Fourth embodiment

Referring to fig. 10 to 11, the autopilot unit 200c of the fourth embodiment is substantially the same as the autopilot unit 200b of the third embodiment, except that the distance between the exposed portion of the column cover 2003 and the motor cover 2001 is increased, the end of the link 10 is provided with a threaded hole 11, and the fixing bracket 100c further includes an adjusting member 40.

The structure of the regulating member 40 is as described in the second embodiment. The adjusting portion 413 is rotated to adjust the distance between the connecting member 30 and the rod portion 411, and further adjust the distance between the abutting member 20 and the connecting member 30, so as to adapt to different distances between the motor casing 2001 and the exposed portion of the steering column casing 2003.

The link 10 is short in length, and cannot hold the retainer 20 and the clamp 50 between them and fixed to the outside of the column cover 2003. The adjusting member 40 is disposed between the connecting rod 10 and the abutting member 20, so that the distance between the abutting member 20 and the connecting member 30 is increased, and the abutting member 20 and the clamping member 50 are clamped and fixed outside the steering column outer shell 2003.

The fixing bracket 100c protects the link 10, the holding member 20, the connecting member 30, the adjusting member 40, and the clamping member 50. The fixing bracket 100c of the first to third embodiments is obtained by removing the adjusting member 40 and/or the clamping member 50, and is adapted to different relative positional relationships formed between the motor housing 2001 and the instrument cover 2005 and the steering column housing 2003, respectively, further improving the versatility of the fixing bracket 100 c.

The fixing support 100 is adjustably mounted on the motor housing 2001 along the second direction through the connecting piece 30, and is respectively clamped outside the connecting rod 10 through the connecting piece 30 and the abutting piece 20, the distance between the connecting piece 30 and the clamping piece 51 in the first direction is adjustable, so that the relative position of the connecting piece 30 and the abutting portion 201 is adjustable, the fixing support 100 is suitable for the motor housing 2001 and the instrument cover 2005 to form different mounting spaces, and the universality of the fixing support 100 is improved.

Although the present application has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present application.
