The invention discloses a high-voltage interlocking structure, a high-voltage controller and a new energy automobile. The high-voltage interlocking structure comprises an MCU unit, a photoelectric switch unit and a comparison unit. The photoelectric switch unit comprises a photoelectric sensor and a partition plate; the signal output end of the MCU unit sends a detection signal to the input end of the comparison unit through the photoelectric switch unit, the output end of the comparison unit is connected with the signal input end of the MCU unit, and the photoelectric switch unit is used for controlling on-off of the detection signal according to whether light emitted by the photoelectric sensor is blocked by the partition plate or not. The comparison unit is used for outputting different voltage signals according to on-off of the detection signals, and the MCU unit can compare the detection signals with the voltage signals and determine the connection state of the first connecting piece and the second connecting piece according to the comparison result. According to the high-voltage interlocking structure, the function of an interlocking switch is achieved through photoelectric signals, and the high-voltage interlocking structure has the advantages of being high in vibration resistance, low in assembly tolerance requirement, simple in structure and the like.
