The invention provides a longitudinal beam structure and a vehicle. The longitudinal beam structure comprises a central passage longitudinal beam, a front longitudinal beam and a connection section, wherein the connection section is connected between the central passage longitudinal beam and the front longitudinal beam; the front longitudinal beam comprises a front longitudinal beam front section, a front longitudinal beam rear section and a front longitudinal beam middle section; the front longitudinal beam middle section is arranged between the front longitudinal beam front section and the front longitudinal beam rear section, and is connected with the central passage longitudinal beam through the connection section; and the material strength of the front longitudinal beam middle section is greater than that of the front longitudinal beam front section and that of the front longitudinal beam rear section. Through the adoption of the technical scheme disclosed by the invention, the problem of longitudinal beam structure damage due to the situation that stress cannot be effectively transferred by the longitudinal beam structure during a collision of the vehicle in the prior art can be solved effectively.
Description
Technical field
The present invention relates to technical field of vehicle, in particular to a kind of longitudinal beam structure and vehicle.
Background technology
The longitudinal beam structure of existing vehicle is substantially symmetrically arranged, is therefore described from the one side of longitudinal beam structure and also can reflect entirely
Longitudinal beam structure.The description below is only described from the left side of longitudinal beam structure.
As shown in figure 1, the left longeron of vehicle includes left rear longitudinal beam 1 and left front girder.Left front girder is by left front girder back segment 2 and a left side
Front longitudinal leading portion 3 is welded.This left longitudinal beam structure extends through the tailstock always by Herba Plantaginis, is " the middle stream whetstone of whole vehicle body
Post ".On the one hand it serve the effect of supporting vehicle body, on the other hand when vehicle occurs longitudinal impact it is also possible to disperse impact energy
Amount and the deformation resisting vehicle body.
Vehicle central passage longeron is welded by the left longitudinal beam front section of centre gangway and centre gangway left longeron back segment, and this structure is by front
Coaming plate extends to rear ground prelaminar part.Existing structure left-right longeron and centre gangway left-right longeron are single two structures,
Therebetween it is not attached.When vehicle occurs central collision and offset collision, collision transmission power is individually along longeron and centre gangway
Longeron is delivered to after vehicle body, and due to not being attached between longeron and centre gangway longeron, power can not effectively disperse to transmit,
Front panel may be led to invade, and driving cabin is excessive, ftracture in floor, Seat-fixed point displacement is big, equal to driver and passenger safety
Cannot ensure well, reduce security performance.
Fig. 2 shows the technical scheme solving the above problems in prior art.In this technical scheme, left front girder back segment 2, a left side
Front longitudinal leading portion 3 constitutes one section of complete left front girder, welds between the middle part of this left front girder and the left longeron of centre gangway 4
One connector 5.So, when colliding, the stress that left front girder is subject to will be transferred to a centre gangway left side from connector 5
Longeron 4 is so that stress can disperse to transmit.
But, in actual applications, the part being connected with connector 5 of left front girder understands the premature deterioration because of stress concentration,
Lead to stress can not be transferred on the left longeron of centre gangway 4 according to as anticipation.
