A side-opening hatch door structure of a city bus

Abstract

The invention discloses a side-opening type cabin door structure of a city bus, comprising a cabin door body, a hinge, a sealing strip, a cushion plate and an air spring, wherein the hinge is installed on the cabin door body, a fixing bracket is arranged on the back of the hinge, the fixing bracket is welded on a vehicle body, and the fixing bracket is a hinge fixing bracket. The utility model hasthe advantages that the hinge is used as the rotation center of the hatch body, thereby realizing the side opening mode of the hatch door and facilitating the installation and maintenance of the components in the hatch; A lock, a pull handle and a gas spring are mounted on that hatch body, the function of the lock is to control the locking of the front and rear open door bodies, the pull handle is used to facilitate the opening of the hatch body, The function of the air spring is to facilitate the opening of the hatch door body. After the hatch door body is opened at a certain angle, the hatch door body is opened slowly under the action of the air spring, so that the opening process is semi-automated, thus embodying the humanized design. The structure is firm and durable, has good socialbenefits, and is suitable for popularizing and using.

Description

Technical field [0001] The invention relates to a cabin door structure, in particular to a side-opening cabin door structure of a city bus, belonging to the technical field of cabin door structure application. Background technique [0002] At present, the country vigorously advocates energy conservation and emission reduction, and domestic pure electric buses and hybrid electric buses and other new energy buses are becoming more popular, and the scope of application is gradually expanding and the geographical scope is wider. All or a larger part of the working energy of pure electric and hybrid buses is powered by batteries installed in the battery compartment. [0003] With the increasing requirements for the driving range of passenger cars, in addition to increasing the battery density, it is also necessary to increase the battery power capacity, that is, the size of the battery becomes larger, and the larger the size of the battery takes up more and more cabin space As a result...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the space in the cabin occupied by the battery with larger size is getting larger and larger, which makes it more and more inconvenient to install the parts in the cabin, and the existing passenger car cabin door structure cannot meet the needs of the cabin door. Under the condition of sealing performance, each structure and accessories of the cabin door can be reduced in size as much as possible, the net space in the cabin is relatively low, and the existing cabin door structure has poor sealing performance. In order to solve the problem that the process is not humanized enough, a side-opening hatch structure for city buses is proposed
