[0002] At present, the global automobile production and ownership are increasing. Major automobile companies are trying their best to improve the economic efficiency of automobile parts production under the condition of ensuring automobile safety and performance. In the past, due to the styling characteristics of beam assembly parts, the production stability and product qualification rate have been in an unsatisfactory state for a long time, and the defective quality is mostly dark cracks, which are difficult to identify in actual production. In bench tests, this defect will evolve from dark cracks to cracks, resulting in the overall safety of the large assembly not meeting the requirements. The styling characteristics of the beam assembly pose great challenges to the subsequent product process and production, and are part of the standards for measuring the experience of production process planners and production departments. Therefore, the design and optimization technology of the crossbeam assembly styling structure of cars is the top priority for the subsequent development of similar parts. Utility Model Content

[0003] The purpose of the utility model is to provide a new energy vehicle crossbeam, which has the advantage of ensuring that the performance indexes of the original parts are maintained while making some changes to the local shape structure of the existing crossbeam, thereby improving the productivity, pass rate and stability of the product in the actual production process, reducing the risk of cracking in the crossbeam assembly bench test, extending the service life of the vehicle, ensuring driving safety in harsh environment sections, making the product quality stable and reliable, and improving the stability of the production process for assembly parts.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a new energy vehicle crossbeam, including a crossbeam assembly, the crossbeam assembly includes a crossbeam body, side panels 1 and 2 are fixedly installed on both sides of the crossbeam body, a front wall panel and a rear wall panel are arranged on the top of the crossbeam body and located between the side panels 1 and 2, the top and one side of the side panel 1 are respectively provided with flange 1 and flange 2, a side of the side panel 2 is provided with flange 3, an inner recessed groove 1 is provided between the flange 1 and the flange 2, and an inner recessed groove 2 is provided between the flange 3 and the side panel 2, reinforcing ribs are fixedly installed between the side panel 1 and the flange 1, the side panel 1 and the flange 2, the side panel 2 and the flange 3 and the side panel 1 and the crossbeam body, a welding nut is welded on the top of the crossbeam body, the welding nut includes a nut body, a welding boss is provided at the bottom of the nut body, and inclined surfaces are formed on both sides of the welding boss.

[0005] The above technical solution is adopted: in the use of the new energy vehicle crossbeam, an assembly component will be formed by the crossbeam assembly, the front wall plate and the rear wall plate. The crossbeam body will avoid the stacking and cracking of materials between the flange one and the flange two, and between the flange three and the side panel two through the setting of the inner recessed groove one and the inner recessed groove two. The difference is that the boundaries of the existing above-mentioned parts are too long, which makes the material flow space small during the molding process of the crossbeam product, resulting in the stacking and cracking of materials at the above-mentioned joints. By shortening the boundaries of the joints and reducing the excess materials at the joints, the occurrence of defects such as cracking and hidden cracks is improved, and the difficulty of on-site debugging is reduced. The quality of the crossbeam is guaranteed to be stable, the manufacturing is stable, the service life of the vehicle is extended, and cracking during the bench test is prevented. The reinforcing ribs installed in the corner areas between the side panel one and the flange one, the side panel one and the flange two, the side panel two and the flange three and the side panel one and the crossbeam body are helpful to adjust the flange one and the flange with the reinforcing ribs as the center. Second, the accuracy of the flange third, the existing flange accuracy of the beam assembly parts is difficult to adjust in actual production, and the adjustment time is long, the workload is large, and the difficulty is high. By adding reinforcing ribs in the corner area, the reinforcing ribs are easy to adjust and have a small amount of modification compared to the corner area, which greatly improves the timeliness and convenience of actual debugging. This change improves the stability of the product accuracy, saves a lot of costs in actual debugging, and at the same time improves the product fillet rigidity, further improving the strength of the beam assembly. At the same time, in the installation and welding of the welding nut and the beam body, the welding boss is used in conjunction with the nut body for welding, and the two sides of the welding boss are affected by the inclined surface to have a gradually upward inclined surface, which is different from the existing downward inclined surface. When the nut body is pressed down, the welding boss is deformed and contacts the bottom of the nut body. At the same time, the bottom of the welding boss contacts the beam body, which helps to improve the welding firmness of the nut body.

[0006] The utility model is further configured such that the crossbeam body, the first side panel and the second side panel are all integrally formed.

[0007] The above technical solution is adopted: the firmness between the crossbeam body, the side panel one and the side panel two is ensured through one-piece molding.

[0008] The utility model is further configured such that the side panel 1, the flange 1 and the flange 2 are integrally formed, and the side panel 2 and the flange 3 are integrally formed.

[0009] The above technical solution is adopted: the firmness between the side panel one, the flange one and the flange two is ensured through the one-piece molding, and the firmness between the side panel two and the flange three is also ensured.

[0010] The utility model is further configured that there is a distance difference of mm between the sunken groove 1 and the flange 1 and flange 2.

[0011] By adopting the above technical solution, the arrangement of the sunken groove 1 facilitates avoiding the stacking and cracking of the materials between the flange 1 and the flange 2.

[0012] The utility model is further configured such that there is a distance difference of mm between the second inner recessed groove and the third flange and the second side plate.

[0013] By adopting the above technical solution, the second sunken groove is provided to facilitate avoiding the stacking and cracking of the materials between the flange three and the side plate two.

[0014] The utility model is further configured such that corner areas for installing matching reinforcing ribs are formed between the side panel 1 and flange 1, the side panel 1 and flange 2, the side panel 2 and flange 3, and the side panel 1 and the crossbeam body.

[0015] The above technical solution is adopted: mutually mounted bending arcs are formed through the corner areas.

[0016] The utility model is further configured that the top of the crossbeam body is provided with an embedded groove for matching with the installation of the welding nut.

[0017] The above technical solution is adopted: the welding nut is installed through the embedded groove to prevent the welding nut from protruding to the top of the beam body.

[0018] The utility model is further configured such that the nut body and the welding bosses are integrally formed, the number of the welding bosses is four, and the welding bosses are arranged at equal intervals around the circumference at the bottom of the nut body.

[0019] The above technical solution is adopted: the welding boss is used in conjunction with the nut body for welding.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the use of the cross beam of the new energy vehicle, the cross beam body will avoid the stacking and cracking of the materials between the flange 1 and the flange 2, and between the flange 3 and the side plate 2 through the arrangement of the sunken groove 1 and the sunken groove 2. The difference is that the boundaries of the above parts of the existing products are too long, which makes the material flow space small during the molding process of the cross beam products, resulting in the stacking and cracking of the materials at the above joints. By shortening the boundaries of the joints and reducing the excess materials at the joints, the occurrence of defects such as cracking and dark cracks is improved, and the difficulty of on-site debugging is reduced, so as to ensure the stable quality and stable manufacturing of the cross beam, extend the service life of the vehicle, and prevent cracking during the bench test;

[0022] 2. In the use of the new energy vehicle cross beam of the utility model, the reinforcing ribs are helpful to adjust the accuracy of the first, second and third flanges with the reinforcing ribs as the center. The flange accuracy of the existing cross beam assembly parts is difficult to adjust in actual production, and the adjustment time is long, the workload is large and the difficulty is high. By adding reinforcing ribs in the corner area, the reinforcing ribs are easy to adjust and the modification amount is small compared with the corner area, which greatly improves the timeliness and convenience of actual debugging. This modification improves the stability of the product accuracy, saves a lot of costs in actual debugging, and improves the product fillet rigidity, further improving the strength of the cross beam assembly;

[0023] 3. In the use of the new energy vehicle cross beam of the utility model, in the installation welding of the welding nut and the cross beam body, the welding boss is used in conjunction with the nut body for welding, and the two sides of the welding boss have gradually inclined upward surfaces through the inclined surfaces, which is different from the use of the existing downward inclined surfaces. When the nut body is pressed down, the inclined surface of the welding boss is deformed and contacts with the bottom of the nut body. At the same time, the bottom of the welding boss contacts with the cross beam body, which helps to improve the welding firmness of the nut body. BRIEF DESCRIPTION OF THE DRAWINGS
