Description

Technical Field

[0001] The utility model relates to the technical field of AR glasses, in particular to a binocular optical engine assembly and an AR glasses. Background Art

[0002] In AR glasses, there is a way of binocular image synthesis. First, the image synthesis of a single BB (BirdBath) optical engine is completed (meeting the two indicators of MTF and boresight), and then the single BB optical engine is assembled onto the binocular bracket. MTF (modulation transfer function) combines two indicators of resolution and contrast, representing the ability of the imaging system to convert resolution into contrast. Boresight represents the visual axis difference, including the errors of the two images on the image side and the eye side in the three dimensions of horizontal, vertical, and rotation. The existing BB optical engine is usually directly positioned and fixed by bolts when installed on the binocular optical engine bracket. Due to the assembly error existing in the bolt fastening itself, the binocular image synthesis accuracy of the AR glasses is not high. The existing AA image synthesis can only improve the quality of single-eye image synthesis. When it is necessary to adjust a single optical engine to ensure the quality of binocular image synthesis, it is difficult to accurately move a single optical engine by manually adjusting the bolts. Summary of the Utility Model

[0003] Based on the fact that it is difficult to accurately move a single optical engine by manually adjusting bolts during binocular image synthesis of existing AR glasses, it is necessary to provide a binocular optical engine assembly and an AR glasses.

[0004] A binocular optical engine assembly, comprising:

[0005] A binocular optical engine bracket, the binocular optical engine bracket includes a bracket part having a plurality of jacks and positioning columns fixed to the bracket part;

[0006] A pair of optical engine modules, the optical engine module is provided with bolt holes corresponding to the jacks and a fitting part that is in clearance fit with the positioning part;

[0007] Adjusting bolts, the adjusting bolts are movably inserted through the jacks and are in threaded fit with the bolt holes to mount the optical engine module on the bracket part; and

[0008] Elastic members, the elastic members are located between the bracket part and the optical engine module, and the opposite sides of the elastic members are respectively abutted against the bracket part and the optical engine module.

[0009] With such a setting, the position matching between the positioning part and the mating part realizes the pre-positioning between the optical engine module and the bracket part, ensuring that the two are fastened by adjusting bolts subsequently. The clearance fit between the positioning part and the mating part can not only avoid interference between the positioning part and the mating part when moving a single optical engine module, but also reduce the relative misalignment between the optical engine module and the bracket part, further restricting the adjustment range of the adjusting bolts, which is beneficial to improving the efficiency of image synthesis adjustment; during assembly and binocular image synthesis, the elastic part is used to expand the space between the optical engine module and the bracket part. Restricted by the adjusting bolts, the optical engine module and the bracket part will not separate further. The adjusting bolts and the elastic part restrict each other, enabling the optical engine module and the bracket part to accurately reach the preset position. When it is necessary to adjust a single optical engine to ensure the image synthesis quality, the optical engine module can be moved precisely and efficiently to ensure the binocular image synthesis quality.

[0010] In one embodiment, the positioning part is provided with a positioning post, the mating part is provided with a positioning hole, and the positioning post is inserted into the positioning hole.

[0011] With such a setting, the positioning hole forms sufficient radial limitation on the positioning post, and the structure is simple, which is convenient for design and production.

[0012] In one embodiment, the positioning post has a connecting end connected to the bracket part and a plugging end inserted into the positioning hole, and the diameter of the positioning post gradually increases from the plugging end to the connecting end.

[0013] With such a setting, when one side of the optical engine module deviates from the bracket part, it is beneficial to reduce the interference generated between the connecting end of the positioning post and the bracket part.

[0014] In one embodiment, the diameter of the connecting end is larger than the diameter of the positioning hole.

[0015] With such a setting, when AA image synthesis is not required, the connecting end can abut against the orifice of the positioning hole of the bracket part, which is beneficial to increasing the connection accuracy between the bracket part and the optical engine module.

[0016] In one embodiment, the ratio of the diameter of the plugging end to the aperture diameter of the positioning hole is greater than or equal to 0.8 and less than 1.

[0017] With such a setting, within this range, it can not only give full play to the anti-misalignment function realized by the cooperation between the positioning post and the positioning hole, but also avoid the situation of position interference between the positioning post and the bracket part caused by the deflection of the optical engine module.

[0018] In one embodiment, the optical engine module includes an optical engine main body, a positioning cylinder fixed to the optical engine main body and providing the positioning hole, and a threaded cylinder fixed to the optical engine main body and providing the bolt hole.

[0019] With such a setting, the threaded cylinder not only provides bolt holes for cooperating with the adjusting bolts, but also can support the bracket part and provide an installation space for the arrangement of the elastic member.

[0020] In one embodiment, the optical engine module further includes a support table fixedly provided on one side of the optical engine body facing the bracket part, and two opposite sides of the elastic member respectively abut against the support table and the bracket part.

[0021] With such a setting, due to the setting of the threaded cylinder, the gap between the bracket part and the optical engine module is increased, and the setting of the support table provides an installation position for the elastic member. At the same time, since the distance between the support table and the bracket part is small, the selection of the elastic member is rich, and there is no need to customize elastic members with large length and rigidity, which is beneficial to reducing production costs.

[0022] In one embodiment, the elastic member is a foam.

[0023] With such a setting, the foam abuts tightly against the support table and the bracket part and rebounds in time, and can form a stable abutting force between the support table and the bracket part to ensure the image combining accuracy.

[0024] In one embodiment, the bracket part includes a bracket plate providing the jack and an abutting ring extending towards the threaded cylinder around the jack, the abutting ring abuts against the threaded cylinder, and the outer diameter of the abutting ring is smaller than the outer diameter of the threaded cylinder to form a filling groove for filling the curing glue with the threaded cylinder and the bracket plate.

[0025] With such a setting, the contact area between the filling groove formed by the abutting ring, the bracket part and the threaded cylinder and the curing glue is large, which improves the connection strength between the binocular optical engine bracket, the optical engine module and the curing glue, and ensures that the image combining accuracy will not change.

[0026] In one embodiment, each optical engine module corresponds to two groups of the jacks, the number of each group of the jacks is at least two, each optical engine module corresponds to two positioning holes, the bolt holes are also two groups corresponding to the jacks, and the number of each group of the bolt holes is the same as the number of each group of the jacks, and the positioning holes are located between two of the bolt holes in each group of the bolt holes.

[0027] With such a setting, arranging the positioning holes between two bolt holes not only saves the layout space of the binocular optical engine bracket, but also can effectively limit the optical engine module and the bracket part by the cooperation of the positioning column and the positioning hole no matter which adjusting bolt is loosened during image combining adjustment.

[0028] This application also provides an AR glasses, including:

[0029] A protective shell; and

[0030] As described above, the binocular optical machine assembly is installed in the protective case.

[0031] With such an arrangement, since the binocular optical machine assembly provided by this proposal has better binocular image synthesis accuracy, the immersion feeling of the user during wearing is improved. Brief Description of the Drawings

[0041] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. A lot of specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0042] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0044] In the present utility model, unless otherwise clearly specified and defined, the terms "mounted", "connected", "connected to", "fixed" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0045] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0047] In an AR glasses, there is a way of binocular image synthesis. First, the image synthesis of a single BB (BirdBath) optical engine is completed (meeting the two indicators of MTF and boresight), and then the single BB optical engine unit is assembled onto the binocular bracket. MTF (modulation transfer function) combines two indicators of resolution and contrast, representing the ability of the imaging system to convert resolution into contrast. Boresight represents the visual axis difference, including the errors of the two images on the image side and the eyepiece side in three dimensions of horizontal, vertical and rotation. The existing BB optical engine is usually directly positioned and fixed by bolts when installed on the binocular optical engine bracket. Due to the assembly error existing in the bolt fastening itself, the binocular image synthesis accuracy of the AR glasses is not high. The existing AA image synthesis can only improve the quality of single-eye image synthesis. When it is necessary to adjust a single optical engine to ensure the quality of binocular image synthesis, it is difficult to accurately move a single optical engine by manually adjusting the bolts.

[0048] Based on this, it is necessary to provide a binocular optical engine assembly and an AR glasses with higher assembly accuracy and higher binocular image synthesis accuracy.

[0049] Please refer to Figures 1 to 3 , Figure 1 , which is a schematic structural diagram of a binocular optical engine assembly in an embodiment of the present utility model. Figure 2 is Figure 1 a schematic plan view of the binocular optical engine assembly shown. Figure 3 is Figure 2 a cross-sectional view of the binocular optical engine assembly shown at A-A.

[0050] The binocular motor assembly provided in the present application includes a binocular motor bracket 10, a pair of optical machine modules 20, a plurality of adjustment bolts 30 and a plurality of elastic members 40. The binocular motor bracket 10 includes a bracket portion 11 having a plurality of insertion holes 101 and a positioning portion 12 fixed to the bracket portion 11. The optical machine module 20 is provided with bolt holes 201 corresponding to the insertion holes 101 and a mating portion 202 that is clearance-matched with the positioning portion 12. The adjustment bolts 30 can be movably inserted into the insertion holes 101 and threadedly matched with the bolt holes 201 to install the optical machine module 20 on the bracket portion 11. It is worth noting that the diameter of the adjustment bolts 30 is smaller than the diameter of the insertion holes 101 to avoid interference between the adjustment bolts 30 and the binocular motor bracket 10 when adjusting. The elastic member 40 is located between the bracket portion 11 and the optical machine module 20, and the two opposite sides of the elastic member 40 are respectively abutted against the bracket portion 11 and the optical machine module 20. In this embodiment, the positioning portion 12 is provided with a positioning column 121, and the matching portion 202 is provided with a positioning hole 2021. Such a structure is simple and convenient for mold production. It can be understood that in other embodiments, the positioning portion 12 can also be provided with the positioning hole 2021 in the above embodiment, and the matching portion 202 can also be provided with the positioning column 121 in the above embodiment. As long as clearance fit can be achieved, structures of other shapes are not further limited here. The position coordination of the positioning post 121 and the positioning hole 2021 realizes the pre-positioning between the optical machine module 20 and the bracket part 11, ensuring that the two are subsequently tightened by the adjusting bolt 30. The restriction of the positioning hole 2021 on the positioning post 121 not only reduces the relative displacement between the optical machine module 20 and the binocular lens bracket 10, but also further limits the adjustment range of the adjusting bolt 30, which is conducive to improving the efficiency of the combined image adjustment; during the assembly and binocular combined image process, the elastic member 40 is used to open the optical machine module 20 and the bracket part 11. Restricted by the adjusting bolt 30, the optical machine module 20 and the bracket part 11 will not be further separated. The adjusting bolt 30 and the elastic member 40 check and balance each other, so that the optical machine module 20 and the bracket part 11 can accurately reach the preset position. When it is necessary to adjust a single optical machine to ensure the quality of combined image, the optical machine module 20 can be moved accurately and efficiently to ensure the quality of binocular combined image.

[0051] Further, for the convenience of demolding during the production of the binocular optical machine bracket 10, in an embodiment provided in the present application, the positioning post 121 has a connection end 1211 connected to the bracket portion 11 and a plugging end 1212 inserted into the positioning hole 2021, and the diameter of the positioning post 121 gradually increases from the plugging end 1212 to the connection end 1211. When one side of the optical machine module 20 deviates from the bracket portion 11, this is also beneficial for reducing the interference generated between the connection end 1211 of the positioning post 121 and the bracket portion 11. Optionally, in an embodiment provided in the present application, the diameter of the connection end 1211 is greater than the diameter of the positioning hole 2021. When AA imaging is not required, the connection end 1211 can abut against the orifice of the positioning hole 2021 of the bracket portion 11, which is beneficial for increasing the connection accuracy between the bracket portion 11 and the optical machine module 20. It can be understood that in other embodiments, the positioning hole 2021 can also be a variable-diameter hole, that is, the aperture of the positioning hole 2021 gradually increases from the orifice inward, which can also provide a clearance for the binocular imaging adjustment of the optical machine module 20 and avoid position interference between the positioning post 121 and the optical machine module 20. It can be understood that in other embodiments, the diameter of the positioning post 121 can also remain unchanged along the axial direction, as long as there is a clearance fit between the positioning post 121 and the positioning hole 2021.

[0052] Specifically, when the imaging adjustment is performed on a single optical machine and the optical machine module 20 deflects, the positioning post 121 is gradually withdrawn from the positioning hole 2021 and deflects simultaneously with the deflection of the optical machine module 20. There are the following three working conditions between the positioning post 121 and the positioning hole 2021: In the first working condition, the side wall of the positioning post 121 always abuts against the side of the positioning hole 2021 near the loosened adjusting bolt 30. Therefore, during the binocular imaging process, the imaging position of the cross on the test chart corresponds to the abutting point on the positioning post 121, so as to accurately move the optical machine module 20 with a high adjustment efficiency; In the second working condition, the positioning post 121 always abuts against the side of the positioning hole 2021 far from the loosened adjusting bolt 30. Therefore, during the binocular imaging process, the imaging position of the cross on the test chart also corresponds to the abutting point on the positioning post 121, so as to accurately move the optical machine module 20 with a high adjustment efficiency; In the third working condition, there is always a gap between the positioning post 121 and the hole wall of the positioning hole 2021. Even so, the positioning hole 2021 can still limit the movement of the positioning post 121 to prevent a large dislocation of the relative position between the bracket portion 11 and the optical machine module 20 with the loosening of the adjusting bolt 30; In addition, in the third working condition, the positioning post 121 can still be made to abut against the hole wall of the positioning hole 2021 by adjusting other adjusting bolts 30, so as to achieve the accurate movement of the optical machine module 20.

[0053] Please refer to Figure 4 ,Figure 4 The Figure 3 partial enlarged view of the structure shown at X. Optionally, in an embodiment provided by the present application, the ratio of the diameter of the insertion end 1212 to the aperture diameter of the positioning hole 2021 is greater than or equal to 0.8 and less than 1. Within this range, the anti-displacement function achieved by the cooperation of the positioning post 121 and the positioning hole 2021 can be fully exerted, and the situation of position interference between the positioning post 121 and the bracket portion 11 caused by the deflection of the optical engine module 20 can be avoided and reduced. Optionally, when the above ratio range is satisfied, the gap between the outer peripheral wall of the positioning post 121 and the hole wall of the positioning hole 2021 is less than or equal to 0.5 mm, which is beneficial to further improving the anti-position interference effect. Exemplarily, in an embodiment provided by the present application, the outer diameter of the insertion end 1212 is 1.90 mm, and the aperture diameter of the positioning hole 2021 is 2.00 mm. At this time, the radial movement amount of the positioning post 121 in the positioning hole 2021 is ±0.05 mm.

[0054] Please refer to Figure 5 and Figure 6 , Figure 5 is Figure 2 the sectional view of the binocular optical engine assembly shown in the B-B direction, Figure 6 is Figure 5 the structural schematic diagram of the optical engine module 20 in

[0055] Further, please refer to Figure 5 and Figure 7 , Figure 7 is Figure 5Schematic diagram of the structure of the middle support part 11. Optionally, in an embodiment provided by the present application, the optical engine module 20 further includes a support platform 24, which is fixedly arranged on the side of the optical engine main body 21 facing the support part 11. The two opposite sides of the elastic member 40 are respectively abutted against the support platform 24 and the support part 11. Due to the arrangement of the threaded cylinder 23, the gap between the support part 11 and the optical engine module 20 is increased, and the arrangement of the support platform 24 provides an installation position for the elastic member 40. At the same time, since the distance between the support platform 24 and the support part 11 is small, the selection of the elastic member 40 is rich, and there is no need to customize the elastic member 40 with large length and rigidity, which is beneficial to reducing the production cost. Optionally, in an embodiment provided by the present application, the elastic member 40 is a foam. The foam is in close contact with the support platform 24 and the support part 11, and rebounds in time, and can form a stable abutting force between the support platform 24 and the support part 11 to ensure the image synthesis accuracy. It can be understood that the elastic member 40 can also be other elastic objects such as a spring or a spring sheet. Optionally, in an embodiment provided by the present application, a reinforcing rib 25 is further arranged between the support platform 24 and the threaded cylinder 23 to increase the structural strength of the optical engine module 20 itself and ensure the accuracy of binocular image synthesis.

[0056] Please refer to Figure 4 and Figure 6 , Figure 6 is Figure 5Schematic diagram of the structure of the optical machine module 20. Optionally, in one embodiment provided in the present application, the bracket portion 11 includes a bracket plate 111 providing a socket 101 and an abutment ring 112 surrounding the socket 101 and extending toward the threaded barrel 23, the abutment ring 112 abuts against the threaded barrel 23, and the outer diameter of the abutment ring 112 is smaller than the outer diameter of the threaded barrel 23 to form a filling groove 50 for filling with curing glue with the threaded barrel 23 and the bracket plate 111. The contact area between the filling groove 50 formed by the abutment ring 112, the bracket portion 11 and the threaded barrel 23 and the curing glue is large, which improves the connection strength between the binocular optical machine bracket 10, the optical machine module 20 and the curing glue, and ensures that the image combination accuracy does not change. It is understandable that after the binocular image detection, in the qualified binocular camera assembly, the bracket part 11 and the optical machine module 20 are relatively fixed by curing glue. Therefore, in the present application, the role of the foam is mainly used for assembly and image adjustment. When the image accuracy of the optical machine module 20 itself is sufficient, one of the optical machine modules 20 is often locked. At this time, the optical machine module 20 does not need to be adjusted for binocular image adjustment and does not need to install elastic parts 40 such as foam, which also saves time for binocular image adjustment. When the curing glue solidifies, the foam can also be extracted, that is, the foam can be reused to save production costs. Optionally, in this embodiment provided in the present application, a sinking groove 113 is opened on the side of the bracket body away from the abutment ring 112, and multiple sockets 101 are all located in the sinking groove 113, and the enlarged head of the adjustment bolt 30 is also accommodated in the sinking groove 113 to reduce the height of the entire binocular camera assembly.

[0057] The image combination adjustment of the binocular eye assembly provided in this application can actually be applied to three situations:

[0058] In the first case, when the combination accuracy of the optical machine module 20 is high enough, that is, no binocular combination adjustment is required, the positioning column 121 and the positioning hole 2021 are used to pre-position the optical machine module 20 to the bracket 11. At this time, the optical machine module 20 and the bracket 11 are directly assembled into a combination product by locking and calibrating.

[0059] The second case is that it is necessary to adjust a single optical engine module 20 for binocular image synthesis. At this time, a single optical engine module 20 (such as the left eye) can be locked. There is no need to set an elastic member 40, that is, foam between the optical engine module 20 and the bracket portion 11. Or rather, if the elastic member 40 is set, the elastic member 40 can be compressed between the optical engine module 20 and the bracket portion 11 through the adjusting bolt 30 in a fixed gap, which will not affect the installation height of the optical engine module 20. Then lock the other optical engine module 20 (such as the right eye), and confirm whether the image synthesis meets the requirements. If not, loosen the adjusting bolt 30 corresponding to this optical engine module 20. During this process, the foam rebounds and cooperates with the limit of the adjusting bolt 30 to accurately move this optical engine module 20 (right eye). This movement actually includes a rotational component and a horizontal movement component. At this time, the clearance fit between the positioning post 121 and the positioning hole 2021 can limit this rotational component and horizontal movement component, thereby reducing the adjustment difficulty. If the image synthesis adjustment is qualified, then use glue to solidify the gap between the binocular optical machine bracket 10 and the optical engine module 20 to ensure that the image synthesis of the finished binocular optical machine component will not change again;

[0060] The third case is that the adjustment of a single optical engine module 20 cannot meet the image synthesis requirements. At this time, both optical engine modules 20 can be adjusted, so as to increase the image synthesis adjustment amount and ensure that the image synthesis is qualified. Please refer to Figure 4 and Figure 5 . Specifically, in an embodiment provided by the present application, each of the optical engine modules 20 corresponds to two groups of the jacks 101. The number of each group of the jacks 101 is at least two. Each optical engine module 20 corresponds to two of the positioning holes 2021. The bolt holes 201 are also two groups corresponding to the jacks 101, and the number of each group of the bolt holes 201 is the same as the number of each group of the jacks 101. The positioning hole 2021 is located between the two bolt holes 201 of each group of the bolt holes 201. In this embodiment, by arranging the positioning hole 2021 between the two bolt holes 201, not only the layout space of the binocular optical machine bracket 10 is saved, but also when adjusting the image synthesis, no matter which adjusting bolt 30 is loosened, the cooperation between the positioning post 121 and the positioning hole 2021 can effectively limit the optical engine module 20 and the bracket portion 11. Specifically, in order to increase the structural strength, the positioning cylinder 22 for providing the positioning hole 2021 and the threaded cylinder 23 for providing the bolt holes 201 are connected in sequence to form an integral structure on one side of the optical engine module 20.

[0061] The present application also provides an AR glasses, including a protective shell and the binocular optical machine component as described above. The binocular optical machine component is installed in the protective shell. Since the binocular optical machine component provided by this proposal has better binocular image synthesis accuracy, it improves the immersion feeling of the user during wearing.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
