It should be noted that when the charging blade 10 is disengaged from the trough body 230, the two charging plates 200 are moved toward each other, and the buffering members on the two charging plates 200 can support each other to avoid direct contact between the two charging plates 200 to eliminate collisions. noise. When the charging board 200 enters the tank body 230, the body portion 120 presses the two charging plates 200 to separate the buffer members on the two charging plates 200 from each other with a separation pitch at least larger than the thickness of the connecting portion 110. Thereby, when the main body portion 120 of the charging blade 10 passes in the groove body 230, the connecting portion 110 of the charging blade 10 can smoothly pass through the running groove, and the interference of the cushioning member with the connecting portion 110 can be avoided.

Both of the charging plates 200 include a plurality of segment plates that are sequentially connected in the traveling direction of the rail vehicle.

The first extension plate and the second extension plate extend toward the ends of each other and the first extension plate extends between the second extension plates, and the gap between the first extension plate and the second extension plate has a gap of 2 mm to 5 mm to make the phase The two adjacent segments are movably connected.

As shown in FIGS. 1-3, the connection assembly 250 includes an outer cylinder 251, an inner cylinder 252, and an elastic member 253. The outer tube 251 is an insulating member. The outer tube 251 has a limiting portion 2511 near the end of the elastic member 253. The fixing plate 270 is attached to the outer tube 251 and is fixed to the outer tube 251 and fixed to the limiting portion 2511. The plate 270 is coupled to the housing 240 by bolts. The first end 2521 of the inner cylinder 252 is slidably sleeved on the outer cylinder 251, the second end 2522 of the inner cylinder 252 is rotatably coupled to the hinge assembly 260 by a pin 261, and the other end of the hinge assembly 260 is welded to the corresponding charging plate 200. . The two charging plates 200 can achieve a small range of rotation relative to the housing 240 by the hinge assembly 260. For example, a segment plate having a length of 1.5 m, the corresponding charging plate 200 can achieve a rotation of about 5° with respect to the housing 240.

The elastic member 253 is a spring, and the elastic member 253 is sleeved on the inner cylinder 252. One end of the elastic member 253 is positioned at the limiting portion 2511 of the outer cylinder 251, and the other end of the elastic member 253 is positioned on the hinge assembly 260.

The elastic member 253 is pressed against the outer cylinder 251. Since there may be a certain compression deviation caused by the different connection components 250 on the two charging boards 200, it is difficult to achieve synchronous compression deformation, so that the two charging boards 200 at the same position form a certain opening angle, and the hinge assembly 260 can make two The charging board 200 has a small angle of opening angle for smooth sliding. During the process in which the charging blade 10 is in contact with the two charging plates 200, the energy storage device of the rail vehicle communicates with the power source to charge the energy storage device.

After the charging blade 10 is quickly slid over the slot body 230, the charging blade 10 is disconnected from the electrical connection with the two charging plates 200, and the charging of the energy storage device of the rail vehicle is completed, and the elastic recovery of the two charging plates 200 at the corresponding elastic members 253 is resumed. Reset under force.

Thus, by providing the connection assembly 250 that moves relative to the housing 240, the charging assembly 200 can be supported and fixed to the housing 240 by the connection assembly 250. Moreover, the connection assembly 250 can drive the charging board 200 to move relative to the housing 240. Therefore, the clamping force of the two charging plates 200 to the charging blade 10 can be improved, thereby improving the reliability of electrically connecting the charging blade 10 and the charging slot assembly 20. Moreover, a rotatable hinge assembly 260 is disposed between the connection assembly 250 and the charging board 200. The hinge assembly 260 can buffer the impact of the charging knife 10 on the charging slot assembly 20, reducing the noise of the charging slot assembly 20, and extending the length. The service life of the charging trough assembly 20.
