Description

Car bulb shows detector

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

At present, whether the various light that the car stand person of sailing 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, it then is again the thing of a not only time-consuming but also effort, such as only checking steering indicating light, must turn round eight times more than around automobile, and people of drg light can't check, must two people cooperate just and can carry out, parking checking can not be timely so still more, and the light that is out of order shows as untimely finding, and just may cause the generation of traffic accident.The monitoring device that the good several relevant automobile lamp of patent applied for shows, structure is comparatively complicated and unreasonable, be difficult to promote the use in practice, my Granted publication of application number is CN2176287Y " a car bulb demonstration detector ", though overcome the above-mentioned shortcoming that existing car bulb shows monitoring device preferably, but still had unsatisfactory part.Its subject matter is, because it has adopted the single pole double throw switch of tens coaxial interlocks, and the contact of the contact component of this switch is bad, by big electric current the time, be easy to generate electric arc and burnt gradually because of ohm heating, this increases contact resistance again conversely, form the vicious circle that further heating is burnt, cause influencing the normal operation that light shows testing circuit, its result must influence the due safety performance of whole demonstration detector; In addition, the single pole double throw switch of tens larger volumes is fitted together, and makes that the volume of whole demonstration detecting device is very big, and the installation profile seems very not attractive in appearance.Therefore, this car bulb shows that the structure of detector awaits further to improve.

For this reason, the purpose of this utility model, be provide a kind of need not to walk out operator's compartment just easily the various light of car check show that the car bulb that the simple and reasonable and safe and reliable again performance of situation is improved shows detector, also make the less and good looking appearance of its installation volume simultaneously.

Solution of the present utility model is as follows.It has a plurality of small-sized DC relays and the quantity a plurality of light-emitting diodes more than the small-sized DC relay, one end of a normally open contact of each DC relay is connected with the negative pole of a different light-emitting diode respectively, the other end of these normally open contacts or be connected with an end of the line bag of place DC relay respectively, perhaps be connected with the negative pole of the light-emitting diode of remainder respectively more respectively with after an end of the line bag of place DC relay is connected, and the positive pole of all light-emitting diodes all is connected in a common point, and having an end that is used for the single-pole single-throw switch (SPST) of light demonstration detection control also to be connected the common point of these light-emitting diode positive poles in addition, the other end of single-pole single-throw switch (SPST) then is connected with a current-limiting resistance.

The utility model with said structure is when concrete the use, be contained in it in capsule and place automobile cab, all light-emitting diodes all are revealed on the mounting box panel so that observe, to be used for light and show that the operating knob that detects the single-pole single-throw switch (SPST) of controlling usefulness is revealed in outside the mounting box panel so that use manual manipulation, and the positive terminal of direct supply (12V or 24V) on the other end of current-limiting resistance and the automobile should be connected, also the non-power cathode coupling end of the illumination that needs on the automobile to detect or signal lamp should be connected with the negative pole of the light-emitting diode of the utility model device respectively simultaneously, the coupling end of the line bag of all DC relay of joining with the light-emitting diode negative pole in the utility model device and its normally open contact is connected with the non-positive source coupling end of electric switch of original control illumination or signal lamp on the corresponding automobile respectively again, we also note that the following fact simultaneously, be that the illumination on the automobile or the other end of signal lamp are connected with power cathode, and wherein the non-power cathode coupling end of part illumination or signal lamp also is connected with positive source by the corresponding electric switch of original illumination or signal lamp on the automobile respectively.

In running car, place open position promptly during " luminous " position the single-pole single-throw switch (SPST) of the utility model device, then the utility model device is in the light show state.As long as open the electric switch of original all control illuminations on the automobile or signal lamp this moment, just can make all DC relay get electric and its normally open contact closure, so just can through original electric switch on the automobile or through the closed path that normally open contact provided of original electric switch on the automobile and DC relay to corresponding illumination on the automobile or signal lamp power supply, the luminous demonstration of the work of making.And if place make position promptly during " detection " position the single-pole single-throw switch (SPST) of the utility model device, then the utility model device is in the light detected state.The electric switch 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, single-pole single-throw switch (SPST), light-emitting diode and illumination or signal lamp respectively, if bulb and loop are normal, then under the metering function of current-limiting resistance, each loop only makes whole light-emitting diodes all luminous by very little electric current.Obviously, if which bulb or fault has appearred in which loop, then corresponding light-emitting diode just can not be luminous, thus the maintenance of prompting chaufeur.Like this, the people is sitting in the operator's compartment and need not gets off, and the just demonstration situation of car check light easily is to take appropriate measures.

Use the utility model device 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.Compare for CN2176287Y " car bulb demonstration detector " with Granted publication number, the single pole double throw switch that replaces the bigger coaxial interlock of many volumes with the less DC relay of many volumes, this device volume is reduced, good looking appearance is installed, the more important thing is the normally open contact closure of relay after contact reliable, contact resistance is less, substantially do not generate heat, long service life, thus guarantee that light shows the normal reliable work of testing circuit, improved the safe reliability of driving.
