Based on the arrangement of the positions of the battery compartment 2 and the fixing device 3 in this embodiment, each time the motor is started, the rotating member 52 drives the gripping mechanism 6 to rotate 180 °, and then the gripping mechanism 6 performs the next gripping action.

In addition, the gripping assembly 63 has a gripping function such that it can grip a battery in the unmanned aerial vehicle when approaching the unmanned aerial vehicle, or grip a battery in the battery compartment 2 when approaching the battery compartment 2. In this embodiment, the working sequence of the clamping mechanism 6 should be that when the lifting cylinder 53 drives the connecting component 61 to move to the plane where the battery is located, the moving component 62 moves to a side close to the battery relative to the connecting component 61, and at this time, the clamping component 63 is also driven to be close to the battery, and then the clamping component 63 clamps the battery.

In order to achieve the function of clamping the battery by the clamping component 63, after the moving frame 621 drives the clamping component 63 to approach the battery, the clamping component 63 should perform the action of clamping the battery, and for achieving the purpose, the clamping component 63 comprises two clamping parts which are oppositely arranged, and it can be understood that when the battery needs to be clamped, the two clamping parts are relatively close, and when the battery is placed, the two clamping parts are relatively far away, so that the battery can be put down from the clamping component 63. Specifically, each of the clamping parts includes a driving member 631, a clamping block 633 and a hinge member 632, the driving member 631 being disposed on the moving frame 621, the clamping block 633 being connected to an output end of the driving member 631 through the hinge member 632. Optionally, the driving member 631 is a linear cylinder, the linear cylinder is a pneumatic element with a piston performing linear reciprocating motion in the cylinder, and the hinge member 632 is connected to an output end of the linear cylinder, so that linear movement can be achieved, that is, when the linear cylinder works, the hinge members 632 of two opposite clamping portions can be mutually close under the driving of the linear cylinder, that is, the clamping blocks 633 connected with the hinge members 632 are mutually close to clamp the battery.
In addition, it should be noted that, the specific structure of the hinge member 632 is to ensure that the hinge member 632 can drive the clamping block 633 to move to the battery, and has a certain clamping force on the battery, and meanwhile, avoid damage to the battery due to excessive clamping force. In this embodiment, the hinge member 632 includes a spring, a first hinge portion and a second hinge portion, where the first hinge portion and the second hinge portion are disposed on two sides of the clamping block 633 relatively, as shown in fig. 3, the first hinge portion is located above the second hinge portion, and the two hinge portions are consistent in structure, so as to ensure that the force applied to the clamping block 633 is more uniform. And the first articulated part and the second articulated part that two intervals set up are connected through at least two wears to establish the pole, and the spring sets up along the axial direction of perpendicular to connecting rod, and the both ends of spring are connected respectively on different wears to establish the pole, and the one end that the spring is close to grip block 633 is close to transfer line 613 setting.

Alternatively, as shown in fig. 3, in this embodiment, each row of hinged links is formed by hinging two links, and each hinging portion is provided with two penetrating rods, one penetrating rod penetrates through each link. And two rows of articulated connecting rods are connected to one end of the clamping block 633, and are closer to one end of the driving piece 631 than to one end of the clamping block, so that a structure similar to a triangle is formed, and two abutting parts which are oppositely arranged are connected to springs on the penetrating rod due to the structure similar to the triangle formed by the articulated connecting rods, and the extending directions of the springs can be intersected, so that the springs have a force close to the direction of the transmission rod 613 on the articulated parts, and the clamping force on the battery is realized. Alternatively, the number of springs per hinge may be determined based on the torsion force of the selected springs.
Further, the clamping block 633 is provided with a sensing assembly 64, and it can be appreciated that the sensing assembly 64 is configured to sense a position of the battery, so as to implement intelligent clamping of the clamping mechanism 6. Optionally, the sensing assembly 64 is an infrared sensing device that is capable of identifying the location of the battery by temperature, which is much higher than other components of the drone body during use of the drone. Optionally, the sensing component 64 is signal-connected to the lifting cylinder 53, so that when the infrared sensing device recognizes the position of the battery of the unmanned aerial vehicle according to the temperature, the lifting cylinder 53 can be driven to move, so as to move the gripping mechanism 6 to the plane of the battery. When the sensing component 64 does not detect the battery of the unmanned aerial vehicle higher than the set temperature, a signal is transmitted to the lifting air cylinder 53, so that the lifting air cylinder 53 drives the clamping mechanism 6 to move in the vertical direction according to a preset program.
The above-described arrangement of the sensing assembly 64 and the lift cylinder 53 is primarily concerned with the process of changing batteries for the drone. It is known that as the battery compartment 2, it is preferable to have the capability of storing a plurality of batteries to fulfill the need for a plurality of unmanned aerial vehicles or for a plurality of battery exchanges. When the battery is replaced, the sensing device on the clamping block 633 on the side of the unmanned aerial vehicle recognizes the position of the battery of the unmanned aerial vehicle through temperature, and then the sensing device transmits signals to the lifting cylinder 53 connected with the side clamping mechanism 6, the lifting cylinder 53 moves in the vertical direction so as to send the clamping block 633 to the plane where the battery is located, and then the moving frame 621 moves relative to the connecting plate 611, so that the clamping block 633 is driven to clamp the battery. The sensing device on the clamping block 633 at the side of the battery compartment 2 fails to recognize the position of the battery of the unmanned aerial vehicle through temperature, and then transmits a signal to the lifting cylinder 53 connected with the side clamping mechanism 6, the lifting cylinder 53 drives the clamping mechanism 6 to move in the vertical direction according to a preset program, so as to send the clamping block 633 to the plane of a certain battery in the battery compartment 2, and then the moving frame 621 moves relative to the connecting plate 611, so as to drive the clamping block 633 to clamp the battery.
