Summary of the invention
The purpose of this utility model is, provides a kind of simple in structure, and reliability height, slowing-down brake are apart from weak point, and be reusable, with low cost is used for the slowing-down brake mechanism that unmanned plane slides dolly.
The utility model discloses a kind of slowing-down brake mechanism that unmanned aerial vehicle ejecting system slides dolly that is used for, comprise slowing-down brake plate, dolly locating part, braking elastic, elastic termination connecting element, elastic wrap and elastic turning part, wherein the slowing-down brake plate is fixed on ejection system and slides on the dolly; The dolly locating part is fixed on ejection system and slides on the guide rail; Elastic wrap and elastic turning part are fixed on ejection system and slide on the guide rail, and two terminations of braking elastic are fixed on the elastic wrap by elastic termination connecting element.
Further, described slowing-down brake plate is provided with the elastic position-limited trough that is circular-arc with the end that the braking elastic contacts, the width after the width of this position-limited trough twines greater than the braking elastic.
Further, sliding the dolly locating part slides on the guide rail by being bolted to ejection system.
Further, the distance from the elastic wrap to elastic turning part less than from elastic turning part to the distance that slides the dolly locating part.
Further, the braking elastic is through being wrapped in after certain stretching on elastic wrap and the elastic turning part; The braking elastic is stretched to 1.1-1.2 times of drift; Braking elastic maximum tension length is 2 times of drift; The braking elastic repeatedly twines on elastic wrap and elastic turning part.
The utility model uses energy is kept the weighing apparatus law, and the kinetic energy that slides the dolly high-speed motion is converted to the elastic potential energy of braking elastic, and then realizes the slowing-down brake effect slide dolly.
The utility model provides is used for the slowing-down brake mechanism that unmanned plane slides dolly and has following outstanding feature:
1, simple in structure, easy to use, fitting process is simple and easy to use;
2, can be by selecting the industrial elastic of different stiffness factors, after repeatedly twining applicable to the unmanned aerial vehicle ejecting system of different take-off weights;
3, with low cost, repeatedly reusable, can prolong this mechanism service life greatly by changing the braking elastic;
4, weight is little, and area occupied and volume are little, to the structural weight that alleviates a whole set of ejection system and take volume and play a positive role.

The specific embodiment
Shown in Figure 1A, 2, be used for unmanned aerial vehicle ejecting system and slide dolly slowing-down brake mechanism and comprise slowing-down brake plate 7, braking elastic 5, elastic termination connecting element 4, elastic wrap 3, elastic turning part 2 and slide dolly locating part 6.Slowing-down brake plate 7 is fixed on ejection system and slides on the dolly, slides dolly locating part 6 and slides on the guide rail 1 by being bolted to ejection system.Braking elastic 5 is an industrial elastic, and is fixing tight one end head with an elastic termination connecting element 4 earlier during assembling, then elastic wrap 3 inserted in another termination, shown in A-A view among Figure 1B.Braking elastic 5 inserts the elastic wrap 3 of an other side behind elastic turning part 2, and so forth after twice, after above-mentioned braking elastic 5 is stretched to about 1.1 to 1.2 times of drifts, with another elastic termination connecting element 4 its termination is fixed on the other elastic wrap 3, like this, promptly finished the installation of sliding dolly slowing-down brake mechanism.
In the unmanned plane emission process, slide dolly together with unmanned plane under the ejection force effect along ejector rail 1 high-speed motion.After unmanned plane arrives certain coasting speed, unmanned plane with slide dolly and separate, break away from ejection system and begin the process of climbing.But slide dolly high-speed motion still on guide rail this moment, run into slowing-down brake mechanism until continuing to slide.
As shown in Figure 3, drive braking elastic continuation sliding state scheme drawing for sliding dolly.Be positioned at and slide dolly foremost owing to slide dolly slowing-down brake plate 7, described slowing-down brake plate 7 is provided with the elastic position-limited trough 8 that is circular-arc, and the width of the width of position-limited trough 8 after twining greater than braking elastic 5.When sliding dolly slowing-down brake plate 7 and begin contact braking elastic 5, braking elastic 5 is stuck in the position-limited trough 8 in the slowing-down brake plate 7.Slide dolly slowing-down brake plate 7 drive braking elastics 5 and continue to slide, according to the energy conservation law, the kinetic energy that slides dolly is converted to the elastic potential energy of braking elastic gradually.Slide dolly and under the effect of braking elastic 5, slow down gradually, slide until stopping, being still on the ejector rail 1.And then finish the slowing-down brake process that unmanned plane slides dolly.Slide dolly locating part 6 for to slide the inhibiting device of dolly, in case on-slip row dolly skids off ejector rail 1 at ejector rail 1 line of travel.
Above-mentioned embodiment of the present utility model can not be thought restriction that the utility model claim is done; if those skilled in the art does not need performing creative labour to make corresponding variation by inspiration of the present utility model, all should fall in the protection domain of the utility model claim.
