Abstract

The invention discloses an ignition switch with a car key pull-forgetting prevention function. The ignition switch comprises a switch casing structure. An ejection bar (1) is arranged in the middle of a spindle (9), a movable contact piece (3) is mounted on the ejection bar (1), the lower portion of a contact at one end of the movable contact piece (3) corresponds to a public terminal contact piece (4), and the lower portion of a contact at the other end corresponds to a pull-forgetting prevention terminal contact piece (7). By means of the ignition switch, an independent non-pull reminding function is integrated on the ignition switch, and defects of the independent reminding function are overcome by only adding the ejection bar, a spring, the movable contact piece and the pull-forgetting prevention terminal contact piece. The structure is simple, and the reliability is high.

Description

technical field

[0001] The invention relates to an automobile ignition switch. Background technique

[0002] The key not pulled out reminder function of the car ignition switch is to integrate the original independent key not pulled out reminder function into the ignition switch. The so-called key not pulled out reminder function is to prevent all the people in the car from leaving the vehicle. Pull out the key, thereby causing serious damage. At this time, because the anti-forgetting switch on the ignition lock is not disconnected, the control unit will output a signal and make a sound to remind the driver. For forgetting switch. The original independent anti-forgotten switch needs to be composed of special micro switches, wires, connectors and other components, and a special installation structure and transmission structure are required on the lock body, which not only costs more, but also increases the cost of the lock body. The complexity reduces the reliability of th...

Embodiment

[0020] Such as figure 1 , there is a square hole at the top of the rotating shaft 9, which is used to install the interlocking pin of the lock body. There are two metal turntables installed on the outside of the rotating shaft 9. The upper end is a large turntable 10, and the corresponding three contact columns 12 are respectively connected to the IG1 terminal. contact piece, ACC terminal contact piece and common terminal contact piece 4 (B1), the lower end is a small turntable 11, and the corresponding two contact columns 12 are respectively connected to the ST (ignition) terminal contact piece and the IG2 terminal contact piece . A push rod 1 is arranged in the middle of the rotating shaft 9, which is in contact with the push rod in the linkage pin. The movable contact piece 3 is installed on the push rod 1, and the contact at one end of the movable contact piece 3 corresponds to the common terminal contact piece 4, and the contact piece at the other end Corresponding to t...
