Preferably, the diameters of the universal wheel, the driving wheel and the forward-tilting prevention wheel have the following size ratios: 45-55: 160-175: 20-30.

Preferably, the chassis body comprises a plurality of layers of panels fixedly connected by panel connecting frames; the panel connecting frame is arranged between the panels in a tower shape.

Preferably, the front tilt prevention wheel is provided in front of a lower portion of the multi-layer panel.

Preferably, the universal wheel is fixedly connected with the panel through a universal wheel fixing frame.

Preferably, the driving wheel is fixedly connected with the panel through a driving wheel mounting frame.

Preferably, the anti-forward-tilting wheel is fixedly connected with the panel through an anti-forward-tilting wheel fixing frame.

Preferably, the driving mechanism comprises a motor corresponding to the driving wheel and a power supply of a power supply storage battery of the motor.

Compared with the prior art, the utility model discloses a main beneficial technological effect lies in:

the balance weight of the chassis and the small four-wheel structure of the chassis are reasonably arranged, so that the unmanned distribution vehicle is simple to control, good in stability and not easy to overturn; the obstacle-crossing and climbing capabilities are strong, and the trafficability is good; the method can adapt to more complex and changeable terrains, and the application scene is wider.

Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.

The components and structures or unit modules referred to in the following examples are all conventional commercially available products unless otherwise specified.

Example 1: unmanned distribution vehicle walking chassis

Referring to fig. 1, 2 and 3, the walking chassis of the unmanned distribution vehicle is arranged at the bottom of the unmanned distribution vehicle and comprises four layers of panels 1 and a plurality of panel connecting frames 2 for connecting the panels 1 layer by layer, wherein the panel connecting frames 2 are arranged in a tower shape among the panels 1; the universal wheel 3 is arranged behind the chassis body at the bottom of the lowest layer panel 1 in the forward walking direction, the diameter of the universal wheel is 50cm, the driving wheels 4 are respectively arranged in parallel with two sides of the bottom of the chassis body of the unmanned distribution vehicle, the diameter of the driving wheels 4 is 169cm, the front of the chassis body in the forward walking direction is provided with the forward-leaning prevention wheel 5, the diameter of the forward-leaning prevention wheel is 25 cm, and the height of the forward-leaning prevention wheel 5 is higher than a plane formed by the contact points of the two driving wheels 4 and the contact points of the universal wheel 3.

As shown in fig. 4, the universal wheel 3 is fixedly connected with the lowest panel 1 through a universal wheel fixing frame 31, and provides support for the panel 1 of the unmanned distribution vehicle, adjusts the moving direction and reduces the rotating friction force when the panel is turned; the driving wheel 4 is fixedly connected with the lowest layer panel 1 through a driving wheel mounting frame 41 and provides moving power for the unmanned distribution vehicle; the anti-forward-leaning wheel 5 is fixedly connected with the lowest layer panel 1 through an anti-forward-leaning wheel fixing frame 51 and is used for preventing the lowest layer panel 1 from contacting the ground firstly when the lowest layer panel 1 tilts forward instantly after going downhill and crossing obstacles, ensuring that the unmanned vehicle can go forward smoothly, protecting the panel 1, the shell and the like of the unmanned vehicle from being collided with the ground and avoiding damage.
