Description

TECHNICAL FIELD The present invention relates to a vehicle body structure of an automobile, particularly a cab-over type vehicle.

2. Description of the Related Art FIG. 3 shows a vehicle body structure of a conventional cab-over type vehicle. Reference numeral 1 denotes a vehicle body, and a portion of a floor 2 on which a seat 3 is placed and fixed is bulged toward a passenger compartment. An engine room 4 is formed below it. Reference numeral 5 denotes a pair of left and right side frames, and the power unit 6 is mounted on these side frames in the engine room 4 via an engine mount (not shown). This similar structure is disclosed in, for example, Japanese Patent Laid-Open No. 58-12871.

When the power unit 6 inertially moves forward during a frontal collision of the vehicle, the power unit 6 collides with the front wall 7 of the engine room 4, deforms the front wall 7, and lowers the front part of the seat 3. Narrows the leg space of. Therefore, the present invention provides a vehicle body structure of a cab-over type vehicle that can prevent the power unit from interfering with the front wall of the engine room during inertial movement of the power unit during a frontal collision and can secure a leg space. Is.

Means for Solving the Problems In a structure in which a seat mounting portion of a floor is formed to bulge toward a vehicle compartment and an engine room for mounting a power unit is formed below the seat mounting portion, the upper wall and the lower end of the front wall of the engine room are formed. There is provided a slope member which is spaced apart from the front wall and obliquely extends from the front wall, and which guides the power unit to slide downward when the power unit moves forward.

Action When the power unit inertially moves forward during a frontal collision of the vehicle, the power unit collides with the slope member and is slidably guided downward along the slope of the slope member to avoid collision with the front wall of the engine room. It

Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings by attaching the same reference numerals to the same portions as those of the conventional configuration.

1 and 2, the floor 2 of the vehicle body 1 has a portion on which the seat 3 is placed and fixed, which is bulged toward the passenger compartment side, and an engine compartment 4 is formed below the portion. The power unit 6 is mounted in the engine room 4 between the left and right side frames 5 via an engine mount (not shown).

Here, in the engine room 4, a slope member 9 is formed near the front upper edge of the power unit 6 and obliquely extends between the upper wall 8 and the lower end of the front wall 1 apart from the front wall 7. Are connected and arranged. In the present embodiment, a pair of left and right beam members is used as the slope member 9. One bracket 10a of the beam member 10 is fixed to the lower surface of the upper wall 8 with bolts and nuts 11, and the other bracket 10a is attached to the front wall of the floor 2. 7 Bolts and nuts 11 are fixedly provided on the lower surface of the forming base.

According to the above-described structure of the embodiment, when the power unit 6 inertially moves forward during a frontal collision of the vehicle, the front upper edge of the power unit 6 collides with the pair of beam members 10 and follows the inclination of the beam members 10. It is forcibly slid downwardly and guided, and in some cases is forced to fall downward to avoid collision with the front wall 7 of the engine room 4. As a result, the deformation of the front wall 7 protruding into the passenger compartment is prevented, and the leg space in front of the seat 3 can be secured.

As described above, according to the present invention, even if the power unit mounted in the engine room moves inertially forward when a frontal collision of the vehicle occurs, the power unit is forced by the slope member along the slope of the slope member. Since it is slidably guided diagonally downward to avoid collision with the front wall of the engine room, it is possible to prevent the front wall of the engine room from protruding and deforming into the vehicle interior, and to secure a leg space in front of the seat, which is safe. It has a great practical effect that it can be further enhanced.
