Background
In recent years, efforts to provide access to sustainable transportation systems that also take account of people in a wealth position, such as elderly people or children, among transportation participants are being actively pursued. In order to achieve the above object, research and development have been conducted to further improve the safety or convenience of traffic through development related to the improvement of the rigidity of the vehicle body.
Conventionally, as a vehicle body structure, a vehicle body structure in which a pair of left and right suspension towers as damper housings are connected to each other via a cross member is known. For example, in patent document 1, by using a cross member as a compressive strength member, the cross member suppresses deformation in the vehicle width direction and the vehicle height direction of the pair of right and left suspension towers, and in particular, can suppress inward tilting in the vehicle width direction, and thus, can improve rigidity of the suspension towers in the vehicle width direction, and can improve steering stability of the vehicle.
However, in patent document 1, there is room for improvement in the connection between the fender and the pylon, and particularly when the fender and the pylon are manufactured in separate processes and fastened and connected in the vertical direction, it is necessary to suppress not only the inward inclination in the vehicle width direction but also the outward inclination in the vehicle width direction. Therefore, in research for improving the rigidity of a vehicle body in order to improve the safety and convenience of traffic, how to further improve the rigidity of a damper housing has been a problem to be solved.

The front-rear direction, the left-right direction, and the up-down direction correspond to the vehicle length direction, the vehicle width direction, and the vehicle height direction, respectively. In the present embodiment, the vehicle front structure 100 refers to a structure disposed in the vicinity of a damper system in a hood in front of a vehicle. A specific structure of the vehicle front structure 100 will be described below with fig. 1 to 3C.
Referring to fig. 1 to 3C, in the present embodiment, a vehicle front structure 100 includes a damper housing 110, an upper member 120, and an instrument panel upper member 130. Specifically, as shown in fig. 1, in the present embodiment, the upper member 120 and the damper housing 110 are configured as a pair of right and left members. The shock absorber housing 110 supports load inputs from a suspension shock absorber (not shown), wherein the shock absorber housing 110 and the suspension shock absorber are part of a suspension system of a vehicle. The upper member 120 is provided on the vehicle width direction outer side of the damper housing 110, and extends in the vehicle length direction. In the present embodiment, the upper member 120 is, for example, a part of a fender. Further, as shown in fig. 1, in the present embodiment, the dash upper member 130 connects the pair of left and right upper members 120, and the dash upper member 130 includes a dash upper body 131 and a cross member 132. Further, as shown in fig. 1, the instrument panel upper body 131 extends in the left-right direction, and the left and right end portions of the instrument panel upper body 131 are connected to the rear side portions of the left and right pair of upper members 120, respectively. On the other hand, the cross member 132 protrudes below the instrument panel upper body 131 and connects the pair of right and left damper housings 110.
More specifically, as shown in fig. 2A, in the present embodiment, the damper housing 110 includes an upper member fastening face portion 111, a wall portion 112, and a first flange portion 113, wherein the upper member fastening face portion 111 is used to fasten and fix the upper member 120. The wall portion 112 extends downward in the vehicle from the outer end portion of the upper member fastening surface portion 111 in the vehicle width direction, and the first flange portion 113 extends outward in the vehicle width direction from the wall portion 112 toward the lower surface of the upper member 120. On the other hand, as shown in fig. 2B, in the present embodiment, the upper member 120 includes a second flange portion 121 and a damper case fastening surface portion 122, wherein the second flange portion 121 extends inward in the vehicle width direction toward the upper member fastening surface portion 111, and the damper case fastening surface portion 122 is used to fasten and fix the damper case 110.

For example, the damper housing 110 and the upper member 120 may be fastened by a fastener BT such as a bolt. In this way, by the damper housing 110 and the upper member 120 being fastened and fixed so as to be sandwiched between the upper surface S111 of the upper member fastening surface 111 on the vehicle width inner side and the lower surface S122 of the damper housing fastening surface 122 on the vehicle width outer side, not only the inward inclination of the damper housing 110 in the vehicle width direction but also the outward inclination thereof in the vehicle width direction can be suppressed. Further, the shock absorber housing 110 and the upper member 120 are fastened and fixed to the surfaces that abut against each other by the fasteners BT in the vehicle height direction, respectively, and have the characteristic of easy attachment and detachment, and can prevent the suspension system at the front of the vehicle from tilting by the design of the strength and the load durability of the rough road surface. Further, the first flange portion 113 and the second flange portion 121 connecting the damper housing 110 and the upper member 120 are provided as brackets at positions where shear forces are easily transmitted to members having high rigidity such as the damper and the lower member of the vehicle front structure 100, so that loads can be smoothly transmitted to the positions of the members having high rigidity, and further the rigidity of the vehicle front structure 100 can be improved.
On the other hand, as shown in fig. 3A and 3C, in the present embodiment, the dash upper body 131 and the cross member 132 form a closed cross section. For example, the instrument panel upper body 131 may be welded with the cross member 132 to form a closed cross section. In this way, by arranging the dash upper body 131 and the cross member 132 in a closed cross section, the rigidity of the dash upper member 130 can be increased, and tilting of members such as the damper housing 110 and the suspension damper to the inside in the vehicle width direction in the suspension system of the vehicle can be further suppressed.
As described above, in the vehicle front portion structure according to the present utility model, the damper housing and the upper member are fastened and fixed so as to be sandwiched between the upper surface on the vehicle width inner side and the lower surface on the vehicle width outer side, so that not only the inward inclination of the damper housing in the vehicle width direction but also the outward inclination thereof in the vehicle width direction can be suppressed. Further, the damper housing and the upper member are fastened and fixed to the surfaces abutting each other by the fasteners in the vehicle height direction, respectively, and have the characteristic of easy attachment and detachment, and can prevent the suspension system at the front of the vehicle from tilting by the strength and the load durability of the rough road surface. The first flange portion and the second flange portion connecting the damper housing and the upper member are provided as brackets at positions where shear force is easily transmitted to members having high rigidity such as the damper and the lower member of the vehicle front structure, so that load can be smoothly transmitted to the positions of the members having high rigidity, and further rigidity of the vehicle front structure can be improved.
