[0003] The frame is equivalent to the skeleton of an electric vehicle, and the frame strength largely determines the strength of the electric vehicle. During the driving process of the electric vehicle, as the load-bearing carrier of the electric vehicle, the frame not only has to bear the weight of the vehicle body and the human body, but also has to bear the stress generated by bumps and vibrations. At present, the structure of the electric vehicle frame on the market is mostly U-shaped, and the center of gravity of the seat is biased towards the rear side of the U-shaped frame and is only supported by side tubes. After a long time of driving, the frame is prone to deformation and damage, posing a safety hazard. Based on this, the utility model provides an anti-deformation electric vehicle frame. Summary of the Utility Model

A U-shaped tube is fixedly connected to the top of the circular side tube, a second support tube is fixedly connected between the U-shaped tube and the horizontal side of the main beam tube, a first support frame is fixedly connected to the top of the U-shaped tube, a tail tube is fixedly connected to one side of the top of the circular side tube, and a second support frame is fixedly connected to the top of the tail tube.

[0006] Furthermore, the number of the first support tubes is not less than five, and reinforcing ribs are provided at the joints of the side wall of the main beam tube with the circular side tube and the first support tubes.

[0007] Furthermore, a flat fork is provided at one end of the horizontal side of the main beam tube, a shock absorber fixedly connected to the second support frame is provided on the top of the flat fork, and a rear wheel is provided on the flat fork in a matching manner.

[0008] Furthermore, a head tube is provided at one end of the bent side of the main beam tube, a front fork is provided on the head tube in a matching manner, and a front wheel and a handlebar are provided on the front fork in a matching manner.

[0009] Advantages of the present utility model: By providing a plurality of support pipes and reinforcing ribs, the connection between the main beam pipe and the annular side pipe of the present utility model is made more stable.

[0018] Principle of the present utility model:

[0019] Reinforcing ribs 8 are provided at the joints of the side wall of the main beam tube 1 with the annular side tube 6 and the first support tube 7. The multiple support tubes 7 and the reinforcing ribs 8 make the connection between the main beam tube 1 and the annular side tube 6 more stable. The load of the seat is mainly borne by the first support frame 10. The U-shaped tube 9 and the second support tube 11 disperse the load of the seat to the main beam tube 1 and the annular side tube 6, reducing the load borne by the annular side tube 6 and making it less likely to deform. The shock absorber 15 makes the electric vehicle run more smoothly, reduces the stress generated by bumpy vibration, prevents the stress from damaging the vehicle body structure and deforming it, and reduces potential safety hazards.
