Problems solved by technology

In order to sufficiently absorb the collision energy, the left and right mounting brackets for connecting the subframe need to be large, and the weight of the vehicle body will increase.
Furthermore, the vehicle body front structure known in the above-mentioned Patent Document 5 is a structure that can be applied only when the left and right mounting brackets for connecting the subframe are provided.

Embodiment

[0052] The vehicle body front structure of the embodiment will be described. like figure 1 and figure 2 As shown, vehicle 10 is, for example, a passenger car. A power unit compartment 12 at the front and a vehicle compartment 13 located directly behind the power unit compartment 12 are formed inside a vehicle body 11 of the vehicle 10 .

[0053] A power unit 20 is housed in the power unit chamber 12 . The power unit 20 is a so-called transverse type power unit in which an engine 21 and a transmission 22 are arranged in the vehicle width direction and combined with each other.

[0054] like Figure 1 to Figure 4 As shown, the vehicle body 11 is constituted by a monocoque body, and is formed in a left-right symmetrical shape with respect to a vehicle width centerline CL passing through the center of the vehicle 10 in the vehicle width direction and extending in the vehicle front-rear direction. The front portion of the vehicle body 11 includes a dashboard lower panel 30 , ...

Abstract

A vehicle body front structure includes left and right front side frames including at least left and right front bending portions, left and right middle bending portions, and left and right rear bending portions. The left and right front bending portions are bent to project inwards in a vehicle's width direction by a collision load exerted on a front end of a vehicle body, whereby the left and right front bending portions restrain a power unit. The left and right middle bending portions are situated spaced apart to the rear from the left and right front bending portions. The left and right rear bending portions are situated spaced apart to the rear from the left and right middle bending portions, are bent outwards in the vehicle's width direction, and absorb collision energy when struck by the power unit moved rearward together with the left and right front bending portions.

Description

technical field [0001] The present invention relates to a vehicle body front structure in which left and right front side frames capable of mounting a power unit are improved. Background technique [0002] Common vehicles such as automobiles have left and right front side frames at the front of the vehicle body. The left and right front side frames extend from the lower panel of the dashboard toward the front of the vehicle body, and can mount a power unit such as an engine unit. [0003] The left and right front side frames can be plastically deformed by a collision load (frontal collision load) acting on the front end of the vehicle body from the front. At this time, the power unit moves toward the rear of the vehicle body and touches the lower panel of the instrument panel. In contrast, it is desired to improve the performance of protecting occupants located in the vehicle interior behind the dashboard lower panel. In order to improve the protection performance for the...
