Description

Technical Field

[0002] Existing electronic products are becoming increasingly thinner. For example, tablets are becoming increasingly thinner, with mainstream flagship products having thicknesses down to 5mm. The ultra-thin appearance of these products is very popular among consumers. However, the display quality and refresh rate of electronic product screens are also constantly improving, and the power consumption of the entire device is increasing. Therefore, increasing the battery capacity to ensure a basic endurance experience has become another demand of users.

[0003] At present, the battery life is improved by increasing the battery energy density and increasing the battery capacity, but this method cannot meet the battery life requirements of the whole machine. If the battery life is achieved by thickening the battery and increasing the capacity, it will conflict with the ultra-thin evolution trend of the whole machine. Therefore, how to meet the ultra-thin development and take into account the battery life experience has become the focus of research. Utility Model Content

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0041] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical problems to be solved by the embodiments of the present application are first described.

[0042] refer to Figure 1 , Figure 1 A schematic diagram of the internal stacking structure of an electronic device in some embodiments is shown.

[0043] In each figure herein, the x-axis direction represents the length direction of the electronic device 10, and the y-axis direction represents the width direction of the electronic device 10. The x-axis direction and the y-axis direction are perpendicular.

[0044] like Figure 1 As shown, the electronic device 10 includes a housing 11, and a mainboard 12, two batteries 16, and a screen driver board are arranged in sequence along the y-axis direction inside the housing 11. The mainboard 12 is arranged on the top long side of the housing 11 (such as Figure 1 The main board 12 is provided with a main chip 13 for controlling the whole machine. The screen driving board 14 is close to the bottom long side of the housing 11 (as shown in FIG. Figure 1The screen driver board is provided with a driving chip 15, and the edge of the screen driver board is connected to the screen through a line along the x-axis direction for controlling the display screen. Two batteries 16 are arranged side by side between the main board 12 and the screen driver board 14.

[0045] Usually, the mainboard 12 is roughly rectangular in design, and its width (width on the y-axis) is usually determined by the layout of the main chip 13 and the width of the wiring, and the non-main chip area and the area where the main chip 13 is located maintain the same width in the y-axis direction. The screen driver board 14 also adopts a rectangular structure, and its width (width on the y-axis) is determined by the width of the driver chip 15 and its wiring width, and the non-driver chip area maintains the same width as the area where the driver chip 15 is located. The design of this structure is more convenient in manufacturing. However, in terms of the overall layout, there are limitations on the increase in battery volume, which is not conducive to the increase in battery capacity.

[0046] Based on the drawbacks of the electronic device structure layout in the above-mentioned embodiment, combined with user needs, considering that in actual product design, based on the improvement of device miniaturization and high-density layout capabilities, the layout of the mainboard 12 and the screen driver board 14 can have area redundancy, thus proposing an electronic device of the embodiment of the present application. The electronic device utilizes the area redundancy of the mainboard 12 and the screen driver board 14 to divide the mainboard 12 and the screen driver board 14 into different areas, and the main chip 13 and the driver chip 15 are staggered in the y direction, and the area without the chip is reduced or split, thereby providing a larger space for the battery in the y-axis direction. Thereby, without increasing the thickness of the whole machine, the battery layout area can be increased, and the battery capacity can be increased to improve the product endurance experience.

[0047] The electronic device according to the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0048] The storage assembly of the embodiment of the present application can be applied to electronic devices, wherein the electronic devices can be, but are not limited to, a tablet personal computer, a straight-screen mobile phone, a folding screen mobile phone, a tablet computer, an e-book reader, a laptop computer, a personal digital assistant (PDA), a notebook, and other electronic devices. In the following embodiments, the electronic device is a tablet computer as an example for explanation.

[0049] refer to Figure 2 , Figure 2 FIG. 1 is a schematic diagram showing the internal layout structure of a tablet of the first embodiment of the present application. Figure 2As shown, the tablet 100 includes a housing 110, a mainboard 120 (first circuit board), a screen driving board 130 (second circuit board), a first battery 140 and a second battery 150. A receiving space 111 is formed inside the housing 110, and the receiving space 111 has a certain length in the x-axis direction and a certain width in the y-axis direction.

[0050] like Figure 2 As shown, the main board 120 is located at the top of the storage space 111. The main board 120 includes a first sub-circuit board 121 and a second sub-circuit board 122 connected to the first sub-circuit board 121. The first sub-circuit board 121 is located on the right side of the storage space (the right side of the middle line of the shell), and the second sub-circuit board 122 is located on the left side of the storage space 111. The main chip 123 (first chip) is set on the first sub-circuit board 121, so that the redundant area on the second circuit board 122 can be removed, which can provide space for the layout of the battery. Figure 3 The structure of the main board is described in detail.

[0051] refer to Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the structure of the mainboard 120 in the first embodiment of the present application. Figure 3 As shown, the width of the second sub-circuit board 122 of the main board 120 in the y-axis direction is smaller than that of the first sub-circuit board 121, and the width difference between the two in the y-axis direction is d1, and a step shape is formed. When the battery is laid out, the layout of the battery in the y-axis direction can increase the height of d1, which is conducive to increasing the battery capacity.

[0052] Continue to refer Figure 2 The screen driving board 130 is located at the bottom of the accommodating space 111, and includes a third sub-circuit board 131 and a fourth sub-circuit board 132. The third sub-circuit board 131 is connected to the fourth sub-circuit board 132, and is located on the right side of the accommodating space 111 (on the right side of the middle line of the shell), and is opposite to the first sub-circuit board 121 up and down. The fourth sub-circuit board 132 is located on the left side of the accommodating space 111 (on the left side of the middle line of the shell), and is opposite to the second sub-circuit board 122 up and down. The driving chip 133 (second chip) is arranged on the fourth sub-circuit board 132, so that the redundant area of ​​the third sub-circuit board 131 can be removed. The following is combined with Figure 4 The structure of the screen driving board 130 will be described in detail.

[0053] refer to Figure 4 , Figure 4 FIG. 1 shows a schematic diagram of the structure of the screen driving board 130 in the first embodiment of the present application. Figure 4As shown, the width of the third sub-circuit board 131 in the y-axis direction is smaller than that of the fourth sub-circuit board 132, and the width difference between the third sub-circuit board 131 and the fourth sub-circuit board 132 in the y-axis direction is d2, forming a step shape. Figure 2 The first battery shown in the figure can increase the height of d2 in the y-axis direction, which is beneficial to improving the battery capacity.

[0054] like Figures 2 to 4 As shown, the first battery 140 and the second battery 150 are respectively located on the left and right sides of the center line of the housing 110. The first battery 140 is arranged between the third sub-circuit board 131 and the first sub-circuit board 121. The first battery 140 overlaps with the fourth sub-circuit board 132 in the x-axis direction, that is, the first battery 140 is larger in the y-axis direction than the original structure (see Figure 1 The second battery 150 is located between the second sub-circuit board 122 and the fourth sub-circuit board 132, and the top of the second battery 150 overlaps with the first sub-circuit board 121 in the x-axis direction, that is, the second battery 150 is larger in the y-axis direction than the original structure (see Figure 1 The battery structure shown in the figure) extends upward by approximately a height of d1, thereby forming an upper and lower staggered arrangement.

[0055] It should be noted that the heights d1 and d2 may be equal or different in size, and in the actual manufacturing process, they may be reasonably set according to the respective redundancy of the main board 120 and the screen driver board 130. In addition, the embodiment of the present application is described by taking the main board 120 as the first circuit board, the main chip 123 as the first chip, the screen driver board 130 as the second circuit board, and the screen driver chip 133 as the second chip as an example. In some possible embodiments, other circuit boards may also be used.

[0056] The internal structure layout of the tablet 100 of the embodiment of the present application adopts a staggered layout of the main chip 123 of the mainboard 120 and the driver chip 133 of the screen driver board 130, and the non-chip area can be used to remove redundancy, so that the two batteries can expand the space in the y direction, solving the bottleneck of the original layout method inside the electronic device that cannot be stacked in the y direction. Combined with the upper and lower staggered packaging of the batteries, a stepped stacking layout is realized, so that the battery layout area ratio can be increased without changing the thickness of the tablet 100, and the battery capacity is greatly increased. After experimental verification, the battery capacity improvement rate can reach about 8%, which effectively improves the product life and enhances the user's life experience. In addition, for the two batteries, the size can still remain the same, and there is no need to consider the problem of special-shaped design of batteries of different sizes in the preparation process, which is conducive to reducing the difficulty of process manufacturing.

[0057] The above embodiment is described by taking the example of removing redundancy on the side where no chip is set for both the mainboard 120 and the screen driver board 130. In some embodiments, the redundancy of the chip-free area of ​​the mainboard 120 may be removed separately, or the redundancy of the chip-free area of ​​the screen driver board may be removed separately. This will be further described in the following embodiments.

[0058] refer to Figure 5 , Figure 5 A schematic diagram of the internal structure of a tablet according to a second embodiment of the present application is shown.

The first battery is arranged between the first sub-circuit board and the second circuit board, the second battery is arranged between the second sub-circuit board and the second circuit board, and the second battery overlaps with the first sub-circuit board in the second direction.

[0059] Specifically, if Figure 5 As shown, the tablet 100 includes a housing 110, a mainboard 120 (first circuit board), a screen driving board 130 (second circuit board), a first battery 140 and a second battery 150. The mainboard 120 is arranged in the same manner as Figure 2 and Figure 3 The same as explained in the embodiment, please refer to Figure 2 and Figure 3 The difference is that the screen driver board 130 does not remove redundancy, that is, the size of the screen driver board 130 is not adjusted. At this time, there is no restriction on the location of the driver chip 133. For example, Figure 3 As shown, the driving chip 133 can be arranged on the left side of the screen driving board 130, or on the right side of the screen driving board 130. In addition, the sizes of the first battery 140 and the second battery 150 are different. The first battery 140 maintains the original size, while the size of the second battery 150 is increased in the y-axis direction (as shown in FIG. Figure 6 As shown, the length extending upward in the y-axis direction) is increased, thereby increasing the capacity of a single battery and improving the overall battery capacity. The size of the screen driving board 130 does not need to be adjusted, which can reduce the process adjustment time.

[0060] In other embodiments, Figure 3 The main chip 123 of the main board 120 can also be set on the left side, which is not limited in the present application.

The screen driver board 130 is arranged in the same manner as Figure 2 and Figure 4 The same as explained in the embodiment, please refer to Figure 2 and Figure 4 The difference is that the mainboard 120 does not remove redundancy, that is, the size of the mainboard 120 is not adjusted. At this time, there is no restriction on the location of the main chip 123. For example, Figure 6 As shown, the main chip 123 can be arranged on the left side of the main board 120, or on the right side of the main board 120. In addition, the first battery 140 and the second battery 150 have different sizes. The second battery 150 maintains the original size, while the size of the first battery 140 is increased in the y-axis direction (as shown in FIG. Figure 6 As shown, the length extending downward in the y-axis direction) is increased, thereby increasing the capacity of a single battery and improving the overall battery capacity, and the size of the mainboard 120 does not need to be adjusted, which can reduce the adjustment time in the process.

[0063] The fourth embodiment of the present application is described below.

[0064] refer to Figure 7 , Figure 7The schematic diagram of the structure inside the tablet of the fourth embodiment of the present application is shown.

The first circuit board includes a first sub-circuit board and a second sub-circuit board, a first chip is arranged on the first circuit board, and the first sub-circuit board and the second sub-circuit board are arranged at intervals along the second direction. The second circuit board includes a third sub-circuit board and a fourth sub-circuit board, the third sub-circuit board and the fourth sub-circuit board are stepped, the width of the third sub-circuit board in the first direction is smaller than that of the fourth sub-circuit board, and the second chip is arranged on the fourth sub-circuit board; the first sub-circuit board is directly opposite to the third sub-circuit board, and the second sub-circuit board is opposite to the fourth sub-circuit board.

The screen driver board 130 is arranged in the same manner as Figure 2 and Figure 4 The same as explained in the embodiment, please refer to Figure 2 and Figure 4 The screen driving board 130 explained above is different in that the first sub-circuit board 121 and the second sub-circuit board of the main board 120 are no longer connected, but a gap 124 is formed in the x-axis direction, thereby providing a larger space for the battery to extend in the y-axis direction. Figure 7 As shown, the top of the second battery 150 can extend upward to a greater length, and the top of the battery is almost close to the top of the mainboard 120. Compared with the first embodiment, this structure can further increase the battery layout area ratio, and the battery capacity is increased to a greater extent.

[0066] refer to Figure 8 , Figure 8 The schematic diagram of the structure inside the tablet of the fifth embodiment of the present application is shown.

Compared with the fourth embodiment, this structure can reduce the adjustment steps of the screen driving board 130 process in the manufacturing process.

[0068] Since the above embodiments involve the adjustment of battery size, a battery heterogeneous packaging design suitable for the above type of battery should be selected during battery packaging.

One end of the connecting plate 163 is connected to the first sub-plate 161, and the other end is connected to the second sub-plate 162, forming a Z-shaped structure.

The bottom end of the second sub-board 162 is connected to the second battery 150, and the top end is connected to the second sub-circuit board 122. This structure is arranged according to the battery staggered structure, and the battery staggered packaging can be realized.

[0072] It should be noted that in the above embodiment, two batteries are used as an example for the description. In some embodiments, when three or more batteries are provided, the main board and the screen driver board may also be divided into multiple areas. Taking the main board 120 as an example, the redundancy is removed on both sides of the main chip 123 to achieve the setting of three areas to adapt to the design of different numbers of batteries. This embodiment of the application is not limited to this.

[0075] In other embodiments, the reinforcing plate may be a steel material, which is strong and is conducive to better protection of the protection plate and improving the connection strength of the protection plate.

[0076] In summary, the electronic device according to the embodiment of the present application utilizes the stacking space advantage of the ladder structure and combines it with the special-shaped packaging solution of large and small battery cells to increase the battery capacity without changing the thickness of the electronic device.

[0077] It should be noted that the mutual parallelism in the present application is not absolute parallelism, and the approximate parallelism caused by processing errors and assembly errors (for example, the angle between two structural features is 0.1°) is also within the scope of mutual parallelism in the present application.
