[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for use in the description of the embodiments. Obviously, the drawings described are only part of the embodiments of the present invention, not all of the embodiments, and those skilled in the art can also obtain other design solutions and drawings based on these drawings without creative work.

[0026] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0027] The non-pneumatic tire generally uses an elastic support body 6 structure to replace the air pressure in the traditional pneumatic tire to provide the required support force for the vehicle. The connection method between the rim 5 and the support body 6 is crucial, which determines whether the non-pneumatic tire can give full play to its advantages of explosion-proof tire, no air pressure maintenance, and high safety performance.

[0028] When dealing with the installation problem of non-pneumatic tires, the current state of the art usually requires changes to the entire structure of the hub and rim 5, which makes it impossible to directly apply such tires to existing automobile hubs. In other words, if non-pneumatic tires are to be used, the cost of hub production must be borne additionally because existing hubs are not compatible. This poor adaptability makes it difficult for non-pneumatic tires to be used in motor hub products, such as electric vehicles and scooters, because these products require specially designed hubs to ensure performance and safety.

[0029] To this end, the present invention provides a mounting plate for connecting the rim 5 and the support body 6, referring to Figure 1 to Figure 5 , which includes a connecting disk, which is a circular ring structure composed of multiple fan-shaped connecting members 1 fastened to each other, the inner wall of the fan-shaped connecting member 1 is used to connect with the rim 5, and the outer wall of the fan-shaped connecting member 1 is used to connect with the support body 6, and the first connecting part 3 and the second connecting part 4 are respectively provided at both ends of the fan-shaped connecting member 1, and the first connecting part 3 and the second connecting part 4 on each adjacent two fan-shaped connecting members 1 are fixedly connected, and the fan-shaped connecting member 1 is provided with a plurality of protrusions 101, and the protrusions 101 are arranged in a circle on both side surfaces of the fan-shaped connecting member 1.

[0030] A plurality of fan-shaped connectors 1 form a mounting plate body, the inner wall of the mounting plate is connected to the outer wall of the rim 5, the mounting plate is interference mounted on the rim 5, the outer wall of the mounting plate is connected to the inner wall of the support body 6 of the non-pneumatic tire, and by adding intermediate conversion accessories, the purpose of tight fitting on the existing wheel hub can be achieved through circumferential interference fitting internally, and an open bonding surface is added externally, which can be used in conjunction with the mechanical connection or hot vulcanization bonding technology commonly used for non-pneumatic tires. By providing protrusions on both side surfaces of the fan-shaped connector 1 and arranging these protrusions in a circular pattern, the contact area and tightness between the rim 5 and the mounting plate can be significantly improved, which helps to improve the load-bearing capacity and durability of the tire.

[0031] If the connection part cannot be tightly closed, the safety performance of the entire structure may be reduced, or even a safety accident may occur. Figure 4The first connection part 3 is provided with a first bolt hole 301 penetrating the thickness direction of the first connection part 3, and the second connection part 4 is provided with a second bolt hole penetrating the thickness direction of the second connection part 4, and the first bolt hole 301 and the second bolt hole are arranged opposite to each other. Through the circumferential bolt installation, the first connection part 3 and the second connection part 4 are effectively pulled together tightly, which enhances the stability of the connection and reduces the risk of loosening due to vibration or external force. This structural design simplifies the installation process and improves the installation efficiency.

[0032] When installing by circumferential bolts, these bolts may conflict with certain parts of the rim 5, which may hinder the correct combination of the rim 5 and the mounting plate, thereby affecting the installation efficiency and safety of the entire rim 5 system. Figure 5 The first connection part 3 is provided with a connection block, the second connection part 4 is provided with a connection groove that is engaged with the connection block, the connection block is provided with a third bolt hole 302, the second connection part 4 is provided with a threaded hole, and the third bolt hole 302 and the threaded hole are arranged opposite to each other. The first connection part 3 and the second connection part 4 are engaged by radial bolt installation. This engagement method not only improves the stability of the connection, but also enhances the durability and reliability of the entire structure, so that various operation requirements can be better met in practical applications.

[0033] Preferably, refer to Figure 3 If the bolt installation position conflicts with the spoke position on the support body 6, a notch 117 needs to be provided on the support body 6 to avoid the conflict.

[0034] The support body 6 may slip off from the circumferential direction of the mounting plate. Therefore, in one embodiment, a plurality of limit blocks 103 are provided on the outer wall of the fan-shaped connector 1. During the mechanical clamping process between the outer wall of the mounting plate and the inner wall of the support body 6, the limit blocks 103 can effectively limit the slipping of the support body 6 in the circumferential direction, thereby ensuring the stability and reliability of the entire installation process. In addition, the presence of the limit blocks 103 can also play a role in assisting the positioning installation, further improving the accuracy and convenience of the installation.

[0035] The support body 6 can be connected to the mounting plate by mechanical clamping. Therefore, in one embodiment, the two end surfaces of the fan-shaped connector 1 are provided with a plurality of mounting holes 102, the support body 6 is provided with a baffle, the baffle is provided with a fourth bolt hole matching the mounting hole 102, and the mounting plate is fixedly connected to the support body 6 by bolts. When the outer wall of the mounting plate needs to be mechanically clamped with the inner wall of the support body 6, the mounting plate and the support body 6 can be firmly fixed together by bolts through the mounting holes 102 and the fourth bolt holes, thereby enhancing the structural strength and durability of the entire device.

[0036] The support body 6 can be connected to the mounting plate by injection molding. Figure 2 The outer wall of the fan-shaped connector 1 is provided with a plurality of grooves 104, and the grooves 104 are used to fill the connection liquid, and the mounting plate and the support body 6 are chemically bonded. During the process of injection molding bonding between the outer wall of the mounting plate and the inner wall of the support body 6, the grooves 104 can increase the bonding contact area, thereby improving the bonding firmness and the stability of the overall structure.

[0037] In the tire manufacturing process, the material is a key factor to ensure the overall performance and safety of the tire. Therefore, in one embodiment, the fan-shaped connector 1 is made of elastomer, plastic, metal or composite material. The elastomer, plastic, metal or composite material has high hardness and high wear resistance, and can show excellent durability and wear resistance in various harsh working environments.

[0038] Preferably, the fan-shaped connector 1 may be made of elastomeric materials such as rubber, cast polyurethane (CPU), thermoplastic elastomer (TPU), epoxy resin, or plastic materials such as PET, PP, PVC, ABS, PC, PA, or composite materials and metal materials.

[0039] Preferably, the fan-shaped connecting member 1 may be made of a single material or a combination of two or more materials.

[0040] The weight of the tire is a key factor that is directly related to the overall performance of the tire and the driver's experience during use. Figure 3 , the inner wall of the fan-shaped connecting member 1 is provided with a slot 105. The cost of tire materials can be effectively reduced, and the performance of the tire can be further improved by reducing the weight of the mounting plate. Reducing weight means that while maintaining the strength and durability of the tire, the non-suspension weight of the vehicle can be reduced, thereby improving the acceleration performance and braking efficiency of the vehicle, and also improving the fuel economy of the vehicle. In addition, reducing the weight of the tire also helps to reduce the rolling resistance of the vehicle, thereby reducing the wear of the tire during driving and extending the service life of the tire.

[0041] Preferably, the slots may be radial slots or circumferential slots, and the radial slots may be used as process holes for injection molding production.

[0042] Preferably, the fan-shaped connecting member 1 is a hollow structure to reduce material costs and reduce the weight of the mounting plate.

[0043] A non-pneumatic tire, characterized in that it comprises a mounting plate as described in any one of the above items, as well as a tread, a rim 5 and a support body 6, wherein the mounting plate is arranged between the support body 6 and the rim 5.

[0044] By introducing the mounting plate, the non-pneumatic tire can be mounted on the existing rim 5. The mounting process is simplified, and the cost and time of replacing the tire are greatly reduced. Without the need for complicated modification of the existing rim 5, the many benefits of the non-pneumatic tire can be enjoyed, such as reducing the risk of tire blowout, reducing maintenance costs, and improving driving safety.

[0045] In one embodiment, in the process of converting a standard rim 5 into a non-pneumatic tire, first, a circumferentially detachable mounting plate composed of two fan-shaped connectors 1 is prepared, and the fan-shaped connectors 1 are connected by bolts to form a mounting plate body; the assembled mounting plate is installed on the rim 5 with circumferential interference fit to ensure that the interference force is sufficient to meet the needs of the tire when driving and prevent the tire from slipping during use; the outer surface of the mounting plate is designed with a connecting surface that matches the inner surface of the non-pneumatic tire support body 6, and the connection method can be mechanical clamping or injection molding bonding. For the mechanical clamping structure, a mounting hole 102 of a circumferential locking structure is set on the end face of the fan-shaped connector 1, and a limit block 103 is set on the outer circumferential surface to ensure stability; for the injection molding bonding structure, a groove 104 is set on the outer circumferential surface of the mounting plate to increase the bonding area, thereby improving the bonding firmness.

[0046] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
