[0002] A car spoiler is a component installed on a car. The main functions of a spoiler include reducing wind resistance and increasing downforce, thereby improving the vehicle's grip and handling. In addition, spoilers can be installed in different parts of the car, such as the rear and sides. Existing cars often have roof racks installed on the roof, which leads to loud wind noise during driving and affects the driving experience. Spoilers can also reduce drag and thus reduce wind noise.

[0003] However, existing spoilers often have a fixed angle and cannot be adapted to different car models.

[0004] Based on this, an adjustable-angle wind noise reduction spoiler is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4As shown, an adjustable-angle wind noise reduction spoiler includes a support panel 100 with multiple shark fins 200 evenly distributed on it. These shark fins guide airflow, thereby reducing wind noise. A rubber strip 300 is fixedly connected to the bottom of the support panel 100 to eliminate the gap between the support panel 100 and the roof, allowing the support panel 100 to fit more snugly against the roof. Multiple clamping components are provided on the back of the support panel 100, which clamp it onto a roof rack 400 to secure the support panel 100. Each clamping component includes a fixing block 500, one end of which is rotatably connected to... The upper clamping plate 600 is rotatably connected to the fixing block 500, thereby adjusting the angle between the support panel 100 and the roof rack 400, so that the support panel 100 can adapt to different vehicle models. A lower clamping plate 700 is rotatably connected below the upper clamping plate 600. The roof rack 400 is clamped between the upper clamping plate 600 and the lower clamping plate 700. Rotating the lower clamping plate 700 adjusts the angle between the upper clamping plate 600 and the lower clamping plate 700, thereby clamping roof racks 400 of different sizes. A reinforcing plate 800 is also provided between the fixing block 500 and the support panel 100, which can effectively improve the structural strength of the support panel 100.

[0026] In one embodiment, such as Figure 3 As shown, the support panel 100 includes a support panel body 101, shark fin mounting holes 102 and fixing block mounting holes 103. Multiple shark fin mounting holes 102 are evenly distributed on the surface of the support panel body 101, and a fixing block mounting hole 103 is also provided between two shark fin mounting holes 102.

[0027] In one embodiment, such as Figure 1 As shown, the cross-section of the edge of the support panel 100 is arc-shaped, which allows the airflow to transition more smoothly when passing through the support panel 100, thereby reducing turbulence and noise.

[0028] In one embodiment, such as Figure 3 As shown, the shark fin 200 includes a cavity 201, a fixing plate 202, a limiting mounting post 203, and a threaded mounting hole 204. The cavity 201 is provided on the inner side of the shark fin 200, which can effectively reduce the weight of the shark fin 200. Two fixing plates 202 are fixedly connected to the back of the shark fin 200. The limiting mounting post 203 that cooperates with the shark fin mounting hole 102 is fixedly connected to the fixing plate 202. The shark fin 200 is positioned and fixed by the cooperation between the shark fin mounting hole 102 and the limiting mounting post 203. The threaded mounting hole 204 is provided inside the limiting mounting post 203.

[0029] In one embodiment, such as Figure 4As shown, the fixing block 500 includes a fixing block body 501, positioning mounting holes 502, mating threaded holes 503, a first rotating shaft 504, and a positioning post 505. Two positioning mounting holes 502 that mate with the limiting mounting post 203 are provided on one side of the fixing block body 501, allowing the limiting mounting post 203 to pass through the positioning mounting holes 502 and be connected to the shark fin 200 and the fixing block 500 by screws threaded into the threaded mounting holes 204. A mating threaded hole 503 that mates with the fixing block mounting hole 103 is also provided between the two positioning mounting holes 502. The fixing block 500 is fixed to the support panel 100 by bolts passing through the holes of the fixing block mounting hole 103 and the mating threaded hole 503. A first rotating shaft 504 is also fixedly connected to the side of the fixing block body 501. A positioning post 505 is provided below the first rotating shaft 504 and is threaded into the fixing block body 501.

[0030] In one embodiment, such as Figure 4 As shown, the upper clamping plate 600 includes an arc-shaped upper clamping plate 601, a rotating mounting groove 602, a first rotating shaft mounting hole 603, an arc-shaped sliding groove 604, a second rotating shaft mounting hole 605, an upper clamping block 606, and an angle fixing mounting hole 607. One end of the arc-shaped upper clamping plate 601 has a rotating mounting groove 602, providing space for the rotation of the fixing block 500. Both sides of the rotating mounting groove 602 have first rotating shaft mounting holes 603 that mate with the first rotating shaft 504. The rotating mounting groove 602 also has holes on both sides that correspond to the shape of the positioning post 505. The matching arc-shaped slide groove 604 limits and supports the rotation of the fixed block 500; the bow-shaped upper clamping plate 601 has a through second rotating shaft mounting hole 605 on the side away from the arc-shaped slide groove 604, and the bottom of the bow-shaped upper clamping plate 601 is fixedly connected to the upper clamping block 606, which protects the roof rack 400 during the clamping process of the upper clamping plate 600; the bow-shaped upper clamping plate 601 has an angle fixing mounting hole 607 on the side away from the rotating mounting groove 602.

[0031] In this embodiment, when the support panel 100 rotates, it will drive the fixing block body 501 to rotate axially around the first rotating shaft 504. At the same time, the positioning post 505 slides synchronously along the arc-shaped slide groove 604. When the support panel 100 rotates to the position where the rubber strip 300 fits against the roof, the positioning post 505 is rotated. Since the positioning post 505 is threaded to the side of the fixing block body 501, the angle between the fixing block 500 and the upper clamping plate 600 is fixed by the positioning post 505.

[0032] In one embodiment, such as Figure 4As shown, the lower clamping plate 700 includes an arc-shaped lower clamping plate 701, a second rotating shaft 702, a lower clamping block 703, and an angle matching fixing hole 704. A lower clamping block 703 is fixedly connected to the arc-shaped lower clamping plate 701 to protect the lower end of the roof rack 400. One end of the arc-shaped lower clamping plate 701 is fixedly connected to a second rotating shaft 702 that mates with the second rotating shaft mounting hole 605. The lower clamping plate 700 is rotatably connected to the upper clamping plate 600 through the second rotating shaft 702. An angle matching fixing hole 704 that mates with the angle fixing mounting hole 607 is provided at the end of the arc-shaped lower clamping plate 701 away from the second rotating shaft 702.

[0033] In this embodiment, when clamping the roof rack 400, the lower arc-shaped clamping plate 701 is rotated around the axis of the second pivot 702, so that the lower clamping block 703 and the upper clamping block 606 respectively fit against the upper and lower end faces of the roof rack 400. Then, bolts are used to pass through the angle fixing mounting hole 607 and the angle matching fixing hole 704 to clamp the upper clamping plate 600 and the lower clamping plate 700 together.

[0034] In one embodiment, such as Figure 3 As shown, the reinforcing plate 800 includes a reinforcing plate body 801, fixing block positioning holes 802, and partitions 803. The reinforcing plate body 801 has multiple fixing block positioning holes 802 that mate with the fixing block mounting holes 103 at equal intervals. The reinforcing plate 800 is fixedly connected to the support panel 100 by bolts passing through the fixing block positioning holes 802 and the fixing block mounting holes 103. Multiple partitions 803 are fixedly connected to the top of the reinforcing plate body 801, and the position of the fixing block 500 is further fixed by two adjacent partitions 803.

[0035] Working principle: First, the upper clamping plate 600 and the lower clamping plate 700 are used to clamp the roof rack 400. The bow-shaped lower clamping plate 701 rotates around the axis of the second rotating shaft 702, so that the lower clamping block 703 and the upper clamping block 606 respectively fit against the upper and lower end faces of the roof rack 400. Next, bolts are passed through the angle fixing mounting hole 607 and the angle matching fixing hole 704 to clamp the roof rack 400 tightly with the upper clamping plate 600 and the lower clamping plate 700. Then, the support panel 100 is rotated so that the bottom of the support panel 100... The rubber strip 300 fits against the roof. During the rotation of the support panel 100, it will drive the fixing block body 501 to rotate axially around the first rotating shaft 504, which will adjust the angle of the spoiler. At the same time, the positioning post 505 slides synchronously along the arc-shaped slide groove 604. When the fixing block 500 rotates to the appropriate position, the positioning post 505 is rotated. Since the positioning post 505 is threaded to the side of the fixing block body 501, the angle between the fixing block 500 and the upper clamping plate 600 is fixed by the positioning post 505.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
