[0042] Example 1

[0043] See also Figures 1 to 4 This embodiment provides a vehicle spoiler device, which includes a base 17, a housing 1, a spoiler 2, a sliding member 4 and a conversion mechanism. Figure 1 As shown, the bottom bracket 17 is fixedly connected to the automobile body. The housing 1 is fixedly connected to the top surface of the bottom bracket 17. The first end of the spoiler 2 is pivotally supported on the housing 1 around the first axis 3. The sliding member 4 is arranged in the housing 1 so as to be reciprocatingly movable. The conversion mechanism connects the second end of the spoiler 2 and the sliding member 4, and is used to convert the reciprocating linear movement of the sliding member 4 relative to the housing 1 into the flipping movement of the spoiler 2 around the first axis 3.

[0044] See now Figure 2 and Figure 3The device comprises a rotating member 8, which forms a thread pair with the sliding member 4. The rotating member 8 is fixedly supported inside the housing 1 and has a rotation axis. The rotating member 8 is configured to be able to rotate around the rotation axis to drive the sliding member 4 to move back and forth linearly.

[0045] See now Figure 3 The device includes a driving unit 10, and the driving unit 10 is configured to provide rotational power for the rotating member 8. Specifically, the driving unit 10 can be a motor.

[0046] In this embodiment, if Figure 5 The conversion mechanism includes a second shaft 6 and a connecting rod 5, the first end of the connecting rod 5 is hinged to the sliding member 4 through the second shaft 6, and the second end of the connecting rod 5 is hinged to the second end of the spoiler 2 through the third shaft 417, so as to realize the conversion mechanism connecting the second end of the spoiler 2 and the sliding member 4.

[0047] The second axis 6 and the third axis 7 are parallel to the first axis 3. When the sliding member 4 moves back and forth linearly, the sliding member 4 drives the spoiler 2 to flip around the first axis 3 through the connecting rod 5.

[0048] Specifically, see now Figure 4 and Figure 5 The device includes a mounting bracket 14, which is fixedly connected to the side of the spoiler 2 close to the housing 1. The first shaft 3 and the second shaft 6 are both rotatably mounted on the mounting bracket 14. When the sliding member 4 moves back and forth linearly, the sliding member 4 drives the mounting bracket 14 and the spoiler 2 to turn around the first shaft 3 synchronously through the connecting rod 5.

[0049] In this embodiment, the first axis 3, the second axis 6 and the third axis 7 are all parallel to the transverse axis of the vehicle.

[0050] See now Figure 3 The rotation axis of the rotating member 8 and the reciprocating linear movement direction of the sliding member 4 can be in the vertical direction or in other directions, depending on their installation angles with the vehicle body.

[0051] See now Figure 3 The rotating member 8 is sleeved on the outer side of the sliding member 4 and is rotatably connected to the housing 1 through a bearing.

The cavity wall of the meshing cavity 81 is provided with an internal thread, and the sliding member 4 includes a stage 41, a meshing section 42 and a guide section 43 arranged in sequence, and the guide section 43 is slidably matched with the sliding cavity 82, and the meshing section 42 is meshed with the internal thread of the meshing cavity 81. When the sliding member 4 slides to the end of the stroke in the contraction direction, the stage 41 of the sliding member 4 abuts against the rotating member 8. When the sliding member 4 slides to the end of the stroke in the extension direction, the guide section 43 abuts against the cavity wall of the sliding cavity 82 close to the meshing cavity 81.

[0052] It should be understood that the sliding member 4 and the rotating member 8 may also be arranged such that the sliding member 4 is sleeved on the outer side of the rotating member 8, which is not shown in the figure.

[0053] In this embodiment, in order to be suitable for the vehicle body installation space with limited lateral space but not limited vertical space, the output shaft of the motor is connected to the rotating member 8 through a spline shaft 15, or indirectly connected through a square shaft, for directly driving the rotating member 8.

[0057] In this embodiment, a gear transmission mechanism is provided to achieve an offset of the drive unit 10 relative to the rotating member 8, and the given space can be flexibly utilized to avoid interference of related parts.

[0058] Optionally, when the output gear 12 is integrated with the rotating member 8, the output gear 12 is sleeved outside a portion of the rotating member 8 that forms a thread pair with the sliding member 4, which is not shown in the figure.

[0062] In one embodiment of the gear transmission mechanism, the input gear 11 is directly meshed with the output gear 12, which is not shown in the figure.

[0063] In another embodiment of the gear transmission mechanism, now referring to Figure 8 The gear transmission mechanism also includes an intermediate gear 13, and the input gear 11, the intermediate gear 13, and the output gear 12 are meshed with each other.

[0064] It should be understood that the number of the intermediate gears 13 is not limited to one, but may be multiple, and can be increased or decreased according to actual needs.

[0065] Example 3

[0069] Example 5

[0070] Different from the first embodiment, the device of the present embodiment does not include an independent mounting bracket 14, and the conversion mechanism includes a slide groove 16, which is directly arranged on the spoiler 2. When the sliding member 4 moves back and forth linearly, the top end of the sliding member 4 slides in the slide groove 16, directly driving the spoiler 2 to flip around the first axis 3.
