[0048] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Combine the following Figure 1-Figure 9 , the first electronic device and the electronic device component provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0050] In the first aspect, Figure 1 As shown, an embodiment of the utility model provides a first electronic device 1, comprising: a first processing module 11, a first acquisition circuit 12, a first power supply module 13, a switch control circuit 15 and a first adapter 16.

[0051] The first processing module 11 is communicatively connected to the first adapter 16 through the first acquisition circuit 12, the first power supply module 13 and the first processing module 11 are electrically connected to the switch control circuit 15 respectively, the switch control circuit 15 is electrically connected to the first adapter 16, and the first adapter 16 is configured to be electrically connected to the second adapter 26 on the second electronic device 2.

[0052] The first acquisition circuit 12 is further used to acquire a voltage signal on the second adapter 26 , and the first processing module 11 is used to control the switch state of the switch control circuit 15 according to the voltage signal fed back by the first acquisition circuit 12 .

[0053] It is understandable that the first electronic device 1 includes a first housing, a first control board 101 disposed on the first housing, and an LCD screen 18. The first processing module 11, the first acquisition circuit 12, the switch control circuit 15 and the first adapter 16 can be disposed on the first control board 101 respectively.

[0054] The first power module 13 may be a lithium battery module known in the art, the first processing module 11 may be a central processing unit (CPU), and the first processing module 11 is communicatively connected to the LCD screen 18 .

[0055] The first control board 101 is provided with a Host interface, the first processing module 11 and the first acquisition circuit 12 are electrically connected to the Host interface respectively, and the Host interface is electrically connected to the first transfer interface 16 .

[0056] The first transfer interface 16 is configured with at least three connection channels, the first of which is used to establish a communication connection with the first processing module 11, the second of which is used to electrically connect to the switch control circuit 15, and the third of which is used to electrically connect to the first acquisition circuit 12 to transmit the voltage signal collected on the second transfer interface 26. The voltage signal collected on the second transfer interface 26 is usually a power-on signal of the second electronic device.

[0057] The first acquisition circuit 12 can use a board-to-board connector to realize the transmission of communication signals between the first processing module 11 and the first adapter 16, and the first acquisition circuit 12 is also used to collect voltage signals on the second adapter 26 and feed the collected voltage signals back to the first processing module 11.

[0058] The switch control circuit 15 can be constructed using switching devices such as transistors and MOS tubes, so that the first processing module 11 can control the switch state of the switch control circuit 15 according to the voltage signal fed back by the first acquisition circuit 12 .

[0059] Among them, when the first electronic device 1 is not turned on, the first acquisition circuit 12 cannot collect any voltage signal, or the voltage signal collected by the first acquisition circuit 12 is at a low level (for example, 0V). At this time, the first processing module 11 does not send a control instruction to the switch control circuit 15, and the switch control circuit 15 is in an open circuit state.

[0060] When the first electronic device 1 is turned on, the first acquisition circuit 12 can acquire a voltage signal, and the voltage signal is a fixed voltage value greater than zero. At this time, the first processing module 11 sends a control instruction to the switch control circuit 15, and the switch control circuit 15 is in the on state.

[0061] For the first electronic device 1 shown in this embodiment, by configuring the first electronic device 1 with a first processing module 11, a first acquisition circuit 12, a first power module 13, a switch control circuit 15 and a first adapter 16, the first processing module 11 can be communicatively connected with the first adapter 16 through the first acquisition circuit 12, and then establish a communication connection with the second adapter 26 on the second electronic device 2 based on the first adapter 16, so as to realize the information interaction between the first electronic device 1 and the second electronic device 2; at the same time, since the first acquisition circuit 12 and the first adapter 16 are electrically connected, and the first adapter 16 and the second adapter 26 are electrically connected, the first acquisition circuit 12 can collect the voltage signal on the second adapter 26, and the first processing module 11 can determine whether the second electronic device 2 is in the power-on state according to the voltage signal, and when it is determined that the second electronic device 2 is powered on, the switch control circuit 15 is controlled to be in the on state, so that the first power module 13 charges the second electronic device 2 through the link circuit established by the first adapter 16 and the second adapter 26.

[0062] It can be seen from the above that the first electronic device 1 shown in the present invention can meet the communication requirements between the first electronic device 1 and the second electronic device 2 while also being able to reliably charge the second electronic device 2 .

[0063] In some embodiments, the first adapter 16 and the second adapter 26 are adapted and both are configured as Pogopin interfaces.

[0064] Since the Pogopin interface is configured with multiple contacts, this design facilitates the allocation of the type of electrical signal transmission through the various contacts of the Pogopin interface, ensuring that the first adapter 16 and the second adapter 26 can transmit not only communication signals, but also charging signals and voltage acquisition signals.

[0065] Furthermore, the Pogopin interface includes: a power contact, a communication contact, a ground contact and an ID contact; wherein the power contact, the communication contact, the ground contact and the ID contact are arranged side by side, and at least two communication contacts are arranged.

[0066] The first processing module 11 is electrically connected to the communication contact, the first acquisition circuit 12 is electrically connected to the ID contact, the switch control circuit 15 is electrically connected to the power contact, and the grounding module on the first electronic device 1 is electrically connected to the grounding contact.

[0067] like Figure 2 As shown, the first acquisition circuit 12 is configured with three connection terminals, namely, a USB1_DP terminal, a USB1_DM terminal and a COMM_INT terminal, and the USB1_DP terminal, the USB1_DM terminal and the COMM_INT terminal are respectively connected to the first processing module 11 through a BTB connector.

[0068] Among them, the USB1_DP terminal and the USB1_DM terminal are used as communication terminals and are electrically connected to the two communication contacts on the Pogopin interface respectively; the COMM_INT terminal is used as a signal acquisition terminal and is electrically connected to the ID contact on the Pogopin interface.

[0069] At the same time, any of the USB1_DP terminal, USB1_DM terminal and COMM_INT terminal is grounded through a voltage regulator to ensure the stability of the signal on each terminal.

[0070] In some embodiments, Figure 1 As shown, the first electronic device 1 further includes: a DC boost circuit 14 ; the first processing module 11 and the first power module 13 are electrically connected to the DC boost circuit 14 respectively, and the DC boost circuit 14 is electrically connected to the switch control circuit 15 .

[0071] The first processing module 11 is used to control the working state of the DC boost circuit 14 .

[0072] like Figure 3 As shown, the DC boost circuit 14 may be a BOOST boost circuit known in the art, and the BOOST boost circuit is constructed using an SGM6611C chip.

[0073] The SW port of the SGM6611C chip is electrically connected to the first power module 13; the EN port of the SGM6611C chip is electrically connected to the first processing module 11 to receive control instructions from the first processing module 11; the VOUT port of the SGM6611C chip is connected to the input end of the switch control circuit 15 through a resistor voltage divider circuit.

[0074] The resistor voltage divider circuit includes a series resistor R31 and a series resistor R32, one end of the series resistor R31 is connected to the VOUT port of the SGM6611C chip and the input end of the switch control circuit 15 respectively, the other end of the series resistor R31 is connected to one end of the series resistor R32 and to the FB port of the SGM6611C chip, and the other end of the series resistor R32 is grounded.

[0075] The output voltage VOUT of the BOOST boost circuit is VOUT=1.12*(1+R31 / R32).

[0076] At the same time, Figure 4 As shown, the switch control circuit 15 shown in this embodiment is constructed using the SGM2576 chip, the IN port of the SGM2576 chip is connected to the output end of the DC boost circuit 14, the EN port of the SGM2576 chip is electrically connected to the first processing module 11 to receive the control instruction from the first processing module 11; the VOUT port of the SGM2576 chip is electrically connected to the first adapter 16; the OCB port of the SGM2576 chip is grounded through the current limiting resistor R43.

[0077] In actual applications, if the first acquisition circuit 12 identifies that the second electronic device 2 has a short circuit or other abnormal current exceeds the standard, the SGM2576 chip automatically switches to an open circuit state so that the first electronic device 1 no longer supplies power to the outside.

[0078] In some embodiments, Figure 1 As shown, the first electronic device 1 further includes: a first charging interface 17 , and the first charging interface 17 is electrically connected to the first processing module 11 and the first power module 13 respectively.

[0079] Among them, the first charging interface 17 can be a Type-c interface well known in the art, which enables the first charging interface 17 to not only realize information interaction between the first electronic device 1 and the outside world, but also meet the charging requirements of the first power module 13 in the first electronic device 1.

[0080] In the second aspect, Figure 1 As shown, an embodiment of the utility model further provides an electronic device assembly, including: a rotating bracket 3, a second electronic device 2 and the first electronic device 1 as described above.

[0081] The first electronic device 1 and the second electronic device 2 are respectively disposed on a rotating bracket 3 , and the rotating bracket 3 is used to control the angle between the first electronic device 1 and the second electronic device 2 to switch between 0° and 360°.

[0082] It is understandable that the rotating bracket 3 includes a first frame 31, a hinge assembly 32 and a second frame 33. The first frame 31 is used to support the first electronic device 1, and the second frame 33 is used to support the second electronic device 2. The first frame 31 and the second frame 33 are rotatably arranged through the hinge assembly 32, so as to realize the switching of the angle between the first electronic device 1 and the second electronic device 2 between 0° and 360°.

[0083] In practical applications, according to the rotatable arrangement of the first frame 31 and the second frame 33, the angle formed between the first electronic device 1 and the second electronic device 2 can be limited so that the first electronic device 1 and the second electronic device 2 can maintain any required angle between 0° and 360°.

[0084] like Figure 5 As shown, when the rotating bracket 3 is in the folded state, the display surface of the first electronic device 1 and the display surface of the second electronic device 2 are in contact with each other, so that the electronic device assembly is in the folded state.

[0085] like Figure 6 As shown, when the rotating bracket 3 is in the unfolded state, the display surface of the first electronic device 1 and the display surface of the second electronic device 2 are arranged at an angle, so that the electronic device assembly is in the unfolded state. Figure 6 In the figure, the angle between the display surface of the first electronic device 1 and the display surface of the second electronic device 2 is indicated by α, and the value of α can be 90° to 180°.

[0086] In some embodiments, Figure 1 As shown, the second electronic device 2 includes: a second processing module 21 , a second acquisition circuit 22 , a second power supply module 24 and a second adapter 26 .

[0087] The second processing module 21 is in communication connection with the second adapter 26 and is electrically connected with the second power module 24 ; the second acquisition circuit 22 and the second power module 24 are electrically connected with the second adapter 26 , respectively.

[0088] The second acquisition circuit 22 is used to acquire a voltage signal when the second electronic device 2 is working, and feed the voltage signal back to the first acquisition circuit 12 through the first adapter 16 and the second adapter 26 .

[0089] It is understandable that the second electronic device 2 includes a second housing, a second control board 201 disposed on the second housing, and an electronic ink screen 28. The second processing module 21, the second acquisition circuit 22, and the second adapter 26 can be disposed on the second control board 201, respectively.

[0090] The second power module 24 may be a lithium battery module known in the art, the second processing module 21 may be a central processing unit (CPU), and the second processing module 21 is communicatively connected to the electronic ink screen 28 .

[0091] The second control board 201 is provided with a Host interface, the second processing module 21 and the second acquisition circuit 22 are electrically connected to the Host interface respectively, and the Host interface is electrically connected to the second transfer interface 26 .

[0092] Among them, one end of the second acquisition circuit 22 can be electrically connected to the second power supply module 24, and can also be electrically connected to the power supply end on the second control board 201. The other end of the second acquisition circuit 22 is electrically connected to the second adapter 26 through the Host interface to realize the collection of the voltage signal of the second electronic device 2 when it is working through the second acquisition circuit 22.

[0093] In this way, after the second electronic device 2 is turned on, according to the connection link between the first acquisition circuit 12 and the second acquisition circuit 22, it can be ensured that the first acquisition circuit 12 collects the voltage signal of the second electronic device 2 when it is working, and the first processing module 11 of the first electronic device 1 controls the switch control circuit 15 to be in the on state, so that the first electronic device 1 can charge the second electronic device 2.

[0094] When the rotating bracket 3 includes a first frame 31, a hinge assembly 32 and a second frame 33, a wired communication link can be set on the hinge assembly 32; the first end of the wired communication link extends to the first frame 31 and is provided with a first interface, the first interface and the first adapter 16 are adapted to achieve electrical connection; the second end of the wired communication link extends to the second frame 33 and is provided with a second interface, the second interface and the second adapter 26 are adapted to achieve electrical connection.

[0095] like Figure 7 The second acquisition circuit 22 can be configured to include a resistor R71 and a resistor R72, wherein a first end of the resistor R72 is electrically connected to a power supply end on the second control board 201, a second end of the resistor R72 is electrically connected to the second adapter 26, and a second end of the resistor R72 is grounded through the resistor R71.

[0096] In some embodiments, Figure 1 As shown, the second electronic device 2 further includes: a switch selection circuit 25 and a second charging interface 27 .

[0097] The second adapter port 26 and the second charging port 27 are electrically connected to the second power module 24 , respectively. The second power module 24 and the second charging port 27 are electrically connected to the second processing module 21 , respectively.

[0098] The switch selection circuit 25 has a first state and a second state; when the switch selection circuit 25 is in the first state, the second adapter 26 is electrically connected to the second power module 24; when the switch selection circuit 25 is in the second state, the second charging interface 27 is electrically connected to the second power module 24.

[0099] In practical applications, the working state of the switch selection circuit 25 can be controlled according to actual needs. When charging the second electronic device 2 through the first electronic device 1, the switch selection circuit 25 is controlled to be in the first state. When charging the second electronic device 2 through the second charging interface 27 alone, it is only necessary to control the switch selection circuit 25 to be in the second state. The operation is simple and convenient.

[0100] In some embodiments, Figure 8 As shown, the switch selection circuit 25 includes a first MOS transistor, a second MOS transistor and a third MOS transistor; the first MOS transistor, the second MOS transistor and the third MOS transistor are marked with Q1, Q2 and Q3 respectively.

[0101] The drain of the first MOS transistor Q1 is electrically connected to the second adapter 26 , and the gate and source of the first MOS transistor Q1 are connected via a first resistor R81 .

[0102] The drain of the second MOS transistor Q2 is electrically connected to the second charging interface 27 , the gate of the second MOS transistor Q2 is electrically connected to the second adapter 26 , and the gate and source of the second MOS transistor Q2 are connected via the first capacitor C81 .

[0103] The gate of the third MOS transistor Q3 is electrically connected to the second adapter 26 , the source of the third MOS transistor Q3 is electrically connected to the gate of the first MOS transistor Q1 , the gate and source of the third MOS transistor Q3 are connected through the second resistor R82 , and the source of the third MOS transistor Q3 is grounded.

[0104] The source of the first MOS transistor Q1 and the source of the second MOS transistor Q2 are electrically connected to the second power module 24 respectively.

[0105] Specifically, the first MOS transistor Q1 and the second MOS transistor Q2 are both P-channel MOSFETs, and the third MOS transistor Q3 is an N-channel MOSFET.

[0106] In practical applications, the switch selection circuit 25 of this embodiment is constructed based on the first MOS transistor, the second MOS transistor and the third MOS transistor, and the switching characteristics of the MOS transistor can be used to realize automatic switching of the switch state of the switch selection circuit 25.

[0107] Among them, when the second electronic device 2 only has the second charging interface 27 connected to the external power supply, the second MOS tube Q2 and the third MOS tube Q3 are in the on state, and the first MOS tube Q1 is in the off state. At this time, the external power supply can charge the second power module 24 of the second electronic device 2 through the second charging interface 27.

[0108] When the first adapter 16 of the first electronic device 1 is electrically connected to the second adapter 26 of the second electronic device 2, there is a voltage signal on the second adapter 26, and the second charging interface 27 is also connected to an external power supply, the first MOS transistor Q1 and the third MOS transistor Q3 are in an on state, and the second MOS transistor Q2 is in an off state. At this time, only the first electronic device 1 charges the second electronic device 2.

[0109] In some embodiments, Figure 1 and Fig. 9 As shown, the second electronic device 2 is further configured with an interface protection circuit 23; the interface protection circuit 23 includes a plurality of signal transmission channels, and each signal transmission channel is grounded through a voltage regulator tube.

[0110] The second adapter 26 is electrically connected to one end of the plurality of signal transmission channels respectively, and the other ends of the plurality of signal transmission channels are electrically connected to the second processing modules 21 respectively.

[0111] like Fig. 9 As shown, the second adapter 26 is configured with a POGO_DP terminal and a POGO_DM terminal, and the interface protection circuit 23 is specifically configured with two signal transmission channels. The POGO_DP terminal and the POGO_DM terminal are respectively connected to one end of the two signal transmission channels in a one-to-one correspondence, and the other ends of the two signal transmission channels are communicatively connected to the second processing module 21 through a BTB connector.

[0112] Wherein, protection resistors are provided on the two signal transmission channels of the interface protection circuit 23 , one signal transmission channel is grounded through a voltage regulator tube D1 , and the other signal transmission channel is grounded through a voltage regulator tube D2 .

[0113] Based on the above settings, the second adapter 26 and the interface protection circuit 23 can be electrically connected, and the interface protection circuit 23 and the second processing module 21 can be electrically connected, so that the interface protection circuit 23 can realize the voltage stabilization protection of the voltage signal on the second adapter 26 while realizing the communication signal transmission between the second processing module 21 and the second adapter 26.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
