1. A flat plate member, comprising:
a plurality of sidewall regions; and
a connection region connected between adjacent sidewall regions, the connection region being formed with a plurality of V-shaped grooves arranged at intervals in an arrangement direction of adjacent sidewall regions on a surface facing a first side, and the connection region being adapted to be bent so that the plurality of sidewall regions form a box body,
wherein the plurality of V-shaped grooves extend along a direction of intersection lines between the sidewall regions and the connection region, and an included angle of the V-shaped grooves is set according to a slotting influence parameter, and the slotting influence parameter comprises at least one of a bending angle of the connection region, a material of the connection region, and a number of the V-shaped grooves, and
wherein the connection region comprises a first end and a second end respectively connected to two adjacent sidewall regions, and the plurality of V-shaped grooves are located between the first end and the second end,
the first end is formed with a first bending portion facing the first side, and the first bending portion is adapted to form a first bending position between the connection region and one of the sidewall regions,
the second end is formed with a second bending portion facing the first side, and the second bending portion is adapted to form a second bending position between the connection region and the other one of the sidewall regions; wherein the first bending portion and the second bending portion are both formed as recesses.
