Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of button cell assembly, and in particular to an electronic device and a button cell. Background Art

[0002] Steel shell button batteries are widely used in various fields of microelectronic products, such as but not limited to Bluetooth headsets, hearing aids, wearable devices, etc. For the assembly between button batteries and the whole machine, the following requirements usually need to be met. First, there needs to be a stable and reliable connection between the button battery and the whole machine to avoid the impact of mechanical shocks such as falling during use, to prevent the button battery from being firmly fixed and causing poor contact between the positive and negative terminals; second, the replacement of button batteries needs to have good operability, and when the battery reaches the end of its service life or the battery is damaged and needs to be replaced, the connection with the whole machine can be easily released; third, the internal space of the whole machine should be reasonably used to meet the trend of product miniaturization design.

[0003] A typical way to assemble and connect button batteries to the whole device is to press the button batteries into a dedicated battery holder and fix them by squeezing the springs on the battery holder and limiting the position of the buckle. This is convenient for assembly. However, when used in vibration and falling scenarios, poor contact of the terminals may occur, and there is a lack of force points when removing the button batteries, making removal difficult.

[0004] Another typical method of assembling and connecting button batteries to the whole device is to use adhesives such as back glue and glue point to fix the button batteries to the whole device, which can achieve reliable fixation and occupy less space. However, it is difficult to disassemble, and the disassembly process is easy to damage the battery and other components. Utility Model Content

[0043] The embodiment of the present application provides an assembly implementation scheme for a button battery, which effectively improves the operability of disassembly and assembly of the button battery while meeting the application reliability.

[0044] Steel shell button battery refers to a small cylindrical battery with a stainless steel shell, which is mainly used in micro electronic products such as Bluetooth headsets, hearing aids, wearable devices, etc. Figure 1 , which is a schematic diagram of the overall structure of an ear clip type Bluetooth headset provided in an embodiment of the present application. The headset 100 includes a sound output unit 20 and a clip unit 30, which are connected by a flexible connecting bridge 40 to adapt to individual differences of users. When worn, the sound output unit 20 is aligned with the ear canal in front, and the clip unit 30 is clipped to the back side of the auricle in the back. Among them, the button battery 10 for power supply is built into the clip unit 30.

[0045] by Figure 1 Take the button battery application scenario shown in as an example. During use, the button battery 10 needs to have a stable and reliable connection relationship with the fixed structure (complete machine) such as the shell of the entrainment unit 30. For possible mechanical shocks such as falling, it can ensure that the button battery remains stably and reliably assembled and fixed in the complete machine, while avoiding poor contact between the positive and negative terminals. When the battery reaches the end of its service life or the battery is damaged and needs to be replaced, the connection relationship with the complete machine can be easily released to avoid damage to the battery or complete machine components.

[0046] Based on this, an embodiment of the present application provides a button battery, in which a winding core is arranged in a shell of the button battery, and the shell includes a first shell portion and a second shell portion axially opposite to each other, the first shell portion and the second shell portion are insulated, the first shell portion is electrically connected to the first pole piece of the winding core, and the second shell portion is electrically connected to the second pole piece of the winding core, and the winding core has an axially through-hole; the first shell portion includes a first threaded hole, and the second shell portion includes a second threaded hole, the first threaded hole and the second threaded hole are respectively embedded in the through holes at both ends of the winding core, and the first threaded hole and the second threaded hole are both constructed as electrode connection ends that are compatible with the external threads of the fastener; that is, the first threaded hole and the second threaded hole are used to be electrically connected to the load, and at least one of the first threaded hole and the second threaded hole is also used to be fixedly connected to an external structure through a fastener.

[0047] In this way, the first threaded hole and the second threaded hole at both ends of the button battery are respectively adapted to the corresponding fastener threads to achieve a detachable fastening connection relationship, thereby realizing the assembly and fixation of the button battery, ensuring the reliable fixation of the battery in the whole machine; based on the threaded connection method, it is convenient to realize the disassembly and assembly operation of the button battery, and the possibility of damaging the battery and other devices during the disassembly process can be avoided. In addition, the first threaded hole and the second threaded hole are embedded in the through hole in the middle of the winding core, the battery size is relatively compact, and its assembly connection structure does not occupy additional assembly space of the whole machine, which can take into account both connection reliability and detachability. In addition, based on the fasteners fastened to the corresponding threaded hole sections, the conductors of the corresponding conductive parts can be clamped and fixed respectively. On the basis of reliably fixing the button battery, the first threaded hole and the second threaded hole serve as the positive and negative connection terminals of the button battery, and the electrical connection between the positive and negative electrodes of the battery and the corresponding conductive parts is realized simultaneously, which can effectively avoid mechanical impact affecting the connection reliability of the positive and negative terminals; compared with the structural form of the traditional button battery in which the adapter or conductive part is welded on the surface to establish an electrical connection, the application of the embodiment of the present application can reduce the manufacturing cost.

[0048] In order to better understand the technical solution and technical effect of the present application, without loss of generality, the following will be combined with the accompanying drawings and the configuration of the first threaded hole as the positive electrode connection end and the second threaded hole as the negative electrode connection end to describe a specific embodiment in detail. Figure 2 and Figure 3 ,in, Figure 2 A schematic diagram of a button battery provided in an embodiment of the present application, Figure 3 for Figure 2 AA section view in.

[0049] like Figure 2 and Figure 3As shown, the button battery 10 includes a shell 1 and a winding core 4 arranged on the shell 1, and is electrically connected to an external circuit through a positive electrode mounting member 2 and a negative electrode mounting member 3 that are axially opposite to each other to realize the charging and discharging functions. Here, the positive electrode mounting member 2 and the negative electrode mounting member 3 serve as the first pole electrical connection end and the second pole electrical connection end of the button battery, respectively. Specifically, a first threaded hole 21 is provided on the positive electrode mounting member 2, and a second threaded hole 31 is provided on the negative electrode mounting member 3. Based on the configuration of the corresponding threaded hole segments, the physical connection and fixation of the button battery, as well as the electrical connection of the positive and negative electrodes of the battery are simultaneously realized.

[0050] In this embodiment, the housing 1 includes a negative electrode housing 11, a negative electrode housing cover 12 and a positive electrode housing cover 13, which enclose an internal space for accommodating the winding core 4. Figure 4 and Figure 5 ,in, Figure 4 for Figure 2 The exploded diagram of the button battery assembly shown in the figure. Figure 5 for Figure 3 B view.

[0051] Among them, the negative electrode shell 11 is cylindrical and has an opening at one axial end. The negative electrode shell cover 12 is fixedly connected to the open circumference of the negative electrode shell 11, and the two can be connected by a welding process, such as but not limited to laser welding or ultrasonic welding. The positive electrode shell cover 13 is located on the inner side of the negative electrode shell cover 12, and is fixedly connected to the negative electrode shell cover 12 through a sealing ring 14, and insulation is established between the negative electrode shell cover 12 and the positive electrode shell cover 13, such as but not limited to using a bonding process to achieve reliable fixation between the three. This is not limited to the embodiments of the present application.

[0052] like Figure 5 As shown, the positive electrode case cover 13 is the first shell part of the shell 1, and the bottom wall of the negative electrode case 11 is the second shell part of the shell 1. The two are arranged opposite to each other in the axial direction, and the bottom walls of the positive electrode case cover 13 and the negative electrode case 11 are both provided with through openings opposite to the through holes 43 of the winding core 4. The positive electrode case cover 13 is electrically connected to the positive electrode sheet of the winding core 4 through the positive electrode tab 41, and the side wall of the negative electrode case is electrically connected to the negative electrode sheet of the winding core 4 through the negative electrode tab 42.

[0053] In a specific implementation, during the manufacturing process of the battery roll core 4, a winding needle (not shown in the figure) can be used to guide the positive electrode sheet, the negative electrode sheet and the separator between the positive electrode sheet and the negative electrode sheet for winding, forming a through hole 43 that axially penetrates the roll core 4. Specifically, the positive electrode tab 41 of the roll core 4 is led out from the positive electrode sheet on the periphery of the roll core and connected to the lower surface of the positive electrode shell cover 13; the negative electrode tab 42 of the roll core 4 is led out from the negative electrode sheet on the periphery of the roll core and connected to the inner wall of the negative electrode shell 11. In order to ensure the reliability of the electrical connection and avoid short circuits, adhesive tape (not shown in the figure) can be bonded to the area where the positive electrode tab 41 and the negative electrode tab 42 are located for protection, which can be specifically implemented using existing technologies. This is not limited to the embodiments of the present application.

[0054] The positive electrode mounting member 2 is embedded in the through hole 43 at one end of the winding core 4 from the positive electrode case cover 13 side, and is electrically connected to the positive electrode case cover 13; the negative electrode mounting member 3 is embedded in the through hole 43 at the other end of the winding core 4 from the bottom wall side of the negative electrode case, and is electrically connected to the bottom wall of the negative electrode case 11. In this way, a connection terminal electrically connected to an external circuit is formed based on the positive electrode mounting member 2 and the negative electrode mounting member 3.

[0055] As shown in the figure, the positive electrode mounting member 2 includes a barrel and a flange. A first threaded hole 21 is formed on the barrel, and the first threaded hole 21 is a threaded blind hole. The flange is located on the opening side of the threaded blind hole. The barrel portion is embedded in the through hole 43 located at one end of the winding core 4, and is welded and fixed to the positive electrode shell cover 13 through the flange to ensure the sealing and connection effect. Similarly, the negative electrode mounting member 3 includes a barrel and a flange. A second threaded hole 31 is formed on the barrel, and the second threaded hole 31 is a threaded blind hole. The flange is located on the opening side of the threaded blind hole. The barrel portion is embedded in the through hole 43 located at the other end of the winding core 4, and is welded and fixed to the bottom wall of the negative electrode shell 11 through the flange.

[0056] In other possible implementations, the first threaded hole 21 on the positive electrode mounting member 2 and the second threaded hole 31 on the negative electrode mounting member 3 may also be threaded through holes arranged therethrough, rather than being limited to the threaded blind holes shown in the figure.

[0057] In addition, the positive electrode mounting member 2 and the negative electrode mounting member 3 may also adopt other structural forms, for example, a cylindrical structure without a flange edge may be adopted, as long as the electrical connection function of the corresponding threaded hole segment can be realized, and the embodiment of the present application is not limited. In other possible implementations, the first threaded hole and the second threaded hole may also be integrally formed with the corresponding shell portion (not shown in the figure), for example but not limited to, the first shell portion extends into the through hole of the winding core to form the first threaded hole, and the second shell portion extends into the through hole of the winding core to form the second threaded hole.

[0058] When in use, based on the threaded hole sections on the positive electrode mounting member 2 and the negative electrode mounting member 3, the button battery 10 and the conductive member can be assembled and fixed by tightening the external threads of the corresponding fasteners, and can be electrically connected to the corresponding conductive member through the fasteners.

[0059] In order to keep the button battery 10 in a stable assembled state, the first threaded hole 21 on the positive electrode mounting member 2 and the second threaded hole 31 on the negative electrode mounting member 3 can be threads with the same direction of rotation. For example, the first threaded hole 21 on the positive electrode mounting member 2 and the second threaded hole 31 on the negative electrode mounting member 3 are both right-handed threads, or both are left-handed threads. In this way, when the button battery has a tendency to rotate in any direction, there is a threaded adapter on one side that can limit its rotation, and while maintaining a stable assembled fixed state, the reliability of the corresponding electrical connection can also be guaranteed.

[0060] See also Figure 6 , which is a schematic diagram of an application scenario of the button battery implemented in this application. The figure shows the whole assembly relationship of a Bluetooth headset 100a.

[0061] Figure 6 As shown in , the button battery 10 is located in the housing 90 of the Bluetooth headset 100a, and its positive and negative electrodes are electrically connected to the power-consuming side through the first conductive member 51 and the second conductive member 52, respectively. For example but not limited to, the button battery 10 is connected to the power supply circuit integrated on the circuit board 80 through the first conductive member 51 and the second conductive member 52, and the power supply circuit is used to supply power to each power device of the Bluetooth headset 100a. That is, an electrical connection with the load is achieved. Of course, in other possible specific implementations, the button battery can also be directly electrically connected to the load.

[0062] Two brackets 60 are fixedly arranged in the housing 90, and the button battery 10 is arranged between the two brackets 60. Two screws 70 pass through the through openings 601 of the corresponding brackets 60 and are threadedly adapted to the threaded hole sections of the button battery 10 respectively. That is, the two screws 70 are respectively the first fastener and the second fastener. As two screws 70 of fasteners, one screw 70 passes through the side bracket 60 and is threadedly adapted to the first threaded hole 21 on the positive electrode mounting side of the button battery 10, and the other screw 70 passes through the side bracket 60 and is threadedly adapted to the second threaded hole 31 on the negative electrode mounting side of the button battery 10, and the button battery 10 is fixed by tightening the screws 70. In a specific implementation, the bracket can be made of non-metallic material to protect the battery and insulate it. The bracket 60 can be integrally formed with the housing 90, for example but not limited to, it can be integrally formed with the front shell or the middle shell of the housing 90.

[0063] Based on the threaded matching relationship between the screw 70 and the positive and negative electrode mounting parts of the button battery 10, the electrical connection end of the first conductive member 51 and the electrical connection end of the second conductive member 52 can be clamped and fixed by the corresponding screw 70, and establish corresponding electrical connections respectively. Figure 6 As shown, the electrical connection end of the first conductive member 51 and the electrical connection end of the second conductive member 52 are respectively clamped and fixed with the corresponding bracket 60 through the nut of the screw 70. At the same time, the two conductive members are respectively electrically connected to the positive and negative electrodes of the button battery 10 through the screw 70 and the corresponding mounting members (positive electrode mounting member 2 and negative electrode mounting member 3).

[0064] In a specific implementation, the first conductive member 51 and the second conductive member 52 can be cables with an insulating outer sheath outside the conductor, or can be FPC. One end of the conductor of the cable and FPC is fixed to the positive electrode mounting member 2 and the negative electrode mounting member 3 by screws 70, and the other end of the conductor can be welded to the circuit board 80.

[0065] In order to improve the reliability of the electrical connection of the conductive member, in a specific implementation, the electrical connection end between each conductive member 5 (the first conductive member 51 and the second conductive member 52) and the button battery can be a metal connecting piece. Figure 7 and Figure 8 ,in, Figure 7 A schematic diagram of the structure of an electrical connection end of a conductive member provided in an embodiment of the present application, Figure 8 for Figure 7 A schematic diagram of the assembly relationship of the electrical connection ends of the conductive member described in .

[0066] like Figure 7 As shown, the metal connecting piece 53 as the electrical connection end of the conductive member 5 can be connected to the conductor 54 of the conductive member 5, and can be fixed by welding. The metal connecting piece 53 has a mounting hole 531 and is in the shape of a ring.
