Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to an assembly structure of a decorative part and a hub. BACKGROUND

[0002] The automobile hub is a component of the wheel. The hub needs to be holed for fixation. However, the form, size and position of the hub hole determine the wind resistance coefficient during the automobile driving process. If the hub hole is too large, the driving wind resistance coefficient during the automobile driving process will increase, which will be converted into an increase in the use of energy. If the hub hole is too small, the weight of the hub will increase, the cost will increase, and the brake heat accumulation during the automobile driving process will cause a hidden danger to the service life and safety of the automobile. Therefore, in the existing scheme, a decorative part is used to close the hub hole to reduce the influence of the hole on the wind resistance, so as to ensure the best hole rate and improve the performance of the hub.

[0003] However, the existing decorative part has the following defects: first, the decorative part is bolted on the hub, although the strength of the connection structure is sufficient, the bolt increases the overall mass (or understood as the unsprung mass) of the hub, which has a great negative impact on the driving quality and driving safety, and the assembly process is more troublesome; second, the decorative part is directly clamped on the hub, but with the driving of the automobile, the clamping part is prone to shaking, abnormal sound and even falling off; third, the decorative part is generally made of plastic, and the clamping part is also made of plastic, which is prone to failure and loss of clamping force, and falls off from the hub; fourth, since the hub is generally pressure-cast, the tolerance of the clamping hole is large, and the tolerances of multiple clamping holes are accumulated together, which causes each decorative part to be unable to completely align with the clamping port on the hub, resulting in its inability to be clamped and installed, and even if it is forcibly clamped, the clamping part will be subjected to a large lateral force, causing it to break.

[0034] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0035] Please refer to Figures 1-7 The present application discloses an assembly structure of a decorative member and a hub, which is used for mounting the decorative member 100 on the hub 300, wherein the hub 300 has a first clamping portion 310, and the decorative member 100 is provided with a first clamping member 110, and the first clamping member 110 comprises at least two first clamping portions 111, each of which abuts against the inner wall of one of the first clamping portions 310 so that the first clamping member 110 is clamped into the first clamping portion 310.

[0036] The assembly structure further comprises a second clamping member 200, which is clamped into the first clamping member 110 to exert a force on the first clamping portion 111 in a direction towards the inner wall of the first clamping portion 310.

[0037] Specifically, the present application mounts the decorative member 100 on the hub 300 in the form of clamping, and adds a second clamping member 200, which is clamped into the first clamping member 110 to exert a force on the first clamping portion 111 in a direction towards the inner wall of the first clamping portion 310, thereby increasing the force of the first clamping portion 111 on the inner wall of the first clamping portion 310, achieving the enhancement of the clamping force, and preventing the decorative member 100 from falling off during the driving of the automobile. Moreover, only the second clamping member 200 with a very small mass is added, and the unsprung mass is basically not increased.

[0038] Further, since the second clamping part 200 is clamped into the first clamping part 110, the first clamping part 110 is expanded, and the size range of the hole that can be clamped is larger, and when the first clamping interface 310 on the hub 300 has a large tolerance, the first clamping part 110 can also be clamped therein, and after the first clamping part 110 is clamped, there is no problem of transverse stress causing breakage.

[0039] Further, when the first clamping part 110 fails, the second clamping part 200 exerts a force on the first clamping part 110, so that the first clamping part 110 can continue to be clamped in the first clamping interface 310, preventing the decorative part 100 from shaking, making noise, or even falling after the first clamping part 110 fails.

[0040] In summary, compared with the bolt connection form, the connection mode of the present application can improve the driving quality, enhance the driving safety, and reduce the assembly difficulty and cost; compared with the direct clamping form, the connection mode of the present application can enhance the connection strength, prevent the first clamping part 110 from failing and falling, and reduce the tolerance requirement for the plurality of first clamping interfaces 310 on the hub 300.

[0041] Further, the first clamping part 110 includes two first clamping portions 111, and a second clamping interface 112 is formed between the two first clamping portions 111, and the second clamping part 200 is clamped into the second clamping interface 112.

[0042] Specifically, as shown in Figure 2 two first clamping portions 111 are arranged in a V shape or a U shape, and the two first clamping portions 111 are on both sides and have elastic forces away from each other, so that the two first clamping portions 111 can abut against the inner wall of the first clamping interface 310 outward, and then be clamped with the first clamping interface 310.

[0043] Further, the second clamping part 200 includes two second clamping portions 210, and each second clamping portion 210 is in interference fit with a first clamping portion 111.

[0044] After the second clamping part 200 is clamped into the first clamping part 110, the two second clamping portions 210 also have elastic forces away from each other, so that the second clamping portion 210 is in interference fit with the first clamping portion 111, realizes clamping, so that the second clamping portion 210 exerts a force on the first clamping portion 111 towards the outside, and then enhances the clamping strength of the first clamping part 110 and the hub 300.

[0045] Further, the first clamping piece 110 comprises a body 116, and one first clamping part 111 is arranged on each side of the body 116, and a second clamping interface 112 is formed between each first clamping part 111 and the body 116, and one second clamping piece 200 is clamped in each second clamping interface 112.

[0046] Specifically, as shown in the drawings, two first clamping parts 111 are arranged on the two sides of the body 116, and a second clamping interface 112 is formed between the first clamping part 111 and the body 116, and the second clamping piece 200 is clamped in the second clamping interface 112, so that the second clamping part 210 can exert an outward force on the first clamping part 111, thereby enhancing the clamping strength of the first clamping piece 110 and the hub 300. Figure 3

[0047] Further, the second clamping piece 200 comprises two second clamping parts 210, one of which is in interference fit with the body 116, and the other is in interference fit with the first clamping part 111.

[0048] When the second clamping piece 200 is clamped in the second clamping interface 112, the two second clamping parts 210 have elastic force away from each other, so that the second clamping part 210 is in interference fit with the first clamping part 111, realizing clamping, so that the second clamping part 210 exerts an outward force on the first clamping part 111, thereby enhancing the clamping strength of the first clamping piece 110 and the hub 300.

[0049] Further, the first clamping piece 110 is further provided with two abutting parts 115 at one end away from the first clamping part 111, and when the first clamping part 111 is clamped in the first clamping interface 310, the abutting part 115 abuts against the surface of the hub 300.

[0050] The abutting part 115 is arranged, and when the first clamping part 111 of the first clamping piece 110 is clamped in the first clamping interface 310, the abutting part 115 abuts against the surface of the hub 300, so that the first clamping piece 110 cannot continue to enter the first clamping interface 310 or exit the first clamping interface 310, thereby realizing the clamping of the decorative piece 100 and the hub 300.

[0051] Further, the first clamping interface 310 has a first entering end and a first clamping end, and the width of the first clamping interface 310 gradually decreases from the first entering end to the first clamping end, and the first clamping end is outwardly bent to form a first clamping surface 320.

[0052] ​The first clamping part 111 has a second entering end and a second clamping end, the width of the first clamping part 111 gradually increases from the second entering end to the second clamping end, and the second clamping end is inwardly bent to form a second clamping surface 113, which can abut against the first clamping surface 320.

[0053] The width of the first clamping interface 310 gradually decreases from the first entering end to the first clamping end, so that the inner wall of the first clamping interface 310 forms a first guide slope; the width of the first clamping part 110 gradually increases from the second entering end to the second clamping end, so that the outer wall of the first clamping part 110 forms a second guide slope. During the process of clamping the first clamping part 110 into the first clamping interface 310, the first clamping part 110 does not need to be completely aligned with the first clamping interface 310, but only needs to be roughly aligned and the first guide slope and the second guide slope abut against each other, the two guide slopes can slide relative to each other and gradually make the first clamping part 110 completely aligned with the first clamping interface 310, and then the clamping can be realized by pushing the first clamping part 110, which reduces the difficulty of clamping. After clamping, the first clamping surface 320 and the second clamping surface 113 abut against each other, preventing the first clamping part 110 from exiting from the first clamping interface 310.

[0054] Further, the first clamping part 111 has a connecting end and a free end, the connecting end is connected with the connecting end of another first clamping part, and the free end is outwardly bent to form a first abutting surface 114;

[0055] One end of the second clamping part 210 is connected with one end of another second clamping part 210, and each second clamping part 210 is outwardly bent away from one end of another second clamping part 210 to form a second abutting surface 220, and the first abutting surface 114 abuts against the second abutting surface 220.

[0056] Further, the body 116 has an extension section, the second clamping interface 112 is formed between the extension section and the second clamping part 210, one end of the second clamping part 210 away from the body 116 is outwardly bent to form a first abutting surface 114, and one end of the extension section away from the body 116 forms the first abutting surface 114;

[0057] One end of the second clamping part 210 is connected with one end of another second clamping part 210, and each second clamping part 210 is outwardly bent away from one end of another second clamping part 210 to form a second abutting surface 220, and the first abutting surface 114 abuts against the second abutting surface 220.

[0058] The first abutting surface 114 and the second abutting surface 220 abut, which can prevent the second clamping piece 200 from continuing to extend into the second clamping port 112 after being clamped into the first clamping piece 110; meanwhile, when the first clamping piece 110 is clamped into the first clamping port 310, the first clamping part 111 can extrude the second clamping part 210 inward, so that the second clamping piece 200 cannot exit the first clamping port 310, and the clamping strength of the first clamping piece 110 and the second clamping piece 200 is enhanced.

[0059] Further, the first clamping piece 110 is made of plastic material, and the second clamping piece 200 is made of metal material.

[0060] The second clamping piece 200 is a metal NUT, which can continuously provide the first clamping part 111 with a force after the plastic of the first clamping piece 110 fails, so as to prevent the first clamping piece 110 from exiting the first clamping port 310 and causing the decorative piece 100 to shake, make abnormal sound or even fall off.
