Problems solved by technology

[0002] like image 3 As shown, the existing car engine cover hinge has a small deformation space and a large vertical stiffness because the hard point is located in the engine cover. When the car collides with the pedestrian's head, the existing hinge structure is not easy to deform and collapse, and the pedestrian's head protection effect Poor, difficult to meet the requirements of pedestrian protection

Embodiment Construction

[0021] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0022] Such as figure 1 and figure 2 As shown, the automobile engine cover crush hinge structure includes a movable leaf 1 and a fixed leaf, wherein the fixed leaf includes a fixed leaf body 3 and a transition leaf 2, and the movable leaf 1 is connected to the The transition boards 2 are hinged, one end of the transition board 2 is connected to the fixed board body through a shear pin, and the other end of the transition board 2 is connected to the fixed board body through a fixing pin.

[0023] When a car collides with a pedestrian's head, when the head hits the area above the hinge of the engine cover, it is crushed because it exceeds the fracture limit of the shear pin, so that the movable and fixed panels collapse, reaching a The purpose of fully absorbing energy. The movable leaf boar...

Abstract

The invention discloses a vehicle engine cover bruising hinge structure. The structure comprises a movable hinge plate and a fixed hinge plate; the fixed hinge plate comprises a fixed hinge plate body and a transition hinge plate; the movable hinge plate is hinged with the transition hinge plate through a pin shaft module; and the transition hinge plate is hinged with the fixed hinge plate body through a shearing pin. The vehicle engine cover bruising hinge structure is reasonable in design, and is liable to collapse when a vehicle and a pedestrian head are collided to increase the engine cover deformation space so as to achieve the purpose of improving the protecting effect of the pedestrian head; the movable hinge plate is deformed and collapsed without separating from the fixed hinge plate, and the energy is fully absorbed to achieve reliability and safety; and the structure is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of an automobile engine cover, in particular to a crush-type hinge structure of an automobile engine cover. Background technique [0002] Such as image 3 As shown, the existing car engine cover hinge has a small deformation space and a large vertical stiffness because the hard point is located in the engine cover. When the car collides with the pedestrian's head, the existing hinge structure is not easy to deform and collapse, and the pedestrian's head protection effect Poor, difficult to meet the requirements of pedestrian protection. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a crush-type hinge structure for an automobile engine cover, so as to increase the deformation space of the engine cover and improve the protection effect of pedestrians' heads. [0004] In order to solve the problems of ...
