Abstract

The invention discloses an optimized engine shield plate. The optimized engine shield plate comprises an inner shield plate and an outer shield plate which are welded together, and the inner shield plate is of a bilaterally symmetrical structure. A first triangle, a second triangle, a third triangle, a fourth triangle and a fifth triangle are distributed on the left side of the inner shield plate, each corner of the triangles is in arc transition connection, and vertical edges are welded along edges of the triangles to form reinforcing ribs of the inner shield plate. An irregular arc-shaped hole is arranged on the right side of a symmetric line close to the position of the lower edge of the inner shield plate, and vertical edges are welded on the edges of the hole to form reinforcing ribs. Accordingly, the optimized engine shield plate can bear excitation caused by an engine, a vehicle body and the road surface, and firmness in touch is simultaneously taken into account when the optimized engine shield plate is touched. When bearing loads, the optimized engine shield plate also has static bend resistance and torsion rigidity, low-order frequency of the engine shield plate is effectively kept away from excitation frequency, and harm caused by resonance is avoided.

Description

A kind of optimization bonnet panel

Technical field

The present invention relates to automobile manufacturing field, particularly relate to a kind of optimization bonnet panel.

Background technology

Along with the fast development of auto-industry, its product design more and more receives publicity, and energy resource consumption simultaneously is also outstanding day by day.Guaranteeing or improving under the prerequisite of structural behaviour that reduce architecture quality, have very important significance: lightweight can reduce automobile fuel consumption, reducing structural materials and use, improving structural behaviour etc.; Therefore, the lightweight technical study has very important meaning for developing of automobile industry.

Automotive hood is the important component part of auto body; Its keystone configuration is made up of inner panel and outside plate; Inner panel and outside plate combine through modes such as flange, bonding, roll weldings; Its structural requirement also need satisfy requirements such as mechanical mechanics property requirement, passive satety except attractive in appearance.In the design of existing automotive hood, have certain problem, satisfying under the condition of passive satety, cover plate is more thick and heavy with regard to design-calculated, alleviates to have satisfied not safety and performance requriements such as anti-twist behind the component again.

Summary of the invention

The technical matters that the present invention mainly solves provides a kind of optimization bonnet panel; Can bear the excitation that driving engine, vehicle body, road surface bring; Should have crash-resistant sensation in the time of simultaneously also will considering to touch, when bearing load, also have static counter-bending and torsional rigidity; Effective low order frequency of bonnet panel that must make is avoided excitation frequency, avoids producing the harm that resonance brings.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of optimization bonnet panel is provided, and this optimization bonnet panel comprises the inner cover plate and the outside jacket plates of weld together; Said inner cover plate is the left-right symmetric structure, and the inner cover plate left side is distributed with first triangle, second triangle; The 3rd triangle; The 4th triangle and the 5th triangle, leg-of-mutton each angle adopts arc transition to be connected, and all is welded with the reinforced rib that stile forms inner cover plate along leg-of-mutton limit; The symmetric line right side at place, inner cover plate lower edge is provided with a fitfull circular hole, and the limit in hole all is welded with stile and forms reinforced rib.

Preferably, each angle degree of said first triangle is followed successively by 41 °, 29 °, 110 °.

Preferably, each angle degree of said second triangle is followed successively by 52 °, 73 °, 70 °.

Preferably, each angle degree of said the 3rd triangle is followed successively by 14 °, 45 °, 122 °.

Preferably, each angle degree of said the 4th triangle is followed successively by 58 °, 12 °, 110 °.

Preferably, each angle degree of said the 5th triangle is followed successively by 57 °, 53 °, 70 °.

The invention has the beneficial effects as follows: a kind of optimization bonnet panel of the present invention; Can bear the excitation that driving engine, vehicle body, road surface bring; Should have crash-resistant sensation in the time of simultaneously also will considering to touch, when bearing load, also have static counter-bending and torsional rigidity; Effective low order frequency of bonnet panel that must make is avoided excitation frequency, avoids producing the harm that resonance brings.
