Description
Technical field
This utility model relates to unmanned plane instrument, is specifically related to a kind of SUAV shock resistance undercarriage.
Background technology
Along with the development of unmanned air vehicle technique, the application of unmanned plane is more and more extensive.Due to unmanned facility
There is the advantage such as unmanned, volume is little, and mobility is good by application, can be divided into military and civilian.
Military aspect, unmanned plane is divided into reconnaissance plane and target drone.Unmanned plane+sector application, is that unmanned plane is real
Just need；At present taking photo by plane, agricultural plant protection, the application in the field such as mapping, greatly expanded unmanned
The purposes of machine itself.
No matter prior art is many rotors or fixed-wing unmanned plane has a process reclaimed, and
Removal process is again the greatest risk stage, that cause due to misoperation with ground impact or flying
System accident power down during row, all can occur sharp impacts with ground, break unmanned plane, because
This, designing a kind of shock resistance undercarriage just has critically important using value.
Utility model content
This utility model provides a kind of SUAV shock resistance undercarriage, solves in art
SUAV Landing Buffer or the problem damaged that is hit of falling, concrete technical scheme is as follows:
A kind of SUAV shock resistance undercarriage, including upper bush, lower sleeve, valve of holding one's breath, bullet
Spring and charge valve, described upper bush top is connected with unmanned plane, and bottom and lower sleeve are socketed, described on
Being provided with spring between sleeve and lower sleeve, described lower sleeve bottom center is provided with push rod, described upper bush
Bottom center has through hole, described in valve of holding one's breath be arranged in upper bush and slide up and down along upper bush, institute
Stating charge valve and be arranged on upper bush side, gases at high pressure are filled with in upper bush by charge valve, described on
Sleeve bottom is additionally provided with the venthole outside connection.
Further, the end face of the described gas check valve shop front upwards sleeve bottom is provided with cannelure, this ring
It is placed with sealing ring in shape groove.
Further, described lower sleeve side is provided with gathering sill, described upper bush side correspondence gathering sill
Position be provided with prevent that two sleeves from departing from interior and stay nail.
Further, described venthole quantity is some.
Further, described push rod height is less than spring heights.
It should be noted that this utility model is discussed in two kinds of situation:
When unmanned plane normal landing, the speed of whereabouts is controlled and unhappy, and undercarriage impact is relatively
Little, play general cushioning effect, its operation principle is, unmanned plane body declines with undercarriage, connects
During tread surface, lower sleeve is motionless, and upper bush moves downward compression spring, absorbs impact kinetic energy, Jin Erqi
To certain cushioning effect, now push rod does not contact the valve of holding one's breath of lower sleeve, and gases at high pressure are not released
Put.
When the unexpected power down of unmanned plane, unmanned plane can run out of steam, and equipment falling speed is quickly, unmanned
Machine body drives undercarriage rapid decrease, when sleeve bottom props up spike face contiguously instantly, unmanned plane machine
Body drives upper bush rapid decrease, is first that spring is compressed absorption portion of energy, and body continues to decline
Push rod in lower sleeve backs down downwards the valve of holding one's breath of upper bush, and the gases at high pressure in upper bush quickly lead to
Cross in valve of holding one's breath flows downwardly into lower sleeve and spray to ground by venthole again, simultaneously form an air
Pad, this process will consume most impact kinetic energy, and machine plays cushioning effect, and protection is unmanned
The safety of machine equipment.
Beneficial effect:
This utility model provides a kind of SUAV shock resistance undercarriage, the fall that reply unmanned plane is different
Fall situation, has two kinds of different solutions, substantially increases the safety in utilization of unmanned plane.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below
The accompanying drawing used required in embodiment or description of the prior art will be briefly described, it is clear that
Ground, the accompanying drawing in describing below is only embodiments more of the present utility model, common for this area
From the point of view of technical staff, on the premise of not paying creative work, it is also possible to obtain according to these accompanying drawings
Other accompanying drawing.
Fig. 1 is this utility model overall structure figure.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below to this
Technical scheme in utility model embodiment is clearly and completely described, it is clear that described reality
Executing example is a part of embodiment of this utility model rather than whole embodiments.Based on this utility model
In embodiment, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly falls into the scope of this utility model protection.
Embodiment 1:
A kind of SUAV shock resistance undercarriage as shown in Figure 1, including upper bush 1, lower sleeve 2,
Holding one's breath valve 3, spring 4 and charge valve 5, described upper bush 1 top is connected with unmanned plane, bottom with
Lower sleeve 2 is socketed, and is provided with spring 4, described lower sleeve 2 between described upper bush 1 and lower sleeve 2
Bottom center is provided with push rod 6, and described upper bush 1 bottom center has through hole 7, described in hold one's breath valve 3
Sliding up and down along upper bush in being arranged on upper bush 1, described charge valve 5 is arranged on upper bush 1 side,
