Description

[0002] The spoiler device, such as an automobile spoiler, mainly utilizes the pressure difference between the upper and lower surfaces when air passes through to generate downward pressure, and utilizes the downward pressure to enhance the grip of the vehicle, such as the tail, thereby avoiding excessive turning of the vehicle and enhancing the stability of the vehicle during high-speed driving. However, when the vehicle is driving at low speed, the spoiler device may increase the resistance of the vehicle, resulting in increased energy consumption.

[0035] As Figures 1 to 8 shown, the embodiment of the present application provides a spoiler device, which comprises a lifting frame 100, a pull rod 200, a driving mechanism 300, a limiting mechanism 400 and a spoiler 600;

[0036] The upper end of the lifting frame 100 is hinged to the spoiler 600 through a first hinge 610, and the driving mechanism 300 is drivingly connected to the lifting frame 100 to drive the lifting frame 100 to move up and down;

[0037] The upper end of the pulling rod 200 is hinged to the spoiler 600 through a second hinge 620, and the pulling rod 200 is provided with a limiting part 201, and the first hinge 610 and the second hinge 620 are arranged in a first direction and are spaced apart from each other, and the first direction is arranged transversely to the up-down direction;

[0038] The limiting mechanism 400 is used to limit the pulling rod 200 to be swingable when the lifting frame 100 is lifted to the first position, and the pulling rod 200 is used to swing relative to the limiting mechanism 400 when the pulling rod 200 is swingably limited.

[0039] In the specification, the spoiler 600 is arranged at the tail of the vehicle and can move in the up-down direction as an example to illustrate the content of the application (the up-down direction is consistent with the Z-axis direction), but it should be understood that the movement direction of the lifting frame 100 can have an angle with the height direction of the vehicle without violating the design concept of the application, and is not limited to being arranged at the tail of the vehicle, and will not be described in detail hereinafter.

[0040] As shown in FIG. 1, the lifting frame 100 is lifted to the first position and moves in the preset area, and the slider 120 of the lifting frame 100 described hereinafter moves in the area corresponding to the “L” shown in FIG. 2, and the displacement of the limiting part 201 of the pulling rod 200 described hereinafter in the up-down direction is limited by the limiting mechanism 400 (for example, limited by the limiting part 410 and the elastic connecting part 420 described hereinafter), and at this time, the pulling rod 200 can swing relative to the limiting mechanism 400. Figure 3 Figure 3

[0041] ​​Thus, in the spoiler device of the present application, the driving mechanism 300 drives the lifting frame 100 to move up and down, when the lifting frame 100 moves to the first position along the up and down direction and moves above the first position, the limiting mechanism 400 forms the swingable limiting to the pull rod 200, at this time, the translation movement of the pull rod 200 in the up and down direction is limited by the limiting mechanism 400, but the pull rod 200 can still swing relative to the limiting mechanism 400, the contact between the pull rod 200 and the limiting mechanism 400 can be equivalent to the rotary connection, the lifting frame 100, the spoiler plate 600, the pull rod 200 and the fixing frame 500 for mounting and fixing described later jointly form a structure similar to a four-bar linkage, when the side length of the pull rod 200 is elongated or shortened, the spoiler plate 600 and the pull rod 200 are linked, wherein the pull rod 200 swings relative to the lifting frame 100, the spoiler plate 600 rotates relative to the lifting frame 100, so as to realize the inclination angle adjustment of the spoiler plate 600; when the lifting frame 100 moves at a position lower than the first position, the limiting mechanism 400 releases the swingable limiting to the pull rod 200, the lifting frame 100 can drive the spoiler plate 600 and the pull rod 200 to move up and down, for example, so that the spoiler plate 600 is stored in the vehicle interior. The lifting and inclination angle adjustment of the spoiler plate 600 in the spoiler device of the present application are driven by the lifting movement of the lifting frame 100, or the driving of the driving mechanism, avoiding the use of multiple drives, without the need for coordinated control between multiple drives, simplifying the overall structure and reducing the probability of drive damage caused by vibration and the like, and the reliability is higher.

[0042] As shown in Figures 1 to 8 Optionally, the pull rod 200 is provided with a limiting portion 201, the limiting mechanism 400 includes a limiting piece 410 and an elastic connecting piece 420, the limiting piece 410 is used for being fixedly arranged above the limiting portion 201, when the limiting portion 201 abuts against the limiting piece 410, the pull rod 200 is used for swinging relative to the limiting piece 410; one end of the elastic connecting piece 420 is connected with the pull rod 200, and the other end is connected with the lifting frame 100 or the spoiler plate 600.

[0043] Specifically, when the lifting frame 100 rises to the abutment between the limiting portion 201 and the limiting piece 410 and continues to rise, the elastic potential energy of the elastic connecting piece 420 increases, and the elastic connecting piece 420 provides a driving force for the upward movement of the pull rod 200 relative to the lifting frame 100.

[0044] The limiting mechanism 400 forms the limiting to the limiting portion 201 in the up and down direction, but the limiting manner does not limit the activity of the limiting portion 201 to a certain extent, for example, rotation, at this time, it is embodied in that the pull rod 200 can swing to a certain extent, so as to adapt to the swing of the spoiler plate 600 relative to the lifting frame 100 at the first hinge 610.

[0045] For the convenience of description, the position before the lifting frame 100 starts to move upward is defined as an initial position, the first position (refer to Figure 3 ) is the lower limit position of the preset region, and the position when the lifting frame 100 moves upward and reaches the upper limit of the preset region is the second position (refer to Figure 7 ).

[0046] As shown in Figure 1 and Figure 2 , before the lifting frame 100 rises to the abutment between the limiting part 201 and the limiting member 410 (i.e., before the lifting frame 100 rises to the first position), the limiting member 410 does not abut against the limiting part 201, and under the action of the elastic connecting member 420, the pull rod 200 moves upward relative to the lifting frame 100 and swings, so that the spoiler 600 rotates relative to the first hinge 610 until the rotation of the spoiler 600 is limited (for example, the spoiler 600 abuts against the end surface of the lifting frame 100 in the front-rear direction and is limited), the spoiler 600 and the pull rod 200 can translate with the lifting frame 100, and the overall height of the spoiler 600 and the pull rod 200 can be adjusted.

[0047] In this way, in the spoiler device of the present application, the driving mechanism 300 drives the lifting frame 100 to move up and down, when the lifting frame 100 moves along the up-down direction to the abutment between the limiting part 201 and the limiting member 410 and continues to rise, the limiting member 410 and the elastic connecting member 420 can jointly limit the translation of the limiting part 201 in the up-down direction but do not limit the rotation of the limiting part 201 relative to the limiting mechanism 400, at this time, the contact between the limiting part 201 and the limiting structure can be equivalent to a rotary connection, and the spoiler 600 and the pull rod 200 are linked, wherein the pull rod 200 swings relative to the lifting frame 100, and the spoiler 600 rotates relative to the lifting frame 100, that is, the inclination angle of the spoiler 600 changes; when the lifting frame 100 stays at a certain position, the first hinge 610 stops rising and falling with the lifting frame 100, and since the limiting part 201 is in a limited state in the up-down direction, at this time, the first hinge 610, the second hinge 620, and the limiting part 201 approximately form a stable triangle, thereby keeping the inclination angle of the spoiler 600 stable.

[0048] In addition, for any position of the lifting frame 100 in the preset region, the spoiler 600 has a corresponding inclination angle, and when the lifting frame 100 continuously slides, the inclination angle of the spoiler 600 will continuously change, the angle of the spoiler 600 can be flexibly adjusted, a large inclination angle adjustment range can be achieved, and the inclination angle can be adjusted according to actual needs, for example, the inclination angle of the spoiler 600 can be adjusted according to the braking force demand or the depression force demand of the vehicle.

[0049] As shown in Figure 1As shown, further, the pull rod 200 is provided in a telescopic structure. It can be a manually telescopic or an automatically telescopic structure, so that the length adjustment of the pull rod 200 can be realized, which will be exemplarily illustrated later.

[0050] In this way, the pull rod 200 is provided in a telescopic structure, on one hand, during the installation of the spoiler device to the vehicle or during the use, the length of the pull rod 200 in the up-down direction can be adjusted according to the use needs, such as the height needs of the spoiler plate 600 and / or the range needs of the tilting angle, so that the adjustment of the initial relative position of the limiting mechanism 400 and the limiting part 201 is realized, and then the position of the lifting frame 100 in the up-down direction when the spoiler plate 600 starts to rotate is adjusted.

[0051] As shown, Figure 1 exemplarily, the pull rod 200 includes a first rod 210 and a second rod 220, the first rod 210 is used to be connected with the spoiler plate 600 through the second hinge 620, and the first rod 210 is adjustably and detachably connected with the second rod 220 in the relative position. For example, a screw sleeve is arranged on one of the first rod 210 and the second rod 220, and a screw rod is arranged on the other one of the first rod 210 and the second rod 220, the screw rod is threadedly connected with the screw sleeve and locked by a nut; of course, in some cases, the screw sleeve can be arranged on both the first rod 210 and the second rod 220, the screw rod is threadedly connected with the screw sleeves at both ends, and the screw threads at both ends of the screw rod are opposite in rotation direction, so that the relative position of the first rod 210 and the second rod 220 can be adjusted without disassembling the pull rod 200 when necessary. The pull rod 200 can further include a third rod 230, the third rod 230 is connected with an end of the second rod 220 away from the first rod 210, the third rod 230 is provided with the limiting part 201 described above, and the third rod 230 can be welded or detachably connected with the second rod 220, one or more of the first rod 210, the second rod 220 and the third rod 230 can be provided in a hollow structure.

[0052] As shown, Figure 4 in the above embodiment, the limiting part 410 is located on the movement path of the lifting frame 100, the limiting part 410 is provided with a through hole 411, and the lifting frame 100 is arranged in the through hole 411. For example, the lifting frame 100 is in sliding connection with the through hole 411.

[0053] Exemplarily, the limiting part 410 is arranged on the fixed frame 500 and located at the upper end of the fixed frame 500, the frame body 110 of the lifting frame 100 is arranged in the through hole 411 and in sliding connection with the through hole 411. The end of the limiting part 410 close to the pull rod 200 is used to limit the limiting part 201 of the pull rod 200.

[0054] At this time, the limiting member 410 can limit the limiting portion 201 and guide the sliding of the lifting frame 100, and can also block the sliding block 120, so that the upper limit position of the upward sliding of the lifting frame 100 is limited, and a mechanical limiting structure does not need to be additionally arranged.

[0055] The limiting member 410 can also be arranged to be adjustable in the up-down direction, so that the similar effect of the telescopic rod 200 in the above embodiment can be obtained, which will not be described in detail here.

[0056] As shown in Figure 3 , the limiting portion 201 includes a protrusion arranged on the side of the telescopic rod 200 close to the lifting frame 100, and the protrusion extends below the limiting member 410.

[0057] Exemplarily, the protrusion is arranged on the third rod 230, and the width of the third rod 230 in the front-rear direction can be smaller than the width of the second rod 220, so that the space requirement of the telescopic rod 200 at the limiting member 410 when swinging can be reduced.

[0058] In this way, when the protrusion abuts against the limiting member 410, the protrusion can still swing in a small range without being separated from the limiting member 410.

[0059] At this time, the contact surface of the limiting member 410 and the protrusion can be arranged as an arc surface, so that good contact can be obtained when the telescopic rod 200 swings.

[0060] As shown in Figure 2 , optionally, the elastic connecting member 420 includes a tension spring 421, and the upper end of the tension spring 421 is connected with the lifting frame 100, and the lower end of the tension spring 421 is connected with the telescopic rod 200.

[0061] For example, the upper end of the tension spring 421 is connected with the part of the lifting frame 100 above the limiting member 410, and at this time, the tension spring 421 can provide the upward movement force of the telescopic rod 200 relative to the lifting frame 100. The principle of the present application is exemplarily described in combination with this case:

[0062] Before the limiting member 410 limits the limiting portion 201, under the action of the initial pre-tension of the tension spring 421, the telescopic rod 200 moves upward relative to the lifting frame 100 and pushes the spoiler 600 to rotate around the first hinge 610, and the posture of the spoiler 600 relative to the lifting frame 100 is locked, for example, the upper surface of the spoiler 600 at this time is kept in a state close to vertical, which can be defined as the initial state of the spoiler device (as shown in Figures 1 to 2 ).

[0063] As shown in Figure 3 and Figure 4As shown, the driving mechanism 300 drives the lifting frame 100 to move upward until the limiting part 201 moves to the limiting part 410, and the limiting part 410 forms a limit to the limiting part 201. At this time, the limiting part 410 can only abut against the limiting part 201. During the sliding process of the lifting frame 100, the position of the spoiler 600 remains unchanged under the action of the tension of the tension spring 421 or other structures.

[0064] As shown in Figures 5 to 7 which shows the angle change of the spoiler 600 during the upward movement of the lifting frame 100 driven by the driving mechanism 300. During this process, the tension of the tension spring 421 increases continuously, the limiting part 410 keeps limiting the limiting part 201, the height of the first hinge 610 of the spoiler 600 in the up-down direction continuously rises, and the spoiler 600 continuously rotates around the first hinge 610, thereby realizing the angle adjustment of the spoiler 600.

[0065] As shown in Figure 1 The spoiler device can also include a fixed frame 500. The lifting frame 100 is in sliding connection with the fixed frame 500 in the up-down direction. The driving mechanism 300 is installed on the fixed frame 500 and is in driving connection with the lifting frame 100.

[0066] For example, the fixed frame 500 is fixedly arranged on the shell of the rear door of the vehicle, and when the rear door is opened, the spoiler device moves with the rear door as a whole.

[0067] Optionally, the driving mechanism 300 includes a driving part 310 and a threaded transmission part 320. The driving part 310 is in driving connection with the threaded transmission part 320. The threaded transmission part 320 is in screw transmission connection with the lifting frame 100.

[0068] As shown in Figure 2 Exemplarily, the driving part 310 can include a motor 311 and a worm gear reducer 312. The shell of the worm gear reducer 312 is installed on the fixed frame 500. The motor 311 is installed on the shell of the worm gear reducer 312 and is in driving connection with the worm gear reducer 312. The output end of the worm gear reducer 312 is connected with the threaded transmission part 320, thereby driving the threaded transmission part 320 to rotate.

[0069] In this way, the driving part 310 drives the threaded transmission part 320 to rotate and is in screw transmission connection with the lifting frame 100, thereby converting the rotary motion of the threaded transmission part 320 into the sliding of the lifting frame 100 on the guide rail 510. The transmission is smooth in the screw transmission mode, so that the lifting frame 100 slides smoothly in the up-down direction, and the angle adjustment of the spoiler 600 is more smooth.

[0070] Further, the lifting frame 100 comprises a frame body 110 and a sliding block 120 arranged at the bottom of the frame body 110, the fixed frame 500 is provided with a guide rail 510, and the sliding block 120 is in sliding connection with the guide rail 510; the screw transmission member 320 comprises a lead screw, and the lead screw is arranged through the sliding block 120 and is in screw transmission connection with the sliding block 120.

[0071] The upper end of the lead screw is rotatably arranged on the fixed frame 500 through a bearing.

[0072] Illustratively, the sliding block 120 is provided with a guide sliding groove corresponding to the guide rail 510, so as to realize the sliding of the sliding block 120 on the guide rail 510, the lead screw is provided with an external thread, and the sliding block 120 is provided with an internal thread hole matched with the external thread, so that the rotation of the lead screw drives the sliding block 120 to slide on the guide rail 510.

[0073] Illustratively, the two ends of the lead screw are rotatably arranged on the fixed frame 500 through bearings, that is, the two ends of the lead screw are provided with bearing connecting portions for connecting the bearings, and the fixed frame 500 can form better rotation support for the lead screw. In this case, the connection between the frame body 110 and the sliding block 120 is staggered with the lead screw, so as to avoid the interference of the frame body 110 with the lead screw (not shown in the figure).

[0074] Differently from the above-mentioned scheme that the upper end of the lead screw is rotatably arranged on the fixed frame 500 through a bearing, alternatively, the lower end of the frame body 110 is arranged as a hollow structure, and the hollow structure is used for accommodating the one end of the lead screw passing through the sliding block 120.

[0075] In this case, the mounting structure of the screw transmission member 320 can be simplified, and the weight and space occupation are reduced.

[0076] It should be understood that the sliding block 120 can be detachably connected with the frame body 110, so as to facilitate the processing of the sliding block 120, and of course, the integral connection can also be arranged.

[0077] As shown in FIG. 1, Figure 1 In the optional embodiment of the application, when the lifting frame 100 is lower than the first position, the limiting mechanism 400 releases the swingable limiting, that is, the limiting portion 201 is separated from the limiting member 410, and the lifting frame 100 is used for lifting the spoiler 600 to extend outside the vehicle or to be retracted inside the vehicle.

[0078] In this way, the spoiler 600 can be retracted inside the vehicle when not in use, and the spoiler 600 can be extended outside the vehicle when in use, so that the hidden design of the spoiler device can be realized.

[0079] As shown in FIG. 1, Figure 1As shown, optionally, the first hinge 610 is located in front of the second hinge 620, and the front end face of the lifting frame 100 is used to abut against the lower surface of the spoiler 600 when the limiting part 201 is separated from the limiting member 410.

[0080] It should be noted that the spoiler 600 includes two surfaces with large surface areas, wherein, in the usage state (refer to...) Figure 5 The side facing upwards is the upper surface, and the side facing downwards is the lower surface.

[0081] Specifically, when the limiting part 201 separates from the limiting member 410, driven by the elastic force of, for example, the tension spring 421, the pull rod 200 moves upward relative to the lifting frame 100, thereby causing the spoiler 600 to rotate counterclockwise around the first hinge member 610 until the lower surface of the spoiler 600 is aligned with the front end face of the lifting frame 100. At this time, the upper surface of the spoiler 600 faces forward or upward, and the front end of the spoiler 600 is at the height of the first hinge member 610 in the vertical direction.

[0082] Thus, on the one hand, the first hinge 610 is located in front of the second hinge 620, that is, the lifting frame 100 is located in front of the tie rod 200. When the spoiler 600 is in use (i.e., in an inclined state), the top height of the lifting frame 100 is relatively low. Compared with setting the first hinge 610 behind the second hinge 620, the lifting stroke requirement of the lifting frame 100 can be reduced, thereby reducing the height requirement of the lifting frame 100 and the fixed frame 500 to a certain extent, and reducing the overall weight of the spoiler device. On the other hand, the spoiler 600 can extend out of the vehicle or retract into the vehicle in an inclined posture relative to the lifting frame 100, which can reduce the size of the through slot opened on the vehicle for the spoiler 600 to pass through.

[0083] Specifically, the distance from the first hinge 610 to the lower surface of the spoiler 600 is less than the distance from the second hinge 620 to the lower surface of the spoiler 600, and the distance from the first hinge 610 to the lower surface of the spoiler 600 is greater than or equal to the distance from the first hinge 610 to the front end face of the lifting frame 100.

[0084] For ease of explanation, using Figure 7 The above solution is illustrated using the case where the front and rear ends of the spoiler 600 are at approximately the same height. In this case, the lower surface of the spoiler 600 is considered a plane. For example, a vertical plane (parallel to the YZ plane) passing through the center line of the first hinge 610 is drawn. The point at the lowest end of the line intersecting the arc portion of the lower surface of the spoiler 600 with this plane is defined as the calibration point. A plane parallel to the XY plane is drawn through the calibration point, and this plane can be considered as the lower surface of the spoiler 600. Simply put, in this state, the first hinge 610 is positioned higher than the second hinge 620 in the vertical direction.

[0085] Thus, the first hinge 610 is closer to the lower surface of the spoiler 600 than the second hinge 620, and during counterclockwise rotation of the spoiler 600 relative to the first hinge 610, the second hinge 620 has a relatively small change in position in the front-rear direction before the spoiler 600 abuts against the front end surface of the lifting frame 100, so the swing range of the pull rod 200 is small, and the distance between the pull rod 200 and the lifting frame 100 can be designed to be small, and the structure is compact. Since the distance from the first hinge 610 to the lower surface of the spoiler 600 is greater than or equal to the distance from the first hinge 610 to the front end surface of the lifting frame 100, the spoiler 600 can be rotated counterclockwise around the first hinge 610 until the lower surface of the spoiler 600 moves entirely to the front of the front end surface of the lifting frame 100, and when the spoiler 600 is further rotated counterclockwise, the lower surface of the spoiler 600 abuts against the front end surface of the lifting frame 100, so that the spoiler 600 can be rotated within a large angle range.

[0086] In an optional embodiment of the application, the distance from the first hinge 610 to the front end surface of the spoiler 600 (defined as the first distance) is greater than the distance from the first hinge 610 to the rear end surface of the spoiler 600 (defined as the second distance).

[0087] The first distance and the second distance are exemplarily illustrated as follows. A first plane (the first plane is parallel to the YZ plane) passing through the center line of the first hinge 610, for example, a first plane passing through the center of the first hinge 610 and perpendicular to the first hinge 610, is defined, and the intersection points of the front and rear ends of the upper surface of the spoiler with the first plane are defined as the first point and the second point, respectively. When the first point and the second point are substantially at the same height, a first connecting line is obtained by connecting the first point and the second point, and a second plane perpendicular to the first connecting line is obtained by passing through the center line of the first hinge 610. At this time, the distance from the first point to the second plane is approximately the first distance, and the distance from the second point to the second plane is approximately the second distance. The first distance can be, for example, 1.02-1.4 times, for example, 1.05-1.2 times, 1.1 times the second distance.

[0088] Specifically, at this time, the area of the portion of the upper surface of the spoiler 600 located in front of the second plane is relatively large. The action point of the resultant force of the negative lift (i.e., the downward force) generated by the air passing through the spoiler 600 is located in front of the first hinge 610, so that at this time, the elastic force requirement of the elastic connecting member 420 under the action of the negative lift can be reduced, and the reliability is high.

[0089] Conversely, in the front-rear direction, if the action point of the downward pressure received by the spoiler 600 and the second hinge 620 are both located on the same side of the first hinge 610, the elastic force of the elastic connecting piece 420 is required to maintain the position of the limiting portion 201 in the up-down direction when the downward pressure is received. In this case, if the downward pressure is too large, the inclination angle of the spoiler 600 may fluctuate within a certain angle range, which is not conducive to adjusting the inclination angle of the spoiler 600 according to actual needs, and at this time, the elastic connecting piece 420 may need to provide a large elastic force.

[0090] The arrangement mode of the elastic connecting piece 420 is not limited to the case of the tension spring 421, and alternatively, the elastic connecting piece 420 includes a compression spring arranged on the lifting frame 100 and used to lift the lifting frame 100, the compression spring is located below the limiting portion 201, and the compression spring abuts against the limiting portion 201.

[0091] Exemplarily, the sliding block 120 is provided with a mounting portion extending to the lower side of the limiting portion 201 in the reverse direction of the Y-axis, a compression spring such as a disc spring is mounted on the mounting portion, and the upper surface of the mounting portion can be arranged lower than the upper surface of the sliding block 120, so that the compression spring can provide a driving force for the upward movement of the limiting portion 201 relative to the lifting frame 100. When the lifting frame 100 slides upward and the limiting portion 201 abuts against the limiting piece 410, the compression spring can provide an abutting force between the limiting portion 201 and the limiting piece 410 (this scheme is not shown).

[0092] As shown in Figure 4 Further, the lifting frame 100 is provided with a groove 121 extending in the up-down direction, the groove 121 is arranged towards the pull rod 200 (that is, the groove 121 extending in the up-down direction is formed on the side in the reverse direction of the Y-axis), the pull rod 200 is provided with a convex column 202 below the limiting portion 201, and the convex column 202 is slidingly arranged in the groove 121.

[0093] In this way, before the lifting frame 100 moves to the preset area, that is, before the limiting portion 201 abuts against the limiting piece 410, the convex column 202 abuts against the groove bottom of the groove 121 (the groove bottom is located in the positive direction of the Y-axis), so as to maintain the static state of the spoiler 600 relative to the lifting frame 100, and the groove wall of the groove 121 forms a limiting for the convex column 202 in the X-axis direction, which has high reliability.

[0094] It should be understood that the way of keeping the spoiler 600 stationary relative to the lifting frame 100 before the lifting frame 100 moves to the preset area is not limited to this, for example, a pad can be arranged on the upper portion of the frame body 110, the pad is in abutment with the pull rod 200 in the Y-axis direction before the limiting portion 201 abuts against the limiting member 410, and the abutment position is above the limiting portion 201 (not shown in the scheme). Alternatively, the limiting of the limiting member 410 to the limiting portion 201 can also be that the limiting portion 201 comprises a cylinder extending along the X-axis direction, the cylinder can be arranged on both sides of the bottom of the pull rod 200 along the X-axis direction, the limiting member 410 is provided with a limiting groove matched with the cylinder, the limiting groove is arranged corresponding to the cylinder, and the cross-sectional shape of the limiting groove in the ZY plane is a U-shaped structure with the opening facing downward, and the limiting groove is used to form the limiting of the limiting column when the lifting frame 100 moves upward and the limiting column moves to the top of the limiting groove, and the top of the limiting groove is rotationally connected with the limiting column. In this way, before the lifting frame 100 moves to the preset position, the pose of the spoiler 600 relative to the lifting frame 100 does not change, and during the subsequent upward movement of the lifting frame 100, the pull rod 200 can swing around the limiting column, and the limiting groove can provide stable and reliable limiting (not shown in the scheme).
