Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the door comprises a door frame 1, a driving piece 11, a groove 12, a guide rod 13, a screw 14, a sliding door 2, a hinge 21, a limiting groove 22, a first guide block 23, a rotating door 3, a permanent magnet 4 and a sleeve 41.

Example 1

An automatic folding door, as shown in figure 1, comprises a door frame 1, a rotating door 3, a sliding door 2, a power unit and an ejecting unit, wherein the rotating door 3 is connected with the sliding door 2 through a hinge 21, so that the rotating door 3 can rotate relative to the sliding door 2. The right end of the rotating door 3 is hinged with the door frame 1. The upper end of door frame 1 is equipped with recess 12, as shown in fig. 2, the power unit includes screw rod 14, driving piece 11, guide bar 13 and first guide block 23, recess 12 extends along the width direction of door frame 1, and the opening of recess 12 is towards sliding door 2 and revolving door 3, guide bar 13, screw rod 14 and first guide block 23 all are located recess 12, and screw rod 14 and guide bar 13 all extend along the direction of recess 12, screw rod 14 all run through first guide block 23 with guide bar 13, the both ends of guide bar 13 are all through bolt fastening on the recess 12 lateral wall. The first guide block 23 can slide relative to the guide rod 13, the screw 14 and the first guide block 23 in this embodiment form a ball screw structure, the driving member 11 is fixed on the door frame 1 by a wood screw, the driving member 11 in this embodiment adopts a forward and reverse rotation motor, the right end of the screw 14 penetrates through the right wall of the groove 12, and the output shaft of the driving member 11 is connected with the right end of the screw 14 by a coupler for driving the screw 14 to rotate. The first guide block 23 is hinged to the left end of the sliding door 2, and when the first guide block 23 slides to the right, the sliding door 2 can rotate relative to the first guide block 23.

One side that recess 12 was kept away from to door frame 1 is equipped with the guide way, and the guide way is on a parallel with recess 12, is equipped with the second guide block in the recess 12, and the second guide block is relative with first guide block 23 and articulated with the left end of sliding door 2, and the second guide block can lead the slip of sliding door 2 with the guide way cooperation.

The left end of revolving door 3 is equipped with pops out the unit, pops out the unit and includes electro-magnet and permanent magnetism piece 4, is equipped with the holding tank on the door frame 1 in this embodiment, and the electro-magnet passes through the wood screw to be fixed in the holding tank, and permanent magnetism piece 4 is located the left end of revolving door 3 and is relative with the electro-magnet. The lower end of the permanent magnet 4 extends into the rotating door 3, the electromagnet in the embodiment is a direct current electromagnet, and after the electromagnet is electrified, the magnetic pole of one end of the electromagnet close to the permanent magnet 4 is the same as that of one end of the permanent magnet 4 facing the electromagnet, and the permanent magnet 4 is repelled. One end of the permanent magnet 4, which is positioned outside the rotating door 3, is sleeved with a sleeve 41, and the sleeve 41 is fixed on the rotating door 3 through a wood screw to protect the permanent magnet 4. The right end of the sliding door 2 is provided with a limiting groove 22, the opening of the limiting groove 22 faces the door frame 1, and the limiting groove 22 is opposite to the sleeve 41 and is used for accommodating the sleeve 41 and the permanent magnet 4. The sleeve 41 in this embodiment is externally sleeved with an annular elastic layer, and the elastic layer in this embodiment is made of butadiene acrylonitrile rubber, so as to prevent the sleeve 41 from directly contacting with the side wall of the limiting groove 22, and protect the sleeve 41.

The specific implementation process is as follows:

initially, the first sliding block and the second sliding block are located at the left end of the door frame 1, the sliding door 2 and the rotating door 3 are both parallel to the door frame 1, and the sliding door 2 and the rotating door 3 are closed at this time. When the door needs to be opened, the driving piece 11 and the electromagnet are started, the electromagnet repels the permanent magnet 4, the rotating door 3 is pushed to one side far away from the door frame 1, and the sliding door 2 and the rotating door 3 are rotated into a V shape. Meanwhile, the driving piece 11 drives the screw rod 14 to rotate, so that the first sliding block slides rightwards to drive the sliding door 2 to rotate clockwise and the rotating door 3 to rotate anticlockwise, and finally the sliding door 2 and the rotating door 3 rotate to be parallel to each other, so that the rotating angles of the sliding door 2 and the rotating door 3 are increased, and the situation that the sliding door 2 and the rotating door 3 obstruct pedestrians is avoided.

As shown in fig. 3, when the sliding door 2 and the rotating door 3 are rotated to be parallel to each other, the sleeve 41 is inserted into the stopper groove 22. When the sliding door 2 and the rotating door 3 are pushed transversely, the sliding door 2 and the rotating door 3 are enabled to rotate clockwise or anticlockwise simultaneously, due to the fact that the rotating centers of the sliding door 2 and the rotating door 3 are different, relative movement occurs between the sleeve 41 and the limiting groove 22, the limiting groove 22 limits movement of the sleeve 41, rotation of the sliding door 2 and the rotating door 3 is limited, and reduction of door opening amplitude caused by overlarge rotating amplitude of the sliding door 2 and the rotating door 3 is avoided.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
