[0003] In the prior art, actual demonstration training is conducted using real electric buses. In order not to affect normal operation, training can only be conducted during the rest time of the electric buses. However, since many trainees need to be trained and each person needs to perform multiple exercises during training, it takes a lot of time to conduct training, which is difficult to coordinate and very inconvenient. Therefore, a special training facility is urgently needed. Summary of the invention

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-3 As shown, the electric passenger car collector shoe teaching platform described in the present invention includes a base 1, a working platform 2, a collector shoe assembly 3, a contact rail 4, a lifting rod 5, a simulation platform 6, a mounting bracket 7 and a display device 8; wherein, the working platform is installed above the base, and the collector shoe assembly is installed on one side of the base; the mounting bracket is fixed to one side of the working platform, on the same side as the collector shoe, the contact rail is fixed to the bottom of the mounting bracket, and contacts with the collector shoe in the collector shoe assembly, and the display device is installed on the working platform, and is electrically connected to the collector shoe in the collector shoe assembly.

[0029] For the convenience of going up and down, a walking ladder 21 is also provided on one side of the working platform, and a safety guardrail 22 is also provided on the side of the working platform to prevent falling accidents. A retractable support foot 11 and a movable universal wheel 12 are also provided at the bottom of the base to facilitate the adjustment of the platform height and the movement of the entire platform.

[0030] In actual operation, a scrapped collector shoe assembly is used, which includes a collector shoe, a bogie, a base, a swing arm, a locking mechanism, and a cable. The collector shoe can move laterally and has at least three moving gears; the swing arm 31 is the operating object of the recovery rod and contacts the contact rail. One end of the recovery rod is a straight rod and the other end is a hook.

[0031] like Figure 2 As shown, the specific structure of the mounting bracket 7 is: it includes an L-shaped support frame 71, a support rod 72, a top beam 73, a bottom beam 74 and a connecting rod 75. The two L-shaped support frames are fixed in parallel on the same side of the working platform. A top beam is fixed on the top of the L-shaped support frame. The simulation platform is hinged to the top beam. The support rod is installed on the horizontal part of the L-shaped support frame and is parallel to the vertical part of the L-shaped support frame. When the simulation platform is in a horizontal state, it is supported by the L-shaped support frame, the top beam and the support rod. The connecting rod is fixed to the horizontal part of the L-shaped support frame. A bottom beam is fixed between the two connecting rods, and the contact rail is fixed on the bottom beam.

[0032] The simulation platform is hinged to the top of the mounting bracket, and has two states: horizontal and vertical, so that the teaching platform of the present invention can simulate two operation modes: the collector shoe is located on the platform side and the collector shoe is located on the non-platform side. When the simulation platform is flipped to a vertical state, training and operation under non-platform conditions can be carried out; after the simulation platform is flipped and laid flat, training and operation under simulated platform conditions can be carried out. In the horizontal state, the simulation platform is on the same level as the working platform and is 8-12 cm away from the working platform to facilitate the insertion of the recovery rod.

[0033] like Figure 3 As shown, during the simulation training, the operator stands on the simulation platform and the working platform, passes the lifting rod through the gap between the simulation platform and the working platform, performs a simulated operation on the collector shoe, and presses down or hooks up the swing arm of the collector shoe. The result of the operation (success or failure) and the operation time are displayed on the display device.

[0034] In order to prevent slipping, all standing areas, especially working platforms and simulation platforms, are covered with anti-slip steel gratings.
