[0038] The present invention will now be described in detail.

[0039] like Figures 1-9 As shown:

[0040] A take-off and landing platform for a drone 100 includes a base plate 1 and a centering mechanism mounted on the base plate 1 for centering and locking the drone 100.

[0041] The centering mechanism includes a centering component 1 2 mounted on the base plate 1 for controlling the movement of the UAV 100 along the Y-axis direction, and a centering component 2 3 mounted on the base plate 1 for controlling the movement and locking of the UAV 100 along the X-axis direction.

[0042] The centering component 2 includes two sets of centering beams 21 that are parallel to each other and arranged along the X-axis, and a centering drive component 22 that is in transmission cooperation with the two sets of centering beams 21 and is used to control the two sets of centering beams 21 to move closer or further apart along the Y-axis; the two sets of centering beams 21 are symmetrically arranged along the X-axis.

[0043] The centering component 2 3 is located between the two sets of centering beams 21 and is equidistant from the two sets of centering beams 21;

[0044] The centering component 2 3 includes two sets of locking components 31 with identical structures and symmetrically arranged along the Y-axis, and a centering drive component 2 32 that is in transmission cooperation with the two sets of locking components 31 and is used to control the two sets of locking components 31 to move closer or further apart along the X-axis.

[0045] When the UAV 100 is not docked on the base plate 1, the two sets of centering beams 21 and the two sets of locking components 31 will cooperate to form a large area. The locking components 31 will be located in the large area and the distance between them and the two sets of centering beams 21 will be equal.

[0046] After the UAV 100 lands in a large area, the centering drive component 22 first controls the two sets of centering beams 21 to move synchronously in a straight line along the X-axis direction and approach each other until the inner sides of the two sets of centering beams 21 respectively contact and abut against the landing gear of the UAV 100, thereby achieving the centering of the UAV 100 in the Y-axis direction.

[0047] Subsequently, the centering drive component 32 controls the two sets of locking components 31 to move synchronously in a straight line along the X-axis direction and approach each other until the inner sides of the two sets of locking components 31 respectively contact and abut against the landing gear of the UAV 100, thereby achieving centering and locking of the UAV 100 in the X-axis direction; through centering in the X-axis and Y-axis directions, the UAV 100 is then centered, docked, and locked on the base plate 1.

[0048] Furthermore, the landing gear of the UAV 100 includes a vertical bar 101 located at the bottom of the UAV 100 fuselage and a horizontal bar 102 connected to the vertical bar 101 and arranged along the Y-axis direction; there are two sets of horizontal bars 102, which are arranged along the Y-axis direction after landing on the base plate, and each set of horizontal bars 102 is connected to the bottom of the UAV 100 fuselage through two sets of vertical bars 101; when centering in the Y-axis direction, the two sets of centering beams 21 will contact and abut against the outer side of the vertical bar 101 and be located above the horizontal bar 102; when centering in the X-axis direction, the two sets of locking components 31 will contact and abut against the two sets of horizontal bars 102 on the opposite side.

[0049] Conversely, by controlling the two sets of centering beams 21 to move away from each other along the Y-axis through the centering drive component 1 22, and by controlling the two sets of locking components 31 to move away from each other along the X-axis through the centering drive component 2 32, the UAV 100 is no longer locked and can then take off.

[0050] The centering drive component 2 32 not only centeres the UAV 100 in the X-axis direction, but also fixes the UAV 100, making the operation simpler and more convenient.

[0051] In some possible implementations, in order to effectively enable the drone 100 to be charged after it has returned to its center and docked, the centering component 2 32 can also be used to avoid the plugging and unplugging operation for secondary charging, which would affect the docking position of the drone 100 due to the plugging and unplugging force; the centering component 2 3 also includes a plug component 33 that is disposed on one of the locking components 31 and works in conjunction with the socket component 1021 disposed on the landing gear of the drone 100.

[0052] The socket assembly 1021 is mounted on the crossbar 102 and located on the outside of the crossbar 102. The socket assembly 1021 is connected to the inside of the drone 100. The plug assembly 33 is located above the base plate 1 and the base plate 1 is slidably engaged. When the two sets of locking assemblies 31 approach each other along the X-axis, the plug assembly 33 will be inserted into the socket assembly 1021. After centering and locking, the plug assembly 33 and the socket assembly 1021 are fully inserted. The plug assembly 33 is connected to an external charger to charge the drone 100.

[0053] Furthermore, such as Figure 7 As shown, the socket assembly 1021 includes a socket housing 10211 mounted on a crossbar, a socket insulator 10212 mounted inside the socket housing 10211, and a socket female pin 10213 mounted on the socket insulator 10212; the socket female pin 10213 is connected to a battery on the drone body via a cable.

[0054] The plug assembly 33 includes a plug housing 331 installed between and connected to two sets of locking claws 312, a plug insulator 332 installed inside the plug housing 331, and a plug spring male pin 333 installed on the plug insulator 332 and inserted into the socket female pin 10213; the plug spring male pin 333 is connected to the charger via a cable.

[0055] Furthermore, to facilitate the guiding and docking of the locking claw 312 and the plug assembly 33, a guide rail 3122 is provided on the side of the locking claw 312 near the plug housing 331; a protrusion 334 that slides with the guide rail 3122 is provided on the outer side of the plug housing 331; a cavity 31221 that slides with the protrusion 334 along the X-axis direction is provided on the side of the guide rail 3122 near the plug housing 331; the cavity 31221 and the protrusion 334 are in clearance fit, so that the plug assembly 33 has a certain degree of flexibility.

[0056] In some possible implementations, in order to effectively achieve synchronous movement of the two sets of centering beams 21 along the Y-axis direction through the centering drive assembly 22, so as to move them closer or further apart; the centering drive assembly 22 includes two sets of bidirectional lead screws 221 symmetrically arranged along the Y-axis direction and rotating with the base plate 1, lead screw nuts 222 fitted on the outside of the bidirectional lead screws 221 and connected to both ends of each set of centering beams 21, and a drive device 223 that is driven by the two sets of bidirectional lead screws 221; the two sets of bidirectional lead screws 221 and the two sets of centering beams 21 cooperate to form a take-off and landing zone; the centering assembly 3 is located within the take-off and landing zone.

[0057] Each set of bidirectional lead screws 221 includes two sets of threaded segments with opposite thread directions and an intermediate section located between the two sets of threaded segments with opposite thread directions. The centering component 3 is located in the area formed by the two intermediate sections and the two sets of centering beams 21. Each set of threaded segments is connected to the end of the corresponding centering beam 21 through the lead screw nut 222. The thread directions of the threaded segments on the same side of the two sets of bidirectional lead screws 221 are the same.

[0058] During centering, drive device 223 is activated, synchronously driving two sets of bidirectional lead screws 221 to rotate around their axes. The two sets of bidirectional lead screws 221 rotate in the same direction, and drive four sets of lead screw nuts 222 to move along the axis of the corresponding bidirectional lead screw 221, thereby bringing the two sets of centering beams 21 closer to each other. The two sets of threads of each set of bidirectional lead screws 221 have opposite directions of rotation. The two sets of lead screw nuts 222 that cooperate with the bidirectional lead screw 221 include a left-hand lead screw nut that cooperates with one set of thread segments and a right-hand lead screw nut that cooperates with the other set of thread segments. The threads on the same side of the two sets of bidirectional lead screws 221 have the same direction of rotation. The setting of the bidirectional lead screws 221 will restrict the rotation of the lead screw nuts around the axis of the corresponding bidirectional lead screw 221.

[0059] In order to effectively install the bidirectional lead screw 221, a lead screw drive seat that rotates with the bidirectional lead screw 221 is provided on the base plate 1. There are two sets of lead screw drive seats for each set of bidirectional lead screw 221, and they are located at both ends of the bidirectional lead screw 221.

[0060] In some possible implementations, the drive device 223 includes two sets of drive shafts 2231 coaxially arranged along the X-axis, and drive members 2232 connected to the two sets of drive shafts 2231 respectively and located between the two sets of drive shafts 2231. The two sets of drive shafts 2231 share one set of drive members 2232. The two sets of drive shafts 2231 are respectively provided with a transmission structure 224 that is in transmission cooperation with the bidirectional lead screw 221 at one end away from each other.

[0061] In some possible implementations, the drive unit 2232 includes a drive motor 22321, a primary spur gear 22322 mounted on and coaxially connected to the output shaft of the drive motor 22321, and a secondary spur gear 22323 located between two sets of transmission shafts 2231 and connected to the two sets of transmission shafts 2231 respectively via a coupling 22324; the primary spur gear 22322 meshes with the secondary spur gear 22323.

[0062] Specifically, the drive motor 22321 starts and drives the slave spur gear 22323 to rotate through the main spur gear 22322. Under the drive of the coupling 22324, the transmission shaft 2231 rotates around its axis. Since the two sets of transmission shafts 2231 are connected to the same side end of the double-acting screw 221 through the transmission structure 224, the two sets of double-acting screws 221 rotate around their axes. When the two sets of double-acting screws 221 rotate synchronously, the rotation direction is the same.

[0063] When the drive motor 22321 receives a rotation command, it drives the main spur gear 22322 to rotate, thereby driving the slave spur gear 22323 to rotate. The power is distributed to the two sets of transmission shafts 2231 through the two couplings 22324, and then transmitted to the two sets of symmetrically arranged double-acting lead screws 221 through the transmission structure 224. The double-acting lead screws 221 rotate, thereby driving the two sets of lead screw nuts 222 on each set of double-acting lead screws 221 to move, and then driving the two centering beams 21 to move in opposite directions at the same speed. The centering beams 21 act on the vertical rod 101 of the UAV 100 to achieve the centering of the UAV 100 in the Y-axis direction.

[0064] In some possible implementations, in order to effectively realize the transmission connection between the two sets of transmission shafts 2231 and the two sets of bidirectional lead screws 221, the transmission structure 224 includes a bevel gear 2241 coaxially connected to one end of the drive device 223 connected to the transmission shaft 2231, and a bevel gear 2242 mounted on the bidirectional lead screw 221 and meshing with the bevel gear 2241.

[0065] In some possible implementations, in order to effectively center and lock the UAV 100 in the X-axis direction using the locking component 31, the locking component 31 includes a locking slider 311 that is connected to the centering drive component 32 and slides along the X-axis direction, and a locking claw 312 mounted on the locking slider 311. The locking slider 311 is located at the bottom of the base plate 1 and slides with the base plate 1. A groove 11 is provided on the base plate 1 along the X-axis direction to cooperate with the locking claw 312. The locking claw 312 is located in the groove 11 and its end away from the locking slider 311 passes through the base plate 1. One end of the locking claw 312 passes through the groove 11 and is connected to the locking slider 311. Under the drive of the centering drive component 32, the two sets of locking sliders 311 move closer to each other along the X-axis direction, thereby driving the locking claw 312 to move closer to each other to achieve centering and final locking of the UAV 100 in the X-axis direction.

[0066] The locking claws 312 in the two sets of locking components 31 are provided with arc-shaped grooves 3121 that cooperate with the crossbar 102 on one side close to each other.

[0067] When centering and locking the drone 100 in the X-axis direction, the centering drive component 32 controls the two sets of locking sliders 311 to move closer to each other in the Y-axis direction, thereby driving the locking claws 312 to move closer to each other in the X-axis direction. This allows the two sets of locking claws 312 to contact and abut against the outer side of the crossbar 102 on the side that is close to each other, thus achieving centering in the X-axis direction. The arc groove 3121 increases the contact area between the locking claws 312 and the crossbar 102. After centering, the crossbar 102 will be locked within the arc groove 3121. The plug assembly 33 is fixedly connected to the locking claws 312. When the locking claws 312 move in the X-axis direction, they drive the plug assembly 33 to move in the X-axis direction to achieve charging.

[0068] Specifically, there are two sets of locking claws 312 on each set of locking sliders 311, which are symmetrically arranged along the X-axis. There are two sets of sliding grooves 11, which are used in conjunction with the two sets of locking claws 312. When there are two sets of locking claws 312 on the locking slider, the plug assembly 33 will be located between the two sets of locking claws 312. At this time, there will also be two sets of sliding grooves 11 in each set of locking assembly 31.

[0069] In some possible implementations, in order to effectively drive the two sets of locking sliders 311 to move closer or further apart along the X-axis direction via the centering drive assembly 2 32, the centering drive assembly 2 32 is installed at the bottom of the base plate 1 and includes a lead screw 2 321 coaxially arranged along the X-axis direction and corresponding one-to-one with the two sets of locking sliders 311, a centering reversing assembly 322 disposed between the two sets of lead screws 2 321 and drivingly engaged with the two sets of lead screws 2 321, a drive motor 2 323 drivingly connected to the centering reversing assembly 322, and a linear guide rail 324 slidingly engaged with the locking sliders 311 along the X-axis direction; the lead screw 2 321 is a ball screw; there are two sets of linear guide rails 324;

[0070] The base plate 1 of the second lead screw 321 is rotatably engaged, and the locking slider 311 is fitted on the outside of the second lead screw 321 and screwed into the second lead screw 321.

[0071] During centering in the X-axis direction, drive motor 2 323 starts, driving two sets of lead screws 2 321 to rotate around their axes in opposite directions via centering reversing assembly 322; locking slider 311 is fitted on the outside of lead screw 2 321 and screwed to lead screw 2 321 via lead screw nut 2, and under the constraint of linear guide rail 324, each set of locking slider 311 can only move in the X-axis direction; thereby driving the locking claws 312 on the two sets of locking assemblies 31 to move closer to each other;

[0072] Furthermore, the output shaft of the second drive motor 323 is arranged along the Y-axis and is connected to the centering reversing assembly 322 via the second coupling 325; the centering reversing assembly 322 includes a centering reversing device 3221 connected to the second coupling 325; the centering reversing device 3221 includes two sets of output shafts A3222 coaxially arranged and connected to the two sets of lead screws 321 respectively; the two sets of output shafts A3222 are respectively connected to the lead screws 321 via the third coupling 326.

[0073] Under the control of drive motor 323, the two sets of output shafts A3222 rotate in opposite directions around their axes; thus, through coupling 326, they drive the two sets of lead screws 321 to rotate in opposite directions.

[0074] The drive motor 323 converts the driving force into two equal and opposite torques through the centering commutator 3221, which in turn drive the two lead screws 321 to rotate in opposite directions at the same speed, thereby causing the two locking sliders 311 to perform linear motion in opposite directions at the same speed. The locking claw 312 acts on the crossbar 102 of the UAV 100 to center and lock the UAV 100 in the X-axis direction.

[0075] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
