Embodiment

Below in conjunction with accompanying drawing 1-5, specify the utility model.

As shown in Figures 1 and 2, the double-action mechanism of the hinge that the utility model relates to, wherein, hinge mainly comprises axle center 10, and axle center 10 is equipped with first assembled plate 12 and second assembled plate 13, first assembled plate 12 has the non-circular hole that is fixed in axle center 10, and second assembled plate 13 have can be in the axle center 10 circular holes that pivot, first assembled plate 12 can be driven mutually with axle center 10, and relative second assembled plate 13 produces first pivot movement, and axle center 10 and second assembled plate, the 13 corresponding positioning parts that in first pivot movement, constitute positioning relation that are provided with, in embodiment of the present utility model, the positioning part is the projection that is fastened; And axle center 10 wears in addition and is fixed with action piece 17, action piece 17 is provided with resistance portion 171, resistance portion 171 is sector structure as shown in FIG., make action piece 17 carry out first pivot movement synchronously with axle center 10 interlocks, in addition, axle center 10 also is equipped with elements such as friction pads 14, torsion pad 15, resilient pad 16, is used to provide needed torsion in first pivot movement.

Double-action mechanism includes fixed base 20, fixed base 20 sees through pivot 21 and is articulated with coupling component 22, coupling component 22 is provided with the first resistance portion 221 and the second resistance portion 222, and the first resistance portion 221 is resisted by action piece 17 in first pivot movement of action piece 17, making the first resistance portion 221 and the second resistance portion 222 serves as that axle produces one second pivot movement with the pivot points of coupling component 22, so just constituted main framework of the present utility model, make the utility model when rotating first assembled plate 12, can see through action piece 17 and drive coupling component 22 motions.

As Fig. 3, Fig. 4 and shown in Figure 5 shown in, hinge and double-action mechanism are arranged on the notebook computer 30, wherein, the screen 31 that connects notebook computer 30 by first assembled plate 12, the keyboard 32 that is connected notebook computer 30 by second assembled plate 13 with fixed base 20, and keyboard 32 bottoms have the thermovent 321 of corresponding second a resistance portion 222, and be provided with the dissipating cover 33 that covers thermovent 321 in keyboard 32 bottoms, dissipating cover 33 1 ends are articulated in keyboard 32 bottoms, and the other end connects keyboard 32 bottoms with the elastic component as spring.

When screen 31 and keyboard 32 covered, hinge was closed state, and dissipating cover 33 is subjected to the gravity of notebook computer 30 to be close proximity to keyboard 32 bottoms with the elastic force effect of elastic component and to cover 321 (as shown in Figure 3) of dispelling the heat; When screen 31 relative keyboards 32 are raised, first assembled plate, 12 interlock axle center 10 and action piece 17, relative second assembled plate 13 produces first pivot movement, at this moment, action piece 17 is with the first resistance portion 221 of its resistance portion 171 pushing and pressing coupling components 22, making the first resistance portion 221 and the second resistance portion 222 is that axle produces second pivot movement with the pivot points, and pass the thermovent 321 of keyboard 32 bottoms and promote dissipating cover 33 with the second resistance portion 222, with this dissipating cover 33 is pushed open and exposed thermovent 321, so that the heat of notebook computer 30 inside is shed, and keyboard 32 is supported and tilt (as shown in Figure 4); Apply the power of raising if continue to screen 31 this moment, then first assembled plate 12 will continue relative second assembled plate, 13 works, first displacement movement with axle center 10, positioning part up to the blocking axle center, positioning part 10 of second assembled plate 13, and constitute positioning relation and reach locating effect (as shown in Figure 5).

In sum, the utility model wears the action piece 17 that is fixed with axle center 10 pivot in unison mainly due to the axle center 10 of hinge, and be provided with fixed base 20 and be articulated in the coupling component 22 of fixed base 20 in double-action mechanism, when axle center 10 pivots, can rely on action piece 17 pushing and pressing coupling components 22, and make coupling component 22 pivot in unison, therefore, when being applied to as notebook computer 30 cover-lifting type electronic devices such as grade, the utility model can have following advantage:

1. after screen 31 was raised in first pivot movement, dissipating cover 33 1 ends were supported by coupling component 22 and are pushed away keyboard 32 bottoms, and relative, keyboard 32 just can form the angle of inclination with desktop, so that the user knocks.

2. hold, dissipating cover 33 will expose the thermovent 321 of being located at keyboard 32 bottoms after being released by coupling component 22, dispels the heat with auxiliary.

More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, for a person skilled in the art, under the prerequisite that does not break away from the utility model principle, the change of making should be considered as belonging to protection domain of the present utility model.
