(rotated by 0 to 90 degree directions) when door body 200 is in door opening action：

Control board 3 controls reducing motor 2 to drive driving gear 41 and the synchronous even acceleration rotation of driven gear 42, driven Power transmission shaft 43 on gear 42 drives upper door-hinge 300 to carry out even acceleration and rotates forward, until upper door-hinge 300 drives door body 200 to revolve Go to the first dislocation 524, that is, under the synchronization of universal driving shaft 51 drives, kicker magnet rotates to the first dislocation rotating disk 54 524, the kicker magnet being integrated in rotating disk 54 is located at directly over the Hall element of the first dislocation 524, now, Hall element The rotation in sensor magnet magnetic field changes and exports the corresponding signal of telecommunication to control board 3；

Control board 3 will export corresponding control signal to reducing motor 2 after Electric signal processing, so that the described electricity that slows down Machine 2 passes through driving gear 41, driven gear 42 drives that upper door-hinge 300 is even is rotated in deceleration, until upper door-hinge 300 drives door body 200 Rotate to hindering position, that is, under the synchronization of universal driving shaft 51 drives, kicker magnet rotates to hindering position 521 rotating disk 54, integrated It is located in the kicker magnet in rotating disk 54 and hinder directly over the Hall element of position, now, Hall element sensor magnet magnetic field Rotation changes and exports the corresponding signal of telecommunication to control board 3；

This control board 3 will export corresponding obstruction signal to reducing motor 2 after Electric signal processing, so that described deceleration Motor 2 controls described door body 200 to be paused or reverse rotation action, until after exceeding Preset Time, this control board 3 continues Continuous control reducing motor 2 drives upper door-hinge 300 to drive door body 200 to rotate forward to enabling extreme position 522 stopping.

When door body 200 is opened, carry out even acceleration rotation mode from slow to fast it is therefore an objective to when can reduce the wait of pedestrian Between, door body 200 rotates to the even mode that is rotated in deceleration during the first dislocation 524, carrying out from fast to slow, until it reaches limit position Put stopping, cushioning effect can be played, prevent door body 200 knocking door case, access door is caused damage.

(rotated from 90 degree to 0 degree direction) when door body 200 is in and closes the door action：

Control board 3 controls reducing motor 2 to drive driving gear 41 and the synchronous even acceleration inversion rotation of driven gear 42, Power transmission shaft 43 on driven gear 42 drives upper door-hinge 300 to carry out even acceleration inversion rotation (with respect to enabling direction of rotation Speech), until upper rotating shaft drives door body 200 to rotate to the second dislocation 525, that is, rotating disk 54 is in the synchronization drive of universal driving shaft 51 Under, kicker magnet rotates to the second dislocation 525, and the kicker magnet being integrated in rotating disk 54 is located at the second dislocation 525 Directly over Hall element, now, the rotation in Hall element sensor magnet magnetic field changes and exports the corresponding signal of telecommunication to controlling electricity Road plate 3；

This control board 3 will export corresponding obstruction signal to reducing motor 2 after Electric signal processing, so that described deceleration Motor 2 control by driving gear 41, driven gear 42 drive upper rotating shaft is even is rotated in deceleration, until upper rotating shaft drives door body 200 Rotate to another obstruction position, that is, under the synchronization of universal driving shaft 51 drives, kicker magnet rotates to another obstruction position rotating disk 54, The kicker magnet being integrated in rotating disk 54 is located at directly over the Hall element hindering position, now, Hall element sensor magnet magnetic The rotation of field changes and exports the corresponding signal of telecommunication to control board 3；

This control board 3 will export corresponding obstruction signal to reducing motor 2 after Electric signal processing, so that described deceleration Motor 2 controls described door body 200 to be paused or rotated forward action, until after exceeding Preset Time, this control board 3 continues Continuous control reducing motor 2 drives upper rotating shaft to drive door body 200 to rotate forward to extreme position 523 of closing the door stopping.

When door body 200 is closed, carry out even acceleration rotation mode from slow to fast first it is therefore an objective to return, door body can be accelerated 200 rotate to close to extreme position 523 of closing the door the second dislocation 525 when, carry out the even side of being rotated in deceleration from fast to slow Formula, until it reaches extreme position stops, and equally can play cushioning effect, prevent door body 200 knocking door case, access door is caused Infringement, simultaneously, it is to avoid produce the generation of clamping accident, ensures pedestrian safety.

Additionally, this product is under deceleration regime in door body 200, so that door body 200 is paused or reverse rotation process, can subtract The little infringement to parts such as reducing motor 2, gear, upper and lower rotating shafts is additionally it is possible to ensure that door body 200 is subject to the thrust of strong wind, Men Ye The situation of knocking door case will not occur；Avoid sending larger sound, the people of surrounding is caused to perplex.

Preferably, in the present embodiment, described obstruction signal is the reverse rotation signal controlling described reducing motor 2.

Preferably, also include state memorization module in the present embodiment, it is connected with described control board 3, this state is remembered Recall module for the described position of real time record door body 200.

Preferably, the access door that the present embodiment provides needs to pass in and out the pedestrian of door body 200 using infrared sensor detection, should Infrared sensor is connected with control board 3, and when door body 200 unprofessional person is detected, infrared sensor sends a command to control Circuit board 3, and start the operating that control board 3 drives reducing motor 2, state memorization module is opened, in real time memory door body 200 Rotation present position.

In the present embodiment, control board 3 is also integrated with signal detector, and it is used for detecting that described reducing motor 2 drives The value of electrical signals exporting during upper door-hinge 300 rotation, and compare with threshold value default in signal detector,

When the value of electrical signals of described reducing motor 2 output is more than preset threshold range, described signal detector output signal Reversely rotated to driving means.

The effect arranging this signal detector is, when door body 200 normal rotation, once being subject to artificial impulsive contact force, permissible Immediately reversely rotated, more effectively protection equipment will not therefore be damaged, meanwhile, it is capable to ensure the safety of pedestrian.

Finally it should be noted that：Various embodiments above is only in order to illustrating the technical solution of the utility model, rather than it is limited System；Although being described in detail to this utility model with reference to foregoing embodiments, those of ordinary skill in the art should Understand：It still can be modified to the technical scheme described in foregoing embodiments, or to wherein some or all of Technical characteristic carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this practicality new The scope of type each embodiment technical scheme.
