Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a fastener, wheel cover decorative insert, and wheel hub assembly. Background Technology

[0002] Wheel hubs play a crucial role in automobiles, supporting and bearing the vehicle's weight, maintaining balance and stability, and transmitting driving force and torque. Furthermore, the market offers wheel hub decorations to enhance the vehicle's appearance. This has led to the development of wheel hub covers, which are installed by connecting to the wheel hub. However, current methods using plastic clips offer relatively low connection strength, and the installation process is cumbersome due to the need for precise alignment of the clips. To address at least one of these technical issues, it is necessary to develop a fastener, a wheel hub cover insert, and a complete wheel hub assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a fastener, wheel cover decorative insert, and wheel hub assembly to solve the above-mentioned technical problems. The fastener body is provided with a first cavity for accommodating the elastic part, and the snap-fit ​​part penetrates through the fastener body. In use, the snap-fit ​​part can be retracted relative to the surface of the fastener body by pressing the end of the snap-fit ​​part to overcome the elastic action of the elastic part. When the snap-fit ​​part is in the unfolded state, it extends relative to the fastener body under the elastic action of the elastic part. When it is installed with the contact surface of the wheel hub, since the snap-fit ​​part penetrates through the fastener body, the radial plane of the snap-fit ​​part abuts against the part through which the fastener body is penetrated, thus bearing the load of the snap-fit ​​part. The snap-fit ​​part is kept in the extended state under the action of the elastic part, which enhances the installation strength of the fastener and avoids the problem of insecure installation and shaking.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A fastener includes a fastener body, wherein a fastener element is disposed inside the fastener body and is retractable relative to the surface of the fastener body;

[0006] The fastener body is provided with a first cavity;

Specifically, the fastener body has a fastener that can extend and retract relative to the radial surface of the fastener body; the latching portion extends and retracts relative to the fastener body; the fastener body has a first cavity for accommodating the elastic portion, and the latching portion penetrates the fastener body. In use, pressing the end of the latching portion causes it to retract relative to the surface of the fastener body, overcoming the elasticity of the elastic portion; the latching portion extends relative to the fastener body under the elasticity of the elastic portion. When installed to engage with the contact surface of the wheel hub, the radial plane of the latching portion abuts against the point through which the fastener body is penetrated, thus bearing the load. The latching portion remains extended under the action of the elastic portion, enhancing the installation strength of the fastener and preventing insecure installation and wobbling.

[0008] Preferably, the elastic part includes a first sheet and a second sheet that are connected to each other;

[0009] The first piece abuts against the inner wall of the first cavity;

[0010] The second piece is connected to the latching part.

The first through hole is disposed on the radial sidewall of the fastener body; the first through hole is disposed near the end of the fastener body, specifically at the end of the fastener body away from the connection between the first piece and the second piece; the first through hole provides a through space for the snap-fit ​​part, and when the snap-fit ​​part is connected to the contact surface, the plane where the first through hole is located continuously abuts against the radial surface of the snap-fit ​​part, thereby providing a bearing surface for the snap-fit ​​part and improving the installation strength and connection stability.

[0014] Preferably, the latching part is one of cylindrical, rhomboid, or square. The shape of the first through hole is adapted to the shape of the latching part.

[0015] Preferably, the cross-section of the fastener body perpendicular to the axial direction is polygonal or circular.

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0033] The technical solution of this utility model will be described in detail below with specific embodiments.

[0034] Reference Figures 1 to 9 A fastener includes a fastener body 1, wherein a fastener body 2 is provided inside the fastener body 1 and is retractable relative to the surface of the fastener body 1.

[0035] The fastener body 1 is provided with a first cavity 11;

[0036] The fastener 2 includes an elastic part 21 disposed in the first cavity 11 and a snap-fit ​​part 22 connected to the elastic part 21 and penetrating the fastener body 1. Specifically, the fastener body 1 has a fastener body 2 that can extend and retract relative to the radial surface of the fastener body 1; the latching part 22 extends and retracts relative to the fastener body 1; the fastener body 1 has a first cavity 11 for accommodating the elastic part 21, and the latching part 22 penetrates the fastener body 1. In use, the latching part 22 can be retracted relative to the surface of the fastener body 1 by pressing the end of the latching part 22 to overcome the elastic action of the elastic part 21; when the latching part 22 is in the unfolded state, it extends relative to the fastener body 1 under the elastic action of the elastic part 21. When it is installed with the contact surface of the wheel hub, since the latching part 22 penetrates the fastener body 1, the radial plane of the latching part 22 abuts against the part of the fastener body 1 through which it is penetrated, thus bearing the load of the latching part 22. The latching part remains in the extended state under the action of the elastic part, which enhances the installation strength of the fastener and avoids the problem of insecure installation and shaking.

[0037] The elastic part 21 includes a first sheet 211 and a second sheet 212 that are connected to each other;

[0038] The first piece 211 abuts against the inner wall of the first cavity 11;

[0039] The second piece 212 is connected to the latching part 22. The first piece 211, which abuts against the first cavity 11, works with the second piece 212 to apply a corresponding elastic force to the latching part 22, so that the latching part 22 remains extended relative to the surface of the fastener body 22, thereby connecting and installing with the contact surface; when the latching part 22 needs to be retracted, pressing the end of the latching part 22 causes the latching part 22 to overcome the elastic action of the first piece 211 and the second piece 212 and retract relative to the surface of the fastener body 1. The method of use is simple and easy to implement.

[0040] The latching part 22 is connected to the side of the second piece 212 away from the first piece 211.

[0041] The elastic part 21 is V-shaped. One end of the elastic part 21 can abut against the first cavity 11 to provide support, and the other end of the elastic part 21 is connected to the buckle part 22, so that the buckle part 22 can extend and retract relative to the fastener body 1.

[0042] The fastener body 1 has a first through hole 12 in the vertical direction along the axial direction, and the snap-fit ​​part 22 is disposed in the first through hole 12. The first through hole 12 is disposed on the side wall in the radial direction of the fastener body 1; the first through hole 12 is disposed near the end of the fastener body 1, specifically at the end of the fastener body 1 away from the connection between the first piece 211 and the second piece 212; the first through hole 12 provides a through space for the snap-fit ​​part 22, and when the snap-fit ​​part 22 is connected to the contact surface, the plane where the first through hole 12 is located continuously abuts against the radial surface of the snap-fit ​​part 22, thereby providing a bearing surface for the snap-fit ​​part 22 and improving the installation strength and connection stability.

[0043] The latching part 22 is one of cylindrical, rhomboid, or square. The shape of the first through hole 12 is adapted to the shape of the latching part 22.

[0044] The cross-section of the fastener body 1 in the vertical direction along the axial direction is polygonal or circular. In this technical solution, the cross-section of the fastener body 1 in the vertical direction along the axial direction is hexagonal, which improves the stability of the fastener body 1 during the connection process.

[0045] One or more reinforcing ribs 13 are provided on the surface of the fastener body 1. In this technical solution, two reinforcing ribs are provided to improve the rigidity of the fastener body.

[0046] A wheel cover decorative insert includes a decorative cover 3, which is connected to fasteners. In this technical solution, the decorative cover 3 is connected to four fasteners.

[0047] A wheel assembly, including a wheel hub 4 and a wheel cover decorative insert;

[0048] The hub 4 is provided with a mounting through hole 41, and the hub 4 is provided with a contact surface 42 at the mounting through hole 41, and the contact surface 42 is provided on the inner side of the hub 4.

[0049] The fastener passes through the mounting hole 41 and abuts against the contact surface 42. The decorative cover 3 is made of plastic; the fastener is made of metal.

[0050] Specifically, the fastener body 1 penetrates the mounting through hole, and the elastic part 21 causes the latching part 22 to extend out under the limited stroke of the first through hole 12. The radial surface of the latching part 22 abuts against the contact surface 42. This restricts the fastener from disengaging from the inside to the outside of the hub 4. Projecting along the axial direction of the hub 4, the projection surface of the decorative cover 3 is larger than the projection surface of the mounting through hole 41, preventing the decorative cover 3 from moving from the outside to the inside of the hub 4, thus completing the installation of the decorative cover 3. After the fastener body 1 penetrates the mounting through hole 41, the latching part 22 abuts against the contact surface 42 for connection, eliminating the need for alignment operations in the prior art, making the installation method convenient. Furthermore, the latching part 22 penetrates the fastener body 1, causing the radial plane of the latching part 22 to abut against the point where the fastener body 1 is penetrated, thus bearing the load of the latching part 22. The latching part 22 remains extended under the action of the elastic part 21, enhancing the installation strength of the fastener and preventing the problem of insecure installation and shaking.

[0051] The decorative cover 3 is provided with four fasteners, all of which abut against the contact surface 42. The mounting through hole 41 is fan-shaped, and the fasteners are installed symmetrically with the line connecting the mounting through hole 41 and the center of the wheel hub 4 as the axis of symmetry.

[0052] Define the inner side of the wheel hub as A; and the outer side of the wheel hub as B.
