Specific embodiment
Following examples are used for this utility model is described, but are not limited to scope of the present utility model.
Embodiment 1
As shown in figure 1, round sealed formula electromobile frame, including left and right two circular beam 1, front-axle beam 2 and bottom girder 3, left,
It is attached by front-axle beam 2 between the front center of right two circular beam 1, the two ends of described front-axle beam 2 are passed through welding and fixed respectively
Front center in left and right two circular beam 1.The main spar that described bottom girder 3 is made up of front, rear, left and right 4 steel pipe, left,
It is attached by bottom girder 3 between the bottom of right two circular beam 1, four angles of described bottom girder 3 are separately fixed at by welding
The bottom of left and right two circular beam 1.Described front-axle beam 2 is provided with two standpipes 4, and the steel pipe of rear end of described bottom girder 3 is connected with
Two vertical beams 5, two described standpipes 4 are fixed together with two described vertical beams 5 respectively.The steel of the rear end of described bottom girder 3
Two rocking arm mounting ears 6 are additionally provided with pipe, described rocking arm mounting ear 6 is located in the both sides of described vertical beam 5.Left and right two circles
One head tube 7 is also separately installed with the front center of beam 1, described head tube 7 is located at the front end of described front-axle beam 2, two described head tubes 7
Pass through welding respectively to be connected directly between in the front center of left and right two circular beam 1.Between the top of left and right two circular beam 1
Be fixedly connected with back timber 8, in the middle part of the rear end of left and right two circular beam 1 between be fixedly connected with the back rest 9, the left and right of the described back rest 9
