The charging blade assembly 100, the charging apparatus 800, and the rail vehicle according to the embodiment of the present invention are described below with reference to fig. 1 to 8.

As shown in fig. 1 to 4, according to the charging blade assembly 100 of the embodiment of the present invention, the charging blade assembly 100 includes: mounting bracket 10, swing arm 20, pivot shaft 30, bushing 40 and charging blade 50.

Specifically, as shown in fig. 1 and 2, the mounting bracket 10 is provided with a mounting hole 133, and the charging blade 50 is provided on the swing arm 20. The swing arm 20 is provided with a pivot hole 221 (as shown in fig. 5), the pivot shaft 30 is arranged in the assembly hole 133 through the pivot hole 221, and the swing arm 20 can rotate around the central axis of the pivot shaft 30. Thus, when the swing arm 20 rotates, the charging blade 50 can be driven to rotate.

For example, when the charging blade 50 and the charging slot 810 have a deviation angle due to an assembly error, the charging blade 50 may be rotated to a position opposite to the charging slot 810 by the swing arm 20. Therefore, the charging blade 50 can be opposite to the charging groove 810, and when the charging blade 50 extends into the charging groove 810 to be charged, the charging blade 50 can be in surface-to-surface contact with the charging groove 810, so that the current receiving stability of the charging blade 50 is improved, and the charging efficiency of the railway vehicle is improved.

In addition, when the charging blade 50 swings left and right along with the rail vehicle (in the left and right directions as shown in fig. 2 and 4) during the running of the vehicle, the charging blade 50 can rotate left and right through the swing arm 20, so that the charging blade 50 and the charging slot 810 can always keep surface-to-surface contact, and the stability and reliability of the charging of the rail vehicle are improved.

As shown in fig. 4 and 6, the bushing 40 includes an annular elastic member 420, the elastic member 420 is elastically deformable, the bushing 40 is fitted over the pivot shaft 30 and positioned in the pivot hole 221, and the bushing 40 is in contact with the inner wall of the pivot hole 221.

It should be noted that, by providing the bushing 40, when the charging blade 50 and the charging slot 810 are misaligned due to an assembly error, the charging blade 50 can press the elastic member 420 of the bushing 40 to elastically deform through the swing arm 20, so as to adjust the alignment of the charging blade 50 and the charging slot 810. Moreover, when the charging blade 50 swings left and right, the bushing 40 with the elastic member 420 can absorb the impact on the charging blade 50, thereby improving the structural stability of the charging blade assembly 100 and reducing the charging noise of the rail vehicle.

In addition, the elastic member 420 may also absorb and buffer the impact of the charging blade 50 in the up-down direction and the front-rear direction. For example, when the charging blade 50 is impacted in the vertical direction and moves in the vertical direction with respect to the mounting bracket 10, the charging blade 50 may press the elastic member 420 to be elastically deformed. Therefore, the impact in the vertical direction on the charging blade 50 can be converted into the elastic potential energy of the elastic member 420, and the impact noise of the charging blade assembly 100 is effectively reduced. Similarly, when the charging blade 50 is impacted in the front-back direction, under the elastic force of the elastic member 420, the charging blade 50 can press the elastic member 420 and rotate in a vertical plane in a small range in the front-back direction, the elastic member 420 can effectively buffer and absorb the impact on the charging blade 50, the impact noise of the charging blade assembly 100 is reduced, and the problems that the charging blade 50 is not aligned to the charging slot 810 and the contact is poor are effectively solved.

According to the charging blade assembly 100 of the embodiment of the present invention, by disposing the charging blade 50 on the swing arm 20, the charging blade 50 can rotate about the pivot shaft 30 with the swing arm 20. Therefore, the problem that the charging blade 50 is not aligned with the charging slot 810 due to assembly errors of the charging blade 50 and the charging slot 810 can be solved by rotating the charging blade 50. Moreover, in the running process of the railway vehicle, when the charging blade 50 swings left and right along with the railway vehicle, the charging blade 50 can be correspondingly rotated and adjusted through the pivot shaft 30, so that the charging blade 50 and the charging groove 810 are always in surface-to-surface contact, and therefore, the stability of the current collection of the charging blade 50 is improved, and the charging efficiency of the railway vehicle is improved.

It should be noted that the swing arm 20 and the charging blade 50 may be integrally formed, so that the charging blade assembly 100 is convenient to process and manufacture, and the production cost of the charging blade assembly 100 can be reduced. The swing arm 20 and the charging blade 50 may also be two separate components. It will be appreciated that when the swing arm 20 and charging blade 50 are formed of two separate parts, the charging blade 50 functions primarily to conduct electricity, while the swing arm 20 functions primarily to secure the assembly.
