Description

Technical Field

[0001] This application relates to the field of automotive engineering technology, specifically to a wheel hub cover assembly, a wheel hub assembly, and a vehicle. Background Technology

[0002] With the development of new energy vehicles, aluminum wheel covers (also known as low-drag wheel covers) are gradually being widely used in the automotive parts market, making a considerable contribution to reducing the overall vehicle's wind resistance. To enrich the diverse styling features offered by aluminum wheel covers, a logo cover is often placed in the center of the cover to display the vehicle's brand logo.

[0003] The sign cover is assembled onto the aluminum wheel decorative cover via a snap-fit ​​structure. The aluminum wheel decorative cover is assembled onto the wheel, which is in harsh working conditions. The snap-fit ​​limiting method between the decorative cover and the sign cover in related technologies is relatively simple. After long-term use or repeated disassembly and assembly, the limiting structure will become fatigued, the snap-fit ​​effect will weaken, and the sign cover will easily fall off or cause abnormal noise due to unstable fixation. Utility Model Content

[0004] One objective of this application is to provide a wheel hub decorative cover assembly to solve the problem that the existing logo cover is prone to falling off or causing abnormal noise due to unstable fixing; another objective is to provide a wheel hub assembly; and a third objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] Wheel hub cover assembly, which includes:

[0007] A decorative cover has a mounting hole formed in the middle by a limiting wall. A mounting plate and a positioning block connected to the limiting wall are formed in the mounting hole. A through hole is provided at the connection between the mounting plate and the limiting wall. An elastic claw extending into the through hole is fixed on the mounting plate. A protrusion protruding towards the limiting wall is formed on the elastic claw. A first groove is formed between the positioning block and the limiting wall at the opening of the mounting hole.

[0008] The sign cover includes a body and a retaining plate. The edge of the body is bent inward to form a bent portion. The retaining plate is connected to the bent portion and extends axially. The retaining plate has a retaining hole. The retaining plate is inserted into the through hole and is located between the elastic retaining claw and the limiting wall. The retaining protrusion engages with the retaining hole. The body is fastened to the opening of the mounting hole and the bent portion is engaged in the first groove.

[0009] Through the above technical means, firstly, the locking protrusion on the elastic claw engages with the locking hole on the locking plate to restrict the sign cover from detaching from the decorative cover axially. The sign cover is blocked by the positioning block at the opening of the mounting hole, thus restricting its axial inward movement. In other words, the engagement of the locking protrusion and the latch, and the engagement of the sign cover and the positioning block, together achieve the circumferential positioning and stable limiting of the decorative cover. Secondly, the locking plate of the sign cover is inserted into the through hole and is located between the elastic claw and the limiting wall. The elastic claw and the limiting wall can clamp the locking plate in the radial direction, ensuring good limiting on both sides of the locking plate in the radial direction, improving the radial limiting effect of the sign cover at the locking plate. Thirdly, the engagement of the bent part of the sign cover with the first groove is used to limit the bent part radially, thereby achieving the radial limiting effect of the sign cover at the body. The sign cover and the decorative cover can be securely assembled without relying on additional fasteners, achieving precise limiting in both the axial and radial directions. The structure is compact, easy to install, and highly reliable. This assembly is particularly suitable for aluminum wheel decoration structures that are subject to long-term wind pressure, vibration, and disassembly / reassembly, and has strong fatigue resistance and reliable service life.

[0010] Furthermore, the elastic claw includes a connecting arm and an elastic arm. One end of the connecting arm is fixedly connected to the mounting plate and extends toward the opening side of the mounting hole. The elastic arm is connected to the other end of the connecting arm and extends into the through hole. The locking protrusion is disposed on the side of the elastic arm facing the limiting wall.

[0011] Through the above technical means, this structure not only ensures the effective axial positioning of the mark cover, but also improves the tightness of the latching through the pre-tightening force of the elastic arm, reducing the risk of loosening and abnormal noise during operation. At the same time, the rigid connection between the connecting arm and the mounting plate provides good support, preventing the latch structure from failing under long-term vibration or environmental stress.

[0012] Furthermore, the edge of the main body is sequentially formed with a first folded edge, a second folded edge, and a bent portion. The first folded edge extends outward from the edge of the main body, and the second folded edge extends inward from the first folded edge. The first folded edge, the second folded edge, and the bent portion form a second groove on the inner side of the mark cover. The positioning block has a protrusion. The first groove is formed between the protrusion and the limiting wall, and the second groove is matched and connected to the protrusion.

[0013] Using the above technical means, the three-segment folded edge structure is arranged in an orderly manner, forming a circumferential ring structure on the inner side of the sign cover, i.e., the side closest to the decorative cover. This structure defines a second groove with a specific cross-sectional shape. The positioning block on the decorative cover has a protrusion, which, together with the limiting wall, forms the first groove. When the sign cover is installed on the decorative cover, the second groove formed by its folded edge covers the protrusion of the positioning block, achieving a structural interlocking fit. Through the mutual cooperation between the second groove and the protrusion, the installation of the sign cover on the decorative cover can obtain additional radial and axial limiting effects. This fitting method improves the overall fit of the sign cover in the assembled state, effectively preventing loosening or abnormal noise caused by assembly gaps. On the other hand, it also enhances the structural vibration resistance, allowing the sign cover to maintain a stable installation state even when subjected to high-frequency vibration or external impact. This continuous folded edge structure also improves the overall deformation resistance, especially under high temperature, high humidity, or repeated disassembly and assembly conditions, maintaining a stable shape and structure.

[0014] Furthermore, a first limiting slope is formed on the side of the protrusion facing the first groove, and a second limiting slope is formed on the inner side of the second folded edge to cooperate with the first limiting slope.

[0015] Using the above technical means, when the sign cover is inserted into the mounting hole of the decorative cover from the outside, the second limiting inclined surface can slide along the first limiting inclined surface during the sliding process, realizing an automatic guiding function. This ensures that the sign cover can smoothly enter the mounting position, avoiding jamming, displacement, or misplacement during assembly. Simultaneously, after the sign cover is assembled in place, the first and second limiting inclined surfaces abut against each other, forming a dual limiting effect on the sign cover in both the axial and radial directions. This inclined surface mating structure provides better surface contact compared to a simple vertical limiting edge structure.

[0016] Furthermore, the positioning block is fixedly connected to the limiting wall and the mounting plate, respectively.

[0017] The above technical methods not only improve the stability and deformation resistance of the positioning block itself, but also effectively enhance the overall connection strength between the limiting wall and the mounting plate, preventing structural fatigue, warping, or loosening caused by external impact or long-term use. Furthermore, this multi-faceted interconnected structure allows the positioning block to distribute stress and avoid stress concentration when subjected to the insertion or removal force of the sign cover, thus helping to improve the mechanical properties of the entire decorative cover mounting hole area.

[0018] Furthermore, multiple elastic claws are provided along the circumference of the mounting plate, and the through holes are provided one-to-one with the elastic claws. Multiple card plates are provided along the circumference of the mark cover.

[0019] Through the above technical means, the multi-point cooperation structure of multiple elastic claws and holes significantly improves the firmness of the snap-fit ​​connection, avoids the risk of overall detachment due to single-point snap-fit ​​failure, and enhances the vibration resistance and durability of the sign cover.

[0020] Furthermore, multiple positioning blocks are arranged circumferentially along the mounting holes.

[0021] Through the above technical means, the positioning blocks not only serve as auxiliary positioning structures for snap-fitting, but also provide effective limiting support for the sign cover in the radial and axial directions. The distribution of multiple positioning blocks effectively disperses the force on the mounting holes, improves the overall stability of the structure, and enhances the limiting effect, preventing the sign cover from loosening or shifting during use.

[0022] Furthermore, the positioning blocks and elastic claws are arranged alternately in the circumferential direction.

[0023] Through the above technical means, the staggered arrangement not only optimizes the layout space of the snap-fit ​​components and improves the compactness of the installation structure, avoiding interference between structures, but also ensures uniform stress distribution through this staggered layout method.

[0024] A wheel hub assembly comprising:

[0025] A wheel hub, wherein a plurality of spokes are provided on the wheel hub;

[0026] The wheel hub decorative cover assembly has multiple locking feet on its inner side, which engage with the spokes.

[0027] Through the above technical means, the locking feet engage with the spokes of the wheel hub to achieve reliable positioning and stable fixation of the decorative cover relative to the wheel hub. By setting multiple locking feet to engage with the corresponding spokes, multi-point positioning and fixation between the decorative cover and the wheel hub are achieved, making the installation of the wheel hub decorative cover assembly more convenient and secure, and preventing the decorative cover from loosening or falling off during driving.

[0028] Furthermore, the locking foot includes a fixing block, a neck, and a locking part connected in sequence. The fixing block has a hollow structure. The neck is connected to one side of the fixing block. Multiple support ribs are formed on the opposite side of the fixing block. The support ribs are connected to both the fixing block and the decorative cover.

[0029] Through the above technical means, the support ribs are connected to the fixing block and the decorative cover respectively, which improves the overall bending and torsion resistance of the clamp foot, ensuring that the clamp foot can withstand external loads during use and preventing loosening or breakage caused by vibration or impact.

[0030] Furthermore, a U-shaped groove is formed between the fixing block and the neck, and the locking foot also includes an elastic element disposed in the U-shaped groove. The elastic restoring force of the elastic element causes the locking portion to tend to move away from the fixing block.

[0031] Through the above technical means, the elastic restoring force of the elastic element ensures that the snap-fit ​​part maintains good snap-fit ​​force and stability during the snap-fit ​​process between the decorative cover and the spokes of the wheel hub, preventing loosening caused by vibration or impact, and improving the connection reliability between the wheel hub decorative cover assembly and the wheel hub.

[0032] A vehicle comprising the aforementioned wheel assembly.

[0033] Based on the aforementioned technical means, the wheel assembly achieves a good combination of decorative effect and firmness through a reliable snap-fit ​​structure between the decorative cover and the wheel hub. The multi-dimensional limiting design between the emblem cover and the decorative cover enhances the stability of the emblem cover during use, effectively preventing loosening or detachment caused by vibration, impact, or long-term use, thereby improving the overall appearance integrity and brand recognition of the vehicle.

[0034] The beneficial effects of this application are:

[0035] (1) The protrusion on the elastic claw engages with the hole on the plate to restrict the mark cover from detaching from the decorative cover along the axial direction. The mark cover is blocked by the positioning block at the opening of the mounting hole, thus restricting its movement inward along the axial direction. That is, the engagement of the protrusion and the buckle and the engagement of the mark cover and the positioning block together achieve the positioning and stable limiting of the decorative cover in the circumferential direction.

[0036] (2) The card plate of the sign cover is inserted into the through hole and is located between the elastic claw and the limiting wall. The elastic claw and the limiting wall can clamp the card plate in the radial direction, so that the card plate is well limited on both sides in the radial direction, thereby improving the radial limiting effect of the sign cover at the card plate. The cooperation between the bent part of the sign cover and the first groove is used to limit the bent part in the radial direction, thereby achieving the radial limiting effect of the sign cover at the body.

[0037] (3) The sign cover and the decorative cover can be stably assembled without the need for additional fasteners. Precise positioning is achieved in both the axial and radial directions. The structure is compact, easy to install, and highly reliable. It is suitable for aluminum wheel decoration structures that are subject to long-term wind pressure, vibration and disassembly.

[0052] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0053] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0054] Please see Figure 1-7 As shown, the main structure of the wheel hub decorative cover assembly provided in this application embodiment includes a decorative cover 100 and a marker cover 200, aiming to enhance the stability and fatigue resistance of the marker cover 200 during long-term use through a multi-dimensional limiting structure. Specifically, a mounting hole 111 formed by a limiting wall 110 is formed in the middle of the decorative cover 100. A mounting plate 120 and a positioning block 130 connected to the limiting wall 110 are formed in the mounting hole 111. A through hole 121 is opened at the connection between the mounting plate 120 and the limiting wall 110. An elastic claw 140 extending into the through hole 121 is fixed on the mounting plate 120. A protrusion 141 protruding towards the limiting wall 110 is formed on the elastic claw 140. The positioning block 130 forms a shape between the opening of the mounting hole 111 and the limiting wall 110. The first groove 131 is formed; the sign cover 200 includes a body 210 and a retaining plate 220. The edge of the body 210 is bent inward to form a bent portion 211. The retaining plate 220 is connected to the bent portion 211 and extends axially. The retaining plate 220 has a retaining hole 221. The retaining plate 220 is inserted into the through hole 121 and is located between the elastic retaining claw 140 and the limiting wall 110. The retaining protrusion 141 engages with the retaining hole 221. The body 210 is fastened to the opening of the mounting hole 111 and the bent portion 211 is engaged in the first groove 131. The side of the sign cover 200 used to connect to the decorative cover 100 is defined as the inner side, and the opposite side is the outer side. The outer side of the sign cover 200 is used to set the brand logo. Similarly, the side of the decorative cover 100 used to install on the wheel hub 400 is the inner side, and the side where the sign cover 200 is set is the outer side.

[0055] In the above embodiment, the mounting plate 120 provided in the mounting hole 111 not only enhances the structural strength of the limiting wall 110, but also serves as a bearing structure for the elastic claw 140. When the sign cover 200 is fixed on the decorative cover 100, it can form a multi-dimensional limiting fit. Firstly, the latching protrusion 141 on the elastic claw 140 engages with the latching hole 221 on the latching plate 220 to restrict the sign cover 200 from detaching from the decorative cover 100 axially. The sign cover 200 is blocked by the positioning block 130 at the opening of the mounting hole 111, thereby restricting its axial inward movement. That is, the engagement of the latching protrusion 141 with the latch and the engagement of the sign cover 200 with the positioning block 130 together achieve the positioning and stable limiting of the decorative cover 100 in the circumferential direction. Secondly, the retaining plate 220 of the sign cover 200 is inserted into the through hole 121 and is located between the elastic claw 140 and the limiting wall 110. The elastic claw 140 and the limiting wall 110 can clamp the retaining plate 220 in the radial direction, so that the retaining plate 220 is well limited on both sides in the radial direction, thereby improving the radial limiting effect of the sign cover 200 at the retaining plate 220. Thirdly, the cooperation between the bent portion 211 of the sign cover 200 and the first groove 131 is used to limit the bent portion 211 in the radial direction, thereby achieving the radial limiting effect of the sign cover 200 at the body 210.

[0056] The sign cover 200 and decorative cover 100 can be securely assembled without the need for additional fasteners. Precise positioning is achieved in both the axial and radial directions. The assembly is compact, easy to install, and highly reliable. This assembly is particularly suitable for aluminum wheel trim structures that are subject to long-term wind pressure, vibration, and disassembly / reassembly.

[0057] In some implementations, such as Figure 6 and 7As shown, the elastic claw 140 includes a connecting arm 142 and an elastic arm 143. One end of the connecting arm 142 is fixedly connected to the mounting plate 120 and extends toward the opening side of the mounting hole 111. The elastic arm 143 is connected to the other end of the connecting arm 142 and extends into the through hole 121. The locking protrusion 141 is disposed on the side of the elastic arm 143 facing the limiting wall 110. The elastic claw 140 is arranged in a cantilever manner. The elastic arm 143 is disposed at the distal end of the connecting arm 142, and extends into the through hole 121 after connecting to the connecting arm 142, for cooperating with the inserted sign cover 200 locking plate 220. The elastic arm 143 is a component with a certain elastic recovery capability. Its structure and material design allow it to undergo elastic deformation during the locking process and provide continuous reset pressure after insertion. The position and size of the locking protrusion 141 are designed to cooperate with the locking hole 221 on the sign cover 200 locking plate 220 for insertion. When the sign cover 200 is inserted into the mounting hole 111, the locking plate 220 enters the through hole 121 and pushes the elastic arm 143 to deform. The locking protrusion 141 is temporarily compressed and retracted during the insertion process. When the locking hole 221 moves to the position aligned with the locking protrusion 141, the elastic arm 143 returns to its initial shape, and the locking protrusion 141 automatically springs into the locking hole 221, achieving a firm mechanical locking effect.

[0058] This structure not only ensures the effective axial positioning of the mark cover 200, but also enhances the fit of the latch through the pre-tightening force of the elastic arm 143, reducing the risk of loosening and abnormal noise during operation. Simultaneously, the rigid connection between the connecting arm 142 and the mounting plate 120 provides excellent support, preventing the latch structure from failing under long-term vibration or environmental stress.

[0059] In some implementations, such as Figure 6 and 7 As shown, the edge of the body 210 is sequentially formed with a first folded edge 212, a second folded edge 213, and a bent portion 211. The first folded edge 212 extends outward from the edge of the body 210, and the second folded edge 213 extends inward from the first folded edge 212. The first folded edge 212, the second folded edge 213, and the bent portion 211 form a second groove 214 on the inner side of the mark cover 200. The positioning block 130 has a protrusion 132. The protrusion 132 and the limiting wall 110 form the first groove 131, and the second groove 214 is matched and connected to the protrusion 132.

[0060] In this embodiment, the edge structure of the body 210 of the mark cover 200 has been further optimized. Its edge is sequentially formed with a first folded edge 212, a second folded edge 213, and a bent portion 211 to enhance structural strength and form a multi-limiting fit structure. The first folded edge 212 extends radially outward from the edge of the body 210 to form an outwardly convex structure. The second folded edge 213 extends inward from the end of the first folded edge 212 to form a reverse-covering portion of the overall contour. The bent portion 211 is formed by the continued extension of the second folded edge 213 and extends further in the axial direction to fit with the first groove 131.

[0061] Through the orderly arrangement of the three folded edge structures described above, a ring structure is formed circumferentially on the inner side of the sign cover 200, that is, on the side near the decorative cover 100. This structure defines a second groove 214 with a specific cross-sectional shape. The positioning block 130 on the decorative cover 100 is provided with a protrusion 132, which, together with the limiting wall 110, forms a first groove 131. When the sign cover 200 is installed on the decorative cover 100, the second groove 214 formed by its folded edge exactly covers the protrusion 132 of the positioning block 130, achieving a structural mating fit.

[0062] Through the interaction between the second groove 214 and the protrusion 132, the installation of the sign cover 200 on the decorative cover 100 achieves additional radial and axial limiting effects. This fit improves the overall fit of the sign cover 200 in the assembled state, effectively preventing loosening or abnormal noise caused by assembly gaps. It also enhances the structural vibration resistance, allowing the sign cover 200 to maintain a stable installation even under high-frequency vibration or external impact. This continuous folded edge structure also improves the overall deformation resistance, especially under high temperature, high humidity, or repeated disassembly and assembly conditions, maintaining a stable shape and structure.

[0063] Furthermore, because the edges of the body 210 of the sign cover 200 are successively formed with a first folded edge 212 extending outward and a second folded edge 213 folded inward from the first folded edge 212, the overall structure of the sign cover 200 presents an inwardly concave shape in the center. This concave structure not only helps to enhance the overall rigidity and resistance to external impact of the sign cover 200, but also naturally forms a recessed space in the central area of ​​its body 210. This recessed space is located on the outer surface of the sign cover 200, that is, the side facing the visible side after being assembled to the decorative cover 100. Its concave contour forms a clear boundary with the external structure, providing a good sense of contour and visual focus, and effectively enhancing the three-dimensionality and texture of the appearance. This concave area can be specially designed as a brand logo display area for setting the brand logo of the vehicle or manufacturer. By pasting, embedding, or screen printing the brand pattern in this concave area, it is not only easy to identify the brand, but also effectively avoids wear or scratches caused by the exposed logo.

[0064] In some implementations, such as Figure 6 and 7 As shown, the protrusion 132 has a first limiting slope 133 on the side facing the first groove 131, and the inner side of the second folded edge 213 has a second limiting slope 215 that cooperates with the first limiting slope 133. The first limiting slope 133 extends in an inclined manner, gradually approaching the limiting wall 110 along the direction from the outside to the inside, and is used to guide and limit the assembly direction of the mark cover 200. The inner side of the second folded edge 213 of the mark cover 200 is correspondingly provided with the second limiting slope 215, which extends toward the first limiting slope 133 and forms a slope structure that cooperates with it.

[0065] With the above structural design, when the sign cover 200 is inserted into the mounting hole 111 of the decorative cover 100 from the outside, the second limiting inclined surface 215 can slide along the first limiting inclined surface 133 during the sliding process, realizing an automatic guiding function. This ensures that the sign cover 200 can smoothly enter the mounting position, avoiding jamming, displacement, or accidental insertion during assembly. Simultaneously, after the sign cover 200 is assembled in place, the first limiting inclined surface 133 and the second limiting inclined surface 215 abut against each other, forming a dual limiting effect on the sign cover 200 in both the axial and radial directions. This inclined surface mating structure provides better surface contact compared to a simple vertical limiting edge structure.

[0066] In some implementations, such as Figure 2 , Figure 4 , Figure 6-7As shown, the positioning block 130 is fixedly connected to the limiting wall 110 and the mounting plate 120 respectively. Since the mounting plate 120 is basically perpendicular to the limiting wall 110, the positioning block 130 is set in the junction area between the two, that is, at the corner inside the mounting hole 111, thereby achieving the positioning function while forming a structural reinforcement or reinforced connection.

[0067] By fixing the positioning block 130 to the structural surfaces of the limiting wall 110 and the mounting plate 120 in two different directions, not only is the stability and deformation resistance of the positioning block 130 itself improved, but the overall connection strength between the limiting wall 110 and the mounting plate 120 is also effectively enhanced, preventing structural fatigue, warping, or loosening due to external impact or long-term use. Furthermore, this multi-faceted interconnected structure allows the positioning block 130 to disperse stress and avoid stress concentration when subjected to the insertion or removal force of the sign cover 200, thus helping to improve the mechanical properties of the entire area of ​​the mounting hole 111 of the decorative cover 100.

[0068] In some implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, multiple elastic claws 140 are arranged along the circumference of the mounting plate 120, and the through holes 121 are arranged one-to-one with the elastic claws 140. Multiple clamping plates 220 are arranged along the circumference of the mark cover 200.

[0069] Multiple elastic claws 140 are preferably evenly distributed around the circumference of the mounting plate 120, and each elastic claw 140 is provided with a corresponding through hole 121 to achieve precise engagement between the claw and the hole 221. Correspondingly, the sign cover 200 is also provided with multiple locking plates 220 and locking holes 221 around its circumference. The number of locking holes 221 matches the number of elastic claws 140, ensuring that the sign cover 200 can achieve a stable fixing effect through multi-point locking. The multi-point engagement structure of multiple elastic claws 140 and locking holes 221 significantly improves the firmness of the locking connection, avoids the risk of overall detachment due to single-point locking failure, and improves the vibration resistance and durability of the sign cover 200.

[0070] In some implementations, such as Figure 4 As shown, multiple positioning blocks 130 are arranged circumferentially along the mounting hole 111, and the multiple positioning blocks 130 are preferably evenly distributed in the inner wall area of ​​the mounting hole 111. These positioning blocks 130 not only serve as auxiliary positioning structures for snap-fitting, but also provide effective limiting support for the mark cover 200 in the radial and axial directions. The distribution of multiple positioning blocks 130 effectively disperses the force on the mounting hole 111, improves the overall stability of the structure, and enhances the limiting effect, preventing the mark cover 200 from loosening or shifting during use.

[0071] In some implementations, such as Figure 2 and 4 As shown, the positioning block 130 and the elastic claw 140 are arranged alternately in the circumferential direction, that is, the positioning block 130 and the elastic claw 140 are alternately distributed around the mounting hole 111. This staggered arrangement not only optimizes the layout space of the snap-fit ​​parts and improves the compactness of the installation structure, avoiding interference between structures, but also ensures uniform stress distribution through this staggered layout.

[0072] The wheel assembly provided in this embodiment includes a wheel hub 400 and a wheel hub decorative cover assembly, wherein the wheel hub 400 is provided with a plurality of spokes 410; as Figure 3 As shown, the inner side of the decorative cover 100 of the wheel hub decorative cover assembly is provided with a plurality of locking feet 300, which engage with the spokes 410.

[0073] The locking feet 300 can be evenly arranged around the perimeter of the decorative cover 100. The shape and size of the locking feet 300 match the shape of the spokes 410 of the wheel hub 400, forming a locking engagement structure. When the wheel hub decorative cover assembly is installed on the wheel hub 400, the locking feet 300 engage with the spokes 410 of the wheel hub 400, achieving reliable positioning and stable fixation of the decorative cover 100 relative to the wheel hub 400. By setting multiple locking feet 300 and corresponding spokes 410 for engagement, multi-point positioning and fixation between the decorative cover 100 and the wheel hub 400 are achieved, making the installation of the wheel hub decorative cover assembly more convenient and secure, and preventing the decorative cover 100 from loosening or falling off during driving.

[0074] In some implementations, such as Figure 8-9 As shown, the latch 300 includes a fixing block 310, a neck 320 and a latching part 330 connected in sequence. The fixing block 310 has a hollow structure. The neck 320 is connected to one side of the fixing block 310. A plurality of support ribs 340 are formed on the opposite side of the fixing block 310. The support ribs 340 are connected to both the fixing block 310 and the decorative cover 100.

[0075] The fixing block 310 adopts a hollow structure design to achieve lightweight while ensuring sufficient strength and rigidity. One end of the neck 320 is connected to the fixing block 310, and the other end extends to the snap-fit ​​portion 330, forming an elastic connection structure. This allows the snap-fit ​​foot 300 to deform appropriately during assembly, facilitating snap-fit ​​positioning. To enhance structural stability, the fixing block 310 has multiple support ribs 340 on the opposite side. These support ribs 340 are connected to both the fixing block 310 and the decorative cover 100, improving the overall bending and torsional resistance of the snap-fit ​​foot 300. This ensures that the snap-fit ​​foot 300 can withstand external loads during use, preventing loosening or breakage due to vibration or impact. This design, while prioritizing lightweight, improves the reliability of the secure connection between the decorative cover 100 and the wheel hub 400.

[0076] In some implementations, such as Figure 8-9 As shown, a U-shaped groove 350 is formed between the fixing block 310 and the neck 320. The locking foot 300 also includes an elastic member 360 disposed in the U-shaped groove 350. The elastic restoring force of the elastic member 360 causes the locking portion 330 to tend to move away from the fixing block 310.

[0077] The U-shaped groove 350 serves as an elastic deformation area, giving the retaining foot 300 a certain degree of flexibility and flexibility. The elastic element 360 can be a retaining spring that conforms to the shape of the U-shaped groove 350. Its function is to generate an elastic restoring force after the retaining foot 300 is compressed by external force, causing the U-shaped groove 350 to deform. This elastic restoring force drives the retaining part 330 to return to its initial position in a direction away from the fixing block 310, thereby ensuring that the retaining part 330 maintains good retaining force and stability during the engagement of the decorative cover 100 and the spokes 410 of the wheel hub 400, preventing loosening problems caused by vibration or impact, and improving the connection reliability between the wheel hub decorative cover assembly and the wheel hub 400.

[0078] This application also provides a vehicle that includes a wheel assembly as described in any of the above embodiments. The wheel assembly achieves a good decorative effect and robust fit through a reliable snap-fit ​​structure between the decorative cover 100 and the wheel hub 400. The multi-dimensional limiting design between the emblem cover 200 and the decorative cover 100 enhances the stability of the emblem cover 200 during use, effectively preventing loosening or detachment due to vibration, impact, or long-term use, thereby improving the overall appearance integrity and brand recognition of the vehicle. Furthermore, the decorative cover 100 is preferably made of aluminum alloy, achieving a lightweight design that helps optimize the overall vehicle weight, conforming to the modern automotive design trend of lightweighting and low wind resistance, and effectively improving the vehicle's energy efficiency and driving stability.

[0079] The above embodiments are merely preferred embodiments provided to fully illustrate this application, and the scope of protection of this application is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on this application are all within the scope of protection of this application.
