[0040] In a fourth aspect, an embodiment of the present invention provides a vehicle, comprising the wheel provided by the embodiment of the third aspect.

[0041] The technical solution of the above invention has the following advantages or beneficial effects:

[0042] The hub cover provided by the embodiment of the present invention can be used as a visual substitute for the wheel hub after being installed on the wheel of the vehicle, whether the vehicle is in a driving state or a stopped state. Since the mechanical connection part of the hub cover has a structural deformation related to the state of the sub-cover body connected to it in the radial direction of the wheel, the mechanical connection part can drive the sub-cover body connected to it to move radially along the wheel and constrain the stroke of the sub-cover body in the process of overcoming the structural deformation. Since the structural deformation of the mechanical connection part and the process of overcoming the structural deformation are both mechanically driven, that is, the sub-cover body can move radially along the wheel under the mechanical drive of the mechanical connection part, so that the user can select the position of the edge of the sub-cover body relative to the wheel according to the needs. For example, the user can select the edge of the sub-cover body of the hub cover to be as close to the outer edge of the tire as possible, and meet the user's needs for the appearance of the wheel when the wheel hub structure remains unchanged. The sub-cover body can visually meet the user's needs for a wider rim to make up for the defect that the wheel hub cannot provide a wider rim.

[0043] In addition, the design of the sub-cover body that can move along the radial direction of the wheel provided in the embodiment of the present invention allows the size of the sub-cover body to be designed according to user needs. Even if the edge of the sub-cover body can extend to the side of the tire, when the tire passes through an obstacle and is squeezed, the mechanical connection part can undergo structural deformation in the radial direction of the wheel, causing the sub-cover body to shrink along the radial direction of the wheel toward the hub axle. After leaving the obstacle, the mechanical connection part overcomes its structural deformation and drives the sub-cover body to extend along the radial direction of the wheel toward the tire, thereby avoiding the sub-cover body from being damaged, thereby effectively improving the service life of the hub cover.

DETAILED DESCRIPTION

[0054] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0055] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0056] In addition, the terms "first", "second", etc. included in the embodiments of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific number or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing objects with the same attributes when describing them in the embodiments of the present invention.

[0057] The vehicle involved in the embodiment of the present invention may be a hybrid vehicle using an engine as a power source, using an engine and an electric motor as power sources, or an electric vehicle using an electric motor as a power source.

[0058] The side surface of any structure on the wheel involved in the embodiments of the present invention generally refers to the side of the structure facing the outside of the vehicle after the wheel is installed on the vehicle. For example, the side surface of the wheel hub refers to the side of the wheel hub facing the outside of the vehicle after the wheel to which the wheel hub belongs is installed on the vehicle. For another example, the side surface of the wheel refers to the side of the wheel facing the outside of the vehicle after the wheel is installed on the vehicle.

[0059] Figure 1 The structural schematic diagram of the wheel hub side of a vehicle in the prior art is given as an example. Figure 1 As shown, in the prior art, the wheel hub 21 has a wheel hub axle 211, a wheel rim 212, and a plurality of wheel spokes 213 disposed between the wheel hub axle 211 and the wheel rim 212. In the prior art, in order to pursue the beauty of the wheel, the user hopes that the side width D of the wheel rim 212 is as wide as possible to reduce the area exposed by the tire. However, when the vehicle is running, once encountering an obstacle, the overly wide wheel rim 212 is easily damaged, resulting in damage to the entire wheel hub, which has an adverse effect on the driving safety of the vehicle.

[0060] In order to solve the contradiction between the wheel appearance pursued by users and the need to limit the side width of the rim in the prior art, the embodiment of the present invention provides a hub cover 10. While ensuring that the rim 212 has a high safety, the hub cover 10 can meet the user's demand for the side width of the rim 212 in terms of appearance and vision.

[0061] in, Figure 2 A structural schematic diagram showing the relative relationship between the hub cover, tire and wheel hub of a wheel provided by an embodiment of the present invention; Figures 3 to 6 The embodiment of the present invention provides Figure 2 Schematic diagrams of different structures of the partial cross-section of the wheel cut by the cutting line l shown; Figure 7 A schematic diagram of the side structure of a wheel hub provided by an embodiment of the present invention is shown.

[0062] like Figures 2 to 6 As shown, the hub cover 10 provided in the embodiment of the present invention may include: a plurality of sub-cover bodies 11 and a mechanical connection portion 12 disposed on the back of each sub-cover body 11, wherein:

[0063] A plurality of sub-cover bodies 11 are arranged along the circumference of the wheel 20, and there is a movable space between every two adjacent sub-cover bodies 11;

[0064] The mechanical connection part 12 on the back of each sub-cover body 11 is connected to the wheel hub 21 of the wheel 20, so that the sub-cover body 11 is movably connected to the wheel hub 21;

[0065] In the radial direction of the wheel 20, the mechanical connection portion 12 has structural deformation related to the state of the sub-cover body 11 to which it is connected;

[0066] The mechanical connection part 12 is used to drive the connected sub-cover body 11 to move along the radial direction of the wheel 20 based on structural deformation, and to restrict the travel of the sub-cover body 11.

[0067] The mechanical connection portion 12 is connected to the spokes of the hub 21 .

[0068] There is a movable space between each two adjacent sub-cover bodies 11. Figure 2 As shown, there is a gap of a certain size between the adjacent edges of two adjacent sub-cover bodies 11. The existence of the gap enables the sub-cover bodies 11 to move in the radial direction of the wheel.

[0069] In addition, there may be a movable space between each two adjacent sub-cover bodies 11, and there may be at least a partially overlapping area between each two adjacent sub-cover bodies 11, and there may be a gap between the overlapping areas between the two adjacent sub-cover bodies 11, so that the movement of each sub-cover body 11 in the radial direction of the wheel does not interfere with each other.

[0070] Among them, Figure 2 As shown, the side of the sub-cover body involved in the embodiment of the present invention is generally designed as a fan-shaped structure. Based on the fan-shaped structure design of the side of the sub-cover body, even if there is a movable space between adjacent sub-cover bodies, visually, the side of the multiple sub-cover bodies and the area on the wheel hub that is not covered by the sub-cover bodies can still be combined into a complete visual side, that is, for the wheel with the hub cover installed, the user still sees a complete side structure from the side of the wheel, so as to meet the user's demand for the appearance of the wheel.

[0071] Among them, the active connection between the sub-cover body 11 and the wheel hub 21 generally means that, through the above-mentioned mechanical connection part 12, there is a connection relationship between the sub-cover body 11 and the wheel hub 21, and based on this connection relationship, the sub-cover body 11 can move in the radial direction of the wheel hub 21 and within a limited stroke range (move toward the axial direction of the wheel hub 21 or move toward the tire direction).

[0072] Among them, the state of the sub-cover body 11 generally refers to the position of the sub-cover body 11 on the side of the wheel 20, or the displacement of the position of the sub-cover body 11 on the side of the wheel 20 relative to the reference position (the reference position is the position of the sub-cover body 11 on the side of the wheel 20 when the vehicle is in a stationary state), etc.

[0073] There is a dynamic balance between the structural deformation of the mechanical connection part 12 and the position of the sub-cover body 11 connected thereto, that is, when the position of the sub-cover body 11 changes, the structural deformation will also change in linkage. After the structural deformation and the change in the position of the sub-cover body 11 break the dynamic balance, the structural deformation will tend to return to the state of dynamic balance, that is, in the process of returning to the dynamic balance, the mechanical connection part 12 drives the sub-cover body 11 to return to the position corresponding to the dynamic balance. Therefore, even if the mechanical connection part 12 breaks the structural deformation due to obstacles, the centrifugal force of the wheel after the vehicle starts, etc., the mechanical connection part 12 can also restore the position of the sub-cover body 11 on the side of the wheel, and the position of the sub-cover body 11 on the side of the wheel can be kept basically unchanged regardless of whether the vehicle is in a stopped state or a driving state.

[0074] Among them, the elastic deformation parameters of the mechanical connection part 12 required for the above-mentioned dynamic equilibrium state, the size and model of the selected elastic deformation structure, and the gravity of the sub-cover body 11 and the centrifugal force generated by the wheels during the driving process of the vehicle are all related. This relationship can be obtained through simulation experiments. The present application does not limit the elastic deformation parameters, the size and model of the selected elastic deformation structure, etc.

[0075] Any scheme similar to the principle given in the present application (i.e., after the dynamic balance between the structural deformation of the mechanical connection part 12 and the position of the sub-cover body 11 is broken, the mechanical connection part 12 will return to the dynamic balance, and this recovery process will restore the sub-cover body 11 whose position has changed to its original state) is within the protection scope of the present application.

[0076] For example, when the tire of a wheel passes over an obstacle, the force applied to the sub-cover body 11 by the obstacle has a component in the radial direction of the wheel 20 toward the axis of the hub 21, causing the mechanical connection part 12 to undergo structural deformation, driving the sub-cover body 11 to move toward the axis of the hub 21, thereby breaking the dynamic balance between the structural deformation of the mechanical connection part 12 and the sub-cover body 11. Once the obstacle disappears, the structural deformation of the mechanical connection part 12 recovers to the original dynamic balance state, causing the sub-cover body 11 to return to its original position, thereby preventing the sub-cover body 11 from being damaged and ensuring that the sub-cover body 11 recovers to its original state, thereby ensuring the overall consistency and aesthetics of the appearance of the hub cover.

[0077] Since the sub-cover body 11 can move along the radial direction of the wheel 20, it can shrink when encountering an obstacle, and restore to its original state after the obstacle disappears, and will not be damaged by the obstacle, so that the sub-cover body 11 can extend to the side of the tire, such as Figure 2As shown, in the case where the rim of the wheel hub 21 has a relatively small real radius r, after the wheel hub cover 10 provided by the embodiment of the present invention is installed, the edge positions of the various sub-cover bodies 11 included in the wheel hub cover 10 will affect the rim radius observed by the user, that is, the wheel with the various sub-cover bodies 11 installed makes the user observe a rim visual radius R obtained based on the edge of the sub-cover body 11, and the rim visual radius R meets the user's requirements for the appearance of the wheel.

[0078] Therefore, among the multiple sub-covers included in the hub cover provided by the embodiment of the present invention, no matter whether the vehicle is in a driving state or a stopped state, after the hub cover is installed on the wheel of the vehicle, it can be visually used as a substitute for the wheel hub. Since the mechanical connection part of the hub cover has a structural deformation related to the state of the sub-covers connected to it in the radial direction of the wheel, the mechanical connection part can drive the sub-covers connected to it to move in the radial direction of the wheel and constrain the stroke of the sub-covers in the process of overcoming the structural deformation. Since the structural deformation of the mechanical connection part and the process of overcoming the structural deformation are both mechanically driven, that is, the sub-covers can move in the radial direction of the wheel under the mechanical drive of the mechanical connection part, so that the user can choose the position of the edge of the sub-cover relative to the wheel according to the needs. For example, the user can choose the edge of the sub-cover of the hub cover to be as close to the outer edge of the tire as possible, and meet the user's needs for the appearance of the wheel when the wheel hub structure remains unchanged. The sub-cover can visually meet the user's needs for a wider rim to make up for the defect that the wheel hub cannot provide a wider rim.

[0079] In addition, the design of the sub-cover body that can move along the radial direction of the wheel provided in the embodiment of the present invention allows the size of the sub-cover body to be designed according to user needs. Even if the edge of the sub-cover body can extend to the side of the tire, when the tire passes through an obstacle and is squeezed, the mechanical connection part can undergo structural deformation in the radial direction of the wheel, causing the sub-cover body to shrink along the radial direction of the wheel toward the hub axle. After leaving the obstacle, the mechanical connection part overcomes its structural deformation and drives the sub-cover body to extend along the radial direction of the wheel toward the tire, thereby avoiding the sub-cover body from being damaged, thereby effectively improving the service life of the hub cover.

[0080] In addition, the sub-cover body 11 of the hub cover provided in the embodiment of the present invention covers the tire, which can achieve the purpose of protecting the tire and prevent the side of the tire from being scratched by obstacles such as curbs.

[0081] In addition, since each sub-cover 11 is relatively independent, each sub-cover 11 can be replaced according to demand, reducing the maintenance cost of the hub cover. Moreover, the user can personalize the color, decoration, etc. of each sub-cover 11 to meet the needs of different users for the appearance of the hub cover.

[0082] Specifically, in order to realize the connection between the mechanical connection part 12 and the wheel hub 21, and at the same time, through the connection between the mechanical connection part 12 and the wheel hub 21, the sub-cover body 11 is firmly fixed on the side of the wheel, in the embodiment of the present invention, Figures 2 to 6 As shown, the mechanical connection part 12 provided in the embodiment of the present invention may include: a positioning sliding structure 121 and an elastic deformation structure 122, wherein the positioning sliding structure 121 is fixed to the back side of the sub-cover body 11; the positioning sliding structure 121 is embedded in the wheel hub 21, slidingly connected to the wheel hub 21, and positions the sub-cover body 11 in the axial direction of the wheel 20; the elastic deformation structure 122 is respectively connected to the positioning sliding structure 121 and the wheel hub 21; in the radial direction of the wheel 20, the elastic deformation structure 122 has a structural deformation related to the state of the sub-cover body 11 connected thereto; the elastic deformation structure 122 is used to drive the positioning sliding structure 121 to move radially along the wheel 20 based on the structural deformation; when the positioning sliding structure 121 moves radially along the wheel 20, it drives the sub-cover body 11 connected thereto to move.

[0083] The positioning sliding structure 121 cooperates with a groove or a slide rail provided on the wheel hub 21 so that the main surface of the sub-cover body 11 fits with the side surface of the wheel 20 .

[0084] Among them, the above-mentioned positioning sliding structure 121 can be a slider or a support rod, etc. Regardless of whether it is a slider or a support rod, after it is assembled on the spokes of the wheel hub 21, there is a limiting structure for the slider or the support rod on the spokes, such as a slide groove, a slide rail, etc. The limiting structure can position the slider or the support rod in the axial direction of the wheel hub 21 so that the slider or the support rod will not move in the axial direction of the wheel hub 21, thereby positioning the sub-cover body 11 in the axial direction of the wheel 20 to prevent the sub-cover body 11 from shaking.

[0085] The elastic deformation structure 122 may be a spring, an elastic body, a damping structure, etc. In order to clearly illustrate the relative positional relationship between the elastic deformation structure 122 and the positioning sliding structure 121 provided in the embodiment of the present invention, the elastic deformation structure 122 provided in the embodiment of the present invention is described below by taking an elastic deformation structure including a spring as an example.

[0086] Specifically, the elastic deformation structure 122 provided in the embodiment of the present invention may have three structures. Figure 3 As shown, the first structure of the elastic deformation structure 122 is a first elastic component, wherein one end of the first elastic component is fixedly connected to the positioning sliding structure 121 , and the other end is fixedly connected to the wheel hub 21 .

[0087] That is, the first elastic component, such as a spring component, is directly fixedly connected to the positioning sliding structure 121 and the wheel hub 21, such as by riveting or screwing. This structure is simple and low in cost.

[0088] For the first structure of the mechanical connection part 12, the positioning sliding structure 121 connected thereto can be a sliding block or a sliding bracket. Figure 3 The combination of the sliding bracket and the first elastic component into the mechanical connection part 12 is given as an example. It is worth noting that the groove for assembling the slider or the sliding bracket provided on the wheel hub can be provided with a structure for limiting the slider or the sliding bracket, for example, a lip edge for blocking the slider can be provided on the edge of the groove to ensure that the positioning sliding structure 121 can be firmly fixed in the wheel hub, and prevent the positioning sliding structure 121 from moving in the axial direction, so as to achieve the purpose of stabilizing the sub-cover body. It can be understood that the slide rail matched with the positioning sliding structure 121 provided on the wheel hub 21 is generally a guide rail provided along the radial direction on the spokes of the wheel hub 21, and accordingly, the positioning sliding structure 121 can be provided with a groove matched with the guide rail, so that the groove slides along the guide rail. Among them, the positioning sliding structure 121 is assembled on the groove matched with the positioning sliding structure 121 provided on the wheel hub 21, and the above-mentioned first elastic component can also be accommodated in the groove, so that the back of the sub-cover body 11 fits as closely as possible with the side of the wheel hub 21, and ensures that the sub-cover body 11 can be relatively firmly installed on the side of the wheel hub 21.

[0089] Among them, Figure 4 As shown, the second structure of the elastic deformation structure 122 includes: a second elastic component 1221 and a fixing member 1222, wherein one end of the second elastic component 1221 is fixedly connected to the positioning sliding structure 121, and the other end is fixedly connected to the fixing member 1222; the fixing member 1222 is engaged or fixedly assembled in a specific mounting position on the wheel hub 21 that matches the fixing member 1222, wherein the specific mounting position is close to the hub shaft of the wheel hub 21.

[0090] like Figure 4 As shown, the fixing connector 2141 of the wheel hub is provided with a structure for assembling the fixing member 1222, which is a specific installation position on the wheel hub 21 that matches the fixing member 1222. The structure of the specific installation position may be a snap-fitting groove that matches the fixing member 1222, so as to fix the fixing member 1222 by snap-fitting, thereby realizing the integrated assembly of the second elastic component 1221 and the fixing member 1222 onto the wheel hub.

[0091] With respect to the second structure of the elastic deformation structure 122 , the second elastic component 1221 and the fixing member 1222 may be an integrally formed structure to facilitate assembly.

[0092] With respect to the second structure of the mechanical connection portion 12 , the second elastic component 1221 is assembled in a groove provided on the wheel hub 21 , so that the sub-cover body 11 can be well fitted with the side of the wheel hub 21 to ensure the stability of the sub-cover body 11 .

[0093] Among them, Figure 5 As shown, the third structure of the elastic deformation structure 122 includes: a third elastic component 1223 and a fourth elastic component 1224 respectively arranged on both sides of the positioning sliding structure 121, wherein one end of the third elastic component 1223 and one end of the fourth elastic component 1224 are respectively fixedly connected to the positioning sliding structure 121; the other end of the third elastic component 1223 and the other end of the fourth elastic component 1224 are respectively fixed on the wheel hub 21, wherein the fixed position of the third elastic component 1223 on the wheel hub 21 is close to the edge of the wheel hub 21, and the fixed position of the fourth elastic component 1225 on the wheel hub 21 is close to the axis of the wheel hub 21.

[0094] Among them, Figure 5 As shown, for the third structure of the elastic deformation structure 122, the third elastic component 1223 and the fourth elastic component 1224 disposed on both sides of the positioning sliding structure 121 are assembled together with the positioning sliding structure 121 in the groove disposed on the wheel hub 21. The sub-cover body 11 can be well fitted with the side of the wheel hub 21 to ensure the stability of the sub-cover body 11.

[0095] The third elastic component 1223 and the fourth elastic component 1224 extend or contract along the radial direction of the hub 21 .

[0096] In addition, with respect to the third structure of the elastic deformation structure 122, two elastic components (a third elastic component 1223 and a fourth elastic component 1224) are respectively arranged on both sides of the positioning sliding structure 121. When the positioning sliding structure 121 moves along the radial direction of the wheel, the two elastic components generate forces in the same direction on the positioning sliding structure 121 (for example, when the positioning sliding structure 121 moves in the radial direction of the wheel toward the axis of the wheel, the third elastic component 1223 generates a pulling force on the positioning sliding structure 121 in the opposite direction to the moving direction of the positioning sliding structure 121, and the fourth elastic component 1224 generates a pulling force on the positioning sliding structure 121 in the opposite direction to the moving direction of the positioning sliding structure 121). 24 generates a thrust on the positioning sliding structure 121 in the opposite direction to the moving direction of the positioning sliding structure 121; for example, in the process of the positioning sliding structure 121 moving in the radial direction of the wheel toward the edge of the wheel, the third elastic component 1223 generates a thrust on the positioning sliding structure 121 in the opposite direction to the moving direction of the positioning sliding structure 121, and the fourth elastic component 1224 generates a pulling force on the positioning sliding structure 121 in the opposite direction to the moving direction of the positioning sliding structure 121), so as to more stably control the movement of the sub-cover body 11, and reduce the influence of the movement inertia generated during the movement of the sub-cover body 11 on the sub-cover body 11.

[0097] Furthermore, if Figure 7As shown, a mounting hole 2143 is provided at one end close to the wheel hub shaft, and the mounting hole 2143 is connected to the limiting guide structure 2142 for assembling the positioning sliding structure 121, so that the positioning sliding structure 121 can enter the limiting guide structure 2142 through the mounting hole 2143, which facilitates the installation and removal of the positioning sliding structure 121. And after the elastic deformation structure 122 is subsequently assembled to the wheel hub, the elastic deformation structure 122 can prevent the positioning sliding structure 121 from sliding to the position of the mounting hole 2143, ensuring that the sub-cover body 11 is stably installed on the side of the wheel.

[0098] Furthermore, based on the above Figure 5 Take the elastic deformation structure 122 as an example, Figure 6 As shown, the hub cover 10 provided in the embodiment of the present invention further includes: a damping structure 123 disposed between the positioning sliding structure 121 and the elastic deformation structure 122, wherein one end of the damping structure 123 is fixedly connected to the positioning sliding structure 121, and the other end is fixedly connected to the elastic deformation structure 122. By providing the damping structure 123, a buffering effect can be played on the structural deformation and inertia of the elastic deformation structure 122, and the impact or inertial impact caused by the excessive structural deformation force of the elastic deformation structure 122 can be avoided to damage the edge area where the wheel hub is connected to the elastic deformation structure 122, or the rim and the hub shaft close to the edge area.

[0099] In addition, a buffer pad can be set in the edge area of ​​the wheel hub connected to the elastic deformation structure 122 to buffer the impact or inertial impact caused by excessive structural deformation of the elastic deformation structure 122, thereby extending the service life of various components of the wheel and reducing the noise generated during impact.

[0100] In addition, the outer diameter of the hub cover 10 of the embodiment of the present invention is larger than the outer diameter of the wheel hub 21. That is, the outer diameter of the multiple sub-cover bodies 11 of the hub cover 10 arranged circumferentially is larger than the outer diameter of the wheel hub 21. Figure 2 As shown, the outer diameter of the hub cover 10 generally refers to the distance R from the axis of the hub to the edge of the hub 21. This is to meet the user's demand for the side visual width of the rim of the hub 21, so as to improve the beauty of the side of the wheel.

[0101] It is worth noting that when the vehicle is in a driving state, the sub-cover body 11 provided in the embodiment of the present invention maintains its diameter under the combined action of the centrifugal force generated by the wheel driving and the structural deformation of the connected elastic deformation structure 122. After the vehicle stops, the sub-cover body 11 maintains its diameter under the structural deformation of the elastic deformation structure 122. There is a difference between the structural deformation of the elastic deformation structure 122 when the vehicle is in a driving state and the structural deformation of the elastic deformation structure 122 when the vehicle stops. The existence of this difference enables the outer diameter of the circumferentially arranged multiple sub-cover bodies 11 to remain consistent when the vehicle is in a driving state and when the vehicle stops.

[0102] Further, for each sub-cover body 11 of the hub cover 10 provided in the embodiment of the present invention, when the tire 23 of the wheel 20 is squeezed by an obstacle, the sub-cover body 11 moves along the radial direction of the wheel hub 21 toward the axis of the wheel hub 21 to prevent the obstacle from damaging the sub-cover body 11. When the tire 23 of the wheel 20 recovers from the state of being squeezed by the obstacle to the normal state, the sub-cover body 11 moves along the radial direction of the wheel hub 21 toward the tire 23 of the wheel 20 to restore the sub-cover body 11 to the original state, ensuring that the appearance of the hub cover 10 can remain consistent.

[0103] Furthermore, if Figure 7 As shown, an embodiment of the present invention provides a wheel hub 21, which is used to assemble the wheel hub cover 10 provided by any of the above embodiments. The wheel hub 21 may include: a wheel hub shaft 211, a wheel rim 212, a plurality of wheel spokes 213 disposed between the wheel hub shaft 211 and the wheel rim 212, and an assembly portion 214 disposed on the wheel spokes 213, wherein:

[0104] The mounting portion 214 is connected to the mechanical connection portion 12 of the hub cover 10 .

[0105] Based on the structure of the wheel hub 21 , the wheel hub cover 10 provided in the above embodiment can be movably connected to the wheel hub 21 to ensure that each sub-cover body 11 of the wheel hub cover 10 can move in the radial direction of the wheel hub 21 after being squeezed, thereby avoiding damage to the sub-cover body 11 .

[0106] Furthermore, if Figures 3 to 6 As shown, the assembly portion 214 includes a fixed connection member 2141 and a limiting guide structure 2142 arranged along the extension direction of the spoke 213, wherein:

[0107] The fixed connection member 2141 is fixedly connected to the mechanical connection portion 12 of the hub cover 10;

[0108] The limiting guide structure 2142 is used to limit and guide the mechanical connection portion 12 of the hub cover 10, so that the sub-cover body 11 of the hub cover 10 corresponding to the mechanical connection portion 12 moves along the radial direction of the wheel hub 21;

[0109] The limiting guide structure 2142 cooperates with the assembled mechanical connection part 12 to restrict the travel of the sub-cover body 11 .

[0110] The fixed connector 2141 may be fixed on the wheel hub, and may be assembled with the mechanical connection portion 12 via riveted or screwed rivets or threaded holes, screws, etc.

[0111] Among them, the limiting guide structure 2142 can be Figures 3 to 6 The groove with the limiting lip shown may also be a guide rail that cooperates with the positioning sliding structure 121 (such as a sliding block) of the mechanical connection portion 12 of the hub cover 11 .

[0112] By cooperating with the fixing connector 2141 and the limiting guide structure 2142 arranged along the extension direction of the spoke 213, the sub-cover bodies 11 of the hub cover 10 can be fixed and the movement of the sub-cover bodies 11 can be guided so that the movement of the sub-cover bodies 11 is controllable.

[0113] Furthermore, if Figure 7 As shown, the above-mentioned assembly part 214 may also include: a mounting hole 2143, wherein the mounting hole 2143 is connected to the limiting guide structure 2142, so that the positioning sliding structure 121 of the mechanical connection part 12 enters the limiting guide structure 2142 from the mounting hole 2143, so that the elastic deformation structure 122 blocks the mounting hole 2143, and the elastic deformation structure 122 limits the positioning sliding structure 121 from moving in the limiting guide structure 2142.

[0114] Furthermore, if Figure 2 As shown, an embodiment of the present invention provides a wheel, which may include the wheel hub 21 provided in the above embodiment and the wheel hub cover 10 provided in any of the above embodiments.

[0115] It is worth noting that after the hub cover 10 is assembled to the wheel, the side of the hub shaft 211 may also be assembled with an existing small hub cover mounted on the hub shaft.

[0116] Furthermore, an embodiment of the present invention provides a vehicle, which may include the wheel provided by the above embodiment.

[0117] For the above-mentioned wheel or the vehicle having the above-mentioned wheel, no matter the vehicle is in a driving state or a stopped state, after the hub cover provided in the above-mentioned embodiment is installed on the wheel of the vehicle,

[0118] It can be used as a visual substitute for the wheel hub. Since the mechanical connection part of the hub cover has structural deformation related to the state of the sub-cover body connected to it in the radial direction of the wheel, the mechanical connection part can drive the sub-cover body connected to it to move radially along the wheel and constrain the travel of the sub-cover body in the process of overcoming the structural deformation. Since the structural deformation of the mechanical connection part and the process of overcoming the structural deformation are both mechanically driven, that is, the sub-cover body can move radially along the wheel under the mechanical drive of the mechanical connection part, so that the user can choose the position of the sub-cover body edge relative to the wheel according to the needs. For example, the user can choose the edge of the sub-cover body of the hub cover to be as close to the outer edge of the tire as possible, and meet the user's needs for the appearance of the wheel when the hub structure remains unchanged. The sub-cover body can visually meet the user's needs for a wider rim to make up for the defect that the wheel hub cannot provide a wider rim.

[0119] In addition, the design of the sub-cover body that can move along the radial direction of the wheel provided in the embodiment of the present invention allows the size of the sub-cover body to be designed according to user needs. Even if the edge of the sub-cover body can extend to the side of the tire, when the tire passes through an obstacle and is squeezed, the mechanical connection part can undergo structural deformation in the radial direction of the wheel, causing the sub-cover body to shrink along the radial direction of the wheel toward the hub axle. After leaving the obstacle, the mechanical connection part overcomes its structural deformation and drives the sub-cover body to extend along the radial direction of the wheel toward the tire, thereby avoiding the sub-cover body from being damaged, thereby effectively improving the service life of the hub cover.

[0120] In addition, since the multiple sub-cover bodies included in the wheel hub cover can extend to the side of the tire, it has a certain protective effect on the side of the tire and prevents the side of the tire from being scratched.

[0121] Below Figure 8 The tire 20 with the hub cover 10 provided by the embodiment of the present invention installed is shown along the Figure 8 Taking the process of the wheel rotating in the clockwise direction K passing the obstacle OB as an example, the changes of the sub-cover body 11 of the hub cover 10 in the process of the wheel passing the obstacle OB are described in detail.

[0122] Specifically, Figure 8 As shown, during the driving process of the vehicle, the wheel 20 rotates clockwise K and presses against the obstacle OB, which causes the tire to deform. Accordingly, the sub-cover body 11 (for example, Figure 8 The marked A) is also squeezed, causing the elastic deformation structure 122 to deform toward the wheel hub axis, driving the sub-cover body 11 to move in the radial direction of the wheel toward the axis of the wheel 20. The other sub-cover bodies 11 are in a balanced state with the elastic deformation structure 122 and can remain in the same position on the side of the wheel. Figure 8 The position of the marker B in the image contacts the obstacle. Figure 8 The marked A is no longer squeezed by the obstacle, so A recovers to the equilibrium state from the current structural deformation due to the elastic deformation structure 122 to which it is connected, so that the corresponding sub-cover body 11 recovers to the initial state, and the sub-cover body 11 corresponding to B moves in the radial direction of the wheel toward the axial direction of the wheel 20. After the wheel leaves the obstacle, each sub-cover body 11 of each hub cover 10 recovers to the initial state.
