Description
Technical field
The present invention relates to vehicle switch field, more particularly, to a kind of ignition switch structure with key insertions function.
Background technology
Automobile ignition switch is rotated by rotor so that the circuit turn-on on travelling contact and stator on rotor, so as to
Realize the conducting of each gear of ignition switch (ACC, ON and START).The ignition switch of existing design, is provided with key detection
With switch, for detecting the insertion of key.Existing key detection switch can be divided into two kinds of forms, and one kind is to be provided separately within igniting
Detection switch structure outside switch, another kind are integrated in the detection structure of the key in ignition switch.It is arranged in outside ignition switch
Structure, volume is big, takes up room, and individually designed high cost, and the key detection structure for being progressively integrated formula at present is taken
Generation.
And the key detection structure of existing integrated form is due to small volume, compact internal structure, therefore, the precision of each part will
Ask very high.If Chinese Patent Application No. is 200910004664 to disclose keys detection in a kind of in the ignition switch with connecing
Point mechanism not only simply but also had the switch device for key operation of high reliability.There is bottom concavity that there is tubular axle portion and maintaining part
And be formed on rotatable runing rest, it is above-mentioned have in the concavity of bottom slippingly insert because of the insert action of key and quilt
The slide block for pushing, and intermediate connecting part is fixed on the slide block, the intermediate connecting part has flexure strip.On runing rest
Fixed movable contact component, the sliding part of movable contact component can be relative to being disposed on the inner bottom surface of storage concavity of frame
Electrode pattern slide, and along be formed in insertion concavity on narrow concavity inner wall arrangement from movable contact component
Start extended extended piece.Then, with the sliding of slide block makes flexure strip or contact with extended piece so as to
Elastic Contact and slip are carried out, or is departed from which, and, as the rotation of runing rest makes sliding part change to electrode pattern
Contact position.This application is relative with original design, has greatly improved really, but centre is additionally provided with the slide block of the structure
Connection member, it is from description and accompanying drawing it is known that the intermediate connecting part is a U-shaped elastic piece structure, yielding, use
Short life；And assembly precision has high demands, slightly deviation, it is most likely that cause inductive switching insensitive.Therefore, the construction of switch is steady
Qualitative difference, service life are short.
The content of the invention
It is an object of the invention to provide a kind of ignition switch structure with key insertions function, solves existing ignition switch knot
Middle interconnecting piece required precision on structure is high, changeableness, meanwhile, using the problem of contact stabilization difference..
The technical solution adopted for the present invention to solve the technical problems is：A kind of knot of the ignition switch with key insertions function
Structure, including base, are provided with one group of inserts on base, be arranged in base rotatable switch block, and being inserted in switch block can be along turning
The slide block of block axial movement, is provided with return spring between slide block and switch block；Contact chip I and contact chip are provided with the switch block
II, the contact chip I and contact chip II in sliding process realize switching on and off with inserts；It is provided with the contact chip I
Butt strip I, is provided with butt strip II on contact chip II, promotion butt strip I and butt strip II is provided with the slide block makes two pairs
The nip portion of contact pin contact conducting；When key inserts switch block, band movable slider is moved downward, and makes nip portion extrude two butt strips,
Make butt strip I and butt strip II overlap joint conductings.
Specifically, the butt strip I is positioned at the top of butt strip II；The nip portion is to be arranged on the top of slips end
Post, when key insert switch block when, band movable slider move downward, fore-set drive top butt strip I move downward, so as to lower section
Butt strip II overlap joint conducting.
To improve the contact stabilization and durability of butt strip, it is additionally provided with below switch block for supporting butt strip II
Support spring.
Further, the bottom of the base is additionally provided with a fixed seat rotated with switch block, the support bullet
One end of spring is supported in fixed seat.
To improve the stress balance of butt strip, the fore-set is symmetrically set with 2, the front end of the butt strip I
For 2 separate shell fragments, each shell fragment is located in one of the lower section of fore-set respectively.
Good to ensure butt strip contact, the butt strip II is the slab construction that centre is provided with that return spring avoids hole.
Beneficial effects of the present invention：Coordinated by the nip portion on the contact chip I on switch block, contact chip II and slide block, made
Contact chip I and contact chip II on switch block overlaps conducting so as to detect the insertion of key.By the direct effect of slide block so as to
The intermediate member between slide block and switch block is reduced, while cost-effective, the assembling due to reducing part makes assembling more square
Just, it is in hgher efficiency.Meanwhile, from documents, intermediate member is U-shaped elastic piece structure, and assembly precision is high, and is easily deformed,
Affect service life, the application structure butt strip to shift to install up and down, turn on two docking oblique cut graftings by pushing for push rod,
It is simple and reliable for structure, and precision prescribed is low, it is convenient to process.The push rod is symmetrical arranged 2, and one is that the stress for ensureing push rod is put down
Weighing apparatus, meanwhile, two elastic piece structures also cause the contact of elastic contact chip more stable, it is to avoid one of them contact for damaging and causing
The situation that piece I and contact chip II can not be turned on occurs.Described support spring supports the butt strip II of lower section, and it is right to ensure that
The stability of contact pin I and butt strip II contacts.The butt strip II is designed using slab construction, can increase the contact of butt strip
Area, it is ensured that contact conducting well with butt strip I.
Below with reference to drawings and Examples, the present invention is described in detail.
