Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and mainly relates to an unmanned aerial vehicle fixing and resetting device for a machine nest and an unmanned aerial vehicle machine nest. Background Art

[0002] UAVs are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. With the development of wireless communication technology, aerial remote sensing mapping technology, GPS navigation and positioning technology, and automatic control technology, UAVs have developed rapidly and are widely used in power inspection, environmental monitoring, post-disaster rescue, topographic survey and other fields.

[0003] During the operation of drones, the battery capacity is limited, and the endurance of drones is greatly restricted, making it impossible to achieve long-distance flight and ultra-long standby flight. How to effectively replace and recharge drone batteries in a timely manner using drone nests has become a problem that must be faced in the development and application of drones.

[0004] Based on the above problems, the invention patent document with the authorization announcement number CN108438245B discloses a drawer-type drone nest, including a cavity with an opening and a door panel that can block the opening, and also includes a driving mechanism for driving the apron and the drone to enter and exit the cavity through the opening. The apron is set horizontally, and the cavity and the apron form a drawer shape. When the drone needs to dock, the door panel opens the opening, and the driving mechanism drives the apron to slide out of the cavity, and the drone docks smoothly on the apron. Then the driving mechanism controls the apron and the drone to retract into the cavity as a whole, and the door panel blocks the opening again; similarly, when the drone needs to be released, the door panel opens the cavity, and the driving mechanism controls the apron and the drone to slide out of the cavity as a whole. After the drone takes off, the apron retracts into the cavity, and the door panel blocks the cavity again.

[0005] The above process of controlling the entry and exit of the drone and the blocking of the door panel is relatively cumbersome, and requires two actions before and after to release or retract the drone, which prolongs the release time of the drone and is not conducive to quickly releasing or retracting the drone. Summary of the invention

[0006] The present invention provides a drone fixing and resetting device for a machine nest and a drone machine nest, so as to solve the problem in the prior art that the process of the drone entering and exiting the machine nest is complicated and not conducive to the rapid release or recovery of the drone.

[0007] To solve the above problems, the present invention adopts the following technical solutions: A device for fixing and resetting a drone for a machine nest, comprising a door panel for movably blocking the lower side of an opening of the machine nest and a helipad arranged on the machine nest, a fixing mechanism for fixing the drone is arranged on the helipad, a first rotating arm and a second rotating arm are hinged on both sides of the interior of the machine nest, mounting seats are hinged on the first rotating arm and the second rotating arm at the same time, the helipad is fixed on the two mounting seats, a linear drive component is hinged in the machine nest, the linear drive component is hinged to the second rotating arm, a connecting arm is hinged to the second rotating arm, the connecting arm is hinged to the door panel, the linear drive component drives the second rotating arm to rotate, so that the helipad is rotated into the machine nest, and drives the door panel to rotate so that it blocks the opening of the machine nest, or drives the door panel to rotate so that it opens the opening of the machine nest and allows the helipad to be rotated out of the machine nest.

[0008] The invention has the following beneficial effects: by setting the first rotating arm, the second rotating arm, the connecting arm and the corresponding mounting seat, when the UAV needs to be released, the apron can come out of the machine nest together with the door panel during the process of opening the door panel; at the same time, when the UAV needs to be recovered, the apron is reset into the machine nest, and the door panel can also be reset along with the apron to block the opening of the machine nest. The two actions are performed simultaneously, which reduces the time for recovering or releasing the UAV and speeds up the release or recovery of the UAV.

[0009] Furthermore, the hinge axis of the linear drive member on the second rotating arm is coaxial with the hinge axis of the connecting arm on the second rotating arm.

[0010] Furthermore, the first rotating arm is provided with a plurality of hinge holes, and the plurality of hinge holes are used to adjust the hinge positions of the corresponding mounting seats on the first rotating arm.

[0011] The following beneficial effects are achieved: the plurality of hinge holes also have the effect of reducing weight, making the rotation of the apron easier, and also allowing the user to adjust the position of the mounting seat as required.

[0012] Furthermore, a weight-reducing hole is provided on the mounting seat.

[0013] The following beneficial effects are achieved: the weight-reducing holes can reduce the weight of the mounting seat itself, making the rotation of the apron easier.

[0014] Furthermore, wrapping plates are provided on both sides of the door panel, and grooves for engaging with corresponding wrapping plates are provided on both sides of the machine nest.

[0015] The invention has the following beneficial effects: in this way, the effect of sealing the opening of the machine nest can be better.

[0016] Furthermore, a sealing installation groove is provided at the opening of the machine nest, and a sealing ring is provided in the sealing installation groove. The sealing ring is used to fit with the door panel so that the door panel seals the opening of the machine nest.

[0017] The invention has the following beneficial effects: a sealing ring is installed in the sealing installation groove, and when the door panel blocks the opening of the machine nest, the door panel will squeeze the sealing ring, causing the sealing ring to produce elastic deformation, thereby sealing the opening of the machine nest.

[0018] Furthermore, both sides of the first rotating arm and the second rotating arm are provided with flanges, and the folding direction of the flanges is perpendicular to the extension direction of the corresponding first rotating arm or the second rotating arm.

[0019] The following beneficial effects are achieved: such a flange can enhance the strength of the corresponding first rotating arm or second rotating arm, making it difficult for the first rotating arm or second rotating arm to bend, so that the first rotating arm and the second rotating arm can support a heavier drone.

[0020] Furthermore, a first proximity switch is provided on the mounting seat, and when the apron is rotated out of the nest and reaches a set position, the first proximity switch and the first rotating arm are in conflict.

[0021] The invention has the following beneficial effects: when the first rotating arm contacts the first proximity switch, it indicates that the apron is rotated out of the nest and reaches the set position, and the linear driving member no longer drives the second rotating arm to rotate.

[0022] Furthermore, a second proximity switch is provided inside the machine nest, and when the door panel blocks the opening of the machine nest, the second proximity switch conflicts with the second rotating arm.

[0023] The following beneficial effects are achieved: the second rotating arm contacts the second proximity switch, indicating that the door panel has completely blocked the opening of the machine nest, and the linear drive member no longer drives the second rotating arm to rotate.

[0024] A drone nest comprises any one of the drone fixing and resetting devices for the nest.

[0025] The invention has the following beneficial effects: by setting the first rotating arm, the second rotating arm, the connecting arm and the corresponding mounting seat, when the UAV needs to be released, the apron can come out of the machine nest together with the door panel during the process of opening the door panel; at the same time, when the UAV needs to be recovered, the apron is reset into the machine nest, and the door panel can also be reset along with the apron to block the opening of the machine nest. The two actions are performed simultaneously, which reduces the time for recovering or releasing the UAV and speeds up the release or recovery of the UAV. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0030] Embodiment of the UAV fixing and resetting device like Figure 1 , Figure 4 , Figure 6As shown, the nest 1 can be used as a harbor for drones to dock after flying and patrolling. The nest 1 has an inner cavity, and an opening connected to the inner cavity is also provided on the nest 1. The inner cavity of the nest 1 is used to store drones, and the drones enter and exit the inner cavity of the nest 1 through the opening. A drone fixing and resetting device for the nest in this embodiment is used to take the drone out of the inner cavity of the nest 1 or to relocate the drone to the inner cavity of the nest 1. The drone in the inner cavity of the nest 1 can be charged, or the battery can be directly replaced, or other work can be performed.

[0031] The drone fixing and resetting device for the nest 1 in this embodiment includes a door panel 8 and a helipad 2 provided on the nest 1. The door panel 8 is used to block or open the opening. The door panel 8 is hinged to the lower side of the opening of the nest 1 through hinges, so that when the door panel 8 is opened, the upper side of the opening is opened first. A fixing mechanism 3 for fixing the drone is provided on the helipad 2. The fixing mechanism 3 can fix the drone on the helipad 2 and restrict the movement of the drone on the helipad 2, so that the drone can be prevented from falling from the helipad 2 during the process of entering and exiting the nest 1.

[0032] like Figure 2 As shown, the first rotating arm 4 and the second rotating arm 5 are hinged on both sides of the inner cavity of the machine nest 1, that is, the first rotating arm 4 and the second rotating arm 5 are provided on the left side of the inner cavity of the machine nest 1, and the first rotating arm 4 and the second rotating arm 5 are provided on the right side of the inner cavity of the machine nest 1. The hinge positions of the first rotating arm 4 and the second rotating arm 5 are spaced apart, and the hinge position of the first rotating arm 4 is close to the opening position, and the hinge position of the second rotating arm 5 is located at the rear side of the hinge position of the first rotating arm 4. The first rotating arm 4 and the second rotating arm 5 on the same side are hinged with mounting seats 6 at the same time, that is, the inner cavity of the machine nest 1 has two mounting seats 6, and the apron 2 is fixed on the two mounting seats 6, so that when the first rotating arm 4 and the second rotating arm 5 rotate around the corresponding hinge axis, the apron 2 can also move.

[0033] In this embodiment, the lengths of the first rotating arm 4 and the second rotating arm 5 are consistent, and the distance between the hinged positions of the first rotating arm 4 and the second rotating arm 5 on the machine nest 1 is the same as the distance between the hinged positions of the first rotating arm 4 and the second rotating arm 5 on the mounting seat 6. At the same time, there is an angle between the line between the hinged positions of the first rotating arm 4 and the second rotating arm 5 on the machine nest 1 and the horizontal plane, and the apron 2 arranged on the mounting seat 6 is in a horizontal state. In this way, during the process of the apron 2 entering and exiting the machine nest 1, the apron 2 will be in a horizontal state.

[0034] In other embodiments, the lengths of the first rotating arm 4 and the second rotating arm 5 are consistent, and the distance between the hinged positions of the first rotating arm 4 and the second rotating arm 5 on the machine nest 1 is the same as the distance between the hinged positions of the first rotating arm 4 and the second rotating arm 5 on the mounting seat 6. At the same time, the hinge axes of the first rotating arm 4 and the second rotating arm 5 on the machine nest 1 are in the same horizontal plane, and the hinge axes of the first rotating arm 4 and the second rotating arm 5 on the mounting seat 6 are in the same horizontal plane. The apron 2 arranged on the mounting seat 6 is in a horizontal state, so that the apron 2 will be in a horizontal state during the process of the apron 2 entering and exiting the machine nest 1.

[0035] like Figure 2 As shown, a linear drive member 7 is hinged in the nest 1, and the linear drive member 7 is hinged with the second rotating arm 5. The linear drive member 7 can drive the second rotating arm 5 to rotate around its hinge axis on the nest 1, and during the rotation of the second rotating arm 5, the linear drive member 7 will also rotate around its hinge axis on the nest 1. A connecting arm 9 is hinged on the second rotating arm 5, and the connecting arm 9 is hinged to the door panel 8. When it is necessary to recover the drone, the linear drive member 7 drives the second rotating arm 5 to rotate, and the first rotating arm 4 and the second rotating arm 5 will rotate into the nest 1 with the apron 2, and at the same time drive the door panel 8 to rotate, so that the door panel 8 blocks the opening of the nest 1 to seal the nest 1; or when it is necessary to release the drone, the linear drive member 7 drives the second rotating arm 5 to rotate, drives the door panel 8 to rotate, so that the door panel 8 opens the opening of the nest 1, no longer blocks the nest 1, and allows the apron 2 to rotate out of the nest 1 at the same time, so that the drone can fly away from the apron 2.

[0036] In this embodiment, the hinge axis of the linear drive member 7 on the second rotating arm 5 is coaxial with the hinge axis of the connecting arm 9 on the second rotating arm 5 .

[0037] The linear drive member 7 in this embodiment is a cylinder.

[0038] In other embodiments, the linear drive member 7 is a hydraulic cylinder or an electric push rod.

[0039] By providing the first rotating arm 4, the second rotating arm 5, the connecting arm 9 and the corresponding mounting seat 6, when the UAV needs to be released, the apron 2 can come out of the machine nest 1 together with the door panel 8 during the process of opening the door panel 8; at the same time, when the UAV needs to be recovered, the apron 2 is reset into the machine nest 1, and the door panel 8 can also be reset along with the apron 2 to block the opening of the machine nest 1. The two actions are performed simultaneously, which reduces the time for recovering or releasing the UAV and speeds up the release or recovery of the UAV.

[0040] like Figure 2 , Figure 3As shown, both sides of the first rotating arm 4 and the second rotating arm 5 are provided with flanges 12, and the folding direction of the flanges 12 is perpendicular to the extension direction of the corresponding first rotating arm 4 or second rotating arm 5. Such flanges 12 can enhance the strength of the corresponding first rotating arm 4 or second rotating arm 5, so that the first rotating arm 4 or second rotating arm 5 is not easy to bend during the process of driving the apron 2 to rotate, so that the first rotating arm 4 and the second rotating arm 5 can support the heavier UAV to enter and exit the machine nest 1. In this embodiment, the material of the first rotating arm 4 and the second rotating arm 5 can be aluminum alloy.

[0041] like Figure 4 , Figure 5 As shown, the first rotating arm 4 is provided with a plurality of hinge holes 14, which are of the same size and arranged along the extending direction of the first rotating arm 4. The plurality of hinge holes 14 are used to adjust the hinge positions of the corresponding mounting seats 6 on the first rotating arm 4. The plurality of hinge holes 14 also has the effect of reducing weight, making the rotation of the apron 2 easier, and also allows the user to adjust the position of the mounting seat 6 as needed.

[0042] In this embodiment, the number of hinge holes 14 can be determined according to the length of the first rotating arm 4 or actual needs during work, and this embodiment has no particular limitation on this.

[0043] like Figure 4 , Figure 5 As shown, the mounting base 6 is provided with a weight-reducing hole 15. The weight-reducing hole 15 can reduce the weight of the mounting base 6 itself, making the rotation of the apron 2 easier, reducing the energy consumption during rotation, and being more energy-saving.

[0044] like Figure 4 , Figure 6 As shown, wrapping plates 10 are provided on both sides of the door panel 8, and grooves 13 for engaging with the corresponding wrapping plates 10 are provided on both sides of the machine nest 1. When the door panel 8 blocks the opening of the machine nest 1, the wrapping plates 10 will engage with the grooves 13, which can better block the opening of the machine nest 1.

[0045] The upper side of the door panel 8 is provided with a locking assembly 11 that can be locked with the opening, and the locking assembly locks the door panel 8 on the machine nest 1. When the door panel 8 blocks the opening of the machine nest 1, the locking assembly 11 is locked with the machine nest 1 to close the opening of the machine nest 1.

[0046] like Figure 6 , Figure 7As shown, a folding plate 16 is provided at the opening of the machine nest 1, and the folding plate 16 and the machine nest 1 form a sealing installation groove 17 at the opening. A sealing ring is provided in the sealing installation groove 17, and the sealing ring is used to fit with the door panel 8 so that the door panel 8 can seal the opening of the machine nest 1. The sealing ring is installed in the sealing installation groove 17. When the door panel 8 blocks the opening of the machine nest 1, the door panel 8 will squeeze the sealing ring, causing the sealing ring to produce elastic deformation, thereby sealing the opening of the machine nest 1. In this way, even on rainy days, it is difficult for rainwater to enter the internal parts of the machine nest 1 to damage the components, thereby extending the life of the equipment; at the same time, it can also prevent some tiny animals from entering the machine nest 1.

[0047] A first proximity switch is provided on the mounting seat 6. When the apron 2 rotates out of the nest 1 and reaches a set position outside the nest 1, the first proximity switch and the first rotating arm 4 collide. When the first rotating arm 4 contacts the first proximity switch, it means that the apron 2 rotates out of the nest 1 and reaches the set position, and the linear driving member 7 no longer drives the second rotating arm 5 to rotate.

[0048] A second proximity switch is provided inside the machine nest 1. When the door panel 8 blocks the opening of the machine nest 1, the second proximity switch contacts the second rotating arm 5. The second rotating arm 5 contacts the second proximity switch, indicating that the door panel 8 has completely blocked the opening of the machine nest 1, and the linear drive member 7 no longer drives the second rotating arm 5 to rotate.

[0049] The working process of the present invention is as follows: When the drone needs to be released, the linear drive 7 drives the second rotating arm 5 to rotate, and the rotation of the second rotating arm 5 will drive the connecting arm 9 to move. The movement of the connecting arm 9 drives the door panel 8 to rotate around the hinge position, thereby opening the opening of the nest 1. During the rotation of the door panel 8, the rotation of the first rotating arm 4 and the second rotating arm 5 will drive the mounting seat 6 to rotate from the inside of the nest 1 to the outside of the nest 1, and the apron 2 located on the mounting seat 6 will also drive the drone to rotate to the set position outside the nest 1. When the apron 2 reaches the set position, the first contact switch will contact the first rotating arm 4, thereby triggering the first contact switch, and the first contact switch will feedback to the linear drive 7, and the linear drive 7 will no longer drive the second rotating arm 5 to rotate. After that, the fixing mechanism 3 releases the drone, and the drone can fly.

[0050] When the drone needs to be retrieved, the drone will dock on the apron 2 after completing the mission, and the fixing mechanism 3 will fix the drone on the apron 2 to prevent the drone from falling from the apron 2 during the rotation of the apron 2. After the drone is fixed, the linear drive 7 drives the second rotating arm 5 to rotate toward the inside of the nest 1, thereby driving the mounting seat 6 to rotate from the outside of the nest 1 to the inside of the nest 1, and the apron 2 located on the mounting seat 6 will also drive the drone to rotate to the set position in the inner cavity of the nest 1. In the process of the drone rotating toward the inside of the nest 1, the door panel 8 will also rotate around the position of the hinge, and the second rotating arm 5 will contact the second contact switch, thereby triggering the second contact switch, and the second contact switch will feedback to the linear drive 7, and the linear drive 7 will no longer drive the second rotating arm 5 to rotate. At this time, the door panel 8 completes the blocking of the opening of the nest 1, and the drone is also reset.

[0051] Embodiment of drone nest The machine nest in this embodiment includes the drone fixing and resetting device in the above embodiment. The machine nest 1 can be used as a harbor for the drone to dock after flying and patrolling. The machine nest 1 has an inner cavity, and an opening connected to the inner cavity is also provided on the machine nest 1. The inner cavity of the machine nest 1 is used to store the drone, and the drone enters and exits the inner cavity of the machine nest 1 through the opening.
