Passenger car side cabin door hinge structure

Abstract

The invention relates to a passenger car side cabin door hinge structure. The structure comprises hinge mounting channel steel which is fixed below a waist beam and has an L-shaped section, a side cabin door, and a single-shaft hinge of which the two ends are respectively connected with the hinge mounting channel steel and the side cabin door. The side cabin door comprises a cabin door sectional material located below the hinge mounting channel steel when the side cabin door is closed and a cabin door plate arranged at the upper end of the cabin door sectional material and used for being connected with the single-shaft hinge, and a sealing rubber strip used for abutting against the top end of the cabin door sectional material is further arranged at the lower end of the hinge mounting channel steel. Compared with the prior art, the cabin door sealing effect is good, the structure is simple, and the closing reliability of the side cabin door can be further improved.

Description

technical field [0001] The invention belongs to the technical field of key parts of automobiles, and relates to a hinge structure for a side cabin door of a passenger car. Background technique [0002] As an important part of the whole vehicle, the passenger car hatch plays a very important role. The main design difficulty of the hatch lies in the connection method of the hinge. The side hatch hinge of a bus is a body component used to swing and lift the side hatch, and its specific structure determines the opening angle of the hatch. The sealing performance and assembly process also determine the connection form between the lower edge of the side skin and the waist beam, and affect the appearance quality of the car body. Although the design structure and assembly process of the existing door hinges on passenger cars are relatively mature and can meet the basic requirements for use, the hinge itself has disadvantages such as large pre-tightening force, high material cost, p...

Problems solved by technology

In this patent, by setting the sealing rubber strip against the side of the hatch body, it also cooperates with the mounting plate to achieve a double effect of preventing rainwater penetration. However, since the sealing strip is against the side of the hatch body when closing, the sealant The bar will produce an outward opening reaction force on the door body due to its own elastic pressure. In this way, it is easy to cause the side door to be shaken open due to the vibration of the car body during the driving process of the bus.
