Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a modified rear wing rotation and deployment mechanism. Background Technology

[0002] With the development of the automotive industry and the popularization of car culture, personalized modification of cars has become a trend. Among them, adding a car spoiler is one of the most popular modification projects. A car spoiler can not only enhance the aesthetics of the vehicle and make it look more sporty, but also provide downforce to the vehicle at high speeds, thereby enhancing driving stability.

[0003] Currently, most aftermarket rear wings on the market are fixed in structure. These fixed wings are directly fixed to the rear of the car with bolts or glue, and their shape and angle cannot be changed after installation. Although this design is simple in structure, it has inherent limitations. At high speeds, the rear wing needs a certain angle to generate effective downforce, while at low speeds or when stationary, the high-rising rear wing not only loses its aerodynamic function but also increases wind resistance and affects the overall aesthetics and harmony of the vehicle. This design, which cannot be adjusted according to different driving conditions, makes it impossible to balance aesthetics and practicality.

[0004] To overcome the shortcomings of fixed rear wings, active rear wings with lifting or angle adjustment functions have emerged. However, the deployment mechanism of existing active rear wings has a complex internal transmission structure, which not only increases manufacturing costs but also reduces the reliability of the mechanism. The complex structure also makes the installation process very cumbersome, requiring a lot of modifications to the vehicle body, making it unsuitable for ordinary users to install themselves. In addition, once the mechanism fails, the connection between the rear wing plate and the drive mechanism is permanent or semi-permanent, and it does not have the function of quick disassembly, which brings inconvenience to vehicle cleaning or parts replacement.

[0005] Therefore, this utility model proposes to modify the tail wing rotation and deployment mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of complex structure, inconvenient installation and maintenance, and inability to balance aesthetics and practicality under different driving conditions in the existing technology of modified tail wing rotation and deployment mechanism, this utility model aims to provide a modified tail wing rotation and deployment mechanism with improved structure that can effectively solve the above problems.

[0007] This utility model provides a modified tail wing rotation and deployment mechanism, including: a mounting base, a motor, a rotating disk, a first sliding groove, a first support plate, and a second sliding groove; it also includes a first support rod, a first support block, a rotating shaft, a second support plate, a second support block, a second support rod, and a mounting mechanism.

[0008] The rotational motion of the motor is converted into the rotational deployment of the tail fin through a unique linkage-slider mechanism.

[0009] Furthermore, one end of the first support rod is pivotally connected to the rotating disk, and the other end is slidably accommodated in the second sliding groove on the inner wall of the first support plate. The first support plate is slidably disposed in the first sliding groove on the top of the mounting base. The first support block is fixed to the top of the mounting base, and the rotating shaft is connected to the top of the first support block. The front side of the second support plate is connected to the outer wall of the rotating shaft through another support rod. The second support block is connected to the top of the first support plate, and the rear bottom side of the second support plate abuts against the top of the second support block. The mounting mechanism is used to detachably fix the tail fin to the top of the second support plate.

[0010] Preferably, the first sliding groove is a straight guide rail extending along the sliding direction of the first support plate.

[0011] Preferably, the second sliding groove is an arc-shaped groove.

[0012] Preferably, the second support block is fixed to the top of the first support plate and slidably abuts against the bottom rear side of the second support plate.

[0013] Preferably, the support rod connecting the second support plate and the rotating shaft is a connecting rod, with one end hinged to the outer wall of the rotating shaft and the other end hinged to the front side of the second support plate.

[0014] Preferably, the mounting mechanism includes a protrusion disposed on the top of the second support plate and a mounting block having a groove structure that matches the shape of the protrusion, the mounting block being used to support the tail fin.

[0015] Preferably, the mounting mechanism further includes a pin as a fixing rod, and a fixing groove is a through hole penetrating the side wall of the mounting block. The fixing rod passes through the fixing groove and the protrusion to lock the mounting block.

[0016] Preferably, the installation mechanism further includes a limiting rod and a limiting groove formed on the outer periphery of the fixed rod. The limiting groove is an annular groove or a radial hole, and the limiting rod is a locking pin or cotter pin that cooperates with the limiting groove for locking.

[0017] Preferably, the first support block is provided with a bearing seat, and the rotating shaft is rotatably installed in the bearing seat.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problem that most modified tail wings in the prior art are fixed and cannot automatically adjust their attitude by setting a motor-driven rotating disk and a support rod to drive the first support plate to move linearly in the slide groove, and the second support plate is rotated and unfolded by the lever action of the second support block and the rotating shaft. The tail wing can automatically and smoothly rotate and unfold or retract, taking into account both dynamic aesthetics and aerodynamic practicality.

[0020] 2. This utility model, by setting a protrusion on the second support plate, allows the tail wing to be fitted onto the protrusion by the mounting block, and uses a combination of a fixing rod and a limiting rod for interlocking and locking. This solves the problems of cumbersome installation and fixing process, inconvenience of disassembly and maintenance in the prior art for retrofitting tail wings. The tail wing can be installed or removed quickly and conveniently, greatly improving installation efficiency and convenience of later maintenance. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4This utility model embodiment provides a modified tail wing rotation and deployment mechanism, including a mounting base 1 and a complete transmission and deployment assembly installed in the mounting base 1. The mounting base 1 is used to fix to the vehicle body and support all moving parts. The modified tail wing rotation and deployment mechanism also includes a second support plate 13 for supporting the tail wing plate 203 and realizing rotation and deployment, and a mounting mechanism 2 for conveniently fixing the tail wing plate 203 to the second support plate 13. A first sliding groove 3 is provided on the top of the mounting base 1, and the first support plate 10 is slidably disposed in the first sliding groove 3. A motor 7 is installed on the inner wall of the mounting base 1, and a rotating disk 8 is connected by a fixed connection. Connected to the output end of motor 7, one end of the second support rod 9 is pivotally connected to the rotating disk 8. The inner wall of the first support plate 10 is provided with a second sliding groove 11. The other end of the second support rod 9 is slidably accommodated in the second sliding groove 11. The first support block 4 is fixedly connected to the top of the mounting base 1. The rotating shaft 5 is connected to the top of the first support block 4. The front side of the second support plate 13 is rotatably connected to the outer wall of the rotating shaft 5 through the first support rod 6. The second support block 12 is fixedly connected to the top of the first support plate 10. The bottom rear side of the second support plate 13 abuts against the top of the second support block 12.

[0030] The mounting mechanism 2 includes a protrusion 201, a mounting block 202, a tail fin 203, a fixing groove 204, a fixing rod 205, a limiting groove 206, and a limiting rod 207. The protrusion 201 is integrally formed or fixedly connected to the top of the second support plate 13. The mounting block 202 is used to support the tail fin 203 and is sleeved on the protrusion 201. The fixing rod 205 passes through the fixing groove 204 of the mounting block 202 and the corresponding through hole on the protrusion 201 in sequence. The limiting rod 207 is pluggably installed in the limiting groove 206 of the fixing rod 205, thus forming a complete mechanical structure that can convert the rotational motion of the motor 7 into the rotation and unfolding of the second support plate 13 around the rotating shaft 5.

[0031] Please refer to Figure 1 and Figure 2The output end of the motor 7 is fixedly connected to a rotating disk 8. One end of the second support rod 9 is pivotally connected to the rotating disk 8 at an off-center position via a rotating shaft. The other end of the second support rod 9 is slidably accommodated in a second sliding groove 11 opened in the inner wall of the first support plate 10. When the motor 7 drives the rotating disk 8 to rotate, one end of the second support rod 9, pivotally connected to the rotating disk 8, moves in a circular motion with the rotating disk 8. At the same time, the other end of the second support rod 9 slides in the second sliding groove 11, which can efficiently convert the rotational motion of the rotating disk 8 into a horizontal pushing and pulling force on the first support plate 10. The first sliding groove 3 is a straight guide rail extending along the sliding direction of the first support plate 10 and is opened on the top of the mounting base 1. The first support plate 10 slides with the first sliding groove 3 through its bottom edge, providing precise guidance and limiting for the movement of the first support plate 10, ensuring high stability and anti-deflection capability of the first support plate 10 during movement. The second sliding groove 11 is preferably an arc-shaped groove, the shape of which is adapted to the movement trajectory of the other end of the second support rod 9 during movement, thereby ensuring the smooth movement of the second support rod 9 in the groove and reducing friction and wear.

[0032] The movement of the first support plate 10 is transformed into the rotational unfolding action of the second support plate 13 through a linkage mechanism consisting of the second support block 12, the first support block 4, the rotating shaft 5, and the first support rod 6. The first support block 4 is provided with a bearing seat, and the rotating shaft 5 is rotatably installed in the bearing seat. The first support rod 6 is a connecting rod, with one end connected to the outer wall of the rotating shaft 5 by a hinge, and the other end connected to the front side of the second support plate 13 by a hinge as well. The second support block 12 is fixedly connected to the top of the first support plate 10 and slidably abuts against the bottom rear side of the second support plate 13. In the assembled state, when the first support plate 10 moves horizontally in the first sliding groove 3, the second support block 12 will lift or lower the rear part of the second support plate 13. Since the front part of the second support plate 13 is hinged to the fixed rotating shaft 5 through the first support rod 6, the lifting and lowering movement of the rear part will inevitably cause the entire second support plate 13 to rotate around the rotating shaft 5.

[0033] As a preferred embodiment, in order to ensure the stability and accuracy of the first support plate 10 during movement, the first sliding groove 3 is preferably a straight guide rail extending along the sliding direction of the first support plate 10, which can provide a clear straight movement path and avoid lateral swaying.

[0034] As a preferred embodiment, in order to make the movement of the second support rod 9 within the second sliding groove 11 smoother, the second sliding groove 11 is preferably an arc-shaped groove. The arc-shaped design can better adapt to the trajectory changes of the second support rod 9 under the drive of the rotating disk 8 and reduce motion interference.

[0035] In a preferred embodiment, in order to ensure effective force transmission between the first support plate 10 and the second support plate 13, the second support block 12 is fixedly connected to the top of the first support plate 10 and slidably abuts against the bottom rear side of the second support plate 13. This abutting method allows the second support plate 13 to remain in contact with the second support block 12 when rotating, and realizes force transmission.

[0036] In a preferred embodiment, in order to enable the second support plate 13 to rotate stably around the rotation axis 5, the first support rod 6 is a connecting rod, with one end connected to the outer wall of the rotation axis 5 by a hinge and the other end connected to the front side of the second support plate 13 by a hinge. This double hinge connection ensures the degree of freedom of the second support plate 13 when rotating, while providing sufficient support.

[0037] In a preferred embodiment, in order to ensure quick installation and disassembly between the tail fin 203 and the second support plate 13, the protrusion 201 is located in the middle of the top surface of the second support plate 13, and the mounting block 202 has a groove structure that matches the shape of the protrusion 201, thereby realizing the initial positioning and connection between the tail fin 203 and the second support plate 13.

[0038] In a preferred embodiment, in order to reliably fix the mounting block 202 and the protrusion 201, the fixing groove 204 is a through hole penetrating the side wall of the mounting block 202, and the fixing rod 205 is a pin-shaped rod. The fixing rod 205 locks the mounting block 202 and the protrusion 201 by passing through the fixing groove 204.

[0039] In a preferred embodiment, to prevent the fixing rod 205 from accidentally coming off during use, the limiting groove 206 is an annular groove or radial hole formed on the outer periphery of the fixing rod 205, and the limiting rod 207 is a locking pin or cotter pin that cooperates with the limiting groove 206 for locking. The limiting rod 207 is pluggable and detachable in the limiting groove 206, providing a secondary locking safety for the fixing rod 205.

[0040] In a preferred embodiment, in order to improve the rotational accuracy and stability of the rotating shaft 5, a bearing seat is provided on the first support block 4, and the rotating shaft 5 is rotatably installed in the bearing seat. The bearing seat is usually equipped with a rolling bearing or a sliding bearing to reduce rotational friction and provide reliable support.

[0041] Working principle:

[0042] When the tail fin needs to be deployed, motor 7 starts, driving the rotating disk 8 connected to the output end of motor 7 to rotate. Since one end of the second support rod 9 is pivotally connected to the rotating disk 8, and the other end is slidably accommodated in the second sliding groove 11 of the first support plate 10, the rotational movement of the rotating disk 8 will push the first support plate 10 through the second support rod 9. And because the first support plate 10 is slidably set in the first sliding groove 3 on the top of the mounting base 1, the movement trajectory of the first support plate 10 is limited to linear movement. Therefore, the first support plate 10 will slide backward or forward in the first sliding groove 3. When the first support plate 10 slides, the second support block 12 also moves synchronously, and pushes up or releases the bottom rear side of the second support plate 13. Since the front side of the second support plate 13 is hinged to the fixed rotating shaft 5 through the first support rod 6, the up and down movement of the rear side of the second support plate 13 will cause the entire second support plate 13 to rotate up or down with the rotating shaft 5 as the fulcrum, thereby driving the tail fin 203 to rotate and unfold or retract. The whole process achieves a smooth and reliable automatic unfolding function through a precise mechanical linkage structure.

[0043] When it is necessary to install or remove the tail fin 203, first remove the limiting rod 207, and then pull out the fixing rod 205 from the fixing groove 204. At this time, the locking between the mounting block 202 and the protrusion 201 is released, and the mounting block 202 supporting the tail fin 203 can be easily removed from the protrusion 201 of the second support plate 13. During installation, the operation is reversed. Align the mounting block 202 with the protrusion 201 and insert it, then insert the fixing rod 205 and lock it with the limiting rod 207. This greatly simplifies the installation and maintenance process and improves the practicality and convenience of the product.
