Automobile luggage case link connection apparatus

Abstract

The invention discloses a vehicle boot hinge joint device, wherein one end of a first side link is articulated with a frame through a first hinge point, while the other end is articulated with the rod body of a connecting rod through a fourth hinge point; one end of a second side link is articulated with the frame through a second hinge point, while the other end is articulated with the end part of the connecting rod through a third hinge point; the distance between the first hinge point and the second hinge point is between 125.38 and 141.42mm; the distance between the first hinge point and the fourth hinge point is between 229.46 and 242.03mm; and the distance between the third hinge point and the fourth hinge point is between 35 and 38mm. Moreover, when a four-rod hinge mechanism is completely opened, the maximum opening angle a formed by the connecting line of the first hinge point and the second hinge point as well as the connecting line of the second hinge point and the third hinge point is between 102 and 108 degrees. The vehicle boot hinge joint device has the characteristics of reasonable design and easy implementation, etc.; moreover, the device can effectively prevent rain water from flowing into a boot when a boot cover is opened, thereby preventing articles inside the boot from getting wet by rain.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a hinge connection device for a trunk of an automobile. Background technique [0002] The trunk lid of the car is installed at the rear of the car body through a four-bar hinge mechanism. When the four-bar hinge mechanism is opened, the trunk lid is in an open state; when the four-bar hinge mechanism is closed, the trunk lid is in a closed state. The general four-bar hinge mechanism is composed of a frame, a connecting rod, a first connecting rod and a second connecting rod, wherein one end of the first connecting rod is hinged with the frame through the first hinge point, and the other end is hinged through the fourth hinge. One end of the second connecting rod is hinged to the frame through the second hinge point, and the other end is hinged to the end of the connecting rod through the third hinge point. The distance between the first hinge point and the second...

AI Technical Summary

Problems solved by technology

Due to design defects, the distance between the hinge points of the four-bar hinge mechanism is unreasonable, so that when the four-bar hinge mechanism is fully opened, the connection line between the first hinge point and the second hinge point is connected to the second hinge point and the third hinge point. The maximum opening angle formed by the connecting lines of the hinge points is only 89 degrees. When the trunk lid is fully opened, the projection line of its front edge in the vertical direction is located inside the water-retaining rubber strip on the edge of the trunk, so that rainwater will flow along the trunk lid. Flows into the trunk and wets the contents of the trunk
