Description

Technical Field

[0001] The utility model relates to an auxiliary wheel for cleaning equipment. Background Art

[0002] Currently, cleaning equipment such as sweepers and floor scrubbers are typically equipped with running wheels. The running wheels are driven by a motor to rotate, thereby driving the cleaning equipment to move along a specific path so that the cleaning equipment can clean the ground. Existing running wheels generally include a hub and a tire. For example, Chinese Patent Publication No. CN218536220U discloses a wheel for floor scrubbers, which includes a hub and a tire connected to the hub. The tire also has anti-skid grooves on its outer surface. However, the anti-skid grooves on the tire extend along the circumference of the tire, resulting in poor anti-skid effect. When encountering wet and slippery ground, the friction between the tire and the ground is insufficient, resulting in poor tire grip and prone to slipping. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an auxiliary wheel for cleaning equipment, which can increase the friction between the wheel and the ground, thereby improving the grip and avoiding slipping.

[0008] Furthermore, two adjacent circles of anti-slip protrusions are staggered in the circumferential direction of the annular body.

[0009] Furthermore, in the axial direction of the annular body, a spacing groove is provided between two adjacent circles of the anti-slip protrusions.

[0010] Furthermore, the anti-slip bumps are distributed in two circles on the outer periphery of the annular body.

[0011] In order to further improve the friction between the body and the ground, the annular body is provided with a deformation structure corresponding to the anti-slip bumps;

[0012] The deformation structure is aligned with the corresponding anti-slip protrusion in the circumferential direction of the annular body;

[0013] In the radial direction of the annular body, the deformation structure is located on the inner side of the corresponding anti-slip protrusion;

[0014] The deformation structure includes two deformation holes and a support portion located between the two deformation holes and used to provide support force for the corresponding anti-slip bumps, and a portion of the deformation hole extends into the corresponding anti-slip bump.

[0015] Furthermore, the annular body is used for assembly connection with the wheel hub, and an assembly structure is provided on the inner circumference of the annular body, which protrudes radially inward and is used for mating connection with the wheel hub.

[0016] Furthermore, the left end portion of the assembly structure is provided with a plurality of left-opening slots with openings facing leftward, and the right end portion of the assembly structure is provided with a plurality of right-opening slots with openings facing rightward.

[0017] Furthermore, the left opening grooves are distributed in sequence at intervals along the circumference of the annular body, and the right opening grooves are also distributed in sequence at intervals along the circumference of the annular body.

[0018] Furthermore, the left opening groove and the right opening groove are staggered in the circumferential direction of the annular body.

[0025] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0026] like Figures 1-3 As shown, an auxiliary wheel for cleaning equipment includes an annular body 1;

[0027] The outer periphery of the annular body 1 is provided with a plurality of anti-slip bumps 2 protruding radially outward;

[0028] The anti-slip bumps 2 are distributed in at least two circles on the outer periphery of the annular body 1, and the plurality of anti-slip bumps 2 in each circle are sequentially spaced along the circumference of the annular body 1;

[0029] A plurality of anti-skid bumps 3 are provided on the top of the anti-skid bump 2; specifically, by arranging the anti-skid bump 2 on the annular body 1 and arranging the anti-skid bump 3 on the top of the anti-skid bump 2, the anti-skid bump 3 on the anti-skid bump 2 is made to contact the ground, which can increase the friction coefficient between the tire and the ground, thereby improving the friction and grip between the tire and the ground, and avoiding the occurrence of slipping.

[0030] like Figures 1-3 As shown, the two adjacent circles of anti-slip protrusions 2 are staggered in the circumferential direction of the annular body 1, and a spacing groove 4 is provided between the two adjacent circles of anti-slip protrusions 2 in the axial direction of the annular body 1; the width of the spacing groove 4 is between 0.5 and 1 mm.

[0031] In this embodiment, the anti-slip bumps 2 are distributed in two circles on the outer periphery of the annular body 1 .

[0032] like Figure 1 、 2 As shown, the annular body 1 is provided with a deformation structure corresponding to the anti-slip bumps 2 one by one;

[0033] The deformation structure is aligned with the corresponding anti-slip protrusion 2 in the circumferential direction of the annular body 1;

[0034] In the radial direction of the annular body 1, the deformation structure is located on the inner side of the corresponding anti-slip protrusion 2;

[0035] The deformable structure includes two deformable holes 5 and a support portion 6 located between the two deformable holes 5 and configured to provide support for the corresponding anti-slip bump 2. A portion of the deformable hole 5 extends into the corresponding anti-slip bump 2. Specifically, because the deformable holes 5 are provided on the inner side of the anti-slip bump 2, the support strength at the deformable hole 5 is relatively weak and therefore more susceptible to deformation. Therefore, when the anti-slip bump 2 contacts the ground, it can deform to a certain extent through the deformable hole 5, thereby increasing the contact area between the anti-slip bump 3 on the top of the anti-slip bump 2 and the ground, further improving friction and grip. Furthermore, the deformable hole 5 can absorb some vibration, ensuring a smoother ride. More specifically, the support portion 6 can provide a certain amount of support for the corresponding anti-slip bump 2, thereby preventing the anti-slip bump 2 from deforming too much and affecting normal driving.

[0036] like Figure 1 、 2 As shown, the annular body 1 is used for assembly connection with the wheel hub, and an assembly structure 7 is provided on the inner periphery of the annular body 1, which protrudes radially inward and is used for mating connection with the wheel hub.

[0037] like Figure 1 、 2 As shown, the left end portion of the assembly structure 7 is provided with a plurality of left-opening grooves 8 with openings facing left, and the right end portion of the assembly structure 7 is provided with a plurality of right-opening grooves 9 with openings facing right; specifically, the left-opening grooves 8 and the right-opening grooves 9 are both used to be connected with the corresponding clips on the wheel hub.

[0038] like Figure 1 、 2 As shown, the left opening grooves 8 are sequentially spaced apart along the circumference of the annular body 1 , and the right opening grooves 9 are also sequentially spaced apart along the circumference of the annular body 1 ;

[0039] The left opening groove 8 and the right opening groove 9 are staggered in the circumferential direction of the annular body 1;

[0040] A left block 10 is provided between adjacent left opening slots 8, and a left clamping hole 11 with an opening facing left is provided in the left block 10;

[0041] A right block 12 is provided between adjacent right opening slots 9 , and a right clamping hole 13 with its opening facing right is provided in the right block 12 ; specifically, the left clamping hole 11 and the right clamping hole 13 are both used to cooperate with corresponding inserts on the wheel hub.

[0042] To sum up, by arranging the anti-skid bump 2 on the annular body 1 and arranging the anti-skid point 3 on the top of the anti-skid bump 2, the anti-skid point 3 on the anti-skid bump 2 is made to contact the ground, which can increase the friction coefficient between the tire and the ground, thereby improving the friction and grip between the tire and the ground, and avoiding the occurrence of slipping.

[0043] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
