Description

Technical Field

[0001] This utility model relates to the field of automotive aerodynamic devices, specifically an adaptive automotive aerodynamic device. Background Technology

[0002] With the development of the automotive industry, the optimization of automotive aerodynamic performance has received increasing attention, especially the increasing demand for vehicle stability and drag control at high speeds. Spoilers (such as rear wings) are important components for improving automotive aerodynamic performance. They can increase downforce or reduce drag by adjusting airflow distribution, thereby improving vehicle handling and fuel economy.

[0003] Traditional automotive spoilers are mostly fixed structures, and their height and angle cannot be dynamically adjusted according to actual driving conditions. For example, a fixed rear wing may reduce energy efficiency due to unnecessary wind resistance at low speeds, while it may affect stability due to insufficient downforce when cornering at high speeds. Although some existing technologies have proposed adjustable spoilers, their adjustment methods are usually relatively simple. For example, they only support manual or mechanical height adjustment, or can only make limited adjustments to the overall angle of the rear wing. It is difficult to meet the dynamic needs under complex driving conditions (such as high-speed straight-line acceleration, cornering, and strong crosswinds). In addition, existing adjustable rear wings mostly rely on complex pneumatic or hydraulic systems, which have problems such as bulky structure, slow response speed, and high maintenance costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a car aerodynamic device that can be automatically adjusted to adapt to different driving conditions.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objective is: an adaptive car spoiler device, including a mounting base, a height adjustment mechanism, a lifting sleeve, and a rear wing mechanism. The mounting base is provided in two sets, and a set of lifting sleeves is slidably connected to each set of mounting bases. The height adjustment mechanism is provided inside each set of mounting bases. The height adjustment mechanism includes a moving platform. The moving platform and the lifting sleeve are fixedly connected by a connecting arm. The rear wing mechanism is provided between the two sets of lifting sleeves.

[0006] The tail wing mechanism includes a tail wing plate, a tail wing adjustment mechanism, and a tail wing frame. The tail wing frame is fixedly connected between the two sets of lifting sleeves. The tail wing frame is provided with an airflow port. Multiple sets of tail wing plates are rotatably connected inside the airflow port. The tail wing adjustment mechanism is provided at one end of the tail wing frame. The tail wing adjustment mechanism cooperates with the multiple sets of tail wing plates. The rotation of the multiple sets of tail wing plates can close or open the airflow port.

[0007] In the above technical solution, the height adjustment mechanism further includes a drive motor A, a lead screw, and a guide column. The mounting base has a mounting cavity inside, the guide column is fixedly connected inside the mounting cavity, the motion table is slidably connected to the guide column, the lead screw is threadedly connected to the motion table, the drive motor A is fixedly connected inside the mounting cavity, and the drive motor A is poweredly connected to the lead screw.

[0008] In the above technical solution, a guide plate is fixedly connected to the outer wall of the mounting base, and a guide groove is provided on the lifting sleeve to cooperate with the guide plate, with the guide plate located in the guide groove.

[0009] In the above technical solution, the two ends of the tail wing frame are fixedly connected to the mechanism housing, and the mechanism housing is fixedly connected to the lifting sleeve;

[0010] A rotating shaft is fixedly connected to the tail fin plate, and the two ends of the rotating shaft are respectively rotatably connected to the mechanism housing on both sides.

[0011] The tail fin adjustment mechanism is provided inside the housing of the mechanism, and the tail fin adjustment mechanism cooperates with the rotating shaft.

[0012] In the above technical solution, the tail wing adjustment mechanism includes a drive motor B and a synchronous connector. Multiple sets of rotating shafts within a set of mechanism housings are sequentially connected through the synchronous connector. The drive motor B is fixedly connected within the mechanism housing, and the drive motor B is poweredly connected to a set of rotating shafts.

[0013] In the above technical solution, the synchronous connector includes a synchronous pulley and a synchronous belt. The synchronous pulleys are fixedly connected to both sets of rotating shafts, and the two sets of synchronous pulleys are connected by the synchronous belt.

[0014] The beneficial effects of this utility model are:

[0015] 1. The height of the lifting sleeve can be adjusted through the height adjustment mechanism, which in turn adjusts the height of the rear wing mechanism. This allows the overall height of the rear wing to be automatically adjusted according to vehicle speed or wind resistance, thus optimizing downforce distribution.

[0016] 2. In the rear wing mechanism, multiple sets of rear wing plates are rotatably connected inside the rear wing frame. The rotation angle of the rear wing plates can be adjusted through the rear wing adjustment mechanism, thereby adjusting the airflow opening. When the airflow opening of the rear wing plate is closed, it can increase downforce, and when it is open, it can reduce wind resistance. The size of the airflow opening can also be controlled to adapt to different driving conditions. Attached Figure Description

The drive motor A302 is fixedly connected within the mounting cavity and is poweredly connected to the lead screw 303. The drive motor A302 can drive the lead screw 303 to rotate, thus causing the motion platform 301 to move linearly along the guide column 304.

[0025] Furthermore, the aforementioned motion table 301 and lifting sleeve 200 are fixedly connected by a connecting arm 201, so that when the motion table 301 moves in a straight line, it can drive the lifting sleeve 200 to move up and down.

[0026] Furthermore, a tail wing mechanism is provided between the two sets of lifting sleeves 200, so that the height of the tail wing mechanism can be adjusted when the lifting sleeves 200 move up and down.

[0027] Furthermore, the tail wing mechanism includes a tail wing plate 401, a tail wing adjustment mechanism, and a tail wing frame 402. Specifically, a tail wing frame 402 is fixedly connected between the two sets of lifting sleeves 200. An airflow port 403 is provided on the tail wing frame 402, and multiple sets of tail wing plates 401 are rotatably connected inside the airflow port 403. In addition, a tail wing adjustment mechanism is provided at one end of the tail wing frame 402.

[0028] Furthermore, both ends of the aforementioned tail wing frame 402 are fixedly connected to mechanism housings 404, which are fixedly connected to the lifting sleeve 200. A rotating shaft 405 is fixedly connected to the tail wing plate 401, and both ends of the rotating shaft 405 are rotatably connected to the mechanism housings 404 on both sides, thus realizing the rotatable connection of the tail wing plate 401.

The tail wing adjustment mechanism cooperates with the rotating shaft 405 to drive the tail wing plate 401.

[0029] Furthermore, in this embodiment, the tail wing adjustment mechanism includes a drive motor B406 and a synchronous connector 407.

The drive motor B406 is fixedly connected inside the mechanism housings 404 and is poweredly connected to a set of rotating shafts 405. In this way, the drive motor B406 can simultaneously drive multiple sets of tail wing plates 401 to rotate in the same direction. The aforementioned synchronous connector 407 is a combination of a synchronous pulley and a synchronous belt. That is, a synchronous pulley is fixedly connected to each of the two sets of rotating shafts 405, and the two sets of synchronous pulleys are connected by a synchronous belt.

[0030] Finally, in this embodiment, both drive motor B406 and drive motor A302 are connected to the vehicle control system. The vehicle control system can automatically control the operation of drive motor A302 and drive motor B406 according to the vehicle speed or manually according to the driver's needs, so as to realize the adjustment of the height of the rear wing mechanism and the rotation adjustment of the rear wing plate 401.
