Problems solved by technology

[0007] However, in the conventional vehicle body side panel as described above, since the impact absorbing member having a plurality of ribs at equal intervals is arranged inside the center pillar, when the vehicle body begins to deform due to a side collision, Due to uneven contact between the outer panel and each rib, the impact absorption effect may not be fully exerted, therefore, further improvement in realizing the improvement of the impact absorption function is desired

no. 1 approach

[0031] figure 1 The body side panel BP shown has: a metal panel (outer panel) P1 forming one main surface of the body side panel BP; forming the other main surface of the body side panel BP and forming a space therebetween Another metal panel (inner panel) P2; and a reinforcing resin member R integrally formed with a metal panel P1 in space.

[0032] The material of the metal panels P1 and P2 is not limited, but as an example, it is an aluminum alloy which is advantageous for weight reduction, and is formed into a predetermined three-dimensional shape by pressing a blank. The metal panels P1 and P2 are then joined to each other through processes such as spot welding, and form the body side panel BP together with the resin member R.

[0033] The material of the resin component R is not limited, and the thermoplastic resin (CFRTP) is reinforced with discontinuous carbon fiber, and can be integrally formed on a metal panel P1 by injection molding or resin stamping. The resin me...

[0068] Figure 5 with Image 6 In indicates the body side panel BP of the main part, especially as Image 6 As shown, the distance W1 between one metal panel P1 and the other metal panel P2 in the sill portion SL (the width of the space A) is greater than the distance W2 between the one metal panel P1 and the other metal panel P2 in the center pillar portion CP. .

[0069] Furthermore, the body side panel BP is structured such that, with respect to the resin member R, the spacing ratio from the front end of the connecting rib of the rocker portion S1 to the other metal panel is from the front end of the connecting rib of the center pillar to the other metal panel. The interval between the other metal panels is large.

[0070] More specifically, as Image 6 As shown, the distance S1 (S1a) of the body side panel BP from the front ends of the rocker upper side connecting rib 12A and the rocker lower side connecting rib 12B to the other metal panel P2 is smaller than that from...

no. 3 approach

[0073] exist Figure 7 with Figure 8 In body side panel BP of the main part indicated in , with respect to resin member R, each connecting rib has a structure with different intervals and thickness dimensions from the front end to the other metal panel P1, and the smaller the interval, the larger the thickness dimension.

[0074] More specifically, in the vehicle body side panel BP of the present embodiment, particularly as Figure 8 As shown, the rocker upper connecting rib 12A has a width T1 larger than a width T2 of the other connecting ribs 11B, 12B. The distance S1 ( S1 a ) from the front end portion of the rocker upper connection rib 12A to the other metal panel P2 is smaller than the distance S1 ( S1 b ) of the other connection ribs 11B, 12B.

[0075] When the body side panel BP having the above structure receives a side collision, initially the rocker upper connecting rib 12A having the largest width T1 collides with the other metal panel P2 to absorb the initial im...

Abstract

A body side panel (BP) comprises: one metal panel (P1); another metal panel (P2) that forms an empty space (A) between the one metal panel (P1) and the other metal panel (P2); and a resin member (R) that is integrally formed on the one metal panel (P1). The resin member (R) has: connecting ribs (11A, 11B, 12A, 12B) which are continuous along the front edge and the rear edge of a center pillar portion (CP), and the upper edge and the lower edge of a sill portion (SL), respectively; and lower cross ribs (14) that are arranged in the region where the lower end of the center pillar portion (CP) and the sill portion (SL) cross each other. The spacing (S1) between the leading ends of the connecting ribs (11A, 11B, 12A, 12B) and the other metal panel (P2) is smaller than the spacing (S2) between the leading ends of the lower cross ribs (14) and the other metal panel (P2). The impact energy of a side impact is released in two stages, and thus the impact absorption function is improved.

Description

technical field [0001] The present invention relates to a vehicle body side panel, and more particularly, to a vehicle body side panel in which a metal panel and the other metal panel are reinforced with a resin member. Background technique [0002] As a conventional vehicle body side panel, it is described in Patent Document 1 under the name of a vehicle impact energy absorbing structure. Patent Document 1 describes a structure in which a shock absorbing member is arranged between an outer panel and an inner panel in a center pillar portion of a vehicle body side panel. The shock-absorbing member is composed of a plurality of ribs combined in a lattice, and is fixed to the inner panel with the ribs facing the outer panel side. [0003] In this shock absorbing member, ribs having main surfaces facing the front-rear direction and ribs having main surfaces facing the up-down direction are arranged at equal intervals, and absorb impact energy accompanying deformation of the ri...
