Abstract
The utility model relates to an anti-theft alarming device for a vehicle, comprising a switch circuit which takes a relay as a kernel, and the switch circuit can control the communicating of a language circuit and a vehicle speaker circuit and the breaking of a vehicle engine low voltage ignition circuit. The switch circuit also comprises a mechanical early warning switch which is matched with a vehicle door lock and a plurality of alarm contactors and anti-theft switches which are arranged on doors, an engine cover, oil tank, etc. The utility model has simple and reliable setting and canceling of the early warning information, entering into the early warning status has no electric power consumption, and the utility model has the alarm functions of anti-theft, anti-rob, etc.
Description
The utility model relates to a kind of anti-multifunctional warning device of robbing of automobile burglar that is used for.
Chinese patent CN2074732U disclose a kind of " car alarm " it by silicon control, relay, resistance, electric capacity, mechanical delay device and mechanical switch, contactless switch is interrelated and insert in the automobile circuit, trigger contactless switch by external force and produce the anti-theft alarm effect.Owing to adopted mechanical delay device, the setting of its early warning information is quite inconvenient with releasing.
The purpose of this utility model is to provide a kind of and not only car load is had antitheft effect, can both play protective action to all sites of packing contact, the early warning setting, eliminates multi-purpose vehicle(MPV) anti-theft anti-robbery alarm device very easily.
Above-mentioned purpose of the present utility model is to realize by such structure: promptly it comprises with the relay being the switch circuit of core, control sound circuit, it is characterized in that switch circuit comprises normal start tool early warning switch with it, it is connected on the power output end positive pole, early warning switch relay and often drive secondary contact and be serially connected between mechanical early warning switch and the ground is parallel with some Alarm contactors described often opening on the secondary contact; After often driving secondary contact and the alarm switch relay coil is connected, another of early warning switch relay be serially connected between mechanical early warning switch and the ground; One normally closed contact of alarm switch relay is serially connected in the automotive engine low tension ignition circuit, and its another open contact is serially connected in the electric automobile horn circuit, and voice produce on the loop of circuit, is parallel with Chang Kaifang on the described open contact and robs switch.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides an indefiniteness.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a circuit structure diagram of the present utility model;
The structural representation of accompanying drawing 2 Alarm contactor AN;
Accompanying drawing 3 is the structural representation of mechanical early warning K switch.
Referring to Fig. 1: early warning switch relay J

2-2Connect the current supply circuit and the sound circuit KD of electric automobile horn, electric automobile horn is yowled, the rattler SP of sound circuit sends the integrated alarm signal of " someone steals car, catches a thief ", in foregoing circuit, the KD series speech IC chip that sound circuit can adopt Xiao Shan brilliant outstanding electron tube group in Zhejiang to produce.For preventing that vehicle and chaufeur be robbed, at J
2-2Go up and joint defence misfortune K switch
1, this switch can be installed in the inferior shelter, seat of chaufeur, and in case of emergency chaufeur can make its closure rapidly.
Referring to Fig. 2, Alarm contactor AN often opens micro-switch 2 by housing 1, the indoor contact support spring of contact 3 and contact 4 constitutes, the contact of wherein normally closed micro-switch 2 be positioned at contact 3 under, when contact is moved down by external force, withstand the contact of micro-switch, make its disconnection.In order to guarantee the firm of Alarm contactor, the contact chamber of contact 3 and fine motion are opened 2 and all are loaded in the housing 1 with epoxy resin.Alarm contactor can be installed in door case, bonnet, and back box lid and fuel tank etc. is located, the lead concealed installation, the micro-switch that Alarm contactor adopted can adopt the JW-11 type.
Referring to Fig. 3, mechanical early warning K switch is by housing 7, cam 5, and micro-switch 6 constitutes.There is a supported by springs compressing tablet 8 below of its cam, and when the cam rotation, compressing tablet is pressed in or leaves the contact of micro-switch 8 times, and makes its closure.Described micro-switch, cam are encapsulated in the housing, and whole mechanical early warning switch directly is set on the lock core of car door, and on line adopts concealed installation, and chaufeur adopts key drive cam rotation to make annunciator enter alert status.Described micro-switch can adopt JWL
2-11 types.
The utility model adopts 12 volts of direct supplys, and this power supply can directly pick out from automobile storage battery.
Can summarize the utility model by above description has the following advantages:
1. simple in structure, easy for installation, car load and circuit there are not any harmful effect.
The setting of early warning information with remove simplyr than like product, and enter alert status and do not have power consumption.
3. safe in utilization, dependable performance, not only car load and operator's compartment there are antitheft effect, and can both shield positions such as engine, fuel tanks.
4. antitheft effect is not only arranged, and can prevent to rob car, the jogging car prevents to climb car and steals goods.
5. purposes is wide, except that being used for power actuated vehicle, also can be used for family and financial department antitheft, report to the police, the anti-misfortune.
