Background
Catapult takeoff is a takeoff mode of the current unmanned aerial vehicle, and the mode is suitable for the condition that the takeoff distance is very short. The catapult-assisted take-off system mainly comprises two parts: unmanned aerial vehicle and ejection frame. And a corresponding mechanical interface is required to be designed at the connecting part of the ejection rack and the unmanned aerial vehicle. The mechanical interfaces which are widely used at present mainly have the following three designs: circular slot type design, square slot type design, and hook type design. Fig. 1a-1c show the mechanical interface structure of the existing unmanned aerial vehicle ejection system.
In which fig. 1a shows a circular groove design and fig. 1b shows a square groove design. Circular slot type design and square groove type design all can be terminal through spacing design at the slide rail launch the in-process and produce thrust to unmanned aerial vehicle, and vertical and horizontal spacing effect is very good. However, the above two configurations have disadvantages: in order to balance the head raising moment generated by the unmanned aerial vehicle due to the rise of the speed in the ejection stage, the circular groove type design and the square groove type design need longer lengths of the sliding blocks (a1 and b1) and the sliding rails (a2 and b2), and the weight of the unmanned aerial vehicle can be increased when the unmanned aerial vehicle is installed on a machine body; in addition, longer slider and slide rail length can make unmanned aerial vehicle the condition of jamming appear in the ejection process, perhaps slide rail and slider in the twinkling of an eye that slider and slide rail separation can cause mutual extrusion at the end because of unmanned aerial vehicle's new line moment, damage slider or slide rail.
FIG. 1c shows a hook design, which has the advantage of a relatively short slider length, reducing body weight; the contact distance between the sliding blocks (c1, c2) and the sliding rails (c3, c4) is short, and the separation process of the sliding blocks and the sliding rails can be smoother. However, the hook design has the disadvantages of: in order to balance the head raising moment of the unmanned aerial vehicle in the acceleration process, a corresponding butt joint part needs to be designed below each sliding block, and at the moment that the unmanned aerial vehicle leaves the rail, the rear sliding block c2 and the front sliding rail c4 are in collision risk.
Aiming at the advantages and disadvantages of the three designs, the invention provides a novel connection structure of an unmanned aerial vehicle ejection system, which can simultaneously take the advantages of light weight, simple structure, good pitching moment balance effect, smooth off-track and the like into consideration.

Indeed, various embodiments of the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.
In one exemplary embodiment of the present disclosure, a connection structure of a drone ejection system is provided.
Fig. 2 is a schematic view of a connection structure of an unmanned aerial vehicle ejection system according to an embodiment of the disclosure. As shown in fig. 2, the connection structure of the unmanned aerial vehicle ejection system of the present disclosure includes a slide block and a slide rail 30, wherein the slide block is two blocks in front and back, including a front slide block 10 and a rear slide block 20, the front slide block 10, the rear slide block 20 and the bottom of the unmanned aerial vehicle body are fixedly connected, and the slide rail 30 and the ejection device are fixedly connected. Because the slide block adopts the front and back longitudinal separation layout, the aircraft is equivalently restrained at two points, and the pitching motion of the aircraft is limited, so that the pitching moment balance effect is good, and the off-track is smooth.
Specifically, the slide rail 30 includes an upper partition plate 301 and a lower partition plate 302 arranged along the vertical direction, a front sliding groove matched with the front slider 10 is arranged at the front end of the lower partition plate 302, a rear sliding groove matched with the rear slider 20 is arranged at the front end of the upper partition plate 301, and the front end of the upper partition plate 301 is fixedly connected with the rear end of the lower partition plate 302 through a connecting plate 303. The upper surface of slide rail 30 adopts the face contact with preceding slider base 101 and back slider base 201, bears unmanned aerial vehicle self gravity. The front sliding block longitudinal partition plate 102 and the rear sliding block longitudinal partition plate 202 are inserted into the groove of the sliding rail 30, so that the unmanned aerial vehicle is limited to move in the transverse direction.

The front slider longitudinal partition plate 102 between the front slider base 101 and the front slider lower baffle plate 103 can be inserted into the groove of the sliding chute 30 to slide, so the thickness between the front slider base 101 and the front slider lower baffle plate 103 needs to be equal to the thickness of the slide rail lower partition plate. In some embodiments, the pitch angle of the airplane may become larger during the ejection process, the lift force may increase due to acceleration during the ejection process of the airplane, and when the lift force is greater than the weight of the airplane body, the lower baffle of the slider will abut against the lower surface of the lower baffle of the slide rail, so that the distance between the base 101 of the front slider and the lower baffle 103 of the front slider may be set to be 2mm to 5mm greater than the thickness of the lower baffle of the slide rail 30.
Fig. 3b is a front view of a front slider of a connection structure of an unmanned aerial vehicle ejection system according to an embodiment of the disclosure. As shown in fig. 3b, the whole "i" type structure that is of preceding slider 10, the preceding slider base 101 on upper portion and the preceding slider lower baffle 103 of lower part carry out the upper and lower direction spacing to slide rail 30, prevent that the unmanned aerial vehicle from taking place the ascending motion of vertical direction to the ejector rack installation in-process and unmanned aerial vehicle in the ejection process, preceding slider longitudinal baffle 102 is used for restricting the motion of unmanned aerial vehicle on transversely. In order to reduce the weight, the width of the lower baffle plate 103 of the front slide block is designed to be smaller than the width of the base 101 of the front slide block and larger than the width of the groove on the slide rail 30, so that the up-and-down movement is limited, and the structural weight is reduced as much as possible.
Fig. 3c is a side view of the front slider of the connection structure of the unmanned aerial vehicle ejection system according to the embodiment of the disclosure. As shown in fig. 3c, from the side, preceding slider adopts approximate right triangle design, and preceding slider base 101 sets up on last right-angle side, and baffle 103 sets up on this relative summit of right-angle side under the preceding slider, designs into slope form (the hypotenuse of right triangle promptly) with the leading edge, when reducing unmanned aerial vehicle aerodynamic drag, also lightens unmanned aerial vehicle weight.
Meanwhile, the front slider 10 has rounded corners formed at four positions. Set up the radius angle at preceding slider base 101 front end and with preceding slider longitudinal baffle 102 junction, and the front end of baffle 103 sets up the radius angle under the slider in the front, can reduce the slider when flight because of the resistance that the windward produced, preceding slider base 101 rear end sets up the radius angle with slide rail 30 contact position, and the rear end of baffle 103 sets up the radius angle with slide rail 30 contact position under the slider in the front, the variable point contact is the face contact when can making the slider lie in the slide rail separation, reduce the damage to slide rail and slider self that produces because of the extrusion when leaving the rail.
The front slider 10 is further provided with a front slider counter bore 104 for connecting with an unmanned aerial vehicle. Fig. 3d is a bottom view of the front slider of the connection structure of the unmanned aerial vehicle ejection system according to the embodiment of the disclosure. As shown in fig. 3d, two front slider counter bores 104 are formed in the front slider base 101, and the two front slider counter bores 104 in the transverse parallel design are used for fixedly connecting the slider to the wing. Considering that there is a lower stop at the rear of the slide 20, it is not easy to mill holes, so a countersunk hole can be arranged at the leading edge. As can also be seen in fig. 3d, the width of the front slider lower stop plate 103 is smaller than the front slider base 101 and larger than the front slider lower stop plate 103.
Fig. 4a is a schematic perspective structure view of a rear slider of a connection structure of an unmanned aerial vehicle ejection system according to an embodiment of the present disclosure. As shown in fig. 4a, the rear slider 20 includes a rear slider base 201, a rear slider longitudinal partition 202 and a rear slider lower baffle 203. The rear sliding block longitudinal partition plate 202 is perpendicular to the rear sliding block base 201, and the rear sliding block lower baffle plate 203 is arranged on one side far away from the rear sliding block base 201.
Fig. 4b is a front view of the rear slider of the connecting structure of the unmanned aerial vehicle ejection system according to the embodiment of the disclosure. As shown in fig. 4b, the whole rear slider 20 also adopts an i-shaped structure, and the upper rear slider base 201 and the lower rear slider lower baffle 203 are used for limiting the slide rail in the vertical direction, so that the unmanned aerial vehicle is prevented from moving in the vertical direction in the installation process of the ejection rack and the ejection process of the unmanned aerial vehicle. The rear slider longitudinal partition plate 202 between the rear slider base 201 and the rear slider lower baffle plate 203 can be inserted into the groove of the sliding groove 30 to slide, and the distance between the rear slider base 201 and the rear slider lower baffle plate 203 is equal to the thickness of the partition plate on the sliding rail 30. In some embodiments, the pitch angle of the airplane may become larger during the ejection process, the lift force may increase due to acceleration during the ejection process of the airplane, and when the lift force is greater than the weight of the airplane body, the lower baffle of the slider will abut against the lower surface of the upper baffle of the slide rail, so the distance between the rear slider base 201 and the lower baffle 203 of the rear slider may be set to be 2mm to 5mm greater than the thickness of the upper baffle of the slide rail 30.
Fig. 4c is a rear slider side view of a connection structure of an unmanned aerial vehicle ejection system according to an embodiment of the disclosure. As shown in fig. 4c, the rear slider 20 is in an approximately rectangular layout when viewed from the side, and since the upper surfaces of the rear slider 20 and the front slider 10 are fixed on the wings of the unmanned aerial vehicle, that is, the upper surfaces of the rear slider 20 and the front slider 10 are in the same horizontal plane, the overall thickness d2 of the rear slider 20 is set to be less than or equal to the thickness d1 of the front slider base 101, so that the lowest position of the rear slider 20 is ensured not to contact with the slide rail 30. The front end and the rear end of the rear sliding block base 201 and the tail end of the rear sliding block lower baffle 203 are designed to be chamfered, so that the sliding block is prevented from being scratched and damaged due to extrusion when the sliding block is separated from a sliding rail.
Fig. 4d is a bottom view of the rear slider of the connection structure of the unmanned aerial vehicle ejection system according to the embodiment of the disclosure. As shown in fig. 4d, different from the front slider 10, the rear slider counter bore 204 used for being fixedly connected with the unmanned aerial vehicle on the rear slider 20 adopts a tandem double-bore layout perpendicular to the front edge of the unmanned aerial vehicle, and the layout of the counter bore is different because the front part of the slide rail is low and the rear part of the slide rail is high, so that the front slider longitudinal partition is designed to be high, the rear slider longitudinal partition is short, the thrust acting areas of the front slider and the rear slider are required to be approximately equal, so that the front slider longitudinal partition which is high is narrow, and the rear slider longitudinal partition which is short is wide. The front sliding block longitudinal partition plate is designed to be narrower and higher, so that the weight is reduced, the thickness of the plate wall is possibly smaller than the aperture of the counter bore, and the front sliding block longitudinal partition plate is arranged on two sides of the partition plate in a transverse arrangement mode; the longitudinal partition plate of the rear sliding block is designed to be wider and shorter, and can adopt a longitudinal arrangement or a transverse arrangement arranged at two sides of the partition plate.
