TECHNICAL FIELD

[0001] The present application belongs to the technical field of unmanned aerial vehicles, in particular relates to a kind of semi-automatic unmanned aerial vehicle carrying platform. BACKGROUND

[0002] The current unmanned aerial vehicle air drop hoisting material and equipment are mostly hoisted by flexible sling and unlocked by automatic device such as rudder. Flexible sling can only hoist light weight material and equipment. When hoisting heavy material and equipment by flexible sling, the unmanned aerial vehicle will be affected by the inertia of material and equipment during acceleration and turning, and will fall out of balance.

[0003] Therefore, how to reduce the imbalance of unmanned aerial vehicle during state change has become a problem to be solved. SUMMARY

[0004] The present application aims to solve the problems raised in the background art and proposes a kind of semi-automatic unmanned aerial vehicle carrying platform.

[0005] In order to achieve the purpose of the present application, the present application provides a kind of semi-automatic unmanned aerial vehicle carrying platform.

[0006] When the unmanned aerial vehicle carrying platform is mounted with hoisted material and equipment, the handle of the self-locking mechanism is manually pulled to separate the locking tongue from the locking hole of the fixed plate, and the hoisting mechanism is unlocked. Under the action of gravity, the hoisting plate falls and the distance to the unlocking crossbar is reduced. The rotation center of the hoisting hook is fixed on the hinge seat, and the other end is fixed on the connecting rod, both of which are fixed by hinge pins. The other end of the connecting rod is fixed on the locking crossbar, and the hinge seat is fixed on the hoisting plate. The unlocking crossbar, linear bearing, hoisting rod, fixed plate, hoisting plate, connecting rod, hoisting hook, hinge seat, hinge pin form a crank slider mechanism. After the distance between the hoisting plate and the unlocking crossbar is reduced, the hoisting hook also falls. The hook on the hoisting hook falls into the corresponding hoisting hole of the hoisted material and equipment. When the unmanned aerial vehicle takes off, the hook contacts the hoisting hole, and the side hook on the hook ensures that the hook will not come out of the hoisting hole. When multiple pairs of hoisting hooks are configured, they are fixed on the same unmanned aerial vehicle plane by the fixed plate, and the hoisting hooks are fixed on the same hoisting plate to realize the synchronous action of the hoisting hooks. The reinforcing plate ensures the stability and stiffness of the rotating hook mechanism.

[0007] When the unmanned aerial vehicle carrying platform is unlocked, the unmanned aerial vehicle lands, the hoisted material falls to the ground, the lifting hook on the lifting hook is separated from the lifting hole corresponding to the hoisted material and equipment, the unlocking plate of the unlocking support contacts the hoisted material or equipment and lifts the lifting plate, the distance between the lifting plate and the unlocking horizontal rod is increased, and the lifting hook is driven to open. The buffer spring, spring support, spring guide rod, unlocking linear bearing and guide rod card of the unlocking support constitute a buffer mechanism, that is, the unlocking support plays a buffering role in the unlocking process, avoiding damage to the hoisted goods caused by the impact when the unmanned aerial vehicle lands and the pressure of the weight of the unmanned aerial vehicle.

[0008] When the lifting hook is fully opened, the locking tongue of the self-locking mechanism enters the locking hole of the fixed plate, the self-locking of the lifting mechanism is completed, the detection plate triggers the detection photoelectricity, and a locking-in-place signal is given, indicating that the carrying platform completes unlocking and the unmanned aerial vehicle flies away to complete the hoisting carrying task.

[0009] Compared with the prior art, the significant progress of the present application is that the present application provides a semi-automatic mechanical unlocking unmanned aerial vehicle carrying platform, which has simple system structure and high reliability in launching and unlocking.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] The unmanned aerial vehicle carrying platform comprises a lifting mechanism 10, a self-locking mechanism 20, an unlocking support 30 and a detection device 40. The lifting mechanism 10 is a main body structure and a symmetrical structure, and the self-locking mechanism 20 is arranged on the lifting mechanism 10. The unlocking support 30 is arranged on the bottom surface of a linear bearing 15 of the lifting mechanism 10, and the detection device 40 is arranged on a fixed plate 11 of the lifting mechanism.

[0022] The lifting mechanism 10 comprises the fixed plate 11, a lifting plate 12, a hinge seat 13, a lifting hook 14, the linear bearing 15, a lifting rod 16, a connecting rod 17, a hinge pin 18, an unlocking crossbar 19 and a reinforcing plate 110. The lifting mechanism 10 is used for lifting materials and equipment by the unmanned aerial vehicle. The two ends of the unlocking crossbar 19 are connected to the connecting rod 17. The connecting rod 17 is connected to the lifting hook 14. The lifting hook 14 can be switched between vertical and horizontal states as needed.

[0023] The unmanned aerial vehicle carrying platform is fixed to the unmanned aerial vehicle by two fixed plates 11. The fixed plate 11 and the vertically arranged lifting rod 16 are fixed together with the horizontally arranged unlocking crossbar 19. The distance between the fixed plate 11 and the unlocking crossbar 19 is constant. The lifting plate 12 is arranged on the lower layer of the fixed plate 11. The linear bearing 15 is fixed on the lifting plate 12 and passes through the lifting rod 16, so that the lifting plate 12 can move between the fixed plate 11 and the unlocking crossbar 19.

[0024] The self-locking mechanism 20 comprises a lock body 21, a lock tongue 22, an elastic element 23 and a handle 24, and is used for locking after the unlocking of the lifting mechanism. The lock tongue 22 and the elastic element 23 are arranged inside the lock body 21. One end of the lock body 21 is provided with the handle 24, and the other end is provided with the lock tongue 22.

[0025] The self-locking mechanism 20 is fixed on the lifting plate 12. During the unlocking process, the distance between the lifting plate 12 and the fixed plate 11 decreases, and the lifting plate 12 abuts against the curved surface of the lock tongue 22. The lock tongue 22 is retracted and automatically ejected under the action of the elastic element 23 and the lock body 21. The lock tongue 22 is inserted into the lock hole of the fixed plate 11, so that the lifting plate 12 cannot fall.

[0026] The unlocking support 30 is sequentially provided with an unlocking plate 31, a buffer spring 32, a spring support 33, a spring guide rod 34, an unlocking linear bearing 35 and a guide rod card 36 from bottom to top; the buffer spring 32 is in a pre-compressed state to provide an initial unlocking support force; the unlocking support 30 is fixed on the hoisting mechanism 10 and is used for unlocking action of the hoisting mechanism.

[0027] The unlocking support 30 of the unmanned aerial vehicle carrying platform is in contact with the hoisted materials and equipment, and then lifts the hoisting plate 12, increases the distance between the hoisting plate 12 and the unlocking cross rod 19, drives the hoisting hook 14 to open, and unlocks the hoisting mechanism 10.

[0028] The unlocking cross rod 19, the linear bearing 15, the hoisting rod 16, the fixed plate 11, the hoisting plate 12, the connecting rod 17, the hoisting hook 14, the hinge seat 13 and the hinge pin 18 constitute a crank slider mechanism, as shown in the figure. Figure 9 The linear bearing 15, the hoisting plate 12 and the hinge seat 13 are fixed together to constitute a rack part of the crank slider mechanism, the hoisting hook 14 constitutes a crank, the connecting rod 17 is a connecting rod, and the unlocking cross rod 19, the hoisting rod 16 and the fixed plate 11 are fixed together to constitute a slider part, the movement of the slider drives the crank to rotate, and then the hoisting hook 14 opens or falls with the change of the distance between the hoisting plate 12 and the unlocking cross rod 19.

[0029] The buffer spring 32, the spring support 33, the spring guide rod 34, the unlocking linear bearing 35 and the guide rod card 36 of the unlocking support 30 constitute a buffer mechanism, and in the unlocking process, the unlocking plate 31 of the unlocking support 30 is in contact with the hoisted materials and equipment, and then the force transmission route from the unlocking plate 31 to the buffer spring 32 to the spring support 33 to the hoisting plate 12 is formed; the hoisting plate 12 is lifted and drives the self-locking mechanism 20 arranged on the hoisting plate 12 to approach the fixed plate 11, the locking tongue 22 is inserted into the lock hole of the fixed plate 11, the hoisting plate 12 cannot fall, the unlocking process is completed, and then when the unmanned aerial vehicle continues to descend, the buffer spring 32 is compressed under the action of external force and plays a buffering role, so as to avoid damage to the hoisted goods caused by the impact when the unmanned aerial vehicle lands and the pressure of the weight of the unmanned aerial vehicle.

[0030] The unlocking support 30 of the unmanned aerial vehicle carrying platform is in contact with the hoisted materials and equipment, and then lifts the hoisting plate 12, and the locking tongue 22 of the self-locking mechanism 20 is inserted into the lock hole of the fixed plate 11 to make the hoisting plate 12 unable to fall.

[0031] The detection device 40 includes a detection photoelectric cover 41, a detection photoelectric 42 and a detection plate 43, and is used for unlocking position detection of the hoisting mechanism.

[0032] The unmanned aerial vehicle (UAV) transport platform is equipped with a detection device 40. After the unlocking bracket 30 comes into contact with the hoisted material and equipment, it lifts the hoisting plate 12. After the locking tongue 22 of the self-locking mechanism 20 is inserted into the lock hole of the fixed plate 11, the detection plate 43 triggers the detection photoelectric sensor 42 to give an unlocking signal.

[0033] The aforementioned drone carrier platform, with its reinforcing plate 110, ensures the stability and rigidity of the rotating hook mechanism.

[0034] like Figure 6 As shown, the self-locking mechanism of the UAV transport platform is manually unlocked. After unlocking, the lifting mechanism lowers the lifting plate under its own weight, reducing the distance between the lifting plate and the unlocking crossbar, thus causing the opened lifting hook to fall. After falling, the hook on the hook passes into the corresponding lifting hole of the lifted material and equipment, as shown. Figure 7 As shown. When the drone takes off, the hook contacts the lifting hole. The side hook on the hook ensures that it will not come out of the lifting hole, ensuring the reliability of the lifting process. Figure 8 As shown. When multiple pairs of rotating hook mechanisms are configured, they are fixed to the same UAV plane by a fixing plate, and the rotating hook mechanisms are fixed to the same lifting plate, which can realize the synchronous movement of the lifting hooks. The reinforcing plate can ensure the stability and rigidity of the rotating hook mechanism.

[0035] When the UAV carrier platform is unlocked, the UAV lands, the hoisted goods fall to the ground, and the hook on the swivel disengages from the hoisting hole corresponding to the hoisted goods and equipment. Figure 7 As shown. The unlocking plate of the unlocking bracket contacts the suspended material and equipment, lifting the lifting plate and increasing the distance between the lifting plate and the unlocking crossbar, causing the lifting hook to open, as shown. Figure 5 As shown. The buffer spring, spring bracket, spring guide rod, unlocking linear bearing, and guide rod clip of the unlocking bracket constitute a buffer mechanism, which plays a buffering role during the unlocking process, avoiding damage to the hoisted goods caused by the impact of the drone landing and the pressure of the drone's own weight. When the hoisting hook is fully open, the locking tongue of the self-locking mechanism enters the lock hole of the fixed plate, completing the self-locking of the hoisting mechanism. At the same time, the detection plate triggers the detection photoelectric sensor, giving an unlocking completion signal, indicating that the transport platform has completed unlocking and the drone can fly away to complete the hoisting and transporting task.
