[0042] [1. Structure]

[0043] First, the peripheral structure of the underrun protector will now be described according to the first embodiment.

[0044] Such as figure 1As shown, the underrun protector 10 is attached to the lower portion of the front portion 1a of the vehicle frame 1 such that the longitudinal sides of the underrun protector 10 extend in the width direction of the vehicle. The underrun protector 10 is connected to a plurality of brackets 5 , 5 formed on left and right portions of the front portion 1 a of the vehicle frame 1 , respectively.

[0045] [1-1. Surrounding structure]

[0046] Hereinafter, the structures of the frame 1 and the bracket 5 will now be described in sequence.

[0047] [1-1-1. Frame]

[0048] A frame 1 of a vehicle is a so-called ladder frame and includes a pair of side frames (side members) 2 , 2 and a cross member (cross member) 3 .

[0049] The side frames 2, 2 are arranged along the front-rear direction of the vehicle with a pred...

Abstract

An underrun protection structure is provided which is low in weight, low in cost and avoids buckling. In the structure of the underrun protector (10) coupled to a plurality of brackets arranged at the front portion or the rear portion of the vehicle frame, arranged on the distal end side in the vehicle front-rear direction A distal panel (20) made of a channel-shaped steel plate is bonded to a proximal panel (30) arranged on the proximal side in the vehicle front-rear direction and made of a channel-shaped steel plate at a plurality of joint overlaps (91). , at each joint overlap, the edges (22a, 23a, 32a, 33a) of the corresponding flanges (22, 23, 32, 33) overlap; In the joint area where the respective brackets of each bracket are combined, a reinforcing panel made of steel plate is arranged in the hollow body so that the reinforcing panel is in contact with the inner face of one of the proximal panel (30) and the distal panel (20) And in contact with the joint overlapping portion (91), so that the structure has a multi-panel portion (85) formed of three or more overlapping panels.

Description

technical field [0001] The present invention relates to a structure of an underrun protection device that suppresses a vehicle of a shorter height from getting under another vehicle of a higher height in the event of a collision between vehicles. Background technique [0002] In order to prevent a shorter vehicle (such as a passenger car or minicar) from getting under the front or rear portion of a taller vehicle (such as a motor truck), equipped with a front section mounted on the frame Or vehicles with a high height of the underrun protection under the rear section are already in practical use. [0003] The underrun protection requires at least sufficient strength and rigidity to inhibit another vehicle from getting under the vehicle to which the underrun protection is installed. Unfortunately, underrun guards formed of steel, which have been widely used in vehicles, result in an increase in the weight of the vehicle. [0004] In view of the above problems, an underrun p...
