As shown in fig. 8, in the case where the electronic apparatus 100 is in the closed state, the first connector 11 and the second connector 12 can be in contact conduction. It can also be seen that the manner and the position of the first and second connection members 11, 12 are exposed to the touch and conduction of the first and second connection members 11, 12 when the electronic device 100 is in the closed state.

Fig. 9 is a schematic diagram of the structure of the first connector 11 and the second connector 12 in the second charging circuit 62 in fig. 7, and as shown in fig. 9, the second charging circuit 62 includes a first connection line 621 and a second connection line 622 connected to the second battery 4, and one of the first connection line 621 and the second connection line 622 may be a line through which current flows into the second battery 4 when the second charging circuit 62 charges the second battery 4, and the other may be a line through which current flows out of the second battery 4 when the second charging circuit 62 charges the second battery 4.

The first connector 11 may include first and second sub-connectors 111 and 112 respectively positioned at the first and second connection lines 621 and 622, and the second connector 12 includes third and fourth sub-connectors 121 and 122 respectively positioned at the first and second connection lines 621 and 622. In the case where the electronic device 100 is in the closed state, the first sub-connector 111 and the third sub-connector 121 are in contact conduction, and the second sub-connector 112 and the fourth sub-connector 122 are in contact conduction.

Herein, referring to fig. 7 and 9, a portion of the second charging circuit 62 between the first connection member 11 and the second connection member 12 is defined as an intermediate circuit 62A, and the intermediate circuit 62A includes a first intermediate circuit 621A located between the first sub-connection member 111 and the third sub-connection member 121 in the first connection line 621, and a second intermediate circuit 622A located between the second connection line 622 and the fourth sub-connection member 122 in the second connection line 622.

Fig. 10 is a charging circuit diagram of an electronic device 100 in an open state, where part (a) in fig. 10 is a case where a first battery 5 and a second battery 4 are connected in parallel to a charging circuit 6, and part (b) in fig. 10 is a case where the first battery 5 and the second battery 4 are connected in series to the charging circuit 6; as shown in fig. 10, when the first connector 11 and the second connector 12 are not in contact conduction, the impedance of the intermediate circuit 62A is R1 and R2, where R1 is the impedance of the first intermediate circuit 621A located between the first sub-connector 111 and the third sub-connector 121 in the first connection line 621, R2 is the impedance of the second intermediate circuit 622A located between the second sub-connector 112 and the fourth sub-connector 122 in the second connection line 622, and R1 is an impedance equivalent to Ra in the related art, and R2 is an impedance equivalent to Rb in the related art, and the impedance values of both are considered to be of the same order.

Fig. 11 is a charging circuit diagram of an electronic device 100 in a closed state, where part (a) in fig. 11 is a case where a first battery 5 and a second battery 4 are connected in parallel to a charging circuit 6, and part (b) in fig. 11 is a case where the first battery 5 and the second battery 4 are connected in series to the charging circuit 6; as shown in fig. 11, after the first connection element 11 and the second connection element 12 are in contact conduction, the intermediate circuit 62A of the second charging circuit 62 between the first connection element 11 and the second connection element 12 is shorted, which corresponds to adding a path parallel to the intermediate circuit 62A, and the added parallel path includes a first parallel path parallel to the first intermediate circuit 621A, and a second parallel path parallel to the second intermediate circuit 622A, where the impedance of the first parallel path is R3, the impedance of the second parallel path is R4, R3 is parallel to R1, and R4 and R2 are parallel.

Since R3 is the impedance formed by the contact between the first sub-connector 111 and the third sub-connector 121, R4 is the impedance formed by the contact between the second sub-connector 112 and the fourth sub-connector 122, the impedance values of R3 and R4 are both extremely low, and compared with R1 and R2, R3 is much smaller than R1 and R4 is much smaller than R2, so that the impedance after the parallel connection of R3 and R1 is smaller than R1, and the impedance after the parallel connection of R4 and R2 is much smaller than R2. It should be noted that "much smaller" in this context means that the two differ by at least one order of magnitude, for example, that a is much smaller than B means that the ratio of a to B is not more than 0.1.

As can be seen from the above comparison, by providing the first connection member 11 and the second connection member 12, the impedance of the second charging circuit 62 when the electronic device 100 is in the closed state can be made much smaller than the impedance of the second charging circuit 62 when the electronic device 100 is in the open state. As can be seen from the above description, R1 and Ra in the related art, R2 and Rb in the related art can be considered as impedance values belonging to the same order, and thus the impedance of the second charging circuit 62 when the electronic device 100 is in the closed state is also much smaller than the impedance of the charging path of the second battery 4 in the related art.

Therefore, when the electronic device 100 having the above-described configuration is charged, if the electronic device 100 is in the on state, the impedance of the second charging circuit 62 is r1+r2. If the electronic device 100 is in the closed state, the impedance of the second charging circuit 62 is the impedance after the parallel connection of R3 and R1 and the impedance after the parallel connection of R4 and R2, and the impedance is greatly reduced; therefore, the charging loss can be reduced, the heating value is reduced, the charging efficiency can be improved, and the high-power rapid charging is facilitated due to the reduction of the impedance.

For the electronic device 100 provided in the embodiment of the present application, the second connection member 12 in the second portion 2 may be connected to the second charging circuit 62 at a position as close as possible to the second battery 4, and the first connection member 11 in the first portion 1 may be connected to the second charging circuit 62 at a position as close as possible to the power input device 13. By such design, the intermediate circuit 62A of the second charging circuit 62 between the first connector 11 and the second connector 12 can have a larger duty ratio as much as possible, so that when the first connector 11 and the second connector 12 are in contact conduction, the impedance of the second charging circuit 62 when the electronic device 100 is in the off state can be reduced as much as possible, thereby reducing the charging loss, reducing the heat generation amount, and improving the charging efficiency.

In some embodiments, the first connector 11 and the second connector 12 may each comprise at least one of a metal contact, a metal dome, a pogo pin, or an electrical connector.

For example, the first connection member 11 and the second connection member 12 may be one of a combination of metal contact-metal contact, metal contact-metal spring, metal spring-metal spring, metal contact-spring pin, and electric connector-electric connector, or other connection structures capable of realizing the contact conduction function may be selected.

Therefore, the first and second connection members 11 and 12 should be provided on two surfaces, respectively, which are adjacent to and close to each other when the electronic device 100 is in the closed state. Also, the arrangement positions of the first connector 11 and the second connector 12 should not affect the normal functions of the electronic device 100.

The electronic device 100 generally has a large number of setting positions satisfying the above requirements, and thus the setting positions of the first connector 11 and the second connector 12 may be different for different electronic devices 100.

In the following, several embodiments of the arrangement positions of the first connector 11 and the second connector 12 will be exemplarily described, and it will be understood that the electronic device 100 provided in the embodiments of the present application is not limited to the following several embodiments, and those skilled in the art may select suitable arrangement positions of the first connector 11 and the second connector 12 in different electronic devices 100 according to the description herein.

For example, for an invaginated electronic device 100, as shown in fig. 4 and 5, both the first portion 1 and the second portion 2 include a display bezel 100C located at the periphery of the foldable display 9. When the electronic device 100 is in the closed state, the display front 100A is located at an inner side with respect to the display back 100B, and the first connector 11 and the second connector 12 may be both disposed on the display front 100A of the electronic device 100 and disposed in the display bezel 100C.

As shown in fig. 4 and 5, the first connecting member 11 is disposed on the first frame 101 of the first portion 1, which is away from the rotating shaft assembly 3 and opposite to the rotating shaft assembly 3; the second connecting piece 12 is disposed on the second frame 102 of the second portion 2 away from the rotating shaft assembly 3 and opposite to the rotating shaft assembly 3.

For another example, for the folded-out electronic device 100, the display front 100A is located outside when the electronic device 100 is in the closed state; as shown in fig. 17, the first connector 11 and the second connector 12 may be both disposed on the display back surface 100B of the electronic device 100, that is: the first and second connectors 11, 12 may be provided to the back shell of the first part 1 and the back shell of the second part 2 of the electronic device 100, respectively. Since the display back surface 100B does not affect the display of the foldable display screen 9, a large number of positions can be allowed.

With the electronic device 100 in the closed state, the end of the second portion 2 is opposite the protrusion 18. Corresponding to such products, the first and second connection members 11, 12 may be arranged with reference to the above folded-in and folded-out products, or may be arranged on opposite surfaces of the protrusion 18 and the second portion 2, respectively, when the electronic device 100 is in the closed state, the opposite surfaces comprising a first surface 103 at the protrusion 18 and a second surface 104 at the second portion 2.

In some embodiments, the protrusion 18 and the second part 2 are provided with a catch 19, which catch 19 is used to lock the first part 1 and the second part 2 when the electronic device 100 is in the closed state. In such an electronic device 100, the first connector 11 and the second connector 12 may be integrated in the buckle 19, or may be disposed near the buckle 19. So designed, the interaction force of the first connecting piece 11 and the second connecting piece 12 in contact can be increased through the buckle 19, so that the reliability of the contact between the first connecting piece 11 and the second connecting piece 12 is ensured, and the second battery 4 is charged through the first connecting piece 11 and the second connecting piece 12.

By increasing the adsorption force, the interaction force of the first and second connection members 11 and 12 at the time of contact can be increased, and the reliability at the time of contact can be ensured, thereby facilitating the charging of the second battery 4 through the first and second connection members 11 and 12.

In some other embodiments, the second charging circuit 62 may be provided partially on the first circuit board 14, partially disposed in the third circuit board 15, and connected to the second battery 4 through the third circuit board 15.
