Specific embodiments

[0031] Embodiment 1:

[0032] Please refer to Figures 1 to 2The embodiment of the present invention provides a multifunctional UAV that can be charged by solar energy, which is mainly used to ensure the stable flight and water surface support of the UAV body 1, and specifically includes a UAV body 1, a groove 4 is provided at the bottom of the UAV body 1, and a support component 5 that can contact the water surface and is used to support the UAV body 1 when landing on the water surface is arranged inside the groove 4, and a deformation component 3 is also arranged inside the groove 4 for driving the support component 5 to move out of the groove 4 and then contact the water surface; a control component 2 that provides driving force for the deformation component 3 is arranged at the bottom of the UAV body 1.

[0033] The control component 2 is configured as a support leg of the drone body 1. When the drone body 1 lands on the ground, the control component 2 supports the drone body 1. When the drone body 1 lands on the water, the control component 2 drives the support component 5 to move out of the groove 4 through the deformation component 3, and the area of ​​the support component 5 (in the vertical direction) becomes twice the original area, and this area is the contact area with the water surface. In this embodiment, a charging module (not shown in the figure) is provided on the top of the drone body 1, which can realize automatic solar charging. It and the drone body 1 are both existing mature technologies and will not be described in detail here.

[0034] See also Figures 1 to 5 In this embodiment, preferably: the control component 2 includes a bracket 201 fixedly connected to the surface of the drone body 1, a cavity 202 is provided between the bottom of the bracket 201 and the drone body 1, a floating block 203 is slidably installed inside the cavity 202, the floating block 203 has a certain weight and can rise along the bracket 201 based on the cavity 202 when it encounters water. A flexible rack 204 that is transmission-connected to the deformation component 3 is fixedly installed on the top of the floating block 203, and when the floating block 203 rises, the flexible rack 204 provides driving force for the deformation component 3.

[0035] In the above structure, the part of the cavity 202 located in the drone body 1 has a circuitous portion. When the flexible rack 204 rises with the floating block 203 and moves along the cavity 202, it can enter the circuitous portion of the cavity 202, thereby greatly reducing the space occupied by the flexible rack 204 after movement, so as to ensure the normal arrangement of components in the drone body 1.

[0036] Further, the deformation assembly 3 includes a main rod 301, a slave rod 302, a second main rod 304 and a second slave rod 305 which are rotatably connected to the groove 4 and the support assembly 5. A gear 303 which is transmission-connected to the flexible rack 204 is fixedly mounted on the outer surface of the main rod 301; Figure 3As shown, when the flexible rack 204 ascends, it drives a main rod 301 to rotate counterclockwise through a gear 303. A connecting rod 306 is rotatably connected between a secondary rod 302 and a second main rod 304. When the main rod 301 rotates, it can drive the secondary rod 302 to rotate through a support assembly 5. The secondary rod 302 drives the second main rod 304 to deflect in the opposite direction through the connecting rod 306, and the second main rod 304 drives the second secondary rod 305 to deflect synchronously in the opposite direction through the support assembly 5. That is, the rotation directions of the main rod 301 and the secondary rod 302 are the same, and the rotation directions of the second main rod 304 and the second secondary rod 305 are also the same, and they are opposite to each other.

[0037] In the above structure, as Figure 4 shown, there are respectively a first base point 307, a second base point 308, a third base point 309, and a fourth base point 310 between the main rod 301, the secondary rod 302, the second main rod 304, the second secondary rod 305 and the groove 4, and the heights of the second base point 308, the third base point 309, the first base point 307, and the fourth base point 310 decrease in sequence (when viewed from top to bottom). The connection point of the connecting rod 306 and the secondary rod 302 is located on the side of the second base point 308 away from the support assembly 5, and the connection point of the connecting rod 306 and the second main rod 304 is located on the side of the third base point 309 close to the support assembly 5, so that when the secondary rod 302 rotates, it can drive the second main rod 304 to rotate in the opposite direction through the connecting rod 306.

[0038] At the same time, the main rod 301 and the secondary rod 302 are in a coplanar state, and the main rod 304 and the secondary rod 305 are also in a coplanar state. The coplanar states of the two are offset front and back, and the main rod 301 and the secondary rod 302 are located on the outside. Based on the settings of the first base point 307 to the fourth base point 310, when in the contracted state, the second main rod 304 and the second secondary rod 305 can be located inside the main rod 301 and the secondary rod 302 (at this time, the whole is in a folded X shape), and the second main rod 304 and the second secondary rod 305 can move out from between the main rod 301 and the secondary rod 302 and deform into an open state (at this time, the whole is in an open U shape).

[0039] Further, the support assembly 5 includes an upper partition plate 502 rotatably connected to a main rod 301 and a secondary rod 302, and a base 507 rotatably connected to two main rods 304 and two secondary rods 305. The rotational connection between the two main rods 304, two secondary rods 305 and the base 507 enables the base 507 to move synchronously with the two main rods 304, so that the base 507 is moved out from above the upper partition plate 502, and the bottom of the base 507 can reach a state flush with the top of the upper partition plate 502. A long shaft 503 is rotatably installed on the side of the upper partition plate 502 away from the gear 303. An outer surface of the long shaft 503 is fixedly sleeved with a lower partition plate 501. When structures such as the main rod 301 and the secondary rod 302 are in a contracted state, the upper partition plate 502 and the lower partition plate 501 are in an overlapping state up and down. When structures such as the main rod 301 and the secondary rod 302 are in an open state, the upper partition plate 502 and the lower partition plate 501 are turned into a collinear state and the lower partition plate 501 abuts against the bottom of the base 507.

[0040] As Figure 5 shown, in order to realize the adjustment of the upper partition plate 502 and the lower partition plate 501, a pulling rope 504 fixedly wound around the outer surface of the long shaft 503 is fixedly installed on the surface of the base 507, and a long groove 506 for placing the pulling rope 504 is formed in the top of the upper partition plate 502. A reversing column 505 for reversing the pulling rope 504 is rotatably installed inside the long groove 506 and on the side close to the long shaft 503. The reversing column 505 is specifically circular and located above the pulling rope 504. When the base 507 is moved out from above the upper partition plate 502, it will drive the pulling rope 504 to move with the reversing column 505 as a turning point. When the pulling rope 504 moves with the base 507 and is straightened again after passing through the reversing column 505, the continuous movement of the base 507 at this time will pull the pulling rope 504, so that the pulling rope 504 drives the long shaft 503 to rotate clockwise, thereby driving the upper partition plate 502 and the lower partition plate 501 to turn into a collinear state. At the same time, a torsion spring is sleeved on the outer surface of the long shaft 503 to facilitate the subsequent automatic reset of the lower partition plate 501 relative to the upper partition plate 502.

[0041] Among them, in order to ensure the stable movement out of the upper partition plate 502 and the lower partition plate 501, chamfers can be formed on the left and right groove walls of the groove 4, or the upper partition plate 502 and the lower partition plate 501 are located outside the groove 4 (the bottom of the UAV body 1). And in this embodiment, the front and rear dimensions of the upper partition plate 502 and the lower partition plate 501 need to match the hollow dimensions of the bracket 201, so that the movement out of the upper partition plate 502 and the lower partition plate 501 will not collide and interfere with the bracket 201.

[0042] During use, the UAV body 1 flies normally. When it lands on the ground, the bracket 201 contacts the ground and it can land stably. When it lands on the water, water enters from the cavity 202, driving the floating block 203 and the flexible rack 204 to rise. The flexible rack 204 drives a main rod 301 to rotate through a gear 303 and move outward towards the groove 4. The main rod 301 drives the upper partition plate 502 to move synchronously and drives a secondary rod 302 to rotate in the same direction through the upper partition plate 502. The secondary rod 302 drives a second main rod 304 to rotate in the opposite direction through a connecting rod 306 and also move outward towards the groove 4. The second main rod 304 drives the base 507 to move in the opposite direction to the upper partition plate 502 and drives the second secondary rod 305 to rotate in the same direction through the base 507. Finally, the upper partition plate 502 and the lower partition plate 501 are moved out of the groove 4, and the bottom of the base 507 is flush with the top of the upper partition plate 502. When the second main rod 304 drives the base 507 and the upper partition plate 502 to move relatively far away from each other, the two ends of the pull rope 504 are in a close state in the early stage and will not drive the pull rope 504 to move. When the base 507 and the upper partition plate 502 are about to move relatively far away to the limit position, the base 507 cooperates with the reversing column 505 to pull the pull rope 504, causing the long shaft 503 to rotate. As a result, the lower partition plate 501 rotates around the long shaft 503 to a collinear state with the upper partition plate 502 and abuts against the base 507. Finally, the collinear upper partition plate 502 and lower partition plate 501 can contact the water surface, playing a role in supporting the UAV body 1.

[0043] In summary, through the cooperation of structures such as the flexible rack 204, the main rod 301, the pull rope 504, and the reversing column 505, the upper partition plate 502 and the lower partition plate 501 can be folded and retracted into the groove 4, not exposed outside the UAV body 1 and adapted to the size of the UAV body 1. Furthermore, the wind resistance can be reduced, the overall aesthetics can be improved, it is also convenient to pass through some narrow environments and ensure normal flight. When landing on the ground, the bracket 201 can play a role in stable support. When landing on the water, the upper partition plate 502 and the lower partition plate 501 can be moved out of the groove 4 and turned into a collinear state. As a result, the contact area with the water surface can be greatly increased. The contact area increases by two times, and the center line of the contact area is parallel to the center line of the UAV body in the vertical direction, ensuring that the UAV body 1 can land smoothly on the water surface. And because the contact area increases, the stability is better and the practicality is higher.

[0044] Embodiment 2:

[0045] Please refer to Figures 1 to 7, on the basis of the first embodiment, in order to improve the adaptability between the drone body 1 and the existing camera, the groove 4 is designed in a ring shape, that is, a part fixedly connected to the drone body 1 is left in the middle to detachably assemble the camera; at the same time, avoidance holes 8 are formed through the surfaces of the upper partition plate 502 and the lower partition plate 501, and the avoidance hole 8 on the upper partition plate 502 is connected to the long groove 506. When the upper partition plate 502 and the lower partition plate 501 are in an overlapping state, the camera body is located inside the avoidance hole 8. When the upper partition plate 502 and the lower partition plate 501 are moved out, there will be no collision interference with the camera due to the existence of the avoidance hole 8.

[0046] In order to ensure the contact area when the upper partition plate 502 and the lower partition plate 501 are in a collinear state, the avoidance hole 8 is designed in a cross shape as a whole. Two moving components 6 arranged symmetrically front and back are slidably installed together inside the two avoidance holes 8 on the upper partition plate 502 and the lower partition plate 501. In the initial state, the moving components 6 are located inside the avoidance hole 8 and will not interfere with the camera. A slide plate 7 slidably matched with the long groove 506 is fixedly installed on the outer surface of the pull rope 504. The slide plate 7 extends into the avoidance hole 8 and corresponds to the two moving components 6 in position. When the slide plate 7 slides along the long groove 506 and contacts the two moving components 6, the two moving components 6 can be driven to close together in the middle to close the avoidance hole 8.

[0047] Please refer to Figures 1 to 8 , in this embodiment, preferably: the moving component 6 includes an upper moving plate 602 slidably matched with the avoidance hole 8 on the upper partition plate 502 and a lower moving plate 601 slidably matched with the avoidance hole 8 on the lower partition plate 501. Springs 604 for resetting after relative movement are fixedly installed between the upper partition plate 502 and the lower moving plate 601 and the hole walls of the avoidance hole 8; at the same time, a wedge-shaped frame 603 corresponding to the position of the slide plate 7 is fixedly installed on the side wall of the upper moving plate 602. The two wedge-shaped frames 603 are arranged in opposite directions, so that when the slide plate 7 contacts the wedge-shaped frame 603, the two upper moving plates 602 can be driven to move towards the middle.

[0048] In order to ensure the synchronous movement of the upper moving plate 602 and the lower moving plate 601, the upper moving plate 602 and the lower moving plate 601 are set in a magnetic attraction state, so that when the upper moving plate 602 moves, the corresponding lower moving plate 601 can be driven to move synchronously, and the magnetic regions of the upper moving plate 602 and the lower moving plate 601 are arranged on the side close to the corresponding spring 604 (the side away from the center of the avoidance hole 8), so that the upper moving plates 602 and the lower moving plates 601 on the front and back sides will not affect each other. Among them, the magnetic attraction synchronous design is a mature existing technology and will not be elaborated here.

[0049] Furthermore, a wedge-shaped groove 701 corresponding to the two wedge-shaped frames 603 is formed on the surface of the skateboard 7 where the avoidance hole 8 is located. When the wedge-shaped groove 701 contacts the two wedge-shaped frames 603, the two upper moving plates 602 can be driven to close together to block the avoidance hole 8. At the same time, the skateboard 7 can also play a role in stabilizing the pull rope 504. Specifically, the wedge-shaped frame 603 has an inclined surface, and the inclined surfaces of the two wedge-shaped frames 603 and the wedge-shaped groove 701 as a whole are arranged in an "eight" shape.

[0050] During use, after falling onto the water surface, through the cooperation of structures such as the floating block 203, the flexible rack 204, the gear 303, and the main rod 301, the upper partition plate 502 and the lower partition plate 501 are driven to move out of the groove 4 and change from the overlapping state to the collinear state. The working process and effect of this part are the same as those in the first embodiment and will not be repeated here. The difference is that the upper partition plate 502 and the lower partition plate 501 still maintain the overlapping state in the initial stage of movement. At this time, the movement of the upper partition plate 502 and the lower partition plate 501 in cooperation with the avoidance hole 8 will not interfere with the camera. When the upper partition plate 502 and the lower partition plate 501 move below the camera, the base 507 will drive the skateboard 7 to move in the direction of the wedge-shaped frame 603 through the pull rope 504 and the reversing column 505. Finally, the wedge-shaped groove 701 contacts the wedge-shaped groove 701, thereby driving the two upper moving plates 602 to close towards the middle. At the same time, under the magnetic attraction, the two lower moving plates 601 can move synchronously, so that the avoidance holes 8 on the upper partition plate 502 and the lower partition plate 501 are all closed.

[0051] In the first embodiment, although the state change of the upper partition plate 502 and the lower partition plate 501 can be realized to meet the requirements of water surface landing and normal flight, since the bottom of the UAV body 1 often needs to be equipped with a camera to meet the imaging requirements, if the upper partition plate 502 and the lower partition plate 501 are not adjusted, there will be a collision interference with the camera body, thereby affecting the normal use of the whole, and there are certain limitations in use.

[0052] Compared with the first embodiment, through the cooperation of structures such as the pull rope 504, the sliding plate 7, the wedge-shaped frame 603, and the upward moving plate 602, when the upper partition plate 502 and the lower partition plate 501 are in a folded state and retracted into the groove 4, the upward moving plate 602 and the downward moving plate 601 are hidden in the avoidance hole 8 and will not collide or interfere with the camera, nor will they affect the shooting range of the camera, and will not generate resistance to the flight of the UAV body 1. When it falls on the water surface, the upper partition plate 502 and the lower partition plate 501 first move synchronously to cooperate with the avoidance hole 8 to separate from the camera, and then the upper partition plate 502 and the lower partition plate 501 are converted into a collinear state. When converted into a collinear state, the upward moving plate 602 and the downward moving plate 601 can be driven to close towards the middle to block the avoidance hole 8, thereby ensuring the contact area with the water surface and ensuring that the UAV body 1 can land smoothly on the water surface. And because the upper partition plate 502 and the lower partition plate 501 are located below the camera after being collinear, the camera will not get water when falling on the water surface. The overall operation is combined with the movement of the pull rope 504 and the settings of the upper partition plate 502 and the lower partition plate 501, and the applicability is stronger.

[0053] Embodiment Three:

[0054] Please refer to Figures 1 to 10 , on the basis of the second embodiment, in order to further increase the contact area with the water surface, side plates 9 are slidably installed on the sides of the upper partition plate 502 and the lower partition plate 501 away from the long axis 503. At this time, the avoidance hole 8 is provided with a through hole on the corresponding side for the sliding assembly of the side plates 9. The side plates 9 can slide out of the upper partition plate 502 / lower partition plate 501, thereby increasing the contact area.

[0055] In order to realize the sliding out and reset of the side plates 9, a rhombic groove 901 is formed on the side of the side plates 9 close to the long axis 503. At the same time, rhombic blocks 605 that are movably attached to the rhombic groove 901 are fixedly installed on the sides of the upward moving plate 602 and the downward moving plate 601 away from the long axis 503. When the upward moving plate 602 / downward moving plate 601 closes towards the middle, it can drive the rhombic blocks 605 to move synchronously, and then cooperate with the rhombic groove 901 to drive the side plates 9 to slide out of the upward moving plate 602 / downward moving plate 601. When the upward moving plate 602 / downward moving plate 601 separates to both sides, the side plates 9 can be driven to reset through the rhombic blocks 605 and the rhombic groove 901.

[0056] Please refer to Figures 1 to 10 , in this embodiment, preferably: both the rhombic groove 901 and the rhombic block 605 are designed as parallelograms, and the length dimension of the rhombic groove 901 is greater than the length dimension of the rhombic block 605, so that when the rhombic block 605 moves, it first separates from the side of the rhombic groove 901 close to the spring 604, moves along the rhombic groove 901, and finally contacts the side of the rhombic groove 901 away from the spring 604, thereby driving the side plates 9 to move through the rhombic groove 901.

[0057] During use, after it lands on the water surface, through the cooperation of structures such as the floating block 203, flexible rack 204, gear 303, and a main rod 301, the upper partition plate 502 and the lower partition plate 501 are driven to move out of the groove 4 and turn into a collinear state. Through the cooperation of structures such as the upper moving plate 602, lower moving plate 601, pulling rope 504, and sliding plate 7, the upper moving plate 602 and the lower moving plate 601 are driven to close towards the middle to close the avoidance hole 8 to ensure the contact area. The working process and effect of this part are the same as those in the second embodiment and will not be repeated here. The difference is that when the upper moving plate 602 and the lower moving plate 601 close towards the middle and start to close the avoidance hole 8, the diamond block 605 can be driven to move synchronously. The diamond block 605 cooperates with the diamond groove 901 to drive the side plate 9 to slide out from the side of the upper partition plate 502 / lower partition plate 501; when the upper moving plate 602 and the lower moving plate 601 reset to both sides, the side plate 9 can be driven to automatically reset and hide inside the upper partition plate 502 / lower partition plate 501 through the diamond block 605 and the diamond groove 901.

[0058] In the second embodiment, although the installation of the camera can be adapted by adjusting the upper partition plate 502 and the lower partition plate 501, the contact area with the water surface still needs to be improved so as to ensure that the drone body 1 can land smoothly on the water surface after the camera is installed.

[0059] Compared with the second embodiment, through the cooperation of structures such as the upper moving plate 602, avoidance hole 8, diamond block 605, and diamond groove 901, when the upper moving plate 602 and the lower moving plate 601 close towards the middle and start to close the avoidance hole 8, the side plate 9 can be driven to slide out from the side of the upper partition plate 502 / lower partition plate 501 to increase the contact area with the water surface, thereby improving the support effect to ensure that the drone body 1 can also land smoothly on the water surface after the camera is installed; when the upper moving plate 602 and the lower moving plate 601 reset to both sides, the side plate 9 can be driven to automatically reset and hide inside the upper partition plate 502 / lower partition plate 501, which will not affect the automatic reset of the upper partition plate 502 / lower partition plate 501 relative to the groove 4 and the camera body. The overall operation is combined with the movement and setting of the upper moving plate 602 / lower moving plate 601, meeting more requirements in actual use.
