Description

The combined type digital key

The utility model relates to the digital key of a kind of combined type.

(applying date is on November 10th, 2000 at other a Chinese patent 00240050.2 of the Kuang Rui of our unit health, the TM deck and the TM card of motor vehicle digital anti-theft device were once described No. 43 bulletin of Patent Office), the TM deck is made up of stainless steel deck, copper core and plastic barrier cover, insulate between deck and the copper core.It is directly to contact the IC that the characteristic signal of TM card is passed to the digital anti-theft device by the TM card with the TM deck ₁In, be provided with the feature password of making of photoetching process in the TM card, be used for starting the reception controller; Described TM deck has the shell of a ground connection, and a metallic conductor with casing insulation is arranged in it, and a shape, size and the corresponding socket of TM card are arranged in the metallic conductor, TM deck delivery outlet and reception controller single-chip microcomputer IC ₁The input port connects, and another interface grounding wire is used to receive the electrode signal of TM card, when the TM card inserts the socket of TM deck, promptly the electrode signal of TM card is passed to the receiver input port.This TM card, the shortcoming of TM deck is: the TM card is arranged to a key separately, carries inconvenience; TM deck volume is bigger, needs the installing hole about φ 20mm of installed position brill of vehicle during installation, has destroyed vehicle, and the vehicle that those installation sites are restricted just is inconvenient to install as the men's clothing motorcycle simultaneously; The TM deck can't use the TM card of multiple model.

The purpose of this utility model is at above-mentioned shortcoming, provides a kind of combined type digital key, and it adopts TM chip contact holder and car electric door lock combination, replaces TM card, TM deck.

The digital key of combined type of the present utility model is by the key body, box body, lid, the TM chip, conducting rod, spring is formed, key body and box body, lid is that interference fits connects, between box body and the lid for fixedlying connected, be flexible connection between slide block and the box body, there is a shape at box body top center place, size and the corresponding cavity in key body lower end, correct under the key body when position of this cavity can make assembling and be positioned at this cavity, the TM chip is anodal to be connected with conducting rod, TM chip negative pole is connected with the key body, motor vehicle electric switch key core ground connection, the single-chip microcomputer IC of electric door lock panel and digital anti-theft device ₁The input port connects, and spring housing is movable the cooperation on conducting rod; Box body one side has a shape, size and the corresponding cavity of TM chip, the TM chip just in time was positioned at this cavity when the position of this cavity can make assembling, TM chip external diameter is interference fits therewith between the cavity, opposite side has a shape, size and the corresponding cavity of electric conductor, electric conductor just in time was positioned at this cavity when the position of this cavity can make assembling, and the electric conductor external diameter is movable the cooperation therewith between the cavity; There is a switching mechanism in the box body outside.

This switching mechanism is a shifting block that is positioned at box body away from that side of TM chip cavity, and the small column of a band endoporus is arranged on this shifting block bottom surface; On the box wall therewith the shifting block corresponding position have a strip groove; From then on the small column of shifting block bottom surface stretches out interference fits in the strip groove and entangles conduction body rod below small column, and this shifting block can move along this strip groove.

Box body has a lid that matches with port, and the supporting raised line of two band half round cut is arranged with box body cavity internal support raised line corresponding position in the lid cavity.

This digital anti-theft device and ignition is combined and solid envelope.

Adopt said structure, the electric door lock of TM chip and vehicle unites two into one, and replaces TM card, TM deck, by the single-chip microcomputer IC of digital anti-theft device ₁, software identification starts vehicle, and the digital anti-theft device is integral with the solid envelope of ignition combination, have simple in structure, only gather, volume is little, cost is low, portably use convenience, theftproof height, compliance are good, the advantage of the former vehicle of minimizing destruction.Can be widely used in the digital anti-theft device of motor vehicles, be particularly useful for the digital anti-theft device of motorcycle.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
