Rotary type electronic shifter and gear switching system

Abstract

The invention provides a rotary type electronic shifter and a gear switching system. The shifter mainly comprises a rotary knob, a driven wheel, a magnetic inductor and an electronic chip, wherein the rotary knob is provided with a sawtooth structure, and the driven wheel is integrated with a magnet. The sawtooth structure of the rotary knob and the driven wheel are meshed, and then the driven wheel is driven to rotate. In the process of use, an operator operates the rotary knob to drive the magnet on the driven wheel to rotate, the magnetic inductor determines the rotating angle of the magnet according to the change of a magnetic line of force and outputs corresponding electric signals to the electronic chip, and the magnitude of the electric signals is relevant to the rotating angle of the magnet. Furthermore, the electronic chip determines gears into which need to be switched according to the rotating angle of the magnet. On one hand, gear shifting is conducted in a non-contact mode; on the other hand, the magnetic inductor detects the rotating angle of the magnet without being affected by dust and other foreign matter in an external environment, and therefore adjusting accuracy of gear shifting is improved.

Description

technical field [0001] The invention relates to the field of automobile braking, and more specifically relates to a rotary electronic shifter and a gear shifting system. Background technique [0002] With the continuous development of the automobile industry, various types of electronic shifters have been applied in the automobile manufacturing industry. Currently, the electronic shifters on the market mainly include: gear lever type, knob type and button type. Among them, the knob-type electronic shifter is mainly used in luxury cars, and the button-type shifter is mainly used in small cars and small electric cars. [0003] There are mainly two types of electronic shifters currently on the market. 1. Direct contact shifter, 2. Grating shifter. [0004] Due to the impact of frictional resistance, the direct contact shifter has low reliability and short service life. Although the grating shifter has the advantage of non-contact, due to the shielding of the light emitter a...

[0004] Due to the influence of frictional resistance, the direct contact shifter has low reliability and short service life

Although the grating shifter has the advantage of being non-contact, due to the blocking of the light emitter and light receiver by foreign objects such as dust in the environment in practical applications, the shifting adjustment accuracy is low.
