Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a head-mounted fully automated optometer for ophthalmology. Background Technology

[0002] As a professional instrument for objectively and precisely measuring the refractive state of the human eye, the optometry instrument relies on high-precision optical components and an intelligent data processing system to accurately capture the optical characteristics of the eye, avoid the bias of human judgment in subjective optometry, and provide core basis for the diagnosis and correction of vision problems. The spherical power it measures can quantify the degree of myopia or hyperopia of the eye, and determine whether correction is needed and the degree of correction. The cylindrical power and optical axis are used for astigmatism problems to determine the degree and direction of astigmatism, respectively, to ensure that the corrective lenses can accurately match the astigmatic area of ​​the eye.

[0003] Traditional refractometers are often bulky and heavy, with a simple fixed structure (such as just a simple headband) and a lack of adjustable support components, making it difficult to stably fit different users' heads. This leads to the device easily shifting during refraction. In addition, changing lenses in traditional devices requires manually removing the old lens and installing the new one, which is cumbersome and time-consuming. Furthermore, manual installation angle deviations may affect the accuracy of refraction. Therefore, there is a need for a head-mounted fully automatic refractometer that is stable and easy to adjust. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a head-mounted fully automatic optometry device that stably fits different users' heads, provides good comfort, is simple and convenient to operate, and has high accuracy.

[0005] The present invention achieves the above objectives by employing the following technical solution:

[0006] A head-mounted fully automatic refractometer is characterized in that it mainly includes a refractometer housing, a fixing rod, a fixing rotating rod, and a built-in refractometer. The refractometer housing has an refractory window and a sliding groove. A chin rest is installed inside the sliding groove.

[0007] The fixed rod is equipped with a vertical plate and a fixed plate. The fixed plate is equipped with an optometry turntable. The optometry turntable is provided with a toothed groove, an arc-shaped locking plate and a locking spring. The optometry turntable is also equipped with an optometry lens. The fixed rotating rod is equipped with a slave toothed plate and a master toothed plate.

[0008] The inner side of the refractometer housing is symmetrically fixedly connected with a fixing plate. The fixing plate is provided with a return spring and a locking plate, which are fixedly connected. The refractometer housing is also provided with an extension plate and an arc-shaped moving plate on both sides. A micro motor is installed on the extension plate. A stop plate is movably connected to the arc-shaped moving plate. When the micro motor is started, it will drive the arc-shaped moving plate to move in a fan shape. The fan-shaped movement of the arc-shaped moving plate will drive the stop plate to move in a fan shape.

[0009] The above technical solution further includes: a one-way lead screw is rotatably connected to the inner side of the sliding groove, and the one-way lead screw is threadedly connected to the cheek rest plate.

[0010] Furthermore, the fixing rod is fixedly connected to the vertical plate, and there are two sets of vertical plates. The vertical plates are fixedly connected to the fixing plate, and the fixing plate is rotatably connected to the optometry turntable.

[0011] Furthermore, the optometry turntable and the bow-shaped locking plate are elastically connected by a locking spring, and the optometry turntable and the optometry lens are detachably assembled and connected.

[0012] Furthermore, there are two sets of fixed rotating rods, which are coaxially and fixedly connected to the driven gear plate and the main gear plate, and are rotatably connected to the optometer housing.

[0013] Furthermore, the fixing plate is fixedly connected to the return spring, and there are two sets of return springs, which are together fixedly connected to the locking plate.

[0014] Furthermore, the refractometer housing is fixedly connected to the extension plate, and there are two sets of extension plates. The extension plate is fixedly connected to the micro motor, and a drive gear is fixedly connected to the end of the output shaft of the micro motor.

[0015] Furthermore, the extension plate is slidably connected to the inside of the bow-shaped movable plate, and multiple sets of trapezoidal grooves are formed on the inner side. The outer side of the bow-shaped movable plate is rotatably connected to a movable shaft, and the outer side of the movable shaft is rotatably connected to a stop plate.

[0016] Furthermore, an elastic headband is fixedly connected to the refractometer housing, and cotton strips and a bonding plate are provided inside the refractometer housing; the refractometer housing is fixedly connected to both ends of the elastic headband, and the outer side of the refractometer housing is fixedly connected to the cotton strips and the bonding plate.

[0017] Furthermore, the inner side of the refractometer housing is fixedly connected to the built-in refractometer, and the refractory hole and the refractory lens provided in the refractometer housing are adapted to each other.

[0018] Furthermore, the built-in optometer is also equipped with a wireless Bluetooth module, a sensor that can intelligently identify the user's eye position and interpupillary distance, and an AI algorithm system module.

[0019] The beneficial effects that can be achieved by adopting the above-mentioned technical solution in this invention are:

[0020] 1. This invention allows the chin rest to be adjusted by a one-way screw to fit the cheeks of different users. The elastic headband, together with the fitting plate and cotton strips, can not only securely fix the refractometer housing, but also reduce the pressure on the head. The backing plate can also share the weight of the device to prevent the head from shaking.

[0021] 2. In this invention, the two sets of fixed rotating rods can rotate separately to independently adjust the corresponding optometry lenses for the left and right eyes, adapting to different refractive power requirements of both eyes. The micro motor can drive the bow-shaped moving plate to automatically fine-tune the angle, adapting to different user head postures without manual adjustment.

[0022] 3. When switching lenses, the toothed disc engages with the toothed groove, causing the refraction turntable to rotate. The locking spring pushes the bow-shaped locking plate, and the reset spring drives the locking cross plate to automatically engage and position the lens, ensuring that the lens is stable in the refraction position.

[0023] 4. This invention can be operated wirelessly and supports Bluetooth connection to a smartphone APP to remotely control the switching of refraction modes, transmit and store data in real time, making it convenient for users to track changes in vision over a long period of time; and it has a built-in high-precision sensor and AI algorithm system module, which can intelligently identify the user's eye position and pupillary distance, automatically calibrate the optical axis center, and improve the accuracy of refraction.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0040] like Figures 1-10 As shown, this invention is a head-mounted fully automatic optometry device, mainly comprising an optometry device housing 1, a fixing rod 3, and a fixing rotating rod 6. The optometry device housing 1 has an optometry window 101 and a sliding groove 102; a chin rest 201 is installed inside the sliding groove 102; a vertical plate 301 and a fixing plate 302 are installed on the fixing rod 3, and an optometry rotating plate 4 is installed on the fixing plate 302. The optometry rotating plate 4 is provided with a toothed groove 401, an arc-shaped locking plate 402, and a locking spring 40. 3. The optometry turntable 4 is equipped with optometry lenses 5, and the fixed rotating rod 6 is equipped with a driven gear 601 and a main gear 602; the inner side of the optometry housing 1 is symmetrically fixedly connected with a fixing plate 7, and the fixing plate 7 is provided with a return spring 701 and a locking horizontal plate 702. The return spring 701 and the locking horizontal plate 702 are fixedly connected. The optometry housing 1 is also provided with a built-in optometry instrument 8, an extension plate 9 and an arc-shaped moving plate 10. The extension plate 9 is equipped with a micro motor 901, and the arc-shaped moving plate 10 is movably connected with a stop plate 1003. When the micro motor 901 is started, it will drive the arc-shaped moving plate 10 to move in a fan shape. The fan-shaped movement of the arc-shaped moving plate 10 will drive the stop plate 1003 to move in a fan shape. The optometry housing 1 is also fixedly connected with an elastic headband 11, and the optometry housing 1 is provided with cotton strips 12 and a bonding plate 13.

[0041] When the user wears the device, the elastic headband 11 secures it to the head, while the cotton strip 12 and the fitting plate 13 enhance wearing comfort. Rotating the one-way screw 2 causes the chin rest 201 to move within the sliding groove 102 to adapt to different users' chin positions. The built-in optometer 8 performs refraction testing through the optometry window 101, while the micro motor 901 drives the bow-shaped moving plate 10 to move in a fan shape, causing the abutment plate 1003 to move synchronously in a fan shape to adapt to the head posture. When switching the refraction lens 5, the fixed rotating rod 6 rotates, and its toothed disc 601 engages with the toothed groove 401 of the refraction turntable 4, causing the refraction turntable 4 to rotate and achieve lens switching. The bow-shaped locking plate 402 and the locking spring 403 lock the refraction turntable 4, and the return spring 701 and the locking cross plate 702 lock the main toothed disc 602 to fix the lens position, thus completing the fully automatic refraction process.

[0042] A one-way lead screw 2 is rotatably connected to the inner side of the sliding groove 102. The one-way lead screw 2 is threadedly connected to the chin rest 201. When the one-way lead screw 2 is rotated, due to its threaded engagement with the chin rest 201, it can drive the chin rest 201 to move along the extension direction of the sliding groove 102. The sliding groove 102 plays a guiding and limiting role in the movement of the chin rest 201, so that the chin rest 201 can be adjusted to fit the user's cheek, thereby stabilizing the user's head posture and adapting to the facial contours of different users.

[0043] The fixing rod 3 is fixedly connected to the vertical plate 301. There are two sets of vertical plates 301. The vertical plates 301 are fixedly connected to the fixing plate 302. The fixing plate 302 is rotatably connected to the optometry turntable 4. The fixing rod 3 provides basic support for the overall structure. The two sets of vertical plates 301 form a stable support structure through their connection with the fixing rod 3, which enhances the support strength of the fixing plate 302. Under the support of the vertical plate 301, the fixing plate 302 provides a rotation reference for the optometry turntable 4, so that the optometry turntable 4 can rotate stably along the fixing plate 302, thereby realizing the position switching of the optometry lens 5 on it and meeting the usage needs of different lenses during the optometry process. The optometry turntable 4 is elastically connected to the bow-shaped locking plate 402 through the locking spring 403. The optometry turntable 4 and the optometry lens 5 are detachably assembled and connected.

[0044] When installing the optometry lens 5, multiple sets of bow-shaped locking plates 402 are compressed. After being subjected to force, the bow-shaped locking plates 402 compress the locking springs 403, causing the locking springs 403 to compress and deform. This causes the bow-shaped locking plates 402 to retract and move, making room for the optometry lens 5 to be inserted. Finally, the optometry lens 5 is successfully inserted into the optometry turntable 4, completing the assembly.

[0045] There are two sets of fixed rotating rods 6. The fixed rotating rods 6 are coaxially and fixedly connected to the slave gear plate 601 and the master gear plate 602. The fixed rotating rods 6 are rotatably connected to the optometry housing 1. The two sets of fixed rotating rods 6 can rotate around the optometry housing 1. When rotating, they drive the coaxially fixed slave gear plate 601 and master gear plate 602 to rotate synchronously. The slave gear plate 601 drives the optometry turntable 4 to rotate to switch the optometry lens 5 through meshing transmission. The master gear plate 602 cooperates with the locking component to achieve rotation positioning. The two sets of fixed rotating rods 6 correspond to the double-sided optometry structure respectively and can be operated independently to adapt to the different optometry needs of the left and right eyes.

[0046] The fixing plate 7 is fixedly connected to the return spring 701. There are two sets of return springs 701, and both sets of return springs 701 are fixedly connected to the locking plate 702. The fixing plate 7 provides a mounting support base for the return springs 701 and the locking plate 702. When the fixing rod 6 drives the main gear plate 602 to rotate to adjust the position of the optometry lens 5, the main gear plate 602 will push the locking plate 702, causing the two sets of return springs 701 to compress and deform synchronously. When the main gear plate 602 rotates to the target position corresponding to the required position of the optometry lens 5, the pushing force of the main gear plate 602 on the locking plate 702 disappears, and the two sets of return springs 701 return to their elastic state, causing the locking plate 702 to engage with the main gear plate 602, thereby locking the position of the main gear plate 602 and the fixing rod 6, ensuring that the optometry lens 5 is stably in the working state.

[0047] The refractometer housing 1 is fixedly connected to the extension plate 9. There are two sets of extension plates 9. The extension plate 9 is fixedly connected to the micro motor 901. The output shaft end of the micro motor 901 is fixedly connected to the drive gear 902.

[0048] The refractometer housing 1 provides a basic fixed support for the extension plate 9. The two sets of extension plates 9 correspond to the double-sided structure of the device, ensuring that the installation position of the micro motor 901 is symmetrical and stable. When it is necessary to adjust the fit between the head and the refractometer, the micro motor 901 starts, and its output shaft drives the drive gear 902 to rotate synchronously. The drive gear 902 further meshes with the trapezoidal groove 1001 of the bow-shaped moving plate 10 to provide power for the fan-shaped movement of the bow-shaped moving plate 10. Then, through the synchronous movement of the abutment plate 1003, the head posture is adapted and adjusted, ensuring the stability of the head position during the refraction process.

[0049] The extension plate 9 is slidably connected to the inside of the bow-shaped movable plate 10. Multiple trapezoidal grooves 1001 are provided on the inner side of the 10. A movable shaft 1002 is rotatably connected to the outer side of the bow-shaped movable plate 10. The outer side of the movable shaft 1002 is rotatably connected to the abutment plate 1003.

[0050] When the micro motor 901 drives the drive gear 902 to mesh with the multiple trapezoidal grooves 1001 on the inner side of the bow-shaped moving plate 10, the bow-shaped moving plate 10 slides along the inside of the extension plate 9. The extension plate 9 provides guidance and limitation for it. The movable shaft 1002 on the outer side of the bow-shaped moving plate 10 moves with it. The rotational connection between the movable shaft 1002 and the abutment plate 1003 allows the abutment plate 1003 to adaptively conform to the user's body. The abutment plate 1003 forms a support point by abutting against the user's body, transferring part of the weight of the optometer to the body, thereby sharing the weight of the optometer on the head, reducing the pressure on the head, avoiding head fatigue caused by wearing it for a long time, and further stabilizing the head position to ensure the accuracy of the optometry process.

[0051] The optometry device housing 1 is fixedly connected to the elastic headband 11 at both ends. The outer side of the optometry device housing 1 is fixedly connected to the cotton strip 12 and the bonding plate 13. When the user wears the optometry device, the elastic headband 11 connected to both ends of the optometry device housing 1 can conform to the contour of the head through its own elasticity, so as to stably fix the optometry device housing 1 on the head and prevent the device from shifting during the optometry process. The bonding plate 13 on the outer side of the optometry device housing 1 will first contact the head skin to ensure the fitting accuracy between the housing 1 and the head, and provide a stable position reference for the optometry test. The cotton strip 12 is attached between the bonding plate 13 and the head, which can buffer the pressure of the bonding plate 13 on the head, reduce the discomfort of wearing for a long time, and further ensure the stability of the user's head during the optometry process, and ensure the accuracy of the optometry data.

[0052] The inner side of the refractometer housing 1 is fixedly connected to the built-in refractometer 8, and the size of the refractory aperture of the refractory housing 1 is adapted to the size of the refractory lens 5. The built-in refractometer 8 is also equipped with a sensor and AI algorithm system module that can intelligently identify the user's eye position and pupillary distance. The refractometer housing 1 provides a stable mounting base for the built-in refractometer 8, ensuring that its position is fixed during the refraction process. When the refraction turntable 4 drives the refractory lens 5 to rotate to the working position, the refractory aperture of the refractory housing 1, because it is adapted to the size of the refractory lens 5, allows the lens 5 to cover the refractory aperture, ensuring that light or detection signals can be stably transmitted to the built-in refractometer 8 through the lens 5 and the refractory aperture. The built-in refractometer 8 then processes and analyzes the light or signal, intelligently identifies the user's eye position and pupillary distance, automatically calibrates the optical axis center, and completes the acquisition and detection of refraction data. The built-in refractometer 8 is also equipped with a wireless Bluetooth module, which can realize connection with a mobile smart APP and remote control operation.

[0053] When worn by the user, the elastic headband 11 fixes the optometry device housing 1 to the head, the cotton strip 12 and the fitting plate 13 improve wearing comfort, and the rotation of the one-way screw 2 drives the chin support plate 201 to move along the sliding groove 102 to fit the cheek and stabilize the head; the fixing rod 3 supports the fixing plate 302 through two sets of vertical plates 301, and the optometry turntable 4 can rotate along the fixing plate 302. When installing the optometry lens 5, multiple sets of bow-shaped locking plates 402 are squeezed to compress the locking spring 403 to embed it.

[0054] When switching lenses, the two sets of fixed rotating rods 6 rotate around the optometry housing 1, driving the coaxial driven toothed disc 601 to mesh with the tooth groove 401 of the optometry turntable 4 to rotate. At the same time, the main toothed disc 602 pushes the locking plate 702 to compress the two sets of return springs 701 on the fixed plate 7. After reaching the position, the return springs 701 drive the locking plate 702 to engage the main toothed disc 602. The bow-shaped locking plate 402 locks the optometry turntable 4 under the action of the locking spring 403 to fix the lenses.

[0055] The micro motor 901 is fixed by the extension plate 9. Its output shaft drives the drive gear 902 to mesh with the trapezoidal groove 1001 of the bow-shaped moving plate 10, so that the bow-shaped moving plate 10 slides along the extension plate 9. The outer movable shaft 1002 drives the abutment plate 1003 to adapt to the body and share the weight.

[0056] Finally, the built-in refractometer 8 receives signals through the refractory window 101 and the refractory aperture adapted to the refractory lens 5, and processes them through the sensor and AI algorithm system module to complete fully automatic refraction.

[0057] The outside of the refractometer housing can also be equipped with a bracket or head cover to cover the entire structure, hiding the entire internal refractometer housing structure inside, forming an integrated structure.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, such as using a helmet-style outer cover, etc., and these all fall within the protection scope of the present invention.
