TECHNICAL FIELD
[0001] The utility model belongs to the technical field of inspection robot, more particularly, it relates to a four-legged robot wireless charging structure. BACKGROUND
[0002] With the rapid development of charging technology, wireless charging technology is widely used in consumer electronics, medical home, power inspection and other fields. The essential principle of wireless charging technology is electromagnetic induction, including energy transmitting end and receiving end. The alternating current inside the transmitting end generates a changing magnetic field, which is transmitted to the mapped receiving end through the air medium. The receiving end induces current according to the changing magnetic field, so as to generate the required power of the terminal device.
[0003] In the substation, four-legged robots are widely used for intelligent inspection, real-time monitoring of related data of power equipment, and effectively promote the process of unmanned construction in the substation. At present, the charging method of four-legged robot generally adopts the battery core adaptive docking mode. Because of the large workload of four-legged robot in the station, the number of cyclic charging is large, and the battery contact end often has the phenomena of wear, stain, poor contact and so on. The battery end is in a bare state during charging, and there are certain safety hazards and reliability problems in humid and muddy environment. For the wireless charging power inspection application, there is also a positioning accuracy problem of the transmitting end and the receiving end, which affects the charging efficiency and reliability.
[0004] For the existing technology of document 1, the multi-legged robot adopts stereo vision camera, but it cannot guarantee the center alignment of the wireless transmitting device and the receiving device, and can only be close to the center as much as possible, which leads to the decline of charging efficiency or unstable charging frequency, and the charging interruption phenomenon occurs. At the same time, such charging scheme usually does not consider the heat dissipation condition of the device itself, and the high temperature rise also affects the charging performance and the long-term life of the device.
[0005] For the existing technology of document 2, the multi-legged robot is equipped with a unmanned aerial vehicle, and then the unmanned aerial vehicle and the four-legged robot are difficult to center. At the same time, in a small area, it is difficult to coordinate the posture of the unmanned aerial vehicle and the posture of the four-legged robot, and the centering recognition of the unmanned aerial vehicle and the four-legged robot is difficult, so it is difficult to guarantee the quality of each charging; the electromagnetic iron is used to adsorb the unmanned aerial vehicle, which cannot guarantee that the unmanned aerial vehicle is stationary with the movement of the multi-legged robot, and the centering accuracy is insufficient; in addition, the electromagnetic induction depends on the changing magnetic field. If the external magnetic field (such as the magnetic field generated by the electromagnet) changes near the coil of the wireless charger, it is easy to cause additional induced current in the coil of the charger, which further reduces the charging efficiency and generates heat, and even damages the equipment. When the magnetic field strength of the electromagnet is large enough, it will also change the magnetic circuit of the wireless charging system, which will reduce the energy transmission efficiency; at the same time, the charging capacity of the charging module carried by the unmanned aerial vehicle itself cannot meet the sustainable demand.
[0006] The prior art of the file 2 has a multi-legged robot using solar charging, but the solar wireless charging is limited by weather and light, the capacity transmission is intermittent, and when the heat generated by the solar cell substrate cannot be dissipated in time, the multi-legged robot is easy to cause the temperature of the mounting surface to rise, the heat is transferred to the inside of the multi-legged robot, and then the internal temperature is too high, which affects the normal work of other components and reduces the overall performance and stability of the multi-legged robot, and the charging structure of the solar energy is complex, and the cost is relatively high compared with the transmitter and receiver type.

[0040] As Figures 4-5 shown, the four-legged robot torso 2 body includes the body frame 21, the battery module 22 and the second plastic baffle 23. The battery module 22 is arranged in the body frame 21, and the second plastic baffle 23 is located on the side of the body frame. The battery module 22 includes a battery body 221 and a receiving assembly 222, one side of the battery body 221 is a "concave" structure, and the side is provided with the receiving assembly 222.
