The first crossbeam and the second crossbeam are movable relative to each other along the height direction of the frame. The first support assembly and the second support assembly are both disposed on the beam assembly. The eyeglasses have a first state and a second state. In the first state, the first crossbeam and the second crossbeam are close to each other, and at least one of the first support assembly and the second support assembly is movable along the length direction of the frame. In the second state, the first crossbeam and the second crossbeam are far apart, and the first crossbeam and the second support assembly fasten the first support assembly and the second support assembly.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this disclosure, but are not intended to limit the scope of this disclosure.

[0019] In the description of this disclosure, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0020] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0021] Figure 1 The diagram illustrates the structure of eyeglasses 100 according to an embodiment of this disclosure. Eyeglasses 100 includes a first support assembly 2a and a second support assembly 2b. The first support assembly 2a and the second support assembly 2b can move relative to each other along the width direction of eyeglasses 100 to adjust their spacing. The first support assembly 2a and the second support assembly 2b correspond to the wearer's two eyes, respectively. After the user wears eyeglasses 100, the first support assembly 2a and the second support assembly 2b can be positioned in front of the wearer's eyes. Since different users have different interpupillary distances, the adjustable spacing between the first support assembly 2a and the second support assembly 2b of eyeglasses 100 will be compatible with a wider range of users.

[0022] It should be noted that the width direction of the glasses can be... Figure 1 The direction indicated by arrow L in the image, the height direction of the glasses can be understood as... Figure 1 The direction indicated by the middle arrow H.

[0023] The glasses 100 disclosed herein can be ordinary glasses, such as myopia glasses, hyperopia glasses, or sunglasses, etc. The glasses 100 can also be smart glasses 100, such as VR glasses (Virtual Reality), AR glasses 100 (Augmented Reality), and MR glasses (Mixed Reality), etc., with display functions; for example, when the glasses 100 are ordinary glasses 100, optical lenses (such as myopia lenses, hyperopia lenses, or sunglasses) are provided on both the first support assembly 2a and the second support assembly 2b, and external light enters the human eye after passing through the optical lenses.

[0024] When the glasses 100 are smart glasses 100, optical systems for imaging can be installed on both the first support assembly 2a and the second support assembly 2b. Taking AR as an example, Figure 8A schematic diagram of an optical system for eyeglasses that can be used in embodiments of this disclosure is shown. The eyeglasses 100 contain this optical system, which may include an image source component 61 and optical components. The image source component 61 emits light capable of forming an image, and the optical components modify the light path emitted by the image source component 61, projecting the light towards a first side of the image source component 61, so that when the eyeglasses 100 are worn on the user's head, the light can be projected into the user's eyes 200, thereby forming an image in the user's eyes. The optical components may include a flat lens 62 and a curved lens 63. The image source component 61 projects light vertically, the flat lens 62 refracts the light emitted by the image source component 61 and projects the light towards a second side, and the curved lens 63 reflects the light projected by the flat lens 62 and projects the light towards the first side. The light can pass through the flat lens 62 and, when the user wears the eyeglasses 100, is projected into the user's eyes, thereby forming a virtual image in the user's field of vision. Understandably, optical systems are not limited to the types of optical systems described above, but can also include optical systems such as stereo beam splitters, prisms, freeform surface optical elements, and optical waveguide elements.

[0025] Figure 2 This diagram illustrates the state of the glasses with the nose pads installed according to an embodiment of the present disclosure, in conjunction with... Figure 1 and Figure 2 As shown, the eyeglasses 100 may include a beam assembly 1, which has a first beam 11 and a second beam 12. The first beam 11 and the second beam 12 are movable relative to each other along the height direction of the frame 4. For example, the first beam 11 is fixedly connected to the frame 4, and the second beam 12 is movable relative to the first beam 11 along the height direction of the frame 4. A first support assembly 2a and a second support assembly 2b are both disposed on the beam assembly 1. The eyeglasses 100 may have a first state and a second state. In the first state, such as... Figure 1 As shown, the first crossbeam 11 and the second crossbeam 12 are close together, and at least one of the first support assembly 2a and the second support assembly 2b can move along the length direction of the frame 4 of the glasses 100 to adjust the distance between the first support assembly 2a and the second support assembly 2b to meet the needs of different users. In the second state, as... Figure 2 As shown, the first crossbeam 11 and the second crossbeam 12 are far apart. The first crossbeam 11 and the second crossbeam 12 fasten the first support assembly 2a and the second support assembly 2b. The positions of the first support assembly 2a and the second support assembly 2b are fixed, and the glasses 100 are in a state where the interpupillary distance is adjusted, ready for the user to wear. (Refer to...) Figure 1 and Figure 2 As shown, the terms "closer" and "farther" described in the first and second states refer to the relative states of the first crossbeam 11 and the second crossbeam 12 along the height direction of the frame 4.

[0026] In the second state, the distance between the first crossbeam 11 and the second crossbeam 12 increases, allowing them to fit tightly with the support assembly. This increases the friction between the crossbeam assembly 1 and the support assembly, making it less likely for the first support assembly 2a and the second support assembly 2b to slide along the length of the crossbeam assembly 1. In the first state, the distance between the first crossbeam 11 and the second crossbeam 12 is small, preventing them from fitting tightly with the support assembly. The friction between the support assembly and the crossbeam assembly 1 is also small, allowing the first support assembly 2a and the second support assembly 2b to slide easily to adjust their distance.

[0027] For example, with the first support assembly 2a and the second support assembly 2b disposed in the crossbeam assembly 1, at least one of the first support assembly 2a and the second support assembly 2b may have a gap with the crossbeam assembly 1 along the height direction of the frame 4. In a first state, the gap between at least one of the first support assembly 2a and the second support assembly 2b and the crossbeam assembly 1 is relatively large, allowing the first support assembly 2a and / or the second support assembly 2b to slide along the length direction of the crossbeam assembly 1. In a second state, the gap between at least one of the first support assembly 2a and the second support assembly 2b and the crossbeam assembly 1 is very small, negligible, preventing the first support assembly 2a and / or the second support assembly 2b from sliding along the length direction of the crossbeam assembly 1. It is understood that even the aforementioned relatively large gap is only on the order of a few tenths of a millimeter.

[0028] When the distance between the first support assembly 2a and the second support assembly 2b of the glasses 100 does not match the user's preference, the glasses 100 can be operated to adjust it to a first state. In this state, at least one of the two first support assemblies 2a and the second support is movable. The distance between the first support assembly 2a and the second support assembly 2b can be adjusted by moving either support assembly or by moving both support assemblies simultaneously. After adjusting the distance between the first support assembly 2a and the second support assembly 2b, the glasses 100 can be operated to adjust it to a second state, fixing the positions of the first support assembly 2a and the second support to prevent relative movement and positional changes.

[0029] Figure 7 This diagram illustrates the structure of eyeglasses provided in an embodiment of the present disclosure. The eyeglasses 100 may include a frame 4, which is the main structure of the eyeglasses 100 and serves to support various structural components. Temples 5 may be provided at both ends of the frame 4 along its width. A beam assembly 1 is disposed on the frame 4. A shell structure may be provided on the frame 4, forming a cavity. The first support assembly 2a and the second support assembly 2b may be at least partially accommodated within the cavity of the shell structure. Two lens frames may also be provided on the frame 4, and lenses may be disposed on the lens frames. The support assemblies and the optical system may be located inside the lenses, where "inner side" can be understood as the side where the temples extend.

[0030] In some possible embodiments, such as Figure 2 As shown, the glasses 100 may also include a detachable nose pad 3, in which the nose pad 3 is connected to either the frame 4 or the beam assembly 1 in the second state, such that the first beam 11 and the second beam 12 are separated.

[0031] In the first state, the nose pad 3 and the main body of the glasses are separated. After adjusting the positions of the first support assembly 2a and the second support assembly 2b, the nose pad 3 can be installed. The nose pad 3 can act on the crossbeam assembly 1, so that the first crossbeam 11 and the second crossbeam 12 are far apart, increasing the distance between the first crossbeam 11 and the second crossbeam 12, thereby fixing the first support assembly 2a and the second support assembly 2b.

[0032] This disclosed implementation scheme is well-suited to customer user experience. Different users may have different interpupillary distances (IPDs), and generally, IPD adjustment is only necessary when the user changes. Similarly, different users may have different nose bridge heights, often requiring simultaneous replacement of the nose pad 3. Therefore, when adjusting the IPD, the original nose pad 3 can be removed first, and then the distance between the first support assembly 2a and the second support assembly 2b can be adjusted. After adjusting the distance between the two support assemblies, the new nose pad 3 can be replaced. After installing the new nose pad 3, the positions of the first support assembly 2a and the second support assembly 2b are simultaneously locked. The nose pad 3 and the support assemblies can be fixed simultaneously through a series of relatively simple operations.

[0033] In some possible embodiments, see Figure 1 and Figure 2 As shown, the first crossbeam 11 can be fixedly connected to the frame 4, while the second crossbeam 12 can be movably fitted with the frame 4. A mounting portion is provided on either the frame 4 or the first crossbeam 11, and a nose pad clearance portion 111 can be provided on the first crossbeam 11. In the second state, the nose pad 3 is fixedly fitted with the mounting portion, and the nose pad bracket of the nose pad 3 can pass through the nose pad clearance portion 111 and abut against the second crossbeam 12, thereby widening the distance between the first crossbeam 11 and the second crossbeam 12. For example, the nose pad clearance portion 111 can be located at the middle position along the length direction of the first crossbeam 11.

[0034] In some possible embodiments, such as Figure 1 and Figure 2As shown, an elastic element 121 can be provided on the second crossbeam 12. In the second state, the nose pad 3 elastically abuts against the elastic element 121, and an external force is applied to the second crossbeam 12 through the elastic element 121. The elastic element 121 can be a structure such as foam, rubber pad, or spring. By providing the elastic element 121, the nose pad 3 and the second crossbeam 12 are not rigidly coupled, but elastically coupled, providing a flexible feel, reducing wear between the nose pad 3 and the second crossbeam 12, and extending the reliability and service life of the glasses 100.

[0035] In some possible embodiments, both the first support assembly 2a and the second support assembly 2b include a support portion 23 and a limiting portion 21. In the second state, as... Figure 2 As shown, the first crossbeam 11 and the support portion 23 are fastened together, and the second crossbeam 12 and the limiting portion 21 are fastened together to fix the first bracket assembly 2a and the second bracket assembly 2b.

[0036] The support portion 23 and the limiting portion 21 can be arranged sequentially along the height direction of the frame 4. The support portion 23 can be located on the side of the first crossbeam 11 away from the second crossbeam 12, and the limiting portion 21 can be located on the side of the second crossbeam 12 away from the first crossbeam 11. In the second state, the distance between the first crossbeam 11 and the second crossbeam 12 increases, the first crossbeam 11 abuts against the support portion 23, and the second crossbeam 12 abuts against the limiting portion 21, thereby increasing the frictional resistance between the bracket assembly and the crossbeam assembly 1, so that the positions of the first bracket assembly 2a and the second bracket assembly 2b are fixed and will not easily move along the crossbeam assembly 1.

[0037] In some possible embodiments, at least a portion of the first crossbeam 11 and the second crossbeam 12 are located between the support portion 23 and the limiting portion 21, so that the limiting portion 21 and the support portion 23 can have portions that are in close contact with the second crossbeam 12 and the first crossbeam 11, respectively, ensuring that the first support assembly 2a and the second support assembly 2b can be fastened to the crossbeam assembly 1.

[0038] The first crossbeam 11 can be entirely located between the support portion 23 and the limiting portion 21, meaning that the first crossbeam 11 does not have a structure for accommodating the support portion 23. Alternatively, the first crossbeam 11 can be partially located between the support portion 23 and the limiting portion 21, for example, by providing a recessed structure or a hollow portion, in which case the support portion 23 can be at least partially accommodated, thereby reducing the height of the frame 4. Similarly, the second crossbeam 12 can be entirely located between the support portion 23 and the limiting portion 21, meaning that the second crossbeam 12 does not have a structure for accommodating the limiting portion 21. Alternatively, the second crossbeam 12 can be partially located between the support portion 23 and the limiting portion 21, for example, by providing a recessed structure or a hollow portion, in which case the limiting portion 21 can be at least partially accommodated, thereby reducing the height of the frame 4.

[0039] In some possible embodiments, the support portion 23 and the limiting portion 21 are connected, and the limiting portion 21 is movable relative to the support portion 23 to adjust the distance between the limiting portion 21 and the support portion 23.

[0040] For example, the limiting part 21 can be connected to a stud 22, and the supporting part 23 can have a threaded groove, and the stud 22 can be threadedly connected to the stud 22. Rotating the limiting part 21 can cause the stud 22 to be screwed into or out of the threaded groove of the supporting part 23, thereby causing the limiting part 21 to move closer to or further away from the supporting part 23, so as to adjust the distance between the limiting part 21 and the supporting part 23.

[0041] Before the nose pad 3 is installed, the stud 22 can pass through the first crossbeam 11 and the second crossbeam 12 and be threaded onto the support part 23. Each support part 23 can cooperate with at least two limiting parts 21 to improve the strength and stability of the assembly structure. Using the stud 22 makes it easy to control the gap between the limiting part 21 and the first crossbeam 11. For example, the stud 22 does not need to be completely screwed into the threaded groove. For example, the operation can be to first rotate the limiting part 21 so that the stud 22 is locked into the threaded groove, and then screw it back a little bit to ensure that the locking force of the limiting part 21 is very small at this time, so that a small gap is maintained between the limiting part 21 and the first crossbeam 11. For example, the gap Δ between the limiting part 21 and the first crossbeam 11 is 0.1mm. At this time, the support part 23 can slide relative to the crossbeam assembly 1 with small sliding damping, and the user can manually adjust the interpupillary distance by moving the support part 23.

[0042] When the glasses 100 are smart glasses 100, the glasses 100 have an optical system, and the support portions 23 on the first bracket assembly 2a and the second bracket assembly 2b can respectively mount the optical system. The principle of the optical system has been explained in detail above and will not be repeated here.

[0043] like Figure 2 and Figure 3As shown, one of the first crossbeam 11 and the second crossbeam 12 is provided with a guide groove 113, and the other is provided with a guide post 122. The guide post 122 is slidably inserted into the guide groove 113, and the guide post 122 and the guide groove 113 extend along the height direction of the mirror frame 4. In the second state, at least the end of the guide post 122 is located in the guide groove 113.

[0044] The plug-in structure of the guide post 122 and the guide groove 113 restricts the first crossbeam 11 and the second crossbeam 12 to move only in the direction of the height of the glasses 100, so as to adjust the distance between the two.

[0045] The guide posts 122 and guide grooves 113 can be arranged in different ways. In one arrangement, as shown in Figure 2, the guide posts 122 are located on both sides of one of the first crossbeams 11 and 12 along the length direction, and the guide grooves 113 are located on both sides of the other crossbeam 11 and 12 along the length direction. Both ends of the first crossbeam 11 and 12 are positioned and guided by the guide grooves 113 and guide posts 122, which facilitates synchronous movement of both sides of the first crossbeam 11 and 12 and prevents them from tilting. In another arrangement, the guide posts 122 are located at the middle of one of the first crossbeams 11 and 12, and the guide grooves 113 are located at the middle of the other crossbeam 11 and 12. In this case, the guide posts 122 and guide grooves 113 are not required at the ends of the first crossbeam 11 and 12. When the guide groove 113 and the guide column 122 are located in the middle of the crossbeam, the size of the guide groove 113 and the guide column 122 can be increased accordingly, such as the outer diameter, which is conducive to the smooth movement of the second crossbeam 12 relative to the first crossbeam 11 and is not easy to tilt.

[0046] In some possible embodiments, such as Figure 2 and Figure 3 As shown, at least one of the first crossbeam 11 and the second crossbeam 12 is provided with a sliding groove a, which extends along the length of the crossbeam assembly 1 and limits the range of movement of the first support assembly 2a and the second support assembly 2b.

[0047] Two sliding grooves a can be provided on the first crossbeam 11 or the second crossbeam 12. The two sliding grooves a are arranged sequentially along the length direction of the crossbeam assembly. The two sliding grooves a can respectively limit the movement range of the first support assembly 2a and the second support assembly 2b.

[0048] Figure 6The diagram shows a comparison of the interpupillary distance adjustment (ΔPD) of the glasses provided in this embodiment, with values ​​of 0, maximum, and minimum. The slide a limits the movement range of each support assembly to 0mm to 6mm. That is, the binocular interpupillary distance adjustment range formed by the first support assembly 2a and the second support assembly 2b can reach 0mm to 12mm. This interpupillary distance adjustment range can basically cover all adults and is compatible with all customers.

[0049] In some possible embodiments, a groove a can be provided on the second crossbeam 12, and the limiting part 21 can be accommodated within the groove a. The length of the groove a limits the range of movement of the limiting part 21. Alternatively, a groove a can be provided on the first crossbeam 11, and the support part 23 can be partially confined within the groove a. The groove a on the first crossbeam 11 limits the sliding range of the support part 23. Alternatively, both the first support assembly 2a and the second support assembly 2b include a connecting part, which connects the support part 23 and the limiting part 21 respectively. A groove a can be provided on at least one of the first crossbeam 11 and the second crossbeam 12, and the connecting part extends through the groove a, which limits the sliding range of the connecting part. This connecting part can be the stud 22 mentioned above.

[0050] In some possible embodiments, the relative movement distance between the first crossbeam 11 and the second crossbeam 12 is 0.05 mm to 0.3 mm. The limiting distance of relative movement between the first crossbeam 11 and the second crossbeam 12 is small, requiring only a 1 mm to 2 mm increase in the size of the optical system. This avoids excessive increases in the height of the optical system due to the addition of the interpupillary distance adjustment structure, and does not significantly increase the height of the frame 4 of the glasses 100, thus minimizing the increase in the size and weight of the glasses 100.

[0051] Figure 4 This diagram illustrates the structure of the eyeglasses with interpupillary distance scale markings provided in an embodiment of the present disclosure. Figure 5 This diagram illustrates another structural schematic of the eyeglasses with an interpupillary distance (IPD) scale marking section provided in an embodiment of this disclosure. An IPD scale marking section 112 can be provided on the first crossbeam 11, extending along the length of the first crossbeam 11. The movement distance of the support assembly can be precisely adjusted according to the IPD scale marking section 112. The IPD scale marking sections 112 can be symmetrically provided on both sides of the first crossbeam 11 to facilitate precise quantitative adjustment of the positions of the two support assemblies. The IPD scale marking section 112 can be located on either side of the support assembly.

[0052] The glasses 100 provided in this disclosure have a simple structure and are lighter than ordinary adjustable pupillary distance glasses 100. The assembly process of the glasses 100 is relatively simple, and the assembly steps may include the following:

[0053] Step 1: Assemble the support part 23 with the first crossbeam 11;

[0054] A slot can be provided on the first crossbeam 11, and the support part 23 can be partially inserted into the slot to pre-position the support part 23 and the first crossbeam 11.

[0055] Step 2: Assemble the second crossbeam 12 and the first crossbeam 11 so that the guide post 122 of one is inserted into the guide groove 113 of the other;

[0056] Step 3: Pass the stud 22 of the connecting limiting part 21 through the first crossbeam 11 and the second crossbeam 12 and thread it onto the support part 23, control the preload of the stud 22, or make a certain gap between the limiting part 21 and the second crossbeam 12.

[0057] Step 4: Assemble the first crossbeam 11 and the second crossbeam 12 onto the frame 4 of the eyeglasses 100;

[0058] Step 5: Quantitatively adjust the distance between the first support assembly 2a and the second support assembly 2b according to the interpupillary distance scale marking section 112;

[0059] Step 6: Select a suitable nose pad 3 and install the nose pad 3 to fix the position of the first support assembly 2a and the second support assembly 2b.

[0060] Understandably, step 5 is a step that only exists in eyeglasses with a pupillary distance scale marking section 112. If the eyeglasses do not have a pupillary distance scale marking section 112, this step can be omitted.

[0061] The above description has been given for purposes of illustration and description. Furthermore, this description is not intended to limit the embodiments of this disclosure to the forms disclosed herein. Although numerous exemplary aspects and embodiments have been discussed above, those skilled in the art will recognize certain variations, modifications, alterations, additions, and sub-combinations therein.
