Abstract
The invention discloses a car front-upper member bracket assembly comprising a bracket and a bracket connecting piece, wherein the main structure of the bracket is a strip-shaped piece, three welding flangings are respectively extended from the upper end and two sides of the main structure, and a welding perforation is arranged in the middle of the main structure. The main structure of the bracket connecting piece is a strip-shaped piece shorter than the bracket, three welding flangings are respectively extended from the upper end and two sides of the main structure, and a welding perforation is arranged on the main structure. The lower half parts of the welding flangings at the two sides of the bracket are welded together with lateral ends of a longitudinal beam of an engine cabin, and the upper half parts and the welding flanging at the upper end are welded together with the welding flanging at the upper end of the bracket connecting piece and the upper half parts of the welding flangings at the two sides to form a box type structure; and the lower half parts of the flangings at the two sides of the bracket connecting piece are welded together with the upper end of the longitudinal beam of the engine cabin. The assembly adopts two parts to form a box type structure so as to be welded together with the collision longitudinal beam in the engine cabin, so that the welding relation is simple, the parts are fewer, not only is the installation requirement met, but also the performance demand is met.
Description
Technical field
The present invention relates to a kind of body construction in auto body field, be specifically related to the preceding upper member bracket assembly of a kind of automobile.
Background technology
The rigidity (torsional stiffness, bending stiffness) of automobile body-in-white welding assembly is to estimate one of body in white welding assembly performance very important index.In order to guarantee to reach these expected values, just need good body construction design.Machinery space welding assembly is requisite part of body in white lower body; except the important task of the heart-driving engine of bearing automobile; still protect the important barrier together of pedestrains safety; it is particularly important that its structure design seems; not only to do corresponding design, and will consider this one side of collision safety at rigidity.The upper member carriage is the very important and requisite part in front portion, motorcar engine cabin before the automobile, says that from function it one is that condenser to automobile provides attachment point, the 2nd, provide mounting hole site to head light.Good design can guarantee machinery space cross bending mode, satisfies the demand of collision.
The upper member carriage probably has following several before the present automobile: a kind of is absolute construction, is a U-lag structure substantially, welded together with the longeron in the machinery space.Can realize the installation of condenser and the installation of head light on the function.Though this structure part is few, the welding relation is simple, can not satisfy the cross bending mode of machinery space well.Because with regard to a part, there is not the reinforcement auxiliary component of attaching parts and so on.The leading portion intensity of whole engine bin is also poor.Second kind is sectional type, in the longeron upper end of machinery space a preceding upper member carriage is arranged, and in order to satisfy the mounting hole site demand of upper end of condenser, has an auxiliary attaching parts to play booster action simultaneously.Also have a preceding upper member carriage in the longeron lower end, in order to satisfy the mounting hole site demand of condenser lower end, the bottom also has reinforcement to assist reinforcement simultaneously.This constructional delails is more, has four, and the welding relation is complicated, and cost is also high.
As can be seen, it is few that good preceding upper member carrier structure need satisfy the part number, and the welding relation can not be too complicated, satisfy the installation requirements (condenser, head light) of parts, satisfies the cross bending mode demand and the collision demand of machinery space.Therefore, the advantage of comprehensive top two kinds of structures, single separate bracket add connection assist and just can yet be regarded as and a kind ofly select preferably.
Summary of the invention
The technical problem to be solved in the present invention provides the preceding upper member bracket assembly of a kind of new automobile, adopt less part and simple structure, satisfy the especially cross bending mode of machinery space front end of vehicle body, the demand of needs engine nacelle curb girder compressive deformation when satisfying auto against in addition.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
Upper member bracket assembly before a kind of automobile comprises carriage and carriage attaching parts two large divisions.
Wherein the upper member carriage comprises agent structure before the automobile, and three welding flange that extend out above agent structure weld via hole in addition above the agent structure.Agent structure is an elongate member, takes the shape of the letter U substantially, and respectively there are two bigger welding flange both sides, and there is a less welding flange upper end.Be furnished with two bigger welding via holes above the agent structure.Wherein, the latter half of the welding flange that both sides are bigger and the longeron side of machinery space are welded together, and that less welding flange of the first half and upper end and the box-packed structure of carriage attaching parts formation welded together.The welding via hole mainly works to beat solder joint.
The carriage attaching parts comprises agent structure, three welding flange that also extend out from the left and right sides and upper end above agent structure.Agent structure is an elongate member shorter than carriage, and is V-shaped substantially, and three flange of these three flange and preceding upper member carriage and the upper end of machinery space longeron are welded together.The first half of flange and welding flange and the upper end welding flange of carriage attaching parts and the box-packed structure of the first half formation welded together of both sides welding flange of upper end are welded in the both sides that are specially carriage, and the latter half of two side flangings of carriage attaching parts is then welded together with the upper end of machinery space longeron.In addition, welding via hole position is also made sex seduction on agent structure top, mainly plays a part to beat solder joint, and for proof strength, this welding via hole is the flange hole.In order to satisfy the collision demand, specially on agent structure, arranged a reinforced rib, this reinforced rib groove structure that takes the shape of the letter U, and opening is upwards.
As seen, this assembly adopts two parts all to become the collision longeron in box-packed structure and the machinery space welded together, and the welding relation is simple, and part is less, has not only satisfied installation requirements, and has satisfied performance requirement.
