Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame cross beams, in particular to a vehicle frame cross beam reinforcement structure. Background Art

[0002] Crossbeams occupy an important position in the structural technology of vehicle frame assemblies. With the development of the automotive industry, especially the increasing load-bearing capacity of heavy-duty vehicles, the requirements for the toughness and strength of crossbeams are also getting higher and higher.

[0003] Existing crossbeams are mostly stamped from high-strength steel plates. They are not only used to ensure the torsional rigidity of the frame and withstand longitudinal loads, but also to support the main components of the car. However, the crossbeam itself has poor resistance to torsional deformation and is prone to torsional deformation during operation, so a reinforcement structure is needed. Utility Model Content

[0004] Based on the above description, the present invention provides a frame crossbeam reinforcement structure to solve the shortcomings of the existing crossbeam itself, such as poor anti-torsion deformation ability and easy deformation.

[0005] The utility model is realized through the following technical solutions:

[0006] A frame crossbeam reinforcement structure includes a crossbeam body, the middle part of the crossbeam body is bent into an arch structure, a notch is provided on the side wall surface of the crossbeam body at the center, a support plate is provided at the notch, the top plate and bottom plate of the support plate are respectively tightly fitted and fixedly connected to the inner wall of the crossbeam body, and a plurality of connecting parts are respectively provided on the outer side wall of the crossbeam body and arranged on both sides of the notch.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the cross-sections of the beam body, support plate and connecting member are all arranged in an inverted "X" shape, wherein the bottom end of the connecting member is attached to and welded to the side wall of the beam body, and a through hole is opened at the center of the raised part of the connecting member.

[0009] Furthermore, the top plate end of the support plate is bent upward to form a folded edge, which is attached to the inner side wall at the center of the beam body and welded fixed, and the bottom plate of the support plate extends horizontally toward the inside of the beam and is welded fixed to the inner bottom surface of the beam body.

[0010] Furthermore, the side of the support plate facing the first notch is an inclined surface, and the center of the inclined surface is recessed toward the interior of the beam body and forms a trapezoidal structure with the top plate, the bottom plate and the inner wall of the beam body.

[0011] Furthermore, a reinforcing rib is provided at the bend of the beam body. The reinforcing rib is arranged in an L shape and has a flange at the end of the vertical section. The flange and the horizontal section are both attached to the bottom surface of the beam body and welded to it.

[0012] Furthermore, positioning holes of the same size as the through holes are provided on the horizontal sections of the crossbeam body and the reinforcing ribs.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] 1. This application uses support plates and reinforcing ribs to effectively increase the anti-torsional deformation effect of the bends in the middle and at both ends of the beam, reduce the risk of cracking of the beam, and effectively improve the overall structural strength of the beam. Moreover, the plate structure used above is light and can also avoid excessive mass that affects the normal use of the beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0023] Combine Figure 1-5 As shown, a frame crossbeam reinforcement structure includes a crossbeam body 1, which is made of high-strength stamping, and the middle part of the crossbeam body 1 bulges upward to form an arch structure, and a notch 11 is opened on the side wall at the center of the arch part. A support plate 2 is installed inside the notch 11, and the top plate and bottom plate of the support plate 2 are tightly fitted with the inner wall of the crossbeam body 1 respectively.

[0024] The support plate 2 and the beam body 1 are both arranged in an inverted "X" shape structure, and the top plate end of the support plate 2 is bent upward to form a folded edge 21, and the folded edge 21 is fitted with the inner wall of the end of the beam body 1 away from the notch 11, and the bottom plate of the support plate 2 is horizontally fitted on the inner bottom surface of the beam body 1, and the folded edge 21 and the bottom plate of the support plate 2 are fixedly connected to the inner wall of the beam body 1 by welding.

[0025] In addition, the outward side of the support plate 2 is also set as an inclined surface. In order to further improve the anti-bending effect of the inclined surface, the middle part of the inclined surface should be concave inward, thereby increasing its rigidity without adding additional material.

[0026] Combining the above structure and Figure 1 , Attachment Figure 2 As shown, it can be known that the entire support plate 2 is installed inside the beam body 1, and the support plate 2 as a whole and the inner wall of the beam body 1 can form a trapezoidal structure.

[0027] The stability of a trapezoid lies somewhere between a triangle and a parallelogram. This stability is related to the length relationship between the upper and lower bases. As the upper base approaches zero, the entire trapezoid approaches a triangle, and the trapezoid becomes increasingly stable, or more stable. However, as the upper base approaches the lower base, the trapezoid approaches a parallelogram, and the trapezoid becomes more easily deformed, thus becoming less stable.

[0028] Therefore, in this embodiment, the width of the top plate of the support plate 2 should be shortened as much as possible so that it can obtain higher stability.

[0029] A connecting piece 3 is also provided on the outer wall of the beam body 1. The connecting piece 3 is also arranged in an X-shaped structure and is arranged in number and is respectively arranged on both sides of the notch 11. It is mainly used to assist in the installation of sensors and other automotive parts. The two sides of the bottom end of the connecting piece 3 are attached to the outer wall of the beam body 1 and welded and fixed. A through hole 31 is also opened at the center of the raised part of the connecting piece 3.

[0030] In this embodiment, the beam body 1 is an arched structure, so the bends at both ends also need to be equipped with components to increase strength, that is, reinforcing ribs 4 are provided at the bends. The reinforcing ribs 4 are L-shaped metal plates, and the top of the reinforcing ribs 4 is provided with flanges 41. The flanges 41 extend in the horizontal direction and are welded and fixed to the bottom surface of the end of the beam body 1. The horizontal section of the reinforcing ribs 4 is welded and fixed to the bottom surface of the middle part, so that the bent part of the beam body 1 is covered and protected by the right-angle part.

[0031] Positioning holes 5 of the same size as the through holes 31 are provided on the side walls of the crossbeam body 1 and the horizontal sections of the reinforcing ribs 4, and threaded structures are provided on the hole walls of the positioning holes 5 and the through holes 31 for auxiliary fixation with the longitudinal beams or automobile parts.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
