[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Example 1

[0026] like Figure 1 As shown, this embodiment provides an automatic loading and unloading mechanism for an express delivery unmanned vehicle, including an equipment bracket 1, an L-shaped guide rail 5, a connecting rod mechanism 4 and an actuator 3. The L-shaped guide rail 5 is installed on the equipment bracket 1, and a slider is provided on the L-shaped guide rail 5. The slider is connected to the shelf device 6 through the connecting rod mechanism 4. The slider is driven by the actuator 3 to move on the L-shaped guide rail 5, thereby realizing the movement of the shelf device 6 on the L-shaped guide rail 5 to realize loading and unloading of goods.

[0027] The actuator 3 provides power to drive the slider to move by connecting to the power assembly 2. The output end of the power assembly 2 is connected to one end of the actuator 3, and the other end of the actuator 3 is connected to the connecting rod mechanism 4.

[0028] The L-shaped guide rail 5 includes a first section and a second section, the first section is installed on the equipment bracket 1, and the second section is suspended below the end of the equipment bracket 1. The connection between the first section and the second section is arc-shaped. The goods are translated by moving the shelf device 6 on the first section, and the goods are moved up and down by moving the shelf device 6 on the second section. The direction of the shelf device is rotated at the connection between the first section and the second section.

[0029] When in use, the shelf device 6 moves on the L-shaped guide rail 5, realizing parallel movement in the first section and up and down movement in the second section, realizing movement in two different directions on the L-shaped guide rail 5, facilitating loading and unloading according to different position requirements. Example 2

[0030] This embodiment is based on the automatic loading and unloading mechanism for unmanned express delivery vehicles provided in Example 1, except that:

[0031] like Figure 2As shown, there are two L-shaped guide rails 5, which are respectively installed on the two side edges of the equipment bracket 1. A first slider 501 and a second slider 502 are provided on each L-shaped guide rail 5. The first slider 501 is closer to the first section of the L-shaped guide rail than the second slider 502.

[0032] The connecting rod mechanism 4 includes a first rod 401, a second rod 402, a third rod 403 and a fourth rod 404. The two ends of the first rod 401 are respectively connected to the first sliders 501 on the two L-shaped guide rails 5, and the second rod is installed on one side of the shelf device 6. The two ends of the third rod 403 are respectively hinged to the first rod 401 and the second rod 402, and the two ends of the fourth rod 404 are respectively connected to the second sliders 502 on the two L-shaped guide rails 5, and are installed at the same time on the side of the shelf device 6 where the second rod 402 is installed.

[0033] The fourth rod 404 is located on the shelf device 6 at a lower position than the second rod 402 . Two third rods 403 hinged to the first rod 401 and the second rod 402 are symmetrically provided to strengthen the connection with the shelf device 6 and improve the stability of the shelf device 6 .

[0034] The middle part of the first rod 401 is connected to one end of the actuator 3, and the other end of the actuator 3 is connected to the output end of the power assembly 2. The power assembly 2 is installed on the end of the equipment bracket 1 away from the carriage. The power assembly 2 drives the actuator 3 to pull the first sliders 501 at both ends of the first rod 401 to move on the L-shaped slide rail.

[0035] The actuator 3 drives the slider to move on the first section of the L-shaped guide rail 5. When the actuator 3 is pushed to the farthest distance, the first rod 401 is located near the curved portion of the first section of the L-shaped guide rail 5, and the fourth rod 404 is located on the second section of the L-shaped guide rail 5. The shelf device 6 is in a vertical state. When the actuator 3 is pulled to the nearest end to the power assembly 2, the first rod and the fourth rod are both on the first section of the L-shaped guide rail 5. Since the third rod 403 is hinged to the first rod 401 and the second rod 402, the shelf device 6 is in a flat state. Moreover, when the fourth rod 404 moves at the connecting curved portion of the first section and the second section of the L-shaped guide rail 5, the shelf device 6 will gradually change from a vertical state to a flat state. When the sliders at both ends of the fourth rod 404 are completely in the first section, the shelf device 6 changes to a flat state parallel to the L-shaped slide rail.

[0036] The second rod 402 and the fourth rod 404 are connected via a protrusion on the shelf device 6. The two protrusions are arranged on the same straight line at intervals, and both ends of the rod are mounted on the protrusions.

[0037] The actuator 3 can be selected from a hydraulic cylinder, an electric push rod, a screw rod or other telescopic mechanisms.

[0038] The L-shaped guide rail 5 is provided with travel switches at the initial position and the end position of the connecting rod mechanism 4 to realize the automatic stopping of the power assembly 2.

[0039] During use, when actuator 3 pushes first rod 401 away from power assembly 2, racking device 6 moves on the first section of L-shaped guide rail 5. When the sliders at both ends of fourth rod 404 reach the curved portion connecting the first and second sections, first rod 401 remains on the first section. Actuator 3 continues to push first rod 401, and racking device 6 changes direction as fourth rod 404 and second rod 402 move. When the two sliders on first rod 401 approach the curved portion, they reach the end position of L-shaped guide rail 5, placing racking device 6 at its lowest point. The limit switch is triggered, shutting off power assembly 2. When racking device 6 reaches its lowest point on L-shaped guide rail 5, cargo loading and unloading can be performed quickly and labor-savingly. Similarly, when racking device 6 moves from the second section to the first section, it first rises on the first section and turns at the curved portion. Then, it translates on the second section, returning to its initial position on L-shaped guide rail 5. This triggers the limit switch, shutting off power assembly 2, and cargo loading and unloading can begin on racking device 6.

[0040] The present application has a simple structure and is easy to use. The L-shaped guide rail 5 is used to realize the movement of goods in different directions and the rotation between different directions, thereby realizing the movement of goods in multiple directions.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
