interface board 3 of the control cabinet. The interface board 3 of the control cabinet is equipped with interfaces such as door lock circuit interface, safety circuit interface, control cabinet emergency stop interface, one-button rescue signal output interface, safety relay signal feedback interface, first power interface, and second power interface, which are used to connect the corresponding circuits.

[0022] The relay shorting board 2 is equipped with relays K1 and K2, as well as multiple parallel shorting circuits. Both relays K1 and K2 include a relay coil, a normally open contact, and a normally closed contact. The multiple shorting circuits are connected to the end of the door lock circuit, the end of the safety circuit, and the end of the emergency stop circuit of the control cabinet through corresponding interfaces on the control cabinet interface board 3. The normally open contacts (3, 4) of relay K1 are connected in series with the shorting circuit at the end of the emergency stop circuit of the control cabinet, while the normally open contacts (7, 8) of relay K2 are connected in series with the shorting circuit at the end of the door lock circuit.

[0023] The relay coils of relays K1 and K2 are connected in parallel. One end of each relay coil and the safety relay signal feedback interface are connected to the first power interface. The normally closed contacts (1, 2) and (5, 6) of relays K1 and K2 are connected in series between the safety relay signal feedback interface and the first power interface. The other end of each relay coil and the one-button rescue signal output interface are connected to the second power interface. A normally open contact KM5 is connected in series between the second power interface, the relay coils, and the one-button rescue signal output interface. The normally open and normally closed contacts of relays K1 and K2 are triggered and controlled by the normally open contact KM5, which is triggered and controlled by the one-button rescue button 1.

[0024] Specifically, when the elevator is running normally, if no one triggers the one-button rescue button 1, the system will not send a one-button rescue signal. The normally open contact of KM5 on the control cabinet interface board 3 will be open, and the relay coils of relays K1 and K2 on the relay shorting board 2 will not be energized. The normally closed contact (1,2) of relay K1 will be closed and the normally open contact (3,4) will be open. The normally closed contact (5,6) of relay K2 will be closed and the normally open contact (7,8) will be open. The safety circuit and the door lock circuit (110, 130, 134) will not be short-circuited. The safety relay contacts will provide feedback signals, and the elevator will run normally. When the elevator is trapped in a non-door zone safety circuit or due to a door lock malfunction, the passenger inside the car presses and holds the one-button rescue button 1. The system receives the one-button rescue signal and enters self-rescue mode. The normally open contact of KM5 on the control cabinet interface board 3 closes, and the relay coils of relays K1 and K2 on the relay shorting board 2 are energized. The normally closed contact (1,2) of relay K1 opens and the normally open contact (3,4) closes. The normally closed contact (5,6) of relay K2 opens and the normally open contact (7,8) closes. The safety circuit and the door lock circuit (110, 130, 134) are short-circuited, the fault is automatically reset, and the elevator moves to the nearest level and opens the door to release the passenger. When the elevator door opens and the passenger releases the one-button rescue button 1, relays K1 and K2 are de-energized. The normally open contacts (3,4) of relay K1 and (7,8) of relay K2 are opened again. The safety circuit and the door lock circuit are no longer short-circuited, the elevator malfunctions, and stops running.

The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
