Detailed implementation manner

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] As Figures 1 to 14 shown, an energy-saving generator for charging an unmanned aerial vehicle includes a frame 1, an internal combustion engine 2, and a main generator body 3. The internal combustion engine 2 and the main generator body 3 are both fixedly installed on the frame 1, and the internal combustion engine 2 and the main generator body 3 are driven by a belt. It further includes: An installation housing 4, which is fixedly installed on the frame 1. A charging connector 5 (as Figure 5 shown) is fixedly connected to the bottom surface inside the installation housing 4, and a conduction wire is electrically connected between the charging connector 5 and the main generator body 3; A movable plate 6, which is slidably connected inside the installation housing 4. A through groove 7 (as Figure 12 , Figure 13 and Figure 14 shown) is formed on the movable plate 6. The charging connector 5 is inserted into the through groove 7. Two retaining strips 8 are slidably connected to the bottom of the movable plate 6, and the two retaining strips 8 are respectively located on both sides of the charging connector 5; Two cover plates 9, both of which are hinged to the top of the installation housing 4; A lifting assembly, which is used to drive the vertical lifting of the movable plate 6; A covering assembly, which drives the retaining strip 8 to cover the through groove 7 when the movable plate 6 rises; A clamping assembly, which is used to clamp and position the unmanned aerial vehicle on the top of the movable plate 6; A flipping assembly, which drives the cover plate 9 to flip and open when the movable plate 6 rises; When the existing generator charges the drone, it usually needs to disconnect the drone battery and then connect it to the generator for charging. The staff needs to land the drone battery and disconnect it, and then manually dock the charging end for charging, which increases the preparatory work before charging. When the drone is charged in a complex outdoor environment, dust is likely to accumulate at the charging interface, thus affecting the conductivity of the charging interface. Before the drone is charged, the lifting assembly drives the movable plate 6 to rise vertically. During the rising process of the movable plate 6, the through slot 7 moves towards the top of the charging connector 5. After the through slot 7 is completely above the charging connector 5, the two blocking strips 8 approach each other under the action of the covering assembly and block the through slot 7. After the blocking strips 8 cover the through slot 7, the movable plate 6 continues to move upward and drives the cover plate 9 at the top of the mounting housing 4 to flip open along the hinge under the action of the flipping assembly. After the cover plate 9 is opened, the staff operates the drone to land on the top of the movable plate 6, and then drives the movable plate 6 to move downward and return to the initial position through the action of the lifting assembly. During the downward movement of the movable plate 6, the clamping assembly works to clamp and position the fuselage of the drone on the top of the movable plate 6, and drives the cover plate 9 to close along the hinge through the action of the flipping assembly. When the movable plate 6 continues to move downward, the two blocking strips 8 move away from each other under the action of the covering assembly and release the block on the through slot 7, so that when the movable plate 6 descends, the insertion end of the charging connector 5 moves above the through slot 7 and is inserted into the charging slot of the drone. After the drone is connected to the charging connector 5, the power of the internal combustion engine 2 is transmitted to the rotor of the generator main body 3 through the pulley and belt, so that the rotor of the generator main body 3 rotates, and current is generated by the conductor cutting the magnetic induction line. The generator main body 3 and the charging connector 5 are electrically connected through the conduction wire. After the generator main body 3 generates electricity, the current is transmitted to the charging connector 5 through the conduction wire and the drone is continuously charged. When the present invention charges the drone, by operating the drone to land on the movable plate 6, the clamping and positioning of the drone and the insertion of the charging connector 5 are completed as the movable plate 6 descends, effectively reducing the preparatory work before charging the drone and reducing the operation difficulty of the staff. Before the cover plate 9 is opened, the blocking strips 8 are driven by the covering assembly to cover the through slot 7, reducing the dust in the external environment from falling into the charging connector 5 along the through slot 7 and ensuring the current transmission stability after the charging connector 5 is inserted.

[0023] As a further embodiment of the present invention, the covering assembly includes: Two guiding plates 10, the two guiding plates 10 are respectively fixedly connected to both sides inside the mounting housing 4, and two guiding slots 11 are provided on each of the guiding plates 10 (as Figure 4As shown in the figure, the guiding groove 11 includes an unfolding section 1101, a moving section 1102, and a shielding section 1103. The unfolding section 1101 is located at the bottom of the moving section 1102, and the shielding section 1103 is located at the top of the moving section 1102; Two circular rods 12, the two circular rods 12 are respectively fixedly connected to the bottoms of the two retaining bars 8, and both ends of the circular rod 12 are respectively located in the corresponding unfolding sections 1101; When the movable plate 6 rises, through the sliding connection between the retaining bar 8 and the movable plate 6, the retaining bar 8 is driven to rise synchronously. When both ends of the circular rod 12 are respectively located inside the corresponding unfolding sections 1101, the two retaining bars 8 are respectively located on both sides of the bottom of the through groove 7. When the movable plate 6 moves upward so that the charging connector 5 is completely located below the through groove 7, the circular rod 12 is located at the junction of the unfolding section 1101 and the moving section 1102. During the continuous upward movement of the movable plate 6, the circular rod 12 moves inside the moving section 1102. Under the guiding action of the moving section 1102, the two circular rods 12 approach each other, and the two retaining bars 8 are driven to approach each other along the sliding connection; When the adjacent ends of the two retaining bars 8 come into contact, the circular rod 12 is located at the junction of the moving section 1102 and the shielding section 1103. At this time, the through groove 7 is completely shielded by the two retaining bars 8. The movable plate 6 continues to move upward and opens the cover plate 9 through the action of the flipping assembly, so that the shielding of the through groove 7 and the opening of the cover plate 9 are carried out in sequence, reducing the contact between external dust and the charging connector 5; Similarly, when the movable plate 6 descends, through the reverse guiding action of the guiding groove 11 on the circular rod 12, the two retaining bars 8 move away from each other and release the shielding of the through groove 7, ensuring that the charging connector 5 enters the through groove 7 and is normally docked with the charging interface of the drone.

[0024] As a further embodiment of the present invention, the clamping assembly includes: Two clamping frames 13 (as Figure 12 shown), the two clamping frames 13 are respectively located on both sides of the top of the movable plate 6; Two sliding frames 14, the two sliding frames 14 are both slidably connected to the movable plate 6. The clamping frame 13 is fixedly connected to the corresponding sliding frame 14. Both ends of the sliding frame 14 are fixedly connected with a first rack 15 (as Figure 5 shown). Both sides of the retaining bar 8 are fixedly connected with a second rack 16. Four gears 17 are rotatably connected to the bottom of the movable plate 6. The gears 17 are located between the corresponding first rack 15 and second rack 16 and mesh with each other; When the two stop bars 8 approach each other and cover the through groove 7, the stop bars 8 drive the second racks 16 on both sides to move synchronously. Through the meshing action of the gear 17 and the second racks 16, the gear 17 meshes and rotates. During the rotation of the gear 17, through the meshing action with the first rack 15, the first rack 15 moves in the opposite direction to the second racks 16. The first rack 15 drives the corresponding sliding frame 14 and the clamping frame 13 to move synchronously. Thus, when the two stop bars 8 approach each other, the two clamping frames 13 move away from each other, enabling the drone to have sufficient space to land between the two clamping frames 13. When the two stop bars 8 move away from each other, the two clamping frames 13 approach each other and contact the fuselage of the drone, clamping and positioning the fuselage of the drone at the center of the top of the movable plate 6. Thus, when the movable plate 6 drives the drone to descend, the clamping frames 13 approach each other and automatically clamp and position the fuselage of the drone.

[0025] As a further embodiment of the present invention, the clamping frame 13 includes a horizontal arc surface section 1301 and a vertical arc surface section 1302, and the vertical arc surface section 1302 is located at the top of the horizontal arc surface section 1301; When the two clamping frames 13 approach each other, the horizontal arc surface section 1301 of the clamping frame 13 guides and limits the side surface of the fuselage of the drone in an arc shape, positioning the fuselage of the drone at the center of the top of the movable plate 6 to ensure that the charging interface of the drone can be accurately docked with the charging connector 5. At the same time, the vertical arc surface section 1302 limits the top of the fuselage of the drone in an arc shape, thereby restricting the vertical movement of the drone and ensuring that during the docking process of the charging interface of the drone and the charging connector 5, the charging connector 5 can be fully inserted into the charging interface of the drone to prevent the situation of incomplete insertion.

[0026] As a further embodiment of the present invention, the flipping assembly includes: Two groups of extrusion bars 18 (as Figure 4 shown), the two groups of extrusion bars 18 are respectively fixedly connected to both sides of the top of the movable plate 6. The number of each group of extrusion bars 18 is two. A contact roller 19 is rotatably connected to the top of each extrusion bar 18. A wedge-shaped block 20 is arranged above the contact roller 19. The wedge-shaped block 20 is fixedly connected to the bottom of the corresponding cover plate 9. A torsion spring 21 is fixedly installed at the hinge of the cover plate 9 and the installation housing 4. When the circular rod 12 is located at the junction of the moving section 1102 and the shielding section 1103, the contact roller 19 contacts the corresponding wedge-shaped block 20; By installing a torsion spring 21 at the hinge joint between the cover plate 9 and the installation housing 4, the cover plate 9 is elastically covered on the top of the installation housing 4 by the torsion force of the torsion spring 21. During the upward movement of the movable plate 6, when the circular rod 12 moves to the junction of the moving section 1102 and the shielding section 1103, the two blocking strips 8 approach each other and cover the through groove 7. At this time, the contact roller 19 contacts the corresponding wedge block 20, and when the movable plate 6 continues to rise, the contact roller 19 moves upward and presses the wedge block 20. Through the extrusion force, the cover plate 9 is flipped open along the hinge joint, and the torsion spring 21 is twisted. When the contact roller 19 contacts and presses the wedge block 20, the contact roller 19 rotates along the rotating joint of the extrusion strip 18 through the contact friction force, thereby reducing the wear caused by extrusion. When the wedge block 20 is flipped from the top of the contact roller 19 to one side of the contact roller 19, the cover plate 9 is flipped from the horizontal covering state to the vertical open state, ensuring that the drone has sufficient landing space; When the movable plate 6 descends, it drives the extrusion strip 18 and the contact roller 19 to descend synchronously. The wedge block 20 gradually loses the contact extrusion of the contact roller 19, and under the rotation action of the torsion spring 21, it drives the cover plate 9 to return to the initial position, thereby automatically covering the top of the installation housing 4.

[0027] As a further embodiment of the present invention, the lifting assembly includes: Two electric cylinders 22, both of the two electric cylinders 22 are fixedly installed at the bottom of the installation housing 4, and the output shafts of the electric cylinders 22 are fixedly connected to the bottom of the movable plate 6; By the synchronous operation of the two electric cylinders 22, the piston shafts of the electric cylinders 22 rise and drive the movable plate 6 to move upward synchronously. When the piston shafts of the electric cylinders 22 descend, the movable plate 6 moves downward and returns to the initial position.

[0028] As a further embodiment of the present invention, two groups of circular holes 23 are formed in the movable plate 6 (as Figure 7 shown), the number of each group of circular holes 23 is two, and a micro generator 24 is fixedly installed at the bottom of each circular hole 23 (as Figure 4 and Figure 10 shown). A turbine 25 is fixedly connected to the rotor of the micro generator 24, and the turbine 25 is located inside the corresponding circular hole 23. Two storage batteries 26 are fixedly installed at the bottom of the movable plate 6. Conductive wires are electrically connected between the storage batteries 26 and the two micro generators 24 in the same group, and conductive wires are electrically connected between the storage batteries 26 and the corresponding electric cylinders 22; Before and after the UAV finishes charging, it needs to take off and land on the top of the movable plate 6 respectively. During the takeoff and landing processes, multiple propellers of the UAV are respectively located above the corresponding circular holes 23, and the airflow generated by the rotation of the propellers drives the turbine 25 to rotate inside the circular holes 23, thereby driving the rotor of the micro-generator 24 to rotate and generate electricity, and using the storage battery 26 to store the current generated by the micro-generator 24. When the electric cylinder 22 works, the storage battery 26 supplies power to the operation of the electric cylinder 22, so as to partially recover the airflow energy generated by the takeoff and landing of the UAV, and reduce the additional loss caused by the operation of the electric cylinder 22 to the generator body 3.

[0029] As a further implementation scheme of the present invention, a diversion through hole 27 is opened between the side surface of the through groove 7 and the circular hole 23 (as Figure 13 shown); When the turbine 25 rotates during the takeoff and landing of the UAV, the turbine 25 rotates to generate airflow inside the circular hole 23. Part of the airflow inside the circular hole 23 enters the through groove 7 along the diversion through hole 27. At this time, the two retaining strips 8 cover the bottom of the through groove 7, and the airflow entering the through groove 7 blows away the dust on the side wall of the through groove 7 and the top of the retaining strip 8, preventing the dust from falling on the charging connector 5 when the retaining strip 8 detaches from the bottom of the through groove 7, and preventing the external dust received during each lifting of the movable plate 6 from affecting the charging connector 5.

[0030] As a further implementation scheme of the present invention, two mounting holes 28 are opened at the bottom of the mounting housing 4 (as Figure 10 shown), and one end of the conducting wire on the electric cylinder 22 extends into the mounting housing 4 along the corresponding mounting hole 28 and is electrically connected to the corresponding storage battery 26; The conducting wire connecting the electric cylinder 22 and the storage battery 26 is inserted into the corresponding mounting hole 28 and has sufficient moving length, so that during the rising process of the movable plate 6, the conducting wire between the electric cylinder 22 and the storage battery 26 moves upward along the mounting hole 28 to ensure that the rising of the movable plate 6 is not affected.

[0031] As a further implementation scheme of the present invention, two rollers 29 are rotatably connected to one end of the frame 1, and a support frame 30 is fixedly connected to the bottom of the other end of the frame 1. The bottom surface of the support frame 30 and the bottom of the rollers 29 are located on the same horizontal plane; By connecting the rollers 29 to the frame 1, the convenience of moving the frame 1 is improved, and the frame 1 is supported by the support frame 30 to prevent the frame 1 from tilting and improve the stability of the takeoff and landing of the UAV.

[0032] The working principle of the present invention: Before charging, the lifting assembly drives the movable plate 6 to rise vertically. During the rising process, the through-slot 7 moves toward the top of the charging connector 5. After the through-slot 7 is completely above the charging connector 5, the two blocking bars 8 move closer to each other through the action of the covering assembly and block the through-slot 7. After the blocking bars 8 block the through-slot 7, the movable plate 6 continues to move upward and drives the cover plate 9 on the top of the mounting housing 4 to flip open along the hinge through the action of the flip assembly. After the cover 9 is opened, the staff operates the drone to land on the top of the movable plate 6, and then drives the movable plate 6 to move downward and return to the initial position through the action of the lifting assembly. During the downward movement of the movable plate 6, the clamping assembly works to clamp the drone's fuselage and position it on the top of the movable plate 6, and drives the cover 9 to close along the hinge through the action of the flip assembly. When the movable plate 6 continues to move downward, the two blocking bars 8 move away from each other through the action of the covering assembly and release the obstruction of the through-slot 7. Therefore, when the movable plate 6 descends, the plug-in end of the charging connector 5 moves to the top of the through-slot 7 and is inserted into the charging slot of the drone. After the drone is connected to the charging connector 5, the power of the internal combustion engine 2 is transmitted to the rotor of the generator body 3 through the pulley and belt, causing the rotor of the generator body 3 to rotate and generate current by cutting the magnetic lines of force through the conductor. The generator body 3 and the charging connector 5 are electrically connected through the conductive wire, so that after the generator body 3 generates electricity, the conductive wire is used to transmit the current to the charging connector 5, and the drone is continuously charged.
