Abstract

The utility model discloses an automobile ignition key mechanism with an engine anti-theft chip. The automobile ignition key mechanism comprises a handle and a metal gear body, wherein the automobile ignition key mechanism further comprises a bracket which is connected with the metal gear body and is encapsulated in the handle; and a hole position for the installation of the chip is arranged at the rear part of the bracket. According to the key mechanism, disclosed by the utility model, reliability of the chip is improved efficiently, reliably and effectiveness of the whole engine anti-theft system are well guaranteed, service life of the chip key is greatly prolonged and increased, risk of un-starting of the engine caused by invalidation of the key chip is reduced and product reliability is improved; meanwhile, due to the use of the plastic bracket, area of the metal gear body encapsulated inside the handle is reduced, metal gear body material is reduced, cost is saved efficiently and key weight is lightened.

Description

A kind of automotive ignition key mechanism with the engine anti-theft chip

Technical field

The utility model relates to a kind of automotive ignition key mechanism with the engine anti-theft chip.

Background technology

At present, known automobile key generally all partly adds key metal-toothed body portion two parts by key handle and forms.The antitheft of car body mainly is to lean on the coupling of shaped as key bit and car upper lock core whether to carry out release and unblank.Hold the key entering car door of identical profile of tooth in case that is to say the people, promptly can use this key ignition trigger motor, car is stolen easily.For utilizing master key or copy key etc., the person of avoiding theft opens car door, and the ignition trigger motor, stealing vehicle, people have adopted the IMMOBILIZER engine theftproof system to stop the similar difficult generation of stealing.Its specific practice promptly adds chip in automobile key, utilize the password of key chips and engine anti-theft locking module password to mate the starting of controlling motor, to reach the purpose of antitheft.For the automobile that anti-theft locking system of engine is housed, even the car stealer opens the car door automobile that can not ato unit drives away.Because the key of engine theftproof system microarray strip occupies very important effect in system, the mounting means of chip, the position, and be injected into stability and the reliability that the interior reliability standard of handle will directly influence engine theftproof system work.Traditional way is directly chip and key metal denticle to be positioned over directly injection mo(u)lding in the injection mold.The shortcoming of this way is: 1. the chip position skew causes the communication reliability not high.Chip position is influenced and change by plastic flow property when injection moulding, easily, departs from or tilts, and causes the chip communication failure easily.2. chip is influenced by elevated temperature heat to cause chip impaired, and communication is not smooth.During injection moulding, the plastic liquid of temperature flowing directly is wrapped in around the chip chip, causes chip temperature sharply to rise in mould, makes chip impaired when serious, causes communication not smooth.The metal denticle be wrapped in the spoon bigger interior metalwork area.Automobile key metal-toothed body portion is generally the Alpaka material.Material cost is higher.And, must the metal denticle be had enough encapsulate areas to encapsulate inside at spoon in order to make handle and metalwork injection mo(u)lding reach reliable intensity.

The utility model content

The utility model purpose is to overcome the deficiency of prior art; A kind of automotive ignition key mechanism with the engine anti-theft chip is proposed; Prevent that effectively chip position is movable or depart from, simultaneously the plastic liquid of temperature flowing directly encapsulate on chip, thereby guarantee that chip does not receive temperatures involved; Improve the reliability of chip, thereby promoted the reliability and the safety of whole engine theftproof system.

Technical scheme: for solving the problems of the technologies described above; A kind of automotive ignition key mechanism that the utility model proposes with the engine anti-theft chip; Comprise handle and metal denticle; Also comprise a support, described support is connected with the metal denticle and encapsulate is injection-moulded in the handle, is provided with the position, hole that is used to install chip at described support rear portion.

Be provided with draw-in groove in described support front portion, be provided with back-off in the draw-in groove and be used for buckle metal denticle.

The size of described Kong Weiyu chip, big or small corresponding.

Described support is the PP moulding.

Beneficial effect: a kind of automotive ignition key mechanism of the proposition of the utility model with the engine anti-theft chip, do not need complicated processing technology and assembly equipment, can easily, effectively prevent the offset of chip in the Shooting Technique process; The too high defective such as impaired of temperature, its structure design is ingenious, and technological design is reasonable; Effectively raise the reliability of chip, thereby well guaranteed the reliability and the validity of whole engine theftproof system, the application life that prolongs and improved chip key greatly simultaneously; Reduced the risk that motor that the key chip failure causes does not start; Improved product reliability, simultaneously because the use of plastic stent has reduced the area of metal denticle at the inner encapsulate of handle; Subdued metal denticle material, effectively thrifty cost has also alleviated key weight.

Fig. 2 is the front view of the utility model plastic stent;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is that the utility model is assembled to spoon last structure principle chart;

1. support, 2.Handle, 3.Chip, 4 metal denticles, 5. position, hole, 6. draw-in groove.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

Like Fig. 1, Fig. 2, and shown in Figure 3; Can very clearly understand the structure of plastic stent 1, support 1 is oval bluff body, is the PP moulding; Leave the position, hole 5 of cartridge chip 3 in this middle part, support 1 rear portion, this position, hole 5 is corresponding with shape, size, the size of chip 3, makes chip 3 also assemble firmly in the load hole position 5 smoothly; Any noise can not rocked and produce to control through size and tolerance after making chip 3 be assemblied in the position, hole 5, and as can be seen from Figure 3 the draw-in groove 6 of " L " shape about support 1 front portion is provided with back-off in the draw-in groove 6; Make after 4 assemblings of metal denticle, tip upside down in the draw-in groove 6, can not break away from from support easily.Assembly structure schematic diagram 4 through the utility model again, we can find out, the support 1 that assembles chip 3 and metal denticle 4 is put into key handle 2 together and is carried out the encapsulate injection moulding, finally forms the key mechanism assembly of microarray strip 3.The embedded injection moulding mode of this increase support 1 has not only improved injection moulding intensity, has subdued metal denticle 4 and has stretched into the contact area in the handle 2; Save material, reduce cost weight reduction; The more important thing is and protected semiconductor chip 3, make it more stable in injection moulding process, reduced the probability that in injection moulding process, causes chip 3 to lose efficacy; Thereby guaranteed the reliability of engine theftproof system, effectively reduced, the risk that the 3 bad motors that cause misfire because of key core.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
