[0047] In this embodiment of the invention, the lens assembly 100 is applied to smart glasses, which include a frame 200 and an imaging carrier 300 fixed to the frame 200. The lens assembly 100 includes:

[0048] The bracket 110 is provided with a first detachable connecting structure 130, which is used to detachably connect to the frame 200; and

[0049] Lens 120 is mounted on bracket 110 and located on the side of imaging carrier 300 close to the user's eye. Lens 120 is configured as a standard lens 120 with a preset shape.

[0050] In one embodiment of the present invention, the lens assembly 100 is applied to smart glasses. The smart glasses include a frame 200 and an imaging carrier 300. The user wears the smart glasses on their face through the frame 200 and obtains information such as video, images, and text through the imaging carrier 300. The lens assembly 100 includes a support 110 and a lens 120. The lens 120 is mounted on the support 110 and positioned on the side of the imaging carrier 300 closest to the user's eyes. The user's eyes look at the imaging carrier 300 through the lens 120. The lens 120 can be a myopia lens 120, a hyperopia lens 120, an astigmatic lens 120, a polarized lens 120, or a blue light blocking lens 120, etc., determined according to the user's vision and personal needs, ensuring that users who wear ordinary glasses daily can clearly obtain information from the imaging carrier 300. The support 110 is detachably connected to the frame 200 through a first detachable connection structure 130, making it easy to install and remove the lens assembly 100, thus improving the replacement efficiency of the lens assembly 100. By providing a detachable lens assembly 100 to the frame 200, users can replace the lens assembly 100 with different functions according to their individual needs, thereby meeting different usage requirements. For example, for a nearsighted user, when using smart glasses indoors, the user only needs a regular nearsighted lens 120, while when using smart glasses outdoors, the user may need a nearsighted lens 120 with UV protection to protect their eyes. On the other hand, during the lifespan of the smart glasses, the user's vision may change, at which point the user only needs to replace the lens assembly 100, reducing the cost of using smart glasses. Furthermore, for family users, the detachable lens assembly 100 allows one smart glasses to meet the usage needs of multiple people with different vision conditions. Moreover, the lens assembly 100 can be installed and removed simply by providing a mounting position on the frame 200 corresponding to the first detachable connection structure 130, making the lens assembly 100 suitable for different types and specifications of smart glasses. For example, the same lens assembly 100 can be installed on both AR glasses and VR glasses, thereby improving the ease of use of the lens assembly 100. The lens 120 is configured as a standard lens 120 with a preset shape, that is, the lens 120 of the lens assembly 100 has a uniform shape, the shape of the lens 120 is standardized and does not change due to changes in the shape of the frame 200 and the imaging carrier 300, thereby reducing the manufacturing cost of the lens assembly 100 and improving the production efficiency of the lens assembly 100.

[0051] In this embodiment, the first detachable connection structure 130 can be implemented by snap-fit ​​or screw connection. The frame 200 has multiple mounting positions corresponding to the first detachable connection structure 130. These mounting positions allow adjustment of the position of the lens assembly 100 on the frame 200, such as adjusting the height of the lens assembly 100 on the frame 200, thereby adjusting the relative position of the lens 120 and the imaging carrier 300. This makes it easier for the lens assembly 100 to accommodate different facial features of users, such as nose bridge height and eye spacing, thus improving user comfort when using smart glasses.

[0052] Optionally, the bracket 110 includes a support portion 111 and two mounting portions 112 located at opposite ends of the support portion 111. The mounting portions 112 are provided with a first detachable connection structure 130 for detachable connection with the eyeglass frame 200.

[0053] Reference Figure 3 In this embodiment, the bracket 110 includes a support portion 111 and mounting portions 112 at both ends of the support portion 111. The two lenses 120 of the lens assembly 100 are respectively fixed on one mounting portion 112. The lens assembly 100 becomes a whole through the bracket 110, making the structure of the lens assembly 100 more stable and reducing the possibility of damage to the lens assembly 100. The first detachable connection structure 130 is disposed on the mounting portion 112 and is detachably connected to the frame 200 through the two mounting portions 112, improving the connection strength between the bracket 110 and the frame 200 and reducing the possibility of the lens assembly 100 falling off the frame 200.

[0054] Optionally, the mounting section 112 has an open mounting space in which the lens 120 is mounted.

[0055] In this embodiment, the lens 120 is mounted in the mounting portion 112, which has an open mounting space, allowing the bracket 110 to fix the lens 120 in a semi-frame or frameless manner. Figure 3 The image shown is in frameless format, as follows: Figure 5 The image shown is in a semi-rimless form. When the lens assembly 100 is installed on smart glasses of different types or specifications, the obstruction of the image carrier 300 by the bracket 110 can be reduced, thereby increasing the applicability of the lens assembly 100. Furthermore, the semi-rimless or frameless bracket 110 is easier to install and remove from the lens 120, making it easier for users to replace the lens 120.

[0056] Optionally, the first detachable connection structure 130 includes a first snap-fit ​​structure 131. Each mounting part 112 is provided with the first snap-fit ​​structure 131 on the side near the support part 111. The first snap-fit ​​structure 131 snaps into the frame 200 so that the mounting part 112 is detachably connected to the frame 200.

[0057] Reference Figure 7 and Figure 8 In this embodiment, the mounting part 112 and the frame 200 are detachably connected via a first snap-fit ​​structure 131, which is simple in structure and easy to assemble and disassemble. The first snap-fit ​​structure 131 is located on the side of the mounting part 112 near the support part 111. The mounting position on the frame 200 corresponding to the first snap-fit ​​structure 131 is close to the middle part of the frame 200, located above the user's nose bridge. This makes it less susceptible to interference from the temples during assembly and disassembly, and makes the operation of assembling and disassembling the lens assembly 100 more convenient.

[0058] Optionally, the first snap-fit ​​structures 131 on the two mounting portions 112 are disposed opposite to each other; and / or,

[0059] The first snap-fit ​​structure 131 includes a snap fastener 1311 or a snap hole 201 provided on the mounting part 112, so as to snap and cooperate with the corresponding snap hole 201 or snap fastener 1311 provided on the frame 200.

[0060] Reference Figure 7 and Figure 8 In this embodiment, each mounting part 112 has a sidewall facing the other mounting part 112. The sidewalls of the two mounting parts 112 face each other to form a clamping space for clamping the eyeglass frame 200. Each sidewall is provided with a first snap-fit ​​structure 131. The two first snap-fit ​​structures 131 are arranged opposite each other and snap-fit ​​with the eyeglass frame 200 to prevent the eyeglass frame 200 from falling out of the clamping space, thus limiting the separation of the bracket 110 and the eyeglass frame 200 and further improving the connection strength between the bracket 110 and the eyeglass frame 200. On the other hand, the first snap-fit ​​structures 131 on the two mounting parts 112 are arranged opposite each other, making the entire bracket 110 mirror symmetrical from left to right, which reduces the manufacturing difficulty of the bracket 110 and improves the aesthetics of the bracket 110.

[0061] In this embodiment, the first snap-fit ​​structure 131 can be a buckle 1311 provided on the mounting part 112, which snaps into the corresponding buckle hole 201 provided on the frame 200. Alternatively, the first snap-fit ​​structure 131 can be a buckle hole 201 provided on the mounting part 112, which snaps into the corresponding buckle 1311 provided on the frame 200. The buckle 1311 and buckle hole 201 have a simple structure, are easy to manufacture, and have low processing costs.

[0062] Optionally, the first detachable connection structure 130 further includes a second snap-fit ​​structure 132, which is located at the end of the mounting portion 112 away from the support portion 111 and snaps into the frame 200.

[0063] Reference Figure 7 and Figure 9In this embodiment, the second snap-fit ​​structure 132 is disposed at the end of the mounting portion 112 away from the support portion 111. The second snap-fit ​​structure 132 and the first snap-fit ​​structure 131 are distributed on the mounting portion 112, further enhancing the connection strength between the bracket 110 and the frame 200, reducing the possibility of the lens assembly 100 falling off the frame 200, and making it easy for the user to distinguish the mounting positions of the frame 200 corresponding to the first snap-fit ​​structure 131 and the second snap-fit ​​structure 132, reducing assembly difficulty and improving assembly efficiency. The second snap-fit ​​structure 132 can be a buckle 1311 disposed on the mounting portion 112, which engages with a corresponding buckle hole 201 disposed on the frame 200. Alternatively, the second snap-fit ​​structure 132 can be a buckle hole 201 disposed on the mounting portion 112, which engages with a corresponding buckle 1311 disposed on the frame 200. The engagement structure of the buckle 1311 and the buckle hole 201 is simple, easy to manufacture, and has low processing cost. Specifically, in this embodiment, the first snap-fit ​​structure 131 and the second snap-fit ​​structure 132 adopt the same snap-fit ​​1311 form, making the snap-fit ​​structure on the bracket 110 more uniform and reducing the manufacturing difficulty and production cost of the bracket 110.

[0064] Optionally, a second detachable connection structure 140 is provided between the lens 120 and the mounting part 112 to allow the lens 120 and the mounting part 112 to be detachably connected.

[0065] Reference Figure 2 In this embodiment, the lens 120 is detachably connected to the mounting part 112 through the second detachable connection structure 140. The second detachable connection structure 140 can be implemented by means of snap-fit ​​or screw connection, which facilitates the disassembly and replacement of the lens 120.

[0066] Optionally, the second detachable connection structure 140 includes a flexible member 141, which is sleeved on the lens 120 and both ends of the flexible member 141 are fixed to the mounting portion 112 so that the lens 120 is fixed to the mounting portion 112.

[0067] Reference Figure 10 In this embodiment, the mounting part 112 is fixed to the mounting part 112 of the bracket 110 via a flexible member 141. The flexible member 141 is sleeved on the outer peripheral wall of the lens 120, and both ends of the flexible member 141 are fixed to the mounting part 112, thereby fixing the lens 120 to the mounting part 112. The flexible member 141 can be in the form of a wire, chain, etc. Specifically, in this embodiment, the bracket 110 is in the form of a semi-frame, and the flexible member 141 is generally made of transparent plastic wire. The semi-frame bracket 110 and the lens 120 are connected by the flexible member 141, which not only ensures a firm connection but also improves the aesthetics of the lens assembly 100.

[0068] Optionally, the outer peripheral wall of the lens 120 is provided with a receiving groove 121, and the flexible member 141 is disposed within the receiving groove 121; and / or,

[0069] The second detachable connection structure 140 also includes a mounting hole 1123 provided in the mounting part 112, and the two ends of the flexible member 141 are tied to the mounting hole 1123.

[0070] Combination Figures 10 to 11 In this embodiment, a receiving groove 121 is provided on the outer peripheral wall of the lens 120. When the flexible member 141 is sleeved on the outer periphery of the lens 120 to fix the lens 120 to the mounting part 112, the flexible member 141 is not easy to move in the receiving groove 121, which improves the firmness of the flexible member 141 on the outer periphery of the lens 120 and reduces the possibility of the flexible member 141 separating from the lens 120, thereby reducing the possibility of the lens 120 falling off. In addition, the flexible member 141 is hidden in the receiving groove 121 on the outer peripheral wall of the lens 120, making it difficult to find, which further improves the aesthetics of the lens assembly 100.

[0071] Combination Figures 7 to 10 In this embodiment, mounting holes 1123 are provided on the mounting part 112, and the two ends of the flexible member 141 are tied to the mounting holes 1123. This makes it easier to assemble and disassemble the flexible member 141 and the mounting part 112, thereby reducing the difficulty of assembling and disassembling the lens 120 and facilitating the replacement of the lens 120.

[0072] Optionally, the second detachable connection structure 140 includes screws, and the lens 120 is fastened to the mounting part 112 by screws.

[0073] Reference Figure 2 In this embodiment, mounting holes are provided on the lens 120 and the mounting part 112 respectively. The mounting holes of the lens 120 and the mounting part 112 are connected by screws, resulting in high connection strength and making it difficult for the lens 120 and the bracket 110 to separate. Specifically, in this embodiment, the bracket 110 is frameless, and the screw connection reduces the possibility of the lens 120 falling off the bracket 110 and improves the aesthetics of the lens assembly 100. When replacing different lenses 120, the first detachable connection structure 130 between the bracket 110 and the frame 200 does not need to be disassembled; only the screws between the lens 120 and the mounting part 112 need to be removed or installed, making lens replacement simpler and faster.

[0074] Optionally, the mounting part 112 includes a frame segment 1121 and a linear segment 1122. The frame segment 1121 is connected to the support part 111. One end of the linear segment 1122 is fixed to the end of the frame segment 1121 away from the support part 111. The other end of the linear segment 1122 extends in a direction away from the frame segment 1121. The linear segment 1122 is fastened to the lens 120 by screws.

[0075] Reference Figure 4 In this embodiment, the mounting part 112 includes a frame segment 1121 and a linear segment 1122. The frame segment 1121 connects the support part 111 and the linear segment 1122. The first snap-fit ​​structure 131 is provided in the frame segment 1121. The frame segment 1121 has high strength, which makes the bracket 110 itself and the connection between the bracket 110 and the frame 200 more stable. The two ends of the linear segment 1122 are connected to the lens 120 by screws. The linear segment 1122 is small in size, which reduces the obstruction of the lens 120 by the bracket 110, improves the convenience of the user when using the lens assembly 100, and reduces the obstruction of the imaging carrier 300 by the bracket 110, which improves the adaptability of the lens assembly 100 when applied to smart glasses of different specifications. Specifically, in this embodiment, the frame segment 1121 includes a first sub-frame 11211 and a second sub-frame 11212. The second sub-frame 11212 connects one end of the linear segment 1122 and the first sub-frame 11211. One end of the first sub-frame 11211 is connected to the support portion 111 and is provided with a first snap-fit ​​structure 131. The other end of the first sub-frame 11211 extends away from the imaging carrier 300. One end of the second sub-frame 11212 is connected to the end of the first sub-frame 11211 away from the imaging carrier 300. The other end of the second sub-frame 11212 extends away from the support portion 111, so that the first sub-frame 11211 and the second sub-frame 11212 form a corner structure, making the entire frame segment 1121 more three-dimensional and having higher structural strength; combined with Figures 1 to 2 The lens 120 is positioned between the linear segment 1122 and the imaging carrier 300, making the structure of the entire lens assembly 100 more compact and easier to install with the frame 200. It also avoids the lens 120 being too close to the user's eyes when the user is using smart glasses.

[0076] Optionally, the lens assembly 100 also includes a nose pad 151, which is disposed on the support 110.

[0077] In this embodiment, the nose pad 151 is disposed on the bracket 110 of the lens assembly 100. The lens assembly 100 with the nose pad 151 provides a similar physical sensation to the user's ordinary glasses worn daily. It is equivalent to adding smart glasses to the outside of the user's ordinary glasses, which is more in line with the user's usage habits and allows the user to adapt to the wearing experience of smart glasses more quickly.

[0078] Optionally, the lens assembly 100 also includes a nose support 152, one end of which is fixed to the support 111, and the other end of which extends in a direction away from the imaging carrier 300. The nose pad 151 and the nose support 152 are detachably connected.

[0079] Reference Figure 12In this embodiment, one end of the nose support 152 is fixed to the support 111, and can be snapped into the support 111 or integrally formed. The other end of the nose support 152 is provided with a nose pad 151, which is fixed by screws or snap-fitting. The nose support 152 facilitates the installation of the nose pad 151, and the position of the nose pad 151 can be finely adjusted by adjusting the shape of the nose support 152, thereby improving the user's wearing comfort.

[0080] The present invention also proposes a smart glasses, which includes the lens assembly 100 described above. The specific structure of the lens assembly 100 is as described in the above embodiments. Since the smart glasses adopt all the technical solutions of all the above embodiments, they possess at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. Specifically, the frame 200 is provided with a mounting position corresponding to the first detachable connection structure 130, thereby realizing the detachment and assembly of the lens assembly 100. The structure is simple and conducive to the lightweight and miniaturization of the smart glasses. Furthermore, the detachability of the lens assembly 100 from the frame 200 facilitates both wiping the lens 120 of the lens assembly 100 and wiping the imaging carrier 300.

[0081] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention.
