Description
Technical field
It the utility model is related to a kind of regulating device, and in particular to a kind of automobile tail fin regulating device.
Background technology
Racing car has strict demand to security caused by air drag, stable direction in design, because of its specific use
Vehicle is sought to possess higher steering stability and earth-grasping force during higher speed.However, since the kerb weight of racing car is lighter,
Very high is asked to the steering of racing car, braking, dynamic equilibrium height, general requirement aerodynamics external member induced drag is small, and lift resistance ratio is high,
The barycenter of vehicle is low.Automobile tail fin refers to that car trunk covers, and rear end fills the protrusion of form duck tail, belongs to automobile air
A part in power external member；The effect of automobile tail fin is exactly in galloping, air drag is formed one downwards
Pressure, offset lift as far as possible, effectively control air-flow under pressure, air resistance coefficient is accordingly reduced, increase running at high speed for automobile
Stability；Since empennage can reduce the air drag of automobile, high speed car installs empennage additional also to be had necessarily for saving fuel oil
Help；Also make the shape of automobile more beautiful at the same time, play certain decoration function.Installed on current automobile be typically
Non-adjustable empennage so that the efficiency that empennage is provided is not too high.
The content of the invention
The utility model aim is to provide a kind of automobile tail fin regulating device for overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of automobile tail fin regulating device, it includes
Vehicle speed sensor, the flow sensor installed in automobile tail, respectively with the vehicle speed sensor and the flow sensor phase
The controller and fin assembly of connection, the fin assembly include pedestal, installed in the base bottom and with the control
Multiple elevating mechanisms that device is connected, be erected in the pedestal upper surface and spaced two end plates, by horizontally disposed
Connecting shaft be installed at least fantail wing between two pieces of end plates, be connected with the empennage and with connecting shaft mistake
Open up the push-pull rod put and the motor being connected with the push-and-pull boom end.
Optimally, the controller is microcontroller.
Optimally, the elevating mechanism is electric lift.
Optimally, the empennage has two fans, they are correspondingly arranged up and down.
Further, define larger between upper empennage, with the pedestal with the pedestal spacing in the two fan empennages
Away from it is less be lower empennage；The push-pull rod has more, and the every push-pull rod passes through lower empennage and the upper end and the upper tail
Wing bottom surface is hinged.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Automobile tail fin regulating device, by vehicle speed sensor, flow sensor measures speed and air velocity with to controller send pair
The lifting of signal control fin assembly and the steering of empennage answered, so as to meet racing car under high-speed motion to empennage efficiency
Transform effect, allows racing car to give play to more preferable speed ability in competition field.
Brief description of the drawings
Attached drawing 1 is the structure diagram of the utility model automobile tail fin regulating device.
Embodiment
The utility model preferred embodiment is described in detail below in conjunction with attached drawing：
Automobile tail fin regulating device as shown in Figure 1, mainly includes controller 1, flow sensor 2,3 and of vehicle speed sensor
Fin assembly 4 etc..
Wherein, the installation site of vehicle speed sensor 3 has multiple choices, and headstock, in-car and the tailstock are all right；It can be direct
It is existing using vehicle, one can also be newly increased again；Flow sensor 3 is installed on the afterbody of automobile, such as on some automobiles
Equipped with luggage-boot lid, can directly be installed at this time on luggage-boot lid.Controller 1 respectively with vehicle speed sensor 3 and stream
Fast sensor 2 is connected, and is handled for receiving the signal that they are produced；It can be directly entirely to the middle control module of automobile
On, usually using microcontroller.Fin assembly 4 is then liftably installed on the afterbody of automobile, it includes pedestal 41, is installed on
41 bottom of pedestal and be connected with controller 1 multiple elevating mechanisms 42, be erected at 41 upper surface of pedestal and spaced two
Block end plate 43, an at least fantail wing 44 and empennage 44 by horizontally disposed connecting shaft 45 between two end plates 43
Be connected and with the push-pull rod 47 of 45 stagger setting of connecting shaft and the motor 46 being connected with 47 end of push-pull rod.When vehicle not
When driving, vehicle speed sensor 3 provides signal, this signal reaches microcontroller after A/D converter is handled, and microcontroller is according to signal
Output control signal passes to motor 46 through D/A converter（Not rotary state）, at this time push-pull rod 47 do not work, empennage 44 is kept
It is static；It can be so hidden in vehicle body body in racing car startup stage, empennage 44, reduce windage；Until vehicle is promoted to 30km/s.
When Vehicle Speed is more than 30km/s, push-pull rod 47 rises certain height under the drive of motor 46 so that empennage 44 encloses
Corresponding angle is rotated around connecting shaft 45；Elevating mechanism 42 at the same time（Usually electric lift）Work is so that fin assembly 4 reveals
Go out car body.Flow sensor 3（That is air velocity transducer）It is to be directed under the larger situation for having an impact empennage 44 of some wind speed to do
The auxiliary adjustment gone out, when wind speed is more than 20km/h, actively intervention adjusts and reduces empennage 44, by vehicle speed sensor during less than 20km/
3 Signal Regulation empennage, this can improve influence of the environment to empennage.The conversion angle of attack can so be reached to meet racing car at a high speed
To the transform effect of empennage efficiency under movement, racing car is allowed to give play to more preferable speed ability in competition field.
In the present embodiment, empennage 44 has two fans（They are correspondingly arranged up and down）, define the two fantail wings 44 in pedestal 41
Spacing is larger for upper empennage, and less with 41 spacing of pedestal is lower empennage；Push-pull rod 47 is spaced two, and every pushes away
Pull rod 47 is hinged through lower empennage and the upper end with upper empennage bottom surface, push-pull rod 47 through need at lower empennage and lower empennage into
Row is hinged, therefore lower empennage needs to stop space in push-pull rod 47 through place.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
