[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-5 An adjustable car fairing 1 is shown. The fairing 1 is hollow inside. The front end of the fairing 1 extends downward in an arc shape and the rear end is provided with a baffle 2. The bottom end of the fairing 1 is provided with a base plate 3 fixed to the vehicle. A movable adjusting member 4 is provided above the base plate 3. The adjusting member 4 extends upward and is provided with a connecting member 5 at the top. The fairing 1 is connected to the adjusting member 4 through the connecting member 5. A telescopic mechanism 6 is installed on the outer wall of the baffle 2 facing the inner side of the fairing 1. The output end of the telescopic mechanism 6 is connected to the adjusting member 4. The telescopic mechanism 6 drives the adjusting member 4 to move, so that the fairing 1 moves horizontally on the base plate 3. The operation of the adjusting member 4 drives the fairing 1 to move up and down.

[0022] Based on the above, the telescopic mechanism 6 drives the adjusting component 4 to move horizontally, thereby adjusting the lateral position of the guide shield 1; the second servo push rod 41 in the adjusting component 4 drives the guide shield 1 to rise and fall vertically, forming a two-dimensional adjustment system.

[0023] The curved front design guides airflow, the hollow structure reduces weight, and the base plate 3 ensures installation stability.

[0024] The horizontal and vertical adjustments adapt to the roof contours of different car models, optimize the aerodynamic layout, reduce wind resistance with the curved front end, and balance strength and lightweight with the hollow structure.

[0025] The telescopic mechanism 6 includes a first servo push rod 61 fixedly installed on the baffle 2. A positioning frame 62 is sleeved on the outside of the first servo push rod 61. The positioning frame 62 is fixed on the surface of the base plate 3. The output shaft of the first servo push rod 61 extends toward the guide shroud 1. A chassis 63 is installed at the end of the output shaft of the first servo push rod 61. The adjusting member 4 is installed on the surface of the chassis 63.

[0026] Based on the above, the first servo push rod 61 is fixed to the baffle 2, and pushes the chassis 63 to slide along the positioning frame 62 through the output shaft, thereby driving the adjusting component 4 and the fairing 1 to move horizontally; the positioning frame 62 restricts the radial displacement of the push rod to ensure the accurate thrust direction. The positioning frame 62 fixes the first servo push rod 61 to ensure the straightness of the lateral movement of the fairing 1. The thrust of the servo push rod is controllable and adapts to the aerodynamic load during high-speed driving.

[0027] The bottom of the chassis 63 is provided with a limiting strip 631 parallel to the direction of movement of the guide shroud 1, and a first limiting groove plate 632 is fixedly installed on the bottom plate 3, which is sleeved on the outside of the limiting strip 631.

[0028] Based on the above, the limiting strip 631 is embedded in the first limiting groove plate 632 to form a sliding pair guide structure, which restricts the offset when the chassis 63 moves horizontally, and ensures that the fairing 1 moves along the preset trajectory. The gap between the limiting strip 631 and the groove plate is small, which prevents the fairing 1 from swaying laterally due to road bumps and has strong anti-offset capability.

[0029] The adjusting component 4 includes a second servo push rod 41 fixedly installed on the surface of the chassis 63. Several limiting sleeves 42 are provided on both sides of the second servo push rod 41, and a movable limiting rod 43 is inserted into the limiting sleeve 42.

[0030] Based on the above, the second servo push rod 41 vertically extends and retracts to drive the flow guide 1 to rise and fall. The limiting sleeve 42 and the limiting rod 43 cooperate to limit the radial swing of the push rod, ensuring that the rising and falling process is smooth and without tilting. The guiding effect of the limiting rod 43 and the sleeve reduces the verticality error of the rising and falling, avoiding the aerodynamic performance degradation caused by the tilting of the flow guide 1.

[0031] The connecting component 5 includes a connecting plate 51 fixed to the top of the output shaft of the second servo push rod 41 and a fastening bolt 52 inserted into the flow guide 1. The fastening bolt 52 passes through the flow guide 1 and the connecting plate 51 and extends to the bottom of the connecting plate 51. A first nut 53 and a second nut 54 are sleeved on the outside of the fastening bolt 52.

[0032] The first nut 53 is fixed on the inner wall of the flow guide 1 and located above the connecting plate 51, and the second nut 54 is fixed on the bottom wall of the connecting plate 51.

[0033] Based on the above, the fastening bolt 52 passes through the guide shield 1 and the connecting plate 51, and is locked by double nuts to form a rigid connection, ensuring that the guide shield 1 is fixed in position after adjustment. The double nut anti-loosening design avoids bolt loosening caused by high-speed vibration, and the connection has high reliability.

[0034] A distance sensor 7 is also installed on the outer wall of the baffle 2 facing the guide shroud 1, which is used to detect the distance and position of the guide shroud 1 movement and prevent its displacement from being excessive.

[0035] Two sets of limiting plates 8 are fixedly installed on the inner wall of the flow guide shroud 1 located on both sides of the adjusting component 4. A second limiting groove plate 9 that cooperates with the limiting plate 8 is fixedly installed on the bottom plate 3. The limiting plate 8 is inserted into the inside of the second limiting groove plate 9.

[0036] The gap between the front and rear sets of limiting plates 8 is greater than the length of the second limiting groove plate 9;

[0037] The limiting plate 8 is inserted into the second limiting groove plate 9 to form a longitudinal limit, allowing the guide shield 1 to move horizontally while restricting its forward and backward displacement; the gap design provides room for the vertical movement of the guide shield 1. When the guide shield 1 is raised or lowered, the limiting plate 8 is raised or lowered at the gap without conflicting with the second limiting groove plate 9.

[0038] Based on the above, when it is necessary to disassemble the fairing 1, the first servo push rod 61 pushes the fairing 1 away from the top of the roof, avoiding interference from components such as the sunroof and luggage rack, so that the fastening bolts 52 of the connecting part 5 are fully exposed, making it easy to operate with tools such as wrenches.

[0039] The raised fairing 1 and the base plate 3 form an operating gap, allowing staff to reach into the gap by hand to remove the bottom bolts, avoiding the inconvenience of having to bend over or use special tools as required by the traditional fixed fairing 1.

[0040] After horizontal movement, the fastening bolts 52 of the connecting part 5 are moved from the shaded area of ​​the roof to the side of the vehicle body, where there is ample light and open space. After horizontal movement, the fairing 1 is moved to the outside of the vehicle body, and the dust, insect residue, etc. on the inner side of the arc-shaped front end can be wiped directly with a cloth without disassembling the entire part.

[0041] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
