Detailed description of the invention
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 present invention is based on the collapsible unmanned aerial vehicle ejecting frame that rubber band launches, comprise that cylindrical shell 2 and rubber band launch assembly, one end of cylindrical shell 2 offers launches mouth, and rubber band launches assembly and is installed on cylindrical shell 2.Rubber band launches assembly and comprises slurcam 5, guide rod 6, switch assembly, rubber band fixed mechanism 3 and rubber band (not shown).Rubber band fixed mechanism 3 is installed on and on cylindrical shell 2, is positioned at the one end of launching mouthful, switch assembly is installed on the other end on cylindrical shell 2, above this example of guide rod 6(is two) be installed between rubber band fixed mechanism 3 and switch assembly, slurcam 5 is slidedly arranged on guide rod 6, and one end of slurcam 5 is used for coordinating to realize percussion with switch assembly.Rubber band one end is connected on rubber band fixed mechanism 3, and the other end is connected on slurcam 5, realizes stretch-draw hold power by the slip of slurcam 5.
Slurcam 5 can be divided into two parts after assembling, and a part is in cylindrical shell 2 inside of launching, and another part exposes by the fluting on cylindrical shell 2, namely the outside extendible portion of slurcam 5.The interior section that is positioned at cylindrical shell 2 on slurcam 5 contacts with unmanned plane to be launched, and under rubber band effect, plays the effect that unmanned plane accelerates that promotes.Exterior section on slurcam 5, allows operating personal external force to hold power to rubber band, by pressing slurcam 5 to the motion of rubber band draw direction, completes the conversion of energy to elastic potential energy by outside acting.
In this enforcement, offer two and half holes of revealing on slurcam 5, these two holes, through the rubber band that launches use, make rubber band be fixedly connected with slurcam 5.
In the present embodiment, switch assembly comprises jump ring permanent seat 7, jump ring draw-in groove 8 and jump ring bayonet lock 9, and on jump ring permanent seat 7 fixed cylinders 2, jump ring draw-in groove 8 is located on jump ring permanent seat 7 and is positioned in the movement travel of slurcam 5, is provided with jump ring bayonet lock 9 in jump ring draw-in groove 8; On slurcam 5, be provided with slurcam rear portion trip 10 towards one end of switch assembly, slurcam rear portion trip 10 is provided with slurcam rear portion trip through hole 11, slurcam rear portion trip 10 is when by jump ring draw-in groove 8, jump ring draw-in groove 8 entirety upward movement under action of the spring, the jump ring bayonet lock that is overshooting shape 9 in the middle of jump ring draw-in groove 8 can, through slurcam rear portion trip through hole 11, form locking.
In this enforcement, rubber band fixed mechanism 3 is actually a winding device, and two middle through holes, through the two of launching rubber band, have three screws on device, by the screwing of screw, make anchor fitting up and down two can step up rubber band.
In the present embodiment, further comprise rubber band separating plate 4, rubber band separating plate 4 is sheathed on guide rod 6, makes to launch rubber band and passes through from rubber band separating plate 4 tops.This design can avoid two parallel rubber bands that launch to twist together in unmanned aerial vehicle ejecting is gone out to launching cradle process, hinders fuselage and normally leaves.Simultaneously, can also play the position-limiting action to whole acting process, rubber band can play certain buffer action, when slurcam 5 and rubber band are together from upwards accelerated movement of jump ring permanent seat 7, gradually near emission port, now whole acting process closes to an end, but the kinetic energy that slurcam 5 has needs to dissipate, rubber band passes through the upside of rubber band separating plate 4 from the downside of slurcam 5, so now have one deck rubber band between slurcam 5 and rubber band separating plate 4, rubber band diameter has about 15mm, enough plays buffer action.
In the present embodiment, cylindrical shell 2 adopts stainless material, for expendable weight, is not affecting under requirement of strength, uses the design of hollow out.If adopted as aluminium is material, with corresponding processing technology, can reduce to a greater degree weight, and can strengthen the adhesive ability generally spraying paint, thereby can select cheap spraying paint, and then the reduction cost that sprays paint and bring.
In the present embodiment, also further comprise bracing frame 1, bracing frame 1 is positioned on cylindrical shell 2 towards the one end of launching mouthful, is used for being positioned on ground forming and supporting.Bracing frame 1 is made up of aluminum alloy, and weight is lighter; Bracing frame 1 comprises many strut bars, is welded by aluminium alloy rod, has both ensured the intensity of strut bar and overall stability, also reduces as much as possible the weight of single unit system simultaneously, alleviates the burden of carrying.Strut bar and ground contacting part are divided into tip, can insert soft earth and sand ground, increase the adhesive ability to ground, improve launcher stability.
When use, take off launching cradle from back, open bracing frame 1 and stand on the ground, unmanned plane to be launched is folding, fill in launching cradle by launching mouth.Meanwhile, thumb and root, by being pressed in the extendible portion of slurcam 5 at launching cradle upper surface, push away to launching rubber band draw direction.Slurcam 5 moves down, and near jump ring permanent seat 7, when jump ring draw-in groove 8 is locked slurcam 5, whole dead work completes.Now thumb is pressed jump ring draw-in groove 8, and under rubber band drives, slurcam 5 is along guide rod 6 steering handle unmanned planes from launching a mouthful release.
In this process, whole motion process can divide two parts.The first step: operating personal moves to rubber band draw direction by pressing slurcam 5, complete the conversion of energy to elastic potential energy by outside acting, slurcam rear portion trip 10 is through jump ring draw-in groove 8, jump ring draw-in groove 8 entirety upward movement under action of the spring, projection jump ring bayonet lock 9 in the middle of jump ring draw-in groove 8, can pass slurcam rear portion trip through hole 11.Because the motion of slurcam rear portion trip through hole 11 is limited on the axis of symmetry of jump ring permanent seat 7, so the back seat of slurcam 5 has also just been limited in jump ring permanent seat 7 tops allocation really.So just complete similar " bullets loading " process.Second step: press when hand the part that jump ring draw-in groove 8 tops exceed permanent seat downwards, jump ring draw-in groove 8 moves downward, the projection jump ring bayonet lock 9 in the middle of groove will leave slurcam rear portion trip through hole 11, thereby discharge slurcam 5, also just complete " percussion " process.
Below be only the preferred embodiment of the present invention, protection scope of the present invention is also not only confined to above-described embodiment, and all technical schemes belonging under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
