Detailed Description

The above objects, features and advantages of the present invention will be more clearly understood and the present invention will be explained in more detail with reference to the accompanying drawings 1 to 7 and the detailed description thereof.

The automatic corner opening and closing door system for public buildings adopted by the embodiment comprises a door leaf 1, a door frame, a connecting rod 8, an upper swing arm 4, a lower swing arm 16, a side rotating shaft 6, a driver 10, a controller 11, a magnetic lock 13 and a coded lock 12. The top of the door leaf 1 is connected with an upper connecting seat 2 and a support 7 through screws, the door leaf 1 is connected with one end of an upper swing arm 4 through an upper bearing sleeve component 3 connected with the upper connecting seat 2, and the other end of the upper swing arm 4 is fixedly connected with the top of a side rotating shaft 6 through an upper clamping screw 5. The connecting rod 8 is connected with the bracket 7 by a first spherical bearing at one end, and the connecting rod 8 is connected with a bracket plate 9 fixed on the outer wall body by a second spherical bearing at the other end. The connecting rod 8, the upper swing arm 4, the door leaf 1 and the side rotating shaft 6 in the embodiment form a four-bar structure. When the driver 10 receives a door opening signal, the side rotating shaft 6 is driven to rotate counterclockwise, and the door leaf 1 is pulled by the connecting rod 8 to rotate clockwise around the center of the upper connecting seat 2, so that the door leaf 1 is moved from a closed state to an open position. The controller 11 will send a signal to the driver 10 according to the delay time set by the user under the control of its internal delay circuit, and drive the side rotating shaft 6 to rotate clockwise, and the door leaf 1 rotates clockwise around the center of the upper connecting seat 2 under the pulling of the connecting rod 8, so that the door leaf 1 rotates automatically from the open state to the closed position.

In this embodiment, a load-bearing assembly is disposed at the bottom of the door leaf 1, and mainly comprises a lower connecting seat 14, a lower bearing sleeve assembly 15 and a lower swing arm 16. A lower bearing sleeve assembly 15 connected on the lower connecting seat 14 is connected with one end of a lower swing arm 16, and the other end of the lower swing arm 16 is fixedly connected with the bottom of the side rotating shaft 6 by a lower clamping screw 17. The top of the side rotating shaft 6 is connected with a driver 10 and rotates under the control of the driver 10, the connecting rod 8 rotates along with the side rotating shaft 6 and drives the door leaf 1 to rotate by taking the upper connecting seat 2 and the lower connecting seat 14 as centers, and the door leaf 1, the upper swing arm 4 and the lower swing arm 16 are in a rotating fit state.

In the embodiment, a magnetic lock 13 is connected to the top of the door frame, and both the magnetic lock 13 and the actuator are respectively connected to the output end of the controller 11 for receiving the control signal of the controller 11. The wall body at the closed position of the door leaf is provided with a coded lock 12, and the coded lock 12 in the embodiment is connected with the input end of the controller 11 and is used for providing a door leaf opening signal to the controller 11. A button 18 is also mounted on the wall opposite to the combination lock 12, and the button 18 is also connected with the input end of the controller 11 for outputting a door opening signal to the controller 11. The controller 11 adopted in the embodiment is a commercially available 329 door operator circuit board, and the driver model is a commercially available 42 gpp bldc4260 permanent magnet brushless direct current planetary reduction motor.

The working principle of the automatic corner door opening and closing system in the embodiment is as follows:

when driver 10 received the signal of opening the door, can drive side rotation axis 6 anticlockwise rotation, door leaf 1 can be round connecting seat 2 center clockwise rotation under the pulling of connecting rod 8, and door leaf 1 can be from closed condition to the open position of door leaf, and opening and closing of door leaf 2 and pedestrian march and the position of standing do not interfere mutually, have solved the interference problem of automatic vertical hinged door.

When the coded lock 12 receives a door opening signal, the door opening signal is transmitted to the controller 11, the controller 11 sends a door opening signal to the driver 10 while sending an unlocking signal to the magnetic lock 13, the driver 10 drives the rotating shaft 6, the rotating shaft 6 drives the upper swing arm 4 and the lower swing arm 16 to rotate anticlockwise, and meanwhile the connecting rod 8 pulls the door leaf 1 to enable the door leaf 1 to rotate clockwise, so that the action of a door leaf opener is completed; when the pedestrian passes, the door leaf automatically completes the closing action and is restored to the closing state.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
