Railway passenger train body

Abstract

The invention provides a railway passenger train body. The railway passenger train body comprises a passenger train body bottom plate and passenger train body side walls arranged at two sides of the passenger train body; a sliding door is arranged at a through port on one of the passenger train body side wall; the passenger train body bottom plate is covered with an interior floor board; and a first gap is formed between the internal floor board and the top surface of the passenger train body bottom plate; a pedal is arranged in the first gap; a gear mechanism is fixedly arranged between the pedal and the sliding door; the gear mechanism comprises a transmission shaft capable of being self rotated and a first gear and a second gear which are respectively fixedly arranged on the transmission shaft; a first rack extending along the longitudinal direction is fixedly arranged on the sliding door; a second rack extending along the horizontal direction is fixedly arranged on the pedal; the first gear is engaged with the first rack, the second gear is engaged with the second rack, so that the second gear which rotates along with the transmission shaft can drive the pedal to move towards the external side of the passenger train body bottom plate. According to the railway passenger trail body provided by the invention, the pedal can be stretched out when the sliding door is opened, the gap between the station and the passenger train body is blocked, and thus, the safety on a railway passenger train and the speed of the railway passenger train are improved.

Description

technical field [0001] The invention relates to railway vehicle manufacturing technology, in particular to a rail passenger car body. Background technique [0002] When the current rail passenger cars (including subway passenger cars, ground rail passenger cars, etc.) stop at the station, in order to ensure driving safety, a certain gap K (such as Figure 1A However, due to the existence of this gap, when the rail passenger car opens the side door of the car body for passengers to pass through, passengers can easily step on this gap unintentionally and cause danger. Passengers’ small items such as mobile phones and wallets may also be damaged. Falling into this gap will cause unnecessary losses. [0003] In the prior art, in order to avoid the above-mentioned gap from causing damage to the personal and property safety of passengers, the following measures are adopted, that is, when the rail passenger car is parked, after the door is opened, a transition pedal 1 is manually p...

Problems solved by technology

[0004] However, in the prior art, this method of manually placing transition pedals requires a large amount of manpower to be wasted, and affects the average running speed of the train, especially for subway passenger cars, which have many stops, a large passenger flow, and many doors. , this method is even more unusable in the prior art
