[0002] In windy weather, vehicles are often disturbed by crosswinds, especially when driving on highways or viaducts in high and open areas. Crosswinds will have a greater impact on vehicle driving and may even blow the vehicle off course, thus creating a potential traffic accident.

[0003] At present, the vehicle deviation assistance technology is mainly based on the camera's forward detection and automatic steering lane keeping technology, which has a significant effect on slow deviation. However, the deviation caused by strong winds is a rapid and short-term deviation, and this lane keeping technology is not applicable, and may even be counterproductive. How to solve the interference of strong winds on vehicle driving stability has always been a problem that plagues the industry. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-4 , an embodiment provided by the present invention:

[0019] A mechanical vehicle shark fin and a vehicle, comprising: a shark fin body 100, a chassis 200, a connecting rod 300, a bearing 400, a damping device 500 and a fixing device 600.

[0020] The fin body 100 is arranged on the chassis 200 and is fixedly connected to one end of the connecting rod 300. The bearing 400 is nested on the connecting rod 300 and is fixedly connected to the chassis 200. The damping device 500 is located in the chassis 200, fixed to the chassis 200, and connected to the other end of the connecting rod 300. The fin body 100 can rotate in the same horizontal plane. When the fin body 100 rotates, the damping device 500 provides a rotational damping force for the fin body 100 and provides an automatic self-correcting force.

[0021] The chassis 200 is provided with a guide rail groove 210, and the fin body 100 is provided with a first guide pin 110 and a second guide pin 120 matching the guide rail groove 210, so that the connection between the fin body 100 and the chassis 200 can be more secure.

[0022] The fixing device 600 includes a locking device 610 and a locking slot 620. The locking device 610 is arranged on the fin body 100, and the locking slot 620 is located on the chassis 200. When the locking device 610 and the locking slot 620 are locked, the fin body 100 and the chassis 200 remain relatively consistent. When the locking device 610 and the locking slot 620 are opened, the fin body 100 can realize transmission and complete the corresponding angle change.

[0023] The main principle of this embodiment is that the fin body 100 continuously adjusts its angle with the vehicle according to the direction and strength of the strong wind, thereby changing the aerodynamic flow direction of the vehicle and reducing the interference of the strong wind on the vehicle driving. Based on this principle, the damping device 500 in this embodiment can be specifically divided into three embodiments for introduction.

[0024] In the first embodiment, the damping device 500 includes a first torsion spring 512, a second torsion spring 513 and a first shell 511. The first torsion spring 512 and the second torsion spring 513 are placed in vertically opposite directions and are fixedly connected to the first shell 511 respectively. The first shell 511 is arranged in the chassis 200 and is fixed to the chassis 200. The first torsion spring 512 and the second torsion spring 513 are both connected to the connecting rod 300.

[0025] In the second embodiment, the damping device 500 includes a first reed 522, a second reed 523, a first clamping plate 524, a second clamping plate 525, a second housing 521, and a shift bar 526. The first reed 522 and the second reed 523 are arranged on both sides of the housing and support the first clamping plate 524 and the second clamping plate 525.

[0026] The second housing 521 is disposed in the chassis 200 and fixed to the chassis 200 . The shift bar 526 is located between the first clamping plate 524 and the second clamping plate 525 , and the center thereof is connected to the connecting rod 300 .

[0027] The wind blowing laterally and the longitudinal driving resistance of the vehicle form a combined force and act on the vehicle body and the fin body 100. The angle of the fin body 100 changes due to the disturbance of the combined force. The damping device 500 provides a damping force for the fin body 100 with the changed angle, so that the fin body 100 maintains a certain angle, and the air flow is diverted based on the angle, so that the two sides of the vehicle are evenly disturbed by the air, thereby achieving the effect of stabilizing the vehicle body.
