Description

Technical Field

[0001] The invention relates to the field of unmanned aerial vehicles, and in particular to an automatic offline connection component and a tethered unmanned aerial vehicle system. Background Art

[0002] Tethered drones are a type of drone that is developing rapidly nowadays. Powered by ground tethered cables, drones can work uninterruptedly for 24 hours, solving the problem of short battery life for current drones. The flight and control of tethered drones require high voltage and high current loads, so most tethered drones do not have their own power supply units. They are generally connected to the ground power supply system through one or more cables, and rely on the ground power supply system to provide them with the power required for endurance. Therefore, tethered drones always drag cables during flight. When evacuating the drone, the tethered drone needs to be landed and then disconnected from the ground equipment. This operation cannot achieve the rapid evacuation of ground equipment. Summary of the invention

[0003] A first object of the present invention is to provide an automatic disconnecting connection assembly for realizing rapid evacuation of ground equipment.

[0004] A second object of the present invention is to provide a tethered drone system comprising the above-mentioned automatic disconnection connection component.

[0005] In order to achieve the above-mentioned first purpose, the automatic offline connection component provided by the present invention includes a first connection component and a second connection component, the first connection component includes a first shell, a driving device, a driving block and at least one first electrical connection head, the first shell is provided with a first clamping portion, the driving device and at least one of the first electrical connection heads are respectively arranged on the first shell; the second connection component includes a central carrier, a first slider, a first spring, a second clamping portion and at least one second electrical connection head, a movable chamber is provided in the central carrier, the first slider and the first spring are respectively arranged in the movable chamber, the first spring abuts between the first slider and the central carrier, the driving device drives the driving block to move toward the first slider, the driving block drives the first slider to move along the moving direction of the driving block, the second clamping portion is arranged on the periphery of the movable chamber, the first slider drives the second clamping portion to move away from the first clamping portion, and the central carrier moves away from the first shell along the moving direction of the driving block; at least one first electrical connection head is connected one-to-one with at least one second electrical connection head.

[0006] It can be seen from the above scheme that before the tethered drone takes off, the first engaging portion in the first connecting component is matched and connected with the second engaging portion in the second connecting component, so that the first electrical connector is connected with the second electrical connector, and the electrical transmission or signal transmission between the ground power supply system and the tethered drone is completed. When it is necessary to disconnect the tethered cable of the tethered drone in flight, the driving device drives the driving block to move toward the first slider, and the movement of the first slider drives the second engaging portion to move away from the first engaging portion, so that the connection between the first connecting component and the second connecting component is disconnected. When the driving block continues to drive the first slider to move, the second connecting component is completely disconnected from the second connecting component; in the disconnection process, the movement of the driving block realizes the linkage through the first slider to drive the second engaging portion to disconnect from the second engaging portion, and the continued movement of the driving block causes the second connecting component to completely disconnect from the first connecting component along the moving direction of the driving block, thereby avoiding the situation where the second connecting component cannot be quickly disconnected from the first connecting component due to the friction at the connection between the first connecting component and the second connecting component, thereby achieving automatic disconnection and effectively improving work efficiency.

[0007] A further solution is that the second connecting component includes a second spring and a connecting piece, the second spring abuts between the second clamping portion and the central carrier; a first through groove is provided on the side wall of the movable chamber, the connecting piece is provided in the first through groove, the first end of the connecting piece can be located in the movable chamber, the second end of the connecting piece is connected to the second clamping portion, a hinged portion is provided on the connecting piece, the hinged portion is provided between the first end of the connecting piece and the second end of the connecting piece, and the hinged portion is hinged to the central carrier.

[0008] It can be seen that the connecting piece is arranged between the second engaging part and the first slider. Through the setting of the connecting piece, the first slider, the connecting piece and the second engaging part form a connecting assembly, through which the second engaging part can be better moved along the elastic force direction of the second spring, so that the engagement or disengagement between the second engaging part and the first engaging part is more precise and rapid.

[0009] A further solution is that a protruding block is provided on the central carrier, a through slot is provided on the second engaging portion, the protruding block is located in the second through slot, the second spring is located in the second through slot, and the second spring abuts between the second engaging portion and the protruding block.

[0010] It can be seen that under the driving action of the first slider, the second engaging part moves away from the first engaging part to realize the disconnection between the second engaging part and the first engaging part, and the setting of the protruding block can serve as an installation carrier of the second spring. At the same time, since the protruding block is set in the through groove of the second engaging part, the protruding block can limit the movement displacement of the moving second engaging part, and the second spring is set in the through groove of the second engaging part. The movement of the second engaging part away from the first engaging part squeezes the second spring. The setting of the second through groove can limit the squeezing direction of the second spring to avoid the squeezing deviation of the second spring, which makes it difficult to drive the second engaging part to move in the desired direction subsequently.

[0011] A further solution is that the second end of the linkage member is arranged between the protruding block and the moving chamber.

[0012] It can be seen that the linking member is hinged to the central carrier. When the first slider drives the linking member to rotate, the second end of the linking member moves between the protruding block and the movable chamber, so as to limit the rotation range of the linking member.

[0013] A further solution is that the central carrier comprises a limiting plate, which is arranged on the outer periphery of the moving chamber along the circumference of the moving chamber, and the first end of the linkage member can abut against the limiting plate.

[0014] It can be seen that when the linking member rotates, the limiting plate limits the first end of the linking member, further limiting the rotation amplitude of the linking member, thereby controlling the movement displacement of the second engaging portion.

[0015] A further solution is that the center carrier includes a first center plate and a second center plate, the first center plate is arranged along the circumference of the moving chamber, a groove is arranged on the first center plate, and the second clamping part is correspondingly arranged in the groove; the second center plate is pressed onto the second clamping part.

[0016] It can be seen that the groove on the first center plate limits the second clamping part in its moving direction, and the second center plate presses the second clamping part to further limit the second clamping part in another direction, so that the moving direction of the second clamping part is more accurate.

[0017] A further solution is that the driving block is a nut screw, the first connecting assembly includes a second slider, the second slider is connected to the nut screw, the second slider is sleeved on the outer periphery of the nut screw, the second slider can move along the axial direction of the nut screw, and the second slider drives the first slider to move.

[0018] It can be seen that the driving block is a nut screw, and the driving device drives the nut in the nut screw to move along the axial direction of the screw. As the nut and the second slider move, the second slider moves along the axial direction of the screw, so that the second slider drives the first slider to move. The nut screw is used as the driving block, and the screw can be used as a guide rod to guide the movement of the second slider.

[0019] A further solution is that the first shell includes an annular side plate, the driving block is located in the inner circle of the annular side plate, the first clamping portion is a clamping groove, and the first clamping portion is located on the inner wall of the annular side plate; the second clamping portion is a push block, and the number of second clamping portions is four. The four push blocks are radially arranged with the moving chamber as the center, and the distance between every two adjacent push blocks is equal along the circumference of the moving chamber.

[0020] It can be seen that the connection between the first connecting component and the second connecting component is completed by using the locking structure of the card slot and the push block, and the off-line is better achieved by driving the push block to move by the slider, and the four push blocks are arranged radially with the moving chamber as the center, so that the push blocks driven by a first slider can move at the same time, making the layout of the internal components of the off-line component structure more reasonable.

[0021] A further solution is that the second connecting component includes a second shell, the second shell is annular, the central carrier is arranged in the second shell, the push block can pass through the second shell, an anti-foolproof protrusion block is arranged on the outer wall of the second shell, an anti-foolproof groove is arranged on the inner wall of the first shell, the anti-foolproof protrusion block is arranged in the anti-foolproof groove, and the anti-foolproof groove extends along the moving direction of the driving block.

[0022] It can be seen that the fool-proof structure formed by connecting the fool-proof protrusion block and the fool-proof groove can enable the first electrical connector and the second electrical connector to be accurately connected.

[0023] To achieve the above-mentioned second purpose, the tethered drone system provided by the present invention includes a drone, an automatic offline connection component as mentioned above, and a ground power supply component, the drone is connected to the first electrical connector via a first tethered line, and the ground power supply component is connected to the second electrical connector via a second tethered line.

[0024] It can be seen from the above scheme that the drone is connected to the first electrical connector in the first connecting component through the first tethering line, and the ground power supply component is connected to the second electrical connector in the second connecting component through the second tethering line. Through the connection and disconnection between the first connecting component and the second connecting component, quick disconnection and connection are achieved.

[0051] Before the tethered drone takes off, it is necessary to connect the first connection component 1 with the second connection component 2 to achieve the connection between the first electrical connector 14 and the second electrical connector 24. The second housing 25 is manually driven to move toward the first housing 11, driving the push block 4 to move toward the first moving chamber 213, and the second spring 42 is compressed until the push block 4 enters the card slot 3. The push block 4 moves toward the card slot 3 under the elastic force of the second spring 42, completing the engagement connection between the push block 4 and the card slot 3, thereby achieving the connection between the first electrical connector 14 and the second electrical connector 24, and completing the electrical transmission or signal transmission between the ground power supply system and the tethered drone.

[0052] When it is necessary to disconnect the tethered cable of the tethered UAV in flight, the driving device can drive it by using the battery carried by the UAV as power, and the driving device 12 drives the screw rod 132 to rotate, and the nut 131 on the screw rod 132 rotates to drive the second slider 15 to move toward the first slider 22. When the second slider 15 abuts against the first slider 22, the movement of the second slider 15 drives the first slider 22 to move along the axial direction of the screw rod 132, the first spring 23 is compressed, and the limiting rod 217 also moves along the moving direction of the first slider 22, and the axial direction of the limiting rod 217 is parallel to the axial direction of the screw rod 132. The movement of the first slider 22 drives the first end of the linkage 5 to rotate, so that the second end of the linkage 5 moves toward the first moving chamber 213, so that the push block 4 moves away from the card slot 3, thereby realizing the disconnection of the clamping connection between the push block 4 and the card slot 3. The second slider 15 continues to drive the first slider 22 to move axially along the screw rod 132, driving the second housing 25 that is disconnected from the first housing 11 to continue to move axially along the screw rod 132, so that the second housing 25 is quickly detached from the first housing 11, achieving rapid disconnection and effectively improving work efficiency.

The outer wall of the first shell 11 and the outer wall of the second shell are respectively threaded, and the threads on the first shell 11 and the second shell 25 can be used to connect the mooring lines.

[0054] In this embodiment, the linkage structure formed by the first slider 22, the linkage member 5 and the push block 4 is used to achieve the disconnection between the first clamping part and the second clamping part. As another embodiment, the first clamping part and the second clamping part can be support blocks respectively, and the second clamping part is hinged to the central carrier 21. When the first shell 11 is connected to the second shell, the first clamping part supports the second clamping part.
