Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and more specifically, to a head-mounted device and a method for adjusting the interpupillary distance of the same. Background Technology

[0002] With the development of technology, augmented reality (AR) headsets, virtual reality (VR) headsets, and mixed reality (MRP) headsets are increasingly being used in daily life and work. When wearing these headsets, due to differences in interpupillary distance among users, the binocular images may not overlap, resulting in blurred images or discrepancies between virtual and real images. To accommodate users with different interpupillary distances, headsets can be equipped with interpupillary distance adjustment devices to achieve automatic or manual adjustment of the two display modules.

[0003] Common interpupillary distance adjustment devices include sliding rails, with two display modules mounted on the rails and able to slide along them under the drive of a driving device or manually. When the two display modules move towards each other simultaneously on the sliding rails, the corresponding interpupillary distance decreases; when the two wiring harness modules move in opposite directions simultaneously on the sliding rails, the corresponding interpupillary distance increases.

[0004] Because a design gap needs to be reserved between the sliding guide rail and the display module to ensure smooth sliding, and because machining tolerances are unavoidable in each component, the movement gap will lead to the problem of tolerance accumulation. As a result, when adjusting, the display module is prone to displacement in the horizontal, vertical, and relative rotational directions exceeding the target set value, which will cause problems such as blurred images or deviations between virtual images and real objects in the binocular composite image. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a head-mounted device and a method for adjusting the interpupillary distance of the same device, which can effectively solve the problem of blurred images or deviation between virtual images and real objects in binocular composite images after interpupillary distance adjustment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A head-mounted device, comprising:

[0008] case;

[0009] A sliding guide rail is provided on the housing;

[0010] The display module includes a display body and a mounting body connected to the display body. The mounting body is slidably disposed on the sliding guide rail along a first direction, and the mounting body has a positioning part.

[0011] A corrective member is movably disposed in the housing. The corrective member has a limiting part for contacting and positioning with different positions of the positioning part. When the corrective member is locked in a state of cooperating with the display module, the limiting part contacts the positioning part to realize the positioning of the display module. When the corrective member is separated from the display module, the positioning function is released.

[0012] Optionally, in the head-mounted device described above, when the positioning part is in contact with the limiting part, the display module is positioned in both the second direction perpendicular to the first direction and the rotational direction around the first direction.

[0013] Optionally, in the above-mentioned head-mounted device, the positioning part includes a first positioning surface and a second positioning surface, wherein the first positioning surface and the second positioning surface have different orientations and / or shapes, and the limiting part includes a first limiting surface that mates with the first positioning surface and a second limiting surface that mates with the second positioning surface.

[0014] Optionally, in the above-mentioned head-mounted device, both the first positioning surface and the second positioning surface are planes, and the first positioning surface intersects with the second positioning surface, or the plane containing the first positioning surface intersects with the plane containing the second positioning surface;

[0015] And / or,

[0016] Both the first limiting surface and the second limiting surface are planes, and the first limiting surface intersects with the second limiting surface, or the plane containing the first limiting surface intersects with the plane containing the second limiting surface.

[0017] Optionally, in the above-mentioned head-mounted device, the mounting part is provided with a strip groove, the cross-section of the strip groove is at least partially V-shaped, and one side of the V-shape is the first positioning surface, and the other side is the second positioning surface.

[0018] Optionally, in the above-mentioned head-mounted device, the first limiting surface is perpendicular to the direction of movement of the corrective element.

[0019] Optionally, in the above-mentioned head-mounted device, the correction component is detachably connected to the housing, and when the correction component is connected to the housing, the correction component cooperates with the display module.

[0020] Optionally, in the above-mentioned head-mounted device, the housing is provided with a mounting hole, one of the housing and the correction component is provided with a buckle, and the other is provided with a slot, and the correction component can be disposed in the mounting hole and the buckle and the slot can be engaged.

[0021] Optionally, in the above-mentioned head-mounted device, the correction component is slidably disposed on the housing, and when the correction component slides and locks in the first position, the correction component cooperates with the display module; when the correction component slides and locks in the second position, the correction component separates from the display module.

[0022] The head-mounted device provided by this invention includes a housing, a sliding guide rail, a display module, and an adjustment component. The sliding guide rail is disposed within the housing; the display module includes a display body and a mounting body connected to the display body, the mounting body being disposed on the sliding guide rail and capable of reciprocating along a first direction, and the mounting body having a positioning part; the adjustment component is movably disposed within the housing, and the adjustment component has a limiting part for contacting and positioning with the positioning part at different positions. When the adjustment component is locked in a state of engagement with the display module, the limiting part contacts the positioning part to achieve positioning of the display module; when the adjustment component is separated from the display module, the positioning effect is released.

[0023] The head-mounted device provided by this invention, by setting up an correction component, locks the correction component in a state that cooperates with the display module during the binocular fusion debugging phase of the head-mounted device. Through the positioning action of the limiting part on the correction component and the positioning part on the display module, the offset caused by accumulated tolerances is corrected, allowing the image to complete binocular fusion correction according to the set values. During the use of the head-mounted device, when it is necessary to adjust the displacement of the display module to suit users with different pupil distances, the correction component can move to separate from the display module, thus not creating resistance to the movement of the display module. When the display module moves to the preset position, locking the correction component in cooperation with the display module, the limiting part on the correction component and the positioning part on the display module achieve positioning, thereby correcting the offset caused by accumulated tolerances between the display module and the sliding guide rail, allowing the image to complete binocular fusion correction according to the set values. Through correction, the image presented after the pupil distance of the display module is adjusted is consistent with the display effect after binocular fusion correction, reducing or even eliminating the risk of blurred binocular synthesized images or deviations between virtual images and real objects caused by the displacement of the display module exceeding the target set value during adjustment. Therefore, the head-mounted device provided in this application can provide more stable images and improve the user experience.

[0024] This invention also provides the following technical solutions:

[0025] A method for adjusting the interpupillary distance of a head-mounted device includes:

[0026] Release the positioning function of the display module;

[0027] Move the display module to a preset position along the first direction;

[0028] The display module is repositioned after being moved, and the repositioning is consistent with the repositioning maintained during the binocular fusion debugging of the head-mounted device.

[0029] The interpupillary distance adjustment method for head-mounted devices provided by this invention positions the display module during the binocular fusion debugging stage to correct the offset caused by accumulated tolerances, ensuring the image is fused according to the set values. During use, when adjusting the display module's displacement to suit users with different interpupillary distances, the positioning of the display module is first released, allowing it to move along a first direction with low resistance. After the display module reaches the preset position, it is repositioned to correct the offset caused by accumulated tolerances between the display module and the sliding guide rail, ensuring the image is fused according to the set values. This correction ensures the image displayed after interpupillary distance adjustment is consistent with the binocular fusion correction, reducing or even eliminating the risk of blurred images or discrepancies between virtual and real images caused by the display module's displacement exceeding the target setting during adjustment. Therefore, the head-mounted device provided by this application provides more stable images and improves the user experience. Attached Figure Description

[0041] This invention discloses a head-mounted device and its interpupillary distance adjustment method to reduce or even eliminate image blurring or virtual image deviation from the real image in binocular synthesis after adjustment, thereby improving the stability of display quality and enhancing user experience.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The head-mounted device provided in this application includes a main body for providing display functions. The main body includes two display modules and an interpupillary distance adjustment structure for adjusting the distance between the two display modules, accommodating users with different interpupillary distances and improving user experience. It is understood that the interpupillary distance adjustment structure can achieve interpupillary distance adjustment by moving a single display module closer to or further away from the other display module (i.e., one display module is fixed and the other is adjustable), or by adjusting the movement of the two display modules towards or away from each other (i.e., both display modules are adjustable). The interpupillary distance adjustment structure includes a sliding guide rail, with the display modules slidingly engaged with the guide rail. The movement of the display modules can be driven by a drive component or manually. Specifically, the head-mounted device can be equipped with a motor, which is connected to the display modules via a transmission structure such as a lead screw to drive the display modules to move linearly, and the motor controls the direction and amount of movement of the display modules. Alternatively, the head-mounted device can also be equipped with a telescopic cylinder such as a pneumatic cylinder to drive the display modules to move linearly. Alternatively, the head-mounted device can be equipped with an operating mechanism such as a lever connected to the display module, allowing the user to manually adjust the position of the display module. Of course, depending on the needs, the head-mounted device can also be equipped with a locking structure to lock the display module at different positions within its sliding stroke, or the locking of the display module can be achieved through the drive component itself. At least one sliding guide rail that cooperates with the display module can be provided as needed. Figure 1In this configuration, two sliding guide rails 200 are provided to cooperate with the same display module 300, and the display module 300 slides along the two sliding guide rails 200. By providing at least two sliding guide rails, the sliding guide rails cooperate to achieve high-precision positioning of the display module, thereby reducing tolerances and improving the movement accuracy of the display module.

[0044] In this application, a corrective component is added to correct the accumulated tolerance between the display module and the sliding guide rail, ensuring the positional accuracy of the adjustment module while avoiding increasing the resistance during adjustment. Through the positioning action of the corrective component after the display module is adjusted to its correct position, the accumulated tolerance of the display module is corrected, thereby reducing or even eliminating image blurring or discrepancies between virtual and solid images that occur after adjustment. The following embodiments mainly describe the cooperation between the corrective component and the display module, as well as the assembly method of the corrective component.

[0045] In one specific embodiment, please refer to Figures 1-2The head-mounted device provided in this application includes a housing 100, a sliding rail 200, a display module 300, and an adjustment member 400. The sliding rail 200 is disposed on the housing 100, and the number of sliding rails 200 can be set as needed. The display module 300 includes a display body 310 and a mounting body 320 connected to the display body 310. The mounting body 320 is slidably disposed on the sliding rail 200 along a first direction, that is, the mounting body 320 cooperates with the sliding rail 200 to reciprocate along the first direction. The mounting body 320 has a positioning part 330 for cooperating with the display module 300 to position the display module 300. The adjustment member 400 is movably disposed on the housing 100, and thus the adjustment member 400 has different engagement states relative to the housing 100, including being installed on or detached from the housing 100, and also including being slidably or rotatably connected to the housing 100, thereby being able to be in different positions relative to the housing 100. Of course, one engagement state of the corrective member 400 relative to the housing 100 should be a state in which the corrective member 400 is locked in engagement with the display module 300. Specifically, the locking of the corrective member 400 can be achieved by engaging with either the housing 100 or the display module 300. The corrective member 400 has a limiting portion 410 for contacting and positioning with the positioning portion 330 at different positions. When the corrective member 400 is locked in engagement with the display module 300, the limiting portion 410 contacts the positioning portion 330 to achieve positioning of the display module 300. When the corrective member 400 is separated from the display module 300, the positioning effect is released. In other words, when the display module 300 slides to different positions and the corrective member 400 is locked in engagement with the display module 300 at different positions, the limiting portion 410 contacts the positioning portion 330 at different positions to position the display module 300. That is, the corrective member 400 can contact and position the corresponding position of the positioning part 330 when the display module 300 moves to different positions along the first direction. The different positions of the positioning part 330 can be continuous or discontinuous. For example, if the positioning part 330 extends along the first direction, the display module 300 can be positioned by the corrective member 400 when adjusted in the first direction. When the positioning part 330 includes multiple spaced sub-positioning parts 330, the display module 300 can be positioned by the corrective member 400 when it is intermittently adjusted in the first direction until the sub-positioning part 330 corresponds to the corrective member 400. Since the posture of the corrective member 400 in the locked state is determined by its installation method, even if the display module 300 deviates under the above-mentioned contact positioning action, it will be reset to the posture determined by the above-mentioned end positioning action due to the above-mentioned positioning action.

[0046] Using the head-mounted device provided by the present invention, during the binocular fusion debugging stage, the correction component 400 is locked in a state that cooperates with the display module 300. Through the positioning effect of the limiting part 410 on the correction component 400 and the positioning part 330 on the display module 300, the offset caused by the accumulated tolerance is corrected, so that the image completes the binocular fusion correction according to the set value.

[0047] After binocular fusion debugging is completed, during the use of the head-mounted device, when it is necessary to adjust the displacement of the display module 300 to suit users with different pupil distances, the correction element 400 can be moved to separate from the display module 300, thus not creating resistance to the movement of the display module 300. Then, the position of the display module 300 in the first direction is adjusted. When the display module 300 moves to the preset position, the correction element 400 is locked in cooperation with the display module 300. The limiting part 410 on the correction element 400 and the positioning part 330 on the display module 300 are positioned, thereby correcting the offset caused by the cumulative tolerance between the display module 300 and the sliding guide rail 200, so that the image completes the binocular fusion correction according to the set value.

[0048] In summary, the head-mounted device provided in this application, after the interpupillary distance adjustment function is activated and matched to the user's eyeballs, adjusts the corrector 400 to a locked state in conjunction with the display module 300. The display module 300 then corrects the interpupillary distance to ensure that the image presented after the adjustment is consistent with the display effect after binocular fusion correction. This reduces or even eliminates the risk of blurred binocular synthesized images or discrepancies between virtual images and real objects caused by the display module 300's displacement exceeding the target setting value during adjustment. Therefore, the head-mounted device provided in this application can provide more stable images and improve the user experience.

[0049] In some embodiments, when the positioning part 330 is in contact with the limiting part 410, the display module 300 is positioned in at least one of the second direction and the rotational direction about the first direction. The first and second directions are perpendicular. When the display module 300 moves along the first direction, due to accumulated tolerances, it may shift in the second direction or deflect around the first direction. The cooperation between the positioning part 330 and the limiting part 410 achieves positioning of the display module 300 in at least one of the second direction and the rotational direction about the first direction, reducing or even eliminating the shift of the display module 300 in the corresponding direction, thereby improving the binocular fusion effect of the image. Depending on the needs, when the positioning part 330 is in contact with the limiting part 410, the display module 300 may also be positioned in a third direction, where the first, second, and third directions are perpendicular to each other. Specifically, when the positioning part 330 is in contact with the limiting part 410, the display module 300 is positioned in the second direction, the third direction, and the rotational direction about the first direction. When the head-mounted device is in use, the second direction can be vertical, and the third direction can be horizontal. Through the initial binocular fusion adjustment stage, the corrector 400 achieves a clear and accurate binocular fusion image by correcting the horizontal, vertical, and relative rotational directions. Simultaneously, during product use, after interpupillary distance adjustment, the corrector 400 is added to correct the cumulative effect of tolerances on binocular fusion imaging, achieving the same display effect as in the binocular fusion stage. The specific structure of the corrector 400 can be customized according to different product forms. Its core design principle is to limit the optical module in the aforementioned directions, ensuring that the image displayed after interpupillary distance adjustment is consistent with the image in the binocular fusion adjustment state, thereby achieving the ideal display effect.

[0050] In some embodiments, please refer to Figure 3 and Figure 4 The positioning part 330 includes a first positioning surface 331 and a second positioning surface 332. The first positioning surface 331 and the second positioning surface 332 have different orientations and / or shapes. The limiting part 410 includes a first limiting surface 411 that mates with the first positioning surface 331 and a second limiting surface 412 that mates with the second positioning surface 332. By having the first positioning surface 331 mate with the first limiting surface 411 and the second positioning surface 332 mate with the second limiting surface 412, the structure is simple, easy to manufacture, and the positioning is reliable. In addition, the first positioning surface 331 and the second positioning surface 332 have different orientations and / or shapes, and their combination can better position the spatial posture of the display module 300.

[0051] In some embodiments, both the first positioning surface 331 and the second positioning surface 332 are planes. The first positioning surface 331 intersects with the second positioning surface 332, or the plane containing the first positioning surface 331 intersects with the plane containing the second positioning surface 332. It is understood that the first limiting surface 411 mates with the first positioning surface, and it can specifically be a plane, or it can be other curved surfaces capable of forming multi-point or multi-line contact with the first positioning surface 331. Correspondingly, the second limiting surface 412 mates with the second positioning surface 332, and it can specifically be a plane, or it can be other curved surfaces capable of forming multi-point or multi-line contact with the second positioning surface 332. The first positioning surface 331 and the second positioning surface 332 adopt a planar design, which is simple in structure and facilitates continuous positioning and mating with the straightening member 400 within a certain range. Conversely, the first limiting surface 411 and the second limiting surface 412 can also be set to be planes, with the first limiting surface 411 intersecting the second limiting surface 412, or the plane containing the first limiting surface 411 intersecting the plane containing the second limiting surface 412. At least one of the positioning surface (first positioning surface 331 and second positioning surface 332) and the limiting surface (first limiting surface 411 and second limiting surface 412) is a plane. Planar contact positioning has high accuracy, simple structure, and is easy to process.

[0052] In some embodiments, the first positioning surface 331 and the second positioning surface 332 are both planar and extend along a first direction. This ensures that the display module 300 can be positioned by the corrector 400 at various consecutive positions adjusted in the first direction, guaranteeing high-precision continuous adjustability of the display module 300. Specifically, the lengths of the first positioning surface 331 and the second positioning surface 332 are not less than the maximum travel distance of the display module 300. This allows the display module 300 to cooperate with the corrector 400 throughout its adjustment travel distance, enabling it to be positioned by the corrector 400 at various consecutive positions within the adjustment travel distance, thus achieving high-precision continuous adjustability of the display module 300 throughout its entire travel distance.

[0053] In some embodiments, the mounting part is provided with a strip groove, the cross-section of which is at least partially V-shaped, with one side of the V-shape being a first positioning surface 331 and the other side being a second positioning surface 332. It is understood that the included angle between the two sides of the V-shape can be set as needed, specifically not less than 90 degrees, to facilitate the assembly and movement of the straightening component 400. Utilizing the strip groove in conjunction with the straightening component 400, after the straightening component 400 is locked in place, the first positioning surface 331 contacts the first limiting surface 411, and the second positioning surface 332 contacts the second limiting surface 412. Because the posture of the straightening component 400 in its locked state is determined by its mounting method, even if the display module 300 deviates under the aforementioned contact positioning action, it will be reset to the determined posture of the first positioning surface 331 and the first limiting surface 411 contacting, and the second positioning surface 332 and the second limiting surface 412 contacting, due to the aforementioned positioning action. As configured above, the structure is simple and the positioning accuracy is high.

[0054] In some embodiments, the first limiting surface 411 is perpendicular to the direction of movement of the corrector 400. This arrangement facilitates assembly, and also improves the positioning stability of the first limiting surface 411 when the corrector 400 is locked. Specifically, the second limiting surface 412 is inclined to the direction of movement of the corrector 400, so that the positioning of the display module 300 can be gradually achieved during the movement of the corrector 400.

[0055] In some embodiments, the mounting body 320 includes end portions located at both ends and a middle portion connecting the two end portions. A V-shaped groove is provided in the middle portion. One side wall of the V-shaped groove is a first positioning surface 331, and a semi-circular groove is provided on the first positioning surface 331 to cooperate with the cylindrical sliding guide rail 200. The other side wall of the V-shaped groove is a second positioning surface 332. The two ends of the sliding guide rail 200 pass through the corresponding two end portions. The straightening member 400 is block-shaped, and the bottom surface of the straightening member 400 is... The first limiting surface 411 has a semi-circular groove for engaging with the sliding guide rail 200. The side of the corrector 400 that contacts the bottom surface is the second limiting surface 412. The corrector 400 has a slot 420 parallel to the first limiting surface 411 for engaging with the locking head on the housing 100. At least the portion of the corrector 400 forming the slot 420 is made of elastic material, so that the corrector 400 can engage or contact with the housing 100 through elastic deformation. With the above configuration, the positioning and engagement structure is simple and accurate. The corrector 400 can engage with the sliding guide rail 200, and combined with the limiting effect of the sliding guide rail 200 on the corrector 400, the posture accuracy of the corrector 400 in the locked state is further guaranteed, thus making its positioning of the display module 300 more accurate.

[0056] In some embodiments, please refer to Figure 5The corrector 400 is detachably connected to the housing 100, and when connected to the housing 100, the corrector 400 engages with the display module 300. When it is necessary to adjust the displacement of the display module 300 to suit users with different interpupillary distances, the corrector 400 can be moved to separate from the display module 300, thus not hindering the movement of the display module 300. Then, the position of the display module 300 in the first direction is adjusted. After the display module 300 moves to the preset position, the corrector 400 is installed on the housing 100. The limiting part 410 on the corrector 400 and the positioning part 330 on the display module 300 are positioned, ensuring that the image presented after interpupillary distance adjustment is consistent with the display effect after binocular fusion correction. Taking the movement of two display modules 300 along the first direction as an example, a correction component 400 is set for each display module 300. Under the influence of the motion mechanism or manual adjustment, the two display modules 300 simultaneously reciprocate along the sliding guide rail 200. When they reach a certain position, the two correction components 400 are installed in place, achieving the correction and positioning of the optical module. In this state, binocular image fusion is performed, resulting in a good image fusion effect. After the entire device is assembled, when the user wears and uses the product, the two correction components 400 can be removed first. Under the influence of the motion mechanism or manual adjustment, the two display modules 300 are moved to the user's matching pupil position, and then the two correction components 400 are installed in place again. This ensures that the image presented is consistent with the image adjusted in the previous binocular fusion stage, achieving the correction purpose.

[0057] In some embodiments, the housing 100 is provided with a mounting hole 101. One of the housing 100 and the straightening member 400 is provided with a buckle, and the other is provided with a slot 420. The straightening member 400 can be disposed in the mounting hole 101 and the buckle and slot 420 can be engaged. The straightening member 400 is engaged with the housing 100, which is convenient for disassembly and assembly. In the state where the buckle and slot 420 are engaged, the straightening member 400 is reliably and stably locked on the housing 100, and the positioning of the display module 300 is achieved through the cooperation of the limiting part 410 and the positioning part 330. Specifically, the housing 100 includes a front housing 110 and a rear housing 120. A portion of the mounting hole 101 is provided in the front housing 110, and the other portion is provided in the rear housing 120.

[0058] In some embodiments, the corrective element 400 is slidably disposed on the housing 100. When the corrective element 400 slides and locks in a first position, it engages with the display module 300; when it slides and locks in a second position, it disengages from the display module 300. In other words, the corrective element 400 is slidably mounted, and by locking it at different positions along its sliding stroke, it switches between engaging with the display module 300 for positioning and disengaging from it. This configuration eliminates the need to disassemble the corrective element 400, preventing its loss. Specifically, the corrective element 400 can be a button; when pressed, it engages with the display module 300, and when released, it disengages. In other embodiments, the corrective element 400 can also be a knob.

[0059] This application also provides a method for adjusting the interpupillary distance of a head-mounted device. In one specific embodiment, the method includes the following steps:

[0060] S1: Release the positioning function of the display module 300;

[0061] S2: Move the display module 300 to the preset position along the first direction;

[0062] S3: Reposition the moved display module 300 to match the positioning maintained during binocular fusion debugging of the head-mounted device.

[0063] The interpupillary distance adjustment method provided by this invention is applicable to the aforementioned head-mounted device. During the binocular fusion debugging phase of the head-mounted device, the display module 300 is positioned. Specifically, the display module 300 can be positioned using the aforementioned corrector 400 to correct the offset caused by accumulated tolerances, ensuring the image completes binocular fusion correction according to the set values. After debugging, during subsequent use of the head-mounted device, when it is necessary to adjust the displacement of the display module 300 to suit users with different interpupillary distances, the positioning of the display module 300 is first released. Specifically, the positioning of the display module 300 by the corrector 400 is released, allowing the display module 300 to move along the first direction with lower resistance. Once the display module 300 has moved to the preset position, it is repositioned. Specifically, the display module 300 is repositioned again using the corrector 400, thereby correcting the offset caused by accumulated tolerances between the display module 300 and the sliding guide rail 200, ensuring the image completes binocular fusion correction according to the set values. By correcting the image displayed after the pupil distance of the display module 300 is adjusted to match the display effect after binocular fusion correction, the risk of blurred binocular synthesized images or deviations between virtual images and real objects caused by the displacement of the display module 300 exceeding the target setting value during adjustment is reduced or even eliminated. Therefore, the head-mounted device provided in this application can provide more stable images and improve the user experience.
