Problems solved by technology

The gear position sensing elements commonly used in the existing electronic gear shifters use mechanical contact switches or switch Hall sensors. However, according to the analysis of actual conditions, it can be seen that the reliability of the electronic gear switch of the mechanical contact switch is not high, and the failure rate is high. The layout is inconvenient; although the switch H

Abstract

The invention discloses an auto electronic shifter assembly. The auto electronic shifter assembly comprises a support body, a gear plate, a circuit board, a gear sensing assembly, and a gear operation assembly, wherein the gear plate is clamped on the support body and forms a hollow cavity structure together with the support body; the circuit board is fixed in the support body; the gear sensing assembly and the gear operation assembly are arranged in the hollow cavity structure; the gear sensing assembly is connected with the circuit board; the gear sensing assembly consists of a first photoelectric sensor, a second photoelectric sensor and a shading sleeve; and the gear operation assembly consists of a gear knob cap, gear keys, a knob slider, a support plate, a gear base, a limiting tube, a spring sleeve, a return spring and a pressing block. The electronic shifter assembly has the advantages of high shifting reliability, convenient operation, small size and low cost.

Description

technical field [0001] The invention relates to an automobile shifter assembly, in particular to an automobile electronic shifter assembly. Background technique [0002] With the continuous development of green and environmentally friendly pure electric vehicles and hybrid vehicle technologies that combine environmental protection and power, shifters that use electrical signals as the control method have emerged. The gear position sensing elements commonly used in the existing electronic gear shifters use mechanical contact switches or switch Hall sensors. However, according to the analysis of actual conditions, it can be seen that the reliability of the electronic gear switch of the mechanical contact switch is not high, and the failure rate is high. The layout is inconvenient; although the switch Hall sensor can accurately sense the position, it requires a large number of sensors, a large layout space, and is prone to false triggering, resulting in high production costs; a...
