Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular to a non-pneumatic tire with adjustable stiffness and a vehicle. Background Art

[0002] The spokes of the common spoke-type non-pneumatic tires are usually made by casting or injection molding. This manufacturing method makes the spokes and the inner and outer rings of the tire an integral whole and cannot be separated. During the design and manufacturing process, if the stiffness characteristics of the tire need to be adjusted, the traditional approach is to achieve this by changing the number, size or material of the spokes during the tire molding stage.

[0003] However, once the tire is formed, the stiffness is fixed and cannot be adjusted. This non-adjustable stiffness greatly limits the application scope and diversified development of non-pneumatic tires, and also increases design limitations. Summary of the invention

[0004] The embodiments of the present application provide a non-pneumatic tire and a vehicle with adjustable stiffness, which can change the stiffness of the spoke structure by adjusting the number and / or size of the inserts.

[0005] In a first aspect, an embodiment of the present application provides a non-pneumatic tire with adjustable stiffness. The non-pneumatic tire includes a spoke structure, a plurality of embedded parts, and a fixing assembly.

[0006] The spoke structure includes a plurality of spoke units, with a gap between two adjacent spoke units; an insert can be filled into the gap; a fixing component is connected to the insert, and the fixing component can maintain the insert in a state of filling the gap; wherein, after inserts of different numbers and / or different sizes are filled into corresponding gaps, the stiffness of the spoke structure can be adjusted and changed.

[0007] The spoke structure is composed of a plurality of spoke units, and there are certain gaps between these spoke units. The coordination of the plurality of spoke units can ensure stability and durability when under pressure.

[0008] The inserts can be inserted into the gaps in the spoke structure. The inserts can be designed in different quantities and sizes to allow for flexible adjustment and optimization based on specific needs. By selecting different materials and shapes, the inserts can effectively change the stiffness characteristics of the spoke structure to meet the needs of various application scenarios.

[0009] The function of the fixing assembly is to firmly fix the insert in the gap of the spoke structure. The fixing assembly can be designed to be strong enough to withstand the various forces and stresses generated during the vehicle's driving. At the same time, the fixing assembly should also be easy for users to remove and replace the insert in order to adjust the stiffness.

[0010] In some examples, at least one receiving surface is provided on the insert, and the receiving surface can receive the spoke unit, and the deformation range of the spoke unit can be changed by abutting against the receiving surface during the deformation process of the spoke unit under force.

[0011] At least one receiving surface is designed and configured on the insert. The receiving surface is used to effectively receive and support the spoke unit. When the spoke unit is deformed by external force, the spoke unit can change and adjust the deformation range of the spoke unit by contacting and abutting with the corresponding receiving surface. By setting such a receiving surface, the deformation behavior of the spoke unit can be effectively controlled and changed.

[0012] Different inserts can have different positions and different numbers of bearing surfaces according to specific design needs and functional requirements. This design diversity enables the insert to flexibly adjust and optimize the deformation range of the spoke unit according to different actual application scenarios. By increasing or decreasing the number of bearing surfaces, or adjusting the position of the bearing surfaces, fine control of the deformation behavior of the spoke unit can be achieved.

[0013] When the deformation range of the spoke unit changes, the stiffness of the entire spoke structure will also change accordingly. This is because the deformation behavior of the spoke unit directly affects the overall mechanical properties of the spoke structure. By adjusting the deformation range of the spoke unit, the stiffness of the spoke structure can be adjusted to meet different usage needs and performance requirements. The flexibility and adjustability of this design make the spoke structure more adaptable and reliable in practical applications.

[0014] In some examples, the voids are honeycomb voids, and the shape of the insert is adapted to the shape of the honeycomb voids.

[0015] The voids in the spoke structure may present a honeycomb structure (or a cavity structure similar to a honeycomb, not limited to a honeycomb structure, such as other prismatic cavities), and the shape of the insert is adapted to or completely matches the shape of the honeycomb voids, and they can be embedded together. In this way, the insert can effectively adjust and change the elastic deformation range of the spoke units that form the honeycomb voids.

[0016] When the spoke unit is subjected to external force, its deformation degree can be properly controlled, so that the support strength of the spoke unit can be correspondingly improved. This design not only improves the overall stability of the structure, but also optimizes the efficiency of material use to a certain extent, making the entire structure perform better when bearing loads.

[0017] In some examples, the gap is an "S"-shaped gap formed by the cooperation of two "S"-shaped spoke units, the insert is a semi-cylindrical structure, the insert abuts against the inner ring of the spoke structure, or the insert abuts against the outer ring of the spoke structure, or the insert is suspended and fixed between the inner ring and the outer ring through a fixing component;

[0018] The deformed area of ​​the spoke unit during the deformation process can abut against the embedded part, thereby improving the stiffness of the spoke unit.

[0019] The gap in the spoke structure can be an "S"-shaped gap formed by the cooperation of two adjacent "S"-shaped spoke units. In this design, the insert can be a semi-cylindrical strip structure, and the insert can be in close contact with the inner ring of the spoke structure, or the insert can be in close contact with the outer ring of the spoke structure. In addition, the insert can be suspended and fixed between the inner ring and the outer ring by a fixing component. Such a design makes the insert play an important role in the spoke structure.

[0020] During the deformation of the spoke unit, the corresponding deformation area can contact the insert, thereby effectively improving the stiffness of the spoke unit. This design not only enhances the overall stability of the spoke structure, but also effectively disperses and withstands forces from different directions, thereby improving the bearing capacity and durability of the spoke structure. Through this design, the spoke structure maintains lightweight while also having high strength and stiffness, meeting the needs of high-performance applications.

[0021] In some examples, the insert includes a combination of one or more materials of the styrene type, thermoplastic polyurethane, polyester type, polyamide type;

[0022] Alternatively, the insert is a combination of one or more materials selected from the group consisting of plastic, metal, and wood.

[0023] Inserts can be made of a combination of different materials or a single material. These materials include, but are not limited to, styrenics, thermoplastic polyurethanes, polyesters, and polyamides. These materials can be used alone or in combination to meet specific application needs and performance requirements.

[0024] In addition, the insert can also be made of other types of materials, such as plastic, metal or wood. These materials can also be used alone or in combination according to specific application scenarios and functional requirements.

[0025] In some examples, the fixing assembly includes a fixing ring and a plurality of fixing members. The fixing ring is disposed on one side of the spoke structure. The fixing ring is provided with a plurality of fixing holes. The fixing members can be passed through the fixing holes and fixedly connected to the embedded member.

[0026] The fixing assembly includes a fixing ring and a plurality of fixings. The fixing ring is arranged on one side of the spoke structure to fix and support the entire structure. A plurality of fixing holes are evenly distributed on the fixing ring, and these holes are designed to accommodate the fixings. The fixings can pass through these fixing holes and can be fixedly connected with the embedded parts. This design ensures a firm connection between the embedded parts and the spoke structure, thereby improving the stability and reliability of the overall structure. In this way, the fixing assembly can not only effectively fix the embedded parts, but also withstand forces from different directions, ensuring the stability and safety of the entire spoke structure during use.

[0027] In some examples, two fixing rings are provided, and the two fixing rings are respectively provided on both sides of the spoke structure, and the embedded component is provided between the two fixing rings, and the fixing component is adapted to the embedded component.

[0028] Two fixing rings can be provided. The two fixing rings can be placed on both sides of the spoke structure respectively. In this configuration, the insert is arranged between the two fixing rings. In order to ensure the stability and reliability of the overall structure, the fixings and the inserts can be the same in number and correspond one to one, or one insert can be fixed simultaneously by multiple fixings to provide stability of the insert connection. The above-mentioned adaptation method not only ensures the stability of the insert between the fixing rings, but also improves the bearing capacity and durability of the overall structure. The inserts can be designed in different quantities and sizes so as to be flexibly adjusted and optimized according to specific needs. By selecting different materials and shapes, the inserts can effectively change the stiffness characteristics of the spoke structure, thereby meeting the needs of various application scenarios.

[0029] In some examples, two or more fixing rings are connected to one end of the insert.

[0030] One end of the insert may be connected to two or more fixing rings. Through this design, the two or more fixing rings can provide higher connection stability, thereby making the connection of the corresponding insert more stable and reliable. This design not only enhances the fixing effect of the insert, but also improves the stability of the overall structure, ensuring the safety and durability of the insert in practical applications.

[0031] In some examples, the fastener includes at least one of a bolt, a screw, a rivet, a pin, and a snap.

[0032] The fixings of the present application may include various connecting elements, such as bolts, screws, rivets, pins, and buckles, etc. The number and types of these fixings are not strictly limited to the above-mentioned ones, but can be flexibly selected and combined according to actual application needs and design requirements.

[0033] In a second aspect, an embodiment of the present application provides a vehicle, comprising a non-pneumatic tire with adjustable stiffness and a vehicle body as described above, wherein the non-pneumatic tire is mounted on the vehicle body.

[0034] A vehicle with the above-mentioned non-pneumatic tire can change the stiffness of the spoke structure by adjusting the number and / or size of the inserts. Specifically, the inserts can be embedded in the gaps in the spoke structure, and the inserts can be designed in different numbers and sizes so as to be flexibly adjusted and optimized according to specific needs. By selecting different materials and shapes, the inserts can effectively change the stiffness characteristics of the spoke structure to meet the needs of various application scenarios. The fixing assembly can firmly fix the inserts in the gaps of the spoke structure. The fixing assembly can be designed to be strong enough to withstand the various forces and stresses generated during the driving of the vehicle. At the same time, the fixing assembly should also be easy for the user to disassemble and replace the inserts in order to adjust the stiffness. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] To solve the above technical problems, please refer to Figure 1-Figure 3 As shown, the first aspect of the present application provides a non-pneumatic tire with adjustable stiffness, which can change the stiffness of the spoke structure 100 by adjusting the number and / or size of the inserts 200 .

[0043] Reference Figure 1-Figure 3 As shown, in some examples, the present application provides a non-pneumatic tire with adjustable stiffness. The non-pneumatic tire includes a spoke structure 100 , a plurality of inserts 200 , and a fixing assembly 300 .

[0044] The spoke structure 100 includes a plurality of spoke units 110, and there is a gap between two adjacent spoke units 110; the insert 200 can be filled into the gap; the fixing component 300 is connected to the insert 200, and the fixing component 300 can maintain the insert 200 in a state of filling the gap; wherein, after inserts 200 of different numbers and / or different sizes are filled into the corresponding gaps, the stiffness of the spoke structure 100 can be adjusted and changed.

[0045] In some specific examples, the present application proposes a non-pneumatic tire with adjustable stiffness, the design and structure of which can meet different usage scenarios and requirements. The non-pneumatic tire mainly includes three core components: a spoke structure 100, a plurality of inserts 200, and a fixing assembly 300.

[0046] The spoke structure 100 is composed of a plurality of spoke units 110, and there are certain gaps between the spoke units 110. The coordinated arrangement of the plurality of spoke units 110 can ensure stability and durability when subjected to pressure.

[0047] The insert 200 can be inserted into the gap in the spoke structure 100. The insert 200 can be designed in different quantities and sizes so as to be flexibly adjusted and optimized according to specific needs. By selecting different materials and shapes, the insert 200 can effectively change the stiffness characteristics of the spoke structure 100, thereby meeting the needs of various application scenarios.

[0048] The function of the fixing assembly 300 is to firmly fix the insert 200 in the gap of the spoke structure 100. The fixing assembly 300 can be designed to be strong enough to withstand various forces and stresses generated during the vehicle's driving. At the same time, the fixing assembly 300 should also be easy for the user to remove and replace the insert 200 to adjust the stiffness.

[0049] The non-pneumatic tire of the present application has several significant advantages. First, by disassembling and assembling the inserts 200 at different positions, the user can easily adjust the sinking amount of the non-pneumatic vehicle to adapt to different load requirements. Second, by replacing the inserts 200 of different numbers and sizes, the three-dimensional stiffness of the non-pneumatic vehicle can be finely adjusted, thereby improving the handling and stability of the vehicle. In addition, the integrated spoke structure 100 of the present application not only simplifies the manufacturing process of the tire, but also expands its functionality, enabling it to better adapt to various road conditions and usage environments.

[0050] The non-pneumatic tire of the present application increases the user's participation and fun. The user can adjust the position and number of the inserts 200 according to his or her own preferences and needs to achieve a personalized tire stiffness setting. This "Do It Yourself" (DIY) method can not only improve user satisfaction, but also extend the service life of the tire and reduce maintenance costs. In short, the non-pneumatic tire of the present application not only provides high performance, but also brings more fun and convenience.

[0051] The tire force-bearing mode can be set to two bottom load-bearing modes and a top load-bearing mode. Traditional pneumatic tires and solid tires are both bottom load-bearing modes, that is, the load is transferred to the ground through the sidewall or the bottom elastomer; the tire force-bearing principle of the top load-bearing mode is that the tire tread has a support ring, the spokes are flexible, and the flexible spokes are circumferentially distributed in the support ring. The load is suspended on the support ring through the flexible spokes distributed on the top, and the flexible spokes at the bottom only play a role of easy bending and deformation, and do not play a major supporting force role.

[0052] Specifically, the non-pneumatic tire in the present application can be a top-bearing tire, and the corresponding tread has a rigid inlay in the tread. During driving, the load of the tire is mainly borne by the rigid inlay in the tread. The non-pneumatic tire also includes spokes, which include spokes with traction capabilities, referred to as traction units. When the tire is under pressure, the traction unit at the relatively upper side will be stretched and generate a tensile force, and the traction unit at the relatively lower side will be compressed. Since the spoke itself does not have a supporting force, the force on the wheel hub will be transmitted to the upper side of the rigid inlay in the tread through the upper traction unit, and the rigidity of the rigid inlay in the tread will then transmit the force to the position below the rigid inlay in the tread that contacts the ground.

[0053] Reference Figure 1-Figure 3As shown, in some examples, at least one receiving surface is provided on the insert 200, and the receiving surface can receive the spoke unit 110. During the deformation process of the spoke unit 110 under force, the deformation range of the spoke unit 110 can be changed by abutting against the receiving surface. The provision of the receiving surface can change the deformation range of the spoke unit 110. Different inserts 200 can have receiving surfaces at different positions and different numbers, thereby adjusting more deformation ranges of the spoke unit 110. After the deformation range of the spoke unit 110 is changed, the stiffness of the entire spoke structure 100 will change accordingly.

[0054] At least one receiving surface is designed and configured on the insert 200. The receiving surface is used to effectively receive and support the spoke unit 110. When the spoke unit 110 is deformed by an external force, the spoke unit 110 can change and adjust the deformation range of the spoke unit 110 by contacting and abutting against the corresponding receiving surface. By setting such a receiving surface, the deformation behavior of the spoke unit 110 can be effectively controlled and changed.

[0055] Different inserts 200 may have different positions and different numbers of receiving surfaces according to specific design requirements and functional requirements. This design diversity enables the insert 200 to flexibly adjust and optimize the deformation range of the spoke unit 110 according to different actual application scenarios. By increasing or decreasing the number of receiving surfaces, or adjusting the position of the receiving surfaces, fine control of the deformation behavior of the spoke unit 110 can be achieved.

[0056] When the deformation range of the spoke unit 110 changes, the stiffness of the entire spoke structure 100 will also change accordingly. This is because the deformation behavior of the spoke unit 110 directly affects the overall mechanical properties of the spoke structure 100. By adjusting the deformation range of the spoke unit 110, the stiffness of the spoke structure 100 can be adjusted to meet different usage needs and performance requirements. The flexibility and adjustability of this design make the spoke structure 100 more adaptable and reliable in practical applications.

[0057] In some examples, the void is a honeycomb void, and the shape of the insert 200 matches the shape of the honeycomb void. The insert 200 can change the elastic deformation range of the spoke unit 110 corresponding to the honeycomb void, and can change the support strength of the spoke unit 110.

[0058] The voids in the spoke structure 100 may present a honeycomb structure (or a cavity structure similar to a honeycomb, not limited to a honeycomb structure, such as other prismatic cavities), and the shape of the insert 200 is adapted to or completely matches the shape of the honeycomb voids, and they can be embedded together. In this way, the insert 200 can effectively adjust and change the elastic deformation range of the spoke units 110 that form the honeycomb voids.

[0059] When the spoke unit 110 is subjected to external force, its deformation degree can be properly controlled, so that the support strength of the spoke unit 110 is correspondingly improved. This design not only improves the overall stability of the structure, but also optimizes the use efficiency of materials to a certain extent, so that the entire structure performs better when bearing loads.

[0060] Reference Figure 1-Figure 3 As shown, in some examples, the gap is an "S"-shaped gap formed by the cooperation of two "S"-shaped spoke units 110, the insert 200 is a semi-cylindrical structure, the insert 200 abuts against the inner ring 120 of the spoke structure 100, or the insert 200 abuts against the outer ring 130 of the spoke structure 100, or the insert 200 is suspended and fixed between the inner ring 120 and the outer ring 130 through the fixing assembly 300;

[0061] The deformed area of ​​the spoke unit 110 during the deformation process can abut against the insert 200 , thereby increasing the rigidity of the spoke unit 110 .

[0062] The gap in the spoke structure 100 may be an "S"-shaped gap formed by the cooperation of two adjacent "S"-shaped spoke units 110. In this design, the insert 200 may be a semi-cylindrical strip structure, and the insert 200 may be in close contact with the inner ring 120 of the spoke structure 100, or the insert 200 may be in close contact with the outer ring 130 of the spoke structure 100. In addition, the insert 200 may be suspended and fixed between the inner ring 120 and the outer ring 130 by the fixing assembly 300. Such a design enables the insert 200 to play an important role in the spoke structure 100.

[0063] During the deformation of the spoke unit 110, the corresponding deformation area can contact the insert 200, thereby effectively improving the stiffness of the spoke unit 110. This design not only enhances the overall stability of the spoke structure 100, but also effectively disperses and withstands forces from different directions, thereby improving the bearing capacity and durability of the spoke structure 100. Through this design, the spoke structure 100 has high strength and stiffness while maintaining lightness, meeting the requirements of high-performance applications.

[0064] In some examples, the insert 200 includes a combination of one or more materials of the styrene type, thermoplastic polyurethane, polyester type, polyamide type;

[0065] Alternatively, the insert 200 is a combination of one or more materials selected from the group consisting of plastic, metal, and wood.

[0066] The insert 200 can be made of a combination of various materials or a single material. These materials include, but are not limited to, styrene materials, thermoplastic polyurethane, polyester materials, and polyamide materials. These materials can be used alone or mixed and combined as needed to meet specific application needs and performance requirements.

[0067] In addition, the insert 200 may also be made of other types of materials, such as plastic, metal or wood. These materials may also be used alone or in combination according to specific application scenarios and functional requirements.

[0068] Reference Figure 1-Figure 3 As shown, in some examples, the fixing assembly 300 includes a fixing ring 310 and a plurality of fixing members 320 . The fixing ring 310 is disposed on one side of the spoke structure 100 . The fixing ring 310 is provided with a plurality of fixing holes. The fixing members 320 can be passed through the fixing holes and fixedly connected to the embedment 200 .

[0069] The fixing assembly 300 includes a fixing ring 310 and a plurality of fixing members 320. The fixing ring 310 is disposed on one side of the spoke structure 100 to facilitate fixing and supporting the entire structure. A plurality of fixing holes are evenly distributed on the fixing ring 310, and these holes are designed to accommodate the fixing members 320. The fixing members 320 can pass through these fixing holes and can be fixedly connected to the insert 200. This design ensures a firm connection between the insert 200 and the spoke structure 100, thereby improving the stability and reliability of the overall structure. In this way, the fixing assembly 300 can not only effectively fix the insert 200, but also withstand forces from different directions, thereby ensuring the stability and safety of the entire spoke structure 100 during use.

[0070] In some examples, two fixing rings 310 are provided. The two fixing rings 310 are respectively provided on both sides of the spoke structure 100 , the insert 200 is provided between the two fixing rings 310 , and the fixing member 320 is adapted to the insert 200 .

[0071] In some specific embodiments, two fixing rings 310 may be provided. The two fixing rings 310 may be respectively arranged on both sides of the spoke structure 100. In this configuration, the insert 200 is arranged between the two fixing rings 310. In order to ensure the stability and reliability of the overall structure, the fixing members 320 and the insert 200 may be the same in number and correspond one to one, or one insert 200 may be fixed simultaneously by multiple fixing members 320 to provide stability of the connection of the insert 200. The above-mentioned adaptation method not only ensures the stability of the insert 200 between the fixing rings 310, but also improves the bearing capacity and durability of the overall structure. The insert 200 may be designed in different quantities and sizes so as to be flexibly adjusted and optimized according to specific needs. By selecting different materials and shapes, the insert 200 can effectively change the stiffness characteristics of the spoke structure 100, thereby meeting the needs of various application scenarios.

[0072] In some examples, two or more fixing rings 310 are connected to one end of the insert 200. The two or more fixing rings 310 can have a higher connection stability, and can make the connection of the corresponding insert 200 more stable and reliable.

[0076] In a second aspect, an embodiment of the present application provides a vehicle, comprising a non-pneumatic tire with adjustable stiffness and a vehicle body as described above, wherein the non-pneumatic tire is mounted on the vehicle body.

[0077] The vehicle with the above-mentioned non-pneumatic tire can change the stiffness of the spoke structure 100 by adjusting the number and / or size of the inserts 200.
