[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] In related technologies, PCB (Printed Circuit Board), also known as printed circuit board or printed circuit board, is an important electronic component. It serves as the support for electronic components and provides electrical connections for them.

[0042] Several battery cells are connected in series and parallel and encased in a plastic frame or Mylar material to form a unified whole, i.e., a multi-cell battery. This encapsulation method is widely used and is the most common traditional encapsulation method for multi-cell batteries. However, the plastic frame used in this encapsulation method is injection molded, which is easily deformed. This can easily cause the locking lugs on the plastic frame to shift, making battery assembly with the entire device difficult and resulting in a high defect rate.

[0043] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, according to the first aspect of the present invention, a battery cell packaging structure is provided. The battery cell packaging structure includes a circuit board 100 and at least one locking lug 120. The circuit board 100 has at least one receiving area 110, the receiving area 110 has a first pad 111 and a battery cell placement groove 112, the battery cell placement groove 112 is defined for accommodating a battery cell; the electrode of the battery cell in the battery cell placement groove 112 is electrically connected to the first pad 111 of the receiving area 110 where it is placed; at least one locking lug 120 is disposed on the circuit board 100.

[0044] In these embodiments, the approach aims to improve the accuracy and reliability of battery assembly while reducing the defect rate. The following is a detailed description of this cell packaging structure:

[0045] As the core component of the battery cell packaging, the circuit board 100 not only undertakes the task of electrical connection but also provides physical support and positioning for the battery cell. At least one accommodating area 110 is designed on the circuit board 100, and each accommodating area 110 includes the following features:

[0046] The first solder pad 111 is used to solder or connect to the tabs (positive and negative leads) of the battery cell, ensuring a stable and reliable electrical connection between the battery cells. The battery cell placement slot 112 is a groove or space designed to accommodate the battery cell, which can accurately position and fix the battery cell, prevent it from moving during transportation or use, and reduce the battery thickness.

[0047] Typically, to enhance the connection stability between the circuit board 100 and the entire machine or other components, at least one locking lug 120 is provided around the periphery of the circuit board 100. The distribution of these locking lugs 120 should be determined according to the installation position of the entire machine to ensure compatibility between the two. For example, the number of locking lugs 120 can be 1, 2, 3, 4, 5, 6, or 7, etc.

[0048] Clearly, using circuit board 100 as the basic component not only provides electrical connection functionality but also includes a dedicated accommodating area 110 for placing battery cells, replacing the traditional plastic frame. Each accommodating area 110 contains a first solder pad 111 and a battery cell placement slot 112, ensuring the battery cell can be correctly positioned and secured, and that the battery cell's terminals can be directly electrically connected to the solder pads on circuit board 100. Furthermore, unlike the traditional plastic frame locking lugs 120, these lugs 120 are directly mounted on circuit board 100. This design reduces the risk of locking lug 120 misalignment due to plastic frame deformation, improving assembly accuracy and reliability.

[0049] Therefore, through the above improvements, this application provides a more stable and reliable cell packaging solution, which helps to simplify the manufacturing process, improve product quality, and reduce production costs.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the cell packaging structure further includes a temperature sensor 130, at least one accommodating area 110 also has a second pad 113, the temperature sensor 130 is disposed on the circuit board 100 and the temperature sensor 130 is close to the tail of the cell, the second pad 113 is close to the temperature sensor 130, and the terminals of the temperature sensor 130 are electrically connected to the second pad 113.

[0051] In these embodiments, the cell packaging structure further integrates a temperature sensor 130, which is a thermistor whose resistance decreases as temperature increases. This structure helps to monitor the battery's temperature status in real time, ensuring that the battery operates within a safe operating temperature range. The following are specific implementation schemes including the temperature sensor 130:

[0052] The second pad 113 is specifically configured for the temperature sensor 130 and is located close to the temperature sensor 130 to facilitate electrical connection of the terminal.

[0053] Temperature sensor 130 is mounted on circuit board 100 and is specifically positioned near the tail end of the battery cell, that is, the end of the cell furthest from the tabs. This is because the tail end of the battery cell is usually one of the parts most prone to heat generation, and placing temperature sensor 130 here allows for more accurate monitoring of temperature changes within the battery cell.

[0054] Clearly, the temperature sensor 130 can detect the cell temperature in real time, providing critical safety information. This is essential for preventing safety issues caused by overheating. The temperature sensor 130 is designed close to the tail of the cell to ensure accurate temperature measurement. Furthermore, the electrical connection between the terminal of the temperature sensor 130 and the second pad 113 ensures stable signal transmission, enabling temperature data to be reliably transmitted to the control system or other monitoring equipment.

[0055] It should be noted that the temperature sensor 130 and the second pad 113 can be easily integrated into the existing circuit board 100 layout without significantly increasing manufacturing complexity. Furthermore, traditional temperature sensors 130 are mostly connected to the first pad 111 via leads, requiring long leads, making assembly difficult, and the long leads are easily broken due to their exposure to the outside. In this application, by setting the second pad 113 on the circuit board 100 near the temperature sensor 130 to achieve electrical connection with the temperature sensor 130, the need for leads or the shortening of the leads is eliminated.

[0056] For example, the number of temperature sensors 130 is set to multiple, such as 2, 3, 4, 5, 6 or 7, etc., to be distributed on the circuit board 100, which can detect the temperature of multiple cells or detect the temperature of multiple locations of a single cell.

[0057] For example, in this embodiment, the temperature sensor 130 is selected as an NTC temperature sensor (Negative Temperature Coefficient temperature sensor). Of course, in other embodiments, the temperature sensor 130 may also be selected as a PTC temperature sensor (Positive Temperature Coefficient temperature sensor), a thermistor, an infrared temperature sensor, etc.

[0058] For example, one accommodating area 110 is provided with a second pad 113. Of course, in other embodiments, the number of accommodating areas 110 provided with the second pad 113 may also be 2, 3, 4, 5 or 6, etc.

[0059] For ease of understanding, the assembly process is provided below:

[0060] First, place the battery cell into the battery cell placement slot 112 on the circuit board 100. Next, solder or connect the battery cell's tabs to the corresponding first pad 111. Install the temperature sensor 130 near the tail of the battery cell and electrically connect its terminals to the second pad 113. Finally, use the locking lugs 120 to ensure that the circuit board 100 can be securely mounted on the target device.

[0061] In other words, by integrating the temperature sensor 130, abnormal temperature conditions can be detected and responded to in a timely manner, improving the safety of battery use. Stable and reliable electrical connections and physical positioning ensure the long-term stability and durability of the entire system.

[0062] like Figure 1 and Figure 2As shown, in some embodiments, the terminals of the temperature sensor 130 and the second pad 113 are welded and fixed.

[0063] In these embodiments, to ensure the stability and reliability of the connection between the temperature sensor 130 and the circuit board 100, the terminals of the temperature sensor 130 and the second pad 113 are directly soldered together. The terminals of the temperature sensor 130 are directly soldered onto the second pad 113, forming a robust electrical connection. This soldering method offers the following advantages:

[0064] Welding provides robust mechanical connections and low-resistance electrical connections, ensuring stable signal transmission and maintaining good performance even under vibration or shock environments. Welded joints have good durability, maintaining a stable connection over extended periods and reducing problems caused by poor contact. Furthermore, welding is a mature technology that can be completed quickly and efficiently, helping to simplify production processes and improve productivity.

[0065] Furthermore, the terminals of the temperature sensor 130 and the second pad 113 are directly soldered, which eliminates the need for wiring, further saving installation and material costs, and ensuring the reliability of the electrical connection between the two.

[0066] In some embodiments, the electrode tabs of the battery cell are welded to the first solder pad 111.

[0067] In these embodiments, the tabs of the battery cell (i.e., the positive and negative terminals of the battery cell) and the first pad 111 on the circuit board 100 are connected by soldering. This design ensures a robust and reliable electrical connection between the battery cell and the circuit board 100, and provides a low-resistance current path, thereby optimizing battery performance and improving the overall reliability of the system.

[0068] In other words, the battery cell tabs are directly soldered to the first pad 111 on the circuit board 100, forming a robust mechanical connection and a low-resistance electrical connection. Soldering provides a robust mechanical connection and a low-resistance electrical connection, ensuring stable signal transmission and maintaining good performance even under vibration or shock environments. The solder joint has good durability, maintaining a stable connection state for a longer period of time and reducing problems caused by poor contact. Soldering is a mature technology that can be completed quickly and efficiently, helping to simplify the production process and improve production efficiency.

[0069] Furthermore, the good conductivity of the solder joints reduces heat generation, which helps improve the thermal management of the battery cell and extend its service life.

[0070] In some embodiments, the cell placement slot 112 is configured as a through slot.

[0071] In these embodiments, the cell placement slot 112 is a through slot, that is, a slot that runs through the circuit board 100, which helps to optimize the overall performance and manufacturing process of the battery packaging structure.

[0072] The through-slots allow for airflow or can be filled with heat-dissipating material, helping to improve the heat dissipation efficiency of the battery cells and prevent overheating. Furthermore, during assembly, the through-slots allow the battery cells to be inserted from one side of the circuit board 100 and exposed from the other, simplifying the assembly process and improving production efficiency. Additionally, the ability to easily remove the battery cells from one side facilitates subsequent maintenance and cell replacement.

[0073] Furthermore, through slots can form weight-reducing holes, thereby reducing the weight of the battery.

[0074] In some embodiments, the lock lug 120 has a lock lug hole 121.

[0075] In these embodiments, the locking lug 120 is in the form of a locking lug hole 121, which allows the locking lug 120 to not only provide a secure mechanical connection, but also to be fixed or aligned with other components or mounting locations via the locking lug hole 121. Each locking lug 120 has at least one locking lug hole 121, which can be used with screws, bolts, or other fasteners to firmly fix the circuit board 100 to the whole machine or other components, improving the stability of the overall structure. The locking lug hole 121 helps ensure precise alignment between the circuit board 100 and other components, reducing errors during assembly and improving assembly accuracy.

[0076] When the battery needs repair or replacement, the circuit board 100 can be quickly removed by simply removing the retainer, simplifying the maintenance process.

[0077] For example, the number of lock lug holes 121 on the lock lug 120 can be set to 1, 2, 3 or 4, etc. The specific number of lock lug holes 121 on each lock lug 120 is not specifically limited here, and is selected according to the actual installation location.

[0078] In some embodiments, the peripheral side of the circuit board 100 has a protrusion that defines a latch 120.

[0079] In these embodiments, the latch 120 is part of the circuit board 100, meaning that the two are integrated and can be directly manufactured as a single unit. This design not only simplifies the manufacturing process of the latch 120 but also enhances the connection stability between the circuit board 100 and the external structure.

[0080] Therefore, the lock lug 120 is integrally formed with the circuit board 100, reducing the need for additional parts and simplifying the production and assembly process. The raised design makes the lock lug 120 more robust, able to withstand greater mechanical stress, and improves the stability of the overall structure. Furthermore, since the lock lug 120 and the circuit board 100 are integrated, more precise alignment can be ensured, reducing assembly errors.

[0081] Furthermore, compared to traditional plastic frame lock lugs 120, the lock lugs 120 defined by the protrusion are less prone to deformation. The lug holes are designed on the circuit board 100, and the hole position accuracy of the circuit board 100 can reach ±0.1mm, ensuring dimensional stability. This further reduces assembly difficulty and defect rate.

[0082] It should be noted that the protrusions on the periphery of the circuit board 100 are designated as lock lugs 120, which also paves the way for the subsequent removal of lock lugs 120. The corresponding lock lugs 120 can be removed simply by cutting off the protrusions that are not needed.

[0083] In some embodiments, there are multiple locking lugs 120, which are removably disposed on the periphery of the circuit board 100. The multiple locking lugs 120 are divided into N types according to their distribution positions. Each type of locking lug 120 can be connected to at least one type of mounting position, so that the circuit board 100 can be adapted to at least N types of mounting positions, and satisfies: N≥1, where N is a positive integer.

[0084] In these embodiments, a plurality of locking lugs 120 are provided on the periphery of the circuit board 100. These locking lugs 120 can be selectively retained or removed as needed, providing great flexibility; that is, redundant locking lugs 120 can be removed and effective locking lugs 120 can be retained depending on the actual installation location.

[0085] Based on their distribution locations, the latches 120 are divided into N types, and each type of latch 120 can be connected to at least one type of mounting location. Ensuring that the circuit board 100 can adapt to at least N types of mounting locations (N≥1) enhances versatility and applicability. In other words, by dividing them into N types according to their distribution locations, each type of latch 120 is suitable for different installation environments. Unwanted latches 120 can be removed through specific processes, such as cutting or breaking, simplifying the customization process for different installation needs. For example, N can be 1, 2, 3, 4, 5, 6, 7, or 8, etc.

[0086] When designing the circuit board 100, the positions and types of different types of locking lugs 120 are planned in advance to ensure that it can adapt to various installation locations. The circuit board 100 is manufactured using an integrated production process, making the locking lugs 120 an integral part of the circuit board 100, while also providing options for removal. Depending on specific installation requirements, some locking lugs 120 can be selectively retained or removed to ensure optimal installation results. Screws, bolts, and other fasteners are used to further secure the circuit board 100 through the locking lug holes 121, ensuring its stable installation on the target equipment.

[0087] Clearly, the availability of multiple locking lugs 120 allows for flexible selection based on actual installation needs, increasing the application range of the encapsulation structure, i.e., its versatility. Different types of locking lugs 120 can be adapted to various installation locations, reducing problems caused by size mismatches.

[0088] For example, there are multiple locking lugs 120, and the entire device has three locations where batteries need to be installed, meaning the entire device has three installation positions. Therefore, the multiple locking lugs 120 can be preset into three types according to actual needs. Thus, by selecting the corresponding type of locking lug 120 for connection based on the installation position, there is no need to manufacture three different types of circuit boards 100, saving costs. Of course, in other embodiments, the entire device has two locations where batteries need to be installed, in which case the multiple locking lugs 120 can be preset into two types, and so on.

[0089] like Figure 3 and Figure 4 As shown, in some embodiments, the cell packaging structure further includes a label, which is affixed to the circuit board 100 and covers at least the front and back sides of the circuit board 100.

[0090] In these embodiments, the cell packaging structure also includes a label affixed to the circuit board 100 and covering at least the front and back sides of the PCB. This design not only enhances the product's aesthetics and identifiability but also provides an additional protective layer and secures the cell to the circuit board 100.

[0091] Labels provide an extra layer of physical protection for PCB boards, preventing scratches, dust, and other external contaminants. Labels can be printed with brand logos, product information, warning labels, etc., improving the product's appearance and user recognition. Furthermore, high-quality label materials can offer some water and moisture resistance, extending the PCB board's lifespan.

[0092] Of course, labeling materials with good heat dissipation or insulation properties help improve the thermal management and electrical safety of the cell packaging structure.

[0093] like Figure 3 and Figure 4As shown, in some embodiments, the label includes a front label 140 and a back label 150. The front label 140 is affixed to the front of the circuit board 100, and the back label 150 is at least partially affixed to the back of the circuit board 100 and the edge of the front of the circuit board 100.

[0094] In these embodiments, the label is designed to include a front label 140 and a back label 150, wherein the front label 140 is affixed to the front of the circuit board 100, and the back label 150 is at least partially affixed to the back of the circuit board 100 and the edge of the front of the circuit board 100, that is, the label is configured as a split structure.

[0095] The front label 140 is affixed to the front of the PCB board, covering the main components and solder joints, serving both a protective and identification function.

[0096] The back label 150 is at least partially affixed to the back of the circuit board 100 and extends to the edge of the front of the circuit board 100, forming a continuous protective layer. A portion of the back label 150 wraps around the edge of the front of the circuit board 100 to ensure a seamless connection between the two labels and prevent moisture, dust, etc. from entering from the edge.

[0097] It should be noted that the front label 140 and back label 150 are customized according to the specific size and shape of the PCB board to ensure that they can completely cover the designated area without affecting the function of the battery cells and other components.

[0098] According to a second aspect disclosed in this utility model, a battery module is provided, the battery module including a cell packaging structure.

[0100] For example, the battery module could be a lithium battery, which is particularly lightweight and can be used to power digital cameras, mobile phones, etc. With the recent surge in the popularity of personal portable devices such as smartphones and tablet PCs, lithium batteries are actually the most widely used. However, it is not limited to this type; other types of batteries are also included in the protection scope, such as lead-acid batteries and nickel-metal hydride batteries.

[0101] According to a third aspect disclosed in this utility model, an electrical device is provided, which includes a battery module.

[0102] Since the aforementioned battery module possesses the aforementioned technical effects, the electrical device including this battery module should also possess the same technical effects, which will not be elaborated further here.
