Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic instruments, in particular to a pair of zoom glasses. Background Art

[0002] Varifocal glasses are specially designed glasses that simulate the natural adjustment process of the eyes when observing at different distances, near and far, by equipping them with multifocal lenses (including fixed lenses and moving lenses) with continuously changing focal lengths. The design of these glasses allows the wearer's ciliary muscles to be effectively exercised when observing distant and close objects, helping to enhance their adjustment ability, which may have a positive effect on improving vision and reducing visual fatigue. Varifocal glasses are a useful visual aid for people who need to work or read at close range for a long time, and for those who hope to improve the eye's adjustment function through training.

[0031] Varifocal glasses are specially designed glasses that simulate the natural adjustment process of the eyes when observing at different distances, near and far, by equipping them with multifocal lenses (including fixed lenses and moving lenses) with continuously changing focal lengths. The design of these glasses allows the wearer's ciliary muscles to be effectively exercised when observing distant and close objects, helping to enhance their adjustment ability, which may have a positive effect on improving vision and reducing visual fatigue. Varifocal glasses are a useful visual aid for people who need to work or read at close range for a long time, and for those who hope to improve the eye's adjustment function through training.

[0032] Since varifocal glasses integrate a lot of electronic components to realize different functions of varifocal glasses, they are heavy. In related technologies, electronic components are integrated inside the frames, which will cause the center of gravity of the entire device to be unbalanced and press on the nose pads. This will make the user feel greater pressure on the nose bridge after wearing it, making it uncomfortable to wear. In addition, since the center of gravity is concentrated on the front part of the glasses, when the user lowers his head, the glasses are easy to slide down or even fall off, affecting the user's use.

[0033] In order to solve the above problems, the utility model proposes a pair of zoom glasses, aiming to provide a pair of zoom glasses that can significantly improve the wearing comfort of users and thus optimize the user experience. Figures 1 to 6 The figure is a schematic structural diagram of an embodiment of the variable focus glasses provided by the present utility model.

[0034] Please refer to Figures 1 to 6 The utility model proposes a zoom glasses 1000, including a frame and two temples 3. The frame is formed with a first accommodating cavity, the first accommodating cavity is provided with a main control board, a fixed lens 21 is provided on one side of the frame, two movable lenses 22 are movably provided on one side of the fixed lens 21, the first accommodating cavity is provided with a driving component, the driving component is electrically connected to the main control board and is used to drive the two movable lenses 22 to move closer to or away from each other, the two temples 3 are rotatably arranged at the two ends of the frame, the end of the temple 3 away from the frame is provided with an energy storage component, and the energy storage component is electrically connected to the main control board and the driving component.

[0035] The technical solution of the utility model proposes a zoom glasses 1000. Specifically, the zoom glasses 1000 include a frame and two temples 3. The frame is formed with a first accommodating cavity, the first accommodating cavity is provided with a main control board, a fixed lens 21 is provided on one side of the frame, two movable lenses 22 are movably provided on one side of the fixed lens 21, the temples 3 are rotatably provided at both ends of the frame, and an energy storage component is provided at one end of the temple 3 away from the frame, and the energy storage component is electrically connected to the main control board and the driving component. By arranging the energy storage component in the temple 3 and at the end away from the frame, the arrangement of components in the frame can be reduced, so that the overall center of gravity of the glasses is moved backward, the pressure on the bridge of the nose after long-term use is alleviated, and the user is not easy to feel fatigue or discomfort when wearing for a long time. In addition, by integrating the energy storage component at the rear end of the temple 3, the inconvenience caused by the glasses easily slipping when the user lowers his head can also be avoided.

[0036] The zoom glasses 1000 are provided with a switch key 111 and a mode adjustment key 112. For details, please refer to Figure 1 The mode adjustment key 112 can adjust different modes of the glasses. The front shell 11 is also provided with a power indicator 113 to display the remaining power of the device. The top of the frame is provided with a Type-C charging port 114 to recharge the device. The top of the frame is also provided with a mute key 115, which can mute the sound output component with one key. To support the glasses, a nose pad is provided in the middle of the frame, and the nose pad adopts a detachable design.

[0037] In one embodiment of the present invention, the energy storage component generally adopts a lithium battery. Lithium batteries have a high energy density, which means that they can provide more electrical energy in the same volume, and are very suitable for wearable devices such as smart glasses that have strict requirements on space and weight. Secondly, lithium batteries have a low self-discharge rate and can maintain a long battery life even when not in use for a long time. Furthermore, lithium batteries have a long cycle life and can withstand multiple charge and discharge processes, thereby extending the service life of smart glasses. In addition, lithium batteries also have fast charging capabilities, which reduces charging waiting time and improves user experience. Finally, lithium batteries have relatively high chemical stability and safety, providing reliable power guarantee for smart glasses. To facilitate the assembly of the battery and subsequent maintenance and replacement, the temple 3 includes a temple 3 arm and a support portion. For details, please refer to Figure 2, the temple 3 arms and the support part are spliced ​​by snap-fit ​​assembly. The ends of the temple 3 arms and the support part are provided with a second accommodation cavity for battery installation. The temple 3 arms are hollow inside to ensure the connection between the first accommodation cavity and the second accommodation cavity. The internal wiring of the temple 3 arms connects the battery and the main control board and the drive assembly respectively. Since the battery is placed at the rear of the design, the size of the battery can be increased, and there will be no limitation on the position of other electronic components, which can extend the overall endurance of the device. When the battery is discharged to the outside, the internal resistance may cause the battery to heat up. Placing the battery at the rear can reduce the adverse effects of battery heating on the components in the frame, and can also prevent heat radiation from damaging the human face. In addition, the support part is bent downward, so that the setting can better adapt to the ear contour of the wearer, provide stable support and comfortable fit. When the end of the temple 3 matches the curve of the ear, the glasses can be reduced from sliding or shifting, ensuring that the glasses stay firmly on the bridge of the nose. In addition, this design also helps to disperse the pressure of the glasses on specific contact points to avoid discomfort or indentation caused by long-term wear.

[0038] Furthermore, the material of the temple 3 is TR90 composite material. TR90 is a lightweight material that hardly causes a sense of oppression to the user when worn, significantly improving the comfort of long-term wearing. Secondly, this material has excellent memory and can bend and adjust appropriately according to the user's head shape to maintain the stability of the frame. In addition, TR90 material also has good elasticity and toughness, making it more impact-resistant and less prone to damage. At the same time, it also has good chemical stability and corrosion resistance, making it suitable for use in various environments.

[0039] In the technical solution of the present utility model, in order to enhance the user's experience, the zoom glasses 1000 also include a sound output component. For details, please refer to Figure 4 and Figure 6 The sound output component is arranged in the first receiving cavity and at both ends of the frame. The two sides are symmetrically arranged to ensure sound balance. The frame is formed with a sound output port 121 relative to the sound output component. The sound output port 121 is arranged toward the user's head. The sound output component creates a more relaxing and pleasant training environment through music and sound prompts; secondly, sound prompts can assist visual training and help users adjust the focal length more accurately, especially when performing zoom exercises. Sound feedback can guide users to focus on a specific visual distance and improve training effects; thirdly, the integrated speaker provides a convenient way of interaction. Users can receive information and instructions directly through the glasses without using mobile phones or other devices; in addition, this design may also include personalized audio feedback, such as training progress updates, encouraging prompts or relaxation guidance, which helps to increase user participation and motivation.

[0040] In order to prevent the user from causing adverse damage to the user's eyes when the user uses the zoom glasses 1000 due to the viewing distance being too close or too far, the zoom glasses 1000 also include a distance measuring sensor. For details, please refer to Figure 1 The distance measuring sensor is arranged in the first receiving cavity and exposed on the side of the frame facing away from the temple 3. It should be noted that the distance measuring sensor adopts a TOF (Time of Flight) distance measuring sensor. The working principle of the TOF distance measuring sensor is based on measuring the time required for a light pulse to be emitted from a transmitter, reflected back and received by a receiver. This sensor first emits a short and intense light pulse (usually infrared light). When this light pulse encounters the surface of an object, part of the light will be reflected back. The receiver measures the time required for the light pulse to be emitted and returned. Since the speed of light is known, the distance between the sensor and the object, that is, the distance between the user's eyes and the desktop, book, display device, etc., can be determined by calculating the round-trip time.

[0041] In order to install the components in the frame, the frame includes a front shell 11 and a rear shell 12, both of which are made by injection molding. The front shell 11 and the rear shell 12 enclose a first accommodating cavity. When the internal components need to be installed or removed, the front and rear shells 12 can be separated. In order to ensure the sealing inside the first accommodating cavity and prevent the components from being damaged, the gap between the front shell 11 and the rear shell 12 is sealed with a sealant. Two hinged parts extend from both ends of the rear shell 12 and are hingedly connected to the two temples 3.

[0042] In order to realize the rapid disassembly and assembly of the fixed lens 21, a plurality of mounting openings are provided on the side of the front shell 11 and the rear shell 12 facing the fixed lens 21. In one embodiment of the utility model, there are two left-right symmetrical fixed lenses 21. Two clamping blocks are provided on the upper edge of each fixed lens 21. The clamping blocks extend into the first accommodating cavity. Each clamping block is crimped with a pressing block 123 to realize fixation. To realize the disassembly of the fixed lens 21, it is only necessary to loosen the screws used to connect the front shell 11 and the rear shell 12, so that the front shell 11 and the rear shell 12 can be opened to a certain distance, thereby removing the pressing block 123, and then removing the fixed lens 21.

[0043] In order to train the user's ciliary muscles, this technical solution uses movable lenses to change the focal length to adapt to targets at different viewing distances. The principle is based on simulating the natural adjustment process of the eyes when looking at objects at different distances. This type of glasses is equipped with special lenses that allow the user to change the focal length by adjusting the distance between lenses or changing the refractive index of the lenses to adapt to targets at different viewing distances. When using the zoom glasses 1000, the wearer's line of sight switches between distant and near views, prompting the ciliary muscles to constantly adjust to different viewing distances. Such exercises help to strengthen the strength and flexibility of the ciliary muscles, improve the eye's ability to adjust, and reduce visual fatigue caused by long-term focusing. In order to achieve adjustable focal length, the zoom glasses 1000 also include a slider 124. The slider 124 is limited in sliding to the frame and is driven by a motor 125. For details, please refer to further. Figure 4 and Figure 5 A magnetic conductive member 127 is disposed on the slider 124, and a magnetic member 126, such as a magnet, is disposed at one end of the movable lens 22. The movable lens 22 is fixed to the slider 124 by magnetic attraction, so that quick disassembly, assembly and replacement can be achieved.

[0044] In order to make the device more integrated and the structure more compact, the zoom glasses 1000 also include a connector, which is used for signal transmission to achieve interconnection between the glasses and the terminal device. The connector is arranged in the first receiving cavity and is connected to the main control board through a flexible cable, so that the structures can be stacked, making the structures more compact and the layout more reasonable.

[0045] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
