[0032] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figures 1-9 The nut cover plate fixing structure 100 according to the first embodiment of the present invention is described.

[0034] like Figure 2 、 Figure 3、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the nut cover plate fixing structure 100 according to the embodiment of the first aspect of the present utility model includes: a wheel, a wheel nut 20 and a nut cover plate 30.

[0035] Specifically, a nut mounting hole 10 is formed on the wheel, a wheel nut 20 is arranged in the nut mounting hole 10, and a nut cover plate 30 is formed at one axial end of the nut cover plate 30 (for example, Figure 6 The protective cavity 31 is opened at the lower end (shown in the figure), at least part of the nut cover 30 is arranged in the nut mounting hole 10, the nut cover 30 is covered on the wheel nut 20, the outer peripheral wall of the wheel nut 20 abuts against the inner peripheral wall of the protective cavity 31, and one of the outer peripheral wall of the nut cover 30 and the inner wall of the nut mounting hole 10 is provided with a limiting protrusion 32, and the nut cover 30 abuts against the inner wall of the nut mounting hole 10 through the limiting protrusion 32.

[0036] That is, part of the nut cover 30 may be disposed in the nut mounting hole 10 , or the entire nut cover 30 may be disposed in the nut mounting hole 10 .

[0037] After assembly is completed, when the nut cover 30 is displaced to fall off the wheel nut 20, the wheel nut 20 and the inner walls of the nut mounting hole 10 can exert force on the nut cover 30 from the inside and outside to prevent the nut cover 30 from falling off the wheel nut 20, and the wheel nut 20 and the inner walls of the nut mounting hole 10 can increase the degree of contact between each other and the nut cover 30, thereby improving the reliability of the nut cover 30 on the wheel nut 20.

[0038] Among them, by setting the limiting protrusion 32, during the assembly process, the opening edge of the protective cavity 31 can extend into the gap between the wheel nut 20 and the nut mounting hole 10, and can reduce the resistance during the assembly process, thereby reducing the difficulty of assembly.

[0039] It should be noted that if Figure 1 、 Figure 2 and Figure 4 As shown, the nut mounting hole 10 can be a circular hole or a polygonal hole, and the outer peripheral wall of the nut cover plate 30 can be a cylindrical surface or a polygonal column.

[0040] According to the nut cover plate fixing structure 100 of the embodiment of the first aspect of the present utility model, the reliability of the nut cover plate 30 on the wheel nut 20 can be improved and the assembly difficulty can be reduced.

[0041] In some embodiments of the present invention, Figure 3 and Figure 9As shown, in the direction in which the nut cover 30 is inserted into the nut mounting hole 10 (eg Figure 9 As shown in the figure (from top to bottom), the cross-sectional dimensions of the nut mounting hole 10 gradually decrease. This allows the opening edge of the protective cavity 31 to more easily extend into the gap between the wheel nut 20 and the nut mounting hole 10 during assembly, making it easier to install the nut cover 30 into the nut mounting hole 10. This further reduces the difficulty of assembly. After assembly, the contact between the inner wall of the nut mounting hole 10 and the nut cover 30 is improved, further enhancing the reliability of the nut cover 30 on the wheel nut 20.

[0042] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 7 As shown, the nut cover 30 has an abutment section 33, which is sleeved on the radially outer side of the wheel nut 20. The nut cover 30 abuts the wheel nut 20 and the inner wall of the nut mounting hole 10 through the abutment section 33. The cross-sectional dimension of the abutment section 33 gradually decreases as the nut cover 30 is inserted into the nut mounting hole 10. This makes it easier to insert the nut cover 30 into the nut mounting hole 10 during assembly, further reducing the difficulty of assembly. After assembly is completed, the pressing force of the wheel nut 20 on the nut cover 30 will have a component in the direction away from the nut cover 30, thereby further improving the reliability of the nut cover 30 on the wheel nut 20.

[0043] In some embodiments of the present invention, Figure 2 As shown, the cross-sectional dimensions of the nut mounting hole 10 remain unchanged as the nut cover 30 is inserted into the nut mounting hole 10. The nut cover 30 includes an abutment section 33, which is sleeved radially outward of the wheel nut 20. The nut cover 30 abuts the wheel nut 20 and the inner wall of the nut mounting hole 10 via the abutment section 33. The cross-sectional dimensions of the abutment section 33 remain unchanged as the nut cover 30 is inserted into the nut mounting hole 10. This simplifies the production process of the nut cover 30 and the nut mounting hole 10, reducing production costs.

[0044] In some embodiments of the present invention, Figure 9 As shown, a limiting groove 11 extending axially along the nut mounting hole 10 is formed on the other of the outer peripheral wall of the nut cover 30 and the inner wall of the nut mounting hole 10, and the limiting protrusion 32 abuts against the bottom wall of the limiting groove 11. By providing the limiting groove 11, during the assembly process, the limiting protrusion 32 is gradually installed into the nut mounting hole 10 along the limiting groove 11. The limiting groove 11 limits the travel of the limiting protrusion 32, making the assembly process smoother and further reducing the assembly difficulty.

[0045] In some embodiments of the present invention, Figure 5-Figure 9 As shown, the limiting protrusion 32 is formed on the outer peripheral wall of the nut cover 30, and the limiting groove 11 is formed on the inner wall of the nut mounting hole 10. It is understandable that the side wall of the protective cavity 31 of the nut cover 30 is usually not too thick. Providing the limiting groove 11 on the outer peripheral wall of the nut cover 30 is more difficult to process and will reduce the strength of the nut cover 30, thereby making the nut cover 30 easily damaged. Providing the limiting protrusion 32 on the nut cover 30 and the limiting groove 11 on the inner wall of the nut mounting hole 10 can reduce the production difficulty and reduce structural damage to the nut cover 30.

[0046] In some embodiments of the present invention, Figure 6 As shown, in the direction in which the limiting protrusion 32 protrudes, the two side surfaces of the limiting protrusion 32 in the axial direction of the nut mounting hole 10 extend at an angle relative to each other. Thus, during the process of inserting and removing the nut cover 30 into and from the nut mounting hole 10, the inclination direction of the surface of the limiting protrusion 32 in the axial direction of the nut mounting hole 10 that contacts the nut cover 30 is aligned with the direction of movement of the nut cover 30, thereby further reducing the difficulty of assembly.

[0047] In some embodiments of the present invention, a retaining rib 34 extending axially along the nut cover 30 is formed on the inner circumferential wall of the protective cavity 31. The nut cover 30 abuts the outer circumferential wall of the wheel nut 20 via the retaining rib 34. The provision of the retaining rib 34 improves the abutment between the nut cover 30 and the wheel nut 20. Furthermore, it is understood that the area of the nut cover 30 where the abutment force acts on the retaining rib 34 is relatively small, thereby reducing the probability of damage to the nut cover 30.

[0048] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the limiting rib 34 and the limiting protrusion 32 are opposite each other inside and outside. In this way, the force exerted by the inner wall of the nut mounting hole 10 and the wheel nut 20 on the nut cover 30 can act on the same position on the nut cover 30 from both inside and outside, thereby further improving the contact between the inner wall of the nut mounting hole 10 and the wheel nut 20 and the nut cover 30, and improving the reliability of the nut cover 30 on the wheel nut 20.

[0049] The vehicle according to the embodiment of the second aspect of the present invention includes: the nut cover plate fixing structure 100 according to the embodiment of the first aspect of the present invention.

[0050] According to the vehicle of the second embodiment of the present invention, by providing the nut cover fixing structure 100 according to the first embodiment of the present invention, the probability of the nut cover 30 falling off can be reduced, thereby improving the user experience.
