Description

A kind of all side beam structure for automobile accessory frame
Technical field
The utility model relates to automobile front chamber body part, especially relates to a kind of all side beam structure for automobile accessory frame.
Background technology
Subframe all side beam is as the absorption cell of automobile front chamber, and it act as increases the intensity of vehicle when there is head-on crash, reduces the central greatest peak of car body collision waveform, to reach the object that alleviates human injury.The passenger protection > > of GB11551-2003 < < manned vehicle head-on crash has stipulated the injury values requirement of occupant's head, neck, chest, thigh, lower leg area.This restriction of rules has increased the performance requriements to constrained system on the one hand, has increased on the other hand the technical requirements to crash-worthiness.Similar vehicle reduces car body collision acceleration/accel for reaching, and conventionally adopts following methods: 1. increasing front deck can conquassation space, such as by increasing front overhang length, or reduces size of engine etc.; 2. optimize longeron crash-worthiness, promote its energy absorption capacity; 3. optimize the collision force-transfer characteristic of front anti-collision beam; 4. driving engine collides sinking technology etc.; Yet above-mentioned improvement project all can not reach the object of desirable reduction car body collision acceleration/accel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of all side beam structure for automobile accessory frame for problems of the prior art, its objective is and reduce car body collision acceleration peak value, and then the extent of injury each position of occupant being caused while reducing vehicle generation head-on crash.
The technical solution of the utility model front connecting panel and rear connecting panel that to be this kind comprise all side beam body and lay respectively at all side beam body two ends for all side beam structure of automobile accessory frame, described all side beam body comprises body upper plate and body lower plate, described body upper plate and body lower plate coordinate the column forming with cavity, and described all side beam body is three sections of linear type structures with two bendings along its length.
The sectional dimension of the one end being connected with front connecting panel on described all side beam body is greater than the sectional dimension of the one end being connected with rear connecting panel on all side beam body, the sectional dimension at the middle part of all side beam body is minimum, and the sectional dimension at two ends is mild transition to middle part sectional dimension.
The yield strength of the panel beating material of described all side beam structure is more than or equal to 280MPa.
The thickness of the panel beating material of described all side beam body is more than or equal to 1.2mm.
The thickness of described front connecting panel and the panel beating material of rear connecting panel is more than or equal to 3mm.
Between described front connecting panel, rear connecting panel and all side beam body, adopt CO 2protect soldered being connected together.
Described body upper plate and body lower plate adopt CO 2protect soldered being connected together.
This kind with said structure has the following advantages for all side beam structure of automobile accessory frame:
1. this kind need not increase front overhang length or reduce size of engine for all side beam structure of automobile accessory frame, need not deliberately go to optimize longeron crash-worthiness, also need not deliberately remove to optimize the collision force-transfer characteristic of front anti-collision beam, need not go to consider whether driving engine sinks, can reach and reduce car body collision acceleration peak value, and then the object of the injury at each position of occupant while reducing vehicle generation head-on crash.
2. simple in structure, easy for installation for all side beam structure of automobile accessory frame of this kind, and the car body collision acceleration peak value reducing in head-on crash process is had to direct effect, and then play protection occupant's effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is arranged on the structural representation on vehicle body.
In Fig. 1-2,1: body upper plate; 2: body lower plate; 3: front connecting panel; 4: rear connecting panel; 5: water tank cross sill; 6: subframe.
The specific embodiment
Fig. 1 is structural representation of the present utility model, and Fig. 2 is that the utility model is arranged on the structural representation on vehicle body.From structure shown in Fig. 1-Fig. 2 in conjunction with, front connecting panel 3 and rear connecting panel 4 that this kind comprises all side beam body and lay respectively at all side beam body two ends for all side beam structure of automobile accessory frame, all side beam body comprises body upper plate 1 and body lower plate 2, body upper plate 1 and body lower plate 2 coordinate the column forming with cavity, and all side beam body is three sections of linear type structures with two bendings along its length, and concrete shape is
