[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but cannot be understood as limiting the present application.

[0039] The embodiments of the present application can be applied to various application scenarios such as extended reality (eXtended ed Reality, XR), virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, AR), and mixed reality (Mixed Reality, MR).

[0040] Among them, Extended Reality (XR) is a concept that includes Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). It refers to the technology that creates an environment in which the virtual world is connected to the real world, and users can interact with the environment in real time.

[0041] Devices used to achieve extended reality are usually called extended reality devices, among which the more common ones are virtual reality devices, which are also called VR devices. VR devices are terminals for achieving virtual reality effects, and can usually be provided in the form of head-mounted devices, contact lenses, etc., to achieve visual perception and other forms of perception. Of course, the form of virtual reality devices is not limited to this, and can be further miniaturized or enlarged as needed. VR devices may also include a handle controller. As a peripheral device of the head-mounted device, the handle controller is used for users to operate and control the characters, environment, etc. of the virtual environment presented by the head-mounted device.

[0042] In the related art, in order to enable users to experience clear image images, head-mounted devices are usually used to adjust the distance between the lens barrels to adapt to the pupil distance of different users. Specifically, the adjustment device has a drive motor and a transmission mechanism, the transmission mechanism is connected between the drive motor and the lens barrel, and the drive motor is used to drive the lens barrel to move through the transmission mechanism to adjust the distance between the two relative lens barrels to adapt the user's pupil distance. Among them, the transmission mechanism usually includes a gear arranged on the output shaft of the drive motor, and a rack meshing with the gear, and the rack is fixedly connected to the lens barrel. However, in the above-mentioned adjustment device, the cost of the drive motor is relatively high, and the control panel of the head-mounted device also needs to be equipped with a function of controlling the drive motor, and the space occupied by the drive motor and the transmission mechanism is relatively large.

[0043] In order to overcome the above problems, the present embodiment provides a lens barrel adjustment device and a head-mounted device, wherein a threaded rod and an elastic stopper are provided, the threaded rod is connected to the lens barrels arranged oppositely, and the threaded rod can drive the lens barrels arranged oppositely to move in directions facing or away from each other under the action of an external force, so as to adjust the spacing of the lens barrels arranged oppositely, and after the adjustment is in place, the lens barrels and the base can be fixed by the elastic stopper cooperating with at least one of the plurality of slots, so that the lens barrels arranged oppositely are kept at the spacing. Compared with the fixed motor and the gear rack transmission mechanism in the related art, the lens barrel adjustment device in the present embodiment occupies a relatively small space, which is conducive to miniaturization, and there is no need to provide a drive motor, nor is there a need to add a control function for the drive motor to the control panel of the head-mounted device, which is conducive to reducing costs.

[0044] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 1 The figure is a three-dimensional schematic diagram of a lens barrel adjustment device provided in an embodiment. Figure 2FIG. 1 is a schematic diagram of the exploded structure of a lens barrel adjustment device provided in an embodiment. Figure 1 The up and down direction in the figure is the up and down direction of the lens barrel adjustment device. Figure 1 The left and right directions in the figure are taken as an example of the left and right directions of the lens barrel adjustment device.

[0046] Please refer to Figure 1 and Figure 2 The lens barrel adjustment device provided in the embodiment of the present application includes: a lens barrel 1, the lens barrel 1 has a plurality of lens barrels, at least two of the plurality of lens barrels 1 are arranged opposite to each other; a base 2, the base 2 is arranged on the rear side of the lens barrel 1 away from the user; a threaded rod 3, a threaded plate is installed to the base 2, and the threaded rod 3 is connected to the lens barrel 1, and the threaded rod 3 is used to drive the relatively arranged lens barrels 1 to move in opposite directions; an elastic limiting member 4, the elastic limiting member 4 is arranged on one of the lens barrel 1 and the base 2, and the other of the lens barrel 1 and the base 2 is provided with a plurality of card grooves 161, and the plurality of card grooves 161 are distributed along the movement direction of the lens barrel 1, and the elastic limiting member 4 is used to cooperate with at least one card groove 161 to fix the lens barrel 1 and the base 2.

[0047] The lens barrel adjustment device can be installed in the housing of the head-mounted device. A display screen can also be provided in the housing. The display screen can have two display areas, the two display areas correspond to the left eye and the right eye of the user respectively, and the two display areas are configured to perform the functions of the left eye area and the right eye area respectively. The display area can realize the virtual reality function. The user can watch the display content of the display screen through the lens barrel 1 in the lens barrel adjustment device.

[0048] The lens barrel 1 is a generally hollow cylindrical structure. A lens module (not shown) is installed in the lens barrel 1. The lens module may include a plurality of optical devices. The specific number and type of the optical devices may be set according to actual needs, and this embodiment is not specifically limited here. Exemplarily, the lens module may include a lens; the lens may be used to enlarge or reduce the image on the display screen, so that the display screen is smaller in size, lighter in weight, and consumes less energy than an ordinary display with the same field of view under the condition of achieving the same field of view; the lens may also be used to correct optical errors.

[0049] The lens barrel 1 usually has a plurality of lens barrels 1, and the plurality of lens barrels 1 are respectively arranged corresponding to the left eye and the right eye of the user, that is, the plurality of lens barrels 1 are generally arranged relatively along the left and right directions. Exemplarily, the lens barrel 1 can have two, and the two lens barrels 1 are arranged relatively along the left and right directions. Alternatively, the lens barrel 1 can also have four, and the four lens barrels 1 can be divided into two groups, each group having two lens barrels 1, and the two groups of lens barrels 1 are arranged relatively along the left and right directions. Of course, the number and distribution mode of the lens barrel 1 are not limited to this, and can be specifically arranged according to actual needs. For ease of description, the present embodiment will be described by taking the example that the lens barrel 1 has two, and the two lens barrels 1 are arranged relatively along the left and right directions.

[0050] Each lens barrel 1 can be mounted on a base 2, and the base 2 can be connected to other components of the head mounted device, such as a housing. A threaded rod 3 can be mounted on the base 2, and the threaded rod 3 is also connected to the lens barrel 1, and the threaded rod 3 is used to drive the lens barrels 1 arranged oppositely to move in opposite directions, for example, to move in opposite directions so that the spacing between the lens barrels 1 matched with the two threaded parts is reduced, or to move in opposite directions so that the spacing between the lens barrels 1 matched with the two threaded parts is increased.

[0051] The threaded rod 3 may be disposed on the upper side of the lens barrel 1 , or the threaded rod 3 may be disposed on the lower side of the lens barrel 1 , or the threaded rod 3 may be disposed on the upper side and the lower side of the lens barrel 1 , respectively.

[0052] In some examples, the threaded rod 3 may include a rod body, on which two threaded portions are disposed, and the two threaded portions have opposite spiral directions, so that the lens barrel 1 matched with the two threaded portions moves in opposite directions. For ease of description, this embodiment will be described by taking this as an example.

[0053] In other examples, there may be two threaded rods 3 , which are respectively matched with two opposite lens barrels 1 , and the spiral directions of the threads on the two threaded rods 3 are opposite, so that the lens barrels 1 matched with the two threaded parts move in opposite directions.

[0054] One of the lens barrel 1 and the base 2 is provided with an elastic stopper 4, and the other is provided with a plurality of slots 161, which are distributed along the movement direction of the lens barrel 1, i.e., the left-right direction, and the elastic stopper 4 is used to cooperate with at least one slot 161 to fix the lens barrel 1 and the base 2. The elastic stopper 4 is elastically deformed under the action of an external force to disengage from the currently matched slot 161, so that the distance between the two lens barrels 1 is adjustable.

[0055] The elastic stopper 4 may include one or more. When the elastic stopper 4 includes multiple elastic stoppers 4, the multiple elastic stoppers 4 are spaced apart. Exemplarily, the elastic stopper 4 may include two, and the two elastic stoppers 4 may be respectively arranged corresponding to the two lens barrels 1. Alternatively, the elastic stopper 4 may have at least three, and at least one of the two lens barrels 1 is correspondingly provided with at least two elastic stoppers 4; for example, the two lens barrels 1 are respectively correspondingly provided with two elastic stoppers 4, and the two elastic stoppers 4 may be respectively arranged on the upper side and the lower side of the lens barrel 1.

[0056] The following is an example of the cooperation between one of the elastic stoppers 4 and the slots 161. In some examples, when the two lens barrels 1 are relatively fixed, the elastic stopper 4 can cooperate with one of the slots 161. In the multiple slots 161 that cooperate with the elastic stopper 4, each slot 161 corresponds to a gear position, and each gear position corresponds to a lens barrel 1 spacing, that is, each slot 161 corresponds to a pupil distance. When the distance between the two lens barrels 1 needs to be adjusted, a force can be applied to one of the lens barrels 1 so that the lens barrel 1 can overcome the force of the elastic stopper 4, forcing the elastic stopper 4 to disengage from the current slot 161 and snap into the next slot 161 until the distance between the two lens barrels 1 is adjusted to the right position. In other examples, when the number of the elastic stoppers 4 is small, when the two lens barrels 1 are relatively fixed, the elastic stopper 4 can cooperate with multiple slots 161.

[0057] Among the multiple slots 161 that cooperate with the elastic stopper 4, the multiple slots 161 can be spaced and evenly distributed along the moving direction of the lens barrel 1. Alternatively, the multiple slots 161 are spaced and distributed along the moving direction of the lens barrel 1, and the spacing between two adjacent slots 161 relatively located in the middle can be smaller than the spacing between two adjacent slots 161 relatively located at the edge, wherein the pupil distance corresponding to the slot 161 relatively located in the middle is within the pupil distance range of the pupil distance of most users, and the pupil distance corresponding to the slot 161 relatively located at the edge corresponds to the pupil distance of a small number of users. For example, among the five slots 161 that cooperate with one of the elastic stoppers 4, the three slots 161 located in the middle are evenly distributed, that is, the first spacing between each two adjacent slots 161 is equal, and the second spacing between the two slots 161 located at the edge and the respective adjacent slots 161 is greater than the first spacing.

[0058] During the adjustment process, the elastic limit member 4 can undergo elastic deformation under the action of external force, specifically, it can deform in a direction away from the slots 161, so that the elastic limit member 4 can be detached from one of the slots 161; after the external force is removed, the elastic limit member 4 returns to its original state and is clamped in the currently corresponding slot 161, thereby fixing the lens barrel 1 and the base 2, so that the lens barrel adjustment device maintains the current lens barrel 1 spacing, that is, maintains the current pupil distance.

[0059] The lens barrel adjustment device provided in this embodiment includes: a lens barrel 1, which has a plurality of lens barrels, at least two of which are arranged opposite to each other; a base 2, which is arranged on the rear side of the lens barrel 1 away from the user; a threaded rod 3, a threaded plate is installed on the base 2, and the threaded rod 3 is connected to the lens barrel 1, and the threaded rod 3 is used to drive the relatively arranged lens barrel 1 to move in opposite directions; an elastic stopper 4, which is arranged on one of the lens barrel 1 and the base 2, and the other of the lens barrel 1 and the base 2 is provided with a plurality of slots 161, and the plurality of slots 161 are distributed along the movement direction of the lens barrel 1, and the elastic stopper 4 is used to cooperate with at least one slot 161 to fix the lens barrel 1 and the base 2. In this way, the lens barrel adjustment device in this embodiment occupies a relatively small space, which is conducive to miniaturization, and there is no need to set a drive motor, and there is no need to add a control function for the drive motor to the control board of the head-mounted device, which is conducive to reducing costs.

[0060] Figure 3 The edge of the lens barrel adjustment device provided in this embodiment Figure 1 Schematic diagram of the cross section along the AA direction. Figure 4 for Figure 3 Schematic diagram of the enlarged portion B. Figure 5 The edge of the lens barrel adjustment device provided by another embodiment Figure 1 Schematic diagram of the cross section in the AA direction 。 Please refer to Figures 3 to 5 In some embodiments, the elastic limit member 4 has an elastic clamping end 41 and a mounting end 42 connected to each other, the mounting end 42 is fixedly connected to one of the lens barrel 1 and the base 2, and the elastic clamping end 41 is used to cooperate with at least one slot 161.

[0061] The mounting end 42 can be fixedly connected to one of the lens barrel 1 and the base 2 by screw connection, welding or other fixed connection methods. The mounting end 42 and the elastic clamping end 41 can be integrally provided or fixedly connected by welding or other fixed connection methods.

[0062] The elastic clamping end 41 is an elastic sheet, and the portion of the elastic sheet located in the middle area is protruded in the direction toward the card slot 161, so that the elastic sheet is bent, and the opening formed after the elastic sheet is bent is located on the side away from the card slot 161. In this way, when entering and exiting the card slot 161, the size of the elastic sheet along its protruding direction can be reduced, which facilitates the elastic limiter 4 to enter and exit the card slot 161. Among them, the elastic clamping end 41 is roughly "V" shaped. The corresponding card slot 161 is also roughly "V" shaped.

[0063] Exemplarily, the elastic sheet includes a first sheet 411 and a second sheet 412, and the first sheet 411 and the second sheet 412 can be smoothly connected, and the first sheet 411 is connected between the second sheet 412 and the mounting end 42. Among them, the first sheet 411 and the second sheet 412 are connected to one side facing the slot 161. In this way, when adjusting the spacing of the lens barrel 1, under the action of external force, in the process of the elastic stopper 4 entering the slot 161 or detaching from the slot 161, the angle between the first sheet 411 and the second sheet 412 can be increased, so that the size of the elastic clamping end 41 of the elastic stopper 4 in the up-down direction is reduced, and then the elastic clamping end 41 of the elastic stopper 4 can slide out of the slot 161 and enter another slot 161.

[0064] Taking the connection between the elastic limit member 4 and the base 2 as an example, the mounting end 42 of the elastic limit member 4 can be connected to the base 2 by at least one screw, and the first sheet 411 and the second sheet 412 of the elastic limit member 4 are smoothly connected to the side away from the second lens, and the side of the first sheet 411 away from the second lens is fixedly connected to the mounting end 42, and the side of the second sheet 412 away from the first sheet 411 can be a free end, and the second sheet 412 and the side of the first sheet 411 away from the card slot 161 form an opening to facilitate elastic deformation of the elastic card end 41.

[0065] In other examples, taking the connection between the elastic stopper 4 and the base 2 as an example, the elastic stopper 4 may include a mounting housing and a spring, the spring being disposed between the base 2 and the mounting housing, and the spring being used to force the mounting housing in a direction toward the slot 161, so that the mounting housing remains in the slot 161. When adjusting the spacing of the lens barrel 1, under the action of an external force, when entering and exiting the slot 161, the spring can be compressed along its axial direction, so that the mounting housing can move toward the base 2, and then the mounting housing can slide out of the slot 161 and enter another slot 161.

[0066] In some embodiments, the elastic stopper 4 is disposed on the base 2, and the slots 161 are disposed on the lens barrel 1. The lens barrel 1 is fixedly provided with a stopper 16, which is extended along the movement direction of the lens barrel 1 and has a plurality of slots 161.

[0067] Exemplarily, the stopper 16 may be in the shape of an elongated strip, and the axial direction of the stopper 16 may be parallel to the moving direction of the lens barrel 1. The notch of the clamping slot 161 is located on the surface of the stopper 16 facing the elastic stopper 4, and the clamping slot 161 is extended in a direction away from the elastic stopper 4. A guiding surface may be provided at the notch of the clamping slot 161, and the guiding surface may be an inclined surface or an arc surface, for guiding the elastic stopper 4 to enter or slide out of the clamping slot 161.

[0068] In some examples, two relatively arranged lens barrels 1 may be respectively provided with limit blocks 16, and corresponding positions of the base 2 may be respectively provided with elastic limit members 4, so that after the lens barrel 1 spacing is adjusted into place, the lens barrel adjustment device can be reliably maintained at the lens barrel 1 spacing.

[0069] Among them, the upper side or the lower side of the lens barrel 1 can be provided with a limit block 16. For example, the lower sides of the two lens barrels 1 are respectively provided with a limit block 16, and the corresponding positions of the lower area of ​​the base 2 are respectively provided with elastic limit members 4, so that the elastic limit members 4 can cooperate with at least one slot 161 in the corresponding limit block 16. For another example, the upper sides of the two lens barrels 1 are respectively provided with a limit block 16, and the corresponding positions of the upper area of ​​the base 2 are respectively provided with elastic limit members 4, so that the elastic limit members 4 can cooperate with at least one slot 161 in the corresponding limit block 16. For another example, in the two lens barrels 1, the upper side of one lens barrel 1 is provided with a limit block 16, and the lower side of the other lens barrel 1 is provided with a limit block 16, and the corresponding positions of the base 2 are respectively provided with elastic limit members 4, so that the above-mentioned elastic limit members 4 can cooperate with at least one slot 161 in the corresponding limit block 16.

[0070] In other embodiments, the elastic limiting member 4 is disposed on the lens barrel 1 , and the clamping slot 161 is disposed on the base 2 , and the implementation process is similar to that of the above embodiment.

[0071] In some embodiments, the lens barrel 1 is connected to a first mounting seat 13, which has a threaded hole that matches the threaded rod 3; the base 2 is provided with a second mounting seat 23, which is provided with an axial hole that matches the threaded rod 3. The threaded hole and the axial hole can be coaxially arranged.

[0072] The lens barrel 1 is connected to one or more first mounting seats 13, and the first mounting seats 13 are provided with threaded holes that cooperate with the threaded rod 3, so that the lens barrel 1 can be driven to move linearly when the threaded rod 3 rotates. The first mounting seats 13 can be fixedly connected or integrally provided with the limit block 16, or the first mounting seats 13 and the limit block 16 can also be provided independently of each other.

[0073] One or more second mounting seats 23 are provided on the base 2. The second mounting seat 23 is provided with an axial hole that cooperates with the threaded rod 3. Through the cooperation between the axial hole and the threaded rod 3, the threaded rod 3 is supported, which is beneficial to improving the installation reliability of the lens and the threaded rod 3.

[0074] Exemplarily, each lens barrel 1 is provided with a first mounting seat 13. The first mounting seat 13 may include a first mounting substrate and a first mounting lug, the first mounting substrate may be detachably connected to the lens barrel 1 by screws, and the first mounting substrate extends a certain length along the movement direction of the lens barrel 1. The first mounting substrate is connected with a first mounting lug, or the first mounting substrate is connected with a plurality of first mounting lugs distributed at intervals. The first mounting lug is provided with a threaded hole.

[0075] The second mounting seats 23 may be respectively disposed on the opposite sides of each first mounting seat 13. In some examples, the structures of the second mounting seats 23 on the two sides of the same first mounting seat 13 may be different, wherein the second mounting seat 23 located between the two first mounting seats 13 mainly supports the threaded rod 3, and the second mounting seat 23 located on the side away from the two first mounting seats 13 mainly supports and limits the threaded rod 3. In other examples, the structures of the second mounting seats 23 on the two sides of the same first mounting seat 13 may be the same, and mainly support the threaded rod 3.

[0076] In the second mounting seat 23 located between the two first mounting seats 13, the second mounting seat 23 may have a second mounting substrate, and the second mounting substrate may be extended in a direction perpendicular to the movement direction of the lens barrel 1 and the axial direction of the lens barrel 1, that is, the second mounting substrate may be extended in the up-down direction, and the upper end and the lower end of the second mounting substrate are detachably connected to the base 2 by screws, respectively. A through axial hole may be opened in the middle portion of the second mounting substrate between the upper end and the lower end, or the middle portion of the second mounting plate 12 may be recessed in a direction away from the base 2 to form an axial hole.

[0077] In the second mounting seat 23 located on the side opposite to the two first mounting seats 13, the second mounting seat 23 may have a third mounting substrate and a mounting platform. The third mounting substrate is connected to the side of the mounting platform away from the first mounting seat 13, or in other words, the third mounting substrate is connected to the side of the mounting platform closer to the end of the threaded rod 3. The third mounting substrate is detachably connected to the base 2 by screws, and the mounting platform is provided with a blind hole-shaped shaft hole, and the bottom wall of the shaft hole is used to limit the threaded rod 3, limiting the displacement of the threaded rod 3 along the moving direction of the lens barrel 1.

[0078] Of course, the specific structure of the first mounting seat 13 is not limited thereto, and this embodiment is only used as an example. For example, the structure of the second mounting seat 23 located on the side opposite to the two first mounting seats 13 can be similar to the structure of the second mounting seat 23 located between the two first mounting seats 13, except that the shaft hole in the second mounting seat 23 located between the two first mounting seats 13 is a through hole, and the shaft hole in the second mounting seat 23 located on the side opposite to the two first mounting seats 13 is a blind hole.

[0079] In other examples, the area on the base 2 corresponding to the end of the threaded rod 3 may be provided with a second mounting seat 23, and the two ends of the threaded rod 3 may be rotatably disposed in the shaft holes of the two second mounting seats 23. The first mounting seat 13 may be located between the two second mounting seats 23. The specific structures of the first mounting seat 13 and the second mounting seat 23 may be similar to the above examples.

[0080] In some embodiments, the base 2 has a first mounting plate 22 and a first barrel 21, the first barrel 21 is connected to the side of the first mounting plate 22 facing the lens barrel 1; the first lens hole of the base 2 is set through the first barrel 21 and the first mounting plate 22, and the first lens hole and the second lens hole of the lens barrel 1 can be coaxially arranged. Among them, the limit block 16 and the second mounting seat 23 are both connected to the first mounting plate 22. The first mounting plate 22 can also be connected to other components of the head mounted device.

[0081] The lens barrel 1 has a second barrel 11 and a second mounting plate 12 connected to the outer circumference of the second barrel 11. The second mounting plate 12 is connected to one end of the second barrel 11 facing the base 2. The second mounting plate 12 is extended along the radial direction of the second barrel 11 to facilitate the setting of the first mounting seat 13 to prevent the first mounting seat 13 and the threaded rod 3 from interfering with the lens module installed in the second lens hole of the lens barrel 1.

[0082] In some examples, the second mounting plate 12 is connected to a first folding plate 14, which is folded relative to the second mounting plate 12 in a direction away from the second cylinder 11, and can be arranged perpendicular to the second mounting plate 12, and can be arranged parallel to the central axis of the second cylinder 11. The first folding plate 14 is also connected to a second folding plate 15, which is folded relative to the first folding plate 14 in a direction away from the central axis of the second cylinder 11, and can be arranged perpendicular to the first folding plate 14, that is, the second folding plate 15 can be arranged parallel to the first mounting plate 22. Of course, the angle between the first folding plate 14 and the second mounting plate 12, and the angle between the second folding plate 15 and the first folding plate 14 are not limited thereto, and can be set according to actual needs. The arrangement of the first folding plate 14 and the second folding plate 15 can prevent the first mounting seat 13 and the threaded rod 3 from interfering with the lens module installed in the second lens hole of the lens barrel 1, and can also make the structure of the lens barrel adjustment device more compact.

[0083] The first mounting seat 13 is fixedly connected to the second folding plate 15, so as to connect the first mounting seat 13 to the lens barrel 1. A mounting column may be provided on the surface of the second folding plate 15 away from the base 2, and a screw that cooperates with the first mounting seat 13 may be penetrated in the mounting column, so as to improve the installation reliability of the first mounting seat 13. In other examples, the screws of the second folding plate 15 may also be directly penetrated in the second folding plate 15.

[0084] In this embodiment, through the above arrangement, it is convenient to set the limit block 16, the first mounting seat 13 and the second mounting seat 23, which does not interfere with the movement of the threaded rod 3 and the lens barrel 1 and can also make the structure of the lens barrel adjustment device more compact.

[0085] The following is an example of the adjustment operation of the lens barrel adjustment device provided in this embodiment.

[0086] When the pupil distance needs to be increased, that is, when the spacing of the lens barrels 1 needs to be increased, a force is applied to one of the lens barrels 1, such as the lens barrel 1 on the right side, so that the elastic limit member 4 can be disengaged from a slot 161, thereby enabling the lens barrel 1 on the right side to move and drive the threaded rod 3 to rotate, and the rotating threaded rod 3 will drive the lens barrel 1 on the left side to move away from the lens barrel 1 on the right side; after the spacing of the lens barrels 1 is adjusted to the right, the force applied to the lens barrel 1 on the right side is cancelled, and the elastic limit member 4 can be engaged with another slot 161 on the base 2, so that the lens barrel adjustment device maintains the spacing of the lens barrels 1.

[0087] When the pupil distance needs to be adjusted to a smaller size, that is, the spacing of the lens barrels 1 needs to be adjusted to a smaller size, a force is applied to the lens barrel 1 on the right side so that the elastic limit member 4 can be disengaged from a slot 161, thereby enabling the lens barrel 1 on the right side to move and drive the threaded rod 3 to rotate, and the rotating threaded rod 3 will drive the lens barrel 1 on the left side to move toward the lens barrel 1 on the right side; after the spacing of the lens barrels 1 is adjusted to the right, the force applied to the lens barrel 1 on the right side is cancelled, and the elastic limit member 4 can be engaged with another slot 161 on the base 2, so that the lens barrel adjustment device maintains the spacing of the lens barrels 1.

[0088] The lens barrel adjustment device provided in this embodiment has a compact structure, occupies a relatively small space, and has a small structural limitation. It is not only applicable to head-mounted devices with two independent display screens, but also applicable to head-mounted devices with a common display screen. Among them, in the head-mounted device with two independent display screens, the lens barrels 1 arranged relatively correspond to the respective display screens. In the head-mounted device with a common display screen, the lens barrels 1 arranged relatively correspond to the same display screen. In addition, the arrangement of the threaded rod 3, the elastic limiter 4 and the card slot 161 is relatively concealed, which can ensure the integrity of the head-mounted device and make the appearance of the head-mounted device beautiful and simple.

[0089] This embodiment further provides a head mounted device, including a lens barrel adjusting device, the structure, function and implementation process of which may be the same or similar to those of the lens barrel adjusting device in any of the above embodiments.
