DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 5 A foldable automatic door structure includes a door frame 3 and a motor. Both sides of the door frame 3 are rotatably connected with a second door panel 2. One side of the second door panel 2 is rotatably connected with a first door panel 1. A slide groove 13 is provided at the top of the door frame 3. A slide rod 5 is slidably connected in the slide groove 13. Two first sliders 6 are slidably connected to the outer side of the slide rod 5. A groove body 9 is provided inside the door frame 3. Two bidirectional threaded rods 8 capable of driving the second slider 7 to move are rotatably connected inside the groove body 9. A card slot 19 is provided inside the second slider 7. Two magnetic blocks 18 are fixed to the top of the slide rod 5 by bolts, and the magnetic blocks 18 are inserted into the card slot 19. The material of the second slider 7 is iron, so that the magnetic block 18 can attract the second slider 7, so that the magnetic block 18 can be stably inserted in the card slot 19. A slot 21 is provided at the bottom of the first slider 6, a protrusion 20 is fixed at the top of the first door panel 1 by bolts, and the protrusion 20 is inserted into the slot 21, a pull rope 11 is installed at one end of the slide rod 5, a cavity 10 is provided on one side of the door frame 3, and the pull rope 11 is located inside the cavity 10. When the motor is damaged, the staff pulls the pull rope 11 to move the slide rod 5 downward along the slide groove 13, the spring 15 contracts, and at the same time the slide rod 5 drives the first slider 6 to move downward, so that the protrusion 20 completely enters the slot 21, and at the same time the slide rod 5 moves downward to separate the magnetic block 18 from the card slot 19. At this time, the top of the first door panel 1 is not restricted, and the staff can manually open the folding door by pulling the door handle. Two reset components are provided between the top of the door frame 3 and the slide rod 5.

[0025] In the present invention, it should be noted that the motor is fixed to an outer wall of one side of the door frame 3 by bolts, and one end of the motor output shaft passes through the door frame 3 and is fixed to the bidirectional threaded rod 8. The reset assembly includes a fixing plate 14, and the fixing plate 14 is fixed to the inner walls on both sides of the door frame 3 by bolts. A positioning column 16 is fixed to the top of the fixing plate 14 by bolts, and the positioning column 16 is slidably connected to the slide bar 5. The positioning column 16 can guide the slide bar 5 so that it can move the cabinet stably. A spring 15 is sleeved on the outer side of the positioning column 16 for facilitating the resetting of the slide bar 5, and the two ends of the spring 15 are respectively fixed to the fixing plate 14 and the slide bar 5. A torsion spring 17 is sleeved on the top of the first door panel 1, and the two ends of the torsion spring 17 are respectively sleeved on the first door panel 1. The door panel 1 and the second door panel 2 are fixed, and the torsion spring 17 can move the connection between the first door panel 1 and the second door panel 2 to the side closer to the person. An installation opening is opened on one side of the rotating door frame 3, and the top of the installation opening is rotatably connected with a cover plate 4 for shielding the counterweight 12. A counterweight 12 is provided at one end of the pull rope 11, and the counterweight 12 is located inside the cavity 10 and on the side of the installation opening. The counterweight 12 can make the pull rope 11 in a vertical state, which is convenient for the staff to pull. A door handle is fixed to one side of the first door panel 1 by bolts, and a sensing device is installed on the top of the door frame 3, and the sensing device is electrically connected to the motor. The sensing device is used to sense whether a person or object is approaching, and the motor is controlled to start when the approach of a person or object is sensed.

[0026] Working principle: when the folding door needs to be opened automatically, the sensing device is used to sense whether there is a person or an object approaching. When it is sensed that someone or an object is approaching, the motor is controlled to start, and the motor rotates to make the bidirectional threaded rod 8 drive the second slider 7 to move on both sides respectively, so that the first slider 6 drives to move to both sides along the slide bar 5 respectively. At this time, the first door panel 1 gradually approaches the second door panel 2, and the torsion spring 17 is deformed until the first door panel 1 is folded onto the second door panel 2, forming an opening action. When the motor is damaged, the staff opens the cover plate 4, reaches into the installation port to hold the counterweight 12, and then pulls the counterweight 12, so that the pull rope 11 pulls the slide bar 5 to move downward along the slide groove 13, the spring 15 contracts, and at the same time the slide bar 5 drives the first slider 6 to move downward, so that the protrusion 20 completely enters the notch 21, and at the same time the slide bar 5 moves downward to separate the magnetic block 18 from the card slot 19. At this time, the top of the first door panel 1 is not restricted, and the staff can manually open the folding door by pulling the door handle.

[0027] In addition, the terms "disposed", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
