[0053] An embodiment of the present application provides a foldable electronic device, which may include two foldable bodies that can be folded relative to each other to adjust the volume and display area of ​​the foldable electronic device; and a battery is arranged in each foldable body, and the two batteries can be connected to each other to balance the voltage of the two batteries, thereby improving the battery life of the foldable electronic device.

[0054] In some embodiments, reference Figure 1 and Figure 4 The foldable electronic device provided in the embodiment of the present application includes:

[0055] A first body 1, wherein a first electrical component 11 is disposed in the first body 1, the first electrical component 11 includes a first battery 111, and a first charging port 12 electrically connected to the first battery 111 is disposed on the first body 1;

[0056] A second body 2, wherein a second electrical component 21 is disposed in the second body 2, the second electrical component 21 includes a second battery 211, a second charging port 22 electrically connected to the second battery 211 is disposed on the second body 2, and the first body 1 and the second body 2 are relatively hinged;

[0057] The flexible connector 3 electrically connects the first electrical component 11 and the second electrical component 21 to balance the voltages of the first battery 111 and the second battery 211 .

[0058] In this embodiment, the first body 1 and the second body 2 can be two folding bodies of a foldable electronic device, and flexible screens are arranged on the two folding bodies, for example, the first body 1 is provided with a first part of the flexible screen, and the second body 2 is provided with a second part of the flexible screen. The first body 1 and the second body 2 are relatively hinged, for example, the first body 1 and the second body 2 are movably connected by a hinge or a pin, so that relative movement between the first body 1 and the second body 2 can be realized, such as the first body 1 and the second body 2 are relatively folded or relatively unfolded, so as to adjust the volume and external display area of ​​the foldable electronic device.

[0059] In this embodiment, the first charging port 12 is arranged close to the first battery 111, and the first battery 111 is charged through the first charging port 12 to shorten the charging path of the first battery 111 and reduce the voltage drop on the charging path; the second charging port 22 is arranged close to the second battery 211, and the second battery 211 is charged through the second charging port 22 to shorten the charging path of the second battery 211 and reduce the voltage drop on the charging path when the second battery 211 is charged.

[0060] The first electrical component 11 may be a component that provides power and signal control in the first body 1, and the second electrical component 21 may be a component that provides power and signal control in the second body 2. The first electrical component 11 and the second electrical component 21 are electrically connected via a flexible connector 3, and a bridge may be built between the first battery 111 of the first electrical component 11 and the second battery 211 of the second electrical component 21 via the flexible connector 3 to facilitate voltage balance between the first battery 111 and the second battery 211.

[0061] The first electrical component 11 may include an electrically connected first battery 111 and a first circuit board, and the second electrical component 21 may include an electrically connected second battery 211 and a second circuit board. In one embodiment, the flexible connector 3 is directly connected between the first battery 111 and the second battery 211. In another embodiment, the flexible connector 3 is directly connected between the first circuit board and the second circuit board to connect the first battery 111 and the second battery 211 through the circuit boards in the first electrical component 11 and the second electrical component 21, thereby achieving the purpose of balancing the voltages of the first battery 111 and the second battery 211.

[0062] In one embodiment, the voltages of the first battery 111 and the second battery 211 are equal when they are fully charged. The first electrical component 11 and the second electrical component 21 are electrically connected via the flexible connector 3, so that power can be transmitted between the first battery 111 and the second battery 211, and the power of the high-voltage battery is used to supplement the power of the low-voltage battery, so as to ensure that the first battery 111 and the second battery 211 are fully charged at the same time; and when the first battery 111 and the second battery 211 are charged through a charging port, since the lengths of the charging paths of the two batteries are different, the charging impedances of the two batteries will be different, which will in turn affect the charging speed of the batteries. For example, the impedance of the battery with a short charging path is smaller during charging, that is, the voltage loss of the battery with a short charging path is also smaller during charging, which speeds up the charging speed and increases the voltage of the battery, resulting in inconsistent voltages of the two batteries, causing the problem that one battery cannot be fully charged when the other battery is fully charged; and when one of the first battery 111 and the second battery 211 has a low voltage and is insufficiently discharged, the other of the first battery 111 and the second battery 211 can replace it to provide the discharge function.

[0063] In one embodiment, a double-headed charging cable can be used to charge the foldable electronic device. The two charging heads of the charging cable are respectively plugged into the first charging port 12 and the second charging port 22 to charge the first battery 111 and the second battery 211 at the same time, ensuring the synchronization of the first battery 111 and the second battery 211 during charging, facilitating the calculation of the power of the first battery 111 and the second battery 211. For example, only one set of power meters is needed to monitor the power of the first battery 111 and the second battery 211.

[0064] In one embodiment, when the first battery 111 is charged to 50% of the battery capacity through the first charging port 12, and the second battery 211 is charged to 40% of the battery capacity through the second charging port 22, since the flexible connector 3 can balance the voltages of the first battery 111 and the second battery 211, the power of the first battery 111 can be compensated to the second battery 211. For example, after balancing, the power of the first battery 111 and the second battery 211 are both 45% of their respective battery capacities. By measuring the power of any one of the first battery 111 and the second battery 211 through a set of power meters, the power of the first battery 111 and the second battery 211 can be known.

[0065] In another embodiment, two charging cables can be used for charging. After matching, the two charging cables are respectively plugged into the first charging port 12 and the second charging port 22, thereby ensuring the charging synchronization of the first battery 111 and the second battery 211, and preventing the first battery 111 and the second battery 211 from being overcharged or undercharged.

[0066] In one embodiment, the flexible connector 3 may be a FPC (Flexible Printed Circuit) or a flexible cable. The flexible connector 3 spans the hinge position of the first body 1 and the second body 2 and electrically connects the first electrical component 11 and the second electrical component 21. Since the flexible connector 3 is not used for charging but only for voltage balancing and discharge channels, that is, the flexible connector 3 is not on the charging path of the first battery 111 and the second battery 211. For example, when the first battery 111 and the second battery 211 are charged with high power through the first charging port 12 and the second charging port 22 respectively, the high-power charging current does not need to pass through the flexible connector 3, so that the flexible connector 3 will not be affected by the increase in charging power; and when the first battery 111 and the second battery 211 are charged through one charging port, the first battery 111 and the second battery 211 need to be connected through a thicker FPC to ensure the charging overcurrent capacity; and in the folding electronic device provided in the embodiment of the present application, the first battery 111 and the second battery 211 are charged through the first charging port 12 and the second charging port 22 respectively, avoiding the problem of requiring a thicker FPC for high-power fast charging.

[0067] The foldable electronic device provided in the embodiment of the present application includes a first body 1, in which a first electrical component 11 is arranged, the first electrical component 11 includes a first battery 111, and the first body 1 is provided with a first charging port 12 electrically connected to the first battery 111; a second body 2, in which a second electrical component 21 is arranged, the second electrical component 21 includes a second battery 211, and the second body 2 is provided with a second charging port 22 electrically connected to the second battery 211, and the first body 1 and the second body 2 are relatively hinged; a flexible connector 3, the flexible connector 3 electrically connects the first electrical component 11 and the second electrical component 21 to balance the voltage of the first battery 111 and the second battery 211, thereby improving the battery life of the foldable electronic device.

[0068] In one embodiment, see Figure 4 , the first electrical component 11 includes a first circuit board 112, and the second electrical component 21 includes a second circuit board 212;

[0069] The first circuit board and the second circuit board are arranged on both sides of the hinge structure, and the first circuit board and the second circuit board are connected by the flexible connecting member.

[0070] In this embodiment, the first body 1 and the second body 2 can be relatively hinged by a hinge structure to facilitate the flexibility of relative folding of the first body 1 and the second body 2; and the first circuit board 112 and the second circuit board 212 are arranged on both sides of the hinge structure, and the first circuit board 112 and the second circuit board 212 are arranged relative to each other, so that the first circuit board 112 and the second circuit board 212 are close to each other.

[0071] The first circuit board 112 is electrically connected to the first battery 111, and the second circuit board 212 is electrically connected to the second battery 211. The flexible connector 3 electrically connects the first circuit board 112 and the second circuit board 212, so that voltage balance between the first battery 111 and the second battery 211 can be achieved through the first circuit board 112 and the second circuit board 212.

[0072] In one embodiment, see Figure 1 , the first battery 111 includes a first battery protection board 1112, and the second battery 211 includes a second battery protection board 2112;

[0073] The first battery protection plate and the second battery protection plate are arranged on both sides of the hinge structure, and the first battery protection plate and the second battery protection plate are connected by the flexible connector.

[0074] In this embodiment, the first battery protection board 1112 can limit the current and voltage when the charging current and voltage of the first battery 111 are too high, so as to ensure the charging safety of the first battery 111; the second battery protection board 2112 can limit the current and voltage when the charging current and voltage of the second battery 211 are too high, so as to ensure the charging safety of the second battery 211.

[0075] The first battery protection plate 1112 and the second battery protection plate 2112 are arranged on both sides of the hinge structure, and the first battery protection plate 1112 and the second battery protection plate 2112 are arranged opposite to each other, so that the first battery protection plate 1112 and the second battery protection plate 2112 are close to each other. The first battery protection plate 1112 and the second battery protection plate 2112 are electrically connected through the flexible connector 3, and the voltage balance between the first battery 111 and the second battery 211 can be achieved through the first battery protection plate 1112 and the second battery protection plate 2112.

[0076] In one embodiment, see Figure 1 and Figure 4 , the first electrical component 11 includes a first circuit board 112 , and the second electrical component 21 includes a second circuit board 212 ;

[0077] The first charging port 12 is electrically connected to the first battery 111 through the first circuit board 112 , and the second charging port 22 is electrically connected to the second battery 211 through the second circuit board 212 .

[0078] In this embodiment, a charging management module may be provided on the first circuit board 112. When the first battery 111 is charged through the charging cable on the first charging port 12, parameters such as the charging current and voltage will be controlled by the charging management module on the first circuit board 112 to ensure the charging stability and safety of the first battery 111. A charging management module may also be provided on the second circuit board 212. When the second battery 211 is charged through the charging cable on the second charging port 22, parameters such as the charging current and voltage will be controlled by the charging management module on the second circuit board 212 to ensure the charging stability and safety of the second battery 211.

[0079] In one embodiment, see Figure 1 The first charging port 12 is disposed on a side of the first body 1 away from the second body 2 , and the second charging port 22 is disposed on a side of the second body 2 away from the first body 1 .

[0080] In this embodiment, when the first battery 111 is charged through the charging cable plugged into the first charging port 12, the first circuit board 112 can control the charging current and voltage to adjust the charging power of the first battery 111; when the second battery 211 is charged through the charging cable plugged into the second charging port 22, the second circuit board 212 can control the charging current and voltage to adjust the charging power of the second battery 211; and the first charging port 12 and the second charging port 22 are located on two sides of the folding electronic device that are far away from each other. On the basis of facilitating the first charging port 12 to be close to the first battery 111 and the first circuit board 112, and the second charging port 22 to be close to the second battery 211 and the second circuit board 212, the first charging port 12 and the second charging port 22 can be kept away from each other to avoid mutual entanglement between the charging cables on the first charging port 12 and the second charging port 22.

[0081] In one embodiment, see Figure 1 , the first battery 111 includes a first battery body 1111 and a first battery protection board 1112 , and the first circuit board 112 is electrically connected to the first battery body 1111 through the first battery protection board 1112 ;

[0082] The second battery 211 includes a second battery body 2111 and a second battery protection board 2112 , and the second circuit board 212 is electrically connected to the second battery body 2111 through the second battery protection board 2112 ;

[0083] The first battery protection board 1112 and the second battery protection board 2112 are arranged on both sides of the hinge structure, and the first battery protection board 1112 and the second battery protection board 2112 are electrically connected through the flexible connector 3.

[0084] In this embodiment, the first battery protection board 1112 is arranged on the first battery body 1111, and can limit the current and voltage when the charging current and voltage of the first battery body 1111 are too high, so as to ensure the charging safety of the first battery 111; the second battery protection board 2112 is arranged on the second battery body 2111, and can limit the current and voltage when the charging current and voltage of the second battery body 2111 are too high, so as to ensure the charging safety of the second battery 211.

[0085] The first body 1 and the second body 2 can be relatively hinged by a hinge structure to facilitate the flexibility of relative folding of the first body 1 and the second body 2; and the first battery protection plate 1112 and the second battery protection plate 2112 are arranged on both sides of the hinge structure and are electrically connected through the flexible connector 3 to facilitate voltage balance between the first battery 111 and the second battery 211; for example, when the voltage of the first battery 111 is lower than that of the second battery 211, the second battery 211 can be discharged to the first battery 111 to increase the voltage of the first battery 111 to ensure voltage balance between the first battery 111 and the second battery 211.

[0086] In one embodiment, the first circuit board has a first charging management module, and the first charging management module is used to control the charging process of the first battery according to the charging voltage;

[0087] The second circuit board has a second charging management module, and the second charging management module is used to control the charging process of the second battery according to the charging voltage.

[0088] In one embodiment, see Figure 1 , the first circuit board 112 is a first main board, and the first main board is located between the first battery 111 and the first charging port 12;

[0089] The first main board has a first charging management module, the first battery 111 is connected to a first battery FPC 113 , and the first battery FPC 113 is electrically connected to the first charging management module.

[0090] In this embodiment, one end of the first battery FPC 113 is connected to the first charging management module on the first main board, and the other end of the first battery FPC 113 is connected to the first battery 111; see Figure 2 and Figure 3 When charging the first battery 111, one end of the charging cable is connected to the power adapter (not shown in the figure), and the other end of the charging cable is inserted into the first charging port 12, so that a charging path from the power adapter, the first charging head 101 of the charging cable, the first charging port 12, the first charging management module of the first mainboard, the first battery FPC 113, the first battery protection board 1112 to the first battery body 1111 can be formed ( Figure 1The current path 1) is shown by the dotted line. This charging path corresponds to the sequential arrangement order of the first charging port 12, the first mainboard and the first battery 111, which shortens the length of the charging path of the first battery 111 and improves the charging efficiency of the first battery 111.

[0091] In this embodiment, the charging process of the first battery 111 is controlled by the first charging management module on the first mainboard. For example, charging of the first battery 111 is stopped when the charging voltage is too high. This ensures the charging safety of the first battery 111 while improving the control integration of the first mainboard.
