That is, the features with "first", "second" can explicitly or implicitly include one or more features. In addition, unless otherwise stated, the meaning of "multiple" is two or more.

[0022] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] As Figures 1-3 shown, the front subframe of the utility model embodiment, including crossbeam assembly 1 and two groups of longitudinal beam assembly 2. Two groups of longitudinal beam assembly 2 correspond to be welded and fixed at the both ends of crossbeam assembly 1 to form front subframe.

[0024] Crossbeam assembly 1 includes crossbeam upper sheet 11 and crossbeam lower sheet 12, and crossbeam lower sheet 12 is correspondingly fixedly connected to the bottom of crossbeam upper sheet 11. By welding crossbeam assembly 1 into crossbeam upper sheet 11 and crossbeam lower sheet 12, the size of a single sheet body is small in the processing process, the stamping deformation is small, the original material length-width model can be flexibly selected for layout stamping, the material utilization rate is improved, and the processing difficulty is reduced, and the qualified rate of finished products is improved.

[0025] Two groups of longitudinal beam assembly 2 are correspondingly fixedly connected to the both ends of crossbeam assembly 1, and longitudinal beam assembly 2 includes longitudinal beam upper sheet 21 and longitudinal beam lower sheet 22, and longitudinal beam lower sheet 22 is correspondingly fixedly connected to the bottom of longitudinal beam upper sheet 21. Similarly, by welding longitudinal beam assembly 2 into longitudinal beam upper sheet 21 and longitudinal beam lower sheet 22, the size of a single sheet body is small in the processing process, the stamping deformation is small, the original material length-width model can be flexibly selected for layout stamping, the material utilization rate is improved, and the processing difficulty is reduced, and the qualified rate of finished products is improved.

[0026] Based on the above structure, by setting crossbeam assembly 1 and longitudinal beam assembly 2 into a split structure, the material utilization rate and the qualified rate of finished products can be improved.

[0027] As Figure 2As shown, in some embodiments, the front subframe includes a suspension bracket 3 and a first sleeve 4. The suspension bracket 3 is provided at the bottom of the crossbeam lower piece 12. The upper end of the first sleeve 4 is mounted in the through hole of the crossbeam upper piece 11. The lower end of the first sleeve 4 is mounted in the through hole of the crossbeam lower piece 12. The suspension bracket 3 is mounted on the lower end of the first sleeve 4. The provision of the suspension bracket 3 allows for the installation of vehicle components, thereby improving the installation capability of the front subframe.

The second sleeve 23 is used to install the steering gear.

[0029] like Figure 2 As shown, in some embodiments, the longitudinal beam assembly 2 includes a front bracket upper piece 24 and a front bracket lower piece 25. The front bracket lower piece 25 is fixedly connected to the bottom of the front bracket upper piece 24, which is fixedly connected to the front end of the longitudinal beam upper piece 21. The front bracket lower piece 25 is fixedly connected to the front end of the longitudinal beam lower piece 22. By welding the front bracket upper piece 24 and the front bracket lower piece 25 together to form the front bracket, the size of each piece is reduced during processing, and stamping deformation is minimized. The length and width of the raw materials can be flexibly selected for layout and stamping, thereby improving material utilization, reducing processing difficulty, and improving the qualified rate of the finished product.
