Technical Field

[0001] The invention relates to the field of wheels, in particular to a low wind resistance wheel assembly and a vehicle having the low wind resistance wheel assembly. Background Art

[0002] When a vehicle is moving, it is subject to resistance from the outside air, among which the aerodynamic resistance of the wheel cavity is an important component of the entire air resistance.

[0003] The wheels mainly rotate during driving, forming a relatively complex airflow around the wheels, which ultimately affects the wind resistance of the entire vehicle.

[0004] In the prior art, if a wheel is installed with a decorative cover, the decorative cover is mostly a closed structure and the decorative cover is fixed, and the spoke gap is always closed. This can reduce the airflow through the spokes, so that the airflow in the front of the vehicle can flow more to the rear of the vehicle, reducing the airflow inside the wheel cavity, and achieving the effect of reducing the aerodynamic resistance of the wheel cavity.

[0005] Although the closed decorative cover helps to reduce wind resistance, it cannot take into account the heat dissipation requirements of the brake disc during braking; at the same time, the overall structure of the decorative cover is complex and the production cost is high.

[0038] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0039] A low wind resistance wheel assembly comprises a wheel 1, wherein the wheel 1 comprises a wheel body 11, and a window 12 is provided on the wheel body 11; an opening adjustment mechanism 2 is provided in the window 12; the low wind resistance wheel assembly disclosed in the present invention can control the opening of the window 12 as needed through the setting of the opening adjustment mechanism 2, thereby changing the running resistance of the wheel 1 as needed.

[0040] In addition, the present invention takes into account both the need to reduce wind resistance when the vehicle is traveling and the need to dissipate heat from the brake disc when the vehicle is braking, by providing the opening adjustment mechanism 2 .

[0041] The arrangement of the opening adjustment mechanism 2 in the present invention can choose to close the spoke gap when the vehicle is traveling, and can also expose the spoke gap when the vehicle is braking, so as to meet different usage requirements according to different working conditions.

[0042] The low wind resistance wheel assembly disclosed in the present invention mainly includes a wheel 1, which includes a wheel body 11, and a window 12 is provided on the wheel body 11; the wheel 1 is the main structure of the wheel assembly, and generally a similar traditional structural design can be selected. Of course, in order to cooperate with the installation of the opening adjustment mechanism 2, local improvements can be made during actual production.

[0043] In the present invention, the wheel body 11 mainly includes a spoke 14 , a rim 13 and a window 12 ; these three components are also structures that all conventional wheels 1 have.

[0044] In the present invention, an opening adjustment mechanism 2 is arranged in the window 12 area of ​​the wheel body 11; the opening adjustment mechanism 2 is arranged in the window 12 for controlling the opening of the window 12 during actual use.

[0045] Specifically, in the present invention, the opening adjustment mechanism 2 includes a cover plate 21; the cover plate 21 is arranged on the window 12 area to control the opening of the window 12; the cover plate 21 covers the side of the wheel body 11 corresponding to the window 12 close to the side of the vehicle body.

[0046] In addition, in the present invention, a plurality of windows 12 are provided on the wheel body 11 , and theoretically, an opening adjustment mechanism 2 is arranged in each window 12 .

[0047] In addition, the cover plate 21 in the present invention includes a plurality of single plate bodies 211, and the plurality of single plate bodies are stacked in sequence; the cover plate 21 in the present invention is designed similar to a fan, which facilitates the subsequent opening and retracting of the cover plate 21 and is convenient for practical use.

[0048] In the present invention, one ends of the plurality of single panels are connected by a connecting component; the provision of the connecting component facilitates the connection between the single panels, and the principle is similar to the connection method at the bottom of a fan; similarly, in order to facilitate the subsequent opening of the cover 21, in the present invention, the adjacent single panels can rotate relative to each other around the connecting component; such a provision facilitates the retraction and extension control of the cover 21.

[0049] Furthermore, in the present invention, the connecting component includes a connecting pin 23 and a through-hole 24 arranged on each single plate; the connecting pin 23 is connected to the wheel body 11 through the through-hole 24 on each single plate in turn; the connecting pin 23 in the present invention not only acts as a connecting shaft, but also acts as a rotating shaft. In the present invention, the connecting pin 23 passes through the through-hole 24 on multiple single plates 211 in turn, which facilitates the connection between multiple single plates.

[0050] In the present invention, the connecting pin 23 can also serve as a rotating shaft, so that when it is used later, the single plate body 211 can be rotated on the connecting pin 23; in addition, in the present invention, the through hole 24 on the single plate and the connecting pin 23 can be connected by interference fit. For example, a rubber layer can be provided on the inner wall of the through hole 24. Such a setting can not only ensure the stable connection of the single plate to the connecting pin 23, but also facilitate the subsequent rotation operation of the single plate on the connecting pin 23.

[0051] In addition, in the present invention, the connecting pin 23 can be fixedly connected to the wheel body 11, or can be designed to be rotatably connected as needed, and the specific selection can be made according to needs.

[0052] Furthermore, in the present invention, the connecting component also includes a support block 3 arranged at one end of the window 12 away from the rim 13 of the wheel 1; the connecting pin 23 is connected to the support block 3; in the present invention, the support block 3 has two functions. The support blocks 3 are distributed at the corners of the window 12, mainly arranged at the connection between adjacent spokes 14, and play a good reinforcement role to ensure the structural strength of the connection between adjacent spokes 14. At the same time, the support block 3 is equivalent to providing a connection place for the connecting component, which facilitates the installation and fixation of the cover plate 21 on the wheel body 11.

[0053] Furthermore, in the present invention, two adjacent single plate bodies 211 are connected via a linkage mechanism. The setting of the linkage mechanism can ensure the linkage of the movements between the single plate bodies 211. During subsequent use, the linkage mechanism can not only realize the movement guidance between the adjacent single plate bodies 211, but also facilitate the movement linkage between the single plate bodies 211 by limiting the opening method of the hanging groove 212.

[0054] In the present invention, the linkage mechanism includes a hanging protrusion arranged on one of the single plate bodies 211 and a hanging groove 212 arranged on the other single plate body 211; the hanging protrusion in each linkage mechanism is connected to the corresponding hanging groove 212; such a setting makes the linkage mechanism and the connecting pin shaft act as two connection points, which better ensures the stability of the movement of adjacent single plate bodies 211 and the stability of the connection.

[0055] Meanwhile, in the present invention, the hanging groove 212 is an arc groove; the center of the arc groove is arranged concentrically with the center of the connecting pin shaft 23. Such an arrangement can avoid the setting of the linkage mechanism affecting the relative movement between adjacent single plates 211.

[0056] In addition, in the present invention, only one side of the hanging groove 212 is connected to the side of the single plate body 211. This arrangement allows the side wall of the hanging groove 212 to form a limiting protrusion, thereby cooperating with the hanging protrusion to achieve operational linkage between the single plate bodies 211.

[0057] In the present invention, the cover plate 21 is connected to the wheel body 11 via a fastening mechanism, and the fastening component is mainly used for fastening and installing the cover plate 21 on the wheel body 11 .

[0058] In addition, the fastening mechanism in the present invention includes a supporting guide rib 4 arranged on the side of the window 12 close to the rim of the wheel 1 and an upper pin body 22 arranged on the cover plate 21; the supporting guide rib 4 is provided with a fastening socket 41; in the present invention, the supporting guide rib 4 acts as a reinforcing rib, which can well ensure the structural strength of the area of ​​the window 12 close to the rim 13; in addition, the supporting guide rib 4 also plays a good supporting and raising role, avoiding deformation of the single plate body 211 away from the end of the connecting pin shaft 23.

[0059] In addition, in the present invention, the cover plate 21 is connected to the fastening socket 41 on the supporting guide rib 4 through the upper pin body 22; the upper pin body 22 acts as a plug-in column, and when used later, it is plugged into the fastening socket 41 corresponding to the supporting guide rib 4, thereby realizing the locking and fixation of the cover plate 21 away from one end of the connecting pin shaft 23.

[0060] Furthermore, in the present invention, a plurality of fastening holes 41 are provided on the supporting guide rib 4; adjacent fastening holes 41 are distributed at intervals; an upper pin body 22 is provided on at least one single plate body 211 in the cover plate 21; through such an arrangement, the present invention facilitates ensuring the stability of the connection of the cover plate 21 on the supporting guide rib 4, and through the arrangement of a plurality of fastening holes 41, the locking and fixation of the cover plate 21 at different opening degrees can be achieved.

[0061] In addition, at least one of the single plates 211 in the cover plate 21 described in the present invention is provided with an upper pin body 22; it is generally required that the single plates 211 on both sides of the cover plate 21 have upper pin bodies 22, and in subsequent use, the positions of the single plates 211 on both sides of the cover plate 21 can be limited, and at the same time, in conjunction with the setting of the linkage mechanism, after the positions of the single plates 211 on both sides are limited, the positions of the single plates 211 in the middle can be limited, thereby ensuring the stability of the position of the cover plate 21 after it is unfolded.

[0062] In actual design, an upper pin body 22 can be set on each single plate body 211. At the same time, in order to avoid the setting, an arc-shaped groove body can be set on the corresponding single plate body 211 for avoidance; of course, such a setting may increase the design difficulty of the cover plate, so generally the upper pin body is set on a single plate body of the cover plate closest to the supporting guide rib 4.

[0063] At the same time, as a greater optimization, a fitting guide edge 2111 is provided on the innermost single plate body, and the fitting guide edge 2111 is arranged as a protrusion arranged on the corresponding single plate body; the fitting guide edge 2111 is arranged perpendicular to the corresponding single plate body, and the fitting guide edge 2111 is arranged on a single plate body closest to the inner side of the wheel in the cover plate; the fitting guide edge 2111 is an arc-shaped plate structure, and the fitting guide edge 2111 fits on the inner side of the supporting guide rib 4. In actual use, the fitting guide plate is on the inner wall of the supporting guide rib 4, and the single plate body is on the side of the supporting guide rib 4 close to the outside of the vehicle. This kind of cooperation method can further define the position of the cover plate to ensure its operation and stability of position during arrangement.

[0064] Furthermore, in the present invention, a storage groove 201 is provided on the inner wall of the window 12, and the storage groove 201 is arranged on the side of the spoke 14 in the wheel body 11; the setting of the storage groove 201 plays a good storage role, which is convenient for storing the cover plate 21 after retracting, avoiding or reducing the exposed size of the cover plate 21, and reducing the influence of the cover plate 21 on the heat dissipation of the wheel 1.

[0065] Furthermore, in the present invention, the end of the single plate body 211 close to the rim 13 of the wheel 1 is arc-shaped; such a configuration can avoid the operation interference between the single plate body 211 and the wheel body 11 when the single plate body 211 rotates; the center of the outer side surface of the single plate body 211 and the center of the connecting pin shaft 23 are at the same point.

[0066] In addition, in the present invention, the edge of the window 12 is connected to the side of the wheel body 11 by a guide slope 121; the setting of the guide slope 121 can reduce excessive wind resistance formed in the window 12 when the vehicle is running.

[0067] A vehicle comprises the low wind resistance wheel assembly.

[0068] specific:

[0069] The present invention discloses a low wind resistance wheel assembly; based on the existing wheel 1 structure, the present invention ingeniously optimizes the structure of the wheel 1 locally to propose a new low wind resistance and highly universal structural solution.

[0070] The low wind resistance wheel assembly disclosed in the present invention mainly comprises a rim 13 , a spoke 14 , a window 12 , and an opening adjustment mechanism 2 arranged in the window 12 .

[0071] The opening adjustment mechanism 2 disclosed in the present invention mainly comprises a cover plate 21 . The cover plate 21 is designed to have features similar to a fan. A support block 3 is provided at the lower end of the window 12 , and the support block 3 is connected to the cover plate 21 .

[0072] The cover plate 21 disclosed in the present invention mainly includes a plurality of single plate bodies 211. When used subsequently, the window 12 opening can be effectively adjustable by controlling the retraction and expansion of the plurality of single plate bodies 211. The wind resistance can be adjusted according to the needs of the whole vehicle. Corresponding patterns can be developed on the cover plate 21 to achieve diversified shapes, thereby saving product development costs and improving the appearance and economy of the whole vehicle.

[0073] In the present invention, the cover plate 21: the cover plate 21 is composed of a plurality of individual panels, which can be freely unfolded and closed. The overall shape of the cover plate 21 is designed to be fan-shaped or other polygonal. The structure can adjust the individual panels according to the use requirements to achieve different areas or sizes.

[0074] A through hole 24 is provided at the lower end of the cover plate 21 and is connected to a connecting axle pin. The connecting axle pin constrains the single plate so that the single plate can rotate concentrically along the axle pin of the through hole 24. An upper pin body 22 is provided at the upper end of the cover plate 21. The connection between the cover plate 21 and the wheel body 11 is subsequently achieved by inserting the upper pin body 22 into the corresponding fastening socket 41.

[0075] In actual use, the connection between the cover plate 21 and the wheel body 11 is achieved by inserting the upper pin body 22 on the cover plate 21 into the corresponding fastening socket 41; thereby, the cover plate 21 can be unfolded in a certain fixed shape.

[0076] Connecting axle pin: one end is connected to the cover plate 21, and the other end is connected to the lower through hole on the support block 3 on the wheel body 11. The size and shape of the connection between the connecting axle pin and the cover plate 21 are designed to match the through hole 24 on the cover plate 21, so that the cover plate 21 can be expanded or closed along the center axis of the connecting axle pin; the size and shape of the connection between the connecting axle pin and the wheel 1 are designed to match the hole on the support block 3, and can be designed to be circular or other polygonal, so that the cover plate 21 can fit tightly in the lower through hole, thereby ensuring that the lower end of the cover plate 21 is fixed to the support block 3 of the window 12 of the wheel 1.

[0077] Upper pin body 22: An interface of a certain size and shape is designed at the upper end of the single plate of the cover plate 21, which can be connected and fastened with one end of the upper pin body 22, so that the single plate of the cover plate 21 and the upper pin body 22 can rotate and move synchronously; a bayonet is provided at the other end of the upper pin body 22, and the size of the bayonet must be designed so that it can smoothly pass through the fastening socket 41 on the wheel 1 and fit tightly, so as to achieve the effect of fastening and locking the upper pin body 22 and the wheel 1, and at the same time fix the upper end of the cover plate 21.

[0078] The fastening mechanism, the cover plate 21 is connected to the wheel body 11 through the fastening mechanism, and the fastening mechanism includes a support guide rib 4 arranged on the side of the window 12 close to the rim of the wheel 1 and an upper pin body 22 arranged on the cover plate 21; the support guide rib 4 is provided with a fastening socket 41; the cover plate 21 is connected to the fastening socket 41 on the support guide rib 4 through the upper pin body 22: a row of fastening sockets 41 are designed at the intersection of the outer end of the bottom of the rim 13 of the wheel 1 and the upper end of the window 12 of the wheel 1, these fastening sockets 41 are all in a fixed size shape, and can be circular or other shapes suitable for matching with the bayonet, the outer end of the fastening socket 41 must be designed with a certain gradient opening, so that the bayonet in the upper pin body 22 can smoothly pass through and be fixed from the fastening socket 41, and the inner end of the fastening socket 41 must also be designed with a certain gradient opening, so that the bayonet in the upper pin body 22 can be smoothly taken out from the fastening socket 41.

[0079] Storage groove 201: In the middle part of the spokes of the wheel 1, grooves of a certain length and thickness are designed. These grooves are designed in a counterclockwise direction. The size and shape of these grooves are matched with the cover plate 21. When the cover plate 21 needs to be unfolded, the cover plate 21 can be rotated out of the groove. When the cover plate 21 needs to be stored, the individual panels in the cover plate 21 can be folded and stored in the storage groove 201.

[0080] The support block 3, the connecting pin 23 is connected to the support block 3; in the present invention, the support block 3 has two functions. The support block 3 is distributed at the corners of the window 12, and is mainly arranged at the connection between adjacent spokes 14, which plays a good reinforcement role and ensures the structural strength of the connection between adjacent spokes 14. At the same time, the support block 3 is equivalent to providing a connection place for the connecting component, which facilitates the installation and fixation of the cover plate 21 on the wheel body 11.

[0081] In addition, in the present invention, the support block and the support guide ribs play a role in limiting the end of the cover plate, thereby preventing the cover plate from warping when in use.

[0082] The support block 3 disclosed in the present invention is arranged at the lower end of the window 12 at the center disk of the wheel 1. In essence, an extended boss is designed at the lower end of the window 12 at the center disk of the wheel 1. A through hole is opened on the boss, which can be designed to be circular or other polygonal to ensure a close match with the connecting end of the connecting shaft pin.

[0083] In the present invention, the adjustment method and performance mechanism of the window 12 of the wheel 1 are as follows:

[0084] When adjusting the wheel 1 to reduce the window 12, first manually remove the upper pin body 22 on the cover plate 21 from the fastening socket 41 of the wheel 1, pull the cover plate 21 in the clockwise direction, and the lower end of the cover plate 21, fixed by the connecting shaft pin, begins to rotate along the central axis of the connecting shaft pin. When the pin body 22 on the cover plate 21 moves to the alignment position of the fastening socket 41, the pin body 22 on the cover plate 21 is inserted into the fastening socket 41 and fixed. In this way, a complete adjustment of the window 12 is completed. If it is necessary to continue to increase the coverage of the window 12, the upper pin body 22 can be continued to be removed from the fastening socket 41, and the adjustment can be continued in the aforementioned manner, that is, a new window 12 reduction adjustment can be completed, and vice versa, the window 12 enlargement adjustment process.

[0085] The present invention uses a manual adjustment method to adjust the window opening, which can reduce the use of electrical parts and reduce the cost of the opening adjustment mechanism.

[0086] When the window 12 of the wheel 1 is adjusted to be smaller, the air flow passing through the window 12 of the wheel 1 is effectively reduced when the vehicle is driving, which reduces the air resistance of the wheel 1, thereby reducing the air resistance of the entire vehicle during driving, and ultimately achieving fuel-saving performance.

[0087] Some special appearance patterns are designed on the cover plate 21. When the window 12 becomes smaller, the pattern is displayed, which can increase the appearance texture of the side of the vehicle. If the side appearance of the vehicle needs to be adjusted, it can be replaced by making a cover plate 21 with a different pattern. Compared with the traditional way of developing a new wheel 1 solution, this saves costs such as mold opening and performance verification and can shorten the development cycle, ultimately achieving the diversity of appearance and the economy of appearance development.

[0088] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
