[0020] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-Figure 3 As shown, the utility model provides an outdoor power supply with TV and game console functions, including a charging module, an electric energy conversion module and an output module. The electric energy conversion module includes an energy storage component and an electric energy inverter component. The charging module is connected to the energy storage component, the energy storage component is connected to the electric energy inverter component, and the electric energy inverter component is connected to the voltage stabilizing output component.

[0023] The electric energy output by the AC charging component and the photovoltaic charging component is transmitted to the electric energy conversion module through the charging module, and the output electric energy is temporarily stored by the energy storage component. The DC power output by the energy storage component is boosted and inverted by the power inverter component and converted into AC power. The AC power output by the power inverter component is transmitted to the voltage-stabilizing output component, and the voltage-stabilizing output component rectifies the AC power and converts it into stabilized DC power.

[0024] Principle: The charging module transmits electrical energy to the energy storage component for temporary storage through the AC charging component and the photovoltaic charging component. The current output by the energy storage component is converted by the power inverter component and the voltage stabilizing output component, thereby providing a stable constant voltage DC power for the LCD TV to ensure the normal operation of the LCD TV.

[0025] In order to boost the current output by the energy storage component and reduce the power loss in the inverter circuit, the power inverter component includes a boost circuit and an inverter circuit connected to the boost circuit, wherein the boost circuit includes a transistor Q1 and a diode D1.

[0026] The collector of transistor Q1 is connected to the anode of diode D1 and inductor L1, inductor L1 is connected to capacitor C1, the cathode of diode D1 is connected to capacitor C2 and resistor R1, resistor R1 is connected to the other end of capacitor C2, the emitter of transistor Q1 and capacitors C1 and C2.

[0027] This circuit is a typical Boost circuit. When transistor Q1 is turned on, the input voltage is charged through inductor L1, and the current of inductor L1 increases linearly. Inductor L1 stores energy. At this time, capacitor C1 supplies power to resistor R1 to maintain a constant output voltage. When transistor Q1 is turned off, inductor L1 releases energy, generating a high-voltage pulse, which charges capacitor C2 through diode D1 and provides energy to resistor R1. At this time, the current of inductor L1 decreases, and the voltage polarity across inductor L1 is opposite, that is, negative on the left and positive on the right. The output voltage is higher than the input voltage, thus achieving a boost.

[0028] In order to convert the direct current output by the energy storage component into alternating current, the inverter circuit adopts a unidirectional full-bridge inverter circuit, wherein the inverter circuit includes transistor VT1, transistor VT2, transistor VT3, transistor VT4 and transformer T1.

[0029] One end of the main winding of the transformer T1 is connected to the emitter of the transistor VT1 and the collector of the transistor VT2, the other end of the main winding of the transformer T1 is connected to the emitter of the transistor VT3 and the collector of the transistor VT4, the secondary winding of the transformer T1 is connected to the inductor L2, the other end of the inductor L2 is connected to the capacitor C3 and the resistor R2, the other end of the secondary winding of the transformer T1 is connected to the other end of C3 and the other end of R2.

[0030] In this circuit, when transistor VT1 and transistor VT4 are turned on and transistor VT2 and transistor VT3 are closed, the output voltage is the same as the input voltage. When transistor VT2 and transistor VT3 are turned on and transistor VT1 and transistor VT4 are closed, the output voltage is opposite to the input voltage. When they are turned on and off in turn, the conversion from DC to AC is realized.

[0031] In order to convert the AC power output by the inverter circuit into stable DC power, the voltage-stabilized output component includes a constant-voltage rectifier circuit, wherein the constant-voltage rectifier circuit includes a transformer T2 and a rectifier bridge BG connected to the secondary winding of the transformer T2.

[0032] The main winding of the transformer T2 is connected to the inverter circuit, one end of the rectifier bridge BG is connected to the resistor R3 and the capacitor C4, the other end of the rectifier bridge BG is connected to the positive electrode of the Zener diode VD, the capacitor C4 and the other end of the capacitor C5, and the resistor R3 is connected to the negative electrode of the Zener diode VD and the other end of the capacitor C5.

[0033] This circuit converts AC into pulsating DC through the rectifier bridge BG, and smoothes and filters it through capacitors C4 and C5, and then uses the voltage regulator diode VD to output constant voltage DC.

[0034] The charging module includes a mains charging component and a photovoltaic charging component. The mains charging component is connected to the energy storage component accordingly, and the photovoltaic charging component is connected to the energy storage component accordingly. The mains charging component and the photovoltaic charging component use two different methods to transmit electricity to the energy storage component.

[0035] The voltage-stabilized output component of the output module delivers stable current to the LCD TV. The LCD TV and the handle are connected using an HDMI interface to ensure smooth operation of the LCD TV's gaming functions. The LCD TV has headphone and audio interfaces.

[0036] When in use, the outdoor power supply with television and game console functions is charged at home by a mains charging component, and is charged outdoors by a photovoltaic charging component using solar energy, ensuring that the outdoor power supply stores sufficient electrical energy. The electrical energy output by the mains charging component and the photovoltaic charging component is transmitted to the electrical energy conversion module via the charging module, and the output electrical energy is temporarily stored by the energy storage component. When the television and game functions of the outdoor power supply are used, the direct current output by the energy storage component is boosted and inverted by the electrical energy inverter component to be converted into alternating current. The alternating current output by the electrical energy inverter component is transmitted to the voltage-stabilizing output component, which rectifies the alternating current and converts it into voltage-stabilized direct current, thereby providing stable constant-voltage direct current for the LCD television, ensuring normal use of the LCD television and game console functions.
