Description

Technical Field

[0001] This utility model relates to the field of assistive medical device technology, and in particular to an assistive device for monitoring facial muscle movement. Background Technology

[0002] In the field of medical rehabilitation, patients with orofacial muscle abnormalities often need to undergo standardized myofunctional training according to medical advice to achieve good rehabilitation results. During the rehabilitation process, doctors generally use large monitoring devices provided by the hospital to assess the effectiveness of the rehabilitation training. These devices are large, limiting their use and making them inconvenient for patients to carry with them.

[0003] In addition, existing monitoring devices involve mounting sensors that monitor muscle movement on a mechanical structure worn on the head, with the sensors in direct contact with the facial skin. For example, strain gauges are attached to the skin surface to sense deformation caused by movement training. However, this not only makes the sensors prone to damage, but also results in less than ideal monitoring sensitivity.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that this section is intended to provide background or context for the technical solutions of the invention as set forth in the claims. The description herein does not imply acceptance as prior art simply because it is included in this section. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary device for monitoring facial muscle movement, thereby overcoming one or more problems caused by the limitations and defects of related technologies to a certain extent.

[0007] According to this utility model, an auxiliary device for monitoring facial muscle movement is provided, the auxiliary device comprising:

[0008] A headgear designed to be worn on a user's head;

[0009] The measuring mechanism includes a measuring arm, a sensor, and a trigger rebound assembly. The measuring arm is adjustablely connected to the side of the head-mounted mechanism, the sensor is disposed inside the measuring arm, and the trigger rebound assembly is spring-loaded onto the measuring arm.

[0010] The trigger rebound assembly includes a contact and a pressure member disposed on the contact. The contact protrudes from the measuring arm and is used to conform to the face. The pressure member is located between the contact and the sensor and is used to press the sensor. The surface area of ​​the pressure member facing the sensor is smaller than the surface area of ​​the contact on the side away from the pressure member.

[0011] The technical solution provided by this utility model can include the following beneficial effects:

[0012] In this invention, the aforementioned auxiliary device for monitoring facial muscle movement offers several advantages. First, the measuring arm of the auxiliary device can be flexibly adjusted according to rehabilitation training requirements. Furthermore, the measuring arm and trigger rebound assembly of the auxiliary device can shield the sensor, preventing it from being exposed and protecting it. Second, by designing the trigger rebound assembly as a contact element and a pressure element, and by designing the surface area of ​​the pressure element facing the sensor to be smaller than the surface area of ​​the contact element away from the pressure element, a larger contact element can be used to conform to the user's face during rehabilitation training. This allows for more reliable reception of force changes caused by facial movements. The force changes from facial movements are then concentrated at the trigger point of the pressure element via the contact element, and subsequently transmitted to the sensor via the smaller pressure element. This enables the sensor to more sensitively detect pressure changes, improving monitoring sensitivity. Attached Figure Description

[0039] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] Furthermore, the accompanying drawings are merely illustrative diagrams of embodiments of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0041] This example embodiment first provides an auxiliary device for monitoring facial muscle movements. (Reference) Figure 1 As shown, the auxiliary device includes a head-mounted device 100 and a measuring mechanism. The head-mounted device 100 is worn on the user's head. The measuring mechanism includes a measuring arm, a sensor 400, and a trigger-rebound assembly 500. The measuring arm is adjustablely connected to the side of the head-mounted device 100, the sensor 400 is disposed inside the measuring arm, and the trigger-rebound assembly 500 is spring-loaded onto the measuring arm.

[0042] The trigger rebound assembly 500 includes a contact 510 and a pressing member 520 disposed on the contact 510. The contact 510 protrudes from the measuring arm and is used to conform to the face. The pressing member 520 is located between the contact 510 and the sensor 400 and is used to press the sensor 400. The pressing member 520 transmits the force on the contact 510 to the sensor 400, so that the sensor 400 can collect the pressure change caused by the movement of the jaw and face. The surface area of ​​the pressing member 520 facing the sensor 400 is smaller than the surface area of ​​the contact 510 away from the pressing member 520.

[0043] It should be noted that this embodiment does not limit the number of measuring arms included in the measuring mechanism; one or more can be provided, depending on the requirements of the measurement scenario. However, it should also be noted that each measuring arm is equipped with a sensor 400 and a trigger rebound assembly 500 for pressing the sensor 400. When the head-mounted mechanism 100 has one measuring arm, the motion state of one part of the jaw and face is collected through the monitoring device; when the head-mounted mechanism 100 has multiple measuring arms, the motion state of multiple parts of the jaw and face is collected through the monitoring device.

[0044] The aforementioned auxiliary device for facial muscle movement monitoring offers several advantages. First, the measuring arm of the device can be flexibly adjusted according to rehabilitation training requirements. Furthermore, the measuring arm and the trigger rebound assembly 500 can shield the sensor 400, preventing it from being exposed and protecting it. Second, the trigger rebound assembly 500 is designed with a contact element 510 and a pressure element 520. The surface area of ​​the pressure element 520 facing the sensor 400 is designed to be smaller than the surface area of ​​the contact element 510 away from the pressure element 520. During rehabilitation training, the larger contact element 510 can be used to conform to the user's face, more reliably receiving force changes caused by facial movements. The force changes from facial movements are concentrated at the trigger point, the pressure element 520, through the smaller pressure element 520, and then transmitted to the sensor 400. This allows the sensor 400 to more sensitively detect pressure changes, improving monitoring sensitivity.

[0045] It should be understood that, using the auxiliary device in this embodiment, when the user performs maxillofacial muscle training, the contact 510 of the trigger rebound assembly 500 contacts the maxillofacial region. As the maxillofacial muscles move, the contact 510 of the trigger rebound assembly 500 moves relative to the measuring arm, transmitting the force it receives to the pressure contact 520. The pressure contact 520 then presses against the sensor 400 within the measuring arm, allowing the sensor 400 to collect the pressure changes caused by the maxillofacial movement. It should be explained that the piezoelectric signal collected by the sensor 400 can be used to characterize information such as the speed and displacement of the maxillofacial movement; in this context, it can be understood as muscle training data.

[0046] It should be noted that the pressure member 520 is an elastic structure, or at least a part of the structure of the pressure member 520 is an elastic structure, so as to provide a rebound force to the contact member 510 in a direction away from the sensor 400 while pressing the sensor 400, and also to avoid damage to the sensor 400 when pressing the sensor 400.

[0047] It is also important to understand that a controller may be installed on the head-mounted device 100, and the sensor 400 is electrically connected to the controller. The controller sends the piezoelectric signals collected by the sensor 400 to the user terminal. The user terminal analyzes the user's maxillofacial movement state based on the received piezoelectric signals to obtain training results. This application does not involve the data processing methods of the user terminal, and will not be elaborated here. It is also important to understand that the user terminal can synchronously forward the training results and the muscle training data collected by the sensor 400 to the doctor's management terminal via a cloud server, so that the doctor can view the user's training status, understand the user's training status in a timely manner, provide a doctor-patient interaction channel, and improve treatment efficiency.

[0048] Below, we will refer to Figures 1 to 17 The various parts of the auxiliary device described above in this example embodiment will be described in more detail.

[0049] In one embodiment, reference Figure 1 and Figure 2 As shown, the head-mounted mechanism 100 includes a headband 110 and two ear loops 120. The headband 110 is a deformable metal piece, in the shape of a curved strip, for wearing on the user's head. The curved shape of the headband 110 can adapt to the user's head shape. The two ear loops 120 are respectively connected to two sides of the headband 110 for wearing on the user's ears. It should be noted that a measuring arm is adjustablely connected to the ear loops 120.

[0050] Optionally, the headband 110 may be made of memory steel wire, elastic steel sheet or elastic plastic sheet.

[0051] Additionally, refer to Figure 1 and Figure 2 As shown, a third mounting housing 130 is provided at the connection between the ear hook 120 and the headband 110 for assembling components such as the button 131, charging port 133, indicator light 132, controller, and connecting wires. For example, the main control compartment of the third mounting housing 130 is used to house the controller. This embodiment does not limit the specific installation position of components such as the button 131, battery, indicator light 132, and controller.

[0052] Furthermore, the auxiliary device also includes a power supply mounted on the head-mounted mechanism 100, which is electrically connected to the sensor 400 and is used to power the sensor 400.

[0053] It should be explained that the power supply in this embodiment can be installed in the battery compartment of the third mounting housing 130. This power supply is also electrically connected to components requiring power, such as the indicator light 132, to provide power to these components on the auxiliary device. Furthermore, the power supply installed on the head-mounted mechanism 100 is also electrically connected to the charging port 133 so that the power supply can be charged through the charging port 133.

[0054] In one embodiment, reference Figure 3 As shown, the measuring arm is provided with a rotating shaft 610 and a limiting member 620. The ear hook 120 of the head-mounted mechanism 100 is provided with a shaft hole 630 and a first limiting hole 640. The first limiting hole 640 extends circumferentially along the shaft hole 630. The rotating shaft 610 is rotatably connected to the shaft hole 630, and the limiting member 620 passes through the first limiting hole 640 and is limited within the first limiting hole 640 circumferentially along the shaft hole 630.

[0055] By cooperating with the aforementioned rotating shaft 610 and shaft hole 630, and with the limiting member 620 and the first limiting hole 640, it can adapt to the usage scenarios that require adjustment of the measuring arm relative to the head-mounted mechanism 100, so as to meet the user's rehabilitation training requirements.

[0056] It should be noted that the circumferential dimension of the first limiting hole 640 in the shaft hole 630 determines the adjustment angle of the measuring arm relative to the ear hook 120. It should also be noted that the dimension of the limiting member 620 is slightly larger than the dimension of the first limiting hole 640 along the radial direction of the shaft hole 630. This ensures that when the measuring arm needs to be adjusted relative to the head-mounted mechanism 100, external force can be used to rotate the rotating shaft 610 relative to the shaft hole 630. Furthermore, when the measuring arm does not need to be adjusted relative to the head-mounted mechanism 100, the limiting member 620 prevents the measuring arm from wobbling relative to the head-mounted mechanism 100.

[0057] Optionally, the measuring arm can be rotated and adjusted relative to the head-mounted mechanism 100 at an angle of 0° to 120°.

[0058] Optional, see reference Figure 4 As shown, the inner wall of the shaft hole 630 is provided with a plurality of protruding structures 631. The plurality of protruding structures 631 are evenly spaced along the circumferential direction of the shaft hole 630, and the plurality of protruding structures 631 are in frictional contact with the rotating shaft 610 rotatably assembled in the shaft hole 630. When it is necessary to adjust the measuring arm relative to the head-mounted mechanism 100, external force can be used to make the rotating shaft 610 rotate relative to the shaft hole 630. When it is not necessary to adjust the measuring arm relative to the head-mounted mechanism 100, the measuring arm will not wobble relative to the head-mounted mechanism 100.

[0059] In one embodiment, reference Figure 5 As shown, the pressure member 520 includes a probe 521 and an elastic member 522. One end of the probe 521 is connected to the contact member 510, and the other end is connected to the elastic member 522. The elastic member 522 is used to press the sensor 400 and provides a rebound force to the contact member 510 in a direction away from the sensor 400. When the contact member 510 is not subjected to external force, the elastic member 522 is in contact with the sensor 400; when the contact member 510 is subjected to external force, the elastic member 522 can press the sensor 400. By configuring the pressure element 520 into a structure of probe 521 and elastic element 522, the elastic element 522 presses the sensor 400, transmitting the force on the contact element 510 to the sensor 400. At the same time, the elastic element 522 can also provide a rebound force away from the sensor 400 to the contact element 510 and probe 521 of the trigger rebound assembly 500 in the axial direction of probe 521. In this way, during the movement of the jaw and face, the contact element 510 and probe 521 can move toward or away from the sensor 400 according to the movement of the jaw and face, so that the sensor 400 can collect the pressure changes caused by the movement of the jaw and face.

[0060] It should be noted that when the measuring arm is removed from the user's face, the contact 510 is no longer subjected to pressure. Under the elastic force of the elastic element 522, the contact 510 and the probe 521 will move away from the sensor 400 and reset, ending the current motion state acquisition work.

[0061] Optionally, in one embodiment, reference is made to... Figure 6 As shown, the elastic element 522 is a silicone head, which may include a cylindrical sleeve portion 5221 and an end cap portion 5222 connected to one end of the sleeve portion 5221. The sleeve portion 5221 is sleeved on the probe 521, and the end cap portion 5222 wraps around the end of the probe 521 facing the sensor 400. The outer surface of the end cap portion 5222 is a convex arc surface and is used to press the sensor 400. When the contact element 510 is not subjected to external force, the end cap portion 5222 is in contact with the sensor 400; when the contact element 510 is subjected to external force, the end cap portion 5222 can press the sensor 400 so that the sensor 400 can collect the pressure changes caused by the movement of the jaw and face.

[0062] Optional, see reference Figure 6As shown, when the elastic element 522 is a silicone tip, a spring 570 is sandwiched between the contact element 510 and the measuring arm along the axial direction of the probe 521. The spring 570 can provide a rebound force to the contact element 510 and the probe 521 in a direction away from the sensor 400, and can also improve the overall stability of the trigger rebound assembly 500. It should be noted that, depending on the structure of the measuring arm, the spring 570 can abut against different parts of the measuring arm, and this embodiment does not limit this.

[0063] Optionally, in another embodiment, reference is made to... Figure 7 As shown, the elastic element 522 includes an elastic shell 5223 and a deformable spring sheet 5224 disposed on the outer periphery of the elastic shell 5223. The elastic shell 5223 is disposed at the end of the probe 521 facing the sensor 400. The deformable spring sheet 5224 is curved and along the radial direction of the probe 521. The edge of the deformable spring sheet 5224 away from the elastic shell 5223 is attached to the sensor 400 or the measuring arm. When the contact element 510 is not subjected to external force, there is a gap between the elastic shell 5223 and the sensor 400. When the contact element 510 is subjected to external force, the elastic shell 5223 can press the sensor 400 so that the sensor 400 can collect the pressure change caused by the movement of the jaw and face.

[0064] It should be noted that the curved shape of the deformable spring 5224 can be understood as follows: the cross-sectional shape of the deformable spring 5224 along the radial direction of the probe 521 is arc-shaped, and the distance between the deformable spring 5224 and the sensor 400 gradually decreases in the direction along the radial direction of the probe 521 and away from the probe 521. It should also be noted that the elastic shell 5223 and the curved deformable spring 5224 can be made of silicone material, which ensures the rebound effect while preventing damage to the sensor 400 from the elastic element 522.

[0065] By using the specific structural shape of the elastic element 522, the elastic shell 5223 wraps around the end of the probe 521 facing the sensor 400, so that when the end of the probe 521 facing the sensor 400 touches the sensor 400, it can provide a certain degree of protection for both the sensor 400 and the probe 521.

[0066] In one embodiment, reference Figure 8As shown, the trigger rebound assembly 500 may further include a spring shaft 530 rotatably mounted on the measuring arm. A support arm 531 extends radially from the spring shaft 530, and a contact member 510 is connected to the support arm 531. The spring shaft 530 provides a rebound force to the contact member 510 in a direction away from the sensor 400. When the contact member 510 is not subjected to external force, the pressing member 520 remains in contact with the sensor 400 under the rebound force of the spring shaft 530. When the contact member 510 is subjected to external force, the spring shaft 530 rotates relative to the measuring arm, causing the contact member 510 to move towards the sensor 400, driving the pressing member 520 to press against the sensor 400, thereby enabling the sensor 400 to acquire pressure changes caused by facial movements.

[0067] It should be noted that the pressure member 520 is an elastic structure, or at least part of the pressure member 520 is an elastic structure, so as to achieve the purpose of pressing the sensor 400 while avoiding damage to the sensor 400 when pressing the sensor 400.

[0068] Furthermore, in the direction where the contact 510 points toward the sensor 400, the cross-sectional area of ​​the pressure member 520 gradually decreases. By designing the pressure member 520 into a tapered shape in the direction where the contact 510 points toward the sensor 400, the contact area between the pressure member 520 and the sensor 400 can be further reduced, thereby improving the sensitivity of the monitoring.

[0069] It should also be noted that the aforementioned spring shaft 530 can be understood as a combination structure including a shaft and a limiting spring. The limiting spring allows the shaft to rotate under external force and return to its original position after the external force is removed. The specific structural form of the spring shaft 530 in this embodiment and its function are existing technologies and will not be described in detail here.

[0070] Optionally, in one embodiment, the contact 510 is provided with a first limiting structure, and the measuring arm is provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate to limit the movement distance of the contact 510 along the axial direction of the probe 521. By providing the cooperating first and second limiting structures, the movement range of the contact 510 and the probe 521 can be limited. Thus, under the cooperation of the elastic member 522 or the spring shaft 530, it can be ensured that the contact 520 can press the sensor 400 in the monitoring state, and it can also be ensured that the contact 510 can reset after the monitoring is completed.

[0071] Optionally, in one embodiment, the measuring arm includes a semi-enclosed housing structure for mounting a sensor 400 and a trigger rebound assembly 500. The semi-enclosed housing structure has a cavity for accommodating the sensor 400 and the trigger rebound assembly 500, and an opening. The sensor 400 is mounted on the inner bottom wall of the semi-enclosed housing structure. A contact 510 is resiliently mounted inside the opening of the semi-enclosed housing structure. A pressure member 520 is located within the cavity of the measuring arm. If the pressure member 520 includes a probe 521 and an elastic member 522, the elastic member 522 of the pressure member 520 faces the sensor 400. (Refer to...) Figure 9 As shown, the contact 510 has a first limiting groove 540, and the semi-enclosed housing structure of the measuring arm has a first protrusion 3311. In the direction of the contact 510 pointing to the sensor 400, the first protrusion 3311 is slidably limited in the first limiting groove 540, so as to limit the movement range of the contact 510 and the probe 521 in the direction of the contact 510 pointing to the sensor 400.

[0072] It should be noted that the size of the opening of the first limiting groove 540 can be set to be larger than the size of the first protrusion 3311 in the axial direction of the probe 521, so that the first protrusion 3311 can be slidably limited in the first limiting groove 540 along the axial direction of the probe 521.

[0073] It should also be noted that the first limiting groove 540 on the contact 510 extends in a direction perpendicular to the probe 521, and the first protrusion 3311 extends in a direction perpendicular to the probe 521. This structural arrangement improves the stability of the trigger rebound assembly 500 and prevents the contact 510 from tilting.

[0074] It should also be noted that, in another embodiment, when the trigger rebound assembly 500 includes a spring shaft 530 and a support arm 531, the spring shaft 530 and the support arm 531 are located within the cavity of a semi-enclosed housing structure, as shown in the reference. Figure 8 As shown, it can also be configured such that: the contact member 510 is provided with a second protrusion 560, and the second connecting shell 340 is provided with a second limiting groove 343. In the direction in which the contact member 510 points to the sensor 400, the second protrusion 560 is slidably limited in the second limiting groove 343, so as to limit the movement range of the contact member 510 in the direction in which the contact member 510 points to the sensor 400.

[0075] Optionally, in yet another embodiment, reference is made to... Figure 10As shown, the measuring arm includes a closed housing structure for mounting the sensor 400 and the trigger rebound assembly 500. The closed housing structure has a cavity and a through hole 341 communicating with the cavity and a second limiting hole 342; wherein, the contact member 510 is provided with a limiting rod 550. When the pressure member 520 includes a probe 521 and an elastic member 522, the probe 521 passes through the through hole 341 into the measuring arm, and one end of the probe 521 extends out of the cavity of the measuring arm and connects to the contact member 510. The elastic member 522 at the other end is housed in the cavity of the measuring arm and faces the sensor 400. A spring 570 is sandwiched between the contact member 510 and the measuring arm along the axial direction of the probe 521. A limiting rod 550 passes through the measuring arm through the second limiting hole 342. Along the radial direction of the second limiting hole 342, the size of the end of the limiting rod 550 away from the contact member 510 is larger than the diameter of the second limiting hole 342, so as to slide the end of the limiting rod 550 away from the contact member 510 into the receiving cavity, thereby limiting the movement range of the contact member 510 and the probe 521 along the axial direction of the probe 521.

[0076] In one embodiment, reference Figure 3 As shown, the measuring arm includes a deformable arm 310 and a first connecting shell 320 and a first mounting shell 330 respectively connected to both ends of the deformable arm 310. The first connecting shell 320 is rotatably mounted on the ear hook 120 of the head-mounted mechanism 100, the sensor 400 is disposed within the first mounting shell 330, and the trigger rebound assembly 500 is spring-loaded onto the first mounting shell 330. It should be noted that the first mounting shell 330 can adopt a semi-enclosed shell structure or a closed shell structure as described in the above embodiments. Depending on the structural form of the first mounting shell 330, the contact member 510 and the first mounting shell 330 are provided with matching first and second limiting mechanisms.

[0077] The deformable arm 310 allows for adjustment of the position of the measuring arm relative to the head-mounted mechanism 100, ensuring a proper fit between the contact 510 mounted on the measuring arm and the user's face.

[0078] Optionally, the deformable arm 310 can be made of memory steel wire, elastic steel sheet or elastic plastic sheet.

[0079] Optionally, the deformable arm 310 can be configured with a telescopic structure with respect to the first connecting shell 320 and the first mounting shell 330, which facilitates flexible adjustment of the length of the measuring arm to suit the user.

[0080] In one embodiment, the head-mounted mechanism 100 of this application is provided with a measuring arm, which is equipped with a sensor 400 and a trigger rebound assembly 500. The trigger rebound assembly 500 may adopt the corresponding structural form in any of the above embodiments, and the measuring arm may adopt the second limiting structure that matches the first limiting structure in any of the above embodiments.

[0081] In another embodiment, the measuring mechanism includes multiple measuring arms, each equipped with a sensor 400 and a trigger rebound assembly 500. The multiple measuring arms are respectively connected to different sides of the head-mounted mechanism 100. Optionally, refer to... Figure 11 As shown, the plurality of measuring arms includes a first measuring arm 210 and a second measuring arm 220, which are respectively adjustablely connected to two ear hooks 120 of the head-mounted mechanism 100. It should be noted that both the first measuring arm 210 and the second measuring arm 220 are equipped with a sensor 400 and a trigger rebound assembly 500. The trigger rebound assembly 500 can adopt the corresponding structural form in any of the above embodiments, and the first measuring arm 210 and the second measuring arm 220 can adopt a second limiting structure matching the first limiting structure in any of the above embodiments.

[0082] It should also be noted that the reference Figures 11 to 13 As shown, both the first measuring arm 210 and the second measuring arm 220 are provided with a rotating shaft 610 and a limiting member 620. The rotating shaft 610 and the limiting member 620 on the first measuring arm 210 are matched and connected to the shaft hole 630 and the limiting hole on one ear hook 120 of the head-wearing mechanism 100. The rotating shaft 610 and the limiting member 620 on the second measuring arm 220 are matched and connected to the shaft hole 630 and the limiting hole on the other ear hook 120 of the head-wearing mechanism 100.

[0083] Optionally, the length of the first measuring arm 210 is greater than the length of the second measuring arm 220. By designing the length of the first measuring arm 210 to be greater than the length of the second measuring arm 220, the user can adjust the first measuring arm 210 and the second measuring arm 220 according to their own rehabilitation training when wearing the device, so that the contact pieces 510 on the two measuring arms can accurately fit the area to be monitored, thereby improving the reliability of monitoring.

[0084] It should be noted that the first measuring arm 210 and the second measuring arm 220 in the above embodiments can both be configured to include a deformable arm 310 and a first connecting shell 320 and a first mounting shell 330 respectively connected to both ends of the deformable arm 310; wherein, the first connecting shell 320 is rotatably mounted on the ear hook 120 of the head-mounted mechanism 100, the sensor 400 is disposed inside the first mounting shell 330, and the trigger rebound assembly 500 is spring-loaded onto the first mounting shell 330.

[0085] It should also be noted that in the above embodiments, the first measuring arm 210 and the second measuring arm 220, wherein the first measuring arm 210 may be configured to include a deformable arm 310 and a first connecting shell 320 and a first mounting shell 330 respectively connected to both ends of the deformable arm 310, and the second measuring arm 220 may be configured to include only a semi-enclosed shell structure or a closed shell structure, which is rotatably mounted on the ear hook 120 of the headband mechanism 100.

[0086] To facilitate a further understanding of the apparatus proposed in this application, please refer to... Figures 10 to 14 As shown in the figure, the specific implementation of the device is further illustrated by taking the head-mounted mechanism 100 with the first measuring arm 210 and the second measuring arm 220 installed as an example.

[0087] Example, reference Figure 14 and Figure 15 As shown, the first measuring arm 210 includes a deformable arm 310 and a first connecting shell 320 and a first mounting shell 330 respectively connected to both ends of the deformable arm 310. The first connecting shell 320 is rotatably mounted on an ear hook 120 of the head-mounted mechanism 100. The sensor 400 on the first measuring arm 210 is disposed inside the first mounting shell 330, and the contact member 510 is resiliently disposed on the first mounting shell 330.

[0088] The deformable arm 310 has a first connecting part 311 and a second connecting part 312 at both ends. The first connecting part 311 and the second connecting part 312 can be bent structures. The first connecting part 311 of the deformable arm 310 can be connected to the first connecting shell 320 by fasteners, and the second connecting part 312 of the deformable arm 310 can be connected to the first mounting shell 330 by fasteners.

[0089] The first mounting housing 330 includes an outer shell 331 and an inner shell 332. The outer shell 331 is a semi-closed structure, and the inner shell 332 is installed inside the outer shell 331. The surface of the inner shell 332 has a first positioning groove 3321 for accommodating the sensor 400. The trigger rebound assembly 500 is spring-loaded and installed at the opening of the outer shell 331. The inner shell 332 is connected to the end of the deformable arm 310 away from the first connecting shell 320. Specifically, the inner shell 332 can be connected to the second connecting part 312 of the deformable arm 310 by fasteners.

[0090] On the first measuring arm 210, the pressure member 520 includes a probe 521 and an elastic member 522. The elastic member 522 is sleeved on the probe 521. The elastic member 522 is a silicone head or the elastic member 522 is configured to include an elastic shell 5223 and a deformable spring sheet 5224.

[0091] It should be noted that when the elastic element 522 is designed as a silicone tip, the end cap 5222 of the silicone tip is used to press the sensor 400 inside the first measuring arm 210. It should also be noted that when the elastic element 522 is a silicone tip, a spring 570 can be clamped between the contact 510 and the inner wall of the inner housing 332 along the axial direction of the probe 521. The spring 570 can provide a rebound force to the contact 510 and probe 521 away from the sensor 400, and can also improve the overall stability of the trigger rebound assembly 500.

[0092] It should be noted that when the elastic element 522 is configured to include an elastic shell 5223 and a deformable spring sheet 5224, along the radial direction of the probe 521, the edge of the deformable spring sheet 5224 away from the probe 521 abuts against the sensor 400; when the contact element 510 is not subjected to external force, there is a gap between the elastic shell 5223 and the sensor 400; when the contact element 510 is subjected to external force, the elastic shell 5223 can press against the sensor 400.

[0093] When the user is performing jaw and facial muscle training, as the jaw and facial muscles move, the contact 510 drives the probe 521 to move relative to the measuring arm, so that the elastic element 522 deforms and touches the sensor 400 at the same time, and the sensor 400 collects the pressure change on the contact 510.

[0094] On the first measuring arm 210, a first limiting groove 540 is formed on the contact member 510, and a first protrusion 3311 is provided on the inner wall of the outer shell 331. Along the axial direction of the probe 521, the first protrusion 3311 is slidably limited in the first limiting groove 540 to restrict the movement range of the contact member 510 along the axial direction of the probe 521. The above structure, in conjunction with the elastic member 522, enables the trigger rebound assembly 500 to be springily mounted on the first measuring arm 210, ensuring that pressure changes from the user's face on the contact member 510 can be transmitted to the sensor 400.

[0095] Example, reference Figure 16 and Figure 17 As shown, the second measuring arm 220 includes a second connecting shell 340 and a second mounting shell 350 that form a receiving cavity. The second connecting shell 340 is rotatably mounted on another ear hook 120 of the headband mechanism 100.

[0096] The sensor 400 on the second measuring arm 220 is located inside the second mounting housing 350. The trigger rebound assembly 500 is spring-loaded onto the second connecting housing 340, and the contact member 510 protrudes from the second connecting housing 340 to conform to the face. The pressure member 520 is at least partially housed in the receiving cavity. Under the action of facial movement, the contact member 510 moves relative to the second connecting housing 340 to transmit the force change caused by facial movement to the sensor 400 through the pressure member 520.

[0097] On the second measuring arm 220, the contact 510 is located on the side of the second connecting shell 340 away from the receiving cavity. The pressing member 520 includes a probe 521 and an elastic member 522. The probe 521 passes through the second connecting shell 340, and the elastic member 522 is sleeved on the end of the probe 521 that extends into the receiving cavity. The elastic member 522 is a silicone head, and the end cap 5222 of the silicone head is used to press the sensor 400 inside the second measuring arm 220. Under the elastic force of the silicone head, the contact 510 and the probe 521 rebound adaptively as the pressure applied by the user's face to the contact 510 varies. The limiting rod 550 passes through the second connecting shell 340 and is connected to the contact 510. The end of the limiting rod 550 away from the contact 510 is slidably limited in the receiving cavity. By cooperating with the silicone head and the limiting rod 550, the trigger rebound assembly 500 is springily mounted on the second measuring arm 220, while ensuring that the pressure change from the user's face received by the trigger rebound assembly 500 can be transmitted to the sensor 400.

[0098] It should be noted that when the pressure element 520 on the second measuring arm 220 is designed to include a probe 521 and an elastic element 522, refer to Figure 16 As shown, a through hole 341 and a second limiting hole 342 are provided through the second connecting shell 340. The probe 521 on the second measuring arm 220 passes through the through hole 341 into the second connecting shell 340, and the limiting rod 550 passes through the second limiting hole 342 into the second connecting shell 340. Specifically, along the radial direction of the second limiting hole 342, the dimension of the end of the limiting rod 550 away from the contact member 510 is larger than the diameter of the second limiting hole 342, thereby limiting the position of the limiting rod 550. It should also be noted that when the elastic member 522 is a silicone head, a spring 570 can be sandwiched between the contact member 510 and the outer wall of the second connecting shell 340 along the axial direction of the probe 521. The spring 570 can provide a rebound force to the contact member 510 and the probe 521 in a direction away from the sensor 400, and can also improve the overall stability of the trigger rebound assembly 500.

[0099] Alternatively, in addition to the contact element 510 and the pressing element 520, the trigger rebound assembly 500 on the second measuring arm 220 also includes a spring shaft 530 rotatably mounted on the second connecting housing 340, see reference. Figure 17 As shown, a spring shaft 530 has a support arm 531 extending radially therefrom. A contact 510 is connected to the support arm 531. The spring shaft 530 provides a rebound force to the contact 510 in a direction away from the sensor 400. The second connecting shell 340 has an opening on the side of the shell away from the second mounting shell 350. The contact 510 is mounted at the opening of the second mounting shell 350. The pressing member 520, the spring shaft 530, and the support arm 531 are all located within the receiving cavity. When the contact 510 is not subjected to external force, the pressing member 520 remains in contact with the sensor 400 under the rebound force of the spring shaft 530. When the contact 510 is subjected to external force, the spring shaft 530 rotates relative to the measuring arm, causing the contact 510 to move towards the sensor 400, driving the pressing member 520 to press against the sensor 400, thus allowing the sensor 400 to collect pressure changes caused by facial movements.

[0100] It should be noted that when the trigger rebound assembly 500 includes a contact 510, a pressing member 520 and a spring shaft 530, the pressing member 520 can be configured as an elastic structure, or the pressing member 520 can be configured as at least partially as an elastic structure, so as to achieve the purpose of pressing the sensor 400 while avoiding damage to the sensor 400 when pressing the sensor 400.

[0101] It should also be noted that when the trigger rebound assembly 500 includes a contact member 510, a pressing member 520 and a spring shaft 530, the contact member 510 may be provided with a second protrusion 560 and the second connecting shell 340 is provided with a second limiting groove 343. In the direction in which the contact member 510 points to the sensor 400, the second protrusion 560 is slidably limited in the second limiting groove 343, so as to limit the movement range of the contact member 510 in the direction in which the contact member 510 points to the sensor 400.

[0102] Optionally, a second positioning groove 351 for accommodating the sensor 400 is provided on the inner wall of the second mounting housing 350 on the second measuring arm 220 to prevent the sensor 400 from shifting.

[0103] Optionally, the sensor 400 may be a thin-film pressure sensor, which can accurately detect pressure changes caused by motion deformation.

[0104] It should be noted that multiple sensors 400 can be installed on the measuring arm. The sensors 400 can also be selected from types such as microswitches or gyroscope accelerometer sensors. This embodiment does not limit this.

[0105] It should also be noted that the auxiliary device in this embodiment may be equipped with an audio device, which can be installed on the ear hook 120 of the head-mounted mechanism 100. This audio device can be connected to a smart terminal via Bluetooth for playing rehabilitation training audio. The auxiliary device in this embodiment may also be equipped with a memory and a wireless transceiver, which are electrically connected to the controller. The wireless transceiver is signal-connected to the user terminal and is used to send electrical signal data from the controller to the user terminal. The memory is used to store the electrical signal data.

[0106] It should also be noted that the controller, memory, and wireless transceiver all use conventional models in the existing technology, and their internal structure is a conventional technology structure. Workers can operate them normally by referring to existing technical manuals. In addition, the circuit connection adopts a conventional connection method in the existing technology, so it will not be described in detail here.

[0107] To facilitate understanding of how to use the auxiliary device provided in this embodiment, the following provides an illustrative usage scenario of the auxiliary device.

[0108] The auxiliary device provided in this embodiment is paired and connected to the user terminal via wireless communication equipment. The auxiliary device is then worn on the user's head, and the measuring arm is adjusted so that the contact 510 on the measuring arm accurately fits the area to be tested. After the measuring arm is adjusted, the user begins muscle function training according to the content played by the audio device. During the training, the sensor 400 on the measuring arm collects electrical signal data in real time and sends the collected electrical signal data to the user terminal via the controller. The user terminal analyzes the user's maxillofacial movement state based on the received electrical signal data to obtain the training results. The user terminal can synchronously forward the training results and the muscle training data collected by the sensor 400 to the doctor's management terminal via a cloud server. The user terminal can also send control commands to the controller of the auxiliary device based on the training results to stop the audio device from playing when the training target is met.
