[0034] Working principle: after the above automatic door 3 is installed, the transmission structure is located in the pre-set pit, which supports the automatic door 3; when a pedestrian passes through, the transmission structure controls the automatic door 3 to move to the second station along the first direction to open the first channel; after the pedestrian passes through, the transmission structure controls the automatic door 3 to move to the first station along the first direction to close the first channel; through the above structure, compared with the prior art, the transmission structure of the application is arranged at the bottom of the automatic door 3, which supports the automatic door 3, can make the center of gravity of the automatic door 3 lower, and reduces the shaking and vibration of the automatic door 3 in the running process; at the same time, the space at the bottom is larger than that at the top, which is convenient for installing the transmission structure, and further improves the overall appearance of the automatic door 3.

[0035] In some embodiments, the transmission structure comprises: a driving assembly and a sliding assembly arranged on the first frame 5; the sliding assembly is used for slidingly connecting the automatic door 3 with the first frame 5; the driving assembly is connected with the sliding assembly, and the driving assembly is used for driving the sliding assembly to drive the automatic door 3 to switch between the first station and the second station.

[0036] In some embodiments, the sliding assembly comprises:

[0037] The track 7 is fixed on the first frame 5, and the track 7 extends along the first direction, and the track 7 is located at the bottom of the automatic door 3;

[0038] The connecting plate 9 is located on one side of the track 7, the connecting plate 9 is in inverted L-shaped structure, the top of the connecting plate 9 is fixedly connected with the bottom of the automatic door 3, and the side close to the track 7 of the connecting plate 9 is provided with the roller 8, and the roller 8 is in rolling connection with the track 7.

[0039] Specifically, as shown in Figure 2 The top of the connecting plate 9 is fixedly connected with the bottom of the automatic door 3 to support the automatic door 3;

[0040] Specifically, the length of the track 7 is equal to the distance from the first station to the second station; in this embodiment, the aluminum profile 6 is arranged on the first frame 5 to form the track 7; the driving assembly drives the roller 8 to move in the track 7 to drive the automatic door 3 to switch between the first station and the second station.

[0041] In some embodiments, the driving assembly comprises: a motor 10 and a driven wheel, the motor 10 and the driven wheel are arranged in the first direction in the first frame 5, and the motor 10 is located on the side away from the track 7 of the connecting plate 9; the driving end of the motor 10 is connected with a driving wheel 13, and the driven wheel and the driving wheel 13 are connected through a belt transmission; the belt is fixedly connected with the connecting plate 9.

[0042] Specifically, the belt drive is a mechanical transmission method that relies on the friction between the belt and the driving wheel 13 and the driven wheel to transmit power. When the driving wheel 13 rotates under the drive of the motor 10, the belt moves by the friction between the belt and the driving wheel 13, and the driven wheel rotates by the friction between the belt and the driven wheel, thereby achieving power transmission from the driving wheel 13 to the driven wheel.

[0043] Specifically, the belt has a certain elasticity and can absorb and buffer vibrations during transmission. For example, when the motor 10 starts or stops, an instantaneous impact may occur, and the belt can effectively reduce the impact of this impact on the entire transmission system, making the rotation of the driven wheel more stable. This is very important for the smooth operation of the automatic door 3, because if there is no buffer during frequent opening and closing of the automatic door 3, it may produce a lot of noise and vibration, affecting the service life and user experience.
