[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 9 A moving mechanism for a vehicle diffuser and a vehicle diffuser according to embodiments of the present invention are described.

[0034] like Figure 1-Figure 9 As shown, the motion mechanism for the vehicle diffuser includes a drive unit and a swing arm 7 .

[0035] The driving unit includes a driving cross bar 6 and a driving member 5, the driving member 5 is fixed on the driving cross bar 6, and the swing arm 7 is movably mounted on the driving cross bar 6 along the circumference of the driving cross bar 6. The driving cross bar 6 rotates to drive the driving member 5 and the swing arm 7 to stop the swing arm 7 so that the swing arm 7 swings from the first position to the second position, thereby causing the spoiler blades 2 of the vehicle diffuser to swing from the closed position to the open position.

[0036] In this way, the driving cross bar 6 rotates, and the driving member 5 rotates synchronously with the driving cross bar 6. At the same time, the swing arm 7 starts to swing around the circumference of the driving cross bar 6 from the first position. When the driving member 5 rotates to abut against the swing arm 7, the swing arm 7 cannot continue to swing due to the stopping force of the driving member 5. At this time, the swing arm 7 is in the second position, thereby realizing the swing arm 7 from the first position to the second position, so that the spoiler blade 2 can be swung from the closed position to the open position.

[0037] It can be understood that the driving cross bar 6 is a component that receives driving force, and can receive driving force from an external power source, such as a driving motor 4. After the driving motor 4 receives current, it outputs power to drive the driving cross bar 6 to rotate.

[0038] Therefore, according to the motion mechanism of the utility model, by driving the cross bar 6 to rotate to drive the driving member 5 to stop and cooperate with the swing arm 7, the swing arm 7 is swung from the first position to the second position, so that the spoiler blade 2 of the vehicle diffuser can be swung from the closed position to the open position. Compared with the fixed spoiler blades in the diffuser of the prior art, the utility model provides a motion mechanism for the vehicle diffuser. When the spoiler blades of the diffuser have different position requirements, the motion mechanism of the utility model can drive the spoiler blades to move to the required position to meet the needs of the vehicle using the diffuser under different working conditions. And the motion mechanism of the utility model drives the driving member to stop and cooperate with the swing arm to realize power transmission by driving the cross bar to rotate, which can make the spoiler blade 2 move smoothly during the entire movement process.

[0039] Furthermore, the driving member 5 has a driving member stop surface 501, and the swing arm 7 has a swing arm stop surface 701. The swing arm stop surface 701 and the driving member stop surface 501 can be detachably matched. The swing arm stop surface 701 and the driving member stop surface 501 are suitable for radial stop along the driving cross bar 6 to make the swing arm 7 swing from the first position to the second position.

[0040] See Figure 6 As shown, since the swing arm 7 is movably sleeved on the driving cross bar 6, when the driving cross bar 6 drives the driving member 5 to rotate until it abuts against the swing arm 7, the swing arm abutment surface 701 and the driving member abutment surface 501 abut against each other in the radial direction of the driving cross bar 6. It can be understood that the contact surface formed by the swing arm abutment surface 701 and the driving member abutment surface 501 abutting against each other is arranged around the outer peripheral surface in the radial direction of the driving cross bar 6, and further, the formed contact surface can be arranged tangentially to the outer peripheral surface, so that a reliable abutment force can be provided for the swing arm 7, and the spoiler blade 2 can be opened away from the base 1.

[0041] Optionally, the swing arm abutment surface 701 and the drive member abutment surface 501 are respectively formed as planes, such as Figure 6 shown.

[0042] In this way, the swing arm abutment surface 701 and the driving member abutment surface 501 are both planes, which increases the abutment area between the swing arm 7 and the driving member 5, thereby effectively driving the spoiler blade 2 to rotate from the closed position to the open position.

[0043] Further, refer to Figure 5 The swing arm 7 includes a first swing arm sleeve 702 and a second swing arm sleeve 703 which are arranged at intervals. The first swing arm sleeve 702 and the second swing arm sleeve 703 are movably mounted on the driving cross bar 6 along the circumference of the driving cross bar 6, and the driving member 5 is located between the first swing arm sleeve 702 and the second swing arm sleeve 703.

[0044] In this way, a matching space between the driving member 5 and the swing arm 7 is defined between the first swing arm sleeve 702 and the second swing arm sleeve 703, and the driving member 5 is arranged in the matching space. In the process that the driving member 5 pushes the swing arm 7 to swing from the above-mentioned first position to the above-mentioned second position, the first swing arm sleeve 702 and the second swing arm sleeve 703 both rotate circumferentially around the driving cross bar 6, so that the overall force of the swing arm 7 is balanced, which can further effectively ensure the smooth movement of the swing arm 7.

[0045] Furthermore, combined with Figure 5-Figure 7 As shown, the motion mechanism further includes: a limiter 9, which passes through the driving cross bar 6 and the driving member 5 to fix the driving member 5 on the driving cross bar 6. In this way, the driving member 5 can be fixed on the driving cross bar 6 through the limiter 9, so that the driving member 5 can rotate synchronously with the driving cross bar 6, so that when the driving member 5 stops against the swing arm, the swing arm 7 can be driven to swing.

[0046] Optionally, the stopper 9 is an elastic cylindrical pin, and the driving member 5 is fixed to the driving cross bar 6 by interference fit through the stopper 9. In this arrangement, by adopting the elastic cylindrical pin, since the elastic cylindrical pin has good elasticity and shear resistance, while ensuring that the driving member 5 is fixed to the driving cross bar 6, the connection reliability of the driving member 5 and the driving cross bar 6 can be effectively guaranteed, thereby effectively ensuring that the spoiler blade 2 swings smoothly from the closed position to the open position. Of course, the stopper 9 can also be other fixing structures, as long as the driving member 5 can be fixed to the driving cross bar 6.

[0047] Optionally, refer to Figure 5 and Figure 6 The driving member 5 is a cam. The cam has a simple structure and is convenient to design, and can satisfy the desired movement of the spoiler blade 2. Figure 6 In the example, the cam has an arc end and a tip. When the driving cross bar 6 drives the cam to rotate until the side of its tip abuts against the swing arm 7, the swing arm 7 can smoothly swing from the first position to the second position, thereby ensuring that the spoiler blade 2 opens smoothly.

[0048] In some embodiments of the present invention, Figure 6 , Figure 8 and Fig. 9 As shown, the swing arm 7 includes: a first swing arm 704 and a second swing arm 705, one end of the first swing arm 704 is movably mounted on the driving cross bar 6 along the circumference of the driving cross bar 6, one end of the second swing arm 705 is rotatably connected to the other end of the first swing arm 704, and when the swing arm 7 is in the second position, the first swing arm 704 and the second swing arm 705 are located on the same straight line.

[0049] Thus, when the motion mechanism moves to Fig. 9 In the state shown, the first swing arm 704, the second swing arm 705, the base 1 and the spoiler blade 2 form a triangle together. At this time, the first swing arm 704 and the second swing arm 705 move to the dead point of the motion mechanism, and the force direction of both is along the arm length direction of the swing arm 7. As a result, there is no influence of excess force that can disturb the rotation of the spoiler blade 2, and the spoiler blade 2 can be more stable when it is opened.

[0050] In some embodiments of the present invention, Figure 6 The first swing arm 704 has a through hole at one end adjacent to the second swing arm 705, and the second swing arm 705 has a through hole at one end adjacent to the first swing arm 704. The through hole of the first swing arm 704 is connected with the through hole of the second swing arm 705 for fasteners to be connected. The first swing arm 704 can realize flexible swinging, thereby driving the second swing arm 705 to flexibly swing.

[0051] like Figure 1-Figure 4As shown, the vehicle diffuser according to the embodiment of the second aspect of the utility model comprises: a base 1, at least one spoiler blade 2, a motion mechanism for the vehicle diffuser and a reset member 3. One end of the spoiler blade 2 is connected to the base 1, the driving unit of the motion mechanism is connected to the base 1, the swing arm 7 of the motion mechanism is connected to the other end of the spoiler blade 2, and both ends of the reset member 3 are stopped between the base 1 and the swing arm 7.

[0052] It can be understood that when the spoiler blade 2 needs to be opened, the driving cross bar 6 of the driving unit rotates to stop the driving member 5 and the swing arm 7, so that the swing arm 7 swings from the first position to the second position, thereby swinging the spoiler blade 2 from the closed position to the open position. When the spoiler blade 2 needs to be closed, the swing arm 7 is reset from the second position to the first position under the action of the reset member 3, thereby closing the spoiler blade 2.

[0053] Furthermore, combined with Figure 4-Figure 7 As shown, the reset member 3 is a reset torsion spring, which is sleeved on the driving crossbar 6 of the motion mechanism, and the two ends of the reset member 3 are respectively abutted against the swing arm 7 and the base 1. Thus, flexible swinging can be achieved during the swinging opening and closing process, making the swinging smoother, more stable, less impactful and less noisy, and the flexible swinging opening and closing can effectively prevent users from being pinched during use. But it is not limited to this.

[0054] It can be understood that when the spoiler blade 2 is closed, the reset torsion spring can provide a pre-tightening torque that makes its two ends stop against the swing arm 7 and the base 1 respectively. When the spoiler blade 2 needs to be opened, the drive motor 4 needs to overcome the pre-tightening torque of the reset torsion spring, that is, the drive motor 4 drives the drive cross bar 6 to swing, so that the drive member 5 stops against the swing arm 7, so that the end of the reset torsion spring that stops against the base 1 is away from the base 1, and the reset torsion spring undergoes elastic deformation under force. When the spoiler blade 2 needs to be closed, the drive motor 4 no longer applies a force to drive the drive cross bar 6 to rotate. At this time, the reset torsion spring provides a restoring force when the spoiler blade 2 is closed, and the spoiler blade 2 rotates to the closed position under the restoring force of the reset torsion spring. In this way, the number of coils of the reset torsion spring can be designed according to the size of the spoiler blade 2 to adjust the size of the restoring force of the reset torsion spring, which can ensure the automatic closing of the spoiler blade 2.

[0055] Furthermore, a stopper 8 is provided on the driving cross bar 6, and the reset member 3 is located between the stopper 8 and the swing arm 7 to limit the axial movement of the reset member 3 in the driving cross bar 6. In this way, the reset member 3 can be ensured to be axially stable in the driving cross bar 6, thereby ensuring that one end of the reset member 3 can effectively stop against the swing arm 7.

[0056] A vehicle according to an embodiment of the third aspect of the utility model includes a movement mechanism for a vehicle diffuser or a vehicle diffuser.

[0057] According to the vehicle of the embodiment of the utility model, the overall performance of the vehicle can be effectively improved by adopting the above-mentioned motion mechanism or vehicle diffuser. Specifically, it can realize free switching between low wind resistance and large downforce, and the opening and closing angle of the spoiler blade 2 is determined according to the heat dissipation requirements, temperature and vehicle speed of the whole vehicle, and can be freely retracted and extended to meet the requirements of different driving conditions. When the vehicle is driving at high speed, the vibration is small, the noise is small, and the operation is smooth, which can greatly improve the driving experience of the driver and passengers.
