Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV-mounted detection device and a UAV. Background Art

[0002] With the development of technology, drones are increasingly used in the logistics and transportation field. Drones are usually used for transportation by suspending cargo boxes. Drones need to be equipped with corresponding aircraft rails and hooks to suspend the cargo boxes. The fit between the cargo box and the hook, as well as the fit between the aircraft rail and the cargo box, will affect the safe suspension of the cargo box. However, the current technology cannot accurately determine whether the cargo box is in a safe suspension state, which leads to certain safety hazards in the use of drones and reduces the safety of drone transportation. Summary of the Invention

[0003] This application provides a drone-mounted detection device and a drone, which solves the problem that drones cannot detect whether cargo boxes are safely mounted.

[0004] This application provides a drone mounting detection device, including a main body and a detection unit. The main body is connected to the drone. The detection unit is mounted on the main body and is rotatable relative to the main body. At least a portion of the detection unit can extend into a cargo box for suspending the cargo box and detecting whether the cargo box is in a safe mounting state. The detection unit includes a body portion, a trigger, and a button. Both the trigger and the button are mounted on the body portion. The trigger is rotatable relative to the body portion and can abut against the cargo box. When the trigger abuts against the cargo box, the trigger rotates towards the button to trigger the button. The button can be used to detect signals.

[0005] In one possible implementation, the detection unit further includes a mounting shaft, the trigger having a first mounting hole, the body having a second mounting hole, and at least a portion of the mounting shaft being able to extend into the first mounting hole and the second mounting hole for rotatably connecting the trigger to the body.

[0006] In one possible implementation, the body portion has a first receiving groove and a second receiving groove. The first receiving groove extends along the thickness direction of the body portion. The button is located in the first receiving groove. The second receiving groove communicates with the first receiving groove. The trigger is located in the second receiving groove. A portion of the trigger is located outside the second receiving groove. The trigger is rotatable relative to the first and second receiving grooves.

[0007] In one possible implementation, the trigger includes a recess and an extension, the extension being connected to the recess and located in the first receiving groove. The extension is capable of abutting against the button. The recess is recessed to a side away from the main body, and a portion of the recess is located outside the second receiving groove. The recess is capable of abutting against the cargo box. When the recess abuts against the cargo box, the trigger is capable of rotating relative to the main body, and the extension is capable of abutting against the button.

[0008] In one possible implementation, the key includes a key core, a keycap, and an elastic element. The elastic element is sleeved on the key core and connected to the keycap. When the extension abuts against the keycap, the elastic element can be compressed; when the extension does not abut against the keycap, the elastic element can remain in its original length.

[0009] In one possible implementation, the key further includes a housing, the key core and the elastic element are both located in a receiving cavity formed by the housing, and the keycap covers the housing.

[0010] In one possible implementation, the detection unit further includes a connecting part, which is fixedly connected to the main body. The connecting part is provided with a first connecting rod, and the detection unit is rotatably connected to the main body through the first connecting rod. The detection unit also includes a rotating shaft, which is sleeved with the connecting part. When the first connecting rod rotates, the connecting part drives the main body to rotate relative to the rotating shaft.

[0011] In one possible implementation, the main body includes a second link, one end of which is connected to the first link. The UAV is equipped with a servo motor, which has an output shaft. The other end of the second link is connected to the output shaft, and the servo motor is capable of driving the second link to rotate.

[0012] In one possible implementation, the button is provided with an interface, through which the button is electrically connected to the UAV, for outputting the detection signal of the UAV-mounted detection device to the UAV.

[0014] This application provides a drone mounting detection device and a drone, including a main body and a detection unit. The main body is connected to the drone, and the detection unit is installed on the main body and can rotate relative to the main body. At least a portion of the detection unit can extend into a cargo box for suspending the cargo box and detecting whether the cargo box is in a safe mounting state. The detection unit includes a body, a trigger, and a button. Both the trigger and the button are installed on the body. The trigger can rotate relative to the body and can abut against the cargo box. When the trigger abuts against the cargo box, it rotates towards the button to trigger it. The button outputs a detection signal.

[0050] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0051] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0053] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0054] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0055] like Figure 1 and Figure 2 As shown, this application embodiment provides a drone mounting detection device, including a main body 1 and a detection unit 2. The main body 1 is connected to the drone, and the detection unit 2 is installed on the main body 1 and can rotate relative to the main body 1. At least a portion of the detection unit 2 can extend into the cargo box 3 for suspending the cargo box 3 and detecting whether the cargo box 3 is in a safe mounting state. The detection unit 2 includes a body 21, a trigger 22, and a button 23. The trigger 22 and the button 23 are both installed on the body 21. The trigger 22 can rotate relative to the body 21 and can abut against the cargo box 3. When the trigger 22 abuts against the cargo box 3, the trigger 22 rotates towards the button 23 to trigger the button 23. The button 23 is used to output a detection signal.

[0056] The drone-mounted detection device can be used on drones. During drone logistics transportation, a cargo box 3 is typically suspended from the drone for handling. The drone-mounted detection device can be used to suspend the cargo box 3 and detect whether it is in a safe mounting state. The drone-mounted detection device includes a main body 1 and a detection part 2. One end of the main body 1 is connected to the drone, and the other end is connected to the detection part 2. At least a portion of the detection part 2 can extend into the cargo box 3, and the detection part 2 can also rotate relative to the main body 1, i.e., the detection part 2 is rotatably connected to the main body 1, thus facilitating the flexible entry and exit of the detection part 2 from the cargo box 3. Specifically, the detection part 2 can be a hook-like structure, and the cargo box 3 typically has a circular hole 31, through which at least a portion of the detection part 2 can extend into the cargo box 3. When the cargo box 3 needs to be transported, the drone can control the drone-mounted detection device to rotate, causing the detection part 2 to extend into the circular hole 31 of the cargo box 3, thereby suspending the cargo box 3 during drone operation. Simultaneously, the detection unit 2 can also detect whether the cargo box 3 is in a safe mounting state. Specifically, the detection unit 2 includes a main body 21, a trigger 22, and a button 23. The trigger 22 and the button 23 are both installed on the main body 21, and the button 23 is located on the side of the trigger 22 away from the main body 1. The trigger 22 can rotate relative to the main body 21, and one end of the trigger 22 can abut against the button 23, thereby triggering the button 23. When at least a portion of the detection unit 2 extends into the circular hole 31 of the cargo box 3, the cargo box 3 can abut against the trigger 22. Under the action of the gravity of the cargo box 3, the trigger 22 can rotate relative to the main body 21, that is, the trigger 22 rotates towards the button 23, so that the trigger 22 can abut against the button 23, thereby triggering the button 23. When button 23 is triggered, the drone load detection device can detect that the cargo box 3 is in a safe load state and output the detection result. Specifically, the detection result can be fed back to the drone, so that the drone can know the specific load state of the cargo box 3, which helps to ensure the safety of drone flight transportation. Correspondingly, when the drone load detection device can detect that the cargo box 3 is not in a safe load state, it can also feed back the detection result to the drone.

[0057] In existing technologies, drones transport cargo boxes 3 by setting up corresponding aircraft rails and hooks. The hooks can cooperate with the round holes 31 on the cargo boxes 3 to suspend the cargo boxes 3, and the aircraft rails can stabilize and fix the cargo boxes 3. However, the position of the round holes 31 on the cargo boxes 3, the cooperation between the hooks and the round holes 31 on the cargo boxes 3, and the cooperation between the aircraft rails and the cargo boxes 3 all affect the stability of the cargo boxes 3. These problems all need to be solved by manual inspection, which is not only not conducive to the automation of drone transportation, but also poses certain safety hazards, thereby reducing the safety of drone transportation.

[0058] This embodiment of the application sets up a drone-mounted detection device, so that the detection unit 2 can play both a detection role and a suspension role. This not only realizes the drone's transportation function, but also facilitates the detection of whether the cargo box 3 is in a safe mounting state, reducing the possibility of using manual inspection. At the same time, the detection results can be fed back to the drone in a timely manner. This setting helps to improve the safety of cargo box 3 transportation, reduce safety hazards, and thus improve the safety of drone flight.

[0059] like Figures 3 to 5 As shown, in one possible implementation, the detection unit 2 further includes a mounting shaft 24, the trigger member 22 has a first mounting hole 221, the body part 21 has a second mounting hole 211, and at least a portion of the mounting shaft 24 can extend into the first mounting hole 221 and the second mounting hole 211 for rotatably connecting the trigger member 22 and the body part 21.

[0060] The detection unit 2 also includes a mounting shaft 24. One end of the trigger 22 has a first mounting hole 221, and one end of the main body 21 has a second mounting hole 211. The first mounting hole 221 and the second mounting hole 211 are connected. The mounting shaft 24 can extend into the first mounting hole 221 and the second mounting hole 211 to rotatably connect the trigger 22 and the main body 21. Specifically, under the action of the gravity of the cargo box 3, the trigger 22 can rotate the mounting shaft 24 as a rotating shaft, thereby triggering the button 23.

[0061] By setting the mounting shaft 24, it is easier to realize the rotational connection between the trigger element 22 and the main body 21, which makes it easier for the trigger element 22 to trigger the button 23, thereby facilitating the detection function of the detection unit 2, and also improving the stability of the installation of the trigger element 22.

[0062] like Figure 4As shown, in one possible embodiment, the body portion 21 has a first receiving groove 212 and a second receiving groove 213. The first receiving groove 212 extends along the thickness direction of the body portion 21. The button 23 is located in the first receiving groove 212. The second receiving groove 213 communicates with the first receiving groove 212. The trigger member 22 is located in the second receiving groove 213. A part of the trigger member 22 is located outside the second receiving groove 213, and the trigger member 22 is rotatable relative to the first receiving groove 212 and the second receiving groove 213.

[0063] The main body 21 has a first receiving groove 212 and a second receiving groove 213. The first receiving groove 212 can communicate with the second receiving groove 213. The first receiving groove 212 extends along the thickness direction of the main body 21, and the button 23 is installed in the first receiving groove 212. The trigger member 22 is located in the second receiving groove 213, and a part of the trigger member 22 is located outside the second receiving groove 213, so that the trigger member 22 can abut against the cargo box 3. The trigger member 22 can move relative to the first receiving groove 212 and the second receiving groove 213.

[0064] By setting the first receiving groove 212 and the second receiving groove 213, it is beneficial to accommodate the button 23 and the trigger 22, thereby saving the space occupied by the button 23 and the trigger 22. This is beneficial to the cooperation between the detection unit 2 and the round hole 31 of the cargo box 3, and reduces the possibility of interference between the cargo box 3 and the button 23, which is conducive to realizing the detection function of the detection unit 2.

[0065] like Figure 5 and Figure 6 As shown, in one possible embodiment, the trigger 22 includes a recess 222 and an extension 223 connected to the recess 222. The extension 223 is located in the first receiving groove 212 and can abut against the button 23. The recess 222 is recessed to the side away from the main body 1, and a portion of the recess 222 is located outside the second receiving groove 213. The recess 222 can abut against the cargo box 3. When the recess 222 abuts against the cargo box 3, the trigger 22 can rotate relative to the main body 21, and the extension 223 can abut against the button 23.

[0066] The trigger 22 includes a recess 222 and an extension 223. The extension 223 is located in the first receiving groove 212 and can abut against the button 23. The recess 222 is connected to the extension 223 and is recessed towards the side away from the main body 1, and can abut against the cargo box 3. Specifically, when the detection unit 2 suspends the cargo box 3, a portion of the recess 222 is located outside the second receiving groove 213, so the cargo box 3 can abut against the recess 222. The trigger 22 is rotated towards the button 23 by the gravity of the cargo box 3, so that the extension 223 can abut against the button 23. Under the action of the extension 223, the button 23 can be triggered. At this time, the detection unit 2 can detect that the cargo box 3 is in the installed and mounted state and can feed back the detection result to the drone.

[0067] The recessed portion 222 helps improve the stability of the cargo box 3 suspended by the detection unit 2, reduces the possibility of the cargo box 3 falling off the detection unit 2, and thus helps improve the safety and stability of UAV transportation. The extension portion 223 facilitates the triggering of the button 23, which helps to realize the detection function of the detection unit 2, and also helps to reduce the possibility of the button 23 being accidentally touched, thus helping to improve the detection accuracy of the detection unit 2.

[0068] like Figure 3 As shown, in one possible implementation, the key 23 includes a key core 231, a keycap 232, and an elastic member 233. The elastic member 233 is sleeved on the key core 231 and connected to the keycap 232. When the extension 223 abuts against the keycap 232, the elastic member 233 is compressed; when the extension 223 does not abut against the keycap 232, the elastic member 233 is in its original length state.

[0069] The button 23 may include a keycap 232, a key core 231, and an elastic element 233, wherein the elastic element 233 is sleeved on the key core 231 and connected to the keycap 232. Specifically, the elastic element 233 may be a spring, and the keycap 232 may be a silicone keycap 232, which helps to improve the waterproof performance of the button 23. When the trigger 22 abuts against the housing 3, the extension 223 abuts against the keycap 232, thereby triggering the button 23. Due to the gravity of the housing 3, the elastic element 233 is in a compressed state at this time. When the housing 3 leaves the detection unit 2, the elastic element 233 is no longer subjected to the gravity of the housing 3, and can thus return to its original length. The keycap 232 is bounced up under the action of the elastic element 233, and the trigger 22 rotates away from the button 23 under the action of the elastic element 233, and the button 23 can return to its initial state.

[0070] By setting the elastic element 233, it is beneficial to realize the reset function of button 23 and trigger 22, which facilitates the repeated use of detection unit 2, improves the detection accuracy of detection unit 2, reduces the possibility of button 23 being accidentally touched, and thus helps to improve the safety of UAV transportation.

[0071] like Figure 3 As shown, in one possible implementation, the key 23 further includes a housing 234, the key core 231 and the elastic element 233 are both located in the receiving cavity formed by the housing 234, and the keycap 232 covers the housing 234.

[0072] The key 23 includes a housing 234, a key core 231, and an elastic element 233, all located in the receiving cavity formed by the housing 234. The keycap 232 can cover the housing 234. The key 23 may also include an upper housing 235, which is located in the receiving cavity of the housing 234 and is installed on the key core 231.

[0073] By providing the outer casing 234, the key core 231 is protected, which helps to extend the service life of the key 23, thereby extending the service life of the detection unit 2 and ultimately improving the detection function of the detection unit 2.

[0074] like Figure 4 As shown, in one possible implementation, the detection unit 2 further includes a connecting part 25, which is fixedly connected to the main body 21. The connecting part 25 is provided with a first connecting rod 251. The detection unit 2 is rotatably connected to the main body 1 through the first connecting rod 251. The detection unit 2 also includes a rotating shaft 26, which is sleeved with the connecting part 25. When the first connecting rod 251 rotates, the connecting part 25 drives the main body 21 to rotate relative to the rotating shaft 26.

[0075] The detection unit 2 also includes a connecting part 25, which is fixedly connected to the main body 21. The connecting part 25 is provided with a first connecting rod 251, which is rotatably connected to the main body 1. The main body 1 can drive the first connecting rod 251 to rotate. When the first connecting rod 251 rotates, it can drive the detection unit 2 to rotate, thereby controlling the detection unit 2 to enter and exit the circular hole 31 of the cargo box 3, facilitating the loading or unloading of the cargo box 3. The detection unit 2 may also include a rotating shaft 26, which is sleeved with the connecting part 25, allowing the connecting part 25 to rotate using the rotating shaft 26 as a pivot.

[0076] like Figure 3 As shown, in one possible implementation, the main body 1 includes a second link 11, one end of which is connected to the first link 251. The UAV is equipped with a servo motor 4, which has an output shaft 41. The other end of the second link 11 is connected to the output shaft 41. The servo motor 4 can drive the second link 11 to rotate.

[0077] The main body 1 includes a second link 11. One end of the first two links is connected to the first two links, and the other end is connected to the output shaft 41 of the UAV servo motor 4. The servo motor 4 can drive the second link 11 to rotate, thereby causing the second link 11 to drive the first link 251 to rotate, thus realizing the rotation of the detection unit 2.

[0078] This configuration facilitates the rotation of the control and detection unit 2, which in turn facilitates the mounting or unloading of the cargo box 3, enables the detection unit 2 to perform inspections on the cargo box 3, and ultimately benefits the logistics and transportation of the UAV.

[0079] like Figure 6 As shown, in one possible implementation, button 23 is provided with interface 236, and button 23 is electrically connected to the UAV through interface 236 to output detection signals of the UAV-mounted detection device to the UAV.

[0080] Button 23 can output a detection signal to the drone through the button signal recognition principle. Specifically, the button can be electrically connected to the drone's motherboard through interface 236. When the detection unit 2 detects that the cargo is in a safe mounting state, button 23 can output a corresponding detection signal to the drone through interface 236. After receiving the safe mounting detection signal of the cargo box 3, the drone performs a self-test and can then feed the detection signal back to the ground terminal. More specifically, the drone can feed the detection signal back to the ground terminal via 4G or 5G signals, allowing the operator to understand the mounting status of the cargo box 3, thus facilitating drone operation for transportation. Conversely, the drone mounting device can also feed back the detection result of the cargo box 3 not being in a safe mounting state to the drone, further improving the safety of drone use. In another embodiment, button 23 can simultaneously feed back the detection result to both the ground terminal and the drone, allowing the operator to promptly understand the specific status of the cargo box 3.

[0081] By setting up an interface, it is beneficial to realize the function of detection signal feedback, which helps the UAV and the ground to judge the loading status of cargo box 3, so that the UAV can carry out transportation work when cargo box 3 is safely loaded, which helps to improve the safety of UAV transportation and reduce safety hazards.

[0082] This application embodiment also provides a drone, which may include at least two drone load detection devices as described above. The drone can be used for logistics transportation. Specifically, the drone can carry a cargo box 3 for transportation. The drone can be equipped with at least two drone load detection devices, which can be set on both sides of the cargo box 3. Only when all the buttons 23 of the drone load detection devices are triggered can it be determined that the cargo is in a safe load state, and the drone can pass the self-test. This setting further improves the stability and safety of the cargo box 3 load, and also improves the accuracy of the detection results of the drone load detection devices, thereby improving the safety of drone transportation.

[0083] This application provides a drone mounting detection device and a drone, including a main body 1 and a detection unit 2. The main body 1 is connected to the drone, and the detection unit 2 is installed on the main body 1 and can rotate relative to the main body 1. At least a portion of the detection unit 2 can extend into a cargo box 3 for suspending the cargo box 3 and detecting whether the cargo box 3 is in a safe mounting state. The detection unit 2 includes a body 21, a trigger 22, and a button 23. Both the trigger 22 and the button 23 are installed on the body 21. The trigger 22 can rotate relative to the body 21 and can abut against the cargo box 3. When the trigger 22 abuts against the cargo box 3, the trigger 22 rotates towards the button 23 to trigger the button 23. The button 23 is used to output a detection signal. This embodiment of the application sets up a drone-mounted detection device, so that the detection unit 2 can play both a detection role and a suspension role. This not only realizes the drone's transportation function, but also facilitates the detection of whether the cargo box 3 is in a safe mounting state, reducing the possibility of using manual inspection. At the same time, the detection results can be fed back to the drone in a timely manner. This setting helps to improve the safety of cargo box 3 transportation, reduce safety hazards, and thus improve the safety of drone flight.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
