Abstract
Description
Technical Field
[0001] This utility model relates to the field of sightseeing elevator technology, and in particular to a sightseeing elevator with anti-pinch function. Background Technology
[0002] A sightseeing elevator is a type of elevator with special functions and designs. The elevator car is typically made of transparent glass or similar materials, allowing passengers to enjoy panoramic views of the surrounding scenery during their ride. The elevator shaft is also specially designed to match the overall style of the building and its environment, such as combining steel structures with glass curtain walls to complement the building's exterior and become a highlight of the architecture.
[0003] Modern elevators use light curtains to protect the doors when they close. These light curtains are infrared sensors installed in the elevator car. When an object blocks the light in the light curtain, it is immediately detected and a signal is transmitted to the elevator control system. If the elevator doors encounter strong resistance during closing, causing an object to enter the light curtain area, the light curtain protection will be triggered, and the elevator doors will immediately stop closing and reopen to prevent people or objects from being trapped.
[0004] In the implementation of existing technical solutions, although the anti-pinch function is achieved through light curtain protection, there may be installation errors because the light curtain is installed between the elevator car door and the landing door and is usually fixed by screws or other fixing devices. When the light curtain senses a person passing through, it immediately sends a signal, causing the elevator car door to close immediately. If the passenger does not have time to enter, he / she may be pinched. Summary of the Invention
[0005] The purpose of this utility model is to provide a sightseeing elevator with anti-pinch function, which can improve the sensing range and avoid the elevator closing due to incomplete sensing, thus achieving the anti-pinch effect. At the same time, the first and second through rods abut against each other and pass through the corresponding first and second car doors, avoiding the situation where the elevator cannot close due to mutual limitation when closing, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a sightseeing elevator with anti-pinch function, including a first car door, a second car door being movably connected to one side of the first car door, and an anti-pinch mechanism being provided between the first car door and the second car door;
[0007] The anti-pinch mechanism includes a first through rod that extends through the outer wall of the first car door and has a sensing device body embedded at its bottom end. A second through rod extends through the outer wall of the second car door and has a sliding plate fixedly installed at one end of the second through rod that enters the second car door. A fixing rod is fixedly installed on one side of the sliding plate and a sleeve is sleeved on the outside of the fixing rod.
[0008] Preferably, a limit ring is fixedly installed on the outside of one end of the fixing rod that passes through the sleeve, and a spring is embedded inside the sleeve.
[0009] Preferably, a slider is fixedly installed at the bottom of the sliding plate, and a groove is provided inside the second car door at the position corresponding to the slider.
[0010] Preferably, the limiting ring and the sleeve form a sliding structure, and the sleeve forms an elastic structure with the fixing rod via a spring.
[0011] Preferably, the first through rod is provided with a resistance mechanism, the resistance mechanism including a movable rod, the movable rod being slidably connected inside the second through rod, and a first permanent magnet block being fixedly installed at one end of the movable rod that passes through the first through rod.
[0012] Preferably, a sliding groove is provided inside the second through rod corresponding to the position of the movable rod, and an electromagnet is embedded in one side of the sliding groove. A second permanent magnet block is fixedly installed at one end of the second through rod located in the sliding groove.
[0013] Preferably, the movable rod and the sliding groove form a sliding structure, and the sliding groove and the second permanent magnet block form a sliding structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The main body of the sensing device embedded in the first and second through rods of this utility model can improve the sensing range and avoid incomplete sensing that could lead to elevator closure, thus achieving an anti-pinch effect. At the same time, the first and second through rods abut against each other and pass through the corresponding first and second car doors, preventing mutual limitation that could prevent the elevator from closing when it closes.
[0016] 2. This utility model uses the magnetism of an electromagnet to drive the first and second permanent magnet blocks with the same magnetic poles. This allows the elevator's self-protection mechanism to be triggered after the sensing device detects a person or object, thus preventing the elevator from closing and achieving an anti-pinch effect, further improving the safety of elevator use.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 4A sightseeing elevator with anti-pinch function includes a first car door 1, a second car door 2 movably connected to one side of the first car door 1, and an anti-pinch mechanism 3 between the first car door 1 and the second car door 2. The anti-pinch mechanism 3 includes a first through rod 301, which extends out of the outer wall of the first car door 1, and a sensing device body 303 is embedded at the bottom end of the first through rod 301. A second through rod 302 extends out of the outer wall of the second car door 2, and a sliding plate 304 is fixedly installed at one end of the second through rod 302 that enters the second car door 2. A fixing rod 305 is fixedly installed on one side of the sliding plate 304. A sleeve 306 is sleeved on the outside of the fixing rod 305. A limit ring 307 is fixedly installed on the outside of the end of the fixing rod 305 that passes through the sleeve 306. A spring 308 is embedded inside the sleeve 306. A slider 309 is fixedly installed at the bottom of the sliding plate 304. A groove 310 is opened inside the second car door 2 corresponding to the position of the slider 309. The limit ring 307 and the sleeve 306 form a sliding structure. The sleeve 306 and the fixing rod 305 form an elastic structure through the spring 308.
[0028] By adopting the above technical solution, the first through rod 301 and the second through rod 302 abut against each other and pass through the corresponding first car door 1 and second car door 2. The sensing device body 303 embedded below detects the movement, preventing incomplete light curtain protection that could cause the first car door 1 and second car door 2 to close, thus achieving an anti-pinch effect. If the sensing device body 303 detects no one or object, the first car door 1 and second car door 2 close, and the first through rod 301 and the second through rod 302 abut against each other. After contact, the corresponding sliding plate 304 is contacted and slides stably along the slide groove 310 via the slider 309, thereby allowing the fixed rod 305 to pass through the sleeve 306 to reserve the closing space of the first car door 1 and the second car door 2. When the elevator opens, the spring 308 pushes elastically to reset the corresponding first through rod 301 and the second through rod 302, so that the sensing device body 303 can always sense people or objects. The limiting ring 307 prevents the spring 308 from pushing too much and causing the fixed rod 305 to disengage from the sleeve 306.
[0029] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, a resistance mechanism 4 is provided inside the first through rod 301. The resistance mechanism 4 includes a movable rod 401, which is slidably connected inside the second through rod 302. A first permanent magnet block 402 is fixedly installed at one end of the movable rod 401 that passes through the first through rod 301. A sliding groove 404 is provided inside the second through rod 302 at the position corresponding to the movable rod 401. An electromagnet 405 is embedded in one side of the sliding groove 404. A second permanent magnet block 403 is fixedly installed at one end of the second through rod 302 located in the sliding groove 404. A sliding structure is formed between the movable rod 401 and the sliding groove 404, and a sliding structure is formed between the sliding groove 404 and the second permanent magnet block 403.
[0030] By adopting the above technical solution, when the sensing device body 303 senses the presence of a person or object inside, a signal is sent to activate the electromagnets 405 inside the first through rod 301 and the second through rod 302. This causes the first permanent magnet block 402 and the second permanent magnet block 403 with the same magnetic pole to slide along the sliding groove 404, so that the movable rod 401 is positioned at the first through rod 301 and the second through rod 302 and forms a certain resistance force. This triggers the protection mechanism when the elevator closes, preventing the elevator from closing and achieving an anti-pinch effect. When the sensing device body 303 senses no person or object, the electromagnet 405 is closed, and the elevator can open and close normally.
[0031] Working Principle: The first through-rod 301 extending from the first car door 1 and the second through-rod 302 extending from inside the second car door 2 are both equipped with infrared sensor bodies 303. These are used for secondary sensing, in addition to light curtain protection. The system only sends a signal to the elevator control system to close the doors once no person or object is obstructing the view. When the first car door 1 and the second car door 2 are closed normally, the first through-rod 301 and the second through-rod 302 abut against each other and pass through the corresponding first car door 1 and second car door 2. They then abut against the fixing rod 305 via the sliding plate 304 and pass through the corresponding sleeve 306 fixed inside the first car door 1 and second car door 2, preventing mutual contact from affecting elevator closure. The spring 308 elastically pushes the sliding plate 304 back to its original position after the elevator opens and closes, thus resetting the first through-rod 301 and the second through-rod 302. The sliding plate 304 improves the stability of the sliding process by using the slider 309 along the slide groove 310. The limiting ring 307 prevents the fixed rod 305 from being excessively pushed by the elasticity and falling off the sleeve 306. When the sensing device body 303 senses the presence of a person or object inside, the electromagnets 405 inside the first through rod 301 and the second through rod 302 are activated, pushing the first permanent magnet block 402 and the second permanent magnet block 403 of the same magnetic pole material to slide stably in the sliding groove 404, preventing the movable rod 401 from excessively penetrating the first through rod 301 and the second through rod 302, thus forming a resisting force. If the elevator is in an automatic or forced closing state, the elevator's own protection mechanism will be triggered after sensing this force, stopping the closing and opening to achieve an anti-pinch effect. When the sensing device body 303 senses no person or object, the closing electromagnet 405 allows the elevator to close and run normally.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such 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.
