[0034] In the present application, the unmanned device is exemplified by an unmanned aerial vehicle, which can be used for pesticide spraying or water spraying for crops in the agricultural industry. Of course, the unmanned aerial vehicle can also be used for seed planting, spraying of fire extinguishing liquid in forest fires, aerial photography, power inspection, environmental monitoring, forest fire prevention and disaster inspection in other fields.

[0035] Specifically, please refer to Figures 1-6 The locking assembly 34 in the present embodiment is used to connect the first component and the second component, and includes a first locking piece 341 and a second locking piece. The first locking piece 341 is fixedly connected with the first component, and the second locking piece is fixedly connected with the second component. The first locking piece 341 is provided with a first clamping portion 3411. The second locking piece is provided with a second clamping portion 3441. When the first component and the second component are connected, the first clamping portion 3411 and the second clamping portion 3441 are clamped and buckled to prevent the first component and the second component from being separated.

[0036] Specifically, the second locking piece includes:

[0037] The locking piece body 342 is used to fixedly connect the second component;

[0038] The first pivot piece 343 is pivoted to the locking piece body 342. The first pivot piece 343 rotates relative to the locking piece body 342 to have a locking state and an unlocking state. In the locking state, the first pivot piece 343 is attached to the locking piece body 342. In the unlocking state, the first pivot piece 343 is separated from the locking piece body 342;

[0039] The second pivot piece 344 is pivoted to the first pivot piece 343 and has a second clamping portion 3441 matched with the first clamping portion 3411;

[0040] The locking piece 345 is pivoted with the first pivot 343, and a clamping assembly is arranged on the locking piece body 342 corresponding to the locking piece 345. When the clamping assembly is clamped, the first pivot 343 and the locking piece body 342 are limited in the locking state. When the clamping assembly is unclamped, the first pivot 343 can move relative to the locking piece body 342 to switch to the unlocking state.

[0041] In the scheme, the first component and the second component are buckled through cooperation of the first clamping part 3411 and the second clamping part 3441. The relative position of the first pivot 343 and the locking piece body 342 is limited by arranging the clamping assembly, so that the first pivot 343 cannot move relative to the locking piece body 342 and is kept in the locking state. Thus, the first component and the second component are quickly assembled and the connection stability of the two components is ensured, and the installation reliability is high.

[0042] Specifically, the clamping assembly includes a first hook and a second hook. The first hook is located on the locking piece 345, and the second hook is located on the locking piece body 342. In the locking state, the first hook and the second hook are buckled to limit the rotation of the first pivot 343 relative to the locking piece body 342.

[0043] The locking assembly 34 also includes an elastic reset member arranged to apply a force to the locking piece 345 to move it in the direction of buckling the first hook and the second hook.

[0044] Preferably, the elastic reset member is a torsion spring, the locking piece 345 is pivoted with the first pivot 343 through a first rotating shaft, and the torsion spring is sleeved on the first rotating shaft.

[0045] The torsion spring is arranged to always apply a force to the locking piece 345 to rotate in the direction of cooperating with the second hook. That is, when the locking piece and the locking piece body 342 are located at the position where the first hook and the second hook cooperate, the locking piece 345 automatically rotates in the direction of cooperating with the second hook under the elastic force of the torsion spring, thereby realizing automatic locking.

[0046] Specifically, the locking piece 345 also includes an operation part for operating the rotation of the locking piece 345 around the first rotating shaft, and the operation part and the first hook are in an integral structure. The operation part is used to operate the locking piece 345 to rotate to unclamp the first hook and the second hook.

[0047] It should be noted that the torsion spring is not a limitation of the present solution, and in other embodiments, the torsion spring can not be provided, and only the operation part is provided to operate the locking member 345, that is, the operation part can control the locking member 345 to rotate, so as to realize the cooperation of the first hook and the second hook, or realize the separation of the first hook and the second hook.

[0048] The first pivot 343 is pivoted to the lock holder body 342 through a second pivot shaft, the second pivot 344 is pivoted to the first pivot 343 through a third pivot shaft, the second pivot shaft and the third pivot shaft are arranged in parallel with each other, and the second pivot shaft is arranged close to the first lock holder 341 relative to the third pivot shaft.

[0049] The first pivot 343 is provided with a first shaft seat protruding therefrom, and the locking member 345 is pivoted to the first pivot 343 through the first shaft seat and the first pivot shaft penetrating the shaft seat.

[0050] The first shaft seat includes two first seat bodies arranged at intervals, and the locking member 345 is pivoted between the two first seat bodies.

[0051] The first pivot 343 is provided with a avoiding groove, and the second hook can extend to one side surface of the first pivot 343 provided with the locking member 345 through the avoiding groove.

[0052] Meanwhile, the present embodiment also provides a load connecting structure, which comprises a fixing frame and a load, and the load is detachably mounted on the fixing frame through the above-mentioned lock assembly 34.

[0053] Specifically, the lock assembly 34 is two or more, and is symmetrically arranged on the peripheral part of the load. When the lock assembly 34 is even, it is divided into two groups and is symmetrically arranged relative to the axis of the center of gravity of the load. When the load is odd, one lock assembly 34 is arranged on the axis of the center of gravity of the load, and is symmetrically arranged relative to the axis. The remaining lock assemblies 34 are divided into two groups and are symmetrically arranged relative to the axis of the center of gravity of the load.

[0054] In the description herein, it should be understood that the terms "upper", "lower", "left", "right", and the like orientation or position relationship are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first" and "second" are only used to distinguish in the description, and do not have special meanings.
