A bus door and door umbrella mechanism

Abstract

The invention discloses a novel bus door and bus door umbrella mechanism. The mechanism comprises a base, an arc door, an arc door pocket, a triangular top board, an arc door drive assembly, a left curtain board, a right curtain board, a curtain board drive assembly and an umbrella cloth unfolding assembly. The base is of a cavity structure. An arc trend semicircular groove is formed in a lower bottom board of the base. The arc door drive assembly comprises a first motor and a gear set. The arc door is arranged in the arc door pocket. The triangular top board is fixedly connected with the arc door pocket. The left curtain board is fixedly connected with a left rotating shaft, the right curtain board is fixedly connected with a right rotating shaft, and the curtain board drive assembly is arranged on the upper portion of the triangular top board. The umbrella cloth unfolding assembly comprises a drive assembly, a pulley sliding block assembly and a connecting rod assembly. Opening and closing of the door are designed into uniform motion of the motor, the situation that opening and closing power of an existing bus door is not uniform, and passengers in standing restricted zones are prone to be hurt is avoided, and the situation that passengers get wet in the rain when getting off to a bus station on rainy days is avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile doors, in particular, the invention relates to a bus door and a door umbrella mechanism. Background technique [0002] With the development of the urbanization process, the population of most cities has increased sharply, resulting in more and more people taking buses during the morning and evening peaks during work, often full of people on the bus, resulting in many passengers Standing in the standing restricted area. [0003] Many residents said that when taking the bus, they often encounter the following situation: due to the large number of people, when the passengers who have not had time to get off the bus have just walked to the standing restricted area of ​​the bus door, the driver has already pressed the bus door closing switch, and then the driver The master sees from the camera that there are passengers who have not got off the bus, and quickly presses the door open switch, so that ...

Problems solved by technology

[0003] Many residents said that when taking the bus, they often encounter the following situation: due to the large number of people, when the passengers who have not had time to get off the bus have just walked to the standing restricted area of ​​the bus door, the driver has already pressed the bus door closing switch, and then the driver The master sees from the camera that there are passengers who have not got off the bus, and quickly presses the door open switch, so that the doors of the bus that have not been closed are quickly opened again. Often the bus doors will be opened to those who are about to get off in the standing restricted area. Passengers, bring certain security risks

[0004] At present, the opening and closing of the bus door uses an anti-parallelogram mechanism. According to the principle of mechanism movement, the anti-parallelogram mechanism must have an active rotation axis, and due to the uneven power of the door opening and closing, it often produces relatively loud noises. At the same time, this active rotating shaft was basically exposed outside in the past, but now it is only covered by a shell, and then affixed with the words prohibiting climbing. It can grasp the active rotating shaft, which does not fundamentally solve the safety hazard in practical application
