[0038] In the present invention, the word "exemplary" is used to mean "used as an example, illustration or description". Any embodiment described as "exemplary" in the present invention is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention 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 invention.

[0039] The embodiments of the present invention provide a near-eye display device, which is described in detail below.

[0040] See also Figure 1-12 The present invention provides a near-eye display device 1, 1', which is applied to an optical lens 2. The lens 2 can be goggles, smart glasses, myopia glasses, hyperopia glasses, sports glasses or other near-eye or head-mounted optical lenses, etc. The user's lens 2 can face the user's glasses, which includes:

[0041] The mounting base 10 is configured to install the optical machine 20. The mounting base 10 may be provided with a mounting groove. The mounting base 10 may be made of plastic or metal or other materials. The optical machine 20 is located in the mounting groove, wherein the optical machine 20 may include a micro display, such as 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 these technologies. It can be understood that the optical machine 20 may also include a micro-optical module, etc. The micro-optical module is arranged in front of the micro display, and the light of the display is emitted after passing through the micro-optical module.

[0042] The first connection part 30 is arranged on the mounting seat 10, and is configured to be connected to the first side of the lens 2; and the second connection part 40 is arranged opposite to the first connection part 30, and is configured to be connected to the second side of the lens 2, and the first side and the second side of the lens 2 are two sides arranged oppositely; the first side and the second side of the lens 2 are two sides arranged oppositely, and it can be understood that the first side can be the side of the lens 2 facing the human eye, and the second side can be the side of the lens 2 away from the human eye. Among them, the first connection part 30 and the second connection part 40 are configured to clamp the lens 2 with each other and allow the mounting seat 10 to move on the lens 2 to adjust the position of the optical machine 20 relative to the lens 2. It can be understood that, for example, when the lens 2 has at least one first position and a second position different from the first position, it can be freely moved between the first position and the second position; wherein, the specific movement can also be a movement of a position at a certain distance relative to the periphery of the lens, or it can be a movement of any position relative to the lens 2. As long as it can meet the requirement of adjusting the light output position of the optical machine 20 relative to the visual range of the human eye, it can be adjusted.

[0043] By adjusting the position of the optical machine 20 relative to the human eye field of view, the position of the optical machine can be accurately adjusted to achieve its light to the human eye vision, thereby meeting the needs of different people with different pupil distances or field of view ranges, and meeting the viewing needs and preferences of different users. On the other hand, it can also provide flexible position testing in the early stage of research and development to achieve the expected design effect.

[0044] Among them, the first connection part 30 and the second connection part 40 can be understood as mutually connected parts, such as mutually connected plates. For example, the first connection part 30 can be a part of the mounting seat 10, or an independent component, which is fixed to the mounting seat 10 by bonding, clamping or threaded connection, etc. The second connection part 40 can be a relatively independent component, for example, it can be a component that cooperates with the first connection part 30 to clamp or adsorb. For example, the first connection part 30 and the second connection part 40 can be clamped by clamping plates, or clamped by magnetic attraction, or a combination of the above solutions, etc.

[0045] In some embodiments, in conjunction with Figure 2-6 The display device 1 may further include a first protective layer 51 and a second protective layer 52, the first protective layer 51 is connected to the first connecting portion 30 and faces the second connecting portion 40, the second protective layer 52 is connected to the second connecting portion 40 and faces the first connecting portion 30, the first protective layer 51 and the second protective layer 52 are configured to contact the lens 2 and not damage the lens 2 when the first connecting portion 30 and the second connecting portion 40 move relative to the lens 2. In practical applications, since the lens 2 is mostly a precision device, such as made of resin or glass, etc., moving the optical machine 20 through the first connecting part 30 and the second connecting part 40 too many times can easily cause the lens 2 to be worn. Therefore, the protective layer can be provided to play a buffering and protective role to prevent the rigid materials of the first connecting part 30 and the second connecting part 40 from directly wearing the lens 2. The first protective layer 51 and the second protective layer 52 can be made of relatively soft materials, such as PVC (polyvinyl chloride), sponge, rubber, plastic, etc. The first protective layer 51 and the second protective layer 52 can also be a thinner layer of material, such as a coating or a coating can be provided at the connection part corresponding to the contact surface of the lens 2, as long as it can contact the lens 2 and is not easy to cause damage to the lens 2 during the movement to achieve a certain degree of protection. Of course, protective layers can also be provided on both sides of the first connecting part 30 or the second connecting part 40 to ensure the integrity of the whole.

[0046] In some embodiments, the first connection part 30 and the second connection part 40 may be magnetic materials that attract each other, the first connection part 30 and the second connection part 40 may be magnets, or the first connection part 30 may be a metal such as iron, cobalt, nickel, and alloys thereof, and the second connection part 40 may be a magnet. Of course, the order of the first connection part 30 and the second connection part 40 may also be reversed, as long as a clamping effect similar to that of a clamp can be achieved.

[0047] In some embodiments, in conjunction with Figure 3 or Fig.10 The first connection portion 30 is integrally formed with the mounting seat 10, that is, the first connection portion 30 is the bottom of the mounting seat 10 (such as Figure 3 ) or top (such as Fig.10), that is, a portion corresponding to the side facing the second connecting part 40 can be clamped with the second connecting part 40. For example, the mounting seat 10 can be made of metal and the second connecting part 40 is a magnet.

[0048] In some embodiments, in conjunction with Figure 1 , 7 8, the display device 1 may also include a connector 50, one end of the connector 50 is connected to the first connecting part 30 and / or the first protective layer 51, and the other end is connected to the second connecting part 40 and / or the second protective layer 52. The connector 50 is configured to span the lens 2, for example, the connector 50 may be U-shaped. It is understood that the two ends of the connector 50 may be directly connected (for example, bonding, etc.) to the first connecting part 30 and the second connecting part 40; since the protective layer is directly connected to the connecting part, the connector 50 may also be connected to the first protective layer or the second protective layer 52, and optionally, the connector 50 may also wrap the first connecting part 30 or the second connecting part 40. The provision of the connector 50 can reduce the probability of component loss. It is understood that the display module of the present invention is relatively small relative to the human eye, and the maximum diameter of a single first or second connecting part is 5 mm or less; therefore, connecting the first connecting part 30 and the second connecting part 40 together can ensure that it is connected to the lens 2 or the frame as a whole, and when it falls, the whole formed by it is also relatively large, which is easier to find or pick up. Optionally, refer to Figure 7 The connecting member 50 can also be designed as an integral whole with the protective layer, using the same material. For example, the first protective layer 51, the second protective layer 52 and the connecting member 50 are made into a whole. In this case, the connecting member 50 can play the role of connection and protection at the same time.

[0049] Optionally, the first connecting part 30 and the second connecting part 40 are made of non-magnetic materials, and the connecting part 50 can also play a role in adjusting the moving distance range. The movement of the first connecting part 30 and the second connecting part 40 on the lens 2 can be within a range of approximately half the length of the connecting part 50, for example, a lateral range of approximately half the length of the connecting part 50 from the lens 1 frame 3, etc.

[0050] In other embodiments, the connecting member 50 may be a torsion spring, memory metal, plastic, rope, etc. For example, the first connecting portion 30 and the second connecting portion 40 are clamped plates, and the connecting member 50 is a torsion spring. If the first connecting portion 30 and the second connecting portion 40 are magnetic materials that are attracted to each other, the connecting member may be omitted. In order to reduce the loss of magnets due to small size, any feasible connecting member 50 may be used. In other embodiments, the connecting member 50 may be replaced, for example, to adapt to the position movement of different lenses 2. Optionally, the connecting member 50 may also be telescopic or elastic, that is, its overall length is adjustable.

[0051] Optionally, the first connection part 30 can be separated from the mounting base 10. Referring to FIG. 4-7, a groove 113 is provided on the side of the mounting base 10 facing away from the optical engine 20. The first connection part 30 is arranged in the groove 113, and then the first protective layer 51 is arranged on the first connection part 30. For example, bonding can be adopted. The first connection part 30 can be an iron sheet or a magnet, etc. Fig.11 The mounting base 10 is provided with a groove 113 on one side facing the optical engine 20. The first connecting portion 30 may be a magnet or an iron block located in the groove 113, for example, one is provided on each side of the mounting base 10. Fig.12 As mentioned above, the number of the first connection parts 30 may be greater, for example, four first connection parts 30 may be provided in the circumferential direction.

[0052] In some embodiments, the maximum diameter of the first connecting portion 30 and / or the second connecting portion 40 is less than or equal to 5 mm. The small size of the connecting portion can achieve lightweight adaptation and is not likely to cause excessive impact on the applied optical lens.

[0053] See also Figure 1-12 The display device 1, 1' may further include a sleeve 60. The optical machine 20 is arranged in the sleeve 60 to encapsulate and protect the optical machine 20. The mounting seat 10 is provided with a mounting groove 13. The sleeve 60 is arranged in the mounting groove 13 to configure the light output angle of the optical machine 20. The shape of the sleeve 60 can be adapted to the shape of the optical machine 20. For example, it can be a cylindrical sleeve, so that the optical machine 60 can be fixed to emit light at a specific angle; optionally, the sleeve 60 can also be other shapes, such as a spherical shape, etc. The display device may further include an arc-shaped spring piece (not shown in the figure). The arc-shaped spring piece is arranged in the mounting groove 13 and abuts against the sleeve 60. The arc-shaped spring piece can make the assembly of the spherical mounting groove 13 and the spherical sleeve 60 more tightly matched, thereby reducing the probability of the sleeve 60 shaking at will. The sleeve 60 is provided with a first through hole 61 and an assembly groove, the first through hole 61 is connected to the assembly groove (not shown), the optical engine 2 is arranged in the assembly groove, and the end surface of the optical engine 2 is lower than the end surface of the assembly groove to reduce the risk of friction damage to the optical engine 2; the mounting seat 10 is provided with an outlet hole 111 connected to the mounting groove 13, the first through hole 61 and the outlet hole 111 are connected to configure the electrical wiring of the optical engine 20. It can be understood that the optical engine 20 can also be provided with an electrical component (such as a circuit board or a lead, etc.), which can be connected to an external power supply or a driving board to drive the optical engine 20, and the lead of the optical engine 20 can be led to the outlet hole 111 through the first through hole 61 and then connected to an external power supply or a wire, etc.

[0054] In some embodiments, see Figure 1-7The mounting seat 10 may include a base 11 and a spherical seat 12 arranged on the base 11. The base 11 may be cylindrical, truncated cone or prism-shaped. The base 11 is provided with a wire outlet hole 111. The spherical seat 12 is provided with a mounting groove 13. The mounting groove 13 is a spherical mounting groove. The spherical seat 12 may be formed by a plurality of arc-shaped walls spaced around the base 11, and it may have a certain deformation amount under external force. The sleeve 60 is a spherical sleeve. The spherical sleeve 60 is configured to allow rotation in the spherical mounting groove to adjust the light output angle of the optical machine 20. When the light output angle of the optical machine 20 needs to be adjusted, the rotation direction of the spherical sleeve 60 can be operated, such as adjusting with fingers or special tools. In one embodiment, the display device further includes an arc-shaped spring sheet (not shown), which is arranged in the mounting groove 13 and abuts against the sleeve 60. The arc-shaped spring sheet can make the assembly of the spherical mounting groove 13 and the spherical sleeve 60 more tightly matched, reducing the probability of the sleeve 60 shaking at will. The spherical sleeve 60 is placed in the spherical mounting groove and limited by the spherical seat 12. The first connecting portion 30 and the second connecting portion 40 are away from the light emitting side of the optical engine 20. This type of design can ensure that the optical engine 20 is directly facing the side of the human eye, such as Figure 1 As shown, the entire mounting base 10 can be located on the side of the lens 2 facing the human eye, that is, the light of the optical machine 20 can enter the human eye without passing through the lens 2, that is, the built-in assembly method of the optical machine 20 can allow the light of the optical machine 20 to directly enter the human eye without considering the light influence brought by the lens 2, such as the loss of the light of the optical machine and so on.

[0055] In some other embodiments, Figure 4-7 , the first connection part 30, the second connection part 40 and the sleeve 60 are coaxially arranged, the outlet hole 111 is exposed relative to the side wall of the base 11, and the axial direction of the outlet hole 111 is perpendicular to the connection direction of the first connection part 30 to the second connection part 40, and the wiring groove of the outlet hole 111 is shielded by the first connection part 30 and hidden inside the base 11. Among them, the first through hole 61 can be located at the center bottom of the sleeve 60, and can also be coaxially arranged with the base 11. The above-mentioned hidden wiring can make the overall appearance more beautiful, and the coaxial arrangement can not affect the angle adjustment of the ball head sleeve 60.

[0056] In some embodiments, in conjunction with Figure 8-10The mounting seat 10 may include a first assembly seat 13 and a second assembly seat 14 arranged on the first assembly seat 13. The first assembly seat 13 and the second assembly seat 14 may be arranged in parallel. For example, the first assembly seat 13 and the second assembly seat 14 may be fixed by bonding or magnetic attraction. In some embodiments, the first assembly seat 13 and the second assembly seat 14 adopt a magnetic attraction method to facilitate the disassembly and assembly of the assembly seat, which is beneficial to the installation and replacement of the optical machine 20. At the same time, the magnetism of the first assembly seat 13 and the second assembly seat 14 can be fully utilized to further combine with the magnetic attraction method of the first connecting part 30 and the second connecting part 40, so that the assembly of the entire device is more flexible.

[0057] Continue reading Figure 8-10 It can be understood that a positioning hole 114 and a positioning column 115 can be provided between the first assembly seat 13 and the second assembly seat 14. The positioning column and the positioning hole can play a foolproof positioning role. Of course, in some implementations, the positioning column 115 can also be a part of the first connection part 30. The first assembly seat 13 is provided with a wire outlet hole 111, and the first assembly seat 13 and the second assembly seat 14 are coaxially provided with a mounting groove 13. The mounting groove 13 is a spherical mounting groove, and the sleeve 60 is a spherical sleeve. The spherical sleeve 60 is configured to allow rotation in the spherical mounting groove to adjust the light output direction of the optical machine 20. When the light output angle of the optical machine 20 needs to be adjusted, the rotation direction of the spherical sleeve 60 can be operated, such as adjusting with fingers or special tools, wherein the first connection part 30 and the second connection part 40 face the light output side of the optical machine 20. The wire outlet hole 111 can be located on the side of the first assembly seat 111 away from the optical machine 20.

[0058] In some embodiments, continue to refer to Figure 8-10 , the first protective layer 51, the second protective layer 52 and the second connecting part 40 are provided with a light exit hole 53. The size of the light exit hole 52 can be larger than the size of the optical machine 20. The light exit hole 53 ensures that the light of the optical machine 20 can reach the human eye. It can be understood that the entire mounting seat 10 can be located on the side of the lens 2 away from the human eye, and the first connecting part 30 and the second connecting part 40 can be spaced relative to the two sides of the light exit hole 53, that is, the light of the optical machine 20 first passes through the lens 2 and then enters the human eye, that is, the external assembly method of the optical machine 20. This method (relative to the internal assembly method of the optical machine 20) can reduce the discomfort caused by the mounting seat 10 as a whole protruding relative to the lens 2 and directly facing the human eye, such as psychological discomfort, etc.

[0059] In some embodiments, see Figure 10-12The first assembly seat 13 and the second assembly seat 14 can be square or elliptical in shape. The side wall height of the spherical mounting groove 13 formed by the first assembly seat 13 and the second assembly seat 14 is greater than the radius of the spherical sleeve 60. The spherical shape here can be understood as the spherical side wall portion of the spherical mounting groove 13 and the spherical sleeve directly contacting each other. The other parts of the spherical sleeve 60 (for example, the part that does not contact the side wall of the mounting groove 13) can be other non-spherical shapes, for example, the position close to the end face can be trumpet-shaped or cylindrical, etc. Of course, in order to facilitate manufacturing, the spherical sleeve 60 can also be an overall standard sphere. Ensure that the height at which the inner wall of the mounting groove 13 contacts the spherical sleeve 60 is at least greater than the center height of the spherical sleeve, and ensure that the first assembly seat 13 and the second assembly seat 14 restrict the spherical sleeve 60 from falling by pressing up and down. In one embodiment, the display device also includes an arc-shaped spring piece (not shown in the figure), which is arranged in the mounting groove 13 and abuts against the sleeve 60. The arc-shaped spring piece can make the assembly of the spherical mounting groove 13 and the spherical sleeve 60 more tightly fitted, thereby reducing the probability of the sleeve 60 shaking at will.

[0060] In some embodiments, see Figure 1 , 12 The near-eye display device may further include a frame 3, a lens 2 is disposed on the frame 3, and a connector 50 spans the frame 3 and is located on opposite sides of the lens 2. The connectors 50 located on both sides of the lens 2 may be substantially symmetrically designed to ensure that the first connecting portion 30 and the second connecting portion 40 are centrally aligned.

[0061] A near-eye display device provided by an embodiment of the present invention is introduced in detail above.
