Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to a concealed spoiler assembly and vehicle. Background Technology

[0002] Spoilers such as rear wings on cars are mainly used to reduce lift and improve the car's traction. However, they generally only reduce lift at high speeds. At low speeds, they can actually hinder the car's movement due to wind resistance, increasing energy consumption.

[0003] To address this issue, a concealed spoiler assembly has emerged in current technology. When in use, the spoiler extends outside the vehicle; when not in use, it retracts inside the vehicle and its openings are covered by a hatch, resulting in a streamlined vehicle surface and reducing energy consumption at low speeds. However, its operation requires actions such as opening and closing the hatch, extending and retracting the spoiler, and adjusting its angle. These actions are driven by different motors, and failure of any one of these motors could cause the concealed spoiler assembly to malfunction. For example, a collision between the hatch and the spoiler could occur, posing a safety hazard and indicating insufficient operational stability. Summary of the Invention

[0047] like Figures 1 to 16 As shown, an embodiment of the present invention provides a concealed spoiler assembly, which includes:

[0048] The column 100 and the driving mechanism 400, the driving mechanism 400 is used for driving the column 100 to lift along the up and down direction;

[0049] The switch mechanism 300 is arranged between the column 100 and the fixed frame 500, and the switch mechanism 300 is used for converting the lifting movement of the column 100 into the opening and closing action of the hatch door 620, so as to open or close the through hole 631 on the vehicle for the spoiler 610 to pass through;

[0050] The upper end of the inclination adjustment mechanism 200 and the upper end of the column 100 are respectively used for being hinged with different positions of the spoiler 610 in the front and rear direction, and the inclination adjustment mechanism 200 is used for converting the lifting movement of the column 100 into the rotating movement of the spoiler 610 when the spoiler 610 is at least partially located outside the vehicle.

[0051] As Figure 1 shown, the present application will be used for the tail of the vehicle, and specifically, the through hole 631 is opened in the back door 630, and the content of the present application is illustrated by taking the back door 630 as an example. At this time, the fixed frame 500 can be mounted on the back door 630, for example, on the inner surface of the back door 630. The back door 630 can be provided with a storage body for accommodating the fixed frame 500 and the like. The fixed frame 500 can also be directly exposed to the inside of the luggage compartment. It should be understood that it can also be used in other positions without violating the design concept of the present application. According to the different positions, the mounting and connecting modes of the components can be adjusted as needed, and the lifting direction of the column 100 can also have an angle with the height direction of the vehicle, which is not as a limitation.

[0052] It should be understood that when the spoiler 610 is at least partially located outside the vehicle, the inclination adjustment mechanism 200 converts the lifting movement of the column 100 into the rotating movement of the spoiler 610. At this time, the edge of the through hole 631 should not form an obstacle to the spoiler 610.

[0053] The present application mainly utilizes the switch mechanism 300 to convert the lifting movement of the column 100 into the opening and closing action of the hatch door 620, and utilizes the inclination adjustment mechanism 200 to convert the lifting movement of the column 100 into the inclination adjustment movement of the spoiler 610. On this basis, the structures of the switch mechanism 300 and the inclination adjustment mechanism 200 are not as a limitation, and will be exemplarily illustrated later.

[0054] It should be understood that the inclination adjustment here can be the inclination adjustment between two states such as the initial position and the use position, or the inclination adjustment between multiple use positions, or even continuous adjustment.

[0055] Thus, the hidden spoiler assembly of the present application, the stand 100 is lifted along the up-down direction, in particular, the stand 100 is lifted under the driving of the driving mechanism 400, the spoiler 610 can be moved to the outside of the vehicle or retracted to the inside of the vehicle by the lifting of the stand 100, in the process, the lifting movement of the stand 100 is converted into the opening and closing movement of the hatch 620 by the switch mechanism 300, so as to open or close the through hole 631 on the vehicle for the spoiler 610 to pass through, when the spoiler 610 is at least partially located outside the vehicle, the tilt angle adjusting mechanism 200 converts the lifting movement of the stand 100 into the rotating movement of the spoiler 610, so as to realize the tilt angle adjustment of the spoiler 610. In the present application, the lifting movement of the stand 100 can drive the spoiler 610 to lift, the tilt angle adjustment of the spoiler 610 can be realized through the tilt angle adjusting mechanism 200, and the driving of the hatch 620 can be realized through the switch mechanism 300, which can reduce the number of drives, thereby reducing the probability of drive damage caused by vibration and the like relative to the scheme of multiple drives, having higher use stability, higher reliability and safety.

[0056] The tilt angle adjusting mechanism 200 is exemplarily described below.

[0057] The tilt angle adjusting mechanism 200 includes a swing structure 210 and a limiting structure, the upper end of the swing structure 210 is used for being hinged with the spoiler 610, when the spoiler 610 is at least partially located outside the vehicle, the limiting structure is used for forming the swingable limiting of the swing structure 210, and the swing structure 210 is used for swinging relative to the limiting structure.

[0058] When the limiting structure forms the swingable limiting of the swing structure 210, the parallel movement of the swing structure 210 upward is limited, but the swing structure 210 can still swing relative to the limiting structure, at this time, when the stand 100 is lifted, the lifting movement of the stand 100 can be converted into the rotation of the spoiler 610 through the swing of the swing structure 210, and this conversion can be understood as forced adaptive conversion.

[0059] Optionally, the limiting structure includes a first limiting piece 220, the upper end of the swing structure 210 and the upper end of the stand 100 are respectively used for being hinged with the spoiler 610 at different positions in the front-rear direction, the swing structure 210 is provided with a first limiting part 2111, the first limiting piece 220 is arranged on the fixed frame 500 and located above the first limiting part 2111, when the first limiting part 2111 abuts against the first limiting piece 220, the swing structure 210 is used for swinging relative to the first limiting piece 220.

[0060] Specifically, the upper end of the column 100 is hinged to the spoiler 610 through a first hinge 640, and the upper end of the swing structure 210 is hinged to the spoiler 610 through a second hinge 650, for example, the first hinge 640 and the second hinge 650 are both pin shafts.

[0061] The working mode of the inclination adjustment mechanism 200 is exemplarily described as follows:

[0062] As shown in Figures 7 to 9 , before the column 100 moves upward and the first limiting part 2111 abuts against the first limiting part 220, the spoiler 610 is kept in an initial position relative to the column 100 under the action of an initial holding force, for example, the initial holding force can be kept by a first return part 230 such as a tension spring 231, gravity, or a clamping structure, and in the drawings of the present specification, the front end of the spoiler 610 is lower than the rear end in the initial position, for example, the first hinge 640 is in front of the second hinge 650, at this time, the lower surface of the spoiler 610 can abut against the front end surface of the column 100, and at this time, the first limiting part 220 is above the first limiting part 2111.

[0063] As shown in Figure 10 , at this time, the column 100 moves upward to abut the first limiting part 2111 against the first limiting part 220, and the first limiting part 220 limits the upward movement of the first limiting part 2111, but does not limit the swing of the first limiting part 2111 relative to the first limiting part 220.

[0064] As shown in Figure 11 and Figure 12 , since the first limiting part 2111 of one movable end of the swing structure 210 is limited by the first limiting part 220, the spoiler 610 cannot realize the overall translation movement upward, when the column 100 continues to rise, the spoiler 610 and the swing structure 210 are linked, the swing structure 210 swings relative to the first limiting part 220, and the spoiler 610 rotates relative to the first hinge 640 (for example, the rear end of the spoiler 610 moves downward), thereby realizing the inclination adjustment of the spoiler 610.

[0065] Exemplarily, when the column 100 moves upward to abut the first limiting part 2111 against the first limiting part 220 and continues to move upward, the spoiler 610 rotates in a second direction (clockwise as shown in the YZ plane) around the first hinge 640, Figures 10 to 11 , the inclination adjustment mechanism 200 includes a first return part 230, and the first return part 230 is used for resetting the spoiler 610, and the first return part 230 is used for providing the initial holding force of the spoiler 610.

[0066] Thus, when the column 100 rises to the abutment between the first limiting part 2111 and the first limiting member 220, the first limiting member 220 limits the upward translation of the first limiting part 2111 of the swing structure 210 but does not limit the swing of the swing structure 210, the swing structure 210 and the spoiler 610 are linked, the swing structure 210 swings relative to the first limiting part 2111, and the spoiler 610 rotates relative to the column 100, so that the inclination adjustment of the spoiler 610 can be realized.

[0067] As shown in Figure 1 , Figures 5 to 10 , the swing structure 210 includes a pull rod 211, the upper end of the pull rod 211 is hinged to the spoiler 610, the lower end of the pull rod 211 is provided with the first limiting part 2111, one end of the first reset member 230 is connected to the pull rod 211, and the other end is used to be connected to the column 100 or the spoiler 610.

[0068] As shown in Figures 7 to 9 , before the column 100 rises to the abutment between the first limiting part 2111 and the first limiting member 220, the first limiting member 220 is not in abutment with the first limiting part 2111, under the action of the first reset member 230, the pull rod 211 moves upward relative to the column 100 and swings, so that the spoiler 610 rotates relative to the first hinge 640 until the spoiler 610 is limited in rotation (for example, the spoiler 610 is in abutment with the end surface of the column 100 in the front-back direction and is limited), and the spoiler 610 and the pull rod 211 can translate integrally with the column 100.

[0069] As shown in Figure 10 and Figure 12 , when the slider 120 (indicated in the middle) of the column 100 Figure 1 in Figure 10When the lifting is within the region "L" shown, the first limiting part 2111 and the first limiting part 220 always remain in the abutting state under the action of the first reset part 230, even if the slider 120 of the column 100 moves downward within the region "L" (hereinafter referred to as a preset region). Specifically, during this process, the first limiting part 220 and the first reset part 230 can jointly limit the translation of the first limiting part 2111 in the up-down direction but do not limit the rotation of the first limiting part 2111 relative to the first limiting part 220. At this time, the contact between the first limiting part 2111 and the first limiting part 220 can be equivalent to a rotating connection, and the spoiler 610 and the pull rod 211 are linked, wherein the pull rod 211 swings relative to the column 100, and the spoiler 610 rotates relative to the column 100, that is, the inclination angle of the spoiler 610 changes. When the column 100 stops at a certain position, the first hinged part 640 stops lifting with the column 100. Since the first limiting part 2111 is in a limited state in the up-down direction, the first hinged part 640, the second hinged part 650, and the first limiting part 2111 approximately form a stable triangle, thereby keeping the inclination angle of the spoiler 610 stable.

[0070] In addition, at any position in the preset region, the spoiler 610 has a corresponding inclination angle. When the column 100 continuously slides, the inclination angle of the spoiler 610 will continuously change, enabling flexible adjustment of the angle of the spoiler 610, so that the inclination angle can be adjusted according to actual needs, for example, the inclination angle of the spoiler 610 is adjusted according to the braking force demand or the down pressure demand of the vehicle.

[0071] As shown in 1 and Figure 15 Optionally, the first limiting part 220 is located on the movement path of the column 100, and the first limiting part 220 is provided with a first through hole 221, and the column 100 is arranged in the first through hole 221; the first limiting part 2111 includes a protrusion arranged on the side of the pull rod 211 close to the column 100, and the protrusion extends below the first limiting part 220.

[0072] Exemplarily, the first limiting part 220 is arranged at the upper end of the fixed frame 500, the column body 110 of the column 100 is arranged in the first through hole 221 and is in sliding connection with the first through hole 221, the bottom of the column body 110 is provided with the slider 120, and the first limiting part 220 is used to limit the first limiting part 2111.

[0073] At this time, the first limiting part 220 can not only limit the first limiting part 2111, but also guide the sliding of the column 100. In addition, the first limiting part 220 can also block the slider 120, thereby limiting the upper limit position of the upward sliding of the column 100, without the need for additional mechanical limiting structures.

[0074] When the protrusion abuts against the first limiting member 220, the protrusion can still swing within a small range without disengaging from the first limiting member 220. The contact surface between the first limiting member 220 and the protrusion can be set as an arc surface, so that good contact can be achieved when the pull rod 211 swings.

[0075] like Figure 5 As shown, optionally, the first reset member 230 includes a tension spring 231, the upper end of which is connected to the column 100, and the lower end of which is connected to the pull rod 211. For example, the upper end of the tension spring 231 is connected to the portion of the column 100 located above the first limiting member 220.

[0076] At this time, the tension spring 231 can not only provide a restoring force, but also make the lower end of the pull rod 211 stick to the column 100, so as to prevent the lower end of the pull rod 211 from swaying back and forth.

[0077] The first reset member 230 can be configured in a manner not limited to the case of the tension spring 231 described above. Optionally, the first reset member 230 includes a compression spring, which is disposed on the column 100 and used to move up and down with the column 100. The compression spring is located below the pull rod 211 and abuts against the pull rod 211. For example, the slider 120 is provided with a mounting part that extends in the opposite direction to the Y-axis to below the pull rod 211. A compression spring, such as a disc spring, is mounted on the mounting part. The upper surface of the mounting part may be set lower than the upper surface of the slider 120 (this option is not shown).

[0078] like Figure 1 He Ru Figure 13 As shown, the column 100 is further provided with a groove 140 extending in the vertical direction. The groove 140 is positioned towards the pull rod 211. A protrusion 2112 is provided below the first limiting part 2111 on the pull rod 211. The protrusion 2112 is slidably disposed in the groove 140.

[0079] In this way, before the column 100 moves to the preset area, that is, before the first limiting part 2111 abuts against the first limiting member 220, the protrusion 2112 abuts against the bottom of the groove 140 (the bottom of the groove is located in the positive direction of the Y axis), thereby keeping the spoiler 610 stationary relative to the column 100. The groove wall of the groove 140 forms a limit on the protrusion 2112 in the X-axis direction, which has high reliability.

[0080] Optionally, the column 100 and the fixing frame 500 are slidably connected in the vertical direction. The drive mechanism 400 includes a drive member 410 and a threaded transmission member 420. The drive member 410 and the threaded transmission member 420 are drivenly connected, and the threaded transmission member 420 is helically connected to the column 100.

[0081] The fixed frame 500 is fixedly arranged on a housing of a rear door 630 at the rear of the vehicle, and when the rear door 630 is opened, each component moves as a whole with the rear door 630. The driving member 410 can include a motor 411 and a worm gear reducer 412, the housing of the worm gear reducer 412 is mounted on the fixed frame 500, the motor 411 is mounted on the housing of the worm gear reducer 412, and the motor 411 is drivingly connected with the worm gear reducer 412, and the output end of the worm gear reducer 412 is connected with the threaded transmission member 420, so as to drive the threaded transmission member 420 to rotate.

[0082] As shown in Figure 13 Further, the threaded transmission member 420 includes a lead screw, the lead screw is arranged through the sliding block 120 and is in screw transmission connection with the sliding block 120, and the upper end of the lead screw is rotatably mounted on the fixed frame 500 through a bearing.

[0083] Exemplarily, both ends of the lead screw are rotatably mounted on the fixed frame 500 through bearings, that is, both 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. The fixed frame 500 is provided with a guide rail, the sliding block 120 is provided with a guide sliding groove 311 corresponding to the guide rail, so as to realize sliding of the sliding block 120 on the guide rail, the lead screw is provided with external threads, and the sliding block 120 is provided with internal thread holes matched with the external threads, so that rotation of the lead screw drives the sliding block 120 to slide on the guide rail, and in this case, the connecting position of the column body 110 and the sliding block 120 is staggered with the lead screw, so as to avoid interference of the column body 110 with the lead screw (not shown in the figure).

[0084] Differently from the above-mentioned scheme that the upper end of the lead screw is rotatably mounted on the fixed frame 500 through a bearing, alternatively, the lower end of the column body 110 is provided as a hollow structure for accommodating the end of the lead screw passing through the sliding block 120.

[0085] In this way, the smoothness of the lifting of the column 100 in the screw transmission mode is better, and the angle adjustment of the spoiler 610 is more smooth.

[0086] As shown in Figure 1 Alternatively, the first hinge member 640 is located in front of the second hinge member 650, and the front end face of the column 100 is used to abut against the lower surface of the spoiler 610 when the first limiting portion 2111 is separated from the first limiting member 220. The spoiler 610 includes two surfaces with large areas, one surface facing upward in the use state is an upper surface, and one surface facing downward in the use state is a lower surface.

[0087] Specifically, the distance from the first hinged part 640 to the lower surface of the spoiler 610 is less than the distance from the second hinged part 650 to the lower surface of the spoiler 610, and the distance from the first hinged part 640 to the lower surface of the spoiler 610 is greater than or equal to the distance from the first hinged part 640 to the front end surface of the stand 100.

[0088] In this way, on the one hand, the first hinged part 640 is located in front of the second hinged part 650, that is, the stand 100 is located in front of the pull rod 211, and when the spoiler 610 is in the use state (i.e., the inclined state), the top end of the stand 100 is relatively low in height, which can reduce the lifting stroke requirement of the stand 100, thereby reducing the height requirement of the stand 100 and the fixing frame 500 to a certain extent, and reducing the overall weight of the spoiler device; on the other hand, the spoiler 610 can extend outside the vehicle or retract inside the vehicle in an inclined posture relative to the stand 100, which can reduce the size of the through hole 631 opened on the vehicle for the spoiler 610 to pass through.

[0089] In an optional embodiment of the application, when the swing rod structure is the pull rod 211, the distance from the first hinged part 640 to the front end surface of the spoiler 610 is greater than the distance from the first hinged part 640 to the rear end surface of the spoiler 610.

[0090] At this time, the area of the part of the upper surface of the spoiler 610 located in front of the first hinged part 640 is relatively large. The action point of the resultant force of the negative lift (i.e., the downward pressure) generated by the air passing through is located in front of the first hinged part 640, so that under the action of the negative lift, the elastic force requirement of the first reset part 230 can be reduced, and the reliability is high.

[0091] It should be understood that the arrangement of the swing structure 210 is not limited to this, for example, the swing structure 210 can be a swing rod mechanism, the upper end of the swing rod mechanism is hinged to the spoiler 610, and the lower end is provided with a first limiting part 2111. The swing rod mechanism includes a third swing rod, the rear end of the third swing rod is hinged to the upper end of a second connecting rod 382, and the lower end of the second connecting rod 382 is provided with the first limiting part 2111. The upper end of a first connecting rod 381 is hinged to the spoiler 610 in front of the stand 100, and the lower end of the first connecting rod 381 is hinged to the front end of the third swing rod. At this time, the first reset part 230 can be connected to the front end of the spoiler 610 and the rear end of the third swing rod, respectively (this scheme is not shown).

[0092] The switch mechanism 300 will be described below.

[0093] As Figure 1As shown, the switch mechanism 300 comprises a first swing lever 310 hinged to the fixed frame 500 and a guide sliding column 320 arranged on the stand 100, the first swing lever 310 is provided with a guide sliding groove 311, the guide sliding column 320 is arranged in the guide sliding groove 311 in a slidable and rotatable manner, and the first swing lever 310 is used to swing relative to the guide sliding column 320 and drive the hatch 620 to act.

[0094] As shown in the drawings, Figure 1 The working mode of the switch mechanism 300 is exemplarily explained as follows: the guide sliding groove 311 comprises a swing section (for example, the first groove section 3111 and the second groove section 3112 described later), the swing section is arranged obliquely relative to the up-down direction,

[0095] When the stand 100 moves upward until the guide sliding column 320 is located in the swing section and continues to move upward, the first swing lever 310 rotates in the first direction due to the hinging of the first swing lever 310 and the fixed frame 500, thereby driving the hatch 620 to act, for example, to open; when the stand 100 moves downward until the guide sliding column 320 is located in the swing section and continues to move downward, the first swing lever 310 rotates in the reverse direction of the first direction due to the hinging of the first swing lever 310 and the fixed frame 500, thereby driving the hatch 620 to act, for example, to close. The driving connection mode of the first swing lever 310 and the hatch 620 is not limited, and simply speaking, the first swing lever 310 is in rotational motion, and the opening and closing action of the hatch 620 can also be rotational motion, and the transmission of rotational motion between different positions can be in various modes such as belt transmission, gear transmission and chain transmission.

[0096] As shown in the drawings, Figure 1 , Figures 7 to 12 As shown in the drawings, the swing section comprises the first groove section 3111 and the second groove section 3112 which are connected in the up-down direction, and the first swing lever 310 is rotatably connected to the fixed frame 500 through the first shaft 520.

[0097] The first shaft 520 is arranged close to the connection of the first groove section 3111 and the second groove section 3112, the first groove section 3111 and the second groove section 3112 are respectively arranged obliquely relative to the up-down direction, and the oblique directions are consistent.

[0098] Alternatively, in the up-down direction, the first shaft 520 is arranged at one end of the first swing lever 310, the first groove section 3111 and the second groove section 3112 are respectively arranged obliquely relative to the up-down direction, and the oblique directions are opposite.

[0099] Specifically, the swing section has a third reference surface, and the two side walls of the first groove section 3111 in the width direction are symmetrically arranged about the third reference surface, the distance from the first shaft 520 to the third reference surface is a third distance, and the first distance and the third distance are not equal.

[0100] The first slot section 3111 is located below the second slot section 3112, and when the column 100 is lifted to the position where the spoiler 610 is located at the axial inner end of the through hole 631, the first slot section 3111 is used for sliding and rotating relative to the guide sliding column 320; when the column 100 is lifted to the position where the spoiler 610 is located at the axial outer end of the through hole 631, the second slot section 3112 is used for sliding and rotating relative to the guide sliding column 320.

[0101] That is, when the guide sliding column 320 passes through the first slot section 3111 and the second slot section 3112, the first swing lever 310 swings relative to the guide sliding column 320 and the swinging direction is opposite, so that in the process of lifting the column 100, when the guide sliding column 320 passes through the first slot section 3111, the cabin door 620 can be driven to open by the swing of the first swing lever 310, and when the guide sliding column 320 passes through the second slot section 3112, the cabin door 620 can be driven to close by the swing of the first swing lever 310, that is, when the spoiler 610 is located outside the vehicle, the cabin door 620 can be closed by the movement of the guide sliding column 320 in the second slot section 3112, which can reduce the wind resistance at the through hole 631 to a certain extent when the spoiler 610 works (see Figures 2 to 4 ).

[0102] It should be understood that in the process of lifting the column 100, the cabin door 620 also needs to pass through the through hole 631, and the column 100 will be lifted to a certain height, at this height, if it is desired that the cabin door 620 does not act at this height, a third slot section 3113 described later can be arranged between the first slot section 3111 and the second slot section 3112, or an intermittent driving structure can be arranged between the first swing lever 310 and the driving of the cabin door 620, for example, the first swing lever 310 drives the first rotating member 341 described later, the first rotating member 341 is a gear, so that when the guide sliding column 320 moves in the first slot section 3111, the first swing lever 310 drives the first rotating member 341 to rotate through an angle of less than 360° (hereinafter referred to as a first included angle), and the teeth are arranged only on the initial arc segment in the corresponding range of the first included angle, that is, only in the range of the second included angle, the rotation of the first rotating member 341 will be transmitted to the subsequent link. In this way, the opening and closing actions of the cabin door 620 can be realized, and the intermittent action of the cabin door 620 can also be realized.

[0103] Further, the guide sliding groove 311 further comprises a sliding section, the distance between the first shaft 520 and the first reference plane is a first distance, and the distance between the first shaft 520 and the second reference plane is a second distance, the first distance and the second distance are equal, wherein the center line of the guide sliding column 320 and the movement path of the center line are located on the first reference plane, and the second reference plane is the symmetry plane of the sliding section in the width direction.

[0104] That is, when the guide sliding column 320 is located in the sliding section, it only slides relative to the first swing lever 310, and the first swing lever 310 does not swing.

[0105] As shown in Figure 1 , Figures 7 to 12 , specifically, the sliding section includes one or more of a third slot section 3113, a fourth slot section 3114 and a fifth slot section 3115, the third slot section 3113 is located between the first slot section 3111 and the second slot section 3112, and the fourth slot section 3114 and the fifth slot section 3115 are respectively located at the end of the first slot section 3111 and the second slot section 3112 away from each other.

[0106] Taking the third slot section 3113, the fourth slot section 3114 and the fifth slot section 3115 as an example, the second calibration surface corresponding to the third slot section 3113, the fourth slot section 3114 and the fifth slot section 3115 is not the same, which is not as a limitation.

[0107] Specifically, the rear door 630 is provided with a first mounting seat 383 (as shown in Figure 15 ), for example, the first mounting seat 383 is arranged on the inner side of the outer plate or the inner plate of the rear door 630 and is located at the front side of the through hole 631 (i.e. on the positive side of the Y axis in the figure), and the hatch 620 is pivotally connected to the first mounting seat 383. The first swing rod 310 is located on the left side of the fixed frame 500 (i.e. on the negative side of the X axis).

[0108] Specifically, the above-mentioned first slot section 3111 and the second slot section 3112 are inclined in the same direction.

[0109] As shown in Figure 7 and Figure 2 , the hidden spoiler assembly is in an initial state, at this time, the column 100 is located at the bottom end, at this time, the front end of the spoiler plate 610 abuts against the front side of the column 100, the rear end of the spoiler plate 610 is higher than the first hinge 640, and there is a gap between the rear end of the spoiler plate 610 and the hatch 620, at this time, the guide sliding column 320 is located at the lower end of the first slot section 3111 or in the fourth slot section 3114.

[0110] The column 100 rises until the guide sliding column 320 slides to the upper end of the first slot section 3111, in this process, the first swing rod 310 rotates counterclockwise in the YZ plane and drives the hatch 620 to open, and the state of the hatch 620 after being opened is as shown in Figure 8 .

[0111] The column 100 continues to rise and drives the spoiler plate 610 and the pull rod 211 to move to the outside of the vehicle through the through hole 631, in this process, the guide sliding column 320 slides relative to the third slot section 3113 without rotating, as shown in Figure 9 , at this time, the guide sliding column 320 is located at the upper end of the third slot section 3113.

[0112] The column 100 continues to rise, the guide slide column 320 moves in the second slot section 3112, and drives the first swing lever 310 to rotate reversely (clockwise at this time) in the YZ plane and drives the hatch door 620 to close. At this time, the hatch door 620 is in close contact with the column 100 (designed according to specific requirements, and the subsequent exemplary description), and the state of the hatch door 620 after being closed is as shown in Figure 11 . In this process, the first limiting part 2111 and the first limiting part 220 abut, and the inclination angle adjustment of the spoiler 610 is performed (as shown in Figure 10 、 Figure 11 、 Figure 3 and Figure 4 ).

[0113] When the column 100 continues to rise to further adjust the inclination angle of the spoiler 610, the guide slide column 320 moves in the fifth slot section 3115. When the guide slide column 320 is located in the fifth slot section 3115, the guide slide column 320 only slides relative to the fifth slot section 3115 without rotating, the first swing lever 310 does not swing, and the hatch door 620 does not move. At this time, the column 100 can continue to rise and fall, for example, in the area "L" shown in Figure 10 , to perform specific inclination angle adjustment without worrying that the guide slide column 320 drives the first swing lever 310 to drive the hatch door 620 to link.

[0114] The actions of various components during the column 100 descending process are opposite to this, which will not be described in detail here.

[0115] In this way, the rapid opening or closing of the hatch door 620 can be achieved through the swing action of the first swing lever 310, and no collision with other components occurs. Compared with the multi-drive scheme, the reliability and stability are guaranteed, and even when the spoiler 610 is located outside the vehicle, the hatch door 620 can be closed, the wind resistance at the through hole 631 is reduced, and the wind noise is reduced.

[0116] As shown in Figure 1 、 Figure 5 、 Figure 6 、 Figure 13 and Figure 14 , optionally, the switch mechanism 300 further includes a first transmission box 340 and a second transmission box 350 connected in transmission. The first transmission box 340 is installed on the fixed frame 500, the first transmission box 340 includes a first rotating part 341 at the input end, the second transmission box 350 is arranged on the calibration side of the through hole 631 in the front-rear direction of the vehicle, and the second transmission box 350 includes a second transmission shaft 370 at the output end. The second transmission shaft 370 is drivingly connected with the hatch door 620;

[0117] The first rotating member 341 is coaxially arranged with the first shaft 520 and fixedly connected with the first swing rod 310 (not shown in the scheme); or, the first rotating member 341 is arranged at intervals with the first shaft 520, and the switch mechanism 300 further comprises a second swing rod 330, one end of the second swing rod 330 is movably connected with the first swing rod 310, and the other end of the second swing rod 330 is connected with the first rotating member 341.

[0118] The transmission mode between the first transmission box 340 and the second transmission box 350 can be gear transmission, belt transmission, chain transmission, etc. The other end of the second swing rod 330 is movably connected with the first swing rod 310, for example, rotatable connection, or can be arranged as a slidable and rotatable connection mode, thereby reducing the design difficulty, which can convert the rotation of the second swing rod 330 into the swing of the first swing rod 310 and drive the first rotating member 341 to rotate.

[0119] In the embodiment, the second transmission box 350 is arranged close to the calibration side of the through hole 631, and the first transmission box 340 is arranged on the fixed frame 500, so that the cabin door 620 can be directly driven to move by the first swing rod 310, the space occupation of the overall structure can be reduced on the basis of realizing power transmission, the space structure arrangement is facilitated, and the cabin door 620 can be supported to a certain extent to avoid excessive load on the edge of the through hole 631.

[0120] As shown in Figure 6 , further, the switch mechanism 300 further comprises a first transmission shaft 360, the first transmission box 340 and the second transmission box 350 adopt gear transmission, the first transmission box 340 and the second transmission box 350 themselves form a reversing transmission structure, and the two ends of the first transmission shaft 360 are connected with the first transmission box 340 and the second transmission box 350 respectively.

[0121] The gear transmission is not easy to slip, so that the repeatability of the movement of the cabin door 620 driven by the stand 100 can be guaranteed, the reliability is high, the number of position detection sensors can be reduced, and even no position detection sensor specially used for detecting the opening and closing state of the cabin door 620 is needed.

[0122] As shown in Figure 1 , Figure 15 , and Figure 16 , the switch mechanism 300 further comprises a plurality of multi-link mechanisms 380, and the plurality of multi-link mechanisms 380 are distributed at intervals in the transverse direction; in the front-rear direction, the multi-link mechanisms 380 are arranged on the calibration side of the through hole 631 in the vehicle, the multi-link mechanisms 380 are hingedly connected with the bottom of the cabin door 620 at multiple positions, and the second transmission shaft 370 is drivingly connected with the multi-link mechanisms 380.

[0123] Furthermore, the multi-link mechanism 380 includes a first link 381, a second link 382, ​​a first mounting base 383, and a base 384;

[0124] The first mounting base 383 is used to be set on the calibration side of the through hole 631. One end of the first connecting rod 381 and the second connecting rod 382 are respectively hinged to the first mounting base 383, and the other end of the first connecting rod 381 and the second connecting rod 382 are respectively hinged to one end of the seat body 384. The other end of the seat body 384 is used to be set at the bottom of the hatch 620. The first connecting rod 381, the second connecting rod 382, ​​the first mounting base 383 and the seat body 384 form a four-bar linkage mechanism. The second drive shaft 370 is drivenly connected to the first connecting rod 381.

[0125] For example, the second drive shaft 370 passes through the first mounting base 383 and is fixedly connected to the first connecting rod 381. The second drive shaft 370 drives the first connecting rod 381 to rotate around the first mounting base 383, thereby causing the hatch 620 to retract downward through the through hole 631 and move towards the calibration side (i.e., the front side).

[0126] In this way, compared to the method of directly installing the hatch 620 via a pivot, the space requirement in the vertical direction when the hatch 620 is opened or closed can be reduced, and the hatch 620 can be quickly withdrawn or closed.

[0127] like Figures 2 to 10 As shown, in order to further reduce the wind resistance at the through hole 631 when the spoiler 610 is located outside the vehicle, in an optional embodiment of the present invention, a cover 130 is provided on the column 100 near the upper end, and the swing structure 210 is housed in the cover 130 and extends to the outside of the cover 130 at both the upper and lower ends. When the spoiler 610 is located below the through hole 631 (i.e., in the initial state), the height of the front end of the spoiler 610 is lower than the height of the rear end of the spoiler 610, and the rear end face of the cover 130 is located behind the spoiler 610.

[0128] The hatch 620 includes a first hatch 621 and a second hatch 622, wherein the second hatch 622 is used to cover the area through which the cover 130 passes at the through hole 631;

[0129] The first hatch 621 and the second hatch 622 are pivotally connected to the through hole 631 on both sides in the front and rear directions, respectively. The first hatch 621 is driven to be connected to the switching mechanism 300.

[0130] The second hatch 622 is driven to connect with another switching mechanism 300, or a second reset element is provided at the pivot of the second hatch 622.

[0131] Specifically, when the first door 621 and the second door 622 are respectively driven by one switch mechanism 300, the second groove sections 3112 of the two switch mechanisms 300 are not the same, for example, the second groove section 3112 makes the second door 622 close to the rear end face of the cover 130 (this scheme is not shown).

[0132] Exemplarily, as shown in Figures 7 to 10 the bottom of the second door 622 is provided with a bent connecting plate, the other end of the connecting plate is connected with the outer plate of the back door 630 through a connecting shaft, a second reset member such as a torsion spring is arranged at the connecting shaft and respectively abuts against the outer plate and the connecting plate, under the action of the torsion spring, the second door 622 keeps the posture of covering the through hole 631 (for example, the outer plate is provided with a limiting block limiting the downward rotation of the second door 622), when the column 100 rises, the cover 130 pushes the second door 622 from below, the second door 622 abuts against the rear end face of the cover 130, when the column 100 descends and the cover 130 is retracted into the vehicle interior, under the action of the second reset member, the second door 622 is closed.

[0133] As shown in Figure 1 and Figure 2 another embodiment of the present application provides a vehicle comprising the above-mentioned hidden spoiler assembly.

[0134] The vehicle has the beneficial effects of the hidden spoiler assembly.
