When used in an all-terrain vehicle, a common type of seat usually includes a seat baseplate and a soft cushion. The soft cushion is arranged on the seat baseplate. The seat baseplate includes a backrest and base. In the process of machining, the backrest and base are machined separately, and then the backrest and base are assembled into one body. The machining procedure of this production mode is tedious and inefficient.
Therefore, how to simplify the machining process described above, to improve production efficiency and reduce production cost, is a technical defect which urgently needs to be solved for those skilled in the art.
