[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] The following is for reference. Figures 1 to 5 The wheel module of this application is described in detail.

[0032] refer to Figures 1 to 3According to an embodiment of the present invention, a wheel module includes a wheel 100, a tire 200, and an air valve 300. The wheel 100 includes a hub 110, a rim 120, and a first spoke 130. A receiving groove 121 is formed on the end face of the rim 120. The hub 110 and the first spoke 130 are both disposed within the receiving groove 121. Two first spokes 130 are provided, and each first spoke 130 is connected to the hub 110 and the sidewall of the receiving groove 121, respectively. The sidewall of the receiving groove 121 is provided with two protrusions 122. The first spokes 130 and the protrusions 122 are alternately distributed along the circumference of the wheel 100, and the interval between any adjacent first spokes 130 and protrusions 122 is the same. At least one protrusion 122 has an inflation hole 122a at one end facing the opening of the receiving groove 121. The tire 200 is fitted on the rim 120, and an inflation cavity 201 is defined between the outer peripheral surface of the tire 200 and the rim 120. The inflation cavity 201 communicates with the inflation hole 122a. The air valve 300 is provided in the inflation hole 122a and is used to communicate with the inflation device.

[0033] It is understood that when the wheel module of this application is used, the operator can connect the inflation device to the air valve 300, so that the inflation device can inflate the inflation chamber 201 through the air valve 300. Under the action of the air pressure in the inflation chamber 201, the tire 200 can inflate. Therefore, when the wheel module of this application rolls on the road surface, under the action of the inflation chamber 201, the tire 200 can locally dent and return to its original position to adapt to the uneven road surface, thereby reducing the bumps generated by the wheel module during the rolling process on the road surface.

[0034] Understandably, the first spoke 130 is connected to the hub 110 and the sidewall of the receiving groove 121 respectively, so that the first spoke 130 can support the sidewall of the receiving groove 121 to enhance the strength of the rim 120. The first spoke 130 and the protrusion 122 are distributed alternately along the circumference of the wheel 100, and the interval between any adjacent first spoke 130 and protrusion 122 is the same, which makes the force on the sidewall of the receiving groove 121 more uniform, the probability of the outer circumferential surface of the rim 120 is smaller, the stability of the wheel module during rolling is improved, and the bumps generated by the wheel module during rolling are further reduced.

[0035] Understandably, since the inflation hole 122a is located at the end of the protrusion 122 facing the opening of the receiving groove 121, the inflation device can connect with the air valve 300 in the inflation hole 122a along the depth direction of the receiving groove 121, and the inflation device experiences less interference during the connection with the air valve 300.

[0036] It is understandable that, since the protrusion 122 needs to be provided with an air inlet 122a, and the protrusion 122 has a large circumferential dimension in the wheel 100, by alternately setting the first spoke 130 and the protrusion 122, on the one hand, the first spoke 130 and the protrusion 122 can work together to counterweight the entire wheel 100; on the other hand, the first spoke 130 has a small circumferential dimension in the wheel 100, so that there is enough clearance space in the receiving groove 121, which facilitates the manufacturing of the wheel 100.

[0037] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 The wheel 100 also includes a second spoke 140 disposed in the receiving groove 121. The second spoke 140 is connected to the hub 110 and the groove sidewall of the receiving groove 121 respectively. A second spoke 140 is provided between any adjacent first spoke 130 and protrusion 122. Along the circumference of the wheel 100, the interval between any two adjacent second spokes 140 is the same.

[0038] Understandably, the second spoke 140 serves two purposes: firstly, it makes the weight distribution of the entire wheel 100 more even; secondly, the second spoke 140 can internally support the sidewall of the groove 121, thereby enhancing the strength of the entire rim 120.

[0039] In some embodiments of this utility model, the hub 110, the rim 120, the first spoke 130, and the second spoke 140 are integrally formed.

[0040] Understandably, the hub 110, rim 120, first spoke 130 and second spoke 140 can be manufactured as a single piece using injection molding, making the manufacturing of the entire wheel 100 easier.

[0041] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The outer circumferential surface of the rim 120 is provided with an annular first groove 123 and a second groove 124. The first groove 123 and the second groove 124 are distributed along the axial direction of the wheel 100, and the opposite ends of the tire 200 are respectively engaged in the first groove 123 and the second groove 124.

[0042] Understandably, when installing the tire 200 on the rim 120, the worker can insert the opposite ends of the tire 200 into the first slot 123 and the second slot 124 respectively, thus achieving the installation of the tire 200 on the rim 120; when it is necessary to remove the tire 200 from the rim 120, the worker can remove the opposite ends of the tire 200 from the first slot 123 and the second slot 124 respectively, thus achieving the removal of the tire 200 from the rim 120. The design of the first slot 123 and the second slot 124 makes the installation and removal of the tire 200 on the rim 120 more convenient.

[0043] It should be noted that, since the inflation chamber 201 is filled with high-pressure gas, under the action of the gas in the inflation chamber 201, if the two opposite ends of the tire 200 are only engaged in the first slot 123 and the second slot 124 respectively, the two opposite ends of the tire 200 are likely to fall off from the first slot 123 and the second slot 124 respectively.

[0044] In view of the above problems, in a further embodiment of the present invention, glue is filled between the tire 200 and the groove wall of the first groove 123; glue is filled between the tire 200 and the groove wall of the second groove 124.

[0045] It is understandable that by filling the groove walls of the tire 200 and the first groove 123 with glue, the connection of the tire 200 in the first groove 123 can be made more secure; by filling the groove walls of the tire 200 and the second groove 124 with glue, the connection of the tire 200 in the second groove 124 can be made more secure.

[0046] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 One end of the rim 120 facing away from the receiving groove 121 is used to connect with the vehicle body; the first slot 123 is located on the side of the second slot 124 facing away from the opening of the receiving groove 121. The first slot 123 has a first groove edge 123a and a second groove edge 123b, with the first groove edge 123a located on the side of the second groove edge 123b facing away from the opening of the receiving groove 121. The second slot 124 has a third groove edge 124a and a fourth groove edge 124b, with the third groove edge 124a located on the side of the fourth groove edge 124b facing away from the opening of the receiving groove 121. The radii of the first groove edge 123a, the second groove edge 123b, the third groove edge 124a, and the fourth groove edge 124b gradually increase.

[0047] It is understandable that, since the radii of the first groove edge 123a, the second groove edge 123b, the third groove edge 124a, and the fourth groove edge 124b are gradually increased, when the wheel module of this application is applied to the model car, the end of the wheel rim 120 that is away from the receiving groove 121 is connected to the car body. During the rolling process of the wheel module, the wheel module can move closer to the car body to reduce the probability of the wheel module falling off the car body.

[0048] In some embodiments of this utility model, reference is made to Figure 5 The first slot 123 has a first slot wall 123c and a second slot wall 123d. The first slot wall 123c is connected to the first slot edge 123a, and the second slot wall 123d is connected to the second slot edge 123b. Along the direction close to the opening of the first slot 123, the first slot wall 123c is gradually moved away from the second slot wall 123d.

[0049] It is understandable that, along the direction close to the opening of the first slot 123, as the first slot wall 123c is gradually moved away from the second slot wall 123d, the tire 200 can expand along the axial direction of the wheel 100 to increase the contact area between the tire 200 and the ground, thereby making the movement of the wheel module more stable as the wheel module rolls along the ground.

[0050] It is understandable that the high-pressure gas in the inflation chamber 201 will cause the tire 200 to expand. By setting the first groove wall 123c in an inclined form, the first groove wall 123c can be better adapted to the expanded tire 200.

[0051] In some embodiments of this utility model, reference is made to Figure 5 The second slot 124 has a third slot wall 124c and a fourth slot wall 124d. The third slot wall 124c is connected to the third slot edge 124a, and the fourth slot wall 124d is connected to the fourth slot edge 124b. Along the direction close to the opening of the second slot 124, the fourth slot wall 124d is gradually moved away from the third slot wall 124c.

[0052] It is understandable that, along the direction close to the opening of the second slot 124, as the fourth slot wall 124d is gradually moved away from the third slot wall 124c, the tire 200 can expand along the axial direction of the wheel 100 to increase the contact area between the tire 200 and the ground, thereby making the movement of the wheel module more stable as the wheel module rolls along the ground.

[0053] It is understandable that the high-pressure gas in the inflation chamber 201 will cause the tire 200 to expand. By setting the fourth groove wall 124d in an inclined form, the fourth groove wall 124d can be better adapted to the expanded tire 200.

[0054] In some embodiments of this utility model, reference is made to Figure 4 The rim 120 has a connecting hole 125 at one end away from the receiving groove 121. The connecting hole 125 is used to pass through the axle and extends into the hub 110.

[0055] It is understood that by extending the connecting hole 125 into the hub 110, the overall depth of the connecting hole 125 can be increased. After the wheel module of this application is applied to the model car, the axle on the car body can be inserted into the connecting hole 125 to realize the connection between the car body and the wheel module.

[0056] The model car provided according to the second aspect of the present invention includes the wheel module provided in the first aspect of the present invention.
