Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a decorative cover for automotive wheel hubs, and in particular a wheel hub floating cover that can keep the central pattern stable while the vehicle is in motion. Background Technology

[0002] Car wheel covers are used to cover the center of the wheel rim, serving not only to prevent dust and protect the bearings, but also as an important decorative element. To enhance the visual appeal, a "floating wheel cover" has emerged in the current technology. The principle behind this is that the center cover, which features a brand logo or pattern, remains stationary relative to the ground as the wheel rim rotates, thus ensuring that the logo is always in a positive position.

[0003] However, existing floating hubcap structures typically have the following problems: the working environment inside the hub is harsh, containing mud, water, and brake dust, which can easily penetrate the rotating mechanism, causing bearing jamming, sluggish rotation, and loss of the levitation effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hub suspension cover that reduces the influence of external factors on the bearing and improves the bearing service life.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wheel hub floating cover, including a base, a mounting seat fixed on the base, a rotating cover cooperating with the mounting seat, and a decorative component disposed on the rotating cover; the rotating cover is provided with a rotating shaft, the mounting seat is provided with a bearing, the rotating shaft cooperates with the bearing, and a receiving cavity is formed between the rotating cover and the mounting seat; an arc-shaped counterweight is provided on one side of the back of the rotating cover, and an arc-shaped protective plate is provided on the other side, the two ends of the arc-shaped protective plate extending to the two ends of the arc-shaped counterweight respectively, and an outer protective plate is provided on the edge of the rotating cover outside the arc-shaped protective plate, the outer protective plate being disposed on the outer wall of the mounting seat. The principle of this utility model: through the gravity of the arc-shaped counterweight, regardless of how the wheel hub rotates, the rotating cover can always automatically adjust under the action of gravity, ensuring that the counterweight side always faces downwards, thereby guaranteeing that the logo on the decorative component is displayed facing forward. The arc-shaped guard plate and the outer guard plate together form a labyrinthine sealing structure, which effectively blocks mud and water from entering from the side of the wheel hub, protects the bearings and shafts in the housing from contamination, and ensures smooth rotation over a long period of time.

[0006] As an improvement, the mounting base includes a mounting plate and a side plate disposed outside the mounting plate, the mounting plate, the side plate and the rotating cover forming the receiving cavity.

[0007] As an improvement, the upper end of the side plate is provided with a first flange extending outward.

[0008] As an improvement, the arc-shaped guard plate has a second flange extending outward at one end facing the mounting plate.

[0009] As an improvement, the accommodating cavity has a convex ring located in the middle of the mounting plate, the bottom of the convex ring has a through hole, the bearing is located inside the convex ring, one end of the rotating shaft is connected to the rotating cover, and the other end passes through the bearing and engages with the retaining spring.

[0010] As an improvement, the back of the rotating cover is provided with a raised annular groove in the middle, and the upper end of the raised ring extends into the annular groove.

The decorative plate is provided with connecting ears, and the edge of the through hole at the bottom of the groove is provided with a connecting seat. The connecting ears and the connecting seat are connected by screws.

[0014] The beneficial effects of this utility model compared with the prior art are: Through multiple labyrinthine sealing structures such as "arc-shaped protective plate + second flange", "outer protective plate + first flange" and "annular groove + convex ring", the product is protected layer by layer, effectively isolating external mud, sand, water and dust, and greatly improving its durability and reliability. Attached Figure Description

[0015] Figure 1 This is an exploded view of the present invention.

[0016] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] A wheel hub floating cover mainly consists of a base 1, a mounting base 2, a rotating cover 3, and a decorative component 4.

[0019] The base 1 is a disc-shaped structure with a central groove 11. A through hole, smaller in diameter than the groove 11, is formed at the bottom of the groove 11, creating an annular support plate. Multiple connecting seats 12 are located on the edge of the through hole, i.e., on the annular support plate. The mounting seat 2 is secured within the groove 11 by multiple first locking feet 25 at its bottom, engaging with the edge of the through hole. The front of the base 1 also features a decorative plate 8, its shape mirroring that of the base. The decorative plate 8 has connecting ears 81 that extend into the groove 11. Screws pass through the connecting ears 81 and are screwed into the connecting seats 12, fixing the decorative plate 8 to the base 1 and enhancing its appearance. The back of the base 1 has several second locking feet 9 and spring rings supporting the second locking feet 9. The second locking feet 9 engage with the central hole of the wheel hub, fixing the base 1 to the wheel hub.

[0020] Mounting base 2 includes a circular mounting plate 21 and a cylindrical side plate 22 extending vertically from the edge of the mounting plate 21. The upper end of the side plate 22 is provided with a first flange 23 extending horizontally outward. The center of the mounting plate 21 protrudes upward to form a convex ring 24, and the bottom of the convex ring 24 has a second through hole. The bearing 5 is pressed into the convex ring 24 or installed by in-mold injection molding.

[0021] The rotating cover 3 has a disc-shaped structure, with decorative components 4 (such as a brand logo) on its front. A downward-extending pivot 31 is located at the center of the back of the rotating cover 3. The upper end of the pivot is connected to the rotating cover 3, and the lower end of the pivot 31 passes through a bearing 5 on the mounting base 2 and is axially fixed by a retaining spring 6 to prevent the pivot 31 from dislodging from the bearing. After the rotating cover 3 is fastened onto the mounting base 2, it, together with the mounting plate 21 and the side plate 22, forms a sealed accommodating cavity.

[0022] To achieve the levitation function, an arc-shaped counterweight 32 is fixedly installed on one side of the back of the rotating cover 3. On the opposite side of the counterweight 32, an arc-shaped guard plate 33 is provided. The two ends of the arc-shaped guard plate 33 are bent forward and extend to the two ends of the counterweight 32. The arc-shaped counterweight 32 and the arc-shaped guard plate surround the central pivot 31 and bearing 5. On the edge of the arc-shaped guard plate 33 facing the mounting plate 21, a second flange 35 is provided that extends horizontally outward. In addition, on the edge of the rotating cover 3, outside the arc-shaped guard plate 33, a ring of downward-extending outer guard plate 34 is provided. After assembly, the outer guard plate 34 is located outside the side plate 22 of the mounting base 2 and forms a sealing gap with the first flange 23.

[0023] To enhance the sealing of the central rotating part, a raised annular groove 36 is provided around the center of the rotating cover 3 on the back side, forming a ring groove 36. The upper end of the raised ring 24 on the mounting base 2 extends into this annular groove 36, leaving a small gap between them to form a labyrinth seal. Finally, a cap 7 is used to seal the through hole at the bottom of the raised ring 24 on the back side of the mounting plate 21, thereby sealing from the bottom of the accommodating cavity.

[0024] The working process of this utility model is as follows: When the vehicle is in motion, the wheel hub drives the base 1 and mounting base 2 to rotate together. Since the rotating cover 3 is rotatably connected to the mounting base 2 via the shaft 31 and bearing 5, and has a heavy arc-shaped counterweight 32 on its back, the rotating cover 3 remains stationary relative to the ground under the influence of gravity. That is, the counterweight 32 always points towards the center of the earth, and the logo on the decorative component 4 always faces forward, creating a "floating" visual effect. Throughout the process, the composite sealing system consisting of the outer protective plate 34, the first flange 23, the arc-shaped protective plate 33, the second flange 35, and the annular groove 36 and the convex ring 24 effectively prevents external contaminants from entering the accommodating cavity, protecting the bearing 5 and the shaft 31, and ensuring the long-term smooth operation of the rotating cover 3.
