An automobile seat height adjusting device comprises a driving motor, a shell and a seat fixing and connecting plate, the lower portion of the shell extends to form a worm seat, a worm seat cavity is communicated with a shell cavity, the driving motor is fixed to the shell, the seat fixing and connecting plate is fixed to the shell, and a gear seat cavity is formed in the middle of the seat fixing and connecting plate. A driving wheel receding hole is formed in the center of the left side of the gear seat cavity. The transmission device is characterized in that the transmission device comprises a first-stage transmission mechanism, a second-stage transmission mechanism and a third-stage transmission mechanism, the first-stage transmission mechanism is arranged in a shell cavity and is in transmission connection with a driving motor shaft, the second-stage transmission mechanism is arranged in the shell cavity and is in transmission fit with the first-stage transmission mechanism, and the third-stage transmission mechanism is arranged in a driving wheel receding hole; the right side of the third-level transmission mechanism is matched with the second-level transmission mechanism, and the left side of the third-level transmission mechanism extends out of the driving wheel receding hole. The speed reducer has the advantages of simplifying the structure, reducing the weight, reasonably reducing the size, improving the transmission efficiency, reducing noise and vibration and reducing the fault probability.
