Definitions
- the present invention relates to a vehicle end structure constructed near the front end or rear end of a vehicle structure.
- the monocoque structure is a structure in which an old frame and body are integrally formed of steel plates, and is often used in passenger cars.
- the frame structure is a body placed on a structure called a robust frame.
- the frame structure is often used for trucks with excellent strength and heavy loading load or heavy vehicle weight, and for RV vehicles where the input from the road surface increases when driving on rough roads.
- the truck has a larger body and therefore a higher bamba position.
- RV vehicles the height of the vehicle is raised to avoid road surface interference on rough roads, and large-diameter tires are used to improve driving performance on rough roads. Become.
- an under protector is attached further below the bumper position (see, for example, Japanese Patent Laid-Open Publication No. 2000-73-0590).
- the bumper of the monocoque car and the under protector of the frame car collide with the monocoque car with the lower Bamba position and the frame car with the higher Pampa position ⁇ , and move to the bottom of the monocoque car frame.
- the crushable zone of a monocoque car is effectively deformed to absorb energy during a collision.
- an object of the present invention is to provide a vehicle end structure capable of more reliably receiving a load at the time of collision in a frame-structured vehicle body.
- a vehicle end structure is constructed in the vicinity of a front end or a rear end of a vehicle structure, and includes a pair of vehicle body frame members extending in the front-rear direction of the vehicle body, and ends of the pair of frame members.
- Bumper reinforcements installed on the base, a pair of brackets that protrude outward from each frame material on the vehicle center side than the ends of the pair of frame materials, and extend downward from each bracket
- both ends of a cross member member (a member corresponding to an under protector or the like) are joined to a frame material using a bracket and an outer biller member. For this reason, deformation at the time of the collision of the portion outside the inner pillar member is suppressed, and it is possible to effectively prevent the collision object colliding with the offset from entering the side of the vehicle. Further, not only the collision force applied to the pair of inner pillar members but also the collision force applied to the outside of the inner pillar member can be received by the pair of frame materials as the structural material via the bracket and the outer pillar member. Become. As a result, a vehicle having this vehicle end structure can achieve a good collision performance by receiving a collision load with the structure.
- vehicle end structure according to the present invention is the vehicle end structure described above, wherein the pair of brackets serve as a mount portion of a body attached on the frame material. It is a feature.
- a bracket for mounting the body is used to connect the vicinity of the end of the cross member member to the frame material. Therefore, as a new member, only one pair of outer blade members should be prepared. That's fine. Therefore, the vehicle end structure of the present invention can be constructed with a space-efficient and simple structure.
- the vehicle end structure according to the present invention is characterized in that, in the vehicle end structure described above, the cross member member is constructed as an under protector that protects the lower surface of the vehicle body from contact with the road surface.
- the vehicle end structure of the present invention can be constructed while suppressing an increase in the number of parts.
- the vehicle end structure according to the present invention is characterized in that, in the vehicle end structure described above, the vehicle end structure includes a pair of energy absorbing members that are coupled to the front end portion of each frame material and are less rigid than the frame material. Yes.
- the energy absorbing member is less rigid than the frame material, in the case of a light collision (including offset collision), only the energy absorbing member is deformed and absorbs the energy at the time of the collision. .
- frame parts can be used even after a collision, reducing repair costs.
- FIG. 1 is a perspective view showing an embodiment of a vehicle end structure according to the present invention.
- FIG. 2 is a cross-sectional view of the vehicle end structure of FIG. 1 (a cross-sectional view of the vicinity of the front end of a pair of frame members taken as a cut surface and viewed from the front side of the vehicle).
- Fig. 3 is a plan view showing the situation at the time of collision.
- FIG. 1 shows an enlarged perspective view of the main part of the vehicle both ends structure of the present embodiment.
- Fig. 2 shows a pair of frame materials described later.
- a cross-sectional view cross-sectional view of the vehicle from the front side to the rear side
- 1 and 2 show the vehicle end structure on the front side.
- the vehicle having the both-ends structure of the present embodiment is a vehicle having a frame structure. As shown in FIG. 1, a pair of frame members 1 constituting the frame are arranged substantially parallel to the vehicle longitudinal direction.
- Crash boxes 2 are coupled to the tip portions of the pair of frame materials 1, respectively.
- the crash box 2 has a lower rigidity than the frame material 1 and is provided for the purpose of absorbing energy during a light collision by being crushed during a relatively light collision.
- a bumper reinforcement 3 is coupled to the most advanced portions of the pair of frame members 1 (via the crash box 2).
- the bumper reinforcement 3 is provided for the purpose of transmitting the load acting on the front surface of the vehicle in the event of a vehicle collision to the frame material 1 (through the crash box 2).
- brackets 4 for fixing the body placed on the frame to the frame are coupled to the vicinity of the front ends of the pair of frame members 1.
- Each of the pair of brackets 4 is directed outward with respect to the frame material 1 and coupled to each frame material 1.
- Each bracket 4 has a bolt hole that is used when the body is fixed.
- An outer blade member 5 is coupled to the outer end of each bracket 4 downward.
- the cross member member 6 is constructed so that the lower end of a pair of outer-biller one member 5 may be connected. Further, the cross member 6 is also coupled to the tip of each inner villa member 7 coupled downward to the lower surfaces of the pair of frame members 1. That is, the cross member 6 is coupled to each frame material 1 by a pair of inner pillar members 7, a pair of outer pillar members 5, and a bracket 4.
- the upper end of the outer biller member 5 is coupled to the outer end of the bracket 4, and the lower end of the outer biller member 5 is the distance in the vehicle width direction of the pair of frame members 1.
- the vertical position of the cross member member 6 is set to the bumper height of a normal passenger car or the like.
- Figure 3 shows the vehicle end structure at the time of a vehicle collision.
- Fig. 3 schematically shows only the structural part. Shown in the upper part of FIG. 3 is a front portion of a vehicle provided with the vehicle end structure of the above embodiment.
- the lower part of Fig. 3 shows the front part of a monocoque passenger car. Both cars are in offset collision.
- the passenger car has a structure in which a bumper reinforcement 9 is coupled to the front ends of the pair of side members 8.
- the crash box 2 on the right side of the vehicle having the vehicle end structure described above is crushed.
- the right side of the passenger car is also deformed.
- the bumper positions of the two cars are not exactly the same, and the bumper position of the passenger car is lower, so the front part of the passenger car is from the bumper reinforcement 3 of the vehicle with the vehicle end structure described above. Has also entered the back.
- the cross member member 6 described above is prevented from entering backward.
- the outer part of the inner member 7 of the cross member member 6 is connected to the frame member 1 as a structural member by the outer blade member 5 and the bracket 4, the inner member 7 of the cross member member 6. Backward bending of the outer part is suppressed. For this reason, the load at the time of the collision is effectively received even at the portion outside the inch member 1 of the cross member member 6. As a result, for the passenger car, the cross member member 6 effectively functions as a reaction force surface, so that the crushable zone of the front portion of the vehicle can be effectively deformed and the kinetic energy at the time of collision can be absorbed effectively.
- the prevention of sneak is also effective in improving the collision performance (collision energy absorption performance).
- the frame material 1 is deformed by the load input to the frame material 1 due to the collision and absorbs the kinetic energy at the time of the collision.
- a vehicle having a frame structure has a situation in which it is difficult to ensure a wide interval between the pair of frame members 1, so that the present invention can be used effectively.
- the cross member member 6 as described above When the cross member member 6 is provided to almost the full width of the vehicle (if the bracket 4 is not connected to the frame material 1 with the blade, the blade 1 and the member 5), the cantilevered portions at both ends become long. There is a tendency to end up. (Of course, from the viewpoint of receiving a collision load at the time of a vehicle collision, it is preferable to provide the cross member member 6 to the full width of the vehicle as much as possible.) If the cantilevered portion becomes long, the load at the time of the collision can be reliably received. The portion of the cross member member 6 that can be formed is only between the pair of frame members 1 (inner pillar members 7). For this reason, the energy at the time of collision cannot be absorbed effectively. According to the present invention described above, this can be avoided.
- the vehicle end structure is constructed as the vehicle front portion.
- the vehicle end structure may be constructed as the vehicle rear portion.
- the cross member member
- the cross member member may be constructed as an under protector that protects the lower surface of the vehicle body from contact with the road surface.
- the vehicle in the present invention includes a towing vehicle (such as a container portion).
- both ends of the cross member member are coupled to the frame material using the bracket and the outer villa member, so that the inner villa member is also deformed at the time of the collision of the outer portion.
- the impact force applied to the pair of inner biller members is also applied to the pair of frame materials as the structural material via the bracket and the outer biller member. Can be made. Therefore, according to this vehicle end structure, it is possible to reliably receive the load at the time of collision. As a result, a vehicle having this vehicle end structure can receive a collision load by the structure and realize good anti-collision performance.
