Foreside structure of vehicle

Abstract

Provided is a front region structure of an automobile having a shroud panel supporting structure which can prevent parts being supported by the shroud panel from being damaged at the time of a minor collision, and can maintain the impact absorbing performance of a crash tube at the time of a major collision. To the upper surface 2h, the internal side surface 2i and the lower surface 2u of a middle part in the longitudinal direction of the crash tube 2, fixing surfaces 6h, 6f and 6g which are crash tube side fastening parts of a connecting member 6 are respectively fixed. Then, the shroud panel 20 is fastened to the fastening upper surface 6d and the shroud fastening lower surface 6e which integrally extend forward from the fixing surfaces and are shroud panel side fastening parts extending to the internal side of a vehicle. A hollow part 8a is provided on a connecting part 6b between the crash tube side fastening part and the shroud panel side fastening part. Since the connecting member 6 is fixed to an area within approximately the same plane of the middle part of the crash tube 2, the crushing of the crash tube 2 is made uniform, and the impact absorbing performance can be maintained.

Description

technical field [0001] The present invention relates to a vehicle front structure. Background technique [0002] Regarding the front structure of a vehicle having a front side frame (Front Side Frame), a bumper beam (Bumper Beam) arranged along the vehicle width direction, an extruded pipe (Crush Pipe), and a baffle (Shroud Panel), for example, Japanese Patent Laid-Open 2002-240744 bulletin, according to the disclosed content shown in FIG. 4 , the front structure of the vehicle is equipped with a buffer surface (Bumper face) 106, and a baffle plate 101 arranged behind the buffer surface 106, and a radiator (radiator) 102 , the buffer reinforcement 105, the extruded tube 105a, the flange portion (Flange) 105b of the buffer beam reinforcement member, the front side frame 121, etc., the baffle 101 provided between the above-mentioned left and right extruded tubes 105a passes through the connecting member, and extruded The flange part 105b clampe...

AI Technical Summary

Problems solved by technology

In this case, when there is a slight collision that does not affect the safety of passengers in the vehicle, the buffer reinforcement 105 is crushed along with the extruded tube front side, and retreats to collide with the fender 101, while on the other hand, due to The strength and rigidity of the supporting parts supporting the baffle 101 are improved, making it difficult for the baffle 101 to retreat, and as a result, the parts supported by the baffle 101 are easily damaged, thereby increasing the repair cost of the user

[0005] In addition, if the length of the support portion from the flange portion 105b to the baffle connecting portion 105d continues to be extended, and at the same time the strength and rigidity of the support portion are increased, in the case of the structure shown in FIG. The rear end of the extruded tube 105a extends forward independently. When the extruded tube 105a is crushed from the front end to the rear end to absorb the impact load, the strength and rigidity of the supporting part hinder the impact absorption of the extruded tube. performance, resulting in the failure of the front structure of the vehicle to ensure the safety of passengers
