[0010] The selection mechanism includes a main control unit located in the base and a brake sensor for detecting brake signals.

[0024] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0025] Currently, most mainstream vehicle autonomous driving systems use LiDAR installed on the roof and windshield. This not only detracts from the vehicle's aesthetics and increases its drag coefficient, but also increases the risk of traffic accidents. Statistics show that a large proportion of traffic accidents are caused by obstructed vision from vehicles in front, resulting in a limited field of vision. Solving this problem would significantly reduce the accident rate. Example 1

[0026] See Figs. 1 to 3 This utility model discloses a rear wing fusion sensor platform device, including a rear wing 3, a bracket 8, and a base 9. The rear wing consists of a front rear wing 31 and a rear rear wing 32, which are connected by a hinge-like rotating connection mechanism to achieve the effect of raising the rear rear wing 32 independently while keeping the front rear wing 31 stationary. The front rear wing 31 has multiple grooves 10 for mounting a camera 1 and a sensor 2, allowing the sensor 2 and camera 1 to be hidden inside the rear wing 3. This does not affect the vehicle's appearance and effectively expands the vehicle's monitoring field of view, enhancing its perception of the surrounding environment.

[0027] The bracket 8 includes a first bracket 81 and a second bracket 82. The first bracket 81 is used to fix the front rear wing 31 to the base 9, forming a load-bearing structure to ensure the overall structural stability against wind resistance at high speeds. The base 9 integrates a pneumatic drive unit, and the rear rear wing 32 is rotatably connected to the pneumatic drive unit via the second bracket 82. For example, based on changes in vehicle speed and driving mode, the pneumatic drive unit can automatically adjust the angle of the rear rear wing 32 (raising or lowering it). Raising it increases downforce to improve grip, while lowering it reduces wind resistance and optimizes energy consumption, thereby optimizing the vehicle's aerodynamic performance and improving its stability and handling. Example 2

[0028] See Fig. 1 In one embodiment of this utility model, both the front rear wing 31 and the rear rear wing 32 are made of composite carbon fiber material. Its lightweight and high-strength characteristics not only reduce vehicle weight and improve fuel efficiency, but also significantly enhance the durability and impact resistance of the rear wing 3. Multiple cameras 1 and one sensor 2 are also installed in the groove of the front rear wing 31 via bolt assemblies. The cameras 1 are symmetrically distributed at equal distances on both sides of the sensor 2 to ensure the symmetry and comprehensiveness of the monitoring range.

[0029] Both the camera 1 and the sensor 2 are rotatable, allowing for adjustment of the monitoring angle as needed, thereby enhancing adaptability to the surrounding environment. Compared to traditional solutions, the spacing between the cameras 1 in this embodiment is larger, resulting in better 3D recognition performance.

[0030] In a further embodiment of this utility model, baffles 11 are fixedly connected to both sides of the front tail wing 31 to reduce the impact of airflow disturbance on the sensor 2.

[0031] See Fig. 2 and Fig. 3The pneumatic drive unit includes a pneumatic mechanism 5 and a gas pump 6. The pneumatic mechanism 5 includes a pneumatic knob 51, which is connected to the rear tail fin 32 via a second bracket 82. The gas pump 6 is located inside the base 9 and provides power to the pneumatic mechanism 5 through a gas transmission channel, thereby driving the pneumatic knob 51 to rotate and dynamically adjust the angle of the tail fin 3. For example, after being filtered and treated, external air first enters the gas pump 6, which pressurizes the gas to provide sufficient pressure to drive the subsequent pneumatic mechanism 5.

[0032] In a further embodiment of the present invention, the device further includes a selection mechanism. The pneumatic mechanism 5 is provided with dual air inlets, namely air inlet A and air inlet B, respectively corresponding to the forward and reverse rotation of the pneumatic knob 51. These are connected to the gas pump 6 through a gas transmission channel.

[0033] The selection mechanism is equivalent to a small control center, including a main control unit 7 and a brake sensor 4 located in the base 9. The brake sensor 4 is used to detect brake signals, and its signal output terminal, as well as the control terminals of the gas pump 6 and the controllable valve, are electrically connected to the main control unit 7. The main control unit 7 is connected to the signal output terminals of the camera 1 and the sensor 2.

[0034] The gas transmission channel is also equipped with a controllable valve (such as a check valve), whose opening and closing state is controlled by the main control unit 7 to ensure that the airflow can only flow from the gas pump 6 to the selection mechanism.

[0035] In a further embodiment of this utility model, when the brake sensor 4 detects a braking action, the main control unit 7 triggers the controllable valve on the gas transmission channel connected to air inlet A to open and the controllable valve on the gas transmission channel connected to air inlet B to close, so that the airflow in the gas pump 6 enters the pneumatic mechanism 5 through air inlet A, driving the pneumatic knob 51 to rotate clockwise, thereby causing the rear tail wing 32 to rise. Conversely, when the brake sensor 4 does not detect a braking action, the main control unit 7 triggers the controllable valve on the gas transmission channel connected to air inlet B to open and the controllable valve on the gas transmission channel connected to air inlet A to close, so that the airflow in the gas pump 6 enters the pneumatic mechanism 5 through air inlet B, driving the pneumatic knob 51 to rotate counterclockwise, thereby causing the rear tail wing 32 to descend.

[0036] In a further embodiment of this utility model, the brake sensor 4 can be a magnetoelectric brake pedal position sensor or a piezoresistive brake pressure sensor. The magnetoelectric brake pedal position sensor is usually installed on the brake pedal to detect changes in the displacement or angle of the brake pedal; the piezoresistive brake pressure sensor generates a signal by sensing changes in braking pressure; the pneumatic mechanism 5 adopts a pneumatic rotary actuator, which can be divided into a vane-type pneumatic rotary actuator and a gear-type pneumatic rotary actuator, both of which are suitable for this scenario.

[0037] When the pneumatic mechanism 5 is a vane-type pneumatic rotary actuator, compressed air enters the actuator from the air inlet A. The air drives the vanes to rotate, and the vanes drive the shaft connected to them to rotate, outputting rotary motion. For example, when air enters from the air inlet A, the pneumatic knob 51 connected to the shaft rotates clockwise; when compressed air enters from the air inlet B, the vanes rotate in the opposite direction, driving the pneumatic knob 51 connected to the shaft to rotate counterclockwise.

[0038] When the pneumatic mechanism 5 is a gear-type pneumatic rotary actuator, compressed air enters the actuator and drives the internal gear structure to move. Through the meshing transmission of the gears, the pneumatic knob 51 connected to the output shaft is rotated. The air inlet A and the air inlet B control the clockwise and counterclockwise rotation of the pneumatic knob 51, respectively. Example 3

[0039] A vehicle includes a vehicle-mounted control system and a rear wing fusion sensor platform device as described in Embodiments 1 and 2. The vehicle-mounted control system is communicatively connected to the camera 1, the sensor 2, and the main control unit 7.

[0040] In summary, the device described in this utility model achieves dual-function synergistic optimization: On the one hand, the front rear wing 31 integrates a camera 1 and a sensor 2, whose symmetrical layout and large spacing significantly expand the monitoring field of view, effectively covering the area in front of and to the sides of the vehicle, reducing blind spots of traditional distributed sensors; on the other hand, the rear rear wing 32, through the linkage of the pneumatic mechanism 5 and the brake sensor 4, raises during braking to increase downforce, thereby improving tire grip and braking stability, thus achieving the purpose of assisting braking. Simultaneously, the dynamic adjustment of the pneumatic knob 51 can optimize the angle of the rear rear wing 32 according to vehicle speed and driving mode, thereby balancing wind resistance and downforce requirements. The main control unit 7 integrates data from the sensor 2, braking signals, and vehicle status to achieve intelligent synergy between environmental perception and aerodynamic adjustment, ensuring driving safety while maintaining the streamlined appearance of the vehicle body through the integrated rear wing design, balancing functional practicality and aesthetic design.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
