Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and in particular to a front bumper air duct and a vehicle. Background Art

[0002] The vehicle's overall lift coefficient is an important factor affecting the vehicle's handling performance. Aerodynamic devices such as rear wings change the flow field distribution around the vehicle, thereby generating corresponding forces to reduce the vehicle's overall lift coefficient, that is, increase the vehicle's downforce and improve the vehicle's handling performance.

[0003] When the downforce of the vehicle increases, the resistance will increase, thus affecting the acceleration performance, maximum speed, fuel consumption, and cruising range of the vehicle. In certain operating conditions, the adjustment of resistance is equally important, so the DRS (Drag Reduction System) system is created to actively adjust the downforce and resistance of the vehicle. For example, when the vehicle is in a braking or turning condition, the vehicle needs more downforce to improve the vehicle's grip performance, then the DRS system is turned off, and the vehicle is in a high downforce state. Although the resistance is also greater, it hardly affects the vehicle performance in the current scene; when the vehicle is accelerating or driving at high speed, the vehicle needs lower vehicle resistance, then the DRS system is turned on, and the resistance of the vehicle is greatly reduced. Although the lift of the vehicle is also reduced accordingly, the vehicle is not particularly sensitive to grip performance at this time.

[0004] At present, there are relatively mature solutions for controlling the lift of the rear axle of the vehicle, such as the DRS tail wing system, which can adjust the lift of the rear axle of the vehicle and thus improve the vehicle's handling performance. However, the solutions in the related art cannot adjust the lift of the front axle of the vehicle. Therefore, it is urgent to provide a solution that can adjust the lift of the front axle of the vehicle to further improve the vehicle's handling performance. Utility Model Content

[0005] The present disclosure provides a front bumper air duct to adjust the lift of the front axle of a vehicle and improve the handling performance of the vehicle.

[0006] The front bumper air duct of the present invention includes an air duct body and a movable plate, wherein the air duct body surrounds the air duct; at least a portion of the movable plate is arranged in the air duct body, and the movable plate is rotatably connected to the air duct body to switch between a first position closing the air duct and a second position opening the air duct.

[0007] Optionally, a first stopper is provided in the air duct body, and the movable plate stops against the first stopper when being in the first position.

[0008] Optionally, the first stopper is a first stopper, and the movable plate is in contact with the first stopper when in the first position.

[0009] Optionally, there are multiple first stoppers, some of which are arranged on the top wall of the air duct, and another part of which are arranged on the bottom wall of the air duct.

[0010] Optionally, the movable panel includes a first part and a second part, the first part is arranged in the air duct body, the first part is used to open and close the air duct, and the second part is arranged outside the air duct body and is located on the bottom wall of the air duct body; when the movable panel is in the first position, the second part blocks the front lower side of the front wheel of the vehicle; when the movable panel is in the second position, the front lower side of the front wheel of the vehicle is exposed.

[0011] Optionally, a second stopper is disposed outside the air duct body, and when the movable plate is in the first position, the second part stops at the second stopper.

[0012] Optionally, the second stopping member is a second baffle plate, and when the movable plate is in the second position, the second part is in contact with the second stopping member.

[0013] Optionally, the shape of the movable plate is consistent with the shape of the bottom wall of the air duct, and the movable plate is in contact with the bottom wall of the air duct when in the second position.

[0014] The vehicle disclosed herein comprises the front bumper air duct described in any one of the above items.

[0015] Optionally, the vehicle includes a front wheel, and the movable panel is integrally arranged on the front side of the front wheel.

[0016] The front bumper air duct disclosed in the present invention is provided with a movable plate rotatably connected to the air duct body, so that when the movable plate is rotated to the first position, the air duct is closed; when the movable plate is rotated to the second position, the air duct is opened. When the air duct is closed, the airflow cannot enter from the air duct, which can reduce the air duct resistance and put the whole vehicle in a low resistance state. When the air duct is opened, the airflow flows through the air duct, and the airflow flowing through the air duct generates downward downforce, which improves the grip performance of the front wheels of the vehicle. When the downforce increases, the resistance of the whole vehicle will also increase. Therefore, by rotating the movable plate, the lift of the front axle of the vehicle can be adjusted to improve the handling performance of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0035] like Figures 1 to 6 As shown, the front bumper air duct of the embodiment of the present disclosure includes an air duct body 1 and a movable plate 2, the air duct body 1 encloses an air duct 11, and at least a portion of the movable plate 2 is disposed in the air duct body 1. The movable plate 2 is rotatably connected to the air duct body 1 to switch between a first position closing the air duct 11 and a second position opening the air duct 11.

[0036] The front bumper air duct of the disclosed embodiment is provided with a movable plate 2 rotatably connected to the air duct body 1, so that when the movable plate 2 rotates to the first position, the air duct 11 is closed; when the movable plate 2 rotates to the second position, the air duct 11 is opened. Figure 3 As shown, when the air duct 11 is closed, the airflow cannot enter from the air duct 11, which can reduce the air duct resistance and put the whole vehicle in a low resistance state. Figure 6 As shown, when the air duct 11 is opened, air flows through the air duct 11 , and the air flow flowing through the air duct 11 generates downward downforce, thereby improving the grip performance of the front wheels 6 of the vehicle, and also generates additional resistance.

[0037] Thus, the lift of the front axle of the vehicle can be adjusted by rotating the movable plate 2, thereby improving the vehicle handling performance. For example, when the vehicle is in a braking or turning condition, the movable plate 2 is rotated so that the movable plate 2 is in the first position; when the vehicle is in an acceleration or high-speed driving condition, the movable plate 2 is rotated so that the movable plate 2 is in the second position.

[0038] In some embodiments, Figure 2 and Figure 5 As shown, a first stopper 3 is disposed in the air duct body 1 , and the movable plate 2 stops against the first stopper 3 when being in the first position.

[0039] By providing the first stopper 3 and abutting against the first stopper 3 when the movable panel 2 is in the first position, the first stopper 3 can be used to limit the rotation angle of the movable panel 2 so that the movable panel 2 is in the first position, thereby improving the reliability of the front bumper air duct.

[0040] Optionally, the first stopper 3 is a first stopper plate, and the movable plate 2 is in contact with the first stopper 3 when in the first position.

[0041] By setting the first stopper 3 as the first baffle and fitting with the first stopper 3 when the movable panel 2 is in the first position, when the movable panel 2 is in the first position, the contact area between the movable panel 2 and the first stopper 3 is larger, thereby reducing the risk of leakage of airflow through the movable panel 2 and the first stopper 3, achieving the effect of reliable closure of the air duct 11, and further improving the reliability of the front bumper air duct.

[0042] Of course, in other embodiments, the first stopper 3 may also be in a block shape. For example, a first convex block is provided in the air duct 11 , and the first convex block forms the first stopper 3 .

[0043] Optionally, the first stopper 3 is formed integrally with the air duct body 1. In other words, the first stopper 3 and the air duct body 1 are an integrated structure.

[0044] Of course, in other embodiments, the first stopper 3 and the air duct body 1 may also be welded, bonded, or connected via fasteners, wherein the fasteners may be bolts, screws, rivets, and the like.

[0045] Alternatively, if Figure 2 and Figure 5 As shown, there are multiple first stoppers 3 , wherein a portion of the first stoppers 3 are disposed on the top wall of the air duct 11 , and another portion of the first stoppers 3 are disposed on the bottom wall of the air duct 11 .

[0046] For example, there are two first stoppers 3, one of which is disposed on the top wall of the air duct 11, and the other is disposed on the bottom wall of the air duct 11. The movable plate 2 stops against the two first stoppers 3 when in the first position.

[0047] By providing a plurality of first stops 3, when the movable panel 2 is in the first position, on the one hand, the first stops 3 can be utilized to more reliably limit the rotation angle of the movable panel 2, thereby further improving the reliability of the front bumper air duct; on the other hand, the contact area between the movable panel 2 and the first stops 3 is larger, thereby further improving the reliability of the front bumper air duct.

[0048] In order to make the technical solution of the present disclosure easier to understand, the technical solution of the present disclosure is further described below by taking the height direction of the air duct 11 as being consistent with the up-down direction. Figures 1 to 6 shown.

[0049] The top wall of the air duct 11 is arranged on the upper side of the bottom wall of the air duct 11, and the two first stoppers 3 are arranged at intervals in the vertical direction. The movable plate 2 has two first stop portions, and when the movable plate 2 is in the first position, the two first stop portions stop against the two first stoppers 3 respectively.

[0050] In some embodiments, the movable panel 2 includes a first portion 21 and a second portion 22. The first portion 21 is disposed inside the air duct body 1 and is used to open and close the air duct 11. The second portion 22 is disposed outside the air duct body 1 and is located on the bottom wall of the air duct body 1. When the movable panel 2 is in the first position, the second portion 22 blocks the front lower side of the front wheel 6. When the movable panel 2 is in the second position, the front lower side of the front wheel 6 is exposed. Figures 1 to 6 shown.

[0051] It should be noted that, when the movable panel 2 is in the first position, there should be a certain distance between the bottom end of the movable panel 2 and the ground 10 to prevent the movable panel 2 from interfering with the ground 10 .

[0052] When the movable panel 2 is in the first position, the second part 22 is used to block the front lower side of the front wheel 6, so that the second part 22 acts as a wind blocker for the front wheel, so that the airflow passing through the second part 22 can flow from both sides and the lower part of the second part 22, reducing the impact on the front wheel 6, thereby achieving the effect of reducing resistance and further reducing the resistance of the whole vehicle. When the movable panel 2 is in the second position, the front lower side of the front wheel 6 is exposed, so that the airflow flowing from the lower side of the air duct body 1 can impact the front wheel 6, increasing the resistance of the front wheel 6.

[0053] Optionally, a second stopper 4 is disposed outside the air duct body 1 , and when the movable plate 2 is in the first position, the second portion 22 stops against the second stopper 4 .

[0054] By providing the second stopper 4, and when the movable panel 2 is in the first position, the second portion 22 stops against the second stopper 4, and the second stopper 4 can be used to limit the rotation angle of the movable panel 2 so that the movable panel 2 is in the first position, thereby improving the reliability of the front bumper air duct.

[0055] Optionally, the second stopping member 4 is a second stop plate, and when the movable plate 2 is in the second position, the second portion 22 fits against the second stopping member 4 .

[0056] By setting the second stopper 4 as the second baffle, and when the movable panel 2 is in the first position, the second part 22 is in contact with the second stopper 4, so that when the movable panel 2 is in the first position, the contact area between the movable panel 2 and the second stopper 4 is larger, thereby reducing the risk of leakage of airflow through the movable panel 2 and the second stopper 4, achieving the effect of reliable closure of the air duct 11, and further improving the reliability of the front bumper air duct.

[0057] Of course, in other embodiments, the second stopper 4 may also be in a block shape. For example, a second convex block is provided in the air duct 11 , and the second convex block forms the second stopper 4 .

[0058] Optionally, the second stopper 4 is formed integrally with the air duct body 1. In other words, the second stopper 4 and the air duct body 1 are an integral structure.

[0059] Of course, in other embodiments, the second stopper 4 and the air duct body 1 may also be welded, bonded or connected via fasteners, wherein the fasteners may be bolts, screws, rivets and the like.

[0060] In some embodiments, Figure 2 and Figure 5 As shown, the front bumper air duct further includes a rotating shaft 5 , the movable plate 2 is connected to the rotating shaft 5 , and the rotating shaft 5 is rotatable relative to the air duct body 1 .

[0061] For example, the air duct body 1 has a rotating shaft hole, the rotating shaft 5 is rotatably disposed in the rotating shaft hole, and the rotating shaft 5 is rotatably connected to the front bumper 7 .

[0062] By providing the rotating shaft 5 , the rotation connection between the movable plate 2 and the air duct body 1 can be easily achieved.

[0063] In some embodiments, the shape of the movable plate 2 is consistent with the shape of the bottom wall of the air duct 11 , and the movable plate 2 fits with the bottom wall of the air duct 11 when it is in the second position.

[0064] For example, the bottom wall of the air duct 11 is arc-shaped, and the movable plate 2 is also an arc-shaped plate, so that the movable plate 2 can fit with the bottom wall of the air duct 11 when it is in the second position. Specifically, the first part 21 fits with the inner side of the bottom wall of the air duct 11, and the second part 22 fits with the outer side of the bottom wall of the air duct 11.

[0065] By setting the movable plate 2 to be in contact with the bottom wall of the air duct 11 when in the second position, it is possible to more effectively avoid the movable plate 2 from blocking the air duct 11 and the front wheel 6, thereby increasing the amount of airflow passing through the air duct 11 and the front wheel 6, which is beneficial to increasing the resistance of the entire vehicle and improving the grip performance of the front wheel 6.

[0066] The vehicle of the disclosed embodiment includes the front bumper air duct of any one of the above embodiments.

[0067] Therefore, the vehicle of the embodiment of the present disclosure has advantages such as good handling performance.

[0068] like Figure 1 and Figure 4 As shown, the vehicle includes a front bumper 7, a front fender 8 and a front lip 9, and the two ends of the air duct 11 are respectively an air duct inlet 12 and an air duct outlet 13. The air duct inlet 12 is arranged on the left and right sides of the front bumper 7 and located at the rear side of the front lip 9; the air duct outlet is arranged in the front fender 8 area.

[0069] like Figure 3 As shown, when the movable plate 2 is in the first position, the first part 21 acts as a valve, blocking the air duct 11, so that the airflow cannot enter from the air duct 11, reducing the air duct resistance; the second part 22 acts as a front wheel wind blocker, and after the airflow passes through the second part 22, it flows from the left and right sides and the bottom of the second part 22 to avoid directly flowing to the front wheel 6 of the vehicle, reducing the impact on the front wheel 6 of the vehicle, and achieving the effect of reducing the resistance of the front wheel 6. In this state, the vehicle is in a low resistance and low downforce state, which is mainly used in vehicle acceleration and high-speed driving conditions.

[0070] like Figure 6As shown, when the movable panel 2 is in the second position, the airflow above the front lip 9 enters the air duct 11 from the air duct inlet 12 and flows out from the front fender 8, thereby generating downward downforce. The airflow below the front lip 9 is accelerated to flow upward under the guidance of the lower body of the air duct 11 and the ground, and can also generate a certain downforce component. The generation of downforce will also be accompanied by an increase in resistance, and the air duct 11 itself will bring additional resistance. In addition, the airflow on the lower surface of the front lip 9 will impact the front wheel 6 after flowing upward, increasing the resistance of the front wheel 6. In this state, the vehicle is in a high downforce and high resistance state, which can be used for vehicle braking and turning conditions. In this condition, more downforce is required to keep the vehicle with better grip, and there is no great demand for resistance.

[0071] Optionally, the movable panel 2 is disposed as a whole on the front side of the front wheel 6. That is to say, the movable panel 2 is located as a whole on the front side of the front wheel 6 of the vehicle regardless of whether it is in the first position or the second position.

[0072] By arranging the movable panel 2 as a whole in front of the front wheel 6, on the one hand, when the movable panel 2 is in the first position, the second portion 22 can more effectively shield the front lower side of the front wheel 6, thereby more effectively reducing the resistance of the entire vehicle; on the other hand, it can effectively avoid interference between the movable panel 2 and the front wheel 6 during movement, thereby improving the reliability of the vehicle.

[0073] The vehicle of the embodiment of the present disclosure can adjust the state of the movable panel 2 by the following method:

[0074] In the initial state, the movable plate 2 is in the first position;

[0075] When the brake pedal is stepped on, the movable plate 2 is adjusted to switch to the first position. At this time, the first part 21 of the movable plate 2 abuts against the first stopper 3, and the second part 22 of the movable plate 2 abuts against the second stopper 4;

[0076] When the brake pedal is released and the wheel turns more than 5 degrees, the movable plate 2 is adjusted to switch to the second position;

[0077] When the brake pedal is released and the wheel turns less than 5 degrees, the movable plate 2 is adjusted to switch to the first position.

[0078] The vehicle of the disclosed embodiment disposes a movable panel 2 in the air duct 11 of the front bumper air duct and adjusts the movable panel 2 to different positions so that the vehicle can be in a high downforce state and a low resistance state respectively to cope with different operating conditions and maximize the performance of the vehicle.

[0079] Although the embodiments of the present disclosure have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present disclosure. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present disclosure.
