Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and
Embodiment, is further elaborated to this utility model.Should be appreciated that described herein being embodied as
Example, only in order to explain this utility model, is not used to limit this utility model.Additionally, basis disclosed below
As long as it is the most permissible that technical characteristic involved in each embodiment of utility model does not constitutes conflict each other
It is mutually combined.
As it is shown in figure 1, include engine oil according to the auto extinguishing protection device of one embodiment of this utility model
Door steel wire rope 1, throttle steering wheel steering wheel 2, throttle steering wheel holding wire 3, throttle steering wheel supply lines 4, throttle steering wheel
5, engine misses line 6, microswitch 7 and movable contact spring 8.
Movable contact spring 8 is arranged on throttle steering wheel steering wheel 2 can be with its synchronous axial system, and on this steering wheel disk body 2 is even
The throttle stay cord 1 having regular length it is connected between contact with engine throttle, preferably steel wire rope, can be at this rudder
Dish disk body 2 rotate in along with this junction point away from or control throttle close to throttle position by this throttle stay cord 1
Size.Preferably having hole in the circumference of periphery at steering wheel disk body, stay cord connects by this hole is fixing, makes
Obtaining this present position, hole is junction point.
In the present embodiment, as it is shown in figure 1, preferably steering wheel clockwise turns to become big so that throttle and then control to send out
The direction of motivation, is referred to as forward in the present embodiment.On the contrary, counterclockwise rotation is to reversely rotate.
During steering wheel disk body rotates, junction point is throttle zero-bit with throttle position part recently, and steering wheel disk body is in this oil
Time at door zero-bit, the electromotor of aircraft is in idling mode.Correspondingly, rotating forward, junction point is the most suitable
Hour hands move so that throttle pullled by stay cord thus throttle strengthens；Reversely rotating, junction point moves the most counterclockwise
Dynamic so that stay cord is pullled throttle amplitude and reduced until minimizing during throttle zero-bit, rotates then the most counterclockwise
Can reversely make stay cord pull throttle thus throttle be likely to strengthen, until making movable contact spring abut with microswitch
Contact.
The reverse rotation being positioned at this junction point that movable contact spring 8 is arranged on steering wheel disk body 2 and throttle is diminished
Side, is i.e. positioned at the reverse rotation side of junction point, as being to be positioned at the counter clockwise direction side of junction point in Fig. 1.
Microswitch and the flame-out connection of electromotor, the microswitch crimping normally opened static contact at movable contact spring can
So that the flame-out circuit of electromotor is connected, complete engine dies.In one embodiment, fine motion is opened
Closing 7 is static contact open in usual, the preferably static contact open in usual of band roller.Roller type static contact open in usual switchs
Stable height, it is possible to when engine work, ensureing under the state that unmanned vehicle vibrations are bigger will not misconnection
Leading to makes electromotor shut down.
Microswitch 7 is arranged on aircraft body and is located close near throttle steering wheel steering wheel 2, and with flight
The flame-out circuit 6 of the electromotor of device connects.Specifically, microswitch relative to junction point be arranged on steering wheel with dynamic
The position of contact homonymy, in its circumference the angle of spacing junction point with steering wheel steering wheel counter-rotating certain angle thus
Movable contact spring is made to touch to contact with microswitch 7 and be advisable.
Microswitch and throttle zero-bit angle apart, the most specifically limit, can concrete according to steering wheel
Specification or parameter select, such as in the present embodiment can be in the range of 10-20 ° preferably, more preferably
In the range of 12-18 °, the most preferably 15 °.I.e. rudder throttle steering wheel steering wheel 2 is driven and reversely rotates and return to
Throttle zero-bit and continue to rotate backward 10-20 °, in the range of more preferably 12-18 °, the most preferably 15 °
After, just make the movable contact spring on steering wheel just contact with microswitch, so that flame-out line conduction.
In one embodiment, the outer surface of steering wheel 2 having draw-in groove, described movable contact spring is arranged on described card
In groove.Movable contact spring is arranged in the draw-in groove of throttle steering wheel steering wheel and is fastened by bolt and nut.Draw-in groove can make dynamic touching
Sheet is easily installed, by fastening make movable contact spring contact normally opened static contact when more stable, will not be by bullet
The impact of power, it is possible to work smoothly.
Flight control system sends throttle steering wheel 5 in instruction control Fig. 1 and makes its mechanical movement, and wherein instruction is
Referring to that flight control system sends allows throttle steering wheel steering wheel 2 in Fig. 1 return to throttle zero-bit and to continue reversely to turn
Dynamic so that the instruction that movable contact spring can contact with microswitch.Such as in one embodiment, can reversely rotate
15 degree of angles.
When unmanned vehicle control program judges that unmanned vehicle is in runaway condition, throttle steering wheel will be passed through
Holding wire 3 controls the steering wheel 2 on throttle steering wheel 5 and returns to throttle zero point and continue to rotate respective angles, drives peace
The movable contact spring 8 being contained on throttle steering wheel steering wheel crimps the static contact 7 under normally open so that it is connect electromotor
Flame-out circuit 6 reaches the purpose of engine dies.
Of the present utility model realization by control unmanned vehicle electromotor auto extinguishing protection device ought be unmanned
Engine power can be cut off in time to unmanned vehicle to carry out lost-control protection when aircraft is out of hand.
The control to throttle steering wheel of the unmanned vehicle flight control system, described control refers to that throttle steering wheel returns to
Zero-bit also continues to reversely rotate.Normally opened static contact installs the position on body near throttle steering wheel steering wheel, its
Feature be movable contact spring controlled motion as pressing component, press normally opened static contact and static contact connected, it is achieved be right
The flame-out parking of electromotor.
As it will be easily appreciated by one skilled in the art that and the foregoing is only preferred embodiment of the present utility model,
Not in order to limit this utility model, all made within spirit of the present utility model and principle any amendment,
Equivalent and improvement etc., within should be included in protection domain of the present utility model.
