[0033] Please refer to Figures 1 to 2 , Figure 1 is an exploded structural schematic view of an embodiment of the wheel assembly provided by the present application; Figure 2 is a cross-sectional view of an embodiment of the wheel assembly provided by the present application.

[0034] In one aspect of the present application, a wheel assembly 100 is provided. The wheel assembly 100 comprises a rim 10. The rim 10 comprises a rim body 11 and two mounting portions 12. The two mounting portions 12 are oppositely arranged on both sides of the rim body 11 along the axial direction of the rim body 11 and are arranged around the circumference of the rim body 11. The two mounting portions 12 are used to mount a tire 30.

[0035] The wheel rim 10 is a component for mounting and supporting the tire 30, and the wheel rim 10 can absorb and dissipate the heat of the tire 30, reducing the influence of temperature on the tire 30. The mounting portion 12 can extend relative to the wheel rim body 11 in a direction away from the axis of the wheel rim body 11, which can increase the contact area of the mounting portion 12 with the tire 30, not only enabling the tire 30 to stably cooperate with the mounting portion 12, thereby enhancing the connection strength between the tire 30 and the wheel rim 10, but also enabling the tire 30 to evenly disperse pressure to the wheel rim 10 through the mounting portion 12 during the driving of the vehicle, thereby reducing stress concentration and the risk of tire 30 wear caused by uneven stress distribution.

[0036] Please refer to Figure 3 , Figure 3 is a structural schematic diagram of an embodiment of the annular noise reduction assembly of the wheel assembly provided by the present application. The wheel assembly 100 further comprises an annular noise reduction assembly 20. The annular noise reduction assembly 20 is sleeved on the outer surface of the wheel rim body 11 and is in interference connection with the wheel rim body 11.

[0037] Among them, the wheel rim body 11 is cylindrical, and the outer surface of the wheel rim body 11 is the surface of the wheel rim body 11 facing the tire 30.

[0038] Among them, the annular noise reduction assembly 20 is elastic, and the inner diameter of the annular noise reduction assembly 20 is smaller than the outer diameter of the wheel rim body 11. During the assembly of the annular noise reduction assembly 20, the inner diameter of the annular noise reduction assembly 20 can be expanded by a tool clamp and sleeved on the outer surface of the wheel rim body 11. After the annular noise reduction assembly 20 is sleeved on the outer surface of the wheel rim body 11, the annular noise reduction assembly 20 will be expanded by the extrusion of the wheel rim body 11, and the annular noise reduction assembly 20 has an elastic restoring force towards the wheel rim body 11. The action of the elastic restoring force causes the annular noise reduction assembly 20 to generate a holding force on the wheel rim body 11, so that the inner surface of the annular noise reduction assembly 20 can be tightly fitted with the outer surface of the wheel rim body 11, thereby realizing the interference connection between the annular noise reduction assembly 20 and the wheel rim body 11.

[0039] During the driving of the vehicle, the excitation of the tire 30 by the road surface will cause the wheel rim 10 to vibrate, and when the vibration is transmitted to the annular noise reduction assembly 20, the annular noise reduction assembly 20 can absorb the vibration energy and convert it into heat energy or other forms of energy, thereby inhibiting the generation of resonance, reducing the propagation of vibration, and thereby reducing the noise generated by the vibration of the wheel rim 10, which can effectively improve the driving and riding experience of the user.

[0040] By sleeving the annular noise reduction assembly 20 on the outer surface of the rim body 11 and making the annular noise reduction assembly 20 and the rim body 11 interference fit, on the one hand, the interference fit of the annular noise reduction assembly 20 and the rim body 11 can ensure that the annular noise reduction assembly 20 is closely attached to the surface of the rim body 11 to form a stable sound insulation barrier, avoiding the risk that noise is transmitted from the area where the bubbles exist between the annular noise reduction assembly 20 and the rim body 11, and can effectively improve the noise reduction effect of the annular noise reduction assembly 20; on the other hand, the connection mode of the annular noise reduction assembly 20 and the rim body 11 will not be affected by the temperature of the rim body 11 and the driving conditions of the vehicle, that is, even if the temperature of the rim body 11 is very high or the vehicle is jolted or vibrates during driving, the annular noise reduction assembly 20 and the rim body 11 can maintain a stable connection state, so that the annular noise reduction assembly 20 can continuously play a noise reduction role, and the noise reduction effect of the annular noise reduction assembly 20 can be further improved, effectively improving the driving and riding experience of the user.

[0041] In some embodiments, please refer to Figure 3 , the annular noise reduction assembly 20 comprises a primer layer 21 and a polyurethane foam layer 22 arranged in layers, and the primer layer 21 is arranged on the side of the polyurethane foam layer 22 facing the rim body 11.

[0042] The primer layer 21 can have a ring structure, and the polyurethane foam layer 22 can be formed on the primer layer 21 by foaming. For example, first, the outer surface of the primer layer 21 is cleaned or polished to improve the adhesion of the polyurethane foam layer 22 to the primer layer 21, thereby improving the connection strength between the primer layer 21 and the polyurethane foam layer 22; then the polyurethane foaming agent is applied to the outer surface of the primer layer 21, and finally the primer layer 21 coated with the polyurethane foaming agent is placed in a mold for foaming. In the foaming process, the polyurethane foaming agent will gradually expand to form a porous polyurethane foam layer 22.

[0043] Since the primer layer 21 has a ring structure, there is no connection mark along the circumference of the rim body 11, which helps to maintain the continuity and integrity of the annular noise reduction assembly 20, and can effectively improve the noise reduction effect of the annular noise reduction assembly 20.

[0044] Please refer to Figures 4 to 5 , Figure 4 is a sectional view of a part of the structure of the annular noise reduction assembly of the vehicle wheel assembly provided in the present application; Figure 5 is a structural schematic view of another embodiment of the annular noise reduction assembly of the vehicle wheel assembly provided in the present application.

[0045] In some embodiments, the annular noise reduction assembly 20 comprises a noise reduction body 20a and a connecting portion 20b connected between two ends of the noise reduction body 20a along the circumferential direction of the rim body 11. The noise reduction body 20a comprises a primer layer 21 and a polyurethane foam layer 22 arranged in a stacked manner, and the primer layer 21 is arranged on the side of the polyurethane foam layer 22 facing the rim body 11.

[0046] The noise reduction body 20a can have a rectangular structure. The connecting portion 20b can have a solid structure for connecting the two ends of the noise reduction body 20a along the circumferential direction of the rim body 11. The connecting portion 20b can also be a connecting area of the two ends of the noise reduction body 20a along the circumferential direction of the rim body 11, and the noise reduction body 20a can be connected by a bonding process to form an annular structure. If the connecting portion 20b has a solid structure, the material of the connecting portion 20b can be the same as that of the primer layer 21.

[0047] Specifically, the primer layer 21 can have a rectangular structure, and the polyurethane foam layer 22 can be formed on the side of the primer layer 21 away from the rim body 11 by foaming to form the noise reduction body 20a, and then the two ends of the noise reduction body 20a along the length direction are connected together by the connecting portion 20b or the bonding process to form the annular noise reduction assembly 20. Alternatively, the two ends of the primer layer 21 along the length direction are first connected together by the connecting portion 20b or the bonding process to form a ring-shaped primer layer 21, and then the polyurethane foam layer 22 is formed on the outer surface of the primer layer 21 by foaming to form the annular noise reduction assembly 20. The specific way of forming the polyurethane foam layer 22 on the primer layer 21 by foaming can refer to the above embodiments, which will not be described here.

[0048] In some embodiments, the two ends of the noise reduction body 20a along the length direction can be connected by a direct bonding method, which is a bonding process. For example, the two ends of the noise reduction body along the length direction are bonded together after being heated and pressurized. The two ends of the noise reduction body 20a along the length direction are connected by the direct bonding method, which has high connection strength, so that the connecting area of the annular noise reduction assembly 20 will not be affected by temperature. Even if the temperature of the rim body 11 is very high during driving of the vehicle, the connecting area of the annular noise reduction assembly 20 will not be broken, which can effectively improve the noise reduction effect of the annular noise reduction assembly 20.

[0049] In some embodiments, the primer layer 21 comprises a rubber layer, a silicone layer or a dandelion latex layer, but is not limited thereto.

[0050] The rubber layer, the silica gel layer and the dandelion rubber layer all have elasticity, so that when the annular noise reduction assembly 20 is sleeved on the outer surface of the rim body 11, the base layer 21 can generate a holding force on the rim body 11, so that the inner surface of the base layer 21 can be tightly attached to the outer surface of the rim body 11, thereby realizing the interference connection between the annular noise reduction assembly 20 and the rim body 11.

[0051] Please refer to Figure 6 , Figure 6 is a structural schematic diagram of a third embodiment of the annular noise reduction assembly of the wheel assembly provided by the present application. In some embodiments, the annular noise reduction assembly 20 further comprises an adhesive layer 23. The adhesive layer 23 is arranged on the side of the base layer 21 away from the polyurethane foam layer 22. The adhesive layer 23 is used to adhere the annular noise reduction assembly 20 to the outer surface of the rim body 11.

[0052] The adhesive layer 23 can be a double-sided tape, a polyurethane sealing adhesive, an acrylic adhesive, a rubber-based adhesive or a silicone-based adhesive, but is not limited thereto. The double-sided tape can be a 3M4008 double-sided tape, which is a double-sided tape with a polyurethane foam substrate, has high tensile force, high shear strength, high temperature resistance and the like, and will not be affected by the temperature and vibration of the rim 10 and fail. The polyurethane sealing adhesive, the acrylic adhesive and the rubber-based adhesive have the advantages of good flexibility, high bonding strength and the like, are suitable for occasions that bear relatively large pressure and impact, and can adapt to the particularity of the rim 10 working in a vibrating environment. The silicone-based adhesive has excellent heat and cold resistance, is suitable for environments with large temperature changes, and can adapt to the particularity of the rim 10 working in an environment with changing temperatures.

[0053] The adhesive layer 23 is used to adhere the annular noise reduction assembly 20 to the outer surface of the rim body 11, that is, on the basis of the interference connection between the annular noise reduction assembly 20 and the rim body 11, the adhesive layer 23 is arranged on the side of the base layer 21 away from the polyurethane foam layer 22, so as to adhere the annular noise reduction assembly 20 to the outer surface of the rim body 11. On the one hand, the adhesive layer 23 has adhesion, which can further enhance the connection strength between the annular noise reduction assembly 20 and the rim body 11 on the basis of the interference connection between the annular noise reduction assembly 20 and the rim body 11. On the other hand, the adhesive layer 23 can disperse and relieve local stress, reduce the risk of cracking of the annular noise reduction assembly 20 caused by stress concentration, improve the reliability and durability of the annular noise reduction assembly 20, and thereby improve the service life of the annular noise reduction assembly 20. On the third hand, the adhesive layer 23 can form a sealing layer between the base layer 21 and the rim body 11, prevent moisture, dust or other liquids and particulate matters from entering between the base layer 21 and the rim body 11, and thereby prevent the noise reduction effect of the annular noise reduction assembly 20 from being affected, so as to further improve the noise reduction effect of the annular noise reduction assembly 20.

[0054] In addition, since the annular noise reduction assembly 20 is in interference connection with the rim body 11, even if the bonding layer 23 has aging problems, the annular noise reduction assembly 20 can be stably sleeved on the outer surface of the rim body 11 and will not fall off.

[0055] In some embodiments, the difference between the outer diameter of the rim body 11 and the inner diameter of the annular noise reduction assembly 20 is 0.5mm-3mm.

[0056] The difference between the outer diameter of the rim body 11 and the inner diameter of the annular noise reduction assembly 20 can be 0.5mm, 0.8mm, 1mm, 1.25mm, 1.4mm, 1.55mm, 1.7mm, 1.85mm, 2mm, 2.2mm, 2.5mm, 2.75mm, 2.8mm, 3mm, etc., but is not limited thereto. Alternatively, the difference between the outer diameter of the rim body 11 and the inner diameter of the annular noise reduction assembly 20 is 1mm-2mm. The specific difference between the outer diameter of the rim body 11 and the inner diameter of the annular noise reduction assembly 20 can be selected according to actual conditions, as long as the inner diameter of the annular noise reduction assembly 20 is smaller than the outer diameter of the rim body 11, and the annular noise reduction assembly 20 can be in interference connection with the rim body 11 after being sleeved on the outer surface of the rim body 11.

[0057] In some embodiments, the thickness of the polyurethane foam layer 22 is 15mm-25mm.

[0058] The thickness of the polyurethane foam layer 22 can be 15mm, 15.5mm, 15.8mm, 16mm, 16.25mm, 16.6mm, 16.85mm, 17mm, 17.5mm, 17.9mm, 18mm, 18.5mm, 18.8mm, 19mm, 19.5mm, 20mm, 20.5mm, 20.75mm, 21mm, 21.5mm, 22mm, 22.25mm, 22.8mm, 23mm, 23.5mm, 24mm, 24.5mm, 25mm, etc., but is not limited thereto. Alternatively, the thickness of the polyurethane foam layer 22 is 20mm. The specific thickness of the polyurethane foam layer 22 can be selected according to the size of the rim 10 and the size of the annular noise reduction assembly 20, etc.

[0059] In some embodiments, the thickness of the primer layer 21 is 3mm-6mm.

[0060] The thickness of the base layer 21 can be 3 mm, 3.2 mm, 3.5 mm, 3.88 mm, 4 mm, 4.3 mm, 4.5 mm, 4.88 mm, 5 mm, 5.25 mm, 5.5 mm, 5.7 mm, 5.85 mm, or 6 mm. Alternatively, the thickness of the base layer 21 is 4 mm-5 mm. The specific thickness of the base layer 21 can be selected according to the size of the rim 10 and the size of the annular noise reduction assembly 20.

[0061] In some embodiments, the wheel assembly 100 further comprises a tire 30. The tire 30 is mounted on the two mounting portions 12 to form a cavity 10a between the rim body 11 and the tire 30, and the annular noise reduction assembly 20 is sleeved on the surface of the rim body 11 facing the cavity 10a.

[0062] The cavity 10a is used to contain air. During the driving of the vehicle, when the tire 30 is impacted, the air in the cavity 10a can play a buffering role, can absorb the vibration of the tire 30, and can reduce the transmission of the vibration from the wheel assembly 100 to the vehicle body, thereby improving the stability of the vehicle driving.

[0063] In some embodiments, please refer to Figure 1 The two mounting portions 12 are each provided with a groove 121 arranged in the circumferential direction of the rim body 11, and the tire 30 is embedded in the corresponding groove 121 on both sides of the axis of the rim body 11.

[0064] The tire 30 can be provided with a protrusion 31 matched with the groove 121 on both sides of the axis of the rim body 11, and when the tire 30 is mounted on the mounting portion 12, the protrusion 31 of the tire 30 is completely embedded in the groove 121, so that the tire 30 is sealingly connected with the mounting portion 12. The protrusion 31 can be a rubber strip or a silica gel strip, but is not limited thereto.

[0065] In some embodiments, the mounting portion 12 can be provided with a claw groove (not shown) uniformly distributed in the circumferential direction thereof, and the tire 30 can be provided with a clamping claw (not shown) matched with the claw groove of the mounting portion 12. The claw groove of the mounting portion 12 can be equidistantly spaced in the circumferential direction thereof. When the tire 30 is mounted on the mounting portion 12, the clamping claw is clamped in the claw groove, so that the connection between the mounting portion 12 and the tire 30 is achieved. The clamping claw and the claw groove can ensure that the mounting portion 12 and the tire 30 do not come off during the driving of the vehicle.

[0066] In another aspect of the present application, a vehicle is provided. The vehicle comprises the wheel assembly 100 in any of the above embodiments.

[0067] The vehicle provided in the application has all the technical effects brought by the technical solutions of the wheel assembly 100 embodiments, and thus, the details are not described herein.
