Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an automatic delivery mechanism for UAVs. Background Art

[0002] With the continuous maturity and popularization of drone technology, the demand for its application in material delivery, signal transmission, etc. is also increasing. Especially in scenarios such as emergency rescue, military reconnaissance, and cargo transportation, drones can quickly reach designated locations and achieve fast and accurate material delivery or information transmission. Therefore, it is particularly important to develop an efficient and reliable drone automatic delivery mechanism.

[0003] The reference announcement number is CN213892913U, which is an automatic delivery mechanism for drones. It is mainly composed of a shell, a hook, a connecting rod, a spring, an outer cover, and a lifting ring. The hook is connected to the shell through an axis 1, and the connecting rod is connected to the hook through a cylindrical pin. This delivery mechanism uses the gravity of the hoisted object to form a closed space between the hook and the shell, thereby lifting the object; after the object touches the ground, the hook loses external force, and the spring force causes the hook to retract, thereby opening the closed space formed by the hook and the shell, and unhooking the object. According to the above, although the delivery mechanism is set to be purely mechanical and has been well applied, the bottom of the object usually needs to contact the ground before the object can be delivered. During this process, the drone needs to stay at a low altitude for operation, and the propeller of the drone is easily damaged by contact with people or objects, thereby affecting the service life of the drone. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatic delivery mechanism for a drone, so as to solve the problem proposed in the above background technology that although the delivery mechanism is set to be purely mechanical and has been well applied, the bottom of the object usually needs to touch the ground before the object can be delivered. During this process, the drone needs to stay at a low altitude for operation, and the propeller of the drone is easily damaged by contact with people or objects, thereby affecting the service life of the drone.

[0005] The lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of the lifting of

[0006] Preferably, a bearing seat is provided at the lower end of the surface of the drone body, and a camera is installed at the bottom end of the bearing seat. The camera is set to monitor the delivery status of the object.

[0007] Preferably, a wireless transmission module is provided at the top of the drone body, and a rack is provided at the corner position of the outer wall of the drone body. A propeller is provided at the end of the rack away from the drone body. The propeller and the rack are arranged so as to cooperate with the drone body to form a drone.

[0008] Preferably, a motor is installed on the outer wall of the first side seat body, one end of the motor passes through the first side seat body and is connected to one end of the retractable roller, so that the retractable roller is driven to rotate through the setting of the motor.

[0009] Preferably, a telescopic driving member is installed on the inner wall of the lower end of the second side connecting seat, and the end of the telescopic driving member away from the second side connecting seat is connected to the outer wall of the movable plate body. The telescopic driving member is arranged to drive the movable plate body to translate.

[0010] Preferably, a hanging plate is provided on the inner wall of the lower end of the movable plate body, and the end of the hanging plate away from the movable plate body touches the inner wall of the fixed plate body. The setting of the hanging plate allows the sling component of the object to be hoisted.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the automatic delivery mechanism for a drone can not only reduce the phenomenon of propellers being damaged by contact with people or objects, thereby extending the service life of the drone, but also achieve the purpose of facilitating automatic delivery of objects and remotely monitoring the delivery status of objects;

[0012] (1) The motor drives the reel to rotate, so that the reel unwinds the rope, thereby moving the suspension component below the load plate downward, and moving the object hoisted by the suspension component downward to the ground. During this process, the drone consisting of the drone body, frame and propeller can stay in a high-altitude area for operation, so as to reduce the phenomenon of the propeller contacting people or objects and being damaged by impact, thereby extending the service life of the drone;

[0013] (2) The movable plate body is driven to move in translation by the telescopic driving member, so that the movable plate body drives the guide cylinder located on the outer wall of the guide rod to slide, so that the movable plate body drives the hanging plate to move horizontally smoothly. When one end of the hanging plate abuts against the inner wall of the fixed plate body, the sling part of the object can be hung on the hanging plate. When one end of the hanging plate no longer abuts against the inner wall of the fixed plate body, the sling of the object will slide off the hanging plate due to the inclined setting of the hanging plate, thereby achieving the purpose of facilitating the automatic placement of the object.

[0014] (3) By setting a camera at the bottom of the supporting base on the surface of the drone body, the camera can take pictures and record the placement status of the object. The captured placement data can be transmitted to an external terminal by a wireless transmission module, thereby achieving the purpose of remotely monitoring the placement status of the object.
