The invention belongs to a triple-folding type vehicle-mounted tail board which comprises two tail frame boxes below the rear end of an automobile carriage. The lifting arm is characterized in that a groove is formed in the lifting arm, the included angle alpha between the bottom face of the groove and the inclined face of the right end is 100-120 degrees, the included angle alpha between the bottom face of the groove and the inclined face of the left end is alpha 1, and alpha 1 is 130-150 degrees; the upper surface of the right end of the lifting arm is hinged with holes of two left rings in the three-fold hinge through a connecting ring shaft I; two first connecting lugs in the three-folding hinge are fixedly connected with a groove formed in the left side of a three-folding platform in the lifting platform; two grooves in the right side of the three-folding platform are connected with two grooves in the left side of the two-folding platform through two two-folding hinges; the two grooves in the right side of the two-fold platform are fixedly connected through a first-fold hinge base in a first-fold hinge. Through the design of the lifting arm and the folding platform, the size is small after folding, the strength is high, and the weight and size range of objects borne by the tail plate is enlarged.

    本发明属于一种三折叠式车载尾板,包括汽车车厢后端下面的两个尾架盒;其特征在于升降臂上面制成凹槽,凹槽底面与右端的斜面夹角为α,α=100°‑120°,凹槽底面与左端的斜面夹角为α1,α1=130°‑150°;升降臂右端上面用连接环轴一与三折铰链中的两个左环的孔铰连接;三折铰链中的两个连接耳一与升降平台中的三折平台左侧设的凹槽固定连接;三折平台右侧两个凹槽与二折平台左侧的连个凹槽用两个二折铰链连接;二折平台右侧的两个凹槽用一折铰链中的一折铰链座一固定连接。该发明通过对升降臂和折叠平台的设计,折叠后体积小,强度大,尾板承载物品重量和尺寸范围扩大。
