A multi-stable continuously rotating knob electronic shifter

Abstract

The invention discloses a multi-stable continuously rotatable knob electronic shifter, mainly comprising: a rotating shaft assembly, a knob assembly fixed at the end of the rotating shaft assembly, a magnet installed at the bottom of the rotating shaft assembly, and a 3D gear placed on one side of the magnet. Hall sensor; the outer ring of the rotating shaft assembly is coaxially sleeved with a guide rail, the inner wall of the guide rail is provided with a circle of arc-shaped teeth corresponding to the rotating shaft assembly, and the outer wall of the rotating shaft assembly is embedded with spring positioning beads that cooperate with the arc-shaped teeth. Compared with the traditional multi-stable knob shifter with added solenoid valve and return motor, this scheme has the advantages of simple structure and low cost. Compared with the monostable knob shifter, this scheme reduces one P button, and compared with the three-point monostable knob shifter, the R / D shift only needs to be operated once, which has the advantage of simple operation.

Description

technical field [0001] The invention belongs to the field of automobile gear shifters, in particular to a multi-stable and continuously rotating knob electronic gear shifter. Background technique [0002] According to the classification of the number of knob steady states, the existing knob electronic shifters are divided into two categories: monostable and multistable. The steady state refers to the position where the knob can stay stably after being released, and the unsteady state refers to the position where the knob cannot stop once it is released. [0003] There is an existing monostable knob electronic gear shifter, and the knob is generally used to control the switching of the three gears of R / N / D. According to the total number of steady state and unsteady state, it is further divided into 3-point type (1 steady state, 2 unsteady states) and 5-point type (1 steady state, 4 unsteady states). 3-point knob such as figure 1 As shown, when switching between the R gear ...

AI Technical Summary

Problems solved by technology

[0005] To sum up: monostable knob electronic shifter, 3-point knob operation is cumbersome, and additional P gear button is required

For the multi-stable electronic shifter, in order to meet the functional requirements such as gear lock and automatic P gear, the solution of solenoid valve and motor is added, which increases the complexity and cost of the shifter.
