Description

Technical Field

[0001] This utility model relates to the field of launching device technology, and in particular to a drone launcher. Background Technology

[0002] Currently, drone launch methods can be categorized as follows: runway takeoff, catapult launch, rocket-assisted launch, hand-launched launch, airdrop, and vertical takeoff. In rocket-assisted launch, the drone's kinetic energy for takeoff comes from the energy generated by the combustion of fuel in the rocket booster. The advantages of rocket-assisted launch include a smaller footprint, lower cost, less susceptibility to external influences, and faster deployment.

[0021] The rocket support assembly provides stability to the rocket, thereby increasing the stability of the drone support before launch. By moving the lever, the rotating frame can be rotated, causing the support plate to align with the rocket, thus improving the stability of the rocket support and consequently, the drone support.

[0041] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0042] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0043] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0047] like Figures 1 to 8As shown, this utility model provides a drone launcher, including: a pitch angle adjustment assembly 1, including a base bracket 11; a front support assembly 2, including a front support rod 21, a support block 22, and a support rod 23, the top of the front support rod 21 is provided with a groove 24, the support rod 23 is disposed on the support block 22 and placed in the groove 24, the bottom of the front support rod 21 is rotatably connected to the base bracket 11, and the support block 22 is used to fixally connect to the drone 6; a rear support assembly 3, including a rear support rod 31, a slide rail 32, and a slider 33, the top of the rear support rod 31 is provided with a slide rail 32, the slider 33 is slidably disposed along the length direction of the slide rail 32, the bottom of the support rod is fixedly connected to the base bracket 11, and the slider 33 is used to fixally connect to the drone 6 so as to move along the slide rail 32 when the drone 6 is launched.

[0048] When using the drone launcher provided in this embodiment, the front connection point of the drone 6 can be connected to the front support component 2, and the tail connection point of the drone 6 can be connected to the rear support component 3.

[0049] Specifically, the support block 22 is connected and fixed to the front connection point of the drone 6. The front support rod 21 is rotated to a suitable position so that the support rod 23 can be placed in the slot 24. The support rod 23 and the slot 24 are connected by a shaft and a hole. The support rod 23 can rotate relative to the slot 24. Since the front support rod 21 can rotate relative to the bottom bracket 11, the position of the slot 24 can be adjusted by adjusting the position of the front support rod 21. Adjusting the position of the support rod 23 relative to the slot 24 can make the support rod 23 and the slot 24 fit together. Compared with the traditional launcher and the drone 6 which are not movable, the front support component 2 provided in this embodiment can be adjusted according to the specific situation of the drone 6, so that the connection between the drone launcher and the drone 6 fits better, which can avoid the support point being suspended and make the drone 6 more stable before launch.

[0050] The slider 33 is connected and fixed to the tail of the drone 6. The slider 33 is connected to the slide rail 32, which can support the drone 6 before launch and work with the front support component 2 to ensure the stability of the drone 6. Moreover, the slider 33 can slide along the slide rail 32, so the slide rail 32 can limit the movement of the slider 33 as it follows the launch of the drone 6, so that the movement stability of the slider 33 is good, thereby improving the stability of the drone 6 during launch.

[0051] The pitch angle adjustment component 1 can be used to adjust the drone 6 to a suitable launch angle.

[0052] Therefore, the flexible arrangement of the front support component 2 in the drone launcher provided in this embodiment allows the connection between the drone launcher and the drone 6 to fit more closely, thereby improving the stability of the drone launcher's support for the drone 6. The rear support component 3 can not only cooperate with the front support component 2 to provide stable support for the drone 6 before launch, but also improve the stability of the drone 6 during launch.

[0053] The bracket 24 can be directly provided on the top of the front support rod 21, or the bracket 29 can be fixed on the top of the front support rod 21, and the bracket 24 can be provided on the bracket 29.

[0054] like Figures 1 to 3 As shown, based on the above embodiment, the pitch angle adjustment assembly 1 further includes a base frame 12, a support leg 13, a skid plate 14, and a second telescopic member 15; one end of the base bracket 11 is rotatably connected to the base frame 12, and the other end is rotatably connected to one end of the support leg 13, the other end of the support leg 13 is rotatably connected to the skid plate 14, and the second telescopic member 15 is connected between the base bracket 11 and the support leg 13.

[0055] In this embodiment, the base frame 12 can be fixed (e.g., fixed to a support surface) to adjust the overall angle of the second telescopic member 15. During the adjustment of the length of the second telescopic member 15, the skid plate 14 slides on the support surface (e.g., the ground or platform surface), thereby changing the angle of the base bracket 11 relative to the outrigger 13, and further changing the angle of the base bracket 11 relative to the support surface. The base bracket 11 drives the UAV 6 to reach the required launch angle. The pitch angle adjustment component 1 provided in this embodiment has a simple structure and good support stability.

[0056] Optionally, after the drone 6 is positioned on the drone launcher, the drone 6 is parallel to the base bracket 11 (parallelism here means roughly parallel, not just absolutely parallel, and some error is allowed). In this way, the drone 6 can be placed at the required launch angle simply by adjusting the base bracket 11, which is convenient for operation.

[0057] The second telescopic component 15 can be a linear motor, an electric telescopic rod, or the like. Optionally, the second telescopic component 15 can be a telescopic rod with a double-ended stud structure, which is convenient for adjustment and has good stability.

[0058] Specifically, the bottom of the support block 22 has oppositely arranged lugs, and the two ends of the support rod 23 are respectively connected to the two lugs. There is a gap between the support rod 23 and the support block 22, which makes it easier for the support rod 23 to be placed in the support groove 24 and to rotate within the support groove 24.

[0059] like Figures 1 to 5As shown, based on the above embodiment, the front support assembly 2 further includes a first telescopic member 25 and a connecting block 26. The bottom of the first telescopic member 25 is rotatably connected to the base bracket 11, and the top of the first telescopic member 25 is detachably connected to the connecting block 26. The connecting block 26 is used to fix the connection to the drone 6.

[0060] In this embodiment, the connecting block 26 is fixed to the drone 6. Based on the position of the drone 6, the first telescopic member 25 is rotated to a suitable position, and its overall length is adjusted to connect it to the connecting block 26. The front support rod 21, support block 22, support groove 24, support rod 23, and support block 22 provide support for the front of the drone 6. The first telescopic member 25 and connecting block 26 provide a second positioning and support for the drone 6, further improving its stability. When the drone 6 is launched, the first telescopic member 25 can be disconnected from the connecting block 26.

[0061] There are several ways to detachably connect the first telescopic member 25 and the connecting block 26, such as by using a buckle to detachably connect the first telescopic member 25 and the connecting block 26.

[0062] As an alternative, such as Figure 4 As shown, the bottom of the connecting block 26 has a connecting ear, and the connecting ear has a connecting hole. The top of the first telescopic member 25 has a U-shaped groove, and the opposite sidewalls of the U-shaped groove have corresponding mating holes. The connecting ear is inserted into the U-shaped groove, and the mating hole and the connecting hole are provided with the same connecting pin 27.

[0063] In this embodiment, one end of the connecting pin 27 is passed through a mating hole, a connecting hole and another mating hole in sequence to connect the first telescopic member 25 and the connecting block 26, which can realize quick disassembly of the block and facilitate operation.

[0064] The first telescopic component 25 can be a linear motor, an electric telescopic rod, or the like. Optionally, the first telescopic component 25 can be a telescopic rod with a double-ended stud structure, which is convenient for adjustment and has good stability.

[0065] like Figure 1 and Figure 3 As shown, based on the above embodiment, a first elastic member 28 is further provided between the front support rod and the bottom bracket 11, and the first elastic member 28 has the tendency to press the front support rod towards the bottom bracket 11.

[0066] In this embodiment, when the drone 6 is launched, the support rod 23 disengages from the support slot 24, the first telescopic member 25 disengages from the connecting block 26, and the first elastic member 28 can drive the front support rod to move towards the base bracket 11 (i.e., downwards), thereby further ensuring that the movement of the drone 6 is not affected. Preferably, the first elastic member 28 drives the front support rod to rotate from the front (the launch direction of the drone) towards the base bracket 11.

[0067] The first elastic element 28 can be a bar spring (compression spring or tension spring), which is directly connected between the base bracket 11 and the front support rod 21. Optionally, the first elastic element 28 can be a first torsion spring, with the front support rod 21 rotatably connected to the base bracket 11 via a first shaft. The first torsion spring is sleeved on the first shaft, resulting in a compact structure and minimal space occupation. It can be understood that the two ends of the first torsion spring are respectively connected to the base bracket 11 and the front support rod 21.

[0068] like Figure 1 and Figure 3 As shown, based on the above embodiment, a second elastic member 210 is further provided between the first telescopic member 25 and the bottom bracket 11. The second elastic member 210 has the tendency to press the front support rod towards the bottom bracket 11.

[0069] In this embodiment, when the drone 6 is launched, the support rod 23 disengages from the slot 24, the first telescopic member 25 disengages from the connecting block 26, and the second elastic member 210 can drive the first telescopic member 25 to move towards the base bracket 11 (i.e., downwards), thereby further ensuring that the movement of the drone 6 is not affected. Preferably, the second elastic member 210 drives the first telescopic member to rotate from the front (the launch direction of the drone) towards the base bracket 11.

[0070] The second elastic element 210 can be a bar spring (compression spring or tension spring), which is directly connected between the base bracket 11 and the first telescopic member 25. Optionally, the second elastic element 210 can be a second torsion spring, with the first telescopic member 25 rotatably connected to the base bracket 11 via a second shaft. The second torsion spring is sleeved on the second shaft, resulting in a compact structure and minimal space occupation. It can be understood that the two ends of the second torsion spring are respectively connected to the base bracket 11 and the first telescopic member.

[0071] As an optional solution, there are two front support rods 21, which are symmetrically arranged in the width direction of the base bracket 11. That is, the two front support rods 21 are symmetrically arranged on the left and right sides of the UAV 6. Correspondingly, the support block 22, support rod 23, and support groove 24 are also symmetrically arranged.

[0072] like Figure 6 and Figure 7As shown, based on the above embodiment, the slide rail 32 further includes a base and a slide groove 321 disposed on the base (the length direction of the slide groove 321 is consistent with the length direction of the base bracket 11, that is, parallel to the launch movement direction of the UAV 6), the slide groove 321 has an opening on the side, and the base is connected to the rear support rod 31; the slider 33 includes a slide plate 331 and a slide column 332 connected to the slide plate 331, the slide column 332 is slidably disposed along the slide groove 321, the slide plate 331 is used to connect with the UAV 6, and the base is connected to the rear support rod 31; the slider 33 includes a slide plate 331 and a slide column 332 connected to the slide plate 331, the slide column 332 is slidably disposed along the slide groove 321, and the slide plate 331 is used to connect with the UAV 6.

[0073] In this embodiment, the slide plate 331 is fixedly connected to the drone 6, and the slide column 332 extends into the slide groove 321 through the opening of the slide groove 321. It can move in the slide groove 321 with the drone 6 when it is launched. This slide rail 32 has a simple structure and is easy to install.

[0074] like Figure 6 and Figure 7 As shown, based on the above embodiment, the rear support assembly further includes a first lateral adjustment member, a second lateral adjustment member, and a vertical adjustment member; the base includes a base block 322 and a movable plate 323, the slider 33 has a groove to form a sliding groove 321, the movable plate 323 is slidably disposed on the base block 322 along the length direction of the sliding groove 321 and is fixed relative to the base block 322 by the first lateral adjustment member; the base block 322 is slidably disposed on the vertical adjustment member along a direction perpendicular to the length direction of the sliding groove 321 and is fixed relative to the vertical adjustment member by the second lateral adjustment member; the vertical adjustment member is connected to the rear support rod 31.

[0075] In this embodiment, the slider 33 is moved, thereby adjusting its position along the length of the slide groove 321, and thus adjusting the position of the slide groove 321 in the first lateral direction. The position of the slider 33 can be fixed by the first lateral adjustment member. The base block 322 is moved, thereby adjusting its position in the direction perpendicular to the length of the slide groove 321, and thus adjusting the position of the slide groove 321 in the second lateral direction. The position of the base block 322 can be fixed by the second lateral adjustment member. The vertical adjustment member can adjust the vertical position of the base block 322, thereby adjusting the position of the slide groove 321 in the vertical direction. That is, in this embodiment, the position of the slide groove 321 can be adjusted on the XYZ three axes, so that the slide groove 321 can more accurately and closely fit the slide column 332, thereby making the connection between the UAV launcher and the UAV 6 more stable and further improving the stability of the UAV 6.

[0076] Specifically, a protrusion is formed on the base block 322, and a strip groove is opened on one side of the protrusion in a direction perpendicular to the length direction of the slide groove 321. The slider 33 is generally arranged in a "C" shape, and the bottom of the slider 33 slides in the strip groove.

[0077] The first lateral adjustment component, the second lateral adjustment component, and the vertical adjustment component can all adopt telescopic structures such as screw and nut mechanisms.

[0078] As an alternative, such as Figure 6 and Figure 7 As shown, the vertical adjustment component includes a first adjustment platform 34 and a second adjustment platform 35; one side of the first adjustment platform 34 (e.g., as shown) Figure 6 The lower side (as shown) is connected to the rear support rod 31, and the other side is provided with a first inclined surface (for example, as shown). Figure 6 As shown above, the first inclined surface is provided with a plurality of first locking teeth 36 spaced apart along the extension direction of the first inclined surface; one side of the second adjusting platform 35 is connected to the base, and the other side is provided with a second inclined surface that cooperates with the first inclined surface. The second inclined surface is provided with a plurality of second locking teeth 37 spaced apart along the extension direction of the second inclined surface, and the first locking teeth 36 and the second locking teeth 37 mesh with each other.

[0079] In this embodiment, the first adjusting platform 34 and the second adjusting platform 35 can be engaged together by the engagement of the first caliper and the second caliper to achieve unidirectional positioning. Different parts of the first adjusting platform 34 engage with the second adjusting platform 35, resulting in different overall heights of the first adjusting platform 34 and the second adjusting platform 35. This allows for adjustment of the slide groove 321 along the Z-axis. This vertical adjusting component has a simple structure and is easy to install.

[0080] Optionally, the first inclined surface and the second inclined surface are inclined relative to the length direction of the slide 321. That is, in the direction of movement of the UAV 6, the first inclined surface and the second inclined surface are engaged together, which can prevent the first adjustment platform 34 and the second adjustment platform 35 from separating under the impact of the launch of the UAV 6.

[0081] As an alternative, such as Figure 6 and Figure 7 As shown, the first lateral adjustment component includes a first fastener 38, the side wall of the slider 33 is provided with a first strip hole extending along the length direction of the slide groove 321, the base block 322 is provided with a first fastening hole, and the first fastener 38 passes through the first strip hole and is connected to the first fastening hole; the second lateral adjustment component includes a second fastener 39, the base block 322 is provided with a second strip hole extending along the direction perpendicular to the length direction of the slide groove 321, the vertical adjustment component (which may be the first adjustment platform 34) is provided with a second fastening hole, and the second fastener 39 passes through the second strip hole and is connected to the second fastening hole.

[0082] In this embodiment, when it is necessary to adjust the position of the slide 321 in the first lateral direction, loosen the first fastener 38 (e.g., a bolt), move the slider 33 to the appropriate position, and then tighten the first fastener 38 again. When it is necessary to adjust the position of the slide 321 in the second lateral direction, loosen the second fastener 39 (e.g., a bolt), move the base block 322 to the appropriate position, and then tighten the second fastener 39 again. This first and second lateral adjustment mechanism has a simple structure and is easy to operate.

[0083] Specifically, the first adjustment platform 34 is provided with a receiving groove, and the base block 322 is slidably placed in the receiving groove, thereby making the movement process of the base block 322 stable.

[0084] As an alternative, such as Figures 1 to 3 As shown, there are two rear support rods 31, and the two rear supports are symmetrically arranged in the width direction of the base bracket 11. Correspondingly, the slide rail 32 and related structures are also symmetrically arranged.

[0085] like Figures 1 to 3 , Figure 8 As shown, based on any of the above embodiments, the UAV launcher further includes a rocket support assembly 5. The rocket support assembly 5 includes a bracket 51, a rotating frame 52, a support plate 53, a stop bar 54, and a third elastic member 55. The bracket 51 is fixed on the base bracket 11, the rotating frame 52 is rotatably connected to the bracket 51, the support plate 53 is fixed on the rotating frame 52, and the stop bar is slidably disposed on the bracket 51 in the direction facing the rotating frame 52 (that is, the movement of the stop bar 54 can drive the rotating frame 52 to rotate). The third elastic member 55 is connected between the bracket 51 and the rotating frame 52 and can press the rotating frame 52 against the stop bar 54.

[0086] In this embodiment, the rocket support assembly 5 supports the rocket 7, thereby increasing the stability of supporting the UAV 6 before launch. The rotating frame 52 can be rotated by moving the stop lever 54, which in turn rotates the support plate 53 to a position where it is in contact with the rocket 7, thus improving the stability of supporting the rocket 7 and consequently the UAV 6. Regardless of the position of the rotating frame 52, the third elastic element 55 always presses the rotating frame 52 against the stop lever 54 to fix its current position.

[0087] The third elastic element can be a spring (tension spring or compression spring), which is directly connected between the rotating frame and the tail tube bracket. Optionally, the third elastic element is a torsion spring, with the rotating frame rotatably connected to the tail tube bracket via a connecting shaft. The torsion spring is sleeved on the connecting shaft. It can be understood that the two ends of the torsion spring are connected to the rotating frame and the tail tube bracket respectively, and the torsion spring occupies little space.

[0088] Optionally, the support plate 53 is arc-shaped to better fit and support the rocket 7. A baffle is also provided at the rear of the support plate to limit the movement of the rocket's tail end.

[0089] like Figures 1 to 3 , Figure 8 As shown, based on the above embodiment, the rocket support assembly 5 further includes: a third telescopic member 56 (the third telescopic member 56 may be a telescopic rod with a double-headed stud structure), the third telescopic member is connected between the rotating frame 52 and the support plate 53, and the height of the support plate 53 can be adjusted by the third telescopic member 56 so as to better fit the rocket 7.

[0090] like Figures 1 to 3 , Figure 8 As shown, based on the above embodiment, the rocket support assembly 5 further includes an adjusting screw 57, the bracket 51 includes opposing side plates, the rotating frame 52 is rotatably connected between the two side plates, each side plate is provided with a third strip hole, the two ends of the stop rod 54 are respectively slidably disposed in the two third strip holes, the side plate is provided with a through hole in the wall along the length direction of the third strip hole, and the adjusting screw 57 passes through the through hole and abuts against the stop rod 54.

[0091] In this embodiment, the position of the stop lever 54 is adjusted by rotating the adjusting screw 57, thereby adjusting the angle of the rotating frame 52, which facilitates operation.

[0092] A limit rod can be installed on the tailpipe bracket. The limit rod is located on the side of the rotating frame away from the stop bar, thereby limiting the rotation of the rotating frame on the side where the limit rod is located.

[0093] like Figures 1 to 3 As shown, based on the above embodiment, the UAV launcher further includes a flame guide plate 4. The flame guide plate 4 is fixed on the base frame 12 and located at the end of the base bracket 11 away from the support leg 13. The flame guide plate 4 installed at the tail of the base frame 12 facilitates the guidance of the exhaust flame ejected by the rocket 7 when it is launched.
