Abstract
The utility model relates to a monitor for the lamps of motor vehicles such as a motor car, etc., comprising a normal-open contact point, a thread ring, a casing and an indicating lamp. The utility model which has small size has the advantages that the utility model can be installed in a driving room without the change of the original circuit of the motor car, a driver can learn about the working conditions of the lamps, such as the braking lamp or the directional lamp of the motor car, etc.
Description
The utility model is a kind of improvement to self-propelled vehicle, particularly about a kind of brake lamp of self-propelled vehiclees such as automobile and device of indicator electronic monitor of being used for.
For safety, self-propelled vehiclees such as automobile all are equipped with brake lamp and indicator (general designation car light) at vehicle tail end, but up to the present, operator's compartment does not have the automotive lamp monitor.Chaufeur will check whether Vehicular lamp normal, and work is inconvenience very, especially self-propelled vehicle in the process of moving, because of a variety of causes causes the unexpected damage of automotive lamp, chaufeur can not be realized.If brake lamp damages, when chaufeur was taked braking maneuver, brake lamp did not work, not only chaufeur can not in time be known, and can not provide information to the vehicle of following later, and is particularly crowded at city vehicle, the pedestrian continues to drive in various street, and this is a danger close, causes the accident easily.Therefore the police personnel are also very heavy to the chaufeur punishment that automobile brake lamp damages, so chaufeur all wishes at operator's compartment the automotive lamp monitor to be housed.
For this reason, the purpose of this utility model just provides a kind of automotive lamp monitor that is installed in operator's compartment, so that chaufeur is understood the service condition of automotive lamp at any time, improves the safety of motor-driven vehicle going.
The utility model Vehicular lamp monitor, constitute by the dry-reed tube with open contact, coil, shell and indicator lamp, said coil is on dry-reed tube, the pig-tail wire of one end of winding wire and the dry-reed tube one reed formation input end that links, the other end of winding wire is a mouth, and another reed pig-tail wire of dry-reed tube connects indicator lamp.Said coil and dry-reed tube are enclosed in the shell.
Principle of work of the present utility model is to utilize the automotive lamp power supply by the magnetic field that coil produces, make dry-reed tube work, moment work or do not work, by the bright, glittering of indicator lamp and do not work judge automotive lamp be good entirely, one lamp is bad or two lamps are all bad.
The utility model has the advantages that:
1. this device volume is little, can directly be connected in the circuit of automotive lamp, and indicator lamp can be installed in
The operator's compartment appropriate location, the room of gauge panel for example needn't change the primary circuit of self-propelled vehicle.
2. chaufeur is not only before going out car but also all can understand the work shape of Vehicular lamp at any time at road
Condition, the discovery lamp has been broken and can have been changed immediately.
3. low price is easy for installation.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is a utility model Vehicular lamp monitor structure principle chart.
Fig. 2 is utility model Vehicular lamp monitor embodiment---the electrical schematic diagram that the automobile brake lamp monitor is installed.
Among Fig. 1,1 for having the dry-reed tube of open contact, 2-coil, 3-shell, 4-indicator lamp, coil 2 is on dry-reed tube 1, an one reed pig-tail wire of dry-reed tube 1 and an end of coil 2 leads link and form input end 6, the other end of coil 2 leads is a mouth 5, and the pig-tail wire of another reed of dry-reed tube 1 connects indicator lamp 4, and this has just constituted the Vehicular lamp monitor.Coil 2 and dry-reed tube 1 are enclosed among the shell 3.
The installation of automobile brake car light monitor as shown in Figure 2.The existing automobile brake lamp 7 and 8 that connects bonding (being ground connection) directly is connected in an end of the brake switch of often opening 9, another termination+12 volt power supply of switch 9.During installation, switch and brake lamp circuit are disconnected, the automobile brake lamp monitor is connected in switch 9 and the brake lamp circuit, the input end 6 that is the automobile brake lamp monitor connects brake switch 9, mouth 5 connects brake lamp 7 and 8, indicator lamp 4 is installed in bridge instrumentation dish or other appropriate locations, indicator lamp 4 free termination bonding (being ground connection).When chaufeur pedal brake pedal, brake switch 9 closures, electric current promptly forms the loop through coil 2, brake lamp 7 and 8 to bonding, when lamp 7 and 8 complete when good, by the power supply of every lamp about 1.7 amperes, 3.4 amperes of the total currents of two lamps, the electromagnetic field that this electric current produces by coil 2 is enough to contact adhesive that dry-reed tube is often opened, thereby electric current passes through this dry-reed tube and indicator lamp 4 forms the loop to bonding, and indicator lamp 4 is bright.When pin was not stepped on plate, brake switch 9 disconnected, and indicator lamp 4 and brake lamp 7 and 8 extinguish simultaneously.If a brake lamp is bad, then when stop lamp switch is closed, owing to pass through the magnetic field that the instantaneous current of coil 2 produces, equally can be the instantaneous adhesive of reed switch contact, indicator lamp is bright, but when brake switch after the closed a certain short time, because only 1.7 amperes of the power supplys of a brake lamp, at this moment the electric current by coil 2 only is 1.7 amperes, the number of turns setting of coil, just in time make it reed that current field that the electric current by coil produces can not make dry-reed tube again adhesive disconnect, therefore, do not have electric current to pass through indicator lamp 4 again, indicator lamp 4 extinguishes.Therefore indicator lamp 4 presents glittering.When two brake lamies damaged, even the stop lamp switch closure, the brake lamp loop did not all have electric current, and coil 2 does not have electric current to pass through, the impossible adhesive of the open contact of dry-reed tube 1, and the loop does not have electric current, and therefore, indicator lamp 4 does not work.Like this, bright, glittering and do not work during chaufeur pedal brake pedal by indicator lamp 4, can judge that brake lamp 7 and 8 is good entirely, an evil idea or bad entirely.
Adopt JAG-4H dry-reed tube open in usual, with enamel wire spool 10-13 circles, voltage is 12 volts of indicator lamps, and the automobile brake lamp monitor of formation proves that by experiment the utility model is successful.Said indicator lamp 4 also can adopt the crystal lamp or the crystal lamp group of serial connection one resistance to make, and also can finish function of the present utility model.
