[0002] Traditional lithium battery connection methods typically involve connecting the battery to the circuit board of the device using wires or flexible printed circuit boards. This is not only complex to operate, but also prone to output terminal misalignment during assembly, resulting in inaccurate and unreliable connection between the lithium battery and the device's control circuit board. This is especially problematic when connecting smaller batteries to the device's control circuit board.

[0003] For example, the Chinese patent application CN201721495691.2, filed by Huizhou Hengtai Technology Co., Ltd., addresses the issue that due to space constraints and precision requirements within electrical equipment, connecting too many components to the circuit board connected to the battery assembly increases the difficulty of battery assembly. Furthermore, the assembly process can only be completed manually, making automation difficult and increasing labor costs. Manual assembly also suffers from low efficiency and inconsistent quality, easily leading to connection deviations between the battery and the electrical equipment, thus affecting the overall quality and reliability of the product.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 3 As shown, an integrated battery pack structure 10 according to an embodiment of this disclosure includes a battery assembly 100 and an electrical connection assembly 200, with the battery assembly 100 fixedly connected to the electrical connection assembly 200. The electrical connection assembly 200 includes an integrated circuit board 210, an output terminal assembly 220, and a conductive component 230. The battery assembly 100 is fixedly connected to one side of the integrated circuit board 210. The integrated circuit board 210 has a first terminal through-hole 2101 and a second terminal through-hole 2102. The output terminal assembly 220 includes a first connector 221 and a second connector 222. The first connector 221 passes through the first terminal through-hole 2101, and the second connector 222 passes through the second terminal through-hole 2102. The conductive component 230 is soldered to the end face of the integrated circuit board 210 adjacent to the battery assembly 100. The conductive component 230 is used to form an electrical connection with the positive and negative terminals of the battery assembly 100.

[0030] In this embodiment, the battery assembly 100 is fixedly connected to one side of the integrated circuit board 210. The conductive electronic component 230 on the integrated circuit board 210 is tightly connected to the positive and negative terminals of the battery assembly 100, thereby enabling the battery assembly 100 to output electrical energy to the integrated circuit board 210. Furthermore, the first connector 221 and the second connector 222 are connected to the integrated circuit board 210 and can be connected to the control circuit board of the electrical device, thereby enabling the battery assembly 100 to provide electrical energy to the electrical device. Specifically, compared with the traditional battery pack structure, the integrated battery pack structure 10 of this embodiment forms a fixed connection between the battery assembly 100 and the integrated circuit board 210, and uses the output terminal component 220 to replace the traditional wires or flexible circuit boards to form an electrical connection with the control circuit board of the electrical device. This reduces soldering work and lowers the risk of cold solder joints when soldering wires. Furthermore, since the output terminal component 220 can be quickly and accurately assembled and connected to the control circuit board of the electrical device, the connection process with the electrical device is simplified. In addition, the integrated battery pack structure 10 integrates components from a traditional circuit board into the battery assembly 100, thereby simplifying the spatial structure on the integrated circuit board 210 and facilitating the assembly of the integrated battery pack structure 10.

[0031] The aforementioned integrated battery pack structure 10 achieves precise connection with the control circuit board of the electrical device through the output terminal assembly 220, avoiding the problem of output terminal position deviation that is prone to occur in traditional connection methods, and enabling rapid assembly of the integrated battery pack structure 10 with the electrical device. Furthermore, some components of the integrated battery pack structure 10 are integrated within the battery assembly 100, thereby simplifying the external spatial structure of the integrated circuit board 210, making the design of the integrated circuit board 210 more compact. This facilitates the assembly of the integrated battery pack structure 10 into small electrical devices, thus improving the adaptability of the integrated battery pack structure 10. Simultaneously, since the output terminal assembly 220 replaces traditional wires or flexible circuit boards to form an electrical connection with the control circuit board of the electrical device, the connection process is simplified and assembly automation is facilitated, thereby reducing the production cost of the integrated battery pack structure 10 and improving its production efficiency.

[0032] like Figures 1 to 3 As shown, in one embodiment, the battery assembly 100 has a receiving groove 1001, and a portion of the integrated circuit board 210 is disposed within the receiving groove 1001. In this embodiment, the shape and size of the receiving groove 1001 match a portion of the integrated circuit board 210, ensuring that the integrated circuit board 210 can be accurately embedded therein, making the entire integrated battery pack structure 10 more compact. Furthermore, since the integrated circuit board 210 is partially embedded within the receiving groove 1001, the volume of the integrated battery pack structure 10 is effectively controlled, making it easier to assemble into small electrical devices, thereby improving the space utilization of the integrated battery pack structure 10.

[0033] like Figures 1 to 3 As shown, in one embodiment, the conductive component 230 includes a positive conductive element 231 and a negative conductive element 232. The positive conductive element 231 and the negative conductive element 232 are respectively disposed opposite to and spaced apart on the integrated circuit board 210. The positive conductive element 231 is used to connect to the positive terminal of the battery assembly 100, and the negative conductive element 232 is used to connect to the negative terminal of the battery assembly 100. In this embodiment, when the battery assembly 100 and the integrated circuit board 210 are connected through the conductive component 230, the positive conductive element 231 is tightly attached to the positive terminal tab of the battery assembly 100, and the negative conductive element 232 is tightly attached to the negative terminal tab of the battery assembly 100. This tight connection ensures the transmission of electrical energy while reducing contact resistance and improving the efficiency of the electrical connection. Furthermore, the opposite and spaced arrangement of the positive conductive element 231 and the negative conductive element 232 effectively prevents short circuits. On the other hand, during the assembly process, the electrical connection can be completed simply by aligning and pressing the positive and negative tabs of the battery assembly 100 with the positive conductive part 231 and the negative conductive part 232, respectively. This simplifies the assembly steps and improves the ease of assembly.

[0034] like Figures 1 to 3 As shown, in one embodiment, at least one of the positive electrode conductive element 231 and the negative electrode conductive element 232 is a square conductive element. In this embodiment, the square conductive element has a flat and regular contact surface, which allows it to provide more stable and uniform contact pressure when in contact with the positive or negative electrode tab of the battery assembly 100. Furthermore, during assembly, when the square conductive element is pressed against the positive electrode tab of the battery assembly 100, its flat contact surface ensures good electrical contact with the positive electrode tab, effectively reducing the problem of increased contact resistance caused by uneven contact surfaces, thereby improving the efficiency of power transmission. In addition, its regular shape facilitates accurate alignment of the square conductive element with the positive or negative electrode tab of the battery assembly 100 during assembly, thereby improving assembly accuracy, shortening assembly time, and ultimately enabling efficient automated production of the integrated battery pack structure 10.

[0035] like Figures 1 to 3 As shown, in one embodiment, the positive electrode conductive element 231 and the negative electrode conductive element 232 have the same thickness. In this embodiment, the identical thickness of the positive electrode conductive element 231 and the negative electrode conductive element 232 ensures consistency during assembly, resulting in more uniform pressure applied when pressing the positive and negative electrodes of the battery assembly 100. This uniform pressure distribution helps ensure the stability of electrical contact, further reducing contact resistance and improving the efficiency of power transmission. Furthermore, the identical thickness of the positive electrode conductive element 231 and the negative electrode conductive element 232 also helps maintain the overall balance of the integrated battery pack structure 10. During long-term use, the identical thickness of the positive electrode conductive element 231 and the negative electrode conductive element 232 prevents uneven stress on the battery assembly 100 on the integrated circuit board 210, thus avoiding deformation or damage to the battery assembly 100, thereby improving the reliability and durability of the integrated battery pack structure 10.

[0036] like Figures 1 to 3 As shown, in one embodiment, the first connector 221 and the second connector 222 are arranged adjacent to each other on one side of the integrated circuit board 210. In this embodiment, the adjacent arrangement of the first connector 221 and the second connector 222 makes the layout of the power terminals on the integrated circuit board 210 more compact, which helps to reduce the overall size of the integrated circuit board 210, thereby making the integrated battery pack structure 10 more compact to fit electrical devices with limited space. In addition, the adjacent arrangement of the first connector 221 and the second connector 222 facilitates connection to the control circuit board of the electrical device through a common fixing structure or connector when making electrical connections with the electrical device, thereby enhancing the connection stability between the connector and the electrical device and reducing electrical signal transmission problems caused by loose connections or poor contact.

[0037] like Figures 1 to 3 As shown, in one embodiment, the first connector 221 and the second connector 222 are of equal length. In this embodiment, because the first connector 221 and the second connector 222 are of the same length, the operator can more easily handle both connectors simultaneously without needing to distinguish and adjust connectors of different lengths, thereby improving assembly efficiency. Furthermore, the consistency in length between the two connectors can serve as a reference during assembly, helping to reduce errors in the assembly process and ensuring the accurate installation of the first connector 221 and the second connector 222.

[0038] like Figures 1 to 3 As shown, in one embodiment, at least one of the first connector 221 and the second connector 222 is a cylindrical connector. In this embodiment, the circumferential surface of the cylindrical connector can tightly fit with the connection hole on the control circuit board of the electrical equipment. During connection operation, the cylindrical connector can be inserted into the corresponding connection hole. Due to its cylindrical shape, the cylindrical connector has a uniform contact area in all directions, making the connection of the cylindrical connector more stable and reliable, thereby reducing the risk of loosening due to vibration, displacement, and other factors. In addition, due to its structural characteristics, the cylindrical connector can more evenly distribute current during current conduction. When current passes through the cylindrical connector, the uniform conductivity of its circumferential surface can effectively reduce current concentration, reduce resistance loss, and thus improve the efficiency of power transmission.

[0039] like Figures 1 to 3 As shown, in one embodiment, the integrated circuit board 210 also has a limiting groove 2103, and a portion of the battery assembly 100 is disposed within the limiting groove 2103. In this embodiment, during the assembly process of the integrated battery pack structure 10, the battery assembly 100 can be accurately engaged within the limiting groove 2103, ensuring that the relative position between the battery assembly 100 and the integrated circuit board 210 remains fixed. Precise positioning simplifies the assembly steps and improves the accuracy and efficiency of assembly. Secondly, when the battery assembly 100 is placed in the limiting groove 2103, because the shape and size of the limiting groove 2103 match a portion of the battery assembly 100, the battery assembly 100 is firmly fixed within the limiting groove 2103, making it less prone to shaking or displacement, thereby ensuring a stable connection between the battery assembly 100 and the integrated circuit board 210, and thus improving the overall stability of the integrated battery pack structure 10. On the other hand, during the assembly operation, the operator only needs to align the corresponding part of the battery component 100 with the limiting groove 2103 to quickly and accurately complete the assembly of the battery component 100 and the integrated circuit board 210, which further improves the accuracy and efficiency of the assembly.

[0040] This application also provides a smart wearable device, including an integrated battery pack structure 10 according to any embodiment. In this embodiment, the battery assembly 100 is fixedly connected to one side of the integrated circuit board 210, and the conductive electronic component 230 on the integrated circuit board 210 is tightly connected to the positive and negative terminals of the battery assembly 100, thereby realizing the output of electrical energy from the battery assembly 100 to the integrated circuit board 210; and the first connector 221 and the second connector 222 are connected to the integrated circuit board 210 and can be connected to the control circuit board of the device, thereby enabling the battery assembly 100 to provide electrical energy to the device. Specifically, compared with the traditional battery pack structure, the integrated battery pack structure 10 of this embodiment forms a fixed connection between the battery assembly 100 and the integrated circuit board 210, and forms an electrical connection with the control circuit board of the device through the output terminal assembly 220 instead of the traditional wires or flexible circuit boards, reducing the soldering work and reducing the risk of cold solder joints when soldering wires. Furthermore, since the output terminal assembly 220 can be quickly and accurately assembled and connected to the control circuit board of the device, the connection process with the device is simplified. In addition, the integrated battery pack structure 10 integrates components from a traditional circuit board into the battery assembly 100, thereby simplifying the spatial structure on the integrated circuit board 210 and facilitating the assembly of the integrated battery pack structure 10.

[0041] Compared with the prior art, this disclosure has at least the following advantages:

[0042] 1. The integrated battery pack structure 10 described above achieves precise connection with the control circuit board of the electrical equipment through the output terminal assembly 220, avoiding the problem of output terminal position deviation that is easy to occur in traditional connection methods, and realizing rapid assembly of the integrated battery pack structure 10 and the electrical equipment.

[0043] 2. In addition, some components of the integrated battery pack structure 10 are integrated into the battery assembly 100, which simplifies the external space structure of the integrated circuit board 210, making the integrated circuit board 210 more compact in design. This is beneficial for assembling the integrated battery pack structure 10 into small electrical equipment, thereby improving the adaptability of the integrated battery pack structure 10.

[0044] 3. Furthermore, since the output terminal assembly 220 replaces the traditional wires or flexible circuit boards to form an electrical connection with the control circuit board of the electrical equipment, the connection process is simplified and assembly automation is facilitated, thereby reducing the production cost of the integrated battery pack structure 10 and improving the production efficiency of the integrated battery pack structure 10.
