Abstract
The utility model discloses a body-in-while front longitudinal beam strengthening structure comprising a front portion front strengthening plate and a front portion rear strengthening plate, wherein the front portion front strengthening plate and the front portion rear strengthening plate are arranged in a cavity formed by buckling combination of a front longitudinal beam front portion and a front longitudinal beam outer plate. The body-in-while front longitudinal beam strengthening structure is characterized by further being provided with a rear portion strengthening plate, wherein the rear portion strengthening plate is arranged at the corner of a groove in a front longitudinal beam rear portion along the direction of a long axis of the front longitudinal beam rear portion, the front portion rear strengthening plate comprises a bottom plate, and two side plates extending out toward the two sides along the bottom plate, and a support plate extends out of one side plate along the direction of a long axis of the side plate. Due to the body-in-while front longitudinal beam strengthening structure, the situation of bending and failure of a front longitudinal beam is improved. The body-in-while front longitudinal beam strengthening structure not only can achieve the functions needed by normal use of a vehicle, but also can effectively reduce the bending and failure degree of the front longitudinal beam when head-on collision happens, is favorable for promoting the collision performance of the whole vehicle and lightening the harm to passengers in the vehicle, and meanwhile is simple in structure, easy to manufacture and low in cost and has very high social benefit and economical value.
Description
Technical field
The utility model belongs to the auto parts and components field, is specifically related to a kind of body-in-white front longitudinal beam and strengthens structure.
Background technology
In manned vehicle high speed head-on crash process, front stringpiece of vehicle body is important power transmission and energy absorbing component, and front side member body and inner brace panel thereof are the important structure parts that affects power transmission and energy absorption ability.When collision occured, front side member was subject to the impulsive force generation crumple distortion from the front portion, also impulsive force was transmitted backward along himself structure simultaneously.According to the lifting power transmission of common employing and the method for energy absorption ability, generally can be in front side member internal placement brace panel structure.
Former front side member forms the girder construction of remaining silent by inside and outside two sheet metal component make-ups welding, one in front and one in back two brace panels have only been arranged in the front side member front portion, do not strengthen structure at the longeron rear portion, in the high speed head-on crash, the inefficacy that twists easily in the structure turning point of this thin walled beam structure is very disadvantageous for occupant safety and car load collision performance.
Summary of the invention
The purpose of this utility model will provide a kind of exactly can improve front side member buckling failure phenomenon, simple in structure, and anufacturability body-in-white front longitudinal beam good and with low cost is strengthened structure.
For achieving the above object, the designed body-in-white front longitudinal beam of the utility model is strengthened structure, comprise brace panel behind the front brace panel in the front portion that is arranged in the cavity that front side member is anterior and front side member outside plate fastening forms and the front portion, its special character is: also be provided with the rear portion brace panel, described rear portion brace panel is arranged on corner in the front side member rear groove along the long axis direction at front side member rear portion; Brace panel comprises the first base plate behind the described front portion, up extends two the first side plates to both sides along the first base plate, and one of them first side plate extends support plate along its long axis direction.
As preferred version, described rear portion brace panel comprises the second base plate, and described the second base plate extends upward two the second side plates toward both sides, and protuberance is up swelled along its long axis direction in described the second base plate middle part.
Further, offer fixed orifice with the end at described front side member rear portion overlap joint on described the first base plate; The end of described support plate offers the mounting hole with the dynamic assembly suspension overlap joint.
Further, the material that brace panel adopts behind the described front portion is D340DP, and the thickness of described material is 1.6mm.
The utility model has the advantage of: this reinforcement structure can be improved the situation of front side member buckling failure, this structure can not only satisfy outside the needed function of the normal use of vehicle, when head-on crash occurs, can also effectively alleviate the degree of front side member buckling failure, be conducive to promote the car load collision performance, alleviate the suffered injury of occupant on the car, simultaneously simple in structure, be easy to manufacturing and with low cost, have very high social benefit and economic value.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, the high speed head-on crash when occuring in certain motorcar body front side member agent structure, and two point of transition places are that front side member assembly point of transition n easily produces torsional failure in diagram.
Body-in-white front longitudinal beam is as shown in Figure 2 strengthened structure, comprise be arranged on front side member anterior 4 and front side member outside plate 1 fasten before anterior in the cavity that forms brace panel 2 and anterior after brace panel 6, also be provided with rear portion brace panel 8, rear portion brace panel 8 is arranged on corner in 7 grooves of front side member rear portion along the long axis direction at front side member rear portion 7; Brace panel 6 comprises the first base plate 61 after anterior, up extends two the first side plates 62 to both sides along the first base plate 61, and one of them first side plate 62 extends support plate 3 along its long axis direction; Rear portion brace panel 8 comprises that the second base plate 81, the second base plates 81 extend upward two the second side plate 82, the second base plates 81 middle parts and up swell protuberance 83 along its long axis direction toward both sides; Offer the fixed orifice 610 with the end at front side member rear portion 7 overlap joint on the first base plate 61; The end of support plate 3 offers the mounting hole 30 with the dynamic assembly suspension overlap joint.The material that brace panel 6 adopts after anterior is D340DP, and the thickness of material is 1.6mm.
As shown in Figure 3, brace panel 9 structures are very little behind the front portion, prior art Central Plains, the booster action that plays is limited, as shown in Figure 4, anterior rear brace panel 6 front ends of the utility model front side member and dynamic assembly suspension overlap joint, rear end and front side member rear portion 7 overlap joints are positioned at again the top of attachment point 5 before the engine front bracket simultaneously, and are also beneficial to improving before the engine front bracket local stiffness of attachment point 5.
