[0076] The use process of the inverter control system, the inverter and the charging equipment provided by the application is as follows:

[0077] When the inverter assembly 6 is connected with the charging assembly 1 through the wires, and the two U-shaped slide rails 301 connected by the automatic spring barrel 302 on the charging shell 101 are close to each other, at this time in the charging state, the rolling shafts 205 connected by the rolling blocks 206 in the middle of the U-shaped slide rails 301 are close to each other, then the two ends of the air bag 203 wrapped on the rolling shafts 205 are close to or away from each other, thereby controlling the area of the air bag 203 to cover the air vents 102 opened on the charging shell 101, then the area of the air vents 102 exposed can be controlled, thereby controlling the charging under different power to control the size of ventilation, and dust can also be prevented from entering in large quantities when the air vents 102 are exposed in a large area. When a fire occurs, the automatic spring barrel 302 will move the U-shaped slide rails 301 away from each other, at this time the air pump 201 on the charging shell 101 will suck the gas inside into the air bag 203 through the suction pipe 202, at this time the air bag 203 will become inflated from the shriveled state, at this time the two groups of rolling shafts 205 will move away from each other, so that the area of the air bag 203 can cover the air vents 102, at this time the air bag 203 will contact the pressing plate 204 and cannot be inflated any more. The air bag 203 contains fire extinguishing powder, at this time the gas in the air bag 203 will be mixed with the fire extinguishing powder and sprayed out of the air bag 203 through the one-way valve on the surface of the air bag 203, and then enters the inside of the charging device through the air vents 102, thereby extinguishing the fire. At the same time, the air bag 203 completely covers the air vents 102, thereby sealing the charging shell 101, thereby isolating the entry of air, thereby effectively improving the intensity of fire extinguishing,

[0078] The magnetic rods 502 are connected between the two groups of rolling shafts 205 through the circular grooves, and will be exposed when the rolling shafts 205 move away from each other. The folded pressing resonance plates 501 are hinged at the protrusions of the multiple U-shaped grooves opened on the surface of the rolling shafts 205, at this time the folded pressing resonance plates 501 will be pulled up when the rolling shafts 205 move away from each other, at this time the gas will be filled in, and then a sound will be produced, thereby alarming. The opposite end of the folded pressing resonance plates 501 to the magnetic rods 502 is the same magnetic pole, at this time the interaction of the magnetic fields generated by the two magnetic positions can cause the folded pressing resonance plates 501 to vibrate, which is realized by using the magnetostrictive effect, thereby causing the folded pressing resonance plates 501 to vibrate, thereby greatly vibrating the surface of the air bag 203, so that the fire extinguishing powder in the air bag 203 will be vibrated, thereby fully mixing with the gas filled in the air bag 203, thereby making the fire extinguishing effect better,

[0079] When the charging device is not used for a long time, at this time the arc-shaped plate 404 hinged at both ends of the U-shaped slide rail 301 will be flipped down, and then the two arc-shaped plates 404 together cover the charging port 103 through the rectangular plate 405 connected in the rectangular through slot, so as to avoid the charging port 103 being contacted by dust and water for a long time. When the charging head is inserted into the charging port 103, at this time the rectangular plate 405 connected through the rectangular through slot on the arc-shaped plate 404 is adjusted in position under the control of the automatic telescopic rod 406, leaving space so that the upper and lower positions of the clamping column charging head are left, at this time the L-shaped folding pipe 407 is extruded by the arc-shaped plate 404, at this time the circular recess is provided on the inner wall of both sides of the rectangular through slot and communicates with the L-shaped folding pipe 407, when the L-shaped folding pipe 407 is extruded by the arc-shaped plate 404, the internal gas will be discharged through the one-way air valve provided in the suction cup 408, at this time suction force will be generated, so that the two sides of the charging head are fixed, so that the charging head is fixed around, preventing the charging head from being separated from the charging port 103 in the case of relatively bumpy conditions, at the same time when the charging device is abnormal, at this time the charging head needs to be separated from the charging port 103, at this time the sliding plate 401 connected with the U-shaped slide rail 301 is pushed forward by the fixed extrusion elastic cylinder 402 behind the sliding plate 401 under the control of the system, the sliding plate 401 is hinged with the arc-shaped plate 404, which makes the arc-shaped plate 404 also move forward, so that the arc-shaped plate 404 fixed with the charging head is quickly separated from the charging port 103, so as to cut off the power in time, so as to avoid the danger of the charging device being further aggravated.

[0080] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connection", "connecting", "fixed", and the like should be interpreted broadly, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected or can communicate with each other; can be directly connected, or can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited.
