[0041] As attached Figure 1 To Attachment Figure 7 As shown, an embodiment of the utility model discloses a drone throwing device, including a shell 2 and a throwing mechanism 3, the throwing mechanism 3 is used to detachably connect the throwing object 4 to the shell 2; the throwing mechanism 3 includes a transmission assembly 31 and a plug-in assembly 32; the transmission assembly 31 includes a rack 311, a gear 312 and a motor 313; the gear 312 is arranged on the output shaft of the motor 313, the rack 311 is connected to the plug-in assembly 32, and the gear 312 is adapted to mesh with the rack 311 to drive the plug-in assembly 32 to move along the first direction when the motor 313 rotates.

[0042] The first direction is the direction of a straight line in a horizontal position when the drone throwing device 1 is in use, as shown in the attached Figure 5 shown.

[0043] The motor 313 transmits the rotational force to the gear 312 through the shaft. When the motor 313 rotates, the gear 312 on the shaft will also rotate. There is meshing between the gear 312 and the rack 311, and the rotational force is transmitted to the rack 311 through the meshing surface of the gear 312, so that the rack 311 moves along the first direction. The gear 312 and the rack 311 have good guiding properties. The gear 312 and the rack 311 included in the transmission assembly 31 have good guiding properties. The rack 311 drives the gear 312 through the motor 313. After the gear 312 is transmitted to the rack 311, the rack 311 and the connected pin 322 can accurately move in the same direction and plug into the socket 411 of the throwing object 4. The control logic is simple and accurate. When the drone enters the air, the motor 313 drives the gear 312 to drive the rack 311 and the pin 322 to move in the first direction away from the socket 411 so as to separate from the socket 411, and the throwing object 4 can be easily separated from the drone throwing device 1. The drone throwing device 1 has a simple internal structure, can be easily operated during production and later maintenance, has a lower cost than drone throwing devices on the market, and is convenient for mass production.

[0044] The plug-in assembly 32 includes a main body 321 and a pin 322, the main body 321 and the pin 322 are in a connection relationship, a corresponding socket 411 is provided on the parabolic object 4, the pin 322 and the socket 411 are correspondingly plugged in to fix the parabolic object 4 on the shell 2, and, under the action of the transmission assembly 31, the pin 322 and the socket 411 are separated, so that the parabolic object 4 is separated from the shell 2.

[0045] The throwing mechanism 3 can be built inside the housing 2 or placed outside the housing 2, and it is sufficient to ensure that the rack 311 and the pin 322 can move along the first direction for insertion or separation. Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the throwing mechanism 3 is built into the shell 2. Specifically, the shell 2 can effectively protect the internal throwing mechanism 3, extend the service life of the drone throwing device 1, and prevent dust and foreign matter from entering the throwing mechanism 3 and causing malfunctions.

[0046] Specifically, the shell 2 has a cavity 21 inside, and the throwing mechanism 3 is arranged in the cavity 21; the throwing object 4 has a boss 41, and the socket 411 is arranged on the boss 41. The lower part of the shell 2 has a through hole 22 for the boss 41 to extend into the cavity 21. When the boss 41 is placed in the through hole 22, the socket 411 can be plugged with the pin 322.

[0047] like Figures 1 to 3 As shown, the shell 2 includes an upper shell portion 202 and a lower shell portion 201. The upper shell portion 202 and the lower shell portion 201 are split structures and are connected to form the shell 2 by snap-fitting or screws, forming a cavity 21 in the middle for installing the throwing mechanism 3.

[0048] The function of the boss 41 is to provide a connection point for the parachuting object 4 to connect to the drone throwing device 1. The boss 41 is provided with a socket 411 so that it can be plugged with the pin 322 and can also play a positioning role. The boss 41 cooperates with the through hole 22 of the lower part 201 of the shell to ensure that the boss 41 can accurately extend into the through hole 22 of the cavity 21 and is not easy to shake or deform during use. Specifically, when installing the parachuting object 4, the boss 41 on the parachuting object 4 extends into the cavity 21 through the through hole 22 of the lower part 201 of the shell, and the socket 411 on the boss 41 is aligned and plugged with the pin 322 to achieve the connection between the parachuting object 4 and the throwing mechanism 3. When the parachuting object 4 is thrown, the pin 322 moves in the first direction away from the socket 411 under the drive of the transmission assembly 31 and separates from the socket 411, so that the parachuting object 4 is thrown smoothly.

[0049] A raised outer wall 210 is provided on the periphery of the through hole 22, and the raised outer wall 210 is symmetrically arranged on the inner surface of the upper shell part 202 and the inner surface of the lower shell part 201. The raised outer wall 210 has a movable groove 23 for the column pin 322 to move, and the movable groove 23 is symmetrically arranged on the surface of the raised outer wall 210. When the upper shell part 202 and the lower shell part 201 are installed together to form the shell 2, the two movable grooves 23 are combined to form a limiting hole (not marked in the figure), which is used to guide the movement of the column pin 322 and provide a specific path for the movement of the column pin 322. The setting direction of the movable groove 23 is the same as the first direction.

[0050] When the pin 322 is connected to the socket 411, both ends abut against the groove wall of the movable groove 23. The gravity generated by the connected projectile 4 can be transmitted to the groove wall of the movable groove 23 through the pin 322 and then to the shell 2, thereby forming a stable insertion between the pin 322 and the socket 411. The height set of the movable groove 23 corresponds to the height of the pin 322, which facilitates the sliding insertion of the pin 322.

[0051] like Figure 2 As shown, the inner surface of the lower part 201 of the shell is provided with a rack guide groove 24 extending along the first direction, and the rack 311 is slidably installed in the rack guide groove 24; the shell 2 is provided with a motor mounting position 25, and the motor 313 is placed in the motor mounting position 25 accordingly; the rack guide groove 24 and the motor mounting position 25 are arranged side by side.

[0052] The rack guide groove 24 can guide and position the rack 311, so that the rack 311 can be accurately installed and slide on a fixed route, preventing the rack 311 from shaking or deviating during movement, while reducing the friction between the rack 311 and the housing 2, so that the rack 311 moves more smoothly. Figure 2 and Figure 3 As shown, the motor mounting position 25 is symmetrically arranged on the inner surface of the upper shell 202 and the surface of the lower shell 201, and the motor 313 is clamped between the upper and lower mounting seats to form a fixed position. The motor mounting position 25 is arranged inside the shell 2 to position the motor 313 so that it can be accurately connected and matched with the gear 312, and at the same time, it plays a certain protective role on the motor 313 to prevent external factors from causing damage to the motor 313.

[0053] The plug-in assembly 32 is also connected to a guide member 323 , which is connected to the body 321 . The inner surface of the lower portion 201 of the shell is provided with a corresponding guide groove 26 , in which the guide member 323 is slidably installed, and the guide groove 26 extends along the first direction.

[0054] The guide groove 26 and the guide member 323 are used together to guide and position the movement of the plug assembly 32, ensuring that it can be accurately inserted or removed, and can reduce the friction between the guide member 323 and the housing 2, so that the guide member 323 moves more smoothly. The guide groove 26 and the rack guide groove 24 form a double guide groove structure, and the guide groove 26 and the rack guide groove 24 are parallel. The design of the double guide groove structure helps to improve the guiding stability and reliability of the entire device, ensuring that the transmission assembly 31 and the plug assembly 32 are more accurate and stable during the movement.

[0055] The plug-in assembly 32 is also connected to a handle 34 , which is connected to the body 321 and can drive the pin 322 away from or close to the plug hole 411 .

[0056] The shell 2 is provided with an exposure hole 28, which is symmetrically arranged on the sides of the upper shell 202 and the lower shell 201 so that the handle 34 can be exposed outside the shell 2. The handle 34 serves as an interactive medium between the person and the drone throwing device 1, allowing the user to more intuitively perceive and control the state and operation of the plug-in component 32, which is convenient for the user to operate. Specifically, when installing the throwing object 4, the handle 34 drives the pin 322 to move to the end of the exposure hole 28 along the first direction away from the socket 411, and then the boss 41 of the throwing object 4 is placed in the through hole 22 of the lower shell 201, so that the socket 411 on the boss 41 is aligned with the pin 322. Similarly, the user can manually remove the installed throwing object 4 by toggling the handle 34 along the first direction away from the socket 411 to disconnect the pin 322 and the socket 411.

[0057] like Figure 5 and Figure 6 As shown, the casting mechanism 3 has a reset assembly 33, which includes a spring 331, a spring pin 332 connected to the body 321 and a spring blocking portion 333 arranged on the shell 2; one end of the spring 331 is at least partially sleeved on the outer periphery of the spring pin 332, and the other end is abutted against the spring blocking portion 333, so that the column pin 322 connected to the body 321 has a tendency to approach the socket 411.

[0058] In this embodiment, when the handle 34 is moved in the first direction away from the insertion hole 411 to the end of the exposed hole 28, one end of the spring 331 abuts against the spring pin 332, and the handle 34 drives the spring pin 332 to move so that the spring 331 is compressed, and one end abuts against the end surface of the spring blocking portion 333. The spring blocking portion 333 limits the spring 331, so that after the handle 34 is released, the spring 331 can stably apply a reset force to the column pin 322, so that the column pin 322 is inserted into the insertion hole 411, thereby realizing the connection between the thrown object 4 and the throwing mechanism 3. The spring pin 332 limits the spring 331 and guides the extension direction of the spring 331. The function of the spring blocking portion 333 is to ensure the stretched length of the spring 331 and avoid damage to the spring 331 due to excessive extension. The spring blocking portion 333 serves as a force point of the spring 331, so that when the handle 34 is released, the spring 331 generates a reset force in the first direction close to the insertion hole 411 on the plug assembly 32.

[0059] When installing the projectile 4, there are at least three ways to connect the pin 322 with the socket 411. One is to control the gear 312 to transmit the rotational force through the motor 313 and transmit it to the rack 311 through the meshing surface of the gear 312 to drive the pin 322 away from the limit hole, insert the boss 41 of the projectile 4 into the through hole 22, and then control the pin 322 to approach the socket 411 and plug it into the socket 411 through the motor 313; the other is that the user operates the handle 34 to make The pin 322 is moved away from the limiting hole, and the boss 41 of the projectile 4 is inserted into the through hole 22. Then, the handle 34 is operated to control the pin 322 to be close to the socket 411 and to be plugged into the socket 411. Another method is that the user operates the handle 34 to make the pin 322 move away from the limiting hole, and after the boss 41 of the projectile 4 is inserted into the through hole 22, the user releases the handle 34, and the reset force of the reset component 33 is used to make the pin 322 plug into the socket 411 to achieve connection with the projectile 4.

[0060] When separating the parachuting object 4 from the drone throwing device 1, there are at least two ways to separate the pin 322 from the socket 411: one is that when the drone is in the air, the remote control motor 313 controls the gear 312 to transmit the rotational force and transmits it to the rack 311 through the meshing surface of the gear 312 to drive the pin 322, so that the pin 322 leaves the socket 411, and the parachuting object 4 is disengaged from the through hole 22, thereby realizing the separation of the parachuting object 4 from the drone throwing device 1; the other is that the user operates the handle 34 on the ground to control the pin 322 to move away from the socket 411, and takes the parachuting object 4 out of the through hole 22, thereby realizing the separation of the parachuting object 4 from the drone throwing device 1.

[0061] In this embodiment, the above-mentioned various connection and separation methods of the drone throwing device 1 and the throwing object 4 are combined, and the multiple methods enhance the user experience, and the control principle is simple, and the user can operate it easily.

[0062] Specifically, the user operates the handle 34 to move the pin 322 away from the limiting hole, inserts the boss 41 of the parachuted object 4 into the through hole 22, and then releases the handle 34. The reset force of the reset assembly 33 causes the pin 322 to be plugged into the socket 411 to achieve connection with the parachuted object 4. Then the user releases the drone. When the drone is in the air, the remote control motor 313 controls the gear 312 to transmit the rotational force, which is transmitted to the rack 311 through the meshing surface of the gear 312 to drive the pin 322, so that the pin 322 leaves the socket 411, and the parachuted object 4 is disengaged from the through hole 22, thereby achieving the separation of the parachuted object 4 from the drone throwing device 1.

[0063] like Figure 7As shown, in this embodiment, the plug assembly 32, the spring pin 332, the handle 34, the rack 311 and the guide member 323 are an integrated structure, and the various components are extended outward from the main body 321. This structure reduces the connecting parts, thereby effectively reducing the risk of loosening and falling off of parts, making the entire structure more stable, and increasing the reliability of the product. At the same time, it also greatly simplifies the manufacturing process of the production link, effectively reducing the manufacturing cost and subsequent maintenance cost.

[0064] like Figure 1 As shown, the outer surface of the upper part 202 of the housing is provided with a connector 27 for matching with the drone, and the drone is aligned with the groove of the connector 27 and slidably inserted and matched to achieve the connection and fixation of the drone throwing device 1 and the drone. There is a drone limiting hole 29 at the center of the groove of the connector 27, which is used to match with the corresponding structure on the drone to ensure that the drone can be accurately connected to the drone throwing device 1 at a predetermined position during insertion, improve the accuracy of the connection, and further strengthen the stability after the connection to prevent the drone throwing device 1 from loosening or shifting during flight.

[0065] like Figure 3 As shown, the head of the pin 322 is processed into a rounded corner, and the purpose of processing into the rounded corner is to make it easier for the pin 322 to enter the insertion hole 411.

[0066] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
