Problems solved by technology

[0003] The main hinge and auxiliary hinge of the door hinge mechanism are mostly made of molds. In this way, eight kinds of molds are needed to produce a car, which leads to high mold cost. The corresponding different installation fixtures and different welding positioning also greatly increase the production cost.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0021] Such as Figure 3 to Figure 6 As shown, a door hinge mechanism for a vehicle includes a main hinge 21 for connecting the door, a secondary hinge 22 for connecting the vehicle body, and a pin shaft connecting the main hinge 21 and the secondary hinge 22 23. The main hinge 21 rotates around the pin shaft 23 relative to the secondary hinge 22; two mounting holes 24 are arranged on the secondary hinge 22, and the secondary hinge 22 is fixed on the vehicle body through the mounting holes 24; The main hinge 21 is a pair of first main hinge 211 and second main hinge 212 with the same structure; the secondary hinge 22 is a pair of first secondary hinge 221 and second secondary hinge 222 with the same structure. The first auxiliary hinge 221 and the second auxiliary hinge 222 manufacture the mounting holes; the pin shaft 23 is a pair of fi...

Abstract

The invention provides a door hinge mechanism used for vehicles, which comprises main hinges, auxiliary hinges and pin shafts connected with the main hinges and the auxiliary hinges. The main hinges rotate around the pin shafts relative to the auxiliary hinges; the auxiliary hinges are provided with two mounting holes; the main hinges comprise a first main hinge and a second main hinge which are similarly structured in pair; the auxiliary hinges comprise a first auxiliary hinge and a second auxiliary hinge which are similarly structured in pair; the pin shafts comprise a first pin shaft and asecond pin shaft which are similarly structured in pair, and a connecting line of the two mounting holes of the first auxiliary hinge and a connecting line of the two mounting holes of the second auxiliary hinge are all skewed with center lines of the corresponding pin shafts. The door hinge mechanism has the advantages that: the main hinges, the auxiliary hinges and the pin shafts are adopted asthe universal structure, and only the positions of the mounting holes on the auxiliary hinges are different,, so the versatility of the parts are improved, and the die cost, fixture cost and mountingand positioning cost are greatly reduced. Meanwhile, by adopting the skewed connecting lines of the upper two mounting holes and the lower two mounting holes, the door hinge mechanism improves the bearing capacity of the first hinges and the second hinges, thereby effectively preventing the vehicle door from sagging.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a door hinge mechanism for vehicles. 【Background technique】 [0002] The door hinge mechanism mainly makes the relative rotation between the car door and the body of the car. At present, for the door hinge mechanism of double-suspension vehicles, such as figure 1 and figure 2 As shown, it includes a main hinge 11 that is rigidly connected with the automobile door system, and a secondary hinge 12 that is rigidly connected with the vehicle body. Both the primary hinge 11 and the secondary hinge 12 have two connecting arms 13 that are parallel to each other. In the designed transfer hole 131, a pin shaft 14 passes through the middle, thereby connecting the door system and the vehicle body. This secondary hinge 12 is usually provided with two holes 121 for fixing the hinge mechanism on the vehicle body. In general, the single door of an automobile is provided wit...
