DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 , a pair of glasses that can adapt to myopia and hyperopia, including a frame 1, two nose pads 3 are provided on the frame 1, and the two nose pads 3 are integrally formed with the frame 1; two temples 2 are hingedly connected to the frame 1, and hinges are embedded in the temples 2, and the hinges are embedded in the frame 1.

[0027] The ear bend 5 is detachably connected to the temple 2, and wedge-shaped blocks 16 are fixed to the inner top and inner bottom of the mounting cavity 11. An L-shaped buckle 17 is fixed to the ear bend 5, and the L-shaped buckle 17 is abutted against and buckled on the wedge-shaped block 16. The L-shaped buckle 17 and the ear bend 5 are injection-molded as one piece. Both the L-shaped buckle 17 and the ear bend 5 are made of rubber. The L-shaped buckle 17 is provided with an inclined surface, which is cooperated with the wedge-shaped block 17. The L-shaped buckle 17 can be removed by pulling it to separate it from the wedge-shaped block 16, so as to facilitate maintenance of the power supply 15 and the like.

[0028] A hard convex lens 4 and a soft lens 6 are installed in the frame 1. An annular groove is provided on the inner side of the frame 1, and an extrusion tube 12 surrounding the outside of the soft lens 6 is installed in the annular groove, so that a soft connection is formed between the hard convex lens 4 and the soft lens 6. The soft lens 6 is made of resin material and has good ductility; an annular groove is provided on the inner side of the frame 1, and an extrusion tube 12 surrounding the outside of the soft lens 6 is installed in the annular groove; a mounting cavity 11 is provided in the temple 2, and a liquid pressure pump 7 is installed in the mounting cavity 11. The liquid pressure pump 7 is connected to the extrusion tube 12 through a hose 18. A through groove 10 communicating with the mounting cavity 11 is provided on the temple 2, and the hose 18 is arranged through the through groove 10.

[0029] A liquid storage tank 9 is installed in the installation cavity 11, and a connecting pipe 8 is installed on the liquid pressure pump 7, which is connected to the liquid storage tank 9. A power supply 15 is installed in the installation cavity 11, and the power supply 15 is connected to the liquid pressure pump 7. A first control switch 13 and a second control switch 14 connected to the power supply 15 and the liquid pressure pump 7 are installed on the temple 2. The first control switch 13 controls the liquid pressure pump 7 to transport the liquid in the liquid storage tank 9 to the squeeze tube 12. The first control switch 13 has multiple gears. Each time it is pressed, the moving liquid will be transported to the squeeze tube 12, so that the squeeze tube 12 expands and squeezes the soft lens 6 to deform, and the degree of deformation each time is 25 degrees; the second control switch 14 controls the liquid pressure pump 7 to transport the liquid in the squeeze tube 12 to the liquid storage tank 9. As mentioned above, the degree of deformation each time is also 25 degrees.

[0030] The liquid pressure pump 7 delivers liquid into the squeeze tube 12 to expand the squeeze tube 12. The expansion of the squeeze tube 12 squeezes the soft lens 6 to make it convex, turning it into a myopia lens; when the soft lens 6 is flat, the hard convex lens 4 and the soft lens 6 form a convex lens for hyperopia users. In this way, it is only necessary to control the amount of liquid in the squeeze tube 12 to drive the soft lens 6 to deform, so as to achieve the overall thickness of the convex lens and the concave lens, and realize the adjustment of the myopia degree and hyperopia degree.

[0031] It also includes a control system, which includes a microcontroller, a voltage sensor, and a current sensor. The first control switch 13 and the second control switch 14 are connected to the microcontroller, the voltage sensor and the current sensor are connected, and the power supply 15 is connected to the voltage sensor and the current sensor.

[0032] Working principle of liquid pressure pump:

[0033] Liquid delivery process: Liquid pressure pump 7 utilizes a miniature electric diaphragm pump structure. An internal motor drives the rotation of an eccentric, which in turn drives the reciprocating motion of the diaphragm. When the diaphragm moves backward, negative pressure forms within the pump chamber. This pressure differential draws liquid from reservoir 9 into the pump chamber through connecting tube 8. When the diaphragm moves forward, pressure within the pump chamber increases, squeezing the liquid and delivering it through flexible tube 18 to extrusion tube 12. A one-way valve within the pump ensures one-way flow of liquid, preventing backflow.

[0034] Liquid Retraction: When the second control switch 14 is triggered, the motor of the liquid pressure pump 7 rotates in reverse, driving the eccentric to rotate in the opposite direction, changing the direction of movement of the diaphragm. At this point, the liquid in the extrusion tube 12 is drawn back into the pump chamber through the hose 18 under the influence of the negative pressure in the pump chamber, and then flows back into the liquid storage tank 9 through the connecting pipe 8.

[0035] Soft lens deformation principle:

[0036] Myopia Correction: When the first control switch 13 is pressed, the liquid pressure pump 7 activates, pumping the liquid from the liquid reservoir 9 into the squeeze tube 12. As the amount of liquid in the squeeze tube 12 increases, the squeeze tube 12 expands. Because it surrounds the outside of the soft lens 6, the expanded squeeze tube 12 applies uniform radial pressure to the soft lens 6, causing it to bulge toward the center, forming a concave lens structure for myopia correction. Because the soft lens 6 is made of a resin material with excellent ductility, it can deform under the pressure of the squeeze tube 12. The first and second control switches 13, 14 are mounted on each temple 2. Therefore, the corresponding switches can be adjusted according to the different prescriptions of the glasses to control the state of the soft lens 6 and meet the user's needs.

[0037] Hyperopia Accommodation: When the soft lens 6 is in a flat position, the hard convex lens 4 and the soft lens 6 together form a convex lens structure suitable for users with hyperopia. To return from myopia accommodation to hyperopia or further adjust the hyperopia, the second control switch 14 is pressed, and the liquid pressure pump 7 pumps the liquid in the squeeze tube 12 back into the liquid reservoir 9. The squeeze tube 12 contracts, reducing the pressure on the soft lens 6. The soft lens 6 gradually returns to a flat position or adjusts to the desired hyperopia due to its own elasticity.

[0038] control system

[0039] Control switch: The first control switch 13 and the second control switch 14 are micro switches with high sensitivity and easy operation. They are connected to the power supply 15 and the liquid pressure pump 7 respectively, and the corresponding control signal is triggered by pressing the switch.

[0040] Power Management Module: Power supply 15 is a rechargeable lithium battery installed in the mounting cavity 11 of the temple 2. The power management module is responsible for battery charge management, voltage monitoring, and battery level display. When the battery level is low, the power management module issues a warning signal, reminding the user to recharge. It also ensures a stable voltage supply to the hydraulic pressure pump 7 under various operating conditions, ensuring proper operation.

[0041] Drive Circuit: This circuit receives signals from the control switch and converts them into electrical signals that drive the motor of the liquid pressure pump 7. The drive circuit utilizes an H-bridge drive circuit, enabling forward and reverse rotation of the motor, thereby controlling the direction of liquid delivery and withdrawal. The drive circuit also features overcurrent and overvoltage protection to prevent damage to the motor due to excessive current or voltage.

[0042] Initialization: After the system is powered on, the microcontroller performs initialization operations, including testing each hardware module and setting the initial state of the control switch. At the same time, it reads the power information of the power management module and displays the power status when necessary.

[0043] Control Logic of First Control Switch 13: When the first control switch 13 is pressed, the microcontroller detects the switch signal and, based on the current gear position, controls the drive circuit to rotate the motor of the liquid pressure pump 7 forward, delivering liquid into the extrusion tube 12. Each time the switch is pressed, the microcontroller records the gear position change and controls the liquid pressure pump 7 to deliver a certain amount of liquid, causing the soft lens 6 to deform by 25 degrees. Once the maximum gear position is reached, pressing the switch again will no longer increase the liquid delivery rate.

[0044] Control Logic of Second Control Switch 14: When the second control switch 14 is pressed, the microcontroller detects the switch signal and controls the drive circuit to reverse the motor of the liquid pressure pump 7, pumping the liquid in the squeeze tube 12 back into the liquid reservoir 9. Similarly, each time the switch is pressed, the microcontroller controls the liquid pressure pump 7 to pump back a certain amount of liquid, restoring the 25-degree deformation of the soft lens 6. When the soft lens 6 returns to a flat state or reaches its minimum position, pressing the switch again stops pumping liquid.

[0045] Fault Detection and Handling: The microcontroller monitors the operating status of the hydraulic pressure pump 7 in real time, such as current, voltage, and other parameters. If an abnormality is detected, such as excessive current or low voltage, the microcontroller immediately stops the hydraulic pressure pump 7 and alerts the user through indicators or sounds of possible faults, such as liquid leakage or motor damage, so that the user can promptly perform repairs or other actions.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
