[0032] The present application will be further described below with reference to the accompanying drawings and implementation methods.

[0033] An embodiment of the present application provides a detection device for a drone, see Figure 1 and Figure 2As shown, the detection device 100 for a UAV includes: a load-bearing portion 10 , a fixing portion 20 and a plurality of first sensing portions 30 .

[0034] The load-bearing portion 10 includes an elastic member 11, a load plate 12, and a connector 13. The first end of the elastic member 11 is located at the bottom of the drone, and the load plate 12 is located at the second end of the elastic member 11, that is, the load plate 12 is connected to the end of the elastic member 11 away from the drone. The connector 13 is located at the end of the load plate 12 away from the elastic member 11 and is used to connect the load. In an optional embodiment, the elastic member 11 is connected to the center of the side of the load plate 12 facing the drone, and the connector 13 is connected to the center of the side of the load plate 12 facing away from the drone.

[0035] Among them, there are multiple fixing parts 20, and multiple fixing parts 20 are arranged at the bottom of the drone. Multiple fixing parts 20 are arranged along the circumference of the load plate 12. The fixing part 20 includes a cantilever 21 connected to the bottom of the drone and a protruding arm 22 bent from the end of the cantilever 21 away from the drone toward the load plate 12. The load plate 12 is suspended at the bottom of the drone by an elastic member 11, and the side of the load plate 12 facing away from the drone is in contact with the protruding arm 22. Multiple protruding arms 22 cooperate with each other to support the load plate 12.

[0036] Among them, there are multiple first sensing parts 30, and the multiple first sensing parts 30 are respectively arranged on the multiple fixing parts 20 in a one-to-one correspondence. The first sensing part 30 is arranged on the side of the cantilever 21 facing the load plate 12, and the first sensing part 20 is located at a position opposite to the cantilever 21 and the load plate 12. That is to say, the first sensing part 20 is arranged between the cantilever 21 and the side of the load plate 12. The first sensing part 30 is used to detect the pressure applied by the load plate 12 toward the cantilever 21. When the load is suspended at the bottom of the drone through the connecting member 13, the load exerts pressure on the load plate 12. Add a downward pulling force, and the elastic member 11 applies a downward elastic force to the load plate 12. If the center of the UAV is offset, the load plate 12 will tilt, and the load plate 12 will apply pressure to the first sensing parts 30 on the side of the cantilever 21 in different tilt directions. Different first sensing parts 30 can sense the pressure applied by the load plate 12 in different tilt directions and output corresponding pressure values. Subsequently, the center of gravity position of the UAV can be calculated according to the pressure values ​​in different tilt directions, and then the posture of the UAV can be adjusted according to the center of gravity position to prevent the UAV from losing balance.

[0037] The detection device for a drone of this embodiment improves the method of adjusting the flight posture of the drone. By setting a first sensing part to detect the pressure value in the tilt direction, the current center of gravity position of the drone is determined according to the pressure values ​​in each tilt direction, and then the current flight posture of the drone is determined according to the current center of gravity position of the drone to adjust its flight posture. Different from the prior art method of using a physical sliding device to adjust the position of the load, the detection device of this embodiment detects pressure through the first sensing part, and there is no need to set a physical sliding device with a complex structure, which is conducive to simplifying the structure of the drone.

[0038] As an optional embodiment, the detection device 100 for a drone of this embodiment further includes: a second sensing unit 40, wherein a plurality of second sensing units 40 are provided, and the plurality of second sensing units 40 are respectively provided on a plurality of fixing units 20 in a one-to-one correspondence, and the second sensing unit 40 is provided on the side of the protruding arm 22 facing the load plate 12, that is, the second sensing unit 40 is located between the protruding arm 22 and the load plate 12, and the second sensing unit 40 is used to detect the pressure applied by the load plate 12 along the extension direction of the cantilever 21. When the load is suspended at the bottom of the drone through the connecting member 13, the load applies a downward pulling force to the load plate 12, and the elastic member 11 applies a downward elastic force to the load plate 12. The load plate 12 applies pressure to the second sensing unit 40 along the extension direction of the cantilever 21, and the second sensing unit 40 outputs a pressure value. Subsequently, the load of the drone can be calculated according to different pressure values, and then the flight time of the drone can be calculated according to the load and the remaining power of the drone.

[0039] In the above embodiment, on the basis of setting the first sensing part 30, a second sensing part 40 is set up which can detect the pressure value along the extension direction of the cantilever 21, so as to measure the load of the UAV, and then calculate the flight time of the UAV, and then match the appropriate flight time according to the flight distance of the mission, which is beneficial to improve the efficiency and safety of the use of the UAV.

[0040] As an alternative implementation, see Figure 3 As shown, the detection device 100 for a drone of this embodiment further includes a processing module 50, which is communicatively connected to each first sensing unit 30. The processing module 50 is configured to obtain current posture adjustment data of the drone based on the first pressure data transmitted by each first sensing unit 30. Furthermore, the processing module 50 is further configured to transmit the obtained current posture adjustment data to the main control module 60 of the drone, so that the main control module 60 generates a corresponding current posture adjustment signal based on the received current posture adjustment data.

[0041] As an optional embodiment, the processing module 50 in this embodiment is further configured to obtain the current payload data of the drone based on the second pressure data transmitted by the second sensing unit 40. Furthermore, the processing module 50 is further configured to transmit the obtained current payload data to the drone's main control module 60, so that the main control module 60 can determine the drone's flight time based on the received current payload data. Furthermore, the current payload data is calculated by obtaining the second pressure data from each second sensing unit 40 and calculating the arithmetic average of the multiple second pressure data as the drone's current payload data.

[0042] As an optional embodiment, the first sensing unit 30 in this embodiment includes a first pressure sensor, and the second sensing unit 40 in this embodiment includes a second pressure sensor. Specifically, the first pressure sensor and the second pressure sensor can each be a flexible pressure sensor, and the flexible pressure sensor includes a MEMS (Microelectro Mechanical Systems) sensor.

[0043] Specifically, the processing module 50 can be a microprocessor that supports multi-channel sampling. The microprocessor is respectively connected to multiple first sensing parts 30, and can process the collected first pressure data and send it to the main control module 60; at the same time, the microprocessor is connected to multiple second sensing parts 40, and can process the collected second pressure data and send it to the main control module 60.

[0044] As an optional embodiment, the plurality of fixing portions 20 are evenly arranged at preset intervals along the circumference of the load plate 12 .

[0045] As a specific implementation method, please continue to refer to Figure 1 As shown, the load plate 12 is a rounded rectangular shape, comprising four straight sides 121 and four rounded corners 122 connecting two adjacent straight sides 121. Accordingly, there are four fixing portions 20, each corresponding to one of the four rounded corners 122. Accordingly, four first sensing portions 30 are located at each of the four rounded corners 122. When the center of gravity of the load shifts, the load plate 12 tilts, and the rounded corners 122 of the load plate 12 located in the tilted direction apply pressure to the corresponding first sensing portion 30. Furthermore, the load plate 12 is a rounded square shape.

[0046] As another specific implementation, see Figure 4As shown, the load plate 12 is rectangular, and the load plate 12 includes four straight edges 123 and four diagonal corners 124 respectively connecting two adjacent straight edges 123. The number of the fixing parts 20 is four, and the four fixing parts 20 are respectively arranged corresponding to the midpoints of the four straight edges 123. Correspondingly, the four first sensing parts 30 are respectively arranged at the midpoints of the four straight edges 123.

[0047] As an optional embodiment, the elastic member 11 may be a spring.

[0048] As an optional embodiment, the connecting member 13 may be a hook for connecting a load.

[0049] As an optional embodiment, the load plate 12 is arranged perpendicular to the elastic member 11, which is beneficial to improving the structural stability of the load-bearing part 10. Accordingly, the first sensing part 30 is used to detect the pressure applied by the load plate 12 in a direction perpendicular to the cantilever 21.

[0050] An embodiment of the present application provides a drone. Figure 5 As shown, the drone 200 includes a body 201 and a detection device 100 for the drone provided on the body 201. The body 201 includes a rotor assembly 202. The specific details of the drone detection device 100 are described in the above embodiment and will not be described in detail here.

[0051] The drone of this embodiment is provided with a detection device 100 for the drone. By setting a plurality of first sensing parts to collect the pressure in different directions applied by the load plate, the center of gravity of the drone is adjusted according to the collected pressure, which is conducive to simplifying the structure of the drone.

[0052] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
