Abstract
The utility model discloses a wireless keyboard, which comprises a keyboard body and a wireless signal receiver. The keyboard body consists of a key matrix circuit, a wireless signal transmitting unit and a control unit, and an electric quantity detecting unit used for detecting the electric quantity of a power source of the keyboard body is further arranged on the keyboard body, is electrically connected with the control unit and consists of an electric quantity detecting circuit and a low electric quantity indicator lamp. The keyboard electric quantity detecting unit is adopted, the electric consumption condition of the keyboard can be timely reflected, a user can be informed that the electric quantity is low by the low electric quantity indicator lamp so as to replace a battery or take other measures in time, and inconvenience caused by loss of information of input equipment of a computer is avoided.
Description
Technical field
The utility model relates to field of computer peripherals, relates in particular to a kind of Wireless Keyboard with low electric quantity indication function.
Background technology
Pass through Universal USB interface or PS interface transmission information between traditional calculating machine and each input-output device, yet the sort signal transmission mode receives the restriction of peripheral hardware transmission cable length, use inconvenience thereby cause.The wireless communication technology of using has at present remedied this defective; The Wireless Keyboard technology is with conventional keyboard break keyboard body and signal receiver two parts; The keyboard body is provided with wireless signal transmitter, and signal receiver is through Universal USB interface or PS interface and compunication.Yet Wireless Keyboard is generally in use because the independent power supply phenomenon that exists electric weight to exhaust, causes occurring suddenly in the use of computing machine the situation of keyboard outage easily, causes the computing machine input/output signal to be lost.
The utility model content
The purpose of the utility model provides and a kind of keyboard battery electric quantity information can be provided in time, has low electric quantity indication function, sun power capable of using, and Wireless Keyboard that can waterproof.
In order to achieve the above object; The utility model provides a kind of Wireless Keyboard; Comprise keyboard body and wireless signal receiver, the keyboard body comprises key matrix circuit, wireless signal transmission unit and control module, it is characterized in that: also be provided with the electric weight detecting unit that is used to detect keyboard body electric quantity of power supply on the said keyboard body; Said electric weight detecting unit and control module electrically connect, and comprise electric weight testing circuit and low electric weight pilot lamp.
Also be provided with low light level solar panels on the said keyboard body, said low light level solar panels and keyboard circuit electrically connect, and which is provided with the light-passing board that is used for printing opacity.
Said light-passing board adopts the PMMA material of high transmission rate to process, and adopts waterproof technique to be arranged on the said keyboard body.
Said keyboard body bottom also is provided with some osculums that are used to prevent ponding.
The utility model adopts the design of keyboard electric weight detecting unit, can in time reflect keyboard electricity consumption operating position, and when electric weight is low; Inform that through low electric weight pilot lamp the user in time changes battery and takes other measures, prevents that computer entry device information dropout from bringing inconvenience, in addition; The utility model adopts transmittance high; The light-passing board design that spotlight effect is good improves the conversion of solar energy of low light level solar panels, and the utility model also is provided with osculum; Can in time the water that is spread across on the keyboard be discharged the keyboard body interior, prevent the keyboard main body structure is caused corrosion.
