Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] With the development of technology, electronic products such as smart phones, tablet computers, Bluetooth headsets, smart watches, etc. have become indispensable electronic devices in people's daily life and entertainment. And with the popularization of electronic devices, the charging time of electronic devices has received more and more attention, and users hope that the charging time of their electronic devices will be short.

[0003] However, when electronic devices are charged in a low-temperature environment, the ambient temperature is too low, resulting in the battery's temperature being too low, which increases the battery's own internal resistance. As a result, the battery can only support a small current pre-charge before charging. As a result, the battery cannot be charged efficiently in a short period of time, affecting the battery's charging speed, causing the battery to be unable to be fully charged quickly, which in turn affects the user experience. Summary of the invention

[0004] An embodiment of the present application discloses an electronic device that can increase the temperature of a battery when charging in a low-temperature environment, thereby accelerating the speed at which the battery enters a state capable of high-current charging, thereby increasing the charging speed of the battery, shortening the user's waiting time, and improving the user's charging experience.

[0005] In order to achieve the above objectives, some embodiments of the present application disclose an electronic device, the electronic device comprising:

[0006] A casing, wherein the casing is provided with a through hole communicating with the inside and the outside of the casing;

[0007] A battery, wherein the battery is disposed inside the housing;

[0008] A mainboard, the mainboard is arranged inside the housing and is electrically connected to the battery;

[0009] A sub-board, the sub-board is arranged inside the housing, the sub-board is provided with a charging port, and the charging port is arranged at the through hole;

[0010] at least two first connection lines; and,

[0012] Some embodiments of the present application disclose an electronic device, the electronic device comprising:

[0013] A casing, wherein the casing is provided with a through hole communicating with the inside and the outside of the casing;

[0014] A battery, wherein the battery is disposed inside the housing;

[0015] A mainboard, the mainboard is arranged inside the housing and is electrically connected to the battery;

[0016] A sub-board, the sub-board is arranged inside the housing, the sub-board is provided with a charging port, and the charging port is arranged at the through hole;

[0017] a first connecting line; and,

[0018] Two conductive wires are connected through the first connecting wire to form a conductive circuit, the conductive circuit is connected between the battery and the charging port, and the conductive circuit is used to pass current to heat the battery when the battery is in a low temperature state.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] The electronic device provided by the embodiment of the present application is provided with a plurality of conductive wires, and two adjacent conductive wires are connected through a first connecting wire to form a conductive circuit, the impedance of the conductive circuit is increased, and the conductive circuit is electrically connected between the charging port of the sub-board and the battery. When the charging port is connected to an external power source in a low temperature environment to charge the battery, the external current flows into the conductive circuit through the charging port and the sub-board. Since the impedance of the conductive circuit is much greater than the impedance of a single conductive wire, the conductive circuit can generate significant heat when current is passed through the battery when the battery is in a low temperature state, so that the heat generated by the conductive circuit can be used to quickly heat the battery, so that the temperature of the battery can rise, thereby accelerating the speed at which the battery enters a state capable of high current charging, thereby increasing the charging speed of the battery, shortening the user's waiting time, and improving the user's charging experience.

[0021] When the battery is in a low temperature state and still has usable power, by putting the battery in a discharge state, the battery current can flow into the conductive circuit through the motherboard, and the heat generated by the current passing through the conductive circuit can be used to quickly heat the battery, so that the battery temperature can rise, thereby allowing the battery to output a large current to support the normal operation of electronic equipment, such as allowing the electronic equipment to start up and run normally.

Obviously, the exemplary embodiments described are only part of the embodiments of the present application, not all of the embodiments. That is, the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

[0061] It should be noted that the brief description of terms in this application is only for the convenience of understanding the implementation methods described below, and is not intended to limit the implementation methods of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the technical field of this application. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0062] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0063] The terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first sub-switch may be referred to as a second sub-switch, and similarly, a second sub-switch may be referred to as a first sub-switch. Both the first sub-switch and the second sub-switch are sub-switches, but they are not the same sub-switch.

[0064] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0065] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0066] In the description of the present application, it should be noted that the singular forms of "a", "an" and "said / the" may also include plural forms, unless the context clearly indicates otherwise.

[0067] In addition, the term "and / or" used in this specification includes any and all combinations of the relevant listed items. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. That is, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0068] With the development of science and technology, various electronic products, such as smart phones, tablet computers, Bluetooth headsets, smart watches, etc., appear in people's daily lives. People can use electronic devices for work, entertainment, study, etc., making these electronic products gradually become indispensable electronic devices in people's daily life and entertainment.

[0069] When the power of an electronic device is low, it needs to be charged. With the gradual popularization of fast charging technology, more and more electronic devices have fast charging functions to shorten the charging time of electronic devices.

[0070] However, when electronic devices are in a low-temperature environment, the temperature of the battery will be too low due to the low ambient temperature, which will increase the internal resistance of the battery itself. On the one hand, when the electronic device is charging, the battery can only support a small current pre-charge before charging, which will cause the battery to be unable to charge efficiently in a short period of time, affecting the battery charging speed, causing the battery to be unable to be fully charged quickly, thereby affecting the user experience; on the other hand, it will cause the battery to be unable to output a large current and be unable to meet the current required for the normal operation of the electronic device, thereby causing the electronic device to work abnormally or even shut down, greatly reducing the user experience.

[0071] In view of this, an embodiment of the present application provides an electronic device that can increase the battery temperature in a low temperature environment to ensure the charging and discharging performance of the battery.

[0072] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0073] See also Figure 1 , Figure 1 It is shown that the electronic device in the present application is a smart phone, but it can be understood that the drawings of the present application are only illustrative of the electronic device 100 being a smart phone, and do not limit the electronic device 100 of the present application to only being a smart phone.

[0074] In other implementations of the present application, the electronic device 100 may also be a laptop computer, a tablet computer, a television, a smart wearable device (such as a smart watch, a smart wristband, smart glasses, ear phones, etc.), a personal digital assistant (PDA), an e-book reader, or other electronic products with a charging function, which is not specifically limited in the present application.

[0075] It should be known that when the electronic device 100 adopts a smart phone, the electronic device 100 can be an ordinary mobile phone or a foldable mobile phone, and the present application does not specifically limit the specific form of the electronic device 100.

[0076] To facilitate explanation of the positions of various components in the electronic device 100, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the electronic device 100, wherein the x-axis direction is the length direction of the electronic device 100, the y-axis direction is the width direction of the electronic device 100, and the z-axis direction is the thickness direction of the electronic device 100.

[0077] See also Figure 2 , Figure 2 This is a schematic diagram of the decomposed structure of an electronic device in a specific embodiment. The electronic device 100 provided in the embodiment of the present application includes a housing 10, which is mainly used to fix and protect electronic devices or structures arranged inside the housing 10.

[0078] Optionally, the housing 10 may include a display screen 11, a middle frame 12, and a back cover 13 sequentially arranged along the thickness direction of the electronic device 100, one side of the middle frame 12 is connected to the edge of the display screen 11, and the other side of the middle frame 12 is connected to the edge of the back cover 13, so as to form a complete appearance structure of the electronic device 100. The display screen 11, the middle frame 12, and the back cover 13 form an internal space of the electronic device 100, and in this embodiment, the middle frame 12 and the back cover 13 may be a separate structure or an integrated structure.

[0079] The electronic device 100 provided in the embodiment of the present application further includes a battery 20, a main board 30 and a sub-board 40, which are all arranged in the internal space of the housing 10 and can be installed on the middle frame 12, so that the middle frame 12 can provide support and protection for various electronic devices inside the electronic device 100. The main board 30 is electrically connected to the battery 20 and the sub-board 40 respectively.

[0080] It should be noted that, in the implementation of this application, Figure 2 The example of the electronic device 100 having the battery 20, the main board 30 and the sub-board 40 disposed therein is used for exemplary description, and the electronic device 100 of the present application is not limited to having only the battery 20, the main board 30 and the sub-board 40 disposed therein. In other implementations of the present application, the electronic device 100 may also be provided with a camera module, a microphone, a fingerprint module, a card tray, a motor and various sensors and other devices, and the present application does not make specific limitations on this.

[0081] Those skilled in the art will appreciate that the structures illustrated in the embodiments of the present application do not constitute specific limitations on the electronic device 100. In other possible implementations of the present application, the electronic device 100 may include fewer components than those listed above, or more components, or combine certain components, or separate certain components, or arrange the components differently.

[0082] See also Figure 2 The housing 10 provided in the embodiment of the present application is provided with a through hole 14 communicating with its internal space and external space, the main board 30 is electrically connected to the battery 20, and the sub-board 40 is provided with a charging port 41 electrically connected to the main board 30. For example, the charging port 41 can be a Universal Serial Bus (USB) interface. The charging port 41 is arranged at the through hole 14 so that a charger can be inserted into the charging port 41 to charge the battery 20.

[0083] That is, when the battery 20 is charged by wire, the charger is inserted into the charging port 41 of the sub-board 40, and the external current enters from the charging port 41 on the sub-board 40 and reaches the battery 20 through the main board 30 to charge the battery 20. The charging process can be fast charging or normal charging, which is not specifically limited in this application.

[0084] Optionally, see Figure 3 , Figure 3 Schematic diagram of the internal structure of an electronic device in a specific embodiment. A connecting line 31, such as a charge pump circuit (Charge Pump), is provided on the main board 30. The connecting line 31 is electrically connected to the battery 20 and the charging port 41 respectively. When the battery 20 is charged by wire, the charger is inserted into the charging port 41 of the sub-board 40, and the external current enters from the charging port 41 on the sub-board 40 and reaches the battery 20 through the connecting line 31 to charge the battery 20.

[0085] like Figure 3 As shown, the electronic device 100 provided in the embodiment of the present application also includes a first connecting line 50 and a plurality of conductive lines 60. Two adjacent conductive lines 60 are connected through the first connecting line 50 to form a conductive circuit. The conductive circuit is connected between the battery 20 and the charging port 41, that is, the conductive circuit is connected between the connecting circuit 31 and the charging port 41 to achieve electrical connection between the charging port 41 and the connecting circuit 31. Therefore, when the charger is inserted into the charging port 41, the external current can enter from the charging port 41, reach the conductive circuit and the connecting circuit 31, and reach the battery 20 through the connecting circuit 31 to achieve charging of the battery 20.

[0086] Among them, the battery 20 has a first side and a second side opposite to each other in the thickness direction of the electronic device 100, the first side is arranged toward the back cover 13, and the second side is arranged away from the back cover 13, and the plurality of conductive wires 60 may all be located on the first side of the battery 20, or may all be located on the second side of the battery 20, or a part of the conductive wires 60 may be located on the first side of the battery 20, and another part of the conductive wires 60 may be located on the second side of the battery 20, and the present application does not make any specific limitation on this.

[0087] In the present application, the conductive circuit is used not only to realize the electrical connection between the charging port 41 and the connecting circuit 31, thereby realizing the electrical connection between the charging port 41 and the battery 20, so that the external current can be connected through the charging port 41 to charge the battery 20, but also to pass the current to heat the battery 20 when the battery 20 is in a low temperature state, so as to increase the temperature of the battery 20. The battery 20 in a low temperature state can be understood as the state of the battery 20 in a low temperature environment, and the temperature of the battery 20 at this time is lower than 15°C, for example, the temperature of the battery 20 is in the range of -15°C-15°C.

[0088] Specifically, when the battery 20 is in a low temperature state, if the battery 20 needs to be charged, the charger can be inserted into the charging port 41, and the external current reaches the conductive circuit through the charging port 41, and reaches the connecting circuit 31 through the conductive circuit, and finally reaches the battery 20 through the connecting circuit 31, so that the battery 20 is in a charging state. In this process, although only small current charging is supported in the early stage of charging, because the impedance of the conductive circuit is much greater than the impedance of a single conductive line 60, the impedance increases, so that the conductive circuit can generate significant heat when current is passed, and the heat generation increases, so that the heat generated by the conductive circuit can be used to quickly heat the battery 20, so that the temperature of the battery 20 can rise, and then speed up the speed at which the battery 20 enters a state capable of large current charging, so that the battery 20 can enter a normal charging state, such as a fast charging state or a normal charging state, thereby increasing the charging speed of the battery 20, shortening the user's waiting time, and improving the user's charging experience.

[0089] If the battery 20 still has available power, but the output current is too small due to the low temperature of the battery 20, and the battery 20 cannot output a large current, causing the electronic device 100 to work abnormally or even shut down, the OTG (On-The-Go) function of the electronic device 100 can be used to put the battery 20 in a discharge state. At this time, the battery 20 can output current, and the current output by the battery 20 can flow into the conductive circuit through the connecting line 31. In this process, the conductive circuit can also generate significant heat, so that the heat generated by the conductive circuit can be used to quickly heat the battery 20, so that the temperature of the battery 20 can rise, so that the battery 20 can output a large current to support the normal operation of the electronic device 100, such as allowing the electronic device 100 to start up and run normally, avoiding the electronic device 100 from shutting down, and allowing the power of the battery 20 to be fully utilized by the electronic device 100.

[0090] An exemplary example is Figures 3 to 5 As shown, there is one first connecting line 50 and two conductive lines 60. The two conductive lines 60 are connected through the first connecting line 50 to form a conductive circuit, which is connected between the connecting line 31 and the charging port 41. The conductive circuit is used to pass current to heat the battery 20 when the battery 20 is in a low temperature state.

[0091] Alternatively, if Figure 3 As shown, the shape of the first connecting line 50 is a straight line, or Figure 4 and Figure 5 As shown, the shape of the first connecting line 50 can also be a curve, such as an arc or a broken line. The first connecting line 50 is a curve. When the spacing between the two conductive lines 60 is the same, compared with the straight first connecting line 50, the curved first connecting line 50 has a longer line length, a greater impedance, and a greater heat generation, which can increase the temperature of the battery 20 more quickly.

[0092] Another exemplary example is Figures 6 to 8 As shown, there are at least two first connecting lines 50, such as two, three, four or five, etc., and there are at least three conductive lines 60, such as three, four, five, six, seven, etc., two adjacent conductive lines 60 are connected by a first connecting line 50, and two adjacent first connecting lines 50 are respectively located on both sides of the conductive line 60 along the line length direction, so that at least three conductive lines 60 are connected to form a conductive circuit, which is connected between the connecting line 31 and the charging port 41, and the conductive circuit is used to pass current to heat the battery when the battery 20 is in a low temperature state, so as to increase the temperature of the battery 20.

[0093] Alternatively, if Figure 6 As shown, the shape of the first connecting line 50 is a straight line, or Figure 7 and Figure 8As shown, the shape of the first connecting line 50 can also be a curve, such as an arc or a broken line. The first connecting line 50 is a curve. When the spacing between the two conductive lines 60 is the same, compared with the straight first connecting line 50, the curved first connecting line 50 has a longer line length, a greater impedance, and a greater heat generation, which can increase the temperature of the battery 20 more quickly.

[0094] In some embodiments, the battery 20, the main board 30 and the sub-board 40 can be arranged along the length of the conductive line 60, and the battery 20 is located between the main board 30 and the sub-board 40, and the battery 20 is in contact with the conductive line. The heat generated by the conductive line can be quickly transferred to the battery 20, so that the temperature of the battery 20 rises quickly.

[0095] In some embodiments, Figures 9 to 11 As shown, when the number of the conductive wires 60 is at least four, for example, when the conductive wires 60 are four, five, six, seven, etc., the electronic device 100 also includes a second connecting wire 70, at least three conductive wires 60 are connected through the first connecting wire 50 to form a series circuit, and the remaining conductive wires 60 are connected in parallel in the series circuit through the second connecting wire 70 to form a conductive circuit.

[0096] The first exemplary one is Fig. 9 As shown, there are four conductive wires 60, and the four conductive wires 60 are arranged along Fig. 9 From left to right in the figure, there are the first conductive line 60a, the second conductive line 60b, the third conductive line 60c and the fourth conductive line 60d, there are two first connecting lines 50, there are two second connecting lines 70, the first conductive line 60a and the second conductive line 60b are connected through one first connecting line 50, the second conductive line 60b and the third conductive line 60c are connected through one first connecting line 50 to form a series circuit, and both ends of the fourth conductive line 60d are respectively connected in parallel to the third conductive line 60c through the second connecting lines 70 to form the aforementioned conductive circuit.

[0097] The second exemplary one is Fig.10 As shown, there are four conductive wires 60, and the four conductive wires 60 are arranged along Fig.10From left to right in the figure, there are the first conductive line 60a, the second conductive line 60b, the third conductive line 60c and the fourth conductive line 60d, there are two first connecting lines 50, and there is one second connecting line 70. The first conductive line 60a and the third conductive line 60c are connected through one first connecting line 50, and the third conductive line 60c and the fourth conductive line 60d are connected through one first connecting line 50 to form a series circuit. One end of the second conductive line 60b is connected to the third conductive line 60c through the second connecting line 70, and the other end of the second conductive line 60b is connected to the first connecting line 50 connected between the first conductive line 60a and the third conductive line 60c, so as to be connected in parallel to the third conductive line 60c to form the aforementioned conductive circuit.

[0098] It can be understood that in other embodiments, the other end of the second conductive line 60 b may also be connected to the third conductive line 60 c through the second connecting line 70 .

[0099] The third exemplary one is, Fig.11 As shown, there are four conductive wires 60, and the four conductive wires 60 are arranged along Fig.11 From left to right in the figure, there are the first conductive line 60a, the second conductive line 60b, the third conductive line 60c and the fourth conductive line 60d, there are two first connecting lines 50, and there is one second connecting line 70. The first conductive line 60a and the third conductive line 60c are connected through one first connecting line 50, and the third conductive line 60c and the fourth conductive line 60d are connected through one first connecting line 50 to form a series circuit. One end of the second conductive line 60b is connected to the first conductive line 60a through the second connecting line 70, and the other end of the second conductive line 60b is connected to the first connecting line 50 connected between the first conductive line 60a and the third conductive line 60c, so as to be connected in parallel to the third conductive line 60c to form the aforementioned conductive circuit.

[0100] It can be understood that in other embodiments, the other end of the second conductive line 60 b may also be connected to the first conductive line 60 a through the second connecting line 70 .

[0101] The fourth exemplary one is, Fig.12 As shown, there are five conductive wires 60, and the five conductive wires 60 are arranged along Fig.11From left to right in the figure, there are the first conductive line 60a, the second conductive line 60b, the third conductive line 60c, the fourth conductive line 60d and the fifth conductive line 60e, there are two first connecting lines 50, and there are four second connecting lines 70. The first conductive line 60a and the second conductive line 60b are connected through one first connecting line 50, and the second conductive line 60b and the third conductive line 60c are connected through one first connecting line 50 to form a series circuit, both ends of the fourth conductive line 60d are respectively connected in parallel to the third conductive line 60c through the second connecting line 70, and both ends of the fifth conductive line 60e are respectively connected in parallel to the fourth conductive line 60d through the second connecting line 70, to form the aforementioned conductive circuit.

[0102] It can be understood that in other embodiments, such as Fig.13 As shown, two ends of the fourth conductive line 60d are respectively connected in parallel to the third conductive line 60c through the second connecting line 70, and two ends of the fifth conductive line 60e are respectively connected in parallel to the third conductive line 60c through the second connecting line 70, forming the aforementioned conductive circuit.

[0103] In some embodiments, Fig.14 and Fig.15 As shown, when the number of conductive wires 60 is odd, such as three, five, seven, etc., any two adjacent conductive wires 60 are connected through a first connecting line 50, and the multiple conductive wires 60 at this time can be regarded as all connected in series.

[0104] It can be seen that when the number of the conductive wires 60 is at least five and the number is an odd number, for example, when the conductive wires 60 are five, seven, etc., some of the conductive wires 60 can be connected in series to form a series circuit, and the other part of the conductive wires 60 can be connected in parallel in the series circuit (such as Fig.13 As shown), all the conductive wires 60 may be connected in series to form a series circuit (as shown Fig.14 and Fig.15 shown).

[0105] Considering that after some of the conductive wires 60 are connected in series to form a series circuit, the impedance and heat generation can be increased. On this basis, the remaining conductive wires 60 are connected in parallel in the series circuit, which not only increases the number of conductive wires 60, but also reduces the impedance of the series circuit and reduces the heat generation. Therefore, in the present application, it is preferred that the conductive wire 60 is singular, and any two adjacent conductive wires 60 are connected through a first connecting wire 50 to form a series circuit. In this way, the number of conductive wires 60 can be reduced while ensuring the heat generation of multiple conductive wires 60, thereby saving costs.

[0106] In the present application, at least two first connection lines 50 include a first sub-connection line 51 and a second sub-connection line 52, wherein the first sub-connection line 51 is located on one side of the conductive line 60 along its line length direction, and the second sub-connection line 52 is located on the other side of the conductive line 60 along its line length direction.

[0107] In some embodiments, the electronic device 100 further includes a flexible circuit board 80, one end of which can be electrically connected to the secondary board 40 via a first connector (not shown), and the other end of the flexible circuit board 80 can be electrically connected to the main board 30 via a second connector (not shown), wherein both the first connector and the second connector can be board-to-board connectors. The connection between the flexible circuit board 80 and the secondary board 40 and the connection between the flexible circuit board 80 and the main board 30 can be realized in the above manner, so that the connection method between the flexible circuit board 80 and the secondary board 40 and the connection method between the flexible circuit board 80 and the main board 30 can be relatively simple and easy to operate.

[0108] An exemplary example is Fig.16 and Fig.17 As shown, the flexible circuit board 80 can be one piece, and the plurality of conductive wires 60 are all arranged on the flexible circuit board 80, that is, the plurality of conductive wires 60 are integrated on one flexible circuit board 80. During assembly, one end of the flexible circuit board 80 can be plugged into the sub-board 40, and the other end can be plugged into the main board 30, so that each conductive wire 60 can be electrically connected between the main board 30 and the sub-board 40, thereby improving the installation efficiency of the plurality of conductive wires 60.

[0109] In an exemplary embodiment, Fig.16 As shown, the first sub-connection line 51 and the second sub-connection line 52 can be arranged on the flexible circuit board 80; or Fig.17 As shown, the first sub-connection line 51 can be arranged on the main board 30, and the second sub-connection line 52 can be arranged on the sub-board 40. Of course, in other embodiments, the first sub-connection line 51 can be arranged on the main board 30, and the second sub-connection line 52 can be arranged on the flexible circuit board 80, or the first sub-connection line 51 can be arranged on the flexible circuit board 80, and the second sub-connection line 52 can be arranged on the sub-board 40.

[0110] Preferably, the first sub-connection line 51 is arranged on the main board 30, and the second sub-connection line 52 is arranged on the sub-board 40. Thus, the first sub-connection line 51 and the second sub-connection line 52 will not occupy the space of the flexible circuit board 80, so that the conductive line 60 can fully utilize the space of the flexible circuit board 80 to form a relatively long conductive line 60, which is conducive to further increasing the impedance of the conductive line and increasing the heat generation.

[0111] Another exemplary example is Fig.18 and Fig.19As shown, the flexible circuit board 80 can be multiple pieces, and the number of the flexible circuit board 80 is the same as the number of the conductive wires 60, wherein one conductive wire 60 is arranged on one flexible circuit board 80, so that the multiple conductive wires 60 can be dispersed at different positions of the battery 20, so that the heat generated by the conductive wires 60 when current is passed can be dispersed at different positions of the battery 20, avoiding the heat generated by the conductive wires 60 from being concentrated at a certain position of the battery 20, especially when the battery 20 is charged in a low temperature environment, the battery 20 can be evenly heated, so that the battery 20 is evenly heated, so that the temperature of the battery 20 can rise faster, so that the battery 20 can enter a large current charging state more quickly, thereby greatly improving the charging speed of the battery 20 and shortening the charging time.

[0112] In an exemplary embodiment, the first sub-connection line 51 is disposed on the main board 30, and the second sub-connection line 52 is disposed on the sub-board 40. Thus, the first sub-connection line 51 and the second sub-connection line 52 do not occupy the space of the flexible circuit board 80, so that the conductive line 60 can fully utilize the space of the flexible circuit board 80 to form a relatively long conductive line 60, which is conducive to further increasing the impedance of the conductive line and increasing the heat generation.

[0113] Optionally, multiple flexible circuit boards 80 can be evenly spaced along the circumference of the battery 20, so that when current is passed through the conductive wire 60, the battery 20 can be heated more evenly. In a low temperature environment, the temperature of the battery 20 can rise faster, so that the battery 20 can enter a state where it can be charged with a large current more quickly, thereby greatly improving the charging speed of the battery 20 and shortening the charging time, or allowing the battery 20 to recover to a state where it can output a large current more quickly to ensure that the electronic device 100 can operate normally.

[0114] It can be understood that when the multiple conductive wires 60 are all located on the side of the battery 20 facing the back cover 13, or are all located on the side of the battery 20 facing away from the back cover 13, the multiple flexible circuit boards 80 are evenly spaced along the circumference of the battery 20, then the multiple flexible circuit boards 80 are evenly spaced along the width direction of the electronic device 100.

[0115] In the above scheme, the applicant has found in practice that when charging the battery 20 in a low temperature environment, the current passing through the conductive circuit can accelerate the temperature rise of the battery, and as the charging time increases, the temperature of the battery 20 will gradually rise, allowing the battery 20 to enter a high current charging state, for example, the temperature of the battery 20 rises to the temperature required for the battery 20 to enter a fast charging state; or, when charging the battery 20 in a normal temperature environment or a high temperature environment, the battery 20 at this time can be charged with a large current. However, in the above process, not only will the battery 20 heat up significantly and generate a large amount of heat, but the conductive circuit will also heat up significantly and generate a large amount of heat when a large current passes through it, which makes it easier to cause the battery 20 or the entire device to be overheated, and then cause the electronic device 100 to heat up during charging, which brings a bad user experience, or triggers high temperature protection, affecting the charging speed of the electronic device 100.

[0116] In this regard, Figures 16 to 19 As shown, in some embodiments, the electronic device 100 further includes at least two switching switches 90 , the switching switches 90 are electrically connected between two adjacent conductive lines 60 , and the two adjacent switching switches 90 are respectively located on both sides of the conductive line 60 along its line length direction.

[0117] Among them, when the battery 20 is in a low temperature state, at least two switching switches 90 are disconnected, so that at least three conductive wires 60 are connected in series to form a series circuit, that is, the conductive circuit at least includes a series circuit, thereby increasing the impedance of the conductive circuit and increasing the heat generated by the conductive circuit when current is passed through it, so that the temperature of the battery 20 can be quickly heated up, so that the battery 20 can quickly enter a state that can support large current charging, which is beneficial to improve the charging speed; or the battery 20 can output a large current to support the normal operation and use of the electronic device 100 to avoid the electronic device 100 from shutting down.

[0118] When the battery 20 is at normal temperature or high temperature, or when the battery 20 is at a temperature that meets the fast charging requirements, for example, when the temperature of the battery 20 is higher than or equal to 20°C, and when the current is connected to the charging port 41, at least two switching switches 90 are closed to make the conductive circuit form a parallel circuit, so that the current entering through the charging port 41 can reach the parallel circuit and the connecting circuit 31 in turn, and reach the battery 20 through the connecting circuit 31 on the main board 30, so as to charge the battery 20.

[0119] The battery 20 being in a normal temperature state or a high temperature state can be understood as the state of the battery 20 in a normal temperature environment or a high temperature environment. When the battery 20 is in a normal temperature state, the temperature of the battery 20 is higher than or equal to 15°C and lower than or equal to 25°C, that is, the temperature of the battery 20 is in the range of 15°C-25°C; when the battery 20 is in a high temperature state, the temperature of the battery 20 is higher than 25°C, for example, the temperature of the battery 20 is in the range of 25°C-50°C.

[0120] Since the impedance of the parallel circuit formed by the multiple conductive wires 60 is much smaller than the impedance of a single conductive wire 60, the impedance is reduced. When charging with a large current, the overall heat generation of the multiple conductive wires 60 under the same current can be greatly reduced, and the heat generation is reduced. This can effectively improve the problem of heating during charging of the electronic device 100, and at the same time, it can also avoid the situation where the charging speed is affected by the excessive temperature of the battery 20 or the whole device, thereby improving the charging efficiency.

[0121] It can be seen that the present application sets at least two switching switches 90 to match the design of at least two first connecting lines 50 and at least three conductive lines 60. By controlling the on and off of the switching switches 90, the at least three conductive lines 60 can be switched between forming a series circuit and forming a parallel circuit, so as to facilitate adjusting the series-parallel relationship of the at least three conductive lines 60 according to the temperature of the battery 20. When the battery 20 is in a low temperature state, the at least three conductive lines 60 can be connected in series to form a series circuit, so as to utilize the characteristics of the series circuit having a large impedance and being able to generate a large amount of heat, so as to quickly heat the battery 20, so that the battery 20 can quickly enter a state supporting large current charging, so as to The charging speed of the battery 20 in a low temperature environment is improved, the charging time is shortened, or the battery 20 outputs a large current to ensure that the electronic device 100 can work normally, so as to improve the problem of abnormal shutdown of the electronic device 100 in a low temperature environment; and when the battery 20 is at room temperature or high temperature, multiple conductive wires 60 are connected in parallel to form a parallel circuit, so as to utilize the characteristics of the parallel circuit with small impedance and small heat generation. When charging the battery 20, the heat generation of the conductive circuit is reduced, thereby avoiding the problem of charging heating of the electronic device 100, and avoiding the situation where the charging speed is affected by the excessive temperature of the battery 20 or the whole device, so as to improve the charging efficiency.

[0122] In the present application, at least two switching switches 90 include a first switching switch 90a and a second switching switch 90b, the first switching switch 90a is located on one side of the conductive line 60 along its line length direction, the first switching switch 90a and the first sub-connection line 51 are located on the same side of the conductive line 60 along its line length direction, the second switching switch 90b is located on the other side of the conductive line 60 along its line length direction, the second switching switch 90b and the second sub-connection line 52 are located on the same side of the conductive line 60 along its line length direction, and the second switching switch 90b and the second sub-connection line 52 are located on the same side of the conductive line 60 along its line length direction.

[0123] Among them, Fig.16 As shown, the first switch 90a and the second switch 90b can be arranged on the flexible circuit board 80; or Figures 17 to 19 As shown, the first switch 90a can be arranged on the main board 30, and the second switch 90b can be arranged on the sub-board 40. Of course, in other embodiments, the first switch 90a can be arranged on the main board 30, and the second switch 90b can be arranged on the flexible circuit board 80, or the first switch 90a can be arranged on the flexible circuit board 80, and the second switch 90b can be arranged on the sub-board 40.

[0124] Considering that the main board 30 and the sub-board 40 are usually hard boards and the flexible circuit board 80 is a soft board, it is preferred to set the first switching switch 90a on the main board 30 and the second switching switch 90b on the sub-board 40, which can facilitate the installation and fixation of the first switching switch 90a and the second switching switch 90b.

[0125] When the number of the conductive wires 60 is at least five and the number of the first switches 90a is at least two, as shown in FIG. Fig. 20 As shown, each first switch 90a can be an independent switch, or, as shown in FIG. Fig.21 As shown, at least two first switching switches 90 are integrated into an integrated switch chip.

[0126] That is, an exemplary Fig.21 As shown, the number of the conductive wires 60 is five, the number of the first switching switches 90a is two, and the two first switching switches 90a can be integrated into an integrated switch chip; another exemplary embodiment, as shown in FIG. Fig. 22 As shown, the number of the conductive wires 60 is six, the number of the first switching switches 90a is two, and the two first switching switches 90a can be integrated into an integrated switch chip; another exemplary embodiment, as shown in FIG. Fig.23 As shown, the number of the conductive wires 60 is seven, and the number of the first switching switches 90 a is three. The three first switching switches 90 a can be integrated into an integrated switch chip.

[0127] Thus, compared to each first switch 90a being an independent switch, during assembly, a plurality of first switches 90a can be installed on the main board 30 at the same time, thereby improving the installation efficiency of the first switch 90a.

[0128] When the number of the conductive wires 60 is at least five, and the number of the second switches 90b is at least two, as shown in FIG. Fig. 20 As shown, each second switch 90b can be an independent switch, or, as shown in FIG. Fig.21 As shown, at least two second switching switches 90b are integrated into an integrated switch chip.

[0129] That is, an exemplary Fig.21 As shown, the number of the conductive wires 60 is five, the number of the second switching switches 90b is two, and the two second switching switches 90b can be integrated into an integrated switch chip; another exemplary embodiment, as shown in FIG. Fig. 22 As shown, the number of the conductive wires 60 is six, the number of the second switching switches 90b is two, and the two second switching switches 90b can be integrated into an integrated switch chip; another exemplary embodiment, as shown in FIG. Fig.23 As shown, the number of the conductive wires 60 is seven, and the number of the second switching switches 90 b is three. The three second switching switches 90 b can be integrated into an integrated switch chip.

[0130] Thus, compared to each second switch 90b being an independent switch, during assembly, a plurality of second switches 90b can be installed on the sub-board 40 at the same time, thereby improving the installation efficiency of the second switches 90b.

[0131] In some embodiments, Fig.24 As shown, a normally closed switch 53 is provided on the first connecting line 50. Therefore, when the temperature of the battery 20 is abnormally high during charging, the normally closed switch 53 is disconnected to suspend the charging of the battery 20, thereby preventing the battery 20 from overheating and leaking or even catching fire and exploding, thereby facilitating the use safety of the electronic device 100.

[0132] like Fig.25 As shown, the normally closed switch 53 includes a first sub-normally closed switch 53a, the first sub-normally closed switch 53a and the first switching switch 90a are located on the same side of the conductive line 60 along the line length direction thereof, and the first sub-normally closed switch 53a and the first switching switch 90a are integrated into an integrated switch chip. The integrated switch chip can be arranged on the flexible circuit board 80 or on the main board 30.

[0133] An exemplary example is Fig.25As shown, a first sub-normally closed switch 53a and a first switching switch 90a are integrated into an integrated switch chip, and the integrated switch chip is arranged on the main board 30; another exemplary embodiment, as shown Fig.26 As shown, the two first sub-normally closed switches 53 a and the two first switching switches 90 a are integrated into an integrated switch chip, and the integrated switch chip is arranged on the main board 30 .

[0134] In this way, compared with the first sub-normally closed switch 53a and the first switching switch 90a being independent switches, during assembly, the first sub-normally closed switch 53a and the first switching switch 90a can be installed on the main board 30 at the same time, thereby improving installation efficiency.

[0135] In some embodiments, Fig.25 As shown, the normally closed switch 53 further includes a second normally closed switch 53b, the first normally closed switch 53a and the second normally closed switch 53b are located on different sides of the conductive line 60 along the length direction thereof, the second normally closed switch 53b and the second switching switch 90b are located on the same side of the conductive line 60 along the length direction thereof, and the second normally closed switch 53b and the second switching switch 90b are integrated into an integrated switch chip. The integrated switch chip can be disposed on the flexible circuit board 80 or on the sub-board 40.

[0136] An exemplary example is Fig.25 As shown, a second normally closed sub-switch 53b and a second switching switch 90b are integrated into an integrated switch chip, and the integrated switch chip is arranged on the sub-board 40; another exemplary embodiment, as shown Fig.26 As shown, the two second sub-normally closed switches 53 b and the two second switching switches 90 b are integrated into an integrated switch chip, and the integrated switch chip is arranged on the main board 30 .

[0137] In this way, compared with the second sub-normally closed switch 53b and the second switching switch 90b being independent switches, during assembly, the second sub-normally closed switch 53b and the second switching switch 90b can be installed on the sub-board 40 at the same time, thereby improving the installation efficiency.

[0138] When the charger is inserted into the charging port 41 to charge the battery 20, the magnitude of the current flowing into the conductive circuit through the charging port 41 generally does not change with the change of the ambient temperature, and is generally constant and generally a large current. However, as mentioned above, when the battery 20 is in a low temperature state, the battery 20 can only support small current charging, that is, only a part of the current entering through the charging port 41 flows into the low-temperature battery 20, thereby resulting in an extra current.

[0139] In this regard, when the battery 20 is in a low temperature state and the charging port 41 is connected to current, the switching switch 90 is used to switch the multiple conductive wires 60 between forming a series circuit and forming a parallel circuit. At least one switching switch 90 is a single-pole double-throw switch, and the single-pole double-throw switch is used for grounding. Then, a large current flows in through the charging port 41, a part of which reaches the battery 20 through the series circuit and the connecting line 31, and the other part of the current is introduced into the ground through the switching switch 90. In this way, the excess current can be introduced into the ground, thereby avoiding leakage of the battery 20 when charging in a low temperature environment, so as to improve the safety of the battery 20 when charging in a low temperature environment.

[0140] In this application, if Fig.25 and Fig.26 As shown, at least three conductive wires 60 include a first sub-conductive wire 61 and a second sub-conductive wire 62, wherein one end of the first sub-conductive wire 61 is connected to the connection line 31, and the other end of the first sub-conductive wire 61 is connected to the first connection line 50, one end of the second sub-conductive wire 62 is connected to the charging port 41, and the other end of the second sub-conductive wire 62 is connected to the first connection line 50. At least two switches 90 include a first sub-switching switch 91 and a second sub-switching switch 92, the first sub-switching switch 91 is electrically connected between the first sub-conductive wire 61 and the conductive wire 60 adjacent thereto, and the second sub-switching switch 92 is electrically connected between the second sub-conductive wire 62 and the conductive wire 60 adjacent thereto.

[0141] In an exemplary embodiment, when the battery 20 is in a low temperature state and the charging port 41 is connected to current to charge the battery 20, so that the battery 20 is in a charging state, the first sub-switching switch 91 is a single-pole double-throw switch and is used for grounding. Then, the large current flowing in through the charging port 41 flows into the series circuit, and part of the current reaches the battery 20 through the connecting line 31, while the other part of the current is introduced into the ground through the first sub-switching switch 91. In this way, the excess current can be introduced into the ground, thereby avoiding leakage of the battery 20 when charging in a low temperature environment, so as to improve the safety of the battery 20 when charging in a low temperature environment.

[0142] Another exemplary embodiment is that when the battery 20 is in a low temperature state and the charging port 41 is connected to the current to charge the battery 20, so that the battery 20 is in a charging state, the second sub-switching switch 92 is a single-pole double-throw switch and is used for grounding. Then, a large current flows in through the charging port 41, a part of which reaches the battery 20 through the series line and the connecting line 31, and the other part of the current is introduced into the ground through the second sub-switching switch 92. In this way, the excess current can be introduced into the ground, thereby avoiding leakage of the battery 20 when charging in a low temperature environment, so as to improve the safety of the battery 20 when charging in a low temperature environment.

[0143] It can be seen that when the battery 20 is in a low temperature state and the charging port 41 is connected to the current to charge the battery 20, so that the battery 20 is in a charging state, the second sub-switching switch 92 is used for grounding. Since the current is shunted before flowing into the series circuit, the current flowing into the series circuit becomes smaller. The first sub-switching switch 91 is used for grounding. Since the current is shunted after flowing into the series circuit, the current flowing into the series circuit is relatively large, so that the series circuit can generate greater heat, thereby heating the battery 20 faster, allowing the temperature of the battery 20 to rise rapidly, and then further accelerating the speed at which the battery 20 enters a state capable of high current charging, thereby greatly improving the charging speed of the battery 20 and shortening the charging time.

[0144] It is understandable that when the battery 20 is in a normal temperature state or a high temperature state, neither the first sub-switch 91 nor the second sub-switch 92 is used for grounding to avoid current shunting, thereby ensuring the charging speed of the battery 20.

[0145] In an exemplary embodiment, when the battery 20 is in a low temperature state and the OTG function of the electronic device 100 is used to put the battery 20 in a discharge state, the second sub-switch 92 is a single-pole double-throw switch and is used for grounding, and the current output by the battery 20 can flow into the series circuit through the connecting line 31, and finally be introduced into the ground through the second sub-switch 92. In this process, the series circuit is passed with current, which can generate a large amount of heat, thereby heating the battery 20, thereby increasing the temperature of the battery 20 and improving the low-temperature discharge state of the battery 20.

[0146] In another exemplary embodiment, when the battery 20 is in a low temperature state, and the OTG function of the electronic device 100 is used to put the battery 20 in a discharge state, the charging port 41 is used to output current. For example, the charging port 41 is plugged with an external device such as a USB flash disk (short for USB flash disk), a mobile hard disk, etc., and the current output by the battery 20 can flow into the series circuit through the connecting line 31, and finally output to the external device such as the USB flash disk, the mobile hard disk, etc. through the charging port 41. In this process, the series circuit is passed with current, which can generate a large amount of heat to heat the battery 20, so that the temperature of the battery 20 can be increased, and the low-temperature discharge state of the battery 20 can be improved.

[0147] It can be seen that when the battery 20 is in a low temperature state and the OTG function of the electronic device 100 is used to put the battery 20 in a discharging state, compared with the method of using the charging port 41 to plug in external devices such as a USB flash drive and a mobile hard disk, the second sub-switch 92 is used for grounding, and there is no need to carry external devices such as a USB flash drive and a mobile hard disk all the time, so that the discharge method of the battery 20 can be more flexible and convenient.
