Problems solved by technology

Traditional gas springs used in the trunk lid of a car usually take up a lot of space and cost a lot
Also, gas springs behave differently at different outside temperatures, for example, may provide insufficient lift at low temperatures
Traditionally, the torsion bar spring used in the trunk lid of the car is usually installed across the left and right directions of the trunk lid. The structure is complex, difficult to assemble, and it also needs to occupy a large space

Abstract

A trunk lid opening device includes a hinge seat configured to be mounted to an automobile body; a hinge arm pivotally hinged to the hinge seat between a retraction position and a raising position andconfigured to be mounted to an automobile trunk lid; a slider attached to the hinge arm and slidable relative to a part of the hinge arm; and a spring provided with a common lower end and a pair of branched upper ends, wherein the lower end is rotatably connected to the slider, and the pair of branched upper ends are separately rotatably mounted to the hinge seat at different spring mounting positions so that the spring can elastically deform between the slider and the hinge seat to generate a force acting on the hinge arm through the slider.

Description

technical field [0001] The present application relates to a device for opening the trunk lid of an automobile, which utilizes a spring-slider combination mechanism to assist the opening of the trunk lid of the automobile. Background technique [0002] Automobile trunk lids are usually equipped with gas springs or torsion bar springs to provide lifting force to them when opening the trunk lid, so as to assist the automatic opening of the trunk lid. The gas springs traditionally used in the trunk lid of automobiles usually take up a lot of space and are expensive. Furthermore, gas springs behave differently when the outside temperature is different, for example, the lifting force provided may not be sufficient at low temperatures. Traditionally, the torsion bar springs used in the trunk lid of automobiles are usually installed across the left and right directions of the trunk lid. The structure is complex, difficult to assemble, and it also needs to occupy a large space. [...
