Description

Technical Field

[0002] Smart AR glasses are booming. While their hardware shares a similar architecture to smartphones, their functional requirements are more complex and diverse. They must not only capture videos and photos but also deeply integrate virtual reality to provide an immersive user experience. These complex functions rely on processors for massive computational workloads, resulting in high overall power consumption and stringent battery requirements.

[0003] However, as wearable devices, smart AR glasses have strict weight and volume constraints. If the battery is too large and heavy, it will affect wearing comfort and the device's structural balance. Therefore, simply increasing the battery size to increase capacity is not an option. These weight and volume constraints have become a key bottleneck in optimizing battery performance.

When the temples are irregularly designed or curved, the batteries can only store energy in the limited space of the temples, resulting in low space utilization. This significantly reduces the potential for battery capacity expansion and makes it difficult to achieve a capacity breakthrough. Summary of the Invention

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0039] The present invention provides a temple, a method for manufacturing a temple, and smart glasses, aiming to improve battery life within a limited space. A detailed description is provided below with reference to the accompanying drawings.

[0040] See also Figure 1 , Figure 1 A schematic diagram of the structure of the smart glasses provided in an embodiment of the present application.

[0041] The present invention provides a temple 10 for use with a near-eye display device, such as smart glasses 100. In smart glasses 100, the temples 10 are located on either side of a frame 20, are used to support the overall structure of the glasses by resting on the ears, and can accommodate components such as batteries. In addition to their traditional support functions, the temples 10 can also integrate various electronic components to implement specific functions.

[0042] See also Figure 2 as well as Figure 3 , Figure 2 This is a schematic diagram of the first structure of the temples provided in the embodiment of the present application. Figure 3 for Figure 2 The temple 10 includes a battery base cover 11, a battery cell 12, a battery packaging cover 13, an electrolyte, and a temple cover 14.

[0043] The battery base cover 11 is provided with a receiving groove 111. The receiving groove 111 is a groove structure of a certain depth and shape formed on the battery base cover 11 of the temple 10. Its function is to provide a placement space for components such as the battery cell 12, the battery packaging cover 13, and electronic components, ensuring that these components can be arranged stably and orderly within the temple 10. This structure realizes the functional integration of the temple 10. For example, the depth and width of the receiving groove 111 can be designed in conjunction with the actual size of the battery cell 12, so that the battery cell 12 can partially fit tightly within the receiving groove 111 after installation, preventing shaking during use of the temple 10 and thus ensuring the stability and safety of the battery cell 12.

[0044] See also Figure 4 , Figure 4 A schematic diagram of the second structure of the temples provided in an embodiment of the present application. The battery cell 12 is placed in the receiving groove 111. The battery cell 12 includes a battery cell body 121, a positive electrode ear 122 and a negative electrode ear 123, and the positive electrode ear 122 and the negative electrode ear 123 both protrude from the surface of the battery cell body 121. The battery cell body 121 is the main part where the electrochemical reaction actually occurs to store and release electrical energy. The complex internal microstructure of the battery determines the performance parameters of the battery, such as capacity, charge and discharge efficiency, etc. For example, the use of high-performance positive and negative electrode materials can increase the energy density of the battery cell 12, so that the battery can store more electrical energy at the same volume; and optimizing the structure and material of the diaphragm can reduce the internal resistance of the battery and improve the charge and discharge efficiency.

[0045] See also Figure 5 , Figure 5 Schematic diagram of the structure of the battery cell provided in an embodiment of the present application. The positive electrode ear 122 and the negative electrode ear 123 both protrude from the surface of the battery cell body 121. The positive electrode ear 122 is connected to the positive electrode material in the battery cell 12, and is used to conduct the current generated inside the battery cell 12 to the external circuit; the negative electrode ear 123 is connected to the negative electrode material in the battery cell 12, and is used to conduct the current input from the external circuit into the battery cell 12. The material and structure of the positive electrode ear 122 and the negative electrode ear 123 will affect the internal resistance and conductivity of the battery, and thus affect the charge and discharge efficiency and service life of the battery. For example, using a metal material with good conductive properties to make the positive electrode ear 122 and the negative electrode ear 123, and optimizing their shape and size, can reduce the internal resistance of the battery and improve the current conduction efficiency.

[0046] See also Figure 6 , Figure 6Schematic diagram of the structure of the battery packaging cover provided in an embodiment of the present application. The battery packaging cover 13 is tightly connected to the battery base cover 11, and together they enclose a closed battery shell. The battery base cover 11 and / or the battery packaging cover 13 are made of steel shell material, and are sealed by laser welding technology to improve the sealing and structural strength of the battery shell. The battery shell provides a relatively independent and stable environment for the battery cell 12, which is crucial for the normal operation of the battery. The battery cell body 121 is placed in the battery shell, and the positive electrode ear 122 and the negative electrode ear 123 are exposed outside the battery shell so as to be connected to the external circuit. The exposed pole ears are PACK packaged like conventional batteries to increase the protection circuit. PACK packaging is battery pack packaging, and its full English name is Package. It refers to the process of combining multiple single cells into a battery pack in a series-parallel manner, and performing a series of process treatments such as electrical connection, structural fixation, thermal management design, and safety protection, and finally forming a complete battery system that can be directly applied to various types of equipment.

[0047] The battery packaging cover 13 not only protects the battery cells 12 but also prevents electrolyte leakage, ensuring battery safety and stability. Furthermore, its excellent sealing properties prevent external moisture, oxygen, and other substances from entering the battery and affecting its performance. For example, moisture entering the battery may cause the electrolyte to decompose, generating gas, increasing internal pressure and even causing safety hazards such as battery explosion. Meanwhile, oxygen entering the battery may react with the electrode materials, reducing the battery's capacity and cycle life.

[0048] An electrolyte is injected into the battery case to activate the battery cells 12. The electrolyte conducts ions during the battery's charge and discharge processes and serves as the medium for the electrochemical reactions within the battery cells 12. The performance of the electrolyte directly impacts the battery's charge and discharge efficiency, cycle life, and safety. For example, using an electrolyte with high ionic conductivity can improve battery charge and discharge efficiency and shorten charging time; using an electrolyte with good stability can extend the battery's cycle life and reduce capacity decay during use.

[0049] Please continue reading Figure 2 as well as Figure 3 The temple cover 14 is connected to the battery base cover 11 to seal the receiving slot 111. The temple cover 14 not only protects the battery assembly but also enhances the appearance of the temple 10. A snap-fit ​​connection, screw connection, or other methods can be used to ensure a secure connection between the temple cover 14 and the battery base cover 11. Furthermore, the temple cover 14 prevents dust and foreign matter from entering the receiving slot 111 and affecting the proper functioning of the battery. For example, dust and foreign matter entering the receiving slot 111 may cause the battery cell 12 to short-circuit, impacting the battery's performance and safety.

[0050] It can be seen that the battery base cover 11 has a dual role in the temple 10 of the present application. The battery base cover 11 not only serves as a part of the overall shell of the temple 10, and assumes the function of supporting and protecting other components inside the temple 10, but also can serve as one side of the battery shell, and together with the battery packaging cover 13, it constitutes a complete battery packaging structure. This makes full use of the limited space inside the temple 10. By integrating the battery base cover 11 with the battery shell function, the additional shell components in the traditional battery packaging structure are reduced, thereby maximizing the battery capacity within a limited space and effectively improving the battery life of the smart glasses 100. Compared with traditional designs, the temple 10 of the present application can provide more lasting power support for the smart glasses 100 without increasing the volume and weight of the temple 10, which greatly improves the user experience.

[0051] In some embodiments, the battery cell body 121 includes a diaphragm, a plurality of positive electrode sheets, and a plurality of negative electrode sheets, and the positive electrode sheets and the negative electrode sheets are stacked alternately. This arrangement can increase the contact area between the positive and negative electrodes and improve the charge and discharge efficiency of the battery. The diaphragm is arranged between adjacent positive and negative electrode sheets and covers the positive and negative electrode sheets. The diaphragm not only isolates the positive and negative electrodes, preventing the positive and negative electrodes from directly contacting and short-circuiting, but also provides a channel for the migration of carriers such as lithium ions during the charge and discharge process. At the same time, the diaphragm also covers the positive and negative electrode sheets, further enhancing the safety of the battery and preventing the battery from internal short-circuiting when subjected to external forces such as squeezing and puncture.

[0052] A plurality of positive electrodes are connected to the positive electrode ear 122, and a plurality of negative electrodes are connected to the negative electrode ear 123. A plurality of positive electrodes are connected to the positive electrode ear 122 by welding, crimping, etc., and a plurality of negative electrodes are connected to the negative electrode ear 123 in a similar manner. The positive electrode ear 122 and the negative electrode ear 123 serve as bridges connecting the battery cell 12 to the external circuit, and the quality and stability of their connection directly affect the performance of the battery. During the connection process, it is necessary to ensure that the contact resistance between the positive electrode ear 122 and the positive electrode sheet, and the negative electrode ear 123 and the negative electrode sheet is as small as possible to reduce energy loss at the connection. For example, high-quality connection joints can be obtained by using laser welding technology, which has the advantages of high connection strength and low resistance, and can effectively improve the charge and discharge efficiency and service life of the battery.

[0053] During battery operation, especially when the battery experiences abnormal conditions such as overcharging, over-discharging, or an internal short circuit, gas is generated inside the battery, causing the internal pressure to increase. To ensure the safety and stability of the battery, a vent 112 is provided on the battery base cover 11, which communicates with the interior of the battery shell. The position and size of the vent 112 are carefully designed to ensure that gas can be discharged promptly when the internal pressure of the battery is too high, while also preventing external impurities from entering the battery. For example, the size of the vent 112 cannot be too large, otherwise it may cause electrolyte leakage or external moisture to enter; nor can it be too small, otherwise it may affect the gas discharge rate and prevent the internal pressure of the battery from being released in a timely manner.

[0054] A one-way valve is provided at the exhaust hole 112 to prevent external air and moisture from entering the battery case, while allowing the gas generated inside the battery to be discharged when the pressure is too high.

[0055] A one-way valve is a valve device with a one-way flow function. It only allows gas to escape from the battery casing to the outside, while preventing external air and moisture from entering. This design has significant advantages. From a safety perspective, when the internal pressure of the battery is too high, the one-way valve can open in time to allow the gas to escape, preventing dangerous situations such as battery explosion caused by excessive internal pressure.

[0056] For example, under extreme operating conditions, such as high temperatures or when the battery is overcharged, a one-way valve can effectively release internal pressure, ensuring the safety of the battery and the user. From a battery performance perspective, a one-way valve also prevents external air and moisture from entering the battery casing. Oxygen and moisture in the air can chemically react with the electrolyte and electrode materials within the battery, degrading battery performance. For example, moisture can decompose the electrolyte, producing harmful gases that reduce the battery's charge and discharge efficiency and lifespan; oxygen can also oxidize the electrode materials, reducing their activity. By installing a one-way valve, external air and moisture can be effectively isolated, maintaining a stable and dry internal battery environment, thereby improving battery performance and reliability.

[0057] In some embodiments, see Figure 7 , Figure 7 A schematic diagram of the battery base cover structure provided by an embodiment of the present application. The receiving slot 111 is divided into a cell securing area 1111 and an electronic component securing area 1112. The electronic component securing area 1112 is provided to the side of the cell securing area 1111. The cell 12 and the battery packaging cover 13 are secured to the cell securing area 1111.

[0058] The battery cell fixing area 1111 refers to a specific area in the receiving groove 111 that is specifically used to fix the battery cell 12 and the battery packaging cover 13. The electronic component fixing area 1112 is an area in the receiving groove 111 that is arranged on the side of the battery cell fixing area 1111 and is used to fix electronic components. Electronic components may include speakers, circuit boards, sensors, connectors, etc. These components undertake important tasks such as data transmission, signal processing, and function control in devices such as smart glasses 100. The design of the electronic component fixing area 1112 needs to take into account factors such as the size, shape, heat dissipation requirements, and connection methods of the electronic components to ensure that the electronic components can work properly.

[0059] From the perspective of space utilization, placing the electronic component fixing area 1112 on the side of the battery fixing area 1111 can fully utilize the limited space inside the temple 10, avoiding interference between components and wasting space. The number of the electronic component fixing area 1112 is greater than or equal to one.

[0060] In the smart glasses 100, multiple electronic components need to work together to achieve its rich functions. Different electronic components have different functions and working requirements. In order to reasonably arrange these components, avoid electromagnetic interference, signal conflicts and other problems between them, and meet the needs of heat dissipation, connection and other aspects, it is necessary to set up multiple electronic component fixing areas 1112. For example, the speaker may require a relatively independent and spatially appropriate area to ensure the quality of sound output; the circuit board, as the core control component, needs to maintain an appropriate distance and connection method with other components to ensure the stability and accuracy of signal transmission; the sensor may need to select a suitable position for fixing according to its sensing direction and range. Therefore, setting up multiple electronic component fixing areas 1112 can better meet the installation and working requirements of different electronic components and improve the overall performance and reliability of the smart glasses 100.

[0061] For example, in terms of the shape of the temple 10, there are at least three electronic component fixing areas 1112, one of which is located at the end of the temple 10 close to the frame to place a circuit board or motherboard, and another electronic component fixing area 1112 is located at the end of the temple 10 away from the frame to place a charging port, such as a Pogo pin port, a Type-C port, etc.; and another electronic component fixing area 1112 is located on one side of the battery fixing area 1111 to place a speaker. This ergonomic design can enhance the audio experience of the smart glasses 100. By placing the speaker on one side of the battery fixing area 1111, when the user wears the smart glasses 100, the speaker can be located close to the human ear, allowing sound to enter the human ear more directly, reducing scattering and loss of sound during propagation, and improving sound clarity and quality.

[0062] This area division and layout approach allows for the simultaneous accommodation of the battery cell 12 and various electronic components within the limited space of the temple 10, achieving functional integration. When designing the space for the accommodation slot 111 in the temple 10, the electronic component securing area 1112 is first established, followed by the battery cell securing area 1111. Specifically, the position and layout of each electronic component within the temple 10 are determined based on the functional requirements of the smart glasses 100 and the characteristics of the electronic components, thereby demarcating the electronic component securing area 1112. Then, based on the remaining space and the shape adjustability of the battery cell 12, the battery cell securing area 1111 is designed and adjusted to maximize space utilization.

[0063] The battery cell 12 and the battery packaging cover 13 are fixed in the battery cell fixing area 1111. The battery cell fixing area 1111 has been specially designed and optimized to ensure that the battery cell 12 and the battery packaging cover 13 can be firmly installed therein. During the installation process, the battery cell 12 is accurately placed in the battery cell fixing area 1111, and then the battery cell 12 is firmly fixed by gluing, snapping, etc. The battery packaging cover 13 is tightly connected to the battery base cover 11 by welding, screw connection, etc., and together they form a closed battery shell to protect the battery cell 12. This fixing method can ensure that the battery cell 12 and the battery packaging cover 13 will not shake or displace during the use of the temple 10, thereby ensuring the stability and safety of the battery.

[0064] Among them, a thermal insulation layer is provided between the battery cell fixing area 1111 and the electronic component fixing area 1112 to reduce the impact of the heat generated by the battery cell 12 during operation on the electronic components. During operation, the battery cell 12 generates a large amount of heat due to the internal electrochemical reaction. If this heat cannot be dissipated in time or is transferred to the electronic components, it may cause the temperature of the electronic components to rise. Electronic components are generally sensitive to temperature, and excessively high temperatures will affect their performance and lifespan. For example, some integrated circuit chips may experience unstable operation, data transmission errors, and even burn out in a high-temperature environment. The provision of a thermal insulation layer can effectively reduce the transfer of heat generated by the battery cell 12 to the electronic components. The thermal insulation layer can be made of materials with good thermal insulation properties, such as aerogel felt, ceramic fiber paper, etc. These materials have low thermal conductivity and can effectively prevent heat conduction.

[0065] In some embodiments, the temple 10 further includes a speaker, which is disposed within the electronic component fixing area 1112. The speaker is an electroacoustic transducer that converts electrical signals into acoustic signals. In the temple 10 of the present application, the speaker serves as an audio output device for playing sounds, thereby realizing the audio playback function of the smart glasses 100, such as playing music, voice prompts, etc.

[0066] From the perspective of functional implementation, placing the speaker in the electronic component fixing area 1112 can fully utilize the space inside the temple 10 and achieve functional integration. In the smart glasses 100, the speaker plays an important role in audio output, such as playing music, voice navigation prompts, incoming call ringtones, etc. The electronic component fixing area 1112 provides a stable mounting position for the speaker, preventing the speaker from shaking or shifting during the use of the temple 10 and affecting the audio playback effect. For example, when the user is exercising or engaged in daily activities, the temple 10 will be subjected to various external forces. If the speaker is not firmly installed, problems such as sound distortion and noise may occur. By fixing the speaker in the electronic component fixing area 1112, through reasonable fixing methods such as screw fixing, glue bonding, etc., it can be ensured that the speaker always maintains a stable working state, providing the user with a clear, high-quality audio experience.

[0067] However, the speaker generates vibrations during operation. If this vibration is directly transmitted to the battery and the structure of the temple 10, it may cause a series of adverse effects. On the one hand, the vibration may cause the electrode material inside the battery to loosen, the electrolyte to leak, and other problems, thereby affecting the performance and life of the battery. For example, long-term vibration may increase the internal resistance of the battery, resulting in a decrease in the battery's charge and discharge efficiency and shortening the battery's service life. On the other hand, vibration may also cause the structure of the temple 10 to loosen or deform, affecting the overall stability and wearing comfort of the temple 10. To address this problem, a shock-absorbing pad is provided between the speaker and the battery base cover 11 to reduce the impact of the speaker vibration on the battery and the structure of the temple 10. The shock-absorbing pad is a layer of elastic material, such as rubber or silicone, arranged between the speaker and the battery base cover 11. These materials can effectively absorb and buffer the energy generated by the speaker vibration, reducing the transmission of vibration to the battery and the structure of the temple 10.

[0068] Please continue reading Figure 3 as well as Figure 4 In order to allow the sound emitted by the speaker to be smoothly transmitted to the outside of the temple 10, the battery base cover 11 is provided with a sound outlet 113, and the sound outlet 113 is arranged corresponding to the speaker. The sound outlet 113 is a hole arranged on the battery base cover 11 corresponding to the position of the speaker, which is used to guide the sound emitted by the speaker to the outside of the temple 10 so that the user can hear clear sound. For example, the position of the sound outlet 113 can be optimized according to the sound emission direction of the speaker and the user's wearing habits, so that the sound can be directly and clearly transmitted to the user's ears. At the same time, the size of the sound outlet 113 also needs to take into account the sound propagation efficiency and the structural strength of the temple 10. If the size of the sound outlet 113 is too small, it may cause obstruction of sound propagation and affect the sound quality; if the size is too large, it may reduce the structural strength of the temple 10 and affect the service life of the temple 10.

[0069] During actual use, the environment in which the temple 10 is located may contain pollutants such as dust and debris. If these pollutants enter the receiving groove 111 through the sound outlet hole 113, it may have an adverse effect on the speaker sound quality and battery performance. Dust and debris may adhere to the speaker's diaphragm, affecting the vibration of the diaphragm, thereby causing sound distortion, reduced volume and other problems. In addition, dust and debris may also enter the area where the battery is located, react with the electrolyte, or affect the heat dissipation of the battery, thereby reducing the performance and safety of the battery. To prevent this from happening, a dustproof net is provided at the sound outlet hole 113 to prevent dust and debris from entering the receiving groove 111 and affecting the speaker sound quality and battery performance. The dustproof net is usually made of a mesh material with a fine pore size, such as nylon mesh, metal mesh, etc. These materials can effectively block the entry of dust and debris, preventing dust and debris from having an adverse effect on the speaker sound quality and battery performance.

[0070] Please continue to see Figure 4 The battery cell body 121 includes a first battery cell segment 1211 and a second battery cell segment 1212, and the first battery cell segment 1211 is connected to the second battery cell segment 1212. The first battery cell segment 1211 is in close contact with the wall of the receiving groove 111. From the perspective of space utilization, by making the first battery cell segment 1211 closely contact with the wall, the gap between the battery cell 12 and the receiving groove 111 can be minimized, thereby fully utilizing the space inside the temple 10 and improving space utilization. For example, in some smart glasses 100 designs that have strict restrictions on the size of the temple 10, this compact layout can accommodate a larger capacity battery cell 12 without increasing the volume of the temple 10, providing more durable power support for the smart glasses 100. From the perspective of structural stability, the close fit between the first cell segment 1211 and the slot wall can enhance the fixation of the cell 12 within the slot 111, reducing displacement of the cell 12 due to shaking or vibration during use, and avoiding battery performance degradation or safety hazards caused by the position change of the cell 12. For example, when the user is engaged in strenuous exercise or is subjected to external impact, the tight fit design can ensure that the cell 12 remains in the correct position, ensuring the normal operation of the battery.

[0071] The outer side of the second battery cell segment 1212 and the battery base cover 11 are surrounded by an electronic component fixing area 1112. The electronic component fixing area 1112 provides an independent installation space for electronic components, avoiding mutual interference between the electronic components and the battery cells 12. For example, electronic components may generate electromagnetic radiation during operation, and the battery cells 12 also have certain requirements for the electromagnetic environment. Through this structural layout, the electromagnetic interference of electronic components on the battery cells 12 can be effectively reduced, ensuring the stable performance of the battery. In addition, this layout method also facilitates the connection and wiring between the electronic components and the battery cells 12.

Furthermore, the appropriate material selection can enhance the mechanical properties and corrosion resistance of the battery base cover 11, thereby extending the service life of the temple 10.

[0077] S2. Provide a battery cell 12 and set the battery cell 12 in the receiving groove 111. The battery cell 12 includes a battery cell body 121, a positive electrode ear 122 and a negative electrode ear 123. The positive electrode ear 122 and the negative electrode ear 123 protrude from the surface of the battery cell body 121. Accurately place the prepared battery cell 12 in the receiving groove 111 of the battery base cover 11. During the installation process, part of the structure of the battery cell 12 fits tightly with the groove wall of the receiving groove 111 to avoid shaking or displacement. The installation stability of the battery cell 12 can be ensured by designing a reasonable positioning structure and adopting appropriate fixing methods, such as snaps, glue bonding, etc. At the same time, the size and shape of the battery cell 12 can be optimized according to the shape of the receiving groove 111 to maximize the space utilization, so that the temple 10 can accommodate a larger capacity battery in a limited space.

[0078] S3. Provide a battery packaging cover 13. Place the battery packaging cover 13 over the battery cell body 121 and secure the battery packaging cover 13 to the battery base cover 11 to form a battery case. The positive and negative tabs 122 and 123 are exposed outside the battery case. The battery base cover 11 and / or the battery packaging cover 13 are made of steel, which has the advantages of high strength and good corrosion resistance, and can provide reliable protection for the battery.

[0079] S4. Inject electrolyte into the battery case. The electrolyte is the medium for ion transport in the battery. Its composition and properties have a significant impact on the battery's charge-discharge performance, cycle life, and other aspects. When injecting the electrolyte, the injection volume and speed must be strictly controlled to ensure that the electrolyte fully penetrates the battery cell body 121 while preventing electrolyte overflow.

[0080] Injecting the right amount of electrolyte ensures smooth ion transport within the battery, improving the battery's charge and discharge efficiency and performance. Precisely controlling the injection volume and speed can avoid battery performance issues caused by excessive or insufficient electrolyte, such as increased internal resistance and decreased capacity.

[0081] S5. Provide a temple cover 14 and connect the temple cover 14 to the battery base cover 11 to close the receiving groove 111.

[0082] The temple cover 14 not only protects the battery and internal electronic components but also serves as an integral part of the temple 10's exterior, integrating with other components such as the frame to complete the temple 10 structure. The connection of the temple cover 14 provides additional protection for the battery and internal electronic components, preventing them from being corroded and damaged by the external environment. Furthermore, a suitable connection ensures a tight seal and stability between the temple cover 14 and the battery base cover 11, enhancing the structural strength and reliability of the entire temple 10.

[0083] In some embodiments, before the battery packaging cover 13 is fixed to the battery base cover 11 , the method for preparing the temple 10 further includes vacuuming the interior of the battery shell to remove the internal air.

[0084] This step can effectively reduce the gas content inside the battery and reduce the safety hazards caused by gas expansion during battery use. It is also conducive to the uniform distribution of the electrolyte.

[0085] In some embodiments, the battery packaging cover plate 13 is fixed to the battery base cover 11. The method for preparing the temple 10 includes: fixing the battery packaging cover plate 13 to the battery base cover 11 by laser welding. Laser welding technology has the advantages of fast welding speed, high welding strength, and a small heat-affected zone. It can achieve a high-precision sealing connection between the battery base cover 11 and the battery packaging cover plate 13, thereby improving the sealing and structural strength of the battery shell.

[0086] During the laser welding process, infrared temperature measurement technology is used to monitor the temperature of the weld area in real time to ensure weld quality and prevent overheating from affecting battery performance. Laser welding offers advantages such as high welding speed, high weld strength, and a small heat-affected zone, ensuring the sealing and stability of the battery case. During the laser welding process, infrared temperature measurement technology is used to monitor the temperature of the weld area in real time. By precisely controlling the welding temperature, the adverse effects of overheating on battery performance, such as reduced electrode material activity and electrolyte decomposition, can be avoided, thereby ensuring weld quality.
