Technical Field
[0001] The present invention relates to a head-mounted display device. Background Art
[0002] With the rapid advancement of current technology, the types and functions of head-mounted display devices are becoming increasingly diverse. For example, if a user has common vision problems such as myopia, hyperopia, or astigmatism, they must prepare a pair of corrective lenses, place them in a lens frame, and then assemble the lens frame to the device so that it is positioned between the device and the user's eyes. Different users of the same augmented reality head-mounted display must also change their corrective lenses and lens frames to suit their needs. Furthermore, assembly issues between the lens frame and the device can affect the effectiveness of vision correction. Summary of the Invention
[0003] The present invention is directed to a head-mounted display device, which can improve the inconvenience of using a user's own vision correction lenses.
[0004] The head-mounted display device of the present invention includes a main body, a first clamping member, a second clamping member, and a sliding member. The main body has a lens seat and two optical lens groups. The lens seat is used to accommodate a first lens and a second lens corresponding to two eyes. The two optical lens groups correspond to two eyes respectively. The first clamping member is arranged on the main body and has a first free end. The first free end is used to contact the first lens. The second clamping member is arranged on the main body and has a second free end. The second free end is used to contact the second lens. The sliding member is slidably arranged on the main body and is located between the first free end and the second free end. When the sliding member slides from an initial position along a first direction, it first pushes the first free end and the second free end to press against the first lens and the second lens respectively, and then pushes the first free end and the second free end to drive the first lens and the second lens to move respectively to change the distance between them and the main body.
[0005] In one embodiment of the present invention, the first clamping member, the second clamping member and the lens holder are integrally formed.
[0006] In one embodiment of the present invention, the first free end portion has a first inclined surface and a third inclined surface. The second free end portion has a second inclined surface and a fourth inclined surface. When the sliding member slides from an initial position in the first direction, it first contacts the first inclined surface and the second inclined surface, and then contacts the third inclined surface and the fourth inclined surface.
[0007] In one embodiment of the present invention, the head-mounted display device further includes a first friction member and a second friction member, which are respectively disposed at the first free end portion and the second free end portion and are used to contact the first lens and the second lens.
[0008] In one embodiment of the present invention, the moving directions of the first lens and the second lens are perpendicular to the first direction.
[0009] Based on the above, in the head mounted display device of the present invention, the lens holder is combined with the body, so there is no assembly and alignment problem between the lens holder and the body, and the lens can be fixed in a proper position by simply operating the sliding member.

[0019] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.
[0020] Figure 1 This is a schematic diagram of a disassembled head-mounted display device according to an embodiment of the present invention. Figure 1The head-mounted display device 100 of this embodiment includes a body 110, a first clamping member 120, a second clamping member 130, and a sliding member 140. The body 110 has a lens holder 112 and two optical lens assemblies 114. The lens holder 112 is used to accommodate a first lens 10 and a second lens 20 corresponding to each eye. The two optical lens assemblies 114 correspond to each eye, respectively.
[0021] In this embodiment, the host 110 can be used in fields such as virtual reality systems, augmented reality systems, or mixed reality systems. The host 110 may include components such as an optical system and a protective housing, and may be provided with a display or be suitable for placing a display. The display may be a built-in display or an external portable display (such as a smartphone), but the present invention is not limited thereto. The optical system includes optical components such as lenses, light guides, or prisms for changing the light path of the display. For example, the host 110 in this embodiment further includes a display (not shown), with two optical lens assemblies 114 positioned between the display and the user's eyes. More specifically, the display can be of various types, corresponding to the virtual reality system, augmented reality system, or mixed reality system, but the present embodiment is not limited thereto. Therefore, light emitted by the display of the host 110 can pass through the optical lens assemblies 114 and enter the user's eyes, or external light can pass through the optical lens assemblies 114 and enter the user's eyes. However, in another embodiment, the host 110 may not have a display, that is, may not have a display function, but may still have two optical lens assemblies 114. Figure 1 The host 110 is shown in a slightly larger form, but the host 110 may also be in the form of thinner glasses or other larger forms. The first lens 10 and the second lens 20 of this embodiment are, for example, located between the optical lens assembly 114 and the user's eyes.
[0022] The first lens 10 and the second lens 20 are not part of the head-mounted display device 100 of this embodiment. That is, when a user obtains the head-mounted display device 100 of this embodiment, the first lens 10 and the second lens 20 are not included. Because the head-mounted display device 100 is designed for all users, it does not have features that can adapt to the vision correction needs of individual users. If a user has vision problems such as myopia, hyperopia, or astigmatism, they can provide their own first lens 10 and second lens 20 with corresponding vision correction functions and install them in the lens holder 112 to achieve a better visual experience. When the head-mounted display device 100 is used by other users, because different users require different vision correction effects, the new user can provide their own first lens 12 and second lens 22 with their own vision correction functions and install them in the lens holder 112 to achieve the same better visual experience.
[0023] The first clamping member 120 is disposed on the main body 110 and has a first free end 122. That is, the first clamping member 120 is fixed at the other end relative to the first free end 122, while the first free end 122 is movable. The first free end 122 is used to contact the first lens 10. Similar to the first clamping member 120, the second clamping member 130 is disposed on the main body 110 and has a second free end 132. The second free end 132 is used to contact the second lens 20. The sliding member 140 is slidably disposed on the main body 110. That is, the sliding member 140 can slide on the main body 110 but is restricted from leaving the main body 110. The sliding member 140 is located between the first free end 122 and the second free end 132.
[0024] Figure 2A yes Figure 1 Schematic diagram of the lens seat portion of the head-mounted display device. Figure 2B yes Figure 2A A partial enlarged schematic diagram. Figure 2C yes Figure 2A A magnified view of the area after removing the slider and changing the viewing angle. Figure 2D yes Figure 2A Please refer to the schematic diagram of the sliding parts. Figures 2A to 2D The user first intuitively places the first lens 10 and the second lens 20 in the lens holder 112. At this point, the first lens 10 and the second lens 20 are naturally in contact with the optical lens assembly 114 in the body 110 due to the influence of gravity. Therefore, the minimum distance G10 between the first lens 10 and the second lens 20 and the optical lens assembly 114 in the body 110 is zero.
[0025] In this embodiment, the first free end portion 122 has a first inclined surface 122A and a third inclined surface 122C. The second free end portion 132 has a second inclined surface 132B and a fourth inclined surface 132D. Figure 2A When the slider 140 slides along a first direction D10 from an initial position P10, it first contacts the first inclined surface 122A of the first free end portion 122 and the second inclined surface 132B of the second free end portion 132. The force applied by the slider 140 to the first inclined surface 122A causes the first free end portion 122 to move toward the first lens 10. The force applied by the slider 140 to the second inclined surface 132B causes the second free end portion 132 to move toward the second lens 20.
[0026] Figure 3A yes Figure 2A Schematic diagram of the middle sliding member after sliding a distance. Figure 3B yes Figure 3A Please refer to the enlarged diagram of the part. Figure 3A and Figure 3B , when the sliding member 140 moves from Figure 2A After the initial position P10 of the sliding member 140 slides along the first direction D10 for a distance, the first free end portion 122 and the second free end portion 132 are pushed to the position of respectively pressing against the first lens 10 and the second lens 20. At this time, the sliding member 140 has not yet contacted the third inclined surface 122C and the fourth inclined surface 132D (marked at Figure 2C ), and the first lens 10 and the second lens 20 have not moved yet, so the minimum distance G10 between them and the optical lens assembly 114 in the body 110 remains zero.
[0027] Figure 4A yes Figure 3A Schematic diagram after the middle sliding member slides a distance further. Figure 4B yes Figure 4A Please refer to the enlarged diagram of the part. Figure 4A and Figure 4B , when the sliding member 140 moves from Figure 3AAfter sliding a further distance along the first direction D10, the slider 140 contacts the third inclined surface 122C and the fourth inclined surface 132D. The force applied by the slider 140 on the third inclined surface 122C pushes the first free end 122, causing the first free end 122 to move the first lens 10 away from the optical lens assembly 114. The force applied by the slider 140 on the fourth inclined surface 132D pushes the second free end 132, causing the second free end 132 to move the second lens 20 away from the optical lens assembly 114. As a result, the distance G10 between the first lens 10 and the second lens 20 and the optical lens assembly 114 within the body 110 increases from zero. In other words, a gap is maintained between the first lens 10 and the second lens 20 and the optical lens assembly 114. This prevents wear caused by contact between the first lens 10 and the optical lens assembly 114, and between the second lens 20 and the optical lens assembly 114, and also prevents light leakage and energy loss caused by contact between the two.
[0028] Thanks to the coordination between the first and second clamping members 120, 130, and the sliding member 140, even when replacing first and second lenses 10, 20 of different thicknesses, the gaps between the first lens 10 and the optical lens assembly 114, as well as the gaps between the second lens 20 and the optical lens assembly 114, can be adjusted to the desired size without contact. This prevents friction and damage caused by contact between the first lens 10 and the optical lens assembly 114, and between the second lens 20 and the optical lens assembly 114, and also prevents light leakage and energy loss caused by contact. On the other hand, if the gaps are too large and not restricted, considering the possibility of using thicker corrective lenses, the distance between the optical lens assembly 114 and the eyes will be further increased, resulting in a narrowed field of view and making it easier for the eyes to see the edges of the optical lens assembly 114, reducing the user experience.
[0029] Please refer to Figure 1 In this embodiment, the first clamping member 120, the second clamping member 130, and the lens holder 112 may be integrally formed, but the present invention is not limited thereto. Furthermore, the head-mounted display device 100 of this embodiment may further include a first friction member 150 and a second friction member 160, respectively disposed at the first free end 122 and the second free end 132, and configured to contact the first lens 10 and the second lens 20. The first friction member 150 and the second friction member 160 may be made of, for example, rubber or other suitable materials to effectively drive the movement of the first lens 10 and the second lens 20.
[0030] Please refer to Figure 2A and Figure 2DIn this embodiment, the portion of the sliding member 140 that contacts the first bevel 122A is the bevel 140A, the portion that contacts the third bevel 122C is the bevel 140C, the portion that contacts the second bevel 132B is the bevel 140B, and the portion that contacts the fourth bevel 132D is the bevel 140D, but the present invention is not limited thereto. On the other hand, the sliding member 140 that contacts the first free end 122 and the second free end 132 may also be bevels, and the appearance of the portions corresponding to the first free end 122 and the second free end 132 is not limited. Alternatively, the appearance of the three may be other appropriate matching types, as long as the sliding member 140 can smoothly push the first free end 122 and the second free end 132 toward the first lens 10 and the second lens 20 respectively, and then push the first free end 122 and the second free end 132 to drive the first lens 10 and the second lens 20 to move away from the main body 110. Please refer to Figure 4A For example, the moving direction D20 of the first lens 10 and the second lens 20 is perpendicular to the first direction D10 , but the present invention is not limited thereto.
[0031] In summary, in the head-mounted display device of the present invention, the main body and lens holder are inherently integrated, eliminating the need for users to assemble the lens holder to the main body or perform alignment. Furthermore, after inserting the corrective lens into the lens holder, the user simply operates a slider to maintain zero contact between the lens surface and the device, enhancing product reliability. Not only can users use their own corrective lenses with the head-mounted display device, but the lenses can also be easily assembled directly into the head-mounted display device and aligned with the optical lens assembly within the device, making this a simple and lightweight solution.
