Embodiment 1

[0036] like Figure 1 to Figure 10 As shown, this embodiment provides a grasping device that can be used for battery replacement of a drone, including a mechanical claw 1 and a mechanical arm 2 matched with the mechanical claw 1. The mechanical claw 1 includes a base 11, a torsion spring 15, a rudder 13, the steering wheel 14 and the clamping jaws 12 arranged on both sides of the base 11; the steering gear 13 is fixedly connected with the steering wheel 14, a wire rope is installed between the steering wheel 14 and the clamping jaw 12, and the base 11 is fixedly connected to the mounting plate 16, The mounting plate 16 is movably connected with the clamping jaw 12, the torsion spring 15 is installed on the mounting plate 16, and the torsion spring 15 is movably matched with the clamping jaw 12; when the steering gear 13 drives the steering wheel 14 to rotate, the steering wheel 14 drives the wire rope to move, and The grasping part 122 of the linkage jaw 12 is opened; when the...

Embodiment 2

[0048] This embodiment provides a grabbing device that can be used for UAV battery replacement. The difference from Embodiment 1 is:

[0049] like Figure 11 As shown, in this embodiment, the manipulator and the manipulator are respectively controlled by the lower computer, the lower computer sends a pulse signal to the motor through the driver, and the lower computer sends a PWM signal to the steering gear through the controller, and controls the manipulator through the motor and the steering gear respectively. Movement with mechanical claw. The motor and servo are powered by the power supply and controlled by the switch. It is beneficial to the cooperative movement of the mechanical claw and the mechanical arm when grabbing the battery, improving the accuracy and facilitating the control.

[0050] The linear motion manipulator and the manipulator are installed and fastened together, and the lower computer executes the control commands to the motor and the steering gear, so...

Embodiment 3

[0053] This embodiment provides a grabbing device that can be used for UAV battery replacement. The difference from Embodiment 1 is:

[0054] In this embodiment, the grasping device has a waterproof function, and the linear motion manipulator is fixed in the casing. When the lithium polymer battery of the drone is replaced, it can be grasped by the manipulator and stored in the middle of the casing. The mechanical parts of the grabbing device are all aluminum alloy, stainless steel or nylon parts, and the motor and steering gear also have waterproof function, and the circuit connection has no exposed interface, so it can play a waterproof safety function. The grabbing device for battery replacement on the drone power exchange ground station is rainproof and can be placed outdoors, but due to the lithium polymer battery, the grabbing device is not suitable for immersion in water or heavy rain.

[0055] For other specific structures, refer to Embodiment 1.

Abstract

The invention belongs to the technical field of unmanned aerial vehicle battery replacement, and particularly relates to a grabbing device for replacing a battery of an unmanned aerial vehicle. The grabbing device comprises a mechanical claw and a mechanical arm matched with the mechanical claw, and the mechanical claw comprises a base, torsional springs, a steering engine, a steering wheel and clamping claws arranged on the two sides of the base; the steering engine is fixedly connected with the steering wheel, a steel wire rope is installed between the steering wheel and the clamping claws,the base is fixedly connected with installation plates, the installation plates are movably connected with the clamping claws, and the torsional springs are installed on the installation plates and movably matched with the clamping claws; when the steering engine drives the steering wheel to rotate, the steering wheel drives the steel wire rope to move and is linked with the grabbing parts of theclamping claws to open; when the steering wheel stops rotating, under the action of the torsional springs, the grabbing parts of the clamping claws are tightened towards the middle, so that the clamping claws grab the battery and push the battery to the unmanned aerial vehicle in cooperation with the mechanical arm; and a hand and elbow mechanism is achieved through the linear motion mechanical arm and the mechanical claw, the purpose of replacing the lithium battery of the unmanned aerial vehicle is achieved, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of UAV battery replacement, and in particular relates to a grasping device that can be used for UAV battery replacement. Background technique [0002] UAV automatic battery replacement technology is an effective way to solve the problem of long battery life and automation of UAV. For drones, lithium polymer batteries (which are generally used) are generally fastened to the drone body to ensure flight safety. [0003] In the prior art, for example, the patent document with the application number CN201920619452.6 discloses a UAV battery replacement mechanism, including a take-off and landing platform, a positioning component, a battery replacement component and a plurality of battery charging compartments; the take-off and landing platform , used for take-off and landing of drones; positioning components, set on the take-off and landing platform, used to center and fix the landing drone; multiple battery char...
