Abstract
The utility model discloses a turning warner, which comprises a casing and two terminals. A contact switch with electric heating wire, a buzzer and a wire are fixed in the casing, the buzzer is connected with two ends of the electric heating wire by the wire in parallel connection, a static plate and a dynamic plate of the contact switch are connected with two terminals respectively, and connected into control circuit of steering light of existing motor vehicle by the two terminals respectively. Comparing with current technology, the utility model has simple structure, easy realization and convenient installation, and can remind the driver to turn off steering light timely by buzz of the buzzer so as to reduce occurrence rate of traffic accident.
Description
Technical field
The utility model relates to a kind of turning news Chinese percussion instrument that is used for can sounding when self-propelled vehicle is turned and reports to the police.
Technical background
All be equiped with turning flash equipment on the general self-propelled vehicle, it is to be connected in series in the circuit by lead and master cock.When power actuated vehicle before turning, the driver can open steering indicating light, comes in this way forwards to transmit the message that this car is turned with back vehicle.But the untimely steering indicating light of closing of back driver in case turn makes the chaufeur of the vehicle at the place ahead and rear judge that this car travels situation by accident and the traffic accident that caused vehicle has brought great harm for people's property and life security.
The utility model content
The purpose of this utility model provides a kind of simple in structure, easy for installation, turning news Chinese percussion instrument that particularly can audible alarm.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is a kind of turning news Chinese percussion instrument, comprise shell and two binding posts, be provided with contact switch, buzzer phone and the lead of charged heated filament in the shell, described buzzer phone is connected in the two ends of heating wire in parallel by lead, the still of described contact switch is connected two binding posts respectively with moving plate, and is connected in series in the control circuit of steering indicating light of existing self-propelled vehicle by two binding posts respectively.
The contact switch of described charged heated filament can be made of heating wire, still and moving plate, and described heating wire is wrapped on the moving plate of contact switch, and the two ends of heating wire are connected with moving plate with the still of contact switch respectively.
After taking technique scheme, the utility model only needs to be connected in series in the control circuit of steering indicating light of self-propelled vehicle by binding post, and the buzzing that can realize buzzer phone is reported to the police and reminded chaufeur in time to close steering indicating light.Therefore relatively prior art, the utility model realization simple in structure, easy, easy for installation, and self-propelled vehicle has been overcome turn the back driver is untimely and close the harm that steering indicating light brings, thereby reduced the incidence of traffic accident.
Description of drawings
Accompanying drawing 1 is turned for the utility model and is interrogated the perspective view of Chinese percussion instrument;
Accompanying drawing 2 is turned for the utility model and is interrogated the schematic circuit diagram of Chinese percussion instrument.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model turning news Chinese percussion instrument is described in further detail.
With reference to the accompanying drawings, the utility model turning news Chinese percussion instrument comprises shell 1 and two binding posts 2.Be provided with contact switch K2, buzzer phone B1 and the lead of charged heated filament in the described shell 1.The contact switch K2 of described charged heated filament can adopt the matured product on the present market.This contact switch K2 is made of heating wire, still and moving plate, described heating wire is wrapped on the moving plate of contact switch, and the two ends of heating wire are connected with moving plate with the still of contact switch respectively, described buzzer phone B1 is in parallel with heating wire by lead, and the still of described contact switch K2 is connected two binding posts 2 respectively with moving plate.
During use, with the positive pole of binding post 2 connection+12V power supplys of the news Chinese percussion instrument of turning, the end of the master cock K1 of steering indicating light is connected on another binding post 2 and the self-propelled vehicle.So just this turning news Chinese percussion instrument is connected in series in the control loop of steering indicating light of self-propelled vehicle its schematic circuit diagram with reference to the accompanying drawings 2.After pressing master cock K1 before the driver driving turn inside diameter, heating wire, buzzer phone B1 and steering indicating light L1 conduction are connected, then heating wire begins heating, buzzer phone B1 rings, and because the resistance of heating wire is far longer than the resistance of steering indicating light L1, the undertension that is carried in steering indicating light L1 two ends to be lighting steering indicating light L1, so steering indicating light L1 is equivalent to short circuit and does not work.Because electrothermal wire heating's after expansion, the moving plate of compressing contact switch contacts with still, thereby causes the short circuit of heating wire and buzzer phone B1, makes buzzer phone B1 stop to ring, and steering indicating light L1 lights.At this moment heating wire turns cold gradually, makes two contact opens of contact switch K2.From and connected buzzer phone B1 and heating wire.Go round and begin again, " ticking " that buzzer phone B1 and steering indicating light L1 replace in the turning process always mutually rung and is glittering, closes taillight master cock K1 until the driver like this.
Claims (2)
