Operation method and device of combined push-push switch

Abstract

The invention provides an operation method of a combined push-push switch. Multiple positions are set, and different positions correspond to different control signals; an ignition key reaches the different positions by reciprocating in an ignition switch so as to generate control signals of different stages. The number of push-push switches to be integrated or an integration way is determined according to the logic requirement of a control signal started by a traffic tool. Meanwhile, a corresponding operation device can set a mechanism to run at different stages as required, and the mutual restriction intensities among internal parts are different.

Description

technical field [0001] The invention relates to a control signal generating method and a corresponding mechanism for a vehicle, in particular to an ignition switch mechanism for an ignition system of an automobile. Background technique [0002] The signal control switch used for automobile ignition usually has the following types: [0003] 1. Insert the ignition switch key into the ignition switch lock. Rotate the key to different positions in the lock to generate a series of control signals to the ignition system, followed by: OFF, ACC, START, ON, to start various system power supplies on the car and maintain the car in different operating states Control status of various system power supplies. [0004] The main problems of this scheme are: 1), the mechanical key needs to be exposed to the car lock. When an accident occurs, the exposed mechanical key is likely to cause injury to the driver. 2) The ignition process operated by the driver is relatively complicated, and th...

AI Technical Summary

Problems solved by technology

[0004] The main problems of this solution are: 1), the mechanical key needs to be exposed to the car lock

When an accident occurs, the exposed mechanical key is likely to cause injury to the driver

2) The ignition process of the driver's operation is relatively complicated, and the scheme has relatively high requirements for the operation accuracy

3) The reliability of the contact system of this scheme is not high, and there is a quality risk

4), need more installation space

[0006] The main problems of this scheme are: 1), the operation action has no sense of rhythm

It takes a while from pressing the switch until the engine starts, creating a lag effect

3) High cost

[0008] The main problems of this solution are: 1), the operation movement is direct push, it is easy to push the ignition switch from position 1 to position 3 and skip the middle position 2, resulting in misoperation

2) The mechanical restraint strength of the ignition switch on the ignition key is fixed. When the car is running, it is easy to bear the impact. In this state, the ignition key still has no auxiliary restraint reinforcement, and it is easy to fly out of the ignition switch.

If auxiliary constraints are added to improve reliability, it means higher cost

3) When operating the ignition switch to move in different positions, the sense of rhythm is not good

4) Limited by the space and the length of the ignition key, it is difficult to expand more positions to generate more different position signals
