Description

Technical Field

[0001] This utility model relates to a vehicle aerodynamic device, specifically a vehicle aerodynamic device with a larger adjustment angle to achieve higher stability.

[0002] This application claims priority to Chinese patent application filed on April 28, 2025, application number "202520824559X", entitled "Vehicle Disruptor". All of these are incorporated herein by reference. Background Technology

[0003] When a vehicle is in motion, it experiences air resistance. The air velocity above and below the vehicle is different, creating a pressure difference. If this pressure difference is upward, it will cause the car to lift up, affecting the vehicle's stability.

[0004] To address these issues, vehicles typically install a rear wing, or car spoiler, in the trunk area to provide downforce through aerodynamics, thereby improving vehicle stability.

[0005] For high-performance sports cars, a larger rear wing with a greater angle is needed to provide stability.

[0006] The existing technology uses a hinge structure, and the maximum height that the hinge structure can raise the spoiler and the maximum angle at which the spoiler can be opened are limited by the space provided along the length of the vehicle body.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0075] Example 1

[0076] See Figures 1 to 5This utility model provides a vehicle spoiler device, which includes a frame 1, a spoiler 2, and a spoiler pivoting drive mechanism. The frame 1 is directly or indirectly fixedly connected to the vehicle body. The first end of the spoiler 2 is pivotally supported on the frame 1 around a first axis 21. The spoiler pivoting drive mechanism is connected to the second end of the spoiler 2 to drive the spoiler 2 to pivot.

[0077] In this embodiment, the connection between the spoiler pivot drive mechanism and the second end of the spoiler 2 is called a floating hinge point because it floats during the pivoting process of the spoiler 2.

[0078] In this embodiment, the spoiler 2 is driven to rotate around the first axis 21 by a spoiler pivot drive mechanism, so that the spoiler 2 has different tilt angles, thereby generating downforce with different wind resistance on the driving vehicle.

[0079] This embodiment has fewer parts, is simple to manufacture, has low cost, is easy to control, and can achieve a larger lift angle and a larger change in wind pressure value.

[0080] In this embodiment, the hinge point corresponding to the first shaft 21 is fixed to the frame 1, which is fixedly connected to the vehicle body. The spoiler 2 can rotate around this point, thereby causing the center of gravity of the spoiler 2 to deviate from its original position center. In contrast, in the prior art, the equivalent pivot point of the spoiler rotation is below the spoiler, and the spoiler can move up and down in its original position or rotate around its original position center without deviating from it. Therefore, compared with the prior art, the spoiler 2 in this embodiment has a larger tilt angle.

[0081] In addition, in this embodiment, the first end of the spoiler 2 can be placed relative to the second end of the spoiler 2 on the front or rear side of the vehicle, so that the spoiler 2 can tilt forward or backward to meet more complex wind power requirements.

[0082] In one embodiment, combined with Figure 1 and Figure 2 As shown, the spoiler pivoting drive mechanism includes a long hinge 3, a first connecting rod 5, a second connecting rod 6, a lifting assembly 7, and a lifting drive mechanism 8. The middle portion of the long hinge 3 is pivotally mounted on the frame 1 around a second axis 4. The two ends of the first connecting rod 5 are hinged to the second end of the spoiler 2 and the first end 31 of the long hinge 3, respectively. The first end of the second connecting rod 6 is hinged to the second end 32 of the long hinge 3. The actuating end of the lifting assembly 7 is hinged to the second end of the second connecting rod 6. The lifting drive mechanism 8 is connected to the lifting assembly 7.

[0083] In this embodiment, the lifting drive mechanism 8 drives the lifting assembly 7 to move up and down, causing the spoiler 2 to pivot around the first axis 21.

[0084] In one embodiment, combined with Figure 2As shown, the first end 31 and the second end 32 of the long hinge 3 are located on both sides of the second shaft 4, respectively.

[0085] In this embodiment, the lifting component 7 is offset from the spoiler in the horizontal direction, which is suitable for vehicle body structures where there is insufficient space directly below the spoiler.

[0086] In some embodiments, combined with Figure 2 As shown, the first end 31 and the second end of the long hinge 3 are the two ends of the long hinge 3 along the length direction, respectively.

[0087] In one embodiment, the lifting assembly 7 includes a mounting cylinder 71, a lead screw 72 rotatably disposed within the mounting cylinder 71, and a lifting cylinder 74 whose lower end is disposed within the mounting cylinder 71 and can slide along the mounting cylinder 71. A lead screw nut 73 is connected to the lead screw 72. The lifting cylinder 74 is fixedly connected to the lead screw nut 73. The top end of the lifting cylinder 74 is the operating end of the lifting assembly 7.

[0088] In this embodiment, when the lead screw 72 rotates, it drives the lead screw nut 73 to rise and fall along the lead screw 72. The lifting cylinder 74 rises and falls along the lead screw 72 together with the lead screw nut 73.

[0089] In one embodiment, combined with Figure 4 and Figure 5 As shown, the lifting drive mechanism 8 includes a motor 81, a worm gear 82 coaxially connected to the output shaft of the motor 81, and a turbine 83 coaxially connected to the lead screw 72. The turbine 83 is connected to the worm gear 82 in a transmission connection.

[0090] In this embodiment, the turbine 83 and worm gear 82, together with the lead screw nut 73, convert the horizontal rotational motion output by the motor 81 into the vertical rotational motion of the lead screw 72.

[0091] It should be understood that the top end of the lead screw 72 is connected to an upper limit structure 75, and the bottom end is provided with a lower limit structure 76. The upper limit structure 75 and the lower limit structure 76 work together to limit the stroke of the lead screw nut 73 along the lead screw 72.

[0092] In some embodiments, combined with Figure 4 As shown, the device also includes a base 9, which is fixedly connected to the vehicle body. The frame 1 is installed above the base 9 to achieve a fixed connection between the frame 1 and the vehicle body.

[0093] In some embodiments, combined with Figure 4 and Figure 5 As shown, the device also includes a gearbox 11, with a worm gear 83 and a worm 82 disposed within the gearbox 11. The lower end of the mounting cylinder 71 is fixedly connected to the gearbox 11. In some embodiments, combined with Figure 5 As shown, the lower limit structure 76 is formed on the gearbox body 11.

[0094] To accommodate more vehicle models, in one embodiment, combined with Figure 3 and Figure 4 As shown, the device also includes a secondary spoiler 10, which is fixedly connected to the frame 1. It can be positioned in front of or behind the spoiler 2 as needed.

[0095] Example 2

[0096] In Embodiment 1, the first and second ends of the spoiler 2 are located below the spoiler body of the spoiler 2, respectively. Unlike Embodiment 1, the spoiler 2 in this embodiment is installed in a suspended manner at the rear of the vehicle; that is, the first and second ends of the spoiler 2 are located above the spoiler body of the spoiler 2, respectively. This installation method is suitable for situations where the spoiler is positioned further back at the rear of the vehicle or even suspended in mid-air.

[0097] The specific structure of the spoiler in this embodiment will be described below.

[0098] like Figure 6 As shown, the spoiler 2 includes: a spoiler body 22; and a first ear seat 23 and a second ear seat 24. The first ear seat 23 and the second ear seat 24 are respectively protruding upward and disposed on the spoiler body 22. The first end of the spoiler 2 is disposed on the first ear seat 23, and the second end of the spoiler 2 is disposed on the second ear seat 24.

[0099] Combination Figure 6 As shown, the difference between this embodiment and Embodiment 1 lies in that the spoiler pivoting drive mechanism includes: a linear reciprocating mechanism 12, including a mounting part 121 and an output part 122, the output part 122 being capable of linear reciprocating movement relative to the mounting part 121, the mounting part 121 being directly or indirectly fixedly connected to the frame 1; two or more long hinges 3, spaced apart between the output part 122 of the linear reciprocating mechanism 12 and the second end of the spoiler 2, each long hinge 3 including a first end 31, a second end 32 and a pivot point 33, the long hinge 3 being pivotally connected to the frame 1 through the pivot point 33; and a first connecting rod 5, an intermediate connecting rod 13 and a second connecting rod 6, the first connecting rod 5 being disposed on the spoiler 2. The second end is located between the second end and the first end 31 of the long hinge 3 closest to the spoiler 2, and one end of the first connecting rod 5 is hinged to the second end of the spoiler 2, and the other end is hinged to the first end 31 of the long hinge 3 closest to the spoiler 2; the second connecting rod 6 is located between the output part 122 of the linear reciprocating mechanism 12 and the long hinge 3 closest to the output part 122, and one end of the second connecting rod 6 is hinged to the output part 122 of the linear reciprocating mechanism 12, and the other end is hinged to the second end 32 of the long hinge 3 closest to the output part 122; an intermediate connecting rod 13 is provided between two adjacent long hinges 3, and the two ends of the intermediate connecting rod 13 are respectively hinged to the first end 31 and the second end 32 located between two adjacent long hinges 3.

[0100] The output part 122 of the linear reciprocating mechanism 12 moves linearly and reciprocally, driving the second link 6, which is transmitted to the intermediate link 13 through the long hinge 3 closest to the output part 122, and to the first link 5 through the long hinge 3 closest to the spoiler 2. The first link 5 drives the spoiler 2 to pivot.

[0101] Taking a structure with two long hinges 3 as an example, combined with... Figure 6 As shown, the two long hinges 3 are a forward motion long hinge 301 and a reverse motion long hinge 302, respectively. The forward motion long hinge 301 is the long hinge closest to the output part 122. Driven by the output part 122 of the linear reciprocating mechanism 12, the forward motion long hinge 301 rotates around the pivot point 33 in the first rotation direction, which drives the reverse motion long hinge 302 to rotate in the second rotation direction opposite to the first rotation direction, and applies force to the first connecting rod 5, so that the second end of the spoiler 2 rotates around the first axis 21 in the first rotation direction.

[0102] The linear reciprocating mechanism 12 in this embodiment can be a combination of the lifting drive mechanism 8 and the lifting component 7 in embodiment 1, or it can be an electric linear actuator.

[0103] In this embodiment, the mounting part 121 can be fixedly connected to the frame 1 by fastening screws, or it can be fixed by other existing methods.

[0104] Example 3

[0105] Combination Figure 7 and Figure 8 As shown, the difference between this embodiment and embodiment 2 is that the mounting part 121 of the linear reciprocating mechanism 12 is hinged to the frame 1, so that the linear reciprocating mechanism 12 is hinged to the frame 1; the second end 32 of the long hinge 3 closest to the linear reciprocating mechanism 12 is directly hinged to the output part 122 of the linear reciprocating mechanism 12, and the second connecting rod 6 is omitted.

[0106] Specifically, the spoiler pivoting drive mechanism of this embodiment includes: a linear reciprocating mechanism 12, including a mounting part 121 and an output part 122, the output part 122 being capable of linear reciprocating movement relative to the mounting part 121, the mounting part 121 being hinged to the frame 1; two or more long hinges 3, spaced apart between the output part 122 of the linear reciprocating mechanism 12 and the second end of the spoiler 2, each long hinge 3 including a first end 31, a second end 32 and a pivot point 33, the long hinge 3 being pivotally connected to the frame 1 through the pivot point 33; and a first connecting rod 5 and an intermediate connecting rod 13. The first connecting rod 5 is disposed between the second end of the spoiler 2 and the first end 31 of the long hinge 3 closest to the spoiler 2, and one end of the first connecting rod 5 is hinged to the second end of the spoiler 2, and the other end is hinged to the first end 31 of the long hinge 3 closest to the spoiler 2; an intermediate connecting rod 13 is disposed between two adjacent long hinges 3, and the two ends of the intermediate connecting rod 13 are respectively hinged to the first end 31 and the second end 32 located between the two adjacent long hinges 3; the second end 32 of the long hinge 3 closest to the linear reciprocating mechanism 12 is hinged to the output part 122 of the linear reciprocating mechanism 12.

[0107] Figure 7 The spoiler 2 is shown in the open state, and the linear reciprocating mechanism 12 is retracted. The spoiler has a large frontal area and can achieve two functions: increasing the car's grip or increasing wind resistance to reduce braking time.

[0108] Figure 8 The diagram shows the spoiler 2 in the closed state, the linear reciprocating mechanism 12 in the extended state, the spoiler parallel to the direction of the car's travel, and the frontal surface is very small, so no drag is generated in this case.

[0109] Example 4

[0110] The difference between this embodiment and embodiment 3 is that the spoiler pivot drive mechanism includes only a long hinge 3 and does not have an intermediate connecting rod 13. No schematic diagram is provided for this embodiment.

[0111] Specifically, the spoiler pivoting drive mechanism of this embodiment includes: a linear reciprocating mechanism 12, including a mounting part 121 and an output part 122, the mounting part 121 being hinged to the frame 1, and the output part 122 being capable of linear reciprocating movement relative to the mounting part 121; a long hinge 3, disposed between the output part 122 of the linear reciprocating mechanism 12 and the second end of the spoiler 2, the long hinge 3 including a first end 31, a second end 32 and a pivot point 33, the long hinge 3 being pivotally connected to the frame 1 through the pivot point 33; and a first connecting rod 5, the first connecting rod 5 being disposed between the second end of the spoiler 2 and the first end 31 of the long hinge 3, with one end of the first connecting rod 5 hinged to the second end of the spoiler 2 and the other end hinged to the first end 31 of the long hinge 3; the second end 32 of the long hinge 3 being hinged to the output part 122 of the linear reciprocating mechanism 12.

[0112] In Example 3, there are two or more long hinges 3. Unlike Example 3, this example has only one long hinge 3.

[0115] Compared to embodiment 3, this embodiment omits all the long hinges 3 and intermediate connecting rods 13.

[0116] The specific structure of the spoiler in this embodiment will be described below. The spoiler 2 may include: a spoiler body 22; and a first lug 23 protruding upward from the spoiler body 22, with both the first end and the second end of the spoiler 2 disposed on the first lug 23.
