Problems solved by technology

For the existing torsion spring type opening system, when the trunk lid is opened and closed, the hinge movable arm 5 generates frictional torque on the hinge base 7 to resist the rapid opening and fast closing of the trunk lid under the action of the torsion spring, But the articulation structure of existing hinge movable arm 5 and hinge base 7 can't produce enough big frictional torque, thereby makes the trunk lid easy to occur fast opening and fast closing under torsion spring action, thereby brings danger

Embodiment Construction

[0015] Figure 4 shows a hinged device according to the invention for figure 2 and image 3 The trunk opening system of the indirect torsion spring type and the trunk opening system of the direct torsion spring type are shown. Figure 4 The hinge device comprises a hinge shaft skeleton 12 arranged at the end of the gooseneck-shaped hinge movable arm 5 and a hinge base 7 hingedly connected to the hinge shaft skeleton 12 . The hinge shaft skeleton 12 has a cross-section that is an I-shaped annular shape, and has a central through hole in its center, such as Figure 5A As shown, the hinge base 7 includes a base housing 15 integrally formed with the rear bulkhead of the vehicle. There are openings on both side walls of the base housing 15, and the opening communicates with the central through hole of the hinge shaft skeleton 12. . The hinge base 7 also includes an annular sleeve 11 arranged between one side of the hinge shaft skeleton 12 and the side wall of the base housing ...

Abstract

The invention provides a hinge device for a vehicle trunk opening system. The hinge device comprises a hinge shaft frame arranged at the end part of a hinge moving arm, wherein the hinge shaft frame has a center through hole, and a hinge base hinged to the hinge shaft frame; the hinge shaft frame has an annular shape with an I-shaped section; the hinge base further comprises an annular sleeve arranged between the two sides of the hinge shaft frame and the side wall of the base shell; the annular sleeve and the I-shaped upper part of the hinge shaft frame are joined through an annular outer bushing; and the annular sleeve and the I-shaped lower part of the hinge shaft frame are joined through an annular inner bushing.

Description

technical field [0001] The present invention relates to a hinge device for installing a trunk opening system of a vehicle, in particular to a hinge device for a torsion spring type trunk opening system of a vehicle. Background technique [0002] In existing vehicles such as figure 1 As shown, one end of the hinge 4 is installed on the rear bulkhead 3 in the rear side body 1 of the vehicle, and the other end of the hinge 4 is installed on the trunk lid 2 . The hinge is mounted on the hinge base 7 of the rear bulkhead 3 . There are four types of hinge opening systems: spring, gas spring, spring and gas spring, and torsion spring. Torsion springs are divided into indirect torsion springs and direct torsion springs. figure 2 The opening system of the shown indirect torsion spring type, wherein one end of the torsion spring 8 is a U-shaped end so as to be able to be installed on the hinge bracket 6 of the hinge movable arm 5 of the opening system, and the other end of the tor...
