As shown in fig. 2 to 5, the charging plate 100 is provided with 2 sets corresponding to the receiving plate, and similarly, the floating device 300 is provided with 2 sets corresponding to the charging plate 100. Each set of floating devices 300 comprises a lower connecting plate 301, a plate spring 302, an upper connecting plate 303, a connecting snap ring 304, an elastic device 305, a connecting seat 306 and a sensor 307.

Plate spring 302 is the bow-shaped, bottom surface both sides and lower connecting plate 301 swing joint, middle bow face and upper junction plate 303 fixed connection, and lower connecting plate 301 is connected through connecting snap ring 304 with upper junction plate 303 both sides, and connects snap ring 304 and lower connecting plate 301 for pin junction, with upper junction plate 303 swing joint, and passes through it makes to connect snap ring 304 the plate spring has certain pretension tension. At this time, the lower connecting plate 301, the plate spring 302, the upper connecting plate 303, and the connecting snap ring 304 together constitute a suspension mechanism. When the charging pole plate 100 is pressed down to be contacted with a receiving pole plate, the pre-tightened arched plate spring 302 is pressed to extend towards two sides, an elastic pre-tightening state is kept, a good contact buffering effect is achieved, meanwhile, vibration generated in the contact process of the two pole plates can be effectively reduced, and the stability and the reliability of the contact process are greatly improved.

The elastic means 305 is a rubber elastic member including a fixing frame 3051 fixedly coupled to the coupling holder 305, a block 3052 fixedly coupled to the upper coupling plate 303, a rubber block 3053 elastically contacting the block 3052, and a housing 3054 fixing the rubber block 3053 and the block 3052.

The connecting base 306 is connected with the frame 400 through bolts and springs in a pre-tightening mode, the sensor 307 is a pressure sensor and is arranged between the connecting base 306 and the frame 400, therefore, the whole floating moving device 300 is only contacted with the frame 400 through the sensor 307, the sensor 307 measures the contact pressure between the floating device 300 and the frame 400, the value of the contact pressure includes the connection pre-tightening force between the connecting base 306 and the frame 400 and the contact pressure between the charging pole plate 100 and the current-receiving pole plate, when the charging pole plate 100 is not contacted with the current-receiving pole plate, the value of the contact pressure is unchanged, after the contact pressure is changed, the change of the value is the contact pressure, when the contact pressure reaches a preset range, the charging bow stops pressing, and the charging contact pressure of the charging pole plate.

The working mode of the charging bow is as follows:

when the charging equipment receives a charging signal, the lifting mechanism pushes the charging bow to extend downwards to be in contact with the charging vehicle pantograph, when the current-collecting electrode plate 500 is not in height difference and inclined, the 2 groups of charging electrode plates 100 are simultaneously in contact with the current-collecting electrode plate 500, the sensor 307 arranged between the connecting seat 306 and the frame 400 detects the contact pressure, when the set contact pressure range value is not reached, the lifting mechanism pushes the frame 400 to continuously press downwards, the plate spring 302 is pressed and plays a role in damping and buffering, and charging is started until the set contact pressure is reached.

When the receiving electrode plate 500 has a height difference and an inclination in the transverse direction, as shown in fig. 6, when the charging electrode plate 100 is pressed down, the charging electrode plate 100 is firstly contacted with the receiving electrode plate 500 with a higher position, the other group of charging electrode plates 100 is not stressed, at this time, a deflection force is generated on the floating device 300, and when the plate spring 302 is subjected to vibration reduction and buffering, the elastic device 305 automatically generates corresponding deflection under the action of the transverse bias force of the suspension mechanism, so that the other group of charging electrode plates 100 is contacted with the corresponding receiving electrode plate 500, and it is ensured that both groups of charging motor plates can obtain an effective contact area until a set contact pressure is reached; similarly, when the current-receiving electrode plate 500 has a vertical height difference and an inclination, the elastic device 305 automatically generates a corresponding deflection under the action of the vertical deflection of the suspension mechanism, so as to ensure that the two groups of charging motor plates can obtain an effective contact area until a set contact pressure is reached, and then the charging is started.

After the charging is finished, the frame 400 rises along with the lifting mechanism, the charger board 100 is separated from the current-receiving electrode board 500, and the floating device 300 can naturally return to the initial state of vertical downward through the return characteristic of the elastic device 305 without being affected by external force.
