Abstract
The utility model discloses a flash automobile braking lamp capable of reflecting braking strength. The utility model is an automotive braking signal generation device which is used to prompt a driver of back vehicle to know the braking state of the front vehicle. The utility model comprises binding posts 1, 7 and a switch outer shell 2. A sealing ring 5, a membrane 4 and a pressure sensor are installed at the lower part of the outer shell 2, a sensor 6 is connected with an amplifying oscillation switch circuit board 3 by a conducting wire, and the circuit board 3 is connected with the binding posts 1, 7. When the flash automobile braking lamp capable of reflecting braking strength is used, the lighting of lamp bulb adopts the flicker mode when the vehicle braking happens, and the flickering frequency is increased by the increasing of the braking intensity. While in use, the braking situation of the front vehicle can be judged simply and expeditiously, and the back vehicle can take the relevant method as soon as possible; thus, the endurance strength of the driver can be lightened, and the accident can be reduced.
Description
The utility model belongs to automotive meter instruments and meters manufacturing field and is installed in indoor existing 12V of automobile or the 24V storage battery of utilizing of vehicle drive and is power supply, by op amp or differential amplifier and resistance, components and parts such as light-emitting diode monitor on the automobile various signal marking lamps and circuit whether intact, and the condition of service of shows signal marker lamp, can be widely used on the various automobiles, for traffic safety provides safeguard.
The existing various signs of automobile do not have fault display device, various marker lamps (steering indicating light, stoplight stop lamp, backing-up lamp, registration mark light, position lamp, flank indicator etc.) whether check to dress lamp place by normal need, if having the assistant just need get on or off the bus, the driver do not check back and forth, comparatively bother, phenomenons such as electric leakage or short circuit appear as marker lamp damage when driving or marker lamp circuit, the driver is in operator's compartment and do not know, is easy to take place traffic accident, and may damages the electric power system on the car.
The purpose of this utility model is to eliminate above-mentioned shortcoming, utilizes existing 12V or 24V power supply on the automobile, and when which marker lamp the driver used, corresponding with it demonstration light-emitting diode was just luminous on the car bulb telltale, and expression is normal.If marker lamp has one or more damages then shows that light-emitting diode extinguishes on this road, and sends chimes of doom, as this road circuit electric leakage or short circuit, then cooresponding with it overload lumination of light emitting diode take place.Because car bulb fault telltale is contained in the operator's compartment, so the driver just can know very clearly that in operator's compartment which light and circuit have fault, is convenient to timely eliminating, eliminate accident potential, guarantee traffic safety.
Fig. 1 is the schematic circuit diagram of car bulb fault telltale.
Its principle of the utility model embodiment (Fig. 1 shows) is that to utilize original 12V of automobile or 24V storage battery (1) be power supply, at turn signal swich (11) braking signal switch (4), the little light switch of back-up lamp switch (5) (7), seal in cooresponding with it lead or resistor wire (3) in the car bulb fault telltale respectively in the lighting circuit of flank indicator switch (6) back, when opening which marker lamp, electric current produces very little loss in voltage by resistance very little on lead or the resistor wire (3), lead this moment (3) just in time is lower than (22) some current potential in the adjustable resistance networking with the current potential of marker lamp junction (23), and be higher than (21) some current potential in the adjustable resistance net network, this moment op amp or differential amplifier (20), (18) output is in high level and low level respectively, show that light-emitting diode (17) is luminous this moment, represent that this road marker lamp is normal, marker lamp has damage or circuit that when opening circuit is arranged on this road, the current ratio normal value reduces on the loop, lead or resistor wire (3) are gone up loss in voltage and are reduced, (22) the some current potential is higher than (23) some current potential, the output of op amp or differential amplifier (18) changes high level into by low level, show that light-emitting diode (17) extinguishes, (2) some current potential is higher than the conducting of the anodal current potential warning circuit of storage battery (1) simultaneously, produces alerting signal.When the bulb of this road marker lamp or circuit are short-circuited or leak electricity, because the current ratio normal value increases in the loop, lead or resistor wire (3) are gone up pressure drop and are increased, to making (21) some current potential be higher than (23) some current potential, the output of op amp or differential amplifier (20) changes low level into by high level, overload light-emitting diode (19) is luminous, the expression overload.In driving when the steering indicating light et out of order, so fault go out in front still side or back to driver's disposition highly significant the utility model utilize op amp or differential amplifier (8) that the front directional of steering indicating light is monitored, provide demonstration by light-emitting diode (9).Lead or resistor wire (10) are connected in the front directional lamp loop, and its two ends are connected with the positive and negative input end of differential amplifier exclusive disjunction amplifier (8) respectively by resistor.When using, front directional flows through lead or resistor wire (10) produces pressure drop owing to electric current, thereby change the output state of op amp or differential amplifier (8), thereby turn to the light on and off of light-emitting diode (9) corresponding one by one before reaching with the light on and off of front directional.The power supply of op amp or differential amplifier (8), (18), (20) is by aerotron (15), (16), electric capacity (13), (14), the vibration insulating power supply power supply that voltage transformer (12) etc. are formed.Be higher than storage battery (1) voltage or guarantee the normal operation of op amp or differential amplifier by this with the power supply of storage battery (1) voltage isolation.
The utility model can be monitored the different types of car bulb of multichannel or other consumer, and is easy to use and reliable.
