The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of this utility model, wherein terms indicating direction such as up, down, left, and right refer only to the position of the illustrated structure in the corresponding drawings. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following description describes preferred embodiments of the present invention; however, the foregoing description is intended to illustrate the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0029] Please see Figure 1 , Figure 1 This is a structural block diagram of a diagnostic system 1000 provided in an embodiment of the present invention. The diagnostic system 1000 includes a facial and tongue imaging device 100 and a pulse diagnosis device 200. The facial and tongue imaging device 100 and the pulse diagnosis device 200 are independently configured but communicatively connected. Therefore, based on the independent configuration of the facial and tongue imaging device 100 and the pulse diagnosis device 200, and the fact that the facial and tongue imaging device 100 can receive pulse information collected by the pulse diagnosis device 200, the two devices do not interfere with each other, thus improving the comprehensive analytical performance of the diagnostic system 1000 and increasing the accuracy of the diagnostic results.

[0030] The facial and tongue imaging device 100 is equipped with a first communication module 1001. The pulse diagnosis device 200 is equipped with a second communication module 2001. The first communication module 1001 and the second communication module 2001 establish a communication connection. The facial and tongue imaging device 100 also includes a control module 1002. The control module 1002 is electrically connected to the first communication module 1001. The control module 1002 is used to receive and process the facial and tongue image information collected by the facial and tongue imaging device 100 and the pulse information collected by the pulse diagnosis device 200, thereby realizing data transmission between the facial and tongue imaging device 100 and the pulse diagnosis device 200. Furthermore, the pulse information collected by the pulse diagnosis device 200 can be transmitted to the facial and tongue imaging device 100 for centralized monitoring through the second communication module 2001 and the first communication module 1001, thereby realizing the multi-diagnosis function of the diagnostic system 1000, including observation (e.g., tongue and facial image information), auscultation (e.g., sound information such as voice, cough, and wheezing), inquiry (e.g., current symptoms and historical disease information reported by the patient), and palpation (e.g., pulse information). It should be noted that the facial and tongue image information of this utility model may include at least one of tongue image information and facial image information.

[0031] In this embodiment, the first communication module 1001 and the second communication module 2001 establish a wireless communication connection. This achieves two benefits: firstly, it enables a wireless connection between the facial and tongue imaging device 100 and the pulse diagnosis device 200, preventing mutual interference during data collection and enhancing the mobility and flexibility of both devices; secondly, it allows for contactless data transmission between them, improving hygiene and safety. The first communication module 1001 and the second communication module 2001 can be, but are not limited to, Wi-Fi modules, Bluetooth modules, or mobile communication modules such as 2G, 3G, 4G, and 5G. In other embodiments, the pulse diagnosis device 200 can also connect to the facial and tongue imaging device 100 via a cable. For example, in this embodiment, the first communication module 1001 and the second communication module 2001 are both configured as Bluetooth modules, and the facial and tongue imaging device 100 and the pulse diagnosis device 200 establish a communication connection via Bluetooth. Therefore, on the one hand, the low power consumption of the Bluetooth module improves the battery life of the facial and tongue imaging device 100 and the pulse diagnosis device 200; on the other hand, the establishment of a wireless communication connection between the facial and tongue imaging device 100 and the pulse diagnosis device 200 via the Bluetooth module enhances their mobility and flexibility, while also providing reliability and stability for data transmission. Of course, in some embodiments, the first communication module 1001 and the second communication module 2001 can also be configured as other communication modules, and this invention does not impose specific limitations.

[0032] In this embodiment, the facial and tongue imaging device 100 can establish a communication connection with one pulse diagnosis device 200. In some embodiments, the facial and tongue imaging device 100 can establish a communication connection with multiple pulse diagnosis devices 200. Within the same time period, the facial and tongue imaging device 100 only establishes a communication connection with one pulse diagnosis device 200. On the one hand, this prevents data crosstalk and mismatches, improves the accuracy of diagnostic conclusions, and avoids medical accidents; on the other hand, information such as tongue, face, pulse, and symptoms is collected at the same time point or within a very short time interval to reflect the physiological and pathological state of the human body at the same moment. Of course, in other embodiments, within the same time period, the facial and tongue imaging device 100 can establish a communication connection with multiple pulse diagnosis devices 200. The facial and tongue information collected by the facial and tongue imaging device 100 and the pulse information collected by the multiple pulse diagnosis devices 200 are associated and bound with the patient's identity information, thereby improving the diagnostic efficiency of the diagnostic system 1000.

[0033] Please refer to the following: Figures 2 to 3 , Figure 2 yes Figure 1 A schematic diagram of the facial and tongue imaging device 100 in the diagnostic system 1000; Figure 3 yes Figure 2 The diagram shows a partial exploded view of the facial and tongue imaging device 100 from a first-person perspective. The device includes a body 10, an image acquisition unit 50, and a support base 70. The image acquisition unit 50 is mounted on the body 10 and is used to acquire facial and tongue image information of the patient. The body 10 is rotatably mounted on the support base 70, allowing medical personnel and patients to use the device from different positions, thus improving the operational flexibility of the device.

[0034] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement of the body 10, the image acquisition unit 50 and the support base 70, and is not to make specific limitations on the connection positions, connection relationships and specific structures of each component. Figure 1 The diagram only illustrates the structure of the facial and tongue imaging device 100 in this embodiment of the present invention and does not constitute a specific limitation on the facial and tongue imaging device 100. In other embodiments of the present invention, the facial and tongue imaging device 100 may include a... Figure 1 The components shown may include more or fewer components, or combinations of certain components, or different components. For example, the face and tongue imager 100 may also include, but is not limited to, a battery management system, connecting harnesses, etc.

[0035] The image acquisition unit 50 is rotatably connected to the body 10, so that the image acquisition unit 50 can adjust the imaging angle to suit users of different heights. It can correctly project key parts such as the face and tongue onto the camera area, which improves the image quality acquired by the image acquisition unit 50. Furthermore, the acquisition of tongue images and face images share the same image acquisition unit 50, which is simple in structure and saves costs.

[0036] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the face and tongue imaging device 100 also includes a damping hinge 60. The image acquisition device 50 is rotatably connected to the housing 1 in a plane parallel to the height direction Z of the face and tongue imaging device 100 via the damping hinge 60. Thus, on the one hand, the damping hinge 60 provides moderate resistance, preventing the image acquisition device 50 from accidentally shifting due to slight patient movement or operator touch, and the image acquisition device 50 hardly shakes under the damping force after pitch angle adjustment, improving the stability of the image acquisition device 50 at the moment of exposure and reducing the risk of image blurring; on the other hand, the damping hinge 60 eliminates the need for locking screws or additional fixing structures, allowing the user to adjust and fix it instantly with one hand, simplifying the process, improving examination efficiency, extending equipment life, reducing maintenance costs, and preventing the image acquisition device 50 from swaying left and right during pitch adjustment, thereby improving the imaging alignment accuracy of the image acquisition device 50.

[0037] The image acquisition device 50 includes a camera housing 51 and a camera 52. The camera 52 is mounted on the camera housing 51. A damping hinge 60 connects the camera housing 51 and the body 10. The body 10 also includes a housing 1 and a support frame 2 disposed within the housing 1. One end of the support frame 2 is fixedly connected to the housing 1, and the other end of the support frame 2 is fixedly connected to the damping hinge 60. A receiving cavity 101 is provided inside the housing 1. The image acquisition device 50 is detachably connected to the top of the housing 1 and located outside the receiving cavity 101, thereby facilitating the disassembly, maintenance, and replacement of the image acquisition device 50 and improving the operational flexibility of the image acquisition device 50. Of course, in some embodiments, the image acquisition device 50 can also be non-detachably connected to the housing 1, and this embodiment of the present invention does not specifically limit this. In other embodiments, the support frame 2 can be omitted from the body 10, that is, the damping hinge 60 is directly fixedly connected to the housing 1.

[0038] The body 10 also includes a support frame 3 disposed within the housing 1. The support frame 3 is fixedly connected to the housing 1 and is configured as a sheet metal frame. A support frame 2 is located above the support frame 3. One end of the support frame 2 is fixedly connected to the damping hinge 60 and is bent relative to the damping hinge 60. The other end of the support frame 2 is fixedly connected to the support frame 3. Thus, on the one hand, by configuring the support frame 2 as a sheet metal frame, and by having the housing 1 cover and fix it to the outside of the support frame 3, and by mounting the support frame 2 on a metal sheet metal frame, the support frame 3 can provide rigid support for the stress points of the various functional components of the face imager 100, avoiding the problem of creep deformation of the plastic housing due to frequent adjustment of the pitch angle of the image acquisition unit 50, thereby improving the overall structural strength of the body 10. Furthermore, the housing 1 can absorb the mechanical vibration generated by the rotation of the image acquisition unit 50 relative to the housing 1 and the body. The mechanical vibration generated during operation of the camera body 10 is reduced, and the stability of the center of gravity of the camera body 10 is improved. On the other hand, the support frame 2 is bent and connected to the damping hinge 60 so that the support frame 2 extends toward the side of the support frame 3 and is fixed to the housing 1 by the support frame 3. The damping hinge 60 extends toward the side closer to the camera housing 51, so that the support frame 2 and the damping hinge 60 are connected to form a three-dimensional support frame, thereby optimizing the torque distribution and reducing the torque generated by the pitch operation, and extending the service life of the face and tongue imager 100.

[0039] The housing 1 also has a through hole 103 communicating with the accommodating cavity 101. The end of the damping hinge 60 facing away from the image acquisition unit 50 passes through the through hole 103 and is fixedly connected to the support frame 2. Thus, on the one hand, the structure of the support frame 2 is hidden inside the accommodating cavity 101, thereby reducing the external volume of the face imager 100 and enabling the replacement and maintenance of the damping hinge 60 without disassembling the housing 1, thus reducing maintenance costs; on the other hand, the accommodating cavity 101 provides a closed rigid support for the support frame 2, reducing the interference of external vibrations on the image acquisition unit 50 and improving the imaging alignment accuracy of the image acquisition unit 50.

[0040] A limiting protrusion 111 is provided on the outer wall of the housing 1 facing the image acquisition unit 50. A through hole 103 passes through the two end faces of the limiting protrusion 111. The limiting protrusion 111 is used to limit the pitch angle range of the image acquisition unit 50 relative to the housing 1. Thus, on the one hand, the limiting protrusion 111 can limit the rotation angle of the image acquisition unit 50, avoiding problems such as cable pulling or mechanical interference caused by over-adjustment; on the other hand, when the image acquisition unit 50 rotates to the limit angle, the impact force is transmitted to the entire housing 1 through the limiting protrusion 111, rather than being borne only by the hinge shaft, reducing local wear.

[0041] Exemplarily, in this embodiment, the housing 1 includes a front housing 110 and a rear housing 120. The front housing 110 and the rear housing 120 are fixedly connected and enclose a receiving cavity 101. The front housing 110 and the rear housing 120 are detachably fitted and fixed, thereby facilitating the assembly, maintenance, and replacement of internal components of the housing 10. For example, the front housing 110 and the rear housing 120 can be detachably fixed together by means of a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc. Of course, in some embodiments, the housing 1 includes an upper housing and a lower housing. The upper housing and the lower housing are detachably connected and form the receiving cavity 101. It should be noted that the configuration of the housing 1 can be set according to the actual situation, and this embodiment of the utility model does not impose a specific limitation.

[0042] In some embodiments, the rear housing 120 includes a first housing 121, a second housing 122, and a third housing 123. The third housing 123 is connected between the first housing 121 and the second housing 122, and the first housing 121 and the second housing 122 are located between the front housing 110 and the third housing 123. The first housing 121, the second housing 122, and the third housing 123 are detachably connected to each other, thereby reducing the processing difficulty of the housing 1.

[0043] In this embodiment, the housing 1 also includes a bottom housing 130. The bottom housing 130 is fixedly connected to the front housing 110 and the rear housing 120, forming an accommodating cavity 101. The bottom housing 130 is detachably fitted and fixed to the front housing 110 and the rear housing 120, thereby facilitating the assembly, maintenance, and replacement of internal components of the housing 10. For example, the bottom housing 130 can be detachably fixed to the front housing 110 and the rear housing 120 through a snap-fit ​​structure, screw locking, magnetic adsorption structure, etc. Of course, in some embodiments, the bottom housing 130 can be omitted, that is, the housing 1 only includes the front housing 110 and the rear housing 120. It should be noted that the structure and connection method of the housing 1 can be set according to the actual situation, and this embodiment of the utility model does not make specific limitations.

[0044] The image acquisition unit 50 is installed on the top of the front shell 110 of the device, which makes it easier for the image acquisition unit 50 to acquire the image of the tongue from the top that meets the standards of traditional Chinese medicine tongue diagnosis, avoid distortion and obstruction, and conform to ergonomic design, so that the operation of the patient to extend the tongue and the medical staff to hold and aim are more natural, efficient and accurate.

[0045] The main body 10 also includes a display 5 mounted on the housing 1. The housing 1 also has a display window 102 communicating with the receiving cavity 101. The display 5 is mounted at the display window 102, and the display 5 and the image acquisition device 50 are mounted on the front housing 110 of the main body, so that the display 5 can provide visual information to the user and remind the user to maintain the correct posture when the image acquisition device 50 is performing its acquisition work. The display 5 is electrically connected to the control module 1002. The control module 1002 is electrically connected to the display 5 and the image acquisition device 50, and is used to receive and process the facial and tongue image information acquired by the image acquisition device 50 and the pulse information acquired by the pulse diagnosis device 200, and to control the display 5 to display the facial and tongue image information and pulse information processed by the control module 1002. Therefore, on the one hand, the body 10 is integrated into the facial and tongue imaging device 100, which facilitates the use of the facial and tongue imaging device 100 in community hospitals, home visits, or remote consultation scenarios. Moreover, the facial and tongue imaging device 100 can quickly enter the diagnostic process upon power-on without the need for an external computer, improving the diagnostic efficiency of the facial and tongue imaging device 100. Furthermore, the integrated structure formed by connecting the body 10 and the image acquisition device 50 can reduce the risk of connection failure. On the other hand, based on the independent settings of the facial and tongue imaging device 100 and the pulse diagnosis device 200, and the fact that the body 10 of the facial and tongue imaging device 100 can receive the pulse information collected by the pulse diagnosis device 200, the facial and tongue imaging device 100 and the pulse diagnosis device 200 do not interfere with each other, improving the accuracy of the diagnostic results and enhancing the comprehensive analysis performance of the diagnostic system 1000.

[0046] The display surface of the monitor 5 is set at an angle to the center of gravity of the body 10. In the projection plane perpendicular to the height direction Z of the facial and tongue imaging device 100, the center of the monitor 5 lies within the orthographic projection of the support base 70 onto the height direction Z of the facial and tongue imaging device 100. Therefore, on the one hand, when the center of the monitor 5 is within the projection range of the support base 70, the overturning moment generated by the weight of the monitor 5 is directly offset by the supporting force of the base, improving the anti-tipping ability of the facial and tongue imaging device 100 and reducing the overall center of gravity height of the body 10; on the other hand, it facilitates viewing the visual content displayed on the monitor 5 by users or medical personnel, enhancing the user experience of the facial and tongue imaging device 100.

[0047] For example, in this embodiment, the body 10 also includes an energy storage component 6. The energy storage component 6 is installed at the bottom of the housing 1. Specifically, the energy storage component 6 is installed on the support frame 3 and located at the bottom of the housing 1. Thus, on the one hand, the energy storage component 6 is installed on the housing 1 via the support frame 3, thereby securing the battery and preventing the energy storage component 6 from becoming loose, having poor contact, or even short-circuiting due to movement or falling of the facial and tongue imaging device 100; on the other hand, the energy storage component 6 is installed at the bottom of the housing 1, thereby lowering the center of gravity of the body 10 and preventing the image acquisition device 50 from tipping over when adjusting the pitch angle; furthermore, the built-in energy storage component 6 eliminates the constraints of the power cord, making it convenient for medical staff or patients to operate, improving the convenience of the facial and tongue imaging device 100, and enabling flexible use in environments such as clinics, wards, or outdoors.

[0048] In some embodiments, the energy storage component 6 is disposed at the bottom of the housing 1. Therefore, by placing the energy storage component 6 at the bottom of the housing 1, the overall center of gravity of the housing 10 is lowered, improving the anti-tipping ability of the housing 10. It is understood that since the weight of the energy storage component 6 is relatively large compared to the weight of other functional components of the housing 10, this embodiment of the invention places the center of the energy storage component 6 close to the center of gravity of the housing 10, so that the mass distribution of the face and tongue imager 100 is shifted downwards, thereby lowering the center of gravity position of the face and tongue imager 100, reducing the risk of the face and tongue imager 100 tipping over, and improving the stability of the face and tongue imager 100 detection. In other words, the orthographic projection of the center of gravity of the housing 100 in the height direction Z of the face and tongue imager 100 is located inside the orthographic projection of the energy storage component 6 in the height direction Z of the face and tongue imager 100.

[0049] The energy storage component 6 can be configured as a rechargeable energy storage structure or a disposable energy storage structure. A rechargeable energy storage structure may include, but is not limited to, a rechargeable capacitor or a rechargeable battery. Exemplarily, in this embodiment, the energy storage component 6 is configured as a rechargeable energy storage structure. The shape of the energy storage component 6 can be generally rectangular or cylindrical. The regular shape of the energy storage component 6 allows it to fit more closely to the bottom contour of the body 10, optimizing space utilization and center of gravity concentration, and avoiding uneven weight distribution caused by irregularly shaped energy storage components 6.

[0050] For example, in this embodiment, the support frame 3 is configured as a sheet metal frame, and the energy storage component 6 is mounted on the housing 1 through the support frame 3. Therefore, on the one hand, by configuring the housing 1 as a plastic structure, the support frame 3 as a sheet metal frame, and mounting the energy storage component 6 on the metal support frame 3, the face-tongue imager 100 is made lightweight. The housing 1 can also improve the structural design flexibility through injection molding, reducing the weight of the upper housing 1 while increasing structural strength. The housing 1 can also absorb the mechanical vibration generated by the body 10 during operation. On the other hand, the support frame 3 can improve the deformation resistance of the housing 1, and the rigid constraint of the support frame 3 can prevent the energy storage component 6 from shifting, maintain the initial center of gravity of the body 10, and reduce the risk of creep caused by the temperature generated by the energy storage component 6 during operation, preventing the energy storage component 6 from loosening. Furthermore, the support frame 3, as a metal sheet metal part, can serve as an auxiliary heat dissipation channel, conducting the heat generated by the energy storage component 6 during operation to the outside of the outer shell or heat sink. The metal sheet metal part can be pre-installed with the energy storage component 6 before being assembled with the housing 1, realizing modular assembly and simplifying the production line process.

[0051] In some embodiments, the face and tongue imaging device 100 further includes a microphone 8. The microphone 8 is disposed on the top of the housing 1 and located below the image acquisition device 50. A microphone hole 104 is also provided on the housing 1 corresponding to the position of the microphone 8. When the image acquisition device 50 is rotated relative to the housing 1 to its maximum tilt angle, the camera housing 51 and the microphone hole 104 are positioned out of alignment, and the projection of the image acquisition device 50 in the projection plane perpendicular to the height direction Z of the face and tongue imaging device 100 covers the projection of the microphone hole 104 in the projection plane perpendicular to the height direction Z of the face and tongue imaging device 100. In other words, when the image acquisition device 50 is rotated relative to the housing 1 to a third position, the camera housing 51 and the microphone hole 104 are positioned out of alignment. Therefore, on the one hand, when the image acquisition device 50 is rotated to its maximum tilt angle, the camera housing 51 and the microphone hole 104 are arranged to avoid each other, thus maintaining the unobstructed sound acquisition channel and avoiding problems such as sound distortion or blockage of the microphone hole 104 due to structural collision. Moreover, the tilt adjustment range is not limited by the position of the microphone 8, so that the image acquisition device 50 can cover a larger angle. On the other hand, by placing the image acquisition device 50 and the microphone 8 on the top of the housing 1, which is close to the patient's mouth and face, the quality of image and sound acquisition is improved. Furthermore, the microphone hole 104 is naturally blocked by the camera housing 51, which improves the aesthetics of the facial and tongue imaging device 100. The camera housing 51 can also prevent contaminants such as oral droplets and tongue coating from splashing into the microphone hole 104, reducing the risk of microbial accumulation. In addition, the gap between the camera housing 51 and the housing 1 forms a Helmholtz resonant cavity, which reduces the interference of environmental noise and improves the sound acquisition effect of the microphone 8.

[0052] It should be noted that the height direction Z refers to the direction perpendicular to the support platform, which is used to place the face and tongue imager 100. The front side of the housing 1 refers to the side of the face and tongue imager 100 facing the subject when taking a picture of the subject's face and tongue, and the rear side of the housing 1 refers to the side of the face and tongue imager 100 facing away from the subject when taking a picture of the subject's face and tongue.

[0053] In some embodiments, the housing 10 further includes a speaker 4. The speaker 4 is disposed at the bottom of the housing 1. The housing 1 is provided with a plurality of sound outlets 105 communicating with the accommodating cavity 101 corresponding to the speaker 4. The display 5 is located between the speaker 4 and the microphone 8. The orthographic projection of the image acquisition device 50 on the housing 1 blocks the orthographic projection of the microphone 8 on the housing 1, and the image acquisition device 50 and the microphone 8 are arranged to avoid each other. Therefore, on the one hand, the long-distance separation between the speaker 4 and the microphone 8 can effectively reduce feedback and prevent the sound output by the speaker 4 from being picked up by the microphone 8 a second time; on the other hand, the display 5 is located between the speaker 4 and the microphone 8, and the display 5 can act as a physical isolation barrier to reduce electromagnetic interference between electronic components; the microphone 8 is set at the top of the front shell 110, which makes the microphone 8 closer to the user's mouth, making it easier to clearly pick up the user's voice commands, while the speaker 4 is set at the bottom of the front shell 110, which keeps the speaker 4 away from the user's mouth and nose area, reducing the risk of saliva or droplet contamination and conforming to human usage habits; furthermore, the heat generated by the speaker 4 when it is working is quickly dissipated through the bottom of the shell 1, avoiding the problem of temperature rise affecting the microphone 8 set at the top of the front shell 110 or the display 5 set in the middle of the front shell 110. The structural layout is reasonable and compact.

[0054] The speaker 4 can be mounted on at least one of the housing 1 and the support frame 3. The speaker 4 and the energy storage unit 6 are laid flat on the bottom of the housing 1. Thus, on the one hand, when the speaker 4 is mounted on the plastic housing 1, the housing 1 can absorb the high-frequency resonance in the speaker 4, avoiding "metallic sound coloration" caused by metal, and avoiding the risk of short circuit caused by the magnetic circuit of the speaker 4 coming into contact with the metal support frame 3. When the speaker 4 is mounted on the support frame 3, local overload of the housing 1 is avoided. On the other hand, the energy storage unit 6 and the speaker 4 are laid flat on the bottom of the housing 1, thereby lowering the overall center of gravity of the body 10 and improving the anti-tipping ability of the body 10.

[0055] In this embodiment, the casing 10, for example, further includes a control circuit board 9. The control circuit board 9 includes a first circuit board 91 and a second circuit board 92. The support frame 3 is provided with a support groove 301. The energy storage device 6, the first circuit board 91, and the second circuit board 92 are installed within the support groove 301. The extending direction of the first circuit board 91 intersects the extending direction of the second circuit board 92. The first circuit board 91 is located above the energy storage device 6 and is electrically connected to the energy storage device 6. The second circuit board 92 is disposed opposite to the display 5 and is electrically connected to both the display 5 and the first circuit board 91. Therefore, on the one hand, by installing the energy storage device 6, the first circuit board 91, and the second circuit board 92 within the support groove 301, the utilization rate of the three-dimensional space inside the housing 1 is improved, as well as the structural strength of the support frame 3 is enhanced. On the other hand, by placing the first circuit board 91 above the energy storage device 6 and electrically connecting it to the energy storage device 6, and by setting the second circuit board 92 opposite to the display 5 and electrically connecting it to the display 5 and the first circuit board 91, the connection lines between the first circuit board 91 and the second circuit board 92 are shortened, and the energy storage device 6 can supply power to functional devices such as the display 5, the first circuit board 91, and the second circuit board 92. Furthermore, since the extension directions of the first circuit board 91 and the second circuit board 92 intersect, it is convenient to set up functional components on the first circuit board 91 and the second circuit board 92, reducing mutual inductance coupling and crosstalk, and facilitating the individual replacement or upgrade of the first circuit board 91 and the second circuit board 92. Of course, in some embodiments, the housing 10 may include only one of the first circuit board 91 and the second circuit board 92; this utility model embodiment does not impose specific limitations.

[0056] Both the control module 1002 and the first communication module 1001 can be mounted on either the first circuit board 91 or the second circuit board 92. Exemplarily, in this embodiment, both the control module 1002 and the first communication module 1001 are mounted on the first circuit board 91. Therefore, since the control module 1002 and the first communication module 1001 are the electronic components with the highest power consumption in the entire housing 10, mounting them both on the first circuit board 91 close to the energy storage device 6 shortens the power supply trace distance, reduces line impedance, avoids voltage drops, and ensures stable operation of the housing 10 under high current demands.

[0057] The support frame 3 includes a base plate 31, a top plate 32, a back plate 33, and two side plates 34. The base plate 31, top plate 32, back plate 33, and two side plates 34 are fixedly connected and enclose a support groove 301. In this embodiment, the base plate 31, top plate 32, back plate 33, and two side plates 34 are integrally formed, thereby improving the reliability and stability of the connection between the base plate 31, top plate 32, back plate 33, and two side plates 34, and improving the assembly efficiency of the face and tongue imager 100. Of course, in some embodiments, at least two of the base plate 31, top plate 32, back plate 33, and two side plates 34 are detachably connected together by an installation structure. The connection method of the base plate 31, top plate 32, back plate 33, and two side plates 34 is not specifically limited in this embodiment of the present invention.

[0058] The bottom plate 31 is fixedly connected to the energy storage component 6 on the side facing the top plate 32. The top plate 32 is fixedly connected to the support frame 2 on the side facing away from the bottom plate 31. The back plate 33 is fixedly connected to the rear side of the bottom plate 31 and to the second circuit board 92. The two side walls are arranged opposite each other and fixedly connected to the bottom plate 31 and the back plate 33. The second circuit board 92 is fixedly connected between the two side plates 34. Specifically, each side plate 34 is provided with at least one bearing plate 341, and the second circuit board 92 is mounted on the bearing plate 341. Thus, based on the reasonable layout of the various functional components of the facial tongue imager 100 on the support frame 3, the compactness and rationality of the overall structure of the facial tongue imager 100 are improved.

[0059] The support plate 341 and the side plate 34 are integrally formed, thereby improving the connection reliability and stability between the support plate 341 and the side plate 34, as well as improving the assembly efficiency of the support plate 341 and the side plate 34. Specifically, the side plate 34 is provided with a cut edge, and the portion of the side plate 34 corresponding to the cut edge is flipped towards the support groove 301 to form the support plate 341. In some embodiments, the support plate 341 and the side plate 34 are independently arranged and fixedly connected.

[0060] Each side plate 34 can be trapezoidal or triangular in shape. For example, in this embodiment, the side plate 34 is approximately triangular in shape. The width of each side plate 34 gradually decreases from bottom to top in the arrangement direction from the image acquisition unit 50 to the body 10, thereby enhancing the overall structural strength of the support frame 3 and improving the anti-tipping ability of the image acquisition unit 50 when adjusting the pitch angle.

[0061] The base body 72 is configured as a metal base. The orthographic projection of the center of gravity of the fuselage 10 in the height direction Z of the face and tongue imager 100 lies within the orthographic projection of the supporting base 70 in the height direction Z of the face and tongue imager 100. Therefore, on the one hand, by configuring the base body 72 as a metal base, the mass distribution of the face and tongue imager 100 is shifted downwards, thereby lowering the center of gravity of the face and tongue imager 100, reducing the risk of tipping over, and improving the stability of the face and tongue imager 100 detection; on the other hand, because the orthographic projection of the center of gravity of the fuselage 10 in the height direction Z of the face and tongue imager 100 lies within the orthographic projection of the supporting base 70 in the height direction Z of the face and tongue imager 100, the torque generated by the gravity of the fuselage 10 is absorbed by the supporting base. The reaction force of the supporting surface of the seat 70 is offset, thereby preventing the face and tongue imager 100 from tipping over. On the one hand, the image acquisition unit 50 is rotatably connected to the top of the housing 1, thereby increasing the acquisition angle range of the image acquisition unit 50 and adapting to the shooting needs of different users. On the other hand, by setting the energy storage unit 6 and the speaker 4 at the bottom of the housing 1 and setting the image acquisition unit 50 at the top of the housing 1, the layout rationality of the face and tongue imager 100 is improved, and the anti-tipping ability of the image acquisition unit 50 is improved when adjusting the pitch angle.

[0062] The cross-sectional area of ​​the body 10 in the height direction Z perpendicular to the face imager 100 gradually decreases from the support base 70 to the body 10. Therefore, the body 10 is designed to be narrower at the top and wider at the bottom, so that the bottom of the body 10 has a larger volume, which can concentrate more weight at the bottom and lower the overall center of gravity.

[0063] For example, in this embodiment, the body 10 is generally teardrop-shaped. Therefore, the near-circular bottom of the teardrop-shaped housing 1 provides a uniform distribution of support force. When the image acquisition device 50 performs pitch movements, the friction between the bottom of the base body 72 and the support surface is more balanced, reducing the risk of tilting. Of course, in some embodiments, the body 10 can also be cone-shaped, but is not limited to, frustum-shaped, etc.

[0064] Please refer to the following: Figures 4 to 8 , Figure 4 yes Figure 2 An exploded schematic diagram of the partial structure of the face and tongue imaging device 100 from the second perspective; Figure 5 yes Figure 2 An exploded view of the first-angle support base 70 of the face and tongue imager 100. Figure 6 yes Figure 2 An exploded view of the second perspective of the support base 70 of the face and tongue imager 100. Figure 7 yes Figure 2 Cross-sectional view of the face tongue imager 100 Figure 8 yes Figure 7This is an enlarged view of part I of the facial imaging device 100. The support base 70 includes a connecting frame 71 and a base body 72. The connecting frame 71 includes a connecting shaft 711 and a connecting plate 712. One end of the connecting shaft 711 is fixedly connected to the body 10. The other end of the connecting shaft 711 is fixedly connected to the connecting plate 712. The support base 70 includes a seat body 721, a first bearing member 73, and a second bearing member 74. The seat body 721 is provided with a first annular groove 7201, a second annular groove 7202, and a shaft hole 7203. The first annular groove 7201 and the second annular groove 7202 are respectively located at both ends of the seat body 721 in the height direction Z of the support base 70, and are connected through the shaft hole 7203. The first bearing member 73 is installed in the first annular groove 7201 and is located between the body 10 and the seat body 721. The second bearing component 74 is installed in the second annular groove 7202 and is located between the seat 721 and the connecting plate 712. The connecting shaft 711 is rotatably inserted into the shaft hole 7203.

[0065] The support base 70 provided in this embodiment of the utility model has two advantages. First, the connecting shaft 711 is rotatably installed in the shaft hole 7203 of the base body 721, and the body 10 of the facial and tongue imaging device 100 is fixedly connected to the connecting shaft 711. This allows the body 10 to rotate relative to the base body 72 at different angles with the connecting shaft 711, so that medical staff and patients can use the facial and tongue imaging device 100 in different positions, improving the operational flexibility of the facial and tongue imaging device 100 and reducing the cleaning difficulty of the facial and tongue imaging device 100. Second, the first bearing member 73 and the second bearing member 74 are respectively provided at both ends of the base body 721 to form symmetrical axial support, thereby dispersing the radial and axial loads when the body 10 rotates relative to the support base 70, reducing single-point stress concentration, and suppressing vibration or sway when the body 10 rotates, thus improving the stability of the body 10 rotation.

[0066] In this embodiment, the connecting shaft 711 and the connecting plate 712 are independently arranged and fixedly connected, thereby facilitating the assembly, maintenance, and replacement of the connecting shaft 711 and the connecting plate 712. Of course, in some embodiments, the connecting shaft 711 and the connecting plate 712 can also be integrally formed; this embodiment of the present invention does not impose specific limitations. The base body 72 is disposed between the connecting plate 712 and the machine body 10, thereby restricting the movement of the base body 72 relative to the machine body 10 in the height direction Z of the face and tongue imaging device 100, and restricting the movement of the base body 72 relative to the machine body 10 in a plane perpendicular to the height direction Z of the face and tongue imaging device 100.

[0067] The bottom of the fuselage 10 is provided with a connecting hole 1301 communicating with the accommodating cavity 101. The support frame 3 is exposed at the connecting hole 1301, thereby facilitating the assembly of the connecting shaft 711 and the support frame 3. The connecting shaft 711 passes through the connecting hole 1301 and is fixedly connected to the support frame 3. Therefore, by fixing the connecting shaft 711 to the support frame 3, the reliability and stability of the fixed connection between the connecting frame 71 and the support frame 3 are improved, avoiding the problem of reduced reliability of the connection between the connecting frame 71 and the fuselage 10 due to creep of the fuselage 10 when the connecting frame 71 is directly fixedly connected to it. This further improves the reliability and safety of the rotation of the fuselage 10 relative to the support base 70. Exemplarily, in this embodiment, the bottom of the fuselage bottom shell 130 is provided with a connecting hole 1301 communicating with the accommodating cavity 101. In some embodiments, a flange 7111 extends radially from the end of the connecting shaft 711 facing away from the connecting plate 712. The flange 7111 is fixedly connected to the support frame 3.

[0068] In this embodiment, a grip portion 115 is provided on the body 10. Therefore, the grip portion 115 provides a gripping position for the user, facilitating the user's operation of the body 10 to rotate relative to the support base 70. The grip portion 115 is configured as a protruding structure provided on the edge of the front housing 110 of the body. Specifically, two protruding structures are provided on the two sides of the front housing 110 to form two grip portions 115.

[0069] In some embodiments, the base body 72 further includes a bushing 75. The bushing 75 is installed within the shaft hole 7203. The connecting shaft 711 is rotatably inserted through the bushing 75. Thus, on the one hand, the bushing 75 avoids the problem of wear or scratches caused by direct contact between the connecting shaft 711 and the base body 72, extending the service life of the support base 70; on the other hand, the bushing 75 can also correct the machining error of the shaft hole 7203, improve the coaxiality of the bushing 75 and the connecting shaft 711, reduce radial runout or wobble when the connecting shaft 711 drives the machine body 10 to rotate, provide uniform radial support, and avoid vibration or noise caused by uneven clearance when the connecting shaft 711 rotates.

[0070] In this embodiment, for example, the bushing 75 and the base body 72 are independently disposed. The bushing 75 is rotatably disposed within the shaft hole 7203. In some embodiments, the bushing 75 is fixedly connected to the base body 72. The bushing 75 is fixedly disposed within the shaft hole 7203. The bushing 75 can be fixedly connected by screw connection, interference fit, locking structure, or other means.

[0071] For example, in this embodiment, a support boss 722 is provided on the base 721 near the center of the body 10. The support boss 722 has a stepped portion 7221 around the periphery of the shaft hole 7203. The bushing 75 includes a sleeve portion 751 and an overlapping portion 752, the overlapping portion 752 is connected to one end of the sleeve portion 751 in the axial direction and overlaps the stepped portion 7221. Therefore, on the one hand, the support boss 722 forms a thickened area in the middle of the base body 72, enhancing the bending and torsional stiffness of the base body 72 around the shaft hole 7203, avoiding stress concentration at the edge of the shaft hole 7203, and reducing the risk of deformation or cracking of the base body 72; on the other hand, the step portion 7221 provides a precise axial positioning reference for the bushing 75, preventing the bushing 75 from moving along the direction of the shaft hole 7203 during installation or operation, improving the coaxiality of the bushing 75 and the connecting shaft 711, and reducing radial runout or sway when the connecting shaft 711 drives the body 10 to rotate. Exemplarily, in this embodiment, the support boss 722 protrudes from the bottom wall of the first annular groove 7201.

[0072] The base body 72 has an extended protrusion 723 on the outer edge of the first annular groove 7201, and the body 10 has a mating groove 1302 that mates with the extended protrusion 723. Thus, on the one hand, the mating of the extended protrusion 723 and the mating groove 1302 forms a labyrinth-like sealing structure, preventing external dust and liquid from entering the first bearing area and extending bearing life; on the other hand, the mating of the extended protrusion 723 and the mating groove 1302 forms a physical alignment structure, guiding the body 10 and the support base 70 to quickly align during assembly, improving assembly efficiency and yield.

[0073] In some embodiments, the end face of the connecting plate 712 near the connecting shaft 711 is provided with a plurality of slots 7120 spaced apart along the circumferential direction of the connecting shaft 711. The base body 72 also includes an elastic snap-fit ​​member 78 disposed on the base body 721. The elastic snap-fit ​​member 78 engages with any one of the slots 7120 and can be detachably accommodated within the corresponding slot 7120. Thus, on the one hand, the plurality of slots 7120 are spaced apart along the circumferential direction of the connecting shaft 711, thereby allowing the relative angle or position between the connecting plate 712 and the base body 72 to be adjusted in stages to adapt to different angle requirements of the face and tongue imaging device 100; on the other hand, the elastic snap-fit ​​member 78 can be quickly snapped into any one of the slots 7120, and fixation can be completed without tools, improving the adjustment efficiency of the rotation of the body 10 and enabling the body 10 to be fixed relative to the base body 72 after rotating to a designated position, thereby improving the stability and reliability of the face and tongue imaging device 100 in operation.

[0074] The end face of the base 721 near the connecting plate 712 is provided with a receiving groove 7205. The elastic snap-fit ​​component 78 includes an elastic element 781 and a ball 782, with the elastic element 781 housed in the receiving groove 7205. The ball 782 snaps into the elastic element 781 and engages with the snap-fit ​​groove 7120. Therefore, on the one hand, the ball bearing 782, pushed by the elastic element 781, is engaged in different slots 7120, realizing multi-position angle or position adjustment of the connecting plate 712 and the base body 72. Furthermore, the ball bearing 782 can be disengaged from the slot 7120 with a slight rotation or translation of the connecting plate 712, allowing for quick adjustment without tools and improving the operating efficiency of the machine body 10 rotation. On the other hand, the elastic element 781 always applies radial pressure to the ball bearing 782, ensuring that the ball bearing 782 and the slot 7120 fit tightly, eliminating assembly gaps and preventing the connecting plate 712 and the machine body 10 from shaking. Moreover, the ball bearing 782 produces a distinct "click" sound and feel when it is engaged in the slot 7120, indicating to the user that the adjustment is in place, avoiding misoperation, and improving the human-machine interaction effect.

[0075] Exemplarily, in this embodiment, a limiting boss 724 is provided in the middle of the base body 721 facing away from the fuselage 10. Exemplarily, in this embodiment, the limiting boss 724 protrudes from the bottom wall of the second annular groove 7202. In other words, the second annular groove 7202 is arranged around the outside of the limiting boss 724. Thus, on the one hand, the limiting boss 724 forms a thickened area in the middle of the base body 72, enhancing the bending and torsional stiffness of the base body 72 around the shaft hole 7203, avoiding stress concentration at the edge of the shaft hole 7203, and reducing the risk of deformation or cracking of the base body 72. The bottom surface of the base body 721 facing away from the fuselage 10 is higher than the end face of the limiting boss 724 facing away from the base body 721, thereby realizing that the connecting plate 712 is housed in the recess 7204, which is simple and compact. The housing groove 7205 is provided on the limiting boss 724, thereby reducing the risk of deformation or cracking of the base body 72.

[0076] The support base 70 also includes at least one first washer 76 and / or at least one second washer 77. The first washer 76 is disposed between the first bearing member 73 and the body 10 and / or between the first bearing member 73 and the seat 721; the second washer 77 is disposed between the second bearing member 74 and the seat 721 and / or between the second bearing member 74 and the connecting plate 712. Thus, on the one hand, the thickness of the first washer 76 and the second washer 77 can finely adjust the axial installation clearance of the first bearing member 73 or the second bearing member 74, improving the pre-tightening state of the first bearing member 73 or the second bearing member 74 and reducing radial runout or sway when the connecting shaft 711 drives the body 10 to rotate; on the other hand, the first washer 76 and the second washer 77 make the axial force distribution of the first bearing member 73 or the second bearing member 74 more uniform, preventing local stress concentration from damaging the first bearing member 73 or the second bearing member 74, and reducing the wear of the first bearing member 73 or the second bearing member 74.

[0077] The first washer 76 and the second washer 77 can be configured as elastic structures. For example, the first washer 76 and the second washer 77 can be configured as, but are not limited to, plastic structures, nylon structures, resin structures, etc. Exemplarily, in this embodiment, the first washer 76 and the second washer 77 are configured as plastic structures. Therefore, the first washer 76 and the second washer 77 can absorb the axial installation clearance of the first bearing member 73 or the second bearing member 74 during minor deformation, improving the pre-tightening state of the first bearing member 73 or the second bearing member 74 and reducing radial runout or sway when the connecting shaft 711 drives the machine body 10 to rotate. Of course, the first washer 76 and the second washer 77 can also be configured as rigid structures. Rigid structures can be configured as, but are not limited to, stainless steel structures or high-carbon chromium bearing steel structures, etc., and this embodiment of the present invention does not impose specific limitations.

[0078] In some embodiments, the bottom of the base 721 is further provided with a recess 7204 communicating with the second annular groove 7202. The connecting plate 712 is housed within the recess 7204. The recess 7204 covers the second annular groove 7202, and the edge of the recess 7204 is located outside the outer edge of the second annular groove 7202. The second bearing member 74 abuts against the connecting plate 712. Thus, on the one hand, the connecting plate 712 is completely housed within the recess 7204, reducing external protrusions, making the bottom of the base flatter, saving installation space, and improving the aesthetics of the support base 70; on the other hand, the recess 7204 covers the second annular groove 7202, forming a physical barrier to prevent dust, liquids, etc., from directly intruding into the second bearing member 74, extending the service life of the second bearing member 74; furthermore, when the second bearing member 74 needs maintenance, the second bearing member 74 can be directly exposed simply by removing the connecting plate 712, without disassembling the entire base body 72, reducing maintenance costs.

[0079] In this embodiment, the first bearing member 73 and the second bearing member 74 are configured as thrust bearings. This configuration increases the bidirectional axial force transmitted to the fuselage 10, extends the service life of the first bearing member 73 and the second bearing member 74, and provides strict axial constraint to prevent axial movement of the fuselage 10 or the connecting plate 712 during operation, thus improving transmission accuracy. Of course, in some embodiments, the first bearing member 73 and the second bearing member 74 can also be configured as tapered roller bearings or angular contact ball bearings.

[0080] In some embodiments, the support base 70 further includes an anti-slip pad 79. The anti-slip pad 79 is disposed at the bottom of the base body 721 and located in the area of ​​the base body 721 outside the second annular groove 7202. Thus, on the one hand, the anti-slip pad 79 increases the coefficient of friction, preventing the fuselage 10 from rotating relative to the support base 70 or the base body 72 from displacing relative to the support platform due to external forces; on the other hand, it reduces or isolates the contact area between the base body 72 and the support platform, reduces scratches caused by friction, and improves the reliability and stability of the fuselage 10 rotating relative to the support base 70.

[0081] The anti-slip pad 79 can be configured as, but is not limited to, a suction cup structure, a magnetic structure, or a plastic structure. For example, in this embodiment, the anti-slip pad 79 is configured as a plastic structure, thereby increasing the friction between the support base 70 and the support platform, preventing the face and tongue imager 100 from sliding and tipping over.

[0082] In this embodiment, the number of anti-slip pads 79 is set to multiple. These multiple anti-slip pads 79 are spaced apart along the circumferential direction of the shaft hole 7203, thereby improving the uniformity of force distribution on the bottom of the support base 70 and reducing the risk of slippage and overturning of the face-tongue imager 100. The anti-slip pads 79 are generally arc-shaped.

[0083] In some embodiments, the number of anti-slip pads 79 can also be configured to be one. The anti-slip element can be annular in shape, thereby improving the uniformity of force distribution on the bottom of the support base 70 and reducing the risk of the face tongue imager 100 sliding and overturning.

[0084] In some embodiments, an anti-slip groove 7206 is provided at the bottom of the base body 72. An anti-slip pad 79 is housed within the anti-slip groove 7206. Specifically, the anti-slip groove 7206 is formed by an indentation in the bottom wall of the seat body 721 facing away from the main body 10. The depth of the anti-slip groove 7206 is equal to the thickness of the anti-slip pad 79 in the height direction Z of the face and tongue imager 100, thereby preventing dust or other debris from the external environment from remaining in the gap between the support base 70 and the support platform, and increasing the contact area between the support base 70 and the support platform, reducing the risk of the face and tongue imager 100 sliding and tipping over. Of course, in some embodiments, the depth of the anti-slip groove 7206 can also be greater than the thickness of the anti-slip pad 79 in the height direction Z of the face and tongue imager 100; this embodiment of the present invention does not impose a specific limitation.

[0085] In some embodiments, the anti-slip pad 79 is disposed at the bottom edge of the base body 72 to prevent dust or other debris from the external environment from remaining in the gap between the support base 70 and the support platform.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
