Technical field
The present invention relates to airplane design technical fields, specifically, being related to a kind of for protecting the banjo fixing butt jointing of wing.
Background technique
Unmanned plane recycling is broadly divided into running landing and parachuting landing two ways.Sliding race landing is higher to site requirements.
Parachuting is mostly used to recycle in order to keep unmanned plane recycling easy small and medium size unmanned aerial vehicles, the side landed with damper or air bag buffering
Formula.Due to being influenced by crosswind, orographic factor, when aircraft landing, is easy to tilt to fuselage two sides, makes wing with biggish speed
Degree lands, and wing is caused to damage, and causes economic loss, influences normal flight.
For this reason, it may be necessary to develop it is a kind of for protecting the banjo fixing butt jointing of wing, aircraft landing inclination when pass through docking structure
Damage energy-absorbing, reduce the speed contacted to earth of wing, so that wing be avoided to be damaged, or even destroy, and banjo fixing butt jointing replacement is just
Prompt, save the cost, improves the maintainability and durability of unmanned plane.
Summary of the invention
In order to avoid the shortcomings of the prior art, overcome small and medium size unmanned aerial vehicles parachuting land when, by crosswind, landform because
The influence of element, airframe are tilted to two sides, when wing being made to land with biggish speed, wing are caused to damage, and influence normally to fly
Capable problem, the present invention propose a kind of for protecting the banjo fixing butt jointing of wing；The banjo fixing butt jointing structure is simple, light-weight, and more
Change convenient, it can be achieved that unmanned plane safely and reliably lands.
The technical solution adopted by the present invention to solve the technical problems is: including middle outer wing connector, outer wing connector, rapid wear
Part, screw, to connecting bolt and burnished bolt, it is characterised in that middle outer wing connector and middle outer spar are connected by screw, and outer wing connects
Head is connected by screw to outer wing, and vulnerable part is connected between middle outer wing connector and outer wing connector；
The vulnerable part is equipped with through-hole and overload breakage slot, and the width of vulnerable part is connect on the inside of lug with middle outer wing connector
Width, outer wing joint side end slot width match, and vulnerable part both ends can be inserted on the inside of middle outer wing connector connection lug and outer respectively
In wing joint side end slot, vulnerable part one end is bolted with middle outer wing connector by docking, and the other end and outer wing connector pass through essence
System is bolted, and overload breakage slot position is in the position that middle outer wing connector is connect with outer wing connector on vulnerable part, unmanned aircraft parachute descent
When Lu Fasheng tilts, vulnerable part energy-absorbing is broken, and reduces the speed that wing contacts to earth.
Overload breakage slot on the vulnerable part is setting symmetrical above and below, and overload breakage slot cross section is concave structure.
Beneficial effect
It is proposed by the present invention a kind of for protecting the banjo fixing butt jointing of wing, by middle outer wing connector, outer wing connector and vulnerable part
Composition, wherein middle outer wing connector is connect by screw with middle outer spar, and outer wing connector is connect by screw with outer wing, vulnerable part
It is connected between outer wing connector and outer wing connector.Vulnerable part one end is bolted with middle outer wing connector by docking, vulnerable part
The other end is connect with outer wing connector by burnished bolt, and vulnerable part is equipped with through-hole and overload breakage slot, the width point of vulnerable part
Lug inboard width is not connect with middle outer wing connector and outer wing joint side end slot width matches, vulnerable part both ends can be inserted into respectively
On the inside of middle outer wing connector connection lug and in outer wing joint side end slot, and overload breakage is equipped at the position of two connectors connection
Slot, when unmanned aircraft parachute descent landing tilts, vulnerable part energy-absorbing is broken, and reduces the speed that wing contacts to earth, and reduces machine
Wing structure is damaged.
The present invention is for protecting the banjo fixing butt jointing structure of wing simple, light-weight and easy to change, save the cost, improves
The maintainability of unmanned plane.Realize that unmanned plane safely and reliably lands.

Specific embodiment
The present embodiment is a kind of for protecting the banjo fixing butt jointing of wing.
Refering to fig. 1~Fig. 4, the present embodiment are used to protect the banjo fixing butt jointing of wing, by middle outer wing connector 1, outer wing connector 2,
Vulnerable part 3, screw 4 form connecting bolt 5 and burnished bolt 6, wherein middle outer wing connector 1 is solid by screw 4 with middle outer spar
Fixed connection, outer wing connector 2 are connect with outer wing by screw 4, and vulnerable part 3 is connected between middle outer wing connector 1 and outer wing connector 2.
In the present embodiment, vulnerable part 3 is equipped with through-hole and overload breakage slot 7, and the width of vulnerable part 3 and middle outer wing connector connect
Connect lug inboard width, outer wing joint side end slot width matches, pluggable middle 1 connection of outer wing connector respectively of 3 both ends of vulnerable part
On the inside of lug and in 2 side slot of outer wing connector, 3 one end of vulnerable part with middle outer wing connector 1 by being connect to connecting bolt 5, the other end
It is connect with outer wing connector 2 by burnished bolt 6, overload breakage slot 7 is located at middle outer wing connector 1 and connects with outer wing connector on vulnerable part 3
The position connect；When unmanned aircraft parachute descent landing tilts, vulnerable part energy-absorbing is broken, and reduces the speed that wing contacts to earth.
In the present embodiment, for vulnerable part 3 on the basis of guaranteeing unmanned plane normal flight, design has overload breakage slot.Rapid wear
Overload breakage slot 7 on part 3 is setting symmetrical above and below, and concave-shaped structure is processed into 7 cross section of overload breakage slot.
When installation, middle outer wing connector 1 is fixedly connected by screw 4 with middle outer spar, and outer wing connector 2 is by screw 4 and outside
Spar is fixedly connected, and vulnerable part 3 is connect with outer wing connector 2 by burnished bolt 6.
When flight, vulnerable part 3 is with middle outer wing connector 1 by connecting to connecting bolt 5.When unmanned aircraft parachute descent lands, by side
The influence of wind, landform, tilts, and when wing is landed with biggish speed, vulnerable part energy-absorbing is sent out from overload breakage slot
It is raw to destroy, the speed that wing contacts to earth is reduced, wing is reduced and is damaged, vulnerable part is easy to change, saves maintenance cost, improves nothing
Man-machine maintainability.
