Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of unmanned aerial vehicles (UAVs), specifically relating to a connection device and an UAV. Background Technology
[0002] In the current field of collaborative operations between drones and ground vehicles, the connection technology between drones and vehicles is crucial. Existing connection technologies for drones and vehicles (such as vehicles) mainly include mechanical latches, electromagnetic adsorption, elastic pins, and manual fixing, but these connection methods have many shortcomings. Mechanical latches connect drones and vehicles, but this method has limitations; unlocking requires manual operation, which is inefficient. Electromagnetic adsorption relies on electricity to maintain adhesion, posing a safety hazard once power is lost, and cannot guarantee the stability and security of the connection. It is also greatly affected by environmental factors; in metallic environments or areas with strong electromagnetic interference, the magnetic attraction effect is unstable, making reliable connection impossible and limiting its application scenarios. Elastic pins have complex structures and are easily affected by external forces in actual use, leading to loosening of the connection and affecting the reliability of operations. Simple binding methods are not only cumbersome and time-consuming, but also difficult to guarantee connection strength, easily leading to loosening during drone flight, posing a threat to operational safety. Therefore, there is an urgent need for an efficient and reliable connection device. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] In a first aspect, a connecting device is provided, comprising a lock head structure and a lock cylinder structure. The lock head structure includes a fixed bracket, a power drive component, and a rotary plug. The lock cylinder structure can be mounted on a second device to be connected. The fixed bracket is used to mount the lock head structure on a first device to be connected. The rotary plug is rotatably connected to the fixed bracket. The lock cylinder structure includes a main body and a cover plate. The main body is provided with an inwardly recessed groove. The cover plate is disposed on the top of the main body and is used to seal the groove. The cover plate is provided with a strip-shaped hole communicating with the groove. The strip-shaped hole can accommodate the rotary plug entering and exiting the groove at a first rotation angle and can restrict the rotary plug from leaving the groove at a second rotation angle. The power drive component is mounted on the fixed bracket, and its output end is connected to the tail of the rotary plug. When the head of the rotary plug is fully inserted into the groove, the tail of the rotary plug can rotate within the strip-shaped hole.
[0006] Optionally, the cover plate has two baffles on its surface facing away from the lock head structure; the two baffles are located at both ends of the length direction of the strip hole, the extension direction of the baffles is the width direction of the strip hole, and the strip hole passes through the baffles.
[0007] Optionally, the cover plate, the main body, and the baffle are integrally formed; the main body is a cylindrical structure.
[0008] Optionally, the rotary plug is arrow-shaped or T-shaped; the head of the rotary plug is a large-diameter end and its thickness is less than the width of the strip hole.

[0024] Example 1
[0025] like Figures 1-6 As shown, a connecting device includes a lock head structure 1 and a lock cylinder structure 2. The lock head structure 1 includes a fixed bracket 11, a power drive component 12, and a rotary plug 13. The lock cylinder structure 2 can be installed on a second device to be connected. The fixed bracket 11 is used to install the lock head structure 1 on a first device to be connected. The lock head structure 1 and the lock cylinder structure 2 are used together to connect the first device to be connected and the second device to be connected.
[0026] like Figure 4 and Figure 5As shown, the rotary plug 13 is rotatably connected to the fixed bracket 11; the lock cylinder structure 2 includes a main body 21 and a cover plate 22; the main body 21 is provided with an inwardly recessed groove 211, and the cover plate 22 is provided on the top of the main body 21 and is used to seal the groove 211; the cover plate 22 is provided with a strip hole 221 communicating with the groove 211; the strip hole 221 extends through the cover plate 22 vertically, and the length dimension of the strip hole 221 is greater than the width dimension. The strip hole 221 can accommodate the rotary plug 13 to enter and exit the groove 211 in a state of first rotation angle, and can restrict the rotary plug 13 to leave the groove 211 in a state of second rotation angle. The first rotation angle and the second rotation angle refer to the rotation angle of the rotary plug 13 relative to the central axis of the fixed bracket 11 or the rotation angle relative to the central axis of the lock cylinder structure 2. The included angle of the first rotation angle and the second rotation angle can be any angle between 0-180° (excluding the endpoints), that is, 30°, 45°, 60°, 90° or any other angle.
[0027] The power drive unit 12 is mounted on the fixed bracket 11, and its output end is connected to the tail of the rotary plug 13. When the head of the rotary plug 13 is fully inserted into the groove 211, the tail of the rotary plug 13 can rotate within the slot 221. The power drive unit 12 is typically a stepper motor capable of rotating in both directions. After the head of the rotary plug 13 enters the groove 211, the stepper motor drives the rotary plug 13 to rotate 90°. At this time, the slot 221 restricts the rotary plug 13 from disengaging from the groove 211. The first device to be connected and the second device to be connected can approach each other under the action of external force or their own action. After they approach each other, the rotary plug 13 is allowed to vertically enter the groove 211 from the state of the first rotation angle. When the stepper motor stops driving, the rotary plug 13 does not rotate relative to the first device to be connected.
[0028] In this embodiment, two baffles 23 are provided on the surface of the cover plate 22 facing away from the lock head structure 1. The two baffles 23 are located at both ends of the length direction of the strip hole 221, and the extension direction of the baffles 23 is the width direction of the strip hole 221. The strip hole 221 passes through the baffles 23, that is, the strip hole 221 spans the two baffles 23. When the rotating plug 13 is inserted into the groove 211 and is in the state of the second rotation angle, the two baffles 23 are respectively located on both sides of the rotating plug 13. The baffles 23 do not affect the rotating plug 13 entering and exiting the groove 211, and when the rotating plug 13 is limited inside the cover plate 22, they can limit the rotation of the rotating plug 13, so as to prevent the lock cylinder structure 2 from rotating relative to the rotating plug 13 due to external force or misoperation, thereby allowing the rotating plug 13 to return to the first rotation angle or rotate to the third rotation angle, further ensuring the stability and security of the connection of the connecting device. When the lock head structure 1 needs to disengage from the lock cylinder structure 2, the rotating plug 13 descends to below the baffle 23. At this time, the stepper motor rotates in the opposite direction to make the rotating plug 13 rotate back to the first rotation angle state, and then rises from the strip hole 221 to disengage from the lock cylinder structure 2.
[0029] In this embodiment, the cover plate 22, the main body 21 and the baffle 23 are integrally formed; the main body 21 is a cylindrical structure and the lock core structure 2 can be made of titanium alloy.
[0030] like Figure 2 and Figure 5 , Figure 6 As shown, in this embodiment, the rotating plug 13 is arrow-shaped or T-shaped; the head of the rotating plug 13 is the large-diameter end and its thickness is less than the width of the strip hole 221, that is, the first rotation angle state of the rotating plug 13 is that the thickness direction of the large-diameter end of the rotating plug 13 is consistent with the width direction of the strip hole 221.
[0031] In some other embodiments, the rotary plug 13 is rotatably connected to the fixed bracket 11 via a connecting frame 14. The connecting frame 14 includes a first frame 141 and a T-shaped block 142. The bottom of the first frame 141 is connected to the tail of the rotary plug 13. The small-diameter end of the T-shaped block 142 passes through the bracket 11 and is connected to the top of the first frame 141, and is rotatably connected to the fixed bracket 11. That is, the T-shaped block 142 and the top of the first frame 141 form an I-shaped structure, which can prevent the rotary plug 13 from falling off the fixed bracket 11 and allow the rotary plug 13 to rotate relative to the fixed bracket 11. The output shaft of the power drive 12 is connected to the large-diameter end of the T-shaped block 142.
[0032] In this embodiment, the fixed bracket 11 includes a first connecting plate 111, a second connecting plate 112, and support rods 113; the first connecting plate 111 and the second connecting plate 112 are parallel vertically and connected by a plurality of support rods 113; the cross-sectional area of the first connecting plate 111 is larger than that of the second connecting plate 112, and the first connecting plate 111 is used for detachable connection of the first device to be connected; the power drive component 12 is mounted on the second connecting plate 112, and the fixed bracket 11 can be made of titanium alloy or other lightweight alloy materials, as long as it is lightweight enough while ensuring strength.
[0033] The lock cylinder structure 2 is provided with a second frame 24 at the end opposite to the lock head structure 1. The second frame 24 is used for detachable connection of the second device to be connected.
[0034] Example 2
[0035] A drone includes a drone body and a carrier; the drone body and the carrier are connected by a connecting device as described in any one of Embodiment 1, that is, the locking head structure 1 is installed on the drone body and the locking cylinder structure 2 is installed on the carrier, or the locking head structure 1 is installed on the carrier and the locking cylinder structure 2 is installed on the drone body.
