Abstract
The utility model relates to a linear adjusting device of throttle, especially a linear adjusting device of unmanned aerial vehicle throttle belongs to unmanned aerial vehicle throttle control technical field. The utility model discloses a linear adjusting device of unmanned aerial vehicle throttle, includes servo motor, and steering wheel and throttle are acted as go -between, and steering wheel and servo motor output shaft, throttle act as go -between one end and fix on steering wheel, the last annular wire winding groove that is provided with of steering wheel, annular wire winding groove is concentric with the servo motor output shaft, and the winding is acted as go -between at annular wire winding inslot to the throttle. The utility model discloses an actively beneficial effect lies in and since set up on steering wheel with the endocentric annular wire winding groove of servo motor output shaft, the winding is acted as go -between at annular wire winding inslot to the throttle, this kind of design changes servo motor's angle and changes the linear output that changes along the girth with annular wire winding groove into, makes throttling more smooth -going.
Description
Technical field
The utility model is related to a kind of throttle linear regulation device, particularly a kind of unmanned plane throttle linear regulation device,
Belong to unmanned plane Throttle Opening Control technical field.
Background technology
At present, depopulated helicopter is extensively utilized in civil area, particularly in plant protection, takes photo by plane, entertains
In field.In existing depopulated helicopter, a kind of common structure of accelerator control device is by servomotor, steering wheel rocking arm, throttle
Bracing wire is constituted, and in use, servomotor receives the control signal that controller transmits, and turns an angle, and drives steering wheel
Rocking arm switchs to linearly operating, pulls acceleration cable to control the size of throttle.But there is problems with this kind of control mode：Servo electricity
What machine received is angular distance signal, and rotation is carried out in units of angle, after steering wheel rocking arm is changed into linearly operating, due to
The angle of steering wheel rocking arm and acceleration cable is not fixed, when steering wheel rocking arm initial angle is a, after servomotor rotational angle b, throttle
Bracing wire change length c with the mathematical relationship of steering wheel rocking arm length d be：c=d*（cos(a+b)-cosa）, clearly may be used from above formula
There is not linear changing relation, this is for reality between angle b rotating with length c and servomotor of finding out acceleration cable variation
It is precisely controlled unmanned plane throttle in the operation of border and bring very high operation easier.
Content of the invention
For overcoming problem above of the prior art, the utility model provides a kind of unmanned plane throttle linear regulation dress
Put.
For realizing the purpose of this utility model, the technical scheme of employing is as follows：A kind of unmanned plane throttle linear regulation device,
Including servomotor, steering wheel and acceleration cable, steering wheel is connected with servo motor output shaft, and acceleration cable one end is fixed on steering wheel
On, described steering wheel is provided with ring winding groove, ring winding groove is concentric with servo motor output shaft, and acceleration cable is wrapped in ring
In shape winding slot；Further, described steering wheel is by the cylinder group of two coaxial discs parallel to each other and two disk bodies of connection
Become, described cylinder is coaxially connected with two disk bodies, one of disk is provided with and axially vertical breach, sets in breach
It is equipped with the locking device of fixing acceleration cable, described acceleration cable is wrapped on the cylinder between two disks, one end is by solid
Determine device to be fixed on steering wheel.
Positive beneficial effect of the present utility model is, concentric with servo motor output shaft due to being provided with steering wheel
Ring winding groove, acceleration cable is wrapped in ring winding groove, this design by the angle change of servomotor be changed into along with
The linear convergent rate of the perimeter change of ring winding groove, when the angle of servomotor change is b, the variation length c=of acceleration cable
π bd/360, wherein d are the diameter of ring winding groove, because π and d is definite value, by above formula it is apparent that the change of acceleration cable
Change the linear variation relation of angle b of length c and servomotor change.
Brief description
Fig. 1 is the accelerograph adjusting device schematic diagram using steering wheel rocking arm.
Fig. 2 adjusts the schematic diagram of throttle for steering wheel rocking arm.
Fig. 3 is the accelerograph adjusting device schematic diagram with winding slot.
Specific embodiment
In order to more fully explain enforcement of the present utility model, embodiment of the present utility model presented below, these are real
Applying example is only to elaboration of the present utility model, does not limit scope of the present utility model.
In conjunction with accompanying drawing further details of explanation to the utility model, it is labeled as in accompanying drawing：1. accelerator rod；2. steering wheel
Rocking arm；3. steering wheel；4. locking device；5. acceleration cable.As can be seen：A kind of unmanned plane throttle linear regulation device, including
Servomotor, steering wheel 3 and acceleration cable 5, steering wheel 3 is connected with servo motor output shaft, and acceleration cable one end is fixed on steering wheel,
Ring winding groove is provided with described steering wheel, ring winding groove is concentric with servo motor output shaft, and acceleration cable is wrapped in annular
In winding slot, above for the technical solution of the utility model, Fig. 3 shows a kind of embodiment of this technical scheme, in figure rudder
Disk 3 is sheave, by two coaxial discs parallel to each other and the cylinder that connects two disk bodies forms, described cylinder and two
Disk body is coaxially connected, and one of disk is provided with and axially vertical breach, is provided with fixing acceleration cable in breach
Locking device 4, in the present embodiment, locking device is screw rod, and screw rod can be fixed in the screwed hole on sheave, and described throttle draws
Line is wrapped on the cylinder between two disks, and one end is fixed on steering wheel 3 by locking device, substantially can be seen that from figure,
When the angle of servomotor change is b, the variation length c=π bd/360 of acceleration cable, wherein d are the straight of ring winding groove
Footpath, because π and d is definite value hence it is evident that the variation length of acceleration cable and the rotational angle of servomotor are linear.With figure
3 compare, and Fig. 2 is the method controlling throttle using steering wheel rocking arm in prior art, from figure 2 it can be seen that of the prior art
The structure of steering wheel rocking arm 2 open out pull bar 1, when steering wheel rocking arm rotational angle is b, the variation length c of bracing wire is c=d*（cos
(a+b)-cosa, both non-linear relations, therefore, the linear throttle regulative mode that the utility model provides eliminates former regulation
The defect of mode, makes throttle adjustment be more easy to manipulate.
