Specific embodiment
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
As shown in Fig. 1～Fig. 6, the collapsible unmanned aerial vehicle ejecting frame that the present invention is launched based on rubber band, including cylinder 2 and rubber band
Ejection assembly, one end of cylinder 2 offers ejection mouth, and rubber band ejection assembly is installed on cylinder 2.Rubber band ejection assembly includes pushing away
Dynamic plate 5, guide rod 6, switch assembly, rubber band fixed mechanism 3 and rubber band (not shown).Rubber band fixed mechanism 3 is installed on cylinder 2
It is located at one end of ejection mouth, switch assembly is then installed on the other end on cylinder 2, and more than one guide rod this example of 6(is two
Root) be installed between rubber band fixed mechanism 3 and switch assembly, pushing plate 5 is slidedly arranged on guide rod 6, one end of pushing plate 5 be used for
Switch assembly cooperation is to realize firing.Rubber band one end is connected on rubber band fixed mechanism 3, and the other end is connected in pushing plate 5, leads to
Tensioning storage power is realized in the slip crossing pushing plate 5.
Pushing plate 5 can be divided into two parts after mounting, and inside the cylinder 2 of ejection, another part passes through cylinder to a part
Fluting on body 2 exposes, that is, the outer extension part of pushing plate 5.In pushing plate 5 be located at cylinder 2 interior section with treat
The unmanned plane of ejection contacts, and under rubber band effect, plays the effect promoting unmanned plane to accelerate.Exterior section in pushing plate 5,
Then allow operating personnel to store power with external force to rubber band, moved to rubber band draw direction by pressing pushing plate 5, by outside acting
Complete the conversion to elastic potential energy for the energy.
In this enforcement, pushing plate 5 offers the holes of two and half dew, this two holes pass through the rubber band of ejection so that skin
Muscle is fixedly connected with pushing plate 5.
In the present embodiment, switch assembly includes jump ring fixed seat 7, jump ring draw-in groove 8 and jump ring bayonet lock 9, and jump ring fixed seat 7 is solid
On safety barrel body 2, jump ring draw-in groove 8, in jump ring fixed seat 7 and in the movement travel of pushing plate 5, is provided with jump ring draw-in groove 8
Jump ring bayonet lock 9；Pushing plate 5 is provided with promotion postlaminar part trip 10 towards one end of switch assembly, promotes postlaminar part trip 10
It is provided with promotion postlaminar part trip through hole 11, promotes postlaminar part trip 10 when by jump ring draw-in groove 8, jump ring draw-in groove 8 entirety exists
Move upwards under spring effect, the jump ring bayonet lock 9 in overshooting shape in the middle of jump ring draw-in groove 8 can be through promotion postlaminar part trip through hole
11, form locking.
In this enforcement, rubber band fixed mechanism 3 is actually a winding device, and two middle through holes pass through ejection rubber band
Two, three screws are had on device, by screwing so that the two panels up and down of fixing device can step up skin to screw
Muscle.
In the present embodiment, further include rubber band separating plate 4, rubber band separating plate 4 is sheathed on guide rod 6 so that launching skin
Muscle passes through above rubber band separating plate 4.This design can avoid two parallel ejection rubber bands that unmanned aerial vehicle ejecting is being gone out ejection
Twist during frame together, hinder fuselage normally to leave.Simultaneously additionally it is possible to play the position-limiting action to whole process of doing work, skin
Muscle can play certain cushioning effect, when pushing plate 5 and rubber band together accelerate upwards from jump ring fixed seat 7, gradually leans on
Nearly emission port, now entirely acting process closes to an end, but the kinetic energy that pushing plate 5 has needs to dissipate, and rubber band is from promotion
The upside of rubber band separating plate 4 is passed through in the downside of plate 5, so now there being one layer of rubber band between pushing plate 5 and rubber band separating plate 4,
Rubber band diameter has about 15mm, plays cushioning effect enough.
In the present embodiment, cylinder 2 adopts stainless material, in order to mitigate weight, under not affecting intensity requirement, uses
The design of hollow out.If being material using such as aluminium, and corresponding processing technology, then can reduce weight to a greater degree, and
The adhesive force of general spray painting can be increased, such that it is able to from cheap spray painting, and then reduce the cost that spray painting brings.
In the present embodiment, still further comprise bracing frame 1, bracing frame 1 is located at the one end on cylinder 2 towards ejection mouth, use
Support to be positioned over to be formed on ground.Bracing frame 1 is made up of aluminium alloy, lighter in weight；Bracing frame 1 includes many support bars, that is,
It is welded by aluminium alloy rod, both ensure that the intensity of support bar and overall stability, also reduce overall simultaneously as far as possible
The weight of device, mitigates the burden carrying.Support bar and ground contacting part are divided into tip, may be inserted into soft soil and sand
Ground, increases the adhesive force to ground, improves launcher stability.
During use, take off launching cradle from back, open bracing frame 1 and stand on the ground, unmanned plane to be launched is folded, by bullet
Loophole fills in launching cradle.Meanwhile, thumb and root are pressed against the extension in launching cradle upper surface for the pushing plate 5, to ejection
Rubber band draw direction pushes away.Pushing plate 5 moves down, close jump ring fixed seat 7, when 8 pushing plates 5 of jump ring draw-in groove are locked, entirely
Preparation completes.Now thumb pressing jump ring draw-in groove 8, under rubber band drives, pushing plate 5 is along guide rod 6 direction unmanned
Machine is released from ejection mouth.
In the process, whole motion process can divide two parts.The first step: operating personnel pass through press pushing plate 5 to
Rubber band draw direction moves, and completes the conversion to elastic potential energy for the energy from outside acting, promotes postlaminar part trip 10 to pass through card
Spring draw-in groove 8, jump ring draw-in groove 8 is overall to move under the action of the spring upwards, and the projection jump ring bayonet lock 9 in the middle of jump ring draw-in groove 8 can pass through
Promote postlaminar part trip through hole 11.Because the motion promoting postlaminar part trip through hole 11 is limited in the symmetrical of jump ring fixed seat 7
On axle, so the back seat of pushing plate 5 has also been limited to the determination position of jump ring fixed seat 7 top.This completes class
Like " bullets loading " process.Second step: when hand press down on jump ring draw-in groove 8 top exceed fixed seat part, jump ring draw-in groove 8 to
Lower motion, the projection jump ring bayonet lock 9 in the middle of groove will leave promotion postlaminar part trip through hole 11, thus discharging pushing plate 5, also just complete
Become " percussion " process.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonging under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention, should be regarded as the protection of the present invention
Scope.
