Description

Technical Field

[0001] The utility model relates to the technical field of automatic door switches, in particular to an automatic door with adjustable door opening and closing amplitude and speed. Background Art

[0002] In theory, automatic doors are an extension of the concept of doors, evolving and improving their functionality based on human needs. The automatic door industry is maturing. An automatic door is a control unit that recognizes a person approaching the door (or granting some kind of entry authorization) as a signal to open. It then drives the door open, automatically closing it after the person leaves, and controlling the entire opening and closing process.

[0003] At present, traditional automatic doors are generally composed of a servo motor, an infrared sensor, a controller, a bidirectional screw and two doors. When working, when a person walks in front of the door, the infrared sensor will detect the approach of the person and transmit the signal to the controller. The controller starts the servo motor to work, and the servo motor will drive the bidirectional screw to rotate. When the bidirectional screw works, it can drive the two doors to move in opposite directions, thereby opening the door. When a person passes through the door, the infrared sensor will not be able to detect the person. At this time, the controller will control the servo motor to rotate in the opposite direction, which can drive the two doors to move in opposite directions, thereby closing the door.

[0004] Since the above-mentioned automatic door, when working, will rely solely on the infrared sensor to open and close the two doors, if the infrared sensor is damaged or a person stands in the blind spot of the infrared sensor, the automatic door will start to close. If the person or object does not pass through the automatic door in time, it will easily cause people to be pinched or objects to be damaged. Utility Model Content

[0025] Example 1

[0026] In order to solve the technical problems in the background technology, the following automatic door with adjustable opening and closing amplitude and speed is provided:

[0027] Combine Figure 1-Figure 5As shown, the automatic door with adjustable door opening and closing amplitude and speed provided by the present invention comprises a door frame 1; a split moving assembly 2 is installed on the upper part of one side of the door frame 1, a limit assembly 3 is installed on one side of the split moving assembly 2, a split door assembly 4 is installed in the middle part of one side of the door frame 1, the top surface of the split door assembly 4 is connected to the split moving assembly 2, and an infrared temperature sensor 5 is fixedly connected to the upper part of the other side of the door frame 1; the split door assembly 4 comprises a left-opening door 41, a right-opening door 42, an upper track 43 and a lower track 44, and the left-opening door 41 is installed on one side of the door frame 1 respectively. And the right-opening door 42, the two ends of the upper part of one side of the door frame 1 are fixedly connected with the upper track 43, and the lower part of one side of the door frame 1 is fixedly connected with the lower track 44. There are two groups of upper tracks 43 and lower tracks 44. The bottom surfaces of the left-opening door 41 and the right-opening door 42 are fixedly connected with guide blocks 45, and the guide blocks 45 are located in the lower track 44 and slide. One end of the left-opening door 41 is equipped with a first anti-pinch component 46, and one end of the right-opening door 42 is equipped with a second anti-pinch component 47. One side of the first anti-pinch component 46 is in contact with one side of the second anti-pinch component 47. The first anti-pinch component 46 includes a U-shaped block 461, fixedly connected to one end of the left-opening door 41. A C-shaped block 462 is fixedly connected to one side of the U-shaped block 461. A sliding post 463 is fixedly connected to the interior of the C-shaped block 462. A sliding block 464 is slidably connected to the outer surface of the sliding post 463. A return spring 465 is fixedly connected to the top surface of the sliding block 464, located between the inner surface of the C-shaped block 462. A connecting rod 466 is rotatably connected to one side of the sliding block 464 via a lug that fits a pin.

[0029] Example 2

[0030] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0031] The split moving assembly 2 includes a split track 21 and a servo motor 22. The split track 21 and the servo motor 22 are fixedly connected to the upper part of one side of the door frame 1. The bottom surface of the split track 21 is provided with a split groove 23. A bidirectional threaded rod 24 is rotatably connected in the split groove 23. The outer surfaces of the bidirectional threaded rod 24 are threadedly connected with clamping blocks 25 at both ends. The top surfaces of the left-opening door 41 and the right-opening door 42 are fixedly connected with the clamping blocks 25, and the output shaft end of the servo motor 22 is fixedly connected with the bidirectional threaded rod 24.

[0032] The servo motor 22 in the split moving assembly 2 drives the bidirectional threaded rod 24 to rotate. When the bidirectional threaded rod 24 works, it drives the two sets of clamps 25 to move inward or outward at the same time, thereby driving the left door 41 and the right door 42 to open and close.

[0033] Example 3

[0034] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0035] The limiting assembly 3 includes a limiting rail 31, and the two ends of one side of the split rail 21 are respectively fixedly connected to the limiting rail 31. A limiting groove 32 is provided on one side of the limiting rail 31. A limiting threaded rod 33 is rotatably connected in the limiting groove 32. The outer surface of the limiting threaded rod 33 is threadedly connected to the limiting block 34. A touch sensor 35 is fixedly connected to one side of the limiting block 34, and one side of the clamping block 25 is in contact with the touch sensor 35.

[0036] The limiting block 34 is driven to move by the limiting threaded rod 33 in the limiting assembly 3, thereby changing the position of the touch sensor 35, so that when the door is opened later, the distance between the left door 41 and the right door 42 when opening and closing can be controlled to adapt to the distance of opening of different doors.

[0037] The working principle and use process of this utility model:

[0038] In use:

[0039] The infrared temperature sensor 5 uses a temperature sensor detector JA-830, and the touch sensor 35 uses a photoelectric sensor switch ET318BI.3 / 2N / FT318I. At the same time, the servo motor 22, the infrared temperature sensor 5 and the touch sensor 35 are all connected to an external controller, and the rotation speed of the servo motor 22 during operation is also controlled by the external controller.

[0040] Before operation, first adjust the limit assembly 3 according to the size of the door opening. When adjusting, first rotate the limit threaded rod 33, which drives the limit block 34 to move. When the limit block 34 moves, it also drives the touch sensor 35 to move. When the touch sensor 35 moves to the specified position, the rotation of the limit threaded rod 33 can be stopped.

[0041] When in use, when a person approaches the door, the infrared temperature sensor 5 starts to detect and feeds back the detected result to the external controller. When the external controller determines that a person is approaching, it starts the servo motor 22. When the servo motor 22 is working, it will drive the bidirectional threaded rod 24 to rotate. When the bidirectional threaded rod 24 rotates, it starts to drive the clamping block 25 to move in the opposite direction, thereby driving the left door 41 and the right door 42 to move to both sides, opening the door to facilitate the entry of people. When the clamping block 25 moves, it will contact the touch sensor 35. After contact, the touch sensor 35 will send information to the external controller, and the external controller immediately stops the servo motor 22. At this time, the left door 41 and the right door 42 will also stop moving to both sides, thereby realizing the opening of the door. When the person passes, the servo motor 22 is reversed, so that the left door 41 and the right door 42 move in opposite directions, thereby realizing closing the door.
