Technical Field

The utility model relates to a bus passenger protection device field specifically is a prevent passenger and fall down device for bus.

Background

The bus is provided with a plurality of stations except for seats, standing passengers are easy to stand unstably and fall down when emergency braking or too fast starting speed occurs to the bus, at present, only handrails and hanging rings are arranged on the bus to ensure the safety of the passengers, and some passengers, especially old people and children, are easy to fall down, so that the study of a device for passively protecting the passengers is particularly important.

Disclosure of Invention

The utility model aims at providing a prevent passenger's device of falling down for solving the bus problem that the passenger easily fell down when emergency braking on the bus.

The utility model has the following concrete scheme: the utility model provides a prevent passenger and fall down device for bus, including a plurality of safety belts of arranging along carriage length direction, the safety belt both ends are fixed at carriage both sides lateral wall face, one of them lateral wall is equipped with fixed sleeve, fixed sleeve is equipped with one and follows the slide bar that carriage length direction arranged, the end fixing that corresponds every safety belt on the carriage lateral wall that is located slide bar one side is equipped with a support ring that outwards stretches out, the safety belt pass behind the support ring with slide bar fixed connection again with carriage lateral wall fixed connection, the carriage lateral wall is located slide bar top or below and is equipped with a cylinder, the cylinder passes through bus owner's accuse platform control, be connected through the connecting rod between the piston rod of cylinder and the slide bar, two elastic components are equipped with on the every safety belt, elastic component top.

The elastic piece of the utility model is a rubber band or a spring.

The height between the fixed points at the two ends of the safety belt and the bottom plate of the carriage is 0.9-1.4 m.

The distance between every two safety belts of the utility model is 25-50 cm.

Cylinder control valve and door control valve pass through the time delay unit linkage, and the door is closed the back and is stretched out through a period of time cylinder control valve action control cylinder piston rod, and the safety belt is by the decline of tightening in order to protect the passenger, and the cylinder withdrawal when the door is opened, the elastic component is received the safety belt to the roof so that the passenger walks about in the carriage and gets on or off the bus.

The utility model discloses the theory of operation as follows: when the cylinder retracts, the safety belt is received by the two pigeon elastic pieces, the top of the vehicle is higher than the height of a common person, a passenger can walk freely below the vehicle, after the vehicle door is closed, the piston rod of the cylinder is controlled to stretch out to drive the slide rod to slide forwards before the vehicle starts, the middle of the safety belt is fixedly connected with the slide rod, two ends of the safety belt are fixedly connected with the compartment wall, the length of the safety belt between the support ring and the compartment side wall is shortened when the slide rod slides, the two elastic pieces are pulled downwards by the safety belt, so that the height of the safety belt is reduced to protect the passenger, and one safety belt is arranged in the compartment at intervals from front to back.

Compared with the prior art, the utility model has the following advantages: 1. the safety belt is used as a passive protection device to strengthen the protection of passengers, and the passengers can not be blocked when the passengers need to walk on or off the bus; 2. the air cylinder control valve is arranged to be linked with the vehicle door, so that the driver can control the air cylinder conveniently.

Detailed Description

Referring to fig. 1-5, the embodiment includes five safety belts 6 arranged along the length direction of the carriage, two ends of each safety belt 6 are fixed on two side wall surfaces of the carriage, one side wall 1 of each safety belt 6 is provided with six fixing sleeves 3, each fixing sleeve 3 is internally provided with a slide bar 3 arranged along the length direction of the carriage, the end part of each safety belt 6 corresponding to the side wall 1 of the carriage on one side of the slide bar 3 is fixedly provided with a support ring 5 extending outwards, the safety belt 6 penetrates through the middle of the support ring 5 and is fixedly connected with the slide bar 3, the end part is fixedly connected with the side wall 1 of the carriage, the side wall 1 of the carriage is provided with a cylinder 4 below the slide bar 3, the cylinder 4 is controlled by a bus master control console, a piston rod of the cylinder 4 is connected with the slide bar 3 by a connecting rod 10, two elastic members 7 are arranged on, when a piston rod of the cylinder 4 is in a retraction state, the two elastic pieces 7 receive the safety belt 6 to the bottom of a carriage top cover 8, at the moment, the middle tightening section of the safety belt 6 is about 2m away from a carriage bottom plate 9, a passenger can freely pass under the safety belt 6, when the piston rod of the cylinder 4 extends out, the slide rod 3 is driven to slide forwards, the slide rod drives fixing points of all the safety belts 6 to synchronously move forwards, so that the safety belt 6 is long in the total length from the support ring 5 to the fixing points and then to the fixing points of the carriage side walls 1, the length from the support ring 5 to the other side wall 1 is shortened, the elastic pieces 7 are pulled downwards by the safety belt 6, the safety belt 6 is in an almost horizontal state, at the moment, about 1.3m of the height of the safety belt 6 away from.

The elastic 7 pieces in this embodiment are rubber bands.

The distance between every two safety belts is 30cm in the embodiment.

In the embodiment, the cylinder 4 control valve and the vehicle door control valve are linked through a time delay device to realize one-key control of the vehicle door and the safety belt by a driver, the piston rod of the cylinder 4 is controlled to extend out by the action of the cylinder 4 control valve after the vehicle door is closed for 20 seconds (for passengers to walk and get on or off the vehicle in the period of time), the safety belt 6 is tightened and descended to protect the passengers, the cylinder 4 retracts when the vehicle door is opened, and the safety belt is retracted towards the vehicle roof by the elastic piece 7 so that the passengers walk to get on or off the vehicle.
