Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology, and in particular relates to a multi-point fixed wheel hub decorative cover. Background Technology

[0002] Wheel hub covers are components installed on the outside of car wheel hubs to beautify the appearance of the wheel hubs, prevent dust from entering, and protect the wheel hub bolts; most existing wheel hub covers are connected to the wheel hubs using a single method of clip-on or bolt fixing.

[0003] Clip-on connections are prone to loosening and loss due to vehicle vibrations, while bolt-on fastening is secure but cumbersome to install and remove, requiring specialized tools and making it inconvenient for users to quickly clean or replace wheel hub covers.

[0004] In addition, a single fixing point or fixing method can easily cause relative displacement or abnormal noise between the decorative cover and the wheel hub when subjected to lateral impact or long-term vibration, affecting the aesthetics and user experience. Utility Model Content

[0005] This utility model addresses the problems existing in the prior art by proposing the following technical solution: A multi-point fixed wheel hub decorative cover includes a decorative cover and a wheel hub. The decorative cover is detachably connected to the outer side of the wheel hub via a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a first insertion component disposed on the outer wall of the decorative cover, a second insertion component disposed on the side wall of the decorative cover, and an elastic locking component disposed within the second insertion component.

[0006] The first plug-in assembly includes at least two fixing blocks symmetrically fixed to the outer wall of the decorative cover and at least two lead plugs symmetrically fixed to the outer wall of the decorative cover and located outside the fixing blocks; the outer wall of the hub is provided with plug-in holes that are adapted to the position and shape of the fixing blocks, and the outer wall of the hub is also symmetrically provided with Y-shaped grooves that are adapted to the position and shape of the lead plugs.

[0007] The second insertion assembly includes an outer insertion block symmetrically fixed to the side wall of the decorative cover, which can be inserted into a corresponding slot in the side wall of the wheel hub. The elastic locking assembly is installed inside the outer insertion block and includes a movable cavity in the side wall of the outer insertion block, an insertion block slidably disposed in the movable cavity, and an elastic element disposed in the movable cavity for driving the insertion block to pop outward. The side wall of the wheel hub has a convex groove corresponding to the position of the insertion block. When the outer insertion block is inserted into the slot of the wheel hub, the insertion block pops out under the drive of the elastic element and inserts into the convex groove to achieve locking.

[0008] As a preferred embodiment of the above technical solution, the sidewall of the plug block is symmetrically fixed with sliders, and the inner wall of the movable cavity is symmetrically provided with slide rails that slide and cooperate with the sliders, so as to ensure that the plug block extends and retracts smoothly along a straight line.

[0009] As a preferred embodiment of the above technical solution, the elastic element is a compression spring.

[0010] As a preferred embodiment of the above technical solution, the cross-sectional shape of the guide plug is adapted to the cross-sectional shape of the Y-shaped groove, which is used to guide the decorative cover and the wheel hub to be precisely aligned during installation.

[0011] The beneficial effects of this utility model are as follows: In this application, a multi-point fixing method combining radial and axial fixing is used; the fixing block cooperates with the wheel hub insertion hole to provide radial support and limit, preventing the decorative cover from wobbling radially; the outer block cooperates with the insertion block and the convex groove to provide axial locking force, preventing the decorative cover from axially dislodging; the multiple fixing points work together to significantly improve the connection rigidity and integrity between the decorative cover and the wheel hub, effectively resisting vibration and lateral impact during driving, and avoiding abnormal noise or loosening; The design of the insertion block and the Y-shaped groove allows users to easily and quickly align all the mating points on the wheel hub when installing the decorative cover. The flared structure of the Y-shaped groove has error tolerance and guiding functions. Even if there is a slight deviation, it can automatically correct the alignment during the insertion process, guiding the insertion block and the fixing block to accurately enter their respective slots / holes. This greatly reduces the difficulty of installation, realizes "blind operation" or quick alignment, and improves the user experience. The elastic locking mechanism achieves a one-way self-locking function. During installation, simply align the decorative cover with the position and press it down. After the plug is compressed back, it automatically springs into the convex groove under the action of the elastic element to complete the locking, without any tools required. During disassembly, the user only needs to press the plug inward from the side of the wheel hub with their fingers or a simple tool to make it retract into the movable cavity and disengage from the convex groove, and the decorative cover can be easily removed as a whole. The entire disassembly and assembly process can be completed by hand, which is extremely convenient. It makes minimal changes to the original shape of the decorative cover and wheel hub, is easy to adapt to or modify existing wheel hub products, has controllable production costs, and has high market promotion value.

[0014] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments; like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the multi-point fixed wheel hub decorative cover is mainly composed of a decorative cover 1 and a wheel hub 5; the decorative cover 1 is installed on the outer surface of the wheel hub 5 through an integrated disassembly and assembly mechanism.

[0015] The disassembly and assembly mechanism mainly includes three parts: a first insertion component located on the outer wall of the decorative cover 1 (the surface facing the center of the wheel hub), a second insertion component located on the side wall (circumferential side) of the decorative cover 1, and an elastic locking component built into the second insertion component.

[0016] The first insertion assembly functions to achieve the initial radial positioning and fixation of the decorative cover 1 and the hub 5. Multiple fixing blocks 2 are integrally formed or fixed symmetrically on the inner wall (i.e., outer wall) of the decorative cover 1. In this embodiment, there are two fixing blocks 2, centrally symmetrically distributed. Two guide blocks 3 are also symmetrically arranged on the outer side of the fixing blocks 2 (closer to the edge of the decorative cover). The cross-section of the guide blocks 3 is preferably a shape that matches the Y-shaped groove 4 described later, for example, having a guide slope. On the outer surface of the hub 5 at the corresponding position, insertion holes (not shown separately in the figure) corresponding to the fixing blocks 2 are machined, as well as Y-shaped grooves 4 corresponding to the guide blocks 3. The entrance of the Y-shaped groove 4 is flared to facilitate the introduction of the guide blocks 3.

[0017] The second insertion assembly and elastic locking assembly: their function is to achieve the final locking and releasing of the decorative cover 1 and the wheel hub 5 in the axial direction; two outer insertion blocks 6 are symmetrically fixed on the circumferential sidewall of the decorative cover 1; each outer insertion block 6 is provided with an elastic locking assembly; the elastic locking assembly specifically includes: a movable cavity 7 opened in the sidewall of the outer insertion block 6 (pointing towards the center of the wheel hub 5), an insertion block 11 that can slide in the movable cavity 7, and a compression spring as an elastic element 8; the compression spring 8 is placed in the movable cavity 7, one end of which abuts against the bottom inner wall of the movable cavity 7, and the other end abuts against the inner end face of the insertion block 11, initially Finally, a thrust is applied to the plug-in block 11 outward from the movable cavity 7 (i.e. towards the hub 5). To ensure that the plug-in block 11 moves smoothly and without deflection, sliders 9 are symmetrically arranged on the two side walls of the plug-in block 11, and a slide rail 10 that precisely matches the sliders 9 is machined on the inner wall of the movable cavity 7. The sliding fit between the sliders 9 and the slide rail 10 strictly restricts the plug-in block 11 to move linearly along the axis of the movable cavity 7. A slot is provided on the side wall of the hub 5 (corresponding to the position where the outer plug-in block 6 is inserted) for the outer plug-in block 6 to be inserted. At the same time, a convex groove 12 that is directly opposite the position of the plug-in block 11 is provided on the inner side wall of the slot.

[0018] Working principle and process: During installation: First, the user aligns the decorative cover 1 with the wheel hub 5; guided by the flared end of the Y-shaped groove 4, the guide block 3 automatically corrects its position and slides into the narrow part of the Y-shaped groove 4; simultaneously, the fixing block 2 is also inserted into the corresponding insertion hole on the wheel hub 5, completing the initial radial positioning and fixing; then, continue pressing the decorative cover 1 towards the wheel hub 5, and the outer block 6 begins to insert into the hole groove on the side wall of the wheel hub 5; when the tip of the insertion block 11 contacts the side wall of the wheel hub 5 or the edge of the hole groove, it is subjected to inward pressure, pushing the insertion block 11 to overcome the pressure. The spring force of the compression spring 8 contracts into the movable cavity 7, and the slider 9 slides smoothly along the slide rail 10. When the decorative cover 1 is pressed into place, that is, when the outer insert 6 is fully inserted into the slot, the insert block 11 moves to the position aligned with the convex groove 12 on the side wall of the hub 5. At this time, the elastic potential energy stored in the compression spring 8 is released, and the insert block 11 is quickly pushed outward, so that its head is stuck in the convex groove 12. Due to the locking effect of the convex groove 12 on the insert block 11, the decorative cover 1 is firmly axially locked on the hub 5, completing the entire installation and locking process.

[0019] During disassembly: When the user needs to remove the decorative cover 1, simply locate the outer side of the opening of the convex groove 12 from the side of the hub 5, and press the exposed head of the plug block 11 inward with your finger or a small tool (such as a key); the plug block 11 will retract into the movable cavity 7 under pressure, and its head will completely disengage from the convex groove 12; at this time, the axial locking is released; the user can simply pull the decorative cover 1 outward to pull the outer plug 6 out of the hole groove of the hub 5, and at the same time the fixing plug 2 and the lead plug 3 will also disengage from the plug hole and Y-shaped groove 4 of the hub 5 respectively, thus easily removing the entire decorative cover 1.

[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
