Definitions
- the present invention relates to a vehicle body structure, and more particularly to a vehicle body reinforcement structure for securing a living space in a frontal collision.
- Patent Document 1 discloses a structure for receiving a load by inserting a reinforcing member called an impact beam in the front-rear direction in a door in order to secure a living space at the time of a frontal collision in a carry-over type vehicle. ing.
- Patent Document 1 JP-A-10-138757
- the present invention pays attention to such a background, and proposes a vehicle body reinforcement structure capable of exhibiting the same or better living space securing performance without using the door interior type reinforcement member as described above.
- the vehicle body reinforcement structure according to the present invention is configured so that at least one rod-like body is arranged substantially in the front-rear direction of the vehicle body along the lower surface of the floor panel constituting the cap and at least the force near the front end of the floor panel to the seat installation site. It is characterized by extending in the direction.
- This rod-like body can be provided over the entire length of the floor panel near the front end and near the rear end, but preferably it terminates at the seat installation site, and the rear part of the rear part of the force is applied only to the floor panel. Therefore, it is relatively easy to deform! It is preferable that a deformed portion is formed. By forming the deformed part in the rear part of the cap behind the seat in this way, it can function like a crushable zone that absorbs impact during a collision. It becomes possible.
- the two rod-like bodies may be extended from the vicinity of the front end of the floor panel to the seat installation site while being separated from each other.
- the rod-like body is extended along the lower surface of the floor panel, there is a problem of limitations that exist when it is provided on a door that is a movable part and has internal parts. The point can be solved.
- the space between the vicinity of the front end of the floor panel corresponding to the underside of the seated occupant and the seat installation site is at least reinforced, it is possible to obtain a structure that relatively securely protects the passenger from deformation of the cab, which is a characteristic of a cab-over vehicle. I can do it.
- the rod-shaped body is terminated at the seat installation site, and the rear part of the rear of the cap functions as a crashable zone, so that the rod-shaped body absorbs an impact while absorbing the impact in the crashable zone. Since the structure can be obtained, the probability that a living space can be secured can be increased.
- FIG. 1 is a schematic cross-sectional view showing a cap portion of a cap-over type vehicle provided with a vehicle body reinforcing structure according to the present invention.
- FIG. 2 is a view showing the embodiment of FIG.
- FIG. 1 and FIG. 2 show a specific example when the present invention is applied to a carry-over type vehicle.
- a total of three rods 1 and 2 on the driver's seat side and one rod 3 on the passenger's seat side are attached to the bottom surface of the floor panel 4 so that they are near the front edge of the floor panel 4. In addition, it extends in the longitudinal direction (arrow X) between the seat S (driver's seat and passenger seat).
- the rod-like bodies 1, 2, and 3 can use steel materials such as prismatic columns, cylinders, and pipes. In consideration of weight and cost, pipe-shaped ones are used in this example.
- the front end portion 5 of the floor panel 4 is pivotally supported by the vehicle body frame F so as to be rotatable by a front cap mount.
- the rod-like bodies 1, 2, and 3 extend from the vicinity of the front end 5 of the floor panel 4 to the seat S installation site, and terminate at the seat S installation site. Therefore, the area between this end point and the rear end 6 of the floor panel 4 with the rear cab mount is a deformable part that is relatively easier to deform than the front part with the rod-like bodies 1, 2, and 3. It functions as a crushable zone Z.
- this crushable zone Z By setting this crushable zone Z, the rod-like bodies 1, 2, and 3 receive the load in the axial direction at the time of frontal collision, while the crushable zone Z collapses and absorbs the impact. A certain survival space can be secured!
- Each rod-like body 1, 2, 3 is formed so as to follow the shape of the lower surface of the floor panel 4, and is bolted using a bracket.
- the fixing method is not limited to this, and welding may be used.
- each of the rod-like bodies 1, 2, and 3 is provided with a bracket B fixing portion at the middle portion in addition to the front and rear end portions thereof.
- the bottom surface of the floor panel 4 is reinforced with rod-like bodies 1, 2, and 3 to enhance impact resistance, and a crushable zone Z is provided behind this to design shock absorption. Can contribute to the improvement of the living space securing performance of the seated occupant To do.
- the two rod-like bodies 1, 2 on the driver's seat side are spaced apart from each other, and the lower side of the passenger seated in the seat S is placed between the two rod-like bodies 1, 2 It can be reinforced with defined surfaces. This makes it possible to further improve the living space securing performance against frontal collisions. If there is no problem in cost, the passenger seat may have a structure in which two rod-like bodies are arranged in the same manner.
