ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an elevated device, especially a structure for a keyboard of a notebook computer, and by which a movement of a guiding board lowers the height of the keyboard to reach a state of storage.
BACKGROUND OF THE INVENTION
In the prior art of a keyboard of a notebook computer, the key of the keyboard is usually constructed on a rubber and a relative circuit with touching and controlling functions (following is simply called circuits) by a scissors type of structure.
FIG. 1
shows the structure of single key, wherein the key
1
is arranged on a base
10
, and in which comprises the key-top-lid
11
provided for directly knocking and the scissors-device
12
provided for rising and lowering the key-top-lid
11
. This scissors-device
12
is designed by the intersection of a pair of connection rods to form a turning scissors configuration. Between the two connection rods of the scissors-device
12
and under the key-top-lid
11
, there is a formation of a containing space, which provides an installation of the elastic rubber
13
for provision of recovery force of the pressing. The elastic rubber
13
has a hollow portion, and there is a corresponding circuit contact disposed on the base
10
where under the hollow portion of the elastic rubber
13
(not shown).
In the following explanation, with respect to the illustration of the key
1
and the symmetrical scissors-device
12
, only shows a side view with the connection rod of its single side, and the elastic rubber
13
and relative circuits are omitted. In the different figures, the same reference number and name will represent an element in the same position, and the simple drawing will facilitate the proceeding of clarification of the written explanation.
Please refer to
FIG. 2
, there is an illustration of the sectional structure of a prior art scissoring key structure, wherein the scissors-device
12
is constructed between the internal surface
110
of the key-top-lid
11
and the base
10
. The scissors-device
12
comprises a first connection rod
121
and a second connection rod
122
. The first connection road
121
and the second connection rod
122
are pivoting jointed on a pivot point
123
of their middle sections to form an intersection structure which can be a relatively turning scissors structure. On the installation of the first connection rod
121
, the first upper end
1211
and the flange
1101
of the extension of the internal surface
110
of the key-top-lid
11
form a turning, pivoting joint match. Relative to the first upper end
1211
of the first connection rod
121
, the first lower end
1212
and the third flange
101
extended from the base
10
form a slidably and pivotally sliding match. On the installation of the second connection rod
122
, the second upper end
1221
and the second flange
1102
of the extension of the internal surface
110
of the key-top-lid
11
form a glideably and turning match. Relative to the second upper end
1221
of the second rod
122
, the lower second end
1222
and the fourth flange
102
extended from the base
10
forms a turning pivoting joint match.
In the illustration of
FIG. 2
of the prior art scissors key structure, the first connection rod
121
and the second connection rod
122
form a balancing scissors elevating structure (namely, the scissors-device
12
). The key-top-lid
11
is an application end. Both ends of each connection rod (the first connection rod
121
or the second connection rod
122
) and the framework (i.e. key-top-lid
11
and base
10
) separately form a turning, pivoting joint match, and a gliding, pivoting match. With these, during the operation of pressing key, it may keep a side of the scissors-device
12
(including one side of the first upper end
1211
and the second lower end
1222
) in one substantially vertical line L, and the another side (including one side of the second upper end
1221
and the first lower end
1212
) processes the up and down of the horizontally movement by the excessive travel of the gliding match.
Due to the continuous improvement of today's technology, the electronic product is developed rapidly. Anything concerning to electronic relative product must be required with the properties of shortness, smallness, lightness, thinness and convenience of carry. Therefore, the above-mentioned keyboard structure still belongs to an acceptable range for the application of desktop personal computer. But when applying in the portable notebook computer, the mentioned keyboard structure is a big barrier of the reducing the thickness of a computer. Relatively, it will make that the volume of the portable notebook is too big to carried easily, and contradict the idea of requirement of shortness, smallness, lightness and thinness of the electronic product, therefore, the breakthrough of this technological barrier is the most urgent.
SUMMARY OF THE INVENTION
The major object of this invention is to provide an elevated and lower keyboard apparatus, by a horizontal movement of a guiding board to make a key structure vertically rising up and lowering down and to reach the function of lowering down the keyboard apparatus.
The another object of this invention is to provide an elevated and lower keyboard apparatus, by a horizontal movement of a guiding board to make the key structure vertically rising up and lowering down and to accomplish a keyboard device of a notebook computer having an application state and a storage state in different heights of keyboard for facilitating the necessity of reducing the thickness of a notebook.
To reach the above-mentioned objects, the elevated and lower keyboard apparatus of this invention comprises a base, plural of key-top-lids, plural of scissors-devices and a guiding board.
The scissors-devices comprise a first scissors-device and a second scissors-device. The first scissors-device has a first connection rod and a second connection rod, and the two connection rods are intersected to form a turning scissors configuration. The two ends of the first scissors-device are separately connected to the base and the first key-top-lid. The first key-top-lid is moved in upward and downward manner relatively to the base by the first scissors-device.
The second scissors-device has a third connection rod and a fourth connection rod. The two connection rods are intersected to form a turning scissors configuration. The two ends of the second scissors-device are separately connected to the base and the second key-top-lid. The second key-top-lid is moved in upward and downward manner relatively to the base by the second scissors-device.
The guiding board is disposed on the base and moved between a first position and a second position. There are a first guiding block and a second guiding block formed on the guiding board. When the guiding board is moved from the second position to the first position, the first guiding block and the second guiding block separately press the second connection rod and the fourth connection rod to make the first key-top-lid and second key-top-lid lowering down relatively to the base. When the guiding board is moved from the first position to the second position, the first guiding block and the second guiding block separately releases the second connection rod and the fourth connection rod to make the first key-top-lid and the second key-top-lid rising up relatively to the base.
Another embodiment of this invention is an application on a keyboard apparatus of a notebook computer. The notebook computer comprises a main body part and a screen part, and the screen part is pivotally connected and covered on the main body part. The keyboard apparatus is disposed inside the main body part, which comprises a base, plural of key-top-lids, plural of scissors-devices, a guiding board and at least one operation part.
The scissors-devices comprise a first scissors-device and a second scissors-device. The first scissors-device has a first connection rod and a second connection rod, and the two connection rods are intersected to
