The head-mounted device to be measured is then worn on the head mold component, and a measuring device is used to measure the clamping force exerted by the head-mounted device on the head mold component.

[0004] However, since head-mounted products need to meet the wearing needs of different users, their sizes vary, resulting in different sizes of the corresponding head mold components. This requires the measuring device to also meet the measurement needs of head-mounted products of different sizes. Utility Model Content

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0041] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0043] This utility model provides an adjustment mechanism for a head mold assembly, which includes multiple head molds 100, such as two, three, four or even more.

[0044] like Figures 1 to 3 As shown, the adjustment mechanism of the head mold assembly provided in this embodiment of the present invention includes:

[0045] Base 1;

[0046] A first driving member 2 and a second driving member 3 are respectively disposed on the base 1;

[0047] The first support member 4 and the second support member 5 are configured to cooperate with the corresponding head mold 100 respectively.

[0048] The driving end of the first driving member 2 is connected to the first support member 4 in a transmission manner so as to drive the first support member 4 to move along the first direction;

[0049] The second support member 5 includes a first column 51 and a second column 52 arranged in the same row along the second direction, and the first column 51 and the second column 52 are respectively connected to the driving end of the second driving member 3;

[0050] Driven by the second driving member 3, the first column 51 and the second column 52 can move in opposite directions along the second direction, and there is an angle between the first direction and the second direction.

[0051] Specifically, the base 1, serving as the mounting foundation for the entire adjustment mechanism, can be made of high-strength, high-rigidity metal materials, such as aluminum alloy or stainless steel. The base 1 is typically a rectangular flat plate structure with a precision-machined surface to ensure flatness, thus providing stable support and a mounting reference. Mounting holes can be provided at the four corners of the base 1 for fixing the entire adjustment mechanism to a work platform or other equipment.

[0052] The first driving component 2 and the second driving component 3 can be servo motors or cylinders, and can be fixed to corresponding positions on the base 1 by bolts. Figure 2 As shown, slots can be cut at corresponding positions on the base 1, and the first drive component 2 and the second drive component 3 can be embedded in the corresponding slots. This facilitates the assembly of the drive components and helps improve assembly accuracy. At the same time, the slots can also form a relatively independent area on the base, so that the drive components embedded therein can operate more stably.

[0053] In this design, the driving direction of the first driving component 2 is designated as the first direction, and the driving direction of the second driving component 3 is designated as the second direction. This creates an angle between the first and second directions, meaning their driving directions are not identical. This allows for independent driving and adjustment of multiple head models 100 in two different directions, facilitating the wearing requirements of head model components of different sizes and enabling the measurement of clamping forces for headwear products of varying sizes. For example, in human head model simulation experiments in the medical field, the position of the head model 100 in both the horizontal and vertical directions can be precisely adjusted according to different experimental requirements, simulating head postures in various real-world scenarios and providing more accurate data support for the experiments. In fields such as industrial design or virtual reality, the angle and position of the head model 100 can also be easily adjusted to meet different display or interactive needs.

[0054] In one embodiment, the first direction can be set as the horizontal X-axis direction and the second direction as the horizontal Y-axis direction, so that there is a 90° angle between the driving directions of the two driving members, so as to enable independent adjustment of the head mold 100 in two mutually perpendicular directions.

[0055] In one embodiment, the first drive unit 2 and the second drive unit 3 can be connected to an external control system via a controller. The control system can send control signals to the first drive unit 2 and the second drive unit 3 according to a preset program or received instructions, and control their start, stop, forward and reverse rotation, as well as their running speed and displacement, respectively.

[0056] like Figures 1 to 3 As shown, the first support member 4 and the second support member 5 can be made of a metal material with good rigidity. Rubber pads can be provided on the surfaces of the first support member 4 and the second support member 5 that contact the corresponding head mold 100. The rubber pads have a certain elasticity and friction to better fit with the head mold 100, preventing the head mold 100 from sliding during adjustment, and also serving to cushion and protect the head mold 100.

[0057] In one embodiment, the drive end of the first drive member 2 can be connected to the first support member 4 via a coupling. The coupling is an elastic pin coupling, which has a certain ability to compensate for the relative displacement of the two shafts, so as to smoothly transmit the power of the first drive member 2 to the first support member 4, reduce the impact and vibration during the transmission process, and avoid problems such as head mold 100 position deviation or adjustment loss due to unstable transmission. Similarly, the drive end of the second drive member 3 can also be connected to the second support member 5 via an elastic pin coupling, so as to smoothly transmit the power of the second drive member 3 to the second support member 5.

[0058] Since the first driving component 2 and the second driving component 3 independently drive the first support component 4 and the second support component 5 respectively, the head mold 100 can be adjusted individually in different directions during the adjustment process, without being affected by other directions. This independent adjustment method also increases the flexibility of adjustment. Operators can adjust the position of the head mold 100 in one direction first, and then adjust the position in another direction, or make fine adjustments in two directions at the same time, so as to quickly and accurately achieve the ideal posture of the head mold 100.

[0059] The first support member 4 and the second support member 5 respectively engage with their corresponding head molds 100. Specifically, the head mold 100 has grooves or slots that match the shapes of the first support member 4 and the second support member 5. The first support member 4 and the second support member 5 are inserted into the grooves or slots of the head mold 100 to achieve a stable connection. When the first drive member 2 and the second drive member 3 are activated, they respectively drive the first support member 4 and the second support member 5 to move in a predetermined direction, thereby adjusting the position of the head mold 100.

[0060] This makes the adjustment mechanism highly versatile. Head molds 100 of different specifications and shapes can be adapted to the adjustment mechanism by designing corresponding support components. For example, in the medical field, corresponding first support component 4 and second support component 5 can be customized according to the size and shape of the head mold 100 for patients of different age groups, enabling the adjustment mechanism to be widely used for adjusting various types of head molds 100, including those for children and adults. In the field of industrial design, the support components can also be replaced to adapt to product head molds 100 of different shapes and sizes, improving the applicability and efficiency of the adjustment mechanism.

[0061] like Figures 1 to 3 As shown, the second support member 5 may include a first column 51 and a second column 52 arranged in the same row at intervals along a second direction, such as the Y direction in the figure. The first column 51 and the second column 52 are respectively connected to the driving end of the second driving member 3. One of the first column 51 and the second column 52 can cooperate with the left head mold, and the other of the first column 51 and the second column 52 can cooperate with the right head mold, so as to realize the position adjustment of the left and right head molds.

[0062] Driven by the second driving component 3, the first column 51 and the second column 52 can move in opposite directions along the second direction, such as the Y direction in the figure, that is, drive the first column 51 and the second column 52 to move closer to each other or further away from each other, thereby enabling convenient adjustment of the position of the left and right head molds.

[0063] In addition, depending on the actual adjustment needs, the first column 51 and the second column 52 can be specifically arranged so that the second driving member 3 can drive the first column 51 and the second column 52 to move closer to each other or further away from each other, so as to adjust the position of the two opposing head molds 100.

[0064] Optionally, the first direction is perpendicular to the second direction.

[0065] Specifically, the first direction and the second direction can be set to the X direction and the Y direction respectively, so as to realize the horizontal XY direction position adjustment of the head mold 100; or the first direction and the second direction can be set to the X direction and the Z direction respectively, so as to realize the XZ direction position adjustment of the head mold 100; or the first direction and the second direction can be set to the Y direction and the Z direction respectively, so as to realize the YZ direction position adjustment of the head mold 100, thereby meeting different adjustment needs.

[0066] Furthermore, setting the first direction to be perpendicular to the second direction facilitates the arrangement of related structures, thereby reducing the assembly difficulty of the adjustment mechanism.

[0067] Optionally, it also includes a second transmission member 9, the driving end of the second driving member 3 is connected to the second transmission member 9, and the first column 51 and the second column 52 are respectively connected to the second transmission member 9.

[0068] Specifically, the second driving component 3 can be a servo motor, and the second transmission component 9 is a slide rod connected to the drive end of the servo motor. Under the drive of the servo motor, the slide rod can generate precise linear motion and drive the second support component 5 on it to move to a preset position.

[0069] 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, the second column 52 has a second internal thread, the first internal thread is threaded to the first external thread, the second internal thread is threaded to the second external thread, and the first external thread and the second external thread are respectively threaded together, and the first external thread and the second external thread have opposite thread directions.

[0070] Specifically, the first external thread and the second external thread on the second transmission component 9 can be set to have the same pitch and opposite directions of rotation, so that under the drive of the second driving component 3, the first column 51 and the second column 52 can produce displacements in opposite directions, that is, generate reverse synchronous movements, so as to realize the synchronous position adjustment of the left and right head molds.

[0071] In this way, the second transmission component 9 with reverse threads can achieve bidirectional drive function without the need for additional anti-loosening nuts, locking washers and other components, which helps to reduce the production cost and assembly difficulty of the adjustment mechanism.

[0072] 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 segment and a second segment arranged at intervals. The driving end of the first sub-driving member is connected to the first segment, and the driving end of the second sub-driving member is connected to the second segment. The first column 51 is connected to the first segment, and the second column 52 is connected to the second segment. The driving direction of the first sub-driving member is opposite to that of the second sub-driving member, so that the first column 51 and the second column 52 can be driven to move closer to each other or further away from each other by the first sub-driving member and the second sub-driving member respectively, thereby also realizing the independent position adjustment of the left and right head molds.

[0073] In this way, two sub-drive components can be used to achieve independent drive of the two pillars, so that the positions of the left head mold and the right head mold can be adjusted separately to adapt to different wearing needs.

[0074] Optionally, the system further includes a third driving member 15 and a third supporting member 16. The third supporting member 16 is configured to cooperate with the corresponding head mold 100. The third driving member 15 is disposed on the base 1, and the driving end of the third driving member 15 is connected to the third supporting member 16 to drive the third supporting member 16 to move along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. In this way, the position adjustment of the head mold assembly in three directions can be realized.

[0075] Optionally, the head mold assembly includes a front head mold, a left head mold, a right head mold, and an upper head mold, with the first direction being the X direction, the second direction being the Y direction, and the third direction being the Z direction, such 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.

[0076] like Figures 1 to 3 As shown, driven by the first driving component 2, the first support component 4 can move along the X direction and adjust the position of the corresponding front head mold; driven by the second driving component 3, the second support component 5 can move along the Y direction and adjust the position of the corresponding left and right head molds; driven by the third driving component 15, the third support component 16 can move along the Z direction and adjust the position of the corresponding upper head mold. Thus, the head mold 100XYZ can be independently adjusted in multiple directions using three driving components to adapt to different wearing needs.

[0077] Optionally, the third support member 16 has an L-shaped structure.

[0078] like Figures 1 to 3As shown, the cross-section of the third support member 16 along the XZ plane is L-shaped. This allows the L-shaped third support member 16 to be used in conjunction with the head mold for easy position adjustment, while also allowing the bending design of the third support member 16 to avoid the movement of the first column 51 and the second column 52, thus preventing the third support member 16 from interfering with the movement of the two columns and ensuring the reliability and safety of the adjustment mechanism.

[0079] In one embodiment, a pressure sensor 19 can also be embedded in the right-angle region of the L-shaped structure. The pressure sensor 19 can detect the pressure of the mating upper mold, i.e., the clamping force.

[0080] Optionally, the projection of the third support member 16 in the XY plane does not overlap with the movement path of the first support member 4 and the movement path of the second support member 5, which can also avoid the third support member 16 interfering with the movement of the two supports, thereby ensuring the reliability and safety of the adjustment mechanism.

[0081] Optionally, it also includes a first detection element 6 and a second detection element 7. The first detection element 6 is configured to detect the displacement value of the first support 4, and the second detection element 7 is configured to detect the displacement value of the second support 5. The first detection element 6 is communicatively connected to the first drive element 2, and the second detection element 7 is communicatively connected to the second drive element 3.

[0082] like Figure 1 As shown, the first detection element 6 and the second detection element 7 can be selected from displacement sensors such as laser type, photoelectric type, and Hall type. These displacement sensors can accurately measure the displacement of the corresponding support and convert the displacement signal into an electrical signal and output it to the controller.

[0083] Furthermore, the first detection element 6 and the second detection element 7 are respectively connected to their corresponding driving elements via signal lines or wireless communication. During the adjustment process, the first detection element 6 can detect the displacement value of the first support element 4 in real time and convert the displacement signal into an electrical signal, which is then sent to the control circuit of the first driving element 2; the second detection element 7 can detect the displacement value of the second support element 5 in real time and send the displacement signal to the control circuit of the second driving element 3. The control circuits of the first driving element 2 and the second driving element 3 compare the received displacement signal with the preset target displacement value. If there is a deviation, the operating state of the corresponding driving element is adjusted until the displacement of the first support element 4 and the second support element 5 reaches the target value, thereby achieving precise adjustment of the head mold 100 position.

[0084] Therefore, through this closed-loop feedback control system, the driving component can adjust its operating state in a timely manner based on the detected deviation between the actual displacement of the corresponding support component and the target displacement, such as changing the rotation speed, direction, or stopping operation, thereby achieving precise control of the head mold 100 position. Compared with traditional open-loop control adjustment mechanisms, the adjustment mechanism of this invention can greatly improve the adjustment accuracy, control the displacement error within a very small range, and ensure that the head mold 100 accurately reaches the preset position.

[0085] Furthermore, the communication connection between the first detection element 6 and the first driving element 2, and between the second detection element 7 and the second driving element 3, enables the adjustment mechanism to achieve intelligent control. Operators can preset the target position parameters of the head mold 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding driving elements based on the displacement information fed back by the detection elements, thus achieving automated adjustment of the head mold 100's position. This intelligent control method greatly simplifies the operation process, reduces manual intervention, and improves operational efficiency and accuracy.

[0086] Optionally, it further includes a first transmission member 8, wherein the driving end of the first driving member 2 is connected to the first transmission member 8, and the first support member 4 is connected to the first transmission member 8. Figures 1 to 3 As shown, the first driving component 2 is a servo motor, and the first transmission component 8 is a slide rod connected to the driving end of the servo motor. Under the drive of the servo motor, the slide rod can generate precise linear motion and drive the support component on it to move to a preset position.

[0087] Optionally, it also includes a control element 10, which is disposed on the base 1, and the first detection element 6, the second detection element 7, the first driving element 2 and the second driving element 3 are respectively communicatively connected to the control element 10.

[0088] Specifically, the first detection element 6 and the second detection element 7 can detect the displacement values ​​of the first support element 4 and the second support element 5 in real time and feed this data back to the control element 10. The control element 10, i.e., the controller, compares the feedback displacement value with the preset target displacement value in real time. If a deviation is found, it will adjust the operating state of the corresponding drive element, such as changing the speed or direction, to eliminate the deviation and achieve closed-loop feedback precise control. This control method can correct errors in the adjustment process in a timely manner, keeping the displacement error of the head mold 100 within a very small range, thereby meeting the high-precision position requirements of the head mold 100 in medical, scientific research and other fields.

[0089] The adjustment of the head model 100 often involves parameters in multiple directions, such as horizontal and vertical displacement. The control unit 10 can simultaneously process displacement information from the first detection unit 6 and the second detection unit 7 in multiple directions, and precisely control the actions of the first drive unit 2 and the second drive unit 3 according to a preset collaborative adjustment algorithm, thereby achieving precise collaborative 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 movements, it is necessary to adjust the position and angle of the head model 100 in multiple directions simultaneously. The control unit 10 can precisely control the corresponding drive units based on the user's motion data, making the movement of the head model 100 highly consistent with the user's actual movement, thus enhancing the realism of the virtual reality experience.

[0090] Optionally, a third detection element 17 is also included, which is configured to detect the displacement value of the third support 16, and the third detection element 17 is communicatively connected to the third drive element 15.

[0091] like Figures 1 to 3 As shown, the third detection element 17 can be a displacement sensor such as a laser type, photoelectric type, or Hall effect type. These displacement sensors can accurately measure the displacement of the third support element 16 and convert the displacement signal into an electrical signal to be output to the controller so as to adjust the driving state of the third drive element 15.

[0092] like Figures 1 to 3 As shown, it also includes a third transmission component 18, a third connecting component 20, a third reflector 21, and a bracket 22. First, the bracket 22 is connected to the base 1 along the Z direction. Then, the third transmission component 18 is connected to the bracket 22. After that, the third connecting component 20 is connected to the third transmission component 18. Finally, the third support component 16 and the third reflector 21 are respectively connected to two adjacent sides of the third connecting component 20, and the third reflector 21 is oriented towards the third detection component 17 so that the third detection component 17 can detect the displacement value of the third support component 16.

[0093] Furthermore, the communication connections between the first detection element 6 and the first driving element 2, the second detection element 7 and the second driving element 3, and the third detection element 17 and the third driving element 15 enable the adjustment mechanism to achieve intelligent control in multiple XYZ directions. Operators can preset the target position parameters of the head mold 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding driving elements based on the displacement information fed back by the detection elements, thus achieving automated adjustment of the head mold 100's position. This intelligent control method greatly simplifies the operation process, reduces manual intervention, and improves operational efficiency and accuracy.

[0094] Optionally, it also includes a first reflector 11, which is connected to the first transmission member 8 or the first support member 4, and the first detection member 6 is a first laser sensor, which is disposed on the base 1 and faces the first reflector 11.

[0095] And / or, it also includes a second reflector 12, which is connected to the second transmission member 9 or the second support member 5, and the second detection member 7 is a second laser sensor, which is disposed on the base 1 and faces the second reflector 12.

[0096] like Figure 1 As shown, the first reflector 11 can be a reflector plate. The first reflector 11 is connected to the first transmission member 8 or the first support member 4, so that the first reflector 11 can move together with the first support member 4. During the movement of the first reflector 11 together with the first support member 4, the first laser sensor can emit laser light towards the first reflector 11 and receive the laser light reflected back from the first reflector 11, thereby obtaining the real-time displacement of the first support member 4, so as to adjust the driving state of the first drive member 2.

[0097] Similarly, the second reflector 12 can also be a reflector plate. The second reflector 12 is connected to the second transmission member 9 or the second support member 5, so that the second reflector 12 can move together with the second support member 5. During the movement of the second reflector 12 together with the second support member 5, the second laser sensor can emit laser light towards the second reflector 12 and receive the laser light reflected back from the second reflector 12, thereby obtaining the real-time displacement of the second support member 5, so as to adjust the driving state of the second drive member 3.

[0098] Optionally, the laser sensor and the corresponding reflector are coaxially arranged;

[0099] Alternatively, the angle between the axes of the laser sensor and the corresponding reflector shall not exceed 45 degrees.

[0100] 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 sensor and the corresponding reflector are completely coaxial, so that the laser emission path and the laser reception path are completely coincident, thereby eliminating the measurement dead angle caused by the laser sensor due to the optical path offset, thereby improving the detection accuracy and real-time response capability of the laser sensor.

[0101] In one embodiment, the axes of the first laser sensor and the first reflector 11 may be set to form an angle, and the axes of the second laser sensor and the second reflector 12 may also form an angle, meaning that the laser sensors and their corresponding reflectors are not coaxial. On the one hand, this can adapt to the complex spatial layout inside the adjustment mechanism, facilitating the 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 sensor through a special coating process.

[0102] Optionally, it also includes a first connector 13, which is disposed on the first transmission member 8, and the first support member 4 and the first reflector 11 are respectively connected to the first connector 13;

[0103] And / or, it also includes a second connector 14, which is disposed on the second transmission member 9, and the second support member 5 and the second reflector member 12 are respectively connected to the second connector 14.

[0104] like Figure 2 As shown, the first connecting member 13 can be a connecting plate. After it is placed on the first transmission member 8, the first support member 4 and the first reflector 11 are placed on it. This can facilitate the installation of the first support member 4 and the first reflector 11, and 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.

[0105] Furthermore, the driving force transmission path formed by the first driving component 2 - first transmission component 8 - first connecting component 13 - first support component 4 and first reflector 11 can also buffer the driving force output by the first driving component 2, avoiding the risk caused by the driving force acting directly on the first support component 4 and the first reflector 11.

[0106] Similarly, the second connector 14 can also be a connecting plate, which is placed on the second transmission member 9, and then the second support member 5 and the second reflector 12 are placed on it. This can facilitate the installation of the second support member 5 and the second reflector 12, while also avoiding friction and wear between the second support member 5, the second reflector 12 and the second transmission member 9, thus helping to ensure the normal operation of the second support member 5 and the second reflector 12.

[0107] Furthermore, 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 risk caused by the driving force directly acting on the second support member 5 and the second reflector 12.

[0108] Optionally, the first support member 4 and the first reflector 11 are respectively connected to two adjacent sides of the first connector 13, and the extending direction of the first support member 4 is perpendicular to the driving direction of the first drive member 2.

[0109] like Figure 2 As shown, the first support member 4 and the first reflector 11 are respectively connected to two adjacent sides of the first connector 13 to make full use of the connection space of the first connector 13 and to avoid interference between the first support member 4 and the first reflector 11 during movement. The extension direction of the first support member 4 is the Z direction, and the driving direction of the first drive member 2 is the X direction, so as to use the first support member 4 to adjust the position of the mating head mold.

[0110] Optionally, the second support member 5 and the second reflector 12 are respectively connected to two adjacent sides of the second connector 14, and the extending direction of the second support member 5 is perpendicular to the driving direction of the second drive member 3.

[0111] like Figures 1 to 3 As shown, the second support member 5 and the second reflector 12 are respectively connected to the two adjacent sides of the second connector 14 to make full use of the connection space of the second connector 14 and to avoid interference between the second support member 5 and the second reflector 12 during movement. The extension direction of the second support member 5 is the Z direction, and the driving direction of the second drive member 3 is the Y direction, so as to use the second support member 5 to adjust the position of the mating left and right head molds.

[0112] Optionally, the first detection element 6 and / or the second detection element 7 are pull-wire rangefinders, which are mounted on the base 1, and the pull wire of the pull-wire rangefinder is connected to the corresponding transmission element or the corresponding support element.

[0113] In one embodiment, the first detection element 6 can be set as a first pull-wire rangefinder. The first pull-wire rangefinder is placed at the corresponding position of the base 1, and its pull rope is connected to the first support element 4 or the first transmission element 8. This allows the first pull-wire rangefinder to detect the displacement of the first support element 4 in real time as the first support element 4 moves together with the first transmission element 8, thereby facilitating the adjustment of the driving state of the first drive element 2.

[0114] Similarly, the second detection element 7 can be set as a second pull-wire rangefinder. The second pull-wire rangefinder is placed at the corresponding position of the base 1, and its pull rope is connected to the second support element 5 or the second transmission element 9. This allows the second pull-wire rangefinder to detect the displacement of the second support element 5 in real time as the second support element 5 moves together with the second transmission element 9, thereby facilitating the adjustment of the driving state of the second drive element 3.

[0115] Optionally, the first detection element 6 and / or the second detection element 7 can also be linear displacement sensors. The linear displacement sensors are placed on the corresponding transmission element or the corresponding support element so that the linear displacement sensors can accurately measure the linear displacement of the corresponding support element and convert the displacement signal into an electrical signal output to adjust the driving state of the corresponding driving element.

[0116] Optionally, the side of the first column 51 away from the second column 52 has a first sliding member 511, and the side of the second column 52 away from the first column 51 has a second sliding member 521. The first sliding member 511 is used to cooperate with the left head mold, and the second sliding member 521 is used to cooperate with the right head mold.

[0117] like Figure 3 As shown, the side of the first column 51 away from the second column 52 can be partially excavated first, and then the first sliding member 511 can be connected to reliably install the first sliding member 511 onto the first column 51; similarly, the side of the second column 52 away from the first column 51 can be partially excavated first, and then the second sliding member 521 can be connected to reliably install the second sliding member 521 onto the second column 52.

[0118] Thus, the first column 51 is connected to the first sliding member 511, and the second column 52 is connected to the second sliding member 521. The first sliding member 511 and the second sliding member 521 are both located on the outside and can cooperate with the corresponding left head mold and right head mold respectively.

[0119] In one embodiment, a pressure sensor 19 can also be connected to the first column 51 and abut against the first slider 511. For example, the pressure sensor 19 can be embedded in the first column 51 and abut against the first slider 511 to form a pressure transmission path of left head mold - first slider 511 - pressure sensor 19, so that the pressure sensor 19 can detect the pressure of the mating left head mold, i.e., the clamping force.

[0120] Similarly, a pressure sensor 19 can be connected to the second column 52 and abut against the second slider 521. For example, the pressure sensor 19 can be embedded in the second column 52 and abut against the second slider 521 to form a pressure transmission path of right head mold - second slider 521 - pressure sensor 19, so that the pressure sensor 19 can detect the pressure of the mating right head mold, i.e., the clamping force.

[0121] The first sliding member 511 and the second sliding member 521 can each adopt standardized interfaces, such as dovetail grooves, quick-release buckles or threaded holes, to support the quick replacement of head molds 100 of different specifications.

[0122] Optionally, it also includes a pressure sensor 19, which is connected to the first support 4 and / or the second support 5.

[0123] like Figure 4 As shown, the corresponding arrangement of 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 member in real time, that is, the pressure or clamping force of the head mold 100.

[0124] Furthermore, the pressure sensor 19 can cooperate with the corresponding detection element to achieve closed-loop control of the support force. It can not only detect the overall clamping force of the head mold 100, but also obtain the distribution of clamping force in different areas, so as to simulate the comfort of wearing a human head.

[0125] According to another aspect of the present invention, a clamping force measuring device is provided, including a head mold assembly and an adjustment mechanism for the head mold assembly. The head mold assembly includes a plurality of head molds 100, and the first support member 4 and the second support member 5 respectively cooperate with the corresponding head molds 100.

[0126] When the first drive member 2 and the second drive member 3 of the adjustment mechanism are activated, they respectively drive the first support member 4 and the second support member 5 to move, thereby enabling the adjustment of the position of the corresponding head mold 100. This makes the clamping force measuring device highly versatile. Head molds 100 of different specifications and shapes can be adapted to the clamping force measuring device by designing corresponding support members.

[0127] Optionally, the head mold assembly includes four head molds 100: a front head mold, a left head mold, a right head mold, and an upper head mold. The first driving member 2 drives in the X direction, the second driving member 3 drives in the Y direction, and the third driving member 15 drives in 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.

[0128] like Figures 1 to 3 ,as well as Figure 8 and Figure 9 As shown, driven by the first driving component 2, the first support component 4 can move along the X direction and adjust the position of the corresponding front head mold; driven by the second driving component 3, the second support component 5 can move along the Y direction and adjust the position of the corresponding left and right head molds; driven by the third driving component 15, the third support component 16 can move along the Z direction and adjust the position of the corresponding upper head mold. Thus, the head mold 100XYZ can be independently adjusted in multiple directions using three driving components to adapt to different wearing needs.

[0129] Furthermore, the communication connections between the first detection element 6 and the first driving element 2, the second detection element 7 and the second driving element 3, and the third detection element 17 and the third driving element 15 enable the adjustment mechanism to achieve intelligent control in multiple XYZ directions. Operators can preset the target position parameters of the head mold 100 through an external control system. The adjustment mechanism automatically adjusts the operation of the corresponding driving elements based on the displacement information fed back by the detection elements, thus achieving automated adjustment of the head mold 100's position. This intelligent control method greatly simplifies the operation process, reduces manual intervention, and improves operational efficiency and accuracy.

[0130] Optionally, each of the head molds 100 is provided with an assembly part 1001, and the first support member 4 and the second support member 5 respectively cooperate with the corresponding assembly part 1001.

[0131] like Figure 5 and Figure 6 As shown, an assembly part 1001 can be provided on the head mold 100. The assembly part 1001 can be a groove, and the support member has a protrusion that matches the corresponding groove. Alternatively, the assembly part 1001 can be a protrusion, and the support member has a groove that matches the corresponding groove, so that the support member can form a snap-fit ​​with the corresponding head mold 100. This allows for convenient and reliable assembly of the support member and the head mold 100, while also facilitating the disassembly and replacement of the head mold 100. Thus, the clamping force measuring device can be used to measure the clamping force of different head molds 100.

[0132] Optionally, the first support member 4 and / or the second support member 5 have a sliding portion, and the assembly portion 1001 has a slide rail, the sliding portion being slidably connected to the corresponding slide rail;

[0133] And / or, the adjustment mechanism further includes a pressure sensor 19, and the pressure sensor 19 is connected to the first support 4 and / or the second support 5.

[0134] like Figure 7 As shown, the assembly part 1001 of the head mold 100 can be provided with a slide rail, and the support member has a sliding part. The sliding part is adapted to the corresponding slide rail and can slide along the slide rail to facilitate the assembly and disassembly of the support member and the head mold 100.

[0135] like Figure 4 and Figure 8 As shown, the corresponding arrangement of 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 member in real time, that is, the pressure or clamping force of the head mold 100.

[0136] Furthermore, the pressure sensor 19 can also cooperate with the corresponding detection element to achieve closed-loop control of the support force. In this way, the clamping force measuring device can not only detect the overall clamping force of the head mold 100, but also obtain the distribution of clamping force in different areas, so as to simulate the comfort of wearing a human head.

[0137] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
