Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a wheel hub cover for preventing loosening. Background Technology

[0002] Wheel hubcaps are decorative and protective components installed on the outside of car wheel hubs.

[0003] Most existing wheel hub covers are directly fixed to the wheel hub frame using simple clips or bolts. During long-term vehicle operation, due to bumps and vibrations, the clips may fail or the bolts may loosen, causing the wheel hub cover to fall off. This not only affects the appearance but may also pose a safety hazard. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by proposing the following technical solution: An anti-loosening hubcap includes a hubcap body and a hub frame. The hubcap body is detachably connected to the hub frame via a locking mechanism. The locking mechanism includes an insertion component disposed on the inner wall of the hubcap body and a limiting component disposed on the outer wall of the hubcap body. The insertion component is used to engage with a corresponding structure on the side wall of the hub frame to achieve initial positioning and fixation. The limiting component is used to engage with a corresponding structure on the outer wall of the hub frame to lock and provide auxiliary locking force.

[0005] As a preferred embodiment of the above technical solution, the plug-in assembly includes at least one plug-in block and at least one plug-in plate; the plug-in block is fixed to the inner wall of the hub cover body and can be inserted into the first mounting hole opened in the side wall of the hub frame; the plug-in plate is fixed to the inner wall of the hub cover body outside the plug-in block and can be inserted into the strip-shaped groove opened in the side wall of the hub frame.

[0006] As a preferred embodiment of the above technical solution, at least one bolt is further provided between the hub cover body and the hub frame. The bolt passes through the through holes on the hub cover body and the hub frame in sequence and is locked with a nut.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes two side plates symmetrically fixed to the upper and lower outer walls of the hubcap body; each side plate has a movable cavity inside; a limiting plate is movably disposed in the movable cavity; the inner end of the limiting plate can be inserted into the Y-shaped groove opened in the upper and lower outer walls of the hub frame; a pull rod is connected to the outer end of the limiting plate, and the outer end of the pull rod passes through the outer wall of the side plate and is fixedly connected to a pull plate.

[0008] As a preferred embodiment of the above technical solution, at least one elastic element is connected between the outer wall of the limiting plate and the inner wall of the movable cavity.

[0009] As a preferred embodiment of the above technical solution, the sidewall of the limiting plate is symmetrically fixed with sliders, and the inner wall of the movable cavity is correspondingly provided with a slide rail that slides and engages with the sliders.

[0010] The beneficial effects of this utility model are as follows: In this application, by setting up a plug-in assembly consisting of a plug-in block, a plug-in plate, and bolts, the initial positioning and main fixation of the hub cover body and the hub frame are achieved; at the same time, by adding a limiting assembly consisting of a limiting plate and a Y-shaped groove plug-in engagement, an independent auxiliary locking force is formed; the two mechanisms are independent of each other and work together, so even if one mechanism becomes slightly loose under long-term severe vibration, the other mechanism can still provide effective restraint, which greatly reduces the risk of overall loosening and the stability is significantly better than that of traditional hub covers with a single fixing method; In the limiting assembly, the elastic force of the elastic element drives the limiting plate to automatically insert into the Y-shaped groove, realizing a self-locking function. No additional tools are needed to lock this part during installation. During disassembly, simply pull the pull plate outward to overcome the elastic force and allow the limiting plate to exit the Y-shaped groove. The operation is simple and quick. The cooperation between the slide rail and the slider ensures the linearity and smoothness of the limiting plate's movement, prevents jamming, and improves the operating feel and the life of the mechanism. All locking mechanisms are integrated into the hubcap body and its attached side plates, resulting in a compact structure that does not occupy additional space and has minimal impact on the overall appearance of the hub. The design principle is clear and can be adapted to the size of different hub models, demonstrating good versatility and scalability. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0014] like Figure 1 and Figure 2As shown in the embodiment of this utility model, the anti-loosening hub cover mainly includes a hub cover body 1 and a hub frame 4 for mounting the hub cover body 1; the hub cover body 1 is detachably and securely connected to the hub frame 4 through a set of composite locking mechanisms.

[0015] Structure of the plug-in assembly: The plug-in assembly of the locking mechanism is mainly used to achieve the initial positioning and basic fixation of the hub cover body 1. Specifically, two plug-in blocks 2 are symmetrically fixedly installed on the inner wall of the hub cover body 1, i.e., the side facing the hub frame 4. During installation, these two plug-in blocks 2 are respectively aligned and inserted into two pre-drilled circular first mounting holes on the side wall of the hub frame 4, i.e., the axial end face of the hub. On the inner wall of the hub cover body 1 outside each plug-in block 2, a plug-in plate 3 is also fixedly installed. The end of the plug-in plate 3 can be inserted into the strip-shaped slot on the side wall of the hub frame 4. The cooperation between the plug-in block 2 and the first mounting hole mainly bears radial limit, while the cooperation between the plug-in plate 3 and the strip-shaped slot can better bear some circumferential and axial forces. In addition, through holes are also opened at the corresponding center positions of the hub cover body 1 and the hub frame 4. A bolt 5 is passed through in sequence and locked with a nut to form the core axial compression fixation. The plug-in block 2, the plug-in plate 3 and the bolt 5 together constitute the first anti-loosening barrier.

[0016] To further enhance the anti-loosening effect, this utility model adds an independent limiting component; on the upper and lower outer walls of the hub cover body 1, i.e., the outer edges of the decorative surface opposite to the hub frame 4, a vertical side plate 14 is fixed by welding or integral molding; a cylindrical movable cavity 10 is horizontally opened inside each side plate 14; a limiting plate 7 is slidably set in the movable cavity 10; the inner end of the limiting plate 7 near the hub frame 4 is processed into a wedge or cone shape to facilitate insertion; a Y-shaped groove 6 is opened at the corresponding positions of the upper and lower outer walls of the hub frame 4 and the side plate 14; when the hub cover body 1 is installed in place, the inner end of the limiting plate 7 can be inserted into the corresponding Y-shaped groove 6 under the action of driving force, forming a longitudinal insertion lock perpendicular to the hub axis, thereby restricting the tendency of the hub cover body 1 to come off axially.

[0017] To drive the limiting plate 7 and ensure its smooth movement, a pull rod 12 is fixedly connected to the center of the outer end face of the limiting plate 7. The pull rod 12 extends horizontally outward, passing through the rear end wall of the movable cavity 10 and the outer wall of the side plate 14 in sequence, and finally its end is fixedly connected to a pull plate 13 that is easy to operate with fingers. Two helical compression springs are installed between the outer end face of the limiting plate 7 and the inner end face of the movable cavity 10 as elastic elements 11. In the natural state, the elastic force of the spring pushes the limiting plate 7 to move inward, so that it maintains the tendency to insert into the Y-shaped groove 6. In order to guide precisely and prevent the limiting plate 7 from rotating or swaying in the movable cavity 10, two sliders 8 are symmetrically fixed on the upper and lower side walls of the limiting plate 7. Two straight groove slide rails 9 that are precisely matched with the sliders 8 are correspondingly opened on the upper and lower inner walls of the movable cavity 10. The sliders 8 are embedded in the slide rails 9, so that the limiting plate 7 can only move back and forth along a horizontal straight line.

[0018] Working principle: During installation, first align the insert block 2 and insert plate 3 on the inner side of the hub cover body 1 with the corresponding holes and slots on the hub frame 4, so that the hub cover body 1 fits against the hub frame 4. At this time, under the push of the spring 11, the inner wedge end of the limiting plate 7 in the limiting assembly will automatically slide into the Y-shaped groove 6 on the hub frame 4, making a "click" sound and completing the self-locking. Then tighten the central bolt 5. During disassembly, first loosen the bolt 5, and then pull the upper and lower pull plates 13 outwards simultaneously or separately. Through the pull rod 12, overcome the elastic force of the spring 11 to pull the two limiting plates 7 out of the Y-shaped groove 6, and the hub cover body 1 can be removed.

[0019] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
