Automotive engine hood lock mounting plate

Abstract

The invention provides an automotive engine hood lock mounting plate which can reduce the harm to legs of pedestrians during collision. The automotive engine hood lock mounting plate is characterized in that: a section of the mounting plate is in a Z shape; the mounting plate comprises a lower mounting face, a side face and an upper mounting face; the lower mounting face and the side face are provided with mounting holes used for mounting an engine hood lock. During use, the upper mounting face of the mounting plate is connected with an upper beam of a water tank, and the engine hood lock is fixed with the side face and the lower mounting face of the mounting plate through bolts. When the engine hood lock is collided with the legs of the pedestrians, the force is transferred to the mounting plate, the mounting plate takes a lapping joint between the mounting plate and the upper beam of the water tank as an axis to rotate, the collision energy is absorbed, simultaneously the collision time is prolonged, the impact on the legs of the pedestrians is reduced, and the safety of the pedestrians is protected. When a vehicle is collided with other obstacles at a low speed, the mounting plate bears the impact force from a parallel direction. The mounting plate has the same deformation mode as common mounting plates, and can avoid the ineffectiveness of the engine hood lock during collision.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile hood lock mounting plate. Background technique [0002] In order to meet the use requirements of the hood lock, the rigidity of the hood lock is relatively large, it is difficult to deform it in a collision, and the hood lock is just at the height of the pedestrian's leg, so in the traffic accident between pedestrians and vehicles, The injury to the pedestrian's leg is very serious. Specifically, the hood lock mounting plate is usually fixed on the upper beam of the water tank, and the hood lock is connected to the mounting plate through bolts. During the collision, the bolts mainly bear the shear force, and the impact force is difficult to exceed its shear stress limit. Ineffective, so it is difficult to buffer the external force. How to reduce the injury degree of the hood lock to the legs of pedestrians is an urgent problem to be so...
