Description

Technical Field

[0001] The embodiments disclosed herein relate to the fields of optical modules and head-mounted display devices, and more specifically to optical module adapters for use in head-mounted display devices. Background Technology

[0002] In PWG (Pancake Window Grating) head-mounted display devices (such as smart glasses and head-mounted display terminals), especially in scenarios where multiple people share a head-mounted display device in a home, head-mounted displays have become increasingly popular with the public due to technological advancements. However, traditional head-mounted displays with detachable lenses suffer from cumbersome installation, easy loosening, and damage to the optical engine after repeated disassembly. In home settings with multiple users, this approach cannot meet the needs of users with different prescriptions, nor can it easily adjust lens power. Therefore, there is a need for an optical module adapter that allows for quick disassembly and assembly of myopia lenses and optical modules, ensuring the position and stability of the lenses after installation, and preventing damage to the optical engine after repeated disassembly and assembly. Currently, traditional optical module adapters mostly rely on screws and clips, which are cumbersome to install and prone to loosening.

[0003] However, in practice, the following technical problems often arise when using traditional optical module adapters: Traditional detachable lenses rely heavily on mechanical fastening structures using screws and clips, resulting in cumbersome and time-consuming disassembly and assembly processes. This leads to inefficiency when users replace lenses and excessively long waiting times when multiple people share the device. Furthermore, traditional optical modules often use fixed lenses with non-adjustable prescriptions, failing to meet the needs of users with different vision types. This forces nearsighted users to wear additional eyeglasses when using head-mounted displays, causing discomfort and obstruction of the periphery of their field of vision. Additionally, in traditional technologies, lens disassembly and assembly require direct contact with the optical area or outer casing of the optical engine, and the fastening structure lacks protective design. Repeated disassembly and assembly can cause scratches to the optical engine by lens edges or tools, leading to damage, decreased optical performance, and a shortened lifespan.

[0020] The various embodiments of this disclosure have the following beneficial effects: An optical module adapter device for a head-mounted display device, as provided in some embodiments of this disclosure, allows for rapid disassembly, improving the replacement efficiency of the optical module adapter device and simplifying the assembly / disassembly process. It can meet different visual needs, thereby reducing the discomfort experienced by users wearing traditional eyeglasses, improving user experience, and reducing the risk of damage caused by contact with optical equipment. Specifically, the reasons for the numerous technical problems with existing optical module adapters are as follows: Traditional detachable lenses rely heavily on mechanical fixing structures with screws and clips, resulting in cumbersome and time-consuming disassembly and assembly processes. This leads to inefficiency when users replace lenses and excessively long waiting times when multiple people share the device. Furthermore, traditional optical modules mostly use fixed lenses with non-adjustable prescriptions, failing to meet the needs of users with different vision types. This forces nearsighted users to wear additional eyeglasses when using head-mounted display devices, causing discomfort and obstruction of the periphery of their field of vision. Finally, in traditional technologies, lens disassembly and assembly require direct contact with the optical area or outer shell of the optical engine, and the fixing structure lacks protective design.

The adapter lens is fixed to the bearing surface of the positioning base via the fixing member. The adapter lens and the fixing member form an integrated adapter structure, which is connected to the optomechanical device. Because the positioning base of the optical module adapter is fixedly engaged with the optomechanical device, the optical module adapter can quickly remove the lens, improving the replacement efficiency and simplifying the assembly / disassembly process. Furthermore, because the adapter lens is fixed via the fixing member, it can meet different visual needs, thereby reducing the discomfort experienced by users wearing traditional eyeglasses and improving the user experience. Because the above-mentioned adapter lens and the above-mentioned fastener form an integrated adapter structure and are then connected to the above-mentioned optical and mechanical equipment, the prescription can be changed simply by disassembling and assembling the lens itself, which can reduce the possibility of damage caused by contact with the optical and mechanical equipment.

[0034] Figure 6 This is an exploded structural diagram of the magnetic assemblies of the optical module adapter and the optomechanical equipment according to some embodiments of this disclosure. Figure 6 It may include a positioning base 1, a magnetic component 2, a connecting structure 3, an adapter lens 4, a metal frame 5, and an optomechanical device 6.

[0035] In some embodiments, such as Figure 1 As shown, the aforementioned optical module adapter may include a positioning base 1, a fixing member, and an adapter lens 4. The positioning base 1 is used to fix the positions of the optomechanical device 6 and the adapter lens 4. The fixing member is used to fix the adapter lens 4, facilitating positional fixation between it and the optomechanical device 6. The adapter lens 4 may be a functional component catering to different user vision needs. For example, the adapter lens 4 may be a myopia lens. The positioning base 1 may be a U-shaped frame.

[0036] In some embodiments, the above, as Figure 1As shown, the connection structure 3 of the positioning base 1 can be fixed in place with the pre-set adapter structure of the optomechanical device 6. This locking and fixing mechanism allows for quick disassembly of the lens, simplifying the replacement of the adapter lens 4.

[0037] In some embodiments, such as Figure 4 The adapter lens 4 shown above can be fixed to the bearing surface of the positioning base 1 by the aforementioned fastener. The bearing surface can be used to directly contact the adapter lens 4 to support it.

[0038] In some embodiments, the adapter lens 4 can form an integrated adapter structure with the fixing member. This integrated adapter structure can be connected to the optomechanical device 6. By connecting the integrated adapter structure to the optomechanical device 6, only the integrated adapter structure needs to be replaced when replacing the adapter lens 4, thus reducing the risk of damage to the optomechanical device 6 during the replacement process.

[0039] Optionally, when the aforementioned fastener is in a first preset state, the first preset state indicates that the fastener can be an elastic nylon filament 7. The elastic nylon filament 7 can be disposed on the positioning base 1. The elastic nylon filament 7 can fix the adapter lens 4 to form a first assembly by elastic clamping force. The elastic nylon filament 7 can be a synthetic fiber material with high elasticity and resilience. For example, the elastic nylon filament 7 can be nylon elastic yarn. The elastic clamping force is the elastic force generated by the elastic nylon filament 7 itself after being stretched. The first assembly can be fixed to the optomechanical device 6 by clamping it onto the positioning base 1.

[0040] Optionally, when the aforementioned fastener is in a second preset state, the second preset state indicates that the fastener can be a magnetic attraction component 2. The magnetic attraction component 2 includes at least one magnet, and the magnets in the at least one magnet can be evenly distributed on the bearing surface of the positioning base 1. The magnetic attraction component 2 can be a magnet with magnetic properties. The at least one magnet indicates that the number of magnetic attraction components 2 is at least one. It should be noted that the number of magnetic attraction components 2 is not specifically limited here and can be adjusted according to actual needs. For example, the number of magnetic attraction components can be two. The magnetic attraction components 2 are evenly distributed on the bearing surface of the positioning base 1 and can be used to provide a uniform magnetic attraction force to the positioning base 1 to fix the metal frame 5.

[0041] Optionally, the aforementioned optical module adapter may further include a metal frame 5. The metal frame 5 can be fixedly connected to the adapter lens 4 to form a second assembly. After the metal frame 5 is attracted and fixed to the magnetic component 2, the outer edge of the second assembly can be flush with the edge of the positioning base 1. The metal frame 5 can be a U-shaped frame for clamping and fixing the adapter lens 4. The flushness of the outer edge of the second assembly with the edge of the positioning base 1 better secures the second assembly to the positioning base 1. The metal frame 5 can be made of a material that can be attracted by the magnetic force of the magnetic component 2. For example, the metal frame 5 can be made of an iron-nickel alloy.

[0042] Optionally, the shape of the adapter lens 4 can match the external surface shape of the optomechanical device 6. The gap between the adapter lens 4 and the positioning base 1 can be smaller than a first preset gap. When the optical module adapter and the adapter lens 4 are connected, the optical center of the adapter lens 4 and the optical center of the optomechanical device 6 can be located on the same axis. Matching the shape of the adapter lens 4 with the shape of the optomechanical device 6 allows the adapter lens 4 to align with the edge of the optomechanical device after assembly with the positioning base 1. This, combined with the limiting position of the positioning base 1, further restricts the displacement of the adapter lens 4 (reducing lateral and longitudinal offsets) to improve installation position accuracy. A gap smaller than the first preset gap reduces the possibility of movement of the adapter lens 4. For example, the first preset gap can be 0.1 mm. Having the optical center of the adapter lens 4 and the optical center of the optomechanical device 6 on the same axis reduces the possibility of optical path offset transmission.

[0043] Optionally, the connecting structure 3 can be disposed in the non-optical area of ​​the positioning base 1. The preset adapter structure of the optomechanical device is a recess, and the connecting structure 3 is a protrusion. The non-optical area refers to the area of ​​the positioning base 1 where the adapter lens 4 is not installed. The recess can be a groove adapted to the shape of the protrusion, and the protrusion can be fitted into the recess. It should be noted that the types of the adapter structure and the connecting structure 3 are not specifically limited here and can be adjusted according to actual needs.

[0044] Optionally, the positioning base 1 can be a ring structure, and the gap between the positioning base 1 and the optomechanical device 6 is smaller than the second preset gap. The positioning base 1 can be a ring structure to conform to the shape of the adapter lens 4. Having a gap between the positioning base 1 and the optomechanical device 6 smaller than the second preset gap can reduce the possibility of the optomechanical device 6 not being securely installed. For example, the second preset gap can be 0.05 mm.

[0045] Optionally, both ends of the aforementioned elastic nylon thread 7 can be detachably connected to the bearing surface of the positioning base 1. Wherein, both ends of the aforementioned elastic nylon thread 7 are detachably disposed on the bearing surface of the positioning base 1, and the two ends of the aforementioned elastic nylon thread 7 are fixedly disposed during operation. For example, the connection method between the two ends of the aforementioned elastic nylon thread 7 and the bearing surface of the positioning base 1 can be a miniature elastic snap-fit ​​type.

[0046] Optionally, the magnetic attraction force for the metal frame 5 and the magnetic component 2 to be engaged and fixed can be greater than a preset magnetic attraction force. The preset magnetic attraction force represents the magnetic attraction force inherent in the magnetic component 2 itself. A magnetic attraction force greater than the preset magnetic attraction force allows the metal frame 5 to be more firmly fixed to the positioning base 1. It should be noted that the value of the preset magnetic attraction force is not specifically limited here and can be adjusted according to actual needs. For example, the preset magnetic attraction force can be 5N.

[0047] In addressing the aforementioned technical problems in the process of adopting a technical solution, considering the application scenario: when using head-mounted display devices for teaching in schools (such as in school laboratories), different students require different lenses. Students' breathing moisture causes the lenses to fog up, often accompanied by the following technical problem two: traditional optical module adapters for head-mounted display devices lack multi-specification adaptation solutions, limiting their compatibility to single-diameter optical module lenses. They cannot flexibly adjust the adapter structure according to the lens size of different devices, resulting in a limited range of compatibility. Users cannot adapt to different modules when using different sizes of head-mounted display devices. Furthermore, current optical module adapters for head-mounted display devices lack anti-fogging functionality, causing moisture to easily condense on the lens surface due to internal and external temperature differences. External moisture can easily penetrate directly, and internal moisture cannot be expelled in time, leading to lens fogging, obstructing vision, and reducing display clarity and visual experience. To meet the following requirements for this application scenario: adaptability to multiple lens specifications and reduction of lens fogging, we decided to adopt the following solution: Optionally, the positioning base may also be provided with a telescopic structure. The telescopic structure may include an outer fixing ring and an inner telescopic ring, with the outer curved surface of the outer fixing ring fixedly disposed on the positioning base. The inner telescopic ring may be disposed inside the outer fixing ring, and at least one elastic telescopic member connects the inner telescopic ring and the outer fixing ring. The elastic telescopic member can drive the inner telescopic ring to extend and retract radially to adapt to optical module lenses of different diameters. The adapting lens may be disposed inside the inner telescopic ring. The sidewall of the positioning base may have at least one micro-convection hole, which is uniformly distributed, with a diameter ranging from 0.1 mm to 0.3 mm. The ratio of the total cross-sectional area of ​​the micro-convection holes to the volume of the internal gas cavity of the optical module adapting device is greater than 15:10000. A waterproof and breathable membrane is provided on the inner side of the aforementioned micro-convection holes, and the pore size of the membrane ranges from 0.01μm to 0.1μm. The opening direction of the aforementioned micro-convection holes can form an angle of 30° to 45° with the aforementioned optomechanical equipment. A shallow air guide groove is also provided at the micro-convection holes on the side of the positioning base facing the aforementioned adapter lens. The connection between the aforementioned outer fixing ring and the aforementioned positioning base can be an embedded snap-fit ​​connection. The aforementioned inner telescopic ring can be snapped onto the inner side of the aforementioned outer fixing ring. The aforementioned elastic telescopic member can drive the telescopic movement of the aforementioned inner telescopic ring to adjust for adapter lenses of different sizes. For example, the elastic telescopic member can be a radial compression spring. The aforementioned micro-convection holes can realize rapid gas exchange between the internal gas cavity of the adapter device and the outside environment. The pore size range of the aforementioned micro-convection holes can increase the gas flow rate and quickly expel internal moisture. The volume of the aforementioned internal gas cavity can be the volume of the space between the aforementioned optomechanical equipment and the aforementioned adapter lens. The ratio of the total cross-sectional area of ​​the aforementioned micro-convection holes to the volume of the internal gas cavity of the aforementioned optical module adapter allows for doubling the gas exchange rate, rapidly expelling internal moisture and introducing ambient temperature gas, preventing moisture from condensing into fog within the cavity. The aforementioned waterproof and breathable membrane can be a membrane that blocks liquid water vapor (such as student sweat) and reduces direct contact between liquid water vapor and the lens, preventing fogging. For example, the waterproof and breathable membrane can be a polytetrafluoroethylene microporous waterproof and breathable membrane. The pore size range of the aforementioned waterproof and breathable membrane allows gas to pass through freely for gas exchange, while liquid water cannot pass through. The angle range between the aforementioned opening direction and the aforementioned optomechanical equipment optimizes the anti-fogging effect. The aforementioned shallow air guide channel guides the inclined airflow entering through the micro-convection holes to various corners of the cavity, reducing localized airflow accumulation or the formation of dead zones.

[0048] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "when users use head-mounted display devices of different specifications, they cannot adapt to different modules; the lens fogs up, obstructing the view and reducing display clarity and visual experience." The reasons for the inability to adapt to different lens specifications and the reduction in display clarity and visual experience are as follows: When head-mounted display devices are used for teaching in schools (such as in school laboratories), traditional optical module adapters for head-mounted display devices do not have multiple specification adaptation solutions, resulting in them only being able to specifically match optical module lenses of a single diameter specification. They cannot flexibly adjust the adaptation structure according to the lens size of different devices, resulting in a limited adaptation range. When users use head-mounted display devices of different specifications, they cannot adapt to different modules. Because the optical module adapters currently used in head-mounted display devices lack anti-fogging functions, water vapor easily condenses on the lens surface due to the temperature difference between the inside and outside, and external water vapor can easily penetrate directly, while internal moisture cannot be discharged in time, resulting in lens fogging, obstructing the view, and reducing display clarity and visual experience. If the above factors are resolved, it is possible to adapt to lenses of various sizes and reduce lens fogging. To achieve this effect, some embodiments of this disclosure can adapt to lenses of different sizes using the aforementioned telescopic ring, and can also defogging the lenses using the aforementioned micro-convection holes and shallow air channels to improve display clarity and visual experience.

[0049] In addressing the aforementioned technical problems in the application scenario—specifically, when using head-mounted display devices for teaching in schools (e.g., in school laboratories)—students are often unfamiliar with the specific configuration methods of these devices, leading to the following technical problem: Traditional head-mounted display devices lack the function of automatically generating alignment adjustments based on the optical center. This means that relying solely on manual adjustment by the user cannot capture the coaxial offset of the optical center after lens assembly, resulting in easy optical center misalignment after lens installation. This, in turn, causes blurred images, affecting visual clarity and immersion. Considering the following requirements for this application scenario: optical center offset calibration and adaptability to low-threshold configurations, we decided to adopt the following solution: Optionally, the aforementioned optical module adapter may further include a photoelectric alignment sensor, a laser coaxial detector, and a drive component that are communicatively connected to the processor. The processor can be an instrument that processes various types of information. For example, the processor can be a central processing unit (CPU). It should be noted that the communication connection may include, but is not limited to, 3G / 4G connections, WiFi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultra-wideband) connections, and other currently known or future-developed communication methods. The photoelectric alignment sensor can be a sensor that collects key state data such as the radial position value and circumferential angle value of the adapter lens. For example, the photoelectric alignment sensor can be a miniature photoelectric displacement sensor. The laser coaxial detector can be a sensor that collects the coaxial state value and axial state value of the optical center of the adapter lens and the optomechanical equipment. For example, the laser coaxial detector can be a miniature laser coaxiality sensor. The drive component can drive the inner telescopic ring to perform a smooth and precise radial telescopic movement according to the processor's instructions, thereby achieving compensation and correction of the adapter lens position. For example, the drive component can be a miniature stepper motor drive component. The aforementioned photoelectric alignment sensor, the aforementioned laser coaxial detector, the aforementioned drive assembly, and the aforementioned processor are all integrated into the outer wall of the positioning base.

[0050] The aforementioned processor is configured to perform calibration operations: The first step involves activating the photoelectric alignment sensor and the laser coaxial detector in response to confirmation that the adapter lens has been assembled and upon receiving a start command from the optical module adapter device. The start command indicates that the photoelectric alignment sensor and the laser coaxial detector are activated. Activating the photoelectric alignment sensor and the laser coaxial detector to collect data allows the photoelectric alignment sensor to acquire radial and circumferential angle values ​​of the adapter lens, and the laser coaxial detector to acquire axial and coaxial values ​​between the adapter lens and the optical center of the optomechanical device.

[0051] The second step involves controlling the photoelectric alignment sensor to continuously acquire the radial and circumferential angle values ​​of the adapter lens, and the laser coaxial detector to acquire the coaxial and axial state values ​​of the adapter lens and the optical center of the optomechanical device, based on a preset acquisition cycle. The preset acquisition cycle allows for real-time acquisition of the offset between the adapter lens and the optical center of the optomechanical device. This optical center offset represents the difference between the optical center of the adapter lens and the optical center of the optomechanical device. For example, the preset acquisition cycle could be 5 seconds per acquisition. The radial state value represents the radial offset distance and direction of the geometric center of the adapter lens relative to the optical center of the optomechanical device. The circumferential angle value represents the torsional angle of the adapter lens around the optical center axis of the optomechanical device. The axial state value represents the tilt angle of the adapter lens relative to the optical center axis of the optomechanical device.

[0052] The third step involves generating radial position deviation, circumferential torsional deviation, axial tilt deviation, and coaxial deviation values ​​based on the aforementioned radial state values, pre-stored initial lens assembly reference values, circumferential angle values, pre-stored horizontal lens attitude reference values, axial state values, pre-stored vertical lens attitude reference values, coaxial state values ​​of the optical center, and pre-stored optical path coaxial reference values. Specifically, the pre-stored initial lens assembly reference value represents the radial coordinate that the optical center of the adapter lens should be in when it coincides with the optical center of the optomechanical device in a plane perpendicular to the optical axis during assembly, serving as a reference value to determine whether the adapter lens has experienced radial offset. The pre-stored horizontal lens attitude reference value represents the angle at which the pre-set circumferential reference line of the adapter lens is parallel to the optical center of the optomechanical device in the assembled state, serving as a reference value to determine whether the adapter lens has experienced circumferential torsional distortion. The pre-stored vertical lens attitude reference value represents the angle at which the normal line of the adapter lens is parallel to the optical center axis of the optomechanical device in the assembled state, serving as a reference value to determine whether the adapter lens has experienced axial tilt. The aforementioned pre-stored optical path coaxial reference value characterizes the coaxiality of the adapter lens and the optomechanical equipment when their optical central axes coincide in the assembled state. It serves as a reference value to determine whether and to what extent the optical centers of the adapter lens and the optomechanical equipment deviate from their axes. The aforementioned radial position deviation value characterizes the offset distance and direction of the optical center of the adapter lens relative to the pre-stored initial assembly reference value in a plane perpendicular to the optical central axis of the optomechanical equipment. For example, if the radial state values ​​X = 0.04 mm and Y = -0.02 mm, and the pre-stored initial assembly reference values ​​are X = 0.00 mm and Y = 0.00 mm, the radial position deviation values ​​are ΔX = +0.04 mm and ΔY = -0.02 mm. The aforementioned circumferential torsional deviation value characterizes the torsional angle of the adapter lens's circumferential reference line around the optical central axis of the optomechanical equipment relative to the pre-stored horizontal attitude reference value. For example, if the circumferential angle value is 3.5°, and the pre-stored horizontal attitude reference value is 0.0°, the circumferential torsional deviation value is +3.5°. The aforementioned axial tilt deviation values ​​characterize the angle between the normal direction of the adapter lens, relative to a pre-stored vertical attitude reference, and the optical central axis of the optomechanical device. For example, if the axial tilt value is 0.8° and the pre-stored vertical attitude reference value is 0.0°, the axial tilt deviation value is +0.8°. The aforementioned coaxial deviation values ​​characterize the deviation of the optical central axis of the adapter lens from the optical central axis of the optomechanical device, relative to a pre-stored optical path coaxial reference value. For example, if the optical central coaxial value is 0.03mm and the pre-stored optical path coaxial reference value is 0.00mm, the coaxial deviation value is +0.03mm.In practice, the processor can determine the radial position deviation, circumferential torsion deviation, axial tilt deviation, and coaxial deviation values ​​based on the radial state value, the pre-stored initial assembly reference value of the lens, the circumferential angle value, the pre-stored horizontal attitude reference value of the lens, the axial state value, the pre-stored vertical attitude reference value of the lens, the coaxial state value of the optical center, and the pre-stored coaxial reference value of the optical path through a geometric attitude difference algorithm.

[0053] The fourth step involves generating a multi-dimensional calibration control signal in response to any deviation value exceeding a corresponding preset safety threshold. Each deviation value can represent a radial position deviation, circumferential torsional deviation, axial tilt deviation, or coaxial deviation. The preset safety threshold represents the maximum permissible deviation range for any of these deviation values. For example, the preset safety threshold for radial position deviation could be ±0.05 mm, for circumferential torsional deviation ±1.0°, for axial tilt deviation ±0.5°, and for coaxial deviation ±0.03 mm. The multi-dimensional calibration control signal represents an instruction to calibrate the lens based on any of these deviation values. In practice, the processor can determine the multi-dimensional calibration control signal using a multivariable PID (proportional-integral-derivative) coordinated control algorithm based on the radial position deviation, circumferential torsional deviation, axial tilt deviation, and coaxial deviation values.

[0054] Fifth, based on the aforementioned multi-dimensional calibration and control signals, the processor controls the drive component to adjust the stroke change of the telescopic structure. In practice, the processor controls the drive component according to the aforementioned multi-dimensional calibration and control instructions, thereby controlling the position of the telescopic structure to calibrate the optical center of the adapter lens and the optomechanical device.

[0055] Step 6: Based on the stroke changes of the aforementioned elastic telescopic component, and according to the aforementioned multi-dimensional calibration and control signals, control the aforementioned inner telescopic ring to drive the aforementioned adapter lens to complete compensation and correction. The aforementioned compensation and correction can characterize the operation of restoring the radial position deviation value, circumferential torsional deviation value, axial tilt deviation value, coaxial deviation value, and deviation from the reference value in the aforementioned adapter lens to the corresponding preset safety threshold.

[0056] Step 7: In response to the detection that all deviation values ​​have fallen back to their corresponding preset safety thresholds, a steady-state holding signal is generated. This steady-state holding signal controls the drive component to maintain the compensation correction. All deviation values ​​can include radial position deviation, circumferential position deviation, axial position deviation, and coaxial deviation. The steady-state holding signal characterizes the control signal for the drive component to maintain the position and attitude of the inner telescopic ring after calibration. In practice, the processor can determine the steady-state holding signal based on the radial position deviation, circumferential torsional deviation, axial tilt deviation, and coaxial deviation through a deviation threshold continuous monitoring algorithm.

[0057] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "the inability to capture the coaxial offset of the optical center after lens assembly due to manual adjustment of the optical center by the user alone." This leads to optical center offset after lens installation, resulting in blurred display images and affecting visual clarity and immersion. The reasons are as follows: When using head-mounted display devices for teaching in schools (such as in school laboratories), traditional head-mounted display devices lack the function of automatically generating alignment adjustments based on the optical center. Therefore, relying solely on manual adjustment of the optical center by the user cannot capture the coaxial offset of the optical center after lens assembly, leading to blurred display images and affecting visual clarity and immersion. Solving this problem reduces the likelihood of blurred display images and reduced visual clarity and immersion caused by unfamiliarity with optical center adjustment. To achieve this effect, the processors in some embodiments of this disclosure can collaboratively adjust the optical center of the head-mounted display device using a photoelectric alignment sensor, a laser coaxial detector, and a drive component. This reduces optical center offset caused by unfamiliarity with adjustment and minimizes the blurring of display images and the impact on visual clarity and immersion caused by optical center offset.

[0058] In addressing the technical problems mentioned above, and considering the application scenario—specifically, when using head-mounted display devices for teaching in schools (e.g., in school laboratories)—students must complete a full calibration process every time they change different adapter lenses. This process is cumbersome and time-consuming, often accompanied by the following technical problem: Existing head-mounted display device optical module adapters used in school teaching scenarios lack a function for reusing historical calibration data. This results in a complete recalibration process being performed every time an adapter lens is changed, leading to long waiting times for students taking turns using the device and increasing energy consumption and the risk of lens wear. To meet the following requirements for this application scenario—adapting to the needs of multiple user specifications and simplifying user replacement time—we have decided to adopt the following solution: Optionally, the aforementioned optical module adapter also includes a laser rangefinder and a dot-matrix infrared sensor, both of which are communicatively connected to the aforementioned processor. The laser rangefinder can collect geometrical physical data of the adapter lens (such as lens diameter, lens thickness, edge thickness, and distance from the positioning base bearing surface). For example, the laser rangefinder can be a miniature single-point laser rangefinder. The dot-matrix infrared sensor can collect optical characteristic physical data of the adapter lens (such as lens surface transmittance and refractive index). For example, the dot-matrix infrared sensor can be a miniature integrated infrared transmittance sensor. The laser rangefinder and the dot-matrix infrared sensor can be integrated into the outer wall of the positioning base.

[0059] The aforementioned processor is also configured to perform the following operations: The first step involves, in response to the detection that the adapter lens is mounted on the positioning base, the laser rangefinder sensor collects the geometrical physical data of the adapter lens, and the dot-matrix infrared sensor collects the optical characteristic physical data of the adapter lens, integrating them into the physical attribute data of the adapter lens. The geometrical physical data characterizes the geometric shape and size specifications of the adapter lens, used to distinguish different models of adapter lenses. For example, the geometrical physical data could be a lens diameter of 28mm, a center thickness of 2.2mm, and an edge thickness of 1.8mm. The optical characteristic physical data characterizes the optical performance of the adapter lens, used to achieve accurate lens identification. For example, the optical characteristic physical data could be an infrared transmittance of 88% and a surface reflectance of 4.5%. The physical attribute data represents a comprehensive identifier of the adapter lens's geometric and optical features. For example, the physical attribute data could be a lens diameter of 28mm, a center thickness of 2.2mm, an edge thickness of 1.8mm, an infrared transmittance of 88%, and a surface reflectance of 4.5%. In practice, the processor can determine the physical attribute data from the geometrical physical data and the optical characteristic physical data.

[0060] The second step involves comparing the aforementioned physical attribute data with the physical attribute data in a pre-stored physical attribute database. This pre-stored physical attribute database can represent historical calibration data of the adapter lens whose optical center has been adjusted. This historical calibration data can include geometric dimension physical data, optical characteristic dimension physical data, and a set of associated optical calibration data; alternatively, it can include the physical attribute data of the adapter lens and the specific optical data generated after the calibration operation. This optical calibration data represents the parameters used to calibrate the adapter lens and the optomechanical equipment to achieve optical center alignment.

[0061] In the first sub-execution step, in response to the retrieval of matching physical attribute data, the lens is identified as a pre-recorded adapter lens, and historical calibration data of the pre-recorded adapter lens is retrieved to complete attitude calibration. Here, the attitude calibration of the head-mounted display device characterizes the optical center positioning operation after the adapter lens is installed on the head-mounted display device. The specific type of the head-mounted display device is not limited here; for example, the head-mounted display device can be AR glasses. In practice, the processor can retrieve the historical calibration data of the adapter lens to control the driving components to complete attitude calibration.

[0062] The second sub-execution step, in response to the failure to find matching physical attribute data, determines that the aforementioned adapter lens is not recorded, performs the aforementioned calibration operation, and records the physical attribute data of the aforementioned adapter lens and the dedicated optical data after the aforementioned calibration operation as historical calibration data into the aforementioned pre-stored physical attribute database. The aforementioned dedicated optical data may include radial position compensation travel, circumferential torsion correction angle, and axial tilt fine-tuning amount. The aforementioned radial position compensation travel characterizes the radial movement distance and direction required for the drive component to move the inner telescopic ring radially, causing the radial position deviation value of the adapter lens to fall back to the corresponding preset safety threshold. The aforementioned circumferential torsion correction angle characterizes the torsion angle amount required for the drive component to rotate the inner telescopic ring around the optical center axis of the optomechanical device, causing the circumferential torsion deviation value of the adapter lens to fall back to the corresponding preset safety threshold. The aforementioned axial tilt fine-tuning amount characterizes the tilt angle adjustment amount required for the drive component to move the inner telescopic ring, causing the axial tilt deviation value of the adapter lens to fall back to the corresponding preset safety threshold. For example, radial position compensation travel ±0.03mm, circumferential torsion correction angle -0.8°, and axial tilt fine adjustment +0.4°. These specific optical data characterize the calibration parameters for adapting the above-mentioned lens to its optical properties.

[0063] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "re-executing the complete calibration process every time the adapter lens is replaced," which leads to long waiting times during rotation and increases equipment energy consumption and lens wear risk. The reasons are as follows: When head-mounted display devices are used for teaching in schools (such as in school laboratories), existing head-mounted display device optical module adapters used in school teaching scenarios lack historical calibration data reuse functionality. This results in a complete calibration process being re-executed every time the adapter lens is replaced, which is cumbersome and time-consuming, leading to long waiting times during student rotation and increasing equipment energy consumption and lens wear risk. If the above factors are solved, the alignment parameters of the optical center can be directly configured for reused lenses, reducing waiting time during rotation. To achieve this effect, the processors in some embodiments of this disclosure collect geometric dimension physical data and optical characteristic dimension physical data through laser range sensors and dot matrix infrared sensors, integrate them into physical attribute data, and compare them with a historically stored database to determine the physical attributes, reducing the time wasted on optical center alignment each time the lens is replaced.

[0064] The various embodiments of this disclosure have the following beneficial effects: An optical module adapter device for a head-mounted display device, as provided in some embodiments of this disclosure, allows for rapid disassembly, improving the replacement efficiency of the optical module adapter device and simplifying the assembly / disassembly process. It can meet different visual needs, thereby reducing the discomfort experienced by users wearing traditional eyeglasses, improving user experience, and reducing the risk of damage caused by contact with optical equipment. Specifically, the reasons for the numerous technical problems with existing optical module adapters are as follows: Traditional detachable lenses rely heavily on mechanical fixing structures with screws and clips, resulting in cumbersome and time-consuming disassembly and assembly processes. This leads to inefficiency when users replace lenses and excessively long waiting times when multiple people share the device. Furthermore, traditional optical modules mostly use fixed lenses with non-adjustable prescriptions, failing to meet the needs of users with different vision types. This forces nearsighted users to wear additional eyeglasses when using head-mounted display devices, causing discomfort and obstruction of the periphery of their field of vision. Finally, in traditional technologies, lens disassembly and assembly require direct contact with the optical area or outer shell of the optical engine, and the fixing structure lacks protective design. Repeated disassembly and assembly can cause scratches to the optical engine by lens edges or tools, leading to damage, decreased optical performance, and shortened device lifespan. Based on this, some embodiments of this disclosure provide an optical module adapter for a head-mounted display device. The optical module adapter includes a positioning base, a fixing member, and an adapter lens. The connection structure of the positioning base is fixedly engaged with a pre-set adapter structure of the optomechanical device. The adapter lens is fixed to the bearing surface of the positioning base via the fixing member. The adapter lens and the fixing member form an integrated adapter structure, which is connected to the optomechanical device. Because the positioning base of the optical module adapter is fixedly engaged with the optomechanical device, the optical module adapter can quickly remove the lens, improving the replacement efficiency and simplifying the assembly / disassembly process. Furthermore, because the adapter lens is fixed via the fixing member, it can meet different visual needs, thereby reducing the discomfort experienced by users wearing traditional eyeglasses and improving the user experience. Because the above-mentioned adapter lens and the above-mentioned fastener form an integrated adapter structure and are then connected to the above-mentioned optical and mechanical equipment, the prescription can be changed simply by disassembling and assembling the lens itself, which can reduce the possibility of damage caused by contact with the optical and mechanical equipment.
