DETAILED DESCRIPTION
Please refer to FIG. 1. FIG. 1 is a perspective drawing of a computer 50 according to a preferred embodiment of the present invention. The computer 50 can be a notebook computer. The computer 52 includes a housing 52. The housing 52 includes a surface 521. The housing 52 can be a display housing, such as an LCD monitor housing. The computer 50 further includes two first rotary modules 54 disposed on both sides of the housing 52 respectively, and a second rotary module 56 disposed on an upper side of the housing 52. The number and the position of the first rotary module 54 and the second rotary module 56 are not limited to the embodiment illustrated in FIG. 1. The first rotary module 54 and the second rotary module 56 can be disposed selectively. That is, the computer 50 can only have the first rotary module 54 or the second rotary module 56 depending on design demand.
Please refer to FIG. 2 to FIG. 4. FIG. 2 is a diagram of the first rotary module 54 and the second rotary module 56 installed inside the housing 52 according to the preferred embodiment of the present invention. FIG. 3 is an exploded drawing of the first rotary module 54 according to the preferred embodiment of the present invention. FIG. 4 is a sectional diagram of the first rotary module 54 installed inside the housing 52 according to the preferred embodiment of the present invention. Both of the first rotary modules 54 have the same structure and working principle, and thus one of the first rotary modules 54 is introduced as follows. A first opening 58 is disposed on the housing 52, and a first containing space 60 is formed inside the housing 52. The first rotary module 54 is installed inside the first containing space 60 in a rotatable manner, such as being pivoted to the housing 52. The first rotary module 54 includes a bar 62 pivoted to the housing 52. The bar 62 includes a first side 621 and a second side 622 opposite to the first side 621. The first side 621 and the second side 622 can be planes respectively. The second side 622 of the bar 62 and the surface 521 of the housing 52 can be made of same material and have same paint color so that the second side 622 of the bar 62 corresponds with the surface 521 of the housing 52 in an outward appearance. The first rotary module 54 further includes a pad 64 disposed on the first side 621 of the bar 62. The pad 64 can be made of rubber material. When an LCD monitor of the computer 50 is close, the pad 64 can support the LCD monitor for preventing from being worn away. The computer 50 further includes two first magnetic components 66 connected to both ends of the bar 62 of the first rotary module 54 respectively. The first magnetic component 66 can be glued to or welded with the bar 62. A second magnetic component 68 and a third magnetic component 70 are disposed on both sides of each first magnetic component 66. The first magnetic component 66 can be a permanent magnet and a circular structure. The second magnetic component 68 and the third magnetic component 70 can be electromagnets respectively having an iron core and copper enameled wires wound around the iron core.
Please refer to FIG. 5. FIG. 5 is a diagram of the first rotary module 54 rotating from a second position to a first position according to the preferred embodiment of the present invention. When the first rotary module 54 is located in the second position, the pad 64 is contained inside the first containing space 60 of the housing 52 and the second side 622 of the bar 62 is level with the surface 521 of the housing 52 substantially. Because the second side 622 of the bar 62 and the surface 521 of the housing 52 can be made of same material and have same paint color, the second side 622 of the bar 62 and the surface 521 of the housing 52 perform as an integrated body in the outward appearance. A switch 72 electrically connected to the second magnetic component 68 and the third magnetic component 70 can electrify the second magnetic component 68 and the third magnetic component 70 with a first current direction so that the second magnetic component 68 and the third magnetic component 70 attract the first magnetic component 66. For example, the switch 72 can electrify the second magnetic component 68 so as to generate a magnetic pole of an end of the second magnetic component 68 close to an end of the first magnetic component 66 with an opposite magnetic pole. As shown in the upper diagram of FIG. 5, the end of the second magnetic component 68 close to the first magnetic component 66 is an N pole, and the end of the first magnetic component 66 close to the second magnetic component 68 is a S pole correspondingly. Similarly, the end of the second magnetic component 68 close to the first magnetic component 66 can be an S pole, and the end of the first magnetic component 66 close to the second magnetic component 68 can be a N pole correspondingly. On the other hand, the switch 72 can electrify the third magnetic component 70 so as to generate a magnetic pole of an end of the third magnetic component 68 close to an end of the first magnetic component 66 with an opposite magnetic pole. As shown in an upper diagram of FIG. 5, the end of the third magnetic component 70 close to the first magnetic component 66 is an S pole, and the end of the first magnetic component 66 close to the third magnetic component 70 is an N pole correspondingly. Similarly, the end of the third magnetic component 70 close to the first magnetic component 66 can be an N pole, and the end of the first magnetic component 66 close to the third magnetic component 70 can be an S pole correspondingly. At this time, the second magnetic component 68 and the third magnetic component 70 attract the first magnetic component 66 with each other so as to fix the first rotary module 54 in the second position.
The first rotary module 54 needs to rotate from the second position to the first position when using the pad 64. The switch 72 can electrify the second magnetic component 68 and the third magnetic component 70 with a second current direction opposite to the first current direction so that the second magnetic component 68 and the third magnetic component 70 repulse the first magnetic component 66. For example, the switch 72 can electrify the second magnetic component 68 so as to generate a magnetic pole of an end of the second magnetic component 68 close to an end of the first magnetic component 66 with a same magnetic pole. As shown in the middle diagram of FIG. 5, the magnetic fields of the second magnetic component 68 and the third magnetic component 70 convert after being electrified with the second current direction opposite to the first current direction. That is, the end of the second magnetic component 68 close to the first magnetic component 66 is a S pole, and the end of the third magnetic component 70 close to the first magnetic component 66 is a N pole so that there are repulsive magnetic forces between the second magnetic component 68, the third magnetic component 70, and the first magnetic component 66 for driving the first rotary module 54 to rotate from the second position to the first position as shown in the bottom diagram of FIG. 5. When the first rotary module 54 is located in the first position, the pad 64 is exposed out of the first opening 58 on the housing 52 completely for supporting the LCD monitor. At this time, the end of the second magnetic component 68 close to the first magnetic component 66 is the S pole, the end of the first magnetic component 66 close to the second magnetic component 68 is the N pole, the end of the third magnetic component 70 close to the first magnetic component 66 is the N pole, and the end of the first magnetic component 66 close to the third magnetic component 70 is the S pole so that there are attractive magnetic forces between the second magnetic component 68, the third magnetic component 70, and the first magnetic component 66 for fixing the first rotary module 54 in the first position.
On the contrary, the first rotary module 54 needs to rotate from the first position to the second position when receiving the pad 64 in the first containing space 60 inside the housing 52. Please refer to FIG. 6. FIG. 6 is a diagram of the first rotary module 54 rotating from the first position to the second position according to the preferred embodiment of the present invention. When the switch 72 electrifies the second magnetic component 68 and the third magnetic component 70 with the first current direction, the magnetic fields of the second magnetic component 68 and the third magnetic component 70 convert again after being electrified with the first current direction opposite to the second current direction as shown in the middle diagram of FIG. 6. At this time, the end of the second magnetic component 68 close to the first magnetic component 66 is the N pole, and the end of the third magnetic component 70 close to the first magnetic component 66 is the S pole so that there are repulsive magnetic forces between the second magnetic component 68, the third magnetic component 70, and the first magnetic component 66 for driving the first rotary module 54 to rotate from the first position to the second position as shown in the bottom diagram of FIG. 6. At this time, the end of the second magnetic component 68 close to the first magnetic component 66 is the N pole, the end of the first magnetic component 66 close to the second magnetic component 68 is the S pole, the end of the third magnetic component 70 close to the first magnetic component 66 is the S pole, and the end of the first magnetic component 66 close to the third magnetic component 70 is the N pole so that there are attractive magnetic forces between the second magnetic component 68, the third magnetic component 70, and the first magnetic component 66 for fixing the first rotary module 54 in the second position.
Additionally, the switch 72 can be a button so that a user can press the button to switch current directions of the second magnetic component 68 and the third magnetic component 70. The switch 72 also can be linked to other mechanism or application. For example, the switch 72 can be actuated when opening/closing the LCD monitor, switching on or off the suspend mode, and so on. Any mechanism for switching current directions of the second magnetic component 68 and the third magnetic component 70 so as to convert magnetic fields of the second magnetic component 68 and the third magnetic component 70 is within the scope of the present invention.
Please refer to FIG. 7 and FIG. 8. FIG. 7 is an exploded drawing of the second rotary module 56 according to the preferred embodiment of the present invention. FIG. 8 is a sectional diagram of the second rotary module 56 installed inside the housing 52 according to the preferred embodiment of the present invention. A second opening 74 is formed on the housing 52, and a second containing space 76 is formed inside the housing 52. The second rotary module 56 can be disposed inside the second containing space 76 in a rotatable manner, such as being pivoted to the housing. The second rotary module 54 includes a bar 78 pivoted to the housing 52. The bar 78 can be a hollow bar for containing an electronic component. The bar 78 includes a first side 781 and a second side 782 opposite to the first side 781. The first side 781 can be an arc surface, and the second side 782 can be a plane. The second side 782 of the bar 78 and the surface 521 of the housing 52 can be made of same material and have same paint color so that the second side 782 of the bar 78 corresponds with the surface 521 of the housing 52 in an outward appearance. The second rotary module 56 further includes an electronic component 80 disposed on the first side 781 of the bar 78. The electronic component 80 can be an image capturing component, such as a camera, a speaker, an antenna, and so on. A first hole 82 is disposed on an end of the bar 78, and a second hole 84 is disposed on a side of the housing 52 corresponding to the first hole 82. A conducting wire of the electronic component 80 is capable of passing through the first hole 82 and the second hole 84 for connecting the electronic component 80 and other circuit inside the computer 50 electrically. The first hole 82 and the second hole 84 can be formed of arc shapes, such as a C-shaped hole so as to prevent interference between the conducting wire of the electronic component 80 and other structure when the second rotary module 56 rotates.
The electronic component 80 can be received inside the second containing space 76 by rotating the second rotary module 56 so as to provide protection and dust-proof functions for the electronic component 80 when not using the electronic component 80. At this time, the second side 782 of the bar 78 is level with the surface 521 of the housing 52 substantially. The second side 782 of the bar 78 and the surface 521 of the housing 52 can be made of same material and have same paint color, so the second side 782 of the bar 78 and the surface 521 of the housing 52 perform as an integrated body in the outward appearance. In addition, the electronic component 80 can be exposed out of the second opening 74 on the housing 52 by rotating the second rotary module 56 so as to perform functions of the electronic component 80, such as exposing a lens of a camera, a sound hole of a speaker, a receiving portion of an antenna, and so on. Both ends of the bar 78 of the second rotary module 56 are connected to the first magnetic components 66 respectively. The first magnetic component 66 can be glued to or welded with the bar 78. The second magnetic component 68 and the third magnetic component 70 are disposed on both sides of each first magnetic component 66. The first magnetic component 66 can be a permanent magnet and a circular structure. The second magnetic component 68 and the third magnetic component 70 can be electromagnets respectively having an iron core and copper enameled wires wound around the iron core. The working principle of the second rotary module 56 is the same as the working principle of the first rotary module 54, and hence a further description is hereby omitted.
In contrast with the prior art, the present invention utilizes magnetic forces to drive the rotary modules so as to switch the rotary modules in different positions for exposing a functional component when utilizing it or hiding the functional component for protection and the dust-proof function. The other side of the rotary module can be level with the surface of the housing and can be made of same material and have same paint color as the surface of the housing, so the rotary module and the surface of the housing perform as an integrated body in the outward appearance so as to increase aesthetic feeling of outward appearance.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
