Description

Technical Field

[0001] The present application relates to the field of near-eye display technology, and in particular to a near-eye display device and a wearable device. Background Art

[0002] Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Near eye display devices (NED) can be used as functional components on wearable devices to implement virtual reality (VR) and augmented reality (AR) to provide immersive and interactive experiences. Near eye display devices can project images in a preset direction. Taking the near eye display device projecting images to the human eye as an example, since the optical path of the near eye display device projecting the light beam is relatively constant, when the human eye has refractive errors such as myopia, the human eye may not be able to see the image projected by the near eye display device. Utility Model Content

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0029] On a wearable device with a near-eye display device, a user can see a virtual object or scene generated by a computer, which can interact with objects or scenes in the real world. When the user has refractive errors such as myopia or hyperopia, the projection position of the virtual object or scene does not correspond to the position of the retina of the human eye, which will affect the clarity of the image projected by the near-eye display device obtained by the user, thereby affecting the use effect of the wearable device.

[0030] The near-eye display device in the example of the present application may have an optical machine, which may include an optical component and a display component, wherein the optical component may be an optical lens or a combination of optical lenses; the display component may be a microdisplay, which is used to provide display content for the device. It may be a self-luminous active device, such as a light-emitting diode panel micro-OLED (uOLED) and micro-LED (uLED), or a liquid crystal display screen that requires external light source illumination (including a transmissive Liquid crystal display (LCD) and a reflective Liquid crystal on silicon (LCOS)), as well as a digital micromirror array (DMD, the core of Digital light processing (DLP)) based on microelectromechanical system (MEMS) technology and a linear beam scanner (LBS).

[0031] See also Figure 1The near-eye display device 200 in the example of the present application can be used in wearable devices such as smart glasses. The smart glasses may include a frame 110, temples, and a lens 120 mounted on the frame 110, wherein the lens 120 may be an ordinary optical lens, or an optical lens with a preset diopter. The near-eye display device 200 may be mounted on the frame 110, temples, or lens 120 of the smart glasses. The near-eye display device 200 may be fixedly connected to the smart glasses, or may be movably or detachably connected to the smart glasses.

[0032] See also Figure 2 , Figure 3 and Figure 4 The present application discloses an example of a near-eye display device 200, which includes a bracket 210, a display component 220, an optical component 230 and a deformable component 240, wherein the display component 220 is connected to the bracket 210; the optical component 230 is arranged on the light-emitting side of the display component 220; the deformable component 240 is connected between the bracket 210 and the optical component 230, and the deformable component 240 is at least partially movably connected relative to the bracket 210; the deformable component 240 is at least partially configured to allow movement along a first direction 4a, and to move the optical component 230 relative to the display component 220 in the first direction 4a; the deformable component 240 is also at least partially configured to allow movement along a second direction 4b, and to move the optical component 230 relative to the display component 220 in the second direction 4b, wherein the first direction 4a and the second direction 4b are different from each other. The movement here may be a movement of height change caused by the deformation of the deformation component 240, a movement caused by the extension or relative position movement of the deformation component, or a movement formed by the movement of some components connected to the deformation component 240 by external components, and the external components may be electrical circuits or drive components, etc. For example, the deformation may be caused by the change in the atomic structure of the deformation component 240 due to the change in temperature caused by the passage of current.

[0033] The bracket 210 can be used to form a frame structure for installing the optical machine. The shape of the bracket 210 in this example can be adapted to the shapes of the display component 220 and the optical component 230, so that the display component 220 can be connected to a preset position on the bracket 210. The bracket 210 in this example can be partially hollow to form a receiving groove 211 for installing the display component 220, so that the optical machine part can be embedded in the bracket 210 to improve the structural stability of the optical machine.

[0034] Please refer to Figure 4 and Figure 5, the display component 220 can form an optical machine with the optical component 230, wherein the display component 220 has a light-emitting side, and the optical component 230 is arranged on the light-emitting side of the display component 220. The display component 220 can be used to project a light beam outward, and the light beam is output from the light-emitting side of the display component 220, and forms an image at a preset position after passing through the optical component 230. The display component 220 in this example can be at least one of a light-emitting diode panel micro-OLED, micro-LED, a liquid crystal display, a reflective Liquid crystal on silicon, a digital micromirror array based on micro-electromechanical system technology, or a laser beam scanner. The optical component 230 in this example can be an optical lens or a lens combination. The display component in this example can be fixedly connected to the bracket 210, and the display component 220 can also be detachably connected to the bracket 210. When the display component 220 is connected to the bracket 210, the light-emitting position of the display component 220 is relatively determined.

[0035] The deformation component 240 is used to connect the bracket 210 and the optical component 230, wherein the deformation component 240 is at least partially movably connected to the bracket 210, which means that at least part of the deformation component 240 can produce relative deformation or displacement relative to the bracket 210. When the deformation component 240 is deformed relative to the bracket 210, the optical component 230 connected to the deformation component 240 can also move synchronously relative to the bracket 210. When the deformation component 240 moves relative to the bracket 210, the distance between the optical component 230 and the display component 220 changes synchronously, and then the position of the image projected by the optical machine can be adjusted, so that the image projected by the near-eye display device 200 can be better adapted to the position of the retina of the human eye.

[0036] The deformable component 240 is at least partially configured to allow movement along the first direction 4a, which means that the deformable component 240 can at least partially move or deform in the first direction 4a. When the deformable component 240 moves along the first direction 4a, the optical component 230 connected to the deformable component 240 can move relative to the display component 220 in the first direction 4a, thereby adjusting the distance between the optical component 230 and the display component 220 in the first direction 4a. The deformable component 240 is at least partially also configured to allow movement along the second direction 4b, which means that the deformable component 240 can at least partially move or deform in the second direction 4b. When the deformable component 240 moves or deforms along the second direction 4b, the optical component 230 connected to the deformable component 240 can move relative to the display component 220 in the second direction 4b, thereby adjusting the distance between the optical component 230 and the display component 220 in the second direction 4b. The deformation component 240 in this example can move or deform along the first direction 4a or the second direction 4b, including that the deformation component 240 can at least partially produce deformation along the first direction 4a and the second direction 4b under a force state. For example, the deformation component 240 can be made of a material that produces deformation in the first direction 4a and the second direction 4b when subjected to external tension or compression; it can also include that the deformation component 240 can at least partially produce deformation along the first direction 4a and the second direction 4b under external stimulation or influence. The external stimulation or influence can be light, electricity, heat and other factors or a combination of them, causing the deformation component 240 to at least partially produce deformation in the first direction 4a and the second direction 4b. For example, the deformation component 240 can be at least partially made of photodeformable material, electrodeformable material or thermal deformation material. In some examples, the maximum stretchable distance of the deformable component 240 in the first direction 4a does not exceed 0.5 mm; in this example, the maximum stretchable distance of the deformable component 240 in the first direction 4a refers to the maximum deformation range of the deformable component 240 in the first direction 4a when the deformable component 240 moves or deforms in the first direction 4a. In this example, the maximum stretchable distance of the deformable component 240 in the first direction 4a can be the maximum movement distance of the optical component 230 compared to its initial state when the deformable component 240 is stretched in the first direction 4a. In some examples, the maximum movement distance of the deformable component 240 in the second direction 4b does not exceed 0.5 mm. In this example, the maximum movement distance of the deformable component 240 in the second direction 4b refers to the maximum deformation range of the deformable component 240 in the second direction 4b when the deformable component 240 moves or deforms in the second direction 4b. In this example, the maximum movement distance of the deformable component 240 in the second direction 4b can be the maximum movement distance of the optical component 230 compared to its initial state when the deformable component 240 is stretched in the second direction 4b.In some examples, the maximum stretchable distance of the deformation component 240 in the first direction 4a does not exceed 0.5 mm, and the maximum moving distance of the deformation component 240 in the second direction 4b does not exceed 0.5 mm.

[0037] The first direction 4a and the second direction 4b are different from each other, which may mean that the first direction 4a and the second direction 4b are different. In this example, the first direction 4a and the second direction 4b are different, including that the first direction 4a and the second direction 4b are opposite, for example, the first direction 4a is upward and the second direction 4b is downward, or the first direction 4a is downward and the second direction 4b is upward, etc. In other embodiments, the first direction 4a and the second direction 4b may also be arranged at an angle.

[0038] In this example, when the optical component 230 moves along the first direction 4a or the second direction 4b driven by the deformation component 240, the distance between the optical component 230 and the display component 220 changes. As the position of the optical component 230 is adjusted, the position of the image projected by the near-eye display device 200 also changes synchronously, thereby making the image projected by the near-eye display device 200 better adapt to the user's eyes, thereby reducing the problem of not being able to obtain a clear projection image due to reasons such as refractive errors of the human eye.

[0039] In some examples, the near-eye display device 200 also includes an electrical component (not shown in the figure), and the deformation component 240 is electrically connected to the electrical component, and the electrical component is used to supply power to the deformation component 240 so that the deformation component 240 can at least partially switch between movement in a first direction 4a and movement in a second direction 4b, wherein the first direction 4a is the direction in which the display component 220 and the optical component 230 move away from each other, and the second direction 4b is the direction in which the display component 220 and the optical component 230 move toward each other.

[0040] The deformation component 240 in this example is at least partially made of a material that can move or deform under the action of an electric field. The deformation component 240 can be a memory metal part or a piezoelectric material part. Both the memory metal part and the piezoelectric material part can deform when powered. The memory metal part, that is, the shape memory alloy (SMA), is an alloy that deforms when cold but returns to its pre-deformation ("memory") shape when heated. Piezoelectric material parts can be divided into three categories according to the crystallization method. The first category is a single crystal structure, such as quartz; the second category is a polycrystalline structure, such as ceramics, such as piezoelectric ceramics BaTiO3, PZT (lead zirconatetitanate piezoelectric ceramics); the third category is a polymer piezoelectric material, such as PVDF (vinylidene fluoride). In this example, the deformation component 240 can be made of piezoelectric ceramics, and the deformation component 240 can be a piezoelectric ceramic sheet. When the piezoelectric ceramic sheet forms a deformation component 240, the atomic unit cell of the piezoelectric ceramic sheet is elongated due to the action of the electric field force in the direction of the electric field. When a large number of atomic unit cells are elongated at the microscopic level and accumulated to a certain amount, it manifests as the deformation of the piezoelectric ceramic sheet at the macroscopic level. Optionally, the deformation component 240 in this example can be partially made of a memory metal piece, or the deformation component 240 can be partially made of a piezoelectric ceramic sheet, or the deformation component 240 can be a combination of multiple materials that can be deformed under the action of an electric field. Optionally, in this example, the deformable range of the deformation component 240 in the first direction 4a and the second direction 4b can be changed by selecting different materials or a combination of materials.

[0041] The electrical component can be a battery or an integrated circuit module. The electrical component in this example can be used to supply power to the deformation component 240. Taking the electrical component as an integrated circuit module as an example, the electrical component is connected to the deformation component 240. When the electrical component supplies power to the deformation component 240, the deformation component 240 generates deformation in the first direction 4a and the second direction 4b under the action of the voltage.

[0042] The first direction 4a is the direction in which the display component 220 and the optical component 230 move away from each other. When the electrical component supplies power to the deformable component 240, causing the deformable component 240 to move along the first direction 4a, the optical component 230 moves synchronously, thereby increasing the distance between the optical component 230 and the real component.

[0043] The second direction 4b is the direction in which the display component 220 and the optical component 230 approach each other. When the electrical component supplies power to the deformable component 240, causing the deformable component 240 to move along the second direction 4b, the optical component 230 moves synchronously, so that the distance between the optical component 230 and the real component is reduced.

[0044] In some examples, the electrical component may also be used to provide power to the display component 220 , or the electrical component may be used to perform data transmission with the display component 220 .

[0045] Please continue reading Figure 3 , Figure 4 and Figure 5 In some examples, the optical component 230 includes an optical module 231 and a sleeve 232, wherein the optical module 231 is arranged on the light-emitting side of the display component 220; the sleeve 232 is sleeved on the outside of the optical module 231, one end of the deformation component 240 is connected to the sleeve 232, and the other end of the deformation component 240 is connected to the bracket 210, and the sleeve 232 and the bracket 210 are arranged at intervals; the deformation component 240 is at least partially configured to drive the sleeve 232 to move along the first direction 4a, and move the optical module 231 in the first direction 4a relative to the display component 220; the deformation component 240 is at least partially configured to drive the sleeve 232 to move along the second direction 4b, and move the optical module 231 in the second direction 4b relative to the display component 220.

[0046] The optical module 231 may be an optical lens or a combination of optical lenses. The optical module 231 is disposed on the light-emitting side of the display component 220 so that the light beam output by the display component 220 can be projected in a preset direction via the optical module 231 .

[0047] A small part of the deformation component 240 is configured to drive the sleeve 232 to move along the first direction 4a, and move the optical module 231 in the first direction 4a relative to the display component 220; at least a part of the deformation component 240 is also configured to drive the sleeve 232 to move along the second direction 4b, and move the optical module 231 in the second direction 4b relative to the display component 220. One end of the deformation component 240 is connected to the sleeve 232, so that the sleeve 232 can be displaced synchronously with the deformation component 240; the other end of the deformation component 240 is connected to the bracket 210, so that the deformation component can form a whole with the bracket 210. The sleeve 232 can serve as an intermediate connecting member between the optical module 231 and the deformation component 240. When the deformation component 240 moves in the first direction 4a or the second direction 4b, the deformation component 240 can drive the sleeve 232 to move in the first direction 4a and the second direction 4b. The sleeve 232 is sleeved on the outside of the optical module 231. On the one hand, the sleeve 232 can be used to support the optical module 231, and on the other hand, the sleeve 232 can be used to reduce light leakage of the optical module 231. In this example, the length of the sleeve 232 along the axial direction can be greater than the length of the optical module 231, so that the optical module 231 can be completely located in the sleeve 232. The sleeve 232 and the bracket 210 are arranged at an interval, which means that there is a gap between the sleeve 232 and the bracket 210. In this example, the gap between the sleeve 232 and the bracket 210 can be located at one end of the sleeve 232 in the axial direction, that is, the sleeve 232 and the bracket 210 are projected in a plane parallel to the axial direction of the sleeve 232, and the projections of the sleeve 232 and the bracket 210 do not overlap; or, the sleeve 232 and the bracket 210 can be partially nested, that is, the sleeve 232 and the bracket 210 are projected in a plane parallel to the axial direction of the sleeve 232, and the projections of the sleeve 232 and the bracket 210 partially overlap, and there is a gap between the sleeve 232 and the bracket 210, so that the sleeve 232 can move relative to the bracket 210 in the first direction 4a and the second direction 4b.

[0048] In some examples, the deformation component 240 includes a plurality of deformation bodies 241, the deformation bodies 241 are in the shape of long strips, and the plurality of deformation bodies 241 are arranged at intervals along the circumference of the sleeve 232; the deformation body 241 is at least partially configured to allow movement along the first direction 4a, and the deformation body 241 is at least partially configured to allow movement along the second direction 4b; the deformation body 241 has a first end and a second end arranged along the length direction, the first end is connected to the sleeve 232, and the second end is connected to the bracket 210, and the first end and the second end are respectively electrically connected to the electrical component.

[0049] The deformation body 241 in this example is made of a material that can generate motion deformation in the first direction 4a and the second direction 4b under the action of an electric field. The deformation body 241 is in the shape of an elongated strip, which means that the deformation body 241 is in the shape of an elongated strip as a whole, and there are multiple deformation bodies 241. The multiple deformation bodies 241 are arranged at intervals along the circumference of the sleeve 232, so that the multiple deformation bodies 241 can be distributed along the circumference of the sleeve 232, and respectively connect the sleeve 232 and the bracket 210. The multiple deformation bodies 241 in this example can be distributed at equal intervals, and the multiple deformation bodies 241 can also be distributed at unequal intervals. In this example, the amplitudes of the motion deformation of adjacent deformation bodies 241 along the first direction 4a and the second direction 4b can be equal or unequal. Optionally, the material and volume of adjacent deformation bodies 241 can be the same or different.

[0050] The deformation body 241 has a first end and a second end arranged along the length direction, wherein the first end and the second end may be two ends of the deformation body 241 along the length direction, or the first end and the second end may be positions close to the ends of the deformation body 241 along the length direction. The first end is connected to the sleeve 232, which means that the first end is fixedly connected or detachably connected to the sleeve 232. The second end is connected to the bracket 210, which means that the second end is fixedly connected or detachably connected to the bracket 210. When the deformation body 241 deforms and moves in the first direction 4a or the second direction 4b, the sleeve 232 may be relatively close to or away from the bracket 210. The length direction of the deformation body 241 in this example may be consistent with the axial direction of the sleeve 232, and the deformation body 241 may be arranged parallel to the axial direction of the sleeve 232; optionally, the length direction of the deformation body 241 may also be arranged at a certain angle to the axial direction of the sleeve 232, and the deformation body 241 may be arranged in a spiral shape to a certain extent along the circumference of the sleeve 232.

[0051] The first end and the second end of the deformable body 241 are electrically connected to the electrical component, respectively. In this example, the first end and the second end of the deformable body 241 can be used as the positive and negative electrodes of the electrical component, respectively, so that the deformable body 241 can form a current loop with the electrical component. When the electrical component supplies power to the deformable body 241, the deformable body 241 can produce a deformation movement under the voltage, so that the length of the deformable body 241 changes, thereby changing the distance between the sleeve 232 and the bracket 210. Since the optical module 231 is connected to the sleeve 232, when the sleeve 232 moves, the distance between the optical module 231 and the display component 220 changes, thereby changing the position of the projected image on the retina.

[0052] In some examples, the deformation body 241 is a flexible memory metal.

[0053] The flexible material can be bent, twisted or deformed, for example, it can be a memory metal composed of nickel-titanium alloy. When subjected to external force, it can be deformed, and after the force is lost, it can maintain the shape when deformed by force. When the electrical component supplies power to the deformable body 241 or the temperature of the deformable body changes, the deformable body 241 can return to its original state under the action of the electric field. In this example, when the deformable body 241 is subjected to external force, the deformable body 241 can be stretched along the first direction 4a, and the sleeve 232 connected to the deformable body 241 can move synchronously, thereby increasing the distance between the optical module 231 and the display component. When the deformable body 241 forms a current loop with the electrical component, when the deformable body 241 is subjected to the electric field, the deformable body 241 contracts, so that the sleeve 232 moves along the second direction 4b, and the optical module 231 moves in the direction close to the bracket 210, so that the distance between the optical module 231 and the display component 220 is reduced. In other embodiments, the deformation body 241 may have different deformation distances under different current or voltage conditions, for example, a first deformation distance under a first current / voltage and a second deformation distance under a second current / voltage, wherein the first current / voltage and the second current / voltage are different in magnitude, and the first deformation distance and the second deformation distance are different. More different currents / voltages may be designed to control more different deformation distances as needed. Therefore, the deformation distance of the deformation body 241 may be controlled according to the magnitude of the current / voltage to achieve the distance adjustment between the optical module 231 and the display component 220.

[0054] In some examples, the length direction of the single deformation body 241 is set at an angle to the axial direction of the sleeve 232 .

[0055] In this example, the length direction of the deformation body 241 is set at an angle to the axial direction of the sleeve 232, which means that the length direction of a single deformation body 241 is not parallel to the axial direction of the sleeve 232, and the deformation body 241 can extend substantially in a spiral shape relative to the sleeve 232. By adopting the above arrangement, the length of the deformation body 241 can be increased within a limited range, the space between the sleeve 232 and the bracket 210 can be fully utilized, the deformable space of the deformation body 241 can be expanded, and the adjustable distance between the optical module 231 and the display assembly 220 can be increased.

In this example, the first annular portion 242 may be connected to the sleeve 232 by hot-melt, clamping, or other intermediate connectors. Optionally, a connecting portion 244 may be provided on the first annular portion 242. The connecting portion 244 may be a connecting piece structure protruding from the side of the first annular portion 242 away from the deformation body 241. The connecting portion 244 may be in the shape of an elongated strip or an annular shape. The connecting portion 244 is used to connect to the sleeve 232 to enhance the connection strength between the first annular portion 242 and the sleeve 232.

[0059] In some examples, the deformation component 240 also includes a second annular portion 243, which is connected to the bracket 210 and is arranged around the light-emitting surface of the display component 220. The second ends of the multiple deformation bodies 241 are respectively connected to the second annular portion 243, and the second annular portion 243 is electrically connected to the electrical component.

[0060] The second annular portion 243 can be a closed annular structure connected to the second end of the deformable body 241 or an annular structure with an opening. The second ends of multiple deformable bodies 241 are respectively connected to the second annular portion 243, so that the second annular portion 243 can serve as a common electrode for the second ends of the multiple deformable bodies 241, thereby facilitating the electrical connection of the second ends of the multiple deformable bodies 241 with electrical components.

[0061] The second annular portion 243 is arranged around the light emitting surface of the display component 220, which means that when the display component 220 emits a light beam, the second annular portion 243 and the display component 220 are projected in a plane perpendicular to the axial direction of the second annular portion 243, and the second annular portion 243 is located on the outer side of the light emitting surface of the display component 220, and the second annular portion 243 does not block the transmission of the light beam of the display component 220.

In this example, the second annular portion 243 is sleeved on the sleeve 232 so that the second annular portion 243 can be connected to the sleeve 232. In this example, the second annular portion 243 can be connected to the sleeve 232 by heat-melting, clamping, or other intermediate connecting parts. Optionally, a connecting portion 244 can be provided on the second annular portion 243, and the connecting portion 244 can be a connecting member structure protruding from the side of the second annular portion 243 away from the deformation body 241, and the connecting portion 244 can be a long strip or annular, and the connecting portion 244 is used to connect to the sleeve 232 to enhance the connection strength between the second annular portion 243 and the sleeve 232.

The first annular portion 242 and the second annular portion 243 in this example can be respectively used as two electrodes of the deformable body 241 to connect the deformable body 241 to the electrical component, and then the deformable body 241 is powered by the electrical component.

[0064] In some examples, the deformation component 240 also includes a first annular portion 242 and a second annular portion 243, the first annular portion 242 is sleeved on the sleeve 232, and the first ends of the plurality of deformation bodies 241 are respectively connected to the first annular portion 242; the second annular portion 243 is connected to the bracket 210 and is arranged around the light-emitting surface of the display component 220, and the second annular portion 243 and the first annular portion 242 are spaced apart along the second direction 4b; the second ends of the plurality of deformation bodies 241 are respectively connected to the second annular portion 243, and the first annular portion 242 and the second annular portion 243 are respectively electrically connected to the electrical component; the length direction of the deformation body 241 is arranged at an angle to the axial direction of the sleeve 232.

In this example, the length direction of the deformation body 241 is set at an angle to the axial direction of the sleeve 232, so that the deformation body 241 can be arranged in a generally spiral shape on the outside of the sleeve 232 to extend the length of the deformation body 241, thereby increasing the movable range of the optical module 231 relative to the bracket 210.

[0066] Please refer to Figure 6 , Figure 7 as well as Figure 8 In some examples, a positioning portion 2325 is provided at one end of the optical module 231 away from the display component 220, and the positioning portion 2325 is provided on the outer periphery of the optical module 231; the sleeve 232 includes a first section 2321 and a second section 2322, the first section 2321 is connected to the deformation component 240, and the first section 2321 is sleeved on the outer side of the optical module 231; the second section 2322 is connected to the end of the first section 2321 away from the deformation component 240, and the second section 2322 is sleeved on the outer side of the optical module 231, the inner diameter of the second section 2322 is larger than the inner diameter of the first section 2321, and the second section 2322 has a first positioning surface 2323 facing away from the display component 220, and the positioning portion 2325 abuts against the first positioning surface 2323.

[0067] The positioning portion 2325 is a protruding structure protruding from the optical module 231 . In this example, the positioning portion 2325 can be an annular structure or a bump structure protruding from the outer wall surface of the optical module 231 . The maximum outer diameter of the positioning portion 2325 is greater than the maximum outer diameter of the optical module 231 .

[0068] The first section 2321 is a part of the sleeve 232, and the first section 2321 is connected to the deformation component 240. In this example, when the deformation component 240 is provided with the first annular portion 242 described above, the first section 2321 can be connected to the first annular portion 242, the first section 2321 can be arranged inside and outside the first annular portion 242, and the first end can also be connected to the first annular portion 242 through the connection portion 244 described above.

The second section 2322 is used to cooperate with the positioning portion 2325. The optical module 231 can be embedded in the sleeve 232 from one side of the second section 2322. The inner diameter of the second section 2322 is larger than the inner diameter of the first section 2321, so that a stepped surface is formed on the inner side of one end of the second section 2322 close to the first section 2321. The second section 2322 has a first positioning surface 2323, which is a surface of the second section 2322 that is away from the display assembly 220. The maximum outer diameter of the second positioning portion 2325 is larger than the inner diameter of the second section 2322, so that the positioning portion 2325 cannot move into the first section 2321. When the optical module 231 is installed in the sleeve 232, the positioning portion 2325 can be clamped at the first positioning surface 2323, so that the first positioning surface 2323 can be used to limit the maximum installation depth of the optical module 231 in the sleeve 232. The positioning portion 2325 in this example can be set at the periphery of one end of the optical module 231 away from the display assembly 220.

[0070] In some examples, the near-eye display device 200 also includes a protective shell 250, which is disposed on the side of the optical module 231 away from the display component 220; a second positioning surface 2324 is provided on the inner side of the end of the second section 2322 away from the first section 2321, and the second positioning surface 2324 is located on the side of the first positioning surface 2323 away from the first section 2321, and the second positioning surface 2324 is arranged to face away from the display component 220; the protective shell 250 is positioned and connected to the second positioning surface 2324.

[0071] The protective shell 250 may be an optical glass covering the side of the optical module 231 away from the display assembly 220 .

[0072] The second positioning surface 2324 is a surface formed at one end of the second section 2322 away from the first section 2321. The second positioning surface 2324 can be used to form a stepped surface on the inner side of the end of the second section 2322 away from the first section 2321. In this example, the distance between the second positioning surface 2324 and the end surface of the second section 2322 away from the first section 2321 can be greater than the thickness of the protective shell 250, so that the protective shell 250 can be embedded in the inner side of the second section 2322. The second positioning surface 2324 can be used to limit the maximum embedding depth of the protective shell 250 in the sleeve 232. The protective shell 250 in this example can be mutually clamped and / or bonded with the second positioning surface 2324, and the second positioning surface 2324 can also be installed at the second positioning surface 2324 through other intermediate connectors.

[0073] Please refer to Fig. 9In some examples, the bracket 210 is provided with a receiving groove 211 and a light emitting hole 212 connected to the receiving groove 211 , the display component 220 is at least partially disposed in the receiving groove 211 , and the light emitting side of the display component 220 is disposed toward the light emitting hole 212 .

[0074] The bracket 210 in this example is at least partially a hollow structure, and the receiving groove 211 can be a space for installing the display assembly 220. The display assembly 220 is at least partially located in the receiving groove 211, so that the display assembly 220 can be at least partially limited to the inner side of the bracket 210 to improve the structural stability of the display assembly 220. The light exit hole 212 is connected to the receiving groove 211. The light exit hole 212 in this example can be a through groove that penetrates the bracket 210. The light exit side of the display assembly 220 is arranged toward the light exit hole 212, which means that the light exit side of the display assembly 220 corresponds to the position of the light exit hole 212. The light beam projected by the display assembly 220 can be projected toward the optical assembly 230 through the light exit hole 212. The optical assembly 230 in this example can be completely located outside the bracket 210, so as to reduce the volume of the bracket 210 and facilitate the miniaturization design of the near-eye display device 200. Optionally, the portion of the display component 220 located in the bracket 210 can be snapped into the accommodating groove 211, the portion of the display component 220 located in the bracket 210 can also be bonded to the inner wall surface of the accommodating groove 211, or the portion of the display component 220 located in the bracket 210 can be connected to the bracket 210 through an intermediate connecting member.

[0075] In some examples, the outer diameter of the sleeve 232 at one end close to the bracket 210 is smaller than the inner diameter of the light emitting hole 212, and when the deformation component 240 moves along the second direction 4b, the sleeve 232 is at least partially located on the inner side of the light emitting hole 212; a fixing ring 213 is protruded from the bracket 210, and the fixing ring 213 is arranged around the light emitting hole 212, and the deformation component 240 is arranged inside and outside the fixing ring 213 at one end close to the bracket 210.

[0076] The outer diameter of the end of the sleeve 232 close to the bracket 210 is smaller than the inner diameter of the light exit hole 212, so that when the sleeve 232 moves along the second direction 4b under the action of the deformation component 240, the outer wall surface of the sleeve 232 can be staggered with the inner wall surface of the light exit hole 212 to reduce the friction between the sleeve 232 and the inner wall surface of the light exit hole 212. The end of the sleeve 232 close to the bracket 210 can partially extend into the inner side of the light exit hole 212. When the sleeve 232 moves relative to the bracket 210, a space for accommodating the sleeve 232 can be formed at the light exit hole 212, which can facilitate reducing the volume of the optical component 230.

[0077] A fixing ring 213 may be provided on one side of the light exit hole 212 on the bracket 210, and the fixing ring 213 may be an annular structure provided on the outer surface of the bracket 210; the fixing ring 213 is provided around the light exit hole 212, which means that the fixing ring 213 is provided on the periphery of the light exit hole 212, and the shape of the fixing ring 213 may be consistent with the shape of the light exit hole 212. The end of the deformation component 240 close to the bracket 210 is provided inside and outside the fixing ring 213, which means that the end of the deformation component 240 close to the bracket 210 can be provided on the outside of the fixing ring 213, and the end of the deformation component 240 close to the bracket 210 can be connected to the inner ring surface of the fixing ring 213. The fixing ring 213 in this example can be used as an intermediate connecting member connected to the deformation component 240 on the bracket 210, and the fixing ring 213 can be used to increase the connection area between the bracket 210 and the deformation component 240 to improve the reliability of the connection between the bracket 210 and the deformation component 240. When the deformation component 240 includes the second annular portion 243 described in any of the above examples, the second annular portion 243 can be disposed inside and outside the fixing ring 213. In this example, the deformation component 240 can be connected to the fixing ring 213 by bonding, hot-melt connection or other methods. The deformation component 240 can be sleeved on the outside of the sleeve 232. In this example, the sleeve 232 can be disposed inside and outside the fixing ring 213, so that a space for accommodating the sleeve 232 can be formed inside the fixing ring 213.

[0078] In some examples, a fixing ring 213 is protruded from the bracket 210 and is arranged around the light emitting hole 212. The outer diameter of the sleeve 232 at one end close to the bracket 210 is smaller than the inner diameter of the fixing ring 213. When the deformation component 240 moves along the second direction 4b, the sleeve 232 is at least partially located on the inner side of the fixing ring 213.

[0079] The fixing ring 213 is a protruding structure provided on the surface of the bracket 210. The fixing ring 213 and the light exit hole 212 are located on the same side of the bracket 210. The fixing ring 213 can be a closed ring structure. The outer diameter of the end of the sleeve 232 close to the bracket 210 is smaller than the inner diameter of the fixing ring 213, so that the end of the sleeve 232 close to the bracket 210 can extend into the inner side of the fixing ring 213. When the sleeve 232 moves relative to the bracket 210, the space inside the fixing ring 213 can be used to accommodate the sleeve 232, so that the sleeve 232 has space to move toward the inner side of the light exit hole 212. When the deformation component 240 in this example moves along the second direction 4b, the sleeve 232 is at least partially located inside the fixing ring 213, and the outer diameter of the sleeve 232 is smaller than the inner diameter of the fixing ring 213, so that when the optical module 231 moves toward the display component 220, the inner wall of the fixing ring 213 is reduced to block the sleeve 232.

[0080] Please refer to Figure 8 , Fig. 9 and Fig.10In some examples, the bracket 210 is provided with a receiving groove 211 and a light emitting hole 212 and an opening 214 respectively connected to the receiving groove 211, and the opening 214 is arranged opposite to the light emitting hole 212; the display component 220 is at least partially arranged in the receiving groove 211, and the light emitting side of the display component 220 is arranged toward the light emitting hole 212; the near-eye display device 200 also includes a back panel 260, which is connected to the bracket 210 and is used to close the opening 214; the display component 220 includes a micro display 221, which is at least partially connected to the back panel 260, and the light emitting side of the micro display 221 is arranged toward the light emitting hole 212.

[0081] The opening 214 may be an opening on the bracket 210 that is arranged opposite to the light exit hole 212, and the opening 214 may be used to form a space for installing the display assembly 220. Optionally, the end surface on one side of the bracket 210 that is opposite to the light exit hole 212 may be arranged as an open structure, so that the opening 214 is formed on the side of the bracket 210 that is opposite to the light exit hole 212.

[0082] The back plate 260 may be a plate-like structure connected to the bracket 210 . When the back plate 260 is connected to the bracket 210 , the back plate 260 may close the opening 214 .

[0083] The display component 220 includes a microdisplay 221, which can be at least one of the above-mentioned light-emitting diode panels micro-OLED, micro-LED, liquid crystal display, reflective Liquid crystal on silicon, digital micromirror array based on micro-electromechanical system technology, or laser beam scanner. The microdisplay 221 is at least partially connected to the back plate 260 so that the microdisplay 221 can maintain a preset position on the bracket 210. In this example, the microdisplay 221 can be bonded to the back plate 260, or the microdisplay 221 can be connected to the back plate 260 through other intermediate connectors. When the microdisplay 221 is installed in the accommodating groove 211, the light-emitting side of the microdisplay 221 is arranged toward the light-emitting hole 212, and the back plate 260 is located on the side of the microdisplay 221 facing away from the light-emitting hole 212. The back plate 260 in this example can be used as a carrier of the micro display 221. On the one hand, it can facilitate the relative fixation of the micro display 221 and the bracket 210. On the other hand, the back plate 260 can protect the side of the micro display 221 away from the optical component 230, thereby helping to improve the structural strength of the near-eye display device 200. In this example, the micro display 221 and the back plate 260 can be installed on the bracket 210 along the first direction 4a, and the micro display 221 and the back plate 260 can also be plugged into the bracket 210 from other parts of the bracket 210.

[0084] In some examples, there is a gap between the back panel 260 and one end of the bracket 210 near the opening 214, and the gap forms a slot 215. The slot 215 is located on one side of the back panel 260 along the third direction 4c, and the third direction 4c is set at an angle with the first direction 4a; the display component 220 also includes a circuit board 222 and a flexible wire connected to the circuit board 222, the circuit board 222 is arranged on the outside of the bracket 210, and the circuit board 222 is electrically connected to the micro display 221.

[0085] The third direction 4c in this example can be a direction perpendicular to the first direction 4a and the second direction 4b. For example, the side surface of a bracket 210 provided with a light outlet along the first direction 4a is the front surface of the bracket 210, and the side surface of the bracket 210 provided with an opening 214 is the back surface of the bracket 210. The back plate 260 can be plugged into the bracket 210 from the side surface of the bracket 210.

[0086] A gap is formed between the back plate 260 and the end of the bracket 210 close to the opening 214, which means that the end of the bracket 210 close to the opening 214 is not in contact with the back plate 260, and a slot 215 can be formed in the gap between the bracket 210 and the back plate 260, and the slot 215 communicates with the receiving groove 211 and the outside of one side of the bracket 210 along the third direction 4c. Optionally, after the micro display 221 is installed in the receiving groove 211, the micro display 221 can close the slot 215.

[0087] The display assembly 220 further includes a circuit board 222, and the circuit board 222 is electrically connected to the micro display 221, which means that the circuit board 222 can be used to power the micro display 221, and / or the circuit board 222 can communicate signals with the micro display 221. The circuit board 222 and the micro display 221 can be electrically connected by wires, flexible circuit boards or other structures. The circuit board 222 is arranged on the outside of the bracket 210, and the circuit board 222 does not occupy the internal space of the bracket 210, so as to facilitate the miniaturization design of the bracket 210.

[0088] The display assembly 220 further includes a flexible wire, which can be used to connect the circuit board 222 with external components to facilitate power supply or signal transmission to the circuit board 222. In this example, the flexible wire can be arranged outside the bracket 210, and the flexible wire does not occupy the internal space of the bracket 210.
