Turnover-rising hidden seat for rail vehicle

Abstract

A turnover-rising hidden seat for a rail vehicle comprises a shell, a cushion assembly, swing arms, damping springs and a full-length shaft. The shell is mounted in the side wall of a vehicle body; the cushion assembly comprises a cushion skeleton and a cushion and is mounted in a square frame of the shell, the full-length shaft is arranged inside the rear side of the cushion assembly, and the middle rear portions of the two sides of the cushion assembly are in hinged connection with the swing arms; each swing arm is in a < shape, one ends of the swing arms are in hinged connection with the cushion assembly, and the other ends of the swing arms are in hinged connection with the inner side surface of the shell; one ends of the damping springs are mounted in a groove in the outer side of theshell through ball joint connectors and can rotate around fixed points, and the other ends of the damping springs are arranged on the full-length shaft in a sleeving mode through damping spring connectors and can rotate around the full-length shaft; and the full-length shaft is mounted inside the rear side of the cushion skeleton, and the two sides of the full-length shaft penetrate through the damping spring connectors, gears and fixed seats sequentially. The cushion assembly overall rises while being turned over outwards, so that the turnover-rising hidden seat rises by the height of the cushion assembly in use in the space with the limited height, and accordingly, the turnover-rising hidden seat conforms to ergonomics; and the turnover-rising hidden seat can be hidden completely so asto save the space.

Description

technical field [0001] The invention relates to the field of railway train seats, in particular to a flip-up hidden seat for rail vehicles. Background technique [0002] At present, major cities in China are developing rail transit in order to solve the current traffic jams encountered in the city, because the transportation capacity and speed of rail transit have been greatly improved compared with automobiles, and the interior volume of existing rail passenger cars is fixed, and subways and light rail seats The chairs are basically fixed seats and manual folding seats, which occupy a large area in the compartment, and the number of passengers in the compartment is limited by the seats, which makes it impossible to carry more passengers during the peak hours of commuting and commuting. Or the unfolded state is controlled by passengers, and space cannot be vacated during the peak period of the flow of people, and the passenger capacity is low. [0003] However, the existing...

Problems solved by technology

[0002] At present, major cities in China are developing rail transit in order to solve the current traffic jams encountered in the city, because the transportation capacity and speed of rail transit have been greatly improved compared with automobiles, and the interior volume of existing rail passenger cars is fixed, and subways and light rail seats The chairs are basically fixed seats and manual folding seats, which occupy a large area in the compartment, and the number of passengers in the compartment is limited by the seats, which makes it impossible to carry more passengers during the peak hours of commuting and commuting. Or the unfolded state is controlled by passengers, and no space can be vacated during the peak flow of people, and the passenger capacity is low

[0003] However, the existing flip seat of rail vehicles can only be turned over, and the seat cushion cannot be raised, so it cannot reach a comfortable ergonomic height in a height-limited space; and the seat protrudes outside the side wall to occupy the outer space, which is inconvenient for passengers to move around. For example: the patent CN 104802814 B previously applied by the company discloses a flip seat for a railway car, including a seat and a backrest. Both sides of the backrest are provided with connecting sheet metal, and an arc-shaped chute is arranged inside the connecting sheet metal. The seat and the chute are movably connected by the rotating shaft, and the turning of the seat is realized through the movement of the rotating shaft in the chute, which simply realizes the turning up of the seat.
