Abstract
Description
Technical Field
[0001] This invention relates to the technical field of eyeglasses, and more specifically to eyeglasses with adjustable interpupillary distance. Background Technology
[0002] Currently, the concept of the metaverse is gaining increasing popularity, and related industries are developing rapidly. The metaverse provides immersive experiences based on extended reality (XR) technology, generates a mirror image of the real world based on digital twin technology, and builds an economic system based on blockchain technology. It closely integrates the virtual and real worlds in terms of economic, social, and identity systems, and allows each user to produce content and edit their world. Extended reality technology, including VR, AR, and MR technologies, is the foundation of the metaverse.
[0003] VR technology is typically based on head-mounted display devices, i.e., VR glasses. Existing VR glasses have lenses fixedly attached to the frame, and the designed interpupillary distance (IPD) is usually a fixed distance. To accommodate users with different IPDs, the lens area of VR glasses is often designed to be large. However, when the lens area of VR glasses becomes larger, the refractive index leads to poor optical imaging, affecting the user's visual experience. Furthermore, when the user's IPD deviates significantly from the designed IPD of the VR glasses, the user's visual experience while wearing VR glasses is greatly reduced.
[0004] To address the aforementioned issues, conventional technical solutions employ lens interpupillary distance adjustment devices composed of complex structural components such as transmission rods, gears, and push blocks. These solutions require significant space and cannot achieve lightweight design. Therefore, designing eyeglasses with a simple, reliable, and relatively lightweight interpupillary distance adjustment device has become an urgent problem to be solved. Summary of the Invention
[0005] This application embodiment provides a pair of eyeglasses, the eyeglasses comprising:
[0006] Eyeglass frame, including a first frame and a second frame arranged adjacent to each other;
[0007] The first lens is embedded in the first frame;
[0008] The second lens is embedded in the second frame;
[0009] An interpupillary distance adjustment device includes a controllable elastic body, the controllable elastic body including a first controllable elastic body and a second controllable elastic body, the first controllable elastic body being disposed on the inner sidewall of the first frame and supporting the edge of the first lens, and the second controllable elastic body being disposed on the inner sidewall of the second frame and supporting the edge of the second lens.
[0010] The deformation of the first controllable elastomer and / or the second controllable elastomer can be controlled to adjust the interpupillary distance between the first lens and the second lens.
[0011] The eyeglasses provided in this application embodiment have a controllable elastomer structure designed between the inner sidewall of the frame and the edge of the lens. By controlling the deformation of the controllable elastomer, the interpupillary distance between the lenses can be adjusted. The eyeglasses are simple, reliable and lightweight, which can greatly improve the user's eyeglasses experience. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0030] Please see Figure 1 , Figure 1This is a schematic diagram of the overall structure of an embodiment of the glasses in this application. It should be noted that the glasses in this application may include VR (Virtual Reality) or AR (Augmented Reality) glasses. This embodiment only illustrates a simple illustrated structure of glasses. As shown in the figure, the glasses 100 in this embodiment includes a frame 110, lenses 120 (represented by dashed lines in the figure), and an interpupillary distance adjustment device 130.
[0031] Specifically, the frame 110 includes a first frame 111 and a second frame 112 arranged adjacent to each other, and the lens 120 includes a first lens 121 and a second lens 122, wherein the first lens 121 and the second lens 122 are respectively embedded in the first frame 111 and the second frame 112.
[0032] In this embodiment, the interpupillary distance adjustment device 130 includes a controllable elastic body 131, which includes a first controllable elastic body 1311 and a second controllable elastic body 1312. The first controllable elastic body 1311 is disposed on the inner sidewall of the first frame 111 and supports the edge of the first lens 121, while the second controllable elastic body 1312 is disposed on the inner sidewall of the second frame 112 and supports the edge of the second lens 122. By controlling the deformation of either the first controllable elastic body 1311 or the second controllable elastic body 1312, the interpupillary distance L between the first lens 121 and the second lens 122 can be adjusted.
[0033] Optionally, the first controllable elastomer 1311 and the second controllable elastomer 1312 can be bonded to the inner sidewall of the first frame 111 and the inner sidewall of the second frame 112, respectively, or fixedly connected in other ways. The side of the first controllable elastomer 1311 facing away from the first frame 111 can be bonded to the edge of the first lens 121, and can drive the first lens 121 to move relative to the first frame 111 within a predetermined range (generally the assembly connection area of the first lens 121 and the first frame 111). The side of the second controllable elastomer 1312 facing away from the second frame 112 can be bonded to the edge of the second lens 122, and can drive the second lens 122 to move relative to the second frame 112 within a predetermined range (generally the assembly connection area of the second lens 122 and the second frame 112).
[0034] Optionally, the controllable elastomer 131 can be an elastic capsule or other structure that can undergo controllable elastic deformation under certain stimuli or effects. The specific structural form and principle of the controllable elastomer 131 as an elastic capsule will be described in detail in subsequent embodiments.
[0035] The eyeglasses provided in this application embodiment can adjust the interpupillary distance between lenses by designing a controllable elastomer structure between the inner sidewall of the frame and the edge of the lens, thereby controlling the deformation of the controllable elastomer. It has the characteristics of simple, reliable and lightweight structure, which can greatly improve the user's eyeglasses experience.
[0036] Please see Figure 2 , Figure 2 This is a schematic diagram of the overall structure of another embodiment of the eyeglasses of this application; the eyeglasses 100 in this embodiment also include a frame 110, lenses 120 and an interpupillary distance adjustment device 130.
[0037] Specifically, the frame 110 includes a first frame 111 and a second frame 112 arranged adjacent to each other, and the lens 120 includes a first lens 121 and a second lens 122, wherein the first lens 121 and the second lens 122 are respectively embedded in the first frame 111 and the second frame 112.
[0038] Optionally, the interpupillary distance adjustment device 130 in this embodiment includes a controllable elastic body 131, which includes a first controllable elastic body 1311 and a second controllable elastic body 1312. The first controllable elastic body 1311 is disposed on the inner sidewall of the first frame 111 and supports the edge of the first lens 121, while the second controllable elastic body 1312 is disposed on the inner sidewall of the second frame 112 and supports the edge of the second lens 122. By controlling the deformation of either the first controllable elastic body 1311 or the second controllable elastic body 1312, the interpupillary distance L between the first lens 121 and the second lens 122 can be adjusted.
[0039] In this embodiment, both the first controllable elastomer 1311 and the second controllable elastomer 1312 are elastic capsule structures. A medium can be filled into or discharged within the elastic capsule structure, thereby changing its volume. The elastic capsule structure can be made of elastic materials such as rubber. The elastic capsule structure can be filled into or discharged with media materials including gases and liquids, such as air and water.
[0040] Optionally, the interpupillary distance adjustment device 130 in this embodiment further includes a pump body 132, which is connected to the controllable elastomer 131 through a pipeline 133 and is used to fill the controllable elastomer 131 (the first controllable elastomer 1311 and the second controllable elastomer 1312) with a medium.
[0041] The pump body 132 can be an air pump or a liquid pump, etc. If it is a liquid pump structure, a liquid storage tank or similar structure can also be included. In this embodiment, the pump body 132 is described using an air pump structure as an example. Please refer to... Figure 3 , Figure 3This is a schematic diagram of a pump body according to an embodiment of the present application. The pump body 132 includes an air inlet 1321 and an air outlet 1322. The air inlet 1321 is used to draw in air, and the air outlet 1322 is connected to a pipe 133 (see also...). Figure 2 It is connected to the controllable elastomer 131 and is used to fill the controllable elastomer 131 with air. When the pump body 132 stops filling the controllable elastomer 131 with medium, the controllable elastomer 131 can squeeze the medium out according to its own elasticity (such as elastic capsule structure) characteristics, and then restore its shape or state.
[0042] Optionally, please refer to the following as well. Figures 4 to 6 , Figure 4 This is a schematic diagram of the structure of the eyeglasses of this application, showing the fit between the frame and the lens. The dotted lines in the diagram represent the lens. Figure 5 This is a cross-sectional view of one side of the first frame structure. Figure 6 This is a cross-sectional view of one side of the structure of the second frame. In this embodiment, there can be multiple first controllable elastic bodies 1311, evenly arranged along the inner wall of the first frame 111; there can also be multiple second controllable elastic bodies 1312, evenly arranged along the inner wall of the second frame 112. In this embodiment, four first controllable elastic bodies 1311 and four second controllable elastic bodies 1312 are used. The four first controllable elastic bodies 1311 are arranged in pairs facing each other along the inner wall of the first frame 111, and the four second controllable elastic bodies 1312 are arranged in pairs facing each other along the inner wall of the second frame 112.
[0043] In another embodiment, the number of first controllable elastomers 1311 and second controllable elastomers 1312 can both be multiple. The multiple first controllable elastomers 1311 are linearly symmetrical with respect to the horizontal direction, and the multiple second controllable elastomers 1312 are also linearly symmetrical with respect to the horizontal direction. This facilitates stable and reliable adjustment of the optical center of each lens along the horizontal direction to increase or decrease the interpupillary distance of the glasses, ensuring that the line connecting the optical centers of two lenses remains horizontal. In yet another embodiment, the number of first controllable elastomers 1311 and second controllable elastomers 1312 can both be multiple. The multiple first controllable elastomers 1311 are linearly symmetrical with respect to the vertical direction, and the multiple second controllable elastomers 1312 are also linearly symmetrical with respect to the vertical direction. This facilitates stable and reliable adjustment of the optical center of each lens along the vertical direction while maintaining a constant interpupillary distance of the glasses.
[0044] Optionally, the eyeglasses structure in this embodiment may consist of four independently controllable elastic bodies 131 respectively attached to the inner circumference of the frame 110 (first frame 111 and second frame 112). In this embodiment, an elastic airbag structure is used as an example. Each independent airbag occupies almost 1 / 4 of the inner circumference of the frame, and the four elastic airbags can firmly fix the lens 120 in the frame 110. The pump body 132 can be a miniature piezoelectric pump, whose main function is to inflate the elastic airbags, causing them to expand and thus fix the lens 120 (first lens 121 and second lens 122).
[0045] It is readily understood that the number of elastic air bladders is not limited to four; it can also be five or more. Multiple elastic air bladders can be arranged linearly symmetrically along the horizontal or vertical direction, and can be linearly symmetrical with respect to the horizontal direction. This facilitates stable and reliable adjustment of the optical center of each lens along the horizontal direction to increase or decrease the pupillary distance of the glasses, ensuring that the line connecting the optical centers of two lenses remains horizontal. In another embodiment, the multiple elastic air bladders can be linearly symmetrical with respect to the vertical direction. This facilitates stable and reliable adjustment of the optical center of each lens along the vertical direction while maintaining a constant pupillary distance.
[0046] Please continue reading. Figure 5 and Figure 6 The interpupillary distance adjustment device 130 in this embodiment also includes a valve 134, which can be connected to the medium inlet / outlet of the controllable elastomer 131 or disposed on a pipeline. In one embodiment, a valve 134 can be disposed corresponding to each controllable elastomer. Optionally, the valve 134 can be a miniature solenoid valve and can be integrated at the medium inlet / outlet position of the controllable elastomer. Please refer to [link / reference] for details. Figure 5 and Figure 6 Each first controllable elastic body 1311 and each second controllable elastic body 1312 corresponds to a valve 134, and the valve 134 may be a medium inlet or outlet located on the inner side of each first controllable elastic body 1311 and each second controllable elastic body 1312.
[0047] The main functions of the pipeline 133 connecting the pump body 132 (micro air pump) and the elastic airbag (controllable elastomer 131) and the valve 134 integrated thereon are as follows: when the micro solenoid valve (valve 134) is opened, the pipeline 133 serves as the channel for the micro air pump to be inflated and the channel for the elastic airbag to be deflated; when the micro solenoid valve is closed, it can seal the gas in the elastic airbag, thereby enabling the elastic airbag to fix the lens 120.
[0048] The working principle of the interpupillary distance adjustment device 130 is as follows: Figures 7a-7e As shown. Among them, Figure 7aThis represents the initial state of the interpupillary distance adjustment device (lenses are represented by dashed lines); Figure 7b This represents the first state in which the interpupillary distance adjustment device adjusts the lens; Figure 7c This represents the second state in which the interpupillary distance adjustment device adjusts the lens; Figure 7d This represents the third state in which the interpupillary distance adjustment device adjusts the lens; Figure 7e This represents the fourth state where the interpupillary distance adjustment device adjusts the lens. It should be noted that, in order to make the lens offset more obvious, the lens illustrations in Figures 7b-7e are intentionally set to black. The color and transparency of the lens are not specified here; this is just for illustrative purposes.
[0049] In the initial state ( Figure 7a In the neutral state, the four elastic air bladders (using the first controllable elastomer 1311 as an example in the diagram) are empty or contain an equal amount or pressure of gas. At this time, the air bladders are relaxed and cannot fix the first lens 121 within the first frame 111. Therefore, the lens 121 can be easily replaced, for example, with lenses of different myopia prescriptions. After replacing the lens, the micro-solenoid valve and micro-air pump are opened. The micro-air pump inflates the four elastic air bladders, causing them to expand simultaneously and fix the lens in the center of the first frame 111. When pupillary distance adjustment is required, the lens position needs to be adjusted according to the required pupillary distance.
[0050] When the lens needs to be adjusted to the left, a miniature air pump inflates the elastic airbag on the right side, causing it to expand further. Simultaneously, the miniature solenoid valve corresponding to the elastic airbag on the left side opens, releasing the gas within it. It's important to note that the gas release rate in the right airbag must be synchronized with the inflation rate in the left airbag to prevent the lens from becoming loose. The upper and lower elastic airbags do not require inflation or deflation. Ultimately, the lens will shift to the left as a whole. Figure 7b As shown in the left figure. When the lens needs to be shifted to the right, the operation is reversed, and the adjustment result is as follows. Figure 7c As shown. The lens can also be adjusted upwards according to the user's usage habits (e.g., Figure 7d ), downwards (such as Figure 7e Position adjustment. In some other embodiments, the lens can also be adjusted to face the upper left, lower left, upper right, and lower right directions. Detailed features of this part are within the understanding of those skilled in the art and will not be listed or described in detail here.
[0051] Alternatively, please continue reading Figure 2The interpupillary distance adjustment device 130 in this embodiment may further include a control unit 135, which is connected to the pump body 132 and the solenoid valve (valve 134) and is used to control the working state of the pump body 132 and the solenoid valve. Specifically, the control unit 135 may be fixed or embedded in the temple of the frame 110 as shown in the figure, or it may be integrated into the pump body 132; no specific limitation is made here. The control unit 135 can be used to control the volume change of at least a portion of the elastic capsule, thereby causing the optical center of the first lens 121 and / or the second lens 122 to move, and the optical centers of the first lens 121 and the second lens 122 to be on the same horizontal line. The control unit 135 can also be used to keep the total volume of the medium in all elastic capsules constant, thereby maintaining the focal length between the first lens 121 and the second lens 122 constant. Detailed structure and adjustment process can be found in the relevant descriptions of the foregoing embodiments.
[0052] The glasses in this embodiment enable continuous adjustment of the interpupillary distance (IPD) of the lenses. This eliminates the need for VR glasses users to compensate for the inability to adjust IPD by increasing lens size or sacrificing display quality, resulting in a better user experience. Based on a micro-pump, micro-electromagnetic valve, and elastic airbag, the glasses feature a rationally designed structure that allows for rapid adjustment of the IPD. This structure is simpler and lighter than a motor-based structure, further enhancing the user experience. Furthermore, the glasses' simple structure and low cost contribute to this improved experience. Additionally, the airbag structure in this embodiment allows for quick lens replacement, facilitating the use of the same glasses by allowing more people to adopt the same style, thus expanding the application scenarios and target audience.
[0053] Optionally, please refer to the following as well. Figure 8 , Figure 8 This is a structural cross-sectional schematic diagram of an embodiment of the eyeglasses of this application. Unlike the previous embodiments, in this embodiment, the inner sidewall of the first frame 111 is provided with a first mounting groove 1110, a first controllable elastic body 1311 is disposed in the first mounting groove 1110, and the edge of the first lens 121 is embedded in the first mounting groove 1110; the first mounting groove 1110 serves to limit the first lens 121, so that the first lens 121 can only move within its extended plane; the inner sidewall of the second frame 112 is provided with a second mounting groove 1120, a second controllable elastic body 1312 is disposed in the second mounting groove 1120, and the edge of the second lens 122 is embedded in the second mounting groove 1120; the second mounting groove 1120 serves to limit the second lens 122, so that the second lens 122 can only move within its extended plane.
[0054] Please refer to the following: Figure 9 , Figure 9yes Figure 8 The embodiment shows a cross-sectional view of the eyeglasses in one working state of the interpupillary distance adjustment device, corresponding to the embodiment shown in Figure 7(d) where the lens position is moved upward. In this embodiment, the controllable elastomer expands or contracts within the mounting groove, driving the lens to move within its extension plane, ensuring the lens remains embedded within the mounting groove. Specifically, the upper and lower opposing elastic airbag structures (131) will be used as an example for explanation. Figure 9 In the intermediate state, the volume of the lower elastic airbag structure increases, while the volume of the upper elastic airbag structure decreases. Similarly, moving the lens to the other side controls the opposite direction. The deformation of the controllable elastic body 131 can be adjusted to allow the lens to detach from the mounting groove. Figure 9 In its neutral position, the user can remove the lens 120 by hand or with a specific clamping device, and it can be held in the mounting slot (such as...). Figure 8 (Mid-state).
[0055] Optionally, please refer to Figure 10 , Figure 10 This is a schematic diagram of the overall structure of another embodiment of the glasses in this application. The glasses in this embodiment can be VR or AR glasses. The glasses 100 also includes a display unit 140, which is fixed to the frame 110. In this embodiment, the display unit 140 can be disposed on the temple of the frame 110. In some other embodiments, the display unit 140 can also be disposed on the frame. The first lens 121 and the second lens 122 are configured to present a virtual reality or augmented reality environment under the control of the display unit 140; wherein, the display unit 140 can be a device such as an optical engine for projecting and emitting optical signals to the lenses.
[0056] In addition, the glasses in this embodiment may also include a control circuit board, a rechargeable battery, a speaker, and a wireless communication module, allowing the glasses to be used independently or in conjunction with other electronic devices (via wired or wireless connection). Detailed technical features in this regard are beyond the understanding of those skilled in the art and will not be elaborated upon here.
[0057] The above description is only a part of the embodiments of the present invention and does not limit the scope of protection of the present invention.
