Description

Technical Field

[0001] The present application relates to the technical field of tires, and in particular to a wheel structure and a vehicle. Background Art

[0002] The process of a car moving at high speed is the process of squeezing air at high speed. If the air is squeezed, it will inevitably be subject to the reaction force of the air. The reaction force generated by the air on a high-speed car is proportional to the square of the speed. The faster the speed, the greater the air resistance. The air resistance encountered by the vehicle is also related to the windward area of ​​the vehicle itself and the guiding effect of the air. Generally speaking, the larger the windward area, the greater the air resistance at the same speed. However, under the same windward area, the better the diversion design of the car model, the smaller the air resistance will be.

[0003] A vehicle tire is a component of a vehicle that directly contacts the ground and enables the vehicle to move. It generally includes a bead, a rim, and a hub. The vehicle tire is mounted on the vehicle's drive shaft, and the vehicle has a wheel cover that reduces the wind resistance of the vehicle tire.

[0004] However, after the tire bead and the rim are assembled, there is a transition groove at the edge of the tire bead and the wheel hub, and the transition groove is V-shaped, which not only increases the wind resistance of the vehicle tire when running, but also causes foreign objects to be stuck in the transition groove, affecting the safety performance of the vehicle tire.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the implementation of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein. In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner.

[0047] As mentioned in the background technology: the process of a car moving at high speed is the process of squeezing the air at high speed. Then squeezing the air will inevitably be subject to the reaction force of the air. The reaction force generated by the air on a high-speed car is proportional to the square of the speed. The faster the speed, the greater the air resistance. The air resistance encountered by the vehicle is also related to the windward area of ​​the vehicle itself and the guiding effect of the air. Generally speaking, the larger the windward area, the greater the air resistance at the same speed, but under the same windward area, the better the diversion design of the car model, the smaller the air resistance will be.

[0048] A vehicle tire is a component of a vehicle that directly contacts the ground and enables the vehicle to move. It generally includes a bead, a rim, and a hub. The vehicle tire is mounted on the vehicle's drive shaft, and the vehicle has a wheel cover that reduces the wind resistance of the vehicle tire.

[0049] However, after the tire bead and the rim are assembled, there is a transition groove at the edge of the tire bead and the wheel hub, and the transition groove is V-shaped, which not only increases the wind resistance of the vehicle tire when running, but also causes foreign objects to be stuck in the transition groove, affecting the safety performance of the vehicle tire.

[0050] Moreover, the tires of new energy vehicles generally have a low aspect ratio and a low tire height, which makes them prone to tire bulging and rim cracking. Compared with traditional fuel vehicles, new energy vehicles have a greater vehicle load, lower tire height, and poor tire support, which increases steering response speed and reduces steering rear axle follow-up.

[0051] In order to solve the technical problems mentioned above, the present application provides a wheel structure and a vehicle. The wheel structure is provided with a tire bead, a rim and a plugging piece. The rim is installed in the sub-mouth of the tire bead, and an annular transition groove is formed between the rim and the sub-mouth; the plugging piece is installed in the transition groove, and the plugging piece is located on the side of the tire bead and the rim facing the outside of the vehicle. The plugging piece is configured to block the transition groove to prevent airflow and foreign matter from entering the transition groove. The wind resistance of the vehicle tire during driving is reduced, foreign matter is prevented from being stuck in the transition groove, and the safety performance of the vehicle tire is ensured; and the setting of the plugging piece increases the buffering of the vehicle tire, the radial and lateral support of the vehicle tire, the radial stiffness of the vehicle tire, and the support of the lateral force of the vehicle tire, reduces the gap between the tire bulge and the rim crack, and improves the steering response speed and the steering rear axle followability.

[0052] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0053] refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a wheel structure, including a tire bead 100 , a rim 200 and a sealing member 300 .

[0054] The rim 200 is installed in the sub-mouth of the tire bead 100, and an annular transition groove 400 is formed between the rim 200 and the sub-mouth.

[0055] The blocking member 300 is installed in the transition groove 400 and is located on the side of the tire bead 100 and the rim 200 facing the outside of the vehicle. The blocking member 300 is configured to block the transition groove 400 to prevent airflow and foreign matter from entering the transition groove 400 .

[0056] Among them, when the tire bead 100 is installed on the wheel hub, the outer side of the wheel hub is stuck on the middle opening of the tire bead 100, and there is a certain height difference between the outer side of the wheel hub and the middle opening, thereby forming an annular transition groove 400. The transition groove 400 has two locations between the tire bead 100 and the wheel hub, one of which is located on the side of the vehicle tire facing the outside of the vehicle, and the other transition groove 400 is located on the side of the vehicle tire facing the inside of the vehicle. Among them, the transition groove 400 located on the outside of the vehicle is directly exposed to the outside world, which not only increases the wind resistance of the vehicle tire when running, but also there is a situation where foreign objects are stuck in the transition groove 400, affecting the safety performance of the vehicle tire.

[0057] Exemplarily, the cross section of the transition groove 400 is V-shaped.

[0058] Exemplarily, the blocking member 300 is arranged in an annular shape as a whole, and the cross section of the blocking member 300 is also V-shaped, so that the blocking member 300 completely blocks the transition groove 400.

[0059] By adopting the above technical solution, by setting the sealing member 300, the sealing member 300 blocks the transition groove 400 between the tire bead 100 and the rim 200, thereby preventing airflow and foreign matter from entering the transition groove 400, reducing the wind resistance of the vehicle tire when running, avoiding foreign matter from being stuck in the transition groove 400, and ensuring the safety performance of the vehicle tire.

[0060] The setting of the sealing member 300 can also increase the cushioning of the vehicle tire, the radial and lateral support of the vehicle tire, the radial stiffness of the vehicle tire and the support of the lateral force of the vehicle tire, reduce the gap between the tire bulge and the crack of the rim 200, and improve the steering response speed and the steering rear axle follow-up.

[0061] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The blocking member 300 includes a connecting portion 310 and a blocking portion 320 . The connecting portion 310 is inserted into the transition groove 400 . The blocking portion 320 is located at the notch of the transition groove 400 , and is used to cover the notch of the transition groove 400 .

[0062] Exemplarily, the blocking portion 320 is a blocking ring, and the connecting portion 310 is a plurality of connecting blocks, the plurality of connecting blocks are evenly spaced and connected to the blocking ring, and the connecting blocks are inserted into the transition groove 400 .

[0063] Exemplarily, the rim 200 and the sub-mouth have a snap-in groove at the transition groove 400 , and the connecting portion 310 has a snap-in block, and the connecting portion 310 is snap-into the snap-in groove of the transition groove 400 through the snap-in block.

[0064] By adopting the above technical solution, by setting the connecting part 310 and the blocking part 320, the connecting part 310 is used to install the blocking part 320 in the transition groove 400, and the blocking part 320 is used to cover the notch of the transition groove 400, so as to facilitate the installation of the blocking member 300 in the transition groove 400.

[0065] In some embodiments, the connection portion 310 is bonded to the sub-mouth and the rim 200 respectively.

[0066] Exemplarily, the glue material is acrylate.

[0067] By adopting the above technical solution, it is convenient to connect the connecting portion 310 with the sub-mouth and the rim 200.

[0068] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The connecting portion 310 has a first connecting surface 311, and the first connecting surface 311 matches the end surface of the sub-mouth located in the transition groove 400, so that the first connecting surface 311 abuts against the sub-mouth.

[0069] The end surface of the sub-port located in the transition groove 400 is an arc surface and is annular in shape as a whole. The first connecting surface 311 is also annular in shape as a whole.

[0070] By adopting the above technical solution and providing the first connecting surface 311, the contact area between the connecting portion 310 and the sub-mouth is increased, so that after the connecting portion 310 and the sub-mouth are bonded, the connection strength between the connecting portion 310 and the sub-mouth is ensured.

[0071] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The connecting portion 310 has a second connecting surface 312 , and the second connecting surface 312 matches the end surface of the rim 200 located in the transition groove 400 , so that the second connecting surface 312 abuts against the rim 200 .

[0072] The end surface of the rim 200 located in the transition groove 400 is an arc surface and is annular in shape as a whole. The second connecting surface 312 is also annular in shape as a whole.

[0073] By adopting the above technical solution and providing the second connecting surface 312 , the contact area between the connecting portion 310 and the rim 200 is increased, so that after the connecting portion 310 and the rim 200 are bonded together, the connection strength between the connecting portion 310 and the rim 200 is ensured.

[0074] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The end surface of the blocking portion 320 away from the transition groove 400 is a curved surface 321 .

[0075] By adopting the above technical solution, the curved surface 321 on the blocking portion 320 guides the air flow passing through the blocking portion 320 away from the end surface of the transition groove 400, further reducing the air resistance encountered by the vehicle tire during running.

[0076] In some embodiments, the blocking member 300 is an elastic member.

[0077] Exemplarily, the elastic material may be one of rubber material, elastomeric plastic, elastic foam material and elastic textile.

[0078] By adopting the above technical solution and setting the blocking member 300 as an elastic member, the blocking member 300 can be deformed together with the tire bead 100 and the rim 200, thereby ensuring the blocking effect of the blocking member 300 on the transition groove 400.

[0079] In some embodiments, the elastic member is a natural rubber member or an isoprene rubber member.

[0080] Among them, natural rubber parts have high mechanical strength, good flexural fatigue resistance and elasticity.

[0081] Isoprene rubber parts have high resistance to high temperature, corrosion and wear.

[0082] By adopting the above technical scheme, the elastic part is a natural rubber part, which can make the elastic part have higher mechanical strength, good flexural fatigue resistance and elasticity; the elastic part is an isoprene rubber part, which can make the elastic part have higher high temperature resistance, corrosion resistance and wear resistance.

[0083] In some embodiments, the blocking member 300 is arranged in a ring shape so that the blocking member 300 blocks the annular transition groove 400 .

[0084] By adopting the above technical solution, by setting the sealing member 300 in a ring shape, the sealing member 300 completely blocks the annular transition groove 400, thereby preventing airflow and foreign matter from entering the transition groove 400, reducing the wind resistance of the vehicle tire when running, preventing foreign matter from being stuck in the transition groove 400, and ensuring the safety performance of the vehicle tire.

[0085] An embodiment of the present application also discloses a vehicle, comprising a vehicle body and a wheel structure according to any one of the above embodiments installed on the vehicle body.

[0086] Among them, the structure and principle of the wheel structure have been clearly explained in the above embodiments and will not be elaborated here one by one.

[0087] The vehicle body can be a traditional fuel vehicle or a new energy vehicle.

[0088] By adopting the above technical solution, when the vehicle body is a traditional fuel vehicle, the wheel structure not only reduces the wind resistance of the vehicle tires when running, but also avoids foreign objects from being stuck in the transition groove 400, thereby ensuring the safety performance of the vehicle tires.

[0089] When the vehicle body is a new energy vehicle, the wheel structure not only reduces the wind resistance of the vehicle tire when traveling, avoids foreign objects from being stuck in the transition groove 400, and ensures the safety performance of the vehicle tire; but also can increase the buffering of the vehicle tire, the radial and lateral support of the vehicle tire, the radial stiffness of the vehicle tire and the support of the lateral force of the vehicle tire, reduce the gap between the tire bulge and the crack of the rim 200, and improve the steering response speed and the steering rear axle follow-up.
