Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular is a multifunctional platform for taking off and landing unmanned aerial vehicles. Background Art

[0002] UAV is the abbreviation of unmanned aircraft. It has the advantages of small size and easy use. At present, UAVs have been widely used in many fields. UAVs need a platform with a certain area when taking off and landing to ensure their horizontal posture. Nowadays, UAVs are widely used in aerial photography and agricultural fields, and often need to perform operations in mountainous areas, fields or car roofs.

[0003] However, the roads in mountainous areas and fields are uneven. Therefore, when the existing UAV take-off and landing platform is placed in mountainous areas or fields with uneven roads, the platform carrying the UAV will be in a tilted state, and the car will also tilt during driving, making it difficult to ensure that the carrying platform is level, and thus it is difficult to ensure that the UAV takes off and lands smoothly, which can easily cause the UAV to be scratched and damaged during take-off and landing. The UAV will be affected by external wind during take-off and landing, causing the UAV to be unable to take off and land normally. In actual operation, the UAV may be affected by speed and wind, causing the UAV to jump up and down and hit the carrying platform when landing on it, causing damage to the UAV. In addition, due to the harsh surrounding environment, the wings of the UAV are easily broken, and the spare wings are generally placed in a warehouse, and users cannot quickly replace them.

[0004] By setting up limit buffers and angle adjustment mechanisms, the drone can take off and land from different angles and perform buffering during takeoff and landing. The drone can also be charged and positioned through wireless charging. After the drone stops, the drone can be fixed to the top of the device to prevent it from falling when the vehicle is driving or the external environment is harsh. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention cooperates with structures such as mounting blocks, buffer rods, and collars so that when the drone body lands and presses the landing platform, the landing platform drives the connecting seat and the spherical rod to press down, and the downward pressing force is directed to the reset spring through the two sets of first connecting rods and the collar. Since the reset spring has a restoring force, the distance moved by the collar can be reset, thereby reducing the impact of the drone body landing on the landing platform caused by vibration, and ensuring that it can take off and land stably. Furthermore, when the drone body takes off, it is necessary to ensure the stability of the landing platform, start the first servo motor to drive the bidirectional screw rod to rotate, and then change the positions of the first limit block and the second limit block, so that the collar movement is limited by its own shape and the extension block. The first and second limit blocks are moved to the positions of the two sets of collars during takeoff, thereby preventing the collars from moving and ensuring the stability of takeoff. After takeoff, the collars are reset to facilitate the subsequent buffering and recovery of the drone body. Furthermore, when the device is installed in an uneven scene, it is necessary to adjust the angle of the take-off and landing platform to ensure the normal take-off and landing of the drone body. At this time, the first servo motor is started to drive the first limit block and the second limit block to move toward each other, so that the distance between the two sets of collars is shortened, thereby adjusting the angle of the end, and four sets are provided to ensure the stability of the angle adjustment, so as to achieve the purpose of facilitating the device to perform buffering landing, stabilizing take-off and adjusting the take-off and landing angles of the drone body.

[0019] The present invention arranges the coordination of structures such as the second connecting rod, the hook, and the second servo motor, so that the device can start the second servo motor to drive the second connecting rod and the hook to rotate after the drone body stops steadily, so that the hook can fix the drone body to the top of the take-off and landing platform through its own shape after rotation, so that it will not fall off, thereby achieving the purpose of facilitating the device to limit the drone body.

[0020] The present invention cooperates with structures such as the first cylinder, the wireless magnetic ring charging mother seat, and the wireless magnetic ring charging sub-seat, so that when the drone body lands, the device can, because the wireless magnetic ring charging sub-seat at the bottom of the drone body and the wireless magnetic ring charging mother seat have magnetic attraction, so that the user only needs to operate the drone body to align the approximate position, and then the magnetic force of the wireless magnetic ring charging mother seat and the wireless magnetic ring charging sub-seat can adsorb and position it when the drone body is closed, so that the position of the rack can be accurately hooked, and the drone body can be wirelessly charged. When charging is completed, the first cylinder is started to shrink the position of the wireless magnetic ring charging mother seat, and the wireless magnetic ring charging mother seat is powered off. At this time, the drone body can be controlled to take off without being affected by the magnetic force of the wireless magnetic ring charging mother seat and the wireless magnetic ring charging sub-seat, so as to achieve the purpose of facilitating the device to wirelessly charge the drone body and locate its landing position at the same time.

[0021] The present invention arranges the cooperation of the second cylinder, the storage plate, the storage slot and other structures, so that the device can recover the drone body when the wing of the drone body is damaged, and start the second cylinder to push the storage plate, so that the storage slot and the spare wing are exposed, and the user takes the spare wing for replacement, which effectively avoids the spare wing being placed in the car or warehouse, which is too troublesome for the user to replace and the position of the spare wing is easily forgotten, thereby achieving the purpose of facilitating the user to use the device to quickly replace the wing.

[0035] The above scheme is adopted: by starting the luminous positioning ring 4, the luminous positioning ring 4 can emit a conspicuous light, so that the camera carried by the drone body 6 can accurately locate the position of the device, thereby facilitating the landing of the drone body 6.

[0036] like Figures 1 to 10As shown, the buffer adjustment mechanism 2 includes a mounting block 201, a buffer rod 202 and a ring 203. The mounting block 201 is provided with two groups fixed on the top of the base plate 1. The buffer rod 202 is fixed on the outside of the mounting block 201. The buffer rod 202 is sleeved on the outside of the buffer rod 202. The top of the ring 203 is hinged with a first connecting rod 204. The mounting block 201 is provided with four groups. The mounting blocks 201 are symmetrically distributed about the central axis of the base plate 1. The inner wall of the ring 203 is close to the outer wall of the buffer rod 202. The ring 203 and the buffer rod 202 are slidably connected. The ring 203 and the first connecting rod 204 are provided with two groups. The ring 203 and the first connecting rod 204 are symmetrically distributed about the central axis of the spherical rod 205.

[0037] like Figures 1 to 10 As shown, the top end of the first connecting rod 204 is hinged with a spherical rod 205, and the top end of the spherical rod 205 is movably connected with a connecting seat 206. The outer sleeve of the buffer rod 202 is provided with a reset spring 207, and the connecting seat 206 is fixed to the bottom end of the lifting and landing platform 3. Four groups of connecting seats 206 are arranged, and the connecting seats 206 are evenly spaced about the central axis of the lifting and landing platform 3. The reset spring 207 is used to squeeze the ring 203 and keep it moving toward the position of the central axis of the buffer rod 202. Two groups of reset springs 207 are arranged, and the reset springs 207 are symmetrically distributed about the central axis of the buffer rod 202.

[0038] like Figures 1 to 10 As shown, a first servo motor 208 is fixed to the outside of the mounting block 201, a bidirectional screw rod 209 is fixed to the output end of the first servo motor 208, the external thread of the bidirectional screw rod 209 is connected to a first limit block 210, the external thread of the bidirectional screw rod 209 is connected to a second limit block 211, an extension block 212 is fixed to the bottom end of the collar 203, the outer wall of the bidirectional screw rod 209 is close to the inner wall of the mounting block 201, the bidirectional screw rod 209 and the mounting block 201 are rotatably connected, and the first limit block 210 and the second limit block 211 are symmetrically distributed about the central axis of the bidirectional screw rod 209.

[0039] The above scheme is adopted: when the take-off and landing platform 3 is pressed by the landing of the drone body 6, the take-off and landing platform 3 drives the connecting seat 206 and the spherical rod 205 to press down, and guides the downward pressure to the reset spring 207 through the two sets of first connecting rods 204 and the ring 203. Since the reset spring 207 has a restoring force, it can reset the moving distance of the ring 203, thereby reducing the impact of the landing of the drone body 6 on the vibration of the take-off and landing platform 3, and ensuring that it can take off and land stably. When the drone body 6 takes off, the first servo motor 208 is started to drive the bidirectional screw rod 209 to rotate, and then The positions of the first limit block 210 and the second limit block 211 are changed so that the movement position of the ring 203 is limited by their own shapes and the extension block 212. Then, during takeoff, the first limit block 210 and the second limit block 211 are moved to the side of the two groups of rings 203 to prevent the rings 203 from moving. After takeoff, they are reset to facilitate subsequent buffering and recovery of the drone body 6. The first servo motor 208 is started to drive the first limit block 210 and the second limit block 211 to move toward each other, so that the distance between the two groups of rings 203 is shortened, thereby being able to adjust the angle of the end.

[0040] like Figures 1 to 10 As shown, the limiting mechanism 5 includes a second connecting rod 501, a hook 502 and a second servo motor 503. The second connecting rod 501 is movably connected to the inside of the lifting and landing platform 3. The hook 502 is fixed to the outside of the second connecting rod 501. The second servo motor 503 is fixed to the outside of the second connecting rod 501. The second connecting rod 501 and the lifting and landing platform 3 are rotatably connected. Two groups of hooks 502 are arranged. The hooks 502 are symmetrically distributed about the central axis of the second connecting rod 501. The second connecting rod 501 is arranged with two groups. The second connecting rod 501 is symmetrically distributed about the central axis of the lifting and landing platform 3.

[0041] The above solution is adopted: the second servo motor 503 is started to drive the second connecting rod 501 and the hook 502 to rotate, so that the hook 502 fixes the drone body 6 on the top of the take-off and landing platform 3 through its own shape after rotation.

[0042] like Figures 1 to 10 As shown, the positioning mechanism 7 includes a first cylinder 701, a wireless magnetic ring charging mother seat 702 and a wireless magnetic ring charging sub-seat 703. The first cylinder 701 is fixed to the top of the take-off and landing platform 3. The top of the first cylinder 701 is fixed with a wireless magnetic ring charging mother seat 702, and the wireless magnetic ring charging sub-seat 703 is fixed to the bottom of the drone body 6.

[0043] The above scheme is adopted: the magnetic force of the wireless magnetic ring charging mother seat 702 and the wireless magnetic ring charging sub-seat 703 can be used to adsorb and position the drone body 6 when it is closed, so that the position of the frame can be accurately caught by the hook 502, and the drone body 6 can be wirelessly charged. When the charging is completed, the first cylinder 701 is started to shrink the position of the wireless magnetic ring charging mother seat 702, and the wireless magnetic ring charging mother seat 702 is powered off. At this time, the drone body 6 can be controlled to take off without being affected by the magnetic force of the wireless magnetic ring charging mother seat 702 and the wireless magnetic ring charging sub-seat 703.

[0044] like Figures 1 to 10 As shown, the storage mechanism 8 includes a second cylinder 801, a storage plate 802 and a storage groove 803. The second cylinder 801 is fixed inside the take-off and landing platform 3. The storage plate 802 is fixed outside the second cylinder 801. The top of the storage plate 802 is provided with a storage groove 803. The storage groove 803 is installed inside the spare wing 804. The second cylinder 801 is provided with two groups. The second cylinder 801 is symmetrically distributed about the central axis of the storage plate 802. The storage plate 802 is provided with two groups. The storage plate 802 is symmetrically distributed about the central axis of the take-off and landing platform 3. The storage groove 803 is provided with three groups.

[0045] The above solution is adopted: by starting the second cylinder 801 to push the storage plate 802, the storage slot 803 and the spare wing 804 are exposed to the outside, and the user takes the spare wing 804 for replacement.

[0046] The working principle and use process of the present invention are as follows: when the user operates the drone body 6 to land, the drone body 6 will press the landing platform 3 when it lands, and the landing platform 3 drives the connecting seat 206 and the spherical rod 205 to press down, and guides the downward pressure to the reset spring 207 through the two sets of first connecting rods 204 and the ring 203. Since the reset spring 207 has a restoring force, it can reset the moving distance of the ring 203, thereby reducing the impact of the landing of the drone body 6 on the landing platform 3 and ensuring that it can take off and land stably. Further, when the drone body 6 takes off, When the stability of the take-off and landing platform 3 needs to be ensured, the first servo motor 208 is started to drive the bidirectional screw rod 209 to rotate, thereby changing the position of the first limit block 210 and the second limit block 211, so that the position of the movement of the ring 203 is limited by its own shape and the extension block 212, and then during take-off, the first limit block 210 and the second limit block 211 are moved to the side of the two groups of rings 203, thereby preventing the ring 203 from moving, thereby ensuring the stability of take-off, and resetting it after taking off to facilitate the subsequent buffering and recovery of the drone body 6. Furthermore, the device is installed In uneven scenes, it is necessary to adjust the angle of the take-off and landing platform 3 to ensure the normal take-off and landing of the drone body 6. At this time, the first servo motor 208 is started to drive the first limit block 210 and the second limit block 211 to move toward each other, so that the distance between the two sets of rings 203 is shortened, so that the angle of the end can be adjusted, and the stability of the angle adjustment is ensured by providing four sets. When the drone body 6 lands, the wireless magnetic ring charging sub-base 703 and the wireless magnetic ring charging mother base 702 at the bottom of the drone body 6 have magnetic attraction, so that the user only needs to operate the drone. After the main body 6 is roughly aligned, the magnetic force of the wireless magnetic ring charging socket 702 and the wireless magnetic ring charging sub-holder 703 can adsorb and position the drone main body 6 when it is closed, so that the position of the frame can be accurately caught by the hook 502, and the drone main body 6 can be wirelessly charged. When charging is completed, the first cylinder 701 is started to shrink the position of the wireless magnetic ring charging socket 702, and the wireless magnetic ring charging socket 702 is powered off. At this time, the drone main body 6 can be controlled to take off without being affected by the magnetic force of the wireless magnetic ring charging socket 702 and the wireless magnetic ring charging sub-holder 703.
