As optical and semiconductor manufacturing technology advances, Liquid Crystal Display (hereafter LCD) is widely used in all kinds of electronic appliances. LCD has several advantages, such as high resolution, small volume, light weight, low driving voltage, low power consumption and broad application. Thus, LCD application has become popular in portable TVs, cellular phones, camcorders, notebook personal computers (PCs), desktop PCs, projectors and other consumer electronics or computer products. LCD has become a mainstream technology in the display market.
Generally speaking, an LCD is secured to an upper cover of a notebook PC. The upper cover can be opened while turning on the notebook PC. An LCD is exposed after opening the upper cover. The upper cover is connected pivotally to a mainframe of the notebook PC. Therefore, The LCD can be adjusted to a desired position by rotating the upper cover in relation to the mainframe.
Because a notebook PC is portable, a user often carries it out of the office to a desired place. In different circumstances, the notebook PC is used for demonstration purposes. However, traditionally, the LCD of notebook PC doesn't have an ability to display information in as large viewing angle as to all of the people around it. Thus, a new model PC entitled Tablet Personal Computer has been introduced to the market. A tablet PC has a 180-degree rotatable LCD panel. A Tablet Personal Computer (hereafter tablet PC) providing both keyboard input and manual input not only changes computer use habits but also creates a milestone for information technology. Moreover, the tablet PC operation systems can provide a manual input function. The tablet PC has accordingly a user-friendly manual input interface and a 180-degree rotatable LCD panel. Therefore, persons around the tablet PC can easily read the information displayed on the LCD by rotating the LCD panel.
The LCD panel's two degrees of rotation function may cause the LCD panel to shake or give rise to other unsteady circumstances. Therefore, a means for angular fixing of the LCD panel after moving the same to a desired position is essential. For the forgoing reasons, there is a need for providing a steady input and display environment.
It is therefore an objective of the present invention to provide a swivel hinge apparatus with an angular fixing function in order to provide a steady input and display environment.
In accordance with the foregoing and other objectives of the present invention, a swivel hinge with angular fixing structure is employed to connect a mainframe and a display means of a notebook computer. The swivel hinge includes a fixture part, a fixture friction ring, a rotation part, a rotation friction ring, and an elastic ring. The fixture part mounted on the mainframe has a through hole in the center thereof. The fixture friction ring fixed on the fixture part has at least one holder on the surface. The rotation friction ring fixed on the rotation part has at least one slot in the surface thereof. The elastic ring is located between the fixture part and the fixture friction ring. If the slot and the holder on the friction ring fit into each other, the desired angular fixing function is provided.
According to one preferred embodiment of present invention, the rotation part includes a rotation plate and a rotation base. The rotation plate connects to the rotation base via the through hole of the fixture part. That is, the fixture part is placed between the rotation plate and the rotation base.
According to one preferred embodiment of present invention, the fixture friction ring alternatively has at least one slot, and the rotation friction ring alternatively has at least one holder. If the holder and the slot fit each other, the desired angular fixing function is provided. The elastic ring can be disposed between the rotation friction ring and the rotation part, or be disposed between the fixture friction ring and the fixture part. But the elastic ring cannot be disposed between the fixture friction ring and the rotation friction ring.
In conclusion, the swivel hinge apparatus of present can provide not only a multi-angle fixing function but also a steady input and display environment for users.
FIG. 1 illustrates a perspective view of a swivel hinge apparatus according to one preferred embodiment of this invention;
FIG. 2 illustrates an exploded view of a swivel hinge apparatus according to one preferred embodiment of this invention;
FIG. 3A illustrates a perspective view of a rotation friction ring according to another preferred embodiment of this invention;
FIG. 3B illustrates a perspective view of a fixture friction ring according to another preferred embodiment of this invention; and
FIG. 3C illustrates a perspective view of an elastic ring according to another preferred embodiment of this invention.
FIG. 1 illustrates a perspective view of a swivel hinge apparatus according to one preferred embodiment of this invention. The swivel hinge apparatus of the present invention has two rotational degrees of freedom. A rotation direction 10 indicates rotation around the X-axis. A LCD panel is opened and closed in the rotation direction 10. A rotation direction 12 indicates rotation around the Z-axis. A LCD panel's display view can be adjusted in the rotation direction 12. The purpose of present invention is to provide an angular fixing function. The detailed structure of the swivel hinge apparatus is described below.
FIG. 2 illustrates an exploded view of a swivel hinge apparatus according to one preferred embodiment of this invention. The swivel hinge apparatus includes an X axis hinge 16, a rotation plate 11, a fixture friction ring 20, a rotation friction ring 18, a fixture part 22, an elastic ring 24 and a rotation base 26. The fixture part 22 is fixed to a mainframe of a notebook PC by fastening via screw holes 27. The X-axis hinge 16, mounted on the rotation plate 11, is employed to connect to a display means of a notebook computer. The rotation plate 11 is fixed to the rotation base 26 by bolts. A combination of the rotation plate 11 and the rotation base 26 is docked inside the fixture part 22 and the combination can rotate in relation to the fixture part 22. For example, the rotation plate 11 and the rotation base 26 are fixed by fastening screws 14 to holes 29 via holes 13 and the through hole 36. The rotation plate 11 and the rotation base 26 rotate simultaneously in relation to the fixture part 22.
Referring to FIG. 2, several round rings between the fixture part 22 and the rotation parts (including a rotation plate 11 and a rotation base 26) are employed to conduct angular fixing function. The fixture friction ring 20 (such as a circular ring) is fixed to the fixture part 22 by fitting a holder 21 of the fixture friction ring 20 to a slot 32 of the fixture part 22. That is, the fixture part 22 and fixture friction ring 20 rotate simultaneously.
Referring FIG. 2 again, a rotation friction ring 18 is a corresponding component of the fixture friction ring 20. The rotation friction ring 18 (such as a circular ring) is fixed to the rotation part (such as the rotation plate 11 and the rotation base 26) by respectively fitting a holder 17 of the rotation friction ring 18 to a slot 30 of the rotation plate 11 and/or to a slot 34 of the rotation base 26. Namely, the rotation friction ring 18 is fixed to a rotation plate 11 and/or a rotation base 26. In other words, the rotation friction ring 18 and the rotation part can rotate simultaneously
The Z-axis hinge's angular fixing function is conducted by fitting position elements (15 and 15 a, 19 and 19 a) respectively on the fixture friction ring and the rotation friction ring together. Referring FIG. 3A, 3B and 2, an angular fixing function is provided if a second position element 15 and 15 a on the rotation friction ring 18 is fitted into a first position element 19 and 19 a on the fixture friction ring 20. The first position element 19 and 19 a described above can be a holder (a convex member), and the second position element 15 and 15 a can be a slot (a concave portion). Because the rotation friction ring 18 and the fixture friction ring 20 are corresponding components, the position elements (a holder or a slot) on the friction rings 18 or 20 can be replaced by each other. That is, the holder (convex member) and the slot (concave portion) can be respectively designed on the fixture friction ring and the rotation friction ring, or can be respectively designed on the rotation friction ring and the fixture friction ring. The desired angular fixing numbers can be decided by how many position elements (holders and slots) on the friction rings. For example, if an interval between two position elements in a circular friction ring is 180 degrees, there will be two angular fixing positions in the circular friction ring. If an interval between two position elements in a circular friction ring is 90 degrees, there will be four angular fixing positions in the circular friction ring.
In addition, in order to provide desired angular fixing positions on the circular friction ring, the position element can be made in specific positions. For example, the position elements can be made at 0 degrees, 90 degrees, and 180 degrees of the circular friction ring, resulting in an angular fixing function of 0 degrees, 90 degrees, and 180 s provided around the Z axis.
In one preferred embodiment of present invention, an elastic ring can be added in a swivel hinge apparatus to provide steady angular fixing function. For example (referring to FIG. 2), an elastic ring 24 is disposed between the rotation friction ring 18 and the rotation base 26. Referring FIGS. 3C and 2, the elastic ring 24 includes a spring ring, a plastic elastic ring, and a metal elastic ring, such as a circular wavy elastic ring. The elastic ring 24 can provide axial pushing forces such that the holder and the slot can fit firmly. The position of the elastic ring 24 can be disposed between the rotation friction ring 18 and the rotation part 26, or can be disposed between the fixture friction ring 20 and the fixture part 22, but the position of the elastic ring cannot be disposed between the rotation friction ring 18 and the fixture friction ring 20.
Referring to FIG. 2, a through hole 36 in the center of a swivel hinge apparatus provides a space for message lines and power lines layout. These message lines and power lines are employed to provide power and to communicate messages. A swivel hinge apparatus can rotate clockwise or counter-clockwise. However, a rotation range of a swivel hinge apparatus needs to be limited to avoid power line breakage because of twisting.
For example (referring FIG. 2), pin holders 23 are respectively installed on two sides of the fixture part 22 and corresponding pins 9 are under the rotation plate 11. The pin holders 23 are employed to block the range of motion of the pins 9 such that the rotation plate 11 rotates within a predetermined rotation direction and range. In one preferred embodiment of present invention, the swivel hinge apparatus can provide a rotation range of 180 degrees around the Z-axis.
