Problems solved by technology

Whether the ignition switch can accurately and reliably realize the functions, that is, the on / off of the power supply of the automobile electrical appliances, the start / off of the engine, directly affects whether the vehicle can be turned on / off normally and the safety during driving. Small size and high stability requirements, so accurate and reliable contact becomes the key, and the structural arrangement is also the direction of strengthening in recent years, and the ignition switch is a key part of the car, the ignition switch has no function or unstable contact, etc., will affect To the safety of the vehicle, it will also directly cause the vehicle to be unusable

Embodiment 1

[0021] Embodiment 1: as figure 1 In the shown embodiment, an automobile ignition switch structure includes a base 1 and a cover 2 arranged on the base, the space between the base and the cover forms a switch chamber 3, and the base is provided with fixed rivets 4. A number of gear position rivets 5, the inner ends of the fixed rivets and the gear position rivets are all in the switch cavity, and the outer ends of the fixed rivets and the gear position rivets are connected to the various gear circuits of the ignition switch through wires. A driving swivel 6 is provided inside, and a rotating hole 7 is provided on the cover, the driving swivel is connected to the base in rotation, the outer end of the driving swivel extends into the rotating hole, and the driving swivel A key socket 8 is provided on the top, and the key socket is opened at the outer end of the driving swivel. The driving swivel is provided with a transverse extension 9, and the base is provided with a fixed piec...

Embodiment 2

[0028] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as Figure 2 to Figure 4 As shown in , the drive swivel is provided with a reset top plate 25 for pressing the return torsion spring. When the drive swivel is in the "LOCK gear", "ACC gear" and "ON gear", the reset The top plate is separated from the return torsion spring; when the driving swivel rotates to the "START gear", the reset top plate presses the return torsion spring. Resetting the top plate can clearly return the working period of the torsion spring. When the driving swivel turns from "ON gear" to "START gear", the reset top plate starts to press the return torsion spring, so that the reset torsion spring will provide the recovery force. When the driver releases the car key, the reset torsion spring and the reset top plate will push the drive swivel back to the "ON position". When switching between other gears, the return torsio...

Abstract

The invention discloses an automotive ignition switch structure, and aims at providing an ignition switch which is reasonable in structure and high in overall stability and can be used for stably and effectively achieving rotation, contact and conduction and by which contact stability of a contact position is achieved and different contact pieces are distributed in a layered and regional manner. The ignition switch comprises a base, a cover shell and a switch cavity, wherein a static rivet and a plurality of shift rivets are arranged on the base, outer ends of the static rivet and the shift rivets are connected to each shift circuit of the ignition switch via wires, a driving rotation body is arranged in the switch cavity, a rotation hole is arranged on the cover shell, the outer end of the driving rotation body extends into the rotation hole, a key jack and a transverse extension part are arranged on the driving rotation body, a stator positioning base and a rotor positioning base are arranged on the base, a movable contact piece is arranged between the rotor positioning base and the transverse extension part and comprises a movable ring seat and a bridge convex connect piece, a movable contact spring is arranged between the movable contact piece and the transverse extension part, a static contact piece and a static contact spring are arranged on the driving rotation body, and the static contact piece is in contact with the inner end of the static rivet.

Description

technical field [0001] The invention belongs to the technical field of automobile electrical accessories, and in particular relates to an automobile ignition switch structure. Background technique [0002] The main function of the car ignition switch is to energize. It is generally installed on the lock mechanism of the car steering column. It is the main switch to turn on or off the car ignition coil circuit. It is also suitable for other electrical circuits in the car. Whether the ignition switch can accurately and reliably realize the functions, that is, the on / off of the power supply of the automobile electrical appliances, the start / off of the engine, directly affects whether the vehicle can be turned on / off normally and the safety during driving. Small size and high stability requirements, so accurate and reliable contact becomes the key, and the structural arrangement is also the direction of strengthening in recent years, and the ignition switch is a key part of the ...
