One of the two adjacent segment plates is provided with a first extending plate, the other one is provided with a second extending plate arranged at intervals, the first extending plate and the second extending plate are both arranged in a camber manner, and the camber angles of the first extending plate and the second extending plate are consistent with the camber angles of the two charging plates 200 at the inlet end 231 and the outlet end 232. The ends of the first extension plate and the second extension plate towards each other extend, the first extension plate extends into the second extension plate, and a gap of 2 mm-5 mm is formed between the first extension plate and the second extension plate so that the adjacent two section plates can be movably connected.
As shown in fig. 2, the connection assembly 250 includes: an outer cylinder, an inner cylinder 252 and an elastic member 253. The outer cylinder is an insulating part. The first end 2521 of the inner cylinder 252 is slidably received within the outer cylinder. A stopper 2523 that stops the end of the outer cylinder 253 is provided at the first end 2521 of the inner cylinder 252, and a buffer 2524 is provided between the stopper 2523 and the end of the outer cylinder 253. A second end 2522 of the inner tube 252 is rotatably coupled to the hinge assembly 260 by a pin, and the other end of the hinge assembly 260 is welded to the corresponding charging pad 200. Two charging plates 200 may be rotated relative to housing 240 through a hinge assembly 260 to a small extent. For example, a segment plate with a length of 1.5m, the corresponding charging plate 200 can rotate about 5 ° relative to the housing 240.
The elastic member 253 is a spring, the elastic member 253 is sleeved on the inner cylinder 252, one end of the elastic member 253 is positioned on the outer cylinder, and the other end of the elastic member 253 is positioned on the hinge assembly 260.
The housing 240 has a telescopic hole, and the first end 2521 of the inner cylinder 252 passes through the telescopic hole and is sleeved inside the shield 280. The protective cover 280 is an insulating member to improve the insulating protection effect of the charging chute assembly 20.
It should be noted that, along with the running of the rail vehicle, when the charging blade 10 enters the slot body 230, the charging blade 10 stops abutting against the two charging plates 200 to move towards a direction away from each other, and the two charging plates 200 drive the corresponding inner cylinder 252 to move relative to the outer cylinder, and press the elastic member 253. Since there may be a certain compression deviation due to the difficulty of synchronous compression deformation of the different connection assemblies 250 on the two charging plates 200, so that the two charging plates 200 at the same position form a certain opening angle, the hinge assembly 260 may allow the two charging plates 200 to have a small opening angle for smooth sliding. In the process that the charging blade 10 is in contact with the two charging plates 200, the energy storage device of the rail vehicle is communicated with a power supply to charge the energy storage device.
After the charging blade 10 slides through the slot 230 quickly, the two charging plates 200 are reset under the elastic restoring force of the corresponding elastic member 253, the stopping portion 2523 of the first end 2521 of the inner cylinder 252 stops against the end portion of the outer cylinder 251 to limit the moving distance of the inner cylinder 252, so that the two charging plates 200 can be prevented from colliding, and the two charging plates 200 can be kept in a gap to avoid the generation of the collision sound. The buffer member 2524 buffers and absorbs the collision between the inner tube 252 and the outer tube 251, thereby further reducing the operational noise of the charging chute assembly 20.
Thus, by providing the stopper 2523 on the housing 240 or the inner tube 252, the stopper 2523 can stop and limit the displacement of the inner tube 252 with respect to the housing 240, so that the two charging plates 200 can be prevented from colliding, and noise of the charging slot assembly 20 can be reduced. Also, the buffer member 2524 can buffer and absorb the collision between the inner tube 252 and the housing 240, thereby further reducing the operation noise of the charging chute assembly 20 and improving the stability and reliability of the charging chute assembly 20 in operation.
