Description

A kind of illuminating key

Technical field

The utility model relates to a kind of daily living article, is specifically related to a kind of illuminating key.

Background technology

Key is a kind of unlocking tool for opening door, cupboard, chest etc. during people live, and is a kind of conventional life instrument.What be used in combination with key is lockhole on tapered end, needs key alignment keyhole to insert and could open during use.And keyhole is generally smaller, needing when slotting key unlocking could quickly unlocking by certain light illumination.Therefore daytime or indoor have and to unblank when illumination to be a very simple thing, and night, when particularly not having street lamp at home, usually can not find the keyhole on door, and waste for a long time, extremely inconvenient.

For solving this technical problem, there is the key with illumination functions in the market, the Chinese utility model patent being CN202152567U as Authorization Notice No. discloses a kind of illuminating key, it is made up of lighting device and key, lighting device is made up of button cell, microswitch, light emitting diode, plastic sheath, button cell is connected with light emitting diode by microswitch, and button cell is placed in plastic sheath by the circuit that microswitch and light emitting diode are composed in series, lighting device is pasted onto key composition by seccotine.There is illumination functions, but it is the power supply using disposable button cell as light emitting diode, needs to change battery, be unfavorable for environmental protection, and its brightness of illumination is limited, there is certain limitation in use.

Utility model content

For above-mentioned deficiency, technical problem to be solved in the utility model is to provide a kind of illuminating key, illumination when unblanking night can be provided, be convenient for people to find keyhole to unblank fast at the night of dark, have that easy to use, brightness is large, energy-conserving and environment-protective advantage.

For solving the problem, the utility model is achieved through the following technical solutions:

A kind of illuminating key, comprise integrated key bit and the shank of the key, the surface of described the shank of the key is provided with lighting device, described lighting device comprises switch and can carry out the button cell group of recharging use, described lighting device also comprises solar panel, solar control circuit and two are electrically connected on the LED of button cell group output, described LED is located at the top of the shank of the key, described solar panel is electrically connected with the input of solar control circuit, the output of described solar control circuit is electrically connected with the input of button cell group, described switch is in order to control the keying of LED, and be located at the bottom of the shank of the key, described button cell group is connected in series by 2 button cells and forms.

In such scheme; described solar control circuit comprises central controller and the conversion and control module, transforming circuit, the charge controller that are all connected with central controller; the input of described conversion and control module is connected with solar panel; the output of conversion and control module is connected with transforming circuit; the output of described transforming circuit is connected with button cell group after charge controller, is connected with an overload protection module between central controller and the input of button cell group.

In such scheme, the output voltage of described charge controller can be 3.0 ~ 8.5V.

The beneficial effects of the utility model are:

1, the utility model installs the lighting device being provided power supply by solar energy on the shank of the key of normal key, not only achieves the object of quickly unlocking at night, enabling, easy to use, structure is simple;

2, by light energy conversion in solar irradiation for electric energy provides power supply to rechargeable button cell, to make LED luminous, during use, brightness is large, and does not need to change battery, energy-conserving and environment-protective.
