Description

Technical Field

[0001] This utility model relates to the field of battery structure technology, and in particular to a battery. Background Technology

[0002] With the continuous development of battery technology, batteries are being used in increasingly diverse applications, making battery safety a growing concern. During battery design and manufacturing, all internal components must be precisely installed to ensure battery performance and safety. However, existing batteries often have insulation sheets installed incorrectly, a problem that directly impacts battery safety.

[0003] In traditional battery structures, insulating sheets are typically used to isolate conductive components inside the battery to prevent short circuits. However, due to improper handling during manufacturing or flawed design, insulating sheets may be installed backwards, rendering them ineffective. In this case, the positive and negative terminals of the battery may come into direct contact, creating a short circuit and potentially leading to overheating, smoke, or even explosion or fire.

[0004] Therefore, how to effectively prevent the insulating sheet from being attached backwards and improve the overall safety of the battery has become an urgent problem to be solved in the battery design and manufacturing process. Utility Model Content

[0005] One objective of this invention is to provide a battery that addresses the technical problem of how to effectively prevent the insulating sheet from being attached backwards, thereby improving the overall safety of the battery.

[0006] To achieve the above objectives, the present invention provides a solution as follows: a battery comprising a battery body; an identification code disposed on the battery body; and an insulating sheet connected to the side of the battery body on which the identification code is disposed. The insulating sheet has a first window. When the insulating sheet is mounted upright, the projection of the first window onto a reference plane covers the projection of the identification code onto the reference plane. When the insulating sheet is mounted in reverse, the insulating sheet covers at least part of the identification code. The reference plane is parallel to the plane on which the identification code is located.

[0007] Optionally, the area of ​​the first window on the reference plane is m1, and the area of ​​the identification code on the reference plane is m2, where m2 <m1≤1.5m2。

[0008] Optionally, when the insulating sheet is mounted upright, the projection of the geometric center of the first window onto the reference plane coincides with the projection of the geometric center of the identification code onto the reference plane.

[0009] Optionally, the cross-section of the first window parallel to the reference plane is rectangular.

[0010] Optionally, the battery also includes a temperature sensor, which is connected to the side of the battery body with an identification code; the insulating sheet has a second window, and when the insulating sheet is mounted upright, the projection of the second window on the reference plane covers the projection of the temperature sensor on the reference plane.

[0011] Optionally, the projected area of ​​the second window on the reference plane is smaller than the projected area of ​​the identification code on the reference plane.

[0012] Optionally, the identification code includes multiple identification blocks distributed at the edges and geometric center of the identification code for identification by the detection device.

[0013] Optionally, when the insulating sheet is mounted upright, the projection of the first window onto the reference plane covers the projections of all identification blocks onto the reference plane; when the insulating sheet is mounted in reverse, the insulating sheet covers at least one identification block.

[0014] Optionally, the battery also includes a cover plate, which is movably connected to an insulating sheet to cover or open the first and second windows.

[0015] Optionally, the battery pack also includes a cover that seals the first window and is light-transmitting.

[0016] The beneficial effects of this utility model are as follows:

[0017] Compared to existing technologies, this application sets an identification code on the battery body and opens a first window on the insulating sheet opposite the identification code. By utilizing the interaction between the identification code and the first window, the issue of whether the insulating sheet is installed correctly or incorrectly is transformed into whether the identification code can be recognized by the testing equipment. This provides a simple and reliable way to prevent incorrect installation of the insulating sheet. When the insulating sheet is installed correctly, the identification code is fully exposed in the first window, allowing the testing equipment to successfully identify the battery. When the insulating sheet is installed incorrectly, the identification code is completely or partially covered, and the testing equipment cannot perform normal identification in this case, issuing an alarm or prompt to remind the user to reinstall the insulating sheet.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a battery provided in an embodiment of the present invention.

[0026] This utility model provides a battery designed to prevent the insulating sheet 30 from being installed backwards, thereby improving the overall safety of the battery. The battery includes a battery body 10, an identification code 20, and an insulating sheet 30. The identification code 20 is located on one side of the battery body 10 and serves as an important identifier for confirming the installation status, effectively preventing safety hazards caused by incorrect installation.

[0027] The insulating sheet 30 is connected to the side of the battery body 10 where the identification code 20 is located, and a first window 31 is provided on the insulating sheet 30. The first window 31 is designed to ensure that the identification code 20 can be recognized by the detection equipment when correctly installed. When the insulating sheet 30 is installed correctly, the projection of the first window 31 on the reference plane will accurately cover the projection of the identification code 20 on the reference plane, so that the identification code 20 can be fully exposed in the first window 31 for scanning and recognition by the detection equipment. At this time, the detection equipment can successfully complete the identification of the battery, ensuring the various functions and safety of the battery. In this embodiment, the reference plane is parallel to the plane where the identification code 20 is located. Figure 1 The plane A shown is the reference plane.

[0028] However, when the insulating sheet 30 is installed reversely, due to the offset of the position of the first window 31 of the insulating sheet 30, the identification code 20 is completely or partially covered. At this time, the identification code 20 cannot be recognized through the first window 31, or even if part of the identification code 20 enters the range of the first window 31, the detection device still cannot accurately recognize its content due to being blocked. In this case, the detection device cannot perform normal recognition and will issue an alarm or prompt to remind the user to reinstall the insulating sheet 30.

[0029] In this embodiment, by using the method of matching the identification code 20 with the first window 31, a simple and reliable way is provided to prevent the wrong installation of the insulating sheet 30. The correct or reverse installation of the insulating sheet 30 is converted into the problem of whether the identification code 20 can be recognized by the detection device. The correct installation of the insulating sheet 30 corresponds to the normal recognition of the identification code 20, and the reverse installation of the insulating sheet 30 corresponds to the inability of the detection device to recognize the identification code 20, thus helping the staff to quickly find the insulating sheet 30 with abnormal installation, which not only improves the safety performance of the battery, but also enhances the intelligent management in the battery production and use process.

[0030] Further, in some embodiments, the area of the first window 31 on the reference plane is m1, and the area of the identification code 20 on the reference plane is m2, where m2 < m1 ≤ 1.5m2. By defining the relationship between the projected areas of the first window 31 and the identification code 20 on the reference plane, the installation and detection accuracy of the battery is optimized, ensuring that when the insulating sheet 30 is correctly installed, the recognition work can be completed efficiently and accurately.

[0031] In this embodiment, the area of m1 is appropriately increased compared with the area m2 of the identification code 20 to ensure that even when the installation position of the insulating sheet 30 is slightly deviated, the identification code 20 can be effectively recognized through a part of the first window 31, avoiding the risk that the identification code 20 cannot be recognized at all and improving the fault tolerance during installation. The maximum projected area of the first window 31 on the reference plane does not exceed 1.5 times that of the identification code 20, ensuring that the first window 31 is large enough to accommodate the complete range of the identification code 20 and not too loose to effectively avoid wrong installation.

[0032] In some embodiments, the position of the first window 31 is defined to optimize the assembly accuracy and safety of the battery assembly. Specifically, when the insulating sheet 30 is correctly installed, the projection of the geometric center of the first window 31 on the reference plane coincides completely with the projection of the geometric center of the identification code 20 on the reference plane to achieve the accurate alignment of the insulating sheet 30 and the identification code 20.

[0033] In this embodiment, the geometric center of the first window 31 and the geometric center of the identification code 20 are projected onto the reference plane, ensuring that when the insulating sheet 30 is correctly installed, the central position of the first window 31 is perfectly aligned with the position of the identification code 20. This design ensures that the identification code 20 is fully exposed within the first window 31, facilitating successful identification by the detection device. The advantage of this embodiment lies in its fault tolerance; due to the alignment of the geometric centers, deviations during installation are minimized, effectively reducing identification errors caused by inaccurate alignment and further improving battery safety and installation accuracy.

[0034] Furthermore, in some embodiments, the shape of the first window 31 is optimized so that the cross-section of the first window 31 on the reference plane is rectangular. The core purpose is to match the shape of the identification code 20 and the temperature collector 40, since the identification code 20 and the temperature collector 40 typically have rectangular geometry. Using a rectangular window allows for more accurate and efficient exposure and identification of these critical components.

[0035] In this embodiment, the identification code 20 and the temperature sensor 40 are typically rectangular in shape because rectangles offer good arrangement efficiency and space utilization, and can adapt to different size and orientation requirements. By designing the first window 31 as a rectangle, unnecessary gaps in the window opening can be effectively avoided, thereby maximizing the exposure of the identification code 20 and the temperature sensor 40 in the correct position and orientation for accurate identification by the detection device. When the first window 31 matches the geometry of the identification code 20 and the temperature sensor 40, the detection device can more accurately locate and read the identification information, improving the accuracy and efficiency of battery detection.

[0036] In some embodiments, please refer to Figure 2 , Figure 2 This is a schematic diagram of another battery structure provided in this embodiment of the present invention. The battery also includes a temperature sensor 40, which is connected to the side of the battery body 10 where the identification code 20 is located. To further optimize the function of the insulating sheet 30, a second window 32 is also provided on the insulating sheet 30. When the insulating sheet 30 is mounted upright, the projection of the second window 32 on the reference plane completely covers the projection of the temperature sensor 40 on the reference plane, allowing the temperature sensor 40 to be exposed through the second window 32 and operate normally.

[0037] In this embodiment, compared to a single-window design, a multi-window structure is adopted. By setting a first window 31 and a second window 32, the detection methods for the orientation of the insulating sheet 30 are further enriched. The first window 31 is responsible for detecting the installation direction of the insulating sheet 30 in conjunction with the identification code 20, while the second window 32 provides additional detection basis and safety assurance by utilizing its sequential relationship with the first window 31.

[0038] The addition of the second window 32 provides a completely new detection method for determining the orientation of the insulating sheet 30. Specifically, the orientation of the insulating sheet 30 can be determined based on the positions of the first window 31 and the second window 32. For example, if the first window 31 is on the left and the second window 32 is on the right, the insulating sheet 30 is correctly positioned; otherwise, it is reversed. This difference in positional order provides a more intuitive basis for judgment.

[0039] Furthermore, exposing the temperature sensor 40 through the second window 32 effectively reduces interference from the insulating sheet 30 material on temperature signal transmission, improving the accuracy of temperature acquisition. The second window 32 allows the temperature sensor 40 to directly contact the working environment, enabling rapid response to temperature changes and enhancing the real-time performance and accuracy of battery temperature monitoring, thus providing a more reliable guarantee for the safe operation of the battery.

[0040] Furthermore, to prevent the identification code 20 from being misjudged by the detection device through the second window 32 when the insulating sheet 30 is reversed, this embodiment limits the area of ​​the second window 32 so that the projected area of ​​the second window 32 on the reference plane is smaller than the projected area of ​​the identification code 20 on the reference plane.

[0041] In this embodiment, when the projected area of ​​the second window 32 is smaller than the projected area of ​​the identification code 20, the identification code 20 cannot be fully exposed in the second window 32 even when the insulating sheet 30 is installed backwards. This design ensures that the detection device cannot identify the identification code 20 through the second window 32, thereby preventing misjudgment due to misreading of the identification code 20. With this setting, when the detection device is checking the battery, if the identification code 20 is partially or completely obscured, the system will automatically determine that the insulating sheet 30 is installed incorrectly, thereby triggering an alarm or reminding the operator to reinstall the insulating sheet 30.

[0042] In some embodiments, the identification code 20 includes a plurality of identification blocks 21, which are evenly distributed on the edges and geometric center of the identification code 20, aiming to improve the accuracy and reliability of battery identification through multi-point identification. This design not only enhances the fault tolerance of the identification code 20 itself, but also improves the fault tolerance of alignment during battery assembly, ensuring that even if slight deviations occur during battery installation, the detection device can still successfully complete battery identification.

[0043] In this embodiment, the layout of the multiple identification blocks 21 takes into account possible deviations and changes during battery installation. Even if a portion of the identification code 20 is obscured or deviates from the detection area, as long as the identification block 21 is not obscured, it can provide effective identification information, ensuring that the detection device can identify the battery's installation status and reducing the risk of misidentification.

[0044] Furthermore, when the insulating sheet 30 is mounted upright, the projection of the first window 31 onto the reference plane needs to completely cover the projections of all identification blocks 21 in the identification code 20, thereby ensuring that the detection device can simultaneously identify all identification blocks 21 and complete the correct identification of the battery. However, when the insulating sheet 30 is mounted in reverse, the insulating sheet 30 will cover at least one identification block 21, causing the detection device to be unable to identify the complete identification code 20, thus failing to complete the identification work.

[0045] In this embodiment, the identification of the identification code 20 depends on the complete exposure of all identification blocks 21. Identification can only be successfully completed when all identification blocks 21 are detected. During reverse installation, any obstruction of any identification block 21 will cause identification failure. This means that the first window 31 must ensure that all identification blocks 21 of the identification code 20 are fully exposed when the insulating sheet 30 is installed correctly, ensuring that the detection device can correctly read the information of all identification blocks 21. Once any identification block 21 of the identification code 20 is obstructed, the detection device will be unable to complete the full identification task, and therefore the system will trigger an alarm to remind the operator to reinstall the insulating sheet 30.

[0046] In some embodiments, the battery further includes a cover plate 50, which is movably connected to an insulating sheet 30 and can close or open the first window 31 and the second window 32 when needed. This not only enhances the flexibility during battery assembly and use but also provides better protection and safety.

[0047] In this embodiment, the cover plate 50, as a movable component, can be adjusted in position according to actual needs, closing or opening the first window 31 and the second window 32 on the insulating sheet 30. The function of the cover plate 50 is to control the exposure state of the windows according to different working states or testing requirements. For example, during battery assembly or production, when testing is required, the cover plate 50 can be opened to expose the first window 31 and the second window 32, ensuring that the testing equipment can successfully identify the identification code 20 and collect temperature information. During battery use, the cover plate 50 can close the windows to prevent external environmental interference or contamination of sensitive internal parts of the battery.

[0048] When the cover 50 seals the first window 31 and the second window 32, it effectively protects the window area from external substances, dust, or other environmental factors, preventing potential damage or contamination and ensuring the battery remains in good condition during transportation or storage. In particular, for the identification code 20 and the temperature sensor 40, the sealed cover 50 prevents the influence of external light, moisture, or chemicals, reducing misidentification or abnormal temperature acquisition.

[0049] In other embodiments, please refer to Figure 3 , Figure 3This is a top view of another battery provided in this embodiment of the present invention. The battery pack also includes a cover plate 50, which seals the first window 31 and is a light-transmitting structure. This provides a balance between battery safety and ease of inspection. As a protective component, the cover plate 50 effectively seals the first window 31, preventing external substances, dust, moisture, etc., from affecting the internal structure of the battery, thereby improving the overall reliability and stability of the battery.

[0050] Because the cover 50 is made of a light-transmitting material, it allows inspection equipment or other monitoring devices to observe the area of ​​the first window 31 through the cover 50, ensuring the visibility and operability of the identification code 20. The light-transmitting cover 50 not only maintains protection for internal components but also allows operators or automated inspection systems to perform necessary checks or identifications directly through external observation without fully opening the battery pack.

[0051] In this embodiment, the cover plate 50 with a light-transmitting structure can not only seal the first window 31 and protect the inside of the battery from external interference, but also maintain the visibility and operability of key internal information, thereby improving the management efficiency and safety of the battery.

If the specific posture changes, the directional indicator will also change accordingly.

[0053] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.
