Specific embodiment
The present invention provides a kind of vehicle-mounted unmanned aerial vehicle concave surface type landing platforms, with reference to the accompanying drawings of the specification and are embodied Mode is described in detail the present invention.
As shown in Figure 1, vehicle-mounted unmanned aerial vehicle concave surface type landing platform provided by the invention, including airplane parking area 2, pedestal 4 are gentle Rush column.Airplane parking area 2 is in recessed cambered surface, and center is equipped with the lock piece realizing locking by rotation or opening.Pedestal 4, which is placed in, to stop The lower section on machine level ground 2, is fixed on the top plate of car body.Bumper post is at least one, is placed between airplane parking area 2 and pedestal 4, delays Rushing column includes telescopic segment, and the periphery of bumper post is cased with spring 7.Telescopic segment is compressed after bumper post is under pressure, so that stopping Machine level ground 2 declines, and impact force when declining to unmanned plane buffers.
Unmanned plane 1 is impacted by airborne, airplane parking area 2, forces the telescopic segment of bumper post to be shunk, impact force is buffered It absorbs, unmanned plane 1 is realized along the cambered surface slide downward of airplane parking area 2, and using the rotation of lock piece automatically under the effect of gravity Automatic positioning.
As shown in Figures 2 and 3, the bottom surface of pedestal 4 is equipped with mounting groove and sliding slot, and card slot and track 5 are clamped, sliding slot sliding It is arranged on push rod 6, mounting groove and sliding slot are arranged in parallel.Using mounting groove and track 5 come firm banking 4, while utilizing push rod 6 Guiding and positioning action are played, facilitates installation, effectively improves installation effectiveness.Push rod 6 can use electrodynamic type, pneumatic type or hydraulic Formula can push pedestal 4 that airplane parking area 2 is driven to move along track 5.
Track 5 includes cylindrical body and the trapezoid seat that cylindrical body lower part is arranged in, and the central angle of the section circle of cylindrical body is greater than 180 degree.The structure of cylindrical body can effectively prevent deviating from out of card slot, improve bonding strength, and the bottom surface of trapezoid seat is with larger Fixed-area, can be improved structural stability, and by pressure dissipation.
Track 5 is two, and is symmetrical arranged about push rod 6, further increases fixed stability.
Airplane parking area 2 includes the gentle cambered surface 21 and the windproof cambered surface 22 for the excircle that gentle cambered surface 21 is arranged at center, is put down The radian of slow cambered surface 21 is less than the radian of windproof cambered surface 22.Gentle cambered surface 21 is used to provide smooth landing radian for unmanned plane 1, And windproof cambered surface 22 can be by most of powerful airflow-resistive outside, and internal gas flow is made to form turbulent flow, reduces air-flow to nobody The influence of machine 1.
Bumper post includes first bumper post 30 at center and multiple second bumper posts 31 around the first bumper post 30, and second Bumper post 31 is arranged along the excircle of gentle cambered surface 21.Set multiple for bumper post, the supporting point of airplane parking area 2 is evenly distributed on Multiple positions are conducive to the structure of airplane parking area 2 steadily and buffer.
As shown in Figure 3 and Figure 4, push rod includes outer tube 64 and screw rod 63 in outer tube 64 is arranged in screw thread, and outer tube 64 is equipped with Fixing seat 61, fixing seat 61 and pedestal 4 are fixed, and the other end of screw rod 63 is connected with motor 62, and motor 62 is arranged on top plate.Electricity Machine 62 drives screw rod 63 to rotate, and the generation of outer tube 64 slides straightly and drives pedestal 4 mobile, to adjusting pedestal 4 to suitable position It sets.
One end of fixing seat 61 is equipped with mounting hole, and outer tube 64 penetrates in mounting hole, and bolt passes through fixing seat 61 and outer tube 64 And it is fixed.
The top plate of car body is equipped with lifter plate, and pedestal 4 is fixed on lifter plate, and lifter plate uses fluid pressure type or vapour-pressure type. Lifter plate can drop to car, and operator can carry out part exchanging, such as replacement battery, operation to unmanned plane 1 as needed It is convenient.
The top surface of airplane parking area 2 is equipped with the sliding rail that land for unmanned plane 1, and sliding rail facilitates after unmanned plane landing along sliding rail in Heart sliding improves stability when unmanned plane 1 lands.
The present invention sets concave surface type for airplane parking area, can glide automatically along sliding rail after unmanned plane landing, and be automatically positioned extremely Final position, positioning is simple, high-efficient without carrying out accurate point location, positioning and landing, and it is close in the stream of people to be suitable for cruiser It spends big region to shuttle everywhere, facilitates processing burst or accident, there is very strong adaptibility to response to all kinds of emergency cases, It can be applied to automobile, logistic car, engineering rescue vehicle, emergency break down lorry, truck, the panzer etc. that other have similar demand;Simultaneously The airplane parking area of concave surface type can be such that air-flow weakens, and generate turbulent flow, influence of the air-flow to unmanned plane be reduced, when enhancing unmanned plane lands Stability;And the bumper post below airplane parking area can effectively buffer impact force when unmanned plane landing, to unmanned plane and shutdown Level ground plays a protective role, and effectively improves the stability of structure, prolongs the service life, market prospects are very wide.
The invention is not limited to above-mentioned preferred forms, and anyone should learn that is made under the inspiration of the present invention Structure change, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
