DETAILED DESCRIPTION

[0041] The prior art uses a hinge structure, and the maximum height to which the hinge structure can lift the spoiler and the maximum angle to which the spoiler can be opened are limited by the lateral space provided by the vehicle body.

[0042] Specifically, the hinge structure is generally a multi-link motion mechanism, the length of each link depends on the lateral space left by the vehicle body, and the motion trajectory is limited after the links are riveted. When the lateral position of the closed state is converted to the vertical state, the angle and height are also limited by the motion trajectory. Therefore, the utility model discloses a vehicle spoiler device, which is directly adjusted in the vertical direction.

[0043] In the present application, the wind inlet side of the spoiler is the leading edge side of the spoiler, and the wind outlet side of the spoiler is the trailing edge side of the spoiler.

[0044] Example 1

[0045] Figure 1 and Figure 2 The front view and the left view of the automobile spoiler according to the first embodiment of the utility model are respectively shown when the spoiler is at the highest height and the opening angle is the largest. Figure 1 and Figure 2 It can be seen that the utility model provides a vehicle spoiler device, which comprises a spoiler plate 1, a base 2, a lifting mechanism group and a conversion mechanism.

[0046] The bottom bracket 2 is located below the spoiler 1 and is used to be fixedly connected to the automobile body. The lifting mechanism group includes a first lifting component 311 that can reciprocate linearly along the lifting direction, a first driving mechanism for driving the first lifting component 311 to move, a second lifting component 312 that can reciprocate linearly along the lifting direction, and a second driving mechanism for driving the second lifting component 312 to move. The first lifting component 311 is hinged to the first end of the spoiler 1 through the first shaft 11. The conversion mechanism connects the spoiler 1 and the second lifting component 312, and is used to convert the reciprocating linear movement of the second lifting component 312 relative to the first lifting component 311 along the lifting direction into the flipping movement of the spoiler 1 around the first shaft 11.

[0047] Specifically, the first lifting component 311 is hinged to the first end of the front edge side of the spoiler 1 through the first shaft 11. The conversion mechanism connects the rear edge side of the spoiler 1 and the second lifting component 312.

[0048] The automobile spoiler device provided in this embodiment realizes the lifting and lowering movement of the spoiler 1 and the flipping movement around the first axis 11 by using the lifting mechanism group and the conversion mechanism. Since the first lifting component 311 and the second lifting component 312 in the lifting mechanism group reciprocate in a straight line along the lifting direction, the problem that the hinge structure in the prior art cannot further increase the lifting height and opening angle of the spoiler due to the limitation of the lateral space of the vehicle body is solved.

[0049] In this embodiment, the first driving mechanism and the second driving mechanism have the same worm gear driving structure. Figure 3 The worm gear drive structure includes a screw 32, a worm wheel 33 and a worm 34. The worm 34 is meshed with the worm wheel 33, and the worm wheel 33 is coaxially fixedly connected with the bottom end of the screw 32. Figure 4 The screw rod 32 in the first driving mechanism is threadedly connected to the first lifting component 311 to form a thread pair, and the screw rod 32 in the second driving mechanism is threadedly connected to the second lifting component 312 to form a thread pair.

[0050] See now Figure 1 Two sets of lifting mechanism groups can be provided, and the two sets of lifting mechanism groups are symmetrically arranged at both ends of the base 2 along its length direction.

[0051] See now Figure 1 The base 2 can be arranged vertically, the first driving mechanism and the first lifting component 311 are arranged on one side of the base 2, and the second driving mechanism and the second lifting component 312 are arranged on the other side of the base 2.

[0052] See now Figure 1 The device includes a driving motor 4, and two driving motors 4 are provided and both have double-end outputs. For the two lifting mechanism groups, the worm 34 of the first driving mechanism is connected to one of the driving motors 4 through a transmission shaft, and the worm 34 of the second driving mechanism is connected to the other driving motor 4 through a transmission shaft.

[0053] See now Figure 4 The first lifting component 311 is sleeved on the outer side of the screw rod 32 of the first driving mechanism, and the second lifting component 312 is sleeved on the outer side of the screw rod 32 of the second driving mechanism.

[0054] The lifting mechanism group includes two guide cylinders 351, and both guide cylinders 351 are fixedly connected to the base 2. The two guide cylinders 351 are respectively sleeved on the outer side of the first lifting component 311 and the outer side of the second lifting component 312, and are respectively used to guide the movement of the first lifting component 311 and the second lifting component 312.

[0055] Specifically, see now Figure 4 The first lifting component 311 includes an inner cavity 3111 at the top and a nut structure 3112 at the bottom. The nut structure 3112 is used to cooperate with the screw rod 32 of the first driving mechanism. The screw rod 32 of the first driving mechanism is installed with a first limiting component 36 at the top and a second limiting component 37 at the bottom. When the screw rod 32 of the first driving mechanism rotates, the nut structure 3112 of the first lifting component 311 moves along the screw rod 32 between the first limiting component 36 and the second limiting component 37 at the bottom, and the top of the screw rod 32 of the first driving mechanism moves in the inner cavity 3111. When the first limiting component 36 contacts the nut structure 3112, the first lifting component 311 is at the top dead center position. When the second limiting component 37 contacts the nut structure 3112, the first lifting component 311 is at the bottom dead center position.

[0056] See now Figure 4 The first limiting component 36 may be a limiting block or a thrust washer. The second limiting component 37 may be a housing portion of the worm gear drive mechanism.

[0057] See now Figure 2 In this embodiment, the conversion mechanism includes a second shaft 51 and a connecting rod 52, the first end of the connecting rod 52 is hinged to the second lifting component 312 through the second shaft 51, and the second end of the connecting rod 52 is hinged to the second end of the spoiler 1 through the third shaft 53, so as to realize the conversion mechanism connecting the spoiler 1 and the second lifting component 312.

[0058] In this embodiment, the second axis 51 and the third axis 53 are parallel to the first axis 11. When the second lifting component 312 moves back and forth along the lifting direction relative to the first lifting component 311, the second lifting component 312 drives the spoiler 1 to flip around the first axis 11 through the connecting rod 52.

[0059] See now Figure 2 The device comprises a mounting bracket 6, which is fixedly connected to a side of the spoiler 1 close to the base 2. The first shaft 11 and the third shaft 53 are directly mounted on the mounting bracket 6.

[0060] Below, refer to Figures 1 to 4 , the method of using the automobile spoiler shown in this embodiment is explained.

[0061] When the spoiler 1 needs to be raised, the two driving motors 4 work simultaneously, driving all the worms 34 to rotate through the transmission shaft. The rotation of the worm 34 drives the worm wheel 33 and the screw 32 to rotate synchronously, thereby driving the first lifting component 311 and the second lifting component 312 to rise synchronously along the lifting direction, thereby lifting the mounting bracket 6 and the spoiler 1.

[0062] When the spoiler 1 needs to be lowered, it is only necessary to rotate the output shaft of the driving motor in the reverse direction.

[0063] When the spoiler angle needs to be adjusted, the drive motor 4 connected to the worm 34 in the second drive mechanism forms a speed difference with another drive motor, so that a speed difference is formed between the second lifting component 312 and the first lifting component 311, so that the spoiler is at a certain angle.

[0064] Example 2

[0065] Figure 5 The front view of the automobile spoiler device according to the second embodiment of the utility model is shown when the spoiler is at the highest height and the opening angle is the largest. Figure 6 The left side view of the automobile spoiler according to the second embodiment of the utility model is shown when the spoiler is at the lowest height and not opened.

[0066] See now Figure 5 and Figure 6 In this embodiment, the first lifting component 311 and the second lifting component 312 adopt the same lifting component structure, but different from the embodiment 1, the lifting component structure includes a support portion 3113 and a connection portion 3114 fixedly connected to the support portion 3113, and the support portion 3113 of the first lifting component 311 is hinged to the first end of the spoiler 1 through the first shaft 11, so that the first lifting component 311 is hinged to the first end of the spoiler 1 through the first shaft 11. The conversion mechanism connects the support portion 3113 of the spoiler 1 and the second lifting component 312, so that the conversion mechanism connects the spoiler 1 and the second lifting component 312.

[0067] The lifting mechanism group includes a guide block 352, two guide blocks 352 are provided and both are fixedly connected to the base 2, and the two guide blocks 352 are respectively slidably connected to the connecting portion 3114 of the first lifting component 311 and the connecting portion 3114 of the second lifting component 312. The connecting portion 3114 of the first lifting component 311 is provided with a nut structure 3112 for cooperating with the screw rod 32 of the first driving mechanism, and the connecting portion 3114 of the second lifting component 312 is provided with a nut structure 3112 for cooperating with the screw rod 32 of the second driving mechanism.

[0068] In this embodiment, the guide block 352, the screw rod 32 and the support portion 3113 of the first lifting member 311 are separated from each other, so that the first and second driving mechanisms can be inverted. Figure 5 .

[0069] See now Figure 6 Different from the conversion mechanism in the first embodiment, the conversion mechanism in the present embodiment includes a slide groove 54, and the top end of the second lifting component 312 is slidably connected to the slide groove 54. When the second lifting component 312 moves back and forth linearly, the top end of the second lifting component 312 slides in the slide groove 54, driving the spoiler 1 to flip around the first axis 11. The slide groove 54 is directly provided on the mounting bracket 6.

[0070] Example 3

[0071] Different from Embodiment 1 and Embodiment 2, this device does not include a mounting bracket 6, which is not shown in the figure.

[0072] When this embodiment adopts the conversion mechanism in Embodiment 1, the first shaft 11 and the third shaft 53 are directly mounted on the spoiler 1 .

[0073] When this embodiment adopts the conversion mechanism in Embodiment 2, the slide groove 54 is provided on the spoiler 1 .
