Abstract

The utility model relates to a power supply button protective mechanism of a notebook computer. The protective cover mechanism comprises a protective cover, rotating shaft support arms and torsion springs. Both sides of the protective cover are provided with the rotating shaft support arms. The rotating shaft support arms can be arranged on the case shell of the computer. Two torsion springs are assembled on the rotating shaft support arms. When the user uses the computer, the user opens the protective cover and the power supply button can be pressed to turn on the computer power supply by the power supply button protective mechanism. Then the protective cover can automatically reset to the original closed position to avoid the abnormal power off of the computer.

Description

Notebook computer power knob protection mechanism

Technical field

The utility model is about the notebook computer design of shell, especially relates to the button that is used to protect power supply by false touch, misoperation, or the power knob over cap of maloperation.

Background technology

The power supply of tradition computer there is no relevant press button protecting device.For desktop computer, power supply is improper closes the little chance of operator because of maloperation causes; But the computer volume diminishes day by day, for notebook computer, if there is not corresponding apparatus for protecting power supply, because its keyboard is separated by very near with the power knob distribution distance, the user is when operating computer, on the one hand hard disk is caused damage by the computer abnormal shutdown because of the false touch power knob makes very easily, shorten the serviceable life of hard disk; On the other hand, also can cause, moil before making and throw to the winds the waste of manpower financial resources because the archives material that work fashion is not stored runs off.

The utility model content

Fundamental purpose of the present utility model; provide a kind of notebook computer power knob protection mechanism; over cap of the present utility model both sides are provided with the rotating shaft support arm; respectively be preset with a groove on the rotating shaft support arm; simultaneously; respectively be assembled with a torque spring on the rotating shaft support arm, torque spring one end peaks at the casing medial surface from bottom to top, and the other end then is embedded on the support arm in the groove.By this power knob protection mechanism, the user opens over cap and can press power knob unlatching computer power when using computer, and subsequently, over cap can cover go back to the position of closing originally automatically, to avoid the computer abnormal shutdown.

For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

Embodiment

See also shown in Figure 1; power knob protection mechanism of the present utility model is provided with an over cap 2030; be provided with rotating shaft support arm 2050 in these over cap 2,030 two sides; respectively be preset with a groove 2051 on the rotating shaft support arm 2050; simultaneously, respectively be assembled with a torque spring 2040 on the rotating shaft support arm 2050, torque spring 2,040 one ends peak at the casing medial surface from bottom to top and (see also Figure 1A; 1B), the other end then is embedded in the groove 2051 default on the rotating shaft support arm 2050.The distance that two rotating shaft support arms are 2050 is greater than the length of button hole 2025 on the notebook computer casing (seeing also Fig. 2 B).

This over cap 2030 has an arc arcuate configuration away from rotating shaft support arm 2,050 one sides; and shrinking away from theshell body pivot end is far away more, its arch upward degree also with increase gradually, like this; when over cap 2030 is in when covering state, the operator can stretch into finger easily and over cap 2030 is pulled open.

See also shown in Figure 1A, torque spring 2,040 one end A are bottom-up withstanding on casing 2010 medial surfaces, other end B then is embedded in location in the groove default on the rotating shaft support arm 2,050 2051, so utilize the A end of torque spring 2040 to withstand the reverse elasticity restoring force that casing 2010 is produced, make this over cap 2030 all the time to direction of arrow rotation as shown, thereby make over cap 2030 can keep closing state at any time; Only put at finger and pull, over cap 2030 just can be pointed a little and be backed down, and waits to point a withdrawal, and over cap 2030 will keep closed condition again, shown in Figure 1B.

See also shown in Fig. 2,3; difference according to notebook computer power knob arrangement; this protection mechanism can be installed between the keyboard distributive province and rotating shaft 200 in notebook computer main frame body 100 fronts (seeing also shown in Figure 2), also can be installed in the side (seeing also shown in Figure 3) of notebook computer main frame body 100.

See also shown in Figure 2; when over cap mechanism is installed between the keyboard distributive province in notebook computer main frame body 100 fronts and the rotating shaft 200; when the user desires power-on use notebook computer; shown in Fig. 2 A; power knob over cap 2030 is pulled open to opening direction; shown in Fig. 2 B; over cap 2030 is pulled to the location; just can expose the power knob 2020 in button hole 2025; at this moment; just can press power knob 2020, after pressing power knob 2020, hand be removed, at this moment; shown in Fig. 2 C; power knob over cap 2030 just can be owing to the effect of torque spring (among the figure indicate), and over cap 2030 is reposition, and reaches the function of protection power knob 2020.

Please consult shown in Figure 3 again; when this over cap mechanism is installed in the side of notebook computer main frame body 100; see also shown in Fig. 3 A ~ C; situation when its method of operating is installed between the keyboard distributive province in notebook computer main frame body 100 fronts and the rotating shaft 200 with this over cap mechanism repeats no more.

This case the above embodiments; only in order to illustrate possible example of the present utility model; the interest field that the utility model is advocated; be not limited thereto; such as be familiar with present technique field person; according to the disclosed technology contents of the utility model, can think easily and and the various equivalence that its detail is carried out is changed example, all should be included in protection domain of the present utility model.
