The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The following disclosure provides many different embodiments, or examples, for implementing different features of the disclosure. To simplify the disclosure of the present disclosure, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present disclosure. Further, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

When some electronic devices in the related art are charged, current firstly reaches the secondary board from the power interface, then is conveyed to the main board from the secondary board through the flexible circuit board, and then is conveyed to the battery from the main board through the other flexible circuit board, the charging path is long, when the electronic devices are rapidly charged in a manner of increasing the current, as the flowing path of the current is long, and the flow of the current is large, current loss is easily caused, the calorific value of the electronic devices during charging is increased, the charging efficiency is reduced, meanwhile, the electronic devices can be burnt, even safety accidents are caused, for example, dangers such as fire, battery explosion and the like of the electronic devices are caused. Therefore, the electronic device 100 has the advantages of short charging path, low heat generation amount, high charging efficiency, high safety and the like.

Next, an electronic apparatus 100 according to an embodiment of the present disclosure is described with reference to the drawings.

As shown in fig. 1, an electronic device 100 according to an embodiment of the present disclosure may include: the battery protection device comprises a shell 1, a battery 2 and a circuit board assembly 3, wherein the shell 1 is provided with a power interface 10, the battery 2 is arranged in the shell 1 and comprises a battery protection plate 21 and a battery core 22, and the circuit board assembly 3 is arranged in the shell 1 and is electrically connected with the power interface 10. Thus, when the power source interface 10 is connected to the power outlet via the power cord and the power plug, the battery 2 can be charged.

As shown in fig. 1, 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 at intervals along a first direction (e.g., an F1 direction shown in fig. 1), the main board 31 and the sub-board 32 are respectively located at two sides of the battery 2, the battery protection board 21 and the battery cell 22 are sequentially arranged along a second direction (e.g., an F2 direction shown in fig. 1) perpendicular to the first direction, 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.

That is, the battery 2 is interposed between the main board 31 and the sub-board 32, and the battery protection board 21 is located at a side portion of the battery cell 22, instead of the battery protection board 21 being located at a side of the battery cell 22 close to the main board 31, or the battery protection board 21 being located at a 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 short, and the length of the second flexible circuit board 34 connecting the sub-board 32 and the battery protection board 21 can also be short.

Thus, by disposing the battery protection plate 21 at the side of the battery core 22, and connecting the battery protection plate 21 and the main board 31 using the first flexible circuit board 33, and connecting the battery protection plate 21 and the sub-board 32 using the second flexible circuit board 34, it is possible to effectively shorten 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, so that it is possible to effectively shorten the charging path, improve the heat generation of charge, the charging efficiency, and the charging safety, regardless of whether the battery 2 is charged using the main board 31 and the first flexible circuit board 33, or the battery 2 is charged using the sub-board 32 and the second flexible circuit board 34, and, when the battery 2 is charged using one of the first flexible circuit board 33 and the second flexible circuit board 34, it is also possible to discharge the battery 2 using the other one of the first flexible circuit board 33 and the second flexible circuit board 34, thereby satisfying the power supply requirement and ensuring that the electronic device 100 can work normally.

For example, in the example shown in fig. 1 and 2, the length direction of the battery protection board 21 is a direction from the main board 31 to the sub-board 32, that is, the main board 31 and the sub-board 32 are distributed at intervals along the length direction of the battery protection board 21 (the direction of F1 shown in fig. 1), the main board 31 and the sub-board 32 are respectively provided on both sides of the battery 2, 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 sub-board 32. Thus, since the main plate 31 and the sub-plate 32 are respectively located at both sides of the length of the battery protection plate 21, one end of the length of the battery protection plate 21 (e.g., the upper end of the battery protection plate 21 shown in fig. 1) can be close to the main plate 31, while the other end of the length of the battery protection plate 21 (e.g., the lower end of the battery protection plate 21 shown in fig. 1) can be close to the sub-plate 32, so that the current transmission path can be effectively shortened.

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 may be used as the sub board 32 to charge the battery 2, the first flexible circuit board 33 may be used as the battery 2 to discharge the main board 31, and in this example, there are various 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 a power socket, the battery 2 may discharge to the sub board 32 by using the second flexible circuit board 34 at the same time; for another example, when the circuit board assembly 3 includes an adapter board 30 that connects the main board 31 and the sub-board 32, which will be described later, the adapter board 30 may be used to transmit the power discharged from the battery 2 to the main board 31 to the sub-board 32 through the adapter board 30.

It is explained that the battery protection board 21 is placed 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, so that the battery protection board 21 can extend out of two flexible circuit boards, namely, a first flexible circuit board 33 for connecting with the main board 31 and a second flexible circuit board 34 for connecting with the sub board 32, so that when the sub board 32 is connected with the power interface 10, the second flexible circuit board 34 can be used as a charging flexible circuit board to charge the battery 2 through the sub board 32 and the power interface 10, and the first flexible circuit board 33 can be used as a discharging flexible circuit board to supply power to the main board 31, and similarly, when the main board 31 is connected with the power interface 10, the first flexible circuit board 33 can be used as a charging flexible circuit board to charge the battery 2 through the main board 31 and the power interface 10, the second flexible circuit board 34 may serve as a discharging flexible circuit board for the battery 2 to supply power to the sub-board 32.

The calculation formula of the heat loss due to the charging process of the battery 2 is: p ═ I²R, wherein, I is charging current, and R is the return circuit impedance, because this disclosure can shorten the length that is used for the flexible circuit board to battery 2 charges to can reduce charging circuit impedance R, the volume that R reduces is relevant with battery 2's length, thereby can reach and reduce the loss of generating heat, promote charging efficiency's purpose, the effect to the heavy current charging condition is more showing.

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 disposed at two sides of the length of the battery protection board 21, that is, the battery 2 side is disposed between the main board 31 and the sub board 32, and the first flexible circuit board 33 and the second flexible circuit board 34 are disposed, the charging path can be shortened, the heat generated during charging can be reduced, and the user experience can be improved.

It should be noted that the structure and function of the "battery protection board 21" are well known to those skilled in the art, that is, the integrated circuit board for protecting the rechargeable battery 2, such as a lithium battery, is determined by its own characteristics, and since the material of the lithium battery determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited, and super-high temperature charging and discharging, the lithium battery always follows a protection board with a sampling resistor and a current protector. Therefore, it will not be described in detail here.

It should be noted that there may be one or more battery cells 22, and the battery protection plate 21 is connected to the tab of each battery cell 22.

Thereby, different practical requirements can be met.

In some embodiments of the present disclosure, the circuit board assembly 3 may include an adapter board 30, and the adapter board 30 connects the main board 31 and the sub board 32, so that when the battery 2 discharges to the main board 31 through the first flexible circuit board 33, the main board 31 may discharge to the sub board 32 through the adapter board 30, and when the battery 2 discharges to the sub board 32 through the second flexible circuit board 34, the sub board 32 may discharge to the main board 31 through the adapter board 30, thereby enabling the electronic device 100 to operate normally.

In some specific examples of the present disclosure, as shown in fig. 1, the interposer 30 may include a rigid circuit board 35, the rigid circuit board 35 connects the main board 31 and the sub-board 32, and the rigid circuit board 35 is located on a side of the battery 2 away from the battery protection board 21. For example, in the example shown in fig. 1, when the battery protection plate 21 is positioned on the right side of the battery 2, the rigid circuit board 35 is positioned on the left side of the battery 2, so that space can be more fully utilized and assembly is facilitated.

In some specific examples of the present disclosure, as shown in fig. 2, the interposer 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 provided on the thickness side of the battery 2. Therefore, more accommodating space can be reserved for the battery 2, so that the capacity of the battery 2 can be larger, and the longer standby time can be met.

In some embodiments, as shown in fig. 1, the battery protection board 21 is provided at a side portion between the main board 31 and the sub-board 32. In the following, the meaning of "the side portion between the main plate 31 and the sub-plate 32" is explained, that is, the length direction of the battery protection plate 21 is defined as a first direction F1, the first direction F1 is perpendicular to a second direction F2, two ends of the main plate 31 in the second direction F2 are a first end and a second end, two ends of the sub-plate 32 in the second direction F2 are a third end and a fourth end, respectively, the first end and the third end are disposed opposite to each other along the first direction F1, the second end and the fourth end are disposed opposite to each other along the first direction F1, and the battery protection plate 21 is disposed between the first end and the third end or between the second end and the fourth end, that is, the battery protection plate 21 is disposed close to the side edge between the main plate 31 and the sub-plate 32, so that the accommodation space of the battery cell 22 can be increased and the capacity and the.

As shown in fig. 1, the first flexible circuit board 33 is connected to a side of the main board 31 near the battery protection board 21, and the second flexible circuit board 34 is connected to a side of the sub-board 32 near the battery protection board 21. From this, can further shorten the length of first flexible circuit board 33 to and shorten the length of second flexible circuit board 34, thereby can shorten the route of charging, with reduce to charge and generate heat, promote user experience. For example, in the example shown in fig. 1, when the battery protection board 21 is provided at the right side portion between the main board 31 and the sub-board 32, the first flexible circuit board 33 is connected to the right end portion of the main board 31, and the second flexible circuit board 34 is connected to the right end portion of the sub-board 32.

As shown in fig. 1, the first flexible circuit board 33 and the second flexible circuit board 34 are respectively connected to two ends of the length of the battery protection board 21, so that the length of the first flexible circuit board 33 can be further shortened, the length of the second flexible circuit board 34 can be shortened, a charging path can be shortened, heat generated during charging can be reduced, and user experience can be improved. For example, in the specific example shown in fig. 1, the length direction F1 of the battery protection board 21 is an up-down direction, the first flexible circuit board 33 may be connected to the upper end of the battery protection board 21, and the second flexible circuit board 34 may be connected to the lower end of the battery protection board 21. Of course, the present disclosure is not limited thereto, and the first flexible circuit board 33 and the second flexible circuit board 34 may also be respectively connected with other portions of the battery protection board 21 to better meet different practical requirements.

In some embodiments, as shown in fig. 1, a length direction of the battery protection plate 21 (e.g., the direction of F1 shown in fig. 1) may be a length direction of the electronic apparatus 100. Therefore, for most of the electronic devices 100, the structural form of the main board 31 and the sub-board 32 does not need to be greatly improved, and the overall layout of the electronic device 100 does not need to be greatly improved, so that the mass production is facilitated, and the production cost is reduced.

In some embodiments, as shown in fig. 1, the housing 1 may include a first side 11 and a second side 12 disposed opposite and in parallel, and a third side 13 and a fourth side 14 disposed opposite and in parallel, the first side 11 and the second side 12 are respectively disposed at two sides of a length of the third side 13 and the fourth side 14, the main plate 31 is disposed at a side of the sub plate 32 close to the first side 11, the sub plate 32 is disposed at a side of the main plate 31 close to the second side 12, and the battery protection plate 21 is disposed parallel to the third side 13 and the fourth side 14. Thus, the housing 1 is simple in structure, convenient to produce and process, and facilitates assembly of the main plate 31, the sub-plate 32, and the battery 2.

It should be noted that the number and specific arrangement positions of the power interfaces 10 are not limited, and specific positions 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.

For example, as shown in fig. 1, the power interface 10 may include a first sub power interface 101 disposed 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 a power outlet, the main board 31 may charge the battery 2 through the first flexible circuit board 33, and the battery 2 may discharge the sub board 32 through the second flexible circuit board 34. From this, because first side 11 is nearer with mainboard 31's distance to can shorten first sub power source 101 to the distance between the mainboard 31, and then can further shorten the route of charging, with the reduction generate heat of charging, promote user experience.

For example, as shown in fig. 1, the power interface 10 may include a second sub power interface 102 disposed 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 a power outlet, the sub board 32 may charge the battery 2 through the second flexible circuit board 34, and the battery 2 may discharge the main board 31 through the first flexible circuit board 33. Therefore, the distance between the second side 12 and the sub-board 32 is short, so that the distance between the second sub-power interface 102 and the sub-board 32 can be shortened, the charging path can be further shortened, the charging heating is reduced, and the user experience is improved.

For example, in the example shown in fig. 1, the power interface 10 may include a third sub power interface 103 provided on the third side 13, the third sub power interface 103 falls within a front projection area (e.g., area a shown in fig. 1) of the main board 31 on the third side 13, and the third sub power interface 103 is electrically connected to the main board 31 to charge the battery 2 through the first flexible circuit board 33. That is, when the third sub power interface 103 is connected to a power outlet, the main board 31 may charge the battery 2 through the first flexible circuit board 33, and the battery 2 may discharge the sub board 32 through the second flexible circuit board 34. From this, because the distance of third sub power source 103 and mainboard 31 is nearer to can further shorten the route of charging, with reduce to charge and generate heat, promote user experience. Moreover, in the embodiment, if the distance L1 between the battery protection board 21 and the third side 13 is smaller 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, so as to shorten the length of transferring the electric quantity from the third sub power interface 103 to the first flexible circuit board 33, thereby further shortening the charging path, reducing the heat generated during charging, and improving the user experience.

For example, as shown in fig. 1, the power interface 10 may include a fourth sub power interface 104 disposed on the third side 13, the fourth sub power interface 104 falls within an orthographic projection area (e.g., area B shown in fig. 1) of the sub board 32 on the fourth side 14, and the fourth sub power interface 104 is electrically connected to the sub board 32 to charge the battery 2 through the second flexible circuit board 34. That is, when the fourth sub power interface 104 is connected to the power outlet, the sub board 32 may charge the battery 2 through the second flexible circuit board 34, and the battery 2 may discharge the main board 31 through the first flexible circuit board 33. Therefore, the distance between the fourth sub power source interface 104 and the auxiliary plate 32 is short, so that the charging path can be further shortened, the charging heating is reduced, and the user experience is improved.
