Both of a requirement for absorption of an impact load in a collision and a requirement for layout of direction and position of a steering wheel are satisfied based on a vehicle-body front structure that includes a partition wall portion which demarcates a vehicle cabin inside space. A lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position. A traveling motor is installed below the lower-side portion of the partition wall portion. A recess portion which is recessed toward vehicle front is formed in a portion, on an upper side of the traveling motor, in the partition wall portion. An inserting hole through which a steering shaft is inserted is formed in a lower wall portion of the recess portion.

In an engine compartment, an engine, a generator using the engine as a power source, a motor for driving the vehicle, and a gear box are arranged in alignment in a vehicle width direction. The first high-voltage equipment is vertically provided on a generating unit that includes the engine and the generator. The second high-voltage equipment is vertically provided on a drive unit that includes the motor and the gear box. The first high-voltage equipment and the second high-voltage equipment are coupled by a coupling member that extends substantially horizontally in the vehicle width direction and supports the high-voltage equipment, against a falling load directed from one thereof toward the other.

In-vehicle structure of electrical equipment

A front vehicle-body structure of a vehicle includes: side frames of a suspension subframe; a cross member connecting front-end portions of the side frames in the vehicle width direction; a front beam member; and a connecting member connecting a front-end portion of each side frame to the front beam member. A high-rigidity portion having a higher rigidity than other portions of the side frame is at a connecting portion between the front-end portion of the side frame and the cross member. The front beam member has a side end portion extending on a vehicle-width-direction outer side relative to a connecting position with the connecting member. A protrusion portion protruding from the side end portion toward a vehicle rear side is to come into contact with the high-rigidity portion from the vehicle-width-direction outer side when a collision load from a vehicle front side is input to the side end portion.

In a vehicle having a large side door opening, a vehicle-body structure suppresses, during a collision in which an apron reinforcement recedes, bending deformation of a hinge pillar at a mounting portion of the apron reinforcement. Embodiments include a reinforcement member inside a closed cross-section of a hinge pillar overlapping a mounting portion of an apron reinforcement in the up-down direction. The reinforcement member includes a body extending in the up-down direction spaced apart from the hinge pillar, a front flange portion at a front portion of the body, a lateral flange portion at a rear portion of the body, a front ridge portion between the body and the front flange portion, and a rear ridge portion between the body and the lateral flange portion. Each of the front ridge portion and the rear ridge portion is continuously provided over the reinforcement member in the vehicle up-down direction.

Vehicle-body structure of vehicle

A front vehicle-body structure includes a front wheel including a wheel; and a side sill that extends in a front-rear direction on a rear side of the front wheel and has side sill inner and outer portions positioned on vehicle-width-direction inner and outer sides, respectively. Vehicle-width-direction end portions of the inner and outer portions are joined at a joined portion formed by the vehicle-width-direction end portions abutting against each other. The inner portion has a higher buckling strength in the front-rear direction than the outer portion. The joined portion has a second joined portion extending inclined to the vehicle-width-direction outer side toward a rear side, and a first joined portion bent from the second joined portion, extending to a front side, and positioned on a front-end portion of the side sill closer to the vehicle-width-direction inner side than a center line of the wheel in the vehicle width direction.

To provide a vehicle-body structure of a vehicle which can achieve both absorption of a front-end collision load acting on a side sill via a front wheel and prevention of receding of the front wheel toward the vehicle-width-direction inner side. The vehicle-body structure of the vehicleincludes front wheelsand side sillsin which a side sill outerand a side sill innerform a closed cross-section; the side sill innerincludes an inner bodyin an open cross-sectional shape open on the vehicle-width-direction outer side, and an inner front endconnected to a front end of the inner body; the side sill outerincludes an outer bodyin an open cross-sectional shape open on the vehicle-width-direction inner side, and an outer front endconnected to a front end of the outer body; and the inner body, the outer body, the inner front end, and the outer front endare configured in such a manner that deformation strength against a pressure load from the vehicle front side decreases stepwise in this order.

The crush canis provided therein with the ribsand. The front side framehas the inner plate partand the outer plate partin the vehicle width direction. The inner plate partand the outer plate partare provided with recessed linear portionsandrecessed toward an inner side of the front side frameand extending in the vehicle front and rear direction, respectively. The recessed linear portionsandand the ribsandof the crush canare disposed at approximately the same heights, respectively.

The crush canis provided therein with the ribsandextending in the vehicle front and rear direction. The bumper beamis provided therein with the ribsandextending in the vehicle front and rear direction. The ribof the crush canand the ribof the bumper beamare disposed at approximately the same height, and the ribof the crush canand the ribof the bumper beamare disposed at approximately the same height.

The inner side of the crush canin the vehicle width direction extends forward relative to the outer side. The inner side of the crush canin the vehicle width direction is formed with the cutout portionstoby cutting off a part of a material.

When viewed from the vehicle front and rear direction, the front end portions of the upper plate part, the lower plate part, the left plate part, and the right plate partof the left front side frameand the rear end portions of the upper wall part, the lower wall part, the left wall part, and the right wall partof the left crush canoverlap each other.

A reinforcing member is provided inside a closed cross section of a front side frame at a position, in a vehicle longitudinal direction, which corresponds to a forming position of a bead. The reinforcing member extends between an outward side wall portion and an inward side wall portion of the front side frame. The reinforcing member is joined to the outward side wall portion and the inward side wall portion of the front side frame. A joint length, in the vehicle longitudinal direction, of the reinforcing member and the inward side wall portion is set to be longer than that of the reinforcing member and the outward side wall portion.

Vehicle-body structure

A first projection portion projecting outward, in a vehicle width direction, from a front side frame is provided. A front end of the first projection portion is located at the same position, in the vehicle longitudinal direction, as a connection portion of a crash can to the front side frame or located in back of the connection portion. An outward side face of the first projection portion is configured to slant rearward and inward in a plan view. The first projection portion and a power unit are arranged to overlap each other in the vehicle longitudinal direction. Accordingly, an impact transmitted to a vehicle-compartment side in a small overlap collision can be reduced, restraining repair costs of the crash can broken in a low-speed collision as well as maintaining appropriate design flexibility of a vehicle-body front portion.
