Description

Technical Field

[0001] The utility model relates to the technical field of Yuanbao beams, in particular to a reinforced Yuanbao beam for automobiles. Background Art

[0002] The Yuanbao beam, also known as the subframe, refers to the bracket that supports the front and rear axles and suspension. It is a device that connects the axles and suspension to the "main frame" through it. After installation, it can block vibration and noise and reduce the noise that directly enters the car.

[0003] Currently, the commonly used Yuanbao beam structures are mostly welded structures, that is, multiple parts are assembled and then welded to form a complete Yuanbao beam. However, this type of directly spliced ​​Yuanbao beam itself does not have a pre-fixed structure, which makes the processing efficiency relatively low. At the same time, there is stress concentration in the beam body under bending and torsion conditions, and the joints on both sides are prone to cracking and fracture failures. Therefore, a Yuanbao beam with a simple welded structure and a reliable structure is needed. Utility Model Content

[0004] Based on the above description, the utility model provides a reinforced Yuanbao beam for automobiles to solve the shortcomings of the existing welded Yuanbao beam structure, such as low processing efficiency, stress concentration in the beam body, and easy cracking and fracture failures.

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

[0009] Furthermore, bolt holes are respectively opened at four corners of the surface of the fixing plate and are locked and fixed to the frame by bolts.

[0010] Furthermore, the reinforcement comprises a rectangular metal plate, baffles are provided on both sides of the metal plate, the centers of the two baffles are bent outward, the top ends of the baffles extend toward the center of the metal plate to form an installation space with a flat cross-section, the socket is connected to the installation space, and a gap is left between the top ends of the two baffles to form an opening.

[0011] Furthermore, the top surface of the reinforcement is provided with an elliptical through hole, and a plurality of the through holes are arranged symmetrically about the center of the reinforcement.

[0012] Furthermore, the connecting member is provided with a triangular reinforcing rib, which is arranged between the second section and the third section and is fixed by bolts.

[0013] Furthermore, a plurality of welding holes are longitudinally opened on the outer side wall of the reinforcement, each of the welding holes is filled with seam welding metal, and the seam welding metal is welded and fixed to the first section of the outer side wall of the connector.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] The present application is based on the improvement of the existing Yuanbao beam structure, and the middle of the reinforcement member located in the middle is changed to a cylindrical shape, so that it can cover the ends of the two connecting members. Compared with the original Yuanbao beam, the splicing effect is more convenient and stable, and the overlapping part between the connecting member and the reinforcement member is more, and the two are fixed by subsequent welding, and the connection is tighter;

[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] 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 belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combination Figure 1-4 As shown, a reinforced Yuanbao beam for automobiles comprises:

[0025] The connecting member 1 is a metal strip with a flat cross section, two of which are provided, and one end of which is fixedly connected to the vehicle body by a bolt structure;

[0026] The reinforcing member 4 is rectangular and hollow inside, and has insertion holes for fixing the connecting member 1 on the end faces at both ends, so as to be combined with the connecting member 1 to form a Yuanbao beam;

[0027] The fixing plate 3 is arranged at the end of the connecting member 1 and is used to cooperate with the bolt structure to connect with the automobile body.

[0028] Specifically, the connector 1 is divided into three sections, namely, a first section 11, a second section 12 and a third section 13, wherein the first section 11 is arranged horizontally, and its end is inserted into the socket of the end surface of the reinforcing rib 4, and the other end of the first section 11 is connected to the end of the second section 12; the third section 13 is connected to the end of the second section 12, and the second section 12 is tilted and continuously bent in a direction away from the reinforcing rib 4. Figure 2 and Figure 3 As shown; the third section 13 can be arranged horizontally or tilted according to actual needs so as to be used with a variety of different car models.

[0029] On this basis, the connector 1 is further provided with a reinforcing rib, which is a triangular plate and is arranged between the second section 12 and the third section 13. Figure 2 As shown, both sides are fixed to the connecting member 1 body by bolts respectively, so when the end of the connecting member 1 is subjected to a large force, the reinforcing ribs can protect it and enhance the anti-cracking and anti-fracture effects.

[0030] In addition, the fixing plate 3 should be set on the top surface of the third section 13, so the fixing plate 3 is welded and fixed to the end of the connecting piece 1, and bolt holes 31 are also opened at the four corners of the top surface of the fixing plate 3. The bolt holes 31 penetrate downward and are connected with the bolt holes 31 of the reinforcing ribs. The fixing plate 3 and the reinforcing ribs are locked and fixed with the same set of bolts.

[0031] The reinforcement 2 includes a metal plate and a baffle, see Figure 4 As shown, the metal plate is the main part, and the baffles on both sides extend in an arc shape toward the center and leave a gap, forming a semi-enclosed structure, so that the end of the first section 11 on the connecting member 1 can be easily inserted into the interior of the reinforcement 2, and then the baffles are pressed to move toward the center and tightly clamp the connecting member 1.

[0032] The top surface of the reinforcement 2 is provided with an elliptical through hole 21, and there are four through holes 21 arranged symmetrically with respect to the center of the reinforcement 2. The side wall of the reinforcement 2 is provided with four welding holes 22, which are also symmetrically arranged with respect to the center of the reinforcement 2. The through holes 21 and the welding holes 22 are filled with seam welding metal. Therefore, in the subsequent welding process, the seam welding metal can be combined with the connecting piece 1 and the reinforcement 2 by ultrasonic welding, so that they are fixed to each other to form a whole, thereby strengthening the connection effect between the connecting piece 1 and the reinforcement 2. In this welding method, since the welding material is located in the hole, there will be no structures such as burrs and burrs. After the welding is completed, the next process can be directly started, which speeds up the production efficiency of the Yuanbao beam.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model 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 solution recorded 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 solution from the technical solution of the embodiments of the utility model.
