Embodiment Construction

[0026] Below with reference to the accompanying drawings, through the description of the implementation examples, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part, etc., will be further described. detailed instructions.

[0027] Such as image 3 , 4 , 5, 6, and 7, the front windshield area of ​​the engine cover outer panel 1 of the present invention, namely image 3 At C, there is a step transition 11, and the Y-direction cross-section of the step transition 11 is in turn a step surface transition 111 and a step arc surface transition 112. The middle area is connected, and the bottom of the step arc surface transition 112 is connected to the process supplementary surface 113. The width of the step surface facing the transition 111 is set to W, and the height of the step transition 11 is H, then W≤H / 2, such as Figure 4 shown.

Abstract

The invention provides an engine hood outer plate for improving the rigidity of engine hood outer plate parts. A front windshield area of the engine hood outer plate is provided with a step transition, Y-directional section of the step transition includes a step straight face transition and a step arc face transition sequentially from inside to outside, the front of the step straight face transition is connected to a middle area of the engine hood outer plate, the bottom of the step arc face transition is connected to a process supplementary face, the width of the step straight face transition is set to W, and the height of the step transition is set to H, with W< / =H / 2. The step transition is added to the front windshield area of the engine hood outer plate and includes the step straight face transition and the step arc face transition, parameters of the step transition are constrained, the technical effect of drawing of the engine hood outer plate is optimized, the problem of deformation collapse of the front windshield area of the engine hood outer plate can be solved, and the rigidity of the whole engine hood outer plate is improved.

Description

technical field [0001] The invention relates to the technical field of automobile body-in-white parts design, in particular to an engine cover outer panel which can improve the rigidity of the engine cover outer panel parts. Background technique [0002] With the continuous progress of the automobile industry, people's requirements for the appearance quality and functions of automobiles are also increasing. In the development of complete vehicle projects, designers can control costs by improving material utilization and reducing the number of mold processes, so as to further adapt to the increasingly intensified market competition. In the field of automobile body-in-white, the outer panel of the hair cover is an important surface sheet metal part in the body-in-white parts. It has the characteristics of large structural size and high quality requirements for the outer surface. In order to achieve good external surface quality, the structure of the front windshield area of ​...
