Description
Technical Field
The utility model relates to an electric motor car technical field, especially an electric motor car frame.
Background
The electric bicycle is developed in China from the 80 th of the last century, is continuously perfected, and the structure and the material of the frame of the electric bicycle are improved. Until the low-carbon steel frame is popularized in a large quantity at the beginning of this century, the frame developed and designed by my department meets the requirements of appearance modeling and structural strength and other characteristics through mechanical analysis; at present, for the purposes of cost and safety, the frame products with the structures are not manufactured on the market; the steel is the longest frame material used on the bicycle, and has the main advantages of good processability, easy welding, and the like, so the cost and the price are relatively low. Of course, steel frames also have their insurmountable disadvantages: the weight is too heavy, the maintenance is improper and the rust is easy, the pipe molding is not easy and the metal fatigue is caused. Because the battery or the battery pack is arranged in the vehicle tube, on one hand, the strength of the vehicle tube is possibly reduced, and further various potential safety hazards are caused; on the other hand, the problem that the battery or the battery pack is inconvenient to take and place and the like exists.

In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides an electric vehicle frame, includes the bracing piece, the bracing piece top transversely is provided with the tube head, bracing piece bottom welded mounting has the motor seat, motor seat both sides are provided with motor seat mounting panel, the motor seat is the arc type, be provided with well pipe in the cambered surface of motor seat, motor seat front side fixed mounting has the lug, be provided with the mounting hole on the lug, be fixed with first back vent in the mounting hole, first back vent is fixed with the second back vent through the triangle connecting plate, the top of second back vent is connected with well pipe, the shell is installed outward to bracing piece and motor seat, the shell is laminated mutually with the appearance of bracing piece and motor seat.
Furthermore, the shell comprises a left shell and a right shell, a battery fixing hole is formed in the shell, a battery installation space is formed between the left shell and the right shell, and a battery shell is arranged outside the battery installation control.
Further, the angle between the first rear fork and the second rear fork is 30-60 degrees, and a support plate is arranged between the second rear fork.
Furthermore, the triangular connecting plate fixes the first rear fork and the second rear fork through bolts and nuts.
Furthermore, the motor seat mounting plate is provided with a mounting hole groove.
The utility model has the advantages that: by adopting the right shell and the left shell which are detachably connected, and the battery installation space is arranged between the left shell and the right shell, the strength of the frame can be ensured while the convenience in installing the battery or the battery pack is ensured; through solution welding treatment and aging, the steel plate has the advantages of high rigidity and strength, difficult oxidation at normal temperature and corrosion resistance.
