Description

Technical Field

[0001] The present invention relates to the application field of AR glasses, and in particular to assembled AR glasses. Background Art

[0002] AR glasses are glasses with augmented reality technology that can superimpose virtual images on real scenes, allowing users to see a mixture of virtual images and the real world. Unlike VR glasses, AR does not completely replace reality but adds virtual elements to the real world to enhance users' perception and interactive experience. It can be used in various industries such as games, education, medical care, manufacturing, etc.

[0003] AR glasses mainly include nose pads, temples, protective covers and optical modules. The optical module is the main working component and contains two groups corresponding to the left and right eyes of a person. The miniature OLED display screen projects the image downward, and the image is enlarged and zoomed through the hemispherical diopter under the screen. The image is then reflected by the inclined semi-transparent and semi-reflective mirror close to the human eye. Finally, the light hits the spherical semi-transparent and semi-reflective mirror to flip the entire image 90°, and then the image is projected into the human eye through a polarization beam splitter.

[0004] With the development of AR glasses technology, the existing AR glasses can not only manually adjust the diopter, so that myopic users can also better use AR glasses, but the temples of AR glasses can be adjusted in multiple gears in the vertical direction to cope with some users whose eyes and ears are not at the same level. At the same time, AR glasses manufacturers generally provide users with three different sizes of nose pads, so that users can replace the corresponding nose pads according to the height of their nose bridge. This series of measures has improved the user experience of AR glasses. According to the feedback from some users after use, we learned that the optical module of AR glasses can be suitable for most users, but for some users with larger or smaller pupil distances, such as children, when using them, not only are the glasses easy to sag when worn, but it is also easy to cause the frame of the AR glasses to appear double in the picture, so that AR glasses cannot better meet user needs.

Example

[0032] An assembled AR glasses, such as Figure 1-20 As shown, a nose pad bracket 8 is movably installed inside the shell 701, and the nose pad bracket 8 includes an insertion rod 801, and a locking rack 802 is arranged on the side of the insertion rod 801, and the locking rack 802 is symmetrically arranged on both sides of the insertion rod 801, and two groups of memory metal support feet 804 are arranged at the bottom of the insertion rod 801, and an airbag nose pad 805 is installed at the end of the memory metal support foot 804. By setting the nose pad bracket 8 movably installed inside the shell 701, the nose pad bracket 8 can be adjusted in length to adapt to different users and improve the user experience of the AR glasses.

[0033] See also Fig. 9 , Fig.10 , Fig.13 and Fig.19 The shell 701 is provided with a nose pad adjustment mechanism 9 for adjusting the length of the nose pad bracket 8, and the nose pad adjustment mechanism 9 includes a face gear 901 installed outside the second fixing rod 707, and the face gear 901 is fitted with the first spring 709, and the nose pad adjustment mechanism 9 includes two sets of transmission gears 902 rotatably connected to the shell 701, and a third fixing rod 903 is provided at the bottom of one set of transmission gears 902, and a fourth fixing rod 904 is rotatably connected to the inside of the shell 701, and the fourth fixing rod 904 and the third fixing rod 903 are By setting a bevel gear assembly 905 for transmission connection, and a spur gear 906 is set at the end of the fourth fixed rod 904, and the spur gear 906 and the transmission rack 803 are meshed with each other, the nose pad adjustment mechanism 9 can be set to adjust the length of the nose pad bracket 8 inside the shell 701, and then the user can adjust the nose pad bracket 8 according to needs, so that the wearing of the AR glasses is more stable and comfortable. Compared with the prior art, the nose pad adjustment mechanism 9 can facilitate the user to adjust the length of the nose pad bracket 8 anytime and anywhere, and there is no need to use tools such as screwdrivers, which is convenient and quick.

[0034] See also Fig.10 , Fig.13 , Fig.15 , Fig.19 and Fig. 20The shell 701 is provided with a nose pad self-locking mechanism 10 for locking the nose pad bracket 8, and the nose pad self-locking mechanism 10 includes a U-shaped frame 1001 rotatably connected to the outside of the second fixed rod 707, and two groups of trapezoidal blocks 1002 are arranged at the bottom of the U-shaped frame 1001, the nose pad self-locking mechanism 10 includes two groups of linkage bar bars 1003 movably installed inside the shell 701, and the side of the linkage bar bar 1003 is provided with an arc groove 1006, the bottom of the linkage bar bar 1003 is provided with a metal rod 1004, and the metal rod 1004 is movably penetrated into the inside of the shell 701, and the outside of the metal rod 1004 is sleeved with a second spring 1005, and the nose pad self-locking mechanism 10 includes two groups of annular lock buckles 100 movably installed inside the shell 701 7, and the outer sleeve of the annular lock buckle 1007 is provided with two groups of third springs 1008, and the annular lock buckle 1007 matches the engaging rack 802, and the nose pad bracket 8 is provided with a nose pad self-locking mechanism 10 inside the shell 701, which can limit the nose pad bracket 8. If there is no nose pad self-locking mechanism 10, the nose pad bracket 8 will slide inside the shell 701 without limiting, so that the nose pad bracket 8 will shake during wearing, and the bevel gear assembly 905 in the nose pad adjustment mechanism 9 can also limit the nose pad bracket 8 by setting a one-way transmission component, for example: the bevel gear assembly 905 is replaced with a worm gear, and the second fixing rod 707 is rotated to drive the face gear 901 to rotate, and the face gear 901 is meshed with the transmission gear 902, so that the third fixing rod 707 is fixed. The rod 903 will drive the spur gear 906 to rotate through the worm gear, that is, the spur gear 906 can rotate to adjust the length of the nose pad bracket 8 when the second fixed rod 707 rotates. Conversely, the spur gear 906 can also limit the nose pad bracket 8 without rotating. However, this method will cause the user to accidentally let the nose pad bracket 8 slip out of the shell 701 or the manufacturer installs the nose pad bracket 8 into the shell 701 for the first time. The second fixed rod 707 needs to be pulled out to ensure that the face gear 901 and the transmission gear 902 are meshed, and then the second fixed rod 707 is rotated to drive the spur gear 906 to install the nose pad bracket 8 into the shell 701. Because the adjustment knob 10 has a small structure, the speed of rotating the second fixed rod 707 is slow, which makes the nose pad bracket 8 The length adjustment of the bracket 8 is also slow, and the nose pad self-locking mechanism 10 is different. When the nose pad adjustment mechanism 9 is working, the nose pad self-locking mechanism 10 can be automatically started when the second fixing rod 707 is pulled out, and the restriction on the nose pad bracket 8 is released. At this time, the bevel gear assembly 905 can be used to rotate between the third fixing rod 903 and the fourth fixing rod 904, and the length of the nose pad bracket 8 can be adjusted without rotating the second fixing rod 707. It can be directly inserted into the shell 701 by directly pressing. At this time, manually pressing the nose pad bracket 8 into the shell 701 will drive the second fixing rod 707 to drive in the reverse direction, which is more convenient for users to quickly make preliminary adjustments to the length of the nose pad bracket 8 and is also convenient for manufacturers to install for the first time. Then, the second fixing rod 707 is rotated to fine-tune the nose pad bracket 8.When the second fixing rod 707 is reset into the housing 701, the annular lock buckle 1007 limits the nose support bracket 8. Example

[0035] An assembled AR glasses, such as Figure 1-20 As shown, the housing 701 is provided with a knob locking mechanism 11 for locking the second fixing rod 707, and the knob locking mechanism 11 includes an outer convex ring 1101 rotatably connected to the outside of the second fixing rod 707, and a one-way threaded rod 1102 is provided on the side of the outer convex ring 1101, and the outer thread of the one-way threaded rod 1102 is connected to an adjusting sleeve 1103, the knob locking mechanism 11 includes a strip groove 1104 opened on the side of the housing 701, and the strip groove 1104 matches the one-way threaded rod 1102, and the knob locking mechanism 11 includes a circular groove 1104 opened on the side of the housing 701 105, and the circular groove 1105 and the adjusting sleeve 1103 match each other. By setting the knob locking mechanism 11, the second fixing rod 707 can be locked, so that the second fixing rod 707 is more stable when acting on the nose pad adjusting mechanism 9, and it is convenient for the user to turn the adjusting knob 710. If there is no knob locking mechanism 11, the user needs to pull out the adjusting knob 710 all the time to make the first spring contract and the face gear 901 and the transmission gear 902 engage to ensure that the nose pad adjusting mechanism 9 works. The knob locking mechanism 11 can ensure that the second fixing rod 707 will not be actively reset after being pulled out.

[0036] The working principle of the present invention is as follows: when the glasses module 3 of the AR glasses needs to be adjusted, the user rotates the adjustment knob 710 to drive the second fixed rod 707 to rotate. Under the reset action of the first spring 709, the locking clutch assembly 708 is closed, and the second fixed rod 707 drives the first fixed rod 705 to rotate. The first fixed rod 705 drives the positive and negative threaded rod 702 to rotate through the worm gear assembly 706. By utilizing the screw principle, the two groups of threaded sleeves 704 threadedly connected to the outside of the positive and negative threaded rods 702 are moved away from or close to each other, that is, the distance between the two groups of glasses modules 3 is adjusted. The two groups of glasses modules 3 will slide on the slide rail 2 to adjust the spacing, and the bar limit block 703 will limit the threaded sleeve 704 when it moves.

[0037] When the user needs to adjust the nose pad bracket 8, the user first pulls the adjusting knob 710, and the adjusting knob 710 drives the second fixing rod 707 to move, and then the second fixing rod 707 drives the face gear 901 to move. During the movement of the face gear 901, the first spring 709 will be compressed, the locking clutch assembly 708 will open, and the face gear 901 will engage with the two sets of transmission gears 902. The movement of the second fixing rod 707 will also drive the outer convex ring 1101 to move, and the outer convex ring 1101 drives the one-way threaded rod 1102 to slide in the strip groove 1104, and then keep the adjusting knob 710 still in the pulling state, rotate the adjusting sleeve 1103, so that the adjusting sleeve 1103 is engaged in the circular groove 1105, and under the limiting action of the adjusting sleeve 1103 and the circular groove 1105, the second fixing rod 707 will always remain in the pulled out state.

[0038] Similarly, the second fixing rod 707 will drive the U-shaped frame 1001 to move, and then the trapezoidal block 1002 at the bottom of the outer convex ring 1101 will squeeze the linkage bar 1003, so that the height of the linkage bar 1003 will drop, and the linkage bar 1003 will compress the second spring 1005, and use the arc groove 1006 to squeeze the annular lock buckle 1007, so that the annular lock buckle 1007 will squeeze the third spring 1008, that is, the two groups of annular lock buckles 1007 are retracted into the interior of the shell 701, releasing the restriction of the annular lock buckle 1007 on the side engagement rack 802 of the nose pad bracket 8, and then the user turns the adjustment knob 710 to drive the second fixing rod 707 to rotate, at this time the face gear 901 and the two groups of transmission gears 902 are meshed with each other, and the two groups of transmission gears 902 are set to make the face gear 901 rotate more stably, and the rotation of one group of transmission gears 902 will drive the third fixing rod 903 to rotate, and the third fixing rod 903 drives the third fixing rod 903 to rotate through the bevel gear assembly 905. The fourth fixing rod 904 rotates, and the fourth fixing rod 904 drives the spur gear 906 to rotate, and then the spur gear 906 rotates and engages with the transmission rack 803 on the side of the nose pad bracket 8, so that the spur gear 906 rotates to adjust the length of the nose pad bracket 8 inside the shell 701. When the length of the nose pad bracket 8 is adjusted, the user loosens the adjustment sleeve 1103, and the limiting effect of the adjustment sleeve 1103 and the circular groove 1105 is lost. The second fixing rod 707 retracts into the interior of the shell 701 under the reset action of the first spring 709, the outer convex ring 1101 is reset, the locking clutch assembly 708 is closed again and the U-shaped frame 1001 is reset, so that the linkage strip rod 1003 rises under the reset action of the second spring 1005, and then the annular lock buckle 1007 is engaged with the engaging rack 802 on the side of the nose pad bracket 8 under the reset action of the third spring 1008, that is, the annular lock buckle 1007 locks the nose pad bracket 8 to prevent it from loosening and sliding out.
