The lens module 351 is closer to the imaging body 33 than the lens module 352, so that the light emitted by the imaging body 33 and/or the ambient light are transmitted on the optical axis and sequentially penetrate the lens module 351 and the lens module 352, and then are emitted from the light outlet 3002 to the accommodating space 3001 and are injected into the human eyes. The ratchet 342 rotates relative to the main housing 341, so that the lens module 351 slides on the first sliding rail 3412 and the second sliding rail 3422, respectively. And the lens module 351 can slide in the extending direction of the first sliding rail 3412, so that the lens module 351 can slide in the extending direction of the second sliding rail 3422. Finally, the lens module 351 is moved in a direction approaching or separating from the lens module 352 in the optical axis direction, or in a direction approaching or separating from the imaging body 33 in the optical axis direction, adjusting the diopter of the lens 35.

The lens module 351 has diopter, and may be composed of one or more single lenses with diopter, and of course may also include other single lenses such as a flat mirror, a color mirror, etc., and may even further include various functional films such as an antireflection film, an electrochromic film, a photochromic film adhesive film, etc.

The lens module 351 is provided with a slider 3511. The slider 3511 is slidably connected to the first sliding rail 3412 and the second sliding rail 3422, respectively. In the case that the ratchet 342 rotates relative to the main housing 341, the lens module 351, for example, the slider 3511, can rotate around the rotation axis, so that the slider 3511 can slide on the first sliding rail 3412 and the second sliding rail 3422, respectively. Further, the slider 3511 is made slidable in the extending direction of the first slide rail 3412, and the slider 3511 is made slidable in the extending direction of the second slide rail 3422.

Since the first sliding rail 3412 may extend along the optical axis direction, or the angle between the extending direction of the first sliding rail 3412 and the optical axis direction may be greater than 0 °, the lens module 351, such as the slider 3511, may move along the optical axis direction.

Since the second slide rail 3422 may be spirally extended around the optical axis direction, the lens module 351 such as the slider 3511 may be moved in the optical axis direction.

In some embodiments, when the slider 3511 slides in the extending direction of the first sliding rail 3412, the slider can slide to a position abutting the limiting portion 3414, and is further limited, so as to stop the rotation of the ratchet 342 relative to the main housing 341.

In some embodiments, when the slider 3511 slides in the extending direction of the second slide rail 3422, the slider can slide to a position abutting the limiting portion 3424, and is further limited, so as to stop the ratchet 342 relative to the main housing 341.

In some embodiments, the slider 3511 can slide in the extending direction of the first sliding rail 3412 to a position abutting the limiting portion 3414, and can slide to a position abutting the limiting portion 3424.

The first sliding rail 3412 and the second sliding rail 3422 may not be limited thereto, and the first sliding rail 3412 may extend spirally around the optical axis direction, and the second sliding rail 3422 may extend along the optical axis direction, or the extending direction of the second sliding rail 3422 may have an angle greater than 0 ° with the optical axis direction.

In addition, the slider 3511 is mounted on the first sliding rail 3412 and the second sliding rail 3422 and is slidable on the first sliding rail 3412 and the second sliding rail 3422, respectively, one of the first sliding rail 3412 and the second sliding rail 3422 can limit the slider 3511 so that the slider 3511 can move in the optical axis direction, and the other of the first sliding rail 3412 and the second sliding rail 3422 can generate a force pushing the slider 3511 so that the slider 3511 moves in the optical axis direction under the guiding effect. Therefore, the arrangement and the extending direction of the first slide rail 3412 and the second slide rail 3422 are not limited as long as the first slide rail 3412 and the second slide rail 3422 are engaged to allow the slider 3511 to move in the optical axis direction.

The lens module 351 may not be limited to be slidably connected to the main housing 341 and the ratchet 342, and may be slidably connected to adjust the refractive power of the lens 35 by other means. One of the main housing 341 and the ratchet 342 may limit the slider 3511 such that the slider 3511 may move in the optical axis direction, and the other of the main housing 341 and the ratchet 342 may generate a force pushing the slider 3511 such that the slider 3511 moves in the optical axis direction under a guiding action.

Furthermore, the matching manner of the main housing 341 and the ratchet 342 can adjust the distance between the lens 35, such as the lens module 351, and the imaging main body 33, such as a device for display, so as to adjust the focal length, i.e. realize focusing.

The lens module 352 may have diopters, may be composed of one or more single lenses having diopters, and may include other single lenses such as flat mirrors, colored mirrors, etc., and may even include various functional films such as antireflection films, electrochromic films, photochromic film patches, etc.

The lens module 352 may have no diopter, may include other single lenses such as flat mirrors, colored mirrors, etc., and may even include various functional films such as antireflection films, electrochromic films, photochromic film stickers, etc.

The specific arrangement and structural composition of the lens module 352 can be designed according to technical schemes well known to those skilled in the art, and will not be described in detail.

The lens module 352 may be fixed on the main housing 341 and may be located in the accommodating space 3001. In some embodiments, the lens module 352 may be disposed at the light outlet 3002. In some embodiments, the lens module 352 may be disposed on the ratchet 342 instead of the main housing 341 as desired.

The structural design of the second imaging module 32 and the relationship with other structures are substantially identical to the structural design of the first imaging module 31 and the relationship with other structures, and the structural design of the second imaging module 32 and the relationship with other structures can refer to the structural design of the first imaging module 31 and the relationship with other structures, and will not be described in detail.

The diopter of the lens 35 in the second imaging module 32 and/or the distance between the imaging body 33 and, for example, a device for display can be adjusted with reference to the cooperation of the first imaging module 31 and the adjusting component 40, which will not be described in detail.

The matching manner of the lens 35 in the second imaging module 32 and the mounting board 20 can be adjusted by referring to the matching of the first imaging module 31 and the mounting board 20, so that the second imaging module 32, for example, the lens 35 slides to a side far from or near to the first imaging module 31, so as to adjust the pupil distance between the first imaging module 31 and the second imaging module 32, which is not described in detail.

Referring to fig. 2 and 3, the adjustment assembly 40 may include a first distance adjuster 41 drivingly coupled to the first imaging module 31, such as ratchet 342, and extending from the movable aperture 1003 in the mounting space 1001, and a second distance adjuster 42 drivingly coupled to the second imaging module 32, such as ratchet 342, and extending from the movable aperture 1003 in the mounting space 1001. The first distance adjusting member 41 may adjust the diopter of the lens 35 in the first imaging module 31, and/or adjust the distance between the lens 35 in the first imaging module 31 and the imaging body 33, e.g. a device for display, and/or adjust the distance between the lens module 351 and the lens module 352 in the first imaging module 31. The second distance adjuster 42 may adjust the refractive power of the lens 35 in the second imaging module 32 and/or adjust the distance between the lens 35 in the second imaging module 32 and the imaging subject 33, e.g., the device for display, and/or adjust the distance between the lens module 351 and the lens module 352 in the second imaging module 32.

It is understood that when the lens module 352 in the first imaging module 31 has diopter, the first distance adjuster 41 adjusts the distance between the lens module 351 in the first imaging module 31 and the lens module 352, i.e. adjusts the diopter of the lens 35 in the first imaging module 31. When the lens module 352 in the second imaging module 32 has diopter, the first distance adjuster 41 adjusts the distance between the lens module 351 in the second imaging module 32 and the lens module 352, that is, adjusts the diopter of the lens 35 in the second imaging module 32.

Referring to fig. 5, the first distance adjusting member 41 may include a connecting rod 411 rotatably connected to the imaging main body 33, such as the fitting 332, and a gear 412 disposed on the connecting rod 411 and drivingly connected to the first imaging module 31, such as the ratchet 342.

The connecting rod 411 can be clamped between the mounting base 3321 and the clamping plate 3322 to be clamped between the mounting base 3321 and the clamping plate 3322, thereby realizing rotational connection with the mounting base 3321. Of course, the connecting rod 411 may be rotatably connected to the imaging main body 33 by other means, such as a clamping connection, a screw connection, a bearing connection, etc., which will not be described in detail.

The connection rod 411 may protrude from the movable hole 1003 in the installation space 1001 so that the user rotates by touching.

In some embodiments, the connecting rod 411 may be fixedly connected directly to the imaging body 33, such as fitting 332, without being rotatably connected.

The gear 412 may be coaxially disposed with the connecting rod 411 such that the gear 412 rotates in synchronization with the connecting rod 411. The gear 412 may be in driving engagement with the ratchet 342, such as the ratchet 3425 teeth, by mating the gear and/or shaft, or may be in direct engagement with the ratchet 342, such as the ratchet 3425 teeth, for driving engagement. When the gear 412 rotates, the ratchet 342 is driven to rotate around the rotation axis, so as to adjust the diopter of the lens 35 in the first imaging module 31, and/or adjust the distance between the lens 35 in the first imaging module 31 and the imaging main body 33, such as a device for displaying, and/or adjust the distance between the lens module 351 and the lens module 352 in the first imaging module 31.

In some embodiments, a gear 412 is disposed at an end of the connecting rod 411.

In some embodiments, gear 412 may be omitted.

In some scenarios, a user may touch the first distance adjusting member 41, such as the connecting rod 411, and then twist the first distance adjusting member 41, such as the connecting rod 411, so that the first distance adjusting member 41, such as the gear 412, rotates, and then may rotate the ratchet 342 around the rotation axis under the condition that the gear engagement achieves transmission, to drive the lens module 351 to move toward a side close to or far from the lens module 352, so as to adjust the diopter of the lens 35 in the first imaging module 31, and/or adjust the distance between the lens 35 in the first imaging module 31 and the imaging body 33, such as a device for displaying, and/or adjust the distance between the lens module 351 in the first imaging module 31 and the lens module 352.

In some scenarios, a user may touch the first distance adjusting member 41, such as the connecting rod 411, and then toggle the first distance adjusting member 41, such as the connecting rod 411, and the first distance adjusting member 41, such as the connecting rod 411, may slide in the movable hole 1003 toward a side close to or far from the second imaging module 32, so that the first distance adjusting member 41, such as the connecting rod 411, is driven to the first imaging module 31, such as the imaging body 33, to realize the relative sliding of the first imaging module 31, such as the imaging body 33, and the mounting plate 20, so that the first imaging module 31, such as the imaging body 33, may slide toward a side close to or far from the second imaging module 32, so as to adjust the pupil distance between the first imaging module 31 and the second imaging module 32.

The structural design of the second distance adjusting member 42 and the relationship of the second distance adjusting member 32 and the second imaging module 32 are substantially identical to the structural design of the first distance adjusting member 41 and the relationship of the second distance adjusting member 42 and the second distance adjusting member can refer to the structural design of the first distance adjusting member 41 and the relationship of the second distance adjusting member and the second distance adjusting member are matched with each other, and are not repeated.

The connection rod 411 of the second distance adjusting member 42 may protrude from the movable hole 1003 in the installation space 1001 so that the user can touch and rotate.

When the gear 412 of the second distance adjusting member 42 rotates, the ratchet 342 of the second imaging module 32 is driven to rotate around the rotation axis, and the diopter of the lens 35 in the second imaging module 32 is adjusted, and/or the distance between the lens 35 in the second imaging module 32 and the imaging main body 33, such as a device for displaying, is adjusted, and/or the distance between the lens module 351 and the lens module 352 in the second imaging module 32 is adjusted.

In some scenarios, a user may touch the second distance adjusting member 42, such as the connecting rod 411, and then twist the second distance adjusting member 42, such as the connecting rod 411, such that the second distance adjusting member 42, such as the gear 412, rotates, which in turn may rotate the ratchet 342 in the second imaging module 32 about the rotation axis with the gear engaged to achieve the transmission, drive the lens module 351 in the second imaging module 32 to move toward a side closer to or farther from the lens module 352 to adjust the diopter of the lens 35 in the second imaging module 32, and/or adjust the distance between the lens 35 in the second imaging module 32 and the imaging body 33, such as the means for displaying, and/or adjust the distance between the lens module 351 in the second imaging module 32 and the lens module 352.

In some scenarios, a user may touch the second distance adjusting member 42, such as the connecting rod 411, and then toggle the second distance adjusting member 42, such as the connecting rod 411, may slide in the movable hole 1003 toward a side close to or away from the first imaging module 31, so that the second distance adjusting member 42, such as the connecting rod 411, is driven to the second imaging module 32, such as the imaging body 33, to realize the relative sliding of the second imaging module 32, such as the imaging body 33, and the mounting plate 20, so that the second imaging module 32, such as the imaging body 33, may slide toward a side close to or away from the first imaging module 31, so as to adjust the pupil distance between the first imaging module 31 and the second imaging module 32.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a structure of the display assembly 30 and the adjustment assembly 40 according to some embodiments of the present application. The adjustment assembly 40 may further include a synchronizing member 43 coupled to the first imaging module 31 and the second imaging module 32, respectively. The synchronization member 43 is configured to enable the first imaging module 31 and the second imaging module 32 to slide synchronously during pupil distance adjustment.

The synchronizing member 43 may include a slide lever 431 protruding from the movable hole 1003 in the installation space 1001, a first rotating lever 432 rotatably connected to the first imaging module 31 such as the imaging main body 33, the slide lever 431, and a second rotating lever 433 rotatably connected to the second imaging module 32 such as the imaging main body 33, the slide lever 431, respectively. The distance between the first rotating lever 432 and the two rotation axis lines of the first imaging module 31 such as the imaging main body 33 and the slide lever 431 respectively is equal to the distance between the second rotating lever 433 and the two rotation axis lines of the second imaging module 32 such as the imaging main body 33 and the slide lever 431 respectively, so that the first imaging module 31 and the second imaging module 32 slide synchronously at the time of pupil distance adjustment.

The slide bar 431 may be disposed between the first imaging module 31, e.g., the main housing 341, and the second imaging module 32, e.g., the main housing 341. The slide lever 431 is protruded from the movable hole 1003 in the installation space 1001 to be touched by the user, and thus to be pushed by the user.

In some cases, referring to fig. 6 and 7, fig. 7 is a schematic structural diagram of the display assembly 30 and the adjusting assembly 40 in the embodiment shown in fig. 6. In fig. 6, a user may touch the slide lever 431 and then push the slide lever 431 such that the slide lever 431 pushes the first and second rotating levers 432 and 433, and the first rotating lever 432 rotates about the rotation axis with respect to the slide lever 431 and the second rotating lever 433 rotates about the rotation axis with respect to the slide lever 431, and under spatial interference, the pushing of the slide lever 431 moves the first imaging module 31 such as the imaging main body 33 to a side away from the second imaging module 32 such as the imaging main body 33, and the second imaging module 32 such as the imaging main body 33 to a side away from the first imaging module 31 such as the imaging main body 33, thereby realizing the giving way to the first and second rotating levers 432 and 433, and during this, the first rotating lever 432 rotates about the rotation axis with respect to the first imaging module 31 such as the imaging main body 33 and the second rotating lever 433 rotates about the rotation axis with respect to the second imaging module 32 such as the imaging main body 33. Finally, the first imaging module 31 and the second imaging module 32 are slid synchronously by the slide lever 431 to the state shown in fig. 7 at the time of pupil distance adjustment.

In some scenarios, in fig. 7, a user may touch the slide bar 431 and then pull the slide bar 431 such that the slide bar 431 pulls the first and second rotating bars 432 and 433, rotation of the first rotating bar 432 about the rotation axis relative to the slide bar 431 and rotation of the second rotating bar 433 about the rotation axis relative to the slide bar 431 occurs, with spatial interference, pulling of the slide bar 431 moves the first imaging module 31, e.g., imaging body 33, to a side proximate to the second imaging module 32, e.g., imaging body 33, and the second imaging module 32, e.g., imaging body 33, to a side proximate to the first imaging module 31, e.g., imaging body 33, effecting yielding of the first and second rotating bars 432 and 433, during which the first rotating bar 432 rotates about the rotation axis relative to the first imaging module 31, e.g., imaging body 33, and the second rotating bar 433 rotates about the rotation axis relative to the second imaging module 32, e.g., imaging body 33. Finally, the first imaging module 31 and the second imaging module 32 are slid synchronously by the slide lever 431 to the state shown in fig. 6 at the time of pupil distance adjustment.

In some embodiments, the sliding rod 431 is limited by the aperture of the movable hole 1003, so that the sliding rod 431 cooperates with the first rotating rod 432 and the second rotating rod 433 to realize sliding. In some embodiments, the sliding direction of the sliding rod 431 may be perpendicular to the sliding direction of the first imaging module 31 relative to the mounting plate 20, may be perpendicular to the sliding direction of the second imaging module 32 relative to the mounting plate 20, and may not be perpendicular to the sliding direction of the first imaging module 31 relative to the mounting plate 20, or may not be perpendicular to the sliding direction of the second imaging module 32 relative to the mounting plate 20.

In some embodiments, the sliding rod 431 may also be slidably connected to the mounting plate 20 through a sliding rail, a sliding groove, a clamping connection, or the like. In some embodiments, the slide bar 431 may be located within the mounting space 1001 without protruding from the moveable aperture 1003 within the mounting space 1001.

In some scenarios, a user may touch the first distance adjusting member 41, such as the connecting rod 411, then toggle the first distance adjusting member 41, such as the connecting rod 411, and the first distance adjusting member 41, such as the connecting rod 411, may slide in the movable hole 1003, may slide to a side close to the second imaging module 32, such that the first distance adjusting member 41, such as the connecting rod 411, is driven to the first imaging module 31, such as the imaging module 33, to enable the first imaging module 31, such as the imaging module 33, to slide relative to the mounting plate 20, such that the first imaging module 31, such as the imaging module 33, may slide to a side close to the second imaging module 32, and simultaneously, with the cooperation of the first rotating rod 432, such that the sliding rod 431 slides, the second rotating rod 433 rotates about the rotation axis relative to the sliding rod 431, and under spatial interference, such that the sliding rod 431 moves to a side close to the first imaging module 31, such as the imaging module 33, to enable the second rotating rod 433 to be rotated about the rotation axis relative to the second imaging module 32, such as the rotation axis 433. The first imaging module 31 and the second imaging module 32 can slide synchronously in the pupil distance adjusting process.

The first imaging module 31 and the second imaging module 32 can slide synchronously in the pupil distance adjusting process.

In some scenarios, a user may touch the second distance adjusting member 42, such as the connecting rod 411, then toggle the second distance adjusting member 42, such as the connecting rod 411, where the second distance adjusting member 42, such as the connecting rod 411, may slide in the movable hole 1003, may slide to a side close to the first imaging module 31, such that the second distance adjusting member 42, such as the connecting rod 411, is driven to the second imaging module 32, such as the imaging body 33, to enable the second imaging module 32, such as the imaging body 33, to slide relative to the mounting plate 20, such that the second imaging module 32, such as the imaging body 33, may slide to a side close to the first imaging module 31, while under the cooperation of the second rotating rod 433, such that the sliding rod 431 slides, the first rotating rod 432 rotates relative to the sliding rod 431 about the rotation axis, and under spatial interference, the sliding of the sliding rod 431 moves the first imaging module 31, such as the imaging body 33, to a side close to the second imaging module 32, such as the imaging body 33, to enable the first rotating rod 432 to yield the first rotating rod 432 relative to the first imaging module 31, such as the imaging body 33, about the rotation axis. The first imaging module 31 and the second imaging module 32 can slide synchronously in the pupil distance adjusting process.

The first imaging module 31 and the second imaging module 32 can slide synchronously in the pupil distance adjusting process.

Referring to fig. 8 and 9, fig. 8 is a schematic diagram illustrating the configuration of the display assembly 30 and the adjustment assembly 40 shown in fig. 6 in accordance with other embodiments. Fig. 9 is a schematic view of the adjustment assembly 40 of fig. 8 mated in some embodiments. The first rotating rod 432 may not be rotatably connected to the first imaging module 31, for example, the imaging main body 33, but may be connected to the first distance adjusting member 41, for example, the connecting rod 411, through a universal transmission, a universal joint, a universal shaft, or the like, so that the first rotating rod 432 may also achieve transmission when an included angle is formed between the first rotating rod 432 and the first distance adjusting member 41, for example, the connecting rod 411.

The second rotating rod 433 may not be rotatably connected to the second imaging module 32, for example, the imaging main body 33, but may be connected to the second distance adjusting member 42, for example, the connecting rod 411, through a universal drive, a universal joint, a universal shaft, etc., so that the second rotating rod 433 may also realize a drive when an included angle is formed between the second rotating rod 433 and the second distance adjusting member 42, for example, the connecting rod 411.

The end of the slide rod 431 located in the installation space 1001 is rotatably connected to the adapter 4311. The adaptor 4311 is rotatably connected to a first adaptor shaft 4312 and a second adaptor shaft 4313. The first adapter shaft 4312 and the second adapter shaft 4313 can be directly or indirectly connected to the slide rod 431 in a driving manner. In some embodiments, the first adapter shaft 4312 and the second adapter shaft 4313 are disposed on opposite sides of the sliding rod 431, and of course, the positional relationship between the first adapter shaft 4312, the second adapter shaft 4313 and the sliding rod 431 can be adjusted according to the requirements of those skilled in the art.

Finally, the first imaging module 31 and the second imaging module 32 slide synchronously during pupil distance adjustment by the slide rod 431.

In some scenarios, a user may touch the slide rod 431 and then pull the slide rod 431, such that the slide rod 431 pulls the first and second rotating rods 432 and 433 with the cooperation of the adapter 4311, the first and second adapter 4312 and 4313, and the first and second rotating rods 432 and 433 are rotated about the rotation axis with respect to the slide rod 431, and the pulling of the slide rod 431 causes the first imaging module 31, e.g., the imaging main body 33, to move toward a side near the second imaging module 32, e.g., the imaging main body 33, under the action of the first distance adjusting member 41, and the second imaging module 32, e.g., the imaging main body 33, to move toward a side near the first imaging module 31, e.g., the imaging main body 33, under the action of the second distance adjusting member 42, such that the first and second rotating rods 432 and 433 are allowed to be in a space interference, during which the first and second rotating rods 432 and 433 are rotated about the rotation axis with respect to the second distance adjusting member 41. Finally, the first imaging module 31 and the second imaging module 32 slide synchronously during pupil distance adjustment by the slide rod 431.

In some embodiments, the connecting rod 411 may be omitted and the driving mechanism 413 may be directly connected and fixed to the gear 412. For example, gear 412 may be directly fixed to the output shaft of the electrode.

In some embodiments, the connecting rod 411 may not be connected to the gear 412, and the gear 412 may be drivingly connected to the driving mechanism 413, and the connecting rod 411 may be fixed to the imaging body 33 and protrude from the movable hole 1003 in the installation space 1001.

In some embodiments, the ratchet 3425 on the ratchet 342 may be changed in arrangement, for example, in the form of a gear of a worm gear, and thus the ratchet 342 may be also referred to as a "worm gear", and accordingly, the gear 412 on the first distance adjusting member 41 may be changed, for example, in the form of a helical tooth, to be driven by the helical tooth engaged with the gear of the worm gear, and thus the first distance adjusting member 412 may be also referred to as a "worm". The worm wheel and the worm are matched to form a staggered shaft gear pair, so that worm transmission is realized, the worm is used as a driving gear to perform speed reduction transmission, and the reverse stroke self-locking effect is realized. In some embodiments, the connecting rod 411 may not be part of a worm, and the connecting rod 411 may be fixed to the imaging body 33 and protrude from the movable hole 1003 in the installation space 1001.
