Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety, in particular to an anti-pinch device for elevator door gaps. Background Technique

[0002] In modern buildings, elevators, as important vertical transportation tools, have been widely used in various occasions. However, during the use of elevators, accidents of passengers being pinched by elevator door gaps occur from time to time. Especially during peak hours, when passengers are crowded when entering and leaving the elevator, children, the elderly or passengers carrying large items are often at risk of being pinched by elevator doors. Therefore, how to effectively prevent accidents of being pinched by elevator door gaps has become an important research direction in the field of elevator safety.

[0003] Most of the existing elevator anti-pinch devices rely on simple mechanical structures or single induction mechanisms. Although they can reduce the occurrence of pinching accidents to a certain extent, there are still the following deficiencies:

[0004] Incomplete induction coverage: Some existing devices only set induction mechanisms in specific areas of the elevator door, making it difficult to achieve comprehensive monitoring of the entire door gap area. Especially the protection dead angle at the bottom end may lead to false detection or missed detection.

[0005] Lack of visual warning: Most anti-pinch devices lack obvious visual warning signs, resulting in passengers not being able to detect the potential danger of the door gap in time when using the elevator, thus increasing the risk of pinching accidents.

[0006] Therefore, we propose an anti-pinch device for elevator door gaps. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1-2 , in the embodiment of the present utility model, an anti-pinch device for an elevator door gap includes a movable door 1, an infrared sensing mechanism, a bottom anti-pinch mechanism, and a warning mechanism.

[0024] There are two movable doors 1 in total. An infrared sensing mechanism is provided on the outer end surfaces of the two movable doors 1. The infrared sensing mechanism includes an infrared emitter 3 and an infrared receiver 5. The infrared emitter 3 is fixedly connected to the outer end surface of one movable door 1, and the infrared receiver 5 is fixedly connected to the outer end surface of the other movable door 1.

[0025] It should be noted that the infrared sensing mechanism is composed of an infrared emitter 3 and an infrared receiver 5. By respectively arranging the emitter and the receiver on the outer end surfaces of the two movable doors 1, when there is an object (such as a passenger's body part or an item carried) in the elevator door gap, the infrared sensing mechanism can quickly detect and send a signal, timely prevent the elevator door from closing further, and avoid the occurrence of pinching accidents. Infrared sensing belongs to non-contact sensing technology, which can perform detection without direct contact with the object. This not only improves the sensitivity and accuracy of detection, but also avoids the wear and failure risks that may be brought by traditional mechanical trigger devices, and improves the reliability and service life of the device.

[0026] A bottom anti-pinch mechanism is provided at the bottom of the movable door 1. The bottom anti-pinch mechanism includes a slide rail 7, a sliding plate 13, and a filling plate 10. The slide rail 7 is fixedly connected to the bottom of the movable door 1. The sliding plate 13 is slidably connected in the slide rail 7. The lower surface of the sliding plate 13 is fixedly connected to the filling plate 10. A chute 8 is formed on the upper surface of the sliding plate 13. A fixing plate 9 is fixedly connected between the inner side walls on both sides of the chute 8. And a connecting plate 11 is fixedly connected to the upper inner wall of the slide rail 7. A spring 12 is connected between the connecting plate 11 and the fixing plate 9.

[0027] It should be noted that when the elevator door is closed, the slide plate can move smoothly in the slide rail, and under the action of the rebound force of the spring 12, the filling plate 10 under the slide plate 13 is pushed out of the slide rail 7, so that it automatically fills the door gap space when the elevator door is closed, forming a substantial barrier, thereby preventing passengers' shoes, clothes or other items from being caught in the door gap, reducing the incidence of pinching accidents, and the design of the spring 12 pushing the filling plate 10 reduces the reliance on complex mechanical structures and reduces the probability of mechanical failure of the device.

[0028] The inner end surface of the movable door 1 is provided with a warning mechanism, which includes a warning strip 2 and a sign 6. The warning strip 2 is fixedly adhered to the outer side of the inner end surface of the movable door 1, and the sign 6 is adhered to the inner end surface of the movable door 1.

[0029] It should be noted that the warning strip 2 is designed with eye-catching colors and patterns, which can quickly attract the attention of passengers when they approach the elevator door, reminding passengers to stay away from the door gap area to prevent pinching accidents caused by approaching the elevator door. The signboard 6 clearly indicates safety tips, which further enhances the passengers' safety awareness. When passengers see these warning signs, they will be more cautious in entering and exiting the elevator, reducing the risk of accidental injury caused by negligence.

[0030] The outer end surface of the movable door 1 is fixedly bonded with a cushion 4. When the elevator door is closed, the cushion 4 can provide soft buffering protection to prevent the elevator door from directly contacting the passenger's body or the items carried by the passenger, thereby reducing the risk of pinching caused by impact.

[0031] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
