Description

Technical Field

[0001] The utility model relates to the technical field of intelligent vehicles, and in particular to a lifting mechanism for an unmanned vehicle. Background Art

[0002] Cage carts are unit-sized mobile containerized equipment equipped with several casters for transporting and storing goods. They are a common cargo carrier in logistics, transit, and sorting. They enable rapid unloading, online sorting, and loading of goods, improving express delivery efficiency. During the logistics and transportation process, cage carts not only ensure the safety of materials, but also prevent clutter in sorted goods, saving time and effort during subsequent loading and unloading.

[0003] At present, cage trucks and logistics vehicles are independent of each other and have no connection. After the goods are loaded into the cage truck, they need to be moved to the logistics vehicle by manual labor or forklifts. After arriving at the destination or transfer point, the cage truck needs to be unloaded. Since the fully loaded cage truck is heavy (can reach about 400 kg), the handling efficiency is low, which extends the transportation time of express delivery and poses certain safety hazards.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 3 As shown, the lifting mechanism for the unmanned vehicle of this embodiment includes a load-bearing platform 2, a lifting bracket 31, a lifting guide rail 32 provided on the unmanned vehicle 1, and a lifting drive 33 for driving the lifting bracket 31 relative to the lifting guide rail 32. The lifting bracket 31 is connected to the load-bearing platform 2, and the lifting guide rails 32 are arranged on opposite sides of the lifting bracket 31 and are slidably connected to the lifting bracket 31. The load-bearing platform 2 is used to support and limit the cage car 4. It is an existing component and will not be described in detail here.

[0027] The lifting mechanism of the unmanned vehicle of this embodiment, when it is necessary to load goods, the lifting drive member 33 drives the lifting bracket 31 to descend, and the carrying platform 2 descends with the lifting bracket 31. After descending to a lower height, it is convenient to transport the cage car 4, containers, sales cabinets, etc. to the carrying platform 2, and then the lifting drive member 33 drives the lifting bracket 31 and the carrying platform 2 to rise; after the unmanned vehicle 1 travels to the destination, the carrying platform 2 is lowered to a lower height again, which is convenient for unloading the cage car 4, containers, sales cabinets, etc. It is easy to use and is conducive to improving loading and unloading efficiency. The lifting guide rails 32 on both sides of the lifting bracket 31 can provide a guiding effect for the lifting movement of the lifting bracket 31, making the lifting movement more stable and smooth to avoid deviation.

[0028] Furthermore, in this embodiment, the lifting guide rail 32 is provided with a guide groove 321, and the lifting bracket 31 is provided with a roller, which is disposed in the guide groove 321. The provision of the roller can reduce frictional resistance during the lifting process of the lifting bracket 31, and the guide groove 321 can provide guidance for the roller to prevent deviation, resulting in a simple and reliable structure.

[0029] Furthermore, in this embodiment, limiters 322 are provided at both the upper and lower ends of the guide slot 321. The limiters 322 limit the maximum travel of the roller, preventing the roller from falling out of the guide slot 321. In particular, the limiter 322 at the lower end prevents the lifting bracket 31 from falling, thereby improving reliability.

[0030] Furthermore, in this embodiment, the roller includes a first roller 311 and a second roller 312, and the axes of the first roller 311 and the second roller 312 are perpendicular. Figure 2 The first roller 311 cooperates with the two side walls of the guide groove 321, and the second roller 311 cooperates with the bottom wall of the guide groove 321 to avoid deviation along the x-axis and y-axis directions during the lifting process, further improving reliability.

[0031] As a preferred embodiment, two first rollers 311 and two second rollers 312 are provided, which is beneficial to further strengthen the guiding effect and prevent deviation.

[0032] Furthermore, in this embodiment, a connecting frame 34 is provided between the lifting guide rails 32 on both sides, and the middle portion of the connecting frame 34 is connected to the lifting drive member 33. The connecting frame 34 can connect the lifting guide rails 32 on both sides into one body. At the same time, the middle portion of the connecting frame 34 serves as the connection point for the lifting drive member 33, which facilitates the uniform transmission of the force applied by the lifting drive member 33 to the lifting guide rails 32 on both sides, thereby improving symmetry and balance.

[0033] Furthermore, in this embodiment, the connecting frame 34 includes two connecting beams 341, and the lifting bracket 31 is located between the two connecting beams 341. The two connecting beams 341 can provide a limit for the lifting bracket 31 to prevent the lifting bracket 31 from moving along the Figure 1 The x-axis direction is offset, and the structure is simple and reliable, so that the lifting bracket 31 will not shake.

[0034] As a preferred embodiment, the lower end of the lifting bracket 31 is connected to the carrying platform 2, and the middle part of the upper end of the lifting bracket 31 is connected to the lifting drive member 33, which has good symmetry and balance.

[0035] In a preferred embodiment, the lift drive 33 is an electric push rod. The upper end of the electric push rod is hinged to the middle of the upper end of the lift bracket 31, and the lower end of the electric push rod is hinged to the middle of the connecting frame 34. The lift bracket 31 can be raised and lowered by extending and retracting the electric push rod. The hinged structure at the upper and lower ends of the electric push rod helps to prevent jamming. Of course, in other embodiments, the lift drive 33 can also be a pneumatic cylinder, an oil cylinder, etc., which will not be repeated here.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
