Joint structure and method for assembling a joint structure

A method for assembling a joint structure, the joint structure including a first latching member and a second latching member, the first latching member including a first main body, a headend extending from the first main body, and a first convex portion extending from the first main body, the second latching member including a second main body, a second convex portion extending from the second main body, and a third convex portion extending from the second main body, the method for assembling the joint structure comprising:

• calculating a first installed position of the first latching member and a second installed position of the second latching member, wherein the first installed position is located on a surface of a first entity, and the second installed position is located on a surface of a second entity;
• installing the first latching member in the first installed position and installing the second latching member in the second installed position;
• calculating a hanging position and a center position on a second surface of the first entity according to a centroid position of the first entity, wherein a first included angle is defined by a line connecting the hanging position and the centroid position and a line connecting the center position and the centroid position;
• hanging the first entity at the hanging position;
• and
• assembling the first latching member and the second latching member by abutting the headend on a second inner side of the second convex portion to make the first entity rotate about the headend by a second included angle.
