Embodiment 1

[0032] Such as Figure 1-2 As shown, an automatic door opening and closing device includes a swing rod mechanism and a sensing device for sensing the approach of a human body. The swing rod mechanism includes a driving motor 2 and a swing rod 6. The driving motor 2 is fixedly arranged on the door frame 1 and is electrically connected to the access control system, the swing rod 6 is connected with the driving motor 2 through a gear pair transmission. The induction device is fixedly arranged on the door frame and electrically connected with the driving motor.

[0033] The sensing device includes an external trigger and an internal trigger (not shown in the figure) corresponding to the door opening direction and the closing direction of the door frame 1, and the external trigger and the internal trigger are fixedly arranged on the door frame 1 and both Electrically connected with the drive motor 2, when the trigger outside the door or the trigger inside the door senses that the ...

Embodiment 2

[0038] All the other are identical with embodiment 1, and difference is, as Figure 3-4 As shown, the transmission mechanism includes a sliding block 7 hinged with the swing rod 6 and a sliding slot 8 fixedly arranged on the door leaf 3 corresponding to the sliding block 7 , and the sliding block 7 and the sliding slot 8 are slidably connected.

[0039] When someone enters or exits the door, the trigger outside the door or the trigger inside the door outputs a signal to the drive motor, the drive motor starts to move forward, drives the swing rod to swing, and the slider starts to slide along the chute during the swing of the swing rod to realize the door leaf. purpose of opening. The driving motor is electrically connected with a timer circuit. When the swing rod rotates to the limit position, the timer circuit starts counting. When the timing is over, the driving motor starts to reverse, driving the swing rod to return, and at the same time, the arm and the connecting block ...

Embodiment 3

[0042] The rest is the same as that of Embodiment 2, except that the periphery of the door leaf is also provided with an inner detection area and an outer detection area surrounding the door leaf, and the inner detection area and the outer detection area are arranged concentrically. The trigger outside the door includes: a first trigger sensor, which is set in the outer detection area outside the door leaf; a second trigger sensor, which is set in the inner detection area, is set in pairs with the first trigger sensor, and is relative to the first trigger sensor The trigger is located near the center of the outer side of the door leaf; the trigger inside the door includes: the third trigger sensor, which is set in the outer detection area inside the door leaf; the fourth trigger sensor, which is set in the inner detection area, is paired with the third trigger sensor Set, and relative to the third trigger sensor is located near the center side of the inner side of the door leaf...

Abstract

An automatic door opening and closing device comprises an oscillating bar mechanism, an induction device and a transmission mechanism, wherein the induction device is used for inducing people when people approach a door; the oscillating bar mechanism comprises a driving motor and an oscillating bar; the driving motor is fixedly arranged on a door frame and is electrically connected with an access control system; the oscillating bar is in transmission connection with the driving motor; the induction device is fixedly arranged on the door frame and is electrically connected with the driving motor; and the transmission mechanism is respectively in transmission connection with the oscillating bar and a door sash. By using the automatic door opening and closing device, the door sash is automatically opened or closed relative to the door frame after the access control system is started; when people approach the door sash, the door sash can be opened automatically, and people can conveniently enter an indoor environment or exit from the indoor environment; after people leave away from the indoor environment, the door sash can be automatically closed; the automatic door opening and closing device brings great convenience to access of people.

Description

technical field [0001] The invention relates to an automatic door opening and closing device. Background technique [0002] As living standards improve, people demand an increased level of automation in their lives. Existing access control systems usually only have a door closer, which requires human hands to open the door, and then close the door through the door closer. Life brings great inconvenience. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide an automatic door opening and closing device, which can realize the automatic opening and closing of the door leaf when the access control system is unlocked. [0004] In order to achieve the above object, the technical solution of the present invention is as follows: an automatic door opening and closing device, which is used to automatically open and close the door leaf when the access control system is unlocked. Proximity sensing device...
