Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle wheels, in particular to a low wind resistance vehicle wheel assembly and a vehicle with the same. BACKGROUND

[0002] When a vehicle is running, it is subjected to external air resistance, in which the aerodynamic resistance of the wheel cavity is an important part of the entire air resistance.

[0003] The wheel mainly rotates during running, and a relatively complex airflow is formed around the wheel, which ultimately affects the wind resistance of the entire vehicle.

[0004] In the prior art, if a decorative cover is installed on the wheel, the decorative cover is usually of a closed structure and fixed, and the gap between the spokes is always closed, which can reduce the airflow passing through the spokes, make the airflow at the front of the vehicle flow more to the rear of the vehicle, reduce the airflow inside the wheel cavity, and achieve 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 requirement 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.

The durable automobile wheel decorative cover can fix the protection cover, the first frame, the decorative frame and the outer wall of the automobile wheel through the first bolt, thereby enhancing the firmness of the wheel decorative cover, preventing external particles from entering the first frame, blocking some large particles and impurities through the ventilation holes, and circulating the air through the cooperation between the supporting rods, springs and sleeve columns, thereby achieving the effect of shock absorption. The spring has good shock absorption and shock resistance.

[0038] The specific embodiments of the application are further described in detail below by comparing the drawings and through the description of the optimal embodiments.

[0039] A low-drag wheel assembly includes a wheel 1, the wheel 1 including a wheel body 11, and a window 12 provided on the wheel body 11; the window 12 is provided with an opening adjustment mechanism 2; the low-drag wheel assembly disclosed in this invention can control the opening of the window 12 as needed by setting the opening adjustment mechanism 2, thereby changing the running resistance of the wheel 1 as needed.

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

[0041] The opening adjustment mechanism 2 in this invention can be configured to either close the spoke gap during vehicle operation or expose the spoke gap when the vehicle is braking, thus meeting different usage requirements according to different working conditions.

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

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

[0044] In this 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 to control the opening of the window 12 during actual use.

[0045] Specifically, the opening adjustment mechanism 2 in this invention 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 near the side of the vehicle body.

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

[0047] In addition, the cover plate 21 in this invention includes multiple individual plates 211, which are stacked sequentially; the cover plate 21 in this invention is similar to a fan design; this facilitates the opening and closing of the cover plate 21 and makes it convenient for practical use.

[0048] In this invention, one end of each of the individual panels is connected by a connecting component. The connecting component facilitates the connection between the individual panels, similar to the connection method at the bottom of a fan. Similarly, to facilitate the opening of the cover 21, adjacent individual panels can rotate relative to each other around the connecting component. This arrangement facilitates the opening and closing control of the cover 21.

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

[0050] In this invention, the connecting pin 23 can also serve as a pivot, facilitating the rotation of the single plate 211 on the connecting pin 23 during subsequent use. In addition, in this invention, the through hole 24 on the single plate and the connecting pin 23 can be connected by an interference fit. For example, a rubber layer can be provided on the inner wall of the through hole 24. This arrangement can ensure the stable connection of the single plate on the connecting pin 23, while also facilitating the subsequent rotation operation of the single plate on the connecting pin 23.

[0051] In addition, in this invention, the connecting pin 23 can be fixedly connected to the wheel body 11, or it can be designed to be rotatable as needed. The specific choice can be made according to the requirements.

[0052] Furthermore, the connecting component in this invention also includes a support block 3 disposed at the 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; the support block 3 has two functions in this invention. The support block 3 is distributed at the corners of the window 12, mainly arranged at the connection of adjacent spokes 14, which plays a good role in reinforcement and ensures the structural strength of the connection of adjacent spokes 14. At the same time, the support block 3 provides 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 this invention, two adjacent single plates 211 are connected by a linkage mechanism. The linkage mechanism ensures the linkage between the single plates 211. In subsequent use, the linkage mechanism can not only guide the movement between adjacent single plates 211, but also facilitate the linkage between the single plates 211 by limiting the opening method of the hanging groove 212.

[0054] The linkage mechanism described in this invention includes a hooking protrusion on one of the individual plates 211 and a hooking groove 212 on the other individual plate 211; the hooking protrusion in each linkage mechanism is connected to the corresponding hooking groove 212; this arrangement makes the linkage mechanism and the connecting pin shaft act as two connection points, which better ensures the stability of the movement of adjacent individual plates 211 and the stability of the connection.

[0055] Meanwhile, the hanging groove 212 described in this invention is an arc-shaped groove; the center of the arc-shaped groove is arranged concentrically with the center of the connecting pin 23. This arrangement can avoid the linkage mechanism from affecting the relative operation between adjacent single plates 211.

[0056] In addition, in this invention, the hanging groove 212 is connected to the side of the single plate 211 on only one side. This arrangement makes the side wall of the hanging groove 212 form a limiting protrusion, thereby cooperating with the hanging protrusion to realize the linkage between the single plates 211.

[0057] In this invention, the cover plate 21 is connected to the wheel body 11 by a fastening mechanism. The fastening mechanism is mainly used for the fastening installation of the cover plate 21 on the wheel body 11.

[0058] In addition, the fastening mechanism described in this invention includes a support guide rib 4 disposed on the side of the window 12 near the rim of the wheel 1 and an upper pin 22 disposed on the cover plate 21; the support guide rib 4 is provided with a fastening insertion hole 41; in this invention, the support guide rib 4 acts as a reinforcing rib, which can well ensure the structural strength of the area of ​​the window 12 near the rim 13; in addition, the support guide rib 4 also plays a good supporting and elevating role, preventing deformation of the end of the single plate 211 away from the connecting pin 23.

[0059] In addition, in this invention, the cover plate 21 is connected to the fastening hole 41 on the support guide rib 4 via the upper pin 22; the upper pin 22 acts as a plug-in post, and in subsequent use, it is inserted into the fastening hole 41 corresponding to the support guide rib 4, thereby realizing the locking and fixing of the end of the cover plate 21 away from the connecting pin 23.

[0060] Furthermore, the supporting guide rib 4 in this invention is provided with a plurality of fastening holes 41; adjacent fastening holes 41 are spaced apart; at least one single plate 211 of the cover plate 21 is provided with an upper pin 22; through such a setting, this invention can conveniently ensure the stability of the connection between the cover plate 21 and the supporting guide rib 4, and through the setting of a plurality of fastening holes 41, the cover plate 21 can be locked and fixed at different opening degrees.

[0061] In addition, at least one of the individual plates 211 in the cover plate 21 described in this invention is provided with an upper pin 22. Generally, it is required that the individual plates 211 on both sides of the cover plate 21 have upper pins 22. In subsequent use, the positions of the individual plates 211 on both sides of the cover plate 21 can be limited. At the same time, with the setting of the linkage mechanism, after the positions of the individual plates 211 on both sides are limited, the positions of each individual plate 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 22 can be set on each individual plate 211. At the same time, to avoid this, an arc-shaped groove can be set on the corresponding individual plate 211 for avoidance. Of course, such a setting may increase the design difficulty of the cover plate, so generally the upper pin can be set on the individual plate closest to the supporting guide rib 4.

[0063] As a further optimization, a fitting guide edge 2111 is provided on the innermost single-unit plate. The fitting guide edge 2111 is a protrusion set on the corresponding single-unit plate. The fitting guide edge 2111 is set perpendicular to the corresponding single-unit plate and is arranged on the single-unit plate closest to the inner side of the wheel in the cover plate. The fitting guide edge 2111 is an arc-shaped plate structure and is fitted to the inner side of the supporting guide rib 4. In actual use, the fitting guide plate is located on the inner wall of the supporting guide rib 4, and the single-unit plate is located on the side of the supporting guide rib 4 closer to the outside of the vehicle. This kind of cooperation can further limit the position of the cover plate and ensure the stability of its position during operation and arrangement.

[0064] Furthermore, in this invention, a storage groove 201 is provided on the inner wall of the window 12, and the storage groove 201 is provided on the side of the spoke 14 in the wheel body 11; the storage groove 201 provides a good storage function, making it convenient to store the cover plate 21 after it has been retracted or extended, avoiding or reducing the exposed size of the cover plate 21, and reducing the impact of the cover plate 21 on the heat dissipation of the wheel 1.

[0065] Furthermore, in this invention, the end of the single plate 211 near the rim 13 of the wheel 1 is arc-shaped; this arrangement can prevent the single plate 211 from interfering with the wheel body 11 when it rotates; the center of the outer side of the single plate 211 and the center of the connecting pin 23 are at the same point.

[0066] In addition, in this 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 the excessive wind resistance formed in the window 12 when the vehicle is running.

[0067] A vehicle including the low-drag wheel assembly.

[0068] specific:

[0069] This invention discloses a low-drag wheel assembly. Based on the existing wheel 1 structure, this invention proposes a novel low-drag, highly versatile structural solution by ingeniously optimizing the structure of wheel 1 locally.

[0070] The low wind resistance wheel assembly disclosed in this invention mainly includes a rim 13, spokes 14, a window 12, and an opening adjustment mechanism 2 disposed in the window 12.

[0071] The opening adjustment mechanism 2 disclosed in this invention mainly includes a cover plate 21, which is designed to resemble 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 this invention mainly includes multiple individual plates 211. In subsequent use, by controlling the opening and closing of the multiple individual plates 211, the adjustability of the opening of the window 12 can be effectively realized. 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, save product development costs, and improve the appearance and economy of the whole vehicle.

[0073] In this invention, the cover plate 21 is composed of multiple individual plates. These individual plates can be freely unfolded and closed. The overall shape of the cover plate 21 is designed as a fan shape or other polygons. Structurally, the individual plates can be adjusted according to usage requirements to achieve different areas or sizes.

[0074] The lower end of the cover plate 21 is provided with a through hole 24 to connect with a connecting shaft pin. The connecting shaft pin constrains the single plate, allowing the single plate to rotate concentrically around the shaft pin in the through hole 24. The upper end of the cover plate 21 is provided with an upper pin 22, which is subsequently inserted into the corresponding fastening hole 41 to achieve the connection between the cover plate 21 and the wheel body 11.

[0075] In actual use, the upper pin 22 on the cover plate 21 is inserted into the corresponding fastening hole 41 to achieve the connection between the cover plate 21 and the wheel body 11; thereby allowing the cover plate 21 to unfold according to a certain fixed shape.

[0076] Connecting 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 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 unfolded or closed along the central axis of the connecting pin. The size and shape of the connection between the connecting pin and the wheel 1 are designed to match the hole on the support block 3. It can be designed as a circle or other polygons so that the cover plate 21 fits tightly in the lower through hole, thereby ensuring that the lower end of the cover plate 21 is fixed at the support block 3 of the window 12 of the wheel 1.

[0077] Upper pin 22: An interface of a certain size and shape is designed on the upper end of the single plate of the cover plate 21, which can be connected and fastened to one end of the upper pin 22, so that the single plate of the cover plate 21 and the upper pin 22 can rotate and move synchronously; the other end of the upper pin 22 is provided with a bayonet, the size of which is designed to allow it to pass smoothly through the fastening hole 41 on the wheel 1 and be tightly engaged, thereby achieving the function of fastening and locking the upper pin 22 to the wheel 1, and at the same time fixing the upper end of the cover plate 21.

[0078] The cover plate 21 is connected to the wheel body 11 via a fastening mechanism. The fastening mechanism includes a support guide rib 4 located on the side of the window 12 near the rim of the wheel 1 and an upper pin 22 located on the cover plate 21. The support guide rib 4 is provided with a fastening insertion hole 41. The cover plate 21 is connected to the fastening insertion hole 41 on the support guide rib 4 via the upper pin 22. A row of fastening insertion holes 41 is designed at the intersection of the bottom outer end of the rim 13 of the wheel 1 and the upper end of the window 12 of the wheel 1. These fastening insertion holes 41 are all designed with a fixed size and shape, which can be circular or other shapes that are suitable for the locking pin. The outer end of the fastening insertion hole 41 must be designed with a certain gradient opening so that the locking pin in the upper pin 22 can pass smoothly through the fastening insertion hole 41 and be fixed. The inner end of the fastening insertion hole 41 must also be designed with a certain gradient opening so that the locking pin in the upper pin 22 can be smoothly removed from the fastening insertion hole 41.

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

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

[0081] In addition, in this invention, the support block and the support guide ribs serve to limit the end of the cover plate, preventing the cover plate from warping during use.

[0082] The support block 3 disclosed in this invention is located at the lower end of the window 12 of the center plate of the wheel 1. Essentially, an extended boss is designed at the lower end of the window 12 of the center plate of the wheel 1, and a through hole is opened on the boss. It can be designed as a circle or other polygons to ensure a tight match with the connecting shaft pin.

[0083] The adjustment method and performance mechanism of the window 12 of the wheel 1 in this invention are as follows:

[0084] When adjusting the window 12 of wheel 1 to decrease, first remove the upper pin 22 on the cover plate 21 from the fastening hole 41 of wheel 1 by hand. Pull the cover plate 21 clockwise. Since the lower end of the cover plate 21 is fixed by the connecting shaft pin, it begins to rotate along the central axis of the connecting shaft pin. When the upper pin 22 of the cover plate 21 moves to the alignment position of the fastening hole 41, insert the upper pin 22 of the cover plate 21 into the fastening hole 41 and fix it. This completes a complete adjustment of the window 12. If it is necessary to continue to increase the coverage of the window 12, the upper pin 22 can be removed from the fastening hole 41 again and the adjustment can be continued in the above manner to complete a new adjustment to decrease the window 12. Conversely, the adjustment process of increasing the window 12 is completed.

[0085] This 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 wheel 1 is adjusted to be smaller, the airflow passing through the window 12 of wheel 1 during vehicle movement is effectively reduced. This reduces the air resistance of wheel 1, thereby reducing the overall air resistance of the vehicle during driving and ultimately achieving fuel-saving performance.

[0087] Designing special appearance patterns on the cover plate 21, which are displayed when the window 12 is smaller, can enhance the appearance quality of the entire side of the vehicle. If the appearance of the side of the vehicle needs to be adjusted, it can be replaced by making cover plates 21 with different patterns. Compared with the traditional method of developing new wheel 1 designs, this saves costs such as mold opening and performance verification and can shorten the development cycle, ultimately achieving diversity of appearance and economy of appearance development.

[0088] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
