The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0034] like Figure 1 and Figure 2 As shown, the present application provides an electric rear wing 200 for an automobile, which is installed at a rear position in the length direction x of the automobile, such as a trunk lid or a rear door.

[0035] For details, please continue to refer to Figure 1 and Figure 2 The electric rear wing 200 of the automobile includes a rear wing panel 201, an electric rear wing lifting mechanism 100 and a driving mechanism 202. The rear wing panel 201 is installed on the electric rear wing lifting mechanism 100, and the driving mechanism 202 is connected to the driving mechanism 202 to drive the electric rear wing lifting mechanism 100 to perform an ascending / descending movement in the vertical direction z of the automobile, thereby driving the rear wing panel 201 to fold or unfold.

[0036] Here, the driving mechanism 202 includes a motor 203 and a driving shaft 204, the driving shaft 204 is connected to the motor 203, and the electric tail lifting mechanism 100 is connected to the driving shaft. In this way, under the drive of the motor 203, the driving shaft 204 drives the electric tail lifting mechanism 100 to rise / fall.

[0037] In one embodiment, if Figures 2 to 6 As shown, the electric tail wing lifting mechanism 100 includes a support base 10, a support plate 20 and a lifting unit 30. The support base 10 is used as a base for carrying and installing various components. The support plate 20 is used to support the tail wing plate 201; the lifting unit 30 is installed on the support base 10 and connected to the support plate 20, and the lifting unit 30 has a folded state (refer to Figure 3 ) and expanded state (reference Figure 5 ), the lifting unit 30 can switch between the folded state and the unfolded state in response to external force, so as to drive the support plate 20 to move up / down relative to the support seat 10, thereby realizing the folding or unfolding of the tail wing panel 201.

[0038] Furthermore, if Figures 3 to 6 As shown, the support seat 10 is provided with a first limiting point 11, a second limiting point 12 and a third limiting point 13, and the support plate 20 is provided with a fourth limiting point 21 and a fifth limiting point 22; when the lifting unit 30 is in the folded state, the lifting unit 30 is respectively limited and abutted against the first limiting point 11 and the second limiting point 12; when the lifting unit 30 is in the unfolded state, the lifting unit 30 is respectively limited and abutted against the third limiting point 13, the fourth limiting point 21 and the fifth limiting point 22. In this way, no matter whether the lifting unit 30 is in the folded state or the unfolded state, it can be limited by the limiting points, thereby avoiding the shaking of the lifting unit 30, and effectively improving the stability of the tail wing plate 201. Here, the lifting unit 30 responds to the external force action, that is, the lifting unit 30 is driven by the driving shaft 204, and switches between the folded state and the unfolded state.

[0039] like Figure 3 and Figure 4 As shown, the support base 10 is provided with a receiving groove 14 having an opening 141, and the folded lifting unit 30 can be partially accommodated in the receiving groove 14 through the opening 141. The first limiting point 11 and the second limiting point 12 are arranged in the receiving groove 14, and the third limiting point 13 is arranged at the opening 141. That is, when the lifting unit 30 is in the folded state, it can be accommodated in the receiving groove 14, thereby reducing the space occupied by the lifting unit 30 and making the overall structure more compact.

[0040] Preferably, the first limiting point 11 and the second limiting point 12 are both located at the bottom of the receiving groove 14 .

[0041] In one embodiment, if Figure 3 As shown, the first limiting point 11 is the bottom of the receiving groove 14. Of course, the first limiting point 11 is not limited to the bottom of the receiving groove 14 itself, and a protrusion can also be set at the bottom of the receiving groove 14 for abutment and limiting.

[0042] Furthermore, a first flexible member 143 is disposed at the bottom of the receiving groove 14, and the first flexible member 143 forms the second limiting point 12. Here, the first flexible member 143 is configured as a relatively soft member such as rubber or silicone. Thus, when the second limiting point 12 is limited and abutted, the first flexible member 143 can buffer the extrusion during the abutment process, and avoid abnormal noise, etc.

[0043] Furthermore, if Figure 4 As shown, two convex portions 15 are arranged at intervals on the groove wall at the opening 141 of the receiving groove 14, and a limiting groove 16 is formed between the two convex portions 15, and the third limiting point 13 is located in the limiting groove 16. That is, the limiting groove 16 can further realize the limiting, thereby improving the reliability of the limiting.

[0044] In one embodiment, if Figure 5 and Figure 6 As shown, the support plate 20 is provided with a third flexible member 23 at the fourth limit point 21 and the fifth limit point 22. Thus, when the lifting unit 30 is abutted and limited at the fourth limit point 21 and the fifth limit point 22, the third flexible member 23 can buffer the extrusion during the abutment process, and avoid abnormal noise and the like.

[0045] Here, the third flexible member 23 is configured as a relatively soft member such as rubber or silica gel.

[0046] Preferably, a convex column 24 is provided on the support plate 20 , and the third flexible member 23 is sleeved on the convex column 24 , so as to form a fourth limiting point 21 .

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the lifting unit 30 includes an active rod 31, a first rod 32, a second rod 33, a third rod 34, a fourth rod 35 and a fifth rod 36; one end of the active rod 31 is hinged to the support seat 10, and the other end is provided with a first abutment point 311; one end of the first rod 32 is hinged to the support seat 10, and the other end is provided with a second abutment point 321 and a third abutment point 322; one end of the second rod 33 is hinged to the active rod 31, and the other end is hinged to the first rod 32; one end of the third rod 34 is hinged to the first rod 32, and the other end is hinged to the support plate 20; the fourth rod 35 is hinged to the support seat 10, the fifth rod 36 is rotatably connected to the second rod 33 and one end of the fifth rod 36 is hinged to the fourth rod 35, and the other end is hinged to the support plate 20, and a fourth abutment point 351 is provided on the fourth rod 35 and / or the fifth rod 36; wherein, with reference to Figure 3 and Figure 4 When the lifting unit 30 is in the folded state, the first abutting point 311 forms an abutting limit with the first limiting point 11, and the fourth abutting point 351 forms an abutting limit with the second limiting point 12. Figure 5 and Figure 6 When the lifting unit 30 is in the unfolded state, the first abutting point 311 abuts against the third limiting point 13, the second abutting point 321 abuts against the fourth limiting point 21, and the third abutting point 322 abuts against the fifth limiting point 22. In this way, the lifting unit 30 is limited in the unfolded state or the folded state through the first abutting point 311, the second abutting point 321, the third abutting point 322 and the fourth abutting point 351.

[0048] Furthermore, a second flexible member 312 is sleeved on one end of the active rod 31 away from the support seat 10. The second flexible member 312 is used to limit and flexibly abut against the first abutment point 311. In this way, the impact force during the abutment process is reduced, thereby reducing abnormal noise and improving the comfort of use.

[0049] like Figure 5 and Figure 6 As shown, the connection between the first rod 32 and the support seat 10 is configured as a transition fit; the connection between the second rod 33 and the active rod 31 and the first rod 32 is configured as a transition fit; the connection between the third rod 34 and the first rod 32 and the support plate 20 is configured as a transition fit; the connection between the fourth rod 35 and the support seat 10 is configured as a transition fit; the connection between the fifth rod 36 and the second rod 33, the fourth rod 35 and the support plate 20 is configured as a transition fit.

[0050] It should be explained that transition fit means that the tolerance zone of the hole overlaps the tolerance zone of the shaft. That is, in the lifting unit 30, the matching clearance between the rod and the support seat, the rod and the support plate, and the rods can be minimized through transition fit, thereby reducing looseness and further improving the stability of the lifting unit 30.

[0051] The present application also provides a car, which includes the car electric rear wing 200 in any of the above embodiments.

[0052] 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.

[0053] 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.
