Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a spoiler. Background Technology

[0002] Car spoilers, based on aerodynamic principles, address the air resistance encountered by cars during driving. This resistance can be categorized into longitudinal, lateral, and vertical forces, and is directly proportional to the square of the air resistance. Therefore, the faster the car travels, the greater the air resistance. Generally, the impact of air resistance becomes very noticeable when the speed exceeds 60 km / h. To effectively reduce and overcome the effects of air resistance at high speeds, car spoilers (i.e., rear wings) are designed and used. Their function is to generate a fourth force on the car—the adhesion force to the ground. This counteracts some of the lift force, controls the car's upward movement, reduces wind resistance, and allows the car to stay close to the road, thus improving driving stability. Furthermore, with the continuous rise in fuel prices, the fuel-saving effect of rear wings due to reduced air resistance is becoming increasingly apparent. Taking a 1.8-liter sedan as an example, data shows that after installing a spoiler, the air resistance coefficient is reduced by 20%. On ordinary roads, the reduction in fuel consumption may not be obvious, but when the car is traveling at 120 kilometers per hour on the highway, it can save 14% of fuel. At this time, the fuel-saving effect of the car spoiler is very obvious.

[0003] However, some current spoilers are fixed to the rear of the car and cannot automatically adjust according to vehicle speed and wind speed.

[0004] Therefore, there is an urgent need for a spoiler to address, to some extent, the technical problems existing in the current technology. Summary of the Invention

[0055] The following is combined Figures 1-9 This application provides a detailed description of a flow disruptor.

[0056] This application provides a flow disruptor.

[0057] Specifically, the spoiler includes winglets 1 and a spoiler 3, wherein the spoiler 3 is disposed on the main body of the vehicle body 2. More specifically, the spoiler 3 is disposed at the rear of the main body of the vehicle body 2. Further, the length direction of the spoiler 3 refers to the width direction 12 of the main body of the vehicle body, and the width direction of the spoiler 3 refers to the length direction 11 of the main body of the vehicle body; wherein the winglets 1 are disposed at both ends in the length direction of the spoiler 3.

[0058] Specifically, the spoiler also includes a telescopic component that can extend and retract along the height of the vehicle body. Furthermore, one end of the telescopic component along its extension and retraction direction is connected to the vehicle body 2, and the other end is connected to the spoiler 3.

[0059] Specifically, the turbulence drive component is connected to the telescopic component.

[0060] In actual use, the spoiler drive component can drive the telescopic component to move, so that the spoiler 3 is attached to or spread out of the body body 2.

[0061] In summary, this application allows for real-time adjustment of the spoiler 3's movement based on vehicle driving conditions, thereby increasing vehicle stability and improving driving safety.

[0062] In this embodiment, a first slide rail is provided on the vehicle body 2; the turbulence drive assembly includes a first connecting shaft 6, a collar 7, a first rack 8, a first gear 9, and a first drive motor 10.

[0063] Specifically, the first slide rail and the first rack 8 are arranged parallel to and spaced apart along the length direction 11 of the vehicle body 2, and both the first slide rail and the first rack 8 extend along the width direction of the vehicle building's straight stairs.

[0064] Specifically, the telescopic assembly has a sliding end 13 that can move along the length direction of the first slide, that is, the sliding end 13 of the telescopic assembly can slide within the first slide along the length direction of the first slide; the telescopic assembly also has a connecting end 14 that is opposite to the sliding end 13 and is hinged to the spoiler 3, that is, the connecting end 14 is rotatably connected to the spoiler 3.

[0065] Specifically, the sliding end 13 is rotatably connected to the first connecting shaft 6, and the collar 7 is sleeved on the first connecting shaft 6 and rotatably connected to the connecting shaft;

[0066] Specifically, the first drive motor 10 is fixedly connected to the collar 7, and the output end of the first drive motor 10 moves along the length direction of the first rack 8 through the first gear 9;

[0067] Specifically, the first slide has an initial end 15 and a termination end 16 opposite to the initial end 15, and the first rack 8 has a starting end and a stop end opposite to the starting end;

[0068] In actual use, in the initial state: the telescopic component is in the retracted state, the sliding end 13 of the telescopic component is located at the initial end 15, and the connecting end 14 of the telescopic component is located on the side of the termination end 16. That is, at this time, the telescopic component lies horizontally in the first slide, and the spoiler 3 is in contact with the body body 2. In addition, the first drive motor 10 is located next to the first slide and on the side of the initial end 15 of the first slide.

[0069] As the spoiler 3 slowly expands onto the body 2: the first drive motor 10 moves along the first rack 8 from the initial end 15 to the final end 16 via the first gear 9. During this movement, since the first drive motor 10 is fixedly connected to the collar 7, the collar 7 also moves along with the first drive motor 10. Furthermore, since the collar is rotatably connected to the first connecting shaft 6, and the first connecting shaft 6 is rotatably connected to the sliding end 13 of the telescopic assembly, and the connecting end 14 of the telescopic assembly is rotatably connected to the spoiler 3, the collar 7, the first connecting shaft 6, the telescopic assembly, and the spoiler 3 can be considered as a four-bar linkage during the operation of the first drive motor 10. During operation, when the sliding end 13 of the first drive motor 10 moves from the initial end 15 to the terminal end 16 (which can be understood as the first drive motor 10 pulling the first connecting shaft 6 along the length of the first slide rail via the ring sleeve), the telescopic component changes from lying horizontally in the first sliding state to a vertical state, that is, the telescopic component is perpendicular to the vehicle body 2. When the telescopic component is perpendicular to the vehicle body 2, the spoiler 3 changes from being attached to the vehicle body 2 to being supported by the vehicle body 2. That is, the action of the spoiler 3 can be adjusted in real time according to the vehicle driving conditions (the spoiler 3 is opened from the vehicle body 2), which increases the stability of the vehicle body and improves driving safety.

[0070] In this embodiment, the telescopic component includes a telescopic joint 17.

[0071] Specifically, there are multiple telescopic joints 17, which are sequentially installed along the height direction 18 of the vehicle body.

[0072] Specifically, the telescopic joint 17 away from the main body 2 is hinged to the spoiler 3, and the telescopic joint 17 close to the main body 2 is hinged to the first connecting shaft 6, so that when the telescopic assembly moves from the initial end 15 to the terminal end 16, the spoiler 3 can be extended on the main body 2.

[0073] In summary, during the process of the spoiler 3 opening the main body 2 of the vehicle body, the telescopic joint 17 can be extended slowly at the same time to increase the opening speed of the spoiler 3 opening the main body 2 of the vehicle body. Alternatively, the telescopic component can be changed from a horizontal state to a vertical state first. After the telescopic component is in a vertical state, the telescopic joint 17 inside the telescopic component can be extended by the drive motor.

[0074] In this embodiment, multiple telescopic components are provided, and multiple first slide rails are provided. The telescopic components and the first slide rails are respectively provided in a one-to-one correspondence; the multiple telescopic components are arranged in a matrix.

[0075] In summary, the use of multiple telescopic components arranged in a matrix can make the spoiler 3 more stable and balanced when the main body 2 of the vehicle body is opened, without the problem of tilting.

[0076] Specifically, the following detailed explanation uses four telescopic components as an example. These four components are arranged in a 2×2 matrix. The four telescopic components are telescopic component 19, telescopic component 20, telescopic component 30, and telescopic component 31. Correspondingly, there are also four first slides: first slide 12, first slide 23, first slide 34, and first slide 45. Telescopic component 19 is slidably positioned on first slide 12, telescopic component 20 is slidably positioned on first slide 23, and telescopic component 31 is slidably positioned on... The first slide rail 34 is placed in the third slide rail, and the fourth telescopic component 31 is slidably set in the fourth slide rail. The first telescopic component 19 and the second telescopic component 20 share the same first connecting shaft 6, and the third telescopic component 30 and the fourth telescopic component 31 share a first connecting shaft 6. There are two first drive motors 10. One first drive motor 10 is rotatably connected to the first connecting shaft 6 shared by the first telescopic component 19 and the second telescopic component 20 through a collar 7, and the other first drive motor 10 is rotatably connected to the first connecting shaft 6 shared by the third telescopic component 30 and the fourth telescopic component 31 through a collar 7.

[0077] In summary, in the actual work process, it is possible to adapt to the specific needs and... Figure 5 Based on the orientation of the components, telescopic components 19 and 30 are located near the front of the vehicle (telescopic component 19 is located on the driver's side, and telescopic component 30 is located on the passenger side), while telescopic components 20 and 31 are located near the rear of the vehicle. The following driving configuration exists:

[0078] (1) In case of emergency braking, the two drive motors can first be used to prop up the spoiler 3 onto the main body 2 of the vehicle. Then, the telescopic joints 17 of the second telescopic assembly 20 and the fourth telescopic assembly 31 are extended, while the telescopic joints 17 of the first telescopic assembly 19 and the third telescopic assembly 30 are not extended. Ultimately, the spoiler 3 is in a tilted vertical state, with the rear end of the spoiler 3 higher than the front end (in extreme cases, the spoiler 3 is directly perpendicular to the main body 2 of the vehicle), thereby increasing wind resistance and assisting in timely braking (the situation of emergency braking is exactly the opposite of acceleration). It is worth noting that at this time, the drive motors of the telescopic assemblies and the first drive motor 10 are connected to the vehicle's electronic control system, especially the speed control system in the vehicle control system. Once the speed system receives an emergency braking signal, the first drive motor 10 and the drive motor will automatically start.

[0079] (2) When a right turn is required, the two drive motors can first be used to prop up the spoiler 3 onto the main body 2 of the vehicle. Then, the telescopic joints 17 of the second telescopic assembly 20 and the first telescopic assembly 19 are extended, while the telescopic joints 17 of the fourth telescopic assembly 31 and the third telescopic assembly 30 are not extended. Ultimately, the spoiler 3 is in a tilted vertical state, with the left side of the spoiler 3 higher than the right side (in extreme cases, the spoiler 3 is directly perpendicular to the main body 2 of the vehicle), thereby increasing wind resistance and assisting in the purpose of a right turn (the situation for a left turn is exactly the opposite of that for a right turn). It is worth noting that at this time, the drive motors of the telescopic assemblies and the first drive motor 10 are connected to the vehicle's electronic control system, especially the speed control system in the vehicle control system. Once the speed system receives a right turn signal, the first drive motor 10 and the drive motor will automatically start.

[0080] (3) When going uphill, the two drive motors can first be used to prop up the spoiler 3 onto the main body 2 of the vehicle. Then, the telescopic joints 17 of the third telescopic component 30 and the first telescopic component 19 are extended, while the telescopic joints 17 of the second telescopic component 20 and the fourth telescopic component 31 are not extended. Finally, the spoiler 3 is in a tilted vertical state, with the front end of the spoiler 3 higher than the rear end (in extreme cases, the spoiler 3 is directly perpendicular to the main body 2 of the vehicle), thereby increasing wind resistance and assisting in the purpose of turning right (the situation is exactly the opposite for going uphill and going downhill). It is worth noting that at this time, the drive motors of the telescopic components and the first drive motor 10 are connected to the vehicle's electronic control system, especially the speed control system in the vehicle control system. Once the speed system receives the uphill signal, the first drive motor 10 and the drive motor will start automatically.

[0081] In this embodiment, the spoiler also includes a push-drive component.

[0082] Specifically, the horizontal thrust drive assembly is connected to the winglet 1, and the horizontal thrust assembly can drive the winglet 1 to extend or retract the spoiler 3 along the width direction 12 of the main body of the vehicle.

[0083] Specifically, the horizontal drive assembly includes a second rack 36, a second drive motor 37, and a support frame 38; wherein, the spoiler 3 has a second slide rail on the two side walls of the spoiler 3 corresponding to the position of the winglet 1; the winglet 1 is slidably disposed in the second slide rail through the second connecting shaft, that is, the winglet 1 is fixedly connected to the second connecting shaft, and the two ends of the second connecting shaft are slidably disposed in the second slide rail respectively.

[0084] The second connecting shaft is also fitted with a sleeve, the second connecting shaft is rotatably connected to the sleeve, and the support frame 38 is rigidly connected to the sleeve.

[0085] The second drive motor 37 is mounted on the support frame 38, meaning that the second drive motor 37 is fixed together with the support frame 38. The second rack 36 is mounted on the spoiler 3 at the position corresponding to the winglet 1 and extends along the length of the spoiler 3. The second drive motor 37 can move on the second rack 36 through the second gear.

[0086] In actual use, when it is necessary to drive the winglet 1 to extend out of the spoiler 3, the second drive motor 37 is first turned on, so that the second drive motor 37 moves along the second rack 36 towards the end of the spoiler 3 under the action of the second gear (in conjunction with...). Figure 7 As shown, the spoiler 3 moves from the right side to the leftmost side; then, since the support frame 38 is fixed together with the second drive motor 37, the support frame 38 will also move toward the end of the spoiler 3; finally, since the support frame 38 is connected to the second connecting shaft through the sleeve, the movement of the support frame 38 will drive the second connecting shaft to move in the second slide, so that the second connecting shaft moves toward the end of the spoiler 3 at the same time. Since the second connecting shaft is fixedly connected to the winglet 1, the movement of the second connecting shaft will cause the winglet 1 to extend out of the spoiler 3 (the process of the winglet 1 retracting into the spoiler 3 is the reverse of the above process, and will not be described in detail here).

[0087] In this embodiment, four winglets 1 are provided. Two winglets 1 are arranged as a group at one end of the spoiler 3 along its length, and the other two winglets 1 are arranged as another group at the other end of the spoiler 3 along its length. The two winglets 1 in each group are respectively arranged on the upper and lower end surfaces of the spoiler 3 (the two winglets 1 are arranged symmetrically). Among the two winglets 1 in the group, the first winglet 48 is slidably disposed on the first second slide rail 43 via the first second connecting shaft 39, and the second winglet 49 in the group is slidably disposed on the second second slide rail 47 via the second second connecting shaft 45.

[0088] Specifically, the spoiler also includes a rotary drive assembly; the rotary drive assembly includes a third gear 40, a fourth gear 41, and a third drive motor 42; the third gear 40 is mounted on a first second connecting shaft 39, the fourth gear 41 is mounted on a second second connecting shaft 45, and the third gear 40 and the fourth gear 41 are meshed together; the third drive motor 42 meshes with the fourth gear 41 through gears (the distance between the gears meshing with the third gear 40 and the distance between the gears meshing with the fourth gear 41 is the same, and will not be described in detail here).

[0089] In actual use, when it is necessary to drive the winglet 1 to extend out of the spoiler 3, the second drive motor 37 is first turned on, so that the second drive motor 37 moves along the second rack 36 towards the end of the spoiler 3 under the action of the second gear (in conjunction with...). Figure 7 As shown, it moves from the right side of the spoiler 3 to the leftmost side of the spoiler 3; during this process, the third drive motor 42 is not turned on. Since the third drive motor 42 meshes with the fourth gear 41 through a gear, and the fourth gear 41 meshes with the third gear 40, when the third drive motor 42 is not started, the third gear 40, the fourth gear 41 and the third drive motor 42 are mutually limited. That is to say, at this time, the first second connecting shaft 39 and the second second connecting shaft 45 are integrated and will move synchronously without rotational movement; then, since the support frame 38 and the second drive motor 37 are fixed together, the support frame 38 will also move towards the end of the spoiler 3; finally, since the support frame 38 is connected to the first sleeve and the first The second connecting shaft 39 is connected, and the support frame 38 is connected to the second connecting shaft 45 through the second sleeve. As the support frame 38 moves, it will drive the first second connecting shaft 39 to move in the first second slide 43, and the second second connecting shaft 45 to move in the second second slide 47 and move towards the end of the spoiler 3. Since the first second connecting shaft 39 is fixedly connected to the first winglet 48, and the second second connecting shaft 45 is fixedly connected to the second winglet 49, the first second connecting shaft 39 and the second second connecting shaft 45 will cause the first winglet 48 and the second winglet 49 to extend out of the spoiler 3 (the process of the winglet 1 retracting into the spoiler 3 is the reverse of the above process and will not be described in detail here).

[0090] When winglets 48 and 49 extend from spoiler 3, the third drive motor 42 is activated. The activation of the third drive motor 42 drives the gears meshing with it to rotate, which in turn drives the third gear 40 and the fourth gear 41 to rotate sequentially. The rotation of the third gear 40 and the fourth gear 41 causes winglets 48 and 49 to flip. For example, if the third drive motor 42 drives the connected gears to rotate clockwise, the fourth gear 41 on winglet 49 will rotate clockwise, causing winglet 49 to flip downwards. Since the fourth gear 41 of winglet 49 meshes with the third gear 40 of winglet 48, the third gear 40 of winglet 48 will rotate clockwise, causing winglet 48 to flip upwards. In summary, this causes the two winglets 1 to deploy synchronously. The recovery process is the reverse and will not be elaborated further.

[0091] It is worth noting that: the winglet 1 includes a main board and a deflector plate connected to the main board. The main board is connected to the second connecting shaft. The deflector plate is streamlined. When the first winglet 48 and the second winglet 49 are both fastened to the spoiler plate 3, the two are precisely connected to form a sealed structure.

[0092] In this embodiment, the spoiler also includes a controller, which is communicatively connected to the first drive motor 10, the second drive motor 37, the third drive motor 42 and the engine controller.

[0093] Specifically, in actual operation, the controller controls the first drive motor 10, the second drive motor 37, and the third drive motor 42 in response to the signal from the engine controller.

[0094] In summary, under certain circumstances, this application can optionally deploy the winglet 1, which can reduce the vortices generated during vehicle driving. In summary, this application can adjust the angle in real time according to the vehicle's driving conditions, increasing vehicle stability.
