Abstract

The invention discloses an ignition switching structure comprising a housing and an ignition rotor. A contact plate is arranged on the ignition rotor. A lock cylinder for driving the ignition rotor to rotate is arranged inside the housing; and the lock cylinder and the housing are in rotation connection. A key plugging hole is formed in the lock cylinder. A ball groove and a positioning structure are arranged on the ignition rotor. The positioning structure consists of a positioning ball arranged in the ball groove, a gear groove part arranged at the inner wall of the housing, and a ball pushing spring for pushing the positioning ball into the gear groove part; and the gear groove part includes a LOCK gear groove, an ACC gear groove, and an ON gear groove. In the corresponding ball groove and positioning structure, the positioning ball and the ball groove are in a sliding fit relation; and one end of the ball pushing spring is in contact with the positioning ball and the other end of the ball pushing spring is in contact with the ignition rotor. According to the invention, the ignition switching structure has the following beneficial effects: the structure is reasonable; the operation becomes convenient; the hand feeling during the rotation process is good; the positioning becomes accurate and stability is guaranteed; and because of a limiting protection structure, a phenomenon that the lock cylinder and the ignition rotor rotate before a key is inserted can be prevented.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an ignition switch structure. Background technique [0002] The car ignition switch is installed on the lock mechanism of the car steering column. It is the main switch to open or close the car ignition coil circuit. It includes lock cylinder, ignition rotor and other structures. Wherein the lock cylinder is used to insert the car key, and the ignition rotor connects the contacts arranged in each gear line through the contact conduction structure (contact sheet, contact plate) arranged on it, thereby realizing various functions. However, the current car ignition switch is still lacking in terms of gear position control, operating feel, and positioning stability. Contents of the invention [0003] The present invention aims to overcome the deficiencies in the prior art, and provides an ignition switch structure with reasonable structure, convenient operation, good hand feeli...
