Embodiment
First embodiment
Please be simultaneously with reference to Figure 1A and Figure 1B, Figure 1A illustrates the functional block diagram according to the input element switcher of first embodiment of the invention, and Figure 1B illustrates the outside drawing of the input element switcher of present embodiment.Shown in Figure 1A, input element switcher 200 comprises a first housing 202 (being shown in Figure 1B), one first connectivity port 204, one first signal switch unit 206, a processing unit 208 and one the 3rd connectivity port 210.First signal switch unit 206 electrically connects one first main frame 102 and one second main frame 104.Processing unit 208 can for example be set the table (not shown) according to a hot key, supplies input element 110 to switch to the main frame of desire operation, for example is first main frame 102 or second main frame 104.The 3rd connectivity port 210 is arranged at the first housing 202 and in order to electrically connect input element 110 (for example being keyboard and/or mouse).The 3rd connectivity port 210 is a PS/2 joint or a USB (Universal Serial Bus, USB) joint.The electricity consumption of input element switcher 200 can be after itself and main frame electrically connect; For example be after input element switcher 200 electrically connects with USB interface and main frame; Supply power to input element switcher 200 by main frame; In addition also can be directly through outside independent current source power supply, perhaps input element switcher 200 itself can load battery (not shown) power supply.
In addition, input element switcher 200 also can switch to the main frame of desire operation through the switch bar (not shown) of being located at the first housing 202.
Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, Fig. 2 A illustrates the functional block diagram according to the screen switcher of present embodiment of the present invention, and Fig. 2 B illustrates the outside drawing of the screen switcher of present embodiment.Shown in Fig. 2 A, screen switcher 300 comprises a second housing 302 (being shown in Fig. 2 B), a secondary signal switch unit 306, one the 4th connectivity port 310 and one second connectivity port 304.Secondary signal switch unit 306 electrically connects one the 3rd main frame 106 and one the 4th main frame 108, and in order to switch signal, supply screen 112 to switch to desire and show main frame according to one of switching device 308, for example be the 3rd main frame 106 or the 4th main frame 108.The 4th connectivity port 310 is arranged at the second housing 302 and can for example is a VGA joint or a HDMI joint in order to electrically connect screen 112, the four connectivity ports 310.And second connectivity port 304 is in order to electrically connect with first connectivity port 204.
Shown in Fig. 2 B, the switching device 308 of present embodiment is to electrically connect with an electric wire 312 and the second housing 302, in order to screen 112 is switched to the 3rd main frame 106 or the 4th main frame 108.Yet in other embodiments, switching device 308 also can be arranged on the second housing 302, does not need to pull out connection with electric wire 312 in addition.In addition, the electricity consumption of screen switcher 300 can be electrically connected to an independent current source (not shown) or a main frame through a connecting line (not shown), then by independent current source or main frame power supply.And an end of connecting line for example can be connected in second connectivity port, and its other end then is connected in independent current source or main frame.Perhaps, screen switcher 300 itself can load a battery (not shown).When screen switcher 300 uses separately, supply power by above-mentioned independent current source, main frame or battery.
Please with reference to Fig. 3 A and Fig. 3 B, the synoptic diagram that is connected of the input element switcher that Fig. 3 A illustrates Figure 1B and the screen switcher of Fig. 2 B, Fig. 3 B illustrates the functional block diagram of the multi-computer switching device of Fig. 3 A.Shown in Fig. 3 A, through the electric connection of first connectivity port 204 and second connectivity port 304, input element switcher 200 becomes a multi-computer switching device 100 with screen switcher 300.In addition, first connectivity port 204 is connected except the effect that electric connection is arranged with second connectivity port 304, and affixed effect is also arranged, and the connectivity port 204 of winning more can not broken away from second connectivity port 304 easily and causes electrically and separates.
When input element switcher 200 and screen switcher 300 be formed by connecting be a multi-computer switching device 100 after, whole multi-computer switching device 100 can be supplied power by main frame.For instance, main frame and input element switcher 200 can electrically connect through the USB interface, and main frame is supplied power to multi-computer switching device 100 through this USB interface.In addition also can be through outside independent current source power supply.
In addition; When input element switcher 200 and screen switcher 300 are electrically connected and after becoming multi-computer switching device 100; The processing unit 208 of input element switcher 200 can be set table according to another hot key; With input element 110 and screen 112 simultaneously or distinctly switch to identical or different main frame, for example be first main frame 102, second main frame 104, the 3rd main frame 106 or the 4th main frame 108.Wherein, hot key setting table can be stored in the processing unit 208 of input element switcher 200, and the user can accomplish the action of input hot key through input element 110.
In addition, the switching mode of multi-computer switching device 100 also can be reached by switching device 308.For example, be electrically connected and after becoming multi-computer switching device 100, operation switching device 308 just can or distinctly switch to identical or different main frame with input element 110 and 112 whiles of screen when input element switcher 200 and screen switcher 300.Switch bar (not shown) that also maybe can be through being located at the first housing 202 with input element 110 and screen 112 simultaneously or distinctly switch to identical or different main frame.
Therefore; The input element switcher 200 of present embodiment and screen switcher 300 are except can independently individually operating; Be electrically connected to each other become multi-computer switching device 100 together after; Hot key capable of using or operation switching device 308, with input element 110 and screen 112 simultaneously or distinctly switch to identical or different main frame.
In addition, the input element switcher 200 of the separate type of present embodiment and screen switcher 300 still have the advantage of the purchase cost that reduces the user.For instance, upgrade screen 112 when user's desire is superseded, and the joint of the new screen of buying is the HDMI pattern.If this moment screen switcher 300 the 4th connectivity port 310 non-be the HDMI pattern, then, need not change whole multi-computer switching device 100, so reduce the renewal cost of equipment as long as change screen switcher 300.
In addition; Though the input element switcher 200 of present embodiment and screen switcher 300 are by first connectivity port 204 and second connectivity port, 304 direct docking modes; Yet also can electrically connect between first connectivity port and second connectivity port in other embodiments, through cable.So, input element switcher 200 just need not be limited in same position with the placement location of screen switcher 300, has promoted the elasticity of track laying.
