Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and in particular to AR / MR smart glasses. Background Art

[0002] At present, wearable devices are mainly developed in the mainstream direction of VR, AR and MR technologies. It is known that VR smart glasses are virtual reality smart glasses, AR smart glasses are virtual augmented reality smart glasses, and MR smart glasses are virtual mixed reality smart glasses. However, for existing AR, VR or MR smart glasses, the distance between the centers of the two lenses (optical center) is fixed. Since everyone's pupil distance is different, if the distance between the centers of the two lenses (optical center) does not match the user's pupil distance, the user will feel very strenuous and uncomfortable when using it. The greater the degree of correction, the more uncomfortable it is, which will eventually affect the person's vision.

[0003] For example 1: The Chinese invention patent with application publication date of January 25, 2019 and application publication number CN109270694A discloses a smart glasses capable of realizing AR, VR or MR, including a frame with lenses mounted thereon, temples connecting the two sides of the frame, a semi-transparent and semi-reflective film attached to the lenses, a display disposed on the inner side of the lenses to reflect the displayed content in front of the eyes of the human eye through the semi-transparent and semi-reflective film, and a light valve disposed on the outer side of the lenses to selectively block the visual angle of the human eye in coordination with the displayed content. Therefore, it is still impossible to adjust the distance between the centers of the two lenses (optical center), and thus it is impossible to adjust according to the actual situation to meet people's actual needs.

[0004] Example 2: The Chinese invention patent with the authorization announcement date of March 27, 2018 and the authorization announcement number CN207148426U discloses a VR glasses with increased pupil distance adjustment distance, which relates to the field of electronic product technology, including two symmetrically arranged lens assemblies, on which an adjustment assembly for adjusting the distance between the two lens assemblies is installed; connectors are arranged at two symmetrical positions with the smallest distance between the two lens assemblies, and the connectors include a first card block and a second card block that are snap-fitted. Although the range of pupil distance adjustment has been increased, there are many such parts for the adjustment assembly, which makes the parts more complicated and greatly increases the weight of the glasses, making the users uncomfortable to wear, and thus failing to meet the needs of the users. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0039] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0040] See also Figure 1 As shown in the figure, an AR / MR smart glasses has a frame 1 in the shape of a frame, which has the same appearance and shape as ordinary glasses or sunglasses. Both sides of the frame 1 are hinged or fixedly connected with temples 2. The frame 1 is provided with lenses 3. The frame 1 includes a first frame 11 and a second frame 12. The lenses 3 include a first eyeglass lens 31 and a second eyeglass lens 32. The first eyeglass lens 31 is installed on the first frame 11, and the second eyeglass lens 32 is installed on the second frame 12. A distance adjustment mechanism 4 for adjusting the center distance between the first eyeglass lens 31 and the second eyeglass lens 32 is provided between the first frame 11 and the second frame 12. The distance between the first frame 11 and the second frame 12 is carefully adjusted by the distance adjustment mechanism 4 to adjust the center distance between the first eyeglass lens 31 and the second eyeglass lens 32, so as to better match the different pupil distances of each user. Specifically, as Figure 2 As shown, in the embodiment of the present invention, a positioning column 111 is provided on the first frame 11, and a positioning groove 121 is provided on the second frame 12. The positioning column 111 moves back and forth in the positioning groove 121, thereby playing a role in positioning the first frame 11 and the second frame 12, and also playing a role in connecting.

[0041] Further, if Figure 2As shown, the distance adjustment mechanism 4 includes a track groove 41 arranged on the first frame 11, and locking holes 42 are evenly distributed on the track groove 41. Correspondingly, a track 43 is arranged on the second frame 12, and matching holes 44 are evenly distributed on the track 43. The track 43 moves back and forth on the track groove 41, and when the locking holes 42 on the track 43 and the matching holes 44 on the track groove 41 coincide with each other, a fixing member 45 and a locking member can be installed on the corresponding locking holes 42 and matching holes 44 at this time, so that the track 43 can be fixedly connected to the track groove 41, and finally the first frame 11 and the second frame 12 are fixed. The fixing member 45 is located at the nose position, and the locking member is located on the side of the fixing member 45, preferably two locking members, and the two locking members are preferably distributed on both sides of the fixing member 45 (one on each side), which is more conducive to fixing and locking the first frame 11 and the second frame 12, and the bolts used in the locking members are conventional technology for bolts, so they are not described one by one. With this arrangement of the present invention, during use, the track 43 on the second frame 12 can be moved back and forth in the track groove 41 on the first frame 11 by hand, thereby adjusting the distance between the second frame 12 and the first frame 11, which is conducive to adjusting the center distance between the first lens 31 and the second lens 32, so as to better match the different pupil distances of each user. Finally, when the corresponding locking holes 42 and matching holes 44 coincide with each other, the track 43 and the track groove 41 are fixedly connected together by the fixing member 44, and finally the first frame 11 and the second frame 12 are fixed. On the one hand, this type of parts is less and easy to produce. On the other hand, its track 43 and track groove 41 will not occupy the area of ​​the first frame 11 and the second frame 12 separately. At the same time, the volume is relatively light, which is conducive to the bulky structure commonly used in the prior art, thereby making it more convenient for users to wear.

[0042] Furthermore, if Figure 2As shown, the track groove 41 includes a mounting seat 411 arranged on the upper end surface of the first mirror frame 11, and a transverse mounting groove 412 is arranged on the mounting seat 411. The transverse mounting groove 412 can be used to install the track 43. The track 43 can move back and forth in the transverse mounting groove 412, and locking holes 42 are evenly spaced on the mounting seat 411. The locking holes 42 vertically penetrate the mounting seat 411, which is more conducive to the later fixing part 45 to lock the track 43 and the track groove 41. The track 43 includes a transverse guide body 431 arranged on the upper end surface of the second frame 12, and the transverse guide body 431 is evenly spaced with matching holes 44. The transverse guide body 431 moves back and forth in the transverse mounting groove 412. When the corresponding locking holes 42 and matching holes 44 coincide with each other, the track 43 is fixedly connected to the track groove 41 through the fixing member 45, and finally the first frame 11 and the second frame 12 are fixed. This setting has a simple structure, and it is located on the upper end surface of the first frame 11 and the second frame 12. Moreover, this track 43 is not exposed to the outside, but hidden in the transverse mounting groove 412 of the mounting seat 411, which greatly improves the novelty when worn by the user, is more beautiful, and better meets the user's use needs. At the same time, it is also conducive to the user's manual adjustment, which greatly facilitates everyone's user.

[0043] In any of the above embodiments, Figure 2 and Figure 3 As shown, the fixing member 45 includes a lower rod 451 and an upper nose pad 452 extending toward the upper part of the nose bridge. The lower rod 451 and the upper nose pad 452 are integrally formed, and the lower rod 451 passes through the locking hole 42 and the matching hole 44. The lower rod 451 is threaded. In this case, the fixing member 45 only needs to be manually rotated clockwise so that the lower rod 451 enters the corresponding locking hole 42 and the matching hole 44, and the locking state is achieved. The fixing member 45 is rotated counterclockwise so that the lower rod 451 is disengaged from the corresponding locking hole 42 and the matching hole 44, and the loose state is achieved. The fixing member 45 of this arrangement can realize the fixing of the first frame 11 and the second frame 12 after adjustment, and on the other hand, the upper nose pad 452 can be in the position of the upper nose pad 452 when looking close, and it is consistent with the corner of the eye of the face, so as to achieve the purpose of comfortable wearing.

[0044] In any of the above embodiments, Figure 4As shown, it is more important to emphasize that an upper rack 46 is provided on the inner wall of the transverse mounting groove 412 in the mounting seat 411, and correspondingly, an upper protrusion 47 is provided on the upper end surface of the transverse guide rail body 431, and the upper rack 46 cooperates with the upper protrusion 47. During use, the upper rack 46 and the upper protrusion 47 realize the positioning and locking of the left and right back and forth movement, and have the purpose of gear adjustment, which can achieve the purpose of adjusting the pupil distance, which is conducive to adjusting according to the different pupil distances of each person, and at the same time, its left and right movement can generate vibration, which makes it easier for the user to master the adjustment of the distance adjustment mechanism 4, so that the pupil distance suitable for the user's needs can be adjusted.

[0045] Further, in any of the above embodiments, if Figure 5 and Figure 6 As shown, the first eyeglass 31 and the second eyeglass 32 both include a plano-convex mirror 310 and a plano-concave mirror 320, and the convex surface of the plano-convex mirror 310 is arranged opposite to the concave surface of the plano-concave mirror 320, so that the first eyeglass 31 and the second eyeglass 32 can both magnify the displayed content, and a semi-transparent and semi-reflective film 330 is arranged between the convex surface of the plano-convex mirror 310 and the concave surface of the plano-concave mirror 320, so that the semi-transparent and semi-reflective film 330 also has a certain magnification effect when reflecting. It should be pointed out that the plano-concave mirror 320, the plano-convex mirror 310 and the semi-transparent and semi-reflective film 330 of the present invention are closely attached to each other, and the whole forms a lens with a semi-transparent and semi-reflective effect. In order to adapt to users with different vision abilities, the plano-convex mirror 310 and the plano-concave mirror 320 can adjust their convex and concave surfaces to form a plano-lens with a degree of 0, or the plano-convex mirror 310 and the plano-concave mirror 320 can be combined to form a myopia lens with a negative degree, or the plano-convex mirror 310 and the plano-concave mirror 320 can be combined to form a hyperopia lens with a positive degree.

[0046] Furthermore, based on any of the above embodiments, Figure 7 As shown, a display 5 is provided on the inner side of the lens 3, and a light valve 6 is provided on the outer side of the lens 3. Specifically, a display 5 is provided on the inner side of the first lens 31 and the second lens 32, and a light valve 6 is provided on the outer side of the first lens 31 and the second lens 32. In this way, the display content of the display 5 facing the lens 3 is in front of the human eye, and the light valve 6 can selectively block the human eye's field of view according to the display content. When the AR function is implemented, the light valve 6 selectively blocks the virtual characters, objects, icons, etc. displayed on the display 5, so that the virtual scenery of the smart glasses is not translucent, but completely opaque and can block the physical scene to present a sense of reality. For example, the light valve 6 can select a grayscale adjustable black and white LCD display with a higher resolution, and can selectively block the field of view, and only block the virtual part to achieve the most realistic mixed reality effect. The entire light valve 6 is black, and the user will only see the virtual image displayed by the display 5. At this time, the VR function can be realized. Among them, as Figure 7As shown, the display 5 includes a first display block 51 and a second display block 52, and the first display block 51 and the second display block 52 are installed on the corresponding first frame 11 and the second frame 12, and the first frame 11 and the second frame 12 are provided with corresponding first display block mounting grooves and second display block mounting grooves, so that the first display block mounting grooves and the second display block mounting grooves on the first frame 11 are correspondingly installed with the first display block 51 and the second display block 52, and the first display block mounting grooves and the second display block mounting grooves on the second frame 12 are correspondingly installed with the first display block 51 and the second display block 52. In this way, a display 5 can be formed by the first display block 51 and the second display block 52, which greatly reduces the difficulty of installation and also reduces the number of display blocks. This number is more suitable and convenient for installation. In the embodiment, the first display block 51 is the upper display block, and the second display block 52 is the lower display block. The upper display block and the lower display block are combined into a corresponding display 5 in the corresponding first frame 11 and second frame 12. In the present invention, a display 5 is formed by the first display block 51 and the second display block 52. During use, the display 5 is arranged on the upper and lower sides of the eyes of the person without blocking the line of sight. At the same time, the positional relationship between the display 5 and the corresponding first eyeglass lens 31 and the second eyeglass lens 32 is adjusted so that the first display block 51 and the second display block 52 of the same first eyeglass lens 31 display content and the enlarged virtual image formed after the first eyeglass lens 31 are seamlessly spliced ​​together, and the first display block 51 and the second display block 52 of the same second eyeglass lens 32 display content and the enlarged virtual image formed after the second eyeglass lens 32 are seamlessly spliced ​​together, so that both eyes can see. In this way, when implementing AR, VR or MR functions, especially when implementing AR functions, full viewing angles of the eyes in all directions can be achieved. However, when existing products implement AR functions, the virtual image projected by the display 5 only occupies a fixed part, so the full viewing angle of the eyes in all directions cannot be achieved.

[0047] In any of the above embodiments, if Figure 8 and Fig. 9As shown, it also includes a computing device 7 connected to the temple 2. The computing device 7 includes a housing 71. A processor 72, a memory 73, a first interface 74 and a power supply 75 are arranged in the housing 71. The power supply 75 provides power to the processor 72, the memory 73 and the first interface 74. The computing device 7 is arranged separately, and the computing device 7 is arranged to be a device that can be worn on the shoulders of the user. When the user uses it, most of the weight is borne by the shoulders, so that it can be worn for a long time, and the computing device 7 is worn on the shoulders without special carrying. Further, the computing device 7 is arc-shaped, and this arc-shaped computing device 7 is used to be worn on the shoulders of the user. The housing 71 is an annular structure with an opening, and the housing 71 can be put on the shoulder or taken off the shoulder through the opening. What I want to explain more is that a second interface is arranged on the temple 2, and the second interface is arranged at the end of the temple. The second interface is connected to the first interface 74 through a wire. This device is more convenient for users to use.

[0048] In any of the above embodiments, if Fig.10 As shown, it also includes a falling prevention mechanism 8 ( Figure 8 The anti-drop mechanism 8 of the other end of the temple 2 is blocked and cannot be shown). The anti-drop mechanism 8 includes an arc block 81 arranged at the lower part of the rear end of the temple 2. The arc block 81 is made of rubber material. Because of its elasticity, it can fit the ears of different users. This is more conducive to contact with the ears during use. In this way, it can prevent falling to a certain extent during wearing, which is more conducive to the user's wearing.

[0049] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The display block, display, processor, memory, first interface, second interface and power supply internal components all adopt conventional models in the prior art, and their internal structures belong to the prior art structure. Workers can complete normal operation of them according to the existing technical manual. In addition, the circuit connection adopts the conventional connection method in the prior art, and no specific description is given here.

[0050] It should be noted that, although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
