[0008] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. Among them:

[0011] Figure 3 yes Figure 1 An enlarged view of the second embodiment of the throwing device is shown. [Specific implementation method]

[0012] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] Please refer to Figure 1 and Figure 2 The drone 100 is used to transport and deliver materials with magnetic parts (not shown), and includes a fuselage 1, a signal acquisition device 5, and a throwing device 7. The throwing device 7 includes a soft magnetic body 73, a coil 71, and a controller (not shown). The soft magnetic body 73 is arranged below the drone 100 and is used to magnetically connect the materials; the coil 71 and the soft magnetic body 73 are spaced apart; the controller is electrically connected to the coil 71 and is used to control the coil 71 to generate a magnetic field, thereby pushing the materials to separate from the soft magnetic body 73; the soft magnetic body 73 and the coil 71 are spaced apart below the fuselage 1.

[0014] The controller is disposed within the fuselage 1 and is electrically connected to the signal acquisition device 5 and the coil 71. The drone 100 collects the casting environment signal and the casting control signal through the signal acquisition device 5 and feeds them back to the controller, thereby controlling the coil 71 in the casting device 7 to form a magnetic field, thereby achieving the casting function.

[0015] The throwing device 7 is provided with a coil 71, which is electrically connected to the controller. The controller controls the current flowing through the coil 71, thereby controlling the working state of the throwing device 7. Due to the provision of the coil 71, a magnetic field can be formed by controlling the current change.

[0016] Magnetic materials (such as magnets) can be installed in the materials to cooperate with the soft magnetic body 73 for magnetic fixation. The soft magnetic body 73 and the coil 71 are spaced apart from each other in the fuselage 1. The soft magnetic body 73 can provide a certain magnetic attraction without being connected to the controller, thereby reducing the loss of electric energy during transportation. When throwing is required, the controller controls the coil 71 to form a magnetic field, which corresponds to the magnetic poles of the magnet installed in the materials, forming a thrust to push the materials in a direction away from the soft magnetic body 73 to achieve throwing.

[0017] The soft magnetic body 73 can be installed on the same side of the body 1 as the coil 71, or on the opposite side of the body 1. This is not a limitation. In this embodiment, it is preferably installed on the same side of the body 1 as the coil 71 to maximize the magnetic attraction for securing the material and provide greater thrust when the coil 71 forms a magnetic field.

[0018] In addition, the throwing device 7 is arranged as far as possible below the center of gravity of the fuselage 1, that is, the coil 71 and the soft magnetic body 73 should be arranged just below the center of gravity of the fuselage 1 to keep the drone 100 stable during flight.

[0019] The coil 71 is mainly a coil wound with metals such as copper and aluminum, which can increase the area in contact with the materials and is lightweight, convenient for transportation and saves energy. Correspondingly, the soft magnetic body 73 can be made of metal. In the present embodiment, the coil 71 is a toroidal coil, and the soft magnetic body 73 is a cylindrical iron block. The soft magnetic body 73 is located at the center of the coil 71 so that the coil 71 and the soft magnetic body 73 cooperate with each other, which can not only stably transport and deliver materials, but also save energy.

[0020] It should be noted here that the number of the soft magnetic bodies 73 can be two or more, and they are arranged around the coil 71 at intervals. By increasing the number of the soft magnetic bodies 73, the magnetic attraction during transportation can be further increased; and the soft magnetic bodies 73 are evenly arranged around the coil 71 to ensure balanced attraction.

[0021] Please continue to combine Figure 3In another embodiment, the number of the soft magnetic bodies 73 is preferably 8, evenly distributed around the coil 71. The overall structure of the soft magnetic body 73 is square, which is convenient for production and processing and installation. Of course, in another embodiment, the soft magnetic body 73 can also be a ring magnet, a plurality of square magnets, or a plurality of cylindrical magnets. There is no limitation on the appearance of the soft magnetic body 73.

[0022] The throwing device 7 is also provided with a positioning structure 77, which is spaced apart from the coil 71 and the soft magnetic body 73 and is used to fix the position of the material. In this embodiment, the positioning structure 77 can cooperate with the material to fix the position, prevent the material from rotating or shaking during transportation, and ensure the stability of the transportation process. The number of the positioning structures 77 is two or more, and the coil 71 is provided between each of the positioning structures 77. In this embodiment, the number of the positioning structures 77 is preferably two, so as to achieve position fixation with a minimum number and reduce the weight of the overall structure.

[0023] In this embodiment, the throwing device 7 further includes a mounting boss 75, which is fixed to one side below the fuselage 1, and the coil 71, the soft magnetic body 73, and the positioning structure 77 are all provided on the mounting boss 75. For materials whose structures are not completely flat, they may directly partially abut against the fuselage 1, and there may be a gap between the magnetic part and the soft magnetic body 73 and the coil 71, resulting in insufficient magnetic attraction. The mounting boss 75 can make the materials fit more closely with the soft magnetic body 73 and the coil 71, thereby enhancing suction and thrust, making transportation more stable, throwing more powerful, and expanding the range of transportable materials.

[0024] The signal acquisition device 5 includes a camera unit and a communication unit. The camera unit can be a camera that can be installed on a drone in the prior art, and the communication unit can be an existing communication unit such as Bluetooth, Wi-Fi, LTE, LPWAN, GPS, etc. The frequency bands used for the transmission of data and control instructions between the signal acquisition device 5 and the ground station or control terminal mainly include 2.4 GHz and 5.8 GHz. Among them, the 2.4 GHz frequency band is mainly used for remote control and image transmission, while the 5.8 GHz frequency band is used for data link communication, which is not limited here.

[0025] The working principle of the drone 100 is described as follows:

[0026] The throwing device 7 and the material are fixed by the magnetic attraction principle, that is, the soft magnet 73 is used for magnetic attraction and the positioning structure 77 is used for position fixation.

[0027] The signal acquisition device 5 collects the casting environment signal and the casting control signal and feeds them back to the controller, thereby generating a magnetic field in the coil 71. The casting environment signal is primarily a video signal captured by the camera unit, which is used to determine whether it is the casting location. The casting control signal includes a user control signal received by the communication unit. The user can send a control signal through a corresponding terminal device such as a mobile phone, computer, or ground station, thereby controlling the current flowing through the coil 71 through the controller to form a magnetic field. This magnetic field exerts a reverse repulsive force on the material. When the sum of the repulsive force and the gravity of the material is greater than the attractive force of the soft magnetic body 73, the casting of the material is completed.

[0028] Compared to existing technologies, the throwing device 7, by providing the coil 71 and the soft magnetic body 73, utilizes the principles of magnetic attraction and the magnetic field formed by current flowing through the coil 71 to achieve switching between a fixed state and a released state. Furthermore, the overall structure is simple, compact, lightweight, and easy to install, reducing production costs. A drone 100 employing the throwing device 7 can easily secure the material using the soft magnetic body 73, and the controller controls the coil 71 to form a magnetic field, promoting the separation of the material. The entire securing, transporting, and throwing process is flexible, convenient, and rapid, significantly improving throwing efficiency.

[0029] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
