Description

A terminal

Technical field

The present invention relates to the field of electronic communication technology, in particular to a terminal.

Background technique

As we all know, the battery is the core component of mobile phones and other terminals. In order to enable the mobile phone to be able to stand by for a long time, the power storage of the mobile phone becomes the key. Because the higher the battery capacity, the more likely it is to cause safety problems such as battery instability or even explosion, so the capacity of a single battery cannot be large. In order to increase the power storage capacity, some mobile phone manufacturers will adopt a built-in dual-cell structure, that is, multiple cells are connected in parallel to form a large-capacity battery.

Please refer to Figure 1, which shows a layout scheme of the current dual-cell structure. The dual-cell 11 is placed side by side, and two PCB boards 12 are laid out on the upper and lower ends of the battery; refer to Figure 2, which shows the current dual-cell structure. Another layout scheme of the core structure, the dual cell 11 is placed in an L shape, and the PCB board 12 is placed close to the L shape; the PCB board 11 of these two layout schemes will be combined with various device modules in the mobile phone (such as camera, The handset, etc.) are arranged in a staggered layout, and the PCB board 11 and the device module will be matched in size, shape and position according to the shape of the mobile phone.

However, the flaw in the first layout scheme is that when the mobile phone's dimensions (such as length and/or width) are reduced, it will appear that the mobile phone's shape cannot cover the original layout of the PCB board. As a result, it is necessary to re-adjust the size, shape and position of the PCB board and various device modules. However, the adjustment of the PCB board will increase the R&D cost and cycle. At the same time, this solution is prone to heat accumulation, which causes the shell to become hot and hold. The hand feels uncomfortable, and eventually the operating frequency or current limit of modules such as CPU, PMU, PA, and Charger IC have to be reduced to alleviate the overheating of the mobile phone, but these measures will reduce the working performance of the mobile phone and the performance experience during use;

The defect of the second layout scheme is that due to the limitation of the space in the mobile phone, the distance between the PCB board and the frame of the mobile phone is relatively short, and the heat generated by the PCB board is easily transferred to the mobile phone shell, and the heat conducted to the shell is Holding by human hands will cause discomfort in the grip, and the accumulation of heat will cause the working performance of the PCB board 12 to decrease, and the performance experience of the user during use will deteriorate.

Summary of the invention

Based on this, the object of the present invention is to provide a terminal to solve the technical problems of thermal accumulation in the existing layout scheme of the multi-cell structure and the need to adjust the PCB board when the size of the housing is changed.

In addition, the terminal according to the above-mentioned embodiment of the present invention may also have the following additional technical features:

Further, the PCB board includes a first PCB board and a second PCB board laminated on the first PCB board.

Further, the length of the second PCB board is less than the length of the first PCB board.

Further, the second PCB board is connected to the first PCB board by welding or connector connection.

Further, the width of the first gap is between 1-75 mm.

Further, the battery core has a long strip shape and is arranged along the length direction of the housing, and the length of the battery core is less than or equal to the length of the PCB board.

Further, the number of the battery cores is two, the PCB board is arranged on the central area of the housing, and the two battery cores are symmetrically arranged on both sides of the PCB board.

Further, the main heat generating modules on the PCB board are arranged at discrete intervals along the length direction of the PCB board.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "and/or" as used herein includes any and all combinations of one or more related listed items.

Please refer to FIG. 3, which shows a terminal in the first embodiment of the present invention, which includes a housing 13, and a PCB board 12 and two electric cores 11 arranged in the housing 13. among them:

The PCB board 12 is elongated, the PCB board 12 is arranged on the central area of the housing 13 and is arranged along the length of the housing 13, and the two electric cores 11 are arranged along the housing 13 The width direction of the body 13 is symmetrically arranged on both sides of the PCB board 12. After arranging the PCB board 12 and the battery core 11 in the cavity of the housing 13, a first gap 14 is formed at both ends in the length direction, that is, the PCB board 12 and the battery core 11 is located between the two first gaps 14.

In addition, the battery core 11 is also elongated, and is arranged along the length direction of the housing 13. The length of the battery core 11 is less than or equal to the length of the PCB board 12, preferably the two lengths are equal , So that the end of the battery core 11 does not extend into the first gap 14.

Wherein, the width of the PCB board 12 is between 9.0 mm and 32.0 mm, and the width of the battery core 11 is adaptively adjusted according to the width of the PCB board 12. The width of the first gap 14 may be any value between 1-75 mm, preferably 32 mm. At the same time, the width of the two first gaps 14 may be equal or unequal, preferably two first gaps. The width of a gap 14 is equal. Various device modules of the terminal are all arranged in the first gap 14. The device modules include, but are not limited to, cameras, earpieces, flashes, speakers, motors, USB connectors, etc.

In this embodiment, the terminal further includes three rear cameras 15. Since the first gap 14 does not affect the layout integrity of the PCB board 12, the three rear cameras 15 are arranged in an inverted fret pattern. In the first gap 14 at the front end of the housing 13, and the rear camera is preferably arranged in the central area of the first gap 14. In other embodiments, the three rear cameras 15 may also be arranged in a genuine font. At the same time, the rear cameras 15 may also be arranged in the first gap 14 at the rear end of the housing 13.

It should be noted that the genuine font or the inverted font refers to a formation in which three rear cameras 15 are arranged from the perspective of the front or back of the housing 13. At the same time, no matter whether the rear cameras 15 are arranged in a genuine font or in an inverted font, there will always be a connection line between the two rear cameras 15 that is flush with the width direction of the housing 13.

Specifically, as a connection manner, each rear camera 15 may be connected to the PCB board 12 by using a separate FPC board (flexible circuit board). As another alternative connection method, the two rear cameras 15 whose connections are flush with the width of the housing (on the same horizontal line) can also be placed on the same small circuit board in the form of a common substrate. Then, the circuit board is connected to the PCB board 12 through an FPC board, and another rear camera 15 can be connected to the PCB board 12 by an FPC board alone.

In this embodiment, the terminal further includes a flash 16, the flash 16 is installed in the first gap 14 where the rear camera 15 is located, and the flash 16 and the three rear cameras 15 is arranged in a rectangle, and the flashlight 16 and the three rear cameras 15 are located at the midpoint of the four sides of the rectangle.

Further, in order to avoid excessive heat generation, the main heating modules on the PCB board 12 are arranged at discrete intervals along the length of the PCB board 12, which effectively avoids the superposition of heat when the heat sources are concurrent and causes the CPU to be destroyed in a short time. Overheating frequency limit, charging current limit, PA/Wifi device overheating efficiency reduction and other issues.

Specifically, the main heating modules include, but are not limited to, a baseband module 121 and a radio frequency module 122. The baseband module 121 is also called a baseband AP (application processor) module, such as a CPU and a GPU module. The baseband module 121 and the radio frequency module 122 are the most serious heat-generating modules among the PCB board 12.

At the same time, a second gap 17 is provided between the battery core 11, the PCB board 12 and the frame of the housing 13, so as to facilitate the heat dissipation of the terminal in the width direction and prevent heat from being easily transferred to the housing 13. . Preferably, the second gap 17 is smaller than the first gap 14. The second gap 17 can be any value between 0-8 mm, preferably 0.8 mm, to ensure the PCB board 12, the battery core 11 and the shell There is a heat dissipation gap between the bodies 13 in the width direction.

It should be pointed out that in the embodiment, the PCB board 12 is arranged in the central area of the housing 13, and the two batteries 11 are symmetrically arranged on both sides of the PCB board 12. However, the present invention is not limited to this. In other embodiments Among them, the PCB board 12 can also be arranged on any area in the middle of the housing 13 according to the layout requirements, that is, the PCB board 12 can be shifted left and right in the position shown in FIG. 1, and in other embodiments, it can also be arranged more There are many batteries 11, and the multiple batteries 11 may be symmetrically or asymmetrically arranged on both sides of the PCB board 12 along the width direction of the housing 13.

In summary, the terminal in this embodiment is arranged in a strip shape by the PCB board 12 and arranged in the middle of the housing 13 along the length direction of the housing 13, and the two ends of the PCB board 12 are connected to the housing 13. A first gap 14 is formed between the frame of the end, and then a plurality of cells 11 are arranged on both sides of the PCB board 12 along the width direction of the housing 13; when the length of the terminal needs to be adjusted, only the first gap 14 needs to be adjusted The width, and adjusting the size, position, and shape of the device module arranged in the first gap 14 can adapt to the change in the length of the terminal without adjusting the PCB board 12; when the width of the terminal needs to be adjusted, only Adjusting the size, shape, and position of the cells 11 on both sides of the PCB board 12 can adapt to the change in the width of the terminal without adjusting the PCB board 12, which saves the redesign and trial production required to adjust the PCB board. The investment in manpower, material resources and time for commissioning, after-sales spare parts, and maintenance training reduces R&D costs and R&D cycles. At the same time, as the heat on the PCB board 12 is diffused to the terminal frame, it will be greatly weakened due to the relatively large transmission distance and the need to pass through the cold zone of the battery core 11. It is not easy to generate heat accumulation, so that users can obtain good Grip feel. In addition, through the above reasonable layout, a first gap 14 is reserved at one end of the cavity of the housing 13 in the longitudinal direction, and three rear cameras 15 are installed in the first gap 14, and arranged in a fret , The appearance of the layout of the rear camera 15 is improved, and the rear camera 15 can be kept away from the frame of the housing 13 so as not to be easily broken. At the same time, there is no need to slot the PCB board 12 to avoid these rear cameras 15.

The PCB board 12 includes a first PCB board 123 and a second PCB board 124 stacked on the first PCB board 123. The first PCB board 123 is all elongated, the length of the second PCB board 124 is less than the length of the first PCB board 123, and the second PCB board 124 is arranged near the first gap 14 at the front end. Location.

In a specific implementation, the second PCB board 124 is connected to the first PCB board 123 by welding or a connector connection, preferably a connector connection.

It should be pointed out that in this embodiment, a small PCB board 122 is superimposed on the elongated first PCB board 123, so that the components originally laid out on the same PCB board 12 can now be arranged separately on the two stacked one above the other. On the

PCB boards

121 and 122, the overall length of the PCB board 12 is shortened.

In practical applications, when the slender PCB board does not want to be too long; or too many components cause the PCB board to be too long, which affects the size of the first gap 14 at both ends, you can consider the A small PCB board is superimposed on the PCB board, and then they are connected by welding or connectors to achieve the purpose of reducing the length of the PCB board.

In addition, in this embodiment, the three rear cameras 15 of the terminal are arranged in the first gap 14 at the front end in a genuine font, specifically in the central area of the first gap 14. At the same time, The flash 16 and the three rear cameras 15 are arranged in a chevron shape.
