DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model discloses an evacuation pedal device for a rail transit urban vehicle, comprising a sliding frame 1, a pedal 7, and a connecting frame 12; the connecting frame 12 is assembled on the sliding frame 1 through a roller group 13, the pedal 7 is connected to the sliding frame 1 through a pin 16, a connecting rod 1 5, and a connecting rod 2 6, the pedal 7 is connected to the connecting frame 12 through a pin 16 and a gas spring 4, and the pedal 7 is connected to a cam 15; the sliding frame 1 is connected to one end of a steel wire rope 1 3, and the other end of the steel wire rope 3 is connected to the cam 15; the sliding frame 1 is connected to one end of a steel wire rope 2 8, and the other end of the steel wire rope 2 8 is connected to the pedal 7 after passing through a pulley 17.

[0023] The sliding frame 1 of the present invention is connected to the vehicle body via bolts. The sliding frame 1 is equipped with a mechanical lock assembly 2. Several sets of synchronous pulleys 9 and synchronous belts 10 are installed on the sliding frame 1. These synchronous pulleys 9 and synchronous belts 10 are arranged parallel to each other and are driven by a motor 11. A baffle 14 is provided on the side of the connecting rod 5. The vehicle body is a rail transit vehicle, and the sliding frame 1 is mounted on the passenger compartment door of the vehicle body.

[0024] The usage process is as follows: when unfolding, the mechanical lock assembly 2 is unlocked by electric or manual operation, and the synchronous belt 10 is driven by the motor 11 to be pushed out to the extended state; at the same time, the gas spring 4 and the baffle 14 push the pedal 7 to the use state; when retracting, the steel wire rope 8 pulls the pedal 7 back by electric or manual operation, and the connecting frame 12 runs under the pull of the synchronous belt 10, and automatically locks the pedal after colliding with the mechanical lock assembly 2.

[0025] The main body of the utility model belongs to a multi-link design scheme, which meets the functions of translation, lifting and telescopic. The built-in six-link structure meets the up and down telescopic movement of the pedal. With a mechanical lock assembly, after it is recovered into place, the pedal assembly is locked by the mechanical lock. When the urban bus evacuation pedal device is opened, the mechanical lock is unlocked electrically, and then the motor drives the synchronous belt to push the sliding frame out, and the pedal is opened at the same time by the baffle and gas spring. It is equipped with an emergency unlocking device, which is connected to the mechanical lock assembly through an electromagnet and a steel wire rope, respectively, and can be unlocked by electric or manual operation.
