Description

Technical Field

[0001] This utility model relates to the field of unmanned helicopter technology, specifically to an emergency rescue unmanned helicopter that facilitates the delivery of supplies. Background Technology

[0002] As a typical form of unmanned aerial vehicle, unmanned helicopters have the functions of vertical take-off and landing, hovering in the air, and flexible flight. They also have the characteristics of large loading capacity, long endurance, strong maneuverability and small take-off and landing space. They can perform various tasks such as reconnaissance, monitoring and emergency rescue without being affected by terrain and take-off and landing conditions. They are especially suitable for transportation and delivery missions in complex environments such as plateaus and islands and have extremely high economic value and strategic significance.

[0003] For example, utility model patent CN203623966U discloses a cargo delivery device for unmanned helicopters, including a support frame, a spherical container, and a ring-shaped bracket. The key feature is that the top of the support frame is fixedly connected to the belly of the unmanned helicopter, and the lower part is equipped with a small shaft and a travel monitoring device for the ring-shaped bracket. One end of the small shaft is connected to the ring-shaped bracket, and the other end is connected to an electrical control system via a coupling. The spherical container is mounted on the ring-shaped bracket. By installing the cargo delivery device on the belly of the unmanned helicopter, and controlling it via the unmanned helicopter's computer system or a remote computer, the unmanned helicopter, which was previously unable to transport cargo, can now load, transport, and deliver cargo. This cargo delivery device can be used for military purposes, such as launching offensive weapons at the enemy, or for civilian purposes, such as disaster relief, transporting emergency supplies and medicines. Therefore, it has broad application prospects. However, the spherical container placed on the ring bracket may interfere with objects in the external environment during movement, causing instability on the ring bracket and resulting in shaking. Ultimately, the spherical container may fall off the ring bracket. To address this, we propose an emergency rescue unmanned helicopter that facilitates cargo delivery. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an emergency rescue unmanned helicopter that facilitates the deployment of supplies, including a helicopter body 1, a propeller 2 and a stabilizer 3.

A material blocking component 49 is provided at the front end of the material receiving and dispensing plate 48.

[0025] Specifically, when collecting materials, stepper motor 42 can be activated. The output of stepper motor 42 drives rotating shaft 43 to rotate counterclockwise. At this time, rotating shaft 43 drives material placement box 44 to adjust its angle counterclockwise. Rotating shaft 43 also drives gear 46 to adjust its angle counterclockwise. At this time, gear 46 drives rack 411 to move forward. Rack 411 drives L-shaped fixing plate 410 and slide bar 47 to move. Slide bar 47 slides on the inner wall of slide groove 45. At this time, slide bar 47 drives material collection plate 48 to move outward. During this process, material collection plate 48... When material placement box 44 slides relative to material placement box 8, the blocking plate moves material blocking component 49 forward. Material placement plate 48 moves guide post 413 and limit plate 414. Guide post 413 slides relative to material placement box 44. Material can then be placed on top of material placement plate 48. Stepper motor 42 is then started again. Stepper motor 42 reverses its output. Stepper motor 42 reverses its output. Rotating shaft 43 reverses its output. Rotating shaft 43 reverses its output. Material placement box 44 reverses its output. During this process, material placement plate 48 returns material to its original position.

[0026] In this embodiment, the material blocking assembly 49 includes a material blocking plate 491. A placement groove 492 is provided on the lower front side of the material blocking plate 491. A follower shaft 493 is rotatably connected between the inner walls of the placement groove 492 through a bearing. A contact wheel 494 is fixedly installed at the middle of the outer end of the follower shaft 493.

[0027] Specifically, the material blocking component 49 can perform front-end blocking and limiting actions on materials, and can prevent the material blocking plate 491 from making hard contact with the ground during the material loading and unloading process, thereby reducing the wear of the material blocking plate 491.

[0028] In this embodiment, the rotating shaft 43 passes through the gear 46, and both gears 46 are located on the outside of the material placement box 44.

[0029] Specifically, ensure that gear 46 does not interfere with material placement box 44 during rotation.

[0030] In this embodiment, the rotating shaft 43 passes through the left side of the C-shaped plate 41, and the end of the rotating shaft 43 away from the stepper motor 42 is rotatably connected to the C-shaped plate 41 through a bearing.

[0031] Specifically, ensure that the rotating shaft 43 does not interfere with the C-shaped plate 41 during rotation.

[0032] In this embodiment, a guide post 413 is fixedly installed at the rear end of the material receiving and dispensing plate 48. The guide post 413 passes through the material placement box 44, and the outer end of the guide post 413 is slidably connected to the material placement box 44.

[0033] Specifically, the guide post 413 can improve the stability of the material receiving and discharging plate 48 during movement.

[0034] In this embodiment, a limiting circular plate 414 is fixedly installed at the rear end of the guide post 413, and the outer diameter of the limiting circular plate 414 is larger than the outer diameter of the guide post 413.

[0035] Specifically, the limiting circular plate 414 can be used to limit the maximum forward displacement of the material receiving and discharging plate 48.

[0036] In this embodiment, the lower end of the material receiving and dispensing plate 48 is slidably connected to the material placement box 44, and two symmetrically arranged rear baffles 412 are fixedly installed on the inner rear end of the material placement box 44.

[0037] Specifically, ensure that the material receiving and dispensing plate 48 does not interfere with the material placement box 44 during the sliding process.

[0038] In this embodiment, a plurality of circumferentially distributed propellers 2 are provided on the upper end of the helicopter body 1, and a stabilizing propeller 3 is provided on one side of the rear end of the helicopter body 1.

[0039] Specifically, the helicopter body 1 can be lifted and lowered by the propeller 2 and the stabilizer 3.

[0040] Working principle: When collecting materials, stepper motor 42 is activated. The output of stepper motor 42 drives rotating shaft 43 to rotate counterclockwise. Rotating shaft 43 then drives material placement box 44 to adjust its angle counterclockwise. Simultaneously, rotating shaft 43 drives gear 46 to adjust its angle counterclockwise. Gear 46 then drives rack 411 to move forward. Rack 411 moves L-shaped fixing plate 410 and slide bar 47. Slide bar 47 slides on the inner wall of slide groove 45. Slide bar 47 then drives material receiving plate 48 to move outward. During this process, material receiving plate 48 slides relative to material placement box 44. The blocking plate 48 moves the material blocking component 49 forward, and the material blocking plate 48 moves the guide post 413 and the limiting circular plate 414. The guide post 413 slides against the material placement box 44. The material can then be placed on the upper part of the material blocking plate 48. Next, the stepper motor 42 is started again, and the output of the stepper motor 42 reverses. The output of the stepper motor 42 drives the rotating shaft 43 to reverse, and the rotating shaft 43 drives the material placement box 44 to reverse. During this process, the material blocking plate 48 moves the material back to its original position. The material blocking component 49 moves until the material blocking plate 491 and the rear blocking plate 412 limit the material.
