[0002] Automated Guided Vehicle (AGV) is abbreviated as AGV. It uses a single or multiple drive wheels to provide power to enable the AGV to move forward, backward, and horizontally. The existing AGV drive wheel generally integrates the drive motor and the reducer into one, referred to as the AGV integrated drive wheel. In order to adapt to various ground conditions, the hub surface of the AGV drive wheel that contacts the ground is designed with a wide variety of surface texture solutions to meet the stable operation requirements of clean ground, oily ground, water-stained ground, waxed ground and other environments. At the same time, the AGV integrated drive wheel generates a lot of heat during the working process. In order to make the AGV integrated drive wheel dissipate heat well, thermal grease is usually applied to its structural mounting surface, so that the AGV integrated drive wheel has a better heat dissipation effect and reduces the internal temperature of the AGV integrated drive wheel. Therefore, the existing AGV integrated drive wheel needs surface texture treatment, resulting in a wide variety of materials and inconvenient management. At the same time, thermal grease needs to be applied to the mounting surface, making the process cumbersome and the assembly workload relatively large. Therefore, a non-slip drive wheel mechanism and an automatic navigation device are provided to solve the above problems. Summary of the invention

[0003] One of the purposes of the utility model is to provide an anti-skid driving wheel mechanism and an automatic navigation device, so as to solve the problem of the existing AGV integrated driving wheel structure and complex assembly.

[0005] The utility model discloses an anti-skid driving wheel mechanism comprising a driving motor; a reducer, which is drivingly connected to the driving motor; a wheel hub, which is made of elastic material, and the wheel hub is sleeved on a rotating disk of the reducer;

[0006] Among them, a plurality of grooves are arranged on the surface of the wheel hub that contacts the ground, and the grooves are squeezed and deformed by the ground so that the grooves can be adsorbed to the ground to prevent slipping; a plurality of fan blades are arranged on the side of the wheel hub opposite to the driving motor, and the plurality of fan blades rotate with the rotation of the wheel hub.

[0007] In one embodiment, at least one fixing ear is disposed on the outer side of the driving motor, and the anti-skid driving wheel mechanism is fixed on the AGV body through the at least one fixing ear.

[0010] In one embodiment, the reduction gear structure is a single-stage reduction gear structure or a multi-stage reduction gear structure.

[0011] In one embodiment, the wheel hub is made of polyurethane.

[0016] Compared with the prior art, the anti-skid driving wheel mechanism and the automatic navigation device of the utility model have the following beneficial effects:

[0017] The utility model discloses an anti-skid driving wheel mechanism and automatic navigation device. By arranging a plurality of grooves on the wheel hub, when the grooves come into contact with the ground, the grooves are squeezed and deformed by the ground, so that the grooves adsorb the ground to prevent skidding, thereby enhancing the anti-skid function of the driving wheel mechanism to a certain extent.

[0027] See also Figure 1-Figure 3 As shown, specifically, the material of the wheel hub 13 is polyurethane, and a plurality of grooves 131 are evenly arranged on its surface. When the corresponding plurality of grooves 131 on the wheel hub 13 begin to contact the ground, the plurality of grooves 131 are squeezed and deformed by the ground, and part or all of the air inside is removed; when the corresponding plurality of grooves 131 on the wheel hub 13 are all in contact with the ground, the inner cavity of the plurality of grooves 131 forms a certain vacuum state, firmly adsorbing the ground of the corresponding vacuum area, thereby achieving an anti-skid effect; especially for the condition that there is oil or water on the ground, the sealing property of the grooves 131 will be more superior, and the anti-skid effect will be more ideal.
