Description

Technical Field

[0001] This invention relates to the technical field of smart glasses, and in particular to the technical field of smart glasses with adjustable width. Background Technology

[0002] As a new type of smart wearable device, smart glasses have not yet achieved widespread adoption and tend to be shared in family settings, often with adults and children sharing the same pair. However, different groups of people have significant differences in head shape, facial proportions, interocular distance, interauricular distance, and interocular-ear distance. Most existing smart glasses frames are of fixed size, and even the few adjustable models only offer a single overall width adjustment, failing to allow for independent adjustment of interocular and interauricular distances, making it difficult to meet the personalized wearing needs of different users within a family.

[0003] If smart glasses are designed to fit children's head sizes, the frames will be too small for adults, causing severe deformation. This not only results in excessive pressure and poor comfort but also damages the frame structure and internal electronic components, affecting the lifespan of the smart glasses. Conversely, if designed for adults, children may experience loose frames that slip off easily. Misalignment between the lenses and pupils can also affect the glasses' performance and pose safety hazards due to instability. Furthermore, some existing adjustable glasses only adjust the temple spacing, failing to accommodate the longer interocular distance of people with larger heads. Even after adjustment, temple pressure on the temples and discomfort persist, further limiting the family compatibility of smart glasses. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an adjustable-width smart glasses. This solves the problems of fixed frames not being able to fit people with different head shapes, single adjustment structures not being able to meet the needs of eye distance and ear distance adjustment respectively, and the tendency for the glasses to become loose or not fully fit after adjustment in a shared home setting.

[0005] To achieve the above objectives, the present invention proposes an adjustable-width smart glasses, comprising two single lens frames, an eye distance adjustment mechanism, an ear distance adjustment fixed seat, an ear distance adjustment movable seat, a positioning mechanism, and temples. An eye distance adjustment mechanism for adjusting the distance between the two single lens frames is provided between the single lens frames and the temples. An ear distance adjustment fixed seat and an ear distance adjustment movable seat are provided between the single lens frames and the temples for adjusting the distance between the two temples and the appropriate temple length by sliding outwards and backwards. The ear distance adjustment fixed seat and the ear distance adjustment movable seat are slidably disposed relative to each other. A positioning mechanism for positioning the ear distance adjustment movable seat is provided on the ear distance adjustment fixed seat. Preferably, an elastic sheet is provided on the front side between the two single lens frames to block the interpupillary distance adjustment mechanism and automatically expands and contracts with the change in the distance between the two single lens frames. Preferably, the single lens frame and the temple are provided with a fixed ear distance adjustment seat and a movable ear distance adjustment seat for adjusting the gap between the two temples by sliding outward and backward. Preferably, the interpupillary distance adjustment mechanism includes an interpupillary distance adjustment sleeve, an interpupillary distance adjustment screw, and an interpupillary distance adjustment manual wheel. The interpupillary distance adjustment sleeve is fixed to a single lens frame, and the two ends of the interpupillary distance adjustment screw are respectively threaded to the interpupillary distance adjustment sleeves on two single lens frames. The interpupillary distance adjustment manual wheel is provided in the middle of the interpupillary distance adjustment screw. Preferably, the device also includes an interpupillary distance adjustment guide rod, the two ends of which are slidably inserted into the two single lens frames. Preferably, the fixed ear distance adjustment seat is provided with an ear distance adjustment guide rail that is inclined outward at the rear end; the movable ear distance adjustment seat is provided with an ear distance adjustment guide rail, and the fixed ear distance adjustment guide rail and the movable ear distance adjustment guide rail are opposite each other so that the temple of the glasses slides outward and backward.

[0006] Preferably, the positioning mechanism includes a positioning hand-tightening column and a positioning screw. One end of the positioning screw is fixed with the positioning hand-tightening column for hand rotation, and the other end passes through a screw hole on the ear distance adjustment guide rail, with the end abutting against the ear distance adjustment moving guide rail.

[0007] The beneficial effects of this invention are as follows: This invention precisely adjusts the distance between the two single lens frames through the interpupillary distance adjustment mechanism to adapt to the interpupillary distance of different users and ensures accurate alignment between the lens and the pupil; it adjusts the distance between the temples of the glasses by the relative sliding of the fixed and movable ear distance adjustment seats to adapt to the interauricular distance of different users, so that the frame fits the head. Both the interpupillary distance and ear distance are adjustable, which can meet the wearing needs of adults, children and other people with different head shapes in the family, and greatly improve the versatility of smart glasses.

[0008] The dual-adjustment structure is simple to operate and has a firm positioning. The positioning mechanism after ear distance adjustment can effectively fix the position of the ear distance adjustment seat, preventing the smart glasses from automatically loosening or shifting due to shaking or squeezing during wear, ensuring wearing stability and convenient operation.

Detailed Implementation

[0011] See Figure 1This invention discloses an adjustable-width smart glasses, comprising two single-lens frames 1, an eye distance adjustment mechanism 2, an ear distance adjustment fixed seat 3, an ear distance adjustment movable seat 4, a positioning mechanism 5, and temples 6. The eye distance adjustment mechanism 2 is disposed between the two single-lens frames 1 for adjusting the distance between them. The ear distance adjustment fixed seat 3 and the ear distance adjustment movable seat 4 are disposed between the single-lens frames and the temples for adjusting the distance between the two temples and the appropriate temple length by sliding them outwards and backwards. The ear distance adjustment fixed seat 3 and the ear distance adjustment movable seat 4 are slidably disposed relative to each other. The ear distance adjustment fixed seat 3 is provided with a positioning mechanism 5 for positioning the ear distance adjustment movable seat 4. Because different people have different head sizes, the relative eye distance... The distance between the eyes and the ears is different and requires relative adjustment. Currently, adjustable glasses on the market only have one adjustment method. After adjusting to meet the gap between the eyes, it is not possible to adjust the gap between the ears separately. As a result, although the width of the existing glasses can be adjusted, the relative position between the lens and the eyes cannot be adjusted to a suitable position after adjustment, and it cannot meet the adjustment needs of the gap between the ears and the gap between the eyes at the same time. This application can adjust the distance between the two single lens frames 1 through the eye distance adjustment mechanism 2, and can adjust the distance between the two temples 6 through the ear distance adjustment fixed seat 3 and the ear distance adjustment movable seat 4. It can well meet the needs of adjusting the gap between the ears and the gap between the eyes separately, and the adjustment is simple and aesthetically pleasing. Smart glasses differ from traditional glasses. Traditional glasses are generally for individual use only, but smart glasses can be shared by multiple family members. Especially since smart glasses are not yet widely available, they are more likely to be used together within a family. However, adults and children have different requirements for the size of the glasses. If smart glasses are designed for children, adults may experience significant deformation, which can be uncomfortable or even damage the glasses. Conversely, if children wear glasses that are too large, they may not fit securely and may also feel uncomfortable.

[0012] In this embodiment, to make the glasses more aesthetically pleasing overall, such as... Figure 1 and Figure 2 An elastic sheet 7 is provided on the front side between the two single lens frames 1 to block the interpupillary distance adjustment mechanism 2 and automatically expands and contracts with the change of the distance between the two single lens frames 1. The elastic sheet 7 is made of elastic rubber. When adjusting the two single lens frames 1, the elastic sheet 7 stretches as the distance increases and shrinks as the distance decreases.

[0013] In this embodiment, as Figures 4-7Between the single lens frame 1 and the temple 6, there is an ear-distance adjustment fixed seat 3 and an ear-distance adjustment movable seat 4 for adjusting the gap between the two temples 6 by sliding them outward and backward. By sliding the ear-distance adjustment movable seat 4 relative to the ear-distance adjustment fixed seat 3 outward and backward, the length of the temples 6 is adjusted at the same time as the gap between them, accommodating the increased gap between the eyes and ears of people with relatively larger heads. Different people have different head sizes. People with larger heads are more likely to have a larger distance between their eyes, a larger distance between their ears, and a larger distance between their ears and eyes. Therefore, simply adjusting the width between the temples 6 cannot truly meet the various size requirements corresponding to different head shapes. like Figure 2 and Figure 3 The interpupillary distance adjustment mechanism 2 includes an interpupillary distance adjustment sleeve 21, an interpupillary distance adjustment screw 22, an interpupillary distance adjustment guide rod 24, and an interpupillary distance adjustment manual wheel 23. The interpupillary distance adjustment sleeve 21 is fixed to a single lens frame 1. The two ends of the interpupillary distance adjustment screw 22 are threadedly connected to the interpupillary distance adjustment sleeves 21 on two single lens frames 1, respectively. The interpupillary distance adjustment manual wheel 23 is located in the middle of the interpupillary distance adjustment screw 22. By manually rotating the interpupillary distance adjustment manual wheel 23, the interpupillary distance adjustment screw 22 is driven to rotate, and finally, the interpupillary distance adjustment screw 22 and the interpupillary distance adjustment sleeve 21 cooperate to adjust the distance between the two single lens frames 1. The two ends of the interpupillary distance adjustment guide rod 24 are slidably inserted into the two single lens frames 1. In order to prevent the two single lens frames 1 from flipping relative to each other in the front-back direction, the interpupillary distance adjustment guide rod 24 cooperates with the interpupillary distance adjustment screw 22 to provide two rotatable axes between the two single lens frames 1, thus preventing the two single lens frames 1 from flipping relative to each other in the front-back direction.

[0014] Specifically, such as Figures 4-7 The ear-distance adjustment base 3 is equipped with an ear-distance adjustment guide rail 31 that tilts outward at the rear end; the ear-distance adjustment movable base 4 is equipped with an ear-distance adjustment movable guide rail 41. The ear-distance adjustment guide rail 31 and the ear-distance adjustment movable guide rail 41 are positioned opposite each other to allow the temples 6 to slide outward and backward. By allowing the ear-distance adjustment guide rail 31 and the ear-distance adjustment movable guide rail 41 to slide outward and backward relative to each other, the purpose of sliding the temples 6 outward and backward is achieved, thus adjusting both the distance between the two temples 6 and the length of the temples 6, to accommodate the increased gap between the eyes and ears of people with relatively larger heads. Figures 4-7The positioning mechanism 5 includes a positioning hand-tightening column 51 and a positioning screw 52. One end of the positioning screw 52 is fixed to the positioning hand-tightening column 51 for hand rotation, and the other end passes through a screw hole on the ear distance adjustment guide rail 31, with the end abutting against the ear distance adjustment moving guide rail 41. When it is necessary to adjust the gap between the two temples 6, the positioning screw 52 is loosened, allowing the ear distance adjustment moving guide rail 41 to slide relative to the ear distance adjustment guide rail 31. When the position is in place, the positioning screw 52 is turned, causing the end of the positioning screw 52 to pass through the ear distance adjustment guide rail 31 and press against the ear distance adjustment moving guide rail 41, preventing the ear distance adjustment moving guide rail 41 from moving relative to the ear distance adjustment guide rail 31 and avoiding the glasses from automatically loosening when worn.

[0015] The working process of this invention: In this invention, adjustable-width smart glasses, when interpupillary distance adjustment is needed, are operated by pinching the interpupillary distance adjustment manual wheel 23 and rotating it clockwise / counterclockwise. This causes the interpupillary distance adjustment screw 22 to rotate synchronously. Because the external threads at both ends of the screw, with opposite directions of rotation, engage with the interpupillary distance adjustment screw sleeve 21 on the single lens frame 1, the two single lens frames 1 will slide towards or away from each other along the interpupillary distance adjustment guide rod 24, achieving fine adjustment of the distance between the two single lens frames 1. During the adjustment process, the elastic rubber sheet 7 between the single lens frames 1 automatically expands and contracts with the change in distance. When the distance increases, the elastic sheet 7 is stretched evenly; when the distance decreases, the elastic sheet 7 naturally contracts, always blocking the internal interpupillary distance adjustment mechanism 2. At the same time, the interpupillary distance adjustment guide rod 24 and the screw form a double-axis limit to prevent the single lens frame 1 from flipping or misaligning. When the ear distance adjustment is required, pinch the positioning hand-tightening column 51 and loosen it counterclockwise to drive the positioning screw 52 to rotate outward, so that the end of the screw is separated from the ear distance adjustment moving guide rail 41, releasing the fixation of the ear distance adjustment moving seat 4. At this time, the ear distance adjustment moving guide rail 41 can slide freely along the ear distance adjustment fixed guide rail 31.

[0016] This invention discloses an adjustable-width smart glasses system. Through an eye distance adjustment mechanism 2, the distance between two single lens frames 1 is precisely adjusted to accommodate the interpupillary distance of different users, ensuring accurate alignment of the lenses and pupils and avoiding optical deviations that could affect the viewing experience. Furthermore, by adjusting the relative sliding of the fixed and movable ear distance adjustment seats 3 and 6, the distance between the temples 6 is adjusted to accommodate the interauricular distance of different users, ensuring a close fit between the frames and the head. This solves the problem of traditional adjustable glasses failing to simultaneously meet the requirements for interpupillary and interauricular distance adaptation after adjustment, perfectly adapting to the wearing needs of adults, children, and other individuals with different head shapes within a family, significantly enhancing the versatility of smart glasses.

[0017] The dual-adjustment structure is easy to operate and has a firm positioning. After the ear distance is adjusted, the positioning mechanism 5 can effectively fix the position of the ear distance adjustment seat 4, preventing the smart glasses from automatically loosening or shifting due to shaking or squeezing during wear, ensuring the stability of wearing and convenient operation.

[0018] The elastic lens 7 automatically extends and retracts with the change in the spacing of the individual lens frames 1, effectively concealing the internal interpupillary distance adjustment mechanism 2 and resulting in a more aesthetically pleasing appearance. While adjusting the interpupillary distance, the effective length of the temples 6 is simultaneously adjusted, accommodating the needs of people with larger head shapes who require longer interpupillary distances. This solves the problem of temples pressing against the temples and causing discomfort caused by traditional methods that only adjust the left and right spacing of the temples, resulting in a better fit between the frame and the head and further improving wearing comfort for people with different head shapes.

[0019] By rotating the manual wheel to drive the screw, the threaded connection allows for precise micro-adjustment of the distance between individual lens frames 1. Compared to traditional snap-on adjustments, this method offers higher precision and a closer fit to the user's actual eye distance, ensuring accurate alignment between the lens and pupil. This prevents eye distance adjustment deviations from affecting the display and visual effects of the smart glasses. The threaded adjustment structure also boasts excellent self-locking properties, preventing eye distance shifts without additional positioning. The guide rod and adjustment screw work together to form a dual-axis limit, effectively preventing the two individual lens frames 1 from flipping or misaligning during adjustment. This ensures that each individual lens frame 1 remains horizontally aligned with the user's eyes, avoiding visual deviations and eye strain caused by lens angle shifts, thus improving the user experience and visual comfort of the smart glasses. The guide rail ensures smoother and more stable sliding of the ear distance adjustment seat 4, without jamming or shifting. This guarantees symmetrical spacing on both sides of the temples 6 after adjustment, resulting in even force distribution on the frame and a better fit to the head when worn. Simultaneously, the guide rail structure's limiting effect prevents excessive slippage during ear distance adjustment, thus improving the stability of the adjustment structure. No professional tools are required; the screw can be tightened or loosened by manually turning the column, quickly completing the positioning and readjustment after the ear distance adjustment, making it easy to operate. The positioning method of the screw pressing against the moving guide rail is firm and reliable, which can effectively resist the impact of external forces during wearing, completely preventing the temple 6 from loosening or shifting, ensuring the stability of wearing smart glasses. At the same time, the screw and screw hole have high precision, and long-term use will not easily cause problems such as stripping or positioning failure.

[0020] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
