[0012] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0013] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0014] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0015] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0016] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0017] It should be noted that all actions of acquiring signals, information or data in the embodiments of the present disclosure are performed in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0018] In an example of this embodiment, a test method for a wearable device is provided, which is applied to a head pressure testing system. The head pressure testing system includes a head mold assembly, and a pressure sensor array is provided on the surface of the head mold assembly.

[0019] In this embodiment, the head pressure test system may include a head mold assembly, which includes multiple head molds 100. Users can assemble or set multiple head molds in advance according to test needs to obtain target head models of different sizes. For example, Figure 2 As shown, the headform assembly includes four headforms: front, left, right, and top. Users can adjust the width of the target head model by setting the distance between the left and right headforms based on testing requirements. Alternatively, they can adjust the height of the target head model by adjusting the height of the top headform, and adjust the distance between the front headform and the other headforms to adjust the length of the target head model. In other embodiments, the headform assembly may include two headforms: front and back.

[0020] In this example, the system may include a fixing device for the head mold assembly, which is used to fix the various head molds to form a target head model.

[0021] In one example of this embodiment, a flexible pressure sensor array can be provided on the surface of the head mold assembly, such as a sensor array composed of a flexible printed circuit board and a graphene piezoresistive film, or a capacitive stretchable sensor. Each sensor can detect a received pressure value, thereby obtaining overall pressure distribution data.

[0022] In one example of this embodiment, the testing method of the wearable device is as follows: Figure 1 As shown, the method includes steps S11 to S13.

[0023] Step S11, obtaining first pressure sensing data generated when the target wearable device is worn on the head mold assembly through the pressure sensor array; In this embodiment, the target wearable device can be a head-mounted device such as a VR headset, an AR headset, an MR (mixed reality) headset, a smart helmet, smart glasses, a headset, or a smart bandage. When the target wearable device to be tested is worn on the headform assembly, the pressure sensor array on the headform assembly can obtain pressure sensing data of the wearable device based on the pressure of the target wearable device.

[0024] Step S12: determining position adjustment information of the target wearable device based on the first pressure sensing data, where the position adjustment information is used to adjust the wearing position to the target position.

[0025] Step S13: When the wearing position is the target position, the wearable device is tested.

[0026] In this example, the pressure sensor data includes the pressure value collected by each pressure sensor and its corresponding identity information. This identity information uniquely identifies each pressure sensor and, based on a pre-stored sensor position mapping, determines the specific physical location of each pressure sensor on the headform assembly. By identifying the identity information of the pressure sensor generating the pressure value, the system can locate the specific area where the wearable device makes contact with the headform assembly and, therefore, infer the device's wearing position.

[0027] Specifically, the identity information may include a sensor's unique identifier (such as a number or ID) and its position coordinates within a preset coordinate system on the surface of the headform assembly. When the target wearable device is worn on the headform assembly, the pressure exerted by it will be detected by one or more pressure sensors. By reading the identity information of these sensors and combining it with their corresponding pressure values, the system can determine the distribution of contact points between the device and the headform. For example, if the pressure value detected by the sensor array in a specific area is greater than a threshold, it indicates that the wearable device is in close contact with this area, thereby determining the device's wearing position. This generates position adjustment information used to calibrate the wearable device's wearing position. For example, if the wearable device is not worn in the target position, the head pressure testing system can notify the user through voice or on the display unit that the wearable device is currently worn in the target position, allowing the user to manually adjust the wearable device's wearing position or manipulate the head pressure testing system until it is worn in the target position.

[0028] In this example, the head mold assembly can be equipped with an automatic adjustment mechanism, such as a micromotor or pneumatic device, to automatically fine-tune the device's position. Alternatively, the system can output prompts, such as voice or image guidance, to manually re-don the device until the pressure sensor data meets the target position requirements.

[0029] In this example, the target location can be determined based on the type of target wearable device and the test type. Tests on wearable devices can include pressure distribution testing, clamping force testing, or display and audio effect testing.

[0030] The specific definition of the target location is determined based on the type of wearable device being tested and the type of test. For example, for a virtual reality (VR) head-mounted display, the target location must ensure that the device's contact surfaces with the user's forehead, sides, and back of the head match for pressure distribution analysis. For augmented reality (AR) glasses, the target location must include the contact surfaces between the temples and the sides of the head, just above the auricle, to provide a benchmark for clamping force or pressure distribution testing.

[0031] This example provides a wearable device testing method. This system utilizes a head pressure testing system with an integrated pressure sensor array and a corresponding testing method. By acquiring the first pressure sensing data generated by the wearable device on the head mold assembly, the system determines position adjustment information used to calibrate the wearable device's wearing position. This allows the user or device to adjust the wearable device's wearing position, ensuring that the wearable device can be quickly and accurately replicated to the same target position for each test, significantly improving test consistency and repeatability. Through automated adjustment and evaluation processes, test efficiency is significantly improved, providing a reliable and efficient solution for wearable device design improvement and quality verification.

[0032] In an example of this embodiment, position adjustment information of a target wearable device is determined based on first pressure sensing data, including: determining a first pressure distribution area of ​​the first pressure sensing data on a pressure sensor array; determining a degree of overlap between the first pressure distribution area and a target pressure distribution area, wherein the target pressure distribution area corresponds to a target position; when the degree of overlap is greater than a target threshold and the maximum pressure sensing data in the first pressure sensing data is within the target pressure distribution area, determining that the wearing position is the target position, and generating first position adjustment information indicating that the wearing position does not need to be adjusted; when the degree of overlap is less than or equal to the target threshold, or the maximum pressure sensing data is outside the target pressure distribution area, determining that the wearing position is not at the target position, and generating second position adjustment information indicating that the wearing position needs to be adjusted.

[0033] In this example, the first pressure sensing data is analyzed and processed based on the mapping between the identity information and position of each sensor in the pressure sensor array to determine the actual pressure distribution range generated on the surface of the head mold assembly, namely the first pressure distribution area. This area reflects the actual contact position and coverage of the wearable device with the head mold assembly when currently worn.

[0034] Furthermore, the system can pre-store a target pressure distribution area corresponding to the target wearing state, which is associated with the target position. By calculating the overlap between the first pressure distribution area and the target pressure distribution area, a quantitative assessment of the current wearing state can be made. The overlap can be determined by calculating the area ratio of the overlapping portion of the two areas.

[0035] During the judgment stage, if the following two conditions are met at the same time, it is determined that the current wearing position has reached the target position: first, the degree of overlap is greater than the preset target threshold, indicating that the current contact area as a whole is basically consistent with the ideal area; second, the sensor corresponding to the maximum pressure value in the first pressure sensing data is located within the target pressure distribution area, ensuring that the main force points of the device are within the expected design range.

[0036] If any of the above conditions are not met, that is, the overlap does not reach the target threshold, or the maximum pressure sensor data is outside the target pressure distribution area, the system determines that the current wearing position is deviated and generates an adjustment instruction. This instruction can be used to drive the automatic adjustment mechanism to fine-tune the device position, or output a prompt message to guide users to re-wear the device until the pressure sensor data meets the target position requirements.

[0037] Through the dual judgment mechanism of regional overlap and maximum pressure position, the present invention achieves accurate evaluation and correction of the wearing status of the wearable device, effectively improving the reliability of the test process and the consistency of the user experience.

[0038] In an example of this embodiment, before determining the position adjustment information of the target wearable device based on the first pressure sensing data, the method also includes: determining a working mode of the head pressure testing system, the working mode including a calibration mode and a test mode; when the working mode is the calibration mode, using the third pressure distribution area as the target pressure distribution area of ​​the target wearable device, wherein the third pressure distribution area corresponds to the type of the target wearable device; when the working mode is the test mode, using the second pressure distribution area as the target pressure distribution area of ​​the target wearable device, wherein the second pressure distribution area corresponds to the wearing position of the target wearable device in the calibration mode.

[0039] Before adjusting the wearing position of the target wearable device based on the first pressure sensing data, the system can first determine the operating mode of the head pressure test system, including calibration mode and test mode. For example, if the target wearable device is being tested for the first time, the operating mode can be set to calibration mode; if it is not the first time, it can be set to test mode. The determination can be made by querying whether the wearable device type of the device exists in the historical test record database. If no relevant record is found, it is determined to be an initial test; otherwise, it is not an initial test.

[0040] When the system is in test mode, the system calls the pressure distribution information corresponding to the wearing position of the device in calibration mode from historical test data, that is, the second pressure distribution area, and uses it as the target pressure distribution area in the current test mode.

[0041] Because the optimal wearing position and corresponding pressure distribution of the same wearable device are reproducible across multiple tests due to its structural characteristics and fit with the headform assembly, directly using the established area in the calibration pattern as the target for this adjustment significantly reduces the time required for repeated calibration, improves testing efficiency, and avoids algorithmic errors that may be introduced by recalculating the target area each time, thereby ensuring test consistency and reliability.

[0042] When the system is in calibration mode, the system determines the third pressure distribution area as the target pressure distribution area for the device. The third pressure distribution area is not customized for a single device, but is associated with the type of target wearable device. For example, different types of head-mounted devices such as VR headsets, AR headsets, MR (mixed reality) headsets, smart helmets, smart glasses, smart bands, etc., each have a pre-generated default pressure distribution area that matches their hardware characteristics.

[0043] The basis for determining the third pressure distribution area may include the type of device. Different types of wearable devices have significant differences in their structure, weight distribution, and ideal contact area with the human head. For example, the ideal pressure of smart glasses is mainly distributed on the bridge of the nose, above the cheekbones, and near the temples; while the pressure of headphones is more concentrated around the auricles and the top of the head. The system's built-in device type library pre-stores typical pressure distribution templates for various types of devices, which can automatically match the corresponding third pressure distribution area based on the device type identifier.

[0044] In this embodiment, the distribution density of the pressure sensor array of the head mold assembly can be varied. Those skilled in the art can customize the pressure sensor array distribution on the head mold assembly based on actual testing requirements, thereby reducing hardware costs while ensuring effective testing. The determination of the third pressure distribution area can also take into account the sensor distribution density of the pressure sensor array covering the head mold assembly surface. The sensor distribution density determines the spatial resolution of pressure sensing. A higher density allows for more precise definition of the boundaries of the third pressure distribution area. Conversely, a lower density requires an appropriate expansion of this area to ensure fault tolerance and avoid the inability to reliably capture the device's actual contact range due to large sensor spacing. For example, for an AR headset, the primary contact points with the user are the nose pads and the temples, which correspond to the user's nose and ears. Therefore, the head mold assembly's pressure sensor array can be configured with a higher sensor density to ensure accurate test results. For a VR headset, the primary contact points with the user are the eye sockets, sides, and back of the head. Therefore, the head mold assembly's pressure sensor array can also be configured with a higher sensor density in these locations. For other locations, a relatively lower sensor density can be used. Therefore, the third pressure distribution area may also be set as a range of positions with a relatively high sensor density that covers all major contact positions of this type of device.

[0045] Compared to the optimized second pressure distribution area used in test mode, the third pressure distribution area serves as an initial, more inclusive reference in calibration mode. Its larger spatial range allows the system to obtain a wider range of pressure data during calibration mode wear attempts, providing a sufficient data foundation for subsequent precise adjustments and learning optimization. This design effectively ensures the calibration mode's fault tolerance and success rate, providing a solid foundation for establishing the device's personalized second pressure distribution area.

[0046] In one example of this embodiment, the head pressure testing system further includes an adjustment mechanism, the head mold assembly is disposed on the adjustment mechanism, and the adjustment mechanism is used to adjust the distance between each head mold in the head mold assembly. Before obtaining first pressure sensing data generated when the target wearable device is worn on the head mold assembly through the pressure sensor array, the method further includes: adjusting the distance between the head mold assemblies to construct a first target head model; and testing the target wearable device, including: Obtain pressure distribution data of the target wearable device on the first target head model.

[0047] The head pressure testing system also includes an adjustment mechanism, to which the headform assembly is fixedly mounted. The adjustment mechanism adjusts the relative distance between one or more headforms, thereby dynamically simulating physical models of heads with varying head circumferences and shapes.

[0048] In one example, the system controls the adjustment mechanism based on test requirements (e.g., simulating the head circumference percentile of a specific population or head sizes that meet certain standard specifications), driving the head mold assembly to a predetermined spatial position. Subsequently, the target wearable device is placed on this constructed first target head mold. Once the device is worn, the pressure generated by its contact with the head mold surface is captured in real time by the pressure sensor array covering the head mold surface. The system then obtains pressure distribution data at this point. This data not only includes the pressure values ​​and identification information of each sensor, but also records the comprehensive force state of the device on the current specific head mold.

[0049] This approach enables the rapid reconstruction of diverse head physical models using a single hardware system through software control, significantly expanding test coverage. This method overcomes the limited testing range of traditional fixed head models and the overly restrictive clamping force testing. Based on data from the pressure sensor array, the system accurately maps and analyzes the pressure distribution area at the interface between the device and the head, not just the overall clamping force. This allows for a more scientific and comprehensive assessment of the device's actual wearing comfort and the rationality of its pressure distribution.

[0050] In one example of this embodiment, the adjustment mechanism also includes a pressure sensor, wherein the pressure sensor is arranged at the connection position between the adjustment mechanism and the head mold assembly; testing the wearable device also includes: obtaining clamping force data of the target wearable device on the first target head model.

[0051] Pressure sensors are integrated at key locations connecting the adjustment mechanism to the headform assembly. These sensors, located at the adjustment mechanism's actuation points or along the force transmission path between the support structure and the headform body, directly monitor and measure the overall clamping force exerted by the target wearable device on the headform assembly during testing.

[0052] During wearable device testing, the system not only captures pressure distribution data at the interface between the device and the headform, but also uses the pressure sensor integrated into the adjustment mechanism to obtain real-time data on the clamping force exerted by the target wearable device on the first target headform. This "clamping force" is a holistic measurement that represents the total pressure exerted on one side of the headform by the wearable device (such as the temples of smart glasses or the headband of headphones) to maintain its stable fit.

[0053] In this case, clamping force data also provides a crucial supplement to assessing the comfort and safety of wearable devices. On the one hand, excessive clamping force directly indicates that the device may be too oppressive and lack comfort; on the other hand, too low a clamping force may indicate an unstable fit and prone to slipping. By comparing real-time clamping force data with preset safety and comfort thresholds, the system can quantitatively evaluate the device's mechanical design.

[0054] The head pressure test system also integrates a display unit, which communicates with other devices in the system and is used to provide intuitive visual feedback to the tester. The display unit is usually an LCD or OLED display, and its core function is to render and display a dedicated graphical user interface. In this graphical user interface, the system visualizes the key information during the test, among which the most important elements are the first pressure distribution area and the target pressure distribution area. Figure 3 As shown in the figure, the black part is the first pressure distribution area, and the dotted box part is the target pressure distribution area.

[0055] The present disclosure also provides a wearable device testing system 200, such as Figure 4 As shown, it includes a processor 201, a memory 202, an adjustment mechanism 203 and a head mold assembly 204, the head mold assembly 204 is set on the adjustment mechanism 203, the adjustment mechanism 203 is used to adjust the distance between the head mold assemblies 204, a pressure sensor array is set on the surface of the head mold assembly 204, and the memory 202 stores computer instructions. When the computer instructions are executed by the processor 201, any method of the test method embodiment of the wearable device is implemented.

[0056] Optionally, the adjustment mechanism further includes a pressure sensor, wherein the pressure sensor is arranged at a connection position between the adjustment mechanism and the head mold assembly.

[0057] Optionally, the system further includes a display unit for displaying a graphical user interface, wherein the user interface displays a first pressure distribution area of ​​the first pressure sensing data on the pressure sensor array and a target pressure distribution area corresponding to the target position.

[0058] The adjustment mechanism provided by the embodiment of the present invention includes: Base 1; a first driving member 2 and a second driving member 3, wherein the first driving member 2 and the second driving member 3 are respectively provided on the base 1, and a driving direction of the first driving member 2 and a driving direction of the second driving member 3 form an included angle; A first support member 4 and a second support member 5, wherein the driving end of the first driving member 2 is in transmission connection with the first support member 4, and the driving end of the second driving member 3 is in transmission connection with the second support member 5, and the first support member 4 and the second support member 5 are configured to respectively cooperate with the corresponding head mold 100; A first detecting member 6 and a second detecting member 7, wherein the first detecting member 6 is configured to detect the displacement value of the first supporting member 4, and the second detecting member 7 is configured to detect the displacement value of the second supporting member 5, and the first detecting member 6 is communicatively connected to the first driving member 2, and the second detecting member 7 is communicatively connected to the second driving member 3.

[0059] Specifically, base 1 serves as the mounting base for the entire adjustment mechanism and can be made of a high-strength, high-rigidity metal material, such as aluminum alloy or stainless steel. Base 1 is typically a rectangular flat plate with a precision-machined surface to ensure flatness, providing a stable support and mounting base. Mounting holes can be provided at each of the four corners of base 1 for securing the entire adjustment mechanism to a work platform or other equipment.

[0060] The first driving member 2 and the second driving member 3 can be servo motors or cylinders, and the first driving member 2 and the second driving member 3 can be fixed to corresponding positions of the base 1 by bolts. Figure 6 As shown, grooves can be opened at corresponding positions of the base 1, and the first driving member 2 and the second driving member 3 can be embedded in the corresponding grooves. This can facilitate the assembly of the driving members and help improve the assembly accuracy. At the same time, relatively independent areas can be formed on the base through the grooves, so that the driving members embedded therein can operate more stably.

[0061] Among them, an angle is set between the driving direction of the first driving member 2 and the driving direction of the second driving member 3, that is, the driving directions of the two are inconsistent, so that multiple head molds 100 can be independently driven and adjusted in two different directions, so as to meet the wearing requirements of head mold assemblies of different sizes, and also facilitate the measurement of the clamping force of head-worn products of different sizes. For example, in human head mold simulation experiments in the medical field, the position of the head mold 100 in both the horizontal and vertical directions can be accurately adjusted according to different experimental requirements to simulate the head posture in various actual scenarios and provide more accurate data support for the experiment. In fields such as industrial design or virtual reality, the angle and position of the head mold 100 can also be conveniently adjusted to meet different display or interaction needs.

[0062] In one embodiment, the driving direction of the first driving member 2 can be set to the horizontal X-axis direction, and the driving direction of the second driving member 3 can be set to the horizontal Y-axis direction, so that there is a 90° angle between the driving directions of the two driving members, so as to achieve independent adjustment of the head mold 100 in two mutually perpendicular directions.

[0063] In one embodiment, the first drive member 2 and the second drive member 3 can each be connected to an external control system via a controller. The control system can send control signals to the first drive member 2 and the second drive member 3 according to a preset program or received instructions, and control their start, stop, forward and reverse rotation, and operating speed and displacement.

[0064] like Figures 5 to 7 As shown, the first support member 4 and the second support member 5 can be made of a metal material with good rigidity. Rubber gaskets can be provided on the surfaces of the first and second support members 4 and 5 that contact the corresponding headform 100. The rubber gaskets have a certain degree of elasticity and friction to better fit the headform 100, preventing the headform 100 from slipping during adjustment. They also provide cushioning and protection for the headform 100.

[0065] In one embodiment, the driving end of the first driving member 2 can be connected to the first support member 4 via a coupling. This coupling utilizes an elastic pin coupling, which has a certain ability to compensate for relative displacement between the two shafts. This allows for smooth transmission of the power of the first driving member 2 to the first support member 4, reducing shock and vibration during transmission and avoiding problems such as positional offset or loss of adjustment control of the head mold 100 due to unstable transmission. Similarly, the driving end of the second driving member 3 can also be connected to the second support member 5 via an elastic pin coupling, allowing for smooth transmission of the power of the second driving member 3 to the second support member 5.

[0066] Because the first and second drive members 2 and 3 independently drive the first and second support members 4 and 5, the headform 100 can be adjusted independently in different directions during the adjustment process without being affected by other directions. This independent adjustment method also increases adjustment flexibility. The operator can adjust the position of the headform 100 in one direction first, then adjust the position in another direction, or perform fine-tuning in both directions simultaneously, to quickly and accurately achieve the desired headform 100 posture.

[0067] The first and second support members 4, 5 respectively mate with their corresponding head mold 100. Specifically, this mate can be achieved by inserting the first and second support members 4, 5 into grooves or slots on the head mold 100 that match their shapes, ensuring a stable connection. When the first and second drive members 2, 3 are activated, they respectively drive the first and second support members 4, 5, to move, thereby adjusting the position of the head mold 100.

[0068] This makes the adjustment mechanism highly versatile. Headforms 100 of varying sizes and shapes can be adapted to the adjustment mechanism by designing corresponding support members. For example, in the medical field, the first and second support members 4 and 5 can be customized according to the size and shape of headforms 100 for patients of different age groups, making the adjustment mechanism widely applicable to various types of headforms 100, such as those for children and adults. In the field of industrial design, the support members can also be replaced to accommodate product headforms 100 of varying shapes and sizes, thereby increasing the applicability and efficiency of the adjustment mechanism.

[0069] like Figure 5 As shown, the first detection member 6 and the second detection member 7 can be laser, photoelectric, Hall-type or other displacement sensors, which can accurately measure the displacement of the corresponding support member and convert the displacement signal into an electrical signal and output it to the controller.

[0070] Furthermore, the first detection member 6 and the second detection member 7 are respectively connected to the corresponding drive members via signal lines or wireless communication. During the adjustment process, the first detection member 6 can detect the displacement value of the first support member 4 in real time, and convert the displacement signal into an electrical signal and send it to the control circuit of the first drive member 2; the second detection member 7 can detect the displacement value of the second support member 5 in real time, and send the displacement signal to the control circuit of the second drive member 3. The control circuits of the first drive member 2 and the second drive member 3 compare the received displacement signal with the preset target displacement value. If there is a deviation, the operating state of the corresponding drive member is adjusted until the displacement of the first support member 4 and the second support member 5 reaches the target value, thereby achieving precise adjustment of the position of the head mold 100.

[0071] Thus, through this closed-loop feedback control system, the driver can timely adjust its operating state based on the detected deviation between the actual displacement of the corresponding support member and the target displacement, such as changing speed, direction, or stopping operation, thereby achieving precise control of the position of the headform 100. Compared with traditional open-loop control adjustment mechanisms, the adjustment mechanism of the present invention can greatly improve adjustment accuracy, control displacement errors to a very small range, and ensure that the headform 100 accurately reaches the preset position.

[0072] Furthermore, the communication connections between the first detection element 6 and the first drive element 2, and between the second detection element 7 and the second drive element 3, also enable intelligent control of the adjustment mechanism. The operator can preset the target position parameters of the headform 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding drive elements based on the displacement information fed back by the detection elements, enabling automated adjustment of the position of the headform 100. This intelligent control approach significantly simplifies the operational process, reduces manual intervention, and improves operational efficiency and accuracy.

[0073] Optionally, it also includes a first transmission member 8 and a second transmission member 9, the driving end of the first driving member 2 is transmission-connected to the first transmission member 8, the driving end of the second driving member 3 is transmission-connected to the second transmission member 9, and the first support member 4 is connected to the first transmission member 8, and the second support member 5 is connected to the second transmission member 9.

[0074] like Figures 5 to 7 As shown, the first driving member 2 and the second driving member 3 are both servo motors, and the first transmission member 8 and the second transmission member 9 are both slide rods connected to the driving ends of the servo motors. Driven by the servo motors, the slide rods can generate precise linear motion and drive the supporting members on them to move to a preset position.

[0075] Optionally, a control member 10 is further included, and the control member 10 is arranged on the base 1 , and the first detection member 6 , the second detection member 7 , the first driving member 2 and the second driving member 3 are respectively connected to the control member 10 for communication.

[0076] Specifically, the first detection member 6 and the second detection member 7 are capable of detecting the displacement values ​​of the first support member 4 and the second support member 5 in real time and feeding this data back to the control member 10. The control member 10, or controller, compares the feedback displacement values ​​with the preset target displacement values ​​in real time. If any deviation is detected, it adjusts the operating state of the corresponding drive member, such as by changing the speed or direction, to eliminate the deviation and achieve precise closed-loop feedback control. This control method can promptly correct errors during the adjustment process and control the displacement error of the headform 100 to a very small range, thereby meeting the high-precision position requirements of the headform 100 in fields such as medical treatment and scientific research.

[0077] The adjustment of the head model 100 often involves parameters in multiple directions, such as horizontal displacement and vertical displacement. The control member 10 can simultaneously process the displacement information in multiple directions fed back by the first detection member 6 and the second detection member 7, and accurately control the actions of the first drive member 2 and the second drive member 3 according to a preset collaborative adjustment algorithm, thereby achieving coordinated and precise adjustment of parameters in multiple directions. For example, in a virtual reality interaction scenario, in order for the head model 100 to accurately simulate the user's head movement, it is necessary to adjust the position and angle of the head model 100 in multiple directions at the same time. The control member 10 can accurately control the corresponding drive member based on the user's movement data, so that the movement of the head model 100 is highly consistent with the user's actual movement, thereby enhancing the realism of the virtual reality experience.

When the first reflective member 11 moves along with the first support member 4, the first laser sensor can emit laser light toward the first reflective member 11 and receive laser light reflected from the first reflective member 11, thereby obtaining the real-time displacement of the first support member 4 and facilitating adjustment of the driving state of the first driving member 2.

[0080] Similarly, the second reflective member 12 can also be a reflective plate, and the second reflective member 12 is connected to the second transmission member 9 or the second support member 5 so that the second reflective member 12 can move along with the second support member 5. When the second reflective member 12 moves along with the second support member 5, the second laser sensor can emit laser light toward the second reflective member 12 and receive laser light reflected from the second reflective member 12, thereby obtaining the real-time displacement of the second support member 5 and facilitating adjustment of the driving state of the second driving member 3.

[0081] Optionally, the laser sensor and the corresponding reflector are coaxially arranged; Alternatively, the angle between the axes of the laser sensor and the corresponding reflector does not exceed 45 degrees.

[0082] In one embodiment, the first laser sensor and the first reflector 11 can be coaxial, and the second laser sensor and the second reflector 12 can be coaxial. That is, the laser sensors and the corresponding reflectors are completely coaxial, so that the emission optical path and the receiving optical path of the laser completely overlap, thereby eliminating the measurement blind spot caused by the optical path deviation of the laser sensor, thereby improving the detection accuracy and real-time response capability of the laser sensor.

[0083] In one embodiment, the axes of the first laser sensor and the first reflector 11, and the axes of the second laser sensor and the second reflector 12 can be configured to have an angle, that is, the laser sensors and the corresponding reflectors are not coaxial. On the one hand, this can accommodate the complex spatial layout within the adjustment mechanism and facilitate optimization of the internal layout of the adjustment mechanism. On the other hand, setting the angle between the axes to be less than or equal to 45 degrees can also improve the environmental adaptability of the laser sensors through special coating processes.

While realizing convenient installation of the first support member 4 and the first reflector 11, it can also avoid friction and wear between the first support member 4 and the first reflector 11 and the first transmission member 8, which helps to ensure the normal operation of the first support member 4 and the first reflector 11.

[0086] Moreover, the driving force transmission path formed by the first driving member 2-first transmission member 8-first connecting member 13-first support member 4 and first reflector 11 can also buffer the driving force output by the first driving member 2, avoiding the risks caused by the driving force directly acting on the first support member 4 and the first reflector 11.

[0087] Similarly, the second connecting member 14 can also be a connecting plate, which is arranged on the second transmission member 9 and then the second support member 5 and the second reflector 12 are arranged on it. While realizing the convenient installation of the second support member 5 and the second reflector 12, it can also avoid friction and wear between the second support member 5 and the second reflector 12 and the second transmission member 9, which helps to ensure the normal operation of the second support member 5 and the second reflector 12.

[0088] In addition, the driving force transmission path formed by the second driving member 3-second transmission member 9-second connecting member 14-second support member 5 and second reflector 12 can also buffer the driving force output by the second driving member 3, avoiding the risks caused by the driving force directly acting on the second support member 5 and the second reflector 12.

[0095] Similarly, the second detection member 7 can also be set as a second pull-wire rangefinder, which is placed at a corresponding position on the base 1 and has its pull rope connected to the second support member 5 or the second transmission member 9, so that when the second support member 5 moves along with the second transmission member 9, the second pull-wire rangefinder can detect the displacement of the second support member 5 in real time, thereby facilitating adjustment of the driving state of the second driving member 3.

[0096] Optionally, the first detection member 6 and / or the second detection member 7 can also be a linear displacement sensor, which is arranged on the corresponding transmission member or the corresponding support member, so that the linear displacement sensor can accurately measure the linear displacement of the corresponding support member and convert the displacement signal into an electrical signal output to facilitate adjustment of the driving state of the corresponding driving member.

[0097] Optionally, the driving direction of the first driving member 2 is perpendicular to the driving direction of the second driving member 3 .

[0098] Specifically, the driving directions of the first driving member 2 and the second driving member 3 can be set to the X direction and the Y direction respectively, so as to achieve the horizontal XY direction position adjustment of the head mold 100; the driving directions of the first driving member 2 and the second driving member 3 can also be set to the X direction and the Z direction respectively, so as to achieve the XZ direction position adjustment of the head mold 100; the driving directions of the first driving member 2 and the second driving member 3 can also be set to the Y direction and the Z direction respectively, so as to achieve the YZ direction position adjustment of the head mold 100, thereby meeting different adjustment requirements.

[0099] Furthermore, arranging the driving directions of the first driving member 2 and the second driving member 3 to be perpendicular to each other can also facilitate the arrangement of related structures, thereby reducing the difficulty of assembling the adjustment mechanism.

[0100] Optionally, it also includes a third driving member 15, a third supporting member 16 and a third detecting member 17, the third driving member 15 is arranged on the base 1, the driving end of the third driving member 15 is transmission-connected to the third supporting member 16, the third supporting member 16 is configured to cooperate with the corresponding head mold 100, the third detecting member 17 is configured to be able to detect the displacement value of the third supporting member 16, the third detecting member 17 is communicatively connected with the third driving member 15, and the driving directions of the first driving member 2, the second driving member 3 and the third driving member 15 are perpendicular to each other.

[0101] like Figures 5 to 7As shown, the first drive member 2 drives in the X direction, the second drive member 3 drives in the Y direction, and the third drive member 15 drives in the Z direction, thereby facilitating multi-directional position adjustment of the head mold 100 in the X, Y, and Z directions. A Z-direction bracket can be installed on the base 1, and the third drive member 15 can be mounted on this bracket, with the drive direction of the third drive member 15 oriented in the Z direction. The third support member 16 is then connected to the drive end of the third drive member 15, either directly or via a third transmission member 18, so that the third drive member 15 can drive the third support member 16 in the Z direction to adjust the position of the upper head mold.

[0102] Among them, the third detection member 17 can use laser, photoelectric, Hall type and other displacement sensors. These displacement sensors can accurately measure the displacement of the third support member 16 and convert the displacement signal into an electrical signal and output it to the controller to facilitate adjustment of the driving state of the third driving member 15.

[0103] like Figures 5 to 7 As shown, it also includes a third transmission member 18, a third connecting member 20, a third reflecting member 21 and a bracket 22. First, the bracket 22 is connected to the base 1 along the Z direction, and then the third transmission member 18 is connected to the bracket 22. Then, the third connecting member 20 is connected to the third transmission member 18. Finally, the third support member 16 and the third reflecting member 21 are respectively connected to two adjacent sides of the third connecting member 20, and the third reflecting member 21 is directed towards the third detection member 17, so that the third detection member 17 can detect the displacement value of the third support member 16.

[0104] Optionally, the head mold assembly includes a front head mold, a left head mold, a right head mold and an upper head mold, the driving direction of the first driving member 2 is the X direction, the driving direction of the second driving member 3 is the Y direction, and the driving direction of the third driving member 15 is the Z direction, so that the first support member 4 can cooperate with the front head mold, the second support member 5 can cooperate with the left head mold and the right head mold, and the third support member 16 can cooperate with the upper head mold.

[0105] like Figures 5 to 7 As shown, driven by the first driver 2, the first support member 4 can move in the X direction and adjust the position of the corresponding front headform; driven by the second driver 3, the second support member 5 can move in the Y direction and adjust the position of the corresponding left and right headforms; driven by the third driver 15, the third support member 16 can move in the Z direction and adjust the position of the corresponding upper headform. In this way, the three drivers can achieve independent adjustment of the headform 100 in multiple directions (X, Y, and Z) to suit different wearing requirements.

[0106] Furthermore, the communication connections between the first detection member 6 and the first drive member 2, the second detection member 7 and the second drive member 3, and the third detection member 17 and the third drive member 15 also enable intelligent multi-directional control of the adjustment mechanism in X, Y, and Z directions. The operator can preset the target position parameters of the headform 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding drive members based on the displacement information fed back by the detection members, enabling automated adjustment of the position of the headform 100. This intelligent control approach significantly simplifies the operational process, reduces manual intervention, and improves operational efficiency and accuracy.

[0107] Optionally, the second transmission member 9 is further included, and the driving end of the second driving member 3 is in transmission connection with the second transmission member 9. The second supporting member 5 includes a first column 51 and a second column 52 arranged in the same row along the Y direction, and the first column 51 and the second column 52 are respectively connected to the second transmission member 9; Driven by the second driving member 3 , the second transmission member 9 can drive the first column 51 and the second column 52 to move in opposite directions.

[0108] Specifically, the second driving member 3 can be a servo motor, and the second transmission member 9 is a slide rod connected to the driving end of the servo motor. Driven by the servo motor, the slide rod can generate precise linear motion and drive the second support member 5 thereon to move to a preset position.

[0109] like Figures 5 to 7 As shown, the second support member 5 includes a first column 51 and a second column 52 arranged in the same row and spaced apart along the Y direction. The first column 51 and the second column 52 are respectively connected to corresponding positions of the second transmission member 9. One of the first column 51 and the second column 52 is formed to cooperate with the left headform, and the other of the first column 51 and the second column 52 is formed to cooperate with the right headform, so as to facilitate the position adjustment of the left and right headforms.

[0110] Driven by the second driving member 3, the second transmission member 9 can drive the first column 51 and the second column 52 to move in opposite directions, that is, drive the first column 51 and the second column 52 to move closer to or away from each other, thereby realizing the position adjustment of the left and right head molds.

[0111] Optionally, the second transmission member 9 has a first external thread and a second external thread, the first column 51 has a first internal thread, and the second column 52 has a second internal thread. The first internal thread is threadedly connected to the first external thread, and the second internal thread is threadedly connected to the second external thread, and the thread rotation directions of the first external thread and the second external thread are opposite.

[0112] Specifically, the first external thread and the second external thread on the second transmission member 9 can be set to have the same thread pitch and opposite rotation direction, so that under the drive of the second driving member 3, the first column 51 and the second column 52 can produce displacements in opposite directions, that is, reverse synchronous motion, so as to achieve synchronous position adjustment of the left and right head molds.

[0113] In this way, the second transmission member 9 with reverse threads can be used to achieve a bidirectional driving function without the need for additional components such as anti-loosening nuts and locking washers, which helps to reduce the production cost and assembly difficulty of the adjustment mechanism.

[0114] Optionally, the second driving member 3 includes a first sub-driving member and a second sub-driving member, and the second transmission member 9 includes a first section and a second section arranged at intervals, the driving end of the first sub-driving member is transmission-connected to the first section, and the driving end of the second sub-driving member is transmission-connected to the second section, the first column 51 is connected to the first section, and the second column 52 is connected to the second section, and the driving direction of the first sub-driving member is opposite to the driving direction of the second sub-driving member, so that the first sub-driving member and the second sub-driving member can be used to respectively drive the first column 51 and the second column 52 to approach or move away from each other, thereby also realizing independent position adjustment of the left and right head molds.

[0115] In this way, the two sub-driving members can be used to realize independent driving of the two uprights, so that the positions of the left headform and the right headform can be adjusted respectively, so as to adapt to different wearing requirements.

[0116] Optionally, the third support member 16 is an L-shaped structure.

[0117] like Figures 5 to 7 As shown, the cross section of the third support member 16 is L-shaped along the XZ plane, so that the L-shaped third support member 16 can be used to cooperate with the head mold to facilitate position adjustment. At the same time, the bending design of the third support member 16 can be used to avoid the movement of the first column 51 and the second column 52, thereby avoiding the third support member 16 from interfering with the movement of the two columns, thereby ensuring the reliability and safety of the adjustment mechanism. In one embodiment, a pressure sensor 19 may be embedded in the right-angle region of the L-shaped structure. The pressure sensor 19 can detect the pressure of the matching upper mold, ie, the clamping force.

The first sliding member 511 and the second sliding member 521 are both located on the outside and can respectively cooperate with the corresponding left head mold and right head mold.

[0121] In one embodiment, a pressure sensor 19 may be connected to the first column 51 and abutted against the first sliding member 511. For example, the pressure sensor 19 may be embedded in the first column 51 and abutted against the first sliding member 511, thereby forming a pressure transmission path from the left head mold to the first sliding member 511 to the pressure sensor 19, so that the pressure sensor 19 can detect the pressure of the mating left head mold, that is, the clamping force.

[0122] Similarly, a pressure sensor 19 may be connected to the second column 52 and abutted against the second sliding member 521. For example, the pressure sensor 19 may be embedded in the second column 52 and abutted against the second sliding member 521, thereby forming a pressure transmission path from the right head mold to the second sliding member 521 to the pressure sensor 19, so that the pressure sensor 19 can detect the pressure of the mating right head mold, that is, the clamping force.

[0123] The first sliding member 511 and the second sliding member 521 may respectively adopt standardized interfaces, such as dovetail grooves, quick-release buckles, or threaded holes, so as to support the rapid replacement of headforms 100 of different specifications.

[0124] Optionally, a pressure sensor 19 is further included, and the first support member 4 and / or the second support member 5 is connected to the pressure sensor 19.

[0125] like Figure 8 As shown, the corresponding arrangement of the pressure sensors 19 on the first support member 4 and the second support member 5 enables the pressure sensors 19 to measure the supporting force of the corresponding support members, that is, the pressure or clamping force of the matching head mold 100 in real time.

[0126] Furthermore, the pressure sensor 19 can also cooperate with the corresponding detection element to achieve closed-loop control of the support force. This can not only detect the overall clamping force of the head mold 100, but also obtain the distribution of the clamping force in different areas to simulate the wearing comfort of the human head.

[0127] The head mold assembly and the adjustment mechanism include a plurality of head molds 100 , and the first support member 4 and the second support member 5 are respectively matched with the corresponding head molds 100 .

[0128] When the first driving member 2 and the second driving member 3 of the adjustment mechanism are in motion, they can respectively drive the first supporting member 4 and the second supporting member 5 to move, thereby enabling adjustment of the corresponding position of the head mold 100 .

[0129] Optionally, the head mold assembly includes four head molds 100, namely, a front head mold, a left head mold, a right head mold and an upper head mold. The driving direction of the first driving member 2 is the X direction, the driving direction of the second driving member 3 is the Y direction, and the driving direction of the third driving member 15 is the Z direction, so that the first support member 4 can cooperate with the front head mold, the second support member 5 can cooperate with the left head mold and the right head mold, and the third support member 16 can cooperate with the upper head mold.

In this way, the three drivers can achieve independent adjustment of the headform 100 in multiple directions (X, Y, and Z) to suit different wearing requirements.

[0131] Furthermore, the communication connections between the first detection member 6 and the first drive member 2, the second detection member 7 and the second drive member 3, and the third detection member 17 and the third drive member 15 also enable intelligent multi-directional control of the adjustment mechanism in X, Y, and Z directions. The operator can preset the target position parameters of the headform 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding drive members based on the displacement information fed back by the detection members, enabling automated adjustment of the position of the headform 100. This intelligent control approach significantly simplifies the operational process, reduces manual intervention, and improves operational efficiency and accuracy.

[0132] Optionally, each head mold 100 is provided with an assembly portion 1001 , and the first support member 4 and the second support member 5 are respectively matched with the corresponding assembly portion 1001 .

[0133] like Figure 2 and Figure 9 As shown, an assembly portion 1001 can be provided on the head mold 100, and the assembly portion 1001 can be a groove, and the support member has a protrusion, and the protrusion is adapted to the corresponding groove; the assembly portion 1001 can also be a protrusion, and the support member has a groove portion, and the protrusion is adapted to the corresponding groove portion, so that the support member can form a snap fit with the corresponding head mold 100, which can realize convenient and reliable assembly of the support member and the head mold 100 while facilitating the disassembly and replacement of the head mold 100, thereby realizing the clamping force measurement of different head molds 100.

[0134] Optionally, the first support member 4 and / or the second support member 5 has a sliding portion, the assembly portion 1001 has a slide rail, and the sliding portion is slidably connected to the corresponding slide rail; And / or, the adjustment mechanism further includes a pressure sensor 19 , and the first support member 4 and / or the second support member 5 is connected to the pressure sensor 19 .

[0135] like Figure 10 As shown, the assembly portion 1001 of the head mold 100 may be provided with a slide rail, and the support member may have a sliding portion that is adapted to the corresponding slide rail and can be slidably assembled along the slide rail to facilitate assembly and disassembly of the support member and the head mold 100.

[0136] like Figure 8 and Figure 11 As shown, the corresponding arrangement of the pressure sensors 19 on the first support member 4 and the second support member 5 enables the pressure sensors 19 to measure the supporting force of the corresponding support members, that is, the pressure or clamping force of the matching head mold 100 in real time.

[0137] Furthermore, the pressure sensor 19 can also cooperate with a corresponding detection element to achieve closed-loop control of the support force. In this way, not only can the overall clamping force of the head mold 100 be detected, but the distribution of the clamping force in different areas can also be obtained to simulate the wearing comfort of the human head.
