An opening and holding device for a trunk lid of a vehicle

Abstract

The invention provides an open keeping device used for a trunk lid of a car. The open keeping device comprises a hinge base, movable hinge arms, hinge shafts, linings, sleeves and a limiting device, wherein the hinge base is installed on a back partition plate of a back car body of the car; one end of each movable hinge arm is hinged to the hinge base, and the other end of each movable hinge arm is connected to the trunk lid of the car; the hinge shafts are fixedly connected to the two side walls of the hinge base; each lining is fixedly arranged on the corresponding hinge shaft; each sleeve is installed on the outer side of the corresponding lining in a sliding mode; each movable hinge arm is fixedly connected with the corresponding sleeve; each sleeve rotates relative to the corresponding lining along with rotation of the corresponding movable hinge arm; the limiting device is arranged inside the hinge base; the limiting device is in friction fit and shape fit with the outer surfaces of the sleeves so that the trunk lid can be kept in an open position.

Description

technical field [0001] The invention relates to an opening and holding device for a trunk lid of a vehicle, in particular to a friction holding device for an opening hinge of a trunk lid 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 4 is mounted on the hinge base 5 of the rear bulkhead 3 . For the existing trunk lid opening system, when the trunk lid is opened and closed, the gooseneck-shaped hinge movable arm 6 generates frictional torque on the hinge base 5 to resist the rapid opening of the trunk lid under the action of the torsion spring and fast closing, but the hinged structure of the existing hinge movable arm 6 and hinge base 5 is only through friction between the inner surface of the bushing fixedly connected with the hinge movable arm 6 and the ...

Problems solved by technology

For the existing trunk lid opening system, when the trunk lid is opened and closed, the gooseneck-shaped hinge movable arm 6 generates frictional torque on the hinge base 5 to resist the rapid opening of the trunk lid under the action of the torsion spring and fast closing, but the hinged structure of the existing hinge movable arm 6 and hinge base 5 is only through friction between the inner surface of the bushing fixedly connected with the hinge movable arm 6 and the outer surface of the bushing fixedly connected with the hinge shaft To provide friction torque, so it cannot generate enough friction torque, so that the trunk lid is prone to rapid opening and rapid closing under the action of torsion spring, which brings danger
