Description

  The present invention relates to a vehicle in which a main skeleton is configured by a structure in which an outer member and an inner member are joined, and a reinforced resin is used for a part of a panel forming the skeleton of the vehicle.

In a vehicle in which a main skeleton is formed by a structure in which such an outer member and an inner member are joined, it is sufficient to ensure the safety of the passenger compartment space from an instantaneous impact or offset collision from the front or side. Strength is required.

  On the other hand, if the strength is improved, the continuity of load transmission with respect to the input of the vehicle body, such as at the time of a curve, is impaired, which affects the steering stability. For this reason, it is required to satisfy both collision safety and steering stability.

  For example, Patent Document 1 discloses a lower structure of a side surface of a vehicle body that reliably disperses and transmits a collision load from the side and front of the vehicle body to other members and suppresses deformation due to the collision.

  Patent Document 2 discloses a structure in which a rail reinforcing portion is provided on a side roof of a vehicle body side and a sill strength adjusting portion is provided on a side sill in order to adjust a vehicle body deformation mode at the time of a side collision.

  On the other hand, Patent Document 3 discloses a technique in which at least one of an inner panel and an outer panel is formed of a fiber reinforced resin in a vehicle body fixing structure of a wire harness.

  1 to 3 show an embodiment of the present invention. A basic embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a vehicle 1 according to an embodiment of the present invention. The vehicle 1 includes a plurality of members and a skeleton, and includes a front pillar portion 10, a roof pillar portion 11, a center pillar portion 12, a side sill portion 13, and the like.

  The front pillar portion 10 forms a front portion that constitutes the cabin space of the vehicle 1 and is arranged so as to hold the side of the windshield. The front pillar portion 10 is formed toward the lower portion of the vehicle and is coupled to the side sill portion 13.

  The roof pillar portion 11 extends in the front-rear direction of the upper part constituting the passenger compartment space of the vehicle 1, and forms a side portion of the roof of the vehicle 1.

  The center pillar portion 12 is a columnar pillar provided between the front door and the rear door of the vehicle 1, and is arranged in the vertical direction between the roof pillar portion 11 and the side sill portion 13 on the side portion of the vehicle 1. .

  The side sill portion 13 is disposed in the lower side of the vehicle 1 in the front-rear direction of the vehicle 1.

  Each member further includes a plurality of members. For example, there are members in which an inner member and an outer member are coupled, and members in which a reinforcement is inserted between the inner member and the outer member. In this embodiment, this inner member is formed of carbon fiber reinforced resin.

  FIG. 2 is an LL sectional view of the vehicle according to the embodiment of the present invention. FIG. 2 is an LL sectional view of the vehicle 1 in FIG. 1. The pillar center inner 21 and the panel side outer 22 are combined. The pillar center inner 21 is made of carbon fiber reinforced resin.

  The pillar center inner 21 and the panel side outer 22 are joined at the end by being hardened with an adhesive, a screw, a rivet, or a resin.

  FIG. 3 is a partially enlarged exploded view of the vehicle according to the embodiment of the present invention. The front pillar portion 10 includes a front pillar outer portion 10A, a front pillar inner portion 10I, and a front pillar inner front portion 10IF. Among these, the front pillar inner part 10I and the front pillar inner front part 10IF are formed of carbon fiber reinforced resin.

  The roof pillar part 11 includes a part of the roof pillar outer part 11A, a part of the center pillar outer part 12A, and a roof pillar inner part 11I. Among these, the roof pillar inner part 11I is formed of carbon fiber reinforced resin.

  The center pillar portion 12 includes a center pillar outer portion 12A and a center pillar inner portion 12I. Of these, the center pillar inner portion 12I is formed of a carbon fiber reinforced resin.

  The side sill portion 13 includes a side sill outer portion 13A and a side sill inner portion 13I. Of these, the side sill inner portion 13I is formed of a carbon fiber reinforced resin.

  Since it comprised as mentioned above, it becomes possible to keep suitably the intensity | strength with respect to a collision with the inner member of each part formed with carbon fiber reinforced resin. In addition, due to the rigidity specific to the carbon fiber reinforced resin, it is possible to suitably transmit the load.

  For this reason, it is possible to achieve both collision safety and steering stability. Moreover, since the inner member which has conventionally used a steel plate, an iron plate, aluminum, etc. was formed with the lightweight carbon fiber reinforced resin, it becomes possible to achieve weight reduction of the vehicle 1 as a whole.

  In addition, for example, when there is an instantaneous force from the front with respect to the front pillar portion 10, if the strength against bending of the front pillar portion 10 and the rigidity to perform transmission are not compatible, the front pillar portion 10 is applied. The force may not be transmitted well and may be bent due to insufficient strength. However, according to the present embodiment, by designing the reinforced resin so as to achieve both strength and rigidity, it is possible to successfully transmit the force applied to the front pillar and prevent bending.

  In addition, the force transmitted from the front side members, one on each of the inner side of the bumper and left and right front wheels, against the force from the front, transmits the stiffener that connects the front pillar portion 10 and the front side member. It is distributed to the part 10, the side sill part 13, the center tunnel and the like. Thereby, the force from the front can be escaped not to the front part of the vehicle but to the rear.

  A member that requires strength to resist external force transmission and external force, such as the front pillar portion 10, the roof pillar portion 11, the center pillar portion 12, and the side sill portion described in FIG. The present invention can be applied not only to the front side member 13 but also to the stiffener and the center tunnel.

  In addition, when there is a gap in the joint part or joint part of these members, it is possible to adjust to obtain the required strength and rigidity by inserting carbon fiber reinforced resin into the gap in a reinforcing manner. become.

  Normally, the vehicle skeleton is composed of steel plates having a plurality of strengths and rigidity. This is because a plurality of types of high-strength steel and ultra-high-strength steel corresponding to the tensile strength are used to satisfy the collision safety standard.

  On the other hand, the present invention can be used when it is difficult to obtain a plurality of types of high-strength steel and ultra-high-strength steel due to the circumstances and environment of the manufacturing plant. In other words, it can be designed to satisfy the strength and rigidity required for each part of the skeleton of the vehicle by using the inner member of this embodiment for a small number of types of high-strength steel and ultra-high-strength steel. It becomes possible.

  The strength and rigidity can be adjusted by changing the thickness of the inner member made of the carbon fiber reinforced resin according to the present embodiment, the direction of the fiber when the resin is manufactured and processed, the material to be synthesized, and the like.

  By carrying out the present invention in this way, an inner member made of a carbon fiber reinforced resin can be obtained even in a situation where only a few types of steel plates are available, that is, a plurality of types of steel plates satisfying the required strength, etc. Therefore, required strength and rigidity can be satisfied.

  Here, although carbon fiber reinforced resin (CFRP: Carbon Reinforced Plastics) is used in the basic embodiment of the present invention, fiber reinforced resin (FRP: Fiber Reinforced Plastics), carbon fiber reinforced thermosetting resin (CFRTS: Carbon Fiber Reinforced Thermosets) and carbon fiber reinforced thermoplastics (CFRTP) may be used.
