Description

Technical Field

[0001] This application relates to the field of automatic door technology, and more particularly to an automatic door with an anti-pinch mechanism. Background Technology

[0002] An automatic door is a control unit that can recognize a person's approach to the door as an opening signal, open the door through a drive system, and automatically close the door after the person leaves.

[0003] Existing automatic doors are equipped with anti-pinch mechanisms to prevent people or objects from being pinched. However, existing automatic doors use only one type of anti-pinch method, and most of them use infrared sensors. This method cannot cover the entire door, so there are often cases where the sensors fail to detect certain objects, which affects the safety of the automatic door. Therefore, in order to correct the above-mentioned defects, we propose an automatic door with an anti-pinch mechanism. Utility Model Content

[0004] In view of the above problems, this application provides an automatic door with an anti-pinch mechanism to solve the problem that the anti-pinch method cannot cover the entire door, which easily leads to the phenomenon that the sensor cannot detect the problem and affects the safety of the automatic door.

[0005] This application provides an automatic door with an anti-pinch mechanism, including a positioning compartment: a pair of limiting compartments are fixedly connected to the bottom of the positioning compartment, a door panel is provided inside the limiting compartment, a movable groove is opened on the side wall of the door panel, a movable plate is provided in the movable groove, a rubber strip is fixedly connected to the side wall of the movable plate, and a plurality of first rectangular grooves are opened on the movable plate and the rubber strip, a photoelectric sensor is fixedly connected to the inner wall of the first rectangular groove, a pair of second rectangular grooves are opened on the inner wall of the movable groove, a limiting block is provided in the second rectangular groove, the other side of the limiting block is fixedly connected to the side wall of the movable plate, a plurality of springs are fixedly connected between the movable plate and the inner wall of the movable groove, a pressure sensor is fixedly connected to the inner wall of the second rectangular groove, and a driving mechanism is provided inside the positioning compartment.

[0006] In some embodiments, the drive mechanism includes a pair of electric telescopic rods, which are fixedly connected to the inner wall of the positioning chamber. The output shaft of each electric telescopic rod is fixedly connected to an adjusting block. The bottom of the positioning chamber has a pair of movable openings, and the bottom of the adjusting block passes through the movable openings and is fixedly connected to the top of the door panel.

[0007] In some embodiments, a controller is fixedly connected to the side wall of the limiting chamber, and the controller, the electric telescopic rod, the pressure sensor and the photoelectric sensor are electrically connected.

[0008] In some embodiments, a plurality of the photoelectric sensors are equidistantly distributed on the sidewall of the movable plate, and each pair of the limiting blocks are symmetrically arranged about the central axis of the door plate.

[0009] In some embodiments, the height of the pair of movable plates is equal to the inner cavity height of the movable slot, and the thickness of the door plate is equal to the inner cavity width of the limiting chamber.

[0010] In some embodiments, connecting blocks are fixedly connected to the two side walls of the positioning chamber, and the connecting blocks have circular holes.

[0011] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0012] 1. By incorporating photoelectric sensors, door panels, movable panels, and pressure sensors, during the closing process of a pair of door panels, the photoelectric sensor detects a human body or object and sends a signal to the controller. The controller then controls the start and stop of the electric telescopic rod, thereby stopping the door panel movement. If the photoelectric sensor fails to detect a human body or object, causing the movable panel and rubber strip to squeeze the human body or object, the human body or object will push the movable panel in the opposite direction, which in turn pushes the limit block. This limit block then squeezes the pressure sensor, which sends an electrical signal to the controller. The controller then controls the start and stop of the electric telescopic rod, thus preventing the human body or object from being pinched. Therefore, by employing multiple anti-pinch methods, the anti-pinch effect of the automatic door is improved. Attached Figure Description

[0027] In the technical solution of this application embodiment, the door panel 3 can be moved by the drive mechanism, thereby realizing the opening and closing of the automatic door. The drive mechanism includes a pair of electric telescopic rods 13, which are fixedly connected to the inner wall of the positioning chamber 1. The output shaft of the electric telescopic rod 13 is fixedly connected to an adjusting block 14. A pair of movable openings 15 are provided at the bottom of the positioning chamber 1. The bottom of the adjusting block 14 passes through the movable openings 15 and is fixedly connected to the top of the door panel 3. A controller 16 is fixedly connected to the side wall of the limiting chamber 2. The controller 16, the electric telescopic rods 13, the pressure sensor 12 and the photoelectric sensor 8 are electrically connected.

[0028] In the technical solution of this application embodiment, multiple photoelectric sensors 8 are equidistantly distributed to improve the detection range of the photoelectric sensors 8. Several photoelectric sensors 8 are equidistantly distributed on the side wall of the movable plate 5. Each pair of limiting blocks 10 is symmetrically arranged about the central axis of the door panel 3. The height of a pair of movable plates 5 is equal to the inner cavity height of the movable groove 4. The thickness of the door panel 3 is equal to the inner cavity width of the limiting chamber 2. Connecting blocks 17 are fixedly connected to the two side walls of the positioning chamber 1. The connecting blocks 17 are provided with round holes.

[0029] Working principle: When in use, the electric telescopic rod 13 is started, which drives the adjusting block 14 to move. The adjusting block 14 drives the door panel 3 to move, thereby closing the pair of door panels 3. During the closing process of the pair of door panels 3, the photoelectric sensor 8 detects a human body or object and sends a signal to the controller 16. The controller 16 controls the start and stop of the electric telescopic rod 13, thereby stopping the movement of the door panel 3. If the photoelectric sensor 8 does not detect a human body or object, the movable plate 5 and the rubber strip 6 will squeeze the human body or object. At this time, the human body or object will push the movable plate 5 to move in the opposite direction. The movable plate 5 will push the limit block 10 to move, thereby squeezing the pressure sensor 12 through the limit block 10. The pressure sensor 12 sends an electrical signal to the controller 16, and the controller 16 controls the start and stop of the electric telescopic rod 13, thereby preventing the human body or object from being pinched.
