[0026] Please see Figures 1 to 3 The automatic lifting door of this utility model includes a frame 10, a slide rail 20, a cylinder 30, a door body, a bracket 60, and a mounting base.

[0027] The frame 10 is used to install the door body, which is slidably mounted on the frame 10 to realize the opening or closing of the automatic lifting door. Specifically, in this embodiment, the frame 10 is inverted U-shaped.

[0028] The slide rail 20 is fixed to the frame 10 and is used to install the door body, allowing the door body to slide on the frame 10. Specifically, the slide rail 20 is arranged vertically, and there are two slide rails 20. The two slide rails 20 are parallel to each other and located on opposite sides of the frame 10.

[0029] The cylinder 30 is fixed to the frame 10. The cylinder 30 is arranged vertically, and there are two cylinders, which are located on both sides of the slide rail 20.

[0030] The door body includes an upper door 40 and a lower door 50. The upper door 40 is slidably mounted on the slide rail 20 and is located at the upper half of the frame 10. The lower door 50 is slidably mounted on the slide rail 20 and can slide from the bottom to the top of the slide rail 20. Specifically, both the upper door 40 and the lower door 50 are planar structures, located on different planes and parallel to each other, so that the mounting base of the upper door 40 is staggered from the sliding path of the lower door 50.

[0031] The bracket 60 is fixed to the top or inner wall of the lower door 50. In this embodiment, the bracket 60 is fixed to the inner wall of the lower door 50. The bracket 60 includes a fixing part 61 and a lifting part 62, which is fixedly connected to the fixing part 61 and is perpendicular to the fixing part 61. Specifically, the lifting part 62 is formed by bending the fixing part 61.

[0032] The mounting base is fixed to the frame 10. The mounting base is used to support the upper door 40 when the automatic lifting door is closed, so that the upper door 40 will not fall completely when the door loses power, thus reducing safety hazards.

[0033] When using the automatic lifting door, when the automatic lifting door opens, cylinder 30 drives the lower door 50 to slide upward relative to the frame 10. When it slides to the preset position, the lifting part 62 of the bracket 60 abuts against the bottom of the upper door 40, causing the lower door 50 to slide along with the upper door 40 until the door is fully open. When the automatic lifting door closes, cylinder 30 drives the lower door 50 to slide downward relative to the frame 10. Under the action of gravity, the upper door 40 slides down with the lower door 50 until the upper door 40 moves to the mounting base and lands on the mounting base. The lower door 50 continues to slide down until the automatic lifting door is fully closed.

[0034] The automatic lifting door of this application uses a cylinder 30 to drive the door body. It has a simple structure, is easy to install and has high safety. The door body is divided into two parts: the upper door 40 and the lower door 50. When the door loses power, the upper door 40 will not fall completely, reducing safety hazards.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
