[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] An embodiment of the present invention provides a villa elevator.

[0035] The villa elevator of this embodiment includes: a power supply, a car, a shaft and a rescue system. The villa elevator is equipped with the necessary structures of an elevator, such as a power system, a main engine brake, a door machine, a guide rail, etc. Among them, the car is driven by the power system to move up and down along the guide rail in the shaft, the main engine brake clamps the main engine driving wheel to achieve braking during the operation of the car, and the door machine is used to control the opening or closing of the car door. The power supply serves as a backup power supply to power the power system, the main engine brake, the door machine, etc.

[0036] like Figure 1 As shown, the rescue system is used to provide rescue when a villa elevator fails, fully ensuring the personal safety of passengers. The rescue system 100 includes: a trigger device 10, a control device 20 and a rescue door opening device 30. It should be noted that the electronic devices involved in the rescue system 100 (trigger button, self-rescue contactor, self-rescue in place contactor, brake release delay relay, etc.) are all existing finished products.

[0037] The trigger device 10 is used to control the start of the rescue system. In one embodiment, the trigger device 10 includes: a first trigger button 11 and a second trigger button 12. At this time, the rescue system is configured to start working when the first trigger button 11 and the second trigger button 12 are pressed simultaneously. The method of starting the rescue system with two trigger buttons is conducive to avoiding erroneous operation by passengers.

[0038] Mate Reference Figure 2 As shown, in order to facilitate the operation of passengers, the trigger device 10 is embedded in the inner wall of the car and is closed by a cover plate 13 pivotally connected to the inner wall of the car. In this way, when the villa elevator fails and needs rescue, the passenger opens the above cover plate and presses the first trigger button 11 and the second trigger button 12 at the same time to trigger the rescue system to start working.

[0039] The control device 20 is used to realize the self-rescue downward movement of the car, that is, when the car is powered by a backup power supply, the main engine brake performs a release action and the car gradually descends to the bottom of the shaft driven by the power system.

[0040] The control device 20 includes: a self-rescue contactor 21 , a self-rescue in-position contactor 22 and a brake release delay relay 23 .

[0041] The trigger device 10 is connected to the brake release delay relay 23 via the self-rescue contactor 21. Specifically, the first trigger button 11 is connected to the self-rescue contactor 21, and the second trigger button 12 is connected to the brake controller. The self-rescue contactor 21 can be used to feedback the brake release signal, and the brake release delay relay 23 can be used to feedback the brake release delay signal.

[0042] In this way, when the passenger presses the first trigger button 11, the self-rescue contactor 21 is activated, which controls the main engine brake to supply power and releases the brake to realize the self-rescue downward movement of the car. At the same time, the system controls the elevator to forcibly enter the star-sealing state and controls the elevator to forcibly enter the maintenance state. In addition, the brake release delay relay 23 works with the action of the self-rescue contactor 21, and this brake release delay relay 23 controls the delayed start of the electric brake release device. Among them, the electric brake release device is a device that drives the main engine brake to open. This setting is to prepare for subsequent voice prompts to avoid the sudden start of the car self-rescue downward movement, causing panic to passengers.

[0043] The induction switch of the rescue door opening device 30 is connected to the self-rescue in place contactor 22. And the induction switch feeds back the car brake signal, and the self-rescue in place contactor 22 feeds back the door machine power-off signal.

[0044] In this way, when the car self-rescues and moves downward to the bottom of the shaft, abuts against and triggers the induction switch, the power system receives the car brake signal fed back by the induction switch and controls the car to stop self-rescue and move downward. At the same time, the self-rescue in place contactor 22 works with the triggering of the induction switch, and controls the door machine power supply to be disconnected, thereby opening the car door from the inside. The rescue door opening device 30 further opens the shaft door, so that the passengers can leave the car in time, overcoming the shear risk problem of the existing rescue system.

[0045] In addition, the rescue system also includes a voice announcer and a car height display 40, wherein the brake release delay relay 23, the self-rescue contactor 21, and the self-rescue in-place contactor 22 are respectively connected to the voice announcer. The car height display 40 is used to display the real-time height of the elevator car during the downward movement of the car self-rescue. The car height display 40 transmits signals with the distance sensor arranged at the bottom of the car, and displays the distance between the car and the bottom of the shaft detected by the distance sensor.

[0046] In this way, the voice prompt before the elevator self-rescue moves downward, the voice prompt during the elevator self-rescue moves downward, and finally the voice prompt after the elevator self-rescue moves downward to the position, provide voice guidance for the passengers, and display the real-time height of the car to the passengers during the elevator self-rescue moves downward, so as to fully soothe the psychological state of the passengers.

[0047] As mentioned above, the rescue door opening device 30 is used to open the hoistway door. Figure 3 As shown, the rescue door opening device 30 includes: a base plate 31, a transmission mechanism 32, a lock assembly 33, a rotating pressure plate 34 and an induction switch 35.

[0048] The rotating pressure plate 34 is pivotally connected to the bottom plate 31, and initially has an acute angle with the bottom plate 31. At the same time, a damping component can be arranged between the rotating pressure plate 34 and the bottom plate 31, and the damping component enables the rotating pressure plate 34 to maintain the initial angle relative to the bottom plate 31, and can enable the rotating pressure plate 34 to return to the initial position when the external force is released. For example, the damping component can be a spring, or a shaft damper, etc.

[0049] The induction switch 35 is located below the rotating pressure plate 34 in the initial state, and the rotating pressure plate 34 can press and trigger the induction switch 35 by pivoting itself. In this way, when the car moves downward to the bottom of the shaft, it can interact with the rotating pressure plate 34 and drive it to pivot and press and trigger the induction switch 35 below it.

[0050] The lock assembly 33 is installed on the hoistway door, and it can control the elevator hoistway door to be locked and unlocked. In one embodiment, the lock assembly 33 can adopt an existing triangular lock assembly 33, which is pivotally arranged on the elevator hoistway door. At this time, the triangular lock assembly 33 realizes the locking or unlocking of the elevator hoistway door by its own pivoting.

[0051] The rotating pressing plate 34 is connected to the lock assembly 33 through the transmission mechanism 32, and drives the lock assembly 33 to open the door by its own pivoting. In this way, when the rotating pressing plate 34 pivots, the lock assembly 33 can be driven to pivot through the transmission structure, thereby realizing the unlocking of the elevator shaft door.

[0052] The transmission mechanism 32 is a cable, one end of which is connected to the end of the rotating pressure plate 34, and the other end is connected to the lock assembly 33 through a cable end 320. Therefore, when the rotating pressure plate 34 pivots and presses the triggering induction switch 35, it can simultaneously pull the cable, thereby driving the lock assembly 33 to unlock.

[0053] Furthermore, in order to facilitate the installation and fixation of the above-mentioned cable, the rescue door opening device 30 further includes: a lower bracket 36, an upper bracket 37 and a sleeve 38. At this time, the lower bracket 36 is fixed on the bottom plate 31, the upper bracket 37 is arranged close to the lock assembly 33, the sleeve 38 is fixed on the lower bracket 36 and the upper bracket 37 respectively, and the cable passes through the sleeves 38 on the upper and lower brackets 36 in turn to connect with the lock assembly 33.

[0054] In summary, the present invention is aimed at the actual situation of villa elevators, and can provide rescue when a villa elevator fails, fully ensuring the personal safety of passengers. When a failure occurs, it can control the car to run downward for self-rescue, and when it runs to the bottom of the shaft, it triggers the rescue door opening device set at the bottom of the shaft, and then opens the car door and the shaft door, so that passengers can leave the car in time, and overcome the problem of shear risk in the existing rescue system.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
