[0023] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0024] The disclosure below provides many different embodiments or examples to implement different structures of the present disclosure. In order to simplify the disclosure of the present disclosure, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present disclosure. In addition, the present disclosure can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present disclosure provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0025] When charging, some electronic devices in the related art first have the current from the power interface reach the sub-board, then be transmitted from the sub-board to the main board through a flexible circuit board, and then be transmitted from the main board to the battery through another flexible circuit board. The charging path is long. When these electronic devices use the method of increasing the current for fast charging, the current flow path is long and the current flow is large, which can easily cause current loss, causing the heat generated by the electronic device during charging to increase, reducing the charging efficiency, and at the same time, it may also burn the electronic device, or even cause safety accidents, such as causing the electronic device to catch fire, the battery to explode, and other dangers. To this end, the present disclosure proposes an electronic device 100. The electronic device 100 of the embodiment of the present disclosure has the advantages of short charging path, low heat generation, high charging efficiency, and high safety.

[0026] Hereinafter, referring to the drawings, an electronic device 100 according to an embodiment of the present disclosure will be described.

[0027] like Figure 1As shown, the electronic device 100 according to the embodiment of the present disclosure may include: a housing 1, a battery 2 and a circuit board assembly 3, wherein the housing 1 has a power interface 10, the battery 2 is arranged in the housing 1 and includes a battery protection board 21 and a battery cell 22, and the circuit board assembly 3 is arranged in the housing 1 and is electrically connected to the power interface 10. Therefore, when the power interface 10 is connected to a power socket through a power cord and a power plug, the battery 2 can be charged.

[0028] like Figure 1 As shown, the circuit board assembly 3 may include a main board 31, a sub-board 32, a first flexible circuit board 33 and a second flexible circuit board 34, wherein the main board 31 and the sub-board 32 are arranged along a first direction (eg Figure 1 The main board 31 and the auxiliary board 32 are respectively located on both sides of the battery 2, and the battery protection board 21 and the battery cell 22 are arranged in a second direction perpendicular to the first direction (such as Figure 1 The first flexible circuit board 33 connects the battery protection board 21 and the main board 31, and the second flexible circuit board 34 connects the battery protection board 21 and the auxiliary board 32.

[0029] That is to say, the battery 2 is sandwiched between the main board 31 and the sub-board 32, and the battery protection board 21 is located on the side of the battery cell 22, rather than the battery protection board 21 being located on the side of the battery cell 22 close to the main board 31, or the battery protection board 21 being located on the side of the battery cell 22 close to the sub-board 32, so that the length of the first flexible circuit board 33 connecting the main board 31 and the battery protection board 21 can be shorter, and the length of the second flexible circuit board 34 connecting the sub-board 32 and the battery protection board 21 can also be shorter.

[0030] Therefore, by arranging the battery protection board 21 on the side of the battery cell 22, and using the first flexible circuit board 33 to connect the battery protection board 21 and the main board 31, and using the second flexible circuit board 34 to connect the battery protection board 21 and the sub-board 32, the current transmission path between the battery 2 and the main board 31, and the current transmission path between the battery 2 and the sub-board 32 can be effectively shortened. Therefore, whether the main board 31 and the first flexible circuit board 33 are used to charge the battery 2, or the sub-board 32 and the second flexible circuit board 34 are used to charge the battery 2, the charging path can be effectively shortened, the charging heat, charging efficiency and charging safety can be improved, and when one of the first flexible circuit board 33 and the second flexible circuit board 34 is used to charge the battery 2, the other of the first flexible circuit board 33 and the second flexible circuit board 34 can also be used to discharge the battery 2, thereby meeting the power supply requirements and ensuring that the electronic device 100 can work normally.

[0031] For example, Figure 1 and Figure 2In the example shown, the length direction of the battery protection board 21 is from the main board 31 to the auxiliary board 32, that is, the main board 31 and the auxiliary board 32 are connected along the length direction of the battery protection board 21 (such as Figure 1 The main board 31 and the auxiliary board 32 are arranged at two sides of the battery 2, respectively. The first flexible circuit board 33 is connected between the battery protection board 21 and the main board 31, and the second flexible circuit board 34 is connected between the battery protection board 21 and the auxiliary board 32. Therefore, since the main board 31 and the auxiliary board 32 are respectively located on both sides of the length of the battery protection board 21, the length of the battery protection board 21 (for example Figure 1 The upper end of the battery protection board 21 shown in FIG. 3 ) can be close to the main board 31, while the other end of the length of the battery protection board 21 (e.g. Figure 1 The lower end of the battery protection plate 21 shown in the figure can be close to the sub-plate 32, thereby effectively shortening the current transmission path.

[0032] For example, in some specific examples of the present disclosure, the power interface 10 is connected to the sub-board 32. At this time, the second flexible circuit board 34 can be used as the sub-board 32 to charge the battery 2, and the first flexible circuit board 33 can be used as the battery 2 to discharge the main board 31. Moreover, in this example, there are multiple ways for the sub-board 32 to obtain the discharge of the battery 2. For example, when the power interface 10 is not connected to the power socket, the battery 2 can also use the second flexible circuit board 34 to discharge to the sub-board 32; for example, when the circuit board assembly 3 includes the adapter board 30 connecting the main board 31 and the sub-board 32 as described later, the adapter board 30 can also be used so that the electricity discharged by the battery 2 to the main board 31 can also be transmitted to the sub-board 32 through the adapter board 30.

[0033] This shows that by placing the battery protection board 21 on the side of the battery 2, so that the main board 31 and the sub-board 32 are respectively located on both sides of the length of the battery protection board 21, the battery protection board 21 can extend two flexible circuit boards, namely a first flexible circuit board 33 for connecting to the main board 31, and a second flexible circuit board 34 for connecting to the sub-board 32. In this way, when the sub-board 32 is connected to the power interface 10, the second flexible circuit board 34 can be used as a charging flexible circuit board, which is connected to the power interface 10 through the sub-board 32 to charge the battery 2, and the first flexible circuit board 33 can be used as a discharge flexible circuit board so that the battery 2 supplies power to the main board 31. Similarly, when the main board 31 is connected to the power interface 10, the first flexible circuit board 33 can be used as a charging flexible circuit board, which is connected to the power interface 10 through the main board 31 to charge the battery 2, and the second flexible circuit board 34 can be used as a discharge flexible circuit board so that the battery 2 supplies power to the sub-board 32.

[0034] The calculation formula for the heat loss during the charging process of battery 2 is: P = I 2R, wherein I is the charging current and R is the loop impedance. Since the present disclosure can shorten the length of the flexible circuit board used to charge the battery 2, the charging loop impedance R can be reduced. The amount of reduction in R is related to the length of the battery 2, thereby achieving the purpose of reducing heat loss and improving charging efficiency, and the effect is more significant for large current charging conditions.

[0035] In short, according to the electronic device 100 of the embodiment of the present disclosure, since the main board 31 and the sub-board 32 are respectively arranged on both sides of the length of the battery protection board 21, that is, the battery 2 is placed on its side between the main board 31 and the sub-board 32, and a first flexible circuit board 33 and a second flexible circuit board 34 are arranged, the charging path can be shortened to reduce charging heat and improve user experience.

[0036] It should be noted that the composition and function of the "battery protection board 21" are well known to those skilled in the art, that is, an integrated circuit board that protects the rechargeable battery 2, such as a lithium battery. For example, the rechargeable lithium battery needs protection because of its own characteristics. Since the material of the lithium battery itself determines that it cannot be overcharged, over-discharged, over-currented, short-circuited, or charged and discharged at ultra-high temperatures, the lithium battery will always be accompanied by a protection board with a sampling resistor and a current fuse. Therefore, no further description is given here.

[0037] In addition, after the specific type of the electronic device 100 is determined, the specific structure and function of the "main board 31" and the "sub-board 32" are also well known to those skilled in the art. For example, when the electronic device 100 is a smart phone, those skilled in the art can clearly understand what the "main board 31" and the "sub-board 32" refer to respectively. Of course, the electronic device 100 according to the embodiment of the present disclosure is not limited to a smart phone, for example, it can also be a tablet computer, a car computer, etc., which is not limited here.

[0038] It should be noted that there may be one or more battery cells 22, and the battery protection board 21 is connected to the tabs of each battery cell 22. In some embodiments of the present disclosure, the battery 2 may have only one battery cell 22; in other embodiments of the present disclosure, the battery 2 may also have multiple battery cells 22, and the multiple battery cells 22 may be connected in series and / or in parallel, that is, the multiple battery cells 22 may be connected in series, or the multiple battery cells 22 may be connected in parallel, or the multiple battery cells 22 may be connected in series first and then in parallel, or the multiple battery cells 22 may be connected in parallel first and then in series, etc. In this way, different practical requirements can be met.

[0039] In some embodiments of the present disclosure, the circuit board assembly 3 may include an adapter board 30, which connects the main board 31 and the sub-board 32. Thus, when the battery 2 discharges to the main board 31 through the first flexible circuit board 33, the main board 31 can discharge to the sub-board 32 through the adapter board 30. When the battery 2 discharges to the sub-board 32 through the second flexible circuit board 34, the sub-board 32 can discharge to the main board 31 through the adapter board 30, so that the electronic device 100 can work normally.

[0040] In some specific examples of the present disclosure, such as Figure 1 As shown, the adapter board 30 may include a rigid circuit board 35, the rigid circuit board 35 connects the main board 31 and the auxiliary board 32, and the rigid circuit board 35 is located on a side of the battery 2 away from the battery protection board 21. Figure 1 In the example shown, when the battery protection board 21 is located on the right side of the battery 2, the rigid circuit board 35 is located on the left side of the battery 2, so that the space can be more fully utilized and the assembly is convenient.

[0041] In some specific examples of the present disclosure, Figure 2 As shown, the adapter board 30 may include a third flexible circuit board 36, the third flexible circuit board 36 connects the main board 31 and the sub-board 32, and the third flexible circuit board 36 is arranged on the thickness side of the battery 2. Thus, more accommodation space can be reserved for the battery 2, so that the capacity of the battery 2 can be larger, meeting a longer standby time.

[0042] In some embodiments, Figure 1 As shown, the battery protection board 21 is arranged on the side between the main board 31 and the sub-board 32. The meaning of "the side between the main board 31 and the sub-board 32" is explained below, that is, the length direction of the battery protection board 21 is defined as the first direction F1, the first direction F1 is perpendicular to the second direction F2, the two ends of the main board 31 in the second direction F2 are the first end and the second end, the two ends of the sub-board 32 in the second direction F2 are the third end and the fourth end respectively, the first end and the third end are arranged relatively along the first direction F1, and the second end and the fourth end are arranged relatively along the first direction F1, and the battery protection board 21 is arranged between the first end and the third end, or between the second end and the fourth end, that is, the battery protection board 21 is arranged close to the side between the main board 31 and the sub-board 32, so as to increase the accommodating space of the battery cell 22 and improve the capacity and endurance of the battery 2.

[0043] like Figure 1As shown, the first flexible circuit board 33 is connected to the side of the main board 31 close to the battery protection board 21, and the second flexible circuit board 34 is connected to the side of the sub-board 32 close to the battery protection board 21. As a result, the length of the first flexible circuit board 33 and the length of the second flexible circuit board 34 can be further shortened, thereby shortening the charging path to reduce charging heat and improve user experience. Figure 1 In the example shown, when the battery protection board 21 is arranged on the right side between the main board 31 and the sub-board 32, the first flexible circuit board 33 is connected to the right end of the main board 31, and the second flexible circuit board 34 is connected to the right end of the sub-board 32.

[0044] like Figure 1 As shown, the first flexible circuit board 33 and the second flexible circuit board 34 are respectively connected to the two ends of the length of the battery protection board 21, thereby further shortening the length of the first flexible circuit board 33 and the length of the second flexible circuit board 34, thereby shortening the charging path to reduce charging heat and improve user experience. Figure 1 In the specific example shown in , the length direction F1 of the battery protection board 21 is the up-down direction, the first flexible circuit board 33 can be connected to the upper end of the battery protection board 21, and the second flexible circuit board 34 can be connected to the lower end of the battery protection board 21. Of course, the present disclosure is not limited to this, and the first flexible circuit board 33 and the second flexible circuit board 34 can also be connected to other parts of the battery protection board 21 respectively to better meet different practical requirements.

[0045] In some embodiments, Figure 1 As shown, the length direction of the battery protection plate 21 (for example Figure 1 The F1 direction shown in FIG. 1 may be the length direction of the electronic device 100. Therefore, for most electronic devices 100, there is no need to significantly improve the structure of the main board 31 and the sub-board 32, nor the overall layout of the electronic device 100, thereby facilitating mass production and reducing production costs.

[0046] In some embodiments, Figure 1 As shown, the housing 1 may include a first side 11 and a second side 12 that are arranged oppositely and in parallel, and a third side 13 and a fourth side 14 that are arranged oppositely and in parallel, the first side 11 and the second side 12 are arranged on both sides of the length of the third side 13 and the fourth side 14, respectively, the main board 31 is arranged on a side of the sub-board 32 close to the first side 11, the sub-board 32 is arranged on a side of the main board 31 close to the second side 12, and the battery protection board 21 is arranged parallel to the third side 13 and the fourth side 14. Therefore, the structure of the housing 1 is simple, convenient for production and processing, and convenient for assembly of the main board 31, the sub-board 32 and the battery 2.

[0047] It should be noted that the number and specific location of the power interfaces 10 are not limited. The specific locations of some optional power interfaces 10 of the present disclosure will be described below, but the present disclosure is not limited to the following examples.

[0048] For example, in Figure 1 In the example shown, the power interface 10 may include a first sub-power interface 101 provided on the first side 11, and the first sub-power interface 101 is electrically connected to the main board 31 to charge the battery 2 through the first flexible circuit board 33. That is, when the first sub-power interface 101 is connected to the power socket, the main board 31 can charge the battery 2 through the first flexible circuit board 33, and the battery 2 can discharge to the sub-board 32 through the second flexible circuit board 34. Thus, since the first side 11 is close to the main board 31, the distance between the first sub-power interface 101 and the main board 31 can be shortened, and the charging path can be further shortened to reduce charging heat and improve user experience.

[0049] For example, in Figure 1 In the example shown, the power interface 10 may include a second sub-power interface 102 provided on the second side 12, and the second sub-power interface 102 is electrically connected to the sub-board 32 to charge the battery 2 through the second flexible circuit board 34. That is, when the second sub-power interface 102 is connected to the power socket, the sub-board 32 can charge the battery 2 through the second flexible circuit board 34, and the battery 2 can discharge to the main board 31 through the first flexible circuit board 33. Therefore, since the distance between the second side 12 and the sub-board 32 is relatively close, the distance between the second sub-power interface 102 and the sub-board 32 can be shortened, and the charging path can be further shortened to reduce charging heat and improve user experience.

[0050] For example, in Figure 1 In the example shown, the power interface 10 may include a third sub-power interface 103 provided on the third side 13, and the third sub-power interface 103 falls on the positive projection area of ​​the mainboard 31 on the third side 13 (for example Figure 1In the A area shown in the figure, the third sub-power interface 103 is electrically connected to the mainboard 31 to charge the battery 2 through the first flexible circuit board 33. That is to say, when the third sub-power interface 103 is connected to the power socket, the mainboard 31 can charge the battery 2 through the first flexible circuit board 33, and the battery 2 can discharge to the sub-board 32 through the second flexible circuit board 34. Therefore, since the distance between the third sub-power interface 103 and the mainboard 31 is relatively close, the charging path can be further shortened to reduce charging heat and improve user experience. Moreover, in this embodiment, if the distance L1 between the battery protection board 21 and the third side 13 is less than the distance L2 between the battery protection board 21 and the fourth side 14, the distance between the first flexible circuit board 33 and the third sub-power interface 103 can be further shortened, thereby shortening the length of the power transfer from the third sub-power interface 103 to the first flexible circuit board 33, thereby further shortening the charging path to reduce charging heat and improve user experience.

[0051] For example, in Figure 1 In the example shown, the power interface 10 may include a fourth sub-power interface 104 disposed on the third side 13, and the fourth sub-power interface 104 falls on the positive projection area of ​​the secondary board 32 on the fourth side 14 (for example Figure 1 In the B area shown in the figure, the fourth sub-power interface 104 is electrically connected to the auxiliary board 32 to charge the battery 2 through the second flexible circuit board 34. That is to say, when the fourth sub-power interface 104 is connected to the power socket, the auxiliary board 32 can charge the battery 2 through the second flexible circuit board 34, and the battery 2 can discharge to the main board 31 through the first flexible circuit board 33. Therefore, since the fourth sub-power interface 104 is close to the auxiliary board 32, the charging path can be further shortened to reduce charging heat and improve user experience. Moreover, in this embodiment, if the distance L1 between the battery protection board 21 and the third side 13 is less than the distance L2 between the battery protection board 21 and the fourth side 14, the distance between the second flexible circuit board 34 and the fourth sub-power interface 104 can be further shortened, thereby shortening the length of the power transfer from the fourth sub-power interface 104 to the second flexible circuit board 34, thereby further shortening the charging path to reduce charging heat and improve user experience.

[0052] In a specific embodiment of the present disclosure, the battery 2 is set to a structure in which the battery protection board 21 is placed sideways, and at the same time, a first flexible circuit board 33 and a second flexible circuit board 34 connected to the main board 31 are extended from both ends of the battery protection board 21, and the power interface 10 is set at a position close to the auxiliary board 32. The auxiliary board 32 charges the battery 2 through the second flexible circuit board 34, and the battery 2 discharges to the main board 31 through the first flexible circuit board 33, thereby shortening the charging path and improving the charging effect. In addition, in the embodiment of the present disclosure, the power interface 10 can be set at the bottom, side, or even top of the electronic device 100, thereby shortening the charging path, reducing charging heat, and improving the user experience. Moreover, in the embodiment of the present disclosure, the main board 31 and the auxiliary board 32 can be set in a separate form through the third flexible circuit board 36, or can be set in an integral form through the rigid circuit board 35, without limitation.

[0053] In a specific example of the present disclosure, Figure 1 and Figure 2 As shown, the electronic device 100 includes: a shell 1, a battery 2, and a circuit board assembly 3. The shell 1 includes a first side 11 and a second side 12 that are arranged oppositely and in parallel, and a third side 13 and a fourth side 14 that are arranged oppositely and in parallel. The first side 11 is perpendicular to the third side 13, and the second side 12 has a power interface 10. The battery 2 is arranged in the shell 1. The battery 2 includes a battery protection board 21 and a battery cell 22. The battery protection board 21 is arranged on a side of the battery cell 22 close to the third side 13 or the fourth side 14. The circuit board assembly 3 is arranged in the shell 1 and is electrically connected to the power interface 10. The circuit board assembly 3 includes a main board 31, a sub-board 32, a first flexible circuit board 33 and a second flexible circuit board 34. The main board 31 is arranged on a side of the battery 2 close to the first side 11, and the sub-board 32 is arranged on a side of the battery 2 close to the second side 12. The first flexible circuit board 33 connects the battery protection board 21 and the main board 31, and the second flexible circuit board 34 connects the battery protection board 21 and the sub-board 32. Therefore, in this embodiment, the battery protection board 21 is disposed on the side of the electronic device 100, thereby ensuring that the structure of the electronic device 100 is simple and the charging path is short.

[0054] Of course, the present disclosure is not limited thereto. In other examples of the present disclosure, the battery protection board 21 may also be disposed at other locations of the electronic device 100, such as at Figure 3 In the example shown, the battery protection board 21 can be disposed between the rigid circuit board 35 and the battery cell 22. Figure 4 In the example shown, the battery protection board 21 may be disposed between two battery cells 22 , located at the center of the electronic device 100 , etc., which will not be elaborated here.

[0055] In addition, other structures and operations of the electronic device 100 according to the embodiment of the present disclosure are known to ordinary technicians in the field after the type of the electronic device 100 is determined, and will not be described in detail here.
