[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0043] The wind resistance device 100 for a vehicle of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. The wind resistance device 100 is used to improve the braking performance of the vehicle to shorten the braking distance of the vehicle, further improve the braking effect of the vehicle, and reduce the risk of traffic accidents.

[0044] The wind resistance device 100 for a vehicle according to an embodiment of the present application includes: a mounting bracket 1 , a wind resistance plate 2 , a driving assembly 3 and a connecting rod assembly 4 .

[0045] Among them, the mounting bracket 1 is arranged on the top of the vehicle body, and the wind resistance plate 2 is connected to the mounting bracket 1 in a flippable manner around a first axis, and the wind resistance plate 2 can be arranged opposite to the traveling direction of the vehicle to increase the wind resistance of the vehicle in the traveling direction through the wind resistance plate 2, thereby shortening the braking distance of the vehicle.

[0046] It should be noted that the wind resistance plate 2 is arranged opposite to the traveling direction of the vehicle, so that the airflow opposite to the traveling direction generated during the vehicle's travel can act on the wind resistance plate 2, thereby increasing the wind resistance of the entire vehicle through the wind resistance plate 2. Preferably, the windshield surface of the wind resistance plate 2 is arranged opposite to the X direction of the vehicle.

[0047] At the same time, the driving component 3 is installed on the mounting bracket 1, the connecting rod assembly 4 is connected between the driving component 3 and the wind resistance plate 2, and the driving component 3 is used to drive the connecting rod 43 component to drive the wind resistance plate 2 to rotate relative to the mounting bracket 1, so that when it is necessary to improve the braking performance of the vehicle through the wind resistance device 100, the driving component 3 drives the connecting rod 43 component to drive the wind resistance plate 2 to flip and open relative to the mounting bracket 1, thereby opening the wind resistance plate 2 and shortening the braking distance of the vehicle by increasing the wind resistance of the vehicle.

[0048] It should be noted that the mounting bracket 1 is a mounting carrier for the wind deflector 2, the driving assembly 3 and the connecting rod assembly 4. The mounting bracket 1 can be constructed as a bracket structure independent of the vehicle body, and further assembled to the top of the vehicle body; the mounting bracket 1 can also be constructed as a part of the vehicle body, such as the top wall of the vehicle body, so as to mount the wind deflector 2, the driving assembly 3 and the connecting rod assembly 4 on the top wall of the vehicle body.

[0049] The wind resistance device 100 is used to improve the braking performance of the vehicle so as to increase the forward wind resistance of the vehicle when the vehicle brakes, thereby assisting braking and shortening the braking stroke of the vehicle.

[0050] Reference Figure 1 and Figure 5 It can be seen that the wind resistance device 100 includes at least two working states, namely, an open state and a closed state, so that the wind resistance device 100 can be selectively opened according to the braking requirements of the vehicle. Figure 1 As shown, when the wind resistance device 100 is in the closed state, the wind resistance plate 2 fits with the top surface of the mounting bracket 1, thereby reducing the resistance generated at the wind resistance plate 2 and ensuring the normal operation of the vehicle; Figure 5 As shown, when the wind resistance device 100 is in the open state, the wind resistance plate 2 is flipped and opened at a certain angle relative to the mounting bracket 1, and at least part of the wind resistance plate 2 can be arranged relative to the traveling direction of the vehicle, thereby increasing the resistance generated at the wind resistance plate 2, increasing the forward resistance of the vehicle, and thus shortening the braking stroke of the vehicle.

[0051] At present, vehicles use friction braking to achieve vehicle braking. If an emergency occurs while the vehicle is moving, even if the driver brakes in time, due to the limitations of the vehicle's own braking performance, there is still a problem of long braking distance, which still poses a safety hazard.

[0052] In the present application, the wind resistance device 100 can be opened by setting the wind resistance plate 2 relative to the direction of travel of the vehicle, thereby improving the braking performance of the vehicle by increasing the wind resistance of the vehicle and shortening the braking distance of the vehicle. It can be understood that the greater the resistance of the vehicle during travel, the shorter the braking distance required for the vehicle to brake, so when the vehicle needs to brake, the wind resistance device 100 is opened to increase the wind resistance of the whole vehicle, which can effectively shorten the braking distance required for the vehicle. At the same time, when the vehicle travels faster, the braking effect of the vehicle is improved by increasing the wind resistance, which can shorten the braking distance of the vehicle.

[0053] like Figure 7As shown, in some embodiments of the present application, the wind resistance device 100 further includes a hinge 6, and the hinge 6 is connected between the mounting bracket 1 and the wind resistance plate 2, so as to realize that the wind resistance plate 2 is rotatably connected to the mounting bracket 1. It should be noted that the connection method between the wind resistance plate 2 and the mounting bracket 1 is not limited to this, and can also be a connection shaft and a shaft seat, such as: forming a shaft seat on the mounting bracket 1, forming a connection shaft on the wind resistance plate 2, and realizing that the wind resistance plate 2 is rotatably mounted on the mounting bracket 1 through the connection shaft and the shaft seat.

[0054] like Figure 3 and Figure 7 As shown, in some embodiments of the present application, the driving assembly 3 includes: a driving motor 31 and a driving sleeve 32, the driving motor 31 is provided with a driving shaft 311 rotating around a second axis, the driving sleeve 32 is sleeved on the driving shaft 311 and is dynamically connected to the driving shaft 311, and the driving sleeve 32 is connected to the connecting rod assembly 4.

[0055] Combination Figure 3 and Figure 7 Driven by the driving shaft 311, the driving sleeve 32 can move relative to the driving motor 31 along the axial direction of the second axis, and the driving sleeve 32 can drive the connecting rod assembly 4 to move during the movement, thereby further driving the wind resistance plate 2 to rotate relative to the mounting bracket 1 through the connecting rod assembly 4, and adjusting the opening angle of the wind resistance plate 2 relative to the mounting bracket 1.

[0056] Since the drive sleeve 32 is connected to the connecting rod assembly 4, the connecting rod assembly 4 can limit the rotation of the drive sleeve 32, so that the drive sleeve 32 can be driven by the drive shaft 311 to move in the axial direction of the second axis. The driving method has high reliability and stable power output, which can ensure the driving effect at the wind resistance plate 2.

[0057] It can be understood that the resistance generated by the wind resistance device 100 on the top of the vehicle is related to the opening angle of the wind resistance plate 2. By controlling the opening angle of the wind resistance plate 2, the resistance generated at the wind resistance device 100 can be adjusted so that the wind resistance plate 2 can be driven to a corresponding opening angle according to the braking requirements of the vehicle.

[0058] Among them, when the driving speed of the vehicle is the same, the greater the resistance generated at the wind resistance plate 2, the shorter the braking distance required by the vehicle. Therefore, the wind resistance can be adjusted by adjusting the opening angle of the wind resistance plate 2 relative to the mounting bracket 1, so as to control the wind resistance plate 2 to open to the corresponding opening angle according to the braking distance required by the vehicle.

[0059] like Fig.12As shown, in a further embodiment of the present application, the drive assembly 3 also includes a drive guide rail 33, which is fixed to the drive motor 31, and the drive guide rail 33 is used to guide and cooperate with the drive sleeve 32 to improve the stability of the drive sleeve 32 during movement and ensure the driving effect of the drive sleeve 32 on the connecting rod assembly 4.

[0060] The driving guide rail 33 can be fixed to the driving motor 31 directly or indirectly, such as: the driving guide rail 33 is fixed to the housing of the driving motor 31, the driving guide rail 33 is fixed relative to the driving motor 31 by being connected to the mounting bracket 1, etc.

[0061] Furthermore, the driving guide rail 33 is formed with a guide groove 333 extending in the axial direction of the second axis, the sleeve is arranged in the guide groove 333, and the inner wall of the guide groove 333 can fit with the driving sleeve 32 to further improve the movement stability of the driving sleeve 32.

[0062] Reference Fig.12 The driving guide rail 33 includes a first guide rail 331 and a second guide rail 332, which are opposite to each other and spaced apart. The first guide rail 331 and the second guide rail 332 are respectively arranged on both sides of the driving shaft sleeve 32 to form a guide rail while avoiding the connecting rod assembly 4 to prevent interference between the driving guide rail 33 and the connecting rod assembly 4.

[0063] like Fig.11 As shown, in some embodiments of the present application, the connecting rod assembly 4 includes: a driving connecting rod 43 , a first mounting seat 41 and a second mounting seat 42 .

[0064] Further integration Figure 5 The first mounting seat 41 is arranged on the wind deflector plate 2 to form a connection structure on the wind deflector plate 2, and the second mounting seat 42 is arranged on the driving sleeve 32 to form a connection structure on the driving sleeve 32. One end of the driving connecting rod 43 is rotatably connected to the first mounting seat 41 around a third axis, and the other end of the driving connecting rod 43 is rotatably connected to the second mounting seat 42 around a fourth axis, and the third axis is arranged in parallel with the fourth axis, so that the driving connecting rod 43 is pivotally connected between the wind deflector plate 2 and the driving sleeve 32.

[0065] Combination Figure 3 and Figure 7When the driving sleeve 32 moves to one side along the axial direction of the second axis, the position of the second connecting seat can be adjusted, and the second connecting seat drives the end of the driving link 43 to move, and the driving link 43 can rotate relative to the second connecting seat to realize the driving link 43 rotating around the fourth axis. At the same time, the driving link 43 can rotate around the third axis at the first connecting seat, thereby supporting the driving link 43 between the driving sleeve 32 and the wind resistance plate 2, and driving the wind resistance plate 2 to rotate and open relative to the mounting bracket 1 around the first axis through the driving link 43.

[0066] It is understandable that when the drive sleeve 32 moves along the other side of the axial direction of the second axis, the reverse action of the above-mentioned opening action can be performed to close the wind spoiler 2. Therefore, by cooperating with the drive sleeve 32 and the connecting rod assembly 4, the connecting rod assembly 4 can drive the wind spoiler 2 to open or close.

[0067] The third axis and the fourth axis are arranged in parallel, thereby ensuring the movement stability of the driving connecting rod 43, and the driving force can be stably transmitted to the wind resistance plate 2 through the driving connecting rod 43. At the same time, the third axis and the fourth axis are respectively arranged in parallel with the first axis, and the third axis and the fourth axis are respectively arranged perpendicular to the second axis.

[0068] In a further embodiment of the present application, the central axis of the drive link 43 is coplanar with the central axis of the drive sleeve 32, and the first axis is perpendicular to the plane where the drive link 43 and the drive sleeve 32 are located, so that the supporting force applied to the wind resistance plate 2 by the drive link 43 is more stable.

[0069] It is understandable that, during the rotation of the driving connecting rod 43 relative to the driving shaft sleeve 32, the central axis of the driving connecting rod 43 and the central axis of the driving shaft sleeve 32 remain coplanar. Figure 4 In the side cross-sectional view of the driving connecting rod 43, the wind resistance plate 2 and the driving shaft sleeve 32, multiple rotation positions (such as: at the first axis, the third axis and the fourth axis) can be arranged in three non-collinear points, that is, a triangular support structure is formed between the wind resistance plate 2 and the driving device through the connecting rod assembly 4. The triangular support structure has good anti-deformation ability, which can ensure the stability of the driving process of the wind resistance plate 2 and improve the strength of the wind resistance device 100 after it is opened.

[0070] In some embodiments of the present application, the wind resistance device 100 also includes a hydraulic connection assembly 5, which is telescopically connected between the wind resistance plate 2 and the mounting bracket 1, and the hydraulic connection assembly 5 is used to support the wind resistance plate 2 to enhance the strength of the wind resistance device 100 after it is opened.

[0071] It is understandable that when the wind resistance device 100 is opened, the wind resistance plate 2 is subjected to a relatively large airflow impact force, so that the wind resistance plate 2 is easily over-opened under the impact of the airflow, and the wind resistance plate 2 is easily deformed.

[0072] In the present application, the hydraulic connection assembly 5 is connected between the mounting bracket 1 and the wind resistance plate 2, and plays the role of connecting the mounting bracket 1 and the wind resistance plate 2, improving the connection reliability between the mounting bracket 1 and the wind resistance plate 2, while preventing the wind resistance plate 2 from being excessively opened, thereby improving the structural strength and reliability of the wind resistance device 100.

[0073] In the process of opening the wind resistance device 100, the wind resistance plate 2 rotates relative to the mounting bracket 1, and the hydraulic connection assembly 5 gradually extends as the opening angle of the wind resistance plate 2 increases, so as to support between the wind resistance plate 2 and the mounting bracket 1; in the process of closing the wind resistance device 100, the wind resistance plate 2 rotates relative to the mounting bracket 1, and the hydraulic connection assembly 5 gradually shortens as the opening angle of the wind resistance plate 2 decreases. In other words, the hydraulic connection assembly 5 can support the wind resistance plate 2 in the wind resistance device 100, and play a buffering role in the process of opening or closing the wind resistance plate 2 and the mounting bracket 1, so as to ensure the stability of the wind resistance plate 2 when it is opened or closed.

[0074] It can be understood that in the wind resistance device 100 , the actuator for opening or closing the wind resistance plate 2 is the driving component 3 , and the hydraulic connection component 5 mainly serves to further improve the connection reliability between the wind resistance plate 2 and the mounting bracket 1 .

[0075] like Figure 7 As shown, in some embodiments of the present application, the hydraulic connection assembly 5 includes: a hydraulic cylinder 51 and a piston rod 52, the end of the hydraulic cylinder 51 is rotatably connected to the wind resistance plate 2, the piston rod 52 is telescopically arranged at the hydraulic cylinder 51, and one end of the piston rod 52 is rotatably connected to the mounting bracket 1 to ensure the support and buffering effect of the hydraulic connection assembly 5 between the wind resistance plate 2 and the mounting bracket 1.

[0076] It can be understood that the hydraulic connection assembly 5 is connected to the wind deflector plate 2 and the mounting bracket 1 at both ends of the telescopic direction, and the hydraulic connection assembly 5 can be telescopically adjusted as the position between the wind deflector plate 2 and the mounting bracket 1 changes. Since the wind deflector plate 2 and the mounting bracket 1 rotate together, the angle of the hydraulic connection assembly 5 relative to the mounting bracket 1 will gradually change as the wind deflector plate 2 rotates. Figure 4 and Figure 7 It can be seen that as the opening angle of the wind resistance plate 2 increases, the hydraulic connection assembly 5 also rotates relative to the mounting bracket 1, and the distance between the two connection ends of the hydraulic connection assembly gradually increases.

[0077] In some embodiments of the present application, the two connection ends of the hydraulic connection assembly 5 are rotatably connected to the wind resistance plate 2 and the mounting bracket 1. The rotation connection structure can be constructed as a ball head and a ball head seat, a connecting shaft and a shaft seat, etc., to meet the rotation requirements of the hydraulic connection assembly 5 relative to the wind resistance plate 2 and the mounting bracket 1.

[0078] Preferably, the rotation axes at both ends of the hydraulic connection assembly 5 can be arranged in parallel with the third axis and the fourth axis, so as to further enhance the supporting stability of the hydraulic connection assembly 5 on the wind resistance plate 2 and the mounting bracket 1 .

[0079] It can be understood that the distance between the two connecting ends of the hydraulic connecting assembly 5 and the first rotation axis remains unchanged. As the opening angle of the wind resistance plate 2 relative to the mounting bracket 1 increases, the distance between the two connecting ends gradually increases. Correspondingly, the length of the hydraulic connecting assembly 5 will be extended, that is, the piston rod 52 extends outward from the hydraulic cylinder 51.

[0080] like Figure 4 and Fig. 9 As shown, in some embodiments of the present application, the mounting bracket 1 is provided with a mounting groove 11, the mounting groove 11 is recessed from the mounting bracket 1 to the side away from the wind resistance plate 2, and the mounting groove 11 can form an accommodating space for arranging the hydraulic connection assembly 5 between the wind resistance plate 2 and the mounting bracket 1. Therefore, when the wind resistance device 100 is in a closed state, the hydraulic connection assembly 5 can be accommodated through the mounting groove 11.

[0081] Reference Figure 4 It can be seen that one end of the hydraulic connection assembly 5 connected to the mounting bracket 1 (such as: the mounting seat structure) is arranged in the mounting groove 11, and when the wind resistance plate 2 is in a closed state, one end of the hydraulic connection assembly 5 connected to the wind resistance plate 2 (such as: the mounting seat structure) is also arranged in the mounting groove 11, thereby realizing the accommodation of the hydraulic connection assembly 5.

[0082] It can be understood that by opening a concave mounting groove 11 in the mounting bracket 1, the hydraulic connection assembly 5 can be fully hidden, so that the wind resistance plate 2 and the mounting bracket 1 remain in contact when the wind resistance device 100 is in a closed state, effectively reducing the wind resistance at the wind resistance plate 2.

[0083] like Figure 5As shown, in some embodiments of the present application, the mounting bracket 1 is provided with an avoidance groove 12, and the avoidance groove 12 is used to avoid the connecting rod assembly 4. It can be understood that the driving assembly 3 is arranged on the lower side of the mounting bracket 1 (i.e., the side away from the wind resistance plate 2) to avoid the driving assembly 3 occupying the space between the wind resistance plate 2 and the mounting bracket 1, which causes the wind resistance plate 2 to be unable to be fully closed (i.e., the wind resistance plate 2 and the mounting bracket 1 are arranged in a close fit). At the same time, the connecting rod assembly 4 needs to be connected between the wind resistance plate 2 and the driving device, so the driving connecting rod 43 in the connecting rod assembly 4 needs to be arranged through the mounting bracket 1, and the avoidance groove 12 can play a role in avoiding the connecting rod assembly 4.

[0084] In some embodiments of the present application, there are multiple hydraulic connection assemblies 5, and the multiple hydraulic connection assemblies 5 are arranged at intervals along the axial direction of the first axis, so as to improve the connection reliability between the wind resistance plate 2 and the mounting bracket 1 through the multiple hydraulic connection assemblies 5, and improve the supporting effect of the hydraulic connection assembly 5 on the wind resistance plate 2.

[0085] like Figure 5 As shown, in a specific embodiment of the present application, there are two hydraulic connection assemblies 5, and a set of drive assemblies 3 and connecting rod assemblies 4 are provided in the windage braking system.

[0086] Among them, the driving assembly 3 and the connecting rod assembly 4 are arranged in the middle position of the wind resistance device 100 in the axial direction of the first axis, so that the driving force can be transmitted to the middle position of the wind resistance plate 2, ensuring the reliability and stability of the driving force transmission. At the same time, the two hydraulic connection assemblies 5 are symmetrically arranged on both sides of the driving assembly 3 and the connection assembly in the axial direction of the first axis, and the two hydraulic connection assemblies 5 are arranged near the two ends of the wind resistance device 100 to enhance the supporting effect of the hydraulic connection assembly 5 on the wind resistance plate 2, ensure the connection reliability between the wind resistance plate 2 and the mounting bracket 1, and the stability of the opening and closing action of the wind resistance plate 2.

[0087] Combination Figure 3 , Figure 4 , Figure 7 and Figure 8 Describe the opening process of the wind resistance device 100 of the embodiment of the present application:

[0088] The driving motor 31 outputs a driving force to drive the driving sleeve 32 to move along the axial direction of the second axis, and the driving sleeve 32 drives one end of the driving connecting rod 43 to move synchronously, so as to support and drive the wind resistance plate 2 through the driving connecting rod 43. As the rotation angle of the driving connecting rod 43 increases, the opening angle of the wind resistance plate 2 gradually increases, so as to realize the opening action of the wind resistance device 100.

[0089] At the same time, during the opening process of the wind deflector plate 2, the length of the hydraulic connection assembly 5 connected between the wind deflector plate 2 and the mounting bracket 1 gradually increases. The hydraulic connection assembly 5 is supported between the wind deflector plate 2 and the mounting bracket 1, thereby improving the posture reliability and stability of the wind deflector plate 2 braking device in the open state, thereby ensuring the structural strength of the wind deflector device 100.

[0090] The closing action of the wind resistance device 100 is a reverse action of the above-mentioned action.

[0091] The wind resistance device 100 according to the embodiment of the present application has at least the following advantages:

[0092] (1) The wind resistance plate 2 can be opened or closed relative to the mounting bracket 1. When the wind resistance plate 2 is opened, the wind resistance plate 2 can be arranged relative to the direction of travel of the vehicle to increase the wind resistance of the vehicle in the direction of travel and improve the braking effect of the vehicle; when the wind resistance plate 2 is closed, the wind resistance plate 2 is arranged in close contact with the mounting bracket 1, that is, the wind resistance is not increased;

[0093] (2) The hydraulic connection assembly 5 is supported between the wind resistance plate 2 and the mounting bracket 1, which can improve the structural strength of the wind resistance device 100 in the open state, prevent the wind resistance plate 2 from over-turning under the impact of airflow, and can also play a buffering role for the opening or closing of the wind resistance plate 2;

[0094] (3) The wind deflector plate 2 is driven by the driving assembly 3 and the connecting rod assembly 4, and the driving stability is good and the reliability is high, which can ensure the stability of the wind deflector plate 2 during the flipping process.

[0095] According to the vehicle of the embodiment of the present application, the vehicle includes the above-mentioned wind resistance device 100. By providing the wind resistance device, the braking performance of the vehicle can be further improved, the braking distance of the vehicle can be shortened, more reaction time can be reserved for the driver to prevent accidents, and the risk of vehicle accidents can be further reduced.

[0096] The wind resistance device may be involved in the vehicle's stability system control unit. When the vehicle needs to brake, the stability system control unit may output a control signal to control the wind resistance device to open the wind resistance plate. It should be noted that the control method of the wind resistance device is not limited to this and is not specifically limited here.

[0097] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
