[0002] The operation of using unmanned aerial vehicles to transport materials is becoming more and more common, and the load capacity of unmanned aerial vehicles shows a gradually increasing trend, and the load capacity can even reach dozens of kilograms. Generally speaking, between the cargo hold of express logistics and the fuselage of the unmanned aerial vehicle, a manual structure is often used for manual locking and unlocking, making it difficult to achieve automatic loading and unloading of goods; in the prior art, there has also appeared a method of using a servo motor as an actuator for locking and unlocking. Although automatic loading and unloading can be achieved, in this case, the load of the cargo hold is completely borne by the servo motor, and the torque of the servo motor overcomes the load, resulting in limited load capacity and low safety and reliability. Therefore, how to solve the problems of limited load capacity and low safety and reliability in the prior art for the loading and unloading methods of unmanned aerial vehicles under the requirement of automation has become an important technical problem to be solved by those skilled in the art.

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] As Figures 1-4 shown, the embodiment of the present application provides a loading and unloading lock that can be detachably connected to the lock catch 102, including a seat body 1, a linkage assembly, and a first driver 2; the linkage assembly is movably connected to the seat body 1 and can act, and is provided with a connection part 42 that can be connected to the lock catch 102. The action state of the linkage assembly includes a locked state in which the connection part 42 is connected to the lock catch 102 and a self-locking relationship is formed between the components of the linkage assembly, and an unlocking state in which the lock catch 102 can be disengaged; when the linkage assembly is in the locked state, it has no degree of freedom of movement in the load direction and only has a degree of freedom of movement in the driving direction of the first driver 2; the first driver 2 is provided on the seat body 1 and can drive the linkage assembly from the locked state to the unlocking state.

[0048] With such arrangement, the cargo hold is locked with the loading and unloading lock through the lock buckle 102. When loading operations are performed, the lock buckle 102 is connected to the linkage assembly, and the linkage assembly is affected by the force brought by the lock buckle 102, and the whole body can move and achieve self-locking, and the current state is the locked state, and the locked state is maintained so that the lock buckle 102 cannot be disengaged. In this way, physical self-locking is achieved through pure structural coordination, so that the actual load-bearing is the non-electrical component, and due to the self-locking characteristics, when the load brought by the lock buckle 102 is high, the self-locking force of the linkage assembly becomes stronger accordingly. Compared with the method of using electric control mechanisms such as servos to carry loads, the technical solution provided in the present application has an improved load-bearing capacity and improved safety and reliability. When unloading operations are required, the first drive 2 can be operated to meet the needs of automation, and solves the problem that the load-bearing capacity is limited and the safety and reliability are low while meeting the requirements of automation in the prior art for loading and unloading drones.

[0049] It should be noted that the base body 1 is a structure with a chamber, and specifically can be composed of a front cover, a middle frame and a rear cover. The base body 1 is provided with a lock slot 101 extending inward from the edge and for the lock buckle 102 to extend into. The lock slot 101 is in a notch shape. When the linkage assembly is in a locked state, the connecting portion 42 is at least partially located in the lock slot 101.

[0050] In a preferred embodiment, the loading and unloading lock also includes a safety mechanism that is arranged on the base body 1 and is capable of operation. When the linkage assembly switches from a locked state to an unlocked state, it passes through an unlocking path. The action state of the safety mechanism at least includes a limit state in which the blocking limit is on the unlocking path, and a release state away from the unlocking path.

[0051] With such arrangement, on the one hand, when the linkage assembly is in a locked state, the safety mechanism is used to strengthen the locking, which also has a safety effect for preventing the first drive 2 from starting accidentally, or the linkage assembly from being unlocked due to a bump in the drone; on the other hand, the load-bearing capacity of the linkage assembly can be further improved without the need to increase the load-bearing capacity by using a servo with a large output torque, thus avoiding the disadvantages of heavy weight and large volume brought by a servo with a large torque, and ensuring that the loading and unloading lock always has the advantages of small volume and light weight.

[0052] Through the actual test of the loading and unloading lock being put into use, when the loading and unloading lock weighs 100g, its maximum load capacity reaches or even exceeds 100kg, which has a considerable advantage in terms of light weight and large load.

[0053] It should be noted that, in the loading and unloading lock provided in the present application, a controller is installed in the base body 1, and the electric control structures mentioned in this article are all communicatively connected with the controller.

[0054] In a specific embodiment, the loading and unloading lock further includes a first sensor disposed in the seat body 1. The position where the first sensor is fixed enables it to sense the unlocking mechanism in the unlocked state, and it is communicatively connected to the first driver 2.

[0055] With such a setting, after the first sensor senses the unlocking mechanism, it ensures that the unlocking mechanism is in an unlocked state that will not affect the operation of the linkage assembly, and then sends a signal to the controller. The controller controls the operation of the first driver 2, so that the first driver 2 drives the linkage assembly to move from the locked state to the unlocked state. The first sensor real-time feedbacks the position state, which is beneficial to the safe, reliable and smooth operation of the entire action process of the loading and unloading lock.

[0056] In another preferred embodiment, the loading and unloading lock further includes a second sensor disposed in the seat body 1. The position where the second sensor is fixed enables it to sense the linkage assembly in the locked state, and it is communicatively connected to the unlocking mechanism.

[0057] With such a setting, after the second sensor senses the linkage assembly, it ensures that the linkage assembly is in a locked state where it has been connected to the lock catch 102 and self-locked, and then sends a signal to the controller. The controller controls the operation of the unlocking mechanism, so that the unlocking mechanism moves from the unlocked state to the limited state. The second sensor real-time feedbacks the position state, which is beneficial to the safe, reliable and smooth operation of the entire action process of the loading and unloading lock.

[0058] In a preferred embodiment, the loading and unloading lock further includes a manual unlocking body 3 connected to the linkage assembly. A part of the manual unlocking body 3 protrudes from the seat body 1, and moving along the unlocking direction can drive the linkage assembly to move to the unlocked state. Specifically, the manual unlocking body 3 can be a pull ring or a handle.

[0059] With such a setting, when the loading and unloading lock is not powered on or fails and cannot be automatically released and unlocked, when the drone returns to the ground, the manual unlocking body 3 can be pulled along the unlocking direction to manually unlock and release.

[0060] Regarding the composition of the linkage assembly, through the special shape design of each component, it is realized that the components can cooperate with each other to achieve self-locking. In the following text and the accompanying drawings, the first clockwise direction refers to the clockwise direction, and the second clockwise direction refers to the counterclockwise direction.

[0061] In a specific embodiment, the components of the linkage assembly include a hook 4 and a locking lever 6; the hook 4 is rotatably connected to the base body 1 through a pin shaft, and is provided with a connecting portion 42 capable of being hooked to the locking buckle 102. A part of the hook 4 can be exposed in the locking groove 101 so that the locking buckle 102 can push it; the locking lever 6 is rotatably connected to the base body 1 through a pin shaft, and has a rotational torque in the first clockwise direction, that is, has a tendency to rotate in the first clockwise direction; wherein, when the linkage assembly is in the unlocked state, the hook 4 is in the position to be hooked, the opening of the hook 4 generally faces the approaching locking buckle 102, and the hook 4 can be pushed by the locking buckle 102 to rotate in the second clockwise direction and be hooked to the locking buckle 102, and a self-locking relationship that restricts the rotation of each other is formed between the hook 4 and the locking lever 6 to switch to the locked state; at this time, the locking lever 6 only has a rotational freedom in the second clockwise direction; when the linkage assembly is in the locked state, the locking lever 6 can be driven by the first driver 2 to rotate in the second clockwise direction to switch to the unlocked state. The manual unlocking body 3 is also connected to the locking lever 6.

[0062] With such a setting, the hooking of the locking buckle 102 is realized through the hook portion of the hook 4 as the connecting portion 42, and the locking buckle 102 is generally an annular fastener, that is, the load-bearing assembly form of the hook 4 is adapted to that of the locking buckle 102; the locking lever 6 is the actuator for unlocking, and the rod-shaped structure can provide a suitable force arm, which is beneficial to reducing the output torque that the first driver 2 needs to meet, that is, the first driver 2 can be set as a small-sized or low-power mechanism.

[0063] Furthermore, the linkage assembly further includes a buckle 5. The buckle 5 is rotatably connected to the base body 1 through a pin shaft and has a rotational torque in the second clockwise direction; wherein, the hook 4 is provided with a first limiting convex portion 41; the buckle 5 is provided with a first limiting concave portion 51 capable of being in limiting cooperation with the first limiting convex portion 41, and a second limiting convex portion 52; the locking lever 6 is provided with a second limiting concave portion 61 capable of being in limiting cooperation with the second limiting convex portion 52; when the hook 4 is in the position to be hooked, the first limiting convex portion 41 is disengaged from the first limiting concave portion 51, and the second limiting convex portion 52 is disengaged from the second limiting concave portion 61. Under the action of the rotational torque, the locking lever 6 presses on the buckle 5, and the buckle 5 presses on the hook 4, and the linkage assembly is in the unlocked state; when the hook 4 is pushed by the locking buckle 102 and rotates in the second clockwise direction, it pushes the buckle 5 to rotate in the first clockwise direction, the first limiting convex portion 41 slides into the first limiting concave portion 51, and the second limiting convex portion 52 slides into the second limiting concave portion 61 to make the linkage assembly in the locked state.

[0064] In this way, through the driving torque, the limiting concave part and the limiting convex part are closely matched, and they block each other at the forward position of the rotation tendency of the other, forming a lever structure with reliable self-locking. It should be noted that, in order to make the first limiting convex part 41 slide into the first limiting concave part 51 and the second limiting convex part 52 slide into the second limiting concave part 61 smoothly, as shown in the figure, a mating inclined plane is provided between the two mating parts.

[0065] Furthermore, in order to ensure the stable rotation trajectories of the hook 4, the buckle 5 and the locking rod 6 and strengthen the actual restoration degree of the self-locking position design, it is preferred that the seat body 1 is provided with a sliding groove, and each component is provided with a protrusion that slides in the sliding groove to limit the sliding trajectories of the respective components.

[0066] In addition, the realization of the driving torque of the buckle 5 and the locking rod 6 can specifically be that torsion springs are provided between the buckle 5 and the seat body 1 and between the locking rod 6 and the seat body 1, and the torsion springs are sleeved on the pin shafts, or it can also be other forms of springs or elastic structures; regarding the realization of the hook 4 being held in the position to be hung, specifically, a third magnet 9 that adsorbs the hook 4 in the position to be hung is provided at the designed position in the seat body 1. Specifically, the first limiting convex part 41 and / or the connecting part 42 of the hook 4 are subjected to the suction force of the third magnet 9. It is preferred that the third magnet 9 is provided at the position in the seat body 1 corresponding to the first limiting convex part 41 and the position in the seat body 1 corresponding to the connecting part 42, and the pushing of the lock catch 102 can resist the suction force of the magnet.

[0067] In an alternative embodiment, the hook 4 is provided with a second magnet 8, and the seat body 1 is provided with a second magnetic induction sensor. When the hook 4 is in the position to be hung, the second magnetic induction sensor can sense the second magnet 8. After the hook 4 leaves the position to be hung, the linkage assembly is in the locked state, and the second magnetic induction sensor loses the induction of the second magnet 8 and generates a corresponding signal. This is used as the specific implementation method of the second sensor in the above text. Of course, it is also feasible for the second sensor to adopt a conventional induction device such as an optoelectronic switch.

[0068] In a specific embodiment, the safety mechanism includes a rotating body and a second driver 11; the rotating body is provided with an eccentric part 10 protruding radially; the second driver 11 drives the rotating body to rotate; wherein, when the eccentric part 10 is located on the unlocking path and abuts against the locking rod 6 of the linkage assembly, the safety mechanism is in the limiting state; when the eccentric part 10 is away from the unlocking path and releases the abutment against the locking rod 6 of the linkage assembly, the safety mechanism is in the unlocking state. With such a setting, the rotating body is the executor of the action, with a small action range, saving space, being beneficial to the compact layout of the structure in the loading and unloading lock, and achieving a small volume.

[0069] Moreover, in addition to the above-mentioned rotating form, it is also feasible to set the second driver 11 to drive a movable part that can translate.

[0070] In an alternative embodiment, a first magnet 7 is provided on the eccentric part 10, and a first magnetic induction sensor is provided in the base body 1. When the eccentric part 10 abuts against the linkage assembly, the first magnetic induction sensor can sense the first magnet 7 and generate a corresponding signal. This is taken as a specific implementation manner of the first sensor in the above text. Of course, it is also feasible for the first sensor to adopt a conventional induction device such as a photoelectric switch.

[0071] In an alternative embodiment, the second driver 11 is a servo motor or a torque motor. In this way, when setting up the electronic control mechanism, compared with the way of using a servo motor and other electronic control mechanisms to fully load in the prior art, the servo motor and other electronic control mechanisms in the present application only need to output a small torque to achieve auxiliary limit.

[0072] In an alternative embodiment, the first driver 2 is an electromagnetic push rod or an electric push rod. It is preferably set as an electromagnetic push rod, and the trigger is not interfered by external electromagnetic signals, which is more stable and reliable.

[0073] After comprehensively implementing the above settings of the magnetic induction sensor cooperating with the magnet, the servo motor, and the electromagnetic push rod, the loading and unloading lock has the advantage of fast trigger response time. Through the physical test of the loading and unloading lock in use, it is found that the single delay is less than 20 ms, and the consistency between clusters is less than 10 ms. It avoids the disadvantages of poor response consistency of the lock mechanism with a servo motor as the actuator in the prior art, high delay and poor consistency when multiple mechanisms are linked, and difficulty in accurately releasing.

[0074] In another preferred embodiment, the loading and unloading lock further includes an indicating structure 12 connected to the safety mechanism. The indicating structure 12 can be a pointer fixedly connected to the rotating body. Locking marks and unlocking marks are provided on the outer wall of the base body 1. At least part of the indicating structure 12 protrudes from the base body 1, and the indicating structure 12 can be switched between pointing to the locking mark and pointing to the unlocking mark under the drive of the safety mechanism. With such a setting, even if the base body 1 is an opaque structure, the user can still know the current internal structural state of the base body 1 through external indication, which is convenient to use.

[0075] Based on the above loading and unloading lock, an embodiment of the present application further provides a drone, which includes a fuselage and a cargo compartment. The above loading and unloading lock is provided on the fuselage, and a lock catch 102 is provided on the cargo compartment. The lock catch 102 is detachably connected to the loading and unloading lock. Since the drone has the above loading and unloading lock, the beneficial effects brought by the loading and unloading lock to the drone can be seen in the above content and will not be elaborated here.
