Description

Technical Field

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

[0002] Near-eye display (NTDOD) can create virtual images in the field of view of the human eye. Near-eye display uses a near-eye display module placed within the non-clear vision distance of the human eye to render light field information to the human eye, thereby reconstructing the virtual scene in front of the human eye.

[0003] The near-eye display module can be installed on near-eye display devices such as glasses and helmets for users to use. Due to factors such as the position of the eyes, the visual axis varies between different people. When the light emitted by the near-eye display module is aligned with the visual axis of the human eye, the human eye can better receive the light emitted by the near-eye display module and form a better display effect. For this reason, manufacturers need to manufacture multiple different models of the same near-eye display device. Among them, the difference between different models of equipment is that the installation position of the near-eye display module is different, thereby satisfying users with different visual axis positions. This brings about the problem of high production and manufacturing costs. Utility Model Content

[0004] The purpose of this application is to overcome the defects of the prior art and provide a near-eye display device and a wearable device to solve the problems in the prior art.

[0005] To solve the above problems, an embodiment of the present application provides a near-eye display device, including a housing and a near-eye display module, including:

[0006] A shell, wherein the shell is provided with a cavity and a light-transmitting window communicating with the cavity, and the light-transmitting window faces the eye side of the shell;

[0007] A first sliding portion, located at a position of the housing corresponding to the light-transmitting window;

[0008] a near-eye display module, disposed in the cavity, the near-eye display module at least partially leaking out relative to the light-transmitting window and configured to allow light to be emitted from the light-transmitting window; and

[0009] The second sliding portion is arranged on the periphery of the near-eye display module; wherein the first sliding portion and the second sliding portion are configured to allow the near-eye display module to move within the cavity.

[0010] An embodiment of the present application also provides a wearable device, comprising the near-eye display device as described above.

[0011] The near-eye display device and wearable device proposed in the present application, the near-eye display device includes a shell and a near-eye display module. Since the near-eye display module is arranged in the cavity of the shell, and is configured to allow the near-eye display module to move in the cavity through the first sliding portion and the second sliding portion, the near-eye display module can be adjusted to different positions of the cavity according to the pupil distance of different users, thereby adapting to the pupil distance of different users, without the need to produce different shells for different users' pupil distances, thereby reducing manufacturing costs.

[0026] Example

[0027] See also Figure 1-Figure 11 In the present embodiment, a near-eye display device is proposed, including a housing 100 , a first sliding portion 2201 , a near-eye display module 200 , and a second sliding portion 320 .

[0028] In this embodiment, the housing 100 is described by taking glasses as an example. In other embodiments, the housing 100 may also be a helmet or the like.

[0029] The housing 100 is provided with a cavity 101 and a light-transmitting window 102 connected to the cavity 101, and the light-transmitting window 102 faces the eye side 103 of the housing 100. After the housing 100 is worn on the user's head, the light-transmitting window 102 faces the eye side of the housing 100, and the light-transmitting window 102 faces away from the environment side 104 of the housing 100. In addition, the housing 100 has a first direction X and a second direction Y, and the first direction X and the second direction Y are perpendicular.

[0030] The first sliding portion 2201 is located at a position of the housing 100 corresponding to the light-transmitting window 102 .

[0031] The near-eye display module 200 is disposed in the cavity 101. The near-eye display module 200 at least partially leaks out relative to the light-transmitting window 102, and is configured to allow light to be emitted from the light-transmitting window 102. After the user wears the housing 100, the light emitted by the near-eye display module 200 is irradiated into the human eye through the light-transmitting window 102, so that the user can view the image source played by the near-eye display module 200.

[0032] And, the second sliding portion 320 is disposed on the periphery of the near-eye display module 200 ; wherein the first sliding portion 2201 and the second sliding portion 320 are configured to allow the near-eye display module 200 to move in the cavity 101 .

[0033] In the embodiment of the present application, since the near-eye display module 200 is arranged in the cavity 101 of the shell 100, and is configured to allow the near-eye display module 200 to move in the cavity 101 through the first sliding portion 2201 and the second sliding portion 320, the near-eye display module 200 can be adjusted to different positions in the cavity 101 according to the pupil distance of different users, thereby adapting to the pupil distance of different users. There is no need to produce different shells for different users' pupil distances, thereby reducing manufacturing costs.

[0034] In some embodiments, Figure 2 and Figure 3 As shown, the near-eye display module 200 includes a microdisplay 210, an optical module 220 and a fixing seat 230, the microdisplay 210 and the optical module 220 are located in the fixing seat 230, the light-transmitting window 102 extends along the first direction X of the shell 100, the length of the light-transmitting window 102 is greater than the length of the fixing seat 230, the second sliding portion 320 is arranged on the fixing seat 230, the first sliding portion 2201 extends along the first direction X, and the microdisplay 210, the optical module 220 and the fixing seat 230 are configured to allow movement along the first direction X in the cavity 101.

[0035] Among them, the micro display 210 is used to project light; it can be, for example, Micro-LED (Micro Light-Emitting Diode), micro-luminescent semiconductor, uLED micro light-emitting diode, Micro-oled (Micro Organic Light-Emitting Diode), micro organic light-emitting diode, LCoS (Liquid Crystal On Silicon), silicon-based liquid crystal, LCD (Liquid Crystal Display), liquid crystal display, DMD (Digital Micromirror Device), digital micromirror device ( / DLP Digital Light Processing), digital light processing or LBS (Laser Beam Scanning), laser beam scanning, etc., or any combination of these technologies. The micro display 210 can provide an image source, such as text, video, information prompts, etc.

[0036] The optical module 220 is spaced apart from the micro display 210 , wherein the optical module 220 may be made of a transparent or light-transmitting material, such as PMMA polymethyl methacrylate, polymethyl methacrylate, PC polycarbonate, polycarbonate plastic, resin, glass, etc.

[0037] The optical module 220 as a whole may be cylindrical, for example, it may be a regular shape such as a cylinder, a prism, or a truncated cone, etc., and of course, it may also be an irregular shape.

[0038] The fixing base 230 realizes the connection between the optical module 220 and the micro display 210, so that when the fixing base 230 moves in the cavity 101, it drives the optical module 220 and the micro display 210 to move in the cavity 101, and the fixing base 230, the optical module 220, and the micro display 210 are relatively stationary.

[0039] Since the length of the light-transmitting window 102 is greater than that of the fixing seat 230 and the second sliding portion 320 is disposed on the fixing seat 230 , the fixing seat 230 can drive the micro display 210 and the optical module 220 to move along the first direction X in the cavity 101 to reach a position adapted to the user's pupil distance.

[0040] After the user wears the housing 100 , the light emitted by the micro display 210 passes through the optical module 220 and the light-transmitting window 102 and shines into the human eye, so that the user can see the image source played by the micro display 210 .

[0041] In some embodiments, Figure 2 and Figure 4As shown, the near-eye display device further includes a bracket 300 , which is disposed on the light-transmitting window 102 . The bracket 300 is provided with a mounting through hole 310 along the first direction X, wherein the first sliding portion 2201 is disposed on the bracket 300 .

[0042] Since the first sliding connection portion 2201 is located on the bracket 300, the bracket 300 is arranged on the light-transmitting window 102, and the second sliding connection portion 320 is arranged on the fixing seat 230 of the near-eye display module 200, the first sliding connection portion 2201 and the second sliding connection portion 320 are slidably connected. Through the mutual cooperation between the first sliding connection portion 2201 and the second sliding connection portion 320, the stability of the near-eye display module 200 when sliding relative to the mounting through hole 310 can be ensured.

[0043] The mounting through hole 310 may be a waist-shaped hole, a square hole, a rectangular hole or a through hole of other shapes. As long as the shape of the through hole in which the near-eye display module 200 can slide relative to the mounting through hole 310 is a simple deformation and transformation of the present case, it falls within the protection scope of the present application.

[0044] The sliding direction of the optical module 220 relative to the mounting through hole 310 is parallel to the first direction X. When the user wears the housing 100 , the first direction X of the housing 100 is substantially parallel to the line connecting the center points of the two eyes of the user.

[0045] In some embodiments, Figure 3-Figure 6 As shown, the first sliding portion 2201 and the second sliding portion 320 respectively include two lines, and the two second sliding portions 320 are respectively arranged on the opposite sides of the bracket 300 along the second direction Y; the two first sliding portions 2201 are respectively arranged on the opposite sides of the fixing seat 230 along the second direction Y, and the second sliding portions 320 are not located in the mounting through hole 310.

[0046] After assembling the near-eye display module 200 and the bracket 300, since the second sliding portion 320 is not located in the mounting hole 310, the near-eye display module 200 will not extend from the mounting hole 310 toward the eye side, but will be spaced apart from the plane where the mounting hole 310 is located along the first direction X.

[0047] It is understandable that the number of the first sliding parts 2201 and the second sliding parts 320 is not limited to two, and can be other numbers as long as the first sliding part 2201 can be tightly matched with the second sliding part 320.

[0048] In some embodiments, the length of the mounting through hole 310 is 6 mm-12 mm.

[0049] In some embodiments, the maximum size of the optical module 220 is less than or equal to 20 mm, such as 20 mm, 18 mm, 15 mm, etc., so as to facilitate the assembly of the optical module 220 into a smaller space. The length of the mounting hole 310 refers to the length of the two top ends along the first direction X.

[0050] Therefore, the near-eye display module 200 can move within a range of the mounting through hole 310 from the first direction X, such as Figure 7 and Figure 8 As shown, the moving distance of the optical module 220 from the first position to the second position is 0 mm to 12 mm, that is, the maximum distance that the optical module 220 can move in the mounting through hole 310 can be 0 mm to 12 mm. For example, in some embodiments, the maximum distance that the near-eye display module 200 can move in the mounting through hole 310 is 0 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, or 12 mm.

[0051] The first position and the second position are merely two extreme positions of the optical module 220 relative to the mounting hole 310, that is, the near-eye display module 200 can be adjusted within the mounting hole 310 along the first direction X within a range of 0mm-12mm, wherein the optical module 220 can be moved to any position between the first position and the second position.

[0052] The near-eye display module 200 has an optical axis, and the human eye has a visual axis. In general, the visual axis of the human eye is related to factors such as the pupil distance of the human eye. Therefore, the visual axis positions of different people are different. When the optical axis of the optical module 220 in the near-eye display module 200 is aligned with the visual axis of the human eye, the human eye can better receive the light projected by the near-eye display module 200, forming a better display effect. After the user wears the shell 100, the shell 100 and the user's head can be regarded as being in a relatively fixed state. Since the optical module 220 in the near-eye display module 200 is fixedly connected to the micro display 210, and the optical module 220 can be slidably arranged in the mounting through hole 310, by adjusting the position of the near-eye display module 200, the position of the near-eye display module 200 relative to the shell 100 is changed, thereby realizing the movement of the optical axis of the optical module 220 to adapt to the visual axis position of different users and the pupil distance of different users.

[0053] In some embodiments, Figure 4-Figure 6As shown, one of the first sliding connection part 2201 and the second sliding connection part 320 is a slider and the other is a slide groove; wherein the slider can be slidably disposed in the slide groove, and the slider and the slide groove are tightly matched. Since there are two first sliding connections 2201 and two second sliding connections 320, when the fixing seat 230 of the near-eye display module 200 is assembled with the bracket 300, the reliability of the connection between the two is higher, wherein when the fixing seat 230 drives the micro display 210 and the optical module 220 to adjust their positions relative to the bracket 300, the sliding process is smoother.

[0054] In the first sliding connection part 2201 and the second sliding connection part 320, one is a slider and the other is a slide groove. The slider can be slidably arranged in the slide groove, and the slider and the slide groove are tightly matched. Since the slider and the slide groove are tightly matched, only when the optical module 220 is directly subjected to sufficient external force, can it slide relative to the bracket 300, thereby ensuring the stability of the relative position of the near-eye display module 200 and the bracket 300, and avoiding the position of the near-eye display module 200 in the mounting through hole 310 from being offset due to collision, shaking, etc. of the housing 100.

[0055] In this embodiment, the first sliding connection portion 2201 is a slider, and the second sliding connection portion 320 is a slide groove. In other embodiments, the first sliding connection portion 2201 is a slide groove, and the second sliding connection portion 320 is a slider.

[0056] It is understandable that the first sliding connection portion 2201 and the second sliding connection portion 32 are not limited to the form of a slider and a slide groove, but can also be a screw structure or a gear meshing form, which is not limited here.

[0057] In some embodiments, in this embodiment, the bracket 300 is provided with a first connecting portion 330. In other embodiments, Figure 9-10 As shown, the housing 100 is provided with a second connection portion 120, wherein the first connection portion 330 is connected to the second connection portion 120. Thus, the connection between the bracket 300 and the housing 100 is achieved.

[0058] The bracket 300 is provided with first connecting parts 330 at both ends of the second direction Y, wherein the second connecting parts 120 correspond one to one with the first connecting parts 330. Since there are two first connecting parts 330 and two second connecting parts 120, when the bracket 300 and the housing 100 are assembled, the reliability and stability of the connection between the two can be ensured to be higher.

[0059] In the first connection portion 330 and the second connection portion 120, one is a plug-in protrusion and the other is a slot, wherein the plug-in protrusion is plugged into the slot.

[0060] In this embodiment, the first connection portion 330 is a plug-in protrusion, and the second connection portion 120 is a slot. In other embodiments, the first connection portion 330 is a slot, and the second connection portion 120 is a plug-in protrusion.

[0061] It can be understood that the connection between the first connecting part 330 and the second connecting part 120 is not limited to the method of plug-in protrusions and slots, but can also be a connection method such as screw connection, magnetic attraction, bonding or snap connection. As long as the connection method can ensure the reliability and stability when the bracket 300 and the shell 100 are assembled, they are simple deformation and transformation of the present application and fall within the protection scope of the present application.

[0062] In some embodiments, Figure 5 As shown, an inner recess 3102 is further provided on the mounting through hole 310 , and the recessed direction of the inner recess 3102 is away from the center of the mounting through hole 310 . The inner recess 3102 includes two inner recesses 3102 that are arranged opposite to each other in the second direction Y.

[0063] Specifically, by providing the inner recess 3102 , the position of the near-eye display module 200 in the mounting through hole 310 can be easily adjusted.

[0064] In some other embodiments, if the size of the mounting through hole 310 is large enough, it is not necessary to provide the inner recess 3102 in the mounting through hole 310 .

[0065] In some embodiments, Figure 5 As shown, a first step 3101 is disposed on the inner wall of the mounting through hole 310 . The protruding direction of the first step 3101 faces the center of the mounting through hole 310 . The inner recess 3102 is located on the first step 3101 .

[0066] In some embodiments, Figure 1 and Figure 2 As shown, the near-eye display device also includes a cover plate 340, and the bracket 300 is provided with a second step 350 away from the second sliding portion 320, and the second step 350 is higher than the first step 3101, and the cover plate 340 is covered on the second step 350, for example, it can be bonded, clamped or fastened with a fastener; the end face of the optical module 220 is less than or equal to the end face of the second step 350, and the optical module 220 and the cover plate 340 are spaced apart.

[0067] The end surface of the optical module 220 is smaller than or equal to the end surface of the second step 350 , so that the optical module 220 can correspond to the light-transmitting window 102 , so that the light of the near-eye display module 200 can be emitted through the mounting through hole 310 and the light-transmitting window 102 in sequence.

[0068] The first step 3101 is used to form an inner concave portion 3102 , and the second step 350 prevents the optical module 220 from contacting the cover plate 340 .

[0069] In some embodiments, Figure 6 As shown, the plane A where the two second sliding portions 320 are located is not parallel to the plane B where the mounting through hole 310 is located, and the optical axis of the optical module 220 is not perpendicular to the plane B where the mounting through hole 310 is located.

[0070] That is, the extension line of the plane A where the two second sliding portions 320 are located and the extension line of the plane B where the mounting through hole 310 is located form an angle, and the optical axis of the optical module 220 and the plane B where the mounting through hole 310 are located are not perpendicular.

[0071] Since the optical axis of the optical module 220 is not perpendicular to the plane B where the mounting through hole 310 is located, the optical module 220 will be tilted toward the glasses side. This arrangement allows the light emitted by the microdisplay 210 to pass through the optical module 220 and enter the user's eyes. The user can comfortably watch the image source played by the microdisplay 210 without excessively rotating the eyeballs.

[0072] In some embodiments, Figure 1-Figure 11 As shown, a groove 140 with respect to the cavity 101 is provided on the side of the shell 100 facing away from the bracket 300, and the near-eye display device also includes a cover shell 150 and temples 160, and the cover shell 150 is covered in the groove 140; the near-eye display module 200 also includes an electrical conductor 212 and a circuit board 410, and the circuit board 410 is located outside the fixing seat 230, and the fixing seat 230 is provided with a first through hole 231, and the electrical conductor 212 is passed through the first through hole 231 to electrically connect the micro display 210 and the circuit board 410, and the temples 160 are provided with electrical devices, and the circuit board 410 is electrically connected to the electrical devices.

[0073] The first through hole 231 accommodates the electrical wire 212 , thereby facilitating electrical connection with electrical devices such as a power supply, a control board, etc. located in the temple 160 .

[0074] The near-eye display device further includes a power module and a circuit board 410, wherein the power module is electrically connected to the circuit board 410. The power module may be a button battery, etc., wherein the power module is not shown in the drawings. The power module may be fixed on the circuit board 410.

[0075] The power of the power module is transmitted to the micro display 211 through the circuit board 410 and the electrical wire 212 .

[0076] The micro display 211 is directly opposite to the light-transmitting through hole 2211 on the fixing base 230 .

[0077] The micro display 211 is fixedly connected to the optical module 220. When the optical module 220 moves relative to the bracket 300, the micro display 211 moves synchronously with the optical module 220. The micro display 211 and the optical module 220 can be fixedly connected by means of snap connection, screw connection, etc.

[0078] The power module and the circuit board 410 are fixed on the housing 100, wherein the micro display 211 is electrically connected to the circuit board 410 via the electrical wire 212. When the micro display 211 moves relative to the bracket 300 along with the optical module 220, the electrical wire 212 will deform due to the change in the position of the micro display 211, thereby adapting to the change in the position of the micro display 211.

[0079] For example, the power module and the circuit board 410 may be disposed close to the second position: when the optical module 220 is in the first position, the electrical conductor 212 is in an extended state; when the optical module 220 moves toward the second position, the electrical conductor 212 bends.

[0080] The positional relationship among the micro display 211, the electrical conductor 212 and the circuit board 410 can be set as required. Figure 3 As shown, in this embodiment, the micro display 211, the electrical conductor 212 and the circuit board 410 are arranged in sequence in a straight line.

[0081] In some other embodiments, the micro display 211 , the electrical conductor 212 , and the circuit board 410 are stacked in sequence.

[0082] like Figure 3 As shown, a transparent cover plate 340 is detachably provided on the bracket 300, wherein the optical module 220 is located between the micro display 210 and the cover plate 340. The cover plate 340 can protect the optical module 220.
