Description

Displaying and monitoring device for vehicle lights

The utility model relates to the monitoring device of car lighting or signal lamp, is meant that specifically a kind of car bulb shows detector.

At present, whether the various light that automobile driver can't check vehicles in vehicle ' show normal, so that sometimes because of the light generation traffic accident that do not work.Walk out operator's compartment if stop specially and go to check that light shows situation, then be the thing of a not only time-consuming but also effort,, must turn round eight times more than around automobile such as only checking steering indicating light, and people of drg light can't check, must two people cooperate just and can carry out.Parking checking can not be in time so still more, and the light that is out of order shows as untimely finding, just may cause the generation of traffic accident.The monitoring device that several relevant automobile lamp of patent applied for shows, structure is comparatively complicated and unreasonable, is difficult to promote the use in practice.

The purpose of this utility model, provide a kind of need not to walk out operator's compartment just easily the various light of car check show that the simple in structure and rational car bulb of situation shows detector.

Solution of the present utility model is as follows.It has the single pole double throw switch of several coaxial interlocks, each single pole double throw switch all has a movable contact head end and " luminous " and " detection " two stationary contacts, " detection " stationary contact of one of them single pole double throw switch is connected to current-limiting resistance R, " luminous " stationary contact is on the shelf, and " detection " stationary contact of the single pole double throw switch of remaining coaxial interlock respectively links to each other with the negative pole of a light-emitting diode respectively, their " luminous " stationary contact, perhaps independent one each joins with the negative pole of a light-emitting diode respectively, perhaps more than one " luminous " stationary contact is linked to be a common point, each joins with the negative pole of a light-emitting diode respectively to allow common point again, the positive pole of the light-emitting diode that above-mentioned all and single pole double throw switch stationary contact join all is connected in a common point, and also has in addition the positive pole of at least one light-emitting diode and the other end of current-limiting resistance R to link to each other with this common point.

The utility model with foregoing circuit structure is when concrete the use, it is contained in a capsule is built in the automobile cab, all light-emitting diodes all are revealed on the mounting box panel so that observe, it is outer so that use manual manipulation to make the coaxial combined operation mechanism of several single pole double throw switch of coaxial interlock be exposed to the mounting box panel, and the movable contact head end and the direct supply on the automobile (12V or 24V) that will be connected with the single pole double throw switch of current-limiting resistance R join, and the non-power-of illumination on the automobile or signal lamp is extremely joined with the negative pole of the movable contact head end of remaining single pole double throw switch of the utility model device or " luminous " stationary contact or the light-emitting diode that do not link to each other with single pole double throw switch.We are also noted that simultaneously, the illumination on the automobile or the other end of signal lamp all join with power cathode, and the non-power-of wherein a part of illumination or signal lamp extremely also joins by the electric switch and the positive source of original control illumination or signal lamp on the automobile respectively.

In running car, the moving contact of the single pole double throw switch of several coaxial interlocks is placed respectively the gear that joins with " luminous " stationary contact, then the utility model is in the light show state.As long as open the electric switch of original control illumination on the automobile or signal lamp this moment, just can be or directly power the luminous demonstration of the work of making to illuminations all on the automobile or signal lamp through the original electric switch of automobile by single pole double throw switch.And if the moving contact of the single pole double throw switch of several coaxial interlocks is placed respectively the gear that joins with " detection " stationary contact, then the utility model is in the light detected state.The light of establishing by cable that need only original control illumination or signal lamp on the automobile this moment all turn-offs, then power supply constitutes a plurality of loops by current-limiting resistance R, single pole double throw switch, light-emitting diode and illumination or signal lamp respectively, if bulb and loop are normal, then under the metering function of current-limiting resistance R, each loop makes whole light-emitting diodes all luminous by very little electric current.Obviously, if which bulb or loop are out of order, then corresponding light-emitting diode just can not be shinny.Like this, the people is sitting in operator's compartment and need not gets off, but the just demonstration situation of car check light, to take appropriate measures.

Use the utility model to detect car bulb and show, both laborsaving saving time, in time convenient again, ensured the safety traffic of automobile, be the good assistant of automobile driver.It is simple in structure, installs rationally, is easy to promote in practice.

Below in conjunction with drawings and Examples the utility model is further specified.
