Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] The following describes in detail, with reference to the accompanying drawings, the window spoiler 10, the door assembly 100, and the vehicle according to embodiments of the present invention.

[0026] Reference Figures 1-5 As shown, the vehicle window spoiler 10 according to a first aspect embodiment of the present invention includes: a spoiler 1, the spoiler 1 being mounted on the front window frame 30 on the front side of the vehicle window glass 20, wherein the size of the spoiler 1 protruding outward from the front window frame 30 in the width direction of the vehicle is adjustable, and / or, in the height direction of the vehicle, the position of the spoiler 1 protruding outward from the front window frame 30 is adjustable.

[0027] Specifically, the window spoiler 10 can be installed at the vehicle window position. The window includes a window frame and a retractable window glass 20. The area of ​​the window frame located in front of the window glass 20 is called the front window frame 30. When the window glass 20 is lowered to open the window, the spoiler 1 of the window spoiler 10 can extend outward from the front window frame 30 in front of the window glass 20 to guide the airflow smoothly through the window opening, reduce the impact of airflow on the window opening position, improve the aerodynamic performance of the vehicle when the window is open, and reduce the noise generated by wind vibration.

[0028] In the width direction of the vehicle, the size of the spoiler 1 protruding outward from the front window frame 30 is adjustable. That is, in the left and right direction, the size of the spoiler 1 protruding outward from the front window frame 30 is adjustable. For example, when the vehicle speed is slow or the window glass 20 drops slightly, the size of the spoiler 1 protruding outward from the front window frame 30 can be smaller to reduce the wind resistance of the spoiler 1. When the vehicle speed is fast or the window glass 20 drops significantly, the size of the spoiler 1 protruding outward from the front window frame 30 can be larger to reduce the noise generated by wind vibration.

[0029] In the height direction of the vehicle, the position of the spoiler 1 protruding outward from the front window frame 30 is adjustable. That is to say, in the vertical direction, the position of the spoiler 1 protruding outward from the front window frame 30 is adjustable. For example, when the window glass 20 is lowered by a small amount, the spoiler 1 can protrude in the upper area of ​​the front window frame 30. When the window glass 20 is lowered by a large amount, the spoiler 1 can protrude in the middle and upper areas of the front window frame 30. The spoiler 1 can be at the same height as the area where the window is open in order to reduce the noise generated by wind vibration when the vehicle is in motion.

[0030] It should be noted that at least one of the dimensions and positions of the spoiler 1 protruding from the front window frame 30 is adjustable. The adjustment of the dimensions and positions of the spoiler 1 protruding from the front window frame 30 can be achieved by driving the spoiler 1 to move or rotate through a drive device, or by designing a corresponding matching structure between the spoiler 1 and the window glass 20, utilizing the elastic deformation of the spoiler 1 itself. Alternatively, multiple snap-fit ​​holes at different positions can be provided on the front window frame 30, and the dimensions and positions of the spoiler 1 can be adjusted by manually adjusting the snap-fit ​​holes installed at different positions.

[0031] In addition, when the windows are closed, the spoiler 1 does not protrude from the front window frame 30 to avoid the spoiler 1 causing additional wind resistance and noise to the vehicle.

[0032] According to an embodiment of the present invention, the windshield spoiler 10 has a spoiler 1 installed on the front window frame 30 on the front side of the windshield glass 20. The size and position of the spoiler 1 protruding from the front window frame 30 are adjustable to reduce the impact of airflow on the open window position, improve the aerodynamic performance of the vehicle when the window is open, and reduce the noise generated by wind vibration.

[0033] In some embodiments of the present invention, reference is made to... Figures 1-3 As shown, the size of the spoiler 1 protruding from the front window frame 30 is positively correlated with the descent distance of the window glass 20. That is, the greater the descent distance of the window glass 20, the larger the window opening, and the larger the size of the spoiler 1 protruding from the front window frame 30, thus significantly reducing wind vibration intensity, reducing wind-generated noise, and improving vehicle comfort. Conversely, the smaller the descent distance of the window glass 20, the smaller the window opening, and the smaller the size of the spoiler 1 protruding from the front window frame 30, thus reducing wind-generated noise while also reducing the wind resistance of the spoiler 1 itself, improving vehicle fuel economy.

[0034] In some embodiments of the present invention, reference is made to... Figures 1-3 As shown, the position of the spoiler 1 protruding from the front window frame 30 corresponds to the position where the window glass 20 and the front window frame 30 separate. That is, when the window glass 20 is lowered to form an opening, the position of the spoiler 1 protruding from the front window frame 30 corresponds to the position of the window opening in the vehicle's height direction. In other words, the position of the spoiler 1 protruding from the front window frame 30 and the position of the window opening are at the same height in the vertical direction, so that the spoiler 1 can guide the airflow directly in front of the window opening, thereby improving the spoiler 1's effective airflow guidance at the window opening position, reducing wind vibration intensity, and reducing noise transmission into the vehicle.

[0035] In some embodiments of the present invention, reference is made to... Figures 2-5 As shown, the window spoiler 10 also includes: a mounting base 2, which is fixed to the front window frame 30. The mounting base 2 has a mounting groove 21. In the width direction of the vehicle, the mounting groove 21 is located inside the window glass 20, and the spoiler 1 is movably inserted through the mounting groove 21.

[0036] Specifically, the mounting base 2 can be connected to the front window frame 30 via fasteners, welding, or other means. The spoiler 1 can be indirectly mounted to the front window frame 30 via the mounting base 2. The mounting base 2 has a mounting groove 21, which is located inside the window glass 20 in the left-right direction. The spoiler 1 is movably inserted through the mounting groove 21, meaning that the spoiler 1 can move along the inner wall of the mounting groove 21 in the left-right direction to extend or retract from the mounting groove 21. When the window glass 20 is closed, the spoiler 1 can retract into the mounting groove 21 and be located on the side of the window glass 20 facing the inside of the vehicle to avoid additional wind resistance. When the window glass 20 is open, the spoiler 1 can extend out of the mounting groove 21 and protrude from the window opening to protrude from the front window frame 30, thereby reducing noise generated by wind vibration.

[0037] It is understandable that the window spoiler 10 can be installed on the vehicle by detaching and assembling the mounting bracket 2 and the front window frame 30. The window spoiler 10 can be directly installed on the vehicle by the OEM at the factory, or it can be modified on the finished vehicle as a modification part. The mounting bracket 2 can be the same color as the front window frame 30, so that the mounting bracket 2 and the front window frame 30 can be considered as one unit.

[0038] In some embodiments of the present invention, reference is made to... Figure 4 As shown, an elastic element 3 is provided between the spoiler 1 and the bottom wall of the mounting groove 21. The elastic element 3 can be compressed in the width direction of the vehicle. Both ends of the elastic element 3 are connected to the spoiler 1 and the bottom wall of the mounting groove 21, respectively. The elastic element 3 can apply a force to the spoiler 1, causing it to protrude outwards from the front window frame 30. When the window 20 is closed, the elastic element 3 causes the spoiler 1 to abut against the window 20. When the window 20 is lowered to open the window, the elastic element 3 can cause the spoiler 1 to move outwards or flip, thus protruding outwards from the front window frame 30. The elastic element 3 enables the spoiler 1 to automatically pop out. Its structure is simple and low-cost. Optionally, the elastic element 3 can be a coil spring or a gas spring.

[0039] In some embodiments of the present invention, reference is made to... Figure 4 and Figure 5 As shown, the spoiler 1 includes a baffle 11 and an outer keel 12. The outer keel 12 includes an upper flange section 121, a middle section 122 and a lower connecting section 123 connected in sequence. The middle section 122 is connected to the side of the baffle 11 facing the window glass 20. The groove of the mounting groove 21 corresponds to the middle section 122. The upper flange section 121 is movably disposed in the mounting groove 21. The lower connecting section 123 is hinged or riveted to the mounting groove 21.

[0040] Specifically, the outer keel 12 can strengthen and limit the baffle 11. The upper flange section 121 of the outer keel 12 can be movably disposed in the mounting groove 21. The upper flange section 121 can prevent the upper end of the spoiler 1 from coming out of the mounting groove 21. The middle section 122 is connected to the side of the baffle 11 facing the window glass 20. That is, the middle section 122 can wrap the side of the baffle 11 facing the outside of the vehicle to improve the strength and wear resistance of the baffle 11 and reduce the wear of the baffle 11 when the window glass 20 is raised and lowered. The lower connecting section 123 is hinged or riveted to the mounting groove 21 to reduce the risk of the spoiler 1 coming loose.

[0041] In some embodiments, refer to Figure 5As shown, the outer keel 12 itself can have a certain elasticity, and its lower connecting section 123 can be riveted to the mounting groove 21. The outer keel 12 has a tendency to flip outward around the riveting point, so that when the window glass 20 is lowered, the outer keel 12 can drive the baffle 11 to move outward, so that the spoiler 1 protrudes out of the front window frame 30. When the window glass 20 is raised, the window glass 20 can press the outer keel 12 back inward, so that the spoiler 1 is retracted inside the window glass 20.

[0042] In other embodiments, reference is made to Figure 4 As shown, the lower connecting section 123 of the outer keel 12 can be hinged to the mounting groove 21. Through the elastic element 3 between the spoiler 1 and the bottom wall of the mounting groove 21, the spoiler 1 has a tendency to rotate outward around the hinge axis, so as to realize the linkage between the extension and retraction of the spoiler 1 and the lifting and lowering of the window glass 20.

[0043] It should be noted that the lower connecting section 123 can also be hinged or riveted to the inner panel of the door (metal sheet metal) to further reduce the risk of the spoiler 1 coming loose.

[0044] In some embodiments of the present invention, the outer keel 12 is made of metal to ensure its structural strength, such as stainless steel or aluminum alloy. The outer keel 12 has a certain thickness in the length direction (i.e., the front-to-back direction) of the vehicle. At least a portion of the upper flange section 121, the lower connecting section 123 and the middle section 122 of the outer keel 12 abuts against the side wall of the mounting groove 21 to avoid the spoiler 1 from deflecting under wind load.

[0045] Optionally, the rigidity of the outer keel 12 is greater than that of the baffle 11, and the baffle 11 is made of plastic to reduce the weight and cost of the baffle 11.

[0046] In some embodiments of the present invention, reference is made to... Figure 4 and Figure 5 As shown, the width of the spoiler 1 gradually increases from the lower end to the upper end, meaning that the spoiler 1 is wider at the top and narrower at the bottom. The width of the spoiler 1 is its dimension in the left-right direction. When the spoiler 1 is wider at the top and narrower at the bottom, the outer surface of the spoiler 1 facing the window glass 20 can form a guiding cooperation with the raising and lowering of the window glass 20, so that the spoiler 1 and the window glass 20 can be linked together. Its structure is simple, low in cost, and highly reliable.

[0047] Reference Figures 1-3As shown, when the window glass 20 is lowered, the contact point between the window glass 20 and the spoiler 1 gradually decreases. Because the spoiler 1 is wider at the top and narrower at the bottom, it can flip outwards under its own elasticity or the action of the elastic element 3. Therefore, as the window glass 20 decreases, the size of the spoiler 1 protruding from the front window frame 30 gradually increases, with the upper part of the spoiler 1 protruding from the front window frame 30 before the lower part, so that the area of ​​the spoiler 1 protruding from the front window frame 30 is at the same height as the area where the window is open. When the window glass 20 is raised, the movement of the spoiler 1 is the reverse of the above process.

[0048] It should be noted that the front window frame 30 can be the triangular window frame of the door or the A-pillar of the vehicle. The front window frame 30 can be located on the front side of the window glass 20.

[0049] Experimental verification shows that the window spoiler 10 can control the wind vibration when the window is open to below 115dB, where the user's perception of wind vibration is weak. The width of the spoiler 1 can be simulated and designed according to different vehicle models. The greater the wind vibration intensity, the greater the width of the spoiler 1, that is, the larger the size of the spoiler 1 that can extend out of the front window frame 30. Optionally, the width of the spoiler 1 is between 2mm and 20mm.

[0050] Reference Figures 1-5 As shown, the door assembly 100 according to a second aspect embodiment of the present invention includes the window spoiler 10 of the above embodiment.

[0051] Specifically, the door assembly 100 also includes a window glass 20 and a front window frame 30. The front window frame 30 is located in front of the window glass 20. The window glass 20 can be raised and lowered relative to the front window frame 30. The window spoiler 10 is installed on the front window frame 30.

[0052] According to an embodiment of the present invention, the door assembly 100 has a spoiler 1 mounted on the front window frame 30 on the front side of the window glass 20. The size and position of the spoiler 1 protruding from the front window frame 30 are adjustable to reduce the impact of airflow on the open window position, improve the aerodynamic performance of the vehicle when the window is open, and reduce the noise generated by wind vibration.

[0053] According to a third aspect of the present invention, a vehicle includes the door assembly 100 of the above-described embodiments.

[0054] According to an embodiment of the present invention, a spoiler 1 is mounted on the front window frame 30 on the front side of the window glass 20. The size and position of the spoiler 1 protruding from the front window frame 30 are adjustable to reduce the impact of airflow on the open window position, improve the aerodynamic performance of the vehicle when the window is open, and reduce the noise generated by wind vibration.
