Automobile auxiliary frame and integrated forming method thereof

The invention discloses an automobile auxiliary frame which comprises a connecting base and an auxiliary frame body, fixing bases are fixedly connected to the left side and the right side of the top of the connecting base, a connecting block is fixedly connected to one side of each fixing base, connecting columns are fixedly connected to the left side and the right side of the bottom of the auxiliary frame body, and guide columns are fixedly connected to the bottom ends of the connecting columns. And the outer surfaces of the guide columns are slidably connected with the interiors of the connecting blocks, and the positions, located above the connecting blocks, of the outer surfaces of the guide columns are sleeved with first springs in an injection mode. According to the automobile auxiliary frame, the force bearing state of the two guide columns can be buffered to a certain extent by means of matching among the guide columns, the connecting blocks, the first spring and a connecting trough, thereby reducing
