When the voice control or the infrared sensor senses a preset signal, the signal is converted into an electric signal and transmitted to the control module, the control module sends a door opening signal to the first door opening mechanism 400 according to the content of the signal, after the first door opening mechanism 400 pops the door body 200 open by a small angle (the first door opening mechanism 400 acts to break the balance state between the door body 200 and the second door opening mechanism 500), the control module controls the second driving device to act, the universal shaft 502 drives the screw rod 503 to rotate, the screw rod 503 rotates to enable the screw nut 504 to move to the right side, namely to the direction of the door opening position 511, at this time, the screw nut 504 drives the spring 505 and the pull rope 506 to move rightwards, at this time, the spring 505 is in a loose state, and on the premise that the first door opening mechanism 400 pops open, the second driving device can control the door body 200 to further open until the door body is completely opened.
It should be understood that after the door 200 is fully opened, the position detecting device can detect that the screw nut 504 is at the door opening position 511, and at this time, it will send a signal to the control module, and the control module will control the screw nut 504 to return to the initial position 513 at the middle of the screw 503. When the screw nut 504 is at the initial position 513, the position detection device detects the position information of the screw nut 504, and sends a signal to the control module to control the second driving mechanism to stop working, so that the screw nut 504 is locked at the initial position 513, and further, preparation is made for subsequent other actions at any time.
When the door needs to be closed, a corresponding voice prompt is sent again or the infrared sensor is used for detecting and scanning (of course, the control module can be also in a key type, and the control module is directly controlled to perform door closing action), the door closing information is obtained and then sent to the control module, at the moment, the control module sends information to the second driving mechanism to drive the precession nut 504 to move towards the door closing position 512 until the door closing position 512 is reached, and the position detection device sends a signal to the control module to stop further movement until the door body 200 is completely closed. After the door body 200 is completely closed, the position detection device sends a signal to the control module again to control the precession nut 504 to move to the initial position 513, so that the precession nut 504 is locked at the initial position 513, and further, preparation is made for subsequent other actions at any time.
It should also be understood that the electric appliance can be operated manually, and a user can manually open and close the door, the screw nut 504 is not moved when the door is opened, the spring 505 is stretched, and the door body 200 can be stopped at any position under the influence of the tension of the spring 505.
