Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a retractable automotive rear wing support rod. Background Technology

[0002] As automotive performance and user personalization needs continue to improve, active aerodynamic systems are becoming increasingly common in mid-to-high-end models. Among these, retractable rear wings are a typical example. They automatically rise at high speeds to increase downforce and improve handling stability, and retract at low speeds or when stationary to reduce wind resistance and improve overall aesthetics. These rear wings typically operate via electric actuators or lead screw mechanisms, requiring their support rods to possess sufficient rigidity, reliable drive performance, and good environmental adaptability.

[0003] However, existing tail wing systems with a dual-support-point layout generally rely on mechanical linkage shafts or open-loop motor control, making it difficult to guarantee high-precision synchronization of the lifting and lowering processes on both sides. This can easily lead to tail wing tilting, movement stagnation, or even structural damage. On the other hand, the tail wing and support rod are mostly fixed with bolts or integrated designs, requiring specialized tools and taking a long time to disassemble and assemble, thus failing to achieve truly rapid replacement. Furthermore, existing quick-release structures often lack reliable locking feedback and anti-accidental activation mechanisms, posing a risk of loosening under vehicle vibration or high-speed airflow impact. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable car rear wing support rod.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retractable car rear wing support rod, including a rear of the vehicle; a telescopic assembly, consisting of two sets located inside the top of the rear of the vehicle, including a micro motor located inside both sides; and a replacement module located on one side of the top of the rear of the vehicle, including a lower base located on the top of one side of the rear of the vehicle and located on top of the micro motor.

[0006] As a further description of the above technical solution:

[0007] The telescopic assembly includes: a nut seat that moves up and down inside the rear of the vehicle and is connected in the middle to the ball screw of the micro motor output end; an inner rod that moves up and down inside the rear of the vehicle and is fixedly connected at the top to the center of the bottom of the lower base and at the bottom to the top of the nut seat; and an outer rod that is located inside the rear of the vehicle and slides up and down inside the outer rod.

[0008] As a further description of the above technical solution:

[0009] The replacement module includes: an upper base, two sets of which are provided and located on top of the lower base; a tail fin, located on top of the two sets of upper bases; and a locking component, located between the lower base and the upper base.

[0010] As a further description of the above technical solution:

[0011] The locking assembly includes: guide posts, disposed on both sides of the top of the lower base; guide sleeves, disposed on both sides of the bottom of the upper base; a sliding ring, which rotates and slides inside the guide sleeve; push blocks, disposed on both sides of the sliding ring; locking steel balls, disposed inside the guide sleeve and moving horizontally on the inner wall of the guide sleeve; and a compression spring, disposed inside the guide sleeve and whose bottom abuts against the top of the sliding ring.

[0012] As a further description of the above technical solution:

[0013] The guide post is provided with positioning slides at four ends of its outer wall, and positioning grooves are opened on the four sides of the cylindrical groove inside the guide sleeve. The guide post slides in the cylindrical groove of the guide sleeve, and the positioning slides in the positioning groove.

[0014] As a further description of the above technical solution:

[0015] The bottom of the inner ring of the sliding ring is set as an inclined surface and slides in contact with the locking steel ball. The top of the guide post has positioning holes at four ends, and the locking steel ball extends into the positioning hole to lock.

[0016] As a further description of the above technical solution:

[0017] The guide sleeve has a sliding groove for the push block on its top outer wall, and it is L-shaped.

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

[0019] 1. By using dual-side independent drive and closed-loop synchronous control of the vehicle's electronic control unit, the left and right height deviation during the raising and lowering of the tail wing is reduced, ensuring that the tail wing remains horizontal at high speeds, improving aerodynamic stability and structural reliability, and avoiding the risk of jamming and failure caused by traditional mechanical linkage.

[0020] 2. By innovatively adopting an L-shaped groove push block combined with a sloping sliding ring and locking steel ball quick-release mechanism, the rear wing can be replaced without tools in just two steps: pushing up and rotating. It also features anti-accidental touch, vibration resistance and high positioning accuracy, meeting users' personalized modification needs and vehicle safety requirements.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment provides a retractable car rear wing support rod, including: a rear end 1; a telescopic component 2, which is provided in two sets and located inside the top of the rear end 1, including a micro motor 21, which is provided inside both sides; and a replacement module 3, which is provided on one side of the top of the rear end 1, including a lower base 31, which is provided on the top of one side of the rear end 1 and located on top of the micro motor 21.

[0033] In this embodiment, the telescopic component 2 and the replacement module 3 constitute a telescopic automotive rear wing support rod according to this application.

[0034] It should also be noted that the automobile in this application can be a gasoline-powered vehicle, a pure electric vehicle, a smart electric sports sedan, etc. Figure 1 In this embodiment, a gasoline-powered vehicle is used as an example for description. Of course, other types of vehicles can also adopt a similar structure, which will not be elaborated on later.

[0035] It should also be understood that the micro motor 21, vehicle electronic control unit, position sensor and encoder were all purchased from the market and are common knowledge in the field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] In this embodiment, the rear of the vehicle 1 serves as the rear-end support structure, with a pre-reserved installation chamber at the top to accommodate two sets of telescopic components 2. The telescopic components 2 are symmetrically distributed on both sides of the chamber, with a micro motor 21 as the power core, working in conjunction with a lead screw, inner rod 23, and outer rod 24 to achieve telescopic functionality. The replacement module 3 is installed on one side of the top of the rear of the vehicle 1, using the lower base 31 as the connection base, and the upper base 32 to support the rear wing 33. The locking component 34 enables quick installation and removal of the rear wing 33. The overall structure is reasonably laid out, balancing telescopic drive and convenient replacement requirements. Using the rear of the vehicle 1 as the installation carrier, the telescopic components 2 drive the lead screw to rotate via the micro motor 21, causing the nut seat 22 to move up and down, thereby driving the inner rod 23 to slide within the outer rod 24 to achieve telescopic movement, thus raising and lowering the replacement module 3 and the rear wing 33. The replacement module 3 uses the mechanical structure of the locking component 34 to quickly lock and unlock the upper base 32 and the lower base 31, completing the replacement of the rear wing 33. The electronic control unit synchronously controls the two sets of telescopic components 2 to ensure that the rear wing 33 remains horizontal during the raising and lowering process. The symmetrically distributed telescopic components 2 ensure that the tail wing 33 is subjected to balanced force and rises and falls smoothly; the quick-change module 3 greatly shortens the replacement time of the tail wing 33 and improves the flexibility of use; the synchronous control of the electronic control unit ensures the horizontal accuracy of the tail wing 33, avoids tilting and deformation during the raising and lowering process, and ensures driving stability.

[0037] Example 2:

[0038] Based on Embodiment 1, in order to provide the function of a retractable tail wing, a retractable component 2 is installed inside the top of the rear of the vehicle 1.

[0039] Specifically, the telescopic component 2 includes: a nut seat 22, which moves up and down inside the rear of the vehicle 1 and is connected in the middle to the lead screw ball of the output end of the micro motor 21; an inner rod 23, which moves up and down inside the rear of the vehicle 1 and is fixedly connected at the bottom center of the lower base 31 at the top and at the bottom to the top of the nut seat 22; and an outer rod 24, which is located inside the rear of the vehicle 1 and the inner rod 23 slides up and down inside the outer rod 24.

[0040] In this embodiment, the micro motor 21 of the telescopic component 2 is a DC geared motor with a built-in encoder and position sensor for precise control of speed and stroke. The nut seat 22 is a rectangular block structure with a threaded hole in the middle that precisely matches the ball screw at the output end of the micro motor 21. The outer wall has a guide slider that matches the guide groove inside the rear of the vehicle 1. The inner rod 23 is a cylindrical alloy steel part with anti-corrosion treatment. Its bottom is rigidly connected to the nut seat 22 by bolts, and its top is welded to the lower base 31. The outer rod 24 is a hollow cylindrical structure with a smooth inner wall to ensure smooth sliding. The electronic control unit sends synchronization commands to the two sets of micro motors 21. The micro motors 21 drive the ball screw to rotate, and the nut seat 22 moves up and down along the guide groove under the action of the screw thread, causing the inner rod 23 to slide linearly within the outer rod 24. The position sensor provides real-time feedback on the lifting position of the inner rod 23, the encoder monitors the motor speed, and the electronic control unit dynamically adjusts the motor parameters according to the feedback signal to ensure that the two sets of inner rods 23 lift synchronously. The DC geared motor provides stable power output, and the reduction structure increases torque to meet the power requirements for raising and lowering the rear wing 33. The precision ball screw and guide structure ensure accurate movement of the nut seat 22 and smooth sliding of the inner rod 23 without deviation. The corrosion-resistant inner rod 23 extends its service life and is suitable for outdoor use in automobiles. The synchronous control mechanism ensures that the rear wing 33 can be raised and lowered horizontally, avoiding structural damage caused by asynchronous raising and lowering on both sides.

[0041] Example 3:

[0042] Based on Embodiment 2, in order to provide the function of replacing the rear wing, a replacement module 3 is provided on one side of the top of the rear of the vehicle 1.

[0043] Specifically, the replacement module 3 includes: an upper base 32, two sets of which are provided and located on top of the lower base 31; a tail wing 33, located on top of the two sets of upper bases 32; and a locking component 34, located between the lower base 31 and the upper base 32.

[0044] In a preferred embodiment, the lower base 31 of the replacement module 3 is a rectangular steel plate, horizontally fixed to the top of the two sets of inner rods 23, with mounting holes on its surface for mounting the locking assembly 34; the upper base 32 consists of two sets of rectangular metal blocks, symmetrically fixed to the bottom of the rear wing 33, precisely corresponding to the installation position of the lower base 31; the rear wing 33 is made of lightweight carbon fiber material, reducing overall weight and improving vehicle fuel economy; the locking assembly 34 is symmetrically distributed between the lower base 31 and the upper base 32 to ensure a firm connection. When installing the rear wing 33, align the guide sleeve 342 at the bottom of the upper base 32 with the guide post 341 at the top of the lower base 31, press the rear wing 33 down to insert the guide post 341 into the guide sleeve 342, and the upper and lower bases are fixed by the steel ball locking structure of the locking assembly 34; when replacing the rear wing 33, operate the locking assembly 34 to unlock, and pull the rear wing 33 upwards to complete the disassembly. The lightweight carbon fiber rear wing 33 reduces the vehicle's load while possessing high strength characteristics to ensure driving safety; the symmetrically distributed locking components 34 ensure even force distribution and secure locking between the upper and lower bases; the precisely matched installation structure makes the rear wing 33 easy to install and accurately positioned, avoiding installation misalignment that could affect aerodynamic performance.

[0045] Specifically, the locking assembly 34 includes: guide posts 341, disposed on both sides of the top of the lower base 31; guide sleeves 342, disposed on both sides of the bottom of the upper base 32; a sliding ring 343, which rotates and slides inside the guide sleeve 342; push blocks 344, disposed on both sides of the sliding ring 343; locking steel balls 345, disposed inside the guide sleeve 342 and moving horizontally on the inner wall of the guide sleeve 342; and a compression spring 346, disposed inside the guide sleeve 342 and whose bottom abuts against the top of the sliding ring 343.

[0046] In this embodiment, the guide post 341 of the locking assembly 34 is a cylindrical metal part with a chamfered top for easy insertion into the guide sleeve 342; the guide sleeve 342 is a hollow cylindrical structure, welded and fixed to the bottom of the upper base 32, with a steel ball mounting hole on its inner wall; the sliding ring 343 is an annular structure, with its inner wall adapted to the guide sleeve 342, and can rotate and slide up and down; the push block 344 is an arc-shaped block, integrally formed with the sliding ring 343, protruding from the outer wall of the guide sleeve 342, and the end of the push block 344 connected to the sliding ring 343 slides in the L-shaped groove on the outer wall of the guide sleeve 342; the locking steel ball 345 is made of high-hardness stainless steel, with a diameter adapted to the steel ball mounting hole; the compression spring 346 is a cylindrical helical spring, which pushes the sliding ring 343 to a low position in its natural state. In the locked state, the compression spring 346 pushes the sliding ring 343 downwards, and the inclined surface of the inner ring of the sliding ring 343 presses against the locking steel ball 345, causing part of the locking steel ball 345 to extend out of the steel ball mounting hole and embed into the positioning hole of the guide post 341, thus locking the upper and lower bases. When unlocking, pushing the push block 344 upwards causes the sliding ring 343 to press against the compression spring 346 upwards. Rotating the push block 344 causes it to engage with the horizontal section of the L-shaped groove, disengaging the inclined surface of the sliding ring 343 from the locking steel ball 345. The locking steel ball 345 can then slide into the guide sleeve 342, releasing the lock. The high-hardness locking steel ball 345 has good wear resistance, reliable locking, and is not easily deformed. The compression spring 346 provides a stable locking force, ensuring that the locking assembly 34 will not accidentally unlock during driving. The L-shaped groove structure positions the push block 344 in the unlocked position, facilitating the removal and placement of the tail wing 33, and is easy to operate without the need for additional tools.

[0047] Specifically, the guide post 341 has positioning slides at its four ends on its outer wall, and the guide sleeve 342 has positioning grooves on its four sides in the cylindrical groove inside. The guide post 341 slides in the cylindrical groove of the guide sleeve 342, and the positioning slides in the positioning groove.

[0048] With this configuration, the four sets of positioning slides on the outer wall of the guide post 341 are rectangular protrusions, integrally formed with the guide post 341, and distributed along the axial direction of the guide post 341. The positioning groove inside the guide sleeve 342 precisely matches the positioning slides. The lengths of both the positioning slides and the positioning grooves are adapted to the insertion depth of the guide post 341, ensuring that the positioning slides remain within the positioning grooves after the guide post 341 is inserted into the correct position. When installing the tail wing 33, during the insertion of the guide post 341 into the guide sleeve 342, the positioning slides are embedded in the positioning grooves, restricting the relative rotation between the guide post 341 and the guide sleeve 342, ensuring that the positioning hole at the top of the guide post 341 can be precisely aligned with the locking ball 345. At the same time, the cooperation between the positioning slides and the positioning grooves provides guidance for the installation of the upper and lower bases, ensuring accurate installation positioning. The precise fit between the positioning slide and the positioning groove prevents the guide post 341 from rotating and shifting during installation, ensuring that the locking ball 345 can be smoothly embedded in the positioning hole, thus improving locking reliability; the guiding effect makes the tail fin 33 easier to install, eliminating the need for repeated position adjustments and improving replacement efficiency.

[0049] In actual use, the user first pushes the push block 344 upwards, which causes the sliding ring 343 to compress the spring 346 upwards. Then, the user rotates the push block 344, which causes the sliding ring 343 to rotate. The push block 344 is then locked in the horizontal groove of the L-shaped groove on the outer wall of the guide sleeve 342. At this time, the inner ring at the bottom of the sliding ring 343 opens upwards to lock the sliding channel of the locking ball 345. The user locks the four sets of sliding rings 343 at the bottom of the tail fin 33 upwards in sequence. Then, the user pulls the tail fin 33 upwards. One end of the locking ball 345 is pressed by the guide post 341, and the locking ball 345 slides into the guide sleeve 342 to release the lock. Then, the user can replace different tail fins 33. When the user presses the button to raise the tail wing 33, the two sets of micro motors 21 are synchronously driven by the same vehicle electronic control unit (not shown in the figure). The two sets of micro motors 21 have built-in position sensors (not shown in the figure). The electronic control unit dynamically adjusts the speed of the two sets of micro motors 21 according to the real-time feedback signal. The vehicle electronic control unit sends the same forward rotation command to the two sets of micro motors 21 at the same time. The two sets of micro motors 21 rotate synchronously, driving their respective lead screws. The two sets of nut seats 22 rise synchronously. The two sets of inner rods 23 push the lower base 31 to rise synchronously. The electronic control unit reads the encoder data (not shown in the figure) of the two sets of micro motors 21 in real time. The system dynamically adjusts to keep the tail wing 33 horizontal. When the target height is reached, both sides stop at the same time. The tail wing 33 remains in a horizontally deployed state. The same principle applies when retracting, and the operation is performed synchronously in the reverse direction.

[0050] The micro motor 21 inside the rear of the vehicle is equipped with a position sensor; the sensor is electrically connected to the vehicle electronic control unit. The vehicle electronic control unit, as the central hub of the entire system, is responsible for receiving instructions, monitoring the status, and controlling the actions of each actuator. Through preset programs or real-time parameter adjustments, the automated control of the two sets of micro motors 21 can be realized. The position sensor monitors the two sets of micro motors 21 in real time and transmits the sensed signals to the vehicle electronic control unit, which then controls the operation of the two sets of micro motors 21.

[0051] It should be noted that the vehicle electronic control unit can be a conventional known device that is controlled by a computer or the like. The specific embodiments disclosed herein omit detailed descriptions of known functions and known components. To ensure device compatibility, the operating methods used are consistent with the parameters of commercially available devices.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
