[0025] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0026] As used herein, "electronic device" refers to a device that can receive and / or send communication signals, including but not limited to a device that is connected via any one or more of the following connection methods:

[0027] (1) Connection via wired lines, such as Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, and direct cable connection;

[0028] (2) Via wireless interfaces, such as cellular networks, wireless local area networks (WLAN), digital television networks such as DVB-H networks, satellite networks, and AM-FM broadcast transmitters.

[0029] An electronic device configured to communicate via a wireless interface may be referred to as a "mobile terminal". Examples of mobile terminals include, but are not limited to, the following electronic devices:

[0030] (1) Satellite phone or cellular phone;

[0031] (2) Personal Communications System (PCS) terminals that can combine cellular radio telephones with data processing, fax, and data communications capabilities;

[0032] (3) Radiotelephone, pager, Internet / Intranet access, Web browser, notepad, calendar, Personal Digital Assistant (PDA) equipped with a Global Positioning System (GPS) receiver;

[0033] (4) conventional laptop and / or handheld receivers;

[0034] (5) Conventional laptop and / or palmtop radiotelephone transceivers, etc.

[0035] In order to improve the charging efficiency, the battery assembly in the electronic device is usually provided with two BTB connectors. Both BTB connectors are electrically connected to the mainboard of the electronic device, and extend into the housing of the battery assembly through a flexible printed circuit (FPC) to be electrically connected to the protection board of the battery assembly. In order to meet the assembly and connection requirements of the entire electronic device, the FPC connected to at least one BTB connector is usually long, and at least part of the FPC needs to be fixed to the housing of the battery assembly to avoid the battery assembly swinging back and forth when the battery assembly is assembled to the electronic device, resulting in the battery assembly not being able to be installed or causing the BTB connector to be damaged. In traditional battery assemblies, U-shaped adhesive tape and adhesive provided between the FPC and the housing are usually used to fix the FPC to the housing. This fixing method will increase the number of auxiliary materials and assembly processes, making the board-to-board connector setting process complicated, reducing production efficiency, and increasing production costs. At the same time, multiple adhesive tapes will also increase the length of the battery assembly, which is not conducive to the assembly of the battery assembly and the miniaturization design of electronic equipment.

[0036] In order to solve the above problems, the present application provides a battery assembly and a preparation method thereof and an electronic device.

[0037] See also Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 is a schematic diagram of the structure of the electronic device 10 in some embodiments, Figure 2 is a schematic diagram of the structure of some components of the battery assembly 20 in some embodiments, Figure 3 Schematic diagram of explosion of some components of battery assembly 20 in some embodiments. The electronic device 10 provided in the present application includes but is not limited to a smart phone, a tablet computer, an e-reader, etc. The electronic device 10 may include a middle frame 11, a back plate 12 and a display panel. The back plate 12 and the display panel are arranged on two opposite sides of the middle frame 11. The middle frame 11, the back plate 12 and the display panel are surrounded to form an accommodation space. The electronic device 10 also includes a motherboard 13 and a battery assembly 20 accommodated in the accommodation space. The battery assembly 20 is used to power various components in the electronic device 10.

[0038] In some embodiments, the battery assembly 20 includes a housing 21, a battery cell contained in the housing 21, and a protection circuit board 23 electrically connected to the battery cell. The battery assembly 20 is further provided with a flexible circuit board 24 and a connection element 25. The flexible circuit board 24 is partially located in the housing 21 and partially led out of the housing 21. The part of the flexible circuit board 24 located in the housing 21 is electrically connected to the protection circuit board 23, and the part of the flexible circuit board 24 located outside the housing 21 is electrically connected to the connection element 25. The connection element 25 is used to be electrically connected to the main board 13, thereby realizing the electrical connection between the main board 13 and the protection circuit board 23.

[0039] Among them, the mainboard 13 can be a printed circuit board (PCB), and the mainboard 13 can be provided with components such as a central processing unit (CPU), a graphics processing unit (GPU), a power management chip, and a storage controller. The flexible circuit board 24 can be an FPC, the connecting element 25 can be a BTB connector, and the protection circuit board 23 can be an FPC, which is mainly used to protect the battery cell to prevent overcharging, overdischarging, short circuit, etc. When the protection circuit board 23 is electrically connected to the mainboard 13 through the flexible circuit board 24 and the connecting element 25, the connecting element 25 can transmit the power supply information of the battery (such as battery power, voltage, etc.) to the power management chip of the mainboard 13, and can also transmit the control signal of the mainboard 13 (such as charging control signal, etc.) to the protection circuit board 23, so that the electronic device 10 can accurately obtain the battery status information and effectively control the charging and discharging process of the battery.

[0040] Further, in some embodiments, a glue dispensing groove 211 is provided on the outer surface of the housing 21. When the battery cell and the protection circuit board 23 are accommodated in the housing 21, the glue dispensing groove 211 is provided on the outer surface of the housing 21 facing away from the battery cell and the protection circuit board 23. The flexible circuit board 24 partially extends from the housing 21 to the outside of the housing 21 and covers the glue dispensing groove 211. The connecting element 25 is provided at one end of the flexible circuit board 24 away from the housing 21. The adhesive structure 22 is provided in the glue dispensing groove 211 and adheres the flexible circuit board 24 and the housing 21. It can be understood that the adhesive structure 22 includes but is not limited to any suitable material such as glue that can adhere the part of the flexible circuit board 24 covering the glue dispensing groove 211 to the housing 21. By adhering part of the flexible circuit board 24 to the housing 21 through the adhesive structure 22, the flexible circuit board 24 can be limited relative to the housing 21, so that during the process of assembling the battery assembly 20 to the electronic device 10, the flexible circuit board 24 is not easy to swing, resulting in the battery assembly 20 not being able to be installed, or causing the connecting element 25 to be damaged.

[0041] At the same time, the glue dispensing groove 211 is provided on the housing 21, and the method of fixing the flexible circuit board 24 by glue in the glue dispensing groove 211 requires less auxiliary materials than the traditional method of fixing with multiple adhesive tapes, and the preparation process is simple and fast, which is conducive to reducing the difficulty and cost of setting the connecting element 25 and the flexible circuit board 24. Furthermore, the glue dispensing groove 211 is recessed on the housing 21, and the adhesive structure 22 is located in the glue dispensing groove 211. The setting of the glue dispensing groove 211 and the adhesive structure 22 will not increase the volume of the battery assembly 20, which is conducive to the assembly of the battery assembly 20 on the electronic device 10 and the miniaturization design of the electronic device 10.

[0042] In some embodiments, the material of the housing 21 includes but is not limited to plastic, etc. The housing 21 is made by injection molding, and the glue spot groove 211 is formed in the injection molding process of the housing 21. For example, by designing the injection mold of the housing 21, a protruding structure is provided at the position of the injection mold corresponding to the glue spot groove 211, so that the housing 21 forms the glue spot groove 211 after injection molding. It can be seen that the provision of the glue spot groove 211 does not increase the preparation process of the housing 21, which is conducive to simplifying the preparation process of the battery assembly 20.

[0043] In some embodiments, the depth of the glue dispensing groove 211, that is, the dimension of the glue dispensing groove 211 in a direction perpendicular to the outer surface of the housing 21 where the glue dispensing groove 211 is provided, is Figure 3 The dimension A shown is greater than or equal to 0.2 mm and less than or equal to 0.4 mm, for example, 0.25 mm. In this way, the dispensing groove 211 has enough depth to accommodate the adhesive structure 22, which is conducive to improving the fixing effect of the adhesive structure 22 on the flexible circuit board 24, and can also reduce the risk of adhesive overflow of the adhesive structure 22.

[0044] Combination Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the flexible circuit board 24 includes a first lead-out end 241, a first connection end 242, and a first body 243. The first lead-out end 241 and the first connection end 242 can be regarded as two ends of the part of the flexible circuit board 24 located outside the housing 21, and the first body 243 can be regarded as the body of the part of the flexible circuit board 24 located outside the housing 21. The first body 243 is connected to the first lead-out end 241 and the first connection end 242. The first lead-out end 241 is led out from the housing 21, and the first connection end 242 is connected to the connecting element 25. That is, the first lead-out end 241 can be an end of the part of the flexible circuit board 24 located outside the housing 21 close to the housing 21, and the first connection end 242 can be an end of the part of the flexible circuit board 24 located outside the housing 21 away from the housing 21. The part of the first body 243 connected to the first lead-out end 241 covers the glue dispensing groove 211, that is, the glue dispensing groove 211 is arranged near the first lead-out end 241, and the orthographic projection of the first connection end 242 on the housing 21 is located outside the glue dispensing groove 211, that is, no glue is dispensed at the first connection end 242. Thus, the part of the flexible circuit board 24 close to the connecting element 25 can reserve enough margin for movement, so that when the connecting element 25 is buckled with the components of the electronic device 10, the flexible circuit board 24 can meet the margin for pulling, which facilitates the smooth buckling of the connecting element 25.

[0045] In some embodiments, in the direction from the first lead-out end 241 to the first connection end 242, the size of the dispensing groove 211 (i.e. Figure 4 The length of the first body 243 and the first connecting end 242 (i.e. Figure 2 The ratio of the dimension C) shown is greater than or equal to 1 / 3 and less than or equal to 2 / 3, for example, it can be 2 / 3. Therefore, the glue dispensing groove 211 has a sufficient length to accommodate the adhesive structure 22, so that there is a sufficient adhesion dimension between the adhesive structure 22 and the flexible circuit board 24, which improves the fixing effect of the flexible circuit board 24 on the housing 21, and is also conducive to ensuring that the end of the flexible circuit board 24 connected to the connecting element 25 has sufficient margin of activity, meets the buckling requirements of the connecting element 25, and reduces the risk of damage to the connecting element 25 and the flexible circuit board 24.

[0046] Please see again Figure 2 and Figure 3In some embodiments, the battery assembly 20 further includes a flexible circuit structure 26 and a connection structure 27. The flexible circuit structure 26 is led out from the housing 21, and the connection structure 27 is connected to one end of the flexible circuit structure 26 away from the housing 21. The flexible circuit structure 26 may also be an FPC, and the connection structure 27 may also be a BTB connector. The portion of the flexible circuit structure 26 located in the housing 21 is electrically connected to the protection circuit board 23, and the connection structure 27 is electrically connected to the main board 13 of the electronic device 10. In other words, the battery assembly 20 is provided with a double BTB connector. In some embodiments, the housing 21 may be a rectangular parallelepiped structure, and the flexible circuit board 24 and the flexible circuit structure 26 may be led out from the housing 21 toward one side of the main board 13, which is conducive to adapting to the layout of the battery assembly 20 and the main board 13 in the electronic device 10.

[0047] In some embodiments, the length of the portion of the flexible circuit structure 26 outside the housing 21 is less than the length of the portion of the flexible circuit board 24 outside the housing 21, and the battery assembly 20 does not set glue and glue grooves to fix the portion of the flexible circuit structure 26 outside the housing 21. The length of the portion of the flexible circuit structure 26 outside the housing 21 is set to be less than the length of the portion of the flexible circuit board 24 outside the housing 21, so that the flexible circuit board 24 has enough length so that the connecting element 25 can adapt to the position layout of the connecting structure 27. At the same time, only one glue dispensing groove 211 and one adhesive structure 22 need to be set to fix the longer flexible circuit board 24, and there is no need to dispensing glue to fix the flexible circuit structure 26. The shorter flexible circuit structure 26 is not easy to swing during assembly and affect assembly. Therefore, by reasonably setting the length relationship and layout of the FPC of the double BTB connector, the structural reliability of the battery assembly 20 is effectively improved, the preparation process is simplified, and the preparation difficulty and preparation cost are reduced.

[0048] In some embodiments, the flexible circuit structure 26 includes a second lead-out end 261, a second connection end 262, and a second body 263, the second body 263 is connected to the second lead-out end 261 and the second connection end 262, the second lead-out end 261 is led out from the housing 21, and the second connection end 262 is connected to the connection structure 27. The second lead-out end 261 is an end of the flexible circuit structure 26 located outside the housing 21 close to the housing 21, and the second connection end 262 is an end of the flexible circuit structure 26 located outside the housing 21 away from the housing 21. The first body 243 extends in the direction from the first lead-out end 241 to the first connection end 242, and the second body 263 has a corner in the direction from the second lead-out end 261 to the second connection end 262. As a result, the flexible circuit board 24 has a sufficient extension length to meet the layout requirements of the connecting element 25 and the connecting structure 27, and the second body 263 of the flexible circuit structure 26 can shorten the swing length of the flexible circuit structure 26 by bending, without the need for dispensing and not easily affecting the assembly of the battery assembly 20 due to swinging.

[0049] In some embodiments, the orthographic projections of the parts of the flexible circuit board 24 and the flexible circuit structure 26 outside the housing 21 on the housing 21 are spaced apart, and the flexible circuit board 24, the flexible circuit structure 26, the connecting element 25 and the connecting structure 27 are not easy to interfere with each other. In the direction from the first lead-out end 241 to the first connecting end 242, the first lead-out end 241, the first connecting end 242, the second lead-out end 261 and the second connecting end 262 are arranged in sequence, and the orthographic projection of the connecting structure 27 on the flexible circuit structure 26 falls on the flexible circuit structure 26. In this way, the swing length of the flexible circuit structure 26 can be effectively shortened, while adapting to the layout of the connecting structure 27 and the connecting element 25, and improving the structural stability and reliability of the battery assembly 20.

[0050] In some embodiments, a first slot body 212 and a second slot body 213 are provided on the same outer surface of the housing 21, and the housing 21 is further provided with a first outlet 214 connected to the first slot body 212 and a second outlet 215 connected to the second slot body 213. The first slot body 212, the second slot body 213, the first outlet 214 and the second outlet 215 can also be formed in the injection molding process of the housing 21 by designing the injection mold of the housing 21, so as to simplify the preparation process of the housing 21. In the connection direction of the connecting element 25 and the connecting structure 27, the size of the second slot body 213 is larger than the size of the first slot body 212, the first lead-out end 241 is led out from the first outlet 214 and bent inside the first slot body 212, the first body 243 is located outside the first slot body 212, a portion of the second body 263 is located inside the second slot body 213, and a portion of the second slot body 213 is bent out, and the glue dispensing groove 211 is provided on the outer surface of the housing 21 and is located outside the first slot body 212 and the second slot body 213. Thus, the layout between the flexible circuit board 24, the flexible circuit structure 26 and the shell 21 can be reasonably arranged, which is beneficial to improving the structural compactness of the battery assembly 20 and compressing the space occupied by the battery assembly 20. At the same time, it can also better adapt to the position layout of the connecting structure 27 and the connecting element 25, which is beneficial to the connection between the battery assembly 20 and the main board 13. In addition, the longer flexible circuit board 24 is extended to adapt to the spatial layout, and the length of the flexible circuit structure 26 is set to be shorter, and only one glue dispensing groove 211 and an adhesive structure 22 are required. While improving performance reliability, it is beneficial to simplify the preparation process of the battery assembly 20 and reduce the preparation difficulty and preparation cost.

[0051] Combination Figure 2 , Figure 3 and Figure 6 As shown, based on the battery assembly 20 described in any of the above embodiments, the present application also provides a method for preparing the battery assembly 20, including:

[0052] Step S110 , preparing the housing 21 by injection molding, and the outer surface of the housing 21 prepared by the injection molding process is concavely provided with a glue dispensing groove 211 .

[0053] In step S120 , the flexible circuit board 24 is partially located in the housing 21 and partially extends from the housing 21 to the outside of the housing 21 .

[0054] Step S130 , setting the adhesive structure 22 in the adhesive dispensing groove 211 , that is, dispensing glue in the adhesive dispensing groove 211 , and adhering the flexible circuit board 24 to the housing 21 through the adhesive structure 22 .

[0055] It should be noted that the preparation method of the above-mentioned battery assembly 20 may also include arranging battery cells and a protection circuit board 23 in the shell 21, electrically connecting the portion of the flexible circuit board 24 located in the shell 21 to the protection circuit board 23, and fastening the portion of the flexible circuit board 24 located outside the shell 21 to the main board 13 through a connecting element 25.

[0056] In the above preparation method, the housing 21 can be prepared by injection molding using any suitable plastic material. By designing the shape of the injection mold, the housing 21 after injection molding is provided with a glue dispensing groove 211, which can effectively simplify the preparation process of the housing 21 and reduce the preparation difficulty and preparation cost. The method of fixing the flexible circuit board 24 by glue dispensing is also conducive to reducing the auxiliary materials of the battery assembly 20, compressing the volume of the battery assembly 20, and facilitating the assembly of the battery assembly 20 and the miniaturization design of the electronic device 10, compared with the conductive method of fixing with a variety of adhesive tapes.

[0057] refer to Figure 7 , Figure 7 The electronic device 10 is a schematic diagram of the structure of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. Those skilled in the art will understand that Figure 7 The structure of the electronic device 10 shown in the figure does not constitute a limitation on the electronic device 10, and the electronic device 10 may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0058] The radio frequency circuit 501 can be used to send and receive information, or receive and send signals during a call. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Generally, the radio frequency circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the radio frequency circuit 501 can also communicate with the network and other devices through wireless communication.

[0059] The memory 502 can be used to store applications and data. The applications stored in the memory 502 contain executable codes. The applications can form various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0060] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD, Liquid Crystal Display), an organic light-emitting diode (OLED, Organic Light-Emitting Diode), etc. Further, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Figure 7 In the embodiment, the touch-sensitive surface and the display panel are used as two independent components to realize input and output functions, but in some embodiments, the touch-sensitive surface and the display panel can be integrated to realize input and output functions.
