Description

Technical Field

[0001] This utility model relates to a diopter adjustment structure, and more particularly to a diopter adjustment structure for smart glasses, belonging to the field of smart glasses technology. Background Technology

[0002] Smart glasses, also known as smart glasses, are like smartphones with their own operating system. Users can install software, games, and other programs provided by software service providers on smart glasses. However, when wearing smart glasses, the glasses interfere with each other, making it inconvenient to wear them. Therefore, a refractive adjustment mechanism needs to be added to smart glasses to adapt to the wearer's myopia.

[0003] The "Diopter Adjustment Device and Head-Mounted Display Device" disclosed in application number "202322930794.9" is also an increasingly mature technology, including a visual module and a driving mechanism. The visual module includes a tray, a fixed lens barrel with a fixed lens, an adjusting inner lens barrel with an adjusting lens, and an adjusting outer lens barrel. The fixed lens barrel is fixedly mounted on the tray. The adjusting inner lens barrel is axially movably fitted inside the fixed lens barrel, and a radially extending push column is provided on the adjusting inner lens barrel. The adjusting outer lens barrel is rotatably fitted outside the fixed lens barrel through a rotational guide structure, and a spiral guide groove is provided inside the adjusting outer lens barrel. When the driving mechanism drives the adjusting outer lens barrel to rotate, the adjusting inner lens barrel moves axially under the cooperation of the spiral guide groove and the push column, thereby changing the distance between the adjusting lens and the fixed lens to achieve diopter adjustment. This utility model relates to a refractive power adjustment device and a head-mounted display device, enabling refractive power adjustment and meeting the needs of users with different vision levels to share the same product. Further research revealed that application number "202311511211.7" discloses a "refractive power adjustment device and VR device," which includes a lens mounting section for mounting a lens module; a guide adjustment section connected to the lens mounting section, which can move along a preset path to cause the lens mounting section to move in a first direction; and a drive section for driving the guide adjustment section to move along the preset path. Compared with the prior art, this invention, by setting up a lens mounting section, a guide adjustment section, and a drive section, and by using the drive section to drive the guide adjustment section to move along the preset path, thereby causing the lens mounting section to reciprocate, achieves automatic refractive power adjustment.

[0004] However, the above method still has the following drawbacks in actual use: while adjusting the diopter, it is not possible to adjust the pupillary distance of the glasses in sync with the wearer's pupillary distance. Therefore, this utility model provides a smart glasses diopter adjustment structure. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4This utility model provides an intelligent eyeglasses diopter adjustment structure, including a housing 1. Two frames 2 are slidably connected to both sides inside the housing 1, and the two frames 2 move within the housing 1 to adapt to the wearer's interpupillary distance. Two fixing plates 7 are fixedly connected to both sides of the inner wall at the top of the housing 1. A bidirectional lead screw 8 is rotatably connected between the two fixing plates 7 via a bearing. A first movable seat 6, threadedly connected to the middle of the top of the frame 2, is fixedly connected to the two first movable seats 6. Under the threaded engagement of the bidirectional lead screw 8 and the two first movable seats 6, the two first movable seats 6 move synchronously, facilitating the adjustment of the position of the two frames 2. A fixed lens 4 is fixedly connected to one side inside the frame 2, facilitating subsequent diopter adjustment. A protective lens 3 is fixedly connected to the other side inside the frame 2. An adjusting lens 13 is slidably provided inside the frame 2, and its position is adjusted by an adjusting mechanism 5. The protective lens 3 protects the adjusting mechanism 5.

[0024] A first guide block 9 is fixedly connected to the middle of the top of the first movable seat 6. A first guide groove 10 is provided on both sides of the inner wall of the top of the housing 1 to slide with the first guide block 9. The first guide groove 10 limits the direction of movement of the first guide block 9, thereby limiting the direction of movement of the first movable seat 6.

[0025] A first motor 11 is fixedly installed on one side of the inner wall of the top of the housing 1. One end of the bidirectional lead screw 8 passes through one of the fixed plates 7 and is fixedly connected to the drive shaft of the first motor 11. When the first motor 11 is started, it provides power to the bidirectional lead screw 8, which can automatically adjust the distance between the two frames 2. A first button 12 is fixedly installed on one side of the front of the housing 1. The first motor 11 is electrically connected to the power supply inside the housing 1 through the first button 12. The first button 12 can control the switch of the first motor 11, thereby facilitating the adjustment of the interpupillary distance of the smart glasses.

[0026] Specifically, first, press the first button 12 to turn on the first motor 11, which drives the bidirectional lead screw 8 to rotate. With the threaded engagement between the bidirectional lead screw 8 and the two first moving seats 6, the two first moving seats 6 move linearly, causing the two eyeglass frames 2 to move towards each other simultaneously. This can increase or decrease the distance between the two eyeglass frames 2, and adjust the distance between the two eyeglass frames 2 according to the wearer's interpupillary distance to make the image clearer.

[0027] Example 2:

[0028] The adjustment mechanism 5 includes two second guide blocks 501 and two second guide grooves 502. The two second guide blocks 501 are fixedly connected to the middle of the top end and the middle of the bottom end of the adjustment lens 13, respectively. The two second guide grooves 502 are respectively opened in the middle of the inner wall of the top end and the middle of the inner wall of the bottom end of the frame 2. The second guide blocks 501 are slidably connected inside the second guide grooves 502. The second guide grooves 502 limit the direction of movement of the second guide blocks 501, thereby limiting the direction of movement of the adjustment lens 13, so that the adjustment lens 13 moves linearly and adjusts the diopter of the glasses.

[0029] A transmission groove 504 is provided in the middle of the inner wall of one side of the lens frame 2. A connecting screw 505 is rotatably connected to the inside of the transmission groove 504 through a bearing. A second movable seat 506 is slidably connected to the inside of the transmission groove 504 and threadedly connected to the connecting screw 505. One side of the second movable seat 506 is fixedly connected to the middle of one side of the adjusting lens 13. Under the threaded engagement between the connecting screw 505 and the second movable seat 506, the second movable seat 506 moves linearly, driving the adjusting lens 13 to move. Through the transmission between the connecting screw 505 and the second movable seat 506, it is convenient to change the distance between the adjusting lens 13 and the fixed lens 4.

[0030] A mounting groove 507 is provided in the middle of one side of the front of the lens frame 2. A second motor 508 is fixedly installed inside the mounting groove 507. One end of the connecting screw 505 extends into the interior of the mounting groove 507 and is fixedly connected to the drive shaft of the second motor 508. When the second motor 508 is started, it provides power to the connecting screw 505, which can automatically change the position of the adjusting lens 13, thereby adjusting the diopter. A cover plate 503 is fixedly installed on the front of the mounting groove 507 by screws. Unscrewing the screws opens the cover plate 503, which is convenient for regular maintenance of the second motor 508. A second button 509 is fixedly installed in the middle of one side of the front of the lens frame 2. The second motor 508 is electrically connected to the power supply in the housing 1 through the second button 509. The second button 509 can control the switch of the second motor 508, which is convenient for adjusting the distance between the fixed lens 4 and the adjusting lens 13.

[0031] Specifically, first, press the second button 509 to control the second motor 508 to turn on, causing the connecting screw 505 to rotate. With the threaded engagement between the connecting screw 505 and the second moving seat 506, the adjusting lens 13 moves back and forth, thereby changing the distance between the adjusting lens 13 and the fixed lens 4, which can adjust the refractive power of the smart glasses according to the wearer's myopia degree.

[0032] In use, first press the first button 12 to control the first motor 11 to turn on, which drives the bidirectional lead screw 8 to rotate. Under the threaded engagement of the bidirectional lead screw 8 and the two first moving seats 6, the two first moving seats 6 move linearly, causing the two frames 2 to move towards each other at the same time. This can increase or decrease the distance between the two frames 2. The distance between the two frames 2 can be adjusted according to the wearer's pupillary distance. While adjusting the diopter of the glasses, the pupillary distance can also be adjusted to make the picture clearer.

[0033] After putting on the smart glasses, pressing the second button 509 controls the second motor 508 to turn on, causing the connecting screw 505 to rotate. With the threaded engagement between the connecting screw 505 and the second moving seat 506, the second moving seat 506 moves linearly, driving the adjusting lens 13 to move back and forth, thereby changing the distance between the adjusting lens 13 and the fixed lens 4. This allows the refractive power of the smart glasses to be adjusted according to the wearer's myopia degree, making the smart glasses suitable for wearers with different myopia levels.
