Description

Technical Field

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

[0002] Because car wheel hubs have a center hole in the rim due to manufacturing reasons, the floating wheel hub cover is a device specifically designed to cover this center hole. Since the floating wheel hub cover has a floating logo decorative cover on its surface, it can maintain a stable posture while the car is in motion and can clearly display the car's brand. Therefore, it is widely used in the industry. Existing floating wheel hub covers are usually assembled by using clips on the inner cover to engage with the outer edge of the rim center hole. However, due to cost considerations, the inner cover is mostly made of plastic. Plastic materials are prone to aging and loss of elasticity over long-term use. Furthermore, the tires rotate at high speeds while the car is in motion. Therefore, under certain circumstances, the floating wheel hub cover may detach from the wheel hub due to insufficient engagement force. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a suspended wheel core cover assembly structure that can improve the stability after assembly and reduce the risk of falling off.

[0004] To solve the above-mentioned technical problems, the present invention provides a floating wheel hub cover assembly structure, which is mounted on an automobile wheel hub and includes: an inner cover, an outer cover, a logo decorative cover, a bearing seat, and a floating bearing. The inner cover has an inwardly protruding assembly groove, and the bearing seat is fixed in the assembly groove. The logo decorative cover is connected to the bearing seat through the floating bearing. The outer cover is arranged around the logo decorative cover and is tightly fixed to the inner cover. The inner side of the inner cover is provided with multiple sets of locking structures and multiple positioning protrusions provided at the top of the center hole of the wheel rim. Each set of locking structures includes an elastic locking foot and at least one lower support post. The lower support post is located outside the elastic locking foot and its top matches the shape of the lower surface of the positioning protrusion. The outer side of the top of the elastic locking foot is provided with a hub locking block that matches the shape of the upper surface of the positioning protrusion. A retaining spring groove is provided behind the elastic locking foot. Multiple elastic locking feet are supported by a multi-leg retaining spring with a zigzag pattern. The multi-leg retaining spring has multiple zigzag support feet, and one zigzag support foot is inserted into each retaining spring groove. The inner side of the inner cover is also provided with a positioning post, and the corresponding position on the hub is provided with a positioning hole that matches the positioning post.

[0005] In a preferred embodiment of this utility model, at least one set of locking structures has a retaining spring positioning post on its inner side, and there are two retaining spring positioning posts that can just lock the inner side of a zig-shaped support foot.

[0006] In a preferred embodiment of this utility model, each set of locking structures includes two support columns, which are symmetrically arranged about the elastic locking foot.

[0007] In a preferred embodiment of this invention, an anti-rotation post is further provided on the inner side of the inner cover, and the anti-rotation post and the positioning post are respectively located on both sides of the assembly groove. There are at least two anti-rotation posts, which are respectively engaged with the edges of two adjacent positioning protrusions on the corresponding sides.

[0008] In a preferred embodiment of this utility model, the plane formed by the line connecting the snap ring slots on all the elastic snap ring feet does not exceed the bottom surface of the assembly groove.

[0009] In a preferred embodiment of the present invention, the suspended wheel core cover is further provided with a disassembly hole that penetrates the inner cover and the outer cover.

[0010] The beneficial effects of this utility model are as follows: By optimizing the existing locking and engaging structure between the floating wheel hub cover and the wheel hub, this utility model provides continuous support to the locking foot by installing a retaining spring behind the locking foot without changing the material. This ensures that the locking to the wheel hub can be maintained even if the elasticity of the locking foot itself decreases. This effectively improves the durability of the connection between the floating wheel hub cover and the wheel hub, enhances the service life of the floating wheel hub cover, and reduces the probability of accidental detachment during driving.

[0012] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0013] Please see Figure 1 and Figure 2 The embodiments of this utility model include: A floating wheel hub cover assembly structure is provided, which is assembled on a car wheel hub. The structure includes: an inner cover 1, an outer cover 2, a logo decorative cover 3, a bearing seat 5, and a floating bearing 4. The inner cover 1 has an inwardly protruding assembly groove 102. The bearing seat 5 is fixed within the assembly groove 102. The logo decorative cover 3 is connected to the bearing seat 5 via the floating bearing 4. The outer cover 2 is arranged around the logo decorative cover 3 and is tightly fixed to the inner cover 1. The inner side of the inner cover 1 has six sets of locking structures that match six positioning protrusions at the top of the rim center hole of the wheel hub 6. Each set of locking structures includes an elastic locking foot 103 and two lower support columns 104. 04 is located outside the elastic foot 103 and is symmetrical about the elastic foot 103. The top of the lower support column 104 matches the shape of the lower surface of the positioning protrusion. The outer side of the top of the elastic foot 103 is provided with a hub block 1032 that matches the shape of the upper surface of the positioning protrusion. The elastic foot 103 is provided with a retaining spring groove 1031 behind it. The six elastic feet 103 are supported by a six-legged retaining spring 101. The six-legged retaining spring 101 is surrounded by six zig-shaped support feet. Each retaining spring groove 1031 is fitted with a zig-shaped support foot. The inner side of the inner cover 1 is also provided with a positioning post 106. The hub 6 is provided with a positioning hole that matches the positioning post 106 at the corresponding position.

[0014] One set of locking structures has two retaining spring positioning posts 108 on its inner side, which are just enough to lock the inner side of one of the Z-shaped support legs. This prevents the Z-shaped six-leg retaining spring 101 from rotating or even falling off during movement, thus affecting its service life.

[0015] The inner cover 1 is also provided with an anti-rotation post 105 on its inner side. The anti-rotation post 105 and the positioning post 106 are respectively located on both sides of the assembly groove 102. There are two anti-rotation posts 105. During assembly, they can be respectively locked onto the edges of two adjacent positioning protrusions, which can distribute the force on the positioning post 106 and improve the stability of the floating wheel core cover.

[0016] The plane formed by the line connecting all the retaining ring slots 1031 on the elastic retaining feet 103 does not exceed the bottom surface of the assembly slot 102. In this way, the six-pin retaining rings 101 will not touch other parts of the wheel hub 6 during the assembly process, which facilitates assembly by on-site personnel.

[0017] The suspension wheel cover is also provided with a disassembly hole 107 that passes through the inner cover 1 and the outer cover 2, so as to facilitate disassembly during subsequent maintenance after installation.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
