[0029] Embodiment:
[0030] A bracket structure for an automotive power system, including a U-shaped bracket plate 10, and the bracket plate 10 includes a first fixing surface 120, a first extension surface 130, a second extension surface 140, a mounting surface 110, and a second fixing surface 150 that are connected in sequence;
[0031] A first bending angle 20 is formed at the connection between the first fixing surface 120 and the first extension surface 130, a second bending angle 30 is formed at the connection between the first extension surface 130 and the second extension surface 140, a third bending angle 40 is formed at the connection between the second extension surface 140 and the mounting surface 110, and a fourth bending angle 50 is formed at the connection between the mounting surface 110 and the second fixing surface 150;
[0032] Reinforcing rib members 60 are provided on both the first extension surface 130 and the fourth bending angle 50, and reinforcing convex members 70 are provided on both the second bending angle 30 and the third bending angle 40.
[0033] It should be noted that the bracket structure also includes a plurality of mounting holes, and these mounting holes are evenly distributed on the first fixing surface 120, the first extension surface 130, the second extension surface 140, the mounting surface 110, and the second fixing surface 150. These mounting holes are used to fix the bracket at the corresponding position of the vehicle to ensure its stability and reliability. Among them, the bracket plate 10 is made of high-strength steel, and if necessary, a special heat treatment process can also be carried out. This treatment not only improves the strength and toughness of the material, but also enhances its corrosion resistance, ensuring that the bracket maintains a good working state during long-term use
[0034] In practical applications, the bracket structure can be installed in the engine compartment of an automobile to fix and support important components such as the engine and transmission. Its unique U-shaped design gives the bracket high stability and load-bearing capacity, meeting the high requirements of modern automobiles for the stability of the power system. Among them, the reinforcing rib members 60 and reinforcing convex hull members 70 provided on the bracket plate 10 can effectively improve the strength of the installation location. The setting of the fillet 80 can increase the bending strength here. The combined setting of the reinforcing rib members 60, the reinforcing convex hull members 70, and the fillet 80 not only solves the problem of insufficient strength of the part, but also solves the problems of part fracture and deformation caused by poor local strength of the part, thereby effectively improving the overall stiffness of the part and reducing the deformation of the part.
[0035] Combined with the attached drawings of the specification Figures 1-4 As shown, the reinforcing rib member 60 includes a first reinforcing rib 610 and a second reinforcing rib 620. The first reinforcing rib 610 is arranged inside the first extension surface 130, and the second reinforcing rib 620 is arranged inside the fourth bending angle 50. Both ends of the first reinforcing rib 610 are recessed inside the first bending angle 20 and the second bending angle 30 respectively. The recessed depth and width of the first reinforcing rib 610 are 1.5 mm and 7 mm respectively. The second reinforcing rib 620 protrudes from the top surface of the fourth bending angle 50, and the protruding height and width of the second reinforcing rib 620 are 2.5 mm and 12 mm respectively.
[0036] It is explained that the setting of the first reinforcing convex hull 710 and the second reinforcing convex hull 720 not only increases the local strength, but also disperses the stress concentration through their shapes, thereby further improving the load-bearing capacity and durability of the bracket.
[0037] Specifically, in terms of design, each surface and bending angle of the bracket structure have been precisely calculated and optimized according to the actual assembly requirements to ensure that the bracket can remain stable and will not undergo excessive deformation when bearing the weights and working loads of components such as the engine and transmission. In addition, the surface of the bracket structure can also be painted or plated according to actual needs to improve its corrosion resistance and ensure good appearance and performance in the harsh automobile use environment.
[0038] Combined with the attached drawings of the specification Figures 1-4As shown, the reinforcing convex hull member 70 includes a first reinforcing convex hull 710, a second reinforcing convex hull 720, and a third reinforcing convex hull 730. The first reinforcing convex hull 710 is disposed inside the second bending angle 30. The second reinforcing convex hull 720 and the third reinforcing convex hull 730 are arranged in a row inside the fourth bending angle 50. The first reinforcing convex hull 710 is recessed inside the second bending angle 30, and the recessed depth and width of the first reinforcing convex hull 710 are 3.5 mm and 8 mm respectively. The second reinforcing convex hull 720 and the third reinforcing convex hull 730 are recessed in a row inside the fourth bending angle 50, and the recessed depth and width of the second reinforcing convex hull 720 and the third reinforcing convex hull 730 are 4 mm and 10 mm respectively. A fillet 80 is further provided at the connection between the mounting surface 110 and the second fixing surface 150. The fillet 80 protrudes inside the fourth bending angle 50, and the covering corner of the fillet 80 is R5.
[0039] It should be noted that the U-shaped support plate 10 forms each bending angle through an accurate bending process to ensure the accuracy of the angle and the stability of the structure. The reinforcing rib member 60 and the reinforcing convex hull member 70 are set by welding or integral molding to ensure their firm combination with the support plate 10.
[0040] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
