[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Wheeled mobile devices (e.g., lawn mowers, etc.) have rotating wheels coupled to a drive mechanism. When obstacles such as mud, sloping fields or sand exist, the rotating wheel often has a slipping phenomenon, so that the mower is difficult to move. At present, tires of rotating wheels are generally made of rubber materials and have teeth, the rotating wheels increase the ground holding force through the teeth on the tires, and the tires made of the rubber materials improve the shock absorption performance. However, in practical application, the rotating wheel is not ideal in damping effect, and the problem of damping failure is easy to occur along with the aging of rubber.

Therefore, the embodiment of the utility model provides a rotate wheel and wheeled equipment of traveling, should rotate wheel and wheeled equipment of traveling not only can improve the shock attenuation effect, can effectively avoid the problem of shock attenuation inefficacy moreover.

Specifically, as shown in fig. 1, the wheeled travel device of the present application is a lawn mower. The lawn mower includes an apparatus body 100 and rotary wheels 200, and the rotary wheels 200 are provided on opposite sides of the apparatus body 100.

It should be noted that the wheeled travel apparatus of the present application is not limited to a lawnmower, and a lawnmower is merely an example of the wheeled travel apparatus of the present application.

Referring to fig. 2 to 7, the rotating wheel 200 includes a hub 10 and a tire 30, and the tire 30 is sleeved on the hub 10.

As shown in fig. 2, the hub 10 includes an inner rim 11, an outer rim 13 and a plurality of reinforcing ribs 15, the outer rim 13 is disposed around the inner rim 11, and the inner rim 11 and the outer rim 13 are connected through the plurality of reinforcing ribs 15, so that the inner rim 11 supports the outer rim 13 through the plurality of reinforcing ribs 15, the plurality of reinforcing ribs 15 are arranged at intervals along the circumferential direction of the outer rim 13, the reinforcing ribs 15 extend along the axial direction of the outer rim 13, and a deformation space 17 for allowing the outer rim 13 to elastically deform is formed between two adjacent reinforcing ribs 15.

Because the hub 10 comprises the inner ring 11 and the outer ring 13, the inner ring 11 and the outer ring 13 are connected through the plurality of reinforcing ribs 15, and a deformation space 17 for the outer ring 13 to elastically deform is formed between two adjacent reinforcing ribs 15, when the tire 30 is impacted, the tire can not only elastically buffer and absorb the impact action through the self elastic buffer and the impact absorption, but also elastically deform into the deformation space 17 through the outer ring 13 to buffer and absorb the impact action, thereby improving the damping effect; meanwhile, when the tire 30 is aged and loses the damping effect, the impact can be buffered and absorbed through the elastic deformation of the outer wheel ring 13, so that the rotating wheel has better damping failure resistance in the long-term use process. .

The deformation space 17 for elastically deforming the outer ring 13 is formed between the two adjacent beads 15: because the supporting effect of strengthening rib 15, outer rim 13 can be divided into a plurality of deformation regions 130 that lie in between two adjacent strengthening ribs 15, has the interval between deformation region 130 and the interior rim 11, when external impact transmitted deformation region 130 through tire 30, deformation region 130 can produce elastic deformation, and this elastic deformation can make deformation region 130 move to the position that is close to interior rim 11.

Wherein, the inner ring 11 and the reinforcing ribs 15 are made of rigid materials, and the rigid materials can be aluminum alloy materials, stainless steel materials and the like; outer wheel rim 13 adopts elastically deformable's material to make, and elastically deformable's material can be elastic steel material, rubber materials etc. when elastically deformable's material was elastic steel material, in order to guarantee that deformation region 130 has suitable elastic deformation performance, can run through on deformation region 130 and set up the through-hole.

In the present embodiment, the inner ring 11 and the outer ring 13 are coaxially disposed. So configured, the same or approximately the same damping effect can be provided to the rotating wheel 200 at different positions in its circumferential direction.

As shown in the figure, a plurality of anti-slip ribs 31 are formed on the inner tread 30A of the tire 30, the plurality of anti-slip ribs 31 are distributed at intervals along the circumferential direction of the tire 30, the anti-slip ribs 31 extend along the axial direction of the tire 30, a plurality of grooves 131 are formed on the outer tread 13A of the outer rim 13, each anti-slip rib 31 corresponds to each groove 131 one by one, and at least part of the anti-slip rib 31 is accommodated in the corresponding groove 131. Relative slip between the tire 30 and the hub 10 is prevented by the interfitting of the ribs 31 and grooves 131.

Alternatively, the portion of the rib 31 received in the corresponding groove 131 abuts against the groove surface of the groove 131. The non-skid property between the tire 30 and the hub 10 can be enhanced by the static friction force between the beads 31 and the groove surfaces of the grooves 131 by the abutment of the beads 31 with the groove surfaces of the grooves 131.

Alternatively, the inner tread 30A of the tire 30 or/and the outer tread 13A of the outer rim 13 may be provided with a concave-convex structure in order to enhance the static friction between the inner tread 30A of the tire 30 and the outer tread 13A of the outer rim 13. Wherein, the concave-convex structure can be a combination of skid-proof patterns, bulges and depressions.

Alternatively, in order to enhance the static friction between the rib 31 and the groove surface of the groove 131, a concave-convex structure may be provided on the surface of the rib 31 or/and the groove surface of the groove 131.

As shown, the grooves 131 are formed by recessing the outer wheel surface 13A of the outer wheel rim 13 toward the inner wheel rim 11, the ribs 15 and the grooves 131 are arranged in a one-to-one correspondence, and each rib 15 is connected to the inner wheel surface 13B of the outer wheel rim 13 at a position corresponding to each groove 131. Under the condition that the elastic modulus of the material of the outer rim 13 is not changed, the grooves 131 are formed by the outer rim surface 13A of the outer rim 13 being recessed towards the inner rim 11, the reinforcing ribs 15 and the grooves 131 are arranged in a one-to-one correspondence manner, and each reinforcing rib 15 is respectively connected to the position of the inner rim surface 13B of the outer rim 13 corresponding to each groove 131, so that the elasticity of the outer rim 13 can be improved, and the damping effect can be further improved. It will be appreciated that in other embodiments, the groove 131 may be formed by cutting a portion of the material from the outer wheel face 13A of the outer wheel rim 13, but this would tend to reduce the strength of the outer wheel rim 13 in the groove 131 and thus reduce the threshold force at which the outer wheel rim 13 breaks when impacted.

In the present embodiment, the inner ring 11, the outer ring 13, and the plurality of ribs 15 are integrally molded. With this arrangement, the number of parts of the rotary wheel 200 can be reduced, so that the assembly process of the rotary wheel 200 can be simplified.

For example, when the inner ring 11 and the reinforcing ribs 15 are made of stainless steel and the outer ring 13 is made of elastic steel (i.e. the inner ring 11, the outer ring 13 and the reinforcing ribs 15 are made of the same material, and the three are different only in elasticity of the finished product), the inner ring 11, the outer ring 13 and the reinforcing ribs 15 can be formed in one step by an integral forming process; when the inner rim 11 and the reinforcing ribs 15 are made of rigid materials and the outer rim 13 is made of rubber materials, the inner rim 11 and the reinforcing ribs 15 can be formed in one step by an integral forming process, and then the assembly formed by the inner rim 11 and the reinforcing ribs 15 can be formed in one step with the outer rim 13 by an injection molding process.

It should be noted that, when the inner ring 11 and the reinforcing ribs 15 are made of the same rigid material, the outer ring 13 is made of the rubber material, and the inner ring 11, the outer ring 13 and the plurality of reinforcing ribs 15 are integrally formed, in order to ensure the connection strength between the outer ring 13 and the reinforcing ribs 15, a reinforcing structure embedded in the outer ring 13 may be provided on the reinforcing ribs 15. For example, the reinforcing structure may be a T-shaped structure or a Y-shaped structure, etc.

It will be appreciated that the inner rim 11, outer rim 13 and plurality of ribs 15 are not limited to being formed as a single integral part. For example, the inner ring 11, the outer ring 13, and the plurality of ribs 15 may be provided as separate members; or, the inner ring 11 and the plurality of reinforcing ribs 15 are integrally formed; or, the outer wheel ring 13 and the plurality of reinforcing ribs 15 are integrally formed; of course, in order to facilitate the connection between the separate bodies and ensure the connection strength between the separate bodies, it is preferable that the inner ring 11, the outer ring 13 and the reinforcing ribs 15 are made of steel materials.

The tread 30B of the tire 30 is formed with a plurality of teeth 33 arranged in the circumferential direction of the tire 30, and the plurality of teeth 33 are staggered in the axial direction of the tire 30. This can improve the grip of the rotary wheel 200, and thus can improve the passing performance of the rotary wheel 200 through a sand-stone ground, a mud ground, or a multi-obstacle ground.

As shown, the tread 30B of the tire 30 includes a first surface 35 and a second surface 37, the first surface 35 and the second surface 37 are distributed along the axial direction of the tire 30, and the first surface 35 and the second surface 37 form a height difference in the radial direction of the tire 30 (i.e., the first surface 35 and the second surface 37 have different diameters), the plurality of teeth 33 includes a plurality of first teeth 33A and a plurality of second teeth 33B, the plurality of first teeth 33A are arranged along the circumferential direction of the first surface 35, the plurality of second teeth 33B are arranged along the circumferential direction of the second surface 37, and the plurality of first teeth 33A and the plurality of second teeth 33B are arranged alternately along the axial direction of the tire 30.

It is understood that the tread 30B of the tire 30 is not limited to including the first surface 35 and the second surface 37. For example, in other embodiments, the outer tread 30B of the tire 30 may further include a third surface, the first surface 35, the second surface 37 and the third surface are distributed along the axial direction of the tire 30, and the first surface 35, the second surface 37 and the third surface sequentially form a height difference along the radial direction of the tire 30 (i.e., the first surface 35, the second surface 37 and the third surface have different diameters), and accordingly, the plurality of teeth 33 further includes a plurality of third teeth, the plurality of third teeth are arranged along the circumferential direction of the third surface, and at least two of the plurality of first teeth 33A, the plurality of second teeth 33B and the plurality of third teeth are arranged in a staggered manner along the axial direction of the tire 30.

The inner tread 30A of the tire 30 is formed with a first flange 38 and a second flange 39, the first flange 38 and the second flange 39 are provided at intervals in the circumferential direction of the tire 30, and the hub 10 is interposed between the first flange 38 and the second flange 39. By providing the first and

second flanges

38, 39 such that the hub 10 is interposed between the first and

second flanges

The provision of the first and

second flaps

38, 39 in this manner facilitates the formation of the tyre 30.

The rotator wheel further includes a hub motor 50, and the hub motor 50 is disposed in the inner race 11 and drives the rotator wheel 200 to rotate.

As shown in fig. 4, the in-wheel motor 50 includes a motor 51 and a connecting shaft 53, the motor 51 is disposed in the inner race 11, and the connecting shaft 53 connects the motor 51 and the apparatus main body 100.

It should be noted that when the rotary wheel 200 includes the in-wheel motor 50, the rotary wheel 200 serves as a driving wheel of the wheel type traveling apparatus, and when the rotary wheel 200 does not include the in-wheel motor 50, the rotary wheel 200 may serve as a driven wheel of the wheel type traveling apparatus.
