Description

Technical Field

[0001] This utility model belongs to the field of elevator anti-pinch technology, and in particular relates to a medical elevator door buffer anti-pinch device. Background Technology

[0002] Medical elevators are elevators specifically designed for use in hospitals and other medical facilities, primarily for transporting hospital beds, patients, and medical equipment. Compared to ordinary elevators, medical elevators differ significantly in design and function to meet the needs of the medical environment, and their design and manufacturing place higher demands on safety.

[0003] Currently, elevator doors are equipped with anti-pinch devices, which typically use photoelectric anti-pinch devices on both sides of the door panel. These devices detect obstacles by emitting and receiving light beams. When the light beam is blocked, the elevator door stops closing and reopens. However, photoelectric anti-pinch devices are prone to beam obstruction during use, especially by small objects such as ropes or the corners of clothing. In addition, photoelectric anti-pinch devices are prone to malfunction after prolonged use, leading to door panel damage. Utility Model Content

[0004] This utility model provides a medical elevator door buffer anti-pinch device, which aims to solve the problems of loopholes in the current elevator anti-pinch system and the inability to achieve anti-pinch after a malfunction.

[0005] This utility model is implemented as follows: a medical elevator door buffer anti-pinch device includes a frame and a door panel; a drive plate is installed in the frame, and the drive plate and the door panel each have two sets of drive plates; each side surface of the door panel away from each other has a sliding groove, and a slider is slidably installed in the sliding groove; a support plate is installed on the side of the drive plate, and the support plate is connected to the slider; a connecting plate is installed on the central side of the drive plate, and a sleeve plate is slidably sleeved on the outer side of the connecting plate; a spring is installed on the inner side of the sleeve plate, and the movable end of the spring is connected to the inner end of the connecting plate; a sliding groove is opened on the central side of the door panel, and a pressure sensor is installed in the sliding groove; the pressure sensor is electrically connected to the drive mechanism of the drive plate; the end of the sleeve plate away from the connecting plate is connected to the sensing port of the pressure sensor.

[0006] Preferably, an infrared transmitter is installed at the top center of the frame, with the transmitter port facing vertically downwards. A semi-circular slot is formed on the surface of the two sets of door panels that are close to each other from top to bottom, and a receiver is installed at the bottom of the slot. The receiver is electrically connected to the elevator's operation switch.

[0007] Preferably, the upper surface of the receiver is provided with a plurality of receiving points adapted to the infrared transmitter.

[0008] Preferably, the top of the frame is equipped with two sets of electromagnetic latches, and the top of the two sets of door panels is provided with slots that are compatible with the electromagnetic latches.

[0009] Preferably, the electromagnetic latch is equipped with a remote control module, and the electromagnetic latch is dually controlled by the elevator control system and the remote control module. Embedded safety grooves are opened on the inner and outer surfaces of both sets of door panels.

[0010] Preferably, a loudspeaker is mounted on the top of the frame.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] By setting up a pressure sensor to monitor the pressure received by the door panel, when the door panel clamps an object, the pressure received by the pressure sensor increases, and the drive mechanism of the drive board is stopped and the door panel is opened through an electrical signal, thereby achieving anti-pinch. By sliding the drive board to the door panel, a certain buffer distance can be provided to the door panel. In the event of a pressure sensor failure, the door panel will not be forced to close directly under force, providing a buffer distance for the elevator door and giving users time to react, thereby effectively improving the anti-pinch function and safety of the elevator.

[0013] The infrared transmitter extends from the top of the frame to the groove in the door panel, emitting infrared rays downwards. This covers the entire vertical range without blind spots, preventing accidents caused by small ropes or other objects getting caught in the infrared signal. By setting multiple receiving points on the receiver, the elevator can only operate when all receiving points fully recognize the infrared signal, further improving the signal triggering accuracy. An electromagnetic latch is also included. Since the door panel and drive plate can move relative to each other, when the door panel is closed and the elevator is running, the electromagnetic latch is activated and inserted into the slot in the door panel, preventing the door panel from being accidentally pried open, thus improving the elevator's safety.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a medical elevator door buffer anti-pinch device, such as... Figure 1-5As shown, the elevator includes a frame 1 and a door panel 3. A drive plate 2 is installed in the frame 1. Both the drive plate 2 and the door panel 3 have two sets of drive plates. Each side of the door panel 3 away from each other has a groove, and a slider 4 is slidably installed in the groove. A support plate 5 is installed on the side of the drive plate 2, and the support plate 5 is connected to the slider 4. A connecting plate 6 is installed on the center side of the drive plate 2. A sleeve plate 7 is slidably fitted onto the outer side of the connecting plate 6. A spring 9 is installed on the inner side of the sleeve plate 7, and the movable end of the spring 9 is connected to the inner end of the connecting plate 6. A groove is also provided on the center side of the door panel 3, and a pressure sensor 8 is installed in the groove. The pressure sensor 8 is electrically connected to the drive mechanism of the drive plate 2. The end of the sleeve plate 7 away from the connecting plate 6 is connected to the sensing port of the pressure sensor 8. The elevator consists of a frame 1, a drive plate 2, and a door panel 3. The drive mechanism of the drive plate 2 is a motor screw, hydraulic system, etc. The drive plate 2 consists of a support plate 5 and slider 4. The door panel 3 is supported by the connecting plate 6, the sleeve plate 7, and the pressure sensor 8. The door panel 3 is pushed and pulled by the connecting plate 6, the sleeve plate 7, and the pressure sensor 8. When the drive plate 2 pushes the door panel 3 to close and clamps an object, the pressure sensor 8 receives increased pressure and controls the drive mechanism of the drive plate 2 to stop running and open the door panel 3 through an electrical signal. This achieves anti-pinch function. Because the door panel 3 and the slider 4 are slidably connected, if the door panel 3 clamps an object and the pressure sensor 8 malfunctions, causing the drive plate 2 to continue driving the door panel 3 to close, the connecting plate 6 will slide inward into the sleeve plate 7 and compress the spring 9. At this time, the door panel 3 only receives the pressure of the spring 9. The spring 9 has good elastic deformation, so it provides a certain buffer distance for the door panel 3 and does not force the door panel 3 to close directly. This provides a buffer gap for the elevator door and gives the user time to react, thereby effectively improving the anti-pinch function and safety of the elevator.

[0023] An infrared transmitter 10 is installed at the top center of frame 1, with the transmitter port of infrared transmitter 10 facing vertically downwards. A semi-circular groove is opened from top to bottom on the surface of the two door panels 3 that are close to each other, and a receiver 11 is installed at the bottom of the groove. The receiver 11 is electrically connected to the elevator's operation switch. With the infrared transmitter 10 installed, infrared rays are emitted downwards from the top of frame 1 and received by the receiver 11 at the bottom of the groove of door panel 3. When door panel 3 clamps a thin object and closes, it will block the receiver 11. The receiver 11 will not receive the infrared signal and will not make the elevator move up or down. The infrared transmitter 10 extends from the top of frame 1 to the groove of door panel 3 and emits infrared rays downwards, so it can cover the entire vertical range without dead angles, avoiding accidents caused by clamping thin ropes or other objects.

[0024] The upper surface of the receiver 11 is provided with several receiving points adapted to the infrared transmitter 10. By setting multiple receiving points on the receiver 11, the elevator can only run after the receiving points of the receiver 11 have fully recognized the infrared signal, thereby further improving the triggering accuracy of the signal.

[0025] Two sets of electromagnetic latches 12 are installed on the top of the frame 1. The top of the two sets of door panels 3 are provided with slots that are compatible with the electromagnetic latches 12. With the electromagnetic latches 12 installed, the door panels 3 and the drive plate 2 can move relative to each other. When the door panels 3 are closed and the elevator is running, the electromagnetic latches 12 are activated and inserted into the slots of the door panels 3, which prevents the door panels 3 from being accidentally pried open, thereby improving the safety of the elevator.

[0026] The electromagnetic latch 12 is equipped with a remote control module 13. The electromagnetic latch 12 is controlled by both the elevator control system and the remote control module 13. The inner and outer surfaces of both sets of door panels 3 are provided with embedded safety grooves 15. With the remote control module 13, when the elevator malfunctions, the electromagnetic latch 12 can be opened through the remote control module 13. The trapped personnel can pull the safety grooves 15 of the door panels 3 to open the door panels 3 by a small gap, so that the elevator can be ventilated and can call for help.

[0027] A loudspeaker 14 is installed at the top of the frame 1. By setting the loudspeaker 14, the user can be reminded that the elevator door is open or closed, thereby achieving a warning effect.
