As shown in fig. 18 and 19, the triggering function of the gear signal is realized by the magnet 205 embedded in the gear shift lever assembly 2 and the non-contact angle sensor 402 welded on the PCB board 401, and when the gear shift lever assembly 2 rotates, the non-contact angle sensor 402 can recognize the position signal and further convert the position signal into the gear signal to be sent.

As shown in fig. 11, 13 and 16-17, the present invention realizes the replacement of sliding friction into rolling friction by the flexible connection of the gear shift block 5 with the lower bracket 104 in the horizontal, vertical and vertical directions on one hand, and the replacement of the sliding mode of the slide rod 202 on the gear shift block 5 by the rolling of the roller 203 on the gear shift block 5 on the other hand, so as to greatly reduce the shift operating noise.

According to the invention, the gear shifting feeling and the gear shifting action sound are independently controlled and matched, the gear shifting action sound is realized by independently controlling the buffer design of the front limit position limit, the rear limit position limit and the rebound position limit in the figure 16, and the gear shifting feeling and the gear triggering are independently controlled by sliding the sliding rod 202 on the curved surface of the gear block 5 in the figure 15.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
