The utility model can be installed in the shelter of auto body, and good concealment does not at ordinary times influence the outward appearance of automobile, also is difficult for being found, and also is difficult for obscuring mutually with other telltale.When the automobilist finds dangerous or is in danger, can send signal in time, crowd around making or distant place are heard or are seen alerting signal, make the driver can realize saving oneself, rescuing mutually.The utility model is simple in structure, easy to install, can be assemblied on any transport vehicle, to guarantee drivers and conductors and passenger's safety.

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is the plate structure scheme drawing that rises and falls of the present utility model

Accompanying drawing 3 is flash light warning circuit figure of the present utility model

Accompanying drawing 4 is loud speaker warning circuit figure of the present utility model

Below in conjunction with embodiment, the utility model is further specified:

Embodiment 1: as accompanying drawing 1,3, shown in 4 warning flash light XD of the present utility model, alarm speaker RL are installed in headstock or the tailstock or vehicle body one side of automobile by lead, flash light XD particularly reports to the police, should note and to conflict mutually on colored and position with other indicator lamp, should accomplish eye-catching as far as possible.With flash light alarm switch K ₁With loud speaker alarm switch K ₂Be installed in driver's hand or the position that pin can conveniently touch by the lead connection, flash light XD and loud speaker RL can use separately, also can use simultaneously.

The working process explanation of warning flash light XD, as shown in Figure 3

When connecting K switch with hand or pin ₁The time, multi-vibrator BG ₁, BG ₂Work, BG ₂When collecting electrode was in high potential, voltage was through resistance R ₅Be added to switching valve BG ₃Base stage, make switching valve BG ₃Work, flash generator is connected in the contact 1,2 of relay J, and flash light XD begins the flash of light of reporting to the police.

The principle of work of alarm speaker RL, as shown in Figure 6: when connecting K switch with hand or pin ₂The time, the output signal of signal generator inputs to low frequency amplifier through coupling, i.e. IC ₁Integrated circuit work, alerting signal is through capacitor C ₃Be added to IC ₂ Integrated circuit block 3 ends make LF voltage and power amplifier work, and output signal is through capacitor C ₁₀Be added to loud speaker RL ₅On, make speaker operation, sounding alarm.

In the present embodiment, the formation of loud speaker warning circuit, as shown in Figure 4, wherein signal generator is by IC ₁-KD9561 music alarm integrated package, R ₆S-f is adjusted resistance R ₇, R ₈Divide the piezoelectricity group, feed through capacitor C ₄Form.Low frequency amplifier is by ic chip ₂AN214, defeated.Go into coupling capacitor C ₃, input end divider resistance R ₉, R ₁₀, R ₁₁, feed through capacitor C ₅, C ₆, C ₇, C ₉, bypass resistance R ₁₂, feedback condenser C ₈, output coupling capacitor C ₁₀, power supply filter capacitor C ₁₁Form.

In the present embodiment, main case is to be made by plastics or metal, can be installed on the position of seat cushion bottom.Ic chip ₂AN214 and music alarm ic chip ₁KD9561 belongs to prior art

Embodiment 2: the main purpose of present embodiment is to realize that warning flash light XD's is hidden, thereby designed the plate that rises and falls, as shown in Figure 2, flash light XD is contained on the lamp socket 11 of the plate that rises and falls, the plate that rises and falls is fixed on the boundary position on chassis of vehicle body, 12 of its handles are installed on driver's hand or the position that pin can contact, and the flash light switch then makes depression bar switch 6 into, connect warning flash light K switch with depression bar switch 6 ₁, during use, when the driver acts on the handle 12 with hand or pin, make the portable plate 10 of the plate that rises and falls do 90 ° rotation downwards by level attitude by backguy 3, the portable plate 10 that flash light XD is housed is exposed to outside the vehicle body.Because depression bar switch 6 is under pressure, make the flash light K switch simultaneously ₁Closure, flash light is flashing light alarm then.5 is the fastening nail on the adapter plate 4; 9 is the bullet Huang on the portable bar 8.

Other structure of present embodiment and principle of work and embodiment 1 are identical.
