Description

TECHNICAL FIELD

[0001] The present application relates to the field of unmanned aerial vehicle nests, in particular to a double rocker arm nest upper cover electric opening and closing mechanism. BACKGROUND

[0002] It has become a trend to use unmanned aerial vehicles (UAVs) to complete the inspection of power lines, and UAVs are gradually replacing manual inspection. A UAV nest serving the UAV is a platform that enables the automatic take-off and landing of the UAV, or a "safe house". The UAV nest can be installed in the wild, and a person can remotely control the UAV to automatically fly out of the nest and land. The UAV nest can also automatically charge and replace the battery of the UAV. In addition, the UAV nest can sense external weather and is waterproof, windproof, dustproof and theftproof.

[0003] The existing UAV nests mainly have flat opening and drum type opening. The flat opening type nest requires a track and a lifting mechanism, and the entire system is large and complex. The upper cover of the drum type nest rotates around the shaft, and the space utilization rate is low. The upper cover cannot be installed with a weather station and other equipment. For example, a Chinese invention patent with application number 202110771646.X discloses an automatic recovery and charging nest for vertical take-off and landing fixed-wing UAV, which comprises a cabin body and a openable top cover installed on the top of the cabin body. An inner cabin is also installed in the cabin body, and the height of the inner cabin is the same as that of the cabin body. A rotating mechanism is arranged inside the inner cabin. A clamping and centering device is installed on the top of the inner cabin, and a locking and charging device is also installed on the clamping and centering device. The locking and charging device comprises a base connected with the clamping and centering device and a pneumatic hydraulic clamp connected with the base for charging. The nest of the invention can realize automatic folding and unfolding, automatic charging, unattended operation and data uploading. Remote real-time monitoring can be realized, and the automatic mode can be released for manual remote operation. The nest can also be compatible with vertical take-off and landing UAVs and multi-rotor UAVs.

[0061] In order to make the skilled in the art better understand the technical solutions of the application, the application will be further described in detail below with reference to the drawings.

[0062] The application provides a kind of intelligent control system, including Figures 1-24The electric opening and closing mechanism of the double rocker arm nest upper cover shown in the figure comprises two U-shaped installation base plates 5, which are symmetrically installed on the top of the nest body 1. The U-shaped installation base plate 5 is provided with an installation hole, and it is detachably installed on the nest body 1 through a screw. The top cover 2 is movably connected on both sides of the top of the nest body 1. When the top cover 2 moves along a curved trajectory, the top cover 2 always maintains a horizontal state. The top of the nest body 1 is provided with an inner cabin 3 and a locking charging part 4, which are used for landing and charging of the unmanned aerial vehicle respectively. The basic functions of the nest are realized by referring to the prior art. The driving shaft 6 is rotatably connected between the two sides of the U-shaped installation base plate 5 through a bearing. The two ends of the driving shaft 6 extend out of the U-shaped installation base plate 5 and are drivingly connected with the first rocker arm 7. The two side walls of the U-shaped installation base plate 5 and the driving shaft 6 are diagonally rotatably connected with the driven shaft 8 through a bearing. The position of the bearing is limited by a bearing retainer. The bearing is regularly oiled to ensure the lubricity between structures and ensure smooth and reliable rotation. The two ends of the driven shaft 8 extend out of the U-shaped installation base plate 5 and are drivingly connected with the second rocker arm 9. As shown in the drawing, the first rocker arm 7 is arranged on the top of the second rocker arm 9 on the same side. The first rocker arm 7 and the second rocker arm 9 on the same side are jointly connected with the upper cover connecting plate 10 at the end away from the U-shaped installation base plate 5. The first rocker arm 7, the second rocker arm 9 and the upper cover connecting plate 10 are all made of aluminum alloy or 45 steel to meet the requirements of balance weight reduction and strength guarantee. The first rocker arm 7 and the second rocker arm 9 are hingedly arranged at two diagonal positions with the upper cover connecting plate 10 through the short shaft 11 (as shown in the drawing). The upper cover connecting plate 10 is detachably installed with the top cover 2 (such as fixed by a screw). The two ends of the first rocker arm 7 and the second rocker arm 9 are movable, and the first rocker arm 7 and the second rocker arm 9 are hingedly connected with the two short shafts 11. The first rocker arm 7 and the second rocker arm 9 are respectively fixed with the driving shaft 6 and the driven shaft 8, and the driving shaft 6 and the driven shaft 8 are rotatable with the U-shaped installation base plate 5, so as to realize the movement of the top cover 2 according to the trajectory. During the movement of the top cover 2, only the position is changed, not the angle. During the rotation of the rocker arm, there is no dead point, the rotation is smooth, and the attitude of the top cover 2 will not change suddenly.

The top of the nest body 1 is rotatably connected with the bidirectional screw rod 13 on both sides. The driving motor I 14 is fixedly connected on both sides of one end of the top of the nest body 1. The output shafts of the two driving motors I 14 are drivingly connected with the two bidirectional screw rods 13. The two adjusting sleeves 12 arranged on the same side are symmetrically distributed on the outside of the bidirectional screw rod 13. The adjusting sleeve 12 is threadedly connected with the bidirectional screw rod 13. The two driving motors I 14 are controlled to work synchronously, so that the adjusting sleeves 12 on both sides of the bidirectional screw rod 13 move relatively, and the distance between the two top covers 2 can be adjusted.

[0064] Two adjusting gears 15 are installed on the same side end of the two driving shaft rods 6, and a driving adaptation assembly 16 is movably connected below the two adjusting gears 15, which is used to cooperate with the two adjusting gears 15 and drive the adjusting gears 15 on both sides to reverse twist, so that the two top covers 2 are synchronized to open and close, and the top of the nest can be quickly opened or closed.

[0065] The driving adaptation assembly 16 comprises a lifting part, an L-shaped frame 162 and a driving motor II 163. The lifting part is fixed on the side wall of the nest body 1 and is used to adjust the height of the L-shaped frame 162. The two ends and the corner parts of the L-shaped frame 162 are rotatably connected with synchronous reversing gears 164. The two synchronous reversing gears 164 adjacent to each other are in meshing transmission, and the two synchronous reversing gears 164 at the top are at the same horizontal height. The driving motor II 163 is fixed on the L-shaped frame 162, and the output shaft of the driving motor II 163 is in transmission connection with one of the synchronous reversing gears 164 through a belt. When the driving adaptation assembly 16 works with the two adjusting gears 15, the two synchronous reversing gears 164 at the top are adjusted to mesh with the two adjusting gears 15 on both sides respectively, and then the driving motor II 163 is controlled to work, so that the output shaft of the driving motor II 163 drives one of the synchronous reversing gears 164 through the belt, and further drives the three synchronous reversing gears 164 to rotate at the same time, and the two synchronous reversing gears 164 at the top rotate in opposite directions, so that the two adjusting gears 15 on both sides rotate in opposite directions, so as to achieve the purpose of closing and unfolding the two top covers 2.

[0066] The driving cooperation of the driving adaptation assembly 16, the bidirectional screw rod 13 and the adjusting sleeve 12 enables the two top covers 2 to not only realize the effect of arc-shaped unfolding or closing, but also adjust the distance between the two top covers 2, so that the running track can meet the actual use requirements.

[0067] The inner walls of the L-shaped mounting base plate 5 are respectively provided with a travel switch I 17 and a travel switch II 18. The two driven shaft rods 8 are respectively provided with a first eccentric shaft plate 19 and a second eccentric shaft plate 20 at the inner side end positions of the L-shaped mounting base plate 5. The end parts of the first eccentric shaft plate 19 and the second eccentric shaft plate 20 are respectively matched with the triggering points of the travel switch I 17 and the travel switch II 18. The angle between the center line of the first eccentric shaft plate 19 to the end part and the center line of the second eccentric shaft plate 20 to the end part is set to 90°, and the first eccentric shaft plate 19 and the second eccentric shaft plate 20 are vertically distributed and cooperate with the travel switch I 17 and the travel switch II 18, and correspond to the closed state and the open state of the nest, i.e. the closing state and the fully unfolded state of the two top covers 2.

[0068] The two sides of the L-shaped mounting base plate 5 are also provided with a jacking limiting assembly 21, which is used to jack the first rocker arm 7 and the second rocker arm 9 after the adjusting gear 15 is adjusted, so as to ensure the stability of the top cover 2 in the stop state.

[0069] The opening and closing mechanism is installed on the nest body 1, when the opening and closing mechanism is in the upper limit position, the two side covers 2 are just completely closed; when the opening and closing mechanism is in the lower limit position, the two side covers 2 reach the maximum opening range, and the unmanned aerial vehicle can perform take-off and landing operation; when the opening and closing mechanism is between the upper limit position and the lower limit position, the height of the two side covers 2 can be adjusted according to actual needs, and the distance between the two side covers 2 is further adjusted to form a working platform for use, and cooperates with the extended bearing plate 202 to form an expanded platform, which is convenient for outdoor use. The sealing property of the extended bearing plate 202 is high, which can protect the electrical components on the top of the nest body 1 and reduce the influence of water, dust and other factors;

[0073] When the top pressing and limiting assembly 21 works, the gas pump 211 is started, the folded air bag body 212 is inflated, the metal grommet 214 and the butterfly spring 215 are pushed close to the first rocker arm 7 or the second rocker arm 9, and continuous pressing is performed until the first rocker arm 7 and the second rocker arm 9 are hindered by external force and are not easy to rotate. In the specific structure, a side internal pressure sensor can be matched in the folded air bag body 212, a pressure value range is set, and inflation is stopped when the limit value is reached; when it is necessary to further adjust the angle, the folded air bag body 212 is deflated, the internal pressure is reduced, and the external force of the first rocker arm 7 or the second rocker arm 9 is insufficient to limit it under the action of the butterfly spring 215, that is, the angle can be continuously adjusted.
