Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to an anti-collision buffer mechanism for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, or UAVs for short, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by onboard computers. Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian sector, drones + industry applications are the real rigid demand for drones; they are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, and so on.

[0003] The propeller blades of existing drones are generally wrapped by corresponding mesh covers to protect the propeller blades, so as to prevent the drone from falling and hitting the ground when it loses control, thereby causing damage to the propeller and the drone body. However, such anti-collision devices will affect the flight performance of the drone, reduce the lift of the drone, and greatly increase the flight resistance of the drone, making it inconvenient for the drone to fly. At the same time, the cushioning and anti-collision performance of the drone body is poor, and the drone cannot be well protected when it crashes. Utility Model Content

[0008] The working principle and advantages of the utility model are as follows: the anti-collision buffer mechanism of the UAV connects and fixes the connection components into a whole through a connection frame, and then installs buffer components on the upper and lower sides of the connection frame. The two buffer components are locked and fixed via the connection components.

[0015] The following is a further detailed description through specific implementation methods:

[0016] like Figures 1 to 4 As shown:

[0017] A collision avoidance and buffering mechanism for a UAV comprises a connecting frame 4, a plurality of connecting components and two groups of buffer components. Each of the connecting components is evenly installed on the side of a UAV body 1. Each of the connecting components is fixedly connected through the connecting frame 4, that is, the connecting frame 4 is installed on the outside of the UAV body 1 through a plurality of connecting components to surround the UAV body 1. Two groups of buffer components are symmetrically installed on both sides of the connecting frame 4. The buffer components are adapted to the connecting frame 4. The buffer components are used to store energy and slowly release the impact force on the UAV when the UAV body 1 falls, so as to achieve the collision avoidance and buffering effect.

[0018] The buffer assembly includes a buffer frame 10, a plurality of buffer springs 12 and a plurality of storage sleeves 13. The buffer frame 10 is adapted to the connecting frame 4. A plurality of storage sleeves 13 for storing the buffer springs 12 are evenly arranged on the buffer frame 10. One end of the buffer spring 12 is installed in the storage sleeve 13, and the other end of the buffer spring 12 is fixedly installed on the connecting frame 4. A connecting ear 11 is provided at one end of the buffer frame 10 close to the connecting frame 4. The two buffer frames 10 are locked and fixed with the connecting assembly through the connecting ear 11, so that the two buffer frames 10 are fitted on the connecting frame 4, and the buffer spring 12 is compressed in the storage sleeve 13.

[0019] The connecting assembly includes a connecting module and a fixing module. The connecting module is used for connecting the connecting frame 4 and the drone body 1, and the fixing module is used to lock the two buffer frames 10 at the connecting frame 4, so that the connecting frame 4 and the buffer frame 10 form a whole, reducing their air resistance. At the same time, the connecting frame 4 and the buffer frame 10 are no longer on the upper and lower sides of the propeller of the drone body 1, effectively reducing the influence of this mechanism on the aerodynamic performance of the propeller; the connecting module is mainly a connecting spring 2 and a connecting seat 3. The connecting seat 3 is connected to the drone body 1 through the connecting spring 2. The connecting spring 2 can store energy and slowly release it. At the same time, it can consume part of the kinetic energy when it is deformed. The connecting seat 3 is used to connect with the connecting frame 4 and to install the fixing module. The connecting seat 3 is provided with a mounting hole 5 and a slot 6 for installing the fixing module.

[0020] The fixing module includes an electromagnet 7, a push spring 8 and an iron pin 9. The electromagnet 7 is fixedly installed at the bottom of the mounting hole 5, and the iron pin 9 is slidably installed in the mounting hole 5. The iron pin 9 and the electromagnet 7 are connected by the push spring 8, so that the electromagnet 7 can adsorb the iron pin 9, the push spring 8 can push the iron pin 9, the connecting ear 11 at the buffer frame 10 can be inserted into the slot 6, and the iron pin 9 can be inserted into the connecting ear 11, so that the iron pin 9 can lock the connecting seat 3 and the two buffer frames 10 together.

[0021] The specific implementation process is as follows:

[0022] The anti-collision buffer mechanism of the drone can be installed on the drone body 1 to buffer the drone body 1; during the flight of the drone body 1, the two buffer frames 10 are buckled on the connecting frame 4 through a fixing mechanism. If the drone body 1 crashes or other unexpected situations occur, the anti-collision buffer mechanism of the drone can be started by remote control or a built-in program of the drone body 1; when the anti-collision buffer mechanism is started, the electromagnet 7 works, the electromagnet 7 attracts the iron pin 9, the push spring 8 is compressed, the iron pin 9 is pulled out from the connecting ears 11 at the two buffer frames 10, the two connecting ears 11 are released, the two buffer frames 10 are released, and are bounced open under the elastic force of the buffer spring 12, and separated from the connecting frame 4, so that the buffer The frame 10 and the storage sleeve 13 are located outside the propeller of the drone body 1 and outside the bottom of the drone body 1, so that the outer frame formed by the two buffer frames 10, each storage sleeve 13 and each buffer spring 12 completely wraps the drone body 1. When the drone body 1 falls to the ground, the outer frame formed by the two buffer frames 10, each storage sleeve 13 and each buffer spring 12 contacts the ground to prevent the drone body 1 from directly contacting the ground. At the same time, each buffer spring 12 and each connecting spring 2 stores energy for the impact force between the drone body 1 and the ground and releases the corresponding kinetic energy, thereby realizing the anti-collision and buffering functions of the drone body 1.

[0023] When installing the buffer frame 10 back to the connecting frame 4, the buffer frame 10 is squeezed toward the connecting frame 4 so that the buffer spring 12 is compressed and returned to the storage sleeve, and the connecting ear 11 of the buffer frame 10 is inserted into the slot 6 at the connecting seat 3. Then the electromagnet 7 is controlled to release the iron pin 9. Under the action of the push spring 8, the iron pin 9 is inserted into the connecting ear 11, so that the connecting seat 3, the connecting frame 4 and the two buffer frames 10 can be fixed together.

[0024] The anti-collision buffer mechanism of the UAV connects and fixes the connection components into a whole through the connection frame 4, and then installs buffer components on the upper and lower sides of the connection frame 4. The two buffer components are locked and fixed via the connection components. When the UAV body 1 falls out of control, each connection component releases the two buffer components, so that the two buffer components completely surround the UAV body 1, store energy and slowly release the impact when the UAV body 1 crashes, effectively reducing the probability of damage to the UAV when it hits the ground. At the same time, the mechanism can effectively reduce its impact on the UAV body 1 during flight, ensuring the normal operation of the UAV body 1.

It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, which will not affect the effect of the implementation of the utility model and the applicability of the patent.
