It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In the present disclosure, the orientation words such as "up, down, front, back, left, right" are used for the convenience of description defined according to the direction of the drawing surface of the corresponding drawing, and "inner, outer" are defined according to the contour of the corresponding part itself. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, when the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0031] Referring to Figures 1 to 4 The present embodiment provides an airport shuttle vehicle, which comprises a vehicle body 10, a first belt conveying mechanism 20, a fixing frame, a lifting mechanism 40, and a plurality of second belt conveying mechanisms 50. The vehicle body 10 is provided with a storage cavity 11 and a vehicle door 12, and the bottom of the vehicle door 12 is hinged to the vehicle door 12. The first belt conveying mechanism 20 is installed on the inner side of the vehicle door 12 and extends along the height direction of the vehicle door 12. The fixing frame is fixed in the storage cavity 11. The lifting mechanism 40 is installed on the fixing frame. The plurality of second belt conveying mechanisms 50 are distributed along the longitudinal space of the storage cavity 11 and are arranged one-to-one with the plurality of second belt conveying assemblies. The second belt conveying mechanism 50 is installed on the fixing frame through the lifting mechanism 40, and the extension direction of the second belt conveying mechanism 50 is perpendicular to the extension direction of the first belt conveying mechanism 20. Both the first belt conveying mechanism 20 and the second belt conveying mechanism 50 are conveyor belt mechanisms. This continuous working mode significantly improves the efficiency of material conveying and reduces the waiting time of intermediate links.

[0032] It can be understood that the shuttle is parked next to the automatic loading system 200 (the automatic loading system 200 is prior art, only part of the structure of the automatic loading system 200 is shown in the figure), the door 12 is opened, the luggage 100 on the plane is automatically unloaded through the automatic loading system 200, then transported to the second belt conveyor mechanism 50 on the uppermost layer through the first belt conveyor mechanism 20 on the vehicle body 10, then the second belt conveyor mechanism 50 is started to drive the luggage 100 to leave the door 12, facilitating the entry of the next luggage 100 into the storage cavity 11, and after the first belt conveyor mechanism on the uppermost layer is filled with luggage 100, the lifting mechanism 40 connected with the first belt conveyor mechanism on the uppermost layer drives it to move upward, then the first belt conveyor mechanism 20 on the next layer moves upward to the original position of the first belt conveyor mechanism 20 on the uppermost layer under the drive of the lifting mechanism 40 connected therewith, and so on. The luggage 100 on the automatic loading system 200 will enter the corresponding first belt conveyor mechanism 20 one by one, and the luggage 100 does not need to be manually carried from the automatic loading system 200 to the shuttle, avoiding violent carrying and reducing the labor intensity of workers. At the same time, because multiple second belt conveyor mechanisms 50 are longitudinally distributed in the storage cavity 11, the problem of up-down compression of the luggage 100 in the storage cavity 11 is avoided, and the speed and height of the second belt conveyor mechanism 50 can be adjusted according to different situations such as the height of the plane cargo hold and the number of luggage 100, so as to better complete the luggage 100 loading and unloading task. The bar code scanner installed in the storage cavity 11 can scan the bar code of the airline, and provide real-time status information for the owner of the luggage 100 and the operator of the luggage 100, so as to eliminate the risk of loss of the luggage 100.

[0033] In an embodiment, referring to Figure 3 and Figure 4 The fixing frame includes four sliding grooves 30, and the four sliding grooves 30 are respectively arranged at the four corners of the storage cavity 11. The lifting mechanism 40 includes four linear motors 41 and four toothed clutches 60. Among them, the four linear motors 41 are respectively installed at the four corners of the second belt conveyor mechanism 50, and are in one-to-one sliding connection with the four sliding grooves 30. The four toothed clutches 60 are fixed on the four linear motors 41 one by one, so that the four corners of the second belt conveyor mechanism 50 can be lifted at the same time.

[0034] In an embodiment, the toothed clutch 60 is prior art, which will be briefly described below. The toothed clutch 60 at least includes a lower gear, a housing, an upper gear and a brake coil. Among them, the lower gear is fixed on the sliding groove 30. The upper gear is slidingly installed on the housing. The brake coil is installed on the linear motor 41, which is used to control the upper gear to extend into and out of the housing, so that the upper gear is separated or engaged with the lower gear.

[0035] It can be understood that when the linear motor 41 drives the second belt conveying mechanism 50 to move upward to a preset height, the brake coil is de-energized, the upper gear extends out of the shell, and the linear motor 41 moves downward to make the upper gear mesh with the lower gear to realize the braking of the linear motor 41 and avoid the downward sliding of the second belt conveying assembly. The brake coil is energized to make the upper gear extend into the shell and have no interference with the lower gear in the height direction, so that the linear motor 41 can slide downward.

[0036] In an embodiment, referring to Figure 3 , the number of the second belt conveying mechanisms 50 is three, which ensures the effective use of the storage cavity 11. Of course, in other embodiments, the number of the second belt conveying mechanisms 50 can be four, five or more than five.

[0037] In an embodiment, referring to Figure 2 , the route scanning engine 13, the display screen 14 and the charging port 15 are installed outside the vehicle body 10.
