Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the purpose of this utility model, feature and advantage are had deep understanding.

Description of drawings

Fig. 1 is the block scheme of alarming device for automobile anti-theft;

Fig. 2 is the electrical schematic diagram of controller;

Fig. 3 is the electrical schematic diagram of wireless launcher and annunciator;

Fig. 4 is the constructional drawing of bogie type mechanical switch.

The specific embodiment

With reference to Fig. 1, the utility model alarming device for automobile anti-theft is provided with power supply 1, is installed in signal picker 2, the controller 3, the wireless launcher 4 that link to each other successively with it on the vehicle body and is positioned at car owner's annunciator 5 on one's body.

With reference to Fig. 4, signal picker 2 adopts the bogie type mechanical switch, it comprises shell 21 with upper and lower opening, built-in metal segment 22, be fixed in segment 22 opening parts has the support 23 of conical central hole and is installed in the Metal Ball 25 that has pipe link 24 on the support 23, wherein, Metal Ball 25 is outer is provided with the conduction body 26 that is fixed on support 23 lower ends and insulation and is wound on coil 27 on the conduction body 26; Segment 22 is connected with weight 28 by shell 21 under sheds; Shell 21 inner chambers one side is equipped with electromagnet A, on the car body below the weight 28 electromagnet B is housed.In the present embodiment, metal segment 22, pipe link 24, Metal Ball 25 and conduction body 26 are iron.In other embodiment, pipe link 24 also can replace with " nano wire ", iron termination should be arranged to be supported on the support 23 on it.

With reference to Fig. 2 and Fig. 3, controller 3 comprises relay J 1, J2, J5 and a time relay sj, and it is subjected to the contact J1-3 control of car door interlock switch K1 (four series connection), bogie type mechanical switch K4, audio-switch K5 and J1 respectively.The coil XQ of the time-delay disjunction contact SJ1 of time relay sj control bogie type mechanical switch, the make contact electromagnet A of SJ2 control bogie type mechanical switch of time-delay, electromagnet B is controlled by automobile key switch K2.

Wireless launcher 4 has two parts: one, comprise the electronic switch that aerotron BG1, resistance R and relay tip J1-2, J2-2, J5 form, thyristor VS and wireless transmitter module A1; Two, comprise relay tip J1-1, J2-1 and wireless transmitter module U1.The power supply of wireless launcher 4 is accepted the control of car owner's theft-proof remote control K switch 0.

Annunciator 5 also has two parts: one, comprise a wireless receiving module A2 and a direction finder (known products); Two, comprise wireless receiving module U2 and the electronic switch of forming by aerotron BG2, BG3, thyristor VS and loud speaker Y.

Annunciator also is provided with theft-proof remote control K switch 0 for the car owner.

In the present embodiment, signal picker 2 also adopts car door interlock switch and audio-switch simultaneously.Four car doors are respectively equipped with interlock switch, and two audio-switches are equipped with in the vehicle body left and right sides.

Specify the working process of device below:

1. enter the state of alert

Whole car door interlock switch K1 closures, J1 gets electric, the J1-3 disjunction, the SJ dead electricity, its magnetic attraction disappears.Contact SJ1 makes coil XQ delay cut-off, and Metal Ball is put down; SJ2 connects electromagnet A time-delay, and segment will be delayed time and be changed the state that is fixed.

Simultaneously, J1-1 connects, and wireless transmitter module U1 work is sent signal to efficient range closely.Wireless receiving module U2 received signal, its output 3 is low level, and the electronic switch of being made up of aerotron BG2, BG3 turn-offs, and thyristor VS and loud speaker Y do not work.

Meanwhile, J1-2 connects, and the electronic switch of being made up of aerotron BG1, resistance R and relay tip J1-2 turn-offs, and thyristor VS and wireless transmitter module A1 do not work.

2. enter alarm condition

In the time of beyond the car stealer shifts out car closely efficient range, the state of alert of warning device can be destroyed, and after wireless receiving module U2 did not receive signal, its output 3 became high level, and electronic switch is connected, thyristor VS conducting, loud speaker Y sounding.This process car stealer does not also know.Because of the car owner is prompted from car far excessively, can in time find stolen.This alarm procedure can reach the car stealer car is shifted out scope about 50 kilometers.

When the people lifted car body (as stealing wheel), bogie type mechanical switch K4 connected, and coil XQ is charged, and iron cover 26 is inhaled moving Metal Ball 25 and kept attracting state.Simultaneously, J2 gets electric, and J2-2 makes thyristor VS conducting, wireless transmitter module A1 work, and wireless receiving module A2 can provide warning.

When the people for example smashes glass for vehicle window and sounds, audio-switch will make K5 connect, and J5 gets electric, and in like manner, J5-1 makes thyristor VS conducting, wireless transmitter module A1 work, and wireless receiving module A2 can provide warning.

When the people opens car door, the K1 disjunction, the J1 dead electricity, J1-1 and J1-2 all open, and wireless transmitter module U1 does not work; But resistance R makes BG1 because of the positive bias conducting, thyristor VS and wireless transmitter module A1 work, and wireless receiving module A2 can provide warning.

3. the releasing state of alert

Car door interlock switch K1 disjunction, the J1 dead electricity, the J1-3 closure, SJ connects, and its magnetic force picks up Metal Ball 25; Time-delay disjunction contact SJ1 makes coil XQ delay cut-off; The time-delay SJ2 that makes contact makes electromagnet A time-delay adhesive and decontrols segment 22.

Automobile key switch K2 will control electromagnet B fixes weight.
