Description
Technical Field
[0001] The utility model relates to the technical field of automatic doors, in particular to an automatic door intelligent time-delayed closing device. Background Art
[0002] Theoretically, automatic doors should be understood as an extension of the concept of doors, and the functions of doors are developed and improved according to human needs. The automatic door industry has been gradually maturing. Automatic doors refer to a control unit that can recognize the action of a person approaching the door (or a certain entry authorization) as a door opening signal, open the door through a drive system, and automatically close the door after the person leaves, and control the opening and closing process.
[0003] There are two methods for exiting and opening the door in the existing automatic door system, one is an exit switch button, the other is a human detector, or both are installed, but the two are installed in separate systems. This will result in that if a human detection device is installed, the detection device will open the door when it detects activity, which will cause frequent useless actions, waste power resources, and reduce the service life of the automatic door. If there is only a button to open the door, and there is no human activity detection device, once multiple people enter and exit at the same time, someone must continue to press the button, or press the exit switch but have a temporary conversation in front of the door, missing the automatic door opening time, and having to return to press the exit switch again, which is very cumbersome. Therefore, we propose an automatic door intelligent delay closing device. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. There are two methods for the existing automatic door system to open the door, one is an exit switch button, and the other is a human detector, or both are installed, but the two are installed in separate systems. This will result in that if a human detection device is installed, the detection device will open the door when it detects activity, which will cause frequent useless actions, waste power resources, and reduce the service life of the automatic door. If there is only a button to open the door, and there is no human activity detection device, once multiple people enter and exit at the same time, someone must continue to press the button, or press the exit switch but have a temporary conversation in front of the door, miss the automatic door opening time, and have to return to press the exit switch again, which is very cumbersome.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The intelligent holding delayed closing mechanism includes a control main board, a first relay is provided at the center and near the left side of the control main board, a second relay is provided on the right side of the first relay, a third relay is provided on the right side of the second relay, a first normally open contact is provided below the first relay, a second normally open contact is provided on the right side of the first normally open contact, a third normally open contact is provided on the right side of the second normally open contact, a first delay circuit is provided on the right side of the third normally open contact, and a second delay circuit is provided on the right side of the first delay circuit.
[0008] As a preferred solution of the utility model, the exit button is electrically connected to the first delay circuit and the first relay.
[0009] The technical effect of adopting the above further solution is: pressing the exit button triggers the first delay circuit and activates the first relay.
[0010] As a preferred solution of the utility model, the first normally open contact is electrically connected to the second delay circuit, the second relay, the second normally open contact, the human activity detector, the third relay, and the third normally open contact.
[0011] The technical effect of adopting the above further scheme is: the first normally open contact of the first relay is connected to the second delay circuit, after the second delay circuit is triggered, the second relay is activated, the second normally open contact of the second relay controls the human activity detector and the third relay, and the third normally open contact of the third relay is connected to the automatic door controller to open the automatic door body.
[0012] As a preferred solution of the utility model, the human activity detector, the second delay circuit, the second relay and the third relay form a working path.
[0013] The technical effect of adopting the above further scheme is: the output signal of the human activity detector can in turn activate the second delay circuit to achieve self-locking. Before the countdown of the second delay circuit ends, the second relay is always maintained, the human activity detector is always powered on and working, the third relay is always activated, and the automatic door remains open.
[0014] As a preferred solution of the utility model, the human activity detector is electrically connected to the second delay circuit, the third relay and the automatic door body.

At this time, the third relay continues to operate and the automatic door body continues to remain open.
[0016] As a preferred solution of the utility model, the human activity detector is electrically connected to the second delay circuit, the second relay and the third relay.
[0017] The technical effect of adopting the above further scheme is: when a person leaves, the human activity detector stops sending signals to the second delay circuit, the second delay circuit counts down normally, and the second relay is released after the timing ends. The human activity detector and the third relay lose power and stop working, the automatic door body opening signal is disconnected, and the automatic door body closes according to the program design.
[0018] As a preferred solution of the utility model, the exit button is electrically connected to the human activity detector.
[0019] The technical effect of adopting the above further solution is: when someone passes by the human activity controller without pressing the exit button, since the human activity controller is not powered and does not work, the door opening signal will not be triggered and the automatic door body will not open.
[0020] Compared with the prior art, the beneficial effects of the utility model are:
[0021] In the utility model, through the design of human activity detector, automatic door controller and intelligent delay closing mechanism, the automatic door body will not be automatically opened when someone passes by the door at ordinary times, and the door will not be automatically closed when the exit button is pressed once, and multiple people queue up to go out or temporarily talk in front of the door until all the people leave the detection range, and then the door will automatically close, effectively avoiding the problem that there are two methods for exit opening action of the existing automatic door system, one is the exit switch button, and the other is the human detector, or both are installed, but the two are independently installed systems, which will result in that if a human detection device is installed, the detection device will open the door when it detects activity, which will cause frequent useless actions, waste power resources, and reduce the service life of the automatic door. If there is only a button to open the door, and there is no human activity detection device, once multiple people enter and exit at the same time, someone must continue to press the button, or press the exit switch but have a temporary conversation in front of the door, miss the automatic door opening time, and have to return to press the exit switch again, which is a very cumbersome problem.

The term "and / or" used in this article includes any and all combinations of one or more related listed items.
[0029] Example 1
[0030] like Figure 1-2As shown, the utility model provides a technical solution: an automatic door intelligent delay closing device, comprising a structural body 1, a human activity detector 2 is arranged at the center of the interior of the structural body 1, an automatic door controller 3 is arranged on the right side and near the top of the human activity detector 2, an intelligent delay closing mechanism 4 is arranged below the automatic door controller 3, automatic door bodies 5 are arranged on both sides of the bottom of the structural body 1, and exit buttons 6 are arranged on the right sides of the two automatic door bodies 5, and the intelligent delay closing mechanism 4 comprises a control main board 401, a first relay 402 is arranged at the center and near the left side of the control main board 401, a second relay 403 is arranged on the right side of the first relay 402, a third relay 404 is arranged on the right side of the second relay 403, a first normally open contact 405 is arranged below the first relay 402, a second normally open contact 406 is arranged on the right side of the first normally open contact 405, a third normally open contact 407 is arranged on the right side of the second normally open contact 406, a first delay circuit 408 is arranged on the right side of the third normally open contact 407, and the first delay circuit A second delay circuit 409 is provided on the right side of 408. Through the design of the human activity detector 2, the automatic door controller 3 and the intelligent delay closing mechanism 4, when someone passes by the door at ordinary times, the automatic door body 5 will not be automatically opened. Moreover, if the exit button 6 is pressed once, and multiple people queue up to go out or have a temporary conversation in front of the door, the door will not be automatically closed until all the people leave the detection range, and the door will be automatically closed, which effectively avoids the existing automatic door system. There are two methods for door opening when going out, one is the exit switch button, and the other is the human detector, or both are installed, but the two are installed independently of each other. This will result in that if a human detection device is installed, the detection device will open the door when it detects activity, which will cause frequent useless actions, waste power resources, and reduce the service life of the automatic door. If there is only a button to open the door, and there is no human activity detection device, once multiple people enter and exit at the same time, someone must continue to press the button, or press the exit switch but have a temporary conversation in front of the door, miss the automatic door opening time, and have to return to press the exit switch again, which is a very cumbersome problem.
[0031] Example 2
[0032] like Figure 1-2As shown, the utility model provides a technical solution: the exit button 6 is electrically connected to the first delay circuit 408 and the first relay 402. When the exit button 6 is pressed, the first delay circuit is triggered, the first relay 402 is activated, the first normally open contact 405 is electrically connected to the second delay circuit 409, the second relay 403, the second normally open contact 406, the human activity detector 2, the third relay 404, and the third normally open contact 407. The first normally open contact 405 of the first relay 402 is connected to the second delay circuit 409. After the second delay circuit 409 is triggered, the second normally open contact 406 is activated. The second normally open contact 406 of the second relay 403 controls the human activity detector 2 and the third relay 404. The third normally open contact 407 of the third relay 404 is connected to the automatic door controller 3 to open the automatic door body 5. The human activity detector 2 and the second delay circuit 409, the second relay 403 and the third relay 404 form a working path. The output signal of the human activity detector 2 can in turn activate the second delay circuit 409 to achieve self-locking. Before the countdown of the second delay circuit 409 ends, the second relay 403 is kept on, and the human activity detector 2 is kept on. The detector 2 is always powered on and working, the third relay 404 is always activated, the automatic door remains open, the human activity detector 2 is electrically connected to the second delay circuit 409, the third relay 404 and the automatic door body 5. When the human activity detector 2 detects human activity, it will continue to send a signal to the second delay circuit 409 to restart the countdown. At this time, the third relay 404 continues to operate, and the automatic door body 5 continues to remain open. The human activity detector 2 is electrically connected to the second delay circuit 409, the second relay 403 and the third relay 404. When a person leaves, the second door body 5 is closed. After opening, the human activity detector 2 stops sending signals to the second delay circuit 409, and the second delay circuit 409 counts down normally. After the timing is over, the second relay 403 is released, and the human activity detector 2 and the third relay 404 lose power and stop working. The door opening signal of the automatic door body 5 is disconnected, and the automatic door body 5 is closed according to the program design. The exit button 6 is electrically connected to the human activity detector 2. When the exit button 6 is not pressed and someone passes by the human activity controller, since the human activity controller is not powered on and does not work, the door opening signal will not be triggered and the automatic door body 5 will not open.
[0033] The working process of the utility model is as follows: when using an automatic door intelligent delay closing device, first, press the exit button 6 to trigger the first delay circuit, activate the first relay 402, the first normally open contact 405 of the first relay 402 is connected to the second delay circuit 409, after the second delay circuit 409 is triggered, activate the second relay 403, the second normally open contact 406 of the second relay 403 controls the human activity detector 2 and the third relay 404, the third normally open contact 407 of the third relay 404 is connected to the automatic door controller 3, so that the automatic door body 5 is opened, the output signal of the human activity detector 2 can in turn activate the second delay circuit 409 to achieve self-locking, before the countdown of the second delay circuit 409 ends, the second relay 403 is kept on, the human activity detector 2 and the third relay are powered on, and the human activity detector 2 and the third relay are powered on. Electrical appliance 404 remains activated all the time and the automatic door remains open. When the human activity detector 2 detects human activity, it will continue to send signals to the second delay circuit 409 to restart the countdown. At this time, the third relay 404 continues to operate and the automatic door body 5 remains open. When the person leaves, the human activity detector 2 stops sending signals to the second delay circuit 409, and the second delay circuit 409 counts down normally. After the timing ends, the second relay 403 is released, and the human activity detector 2 and the third relay 404 lose power and stop working. The door opening signal of the automatic door body 5 is disconnected, and the automatic door body 5 is closed according to the program design. When the exit button 6 is not pressed and someone passes by the human activity controller, since the human activity controller is not powered on and does not work, the door opening signal will not be triggered, and the automatic door body 5 will not open.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
