Abstract
The utility model relates to an adjustable luminous intensity electric torch which can be attached on a car and is connected with a battery of the car. The utility model is characterized in that a magnet is inlaid at the lower end of the existing electric torch, and an output voltage regulation circuit and a rechargeable battery are added. The utility model can be conveniently applicable to emergency repair of cars.
Description
The utility model relates to the lighting device that a kind of motor vehicle repair is used, and especially can be adsorbed on the position of automobile needs and can regulate the flashlight of light intensity simply.
At present, known flashlight is made up of torch, battery, and its luminosity is constant.When as motor vehicle repair, need a hand-held torch, a hand operated, very inconvenient.
The purpose of this utility model provides a kind of torch, and the power supply that it can not only utilize automobile storage battery to make torch is adjusted the illumination intensity of torch, and can be adsorbed on the position that automobile needs easily.
The purpose of this utility model is achieved in that in the lower end of torch inlays a magnet, and torch be can be adsorbed on the automobile, and the optically focused part of torch can be rotated up and down, not only can shine the position that needs illumination but also do not need the people hand-held.Intensity variations relies on the adjusting of potentiometer to make the transistor base voltage change, causes that emitter voltage changes, and the luminous intensity of torch changes thereupon.This voltage can be given the charging of the rechargeable battery in the torch.Rechargeable battery in the torch is used in works as the illumination place away from automobile, when the torch cable falls short of, and use the same with common torch.If do not need this function, the battery in the torch can omit.
Owing to adopt such scheme, can be placed on the place that automobile need throw light on and need not hand, also can regulate light intensity.Have simultaneously and common torch identical functions.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the vertical section structural map of first embodiment of torch.
Fig. 3 is I-I cutaway view of Fig. 2.
Among the figure 1, automobile storage battery, 2, fuse, 3, torch switch, 4, resistance, 5, potentiometer, 6, resistance, 7, triode, 8, resistance, 9, resistance, 10, diode, 11, charge switch, 12, discharge and recharge indicator lamp, 13, rechargeable battery, 14, torch bulb, 15, magnet, 16, feed cable, 17, connector assembly, 18, printed circuit board (PCB).
In Fig. 1, automobile storage battery (1), fuse (2), torch switch (3) links, and behind the switch closure, transistor base voltage is by resistance (4) 7.5K, potentiometer (5) 1K, resistance (6) 3.6K decision, when the potentiometer resistance to earth increased, base voltage raise, transistor emitter voltage also increases, the torch luminous intensity increases, otherwise then brightness reduces.Diode (10) shields.Resistance (8) 10 Ω are current-limiting resistance, and resistance (9) 10K is for emitter stage provides loop current.Illumination time is to the torch battery charge, and it is bright to discharge and recharge indicator lamp (12), and switch (11) disconnects illumination when opening, charge the battery separately.
In embodiment illustrated in fig. 2, the cable (16) by automobile storage battery (1) joins with the connector assembly (17) of torch, and torch switch (3) is placed on the torch side, with potentiometer (5) be one, switch is upwards stirred and is closure, upwards promotes again, dividing potential drop increases, and torch brightness is increased.Charge switch (11) is placed on the torch switch (3), and the upper end all is welded in (18) on the printed circuit board for discharging and recharging indicator lamp (12) resistance, diode, fuse, and magnet is fixed on torch bottom, and can be adsorbed on automobile need illumination place.
Claims (1)
1, a kind of flashlight, by the torch shell, feed cable, fuse, switch, power adjustment circuit, rechargeable battery, bulb constitute, and it is characterized in that: a magnet is inlayed in torch shell lower end, and feed cable one end connects automobile storage battery, the other end connects the power input of the power adjustment circuit in the torch, connect, disconnect by switch control, the output of power adjustment circuit divides two-way, one the tunnel receives the rechargeable battery in the torch, and another road connects the torch lighting bulb by switch.
