[0001] The present invention relates to the field of automobile technology, and in particular to a wheel and a vehicle having the same. Background Art

[0002] A car's tires are the only parts of the car that come into contact with the ground. The interface formed by the interaction between the tires and the ground provides force and torque for the car's movement. Therefore, tires are very important to the vehicle's power, safety, and passability.

[0003] In the related art, the inner mounting surface and the outer mounting surface of the high-ventilation hole wheel are generally designed with a stepped transition, which affects the connection effect of the fasteners to a certain extent, and further affects the fasteners to loosen after being installed on the wheel. Summary of the Invention

[0004] The main purpose of the present invention is to provide a wheel and a vehicle having the same, so as to solve the problem of poor connection effect and easy loosening of fasteners in the related art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a wheel is provided, comprising: a rim portion; a spoke portion, arranged inside the rim portion; a plurality of first mounting holes, arranged at intervals on the spoke portion; a second mounting hole, arranged on the spoke portion and located inside the plurality of first mounting holes; a plurality of mounting portions, arranged in one-to-one correspondence with the plurality of first mounting holes, each mounting portion surrounding the corresponding first mounting hole, and each mounting portion including a mounting surface that cooperates with the brake mounting disc, the mounting surface being an inclined surface.

[0006] Furthermore, the mounting surface includes an outer mounting surface and an inner mounting surface, and the outer mounting surface and the inner mounting surface are coplanar.

[0007] Furthermore, the included angles between the outer mounting surface, the inner mounting surface and the brake mounting disc are between 0° and 10°.

[0008] Furthermore, the mounting portion further includes a first recess, which is located on the inner side of the spoke portion and between the outer mounting surface and the inner mounting surface.

[0009] Furthermore, the width of the first recess is between 1 mm and 20 mm.

[0010] Furthermore, the end surface of the rim portion away from the spoke portion is a reference surface, and the distance between the mounting surface and the reference surface gradually increases in the radial direction from the first mounting hole to the second mounting hole.

[0011] Furthermore, the spoke portion further includes a plurality of spokes and a plurality of connecting portions, and each connecting portion is located between two adjacent spokes.

[0012] Furthermore, the spoke includes a second recess, and the first mounting hole is located on the second recess.

[0013] Furthermore, the spoke portion further includes an annular portion, which is located on the first mounting hole and outside the spoke portion.

[0014] According to another aspect of the present invention, a vehicle is provided, comprising a wheel, wherein the wheel is the wheel described above.

[0015] By applying the technical solution of the present invention, the spoke portion is arranged inside the rim portion. A plurality of first mounting holes and a second mounting hole are both arranged on the spoke portion, and the second mounting hole is located inside the plurality of first mounting holes. The plurality of mounting portions are arranged in a one-to-one correspondence with the plurality of first mounting holes, and the mounting portion includes a mounting surface that cooperates with the brake mounting disc, and the mounting surface is an inclined surface. When the wheel is installed, the mounting surface contacts the brake mounting disc, and the fastener connects the wheel to the brake mounting disc. Since the mounting surface is an inclined surface, in the initial state, a portion of the mounting surface contacts the brake mounting disc. As the fastener is continuously tightened, the mounting surface undergoes elastic deformation, so that the inner and outer sides of the mounting surface are completely fitted with the brake mounting disc, and the fitting effect is better, which can more effectively reduce the occurrence of fastener loosening. Therefore, the technical solution of the present application effectively solves the problem of poor connection effect and easy loosening of fasteners in the related art.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

In all examples shown and discussed herein, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] In related art, a wheel has a stepped surface between its inner and outer mounting surfaces. When fasteners connect the wheel to the brake mounting disc, the inner mounting surface doesn't easily come into contact with the brake mounting surface, which can affect the fastener's connection and cause the fastener to loosen.

[0030] In order to solve the above problems, Figures 1 to 5 As shown, in this embodiment, the wheel includes a rim portion 10, a spoke portion 20, a first mounting hole 30, a second mounting hole 40, and a mounting portion 50. The spoke portion 20 is disposed within the rim portion 10. A plurality of first mounting holes 30 are spaced apart on the spoke portion 20. The second mounting hole 40 is disposed on the spoke portion 20 and is located within the plurality of first mounting holes 30. The plurality of mounting portions 50 are disposed in a one-to-one correspondence with the plurality of first mounting holes 30. Each mounting portion 50 surrounds a corresponding first mounting hole 30 and includes an inclined mounting surface 51 that mates with the brake mounting disc.

[0031] In this embodiment, the spoke portion 20 is disposed within the rim portion 10. Multiple first mounting holes 30 and second mounting holes 40 are provided on the spoke portion 20, with the second mounting holes 40 located within the multiple first mounting holes 30. Multiple mounting portions 50 are provided in a one-to-one correspondence with the multiple first mounting holes 30. Each mounting portion 50 includes an inclined mounting surface 51 that mates with the brake mounting disc. During wheel installation, the mounting surface 51 contacts the brake mounting disc, and the fastener connects the wheel to the brake mounting disc. Because the mounting surface 51 is inclined, initially, a portion of the mounting surface 51 contacts the brake mounting disc. As the fastener is tightened, the mounting surface 51 elastically deforms, ensuring that the inner and outer sides of the mounting surface 51 fully and effectively adhere to the brake mounting disc, effectively reducing the risk of fastener loosening. Therefore, the technical solution of this embodiment effectively addresses the poor connection and easy loosening of fasteners in related technologies.

[0032] It should be noted that the above-mentioned mounting surface 51 surrounds the outside of the first mounting hole 30, and the mounting surface 51 is a full circle surface.

[0033] Considering the deformation of the inner and outer mounting surfaces, such as Figures 1 to 5As shown, in this embodiment, the mounting surface 51 includes an outer mounting surface 511 and an inner mounting surface 512, and the outer mounting surface 511 and the inner mounting surface 512 are coplanar. After the wheel is installed, the outer mounting surface 511 first contacts the brake mounting disc. As the fasteners are continuously tightened, the mounting surface 51 is subjected to force and elastic deformation, thereby causing the inner mounting surface 512 and the outer mounting surface 511 to be completely in close contact with the brake mounting disc. Because the mounting surface 51 is an inclined surface, when the mounting surface 51 is elastically deformed, the inner mounting surface 512 and the outer mounting surface 511 exert a force opposite to the tightening direction of the fasteners. This gives the fasteners a pre-tightening force, thereby improving the connection effect of the fasteners and preventing the fasteners from loosening. Compared with the technical solutions in the related art, the technical solution of this embodiment can ensure that the brake mounting disc is in close contact with the inner mounting surface 512 and the outer mounting surface 511. Furthermore, the mounting surface 51 is configured as an inner mounting surface 512 and an outer mounting surface 511 so that the inner mounting surface 512 and the outer mounting surface 511 are more likely to undergo beneficial elastic deformation.

[0034] In order to make the inner and outer mounting surfaces tightly connected with the brake mounting disc and to make the fasteners have pre-tightening force. Figures 1 to 5 As shown, in this embodiment, the angle between the outer mounting surface 511 and the inner mounting surface 512 and the brake mounting disc is 7°. The 7° angle allows the mounting surface 51 to easily undergo elastic deformation, thereby allowing the outer mounting surface 511 and the inner mounting surface 512 to completely fit the brake mounting disc when the fastener is tightened. If the angle between the outer mounting surface 511 and the inner mounting surface 512 and the vertical surface is zero, the fastening effect of the fastener will be affected. The fastener may easily loosen during operation, which may easily cause danger. If the angle between the outer mounting surface 511 and the inner mounting surface 512 and the brake mounting disc is greater than 10°, the inner mounting surface 512 and the outer mounting surface 511 will not be in close contact with the brake mounting disc, which will also affect the connection effect of the fastener. The above-mentioned function can be achieved as long as the angle is between 0° and 10°.

[0035] In order to allow the second mounting surface to have room for deformation and to improve the overall structural strength of the mounting surface. Figures 1 to 5 As shown, in this embodiment, the mounting portion 50 further includes a first recess 52, which is located inside the spoke portion 20 and between the outer mounting surface 511 and the inner mounting surface 512. The provision of the first recess 52 effectively enhances the structural strength of the mounting surface 51 and provides sufficient deformation space for the inner and outer mounting surfaces 512, 511. The first recess 52 protrudes toward the outside of the wheel, making it easier for the inner mounting surface 512 to elastically deform.

[0036] like Figures 1 to 5As shown, in this embodiment, the width of the first recess 52 (the dimension along the circumferential direction of 31) is 5 mm. The width of the first recess 52 of 5 mm can, on the one hand, allow the inner mounting surface 512 to have a better deformation space. On the other hand, it can adapt to the size of the mounting surface 51. If the width of the first recess 52 is greater than 20 mm, the area of ​​the inner mounting surface 512 and the outer mounting surface 511 will be smaller, and the contact area with the brake mounting disc will be smaller, which will affect the connection effect. If the width of the first recess 52 is less than 1 mm, the mounting surface 51 will not easily deform, and it will be difficult to achieve the effect of preload. Of course, the above-mentioned advantages can be achieved as long as the width of the first recess 52 is between 1 mm and 20 mm. The specific value of the width of the first recess 52 needs to be specifically set according to the size of the mounting surface 51.

[0037] In order to facilitate better or beneficial elastic deformation of the inner mounting surface, such as Figures 1 to 5 As shown, in this embodiment, the end surface of the rim 10 distal to the spoke 20 serves as a reference surface. The distance between the mounting surface 51 and the reference surface gradually increases radially from the first mounting hole 30 to the second mounting hole 40. Horizontally, the outer mounting surface 511 is higher than the inner mounting surface 512. The outer mounting surface 511 contacts the brake mounting disc first, followed by the inner mounting surface 512. The inner mounting surface 512 is located closer to the center of the wheel, which facilitates better or beneficial elastic deformation.

[0038] In order to improve the overall structural strength of the wheel, Figure 1 、 Figure 3 、 Figure 6 as well as Figure 7 As shown, in this embodiment, the spoke portion 20 further includes a plurality of spokes 21 and a plurality of connecting portions 22, each of which is located between two adjacent spokes 21. The arrangement of multiple spokes 21 effectively enhances the structural strength of the wheel. Furthermore, the ventilation holes between adjacent spokes 21 provide improved heat dissipation, allowing for easier dissipation of brake heat during vehicle operation, reducing system temperatures and improving mileage. The provision of connecting portions 22 connects the multiple spokes 21, enhancing the structural strength of the spokes 21 and, consequently, indirectly improving the overall structural strength of the wheel.

[0039] In order to improve the structural strength of the spokes, such as Figure 1 、 Figure 3 、 Figure 6 as well as Figure 7 As shown, in this embodiment, the spoke 21 includes a second recess 211, and the first mounting hole 30 is located on the second recess 211. The second recess 211 has a simple structure and is easy to set up, which can improve the structural strength of the spoke 21 and make the spoke 21 less likely to deform.

[0040] like Figure 6 and Figure 7 As shown, in this embodiment, the spoke portion 20 further includes an annular portion 23, which is located on the first mounting hole 30 and outside the spoke portion 20. The annular portion 23 has a simple structure, and the fastener can be in close contact with the annular portion 23, thereby indirectly ensuring the connection effect of the fastener.

[0041] According to another aspect of the present application, a vehicle is provided, including a wheel, wherein the wheel is the aforementioned wheel. The aforementioned wheel has a better connection to the vehicle, and the fasteners are less likely to loosen, thereby ensuring the service life of the wheel. Therefore, a vehicle equipped with this wheel also has the aforementioned advantages.

[0042] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
