Description

Technical Field

[0001] The present invention relates to the field of AR glasses technology, and more specifically, to an AR connection device. In addition, it also relates to an AR glasses device including the above-mentioned AR connection device. In addition, it also relates to an AR glasses assembly method applied to the above-mentioned AR glasses device. Background Art

[0002] At present, AR glasses generally fix the waveguide on the frame and the optical engine inside the temples. The glasses frame will be restricted by the optical engine and the waveguide. At the same time, the waveguide and the optical engine will also be affected by the glasses frame. That is to say, damage to any one of the components will affect the normal use of other components, so that the AR glasses need to be replaced as a whole, and cannot be repaired or replaced individually.

[0003] Moreover, since the waveguide and optical machine require extremely high assembly precision, the glasses frame also requires high assembly precision, which ultimately leads to problems such as AR glasses being difficult to process and assemble, high cost, difficult to replace, and having a single shape.

[0004] In the prior art, the assembly process of traditional AR glasses is as follows: Figure 1 As shown, first, the waveguide plate 6 is assembled into the waveguide plate limiting structure 01 in sequence; then, the prism 7 is assembled into the prism limiting structure 03 in sequence; then, the optical machine 8 is assembled into the optical machine limiting structure 04 in sequence; finally, the SLAM camera 9 is assembled into the SLAM camera limiting structure 02 in sequence. After all the components are assembled, AB glue is applied to the contact edge between the component and the limiting structure for reinforcement and fixation, and then the AR glasses appearance parts are covered, and the appearance parts are fixed by screws 18, and finally, the AR glasses temples 17 are installed.

[0005] Existing appearance parts are generally frames in the shape of glasses, and all of the above-mentioned limiting structures are set on the appearance parts. They are component structures of the appearance parts and are processed together with the appearance parts. Therefore, once the appearance needs to be changed or other adjustments need to be made, it will be very difficult and redesign and processing are required, which can easily lead to problems such as time-consuming, labor-intensive and costly.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The core of the present invention is to provide an AR connection device, which can effectively solve the problems of AR glasses being difficult to assemble, difficult to process, high cost, difficult to repair, and difficult to change the shape of appearance parts. It can make AR glasses easy to replace and design appearance parts of different shapes, so as to achieve the purpose of making the appearance of AR glasses more diverse and personalized.

[0046] Another core of the present invention is to provide an AR glasses device including the above-mentioned AR connecting device, which is easy to assemble and maintain, and easy to replace appearance parts of different shapes.

[0047] In addition, another core of the present invention is to provide an AR glasses assembly method applied to the above-mentioned AR glasses device, which is simple to operate and can be promoted for use.

[0048] Please refer to Figures 1 to 12 .

[0049] An AR connecting device provided in this specific embodiment is applied to AR glasses and is used to connect the core parts of the AR glasses. The AR connecting device includes: a limiting beam 5 for limiting the position of a waveguide plate 6, a waveguide plate bracket 1 for mounting the waveguide plate 6 and arranged below the limiting beam 5, and an optical machine bracket 4 for mounting an optical machine 8 and respectively arranged on the left and right sides of the limiting beam 5. The waveguide plate bracket 1 is connected to the optical machine bracket 4. The waveguide plate bracket 1 is provided with a light outlet 3 for propagating virtual light generated by the optical machine 8 to the waveguide plate 6. Mounting holes 2 for assembly with appearance parts are provided in the middle of the limiting beam 5 and on the optical machine bracket 4.

[0050] It should be noted that the AR connection device can be manufactured in one piece by means of, but not limited to, investment casting. Since the AR connection device is used to connect various core parts, it needs to have high dimensional accuracy and surface finish. In addition, the wall thickness of the entire structural part of the AR connection device ranges from 0.20mm to 2.00mm to avoid it being too heavy and causing a poor feel during use. Therefore, the AR connection device needs to have the advantages of being light, rigid, strong, and precise.

[0051] The present invention assembles a variety of optical parts on an AR connecting device to form a whole, thereby effectively improving the assembly accuracy of AR glasses and providing convenience for subsequent assembly, maintenance, replacement and other operations.

[0052] In actual application, the structure, shape, size, material, position, etc. of the AR connecting device can be determined according to actual conditions and actual needs.

[0053] It should also be noted that when assembling AR glasses using the AR connection device provided by the present invention, first, fix the waveguide plate 6 on the waveguide plate bracket 1, and then limit the position of the upper edge of the waveguide plate 6 by the limiting beam 5 above the waveguide plate bracket 1. After the position of the waveguide plate 6 is determined, apply metal AB glue to the edge where the waveguide plate bracket 1 contacts the waveguide plate 6 to strengthen fixation. Then, fix the optical machine 8 in the optical machine bracket 4. After the position of the optical machine 8 is determined, apply metal AB glue to the edge where the optical machine 8 contacts the optical machine bracket 4 to strengthen fixation. Finally, align the appearance part with the mounting hole 2 on the AR connection device, and insert the fixing part into the mounting hole 2 to fix the two together, thereby completing the overall assembly of the AR glasses.

[0054] By using the AR connecting device provided by the present invention, the complexity of the design and processing of the appearance parts of AR glasses can be effectively reduced, because the device connects and assembles all the core parts of the AR glasses on the AR connecting device, so that each core part becomes a module, and then is assembled and used with the appearance parts. In this way, the core parts will not affect the appearance parts, and the problems of AR glasses being difficult to assemble, difficult to process, high cost, difficult to repair, and difficult to change the shape of appearance parts can be effectively solved. AR glasses can be easily replaced and designed with appearance parts of different shapes, so as to achieve the purpose of making the appearance of AR glasses more diverse and personalized.

[0055] In summary, the AR connection device provided by the present invention can effectively solve the problems of AR glasses being difficult to assemble, difficult to process, high cost, difficult to repair, and difficult to change the shape of appearance parts. In addition, the device can make AR glasses easy to replace and design appearance parts of different shapes, so as to achieve the purpose of making the appearance of AR glasses more diverse and personalized.

[0056] On the basis of the above-mentioned AR connection device, preferably, the limiting beam 5, the waveguide plate bracket 1 and the optical machine bracket 4 are an integrated structure.

[0057] It should be noted that the AR connection device is set as an integrated structure to facilitate the overall assembly operation of the AR connection device, so as to improve the assembly efficiency and shorten the assembly time. The AR connection device can be made by injection molding, or by other materials such as metal precision casting and integrated molding.

[0058] It should also be noted that, in addition to manufacturing the AR connection device by one-piece molding, it is also possible to use local screws 18 to fix or weld to obtain an AR connection device with a similar positional relationship.

[0059] In addition, it should be noted that the AR connection device can be made of metal materials, or can be made of strong plastic or other composite materials. In actual use, the structure, material, position, size, connection process, etc. of the limit beam 5, the waveguide bracket 1 and the optical machine bracket 4 can be determined according to actual conditions and actual needs.

[0060] Preferably, the limiting beam 5 is an open limiting beam, and a bent edge is provided on the top of the limiting beam 5 for abutting against the upper edge of the waveguide plate 6 to limit the position of the waveguide plate 6 .

[0061] Preferably, the open-type limited crossbeam can be configured to be similar to a structure having only the upper frame of the glasses.

[0062] In the present embodiment, since the limiting beam 5 of the AR connecting device has only a top provided with a bent edge for abutting against the upper edge of the waveguide plate 6 to perform open-type limiting on the waveguide plate 6, the limiting beam 5 can be adapted to and replaced with waveguide plates 6 of various shapes, wherein the shape of the waveguide plate 6 can be circular, square, polygonal, elliptical, special-shaped, etc., that is, the shape of the waveguide plate 6 can be flexibly selected, which provides great convenience for the subsequent appearance design.

[0063] In actual use, the structure, shape, and size of the limiting beam 5 and the shape and size of the waveguide plate 6 can be set accordingly according to actual conditions and actual needs.

[0064] Preferably, the limiting beam 5 is a closed limiting, fully enclosing beam to improve the installation accuracy of the waveguide plate 6 .

[0065] It should be noted that the fully enclosed crossbeam may refer to a crossbeam that is set to a structure similar to the frame of glasses, so as to enclose the lens in the frame and effectively fix the position of the lens.

[0066] In addition, it should be noted that setting the limiting beam 5 as a closed limiting beam 5 can improve the fixing effect and installation accuracy of the waveguide sheet 6, and avoid the phenomenon that the waveguide sheet 6 is detached and damaged due to loosening of the connection and fixing part during use. The limiting beam 5 can be set as a fully enclosed beam, that is, the limiting beam 5 can be limited along the circumference of the waveguide sheet 6. The shape of the limiting beam 5 is similar to the frame structure, and a groove matching the shape and size of the waveguide sheet 6 is provided to clamp and fix the waveguide sheet 6.

[0067] It should be supplemented that the fully enclosed cross beam can be arranged higher than the installation plane of the waveguide plate 6 to facilitate the subsequent installation and fixing operation of the waveguide plate 6.

[0068] In actual use, the limiting method and structure, shape, size, etc. of the limiting beam 5 can be determined according to actual conditions and actual needs.

[0069] Preferably, a mounting position for mounting the prism 7 is provided at the connection between the waveguide support 1 and the optical machine support 4 .

[0070] It should be noted that, by providing a mounting position at the connection, it will be convenient for the user to install the prism 7 according to actual needs during the later use, so as to improve the use effect of the AR glasses. In the actual use process, the structure, size, shape, position, etc. of the mounting position can be determined according to the actual situation and actual needs.

[0071] Preferably, the optical machine bracket 4 is a U-shaped groove structure for clamping and fixing the optical machine 8 and matching the size of the optical machine 8 , and the optical machine 8 is provided with optical machine holes 13 corresponding one-to-one with the mounting holes 2 on the optical machine bracket 4 .

[0072] It should be noted that the optical machine bracket 4 is set as a U-shaped groove structure in order to better fix the optical machine 8. In addition, the optical machine 8 is provided with an optical machine hole 13 corresponding to the mounting hole 2 of the optical machine bracket 4, so that after the optical machine 8 is installed on the optical machine bracket 4, when the AR connection device is assembled with the appearance part, the appearance part should also be provided with a fixing hole 20 corresponding to the mounting hole 2, and then, after aligning the holes set one by one, the fixing parts are inserted into the holes to effectively fix the optical machine 8 and each device, thereby improving the overall assembly effect of the AR glasses.

[0073] Preferably, after the holes that are arranged one by one are aligned, screws 18 or other cylindrical structures can be passed through the holes to fix them.

[0074] In actual use, the structure, shape, size, material of the optical machine bracket 4 and the size, position, number, shape, etc. of the optical machine hole 13 and the mounting hole 2 can be determined according to actual conditions and actual needs.

[0075] On the basis of the above-mentioned AR connecting device, preferably, a SLAM camera bracket 10 for installing the SLAM camera 9 is provided on the limiting beam 5, and the SLAM camera bracket 10 is a closed limiting bracket to ensure the installation accuracy of the camera, and a camera bracket 12 for installing the camera 11 is provided on the waveguide bracket 1, and the camera bracket 12 is a closed limiting bracket to ensure the installation accuracy of the camera.

[0076] It should be noted that by adding a SLAM camera bracket 10 to the waveguide bracket 1 and adding a camera bracket 12 to the mounting plane of the waveguide bracket 1, the SLAM camera 9 and the camera 11 can be simultaneously assembled on the corresponding brackets to enrich the functionality of the AR connection device.

[0077] It should be further explained that the AR connection device without the SLAM camera bracket 10 and the camera bracket 12 can be called a basic AR connection device, and the AR connection device with the SLAM camera bracket 10 and the camera bracket 12 can be called an upgraded AR connection device. In addition, the SLAM camera bracket 10 and the camera bracket 12 are both configured as closed limit brackets to ensure the installation accuracy of each camera to avoid the phenomenon that the optical imaging quality is affected by the shaking of the camera.

[0078] Preferably, two SLAM camera brackets 10 may be symmetrically arranged above the waveguide bracket 1, and a camera bracket 12 may be arranged in the installation plane of the waveguide bracket 1. Of course, the SLAM camera bracket 10 may also be arranged below or on both sides of the waveguide bracket 1. That is, in actual use, the structure, size, shape, position, number, etc. of the SLAM camera bracket 10 and the camera bracket 12 may be determined according to actual conditions and actual needs.

[0079] It should be further explained that, according to the functional requirements of the AR glasses, an additional sensor bracket can be provided on the AR connecting device. The sensor bracket is used to effectively fix the sensor. The sensor may include a distance sensor, an ambient light sensor, a heart rate sensor, a body temperature sensor, a depth camera, etc., thereby further enriching the functions of the AR glasses.

[0080] In addition to the above-mentioned AR connecting device, the present invention also provides an AR glasses device including the above-mentioned AR connecting device, and the AR glasses device includes: a waveguide plate 6, an optical machine 8, an AR connecting device for connecting core parts, and an appearance part for assembly with the AR connecting device.

[0081] Preferably, the appearance part includes a first appearance part 15 for assembly with the outer side of the AR connecting device and a second appearance part 16 for assembly with the inner side of the AR connecting device. The first appearance part 15 and the second appearance part 16 are both provided with fixing holes 20 corresponding one-to-one to the mounting holes 2 of the AR connecting device. The fixing holes 20 are used to insert the fixing parts so that the appearance part and the AR connecting device form a closed state after assembly.

[0082] It should be noted that after the various optical core parts of the AR glasses are assembled on the AR connecting device, the first appearance component 15 is assembled with the outer side of the AR connecting device, and then the second appearance component 16 is assembled with the inner side of the AR connecting device. Since the three are provided with holes in a one-to-one correspondence, after each mounting hole 2 and the fixing hole 20 are aligned, the fixing component is inserted into the hole to achieve the overall fixed assembly of the AR glasses device.

[0083] In actual use, the shape, size, position, number, etc. of the fixing holes 20 can be determined according to actual conditions and actual needs to ensure the aesthetics of the exterior component.

[0084] In this embodiment, since the overall shape of the AR connection device is U-shaped, the portion inside the U-shape can be divided into the inner side, and the portion outside the U-shape can be divided into the outer side.

[0085] It should be noted that the shape and size of the first appearance part 15 and the second appearance part 16 should be compatible with the structure and size of the AR connecting device, so that after the appearance parts and the AR connecting device are assembled, a closed AR glasses device can be formed to effectively fix and protect the core parts of the AR glasses device, thereby improving the use effect of the AR glasses device.

[0086] During actual use, the structure, size, shape, material, etc. of the first appearance member 15 and the second appearance member 16 may be determined according to actual conditions and actual needs.

[0087] In addition, it should be explained that the first appearance member 15 and the second appearance member 16 mentioned in the present application document are only used to distinguish the difference in position, and there is no order of precedence.

[0088] In addition to the above-mentioned AR glasses device, the present invention also provides an AR glasses assembly method applied to any of the above-mentioned AR glasses devices, and the AR glasses assembly method comprises:

[0089] S1, fix the waveguide plate 6 on the waveguide plate bracket 1, and then limit the position of the waveguide plate 6 by the limiting beam 5.

[0091] S3, aligning the appearance component with the mounting hole 2 of the AR connecting device, and then inserting the fixing component into the mounting hole 2, so that the appearance component and the AR connecting device are fixedly connected.

[0092] It should be noted that a mounting position for installing the prism 7 can be set at the limiting beam 5 and the waveguide support 1. Then, in actual use, the prism 7 can be directly assembled in the reserved mounting position when assembling parts according to actual needs.

[0093] In order to better illustrate the AR connection device, AR glasses device and AR glasses device assembly method provided by the present invention, an example will be given below. The assembly process of the AR glasses device can be referred to Figure 2 .

[0096] Then, fix the optical machine 8 in the optical machine bracket 4. The optical machine bracket 4 can perform preliminary limit fixation on the optical machine 8, and align the optical machine holes 13 on the optical machine 8 with the mounting holes 2 on the optical machine bracket 4 one by one. Then, apply metal AB glue on the edge where the optical machine 8 contacts the optical machine bracket 4 for enhanced fixation.

[0097] Finally, the prism 7 is assembled in the mounting position reserved between the waveguide support 1 and the optical machine support 4 to complete the assembly operation of various optical parts.

[0098] The second step is to assemble the AR connection device with the appearance parts that have been assembled with various optical parts. The process is as follows:

[0101] Afterwards, the fixing parts are used to pass through the aligned mounting holes 2 and fixing holes 20 in sequence, so that the first appearance part 15 and the AR connecting device as well as the second appearance part 16 are tightly fixedly connected.

[0102] Finally, the AR glasses temples 17 are installed on the extension portion of the exterior component to complete the entire installation operation of the AR glasses device.
