Background
The gear hand feeling design that the left (L) of present knob formula outside rear-view mirror switch, right (R) mirror surface were selected has two kinds:
1. in the process that the knob is shifted from an O gear to an L gear or an R gear, the force value hand feeling is suddenly changed when the knob is rotated to an angle position of about 30 degrees, and then the knob is rotated by 15 degrees to reach the L gear or the R gear; when the knob returns to the gear O from the gear L or the gear R, the knob is firstly rotated by 15 degrees, then the force value and the hand feeling are suddenly changed, and then the knob returns to the gear O after going through the rotation angle of 30 degrees. The abrupt change position of the force value hand feeling is at the 2/3 angle boundary line position of the 'O' gear- > 'L' or 'R' gear.
In the design, because the position of the abrupt change point of the hand feeling force value is at the 2/3-degree dividing line position of the 'O' gear- > 'L' or 'R' gear, and when the 'L' or 'R' gear returns to the 'O' gear, the position is at the 1/3-degree dividing line position, when a user operates the knob, two inconsistent hand feeling experiences can be caused when the user turns to the 'L' or 'R' gear and returns from the 'L' or 'R' gear, and particularly, when the user returns to the 'O' gear, the user has a sharp feeling due to small climbing angle (15 degrees) and large gradient.
2. In the process that the knob is shifted from an O gear to an L gear or an R gear, the force value hand feeling is suddenly changed when the knob is rotated to an angle position of about 22.5 degrees, and then the knob is rotated by 22.5 degrees to reach the L gear or the R gear; when the knob returns to the gear O from the gear L or the gear R, the knob is firstly rotated by 22.5 degrees, then the force value and the hand feeling are suddenly changed, and then the knob returns to the gear O after going through the rotation angle of 22.5 degrees. The abrupt change position of the force value hand feeling is on the angle bisector of the 'O' gear- - > 'L' or 'R' gear.
According to the design scheme, the sudden change point of the hand feeling value is arranged at the angle level parting line position of the 'O' -gear > 'L' or 'R' -gear, so that reciprocating hand feeling can be kept consistent when the knob is operated.
