Claim:
An anti-rollover motorized vehicle comprising a chassis, a front wheel and a rear two wheels assembly, the rear two wheels assembly comprising: a tilting base connected to the chassis through a first supporting structure; a four-bar linkage structure suitable for connecting the chassis with two rear wheels, wherein the four-bar linkage structure comprises: a first linkage pivoted to the tilting base and suitable for being pivoted relative to the tilting base; a second linkage disposed under and parallel to the first linkage, and pivoted to the tilting base, wherein the second linkage is suitable for being pivoted to the tilting base; and a third linkage and a fourth linkage pivoted to two ends of the first and second linkages respectively, and connected to supporting brackets of the two rear wheels, wherein when the chassis is tilted, the tilting base and the first supporting structure are tilted with the chassis, the first linkage and the second linkage are maintained at a constant angle relative to a road surface, and the third linkage and the fourth linkage are tilted with the chassis such that the two rear wheels are suitable for being tilted with the chassis; and two shock absorbers connected to the tilting base and suitable for being connected to the chassis through a second supporting structure, wherein when the chassis is tilted, the two shock absorbers are suitable for being tilted with the chassis, wherein the supporting brackets are not directly connected to the two shock absorbers.
