Yet when needs used laptop or PDA at the dark place, the user often was difficult to see clearly the position of button and touching control rod, so that cause the difficulty in the use.

The utility model content

For solving above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of input block and a kind of portable electron device that uses this input block that in the dark also can handled easily.

The utility model provides a kind of input block of electronic installation, comprises circuit component; Touching control rod electrically connects described circuit component; Emit beam to described touching control rod light-emitting component on every side, be arranged on the described circuit component and close described touching control rod.

In a preferred embodiment, aforementioned input block more comprises base plate, and in order to the support circuit element, wherein circuit component is between touching control rod and base plate.

In another preferred embodiment, aforementioned input block more comprises light-guide device, is arranged on the circuit component and contiguous light-emitting component, and aforementioned light is to be directed to around the touching control rod by light-guide device.

In another preferred embodiment, the aforementioned circuit element is a film circuit board.

In a preferred embodiment again, aforementioned light-emitting component is a light emitting diode.

In a preferred embodiment again, aforementioned input block more comprises a plurality of light-emitting components.

In a preferred embodiment again, aforementioned input block more comprises a plurality of buttons, is arranged on the circuit component and contiguous touching control rod.

In a preferred embodiment again, aforementioned touching control rod is arranged at the space between a plurality of buttons.

In a preferred embodiment again, aforementioned input block is a keyboard.

In a preferred embodiment again, aforementioned electronic is laptop or PDA.

The utility model also provides a kind of portable electron device that uses aforementioned input block, and wherein said input block comprises: circuit component; Touching control rod electrically connects described circuit component, it is characterized in that described input block also comprises the light-emitting component that emits beam around described touching control rod, is arranged on the described circuit component and close described touching control rod.

In sum, the utility model helps the user and operate touching control rod under the environment of dark, and can be widely used in portable type electronic products such as laptop or PDA by around touching control rod light-emitting component being set.

Embodiment

At first see also Fig. 1, this figure is the input block synoptic diagram of expression portable electron device (for example laptop or PDA).Input block in the present embodiment is keyboard K, and it mainly comprises base piece B, a plurality of button C and touching control rod P.As shown in Figure 1, aforementioned base piece B then comprises base plate S and circuit component M (for example being film circuit board), wherein button C and touching control rod P all are arranged on the circuit component M and with circuit component M and electrically connect, and base plate S then is arranged at circuit component M below, in order to support aforementioned circuit element M.

In Fig. 1,, therefore under the environment of dark, often be difficult for seeing clearly its position because the volume of aforementioned touching control rod P is less and be arranged at gap between a plurality of adjacent key C; In view of this, the utility model is by being provided with light-emitting component near touching control rod P, and emits beam by light-emitting component and to be beneficial to the user and to operate touching control rod P in the dark.

Then see also Fig. 2, this figure is the sectional view of A-A in the presentation graphs 1.As shown in Figure 2, aforementioned touching control rod P electrically connects by connector H and circuit component M, and the user can force in touching control rod P along different directions when operation, so as to reaching the function of control vernier.In particular, near touching control rod P, be provided with at least one light-emitting component L (for example light emitting diode), wherein light-emitting component L is arranged at circuit component M to go up and electrically connect with circuit component M, its position is then near touching control rod P, even if the user still can see through light-emitting component L and emits beam seeing the position of touching control rod P clearly in the dark thus, and then promotes the convenience that it uses.

Then see also Fig. 3 again, in another preferred embodiment, also light-guide device G can be set above light-emitting component L, above-mentioned light-guide device G is for example for being arranged at the light guide plate on the circuit component M, around the light guiding touching control rod P that can more efficiently light-emitting component L be sent thus, and then reach lifting brightness and effect of saving energy.
