In view of the collision safety requirements, the utility model has a structural design form of two types of failure modes. When a collision occurs, the power assembly will fall together with the damaged sub-frame; The U-shaped structure is the U-structure longitudinal beam, and the longitudinal beam is designed with a collision induction groove structure, which is easy to realize that the sub-frame body automatically collapses after the vehicle collides, and ensures the safety of the occupants in the vehicle to the greatest extent.
Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of automobile accessory frame.
Background technology
Because subframe carries dynamic assembly, suspension system and steering swivel system, so each system needs subframe that enough bulk strengths and integral rigidity are provided, and for satisfying this demand, during the design subframe, often adopts high tensile steel plate and and complicated structure in the industry.But high strength material steel plate deep drawability is poor, and complicated auxiliary frame structure is unfavorable for making and loss of weight.In addition, recognize gradually in the industry that existing automobile accessory frame can not effectively absorb the ability in the collision process, proposed two class subframe failure modes, to improve member's collision safety.
A kind of inefficacy energy-absorbing modes namely is can separate with vehicle body immediately at the vehicle collision Rear secondary frame for vehicle, and dynamic assembly falls.Be that the 52-11717 Japanese Utility Model is announced a kind of subframe fastener such as the patent No., utilize the bolt connecting bridge fracture of subframe and the vehicle body support of supporting suspension arm, so that subframe separates with vehicle body.
Another kind of inefficacy energy-absorbing modes namely is to produce crumple at the vehicle collision Rear secondary frame for vehicle at fore-and-aft direction.As disclosed among the existing Chinese patent 202046368U, in subframe front end extra soldered one collision energy-absorbing framed structure.These framed structure both sides all connect with 2 U-shaped punching press panel beating button weldings and form, and frame front end is the crossbeam of a long 500mm of surpassing.This structure not only input cost is higher, and so that subframe weight greatly increase.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of subframe of thin plate welding cavity truss-like band crash safety functions, when this subframe bumps, hold-down bolt between subframe and the vehicle body is cut off, dynamic assembly will fall with destroyed subframe, and automatic buckling occurs in this cognition of subframe, has farthest ensured passenger's safety.
The utility model is achieved in that a kind of subframe of thin plate welding cavity truss-like band crash safety functions, comprise that right vertical beam assembly, left longeron assembly, front cross rail assembly and rear cross beam assembly four parts consist of, described right vertical beam assembly, left longeron assembly, front cross rail assembly and rear cross beam assembly are fixedly linked becomes a framework, this framework is the cavity truss structure, the two ends of front cross rail assembly and rear cross beam assembly are provided with the vehicle body mounting hole, be fastenedly connected by hold-down bolt and vehicle body, front cross rail assembly middle part is provided with a pair of dynamic assembly support.
Described right vertical beam assembly and left longeron assembly are arcs of recesses low between the senior middle school of two.
The front end of described right vertical beam assembly and left longeron assembly is provided with induces groove.
The described groove of inducing is Long Circle.
The cavity truss structure of the subframe of the utility model thin plate welding cavity truss-like band crash safety functions has larger integral rigidity and higher resistance to overturning, and is simple in structure, cheap for manufacturing cost; When bumping, the hold-down bolt between subframe and the vehicle body is cut off, and dynamic assembly will fall with destroyed subframe; It is U structure longeron that the subframe left-right longeron all presents concave structure low between the senior middle school of two, and longeron design collision-induced groove structure, and after being easy to realize collision happens, subframe body generation automatic buckling has farthest ensured passenger's safety.
