[0002] AR (Augmented Reality) glasses are near-eye display devices that overlay images generated by the device onto the real world.

Therefore, the emergence of AR glasses provides science explorers with a more convenient tool for exploration and is becoming more popular among the general public.

[0003] As AR glasses become more widely used, their shortcomings are becoming increasingly prominent, with short battery life being one of the most pressing issues to address.

[0066] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0067] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0068] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0069] The main solution of this application embodiment is: to propose an AR glasses, which includes a frame and a first temple assembly and a second temple assembly respectively connected to both ends of the frame; a built-in battery and a battery management module are disposed in the cavity enclosed by the first temple assembly, and the built-in battery is electrically connected to the battery management module; a battery module is disposed in the cavity enclosed by the second temple assembly, and the battery module is electrically connected to the battery management module; the battery management module is used to control the built-in battery to enter a discharge state when it detects that the battery module is in a non-dischargeable state, so as to provide power for the operation of the AR glasses; the battery management module is also used to control the battery module to enter a discharge state when it detects that the battery module is in a dischargeable state, so as to provide power for the operation of the AR glasses and / or provide charging power for the built-in battery.

[0070] As AR glasses become more widely used, their shortcomings are becoming increasingly prominent, with short battery life being one of the most pressing issues to address. When the battery in AR glasses is charging, it cannot provide power to the glasses, causing them to shut down. Frequent battery charging significantly reduces the overall battery life of AR glasses.

[0071] This application integrates a built-in battery and a battery management module within the cavity of the first temple assembly of AR glasses, and a battery module within the cavity of the second temple assembly. The built-in battery and the battery module are electrically connected to the battery management module. The battery management module detects and controls the charging and discharging operations of the built-in battery and the battery module. When the battery module is detected to be in a non-discharging state, the built-in battery is controlled to enter a discharging state to provide power for the operation of the AR glasses. This avoids the AR glasses entering a shutdown state and thus interrupting the battery life when the battery module cannot provide power. Conversely, when the battery module is detected to be in a discharging state, the battery module is controlled to enter a discharging state to provide power for the operation of the AR glasses and / or to charge the built-in battery. This achieves uninterrupted power supply for the operation of the AR glasses by switching between the built-in battery and the battery module, thereby extending the battery life of the AR glasses.

[0072] Based on this, the embodiments of this application provide AR glasses, referring to... Figure 1 , Figure 1 This is a schematic diagram of the AR glasses in this embodiment.

[0073] In this embodiment, the AR glasses include a frame 10 and a first temple assembly 20 and a second temple assembly 30 respectively connected to both ends of the frame 10; a built-in battery 201 and a battery management module 202 are provided in the cavity enclosed by the first temple assembly 20, and the built-in battery 201 is electrically connected to the battery management module 202; a battery module 301 is provided in the cavity enclosed by the second temple assembly 30, and the battery module 301 is electrically connected to the battery management module 202.

[0074] The battery management module 202 is used to control the built-in battery 201 to enter the discharge state when it is detected that the battery module 301 is in a non-dischargeable state, so as to provide power for the operation of the AR glasses; the battery management module 202 is also used to control the battery module 301 to enter the discharge state when it is detected that the battery module 301 is in a dischargeable state, so as to provide power for the operation of the AR glasses and / or provide charging power for the built-in battery 201.

[0075] First, the structure of the AR glasses proposed in this embodiment will be described, based on... Figure 1As can be seen, the AR glasses proposed in this application have two batteries: one is a built-in battery 201 integrated into the cavity enclosed by the first temple assembly 20, and the other is a battery module 301 integrated into the cavity enclosed by the second temple assembly 30. Specifically, the built-in battery 201 is located in the middle to rear section of the first temple assembly 20, for example... Figure 1 The position of the second temple assembly 30 is set in a way that avoids affecting the position of other components, and the cavity of the second temple assembly 30 is only used to house the battery module 301.

[0076] Meanwhile, a battery management module 202 is also set in the middle front section of the first temple assembly 20 to manage and control the charging and discharging status and charging and discharging safety of the built-in battery 201 and battery module 301. Therefore, the built-in battery 201 and battery module 301 need to establish a corresponding connection relationship with the battery management module 202. The battery management module 202 manages and controls the built-in battery 201 and battery module 301 according to the preset algorithm strategy set inside, and this management and control process is related to the structure of the AR glasses.

[0077] The AR glasses in this embodiment can be either integrated or detachable. Integrated glasses mean that the frame 10, first temple assembly 20, and second temple assembly 30 are a single, non-detachable unit. Therefore, the charging port of this type of AR glasses is the main interface of the AR glasses, and charging is performed by directly connecting a power cord to the charging power source through the main interface on the glasses. Detachable glasses, on the other hand, mean that the AR glasses can be easily disassembled. For example, in this embodiment, the second temple assembly 30 of the detachable AR glasses can be easily detached from the frame 10. Therefore, the charging port of this type of AR glasses can be the connection port of the second temple assembly 30 to the frame 10. Charging is performed by directly detaching the second temple assembly 30 from the frame 10 and then connecting it to the connection port on the second temple assembly 30 via an external power source.

[0078] The general management and control process is as follows:

[0079] ① When the battery management module 202 determines that the battery module 301 is in a non-discharge state (e.g., the internal energy stored in the battery module 301 is exhausted, or the second temple assembly 30 where the battery module 301 is located is detached from the frame 10) based on the calculated voltage value of the battery module 301 according to the preset algorithm strategy, it will directly switch the control of the built-in battery 201 to enter the discharge state when it detects that the AR glasses are in operation, so as to provide power for the operation of the AR glasses. This avoids the phenomenon of poor battery life and short battery life when the AR glasses directly enter the shutdown state when the battery module 301 cannot provide power to the AR glasses.

[0080] ② Based on a preset algorithm strategy and the calculated voltage value of the battery module 301, the battery management module 202 determines whether the battery module 301 is in a dischargeable state (e.g., the battery module 301 has sufficient internal energy, or the battery module 301 has been fully charged and reassembled onto the frame 10). When the AR glasses are detected to be in operation, the module 202 directly switches from power supply from the built-in battery 201 to power supply from the battery module 301. This means controlling the built-in battery 201 to exit the discharge state and simultaneously controlling the battery module 301 to enter the discharge state, providing power to the AR glasses. The module 202 then adjusts the power supply according to the built-in battery's voltage value. When the voltage value reflected by the electrical energy of the built-in battery 201 indicates insufficient internal power, the battery module 301 is controlled to provide charging power to the built-in battery 201. If the AR glasses are not detected to be running, but the voltage value reflected by the electrical energy of the built-in battery 201 indicates insufficient internal power, then only the battery module 301 needs to be controlled to provide charging power to the built-in battery 201. If the AR glasses are detected to be running, but insufficient internal power is not detected in the built-in battery 201, then only the battery module 301 needs to be controlled to provide power to the AR glasses. This balances and replenishes the internal power of the built-in battery 201, preventing insufficient internal power from causing the battery module 301 to be unable to discharge, thus forcing the AR glasses into a shutdown state and effectively extending the battery life of the AR glasses.

[0081] The specific structure and connection method of the built-in battery 201, battery management module 202, and battery module 301 are shown below:

[0082] In one feasible implementation, the battery management module 202 is connected to the built-in battery 201 in the following manner: Figure 2As shown. The battery management module 202 includes a first battery management unit for managing the built-in battery 201; the first battery management unit includes a first controller 2021, a first charging integrated circuit 2022, and a first battery integrated circuit 2023; the first controller 2021 establishes a bidirectional connection with the first charging integrated circuit 2022, and the first charging integrated circuit 2022 establishes a bidirectional connection with the first battery integrated circuit 2023; the built-in battery 201 is connected to the first control loop loop1 through the first connector A, and is electrically connected to the first charging integrated circuit 2022 or the first battery integrated circuit 2023 via the first control loop loop1.

[0083] Specifically, refer to Figure 2 As shown in the figure. If the built-in battery 201 and battery management module 202, which are integrated in the same first temple assembly 20, are not integrated on the same circuit board but are set separately, it means that the transmission distance between the built-in battery 201 and the battery management module 202 is relatively long. In order to avoid problems such as transmission attenuation or interference, the battery management module 202 needs to be equipped with a first battery management unit that performs battery management control on the built-in battery 201. As shown in the figure, the first battery management unit includes a first controller 2021, a first charging integrated circuit 2022 that establishes a bidirectional connection with the first controller 2021, and a first battery integrated circuit 2023 that establishes a bidirectional connection with the first charging integrated circuit 2022.

[0084] Among them, according to Figure 2 It can be seen that there are two connection methods between the built-in battery 201 and the components inside the first battery management unit. The first connection method is that after the built-in battery 201 is connected to the first control loop loop1 through the first connector A, a bidirectional connection relationship is established between the built-in battery 201 and the first charging integrated circuit 2022 through the first control loop loop1 (i.e., Figure 2 The second connection method involves the built-in battery 201 being connected to the first control loop loop 1 via the first connector A, and then establishing a bidirectional connection between the first control loop loop 1 and the first battery integrated circuit 2023 (i.e., ...). Figure 2 (marked by ② in the text).

[0085] The reason why the built-in battery 201 needs to be connected to the first control loop loop1 through the first connector A and then electrically connected to the first battery management unit through the first control loop loop1 is because the built-in battery 201 is not integrated on the circuit board integrated by the first battery management unit. It is necessary to ensure the power transmission effect through the first connector A and the first control loop loop1 to reduce the power attenuation caused by excessive transmission.

[0086] It should be noted that the first battery integrated circuit 2023 is responsible for monitoring the health status of the built-in battery 201. The first charging integrated circuit 2022, when the built-in battery 201 is discharging, is responsible for safely transferring the electrical energy from the built-in battery 201 to devices requiring power. When the built-in battery 201 is charging, it is responsible for safely transferring the electrical energy used to charge the built-in battery 201. Simultaneously, during the energy transfer process, it controls the voltage and current to ensure the safe charging of both the devices requiring power and the built-in battery 201. The first controller 2021 is responsible for coordinating the operation of the first charging integrated circuit 2022 and the first battery integrated circuit 2023, and providing preset algorithm strategies. For example, based on the electrical energy connected to the first charging integrated circuit 2022, it calculates the charging and discharging state, voltage, temperature, and current of the built-in battery 201. It is also responsible for battery protection of the built-in battery 201. For example, if the built-in battery 201 is found to be in an overcharged, over-discharged, or over-temperature state, the corresponding overcharge control information or over-discharge control information is sent to the first charging integrated circuit 2022. The first charging integrated circuit 2022 stops the charging and over-discharging operations of the built-in battery 201 according to the overcharge control information or over-discharge control information. The corresponding over-temperature control information is sent to the first battery integrated circuit 2023 via the first charging integrated circuit 2022. The first battery integrated circuit 2023 controls the temperature of the built-in battery 201 according to the over-temperature control information to ensure the safe operation and healthy state of the built-in battery 201.

[0087] The connection method between battery management module 202 and battery module 301 is as follows: Figure 3 and Figure 4 As shown.

[0088] The battery management module 202 includes a second battery management unit for managing the battery in the battery module 301. The specific structure of the second battery management unit is related to the structure type of the AR glasses.

[0089] When the AR glasses are integrated glasses, the second battery management unit in the AR glasses includes a second controller 2024, a second charging integrated circuit 2025, and a second battery integrated circuit 2026; the second controller 2024 and the second charging integrated circuit 2025 establish a bidirectional connection, and the second charging integrated circuit 2025 and the second battery integrated circuit 2026 establish a bidirectional connection; the battery module 301 is connected to the frame-integrated control loop loop2 through the second connector B, and is electrically connected to the second battery integrated circuit 2026 through the frame-integrated control loop loop2.

[0090] Specifically, refer to Figure 3As shown in the figure, because the battery module 301 and the battery management module 202 are not integrated into the same temple assembly, the transmission distance between the battery module 301 and the battery management module 202 is relatively long. To avoid problems such as transmission attenuation or interference, a second battery management unit is required in the battery management module 202 to manage and control the battery module 301. As shown in the figure, this second battery management unit includes a second controller 2024, a second charging integrated circuit 2025 bidirectionally connected to the second controller 2024, and a second battery integrated circuit 2026 bidirectionally connected to the second charging integrated circuit 2025.

[0091] The second battery integrated circuit 2026 is directly connected to the battery module 301 via the frame-integrated control loop 2. The second charging integrated circuit 2025 and the second controller 2024 are indirectly connected to the battery module 301 via the second battery integrated circuit 2026. The reason why the battery module 301 needs to be electrically connected to the second battery management unit via the frame-integrated control loop 2 is that the battery module 301 is not integrated on the circuit board integrated by the second battery management unit. The frame-integrated control loop 2 is needed to ensure the effectiveness of power transmission and reduce power attenuation due to excessive transmission distance.

[0092] It should be noted that the second battery integrated circuit 2026 is responsible for monitoring the health status of the battery module 301. The second charging integrated circuit 2025, when the battery module 301 is discharging, is responsible for safely transferring the electrical energy from the battery module 301 to devices requiring power. When the battery module 301 is charging, it is responsible for safely transferring the electrical energy used to charge the battery module 301. Simultaneously, during the energy transfer process, it controls the voltage and current to ensure the safe charging of both the devices requiring power and the battery module 301. The second controller 2024 is responsible for coordinating the operation of the second charging integrated circuit 2025 and the second battery integrated circuit 2026, and providing preset algorithm strategies. For example, based on the electrical energy connected to the second charging integrated circuit 2025, it calculates the charging and discharging state, voltage, temperature, and current of the battery module 301. It is also responsible for battery protection of the battery module 301. For example, if the calculated battery module 301 is in an overcharged, over-discharged, or over-temperature state, it sends the corresponding overcharge control information or over-discharge control information to the second charging integrated circuit 2025. The second charging integrated circuit 2025 stops the charging and over-discharging operations of the battery module 301 according to the overcharge control information or over-discharge control information. The corresponding over-temperature control information is sent to the second battery integrated circuit 2026 via the second charging integrated circuit 2025. The second battery integrated circuit 2026 controls the temperature of the battery module 301 according to the over-temperature control information to ensure the safe operation and healthy state of the battery module 301.

[0093] Specifically, refer to Figure 4 As shown, when the AR glasses are detachable glasses, the second battery management unit also includes a power replenishment subunit 2027 that establishes a bidirectional connection with the second controller 2024; the power replenishment subunit 2027 is connected to the first connector A through the first control loop loop1, and is electrically connected to the built-in battery 201 through the first connector A, while the battery module 301 in this structure is connected to the frame built-in control loop loop2 through the second connector B, and is electrically connected to the second charging integrated circuit 2025 through the frame built-in control loop loop2.

[0094] When the AR glasses are detachable, they are charged via the second temple assembly 30. This differs from the charging method of integrated glasses. Integrated glasses connect to the power source via a main interface, allowing the power to be directly stored in the built-in battery 201 and battery module 301. Detachable glasses, however, charge via the battery module 301 within the second temple assembly 30, meaning the power is not directly stored in the built-in battery 201. Therefore, to ensure sufficient power within the built-in battery 201 to support the AR glasses' operation, a power replenishment subunit 2027 is required in the second battery management unit of this structure. Unit 2027 is responsible for replenishing the built-in battery 201. The second controller 2024 establishes a connection with the first controller 2021. The first controller 2021 detects the power of the built-in battery 201 based on the first battery integrated circuit 2023. When it detects that the internal power of the built-in battery 201 is insufficient based on the voltage value reflected by the power of the built-in battery 201, it transmits the battery information of insufficient internal power of the built-in battery 201 to the second controller 2024. The second controller 2024 obtains the power of the battery module 301 connected to the second charging integrated circuit 2025 based on the battery information, and transmits the power to the built-in battery 201 through the replenishment subunit 2027, thereby replenishing and charging the built-in battery 201.

[0095] The reason why the battery module 301 needs to be connected to the frame-in-built control loop 2 through the second connector B, and then electrically connected to the second battery management unit through the frame-in-built control loop 2, is because the battery module 301 is not integrated on the circuit board integrated by the second battery management unit, and there is a connection port between the second temple assembly 30 and the frame 10. The second connector B and the frame-in-built control loop 2 are needed to ensure the power transmission effect and reduce the power attenuation caused by excessive transmission.

[0096] In another feasible implementation, the structure and connection method of the battery management module 202 and the built-in battery 201 are as follows: Figure 5 and Figure 6 As shown. The built-in battery 201 and the battery management module 202 are integrated on the same motherboard. The battery management module 202 includes a battery management unit for battery management of the built-in battery 201 and the battery module 301.

[0097] Reference Figure 5 As shown, when the AR glasses are integrated glasses, the battery management unit includes a controller 2028, a charging integrated circuit 2029, and a battery integrated circuit 2030; the controller 2028 establishes a bidirectional connection with the charging integrated circuit 2029, and the charging integrated circuit 2029 establishes a bidirectional connection with the battery integrated circuit 2030; the built-in battery 201 is electrically connected to the charging integrated circuit 2029 or the battery integrated circuit 2030 through the first connector A.

[0098] In this embodiment, the AR glasses are integrated into a single unit, and the built-in battery 201 and battery management module 202 in the same first temple assembly 20 are integrated on the same circuit board. This means that when the AR glasses are charging, the charging power can be directly stored in the built-in battery 201 and battery module 301. Since the built-in battery 201 and battery management module 202 are physically closely connected with a short transmission distance, there are no issues of transmission attenuation or interference. Therefore, only one battery management unit is needed in the battery management module 202 to manage and control the battery status of both the built-in battery 201 and battery module 301. This allows for monitoring and controlling the battery status of both batteries through a single battery management unit, achieving effective battery management and control while reducing device costs to some extent. As shown in the figure, the battery management unit includes a controller 2028, a charging integrated circuit 2029 bidirectionally connected to the controller 2028, and a battery integrated circuit 2030 bidirectionally connected to the charging integrated circuit 2029.

[0099] The built-in battery 201 can establish a connection with the charging integrated circuit 2029 via the first connector A (i.e., Figure 5 and Figure 6 The reference numeral ① can also establish a connection with the battery integrated circuit 2030 via the first connector A (i.e., Figure 5 and Figure 6 (Ref. ②) The controller 2028 establishes an indirect connection with the built-in battery 201 through the charging integrated circuit 2029 or the battery integrated circuit 2030.

[0100] The structure and connection method of battery management module 202 and battery module 301 are as follows: Figure 5As shown. The battery module 301 is connected to the frame's built-in control loop loop2 via a connecting wire, and is electrically connected to the battery integrated circuit 2030 via the frame's built-in control loop loop2.

[0101] Because the battery module 301 and the battery management module 202 are integrated into different temple assemblies and cannot be integrated onto the same circuit board, the battery module 301 still needs to establish a connection with the battery management module 202 through connecting wires and control circuits. Figure 5 As shown, specifically: the battery integrated circuit 2030 is connected to the battery module 301 via the built-in control loop loop2 of the eyeglass frame, and the charging integrated circuit 2029 and the controller 2028 are connected to the battery module 301 indirectly through the battery integrated circuit 2030.

[0102] The battery integrated circuit 2030 is responsible for monitoring the health status of the built-in battery 201 and the battery module 301. The charging integrated circuit 2029, when the built-in battery 201 or battery module 301 is discharging, is responsible for safely transferring the electrical energy from the built-in battery 201 or battery module 301 to devices requiring power. When the battery module 301 is charging, it is responsible for safely transferring the electrical energy used to charge the battery module 301 to the built-in battery 201 or battery module 301. Simultaneously, during the energy transfer process, it controls the voltage and current to ensure the safe charging of devices requiring power, the built-in battery 201, or the battery module 301. The controller 2028 is responsible for coordinating the operation of the charging integrated circuit 2029 and the battery integrated circuit 2030, and providing preset algorithm strategies. For example, based on the electrical energy connected to the charging integrated circuit 2029, it calculates the charging and discharging state, voltage, temperature, and current of the built-in battery 201 and the battery module 301. It is also responsible for battery protection of the built-in battery 201 and the battery module 301. For example, if the built-in battery 201 or the battery module 301 is found to be in an overcharged, over-discharged, or over-temperature state, the corresponding overcharge control information or over-discharge control information is sent to the charging integrated circuit 2029. The charging integrated circuit 2029 stops the charging or over-discharging operation of the built-in battery 201 or the battery module 301 according to the overcharge control information or over-discharge control information. The corresponding over-temperature control information is sent to the battery integrated circuit 2030 via the charging integrated circuit 2029. The battery integrated circuit 2030 controls the temperature of the built-in battery 201 or the battery module 301 according to the over-temperature control information to ensure the safe operation and healthy state of the built-in battery 201 and the battery module 301.

[0103] Reference Figure 6As shown, when the AR glasses are detachable glasses, the battery management unit also includes a power replenishment subunit 2027 that establishes a bidirectional connection with the controller 2028; the built-in battery 201 is electrically connected to the power replenishment subunit 2027 through the first connector A; the battery module 301 is connected to the frame-in-built control loop loop2 through the second connector B, and is electrically connected to the charging integrated circuit 2029 through the frame-in-built control loop loop2.

[0104] When the AR glasses are detachable, they are charged via the second temple assembly 30. Therefore, to ensure that the built-in battery 201 has sufficient power to support the operation of the AR glasses, a power replenishment subunit 2027 needs to be set in the battery management unit of this structure. This power replenishment subunit 2027 is responsible for replenishing the built-in battery 201. The controller 2028 detects the power of the built-in battery 201 based on the battery integrated circuit 2030. When it detects that the internal power of the built-in battery 201 is insufficient based on the voltage value reflected by the power of the built-in battery 201, the controller 2028 obtains the power of the battery module 301 connected to the charging integrated circuit 2029 based on the battery information and transmits the power to the built-in battery 201 through the power replenishment subunit 2027, thereby replenishing and charging the built-in battery 201.

[0105] The reason why the battery module 301 needs to be connected to the frame-in-built control loop 2 through the second connector B, and then electrically connected to the second battery management unit through the frame-in-built control loop 2, is because the battery module 301 is not integrated on the circuit board integrated by the second battery management unit, and there is a connection port between the second temple assembly 30 and the frame 10. The second connector B and the frame-in-built control loop 2 are needed to ensure the power transmission effect and reduce the power attenuation caused by excessive transmission.

[0106] In one feasible implementation, the built-in battery 201 provided in this application is a high-energy-density battery, such as... Figure 7 As shown, a single battery cell is wrapped with tape to protect it, while the positive terminal connection of the first connector A (i.e., Figure 7 The number ① in the diagram and the negative terminal connection (i.e.) Figure 7(2) The nickel plate 40 connects to the positive and negative terminals of the battery cell. Compared with conventional batteries, this high-energy-density battery has a higher energy density, providing a more stable and longer-lasting power supply. At the same time, it avoids the situation where increasing the battery size to extend the power supply time of conventional built-in batteries would require occupying too much structural space in the first temple assembly 20. It maximizes the utilization of the cavity of the first temple assembly 20, avoiding the situation where the battery size increases, occupying space or causing space congestion, which would enhance interference between devices.

[0107] The battery module 301 can be divided into various structures. This application proposes two possible structures for the battery module 301.

[0108] Reference Figure 8 As shown, in one feasible embodiment, the battery module 301 has an integrated battery structure; the battery module 301 includes a single battery cell composed of a cell stack 3011 and a protective shell 3012, and a battery protection module 50 located on the side of the single battery cell; the battery module 301 is integrated in the cavity of the second temple assembly 30, and the side with the battery protection module 50 is close to the connection between the second temple assembly 30 and the frame 10.

[0109] Among them, by Figure 8 As can be seen, the cell stack 3011 refers to multiple cells 3013 (such as lithium-ion cells) stacked together in series or parallel to form the required voltage and capacity. The protective shell 3012 refers to the shell used to encapsulate and protect these cell stacks 3011. It is usually made of plastic or other materials to prevent the cells 3013 from being affected by the external environment, such as physical impact, moisture or overheating.

[0110] To ensure the safety of the individual battery cell and prevent it from malfunctioning under abnormal conditions, a battery protection module 50 is installed on one side of the individual battery cell to ensure its safety and reliability during use. It should be noted that the side where the battery protection module 50 is installed is typically near the connection point between the second temple assembly 30 and the frame 10. This is because when the battery module 301 is discharging, it transmits electrical energy to the battery management module 202 located in the first temple assembly 20. The transmission direction is second temple assembly 30 → frame 10 → first temple assembly 20. Therefore, placing the battery protection module 50 on the side of the individual battery cell near the connection point between the second temple assembly 30 and the frame 10, i.e., at the interaction point between the battery module 301 and the frame 10, allows for effective detection of the electrical energy transmitted to the battery management module 202 without extending the transmission path.

[0111] Reference Figure 9As shown, in another feasible embodiment, the battery module 301 has a multi-cell parallel battery structure; the battery module 301 is a single cell formed by connecting multiple cells 3013, and a battery protection module 50 located on the side of the single cell; the battery module 301 is integrated in the cavity of the second temple assembly 30, and the side with the battery protection module 50 is close to the connection between the second temple assembly 30 and the frame 10.

[0112] by Figure 9 For example, suppose the battery module 301 in this embodiment is a single cell formed by two cells 3013 connected in parallel. The positive terminals of the two cells 3013 can be connected by copper wire or other conductive materials to form a parallel connection structure, or directly connected by a cell 3013 connector to form a single cell with a parallel structure.

[0113] Similarly, consistent with the above embodiments, in order to ensure the safety of the individual battery cells in this embodiment and prevent the risk of use caused by abnormal conditions of the individual battery cells, a battery protection module 50 is also provided on the side of the individual battery cell near the connection between the second temple assembly 30 and the frame 10. Its function will not be repeated here.

[0114] In one feasible implementation, refer to Figure 10 As shown, the battery protection module 50 includes a cell protection unit 501 and a charge / discharge protection unit 502; the cell protection unit 501 is disposed between the individual cell and the charge / discharge protection unit 502.

[0115] The battery protection module 50 in this embodiment also includes a battery management module 202, which can achieve three levels of safety protection for individual battery cells. Specifically: the first level of safety protection is implemented by the battery management module 202, which is responsible for system-level control of the battery's charge / discharge rate, temperature, SOC (System on Chip), and short circuit, ensuring that individual battery cells can safely and effectively perform charge and discharge operations; the second level of safety protection is implemented by the charge / discharge protection unit 502, which is used to protect the battery module 301 located on the second temple assembly from overcharge, over-discharge, overcurrent, and short circuit; the third level of safety protection is implemented by the cell-level protection unit 501, which is used to provide overcurrent protection for individual battery cells 3013. In this way, the battery protection module 50 achieves rapid battery protection, while the cell-level protection unit 501 and the charge / discharge protection unit 502 can avoid situations where protection is not timely due to the battery management module 202 being too far away.

[0116] Specifically, refer to Figure 11As shown, the frame 10 is provided with a first connection port 1, and the second temple assembly 30 is provided with a second connection port 2 on one side. The first connection port 1 and the second connection port 2 are fitted together.

[0117] As shown in the figure, the first connection port 1 on the frame 10 is a socket, and the second connection port 2 on the second temple assembly 30 is a pin. The first connection port 1 is used to insert and fix the second connection port 2, so as to realize the convenient disassembly of the battery module 301.

[0118] Furthermore, referring to Figure 12 As shown, a connection module is provided on the first connection port 1. The battery module 301 is electrically connected to the connection module via the second connector B, and is electrically connected to the third connector of the battery management module 202 via the connection module. The connection module contains pins for the frame-integrated control loop 2 (i.e., Figure 12 (port3 in the middle).

[0119] In this embodiment, a connection module is provided on the first connection port 1. As shown in the figure, the connection module has pins for the frame-integrated control loop loop 2. When the first connection port 1 and the second connection port 2 are engaged, the second connector B connected to the battery module 301 can be led out from the second connection port 2 and inserted into the connection module at the first connection port 1. This allows the second connector B to connect with the pins of the frame-integrated control loop loop 2 provided in the connection module. Since the other pin of the frame-integrated control loop loop 2 is connected to the third connector of the battery management module 202, the battery module 301 can be electrically connected to the battery management module 202 at this time, thereby providing power for the operation of the AR glasses and charging power for the built-in battery 201.

[0120] The above description is only a part of the embodiments of this application and does not limit the patent scope of this application. All equivalent structural transformations made under the technical concept of this application and using the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this application.
