[0004] However, during the loading and unloading process, the transfer vehicle needs to use manual labor to carry the goods. Workers need to frequently bend and lift, which can easily lead to physical fatigue and injury. Accidents such as cargo falling and collision may also occur during the loading and unloading process, posing a threat to the workers' personal safety. In addition, the speed and strength of manual operation are limited, resulting in high time costs and reducing the efficiency of loading and unloading of the transfer vehicle. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1-Figure 7 As shown, an unmanned transport vehicle convenient for loading and unloading goods comprises a vehicle body 100 and a vehicle compartment 101. The vehicle compartment 101 is a hollow structure with an opening at one end. A movable door 102 is movably provided at the opening end of the vehicle compartment 101. The bottom of the vehicle compartment 101 near the opening end is hinged to the vehicle body 100. A loading and unloading mechanism 300 is rotatably provided on the inner wall of the vehicle compartment 101 near the opening end. The loading and unloading mechanism 300 comprises a transport component for transporting goods and a locking component capable of fixing the position of the transport component. A cargo stacking mechanism 200 is provided near the loading and unloading mechanism 300 in the vehicle compartment 101.

[0028] When loading goods, the locking component is moved to release the position lock of the transport component, the placement angle of the transport component is adjusted, and the transport component is used to transport the goods into the carriage 101 to achieve loading of the goods. When the bottom surface of the carriage 101 is full, the goods can be stacked by the stacking mechanism 200.

[0029] By setting up the loading and unloading mechanism 300, the loading and unloading of goods is facilitated, the convenience of the unmanned transport vehicle is improved, the labor cost is reduced, and the work efficiency is improved. By setting up the cargo stacking mechanism 200, the stacking of goods is achieved, and the internal space of the carriage 101 is reasonably utilized, so that the unmanned transport vehicle can load more goods, thereby enhancing the practicality of the unmanned transport vehicle.

[0030] See also Figure 2-Figure 5 As shown, the transport assembly includes a transport belt 302 , and a movable plate 301 is symmetrically rotated along the central axis of the carriage 101 on the inner wall of the carriage 101 , and the transport belt 302 is arranged on the opposite side walls of the two movable plates 301 .

[0031] When cargo needs to be loaded, the movable plate 301 is rotated to an inclined state, and an external motor is used to drive the movable plate 301 to operate, and the cargo is placed on the movable plate 301, and the cargo is transported to the carriage 101 through the movable plate 301, thereby reducing manual handling costs and safety hazards, saving time, and improving the work efficiency of the unmanned transport vehicle in loading cargo.

[0032] See also Figure 3-Figure 5 As shown, a plurality of baffles 303 are arranged on the conveyor belt 302 .

[0033] The blocking bar 303 is provided to prevent the cargo from sliding off the movable plate 301 , thereby enhancing the reliability of the unmanned transport vehicle in loading cargo.

[0034] See also Figure 3-Figure 5As shown, the locking assembly includes a locking block 304 and a limit block 305. The limit block 305 is symmetrically rotated along the central axis of the carriage 101 and is arranged on the inner wall of the carriage 101. The side of the movable plate 301 away from the opening end of the carriage 101 abuts against the limit block 305. A locking hole 306 adapted to the locking block 304 is opened on the inner wall of the carriage 101. The locking block 304 is inserted into the locking hole 306, and the side of the movable plate 301 close to the opening end of the carriage 101 abuts against the locking block 304.

[0035] The limit block 305 can be used to limit the movable plate 301 to prevent the movable plate 301 from shaking due to the shaking of the vehicle body 100. The locking block 304 can be used to lock the position of the movable plate 301 to improve the stability of the unmanned transport vehicle.

[0036] See also Figure 3-Figure 6 As shown, the locking block 304 is provided with a movable groove 403, a connecting plate 402 is movably provided in the movable groove 403, a spring 404 is provided between the bottom of the connecting plate 402 and the inner wall of the movable groove 403, a pressing rod 401 and a locking rod 405 are fixedly provided on the top of the connecting plate 402, a through hole for the pressing rod 401 and the locking rod 405 to pass through is provided on the locking block 304, and the locking rod 405 is snapped into the locking hole 306.

[0037] When the movable plate 301 needs to be used, the pressing rod 401 is pressed to drive the connecting plate 402 to move downward, compressing the spring 404 so that the locking rod 405 shrinks into the movable groove 403, and then the locking block 304 is pulled out of the locking hole 306 to release the lock on the position of the movable plate 301. The position of the movable plate 301 can be adjusted to enhance the flexibility of the unmanned transport vehicle.

[0038] See also Figure 1-Figure 4 As shown, the cargo stacking mechanism 200 includes a conveyor belt 202, a screw rod 204 is rotatably provided at the bottom of the carriage 101, a guide rod 205 is fixedly provided at a position of the inner bottom of the carriage 101 corresponding to the screw rod 204, a moving block 206 is provided on the screw rod 204 and the guide rod 205, side plates 207 are fixedly provided on the opposite side walls of the two moving blocks 206, the conveyor belt 202 is arranged on the opposite side walls of the two side plates 207, a second motor 203 is provided on the side wall of one of the side plates 207, the working end of the second motor 203 is transmission-connected to the conveyor belt 202, a first motor 201 is provided on the top of the carriage 101, and the working end of the first motor 201 is transmission-connected to the top of the screw rod 204.

[0039] When the goods need to be stacked, the goods are placed on the conveyor belt 202, and the first motor 201 drives the screw 204 to rotate. The rotation of the screw 204 drives the moving block 206 to move upward, thereby driving the conveyor belt 202 to move upward to the height of the bottom layer of goods, and then the second motor 203 drives the conveyor belt 202 to operate, so that the goods move to the top of the bottom layer of goods, thereby realizing the stacking of goods, making more rational use of the internal space of the carriage 101, and allowing the unmanned transport vehicle to load more goods.

[0040] See also Figure 2-Figure 4 As shown, a plurality of rollers 103 are horizontally provided along the axis direction of the carriage 101 at a position of the inner wall of the carriage 101 away from the opening end.

[0041] By providing a plurality of rollers 103 , it is convenient for goods to move in the carriage 101 , which is beneficial for the unmanned transport vehicle to load goods. The goods are sequentially entered into the carriage 101 by the rolling of the rollers 103 , thereby enhancing the practicality of the unmanned transport vehicle.
