Description

Technical Field

[0001] This utility model relates to the field of drone bombing technology, specifically a drone bombing fixing device. Background Technology

[0002] Currently, drones are equipped with drop devices to deliver items, such as airdropping supplies to areas inaccessible by ground transportation. However, these devices are generally only suitable for airdropping general supplies, and they are complex in structure and have a relatively high failure rate. In some special fields, such as military, firefighting, police, or criminal investigation, drones are needed to perform bombing missions. Depending on the mission objective, different types of munitions are typically used, including gas bombs, fire extinguishing bombs, smoke bombs, and signal flares. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drone bomb-dropping fixing device to address the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A drone bomb-dropping fixing device includes a housing, a first clamping mechanism, a second clamping mechanism, and an auxiliary fixing mechanism. Multiple first clamping mechanisms are provided inside the housing, each used to clamp vertically placed standard ammunition. Multiple mounting holes, each adapted to one of the first clamping mechanisms, are provided at the bottom of the housing. A second clamping mechanism is also provided inside the housing, with its clamping claws extending through and to the bottom of the housing, used to clamp horizontally placed standard ammunition. An auxiliary fixing mechanism is provided at the bottom of the housing to assist the second clamping mechanism in clamping and fixing the ammunition. A connecting plate is provided at the top of the housing for fixed connection with the drone, and the connecting plate is fixedly connected to the drone by bolts.

[0006] Furthermore, the first clamping mechanism includes a first motor, positioning posts, an upper mounting plate, a lower mounting plate, a clamping plate, and a gear transmission mechanism. Multiple positioning posts are radially evenly distributed around the mounting hole on the inner side of the housing. A rotating shaft is rotatably mounted on the inner side of each positioning post along its axis. An upper mounting plate and a lower mounting plate are horizontally positioned above the mounting hole on the inner side of the housing. A gear transmission mechanism is located between the upper and lower mounting plates. The gear transmission mechanism has multiple output ends, each rotatably connected to a rotating shaft. A first motor for driving the gear transmission mechanism is located at the top of the upper mounting plate. The rotating shaft is vertically positioned within a through hole in the middle of the positioning post. A rotating groove connected to the through hole is opened on the lower side of the positioning post. A clamping plate, which is fixedly connected to the rotating shaft, is horizontally positioned inside the rotating groove. The clamping plate is used to clamp standard ammunition placed vertically within the mounting hole. The first motor drives the gear transmission mechanism to rotate, causing multiple rotating shafts and the clamping plate to rotate synchronously and in the same direction to clamp or release the standard ammunition.

[0007] Furthermore, the second clamping mechanism includes a second motor, a forward and reverse threaded rod, a moving block, a connecting rod, and clamping claws. The forward and reverse threaded rod is horizontally arranged inside the housing. The second motor is installed at one end of the forward and reverse threaded rod. Two moving blocks are symmetrically arranged on the forward and reverse threaded rod, respectively located at the forward and reverse threaded sections. Two clamping claws are symmetrically arranged on the inside of the housing, respectively located at the outer ends of the two ends of the forward and reverse threaded rod. Both clamping claws are rotatably connected to the housing. Each of the two moving blocks is rotatably connected to a connecting rod, the other end of which is rotatably connected to the two clamping claws. The second motor is used to drive the forward and reverse threaded rod to rotate, causing the two moving blocks to move away from or closer to each other. Then, the connecting rod drives the clamping claws to clamp or release horizontally placed standard ammunition. The clamping surface of the clamping claws is also provided with rubber strips.

[0008] Furthermore, the auxiliary fixing mechanism includes a positioning box, an elastic sheet, a push plate, a push rod, and a compression plate. The positioning box is provided at the bottom of the housing, and a push plate is provided inside the positioning box. A push rod extending through to the bottom of the positioning box is provided at the bottom of the push plate. A compression plate for compressing the top of the standard ammunition is provided at the bottom of the push rod. An elastic sheet is provided inside the positioning box. The middle part of the horizontally placed standard ammunition held by the second clamping mechanism is located below the compression plate. The elastic sheet is used to push the compression plate downward to compress the middle part of the standard ammunition through the push plate and push rod, and to cooperate with the clamping claw to fix the standard ammunition.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This invention, by setting up a first clamping mechanism and a second clamping mechanism, can respectively clamp vertically and horizontally placed standard ammunition, such as gas grenades, fire extinguishing grenades, smoke grenades, and signal flares, meeting the deployment requirements of different ammunition types and enhancing the adaptability and flexibility of the device. The first clamping mechanism, through the cooperation of a gear transmission mechanism and a motor, realizes the synchronous rotation of multiple clamping plates, effectively clamping and releasing ammunition, with a compact structure and efficient operation. The second clamping mechanism utilizes a positive and negative threaded rod and linkage structure, which can realize the rapid opening and closing of the clamping claws through motor drive, making operation simple and reliable. The auxiliary fixing mechanism, through the cooperation of components such as elastic plates, push plates, and push rods, can provide additional compressive force from the top of the ammunition while the clamping claws are holding it, ensuring the stability of the ammunition before deployment and reducing the risk of accidents during deployment.

[0023] like Figures 1-7 As shown, a drone bomb-dropping fixing device includes a housing 1, a first clamping mechanism 2, a second clamping mechanism 3, and an auxiliary fixing mechanism 4. Multiple first clamping mechanisms 2 are provided inside the housing 1, used to clamp vertically placed standard ammunition. Multiple mounting holes 6, each adapted to one of the first clamping mechanisms 2, are provided at the bottom of the housing 1. A second clamping mechanism 3 is also provided inside the housing 1, with clamping claws 305 penetrating and extending to the bottom of the housing 1, used to clamp horizontally placed standard ammunition. An auxiliary fixing mechanism 4 is provided at the bottom of the housing 1 to assist the second clamping mechanism 3 in clamping and fixing. A connecting plate 5 is provided at the top of the housing 1 for fixed connection with the drone, and the connecting plate 5 is fixedly connected to the drone by bolts.

[0024] In one embodiment, the first clamping mechanism 2 includes a first motor 201, positioning posts 202, an upper mounting plate 203, a lower mounting plate 204, a clamping plate 205, and a gear transmission mechanism 206. Multiple positioning posts 202 are radially and evenly distributed around the mounting hole 6 on the inner side of the housing 1. A rotating shaft is rotatably mounted on the inner side of each positioning post 202 along its axis. An upper mounting plate 203 and a lower mounting plate 204 are horizontally positioned above the mounting hole 6 on the inner side of the housing 1. A gear transmission mechanism 206 is provided between the upper mounting plate 203 and the lower mounting plate 204. The gear transmission mechanism 206 has multiple output ends, each... Each output end is rotatably connected to a rotating shaft. The top of the upper mounting plate 203 is provided with a first motor 201 for driving the gear transmission mechanism 206 to rotate. The rotating shaft is vertically installed in the through hole in the middle of the positioning post 202. The lower side of the positioning post 202 is provided with a rotating groove connected to the through hole. A clamping plate 205 is horizontally installed inside the rotating groove and can be fixedly connected to the rotating shaft. The clamping plate 205 is used to clamp the standard ammunition placed vertically in the mounting hole 6. The first motor 201 is used to drive the gear transmission mechanism 206 to rotate, thereby driving multiple rotating shafts and clamping plates 205 to rotate synchronously and in the same direction to clamp or release the standard ammunition.

[0025] In one embodiment, the second clamping mechanism 3 includes a second motor 301, a forward and reverse threaded rod 302, a moving block 303, a connecting rod 304, and a clamping claw 305. The forward and reverse threaded rod 302 is horizontally arranged inside the housing 1. The second motor 301 is located at one end of the forward and reverse threaded rod 302. Two moving blocks 303 are symmetrically arranged on the forward and reverse threaded rod 302, respectively located on the forward and reverse threaded sections. The outer sides of the forward and reverse threaded rod 302 are symmetrically arranged inside the housing 1. Two clamping claws 305 on the side are rotatably connected to the housing 1. Each of the two moving blocks 303 is rotatably connected to a connecting rod 304, the other end of which is rotatably connected to the two clamping claws 305 respectively. The second motor 301 is used to drive the positive and negative threaded rods 302 to rotate, so that the two moving blocks 303 move away from or closer to each other. Then, the connecting rods 304 drive the clamping claws 305 to clamp or release the horizontally placed standard ammunition. The clamping surface of the clamping claws 305 is also provided with rubber strips 7.

[0026] In one embodiment, the auxiliary fixing mechanism 4 includes a positioning box 401, an elastic sheet 402, a push plate 403, a push rod 404, and a compression plate 405. The positioning box 401 is provided at the bottom of the housing 1. The push plate 403 is provided inside the positioning box 401. The push rod 404, which extends through to the bottom of the positioning box 401, is provided at the bottom of the push plate 403. The compression plate 405, which is used to compress the top of the standard ammunition, is provided at the bottom of the push rod 404. The elastic sheet 402 is provided inside the positioning box 401. The middle part of the horizontally placed standard ammunition held by the second clamping mechanism 3 is located below the compression plate 405. The elastic sheet 402 is used to push the compression plate 405 downward to compress the middle part of the standard ammunition through the push plate 403 and the push rod 404, so as to fix the standard ammunition in conjunction with the clamping claw 305.

[0027] In this utility model, a storage battery is also provided inside the housing 1.

[0028] The working process of this utility model is as follows: For ammunition that needs to be placed vertically, the first motor 201 is started to rotate forward, driving multiple rotating shafts to rotate synchronously through the gear transmission mechanism 206, thereby driving the clamping plate 205 to rotate and clamp the ammunition. The rotation angle and force of the clamping plate 205 can be adjusted through the design of the gear transmission mechanism 206 to ensure that the ammunition is firmly clamped. When it is necessary to release the ammunition, the first motor 201 rotates in reverse, causing the multiple clamping plates 205 to rotate in the opposite direction to release the ammunition.

[0029] For ammunition that needs to be placed horizontally, the second motor 301 is activated to rotate forward, driving the forward and reverse threaded screw 302 to rotate. The two moving blocks 303 on the forward and reverse threaded screw 302 move closer or further apart under the drive of the screw, causing the clamping claws 305 to close via the connecting rod 304, thus clamping the ammunition. The rubber strip 7 increases the friction between the clamping claws 305 and the ammunition surface. Simultaneously, the elastic plate 402 of the auxiliary fixing mechanism 4 pushes the compression plate 405 to compress the top of the standard ammunition via the push plate 403 and push rod 404, further enhancing clamping stability. When the ammunition needs to be released, the second motor 301 rotates in the reverse direction, causing the clamping claws 305 to open, and the ammunition automatically falls and is released.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
