Detailed implementation mode

[0014] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 , Figure 2 , Figure 3 shown, the rear cross - fork of the new electric vehicle includes the left arm 1 of the rear cross - fork, the right arm 2 of the rear cross - fork, and a connecting plate 3 for connecting the left arm 1 and the right arm 2 of the rear cross - fork. Through the connecting plate 3, the left arm 1 and the right arm 2 of the rear cross - fork are connected to each other and the stability between them is improved. At the front ends of both the left arm 1 and the right arm 2 of the rear cross - fork, there is an axle connecting plate 4 for connecting the axle of the electric vehicle. A protective ring 5 is provided on the axle connecting plate 4. The protective ring 5 helps to protect the axle installed on the axle connecting plate 4 from bending caused by vehicle collision. And the protective ring 5 is connected to the left arm 1 and the right arm 2 of the rear cross - fork.
