Generally speaking, it is the part of the wheel center where the axle is installed, and it is an important component connecting the brake drum (brake disc), wheel disc and half shaft. In general vehicles, the inner side of the hub is connected to the wheel axle, and a hub cap is sleeved outside, making the whole look more beautiful. Generally, the center of the hub is provided with an installation hole for installing the hub cap, and the aperture sizes of the installation holes of different models of hubs are different.

[0003] Traditional hub caps have the following deficiencies: First, most of the existing hub caps are designed for a specific size of hub. A number of plastic material buckles adapted to the corresponding installation aperture diameters are formed on the inner ring, so as to ensure that the hub cap can be conveniently snapped into the center installation hole of the hub from the outside of the hub, and ensure that the outer ring of the hub cap fits the outer ring of the center installation hole of the hub.

Detailed implementation manners

[0045] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0046] Referring to Figures 1 to 13 A hub cap applicable to multiple vehicle models shown in the figure, the rim 1 and the hub cap 2 are connected by a universal connector, and the universal connector includes:

[0047] A fixed inner disc 3 in a disc - shaped structure, on one side of which close to the inner side of the rim 1, a plurality of elastic snaps are slidably connected along its radial direction and are equally - angularly distributed for clamping the inner side of the rim 1 from inside to outside, and on the other side of the fixed inner disc 3, a connecting column sleeve 4 for the hub cap 2 to be snap - connected is also formed;

[0048] A driven disc 5, coaxially and pivotally connected to the fixed inner disc 3 and used for driving a plurality of elastic snaps to translate along the radial direction of the fixed inner disc 3, and an axial convex shaft 6 for sliding cooperation with each other and a plurality of arc - shaped through - slots corresponding to the plurality of axial convex shafts 6 are respectively formed at one end of the elastic snap close to the axis of the fixed inner disc 3 and on the driven disc 5;

[0049] An outer column sleeve 7, one end of which far from the fixed inner disc 3 is open and coaxially and fixedly connected to one side of the fixed inner disc 3 close to the outer side of the rim 1;

[0050] An inner column sleeve 8, axially limited and coaxially and pivotally connected inside the outer column sleeve 7;

[0051] A planetary reduction mechanism is provided on the fixed inner disk 3 and is used for drivingly connecting the inner column sleeve 8 and the driven disk 5;

[0052] An adjustable-diameter pressing ring 9 is axially and coaxially slidably arranged on the outer column sleeve 7 and is elastically connected to the outer column sleeve 7. An irregular ring groove 10 is formed on the outer cylindrical wall of the inner column sleeve 8, and a driving sliding shaft 11 slidably arranged in the irregular ring groove 10 is fixedly connected to the adjustable-diameter pressing ring 9. After the adjustable-diameter pressing ring 9 is axially translated along the outer column sleeve 7 to a specific position, it can drive the inner column sleeve 8 to rotate by a corresponding angle and lock through the cooperation of the driving sliding shaft 11 and the irregular ring groove 10;

[0053] A closing snap ring 12 is coaxially clamped and sleeved outside the connecting column sleeve 4 and tightly clamps the rim 1 from outside to inside. The outer ring of the closing snap ring 12 fits with the rim 1;

[0054] Among them, the driven disk 5, the outer column sleeve 7, the inner column sleeve 8, the planetary reduction mechanism, and the adjustable-diameter pressing ring 9 are all located inside the connecting column sleeve 4.

[0055] A first convex shaft 13 for axially connecting with the fixed inner disk 3 is formed at the center of one end of the driven disk 5 close to the fixed inner disk 3, and the inner column sleeve 8 is axially connected to the first convex shaft 13. Four second convex shafts 14 are also formed on the driven disk 5 and are equally angularly distributed along its axis and are connected to the planetary reduction mechanism. Four avoidance through grooves 15 corresponding to the four second convex shafts 14 one by one and for allowing the driven disk 5 to rotate by a certain angle are formed on the fixed inner disk 3. The driven disk 5 can be axially connected to the fixed inner disk 3 through the first convex shaft 13. After the inner column sleeve 8 is axially connected to the first convex shaft 13 and then the first convex shaft 13 and the inner column sleeve 8 are axially limited, the driven disk 5 and the inner column sleeve 8 can be axially connected to the fixed inner disk 3 while being axially limited. Referring to Figure 6 、 Figure 9 and Figure 10 As can be easily seen from the structures of the driven disk 5, the driving sliding shaft 11, and the arc-shaped through groove shown, when the driven disk 5 rotates by a very small angle, the driving sliding shaft 11 can be driven to axially translate a long distance along the radial direction of the fixed inner disk 3 through the arc-shaped through groove. In this way, the distance between the ends of several elastic buckles and the fixed inner disk 3 can be changed, so that the universal connecting piece can be clamped on the rim 1 with a central mounting hole of different sizes.

[0056] The planetary reduction mechanism includes:

[0057] A fixed gear ring 16 with teeth formed on its inner ring is coaxially and fixedly connected to one end of the fixed inner disk 3 far from the driven disk 5 and is fixedly connected to the outer column sleeve 7;

[0058] Four planetary gears 17 are fixedly connected to four second convex shafts 14 one by one, and the four planetary gears 17 are all meshed with the inner ring of the fixed gear ring 16. An outer gear ring 18 for meshing with the four planetary gears 17 is formed at one end of the inner bush 8 close to the fixed inner disc 3.

[0059] Since the driven disc 5 rotates following the rotation of the inner bush 8, and the driven disc 5 can change a large radial displacement amount of the elastic buckle by rotating a small angle. Refer to Figure 6 and Figure 7 As shown, the inner bush 8 provided with the outer gear ring 18 is used as the driving member and is set as the central sun gear, which cooperates with the fixed gear ring 16 to drive the four planetary gears 17 to rotate, so as to drive the driven disc 5 to rotate through the four second convex shafts 14, and after the inner bush 8 rotates a certain angle, the driven disc 5 rotates a smaller angle.

[0060] One end of the inner bush 8 close to the fixed inner disc 3 is axially connected to the first convex shaft 13. The other end of the inner bush 8 is open, and an outer circular plate 19 axially connected to the first convex shaft 13 is coaxially fixedly connected to this end. The inner bush 8 can be either a solid cylindrical structure or a similar hollow cylindrical structure. Considering cost savings, the inner bush 8 is set as Figure 11 and Figure 12 As shown in the structure, through the cooperation of the inner bush 8 and the outer circular plate 19, it can ensure the stable movement of the driven disc 5 and the inner bush 8 while saving materials.

[0061] The diameter-adjusting pressure ring 9 is of an annular structure. Two symmetrically arranged pressing plates 20 and several limiting convex blocks 21 distributed at equal angles along its axis are formed on the outer cylindrical wall of the diameter-adjusting pressure ring 9. Two strip-shaped through grooves 22 for avoiding the pressing plates 20 are formed on the side wall of the outer bush 7, and the outer ends of the pressing plates 20 protrude from the outer cylindrical wall of the outer bush 7. Several limiting through grooves 23 corresponding to the several limiting convex blocks 21 are also formed on the inner wall of the outer bush 7. A cylindrical through groove and a side wall convex block 24 for fixedly connecting with the transmission sliding shaft 11 are also formed on the outer cylindrical wall of the diameter-adjusting pressure ring 9. A circular ring portion 25 for fixedly connecting with the side wall convex block 24 is formed at one end of the transmission sliding shaft 11 away from the inner bush 8, and the other end of the transmission sliding shaft 11 is slidably arranged in the special-shaped ring groove 10. Refer to Figure 12 The structure of the diameter-adjusting pressure ring 9 shown in Figure 8 The corresponding end structure of the outer bush 7 shown in Figure 13For the structure of the special-shaped ring groove 10 shown, the diameter-adjusting pressing ring 9 is axially translatably arranged on the outer cylindrical sleeve 7 under the action of a plurality of limiting bumps 21 and limiting through grooves 23. Also, since the diameter-adjusting pressing ring 9 is fixedly connected with a transmission sliding shaft 11 that is slidably arranged in the special-shaped ring groove 10, when the diameter-adjusting pressing ring 9 moves axially, because the diameter-adjusting pressing ring 9 cannot rotate and the transmission sliding shaft 11 slides in the special-shaped sliding groove, due to the special structure of the special-shaped ring groove 10, it can be realized that when the moving transmission sliding shaft 11 slides in the special-shaped ring groove 10, the inner cylindrical sleeve 8 rotates accordingly.

[0062] Two symmetrically arranged elastic tape measures 26 for resetting the diameter-adjusting pressing ring 9 are fixedly connected to the inner cylindrical wall of the outer cylindrical sleeve 7. The outer ends of the elastic tape measures 26 are fixedly connected to the outer cylindrical sleeve 7, and the inner ends of the elastic tape measures 26 extend along the inner wall of the outer cylindrical sleeve 7 towards the fixed inner disc 3 and the ends are formed into a coil spring structure. Two limiting convex plates 27 for pressing the inner ends of the two elastic tape measures 26 are also formed on the outer cylindrical wall of the diameter-adjusting pressing ring 9. Refer to Figure 12 For the structure of the elastic tape measure 26 shown, when the diameter-adjusting pressing ring 9 moves towards the fixed inner disc 3 in the outer cylindrical sleeve 7, the coil spring structure of the elastic tape measure 26 will bring a force to the diameter-adjusting pressing ring 9 to move away from the fixed inner disc 3. Refer to Figure 13The front view of the inner bushing 8 shown. When looking directly at the special-shaped annular groove 10, the corresponding positions of points b, c, and e should be respectively on the left side of the corresponding positions of points a, d, and f. When the diameter-adjusting pressing ring 9 is at the position farthest from the fixed inner disk 3, that is, when the transmission sliding shaft 11 is at the uppermost right position of the special-shaped annular groove 10. At this time, due to the force of the elastic tape measure 26 on the diameter-adjusting pressing ring 9 and the limitation of the special-shaped annular groove 10 on the transmission sliding shaft 11, the diameter-adjusting pressing ring 9 will not move further without a certain magnitude of pressure towards the fixed inner disk 3. When manually moving the diameter-adjusting pressing ring 9 towards the fixed inner disk 3, the transmission sliding shaft 11 will finally slide along the right chute of the special-shaped chute to point b. Similarly, at this time, due to the limitation of the special-shaped chute on the transmission sliding shaft 11, the diameter-adjusting pressing ring 9 will be stuck and unable to move further. After removing the force on the diameter-adjusting pressing ring 9, since point b is on the left side of point a and the diameter-adjusting pressing ring 9 moves back under the elastic force of the elastic tape measure 26, the transmission sliding shaft 11 will slide along the special-shaped chute to point c and be stuck again. In this way, after manually applying a continuous pressure to the diameter-adjusting pressing ring 9 towards the fixed inner disk 3 until the diameter-adjusting pressing ring 9 is stuck, after removing the force, the diameter-adjusting pressing ring 9 moves back and is stuck again, and the transmission sliding shaft 11 moves from point g to point c, and the inner bushing 8 rotates by a corresponding angle. Since the diameter-adjusting pressing ring 9 cannot rotate, the angle of rotation of the inner bushing 8 exactly corresponds to the angle between the axial center plane where point g is located and the axial center plane where point c is located on it. Similarly, when manually applying pressure to the diameter-adjusting pressing ring 9 subsequently, the transmission sliding shaft 11 can move from point c to point e again, and then move back from point e to point g. When the transmission sliding shaft 11 moves back from point e to point g, the inner bushing 8 rotates back to the initial state in the corresponding direction. By reasonably setting the cooperation between various parts, the transmission sliding shaft 11 can move from point g to point c and from point c to point e, and several elastic buckles move twice along the radial direction of the fixed inner disk 3 away from the axis of the fixed inner disk 3, while when the transmission sliding shaft 11 moves back from point e to point g, several elastic buckles move along the radial direction of the fixed inner disk 3 towards the axis of the fixed inner disk 3 and return to their original positions. In this way, the distance between the outer ends of several elastic buckles and the axis of the fixed inner disk 3 can be changed, and it can be clamped on different specifications of the wheel rim 1.

[0063] One end of the outer bushing 7 away from the fixed inner disk 3 is coaxially and fixedly connected with a fixed outer disk 28. Two pressing convex blocks 29 for pressing against the outer ends of the two elastic tape measures 26 are formed at one end of the fixed outer disk 28 close to the fixed inner disk 3. The fixed outer disk 28 can play a role in strengthening the outer bushing 7, and the pressing convex blocks 29 can prevent the elastic tape measure 26 from loosening on the outer bushing 7 accidentally, thus affecting the diameter-adjusting pressing ring 9.

[0064] On the corresponding side of the fixed inner disc 3, a plurality of radial chutes are provided, which correspond one-to-one to a plurality of elastic buckles and are equally angularly distributed along its axis. The elastic buckle includes a buckle plate 30 that clamps the rim 1 and a sliding rod 31 that is slidably disposed in the corresponding radial chute. One end of the buckle plate 30 and the sliding rod 31 away from the axis of the fixed inner disc 3 are fixedly connected, and the axial convex column is fixedly connected to one end of the corresponding sliding rod 31 close to the axis of the fixed inner disc 3. Through the limitation of the sliding rod 31 by the radial chute, in cooperation with the arc-shaped through groove and the axial convex column, after the driven disc 5 rotates a certain angle, the buckle plate 30 can cooperate with the sliding rod 31 to translate along the radial chute.

[0065] Inner clamping rings 32 and outer clamping rings 33 for clamping the hub cap 2 and the closing snap ring 12 are respectively formed on the inner cylindrical wall and the outer cylindrical wall of the connecting column sleeve 4. A plurality of first buckles 34 for clamping and cooperating with the inner clamping ring 32 are formed at one end of the hub cap 2 close to the fixed inner disc 3, and a plurality of second buckles 35 for clamping and cooperating with the outer clamping ring 33 are formed at one end of the closing snap ring 12 close to the fixed inner disc 3. The closing snap ring 12 needs to be manufactured according to the sizes of the connecting column sleeve 4 and the corresponding rim 1, and is only applicable to the rim 1 with the aperture of the central mounting hole larger than the maximum outer diameter of the fixed inner disc 3, ensuring that when the aperture of the central mounting hole of the target rim 1 is relatively large, the closing snap ring 12 can block the gap between the outer circle of the fixed inner disc 3 and the central mounting hole of the rim 1, thereby ensuring aesthetics.

[0066] Refer to Figures 1 to 13 A usage method of a hub cap applicable to multiple vehicle models as shown, the usage method includes the following steps:

[0067] S1. According to the aperture size of the central mounting hole of the corresponding rim 1, by adjusting the axial position of the diameter-adjusting pressure ring 9 in the outer column sleeve 7, the inner column sleeve 8 is rotated by a corresponding angle, and then through the transmission of the planetary reduction mechanism, the driven disc 5 is rotated by a corresponding angle, so that through the cooperation of a plurality of arc-shaped through grooves and the axial convex shaft 6, a plurality of elastic buckles are radially adjusted to the corresponding positions along the fixed inner disc 3 to adapt to the aperture of the central mounting hole of the rim 1;

[0068] S2. Connect the hub cap 2 and the closing snap ring 12 adapted to the size of the rim 1 to the connecting column sleeve 4;

[0069] S3. Through a plurality of elastic buckles, the universal connecting piece together with the hub cap 2 is clamped into the central mounting hole of the rim 1.

[0070] Working principle: All parts in the present invention are made of plastic, and the fixed connections between various parts are achieved by ultrasonic welding or bonding with strong glue. During installation, first, a number of elastic buckles are slidably arranged on the fixed inner disc 3. After sleeving the diameter-adjusting pressing ring 9 on the inner column sleeve 8, the driving sliding shaft 11 and the diameter-adjusting pressing ring 9 are fixedly connected. Then, the driven disc 5 is axially connected to the fixed inner disc 3 and several axial convex shafts 6 are arranged in the corresponding arc-shaped through grooves. Subsequently, four planetary gears 17 can be sleeved on the four second convex shafts 14 but not fixed. Wait until the positions of the fixed gear ring 16 and the inner column sleeve 8 are adjusted later, so that after the fixed gear ring 16, the four planetary gears 17 and the outer gear ring 18 are meshed, then the four second convex shafts 14 and the four planetary gears 17 are fixedly connected. After fixing the two elastic measuring tapes 26 on the outer column sleeve 7, then install the outer column sleeve 7 and the inner column sleeve 8. Connect the inner column sleeve 8 to the first convex shaft 13 and match the diameter-adjusting pressing disc with the outer column sleeve 7, and make the limit convex plate 27 press the elastic measuring tape 26. Finally, mesh the outer gear ring 18 with the four planetary gears 17 and axially limit the inner column sleeve 8. Finally, install the fixed outer disc 28. This hub cap applicable to multiple vehicle models (hereinafter referred to as multi-purpose hub cap), when all the elastic buckles are retracted along the radial sliding grooves to the position closest to the axis of the fixed inner disc 3, several elastic buckles can be snapped into the corresponding central mounting holes of the corresponding size. At this time, the wheel rim 1 with the central mounting hole diameter of this size that the multi-purpose hub cap can adapt to is the wheel rim 1 with the smallest size central mounting hole that the multi-purpose hub cap can be applicable to. Refer to Figure 13 As shown in the front view of the inner column sleeve 8, the section from point g to point c is the first falling and rising section, and the section from point c to point e is the second falling and rising section. Corresponding to this, several elastic buckles can increase the distance from their outermost ends to the axis of the fixed inner disc 3 twice, that is, corresponding to two wheel hubs with larger size central mounting holes that the multi-purpose hub cap can be applicable to. Similarly, according to the size of the central mounting hole of the corresponding wheel hub and the size of the connecting column sleeve 4, design the size of the corresponding closing snap ring 12 to ensure that the outer ring of each closing snap ring 12 can fit the corresponding wheel hub. Also, according to the needs, design the number of several falling and rising sections and the angles between them in the special-shaped ring groove 10, so that the multi-purpose hub cap can adapt to wheel hubs with more size central mounting holes; during use, according to the size of the central mounting hole of the target wheel hub, first assemble the multi-purpose hub cap (the hub cap 2 is not assembled first), then manually adjust the distance between the diameter-adjusting pressing ring 9 and the fixed inner disc 3 accordingly, so that the driving sliding shaft 11 is located at the corresponding position of the special-shaped ring groove 10, thereby ensuring that several elastic buckles can just be snapped into the central mounting hole of the wheel hub. Finally, install the hub cap 2.
