Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement for unmanned aerial vehicles, in particular to an automatic battery replacement fixture for unmanned aerial vehicles at an automated airport. Background Art

[0002] With the continuous development of drone technology, drones have become important equipment in many industries. In order to enable drones to perform tasks intelligently and automatically, drone automatic airports have emerged. When a drone completes its mission and returns to the automatic airport, the automatic airport will automatically replace the battery of the drone.

[0003] At present, the power source clamped by the battery replacement mechanism of drones is mostly pneumatic. It is common for water to accumulate in the air circuit. When the battery replacement mechanism of drones is in cold conditions (winter, especially in open air), the water in the air circuit will freeze and block the air pipe, reducing the reliability of the battery replacement mechanism. If there is a leak in the air pipe or the pipe joint, the battery clamped by the pneumatic battery replacement mechanism may fall off and the battery may be damaged. If there is a leak in the air pipe or the pipe joint, the air pump will continue to work, which will not only shorten the service life of the air pump, but also cause safety hazards.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-8 As shown, an automatic battery replacement fixture for unmanned aerial vehicles at an automated airport includes a fixture body 11, which is composed of a static clamping plate 111 and a dynamic clamping plate 112. The static clamping plate 111 and the dynamic clamping plate 112 are slidably connected, and an electric drive device for driving the dynamic clamping plate 112 to move is provided on the static clamping plate 111. The fixture body and the drive device together form the automatic battery replacement fixture 1 for unmanned aerial vehicles.

[0034] As a specific implementation, a static clamping plate clamping arm 1111 perpendicular to the static clamping plate 111 is extended from one side of the static clamping plate 111 away from the dynamic clamping plate 112, and a dynamic clamping plate clamping arm 1123 extending in the same direction as the static clamping plate clamping arm 1111 is provided on one side of the dynamic clamping plate 112 away from the static clamping plate 111. In this way, the static clamping plate 111 and the dynamic clamping plate 112 together form a clamp with a U-shaped structure, and the size of the clamping opening is controlled by driving the dynamic clamping plate 112 to move by an electric drive device, thereby completing the clamping and placement of the drone battery.

[0035] As a specific implementation, a linear slide rail 113 is provided on the inner side of the static clamping plate 111 (the inner side is the side opposite to the static clamping plate 111 and the dynamic clamping plate 112), and a slider 114 matching with the linear slide rail 113 is provided on the inner side of the dynamic clamping plate 112. The stability and accuracy of the movement of the dynamic clamping plate 112 are ensured by the sliding connection of the slide rail and the slider.

[0036] As a specific embodiment, the electric drive device includes a screw stepper motor 12 arranged on a static clamping plate 111, and the power output shaft of the screw stepper motor 12 is cooperatively connected with a screw 121, and the dynamic clamping plate 112 is provided with a screw nut 1121 cooperatively connected with the screw 121. The screw stepper motor 12 electrically drives the screw 121 to drive the screw nut 1121 to move, and then drives the dynamic clamping plate 112 to move, thereby realizing the clamping or loosening action of the clamp, ensuring the stability of the process of clamping the mobile battery, and not being affected by weather and temperature.

[0037] Furthermore, the inner sides of the static clamping plate clamping arm 1111 and the dynamic clamping plate clamping arm 1123 are provided with anti-slip rubber pads (not shown in the figure), which further increase the clamping friction of the clamping arm. At the same time, the rubber pads have a certain buffering effect, forming a clamping protection effect on the clamped battery assembly.

[0038] Specifically in this embodiment, the screw stepper motor 12 is fixed to the side of the static clamping plate 111 close to the static clamping plate clamping arm 1111 by fasteners, and a screw nut support 1122 is provided on the side of the dynamic clamping plate 112 away from the dynamic clamping plate clamping arm 1123, and the screw nut 1121 is fixed on the screw nut support 1122.

[0039] Specifically in the present embodiment, a sensor assembly 13 is also included, and the sensor assembly 13 is composed of a front sensor 131 and a rear sensor 132. The front sensor 131 and the rear sensor 132 are infrared detection sensors, etc. The front sensor 131 and the rear sensor 132 are both fixed on the static clamping plate 111, and the front sensor 131 is arranged on a side close to the static clamping plate clamping arm 1111, and the rear sensor 132 is arranged on a side away from the static clamping plate clamping arm 1111; the dynamic clamping plate 112 is provided with a detection baffle 133 corresponding to the level of the front sensor 131 and the rear sensor 132. The moving clamping plate 112 drives the detection baffle 133 to move during its movement. When the front sensor 131 or the rear sensor 132 detects that the detection baffle 133 passes by, the moving clamping plate 112 stops moving. The front sensor 131 is used to control the shortest sliding distance of the moving clamping plate 112 (the state of clamping the battery assembly), and the rear sensor 132 is used to control the farthest sliding distance of the moving clamping plate 112 (the state of releasing and detaching the battery assembly from the clamp body 11).

[0040] Specifically, the specific setting position of the front sensor 131 is determined according to the actual length of the battery assembly to be clamped, and the rear sensor 132 is adaptively installed according to the setting position of the front sensor 131.

[0041] Of course, the present embodiment also includes a stepper motor driver 6 for controlling the detection signals received from the front sensor 131 and the rear sensor 132, and for controlling the screw stepper motor 12. The front sensor 131 and the rear sensor 132 are electrically connected to the stepper motor driver 6 through the PLC controller 5, and the stepper motor driver 6 is electrically connected to the screw stepper motor 12. The above electrical connection methods all belong to the existing conventional technology, and the specific connection methods are not described in detail here.

[0042] Working principle: When in use, the automatic battery replacement fixture 1 for unmanned aerial vehicles cooperates with the collaborative robot 2 to clamp and transport the battery assembly. The collaborative robot 2 drives the fixture body 11 to the side of the unmanned aerial vehicle battery 41 that is slidably mounted on the unmanned aerial vehicle 4, and aligns the static clamping plate clamp arm 1111 and the dynamic clamping plate clamp arm 1123 with the front and rear ends of the unmanned aerial vehicle battery 41. The screw motor 12 drives the fixture body 11 to clamp the battery, and the collaborative robot 2 drives the automatic battery replacement fixture 1 for unmanned aerial vehicles to remove the unmanned aerial vehicle battery 41 from the unmanned aerial vehicle 4. Then the collaborative robot drives the automatic battery replacement fixture 1 for unmanned aerial vehicles to move the unmanned aerial vehicle battery 41 to the automatic airport battery compartment 3. The screw motor 12 drives the fixture body 11 to release the unmanned aerial vehicle battery 41, and the battery is charged in the automatic airport battery compartment 3.

[0043] The collaborative robot 2 drives the fixture body 11 to the side of the battery compartment battery 31 slidably mounted on the battery compartment 3 of the automated airport, and aligns the static clamping plate clamp arm 1111 and the dynamic clamping plate clamp arm 1123 with the front and rear ends of the battery compartment battery 31. The screw motor 12 drives the fixture body 11 to clamp the battery compartment battery 31, and removes the fully charged battery compartment battery 31 on the automated airport battery compartment 3. Then the collaborative robot drives the fixture 1 to move to the battery slot of the drone 4, and the screw motor 12 drives the fixture body 11 to release the battery compartment battery 31, and the battery is installed on the drone 4.
