Description

TECHNICAL FIELD

[0001] The application relates to unmanned aerial vehicle charging technology, in particular to a movable unmanned aerial vehicle taking-off and landing wireless charging platform and a use method thereof. BACKGROUND

[0002] With the rapid development of science and technology, unmanned aerial vehicles have been widely used in many fields, covering aerial surveying and mapping, agricultural plant protection, logistics distribution, environmental monitoring, emergency rescue and other industries. In the field of aerial surveying and mapping, unmanned aerial vehicles can quickly obtain high-resolution geographic information data to provide accurate basis for city planning and land surveying. In the field of agricultural plant protection, unmanned aerial vehicles can realize efficient and accurate pesticide spraying and crop monitoring, greatly improving the efficiency of agricultural production. In the field of logistics distribution, unmanned aerial vehicles can break through the limitations of traditional transportation and realize rapid distribution in remote areas or emergency situations. In the field of environmental monitoring, unmanned aerial vehicles can carry various sensors to monitor air quality, water quality and soil in real time. In the field of emergency rescue, unmanned aerial vehicles can quickly reach the disaster site to assess the disaster situation and deliver materials.

[0003] During the charging of the unmanned aerial vehicle, there are some problems to be solved. Due to the interference of the external environment, such as strong wind, electromagnetic interference, or the vibration generated by the unmanned aerial vehicle itself during charging, the unmanned aerial vehicle is prone to displacement during charging. This displacement not only causes the charging to be interrupted, affecting the normal use of the unmanned aerial vehicle, but also may cause damage to the charging equipment, increasing the use cost and maintenance difficulty. Therefore, a movable unmanned aerial vehicle taking-off and landing wireless charging platform and a use method thereof are provided. SUMMARY

[0004] The purpose of the present application is to provide a movable unmanned aerial vehicle taking-off and landing wireless charging platform and a use method thereof to solve the problem that in the prior art, due to the interference of the external environment, such as strong wind, electromagnetic interference, or the vibration generated by the unmanned aerial vehicle itself during charging, the unmanned aerial vehicle is prone to displacement during charging. This displacement not only causes the charging to be interrupted, affecting the normal use of the unmanned aerial vehicle, but also may cause damage to the charging equipment, increasing the use cost and maintenance difficulty.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: a movable unmanned aerial vehicle taking-off and landing wireless charging platform, comprising a support chassis, a moving wheel, a support frame, a support plate, a plurality of charging batteries and a lighting lamp, further comprising:

[0010] Further, the first lifting charging mechanism comprises a support table and a first bearing table arranged on the support plate, a U-shaped frame fixedly arranged on the support table, a first rotary drive arranged on the U-shaped frame, a plurality of fixed plates arranged around the top of the support table, a first crank plate rotatably connected to the U-shaped frame through a plurality of first rotating shafts, a second crank plate rotatably connected to the outer wall of the first bearing table through a plurality of second rotating shafts, the first crank plate and the second crank plate being rotatably connected through a third rotating shaft, a first charging head arranged on the top of the U-shaped frame, a first charging coil arranged on the first bearing table, and the first charging head and the first charging coil being arranged in corresponding connection.

[0011] Further, the second lifting charging mechanism comprises a plurality of support frames and a lifting table arranged on the support plate, a mounting plate arranged on each side of the top of each support frame, a fourth crank plate rotatably connected to the two mounting plates through a first rotating rod, a third crank plate rotatably connected to each side of the lifting table through a second rotating rod, a third rotary drive arranged on one side of one of the mounting plates, a second bearing table arranged on each side of the top of the support frame, a second charging coil arranged on the second bearing table, a second charging head arranged on the top of the lifting table, and the first bearing table being arranged between the second bearing table and the support frame.

[0012] Furthermore, the shading mechanism includes multiple support rods installed on both sides of the support frame. A winding box and a mounting box are fixedly connected between two support rods respectively. A second rotary drive is fixedly connected to one side of the outer wall of the mounting box. A rotating rod is fixedly connected to the output end of the second rotary drive. The end of the rotating rod away from the second rotary drive extends rotatably into the interior of the mounting box. Traction ropes are wound around both sides of the outer wall of the rotating rod. A winding shaft is rotatably connected inside the winding box. Both ends of the winding shaft extend rotatably to the outside of the winding box. Fixed discs are fixedly connected to both ends of the winding shaft. Torsion springs are connected to the inner side of the fixed discs. A sunshade tarpaulin is wound around the outer wall of the winding shaft inside the winding box.

[0013] Furthermore, the mounting bracket has a limiting groove inside, below the sliding rack and the clamping block, and a limiting slider is provided at the bottom of the sliding rack and the clamping block. The limiting slider and the limiting groove are slidably arranged accordingly. A square through slot is provided on the second support platform, and the top of the clamping rod extends to the top of the second support platform through the square through slot. The second charging head and the second charging coil are connected accordingly. One side of the clamping block is connected to the sliding rack.

[0014] Furthermore, the end of the traction rope away from the rotating rod is connected to the sunshade fabric, and a plurality of sliding holes are provided on one side of the mounting box, through which the end of the traction rope away from the rotating rod extends slidably to the outside of the mounting box.

[0015] Furthermore, the end of the torsion spring away from the fixed plate is connected to the outer wall of the winding box, and the torsion spring is sleeved on the outer wall of the winding shaft. A sliding groove is provided on one side of the winding box, and the end of the awning cloth away from the winding shaft extends slidably to the outside of the winding shaft through the sliding groove.

[0016] A method for using a mobile wireless charging platform for drone take-off and landing includes the following steps:

[0017] Step 1: When it is necessary to charge the medium-sized drone, start the first rotary drive component. Its output end drives the first rotating shaft on the U-shaped frame to rotate, so that the first crank plate and the second crank plate are linked together, thereby driving the first support platform to move up and down reciprocally, so that the first charging head contacts the first charging coil. At this time, the medium-sized drone placed on the first support platform will start charging.

[0018] Step 2: Activate the third rotary drive component to drive the relevant crank plate to rotate, causing the lifting platform to move up and down. When the lifting platform rises and the second charging head contacts the second charging coil, it charges the small drone placed at the corresponding position on the second support platform.

[0019] Step 3: When the small drone is placed on the second support platform, activate the two hydraulic cylinders. The hydraulic cylinders push the clamping blocks to move in opposite directions, thereby driving the clamping rod to clamp the small drone.

[0020] Step 4: When it is necessary to provide shade and protection above the first and second support platforms, start the second rotary drive unit in the forward direction, which will drive the rotating rod to rotate. This will allow the traction rope to pull the awning cloth out from inside the winding box through the sliding groove, thus shielding the charging mechanism. When it is not necessary to shield, start the second rotary drive unit in the reverse direction, release the traction rope, and under the elastic force of the torsion spring, the winding shaft will rotate, rewinding the awning cloth back into the winding box.

[0021] Compared with the prior art, the present invention provides a mobile wireless charging platform for drone take-off and landing and its usage method. Through the action of the clamping mechanism, the hydraulic cylinders on both sides of the outer wall of the mounting frame drive the clamping blocks to move towards each other, thereby driving the clamping rod to clamp the small drone placed on the second support platform. At the same time, the sliding rack inside the mounting frame meshes with the rotating gear fixedly connected by the rotating shaft, which slows down the movement of the clamping blocks and reduces the clamping force to avoid damage to the drone. This design ensures the stability of the small drone during the charging process, prevents charging interruption or equipment damage due to shaking or displacement, and improves the reliability and safety of charging.

[0022] In the initial state, the awning cloth is wrapped and rolled up on the outer wall of the take-up shaft and located inside the take-up box, thus being effectively protected. When needed, the second rotary drive is activated by rotating the forward rotation, which drives the rotating rod to rotate. The traction rope pulls the awning cloth out from inside the take-up box and slides it out through the sliding groove to shield the top of the first and second support platforms. This design can effectively cope with severe weather such as rain, snow, and scorching sun, providing protection for charging equipment and drones, extending the service life of the equipment, and ensuring that the charging process can proceed smoothly in various environments.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As attachedFigure 1 To be continued Figure 8 As shown:

[0036] Example 1:

[0037] This invention provides a mobile wireless charging platform for drone take-off and landing and its usage method, including a supporting base 1, wheels 2, a supporting frame 3, a supporting plate 4, multiple sets of rechargeable batteries 5, and a lighting lamp 10, and also includes:

[0038] The first lifting and charging mechanism is used to charge a medium-sized drone. The first lifting and charging mechanism is located on the support frame 3. The first lifting and charging mechanism includes a support platform 7 and a first carrier platform 707 installed on the support plate 4. A U-shaped frame 701 is fixedly installed on the support platform 7. A first rotary drive component 702 is installed on the U-shaped frame 701. Multiple fixing plates 703 are installed around the top of the support platform 7. The fixing plates 703 and the U-shaped frame 701 are rotatably connected to a first crank plate 704 through multiple first rotating shafts. The outer wall of the first carrier platform 707 is rotatably connected to a second crank plate 705 through multiple second rotating shafts. The first crank plate 704 and the second crank plate 705 are rotatably connected through a third rotating shaft. A first charging head 706 is provided on the top of the U-shaped frame 701. A first charging coil 708 is provided on the first carrier platform 707. The first charging head 706 and the first charging coil 708 are correspondingly connected.

[0039] Working principle: When a medium-sized drone needs to be charged, the first rotary drive 702 is activated, and its output end drives the first rotating shaft on the U-shaped frame 701 to rotate. Due to the rotation of multiple first rotating shafts, multiple second rotating shafts, and multiple third rotating shafts, the first crank plate 704 and the second crank plate 705 are linked, which in turn drives the first support platform 707 to move up and down reciprocally. When the first support platform 707 rises to a suitable position, the first charging head 706 contacts the first charging coil 708, and charging of the medium-sized drone placed on the first support platform 707 begins. When charging is complete or charging needs to be interrupted, the first rotary drive 702 is activated again, causing the first support platform 707 to descend, and the first charging head 706 disengages from the first charging coil 708, thus cutting off the power.

[0040] Through the above technical solution, the first lifting and charging mechanism located on the support frame 3, through the coordinated operation of components such as the support platform 7, U-shaped frame 701, first rotating drive component 702, fixed plate 703, first crank plate 704, and second crank plate 705, utilizes the rotational characteristics of multiple first, second, and third rotating shafts to realize the up-and-down reciprocating motion of the first support platform 707. When the first support platform 707 rises, the first charging head 706 contacts the first charging coil 708 to charge the medium-sized drone placed on the first support platform 707; when it descends, the connection is disconnected to cut off the power. This precise contact and separation control ensures the safety and stability of the charging process, avoids overcharging problems that may be caused by continuous connection, and facilitates the take-off and landing operations of the drone.

[0041] Example 2:

[0042] This embodiment is basically the same as the previous embodiment, except that multiple sets of second lifting and charging mechanisms are used for charging multiple small drones. The second lifting and charging mechanisms are installed on the support plate 4. The second lifting and charging mechanisms include multiple support frames 9 and lifting platforms 905 installed on the support plate 4. Mounting plates 901 are installed on the top two sides of the support frame 9. The two mounting plates 901 are rotatably connected to the fourth crank plate 906 through the first rotating rod. The two sides of the lifting platform 905 are rotatably connected to the third crank plate 904 through the second rotating rod. A third rotary drive component 902 is installed on one side of one of the mounting plates 901. The top two sides of the support frame 3 are equipped with second bearing platforms 903. The second bearing platform 903 is provided with a second charging coil 907. The top of the lifting platform 905 is provided with a second charging head 908. The first bearing platform 707 is located between the second bearing platform 903 and the support frame 3.

[0043] Working principle: The working process is the same as the first lifting and charging mechanism. The third rotary drive 902 is activated, which drives the relevant crank plate to rotate, causing the lifting platform 905 to move up and down. When the lifting platform 905 rises and the second charging head 908 contacts the second charging coil 907, the small drone placed on the corresponding position of the second support platform 903 is charged. After charging is completed, the lifting platform 905 is lowered, the second charging head 908 is disengaged from the second charging coil 907, and charging stops. At the same time, the first support platform 707 is located between the second support platform 903 and the support frame 3, which can limit the medium-sized drone placed on the first support platform 707.

[0044] Through the above technical solution, multiple sets of second lifting and charging mechanisms installed on the support plate 4, taking one set as an example, through the cooperation of components such as the support frame 9, mounting plate 901, fourth crank plate 906, third crank plate 904, and third rotary drive component 902, as well as the second charging coil 907 set on the second bearing platform 903 and the second charging head 908 set on the top of the lifting platform 905, the charging function of multiple small drones is realized. Its working principle is similar to that of the first lifting and charging mechanism, but it has been optimized for the characteristics of small drones, and can meet the charging needs of multiple small drones at the same time, improving charging efficiency. It is especially suitable for scenarios that require batch charging, such as the charging stage after drone formation operation.

[0045] Example 3:

[0046] This embodiment is basically the same as the previous embodiment, except that multiple clamping mechanisms are used to clamp and charge the small drones on multiple sets of second lifting and charging mechanisms. The multiple clamping mechanisms are located on the support plate 4. The clamping mechanism includes a mounting frame 6 installed on the support plate 4. Hydraulic cylinders 601 are installed on both sides of the outer wall of the mounting frame 6. One end of each hydraulic cylinder 601 extends into the interior of the mounting frame 6. A clamping block 605 is installed at the end of the hydraulic cylinder 601 extending into the mounting frame 6. Sliding racks 602 are slidably connected to both sides of the interior of the mounting frame 6. A rotating gear 604 is fixedly connected between the two sliding racks 602 inside the mounting frame 6 via a rotating shaft 603. The rotating shaft 603 and the mounting frame 6 are rotatably connected. A clamping rod 606 is fixedly connected to the top of each clamping block 605.

[0047] The present invention is further described in detail as follows: the interior of the mounting bracket 6 is provided with limiting grooves below the sliding rack 602 and the clamping block 605; the bottom of the sliding rack 602 and the clamping block 605 is provided with limiting sliders; the limiting sliders and the limiting grooves are correspondingly slidably arranged; the second support platform 903 is provided with a square through groove; the top of the clamping rod 606 extends to the top of the second support platform 903 through the square through groove; the second charging head 908 and the second charging coil 907 are correspondingly connected; one side of the clamping block 605 is connected to the sliding rack 602.

[0048] Working principle: When the small drone is placed on the second support platform 903, two hydraulic cylinders 601 are activated. The hydraulic cylinders 601 push the clamping blocks 605 to move towards each other. Since the clamping blocks 605 are connected to the sliding rack 602, and the sliding rack 602 is meshed with the rotating gear 604, during the movement of the clamping blocks 605 towards each other, the sliding rack 602 drives the rotating gear 604 to rotate, which slows down the movement speed of the clamping blocks 605. This reduces the force with which the clamping blocks 605 drive the clamping rod 606 to clamp the small drone, thus avoiding damage to the drone. The distance between the two clamping blocks 605 decreases, which drives the clamping rod 606 to clamp the small drone stably, ensuring that the drone's position is fixed during charging.

[0049] With the above technical solution, multiple clamping mechanisms located on the support plate 4, taking one of them as an example, drive the clamping blocks 605 to move in opposite directions via hydraulic cylinders 601 on both sides of the outer wall of the mounting frame 6, thereby causing the clamping rod 606 to clamp the small drone placed on the second support platform 903. At the same time, the sliding rack 602 slidably connected inside the mounting frame 6 meshes with the rotating gear 604 fixedly connected via the rotating shaft 603, which slows down the movement of the clamping blocks 605, reduces the clamping force, and avoids damage to the drone. This design ensures the stability of the small drone during the charging process, prevents charging interruption or equipment damage due to shaking or displacement, and improves the reliability and safety of charging.

[0050] Example 4:

[0051] This embodiment is basically the same as the previous embodiment, except that a shielding mechanism is used to shield and protect the top of the first and second lifting charging mechanisms. The shielding mechanism is located above the support frame 3 and includes multiple support rods 8 installed on both sides of the support frame 3. A winding box 801 and a mounting box 802 are fixedly connected between two support rods 8, respectively. A second rotary drive 803 is fixedly connected to one side of the outer wall of the mounting box 802, and a rotating rod 804 is fixedly connected to the output end of the second rotary drive 803. One end of the rotating rod 804 away from the second rotating drive 803 extends rotatably into the interior of the mounting box 802. Both sides of the outer wall of the rotating rod 804 are wound with traction ropes 805. The inside of the winding box 801 is rotatably connected with a winding shaft 806, and both ends of the winding shaft 806 extend rotatably to the outside of the winding box 801. The two ends of the winding shaft 806 are fixedly connected with a fixing plate 807. The inside of the fixing plate 807 is connected with a torsion spring 808. The outer wall of the winding shaft 806 located inside the winding box 801 is wound with a sunshade cloth 809.

[0052] The invention is further described in detail as follows: the end of the traction rope 805 away from the rotating rod 804 is connected to the sunshade cloth 809; a plurality of sliding holes are provided on one side of the mounting box 802; the end of the traction rope 805 away from the rotating rod 804 extends slidably to the outside of the mounting box 802 through the sliding holes; the end of the torsion spring 808 away from the fixed plate 807 is connected to the outer wall of the winding box 801, and the torsion spring 808 is sleeved on the outer wall of the winding shaft 806; a sliding groove is provided on one side of the winding box 801; the end of the sunshade cloth 809 away from the winding shaft 806 extends slidably to the outside of the winding shaft 806 through the sliding groove;

[0053] Working principle: In the initial state, the sunshade tarpaulin 809 is wound around the outer wall of the take-up shaft 806 and located inside the take-up box 801. At this time, the torsion spring 808 is in its natural state. When it is necessary to provide shade and protection above the first support platform 707 and the second support platform 903, the second rotary drive 803 is started in the forward direction, which drives the rotating rod 804 to rotate. The rotating rod 804 winds the traction rope 805, and the traction rope 805 pulls the sunshade tarpaulin 809 to slide out from inside the take-up box 801 through the sliding groove to achieve the shading of the charging mechanism. When the shading is not needed, the second rotary drive 803 is started in the reverse direction, the traction rope 805 is released, and under the elastic force of the torsion spring 808, the take-up shaft 806 rotates to rewind the sunshade tarpaulin 809 back into the take-up box 801.

[0054] When using this portable wireless charging platform for drone take-off and landing, the platform is moved to a suitable position using the moving wheels 2. When a medium-sized drone needs charging, it is placed on the first support platform 707, and the first rotating drive component 702 of the first lifting and charging mechanism is activated, so that the first charging head 706 contacts the first charging coil 708 for charging. When multiple small drones need charging, they are placed on the corresponding positions on the second support platform 903, and the third rotating drive component 902 of the second lifting and charging mechanism is activated, so that the second charging head 908 contacts the second charging coil 907. At the same time, the hydraulic cylinder 601 of the clamping mechanism is activated to stably clamp the small drones. During the charging process, if there is bad weather, the second rotating drive component 803 of the shielding mechanism can be activated to unfold the sunshade tarpaulin 809 for protection. After charging is completed, the charging head is disengaged from the charging coil by reversing the operation of the corresponding mechanism, and the sunshade tarpaulin 809 is retracted to complete the entire charging process.

[0055] Through the above technical solution, the shielding mechanism installed above the support frame 3 consists of a support rod 8, a winding box 801, a mounting box 802, a second rotary drive 803, a rotating rod 804, a traction rope 805, a winding shaft 806, a fixed plate 807, a torsion spring 808, and a sunshade tarpaulin 809. In the initial state, the sunshade tarpaulin 809 is wound around the outer wall of the winding shaft 806 and located inside the winding box 801, thus receiving effective protection. When needed, the second rotary drive 803 is activated by rotating forward, causing the rotating rod 804 to rotate. The traction rope 805 pulls the sunshade tarpaulin 809 out of the winding box 801 and slides it out through the sliding groove to shield the area above the first support platform 707 and the second support platform 903. This design can effectively cope with severe weather such as rain, snow, and scorching sun, providing protection for charging equipment and drones, extending the service life of the equipment, and ensuring that the charging process can proceed smoothly in various environments.

[0056] A method for using a mobile wireless charging platform for drone take-off and landing includes the following steps:

[0057] Step 1: When it is necessary to charge the medium-sized drone, start the first rotary drive 702. Its output end drives the first shaft on the U-shaped frame 701 to rotate, so that the first crank plate 704 and the second crank plate 705 are linked together, which in turn drives the first support platform 707 to move up and down reciprocally, so that the first charging head 706 contacts the first charging coil 708. At this time, the medium-sized drone placed on the first support platform 707 begins to charge.

[0058] Step 2: Start the third rotary drive 902 to drive the relevant crank plate to rotate, so that the lifting platform 905 moves up and down. When the lifting platform 905 rises and the second charging head 908 contacts the second charging coil 907, the small drone placed on the corresponding position of the second support platform 903 is charged.

[0059] Step 3: When the small drone is placed on the second support platform 903, the two hydraulic cylinders 601 are activated. The hydraulic cylinders 601 push the clamping blocks 605 to move in opposite directions, thereby driving the clamping rods 606 to clamp the small drone.

[0060] Step 4: When it is necessary to provide shade and protection above the first support platform 707 and the second support platform 903, the second rotary drive 803 is started in the forward direction, which drives the rotating rod 804 to rotate. This allows the traction rope 805 to pull the sunshade cloth 809 out of the inside of the winding box 801 through the sliding groove, thus providing shade for the charging mechanism. When shading is not needed, the second rotary drive 803 is started in the reverse direction, the traction rope 805 is released, and under the elastic force of the torsion spring 808, the winding shaft 806 rotates, rewinding the sunshade cloth 809 back into the winding box 801.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

8. A method for using a mobile wireless charging platform for take-off and landing of unmanned aerial vehicles, characterized in that, Includes the following steps: Step 1: When it is necessary to charge the medium-sized drone, start the first rotary drive (702), and its output end drives the first shaft on the U-shaped frame (701) to rotate, so that the first crank plate (704) and the second crank plate (705) are linked together, thereby driving the first support platform (707) to move up and down reciprocally, so that the first charging head (706) contacts the first charging coil (708), and the medium-sized drone placed on the first support platform (707) begins to charge. Step 2: Start the third rotary drive (902) to drive the relevant crank plate to rotate, so that the lifting platform (905) moves up and down. When the lifting platform (905) rises and the second charging head (908) contacts the second charging coil (907), the small drone placed on the corresponding position of the second support platform (903) is charged. Step 3: When the small drone is placed on the second support platform (903), the two hydraulic cylinders (601) are activated. The hydraulic cylinders (601) push the clamping blocks (605) to move in opposite directions, thereby driving the clamping rod (606) to clamp the small drone. Step 4: When it is necessary to provide shade and protection above the first support platform (707) and the second support platform (903), start the second rotary drive (803) in the forward direction, drive the rotating rod (804) to rotate, so that the traction rope (805) pulls the sunshade cloth (809) out of the inside of the take-up box (801) through the sliding groove to achieve the shading of the charging mechanism. When the shading is not needed, start the second rotary drive (803) in the reverse direction, release the traction rope (805), and under the elastic force of the torsion spring (808), the take-up shaft (806) rotates to re-roll the sunshade cloth (809) back into the take-up box (801).
