Abstract

The invention discloses an automobile longitudinal beam inner plate assembly, which comprises a longitudinal beam inner plate and a reinforcement which is connected to the inner side of the longitudinal beam inner plate through a bolt, and is characterized in that: the reinforcement is a groove-shaped structural member which is integrally formed; the side face of the reinforcement is provided with a first lightening hole and a second lightening hole; and the side face of the reinforcement between the first lightening hole and the second lightening hole is also provided with a first boss and a second boss. The assembly is rational in structural design and difficult for bending deformation, and can fully absorb collision energy, so that acceleration peak in a collision process of a vehicle is reduced, and the integrity of the automobile and the safety of passengers are protected.

Description

A kind of automobile longitudinal girder inner panel assembly
Technical field
The present invention relates to a kind of body structure of automobile, be specifically related to a kind of longeron inner panel assembly that is used for frontal crash of vehicles.
Background technology
Vehicle safety performance is the important indicator of modern automobile quality, and how when automobile crashes, protecting occupant's damage safe, that reduce automobile to greatest extent is the target that each auto vendor makes great efforts.When automobile bumped, automobile longitudinal girder was as topmost absorption cell, and its energy-absorbing effect directly influences crew module's safety.
Longeron design-calculated aim is: longitudinal beam front section energy-absorbing as much as possible, and back segment is indeformable as much as possible; So anterior rigidity should be lower than rear portion rigidity, this is in order both to guarantee that vehicle acceleration peak value in collision process is more little good more, to guarantee crew module's integraty again.
Existing longeron is divided into two types usually: a kind of is the laser assembly solder girder work; The laser welding position of this structure is engine mounting bracket front end longeron place; Longitudinal beam front section and back segment adopt the material of different-thickness attribute; When head-on crash, let the longitudinal beam front section energy-absorbing be out of shape more easily, the indeformable assurance spatial integrity of back segment shape, but its cost is somewhat expensive.Another kind is non-laser assembly solder girder work, and its cost is lower, but longeron bends distortion easily in head-on crash, well energy-absorbing; The longeron of this structure comprises longeron outside plate assembly and longeron inner panel assembly; Longeron inner panel assembly is formed (like Fig. 1, Fig. 2, shown in Figure 3) by longeron inner panel and reinforcement; Wherein reinforcement (as shown in Figure 2) is made up of a, b two parts, between ab, has tens millimeters apart, its insufficient strength when collision; The bending distortion takes place in longeron part between ab easily, thereby influences the abundant energy-absorbing of longitudinal beam front section.
Summary of the invention
The purpose of this invention is to provide a kind of automobile longitudinal girder inner panel assembly, its reasonable in design is difficult for taking place the bending distortion, and ability is the absorbing impact energy fully, thereby reduces the acceleration peak value of vehicle in collision process, the integraty of protection automobile and occupant's safety.
A kind of automobile longitudinal girder inner panel assembly of the present invention; Comprise the longeron inner panel and pass through bolted connection at the inboard reinforcement of longeron inner panel; It is characterized in that: said reinforcement is the bathtub construction part of a global formation; On the side of reinforcement, be provided with first lightening hole and second lightening hole, on the reinforcement side between first lightening hole and second lightening hole, also be provided with first boss and second boss.
Further, the upper surface of said reinforcement and lower surface are equipped with some guide channels.
Further, the front portion, side of said longeron inner panel is provided with six roots of sensation longitudinal rib at least, is positioned at the length of the length of longitudinal rib foremost less than other longitudinal rib.
The present invention designs reinforcement as a whole and increases by two boss at the middle part, side; Portion increases longitudinal rib quantity in face of the longeron inboard side, and the intensity of reinforcement, longeron inner panel is increased, the abundant conquassation of this structure guiding longitudinal beam front section when collision; Avoided longitudinal beam front section energy-absorbing district serious bending to occur; Make the abundant energy-absorbing of longitudinal beam front section, reduced acceleration peak value, improved the safety performance of vehicle in collision.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1, Fig. 2, shown in Figure 3; Existing longeron inner panel assembly comprises and existing reinforcement 3 and existing longeron inner panel 4, and existing reinforcement 3 passes through bolted connection in existing longeron inner panel 4 inboards; Existing longeron inner panel 4 upper ends connect wheel cover, and the lower end connects the adapter plate that suspends.Existing reinforcement 3 is made up of a and b two parts, when they are connected longeron inner panel inboard, tens mm distance L is arranged between two parts; When bumping; Bend distortion this local generation easily, thereby influence the energy-absorbing of longitudinal beam front section, be provided with four existing longitudinal ribs (41,42,43,44) and four existing some muscle (45,46,47,48) in the front portion, side of existing longeron inner panel 4; Its insufficient strength also can influence the energy-absorbing of longitudinal beam front section.
Like Fig. 4, Fig. 5, Fig. 6, Fig. 7, automobile longitudinal girder inner panel assembly of the present invention shown in Figure 8; Comprise longeron inner panel 1 and pass through the reinforcement 2 of bolted connection in longeron inner panel 1 inboard; Reinforcement 2 is the bathtub construction part of a global formation; On the side of reinforcement 2, be provided with first lightening hole 21 and second lightening hole 24,, be used to gain in strength on the reinforcement side between first lightening hole 21 and second lightening hole 24, also being provided with first boss 22 and second boss 23; Be provided with four guide channels (25,26,27,28) in the upper surface of reinforcement 2, also be provided with three guide channels (29,30,31) in the lower surface of reinforcement 2.Longeron inner panel 1 upper end connects wheel cover; The lower end connects the adapter plate that suspends; Front portion, side at longeron inner panel 1 is provided with six roots of sensation longitudinal rib, is positioned at the length of the length of longitudinal rib 11 foremost less than other longitudinal rib (12,13,14,15,16), and the length of other longitudinal rib is identical.
