Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and specifically to a wheel hub cover mounting structure that is easy to install and remove. Background Technology

[0002] Wheel caps are typically installed on the outside of vehicle wheel rims to cover the connection between the wheel rim and the axle, preventing mud, sand, and gravel from entering the wheel rim cavity, thus serving a protective and decorative purpose. In existing technology, wheel caps are usually reliably fixed to the wheel rim using bolts. This method requires pre-drilling bolt holes during manufacturing, increasing production steps and costs. Furthermore, the secure fixing makes bolt removal difficult, especially after prolonged exposure to rain and mud, leading to cumbersome maintenance and replacement procedures and increased maintenance costs.

[0003] Among them, the existing patent with publication number CN218140862U discloses a hubcap that is easy to install. It achieves a decorative function without changing the hub structure, and the installation and fixing do not require bolts, which facilitates installation and disassembly. Although this solution simplifies the installation method, it still has some shortcomings. On the one hand, the fastening method is relatively simple, relying on snap-fit ​​without further sealing and fixing; on the other hand, disassembly is relatively inconvenient. As can be seen from the attached drawings, the hubcap is basically semi-enclosed, so the force-bearing area of ​​the disassembly groove on the outer wall of the hubcap should be small, which is not conducive to forceful disassembly. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a wheel hub cover installation structure that is easy to install and remove. While ensuring that the wheel hub cover is securely installed with the wheel hub, it simplifies the steps of installing and removing the wheel hub cover.

[0005] To solve the above problems, the present invention adopts the following solution: A convenient wheel hub cover mounting structure includes a detachably fitted wheel hub and a wheel hub cover. The wheel hub cover is installed on the outside of the wheel hub and includes a locking ring that engages with the wheel hub and a baffle plate that is detachably installed with the locking ring. The locking ring is ring-shaped and has an operating hole in the middle for easy removal from the wheel hub. The operating hole has space to accommodate two hands. The baffle plate is installed at the operating hole and can completely cover the operating hole. The locking ring has multiple sets of latching components evenly distributed along its circumference. The outer peripheral wall of the latching components fits tightly against the inner wall of the cavity on the outer side of the wheel hub.

[0006] Furthermore, the clamping ring is provided with a plurality of mounting holes at equal intervals along the circumference of the operating hole, and the baffle plate is provided with elastic cards at equal intervals along its circumference that correspond one-to-one with the plurality of mounting holes. The elastic cards have hook portions to be able to be engaged in the mounting holes. Furthermore, the inner circumferential wall of the hub cavity is inclined from the edge to the center, and the inclined shell wall of the cavity has a certain elasticity, allowing the snap-fit ​​assembly to fit elastically against the inner wall of the cavity in an inclined manner. This design ensures that when the snap-fit ​​assembly is snapped onto the inner wall of the cavity, the inclined shell wall of the cavity can provide a certain elastic wrapping force to the snap-fit ​​assembly, thereby ensuring stable snap-fitting.

[0007] Furthermore, the buckle assembly has multiple elastic fastening pieces spaced apart, one of which has a guide protrusion that protrudes outward to guide the buckle assembly into the wheel hub cavity, thereby improving installation convenience.

[0008] Furthermore, the elastic fastening piece is provided in three parts, with the elastic fastening piece having a guide protrusion located in the middle.

[0009] Furthermore, the outer wall of the elastic fastening piece is provided with a sealing strip to further increase the friction between the buckle assembly and the inner wall of the cavity, thereby improving the installation stability of the hub cover.

[0010] Furthermore, the sealing strip is disposed on the elastic fastening plates located on both sides.

[0011] Because the middle elastic fastener has a guide protrusion, it will form a certain gap with the inner wall of the cavity, making it unable to fit as tightly as the elastic fasteners on both sides. Therefore, the sealing strip in the middle part can be omitted, saving some production costs. In addition, when it is difficult to remove the hub cover, a tool can be used, which can be easily inserted into the middle part to assist in the removal.

[0012] Furthermore, multiple sets of the aforementioned snap-fit ​​components are integrally formed, with the shell wall between each pair of adjacent snap-fit ​​components being recessed so that when engaging with the wheel hub, the recessed portion separates from the inner wall of the cavity.

[0013] The above solution improves the overall support strength of the buckle assembly through the one-piece molding design, and avoids the problem of the buckle assembly being circular in shape, which would cause the outer wall of the buckle assembly to be in close contact with the inner wall of the cavity, thus avoiding inconvenience in disassembly and assembly.

[0014] Furthermore, the hubcap has a semi-enclosed structure, which can form a sealed cavity with the cavity on the outward side of the hub. This completely prevents mud, sand, gravel, and other debris from entering the cavity of the hub, avoiding damage to the axle end.

[0015] Furthermore, the hubcap is made of thermally modified polyamide, which is achieved by adding highly thermally conductive fillers to the base nylon, resulting in good strength, elasticity, and heat dissipation performance. This ensures that the hubcap has sufficient strength to guarantee a stable connection, sufficient elasticity to achieve a flexible snap-fit ​​with the hub, and sufficient heat dissipation performance to improve the heat dissipation effect of the hub.

[0016] The beneficial effects of this utility model are as follows: In this utility model, the hub cover is set as a detachable double-layer structure. One part is a clamping ring, which can be firmly clamped into the cavity of the hub by the buckle assembly on it. The other part is a baffle plate, which can be detachably installed with the clamping ring and can block the operation hole on the clamping ring used to assist in disassembly. Therefore, on the one hand, the hubcap can be semi-enclosed, which can completely prevent mud, sand and gravel from entering the cavity of the hub and avoid damage to the axle end; on the other hand, when it is necessary to remove the hubcap, the baffle plate can be removed by using a suction cup or other tools, and then the hand can be inserted into the operating hole to apply force to remove the retaining ring, making disassembly convenient and quick.

[0017] During installation, simply apply force to clamp the retaining ring into the hub cavity, and then clamp the elastic clip of the baffle plate into the mounting hole. Compared with bolt fixing, this installation method greatly improves the efficiency of disassembly and assembly, and also avoids the difficulty of disassembly that may be caused by corrosion of the connection parts by rainwater, mud and sand.

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other. Example

[0021] refer to Figures 1-5 This embodiment provides a convenient hubcap mounting structure for easy disassembly and assembly, applied to the wheels of all-terrain vehicles. By setting a snap-fit ​​mounting component 23, it improves the installation tightness and ease of operation between the hubcap 20 and the hub 10, thereby replacing the more cumbersome bolt fixing structure. At the same time, the hubcap 20 is set as a double-layer detachable structure, so as to provide an operation hole 211 for easy hand force application when the hubcap 20 needs to be removed, avoiding the inconvenience of disassembly due to excessive tightness. Under normal conditions, it can completely cover the cavity 11 on the outward side of the hub 10, preventing rainwater, mud, sand and other substances from entering the cavity 11 and causing damage to the axle end.

[0022] refer to Figure 1 The mounting structure includes a detachable wheel hub 10 and a wheel hub cap 20. The wheel hub cap 20 is semi-enclosed and installed on the outside of the wheel hub 10. It can form a sealed cavity with the cavity 11 on the outward side of the wheel hub 10, thus completely preventing mud, sand, gravel, etc. from entering the cavity 11 of the wheel hub 10 and avoiding damage to the axle end; see reference. Figure 2 The hubcap 20 adopts a double-layer detachable structure, including a clamping ring 21 that is detachably engaged with the hub 10 and a baffle plate 22 that is detachably installed with the clamping ring 21. The clamping ring 21 is ring-shaped and has an operation hole 211 in the middle for easy removal from the hub 10. The operation hole 211 has space to accommodate two hands. The baffle plate 22 is detachably installed at the operation hole 211 and can completely cover the operation hole 211.

[0023] Specifically, refer to Figure 2 The clamping ring 21 has a plurality of mounting holes 212 evenly spaced along the circumference of the operating hole 211. The baffle plate 22 has elastic clips 221 that correspond one-to-one with the plurality of mounting holes 212 evenly spaced along its circumference. The elastic clips 221 have hook portions that can be engaged in the mounting holes 212 (the hook portions are not marked in the figure, but can be seen in the figure). Figure 2 In this embodiment, both the mounting hole 212 and the elastic card 221 are provided with six.

[0024] To achieve a secure connection between the locking ring 21 and the cavity 11 of the hub 10. (Reference) Figure 2 The circular end face of the clamping ring 21 has multiple sets of buckling components 23 evenly distributed along its circumference. The outer peripheral wall of the buckling component 23 is tightly fitted with the inner wall of the cavity 11 on the outward side of the hub 10. In this embodiment, six sets of buckling components 23 are provided.

[0025] refer to Figures 4-5The inner circumferential wall of the cavity 11 of the hub 10 is inclined from the edge to the center, and the inclined shell wall of the cavity 11 has a certain elasticity. Therefore, the snap-fit ​​assembly 23 fits into the inner wall of the cavity 11 at an inclined position. This arrangement allows the inclined shell wall of the cavity 11 to exert an inclined wrapping force on the snap-fit ​​assembly 23 when it is snapped into the inner wall of the cavity 11. Compared with the vertical snap-fit, this structure can ensure a more stable snap-fit.

[0026] Specifically, refer to Figure 3 The buckle assembly 23 has three elastic fastening pieces 231 spaced apart. The middle elastic fastening piece 231 has a guide protrusion 232 that protrudes outward to guide the buckle assembly 23 into the cavity 11 of the wheel hub 10, thereby improving the ease of installation.

[0027] Further, refer to Figure 3 , Figure 5 The outer wall of the elastic fastening piece 231 is provided with a sealing strip 233, which is used to further improve the friction between the buckle assembly 23 and the inner wall of the cavity 11, and improve the installation stability of the hub cover 20.

[0028] Preferably, refer to Figure 3 The sealing strip 233 is disposed on the elastic fasteners 231 located on both sides. Since the middle elastic fastener 231 has a guide protrusion 232, the elastic fastener 231 will form a certain gap with the inner wall of the cavity 11, so that it cannot be tightly attached to the inner wall of the cavity 11 like the elastic fasteners 231 on both sides. Therefore, the sealing strip 233 in the middle part can be omitted, saving a certain production cost. In addition, when it is difficult to remove the hub cover 20, a tool can be used. At this time, it is convenient to insert the tool into the middle elastic fastener 231 with the gap to assist in the removal.

[0029] Further, refer to Figure 2 The multiple sets of snap-fit ​​components 23 are integrally formed, which can improve the overall support strength of the snap-fit ​​components. The shell wall between each two adjacent snap-fit ​​components 23 is recessed so that when it is snapped with the hub 10, the recessed part separates from the inner wall of the cavity 11. This avoids the snap-fit ​​components 23 being circular in shape, so that their outer walls are all in close contact with the inner wall of the cavity 11, which would make disassembly and assembly inconvenient. (This recessed design is not marked in the figure, but its structure can be referred to.) Figure 2 ).

[0030] In this embodiment, the hubcap 20 is made of thermally conductive modified polyamide, which is achieved by adding highly thermally conductive fillers to the base nylon, resulting in good strength, elasticity, and heat dissipation performance. This ensures that the hubcap 20 has sufficient strength to guarantee a stable connection, sufficient elasticity to allow for a snap-fit ​​connection with the hub 10, and sufficient heat dissipation performance to improve the heat dissipation effect of the hub 10.

[0031] The specific operation process of this embodiment is as follows: When the hub cap 20 needs to be installed on the hub 10, the multiple sets of snap fasteners 23 of the clamping ring 21 can be embedded into the circular cavity 11 of the hub 10 first, and then the clamping ring 21 can be firmly clamped to the inner wall of the cavity 11 by pressing. Then, the elastic clip 221 of the baffle plate 22 can be clamped into the mounting hole 212 by pressing. During this pressing process, the clamping steps of the clamping ring 21 are also repeated, which can further ensure the clamping firmness of the clamping ring 21. In actual installation, the clamping order of the two can be changed according to convenience. When it is necessary to remove the hub cap 20 from the hub 10, first use a suction cup or other tools to remove the baffle plate 22, then insert your hand into the operating hole 211 and apply force to remove the retaining ring 21.

[0032] Although other tools were used to assist in the disassembly process, such as suction cup tools to remove the bolts directly under negative pressure, or using a screwdriver to pry the elastic card 221 out of the mounting hole 212, the disassembly operation in this embodiment is more convenient and faster than the bolt fixing method, which involves removing the bolts one by one.

[0033] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
