Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and in particular to a pair of multifunctional glasses. Background Art

[0002] Multifunctional glasses for oral cavity are wearable devices that integrate multiple advanced technologies and functions. They are designed to improve the efficiency and accuracy of dental clinical operations or laboratory production of oral restorations, while ensuring the comfort and safety of medical staff.

[0003] In order to meet the diverse visual needs in dental clinical operations or laboratory production of oral restorations, the multifunctional glasses currently on the market usually require medical personnel to manually replace lenses with specific functions, such as switching the glasses function mode in the dental laboratory to observe the details of the teeth, or switching from the observation mode to a higher magnification mode in dental clinical operations. This process not only requires medical personnel to have certain operating skills, but also may interrupt the workflow due to frequent replacement of lenses or adjustment of mechanical structures, resulting in a waste of time and reduced efficiency. In addition, manual adjustment may also damage the precision parts of the glasses due to improper operation, increasing maintenance costs. In order to adapt to more medical personnel, multifunctional glasses integrate multiple functions including myopia, presbyopia correction, magnification, focal length adjustment, etc., which often leads to a heavy frame and lens. Wearing such glasses for a long time, medical personnel may feel that the bridge of the nose and ears are under great pressure, and even pain or discomfort. In addition, the increase in the weight of the lens part may also increase the risk of glasses falling off, especially when performing delicate oral restoration work, the falling off of glasses will seriously affect the continuity and safety of work. In addition, the design of some multifunctional glasses may limit the field of vision of medical personnel, which not only affects the freedom of daily activities of medical personnel, but also poses a potential threat to their safety. In dental clinical operations or when technicians are making oral restorations, the limited field of vision may prevent doctors from fully observing the patient's oral condition and technicians from fully observing the surface condition of the restoration, thereby increasing the risk of misjudgment and operational errors. In addition, in a work environment that requires frequent movement and turning, limited field of vision may also increase the possibility of safety accidents such as collisions and falls.

[0004] In view of the above problems, it is necessary to propose a multifunctional pair of glasses that can enhance the design of intelligence, lightness and wide field of view in dental clinical operations or in the production of oral restorations in the laboratory, so as to meet the needs of medical staff for work efficiency, wearing comfort and safety. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a kind of multifunctional glasses, which realizes light and intelligent wearing effect by designing functional components that can be unfolded when needed, and taking into account the adjustment functions of focal length and magnification, and supplemented by wearing reinforcement with synchronous adjustment function.

[0006] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: a multifunctional pair of glasses, comprising two frames, a nose bridge for connecting the two frames is arranged between the two frames, temples are hingedly connected on the sides of the two frames away from each other, corrective lenses are detachably connected in the frames, ear hook air bags are fixedly connected to the bottoms of the ends of the two temples away from the frames, and nose pad air bags located below the nose bridge are fixedly connected to the sides of the two frames close to each other;

[0007] The side of the temple close to the frame is hinged with a hollow connecting tube, and a driving component for driving the connecting tube to swing is arranged in the connecting tube. The side of the connecting tube away from the frame is rotatably connected to a bearing block, and a transmission component for transmitting and converting the rotational force of the driving component into a force for driving the bearing block to rotate and swing is arranged at the connection between the connecting tube and the bearing block;

[0008] A displacement groove is provided in each bearing block, and an electric telescopic rod is fixedly connected to a side wall of one side of the displacement groove, and a piston is fixedly connected to an output end of the electric telescopic rod, and the piston is slidably matched with the inner wall of the corresponding displacement groove, and a connecting rod is fixedly connected to the side of the piston away from the connecting cylinder, and the end of the connecting rod away from the piston penetrates the side wall of the displacement groove and extends to the outside of the bearing block, and a sliding groove corresponding to the moving track of the connecting rod is provided on the bearing block, and a magnifying lens is fixedly connected to the end of the connecting rod away from the piston;

[0009] A control component for starting and adjusting the drive is arranged on the temple, and the electric telescopic rod and the drive component are both connected with the control component signal.

[0010] The technical principle of the above scheme is as follows: it is composed of two frames connected by a nose bridge, and each frame is hinged with a temple to adapt to the head shape of different medical personnel to ensure wearing comfort. In order to improve the stability and comfort of wearing, an ear hook airbag is fixed at the bottom of the temple, and the nose pad airbag is designed to reduce the pressure on the bridge of the nose. In addition, a driving component is installed inside the connecting tube, and the rotational force is transmitted to the bearing block at the far end of the connecting tube through the transmission component, so that it can be automatically swung out, reducing the space occupied by the functional components on the glasses. Mainly, a displacement groove driven by an electric telescopic rod is provided in the bearing block. When the electric telescopic rod is working, the piston drives the connecting rod and the magnifying lens to move, so as to realize the extension and retraction of the magnifying lens; medical personnel can easily start and mediate the work of the driving component and the electric telescopic rod through the control component on the temple, so as to conveniently control the various functions of the glasses, which not only meets the needs of vision correction, but also greatly improves the convenience and comfort of use.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This solution integrates a storable magnifying function on the glasses. Through the mechanical transmission cooperation of the driving component and the transmission component, the connecting tube and the bearing block carrying the magnifying lens are rotated and swung out to reach the front of the corrective lens, and then the electric telescopic rod is used to drive the magnifying lens to extend and retract. Medical personnel can easily switch between observation mode and normal wearing mode as needed. While integrating multiple functions, it does not affect the normal use of the corrective lens. The bearing block carrying the magnifying lens is stored on both sides of the temples to reduce the obstruction of the field of vision during normal wear.

[0013] 2. This solution designs a signal connection between the control component and the electric telescopic rod to achieve distance adjustment between the magnifying lens and the corrective lens. Through intelligent control of the distance adjustment, the magnification and focal length adjustment can be precisely controlled, allowing medical personnel to independently adjust the magnification, making the focal length adjustment more precise, more in line with the medical personnel's needs, and improving the convenience and accuracy of use.

[0014] Furthermore, the hinge between the temple and the frame includes a fixed platform fixedly connected to the temple, one end of the connecting tube is located in the fixed platform, a servo motor is fixedly connected to the bottom wall of the fixed platform, a through hole corresponding to the servo motor is opened on the connecting tube, and a rotating shaft for driving the connecting tube to swing and realize separate rotation is provided on the output shaft of the servo motor, and the servo motor is connected to the control component signal.

[0015] Beneficial effects: The signal connection between the servo motor and the control component enables medical personnel to accurately control the start, stop, rotation direction and angle of the servo motor through the control component, which is crucial for realizing the swing function of the bearing block, ensuring the swing out of the bearing block, that is, the realization of the magnification function, accurately extending when needed, and timely retracting when not needed. In addition, it can also ensure that the bearing block always presents the effect of being parallel and closely fitting to the frame, ensuring the realization of the magnification function, and improving the stability and comfort of wearing.

[0016] Furthermore, the rotating shaft includes a connecting shaft, a sleeve shaft and a fixed shaft. The connecting shaft passes through the connecting cylinder and is fixedly connected to the top wall of the connecting cylinder. The bottom end of the fixed shaft is coaxially fixedly connected to the output shaft of the servo motor. The sleeve shaft is sleeved on the outer wall of the fixed shaft and slidably cooperates with the outer wall of the fixed shaft. A spring is fixedly connected to the bottom end of the sleeve shaft. The end of the spring away from the sleeve shaft is fixedly connected to the fixed shaft. The top end of the sleeve shaft is fitted with the bottom end of the connecting shaft. The fitting place of the sleeve shaft and the connecting shaft is a toothed structure. A first bevel gear is fixedly sleeved on the surface of the sleeve shaft. A threaded groove is opened on the inner wall of the sleeve shaft. A threaded engraving is provided on the outer wall of the fixed shaft. The height of the threaded engraving and the threaded groove corresponds to the tooth height at the fitting place of the sleeve shaft and the connecting shaft.

[0017] Beneficial effects: This solution not only realizes the efficient and stable transmission of the servo motor's rotation by cleverly dividing the rotating shaft into a combination of a connecting shaft, a sleeve shaft and a fixed shaft, but also can easily achieve the engagement and disengagement of the connecting shaft and the sleeve shaft when the connecting cylinder is subject to rotation limit. By utilizing the sliding fit mechanism of the sleeve shaft and the fixed shaft, and the thread engraving and the thread groove to achieve the role of the "slider slide groove", this design ensures that the sleeve shaft can accurately adjust the degree of freedom after rotating a specific angle, realizes the smooth disengagement of the toothed structure when the limit is reached, and ensures the rotation stability of the sleeve shaft relative to the connecting shaft after disengagement. At the same time, the spring, as an elastic element, not only provides sliding power, but also plays a key buffering role, reducing the impact and vibration caused by engagement and disengagement, which not only improves the reliability and stability of the system, but also maintains a high transmission accuracy even in long-term use or harsh environments, and can also provide a guarantee for the return of the sleeve shaft in the subsequent process of reversing the servo motor to retract the connecting cylinder.

[0018] Furthermore, the transmission assembly includes a second bevel gear that can be vertically meshed with the first bevel gear, the meshing height difference between the second bevel gear and the first bevel gear is the same as the tooth height at the joint between the sleeve shaft and the connecting shaft, the second bevel gear is fixedly connected to a through rod rotatably connected to the connecting cylinder on the side away from the first bevel gear, the through rod is fixedly connected to a third bevel gear on the end away from the second bevel gear, the third bevel gear is meshed with a fourth bevel gear rotatably connected to the bottom wall of the connecting cylinder, a driven rod is fixedly connected to the bottom of the fourth bevel gear, and the driven rod is fixedly connected to the bearing block on the side away from the fourth bevel gear.

[0019] Beneficial effect: After the sleeve shaft slides relatively on the fixed shaft, the height of the first bevel gear decreases, and the decreased height is the tooth height at the joint of the sleeve shaft and the connecting shaft, which just makes the first bevel gear mesh with the second bevel gear. Then the servo motor continuously drives the rotational power through the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear to mesh in sequence, and transmit in sequence, realizing efficient transmission from the servo motor to the bearing block, reducing energy loss in the transmission process, and improving the accuracy and stability of the transmission. In addition, the design realizes the versatility of the servo motor drive, so that one drive source can achieve two drive results, reducing the need for additional drive devices, thereby reducing the complexity and manufacturing cost of the overall system.

[0020] Furthermore, the corrective lens is a progressive multifocal corrective lens.

[0021] Beneficial effects: Progressive multifocal correction lenses are suitable for a variety of vision needs, including myopia, hyperopia, and presbyopia. They can meet the wearer's visual needs in different life and work scenarios, such as reading, computer work, outdoor activities, etc., and improve the practicality and applicability of glasses. Progressive multifocal correction lenses integrate the visual focus of different distances, such as far, medium, and near, on a single correction lens through a smooth transition area, reducing the wearer's eye adjustment burden when switching to view objects at different distances, and providing a more natural and comfortable visual experience.

[0022] Furthermore, a negative pressure airbag is fixedly connected to the side of the piston away from the electric telescopic rod, and the ear hook airbag and the nose pad airbag are both connected to the negative pressure airbag.

[0023] Beneficial effects: Since the magnifying lens has weight, according to the principle of lever, the greater the distance between the magnifying lens and the electric telescopic rod, the greater the upward pull on the frame and the greater the risk of falling off. The design of the negative pressure airbag enables the pressure state inside the negative pressure airbag to change when the electric telescopic rod pushes the piston to move, thereby affecting the inflation and deflation of the ear-hook airbag and the nose pad airbag through the connecting pipe, so that the inflation and deflation can be synchronized with the displacement of the magnifying lens. When the magnifying lens is away from the corrective lens, the negative pressure airbag is squeezed, and the ear-hook airbag and the nose pad airbag are inflated to better fit the face and head of the medical staff, ensuring that the glasses fit closely to the facial contour of the medical staff, improving the fixing effect of the device to the face of the medical staff, and reducing the risk of falling off. On the contrary, when the magnifying lens approaches the corrective lens, the negative pressure airbag expands due to the pulling force of the piston pushed in the opposite direction by the electric telescopic rod, causing the internal pressure of the negative pressure airbag to decrease, causing the ear hook airbag and the nose pad airbag to gradually deflate, thereby reducing the pressure on the face and head. When the glasses adjust the position of the magnifying lens, they can automatically adjust the inflation and deflation status of the ear hook airbag and the nose pad airbag, ensuring that the glasses can maintain a tight fit while providing appropriate wearing pressure according to the actual needs of medical staff.

[0024] Furthermore, the control component includes a start button, a stop button and a control system for receiving and processing signals sent by each button when pressed. The start button and the stop button are both connected to the control system signal, and the start button and the stop button are respectively fixedly connected to the outer walls of the temples on both sides.

[0025] Beneficial effects: The start button and stop button are fixed on the outer wall of the temples on both sides, so that medical staff can easily reach and operate them, which improves the convenience of use. At the same time, the physical button provides intuitive tactile feedback. Medical staff can directly control the functions of the glasses, such as start and stop, by pressing the button, which enhances the operation experience of medical staff. In addition, the control system can quickly respond to button signals to achieve instant control of the functions of the glasses, improving the reaction speed and efficiency. Moreover, the simple button design makes it easy for even medical staff who are not familiar with technology to use it, lowering the threshold for use.

[0026] Furthermore, a rotation angle sensor is fixedly connected to the driven rod, and the rotation angle sensor is connected to the control system signal.

[0027] Beneficial effects: The introduction of the angle sensor enables the control system to obtain the actual angle information of the driven rod in real time. Through precise measurement and feedback, the control system can achieve precise control of the angle of the driven rod to ensure that it reaches the predetermined position and angle during movement. In addition, since the angle sensor can provide angle data in real time, the control system can respond quickly and adjust the output of the drive motor, thereby speeding up the response speed of the system.

[0028] Further, the control system includes a signal receiving module, a signal processing module, a turning angle acquisition module, a judgment module, a driving module and a pause module;

[0029] A signal receiving module, used to receive the signal sent by the medical staff pressing the button;

[0030] A signal processing module is used to analyze and identify the signal as a signal transmitted by the start button or a signal transmitted by the stop button, and convert the signal representing "start" into a control signal for driving the servo motor to rotate forward or convert the signal representing "stop" into a control signal for driving the servo motor to rotate reversely, and then transmit the control signal to the drive module;

[0031] A rotation angle acquisition module, used to detect and collect the rotation angle information of the driven rod through a rotation angle sensor;

[0032] A judgment module, used to judge whether the rotation angle information meets the requirements;

[0033] A driving module, used to control the start and stop of the servo motor and the electric telescopic rod according to the control signal;

[0034] The pause module is used to recognize the signal that the medical staff presses the stop button twice to temporarily stop the driving of the electric telescopic rod.

[0035] Beneficial effects: The design of the glasses control system integrates multiple modules such as signal reception, signal processing, angle acquisition, judgment, drive and pause, realizing the friendliness, precise control, real-time feedback, safety protection, intelligent control and high scalability of medical personnel's interaction. By accurately receiving and converting the button signals of medical personnel, accurately controlling the movement of the servo motor and the electric telescopic rod, real-time detection and feedback of the rotation angle information of the driven rod, and providing an emergency stop function, the system not only ensures the accuracy and stability of the glasses when adjusting the position of the magnifying lens, but also greatly improves the use experience and safety of medical personnel. At the same time, its intelligent control and scalability design enable the system to adapt to the future development of technology and the changing needs of medical personnel, and provide support for more application scenarios and medical personnel's needs.

[0036] Furthermore, in the judgment module, when the rotation angle of the driven rod collected by the rotation angle sensor is 90°, which meets the position requirement for the magnifying lens to work, the judgment module sends a control signal for the periodic extension and shortening of the electric telescopic rod to the driving module.

[0037] Beneficial effects: The judgment module accurately judges the rotation angle of the driven rod collected by the angle sensor. When the angle reaches 90°, it is considered that the magnifying lens has reached the working position requirement, ensuring that the magnifying lens can accurately reach the predetermined position each time it is adjusted, thereby improving the accuracy and reliability of the adjustment. In addition, after the magnifying lens working position requirements are met, the judgment module sends a control signal for the periodic extension and shortening of the electric telescopic rod to the driving module, so that medical personnel can change the focal length of the magnifying lens by adjusting the extension and shortening of the electric telescopic rod according to actual needs, thereby achieving fine-tuning of the magnification and clarity of the observed object.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The following is further described in detail through specific implementation methods:

[0053] Embodiment 1:

[0054] As attached Figure 1 As shown, a multifunctional pair of glasses comprises two frames 1, wherein the two frames 1 are hinged with temples 2 on the sides away from each other, a nose bridge 3 is arranged between the two frames 1, and the two ends of the nose bridge 3 are respectively fused to the two frames 1, and corrective lenses 4 are detachably connected to the frames 1 through card slots, the bottoms of the rear ends of the two temples 2 are fixedly connected to ear hook air bags 5 through straps, and the side walls of the two frames 1 on the sides close to each other are fixedly connected to nose pad air bags 6 located below the nose bridge 3.

[0055] Due to the symmetrical design of the multifunctional glasses, the left side frame 1 and the temple 2 are taken as an example for explanation. Figure 1 and Figure 2As shown, a fixing platform 7 is welded to the left side of the temple 2, and a connecting tube 8 is rotatably connected to the inner bottom wall of the fixing platform 7 through a bearing, a bearing block 9 is provided on the side of the connecting tube 8 away from the frame 1, and a through hole 10 is provided at the connection between the connecting tube 8 and the fixing platform 7. A servo motor 11 located in the through hole 10 is fixedly connected to the bottom wall of the fixing platform 7 through a screw, and the output shaft of the servo motor 11 is coaxially fixedly connected to a rotating shaft 12 through a coupling, and the rotating shaft 12 passes through the top wall of the connecting tube 8 and extends to the top wall of the fixing platform 7 and is rotatably connected to the top wall of the fixing platform 7 through a bearing, and the rotating shaft 12 is fixedly connected to the connecting tube 8 at the through point, and when the servo motor 11 is started, the power is directly transmitted to the rotating shaft 12 through the coupling, and the rotating shaft 12 rotates smoothly under the support of the bearing. Since the rotating shaft 12 is fixedly connected to the connecting tube 8 at the through point, this design ensures that the connecting tube 8 can rotate with the rotating shaft 12, and realizes the effect that the forward and reverse rotation of the servo motor 11 drives the connecting tube 8 to swing out for use clockwise and retract counterclockwise.

[0056] In detail, in order to enable the rotation of the servo motor 11 to be transmitted to the rotating shaft 12 so as to be separated from the state of being fixedly connected with the connecting tube 8, the rotating shaft 12 is designed as shown in the attached figure. Figure 3 As shown, the rotating shaft 12 includes a connecting shaft 1201, a sleeve shaft 1202 and a fixed shaft 1203. The connecting shaft 1201 is a part that penetrates the connecting cylinder 8 and is fixedly connected to the top wall of the connecting cylinder 8. The fixed shaft 1203 is a part that is fixed to the output shaft of the servo motor 11. The sleeve shaft 1202 is located between the fixed shaft 1203 and the connecting shaft 1201 and is sleeved on the outer wall of the fixed shaft 1203. The sleeve shaft 1202 is slidably matched with the outer wall of the fixed shaft 1203, and a spring 1204 is fused to the bottom end of the sleeve shaft 1202. The end of the spring 1204 away from the sleeve shaft 1202 is connected to the fixed shaft. The outer wall of the bottom of 1203 is welded, the top of the sleeve shaft 1202 is fitted with the bottom of the connecting shaft 1201, and the fitting place of the sleeve shaft 1202 and the connecting shaft 1201 is a toothed structure. When the servo motor 11 drives the connecting cylinder 8 to rotate 180°, the connecting cylinder 8 will contact the inner wall of the fixed platform 7 to limit the position. The function of the limit position causes the toothed fitting place of the sleeve shaft 1202 and the connecting shaft 1201 to be relatively displaced, that is, the sleeve shaft 1202 and the connecting shaft 1201 are staggered, and the sleeve shaft 1202 can slide a distance relative to the fixed shaft 1203 along its outer wall. The movement after the stagger is shown in the figure. Figure 4 shown.

[0057] At this time, specifically Figure 5As shown, since the surface of the fixed shaft 1203 is provided with a threaded carving 1207, and the inner wall of the sleeve shaft 1202 is provided with a threaded groove 1206 corresponding to the threaded carving 1207, when the sleeve shaft 1202 slides along the surface of the fixed shaft 1203 to the height of the threaded carving 1207, the threaded carving 1207 slides along the threaded groove 1206, thereby improving the subsequent rotation stability of the sleeve shaft 1202, and the toothed portion at the top of the sleeve shaft 1202 and the corresponding toothed portion at the bottom of the connecting shaft 1201 are no longer tightly meshed, thereby allowing the rotating shaft 12 to have a certain degree of freedom relative to the connecting cylinder 8. At this time, the spring 1204, as an elastic element, plays a key role in buffering and resetting. Before the connecting tube 8 rotates into position and triggers the limit, the spring 1204 is in a normally released state. Once the limit is reached, the spring 1204 begins to compress and store part of the elastic potential energy. The rotation of the servo motor 11 drives the sleeve shaft 1202 to slide downward relative to the fixed shaft 1203, so that the sleeve shaft 1202 engages and disengages with the tooth structure on the connecting shaft 1201. When the servo motor 11 reverses, the sleeve shaft 1202 is subject to the upward force of the energy released by the spring 1204. The threaded engraving 1207 in the sleeve shaft 1202 will slide down along the threaded groove 1206, so that the sleeve shaft 1202 is re-engaged with the connecting shaft 1201, thereby achieving the effect of reverse swinging to retract the connecting tube 8 and the supporting block 9.

[0058] At this time, the fixed shaft 1203 and the sleeve shaft 1202 rotating in the connecting tube 8 become a new driving source to achieve different functions, as shown in the attached figure. Figure 3 and Figure 6As shown, a first bevel gear 1205 is sleeved and fixed on the sleeve shaft 1202, and a second bevel gear 13 is rotatably connected to a rotating ring suspended by a rod in the connecting tube 8. The second bevel gear 13 can mesh with the first bevel gear 1205, and when the second bevel gear 13 is not meshed with the first bevel gear 1205, the height difference between the second bevel gear 13 and the first bevel gear is the same as the tooth height at the joint of the sleeve shaft 1202 and the connecting shaft 1201. When the sleeve shaft 1202 and the connecting shaft 1201 are fitted and disengaged, the sleeve shaft 1202 will slide downward relative to the surface of the fixed shaft 1203 by an end distance. At this time, the sliding distance is just enough to make the first bevel gear 1205 fall and mesh with the second bevel gear 13, so that the second bevel gear 13 has a transmission function. When the sleeve shaft 1202 rotates along the track of the thread engraving, the first bevel gear 1205 can be meshed with the second bevel gear 13. At this time, since the second bevel gear 13 is welded with a through rod 14 on the side away from the first bevel gear 1205, and the through rod 14 is welded with a third bevel gear 15 on the end away from the second bevel gear 13, the third bevel gear 15 is meshed with a fourth bevel gear 16 rotatably connected to the bottom wall of the connecting cylinder 8 through a bearing, and a driven rod 17 is welded at the bottom of the fourth bevel gear 16, and the driven rod 17 is welded to the bearing block 9 on the side away from the fourth bevel gear 16. When the second bevel gear 13 is meshed and rotated, when the second bevel gear 13 is meshed and rotated with the first bevel gear 1205, its rotational power is transmitted to the third bevel gear 15 through the welded through rod 14. Since the third bevel gear 15 is meshed with the fourth bevel gear 16 rotatably connected to the bottom wall of the connecting cylinder 8 through a bearing, the change of the rotation direction and the continuous transmission of power are ensured. As the third bevel gear 15 rotates, the fourth bevel gear 16 also starts to rotate, and the welded follower rod 17 at the bottom thereof rotates accordingly. The other end of the follower rod 17 is welded to the bearing block 9, so when the follower rod 17 rotates, the bearing block 9 also rotates or performs a specific swinging motion, realizing that the rotational motion of the sleeve shaft 1202 and the fixed shaft 1203 is finally converted into the swinging motion of the bearing block 9 through the meshing conversion of a series of bevel gears.

[0059] Since the driven rod 17 is fixedly connected with the angle sensor 18 by screws, and the temple 2 is provided with a control component for starting and adjusting the drive, and the drive component includes a start button 19, a stop button 20 and a control system, the angle sensor 18 and the servo motor 11 are both connected to the control system signal, the angle sensor 18 will detect and collect the rotation angle of the driven rod 17 in real time, that is, the rotation angle of the supporting block 9, and transmit the angle information to the control system, and control the rotation angle by controlling the start and stop of the servo motor 11.

[0060] When the bearing block 9 rotates to a position parallel to the corrective lens 4, the magnification function of the present invention can be realized. Figure 7As shown, a displacement groove 21 is opened in the bearing block 9, and the right side wall of the displacement groove 21 is fixedly connected with an electric telescopic rod 22 by screws. The electric telescopic rod 22 is connected with the control system signal, and the output end of the electric telescopic rod 22 is fixedly connected with a piston 23 through a coupling. The piston 23 slides in contact with the inner wall of the displacement groove 21. When the electric telescopic rod 22 receives a start signal, it starts to work, and its output end pushes the piston 23 to slide smoothly and stably along the inner wall of the displacement groove 21.

[0061] The piston 23 is fixedly connected to a connecting rod 24 integrally formed with the piston 23 at the front side away from the connecting tube 8. Figure 8 As shown, the end of the connecting rod 24 away from the piston 23 passes through the side wall of the displacement groove 21 and extends to the outside of the bearing block 9. A slide groove 25 corresponding to the moving trajectory of the connecting rod 24 is provided on the bearing block 9. As the electric telescopic rod 22 continues to advance, the piston 23 drives the connecting rod 24 integrally formed therewith to move synchronously. The design of the slide groove 25 plays a key guiding role. It not only limits the moving trajectory of the connecting rod 24, but also ensures that the magnifying lens 26 can move smoothly on the predetermined path to avoid shaking or deviation, which is crucial to achieve precise focusing.

[0062] The end of the connecting rod 24 away from the piston 23 is fixedly connected with a magnifying lens 26 through a pin. As the connecting rod 24 gradually extends out of the outer side of the bearing block 9 along the slide groove 25 under the drive of the electric telescopic rod 22, the magnifying lens 26 also moves accordingly. As the magnifying lens 26 gradually moves away from the initial position of the bearing block 9, the distance from the magnifying lens 26 to the observation target (such as an object or image) changes. According to the optical principle, this will cause the object in the observation field to be magnified to varying degrees. Through the precise control of the electric telescopic rod 22, the position of the magnifying lens 26 can be fine-tuned, thereby realizing the fine adjustment of the magnification of the observation target. Finally, when the magnifying lens 26 reaches the optimal position, that is, the medical staff can clearly and magnify the target object through the corrective lens 4 and the magnifying lens 26, the electric telescopic rod 22 stops working and maintains the current state. At this time, the magnification function of the present invention is realized, and the medical staff can press the stop button 20 to transmit a signal to the control system as needed, thereby adjusting the working state of the electric telescopic rod 22 and switching the observation mode at any time, which is both convenient and practical.

[0063] Embodiment 2:

[0064] As attached Figure 1 and Figure 7As shown, the difference from Example 1 is that the piston 23 is fixedly connected to a negative pressure airbag 27 on the side away from the electric telescopic rod 22, and the ear hook airbag 5 and the nose pad airbag 6 are both connected to the negative pressure airbag 27. When the piston 23 moves forward, it squeezes the negative pressure airbag 27, so that the gas in the airbag is compressed and the pressure increases. However, since the outlet of the negative pressure airbag 27 is connected to the ear hook airbag 5 and the nose pad airbag 6, when the pressure inside the airbag exceeds a certain threshold, the gas will quickly flow to the ear hook airbag 5 and the nose pad airbag 6 through the connecting pipe. The ear hook airbag 5 and the nose pad airbag 6 are respectively located behind the wearer's ears and below the bridge of the nose 3, and can closely fit the shape of the human facial contour to ensure wearing comfort and stability. When the gas in the negative pressure airbag 27 flows into these airbags, they will expand and fit more closely to the wearer's face and head, thereby increasing the fixing force of wearing, ensuring that even when the magnifying lens 26 is moved to a farther position to meet the magnification factor or focus clarity, thereby increasing the distance from the medical staff's face, the ear hook airbag 5 and the nose pad airbag 6 can respond quickly, and automatically adjust their expansion degree through the gas pressure transmitted by the negative pressure airbag 27, so as to fit tightly to the face and head of the medical staff, effectively preventing the lenses from accidentally falling off, which not only enhances the safety of wearing, but also avoids loose wearing or discomfort caused by the movement of the magnifying lens 26.

[0065] Embodiment 3:

[0066] The difference from Example 2 is that the corrective lens 4 is a progressive multifocal corrective lens 4. The progressive multifocal corrective lens 4 is a specially designed lens that can integrate multiple focal length areas on a single corrective lens 4, thereby meeting the wearer's visual needs at different distances. The present invention can not only effectively realize the magnification function during normal use, but also take into account the correction of presbyopia and myopia problems at the same time, providing visual convenience for medical personnel who wear it.

[0067] Embodiment 4:

[0068] As attached Fig. 9 As shown, the difference from Example 3 is that the control system includes a signal receiving module, a signal processing module, a turning angle acquisition module, a judgment module, a driving module and a pause module.

[0069] During dental clinical operations or in the process of making oral restorations in the laboratory, when the medical staff cannot clearly observe the affected tooth or the restoration because it is too small, first, the medical staff presses the start button 19, and the signal receiving module receives the signal sent by the medical staff pressing the start button 19. The signal receiving module performs preliminary processing on the received original signal and converts it into a digital signal so that subsequent modules can perform further analysis and identification, thereby ensuring the rapid transmission of the medical staff's intentions and laying a solid foundation for the response speed of the entire control system.

[0070] The signal processing module analyzes and identifies the signal as the signal transmitted by the start button 19 or the signal transmitted by the stop button 20, and correspondingly converts the signal representing "start" into a control signal for driving the servo motor 11 to rotate forward or converts the signal representing "stop" into a control signal for driving the servo motor 11 to rotate reversely, and then transmits the control signal to the drive module.

[0071] The angle acquisition module detects and collects the rotation angle information of the driven rod 17 through the angle sensor 18. The angle acquisition module converts the collected angle information into a digital signal and feeds it back to the judgment module in real time for subsequent judgment and decision-making, ensuring that the magnifying lens 26 can accurately reach the predetermined working position and achieve an accurate magnification effect.

[0072] The judgment module judges whether the rotation angle information meets the requirements. When the rotation angle of the driven rod 17 collected by the rotation angle sensor 18 is 90°, the position requirement of the magnifying lens 26 is met. The judgment module sends a control signal for the periodic extension and shortening of the electric telescopic rod 22 to the driving module.

[0073] The driving module controls the start and stop of the servo motor 11 and the electric telescopic rod 22 according to the control signal, which can ensure that the motor and the telescopic rod can respond quickly and accurately after receiving the control signal.

[0074] The pause module recognizes the signal that the medical staff presses the stop button 20 twice, and determines the pressing timing of the stop button 20 according to the observed magnification and clarity to temporarily stop the driving of the electric telescopic rod 22.

[0075] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
