Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV launching and mounting device. Background Technology

[0002] With the rapid development of drone technology, drones are used in many scenarios such as maritime rescue, high-altitude transportation, urban food delivery, and police security, all of which involve the loading and delivery of supplies. As a flight platform, drones need to carry different loads to cope with different applications in different fields. Facing complex and ever-changing operating environments, and constrained by the stringent requirements of drone flight endurance and takeoff weight, reducing the weight of the unloaded fuselage has always been an important consideration in drone design. Especially when designing large payloads, conventional designs suffer from uneven force distribution between carbon fiber and metal structures, which often leads to the failure of the connecting bolts of the mounting structure one by one from the point of maximum stress, greatly shortening the service life of the structure. Therefore, it is essential to improve the stress condition of the mounting structure while enabling rapid installation and disassembly.

[0003] For example, a drone throwing device (publication number: CN218172593U) includes a throwing frame, a throwing hook, an electromagnetic lock, a controller, and a power supply. The electromagnetic lock is installed on the top of the throwing frame. The bottom of the throwing hook is hinged to the throwing frame, and one end of the throwing hook extends to the locking hook of the electromagnetic lock and is hooked by the locking hook of the electromagnetic lock. The other end of the throwing hook is used to hang the thrown object. The controller includes a main control module, a photosensitive sensor, and a light shield. The photosensitive sensor is installed inside the light shield, and the light shield is installed on the drone's LED light. The main control module is used to control the operation of the electromagnetic lock. The photosensitive sensor is used to sense the drone's LED light to trigger a signal and transmit it to the main control module. The electromagnetic lock, the photosensitive sensor, and the power supply are all electrically connected to the main control module. This utility model has a simple structure, is lightweight, low in cost, and has a sensitive throwing response.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is known that the aforementioned equipment suffers from uneven force distribution during application. Although the hinged design of the throwing hook and throwing frame is flexible, it may also have insufficient stability. In complex environments such as high-speed flight or strong winds, the throwing hook may be subjected to additional forces and shake, thereby affecting the accuracy and safety of the throwing. Therefore, we need to propose a drone throwing and mounting device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A drone launching and mounting device includes a grid beam structure component 1, a mounting plate component 2, and a launching component 3. The mounting plate component 2 is mounted on the grid beam structure component 1. The mounting plate component 2 includes a mounting plate 202. Six sets of hooks 201 are fixedly installed on one side surface of the mounting plate 202. The back of the mounting plate 202 is designed with threaded through holes and micro-structure positioning holes. The top of the hooks 201 is designed with threads and micro-protrusion positioning structures. A cam locking component 203 is installed between one set of hooks 201 and the mounting plate 202. An L-shaped locking pin 204 is provided between the cam locking component 203 and the hooks 201.

[0028] The throwing assembly 3 includes a PCB potting protective cover 301, inside which a PCB module 302 is installed. A reset button 306 is glued into a pre-drilled hole on the side of the PCB potting protective cover 301. A silicone sealing ring 308 is installed in a pre-drilled hole on one side of the reset button 306 in the PCB potting protective cover 301. A sheet metal connector 303 is fixedly installed on one side of the PCB potting protective cover 301. A load hook 307 is installed on the bottom of the sheet metal connector 303 by a rivet. A servo motor 304 is installed on one side of the sheet metal connector 303 through a pre-drilled threaded hole.

[0029] This implementation example Figure 2 As shown, the grid beam structure component 1 includes two sets of span beams 101. The top of the two sets of span beams 101 is fixed with two sets of hanging beams 102 by bolts. The bottom of the hanging beams 102 is fixed with three sets of U-shaped buckles 103 by bolts. The two ends of the span beams 101 are assembled to the carbon fiber load-bearing frame of the UAV body by load-bearing bolts. The two ends of the hanging beams 102 are pressed against the span beams 101 from top to bottom by end faces and fixed in position by nuts. The U-shaped buckles 103 are designed with threaded holes on both sides. The upper part of the hanging beams 102 is designed with bolt mounting grooves. The bolts pass through the grooves from the top and are screwed into the threaded holes of the U-shaped buckles 103 to fasten them to the hanging beams 102. The bolts only serve to fix and limit the position, avoiding the risk of bolt failure under heavy load.

[0030] This implementation example Figure 2 As shown, six sets of U-shaped buckles 103 are evenly distributed on two sets of hanging beams 102, and a load-bearing bolt connection point is provided in the middle of the hanging beam 102. The U-shaped buckles 103 bear the downward tensile force of the load, and the bolt connection points on both sides of the hanging beam 102 and in the middle generate an upward tensile force. The above design ensures that the stress of each U-shaped buckle 103 is similar and that all bolt connection points are subjected to the same force, thereby reducing the risk factors of stress concentration and bolt failure.

[0031] In this embodiment, reference Figure 2 and 3Both the hanging beam 102 and the span beam 101 adopt a hollow and reinforced structure, which improves the structural strength and significantly reduces the weight of the structure with the same amount of material. The hanging plate 202 adopts a cross-shaped hollow structure, and six sets of hooks 201 are evenly distributed on both sides of the cross-shaped hanging plate, resulting in uniform stress. The hollow design increases the height direction, reduces the structural weight and improves the structural strength.

[0032] In this embodiment, reference Figure 4 The reset button 306 and the PCB module 302 are connected by electronic wires. The external connection wires are soldered to the PCB module 302 through the silicone sealing ring 308, so that the circuit can be sealed with glue after the circuit is soldered and connected, and the whole circuit can be waterproof.

[0033] In this embodiment, reference Figure 4 The PCB potting protective cover 301 has a groove at its inner bottom. The height of the groove is higher than that of the PCB module 302. The PCB module 302 is installed inside the groove by a nut, and the PCB module 302 is installed and fixed by the groove.

[0034] In this embodiment, reference Figure 4 The control line of the servo motor 304 is soldered to the PCB module 302 through the reserved hole. The PCB potting protective cover 301 is located on the outside of the sheet metal connector 303 and the servo motor 304. The servo motor protective cover 305 is fixedly installed on the outside of the sheet metal connector 303. The bottom of one side of the servo motor protective cover 305 has a reserved hole for the bottom of the sheet metal connector 303 to pass through. The PCB module 302 is protected by the PCB potting protective cover 301, and the servo motor protective cover 305 protects the servo motor 304.

[0035] In this embodiment, reference Figure 4 Both the PCB potting protective cover 301 and the servo motor protective cover 305 are made of aluminum alloy. The PCB potting protective cover 301, the servo motor protective cover 305 and the mounting plate 202 are combined to form a sealed space, which isolates the contact between electronic circuits and effectively avoids displacement jitter caused by common servo motor signal interference.

[0036] Working principle: When in use, the two ends of the span beam 101 are assembled to the carbon fiber load-bearing frame of the UAV body by load-bearing bolts. After the throwing component 3 and the mounting plate component 2 are bolted together, they can be quickly inserted and removed by using the hook 201 on the mounting plate component 2 and the U-shaped buckle 103 on the grid beam structure component 1. The load is locked by the cam locking part 203 and the L-shaped locking pin 204, so as to realize the rapid loading and unloading of the load.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
