The second adjustment sub-part can drive the camera to rotate around three mutually perpendicular axes, and together with the first adjustment sub-part, adjust the position of the camera so that the camera corresponds to the optical path for transmitting optical signals.

[0018] Optionally, the lens adjustment assembly includes:

[0019] The first part is disposed above the lens along a third direction and abuts against the lens;

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0044] Smart glasses refer to a general term for wearable glasses devices that have their own operating system, similar to smartphones, and can achieve various functions through software installation. AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality), and XR (Extended Reality) smart glasses have attracted attention from different customer groups. Extended Reality includes various forms such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR). In other words, XR is actually a general term encompassing AR, VR, and MR. XR is divided into multiple levels, ranging from virtual worlds input through limited sensors to fully immersive virtual worlds. This application uses AR-type smart glasses as an example for illustration and should not be construed as a limitation on the types of smart glasses.

[0045] Structurally, smart glasses are divided into monocular and binocular types. For example, AR glasses can be divided into monocular and binocular structural forms. Monocular products suffer from poor user experience due to factors such as a small field of view, while binocular products, with their larger field of view and better user experience, have gradually become the market mainstream.

[0046] In the manufacturing process of smart glasses, in addition to fabricating and assembling the various components, imaging tests and adjustments are also required. After adjustment, the glasses are fixed with adhesive to form the finished product. Whether it's a monocular or binocular product, imaging adjustment or correction is necessary. Binocular imaging adjustment involves adjusting the two lenses and their corresponding optical engines to ensure the imaging positions of the two lenses overlap, or to achieve optical coupling, reducing dizziness caused by non-overlapping images. Monocular imaging position adjustment is similar to binocular adjustment; it involves adjusting the imaging position to suit human vision, improving clarity and enhancing the user experience.

[0047] However, in related technologies, the process of imaging testing and adjustment of smart glasses can easily lead to frame deformation.

[0048] To reduce the occurrence of the above situations, this application provides a testing device for smart glasses, which will be described below in conjunction with the accompanying drawings.

[0049] For example, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of smart glasses provided in an embodiment of this application. This application provides a smart glasses 1, which includes a frame 10, lenses 11, and an optical engine 12. The frame 10 supports the lenses 11 and the optical engine 12. The frame 10 may include a front frame and side frames (not shown in the figure). The front frame has a lens hole, the size of which is approximately equal to that of the lens 11, to mount the lens 11 onto the front frame. The side frames are located on one side of the front frame, and can be bent and connected to the front frame, and can be integrally formed during manufacturing. The smart glasses 1 may also include temples (not shown in the figure), which are rotatably connected to the side frames. The temples cooperate with the front frame for wear by the user. For AR glasses, since perspective is required to see both the real external world and virtual information, the imaging system cannot obstruct the view. Therefore, the optical engine 12 can be located in the side frame.

[0050] The optomechanism 12 emits an illumination beam along the emission path and modulates the illumination beam into image light, which is then transmitted to a projection imaging system, such as lens 11, for projection imaging. Lens 11, which can be called an optical waveguide, has a transmission area and an entrance area (not shown in the figure). In AR glasses, "total internal reflection" is crucial for light to travel without loss or leakage during transmission; that is, light travels through the waveguide like a snake, reflecting back and forth without being transmitted. After the optomechanism 12 completes the imaging process, the waveguide couples the light into its glass substrate, transmitting the light to the front of the eye and releasing it through the principle of "total internal reflection." This is the imaging principle of smart glasses 1.

[0051] It should be noted that when the smart glasses 1 are assembled, the lens 11 and the optical engine 12 are respectively mounted on the frame 10. During the assembly process, the frame 10 can be placed on the operating table first, and the lens 11 and the optical engine 12 can be clamped on the testing device. After adjusting the position of the lens 11 and the position of the optical engine 12 to adjust the imaging position, such as binocular imaging adjustment or monocular imaging position adjustment, the lens 11 and the optical engine 12 are fixed on the frame 10, thus forming a... Figure 1 The smart glasses shown are 1.

[0052] For example, please refer to Figure 1 And see Figure 2 As shown, Figure 2 This is a schematic diagram of the first angle of the testing device for smart glasses provided in an embodiment of this application. This application provides a testing device 2 for smart glasses, used to adjust the visual imaging of smart glasses 1. The testing device 2 may have a first direction X, a second direction Y, and a third direction Z that are mutually perpendicular. The third direction Z is also the direction of gravity. It should be understood that the first direction X, the second direction Y, and the third direction Z are directions defined for ease of description and should not be construed as limitations on the testing device 2.

[0053] The testing device 2 includes an operating table 20, a base 21, a fixing component 22, an optical-mechanical adjustment component 23, a lens adjustment component 24, and a camera component 25.

[0054] The operating table 20 serves as the support platform for the testing device 2, supporting components such as the base 21, fixing assembly 22, optomechanical adjustment assembly 23, lens adjustment assembly 24, and camera assembly 25. The operating table 20 also has a set height along the third direction Z, facilitating operations such as clamping the smart glasses 1. The operating table 20 can be in the shape of a cuboid, cube, or prism, and a channel 201 can be provided. This design reduces material costs while ensuring the load-bearing capacity of the operating table 20, and also facilitates its installation and fixation in a designated position, preventing instability caused by movement.

[0055] The base 21 is mounted on the operating table 20 and serves to support the lens frame 10, the fixing assembly 22, the optomechanical adjustment assembly 23, and the lens adjustment assembly 24. The orthographic projection of the base 21 onto the operating table 20 lies within the operating table 20. Components requiring different heights can be arranged on the base 21 and the operating table 20. The base 21 can be square to match the shape of the operating table 20, thereby improving the aesthetics of the testing device 2.

[0056] Please combine Figure 1 and Figure 2 And see Figure 3 As shown, Figure 3 This is a first structural diagram of the testing device for smart glasses provided in this application embodiment, with some structures removed. A fixing component 22 is disposed on the base 21 and is used to fix the frame 10. For example, the fixing component 22 may include a fixing base 220 and a fixing part 221. The fixing base 220 and the base 21 can be connected by a connector such as a screw. The fixing part 221 is disposed on the fixing base 220 and can fix the frame 10 on the fixing base 220 to prevent misalignment of the optical engine 12 and the lens 11 caused by movement of the frame 10.

[0057] Optical mechanism adjustment component 23 is disposed on base 21. Optical mechanism adjustment component 23 is used to connect with optical mechanism 12 to drive optical mechanism 12 to move.

[0058] The lens adjustment assembly 24 is used to clamp the lens 11 to drive the lens 11 to move, and cooperates with the optomechanical adjustment assembly 23 to adjust the imaging position of the smart glasses 1.

[0059] The camera assembly 25 includes a camera 250, which is disposed in the optical path of the lens 11 for transmitting light signals, to collect the light signals emitted by the optical engine 12 transmitted by the lens 11. Exemplarily, in this embodiment, the camera 250 can be moved above the lens 11 along a third direction Z to correspond to the area where the lens 11 emits light signals, thereby enabling the camera 250 to collect light signals. It should be noted that this embodiment uses AR glasses as an example. In AR glasses, to reduce obstruction of the user's view, the optical engine 12 is disposed on the side of the frame 10. The lens 11, also called an optical waveguide, can transmit the light signals emitted by the optical engine 12 and reflect them through the emission area to objects such as the human eye or the camera 250.

[0060] In the testing device 2 for smart glasses provided in this application embodiment, during the imaging test of smart glasses 1, the frame 10 is fixed to the base 21 by using the fixing component 22 instead of suspending the frame in the air. This reduces the damage to the frame 10 caused by the force exerted when adjusting the position of the optical engine 12 and the lens 11, thereby reducing the occurrence of deformation of the frame 10.

[0061] It should be noted that the camera 250 in the testing device 2 acts as the human eye. The camera 250 receives relevant information emitted by the optical waveguide, that is, it determines whether the imaging position meets the requirements by acquiring the image transmitted by the lens 11. Therefore, after fixing the smart glasses 1, the camera 250 needs to be adjusted to a preset position, and then the positions of the optical engine 12 and the lens 11 are adjusted to adjust the binocular imaging overlap or the monocular imaging position. The preset position of the camera 250 can be set with reference to the distance between the human eye and the smart glasses 1.

[0062] The adjustment of the position of the camera 250 is achieved by setting an adjustment component. For example, the camera assembly 25 also includes an adjustment part 252. One end of the adjustment part 252 is fixed to the operating table 20 and spaced apart from the base 21. The other end of the adjustment part 252 is used to fix the camera 250. The adjustment part 252 can drive the camera 250 to move so that the camera 250 corresponds to the optical path of the lens 11 that transmits light signals.

[0063] For example, please refer to Figures 1 to 3 And see Figure 4 As shown, Figure 4This is a schematic diagram of the camera assembly in the testing device for smart glasses provided in this application embodiment. The adjustment unit 252 includes a first adjustment sub-unit 2520 and a second adjustment sub-unit 2522. The first adjustment sub-unit 2520 is mounted on the operating table 20 and can move relative to the operating table 20 along a first direction X, a second direction Y, and a third direction Z, respectively. One end of the second adjustment sub-unit 2522 is connected to the first adjustment sub-unit 2520 to follow the movement of the first adjustment sub-unit 2520, and the other end of the second adjustment sub-unit 2522 is connected to the camera 250. The second adjustment sub-unit 2522 can drive the camera 250 to rotate around three mutually perpendicular axes, and together with the first adjustment sub-unit 2520, adjust the position of the camera 250 so that the camera 250 corresponds to the optical path through which the lens 11 transmits light signals.

[0064] Understandably, the adjustment unit 252 has six degrees of freedom, or six axes. The first adjustment sub-unit 2520, which is a horizontal three-axis unit, is used to adjust the position of the camera 250 along the first direction X, the second direction Y, and the third direction Z. The second adjustment sub-unit 2522, which is a rotational three-axis unit, is used to adjust the rotation of the camera 250 along three mutually perpendicular directions. By adjusting the position of the camera 250 through the six-degree-of-freedom adjustment unit 252, the position of the camera 250 in space can be precisely adjusted, thereby improving the positional accuracy of the camera 250 and thus improving the accuracy of imaging tests.

[0065] It should be noted that because the adjustment unit 252 has many components, its overall weight is relatively heavy. If placed on the base 21, it may easily cause the base 21 to become unbalanced. Furthermore, the adjustment unit 252 includes a first adjustment sub-unit 2520 and a second adjustment sub-unit 2522. The first adjustment sub-unit 2520 and the second adjustment sub-unit 2522 need to work together to achieve movement in six directions. Therefore, there is a set distance between the first adjustment sub-unit 2520 and the second adjustment sub-unit 2522, and the second adjustment sub-unit 2522 needs to extend and be raised relative to the first adjustment sub-unit 2520 so that there are no obstructions when the camera 250 is facing the lens 11. The set distance between the base 21 and the operating table 20 facilitates the alignment of the camera 250 and the lens 11's emission area.

[0066] The base 21 and the operating table 20 can be slidably connected so that after the position of the lens 11 is adjusted, the base 21 can be slid relative to the operating table 20 to remove the cover and cover of the camera 250, so as to facilitate the glue fixation operation of the lens 11 and the frame 10.

[0067] For example, please refer to Figures 1 to 4 And see Figure 5 As shown, Figure 5This is a schematic diagram of the second angle of the testing device for smart glasses provided in this application embodiment. A first sliding portion 210 is provided on the side of the base 21 facing away from the fixing component 22. A second sliding portion 202 is provided on the side of the operating table 20 facing the base 21. The second sliding portion 202 and the first sliding portion 210 are slidably connected along the second direction Y, so that the lens 11 moves closer to or further away from the camera 250. For example, a first adjustment sub-portion 2520 can be provided at one end of the operating table 20 along the second direction Y, and a second adjustment sub-portion 2522 can be provided on the first adjustment sub-portion 2520 and extend towards the other end of the operating table 20 along the second direction Y. When the base 21 slides relative to the operating table 20, it moves closer to or further away from the first adjustment sub-portion 2520, thereby achieving the movement of the lens 11 closer to or further away from the camera 250.

[0068] The first sliding part 210 and the second sliding part 202 can be a combination of a slide rail and a slide groove. For example, the second sliding part 202 can be a slide rail, and the first sliding part 210 can be a slide groove. The slide groove slides along the slide rail to drive the relative movement between the base 21 and the operating table 20.

[0069] For example, please refer to Figures 1 to 5 And see Figures 6 to 9 As shown, Figure 6 This is a schematic diagram of a second structure of the testing device for smart glasses provided in this application, with some parts removed. Figure 7 for Figure 6 The diagram shows a cross-sectional view of the testing device along the AA direction. Figure 8 for Figure 6 The diagram shows a cross-sectional view of the testing device along the BB direction. Figure 9 for Figure 8 The diagram shows a partial structural diagram of the test device shown. The lens adjustment assembly 24 includes a first part 240 and a second part 242. The first part 240 is positioned above the lens 11 along the third direction Z and abuts against the lens 11. The second part 242 is positioned below the lens 11 along the third direction Z and corresponds to the first part 240. One end of the second part 242 abuts against the lens 11, and the other end is positioned on the base 21. It can be understood that the first part 240 and the second part 242 clamp the lens 11 from both sides. A pivot can be set at the lens frame 10 corresponding to the image exit position in the lens 11. When the first part 240 and the second part 242 are pressed down or lifted along the third direction Z, the lens 11 rotates up and down around the pivot. Of course, this is a small-range rotation to adjust the imaging position.

[0070] The second part 242 may include an elastic portion 2420. The elastic portion 2420 facilitates the synchronous movement of the first part 240 and the second part 242, and also facilitates the fixing of the lens adjustment assembly 24. It is understood that without the elastic portion, the second part is rigidly connected to the base, making lens adjustment impossible. In this embodiment, the elastic portion 2420 in the second part 242 facilitates the fixing of the lens adjustment assembly 24, reducing damage to the lens 11 caused by the suspension of the lens adjustment assembly. Furthermore, compared to directly pressing down or lifting the lens 11, using the elastic portion 2420 to press down or lift the lens 11 improves the stability of the movement and the adjustment accuracy of the lens 11.

[0071] For example, the lens adjustment assembly 24 has a first state and a second state. In the first state, when the first portion 240 moves downward along the third direction Z, the lens 11 is driven to rotate downward, and the elastic portion 2420 contracts. In the second state, when the first portion 240 moves upward along the third direction Z, the lens 11 is driven to rotate upward, and the elastic portion 2420 returns to its original position.

[0072] In some embodiments, the elastic part 2420 can help the lens 11 to move upward, so as to save the force required to lift the lens 11.

[0073] Regarding the position of the lens adjustment assembly 24 relative to the lens 11, since the first part 240 and the second part 242 correspond, the relative position of the first part 240 and the lens 11 will be used as an example for explanation. For instance, the first part 240 abuts against the center of the lens 11 along the first direction X, near its edge; that is, it is located on the center line of the lens 11 along the first direction X, near the edge of the lens 11. The edge and center are relative concepts. Alternatively, the first part 240 may be positioned at one end of the lens 11 along the second direction Y, for example, at the center of the end of the lens 11 along the second direction Y that is away from the adjustment part 252, thereby allowing adjustment of the vertical movement of the image.

[0074] For example, the first portion 240 can also abut against the center of the lens 11 along the second direction X and near its edge, that is, selected along the center line of the lens 11 along the second direction X and near the edge of the lens 11. In other words, the first portion 240 can be disposed at one end of the lens 11 along the first direction X, for example, the first portion 240 can be disposed at the center of the end of the lens 11 along the first direction X and near the optical engine 12, thereby allowing adjustment of the horizontal movement of the image.

[0075] It is understood that the position adjustment for monocular imaging can refer to the position setting of the first part 240 in the two methods described above. In some embodiments, two lens adjustment components can also be provided for monocular imaging adjustment to improve the accuracy of monocular imaging adjustment.

[0076] For binocular imaging adjustment, the setting position of the first part 240 relative to the lens 11 can be as follows: The test device 2 may include two lens adjustment components 24, which are set at intervals. The first part 240 of one of the two lens adjustment components 24 is set at one end of one lens 11 in the smart glasses 1 along the second direction Y, and the other first part 240 is set at one end of the other lens 11 in the smart glasses 1 along the first direction X. The two lens adjustment components 24 cooperate to achieve binocular imaging adjustment, that is, one lens adjustment component 24 realizes the vertical image adjustment, and the other lens adjustment component 24 realizes the horizontal image adjustment. There is no need to configure four lens adjustment components 24 for the two lenses 11, which is convenient, quick, and has high adjustment accuracy.

[0077] For example, please refer to Figures 1 to 9 And see Figure 10 As shown, Figure 10 This is a schematic diagram of the optical mechanism adjustment assembly in the testing device for smart glasses provided in this application embodiment. The optical mechanism adjustment assembly 23 includes a clamping part 230 and a rotating part 231. The clamping part 230 is connected to the frame 10 to fix the optical mechanism 12. The rotating part 231 is connected to the clamping part 230 and can drive the optical mechanism 12 to rotate along its axial direction to adjust the binocular horizontal angle and the left and right eye imaging angle.

[0078] For example, the optomechanical adjustment assembly 23 further includes a movable part 232, which is disposed on the base 21 and rotatably connected to the rotating part 231, so that the rotating part 231 can rotate relative to the movable part 232. Furthermore, the movable part 232 can drive the rotating part 231 and the optomechanical assembly 12 to move along the first direction X, the second direction Y, and the third direction Z, respectively, to adjust the horizontal and vertical deviations of the left and right eye imaging positions.

[0079] It should be noted that there can be one optical-mechanical adjustment component 23, which is used to adjust the monocular imaging position. There can also be two optical-mechanical adjustment components 23, which can be arranged on opposite sides of the smart glasses 1 along the first direction X, so as to adjust the two optical engines 12 of the smart glasses 1 respectively.

[0080] For example, the testing device 2 also includes a control board 26, which is mounted on the base 21 and electrically connected to the optical engine 12 to drive the optical engine 12 to emit light signals. It is understood that since the smart glasses 1 is not equipped with a battery at this time, it cannot be powered on. To simulate the imaging effect of the smart glasses 1, the control board 26 is provided. The control board 26 can store software for the smart glasses 1 to display according to preset rules, thereby driving the display of the light signals from the optical engine 12. The number of control boards 26 corresponds to the number of optical engines 12. For example, if the testing device 2 is used to test and adjust binocular eye closure, then there are two control boards 26 and two optical engines 12, each driving the display of the optical engine 12.

[0081] It should be noted that the adjustment parts 252 of the aforementioned optical engine adjustment assembly 23, lens adjustment assembly 24, and camera assembly 25 can be adjusted manually or equipped with electric drive components to achieve automated operation; no specific limitation is made here.

[0082] Taking binocular combined imaging test adjustment as an example, the imaging adjustment process of the smart glasses 1 in this embodiment can be as follows: The optical engine adjustment component 23 is fixed to the frame 10, for example, by using screws. Then, the lens 11 is assembled onto the lens adjustment component 24. The assembled lens adjustment component 24 and lens 11 are then installed onto the frame 10. The frame 10 is assembled onto the base 21 and fixed using the fixing component 22. The optical engine 12 is assembled onto the optical engine adjustment component 23 and fixed with screws. The lens adjustment component 24 is adjusted to the adjustment position, and adhesive is evenly applied around the lens 11, with symmetrical adhesive applied to two points on the optical engine 12. The base 21 is slid to the adjusted position of the camera 250, so that the lens 11 corresponds to the camera 250. First, the left and right optical engines 12 are adjusted to rotate around the third direction Z. Then, the right lens 11 is adjusted to rotate along the second direction Y, and the left lens 11 is adjusted to rotate along the first direction X. After adjustment, move the base 21 to move the lens 11 away from the camera 250, and cure the pre-applied adhesive around the lens 11 using a UV lamp. After the pre-applied adhesive has cured, move the base 21 below the camera 250 and check for any misalignment when the eyes are closed. If there is misalignment, clean off the adhesive and readjust the positions of the optical engine 12 and the lens 11. If there is no misalignment, cure the adhesive applied to both points on the optical engine 12 and ensure that the pre-applied adhesive around the lens 11 is completely cured. After curing, move the base 21 below the camera 250 again and check for any misalignment when the eyes are closed a second time. If there is misalignment, clean off the adhesive and readjust the positions of the optical engine 12 and the lens 11. If there is no misalignment, the tested frame 10, lens 11, and optical engine 12 can be removed.

[0083] In the testing apparatus 2 for smart glasses provided in this application embodiment, during the imaging test of smart glasses 1, the frame 10 is fixed to the base 21 by using the fixing component 22, instead of suspending the frame in the air. This reduces the damage to the frame 10 caused by the force exerted when adjusting the position of the optical engine 12 and the lens 11, thereby reducing the occurrence of frame 10 deformation. By cooperating with the optical engine adjustment component 23 and the lens adjustment component 24 to adjust the imaging of smart glasses 1, coordinated binocular eye-closing adjustment can be performed, increasing the eye-closing adjustment range.
