the door body 100 rotates around the vertical shaft, is arranged along the vertical direction and is rotatably connected with the first rotating hole, the door body 100 is provided with a connecting seat 110, the connecting seat 110 is fixed on the front side wall of the door body 100, and the connecting seat 110 is provided with a vertically arranged first rotating shaft;

the driving mechanism comprises a rotary driving device 260, a crank 210, a connecting rod 220, an output rod 250, a sliding rail 230 and a sliding block 240, wherein the rotary driving device 260 and the sliding rail 230 are both installed on a second wall surface and are relatively fixed with a hinged support, the sliding block 240 slides along the sliding rail 230, a second rotating shaft 242 and a third rotating shaft 241 are respectively arranged on the front side and the rear side of the sliding block 240, the second rotating shaft 242 and the first rotating shaft are arranged in the same direction, the axial direction of the third rotating shaft 241 is not parallel to the axial direction of the second rotating shaft 242, a driving connecting hole is formed in the front side of the crank 210, a hinge joint is formed in the rear side of the crank 210 and one side of the connecting rod 220, the other side of the connecting rod 220 is hinged with the third rotating shaft 241, one side of the output rod 250 is hinged with the;

the sensor 300 is arranged on one side of the door body 100, the sensor 300 is relatively fixed to the hinged support, and the sensor 300 is configured to sense that the rotary driving device 260 is started when a person approaches the door body 100.

According to the device, the sensor 300 and the driving mechanism are arranged, when the sensor 300 senses that a human body approaches the door body 100, the rotary driving device 260 drives the rotary door body 100 to be connected by utilizing the crank 210, the connecting rod 220, the output rod 250, the sliding rail 230 and the sliding block 240, so that people do not need to contact the door or the door handle when entering or exiting, the infection risk is reduced, and the sanitary condition is improved; the device has simple and compact structure, and the application of the device to transform the prior rotary door body 100 into the induction door has small engineering quantity and low transformation cost; because the crank mechanism is adopted, the crank 210 is driven by the rotation driving device 260 to rotate for 360 degrees, and the torsional stress born by the crank 210 is uniform and is not easy to damage.

Specifically, the axis of the second rotating shaft 242 and the axis of the third rotating shaft 241 are perpendicular to each other.

The rotation driving device 260 may be a servo motor, the servo motor is electrically connected to an external power source, and the servo motor has an advantage of adjustable rotation speed.

One side of the sliding block 240 is provided with a first lug, the third rotating shaft 241 is provided on the first lug, the third rotating shaft 241 extends to the side of the sliding rail 230, and the distance from the third rotating shaft 241 to the sliding rail 230 is less than the thickness of the connecting rod 220. Therefore, when the connecting rod 220 is directly sleeved on the third rotating shaft 241, because the distance from the third rotating shaft 241 to the sliding rail 230 is smaller than the thickness of the connecting rod 220, the connecting rod 220 cannot be separated from the third rotating shaft 241 under the limiting action of the sliding rail 230, and an external limiting member is not required to be additionally arranged to prevent the connecting rod 220 from being separated from the third rotating shaft 241, so that the assembly is simpler.

The sensor 300 is used in conjunction with a conventional controller through which a signal connection to the rotary drive 260 is made. A CCS module including a 51-chip microcomputer and a motor driving module may also be employed. When a person is ready to walk through the door opening to the pedal, the gravity sensor senses that the weight is changed and transmits the weight to the CSS control module, and the CSS control module feeds back a signal to the rotary driving device 260 to drive the rotary driving device 260 to rotate forward to drive the door body 100 to slide to open the door opening. The CCS control module may further include a timing module, and after the CCS control module drives the rotation driving device 260, the timing module counts down a certain time to enable the rotation driving device 260 to turn over to drive the door body 100 to slide to close the door opening.

The sensor 300 may also be two proximity switches, and the two proximity switches are respectively installed at the front side and the rear side of the door body 100. In particular, the proximity switch may be fixed to the wall on the side that is first opened when sliding. The action principle is similar to that of the gravity sensor, and the difference is only that the signal is changed from the gravity sensor to the proximity switch, which is not described in detail herein.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments, but is capable of various changes and modifications without departing from the spirit of the invention.
