Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV take-off assistance platform and an obstacle avoidance UAV. Background Technology

[0002] With the continuous development of drone technology, its application in various fields such as agriculture, aerial photography, inspection, logistics, and emergency rescue is becoming increasingly widespread. However, in complex terrain or long-distance operation scenarios, the takeoff conditions of drones are often limited. Traditional manual ground takeoff methods are not only inconvenient to operate but also pose certain safety hazards, making it difficult to meet the requirements for efficient and stable takeoff and landing. To address this, in recent years, some auxiliary takeoff platforms have been gradually developed to provide a stable and reliable takeoff foundation for drones.

[0003] Currently, most commercially available drone takeoff assistance platforms are fixed structures, lacking flexible mobility and altitude adjustment capabilities. This makes them unsuitable for mounting equipment at different heights or locations, such as vehicles, ships, or other mobile carriers. Furthermore, existing platforms typically lack effective limiting and securing devices, making them prone to drone drifting or even slipping during transport due to vibration or external forces, affecting flight safety and operational reliability. Simultaneously, the platform's simple structure and low functional integration limit its practical application in complex environments. Utility Model Content

[0004] To achieve the above objectives, this application provides a drone takeoff assistance platform, including a base pole and a movable wheel installed at the lower end of the base pole. A push rod is welded to one end of the base pole, and a sliding member is movably installed on the push rod. A lifting plate is fixedly connected to one side of the sliding member, and a takeoff platform assembly is slidably installed on the lifting plate. The takeoff platform assembly can adjust its height as the sliding member slides, and can slide to a position close to the mobile device to facilitate the installation of the takeoff platform assembly on the mobile device.

[0005] Preferably, a cylinder is installed on one side of the bottom rod, the piston end of the cylinder is fixedly connected to the upper end of the connecting rod, and the lower end of the connecting rod is fixedly connected to the sliding member.

[0006] Preferably, the takeoff platform assembly includes a bottom frame, which slides on a guide rail one mounted on the upper side of the lifting plate, and a landing plate is provided at the upper end of the bottom frame. The landing plate slides with the bottom frame through a guide rail two.

[0007] Preferably, the guide rail has a first insertion hole, and the bottom frame has a second insertion hole, with the pin passing through the second insertion hole and engaging with the first insertion hole.

[0008] Preferably, a symmetrical sliding groove is provided on one side of the bottom frame, and a limit rod is slidably arranged in the sliding groove. The limit rod is used to limit the landing plate.

[0009] Preferably, a lead screw is rotatably mounted on one side of the slide groove, and one side of the limiting rod passes through the side wall of the slide groove and is threadedly connected to the lead screw.

[0010] Preferably, positioning sleeves are hinged to both sides of the bottom frame, and bolts are provided at the lower end of the positioning sleeves.

[0011] Preferably, the upper surface of the landing plate is symmetrically provided with two grooves, within which a limit plate is slidably disposed.

[0012] Preferably, a lead screw is rotatably installed inside the second slide groove, and the lead screw is threadedly connected to the bottom of the limiting plate.

[0013] Preferably, in another aspect, this application also provides an obstacle avoidance drone, including any of the drone takeoff assistance platforms described above, including a drone body, wherein a camera is installed at the lower end of the drone body.

[0014] This utility model provides a drone takeoff assistance platform and obstacle avoidance drone, which, compared with the prior art:

[0015] 1. This utility model, by incorporating a base pole, a push rod, and movable wheels mounted at the lower end of the base pole, enables the entire takeoff assistance platform to possess excellent mobility, facilitating the movement of the drone itself to the target work area.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1 to 8 This utility model provides a drone takeoff assistance platform and obstacle avoidance drone, including a base pole 1. Multiple casters are mounted on the lower end of the base pole 1, giving the entire device good mobility and facilitating the transport of the drone to the target work area. A push rod 2 is welded and fixed to one end of the base pole 1, allowing the user to push the entire device. A sliding member 3 is movably mounted on the push rod 2, and a lifting plate 4 is fixedly connected to one side of the sliding member 3. The sliding member 3 drives the lifting plate 4 to slide up and down along the push rod 2, thereby realizing the height adjustment function of the takeoff platform component.

[0030] Furthermore, a cylinder 5 is provided on one side of the base rod 1. The piston rod end of the cylinder 5 is fixedly connected to the upper end of the connecting rod 6, and the lower end of the connecting rod 6 is fixedly connected to the sliding member 3. By controlling the extension and retraction of the cylinder 5, the sliding member 3 can be driven to slide up and down on the push rod 2, thereby driving the lifting plate 4 to adjust its height, realizing automated operation and improving ease of use and efficiency.

[0031] A takeoff platform component is slidably mounted on the lifting platform 4. The takeoff platform component can slide laterally along the lifting platform 4 and adjust its position as needed to bring it close to the mobile device to be mounted, so as to stably install the takeoff platform component on the mobile device.

[0032] The takeoff platform assembly mainly includes a bottom frame 10, which is slidably mounted on a guide rail 7 installed on top of the lifting plate 4, allowing its position to be adjusted by sliding back and forth on the guide rail 7. A landing plate 12 is located above the bottom frame 10, and the landing plate 12 slides into the bottom frame 10 via a guide rail 11, allowing it to be adjusted horizontally. Sliding the landing plate 12 outwards further facilitates the takeoff of the UAV.

[0033] In addition, a first insertion hole 8 is provided on the guide rail 7, and a second insertion hole 13 is provided on the bottom of the bottom frame 10. The pin 9 passes through the second insertion hole 13 and is inserted into the first insertion hole 8, which can improve the stability of the bottom frame 10.

[0034] To improve the connection stability between the takeoff platform assembly and the mobile device, positioning sleeves 17 are hinged to both sides of the bottom frame 10. The lower end of the positioning sleeve 17 is provided with bolts 18. By tightening the bolts 18, the entire takeoff platform assembly can be firmly fixed to the mobile device to prevent it from shifting during transportation.

[0035] In addition, symmetrically arranged slide grooves 14 are provided on one side of the bottom frame 10. Each slide groove 14 is slidably provided with a limit rod 15 to limit the landing plate 12 and prevent it from sliding arbitrarily when not in operation.

[0036] A lead screw 16 is rotatably mounted on one side of the slide groove 14, and one side of the limiting rod 15 passes through the side wall of the slide groove 14 and is threadedly connected to the lead screw 16. By rotating the lead screw 16, the position of the limiting rod 15 can be precisely adjusted to effectively lock the lifting plate 12.

[0037] To further enhance the fixation capability of the UAV body 22, a second groove 19 is symmetrically formed on the upper surface of the landing plate 12, and a limit plate 21 is slidably disposed within the second groove 19. A second lead screw 20 is also rotatably installed within the second groove 19, and the second lead screw 20 is threadedly connected to the bottom of the limit plate 21. By rotating the second lead screw 20, the limit plate 21 can be driven to move towards the center or open outward, thereby adapting to UAV landing gear of different sizes and firmly fixing them to prevent the UAV body 22 from shifting or falling off due to vibration or impact during movement.

[0038] On the other hand, this application also provides an obstacle avoidance drone, including a drone take-off assistance platform comprising any one of the above, including a drone body 22, with a camera 23 installed at the lower end of the drone body 22 for collecting ground image information, realizing real-time monitoring of the surrounding environment and obstacle recognition, and improving the drone's autonomous take-off and obstacle avoidance capabilities in complex terrain.

[0039] In summary, the working principle of the UAV takeoff assistance platform and obstacle avoidance UAV of this utility model embodiment is as follows: In use, the entire device is first pushed to the target work area by the movable wheels installed at the lower end of the base rod 1, and the operator holds the push rod 2 to move it; secondly, the cylinder 5 can be controlled to work according to the height requirements of the mounted equipment, and its piston rod drives the sliding part 3 to slide up and down along the push rod 2 through the connecting rod 6, thereby driving the lifting plate 4 and the takeoff platform assembly fixed thereon to achieve height adjustment;

[0040] After the takeoff platform assembly is adjusted to a suitable height, it is slid laterally along guide rail 7 to a position close to the mobile device. The entire platform is then securely installed on the mobile device using the positioning sleeves 17 and bolts 18 on both sides of the bottom frame 10. Next, according to the landing gear size of the UAV body 22, the screw 20 is rotated to drive the limiting plate 21 to slide within the slide groove 19, moving towards the center to fix the UAV landing gear and achieve a firm fixation of the UAV body 22. At the same time, in the non-working state, the limiting rod 15 is slid within the slide groove 14 by rotating the screw 16 to limit and lock the landing plate 12, preventing it from shifting due to vibration. Before the UAV takes off, the landing plate 12 can be slid outward along guide rail 11 to provide the UAV with a wider takeoff space.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
