[0068] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0069] This embodiment relates to an electric tail wing, which comprises a bottom bracket assembly, a decorative cover assembly 2 and a tail wing assembly 3. The bottom bracket assembly comprises a bottom bracket 1, a motor assembly 5 arranged on the bottom bracket 1, and a connecting rod mechanism 4 connected to the motor assembly 5 in a transmission manner, an upper bracket connecting plate 6 is arranged on the connecting rod mechanism 4, and a connecting rod upper bracket 7 for mounting the tail wing assembly 3 is arranged on the upper bracket connecting plate 6.

[0070] An adjustment structure and an indication structure are provided between the connecting rod upper bracket 7 and the upper bracket connecting plate 6. The adjustment structure is used to adjust the relative position between the connecting rod upper bracket 7 and the upper bracket connecting plate 6, and the indication structure is used to indicate the position adjustment amount of the connecting rod upper bracket 7 relative to the upper bracket connecting plate 6.

[0071] For the electric tail wing of this embodiment, by providing an adjustment structure and an indication structure between the connecting rod upper bracket 7 and the upper bracket connecting plate 6, and connecting the connecting rod upper bracket 7 to the tail wing plate assembly 3, and the upper bracket connecting plate 6 is arranged on the connecting rod mechanism 4. Thus, during the process of adjusting the tail wing surface difference, the indication structure can indicate the position adjustment amount of the connecting rod upper bracket 7 relative to the upper bracket connecting plate 6, so that the surface difference of the tail wing plate assembly 3 can be quickly adjusted to the set position without the aid of external tools, making the adjustment operation simple and time-consuming short, thereby improving the adjustment efficiency.

[0072] Based on the above overall introduction, an exemplary structure of the electric tail wing of this embodiment is referred to Figures 1 to 7 as shown in. Its overall shape is the same as the existing structure and is a long strip extending along the left-right direction of the whole vehicle. Among them, in combination with Figures 8 to 13 as shown in, as a specific embodiment, the upper bracket connecting plate 6 of this embodiment is generally in a long strip-shaped rod structure, and a lug protruding upward is provided in the middle of its length direction.

[0073] And as a preferred embodiment, as Figure 12 and Figure 13 shown in, the connecting rod upper bracket 7 is in an "L" shape and has a vertical plate and a horizontal plate. Among them, the vertical plate is used to connect to the upper bracket connecting plate 6, and the horizontal plate is used to install the above-mentioned tail wing plate assembly 3. It can be seen that with this structure of the connecting rod upper bracket 7, it not only has good structural strength, but also is convenient to connect to both the tail wing plate assembly 3 and the upper bracket connecting plate 6. And, as a specific implementation manner, fixing holes are provided on the horizontal plate of the connecting rod upper bracket 7, and the tail wing plate assembly can be fixed by bolts. The structure of the tail wing plate assembly can refer to the prior art and will not be elaborated here.

[0074] In addition, as a preferred implementation manner, the connecting rod upper bracket 7 of this embodiment is connected to the upper bracket connecting plate 6 through a connecting component. And the adjustment structure includes adjustment holes 702 provided on at least one of the connecting rod upper bracket 7 and the upper bracket connecting plate 6. The adjustment holes are long strip holes 702, and the connecting component passes through the adjustment holes. Among them, in combination with Figure 8 and Figure 11 shown in, the adjustment holes 702 of this embodiment are specifically provided on the connecting rod upper bracket 7, and the adjustment holes 702 generally extend along the height direction of its vertical plate. And the connecting component specifically includes a bolt provided on the upper bracket connecting plate 6 and a nut connected to the bolt.

[0075] In this embodiment, the adjustment hole 702 is set as a long hole, which has a simple structure, is convenient for design and implementation, and can achieve stepless adjustment. Moreover, by passing the connection component through the adjustment hole 702, the connection component can be arranged to pass through the adjustment hole 702, so that the adjustment hole 702 can serve as part of the connection structure, eliminating the need to additionally provide through holes for bolts to pass through, thus simplifying the features and reducing the processing cost.

[0076] It should be noted here that in addition to arranging the adjustment hole 702 on the connecting rod upper bracket 7, the adjustment hole 702 can also be arranged on the upper bracket connecting plate 6. In this case, the bolt can be arranged on the connecting rod upper bracket 7.

[0077] In addition, as a preferred embodiment, the indicating structure of this embodiment includes a plurality of scale lines 601 arranged on one of the connecting rod upper bracket 7 and the upper bracket connecting plate 6, and an indicating line 701 arranged on the other of the connecting rod upper bracket 7 and the upper bracket connecting plate 6 corresponding to the scale lines 601. Moreover, the plurality of scale lines 601 are arranged in sequence along the length direction of the adjustment hole 702. Here, continue to refer to Figure 8 、 Figure 11 and Figure 13 As shown in, as a specific embodiment, the scale lines 601 of this embodiment are specifically arranged on the upper bracket connecting plate 6 and extend substantially along its width direction. The indicating line 701 is arranged on the vertical plate of the connecting rod upper bracket 7 corresponding to the above adjustment hole 702.

[0078] It can be understood that in addition to arranging the scale lines 601 on the upper bracket connecting plate 6 and arranging the indicating line 701 on the connecting rod upper bracket 7, the scale lines 601 can also be arranged on the connecting rod upper bracket 7 and the indicating line 701 can be arranged on the upper bracket connecting plate 6.

[0079] In addition, to improve the stability of the tail fin plate assembly 3 during movement, generally, link mechanisms 4, connecting rod upper brackets 7 and upper bracket connecting plates 6 are provided on both sides thereof, and are connected to the bottom bracket assembly through the link mechanisms 4. At the same time, the motor assembly 5 is arranged between the two link mechanisms 4 to drive the two link mechanisms 4 to move simultaneously. Therefore, as Figure 15 As shown in, as a preferred embodiment, the bottom bracket 1 of this embodiment extends along the length direction of the tail fin plate assembly 3, with a concave installation groove 101 formed in the middle thereof, and concave installation platforms 102 provided at both ends in the length direction. Among them, the above motor assembly 5 is installed in the installation groove 101, and the two link mechanisms 4 are respectively installed on the installation platforms 102 at the corresponding ends.

[0080] Among them, as Figure 14As shown, in a specific embodiment of the crop, three mounting posts are provided at intervals in the mounting groove 101, and the motor assembly 5 is specifically connected to the mounting posts by screws. It can be understood that the number of mounting posts is not limited to Figure 14 As shown, it can be adjusted accordingly according to requirements. In addition, to facilitate the connection between the transmission shaft 502 of the motor assembly 5 and the link mechanisms 4 at both ends, as Figure 14 As shown, the left and right sides of the mounting groove 101 are respectively provided with hollowed-out settings. In addition, to mount the bottom bracket 1 on the vehicle body, mounting structures are provided at the bottom of the mounting groove 101 and the bottom of the mounting platform 102, and conventional screwing or welding structures can be used, which will not be elaborated here.

[0081] Combined with Figure 14 and Figure 15 As shown, a shaft hole is provided on the bottom bracket 1 on one side of the mounting platform 102, and a bushing is press-fitted in the shaft hole, and the above-mentioned transmission shaft 502 passes through the bushing and is connected to the link mechanism 4. In addition, still referring to Figure 15 As shown, inner supports 104 and outer supports 103 are arranged at intervals on the mounting platform 102, and the inner support 104 is used to mount the following first inner support rod 403, and the outer support 103 is used to mount the following first outer support rod 405. And, to obtain better use effects, as a preferred embodiment, the bottom bracket 1 can be specifically made of cast aluminum. Of course, it is also feasible to use other materials.

[0082] As a preferred implementation method, the link in the link mechanism 4 of this embodiment is directly connected to the bottom bracket 1. Thus, the setting of the traditional base can be omitted, and the overall weight and cost of the electric tail wing can be reduced. Combined with Figures 8 to 13 As shown, as a preferred embodiment, the link mechanism 4 of this embodiment includes a crank 401, a first inner support rod 403, a second inner support rod 404, a driven link 402, and a first outer support rod 405, a second outer support rod 406, and a linkage link. Among them, the crank 401 is connected to the transmission shaft 502 of the motor assembly 5, and the upper support connection plate 6 is connected between the second inner support rod 404 and the second outer support rod 406. And the first inner support rod 403 and the first outer support rod 405 are both connected to the bottom bracket 1 through connectors, and the connectors are connected from the side of the link mechanism 4.

[0083] In addition, as Figure 12 As shown, the second inner support rod 404 is hinged between the upper support connection plate 6 and the other end of the first inner support rod 403, and the driven link 402 is hinged between the crank 401 and the first inner support rod 403. And the second outer support rod 406 is hinged between the upper support connection plate 6 and the other end of the first outer support rod 405, and the linkage link is arranged between the first inner support rod 403 and the second outer support rod 406.

[0084] And, referring to Figure 12 as shown in, the second inner support rod 404 is hinged to the lug of the upper bracket connecting plate 6, while the second outer support rod 406 is hinged to one end of the upper bracket connecting plate 6 in the length direction. The link mechanism 4 of this embodiment adopts the above structure, having the advantages of simple structure, stable transmission, and being able to improve the stability during the movement of the tail fin plate assembly 3. And both the first inner support rod 403 and the first outer support rod 405 are connected to the bottom bracket 1 through connectors, and the connectors are connected from the side of the link mechanism 4. This structure does not require tightening the nut torque after flipping the tail fin up and down like the traditional tail fin assembly. This structure can complete the assembly process from the front, improving the production efficiency during the assembly production of the product, and also eliminating the rotating tooling, saving the equipment investment on the production line. Thus, it is convenient to install the link mechanism 4 and can improve the installation efficiency.

[0085] In addition, as Figure 11 and Figure 12 shown in, when the electric tail fin link mechanism 4 of this embodiment is in the closed state, the crank 401 and the driven link 402 are collinear, which is also the hinge point of the crank 401 and the transmission shaft 502, the hinge point between the crank 401 and the driven link 402, and the hinge point between the driven link 402 and the first inner support rod 403. These three hinge points are on the same straight line, that is, the driving force of the transmission shaft 502 acts on the driven link 402 through the crank 401 and passes through the rotation center of the driven link 402, so that the first inner support rod 403 cannot rotate, reaching a mechanical self-locking state and making the closed state more stable.

[0086] In addition, as Figure 12 shown in, when the electric tail fin of this embodiment is in the open state, the crank 401 and the driven link 402 are in a collinear state, that is, the above three hinge points are on the same straight line, which is the same as the principle of the electric tail fin in the closed state above, and can form a mechanical lock for the electric tail fin in the open state, ensuring the stability of the tail fin.

[0087] Among them, as a preferred embodiment, as Figure 13As shown in the figure, in this embodiment, two hinged connecting rods are riveted together by a pin. One connecting rod is fixedly connected to the pin, and the other connecting rod is rotatably arranged on the pin through a bushing. The bushing has a small-diameter portion inserted into the connecting rod and a large-diameter portion located on one side of the connecting rod. From the perspective of connecting rod production, this structure not only reduces the overall weight of the connecting rod mechanism 4, but also eliminates two steps of riveting in the single connecting rod assembly process, saves a set of riveting tooling, and reduces production costs. In addition, the first inner support rod 403 is connected to the inner support 104 by a stepped screw. A bushing is provided in the hole of the first inner support rod 403 through which the screw passes, and the bushing is sleeved outside the stepped screw to enable rotation relative to the stepped screw. The first outer support rod 405 is also connected to the outer support 103 by a stepped screw, and its structure is generally the same as the installation structure of the first inner support rod 403 and will not be repeated here.

[0088] In addition, as a further implementation, as Figure 12 shown in the figure, a first opening limiting portion is provided between the second inner support rod 404 and the upper support connecting plate 6 to limit the rotation of the second inner support rod 404 when the tail wing is opened. The first opening limiting portion includes a limiting groove 4041 formed by the bending of the second inner support rod 404 itself and a limiting protrusion 602 provided on the upper support connecting plate 6. In this embodiment, by providing the first opening limiting portion, the stability of the tail wing plate assembly 3 in the opened state can be improved. The first opening limiting portion includes the limiting groove 4041 formed by the bending of the second inner support rod 404 itself and the limiting protrusion 602 provided on the upper support connecting plate 6, and its structure is simple and convenient for design and implementation.

[0089] In addition, to improve the stability of the tail wing plate assembly 3 in the closed state, a first closing limiting portion is provided between the first outer support rod 405 and the bottom support 1 to limit the rotation of the first outer support rod 405 when the tail wing is closed. The first closing limiting portion includes a buffer member 105 provided on the bottom support 1. The buffer member 105 can abut against the first outer support rod 405, which can effectively solve the problem of poor stiffness of the connecting rod mechanism 4 due to too long a cantilever when the tail wing is closed. And in combination with Figure 10 and Figure 15 shown in the figure, as a specific embodiment, the buffer member 105 of this embodiment is specifically provided on the mounting table 102 of the bottom support 1 and can be made of rubber.

[0090] As a further implementation, a second closing limiting portion is provided between the first outer support rod 405 and the upper support connecting plate 6 to limit the rotation of the upper support connecting plate 6 when the tail wing is closed. The second closing limiting portion includes a limiting block 4051 provided on one of the first outer support rod 405 and the upper support connecting plate 6 and a first buffer block 408 provided on the other of them. And in combination withFigure 10 , Figure 11 and Figure 13 As shown in Figure 10 , Figure 11 and Figure 13 , the limit block 4051 of this embodiment is specifically provided on the first outer support rod 405 and is formed by bending the first outer support rod 405 itself to one side, while the first buffer block 408 is provided on the upper support connecting plate 6.

[0091] It can be understood that, in addition to setting the limit block 4051 on the first outer support rod 405 and setting the first buffer block 408 on the upper support connecting plate 6, the first buffer block 408 can also be set on the first outer support rod 405, and the limit block 4051 can be set on the upper support connecting plate 6. In addition, in addition to being integrally formed on the first outer support rod 405, the limit block 4051 can also be welded or adhered to the first outer support rod 405. The first buffer block 408 can be specifically provided on the upper support connecting plate 6 by means of plugging, embedding or adhesion, and is preferably plugged on the upper support connecting plate 6 for easy replacement.

[0092] At this time, to improve the setting firmness of the first buffer block 408, as Figure 12 shown in Figure 12 , a cavity is formed inside the first buffer block 408, and openings communicating with the cavity are formed at the top and side. At the same time, upper protrusions and lower protrusions are formed on the upper support connecting plate 6 in a relative arrangement. The first buffer block 408 is inserted on the upper support connecting plate 6 through the openings on the side, and the upper protrusions are inserted into the openings at the top, whereby the first buffer block 408 can be prevented from detaching from the upper support connecting plate 6.

[0093] As a further implementation manner, a third closing limit part is provided between the first outer support rod 405 and the second outer support rod 406 to limit the rotation of the second outer support rod 406 when the tail wing is closed. Among them, the third closing limit part includes a second buffer block 407 provided on either the first outer support rod 405 or the second outer support rod 406, and the second buffer block 407 can abut against the other. In this embodiment, by providing a third closing limit part between the first outer support rod 405 and the second outer support rod 406, the stability of the tail wing plate assembly 3 in the closed state can be further improved, and the overall stiffness can be increased.

[0094] And as a specific embodiment, as Figure 10 and Figure 11As shown in the figure, the second buffer block 407 of this embodiment is specifically arranged on the first outer support rod 405. Among them, the second buffer block 407 can be specifically adhered to the first outer support rod 405, or inserted into the first outer support rod 405 by referring to the method of the above-mentioned first buffer block 408. It should be noted that in addition to arranging the second buffer block 407 on the first outer support rod 405, the second buffer block 407 can also be arranged on the second outer support rod 406. In addition, to prevent abnormal noise, the first buffer block 408 and the second buffer block 407 are preferably made of rubber.

[0095] Here, it should be mentioned that the first closing limit part, the second closing limit part and the third limit part can be set simultaneously, or only one or two of the closing limit parts can be set.

[0096] In addition, as a preferred implementation manner, the controller of the electric tail wing is integrated in the motor assembly 5 of this embodiment, and it can be set with reference to the prior art and will not be elaborated here. Thus, additional control installation can be reduced. Among them, in combination Figure 16 and Figure 17 As shown in the figure, the motor assembly 5 of this embodiment includes a housing 501 with an accommodation cavity, a motor 503 and a PCB board 504 arranged in the housing 501, and a transmission mechanism arranged between the motor 503 and the link mechanisms 4 on both sides.

The housing 501 is screwed to the mounting post through the screw passing through the third buffer block. And the third buffer block is preferably made of rubber to reduce vibration.

[0097] Continue to refer to Figure 17 As shown in the figure, the transmission shaft 502 penetrates through the housing 501 and extends out from both ends of the housing 501 to be connected to the link mechanisms 4 on both sides. And teeth are arranged on both ends of the transmission shaft 502 along its circumferential direction, and internal teeth adapted to the teeth are arranged in the connection holes of the crank 401. When the transmission shaft 502 is inserted into the connection hole of the crank 401, the crank 401 and the transmission shaft 502 can be driven to rotate synchronously through the cooperation of the teeth and the internal teeth. As Figure 17 As shown in the figure, as a preferred embodiment, the transmission mechanism of this embodiment includes two-stage worm and worm gear mechanisms 505, and the worm of the first-stage worm and worm gear mechanism is connected to the output shaft of the motor 503, and the worm gear of the second-stage worm and worm gear mechanism is connected to the transmission shaft 502. Thus, the self-locking function of the worm and worm gear mechanism can be utilized to further improve the stability when the tail wing is opened and closed.

[0098] In addition, as a preferred embodiment, the decorative cover assembly 2 of this embodiment includes a decorative cover 201 covering the upper part of the bottom support 1. A through hole K for the link mechanism 4 to pass through is provided on the decorative cover 201, and a decorative plate cover 202 is provided on the decorative cover 201. Moreover, the decorative plate cover 202 has a shielding portion 2021 located above the decorative cover 201, and the shielding portion 2021 at least forms a shield for the side of the link mechanism 4 facing the outside of the vehicle. Due to the space limitation during the assembly of the electric tail wing, sufficient assembly space needs to be reserved for the installation position of the link mechanism 4. In this embodiment, by adding the decorative plate cover 202, it can effectively avoid a large exposed area of the link mechanism 4 due to assembly space problems. The decorative plate cover 202 can be removed when installing the link mechanism 4 on the bottom support 1, and after the installation is completed, the decorative plate cover 202 can shield at least part of the link mechanism 4, thereby reducing the exposed area of the link mechanism 4 and increasing the aesthetics.

[0099] Among them, as shown in Figures 18 to 21 , the decorative cover 201 generally conforms to the shape of the above-mentioned tail wing plate assembly 3 and also extends along the left-right direction of the whole vehicle. And a connection structure connected to the vehicle body is also provided on the decorative cover 201. Specifically, the connection structure is a buckle 20111 provided on the decorative cover 201. Of course, in addition to using the buckle 20111, it is also possible to use a stud connected to the vehicle body by screwing or a through hole for a bolt to pass through. Additionally, as a specific embodiment, the decorative cover 201 of this embodiment is snap-connected to the above-mentioned bottom support 1 through the buckle 20111. Obviously, in addition to snap-connecting the decorative cover 201 to the above-mentioned bottom support 1 through the buckle 20111, it is also feasible to connect the two by screwing with bolts.

[0100] In addition, to further improve the overall aesthetics, as shown in Figure 21 , the decorative cover 201 includes a body part 2011.

At the same time, the decorative plate cover 202 is inserted and connected to the extension part 2012.

[0101] Among them, as shown in Figure 21 and Figure 22 , as a preferred embodiment, in addition to the above-mentioned shielding portion 2021, the decorative plate cover 202 of this embodiment further includes a top part 2022 provided at the top of the shielding portion 2021 and extending to one side. And after the decorative plate cover 202 is connected to the decorative cover 201, the top part 2022 blocks the through hole K. With such a design, the through hole K can be designed larger, which is more conducive to the installation of the link mechanism 4 on the bottom support 1. Additionally, as shown in Figure 21And Figure 22 As shown in Figure 22 , as a specific embodiment, a buckle 20111 is provided on the body part 2011 of the decorative cover plate 201. Correspondingly, a clamping hole 20221 that is clamped with the buckle 20111 is provided on the top part 2022 of the decorative plate cover 202.

[0102] Meanwhile, an outwardly protruding insertion block 20211 is provided at the edge of the shielding part 2021 of the decorative plate cover 202, and a slot with a downward opening is formed on the extension part 2012 of the decorative cover plate 201. Thus, the top part 2022 of the decorative plate cover 202 can be clamped and connected to the body part 2011 of the decorative cover plate 201 in a direction from bottom to top, and the shielding part 2021 of the decorative plate cover 202 can be inserted and connected to the extension part 2012 of the decorative cover plate 201.

[0103] It should be noted here that in addition to clamping and connecting the decorative plate cover 202 to the body part 2011, at the same time, inserting and connecting the decorative plate cover 202 to the extension part 2012.
