[0002] With the development of new energy vehicles, the body structure is gradually developing from the existing steel structure to a steel-aluminum hybrid body. Among them, the front longitudinal beam is an important force-bearing component in the collision process. The front longitudinal beam in the form of aluminum alloy extrusion aluminum is widely used due to its light weight and good collision energy absorption capacity. The main body of the front longitudinal beam adopts an extruded aluminum beam structure, and its front longitudinal beam end plate structure usually also adopts aluminum structural components. The two are connected by MIG welding (molten inert gas shielded welding).

[0003] However, during the current welding process, due to the high heat generated by MIG welding and the fact that the ends of the end plate structure and the front longitudinal beam are usually welded around the perimeter, there is a large internal stress at the weld. After welding, the rear end plate structure is prone to large deformation at the weld under stress pulling and high temperature conditions, resulting in the surface profile of the end plate structure exceeding the standard, which will further lead to installation accuracy errors in the components installed on the end plate structure, reducing the appearance quality of the entire vehicle. Utility Model Content

[0004] The purpose of the utility model is to provide a front longitudinal beam end plate structure, a front end module and a vehicle for an automobile in view of the deficiencies in the existing technology, so as to solve the problem raised in the above background technology that during the welding process, due to the high heat generated by MIG welding and the end of the end plate structure and the front longitudinal beam usually adopting the form of full peripheral welding, there is a large internal stress at the weld, and the rear end plate structure after welding is prone to large deformation of the welding part under stress pulling and high temperature conditions, which causes the surface contour of the end plate structure to exceed the standard, which will further cause installation accuracy errors in the components installed on the end plate structure, thereby reducing the appearance quality of the entire vehicle.

[0033] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a front longitudinal beam end plate structure of an automobile, which is used for welding with the front longitudinal beam 3 of the automobile, and the end plate structure includes:

[0035] End plate body 1;

[0036] Two convex ribs 2 are arranged on both sides of one side of the end plate 1, and at least one groove 10 is arranged on a side of each convex rib 2 away from the end plate body 1;

[0037] When the end plate body 1 is welded to the front longitudinal beam 3 , one end of the front longitudinal beam 3 is inserted between the two convex ribs 2 , and the groove 10 is used to separate the first weld 4 formed between the convex rib 2 and the front longitudinal beam 3 .

[0038] Specifically, in order to solve the problem that, during the welding process, due to the high heat generated by MIG welding and the end of the end plate structure and the front longitudinal beam usually adopts the form of full peripheral welding, there is a large internal stress at the welding point, and the welded rear end plate structure is prone to large deformation of the welding part under stress pulling and high temperature conditions, which causes the surface profile of the end plate structure to exceed the standard, which will further cause the components installed on the end plate structure to have installation accuracy errors and reduce the appearance quality of the whole vehicle. The utility model provides a front longitudinal beam end plate structure of an automobile, wherein two convex ribs 2 are respectively arranged on both sides of one side of the end plate body 1 of the end plate structure, which can greatly improve the structural rigidity of the end plate body 1 and effectively reduce the deformation after welding. One end of the front longitudinal beam 3 is inserted into the two convex ribs 2 The groove 10 is used to separate the first weld 4 formed between the rib 2 and the front longitudinal beam 3. Separating the first weld 4 by the groove 10 avoids long welds and full welds, reduces the internal stress at the welding point, and since the end plate body 1 and the front longitudinal beam 3 are welded by the rib 2, direct welding of one side of the end plate body 1 and one end of the front longitudinal beam 3 is avoided, thereby reducing the deformation of the end plate body 1. At least one groove 10 is provided on the side of each rib 2 away from the end plate body 1. During the welding process, the groove 10 can also absorb the deformation of the rib 2 caused by high temperature, further reducing the deformation of the end plate body 1, improving the installation accuracy of components installed on the end plate structure, and improving the appearance quality of the entire vehicle.

[0039] Preferably, the upper part and the lower part of the end plate body 1 are respectively provided with mounting holes 6, and the mounting holes 6 are used to connect the anti-collision beam to be installed.

[0040] Specifically, the end plate body 1 is used to install the front end frame, wherein the mounting hole 6 is used to install the anti-collision beam.

[0041] Preferably, at least one partition hole 7 is respectively provided at the upper part and the lower part of the end plate body 1;

[0042] At least one second weld 5 is formed between the upper and lower portions of one surface of the end plate body 1 and the upper and lower portions of one end of the front longitudinal beam 3, respectively;

[0043] The at least one partition hole 7 in the upper portion is located between the upper mounting hole 6 and the at least one second weld 5 in the upper portion, and the at least one partition hole 7 in the lower portion is located between the lower mounting hole 6 and the at least one second weld 5 in the lower portion.

[0044] Specifically, the partition hole 7 and the mounting hole 6 are both located between the two convex ribs 2, and the second weld 5 can increase the connection strength between the end plate body 1 and the front longitudinal beam 3. In addition, since one end of the front longitudinal beam 3 is inserted between the two convex ribs 2, the groove 5 is used to separate the first weld 4 formed between the convex rib 2 and the front longitudinal beam 3. Furthermore, the first weld 4 is located on the side wall of the front longitudinal beam 3. The first weld 4 and the second weld 5 are not located on the same vertical plane. In space, the first weld 4 and the second weld 5 form a staggered relationship, which avoids the welding points being located on the same vertical plane and the presence of large internal stress. After welding, the rear end plate structure is prone to large deformation of the welding parts under stress pulling and high temperature conditions, which can effectively ensure the connection strength.

[0045] The number of second welds 5 is the same as that of partition holes 7, and each second weld 5 corresponds to a partition hole 7. The partition holes 7 are in the shape of long strips. During the welding process of the second welds 5, the second welds 5 melt the side of the partition holes 7 away from the mounting holes 6. The deformation caused by the residual stress in the second welds 5 is absorbed by the structure on this side, and the hole edge on the other side of the partition holes 7 is not affected by the deformation, thereby ensuring the surface contour of the end plate body 1 at the mounting hole 6, and further ensuring the installation accuracy of the anti-collision beam.

[0046] Preferably, the end plate body 1 and the front longitudinal beam 3 are both made of aluminum alloy, and the end plate body 1 and the two convex ribs 2 are integrally formed.

[0047] Specifically, the end plate body 1 and the front longitudinal beam 3 made of aluminum alloy are light in weight, have good collision energy absorption capability, and are widely used.

[0048] Preferably, the distance between each rib 2 and a side wall of the front longitudinal beam 3 is between 0.5 and 1 mm.

[0049] Specifically, when the end plate body 1 and the front longitudinal beam 3 are welded and matched, the distance between the rib 2 and the front longitudinal beam 3 is between 0.5 and 1.0 mm, which can not only meet the requirement that one end of the front longitudinal beam 3 is inserted between the two ribs 2, but also meet the gap requirement of the MIG welding connection.

[0050] Preferably, at least one weight-reducing hole 8 is provided on the end plate body 1 between the two ribs 2 .

[0051] The weight-reducing holes 8 are used to reduce the weight of the end plate body 1. There are multiple weight-reducing holes 8, and the multiple weight-reducing holes 8 are staggered with the multiple grooves 10 on each convex rib 2 to ensure that each weight-reducing hole 8 is at the same height as a section of the first weld 4. The side of the weight-reducing hole 8 can absorb the deformation caused by the residual stress in the first weld 4, thereby ensuring the surface contour of both sides of the end plate body 1, ensuring the installation accuracy of the components installed on the end plate structure, and improving the appearance quality of the entire vehicle.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, the utility model provides a front end module of an automobile, comprising:

[0053] Front longitudinal beam 3;

[0054] The front longitudinal beam end plate structure of the automobile is welded to the front longitudinal beam 3;

[0055] Preferably, the front end assembly of the automobile further includes at least one rib plate 9 , and the at least one rib plate 9 is horizontally connected to the inner side of the front longitudinal beam 3 .

[0056] Specifically, the rib plate 9 is used to strengthen the overall strength of the front longitudinal beam 3 .

[0057] Preferably, the number of the ribs 9 is the same as the number of the grooves 5 on each convex rib 2 , and the height of each rib 9 is the same as the height of one groove 5 on each convex rib 2 .

[0058] Specifically, since the height of the rib plate 9 is the same as the height of a groove 5 on each convex rib 2, and therefore, the first weld 4 is cut at the position of each rib plate 9, and since there is no direct welding at this position, the rigidity is relatively large, thereby ensuring that the side wall of the front longitudinal beam 9 at the position of the groove 5 is not easily melted, and effectively reducing the deformation of the rib plate 9, thereby ensuring the strength of the front longitudinal beam 9 and avoiding the overall deformation of the front longitudinal beam 9.

[0059] A car, comprising: a front end module of the car.

[0060] In summary, when the front-end module provided by the present invention is implemented on a car, the two convex ribs 2 can greatly improve the structural rigidity of the end plate body 1, and the deformation after welding can be effectively reduced. The first weld 4 can be separated by the groove 10, and the deformation of the convex rib 2 caused by high temperature can be absorbed, thereby avoiding the welding of long welds and full welds, and reducing the internal stress at the welding point. The second weld 5 can increase the connection strength between the end plate body 1 and the front longitudinal beam 3, and the first weld 4 and the second weld 5 are staggered in space, thereby avoiding the welding points being located on the same vertical plane and having large internal stress. The welded rear end plate structure is prone to large deformation of the welding part under stress pulling and high temperature conditions, and the connection strength can be effectively guaranteed. The second weld 5 is welded through the partition hole 7. During the process, the second weld 5 melts the side of the partition hole 7 away from the mounting hole 6, and the deformation caused by the residual stress in the second weld 5 is absorbed by the structure on this side, and the hole edge on the other side of the partition hole 7 is not affected by the deformation, thereby ensuring the surface contour of the end plate body 1 at the mounting hole 6, and further ensuring the installation accuracy of the anti-collision beam. The first weld 4 is cut off at the position of each rib plate 9. Since there is no direct welding at this position, the rigidity is relatively large, which ensures that the side wall of the front longitudinal beam 9 is not easily melted at the position of the groove 5, effectively reducing the deformation of the rib plate 9, thereby ensuring the strength of the front longitudinal beam 9, avoiding the overall deformation of the front longitudinal beam 9, further reducing the deformation of the end plate body 1, and improving the installation accuracy of the components installed on the end plate structure. Improve the appearance quality of the vehicle.

[0061] The above description of various embodiments of the utility model is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
