Description

LCD power supply control structure

[technical field]

The utility model is about a kind of power supply control structure, is meant a kind of hinge type LCD power supply control structure especially.

[technical background]

The battery capacity of employed portable electric appts is limited on the market at present, therefore, often needs to consider to save power issue in the design and use process.And the most of portable electric appts at present, as notebook computer, be when start to monitor power supply, and need close whole computer power simultaneously will close display power supply the time.Therefore, generally speaking, display always is in opening during computer work, and this situation tends to waste power supply.

In order to address the above problem, the people in the industry proposes the whole bag of tricks, the energy-saving circuit and the method for a kind of display that is disclosed for No. 99123856.7 as Chinese patent application, as described in this invention, computer is not work in the preset time section, it can be according to driven primary power and/or the heating power supply of closing display of a plurality of display power management sig-malings, thereby reduce the power consumption of display, but this invention is the effect that reaches power saving by the improvement of circuit aspect, cost is higher, and inconvenient operation.In addition, industry also has the state that inductive switch is controlled the normal unlatching of display or entered battery saving mode that hangs that adopts, but this suspension inductive switch is installed in notebook computer or other electronic equipment with exposed mostly, influence the attractive in appearance of these equipment, and its structural strength is relatively poor, damages easily.

[summary of the invention]

The purpose of this utility model is to provide a kind of LCD power supply control structure easy and simple to handle, with low cost.

Technical problem to be solved in the utility model realizes by following technical proposal: the utility model LCD power supply control structure comprises that a LCD, a base, a hinge means, a loading plate and hang inductive switch.Wherein this hinge means comprises an axis body and a sleeve, and this axis body locking is on this base, and this sleeve is fixed on this LCD.This axis body has a stationary shaft, and this jacket casing is located on this stationary shaft and can rotates around it.This sleeve has an Actuator Division.This loading plate locking is on this axis body, and the one end is fixed this suspension inductive switch.This suspension inductive switch has an elasticity effector.When rotating this LCD, this LCD will drive this sleeve around this stationary shaft rotation, when this LCD rotates to certain angle, the effector of the Actuator Division on this sleeve and this suspension inductive switch offsets, this effector shrinks in hanging inductive switch owing to pressurized, thereby the power supply that cuts off between LCD and the host computer connects, and makes LCD be in off-position.On the contrary, when the effector of the Actuator Division on this sleeve and this suspension inductive switch separated, the power supply between LCD and the host computer was connected, and LCD is in normal opening.

LCD power supply control structure of the present utility model, mainly be to consider from the mechanism aspect, a kind of device that reduces the LCD loss of power is provided, this device is mainly controlled one by a hinge means and is hung the effect that inductive switch can be realized power saving, easy to operate, with low cost.
