[0045] like Figures 4-5 As shown, the working principle of the utility model is as follows:

[0046] The utility model discloses a lifting platform and door linkage device based on an unmanned aerial vehicle hangar. When the driving motor 604 rotates clockwise, the power is transmitted to the driving shaft 601-6 through the coupling 601-8. Because the lifting gear 601-5 and the active synchronous wheel 601-1 are connected to the active shaft 601-6, the lifting gear 601-5 and the active synchronous wheel 601-1 will rotate in the same direction as the motor 604. Because the lifting gear 601-5 is meshed with the lifting rack 19, when the lifting gear 19 rotates clockwise, it will drive the lifting rack 19 to move vertically upward, thereby realizing the lifting of the lifting platform 23.

[0047] Because the driven synchronous wheel 602-1 is mounted on the driven shaft 602-6, and the driven synchronous wheel 602-1 and the driving synchronous wheel 601-1 are meshed and connected through the synchronous belt 603, when the driving synchronous wheel 601-1 rotates clockwise, the driven synchronous wheel 602-1 will also rotate clockwise, thereby driving the door gear 602-5 to rotate in the same direction. Because the door gear 602-5 is meshed with the door rack 5, when the door gear 602-5 rotates clockwise, it will drive the door rack 5 to move horizontally to the right, thereby realizing the opening of the door 3.

[0048] When the driving motor 604 rotates counterclockwise, the power is transmitted to the driving shaft 601-6 through the coupling 601-8. Since the lifting gear 601-5 and the driving synchronous wheel 601-1 are connected to the driving shaft 601-6, the lifting gear 601-5 and the driving synchronous wheel 601-1 rotate in the same direction as the motor 604. Since the lifting gear 601-5 is meshed with the lifting rack 19, when the lifting gear 19 rotates counterclockwise, it drives the lifting rack 19 to move vertically downward, thereby realizing the descent of the lifting platform 23.

[0049] Because the driven synchronous wheel 602-1 is mounted on the driven shaft 602-6, and the driven synchronous wheel 602-1 and the driving synchronous wheel 601-1 are meshed and connected via the synchronous belt 603, when the driving synchronous wheel 601-1 rotates counterclockwise, the driven synchronous wheel 602-1 will also rotate counterclockwise, thereby driving the door gear 602-5 to rotate in the same direction. Because the door gear 602-5 is meshed with the door rack 5, when the door gear 602-5 rotates counterclockwise, it will drive the door rack 5 to move horizontally to the left, thereby achieving the closing of the door 3.

[0050] The utility model provides a lifting platform and cabin door linkage device based on an unmanned aerial vehicle hangar, which can realize the linkage of the lifting platform and the cabin door by controlling only one motor, thereby saving material costs and shortening operation time.

[0051] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.

[0052] Many other changes and modifications can be made without departing from the concept and scope of the utility model. It should be understood that the utility model is not limited to a specific embodiment, and the scope of the utility model is defined by the appended claims.
