Detailed implementation manners

[0023] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification.

[0024] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present application. Therefore, they do not have technical essential meanings. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present application. At the same time, the terms such as "front", "rear", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear description and are not used to limit the implementation scope of the present application. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present application can be implemented.

[0025] It should be noted that in the prior art, the longitudinal beam sill beam connection bracket is usually of a box-shaped structure and is formed by integral stamping. The box-shaped structure has a certain depth, and the stamping forming is difficult. During the stamping process, the drawing depth of the sheet metal is required to ensure the box depth. And because it is an integral forming structure, during use, stress concentration is likely to occur, the stiffness and strength of the connection bracket are relatively limited, there is a risk of cracking, and during the painting processing production process, this integral forming structure is not convenient for processing and is also prone to damage during processing.

[0026] Please refer to Figures 1 to 4 , the present application exemplarily provides a longitudinal beam sill beam connection bracket, including:

[0027] The bracket body, the bracket body includes a bottom plate 7, a first side plate 1, a second side plate 2, a third side plate 3 and a fourth side plate 4. The first side plate 1, the second side plate 2, the third side plate 3 and the fourth side plate 4 are formed by folding on the bottom plate 7 and enclose the periphery of the bottom plate 7. The first side plate 1 and the second side plate 2 are arranged opposite to each other, and the third side plate 3 and the fourth side plate 4 are arranged opposite to each other. Both sides of the first side plate 1 have a first folding structure 5, and a first welding part is arranged on the first folding structure 5. The first side plate 1 is connected to the third side plate 3 and the fourth side plate 4 through the first folding structure 5. Both sides of the second side plate 2 have a second folding structure 6, and a second welding part is arranged on the second folding structure 6. The second side plate 2 is connected to the third side plate 3 and the fourth side plate 4 through the second folding structure 6.

[0028] In the longitudinal beam threshold beam connection bracket provided by the present application, first, the first side plate 1, the second side plate 2, the third side plate 3 and the fourth side plate 4 are formed by folding on the bottom plate 7 and enclose the periphery of the bottom plate 7 to form a box-shaped structure. The first folding structure 5 of the first side plate 1 is connected to the third side plate 3 and the fourth side plate 4 by welding, and the second folding structure 6 of the second side plate 2 is also connected to the third side plate 3 and the fourth side plate 4 by welding to form a self-welding structure of the bracket body. The first folding structure 5, the second folding structure 6 overlap and are welded to the third side plate 3 and the third side plate 3, and then it can be formed. There is no need to adopt the stamping forming method, which reduces the forming difficulty of the connection bracket, and at the same time prevents the risk of cracking caused by the stamping drawing depth, and improves the overall structural strength.

[0029] In this embodiment, the first welding part and the second welding part form a self-welding surface on the first folding structure 5 and the second folding structure 6. The box-shaped body of the connection bracket is fixed and formed by spot welding, forming a self-welded part with a box-shaped structure, which ensures the integrity of the connection bracket. By overlapping and welding the first folding structure 5, the second folding structure 6 with the third side plate 3 and the third side plate 3, it is equivalent to increasing the thickness at the corners of the box-shaped structure formed by the connection bracket, strengthening the structural support ability, increasing the load-bearing weight of the connection bracket, reducing stress concentration, and effectively improving the overall stiffness and strength of the connection bracket.

[0030] In this embodiment, a positioning through hole 8 for processing positioning is opened on the bottom plate 7. The circumferential direction of the positioning through hole 8 has a reinforcing convex structure. Specifically, in the process of painting processing and production, the connection bracket is assembled on the positioning pin of the painting fixture through the positioning through hole 8, which is convenient for processing and production. The circumferential reinforcing convex structure of the positioning through hole 8 is formed by flanging the circumferential direction of the positioning through hole 8, enhancing the structural strength of the positioning through hole 8 and avoiding deformation of the bottom plate 7 caused by collision when the positioning through hole 8 is penetrated on the positioning pin.

[0031] In this embodiment, the longitudinal beam sill beam connection bracket further includes: a reinforcing plate 10 disposed on the bracket body. The reinforcing plate 10 can enhance the structural stability of the bottom plate 7. During the painting process, the bottom plate 7 is the installation surface for the painting fixture. By supporting the bottom plate 7 through the reinforcing plate 10, the structural strength of the bottom plate 7 is improved. Specifically, the bottom of the reinforcing plate 10 is in close contact with the surface of the bottom plate 7. Connection portions 13 are provided around the reinforcing plate 10. The reinforcing plate 10 is connected to the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 through the connection portions 13. Specifically, the connection portions 13 are formed by folding on the reinforcing plate 10. By spot welding between the connection portions 13 and the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, and spot welding between the bottom of the reinforcing plate and the bottom plate 7, the reinforcing plate 10 is connected to the bracket body.

[0032] In some embodiments, through holes 19 are formed in the reinforcing plate 10. The through holes 19 correspond to the positioning through holes 8. The through holes 19 pass through the reinforcing protrusion structure. The aperture of the through holes 19 is larger than that of the positioning through holes 8. During connection, the reinforcing plate 10 will not collide with the reinforcing protrusion structure 14, which is convenient for assembling the reinforcing plate 10 on the bracket body.

[0033] In this embodiment, a first notch 15 is formed between the first side plate 1 and the third side plate 3 and the fourth side plate 4, and a second notch 16 is formed between the second side plate 2 and the third side plate 3 and the fourth side plate 4. Specifically, the height of the first folding structure 5 is less than that of the first side plate 1, and the height of the second folding structure 6 is less than that of the second side plate 2. There is a gap between the first folding structure 5 and the bottom plate 7, forming the first notch 15. There is a gap between the second folding structure and the bottom plate 7, forming the second notch 16. In the existing box-shaped structure formed by stamping, cracks are likely to occur at the four corners. Through the first notch 15 and the second notch 16, stress concentration can be reduced, and sheet metal accumulation can also be avoided.

[0034] In some embodiments, first reinforcing ribs 11 are provided at the connection between the first side plate 1, the second side plate 2 and the bottom plate 7. Flanging structures 9 are provided on the side of the first side plate 1 and the second side plate 2 opposite to the bottom plate 7. Second reinforcing ribs 12 are provided at the connection between the flanging structures 9 and the first side plate 1 and the second side plate 2. The overall structural strength of the bracket body is enhanced through the first reinforcing ribs 11 and the second reinforcing ribs 12.

[0035] In this embodiment, the side of the third side plate 3 and the fourth side plate 4 close to the vehicle body is the first welding surface 17. The third side plate 3 and the fourth side plate 4 are connected to the vehicle body by welding. The side of the flanging structure 9 close to the vehicle body is the second welding surface 18. The first side plate 1 and the second side plate 2 are connected to the vehicle body by welding. The first welding surface 17 and the second welding surface 18 are welded to the vehicle body by spot welding and CO2 shielded welding to ensure the overall strength of the connection bracket after being installed on the vehicle body.

[0036] In another embodiment, as Figure 2 and Figure 3 shown, the present application also provides an automobile, including the longitudinal beam sill beam connection bracket described above.

[0037] In summary, in the longitudinal beam sill beam connection bracket provided by the present application, first, the first side plate 1, the second side plate 2, the third side plate 3 and the fourth side plate 4 are folded and formed on the bottom plate 7 and enclose the periphery of the bottom plate 7 to form a box-shaped structure. The first folding structure 5 of the first side plate 1 is connected to the third side plate 3 and the fourth side plate 4 by welding. The second folding structure 6 of the second side plate 2 is also connected to the third side plate 3 and the fourth side plate 4 by welding to form a self-welding structure of the bracket body. The first folding structure 5, the second folding structure 6 and the third side plate 3, the third side plate 3 overlap and are welded together to be formed, without the need to adopt a stamping forming method, which reduces the forming difficulty of the connection bracket, and at the same time prevents the risk of cracking caused by the stamping drawing depth, and improves the overall structural strength.
