Wheel hub cover assembly to prevent mis-installation

Abstract

The present invention proposes a wheel hub decorative cover assembly, which can effectively prevent the wrong installation of the steel rim by setting two limit bends that are not in the same straight line and then correspondingly setting limit posts. Because the positions of the limit posts are different for cover bodies of different models, if the wrong steel rim is used, the two limit posts cannot be tightly embedded in the limit bends during the assembly process; the scheme of setting two limit bends in opposite directions can prevent the steel rim from being installed upside down; similarly, the inclined valve avoidance bend can also quickly check when the steel rim is installed upside down; the limit post and the first buckle are fixed to each other, and the force applied by the steel rim to the limit post can be transmitted to the first buckle, so that the steel rim is close to the first buckle, thereby improving the degree of firmness of the clamping between the first buckle and the wheel hub.

Description

Technical Field

[0001] The invention relates to the field of wheel hub decorative covers, and in particular to a wheel hub decorative cover assembly capable of preventing mis-installation. Background Art

[0002] The wheel hub decorative cover is mainly used for external decoration of the wheel hub. The existing wheel hub decorative cover assembly generally includes a wheel hub decorative cover and a steel rim. The wheel hub decorative cover includes a cover body, and a first buckle, a support seat and a second buckle integrally formed therewith, wherein the first buckle is used to clamp the wheel hub externally to fix the entire wheel hub decorative cover assembly on the wheel hub; the support seat provides axial support to the steel rim; the second buckle provides axial compression to the steel rim in the opposite direction to the support seat to prevent it from falling off; the steel rim provides radial supporting force to multiple first buckles, so that they are firmly clamped on the wheel hub. At the same time, the steel rim can also play a shaping role for the plastic wheel hub decorative cover.

[0003] At present, wheel hub cover manufacturers often need to produce wheel hub covers for multiple car companies and multiple models at the same time. The inner ring sizes of wheels from different car companies are often not much different, and the corresponding steel ring diameters are also not much different. It was found during production that steel rings with small diameter differences can often be assembled into non-corresponding wheel hub covers, and after the above assembly errors occur, it is difficult to detect visually. In this way, after the incorrectly installed wheel hub cover assembly is snapped onto the wheel hub, if the steel ring diameter is small, it will not be able to provide sufficient radial support force to the first buckle, resulting in the first buckle and the wheel hub not being firmly snapped together, and the pull-out force is insufficient. The wheel cover is easily caused to fall off during driving, leading to quality and safety accidents. Summary of the invention

[0004] In view of this, the present invention provides a wheel hub decorative cover assembly that prevents mis-assembly.

[0005] The technical solution of the present invention is implemented as follows: The present invention provides a wheel hub decorative cover assembly, which includes a wheel hub decorative cover and a steel ring, the wheel hub decorative cover includes a cover body, and a plurality of first buckles, a plurality of support seats and a plurality of second buckles integrally formed therewith, wherein the plurality of first buckles are arranged along the circumferential direction and clamp the wheel hub externally; the plurality of support seats are arranged along the circumferential direction and provide axial support to the steel ring; the plurality of second buckles provide axial compression to the steel ring opposite to the support seats; the steel ring and the plurality of first buckles resist each other and provide radial supporting force thereto, the steel ring includes a circular steel ring body, at least two limit bends are arranged on the steel ring body, at least two limit columns integrally formed therewith are arranged on the cover body, the two limit bends and the line connecting the center points of the steel ring form an angle greater than 0° and less than 180°, the circular steel ring body is embedded between the support seat and the second buckle, and the limit column is embedded inside the limit bend.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, combined Figure 2 to Figure 7 The hub decorative cover assembly of the present invention comprises a hub decorative cover 1 and a steel rim 2.

[0027] The hub cover 1 , which may also be called a hub cover or a wheel cover, is generally made of plastic and comprises a cover body 11 , a first buckle 12 , a support seat 13 , a second buckle 14 and a limiting column 15 .

[0028] Among them, as part of the prior art, the plurality of first buckles 12 , the plurality of support seats 13 and the plurality of second buckles 14 are all integrally formed with the cover body 11 .

[0029] Among them, a plurality of first buckles 12 are arranged along the circumferential direction and clamp the wheel hub outwardly. Generally speaking, the number of the first buckles 12 is determined according to the support frame (i.e., the connecting entity between the plurality of hollow holes, generally arranged corresponding to the wheel hub shaft) arranged inside the cover body 11, and each support frame is correspondingly provided with a first buckle 12. The first buckle 12 is buckled outwardly and clamped on the wheel hub.

[0030] A plurality of support seats 13 are arranged along the circumferential direction and provide axial support for the steel ring 2. Specifically, the number of the support seats 13 can be determined according to the first buckle 12, and the support seats 13 are arranged on one side or both sides of each first buckle 12. In this embodiment, the support seats 13 are directly connected to the cover body 11, and the two ends of the first buckle 12 are respectively connected to the two support seats 13.

[0031] The plurality of second buckles 14 provide axial compression to the steel ring 2 in the opposite direction to the support seat 13. Specifically, the number of the second buckles 14 can be determined according to the first buckles 12, and one or more second buckles 14 are correspondingly arranged on each first buckle 12. In this embodiment, the second buckle 14 is arranged in the middle of the first buckle 12.

[0032] The steel ring 2 is generally made of a metal material with good rigidity. It abuts against the multiple first buckles 12 and provides radial support to them, so that the outward-facing snapping interface of the first buckles 12 can be firmly snapped with the wheel hub. The steel ring 2 includes a circular steel ring body 21, a limit bend 22, and a valve avoidance bend 23.

[0033] The circular steel ring body 21 adopts a circular ring structure, is embedded between the support seat 13 and the second buckle 14, and is tightly connected with the back sides of the plurality of first buckles 12.

[0034] As a key improvement part of the present invention, at least two limit bends 22 are provided on the steel ring body 21, and at least two limit columns 15 integrally formed therewith are provided on the cover body 11, and the limit columns 15 of the circular steel ring body 21 are embedded in the limit bends 22. In this way, the distance between the two limit bends 22 of steel rings of different sizes is different, and they cannot be stuck on the two limit columns 15 of non-corresponding models, thereby preventing the wrong model from being installed. The reason why at least two limit bends 22 are provided is that more than two points can play a role in limiting. Specifically, the angle between the two limit bends 22 and the line connecting the center points of the steel ring 2 is greater than 0° and less than 180°, because if the two limit bends 22 are in a straight line, they will not play a role in preventing wrong installation.

[0035] With regard to the setting position of the limiting column 15, preferably, the limiting column 15 is fixed to the first buckle 12. In this way, the force applied by the steel ring 2 on the limiting column 15 can be transmitted to the first buckle 12, so that the steel ring 2 is close to the first buckle 12, and the degree of firmness of the clamping between the first buckle 12 and the wheel hub is improved.

[0036] Regarding the setting direction of the limit bend 22, as an implementation method, Figure 6 As shown, there are two limit bends 22, and the bending directions are the same, both of which are toward the inside of the steel ring 2. In this way, the force direction of the steel ring 2 is consistent with the limit column 15 and the first buckle 12, but there is also the problem that the steel ring 2 is installed upside down.

[0037] Regarding the setting direction of the limit bend 22, as another implementation, Figure 7 As shown, there are two limit bends 22, and the bending directions are opposite, respectively toward the inside and outside of the steel ring 2. In this way, the force directions of the limit column 15 and the first buckle 12 on the steel ring 2 are inconsistent, which easily causes the limit column 15 and the first buckle 12 to bend under force, but can effectively prevent the problem of the steel ring 2 being installed upside down.

[0038] Regarding the shape design of the limiting bend 22 , as an implementation mode, the limiting bend 22 adopts an arc design, and the radius of the steel ring body 21 is 10 to 20 times the radius of the limiting bend 22 .

[0039] Regarding the shape design of the limit bend 22, as another implementation, the cross section of the limit column 15 is an isosceles triangle, and the top and bottom corners are chamfered. The cross section of the limit bend 22 is an isosceles triangle, and the top and bottom corners are chamfered.

[0040] As another solution to prevent the steel ring 2 from being installed upside down, specifically, a valve avoidance bend 23 is provided on the steel ring body 21, and a valve avoidance groove 10 is provided on the cover body 11. The valve avoidance groove 10 is for the automobile tire valve to pass through, and the valve avoidance bend 23 is inclined toward one side of the valve avoidance groove 10 and abuts against the outer wall of the valve avoidance groove 10. Specifically, there are two limit bends 22, and the valve avoidance bend 23 is located between the two limit bends 22. In this way, when the steel ring 2 is installed upside down, the inclined valve avoidance bend 23 is obviously tilted upward, which is convenient for the assembler to check and correct. Specifically, the outer wall of the valve avoidance groove 10 is provided with an inclined slope 100, and the middle of the valve avoidance bend 23 is a straight section, and the straight section in the middle of the valve avoidance bend 23 and the inclined slope 100 abut against each other.

[0041] The hub cover assembly of the present invention can ensure that the two limit posts 15 are exactly inserted into the two limit bends 22 during assembly only if the hub cover 1 and the steel ring 2 are of the same model, thereby effectively preventing wrong assembly. The practical test shows that the effect is good, the production cost will not be greatly increased, and it is worthy of large-scale promotion and application.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
