Frame structure and vehicle

Abstract

The utility model provides a kind of frame structure and vehicle, frame structure includes: stringer, first reinforcing member and second reinforcing member, first reinforcing member is along the length direction of stringer and is connected with stringer, in the length direction of stringer, first reinforcing member and at least part of the region of stringer are enclosed to form closed loop type cross section;Second reinforcing member is located with first reinforcing member on the same side of stringer, and is connected with stringer, and second reinforcing member and first reinforcing member are arranged in the length direction of stringer with interval.It can improve the energy absorption efficiency of stringer and the stability of itself structure that first reinforcing member and stringer form closed loop type cross section, reduce the possibility of stringer when being extruded to fall down;Meanwhile, form inducing opening between first reinforcing member and second reinforcing member, so that stringer can bend and absorb energy at inducing opening when collision occurs, to reduce the acceleration of whole vehicle, further improve the safety performance of vehicle.
