Description

Technical Field

[0001] This application relates to the field of wheel technology, and more particularly to a wheel and a vehicle. Background Technology

[0002] Currently, most wheels are pneumatic tires. These pneumatic wheel assemblies mainly consist of a rim, spokes, and an inflatable tire. Their working principle involves inflating the tire with high-pressure gas, using the gas pressure to support the tire's shape, and relying on the compressibility of the gas to achieve a certain degree of shock absorption. Under high-speed driving conditions, if an inflatable tire bursts due to puncture, aging, or abnormal pressure, the internal pressure drops sharply, causing the wheel to lose its support. This can easily lead to loss of steering control, rollovers, and other accidents, posing a significant threat to the lives of the driver and passengers. Summary of the Invention

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] The applicant noted that currently, most wheels are pneumatic tires. These pneumatic wheel assemblies mainly consist of a rim, spokes, and an inflatable tire. Their working principle involves inflating the tire with high-pressure gas, using the gas pressure to support the tire's shape, and relying on the compressibility of the gas to achieve a certain degree of shock absorption. Under high-speed driving conditions, if an inflatable tire bursts due to puncture, aging, or abnormal pressure, the internal pressure drops sharply, causing the wheel to lose its support. This greatly increases the risk of loss of steering control, rollovers, and other accidents, posing a significant threat to the lives of the driver and passengers. Furthermore, the stiffness of pneumatic tires relies heavily on internal pressure regulation, which has a limited range and low precision, making it difficult to simultaneously meet the needs of vehicles under different driving conditions.

[0023] In view of this, this application provides a wheel, including a rim 1, spokes 2, a tire 3, an elastic element 4, and a support element 5; the spokes 2 are disposed at one axial end of the rim 1 and connected to the rim 1; the tire 3 is disposed on the outer periphery of the rim 1 and connected to the rim 1, and the tire 3 has a receiving cavity 30; the elastic element 4 is filled in the receiving cavity 30, and the support element 5 is embedded in the elastic element 4, the support element 5 being used to improve the stiffness of the elastic element 4. With this configuration, the elastic element 4 fills the receiving cavity 30 of the tire 3 to provide support, replacing the traditional pneumatic tire 3. This eliminates the need to rely on gas pressure for wheel load bearing, avoiding the risk of vehicle loss of control due to tire blowouts at high speeds. Even if the elastic element 4 is partially damaged, the remaining portion can still provide basic support, avoiding the complete failure of a traditional pneumatic tire after a blowout, thereby improving vehicle driving safety; furthermore, the support element 5 is embedded in the elastic element 4, forming a cooperative support structure with the elastic element 4, and the wheel stiffness can be adjusted by adjusting the structure of the support element 5.

[0024] The wheels and vehicles of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0025] This application provides a wheel; please refer to [the relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the wheel provided in an exemplary embodiment of this application. Figure 2This is an exploded view of a wheel provided in an exemplary embodiment of this application. The wheel includes a rim 1, spokes 2, a tire 3, an elastic element 4, and a support element 5. The spokes 2 are disposed at one axial end of the rim 1 and connected to the rim 1. The tire 3 is disposed on the outer periphery of the rim 1 and connected to the rim 1, and the tire 3 has a receiving cavity 30. (Refer to...) Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the wheel structure provided in another exemplary embodiment of this application. Figure 4 yes Figure 3 In the sectional view (AA), the elastic element 4 is filled within the receiving cavity 30, and the support element 5 is embedded within the elastic element 4. The support element 5 is used to increase the stiffness of the elastic element 4. This configuration allows the elastic element 4 to fill the receiving cavity 30 of the tire 3, providing support and shock absorption, replacing the traditional pneumatic tire 3. It eliminates the need for gas pressure to support the wheel, avoiding the risk of vehicle loss of control due to tire blowouts at high speeds. Even if the elastic element 4 is partially damaged, the remaining portion can still provide basic support, preventing the complete failure of a traditional pneumatic tire after a blowout, thus improving vehicle driving safety. Furthermore, the support element 5, embedded within the elastic element 4, forms a cooperative support structure with the elastic element 4, allowing for adjustment of wheel stiffness by modifying the structure of the support element 5.

[0026] In some embodiments, the elastic element 4 includes a rubber component. It is understood that the elastic element 4, made of rubber, possesses excellent elasticity and wear resistance, can absorb vibrations transmitted from the ground through deformation, and can adapt to long-term repeated loads. Exemplarily, the assembled elastic element 4, tire 3, support 5, and rim 1 are placed in a vulcanizing mold, and a preset temperature and pressure are applied. During this process, the rubber material of the tire 3 and the elastic element 4 undergoes a cross-linking reaction, transforming from a linear polymer structure to a three-dimensional network structure. Simultaneously, the rubber material forms a chemical bond with the metal surfaces of the rim 1 and support 5, resulting in an integrally molded structure of the elastic element 4, tire 3, support 5, and rim 1. Compared to traditional mechanical connections, the connection strength of the elastic element 4, tire 3, support 5, and rim 1 is higher, the sealing performance is better, and it can withstand long-term repeated load impacts, effectively improving the durability and load-bearing capacity of the wheel.

[0027] In some embodiments, the elastic member 4 includes a plurality of polygonal structures 40, which are uniformly distributed along the outer periphery of the rim 1. Each polygonal structure 40 has a hollow structure 41. Exemplarily, the polygonal structure 40 can be a triangle, rectangle, pentagon, hexagon, etc., and this embodiment does not specifically limit its shape. (Refer to...) Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the overall structure of the elastic element 4 provided in an exemplary embodiment of this application. Figure 8 yes Figure 7The enlarged view of section C shows that polygonal structure 40 is a hexagonal structure. Adjacent hexagonal structures are connected by vulcanization, which ensures a more stable connection between adjacent polygonal structures 40, better distributes the load, improves the structural stability of elastic element 4, and prevents excessive deformation of elastic element 4 under load. (Refer to...) Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the wheel structure provided in another exemplary embodiment of this application. Figure 6 yes Figure 5 The BB cross-sectional view shows that multiple hexagonal structures are evenly distributed along the circumference of the rim 1, which ensures balanced radial force on the wheel, avoids premature component damage caused by local stress concentration, and extends the wheel's service life. In addition, the polygonal structure 40 has a hollow structure 41 design, which can reduce the overall weight of the elastic element 4 while ensuring the support strength of the elastic element 4, thereby reducing vehicle energy consumption and preventing the wheel inertia from increasing due to excessive weight of the elastic element 4.

[0028] In some embodiments, the support member 5 comprises spring steel. It is understood that spring steel possesses high strength, a high elastic limit, and good fatigue properties. The high elastic limit of spring steel indicates that the support member 5 can reduce the occurrence of permanent deformation when subjected to repeated loads, thereby avoiding problems such as stiffness reduction due to deformation failure of the support member 5, excessive deformation of the elastic element 4, and abnormal wear of the tire 3. This provides stable rigid support for the wheel, significantly reducing the frequency and cost of wheel maintenance and improving user convenience. Spring steel can be processed into different shapes using conventional processes such as cold bending and hot forging, facilitating stiffness adjustment through structural modifications.

[0029] In some embodiments, refer to Figure 9 , Figure 9 This is a schematic diagram of the overall structure of the multiple support members 5 provided in an exemplary embodiment of this application. The wheel includes multiple support members 5, which are evenly distributed along the outer periphery of the rim 1. The even distribution of the multiple support members 5 ensures that the radial force on the wheel is balanced, avoids component damage caused by local stress concentration, and ensures the consistency of the wheel's stiffness in different directions.

[0030] In some embodiments, refer to Figure 9 and Figure 10 , Figure 10This is a schematic diagram of the structure of the support member 5 provided in an exemplary embodiment of this application. The support member 5 includes a first connecting part 50 and a second connecting part 51 connected to each other. The second connecting parts 51 are disposed at both ends of the first connecting part 50. The two second connecting parts 51 are disposed opposite each other and their axial projections along the rim 1 coincide. The second connecting parts 51 extend radially along the rim 1. By adjusting the shape and size of the first connecting part 50 and the second connecting part 51, the lateral stiffness of the first connecting part 50 can be adjusted, and the vertical stiffness of the second connecting part 51 can be adjusted. This configuration allows for more precise stiffness adjustment and avoids mutual interference when adjusting stiffness in different directions. The driving scenarios of vehicles are complex. Therefore, by adjusting the shape and size of the first connecting part 50 and the second connecting part 51, the differentiated requirements of different wheel stiffness can be matched, improving the versatility of the wheels.

[0031] In some embodiments, the support member 5 includes a third connecting portion 52, which is disposed between the two second connecting portions 51 and connected to the first connecting portion 50. It is understood that the third connecting portion 52 extends radially along the rim 1, thereby enabling it to bear and transmit the vertical load of the wheel, achieving adjustment of the vertical stiffness; see reference... Figure 9 and Figure 10 Two second connecting portions 51 and one third connecting portion 52 are distributed at intervals along the axial direction of the rim 1, ensuring that each second connecting portion 51 and third connecting portion 52 can be embedded into the inner hollow area of ​​the elastic member 4 and form an effective fit with the inner wall of the elastic member 4. The specific number and size of the second connecting portions 51 and the third connecting portions 52 can be adapted according to the axial dimension and vertical stiffness requirements of the wheel, and this application embodiment does not specifically limit this.

[0032] In some embodiments, the first connecting portion 50 extends in a direction inclined to the axial direction of the rim 1. Specifically, the first connecting portion 50 is connected to the ends of two opposing second connecting portions 51, thereby forming a "Z"-shaped structure. With this configuration, the two opposing second connecting portions 51 are respectively embedded in the radially inner and outer regions of the elastic member 4. When the elastic member 4 is subjected to load and tends to collapse inward or bulge outward, the second connecting portions 51 can provide a reverse support force to limit its excessive radial deformation. The inclined first connecting portion 50 extends in a combined axial and radial direction of the rim 1, and the surface of the first connecting portion 50 is in close contact with the inner wall of the elastic member 4. This configuration can increase the contact area between the support member 5 and the elastic member 4, thereby improving the rigid support for the elastic member 4.

[0033] In some embodiments, refer to Figure 11 , Figure 12 and Figure 13 , Figure 11 This is a schematic diagram of the overall structure of the rim 1 and spokes 2 provided in an exemplary embodiment of this application. Figure 12This is a schematic diagram of the structure of the spoke 2 provided in an exemplary embodiment of this application. Figure 13 This is a schematic diagram of the structure of the rim 1 provided in an exemplary embodiment of this application. The spokes 2 have a first mounting hole 20, and the rim 1 has a second mounting hole 12 corresponding to the first mounting hole 20. The wheel includes a fastener 6, which passes through the first mounting hole 20 and the second mounting hole 12 and is threadedly connected to at least one of the first mounting hole 20 and the second mounting hole 12. The spokes 2 and the rim 1 are connected by the fastener 6. The spokes 2 and the rim 1 are detachably fastened together by the fastener 6. Exemplarily, the first mounting holes 20 are evenly distributed along the circumference of the spokes 2, and the number of the first mounting holes 20 is the same as the number of the second mounting holes 12 on the rim 1. The fastener 6 is a bolt. The first mounting holes 20 and the second mounting holes 12 are used for the fastener 6 to pass through, so as to achieve the threaded fastening of the spokes 2 and the rim 1. The first mounting hole 20 can be a threaded through hole, and the second mounting hole 12 can be a fastening threaded hole. The bolt tightly fixes the spokes 2 and the rim 1 through the threaded engagement, which facilitates after-sales disassembly and maintenance, thereby reducing maintenance difficulty and cost.

[0034] In some embodiments, one of the spokes 2 and the rim 1 is provided with a locating pin 21, and the other of the spokes 2 and the rim 1 is provided with a locating groove 13, the locating pin 21 being embedded in the locating groove 13. (Refer to...) Figure 12 A locating pin 21 is provided on the side of the spoke 2 facing the rim 1, as shown in the reference. Figure 13 The rim 1 has a positioning groove 13 on the side facing the spoke 2, and a positioning pin 21 is embedded in the positioning groove 13. The positioning pin 21 can be a circular protrusion pin set on the side of the spoke 2 facing the rim 1. The cooperation between the positioning pin 21 and the positioning groove 13 can realize the positioning of the spoke 2 and the rim 1 during installation, and at the same time enhance the overall structural strength after the spoke 2 and the rim 1 are connected. This setting can improve the ease of installation of the spoke 2 and the rim 1 and improve the installation efficiency.

[0035] In some embodiments, refer to Figure 14 , Figure 14This is a schematic diagram of the structure of a wheel rim 1 provided in another exemplary embodiment of this application. The wheel rim 1 includes a body portion 10 and extension portions 11. The extension portions 11 are disposed on both sides of the body portion 10 along the axial direction of the wheel rim 1. The tire 3 is disposed between two adjacent extension portions 11 and is connected to the extension portions 11 and the body portion 10 respectively. The body portion 10 has an annular structure, and the extension portions 11 are annular protrusions extending outward from both sides of the body portion 10 along the axial direction, together forming the main frame of the wheel rim 1. Its main function is to provide an installation base for the tire 3, the elastic element 4, and the support element 5. The tire 3 is disposed between the two extension portions 11 and is connected to the extension portions 11 and the body portion 10 through a vulcanization process. The extension portions 11 can both limit the axial movement of the tire 3 and increase the connection area between the tire 3 and the wheel rim 1. Through the vulcanization process, the tire 3, the elastic element 4, the support element 5, and the wheel rim 1 form an integrally molded structure. It is understandable that the extension 11 can limit and fix the tire 3, prevent the tire 3 from shifting axially during driving, and provide a larger contact area for the connection between the tire 3 and the rim 1, thereby increasing the bonding strength between the rubber and the metal and improving the reliability of the connection.

[0036] According to a second aspect of this application, a vehicle is provided, including the aforementioned wheel. The wheel includes a rim 1, spokes 2, a tire 3, an elastic element 4, and a support element 5; the spokes 2 are disposed at one axial end of the rim 1 and connected to the rim 1; the tire 3 is disposed on the outer periphery of the rim 1 and connected to the rim 1, and the tire 3 has a receiving cavity 30; the elastic element 4 is filled within the receiving cavity 30, and the support element 5 is embedded within the elastic element 4, the support element 5 being used to improve the stiffness of the elastic element 4. With this configuration, the elastic element 4 fills the receiving cavity 30 of the tire 3 to provide support and shock absorption, replacing the traditional pneumatic tire 3, eliminating the need to rely on gas pressure for wheel load bearing, avoiding the risk of vehicle loss of control due to tire blowouts during high-speed driving, and improving vehicle driving safety; furthermore, the support element 5 is embedded within the elastic element 4, forming a cooperative support structure with the elastic element 4, and the wheel stiffness can be adjusted by adjusting the structure of the support element 5.

[0037] In some embodiments, the vehicle includes a chassis, a power system, and the aforementioned wheels. The wheels are connected to the chassis, and the power system drives the wheels to rotate. It is understood that the wheels can be connected to the chassis via a suspension system. The vehicle provided in this embodiment can be a gasoline-powered vehicle or a new energy vehicle, etc., and this application does not specifically limit its type. Taking a new energy vehicle as an example, it can be a pure electric vehicle, a series hybrid electric vehicle, a parallel hybrid electric vehicle, or a series-parallel hybrid electric vehicle; this application embodiment does not specifically limit its type.
