The development of unmanned intelligent logistics distribution vehicles with self-adaptive goods limiting and dynamic buffering functions has become an important direction to solve the problem of goods safety and promote the development of intelligent logistics. The device realizes the precise fixing and impact energy absorption of goods through the innovative mechanical linkage structure and elastic buffering design, providing technical support for the safe and reliable operation of the unmanned distribution system.
[0003] The existing goods fixing technology of logistics distribution vehicles mainly relies on two types of solutions.

DETAILED DESCRIPTION
[0032] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0033] With reference to Figures 1-3 The utility model provides an embodiment: an unmanned intelligent logistics distribution car, including car body 1, car body 1 bottom is provided with electric wheel 2, car body 1 both sides are fixedly connected with hinge 3, one of hinge 3 one side is fixedly connected with car door one 4, another hinge 3 one side is fixedly connected with car door two 10, and car door two 10 and car door one 4 are connected with car body 1 through hinge 3, and car door one 4 top and car door two 10 bottom are pasted, can open and close freely according to need, ensure the safety of sealing property and goods storage, car body 1 inside is provided with limiting component, and car door one 4 one side is provided with connecting component,
[0034] The limiting component includes slide column 5, the slide column 5 is slidably connected in the car body 1, and the slide column 5 one side is fixedly connected with the limiting plate 6, is used to ensure the stability of goods, and the slide column 5 outer wall is sleeved with spring one 7, and the both ends of spring one 7 are fixedly connected in the car body 1 and the limiting plate 6, and spring one 7 plays the buffering effect, when external force acts on the limiting plate 6, spring one 7 will be compressed, store energy, after the disappearance of external force, spring one 7 will quickly restore original shape, push limiting plate 6 to return to the original position, to ensure that goods is always in stable state, and the car body 1 is fixedly connected with buffer pad 8 in, and buffer pad 8 adopts high density rubber material, has good shock absorbing performance and wear resistance, can effectively disperse and slow down the impact force generated by collision, and the one side of buffer pad 8 extends outside the car body 1, when the car body 1 encounters external collision or vibration, buffer pad 8 will first contact external object, disperse and absorb impact force, effectively slow down the influence of vibration on goods.
[0035] Specifically, when using the logistics distribution vehicle, first, the door one 4 and the door two 10 are opened through the hinge 3, the hinge 3 connects the door one 4 and the door two 10 through a rotating shaft, so that they can be freely opened and closed at a certain angle. After opening the door, the staff can put the goods into the vehicle body 1, ensuring that the outer surface of the goods is tightly attached to one side of the limiting plate 6 inside the vehicle body 1. When the goods are placed, the limiting plate 6 will be displaced due to the weight and external pressure of the goods, thereby driving the slide column 5 on one side to slide inside the vehicle body 1. At the same time, the limiting plate 6 exerts pressure on the spring one 7 on one side, which will be compressed. When the spring one 7 is compressed to a certain extent, it will return to its original state, driving the limiting plate 6 to tightly adhere to the outside of the goods, thereby effectively limiting the goods. The limiting plate 6 can effectively limit the position of the goods inside the vehicle body 1, preventing the goods from shifting or tilting during transportation, ensuring the safety of the goods. During transportation, when the vehicle body 1 is subjected to external impact or collision, the buffer pad 8 outside the vehicle body 1 will first come into contact with the collision object. At the same time, the limiting plate 6 and the spring one 7 inside the vehicle body 1 will be affected by the external impact force and will shrink. At this time, the limiting plate 6 cooperates with the spring one 7 to achieve the buffering effect on the goods through the spring's rebound force, relieving the vibration caused by external forces during transportation. The rebounding ability of the spring one 7 enables the limiting plate 6 to quickly return to its original position, effectively preventing the position of the goods from changing during transportation, thereby effectively protecting the goods from damage.
[0036] With reference to Figure 1 and Figure 4 , the connecting assembly includes a fixed plate 13 and a fixed ring 14, one side of the fixed plate 13 is fixedly connected to one side of the door one 4, and the outer wall of the fixed ring 14 is fixedly connected to one side of the fixed plate 13. One side of the door two 10 is fixedly connected with a connecting frame 11, which realizes the stable connection of the door one 4 and the door two 10 through the design of the connecting frame 11. One side of the connecting frame 11 is fixedly connected with an arc-shaped block 12. A latch 15 is slidably connected inside the fixed ring 14, and the latch 15 is provided inside the connecting frame 11. The safe closure of the door body is realized through the fixation of the latch 15 and the connecting frame 11.

A limiting groove 20 is formed inside the support plate 19, and the lever 18 is slidably connected inside the limiting groove 20. The limiting groove 20 effectively controls the sliding range of the lever 18.
[0037] Specifically, when preparing to close the door one 4 and the door two 10, first, the door two 10 is flipped to the top of the vehicle body 1, then the door one 4 is flipped to the side of the vehicle body 1, at this time, the bolt 15 on one side of the door one 4 will contact the arc-shaped block 12 on one side of the door two 10, so that the bolt 15 starts to slide inside the fixed ring 14, the sliding process of the bolt 15 will cause the connecting ring 17 on the outer wall to move correspondingly, the connecting ring 17, through its connection with the spring two 16, will compress the spring two 16 under the action force, until the door one 4 and the door two 10 are completely closed tightly, at this time, the compression energy of the spring two 16 will make the connecting ring 17 restore to its original state, locking the bolt 15 in the connecting frame 11 on one side of the door two 10, thereby completing the safe locking of the door one 4 and the door two 10, when opening the door, the staff only needs to pull the pull rod 18, through the pull rod to make it slide inside the support plate 19, when the pull rod 18 slides, it drives the bolt 15 to slide out from inside the connecting frame 11, realizing the unlocking of the door and the box door, thereby completing the opening, making the operation more simple, realizing the convenient opening and closing operation.
