Abstract
A key chain provided comprises a transparent holding case, a circuit board, an LCD panel, and a solar battery sheet. The holding case encloses the circuit board, the LCD panel, and the solar battery sheet, which form a closed circuit through an electrical property connection; the LCD panel can be seen by permeating a transparent plane of the holding case from the exterior of the holding case; the solar battery sheet can be seen by permeating another transparent plane of the holding case from the exterior of the holding case. The key chain enables external ray to irradiate on the solar battery sheet so that the control of the circuit board can make the LCD panel change its color and twinkle continuously in a certain area.
Description
Technical field
The utility model relates to a kind of key chain, relates in particular to a kind ofly to utilize the solar powered LCD of making and the plate changes colour does not stop the key chain that glimmers.
Background technology
Key chain is requisite articles for daily use in the middle of people live, basically be on very close terms with people, and present general key chain has only the effect of single string key, the function dullness, industry has designed a kind of key chain that has pattern, it comprises circuit board, LCD panel, the battery that electrically connects conducting, on the LCD panel, stick the pattern that is painted with scenery with hills and waters, calligraphy, personage etc., then they are enclosed in the lump in the transparent container, control the change color that can realize the LCD panel by circuit board and do not stop flicker.Above-mentioned key chain utilizes powered battery, will more renew battery after a while, consumes a large amount of batteries, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of key chain, and it utilizes the solar powered LCD of making panel changes colour not stop flicker.
For achieving the above object, the utility model provides a kind of key chain, it comprises a transparent container, one circuit board, an one LCD panel and a solar battery sheet, this container is with this circuit board, LCD and plate and solar battery sheet encapsulate, this circuit board, LCD and plate and solar battery sheet electrically connect into a closed circuit, can see this LCD panel from the outside transparent area that sees through this container of container, can see this solar battery sheet from outside another transparent area that sees through this container of container, light from outside can be shone on this solar battery sheet, and the control of this circuit board makes the LCD panel necessarily change color and not stop flicker in the zone during light irradiation solar battery sheet.
The utlity model has following beneficial effect: solar battery sheet utilizes the solar energy power supply of generating electricity in the utility model, replaces powered battery, makes this LCD panel can change color and does not stop flicker, has saved battery, has reduced cost.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the utility model key ring.
Fig. 2 is the side cross-sectional views of the utility model key ring.
The specific embodiment
See also Fig. 1 to Fig. 2, a kind of key chain, it comprises transparent container 2, a circuit board 3, a LCD panel 4 and the solar battery sheet 5 of key ring 1, of bunch of keys.
This container 2 is cuboids, and this circuit board 3 is installed on the bottom of this container 2, and this LCD panel 4 is installed on this circuit board 3, and this solar battery sheet 5 is installed on the side of this circuit board 3 and LCD panel 4.This container 2 gets up this circuit board 3, LCD panel 4 and solar battery sheet 5 encapsulation.
This circuit board 3, LCD panel 4 and solar battery sheet 5 electrically connect into a closed circuit, and solar cell can generate electricity when light from outside shone on this solar battery sheet 5.The both positive and negative polarity of solar battery sheet 5 connects the positive-negative input end of this circuit board 3 respectively, and the positive-negative output end of this circuit board 3 connects the both positive and negative polarity of this LCD panel 4 and forms closed circuit.The utility model can have multi-disc solar battery sheet or monocrystalline silicon, polysilicon, non-crystalline silicon, and non-crystalline silicon also can be epistasis or weak property simultaneously.
Can see this LCD panel 4 from container 2 outside transparent areas 22 that see through this container 2, can see this solar battery sheet 5 from outside another transparent areas 24 that see through this container 2 of container 2, light from outside can be shone on this solar battery sheet 5 and produce electric current.
In the utility model, utilize the solar energy power supply of generating electricity, replace powered battery, make this LCD panel 4 can change color and do not stop flicker, saved battery, reduced cost with solar battery sheet 5.
