Abstract
The utility model discloses a multifunctional and energy-saving alarm which is suitable for an automobile. The light and the acoustic alarm for overtaking acoustic alarming, turning, backing, low pressure, or low oil pressure of a tractor is a necessary device for a motor-driven vehicle to be arranged. The machine core of the multifunctional and energy-saving alarm comprises a transistor, an integrated block, and other small-sized components, sealed on the rear part in the outer case of a sounder which is a purpose-made and small-sized electric horn loudspeaker. Compared with the alarm device used in the technical field, the multifunctional and energy-saving alarm has the advantages of simple structure, one machine with multifunction, less power consumption, and low cost.
Description
Multifunction energy-saving letter Chinese percussion instrument is about self-propelled vehicle, particularly automobile overtake other vehicles blow a trumpet, turn, light that reversing, infrabar or low oil pressure are used, acoustic warning device, be safe driving must adorn utensil.
The prior art of this technical field, patent document DE3307476, the flashing feature of direction indicator for vehicle, use fixed frequency, different time width flashing signals, the travel direction of expression vehicle, the turning indicator signaling device of patent document FR2533179A on-road vehicle, this device is produced a well-regulated signal that regulates with one and will be overtaken other vehicles to show, another producer produces variable periodic signal and will turn to the left or to the right to show.More than two patents make signal with light, better in the night running effect, travel daytime easily and to be ignored by its car chaufeur and pedestrian.
The Electromagnetically vibrating loudspeaker that are used to overtake other vehicles and blow a trumpet that extensively adopt utilize the break-make of contact to inhale moving armature during its work at present, drive the diaphragm vibration and sound.Effect is better when dispatching from the factory, but uses after a period of time because of electric arc, makes the contact corrosion, and electric current diminishes and changes voice, and power consumption is bigger, if will adapt to the city and travel, satisfies the countryside again and overtakes other vehicles and blow a trumpet, then need to adorn two loudspeaker, promptly a snail type, a basin type can realize with switch change-over.A general automobiles is complete the assembling of the equipment of above-mentioned various warning functions, and not only expensive more, the installation and maintenance amount also increases.
The utility model can overcome above-mentioned deficiency, under the situation that does not change former fare road, multifunction energy-saving letter Chinese percussion instrument, just can realize easily overtaking other vehicles blow a trumpet, turn, the light and the audible alarm of reversing, infrabar and low oil pressure.
Solution of the present utility model is: multifunction energy-saving letter Chinese percussion instrument is made up of clock oscillator, audio frequency oscillator, power amplifier, rattler (being loudspeaker) and functional mapping relay, rattler is a purpose made small electrical dynamic formula horn speaker, the movement of being made up of components and parts such as oscillator, amplifirer and relays is encapsulated in the rear portion in the rattler shell, or with the rattler separate package.
Figure one and figure two are embodiment of the present utility model.
Figure one is a multifunction energy-saving letter Chinese percussion instrument constructional drawing.
Figure two is multifunction energy-saving letter Chinese percussion instrument schematic diagrams.
1 is rattler among the figure, the 2nd, and movement, the 3rd, shell, the 4th, support, the 5th, clock oscillator, it produces the well-regulated periodic signal that the certain hour width is arranged, and removes to control the flash of light and the sound of turning.The two hockets its flash of light and the sound.The 6th, audio frequency oscillator, by change-over switch and relay, match, regulate the resistance of resistance 9,10,11, can obtain the sound signal of four kinds of setting, the 7th, audio-frequency power amplifier, the 8,9, the 10th, load, the 10th, dropping resistor, 8,9,10 all is load when promptly turning, when blowing a trumpet the 8, the 9th, and load, the 10th, dropping resistor.Match, adjust three's the ratio and the operation point of power amplifier, can obtain three kinds of different volumes outputs, its size is within standard.
When turning switch 17 was incorporated into position A or B, electric current made clock oscillator 5 through isolation diode 20,21,22, audio frequency oscillator 6, and power amplifier 7 work, loud speaker 8 sends the sound.When the open contact of relay 12 was closed, Cornering Lamp 26 or 27 was luminous, and the sound stops simultaneously.The load of clock oscillator is alternately sent the sound and flashing signal.
When chaufeur is pressed button 24, open contact 13 closures of relay 13, electric current is through diode 19, resistance 9,10, power amplifier 7, audio frequency oscillator 6 makes loud speaker send the sound of blowing a trumpet.Volume change-over switch 25 is applicable to that the city travels when a position, when the b position, be applicable to that the countryside travels.
When air pressure that is used to brake or oil pressure, or when being used for the engine lubrication engine oil pressure and being lower than standard value, sensor 18 or 18 ' the make open contact 14 ' closure of relay 14, electric current is through diode 23, resistance 11, make audio frequency oscillator 6, power amplifier 7 work, loud speaker 8 sends continuously chimes of doom and red indicator signal, and alerting driver is noted and can not be driven.
According to purposes, the flashing rate of this letter Chinese percussion instrument, sound frequency, volume etc. all can be adjusted within the standard, its volume is little, cost is low, little power consumption, and maximum power consumption is the 1/12-1/3 of general electric automobile horn only, general vehicle, do not change former fare Lu Douke and install, not only save flasher, electric horn, but also increase usefulness.
Claims (1)
1, multifunction energy-saving letter Chinese percussion instrument is that a kind of letter that is used for motor vehicle safe drive rings warning device.It is characterized in that it forms by clock oscillator, audio frequency oscillator, power amplifier, rattler and with the components and parts 8,9,10,11,12,13,14,20,21,22,23 that function changes syntagmatic.
