DETAILED DESCRIPTION

[0028] like Figures 1-10 As shown, the utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are the same as Figure 1 The up, down, left, right, front and back directions of the projection relationship itself are consistent. The utility model is an AGV power vehicle with a weighing function, including a frame 11, and a plurality of spoke sensors 13 are arranged on the frame 11. There are four spoke sensors 13, and the spoke sensors 13 are distributed in a Y shape. The spoke sensors 13 are prior art. The spoke sensors belong to a type of weighing sensor. Because their base is like a wheel disc, they are named spoke sensors. They are mainly used in hydraulic press force measurement, testing machines, warehouse weighing, etc. A platform plate 51 is provided on the upper side of the spoke sensor 13, and a universal wheel assembly 15 is provided at one of the diagonals at the bottom of the frame 11, and a steering wheel assembly 14 is provided at the other diagonal at the bottom of the frame 11.
