Description

Technical Field

[0001] The present invention relates to the technical field of automotive aerodynamics, and particularly to an automotive electric spoiler. Background Art

[0002] Existing automotive electric spoilers mostly adopt single-segment, left-right segmented or fixed structures, and cannot be adjusted in multiple levels according to different driving states and environmental conditions, which limits their ability to optimize aerodynamic performance and the drag coefficient during vehicle driving.

[0003] Reference patent document CN119749724A discloses an automotive spoiler with an adjustment mechanism. Among them, the tail of the left end of the wing plate is in a horizontal state, the front part of the right end of the wing plate is in an inclined state with the direction downward, and a level is horizontally fixedly connected to the bottom of the left end of the wing plate. This device can adjust the height and angle of the automotive spoiler. Reference patent document CN117818777A discloses a hidden automotive spoiler, which realizes functions such as waterproofing, hiding, height and angle adjustment of the spoiler through a translation and lifting mechanism and an elastic water blocking mechanism. However, the automotive spoilers in the above documents are all single-segment structures, and there are limitations in their lifting height and flipping angle, and cannot meet the requirements of some high-performance vehicles for higher lifting height and larger flipping angle of the spoiler.

[0004] Reference patent document CN119636932A discloses a vehicle spoiler assembly, which includes an intermediate wing disposed on a mounting base and two side wings symmetrically distributed at both ends of the intermediate wing respectively. Through the design of two arc-shaped grooves with different lengths, the side wings can first flip and then rotate, so as to increase the windward area of the spoiler and provide sufficient downforce for the whole vehicle; enhance the stability of the vehicle when driving at high speed. However, the automotive spoiler in the above document is a left-right segmented structure, and it is difficult to meet the requirements of complex road conditions and high-speed driving, especially when more precise angle control is required in different speed ranges, it is particularly insufficient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automotive electric spoiler in view of the above deficiencies.

[0006] The present invention is realized through the following technical solutions:

[0007] An automotive electric spoiler, which comprises:

[0008] A lower base assembly, fixed to the tailgate sheet metal;

[0009] An upper base assembly, connected to the lower base assembly through a lifting mechanism assembly;

[0010] A main spoiler assembly, fixed to the upper base assembly;

[0011] The outward-opening spoiler assembly is connected to the upper base assembly through a two-stage lifting mechanism assembly;

[0012] Among them, the first-stage lifting mechanism assembly is configured to drive the upper base assembly and the main spoiler assembly to perform the first-stage lifting,

[0013] and the second-stage lifting mechanism assembly is configured to drive the outward-opening spoiler assembly to perform the second-stage lifting after the first-stage lifting is completed.

[0014] Furthermore, for a certain automotive electric tail wing, the second-stage lifting mechanism assembly includes a driving lead screw motor fixed to the upper base assembly. The driving lead screw motor drives a driving lead screw along the length direction of the vehicle. The driving lead screw drives a driving slider to move along the length direction of the vehicle through a lead screw driving rod; one end of a driving link is hinged to the outward-opening spoiler assembly, and the other end is hinged to the driving slider; one end of a driven link is connected to the outward-opening spoiler assembly, and the other end is hinged to the lead screw driving rod through a connecting rod, and a sliding foot is provided to slide in a track groove provided in a guiding block, and the guiding block is fixed to the upper base assembly.

[0015] Furthermore, for a certain automotive electric tail wing, the second-stage lifting mechanism assembly is symmetrically arranged. The driving lead screw motor and the driving lead screw are arranged in the middle of the upper base assembly. A sliding guide rail is respectively arranged on both sides of the upper base assembly along the length direction of the vehicle; both ends of the lead screw driving rod are respectively connected to a driving slider, and the driving slider is slidably arranged on the sliding guide rail.

[0016] Furthermore, for a certain automotive electric tail wing, the shape of the track groove is configured to control the movement track of the outward-opening spoiler assembly, so that it simultaneously generates a composite movement of upward movement and angular flipping.

[0017] Furthermore, for a certain automotive electric tail wing, the driving lead screw motor drives the driving lead screw to drive the lead screw driving rod to perform a linear movement, and then drives the outward-opening spoiler assembly to perform angular flipping through the driving slider and the driving link; at the same time, the lead screw driving rod drives the outward-opening spoiler assembly to move along the track groove of the guiding block through the connecting rod and the driven link, so as to realize the second-stage lifting.

[0018] Furthermore, for a certain automotive electric tail wing, the first-stage lifting mechanism assembly includes at least one set of link mechanisms, which are configured to lift the main spoiler assembly and the outward-opening spoiler assembly from the closed state attached to the vehicle tailgate to the first-stage lifting state.

[0019] Further, for the automotive electric spoiler described above, when the first-stage lifting is completed, the main spoiler assembly and the outward-opening spoiler assembly maintain the same angle; during the second-stage lifting process, the main spoiler assembly remains stationary while the outward-opening spoiler assembly continues to lift.

[0020] Further, for the automotive electric spoiler described above, the hinge point of the driving link with the outward-opening spoiler assembly and the connection point of the driven link with the outward-opening spoiler assembly are located at different positions on the outward-opening spoiler assembly to form a moment for flipping the outward-opening spoiler assembly.

[0021] Further, for the automotive electric spoiler described above, the track groove is in a Z shape extending towards the rear of the vehicle.

[0022] The advantages and effects of the present invention are as follows:

At the same time, when the automotive spoiler is closed, the entire mechanism can be compactly retracted, reducing space occupancy, enhancing the aesthetics and space utilization efficiency of the vehicle, and reducing manufacturing costs and maintenance difficulties.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present invention. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] As Figures 1 to 3As shown in the figure, the electric tail wing of the vehicle includes a lower base assembly 13, a first-stage lifting mechanism assembly 15, an upper base assembly 1, a main spoiler assembly 14, a second-stage lifting mechanism assembly 16, and an outward-opening spoiler assembly 3. The lower base assembly 13 is fixed to the tailgate sheet metal of the vehicle. The upper base assembly 1 is connected to the lower base assembly 13 through the first-stage lifting mechanism assembly 15. The main spoiler assembly 14 is fixed to the upper base assembly 1. The first-stage lifting mechanism assembly 15 can drive the upper base assembly 1 and the main spoiler assembly 14 to perform the first-stage lifting. Figure 2 Figure 1 shows the first-stage lifting state of the electric tail wing of the vehicle. The outward-opening spoiler assembly 3 is connected to the upper base assembly 1 through the second-stage lifting mechanism assembly 16. After the first-stage lifting is completed, the lifting mechanism assembly 1 can drive the outward-opening spoiler assembly 3 to perform the second-stage lifting. Figure 3 Figure 2 shows the second-stage lifting state of the electric tail wing of the vehicle, thus realizing the overall opening of the vehicle tail wing.

[0034] During the driving process of the lower base assembly 13 and the upper base assembly 1, the first-stage lifting mechanism assembly 15 and the second-stage lifting mechanism assembly 16 work simultaneously, and the three-stage opening of the tail wing is realized through the two-stage lifting mechanism. Users can select different lifting heights according to their needs. Among them, the upper base assembly 1 and the main spoiler assembly 14 are fixedly connected. When the upper base assembly 14 is lifted, the main spoiler assembly 14 must also be lifted, so as to keep the deflection angle of the main spoiler unchanged. The movement of the outward-opening spoiler assembly 3 is controlled by the second-stage lifting mechanism assembly 16. When the second-stage lifting mechanism assembly 16 works, the outward-opening spoiler can move along its largest arc trajectory and thus open. Through the above design, the electric tail wing of the vehicle of the present invention can not only realize three-stage opening, but also has a large tail wing area after opening, and can more effectively reduce the wind resistance at the rear of the vehicle.

[0035] In one embodiment, the lower base assembly 13 is composed of two support cross beams arranged on the left and right sides of the vehicle. The support cross beams are positioned on the tailgate sheet metal mounting plate through positioning holes. For the convenience of installation and structural optimization, it is preferably made of aluminum. The upper base assembly 1 is arranged on the lower base assembly 13, and the relative lifting movement between the two is mainly realized through the first-stage lifting mechanism assembly 15. Among them, the first-stage lifting mechanism assembly 15 includes at least one set of link mechanisms, configured to lift the main spoiler assembly 14 and the outward-opening spoiler assembly 3 from the closed state in contact with the vehicle tailgate to the first-stage lifting state. Specifically, in one embodiment, the first-stage lifting mechanism assembly 15 includes a lead screw motor fixed to the lower base assembly 13, a driving rotating shaft fixed to the lower base assembly 13, a driving sprocket fixed to the driving rotating shaft, and a sprocket fixed to the lower base assembly. One end of the chain is clamped on the driving sprocket, and the other end is clamped on the sprocket. Thus, the rotation of the lead screw motor drives the driving rotating shaft to rotate synchronously, and then drives the sprocket to rotate through the driving sprocket and the chain, realizing the operation of the first-stage lifting mechanism assembly 15.

[0036] As Figure 2 shown, when the first-stage lifting is completed, the main spoiler assembly 14 and the outward-opening spoiler assembly 3 maintain the same angle.

[0037] The main spoiler assembly 14 and the second-stage lifting mechanism assembly 16 are provided on the upper part of the upper base assembly 1. The second-stage lifting mechanism assembly 16 is configured to achieve the second lifting of the outward-opening spoiler assembly 3. As Figure 4 、 5 shown, the second-stage lifting mechanism assembly 16 includes a driving lead screw motor 9, a driving lead screw 10, a lead screw driving rod 11, a driving link 6, a driving slider 7, a driven link 4, a connecting rod 5, and a guiding block 8. The driving lead screw motor 9 is fixed to the upper base assembly 1, and the driving lead screw motor 9 can drive the driving lead screw 10 to reciprocate along the length direction of the vehicle. The driving lead screw 10 drives the driving slider 7 to reciprocate along the length direction of the vehicle through the lead screw driving rod 11. One end of the driving link 6 is hinged to the outward-opening spoiler assembly 3, and the other end is hinged to the driving slider 7. The guiding block 8 is fixed to the upper base assembly 1 and is provided with a track groove. One end of the driven link 4 is fixedly connected to the outward-opening spoiler assembly 3, and the other end is hinged to one end of the connecting rod 5. The other end of the connecting rod 5 is hinged to the lead screw driving rod 11. At the same time, the driven link 4 is provided with a sliding foot 12, and the sliding foot 12 is slidably connected in the track groove. The driving lead screw motor 9 drives the driving lead screw 10 to drive the lead screw driving rod 11 to perform a linear motion, and then drives the outward-opening spoiler assembly 3 to perform an angular flip through the driving slider 7 and the driving link 6. At the same time, the lead screw driving rod 11 drives the outward-opening spoiler assembly to move along the track groove of the guiding block 8 through the connecting rod 5 and the driven link 4, realizing the second-stage lifting.

[0038] As Figure 2 、 3 shown, during the second-stage lifting process, the main spoiler assembly 14 remains stationary, while the outward-opening spoiler assembly 3 continues to lift to the second lifting state.

[0039] Specifically, in one embodiment, the second-stage lifting mechanism assembly 16 is symmetrically arranged. The driving lead screw motor 9 and the driving lead screw 10 are arranged in the middle of the upper base assembly 1. Two sliding guide rails 2 are respectively arranged on both sides of the upper base assembly 1 along the length direction of the vehicle, and the two driving sliders 7 are respectively slidably arranged in the sliding guide rails 2. Both ends of the lead screw driving rod 11 are respectively connected to a driving slider 7. The driving link 6, the driven link 4, the connecting rod 5, and the guiding block 8 can all be symmetrically arranged. The shape of the track groove is configured to control the movement track of the outward-opening spoiler assembly 3, so that it generates a composite movement of moving upward and backward and angular flipping at the same time. Specifically, as Figure 6 、 7 shown, the overall shape of the track groove is a Z shape extending towards the rear of the vehicle. As Figure 6As shown, when the sliding foot 12 is located at the lowest end of the Z - shape, the two - stage lifting mechanism assembly is in the closed state. At this time, the one - stage lifting mechanism assembly may be in the closed or open state. As Figure 7 shown, when the sliding foot 12 is located at the topmost end of the Z - shape, the two - stage lifting mechanism assembly is in the fully open state. At this time, the one - stage lifting mechanism assembly may be in the open state. The sliding foot 12 slides in the track groove of the 8 guide blocks, and the driven connecting rod 4 makes displacements in the X - direction and Z - direction, driving the outward - opening spoiler assembly 3 to achieve the process of lifting backward and upward. To ensure the stability of the entire structure, reinforcing ribs fixed to the guide block 8 can be added.

[0040] The hinge point of the driving connecting rod 6 and the outward - opening spoiler assembly 3, as well as the connection point of the driven connecting rod 4 and the outward - opening spoiler assembly 3, are located at different positions of the outward - opening spoiler assembly 3 to form a moment for the outward - opening spoiler assembly 3 to flip. During the opening process of the outward - opening spoiler assembly 3, the role of the two - stage lifting mechanism assembly is to determine the opening angle of the outward - opening spoiler as the screw - rod driving motor 9 rotates. Among them, there is a certain proportional relationship between the driving connecting rod and the driven connecting rod. With the forward and reverse rotation and the number of rotation circles of the screw - rod driving motor 9 being different, there is a certain angular relationship between the driving connecting rod and the driven connecting rod, so that the included angle between the starting point and the ending point when the outward - opening spoiler assembly 3 makes a circular arc motion is different, and this angle also affects the final opening angle of the outward - opening spoiler.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not used to limit the implementation scope of the present invention. Any equivalent changes and modifications made within the protection scope of the present invention should be considered to fall within the protection scope of the present invention.
