In order to make the unmanned aerial vehicle reach the working range for use, auxiliary equipment is often used to carry the unmanned aerial vehicle to the working range for operation of the unmanned aerial vehicle. However, in the prior art, the auxiliary equipment of the unmanned aerial vehicle is mostly a simple moving seat or platform or a combination structure of the two, which has a simple structure and single functionality and can only play a simple carrying role. After one operation of the unmanned aerial vehicle, due to the influence of factors such as wind pressure, the unmanned aerial vehicle cannot be accurately landed at the accurate position, and generally deviates by more than a few centimeters, so that manual adjustment of the assembly position of the unmanned aerial vehicle is required to ensure the accuracy and stability of the assembly position, which is inconvenient. In addition, before operation, the existing unmanned aerial vehicle needs to be temporarily configured with liquid for spraying by manual operation and added to the storage bin of the unmanned aerial vehicle, which affects the operation time and is inconvenient. After the operation of the unmanned aerial vehicle is completed, if there is residual liquid in the storage bin, the structure stability of the unmanned aerial vehicle will be affected by the impact of the shaking of the residual liquid during subsequent movement, which may cause damage to the equipment and is inconvenient.

[0027] (III) Beneficial Effects

[0028] One of the above technical solutions has the following advantages or beneficial effects:

[0029] 1. By providing a detachable support platform on the mobile base, the drone is mounted on the support platform. The support platform can be moved and used at high and low positions through the lifting support frame assembled by the sliding mechanism, and can be used for mobile support and fixed support through the lifting wheel set. The limiting mechanism at the top of the support platform, combined with the transmitter and the receiver mounted on the drone, allows the drone to automatically fall back to a certain height at the top of the support platform through the existing positioning system when it falls back. Then, it is accurately positioned by the transmitter and receiver, and actively docked with the hovering drone through the limiting device with lifting function. After the drone stops flying, the limiting device drives the docked drone to land on the support platform. This can ensure the stability of the drone's position on the support platform, realize the direct and accurate positioning and assembly of the drone when it falls back, and avoid the inconvenience of the drone's accuracy being affected by wind pressure and other factors when it falls, which requires manual adjustment of the drone's position for accurate and stable assembly.

[0030] 2. When the carrier platform is moved to the moving seat for assembly, the positioning mechanism on the moving seat can be connected to the positioning joint of the carrier platform through the docking plate. Combined with the detection of the first sensor of the positioning structure, it can be determined whether the carrier platform is in the precise assembly position. Then, the carrier platform is pulled by the electric hoist driving the traction rope, so that the carrier platform can be moved precisely to the positioning mechanism through traction, ensuring the assembly accuracy of the carrier platform and also ensuring the stability of the carrier platform assembly, preventing the carrier platform from tipping over due to instability when it is removed from the moving seat.

[0031] 3. The support platform is also equipped with a storage bin and an automatic material control device. Combined with the feeding cover of the drone and the precise positioning and assembly of the drone and the support base, the automatic material control device can automatically add material to the drone's bin before use and automatically discharge material after use when the drone is assembled on the mobile base. This achieves material control of the drone's bin, eliminating the inconvenience of temporary material preparation and addition before the drone is used, and preventing structural damage caused by residual material in the bin impacting the drone as it moves with the mobile base.

Detailed Implementation

[0047] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0048] Example 1:

[0049] This invention provides an intelligent carrier system that facilitates the movement of unmanned aerial vehicles (UAVs): its structure includes a mobile base 1, a carrier platform 2, and an UAV 4;

[0050] It also includes a positioning mechanism 3, a storage box 5, an automatic material control device 6, a feeding cover 7, and a receiver 8. The positioning mechanism 3 and the storage box 5 are both fixed on the movable seat 1. The movable seat 1 is also equipped with a support platform 2. One end of the support platform 2 is connected to the positioning mechanism 3. The automatic material control device 6 is assembled on the top of the storage box 5.

[0051] The support platform 2 includes a limiting mechanism 201, a lifting support frame 202, a sliding mechanism 203, a main platform 204, a lifting wheel assembly 205, a positioning connector 206, a first battery 207, a control module 208, and a transmitter 209. The main platform 204 contains the first battery 207 and the control module 208. The bottom of the main platform 204 is equipped with the lifting wheel assembly 206. The bottom of the main platform 204 is also equipped with the lifting support frame 202 via the sliding mechanism 203. A positioning connector 206 is fixed on one side of the main platform 204. The top of the main platform 204 is equipped with a limiting mechanism 201 with lifting function. The limiting mechanism 201 is used for active connection and limiting of the UAV 4. The top of the main platform 204 is equipped with two or more transmitters 209. The UAV 4 is equipped with a receiver 8 directly above the transmitter 209. The hopper of the UAV 4 is equipped with a feeding cover 7 used in combination with the automatic material control device 6.

[0052] The positioning mechanism 3 includes a body 301, a traction rope 302, a docking plate 303, an electric hoist 304, and a first sensor 305. There are two or more first sensors 305 located on the side of the body 301 adjacent to the support platform 2. The first sensor 305 is used to determine whether the position of the support platform 2 is correct. The electric hoist 304 is assembled inside the body 301 and connected to one end of the traction rope 302. The other end of the traction rope 302 is fixedly connected to the docking plate 303. The docking plate 303 is spliced ​​with the positioning connector 206. The automatic material control device 6 is used to add or discharge material to the drone 4 after the position of the support platform 2 is determined to be correct, in combination with the feeding cover 7.

[0053] This also includes a controller (not shown in the figure).

[0054] Before using the drone 4, the controller can control the automatic material control device 6 to move to dock with the feeding cover 7 of the drone 4. Then, the automatic material control device 6 automatically fills the drone's hopper with material. After the material is added, the automatic material control device 6 automatically resets and enters standby mode. Then, the support platform 2 can lower the lifting wheel assembly 205 until it is in the support state of the lifting wheel assembly 205. Then, the support platform 2 can be moved to the edge of the moving seat 1. Then, the lifting support frame 202 is slid laterally out of the moving seat 1 through the sliding mechanism 203. Then, the lifting support frame 202 is driven to unfold until the bottom is supported by the bottom surface. Then, the main platform 204 can slide above the lifting support frame 202. During this process, the traction rope 302 of the positioning mechanism 3 can be controlled and released by the electric hoist 304, so that the main platform 204 is under the traction rope throughout the process. The appropriate traction force of 302 prevents the main platform 204 from tipping over due to the slippage of the lifting support frame 202, ensuring the smooth movement of the main platform 204 throughout the process. Then, when the main platform 204 has completely moved above the lifting support frame 202, the main platform 204 can be released from traction by disconnecting the splicing of the positioning joint 206 and the docking plate 303. Then, the lifting support frame 202 can be controlled to retract until the lifting wheel assembly 205 supports the ground. At this time, the carrying platform 2 can be moved to a suitable position to release the connection between the limiting mechanism 201 and the drone 4 to launch the drone 4. During launch, the lifting support frame 202 can also be raised as needed to prevent debris at low levels from interfering with the rotor of the drone 4. The liftable limiting mechanism 201 allows the system to be launched from both ends, increasing the launch height.

[0055] When the drone 4 returns to its starting position after completing its work, it can use the existing positioning system to return to the approximate location on the top of the main platform 204. Then, it can use the transmitter 209 of the main platform 204 and the receiver 8 of the drone 4 to match the signal for precise positioning. The combination of two or more transmitters 209 and receivers 8 can enable the drone 4 to achieve both position positioning and assembly direction positioning. After the position and direction of the drone 4 are identified, the drone 4 can be in a hovering state. Then, the liftable limiting mechanism 201 can be raised to dock with the drone 4. After docking, the drone 4 stops rotating its rotor and is placed on the limiting mechanism 201. Then, the limiting mechanism 201 returns to the main platform 204, achieving precise parking of the drone 4 in the position and direction of the main platform 204.

[0056] After the drone 4 is placed on the support platform 2, the support platform 2 can lift the drone 4 back to the edge of the moving seat 1 and then use the splicing positioning joint 206 and the docking plate 303 to stabilize the assembly of the support platform 2. Then the lifting support frame 202 can be retracted, and the support platform 2 can be moved to the fixed position on the moving seat 1 by the traction rope 302. After the support platform 2 moves to the fixed position, two or more first sensors 305 can detect whether the support platform 2 has moved into place. If the first sensor 305 is a pressure sensor or a limit switch, if two or more sensors are not triggered by pressure, it can be considered that the support platform 2 has not yet moved to the precise assembly position, thus ensuring the assembly accuracy of the support platform 2.

[0057] Under the premise that the carrier platform 2 and the drone 4 are precisely assembled, the system can again control the automatic material control device 6 to dock with the feeding cover 7 of the drone 4's storage bin, and discharge the remaining material in the drone 4's storage bin back to the storage box 5. This can avoid structural damage caused by the impact of the remaining material in the storage bin during the movement of the drone with the mobile seat, and realize a multi-functional intelligent carrier system that can accurately position and assemble, automatically add and discharge materials, and ensure the safe movement of the drone 4.

[0058] Example 2:

[0059] Compared to Embodiment 1, the support platform 2 in this embodiment further includes an electrically controlled pin 210, which is fixed to the side of the main platform 204. The movable seat 1 is provided with a slot for the electrically controlled pin 210 to be inserted when the position of the support platform 2 is correctly determined. The electrically controlled telescopic structure 212 is used to electrically control the lifting support frame 202 to slide at the sliding mechanism 203. After the support platform 2 is moved to a suitable position by the positioning mechanism 3, the controller can control the electrically controlled pin 210 to be inserted into the slot of the movable seat 1 for positioning, so as to prevent the support platform 2 from causing the positioning mechanism 3 to be damaged due to excessive force when the movable seat 1 moves subsequently. The rest of the structure and effect remain unchanged.

[0060] Example 3:

[0061] Compared to the previous embodiments, the limiting mechanism 201 in this embodiment includes a first electrically controlled telescopic rod 20101, a first storage groove 20102, a sliding block 20103, a limiting block 20104, a limiting groove 20105, a limiting assembly block 20107, a second electrically controlled telescopic rod 20109, and a main unit 20110. The limiting assembly block 20107 has sliding blocks 20103 movably sleeved on both sides. One end of the second electrically controlled telescopic rod 20109 is located within the limiting assembly block 20107, and the other end is fixedly connected to the sliding block 20103. The main unit 20110 is located within the limiting assembly block 20107 and is used to control the extension and retraction of the second electrically controlled telescopic rod 20109. The top of the sliding block 20103 is fixed with a limiting block 20104. The limiting block 20104 is provided with a limiting groove 20105, which penetrates the upper and lower ends of the limiting block 20104 and the middle side of the adjacent limiting assembly block 20107. The side end of the limiting groove 20105 is an inclined surface that tapers away from the middle side of the limiting assembly block 20107, so as to guide the drone 4 to the correct position when the limiting groove 20105 is connected to the drone 4. The side of the limiting groove 20105 away from the middle side of the limiting assembly block 20107 is an inclined surface that gradually expands from top to bottom. The first storage groove 20102 is provided on the top of the main platform 204. One end of the first electrically controlled telescopic rod 20101 is fixedly connected to the main platform 204, and the other end of the first electrically controlled telescopic rod 20101 passes through the first storage groove 20102 and is fixedly connected to the limiting assembly block 20107.

[0062] When the UAV 4 lands and hovers, the first electrically controlled telescopic rod 20101 raises the limiting assembly block 20107 to a suitable height. Simultaneously, the main unit 20110 controls the second electrically controlled telescopic rod 20109 to move the sliding blocks 20103 on both sides of the limiting assembly block 20107 away from the limiting assembly block 20107, thus causing the limiting blocks 20104 on the sliding blocks 20103 to move away from each other, i.e., to be in an open state. Then, the limiting assembly block 20107 connects to the UAV 4 at the connection point, such as... Figure 1As shown, the connection point is generally the footrest of the drone 4. Then, the main unit 20110 controls the second electrically controlled telescopic rod 20109 to move the sliding block 20103 toward the limiting assembly block 20107, so that the limiting blocks 20104 move closer to each other, that is, in the retracted state, until the limiting groove 20105 of the limiting block 20104 moves away from the middle of the limiting assembly block 20107 and fits against the footrest of the drone 4. At this time, because the limiting groove 20105 moves away from the limiting assembly block 20107, The middle side is a slope that gradually widens from top to bottom, so that the position of the drone 4's landing gear will be restricted by the slope of the limiting groove 20105, so that the drone 4 can be accurately positioned and assembled on the limiting assembly block 20107. At this time, the drone 4 can stop the rotation of the rotor and complete the landing. Through active docking, the drone 4 can avoid the impact of wind pressure and other factors on the accurate landing. Finally, the first electronically controlled telescopic rod 20101 can be lowered down the limiting assembly block 20107 and fall back to the top of the main body 204 for stable assembly.

[0063] When the drone is to be launched, the main unit 20110 can directly control the second electronically controlled telescopic rod 20109 to release the drone 4 from its restricted position, or it can raise the limit assembly block 20107 and then drive the second electronically controlled telescopic rod 20109 to release the drone 4 from its restricted position, thus launching the drone 4.

[0064] With the retractable limiting block 20104 structure and the special limiting groove 20105 structure, the drone 4 can be guided to a precise position by the side slope of the limiting groove 20105 during the retraction of the limiting block 20104. The end slope structure of the limiting groove 20105 can directly limit and lock the drone 4 after the limiting block 20104 is retracted, which is convenient and quick. The rest of the structure and effect are the same as those in the aforementioned embodiment.

The assembly ring 604 is sleeved and fixed on the docking body 611. The connecting joint 615 is used to dock with the feeding cover 7. The connecting joint 615 is fixedly connected to one end of the third electrically controlled telescopic rod 610. The other end of the third electrically controlled telescopic rod 610 is assembled inside the docking body 611. The first power source 602 is used to drive the third electrically controlled telescopic rod 610 to rise and fall. The side end face of the swing assembly body 609 is provided with... The swing groove 608 is provided, and the connecting ball 612 is disposed in the swing groove 608. The second power source 607 is used to drive the connecting ball 612 to drive the connecting pipe 606 to swing. One end of the telescopic pipe 614 is connected to the docking joint 615 and communicates with the bottom of the docking joint 615. The other end of the telescopic pipe 614 is disposed in the docking body 611 and communicates with one end of the suction pipe 605. The assembly ring 604 passes through the swing groove 608 through the connecting pipe 606 and is fixedly connected to the connecting ball 612. The connecting ball 612 is also connected to the first pump 603 through the rotary joint 613. The other end of the suction pipe 605 passes through the connecting ball 612 and communicates with the rotary joint 613. The first pump 603 is also connected to the storage box 5. The pad 601 is fixed to the top of the storage box 5 and is used for placement and support when the docking body 611 is idle.

[0072] Furthermore, the feeding cover 7 includes a connecting pipe 701, a first cover 702, a second cover 703, a third cover 704, a guide groove 705, a shaft 706, and a torsion spring 707. The first cover 702 is used to connect to the hopper opening of the UAV 4. The second cover 703 is fixed to the top of the first cover 702. The guide groove 705 is provided on the top of the second cover 703. The connecting pipe 701 is fixed to the bottom of the first cover 702. The connecting pipe 701 communicates with the guide groove 705. The third cover 704 is assembled on the top of the second cover 703 through the shaft 706. The torsion spring 707 is assembled between the shaft 706 and the third cover 704. The connecting joint 615 is used to laterally press the third cover 704 out of the range of the guide groove 705.

[0073] In use, the second power source 607 drives the connecting ball 612 to rotate. Due to the rotary joint 613, the rotation of the connecting ball 612 can maintain communication with the first pump 603. When the connecting ball 612 rotates, it will cause the connecting pipe 606 to swing within the swing groove 608. By setting a pre-set distance, excessive swinging of the connecting pipe 606 can be prevented. When the connecting pipe 606 swings, the assembly ring 604 on the side of the connecting pipe 606 away from the connecting ball 612 will cause the docking body 611 to swing accordingly. When the docking body 611 is out of the range of the pad 601, the system can be connected by the first power source. 602 controls the third electrically controlled telescopic rod 610 to drive the connector 615 to descend a suitable distance, so that the docking body 611 swings a certain distance. Then, the connector 615 will laterally press the third cover 704 out of the guide trough 705. At this time, the first pump 603 can draw the material in the storage box 5 through the suction pipe 605 → telescopic pipe 614 → guide trough 705 → connecting pipe 701 into the hopper of the drone 4, realizing automatic feeding of the drone 4. When the remaining material is drawn out, it can be drawn out in the opposite direction by the first pump 603, which is convenient and fast. The rest of the structure and effect are unchanged compared with the above embodiment.
