[0033] like Figures 1 to 4 As shown, the present application provides an electric rear wing 100 for an automobile, which is installed at the rear part of the automobile, such as a trunk lid or a rear door.

[0034] Specifically, please refer to Figure 5 The electric rear wing 100 of the automobile includes a rear wing panel 10 and a lifting mechanism 20. The rear wing panel 10 is mounted on the lifting mechanism 20 and can be deployed (eg, Figure 1 as shown) or folded (as shown Figure 2 As shown), the electric rear wing 100 of the automobile can be opened or closed. The lifting mechanism 20 includes a lifting unit 21 and a support plate 22. The support plate 22 is mounted on the lifting unit 21, and the rear wing panel 10 is mounted on the support plate 22. In addition, along the length direction x of the automobile, the length of the rear wing panel 10 is L1, the length of the support plate 22 is L2, and 0.3L1≤L2≤0.6L1. In this way, there can be sufficient contact area between the support plate 22 and the rear wing panel 10, thereby effectively improving the connection strength and stability between the two.

[0035] It should be explained that the value of L2 cannot be too small or too large. If it is too small, the contact area between the tail wing panel 10 and the support panel 22 cannot be guaranteed; if it is too large, it needs to provide a large enough space after folding, which makes folding complicated and occupies too much space. Therefore, 0.3L1≤L2≤0.6L1, which can not only ensure that there is enough connection area between the two and ensure the stability of the connection; but also the space occupied by the support panel 22 is not too large, which is convenient for design and folding.

[0036] In one embodiment, the size of the rear wing panel 10 is generally large, and its length x in the length direction of the car is generally between 250 mm and 350 mm, that is, 250 mm ≤ L1 ≤ 350 mm. Therefore, the rear wing panel 10 is also called a large-size rear wing panel.

[0037] Here, the value of L1 can be 250mm, 260mm, 270mm, 280mm, 290mm, 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, etc. Of course, within its numerical range, the value of L1 can also be selected according to actual needs.

[0038] Furthermore, the value of L2 may be 0.3L1, 0.35L1, 0.4L1, 0.45L1, 0.5L1, 0.55L1, 0.6L1. Of course, within its numerical range, the value of L2 may also be selected according to actual needs.

[0039] For example, in the length direction x of the car, when the value of L1 is 300 mm, the value of L2 can be 90 mm, 120 mm, 150 mm, etc. When the value of L1 is 278 mm, the value of L2 can be 100 mm, 105 mm, 130 mm, etc.

[0040] Preferably, L1 and L2 satisfy: 0.35L1≤L2≤0.5L1. In this way, within this range, not only can the stability of the connection between the support plate 22 and the tail wing plate 10 be effectively guaranteed, but the size of the support plate 22 is also relatively small, and its spatial layout is more reasonable.

[0041] In one embodiment, if Figure 6 As shown, the tail wing panel 10 has a first bonding surface 11, and the support panel 22 has a second bonding surface 221, and the first bonding surface 11 and the second bonding surface 221 are bonded to each other. In this way, the support panel 22 and the tail wing panel 10 are connected by a surface bonding method, which further improves the stability of the connection between the tail wing panel 10 and the support panel 22.

[0042] Preferably, the first bonding surface 11 and the second bonding surface 221 are both configured as planes.

[0043] like Figure 3 As shown, the electric rear wing 100 of the automobile further includes a decorative panel 30 and a driving mechanism 40. The decorative panel 30 is used to be installed on the frame of the vehicle body (not shown). The driving mechanism 40 and the lifting unit 21 are respectively installed on the decorative panel 30, and the driving mechanism 40 is connected to the lifting unit 21 to drive the lifting unit 21 to perform lifting / lowering movement in the vertical direction z of the automobile, thereby driving the rear wing panel 10 to unfold or fold. Here, the lifting unit 21 can be a telescopic rod structure, a connecting rod structure, etc., and its specific structure is not described in detail here.

[0044] In one embodiment, please continue to refer to Figure 3 The driving mechanism 40 includes a driving member 41 and a transmission shaft 42. The driving member 41 is mounted on the decorative panel 30. The transmission shaft 42 is connected to the driving member 41, and the other end is connected to the lifting unit 21. In this way, the driving member 41 moves to drive the transmission shaft 42 to rotate, and then the transmission shaft 42 drives the lifting unit 21 to rise and fall in the vertical direction z, thereby driving the tail wing panel 10 to unfold or fold.

[0045] Specifically, the transmission shaft 42 is configured as a flexible shaft. In this way, the structural characteristics of the flexible shaft itself are used to compensate for the installation or transmission error between the driving member 41 and the transmission shaft 42, effectively improving the accuracy of the transmission. Of course, in other embodiments, the transmission shaft 42 can also be configured as a rigid shaft.

[0046] For further information, please refer to Figure 3 The driving mechanism 40 also includes a coupling 43, and the transmission shaft 42 and the driving member 41 are connected through the coupling 43, that is, the driving force of the driving member 41 is transmitted to the transmission shaft 42 through the coupling 43, thereby driving the transmission shaft 42 to rotate.

[0047] In one embodiment, please continue to refer to Figure 3 In the width direction y of the automobile, the number of the lifting mechanisms 20 is configured to be two, and the two lifting mechanisms 20 are spaced apart in the width direction y. The driving member 41 is arranged between the two lifting mechanisms 20 and is simultaneously connected to the two lifting mechanisms 20, so as to synchronously drive the two lifting mechanisms 20.

[0048] It should be explained that the two lifting mechanisms 20 can effectively support the tail wing panel 10 and improve the stability of the lifting of the tail wing panel 10. At the same time, the use of a driving member 41 to drive the two lifting mechanisms 20 at the same time can well ensure the stability and synchronization of the movement of the tail wing panel 10.

[0049] Furthermore, the two lifting mechanisms 20 are spaced apart in the width direction y, which is large for the span of the driving member 41 and is not conducive to the transmission of the power of the driving member 41. Therefore, here, the transfer is achieved through a flexible shaft, so that the power of the driving member 41 is transmitted, which effectively improves the stability of the power output of the driving member 41 and the reliability of the movement of the tail wing panel 10.

[0050] like Figure 6 and Figure 7 As shown, the electric rear wing 100 of the automobile also includes an adjustment mechanism 50, which is installed on the support plate 22 and is used to adjust the position of the rear wing panel 10 in the vertical direction z of the automobile. It should be noted that after the rear wing panel 10 is installed, there may sometimes be a height difference (face difference) between it and the surrounding components (such as taillights or trunk panels), thereby affecting the overall appearance and shape of the automobile. Therefore, here, the position of the rear wing panel 10 in the vertical direction z of the automobile is adjusted by setting an adjustment mechanism 50. When a face difference occurs, the rear wing panel 10 can be raised / lowered in the vertical direction z by the adjustment mechanism 50, thereby avoiding a height difference between the rear wing panel 10 and the surrounding components, so that the rear wing panel 10 and the surrounding components are adapted to each other.

[0051] For details, please continue to refer to Figure 7 The adjustment mechanism 50 includes a fixing sleeve 51 and an adjusting sleeve 52. A first connecting hole 222 is provided on the support plate 22. The fixing sleeve 51 is provided at the first connecting hole 222 and connected to the support plate 22, and an internal thread is provided on the inner wall of the fixing sleeve 51. An external thread is provided on the outer wall of the adjusting sleeve 52. One end of the adjusting sleeve 52 passes through the fixing sleeve 51 and the first connecting hole 222 in sequence and abuts against the tail wing board 10 to form a support for the tail wing board 10, and the external thread and the internal thread are threadedly connected. When the height of the tail wing board 10 needs to be adjusted, it is only necessary to rotate the adjusting sleeve 52 so that the adjusting sleeve 52 can be extended relative to the fixing sleeve 51, thereby changing the abutment height between the adjusting sleeve 52 and the tail wing board 10, that is, the position adjustment of the tail wing board 10 in the vertical direction z direction is realized.

[0052] Furthermore, the rear wing plate 10 is provided with a second connection hole 12 corresponding to the first connection hole 222; the electric rear wing 100 for automobiles further includes a locking member 60 and a matching member 70; one end of the locking member 60 is passed through the adjustment sleeve 52 and the second connection hole 12 in sequence and connected to the matching member 70, and the other end is against the adjustment sleeve 52 to connect the support plate 22 with the rear wing plate 10. In this way, the rear wing plate 10 and the support plate 22 are fixed, and the adjustment mechanism 50 and the locking member 60 are organically combined, making the structure more compact; at the same time, the two structures share the first connection hole 222 and the second connection hole 12, omitting the step of opening redundant holes on the support plate 22 and the rear wing plate 10, making the processing and installation costs lower.

[0053] Here, the locking member 60 may be a bolt, and the corresponding matching member 70 may be a nut. Of course, the locking member 60 may also be other structures, such as a pin, and the corresponding matching member 70 is a latch. After one end of the pin is penetrated by the adjustment sleeve 52 and the second connecting hole 12, the latch is inserted into the pin, thereby forming a limit.

[0054] The present application also provides a car, which includes the car electric rear wing 100 in any of the above embodiments.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
