As shown in fig. 14, both ends of the fixing beam 230 are open, and one side wall of the fixing beam 230 is open and penetrates both ends to form a fixing groove 231, as shown in fig. 14 and 15, one end of the bolt 240 extends into the fixing beam 230 from the fixing groove 231 and is stopped by the inner wall of the fixing beam 230, so that the bolt 240 cannot be drawn out in the radial direction of the fixing beam 230, and a portion of the bolt 240 extending out of the fixing beam 230 may be connected to the fixing base 220.

As shown in fig. 11, the side wall of the fixing base 220 is provided with a waist-shaped hole 228, and a portion of the bolt 240 extending out of the fixing beam 230 can penetrate through the waist-shaped hole 228 to be connected with the fixing base 220, so that the fixing base 220 and the fixing beam 230 can be fixedly connected into a whole through the bolt 240, thereby ensuring the stable structure of the fixing base 220, ensuring the stable installation environment of the flow teaching piece 210, avoiding the flow teaching piece 210 from shaking in the process of contacting with the flow taking piece 140, and improving the safety and accuracy of flow teaching.

As shown in fig. 7-11, the side of the holder 220 facing into the track has a guide ramp 227, so that the thickness of the end of the fixing base 220 close to the flow teaching member 210 to the end away from the flow teaching member 210 is gradually reduced, as shown in fig. 7, the thickness of both ends of the holder 220 is smaller than that of the middle portion of the holder 220, and thus, after the rail vehicle arrives at a station, the flow taking part 140 is firstly contacted with the end part of the fixed seat 220, and as the thickness of the fixed seat 220 from the end part to the middle part is gradually increased, the contact pressure of the flow taking part 140 and the fixed seat 220 is gradually increased, and when the fluid taking element 140 is completely aligned with the fluid delivering element 210, the elastic force of the elastic element 130 in the fluid taking device 100 reaches the maximum, at this time, the pre-tightening force of the elastic element 130 driving the fluid taking element 140 toward the fluid delivering element 210 is the maximum, therefore, the current taking element 140 can be effectively contacted with the current teaching element 210, and the current transmission of the current taking element and the current teaching element is more stable.

Thus, the contact pressure between the fluid taking member 140 and the fluid dispensing device 200 is gradually increased during the contact process, and the contact pressure is gradually decreased again when the charging is finished and the device leaves the station. In the process, the flow taking part 140 does not rigidly collide with the fixing seat 220 and the flow teaching part 210, so that the structure of the flow teaching device 200 can be prevented from being damaged in the charging process, and the flow teaching process can be safely carried out.

According to the current teaching device 200 of the embodiment of the present application, the current teaching device 200 has the guiding slope 227, when the rail vehicle enters the station, the current taking part 140 is gradually electrically connected with the current teaching part 210 of the current teaching device 200 along the guiding slope 227, and the contact pressure between the current taking part 140 and the current teaching part 210 is gradually increased and then gradually reduced, so that the rigid collision between the current teaching part 210, the current taking part 140 and the fixed seat 220 can not occur, the current teaching process is safe and reliable, and the current teaching device 200 has a simple structure and is convenient to install.

In some embodiments, as shown in fig. 8 and 9, the fixing base 220 includes: a first fixing seat 221 and a second fixing seat 222.

As shown in fig. 8, the guiding slope 227 of the first fixing seat 221 and the guiding slope 227 of the second fixing seat 222 are both disposed on one side facing the inside of the track, so that, in the process of contacting the fluid-taking member 140 with the fluid-dispensing device 200, the first fixing seat 221 and the second fixing seat 222 do not rigidly collide with the fluid-taking member 140, and the fluid-dispensing process is safe and reliable.

As shown in fig. 8 and 9, the mounting position is disposed at the side of the end surface close to the guide slope 227, that is, the insertion groove is disposed adjacent to the side of the first fixing seat 221 or the second fixing seat 222 facing the inside of the rail, so that after the flow-directing member 210 is mounted in the insertion groove, one side of the flow-directing member 210 faces the inside of the rail, and as shown in fig. 8, the side of the flow-directing member 210 facing the inside of the rail is flush with the side of the first fixing seat 221 or the side of the second fixing seat 222, so that the entire flow-directing device 200 faces the side of the inside of the rail, and thus, when the flow-directing member 140 contacts the flow-directing device 200, the flow-directing member 140 can smoothly move along the side of the flow-directing device 200 without rigid collision.

Wherein, the flow-teaching piece 210 at least partially protrudes to the direction close to the inner side of the track, so that when the flow-taking piece 140 contacts with the flow-teaching device 200, the protruding part of the flow-teaching piece 210 has larger contact pressure with the flow-taking piece 140, the contact of the two is more stable, the condition of poor contact or power failure does not occur, and the reliability and the effectiveness can be ensured.

If the current teaching piece 210 is arc-shaped, and the middle part of the current teaching piece 210 protrudes to the direction close to the inner side of the track, therefore, the current taking piece 140 moves along the arc edge of the current teaching piece 210, so that when the middle parts of the current taking piece 140 and the current teaching piece 210 are aligned, the contact pressure between the middle part of the current teaching piece 210 and the current taking piece 140 is the largest, the contact is more stable and reliable, and the effect of safe charging is realized.
