Description

Technical Field

[0001] The present application relates to the technical field of augmented reality devices, and in particular to a binocular image adjustment device. Background Art

[0002] With the continuous development of information technology, augmented reality (AR) technology has gradually attracted widespread attention in recent years. AR technology is a technology that cleverly integrates virtual information with the real world. It simulates virtual information generated by computers and applies it to the real world. The two types of information complement each other, thus achieving an "enhancement" of the real world.

[0003] During the AR glasses production process, some manufacturing errors are unavoidable. The position of the optical waveguide may be slightly off, or the lens installation angle may not be completely consistent. These manufacturing errors can cause differences in the transmission paths of the left and right eye images, resulting in image misalignment.

[0004] The binocular AA (Active Alignment) process is an important step in ensuring that the waveguide lens display is fully visible to the human eye. Binocular AA achieves binocular image formation by adjusting the position and angle of the light engine relative to the waveguide lens.

[0005] However, the existing binocular AA process only considers the adjustment of the six degrees of freedom of the light engine relative to the waveguide lens. The magnitude of the force between the light engine and the waveguide lens can only be determined by human feeling, resulting in a lack of accuracy and low efficiency of binocular AA.

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element through an intervening element.

For example, the terms "first," "second," and so on are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, the term "first" or "second" may explicitly or implicitly include at least one of the features.

[0038] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0039] With the continuous development of information technology, augmented reality (AR) technology has gradually attracted widespread attention in recent years. AR technology is a technology that cleverly integrates virtual information with the real world. It simulates virtual information generated by computers and applies it to the real world. The two types of information complement each other, thus achieving an "enhancement" of the real world.

[0040] The binocular AA (Active Alignment) process is a crucial step in ensuring that the waveguide lens display is fully visible to the human eye. Binocular AA achieves binocular image formation by adjusting the position and angle of two light engines (also known as optical machines) relative to the waveguide lens. Specifically, binocular AA is known as active alignment in optics and is suitable for the precise alignment and assembly of optical components, such as lenses, LED screens, and holders. The basic principle is to automatically adjust the precise alignment of optical components (such as lenses, LED screens, and holders) in six degrees of freedom (X / Y / Z translation and θx / θy / θz rotation) through real-time imaging analysis, finding the optimal assembly relationship between the three to ensure optimal image quality.

[0041] Due to assembly precision, the pressure exerted by the two light engines on the waveguide lens may be different. However, the existing binocular AA process only considers the adjustment of the light engine's six degrees of freedom relative to the waveguide lens (X / Y / Z translation and θx / θy / θz rotation). It fails to consider the force exerted by the light engine relative to the waveguide during the binocular AA process. The force exerted by the light engine and the waveguide lens can only be determined by human perception, resulting in poor binocular AA precision and low efficiency.

[0042] Therefore, the embodiment of the present application proposes a binocular image combination adjustment device, which aims to solve the problems of insufficient accuracy and low efficiency of binocular AA in the current stage.

[0043] See also Figures 1 to 3 The present application provides a binocular image combination adjustment device 100, comprising a first adjustment mechanism 10, a second adjustment mechanism 20, a third adjustment mechanism 30, a first pressure detection mechanism 40, and a second pressure detection mechanism 50. The first adjustment mechanism 10 comprises a first adjustment assembly 11 and a first support structure 12. The first support structure 12 is used to mount a first light engine 200, and the first adjustment assembly 11 is used to adjust the posture of the first light engine 200. The second adjustment mechanism 20 comprises a second adjustment assembly 21 and a second support structure 22. The second support structure 22 is used to mount a second light engine 300, and the second adjustment assembly 21 is used to adjust the posture of the second light engine 300. The third adjustment mechanism 30 is disposed between the first adjustment mechanism 10 and the second adjustment mechanism 20. The third adjustment mechanism 30 comprises a third adjustment assembly 31 and a third support structure 32. The third support structure 32 is used to mount a front frame module 400. The front frame module 400 provides a mounting and fixing location for other components of the AR glasses, such as lenses, optical coupling modules, and sensors. Sufficient strength and stability are required to ensure these components do not loosen or shift during use, ensuring the normal operation of the AR glasses. The third adjustment assembly 31 is used to adjust the posture of the front frame module 400. The first support structure 12 extends to the third support structure 32, allowing the first light engine 200 to press against the front frame module 400, and the second support structure 22 extends to the third support structure 32, allowing the second light engine 300 to press against the front frame module 400. The first pressure detection mechanism 40 is connected between the first support structure 12 and the first light engine 200. The first pressure detection mechanism 40 is used to detect the pressure applied by the first light engine 200 to the front frame module 400 and generate a first signal. The second pressure detection mechanism 50 is connected between the second support structure 22 and the second light engine 300. The second pressure detection mechanism 50 is used to detect the pressure applied by the second light engine 300 to the front frame module 400 and generate a second signal.

[0044] The binocular combination adjustment device 100 of the embodiment of the present application can accurately feedback the pressure applied by the first light engine 200 to the front frame module 400 through the provision of the first pressure detection mechanism 40, and can accurately feedback the pressure applied by the second light engine 300 to the front frame module 400 through the provision of the second pressure detection mechanism 50. This solves the problem of relying solely on human perception to determine the magnitude of the force applied by the light engine and the front frame module 400, thereby improving the accuracy and efficiency of binocular AA.

[0045] In addition, through the precise feedback of the first pressure detection mechanism 40 and the second pressure detection mechanism 50, it is possible to adjust the pressure exerted by the first light engine 200 and the second light engine 300 on the front frame module 400 according to the detected pressure information during binocular AA. This not only prevents the first light engine 200 and / or the second light engine 300 from excessively squeezing the front frame module 400 and causing deformation of the front frame module 400, but also protects the first light engine 200 and / or the second light engine 300 from excessive contact force that may damage the front end lens of the first light engine 200 and / or the second light engine 300, thereby ensuring the smooth progress of binocular AA and improving the product yield.

[0046] See also Figure 4 In some embodiments, the front frame module 400 includes two waveguide lenses 410, respectively positioned corresponding to the first adjustment mechanism 10 and the second adjustment mechanism 20. The first light engine 200 presses against one of the waveguide lenses 410, while the second light engine 300 presses against the other waveguide lens 410. In actual use, the first light engine 200 and the second light engine 300 output the same image to the two waveguide lenses 410, so that the images output by the first light engine 200 and the second light engine 300 can be fused after entering the human eye through the waveguide lenses 410.

[0047] Optionally, in the present application, an electronic device such as a camera or an image sensor can be provided on the third adjustment mechanism 30, and the image of the image output by the first light engine 200 and the second light engine 300 after passing through the waveguide lens 410 is obtained by the camera or image sensor, thereby simulating the human eye to observe the image, identify and calculate the offset position and distance of the image, and then fine-tune the optical waveguide or waveguide lens 410 through the third adjustment mechanism 30 to achieve binocular AA.

[0048] In some embodiments, the binocular image combination adjustment device 100 further includes a controller configured to receive the first signal and the second signal and, upon detecting a difference between the pressure applied by the first light engine 200 on the waveguide lens 410 and the pressure applied by the second light engine 300 on the waveguide lens 410, control the first adjustment component 11 to adjust the pressure of the first light engine 200 relative to the waveguide lens 410 and / or control the second adjustment component 21 to adjust the pressure of the second light engine 300 relative to the waveguide lens 410, thereby reducing the difference between the pressure applied by the first light engine 200 on the waveguide lens 410 and the pressure applied by the second light engine 300 on the waveguide lens 410. Thus, the controller can adjust the pressure applied by the first light engine 200 and the second light engine 300 on the waveguide lens 410 to ensure that the pressures applied by the first light engine 200 and the second light engine 300 on the waveguide lens 410 are close to or equal during binocular AA, thereby balancing the pressures applied by the first light engine 200 and the second light engine 300 on the waveguide lens 410 on both sides during binocular AA.

[0049] In some embodiments, the pressure applied by the first light engine 200 to the waveguide lens 410 is a first pressure, and the pressure applied by the second light engine 300 to the waveguide lens 410 is a second pressure; the controller is configured to control the first adjustment component 11 to adjust the pressure of the first light engine 200 relative to the waveguide lens 410 to reduce the first pressure so that the first pressure and the second pressure are close to or the same when detecting that the first pressure is greater than the second pressure; alternatively, the controller is configured to control the second adjustment component 21 to adjust the pressure of the second light engine 300 relative to the waveguide lens 410 to reduce the second pressure so that the first pressure and the second pressure are close to or the same when detecting that the second pressure is greater than the first pressure. Therefore, when the controller detects that the pressure exerted by the first light engine 200 on the waveguide lens 410 and the pressure exerted by the second light engine 300 on the waveguide lens 410 are different, the smaller pressure value is selected for adjustment, so that the pressure exerted by the first light engine 200 and the second light engine 300 on the waveguide lens 410 on both sides is close to or the same, thereby improving the image combination accuracy and reducing the squeezing force of the first light engine 200 and the second light engine 300 relative to the waveguide lens 410, thereby preventing the waveguide lens 410 from being squeezed and deformed.

[0050] In some embodiments, the first adjustment assembly 11, the second adjustment assembly 21, and the third adjustment assembly 31 have the same structure. For example, the first adjustment assembly 11, the second adjustment assembly 21, and the third adjustment assembly 31 can all use a six-axis device, which can be a manually assembled six-axis device, an electric six-axis assembly, a six-axis parallel robot, or other device capable of achieving six degrees of freedom.

[0051] Exemplarily, the first adjustment component 11 adjusts the posture of the first light engine 200 by adjusting the spatial three-dimensional position and three-axis posture angle of the first light engine 200, the second adjustment component 21 adjusts the posture of the second light engine 300 by adjusting the spatial three-dimensional position and three-axis posture angle of the second light engine 300, and the second adjustment component 21 adjusts the posture of the waveguide lens 410 by adjusting the spatial three-dimensional position and three-axis posture angle of the waveguide lens 410, so that the image positions projected by the first light engine 200 and the second light engine 300 are adjusted to a specified binocular image position. When the first light engine 200 and the second light engine 300 can output the same image and couple it into the waveguide lens 410, the above adjustment ensures that the images output by the first light engine 200 and the second light engine 300 can be fused when entering the human eye through the waveguide lens 410.

[0052] Then, through the precise feedback of the first pressure detection mechanism 40 and the second pressure detection mechanism 50, the pressure of the first light engine 200 and the second light engine 300 relative to the waveguide lens 410 can be adjusted, and the first light engine 200, the second light engine 300 and the waveguide lens 410 can be fixed by glue while ensuring the image is combined. This ensures that the light projected by the light engine can accurately pass through the waveguide lens 410 and form a clear, ghost-free virtual image in the user's eyes.

[0053] In some embodiments, the first adjustment mechanism 10 and the second adjustment mechanism 20 are symmetrically arranged on both sides of the third adjustment mechanism 30, thereby helping to ensure that the light can maintain similar paths and angles when projected from the left and right light engines, thereby reducing ghosting generated in the waveguide lens 410 and improving image combination accuracy.

[0054] In some embodiments, the binocular image combination adjustment device 100 further includes a fixed base 60 , and the first adjustment mechanism 10 , the second adjustment mechanism 20 , and the third adjustment mechanism 30 are installed side by side on the fixed base 60 for easy installation and positioning.

[0055] See also Figure 5 In some embodiments, the first pressure detection mechanism 40 and the second pressure detection mechanism 50 may have the same structure and size. The fixing method of the first pressure detection mechanism 40 and the first light engine 200 and the fixing method of the second pressure detection mechanism 50 and the second light engine 300 may also be the same, so as to facilitate balancing the pressure of the first light engine 200 and the second light engine 300 relative to the waveguide lens 410.

[0056] In some embodiments, the first pressure detection mechanism 40 is fixed to the first support structure 12, and the first light engine 200 is adsorbed onto the side of the first pressure detection mechanism 40 facing the waveguide lens 410. Thus, affixing the first light engine 200 to the first pressure detection mechanism 40 via adsorption not only ensures uniform contact and force distribution between the first light engine 200 and the first pressure detection mechanism 40, thereby improving the stability and reliability of the overall structure, but also effectively reduces the relative position of the first light engine 200 and the first pressure detection mechanism 40 caused by vibration. Furthermore, the use of adsorption reduces the number of parts required during assembly, thereby simplifying the assembly process and improving production efficiency. When maintenance or replacement of the first light engine 200 or the first pressure detection mechanism 40 is required, adsorption makes disassembly faster and more convenient, reducing maintenance costs and time.

[0057] In some embodiments, the first pressure detection mechanism 40 includes a first pressure sensor and a first adsorption structure. The first light engine 200 is adsorbed to the first pressure sensor via the first adsorption structure. The first pressure sensor is configured to detect the pressure exerted by the first light engine 200 on the waveguide lens 410 and emit a first signal. Thus, the provision of the first pressure sensor facilitates detection of the pressure exerted by the first light engine 200 on the waveguide lens 410 and emits a first signal, providing precise feedback of pressure information. This facilitates adjusting the pressure exerted by the first light engine 200 and the second light engine 300 on the waveguide lens 410, respectively, based on the detected pressure information during binocular AA, thereby improving image convergence accuracy.

[0058] In some embodiments, the first adsorption structure may employ a negative pressure device to generate negative pressure to adsorb the first light engine 200 to the first pressure sensor. For example, the negative pressure device may be a vacuum pump or other device capable of generating negative pressure, as long as it is capable of adsorbing the first light engine 200 to the first pressure sensor.

[0059] In some embodiments, the first suction structure includes a first vacuum pump and a first suction cup. The first vacuum pump is connected to a first pressure sensor, and the first suction cup is connected to the first vacuum pump. The first light engine 200 is attached to the first suction cup. Thus, the negative pressure generated by the first vacuum pump securely holds the first light engine 200 via the first suction cup, enabling precise control of the position of the first light engine 200. This avoids the deviation and misalignment that can occur with traditional mechanical fixing methods, thereby improving assembly accuracy.

[0060] In some embodiments, the second pressure detection mechanism 50 is fixed to the second support structure 22, and the second light engine 300 is adsorbed onto the side of the second pressure detection mechanism 50 facing the waveguide lens 410. Thus, affixing the second light engine 300 to the second pressure detection mechanism 50 via adsorption not only ensures uniform contact and force distribution between the second light engine 300 and the second pressure detection mechanism 50, thereby improving the stability and reliability of the overall structure, but also effectively reduces the relative position of the second light engine 300 and the second pressure detection mechanism 50 caused by vibration. Furthermore, the use of adsorption reduces the number of parts required during assembly, thereby simplifying the assembly process and improving production efficiency. When maintenance or replacement of the second light engine 300 or the second pressure detection mechanism 50 is required, adsorption makes disassembly faster and more convenient, reducing maintenance costs and time.

[0061] In some embodiments, the second pressure detection mechanism 50 includes a second pressure sensor and a second adsorption structure. The second light engine 300 is adsorbed to the second pressure sensor via the second adsorption structure. The second pressure sensor is used to detect the pressure applied by the second light engine 300 to the waveguide lens 410 and emit a second signal. Thus, the provision of the second pressure sensor facilitates detection of the pressure applied by the second light engine 300 to the waveguide lens 410 and emits a second signal, providing precise feedback of pressure information. This facilitates adjusting the pressure applied by the first and second light engines 200 and 300 to the waveguide lens 410, respectively, based on the detected pressure information during binocular AA, thereby improving image convergence accuracy.

[0062] In some embodiments, the second adsorption structure may employ a negative pressure device to generate negative pressure to adsorb the second light engine 300 to the second pressure sensor. For example, the negative pressure device may be a vacuum pump or other device capable of generating negative pressure, as long as it is capable of adsorbing the second light engine 300 to the second pressure sensor.

[0063] In some embodiments, the second suction structure includes a second vacuum pump and a second suction cup. The second vacuum pump is connected to a second pressure sensor, and the second suction cup is connected to the second vacuum pump. The second light engine 300 is attached to the second suction cup. Thus, the negative pressure generated by the second vacuum pump securely holds the second light engine 300 via the second suction cup, enabling precise control of the position of the second light engine 300. This avoids the deviation and misalignment that can occur with traditional mechanical fixing methods, thereby improving assembly accuracy.

[0064] See also Figure 4In some embodiments, the first support structure 12 includes a first base 121 and a first extension arm 122. The first base 121 is disposed on the first adjustment assembly 11. The first extension arm 122 has a first end and a second end opposite each other. The first end is connected to the first base 121, and the second end extends above the waveguide lens 410. The second end is connected to the side of the waveguide lens 410 facing the first light engine 200. Thus, the arrangement of the first base 121 and the first extension arm 122 facilitates supporting the first light engine 200 above one side of the waveguide lens 410, thereby helping the light projected by the first light engine 200 to accurately pass through the waveguide lens 410.

[0065] In some embodiments, the second support structure 22 includes a second base 221 and a second extension arm 222. The second base 221 is disposed on the second adjustment assembly 21. The second extension arm 222 has opposing third and fourth ends. The third end is connected to the second base 221, and the fourth end extends above the waveguide lens 410. The second light engine 300 is connected to the side of the fourth end facing the waveguide lens 410. Thus, the arrangement of the second base 221 and the second extension arm 222 facilitates supporting the second light engine 300 above the other side of the waveguide lens 410, thereby helping the light projected by the first light engine 200 to accurately pass through the waveguide lens 410.
