[0002] Nowadays, the use of drone gimbals and other mounting devices for fixed-point shooting, throwing, observation or rescue is increasing. At the same time, when many drone throwing mounting devices on the market perform tasks, the drone needs to identify the position through an ordinary lens and use a servo to drive the hook for fixed-point throwing. Due to the numerous throwing tasks and different scenes, the objects to be thrown are also different. Traditional throwing devices have limitations such as inaccurate positioning, insufficient load weight and inconvenient operation. At the same time, the above limitations also affect the stability of the drone gimbal throwing load, waste resources in the drone flight mission, and fail to accurately complete the execution of the flight mission;

[0003] Many drone dropping devices are inconvenient and unstable to operate when performing traditional flight dropping tasks, whether for observation or dropping, due to the limitations of traditional structures. Usually, the work requirements are met by constantly adjusting the position of the drone and the weight of the dropped object, which brings great inconvenience and challenges to the drone flight operation, and also challenges the drone flight performance experience.

[0004] Most general drone dropping and mounting devices use simple lenses, servos, hooks and other structural parts, which are fixed in place with screws. This can lead to problems such as inaccurate positioning and insufficient load weight, bringing uncertainty to the stability of the dropping mission and limitations to the flight mission.

[0009] Furthermore, the hanging rod is used to rotate in a direction away from the opening when released.

[0010] Furthermore, an elastic member for driving the hanging rod to rotate in a direction away from the opening is provided between the hanging rod and the supporting frame.

[0011] Furthermore, the elastic member is a torsion spring, one end of the torsion spring abuts against a slot wall of the mounting slot, and the other end of the torsion spring abuts against the hanging rod.

[0012] Furthermore, an upper support plate is formed at the rotating free end of the hanging rod, and a lower support plate is formed at the telescopic end of the casting shaft for being arranged side by side with the upper support plate and supporting the upper support plate.

[0013] Furthermore, when the hanging rod is locked, the length direction of the hanging rod coincides with the length direction of the casting shaft, and the telescopic direction of the casting shaft coincides with the length direction of the casting shaft.

[0014] Furthermore, the support frame is provided with a sliding groove, the casting shaft is accommodated in the sliding groove and can move relative to the sliding groove, and the length of the protruding part of the casting shaft is less than or equal to the length of the part of the casting shaft located in the sliding groove.

In the description of this invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of this invention in conjunction with specific embodiments:

[0038] like Figures 1 to 3 As shown, the present embodiment provides a throwing device, which is used to be installed on a drone and is used to perform the task of throwing objects. When the drone travels to the destination, the throwing device releases the objects to the target location.

[0039] The throwing device comprises a support frame 1, a mounting slot 11 is formed on the support frame 1, and a throwing assembly 2 for closing and opening the opening is arranged at the opening of the mounting slot 11; when the throwing device is mounted on the drone, the opening of the mounting slot 11 is arranged downward, and during the flight of the drone, the opening is always downward, and the downward direction includes but is not limited to vertically downward and inclined downward, and this design facilitates that when the throwing assembly 2 opens the opening, the objects mounted on the throwing assembly 2 fall to the target location due to the effect of their own gravity;

[0040] The throwing assembly 2 includes a hanging rod 21 and a throwing shaft 22 respectively arranged on opposite side walls of the mounting slot 11. The hanging rod 21 is rotatably connected to one side wall of the mounting slot 11 and is used to hang the object to be thrown. The throwing shaft 22 is telescopically arranged on the other side wall of the mounting slot 11 and is used to lock and release the hanging rod 21. The telescopic end 221 of the throwing shaft 22 is used to extend a preset distance and dock with the rotating free end 211 of the hanging rod 21 to lock the hanging rod 21. The telescopic end 221 refers to the portion of the throwing shaft 22 exposed in the mounting slot 11, and the rotating free end 211 refers to The end of the hanging rod 21 is freely rotated and docked with the telescopic end 221, and the telescopic end 221 locks the hanging rod 21 and limits the rotation of the hanging rod 21, that is, the opening is closed, and the object to be thrown cannot be detached after being hung on the hanging rod 21; at the same time, the telescopic end 221 of the throwing shaft 22 is used to retract a preset distance and detach from the docking with the hanging rod 21 to release the hanging rod 21, and the telescopic end 221 releases the hanging rod 21 and no longer limits the rotation of the hanging rod 21, that is, the hanging rod 21 can rotate under the action of external force, that is, the opening can be opened under the action of gravity of the object to be thrown.

[0041] The working principle of the throwing device provided in this embodiment is as follows:

[0042] like Figure 4 As shown, when the object to be thrown needs to be mounted on the throwing assembly 2, the throwing shaft 22 is retracted to a preset distance and separated from the docking with the hanging rod 21. The preset distance is that the telescopic end 221 of the throwing shaft 22 is retracted to the point where it just no longer interferes with the rotating free end 211 of the hanging rod 21, and the hanging rod 21 is rotated to open the opening of the mounting slot 11, and the mounting part of the object to be thrown, such as a hook or a rope, is placed in the mounting slot 11; Figure 5 As shown, the hanging rod 21 is rotated to the opening of the mounting slot 11 and the free end 211 is rotated to face the telescopic end 221, and the throwing shaft 22 is extended again to a preset distance, and the preset distance is that the telescopic end 221 of the throwing shaft 22 contacts the rotating free end 211 of the hanging rod 21, and the hanging rod 21 provides support force. At this time, the object to be thrown is mounted on the hanging rod 21, and the throwing shaft 22 cooperates with the hanging rod 21 to support the object to be thrown. When the drone equipped with the throwing device is launched, the object to be thrown is mounted on the hanging rod 21 due to its own gravity;

[0043] When the object to be thrown needs to be thrown, please refer to Figure 4 , retract the extended throwing shaft 22 to a preset distance, and the telescopic end 221 of the throwing shaft 22 is separated from the rotating free end 211 of the hanging rod 21. The throwing shaft 22 no longer supports the hanging rod 21. Under the action of the gravity of the object to be thrown, the hanging rod 21 rotates downward to open the opening of the mounting slot 11, and the object to be thrown slides off the hanging rod 21 and is thrown.

[0044] The throwing device provided in this embodiment has the following technical effects:

[0045] The telescopic end 221 of the throwing shaft 22 extends out to lock the hanging rod 21 for mounting the object to be thrown. Through the cooperation of the throwing shaft 22 and the hanging rod 21, one end of the hanging rod 21 is fixed to the groove wall of the mounting groove 11, and the other end is connected to the throwing shaft 22 and then fixed, that is, both ends of the hanging rod 21 for mounting the thrown object are supported by corresponding structures, which not only improves the load-bearing capacity of the hanging rod 21, but also makes the release of the hanging rod 21 more flexible; in addition, since the hanging rod 21 is connected to the groove wall of the mounting groove 11 in a rotatable manner, the hanging rod 21 can be quickly opened downward under the action of the gravity of the object to be thrown, thereby improving the throwing speed and increasing the accuracy of throwing to the target location.

[0046] Furthermore, as a specific implementation of the throwing device provided in this embodiment, the number of hanging rods 21 is at least two, and at least two hanging rods 21 are arranged at intervals on the groove wall of the mounting groove 11. At the same time, the number of throwing axes 22 corresponds to the hanging rods 21, that is, the hanging rods 21 are controlled by the corresponding throwing axes 22, so that at least two objects to be thrown can be mounted, and can be thrown to at least two different target locations respectively.

[0047] Furthermore, as a specific implementation of the throwing device provided in this embodiment, the hanging rod 21 is used to rotate in a direction away from the opening when released. By setting the hanging rod 21 to rotate in a direction away from the opening, when the hanging rod 21 is released, the gravity direction of the object to be thrown is consistent with the rotation direction of the hanging rod 21, which is conducive to the object to be thrown being detached from the hanging rod 21.

[0048] Specifically, Figure 6 As shown, as a specific implementation of the throwing device provided in this embodiment, the hanging rod 21 is rotatably connected to the support frame 1 through the fixing pin 23, and the fixing pin 23 is fixedly arranged on the support frame 1. The hanging rod 21 rotates around the fixing pin 23. The hanging rod 21 can be rotated to a horizontal position or a vertical position, that is, the length direction of the hanging rod 21 is parallel to the horizontal direction or the length direction of the hanging rod 21 is parallel to the vertical direction. When the hanging rod 21 is rotated to be parallel to the vertical direction, the object to be thrown mounted on the hanging rod 21 slides off the hanging rod 21.

[0049] Furthermore, as a specific implementation of the throwing device provided in this embodiment, an elastic member 24 for driving the hanging rod 21 to rotate in a direction away from the opening is provided between the hanging rod 21 and the support frame 1. By providing the elastic member 24, the hanging rod 21 can be quickly rotated in a direction away from the opening, thereby achieving the purpose of quickly opening the opening. When the drone reaches the target location, the throwing shaft 22 is driven to be separated from the hanging rod 21, and the hanging rod 21 is quickly rotated under the elastic force of the elastic member 24, and the opening is quickly opened to release the object to be thrown.

[0050] Further, as a specific implementation of the throwing device provided in this embodiment, the elastic member 24 is a torsion spring, one end of which is against the wall of the mounting slot 11, and the other end of which is against the hanging rod 21. The torsion spring is movably sleeved on the fixing pin 23, and the two ends with elastic force are respectively against the wall of the mounting slot 11 and the hanging rod 21.

[0051] For further information, please also refer to Figure 6 and Figure 7 As a specific implementation of the casting device provided in this embodiment, the rotating free end 211 of the hanging rod 21 is formed with an upper abutment plate 212, and the telescopic end 221 of the casting shaft 22 is formed with a lower abutment plate 222. The lower abutment plate 222 is used to be arranged side by side with the upper abutment plate 212 and support the upper abutment plate 212 when the casting shaft 22 is connected to the hanging rod 21. A first meshing portion 213 is formed between the upper abutment plate 212 and the end surface of the rotating free end 211, and a second meshing portion 223 is formed between the lower abutment plate 222 and the end surface of the telescopic end 221. The first meshing portion 213 and the second meshing portion 223 mesh with each other when the casting shaft 22 is connected to the hanging rod 21 to achieve a mutually stable fixation effect. In addition, the surface where the upper abutment plate 212 and the lower abutment plate 222 abut against each other is a plane, and the lower abutment plate 222 can provide a stable support force to the upper abutment plate 212.

[0052] Further, please refer again to Figure 5 As a specific implementation of the throwing device provided in this embodiment, when the hanging rod 21 is locked, the length direction of the hanging rod 21 coincides with the length direction of the throwing shaft 22, and the extension direction of the throwing shaft 22 coincides with the length direction of the throwing shaft 22, and the length directions of the throwing shaft 22 and the hanging rod 21 are perpendicular to the vertical direction. Specifically, the hanging rod 21 and the throwing shaft 22 are cylindrical in shape, and the length direction of the hanging rod 21 coincides with the length direction of the throwing shaft 22, that is, the hanging rod 21 and the throwing shaft 22 are coaxially arranged. Through this design, when the hanging rod 21 is loaded, the load can be evenly distributed to the hanging rod 21 and the throwing shaft 22, thereby improving the load-bearing capacity of the hanging rod 21 and preventing the hanging rod 21 from being damaged due to excessive pressure exerted on the hanging rod 21 by the object to be thrown.

[0053] Furthermore, if Figure 8As shown, as a specific implementation of the casting device provided in this embodiment, the support frame 1 is provided with a sliding groove 12, the casting shaft 22 is accommodated in the sliding groove 12 and can move relative to the sliding groove 12, and the length of the protruding part of the casting shaft 22 is less than or equal to the length of the part of the casting shaft 22 located in the sliding groove 12. The casting shaft 22 is loosely fitted in the sliding groove 12, and the length of the protruding part of the casting shaft 22 is set to be less than or equal to the length of the part of the casting shaft 22 located in the sliding groove 12, so that the protruding part of the casting shaft 22 can provide a larger supporting force to the hanging rod 21. Preferably, the casting shaft 22 is only formed at the lower support plate 222 of the telescopic end 221 of the casting shaft 22, which protrudes out of the sliding groove, that is, most of the casting shaft 22 is accommodated in the sliding groove 12, and the groove wall of the sliding groove 12 can provide a larger fixing force for the casting shaft 22, so that the casting shaft 22 provides a larger supporting force to the hanging rod 21, thereby improving the load-bearing capacity of the hanging rod 21; in addition, only the lower support plate 222 protrudes out of the sliding groove 12, so that when the casting shaft 22 releases the hanging rod 21, the preset distance that the telescopic end 221 retracts is shorter, thereby achieving the effect of quickly detaching from the hanging rod 21 to quickly release the hanging rod 21.

[0054] Furthermore, as a specific implementation of the casting device provided in this embodiment, the length of the hanging rod 21 is less than or equal to half the length of the casting shaft 22, so that the casting shaft 22 can provide a larger supporting force while maintaining the telescopic movement of the casting shaft 22.

[0055] For details, please also refer to Figure 7 and Figure 8 As a specific implementation of the casting device provided in this embodiment, a rack 224 is provided on the surface of the casting shaft 22 along its own length direction, and a driving gear 13 for driving the casting shaft 22 to move along its own length direction is provided inside the support frame 1. The driving gear 13 is meshed with the rack 224 to convert the rotation of the driving gear 13 into the movement of the casting shaft 22 along its own length direction. The driving gear 13 is driven to rotate by a motor, and specifically, the motor is a steering gear. A slot 121 corresponding to the driving gear 13 is opened on the slot wall of the sliding slot 12, and the rack 224 is exposed in the slot 121, and the driving gear 13 meshes with the rack 224 at the slot 121.

[0056] Specifically, as a specific implementation of the casting device provided in this embodiment, a guide groove 122 is provided on the support frame 1 along the telescopic direction of the casting shaft 22, and a guide screw 225 sliding in the guide groove 122 is provided on the casting shaft 22. The length of the guide groove 122 is preferably the length of the upper support plate 212. Through this design, the guide groove 122 not only guides the casting shaft 22 to telescopically move in a preset direction, but also, by limiting the length of the guide groove 122, the casting shaft 22 can be telescoped within a limited length range, so as to achieve the purpose of rapid extension and retraction, thereby further accelerating the speed of releasing the hanging rod 21.

[0057] Further, please refer again to Figure 2 As a specific implementation of the throwing device provided in this embodiment, a camera assembly 3 and a control assembly electrically connected to the camera assembly 3 are provided on the support frame 1, and the control assembly is used to electrically connect to the throwing assembly 2. When the control assembly detects that the photo sent back by the camera assembly 3 includes the target location, it analyzes the throwing timing according to the flight speed, attitude, altitude and other information of the drone, and outputs control information to the throwing assembly 2 to throw the object.

[0058] Specifically, as a specific implementation of the throwing device provided in this embodiment, the camera assembly 3 includes a camera bracket 31 and a panoramic camera 32 respectively arranged on two opposite sides of the camera bracket 31. The camera bracket 31 is fixedly set on the support frame 1, and the two sides of the support frame 1 are provided with shock-absorbing rings 33 wrapped around the panoramic camera 32. The shock-absorbing rings 33 are used to protect the panoramic camera 32 and reduce the vibration of the panoramic camera 32, so as to prevent the panoramic camera 32 from shaking and causing the taken photos to be blurred, thereby causing the target location to be unable to be acquired normally.

[0059] Furthermore, as a specific implementation of the throwing device provided in this embodiment, the camera assembly 3 also includes a network image transmission board 34 arranged inside the camera bracket 31 and connected to the panoramic camera 32. The network image transmission board 34 is used to send the image captured by the panoramic camera 32 to a receiving device on the ground, so that the user can analyze the flight information of the drone. At the same time, a camera circuit board 35 connected to the network image transmission board 34 and the panoramic camera 32 are arranged side by side inside the camera bracket 31 and side by side with the network image transmission board 34. The camera circuit board 35 is used to control the operation of the panoramic camera 32. A silent fan 36 is arranged on the inner side surface of the camera bracket 31 at a position facing the network image transmission board 34 and the camera circuit board 35. The silent fan 36 is used to discharge the heat in the camera bracket 31 to prevent the internal temperature of the throwing device from being too high and causing the components to malfunction.

[0060] Furthermore, as a specific implementation of the throwing device provided in this embodiment, the throwing device includes a protective shell 4, which includes a lower cover 41 and an upper cover 42 that can be detached from the lower cover 41. A protective space for protecting the support frame 1, the camera bracket 31 and the components arranged on the support frame 1 and the camera bracket 31 is formed between the lower cover 41 and the upper cover 42. The support frame 1 is fixedly arranged inside the lower cover 41 to increase the supporting strength of the support frame 1 and prevent external forces from damaging the components arranged on the support frame 1. At the same time, the lower cover 41 is provided with a protective groove 411 corresponding to the mounting groove 11. The shape of the protective groove 411 is similar to that of the mounting groove 11, which increases the strength of the groove wall of the mounting groove 11, thereby enhancing the load-bearing capacity of the hanging rod 21 and the throwing shaft 22 arranged on the two opposite side walls of the mounting groove 11.

[0061] For further information, please also refer to Figure 2 and Fig. 9 As a specific implementation of the throwing device provided in this embodiment, the upper surface of the protective shell 4 is rotatably connected with a quick-release component 5, and the quick-release component 5 is used for quick connection and removal with the drone. When the quick-release component 5 is fixed to the drone, the protective shell 4 can rotate relative to the quick-release component 5, that is, the main body of the throwing device can rotate relative to the drone, which is conducive to the throwing device rotating in different throwing directions to throw objects;

[0062] The quick-release assembly 5 includes a quick-release upper shell 511 and a quick-release lower shell 512 installed on the quick-release upper shell 511. A receiving space is formed between the quick-release upper shell 511 and the quick-release lower shell 512. The receiving space is provided with an interface circuit board. One end of the quick-release lower shell 512 is provided with a plurality of interfaces connected to the interface circuit board. The interfaces are used to dock with the interfaces of the drone. Both sides of the quick-release lower shell 512 are provided with fixed guide rails 52. The fixed guide rails 52 are used to be inserted into the corresponding fixed grooves of the drone to achieve the purpose of quick installation and removal.

[0063] In addition, a locking boss 53 is respectively provided at the end of the two fixed guide rails 52, and the locking boss 53 is used to be inserted into and removed from the corresponding locking groove of the drone to further reinforce the quick release assembly 5 that has been locked on the drone. In this embodiment, the locking boss 53 is telescopically arranged on the quick release upper shell 511, that is, the locking boss 53 can be retracted into the inside of the quick release upper shell 511, and can also be extended to the outside of the quick release upper shell 511. The locking boss 53 is connected to the first elastic part 54 inside the quick release upper shell 511, and the first elastic part 54 provides elastic force for the locking boss 53 to extend out of the quick release upper shell 511. The locking boss 53 extends to be inserted into the fixed groove. At the same time, the locking boss 53 can be driven to retract to the inside of the quick release upper shell 511 by the pressing key 55 arranged on the quick release upper shell 511, so as to facilitate the removal of the throwing device from the drone. The cooperation between the pressing key 55 and the locking boss 53 is as follows: a retractable abutment portion 56 is provided at the end of the locking boss 53 located inside the quick-release upper shell 511; the pressing key 55 is retractably provided on the quick-release upper shell 511 for the user to press toward the inside of the quick-release shell 51; the pressing key 55 is provided with a wedge-shaped portion 57 protruding toward the inside of the quick-release upper shell 511 and abutting against the retractable abutment portion 56; the wedge-shaped portion 57 is used to move toward the inside of the quick-release upper shell 511 under the drive of the pressing key 55; under the squeezing action of the wedge-shaped portion 57, the retractable abutment portion 56 is simultaneously retracted toward the quick-release upper shell 511. The upper shell 511 moves internally, and then the retracted abutment portion 56 drives the locking boss 53 to retract into the interior of the quick-release upper shell 511; when the user no longer presses the push button 55, the push button 55 moves toward the outside of the quick-release upper shell 511 under the elastic force of the second elastic portion 58 connected to the retracted abutment portion 56, and the wedge-shaped portion 57 no longer applies a squeezing force on the retracted abutment portion 56. The locking boss 53 extends out of the quick-release upper shell 511 under the elastic force of the first elastic portion 54, and can be stuck in the locking groove of the drone, thereby connecting the throwing device to the drone.

[0064] This embodiment also provides a drone, which is provided with the above throwing device. The drone provided with the above throwing device has the advantage of fast throwing speed.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
