Embodiment 1

[0063] This embodiment provides a wireless charging device in an explosion-proof scenario, such as figure 1 As shown in the figure, for wirelessly charging the movable electromechanical device 2, a charging receiving terminal 3 is arranged at the bottom of the movable electromechanical device 2, and the wireless charging device includes:

[0064] The charging and transmitting end 4, the charging and transmitting end 4 is arranged in the retractable water storage tank 5, and the charging and transmitting end 4 is used for coordinating with the charging and receiving end 3 for charging;

[0065] A retractable water storage tank 5, the retractable water storage tank 5 is configured to drive the charging transmitting end 4 to approach the charging receiving end 3 for charging when extended, and drive the charging transmitting end 4 away from the charging terminal 4 when retracted The charging receiver 3 ends charging;

[0066] Water medium 7, which is arranged in the telescopic w...

Embodiment 2

[0075] This embodiment discloses a wireless charging method in an explosion-proof scenario, and the wireless charging method in an explosion-proof scenario is used for the wireless charging device in the explosion-proof scenario as described in Embodiment 1.

[0076] The method includes:

[0077] Step S1: the movable electromechanical device 2 moves to the upper side of the adjacent telescopic water storage tank 5 when the remaining power of the movable electromechanical device 2 is insufficient or after receiving the "charging" command;

[0078] Step S2: after the charging receiving end 3 and the charging transmitting end 4 are aligned, the movable electromechanical device 2 stops moving;

[0079] Step S3 : the retractable water storage tank 5 rises, so that the charging receiving end 3 enters the charging range of the charging transmitting end 4 , and after the upper surface of the water medium 7 submerges the charging receiving surface of the charging receiving end 3 , the ...

Abstract

The invention provides a wireless charging device and method for an explosion-proof scene, the charging device is used for wirelessly charging a movable electromechanical device, the bottom of the movable electromechanical device is provided with a charging receiving end, the charging device comprises a charging transmitting end, the charging transmitting end is arranged in a telescopic water storage tank, and the charging receiving end is connected with the telescopic water storage tank; the charging transmitting end is used for matching with the charging receiving end for charging; when the telescopic water storage tank stretches out, the charging transmitting end is driven to be close to the charging receiving end, and when the telescopic water storage tank retracts, the charging transmitting end is driven to be away from the charging receiving end; and the water medium is arranged in the telescopic water storage tank, the water medium submerges the charging transmitting end, and during charging, the upper surface of the water medium submerges the wireless charging receiving surface of the charging receiving end. Through the arrangement of the telescopic water storage tank and the charging transmitting end and the water medium in the telescopic water storage tank, water sealing of the charging structure in the wireless charging process is achieved, energy release in the charging process is isolated, and the charging safety in an anti-explosion scene is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of safe charging in explosion-proof scenarios, and in particular, to a wireless charging device and method in explosion-proof scenarios. Background technique [0002] Mobile robots are used in environments with flammable and explosive gases or dust, and must meet relevant explosion-proof requirements. This is because mobile robots occasionally generate ignition sources or static electricity during operation, which can easily cause combustion or explosion when encountering dangerous gases or dust that leak, evaporate or diffuse. Mobile robots must carry out explosion-proof certification for the body, charging device, driving device, navigation device, communication device and other components. Specifically, each component such as battery, charger, sensor, and drive motor needs to meet explosion-proof standards, including cable connection, arrangement of different electrical components, isolation, etc...
