Description

Technical Field

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

[0002] To enhance the overall look, existing high-end wheel hub covers generally employ a structure combining a metal decorative panel with a plastic base. The connection methods are mainly as follows: Adhesive bonding: A thin metal plate is glued to a plastic base using adhesive. This method has obvious disadvantages: the adhesive is prone to aging and failure under the long-term high temperature of the wheel hub (from brake heat), causing the metal plate to fall off; and it has poor impact and vibration resistance, posing a driving safety hazard.

[0003] Simple mechanical connections: such as designing claws on a plastic base to directly hold the edge of the metal plate. This method is not strong enough for heavy metal plates, and there is a risk that the metal plate will loosen and fly out under the huge centrifugal force generated by high-speed rotation.

[0004] Bolted connection attempts: There are existing ideas for using bolted connections, but their structural designs are often unreasonable. For example, the bolt may be directly screwed onto the plastic threads of the plastic base, which has low strength and is prone to stripping.

[0005] Therefore, existing technologies lack a connection solution that can provide high strength, high reliability, high temperature resistance, and easy installation for heavy metal decorative panels. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a wheel hub decorative cover with an optimized bolt connection structure to ensure a sturdy and durable connection between the thick aluminum decorative plate and the plastic base.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wheel hub decorative cover, including a plastic base and a thick aluminum decorative plate fixed on the plastic base. The front of the plastic base has a groove, and the bottom of the groove has a through hole. The back of the plastic base has a retaining foot. The back of the thick aluminum decorative plate is in contact with the front of the plastic base, and the back of the thick aluminum decorative plate has a protrusion corresponding to the groove position. The protrusion has a threaded hole, and a bolt passes through the through hole and is locked at the threaded hole. The principle of this utility model is as follows: the plastic base is fixed to the center hole of the wheel hub by the retaining foot on the back; the protrusion on the back of the thick aluminum decorative plate, with a threaded hole, strengthens the threaded connection, and the threaded hole is a blind hole, not affecting the appearance of the thick aluminum decorative plate; the protrusion on the thick aluminum decorative plate cooperates with the groove on the plastic base, serving to position the installation and prevent rotation.

[0008] As an improvement, the plastic base includes an annular support plate, the groove is provided on the front of the annular support plate, the locking feet are provided on the back of the annular support plate, the locking feet are evenly distributed around the circumference, and through holes are provided between adjacent locking feet.

[0009] As an improvement, the back of the annular support plate is provided with a first annular protrusion, the first annular protrusion is coaxial with the annular support plate, and the root of the clamping foot is connected to the first annular protrusion.

[0010] As an improvement, the front side of the annular support plate is provided with a second annular protrusion, which is coaxial with the annular support plate and abuts against the back side of the thick aluminum decorative plate.

[0011] As an improvement, the thick aluminum decorative panel is annular and coaxial with the annular support plate.

[0012] As an improvement, the thick aluminum decorative panel is formed by a forging process.

[0013] As an improvement, the thickness of the thick aluminum decorative panel is 2-5mm.

[0014] As an improvement, the front side of the thick aluminum decorative panel is provided with a decorative layer.

[0015] The beneficial effects of this utility model compared with the prior art are: Robust and reliable: The connection is made by mechanically locking bolts from the back, which is much stronger than adhesive bonding, avoiding the risk of falling off and can withstand centrifugal force and vibration during high-speed driving; Premium feel: The thick forged aluminum plate provides an excellent metallic texture and weight, significantly enhancing the product's grade and visual appeal; Reasonable structure: Positioning is achieved through the cooperation of grooves and protrusions, and support is provided by the second annular protrusion, which ensures assembly accuracy and overall structural stability.

[0019] Figure 4 This is a schematic diagram of the plastic base. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1As shown, a wheel hub decorative cover includes a plastic base 2 and a thick aluminum decorative plate 1 fixed on the plastic base 2.

[0022] like Figures 2 to 4 As shown, the plastic base 2 includes an annular support plate 21. The plastic base 2 is installed at the center hole of the wheel hub, and a center cover of the wheel hub can be installed inside the plastic base 2. The front side of the annular support plate 21 has several circumferentially evenly distributed grooves 22. The grooves 22 are integrally injection molded with the annular support plate 21, and a bulge is formed on the back side of the annular support plate 21 corresponding to the grooves 22. The bottom of the grooves 22 has a through hole 27 for passing through a bolt 3. The back side of the annular support plate 21 has several retaining feet 25 and spring rings 26 supporting the retaining feet 25. The retaining feet 25 are evenly distributed circumferentially, and a through hole 27 is provided between adjacent retaining feet 25. The retaining feet 25 mate with the center hole of the wheel hub. The back side of the annular support plate 21 has a first annular protrusion 23. The first annular protrusion 23 is coaxial with the annular support plate 21, and the root of the retaining foot 25 is connected to the first annular protrusion 23. The first annular protrusion 23 can strengthen the retaining foot 25. The front side of the annular support plate 21 is provided with a second annular protrusion 24, which is coaxial with the annular support plate 21. The second annular protrusion 24 abuts against the back side of the thick aluminum decorative plate 1, providing stable axial support.

[0023] like Figure 2 , 3 As shown, the thick aluminum decorative panel 1 is annular and coaxial with the annular support plate 21. After the back of the thick aluminum decorative panel is attached to the front of the plastic base 2, the thick aluminum decorative panel 1 can cover the annular support plate 21. The thickness of the thick aluminum decorative panel 1 is 2-5mm, formed by forging to ensure that it has extremely high density, strength and good metallic texture. The front of the thick aluminum decorative panel 1 can be provided with a decorative layer, such as a decorative layer formed by engraving, etching, spraying, electroplating and other processes. A decorative layer similar to the surface texture of the wheel hub can be designed to improve the overall integrity of the wheel hub surface. The back of the thick aluminum decorative panel 1 has a protrusion 11 corresponding to the groove 22. The protrusion 11 has a threaded hole 12. The threaded hole 12 is a blind hole. The bolt 3 passes through the through hole 27 from the back of the plastic base 2 and finally screws into the threaded hole 12 on the protrusion 11 of the thick aluminum decorative panel and locks it. After assembly, the head of the bolt 3 is hidden between the clips 25, which does not affect the installation and has a neat appearance.

[0024] The principle of this utility model is as follows: the plastic base 2 is fixed to the center hole of the wheel hub by the clips on the back; a protrusion 11 is added to the back of the thick aluminum decorative plate 1, and a threaded hole 12 is provided on the protrusion 11, which can strengthen the strength of the threaded connection. Moreover, the threaded hole 12 is a blind hole and does not affect the appearance of the thick aluminum decorative plate 1; the protrusion 11 on the thick aluminum decorative plate 1 cooperates with the groove 22 on the plastic base 2 to play the role of installation positioning and anti-rotation.
