Abstract

The invention relates to a sealing structure of a bus hinge cabin door. The side cabin door (5) is hinged to a bus body skeleton (1) through a cabin door hinge (2). An air brace (4) is further arranged on the bus body skeleton (1) in a hinged mode. The other end of the air brace (4) supports the side cabin door (5) in a hinged mode. During working, the air brace (4) drives the side cabin door (5)in a telescopic mode to be opened or closed. The sealing structure comprises a sealing seam allowance (6) located below the cabin door hinge (2) and having the section in an L shape. The edge part ofthe sealing seam allowance (6) is connected with the inner edge of the bus body skeleton (1) in a sealed mode to form a sealed seam allowance groove with the two sides being open. Compared with the prior art, the sealing structure of the bus hinge cabin door continues the structural strength of the iron cabin door hinge, has reliable sealing performance, and is simple in structure, convenient to operate, low in cost, high in generality and the like.

Description

technical field [0001] The invention relates to a side hatch of a passenger car, in particular to a sealing structure for a hinged hatch of a passenger car. Background technique [0002] At present, passenger cars at home and abroad generally have the basic configuration requirements for side hatches. The side hatches of the flip hinge structure account for the majority, and the flip hinge structure side hatches are divided into rubber hinge structure side hatches and iron hinge side hatches. In general, rubber hinged side hatches have relatively good airtightness, but the rubber is prone to aging, and even the door falls off; iron hinged side hatches have good strength, but most of them are not well sealed, and water and ash leaks are always present. is a big problem. As a manufacturer of passenger cars, it has always been the long-cherished wish of all employees of the company to produce products that satisfy customers. Contents of the invention [0003] The object of...
