[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] The following is for reference. Figures 1 to 7 This invention describes a drone launching device according to an embodiment of the present invention.

[0023] According to an embodiment of the present utility model, the drone launching device is referenced. Figures 1 to 7 As shown, it includes a launch tube 100, a gas storage section 200, a connecting section 300, a sealing assembly 400, and a bomb storage component 500.

[0024] The launch tube 100 can be cylindrical and has a launch cavity 101 for housing the drone. The launch cavity 101 can be cylindrical and extend along the axial direction of the launch tube 100. One end of the launch cavity 101 is the launch port, and the other end can be provided with an air inlet. The size of the air inlet can be smaller than the size of the launch cavity 101 to prevent the drone inside the launch cavity 101 from falling out.

[0025] The gas storage section 200 is provided with a gas storage chamber 201 and a vent 202 communicating with the gas storage chamber 201. The gas storage section 200 can be cylindrical or other suitable shapes. The gas storage chamber 201 is used to store compressed gas, such as nitrogen or other inert gases. The compressed gas in the gas storage chamber 201 can be discharged or enter through the vent 202.

[0026] The connecting part 300 is located between the launching tube 100 and the gas storage part 200. The connecting part 300 can be cylindrical or other suitable shapes. The connecting part 300 is provided with a connecting cavity 301, which can be connected to the launching cavity 101 through the air inlet of the launching cavity 101.

[0027] The sealing component 400 is located in the connecting cavity 301 and seals the vent 202. The bomb storage component 500 is located in the connecting cavity 301 and has a placement cavity 501 for placing the bomb. The placement cavity 501 of the bomb storage component 500 can be close to the sealing component 400. The bomb can be any common bomb. The bomb is used to destroy the sealing component 400. The bomb can completely destroy the sealing component 400 or partially destroy the sealing component 400. It is only necessary to release the seal on the vent 202 so that the connecting cavity 301 and the vent 202 are completely connected.

[0028] In this application, the gas storage chamber 201 of the gas storage unit 200 is filled with compressed gas, such as nitrogen or other inert gas. The UAV is then placed in the launch chamber 101 of the launch tube 100. After the bomb is detonated, the bomb can instantly destroy the sealing component 400, thereby instantly releasing the seal on the vent 202. This allows the connecting chamber 301 to be fully connected to the vent 202. The compressed gas in the gas storage chamber 201 can then quickly enter the launch chamber 101 through the vent 202 and the connecting chamber 301, thereby rapidly launching the UAV into the air and achieving the launch of the UAV.

[0029] The drone launching device according to the present invention is not only simple in structure and relatively inexpensive, but also allows the connecting cavity 301 and the vent 202 to be completely connected instantly by the bomb instantly destroying the sealing component 400. This allows more compressed gas to enter the launching cavity 101 more quickly, resulting in a faster response and a greater instantaneous thrust generated by the airflow, thereby significantly improving the launch speed of the drone.

[0030] refer to Figures 4 to 7 As shown, in some embodiments of this utility model, a mounting portion 302 is provided inside the communicating cavity 301, and the sealing assembly 400 includes a sealing portion 401 and a locking bolt 402. The sealing portion 401 abuts against the end of the vent 202 away from the air storage cavity 201 to seal the vent 202. The locking bolt 402 is threadedly connected to the mounting portion 302 and abuts against the side of the sealing portion 401 away from the vent 202. For example, the mounting portion 302 may be disc-shaped, with its outer peripheral wall connected to the inner peripheral wall of the communicating cavity 301. The mounting portion 302 may have a threaded hole, and the locking bolt 402 is threadedly connected to the threaded hole.

[0031] In this embodiment, the locking bolt 402 and the sealing part 401 cooperate to block the vent 202. The sealing assembly 400 has a simple structure and is easy to assemble. Moreover, the locking bolt 402 is connected to the mounting plate by threads, which keeps the sealing part 401 in a blocked state, resulting in a better sealing effect. In addition, the degree to which the sealing part 401 presses against the gas storage part 200 can be adjusted by rotating the locking bolt 402.

[0032] refer to Figures 5 to 7 As shown, in some embodiments of the present invention, the sealing assembly 400 further includes an abutment portion 403, which abuts against the side of the sealing portion 401 away from the vent 202, and a locking bolt 402 abuts against the side of the abutment portion 403 away from the sealing portion 401. A bomb is used to destroy the abutment portion 403.

[0033] In this embodiment, the abutment part 403 only abuts against the sealing part 401 and the locking bolt 402, and does not directly connect the sealing part 401 and the locking bolt 402. Therefore, it is easier for the abutment part 403 to be destroyed. After the abutment part 403 is destroyed, it is also easier for it to move out from between the sealing part 401 and the locking bolt 402, thereby releasing the abutment against the sealing part 401. Under the force of the compressed gas in the gas storage chamber 201, the sealing part 401 can release the blockage of the vent 202, thus allowing the gas storage chamber 201 to quickly connect with the connecting chamber 301. Furthermore, since the bomb only destroys the abutment part 403, it can reduce the impact on the gas storage part 200, for example, avoiding damage to the gas storage part 200, thus improving its practicality.

[0034] It is understandable that the contact part 403 can be made of a material that is relatively easy to be destroyed, such as thin steel, while the sealing part 401, the locking bolt 402 and the gas storage part 200 can be made of a material that is not easily destroyed, which will not be described in detail here.

[0035] It should be noted that in other embodiments of this utility model, the sealing component 400 may also have other structures, such as an integral cylindrical structure, in which the bomb storage component 500 can be directly inserted into the sealing component 400.

[0036] refer to Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the abutment part 403 is provided with a receiving hole 404, the locking bolt 402 is provided with an insertion hole 405 that extends along its own axial direction, the bomb storage component 500 passes through the insertion hole 405, and one end of the bomb storage component 500 forms a placement cavity 501 and extends into the receiving hole 404.

[0037] In this embodiment, the locking bolt 402 is provided with an insertion hole 405, which makes it easier to insert and install the bomb storage component 500. Moreover, the abutment part 403 is provided with a receiving hole 404. One end of the bomb storage component 500 with the placement cavity 501 extends into the receiving hole 404. In this way, the bomb can be directly located in the receiving hole 404 of the abutment part 403, thereby improving the effect of destroying the abutment part 403.

[0038] It should be noted that the bomb storage unit 500 can also be installed in other suitable ways, such as by using fasteners.

[0039] refer to Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the receiving hole 404 passes through the abutment portion 403 along the axial direction of the locking bolt 402, a first protrusion 406 is formed on the side of the sealing portion 401 near the locking bolt 402, and a second protrusion 407 is formed on the side of the locking bolt 402 near the sealing portion 401. The first protrusion 406 and the second protrusion 407 are respectively fitted and inserted into both ends of the receiving hole 404.

[0040] In this embodiment, the receiving hole 404 penetrates the abutment portion 403, and the first protrusion 406 of the blocking portion 401 and the second protrusion 407 of the locking bolt 402 are respectively inserted into the two ends of the receiving hole 404. In this way, the blocking portion 401 and the abutment portion 403 can be limited, preventing the blocking portion 401 and the abutment portion 403 from moving arbitrarily along the radial direction of the abutment portion 403. This makes the installation of the blocking portion 401 and the abutment portion 403 more stable and the sealing effect of the vent hole 202 better.

[0041] refer to Figure 6 and Figure 7As shown, in some embodiments of this utility model, the mounting part 302 is provided with a plurality of connecting holes 303, which are arranged circumferentially along the locking bolt 402 and penetrate the mounting part 302 axially along the locking bolt 402. For example, the mounting part 302 may be provided with three connecting holes 303, which are evenly arranged circumferentially along the locking bolt 402.

[0042] In this embodiment, the mounting part 302 is provided with multiple connecting holes 303 around the locking bolt 402. When the abutment part 403 is destroyed and the sealing part 401 releases the blockage of the vent 202, the compressed gas in the gas storage chamber 201 can quickly enter the launch chamber 101 of the launch tube 100 through the connection of the multiple connecting holes 303, avoiding gas blockage and thus making the launch effect of the UAV better.

[0043] refer to Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the side wall of the connecting part 300 is provided with a plurality of mounting holes 304, the mounting holes 304 are used to install anti-loosening bolts, and the anti-loosening bolts are used to abut against the side wall of the locking bolt 402.

[0044] In this embodiment, after the locking bolt 402 is installed, the anti-loosening bolt is installed in the mounting hole 304 and abuts against the side wall of the locking bolt 402. Through the friction between the anti-loosening bolt and the locking bolt 402, the locking bolt 402 can be prevented from rotating freely and becoming loose. Thus, before the bomb destroys the abutment part 403, the sealing effect of the sealing part 401 can be effectively prevented from decreasing and causing air leakage.

[0045] refer to Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the side wall of the connecting part 300 is provided with a wiring hole 305 for the lead wire or conductor connected to the bomb to run. For example, when the bomb is a bomb with a lead wire, the wiring hole 305 is used for the lead wire connected to the bomb to run; when the bomb is a bomb with a conductor that is detonated by electricity or communication, the wiring hole 305 is used for the conductor connected to the bomb to run, making the routing of the lead wire or conductor connected to the bomb more convenient and avoiding messy arrangement of the lead wire or conductor.

[0046] It should be noted that the reference Figure 7 As shown, the bomb storage unit 500 may be provided with a wiring channel 502 that connects to the housing cavity 501 to facilitate the routing of lead wires or conductors.

[0047] refer to Figure 3 and Figure 7As shown, in some embodiments of this utility model, the gas storage unit 200 is provided with an air inlet 203 that connects to the vent 202 or the gas storage chamber 201, and the air inlet 203 is provided with a one-way valve. In this embodiment, the gas storage unit 200 is provided with an air inlet 203, which can be used to connect to an external inflation device. The air inlet 203 is provided with a one-way valve, which allows gas to enter the gas storage chamber 201 and restricts the gas in the gas storage chamber 201 from being discharged from the air inlet 203.

[0048] refer to Figure 3 , Figures 5 to 7 As shown, in some embodiments of this utility model, the gas storage section 200 is provided with a gas outlet 204 that connects to the vent 202 or the gas storage chamber 201, and the gas outlet 204 is provided with a pressure relief valve. When there is too much gas in the gas storage chamber 201 and the gas pressure exceeds the preset value, the pressure relief valve is activated to release some gas, thereby preventing the gas pressure in the gas storage chamber 201 from becoming too high and causing an explosion, thus improving safety.

[0049] refer to Figure 1 As shown, in some embodiments of this utility model, the drone launching device further includes a support frame 600, which is connected to the launching tube 100 and is used to support the drone on the ground. When the drone launching device of this embodiment is placed on the ground, it can be supported by the support frame 600, thereby making the launching tube 100 tilt upward relative to the ground, making it more convenient to launch the drone.

[0050] It should be noted that in some other embodiments of this utility model, the drone launcher can also be vehicle-mounted and directly installed on a vehicle via an installation structure. In this case, there is no need to set up a support frame 600.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
