A vehicle ignition switch

Abstract

The invention discloses a vehicle ignition switch which comprises an upper casing, a rotation driving wheel, a lower casing and a bottom cover which are sequentially arranged from top to bottom; the relative positions of the upper casing, the lower casing and the bottom cover are fixed, the rotation driving wheel can rotate relative to the lower casing, a conductive reflux strip is arranged on the front side of the lower casing, a contact elastic piece is arranged on the back side of the lower casing, and the contact elastic piece extends to the front side of the lower casing, is arranged corresponding to the conductive reflux strip and can be in contact with the conductive reflux strip; the conductive reflux strip and the contact elastic piece are both provided with ignition branches; when the ignition branch of the conductive reflux strip is in contact with the ignition branch of the contact elastic piece, a vehicle is ignited; a driving curve surface is arranged on the back side of the rotation driving wheel, and the driving curve surface can be in contact with the contact elastic piece under the rotation action of the rotation driving wheel to enable the ignition branch of the conductive reflux strip to be in contact with the ignition branch of the contact elastic piece. The vehicle ignition switch has the advantages of more reasonable structure, smaller space occupation, more stable functions and longer service life.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle ignition switch. Background technique [0002] The car ignition switch is a very critical component in the car ignition system. Usually the ignition switch is assembled at the end of the mechanical lock base. The driver uses the key to drive the ignition switch through the lock cylinder assembled at the front end of the mechanical lock base to realize the start of the car engine. Start-stop function. [0003] In order to prevent drivers and occupants from forgetting to extract the key from the lock cylinder when they leave the car, usually the car will be provided with a reminder function for forgetting to extract the key. This function is usually realized by triggering a switch after the key is inserted into the lock cylinder, and this switch is called the key anti-forgetting switch. There are currently two anti-forget switch settings, a separate switch m...

AI Technical Summary

Problems solved by technology

Although the above-mentioned patent is provided with an anti-forget-out key function in the ignition switch, due to the use of a relatively old-fashioned electrical contact system, there are problems such as unstable electrical connection and low service life.

At the same time, the electrical contact system of the anti-forget function and the mechanical drive structure are in the same direction, which will cause the problem of unstable connection due to the large tolerance after the key is inserted.
