Technical Field
[0001] This application relates to the field of wheel technology, and in particular to a pneumatic tire, wheel, and vehicle. Background Technology
[0002] Most bicycles and scooters on the market use either pneumatic tires or airless tires. Pneumatic tires offer advantages such as lightness and comfort, but they cannot eliminate the risks of punctures and blowouts. Airless tires can avoid the risks of punctures and blowouts, but they can come off during use, compromising rider safety. Utility Model Content
[0003] Therefore, it is necessary to provide a tire, wheel, and vehicle that do not require inflation, which can avoid the risk of tire slippage and ensure safe use.
[0004] In a first aspect, this application provides a pneumatic tire, comprising:
[0005] Tire body, the tire body having an outer tread; and
[0006] A boss is provided on the side of the tire body away from the outer tire tread. The boss surrounds and forms an assembly hole for the wheel hub to be inserted. The side of the boss away from the tire body is used to fit against the outer peripheral surface of the wheel hub.
[0007] When assembling the aforementioned airless tire, the airless tire is fitted onto the outside of the rim, with the side of the protrusion facing away from the tire body seamlessly fitting against the outer circumference of the rim. This increases the binding force between the airless tire and the rim, preventing the airless tire from softening due to excessive temperature during vehicle operation, thus avoiding the airless tire from detaching from the rim and ensuring safety in use.
[0008] In one embodiment, the tire body further has opposing first and second sidewalls, at least one of the first and second sidewalls having a first engaging portion for engaging with the wheel hub.
[0009] In one embodiment, the first snap-fit portion is provided with a snap-fit groove that extends circumferentially along the tire body.
[0010] In one embodiment, the inner tread has a plurality of grooves on the side opposite to the tire body, and the plurality of grooves are spaced apart circumferentially along the tire body.
[0011] In one embodiment, the outer tire tread is provided with tire tread.
[0012] In one embodiment, the outer tire tread is provided with tread grooves and an outlet, the tread grooves being connected to the outlet so that impurities in the tread grooves can be discharged to the outside of the tire body through the outlet.
[0013] In one embodiment, the tire body further has opposing first and second shoulders, and the tread grooves include a first tread groove, a second tread groove, a third tread groove, and a fourth tread groove; the tread pattern includes a first tread block, a second tread block, and a third tread block, the first tread block being located on the outer tire tread near the first shoulder, the second tread block being located on the outer tire tread near the second shoulder, and the third tread block being located between the first tread block and the second tread block. The first tread groove is formed by the third tread block spaced apart, and the second tread groove is formed by the second tread block spaced apart from the third tread block. Both the first tread groove and the second tread groove extend circumferentially along the tire body. The first tread block is provided with the third tread groove, and the second tread block is provided with the fourth tread groove. The first tread groove is connected to the third tread groove, and the second tread groove is connected to the fourth tread groove. The groove walls of both the third tread groove and the fourth tread groove are provided with the outlet.
[0014] Secondly, this application also provides a wheel, comprising:
[0015] The pneumatic tires of any of the above; and
[0016] The wheel hub is located in the mounting hole, and the outer peripheral surface of the wheel hub is in contact with the side of the boss away from the tire body.
[0017] When assembling the aforementioned wheels, the pneumatic tire is fitted over the rim, with the side of the protrusion facing away from the tire body seamlessly fitting against the outer circumference of the rim. This increases the binding force between the pneumatic tire and the rim, preventing the pneumatic tire from softening due to excessive temperature during vehicle operation, thus avoiding the pneumatic tire from detaching from the rim and ensuring safety in use.
[0018] In one embodiment, the tire body further has opposing first and second sidewalls, at least one of the first and second sidewalls being provided with a groove extending circumferentially along the tire body;
[0019] The wheel hub is provided with a buckle, which is located in the buckle groove and engages with the buckle groove.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0030] See Figure 1 and Figure 5 An embodiment of this application provides a wheel including a pneumatic tire 10 and a rim 20. The pneumatic tire 10 includes a tire body 11, which has an outer tread 1111 and an inner tread 1121, with the outer tread 1111 and the inner tread 1121 disposed opposite to each other. The inner tread 1121 surrounds and forms a mounting hole 113, and the rim 20 is disposed within the mounting hole 113.
[0031] See Figure 1 and Figure 5 The tire body 11 includes a tire body 111 and a boss 112. An outer tread 1111 is provided on the tire body 111. The boss 112 is provided on the side of the tire body 111 opposite to the outer tread 1111, and the boss 112 surrounds and forms a mounting hole 113. An inner tread 1121 is provided on the side of the boss 112 opposite to the tire body 111. The side of the boss 112 opposite to the tire body 111 is in contact with the outer peripheral surface of the rim 20.
[0032] During assembly, the airless tire 10 is fitted over the rim 20, and the side of the boss 112 facing away from the tire body 111 fits seamlessly with the outer circumference of the rim 20. This increases the binding force between the airless tire 10 and the rim 20, preventing the airless tire 10 from softening due to excessive temperature during vehicle operation, thus avoiding the airless tire 10 from detaching from the rim 20 and ensuring safety in use.
[0033] In one embodiment, see Figure 3 and Figure 4 The tire body 111 also has a first tire sidewall 1112 and a second tire sidewall 1113, which are disposed opposite to each other. At least one of the first tire sidewall 1112 and the second tire sidewall 1113 is provided with a first snap-fit portion.
[0034] Further, see Figure 5 The hub 20 is provided with a second snap-fit part, which is used to snap-fit with the first snap-fit part.
[0035] During assembly, the airless tire 10 is fitted onto the wheel hub 20, and the first snap-fit part and the second snap-fit part are engaged. This allows the airless tire 10 to be secured to the wheel hub 20, preventing the airless tire 10 from separating from the wheel hub 20, which helps improve safety during use.
[0036] In one embodiment, see Figure 4 and Figure 5 Both the first tire sidewall 1112 and the second tire sidewall 1113 are provided with a first engaging portion, and both ends of the wheel hub 20 along its axial direction are provided with a second engaging portion. In this way, the firmness of the engagement between the pneumatic tire 10 and the wheel hub 20 can be improved, further preventing the pneumatic tire 10 from separating from the wheel hub 20, and further improving the safety of use.
[0037] In one embodiment, the first snap-fit portion is located on the side of the first tire sidewall 1112 and the second tire sidewall 1113 near the boss 112. During assembly, after the airless tire 10 is fitted onto the wheel hub 20, the first snap-fit portion is located near the boss 112, which facilitates the snap-fit engagement between the first snap-fit portion and the second snap-fit portion, thereby realizing the assembly of the airless tire 10 and the wheel hub 20.
[0038] In one embodiment, see Figure 4 and Figure 5 The first engaging portion has a groove 11121 that extends circumferentially along the tire body 11. The second engaging portion has a buckle 21 that fits into the groove 11121. During assembly, the buckle 21 is placed within the groove 11121 to connect the pneumatic tire 10 to the wheel rim 20. This eliminates the need for additional tools, improving assembly efficiency, reducing assembly steps, and lowering assembly complexity. Furthermore, the tight fit between the groove 11121 and the buckle 21 ensures the pneumatic tire 10 remains stable under vibrations and bumps during vehicle operation, preventing it from loosening and separating from the wheel rim 20.
[0039] Of course, in other embodiments, the first engaging portion is provided with a buckle 21. The second engaging portion is provided with a slot 11121, which extends circumferentially along the hub 20.
[0040] In one embodiment, see Figure 1 and Figure 3 The inner tread 1121 is provided with a plurality of grooves 1122. Optionally, the plurality of grooves 1122 are spaced apart along the circumference of the tire body 11. This arrangement helps to reduce the overall weight of the pneumatic tire 10, thereby achieving lightweighting of the pneumatic tire 10.
[0041] It should be noted that a contact portion is formed between two adjacent grooves 1122 that fits against the wheel hub 20. After the airless tire 10 is fitted onto the wheel hub 20, the outer circumferential surface of the wheel hub 20 fits against the contact portion. Before the impact force is fully transmitted to the wheel hub 20, the contact portion will be compressed and arched into the grooves 1122 on both sides, undergoing elastic deformation. This causes the two sides of the contact portion to be subjected to the rebound internal stress generated by the deformation of the structure itself, which offsets part of the impact force. This effectively absorbs the impact force acting on the airless tire 10, ensuring that the airless tire 10 has good cushioning performance and effectively improving the comfort of riding or driving the vehicle.
[0042] It should be noted that a certain gap is reserved between the bottom of the groove 1122 and the outer tire tread 1111 to ensure that the pneumatic tire 10 has a certain support.
[0043] In one embodiment, see Figure 1 The outer tread 1111 has tread patterns 114. These tread patterns 114 increase the contact area between the pneumatic tire 10 and the ground, improving the tire's grip and allowing it to better conform to the road surface, reducing braking distance. They also effectively prevent slippage and improve vehicle safety in rainy weather. Furthermore, because the outer tread 1111 has tread patterns 114, the stress on different parts of the pneumatic tire 10 is distributed to a certain extent during driving, preventing excessive localized wear, extending the overall service life of the pneumatic tire 10, and also enhancing its strength.
[0044] In one embodiment, the outer tire tread 1111 is provided with tread grooves 115 and an outlet, and the tread grooves 115 are connected to the outlet. With this configuration, if water or mud is encountered during vehicle operation, the water or mud can be quickly discharged through the tread grooves 115 and the outlet, thereby enhancing the grip and driving performance of the pneumatic tire 10.
[0045] In one embodiment, see Figure 2 The tire body 111 also has a first shoulder 1114 and a second shoulder 1115.
[0046] Further, see Figure 2 The tire tread 114 includes a first tread block 1141, a second tread block 1142, and a third tread block 1143. The first tread block 1141 is located on the side of the outer tire tread 1111 near the first shoulder 1114, the second tread block 1142 is located on the side of the outer tire tread 1111 near the second shoulder 1115, and the third tread block 1143 is located between the first tread block 1141 and the second tread block 1142. The first tread block 1141 and the third tread block 1143 form a first tread groove 1151, which extends circumferentially along the tire body 11. The second tread block 1142 and the third tread block 1143 form a second tread groove 1152, which extends circumferentially along the tire body 111.
[0047] The first tread block 1141 has a third tread groove 1153, which communicates with the first tread groove 1151. The second tread block 1142 has a fourth tread groove 1154, which communicates with the second tread groove 1152. Both the third and fourth tread grooves 1153 and 1154 have drainage outlets on their walls. This design allows water and mud to be quickly discharged from the first tread groove 1151 through the third tread groove 1153 and the drainage outlets, and from the second tread groove 1152 through the fourth tread groove 1154 and the drainage outlets, thus enhancing the grip and driving performance of the pneumatic tire 10.
[0048] This application also provides a vehicle including the pneumatic tire 10 of any of the above embodiments.
[0049] Optionally, the vehicle may include, but is not limited to, bicycles, scooters, etc.
[0050] During assembly, the airless tire 10 is fitted over the rim 20, and the side of the boss 112 facing away from the tire body 111 fits seamlessly with the outer circumference of the rim 20. This increases the binding force between the airless tire 10 and the rim 20, preventing the airless tire 10 from softening due to excessive temperature during driving, thus avoiding the airless tire 10 from detaching from the rim 20 and ensuring safety in use.
