[0054] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0055] Drone is a general term for unmanned aerial vehicles, which are unmanned aerial vehicles controlled by radio remote control equipment and self-contained program control devices. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. Compared with manned aircraft, it has the advantages of small size, low cost, easy use, low requirements for the working environment, and strong survivability. It has a wide range of applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, etc.

[0056] With the continuous expansion of drone application fields, drones are playing an important role in all walks of life. Since most drones fly and work in outdoor environments, in order to facilitate the transportation of drones to outdoor venues, there are higher requirements for the carrying size of drones.

[0057] Since the positioning device located on the fuselage of the drone needs to be protruding from the upper surface of the fuselage without any shielding around it, and the existing positioning device is generally fixed on the fuselage, the positioning device will increase the carrying size of the drone.

[0058] In order to solve at least one of the technical problems existing in the prior art or related art, the utility model provides a positioning device. When using the positioning device, it is only necessary to rotate the support part to a preset position, and the locking assembly locks the support part on the mounting seat to fix the support part at the preset position. When carrying and transporting the drone, the locking assembly locks the support part on the mounting seat, and then the support part is rotated relative to the mounting seat to fold the support part on the drone body, so as to reduce the transportation size of the drone equipped with the positioning device.

[0059] The following describes a positioning device and a drone according to some embodiments of the present invention with reference to the accompanying drawings.

[0060] See also Figures 1 to 5 A positioning device according to an embodiment of the present invention is applied to a UAV, and the positioning device comprises a shell 1, a mounting seat 2, a support portion 3 and a locking assembly 4. A positioning module 5 is arranged in the shell 1; the mounting seat 2 is used to be installed on the UAV, and the mounting seat 2 is connected to the avionics module 6 of the UAV; the first end of the support portion 3 is connected to the shell 1, and the second end of the support portion 3 is hinged to the mounting seat 2; the locking assembly 4 is used to unlock the support portion 3 on the mounting seat 2 after the support portion 3 is rotated to a preset position.

[0061] The preset position here may be a position where the support portion 3 is perpendicular to the upper surface of the fuselage 9 of the drone.

[0062] It should be noted that the positioning module 5 and the avionics module 6 can be connected via a line 7, and one end of the line 7 can be connected to the positioning module 5, and the other end can be connected to the avionics module 6 after passing through the support portion 3 and the mounting seat 2 in sequence. Here, the support portion 3 can be a carbon fiber tube with a hollow structure, so that the line 7 can pass through the hollow structure of the carbon fiber tube, so that there is no visible line on the surface of the positioning device.

[0063] Here, the positioning module 5 may be an avionics GPS board for realizing the GPS receiving / transmitting signal function; the housing 1 may be made of POM plastic. The avionics module 6 may be a module derived from the flight control module and specifically connected to the positioning module 5 .

[0064] In this embodiment, when using the positioning device, it is only necessary to rotate the support portion 3 to a preset position and lock the support portion 3 on the mounting seat 2 through the locking assembly 4 to fix the support portion 3 at the preset position (such as Figure 1When the UAV is carried and transported, the locking assembly 4 is released to lock the support portion 3 on the mounting seat 2, and then the support portion 3 is rotated relative to the mounting seat 2 to fold the support portion 3 on the fuselage 9 of the UAV (as shown). Figure 5 As shown), the transport size of the UAV equipped with the positioning device can be reduced to improve the transport efficiency of the UAV; the positioning device provided by the utility model can be quickly assembled, which is beneficial to reducing the carrying size of the UAV and improving the convenience of UAV transportation.

[0065] In some possible embodiments, the second end of the support portion 3 is hinged to the mounting seat 2 through a hinge assembly 8, and the hinge assembly 8 includes a hinge hole 801, a hinge seat 802 and a hinge shaft 803, and the hinge hole 801 is opened on the mounting seat 2; the hinge seat 802 is connected to the second end of the support portion 3; the hinge shaft 803 is connected to the hinge seat 802, and the hinge shaft 803 is also movably connected to the hinge hole 801 so that the hinge seat 802 rotates around the hinge shaft 803.

[0066] It should be noted that an elastic rubber pad 804 is provided in the hinge hole 801 in this embodiment. After the hinge shaft 803 passes through the hinge hole 801, the elastic rubber pad 804 is mounted on the hinge shaft 803, so that the hinge shaft 803 and the hinge hole 801 are connected through the elastic rubber pad 804, thereby avoiding the existence of a gap at the connection between the hinge shaft 803 and the hinge hole 801, so as to achieve the connection stability between the hinge shaft 803 and the hinge hole 801.

[0067] Exemplarily, two relatively arranged hinge holes 801 are opened on the mounting seat 2, and a through hole is provided on the hinge seat 802. The hinge shaft 803 is matched with the hinge hole 801 and the through hole on the hinge seat 802 to realize the hinge connection between the hinge seat 802 and the mounting seat 2, so that the support part 3 rotates with the hinge seat 802 around the hinge shaft 803.

[0068] Here, the hinge shaft 803 and the hinge hole 801 , as well as the hinge shaft 803 and the hinge seat 802 , can be detachably connected.

[0069] In this embodiment, the second end of the support portion 3 is hinged to the mounting seat 2 through the hinge assembly 8, that is, the hinge shaft 803 is connected with the hinge hole 801 provided on the mounting seat 2 and the hinge seat 802 provided at the second end of the support portion 3, so that the second end of the support portion 3 and the mounting seat 2 can be hinged, and the support portion 3 can be rotated with the rotation of the hinge seat 802 around the hinge shaft 803, so that the support portion 3 can be folded relative to the fuselage 9 of the drone by controlling the rotation angle of the hinge seat 802 relative to the mounting seat 2 fixed on the drone fuselage 9, see Figure 5 .

[0070] Furthermore, the hinge assembly 8 also includes a limiting portion 805, which is located on the mounting seat 2. After the support portion 3 rotates to a preset position along with the hinge seat 802, the limiting portion 805 contacts the side of the hinge seat 802 to limit the rotation of the support portion 3 on the mounting seat 2.

[0071] Exemplarily, the limiting portion 805 here can be a limiting wall arranged near one end of the mounting seat 2 and the support portion 3. After the support portion 3 rotates to a preset position along with the hinge seat 802, a side portion of the limiting wall near the hinge seat 802 contacts the hinge seat 802, limiting the hinge seat 802 from continuing to rotate in the direction of the limiting wall, thereby limiting the support portion 3 from rotating on the mounting seat 2.

[0072] In this embodiment, a limit portion 805 is provided on the mounting seat 2, so that after the support portion 3 rotates to the preset position along with the hinge seat 802, the limit portion 805 limits the rotation of the hinge seat 802, and then the support portion 3 stops rotating after rotating to the preset position, so that the support portion 3 can be fixed at the preset position through the locking assembly 4.

[0073] In some possible embodiments, the locking assembly 4 includes a socket 401, a connector 402 and a driving unit, the socket 401 is connected to the support portion 3, and a connector hole 403 is provided on the socket 401; the connector 402 is movably connected to the mounting seat 2, and the connector 402 has a first position and a second position on the mounting seat 2; the driving unit is connected to the connector 402, and is used to drive the connector 402 to reciprocate between the first position and the second position; when the connector 402 is in the first position, the connector 402 is plugged into the connector hole 403 to lock the support portion 3 on the mounting seat 2; when the connector 402 is in the second position, the connector 402 can be disengaged from the connector hole 403 to release the lock of the support portion 3 on the mounting seat 2.

[0074] Here, the socket 401 can be arranged on the hinge seat 802 to realize the connection between the socket 401 and the support part 3. The axial direction of the socket 403 is parallel to the length direction of the support part 3, and after the support part 3 moves to the preset position, the axis of the socket 403 and the axis of the connector 402 are located on the same straight line.

[0075] For example, the mounting seat 2 is provided with a placement cavity, the plug-in component 402 is located in the placement cavity, and when the support portion 3 is moved to the preset position, the axis of the placement cavity and the axis of the plug-in hole 403 are located on the same straight line. When the positioning device is needed, the support portion 3 is moved to the preset position, and then the plug-in component 402 is driven by the driving portion to move to the first position, and the plug-in component 402 can be plugged into the plug-in hole 403 to achieve the locking of the support portion 3 on the mounting seat 2; Figure 5As shown, when the positioning device needs to be folded, the driving part drives the connector 402 to move to the second position, and the connector 402 can be disengaged from the plug hole 403, thereby unlocking the support part 3 on the mounting base 2, and then the support part 3 is rotated relative to the mounting base 2 until the support part 3 moves to its storage position.

[0076] In this embodiment, by connecting the socket 401 with the support portion 3, and providing a connector 402 that can move on the mounting base 2 on the mounting base 2, and then driving the connector 402 to reciprocate between the first position and the second position by the driving portion, the connector 402 can be controlled by the driving portion to be connected or disconnected from the socket 403, thereby achieving the support portion 3 in the preset position being unlockably locked on the mounting base 2.

[0077] Furthermore, the driving part includes an elastic member and a control member 405. The elastic member is arranged on the mounting seat 2 and is connected to the connector 402. When the elastic member is in an uncompressed state, the connector 402 is located at a first position. When the elastic member is in a compressed state, the connector 402 is located at a second position. The control member 405 is used to control the compression or extension of the elastic member to control the connector 402 to reciprocate between the first position and the second position.

[0078] Here, the elastic member may be a spring, which may be arranged in the placement cavity and located below the plug connector 402 and connected to the bottom of the plug connector 402, and the control member 405 may be connected to the top of the elastic member. When no force is applied to the control member 405, the elastic member is not compressed, and at this time, the elastic member is in an extended state, and the plug connector 402 is at the first position; when a force is applied to the control member 405 along the compression direction of the elastic member, the elastic member is in a compressed state, and the plug connector 402 is at the second position.

[0079] In this embodiment, by providing an elastic member connected to the connector 402 on the mounting seat 2, a force can be applied to the elastic member through the control member 405, so that the connector 402 can be reciprocated between the first position and the second position under the elastic action of the elastic member, and then the locking or unlocking control of the locking assembly 4 can be achieved by applying a force to the control member 405.

[0080] For further information, see Figure 2The connector 402 includes a plug-in boss 4022 and a connecting rod 4021 that are connected to each other. The plug-in boss 4022 and the connecting rod 4021 are coaxially arranged, and one end of the connecting rod 4021 away from the plug-in boss 4022 is connected to the control member 405; the elastic member includes a return spring 404, and the return spring 404 is sleeved on the connecting rod 4021, one end of the return spring 404 abuts against the plug-in boss 4022, and the other end of the return spring 404 abuts against the mounting seat 2; when the control member 405 does not drive the connecting rod 4021 to move, so that the return spring 404 is in an uncompressed state, the plug-in boss 4022 can be plugged into the plug-in hole 403; when the control member 405 drives the connecting rod 4021 to move, so that the return spring 404 is in a compressed state, the plug-in boss 4022 can be separated from the plug-in hole 403.

[0081] Here, the return spring 404 may be a coil spring; and the control member 405 may be a pull ring connected to the bottom of the connecting rod 4021 .

[0082] In this embodiment, by sleeved the reset spring 404 on the connecting rod 4021, and then connecting the control member 405 to the end of the connecting rod 4021 away from the plug-in boss 4022, it is possible to achieve that by applying a force to the control member 405 to move the plug-in boss 4022 away from the plug-in hole 403, the plug-in boss 4022 can be disengaged from the plug-in hole 403, thereby completing the unlocking of the support portion 3 at the preset position; at the same time, when it is necessary to fix the support portion 3 at the preset position, it is necessary to apply a force to the control member 405 to move the plug-in boss 4022 away from the plug-in hole 403 during the process of rotating the support portion 3 to the preset position, and then when the support portion 3 is rotated to the preset position, the force applied by the control member 405 is released, so that the connector 402 moves to the first position under the elastic action of the reset spring 404, thereby achieving the plugging of the connector 402 to the plug-in hole 403.

[0083] In some possible embodiments, the mounting base 2 includes a connecting portion 201, a fixing portion 202 and a plug-in module 203; the second end of the supporting portion 3 is hinged to the connecting portion 201; after the supporting portion 3 is rotated to a preset position, the axis of the supporting portion 3 and the axis of the connecting portion 201 are located on the same straight line; the fixing portion 202 is detachably connected to the connecting portion 201, and the fixing portion 202 is detachably connected to the fuselage 9 of the UAV; the plug-in module 203 is connected to the bottom of the fixing portion 202; after the fixing portion 202 is connected to the fuselage 9 of the UAV, the plug-in module 203 is used to plug in the avionics module 6.

[0084] Here, the connecting portion 201 and the fixing portion 202 are detachably connected by bolts; and the plug-in module 203 is detachably connected to the bottom of the fixing portion 202 by bolts.

[0085] It should be noted that see Figure 4The fuselage 9 of the UAV is provided with an installation opening 901 , the plug-in module 203 is arranged on the installation opening 901 , and the fuselage 9 of the UAV is provided with a connecting hole 902 for connecting with the fixing part 202 near the installation opening 901 .

[0086] Furthermore, the line 7 connected to the positioning module 5 passes through the supporting portion 3 , the connecting portion 201 and the fixing portion 202 in sequence and is connected to the plug-in module 203 .

[0087] Here, the line 7 may be connected to the plug-in module 203 by welding.

[0088] In this embodiment, the line 7 connected to the positioning module 5 is connected to the plug-in module 203 by passing through the support part 3, the connecting part 201 and the fixing part 202 in sequence to avoid the line 7 being exposed to the outside of the positioning device, so that there is no visible line on the outer surface of the fuselage 9 installed with the positioning device, thereby increasing the beauty of the fuselage 9.

[0089] In some possible embodiments, the shell 1 includes an upper shell 101 and a lower shell 102 that can be snapped together; after the upper shell 101 and the lower shell 102 are snapped together, a receiving cavity for placing the positioning module 5 is formed between the upper shell 101 and the lower shell 102.

[0090] Here, by disposing the positioning module 5 in the accommodating cavity formed by the upper shell 101 and the lower shell 102 , the positioning module 5 can be protected, which is beneficial to prolonging the service life of the positioning device.
