The door body of the telescopic door is made of high-quality aluminum alloy and ordinary square tubes, and is hinged using the parallelogram principle, which allows for flexible telescopic movement. In the prior art, electric telescopic doors are generally equipped with tracks when in use. However, after long-term use, a lot of debris will accumulate inside the existing tracks, which will cause the electric telescopic door to be stuck in the track and unable to move.

[0003] The existing Chinese patent CN213330550U discloses a sliding structure of an electric telescopic door, in which a connecting device, a positioning device and a pushing device are arranged to cooperate with each other, and a sliding rod for guiding is arranged in the track. When it is necessary to clean the debris in the track, the shovel plate and the moving rod can be installed on the moving rod, and then the holding rod is held to push the moving rod to move in the track, and the debris in the track can be shoveled out by the inclined surface of the shovel plate, which is convenient for centralized processing;

[0004] However, the sliding structure of the electric telescopic door still needs to be manually cleaned when cleaning the debris in the track, and the shovel plate and other structures need to be installed during cleaning, making the cleaning process more cumbersome. Utility Model Content

The plate 409 is slidably arranged in the track 2, and a blowing component 404 is arranged on the hollow block 408. The servo motor 402 drives the worm 403 to rotate, thereby driving the worm wheel 405 to rotate. The rotation of the worm wheel 405 drives the rotating shaft 406 to rotate, thereby driving the roller 407 to move, so that the roller 407 drives the electric telescopic door towing body 1 to move, thereby driving the mounting seat 401 to move. The movement of the mounting seat 401 drives the hollow block 408 to move, thereby driving the shovel plate 409 to move, and shovel out the garbage in the track 2, that is, the track 2 is cleaned during the movement of the electric telescopic door towing body 1, without manual cleaning, and the blowing component 404 is arranged to blow away the garbage shoveled by the shovel plate 409, without manual cleaning of the garbage on the shovel plate 409;

[0025] The blowing component 404 includes an airflow bin 4041 and an air outlet pipe 4045. The air outlet pipe 4045 is fixedly mounted on the left outer wall of the hollow block 408, and the interior of the air outlet pipe 4045 is connected to the interior of the hollow block 408. The airflow bin 4041 is fixedly mounted inside the electric telescopic door traction body 1. The right end of the airflow bin 4041 is connected to an air inlet pipe 4042. The right end of the air inlet pipe 4042 extends to the outside of the electric telescopic door traction body 1. The worm 403 passes through the left outer wall of the airflow bin 4041 through a bearing. The outer wall of the worm 403 is fixedly mounted with a fan blade 4043.

[0030] Working principle: when in use, when the electric telescopic door traction body 1 is needed to drive the entire electric telescopic door to move to the left, the servo motor 402 is turned on to drive the worm 403 to rotate, and then the worm wheel 405 is driven to rotate. The rotation of the worm wheel 405 drives the rotating shaft 406 to rotate, and then drives the roller 407 to rotate, so that the roller 407 drives the electric telescopic door traction body 1 to move to the left, and then drives the mounting seat 401 to move. The movement of the mounting seat 401 drives the hollow block 408 to move, and then drives the shovel plate 409 to move, and the garbage in the track 2 is shoveled out. When the worm 403 rotates, it drives the fan blade 4043 to rotate, generating a high-speed airflow, and the airflow enters the hollow block 408 from the connecting pipe 4044, and then enters the air outlet pipe 4045, and is blown out from the air outlet pipe 4045 to blow out the garbage generated by the shovel plate 409. When the electric telescopic door traction body 1 is needed to drive the entire electric telescopic door to move to the right, it is only necessary to turn on the servo motor 402 for reversal.
