[0031] The utility model provides a tail wing assembly and vehicle to improve the wind noise produced by the hollow tail wing. The following will be described in detail in combination with specific embodiments.
[0032] As shown in Figure 1 and Figure 2 The utility model provides a tail wing assembly, including tail wing body 1 and sliding plate 2, tail wing body 1 is used to install on back door trim 3 and with back door trim 3 defines hollow passageway 4, sliding plate 2 is slidably installed in tail wing body 1 along the direction towards or away from back door trim 3 to be used to open or close hollow passageway 4.
[0033] It should be noted that for the direction towards back door trim 3, it can be the direction perpendicular to back door trim 3, or the direction with the surface of back door trim 3 at an acute angle, as long as the sliding plate 2 slides along the direction to finally realize the closure of the hollow passageway 4, in a specific embodiment, the direction towards back door trim 3 is Figure 2 The extension direction of the connecting line of the opening 12 in the middle and the slot 31.
[0034] It should be noted that for the sliding of the sliding plate 2 to open or close the hollow passageway 4, the opening or closing of the hollow passageway 4 can be selected according to the vehicle speed, such as driving the sliding plate 2 to slide to close the hollow passageway 4 when the vehicle speed is greater than 30kph, and driving the sliding plate 2 to slide to open the hollow passageway 4 when the vehicle speed is less than or equal to 30kph.
[0035] It should be noted that the utility model does not limit the specific size of the sliding plate 2, as long as the sliding plate 2 can close the hollow passageway 4 when contacting the back door trim 3.
[0036] In the embodiment, the slide plate 2 is added on the tail wing body 1, and the slide plate 2 is slidable relative to the tail wing body 1 in the direction towards or away from the back door trim 3, so that the slide plate 2 can open or close the hollow channel 4 between the tail wing body 1 and the back door trim 3 in the sliding stroke. Thus, when the vehicle travels at a high speed, for example, the vehicle speed is greater than 30 kph, the slide plate 2 can be driven to slide to close the hollow channel 4, thereby avoiding the noise caused by the high-speed airflow flowing through the hollow channel 4, improving the wind noise of the hollow tail wing, and improving the user driving experience.
[0037] Optionally, as shown in Figure 1 and Figure 2 , the tail wing body 1 is provided with a cavity 11 and an opening 12 communicating with the cavity 11, the opening 12 is located at the end of the tail wing body 1 close to the back door trim 3; the slide plate 2 is slidably inserted into the opening 12, and the slide plate 2 is used to slide into or out of the cavity 11 through the opening 12 to correspondingly open or close the hollow channel 4.
[0038] It should be noted that the tail wing body 1 generally has a strip shape and extends in the width direction of the vehicle, so the hollow channel 4 defined by the tail wing body 1 and the back door trim 3 is generally also strip-shaped, and the slide plate 2 is generally a strip-shaped plate structure. In order to facilitate the sliding insertion of the slide plate 2 into the opening 12, the opening 12 should also be generally long strip-shaped.
[0039] It can be understood that the slide plate 2 is used to slide into or out of the cavity 11 through the opening 12 to correspondingly open or close the hollow channel 4, that is, referring to Figure 1 and Figure 2 , when the slide plate 2 slides into the cavity 11 through the opening 12, the slide plate 2 is hidden in the cavity 11, so that the hollow channel 4 can be opened, referring to Figure 3 and Figure 4 , when the slide plate 2 slides out of the cavity 11 through the opening 12, the slide plate 2 is exposed to the cavity 11, so that the hollow channel 4 can be closed.
[0040] In the optional embodiment, the slide plate 2 is slidably inserted into the opening 12 to realize the slidable installation of the slide plate 2 relative to the tail wing body 1. When the slide plate 2 slides into the cavity 11 through the opening 12, the hollow channel 4 can be correspondingly opened. When the slide plate 2 slides out of the cavity 11 through the opening 12, the hollow channel 4 can be correspondingly closed. Since the slide plate 2 will only slide out of the cavity 11 to close the hollow channel 4 when needed, this reduces unnecessary physical protrusions of the tail wing when not driving at high speed, avoiding the impact of physical protrusions on the performance of the tail wing.
[0041] Optionally, the inner cavity wall of the cavity 11 is provided with a sliding groove; the slide plate 2 is in sliding cooperation with the sliding groove.
[0042] It should be noted that the sliding groove is formed in a direction towards the back door trim 3, that is, the length direction of the sliding groove is the direction towards the back door trim 3, so as to ensure that the sliding direction of the sliding plate 2 relative to the sliding groove is consistent with the sliding direction of the sliding plate 2 relative to the opening 12.
[0043] It should be noted that two sliding grooves can be arranged, which are arranged on the inner cavity wall of the cavity 11 and located at two sides of the sliding plate 2 respectively, and the two ends of the sliding plate 2 are respectively in sliding fit with the two sliding grooves.
[0044] In the optional embodiment, the sliding plate 2 is in sliding fit with the sliding groove by arranging the sliding groove on the inner cavity wall of the cavity 11 in a direction towards the back door trim 3, so that when the sliding plate 2 slides relative to the opening 12, the sliding plate 2 also slides along the sliding groove. The sliding fit between the sliding plate 2 and the sliding groove can provide a guide for the movement of the sliding plate 2 towards the back door trim 3, help the sliding plate 2 maintain the straightness of the sliding, avoid the deflection of the sliding plate 2 during the sliding, and effectively seal the hollow channel 4.
[0045] Optionally, as shown in Figure 2 and Figure 4 , the opening 12 is provided with a sealing element in contact with the sliding plate 2.
[0046] It should be noted that the sealing element can be completely sealed with the sliding plate 2 along the circumference of the opening 12, or can be partially sealed, for example, when the sealing element is completely sealed along the circumference, the sealing element can be selected as a sealing ring, and for example, when the sealing element is partially sealed, the sealing element can be selected as a sealing strip.
[0047] In the optional embodiment, by arranging the sealing element in contact with the sliding plate 2 at the opening 12, the sealing between the sliding plate 2 and the opening 12 can be improved, so as to avoid that there is a large gap between the two, which causes airflow to still flow through the gap and produce certain noise, thereby improving the wind noise.
[0048] Optionally, as shown in Figure 2 and Figure 4 , the sealing element includes an annular sealing ring 121 formed in a circumferential direction of the opening 12, and an inner circumferential surface of the annular sealing ring 121 is in close contact with the sliding plate 2.
[0049] It should be noted that the annular sealing ring 121 is formed in a circumferential direction of the opening 12, that is, the shape of the annular sealing ring 121 is matched with the shape of the opening 12, so as to facilitate the sealing element to completely seal the sliding plate 2 along the circumference of the opening 12.
[0050] In the alternative embodiment, the sealing member comprises an annular sealing ring 121 formed along the circumference of the opening 12, and the inner circumferential surface of the annular sealing ring 121 is in close contact with the sliding plate 2, thereby ensuring the circumferential sealing between the sliding plate 2 and the opening 12, more effectively eliminating the gap between the sliding plate 2 and the opening 12, and facilitating better improvement of wind noise.
[0051] Optionally, as shown in Figure 5 , the front side 13 of the spoiler body 1 is upwardly inclined relative to the back door trim 3, and the included angle between the sliding plate 2 and the front side 13 of the spoiler body 1 is less than or equal to 30°.
[0052] It should be noted that the front side 13 of the spoiler body 1 refers to the side of the spoiler body 1 facing the front of the vehicle, which is used for windward setting; in this embodiment, the front side 13 not only faces the front of the vehicle, but also faces the top of the vehicle, and is inclined relative to the back door trim 3 as a whole, which can guide the airflow flowing along the back door trim 3 to the rear of the vehicle. In addition, the included angle between the sliding plate 2 and the front side 13 of the spoiler body 1 refers to the included angle between the sliding plate 2 and the front side 13 in the cross section of the spoiler assembly perpendicular to the vehicle width direction. It should be noted that the included angle between the sliding plate 2 and the front side 13 of the spoiler body 1 is less than or equal to 30°, for example, it can be 0°, 15° or 30°, and the included angle is preferably 0°. Referring to Figure 5 , the included angle between the sliding plate 2 and the upper side 13 of the spoiler body 1 is angle θ.
[0053] In the alternative embodiment, the included angle between the sliding plate 2 and the front side 13 of the spoiler body 1 is less than or equal to 30°, which can make the angle of the sliding plate 2 when closing the hollow passage 4 closer to the angle of the front side 13 of the spoiler body 1, and the two are more gentle, which is beneficial to guide the airflow and improve wind noise.
[0054] Optionally, as shown in Figure 5 , the front side 13 of the spoiler body 1 is upwardly inclined relative to the back door trim 3, and the distance between the sliding plate 2 and the front end point of the front side 13 of the spoiler body 1 is less than or equal to 10mm.
[0055] It should be noted that the front end point of the sliding plate 2 and the front side 13 of the spoiler body 1 refers to the vertical distance between the front end point of the front side 13 and the sliding plate 2 in the cross section of the spoiler assembly perpendicular to the vehicle width direction. It should be noted that the front end point of the front side 13 is the end point of the front side 13 closest to the front of the vehicle. It should be noted that the distance between the sliding plate 2 and the front end point of the front side 13 of the spoiler body 1 is less than or equal to 10mm, for example, it can be 5mm or 10mm. Referring to Figure 5 , the distance between the sliding plate 2 and the front end point of the front side 13 of the spoiler body 1 is distance d.
[0056] In the optional embodiment, the distance between the sliding plate 2 and the front end point of the front side 13 of the tail wing body 1 is less than or equal to 10 mm, so that the sliding plate 2 is closer to the front end of the tail wing body 1, and the wind noise problem caused by the large cavity 11 in front of the sliding plate 2 due to the rear position of the sliding plate 2 is avoided.
[0057] Optionally, the tail wing assembly further comprises a linear motor arranged on the tail wing body 1, and the linear motor is drivingly connected with the sliding plate 2 and used to drive the sliding plate 2 to slide.
[0058] It should be noted that the linear motor is drivingly connected with the sliding plate 2 to drive the sliding plate 2 to slide in the direction towards the back door trim 3, and the linear motor can be controlled to act by a controller to control the sliding plate 2 to slide and thus open or close the hollow passage 4. Specifically, the controller can control the linear motor to act to make the sliding plate 2 slide to close the hollow passage 4 when the vehicle speed is greater than 30 kph, and control the linear motor to act to make the sliding plate 2 slide to open the hollow passage 4 when the vehicle speed is less than or equal to 30 kph.
[0059] In the optional embodiment, the linear motor is drivingly connected with the sliding plate 2 to drive the sliding plate 2 to slide in the direction towards or away from the back door trim 3, so that the linear motor can drive the sliding plate 2 to slide to correspondingly open or close the hollow passage 4 at different vehicle speeds, the automatic opening and closing of the hollow passage 4 is realized, the hollow passage 4 can be automatically closed when the vehicle travels at a too high speed, the airflow generated by the too high speed of the vehicle is prevented from flowing through the hollow passage 4 to cause wind noise, and the wind noise of the hollow tail wing is greatly improved.
