Description
Technical field
The present invention is applied to the fixing device installing radar on SUAV and in particular to one kind is airborne sharp
Optical radar fixing device.
Background technology
Laser radar, as environment sensing unit, is equivalent to the eyes of verification machine, for improve unmanned plane from
Main ability has important function.The ultimate principle of the laser radar being at present relatively commonly used to SUAV is,
Its top is Infrared laser emission device, and the direction of the launch is vertically downward.Middle part is an axicon, will hang down
Directly incident laser level is to external reflectance.Reflected light is reflected by the object back laser range finder, by receiving convex lens
Mirror and prism are received by light sensitive diode, thus resolving object distance.Such laser radar, due to
Internal structure complex precise, easily because external shock and collision etc. are destroyed.
Content of the invention
The technical problem to be solved in the present invention is to protect laser radar safely and effectively work on unmanned plane
Make, there is provided a kind of airborne laser radar is fixed on the fixing device of SUAV.
The fixing device of the present invention, for installing laser radar on SUAV, including upper cover plate, bottom
Seat, support, adjutage and 45 ° of tiltwings, support vertical connects upper cover plate and base；Close in upper cover plate
A pair of adjutage is had on the diagonal of support side；Respectively there are 45 ° of tiltwings this adjutage end, at this
45 ° of tiltwing lower surfaces are provided with plane mirror；Some screws are had on base, is fixed by the screw of inner ring
Fixing device is arranged on upper surface on front side of unmanned aerial vehicle body by the screw of outer ring by the base of laser radar；
Described laser radar is arranged between upper cover plate and base.
Described upper cover plate and base adopt engraved structure.
Described fixing device one 3D printing molding, material is polylactic acid.
There is reinforcement on described adjutage.
, by between bottom surface placed on it for laser radar and bottom surface, upper bottom surface is along laser measurement scope for this device
Two winglets, two 95 ° of winglet centerlines are stretched out in border, above post plane mirror by position glancing incidence
Laser beam reflect to underface, so that laser radar being capable of height in survey aircraft flight course.Dress
The strip projection putting winglet upper surface can lift the bending stiffness of winglet, thus improving laser reflecting measurement
Stability.The upper bottom surface of device is designed with big opening to mitigate its overall weight.Bed-plate dimension is equal up and down
Than laser radar section greatly it is therefore an objective to laser radar can be protected when aircraft collision is toppled over from shock.
Beneficial effects of the present invention：This installation weight is light, and stabilized structure is reasonable in design, can effectively consolidate
Determine airborne laser radar.
Brief description
Fig. 1 is the structural representation of airborne laser radar fixing device of the present invention.
Specific embodiment
As shown in figure 1, a kind of specific embodiment of airborne laser radar fixing device, including：
1 and 2 upper cover plates 1 being respectively laser radar fixing device and base 2, upper cover plate 1 and base 2 are equal
Be designed with big opening with the overall weight of alleviator, and size big all than laser radar section it is therefore an objective to
Laser radar can be protected from shock when aircraft collision is toppled over.
3 is the support that upper cover plate 1 and base 2 connect, and perpendicular to upper cover plate 1 and base 2, its length is
The height of institute's fixed laser radar.
4 is to have a pair of adjutage, device winglet upper table on the diagonal of support 3 side in upper cover plate 1
The reinforcement in face can lift the bending stiffness of winglet, thus improving the stability of laser reflecting measurement.
5 is 45 ° of tiltwings of adjutage 4, and angle at 45 °, simultaneously posts plane mirror over the ground with horizontal segment,
The laser beam of position glancing incidence is reflected to underface, so that laser radar can survey aircraft fly
Height during row.In the case of graphic display unit, the height measured by laser radar is
H=(d-d0)·cos(roll)·cos(pitch)
In formula, the laser radar that H measures for single beam laser is relatively high to ground, and d restraints the survey of laser distance for this
Value, d0For the distance at laser radar center to mirror surface center, roll is body roll angle, pitch
For the body angle of pitch.
6 is the screw of base 2, and inner ring screw 6 is used for the base of fixed laser radar, and outer ring screw 6 is used for
This device is fixed on unmanned plane surface.
Device adopt 3D sculpting software Solidworks software design, after the completion of adopt U.S. Makerbot 2X
Three-dimensional printer prints and generates, and material therefor is polylactic acid.
