Abstract

The invention provides an engine hood hinge structure and a pedestrian protective device. The engine hood hinge structure includes an engine hood, an upper hinge, a lower hinge, a base, a pre-tensioning mechanism for providing a pre-tensioning force for keeping transient fixing connection between the upper hinge and the lower hinge, and an actuation mechanism for pushing the lower hinge to lift upward and breaking the pre-tensioning force; the upper hinge is fixed on the lower surface of the engine hood; a slide groove is formed in the upper hinge; the upper end of the lower hinge is slidingly arranged in the slide groove, and the lower end of the lower hinge is rotatably connected to the base; and the base and the actuation mechanism are fixed on a vehicle body. Compared with the conventional structures in which a hinge shaft is fixedly connected to an engine hood and is pushed by other connection rods, the engine hood hinge structure is simple and flexible, and is simpler in later maintenance.

Description

technical field [0001] The invention relates to the technical field of engine hoods, in particular to an engine hood hinge structure and a pedestrian protection device. Background technique [0002] The patent application with application number CN201410470393 discloses a hood lifting device for pedestrian protection, which includes an upper top cover, a sleeve, a piston, a lower bottom cover, a gas generator, a rubber sleeve, a sealing ring and a rubber sealing sleeve. [0003] The upper top cover is in contact with the engine inner cover through a rubber sleeve, and the bottom of the lower bottom cover is fixed on the car body. When a pedestrian collision danger is detected, the gas generator is triggered, the piston mechanism is pushed, and the upper top cover is lifted, thereby pushing the engine cover to realize It lifts instantly, and after reaching the highest point, the piston mechanism falls back, and the gas struts installed on both sides work to maintain the heigh...
