Abstract

PURPOSE:To eliminate flange projected from the outside of a bumper and increase the cross-section of a hollow portion by using a bumper reinforcement in which upper and lower half members are fitted closely to each other and the laminated portions of both sides of them are bonded to form a box type closed-section beam. CONSTITUTION:A bumper comprises a cover member 10, a shock absorbing member 20, and beam-shaped reinforcement 30, and an air intake 40 extended from the cover member 10 is arranged under the reinforcement 30. The reinforcement 30 is composed of an upper half member 311 of FRP in channel form provided with short side portions 312 and a lower half member 321 in channel form provided with long side portions 322. The top of both side portions of the lower half member 321 is fitted closely into a close-fitting recess 313 formed at both ends of the upper half member 311 and sticked with adhesive to form a box type closed-section beam. At the top of the upper half member 311 where the cover member 10 is fixed, a projected mounting portion 314 is integrally formed to fix it to the cover member 10 by a fastener 6'.

(Means for Solving Problem 11) The present invention provides a bumper reinforcement without a protruding flange portion by making the two parts to be joined have a U-shaped cross section, and fitting and joining the two parts facing each other vertically. It was created with a focus on the fact that it can be manufactured, and is a box-shaped closed section bumper reinforcement made of FRP in which the bumper is formed by assembling the energy absorbing member and the skin member. The upper half member and the lower half member are faced to each other and the abutting portions are fixed in contact with each other, and the upper surface and/or the upper half member are fixed.
Alternatively, there is a plastic bumper reinforcement in which a skin member mounting surface is integrally formed on the lower surface of the lower half member.

In the present invention, the fitting form of the upper and lower half members is such that both sides of the lower half member are longer than both sides of the upper half member, in order to ensure the function of the bumper that transmits impact from the front to the rear.
Preferably, it is fitted inside the upper half. Furthermore, since the present invention employs a fitting form of upper and lower half members, it is desirable to provide a positioning member so that positioning can be performed using this. As a method for joining these two members, adhesion using an adhesive, welding using ultrasonic waves or high frequency waves (however, not suitable for thermosetting resin), a method using mechanical fastening, etc. may be employed.

(Function) According to the present invention, the upper and lower half members are fitted facing each other, and the overlapping portions on both sides are joined and fixed to form a box-shaped closed cross-sectional beam shape, so that the bumper reinforcement protrudes from the outer shape of the bumper reinforcement. Two parts can be joined without using a flange, and even if the cross-sectional area of the cavity of the bumper reinforcement is increased, the air passage below the bumper reinforcement will not be obstructed. Further, since the mounting surface of the skin member is integrally formed on the upper surface of the upper half member and/or the lower surface of the lower half member, the skin member can be mounted without using a retainer.
