The invention relates to a notebook computer, in particular to a notebook computer that can be turned on by turning on a display device.

Existing notebook computers often have a power button on the side of the host, and the user can press the power button to turn on the notebook computer.

Generally speaking, users often turn on the display device before pressing the power-on button, which causes the power-on process to be not concise and fast enough, and increases the user's waiting time.

The present invention is to provide a notebook computer, so as to solve the problem that the boot process of the notebook computer in the prior art is not concise and fast.

The notebook computer disclosed in an embodiment of the present invention includes a computer body and a power transmission device. The power transmission device has an opposite input terminal and an output terminal. The input terminal is used to electrically connect a power source. The output terminal is electrically connected to the computer body. The power transmission device includes an actuation circuit and a holding circuit. The actuation circuit is electrically connected between the input terminal and the output terminal. The holding circuit is connected in parallel to the actuation circuit.

According to the notebook computer disclosed in the above embodiment, when the notebook computer is unfolded, the actuating circuit will pass through and electrically connect the power supply and the computer body, so that the computer body can operate. In addition, after the circuit path is activated, the circuit path will be maintained. Once the activation circuit is broken, the computer body can still be electrically connected to the power supply through the retention circuit.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

An embodiment of the present invention will be described below. First, please refer to FIG. 1 to FIG. 2. FIG. 1 is a three-dimensional schematic diagram of a notebook computer according to an embodiment of the invention. FIG. 2 is a circuit diagram of the power transmission device of the notebook computer in FIG. 1.

The notebook computer 10 of this embodiment includes a computer body 100 and a power transmission device 200. The power transmission device 200 has an input terminal 201 and an output terminal 202 opposite to each other. The input terminal 201 is used to electrically connect a power source 20. The output terminal 202 is electrically connected to the computer body 100. The power transmission device 200 includes an actuation circuit 210 and a holding circuit 220. The actuation circuit 210 is electrically connected between the input terminal 201 and the output terminal 202, and is used to brake the holding circuit 220 when triggered. The holding circuit 220 is connected to the actuating circuit 210 in parallel, and once actuated by the actuating circuit 210, it can remain on when the actuating circuit 210 is powered off to maintain the operation of the power transmission device 200.

In detail, in this embodiment and some embodiments of the invention, the computer body 100 may further include a display 110, a host 120, and a rotating shaft 130. The rotating shaft 130 is connected between the display 110 and the host 120, and the display 110 is rotatably disposed on the host 120 through the rotating shaft 130. The actuating circuit 210 may further include a line switch 211 and a first light emitting diode 212. The line switch 211 is, for example, located in the shaft member 130. The line switch 211 is connected in series to the first light emitting diode 212 and is in an open circuit state. The first light emitting diode 212 has a first light emitting surface (not shown in the figure), and the first light emitting surface is used to emit light to the light-actuated switch 221. The holding circuit 220 can further include a light-actuated switch 221 and a second light emitting diode 222. The light-actuated switch 221 is connected to the second light emitting diode 222 in series and is in an off state. The second light emitting diode 222 has a second light emitting surface (not shown in the figure), and the second light emitting surface is also used to emit light to the light-actuated switch 221.

Then please refer to Figures 3 to 4. FIG. 3 is a three-dimensional schematic diagram of the display device of the notebook computer of FIG. 1 rotating and opening relative to the host. FIG. 4 is a circuit diagram of the power transmission device of the notebook computer of FIG. 3. When the display device 110 is turned on in a rotation direction R0 relative to the host 120, the line switch 211 will change from an open state to an open state, and the actuating circuit 210 is electrically connected to the power supply 20 and the computer body 100 to make the notebook computer 10 Turn on. The display device 110 rotates relative to the host 120 to turn on and causes the line switch 211 to be in the on state, which will be described later with FIGS. 7 to 8. When the line switch 211 is in the ON state, the first light-emitting diode 212 will emit light to the light-actuated switch 221 along a first path R1 through the first light-emitting surface. After receiving the light source, the light-actuated switch 221 will change from an off state to a pass state, and the second light-emitting diode 222 will emit light to the light-actuated switch 221 along a second path R2 through the second light-emitting surface. The first light-emitting surface 2121 or the second light-emitting surface 2221 preferably faces the light-actuated switch 221, but this is not intended to limit the present invention. In some embodiments, the first light-emitting surface or the second light-emitting surface may face a reflector and emit light from the reflector to direct light toward the light-actuated switch.

Please refer to Figure 1 and Figure 5. FIG. 5 is a circuit diagram of the holding circuit of the notebook computer of FIG. 1 in a pass state. When the display device 110 is closed to the host 120, the line switch 211 will change from the on state back to the off state and the first light-emitting diode 212 no longer emits light. At this time, the second light-emitting diode 222 still emits light on the light-actuated switch 221, so that the light-actuated switch 221 remains in the on state. Therefore, even if the display device 110 is closed to the host 120, the computer body 100 can still be electrically connected to the power source 20 through the holding circuit 220 and keep the notebook computer 10 operating.

Then please refer to Figures 5 to 6. FIG. 6 is a circuit diagram of the normally closed switch of the notebook computer of FIG. 1 in an open state. In this embodiment and some embodiments of the present invention, the notebook computer 10 may further include a normally closed switch 300. As shown in FIG. 5, the normally closed switch 300 is in a path state and is connected to the input terminal 201. The input terminal 201 is electrically connected to the power source 20 through the normally closed switch 300. When the user wants to shut down the notebook computer 10, the normally closed switch 300 is pressed through, for example, a top member (not shown in the figure) and the normally closed switch 300 is in an open state, as shown in FIG. 6. After the normally closed switch 300 is in the open state, the second light emitting diode 222 no longer emits light, and the light-actuated switch 221 is in the open state. Therefore, when the abutment member is separated from the normally closed switch 300, the normally closed switch 300 is in a closed state and the power transmission device 200 returns to the state shown in FIG. 2.

In summary, the notebook computer 10 turns on the display device 110 by rotating it so that the computer body 100 is electrically connected to the power supply 20 through the power transmission device 200 to achieve a simple and fast booting process. The circuit diagram is shown in FIG. 4. Then, after the display device 110 is closed, the power transmission device 200 can still maintain the on-state, and the power source 20 can continue to supply power to the computer body 100. The circuit diagram is shown in FIG. 5. In addition, when the user shuts down the notebook computer 10 through the programming interface, the normally closed switch 300 changes from the on state to the off state so that the computer body 100 is not electrically connected to the power source 20 and the notebook computer 10 is shut down. The circuit diagram is as The state shown in Figure 6. Finally, when the abutment member is separated from the normally closed switch 300, the normally closed switch 300 is in a closed state and the circuit diagram is in the state shown in FIG. 2.

Then please refer to Figures 1 to 5 and Figures 7 to 8. FIG. 7 is a schematic diagram of the line switch of the power transmission device of FIG. 2 in an open state. Fig. 8 is a schematic diagram of the circuit switch of Fig. 4 in an on state. In this embodiment and some embodiments of the present invention, the line switch 211 may further include a first part 2110 and a second part 2111 opposite to each other. The first part 2110 is connected to the display 110. The second component 2111 is connected to the host 120. The first component 2110 may further have a first insulating end 2112 and a first energizing end 2113. The second component 2111 may further have a second insulating end 2114 and a second energizing end 2115. The first insulating end 2112 is connected to the second insulating end 2114. As shown in FIG. 1, when the display device 110 is closed to the host 120, the circuit diagram is as in the state of FIG. 2 and the mechanism state of the line switch 211 is as shown in FIG. Since the first energized terminal 2113 is not connected to the second energized terminal 2115, the line switch 211 is in a disconnected state.

As shown in FIG. 3, when the display 110 is turned on in the rotation direction R0 relative to the host 120 and an intersection angle A between the display 110 and the host 120 is within a power range of 5° to 150°, the first power-on terminal 2113 follows the display 110 rotates, causing the first energizing terminal 2113 to contact and electrically connect to the second energizing terminal 2115, such as the line switch 211 shown in FIG. 8, and the line switch 211 is in a state of conduction, and the circuit diagram is as the state of FIG. When the display 110 is closed to the host 120 in the state shown in Figure 1, the intersection angle A is outside the energized range, the first energized terminal 2113 is separated from the second energized terminal 2115, as shown in Figure 7, and the line switch 211 is in an open state, the circuit diagram is as The state of Figure 5 above. The procedure for the user to shut down the notebook computer 10 is as described above, and will not be repeated here.

The method in which the line switch 211 uses the first component 2110 and the second component 2111 to connect the display 110 and the host 120 to achieve the above functions is not intended to limit the present invention. Please refer to Figure 1, Figure 3, Figure 9 and Figure 10. FIG. 9 is a schematic diagram of a line switch of a notebook computer in an open state according to another embodiment of the present invention. Fig. 10 is a schematic diagram of the circuit switch of Fig. 9 in an on state. In this embodiment and some embodiments of the present invention, the line switch 211 may further include a switch body 2116 and a magnetic element 2117. As shown in FIG. 9, a distance D is maintained between the switch body 2116 and the magnetic member 2117. The switch body 2116 is connected to the host 120, and the magnetic member 2117 is connected to the display 110, but not limited to this. In other embodiments, the switch body is connected to the display, and the magnetic part is connected to the host. In this embodiment and some embodiments of the present invention, the switch body 2116 may further include a movable part 2118 and a fixed part 2119. An elastic tension of the movable part 2118 is greater than a magnetic attraction force of the magnetic part 2117 to the movable part 2118. Therefore, the switch body 2116 is not affected by the magnetic member 2117 and is in a disconnected state.

As shown in FIG. 3, when the display 110 is turned on in the rotation direction R0 relative to the host 120 and the intersecting angle A between the display 110 and the host 120 is within the energization range of 5° to 150°, the magnetic member 2117 rotates along with the display 110. Close to the movable part 2118, the distance between the switch body 2116 and the magnetic part 2117 is transformed into a distance D', so that the magnetic attraction force of the magnetic part 2117 on the movable part 2118 is greater than the elastic tension of the movable part 2118, and the movable part 2118 is attracted by the magnetic part 2117 and then touches. The fixing member 2119 is electrically connected, and the circuit switch 211 is in a state of a circuit, as shown in FIG. 10. When the display 110 is closed to the host 120 and the user wants to shut down the notebook computer 10, the process is similar to the foregoing, and will not be repeated here.

According to the notebook computer of the aforementioned embodiment, turning on the display device allows the computer body to be electrically connected to the power source through the power transmission device to achieve a simple and fast boot process. Then, after the display device is closed, the power supply transmission device can still maintain the connection state, and the power supply can continue to supply power to the computer body. In addition, when the user shuts down the notebook computer through the programming interface, the normally closed switch changes from the on state to the off state so that the computer body is not electrically connected to the power source and the notebook computer is shut down. Finally, when the abutment piece is separated from the normally closed switch, the normally closed switch assumes a path state.

In some embodiments, the line switch may further include a first component and a second component opposite to each other. When the display is turned on relative to the host and the intersection angle between the display and the host is within the energized range, the first energized end rotates with the display, causing the first energizing end to contact and electrically connect to the second energizing end, and the circuit switch is in a path status. When the display is closed to the host, the intersection angle is outside the energized range, the first energized end is separated from the second energized end, and the line switch is in an open circuit state.

In some embodiments, the line switch may further include a switch body and a magnetic element. When the display rotates relative to the host and the intersection angle between the display and the host is within the energized range, the magnetic part rotates with the display and approaches the movable part, causing the magnetic attraction of the magnetic part to the movable part to be greater than the elastic tension of the movable part. After being attracted by the magnetic member, it contacts and is electrically connected to the fixing member, and the circuit switch is in a state of a circuit.

Although the present invention is disclosed in the foregoing embodiments as above, it is not intended to limit the present invention. Anyone familiar with similar art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of patent protection for inventions shall be determined by the scope of patent applications attached to this specification.
