Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

The interpupillary distance is the distance between the pupils of both eyes. Generally, the eyes of a person watch the same object, the object is imaged at the retinas of the two eyes respectively and is overlapped at the visual center of the brain to form a complete single object with three-dimensional effect, and the function is called single vision of the two eyes. The interpupillary distance of an adult is typically between 55-70 mm.

With the technological progress, users using virtual reality equipment gradually increase, and due to the fact that the interpupillary distance of each user is different, if the distance between the centers of the two lens barrel assemblies of the virtual reality equipment is different from the interpupillary distance of each user, a human body can generate a prism effect. The prism effect is that the optical center of the lens barrel assembly is inconsistent with the pupil center of human eyes to form a prism, so that the human eyes receive multiple beams of light to cause visual injury, and the phenomenon that the visual injury of the human eyes is caused due to the pupil distance deviation can be understood. At this moment, the comfort level that the user wore virtual reality equipment can obviously descend, if the prism effect is great, when interpupillary distance deviation is great promptly, the user can demonstrate symptoms such as dizziness, nausea even, consequently need add interpupillary distance adjustment structure in virtual reality equipment, through the interval at two lens cone subassembly centers in adjusting virtual reality equipment, makes virtual reality equipment and every user's interpupillary distance match. However, the current adjusting structure has a plurality of problems, for example, an extra component for switching the transmission direction is needed between the motor and the transmission piece, so that the transmission chain is too long; the structure is more complex; the position of motor placement is unreasonable, the thickness of virtual reality equipment is increased, and the like.

In view of the above, in order to solve the above problems, the present application provides an adjusting structure, please refer to fig. 1-4 together, and fig. 1 is a perspective view of an adjusting structure according to an embodiment of the present application. Fig. 2 is an exploded view of fig. 1 in an embodiment of the present application. Fig. 3 is a top view of the adjustment structure of fig. 1 when the adjustment structure reaches a minimum adjustment range value in an embodiment of the present application. FIG. 4 is a top view of the tuning structure of FIG. 1 as it reaches a tuning range maximum in one embodiment of the present application.

The embodiment provides an adjusting structure 1, which comprises two display modules 10, two lens cone assemblies 20, a first motor 30 and a transmission part 40, wherein each of the two display modules 10 is provided with a display surface 11; one lens cone assembly 20 is mounted on one display module 10, and the other lens cone assembly 20 is mounted on the other display module 10; at least part of the first motor 30 is arranged between the two display modules 10, and the extending direction of the first motor 30 is parallel to the display surface 11; the transmission member 40 is rotatably connected to the first motor 30, at least a portion of the two display modules 10 is rotatably connected to two opposite sides of the transmission member 40, and the rotation direction of the transmission member 40 is perpendicular to the display surface 11;

when the first motor 30 rotates, the transmission member 40 is driven to rotate, so as to drive the two display modules 10 and the two lens cone assemblies 20 to move in a direction away from the transmission member 40 or close to the transmission member 40, and the moving directions of the two display modules 10 are parallel to the display surface 11.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. The terms "first," "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order.

The adjusting structure 1 provided in this embodiment is a structure that controls the transmission member 40 through the first motor 30, so as to adjust the distance between the centers of the display module 10 and the lens barrel assembly 20. The adjustment structure 1 provided in the present embodiment may include various components, and the present embodiment is schematically described only by applying the adjustment structure 1 to a virtual reality device. This does not mean that the adjustment structure 1 of the present embodiment is necessarily applied to a virtual reality apparatus. In other embodiments, the adjustment structure 1 can also be applied in other fields, such as the display field, the measurement field, etc.

The adjusting structure 1 provided by the present embodiment includes a display module 10, and the display module 10 includes a display surface 11 and a comprehensive module having other functions such as displaying a picture and prompting information, which is formed by other various structural members. The display surface 11 is generally used for displaying a screen, characters, and the like for a user to receive information. The display surface 11 provided in the present application may be a member having any shape, and the present application does not limit this. Further optionally, in this embodiment, the display surface 11 is square. The present application will be described in detail below with respect to a specific structure of the display module 10.

The adjusting structure 1 provided by the present embodiment further includes a lens barrel assembly 20, where the lens barrel assembly 20 is a comprehensive assembly composed of a lens barrel and various lenses, and the light transmitted by the display module 10 is finally transmitted to the eyes of the user through the lenses, and the user presents a complete and clear image in the eyes. One lens barrel assembly 20 is mounted on one display surface 11, and the other lens barrel assembly 20 is mounted on the other display surface 11. Because the user observes the image of display surface 11 in virtual reality equipment, different with the angle, distance, light etc. condition that the user directly observed the image, for make the user obtain real experience through virtual reality equipment, reach the effect that the user directly observed the image, consequently set up lens cone subassembly 20 in virtual reality equipment usually, make the picture or the information in the display surface 11 of display module assembly 10 pass through lens cone subassembly 20 earlier, in the eyes of user again, so that the imaging effect of display module assembly 10 produces experience and the third dimension that is close with reality in the user's mind. It should be noted that when the adjusting structure 1 works to adjust the pupil distance matching with the user, the adjusting effect can be achieved by adjusting the display module 10 and the lens barrel assembly 20 simultaneously. As to the specific structure of the lens barrel assembly 20, the present application will be described in detail below.

The adjusting structure 1 provided by the present embodiment further includes a first motor 30, and the first motor 30 is generally connected to other components to drive the other components to move. The first motor 30 provided in the present application may be a component having any shape, and the present application is not limited thereto, and the first motor 30 may drive other components to move. Optionally, the first motor 30 in this embodiment has a power-off self-locking function. The power-off self-locking function is understood to be that the driving member 40 is driven by a motor to drive the display module 10 and the lens barrel assembly 20 to move to adjust the interpupillary distance, and when the first motor 30 is powered off and self-locked, the first motor 30 stops rotating, so that the driving member 40 is locked, and the display module 10 and the lens barrel assembly 20 are also locked. In addition, even if the virtual reality device is powered off, because the first motor 30 has a power-off self-locking function, the display module 10 and the lens cone assembly 20 of the adjusting structure 1 are locked, the adjusting structure 1 can still keep the interpupillary distance matched with the user, and the convenience for the user to use is improved. Therefore, the self-locking function of the first motor 30 in this embodiment avoids an additional locking structure in the related art, wherein the locking structure can also be understood as a limiting structure for fixing the display module 10 and the lens assembly, so that by using the first motor 30 with the power-off self-locking function, the structure can be further simplified, the internal space occupied by the adjusting structure 1 can be reduced, and the manufacturing cost can be reduced.

In the field of virtual reality technology, a part of the adjusting structure 1 needs to be manually adjusted, and there are often many problems, such as low precision of adjusting the interpupillary distance; the adjusted gears are fewer, so that the pupil distance of the virtual reality equipment and the pupil distance of a part of users cannot be matched; the effect of the limiting structure for fixing the display module 10 and the lens barrel assembly 20 is poor.

However, in the present embodiment, by additionally providing the first motor 30, the driving member 40 can be driven by the first motor 30, so that the driving member 40 controls the display module 10 and the lens barrel assembly 20 to move in a direction away from the driving member 40 or close to the driving member 40, thereby improving the precision of adjusting the interpupillary distance. Further optionally, the first motor 30 has a self-locking function. The self-locking function of the first motor 30 is described above in detail and will not be described herein. The self-locking function of the first motor 30 can also be understood as an additional limit structure in the related art. In this embodiment, the first motor 30 having a self-locking function is additionally provided, so that the reliability of fixing the display module 10 and the lens barrel assembly 20 can be improved, and the structure of the virtual reality device can be further simplified.

The adjustment structure 1 provided in this embodiment further includes a transmission member 40, and the transmission member 40 is generally connected to other structural components for transmitting power to the connected components. The material of the transmission member 40 includes, but is not limited to, plastic, metal, etc., and the transmission member 40 provided in this application is not limited to be provided and may be a member with any shape, and it is sufficient that the transmission member 40 connects the first motor 30 and the two display modules 10. Optionally, in the present embodiment, the first motor 30 and the transmission member 40 are disposed on one side of the two display surfaces 11 close to the lens barrel assemblies 20, and at least a portion of the first motor 30 and at least a portion of the transmission member 40 are disposed between the two lens barrel assemblies 20.

Moreover, since at least a portion of the two display modules 10 are rotatably connected to two opposite sides of the transmission member 40, when the transmission member 40 rotates, the two display modules 10 and the two lens barrel assemblies 20 can move toward a direction close to each other and a direction away from each other, so as to change the distance between the centers of the two display modules 10 and the two lens barrel assemblies 20 to match the interpupillary distance of the user. The center of the lens barrel assembly 20 is the center of the lens in the lens barrel assembly 20, i.e. the intersection point of the optical axis and the lens.

Alternatively, the structure of the transmission member 40 may be, but is not limited to, a gear assembly, a belt, and the like. Further alternatively, in the present embodiment, the transmission member 40 is a ring gear having a circle of external teeth, and the external teeth of the transmission member 40 are rotatably connected to the two display modules 10.

Further optionally, the transmission member 40 of the present embodiment is a ring gear with a circle of external teeth, and the number of teeth of the transmission member 40 is equal to the preset number of teeth, so that the adjusting structure 1 can be adjusted at will within the preset interpupillary distance range. Through design driving medium 40, make first motor 30 and driving medium 40 cooperate to can make and adjust structure 1 and can adjust wantonly in the range of predetermineeing the interpupillary distance, realize adjusting the electrodeless regulation of structure 1 promptly, in order to avoid adjusting the too few problem of gear among the correlation technique. The stepless adjustment means that the adjustment mode is not a jump type, but is relatively smooth adjustment in a range.

As shown in fig. 1, in the adjusting structure 1 of the present embodiment, the first motor 30 and the transmission member 40 are disposed between the two display modules 10, which can also be understood as that the first motor 30 and the transmission member 40 occupy the space between the two display modules 10, so as to reduce the occupied internal space of the virtual reality device, thereby reducing the thickness of the virtual reality device, and the extending direction of the first motor 30 (as shown in the direction D1 in fig. 1) is parallel to the display surface 11, that is, the extending direction in which the first motor 30 is disposed is prevented from being perpendicular to the display surface 11, and further, the thickness of the virtual reality device is prevented from being larger due to the disposition of the first motor 30.

Secondly, in the present embodiment, the extending direction of the first motor 30 is parallel to the display surface 11, that is, the rotating direction (as shown in the direction D2 in fig. 1) of the first motor 30 is perpendicular to the display surface 11, and the rotating member 60 is rotatably connected to the first motor 30, and the rotating direction (as shown in the direction D2 in fig. 1) of the rotating member 60 is also perpendicular to the display surface 11, so that the transmission direction of the first motor 30 is the same as the rotating direction of the transmission member 40, and the first motor 30 can directly drive the transmission member 40 to rotate without adding an additional component for converting the transmission direction in the related art, that is, the first motor 30 can directly drive the display module 10 and the lens barrel assembly 20 to simultaneously move in the direction (as shown in the direction D3 in fig. 1) away from or close to the transmission member 40 through the transmission member 40, and adjust the distance between the centers of the lens barrel assemblies 20 to match the interpupillary distance of the user, thereby simplifying the structure, the problems of overlong transmission chain and complex structure are avoided.

In summary, in the embodiment, the first motor 30 and the transmission member 40 are disposed between the display modules 10, and the extending direction (as shown in the direction D1 in fig. 1) of the first motor 30 is parallel to the display surface 11, and the rotating direction (as shown in the direction D2 in fig. 1) of the transmission member 40 is perpendicular to the display surface 11, so as to limit the placement of the first motor 30 and the transmission chain between the first motor 30 and the transmission member 40, and further improve the adjustment structure 1, which not only improves the compactness of the adjustment structure 1, but also avoids the thickness of the virtual reality device being larger, and simplifies the structure, and avoids the problems of overlong transmission chain and complex structure.

The speed reduction unit 41 of the present embodiment changes only the rotational speed without changing the transmission direction, thereby changing the torque. The present application will be described in detail below with respect to the specific structure of the speed reduction assembly 41. The speed reducing component 41 is rotatably connected between the first motor 30 and the transmission member 40, and it can also be understood that the first motor 30 indirectly rotatably connects the transmission member 40 through the speed reducing component 41; and the rotation direction of the speed reducing assembly 41 is perpendicular to the display surface 11, i.e. the rotation direction of the speed reducing assembly 41 (as shown in the direction D2 in fig. 5), the rotation direction of the first motor 30 (as shown in the direction D2 in fig. 5), and the rotation direction of the transmission member 40 (as shown in the direction D2 in fig. 5) are the same, so that it is not necessary to add an additional component for converting the transmission direction in the related art. Therefore, by additionally arranging the speed reducing component 41 and limiting the arrangement position and the rotation direction of the speed reducing component 41, the compactness of the adjusting structure 1 can be ensured to be improved, the thickness of the virtual reality device is prevented from being larger, the structure is simplified, the overlong transmission chain and the complex structure are avoided, and meanwhile, the gear rotating speed and the torque can be further reduced and increased through the speed reducing component 41, so that the reliability of the first motor 30 for controlling the transmission part 40 is further improved.

Further alternatively, please refer to fig. 6, in which fig. 6 is a schematic cross-sectional view of the deceleration assembly along a direction a-a in fig. 5 according to another embodiment of the present disclosure. As shown in fig. 6, the speed reducing assembly 41 further includes a first sub gear 411, a second sub gear 412, a third sub gear 413, a fourth sub gear 414, a first rotating shaft 415, and a second rotating shaft 416, the first sub gear 411 is rotatably connected to the first motor 30 and the second sub gear 412, the second sub gear 412 and the third sub gear 413 are coaxially coupled and rotated by the first rotating shaft 415, the third sub gear 413 is rotatably connected to the fourth sub gear 414, and the fourth sub gear 414 is coaxially coupled and rotated with the transmission member 40 by the second rotating shaft 416.

In the first movement state, when the first motor 30 drives the transmission member 40 to rotate in a first predetermined direction (as shown in a direction D4 in fig. 8), the two display modules 10 and the two lens barrel assemblies 20 move simultaneously in a direction approaching the transmission member 40 (as shown in a direction D5 in fig. 8), and the movement directions of the two display modules 10 are parallel to the display surface 11. In the second movement state, when the first motor 30 drives the transmission member 40 to rotate in the second predetermined direction (as shown in the direction D6 in fig. 9), the two display modules 10 and the two lens barrel assemblies 20 move simultaneously in the direction away from the transmission member 40 (as shown in the direction D7 in fig. 9), and the movement direction of the two display modules 10 is parallel to the display surface 11. Therefore, by arranging the brackets and limiting the placement of the brackets, the transmission chains from the first motor 30 to the transmission member 40, the transmission member 40 to the first bracket 12a and the second bracket 12b can be obtained, and then the adjusting structure 1 can control the two motion states by the motors by utilizing the transmission chains so as to match the interpupillary distance of each user, thereby simplifying the adjusting structure 1 and improving the compactness of the adjusting structure 1. In addition, at least a part of the second support 12b is disposed opposite to the first support 12a, that is, the two display surfaces 11 connected to the first support 12a and the second support 12b may be disposed in parallel or may be disposed in a staggered manner. The staggered arrangement means that a gap is formed between the two display surfaces 11.

Next, a detailed structure of the second bracket 12b will be described, please refer to fig. 10 and 11 together, and fig. 10 is a perspective view of an adjustment structure according to another embodiment of the present application. FIG. 11 is a top view of the adjustment mechanism of FIG. 10 in accordance with yet another embodiment of the present application. In this embodiment, the second frame 12b includes a first portion 121 and a second portion 122, the first portion 121 is connected to the periphery of the second display element 10b, the second portion 122 is connected to the first portion 121 in a bent manner, and the second portion 122 is farther from the first display element 10a than the second display element 10 b; the second portion 122 is rotatably connected to the first frame 12a at two opposite sides of the transmission member 40.

The second bracket 12b provided in this embodiment further includes a first portion 121 and a second portion 122, and the first portion 121 and the second portion 122 may be members with any shapes, which is not limited in this application, and only the first portion 121 is connected to the second display module 10b, and the second portion 122 is connected to the first portion 121 in a bending manner. Alternatively, the first portion 121 may be connected to both the second stand 12b and the display stand 11 a; the first portion 121 and the second portion 122 may be integrally formed structural members, or may be separately formed and assembled structural members.

As shown in fig. 10, the second portion 122 is far away from the first display assembly 10a than the second display assembly 10b, and the second portion 122 and the first bracket 12a are rotatably connected to opposite sides of the transmission member 40, it can also be understood that the second display assembly 10b and the first display assembly 10a are disposed on the same side of the transmission member 40, and it should be noted that, in this case, the two display surfaces 11 may be disposed in parallel or alternatively. The staggered arrangement means that a gap is formed between the two display surfaces 11. Therefore, in the present embodiment, the first portion 121 and the second portion 122 are connected in a bending manner, and the position of the second portion 122 is limited, so that the compactness of the adjustment structure 1 can be ensured to be improved, the thickness of the virtual reality device is prevented from being large, the structure is simplified, the second display assembly 10b and the first display assembly 10a are arranged on the same side while the transmission chain is prevented from being too long and the structure is prevented from being complex, the adjustment structure 1 is more suitable for the observation habit of the human body, and excessive adjustment of other components for the purpose of making the image of the display module 10 reach the eyes of the user at the same time is prevented.

As shown in fig. 12, when the two display modules 10 and the two lens barrel assemblies 20 move towards the direction of approaching the transmission member 40 simultaneously, the first frame 12a approaches the second frame 12b gradually, and since the first portion 121 has the first receiving groove 121a capable of receiving at least a part of the first frame 12a, the first frame 12a can continue to move towards the first portion 121 (as shown in the direction of D8 in fig. 12) until the first frame 12a abuts against the bottom wall of the first receiving groove 121 a. However, if the first portion 121 does not have the first receiving groove 121a, the first holder 12a cannot move further if the first holder 12a abuts against the first portion 121. Therefore, in the present embodiment, the compactness of the adjustment structure 1 is ensured to be improved, the thickness of the virtual reality device is prevented from being large, the structure is simplified, the overlong transmission chain and the complex structure are avoided, and meanwhile, the adjustment range of the adjustment structure 1 is expanded by arranging the first accommodating groove 121 a.

The extending direction of the first housing 50 (as shown by the direction D3 in fig. 14) is parallel to the rotating direction of the transmission member 40 (as shown by the direction D2 in fig. 14) and perpendicular to the extending direction of the first motor 30 (as shown by the direction D1 in fig. 14). Alternatively, as shown in fig. 14, at least a portion of the display stand 11a abuts the body 501. The material of the first housing 50 includes, but is not limited to, plastic, metal, and the like.

The shape of the second receiving groove 502a is not limited in the present application, as long as the second receiving groove 502a can receive at least a portion of the first display element 10a and at least a portion of the second display element 10 b. In actual production, the body 501, the first extension 502 and the second extension 503 may be integrally formed structural members, but for convenience of understanding, the body 501, the first extension 502 and the second extension 503 are artificially named differently.

As shown in fig. 14, when the two display modules 10 move away from the transmission member 40 or approach the transmission member 40 or stop moving, at least a portion of the first display module 10a and at least a portion of the second display module 10b are always disposed in the second receiving groove 502a, i.e., the first extending portion 502 is always abutted to at least a portion of the first display module 10a and at least a portion of the second display module 10 b. Therefore, by additionally providing the first housing 50 and enabling the first extending portion 502 to always abut against at least a part of the first display assembly 10a and at least a part of the second display assembly 10b, the first housing 50 provides at least a part of the display module 10 with abutting force (as shown by F1 in fig. 14) to support the display module 10, so that the distance between the centers of the lens barrel assemblies 20 matches with the pupil distance of the user, the reliability of the adjusting structure 1 is improved, and the accuracy of adjusting the pupil distance is improved.

Fig. 18 is a schematic view of another embodiment of the first mating portion and the second mating portion of fig. 16 according to the present application.

In this embodiment, a first engaging portion 504 is disposed on a side of the second extending portion 503 close to the first bracket 12a and the second bracket 12b, a second engaging portion 123 is disposed on a side of the first bracket 12a and the second bracket 12b close to the first housing 50, and the first engaging portion 504 and the second engaging portion 123 are capable of engaging with each other, so that the first bracket 12a and the second bracket 12b slide relative to the second extending portion 503.

The second extension 503 of the present embodiment further has a first engaging portion 504, and the first bracket 12a and the second bracket 12b further have a second engaging portion 123. In practical production, the second extending portion 503 and the first matching portion 504 may be integrally formed structural members, and the second matching portion 123 and the first bracket 12a, and the second bracket 12b may also be integrally formed structural members; however, the second extension 503, the first fitting portion 504, the second fitting portion 123, the first bracket 12a, and the second bracket 12b are named differently for the sake of understanding below. In addition, the shape of the first mating portion 504 and the second mating portion 123 is not limited in the present application, as long as the first mating portion 504 and the second mating portion 123 can be mated with each other. The present application will be described in detail below with respect to the detailed structure of the first and second mating portions 504 and 123.

As shown in fig. 16, when the first engaging portion 504 and the second engaging portion 123 are engaged, the second extending portion 503 is connected to at least a portion of the first bracket 12a and at least a portion of the second bracket 12b, and when the two display modules 10 are simultaneously moved in a direction away from the driving member 40 or close to the driving member 40 (as shown in a direction D3 in fig. 16), the first bracket 12a and the second bracket 12b can also slide relative to the second extending portion 503. In addition, when the two display modules 10 stop moving, the first engaging portion 504 and the second engaging portion 123 are engaged with each other all the time to further support and fix the display modules 10. Therefore, by providing the first engaging portion 504 and the second engaging portion 123, the first housing 50 can be connected to the display module 10 to further fix and limit the movement of the display module 10, thereby improving the reliability of the adjusting structure 1 and improving the accuracy of adjusting the interpupillary distance.

Next, the detailed structure of the first fitting portion 504 and the second fitting portion 123 will be described. Alternatively, the first mating portion 504 includes a latching groove 504a or a latching block 504b, as shown in fig. 17, when the first mating portion 504 is the latching groove 504a, the second mating portion 123 is the latching block 504 b; alternatively, as shown in fig. 18, when the first mating portion 504 is the latch 504b, the second mating portion 123 is the latch slot 504 a. When the first engaging portion 504 engages with the second engaging portion 123, at least a portion of the latch 504b is disposed in the latch groove 504a, so that the first bracket 12a and the second bracket 12b slide relative to the second extending portion 503. In addition, although fig. 17 and 18 schematically illustrate the second engagement portion 123 and the first engagement portion 504 of the first bracket 12a, the second engagement portion 123 and the first engagement portion 504 of the second bracket 12b may be engaged with each other in another embodiment.

Optionally, please refer to fig. 19 and 20 together, and fig. 19 is a perspective view of an adjusting structure according to another embodiment of the present application. Fig. 20 is a partially enlarged view of fig. 19. In this embodiment, the first housing 50 further includes a third extending portion 505 and a fourth extending portion 506, the third extending portion 505 is connected to the first extending portion 502 in a bending manner, the fourth extending portion 506 is connected to the second extending portion 503 in a bending manner, the third extending portion 505 and the fourth extending portion 506 are both disposed on one side of the first housing 50 close to the display module 10, the body 501, the first extending portion 502 and the third extending portion 505 are enclosed to form a first fitting space 505a, and at least a portion of the first display assembly 10a and at least a portion of the second display assembly 10b are disposed in the first fitting space 505 a; the body 501, the second extending portion 503 and the fourth extending portion 506 enclose a second fitting space 506a, and at least a portion of the first bracket 12a and at least a portion of the second bracket 12b are disposed in the second fitting space 506 a. The extending directions of the third extending portion 505 and the fourth extending portion 506 are perpendicular to the extending direction of the first motor 30.

As shown in fig. 19, when the two display modules 10 move away from the transmission member 40 or approach the transmission member 40 or stop moving at the same time, at least a portion of the first display module 10a and at least a portion of the second display module 10b are disposed in the first fitting space 505a, and at least a portion of the first bracket 12a and at least a portion of the second bracket 12b are disposed in the second fitting space 506 a. It can also be understood that the first housing 50 is always abutted against at least a portion of the display module 10, i.e. the first housing 50 always provides an abutting force to the display module 10 to support and fix the display module 10. Therefore, by adding the third extension part 505 and the fourth extension part 506 to the first housing 50, the display module 10 can slide along the extension direction of the first housing 50 (as shown in the direction D3 in fig. 19) to further limit the movement of the display module 10, and the first housing 50 can provide a contact force to the display module 10 to perform the fixing and supporting functions, thereby further improving the reliability of the adjustment structure 1 and improving the accuracy of adjusting the interpupillary distance.

Please refer to fig. 21 and 22 together, fig. 21 is a perspective view of an adjustment structure according to another embodiment of the present application. FIG. 22 is a top view of the adjustment structure of FIG. 21 with the first housing removed in yet another embodiment of the present application.

In the present embodiment, a gap is provided between a surface of the first holder 12a on the side closer to the lens barrel assembly 20 and a surface of the second holder 12b on the side closer to the first housing 50.

A gap is formed between the surface of the first holder 12a on the side close to the lens barrel assembly 20 and the surface of the second holder 12b on the side close to the first housing 50, and it can also be understood that the perpendicular distance (as shown in H1 in fig. 22) from the surface of the first holder 12a on the side close to the lens barrel assembly 20 to the surface of the second holder 12b on the side close to the first housing 50 is not zero. It should be noted that the two display surfaces 11 may be arranged in parallel or may be arranged in a staggered manner. The staggered arrangement means that a gap is formed between the two display surfaces 11.

As shown in fig. 22, when the two display modules 10 and the two lens barrel assemblies 20 move towards the direction approaching the transmission member 40 at the same time, the first frame 12a gradually approaches the second frame 12b, and because there is a gap between the surface of the first frame 12a on the side approaching the lens barrel assemblies 20 and the surface of the second frame 12b on the side approaching the first housing 50, the first frame 12a can continue to move towards the direction approaching the second frame 12b without touching the second frame 12 b. Therefore, when there is a gap between the surface of the first holder 12a on the side close to the lens barrel assembly 20 and the surface of the second holder 12b on the side close to the first housing 50, that is, the vertical distance (as shown by H1 in fig. 22) from the surface of the first holder 12a on the side close to the lens barrel assembly 20 to the surface of the second holder 12b on the side close to the first housing 50 is not zero, the first holder 12a does not abut against the second holder 12b, so that the first holder 12a cannot move any further. Therefore, in the present embodiment, by adjusting the relative positions of the first support 12a and the second support 12b, the compactness of the adjustment structure 1 is ensured to be improved, the thickness of the virtual reality device is prevented from being large, the structure is simplified, the overlong transmission chain and the complex structure are avoided, and the adjustment range of the adjustment structure 1 is further expanded.

In the process of using the virtual reality device by the user, since the near-sighted population is large at present, especially in the young people, and the degree of myopia or hyperopia of each user is different, the virtual reality device also needs to be matched with each user to perform diopter adjustment. The dioptric phenomenon is a phenomenon in which when light is incident from an object to another substance having a different optical density, the direction of propagation of the light is deflected, and the unit representing the magnitude (refractive power) of the dioptric phenomenon is diopter (abbreviated as "D"). The 1D power is equivalent to focusing parallel rays at a focal length of 1 meter, and the stronger the power, the shorter the focal length. Typically, the diopter of a myopic population is expressed by negative values, and typically, the diopter of a hyperopic population is expressed by positive values. The greater the difference between diopters and zero, the more severe the user's near or far vision. If the diopter of the virtual reality equipment is not matched with the user, the definition of the image and the information obtained by the user is easily reduced. However, there are many problems in the current structure for adjusting diopter, such as low universality of the way of customizing each user-specific lens, inaccurate manual adjustment, complicated structure and more space occupation.

Therefore, the present embodiment improves the clarity of images and information obtained by the user by adjusting the lens barrel assembly 20 to match the diopter of the virtual reality device with the user. Next, the present application will describe the detailed structure of the barrel assembly 20.

Please refer to fig. 23 and 24 together, fig. 23 is a perspective view of an adjustment structure according to another embodiment of the present application. Fig. 24 is an exploded view of fig. 23 in yet another embodiment of the present application. In this embodiment, the lens barrel assembly 20 includes a lens barrel 21 and at least one lens 22, the lens barrel 21 has a first accommodating space 21a, the at least one lens 22 is disposed in the first accommodating space 21a, and the lens barrel 21 is connected to the display surface 11;

the adjusting structure 1 further comprises a rotating part 60 and a second motor 70, the lens barrel 21 is sleeved with the rotating part 60 and the second motor 70, the rotating part 60 is rotatably connected with the second motor 70, and the rotating part 60 is connected with the lens barrel 21; when the second motor 70 rotates, the rotating member 60 is driven to rotate, and then the lens barrel 21 is driven to rotate, so that at least one of the lenses 22 moves in a direction perpendicular to the display surface 11.

The lens barrel assembly 20 provided in the present embodiment further includes a lens barrel 21, and the lens barrel 21 is used to connect, support, or fit other components. At least part of the first motor 30 and at least part of the transmission member are provided between the two lens barrels 21. The shape of the lens barrel 21 is not limited in the present application, and only the lens barrel 21 has the first accommodation space 21a therein, and the at least one lens 22 is provided in the first accommodation space 21 a. It should be noted that the lens barrel 21 and the display module 10 can move simultaneously in a direction away from or close to the transmission member 40, but the lens barrel 21 cannot move relative to the display module 10. The lens barrel assembly 20 provided by the present embodiment further includes at least one lens 22, the lens 22 provided by the present application can be, but is not limited to, a convex lens, a concave lens, a plano lens, etc., and only the at least one lens 22 can be matched with the lens barrel 21 to adjust diopter. In the present embodiment, the diopter is adjusted by adjusting the distance that the lens 22 is perpendicular to the display module 10, so that the image of the display module 10 passes through the lens 22 in the lens barrel 21, and then is displayed in front of the eyeball of the user with reasonable size, angle, focal plane, low distortion and other visual effects.

The adjusting structure 1 provided in this embodiment further includes a rotating member 60, and the rotating member 60 is connected to other structural components and can rotate the other components. The rotating member 60 provided in the present application is not limited, and may be a member having any shape, and the rotating member 60 may rotate the lens barrel 21. Optionally, the rotation element 60 may be fixedly connected, cooperatively connected, and the like with the lens barrel assembly 20, and the connection manner between the rotation element 60 and the lens barrel assembly 20 is not limited in this application, and only the rotation element 60 may drive at least one lens 22 in the lens barrel assembly 20 to move perpendicular to the display module 10. Furthermore, the adjusting structure 1 provided in this embodiment further includes a second motor 70, and the second motor 70 is generally connected to other components to drive the other components to move. The second motor 70 provided in the present application may be any shape of component, and the present application is not limited thereto, and the second motor 70 may drive the rotation member 60 to move. The specific structure of the lens barrel 21 and the lens 22 will be described in detail below.

Alternatively, the second electric machine 70 may employ an ultrasonic motor. By adopting the ultrasonic motor to control the rotating member 60, since the ultrasonic motor has the characteristics of low rotating speed and high torque, it can be ensured that the second motor 70 has higher control performance on the rotating member 60, and an additional speed reduction structure in the related art is not required to be added, so that the compactness of the adjusting structure 1 is improved, and the adjusting structure 1 is simplified.

As shown in fig. 23, the rotating element 60 and the second motor 70 are sleeved on the lens barrel 21, and it can also be understood that the rotating element 60 and the second motor 70 are both annular structural elements, so the lens barrel 21 in the present embodiment can penetrate through the rotating element 60 and the second motor 70, and the occupied internal space of the adjusting structure 1 is reduced, thereby reducing the thickness of the virtual reality device. In addition, in the present embodiment, the second motor 70 drives the rotating member 60, and the rotating member 60 drives the lens barrel 21, so that the lens barrel 21 rotates relative to the display surface 11, and thus the at least one lens 22 moves in a direction perpendicular to the display surface 11 (as shown in a direction D9 in fig. 23) to adjust the diopter, which is matched with each user. Therefore, in the present embodiment, the second motor 70 and the rotating member 60 are used to control the diopter of the adjusting structure 1, and the setting positions of the second motor 70 and the rotating member 60 are limited, so that not only the adjusting structure 1 can be simplified and the occupation of too much internal space can be avoided, but also the diopter adjusting precision can be improved compared with the manual adjustment in the related art.

Next, a detailed description is given of a specific structure of the lens barrel 21 and the lens 22, please refer to fig. 23 and 25 together, and fig. 25 is a schematic structural diagram of the lens barrel and the lens according to an embodiment of the present application. In this embodiment, the inner peripheral sidewall of the lens barrel 21 is provided with a first thread 21b, the outer peripheral sidewall of at least one of the lenses 22 is provided with a second thread 22a, and the first thread 21b and the second thread 22a are mutually matched to enable at least one of the lenses 22 to rotate relative to the lens barrel 21 and move in a direction perpendicular to the display surface 11. In addition, the shape of the first thread 21b and the second thread 22a is not limited in the present application as long as the first thread 21b and the second thread 22a can be engaged with each other.

As shown in fig. 23 and fig. 25, when the lens barrel 21 rotates relative to the display surface 11, due to the first thread 21b and the second thread 22a being engaged with each other, the lens barrel 21 drives the at least one lens 22 to rotate, and at this time, the at least one lens 22 rotates relative to the lens barrel 21 along the threads, so that the at least one lens 22 moves in a direction perpendicular to the display surface 11 (as shown in a direction D9 in fig. 23), which can also be understood as that the distance between the lenses 22 changes, so that the diopter of the adjusting structure 1 matches with the user, and thus, after the image of the display module 10 passes through the lenses 22 in the lens barrel 21, the image is presented in front of the eyeball of the user with visual effects of reasonable size, angle, focal plane, low distortion, and the like.

Optionally, please refer to fig. 26, fig. 26 is a perspective view of an adjusting structure according to another embodiment of the present application. The adjusting device in this embodiment further includes a second housing 80, the second housing 80 is disposed on a side of the lens barrel assembly 20 away from the display module 10, and has two first through holes 81 corresponding to the two lens barrel assemblies 20, and at least a part of the lens barrel assembly 20 penetrates through the first through holes 81. Further optionally, the second casing 80 further has a second receiving space, and the adjusting structure 1 is disposed in the second receiving space.

As shown in fig. 26, by additionally providing the second housing 80 and providing the second housing 80 with the first through hole 81, at least a portion of the lens barrel assembly 20 penetrates through the first through hole 81, so that the images and information of the two display modules 10 can be presented in front of the eyeball of the user through the two lens barrel assemblies 20. When ensuring that the second casing 80 does not influence the user to obtain images and information, the second casing 80 protects the adjusting structure 1, so that the service life of the adjusting structure 1 is prolonged, and even the appearance of the second casing 80 can be designed to improve the aesthetic property of the virtual reality device.

Fig. 28 is a perspective view of an adjustment structure of fig. 27 with a second housing 80 removed, according to yet another embodiment of the present application. Fig. 29 is an exploded view of fig. 27 in yet another embodiment of the present application. FIG. 30 is a top view of the adjustment mechanism of FIG. 27 in yet another embodiment of the present application.
