Description

Technical Field

[0001] The present disclosure relates to a pre-positioning device and an air turbulence device. Background Art

[0002] With the increasingly widespread application of automobile lightweight technology, the weight of the entire vehicle is getting lighter and lighter, resulting in insufficient grip when the vehicle is driving at high speed, which reduces the controllability of the entire vehicle. In severe cases, it may cause the vehicle to lose control and cause a traffic accident.

[0003] To this end, electric rear spoiler systems, which automatically adjust their position based on vehicle speed, are becoming increasingly common. At low speeds, the spoiler retracts to reduce wind resistance and improve fuel and power consumption. As speed increases, the spoiler gradually rises, improving aerodynamics, maneuverability, and safety at high speeds.

[0004] However, when assembling a vehicle, workers are required to fix the spoiler to the vehicle body with screws. When actually installing these screws, the screw installation positions cannot be effectively aligned, resulting in low installation efficiency. Utility Model Content

[0036] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0037] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0038] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0039] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings.

[0041] Figure 1 It is a schematic structural diagram of an air spoiler according to one embodiment of the present disclosure. Figure 2 and Figure 3 yes Figure 1 A magnified schematic diagram of part A in FIG.

[0042] like Figures 1 to 3As shown, the present disclosure provides an air spoiler device, which includes components such as a tail wing 100, a driving device 200, an execution device 300 and a base 400.

[0043] When a vehicle equipped with an air spoiler is driving, the position of the rear wing 100 can be adjusted so that the distance and angle between the rear wing and the outer surface of the vehicle are different. As a result, when air flows over the upper and lower surfaces of the rear wing 100, the friction between the vehicle and the road surface can be increased or reduced. Accordingly, when the vehicle speed is high, the increased friction can make the vehicle more stable, and when the vehicle speed is low, the reduced friction can make the vehicle more fuel-efficient or more energy-efficient.

[0044] The driving device 200 includes a driving shaft 201 , through which the driving device 200 outputs a driving action, and an actuator 300 , which can transmit the driving action output by the driving device 200 to the empennage 100 , so that the empennage 100 performs the first action or the second action.

[0045] In the present disclosure, the actuator 300 may be a multi-link structure, whereby the rotation output by the drive shaft 201 can cause the posture of the tail 100 to change. For the structure of the actuator 300, please refer to the contents described in CN215706723U, which will not be described in detail here.

[0046] The driving device 200 can be arranged on a base 400 , and accordingly, the base 400 can be fixed on the vehicle body, thereby fixing the entire air spoiler device on the vehicle body.

[0047] In a preferred embodiment, a pre-positioning device 900 is further provided on the base 400 , that is, the pre-positioning device 900 is installed on the base 400 and can achieve pre-positioning between the base 400 and the vehicle body.

[0048] The pre-positioning device 900 may include a central column 910 and an external fixing portion 920. One end of the central column 910 is fixed to the base 400, and the other end of the central column 910 is disposed away from the base 400.

[0049] In the present disclosure, the central column 910 can be formed into a cylindrical shape, one end of which can be fixed to the base 400 by welding. Of course, the central column 910 can also be fixed to the base 400 by a fixing member. In another embodiment, the central column 910 can be integrally formed with the base 400.

[0050] The outer fixing portion 920 is sleeved on the central column portion 910 , and the outer fixing portion 920 includes at least one fin 921 . At least a portion of the fin 921 is away from the central column portion 910 along a direction approaching the base 400 .

[0051] Therefore, when the pre-positioning device 900 of the present invention is in use, a corresponding mounting hole will be opened on the vehicle body, the central column portion 910 and the outer fixing portion 920 can be inserted into the mounting hole, and the fin 921 is in elastic contact with the inner wall surface of the mounting hole, that is, the aperture of the mounting hole is set to enable the fin 902 to produce elastic deformation, thereby preliminarily fixing the base 400 to the vehicle body.

[0052] Furthermore, after the base 400 is initially positioned, the base 400 is fixed to the vehicle body through connectors provided at other positions of the base 400 .

[0053] In a specific embodiment, the external fixing portion 920 is cylindrical with one end open, and the open end of the external fixing portion 920 is positioned adjacent to the base 400. More preferably, the other end of the external fixing portion 920 is secured to the central column 910 via a screw. In a specific embodiment, a through hole may be formed at the other end of the external fixing portion 920, and a threaded hole may be formed in the central column 910. A screw may pass through the through hole and be screwed into the threaded hole, thereby securing the external fixing portion 920 to the central column 910.

[0054] In the present disclosure, the central column portion 910 may be a cylinder, or a prism, and is preferably a cylinder. Thus, the outer peripheral surface of the central column portion 910 is formed as an outer cylindrical surface.

[0055] At this time, the inner surface of the outer fixing part 920 is also formed as a cylindrical surface, and the inner surface of the outer fixing part 920 is tightly arranged to the outer peripheral surface (outer cylindrical surface) of the central column part 910, thereby preventing shaking between the outer fixing part 920 and the central column part 910, thereby improving the pre-positioning accuracy of the base 400.

[0056] In a specific embodiment, Figure 2 and Figure 3 As shown, a plurality of grooves 922 are formed on the outer fixing portion 920 , and the grooves 922 extend from the opening of the outer fixing portion 920 to the other end of the outer fixing portion 920 , wherein the portion between two grooves 922 forms the above-mentioned fin 921 .

[0057] More preferably, the outer fixing portion 920 includes an axial direction, and the groove 922 is provided along the axial direction of the outer fixing portion 920 , thereby the fins 921 have substantially the same size (width) along the circumference of the outer fixing portion 920 .

[0058] There is a predetermined distance between the other end of the groove 922 and the other end of the external fixing portion 920. In other words, the groove 922 does not penetrate the external fixing portion 920, thereby ensuring that the external fixing portion 920 has a predetermined strength. Except for the deformation of the fin 921, other parts of the external fixing portion 920 will not be significantly deformed.

[0059] In a preferred embodiment, the fin 921 includes a first part 921A and a second part 921B connected to each other, wherein the first part 921A is close to the other end of the external fixing portion 920, and there is a preset angle between the first part 921A and the second part 921B, thereby, the second part 921B can be formed into an outward diverging state, and accordingly, elastic deformation can be generated at the connection between the first part 921A and the second part 921B.

[0060] More preferably, the first portion 921A is arranged along the axial direction of the outer fixing portion 920, and the second portion 921B forms an angle greater than 90° with the axial direction of the outer fixing portion 920. Preferably, the angle can be about 150°.

[0061] In a preferred embodiment, the fins 921 can be provided in a plurality, such as 2, 3, or 4. When there are multiple fins 921, the fins 921 are evenly distributed in the circumferential direction of the outer fixing portion 920 so that the deformation amounts of the fins 921 are substantially the same, thereby enabling the axis of the central column portion 910 to substantially coincide with the axis of the mounting hole.

[0062] In the present disclosure, at least two pre-positioning devices are provided on the base 400 . When two pre-positioning devices are provided, they are located at both ends of the base 400 in the length direction.

[0063] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.

In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.
