Problems solved by technology

[0007] However, in the vehicle body front structure disclosed by the Japanese Patent Gazette, the impact load transmission path is long (detour), and the number of related members is increased.
The resulting disadvantage is that the front body structure becomes complex and thus increases production costs

Embodiment Construction

[0021] The vehicle body front structure of the vehicle according to the present invention will be described below based on the illustrated embodiment.

[0022] figure 1 is a perspective view of the vehicle body front structure of the embodiment of the present invention. Figure 2A and 2B It is a schematic diagram showing the structure and function of the front part of the vehicle body in the same embodiment of the present invention.

[0023] like figure 1 As shown, front side members 1 each having a closed cross-sectional structure are provided on left and right sides of a vehicle body front in such a manner as to extend in the longitudinal direction of the vehicle. A front floor cross member 3 made of a pipe extends between left and right front pillars 2 serving as vehicle body side walls.

[0024] The side member 1 is bent to be inclined downward from a front position which is a predetermined distance away from a position directly below the front floor cross member 3, ...

Abstract

A vehicle front-end body structure, includes: front side members provided along a left side and a right side of a front portion of a vehicle body, a front deck cross member provided between side walls of the vehicle body, including joint portions for joining the front deck cross member to the side walls; and a connecting member made up of a pipe material including end portions and a middle portion disposed between the end portions. The end portions are joined to the vicinities of the joint portions respectively. The middle portion is joined to the front side members respectively.

Description

technical field [0001] The present invention relates to a vehicle body front structure. Background technique [0002] The recent demand for passenger cars has changed the design structure of passenger cars, and made the floor set more forward or adopt "floor forward design" in order to expand the space of the passenger compartment. As a result, the length of the vehicle front side member tends to be shortened. Therefore, it is difficult to ensure that a vehicle employing a collapsible body has sufficient impact absorbing performance to absorb the impact at the time of a collision. [0003] For example, if image 3 As shown, the front side members 100 are provided at the front ends of the left and right sides of the vehicle body extending in the longitudinal direction of the vehicle. The front side member 100 is bent downward at a position directly below or in front of a front floor cross member 102 extending between left and right front pillars 101 . The front side member...
