[0023] Please refer to Figure 2 and Figure 5In this embodiment, the blower assembly includes a dual-axis motor 16. The dual-axis motor 16 is disposed within the groove 4. The output shafts at both ends of the dual-axis motor 16 are connected to a drive shaft 17. A second bearing seat 18 is disposed at the bottom of the groove 4. A rotating shaft 19 is rotatably connected within the second bearing seat 18. A fan 20 is fixedly connected to the outer wall of the rotating shaft 19. A transmission structure is provided between the rotating shaft 19 and the drive shaft 17. The transmission structure includes a drive bevel gear 21. The outer wall of the drive shaft 17 is fixedly connected to the fan 20. A driving bevel gear 21 is fixedly connected to the outer wall of the rotating shaft 19, and a driven bevel gear 22 is fixedly connected to it. The driving bevel gear 21 and the driven bevel gear 22 are meshed together. A slot 24 is provided on the side end of the left sliding door 3, and a locking block 23 adapted to the slot 24 is integrally provided on the side end of the right sliding door 3. The locking block 23 is inserted into the slot 24. A matching magnet is provided in both the locking block 23 and the slot 24, and the locking block 23 and the slot 24 are magnetically connected. The dual-axis motor 16 is the power source of the blower assembly. The dual-axis motor 16 is characterized by having output shafts at both its left and right ends, enabling it to drive transmission structures in two directions simultaneously. The second bearing seat 18 is used to support and fix the rotating shaft 19, which is a component connecting the fan blades 20 and the transmission structure. The fan 20 is fixedly connected to the outer wall of the rotating shaft 19. When the rotating shaft 19 rotates, the fan 20 rotates accordingly, generating airflow. The transmission structure is a component connecting the drive shaft 17 and the rotating shaft 19, responsible for transmitting the power of the dual-axis motor 16 to the rotating shaft 19. When the drive shaft 17 rotates, the power is transmitted to the rotating shaft 19 through the meshing of the driving bevel gear 21 and the driven bevel gear 22, causing the fan 20 to rotate. The shape of the slot 24 matches the locking block 23. When the two sliding doors 3 are closed, the locking block 23 is inserted into the slot 24, achieving a tight connection between the sliding doors 3. Both the slot 24 and the locking block 23 are equipped with matching magnets, which further enhance the sealing and stability between the sliding doors 3 through magnetic connection.

[0024] During operation, after starting the high-voltage brushless motor 8 and the dual-axis motor 16, the high-voltage brushless motor 8 drives the lead screw 13 to rotate. Utilizing the interaction between the threads, the moving seat 14 pushes the sliding door 3 to move under the guidance of the guide rod 15. At the same time, the slider 6 at the lower end of the sliding door 3 slides along the guide rail 5 to ensure the smooth movement of the sliding door 3. When the two sliding doors 3 are closed, the locking block 23 is precisely inserted into the locking slot 24 to achieve a tight closure between the sliding doors 3. The built-in magnet further enhances the sealing and stability between the sliding doors 3 through magnetic attraction.

[0025] At the same time, the dual-axis motor 16 drives the transmission shaft 17 to rotate. The transmission shaft 17 transmits power to the rotating shaft 19 through the meshing of the active bevel gear 21 and the driven bevel gear 22, thereby driving the fan 20 to rotate and providing a cooling effect for people passing through the door panel 2.

[0026] Through the above steps, compared with traditional motor-driven sliding door operators, this solution uses a high-voltage brushless motor 8 as the power source, which effectively improves working efficiency, reduces noise, and significantly extends service life. At the same time, the coordinated work of the sliding component and the blowing component not only ensures the smooth and precise movement of the sliding door 3, but also drives two fans 20 to run simultaneously, bringing a cool experience to people passing through the door panel 2. This solves the problem that the sliding door operator uses a brushed motor and the imperfect drive structure is prone to causing the sliding door 3 to shake, and also lacks a blowing function, making it unable to provide a cool experience in high-temperature environments.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
