In the present embodiment, the vertical lifting drive part 32 preferably adopts a conventional motor screw driving manner. The vertical lifting driving portion 32 may also adopt other driving methods, and any driving method may be adopted as long as the driving method can drive the conveying mechanism 40 to lift.

As described above, the goods are placed on the conveying mechanism 40, the truck body 30 is pulled to translate the goods from one place to another, the conveying mechanism 40 is driven to reciprocate in the vertical direction by the vertical lifting driving portion 32 to lift the goods, and then the transfer of the goods in the three-dimensional space is completed.

Next, a specific structure of the conveying mechanism 40 will be explained:

referring to fig. 3, 4 and 5, the conveying mechanism 40 includes: a base 100, a conveying body 200, and a folding driving part 300.

As shown in fig. 5, the conveying body 200 includes a carrier 210 and a conveyor belt 220, wherein the conveyor belt 220 surrounds the carrier 210 end to end.

One end of the carrier 210 is rotatably provided on the base 100.

As shown in fig. 6, the folding driving part 300 includes a folding driving motor 310 and a reduction gear set 320. The output end of the folding driving motor 310 is provided with a driving gear 311, the bearing frame 210 is provided with a driven gear 211, and the driving gear 311 is meshed with the driven gear 211 through a reduction gear set 320.

As shown in fig. 4, the base 100 has a vertical surface 110, the vertical surface 110 of the base 100 is provided with a receiving slot 111, and the folding driving portion 300 drives the carriage 210 to rotate, so that the carriage 210 is close to or far away from the vertical surface 110 of the base 100, and further the conveying body 200 is received in the receiving slot 111 or separated from the receiving slot 111.

The operation principle of the above-described conveying mechanism 40 will be explained below: the folding driving motor 310 drives the driving gear 311 at the output end to rotate, the driving gear 311 further drives the driven gear 211 to rotate through the reduction gear set 320, and since one end of the bearing frame 210 is rotatably disposed on the fixing frame 100 and the driven gear 211 is disposed on the bearing frame 210, the bearing frame 210 and the conveyor belt 220 thereon will turn around the base 100, and thus the conveying body 200 can be accommodated in the accommodating groove 111 or separated from the accommodating groove 111, thereby realizing the folding or unfolding of the conveying body 200. When the use of the conveying mechanism 40 is temporarily unnecessary, the conveying body 200 is folded so that the conveying body 200 is accommodated in the accommodating groove 111; when the conveying mechanism 40 needs to be used, the conveying body 200 is unfolded so that the conveying body 200 is located outside the storage groove 111.

Further, the conveying body 200 further includes a plurality of supporting rollers 230 (as shown in fig. 6), the supporting rollers 230 are sequentially arranged on the carrier 210 at intervals, and central axes of the supporting rollers 230 are parallel to each other. In this embodiment, two adjacent supporting rollers 230 are connected by a belt, so that the supporting rollers 230 can be linked. In other embodiments, two adjacent supporting rollers 230 are engaged and connected through a gear, so that the linking of the supporting rollers 230 can also be realized. The conveyor belt 220 is connected end to end around the plurality of supporting rollers 230, and the conveying body 200 further includes a conveyor belt driving portion (not shown) which is drivingly connected to one of the supporting rollers 230. Thus, the belt driving part drives one of the supporting rollers 230 to rotate, and the other supporting rollers 230 also rotate, so that the belt 220 performs a conveying motion.

The following explains the principle of the above-described structure of the conveying mechanism 40:

1. the vertical lifting driving part 32 is in driving connection with the conveying mechanism 40, and the vertical lifting driving part 32 drives the conveying mechanism 40 to lift in a reciprocating mode along the vertical direction, so that goods on the conveying mechanism 40 can be lifted, and the goods can be transferred in a three-dimensional space;

2. by arranging the conveying body 200, the conveying body 200 is provided with the conveyor belt 220, so that goods can be conveyed by the conveying function of the conveyor belt 220, and the loading or unloading function of the goods is realized;

3. since the conveying body 200 is provided with the conveying belt 220, the conveying belt 220 occupies a large amount of space, and therefore, the vertical surface 110 of the base 100 is provided with the accommodating groove 111, and the folding driving portion 300 drives the bearing frame 210 to rotate, so that the accommodating function of the conveying body 200 can be realized, and when the cargo handling vehicle is not needed to be used temporarily, the conveying body 200 is accommodated in the accommodating groove 111, thereby reducing the space occupation of the whole cargo handling vehicle.

In the process of rotating and lifting the conveying body 200, the center of gravity of the entire cargo truck may be changed, and the cargo truck may be easily tilted or even tilted. To better solve the technical problem, the cargo truck 20 further includes a telescopic support 50 (as shown in fig. 2), and the telescopic support 50 is disposed at the bottom of the vertical lifting body 31.

On one hand, before the conveying body 200 rotates or goes up and down, the telescopic support frame 50 is extended out of the vertical lifting main body 31, so that the whole cargo truck has a larger floor area, and the whole cargo truck is not easy to tip over, thereby effectively ensuring the use safety of products; on the other hand, after the conveying body 200 is completely rotated or lifted, the telescopic support 50 is retracted into the vertical lifting body 31, so that the cargo truck is more completely stored.
