Abstract
The invention provides a kind of hook lock shock absorber, for the bumper and absorbing shock of the coaster of unmanned aerial vehicle ejecting system, described hook lock shock absorber comprises torsion spring, bearing pin, locks button and pedestal; Wherein pinned connection locks button and pedestal, and the torsion spring be arranged on bearing pin acts on pedestal with certain predetermincd tension and locks button.The invention has the beneficial effects as follows: after unmanned plane and coaster emit on ejection system, be in high-speed motion, this device can be used as the buffer deceleration requirement that coaster completes coaster after release unmanned plane, avoids the rigid collision of coaster and catapult-launching gear.
Description
technical field:
The invention belongs to ejection system field, be specifically related to a kind of hook lock shock absorber of ejection system, be particularly useful for the buffering of the quick highly reliable ejection system of unmanned plane.
background technology:
Unmanned aerial vehicle ejecting system is the product of advanced unmanned air vehicle technique manoevreability development.It is made up of launcher, energy resource system, coaster, shock absorber etc., the polytype advanced unmanned plane of ejectable, becomes the important trend of new-type weapon and equipment development.Unmanned aerial vehicle ejecting system has following technological merit: (1) volume is little, powerful.Do not need large-area airstrip, emission process is short, and takeoff speed is high; (2) manoevreability and viability strong.Whole unmanned plane can be arranged on transport agent (cycling start, warship, locomotive etc.), makes it have good maneuvering performance; (3) low cost of manufacture.Production and processing requires easily, at sustainable supply in wartime; (4) strong adaptability.Have under any climatic conditions, rise and fall gully, hills, swampy terrain implement fight ability.
Crusherbull zone technical study is one of important content of unmanned aerial vehicle ejecting technology.In ejection system trial-production debug process, coaster needs install accurate electronic metering equipment additional, if there is no buffer device for collision, after ejection process terminates, coaster can move on very high speed, certainly will cause the rigid contact of coaster and launcher arrester, the sophisticated electronics being easy to like this cause coaster loads lost efficacy.Therefore actv. shock absorber must be designed to realize the buffering reduction of speed of coaster.
The shock absorber such as damping spring, cushion blocking has been widely used in the equipment of different purposes.But for the bumper and absorbing shock of unmanned aerial vehicle ejecting system coaster, many buffer device for collision because short, the complex structure of buffer distance, the loaded down with trivial details application limited in unmanned aerial vehicle ejecting field of installation.
summary of the invention:
Technology of the present invention is dealt with problems and is: overcome middle-size and small-size unmanned aerial vehicle ejecting system ubiquitous collision problem in trial-production debug process, a kind of novel unmanned aerial vehicle ejecting system hook lock shock absorber is proposed, while sophisticated electronics completes measurement at a high speed, shock absorber has good energy-absorbing effect, longer buffer distance, and well the supratrochlear sophisticated electronics of protection is not damaged; In addition, to it also avoid the rigidity of the rigid contact of coaster and launcher and steel rope stretching for this shock absorber.
Technical solution of the present invention is: on launcher front end; the rubber cord adopting rigidity to be greater than 1000Nm is fixed on launcher two ends for the obstruction to coaster; coaster designs a hook lock shock absorber; after coaster collides with rubber cord at a high speed; hook lock shock absorber can catch on rubber cord; rubber cord is made to become as a whole with coaster; the large damping of the large rigidity of rubber cord is utilized to complete crusherbull zone to coaster; crash acceleration can be made so greatly to reduce, reach the object of electronic equipment accurate on protection coaster.
Formal at structure installment, hook lock shock absorber is bolted to be fixed with coaster, and in hook lock shock absorber, the rigidity of torsion spring is core parameter.After the rigidity size of torsion spring need ensure that rubber cord enters hook lock, and after rubber cord bounce-back, hook lock shock absorber is locked, and makes rubber cord become as a whole with hook lock, completes the pooling feature of hook lock.The cushion effect be subject to according to rubber cord can obtain the maximum rigidity of torsion spring divided by the arm of force locking button, can obtain (i.e. the turnaround time of torsion spring) minimum rigidity of torsion spring according to the run duration of rubber cord in pedestal, then the rigidity value of torsion spring gets appropriate value within the scope of this.
Except bearing pin and torsion spring, other equipment of hook lock shock absorber adopts aluminium to process.
After unmanned plane and coaster emit on ejection system, be in high-speed motion, this device can be used as the buffer deceleration requirement that coaster completes coaster after release unmanned plane, and avoid the rigid collision of coaster and catapult-launching gear, tool of the present invention has the following advantages:
(1) structure is simple.This smart structural design, total only needs five parts, and install compact, buffering effect is good;
(2) quality is light.Primary structural component pedestal and left-hand thread lock all adopt aluminium to process, the complete meet requirements of intensity, and its quality is also comparatively light, does not form impact qualitatively, therefore can not affect the result of a measurement of electronic machine to coaster.
(3) volume is little.The space that this hook lock shock absorber takies is very little, can not the effect of interference test.

Detailed description of the invention
Following content elaborates to the specific embodiment of the present invention in conjunction with Figure of description:
As shown in Figure 1, the pedestal 5 of hook lock shock absorber is fixed on coaster by bolt hole 6, bearing pin 3 connects locks button 4 and pedestal 5, torsion spring 2 acts on pedestal 5 with certain predetermincd tension and locks button 4, the two ends of rubber cord 1 are fixed on car launcher, after hook lock shock absorber knocks rubber cord with coaster with high speed, lock button 4 and be subject to the rubber cord power effect contrary with sense of motion, lock button 4 around bearing pin 3 left-hand revolution, such rubber cord 1 just enters the inner space of hook lock smoothly, the predetermincd tension had due to torsion spring 2 is larger, lock button 4 and can return to original position under the effect of torsion spring 2 again, so just ensure that rubber cord becomes to be integrated with coaster, utilize the large damping of the large rigidity of rubber cord to complete damping object rubber cord and enter the process of hook lock shock absorber as shown in Figure 2.
When needing to carry out experiment next time after completing buffering, only need catch the part left-hand revolution locking the handle that button 4 exposes, rubber cord is withdrawn from the space of hook lock device.
The present invention is applied in the debugging of certain type unmanned aerial vehicle ejecting system.
Tool of the present invention has the following advantages: structure is simple: this smart structural design, and total only needs five parts, and install compact, buffering effect is good; Quality is light: primary structural component pedestal and left-hand thread lock all adopt aluminium to process, the complete meet requirements of intensity, and its quality is also comparatively light, does not form impact qualitatively, therefore can not affect the result of a measurement of electronic machine to coaster.(3) volume is little: the space that this hook lock shock absorber takies is very little, can not the effect of interference test.
Those skilled in the art, can be improved according to the above description or be converted, and all these improve and convert the protection domain that all should belong to claims of the present invention.
