The anti-collision beam assembly in the embodiment of the utility model refers to a safety device which is positioned at the front and rear area parts of the vehicle and used for absorbing and buffering the external impact force in the collision working condition so as to protect the front and rear parts of the vehicle, and the structure and the function of the safety device are similar to those of a beam body structure, thus the anti-collision beam assembly is called as an anti-collision beam assembly; the energy absorption box is a box-shaped structure which is positioned in the vehicle and is used for connecting and fixing an anti-collision beam and a frame, and is a main buffer component of the anti-collision beam assembly; the aluminum alloy extrusion molding process refers to a structure with a specific cross-section shape obtained by hot melting and extrusion of an aluminum rod, so that the requirements of structural components on different strength and different rigidities are met; the anti-collision beams are transversely distributed along the width direction of the vehicle, and the longitudinal beams are longitudinally distributed along the length direction of the vehicle.

The anti-collision beams, the energy-absorbing boxes and the front and rear longitudinal beams of more and more vehicle types adopt aluminum alloy extrusion parts with better energy-absorbing performance, and the anti-collision beams, the energy-absorbing boxes and the front and rear longitudinal beams in the related art all adopt integral equal-thickness structures, so that the reduction of materials is particularly important as far as possible under the requirement of meeting structural strength, in the vehicle body design, only local structures or certain areas are required to be structurally reinforced, however, the effect of structural reinforcement is realized by adopting the integral thickening of certain surface or cavity in the related art, and the structural reinforcement mode can play the role of reinforcing the structure, but more weight redundancy and additional cost are often generated.

In order to solve the technical problems that the prior anti-collision beam assembly is easy to generate more weight redundancy and extra cost when in structural reinforcement, so that the anti-collision beam assembly cannot give consideration to structural strength and weight.

As shown in fig. 1 to 5, a first aspect of the present utility model provides an impact beam assembly 100, the impact beam assembly 100 comprising an impact beam 10, an energy-absorbing box 20 and a frame (including a longitudinal beam 30), the impact beam 10 being mounted on the inner side of a sheet metal of a vehicle body, the energy-absorbing box 20 being disposed on the side of the impact beam 10 facing away from the sheet metal of the vehicle body, the energy-absorbing box 20 being connected between the impact beam 10 and the frame, wherein the energy-absorbing box 20 and/or the frame comprises a shell (including a first rectangular shell 21 and a second rectangular shell 31) and a stiffener (including a cross-shaped stiffener 22 and a linear stiffener 32) disposed in the shell, the shell being provided with a connection portion 101 connected with the stiffener, the cross-section of the connection portion 101 being disposed as an arch-shaped profile curved toward the inside of the shell.

In this embodiment, the anti-collision beam assembly 100 provided in the embodiment of the present utility model reduces the phenomena that the connection portion 101 of the shell is easy to deform and damage in the collision process by setting the connection portion 101 of the shell to be in an arch-shaped profile, and meanwhile, the embodiment of the present utility model can reduce the influence on the overall structure and the overall weight of the shell because the overall thickness and the overall weight of the shell are not increased.

Specifically, the working principle of the arch profile is similar to that of an arch bridge, the reinforcing rib is connected to the middle part of the arch profile, and when the reinforcing rib applies acting force to the middle part of the arch profile, the arch profile can transfer the acting force of the reinforcing rib to two sides of the arch profile, so that the purpose of dispersing the acting force of the reinforcing rib is achieved.

Further, since the arch profile is provided to be curved toward the inside of the case, even if the external force applied to the arch profile exceeds the plastic deformation capability of the arch profile, the outer concave portion of the arch profile can provide a deformation space for the arch profile, reducing the occurrence of breakage of the arch profile after the external force is applied.

Still further, the shell and the reinforcing ribs are integrally formed by extrusion through aluminum alloy, so that the shell, the reinforcing ribs and the connecting structure of the shell and the reinforcing ribs have higher structural strength, and the phenomenon that the energy absorption box 20 and the frame are damaged and broken in the using process is reduced. In addition, the shell and the reinforcing ribs are integrally formed through aluminum alloy extrusion, so that the manufacturing difficulty of the shell and the reinforcing ribs can be reduced, and the production efficiency of the energy absorption box 20 and the frame can be improved.

As will be appreciated by those skilled in the art, the main deformation energy absorbing area of the energy absorbing box 20 and the frame during the crash test is the connection portion 101 between the shell and the reinforcing rib, and based on this consideration, the embodiment of the present utility model proposes to provide an arch profile at the connection portion 101 to improve the energy absorbing efficiency and reduce the deformation, and in the same crash test, compared with the energy absorbing box 20 adopting an equal thickness in the related art, the thickness of the energy absorbing box 20 according to the embodiment of the present utility model can be reduced by more than 10% compared with the thickness of the energy absorbing box 20 according to the related art.

It should be noted that the embodiment of the present utility model is not limited to the structure of the housing, because the structure of the housing includes various types, such as a cross section of the housing includes a rectangular, diamond, trapezoid, polygonal or arc structure, and the structure belongs to the protection scope of the housing of the present utility model. Also, the structure of the reinforcing rib is not limited in the embodiment of the present utility model, because the structure of the reinforcing rib includes various types, for example, the reinforcing rib includes a straight structure, a cross structure, or a cross structure, and the like, and the structure belongs to the protection scope of the reinforcing rib of the present utility model.

In addition, the embodiment of the present utility model proposes that the energy-absorbing box 20 is connected between the anti-collision beam 10 and the vehicle frame, the vehicle frame includes a longitudinal beam 30 and a transverse beam of the vehicle frame, both the longitudinal beam 30 and the transverse beam belong to the protection scope of the vehicle frame of the present utility model, and for convenience of explanation, the embodiment of the present utility model is explained below with the energy-absorbing box 20 connected between the anti-collision beam 10 and the longitudinal beam 30 of the vehicle frame.

As shown in fig. 1-5, in some embodiments, the housing comprises a rectangular housing and the stiffener comprises a cross-shaped stiffener 22 or at least one in-line stiffener 32 disposed within the rectangular housing.

In this embodiment, the rectangular housing includes a cube and a cuboid, the crash box 20 located at the head position may be set to be a cube and a cross-shaped reinforcing rib 22, and the frame located at the tail position may be set to be a cuboid and a straight-shaped reinforcing rib 32, so as to meet the requirements of different positions of the vehicle body on different collision strengths, and on the basis of meeting the basic strength requirements, the waste of materials is reduced as much as possible.

Preferred embodiments of the crash box 20 and the specific structure of the vehicle frame are described below.

As shown in fig. 2 and 3, in some embodiments, the crash box 20 includes a first rectangular shell 21 and a cross-shaped reinforcing rib 22 provided in the first rectangular shell 21, four side walls of the first rectangular shell 21 are provided with four connection portions 101 connected to the cross-shaped reinforcing rib 22, and the four connection portions 101 are each bent toward the inside of the shell.

In this embodiment, taking the case that the impact beam assembly 100 is disposed at the front portion of the vehicle body as an example, because the front portion of the vehicle body needs to meet severe working conditions such as SOB (front small paranoid collision) and MPDB (movable deformable barrier collision), the energy-absorbing box 20 of the impact beam assembly 100 is a main energy-absorbing buffer component, the requirement on the structural strength of the energy-absorbing box 20 is higher, and by disposing the cross-shaped reinforcing ribs 22 inside the energy-absorbing box 20, the structural strength of the energy-absorbing box 20 can be improved, and the risk of damage to the energy-absorbing box 20 in the collision working condition can be reduced.

Specifically, the cross-shaped reinforcing ribs 22 can increase the bearing range of the energy-absorbing box 20, so that the four walls of the energy-absorbing box 20 can achieve the effect of structural reinforcement, and the phenomenon that the energy-absorbing box 20 is locally damaged under the collision working condition of the vehicle is reduced.

As shown in fig. 2 and 3, in some embodiments, the crash box 20 is provided in a letter-in-field structure composed of a first rectangular shell 21 and a cross-shaped reinforcing rib 22, four ends of the cross-shaped reinforcing rib 22 are connected to four inner walls of the first rectangular shell 21, and four outer walls of the first rectangular shell 21 are formed with four grooves corresponding to the four ends of the cross-shaped reinforcing rib 22.

In this embodiment, the crash boxes 20 are arranged in a shape like a Chinese character 'tian', so that the crash boxes 20 form a symmetrical structure, thereby improving the stress balance of the crash boxes 20 and reducing the occurrence of local stress concentration of the crash boxes 20 in a collision scene of a vehicle.

Further, since the arched profile is configured to bend toward the inside of the shell, the outer wall of the energy-absorbing box 20 forms a groove corresponding to the arched profile, so that when the external force borne by the arched profile exceeds the plastic deformation capability of the arched profile, the groove of the outer wall of the energy-absorbing box 20 can also provide a deformation space for the arched profile, and the phenomenon that the arched profile is deformed and raised after the external force is borne is reduced.

As shown in fig. 4 and 5, in some embodiments, the frame includes a side member 30 connected to the crash box 20, the side member 30 includes a second rectangular shell 31 and at least one in-line stiffener 32 disposed within the second rectangular shell 31, and two opposite side walls of the second rectangular shell 31 are provided with two connection portions 101 connected to each in-line stiffener 32.

In this embodiment, the longitudinal beam 30 of the anti-collision beam assembly 100 does not need to bear too large bearing force in light collision, but needs to consider the working condition of MPDB (movable deformable barrier collision), and meanwhile needs to consider the space adaptability of the longitudinal beam 30, so the embodiment of the utility model proposes to provide the in-line reinforcing rib 32 inside the longitudinal beam 30 to meet the structural strength requirement and the space adaptability of the longitudinal beam 30.

Specifically, the longitudinal beam 30 located at the vehicle head position may be provided with two in-line reinforcing ribs 32, and the two in-line reinforcing ribs 32 are distributed at intervals inside the longitudinal beam 30, so as to improve the structural strength of the longitudinal beam 30 and improve the energy absorption and buffering performance of the longitudinal beam 30.

Further, since the requirements of the vehicle tail on the collision of the collision avoidance beam assembly 100 are relatively less stringent, only one in-line reinforcing rib 32 can be arranged in the longitudinal beam 30 and the energy absorber box 20 of the collision avoidance beam assembly 100 at the vehicle tail, and the miniaturization requirements of the collision avoidance beam assembly 100 at the vehicle tail are realized on the basis of meeting the collision requirements of the collision avoidance beam assembly 100 at the vehicle tail.

As shown in fig. 4 and 5, in some embodiments, the stringers 30 are provided in a daily-or mesh-shaped structure composed of a second rectangular shell 31 and straight reinforcing ribs 32, and two outer walls of the second rectangular shell 31 are formed with two grooves corresponding to each straight reinforcing rib 32.

In the present embodiment, taking the girder 30 of the japanese-character-shaped structure or the mesh-shaped structure as an example, if the thickness of the girder 30 is 2.6mm in the related art, the embodiment of the present utility model can reduce the thickness of the girder 30 to 2.2mm by setting the connection portion 101 of the girder 30 to an arch-shaped profile, and reduce the overall weight of the girder 30 by about 10%, and the technical effects of the both can be basically equivalent through CAE analysis crash test.

Further, since the arched profile is configured to bend toward the inside of the shell, the outer wall of the energy-absorbing box 20 forms a groove corresponding to the arched profile, so that when the external force borne by the arched profile exceeds the plastic deformation capability of the arched profile, the groove of the outer wall of the energy-absorbing box 20 can also provide a deformation space for the arched profile, and the phenomenon that the arched profile is deformed and raised after the external force is borne is reduced.

As shown in fig. 1 to 5, in some embodiments, the connection part 101 of the housing is bent toward the inside of the housing, the inner wall of the connection part 101 forms an arch profile on the inner wall of the housing, and the outer wall of the connection part 101 forms a groove on the outer wall of the housing, and the arch profile is integrally formed with the groove.

In this embodiment, the arch profile and the groove are integrally formed, that is, in the process of manufacturing the arch profile, the arch profile and the groove can be simultaneously formed by extruding the arch profile into the shell at the position of the connecting portion 101, the arch profile can disperse the acting force of the reinforcing rib, and the groove can provide a buffer deformation space for the arch profile, so that the breaking damage phenomenon of the arch profile after bearing the acting force of the reinforcing rib is reduced.

In some embodiments, the impact beam assembly 100 further includes a stiffener embedded in the groove, and an outer wall of the stiffener is disposed flush with an outer wall of the shell.

In this embodiment, if the whole structure of the anti-collision beam assembly 100 is made of aluminum alloy, there are technical problems of high manufacturing cost and heavy structure.

Specifically, the reinforcement can set up in the recess of casing through welded mode, and the reinforcement includes the reinforcing plate, and the reinforcing plate welds to the outer wall of recess to make reinforcement and casing enclose into the hollow tank, not only improved the structural strength of casing, also little to the influence of the whole weight of casing.

As shown in fig. 1-5, in some embodiments, the housing is provided in a rectangular configuration, the inner walls of the corners 102 of the housing are provided as thickened inner walls that are extruded into the interior of the housing, and/or the outer walls of the corners 102 are provided as arcuate chamfer 103 or cut chamfer 103.

In this embodiment, taking the energy-absorbing box 20 in a shape of a Chinese character 'tian' as an example, if the thickness of the energy-absorbing box 20 in the related art is 2.6mm, in the embodiment of the present utility model, by arranging the arc chamfer 103 or the cutting chamfer 103 on the outer wall of the corner 102, the thickness of the energy-absorbing box 20 can be reduced to 2.2mm, and the overall weight of the energy-absorbing box 20 is reduced by about 10%, and by using CAE analysis crash test, the technical effects of the two can be basically equivalent.

Likewise, the scheme of the arc chamfer 103 or the cutting chamfer 103 can be applied to the cross beam 30 and the Chinese character 'ri' shaped longitudinal beam 30, and on the premise of realizing the same collision performance, the weight of the energy-absorbing box 20 can be reduced by more than 10% and the material cost of parts can be reduced by more than 10% by arranging the arc chamfer 103 or the cutting chamfer 103 on the outer wall of the corner 102.
