Description

Technical Field

[0001] The present application relates to the technical field of automobile rear wing accessories, and in particular to an automatic rear wing strut motor assembly. Background Art

[0002] A car spoiler is an auxiliary device installed at the rear of a car that can change the direction and speed of the airflow, thereby improving the aerodynamic performance of the vehicle while driving, in order to enhance the vehicle's performance and fuel economy.

[0003] There are two types of car spoilers: fixed and foldable. Foldable spoilers are commonly used on civilian cars. Foldable spoilers can be folded according to actual needs, and are more widely applicable. However, there is a gap between the supporting structure of the folded spoiler and the car body, which often causes dirt to accumulate at the installation part of the spoiler. The setting of the supporting mechanism itself makes it difficult to clean this part. Overall, it not only affects the aesthetics of the car, but also affects the stability of the strut assembly.

[0004] To solve the above problems, a Chinese patent with publication number CN217294711U discloses an automated tail wing strut motor assembly. The solution adds a sealing cover, which together encloses the sealing cover, the tail wing mounting plate and the base plate to form an enclosed space for accommodating the support structure, so as to prevent rainwater and dust from entering the installation space of the strut assembly and affecting the working stability of the strut assembly.

[0005] The support structure is driven by a motor and automatically adjusts the tail precisely. It may wear, loosen or malfunction due to the use environment, frequent operation or the passage of time, so it needs regular maintenance. Since the sealing cover is an annular cover that is sealed and fixed between the tail mounting plate and the base plate, it is necessary to remove the fixings of the edges of the sealing cover before maintenance, and then expand the sealing cover to separate its upper and lower ends from the tail mounting plate and the base plate respectively. At this time, the support structure may be forcibly moved. In addition, after the maintenance is completed, the sealing cover needs to be reinstalled according to the same steps, which is overall troublesome and there is still room for optimization. Utility Model Content

[0006] In order to improve the maintenance convenience of the support structure at the tail wing, the present application provides an automatic tail wing strut motor assembly.

[0007] The present application provides an automatic tail wing support rod motor assembly adopts the following technical solution:

[0008] An automatic tail wing strut motor assembly comprises a tail wing mounting plate, a base plate, a linkage support device, and an elastic sealing cover which is sealed between the tail wing mounting plate and the base plate and surrounds the linkage support device;

[0009] The linkage support device comprises a swing arm and a telescopic driving rod respectively rotatably connected to the two ends of the base plate, the plate surface of the base plate is provided with a clearance groove for the telescopic driving rod to move, one end of the swing arm away from the base plate is rotatably connected to the end of the tail wing mounting plate close to the swing arm, the end of the tail wing mounting plate away from the swing arm is connected to a connecting rod, and the other end of the telescopic driving rod is movably connected to the connecting rod;

[0010] The elastic sealing cover is formed in a sheet-like shape, and a slot for inserting the base plate is provided in the middle of the elastic sealing cover. A fixing strip is extended from the open end on one side of the elastic sealing cover, and a plug hole is provided at the open end on the other side. The movable end of the fixing strip is arranged around the plug hole and is detachably connected to the outer side surface of the elastic sealing cover.

[0011] By adopting the above technical solution, after installing other mechanical structures, an elastic sealing cover is arranged around the linkage support device, and the fixing strip is passed around the insertion hole and fixed. At this time, the edge of the elastic sealing cover without the fixing strip is directly fixed by gluing, so that the sheet is formed into a cover body; when disassembly is required, it is only necessary to separate the end of the fixing strip from the insertion hole, and remove the glue using the unglued edge as the entry point to remove the elastic sealing cover. This method is not easy to damage the linkage support device and also improves the convenience of disassembly.

[0012] Optionally, a plate surface of the base plate is provided with a positioning groove for embedding the edge of the elastic sealing cover.

[0013] By adopting the above technical solution, each time the elastic sealing cover is installed, the positioning groove is used to determine the required bonding position to ensure the consistency of the installation position of the elastic sealing cover each time, so as to ensure that the elastic sealing cover does not interfere with the movement trajectory of the linkage support device.

[0014] Optionally, the elastic sealing cover is provided with fixing strips at both upper and lower ends of the slot, and the insertion holes correspond to the fixing strips one by one.

[0015] By adopting the above technical solution, the elastic sealing cover is divided into two parts, the upper part and the lower part, with the slot as the boundary. Both parts are provided with fixing strips and plug holes, so as to be easily disassembled.

[0016] Optionally, the fixing strip includes a strip portion and a head portion connected to each other, the strip portion is connected to the elastic sealing cover, the head portion is inserted with the insertion hole, and the hole diameter of the insertion hole is smaller than the diameter of the head portion.

[0017] By adopting the above technical solution, the size difference between the socket and the head is used for preliminary insurance, thereby reducing the probability of the head being separated from the socket when the vehicle is running.

[0018] Optionally, the head is provided with a guiding slope for facilitating insertion into the socket.

[0019] Optionally, the elastic sealing cover is provided with grooves transversely on both upper and lower sides of the insertion hole, and the grooves penetrate the edges of the elastic sealing cover near the slot.

[0020] By adopting the above technical solution, the opening of the groove makes the sheet at the insertion hole independent from the elastic sealing cover body, so that the matching relationship of the sheet at the insertion hole does not cause stacking at the upper and lower adjacent edges, thereby ensuring the bonding effect and overall aesthetics.

[0021] Optionally, a positioning hole is opened on the plate surface of the base plate, and the positioning hole is located outside the elastic sealing cover.

[0022] By adopting the above technical solution, the position of the positioning hole is limited so that the placement of the sealing cover does not affect the insertion of the positioning hole.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The elastic sealing cover is provided in sheet form, and the elastic sealing cover can be surrounded by a fixing strip, and the fixing strip is passed around the insertion hole and fixed. At this time, the edge of the elastic sealing cover where no fixing strip is provided is directly fixed by gluing, so that the sheet is formed into a cover body. When disassembly is required, only the end of the fixing strip needs to be separated from the insertion hole, and the glue is removed by using the unglued edge as the entry point to remove the elastic sealing cover. This method is not easy to damage the linkage support device, and also improves the convenience of disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] A coordinate system XYZ is set in this article, wherein the positive direction of the Z axis represents the top, the negative direction of the Z axis represents the bottom, the positive direction of the Y axis represents the front, the negative direction of the Y axis represents the back, the positive direction of the X axis represents the right, and the negative direction of the X axis represents the left.

[0031] The present application embodiment discloses an automatic tail wing support rod motor assembly. Figure 1 and Figure 2 The automatic tail wing strut motor assembly includes a tail wing mounting plate 1, a base plate 2, a linkage support device 3, and an elastic sealing cover 4 surrounding the linkage support device 3. The elastic sealing cover 4 is sealed and connected between the tail wing mounting plate 1 and the base plate 2 to protect the linkage support device 3 and prevent rain and dust from entering the linkage support device 3 of the assembly. The plate surfaces of the base plate 2 and the tail wing mounting plate 1 are both provided with positioning grooves 21 for the edges of the elastic sealing cover 4 to be embedded.

[0032] The linkage support device 3 comprises a swing arm 31, a telescopic driving rod 32 and a connecting rod 33. The tail wing mounting plate 1 and the base plate 2 are movably connected through the linkage support device 3 to form a linkage mechanism capable of adjusting the angle.

[0033] In the embodiment of the present application, the base plate 2 is an L-shaped plate, including a horizontal plate 22 and a vertical plate 23 bent and formed on the upper left end of the horizontal plate 22. First hinge frames 231 are welded on both the front and rear sides of the middle of the vertical plate 23, and a first rotation opening 232 is formed between adjacent first hinge frames 231; a clearance groove 221 is penetrated through the right side plate surface of the horizontal plate 22, and second hinge frames 222 are welded on both the front and rear sides of the clearance groove 221 of the horizontal plate 22, and a second rotation opening 223 is formed between adjacent second hinge frames 222, and the center lines of the first rotation opening 232, the second rotation opening 223 and the clearance groove 221 are coaxial.

[0034] The lower end of the swing arm 31 is provided with a first rotation opening 232, and is hinged to the first hinge frame 231 via a rotating shaft. Two first hinge frames 231 are also welded to the lower end of the left side of the tail wing mounting plate 1, so that the upper end of the swing arm 31 is also hinged to the tail wing mounting plate 1. Overall, the movement of the tail wing mounting plate 1 relative to the base plate 2 is limited within a certain angle range.

[0035] The cylinder of the telescopic drive rod 32 is inserted into the clearance groove 221, and a rotating column 321 is integrally formed on both the front and rear sides of the cylinder. The second hinge frame 222 is inserted using the rotating column 321 to achieve a rotational connection with the base plate 2. The right side of the clearance groove 221 is penetrated to avoid interference with the rotation of the telescopic drive rod 32. A motor 322 is installed on the outside of the cylinder of the telescopic drive rod 32, and the motor 322 drives the telescopic drive rod 32 to perform high-precision position control. The cooperation principle and use principle of the motor 322 and the telescopic drive rod 32 are consistent with the existing cooperation, and will not be repeated here.

[0036] A rotating ball seat 11 is welded to the lower end of the right side of the tail wing mounting plate 1. A spherical inner cavity 111 is provided inside the rotating ball seat 11. A strip-shaped rotating notch 112 is provided on one side of the rotating ball seat 11. The rotating notch 112 is connected to the spherical inner cavity 111. A rotating ball seat 11 is also welded to the upper end of the telescopic driving rod 32. Spherical protrusions 331 are formed at both the upper and lower ends of the connecting rod 33. The spherical protrusions 331 are movably inserted into the rotating ball seat 11 to form a ball pair. When the telescopic driving rod 32 rotates adaptively with the rotation of the swing arm 31, the connecting rod 33 can rotate along the rotating notch 112 without interference.

[0037] For connection, positioning holes 24 are opened on the plate surfaces of the base plate 2 and the tail wing mounting plate 1 . The positioning holes 24 on the base plate 2 are located outside the elastic sealing cover 4 , and the positioning holes 24 on the tail wing mounting plate 1 are located inside the elastic sealing cover 4 .

[0038] Reference Figure 1 and Figure 3 The elastic sealing cover 4 is formed by a sheet-shaped enclosure, and in the embodiment of the present application, a rubber material is used as an example. A slot 41 for inserting the base plate 2 is provided in the middle of the left side of the elastic sealing cover 4 to divide the elastic sealing cover 4 into two parts, the lower end of the elastic sealing cover 4 is closed.

[0039] A fixing strip 42 is formed on the left side of the opening of the elastic sealing cover 4. The fixing strip 42 is made of the same material as the elastic sealing cover 4 and is disposed on both the upper and lower sides of the slot 41. A plug hole 43 is provided on the right side of the opening of the elastic sealing cover 4 for the movable end of the fixing strip 42 to be inserted. The plug hole 43 corresponds to the fixing strip 42 one by one.

[0040] The fixing strip 42 includes an integrally formed strip portion 421 and a head portion 422, and the strip portion 421 is integrally formed with the elastic sealing cover 4. The diameter of the head portion 422 is larger than the aperture of the insertion hole 43, but because the head portion 422 has the ability to deform, the head portion 422 can pass through the insertion hole 43 after being squeezed. In order to facilitate the insertion of the insertion hole 43, the head portion 422 is provided with a guiding inclined surface 423. After the head portion 422 and a part of the strip portion 421 are inserted into the insertion hole 43, they are wound around and buckled with the buckle seat bonded to the outside of the elastic sealing cover 4, thereby being fixed on the outer side of the elastic sealing cover 4.

[0041] In addition, a slot 44 is transversely provided at the right edge of the elastic sealing cover 4 and at both the upper and lower sides of the insertion hole 43. The slot 44 is relatively short. The opening of the slot 44 makes the sheet at the insertion hole 43 independent of the elastic sealing cover 4 body, so that the matching relationship of the sheet at the insertion hole 43 does not cause the upper and lower adjacent edges to overlap, thereby ensuring the gluing effect and overall aesthetics.

[0042] The implementation principle of an automatic tail wing strut motor assembly of the embodiment of the present application is as follows: after the linkage support device 3 is installed and fixed, the elastic sealing cover 4 is arranged around the linkage support device 3, so that the base plate 2 is inserted into the slot 41, and the upper and lower edges of the elastic sealing cover 4 are correspondingly inserted into the positioning groove 21 and fixed by gluing. Then, the two fixing strips 42 are both passed around the insertion hole 43 and fastened, and then the edge of the elastic sealing cover 4 without the fixing strip 42 is directly fixed by gluing, so that the sheet is formed into a cover body, and the inside of the cover body is closed into a closed space.

[0043] When the vehicle is started, the on-board computer controls the motor 322 to drive the vehicle tail wing to a retracted state or an extended state. When the tail wing mounting plate 1 reaches the tilting height, the telescopic drive rod 32 is locked by the motor 322, and the whole process is automated and protected by the elastic sealing cover 4.

[0044] When disassembly is required, the end of the fixing strip 42 only needs to be separated from the insertion hole 43, and the glue is removed by taking the un-glued edge as the entry point, and the elastic sealing cover 4 can be removed for maintenance. After the maintenance is completed, a new elastic sealing cover 4 can be reinstalled according to the same steps as above.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
