1. A non-pneumatic tire, comprising:
a tread layer which is annular and has a maximum outer diameter of the non-pneumatic tire and is adapted to be in contact with a ground;
a spoke layer comprising an inner cylinder and a plurality of spoke assemblies, wherein the spoke assemblies extend in a radial direction of the non-pneumatic tire and are arranged around an axial core of the non-pneumatic tire; an end of each of the spoke assemblies is connected to the inner cylinder, and another end of each of the spoke assemblies is connected to the tread layer, wherein each of the spoke assemblies comprises:
a straight spoke;
a bending spoke comprising a first segment and a second segment, wherein the first segment and the second segment are not connected in a straight line; and
a connecting rib having a first end and a second end opposite to the first end, wherein the first end is connected to the straight spoke, and the second end is connected to the bending spoke;
wherein when the non-pneumatic tire bears a weight and is squeezed, the spoke assemblies do not get in contact with one another;
wherein the first segment extends along a straight line, and the second segment extends along another straight line;
wherein an angle, which is not equal to 180 degrees, is formed between the first segment and the second segment of the bending spoke of each of the spoke assemblies; the angle is greater than 90 degrees and is smaller than 180 degrees; and
wherein the second end of the connecting rib of each of the spoke assemblies is correspondingly connected to a junction of the first segment and the second segment of the bending spoke.
