[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0054] An automotive tail fin is usually a component installed at the rear end of an automobile. When the automobile is running, the tail fin acts on the air to generate pressure on the automobile, which can increase the adhesion of the vehicle to the ground, thereby improving the aerodynamic performance of the vehicle, reducing the wind resistance coefficient, and enhancing safety and stability.

[0055] According to the first aspect of the present application, a hinge assembly is provided, and this hinge assembly is at least used for the tail fin of a vehicle. Please refer to Figures 1 to 5The hinge assembly includes a first support 10, a first arm 20 and a second arm 30; wherein the first end of the first arm 20 is rotatably mounted on the first support 10 around a first rotating shaft 101, and the second end of the first arm 20 is rotatably mounted on the second arm 30 around a second rotating shaft 31, and the axes of the first rotating shaft 101 and the second rotating shaft 31 are at a set angle. It can be understood that the first support 10 is fixedly mounted on a certain carrier, for example, fixedly mounted on the body of a vehicle, and the body of the vehicle provides bearing capacity for the first support 10. The first arm 20 rotates around the first rotating shaft 101, and the first arm 20 and the second arm 30 are connected by the second rotating shaft 31, so that when the second rotating shaft 31 moves, it can drive the first arm 20 and the second arm 30 to move in linkage. The entire hinge assembly is mainly composed of the first arm 20 and the second arm 30, so that the hinge assembly has a small number of parts, a simple structure, and is easy to process, produce and assemble, and has high reliability. The angle between the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31 can be set to a variety of angles, and the angle is determined in the following manner: when the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31 do not intersect, the two axes are projected onto the same plane so that the axes of the two axes can reach the maximum acute angle on the projection plane, which is the angle between the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31; when the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31 intersect, the angle of their intersection is the angle between the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31. The axis of the first rotating shaft 101 and the axis of the second rotating shaft 31 is at a set angle, and the angle should not be zero. During implementation, the movement mode of the second support arm 30 can be adjusted by adjusting the angle between the axis of the first rotating shaft 101 and the axis of the second rotating shaft 31.

[0056] It should be noted that the axes of the first rotating shaft 101 and the second rotating shaft 31 are at a set angle, that is, the axes of the first rotating shaft 101 and the second rotating shaft 31 are not arranged in parallel, so that when the first arm 20 rotates around the first rotating shaft 101, the first arm 20 moves away from one end of the first support 10, that is, the second rotating shaft 31 rotates in a manner of one end being high and the other end being low, that is, during the rotation process, one end of the second rotating shaft 31 is closer to the first support 10, and the other end of the second rotating shaft 31 is farther from the first support 10. The second arm 30 has a rotating end rotatably connected to the first arm 20, and a supporting end that plays a supporting role. When the first arm 20 rotates around the first rotating shaft 101, the rotating end of the second arm 30 is also displaced. The supporting end of the second arm 30 can be restricted to move according to a preset trajectory or when its moving distance is small, the supporting end of the second arm 30 mainly plays a supporting role, and the second arm 30 is in a posture with one end high and the other end low. In other words, as Figure 1In it, the second arm 30 moves forward and tilts, with the end close to the first support 10 being higher and the end far from the first support 10 being lower, that is, in a posture with the left side higher and the right side lower. In addition, the hinge assembly is driven by driving the first arm 20 and / or the second arm 30, so that the hinge assembly structure for moving the second rotating shaft 31 is simple. Combining with the vehicle coordinate system, the vehicle coordinate system has +X in the horizontal direction towards the rear of the vehicle, +Z in the longitudinal upward direction, and +Y in the horizontal direction towards the right side of the driver. By installing the vehicle spoiler through this hinge assembly, the vehicle spoiler can have a posture of tilting towards the front of the vehicle in the X direction of the vehicle coordinate system and having one end higher and one end lower in the Y direction of the vehicle coordinate system. Generally, the spoiler near the front of the vehicle is set lower, the spoiler far from the front of the vehicle is set higher, the spoiler near the middle of the vehicle is set lower, and the spoiler near the periphery of the vehicle is set higher.

[0057] In some embodiments, please refer to Figure 1 、 Figure 2 and Figure 4 , a first support rod 33 is provided on the second arm 30, and a support structure 40 is connected to the end of the first support rod 33, and the support structure 40 enables the end of the first support rod 33 to move along a preset path. It can be understood that the first support rod 33 is provided on the second arm 30 to support the first support rod 33 through the support structure 40, so that the second arm 30 has a stable movement path or moves along a preset movement path. Exemplarily, the connection end of the first support rod 33 and the support structure 40 can only move along an arc-shaped trajectory. In addition, the connection end of the first support rod 33 and the support structure 40 can also be set to other shaped movement trajectories, which need to be determined according to the set purpose.

[0058] In one embodiment, the first bearing portion 32 and the first support rod 33 can be provided on the same side of the second arm 30 where the second rotating shaft 31 is located. Generally, the first bearing portion 32 and the first support rod 33 are respectively provided on both sides of the second rotating shaft 31 on the second arm 30, that is, both the first bearing portion 32 and the first support rod 33 are provided on the second arm 30, but on both sides of the axis of the second rotating shaft 31 to facilitate providing appropriate bearing capacity through the second rotating shaft 31. In addition, the second arm 30 has a certain thickness. For example, the second arm 30 is generally H-shaped, and the first support rod 33 can be provided on any side where the end of the second rotating shaft 31 intersects with the second arm 30. The second arm 30 includes a first rod 35, a second rod 36, and a third rod 37. The second rod 36 is connected between the first rod 35 and the third rod 37, and the first rod 35 and the third rod 37 are substantially parallel to form the H shape of the second arm 30. Please refer to Figure 2 , that is, the first support rod 33 is arranged to extend from the second arm 30 in the -X or +X direction of the vehicle coordinate system. Both settings are acceptable. In the two implementation manners, the supporting force and movement trajectory provided by the support structure 40 are opposite.

[0059] In some embodiments, refer to Figure 1 and Figure 2 , the supporting structure 40 includes a second strut 41 connected to the end of the first strut 33 in a spherical pair manner, and the second strut 41 is arranged to move along an arc trajectory. It can be understood that the second strut 41 is connected to the first strut 33 in a spherical pair manner, so that when the second rotating shaft 31 moves, the second strut 41 and the first strut 33 can relatively move in a spherical pair manner, providing a moving space for the movement of the second rotating shaft 31. By arranging the second strut 41 to move along an arc trajectory, the movement of the second rotating shaft 31 is restricted to move along the set trajectory. The first strut 33 is provided with a ball head mounting seat 130, and the second strut 41 is provided with a guiding ball head 140. The ball head mounting seat 130 and the guiding ball head 140 are connected in a spherical pair manner. During assembly, the guiding ball head 140 is inserted into the ball head mounting seat 130 from the -Z direction to complete the installation.

[0060] In some embodiments, refer to Figure 1 and Figure 2 and Figure 4 , the second strut 41 is installed at one end of a third strut 42, the other end of the third strut 42 is installed on a third rotating shaft 43, and the third rotating shaft 43 is installed on a second support 50. It can be understood that the second strut 41 is supported by the third strut 42, and then the third strut 42 is installed on the third rotating shaft 43, so that the second strut 41 can be limited to move along a circular arc trajectory around the third rotating shaft 43. When the axis of the third rotating shaft 43 is parallel to the X direction, the second strut 41 moves in the plane formed by X-Z. Among them, the moving radius of the circular arc trajectory of the second strut 41 around the third rotating shaft 43 depends on the length of the third strut 42 and the installation angle between the third strut 42 and the third rotating shaft 43. Usually, the third strut 42 is set in an L shape, with one end connected between the second strut 41 and the third rotating shaft 43. While facilitating installation, it reduces the interference with other components when the second strut 41 rotates, for example, avoiding the movement interference between the first strut 33 and the third rotating shaft 43. The third rotating shaft 43 is installed on the second support 50 and is carried by the second support 50, and the second support 50 is fixedly installed on the vehicle body.

[0061] In some embodiments, refer to Figure 1 and Figure 2, the second arm 30 has a first end and a second end intersecting with the second rotating shaft 31. The distance between the first end of the second arm 30 and the first rotating shaft 101 is less than the distance between the second end of the second arm 30 and the first rotating shaft 101. The first rod 33 is disposed on the side where the first end of the second arm 30 is located. It can be understood that since the axes of the first rotating shaft 101 and the second rotating shaft 31 are arranged at an angle, the distances between the two ends of the second arm 30 and the first rotating shaft 101 are different. By disposing the first rod 33 on the side where the first end of the second arm 30 is located, when the second arm 30 is driven, the moving distance of the first rod 33 is shorter, which is beneficial to installing the structure for supporting the first rod 33 and reduces the space occupation. When the first rod 33 is installed, it is arranged at an angle with the installation surface of the second arm 30, making the installation method of the first rod 33 more flexible.

[0062] In some embodiments, please refer to Figure 1 and Figure 2 , the first rod 33 is installed along the axial direction of the second rotating shaft 31. It can be understood that the first rod 33 extends along the axial direction of the second rotating shaft 31, that is, the first rod 33 extends approximately parallel to the axial direction of the second rotating shaft 31, which is convenient for installing the supporting structure 40 cooperating with the first rod 33. In addition, the axis of the first rod 33 can also be installed coinciding with the axial direction of the second rotating shaft 31 to provide a flexible setting method for the first rod 33.

[0063] In some embodiments, please refer to Figure 1 and Figure 2 , a first bearing portion 32 for bearing a load is provided on the second arm 30. Through this first bearing portion 32, a specific component is borne. Exemplarily, the specific component is the tail wing of a vehicle. It can be understood that the first bearing portion 32 is used to bear the tail wing of the vehicle, and the tail wing is fixedly installed on the first bearing portion 32. The first bearing portion 32 can be provided in various shapes, such as rod-shaped or plate-shaped, etc. The number of the first bearing portions 32 can be multiple, such as 1 - 4, so as to firmly install the tail wing of the vehicle on the first bearing portion 32. In addition, the tail wing can also be directly installed on the second arm 30, and a similar effect of controlling the movement of the tail wing can also be achieved.

[0064] In some embodiments, please refer to Figure 1 and Figure 2 , the plane where the second arm 30 and the axis of the second rotating shaft 31 are located is the first plane, and the first bearing portion 32 is arranged at an angle with the first plane. It can be understood that the plane formed by the second arm 30 and the axis of the second rotating shaft 31 is the first plane, and the first plane is Figure 2When in the initial position, it is generally the plane formed by the coordinate axes X - Y. The first bearing part 32 is arranged at an angle with the first plane, that is, this angle is not zero, and it can usually be set to 60° to 90°, so that the first bearing part 32, the second arm 30 and the second rotating shaft 31 are not coplanar, which is convenient for installing the object to be carried on the first bearing part 32, that is, convenient for installing the tail wing. Usually, the first bearing part 32 is arranged perpendicular to or nearly perpendicular to the plane formed by the axis of the second arm 30 and the second rotating shaft 31. For example, when the hinge assembly is in the initial position, in the vehicle coordinate system, the first plane is set as a substantially horizontal plane, the first bearing part 32 is arranged substantially along the +Z direction of the coordinate system, and is arranged above the second arm 30 to facilitate the installation of the tail wing. Usually, the second arm 30 has a certain thickness in the Z direction of the coordinate system. The determination method of the first plane where the axis of the second rotating shaft 31 is located is that this plane passes through the axis of the second rotating shaft 31, that is, the axis of the second rotating shaft 31 is located in this plane, and this plane divides or substantially divides the second arm 30 evenly along the thickness direction of the second arm 30.

[0065] In some embodiments, please refer to Figure 1 and Figure 2 , the second arm 30 has a first end and a second end intersecting with the second rotating shaft 31. The distance between the first end of the second arm 30 and the first rotating shaft 101 is less than the distance between the second end of the second arm 30 and the first rotating shaft 101. The first bearing part 32 is arranged on the side where the second end of the second arm 30 is located.. It can be understood that since the axes of the first rotating shaft 101 and the second rotating shaft 31 are arranged at an angle, the distances between the end parts on both sides of the first rotating shaft 101 and the second rotating shaft 31 are different, one side end part is farther, and the end part on the other side is closer. The first bearing part 32 is arranged on the side where the second end of the second arm 30 is located, so that when the second arm 30 is driven, the first bearing part 32 can move in the +Z direction of the vehicle coordinate system, and the moving distance is larger, so that the tail wing installed on the first bearing part 32 can rise.

[0066] In some embodiments, please refer to Figure 1 and Figure 2 , the first arm 20 and the first support 10 are connected in the form of a cylindrical pair. It can be understood that the first arm 20 and the first support 10 are connected in the form of a cylindrical pair through the first rotating shaft 101, so that the first arm 20 can rotate along the first rotating shaft 101 and can also move along the axis of the first rotating shaft 101. When installing and manufacturing the hinge assembly, certain manufacturing and installation errors are allowed to exist, the precision requirements are reduced, and the jamming phenomenon of the hinge assembly is avoided.

[0067] In some embodiments, please refer to Figure 1 and Figure 2, the first arm 20 and the second arm 30 are connected in the form of a cylindrical pair. It can be understood that the first arm 20 is connected to the second arm 30 in the form of a cylindrical pair through the second rotating shaft 31, so that the first arm 20 and the second arm 30 can rotate relative to each other along the second rotating shaft 31 and can move along the axis of the second rotating shaft 31. When installing and manufacturing the hinge assembly, certain manufacturing and installation errors are allowed to exist, the precision requirements are reduced, and the jamming phenomenon of the hinge assembly is avoided.

[0068] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 , at least one telescopic member is provided on the first arm 20 and / or the second arm 30 for controlling the first arm 20 and / or the second arm 30 to complete a preset action. It can be understood that the first arm 20 and the second arm 30 need to be driven by an external force to move. An external force is generated by the telescopic member to drive the first arm 20 and / or the second arm 30 to complete a preset action. Among them, the telescopic member can be two or three, which are set according to needs. The telescopic member includes an electric or pneumatic telescopic member, such as a controllable electric spring or a pneumatic spring. The telescopic member can also be set in the form of a balance spring. In one embodiment, there are two telescopic members. One end of each telescopic member is installed on the second arm 30, and the other end is installed on the vehicle body. There are various installation methods for the second arm 30 and the telescopic member. One method is that a ball joint seat 120 is provided on the second arm 30, and the telescopic member is provided with a ball joint matching the ball joint seat 120 to facilitate the installation of the telescopic member. The two ball joint seats 120 are respectively installed on both sides of the axis of the second rotating shaft 31 and have a certain distance. One telescopic member is controlled to extend and the other is shortened to more easily drive the hinge assembly to complete a specific action.

[0069] In some embodiments, refer to Figure 1 , Figure 2 , the axes of the first rotating shaft 101 and the second rotating shaft 31 intersect at a point. It can be understood that the first rotating shaft 101 and the second rotating shaft 31 are arranged in the same plane and intersect at a point. Such a setting makes the hinge assembly easier to be driven and does not jam.

[0070] In some embodiments, refer to Figure 1 , Figure 2 and Figure 5, further comprising a second bearing portion 60, the second bearing portion 60 is connected to the fourth strut 70 in a spherical pair manner, and the fourth strut 70 is configured to move within a set plane. It can be understood that by restricting the movement of the fourth strut 70, the fourth strut 70 provides a supporting effect on the second bearing portion 60, enabling the second bearing portion 60 to provide a supporting force. The second bearing portion 60 is used to install the tail wing. Therefore, through this structure, the installation of the tail wing can be made more stable, and the second bearing portion 60 can effectively limit the movement range of the tail wing installed thereon. In addition, a guiding ball head 140 is provided on the second bearing portion 60, and a ball head mounting seat 130 is provided on the fourth strut 70. During assembly, the guiding ball head 140 is inserted into the ball head mounting seat 130 from the +Z direction to complete the installation. It should be noted that the fourth strut 70 moves within a set plane. When the set plane is moved, the fourth strut 70 also moves accordingly. In addition, the fourth strut 70 can also be set to rotate within an appropriate range along its own axis and prohibited from rotating.

[0071] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 , the fourth strut 70 is mounted on the fifth strut 80 in a planar pair manner, enabling the fifth strut 80 to play a bearing role on the fourth strut 70. The fourth strut 70 is mounted on the fifth strut 80 in a planar pair manner, causing the second bearing portion 60 mounted thereon to also move in a planar pair. In addition, the fifth strut 80 is rotatably mounted on the third support 90, and the third support 90 supports the fifth strut 80, and the mounting position of the fifth strut 80 can be adjusted within an appropriate range. Usually, the third support 90 is mounted on the vehicle body and is mounted along the Z direction of the vehicle coordinate system, that is, roughly longitudinally. The mounting direction of the fifth strut 80 can rotate around the mounting point of the third support 90 to adjust the inclination of the fifth strut 80. Usually, the fifth strut 80 is mounted along the X direction. It should be noted that the planar pair movement of the fourth strut 70 is relative to the fifth strut 80. When the fifth strut 80 is moved, the planar pair where the fourth strut 70 is located also follows the fifth strut 80 to move, and the relative planar pair movement of the fourth strut 70 with respect to the fifth strut 80 remains unchanged. Therefore, the fifth strut 80 is usually set in a form fixed relative to the vehicle body, and the inclination of the fifth strut 80 is adjusted only when adjusting the inclination angle of the tail wing on the installer. Usually, the plane where the fourth strut 70 is located does not change.

[0072] According to the second aspect of the present application, a vehicle tail wing is provided, including the aforementioned hinge assembly. Since the vehicle tail wing has the aforementioned hinge assembly, it also has all the beneficial effects of the aforementioned hinge assembly. Please refer to Figure 1 , Figures 3 to 5, wherein a first tail wing plate 100 is mounted on the first bearing portion 32. When the tail wing is not opened, it is set to an initial position. In the initial position, the first tail wing plate 100 is set to be approximately horizontal with the first plane. When the tail wing is opened, the second arm 30 is driven to move by power, and the first arm 20 rotates and slides around the axis of the first rotating shaft 101, wherein the sliding of the first arm 20 makes the rotation of the hinge assembly smoother due to assembly errors, etc. The first support rod 33 and the second support rod 41 on the second support arm 30 rotate in a spherical pair, and the connection position between the second support rod 41 and the first support rod 33 is restricted by the supporting structure 40 to a circular arc movement, which plays a role in guiding the motion trajectory, thereby enabling the tail wing to first open sideways and then rotate upward. When the tail wing is closed, the action is opposite to the above-mentioned tail wing opening action.

[0073] In some embodiments, the hinge assembly includes a second bearing portion 60, which is connected to a fourth support rod 70 in a spherical pair, and the fourth support rod 70 is configured to move at least within a set plane; a first tail wing panel 100 is mounted on the second bearing portion 60.
