Description

Technical Field

[0001] The utility model belongs to the field of unmanned aerial vehicles, and in particular relates to a locking device which is convenient for unmanned aerial vehicles to carry a robot dog. Background Art

[0002] The joint operation of drone-mounted robot dogs refers to the use of the drone's maneuverability regardless of terrain and the robot dog's stability during long cruises to cooperate with each other. The drone drops the robot dog to the designated area to jointly complete the inspection task. This joint operation can perform more efficient and flexible tasks. In the prior art, drones are usually equipped with manipulators or cargo frames to transport robot dogs to the destination, and there is a problem of large connection module volume. In the solution of using a manipulator to clamp, the manipulator will fully clamp the left and right sides of the robot dog. The mechanical claw is not only large in size, but also has a large amplitude of movement each time it releases and clamps the robot dog. In the solution of using a cargo frame to accommodate the robot dog, after the drone arrives at the destination, the robot dog walks out or enters the cargo frame to complete the out-of-warehouse or in-warehouse action. The cargo frame itself is larger in size and heavy in weight, which will greatly reduce the carrying weight of the drone. Utility Model Content

[0003] The purpose of the utility model is to provide a locking device for a drone to carry a robot dog, which is small in size, stable in connection, and easy to use.

[0004] To achieve the above-mentioned purpose, the utility model provides a locking device for a drone to carry a robot dog, comprising a drone body and a robot dog body, wherein a clamping seat, a guide rod located in the clamping seat, a screw rod located in the clamping seat, a pair of claws penetrated by the guide rod and the screw rod, and a motor for driving the screw rod to rotate are arranged at the bottom of the drone body, the claws are plate-shaped, and raised ribs are arranged on the sides where the claws are close to each other; a splint is arranged on the upper side of the back of the robot dog, the splint is a T-shaped steel, the splint is arranged vertically, the middle area of ​​the splint is opposite to the claws, and the two side surfaces of the middle area are recessed to form a groove, the two claws are embedded in the splint, the claws limit the freedom of the splint by surface contact, and the upper edge of the rib abuts against the upper edge of the groove to prevent the splint from slipping.

[0005] As an improvement of the above solution, the upper edge of the rib and the upper edge of the groove are both set as inclined planes, and the inclination angles of the two inclined planes are the same. When the two claws are separated from each other, the clamping plate slowly descends and disengages from the claws under the guidance of the inclined planes.

[0006] As an improvement of the above solution, the clamping plate is provided with planes around the sink, the inclined angle of the inclined surface of the clamping claw is 10-15°, and the vertical length of the inclined surface of the clamping claw is 3-5 cm.

[0007] As an improvement of the above solution, a landing gear is provided on the lower side of the drone body, and the height of the landing gear is greater than the height of the robot dog after being installed on the drone body, ensuring that the robot dog is 3-5 cm away from the platform below when suspended.

[0008] As an improvement of the above solution, the clamping seat is fixed to the bottom of the drone body by bolts, and the clamping plate is fixed to the back of the robot dog by bolts.

[0009] As an improvement to the above solution, the areas where the screw rod passes through two different claws are respectively provided with threads with different rotation directions, and when the screw rod rotates, the two claws move together or separate at the same time.

[0010] The utility model has the following beneficial effects: the drone body and the robot dog are connected at one position, and the two claws and the clamping plate are constrained by a surface-to-surface constraint, and the limit of the edge of the rib and the edge of the sink groove can fully and stably fix the two. Since there is only one connection point, the drone body and the robot dog can be docked conveniently and quickly. The inclined design of the edge of the rib and the sink groove allows the robot dog to fall slowly to the ground, reducing the impact on the robot dog; accordingly, when the drone body re-clamps the robot dog, the two inclined surfaces will first lift the robot dog off the ground, and then the drone body will take off again.

[0018] Reference Figures 1 to 3The utility model discloses a locking device for a drone to carry a robot dog, comprising a drone body 10 and a robot dog 20 body, wherein the bottom of the drone body 10 is provided with a clamping seat 11, a guide rod located in the clamping seat 11, a screw rod 31 located in the clamping seat 11, a pair of claws 33 penetrated by the guide rod and the screw rod 31, and a motor 32 for driving the screw rod 31 to rotate, wherein the motor 32 is connected to a controller of the drone body 10, and the claws 33 are plate-shaped, and the claws 33 are close to each other. The robot dog 20 has a raised rib on one side; a clamp 21 is provided on the upper side of the back, the clamp 21 is a T-shaped steel, the clamp 21 is vertically arranged, the middle area of ​​the clamp 21 faces the claw 33, and the two sides of the middle area are recessed to form a sink 34, the two claws 33 are embedded in the clamp 21, the claws 33 limit the freedom of the clamp 21 by surface contact, and the upper edge of the rib abuts against the upper edge of the sink 34 to prevent the clamp 21 from sliding off. Figure 3 As shown, the width of the claw 33 does not exceed the width of the recess 34 .

[0019] As an improvement of the above solution, the upper edge of the rib and the upper edge of the sink 34 are both set as inclined planes, and the inclination angles of the two inclined planes are the same so that the two are in contact with each other. When the two claws 33 are separated from each other, the clamping plate 21 slowly descends under the guidance of the inclined planes and detaches from the claws 33. In other solutions, the middle of the clamping plate 21 can also be set as a slot that passes through from left to right.

[0020] As an improvement of the above solution, the clamping plate 21 is provided with planes around the sink 34, and correspondingly, the clamping claw 33 also has a plane to stably clamp the clamping plate 21, the inclination angle of the inclined surface of the clamping claw 33 is 10-15°, and the vertical length of the inclined surface of the clamping claw 33 is 3-5cm.

[0021] As an improvement of the above solution, a landing gear 12 is provided on the lower side of the drone body 10, and the height of the landing gear 12 is greater than the height of the robot dog 20 after being installed on the drone body 10, ensuring that the robot dog 20 is 3-5 cm away from the platform below when suspended. The drone body 10 is heavier after carrying the robot dog 20, and accordingly, the landing gear 12 is arranged in an arc shape so that the landing gear 12 itself can absorb part of the impact force after elastic deformation. The robot dog 20 keeps its mechanical legs retracted when being clamped, and enters the moving state after the drone body 10 leaves.

[0022] As an improvement of the above solution, the clamping seat 11 is fixed to the bottom of the drone body 10 by bolts, and the clamping plate 21 is fixed to the back of the robot dog 20 by bolts.

[0023] As an improvement of the above solution, the screw rod 31 passes through two different areas of the claws 33 and is provided with threads with different rotation directions respectively. When the screw rod 31 rotates, the two claws 33 are brought together or separated at the same time.

[0024] The drone body 10 and the robot dog 20 are connected at one position. The two claws 33 and the clamping plate 21 are constrained by a surface-to-surface constraint, and the edges of the ribs and the edges of the sink 34 are limited to fully and stably fix the two. Since there is only one connection point, the drone body 10 and the robot dog 20 can be docked conveniently and quickly. The inclined design of the edges of the ribs and the sink 34 allows the robot dog 20 to fall slowly to the ground, reducing the impact on the robot dog 20; accordingly, when the drone body 10 re-clamps the robot dog 20, the two inclined surfaces will first lift the robot dog 20 off the ground, and then the drone body 10 will take off again.
