Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as Figure 1~5 As shown, the present invention provides an automatic pull-cord type four-bar linkage hinge mechanism for opening and closing the hood, including a four-bar linkage mechanism 1 and a drawstring mechanism 2 matched with the four-bar linkage mechanism, and the four-bar linkage mechanisms are mutually independent. Two adjacent connecting rods are respectively connected with the car body and the machine cover 3, and the pull rope mechanism realizes the opening and closing of the machine cover by driving the four-bar linkage hinge mechanism. The drawstring mechanism includes a drawstring 2-1 and a motor 2-2. One end of the stay cord is connected to the four-bar linkage mechanism, and the other end is connected to the motor. The motor controls the opening and closing of the four-bar linkage mechanism through the stay rope, thereby realizing the opening ...

Abstract

The invention discloses an automatic pull rope type four-connecting-rod hinge mechanism for opening and closing a hood. The mechanism comprises a four-connecting-rod mechanism, two non-adjacent connecting rods of the four-connecting-rod mechanism are respectively connected with a vehicle body and the hood, and the automatic pull rope type four-connecting-rod hinge mechanism is characterized by comprising a pull rope mechanism matched with the four-connecting-rod mechanism, and the pull rope mechanism comprises a pull rope and a motor; and one end of the pull rope is connected with the four-connecting-rod mechanism, the other end of the pull rope is connected with the motor, and the motor controls opening and closing of the four-connecting-rod mechanism through the pull rope, so that opening and closing of the hood are achieved. The pull rope and the motor are adopted as a power assisting device for opening the hood, and the pull rope and the motor apply pulling force to one connecting rod of the four-connecting-rod mechanism, so that control over opening and closing of the hood is achieved. Moreover, the length and the direction of the pull rope can be randomly adjusted, so that the arrangement position of the motor is not limited, a large arrangement space is saved, and the design difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile hood control, in particular to an automatic pull-cord type four-link hinge mechanism for opening and closing the hood. Background technique [0002] At present, the hood (or tailgate) and the vehicle body are connected by hinges, and the hood (or tailgate) is mainly opened and assisted by pneumatic struts and electric struts. Pneumatic struts and electric struts are bulky and need to be arranged near the hinge mechanism, which takes up a lot of space inside the hood (or tailgate), so that the arrangement of pneumatic struts and electric struts is limited. Contents of the invention [0003] The present invention provides an automatic pull-cord type four-link hinge mechanism for opening and closing the hood with flexible arrangement in view of the shortcomings of the above-mentioned prior art. [0004] The technical scheme adopted in the present invention is: an automatic drawstring type four-...
