The independent inertia measurement unit 10 includes a unit main body 11, a harness connector 12, and two mounting portions 13.
In this embodiment, the unit body 11 has four sides, and the harness connector 12 is located on one side of the unit body 11, and may be integrally formed with the unit body 11 or may be fixedly mounted on the unit body 11. The two mounting portions 13 are symmetrically located on the remaining opposite two side surfaces of the unit main body 11, the mounting portions 13 and the unit main body 11 are integrally formed, threaded holes are formed in the mounting portions 13, and the mounting portions 13 are mounted on the base 30 through screws.
When the installation direction of the independent inertia measurement unit 10 is correct, the fool-proof member 20 is located on one side of the unit main body 11, the fool-proof member 20 and the wire harness connector 12 are located on two opposite sides of the unit main body 11, the height of the fool-proof member 20 is higher than the lower surface of the wire harness connector 12, and the height of the fool-proof member 20 is lower than the upper surface of the unit main body 11, so that the fool-proof member 20 is not interfered with the unit main body 11.
