For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the inside of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] like Figures 1 to 4As shown, the present invention provides a three-dimensional wheel, including a spoke 100 and a rim 200; the outer ring 101 of the spoke 100 is connected to the rim 200; the spoke 100 includes a plurality of spokes 103 and a mounting surface 102, the plurality of spokes 103 are arranged at intervals along the circumference of the mounting surface 102, one end of the spoke 103 is connected to the mounting surface 102, and the other end is connected to the outer ring 101; the spoke 103 includes a plane section 104 and a flange 105, the flange 105 is connected to both sides of the plane section 104, and the flange 105 is connected to the outer ring 101; The edge 105 and the plane segment 104 form a chamfer 106 at the connection, the line between the endpoints of the chamfer 106 away from the plane segment 104 is W, the length of W is a, the line between the end of the flange 105 away from the plane segment 104 is W1, the length of W1 is b, the perpendicular line between the line W and the line W1 is W2, the length of W2 is h, the angle between the perpendicular line W2 and the flange 105 is α, wherein h=(ba) / 2tanα, and the length a of the line W is in the range of 1 mm to 15 mm.

[0035] In this embodiment, the three-dimensional wheel includes a spoke 100 and a rim 200, wherein an outer ring 101 of the spoke 100 is connected to the rim 200, the spoke 100 includes a mounting surface 102 and a plurality of spokes 103, the plurality of spokes 103 are arranged at intervals along the circumference of the mounting surface 102, and the spoke 103 includes a plane section 104 and a flange 105, the flange 105 and the plane section 104 form a chamfer 106 at the connection, the flanges 105 on both sides of the plane section 104 are symmetrically arranged at both ends of the one-sided section 104, so that the plane section 104 and the flanges 105 on both sides thereof are an isosceles trapezoid as a whole, and can be symmetrical along the centerline axis of the plane section 104, and the three-dimensional shaping of the wheel 400 is enhanced by the design of the plane section 104 and the flange 105. By limiting the length a of the line W between the endpoints of the chamfer 106 away from one end of the plane segment 104 within the range of 1mm to 15mm, and by setting the angle α between the line W1 between the end of the flange 105 away from the plane segment 104 and the perpendicular line W2 and the flange 105, the length h of the line W and the perpendicular line W2 between the line W1 can be limited, that is, h=(ba) / 2tanα. The above limitation can not only ensure the welding contact surface area between the spoke 100 and the rim 200, but also improve the welding stability between the two, so as to achieve the effect of improving the strength of the spoke 100, etc., and ensure the comfort of the wheel 400, but also increase the diversity of the three-dimensional shape of the wheel 400, making the shape more beautiful.

[0036] A chamfer 106 is formed between the plane section 104 and the flanges 105 on both sides thereof, and the radius of the chamfer 106 increases with the increase in the width between the flanges 105 on both sides of the plane section 104, that is, the larger the width between the flanges 105, the flatter the two flanges 105 will become, thereby increasing the radius of the chamfer 106, thereby reducing the stress concentration of the chamfer 106, and therefore the width between the flanges 105 is limited as mentioned above.

[0037] Preferably, the spokes 103 can be designed to be hollow in order to reduce their own weight. Accordingly, they are made of magnesium, aluminum or other metal materials. During the manufacturing process, they are heated and formed, then pressurized and cooled, and finally made by laser cutting.

[0038] According to an embodiment provided by the present invention, Figure 1 and Figure 4 As shown, the length b is in the range of 1 to 10 times the length a, and the angle α is in the range of 5° to 60°.

[0039] In this embodiment, the length b is in the range of 1 to 10 times the length a, that is, the length a<b<10a, and the angle α is in the range of 5° to 60°, so that when the angle α is 5°, the value of tanα is the smallest, and when the angle α is 60°, the value of tanα is the largest. Since the length h of the vertical line W2 satisfies the formula h=(ba) / 2tanα, when the angle α is 5° and the length b is 10 times the length a, the length h of the vertical line W2 reaches the maximum value, that is, the maximum value of the length h is (10a-a) / 2t an5°, that is, 4.5a / tan5°. Since the length a ranges from 1mm to 15mm, the maximum value of the length h is 67.5 / tan5°mm. By limiting the length b to be in the range of 1 to 10 times the length a and the angle α to be in the range of 5° to 60°, the length h can be in the range of 0 to 67.5 / tan5°mm, thereby ensuring the welding contact surface area between the spoke 100 and the rim 200 while increasing the diversity of the three-dimensional shape of the wheel 400, making the shape more beautiful.

[0040] When the angle α is 60°, the value of tanα is the largest, that is, the value range of the length h is the smallest at this time, that is, the value of the length h must be greater than (ba) / 2tan60°. The value of the length h is specifically obtained through actual usage requirements, that is, the demand for the three-dimensional shape of the wheel 400 and the limitation of the length b, so that the wheel 400 is more three-dimensional and the shape is more beautiful.

[0041] According to an embodiment provided by the present invention, Figure 1As shown, two adjacent spokes form a spoke group, and multiple spoke groups are arranged at intervals along the circumference of the mounting surface 102 . Adjacent spoke groups or spokes 103 , the mounting surface 102 , and the outer ring 101 enclose a shaping area 300 .

[0042] Furthermore, the shaping area 300 includes a first air hole 301 and a second air hole 302; the ends of two adjacent groups of spokes are connected by a first transition portion 107, and the two adjacent groups of spokes, the mounting surface 102, and the outer ring 101 form the first air hole 301; the ends of the two spokes 103 in each group of spokes located at the mounting surface 102 are connected by a second transition portion 108, and the second transition portion 108 and the spokes 103 in each group of spokes and the outer ring 101 form the second air hole 302.

[0043] In this embodiment, two adjacent spokes form a spoke group, and the multiple spoke groups are arranged at intervals in the circumferential direction of the mounting surface 102, that is, the mounting surface 102 is respectively fixed to one end of each spoke 103 in each spoke group, and the other ends of the spokes 103 are fixed to the outer ring 101, so that the two adjacent spoke groups, the mounting surface 102 and the outer ring 101 are enclosed to form a first air hole 301. Under the premise of ensuring welding reliability and welding stability, the thickness of the outer ring 101 is limited to increase the design space of the first air hole 301 as much as possible. By increasing the design space of the first air hole 301, the weight of the wheel 400 can be effectively reduced, and the overall aesthetics of the wheel 400 can also be improved. The second transition portion 108 and the spokes 103 in each spoke group and the outer ring 101 form a second air hole 302, wherein preferably, the design space of the second air hole 302 increases as the design space of the first air hole 301 increases, that is, the design space of the second air hole 302 shows the same change trend as the design space of the first air hole 301.

[0044] The first air hole 301 and the second air hole 302 together constitute the modeling area 300. While ensuring welding reliability and welding stability, the design area of ​​the modeling area 300 is increased as much as possible by limiting the thickness of the outer ring 101, the length from the first transition portion 107 to the inner wall of the outer ring 101, and the length from the outer edge of the middle hole 110 to the inner wall of the outer ring 101. This allows the first air hole 301 and the second air hole 302 to have more design space, thereby ensuring the diversity of the three-dimensional design of the wheel 400.

[0045] Preferably, the first air hole 301 is V-shaped, and the second air hole 302 is U-shaped.

[0046] In this embodiment, preferably, the first transition portion 107 and the spokes 103 on both sides thereof present a V-shaped design, and the second transition portion 108 and the spokes 103 on both sides thereof present a U-shaped design, that is, by designing the first air hole 301 as a V-shape and the second air hole 302 as a U-shape, not only the stability of the spoke 100 can be increased, but also the overall aesthetics of the wheel 400 can be increased.

[0047] According to an embodiment provided by the present invention, Figure 1 As shown, the radius of the wheel 400 is L, the thickness of the outer ring 101 is D, D / L*100%=X, 6%≤X≤20%.

[0048] In this embodiment, the radius of the wheel 400 is L, the thickness of the outer ring 101 is D, D / L*100%=X, 6%≤X≤20%, the thickness of the spoke 100 will directly affect the welding area and welding stability between the spoke 100 and the rim 200, and also affect the designable area of ​​the styling area 300. When the ratio X between the thickness of the spoke 100 and the radius of the wheel 400 is in the range of 6% to 20%, the welding contact surface area between the spoke 100 and the rim 200 can be effectively guaranteed, and then the welding stability between the two can be improved, so as to achieve the effect of improving the lateral stiffness and strength of the spoke 100, ensure the comfort of use of the wheel 400, and at the same time increase the diversity of the three-dimensional shape of the wheel 400.

[0049] Preferably, the ratio X between the thickness of the spoke 100 and the radius of the wheel 400 is in the range of 6% to 20%. For example, when the ratio X is 9%, the radius L of the wheel 400 provided in this embodiment is 250 mm, and the thickness D of the outer ring 101 of the spoke 100 is 22.5 mm. This setting can ensure the welding contact surface area between the spoke 100 and the rim 200, thereby achieving the overall effect of improving the lateral stiffness (elasticity) and strength of the spoke 100.

[0050] According to an embodiment provided by the present invention, Figure 1 As shown, the length between the first transition portion 107 and the inner wall of the outer ring 101 is L1, the length between the outer edge of the center hole 110 at the center of the mounting surface 102 and the inner wall of the outer ring 101 is L2, L1 / L2*100%=Y, 0≤Y≤75%.

[0051] In this embodiment, the length between the first transition portion 107 and the inner wall of the outer ring 101 is L1, and the length between the outer edge of the center hole 110 and the inner wall of the outer ring 101 is L2. Preferably, when the ratio of the length L1 to the length L2 is in the range of 0% to 75%, the edge strength of the first air hole 301 and the strength of the mounting surface 102 can be ensured, thereby improving the safety of the wheel 400.

[0052] Among them, the cross-sectional area of ​​the first air hole 301 increases with the increase of the ratio Y. The design space of the first air hole 301 is controlled by controlling the size of the ratio Y, thereby increasing the designability of the first air hole 301. Increasing the design space of the first air hole 301 can also effectively reduce the weight of the wheel 400. However, the ratio Y cannot be too large. If it is too large, the area of ​​the mounting surface 102 will be insufficient to meet the usage requirements. Therefore, preferably, the ratio Y is suitable in the range of 0% to 75%.

[0053] For example, when the length L2 is 192.00 mm, when the ratio Y is 75%, the length L1 is 144.00 mm, that is, the inner ends of the two spokes 103 extend to the edge (intersection) of the mounting surface 102, and the first transition portion 107 is located at the edge (intersection) of the mounting surface 102. At this time, the design space of the first air hole 301 is the maximum value, which can greatly reduce the weight of the wheel spoke 100; when the ratio Y is 55%, the length L1 is 105.6 mm, and the spokes 103 of the two adjacent spoke groups are close to the intersection end 11 of the spoke group. 3, a first transition portion 107 is provided between the spokes 100 and the spoke group 3, the first transition portion 107 extends radially to the spoke group intersection end 113, the first transition portion 107 connects the edges of the two spokes 103, reduces the weight of the spoke 100, and improves the edge strength of the first wind control to avoid cracking of the wind hole; when the ratio Y is 0%, the length L1 is 0mm, which is equivalent to not having the first wind hole 301, and the weight of the spoke 100 reaches the maximum value; in summary, when the length L2 is 192.00mm, the range of the length L1 is between 0 and 145.5mm.

[0054] According to an embodiment provided by the present invention, Figure 1 , Figure 2 and Figure 3 As shown, an extension rib 109 is further provided at the connection between two adjacent spoke groups, one end of the extension rib 109 is connected to the middle hole 110 , and the other end is connected to the first transition portion 107 .

[0055] In this embodiment, two adjacent groups of spokes are connected to the center hole 110 at the connection point through an extension rib 109. Preferably, the ends of the two adjacent groups of spokes are connected through a first transition portion 107 to achieve the effect of connecting the ends of the two adjacent groups of spokes together.

[0056] According to an embodiment provided by the present invention, Figure 1 As shown, a screw hole seat 111 is provided between two adjacent extension ribs 109 , and a screw hole 112 is provided on the screw hole seat 111 . The screw hole 112 is used to connect the wheel 400 to the vehicle body.

[0057] In this embodiment, a screw hole seat 111 is provided between two adjacent extension ribs 109, and a screw hole 112 is opened on the screw hole seat 111. The screw hole 112 can facilitate direct connection between the wheel 400 and the vehicle body, and can be fixed to the vehicle body by passing a bolt through the screw hole 112.

[0058] According to an embodiment provided by the present invention, Figure 1 and Figure 3 As shown, the plane section 104 and the flanges 105 on both sides thereof enclose a cavity.

[0059] In this embodiment, the flanges 105 are respectively connected to both sides of the plane section 104, and the flanges 105 and the plane section 104 enclose a cavity. The larger the width of the plane section 104, the less stress concentration of the spokes 103 in the plane section 104 can be. However, the plane section 104 is directly related to the three-dimensional effect of the spoke 100, that is, the larger the width of the plane section 104, the lower the three-dimensional effect of the spoke 100 will be. The smaller the width of the plane section 104, the greater the stress concentration will be. Therefore, under the premise of avoiding excessive stress concentration, the width of the plane section 104 needs to be limited to a range of 1 mm to 15 mm, and the maximum width of the cavity is within a range of 1 to 10 times the width of the plane section 104, so as to effectively improve the three-dimensional modeling effect of the spoke 100.

[0060] The above are only preferred embodiments of the present invention and are 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.
