Abstract

A vehicle front structure includes a connecting member ( 10 ) formed of a belt-shaped metal plate, the connecting member ( 10 ) has a plate-shaped bottom section ( 11 ), a first folded section ( 12 ) formed by folding a circumferential edge of the bottom section ( 11 ) and a circumferential wall section ( 13 ) that is formed in a continuous annular shape and that continues to the bottom section ( 11 ) via a folded section ( 12 ), and the bottom section ( 11 ) of the connecting member is formed in a V shape upward or downward in a longitudinal direction.

First claim

What is claimed is:

1. A vehicle front structure comprising:
a connecting member formed of a belt-shaped metal plate configured to couple a power unit and a vehicle body,
wherein the connecting member has a first fastening section provided at one end portion of the connecting member in a longitudinal direction and a second fastening section provided at other end portion of the connecting member in the longitudinal direction, the first fastening section being fastened to a connecting bracket fixed to a damper housing of the vehicle body and the second fastening section being fastened to a mount section of the power unit,
wherein the connecting member includes a plate-shaped bottom section, a first folded section formed by folding a circumferential edge of the bottom section and a circumferential wall section that is formed in a continuous annular shape and that continues to the bottom section via the first folded section,
wherein the bottom section of the connecting member is formed between the first fastening section and the second fastening section in the longitudinal direction and is formed in a V shape protruding upward or downward in the longitudinal direction.

2. The vehicle front structure according to claim 1 ,
wherein a second folded section bent upward or downward is formed at the bottom section, and
wherein a hole forming section is formed in the first folded section of the connecting member at a position that corresponds to a position where the second folded section is formed at the bottom section,
wherein the hole forming section includes a hole which is formed to a size such that the circumferential wall section remains.

3. The vehicle front structure according to claim 1 ,
wherein the connecting member connects the mount section of the power unit and the damper housing of the vehicle body in the longitudinal direction with respect to a front side frame of the vehicle body.

4. The vehicle front structure according to claim 2 ,
wherein the connecting member connects the mount section of the power unit and the damper housing of the vehicle body in the longitudinal direction with respect to a front side frame of the vehicle body.

5. The vehicle front structure according to claim 2 ,
wherein a third folded section bent in a lateral direction is formed in the connecting member at a position different from the second folded section of the bottom section when seen in a plan view, and
wherein a bead shape that does not cross the second folded section is formed at the third folded section.

6. The vehicle front structure according to claim 3 ,
wherein the connecting bracket includes a sidewall section fixed to an inner sidewall of the damper housing of the vehicle body and, a lateral wall section having a fastening seat surface formed by folding a lower end of the sidewall section toward a center in a vehicle body widthwise direction,
wherein a plurality of fixing sections for fixing the side wall section to the inner sidewall of the damper housing of the vehicle body is formed at front and rear sides of the sidewall section,
wherein the plurality of fixing sections respectively include a plurality of coupling sections arranged in upward and downward direction,
wherein the plurality of fixing sections are arranged so that each of central axes of the plurality of fixing sections are defined by alignments of the plurality of coupling sections, respectively, and, among the plurality of fixing sections, the central axis of the fixing section which is positioned closer to the rear sides more inclined rearward than the central axis of the fixing section which is positioned closer to the front side, and
wherein bead shapes in a vertical direction are formed between the plurality of fixing sections.

7. The vehicle front, structure according to claim 3 ,
wherein the connecting bracket includes a clearance-shaped section with respect to a cable of an electronic part and an attachment seat surface configured to attach a band clip of the cable.

8. The vehicle front structure according to claim 7 ,
wherein the second, fastening section of the connecting member is arranged at the substantially same vertical height as the first fastening section.

9. The vehicle front structure according to claim 8 ,
wherein the mount section of the power unit includes a front fastening section and a rear fastening section fixed to the front side frame at front and rear sides of the folded section of the forward side of the front side frame.

10. The vehicle front structure according to claim 3 , further comprising the power unit including a fuel cell stack, a motor and a, transmission, the front side frame and a sub-frame fixed to the front side frame,
wherein the power unit is mounted on a sub-frame,
wherein the fuel cell stack is fixed to the mount section and a stack sub-frame fastening section of the sub-frame,
wherein the motor and the transmission are fixed to a trio or/mission sub-frame fastening, section of the sub-frame,
wherein the front side frame is folded and deformed upon collision from a forward side, and
wherein the sub-frame is able to be folded and deformed in a V shape protruding downward upon collision from the forward side to fall from the front side frame.

11. The vehicle front structure according to claim 10 , further comprising a power control unit,
wherein, in the power unit, the fuel cell stack is arranged above the motor and the transmission and,
wherein the power control unit is arranged in front of the power unit.

12. A vehicle front structure comprising:
a connecting member formed of a belt-shaped metal plate configured to couple a power unit and a vehicle body,
wherein the connecting member includes a plate-shaped bottom section, a first folded section formed by folding a circumferential edge of the bottom section and a circumferential wall section that is formed in a continuous annular shape and that continues to the bottom section via the first folded section,
wherein the bottom section of the connecting member is formed in a V shape protruding upward or downward in a longitudinal direction, and
wherein a second folded section bent upward or downward is formed at the bottom section, and
wherein a hole forming section is formed in the first folded section of the connecting member at a position that corresponds to a position where the second folded section is formed at the bottom section,
wherein the hole forming section includes a hole which is formed to a size such that the circumferential wall section remains.
