Description

Vehicle window decorative board assembly and vehicle rearview mirror assembly

[ technical field ] A method for producing a semiconductor device

The present application relates to a vehicle trim panel assembly and a vehicle rearview mirror assembly.

[ background of the invention ]

Noise of the vehicle is a factor that affects customer satisfaction. Manufacturers have also improved NVH performance by a number of different attempts to enhance the user experience.

In the driving process, when a vehicle window is closed, the streamline of the vehicle and the relatively smooth vehicle side design enable the wind resistance of the vehicle to be small, the fuel economy to be good, and the wind noise to be small. However, when the window is opened while driving, a large Wind noise is generated, which is called as a driving Wind noise "Wind Throb" and is generated due to a booming noise generated when the window is opened and air flows through the window while driving.

US patent publication US20100109377a1 discloses a foldable spoiler for a rear door window of a vehicle connecting a B-pillar or window frame. The spoiler assembly includes a spoiler that is proximate to the glass panel of the rear door window when the window is closed. When the window is opened, the spoiler is deployed from the inside to the outside of the vehicle due to the biasing force of the spring, and when the window is closed, the spoiler is moved to a closed position inside the vehicle by physical contact with the window that is being raised closed.

US7641275B2 discloses a B-pillar spoiler for a vehicle window. Specifically, a plate-shaped spoiler is provided on the B-pillar of the vehicle, and is movable between an open position and a closed position, and the spoiler may be connected to the controller, and the controller opens or closes the spoiler by detecting whether the rear window is opened or not through user activation or through a sensor.

The inventor of the present application has recognized that although the provision of the spoiler on the B-pillar can solve the problem of wind noise when the rear window is opened to some extent, it has an adverse effect on the appearance, and does not solve the problem of wind noise when the front window is opened. The inventors of the present application have thus recognized a need for a spoiler that alleviates the wind noise problem when the front window is open and does not affect the appearance of the vehicle.

[ detailed description ] embodiments

With reference to the figures, the same or similar reference numerals are used to designate the same or similar components. In the following description, various operating parameters and components are described in various embodiments. These specific parameters and components are included herein by way of example only and are not meant to be limiting.

As required, detailed embodiments of the present application are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the application and may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present application.

As mentioned in the background, the noise performance of a vehicle impacts the user experience. The user expects that neither opening nor closing the window during driving will experience a loud noise. Through the spoiler that sets up to be located door rear window side, can solve the wind noise problem behind the windowing to a certain extent, but when closing the window, acoustic performance, aerodynamic performance and fuel economy when such spoiler design can adversely influence the window of closing. A compromise in the prior art is to provide a retractable spoiler near the B-pillar, which is mechanically or electrically activated to open and close the spoiler. However, the addition of the spoiler at the B-pillar affects the appearance whether it is located inside or outside the vehicle when stowed, increases the complexity of the system, and does not solve the noise problem when the front window is opened. The inventor of the application realizes that the function of the spoiler can be integrated on the window corner decorative plate or integrated with the rearview mirror in other cases, the adjustment of the wind noise of the window opening of the vehicle is realized through the design of the variable window corner decorative plate or the rearview mirror shell, and the dynamic performance when the window is closed is ensured. Thus, in one or more of the following embodiments, the inventors of the present application provide a spoiler assembly that is located adjacent a front window.

FIG. 1 illustrates a perspective view of a vehicle 100 in one or more embodiments of the present application. As shown, the vehicle 100 has a passenger side/driver side window 102 located relatively at the front of the vehicle and a passenger compartment side window 104 located relatively at the rear of the vehicle 100. As an example, arrow 103 in fig. 1 shows the direction of the airflow when the side front window 102 is opened. Particularly, when the vehicle 100 is driven above a certain speed, air may rapidly enter the vehicle as indicated by an arrow 103, and air flow directly entering the vehicle may generate a loud noise. One way in which noise may be mitigated is to open the rear row of further windows 104, which may not be desirable to other passengers. The inventors of the present application thus provide an adjustable spoiler assembly integrated at a position of a front window of a vehicle. The spoiler can be respectively in the deployed and stowed positions according to the opening and closing of the front window, and thus does not affect the appearance of the vehicle as a whole.

FIG. 2 illustrates a spoiler assembly 200 according to a first embodiment of the present application. As shown, spoiler assembly 200 includes a base plate 210 positioned forward of a front window 102 of a vehicle and a spoiler 230 rotatably coupled to base plate 210. In the illustrated example, the substrate 210 is a trim panel for a front window. The trim panel 210 is relatively independent of the rear view mirror 220, i.e., the rear view mirror 220 is not mounted on the trim panel 210. The front of the vehicle is denoted by F. The front portion of the front window 102 refers to a portion that extends relatively rearward from a position B of the front window 102 that is closest to the vehicle head, for example, the front length of the front window 102 is represented by the illustrated distance L. In one embodiment, the front length L may refer to a position that does not exceed 1/2 lengths of the front window, for example. In another embodiment, the front length L of the front window 102 may be a position that does not exceed 1/3 length of the front window. In yet another embodiment, the front length of the front window 102 refers to a length that does not exceed a portion of the position C to which the rear view mirror 220 corresponds. In this embodiment, a base or trim panel 210 is connected to a front window frame 212 and forms part of the sidelite closure member 102. The trim panel 210 shown in fig. 2 is generally triangular with a bottom edge 214 that is generally horizontal and flush with the bottom of the window frame, and in some examples, the trim panel 210 may also be referred to as a gusset (sand panel). The spoiler 230 extends generally along the height direction H of the vehicle or in a direction perpendicular to the base 214 toward the opposing hypotenuse 216 of the triangle. In the illustrated embodiment, the two ends 232 of spoiler 230 are adjacent to bottom edge 214 and hypotenuse 216, respectively. Spoiler 230 is shown in a stowed position in figure 2. In this stowed position, the first surface 231 of the spoiler 230 is substantially flush with the outer surface 211 of the trim panel 210. In one or more of the embodiments described above, the trim panel 210 may be provided with an opening for receiving the spoiler 230.

Although in the above-described embodiment, the trim panel 210 is shown as a unitary triangle and the spoiler 230 extends generally perpendicular to the base 214, it will be appreciated that the trim panel 210 and the spoiler 230 may have different designs. For example, the trim panel 210 may be an integral or separate panel. Turbulator 230 may have a variety of shapes and orientations. In one embodiment, spoiler 230 may be a plate designed to fit snugly against trim panel 210 and may have a rectangular, triangular, or any suitable decorative shape. For example, may have an associated shape with a vehicle logo, OEM logo or personalization. In the above example, the trim panel 210 may not be provided with an opening, but may have a continuous shape and provide a recess to accommodate the spoiler 230. The spoiler 230 may be designed at any suitable angle relative to the trim panel 210 so long as the spoiler 230 provides a windward surface and achieves the desired wind noise reduction effect when in the open position. In the above embodiment, when the spoiler 230 is cylindrical, it is also possible to design the windward side as large as possible. In other embodiments, a combination of factors, such as the streamline design of the vehicle body itself, wind noise conditions, strength of the spoiler when deployed, and the like, may be considered, and the appropriate size may be selected through experimentation or simulation.

FIG. 3 illustrates a spoiler assembly 300 in a second embodiment of the present application. As shown, spoiler assembly 300 is positioned forward of a front window of a vehicle and includes a base plate 310 and a spoiler 330 movably coupled to base plate 310. In the illustrated embodiment, the base plate 310 is a trim panel located in front of the front window 102 of the vehicle, and the rear view mirror 320 is integrated on the trim panel 310. The front of the vehicle is denoted by F. The decorative plate 310 and the spoiler 330 may be disposed in a similar manner as in the first embodiment, and for the sake of brevity, will not be described again. The difference from the first embodiment is that the rear view mirror 320 is integrally formed with the decorative plate 310 and the spoiler 330 in this embodiment. The size, shape, and placement of spoiler 330 at the location of trim panel 310 may further take into account the effect of rear view mirror 320 on wind noise.

FIG. 4 illustrates a spoiler assembly 400 in a third embodiment of the present application. As shown, the rear spoiler assembly 400 includes a base plate 410 and a spoiler 430 movably coupled to the base plate 410. In the illustrated embodiment, the substrate 410 is part of a housing 422 of the rearview mirror 420. The rear view mirror 420 is integral with a front window trim panel 412, the base panel 410 being adjacent the front of the front window 102 of the vehicle. The term adjacent may refer to a position close to the front of the vehicle window, for example as explained for the front window in the above embodiments. The spoiler 430 may be coupled to the base plate 410 and operate in the same manner as the base plate 210/310 and the

spoilers

230, 330 of the first and second embodiments. The difference from the first and second embodiments is that in this embodiment, the base plate 410 is a part of the housing of the rear view mirror 420, and the base plate 410 is relatively independent from the window trim 412. It is understood that the spoiler 430 may be integrated into the housing 422 of the rearview mirror 420 at any suitable location, such as in the illustrated embodiment, the spoiler 430 is disposed on a side of the housing 422 of the rearview mirror 420 adjacent the front window 102. The spoiler 430 is retractable into the housing 422 in the stowed position, with a surface of the spoiler 430 flush with a surface of the housing 422, and extends to a position proximate the front side window in the deployed position to spoiler. In another embodiment, the spoiler 430 is positioned on the housing 422 in a stowed position relatively away from the front window and in a deployed position relatively closer to the front window in order to provide a better spoiler effect.

Fig. 5A-5D illustrate a spoiler assembly 500 according to a fourth embodiment, wherein fig. 5A-5B illustrate perspective and cross-sectional views, respectively, of a spoiler 530 in a stowed position, and fig. 5C-5D illustrate perspective and cross-sectional views, respectively, of the spoiler 530 in an open position. It is understood that the specific configuration of the spoiler assembly 500 shown in fig. 5A-5D may be adapted for use with any of the embodiments described above.

The spoiler assembly 500 shown in fig. 5A-5D includes a base plate 510 and a spoiler 530 movably coupled to the base plate 510, the spoiler 530 being disposed in an opening 512 extending through the trim plate 510. The spoiler 530 may be fixedly coupled to the hinge 533, and the hinge 533 may be movably coupled to a rear portion (i.e., a side facing the interior of the vehicle) of the base plate 510, or a window frame, among other optional coupling positions. The base plate 510 is shown as being generally triangular, with the base 514 generally horizontal and flush with the bottom of the window frame (with reference to fig. 2), and the spoiler 530 generally extends in the height direction H of the vehicle, or in a direction perpendicular to the base 514, toward the opposite side 516 of the triangle. Referring to the cross-sectional view along line A-A of FIG. 5B, it can be seen that in this stowed position, the first surface 531 of the spoiler 530 and the outer surface 511 of the trim panel 510 are substantially flush. As mentioned above, the spoiler 530 may be disposed proximate to the vertical edge 515, may generally extend in the height direction H, and in other embodiments, the spoiler 530 may not be parallel to the height direction H as long as the spoiler 530 is deployed to provide a protruding windward side of the spoiler.

Referring to fig. 5C-5D, spoiler 530 is in an open position. In the open position, the first surface 531 of the spoiler 530 protrudes from the outer surface 511 of the base plate 510, depending on the installation direction, with the first surface 531 or the adjacent surface 532 forming the windward side. In the depicted embodiment spoiler 330 has a substantially triangular or fan-shaped cross-section, that is to say a cross-section in a direction perpendicular to vehicle height H. In one embodiment the cross-section of the triangle is an isosceles triangle. In the stowed position a first surface 531 where the isosceles triangle first side 520 is located is adjacent to or flush with the outer surface 511 of the base plate 510, in the deployed position the first surface 531 protrudes from the outer surface 511 of the trim panel 530 to form a windward surface, and a second surface 532 where a second side 522 substantially equal and opposite to the first side is located is adjacent to or flush with the outer surface 511 of the base plate 510. A cross section of the spoiler 530 along a direction L substantially perpendicular to the height direction H is a sector of an equal radius.

Referring to the fifth embodiment of fig. 6, the spoiler assembly 600 includes a base plate 610 and a spoiler 630 movably coupled to the base plate 610, wherein the spoiler 630 is movably coupled to the base plate 610 or other suitable position in the window area by a rotating shaft 634. The spoiler 630 is generally triangular cylindrical or cylindrical sector shaped in cross-section and similarly includes a first surface 631 that is generally flush with the outer surface 611 of the base 610 in the stowed position and a second surface 632 that is proximate to the outer surface 611 of the trim panel in the open position. In the embodiment shown in FIG. 6, spoiler 630 has a first flange 633 extending from an edge of first surface 631 in height direction H or along a column and a second flange 635 extending from an edge of second surface 632, where first flange 633 may overlap outer surface 611 of the base plate to form a smooth exterior in the stowed position. In the deployed position, the second flange 635 may overlap the interior surface of the trim panel to facilitate retention and prevent the spoiler 630 from becoming dislodged from the trim panel exterior surface 611 in its entirety, or in other words, from the opening in the base outer surface 611. The first flange 633 and the second flange 635 may be made of an elastic material, such as rubber, which may increase sealing. It is understood that the first flange 633 and the second flange 635 may not necessarily extend entirely along the longitudinal direction of the spoiler 630, and the limiting function may be achieved by one or more protrusions. In other embodiments, a protrusion or stop feature may be provided on only one side, e.g., 631 side or 632 side.

Referring to FIG. 7, in another embodiment, spoiler assembly 700 comprises a base plate (not shown) and spoiler 730 movably coupled to the base plate, a shaft 732 coupled to spoiler 730, a drive system 740 coupled to shaft 732, and a controller 750. The driving mechanism of this embodiment can be used in one or more embodiments herein and in other locations, for example, the shaft 732 can correspond to the

shafts

533, 634 in the above embodiments. Controller 750 is configured to instruct drive system 740 to drive spoiler 730 between the stowed and deployed positions. In the illustrated embodiment, wherein the drive system 740 includes a motor 741, other suitable drive arrangements are also contemplated. The motor 741 is connected to a vehicle drive battery or starter battery or other energy source 760 and is further connected to the controller 750 as mentioned above. In one or more embodiments, the controller 750 may be separately provided, configured to communicate with a plurality of systems and sensors 770 of the vehicle, and the controller 750 may also be integrated with or may communicate with a Vehicle System Controller (VSC) or the like and may also communicate with a plurality of vehicle sensors. The control system for a vehicle may include any number of controllers and may be integrated into a single controller or have multiple modules. Some or all of the controllers may be connected through a Controller Area Network (CAN) or other system. The controller and vehicle control system may include a microprocessor or Central Processing Unit (CPU) in communication with various types of computer readable storage devices or media. The computer readable storage device or medium may include volatile and non-volatile storage such as Read Only Memory (ROM), Random Access Memory (RAM), and Keep Alive Memory (KAM). The KAM is a persistent or non-volatile memory that can be used to store a plurality of operating variables when the CPU is powered down. The computer-readable storage device or medium may be implemented using any number of known storage devices such as programmable read-only memory (PROM), electrically programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), flash memory, or any other electronic, magnetic, optical, or combination memory capable of storing data.

With continued reference to fig. 7, the driving system includes a motor 741, a first toothed member 742 connected to the motor 741, a second toothed member 734 sleeved or fixedly connected to the shaft 732, the first toothed member 732 engaging with the second toothed member 734, such that the motor 741 can rotate the first toothed member 742, the first toothed member 742 further rotates the second toothed member 734 and the shaft 732, the shaft 732 can be movably connected to the substrate (e.g., the

substrate

210, 310, 410, 510, 610), and the spoiler 730 can be driven by the motor 741 to move relative to the substrate. It will be appreciated that the first and second toothed members may be any suitable member including, but not limited to, gears, sectors, racks, worms, etc. in a mating manner.

Referring to FIG. 8A, FIG. 8B, a spoiler assembly 800 in accordance with yet another embodiment of the present invention is shown. The spoiler assembly 800 includes a base plate 810, a spoiler 830 movably coupled to the base plate 810, and a shaft (not shown) coupled to the spoiler 830. Figures 8A and 8B show spoiler 830 in stowed and open positions, respectively. In this embodiment, the base plate 810 is a trim panel in front of the front window frame 812. In the illustrated embodiment, the trim panel 810 forms a triangular shaped recess 816. The spoiler 830 may have a shape similar to the recess 816 and may be received within the recess 816. Spoiler 830 has a bottom edge 834, a beveled edge 836, and a perpendicular angled edge 835. The spoiler 830 can pivot about a right-angled edge 835 perpendicular to the bottom edge 834 to move between a stowed position and a deployed position. Similarly, spoiler 830 may be connected to trim panel 810 by a rotational shaft (not shown) that is substantially parallel to the height direction H of the vehicle. Spoiler 830 may be rotated open toward the outside of the vehicle along sloped edge 836 to a deployed position. It is to be appreciated that the bottom edge 834 and the edge 835 need not be perfectly perpendicular and can have any suitable angle, and that as the spoiler 830 moves between the stowed and open positions, the spoiler 830 can define a windward surface 837 (i.e., the inner surface of the spoiler 830 when in the stowed position) that faces the front F of the vehicle, thereby creating a spoiler effect. In another embodiment, the axis of rotation may be parallel to the beveled edge 836. Spoiler 830 may be opened to a deployed position about an axis of rotation of generally parallel beveled edge 836 in a direction away from the vehicle body. The windward side of spoiler 830 is the outer surface when in the stowed position).

In other embodiments, spoiler 830 may not completely cover all of recess 816 of trim panel 810, but may cover only a portion of trim panel 810, such as a portion extending forward F of the vehicle proximate edge 835, or an appropriate portion beginning at a middle location of trim panel 810. Thus, in one or more of the examples described above, the base 810 may have a continuous surface without requiring openings therethrough, and the base 810 may have a continuous surface including suitable recesses to accommodate spoilers. In yet another embodiment, the recess 816 may be an opening, and the spoiler 830 may cover the opening entirely or partially, and another portion may be made of the same material or a different material (e.g., a hard plastic) and cover the opening together with the spoiler 830. While spoiler 830 may have any suitable ornamental shape, such as the shape of the vehicle personalization features described above, such as wings, emblems, other features associated with the vehicle, and the like. The windward surface of the spoiler 830 or the wind guide surface at this or other positions may be a plane or a curved surface with a certain curvature, and the shape can be adapted according to the design requirement.

With continued reference to fig. 2-8B, in yet another embodiment, the spoiler assembly further includes a skin (not shown) at least partially covering the spoiler, which may have some elasticity. In some embodiments (e.g., the first embodiment, the base plate 210 includes a through opening that receives the spoiler 230, such that the spoiler skin covers at least the seam between the spoiler 230 and the trim panel 210. in one example, the different positions of stowing and protruding may be achieved by the skin being fully covered, but within the skin by a movable mechanism, such as the motor gear drive described above.

It should be appreciated that the spoiler assembly of fig. 2-6, 8A-8B may include the shaft, drive system, controller and other elements shown in fig. 7. The spoiler is rotatable between stowed and deployed positions as commanded by the controller. Fig. 9 shows a schematic flow diagram of the controller controlling the spoiler movement, which may be used for the spoiler opening or closing and position adjustment in the above-described embodiments. Referring to fig. 9, in conjunction with fig. 1-8B, the method 900 begins at 902 and then detects whether a trigger condition for spoiler movement is satisfied at step 904. In one embodiment, the trigger condition for spoiler movement comprises a window opening command, and the controller 750 may be configured to trigger the motor 741 to change the spoiler from the stowed position to the deployed position upon receipt of the window opening command. In another embodiment, the trigger condition for spoiler movement comprises a window opening to a first opening, and the controller 750 is configured to trigger the motor 741 to change the spoiler from the stowed position to the deployed position when the window is opened to the first opening. The first opening degree of the vehicle window can be set according to needs and wind noise conditions, so that the movement of the spoiler does not need to be triggered when the vehicle window is opened to a certain degree or the wind noise is small. Or in another embodiment, the spoiler may not be triggered to move when the window is jogged, e.g., opened or the glass is lowered to a depth that does not exceed the height 1/6 of the window as a whole. In a further embodiment, the trigger condition for spoiler movement comprises a user command, e.g. a user may open a window by means of a button or voice command, and the controller may comprise executable instructions which are programmable to simultaneously trigger rotation of the window lifter motor and rotation of the spoiler drive or motor.

The trigger condition for spoiler movement may also include other factors. In yet another embodiment, wherein the controller is configured to further receive one or more of a vehicle speed signal, a noise level signal, an occupant command, and a window position signal to determine whether to trigger spoiler movement. In some embodiments, the controller is disabled to move the spoiler when the vehicle speed is below a threshold. For example when the vehicle speed is below 20 km per hour. In other embodiments, the controller may be enabled to drive the spoiler in motion when the vehicle speed is above a certain threshold, such as 40 kilometers per hour. The skilled person can adjust the relevant parameters based on the design of the vehicle. In still other embodiments, the spoiler position may be adjusted based on an occupant's voice or a push-button switch or the like.

In yet another embodiment, the movement of the spoiler may be adjusted based on the position signal of the other window. The spoiler may not be activated, for example, when it is detected that both diagonal windows are open.

If the determination at step 904 is "NO," the method 900 returns to step 902. If the determination at step 904 is "yes," the method 900 proceeds to step 906 and the spoiler deployment position is moved at step 906. Subsequently, at 908, method 900 determines whether a spoiler deployment position needs to be modified. In one embodiment, the controller is configured to further receive one or more of a vehicle speed signal, a noise level signal, an occupant command, and a window position signal to adjust a deployed position of the spoiler. If the determination at step 904 is "NO," the method 900 proceeds to step 912. If the determination at step 904 is "yes," the method 900 proceeds to step 910 where, at step 910, the controller may control the drive mechanism to adjust the spoiler position such that the spoiler is open more or less. In one embodiment, in some vehicles, an active noise reduction system for active noise reduction has been configured in the vehicle, wherein noise level signals may be collected by an in-vehicle microphone and processed by a processor and controller to determine the deployed position of the spoiler, such as may cause the spoiler to protrude more relative to the surface of the substrate when high wind noise is detected.

At step 912, the controller may be further configured to detect a stow condition of the spoiler, the stow condition including, but not limited to, a vehicle speed signal, a noise level signal, an occupant command, a window position signal, a stop command, arrival at a particular location, and the like. And then, if the stow condition is satisfied, the method 900 proceeds to step 914 where the method operates the spoiler to the stowed position at step 914. In one embodiment, the method 900 may trigger the motor to move the spoiler to the stowed position upon receipt of a window closing command. In another embodiment, the spoiler is stowed when a vehicle speed below a threshold is received, or the vehicle is parked, or a passenger command is received. In yet another embodiment, the spoiler may be commanded to close when the vehicle is detected to reach the target location.

Although

steps

908 and 910 are shown with respect to the angular correction in the above example, it is to be understood that this is not required, and that the spoiler may be stowed at 914 upon detection of a close condition after being triggered at step 906.

Of course, in the above-described embodiments, the motor is explained as an example of the driving device, and the driving device may be driven by another suitable driving mechanism. In one embodiment, the spoiler assembly comprises a trigger mechanism which is linked with the window glass, the trigger mechanism is triggered to be opened when the window glass is lowered to the first position, and the trigger mechanism is triggered to be retracted when the window glass is raised to the first position.

With continued reference to fig. 10, the results of the detection comparison of the wind noise value (indicated by dots) with the spoiler and the wind noise value (indicated by crosses) of the front window of the vehicle without the spoiler are shown. The spoiler is the spoiler shown in fig. 2. Wherein the vertical axis represents the decibel amount of the wind noise value (Trob Level), and the horizontal axis represents the vehicle speed (kilometers per hour) and the Yaw angle (Yaw), Yaw or Yaw angle. Wherein the broken line of the box point represents a preset acceptable wind noise threshold value. The actual wind noise value is expected to be below the preset wind noise threshold value. As shown, as the speed increases, at the illustrated speed range of about 70 kilometers per hour to about 118 kilometers per hour, the noise value for the spoiler is not set above the threshold line, and the test value for the spoiler is set to be substantially maintained below or near the threshold line. Whereas at a certain yaw or yaw angle, for example 5 degrees, 10 degrees, and at a vehicle speed of 100 km/h, it can be seen that the test results for the vehicle with the spoiler also show a noise reduction effect, compared to a vehicle without the spoiler exceeding the threshold.

One or more embodiments of the present application provide a spoiler assembly for a front portion of a front window of a vehicle. In the retracted position, the first surface of the spoiler is substantially flush with the outer surface of the decorative plate, and in the extended position, the first surface of the spoiler protrudes from the outer surface of the decorative plate, so that a good air guiding or spoiler effect is achieved. The spoiler may have any suitable shape, angle, provided that the spoiler is shaped and positioned to alter the distribution of airflow during vehicle travel in the deployed position to reduce noise when the front window is open. The spoiler can be integrated into a trim panel of a front window or into a vehicle mirror housing.
