The invention discloses an electric vehicle frame and a disposable integrated forming process of the electric vehicle frame. The electric vehicle frame comprises a front wheel support, a rear wheel support and a saddle support, the front wheel support is connected with the rear wheel support, the saddle support is connected between the front wheel support and the rear wheel support, the front wheel support is provided with a containing cavity, and the rear wheel support is provided with a containing cavity. Due to the fact that the containing cavity is formed in the front wheel support, the storage battery can be installed in the containing cavity of the front wheel support, the whole storage battery is hidden in the front wheel support, and the appearance of a whole vehicle body is more concise. The disposable integrated forming process of the electric vehicle frame comprises the following steps: putting magnesium ingot into a quantitative furnace for smelting, stretching a head tube mold core, a cross bar mold core, a front wheel support mold core, a five-way mold core and a saddle support mold core into a mold for forming a head tube, an upper tube, a lower tube, a five-way hole and a middle tube of the vehicle frame respectively; closing the mold, and preheating the mold; injecting magnesium alloy liquid; and opening the mold, and taking out the formed vehicle frame.

    本发明公开了一种电动车车架及电动车车架的一次性一体式成型工艺,电动车车架包括前轮支架、后轮支架和车座支架,前轮支架与后轮支架连接,车座支架连接在前轮支架与后轮支架之间,前轮支架具有容纳腔,由于容纳腔设在前轮支架上,蓄电池能够安装在前轮支架的容纳腔中,将蓄电池整个隐藏在前轮支架内部,使得整个车体的外观更为简洁,电动车车架的一次性一体式成型工艺,包括以下步骤:将镁锭投入定量炉内熔炼,将头管型芯、横杠型芯、前轮支架型芯、五通型芯和车座支架型芯伸入模具内,分别用于成型车架的头管、上管、下管、五通孔和中管;合模,并将模具预热;注射镁合金液;开模,取出成型后的车架。
