Description

Technical Field

[0001] This utility model belongs to the field of drone delivery technology and relates to a multi-rotor drone-mounted dual portable lifebuoy delivery bin. Background Technology

[0002] Drowning is a leading cause of accidental death among children in my country. Due to the rapid progression of drowning, enhancing emergency response capabilities and improving search and rescue efficiency are crucial. However, my country's water rescue infrastructure is weak, lacking equipment and key technologies, resulting in low search and rescue efficiency and danger, easily leading to missed rescue opportunities, especially in dangerous or extreme weather conditions. With the rapid development of drone technology, multi-rotor drones, due to their superior vertical takeoff and landing, maneuverability, and high stability, can achieve rapid rescue by carrying lifebuoys. However, traditional lifebuoy deployment methods using drones often suffer from limitations. Traditional cable-based non-portable lifebuoy deployment mechanisms have a flexible connection to the drone, leading to significant placement deviations due to structural sway, making accurate deployment difficult. Rigid left and right mounting structures capable of carrying portable lifebuoys can cause the aircraft's center of gravity to shift during the time between deployment and incomplete deployment, resulting in instability. While these methods can improve rescue efficiency to some extent, they often suffer from poor deployment accuracy due to cable connections and can only carry one lifebuoy at a time. Inaccurate placement wastes rescue time. The existing deployment structure has problems such as the inability to deploy multiple lifebuoys at different times or locations, the limited number of lifebuoys that can be carried, and the impact of the deployment device on the aircraft's flight balance during operation. Utility Model Content

[0003] The purpose of this invention is to provide a dual portable lifebuoy delivery bay for multi-rotor drones, in order to solve the technical problems of poor delivery accuracy and low delivery efficiency in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-rotor drone-mounted dual portable lifebuoy delivery bay includes: a bay body, with the upper end of the bay body mounted on the drone; a baffle slidably installed on one side of the bay body; a partition inside the bay body; a cargo bay floor at the bottom of the bay body; the partition inside the bay body being parallel to the cargo bay floor and hinged to a side wall inside the bay body perpendicular to the baffle; and the cargo bay floor being hinged to another side wall inside the bay body perpendicular to the baffle. A control bay is located outside the bay body for controlling the opening and closing of the partition inside the bay body and the cargo bay floor through its internal linkage structure and rudder fan.

[0006] Preferably, the upper end of the container is provided with a number of mounting connection points, which are used to fix the drone.

[0007] Preferably, a groove is provided on one side of the silo body, and the baffle is slidably disposed on the silo body by adapting to the groove.

[0008] Preferably, a vertical cylinder is provided on one side of the control compartment, a connecting rod structure is set inside the vertical cylinder, a servo motor is provided on one side of the vertical cylinder, a servo fan is set at the lower end of the vertical cylinder and contacts the connecting rod structure, and the servo fan is connected to the servo motor. A through hole adapted to the servo fan is opened on the side wall of the control compartment, the servo fan passes through the through hole and contacts the cargo compartment floor plate, and is used to control the opening and closing of the cargo compartment floor plate. Below the servo fan is the control compartment bottom cover, the control compartment bottom cover is fixed to the control compartment, and a through hole not smaller than the radial dimension of the connecting rod structure is opened on the control compartment bottom cover.

[0009] Preferably, the linkage structure includes a linkage, one end of which is hinged to the bottom of the partition in the compartment, and the other end is hinged to a hexagonal post through a connector. The hexagonal post is vertically installed in the control compartment, and a universal ball is connected to the bottom of the hexagonal post.

[0010] Preferably, the top of the control compartment is also provided with a control compartment cover, which is fixed to the side wall of the compartment body. The connecting rod structure is located below the control compartment cover and passes through the side wall of the compartment body and is hinged to the bottom of the partition in the compartment.

[0011] Preferably, the bottom of the partition in the warehouse is provided with a connecting part adapted to the connecting rod structure, and the bottom of the partition in the warehouse is hinged to the connecting rod structure through the connecting part.

[0012] Preferably, when the portable life ring is being filled, the baffle moves upward along the slide groove to open one side of the compartment; when the portable life ring is filled, the baffle moves downward along the slide groove to close one side of the compartment.

[0013] Preferably, when it is not necessary to deploy portable life rings, the rudder fan passes through the side wall of the cargo compartment and contacts the lower surface of the cargo compartment floor to control the closure of the cargo compartment floor;

[0014] When the first layer of portable lifebuoys needs to be deployed, the rudder fan rotates 90°, the cargo hold floor opens, the partition in the cargo hold closes, and the portable lifebuoys are deployed.

[0015] Preferably, when it is necessary to deploy the second layer of portable lifebuoys, the rudder fan rotates another 45°, the lower end of the linkage structure moves downward, causing the partition in the compartment to open and deploy the portable lifebuoys.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This application discloses a dual portable lifebuoy delivery bay mounted on a multi-rotor UAV, enabling rapid multi-point delivery of lifebuoys. Compared to UAVs carrying traditional non-portable lifebuoys, this design not only increases the number of lifebuoys carried but also, compared to devices capable of airdropping portable lifebuoys but not yet used in this field, fully considers the impact of load and stability during delivery on the UAV. Furthermore, compared to single-bay devices, it improves fault tolerance by using a partition to divide the interior into two spaces, increasing space utilization and facilitating the simultaneous loading of more portable lifebuoys, significantly increasing the likelihood of mission success. This application employs a vertically mounted structure design, vertically designing multiple portable lifebuoy bays to ensure that the center of gravity projection on the horizontal plane does not change during the delivery process. A robust, fixed rigid structure design is adopted to completely solve the structural swaying problem that may occur during flight in traditional cable-based delivery methods. This fixed rigid structure significantly improves stability compared to traditional cable structures.

[0018] The portable lifebuoy's lower compartment opening and closing structure utilizes a linkage mechanism for the upper compartment and a rotating baffle for the lower compartment. When deployment is needed, simply controlling the servo motor's rotation angle allows each lifebuoy compartment's opening to be operated individually or simultaneously, depending on the specific needs of the rescue site. For rapid lifebuoy deployment, operators can easily control the linkage to open both compartments simultaneously, achieving synchronized deployment. In other situations, if only one target needs rescue, only one compartment's opening can be operated while the other remains closed, thus avoiding unnecessary resource waste.

[0019] The baffle is conveniently located on the side of the drone and has a groove designed on the cabin. The baffle can be installed along the groove, allowing rescuers to easily fill the portable life ring in a short time without complicated tools. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings:

[0037] See Figures 1-6This application discloses a dual portable lifebuoy delivery bay mounted on a multi-rotor UAV, comprising: a bay body 1, which is mounted on the upper part of the bay body 1; a baffle 8 slidably disposed on one side of the bay body 1; a partition 9 disposed inside the bay body 1; and a cargo bay floor 5 disposed at the bottom of the bay body 1. The partition 9 is parallel to the cargo bay floor 5 and is hinged to a side wall of the bay body 1 perpendicular to the baffle 8. The cargo bay floor 5 is hinged to another side wall of the bay body 1 perpendicular to the baffle 8. A control bay 3 is disposed on the outside of the bay body 1 for controlling the opening and closing of the partition 9 and the cargo bay floor 5 through an internal linkage structure and a rudder fan 15. This application adopts a design concept of upper and lower mounting structure, vertically designing multiple portable lifebuoy bays to ensure that the center of gravity projection on the horizontal plane does not change during the delivery process. A robust fixed rigid structure design is adopted to completely solve the structural swaying problem that may occur during flight in traditional cable delivery schemes. This fixed rigid structure significantly improves stability compared to traditional cable structures. A partition divides the interior into two spaces, increasing space utilization and allowing for the simultaneous loading of more portable lifebuoys, greatly increasing the likelihood of mission success. The opening and closing mechanism of the lower cover of the portable lifebuoy compartment utilizes a linkage structure for the upper compartment and a rotating baffle for the lower compartment. When deployment is needed, simply controlling the angle of the servo motor allows each lifebuoy compartment opening individually or simultaneously, depending on the specific needs of the rescue site. For rapid lifebuoy deployment, operators can easily control the linkage to open both compartments simultaneously, achieving synchronized deployment. In other situations, if only one target needs to be rescued, only one compartment can be opened while the other remains closed, avoiding unnecessary resource waste.

[0038] In some embodiments, a plurality of mounting connection points 7 are evenly provided on the upper end of the housing 1, and the housing is fixedly connected to the drone through the mounting connection points 7. The design concept of the upper and lower mounting structure is to vertically design multiple portable life ring housings, thereby ensuring that the center of gravity projection on the horizontal plane does not change during the throwing process.

[0039] In some embodiments, a groove 6 is provided on one side of the compartment 1, and a baffle 8 is slidably disposed on the compartment 1 by adapting to the groove 6. The baffle is located in a convenient position on the side of the drone. The groove is designed on the compartment, and the baffle can be installed along the groove, allowing rescuers to easily complete the loading of the portable lifebuoy in a short time without complicated tools.

[0040] In some embodiments, a vertical cylinder 16 is provided on one side of the control compartment 3, a connecting rod structure is provided inside the vertical cylinder 16, a servo motor 13 is provided on one side of the vertical cylinder 16, a servo fan 15 is provided at the lower end of the vertical cylinder 16 and contacts the connecting rod structure, and the servo fan 15 is connected to the servo motor 13. A through hole adapted to the servo fan 15 is provided on the side wall of the control compartment 3, and the servo fan 15 passes through the through hole and contacts the cargo compartment floor 5 to control the opening and closing of the cargo compartment floor 5. Below the servo fan 15 is the control compartment bottom cover 4, and a through hole not smaller than the radial dimension of the connecting rod structure is provided on the control compartment bottom cover 4. The control compartment bottom cover 4 is fixedly connected to the control compartment 3.

[0041] In some embodiments, the linkage structure includes a link 10, one end of which is hinged to the bottom of the partition 9 in the compartment, and the other end is hinged to a hexagonal post 12 via a connector 11. The hexagonal post 12 is vertically disposed in the control compartment 3, and a universal ball 14 is connected to the bottom end of the hexagonal post 12. The universal ball 14 changes sliding friction to rolling friction, thereby improving the lifespan of the device.

[0042] In some embodiments, the top of the control compartment 3 is also provided with a control compartment cover 2, which is fixed to the side wall of the compartment body 1. The connecting rod structure is located below the control compartment cover 2, passes through the side wall of the compartment body 1, and is hinged to the bottom of the compartment partition 9.

[0043] In some embodiments, the bottom of the partition plate 9 is provided with a connecting part adapted to the linkage structure, and the bottom of the partition plate 9 is hinged to the linkage structure through the connecting part.

[0044] In some embodiments, when the portable life ring is being filled, the baffle 8 moves upward along the slide 6 to open one side of the compartment 1, and when the portable life ring is filled, the baffle 8 moves downward along the slide 6 to close one side of the compartment 1.

[0045] In some embodiments, see Figure 7 When there is no need to deploy the portable lifebuoy, the rudder fan 15 passes through the side wall of the cargo body 1 and contacts the lower surface of the cargo floor 5 to control the cargo floor 5 to close.

[0046] When the first layer of portable lifebuoys needs to be deployed, the rudder fan 15 rotates 90°, the cargo compartment floor 5 opens, the compartment partition 9 closes, and the portable lifebuoys are deployed.

[0047] In some embodiments, see Figure 8 When it is necessary to deploy the second layer of portable lifebuoys, the rudder fan 15 rotates 45°, the lower end of the linkage structure moves downward, causing the partition 9 in the compartment to open and deploy the portable lifebuoys.

[0048] The portable life ring has the ability to automatically and quickly inflate when it comes into contact with water.

[0049] See Figure 1First, the connection, assembly, and function of each component will be introduced. The baffle 8 is inserted into the slide groove 6, its function being to facilitate the loading of portable lifebuoys while preventing them from falling out. Inside the compartment 1, there is a central partition 9 (a single-door hinged panel) in the middle section, the purpose of which is to separate the two portable lifebuoys. The bottom of the compartment 1 also uses an embedded hinge to prevent goods from falling out. The central partition 9 is connected to the left side of the compartment wall by a pin, and the compartment floor 5 is connected to the right side of the compartment wall.

[0050] See Figure 2 The connecting rod 10 is connected to the compartment partition 9 and the connector 11 via pins. The top of the hexagonal column 12 is connected to the connecting rod 10 via the connector 11, and the bottom is connected to the universal ball 14 via a screw hole.

[0051] See Figure 3 The connector 11, hexagonal post 12, and universal ball 14 are inserted into the vertical cylinder 16 in the control compartment (ensuring that it can only move vertically). The purpose of using the universal ball 14 is to change sliding friction to rolling friction to reduce frictional resistance. The servo motor 13 is fixed in the control compartment by screws.

[0052] See Figure 4 The servo motor 13 is connected to the servo fan 15. The servo fan 15 has two functions: first, it blocks the cargo compartment floor 5 to prevent it from opening; second, it blocks the hexagonal column 12 and the universal ball 14 so that it will not fall out of the round hole in the control compartment floor cover 4 under the condition that the conditions are not met, thereby ensuring that the compartment partition 9 will not open.

[0053] The control compartment is fixedly connected to the compartment body 1. Portable life rings are respectively placed in the two layers of cargo compartments separated by partition 9 in the compartment. The compartment body 1 is connected to the drone through the mounting connection point 7 using four studs.

[0054] Example

[0055] Once the portable lifebuoy is assembled, close the baffle 8 to prevent it from being thrown out during flight.

[0056] During the deployment of the portable lifebuoy, a servo motor 13 is used to separate and drop the cargo. A linkage structure controlled by the servo motor is installed on the outside of the cargo box, consisting of a link 10, a connector 11, a hexagonal column 12, and a swivel ball 14. During flight, to prevent the portable lifebuoy from falling out of the storage compartment, a servo fan 15 is used to hold the hinged bottom cover 4 at the bottom of the cargo box. When the servo motor rotates 90°, the hinge opens, and the first layer of cargo in the cargo box is thrown out. Because the servo fan 15 is holding the swivel ball 14 in place, the linkage structure remains in its original state, keeping the second layer of hinged flaps, i.e., the compartment partition 9, closed.

[0057] At this point, the cabin partition 9 can be opened manually or by drone. If it is necessary to release the second portable lifebuoy, the rudder fan 15 can be rotated 45° to make the omnidirectional ball 14 fall, along with the hexagonal column 12, thereby opening the cabin partition 9 controlled by the linkage structure and releasing the second portable lifebuoy.

[0058] Through the aforementioned technical solutions, this application enables the UAV to effectively avoid imbalance problems caused by center of gravity shift during loading, deployment, and recovery. The rigid structure provides the UAV with extremely high control precision, ensuring that it can accurately deploy personnel point-to-point according to their precise locations during rescue missions. The time-sharing opening and closing structure allows for multi-point rescue missions and reduces resource waste. Simultaneously, the quick-release mechanism of the quick-release baffle significantly reduces loading time, gaining valuable time for rescue operations.

[0059] 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.
