Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a telescopic UAV launch arm and system. Background Technology

[0002] In recent years, drone technology has been increasingly widely used in logistics, surveying and mapping, agricultural plant protection, emergency rescue, and military reconnaissance. As mission complexity increases, scenarios involving multiple drones working together are becoming more common, which places higher demands on the rapid, efficient, and safe flight of drones.

[0003] Currently, drone launches mostly rely on manual hand-held operation or direct takeoff from fixed platforms. Manual hand-held launches pose personal safety risks and are heavily influenced by the operator's skill and psychological state, resulting in poor launch stability. While fixed-platform launches avoid personal risks, they require significant space. When launching from mobile platforms, vehicle structural limitations (such as the lack of sunroofs or insufficient side windows) often make it difficult to launch drones safely and stably directly from inside the vehicle. Furthermore, when multiple drones are operating collaboratively, dense launches from the same location greatly increase the risk of collisions due to intersecting takeoff paths or airflow interference, leading to low safety.

[0004] Therefore, there is an urgent need in this field for a dedicated device that can solve the above problems and enable automated, safe and reliable flight of drones. Utility Model Content

[0005] In view of the above-mentioned shortcomings or defects in the existing technology, the present invention provides a telescopic drone launch arm, which can flexibly adjust the launch position of the drone to adapt to different scenario requirements.

[0006] To achieve the above objectives, this utility model provides a telescopic drone launch arm, comprising: Mounting base, used as the mounting base for the launching arm; Telescopic boom, including: The first telescopic component is disposed on the mounting base; The second telescopic component is in sliding engagement with the first telescopic component; A placement plate, located at the end of the second telescopic member away from the mounting base, is used to place the drone; A telescopic drive mechanism is disposed on the mounting base and connected to the second telescopic member, used to drive the second telescopic member to slide relative to the first telescopic member.

[0007] Furthermore, the telescopic drive mechanism includes: An elastic element has one end connected to the first telescopic member and the other end connected to the second telescopic member; the elastic element is used to provide a force that causes the second telescopic member to extend relative to the first telescopic member; A flexible traction component, one end of which is connected to the second telescopic component; A drive assembly is fixedly mounted on the mounting base; the drive assembly is connected to the end of the flexible traction member away from the second telescopic member, and is used to control the movement of the second telescopic member relative to the first telescopic member by extending and retracting the flexible traction member.

The flexible traction element is wound around the winch.

[0009] Furthermore, the first telescopic member is an outer sleeve with a sliding cavity formed inside; the second telescopic member is slidably inserted into the first telescopic member.

[0010] Furthermore, the telescopic drive mechanism also includes a limiting component for limiting the sliding stroke of the second telescopic member; the limiting component includes a limiting post, a limiting ring, and a limiting plate; The limiting post is disposed at one end of the second telescopic member close to the first telescopic member and is coaxially disposed with the second telescopic member; the outer diameter of the limiting post is larger than the outer diameter of the second telescopic member and is adapted to the inner diameter of the sliding cavity; The limiting ring is disposed at one end of the first telescopic member near the second telescopic member and is coaxially disposed with the first telescopic member; the inner diameter of the limiting ring is adapted to the outer diameter of the second telescopic member.

[0011] The limiting plate is disposed at one end of the sliding cavity away from the second telescopic member.

[0012] Furthermore, the limiting post is also provided with a spring plunger that protrudes radially along the second telescopic member, and the first telescopic member is provided with a positioning hole that extends radially along the first telescopic member and cooperates with the spring plunger.

[0013] Furthermore, the positioning holes are provided in two places, which are spaced apart along the axial direction of the first telescopic member; The side wall of the spring plunger is also provided with a fixing pin hole, and the axis of the fixing pin hole is perpendicular to the radial direction of the first telescopic member.

[0014] Furthermore, a guide block is provided on the outer periphery of the limiting post, and a guide groove is provided in the sliding cavity that extends axially along the first telescopic member and slides in cooperation with the guide block.

Detailed Implementation

[0021] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] like Figure 1 As shown, this utility model provides a telescopic drone launch arm, including a mounting base 4, a telescopic arm, a placement plate 1, and a telescopic drive mechanism. The mounting base 4 serves as the mounting foundation for the launch arm. The telescopic arm includes: a first telescopic member 3, disposed on the mounting base 4; and a second telescopic member 2, slidably engaged with the first telescopic member 3. The placement plate 1 is disposed at the end of the second telescopic member 2 away from the mounting base 4, and is used to place the drone 8. The telescopic drive mechanism is disposed on the mounting base 4, connected to the second telescopic member 2, and is used to drive the second telescopic member 2 to slide relative to the first telescopic member 3.

[0025] In the above scheme, the telescopic drone launch arm provides a stable mounting base through the mounting base 4, ensuring the stability of the overall structure. The telescopic arm adopts a sliding engagement of the first telescopic component 3 and the second telescopic component 2 to achieve arm length adjustability, thereby adapting to different launch position requirements. The placement plate 1 is used to support the drone 8, and the extension or retraction of the placement plate 1 is achieved by controlling the sliding of the second telescopic component 2 through the telescopic drive assembly. During operation, the telescopic drive assembly drives the second telescopic component 2 to move, changing the position of the placement plate 1 to facilitate the launch of the drone 8.

[0026] The above settings enable flexible adjustment of the launch position of the UAV 8, provide a safe launch distance for the UAV 8, and save space, avoiding the problems of large space occupation and inability to adapt to multiple scenarios that exist with fixed platforms, thereby improving the reliability and adaptability of the UAV 8 launch.

[0027] Understandably, the lengths of the first telescopic component 3 and the second telescopic component 2 can be flexibly adjusted according to actual usage requirements. The first telescopic component 3 and the second telescopic component 2 of the telescopic arm can also be replaced with a multi-section telescopic structure to increase the telescopic range.

[0028] like Figure 2 As shown, in one possible implementation, the telescopic drive mechanism includes: an elastic member 11, one end of which is connected to the first telescopic member 3 and the other end of which is connected to the second telescopic member 2; the elastic member 11 is used to provide a force that causes the second telescopic member 2 to extend relative to the first telescopic member 3; a flexible traction member 9, one end of which is connected to the second telescopic member 2; and a drive assembly, which is fixedly mounted on the mounting base 4; the drive assembly is connected to the end of the flexible traction member 9 away from the second telescopic member 2, and is used to control the movement of the second telescopic member 2 relative to the first telescopic member 3 by extending and retracting the flexible traction member 9.

[0029] The drive assembly includes a winch 6 and a drive motor 10; the winch 6 is rotatably mounted on the mounting base 4 via a rotating shaft; the drive motor 10 is mounted on the mounting base 4 and is connected to the winch 6 in a transmission manner; a flexible traction member 9 is wound around the winch 6.

[0030] In the above scheme, the elastic element 11 continuously provides an elastic force that extends the second telescopic member 2. The drive motor 10 drives the winch 6 to rotate, thereby retracting and extending the flexible traction member 9 wound on the winch 6. When the winch 6 tightens the flexible traction member 9, it overcomes the force of the elastic element 11 and pulls the second telescopic member 2 back; when the winch 6 releases the flexible traction member 9, the force of the elastic element 11 causes the second telescopic member 2 to extend automatically.

[0031] The above settings enable automatic extension and retraction of the telescopic arm, improving operational efficiency. In this embodiment, the drive motor 10 is a servo motor, and the position of the second telescopic member 2 relative to the first telescopic member 3 can be precisely controlled by controlling the rotation angle of the drive motor 10, thereby controlling the takeoff position of the drone 8. In this embodiment, the elastic element 11 is a compression spring, and the flexible traction element 9 is a nylon traction rope.

[0032] In one possible implementation, the first telescopic member 3 is an outer sleeve with a sliding cavity formed inside; the second telescopic member 2 is an inner sleeve that is slidably inserted into the first telescopic member 3. It is understood that the first telescopic member 3 can also be a guide rail, and the second telescopic member 2 can be a slider that slides with the guide rail.

[0033] like Figure 3 and Figure 4 As shown, in one possible implementation, the telescopic drive mechanism further includes a limiting component for limiting the sliding stroke of the second telescopic member 2. The limiting component includes a limiting post 14, a limiting ring 19, and a limiting plate 20. The limiting post 14 is disposed at the end of the second telescopic member 2 near the first telescopic member 3 and is coaxially arranged with the second telescopic member 2. The outer diameter of the limiting post 14 is larger than the outer diameter of the second telescopic member 2 and is adapted to the inner diameter of the sliding cavity. The limiting ring 19 is disposed at the end of the first telescopic member 3 near the second telescopic member 2 and is coaxially arranged with the first telescopic member 3. The inner diameter of the limiting ring 19 is adapted to the outer diameter of the second telescopic member 2. The limiting plate 20 is disposed within the sliding cavity at the end away from the second telescopic member 2.

[0034] In the above scheme, when the second telescopic member 2 extends relative to the first telescopic member 3, the limiting post 14 is restricted by the limiting ring 19 because its outer diameter is larger than the inner diameter of the limiting ring 19, thus limiting the sliding stroke of the second telescopic member 2 during extension. When the second telescopic member 2 retracts relative to the first telescopic member 3, the limiting post 14 is restricted by the limiting plate 20, thus limiting the sliding stroke of the second telescopic member 2 during retraction. This configuration ensures that the telescopic arm operates within a predetermined stroke range, effectively preventing the second telescopic member 2 from accidentally detaching from the first telescopic member 3 and improving reliability.

[0035] Specifically, one end of the elastic element 11 is connected to the surface of the limiting post 14 away from the second telescopic member 2, and the other end is connected to the limiting plate 20. The limiting post 14 and the limiting plate 20 also have through holes for the flexible traction element 9. One end of the flexible traction element 9 is connected to the inner wall of the second telescopic member 2, and the other end passes sequentially through the through hole on the limiting post 14, the sliding cavity in the first telescopic member 3, and the through hole on the limiting plate 20, finally winding around the winch 6.

[0036] In one possible implementation, the limiting post 14 is further provided with a spring plunger 15 that protrudes radially along the second telescopic member 2, and a positioning hole 17 that extends radially along the first telescopic member 3 and engages with the spring plunger 15 is provided through the first telescopic member 3; a sliding groove 18 that extends axially along the first telescopic member 3 and slides with the spring plunger 15 is also provided in the sliding cavity; two positioning holes 17 are provided, which are spaced apart along the axial direction of the first telescopic member 3; a fixing pin hole is also provided on the side wall of the spring plunger 15, and the axis of the fixing pin hole is perpendicular to the radial direction of the first telescopic member 3.

[0037] In the above scheme, the spring plunger 15 protrudes radially and slides along the axial direction of the first telescopic member 3 within the sliding groove 18 along with the second telescopic member 2. When the spring plunger 15 slides to a position aligned with the positioning hole 17, the internal elasticity of the spring plunger 15 causes it to pop out and engage with the positioning hole 17, temporarily locking the second telescopic member 2. The two positioning holes 17 are spaced apart axially, corresponding to the extended and retracted positions of the second telescopic member 2, respectively. The sliding groove 18 guides the movement path of the spring plunger 15, ensuring that the spring plunger 15 can be accurately aligned with the positioning hole 17. After the spring plunger 15 engages with the positioning hole 17, the fixing pin hole can be used to insert a fixing pin to further lock the position of the second telescopic member 2 and prevent accidental loosening.

[0038] The above design enables accurate and flexible positioning of the telescopic arm during extension and retraction, ensuring that the UAV 8 is in the predetermined position. Furthermore, the fixing pin hole provides an additional locking mechanism, further enhancing the reliability of the launch arm.

[0039] Understandably, the spring plunger 15 can be replaced with a ball-head plunger. The number and position distribution of the positioning holes 17 can be flexibly adjusted according to actual needs to adapt to different telescopic position requirements.

[0040] In one possible implementation, a guide block 12 is also provided on the outer periphery of the limiting post 14, and a guide groove is also provided in the sliding cavity, extending axially along the first telescopic member 3 and slidingly engaging with the guide block 12.

[0041] In the above scheme, when the second telescopic member 2 slides within the sliding cavity, the guide block 12 slides with the guide groove, effectively preventing the second telescopic member 2 from rotating circumferentially relative to the first telescopic member 3 within the sliding cavity. This design reduces the swaying and deflection of the telescopic arm during extension and retraction, enhancing the movement stability and reliability of the telescopic arm.

[0042] It is understood that the guide block 12 can be configured as one or more, and the multiple guide blocks 12 can be distributed circumferentially along the limiting post 14. In this embodiment, two guide blocks 12 are configured, and the two guide blocks 12 are symmetrically distributed circumferentially along the limiting post 14.

[0043] like Figure 2 As shown, in one possible implementation, an electromagnet 13 is provided on the placement plate 1, and a magnetic component corresponding to the position of the electromagnet 13 is provided on the bottom of the drone 8.

[0044] In the above scheme, electromagnet 13 is fixedly installed on the surface of the placement plate 1. When energized, it generates a magnetic force, which attracts the magnetic component at the bottom of the drone 8, thus reliably securing the drone 8. When the drone 8 needs to be launched, the power supply to electromagnet 13 is cut off to demagnetize it, the magnetic force disappears, and the drone 8 can take off freely. This design prevents the drone 8 from accidentally falling off the placement plate 1 during the extension of its telescopic arm, improving safety and reliability; it also enables automatic fixing and release of the drone 8, improving launch efficiency.

[0045] It is understandable that the number of electromagnets 13 and their distribution on the placement plate 1 can be flexibly adjusted according to actual needs. In this embodiment, four electromagnets 13 are used.

[0046] In one possible implementation, the mounting base 4 is further provided with several sets of fixing rings 7. The fixing rings 7 are sleeved on the outer circumferential surface of the first telescopic member 3 and are fixedly connected to the mounting base 4 by bolts. Through the above arrangement, the first telescopic member 3 can be firmly fixed on the mounting base 4, improving safety and reliability.

[0047] This utility model also provides a drone launch system, including a support base and multiple telescopic drone launch arms. The mounting base 4 of each telescopic drone launch arm is fixedly mounted on the support base. The extension directions of the telescopic arms are radial or parallel to each other. The support base can be a fixed platform or a mobile vehicle. Through this configuration, the system reduces mutual interference when multiple drones take off, improves the safety and reliability of multi-drone launches, and is suitable for large-scale, clustered drone operations.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0049] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0050] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
