Description

Technical Field

[0001] The utility model belongs to the technical field of tail wing lifting mechanisms, and in particular relates to a tail wing lifting structure with a larger turning angle and a higher lifting height. Background Art

[0002] The rear wing of a car is part of the aerodynamic kit. The function of the rear wing of a car is to make the air resistance form downward pressure when the car is driving at high speed, try to offset the lift, effectively control the downward pressure of the airflow, reduce the drag coefficient accordingly, and increase the stability of the car at high speed. Since the rear wing can reduce the air resistance of the car, the installation of a rear wing on a high-speed car is also helpful to save fuel. In reality, car owners do not like to install a high-position rear wing. Most car owners choose to install an electric rear wing because it can control the rise and fall of the electric rear wing and the deployment and folding of the electric rear wing panel assembly according to the speed of the car. When the electric rear wing is fully raised, the electric rear wing panel assembly is deployed, providing downward pressure to increase the friction between the tire and the ground, thereby enhancing the stability of the entire vehicle. However, when the electric rear wing is deployed and folded, it often shakes due to the influence of road conditions and wind, and the electric rear wing is unstable.

[0003] Currently, most of the rear wing lifting mechanisms on the market are four-link structures. Due to the space limitation of the tailgate, the four-link structure can only provide a limited height and flip angle for the rear wing. After the rear wing is raised, the angle of the spoiler and the air flow angle of the car are only about 7 to 20°. At a speed of 100Km / h, the downforce provided by the lifting spoiler to the car is only 20N to 80N (the downforce caused by the different contact surface and flip angle of the spoiler is different, and the area of ​​the general car rear wing is 0.2㎡ to 0.3㎡).

[0004] Therefore, there is an urgent need for a tail lift mechanism that can improve the lifting height and the turning angle of the tail spoiler. Utility Model Content

[0034] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0036] As shown in the figure, a tail lifting structure with a larger flip angle and a higher lifting height includes: a support base 9, the support base 9 has a fixed plate folded on both sides; a main driving arm 2, the lower end of the main driving arm 2 is connected to the main driving shaft 1, and is fixed to the left fixed plate of the support base 9 through a pin; an auxiliary driving arm 3, the auxiliary driving arm 3 is connected to the upper end of the main driving arm 2 through a pin; a main support rod 4, the rear end of the main support rod 4 is fixed to the left fixed plate of the support base 9 through a pin and is located on the rear side of the main driving arm 2, and the upper end of the auxiliary driving arm 3 is connected to the middle section of the main support rod 4 through a pin; and an auxiliary connecting rod assembly, the auxiliary connecting rod assembly is used to cooperate with the main support rod 4 to connect the mounting bracket 8.

[0037] In one embodiment of the utility model, the support base 9 is mounted to the vehicle body, the mounting bracket 8 fixes the rear spoiler, and the internal multi-link mechanism completes the lifting of the rear wing. The auxiliary link assembly achieves a larger flip angle and a higher lifting height.

[0038] The auxiliary connecting rod assembly includes:

[0039] An auxiliary linkage rod 5, the middle section of which is connected to the main support rod 4 through a pin shaft and is located at the front end of the auxiliary driving arm 3;

[0040] Auxiliary lower support rod 7, the auxiliary lower support rod 7 is respectively connected to the rear end of the auxiliary linkage rod 5 and the right side fixing plate of the support base 9 through a pin shaft;

[0041] An auxiliary upper support rod 6, the auxiliary upper support rod 6 is connected to the front end of the auxiliary linkage rod 5 through a pin shaft;

[0042] The two ends of the mounting bracket 8 are respectively connected to the front end of the main support rod 4 and the auxiliary upper support rod 6 through a pin shaft.

[0043] In detail, the support base 9 is kept fixed, the main drive shaft 1 and the main drive arm 2 are connected by splines and fixed on the support base 9, and the main drive shaft 1 rotates to drive the main drive arm 2 to rotate; the main drive arm 2 and the auxiliary drive arm 3 are connected by a pin shaft, and the main drive arm 2 drives the auxiliary drive arm 3 to rotate; the main support rod 4 and the auxiliary drive arm 3, the auxiliary linkage rod 5, the mounting bracket 8 and the support base 9 are connected together by a pin shaft. When the auxiliary drive arm 3 pushes the main support rod 4 to do a lifting movement, it will push the mounting bracket 8 to do a lifting movement. The mounting bracket 8 is fixed to the spoiler of the rear wing, so as to realize the lifting and flipping movement of the spoiler. The side of the main drive arm 2 has a TPV limit column 11, which is used to support the pin shaft of the descending auxiliary drive arm 3, that is, during the falling process, the pin shaft connection between the auxiliary drive arm 3 and the main support rod 4 flips and falls, and will fall to the upper side of the main drive arm 2, and then supported by the TPV limit column 11, which plays a protective effect.

[0044] The auxiliary lower support rod 7 is fixed to the support base 9 by a pin, the auxiliary upper support rod 6 is fixed to the mounting bracket 8, and the two ends of the auxiliary linkage rod 5 are respectively connected to the auxiliary lower support rod 7 and the auxiliary upper support rod 6. The auxiliary lower support rod 7, the auxiliary upper support rod 6 and the auxiliary linkage rod 5 form an auxiliary support system, and the system is connected to the main support rod 4 by a pin. The invention of the lifting mechanism is that on the basis of the four connecting rods, the auxiliary connecting rod is changed from a supporting rod to a retractable supporting system composed of three parts.

[0045] When the main driving arm 2 and the auxiliary driving arm 3 push the main support rod 4 to lift the mounting bracket 8, the distance between the mounting bracket 8 and the supporting base 9 will increase, the auxiliary support system will change from a contracted state to an extended state, and the auxiliary linkage rod 5 will rotate, causing the auxiliary upper support rod 6 and the auxiliary lower support rod 7 to extend accordingly.

[0047] As mentioned above, by using three simple struts to rotate around the middle axis, the principle of extending and retracting the length of the auxiliary rod is realized. When the tail wing is closed, it can be accommodated in a smaller space, and when it is propped up, it can be stretched out, providing the spoiler of the tail wing with a higher lifting height and a larger flip angle.

[0048] In addition, the system is connected to the main support rod 4 by a pin shaft, distributing the downward pressure of the tail wing to the main support rod 4 and the auxiliary lower support rod 7. The lifting mechanism is evenly stressed and the mechanism system is more stable.

[0049] Preferably, the middle section of the auxiliary linkage rod 5 is provided with a concave reinforcing rib to improve the strength. The two sides of the auxiliary driving arm 3 are concave to facilitate smooth rotation.

[0050] Furthermore, the rear end of the main support rod 4 is configured as an upwardly protruding arched portion, and the arched portion is located between the connection of the support base 9 and the connection of the auxiliary driving arm 3.
