Description

Technical Field

[0001] This utility model relates to vehicle wheels, specifically to a low-drag wheel and a vehicle. Background Technology

[0002] Overall vehicle range is a pain point for new energy vehicles. Vehicles need to overcome air resistance when traveling at high speeds, and low-drag wheels can help reduce this resistance. Low-drag aluminum wheels (low-drag aluminum alloy wheels) are widely used, reducing wheel weight, decreasing rotational inertia, and reducing airflow turbulence during wheel rotation by minimizing the open area of ​​the wheel (such as petal-shaped or five-spoke closed designs). Currently, most low-drag aluminum wheels are made of a single pure aluminum alloy material, resulting in a relatively rugged design. Existing technologies also use wheel covers that snap together with the low-drag aluminum wheel, further reducing the open area; however, the reliability of this snap-on wheel cover connection is not high. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a low wind resistance wheel and vehicle, which can reduce the wind resistance of the wheel to the whole vehicle, increase the vehicle's range, improve connection reliability, prevent non-metallic sealing parts from falling off due to high-speed rotation of the wheel, and is relatively easy to disassemble and assemble.

[0004] This utility model discloses a low-drag wheel, comprising a wheel body and a plurality of non-metallic sealing components. The wheel body has a plurality of first ventilation openings spaced apart along its circumference, and each of the non-metallic sealing components seals each of the first ventilation openings. Each of the non-metallic sealing components includes a sealing plate body and a plurality of connecting supports, which are spaced apart on the side of the sealing plate body facing the first ventilation opening. Each of the first ventilation openings has a plurality of mounting supports. Each mounting support corresponds one-to-one with each of the connecting supports, and the two are connected by threaded fasteners.

[0005] Furthermore, the connecting support includes an annular column and a nut. A limiting ring is provided inside the annular column, and a cavity is formed between the limiting ring and the sealing plate body. The nut is located on the side of the limiting ring away from the cavity.

[0006] Furthermore, an annular groove is provided in the middle of the outer surface of the nut, and the interior of the annular column conformally fits the outer surface of the nut.

[0007] Furthermore, the sealing plate body is provided with decorative textures.

[0008] Furthermore, the wheel body includes a rim and multiple spokes, the multiple spokes being equally spaced circumferentially within the rim, and each spoke being provided with the first vent and the mounting bracket.

[0009] Furthermore, a limiting groove is provided in the middle of the mounting bracket. The limiting groove is recessed into the mounting bracket in a direction away from the connecting bracket. The limiting groove forms a planar support part and an annular limiting part. The planar support part abuts against the connecting bracket, and the annular limiting part surrounds the outside of the connecting bracket.

[0010] Furthermore, a through hole is provided in the middle of the limiting groove, through which the threaded fastener passes and connects to the connecting support.

[0011] Furthermore, each of the spokes is provided with a second vent, and a third vent is provided between two adjacent spokes.

[0012] Furthermore, the wheel body is made of aluminum alloy, and the non-metallic sealing component is made of plastic.

[0013] One type of vehicle in this invention includes the aforementioned low-drag wheels.

[0014] The beneficial effects of this utility model are: (1) This utility model uses multiple non-metallic sealing components to seal the multiple first ventilation openings hollowed out on the wheel body, which can reduce the ventilation area of ​​the wheel body, thereby reducing the wind resistance of the wheel to the whole vehicle and increasing the vehicle's range.

Detailed Implementation

[0019] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-5 As shown, a low-drag wheel in this embodiment includes a wheel body 1 and multiple non-metallic sealing components 2. The wheel body 1 has multiple first ventilation openings 101 spaced circumferentially, and each non-metallic sealing component 2 seals each of the first ventilation openings 101. Each non-metallic sealing component 2 includes a sealing plate body 201 and multiple connecting supports 202. The multiple connecting supports 202 are spaced apart on the side of the sealing plate body 201 facing the first ventilation opening 101. Each first ventilation opening 101 has multiple mounting supports 102. Each mounting support 102 corresponds one-to-one with each connecting support 202, and the two are connected by threaded fasteners 3. In this embodiment, the wheel body 1 is made of aluminum alloy, and the non-metallic sealing components 2 are made of plastic. The number of non-metallic sealing components 2 and first ventilation openings 101 can be five or more. Preferably, each non-metallic sealing component 2 has three or more connecting supports 202.

[0021] By sealing the multiple first ventilation openings 101 hollowed out on the wheel body 1 with multiple non-metallic sealing parts 2, the ventilation area of ​​the wheel body 1 can be reduced, thereby reducing the wind resistance of the wheel to the whole vehicle and increasing the vehicle's range. Furthermore, compared to the technical solution of reducing wind resistance by using a one-piece metal sealing plate for the wheel body 1, the non-metallic sealing parts 2 have a lower density. By replacing some of the metal material of the wheel body 1 with non-metallic sealing parts 2, the overall weight can be reduced while lowering the wheel's wind resistance, thus further increasing the vehicle's range.

[0022] The non-metallic sealing component 2 is injection molded, resulting in a richer shape and more specific details, which can improve the aesthetics of the wheel.

[0023] By fixing the non-metallic sealing part 2 to the wheel body 1 with threaded fasteners 3, the connection reliability can be improved, the non-metallic sealing part 2 can be prevented from falling off due to the high speed rotation of the wheel, and the disassembly and assembly are relatively simple.

[0024] In this embodiment, the connecting support 202 includes an annular column 2021 and a nut 2022. A limiting ring 2024 is provided inside the annular column 2021. A cavity 2025 is formed between the limiting ring 2024 and the sealing plate body 201. The nut 2022 is disposed on the side of the limiting ring 2024 away from the cavity 2025.

[0025] The nut 2022 can be made of copper. As an insert, the nut 2022 is embedded in the annular column 2021 through in-mold injection molding, becoming an integral part of the sealing plate body 201. A cavity 2025 is formed between the limiting ring 2024 and the sealing plate body 201. There is a certain distance between the nut 2022 and the sealing plate body 201, which can prevent shrinkage marks from forming on the surface of the sealing plate body 201 during injection molding and cooling, thereby ensuring the aesthetic appearance of the sealing plate body 201.

[0026] In this embodiment, an annular groove 2023 is provided in the middle of the outer surface of the nut 2022, and the interior of the annular column 2021 conformally fits the outer surface of the nut 2022. The outer surface of the nut 2022 refers to the outer surface of the nut 2022 in its circumferential direction. The annular groove 2023 in the middle of the nut 2022 can conformally fit the annular column 2021 after injection molding, increasing the stability of the nut 2022 and the annular column 2021.

[0027] In this embodiment, the sealing plate body 201 is provided with a decorative texture 2011. The non-metallic sealing part 2 is formed by injection molding. By providing the decorative texture 2011 on the side facing outwards from the vehicle, the shape can be richer and the details more specific, which can improve the aesthetics of the wheel.

[0028] In this embodiment, the wheel body 1 includes a rim 103 and a plurality of spokes 104. The plurality of spokes 104 are equally spaced along the circumference within the rim 103. Each spoke 104 is provided with a first vent 101 and a mounting bracket 102.

[0029] In this embodiment, a limiting groove 1021 is provided in the middle of the mounting support 102. The limiting groove 1021 is recessed in the mounting support 102 in a direction away from the connecting support 202. The limiting groove 1021 forms a planar support portion 1022 and an annular limiting portion 1023. The planar support portion 1022 abuts against the connecting support 202, and the annular limiting portion 1023 surrounds the outside of the connecting support 202.

[0030] The end face of the nut 2022 facing the mounting support 102 is flush with the end face of the annular column 2021, forming a flat end face of the connecting support 202. The connecting support 202 is inserted into the limiting groove 1021, and the end face of the connecting support 202 abuts against the planar support portion 1022 of the limiting groove 1021, forming a surface-to-surface contact. The cylindrical surface of the annular column 2021 of the connecting support 202 is surrounded by the annular limiting portion 1023, which can constrain the position of the connecting support 202 during assembly. The three connecting supports 202 on each non-metallic sealing part 2 are respectively inserted into the corresponding limiting groove 1021, so that the inner hole of the nut 2022 of each connecting support 202 is aligned with the position of the through hole 1024 of the corresponding limiting groove 1021, so as to facilitate subsequent connection by threaded fasteners 3, thereby making the assembly simpler.

[0031] In this embodiment, a through hole 1024 is provided in the middle of the limiting groove 1021, and the threaded fastener 3 passes through the through hole 1024 and is connected to the connecting support 202.

[0032] The threaded fastener 3 passes through the through hole 1024 from one side of the wheel body 1 and is connected to the nut 2022 in the connecting support 202. This allows the threaded fastener 3 to be hidden inside the wheel body 1 without affecting the appearance of the sealing plate body 201.

[0033] In this embodiment, each of the spokes 104 is provided with a second vent 105, and a third vent 106 is provided between two adjacent spokes 104. The second vents 105 and the third vents 106 enable the wheel body 1 to retain a certain amount of ventilation capacity to dissipate heat from the braking device. By blocking part of the vents with the non-metallic sealing member 2, the ventilation area can be reduced, and the wind resistance can be reduced. By retaining part of the vents, a certain amount of heat dissipation capacity can be retained while reducing wind resistance.

[0034] One vehicle in this embodiment includes the aforementioned low-drag wheels.

[0035] The vehicles can be, but are not limited to, pure electric vehicles (PEV / BEV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), new energy vehicles, and gasoline vehicles.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
