Structure for reinforcing shock absorber housing
A structure for reinforcing a shock absorber housing includes a shock absorber housing connecting a shock absorber mounting panel and a front side member. A front fender apron inner panel connects the shock absorber mounting panel and the front side member. The front fender apron inner panel is coupled to an outer surface of the shock absorber housing and overlapped with a portion of the shock absorber housing to form a wheel house with the shock absorber housing. An extension panel is connected from a side of the overlapped portion of the shock absorber housing and the front fender apron inner panel to a sub-frame mounting portion of the front side member.
1. A structure for reinforcing a shock absorber housing of a vehicle, comprising:
a shock absorber housing connecting a shock absorber mounting panel and a front side member;
a front fender apron inner panel connecting the shock absorber mounting panel and the front side member, the front fender apron inner panel coupled to an outer surface of the shock absorber housing and overlapped with a portion of the shock absorber housing to form a wheel house with the shock absorber housing; and
an extension panel connected from a side of the overlapped portion of the shock absorber housing and the front fender apron inner panel to a sub-frame mounting portion of the front side member,
wherein the shock absorber housing and the front fender apron inner panel have a plurality of closed sectional surfaces formed by a plurality of forming portions, which outwardly protrude from each of the shock absorber housing and the front fender apron inner panel, at the overlapped portion, and
wherein the plurality of forming portions extend to both inner sides of the shock absorber mounting panel and to the front side member.
2. The structure of claim 1 , wherein the plurality of forming portions protrude in a height direction from the shock absorber housing and the front fender apron inner panel.
3. The structure of claim 1 , wherein each of the plurality of closed sectional surfaces has a polygon shape having more than four angles.
4. The structure of claim 1 , wherein the shock absorber housing and the front fender apron inner panel are coupled by spot welding along an edge of the plurality of forming portions.
5. The structure of claim 1 , wherein the extension panel includes: an upper coupling part coupled to the plurality of forming portions and covering the plurality of forming portions of the front fender apron panel; and a lower coupling part coupled to an outer surface of the front side member and the sub-frame mounting portion.
6. The structure of claim 1 , wherein the extension panel is coupled to an outer surface of the front fender apron inner panel and the front side member along an edge of the extension panel.
7. The structure of claim 1 , wherein the extension panel has a Y-shape.
