Description

Technical Field

[0001] This utility model belongs to the field of external mounting equipment, specifically relating to a quick-release structure for external mounting equipment of unmanned aerial vehicles. Background Technology

[0002] As a composite equipment combining "aerial platform and mission payload," the core value of unmanned aerial vehicles (UAVs) lies in their ability to perform diverse operations such as aerial surveying and mapping, agricultural plant protection, power line inspection, and emergency rescue by carrying external devices with different functions. With the popularization of UAV technology, the efficiency of assembling and disassembling externally mounted equipment, its compatibility, and the reliability of its connections have become key bottlenecks restricting the operational flexibility and scenario expansion capabilities of UAVs.

[0003] In existing technologies, the method of fixing externally mounted equipment is selected according to the weight and type of the equipment. Light equipment (such as miniature cameras) is tied to the drone bracket with nylon straps, while medium and heavy equipment (such as lidar and agricultural spray nozzles) are rigidly connected to the drone body with bolts. Some require calibration of the equipment's center of gravity to ensure flight balance. The mounted equipment is connected to the drone's power interface and data interface through independent cables to achieve power supply and data transmission.

[0004] To maintain the stability of the mounted equipment, the external mounted equipment of the drone is usually fixed with screws and other fasteners. Since there are many types of airborne avionics equipment and equipment needs to be replaced frequently, it is quite cumbersome to disassemble and replace them with a traditional screwdriver during outdoor operations. There is also the possibility of losing screws, which leads to the problem of complicated disassembly and assembly. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-release structure for external attachment equipment of drones. By pressing the stop block, the spring is compressed until the upper end face is flush with the mounting plate. Then, the attachment is placed on the upper end of the mounting plate. By moving it horizontally to the left, the locking block is inserted into the storage box, thereby limiting the vertical direction of the attachment. After releasing the stop block, the spring causes the stop block to reset and limit the right end face of the attachment. This can effectively fix the attachment and achieve quick assembly and disassembly.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The quick-release structure for external mounting equipment of a drone includes a mounting plate; it also includes a first fixing plate and a locking component; the first fixing plate is fixedly connected to the lower end of the mounting plate, and two fixing posts are fixedly connected to the upper end of the first fixing plate. Springs are sleeved on the outer walls of the fixing posts. A first groove is opened through the upper end of the mounting plate, and a stop block is slidably arranged on the inner wall of the first groove. The lower end of the stop block is fixedly connected to the spring. A mount is slidably arranged on the upper end of the mounting plate, and a locking component is provided at the lower end of the stop block.

[0008] In one alternative embodiment, the spring height is greater than the fixed post, the stop is located at the right end of the load, and the upper end surface of the stop is higher than the upper end surface of the mounting plate.

[0009] In one optional embodiment, the drone body is fixedly attached to the lower end of the mounting plate, and multiple storage boxes are fixedly attached to the upper edge of the mounting plate. Multiple clips are fixedly attached to the outer wall of the mount, and the clips are adapted to the storage boxes.

[0010] In one optional embodiment, the locking component includes a connecting block, the right end of the mounting plate is fixed to the connecting block, and the upper end of the connecting block has a second groove extending through it.

[0011] In one optional embodiment, a slider is slidably disposed on the inner wall of the second tank, a connecting plate is fixedly connected to the lower end of the slider, and a limit protrusion is fixedly connected to the upper end of the connecting plate.

[0012] In one optional embodiment, the lower end of the connecting block is provided with multiple limiting grooves, the limiting protrusion is adapted to the limiting grooves, and the left end of the slider is fixedly connected to a limiting baffle.

[0013] In one optional embodiment, the upper end face of the limiting baffle is in contact with the lower end face of the stop block, and a second fixing plate is provided at the right end of the connecting block. The second fixing plate is fixedly connected to the connecting block by a fastener.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Press the stop block to compress the spring until the upper end is flush with the mounting plate. Then place the hanging object on the upper end of the mounting plate. Move it horizontally to the left to make the locking block engage inside the storage box, thereby limiting the vertical direction of the hanging object. Then release the stop block. Under the action of the spring, the stop block will reset and limit the right end of the hanging object, thus effectively fixing the hanging object and achieving quick assembly and disassembly.

[0016] 2. The locking state is switched by the cooperation of the limiting protrusion and the limiting groove; the connecting plate increases the connection strength between the slider and the limiting protrusion to ensure the structural stability when locked. After the limiting protrusion is inserted into the limiting groove, the limiting baffle blocks the block from moving down, thereby locking the position of the block. The fit design of the limiting baffle and the block can effectively transmit the locking force to ensure reliable locking and avoid the problem of the attached object falling off and damaging the equipment due to accidental touch or vibration during the use of the drone body.

[0028] Please see Figures 1-6 This utility model provides an embodiment of a quick-release structure for an external mount device for a drone, including a mounting plate 1; it also includes a first fixing plate 101 and a locking assembly; the lower end of the mounting plate 1 is fixedly connected to the first fixing plate 101, and the upper end of the first fixing plate 101 is fixedly connected to two fixing posts 102. A spring 103 is sleeved on the outer wall of each fixing post 102. A first groove 104 is formed through the upper end of the mounting plate 1, and a stop 105 is slidably disposed on the inner wall of the first groove 104. The lower end of the stop 105 is fixedly connected to the spring 103. A mount 106 is slidably disposed on the upper end of the mounting plate 1, and a locking assembly is provided at the lower end of the stop 105. Pressing the stop 105 compresses the spring 103. 3. Continue until the upper surface is flush with the mounting plate 1. Then place the hanger 106 on the upper end of the mounting plate 1. Move it horizontally to the left to make the locking block 4 engage inside the storage box 3, thereby limiting the vertical direction of the hanger 106. Then release the stop block 105. Under the action of the spring 103, the stop block 105 will be driven to reset and limit the right end of the hanger 106. This can effectively fix the hanger 106 and achieve quick disassembly and assembly. This solves the problem that since there are many types of airborne avionics equipment, and equipment needs to be changed frequently, it is quite cumbersome to disassemble and replace them with a traditional screwdriver when working outdoors. There is also the possibility of losing screws, which makes the disassembly and assembly process cumbersome.

[0029] Please see Figures 1-3In this embodiment, the height of the spring 103 is greater than that of the fixed post 102, the stop block 105 is located at the right end of the mount 106, and the upper surface of the stop block 105 is higher than the upper surface of the mounting plate 1. The lower end of the mounting plate 1 is fixedly connected to the drone body 2, and multiple storage boxes 3 are fixedly connected to the upper edge of the mounting plate 1. Multiple locking blocks 4 are fixedly connected to the outer wall of the mount 106. The locking blocks 4 are adapted to the storage boxes 3. The height of the spring 103 is greater than that of the fixed post 102, thereby ensuring that the stop block 105 can limit the mount 106 when it is in the reset state. The stop block 105 is located at the right end of the mount 106 and can block the mount 106 from sliding from the side. Together with the storage box 3 at the upper end of the mounting plate 1, it forms a two-way fixation. The distribution design of multiple locking blocks 4 and storage boxes 3 makes the mount 106 evenly stressed, improves the stability and balance of the connection, and avoids the drone's flight attitude being affected by the offset of the mount 106.

[0030] Please see Figures 2-6 In this embodiment, the locking component includes a connecting block 201. The connecting block 201 is fixedly connected to the right end of the mounting plate 1. A second groove 202 is formed through the upper end of the connecting block 201. A slider 203 is slidably disposed on the inner wall of the second groove 202. A connecting plate 204 is fixedly connected to the lower end of the slider 203. A limiting protrusion 205 is fixedly connected to the upper end of the connecting plate 204. A plurality of limiting grooves 206 are formed at the lower end of the connecting block 201. The limiting protrusion 205 is adapted to the limiting grooves 206. A limiting baffle 207 is fixedly connected to the left end of the slider 203. The upper end surface of the limiting baffle 207 is in contact with the lower end surface of the baffle 105. A second fixing plate 208 is provided at the right end of the connecting block 201. The second fixing plate 208 is fixed to the connecting block 201 by a fixing member. The slider 203 slides within the second groove 202, which drives the connecting plate 204 and the limiting protrusion 205 to move synchronously. The locking state is switched through the cooperation of the limiting protrusion 205 and the limiting groove 206. The connecting plate 204 increases the connection strength between the slider 203 and the limiting protrusion 205, ensuring structural stability during locking. After the limiting protrusion 205 is engaged in the limiting groove 206, the limiting baffle 207 blocks the block 105 from moving downward, thereby locking the position of the block 105. The fitting design of the limiting baffle 207 and the block 105 can effectively transmit the locking force, ensuring reliable locking and avoiding the problem of the attached object 106 detaching and damaging the equipment due to accidental touch or vibration during the use of the UAV body 2.

[0031] In use, first press the stop block 105 to compress the spring 103 until the upper end face is flush with the mounting plate 1. Then place the hanging object 106 on the upper end of the mounting plate 1. Move it horizontally to the left to make the locking block 4 lock into the storage box 3, thereby limiting the vertical direction of the hanging object 106. Then release the stop block 105. Under the action of the spring 103, the stop block 105 will be driven to reset and limit the right end face of the hanging object 106, thereby effectively fixing the hanging object 106 and realizing quick assembly and disassembly.

[0032] Then, by pushing the slider 203 to the left, the limiting baffle 207 moves to the lower end of the stop block 105, preventing the stop block 105 from moving downward. At this time, the limiting protrusion 205 matches the innermost limiting groove 206, keeping the slider 203 in a stable locked state. This prevents the mounted object 106 from detaching and damaging the equipment due to accidental touch or vibration during the use of the drone body 2. The second fixing plate 208 is fixedly connected to the connecting block 201 by the fixing component, which facilitates the maintenance and replacement of the slider 203.

[0033] Through the above steps, by pressing the stop block 105 to compress the spring 103 until the upper end face is flush with the mounting plate 1, the hanger 106 is placed on the upper end of the mounting plate 1. By moving it horizontally to the left, the locking block 4 is inserted into the storage box 3, thereby limiting the vertical direction of the hanger 106. Then, the stop block 105 is released, and under the action of the spring 103, the stop block 105 is driven to reset, limiting the right end face of the hanger 106. This can effectively fix the hanger 106 and achieve quick disassembly and assembly. This solves the problem that since there are many types of airborne avionics equipment, and equipment needs to be changed frequently, it is quite cumbersome to disassemble and replace them with a traditional screwdriver when working outdoors, and there is also the possibility of losing screws, which makes the disassembly and assembly process cumbersome.

[0034] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0035] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
