[0032] 3. As the movable plate continues to rise, the contact roller moves upward and squeezes the wedge-shaped block. The squeezing force causes the cover to flip open along the hinge and twist the torsion spring. When the contact roller contacts and squeezes the wedge-shaped block, the contact roller rotates along the rotating connection of the squeezing strip due to contact friction, thereby reducing the wear caused by squeezing. When the squeezing strip flips from the bottom of the contact roller to one side of the contact roller, the barrier bar flips from the horizontal covering state to the vertical opening state, ensuring that the drone has sufficient landing space.

DETAILED DESCRIPTION

[0048] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0049] like Figures 1 to 14 The energy-saving generator for charging drones shown in the figure includes a frame 1, an internal combustion engine 2, and a generator body 3. The internal combustion engine 2 and the generator body 3 are fixedly mounted on the frame 1. The internal combustion engine 2 and the generator body 3 are driven by a belt. The generator also includes:

[0050] The mounting shell 4 is fixedly mounted on the frame 1, and a charging connector 5 (such as Figure 5 As shown), a conductive wire is electrically connected between the charging connector 5 and the generator body 3;

[0051] The movable plate 6 is slidably connected to the interior of the mounting housing 4, and a through slot 7 is provided on the movable plate 6 (such as Figure 12 、 Figure 13 and Figure 14 As shown in the figure, the charging connector 5 is inserted into the through slot 7, and the bottom of the movable plate 6 is slidably connected to two baffles 8, which are respectively located on both sides of the charging connector 5;

[0052] Two cover plates 9, both of which are hinged to the top of the mounting housing 4;

[0053] A lifting assembly is used to drive the movable plate 6 to move vertically up and down;

[0054] The covering component drives the blocking bar 8 to cover the through slot 7 when the movable plate 6 rises;

[0055] A clamping assembly is used to clamp and position the UAV on top of the movable plate 6;

[0056] Flip assembly, when the movable plate 6 rises, the flip assembly drives the cover plate 9 to flip open;

[0057] When charging a drone with an existing generator, the drone battery usually needs to be removed and connected to the generator for charging. The staff needs to land the drone battery, remove the battery, and then manually connect the charging terminal for charging, which increases the preparation work before charging. When charging a drone in a complex outdoor environment, dust easily accumulates on the charging port, which affects the conductivity of the charging port.

[0058] 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.

[0059] 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.

[0060] 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 through the conductor cutting the magnetic flux lines. The generator body 3 and the charging connector 5 are electrically connected through the conductive wire. 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.

[0061] When charging the drone, the present invention operates the drone to land on the movable plate 6. As the movable plate 6 descends, the drone is clamped and positioned and connected to the charging connector 5, effectively reducing the preparation work before charging the drone and reducing the operating difficulty of the staff. Before the cover 9 is opened, the blocking bar 8 is driven by the action of the covering component to cover the through-groove 7, reducing dust in the external environment from falling into the charging connector 5 along the through-groove 7, thereby ensuring the current transmission stability after the charging connector 5 is connected.

[0062] As a further embodiment of the present invention, the covering assembly comprises:

[0063] Two guide plates 10 are fixedly connected to both sides of the mounting housing 4, and two guide grooves 11 are provided on the guide plates 10 (such as Figure 4 As shown), the guide slot 11 includes an expansion segment 1101, a moving segment 1102 and a blocking segment 1103, the expansion segment 1101 is located at the bottom of the moving segment 1102, and the blocking segment 1103 is located at the top of the moving segment 1102;

[0064] Two circular rods 12, the two circular rods 12 are respectively fixedly connected to the bottom of the two baffles 8, and the two ends of the circular rods 12 are respectively located in the corresponding expansion sections 1101;

[0065] When the movable plate 6 rises, the blocking bar 8 is connected to the movable plate 6 by sliding, driving the blocking bar 8 to rise synchronously. When the two ends of the circular rod 12 are respectively located inside the corresponding expansion segments 1101, the two blocking 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 intersection of the expansion segment 1101 and the movable segment 1102. As the movable plate 6 continues to rise, the circular rod 12 moves inside the movable segment 1102. The two circular rods 12 are guided by the movable segment 1102 to approach each other, and drive the two blocking bars 8 to approach each other along the sliding connection.

[0066] When the adjacent ends of the two blocking bars 8 touch, the circular rod 12 is located at the intersection of the movable section 1102 and the shielding section 1103. At this time, the through-slot 7 is completely shielded by the two blocking bars 8. The movable plate 6 continues to move upward and opens the cover plate 9 through the action of the flip assembly, so that the shielding of the through-slot 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.

[0067] Similarly, when the movable plate 6 descends, the guide groove 11 guides the circular rod 12 in the opposite direction, so that the two blocking bars 8 move away from each other and remove the obstruction of the through-groove 7, ensuring that the charging connector 5 enters the through-groove 7 and docks normally with the charging port of the drone.

[0068] As a further embodiment of the present invention, the clamping assembly comprises:

[0069] Two clamping frames 13 (such as Figure 12 As shown), the two clamping frames 13 are respectively located on both sides of the top of the movable plate 6;

[0070] Two sliding frames 14, both sliding frames 14 are slidably connected to the movable plate 6, the clamping frame 13 is fixedly connected to the corresponding sliding frame 14, and both ends of the sliding frame 14 are fixedly connected to the first rack 15 (such as Figure 5 As shown), both sides of the baffle 8 are fixedly connected to the second rack 16, and the bottom of the movable plate 6 is rotatably connected to four gears 17, which are located between the corresponding first rack 15 and second rack 16 and mesh with each other;

[0071] When the two baffles 8 approach each other and cover the through-slot 7, the baffles 8 drive the second racks 16 on both sides to move synchronously. Through the meshing action of the gear 17 and the second rack 16, the gear 17 is meshed and rotated, and in the process of rotation of the gear 17, the first rack 15 and the second rack 16 are meshed and moved in opposite directions. The first rack 15 drives the corresponding sliding frame 14 and the clamping frame 13 to move synchronously, so that when the two baffles 8 approach each other, the two clamping frames 13 move away from each other, so that the drone has sufficient space to land between the two clamping frames 13. When the two baffles 8 move away from each other, the two clamping frames 13 approach each other and contact the drone's fuselage, clamping and positioning the drone fuselage at the center of the top of the movable plate 6, so that when the movable plate 6 drives the drone to descend, the clamping frames 13 approach each other and automatically clamp and position the drone fuselage.

[0072] As a further embodiment of the present invention, the clamping frame 13 includes a horizontal arc segment 1301 and a vertical arc segment 1302 , wherein the vertical arc segment 1302 is located on top of the horizontal arc segment 1301 ;

[0073] When the two clamping frames 13 are close to each other, the horizontal arc surface segment 1301 of the clamping frame 13 performs arc surface guidance and positioning on the side of the drone fuselage, so that the drone fuselage is positioned at the center of the top of the movable plate 6, ensuring that the charging interface of the drone and the charging connector 5 can be accurately docked. At the same time, the vertical arc surface segment 1302 performs arc surface positioning on the top of the drone fuselage, thereby limiting the vertical movement of the drone, ensuring that the charging interface of the drone and the charging connector 5 are fully inserted into the charging interface of the drone during the docking process, preventing the occurrence of incomplete insertion.

[0074] As a further embodiment of the present invention, the flip assembly comprises:

[0075] Two sets of extruded strips 18 (such as Figure 4 As shown), two groups of extrusion bars 18 are fixedly connected to both sides of the top of the movable plate 6, and each group of extrusion bars 18 has two extrusion bars 18. The tops of the extrusion bars 18 are rotatably connected to contact rollers 19, and wedge blocks 20 are provided above the contact rollers 19. The wedge blocks 20 are fixedly connected to the bottoms of the corresponding cover plates 9. A torsion spring 21 is fixedly installed at the hinge between the cover plate 9 and the mounting housing 4. When the circular rod 12 is located at the intersection of the moving section 1102 and the shielding section 1103, the contact rollers 19 contact the corresponding wedge blocks 20;

[0076] By installing a torsion spring 21 at the hinge between the cover plate 9 and the mounting shell 4, the cover plate 9 is elastically covered on the top of the mounting shell 4 by the torsion force of the torsion spring 21. When the movable plate 6 is rising, the circular rod 12 moves to the intersection of the moving section 1102 and the blocking section 1103, and the two blocking bars 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 squeezes the wedge block 20, and the cover plate 9 is flipped open along the hinge by the squeezing force, and the torsion spring 21 is twisted. When the contact roller 19 contacts and squeezes the wedge block 20, the contact roller 19 rotates along the rotating connection of the squeezing bar 18 by the contact friction force, thereby reducing the wear caused by squeezing. When the wedge block 20 flips from the top of the contact roller 19 to the side of the contact roller 19, the cover plate 9 flips from the horizontal covering state to the vertical opening state, ensuring that the drone has sufficient landing space.

[0077] When the movable plate 6 descends, the extrusion bar 18 and the contact roller 19 are driven to descend synchronously, the wedge block 20 gradually loses the contact and extrusion of the contact roller 19, and under the rotation action of the torsion spring 21, drives the cover plate 9 to return to the initial position, thereby automatically covering the top of the installation shell 4.

[0078] As a further embodiment of the present invention, the lifting assembly comprises:

[0079] Two electric cylinders 22, both of which are fixedly mounted on the bottom of the mounting housing 4, and the output shafts of the electric cylinders 22 are fixedly connected to the bottom of the movable plate 6;

[0080] The two electric cylinders 22 work synchronously, so that 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 fall, the movable plate 6 moves downward and returns to the initial position.

[0081] As a further embodiment of the present invention, two groups of circular holes 23 are provided on the movable plate 6 (such as Figure 7 As shown in FIG, there are two circular holes 23 in each group, and a micro-generator 24 (as shown in FIG) is fixedly installed at the bottom of each circular hole 23. Figure 4 and Figure 10As 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 batteries 26 are fixedly installed at the bottom of the movable plate 6. The batteries 26 and the two micro-generators 24 in the same group are electrically connected by conductive wires, and the batteries 26 and the corresponding electric cylinders 22 are electrically connected by conductive wires.

[0082] The drone needs to take off and land on the top of the movable plate 6 before and after charging. During the take-off and landing process, the drone's multiple propellers are 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 hole 23, thereby driving the rotor of the micro-generator 24 to rotate and generate electricity, and the battery 26 is used to store the current generated by the micro-generator 24. When the electric cylinder 22 is working, the battery 26 is used to power the electric cylinder 22, thereby partially recovering the airflow energy generated by the drone's take-off and landing, and reducing the additional loss of the generator body 3 caused by the operation of the electric cylinder 22.

[0083] As a further embodiment of the present invention, a flow-through hole 27 (such as Figure 13 shown);

[0084] When the turbine 25 rotates during the take-off and landing of the drone, the rotation of the turbine 25 generates airflow inside the circular hole 23. Part of the airflow inside the circular hole 23 enters the through-groove 7 along the guide hole 27. At this time, the two baffles 8 cover the bottom of the through-groove 7. The airflow entering the through-groove 7 blows away the dust on the side walls of the through-groove 7 and the top of the baffles 8, preventing the dust from losing support and falling onto the charging connector 5 when the baffle 8 detaches from the bottom of the through-groove 7, and preventing the external dust received by the movable plate 6 each time it is raised and lowered from affecting the charging connector 5.

[0085] As a further embodiment of the present invention, the bottom of the mounting housing 4 is provided with two mounting holes 28 (such as Figure 10 As shown), one end of the conductive wire on the electric cylinder 22 extends along the corresponding mounting hole 28 to the inside of the mounting housing 4 and is electrically connected to the corresponding battery 26;

[0086] The conductive wire connecting the electric cylinder 22 and the battery 26 is inserted into the corresponding mounting hole 28 and has a sufficient movable length. Therefore, during the rising process of the movable plate 6, the conductive wire between the electric cylinder 22 and the battery 26 moves upward along the mounting hole 28 to ensure that the rising of the movable plate 6 is not affected.

[0087] As a further embodiment of the present invention, one end of the frame 1 is rotatably connected to two rollers 29, and the bottom of the other end of the frame 1 is fixedly connected to a support frame 30, and the bottom surface of the support frame 30 and the bottom of the rollers 29 are located at the same horizontal plane;

[0088] 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, thereby improving the stability of the drone's take-off and landing.

[0089] Working principle of the present invention:

[0090] 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.

[0091] 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.

[0092] 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.

[0093] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
