fig. 2 is a schematic structural diagram of an automatic door opening and closing device according to the present invention.

Detailed Description

In order to better understand the technical scheme of the utility model, the following detailed description is made on the embodiments provided by the utility model in combination with the accompanying drawings.

Example one

As shown in fig. 1, it can be understood that the present embodiment provides an automatic door opening and closing device, including: the device comprises an electric device 1, a magnetic lock head 2, an absorption plate 3 and a door body 4, wherein the electric device 1 is fixedly connected with the magnetic lock head 2, and the absorption plate 3 is fixedly connected with the door body 4; the suction plate 3 is made of a magnetic metal and can generate magnetic force with the magnetic lock head 2, and the magnetic lock head 2 and the suction plate 3 are interacted by magnetic force.

The suction plate 3 in this embodiment is fixed on the door body 4, and the door body 4 drives the suction plate 3 to be far away from or close to the magnetic lock head 2 when rotating around the door shaft. The door body 4 and the cabinet body 5 are opened and closed by electromagnetic force between the magnetic lock head 2 and the suction plate 3, the suction plate 3 in the embodiment is a soft iron suction plate 3 and is made of soft iron, and other magnetism-attracting metals can be used in other embodiments to meet the electromagnetic force between the door body and the magnetic lock head 2.

Example two

Furthermore, the device also comprises a control device, and the magnetic lock head 2 and the electric device 1 are both connected with the control device. The electric device 1 is fixed on the cabinet body 5, and the control device controls the electric device 1 to stretch or reciprocate. The control device controls the power-on and power-off of the magnetic lock head 2 so as to control the generation and annihilation of the electromagnetic force between the strong magnetic lock head 2 and the suction plate 3. A stroke control module is arranged in the electric device 1 and can sense the upper limit position and the lower limit position of the magnetic lock head 2. And a distance induction module is arranged in the magnetic lock head 2 and can induce whether the suction plate 3 is positioned in a magnetic action range.

As shown in fig. 2, the electric device 1 is fixed on the cabinet 5, and the electric device 1 can stretch or reciprocate under the control of the control device to drive the magnetic lock head 2 to move forward or backward. Specifically, when the door is opened, the control device controls the magnetic lock head 2 to be powered off, the electromagnetic force between the magnetic lock head 2 and the suction plate 3 disappears, meanwhile, the control device controls the electric device 1 to drive the magnetic lock head 2 to move forward, namely, to the right side of the drawing 1, so that the cabinet door is pushed open, and at the moment, a user can further pull the door open by only a small force.

When the door is closed, the user pushes the door body 4 to move towards the door closing direction by hand. When the suction plate 3 is close to the magnetic lock head 2, the distance sensing module senses the approach of the suction plate 3, the control device controls the magnetic lock head 2 to be electrified to generate electromagnetic suction to suck the suction plate 3, the control device simultaneously sends a retreating instruction to the electric device 1, the door body 4 is further tensioned under the action of the electric device 1 until the electric device 1 stops moving at a corresponding position, and the cabinet door is completely closed.

The electric device 1 adopts 12V direct current, and the expansion and contraction of the electric device 1 are controlled by controlling the positive and negative of the current. The magnetic lock head 2 adopts 12V direct current. In other embodiments, currents of 24V, 48V, etc. may also be used.

While the automatic door opening and closing device provided by the embodiment of the present invention has been described in detail, those skilled in the art will appreciate that the utility model is not limited to the above description, and that various modifications, additions, substitutions, and substitutions are possible, without departing from the scope and spirit of the utility model as disclosed in the accompanying claims.
