Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and in particular to an electric rear wing. Furthermore, this invention also relates to a method for assembling the electric rear wing, and a vehicle equipped with the electric rear wing. Background Technology

[0002] An electric rear wing is a car spoiler that can deploy automatically. Also known as an electric aerodynamic spoiler, it is a car component that affects the overall airflow of a car at high speeds. According to aerodynamic principles, the rear wing mainly provides a longitudinal downward pressure on the overall airflow of the car, which improves the stability of the car body and enhances its grip during driving, indirectly reducing the car's energy consumption. At the same time, it adds a distinctive feature to the rear of the car, playing a certain role in enhancing the overall aesthetics of the car.

[0003] Existing electric rear wings typically consist of a base and a rear wing connected to the base via a linkage mechanism. The installation position of the rear wing needs precise control to ensure its fit with the vehicle body and its aesthetics. Excessive surface differences in the rear wing's mounting surface can lead to problems such as loosening and abnormal noises. Therefore, after the rear wing is assembled, the surface difference usually needs to be adjusted. However, traditional surface difference adjustment requires the use of tolerance absorbers, which is technically demanding, complex, time-consuming, and inefficient. Summary of the Invention

[0004] In view of this, the present invention aims to provide an electric tail wing to facilitate adjustment of the surface difference of the electric tail wing and shorten the adjustment time.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] An electric tail wing includes a base assembly, a decorative cover assembly, and a tail wing assembly;

[0007] The base assembly includes a base, a motor assembly mounted on the base, and a linkage mechanism that is connected to the motor assembly in a transmission manner. The linkage mechanism is provided with an upper bracket connecting plate, and the upper bracket connecting plate is provided with a linkage upper bracket for mounting the tail wing assembly.

[0008] An adjustment structure and an indicator structure are provided between the upper support of the connecting rod and the connecting plate of the upper support. The adjustment structure is used to adjust the relative position between the upper support of the connecting rod and the connecting plate of the upper support, and the indicator structure is used to indicate the amount of position adjustment of the upper support of the connecting rod relative to the connecting plate of the upper support.

[0009] Furthermore, the upper bracket of the connecting rod is connected to the upper bracket connecting plate via a connecting assembly;

[0010] The adjustment structure includes an adjustment hole provided on at least one of the upper bracket of the connecting rod and the connecting plate of the upper bracket. The adjustment hole is an elongated hole, and the connecting component passes through the adjustment hole.

[0011] Furthermore, the indicating structure includes multiple scale lines provided on one of the upper bracket of the connecting rod and the connecting plate of the upper bracket, and an indicating line provided on the other of the upper bracket of the connecting rod and the connecting plate of the upper bracket, corresponding to the scale lines.

[0012] The multiple scale lines are arranged sequentially along the length of the adjustment hole.

[0013] Furthermore, the connecting rod in the linkage mechanism is directly connected to the base; and / or,

[0014] The controller for the electric tail wing is integrated into the motor assembly.

[0015] Furthermore, the linkage mechanism includes a crank, a first inner support rod, a second inner support rod, a driven link, a first outer support rod, a second outer support rod, and a linkage;

[0016] The crank is connected to the drive shaft of the motor assembly, and the upper bracket connecting plate is connected between the second inner support rod and the second outer support rod;

[0017] Both the first inner support rod and the first outer support rod are connected to the base via connectors, and the connectors are connected from the side of the linkage mechanism.

[0018] Furthermore, the decorative cover assembly includes a decorative cover covering the base, the decorative cover having a through hole for the linkage mechanism to pass through, and a decorative panel cover being provided on the decorative cover;

[0019] The trim cover has a shielding portion located above the trim cover plate, and the shielding portion at least constitutes a shielding of the linkage mechanism facing outwards.

[0020] Furthermore, the decorative cover plate includes a body portion, the through hole is located on the body portion, and the edge of the through hole is provided with an extension portion extending toward the base;

[0021] The trim cover is detachably connected to the decorative cover plate, and the trim cover is snap-fitted to the body portion, and / or the trim cover is plugged into the extension portion.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The electric tail wing of this invention features an adjustment structure and an indicator structure between the upper support of the connecting rod and the upper support connecting plate, connecting the upper support of the connecting rod to the tail wing assembly, and the upper support connecting plate mounted on the connecting rod mechanism. This allows the indicator structure to indicate the positional adjustment of the connecting rod support relative to the upper support connecting plate during tail wing surface adjustment, enabling rapid adjustment of the tail wing assembly surface to the correct position without the need for external tools. This simplifies the adjustment operation, reduces time consumption, and improves adjustment efficiency.

[0024] Furthermore, the adjustment structure includes an adjustment hole on at least one of the upper support of the connecting rod and the connecting plate of the upper support. This adjustment hole is elongated, resulting in a simple structure that is easy to design and implement. The connecting components pass through the adjustment hole, allowing it to function as part of the connection structure, simplifying features and reducing manufacturing costs. The indicator structure includes multiple scale lines on one of the upper support of the connecting rod and the connecting plate of the upper support, as well as corresponding indicator lines on the other of the two plates. This structure is simple and easy to manufacture.

[0025] Secondly, by directly connecting the connecting rods in the linkage mechanism to the base, the traditional base can be eliminated, reducing the overall weight and cost of the electric tail wing. Furthermore, the controller for the electric tail wing is integrated into the motor assembly, saving space. The linkage mechanism includes a crank, a first inner support rod, a second inner support rod, a driven connecting rod, a first outer support rod, a second outer support rod, and a linkage, resulting in a simple structure, smooth transmission, and improved stability during tail wing assembly operation. Connecting both the first inner and first outer support rods to the base via connectors, with the connectors extending from the side of the linkage mechanism, facilitates installation and improves installation efficiency.

[0026] Furthermore, by providing a trim cover on the trim panel, and having a concealing portion located below the trim panel, with the concealing portion at least partially obstructing the outward-facing side of the linkage mechanism, the exposed portion of the linkage mechanism can be reduced, thereby improving the overall aesthetics of the electric rear wing. The trim cover is detachably attached to the trim panel, and the trim cover is snap-fitted to the main body portion, and / or the trim cover is inserted into the extension portion. This allows the trim cover to be removed when installing the linkage mechanism onto the underbody, facilitating the installation of the linkage mechanism onto the underbody.

[0027] In addition, another object of the present invention is to provide a method for assembling an electric tail fin, the method comprising:

[0028] The underbody assembly and the decorative cover assembly are assembled together, and the tail wing assembly is pre-assembled onto the underbody assembly.

[0029] Under the guidance of the indicator structure between the upper bracket connecting plate and the upper bracket of the connecting rod in the base assembly, the position of the rear wing assembly is adjusted by the adjustment structure between the upper bracket connecting plate and the upper bracket of the connecting rod until the position of the rear wing assembly in the vehicle meets the preset surface difference requirement.

[0030] Furthermore, the pre-assembly of the tail wing assembly onto the connecting rod bracket in the underbody assembly includes:

[0031] The tail fin assembly is connected to the upper support of the connecting rod, and then the upper support of the connecting rod is pre-connected to the upper support connecting plate through the connecting assembly;

[0032] Under the guidance of the indicator structure between the upper bracket connecting plate and the upper connecting rod bracket in the base assembly, the position of the tail wing assembly is adjusted by the adjustment structure between the upper bracket connecting plate and the upper connecting rod bracket, including:

[0033] Adjust the position of the connecting component along the length of the adjusting hole according to the scale line corresponding to the indicator line in the indicator structure;

[0034] When the indicator line is aligned with the scale line at the preset position, the connecting assembly is tightened to fix the relative position between the upper bracket of the connecting rod and the upper bracket connecting plate.

[0035] The assembly method of the electric tail wing of the present invention allows the electric tail wing to be adjusted under the guidance of the indicator structure during the surface difference adjustment process, saving the time and tools required for surface difference adjustment.

[0036] Another object of the present invention is to provide a vehicle having an electric tail wing as described above.

[0037] The vehicle described in this invention has all the beneficial effects of the aforementioned electric rear wing, which will not be repeated here. Attached Figure Description

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

[0072] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0073] This embodiment relates to an electric tail wing, which, in its overall structure, includes a base assembly, a decorative cover plate assembly 2, and a tail wing assembly 3. The base assembly includes a base 1, a motor assembly 5 mounted on the base 1, and a linkage mechanism 4 that is driven and connected to the motor assembly 5. The linkage mechanism 4 is provided with an upper bracket connecting plate 6, and the upper bracket connecting plate 6 is provided with a linkage upper bracket 7 for mounting the tail wing assembly 3.

[0074] An adjustment structure and an indicator structure are provided between the upper support 7 of the connecting rod and the upper support connecting plate 6. The adjustment structure is used to adjust the relative position between the upper support 7 of the connecting rod and the upper support connecting plate 6, and the indicator structure is used to indicate the amount of position adjustment of the upper support 7 of the connecting rod relative to the upper support connecting plate 6.

[0075] In this embodiment, the electric tail wing features an adjustment structure and an indicator structure between the upper support 7 and the upper support connecting plate 6, connecting the upper support 7 to the tail wing assembly 3, and the upper support connecting plate 6 mounted on the linkage mechanism 4. This allows the indicator structure to indicate the position adjustment amount of the upper support 7 relative to the upper support connecting plate 6 during tail wing surface adjustment, enabling rapid adjustment of the tail wing assembly 3 without the need for external tools. This simplifies the adjustment operation, reduces time consumption, and improves adjustment efficiency.

[0076] Based on the above overview, an exemplary structure of the electric tail wing in this embodiment is referenced. Figures 1 to 7 As shown, its overall shape is the same as the existing structure, and it is a long strip extending along the left-right direction of the entire vehicle. Among them, combined with... Figures 8 to 13 As shown in the figure, as a specific embodiment, the upper support connecting plate 6 of this embodiment is generally a long strip rod-shaped structure, and has an upward protruding lug in the middle of its length direction.

[0077] As a preferred embodiment, such as Figure 12 and Figure 13 As shown, the upper support 7 of the connecting rod is L-shaped and has a vertical plate and a horizontal plate. The vertical plate is used to connect with the upper support connecting plate 6, while the horizontal plate is used to install the aforementioned tail fin assembly 3. Therefore, this structure of the upper support 7 not only provides good structural strength but also facilitates connection with both the tail fin assembly 3 and the upper support connecting plate 6. Furthermore, as a specific embodiment, the horizontal plate of the upper support 7 has fixing holes, allowing the tail fin assembly to be fixed with bolts. The structure of the tail fin assembly is based on existing technology and will not be described in detail here.

[0078] Furthermore, as a preferred embodiment, the upper support 7 of the connecting rod in this embodiment is connected to the upper support connecting plate 6 via a connecting assembly. The adjustment structure includes an adjustment hole 702 located on at least one of the upper support 7 and the upper support connecting plate 6. The adjustment hole 702 is an elongated hole, and the connecting assembly passes through the adjustment hole. In conjunction with... Figure 8 and Figure 11 As shown, the adjustment hole 702 in this embodiment is specifically provided on the upper bracket 7 of the connecting rod, and the adjustment hole 702 extends approximately along the height direction of its vertical plate. The connecting assembly specifically includes a bolt provided on the connecting plate 6 of the upper bracket, and a nut connected to the bolt.

[0079] In this embodiment, the adjustment hole 702 is designed as an elongated hole, which is simple in structure, easy to design and implement, and can achieve stepless conditions. Moreover, by passing the connecting component through the adjustment hole 702, the connecting component can be made to pass through the adjustment hole 702, thereby allowing the adjustment hole 702 to serve as part of the connecting structure, eliminating the need for additional through holes for bolts, thus simplifying the features and reducing processing costs.

[0080] It should be noted that, in addition to setting the adjustment hole 702 on the upper bracket 7 of the connecting rod, the adjustment hole 702 can also be set on the connecting plate 6 of the upper bracket. In this case, the bolt can be set on the upper bracket 7 of the connecting rod.

[0081] Furthermore, as a preferred embodiment, the indicating structure of this embodiment includes multiple scale lines 601 provided on one of the upper bracket 7 and the upper bracket connecting plate 6, and an indicating line 701 corresponding to the scale lines 601 provided on the other of the upper bracket 7 and the upper bracket connecting plate 6. The multiple scale lines 601 are arranged sequentially along the length direction of the adjusting hole 702. Continuing to refer to... Figure 8 , Figure 11 and Figure 13 As shown in the illustration, in a specific embodiment, the scale line 601 is specifically provided on the upper bracket connecting plate 6 and extends approximately along its width direction. The indicator line 701 is provided on the vertical plate of the connecting rod upper bracket 7, corresponding to the aforementioned adjustment hole 702.

[0082] It is understandable that, in addition to setting the scale line 601 on the upper bracket connecting plate 6 and the indicator line 701 on the upper bracket 7 of the connecting rod, the scale line 601 can also be set on the upper bracket 7 of the connecting rod and the indicator line 701 can be set on the upper bracket connecting plate 6.

[0083] Furthermore, to improve the stability of the tail fin assembly 3 during movement, generally, linkage mechanisms 4, upper linkage brackets 7, and upper bracket connecting plates 6 are provided on both sides of it, and are connected to the base assembly through the linkage mechanisms 4. Simultaneously, a motor assembly 5 is located between the two linkage mechanisms 4 to drive the two linkage mechanisms 4 to move simultaneously. Therefore, as... Figure 15 As shown in the diagram, in a preferred embodiment, the base 1 extends along the length of the tail fin assembly 3, with a recessed mounting groove 101 formed in its middle, and recessed mounting platforms 102 provided at both ends along the length. The aforementioned motor assembly is mounted within the mounting groove 101, while the two linkage mechanisms 4 are respectively mounted on the mounting platforms 102 at their corresponding ends.

[0084] Among them, such as Figure 14 As shown, in one specific embodiment of the crop, three mounting posts are spaced apart within the mounting groove 101, and the motor assembly 5 is specifically connected to the mounting posts via screws. It is understood that the number of mounting posts is not limited to... Figure 14 As shown, it can be adjusted accordingly as needed. Additionally, to facilitate the connection of the drive shaft 502 of the motor assembly 5 to the linkage mechanisms 4 at both ends, as shown... Figure 14 As shown, the mounting groove 101 has openwork on both the left and right sides. In addition, in order to mount the base 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. Conventional screw or welding structures can be used, which will not be described in detail here.

[0085] Combination Figure 14 and Figure 15 As shown, a shaft hole is provided on the base 1 on one side of the mounting platform 102, and a bushing is press-fitted into the shaft hole. The aforementioned drive shaft 502 passes through the bushing and is connected to the linkage mechanism 4. Furthermore, referring to... Figure 15As shown, the mounting platform 102 is provided with an inner support 104 and an outer support 103 arranged at intervals. The inner support 104 is used to install the first inner support rod 403, and the outer support 103 is used to install the first outer support rod 405. Furthermore, in order to obtain better performance, as a preferred embodiment, the base 1 can be made of cast aluminum. Of course, it is also feasible to make it of other materials.

[0086] In a preferred embodiment, the connecting rod in the linkage mechanism 4 is directly connected to the base 1, thereby eliminating the need for a traditional base and reducing the overall weight and cost of the electric tail wing. Combined with... Figures 8 to 13 As shown in the diagram, in a preferred embodiment, the linkage mechanism 4 includes a crank 401, a first inner support rod 403, a second inner support rod 404, a driven connecting rod 402, a first outer support rod 405, a second outer support rod 406, and a linkage. The crank 401 is connected to the drive shaft 502 of the motor assembly 5, and the upper bracket connecting plate 6 is connected between the second inner support rod 404 and the second outer support rod 406. Both the first inner support rod 403 and the first outer support rod 405 are connected to the base support 1 via connectors, which are connected from the side of the linkage mechanism 4.

[0087] In addition, such as Figure 12 As shown, the second inner support rod 404 is hinged between the upper bracket connecting plate 6 and the other end of the first inner support rod 403, while the driven connecting rod 402 is hinged between the crank 401 and the first inner support rod 403. The second outer support rod 406 is hinged between the upper bracket connecting plate 6 and the other end of the first outer support rod 405, and the linkage is located between the first inner support rod 403 and the second outer support rod 406.

[0088] Furthermore, referring to Figure 12 As shown, 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 along its length. The linkage mechanism 4 in this embodiment adopts the above structure, which has the advantages of simple structure, smooth transmission, and improved stability during the operation of the tail fin assembly 3. Both the first inner support rod 403 and the first outer support rod 405 are connected to the base 1 via connectors, which are connected from the side of the linkage mechanism 4. This structure eliminates the need for the traditional tail fin assembly to be flipped up and down before tightening the nut torque; the assembly process can be completed from the front, improving production efficiency during assembly and saving on equipment investment in the production line by eliminating the need for rotating tooling. Therefore, the linkage mechanism 4 can be easily installed, improving installation efficiency.

[0089] In addition, such as Figure 11 and Figure 12As shown, when the electric tail wing linkage 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 between the crank 401 and the drive 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 drive shaft 502 acts on the driven link 402 through the crank 401 and through the rotation center of the driven link 402, so that the first inner support rod 403 cannot rotate, achieving a mechanical self-locking state, making the closed state more stable.

[0090] In addition, such as Figure 12 As shown, in the embodiment, when the electric tail wing is in the open state, the crank 401 and the driven connecting rod 402 are in a collinear state, that is, the three hinge points mentioned above are on the same straight line. This is the same principle as the electric tail wing in the closed state, which can form a mechanical lock on the electric tail wing in the open state to ensure the stability of the tail wing.

[0091] In one preferred embodiment, such as Figure 13 As shown in the illustration, in this embodiment, the two hinged connecting rods are riveted together by a pin. One connecting rod is fixed to the pin, while the other connecting rod is rotatably mounted on the pin via 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 a connecting rod manufacturing perspective, this structure not only reduces the overall weight of the connecting rod mechanism 4 but also eliminates two riveting steps during single-link assembly, saving a set of riveting fixtures and reducing production costs. Furthermore, the first inner support rod 403 is connected to the inner support 104 via a stepped screw. A bushing is provided in the hole through which the screw passes in the first inner support rod 403, and it is fitted over the stepped screw to allow rotation relative to the stepped screw. The first outer support rod 405 is also connected to the outer support 103 via a stepped screw, and its structure is generally the same as the mounting structure of the first inner support rod 403, and will not be repeated here.

[0092] Furthermore, as a further implementation method, such as Figure 12 As shown, a first opening limiting part is provided between the second inner support rod 404 and the upper bracket connecting plate 6 to restrict the rotation of the second inner support rod 404 when the tail fin is opened. The first opening limiting part includes a limiting groove 4041 formed by the bending of the second inner support rod 404 and a limiting protrusion 602 provided on the upper bracket connecting plate 6. In this embodiment, by providing the first opening limiting part, the stability of the tail fin assembly 3 in the opened state can be improved. The first opening limiting part, including the limiting groove 4041 formed by the bending of the second inner support rod 404 and the limiting protrusion 602 provided on the upper bracket connecting plate 6, has a simple structure and is easy to design and implement.

[0093] In addition, to improve the stability of the tail fin assembly 3 in the closed state, a first closing limit part is provided between the first outer support rod 405 and the base 1 to limit the rotation of the first outer support rod 405 when the tail fin is closed. The first closing limit part includes a buffer member 105 provided on the base 1, which can abut against the first outer support rod 405, effectively solving the problem of poor stiffness of the linkage mechanism 4 due to excessive cantilever length when the tail fin is closed. Furthermore, combined with... Figure 10 and Figure 15 As shown in the figure, as a specific embodiment, the buffer 105 of this embodiment is specifically disposed on the mounting platform 102 of the base 1, and may be made of rubber.

[0094] As a further embodiment, a second closing limiting part is provided between the first outer support rod 405 and the upper bracket connecting plate 6 to restrict the rotation of the upper bracket connecting plate 6 when the tail fin is closed. The second closing limiting part includes a limiting block 4051 provided on one of the first outer support rod 405 and the upper bracket connecting plate 6, and a first buffer block 408 provided on the other. Figure 10 , Figure 11 and Figure 13 As shown in the figure, the limiting block 4051 of this embodiment is specifically disposed on the first outer support rod 405 and is formed by bending the first outer support rod 405 to one side, while the first buffer block 408 is disposed on the upper bracket connecting plate 6.

[0095] It is understandable that, besides placing the limiting block 4051 on the first outer support rod 405 and the first buffer block 408 on the upper bracket connecting plate 6, the first buffer block 408 can also be placed on the first outer support rod 405, while the limiting block 4051 is placed on the upper bracket connecting plate 6. Furthermore, the limiting block 4051 can be integrally formed on the first outer support rod 405, or it can be welded or bonded to the first outer support rod 405. The first buffer block 408 can be placed on the upper bracket connecting plate 6 by insertion, embedding, or bonding, and is preferably inserted into the upper bracket connecting plate 6 for easy replacement.

[0096] At this point, to improve the stability of the first buffer block 408, such as Figure 12 As shown, the first buffer block 408 has a cavity inside, and openings communicating with the cavity are formed on the top and sides. At the same time, an upper protrusion and a lower protrusion are formed on the upper support connecting plate 6. The first buffer block 408 is inserted into the upper support connecting plate 6 through the side opening, and the upper protrusion is inserted into the top opening. This prevents the first buffer block 408 from detaching from the upper support connecting plate 6.

[0097] As a further embodiment, a third closing limiting part is provided between the first outer support rod 405 and the second outer support rod 406 to restrict the rotation of the second outer support rod 406 when the tail fin is closed. The third closing limiting part includes a second buffer block 407 disposed on one of the first outer support rod 405 and 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 limiting part between the first outer support rod 405 and the second outer support rod 406, the stability of the tail fin assembly 3 in the closed state can be further improved, and the overall rigidity can be increased.

[0098] As a specific implementation example, Figure 10 and Figure 11 As shown, in this embodiment, the second buffer block 407 is specifically disposed on the first outer support rod 405. Specifically, the second buffer block 407 can be glued to the first outer support rod 405, or inserted into the first outer support rod 405 in the same manner as the first buffer block 408 described above. It should be noted that, in addition to being disposed on the first outer support rod 405, the second buffer block 407 can also be disposed on the second outer support rod 406. Furthermore, to prevent abnormal noise, the first buffer block 408 and the second buffer block 407 are preferably made of rubber.

[0099] It should be mentioned here that the first closing limit part, the second closing limit part and the third limit part can be provided at the same time, or only one or two closing limit parts can be provided.

[0100] Furthermore, as a preferred embodiment, the motor assembly 5 in this embodiment integrates a controller for the electric tail wing, which can be configured according to existing technology and will not be described in detail here. This reduces the need for additional control installation. In conjunction with... Figure 16 and Figure 17 As shown, the motor assembly 5 of this embodiment includes, in terms of mechanical structure, a housing 501 with a receiving cavity, a motor 503 and a PCB board 504 disposed within the housing 501, and a transmission mechanism disposed between the motor 503 and the connecting rod mechanisms 4 on both sides. The housing 501 has mounting holes corresponding to the aforementioned mounting posts, and one side of each mounting hole has a notch. A third buffer block is fitted into the mounting hole, and the housing 501 is screwed to the mounting posts via screws passing through the third buffer block. The third buffer block is preferably made of rubber to reduce vibration.

[0101] Continue to refer to Figure 17As shown, the drive shaft 502 passes through the housing 501 and extends to both ends of the housing 501 to connect with the connecting rod mechanisms 4 on both sides. Furthermore, teeth are provided at both ends of the drive shaft 502 along its circumference, and internal teeth that mate with these teeth are provided in the connecting holes of the crank 401. When the drive shaft 502 is inserted into the connecting holes of the crank 401, the engagement of the teeth and the internal teeth drives the crank 401 and the drive shaft 502 to rotate synchronously. Figure 17 As shown in the diagram, in a preferred embodiment, the transmission mechanism includes a two-stage worm gear mechanism 505. The worm of the first-stage worm gear mechanism is connected to the output shaft of the motor 503, while the worm wheel of the second-stage worm gear mechanism is connected to the transmission shaft 502. Therefore, the self-locking effect of the worm gear mechanism can be utilized to further improve the stability when the tail fin is opened and closed.

[0102] Furthermore, as a preferred embodiment, the decorative cover assembly 2 of this embodiment includes a decorative cover 201 covering the base 1. The decorative cover 201 has a through hole K for the linkage mechanism 4 to pass through, and a trim cover 202 is provided on the decorative cover 201. The trim cover 202 has a shielding portion 2021 located above the decorative cover 201, and the shielding portion 2021 at least shields the linkage mechanism 4 facing outwards. Due to space limitations during the assembly of the electric rear wing, sufficient assembly space needs to be reserved for the installation position of the linkage mechanism 4. In this embodiment, by adding the trim cover 202, the large exposed area of ​​the linkage mechanism 4 due to assembly space issues can be effectively avoided. The trim cover 202 can be removed when installing the linkage mechanism 4 onto the base 1. After installation, the trim cover 202 can shield at least part of the linkage mechanism 4, thereby reducing the exposed area of ​​the linkage mechanism 4 and increasing aesthetics.

[0103] Among them, combined Figures 18 to 21 As shown, the decorative cover 201 generally conforms to the shape of the aforementioned rear spoiler assembly 3, and it also extends along the left-right direction of the vehicle. Furthermore, the decorative cover 201 is also provided with a connection structure for connecting to the vehicle body, specifically a clip 20111 provided on the decorative cover 201. Of course, in addition to using clip 20111, studs bolted to the vehicle body or through holes for bolts to pass through are also possible. In another specific embodiment, the decorative cover 201 in this embodiment is snapped together with the aforementioned base bracket 1 via clip 20111. Obviously, in addition to snapping the decorative cover 201 to the aforementioned base bracket 1 via clip 20111, it is also feasible to connect the two using bolts.

[0104] In addition, to further improve the overall aesthetics, such as Figure 21As shown, the decorative cover plate 201 includes a body portion 2011, a through hole K located on the body portion 2011, and an extension portion 2012 extending toward the base support 1 at the edge of the through hole K. Furthermore, in a preferred embodiment, the decorative cover 202 is detachably connected to the decorative cover plate 201, and the decorative cover 202 is snap-fitted to the body portion 2011, while the decorative cover 202 is inserted into the extension portion 2012.

[0105] Among them, combined Figure 21 and Figure 22 As shown in the diagram, in a preferred embodiment, the trim cover 202 of this embodiment includes, in addition to the aforementioned shielding portion 2021, a top portion 2022 located on top of the shielding portion 2021 and extending to one side. Furthermore, after the trim cover 202 is connected to the decorative cover plate 201, the top portion 2022 blocks the through hole K. This design allows for a larger through hole K, thus facilitating the mounting of the linkage mechanism 4 on the base support 1. Additionally, as... Figure 21 and Figure 22 As shown in the figure, as a specific embodiment, a buckle 20111 is provided on the body portion 2011 of the decorative cover 201, and correspondingly, a snap-fit ​​hole 20221 is provided on the top portion 2022 of the decorative cover 202 to engage with the buckle 20111.

[0106] Meanwhile, a protruding insert 20211 is provided on the edge of the covering portion 2021 of the trim cover 202, and a downward-facing slot is formed on the extension portion 2012 of the decorative cover 201. Thus, the top portion 2022 of the trim cover 202 can be snapped into the body portion 2011 of the decorative cover 201 from bottom to top, and the covering portion 2021 of the trim cover 202 can be inserted into the extension portion 2012 of the decorative cover 201.

[0107] It should be noted that, in addition to snapping the trim cover 202 to the main body 2011, the trim cover 202 is also inserted into the extension 2012. Alternatively, the trim cover 202 may only be snapped to the main body 2011, or the trim cover 202 may only be inserted into the extension 2012.

[0108] The electric tail wing described in this embodiment, by adopting the above structure, not only has a better aesthetic appearance, but also facilitates the adjustment of surface differences and shortens the surface difference adjustment time.

[0109] In addition, this embodiment also relates to an assembly method for an electric tail wing, which generally includes first assembling the base assembly and the decorative cover plate assembly 2 together, and then pre-assembling the tail wing plate assembly 3 on the base assembly.

[0110] Furthermore, under the guidance of the indicator structure between the upper bracket connecting plate 6 and the upper link bracket 7 in the base support assembly, the position of the rear wing assembly 3 is adjusted by the adjustment structure between the upper bracket connecting plate 6 and the upper link bracket 7 until the position of the rear wing assembly 3 in the vehicle meets the preset surface difference requirements.

[0111] Specifically, the tail fin assembly 3 is pre-assembled onto the upper connecting rod bracket 7 in the base assembly, including: connecting the tail fin assembly 3 and the upper connecting rod bracket 7 together, and then pre-connecting the upper connecting rod bracket 7 to the upper bracket connecting plate 6 via a connecting assembly. That is, after connecting the tail fin assembly 3 and the cross plate of the upper connecting rod bracket 7 with bolts, the upper connecting rod bracket 7 and the upper bracket connecting plate 6 are connected by bolts passing through the adjustment hole 702.

[0112] Under the guidance of the indicator structure between the upper bracket connecting plate 6 and the upper connecting rod bracket 7 in the base assembly, the position of the tail wing assembly 3 is adjusted via the adjustment structure between the upper bracket connecting plate 6 and the upper connecting rod bracket 7. This includes adjusting the position of the connecting component along the length direction of the adjustment hole 702 according to the scale line 601 corresponding to the indicator line 701 in the indicator structure. Furthermore, when the indicator line 701 is aligned with the scale line 601 at a preset position, the connecting component is tightened to fix the relative position between the upper connecting rod bracket 7 and the upper bracket connecting plate 6.

[0113] In other words, by adjusting the position of the bolt in the adjustment hole 702 according to the scale line 601 corresponding to the indicator line 701, and when the indicator line 701 is aligned with the preset scale line 601, the bolt and nut can be tightened. At this point, the surface difference adjustment can be completed. This adjustment method allows the electric tail wing to be adjusted according to the corresponding position of the indicator line 701 and the scale line 601 during the surface difference adjustment process, saving the time and tools required for surface difference adjustment.

[0114] In addition, this embodiment also relates to a vehicle equipped with the above-described electric rear wing.

[0115] The vehicle in this embodiment has all the beneficial effects of the aforementioned electric rear wing, which will not be repeated here.

[0116] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
