[0041] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0042] Reference below Figure 1-Figure 7 A spoiler blade for a vehicle diffuser according to an embodiment of the present invention is described.

[0043] like Figure 1-Figure 7 As shown, the spoiler blade 100 includes a soft member 1 , and the soft member 1 provides a deformation portion 11 when the spoiler blade 100 rotates, and the deformation portion 11 of the soft member 1 forms a virtual rotation axis of the spoiler blade 100 .

[0044] Based on the certain flexibility of the soft part 1, a deformation part 11 is formed on the soft part 1. When the spoiler blade 100 is driven to rotate, the deformation part of the soft part 1 forms a virtual rotation axis, so that the spoiler blade 100 rotates with the virtual rotation axis as the rotation axis, thereby realizing dynamic rotation of the spoiler blade.

[0045] The virtual rotation axis refers to a virtual axis around which the spoiler blade 100 can be regarded as rotating when a force is applied to it. The virtual rotation axis is formed by the deformation of the deformation portion 11 of the soft part 1. When the deformation portion 11 is subjected to a force, it deforms so that the deformation portion 11 forms the virtual rotation axis of the spoiler blade 100. When the force disappears, the deformation portion 11 can return to its original state.

[0046] For example, the soft part 1 may be made of rubber material. The rubber material has strong elasticity and flexibility, can recover to its original shape after deformation, and is suitable for processing on the spoiler blade 100.

[0047] Therefore, the spoiler blade 100 of the present application adopts the soft part 1. When the spoiler blade 100 rotates, the deformation part 11 of the soft part 1 is deformed to form a virtual rotation axis, so that the spoiler blade 100 rotates around the virtual rotation axis. When the spoiler blade 100 is applied to a vehicle diffuser, there is no need to reserve installation space at the rear of the vehicle.

[0048] Furthermore, a groove 12 is provided on at least one side surface of the deformation portion 11 , and a virtual rotation axis is formed at the groove 12 when the spoiler blade 100 rotates.

[0049] In this way, at least one side surface of the deformation portion 11 is thickened to form a groove 12, which guides the virtual rotation axis position of the spoiler blade 100 to be fixed at the deformation portion 11, and also enables the soft part 1 to be easily deformed at the groove 12, so that a virtual rotation axis can be formed at the groove 12 when the spoiler blade 100 rotates. Figure 2 and Figure 3 As shown, the groove 12 extends to both ends of the deformation portion 11, which facilitates the deformation portion 11 to deform more easily when subjected to a force.

[0050] Furthermore, when the deformation portion 11 is not deformed, the notch wall of the groove 12 is in an arc shape.

[0051] So, see Figure 3 As shown, when the deformation portion 11 is not deformed, the cross-sectional area of ​​the notch wall of the groove 12 is in the shape of an arc, and the arc has a center. When the deformation portion 11 is deformed, the spoiler blade 100 can be rotated around the virtual axis where the center of the circle is located, thereby improving the movement stability of the spoiler blade 100.

[0052] Further, the slot wall is symmetrical about an axis forming a virtual rotation axis.

[0053] In this way, when the deformation portion 11 is deformed by an external force, the spoiler blade 100 rotates around the symmetrical notch wall, so that the spoiler blade 100 is relatively stable when rotating clockwise or counterclockwise.

[0054] Further, see Figure 3 As shown, grooves 12 are formed on both side surfaces of the deformation portion 11 in the thickness direction.

[0055] Such a configuration facilitates the spoiler blade 100 to rotate around the grooves 12 on both sides along the thickness direction of the deformation portion 11 , and can protect the two side surfaces of the deformation portion 11 in the thickness direction, thereby extending the service life of the spoiler blade 100 .

[0056] Further, the groove 12 located on the outer surface of the spoiler blade 100 is a first groove 1201 , and the groove 12 located on the inner surface of the spoiler blade 100 is a second groove 1202 . The notch size of the second groove 1202 is smaller than the notch size of the first groove 1201 .

[0057] Since the spoiler blades 100 of the vehicle diffuser are usually opened only when the vehicle is traveling at high speed, the frequency of use of the spoiler blades 100 when opened is lower than the frequency of use of the spoiler blades 100 when closed.

[0058] Based on this, when the spoiler blade 100 is closed, the first groove 1201 located on the outer surface of the spoiler blade 100 needs to be stretched and deformed, while the second groove 1202 located on the inner surface of the spoiler blade 100 needs to be compressed and deformed. Therefore, the slot size of the second groove 1202 is smaller than the slot size of the first groove 1201, which can well meet the above-mentioned operating conditions of the spoiler blade 100.

[0059] Furthermore, when the deformation portion 11 is not deformed, the projections of the symmetry axis of the notch wall of the second groove 1202 and the symmetry axis of the notch wall of the first groove 1201 in the thickness direction do not overlap.

[0060] Since the spoiler blade 100 rotates clockwise or counterclockwise around the virtual rotation axis formed by the deformation portion 11, when rotating clockwise, the spoiler blade 100 rotates around the virtual rotation axis formed by the second groove 1202 located on the inner surface of the spoiler blade 100. If the projections of the symmetry axis of the notch wall of the second groove 1202 and the symmetry axis of the notch wall of the first groove 1201 in the thickness direction overlap, then the first groove 1201 located on the outer surface of the spoiler blade 100 will have a large tensile deformation, which will lead to fatigue damage or even fracture problems after long-term repeated use. Similarly, the same is true when the spoiler blade 100 rotates counterclockwise.

[0061] Therefore, the fatigue service life of the deformation portion 11 can be improved by making the projections of the symmetry axis of the notch wall of the second notch 1202 and the symmetry axis of the notch wall of the first notch 1201 not overlap in the thickness direction.

[0062] Furthermore, when the deformation portion 11 is not deformed, the radius of the second groove 1202 is equal to the radius of the first groove 1201 .

[0063] In this way, the radius of the second groove 1202 is equal to the radius of the first groove 1201. When the spoiler blade 100 rotates clockwise or counterclockwise around the virtual axis formed by the deformation portion 11, the deformation amounts of the first groove 1201 and the second groove 1202 are roughly the same, and the first groove 1201 or the second groove 1202 will not be excessively deformed, which can also extend the service life of the spoiler blade 100.

[0064] Furthermore, the soft part 1 further comprises a fixing portion 13 , which is suitable for connecting with the base 200 of the vehicle diffuser or the body of the vehicle, and the deformation portion 11 is connected to a side of the fixing portion 13 away from the base 200 or the vehicle.

[0065] Thus, the fixing portion 13 is disposed on one side of the soft component 1 close to the base 200 of the vehicle diffuser or the vehicle body to be connected with the base 200 of the vehicle diffuser or the vehicle body, so that one end of the spoiler blade 100 is fixed and the other end is rotatable.

[0066] Furthermore, when the fixing portion 13 of the soft component 1 is connected to the base 200 of the vehicle diffuser or the vehicle body, the soft component 1 can be squeezed and matched with the base 200 or the vehicle body due to its flexible nature, thereby improving the connection strength.

[0067] Furthermore, the fixing portion 13 is provided with at least one protruding mounting portion 1301 , and the fixing portion 13 is connected to the base 200 or the vehicle body via the mounting portion 1301 .

[0068] Thus, the fixing portion 13 is provided with a protruding mounting portion 1301, so that the spoiler blade 100 is connected to the base 200 or the vehicle body through the mounting portion 1301. The installation is convenient, and since the soft part 1 has the characteristics of being deformable and restorable, the mounting portion 1301 is protruded, which can effectively ensure the reliability of the spoiler blade 100 when connected to the base 200 or the vehicle.

[0069] Furthermore, a mounting hole 1302 is formed on the mounting portion 1301, and a rigid bushing 14 is disposed in the mounting hole 1302, and the rigid bushing 14 is interference-fitted in the mounting hole 1302. Furthermore, the axial length of the rigid bushing 14 is smaller than the axial length of the mounting hole 1302.

[0070] In this way, the vehicle diffuser base 200 or the vehicle body is fixed by connecting members such as bolts through the rigid bushing 14. In addition, the axial length of the mounting hole 1302 is greater than the axial length of the rigid bushing 14, so that when the connecting member is used for fixing, the soft member 1 can be squeezed to a certain extent, and the spoiler blade 100 can be better fixed.

[0071] For example, the rigid bushing 14 may be a metal bushing, but is not limited thereto.

[0072] Furthermore, a protruding step portion 1303 is provided on one side of the fixing portion 13 away from the deformation portion 11 , and a surface of the step portion 1303 on one side in the thickness direction is flush with the outer surface of the spoiler blade 100 , and the step portion 1303 is suitable for connecting with the vehicle body.

[0073] Since a vehicle diffuser installed on the vehicle body may have a gap with the vehicle body, affecting the appearance, a step portion 1303 protruding toward the vehicle body is provided on the side of the fixing portion 13 away from the deformation portion 11, and one side surface of the step portion 1303 in the thickness direction is flush with the outer surface of the spoiler blade 100, so that the step portion 1303 is seamlessly connected with the vehicle body and the bottom remains coplanar.

[0074] Furthermore, the flexible component 1 further includes a rotating portion 15 , which is connected to a side of the deformable portion 11 away from the fixed portion 13 , and the rotating portion 15 can rotate around a virtual rotating axis formed by the deformable portion 11 .

[0075] Thus, under the condition that the soft part 1 has a certain rigidity, a rotating part 15 is provided on the side of the deformation part 11 away from the fixed part 13, so that when the spoiler blade 100 rotates, the rotating part 15 can rotate around the virtual rotation formed by the deformation part 11 to achieve the spoiler function. The rotating part 15 will not be deformed.

[0076] Furthermore, the spoiler blade 100 further includes: a rigid part 2, which is connected to the soft part 1, and the rotation of the rigid part 2 can drive at least part of the soft part 1 to rotate around the virtual rotation axis.

[0077] See Figure 2-Figure 6 As shown, the rigid part 2 and the soft part 1 are connected to form a spoiler blade 100. At the position on the soft part 1 where a rotating shaft is needed, the thickness of the soft part 1 is reduced to a specific thickness, thereby forming a virtual rotating shaft so that the rigid part 2 can rotate around the virtual rotating shaft of the soft part 1.

[0078] Further, along the direction from the soft part 1 toward the rigid part 2 , the surface of the soft part 1 on the side adjacent to the rigid part 2 extends obliquely toward the side where the rigid part 2 is located to the surface of the rigid part 2 .

[0079] Thus, the surface of the soft part 1 adjacent to the rigid part 2 is inclined toward the side where the rigid part 2 is located and extends to the surface of the rigid part 2 to form a coplanar relationship, thereby improving the integrity of the spoiler blade 100 and having good aesthetics.

[0080] Furthermore, the rigid part 2 and the soft part 1 are connected as a whole by plastic coating.

[0081] In the embodiment of the present application, the soft part 1 and the rigid part 2 are joined together by using a plastic coating process, so that the soft part 1 and the rigid part 2 form an integrated structure, thereby improving the overall consistency of the spoiler blade 100 .

[0082] Furthermore, the rigid component 2 is a carbon fiber component, and the soft component 1 is a rubber component.

[0083] In this way, the hardness of the carbon fiber part is much greater than that of the rubber part. When the vehicle is traveling at high speed, the external force it is subjected to is very large. At this time, the vehicle diffuser needs to open the spoiler blade 100 so that the rigid part 2 rotates around the virtual axis of the soft part 1, and the rigid part 2 will not be deformed, thereby realizing the spoiler function of the spoiler blade 100.

[0084] Furthermore, a blade mounting bracket 3 is provided on the inner surface of the spoiler blade 100 in the thickness direction, and at least one blade mounting seat 4 is provided on the blade mounting bracket 3 .

[0085] In this way, the spoiler blade 100 is provided with a blade mounting bracket 3, which can be glued to the spoiler blade 100 by adhesive. For example, before the gluing process, the gluing surface can be sandblasted by a sandblasting machine, and then a certain gap is left between the gluing surfaces, filled with epoxy resin glue, and then the gluing surfaces are fixed for no less than twelve hours using a tool. Among them, the blade mounting bracket 3 can be made of aluminum alloy material.

[0086] A blade mounting seat 4 is provided on the blade mounting bracket 3 , so that the spoiler blade 100 is drivingly connected to the driving unit 300 through the blade mounting seat 4 .

[0087] like Figure 2 The left spoiler blade 100 of the vehicle diffuser shown is relatively large in overall size. Three mounting holes 1302 are provided at one end of the soft part 1 , and two blade mounting seats 4 are provided on the blade mounting bracket 3 .

[0088] like Figure 5 The left second spoiler blade 100 of the vehicle diffuser shown is relatively small in overall size. Two mounting holes 1302 are provided at one end of the soft part 1 , and a blade mounting seat 4 is provided on the blade mounting bracket 3 .

[0089] Of course, the spoiler blade 100 may also be a whole structure, with one or more blade mounting brackets 3 disposed on the spoiler blade 100, and one or more blade mounting seats 4 disposed on each blade mounting bracket 3. The design may be made according to the size of the spoiler blade 100.

[0090] like Figure 7 The spoiler blade 100 for a vehicle diffuser is shown in two states of opening and closing, and the opening and closing angles of the spoiler blade 100 for a vehicle diffuser are approximately eighteen degrees.

[0091] The vehicle diffuser according to the embodiment of the second aspect of the utility model includes: a base 200, a driving unit 300 and a spoiler blade 100 for the vehicle diffuser, wherein the driving unit 300 is arranged on the base 200, one end of the spoiler blade 100 is connected to the base 200, and the other end of the spoiler blade 100 is drivingly connected to the driving unit 300.

[0092] Thus, when the spoiler blade 100 is applied to a vehicle diffuser, there is no need to reserve installation space at the rear of the vehicle, and processing and installation are convenient.

[0093] Furthermore, a mounting portion 1301 is provided on the soft part 1 of the spoiler blade 100 , and the spoiler blade 100 is connected to the base 200 via the mounting portion 1301 .

[0094] In this way, the spoiler blade 100 can be conveniently connected to the base 200 or the vehicle body through the mounting portion 1301 .

[0095] A vehicle according to an embodiment of the third aspect of the utility model includes a spoiler blade 100 for a vehicle diffuser or a vehicle diffuser.

[0096] Thus, by adopting the above-mentioned vehicle diffuser, there is no need to reserve installation space at the rear of the vehicle.
