In order to provide more functions and improve the operational convenience of the electronic device, the electronic device can be connected to the docking station in a forward insertion and reverse insertion manner to provide a corresponding working mode. 1A to 1C are schematic views of an electronic component. Referring to FIG. 1A and FIG. 1A, when the electronic device 11 is assembled on the susceptor 12, the connection interfaces 11a, 12a are connected for power transmission or data transmission. Depending on the assembly direction, the electronic device 11 can be connected to the susceptor 12 in a reverse insertion manner (as shown in FIG. 1A), and the electronic device 11 can also be connected to the susceptor 12 in a forward insertion manner (as shown in FIG. 1B). ). That is to say, the arrangement of the pins of the connection interfaces 11a, 12a must be designed so that the electronic device 11 can be connected to the susceptor 12 in different insertion directions.

However, when the electronic device 11 is inserted into the susceptor 12 and the electronic device 11 and the susceptor 12 are in a closed state (as shown in FIG. 1C), the electronic device 11 enters a power saving state to save power consumption. In this case, once the electronic device 11 or the susceptor 12 is strongly pressed by an external force, the electronic device 11 may be caused to accidentally touch the peripheral input device on the susceptor 12. If the electronic device 11 is awakened from the power saving state to the active state because the peripheral input device on the susceptor 12 is accidentally touched, not only unnecessary power consumption but also an operation result unexpected to the user may be generated.

The novel creation provides a base, an electronic device and a composite device, which can further determine whether to disable the peripheral input device according to the closed state of the electronic device and the base, so as to prevent the electronic device from being mistaken because the peripheral input device on the base is mistaken.

The controller is coupled to the power supply unit and the second function pin. After the controller determines that the electronic device is in the positive insertion state according to the level of the second function pin, the controller continuously detects the level of the second function pin to determine whether to disable the periphery according to the level of the second function pin. Input device.

The first end of the switch unit is coupled to the first voltage, and the second end of the switch unit is coupled to the status notification pin. The processor is coupled to the status notification pin and the closed sensing element. After the processor determines that the electronic device is in the positive insertion state according to the level of the status notification pin, the processor determines whether to turn on the switch unit according to whether the closed event signal is received, so that the level of the status notification pin is responsive to the switch unit. Turn on and pull up to a high level.

The first function pin is connected to one of the status notification pin and the power supply pin, and the second function pin is connected to the status notification pin and the power supply pin. The controller is coupled to the second function pin. After the processor determines that the electronic device is in the positive insertion state according to the level of the status notification pin, the processor determines whether to turn on the switch unit according to whether the closed event signal is received, so as to cause the level response of the second function pin of the base. Pulling up to a high level on the conduction of the switching unit. When the closed sensing element detects that the electronic device and the base are in a closed state, the closed sensing element emits a closed event signal.

2 is a schematic diagram of a composite device according to an embodiment of the present invention. Referring to FIG. 2, the composite device of the embodiment includes an electronic device 30 and a base 20. The electronic device 30 is, for example, a portable electronic device such as a tablet computer or a smart phone. The susceptor 20 may have a device such as a keyboard or a speaker and other peripheral expansion devices, and the type thereof is not limited herein. It should be noted that the example shown in FIG. 2 is that the electronic device 30 is connected to the susceptor 20 in a forward insertion manner. The electronic device 30 includes a closed sensing component 310, a processor 320, a switch unit 330, and a device connection interface I1, and is adapted to be connected to the base 20 through the device connection interface I1. The closed sensing unit 310 is, for example, a proximity sensor, a capacitive sensor, an infrared sensor, or a magnetic sensor, and detects that the electronic device 30 and the base 20 are in a closed state or an open state. When the electronic device 30 and the susceptor 20 are in a closed state, the normal direction of the screen of the electronic device 30 is substantially parallel to the normal direction of the operable surface of the susceptor 20, and the screen of the electronic device 30 covers the pedestal 20 Above the operable surface. In detail, the closed sensing component 310 detects whether the electronic device 30 and the susceptor 20 are in a closed state. When the closed sensing component 310 detects that the electronic device 30 and the susceptor 20 are in a closed state, the closed sensing component 310 emits a closed event signal S3.

The processor 320 can be a central processing unit (CPU), an embedded controller, or other programmable general purpose or special purpose microprocessor (Microprocessor). The switch unit 330 can be a switch, a multiplexer, a logic circuit, or an element composed of a combination thereof, and the present invention is not limited thereto.

The susceptor 20 includes a pedestal connection interface I2, a power supply unit 210, a controller 220, and a peripheral input device 230. The peripheral input device 230 can be an input device such as a keyboard, a touch pad or a function button, and is one of the control media for the user to control the electronic device. The device connection interface I1 and the base connection interface I2 each have a pin row including a plurality of pins, and the number of pins of the device connection interface I1 is the same as the number of pins of the base connection interface I2. Furthermore, when the pedestal is connected to the device connection interface I1 of the electronic device 30 through the pedestal connection interface I2, the pins of the device connection interface I1 and the pins of the pedestal connection interface I2 are electrically connected to each other. For example, when the pedestal is connected to the device connection interface I1 of the electronic device 30 through the pedestal connection interface I2, the electronic device 30 can supply power to the susceptor 20 through a specific pin to drive the pedestal 20 to start normal operation.

In this embodiment, the pedestal connection interface I2 includes a first function pin PD1 and a second function pin PD2, and the first function pin PD1 and the second function pin PD2 are connected to the center line L1 of the interface I2. Symmetrically set for the center of symmetry. In other words, sorting outward from the center line L1, the pins of the first function pin PD1 are aligned and the pins of the second function pin PD2 are aligned. In addition, the device connection interface I1 includes a power supply pin PWR coupled to the first voltage V1 and a state notification pin DET1, and the power supply pin PWR and the state notification pin DET1 are centered on the center line L1 of the device connection interface I1. And symmetric settings. In the embodiment shown in FIG. 2A, since the susceptor 20 is connected to the electronic device 30 in a forward insertion manner, the power supply pin PWR is connected to the first function pin PD1, and the state notification pin DET1 is connected to the second. Function pin PD2. However, the novel creation does not limit the definition and arrangement of the device connection interface I1 and other pins on the pedestal connection interface I2. For example, the device connection interface I1 and the cradle connection interface I2 have corresponding data transmission pins based on the data convergence standards of the two parties, and the data transmission pins can be arranged on the first function pin PD1 and the second function connection. Between the feet PD2, but the novel creation is not limited to this.

The power supply unit 210 is coupled to the first function pin PD1 and the second function pin PD2. As shown in FIG. 2, when the susceptor 20 is connected to the electronic device 30 in a forward insertion manner, the power supply unit 210 can receive the first voltage V1 provided by the electronic device 30 through the first function pin PD1, and respond to the receiving. The first voltage V1 outputs a supply signal Vcc. However, although not shown in FIG. 2, those skilled in the art should readily infer that when the susceptor 20 is connected to the electronic device 30 in a reverse insertion manner, the power supply unit 210 can receive the electronic device through the second functional pin PD2. The first voltage V1 is provided by 30, and the supply signal Vcc is output in response to receiving the first voltage V1.

The controller 220 is coupled to the power supply unit 210 and the second function pin PD2. The controller 220 determines that the electronic device 30 is in the forward insertion state or the reverse insertion state according to the level of the second function pin PD2 in response to receiving the supply signal Vcc. The positive insertion state and the reverse insertion state are connected to the susceptor 20 in different directions of the electronic device 30, respectively. In this embodiment, when the susceptor 20 is connected to the electronic device 30 in a forward insertion manner, the level of the second function pin PD2 is at a low level, and the controller 220 can determine that the electronic device 30 is positive. Plug in state. On the other hand, although not shown in FIG. 2, those skilled in the art should easily infer that when the susceptor 20 is connected to the electronic device 30 in a reverse insertion manner, the level of the second functional pin PD2 is high. The controller 220 can determine that the electronic device 30 is in the reverse insertion state. In addition, in an embodiment of the present invention, since the status notification pin DET1 can be connected to the first function pin PD1 or the second function pin PD1, the electronic device 30 can also notify the pin DET1 according to the status. The position is known as the direction of connection between the electronic device 30 and the base 20.

It should be noted that when the controller 220 determines that the electronic device 30 is in the reverse insertion state, the controller 220 disables the peripheral input device 230. When the controller 220 determines that the electronic device 30 is in the forward insertion state, the controller 220 enables the peripheral input device 230. In addition, after the processor 320 determines that the electronic device 30 is in the positive insertion state according to the level of the status notification pin DET1, the processor 320 determines whether to turn on the switch unit 330 according to whether the closed event signal S3 is received, so that the status notification pin is enabled. The level of DET1 is pulled up to a high level in response to the conduction of the switching unit 330.

On the other hand, after the controller 220 determines that the electronic device 30 is in the positive insertion state according to the level of the second function pin PD2, the controller 220 continuously detects the level of the second function pin PD2 to perform the second function according to the second function. The level of the pin PD2 determines whether the peripheral input device 230 is disabled. Further, when the processor 320 receives the closed event signal S3 and the level of the state notification pin DET1 is pulled up to the high level in response to the conduction of the switch unit 330, the connection state notifies the second function of the pin DET1. The pin PD2 is also pulled up to a high level, and the controller 220 disables the peripheral input device 230 in response to the second function pin PD2 being pulled up to a high level.

As such, when the electronic device 30 is connected to the susceptor 20 in a forward insertion manner and the electronic device 30 and the susceptor 20 are in a closed state, the peripheral input device 230 can be disabled by the controller 220. For example, FIG. 3 is a schematic diagram of an example of a composite device according to an embodiment of the present invention. It is assumed that the closed sensing element 310 is a magnetic member sensor and the base 20 includes a magnetic element 240. Referring to FIG. 3, the closed sensing element 310 is disposed at the upper left corner of the screen 340 of the electronic device 30, and the magnetic element 240 is disposed at the lower left corner of the keyboard 230a. Therefore, when the user picks up the electronic device 30, the closed sensing element 310 can issue a closed event signal S3 due to the proximity of the magnetic element 240.

4A and 4B are schematic views of a composite device according to another embodiment of the present invention. It should be noted that, in this embodiment, the device connection interface and the cradle connection interface support the third generation universal serial bus standard (Universal Serial Bus 3.0, USB 3.0) as an example, but the novel creation does not limit. In another embodiment, the device connection interface and the cradle connection interface also support the second generation universal serial bus standard (USB 2.0). Referring first to FIG. 4A, the electronic device 40 is adapted to be coupled to the pedestal connection interface I4 of the susceptor 50 via the device connection interface I3. In the embodiment illustrated in FIG. 4A, electronic device 40 is coupled to pedestal 50 in a forward insertion manner. The electronic device 40 includes a processor 410, a voltage dividing unit 420, a pull-up unit 430, a closed sensing element 440, a switching unit SW1, a switching unit SW2, and a device connection interface I3.

The device connection interface I3 includes a transmit/receive data pin D+/D-, a power supply pin PWR, a status notification pin DET1, a receive differential signal pin RX+/RX-, and a differential signal pin TX+/TX-, The pedestal detection pin DET0 and the ground pin GND, wherein the alignment of each pin is as shown in FIG. 3A. The pull-up unit 430 includes a resistor R1 and is coupled between the base detecting pin DET0 and the detecting voltage V2, and outputs a detecting signal Sd. The first end of the switch unit SW1 is coupled to the first voltage V1, and the second end of the switch unit SW1 is coupled to the power supply pin PWR. The processor 410 is coupled to the base detecting pin DET0 to receive the detecting signal Sd. The voltage dividing unit 420 includes a resistor R2 and a resistor R3 coupled between the ground voltage and the state notification pin DET1 to provide the voltage division detecting signal S1 to the processor 410 according to the level of the state notification pin DET1. The closed sensing element 440 is coupled to the processor 410 and outputs a closed event signal S3 to the processor 410 when the electronic device 40 and the base 50 assume a closed state. When the processor 410 receives the closed event signal S3, the switch unit SW2 is turned on.

The susceptor 50 includes a susceptor connection interface I4, a power supply unit 510, a controller 520, a voltage dividing unit 530, an operation input unit 540, and a diode D1. The cradle connection interface I4 includes first/second data pins D1/D2, first/second function pins PD1/PD2, differential signal pins TR1/TR2, differential signal pins TR3/TR4, first /Second ground pin GND1/GND2. The first/second ground pins GND1/GND2 are symmetrically arranged with the center line L2 as a center of symmetry.

The anode end of the diode D1 is coupled to the second function pin PD2, and the cathode end of the diode D1 is coupled to the power supply unit 510. The voltage dividing unit 530 includes a resistor R4 and a resistor R5, and is coupled between the second function pin PD2 and the ground voltage, and provides a voltage dividing detection signal S2 to the controller 520 according to the level of the second function pin PD2. . In the embodiment shown in FIG. 4A, when the electronic device 40 and the susceptor 20 are connected to each other in a forward manner, the connection manner of each of the pins is as shown in FIG. 3A. For example, the first function pin PD1 is connected to the power supply pin PWR, and the second function pin PD2 is connected to the status notification pin DET1. When the level of the detection signal Sd is pulled down to the low level because the pedestal detection pin DET0 is connected to the pedestal 50, the switch unit SW1 is delayed in response to the level of the detection signal Sd being pulled down to the low level. Turn on after time. When the switch unit SW1 is turned on, the first voltage V1 is outputted to the first function pin PD1 of the susceptor 20 via the power supply pin, so that the power supply unit 510 receives the first voltage V1 through the first function pin PD1.

The power supply unit 510 outputs the supply signal Vcc to the controller 520 in response to receiving the first voltage V1, and the diode D1 is turned off. Therefore, the level of the second function pin PD2 is maintained at a low level, and the voltage division detecting signal S2 generated by the voltage dividing unit 530 according to the level of the second function pin PD2 is maintained at a low level. Since the voltage division detection signal S2 is at a low level, the controller 520 can determine that the electronic device 40 is in the positive insertion state. When the controller 520 determines that the electronic device 40 is in the positive insertion state, the controller 520 enables the peripheral input device 540 of the base 50.

In addition, since the status notification pin DET1 is connected to the second function pin PD2, the level of the status notification pin DET1 is also a low level. The voltage dividing detection signal S1 output by the voltage dividing unit 420 according to the state notification pin DET1 is also a low level. Therefore, the processor 410 can also determine that the electronic device 40 is in the positive insertion state. During the period when the electronic device 40 is determined to be in the forward insertion state, the processor 410 determines to turn on the switch unit SW2 according to the reception of the closed event signal S3. When the switch unit SW2 is turned on, the state of the pin DET1 is pulled up to the high level and the level of the second function pin PD2 is also pulled up to the high level. In this manner, the controller 520 can disable the peripheral input device 540 according to the voltage division detection signal S2 that is pulled up to the high level.

Referring to FIG. 4B again, the electronic device and the cradle in FIG. 4B are the same as the electronic device and the pedestal in FIG. 3A. However, in the embodiment shown in FIG. 4B, the electronic device 40 is coupled to the base 50 in a reverse insertion manner. Similarly, when the first ground pin GND1 is connected to the pedestal detecting pin DET0, the switching unit SW1 is delayed in conduction and the first voltage V1 is outputted to the second function pin PD2 of the susceptor 20 via the power supply pin. The diode D2 is thus turned on by receiving the first voltage V1, so that the power supply unit 510 receives the first voltage V1 through the second function pin PD2. Therefore, the level of the second function pin PD2, the voltage division detection signal S2, and the level of the first function pin PD1 are maintained at a high level. In this manner, the controller 520 can determine that the electronic device 50 is in the reverse insertion state according to the high-level partial pressure detection signal S2, and disable the peripheral input device 540. At the same time, the level of the status notification pin DET1 and the voltage division detection signal S1 are also at a high level, and the processor 410 can also determine that the electronic device 40 is in the reverse insertion state. In addition, since the electronic device 40 is in a reversed state with the susceptor 50, the closed sensing element 440 does not emit a closed event signal, and the switching unit SW2 remains in a non-conductive state.

FIG. 5 is a flow chart of determining an operation mode of an electronic device according to an embodiment of the present invention. Referring to FIG. 5, in step S501, an electronic device and a base are provided, and the electronic device is adapted to be connected to the base. In step S502, it is determined whether the level of the pedestal detecting pin is a low level. If the determination in step S502 is NO, in step S503, the electronic device is set to the first tablet operation mode that is not connected to the cradle. If the determination in step S502 is YES, in step S504, the switch unit connected to the power supply pin of the electronic device is turned on, so that the first voltage is transmitted to the power supply unit of the susceptor. In step S505, it is determined whether the state of the electronic device notification pin is the same as the second function pin of the pedestal. If the determination in step S505 is YES, in step S506, the electronic device is set to the second tablet operation mode connected to the base. In step S507, the peripheral input device of the electronic device is disabled. If the determination in step S505 is NO, the electronic device is set to the notebook operation mode in step S508. In step S509, it is continuously detected whether a closed event signal is received. In step S510, the switch unit connected to the status notification pin of the electronic device is turned on, so that the level of the status notification pin is pulled up to the high level. In step S511, the peripheral input device of the electronic device is disabled.

In summary, in the cradle, the electronic device, and the composite device proposed in the novel creation embodiment, after the electronic device determines that it is connected to the pedestal in a forward insertion manner, the electronic device and the base may be further Whether the seat assumes a closed state to control a switch unit connected to the status notification pin, so that the level of the second multi-function pin connected to the status notification pin depends on the conduction state of the switch unit. Thereby, not only the function of bidirectional connection between the susceptor and the electronic device can be realized, but also the malfunction of the electronic device and the susceptor in the closed state due to accidental contact with the peripheral input device can be avoided.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation.
