Description

A wireless automatic charging system for quadcopter

technical field

The utility model relates to a charging device, in particular to a wireless automatic charging system for a four-axis aircraft.

Background technique

A multi-axis aircraft is a common aircraft that can perform stable control flight. It performs stable control flight by using inertial navigation technology, and changes the flight direction by changing the rotation speed of the blades. Due to the compact structure of the multi-axis aircraft, it has a strong ability to resist harsh environments, coupled with its flexible movement, it is relatively simple to change its own flight direction, and is suitable for use in narrow and dangerous areas. For example, a quadcopter is a small aircraft with four propellers in a cross-shaped layout. The four propellers are simple mechanisms directly connected to the motors. The cross-shaped layout allows the aircraft to rotate the fuselage by changing the motor speed. force to adjust their posture.

Due to the limited load of the quadrocopter, most of the batteries of the existing quadrocopter do not have a long power supply time, and will be charged after flying for a period of time, and the lack of continuous flight time has always been an existing problem. The existing technology mainly uses manual or wired charging, which is cumbersome and cannot meet the requirements of real-time charging.

Utility model content

The purpose of the utility model is to provide a simple, convenient and reliable wireless automatic charging system for a four-axis aircraft in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A wireless automatic charging system for a four-axis aircraft. The four-axis aircraft is provided with a four-axis support frame. The charging system includes a power base station and a charging bracket arranged on the four-axis aircraft. The end surfaces of each leg of the charging bracket are Rechargeable contacts and a first infrared detector are respectively provided on the base station, the power base station includes a charging contact, a second infrared detector and a base station power supply, and the end faces of the legs of the charging bracket are higher than the end faces of the legs of the four-axis support frame, The power supply of the base station is connected to the charging contact, and when charging, the rechargeable contact is in contact with the charging contact through the positioning of the first infrared detector and the second infrared detector.

The charging contacts protrude from the power base station.

Two charging contacts are provided, and two charging contacts are provided correspondingly.

Both the rechargeable contact and the charging contact are sheet metal contacts.

A permanent magnet is arranged around the charging contact, and an electromagnetic coil corresponding to the permanent magnet is arranged around the charging contact.

The electric power base station also includes an electromagnetic coil power supply for supplying electric power to the electromagnetic coil.

Compared with the prior art, the utility model uses contacts to wirelessly charge the quadcopter, which is convenient and reliable, and has a wide range of applications, eliminating the cumbersome wire connection and manual operation of ordinary charging, and the power base station can be fixed on the ground or mounted on a vehicle or shipboard. When the power base station is mounted on a movable platform, a large range of movement can be realized through the platform.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the utility model, and the detailed implementation and specific operation process are given, but the protection scope of the utility model is not limited to the following examples.

As shown in Figures 1-4, this embodiment provides a wireless automatic charging system for a quadcopter. The quadcopter is provided with a quadcopter support frame 1, and the charging system includes a power base station and a charging system located on the quadcopter. Bracket 2, the end faces of each leg of charging bracket 2 are respectively provided with rechargeable contact 3 and first infrared detector 4, the power base station includes charging contact 5, second infrared detector 6 and base station power supply, base station power supply and charging contact Point 5 is connected, when charging, through the positioning of the first infrared detector 4 and the second infrared detector 6, the rechargeable contact 3 is in contact with the charging contact 4 to complete automatic charging. There are two charging contacts 3 and two charging contacts 5, both of which are sheet metal contacts. When the power base station can be mounted on a movable platform, a large range of movement can be realized through the platform, and charging is more convenient.

The leg end face of the charging bracket 2 is higher than the leg end face of the four-axis support frame 1, preventing the four-axis from landing on muddy land and other places with bad road conditions such as impurities from contaminating the contacts. The charging contact 5 protrudes from the power base station.

Permanent magnets are arranged around the charging contact 3 , and electromagnetic coils corresponding to the permanent magnets are arranged around the charging contact 5 to realize the fixing of the charging contact 3 and the charging contact 5 . The power base also includes a solenoid power supply for providing power to the solenoid.

When charging, the navigation and positioning system in the quadcopter initially locates the quadcopter above the power base station, and then the first infrared detector 4 and the second infrared detector 6 perform precise positioning. When the power base station receives the correct positioning When signaling, turn on the electromagnetic coil power supply and the base station power supply; when the quadcopter is fully charged and sends out a signal, turn off the magnetic coil power supply and the base station power supply to complete the automatic charging process.
