Technical Field

[0002] Chinese patent publication number CN202364359U, "A Packaging Box," provides a technical solution for installing a display device on the surface of the box. The display device includes a liquid crystal display, a circuit board, and a power supply. However, since the LCD screen is relatively power-hungry, a screen switch button is used to completely turn off the power when the screen is not needed, and a solar cell automatically charges the rechargeable battery when there is light. This allows for long-term playback in a showroom, at home, or anywhere with light. However, as we know, solar cells alone are not enough to power the LCD screen, and rechargeable batteries themselves are not environmentally friendly. Summary of the Invention
[0003] The photokinetic energy cell described in this document is a type of photovoltaic cell, which is a photovoltaic conversion device that uses semiconductor thin film material as the photoelectric conversion layer and has photoelectric conversion function and DC power output.
[0004] In order to solve the problem of recycling and pollution caused by the need to use chemical batteries due to insufficient power supply to the liquid crystal display, the purpose of the utility model is to invent a packaging box that uses a photodynamic processor to drive the liquid crystal light valve for dynamic display. The liquid crystal light valve is used to dynamically display the background pattern. The liquid crystal light valve is directly driven by the photodynamic processor, and there is no need to install chemical batteries, thereby reducing pollution. The specific technical solution is: a packaging box that uses a photodynamic processor to drive the liquid crystal light valve for dynamic display, characterized in that: the packaging box includes a box body and a box cover, a liquid crystal light valve and a photodynamic processor are installed in the hollow part of the box cover, and a picture or a picture changing device with a picture is placed under the liquid crystal light valve; the photodynamic processor is a control circuit module composed of a power management chip, a socket and other electronic components after the circuit is made on the backlight surface of the photodynamic battery with glass or polymer material as the substrate. The photodynamic processor connects the power output by the photodynamic battery to the liquid crystal light valve through the socket, opens or closes the liquid crystal light valve, so that the picture under the liquid crystal light valve is dynamically displayed.
[0005] The box cover includes an outer skin, an inner lining and a gasket. The hollow part of the outer skin corresponding to the thin-film photovoltaic cell can be arc-shaped, rectangular or other shapes. The outer skin and the inner lining are unfolded and bonded together and then folded to form the top and sides of the box cover. The bottom opening is buckled on the box body. The liquid crystal light valve and the light kinetic energy processor are placed between the outer skin and the inner lining, located on the top of the box cover. The gasket is bonded to the inside of the inner lining. The gasket accommodates the power management chip, socket and other electronic components on the picture changing device and the light kinetic energy processor.
[0006] The liquid crystal light valve is located in the middle position, and there are two light kinetic energy processors connected in parallel, located on both sides of the liquid crystal light valve. The light-receiving surfaces of the liquid crystal light valve and the kinetic energy battery are covered with a transparent thin plate of polymer material, such as organic glass (PMMA).
[0007] The picture changing device has the following three structures, which can change pictures automatically or manually: the first structure is a detachable plug-in cover type picture changing device, the plug-in cover is provided with pins, plugs and picture slots, the pins are inserted into the side holes corresponding to the gaskets, the plugs are provided with elastic expansion openings, the plugs are inserted into the vertical holes corresponding to the gaskets, the elastic expansion holes are opened to press the plugs tightly against the vertical hole walls, the picture slots have four sides that are consistent with the size of the picture, the long sides are slots, the short sides are baffles, the picture is inserted in the slot, and the plug-in cover can be removed to change the picture.
[0008] The second structure is a conveyor belt type manual picture changing device, which includes a conveyor belt mechanism consisting of a driving wheel, a driven wheel and a belt. The belt is installed on the driving wheel and the driven wheel. The picture is attached to the belt. A manual dial wheel is installed on the driving wheel. The manual dial wheel is exposed from the top of the box cover. The manual dial wheel is turned to drive the driving wheel to rotate, so that the picture moves on the belt.
[0009] The third structure is a conveyor-type automatic picture changing device, which includes a conveyor belt mechanism consisting of a driving wheel, a driven wheel and a belt. A DC motor is installed on the driving wheel. The DC motor drives the driving wheel to rotate, so that the picture moves on the belt. The DC motor is powered by the light kinetic energy processor to the energy storage capacitor and controls the picture stop position and / or stop time.
[0010] The outer skin and inner lining are made of paper material or polymer film material. The outer skin is thinner with a thickness of 0.3mm to 0.8mm, and the inner lining is thicker with a thickness of 1.5mm to 3mm.
[0011] The gasket is made of ethylene-vinyl acetate copolymer and is provided with grooves for convenient placement of the picture changing device and the wiring of the light kinetic energy processor.
[0012] The control circuit module includes a light valve control circuit module and a motor control circuit module.

The light energy battery outputs to the energy storage capacitor through the three-terminal voltage regulator of the voltage stabilizing circuit. The energy storage capacitor supplies power to the MCU control chip, which is awakened by the photoresistor signal. The MCU control chip controls the H-bridge circuit to control the forward or reverse rotation of the motor, as well as the position and time of the picture stop.
[0013] When the image changing device is a conveyor-type automatic image changing device, the control circuit module is divided into two paths. One path directly uses a voltage regulator to step down and stabilize the input voltage of the solar battery to the switching voltage of the liquid crystal light valve; the other path first uses a voltage regulator to step down and stabilize the input voltage of the solar battery to the voltage of the energy storage capacitor. The charge and discharge circuit compares the threshold value of the hysteresis comparator with the charging voltage of the charging capacitor. When it is higher than the high threshold value of the hysteresis comparator, the energy storage capacitor is discharged. When it is lower than the high threshold value of the hysteresis comparator, the energy storage capacitor is charged.
[0014] When the image changing device is a detachable plug-in type image changing device or a conveyor type manual image changing device, the control circuit module does not require an energy storage capacitor, and the step-down and voltage stabilization circuit can step down and stabilize the input voltage of the solar cell to the switching voltage of the liquid crystal light valve by a voltage regulator tube.
[0015] The positive and beneficial effects of the present invention are as follows: First, since a liquid crystal light valve is used to display images, the power output by the photovoltaic cell can fully meet the needs of the liquid crystal light valve, so there is no need for chemical battery energy storage, which is environmentally friendly and energy-saving.
[0016] Second: You can replace the picture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0030] The packaging box has a lid and a box body 2, and the lid includes an outer skin 1, an inner lining 2 and a gasket 3. There are two solar energy processors 5, among which the photovoltaic cell 501 has an open circuit voltage of 7V and an operating voltage of 5V. A socket 504 is bound to the backlight surface of one solar energy cell 501, and a power management chip 502, a storage capacitor 503, a socket 504 and other electronic components 505 are bound to the backlight surface of the other solar energy cell 501. The two solar energy cells 501 are connected in parallel through the socket 504, and then the solar energy processor 5 is connected to the liquid crystal light valve 6 through the socket 504. A picture 7 is pasted on the back of the liquid crystal light valve 6. The switch of the liquid crystal light valve 6 is driven by the solar energy processor 5 to flash the picture 7.
[0031] The outer shell 1 and inner lining 2 are made of paper. When laid out flat, a liquid crystal light valve window 102 is machined in the center of the upper portion of the outer shell 1 to display the image 7 below the liquid crystal light valve 6. Solar cell windows 101 are machined on either side of the liquid crystal light valve window 102, allowing the solar cell 501 to absorb light. The inner lining 2 is provided with a transparent plate placement step 203, a light function processor installation window 201, and a liquid crystal light valve installation window 202. A transparent sheet 4 is placed on the transparent plate placement step 203 to shield and protect the solar cell 501 and liquid crystal light valve 6. The outer shell 1 and inner lining 2 are bonded together, and the solar processor 5 and liquid crystal light valve 6 are then placed in their corresponding light function processor installation windows 201 and liquid crystal light valve installation windows 202.
[0032] The gasket 3 is made of ethylene-vinyl acetate copolymer (EVA), and is provided with a light energy processor accommodating hole 301 and a liquid crystal light valve placement step 302 that are interconnected. The size of the light energy processor accommodating hole 301 is smaller than the light energy battery 501, so it can be placed in the light function processor installation window 201 to prevent it from falling. The power management chip 502, energy storage capacitor 503, socket 504 and other electronic components 505 on the light energy processor 5 are accommodated in the light energy processor accommodating hole 301, and the wiring is arranged in the through groove. Since the liquid crystal light valve 6 is thicker than the light energy battery 501, a liquid crystal light valve placement step 302 of the same size as the liquid crystal light valve 6 is provided at the gasket position to accommodate the thickness of the liquid crystal light valve 6 exceeding the liquid crystal light valve installation window 202. The gasket 3 is bonded to the corresponding position of the lining 2, and then the outer skin 1 and the lining 2 are folded into the upper cover.

The manual picture changing device 9 mainly includes a driving wheel 901, a belt 902, a bearing 903, a manual dial wheel 904 and a driven wheel 905. The bearing 903 is installed on the gasket 3.

Bearings 903 are installed at both ends of the driving wheel 901 and the driven wheel 905 and placed on the gasket 3. Corresponding to the protruding position of the manual dial wheel 904, holes are opened on the outer skin 1 and the inner lining 2 to expose the edge of the manual dial wheel 904. When the edge of the manual dial wheel 904 is turned, the driving wheel 901 and the driven wheel 905 drive the belt 902 to move, and the leaves of the picture 7 on the belt 902 move accordingly, thereby realizing the replacement of the picture 7.

[0038] Compared with Example 2, Example 3 installs a rotating DC motor 906 at one end of the driving wheel 901, and the manual dial wheel 904 can be retained or not used. The rotating motor 906 is connected to the light kinetic energy processor 5, powered by the energy storage capacitor 503, and its rotation position and residence time are controlled by the power management chip 502. Each time the entire picture 7 moves, it falls exactly under the liquid crystal light valve 6, stays for a few seconds, and then moves again, constantly changing the picture 7.
[0039] Circuit diagram as follows Figure 12 As shown, the output J2 of the solar cell 501 is connected to the input J1 of the liquid crystal light valve 6 through the comparator circuit composed of R2, R4, R3, R5, C3, and U2, controlling the opening or closing of the liquid crystal light valve 6. R2 is a sampling current-limiting resistor, R3 and R4 are voltage-divider resistors, C3 and R5 are used by the comparator U2 to adjust the charge and discharge oscillation frequency, and R7 is a current-limiting resistor for the liquid crystal light valve. The output end of the solar-powered battery 501 is connected to the input end J4 of the rechargeable battery or energy storage capacitor 503 for charging through the voltage-stabilizing circuit output composed of C2, a three-terminal voltage-stabilizing tube U1, and C1. The VCC output end of the rechargeable battery or energy storage capacitor 503 is connected to the VDD pin of the timing rotation MCU chip U3. The VCC output end of the rechargeable battery or energy storage capacitor 503 is connected to the ADC0 pin of U3 through the voltage-dividing resistor R6, the photoresistor R7, and the filter capacitor C5. The ADC1 and PWM2 output control signals of U3 are connected to the IN1 and IN2 pins of U4. An H-bridge circuit is formed by U4, C6, and C7. The ADC1 of U3 is connected to the IN1 of U4, and the PWM2 of U3 is connected to the IN2 of U4. The OUT1 of U4 is output to the OZ of the motor input terminal J3, and the OUT2 of U4 is output to the OF of the motor input terminal J3. The H-bridge circuit controlled by the MCU can realize the forward rotation, reverse rotation, and stop position of the motor.
