Description

Technical Field

[0001] This utility model relates to the technical field of automotive wheel hub decorative parts, and in particular to a floating wheel hub cover. Background Technology

[0002] With the increasing demand for car personalization and brand recognition, floating wheel covers have become widely used. They utilize a bearing structure to keep the central logo relatively stationary as the wheel rotates, thus creating the visual effect of a "car logo always standing upright." Existing floating wheel covers typically include a base, cover body, bearings, counterweights, and a logo plate. The bearings decouple the base from the cover body during rotation, achieving stability for the logo plate.

[0003] However, existing technical solutions still have the following shortcomings in practical use: Poor waterproof and dustproof performance: Water and dust can easily enter the bearing and its internal cavity, leading to bearing corrosion, accelerated wear, and reduced service life. Vibration and abnormal noise issues: The internal components of the hubcap are mostly in hard contact, which can easily cause vibration and resonance noise when the vehicle is running; Poor assembly structure stability: Traditional solutions use the clamps on the cover that assemble with the wheel hub directly as limiters. The clamps must both hook onto the wheel hub and withstand the pressing force during cover assembly. Under this dual force, the clamps are prone to outward deformation, resulting in a decrease in clamping force on the wheel hub side. Ultimately, this manifests as a decrease in push-pull force and an increased risk of loosening. Low modularity: The assembly of each component is complex, which is not conducive to rapid installation and subsequent maintenance. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems of waterproofing, dustproofing, and loosening in the prior art, and to provide a floating hub cover that has a double seal. The snap ring is axially locked by an independent support buckle to ensure that the car logo is stable and suspended for a long time without loosening or leaking water.

[0005] To solve the above-mentioned technical problems, this utility model provides a floating hub cover, comprising: A cover is used to be fixedly connected to the wheel hub and rotate with the wheel hub; several first snap-fit ​​blocks are arranged circumferentially on the inner side of the edge of the cover for connecting with the wheel hub shown. A base is coaxially arranged with the cover and rotates with the cover; the base is provided with a plurality of second snap-fit ​​blocks for connecting with the cover. A transparent cover is embedded in the cover body, and a first sealing ring is provided between the transparent cover and the cover body; A suspension assembly is disposed within the cavity formed by the base and the transparent cover; the suspension assembly includes an inertial suspension seat, a bearing, and a counterweight. The inertial suspension seat is rotatably connected to the base via the bearing, allowing the inertial suspension seat to rotate freely relative to the hub, and a second sealing ring is provided between the inertial suspension seat and the base; the counterweight is eccentrically mounted on the inertial suspension seat, so that the inertial suspension seat maintains a stable posture when the hub rotates; The signboard is fixed to the outside of the inertial suspension seat and remains stationary relative to the ground to achieve a floating visual effect; A retaining ring, fixedly mounted on the inner side of the cover by a support buckle, is used to axially lock the base to the hub; In one embodiment of this utility model, a silicone pad is provided circumferentially at the outer edge of the base.

[0006] In one embodiment of this utility model, the inertial suspension seat is press-fitted into the inner ring of the bearing, thereby decoupling the rotation from the base.

[0007] In one embodiment of this utility model, a decorative ring is further provided between the transparent cover and the cover body.

[0008] In one embodiment of this utility model, the outer surface of the decorative ring is provided with an electroplated layer, and is interference-fitted to the cover body by circumferentially distributed barbed feet.

[0009] In one embodiment of this utility model, the label plate is fixed to the outside of the inertial suspension seat by adhesive backing.

[0010] In one embodiment of this utility model, the bearing is a ball bearing, the outer ring of which is abutted against the base by a retaining ring with a hole, and the inner ring of which is abutted against the inertial suspension seat by a retaining ring with a shaft, thereby achieving axial bidirectional limiting.

[0011] In one embodiment of the present invention, the support buckle includes a support portion and a buckle portion, and the support portion and the buckle portion are integrally formed, and the support portion is provided with a groove that matches the outer diameter of the snap ring.

[0012] In one embodiment of this utility model, the cover and the transparent cover are fixed by welding to form a closed protective cavity for the signboard.

[0013] In one embodiment of this utility model, the inertial suspension seat and the counterweight are integrally injection molded PA+PPE composite structures.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: The floating hub cover of this utility model features a dual waterproof and dustproof design with a first sealing ring and a second sealing ring, which more effectively protects the floating cover from water and dust. The retaining spring is fixed to the inside of the cover body by an independent support buckle. When the cover body and the hub are connected by the first snap-fit ​​block, the risk of deformation of the support buckle is reduced, which can keep the clamping force on the hub side stable and the push and pull force will not decrease, thus improving driving safety.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0017] Reference Figure 1-5As shown, this utility model provides a floating hub cover, including: a cover body 1, for fixed connection with the hub and rotating with the hub; a plurality of first snap-fit ​​blocks 4 are arranged circumferentially on the inner side of the edge of the cover body 1 for connection with the hub shown; The base 2 is coaxially arranged with the cover 1 and rotates with the cover 1; the base 2 is provided with a plurality of second snap-fit ​​blocks 5 for connecting with the cover 1; the cover 1 is provided with a plurality of slots that are adapted to the second snap-fit ​​blocks 5. A suspension assembly is disposed within the cover 1; the suspension assembly includes an inertial suspension seat 6, a bearing 7, and a counterweight 9. The inertial suspension seat 6 is rotatably connected to the base 2 via the bearing 7, allowing the inertial suspension seat 6 to rotate freely relative to the hub, and a first sealing ring 8 is provided between the inertial suspension seat 6 and the base 2; the counterweight 9 is eccentrically mounted on the inertial suspension seat 6, so that the inertial suspension seat 6 maintains a stable posture when the hub rotates; The signboard 10 is fixed to the outside of the inertial suspension seat 6 and remains stationary relative to the ground to achieve a floating visual effect; A transparent cover 11 is embedded inside the cover 1 and covers the label plate 10; and a second sealing ring 12 is provided between the transparent cover 11 and the cover 1. The retaining ring 13, fixedly mounted on the inner side of the cover 1 by the support buckle 14, is used to axially lock the base 2 to the wheel hub. The retaining ring 13 is a stainless steel C-shaped ring, the outer diameter of which is larger than the inner diameter of the center hole of the wheel hub in the free state. After assembly, it generates an elastic expansion force, which can prevent the wheel hub cover from axially loosening. During assembly, the retaining ring 13 is pressed into the center hole of the wheel hub, the outer diameter expands elastically, and instantly locks into the groove in the hole, forming an irreversible axial stop. Vibrations, impacts, and thermal expansion and contraction generated during vehicle operation are all absorbed by the retaining ring 13, maintaining zero axial clearance between the base 2 and the wheel hub. Disassembly only requires special pliers to retract the retaining ring 13, without damaging any parts, achieving quick installation and disassembly.

[0018] Furthermore, a silicone pad 3 is provided on the cover 1 at the position where it abuts the wheel hub. The silicone pad 3 can prevent the cover 1 from colliding hard with the wheel hub, reduce vibration, increase cushioning, and solve the problem of vibration and abnormal noise.

[0019] In this embodiment, the base 2 is rigidly interlocked with the cover 1 by the second snap-fit ​​block 5, and the two are coaxially connected as one, rotating synchronously with the hub. When the cover 1 and the base 2 are axially engaged, after the circumferential snap-fit ​​block is locked, the base 2 and the cover 1 together form a cavity. This cavity is radially defined by the central boss of the base 2 and the annular wall of the cover 1, and axially held by the bottom wall of the base 2 and the top wall of the cover 1, thereby enclosing the bearing 7, the inertial suspension seat 6, and the counterweight 9, achieving integrated housing and rotational space isolation of the suspension components. At the same time, the inner side of the base 2 provides a rotational reference for the inertial suspension seat 6 through the bearing 7. The cover 1 undertakes the functions of appearance, sealing, and support for the transparent cover 11, forming... The suspension structure is based on the principle of "outer rotation, inner non-rotation"; the sign plate 10 and the inertial suspension seat 6 form the suspension core, and the transparent cover 11 is fixed to the cover 1 as a protective window, so that the sign plate 10 is always upright and presents a suspension visual effect; the first sealing ring 8 and the second sealing ring 12 form an L-shaped seal, which more effectively protects the suspension cover from water and dust; the retaining spring 13 is pre-installed on the inner side of the cover 1 by the support buckle 14, and automatically snaps into the wheel hub groove during assembly, providing axial locking force. Since the retaining spring 13 is fixed to the inner side of the cover 1 by the independent support buckle 14, the risk of deformation of the support buckle 14 is reduced, so that the clamping force on the wheel hub side remains stable and the push and pull force does not decrease, thus improving driving safety.

[0020] In this embodiment, the first sealing ring 8 is a circular sealing ring; the second sealing ring 12 is a strip-shaped sealing ring. The circular sealing ring is radially fitted between the transparent cover 11 and the cover body 1 to form a continuous circumferential seal; the end face of the strip-shaped sealing ring is laid between the base 2 and the inertial suspension seat 6 to provide axial compression seal; the two sealing forms complement each other to achieve a "radial + end face" L-shaped double seal, improving the overall sealing reliability and service life.

[0021] In this embodiment, the inertial suspension seat 6 is press-fitted into the inner ring of the bearing 7, thus decoupling it from the rotation of the base 2. The press-fitting of the inertial suspension seat 6 with the inner ring of the bearing 7 achieves zero-clearance transmission, eliminates wobbling, and ensures a stable visual effect of the car logo on the signboard 10 remaining upright and suspended.

[0022] Preferably, the signboard 10 is fixed to the outside of the inertial suspension seat 6 by adhesive 16. Adhesive 16 bonding replaces mechanical buckles, avoids drilling holes in the thin-walled signboard 10, reduces the risk of cracking, and at the same time reduces the thickness of the signboard 10, making the entire cover lighter and thinner.

[0023] like Figure 6As shown, the bearing 7 is a ball bearing. Its outer ring abuts against the base 2 by a retaining ring 17, and its inner ring abuts against the inertial suspension seat 6 by a retaining ring 18, achieving bidirectional axial limiting. The double retaining rings formed by the retaining ring 17 and the retaining ring 18 provide bidirectional axial limiting, which can withstand large impact loads and prevent the bearing 7 from shifting when the vehicle goes over potholes or changes lanes at high speed, ensuring the continuous effectiveness of the suspension function.

[0024] In this embodiment, a decorative ring 15 is also provided between the transparent cover 11 and the cover 1, and the decorative ring 15 is disposed on the inner circumference of the cover 1. The decorative ring 15 is embedded between the transparent cover 11 and the cover 1, which not only covers the welding / clamping scars, but also forms a third water barrier, improving the appearance quality and protection level.

[0025] like Figure 7 As shown, the outer surface of the decorative ring 15 is electroplated and is press-fitted to the outer edge of the cover 1 by circumferentially distributed barbed clips 19. The cover 1 is provided with several hook grooves that fit the barbed clips 19. The electroplating design of the decorative ring 15 allows it to be used for a long time without fading. Maintenance only requires replacing the decorative ring 15 for refurbishment. The design of the barbed clips 19 enables screwless quick disassembly, resulting in short assembly time.

[0026] like Figure 8 As shown, the support buckle 14 includes a support portion 141 and a buckle portion 142, with the support portion 141 and the buckle portion 142 integrally formed. The support portion 141 is provided with a groove 143 that matches the outer diameter of the retaining spring 13. The retaining spring 13 is inserted as a whole after pre-installation, and can be pushed in one piece during assembly, shortening the assembly time for a single piece. Furthermore, the groove 143 limits the opening of the retaining spring 13, preventing excessive expansion that could lead to permanent deformation.

[0027] Preferably, the cover 1 and the transparent cover 11 are fixed by welding to form a closed protective cavity for the marking plate 10.

[0028] In this embodiment, the inertial suspension seat 6 and the counterweight block 9 are integrally injection-molded PA+PPE composite structures. Most vehicles nowadays are new energy vehicles, with high wheel rim temperatures exceeding the temperature resistance limits of ABS+PC, which can easily cause product deformation. PA+PPE material has high temperature resistance, reaching temperatures that ABS+PC cannot, thus preventing product deformation. This ensures that even after a long downhill braking process in new energy vehicles, with a wheel hub temperature rise of 120°C, the dimensions remain stable, eliminating the risk of deflection of the marking plate 10 due to high-temperature eccentricity drift.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
