[0022] More and more car models on the market are now using a "double tire" configuration (different front and rear wheel / tire specifications and sizes, but the same wheel design). However, this type of tire configuration with different front and rear specifications is prone to problems such as mixing front and rear tires during tire assembly and disassembly. Furthermore, it can easily lead to incorrect assembly of the front / rear tire assemblies during after-sales maintenance and tire replacement. Incorrect assembly of the front and rear tires can result in degraded vehicle performance and may even pose safety risks.

[0023] This invention proposes a vehicle designed to improve the problem of incorrect assembly of the front / rear wheel tire assemblies when installing mismatched tires in existing vehicles that require a mismatched tire configuration.

[0024] Please see Figures 1 to 2 In one embodiment of the present invention, the automobile includes a front wheel assembly 1 and a rear wheel assembly 2. The front wheel assembly 1 includes a front wheel 11 and a front brake assembly 12. The front brake assembly 12 is disposed at the front tire mounting location of the automobile for mounting the front wheel 11. The front wheel 11 is provided with a first foolproof structure 13. The rear wheel assembly 2 includes a rear wheel 21 and a rear brake assembly. The rear brake assembly is disposed at the rear tire mounting location of the automobile for mounting the rear wheel 21. The size of the rear wheel 21 is different from that of the front wheel 11. The rear wheel 21 is provided with a second foolproof structure 22. The first foolproof structure 13 and the second foolproof structure 22 are different.

[0025] In the technical solution of the present invention, by providing the first anti-mistake structure 13 on the front wheel 11 and the second anti-mistake structure 22 on the rear wheel 21, and by providing the first anti-mistake structure 13 and the second anti-mistake structure 22 differently, it is easy to distinguish between the front wheel 11 which is set at the front tire mounting position and the rear wheel 21 which is set at the rear tire mounting position, thereby avoiding the problem of incorrect assembly of the front / rear wheel tire 7 assembly when installing mismatched tires.

[0026] It should be noted that the appendix Figure 1 Taking the front wheel 11 as an example, the schematic diagram shows its structure. The location of related components of the rear wheel 21 is shown in the attached diagram. Figure 1 That's all.

[0027] Please see Figure 3 , Figure 4 , Figure 5 and Figure 7In an embodiment of the present invention, the front wheel 11 includes a first rim 111, and the rear wheel 21 includes a second rim 211; the first anti-misalignment structure 13 includes a first anti-misalignment protrusion 131 disposed on the first rim 111; the second anti-misalignment structure 22 includes a second anti-misalignment protrusion 221 disposed on the second rim 211; the first anti-misalignment protrusion 131 and the second anti-misalignment protrusion 221 are configured with different shapes and / or numbers. That is, by setting the first anti-misalignment structure 13 as the first anti-misalignment protrusion 131 and the second anti-misalignment structure 22 as the second anti-misalignment protrusion 221, and by setting the first anti-misalignment protrusion 131 and the second anti-misalignment protrusion 221 with different shapes and / or numbers, it is convenient to directly observe or touch to determine whether the wheel to be assembled is the front wheel 11 or the rear wheel 21 before assembly, thereby avoiding the problem of incorrect assembly of the front / rear wheel tire 7 assembly.

[0028] It should be noted that the present invention does not limit the specific form of the first foolproof structure 13 and the second foolproof structure 22. For example, in another embodiment of the present invention, the first foolproof structure 13 is configured as a groove, and the second foolproof structure 22 is also configured as a groove. Or, in yet another embodiment of the present invention, the first foolproof structure 13 is configured as a protrusion, and the second foolproof structure 22 is configured as a groove. In short, regardless of the form, as long as the first foolproof structure 13 and the second foolproof structure 22 can be distinguished by direct observation or touch before assembly, the present invention does not impose any restrictions on this.

[0029] In an embodiment of the present invention, the outer rim of the first rim 111 is provided with the first anti-mistake protrusion 131; the outer rim of the second rim 211 is provided with the second anti-mistake protrusion 221. That is, by providing the first anti-mistake protrusion 131 on the outer rim of the first rim 111, the front wheel 11 can be directly observed and identified, and the rear wheel 21 is similarly identified. In another embodiment of the present invention, the inner rim of the first rim 111 is provided with the first anti-mistake protrusion 131; the inner rim of the second rim 211 is provided with the second anti-mistake protrusion 221. In this embodiment, by providing the first anti-mistake protrusion 131 on the inner rim of the first rim 111, even after the tire 7 is mounted on the outer rim of the first rim 111, it can still be identified as the front wheel 11 by the first anti-mistake protrusion 131 on the inner rim of the first rim 111, and the rear wheel 21 is similarly identified. It should be noted that the above-mentioned scheme of providing the first anti-mistake protrusion 131 on the outer rim and the inner rim can be used separately or simultaneously, and the present invention does not limit this.

[0030] It should be noted that the present invention does not limit the shape of the first anti-mistake protrusion 131. For example, it can be in the form of a dot-shaped protrusion, which distinguishes the front wheel 11 and the rear wheel 21 by the height or arrangement of the dot-shaped protrusion. It can also be an extended strip-shaped protrusion. Furthermore, the present invention does not limit the extension trajectory of the strip-shaped protrusion. In the embodiments of the present invention, the first anti-mistake protrusion 131 is arranged in a ring; the second anti-mistake protrusion 221 is arranged in a ring. That is to say, by arranging the first anti-mistake protrusion 131 in a ring, it can be directly observed from any angle, which is convenient for observation. The same applies to the ring arrangement of the second anti-mistake protrusion 221.

[0031] In other embodiments of the present invention, the first anti-mistake protrusion 131 extends axially along the first rim 111, and the first rim 111 has a plurality of protrusions spaced apart in the circumferential direction; the second anti-mistake protrusion 221 extends axially along the second rim 211, and the second rim 211 has a plurality of protrusions spaced apart in the circumferential direction. In this embodiment, the first anti-mistake protrusion 131 or the second anti-mistake protrusion 221 can also be directly observed from multiple angles, and through reasonable arrangement, the first anti-mistake protrusion 131 and the second anti-mistake protrusion 221 can be observed from any angle.

[0032] It should be noted that when the first anti-mistake protrusion 131 and the second anti-mistake protrusion 221 are arranged in a ring, the present invention does not limit the extension path and number of the first anti-mistake protrusion 131 and the second anti-mistake protrusion 221. For example, in an embodiment of the present invention, the outer and inner rings of the first rim 111 are each provided with one first anti-mistake protrusion 131; the outer and inner rings of the second rim 211 are each provided with two second anti-mistake protrusions 221. In this embodiment, by providing one first anti-mistake protrusion 131 on both the outer and inner rings of the first rim 111 and two second anti-mistake protrusions 221 on both the outer and inner rings of the second rim 211, the first tire 7 located at the front tire mounting location and the second tire 7 located at the rear tire mounting location are distinguished. It should be noted that this embodiment is distinguished only by the number of the first anti-mistake protrusion 131 and the second anti-mistake protrusion 221, and does not limit their extension path. For example, in the embodiment of the present invention, neither the first anti-mistake protrusion 131 nor the second anti-mistake protrusion 221 is bent. In other embodiments of the present invention, the first anti-mistake protrusion 131 and the second anti-mistake protrusion 221 may be bent while extending circumferentially, and distinguished by their extension trajectory. The present invention does not limit how they are specifically set.

[0033] Please refer to further information. Figure 6 ,Figure 8 , Figure 9 and Figure 10 In the above embodiments, the first anti-mistake structure 13 and the second anti-mistake structure 22 can only distinguish the front wheel 11 and the rear wheel 21 before assembly. However, it is still possible for the front and rear wheels to be mistakenly installed due to the negligence of the assembler. To prevent this from happening, in the embodiments of the present invention, the front wheel 11 includes a front wheel body 112 and a first flange 113. The first flange 113 is installed in the middle of the front wheel body 112. The first flange 113 is provided with a plurality of first positioning holes 3 and first anti-mistake holes 132. The front brake assembly 12 includes a first brake disc 121. The first brake disc 121 is used to be installed on the front axle of the vehicle. The first brake disc 121 is provided with a plurality of first positioning bolts 4 and first mating parts 5. The first positioning bolts 4 are used to mate with the first positioning holes 3 and the first mating parts 5 are used to mate with the first positioning holes 3. The rear wheel 21 includes a rear wheel body 212 and a second flange 213, which is installed in the middle of the rear wheel body 212. The second flange 213 is provided with a plurality of second positioning holes 6 and a second anti-fool hole 222. The rear brake assembly includes a second brake disc, which is used to be installed on the rear axle of the vehicle. The second brake disc is provided with a plurality of second positioning bolts and a second mating part. The second positioning bolts are used to mate with the second positioning holes 6, and the second mating part is used to mate with the second anti-fool hole 222. The first anti-fool hole 132 and the second anti-fool hole 222 are configured to differ in position, shape and / or size. The first anti-fool structure 13 includes the first anti-fool hole 132, and the second anti-fool structure 22 includes the second anti-fool hole 222.

[0034] In the above embodiment, by setting the first anti-mistake structure 13 as the first anti-mistake hole 132 and the second anti-mistake structure 22 as the second anti-mistake hole 222, and simultaneously providing a first mating part 5 on the first brake disc 121 to mate with the first anti-mistake hole 132, and a second mating part on the second brake disc to mate with the second anti-mistake hole 222, the positions, shapes, and / or dimensions of the first anti-mistake hole 132 and the second anti-mistake hole 222 are different. Even if the front and rear wheels are mistakenly installed during assembly, the differences in positions, shapes, and / or dimensions of the first anti-mistake hole 132 and the second mating part will prevent them from mating, and the second anti-mistake hole 222 will prevent them from mating with the first mating part 5. Thus, the front wheel 11 or the rear wheel 21 cannot be successfully assembled, further preventing the occurrence of misassembly of the front and rear wheels. It should be noted that in this embodiment, the first positioning bolt 4 and the first positioning hole 3 are used to position and install the front wheel 11, and the second positioning bolt and the second positioning hole 6 are used to position and install the rear wheel 21. The present invention does not limit the specific dimensions, and the specific structure can refer to the conventional settings in the field.

[0035] In an embodiment of the present invention, the distance from the first anti-misfit hole 132 to the axis of the front wheel body 112 is L1, and the distance from the second anti-misfit hole 222 to the axis of the rear wheel body 212 is L2, where L1 and L2 are not equal. That is, the present invention sets a size difference between L1 and L2 to prevent misassembly of the front and rear wheels. In another embodiment of the present invention, the first anti-misfit hole 132 is a polygonal hole, and the first mating part 5 is correspondingly set as a protrusion that can only mate with the shape of the first anti-misfit hole 132; the second anti-misfit hole 222 is a circular hole, and the second mating part is correspondingly set as a protrusion that can only mate with the shape of the second anti-misfit hole 222. In this embodiment, the shape difference between the first anti-misfit hole 132 and the second anti-misfit hole 222 prevents misassembly of the front and rear wheels.

[0036] It should be noted that the present invention does not impose specific restrictions on the size relationship between L1 and L2. For example, L1 can be greater than L2 or L1 can be less than L2. The present invention does not impose any restrictions on this.

[0037] In an embodiment of the present invention, multiple first positioning holes 3 and multiple first anti-fool holes 132 are provided, and the first positioning holes 3 and the first anti-fool holes 132 are staggered circumferentially; multiple second positioning holes 6 and multiple second anti-fool holes 222 are provided, and the second positioning holes 6 and the second anti-fool holes 222 are staggered circumferentially. In this embodiment, the staggered arrangement of the first positioning holes 3 and the first anti-fool holes 132 ensures the assembly strength of the front wheel 11 to the front brake assembly 12, and the staggered arrangement of the second positioning holes 6 and the second anti-fool holes 222 ensures the assembly strength of the rear wheel 21 to the rear brake assembly. It should be noted that the present invention does not limit the number of the first anti-fool holes 132 and the second anti-fool holes 222. In an embodiment of the present invention, five first anti-fool holes 132 and five first positioning holes 3 are provided, and five second anti-fool holes 222 and five second positioning holes 6 are provided.

[0038] In an embodiment of the present invention, the first mating part 5 includes a first mating protrusion 51 protruding from the first brake disc 121. At least two first mating protrusions 51 are provided, and each first mating protrusion 51 corresponds to the first anti-fool hole 132. The second mating part includes a second mating protrusion protruding from the second brake disc. At least two second mating protrusions are provided, and each second mating protrusion corresponds to the second anti-fool hole 222. That is, because the first mating protrusion 51 protrudes from the first brake disc 121, it can achieve the function of positioning and installation. Furthermore, since the positioning and installation of the front wheel 11 is mainly achieved by the cooperation of the first positioning hole 3 and the first positioning bolt 4, it does not affect its structural strength. Therefore, providing at least two first mating protrusions 51 reduces production costs and improves structural strength. The arrangement of the second mating protrusions is similar and will not be described in detail.

[0039] In the above embodiments, since the cooperation between the first anti-misalignment hole 132 and the first mating protrusion 51 enables positioning and installation, when the first mating protrusion 51 and the second mating protrusion 52 are arranged adjacently, it may affect the balance of their overall strength. To prevent this, in the embodiments of the present invention, two first mating protrusions 51 are provided, and at least one first anti-misalignment hole 132 is provided between the two first anti-misalignment holes 132 corresponding to the two first mating protrusions 51; two second mating protrusions are provided, and at least one second anti-misalignment hole 222 is provided between the two second anti-misalignment holes 222 corresponding to the two second mating protrusions. That is, by providing at least one first anti-misalignment hole 132 between the two first anti-misalignment holes 132 corresponding to the two first mating protrusions 51, the cooperation strength between the first anti-misalignment hole 132 and the first mating protrusion 51 is more even, and the structural arrangement is more reasonable; the arrangement of the second anti-misalignment hole 222 and the second mating protrusion is similar, and will not be described in detail here.

[0040] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
