Further preferably, the pad 210 is arranged in a stepped structure, wherein the shaft diameter at both ends of the pad 210 is greater than the shaft diameter in the middle of the pad 210, and when the pad 210 is embedded in the annular protrusion 120, the upper part of the pad 210 is located on the upper surface of the annular protrusion 120, and the lower part of the pad 210 is located on the lower surface of the annular protrusion 120, that is, a structure similar to a "sandwich" shape is formed between the pad 210 and the annular protrusion 120, further improving the connection strength between the housing 100 and the bracket 300.

[0043] More preferably, if Figure 1 and Figure 2As shown, a through groove 310 is opened along the thickness direction of each corner of the bracket 300, which serves as an installation channel for the fixed foot 200, wherein the annular concave surface 320 at the upper end of the through groove 310 forms a positioning fit with the lower end surface of the pad 210 (the end surface of the pad 210 on one side of the lower surface of the annular protrusion 120), so that the housing 100 and the bracket 300 form a seamless connection at their connection position, preventing the automatic shifter assembly from shaking and generating noise at the connection portion between the housing 100 and the bracket 300 when the automatic shifter assembly is installed on the vehicle body, thereby further improving the reliability of the automatic shifter assembly during use.
