Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts and components, in particular to an adjustable front bumper drag reduction device. Background Art

[0002] Wind resistance has a direct impact on fuel consumption during driving. Reducing wind resistance helps keep the car running smoothly and reduce fuel consumption. Designs designed to reduce the air resistance of vehicles when driving at high speeds. Air resistance, also known as wind resistance, is one of the main resistances encountered by cars during driving. It increases fuel consumption and reduces vehicle performance. By optimizing the aerodynamic characteristics of the vehicle, fuel efficiency can be significantly improved and emissions can be reduced.

[0003] In the prior art, a deflector or a front lip is added to the front bumper to improve the air flow characteristics of the vehicle, thereby reducing wind resistance and improving vehicle stability. When the vehicle is driving at high speed, a lift force will be generated due to the pressure difference. When the speed reaches a certain value, the lift force will overcome the weight of the vehicle and lift the vehicle upward, reducing the adhesion between the wheels and the ground, causing the vehicle body to float and resulting in poor driving stability.

[0004] However, existing deflectors or front lips are usually fixedly installed with a fixed angle, which is not conducive to adjustment according to vehicle speed and driving environment. When the angle of the front lip increases, it is easy to affect the height of the chassis of the vehicle body, which is not conducive to the vehicle driving on some roads. When the angle of the front lip is small, the downforce is low, which is not conducive to improving the stability of the vehicle when driving at high speeds and is not conducive to achieving the purpose of optimizing air flow. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model adopts an adjustable front lip drag reduction structure in the form of an active connection.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, the utility model provides an adjustable front bumper drag reduction device, including a bar body assembly 10, a front lip 20 is arranged on the bar body assembly 10, an adjusting member 21 is arranged on one side of the front lip 20, and a movable baffle 11 is arranged on the bar body assembly 10 for movably abutting against the front lip 20, the front lip 20 rotates around the connection between it and the adjusting member 21 to form an angle adjustment structure, and the front lip 20 drives the movable baffle 11 to translate in the vertical direction of the bar body assembly 10 to form a closed structure.

[0025] The utility model adopts an adjustable front lip drag reduction structure in the form of an active connection. During driving, the downforce is increased by adjusting the angle of the front lip to guide the airflow through the bottom of the vehicle, thereby improving the stability of the vehicle when driving at high speeds, and facilitating adaptive adjustment according to the vehicle's driving speed and environment, thereby achieving the purpose of adjusting the drag coefficient to reduce wind resistance. Cooperating with the active baffle is conducive to reducing the gap generated during the front lip adjustment process, thereby reducing the situation where the airflow enters the front of the vehicle and increases the resistance.

[0026] The front lip 20 is driven to rotate and adjust the angle through the adjusting member 21, which is beneficial to adjust the inclination angle of the front lip 20 and thus adjust the downforce during the driving of the vehicle, guide the airflow to reduce wind resistance, and drive the movable baffle 11 to move vertically during the adjustment of the front lip 20, which is beneficial to block the gap between the front lip 20 and the bar assembly 10 through the movable baffle 11, thereby reducing excessive airflow entering and causing increased resistance.

[0027] By adjusting the front lip 20° angle according to vehicle speed, wind resistance can be reduced through airflow guidance, downforce regulation, gap optimization and drag coefficient adjustment.

[0028] like Figure 2 and Figure 4 As shown, the front lip 20 is arranged obliquely, and a connecting rod 22 is movably mounted on the front lip 20 via a rotating shaft, and the movable end of the connecting rod 22 is connected to the movable baffle 11 via the rotating shaft.

[0029] The front lip 20 is rotatably connected to the movable baffle 11 through the connecting rod 22, so that when the front lip 20 is rotated and tilted, the movable baffle 11 is driven downward by the connecting rod 22, which can block the gap between the front lip 20 and the bar assembly 10 when the front lip 20 rotates, reduce the formation of vortices in the gap, thereby reducing the air flow entering the front end of the vehicle, which is beneficial to maintaining the stability of the vehicle's driving and reducing the impact of air flow on resistance.

[0030] like Figure 3 As shown, the movable baffle 11 includes a silicone strip 12 arranged on the lower surface thereof, and a slider 13 is arranged on one side of the movable baffle 11. The movable baffle 11 is slidably connected to the lever body assembly 10 via the slider 13.

[0031] The movable baffle 11 slides and translates on one side of the lever assembly 10 through the slider 13, which helps to keep the movable baffle 11 moving vertically when the front lip 20 rotates and tilts, so that the bottom end of the movable baffle 11 always abuts against the movable baffle 11;

[0032] At the same time, the movable baffle 11 and the front lip 20 are connected by the silicone strip 12, which is beneficial to play a buffering role at the connection, can reduce the friction and wear between the front lip 20 and the movable baffle 11 during rotation, and is beneficial to reduce the noise and increased resistance during rotation.

[0033] like Figure 3 and Figure 4 As shown, the adjustment member 21 includes a shaft 211, a gear 212 and a rack 213, the shaft 211 passes through the inner wall of the gear 212 and one side of the front lip 20 and extends to one side of the lever assembly 10, and the gear 212 is meshedly connected with the rack 213.

[0034] The front lip 20 and the bumper assembly 10 are connected via the adjusting member 21, and the rack 213 is controlled to translate by installing an external driving mechanism, thereby driving the gear 212 to rotate, and further rotating the front lip 20 to adjust the tilt angle. The external driving mechanism is connected via the rack 213, which facilitates the installation of the driving mechanism at a location outside the bumper, such as on the vehicle frame, thereby reducing the weight of the bumper and alleviating pressure.

[0035] By optimizing the 20° angle of the front lip, the vehicle's drag coefficient can be adjusted, reducing the drag coefficient and reducing wind resistance.

[0036] like Figure 2 and Figure 3As shown, a silicone baffle 23 is fixedly provided on the front lip 20 , an insert 24 movably abutting against the lever body assembly 10 is fixedly provided at one end of the silicone baffle 23 , and a slot 14 matching the insert 24 is provided on the lower surface of the lever body assembly 10 .

[0037] A limit plate 25 is fixedly installed on one side of the lower surface of the lever body assembly 10 near the silicone spoiler 23. The limit plate 25 is used to limit the bending direction and angle of the silicone spoiler 23, and can be adjusted together during the adjustment process of the front lip 20. The silicone spoiler 23 is used to flexibly connect the front lip 20 and the lever body assembly 10, reduce the gap between the lever body assembly 10 and the front lip 20, and play a buffering role during the rotation of the front lip 20, which is further helpful to prevent airflow and impurities from entering the gap between the front lip 20 and the lever body assembly 10.

[0038] At the same time, it is beneficial to enhance the separation effect of the movable baffle 11, optimize the gap, reduce the formation of air vortices, and guide the airflow to flow more smoothly, thereby achieving the purpose of reducing wind resistance.

[0039] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
