Detailed Description

Fig. 1 shows a schematic partial view of a vehicle side according to an embodiment of the invention. As shown in fig. 1, the vehicle includes a front side window 1, a rear side window 2, a front side window B-pillar sash 3, a rear side window B-pillar sash 4, and a front door corner trim 5. Fig. 2 shows a schematic structural view of a door trim assembly for reducing rear side window wind vibration of a vehicle according to an embodiment of the present invention, in which a door trim 61 is shown rotated by a certain angle. As shown in fig. 2, the door trim assembly 6 includes a door trim 61 and a drive motor (not shown). The door outer garnish 61 is rotatably provided at a B pillar or a front door corner garnish 5 of the vehicle. It is to be understood that the arrangement in which the door trim 61 is provided at the B-pillar means that the door trim 61 is provided at the front side window B-pillar sash 3 or the rear side window B-pillar sash 4. The driving motor has an output shaft connected to one side of the door trim 61, and is configured to determine a rotation angle according to a vehicle speed and/or an in-vehicle noise value, thereby driving the door trim 61 to rotate, so that the vehicle does not have a wind vibration phenomenon at any vehicle speed of 30-110 km/h.

According to the utility model discloses a scheme, through the B post at the vehicle or the 5 rotatable door exterior trimming boards 61 of preceding door corner trim board department installation, and judge the turned angle of door exterior trimming boards 61 according to the speed of a vehicle and/or noise value in the car through driving motor to drive door exterior trimming boards 61 and rotate certain angle, can reduce wind vibration in the car from this, solve 2 wind vibrations of rear side window among the prior art comparatively serious, thereby damage the sense of hearing and influence the technical problem of riding comfort. And the scheme can ensure that the vehicle has no wind vibration phenomenon at any vehicle speed of 30-110 km/h.

In the embodiment shown in fig. 1, the door outer panel 61 is provided at the rear side window B-pillar sash 4. As shown in fig. 1, in the initial state, i.e., the side window is not opened, the door outer panel 61 is flush with the rear side window B-pillar sash 4. It is understood that, when the door outer 61 is disposed on the front side window B-pillar sash 3, it is flush with the front side window B-pillar sash 3 in the initial state. When the door outer panel 61 is mounted on the front door corner trim 5, it is flush with the front door corner trim 5 in its initial state. As shown in fig. 2, the door trim 61 is rotated toward the outside of the vehicle when it starts to rotate. Fig. 3 shows a schematic back structural view of a door outer trim panel according to an embodiment of the present invention. In the embodiment shown in fig. 1 to 3, the door trim 61 is configured to continuously extend from the top of the side window frame to the bottom of the side window frame. That is, the door outer panel 61 is a continuous plate.

In one embodiment, the rotation angle of the door trim 61 may be, for example, 30 °, 60 °, or 90 °, or any other angle in the range of 0 to 90 °. The turning angle is determined according to the vehicle speed and/or the wind noise value in the vehicle.

In one embodiment, when the side window of the vehicle is in an open state and the vehicle speed is greater than a first preset vehicle speed, the driving motor drives the door trim 61 to rotate by a first preset angle, so as to start to play a role of turbulence, destroy a necessary condition for generating wind vibration, and prevent the wind vibration. When the vehicle speed continues to increase and increases to a second preset speed, the driving motor drives the vehicle door outer decoration plate 61 to rotate by a second preset angle on the basis of the first preset angle, wherein the first preset speed is smaller than the second preset speed. Therefore, the rotation angle of the door outer plaque 61 can be changed according to the vehicle speed value, thereby ensuring that the vehicle has no wind vibration phenomenon at any vehicle speed of 30-110 km/h.

In another embodiment, when the noise value inside the vehicle is greater than the first preset noise value, the driving motor drives the door trim 61 to rotate by a first preset angle, so as to start playing a role of turbulence, destroy the necessary condition of generating wind vibration, and prevent wind vibration. When the noise value in the vehicle continues to increase and increases to a second preset noise value, the driving motor drives the vehicle door outer decoration plate 61 to rotate by a second preset angle on the basis of the first preset angle, wherein the first preset speed is less than the second preset speed. Therefore, the rotation angle of the door outer plaque 61 can be changed according to the noise value, thereby ensuring that the vehicle has no wind vibration phenomenon at any vehicle speed of 30-110 km/h.

Fig. 4 shows a schematic block diagram of a control system for reducing rear side window wind vibration of a vehicle according to an embodiment of the present invention. The control system comprises the vehicle door outer decoration plate assembly 6, a vehicle speed sensor 7, a wind noise detection unit 8 and a controller 9. The vehicle speed sensor 7 is used to detect the vehicle speed of the vehicle during running. The wind noise detection unit 8 is used to detect a noise value inside the vehicle during running of the vehicle. The controller 9 is connected to the vehicle speed sensor 7, the wind noise detection unit 8, and the driving motor of the door trim assembly 6 to determine a rotation angle according to the vehicle speed and/or the vehicle interior noise value, so that the driving motor drives the door trim 61 of the door trim assembly 6 to rotate.

When a side window of the vehicle is in an open state and the vehicle speed is greater than a first preset vehicle speed, and/or when a noise value in the vehicle is greater than a first preset noise value, the driving motor outputs driving force, so that the vehicle door outer decoration plate 61 is driven to rotate by a first preset angle. The door trim 61 is configured to rotate by a second preset angle on the basis of the first preset angle when a side window of the vehicle is in an open state and the vehicle speed is greater than a second preset vehicle speed and/or when the noise value in the vehicle is greater than the second preset noise value. And the second preset vehicle speed is greater than the first preset vehicle speed, and the second preset noise value is greater than the first preset noise value. Other features of the control system for reducing wind vibration of the rear side window 2 of the vehicle correspond to those of the door trim assembly 6, and are not described in detail herein.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
