Abstract
The invention relates to a car component, in particular to a car middle frame. The car middle frame comprises a middle frame inner plate and a middle frame outer plate which are parallel to each other. The middle frame inner plate and the middle frame outer plate are both one-time hot stamping steel plates, an inner plate cross beam is connected with the outer edge of a corresponding outer plate cross beam, an inner plate longitudinal beam is connected with the outer edge of a corresponding outer plate longitudinal beam, and therefore a hollow cavity with openings in the front end and the rear end is formed inside the whole middle frame. According to the car middle frame, the middle frame inner plate and the middle frame outer plate are formed through one-time hot stamping, the overall intensity of the middle frame can be strengthened, and due to the fact that the longitudinal beams and cross beam pieces are formed by stamping, the connecting strength of the longitudinal beams and the cross beams is high, and the anti-collision performance of the whole middle frame is good.

Middle vehicle frame outside plate and middle vehicle frame inner panel are one-shot forming part, form vehicle frame in integral type, longitudinal and cross beam forms by punching press, Joint strenght between longitudinal and cross beam is high, weight be lighter than in traditional self-supporting body, by section bar, made in vehicle frame, middle vehicle frame outside plate and middle vehicle frame inner panel with inner panel crossbeam and edge-to-edge between outside plate crossbeam, inner panel longeron with together with edge-to-edge's laser full weld between outside plate longeron, reduced and welded weak appearance, and the strength of material at laser welding place is better than mother metal; In integral type, vehicle frame only has two parts to form, and has reduced the quantity of part, is conducive to improve allowance control precision, machine automatization rate, reduces the input of the attendant equipments such as production site, mould, cubing, fixture.
Preferably, middle vehicle frame inner panel comprises inner panel front cross rail, inner panel center member and the inner panel after cross member of arranging in turn from front end to end, and between inner panel front cross rail and inner panel center member, be symmetrical arranged 2 inner panel front side members, between inner panel center member and inner panel after cross member, be symmetrical arranged longeron in 2 inner panels, and in the end symmetrical of inner panel after cross member, 2 inner panel tail booms be set.
In inner panel front side member and inner panel, longeron is all perpendicular to inner panel center member, and inner panel front side member and longeron in corresponding inner panel are point-blank.
Preferably, middle vehicle frame outside plate comprises outside plate front cross rail, outside plate center member and the outside plate after cross member of arranging in turn from front end to end, and between outside plate front cross rail and outside plate center member, be symmetrical arranged 2 outside plate front side members, between outside plate center member and outside plate after cross member, be symmetrical arranged longeron in 2 outside plates, and in the end symmetrical of outside plate after cross member, 2 outside plate tail booms be set;
In outside plate front side member and outside plate, longeron is all perpendicular to outside plate center member, and outside plate front side member and longeron in corresponding outside plate are point-blank.
Distance between 2 inner panel tail boom front ends is less than 2 distances between inner panel tail boom end, and 2 inner panel tail booms are splayed, is convenient to be connected with the miscellaneous part of vehicle.
Distance between 2 outside plate tail boom front ends is less than 2 distances between outside plate tail boom end, and 2 outside plate tail booms are splayed, is convenient to be connected with the miscellaneous part of vehicle.
The present invention is vehicle frame in a kind of car, by a drop stamping, form middle vehicle frame inner panel and middle vehicle frame outside plate, can add the bulk strength of persistent erection vehicle frame, and because longitudinal and cross beam forms by punching press, the Joint strenght of longeron and cross-member is high, and in integral body, the crashworthiness of vehicle frame is good.
