Problems solved by technology

[0007] However, in the above-mentioned prior art, since a closed section is formed between the dash panel beam and the lower dash panel, there is a possibility that the dash panel beam protrudes into the interior space of the vehicle compartment, thereby reducing the space utilization ratio of the interior space of the vehicle compartment. The problem

Embodiment approach 1

[0021] figure 1 It is a front view showing a state of a dash panel to which the vehicle body front structure according to Embodiment 1 of the present invention is applied, as seen from the vehicle front side.

[0022] The front structure of the vehicle body includes a dash panel 10 , a windshield cowl 20 , a lower dash panel beam 30 , a left reinforcing panel 41 , a right reinforcing panel 42 , and an L-shaped reinforcing member 50 . Additionally, in the figure 1 In the drawings and others, arrow X indicates the vehicle width direction, arrow Y indicates the vehicle front-rear direction, and arrow Z indicates the vehicle up-down direction.

[0023] The dashboard 10 is to divide the engine room ER and the vehicle room RM (refer to figure 2 ) is formed by joining the upper end of the lower dash panel 11 and the lower end of the upper dash panel 12 .

[0024] Such as figure 2 As shown, the joining is carried out by bending the lower end portion of the lower dash panel 11 to...

Abstract

The present invention provides a vehicle body front structure which enables the space utilization rate not to be reduced and a front surrounding plate to be enhanced. The vehicle body front structure comprises the front surrounding plate (10), and a left reinforcing plate (41) and a right reinforcing plate (42) used for improving the surface rigidity of the lower front surrounding plate (11) are jointed at the left and right separated positions respectively of the lower front surrounding plate (11); an L-shaped reinforcing member (50) of which the cross-section is L-shaped in the vehicle upper and lower directions is jointed on the lower front surrounding plate in a manner of a across spanning a corner part formed by a lower jointing flange part (11f) and a general part (11c) extending along the vehicle upper and lower directions, and the L-shaped reinforcing member (50) is configured to extend along the vehicle width direction and overlap with the left and right reinforcing plates (41,42) in the vehicle front and back directions.

Description

technical field [0001] The present invention relates to a vehicle body front structure that reinforces the rigidity of a dash panel in the vehicle front-rear direction. Background technique [0002] Conventionally, the structure of the dash panel installed at the front of the vehicle body is generally as follows: the dash panel is formed by joining the upper dash panel and the lower dash panel up and down by welding, and a supporting windshield is joined to the upper dash panel. The windshield cowl (cowl top cover). [0003] In such a vehicle body front structure, there is known a structure that reinforces the rigidity of the dash panel in the vehicle front-rear direction (for example, refer to Patent Document 1). [0004] In this patent document 1, it is disclosed that a dash cross member (Japanese: ダッシュクロスメンバ) extending in the vehicle width direction forms a closed section between the dash cross member and the upper rear surface side of the lower dash panel. The structur...
