Abstract
An anti-robbery taxi top light is an identification component for taxis. This anti-robbery taxi top light comprises a shell, two lights, a plurality of switches, a relay, a current converter and a power supply. The two lights are installed inside the shell one of which is the alarm light while the other is the normal riding light. One end of the riding light is connected with the positive pole of the power supply and one contact of the current converter through its switch, the normally-closed contact and main switch, and the other end is directly connected with the negative pole of the power supply. One end of the alarm light is connected with the other contact of the current converter. The current convert is connected with the normally open contact of the relay and with the positive pole of the power supply through the alarm switch and the main switch. The other end of the alarm light is connected with the negative pole of the power supply. The relay and the current converter are connected with the positive pole of the power supply through the alarm switch and the main switch and their return circuits are connected with the negative pole of the power supply. It is not easy to be noticed to send alarm with this anti-robbery taxi top light while facing robbers.
Description
Technical field
A kind of anti-snatch taxi dome lamp belongs to the taxicar mark component.
Background technology
Taxi dome lamp is the sign of taxicar, generally is contained in the top of taxicar.The incident of plundering taxicar in recent years happens occasionally.Because the ruffian faces the taxi driver directly, thereby in the robbery process, the taxi driver can't in time report to the police.
The utility model content
In order to make the taxi driver when meeting with robbery, can in time send alerting signal, the utility model spy has proposed a kind of anti-snatch taxi dome lamp.
This anti-snatch taxi dome lamp is made of ceiling light shell, two lamps, switch, relay, current exchanger and power supplys; Two lamps are contained in the ceiling light shell, and one of them is an alarm lamp, and another is the cruising lamp; An end of lamp normally closed interlock and main supply switch and the positive source by its switch, relay that travel links, and a contact with current exchanger links simultaneously, the other end directly and the negative pole of power supply link; One end of alarm lamp and another contact of current exchanger link, and the normally open contact of current exchanger and relay links, and link by alarm switch and main supply switch and positive source, and the other end and the power cathode of alarm lamp link; Relay and current exchanger link by alarm switch and main supply switch and positive source, and its loop and power cathode link.
When the taxicar cruising, total power switch closes.When needing ceiling light, the light switch that travels that closes, electric current opens ceiling light by main supply switch, relay normally closed interlock, the lamp that travels.When meet plundering, driver's alarm switch that can close, relay and current exchanger energising, relay disconnects normally closed interlock, and the normally open contact that closes extinguishes the lamp outage of travelling.Current exchanger is alternately connected alarm lamp and the lamp that travels, and they is glimmered back and forth, to reach the purpose of warning.When alarm switch disconnected, because the effect of relay, alerting signal can not stop yet, and has only the disconnection general supply, and reporting to the police just can stop.
Use this anti-snatch taxi dome lamp in the face of the robber time, to report to the police, and make it be difficult for discovering.
