Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a battery gripping device for UAV nests. Background Technology

[0002] Most of the drones currently used for inspection, reconnaissance, and other tasks are traditional quadcopter drones that use the flight principle of helicopters. These drones can stop and go at any time, making them suitable for inspection, reconnaissance, and other tasks. However, their short range and flight time limit their efficiency and scope of operation.

[0003] Chinese patent document CN 220865682 U discloses a multi-rotor drone that solves the aforementioned problems. However, when the multi-rotor drone's battery runs out, it needs to be replaced, which requires battery removal. Battery removal requires pressing two spring caps simultaneously to disengage two limiting blocks from their corresponding limiting slots. In existing technology, this is usually done manually by pressing the two spring caps. However, manual pressing is difficult because the human hand cannot properly align with the spacing between the two spring caps, and manual disassembly is inefficient. Utility Model Content

[0004] This invention provides a battery gripping device for drone nests to solve the technical problem of batteries being difficult to remove in the prior art.

[0005] To solve the above problems, the present invention provides a battery gripping device for a drone nest, which adopts the following technical solution:

[0006] A battery gripping device for a drone nest includes a base, a drive component, a transmission component, and two gripping claws. The transmission component is rotatably mounted on the base, and the drive component is fixed on the base and driven by the transmission component to drive the transmission component to rotate. The two gripping claws are symmetrically arranged on both sides of the transmission component and are rotatably mounted to the base. The gripping ends of the gripping claws are provided with top blocks that are adapted to fit spring caps on the drone to grip the spring caps. The transmission component has two symmetrically arranged arc-shaped surfaces that respectively press against the corresponding gripping claws. When the transmission component rotates in both directions, it drives the two gripping claws to open and close by pressing against the transmission surfaces.

[0007] The beneficial effects are as follows: When using the battery gripping device for a drone's nest, rotating the gripping claws causes the top blocks at the left ends of the two gripping claws to abut against the spring caps. Continuing to rotate the gripping claws causes the top blocks to push against the spring caps, moving them and causing the two limiting blocks to disengage from their corresponding limiting slots. At this point, the battery can be removed from the drone. The battery gripping device for a drone's nest is simple to operate, has a simple structure, and facilitates battery removal.

[0008] Furthermore, the driving component is a gripping motor.

[0009] Beneficial effects: Automatic grasping, simple structure, and easy operation.

[0010] Furthermore, the length direction of the base is defined as the left-right direction, the transmission component is a transmission plate, the front end face and the rear end face of the transmission plate are the arc-shaped surfaces, and each arc-shaped surface is a symmetrical structure about the left-right direction. Each arc-shaped surface is symmetrically arranged in the left-right direction. The output shaft of the gripping motor and the center of the transmission plate are coaxially fixed. The gripping claw includes a first claw segment and a second claw segment. The first claw segment and the second claw segment are rotatably assembled on the base at the connection position. When the gripping claw is in the initial position, the right end of the first claw segment of the two gripping claws contacts and connects with the middle position of the arc-shaped surface on the corresponding side.

[0011] Beneficial effect: One gripping motor drives two holding claws to rotate synchronously, ensuring the stability of gripping the battery.

[0012] Furthermore, each of the first claw segments has a rotating groove extending horizontally at its right end. The upper and lower side walls of the rotating groove have through holes, and a rotating rod is installed in the through holes. A rotating wheel installed in the rotating groove is rotatably mounted on the rotating rod. When the gripping claw is in the initial position, the rotating wheel contacts and connects with the end point of the arc-shaped surface on the corresponding side.

[0013] Beneficial effects: Simple structure, stable rotation, and avoids friction damage to the gripping claws.

[0014] Furthermore, a blind hole is provided on the base, and a rotating rod is provided inside the blind hole. A rotating hole adapted to the rotating rod is provided at the connection position of the first claw segment and the second claw segment. The gripping claw is rotated and assembled on the rotating rod.

[0015] Beneficial effects: Simple structure, easy to install and disassemble.

[0016] Furthermore, a stabilizing rod extending in the front-to-back direction is connected between the two first claw segments. The stabilizing rod is a telescopic rod, and its two ends are respectively hinged to the first claw segment on the corresponding side.

[0017] Beneficial effect: Improves the stability of the gripper during rotation.

[0018] Furthermore, a soft pad is fitted on the left end of the second claw segment, and the top block is placed on the soft pad.

[0019] Beneficial effect: Protects the spring cap and gripper claws from damage.

[0020] Furthermore, one end of the spring cap on the top block used to hold the drone is pointed.

[0021] Beneficial effect: Improves stability when holding the battery. Attached Figure Description
