Detailed Description of the Embodiment

[0042] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0043] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0044] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0045] In the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited.

[0046] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0048] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements are only drawn by way of example in the drawings and not necessarily to the actual scale.

[0049] To facilitate the understanding of the technical solution of the present application, before elaborating in detail, the tail fins in the related art will be described first.

[0050] When the vehicle is traveling at a relatively high speed, due to the influence of wind resistance, lift will be generated under the vehicle body, resulting in a decrease in the tire grip of the vehicle and a decrease in the stability of the vehicle. Therefore, in order to reduce wind resistance and improve the stability of the vehicle body, a retractable tail fin is generally designed at the rear of the vehicle. When the vehicle is traveling at a high speed, the tail fin can be deployed to optimize the lift and air resistance during the vehicle's travel, increase the vehicle's downforce, and improve the stability of the vehicle at high speed. When traveling at a low speed, the upward force of the vehicle is not obvious, but the downforce borne by the tail fin will cause the vehicle to require more power to overcome wind resistance and increase fuel consumption. Therefore, the tail fin needs to be retracted when traveling at a low speed.

[0051] The inventor has found through research that by adjusting the angle when the tail fin is raised, the wind resistance can be further reduced. However, the devices in the related art that can adjust the angle of the tail fin often rely on a relatively complex structure, such as a crank connecting rod structure. Such a transmission method not only makes the transmission efficiency between the structures low, but also is extremely prone to failure.

[0052] Based on this, the inventor has improved the structure of the adjusting device and realized the angle adjustment by means of a simple guide rail, so that the adjusting device can more easily adapt to the angle requirements in different states. For the convenience of description, the drawings only show the structures related to the embodiments of the present application.

[0053] Figure 1 Shows a schematic diagram of the adjusting device 100 in the present application in a retracted state; Figure 2 Shows a schematic diagram of the adjusting device 100 in the present application in an unfolded state.

[0054] Refer to Figure 1 and in combination with Figure 2, an adjustment device 100 provided in an embodiment of the present application includes a base 110, a mounting member 120, a lifting mechanism 130, and an adjustment mechanism 140. The base 110 has a receiving space A, and the mounting member 120 is movably connected to the base 110. The lifting mechanism 130 is disposed between the base 110 and the mounting member 120, and the lifting mechanism 130 is configured to be able to drive the mounting member 120 to lift along a preset direction Z1, so that the mounting member 120 can be switched between a deployed state and a retracted state. The adjustment mechanism 140 is disposed on the base 110, and the mounting member 120 is rotatably connected to the adjustment mechanism 140 about a rotation axis R. Among them, when the mounting member 120 is in the retracted state, the mounting member 120 is received in the receiving space A, and when the mounting member 120 is in the deployed state, the adjustment mechanism 140 is configured to be able to adjust the mounting member 120, so that the mounting member 120 rotates a preset angle around the rotation axis R.

[0055] In the adjustment device 100 provided in the present application, the mounting member 120 is lifted relative to the base 110 by means of the lifting mechanism 130 to adjust the position of the mounting member 120 in the height direction Z2, so that the mounting member 120 can be switched between a deployed state and a retracted state. Among them, the height direction Z2 is arranged at an angle with the preset direction Z1. In the retracted state, the mounting member 120 can be received in the receiving space A, realizing the lowering of the mounting member 120, and can minimize the space occupied by the adjustment device 100 in the height direction Z2. When the mounting member 120 is in the deployed state, it can rotate a preset angle by means of the adjustment mechanism 140, so as to meet the angle requirements of the mounting member 120 in the deployed state.

[0056] Please continue to refer to Figure 1 and Figure 2 , in some embodiments, the adjustment mechanism 140 includes an adjustment seat 141 and a guide rail 142 disposed on the adjustment seat 141. The mounting member 120 is rotatably disposed on the guide rail 142 and is slidably connected to the guide rail 142. Among them, there is an included angle between the direction from the starting end of the guide rail 142 to the ending end of the guide rail 142 and the preset direction Z1. It can be understood that the starting end of the guide rail 142 refers to the end closer to the base 110 among the two opposite ends of the guide rail 142, and the ending end of the guide rail 142 refers to the end far from the base 110. When the mounting member 120 is switched from the retracted state to the deployed state by means of the lifting mechanism 130, it slides from the starting end of the guide rail 142 to the ending end of the guide rail 142. There is an included angle between the direction from the starting end of the guide rail 142 to the ending end of the guide rail 142 and the preset direction Z1, that is, there is a height difference between the ending end of the guide rail 142 and the preset direction Z1. When the mounting member 120 slides to the ending end of the guide rail 142, due to the guidance of the guide rail 142 and its own weight, the side of the mounting member 120 connected to the guide rail 142 has a tendency to move downward. In this way, the mounting member 120 can be rotated to achieve adjustment to a preset angle.

[0057] Figure 3 The figure shows a schematic diagram during the movement of the adjusting device 100 according to an embodiment of the present application.

[0058] As Figure 3 shown, and in combination with Figure 1 and Figure 2 , in some embodiments, the guide rail 142 includes a guiding portion 142a and a bending portion 142b connected to each other. The extending direction of the guiding portion 142a is parallel to the preset direction Z1, and the bending portion 142b is arranged at an angle with the guiding portion 142a. In this way, the guiding portion 142a can provide support and guidance for the lifting of the mounting member 120 in the preset direction Z1. During the sliding process of the mounting member 120 on the guiding portion 142a, as Figure 3 shown, the mounting member 120 does not undergo angle adjustment. The bending portion 142b arranged at an angle with the guiding portion 142a enables the mounting member 120 to complete a rotation action by means of the bending portion 142b, and further complete the adjustment of a preset angle, that is, the mounting member 120 in the unfolded state as Figure 2 shown. Specifically, in some embodiments, the guide rail 142 further includes an arc portion 142c, and the arc portion 142c is smoothly connected between the guiding portion 142a and the bending portion 142b. In this way, the rotation action of the mounting member 120 can be made smoother through the arc portion 142c, improving the visual effect when the mounting member 120 rotates.

[0059] As Figures 1 to 3 shown, in some embodiments, rollers 150 are provided on the mounting member 120, and the rollers 150 are configured to be able to move along the guide rail 142. In this way, the rollers 150 can convert the sliding friction between the mounting member 120 and the guide rail 142 into rolling friction, thereby reducing the frictional force. This can not only make the lifting and angle adjustment of the mounting member 120 smoother, but also extend the service life of the adjusting device 100.

[0060] Please continue to refer to Figures 1 to 3In some embodiments, the mounting member 120 includes a mounting portion 121 and a connecting portion 122 connected to each other and arranged at an angle. In combination with some embodiments described later, the mounting portion 121 is used to mount the spoiler 200. The roller 150 is arranged at one end of the connecting portion 122 away from the mounting portion 121. In this way, the ease of adaptation of the roller 150 and the guide rail 142 can be improved by means of the connecting portion 122. Specifically, in some embodiments, the adjustment seat 141 is provided in two, the two adjustment seats 141 are arranged at intervals from each other, and the two guide rails 142 on the two adjustment seats 141 are parallel to each other. The roller 150 is provided in two, and the two rollers 150 are respectively installed on the opposite sides of the connecting portion 122. Each roller 150 is arranged corresponding to a guide rail 142. In this way, the two guide rails 142 and the two rollers 150 can better provide support for the mounting member 120, so that the mounting member 120 can maintain better stability during movement.

[0061] like Figures 1 to 3 As shown, in some embodiments, the lifting mechanism 130 includes a crank connecting rod structure 131 and a driving member 132. The crank connecting rod structure 131 is transmission-connected between the driving member 132 and the mounting member 120, so that the mounting member 120 can be lifted and lowered along the preset direction Z1 in response to the driving force of the driving member 132. In this way, the driving force of the driving member 132 can be reliably converted into a force that drives the mounting member 120 to be lifted and lowered along the preset direction Z1 by means of the crank connecting rod structure 131. Exemplarily, the driving member 132 can be a motor. Further, the lifting mechanism 130 also includes a transmission shaft 133, which is transmission-connected between the motor and the crank connecting rod structure 131. In this way, the driving force of the driving member 132 can be transmitted to the crank connecting rod structure 131 by means of the transmission shaft 133.

[0062] Figure 4 A schematic diagram showing an adjusting device 100 according to another embodiment of the present application in an unfolded state is shown.

[0063] like Figure 4As shown, in some embodiments, the crank - connecting rod structure 131 includes a crank 131a and a connecting rod 131b. The crank 131a is in transmission connection with the driving member 132 and is rotatably connected to the base 110. The connecting rod 131b is rotatably connected between the crank 131a and the mounting member 120. Wherein, the crank 131a includes a crank body p and a limiting portion q connected to the crank body p. When the mounting member 120 is in the unfolded state, at least part of the limiting portion q can abut against the base 110 so that the crank - connecting rod structure 131 is self - locked. Combining with the foregoing some embodiments, the crank 131a is connected to the transmission shaft 133. The driving force of the driving member 132 drives the transmission shaft 133 to rotate, so that the crank 131a rotates, and then drives the connecting rod 131b to rotate to lift the mounting member 120. Thus, when the mounting member 120 is in the unfolded state, by means of the abutment between the limiting portion q and the base 110, the movement of the crank - connecting rod structure 131 can be restricted, thereby realizing the self - locking of the crank - connecting rod structure 131. Moreover, the limiting portion q can also provide a supporting force for the mounting member 120, so that the mounting member 120 can be more stably maintained in the unfolded state. Specifically, in some embodiments, at least part of the limiting portion q is configured as a plane to maintain surface contact with the base 110 when abutting against the base 110. In this way, the support of the limiting portion q can be more stable through the surface - contact abutment method.

[0064] In some embodiments, the adjusting device 100 further includes a guide member 160. One end of the guide member 160 is connected to the base 110, and the other end is rotatably connected to the mounting member 120, and the guide member 160 is configured to be able to expand and contract along a preset direction Z1. Thus, with the help of the guide member 160, the lifting direction of the mounting member 120 can be guided to avoid the deviation of the lifting direction of the mounting member 120. When the guide member 160 expands and contracts to guide the mounting member 120 to switch between the storage state and the unfolded state, the mounting member 120 rotates relative to the guide member 160, and the adjusting mechanism 140 can adjust the angle of the mounting member 120.

[0065] Figure 5 Fig. shows a schematic diagram of the tail - fin device 1000 according to an embodiment of the present application in the storage state; Figure 6 Fig. shows a schematic diagram of the tail - fin device 1000 according to an embodiment of the present application in the unfolded state.

[0066] Based on the same inventive concept, combining Figure 5 and Figure 6As shown in the figure, the present application also provides a wing device 1000, which includes the above-mentioned adjusting device 100 and spoiler 200, and the spoiler 200 is installed on the mounting member 120. Among them, when the mounting member 120 is in the unfolded state, the spoiler 200 is configured to be able to rotate a preset angle following the mounting member. In this way, by means of the rotation of the mounting member 120, the spoiler 200 can rotate a preset angle accordingly, thereby adjusting the angle of the spoiler 200 so that it can minimize the wind resistance to the greatest extent in the unfolded state.

[0067] In some embodiments, a plurality of adjusting devices 100 are provided, and the plurality of adjusting devices 100 are arranged at intervals along the longitudinal length of the spoiler 200. In this way, the plurality of adjusting devices 100 can adjust the lifting and angle of the spoiler 200 from multiple positions. Specifically, in the embodiment shown in Figure 5 and Figure 6 the figure, two adjusting devices 100 are provided.

[0068] Based on the same inventive concept, the present application also provides a vehicle, which includes the above-mentioned wing device 1000. For a vehicle using the above-mentioned wing device 1000, when the vehicle is traveling at a high speed, the spoiler 200 in the wing device 1000 rises to unfold and is inclined at an angle, which can better reduce the influence of wind resistance, improve the grip of the vehicle, and enhance the stability of the vehicle when traveling at a high speed. When the vehicle is traveling at a low speed, the spoiler 200 in the wing device 1000 descends to be stored, reducing the fuel consumption of the vehicle when traveling at a low speed.

[0069] Combined with Figures 1 to 6As shown in the figure, the adjustment device 100 provided by the embodiment of the present application includes at least a base 110, a mounting member 120, a lifting mechanism 130, and an adjustment mechanism 140. The mounting member 120 is lifted relative to the base 110 by means of the lifting mechanism 130 to adjust the position of the mounting member 120 in the height direction Z2, so that the mounting member 120 can be switched between the deployed state and the retracted state. In the retracted state, the mounting member 120 can be received in the accommodation space A to realize the lowering of the mounting member 120. When the mounting member 120 is in the deployed state, it can be rotated by a preset angle by means of the adjustment mechanism 140, so as to meet the angle requirements of the mounting member 120 in the deployed state. The guide rail 142 in the adjustment mechanism 140 can guide the mounting member 120 to rotate around the rotation axis R, so as to adjust to the preset angle. The guiding portion 142a in the guide rail 142 is parallel to the preset direction Z1, and can provide support and guidance for the lifting of the mounting member 120 in the preset direction Z1. The bending portion 142b can guide the mounting member 120 to rotate to adjust the angle. The arc portion 142c connected between the bending portion 142b and the guiding portion 142a can make the rotation action of the mounting member 120 smoother and improve the visual effect when the mounting member 120 rotates. The roller 150 provided on the mounting member 120 can convert the sliding friction between the mounting member 120 and the guide rail 142 into rolling friction, thereby reducing the friction force. The crank 131a in the crank-link structure 131 includes a crank body p and a limiting portion q connected to the crank body p. By abutting against the base 110 with the limiting portion q, the self-locking of the crank-link structure 131 can be realized, and further the mounting member 120 can be locked in the deployed state. The telescopic guide member 160 can guide the lifting direction of the mounting member 120 to prevent the lifting direction of the mounting member 120 from deviating. For the spoiler device 1000 provided by the present application, by using the above adjustment device 100, the angle of the spoiler 200 can be adjusted more easily. For a vehicle using the above spoiler device 1000, the angle of the spoiler 200 can be adjusted more easily according to needs, so as to adapt to different requirements.

[0070] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0071] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
