A spoiler device and a vehicle

Abstract

The present invention provides a spoiler device and a vehicle. In the present invention, when the column rises to the first preset height, the limiting mechanism forms a swing limit for the swing rod mechanism, that is, the limiting mechanism restricts the upward translation of the swing rod mechanism along with the column but does not restrict the swing of the swing rod mechanism. At this time, the swing rod mechanism adapts to the height change of the column by swinging, and the height at the connection between the swing rod mechanism and the spoiler changes. The amplitude of this height change is inconsistent with the amplitude of the column height change, so that the spoiler rotates relative to the first hinge, realizing the adjustment of the tilt angle of the spoiler; when the column descends to the first preset height and during the lifting and lowering at a position lower than the first preset height, the limiting mechanism releases the swing limit for the swing rod mechanism. At this time, the swing rod mechanism rises and falls along with the column, and the attitude of the spoiler relative to the column can remain unchanged, and the spoiler can be moved to the required position by the lifting and lowering of the column. The present invention can reduce the number of drives and has high reliability.

Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and more particularly, to a spoiler device and a vehicle. Background Art

[0002] During the driving of an automobile, due to the shape and structure characteristics of the automobile itself, an upward lift force will be generated when the automobile is driving. When the driving speed of the automobile is relatively high, the adhesion between the automobile and the ground decreases. In order to alleviate the adverse effects of the lift force on the driving stability of the automobile as much as possible, designers often start from the shape of the automobile and perform specific optimizations on the shape of the automobile to reduce the generated lift force.

[0003] In the related art, by configuring a spoiler device such as a rear wing on the vehicle, when air flows through the spoiler of the spoiler device, the pressure difference between the upper and lower surfaces of the spoiler will generate a downward-acting pressure to help the automobile stick to the ground and improve the adhesion ability of the vehicle to the ground. However, most of the spoiler devices on current vehicles are in a fixed form, and the inclination angle of the spoiler for generating the downward pressure is fixed, which is difficult to meet the adjustment requirements of the inclination angle of the spoiler; a small part of the spoiler devices are equipped with multiple driving members such as telescopic cylinders, and the height adjustment or inclination angle adjustment of the spoiler is achieved through the lifting cooperation of multiple telescopic cylinders. The relatively large number of driving members makes the adjustment of the spoiler more complicated, and the multiple driving members are easily damaged due to reasons such as vehicle vibration, resulting in low reliability. Summary of the Invention

[0004] The present invention aims to solve, to a certain extent, the problem of low reliability of the spoiler device caused by multiple driving members driving the spoiler to act in the related art.

[0005] In a first aspect, the present invention provides a spoiler device, including a spoiler, a column, a swing rod mechanism, a limiting mechanism, and a driving mechanism;

[0006] The upper end of the column is hinged to the spoiler through a first hinge member, and the driving mechanism is used to drive the column to move up and down in the vertical direction;

[0007] The swing rod mechanism is hinged to the column, and the swing rod mechanism is used to be movably connected to the spoiler, and the connection position is spaced apart from the first hinge member in a direction forming an angle with the vertical direction;

[0008] The limiting mechanism is used to form a swing limit for the swing rod mechanism when the column rises to a first preset height. When the swing limit is formed at the swing rod mechanism, the swing rod mechanism is used to convert the lifting movement of the column into the rotation of the spoiler through swinging.

[0009] Optionally, one end of the swing rod mechanism is hinged to the spoiler through a second hinge member;

[0010] A first limiting structure is provided on the swing rod mechanism. The swing rod mechanism includes a swing rod, and the swing rod is hinged to the column.

[0011] The limiting mechanism includes a first limiting member and an elastic member. The first limiting member is fixedly arranged above the first limiting structure. When the column rises to the first preset height, the first limiting member abuts against the first limiting structure, and the first limiting structure is configured to swing relative to the first limiting member. One end of the elastic member is connected to the spoiler, and the other end is connected to the swing rod mechanism or the column.

[0012] Optionally, the swing rod mechanism further includes a first connecting rod and a second connecting rod.

[0013] The upper end of the first connecting rod is hinged to the spoiler through the second hinge member, and the lower end of the first connecting rod is hinged to one end of the swing rod.

[0014] The upper end of the second connecting rod is hinged to the other end of the swing rod, and the first limiting structure is arranged at the lower end of the second connecting rod.

[0015] The middle part of the swing rod is hinged to the column.

[0016] Optionally, a second limiting structure is further provided on the second connecting rod, and the limiting mechanism further includes a second limiting member arranged on the column. The second limiting member is configured to move up and down with the column.

[0017] The second limiting member includes a first abutting portion for abutting against the second limiting structure above and a chute. The chute is located below the first abutting portion and extends in the up-and-down direction to the first abutting portion.

[0018] The second limiting structure is located below the first limiting structure. A guide sliding cylinder is arranged on the second limiting structure, and the axis of the guide sliding cylinder is parallel to the rotation axis of the swing rod.

[0019] The guide sliding cylinder is slidably arranged in the chute, and the chute restricts the guide sliding cylinder from detaching from the second limiting member.

[0020] Optionally, the first limiting member is located on the movement path of the column, and a through hole is provided on the first limiting member. The column passes through the through hole.

[0021] The first limiting structure includes a convex block arranged on the second connecting rod close to the column side, and the convex block extends below the first limiting member.

[0022] Optionally, one end of the elastic member is connected to the hinge joint between the first connecting rod and the spoiler, and the other end is connected to the hinge joint between the second connecting rod and the swing rod.

[0023] Optionally, both ends of the first connecting rod are located on different sides of the column.

[0024] The first connecting rod includes a first rod segment hinged to the spoiler and a second rod segment hinged to the swing rod. The first rod segment and the second rod segment are arranged at a first included angle, and the opening of the first included angle faces the first hinge member.

[0025] Optionally, the spoiler device further includes a mounting frame. The column and the mounting frame are slidably connected in the up-and-down direction. The driving mechanism includes a driving member and a screw transmission member. The driving member is drivingly connected to the screw transmission member, and the screw transmission member is in screw transmission connection with the column.

[0026] Optionally, the column includes a column body and a slider provided at the bottom of the column body. A guide rail is provided on the mounting frame, and the slider is slidably connected to the guide rail. The screw transmission member includes a lead screw, and the lead screw passes through the slider and is in screw transmission connection with the slider.

[0027] The upper end of the lead screw is rotatably mounted on the mounting frame through a bearing, or the lower end of the column body is provided with a hollow structure for accommodating one end of the lead screw passing through the slider.

[0028] Optionally, when the column descends to be lower than the first preset height, the column is used for lifting to extend or retract the spoiler to or from the accommodation part of the vehicle. When the spoiler is accommodated in the accommodation part, the upper surface of the spoiler is flush with the outer surface of the vehicle at the accommodation part.

[0029] In a second aspect, the present invention provides a vehicle including the spoiler device as described in the first aspect above.

[0030] Compared with the related prior art, in the spoiler device and the vehicle of the present invention, the column is driven to rise and fall by a driving mechanism. When the column rises to a first preset height, the limiting mechanism forms a swing limit on the swing rod mechanism, that is, the limiting mechanism restricts the upward translation of the swing rod mechanism along with the column but does not restrict the swing of the swing rod mechanism. At this time, the swing rod mechanism adapts to the height change of the column by swinging, and the height at the connection between the swing rod mechanism and the spoiler changes. The amplitude of this height change is inconsistent with the amplitude of the height change of the column, so that the spoiler rotates relative to the first hinge, realizing the adjustment of the tilt angle of the spoiler; when the column descends to the first preset height and rises and falls at a position lower than the first preset height, the limiting mechanism releases the swing limit on the swing rod mechanism. At this time, the swing rod mechanism rises and falls with the column, and the attitude of the spoiler relative to the column can remain unchanged. The spoiler can be moved to the required position by raising and lowering the column, for example, moving to be flush with the outer surface of the vehicle. The present invention can realize the overall height adjustment of the spoiler and the swing rod mechanism by raising and lowering the column before the column rises to the first preset height. After the column rises to the first preset height, the tilt angle adjustment of the spoiler can be realized by raising and lowering the column, which can avoid using multiple drives to realize the height adjustment and tilt angle adjustment of the spoiler, reduce the number of drives, thereby reducing the safety risk caused by drive damage, with high reliability and strong practicability. The tilt angle of the spoiler can also be adjusted according to the needs of vehicle driving, such as the need to increase vehicle adhesion or the need for braking, etc., and the controllability is relatively high.

Detailed implementation manners

[0043] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings.

[0044] In the attached drawings, the Z-axis represents the vertical direction, that is, the up and down position. The positive direction of the Z-axis (i.e., the direction pointed by the arrow of the Z-axis) represents up, and the negative direction of the Z-axis (i.e., the direction opposite to the positive direction of the Z-axis) represents down. The X-axis in the attached drawings represents the horizontal direction and is specified as the left and right position. The positive direction of the X-axis (i.e., the direction pointed by the arrow of the X-axis) represents the right side, and the negative direction of the X-axis (i.e., the direction opposite to the positive direction of the X-axis) represents the left side. The Y-axis in the attached drawings represents the front and back position. The positive direction of the Y-axis (i.e., the direction pointed by the arrow of the Y-axis) represents the front side, and the negative direction of the Y-axis (i.e., the direction opposite to the positive direction of the Y-axis) represents the back side. At the same time, it should be noted that the above-mentioned meanings represented by the Z-axis, Y-axis, and X-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0045] As Figures 1 to 5 shown, in an embodiment of the present invention, a spoiler device is provided, which includes a spoiler 100, a column 200, a swing rod mechanism 300, a limiting mechanism 400, and a driving mechanism 500;

[0046] The upper end of the column 200 is hinged to the spoiler 100 through a first hinge 010, and the driving mechanism 500 is used to drive the column 200 to move up and down;

[0047] The swing rod mechanism 300 is hinged to the column 200. The swing rod mechanism 300 is used to be movably connected to the spoiler 100, and the connection positions are spaced apart in a direction forming an angle with the up and down direction with respect to the first hinge 010;

[0048] The limiting mechanism 400 is used to form a swing limit for the swing rod mechanism 300 when the column 200 rises to a first preset height. When a swing limit is formed at the swing rod mechanism 300, the swing rod mechanism 300 is used to convert the up and down movement of the column 200 into the rotation of the spoiler 100 through swinging.

[0049] Specifically, the swing rod mechanism 300 includes a swing rod 310, and the swing rod 310 is hinged to the column 200.

[0050] Thus, for the flow disturbing device of the present invention, the driving mechanism 500 drives the column 200 to lift. When the column 200 rises to the first preset height, the limiting mechanism 400 forms a swing limit for the swing rod mechanism 300, that is, the limiting mechanism 400 restricts the upward translation of the swing rod mechanism 300 along with the column 200 but does not restrict the swing of the swing rod mechanism 300. At this time, the swing rod mechanism 300 adapts to the height change of the column 200 by swinging, and the height at the connection between the swing rod mechanism 300 and the spoiler 100 changes. The amplitude of this height change is inconsistent with the amplitude of the height change of the column 200, so that the spoiler 100 rotates relative to the first hinge 010, realizing the adjustment of the tilt angle of the spoiler 100; when the column 200 descends to the first preset height and during the lifting and lowering at a position lower than the first preset height, the limiting mechanism 400 releases the swing limit for the swing rod mechanism 300. At this time, the swing rod mechanism 300 rises and falls along with the column 200, and the attitude of the spoiler 100 relative to the column 200 can remain unchanged. The spoiler 100 can be moved to the required position by the lifting and lowering of the column 200, such as moving to be flush with the outer surface of the vehicle (subsequent explanations will be based on this case), or moving to be stored inside the vehicle. The present invention can realize the overall height adjustment of the spoiler 100 and the swing rod mechanism 300 by the lifting and lowering of the column 200 before the column 200 rises to the first preset height. After the column 200 rises to the first preset height, the tilt angle adjustment of the spoiler 100 can be realized by the lifting and lowering of the column 200, which can avoid using multiple drives to realize the height adjustment and tilt angle adjustment of the spoiler 100, reduce the number of drives, and thus reduce the safety risk caused by drive damage, with high reliability and strong practicability. The tilt angle of the spoiler 100 can also be adjusted according to the driving needs of the vehicle, such as the need to increase the adhesion ability of the vehicle or the need for braking, etc., and the controllability is relatively high.

[0051] As Figures 1 to 5 shown, optionally, one end of the swing rod mechanism 300 is hinged to the spoiler 100 through a second hinge 020, and the distribution directions of the first hinge 010 and the second hinge 020 are arranged at an angle with the up and down direction;

[0052] A first limiting structure 340 is arranged on the swing rod mechanism 300. The swing rod mechanism 300 includes a swing rod 310, and the swing rod 310 is hinged to the column 200;

[0053] The limiting mechanism 400 includes a first limiting member 410 and an elastic member 420. The first limiting member 410 is fixedly arranged above the first limiting structure 340. When the column 200 rises to the first preset height, the first limiting member 410 abuts against the first limiting structure 340, and the first limiting structure 340 is used for swinging relative to the first limiting member 410;

[0054] The elastic member 420 is respectively connected to two of the spoiler 100, the swing rod mechanism 300 and the column 200.

[0055] Preferably, one end of the elastic member 420 is connected to the spoiler 100, and the other end is connected to the swing rod mechanism 300 or the column 200.

[0056] Specifically, when the column 200 rises to the first preset height (such as Figure 3 ), the first limiting structure 340 and the first limiting member 410 are in a just-abutting state. That is to say, if the column 200 descends at this time, the first limiting member 410 releases the limitation on the first limiting structure 340.

[0057] When the column 200 moves upward between the first preset height and the second preset height (such as Figure 4 ), the elastic potential energy of the elastic member 420 increases, and the swing rod 310 rotates relative to the column 200 to drive the spoiler 100 to rotate around the first hinge 010 in the first direction;

[0058] When the column 200 moves downward between the first preset height and the second preset height, the elastic potential energy of the elastic member 420 decreases, and the first limiting member 410 remains in the abutting state with the first limiting structure 340. The swing rod 310 rotates relative to the column 200 to drive the spoiler 100 to rotate around the first hinge 010 in the reverse direction of the first direction; wherein, the second preset height is higher than the first preset height, and the second preset height is the upper limit position of the column 200.

[0059] It should be noted that the swing rod 310 of the swing rod mechanism 300 is rotatably connected to the column 200 through the third hinge 030. The third hinge 030 is located below the first hinge 010. The swing rod mechanism 300 can rotate around the third hinge 030. When the first limiting member 410 abuts against the first limiting structure 340, the swing rod 310 is used to convert the lifting movement of the column 200 into a rotation relative to the column 200. The swing rod mechanism 300 is linked and transmits the rotation of the swing rod 310 to the second hinge 020. Thus, both the second hinge 020 and the spoiler 100 move relative to the first hinge 010. On this basis, the structure of the swing rod mechanism 300 is not limited and will be described in detail later.

[0060] Thus, for the spoiler device of the present invention, the driving mechanism 500 drives the column 200 to lift. When the column 200 rises to the first preset height, the first limiting member 410 abuts against the first limiting structure 340 from above, which can form a limit on the upward translation of the first limiting structure 340. This limit will be transmitted to the swing rod 310 of the swing rod mechanism 300, so that the upward translation of the swing rod 310 is restricted (translation means that each point on the swing rod 310 moves along a straight line and the movement directions are exactly the same); further, the first limiting structure 340 is arranged to be swingable relative to the first limiting member 410 when abutting against the first limiting member 410. This swingability is transmitted to the swing rod 310 of the swing rod mechanism 300 and is manifested as the swing rod 310 can rotate relative to the column 200. Thus, when the column 200 continues to rise from the first preset height, the swing rod 310 rotates relative to the column 200, and then the end of the swing rod mechanism 300 for connecting to the spoiler 100 will rotate, so that the spoiler 100 will rotate around the first hinge 010, thereby realizing the adjustment of the tilt angle of the spoiler 100; in addition, an elastic member 420 connected to the swing rod mechanism 300 is provided. When the column 200 stays at any height higher than the first preset height (for example, stays at the second preset height, the upper limit position), under the action of the elastic member 420, the first limiting structure 340 maintains the abutting state with the first limiting member 410. As long as the column 200 does not move, the relative pose of the swing rod mechanism 300 relative to the column 200 is kept unchanged by the acting force of the elastic member 420, so that the tilt angle of the spoiler 100 remains unchanged, and its stability is high. The present invention can realize the overall height adjustment of the spoiler 100 and the limiting mechanism 400 by the lifting of the column 200 before the column 200 rises to the first preset height, and after the column 200 rises to the first preset height, the tilt angle of the spoiler 100 can be adjusted by the lifting of the column 200. It can avoid using multiple drives to realize the height adjustment and tilt angle adjustment of the spoiler 100, reduce the number of drives, thereby reducing the safety risk caused by drive damage, with high reliability and strong practicability. The tilt angle of the spoiler 100 can be adjusted according to vehicle driving needs, such as the need to increase vehicle adhesion or the need for braking, etc., and the controllability is relatively high.

[0061] It should be understood that in specific use, the spoiler device can be an external structure (i.e., before use, the spoiler 100 is exposed. For example, the spoiler 100 is accommodated in the accommodation part 710 provided in the housing of the rear door 700), or it can be an internal structure (i.e., when not in use, the spoiler device is retracted into the vehicle interior to avoid exposure). In both cases, the initial inclination angle of the spoiler 100 can be the same. For example, the initial inclination angle of the spoiler 100 enables it to move to be flush with the outer surface of the vehicle (at this time, the heights of the front and rear ends of the spoiler 100 can be substantially the same). At this time, when the column 200 rises to the first preset height and continues to rise, it is necessary to raise the height of the rear end of the spoiler 100, so as to adjust the inclination angle of the spoiler 100 (such as Figure 3 , Figure 4 ).

[0062] The initial inclination angles can be different. For example, in the initial state of the internal structure, the height of the front end of the spoiler 100 is lower than the height of the first hinge 010. When the initial inclination angles are different, the specific positions and structures of the first hinge 010, the second hinge 020, and even the swing rod mechanism 300 are determined according to the specific installation and use requirements of the spoiler device.

[0063] Specifically, when the heights of the front end and the rear end of the spoiler 100 are substantially the same in the initial state, the inclination angle of the spoiler 100 relative to the horizontal plane (i.e., the XY plane) is, for example, zero. When the column 200 rises to the first preset height and continues to rise, the swing rod mechanism 300 drives the rear end of the spoiler 100 to rise relative to the column 200, and the inclination angle of the spoiler 100 relative to the horizontal plane increases. At this time, the spoiler device can be external or internal (subsequently referred to as Case 1).

[0064] Exemplarily (not shown in this schematic diagram), the spoiler device is an external structure, and in the initial state, the spoiler 100 maintains a state where the heights at the front end and the rear end are substantially the same (for example, it can be maintained by gravity and the second abutting structure. For example, the gravity of the spoiler 100 is arranged closer to the rear end compared to the front end. Under the action of gravity, the spoiler 100 abuts against the second abutting structure located below the spoiler 100 at the first hinge 010, and the second abutting structure is arranged on the column 200). The swing rod mechanism 300 may only include a swing rod 310. The middle position of the swing rod 310 is hinged to the column 200 through a third hinge 030. A first limiting structure 340 is arranged at the front end of the swing rod 310. A connecting portion extending downward is arranged at the rear of the first hinge 010 on the lower surface of the spoiler 100. The lower end of the connecting portion is connected to the rear end of the swing rod 310 through a second hinge 020. The elastic member 420 may be a tension spring, and both ends of the tension spring are connected to the swing rod 310 and the spoiler 100 respectively. For example, the upper end is connected to the connecting portion of the spoiler 100, and the lower end is connected to the front end of the swing rod 310. In this way, when the column 200 moves up and down below the first preset height, under the action of the tension spring and the second abutting structure, the initial position of the swing rod 310 remains unchanged, so that the first limiting member 410 can abut against the first limiting structure 340. When the column 200 rises to the first preset height and continues to rise, since the front end of the swing rod 310 cannot move upward horizontally, the column 200 will drive the swing rod 310 to rotate, so that the rear end of the swing rod 310 moves upward, and thus the spoiler 100 rotates around the first hinge point and the height of the rear end rises, so that the inclination angle of the spoiler 100 relative to the horizontal plane increases.

[0065] When the spoiler device is internal and the height of the front end of the spoiler 100 is much lower than the height of the first hinge 010 in the initial state, its inclination angle relative to the horizontal plane (i.e., the XY plane) reaches the maximum. When the column 200 rises to the first preset height and continues to rise, the rear end of the spoiler 100 is driven to descend relative to the height of the column 200 through the swing rod mechanism 300, and the inclination angle of the spoiler 100 relative to the horizontal plane decreases (subsequently referred to as Case 2).

[0066] Exemplarily (not shown in this schematic diagram), the swing rod mechanism 300 may only include a swing rod 310. The front end of the swing rod 310 is hinged to the column 200 through a third hinge 030. A first limiting structure 340 is provided at the rear end of the swing rod 310. A connecting portion extending downward is provided on the lower surface of the spoiler 100 behind the first hinge 010. The lower end of the connecting portion is hinged to the middle position of the swing rod 310 through a second hinge 020. Both ends of a tension spring are connected to the swing rod 310 and the spoiler 100 respectively. For example, the upper end is connected to the front end portion of the spoiler 100, and the lower end is connected to the middle position of the swing rod 310. At this time, a third abutting portion may be provided at the front end of the column 200, and the third abutting portion abuts against the lower surface of the spoiler 100 under the drive of, for example, the tension spring, so as to lock the position of the spoiler 100 in the initial state. At this time, when the column 200 rises to the first preset height and continues to rise, since the rear end of the swing rod 310 cannot move upward horizontally, the column 200 will drive the swing rod 310 to rotate, so that the front end of the swing rod 310 moves upward, and thus the spoiler 100 rotates around the first hinge 010 and the height of the rear end decreases, so that the inclination angle of the spoiler 100 relative to the horizontal plane decreases.

[0067] In this specification, subsequently, the content of the present invention will be described by taking Case 1, that is, in the initial state, the heights of the front end and the rear end of the spoiler 100 are basically the same, and the spoiler device is an external structure as an example.

[0068] As Figures 1 to 5 shown, optionally, the swing rod mechanism 300 further includes a second connecting rod 330. The upper end of the second connecting rod 330 is hinged to the swing rod 310 through a fifth hinge 050, and the first limiting structure 340 is provided at the lower end of the second connecting rod 330.

[0069] At this time, when the first limiting structure 340 is limited by the first limiting member 410, the second connecting rod 330 swings within a small range, and the swing rod 310 also swings, so as to realize the angle adjustment of the spoiler 100.

[0070] This method can reduce the requirement for the position height of the first limiting member 410, can avoid the difficulty of position setting caused by the excessive height of the first limiting member 410, and has a compact space structure and strong practicability.

[0071] As Figures 1 to 5 shown, optionally, the swing rod mechanism 300 further includes a first connecting rod 320. The upper end of the first connecting rod 320 is hinged to the spoiler 100 through a second hinge 020, and the lower end of the first connecting rod 320 is hinged to the swing rod 310 through a fourth hinge 040.

[0072] In this way, it is possible to avoid directly hinging the spoiler 100 to the swing rod 310, and to a certain extent, reduce the structural limitation on the spoiler 100.

[0073] As shown Figures 1 to 2 in the figure, the subsequent description of the swing rod mechanism 300 includes the above-mentioned swing rod 310, the first connecting rod 320, and the second connecting rod 330 will be given.

[0074] Optionally, in the length direction of the swing rod 310, the fourth hinge 040 and the fifth hinge 050 are respectively located on both sides of the third hinge 030.

[0075] That is to say, at this time, the upper end of the first connecting rod 320 is hinged to the spoiler 100 through the second hinge 020, and the lower end of the first connecting rod 320 is hinged to one end of the swing rod 310; the upper end of the second connecting rod 330 is hinged to the other end of the swing rod 310, and the first limiting structure 340 is arranged at the lower end of the second connecting rod 330; the middle of the swing rod 310 is hinged to the column 200.

[0076] In this way, compared with the way that both the fourth hinge 040 and the fifth hinge 050 are located on the same side of the third hinge 030, in this solution, the fourth hinge 040 and the fifth hinge 050 are respectively located on different sides of the third hinge 030, which is convenient for spatial layout, for example, it is convenient to arrange the layout of the tension spring, etc.; in addition, when the column 200 rises to the first preset height and continues to rise, the fourth hinge 040 can obtain a rising distance relative to the fifth hinge 050 to realize the adjustment of the inclination angle of the spoiler 100, and this rising distance can be adjusted according to the ratio of the distances from the fourth hinge 040 and the fifth hinge 050 to the third hinge 030 respectively.

[0077] Furthermore, the two ends of the first connecting rod 320 are respectively located on different sides of the column 200.

[0078] Exemplarily, as shown Figures 1 to 4 in the figure, at this time, the fourth hinge 040 can be arranged in front of the column 200, while the second hinge 020, the fifth hinge 050, and the first limiting member 410 can all be arranged behind the column 200, reducing the limitation that the second hinge 020 and the fifth hinge 050 must be located on the same side of the column 200.

[0079] At this time, further, the first connecting rod 320 includes a first rod segment 321 hinged to the spoiler 100 and a second rod segment 322 hinged to the swing rod 310. The first rod segment 321 and the second rod segment 322 are arranged at a first included angle, and the opening of the first included angle faces the first hinge 010. This can avoid the interference between the first connecting rod 320 and the first hinge 010 during the movement process, and the spatial structure is compact and the reliability is high.

[0080] As shown Figure 2As shown, exemplarily, in the above embodiments, both the swing rod 310 and the first connecting rod 320 can be provided in two corresponding to the column 200. The two swing rods 310 are respectively arranged on both sides of the column 200 in the X-axis direction (i.e., the vehicle width direction). The first ends of the two swing rods 310 (taking the rear end in the figure as an example) are connected by a fifth hinge 050. The second end of the swing rod 310 is hingedly connected to the first connecting rod 320 through a fourth hinge 040. The fourth hinge 040 can be respectively hingedly connected to the second ends of the two swing rods 310.

[0081] Optionally, as Figures 1 to 4 shown, it shows the case where the elastic member 420 is a tension spring. One end of the tension spring is connected to the spoiler 100, and the other end is connected to the swing rod 310.

[0082] Exemplarily, when the spoiler device is Figure 3 the external structure shown, the shown tension spring is located behind the column 200. One end of the tension spring is connected to the hinge joint between the first connecting rod 320 and the spoiler 100, and the other end is connected to the hinge joint between the second connecting rod 330 and the swing rod 310. The figure shows the case where both the fifth hinge 050 and the second hinge 020 are hinge shafts, and the upper end of the tension spring is connected to the second hinge 020, and the lower end is connected to the fifth hinge 050.

[0083] At this time, when the column 200 is at Figure 3 the first preset height shown and Figure 4 any position between the second preset height shown, under the pulling force of the tension spring, the first limiting structure 340 and the first limiting member 410 remain in contact. At this time, the first limiting structure 340 can be regarded as a hinge. At this time, the column 200, the spoiler 100, the first connecting rod 320, the swing rod 310, the second connecting rod 330, and the mounting bracket 600 (described later) form a multi-link structure. When the height of the column 200 remains unchanged, the multi-link structure has only one degree of freedom, and this degree of freedom is restricted by the tension spring. Specifically, when the rear end of the spoiler 100 has a tendency to move downward, the second hinge 020 and the fourth hinge 040 have a tendency to move downward, the fifth hinge 050 has a tendency to move upward, and the first limiting structure 340 has a tendency to move upward. However, the first limiting structure 340 is in contact with the first limiting member 410. Therefore, the rear end of the spoiler 100 cannot move downward. When the rear end of the spoiler 100 has a tendency to move upward, due to the pulling force of the tension spring and the contact between the first limiting structure 340 and the first limiting member 410, the upward movement of the rear end of the spoiler 100 is restricted. Thus, for any height of the column 200 between the first preset height and the second preset height, the spoiler 100 has a corresponding tilt angle, and continuous and large-range adjustment of the tilt angle of the spoiler 100 can be achieved.

[0084] As Figures 1 to 7 shown, optionally, the limiting mechanism 400 further includes a second limiting member 430 disposed on the column 200, and the second limiting member 430 is used to lift and lower along with the column 200;

[0085] A second limiting structure 350 is further disposed on the second link 330. The second limiting structure 350 and the first limiting structure 340 are spaced apart in the up-down direction, and the second limiting member 430 is used to abut against the second limiting structure 350 from above.

[0086] Specifically, before the column 200 rises to the first preset height, the second limiting member 430 is used to keep abutting against the second limiting structure 350 from above under the elastic potential energy of the elastic member 420;

[0087] When the column 200 rises to the first preset height and continues to rise, the second link 330 swings relative to the first limiting member 410 and the second limiting member 430, and moves in the up-down direction relative to the second limiting member 430.

[0088] That is to say, in the initial state, the second limiting member 430 abuts against the second limiting structure 350. Exemplarily, at the initial position and the first preset height, the pulling force of the tension spring is the same. In the initial state, the position of the spoiler 100 is also locked. During the process of the column 200 rising to the first preset height, the pose of the spoiler 100 remains unchanged. When the column 200 continues to rise from the first preset height, the first limiting structure 340 abuts against the first limiting member 410, and the second limiting member 430 releases the abutment against the second limiting structure 350 in the up-down direction. Thus, the second link 330 can swing relative to the first limiting member 410 and the second limiting member 430 to adapt to the swing of the second link 330 caused by the adjustment of the tilt angle of the spoiler 100.

[0089] Further, as Figures 5 to 7 shown, the second limiting member 430 includes a first abutting portion 431 for abutting against the second limiting structure 350 and a sliding groove 432. The sliding groove 432 is located below the first abutting portion 431 and extends in the up-down direction to the first abutting portion 431;

[0090] The second limiting structure 350 is located below the first limiting structure 340. The second limiting structure 350 includes a guide sliding cylinder 360, and the axis of the guide sliding cylinder 360 is parallel to the rotation axis of the swing rod 310;

[0091] The guide sliding cylinder 360 is slidably disposed in the sliding groove 432, and the guide sliding cylinder 360 is restricted from separating from the second limiting member 430 through the sliding groove 432.

[0092] In this way, the separation of the second limiting structure 350 and the second limiting member 430 in the front-rear direction can be avoided.

[0093] Further, as Figure 7 , the first limiting member 410 is located on the movement path of the column 200. A through hole 411 is provided on the first limiting member 410, and the column 200 passes through the through hole 411; the first limiting structure 340 includes a convex block provided on the side of the second connecting rod 330 close to the column 200, and the convex block extends below the first limiting member 410. The second limiting structure 350 can also be provided as a convex block, and the dimension of the second limiting structure in the front-rear direction is larger than that of the first limiting structure 340 in the front-rear direction, which will not be elaborated here

[0094] As Figure 5 shown, in an alternative embodiment of the invention, the spoiler device further includes a mounting bracket 600. The column 200 is slidably connected to the mounting bracket 600 in the up-down direction. The driving mechanism 500 includes a driving member 510 and a screw transmission member 520. The driving member 510 is drivingly connected to the screw transmission member 520, and the screw transmission member 520 is in screw transmission connection with the column 200.

[0095] Optionally, the driving mechanism 500 includes a driving member 510 and a screw transmission member 520. The driving member 510 is drivingly connected to the screw transmission member 520, and the screw transmission member 520 is in screw transmission connection with the column 200.

[0096] As Figure 2 shown, exemplarily, the driving member 510 may include a motor 511 and a worm and worm gear reducer 512. The housing of the worm and worm gear reducer 512 is mounted on the mounting bracket 600. The motor 511 is mounted on the housing of the worm and worm gear reducer 512, and the motor 511 is drivingly connected to the worm and worm gear reducer 512. The output end of the worm and worm gear reducer 512 is connected to the screw transmission member 520, thereby driving the screw transmission member 520 to rotate.

[0097] Thus, the driving member 510 drives the screw transmission member 520 to rotate, and the screw transmission member 520 is in screw transmission connection with the column 200, thereby converting the rotational motion of the screw transmission member 520 into the sliding of the column 200 on the guide rail 610. The screw transmission method has better transmission smoothness, so that the column 200 slides smoothly in the up-down direction, and further the angle adjustment of the spoiler 100 is relatively smooth.

[0098] Optionally, the column 200 includes a column body 210 and a slider 220 provided at the bottom of the column body 210. A guide rail 610 is provided on the mounting bracket 600, and the slider 220 is slidably connected to the guide rail 610; the screw transmission member 520 includes a lead screw, and the lead screw passes through the slider 220 and is in screw transmission connection with the slider 220;

[0099] The upper end of the lead screw is rotatably mounted on the mounting bracket 600 through a bearing.

[0100] Exemplarily, both ends of the lead screw are rotatably mounted on the mounting bracket 600 through bearings. That is to say, bearing connection parts for connecting the bearings are provided at both ends of the lead screw, and the mounting bracket 600 can form a better rotational support for the lead screw. In this case, the connection between the column body 210 and the slider 220 is staggered from the lead screw to avoid interference of the column body 210 with the lead screw (not shown in the figure).

[0101] Different from the above solution where the upper end of the lead screw is rotatably mounted on the mounting bracket 600, optionally, the lower end of the column body 210 is provided with a hollow structure for accommodating one end of the lead screw passing through the slider 220.

[0102] In this case, the installation structure of the threaded transmission member 520 can be simplified, and the weight and space occupation can be reduced.

[0103] It should be understood that the slider 220 can be detachably connected to the column body 210, so as to facilitate the processing of the slider 220. Of course, it can also be set as an integral connection.

[0104] The above first limiting member 410 can be arranged on the mounting bracket 600, and the second limiting member 430 can be integrated on the slider 220, which will not be elaborated here.

[0105] In an alternative embodiment of the present invention, when the column 200 descends to a height lower than the first preset height, that is, when the first limiting structure 340 is separated from the first limiting member 410, the column 200 is used for lifting to extend or retract the spoiler 100 to or from the accommodating portion 710 of the vehicle. When the spoiler 100 is accommodated in the accommodating portion 710, the upper surface of the spoiler 100 is flush with the outer surface of the vehicle at the accommodating portion 710.

[0106] As Figures 8 to 10 shown, taking the spoiler device as a rear spoiler device as an example, the rear door 700 of the vehicle is provided with a communication port for the column 200, the swing rod mechanism 300, etc. to pass through, and an accommodating portion 710 for accommodating the spoiler 100 at a position close to the rear of the vehicle. The communication port is communicated with the accommodating portion 710. The mounting bracket 600 is installed inside the rear door 700 itself, or on the side of the rear door 700 facing the internal space of the trunk.

[0107] "Flush" should be understood as that in the longitudinal section of the vehicle (parallel to the YZ plane), the line contour of the upper surface of the spoiler 100 and the surface contour line of the rear door 700 are basically smoothly transitioned, so as to reduce the wind resistance at the accommodating portion 710 to a certain extent.

[0108] As Figure 1 、 Figure 2 and Figure 8As shown, when the column 200 is in the initial position, the spoiler 100 is received in the receiving portion 710. At this time, the upper surface of the spoiler 100 and the outer surface of the rear door 700 are in the same plane. Before the column 200 rises to the first preset height, the spoiler 100 and the swing rod mechanism 300 translate with the column 200.

[0109] As Figure 3 , Figure 5 and Figure 9 shown, the driving mechanism 500 drives the column 200 to rise until the column 200 is at the first preset height. At the first preset height, the swing rod 310 is just in the state of starting to rotate. At this time, the spoiler 100 is located above the rear door 700 and there is a height difference between the spoiler 100 and the rear door 700, and this height difference can be used for adjusting the tilt angle of the spoiler 100.

[0110] As Figure 4 and Figure 10 shown, the driving mechanism 500 continues to drive the column 200 to rise until the column 200 is at the second preset height. At the second preset height, the swing rod 310 is in the state after rotation. The second preset height is the upper limit position of the rising movement of the column 200. At this time, the tilt angle of the spoiler 100 reaches the maximum.

[0111] Furthermore, the first hinge 010 is located in front of the second hinge 020.

[0112] It should be understood that when the spoiler 100 is in the working state, the height of the rear end is significantly higher than the height of the front end. By setting the first hinge 010 at the front end of the second hinge 020, and in the case of the same height and tilt angle, setting the first hinge 010 in front of the second hinge 020 can reduce the height requirement for the second preset height of the column 200, and thus, to a certain extent, reduce the lifting stroke requirement of the column 200.

[0113] Furthermore, the distance from the first hinge 010 to the front end face of the spoiler 100 (defined as the first distance) is less than the distance from the first hinge 010 to the rear end face of the spoiler 100 (defined as the second distance). That is, the front end face of the spoiler 100 is arranged closer to the first hinge 010 compared to the rear end face.

[0114] The first distance and the second distance are illustrated exemplarily as follows. A first plane (the first plane is parallel to the YZ plane) passing through the center line of the first hinge 010 (taking it as an example of the first hinge axis), for example, passing through the center of the first hinge axis and perpendicular to the first hinge axis, is defined. The intersections of the front and rear ends of the upper surface of the spoiler 100 with the first plane are respectively defined as the first point and the second point. When the heights of the first point and the second point are basically the same, a first connection line is obtained by connecting the first point and the second point. A second plane perpendicular to the first connection line is made through the center line of the first hinge axis. At this time, the distance from the first point to the second plane can be approximately the first distance, and the distance from the second point to the second plane can be approximately the second distance. The first distance can be, for example, 0.6 - 0.98 times the second distance, such as 0.65 - 0.9 times, 0.7, 0.8 times.

[0115] At this time, the area of the part of the upper surface of the spoiler 100 located in front of the second plane is relatively small. As a result, the acting point of the resultant force of the negative lift (i.e., the downward pressure) generated by the passing air finally is located behind the first pin shaft. Thus, under the action of the negative lift, the first limiting structure 340 remains in contact with the first limiting member 410, which can reduce the elastic force requirement for the elastic member 420 and has high reliability.

[0116] On the contrary, in the front - rear direction, if the acting point of the downward pressure received by the spoiler 100 is located in front of the first pin shaft, then under the action of the negative lift, the first limiting structure 340 has a tendency to separate from the first limiting member 410, and a large elastic force needs to be provided by the elastic member 420. In this case, if the downward pressure is too large, the inclination angle of the spoiler 100 may fluctuate within a certain angle range, which is not conducive to adjusting the inclination angle of the spoiler 100 according to actual needs.

[0117] Another embodiment of the present invention provides a vehicle, including the above - mentioned spoiler device. This vehicle has the beneficial effects of this spoiler device, which will not be described in detail here.

[0118] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium.
