It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a schematic structural view of a rescue article placing device according to a first embodiment of the present invention. 2 is a schematic exploded view of the hook unit of FIG. 1. As shown in FIG. 1 and FIG. 2, the life-saving article placing device 100 provided in this embodiment specifically includes: a hook unit 1 and at least two rope assemblies 2 for connecting with different life-saving articles to be placed; the hook unit 1 has At least two locking portions, at least two locking portions can be opened and closed; when the locking portion is closed, each of the rope assemblies 2 can be locked by a corresponding locking portion for fixing the life-saving article 200 to be placed; at least two When the locking portions are sequentially opened, the rope assembly 2 can be unlocked in sequence with the locking portion for placing the life-saving article 200 to be placed.

Specifically, the life-saving article placing device 100 may be disposed on the unmanned aerial vehicle and connected to the frame or the body of the UAV by a structure such as a fastener or a fixing bracket. The life-saving article dispensing device 100 includes a hook unit 1 that is generally fixedly coupled to the unmanned aerial vehicle and has at least two latching portions on the hook unit 1. Each of the latches can be independently opened and closed to lock the cord assembly 2 or to unlock the cord assembly 2. When the locking portion is closed, the rope assembly 2 cannot be disengaged and locked on the locking portion; when the locking portion is opened, the originally locked portion of the rope assembly 2 can be disengaged from the locking portion, so that one end of the rope assembly 2 is Untie and release the life-saving items to be placed, and the life-saving items to be placed will be placed under the action of gravity to the designated place and rescue activities will be carried out. The other end of the rope assembly 2 is still fixedly connected to the UAV, so that it can be reused.

It should be noted that the rope assembly 2 may also be fixed only to the locking portion, and when the locking portion is opened, the rope assembly 2 as a whole is unlocked from the locking portion. Thus, after the limit of the hook unit 1 is lost, the rope assembly 2 is placed under the action of gravity with the life-saving item to be placed.

Since the latches on the hook unit 1 have at least two, each hook unit 1 can achieve positioning and locking of at least two rope assemblies. Each rope assembly 2 can be fixed with a life-saving item to be placed. When different locking parts realize their respective opening and closing functions, one or more pieces of different life-saving items to be placed can be dropped to achieve single-piece delivery or multiple-piece delivery. Features. The following is For ease of description, there are usually two locking portions on the hook unit 1, each for locking a rope assembly, and one rope assembly for fixing a life-saving article to be placed as an example. Of course, each of the locking portions is not limited to locking one rope assembly, and may also be used to lock two or more rope assemblies; each rope assembly is not limited to fixing one life-saving article to be placed, but may be two One or more quantities of lifesaving items to be placed.

Optionally, the locking portion can be a plurality of openable and closable structures, such as various types of hooks or opening and closing mechanisms, etc., and is not limited herein, as long as the locking portion can complete the locking and unlocking release of the rope assembly 2 can. For example, the locking and unlocking of the locking portion can be achieved by using the card slot and the notch structure. At this time, each of the locking portions may include a positioning groove 11 , and the notch 11 a of the positioning groove 11 may be opened and closed. When the notch 11a of the positioning groove 11 is closed, a closed space is formed in the positioning groove 11, so that the rope assembly 2 cannot be detached from the positioning groove 11 and locked in the positioning groove 11; when the notch 11a of the positioning groove 11 When opened, the cord assembly 2 can be unlocked and released. Since each locking portion includes a positioning groove, all the positioning grooves can be arranged in the same direction, so that when the notches of the positioning groove are sequentially opened, at least two rope components respectively locked in different positioning grooves can be sequentially The detachment from the positioning groove enables the sequential delivery of the lifesaving articles. Generally, since the size of the unmanned aerial vehicle is small, the positioning groove 11 on the hook unit 1 has a compact structure in order to facilitate the fixing and subsequent placement of the object on the unmanned aerial vehicle. Specifically, the at least two positioning slots may include a first positioning slot 111 and a second positioning slot 112. The first positioning slot 111 and the second positioning slot 112 are spaced apart in the same direction, when the slot of the first positioning slot 111 and the first slot When the slots of the two positioning slots 112 are sequentially opened, the two rope assemblies respectively locked in the first positioning slot 111 and the second positioning slot 112 can be detached from the first positioning slot 111 and the second positioning slot 112 in sequence. Since the positioning grooves are sequentially arranged in the same direction, the rope assembly 2 and the life-saving articles to be placed can also be placed in the order of the fixed positioning grooves in order, thereby effectively saving the space of the unmanned aerial vehicle while being carried out. During the delivery, the slots 11a of the positioning slot 11 can be sequentially opened, so that the life-saving items to be placed are sequentially dropped, and the placing process is convenient and quick. In addition, when the number of the positioning slots 11 is two or more, the positioning slots may also be arranged along the same direction, and details are not described herein again.

In order to facilitate the opening and closing operation of the notch 11a of the positioning groove 11, the hook unit can generally have a movable split structure. Specifically, the hook unit 1 may further include a movable member, the movable member is movably disposed at the notch 11a of the positioning groove 11, and the movable member is opposite to the positioning groove 11 When moving, the notches 11a of one or more positioning slots 11 can be opened.

The movable member for opening and closing the notch 11a of the positioning groove 11 can be of various structures and patterns. As a preferred embodiment, the movable member may be disposed as a locking lever 12, and the locking lever 12 is slidably disposed at the notch 11a of the positioning slot 11, and the sliding direction of the locking lever 12 is the same as the alignment direction of the positioning slot 11; When the locking lever 12 slides in the direction in which the positioning slots 11 are arranged, the locking lever 12 can sequentially pass through the slots of the at least two positioning slots to open one or more positioning slots.

For example, the hook unit 1 has a first positioning slot 111 and a second positioning slot 112. The hook unit 1 is provided with a through hole or a sliding slot for facilitating the translational sliding of the locking lever. The length of the locking lever 12 is long. Generally, it is longer than the total length of the first positioning groove 111 and the second positioning groove 112 at the notch 11a. When the locking rod 12 slides along the direction in which the positioning grooves 11 are arranged, the shaft of the locking rod 12 can sequentially lock the notches of the first positioning groove 111 and the second positioning groove 112. When the lock lever 12 slides in the reverse direction, the second positioning groove 112 and the first positioning groove 111 can be sequentially opened by staying at different positions. Specifically, when the shaft of the locking rod 12 is retracted from the slot of the second positioning slot 112, the second positioning slot 112 can be opened first; while the shaft of the locking rod 12 continues to retract from the slot of the first positioning slot 111. The second positioning slot 112 and the first positioning slot 111 can be ensured to be in an open state. The slidable locking rod 12 is used for locking, and the movement of the plurality of positioning grooves can be realized by only one moving piece, the operation is convenient and the reliability is high.

Because the space of the unmanned aerial vehicle is relatively compact, in order to realize the translational sliding of the locking rod 12 by using a simple structure, the through hole 13 can be opened in the groove wall of the positioning groove 11 near the notch 11a, and all the positioning grooves 11 are provided. The through holes 13 are oppositely disposed, and the locking rod 12 is bored in the through hole 13. Thus, the through holes in the respective positioning grooves together form a straight passage, and the locking rod 12 can freely slide and slide through the passage formed by the through holes to lock the notches 11a of the different positioning grooves 11. By providing the through holes 13 in the groove walls of the positioning grooves 11, it is possible to avoid the provision of complicated sliding guides on the hook unit 1, thereby simplifying the structure, saving space and reducing the weight of the entire apparatus.

In addition, it can be understood that the movable member can also be in other different structural styles. For example, the movable member may be an arc-shaped structural member spanning the notch 11a of each positioning groove 11, and when both ends of the curved structural member are connected with the notch 11a of the positioning groove 11, the rope assembly in the positioning groove 11 2 is locked; when one end of the curved structural member is unlocked and rotated about the other end, the notch 11a of the positioning groove 11 is opened, so that the rope assembly 2 located therein can be disengaged.

In order to drive the movable member for opening and closing the positioning groove 11, the hook unit 1 is correspondingly provided with a drive mechanism. For the case where the movable member is the lock lever 12, correspondingly, the drive mechanism of the hook unit 1 may further include a drive motor 14, a swing arm 15 and a link 16, wherein the output end of the drive motor 14 and the swing arm 15 The swing center is connected, the end of the swing arm 15 is hinged with the first end of the connecting rod 16, the second end of the connecting rod 16 is connected with the locking rod 12, and the swing arm 15 is swung around the swing center under the driving of the driving motor 14, the connecting rod 16 drives the lock lever 12 to cause sliding.

Specifically, the driving motor 14 can be a steering gear, and can generally be connected to a controller on the UAV to determine the rotation angle of the steering gear according to the electrical signal sent by the controller. The output end of the drive motor 14 is coupled to the swing center of the swing arm 15, and when the drive motor 14 rotates, the swing arm 15 is rotated to a different angular position. The lock lever 12 and the swing arm 15 are in a linked state, so that they can be slid to different positions under the swinging motion of the swing arm 15. Generally, when there are two positioning grooves on the hook unit 1, the swing angle of the swing arm 15 is approximately 90°, for example, when the swing arm 15 is in a direction almost parallel to the direction in which the positioning grooves 11 are arranged, the lock lever 12 is fully retracted, both positioning slots are in an open state; and when the swing arm 15 is located in a direction perpendicular to the direction in which the positioning slots 11 are arranged, the locking lever 12 is extended to a maximum length, so that the two positioning slots are locked; When the direction of the arrangement of the swing arm 15 and the positioning groove 11 is approximately 45°, that is, when the swing arm 15 is in the intermediate swing position, the first positioning slot 111 is still in the locked closed state, and the second positioning slot 112 is The notch is opened. Thus, by swinging the swing arm 15 to different angles, the sequential opening and closing of the different positioning grooves can be controlled.

Since the swinging arm 15 performs a rotary oscillating motion about the center of the swing, and the lock lever 12 reciprocates along a linear motion trajectory, the motion trajectories of the two are not coincident, so that the swing arm 15 and the lock lever 12 can also be disposed between The power transmitting link 16, the end of the swing arm 15 is hinged to the first end of the link 16, and the second end of the link 16 is coupled to the lock lever 12 such that the swing arm 15 swings around the swing center driven by the drive motor 14. At this time, the connecting rod 16 can drive the locking rod 12 to slide. Of course, in other embodiments, the determining motor 14 is not limited to driving the above-mentioned linkage mechanism, and the driving motor 14 can also drive a combination of a gear and a rack or drive a structure such as a cylinder or a hydraulic cylinder to convert the rotational motion into The linear motion, thereby driving the lock lever 12 in the present embodiment, achieves linear translational sliding.

Optionally, generally, in order to facilitate the placement, the hook unit 1 is generally fixed to the unmanned aerial vehicle in an approximately vertical posture, and the alignment direction of the positioning groove 11 is also approximately vertical. On the card When the hook unit 1 opens the notch 11a of the positioning groove 11 for the placement of the rope assembly 2, in order to facilitate the placement, the rope assembly 2 is prevented from being caught in the positioning groove 11 due to frictional factors and the like, and at least one groove wall of the positioning groove 11 is prevented. It should be a bevel. Thus, when the notch 11a of the positioning groove 11 is opened, the bevel groove wall cannot support the fixing rope assembly 2, which causes the rope assembly 2 to slide down the slope under the action of gravity, and finally disengages from the hook unit 1, thus effectively avoiding the hook The failure of the unit 1 due to the stuck of the rope assembly 2.

Accordingly, since the life-saving article 200 to be placed may have a different structure and shape, the rope assembly 2 includes a cord 21 for binding to the life-saving article to be placed in order to accommodate different shapes of the life-saving article. The flexible rope can be adapted to different shapes of the surface, and is conveniently fixed by placing the life-saving article 200 in a bundled manner, so that it can be applied to different shapes and different kinds of life-saving articles to be placed, so that the degree of freedom of placement is higher.

Optionally, the rope assembly 2 further includes a fixing ring 22 fixedly connected to the end of the rope 21, the fixing ring 22 can be inserted into or detached from the locking portion, and the rope 21 is locked by the fixing ring 22. It is detached from the hook unit 1 or from the hook unit 1. Since the fixing ring 22 is generally made of a hard material such as stainless steel and has a fixed shape, it is easy to handle. After the cable assembly 2 is provided with the fixing ring 22 for easy access, the quick connection and disassembly between the rope assembly 2 and the hook unit 1 can be realized, and the loading efficiency of the articles to be placed can be improved.

As a preferred embodiment, the rope 21 is typically an elastic cord. The elastic rope 21 can be tightly tied to the life-saving article to be placed by its own elastic force, and avoids the displacement and looseness caused by the unfastened binding of the life-saving article to be placed. Further, when the notch 11a of the positioning groove 11 is opened, the elastic cord can be easily detached from the positioning groove 11 by its own elastic force, further enhancing the reliability of the placement. Generally, the rope 21 can be made of a material such as a rubber band.

Specifically, the life-saving article 200 to be placed may be a lifebuoy or other item capable of being rescued. Hereinafter, the lifebuoy placement device 100 is used to realize the placement of the lifebuoy, and the rescue personnel are taken as an example for explanation. Typically, the cord assembly 2 can be cross-bundled onto the lifebuoy for secure attachment of the lifebuoy. In addition, the rope assembly 2 can also be attached directly to a portion of the lifebuoy to be coupled to the lifebuoy.
