Abstract
The utility model discloses the laser sighting device device on a kind of toy, be arranged in toy body, the motor being provided with circuit board in toy body and being controlled by circuit board, circuit board is by Power supply, the output circuit of described motor is in series with laser sighting device, the circuit between described motor and laser sighting device is in series with mu balanced circuit.Compared with prior art, the utility model is after electrical power, and current delivery on mu balanced circuit, and then transfers out burning voltage on laser sighting device by mu balanced circuit, so just can ensure that laser sighting device is not fragile.
Description
Technical field
The utility model relates to the laser sighting device device on the toy, particularly a kind of toy of band sight.
Background technology
At present, the sight that existing toy is installed, launches motor by remote pilot, and because voltage when stopping by electric motor starting connection to load outputting power and motor has larger fluctuation after electrical power, so unstable voltage can cause laser sighting device to damage.
Summary of the invention
The purpose of this utility model to provide the device of the laser sighting device on a kind of toy.
For achieving the above object, the utility model is implemented according to following technical scheme:
Laser sighting device device on a kind of toy, be arranged in toy body, the motor being provided with circuit board in toy body and being controlled by circuit board, circuit board is by Power supply, the output circuit of described motor is in series with laser sighting device, the circuit between described motor and laser sighting device is in series with mu balanced circuit.
Particularly, described mu balanced circuit comprises an a Zener diode ZD1 and transistor T1, described transistor T1 colelctor electrode is connected with the positive pole of DC rectifier circuit by a resistance R1, emitter stage is connected with the negative pole of DC rectifier circuit, base stage connects emitter stage after being connected by a resistance R2 and a resistance R3, the positive pole of Zener diode ZD1 is connected with the positive pole of DC rectifier circuit, the negative pole of Zener diode ZD1 is connected between resistance R2 and resistance R3, and described laser sighting device is in parallel with Zener diode ZD1 and R3 connected.
Preferably, on described circuit, be connected with remote signal receiver, be convenient to carry out remote control by long-range.
Compared with prior art, the utility model is after electrical power, and current delivery on mu balanced circuit, and then has mu balanced circuit to transfer out burning voltage on laser sighting device, so just can ensure that laser sighting device is not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of mu balanced circuit.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in the illustrative examples of this utility model and explanation, but not as to restriction of the present utility model.
Laser sighting device device on a kind of toy as shown in Figure 1, be arranged in toy body, the motor 4 being provided with circuit board 1 in toy body and being controlled by circuit board 1, circuit board 1 is powered by power supply 3, circuit is connected with remote signal receiver 2 on 1, the output circuit of motor 4 is in series with laser sighting device 6, the circuit between motor 4 and laser sighting device 6 is in series with mu balanced circuit 5.
Concrete, with reference to Fig. 2, mu balanced circuit 5 comprises an a Zener diode ZD1 and transistor T1, described transistor T1 colelctor electrode is connected with the positive pole of DC rectifier circuit by a resistance R1, emitter stage is connected with the negative pole of DC rectifier circuit, base stage connects emitter stage after being connected by a resistance R2 and a resistance R3, the positive pole of Zener diode ZD1 is connected with the positive pole of DC rectifier circuit, the negative pole of Zener diode ZD1 is connected between resistance R2 and resistance R3, and laser sighting device 6 is in parallel with Zener diode ZD1 and R3 connected.Voltage raises when the motor is activated, Zener diode ZD1 voltage-stabiliser tube reverse breakdown and conducting, the dividing potential drop of Zener diode ZD1 and R3 makes transistor T1 be in saturation conduction state after the current limliting of R2, the pressure drop of the collector and emitter of transistor T1 is very little, negligible, transistor T1 does not consume electric energy substantially, voltage is all applied on resistance R1, because resistance is power device, select dissimilar resistance R1 and transistor can consume the electric energy of relatively high power, as selected wire resistor or other high-power resistances, adopt High-power Semiconductor Triode, effectively can stablize the voltage on laser sighting device 6, prevent laser sighting device 6 from damaging.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
