Problems solved by technology

[0002] At present, the hidden door hinge uses an outer spring hinge. The disadvantages of this hinge are: the outer spring is easy to jump off and hurt people; the hinge cup is made of plastic injection molding, which is not firm; when the door is closed, it will hit , prone to danger; the aging of the hinge cup greatly affects its service life
Later, the inner spring hinge was developed, which avoided the problem of spring jumping off, but still did not solve the impact generated when closing the door.

Abstract

The invention relates to a novel four-link hinge assembly, which is used for connecting a car body with a car door. The hinge assembly comprises a connecting plate, a four-link hinge movable plate, a first lining rod, a second lining rod, a hinge fixed plate and a fixed plate baffle. The connecting plate is welded on the side wall stand column of the car body. The four-link hinge movable plate is connected with the connecting plate. One ends of the first lining rod and the second lining rod are movably connected with the four-link hinge movable plate. The other ends of the first lining rod and the second lining rod are movably connected with the hinge fixed plate. The hinge fixed plate is connected with the fixed plate baffle. The hinge fixed plate is fixedly connected with the car door through bolts. Compared with the prior art, the novel four-link hinge assembly has the advantages of simple structure, large opening angle, high firmness and durability, no impact, small friction, long service life and the like.

Description

technical field [0001] The invention relates to a novel four-link hinge assembly, in particular to a novel four-link hinge assembly. Background technique [0002] At present, the hidden door hinge uses an outer spring hinge. The disadvantages of this hinge are: the outer spring is easy to jump off and hurt people; the hinge cup is made of plastic injection molding, which is not firm; when the door is closed, it will hit , prone to danger; the aging of the hinge cup greatly affects its service life. Later, the inner spring hinge was developed again, which avoided the problem of spring jumping off, but still did not solve the impact generated when closing the door. In recent years, a two-stage force hinge has been developed, and the hinge cup is made of steel or alloy. The two-stage power hinge completely avoids the disadvantages of the spring jumping off and the impact when the door is closed, and can stop at any position. Only when it is closed to the last 45°, the spring ...
