Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a quick-release bracket structure for UAV fire extinguishing bombs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are aircraft managed by a control station (including remote control or autonomous flight). With the rapid development of modern society, the number and height of high-rise buildings are constantly increasing, leading to a sharp increase in the pressure on fire rescue. UAV fire extinguishing bombs are a technical means of extinguishing fires by using UAVs to carry fire extinguishing bombs. The UAV flies to a suitable position above the fire source and releases the fire extinguishing bomb. During its flight in the air, the fuse is activated, and the bomb explodes upon impact with the fire source, releasing a large amount of fire extinguishing substances such as carbon dioxide, which isolates oxygen, thereby achieving the purpose of extinguishing the fire. The UAV needs to carry the fire extinguishing bombs through a rack, which is one of the important components of realizing UAV fire extinguishing bombs.

[0003] Currently, the use of drone fire extinguishing bomb mounts lacks a rotating quick-release structure. Typically, the mount structure is relatively simple and horizontally installed, requiring manual locking and unlocking, which is cumbersome and increases reloading time, affecting the efficiency of drone fire extinguishing operations. Therefore, a quick-release mount structure for drone fire extinguishing bombs is proposed to incorporate a rotating quick-release mechanism. This rotating assembly method replaces the traditional horizontal installation, while the inclined self-locking mechanism provides self-locking fixation, improving the flexibility and convenience of reloading operations and thus enhancing the overall effectiveness. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a quick-release bracket structure for drone fire extinguishing bombs, which allows for rotational assembly instead of traditional horizontal installation, thereby improving the effectiveness of use.

[0005] The technical solution adopted by this utility model to solve its technical problem is a quick-release bracket structure for a drone fire extinguishing bomb, including a bracket assembly and a servo motor mounting assembly, wherein the servo motor mounting assembly is provided at the bottom of the bracket assembly;

[0006] The bracket assembly includes a fixed frame, the bottom of which is fixedly connected to an extension section by screws. One end of the extension section is connected to a female connector by screws, and a male connector is inserted into the bottom of the female connector. One end of the female connector is provided with a quick-release head corresponding to the male connector.

[0007] By adopting the above technical solution, a rotating quick-assembly structure can be added, using rotation, splicing, and assembly to replace the traditional horizontal installation structure, thereby increasing the speed of secondary loading of fire extinguishing bombs.

[0008] Specifically, the servo mounting assembly includes a servo bracket, and the bottom of the male end is connected to the servo bracket by screws. A servo crossbar is connected to the outside of the servo bracket by screws, and both ends of the servo crossbar are connected to servo protective covers by screws.

[0009] By adopting the above technical solution, it is convenient to fix the servo motor for drone bombing operations.

[0010] Specifically, the quick-release interface of the male connector is a ramp type.

[0011] By adopting the above technical solution, it is possible to prevent the quick-release head from falling off during the operation of the drone.

[0012] The beneficial effects of this utility model are:

[0013] The present invention discloses a quick-release mounting structure for fire extinguishing bombs on drones. Through the setting of a fixed frame, an extension section, a male head, a female head, and a quick-release head, it can add a rotating quick-installation structure. By using rotation, splicing, and assembly, it replaces the traditional horizontal installation. This not only improves the speed of secondary loading of fire extinguishing bombs and shortens the operation time, but also uses a sloped self-locking mechanism to achieve self-locking fixation, thereby improving the stability of drones carrying fire extinguishing bombs.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] To facilitate rotational assembly instead of traditional horizontal installation, thereby improving usability, such as... Figure 1-3As shown, the quick-release bracket structure for a drone fire extinguishing bomb of this utility model includes a bracket assembly 1 and a servo motor mounting assembly 2, wherein the servo motor mounting assembly 2 is provided at the bottom of the bracket assembly 1.

[0021] The hanging bracket assembly 1 includes a fixing frame 101. The bottom of the fixing frame 101 is fixedly connected to an extension section 102 by screws. One end of the extension section 102 is connected to a female head 103 by screws. A male head 104 is inserted into the bottom of the female head 103. One end of the female head 103 is provided with a quick-release head 105 corresponding to the male head 104.

[0022] In use, the fixed frame 101, extension section 102, female head 103, male head 104 and quick-release head 105 can be used to add a rotating quick-release structure, which replaces the traditional horizontal installation structure by rotating, connecting and assembling, thereby improving the speed of secondary loading of fire extinguishing bombs.

[0023] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a servo mounting assembly 2 comprising a servo bracket 201, and the bottom of the male head 104 is connected to the servo bracket 201 by screws. A servo crossbar 202 is connected to the outside of the servo bracket 201 by screws. Both ends of the servo crossbar 202 are connected to servo protective covers 203 by screws.

[0024] In use, the servo motor bracket 201, servo motor crossbar 202 and servo motor protective cover 203 facilitate the fixed installation of the servo motor for UAV bombing operations. The servo motor crossbar 202 is made of carbon fiber.

[0025] For example, such as Figure 2 As shown, the present invention also includes a ramp-type quick-release interface for the male connector 104.

[0026] When in use, the ramp-type quick-release interface of the male head 104, with the addition of a protrusion, can prevent the quick-release head 105 from falling off during the operation of the drone.

[0027] For example, such as Figure 2 As shown, the present invention also includes a laser calibrator mounting bracket 204 connected to the outer side of the servo crossbar 202 by screws, and a PCB mounting compartment 3 connected to the bottom of the servo bracket 201 by screws.

[0028] In use, the laser calibrator is easily fixed and installed using the laser calibrator mounting bracket 204 for fire extinguishing grenade auxiliary throwing operations, and the PCB mounting compartment 3 is easily fixed and installed for use.

[0029] For example, such as Figure 1As shown, the present invention also includes a fire extinguishing bomb 4 at the bottom of the servo motor mounting assembly 2, and a hook 5 at the top of the fire extinguishing bomb 4.

[0030] When in use, the fire extinguishing bomb 4 and hook 5 are easily mounted on the servo motor so that the servo motor can operate to drop the bomb for fire extinguishing.

[0031] In use, the mounting bracket 101 is first fixedly installed on the drone with screws. Then, the extension section 102 is inserted into the bottom of the mounting bracket 101 and fixed together with it on the drone. The extension section 102 in the middle can allow the fire extinguishing bomb 4 to avoid the battery compartment on the belly of the drone. The lower end of the extension section 102 is the mounting section, which is divided into a male head 104 and a female head 103. After the extension section 102 is inserted into the mounting bracket, the female head 103 is fixedly installed at the end of the extension section 102 with screws. The servo bracket 201 at the bottom of the male head 104 is fixedly connected to the servo crossbar 202 and the servo protective cover 203 for mounting the servo. The data cable and power cable are connected from the carrier to the PCB fixing compartment 3 at the bottom of the servo bracket 201 through the extension section 102 and the mounting end. Then, the servo is controlled by the aircraft remote control to rotate and release the hook 5, thereby controlling the order of dropping the fire extinguishing bomb 4.

[0032] After the male connector 104 is fitted onto the female connector 103, it is fixed by rotating and falling back. The sloping quick-release interface of the female connector 103, with the addition of a protrusion, can prevent the quick-release connector 105 from falling off during the operation of the UAV. In addition, the rotating quick-release structure not only replaces the traditional horizontal installation method, but also replaces the traditional slot or buckle safety mechanism with a sloping self-locking mechanism. Since the quick-connect contact point is an inward single sloping surface, the male connector 104 of the bracket and the weight of the fire extinguishing bomb can achieve self-locking fixation. Even if there is slight slippage, the self-locking fixation can be completed under the influence of UAV flight vibration and its own weight. This eliminates the cumbersome steps of manual locking and unlocking in the traditional way, and greatly improves the convenience and flexibility of the secondary loading operation.
