[0028] Embodiments

[0029] Reference Figures 1-4 In the present embodiment, a near-eye display device 10 is proposed, comprising:

[0030] The housing assembly 100 is provided with a mounting hole 110. The housing can be made of plastic, metal and the like.

[0031] The optical module 200 is at least partially located in the mounting hole 110. The optical module 200 can receive images produced by the display module 400 and project them into the user's glasses. The optical module 200 can be made of light-transmitting materials such as epoxy resin, glass, etc.

[0032] The flexible member 300 is elastic and is positioned within the mounting hole 110. The material hardness of the flexible member 300 can be less than the hardness of the material of the housing assembly 100 and the material hardness of the optical module 200. The flexible member 300 can be made of rubber, silicone, flexible plastic, or other materials. In other embodiments, it can also be made of easily curable glue.

[0033] In this embodiment, the flexible member 300 is disposed around the optical module 200 and is fixedly connected to the optical module 200. The flexible member 300 is clamped between the inner wall of the mounting hole 110 and the optical module 200, and the flexible member 300 and the inner wall of the mounting hole 110 are tightly fitted. This fit of the flexible member 300 allows the optical module 200 to be fixed in the mounting hole 110 of the housing assembly 100. The optical module 200 and the inner wall of the mounting hole 110 are tightly fitted together, and the flexible member 300 is at least partially deformed in the circumferential direction and the axial direction. It can be understood that the flexible member 300 can have a first thickness in the circumferential direction and the axial direction before being inserted between the inner wall of the mounting hole 110 and the optical module 200. When the optical module 200 and the inner wall of the mounting hole 110 are brought close to each other for clamping, threaded connection or abutment to be tightly fitted, the optical module 200 and the inner wall of the mounting hole 110 are squeezed in the circumferential direction and the axial direction, thereby causing the flexible member 300 to be squeezed and deformed in both the axial direction and the circumferential direction. Of course, if the flexible member 300 is completely placed in the mounting hole 110, the entire circumferential and axial directions of the flexible member 300 are Therefore, when the optical module 200 is installed in the mounting hole 110, the flexible component 300 may have a second thickness in the circumferential direction and the axial direction, and the second thickness is less than the first thickness. The change in thickness brings about a change in deformation, such as the flexible component 300 is squeezed and deformed, etc. This deformation may be irreversible. The flexible component 300 can improve the tight fit of the optical module 200 in the mounting hole 110. In addition, the flexible component 300 realizes protection of the optical module 200, effectively preventing the optical module 200 from being squeezed and damaged, cracked, etc.

[0034] like Figure 5 and Figure 6 As shown, the optical module 200 includes a base 210, a flexible member 300 having a through hole 310, and the base 210 is inserted into the through hole 310. The through hole 310 and the base 210 have the same cross-sectional shape. For example, the cross-sectional shape of the through hole 310 and the base 210 may be circular, rectangular, pentagonal, elliptical, etc.

[0035] The cross-sectional area of ​​the base 210 remains constant along its own axial direction; the cross-sectional area of ​​the through hole 310 remains constant along its own axial direction. After the optical module 200 and the through hole 310 are assembled, the axial directions of the optical module 200 and the through hole 310 are substantially coaxial. Figure 3In FIG. 1 , the direction indicated by arrow a represents the axial direction of the base 210 and the optical module 200 . In the assembled state, the axial directions of the optical module 200 and the through hole 310 are parallel or coaxial.

[0036] The inner wall of mounting hole 110 is provided with a first connecting portion, and the outer wall of base body 210 is provided with a second connecting portion. The first connecting portion and the second connecting portion correspond to and are fixedly connected to each other. The first connecting portion and the second connecting portion are interconnected and at least partially deform the flexible member 300 in the circumferential and axial directions. The cooperation between the first connecting portion and the second connecting portion achieves a fixed connection between optical module 200 and the inner wall of mounting hole 110, and deforms and fixes the flexible member 300 between the optical module 200 and the inner wall of mounting hole 110.

[0037] In this embodiment, see Figure 3 The first connection part is threadedly connected to the second connection part, the first connection part includes an internal thread 311, and the second connection part includes an external thread 211. Due to the threaded connection, the internal thread 311 and the external thread 211 are threadedly connected to each other and deform the flexible part 300 at least partially in the circumferential direction and the axial direction, so the internal and external threads squeeze and deform the flexible part 300. The cross-sectional shape of both the through hole 310 and the base 210 is circular or elliptical. In some embodiments, the internal thread 311 can be processed by hot-melt tapping, and the external thread 211 can be processed by rolling; in some embodiments, the internal and external threads are processed by material removal methods such as turning, milling, and grinding; in some embodiments, the internal and external threads are processed by mold forming or the above-mentioned comprehensive processing methods.

[0038] In other embodiments, the first connecting portion and the second connecting portion are engaged with each other, the first connecting portion including a first engaging structure, and the second connecting portion including a second engaging structure. One of the first engaging structure and the second engaging structure is a protrusion, and the other is a recess. The protrusion and the recess engage with each other and deform the flexible member at least partially in the circumferential and axial directions, i.e., the protrusion and the recess engage and deform the flexible member 300.

[0039] The flexible member 300 is a cylindrical structure, and includes a first end 301 and a second end 302. The first end 301 and the second end 302 are respectively disposed at both ends of the axial direction of the flexible member 300. The first end 301 is closer to the light-emitting side of the optical module 200 than the second end 302. Figure 3 The side direction indicated by arrow a is the light-emitting side direction of the optical module 200 .

[0040] like Figure 6 As shown, in this embodiment, along the axial direction of the flexible member 300 and from the first end 301 to the second end 302 , the wall thickness of the flexible member 300 remains consistent.

[0041] like Figure 7 As shown, in other embodiments, the wall thickness of the flexible member 300 gradually increases along the axial direction of the flexible member 300, and from the first end 301 to the second end 302. Due to the change in the wall thickness of the flexible member 300, when the housing assembly 100, the flexible member 300, and the optical module 200 are assembled, the closer the position is to the second end 302, the tighter the flexible member 300 is clamped by the mounting hole 110 and the optical module 200, thereby effectively improving the fixing effect between the three and preventing loosening.

[0042] In this embodiment, the housing assembly 100 is further provided with a mounting groove 120 , wherein the mounting hole 110 is opposite to the mounting groove 120 , and the mounting hole 110 is communicated with the mounting groove 120 .

[0043] The mounting groove 120 is used to mount the display module 400, which is at least partially located in the mounting groove 120. The optical module 200 is located on the light-emitting side of the display module 400. It can be understood that the light generated by the display module 400 passes through the optical module 200 and enters the user's eyes.

[0044] like Figure 5 As shown, in this embodiment, a flange 220 for limiting is provided at one end of the base 210, and the flange 220 is provided to protrude circumferentially relative to the base 210, for example, to protrude in a whole circle at the end of the base 210. Therefore, when picking up, contacting, and installing the optical module 200, the flange 220 can be directly contacted without contacting the base 210, thereby reducing the probability of damage to the base 210.

[0045] The flange 220 is located outside the through hole 310, and the side of the flange 220 is opaque. Since the side of the flange 220 is opaque, light loss can be reduced and the light extraction efficiency of the optical module 200 can be improved.

[0046] The flange 220 abuts against the end wall of the mounting hole 110. For example, the end surface of the flange 220 facing the mounting hole 110 abuts against the end wall of the mounting hole 110 away from the display module 400, that is, it abuts against the outer surface of the mounting hole 110, thereby ensuring a gap between the base 210 and the display module 400. Thus, during assembly, the flange 220 abuts against the end wall of the mounting hole 110, preventing the base 210 from contacting the display module 400. This prevents the base 210 from touching the display module 400, thereby protecting the microdisplay 410 of the display module 400. Among them, the end face of the flexible part 300 may not exceed the end face of the flange 220, for example, the end face of the flexible part 300 is flush with the end face of the flange 220, or the end face of the flexible part 300 is lower than the end face of the flange 220. Therefore, the base 210 can be conveniently placed into the flexible part 300 from the end of the flange 220, which is conducive to clamping the flange 220 to fix the optical module 200 and the flexible part 300 into the mounting hole 110.

[0047] In this embodiment, an adjusting portion 221 is provided on the outer circumferential surface of the flange 220 . The adjusting portion 221 is configured to drive the optical module 200 to move relative to the housing assembly 100 .

[0048] The flange 220 is located outside the through hole 310. When it is necessary to adjust the position of the display module 400 and the shell assembly 100, or to disassemble the display module 400, the user can directly use tools to act on the flange 220 to adjust or disassemble the display module 400, thereby avoiding wear or damage to the optical module 200.

[0049] The adjustment portion 221 can be a planar structure, a raised structure, or a recessed structure, wherein the number of adjustment portions 221 can be one or more. The number of adjustment portions 221 can include multiple adjustment portions 221 spaced apart along the flange 220. For example, the adjustment portion 221 can be a planar structure, with two adjustment portions 221 arranged in parallel, and the adjustment portion 221 can include at least one pair of mutually parallel planes. Of course, other number of planar structures arranged circumferentially along the flange 220 are also feasible. The user or during production, for example, can use tweezers or a clamp to act on the adjustment portion 221 to adjust the position of the optical module 200.

[0050] like Figure 4 As shown, the housing assembly 100 is provided with a sliding portion 140, which is configured to cooperate with an external mating portion to drive the movement of the housing assembly 100. For example, the mating portion is provided on a wearable article such as a frame of glasses or a helmet. The interaction between the sliding portion 140 and the mating portion allows the housing assembly 100 to move relative to the wearable article, thereby adjusting the position of the housing assembly 100 on the wearable article.

[0051] In this embodiment, the sliding portion 140 protrudes toward the side away from the flexible member 300. There are two sliding portions 140, wherein the flexible member 300 is configured to be installed between the two sliding portions 140. Correspondingly, in order to cooperate with the sliding portion 140, the matching portion includes a sliding groove structure.

[0052] In this embodiment, a back plate 500 is provided on the side of the housing assembly 100 facing away from the optical module 200. The housing assembly 100 is connected to the back plate 500 to cover the mounting groove 120 and seal at least a portion of the display module 400. The display module 400 is at least partially attached to the back plate 500.

[0053] like Figure 3 and Figure 8 As shown, the back plate 500 includes a first surface 510 and a second surface 520 disposed opposite to each other. The first surface 510 is the surface of the back plate 500 close to the display module 400, and the second surface 520 is the surface of the back plate 500 away from the display module 400.

[0054] During assembly, the first surface 510 mates with the microdisplay 410 of the display module 400, thereby dissipating heat from the microdisplay 410. A plurality of heat dissipation structures 521 are disposed on the second surface 520, and the heat dissipation structures 521 may be arranged in an array. In this embodiment, the heat dissipation structures 521 protrude from the second surface 520. In other embodiments, the heat dissipation structures 521 may be recessed into the second surface 520.

[0055] By providing the heat dissipation structure 521 on the second surface 520, the contact area between the backplate 500 and the air can be increased, thereby improving the heat dissipation efficiency of the backplate 500. The array distribution of the heat dissipation structure 521 can ensure more uniform heat dissipation from the backplate 500, thereby preventing local overheating. The backplate 500 can be made of a material with excellent thermal conductivity, such as metal, copper, aluminum, etc.

[0056] In this embodiment, the housing assembly 100 further includes a fastener 101. The housing assembly 100 and the back plate 500 are each provided with a fastening hole 102. The fastener 101 penetrates the fastening hole 102 to secure the back plate 500 to the housing assembly 100. The fastener 101 may include a screw, etc. The fastener 101 cooperates with the fastening hole 102 to achieve a fixed connection between the back plate 500 and the housing assembly 100.

[0057] After the display module 400 is mounted on the housing assembly 100 , the back plate 500 is fixedly connected to the housing assembly 100 , thereby limiting the movement space of the display module 400 and fixing the display module 400 on the housing assembly 100 .

[0058] like Figure 3 、 Figure 8 and Figure 9 As shown, the display module 400 includes a microdisplay 410, an electrical conductor 420 and a circuit board 430. The microdisplay 410 is installed in the mounting groove 120 and is thermally coupled to the back plate 500. The circuit board 430 is located outside the mounting groove 120, and one side of the mounting groove 120 is connected to the mounting notch 130. The microdisplay 410 is passed through the mounting notch 130 through the electrical conductor 420 and is electrically connected to the circuit board 430.

[0059] The microdisplay 410 is located within the mounting slot 120, the electrical wires 420 may be partially exposed relative to the mounting slot 120, and the circuit board 430 may be located outside the mounting slot 120. In other embodiments, the circuit board 430 may be located or partially located within the mounting slot 120, while the electrical wires 420 are at least partially exposed. The electrical wires 420 may be electrically connected to electrical components such as a power supply or a main control board.

[0060] The microdisplay 410 may include Micro-LED (Micro Light-Emitting Diode), uLED (Micro Light Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing) or LBS (Laser Beam Scanning), etc., or any combination of the above products.

[0061] In this embodiment, the micro display 410 is electrically connected to an electrical wire 420. One side of the mounting groove 120 is connected to the mounting notch 130. The mounting notch 130 is used to accommodate the electrical wire 420. The electrical wire 420 can be made of a flexible material.

[0062] The electrical conductors 420 are electrically connected to the circuit board 430, transmitting electrical energy from the circuit board 430 to the microdisplay 410, thereby enabling the normal operation of the microdisplay 410. The circuit board 430 includes a power supply circuit board 430 and a power supply. In some embodiments, the circuit board 420 may be a driver board for driving the microdisplay 410, wherein the electrical conductors 420, the power supply circuit board 430, and the power supply are electrically connected in sequence.

[0063] like Figure 10As shown, in this embodiment, a wearable device 20 is also proposed, including a main body 21 and the near-eye display device 10 mentioned above, and the near-eye display device 10 is arranged on the main body 21. The main body 21 can be, for example, the main shell of a device such as ordinary glasses, smart glasses, and a helmet; for example, the part that fixes the lens; of course, the main body 21 can also be a lens, or it can be a shell part that is directly worn on the user's head. The main body 21 in this embodiment is a frame. In other embodiments, the main body 21 can be a helmet, etc. Other components of the wearable device 20, such as a communication unit, a shell unit, etc., are not described in this application. In some embodiments, the wearable device 20 may also include temples 23 and an upper frame 22. Electrical components such as circuit boards and batteries can be located on the temples 23. The main body 21 includes an environmental side 205 and a human eye side 204. The light-emitting side of the near-eye display device 10 faces the human eye side 204.
