In order to increase the battery life of the drone, photovoltaic panels are installed on the drone to charge the battery in the drone, so as to increase the battery life of the drone. However, since the drone is in a tilted state when it moves, the photovoltaic panels will tilt with the drone, which will increase the resistance encountered by the drone when it moves. At the same time, due to the tilt of the photovoltaic panels, when the drone moves away from the sun, part of its position is blocked, which will affect the power supply effect of the photovoltaic panels for the drone.

[0018] Beneficial effects of the present invention:

[0019] 1. By setting a self-moving swinging member, when the drone body moves, the drone body will tilt. At this time, the movable slider moves along the guide rail or the sleeve block moves along the guide rod under the action of gravity, so that the second piston rod can push the gas inside the second sleeve into the first sleeve. At this time, the first piston rod inside the first sleeve will be pushed by the gas injected into the first sleeve to move upward, so that the positioning ball block pushes the lower side of the photovoltaic power generation panel to move upward. At this time, the ball-shaped rotating shaft will swing relative to the ball shaft connecting seat, so that the first piston rod above the first sleeve can push the photovoltaic power generation panel to be in a horizontal state, so that the photovoltaic power generation panel is always in a horizontal state, which not only reduces the resistance generated when the drone body is in operation, but also prevents the photovoltaic power generation panel from being partially blocked, further improving the charging effect of the photovoltaic power generation panel on the battery inside the drone body;

[0020] 2. By setting a disassembly unit, when installing the photovoltaic power generation panel, the threaded column is screwed into the inner side of the connecting column to achieve the left and right direction limit of the threaded column. When the threaded column is screwed into the inside of the connecting column, the wire plug will be inserted into the inside of the conductive socket. At the same time, the wire plug will rotate with the rotation of the threaded column. When the threaded column is completely screwed into the inside of the connecting column, the first through hole is aligned with the second through hole. Then, the threaded column and the connecting column are limited in the vertical direction by the positioning bolt, so as to achieve the rapid installation and disassembly of the photovoltaic power generation panel;

[0021] 3. By setting a shift locking piece, when the sleeve block moves relative to the drone body, the rotating coupling will pull or push the third piston rod, so that the gas inside the gas chamber passes through the annular disk and the annular chamber into the third sleeve, or the gas inside the third sleeve enters the gas chamber. When the sleeve block moves, the annular chamber will also rotate relative to the annular disk. When the drone body stops operating, the solenoid valve will be powered off and closed. At this time, the gas inside the third sleeve will lose its flow space, so that the third piston rod cannot move relative to the third sleeve. In this way, the sleeve block can be prevented from moving relative to the connecting chamber, thereby ensuring the stability of the sleeve block when the drone body stops operating, and preventing the sleeve block from causing the photovoltaic panel to shake when the drone body is taken and moved.

[0039] The self-moving swinging member includes a guide rail 406 installed on the inner wall of the connecting bin 401, a movable slider 418 is slidably connected to the guide rail 406, and a third telescopic spring 413 connected to the inner wall of the connecting bin 401 is arranged on the movable slider 418, a guide rod 410 is installed on one side of the movable slider 418, a sleeve block 408 is slidably connected to the guide rod 410, a positioning block 411 is installed on the sleeve block 408, and four second sleeves 416 are installed on the outer wall of the positioning block 411. The four second sleeves 416 are equidistantly distributed along the central axis of the positioning block 411, and a second piston rod 415 extending to the outside of the second sleeve 416 is inserted into the interior of the second sleeve 416, and one end of the second piston rod 415 is away from the positioning block 411 A fourth telescopic spring 414 connected to the second sleeve 416 is provided, four first sleeves 402 are installed on the outer wall of the ball-shaft connecting seat 403, and the four first sleeves 402 are equidistantly distributed along the center of the ball-shaft connecting seat 403, a first piston rod 407 extending to the top of the first sleeve 402 is inserted into the interior of the first sleeve 402, a positioning ball block 417 is installed on the top of the first piston rod 407, a first air guide tube 412 connected to the second sleeve 416 is provided at the bottom of the first sleeve 402, a first telescopic spring 405 connected to the sleeve block 408 is provided at the bottom of the spherical rotating shaft 404, and second telescopic springs 409 located outside the guide rod 410 and connected to the movable slider 418 are provided on both sides of the sleeve block 408;

[0040] When the drone body 1 moves, the drone body 1 will tilt. At this time, the movable slider 418 moves along the guide rail 406 under the action of gravity, or the sleeve block 408 moves along the guide rod 410. When the movable slider 418 slides along the guide rail 406 under the action of gravity, the second piston rod 415 vertically arranged with the guide rod 410 will contact the inner wall of the connecting chamber 401, so that the second piston rod 415 can push the gas inside the second sleeve 416 into the first sleeve 402. At this time, the first piston rod 407 inside the first sleeve 402 will be pushed by the gas injected into the first sleeve 402 and move upward, so that the positioning ball block 417 pushes the lower side of the photovoltaic panel 2 to move upward, and the spherical shaft 404 will be relative to the ball shaft The connecting seat 403 swings, and similarly, when the sleeve block 408 moves along the guide rod 410 under the action of gravity, the second piston rod 415 which is parallel to the guide rod 410 will contact the movable slider 418, so that the first piston rod 407 above the first sleeve 402 can push the photovoltaic panel 2 to be in a horizontal state, so that the photovoltaic panel 2 is always in a horizontal state, which not only reduces the resistance generated when the drone body 1 is in operation, but also prevents the photovoltaic panel 2 from being partially blocked, further improving the charging effect of the photovoltaic panel 2 on the internal battery of the drone body 1. When the drone body 1 is in a horizontal state, the photovoltaic panel 2 will be restored under the action of the elastic restoring force of the second telescopic spring 409, the third telescopic spring 413, and the first telescopic spring 405;

[0041] The first sleeve 402 is located above the second sleeve 416, and the four first sleeves 402 are connected one-to-one with the four second sleeves 416.

[0042] When the photovoltaic power generation panel 2 is in a horizontal state, there is a gap between the first piston rod 407 and the bottom of the photovoltaic power generation panel 2. This structure is provided to prevent one side of the photovoltaic power generation panel 2 from being in contact and squeezed with the rest of the first piston rod 407 when it swings due to support;

[0043] There are two guide rods 410, and the two guide rods 410 are equidistantly distributed along the transverse central axis of the movable slider 418. This structure is provided to improve the stability of the movement of the sleeve block 408.

[0047] When installing the photovoltaic power generation panel 2, the threaded column 501 is screwed into the inner side of the connecting column 503 to limit the threaded column 501 in the left and right directions. When the threaded column 501 is screwed into the inside of the connecting column 503, the wire plug 506 will be inserted into the inside of the conductive socket 507. At the same time, the wire plug 506 will rotate with the rotation of the threaded column 501. When the threaded column 501 is completely screwed into the inside of the connecting column 503, the first through hole 508 is aligned with the second through hole 509. Then, the threaded column 501 and the connecting column 503 are limited in the vertical direction by the positioning bolt 502, so as to realize the rapid installation and disassembly of the photovoltaic power generation panel 2.

[0048] The first contact piece 504 is electrically connected to the battery inside the drone body 1 through a wire, and the conductive socket 507 is electrically connected to the photovoltaic panel 2 through a wire.

[0049] Example 3

[0050] The shift locking member includes a rotating shaft 608 installed at the bottom of the sleeve block 408, a third piston rod 607 is arranged on one side of the rotating shaft 608, an annular disc 601 is installed at the bottom of the inner wall of the connecting chamber 401, an annular chamber 604 is arranged on the outer side of the annular disc 601, a third sleeve 605 located on the outer side of the third piston rod 607 is installed on the outer wall of the annular chamber 604, a second air guide pipe 606 extending to the outer side of the annular disc 601 is arranged inside the annular disc 601, one end of the second air guide pipe 606 is connected to the electromagnetic valve 603, and a gas chamber 602 connected to the connecting chamber 401 is arranged on one side of the electromagnetic valve 603;

[0051] When the sleeve block 408 moves relative to the drone body 1, the rotating coupling 608 will pull or push the third piston rod 607, so that the gas inside the gas chamber 602 enters the third sleeve 605 through the annular disc 601 and the annular chamber 604, or the gas inside the third sleeve 605 enters the gas chamber 602. When the sleeve block 408 moves, the annular chamber 604 will also rotate relative to the annular disc 601. When the drone body 1 stops operating, the solenoid valve 603 will be powered off and closed. At this time, the gas inside the third sleeve 605 will lose its flow space, so that the third piston rod 607 cannot move relative to the third sleeve 605. In this way, the sleeve block 408 can be prevented from moving relative to the connecting chamber 401, thereby ensuring the stability of the sleeve block 408 when the drone body 1 stops operating, and preventing the sleeve block 408 from driving the photovoltaic panel 2 to shake when the drone body 1 is taken and moved;

[0052] The top of the rotating shaft 608 is rotatably connected to the sleeve block 408 through a bearing, and a rotating sealing ring is provided at the connection between the annular bin 604 and the annular disc 601. This structure is provided to improve the sealing between the annular bin 604 and the annular disc 601, and prevent the air inside the gas bin 602 from being discharged through the connection between the annular bin 604 and the annular disc 601;

[0053] The air bin 602 is an elastic rubber bin structure, and the space inside the air bin 602 is larger than the space inside the third sleeve 605. By setting this structure, the air inside the air bin 602 shrinks when the air inside the air bin enters the third sleeve 605, so that the space inside the air bin 602 decreases as the gas is discharged.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
