The invention discloses a center shaft structure of a centrally-mounted motor. A detection unit comprises a plurality of strain gauges, a rotating assembly and a fixing assembly. The fixed assembly comprises a fixed power supply part, a fixed PCBA and a grating sensor, the fixed power supply part is configured to be powered on from the middle motor, and the fixed power supply part supplies power to the fixed PCBA and the grating sensor; the fixing assembly is fixedly arranged relative to the middle motor. The rotating assembly comprises a rotating power supply part, a rotating PCBA and a grating. The rotating power supply part supplies power to the rotating PCBA. The grating sensor is used for detecting grating signals; the rotating assembly is fixedly arranged relative to the middle shaft; the rotary PCBA is configured to collect the torsional strain of the strain gauge; the rotary power supply component wirelessly supplies power to the fixed power supply component; the fixed PCBA is in wireless communication transmission with the rotary PCBA; and the fixed PCBA is used for signal transmission with the middle motor. According to the middle shaft structure developed by the invention, high integration can be realized in a limited space, the strain and pedaling frequency detection functions are integrated, the number of parts is reduced, and the overall performance is improved.
