[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in the first embodiment of this utility model, a smart glasses with better weight distribution and privacy protection includes a support element 1 that can be worn on the head. One side of the support element 1 is provided with a rotatable lens support 2. An optical display module for displaying digital content is mounted on the lens support (2). In this embodiment, the optical display module is a waveguide lens 3.

[0030] In the first embodiment, the supporting element 1 includes an arc-shaped support plate 11, a first elastic bandage 12, and a first limiting pin 13 placed side by side. The shape of each arc-shaped support plate 11 is adapted to the jawbone of the face. A first elastic bandage 12 and a second elastic bandage 14 are provided between adjacent arc-shaped support plates 11. The first elastic bandage 12 and the second elastic bandage 14 are respectively attached to the occipital bone and the frontal bone. The lens support 2 is hinged to the side wall of the arc-shaped support plate 11 through the first limiting pin 13.

[0031] It should be noted that: the lens support 2 is an arc-shaped frame and the electronic components are installed inside the lens support 2. The microphone can be integrated on the side of the lens support 2 near the jawbone of the face. The processor board for processing data and the battery module for powering the smart glasses can be integrated inside the lens support 2. Each lens support 2 is equipped with a miniature camera 5 facing forward for taking pictures or recording images.

[0032] The structure of the optical waveguide lens 3 typically includes an optical waveguide core and a cladding. The light propagation path is controlled by the refractive index design. As the "optical combiner" of AR glasses, the optical waveguide superimposes virtual images with ambient light to achieve a perspective effect that blends virtual and real elements, ensuring that users can observe both virtual and real content simultaneously.

[0033] During wear, the user tightly attaches the first elastic bandage 12 and the second elastic bandage 14 to the occipital and frontal bones respectively, relieving pressure on the bridge of the head. Instead, the head supports the lens support 2 and the waveguide lens 3. This structural design minimizes discomfort and pain associated with prolonged wear on the bridge of the nose, making it suitable for extended periods. Furthermore, using the skull as a load-bearing structure allows the smart glasses to have a greater load-bearing limit (exceeding the comfort load-bearing limit of traditional nose-pad smart glasses), enabling them to support more complex functional modules (such as large batteries and high-performance processors) to improve battery life and computing power. The elastic design of the first and second elastic bandages 12 and 14 adapts to different head shapes, enhancing versatility.

[0034] In the first embodiment, each of the first limiting pins 13 has a plurality of limiting protrusions 131 on its surface, and the end of each of the first limiting pins 13 is fixedly installed on the side wall of the arc-shaped support plate 11. The end of the lens support 2 is provided with a limiting groove 21 adapted to the limiting protrusions 131.

[0035] Both the limiting boss 131 and the limiting groove 21 are annularly arranged. Whenever the lens support 2 is rotated, the limiting boss 131 on the first limiting pin 13 is in a fixed state, while the limiting groove 21 of the lens support 2 continuously re-engages with the new limiting boss 131 as the lens support 2 rotates and adjusts its position. After engagement, the frictional force generated between the limiting boss 131 and the limiting groove 21 supports the lens support 2 in the rotated position.

[0036] This structure enables the angle adjustment of the miniature camera 5 within the lens support 2. This visible mechanical folding action clearly indicates the shooting status, alleviating public anxiety. It also allows these smart glasses to be legally used in some sensitive locations, such as hospitals or conference rooms, expanding their market application scope.

[0037] When the lens support 2 is flipped to a designated position, it can automatically cut off the power supply to the image acquisition module. This automatic cutting off of the power supply to the battery module for the smart glasses or the power supply to the optical waveguide lens 3 after the lens support 2 is flipped ensures that it cannot be bypassed by software.

[0038] Please refer to Figure 4In the second embodiment of this utility model, which differs from the first embodiment, two third elastic bandages 15 are provided above the first elastic bandage 12 and the second elastic bandage 14, and each of the third elastic bandages 15 is attached to the temporal bone.

[0039] Adding a third elastic bandage 15 ensures better stability of the smart glasses while minimizing the impact on hairstyle, allowing them to rotate with head movement.

[0040] Please refer to Figure 5 and Figure 6 In the third embodiment of this utility model, the supporting element 1 is a helmet, the bottom of the supporting element 1 is provided with a fourth elastic bandage 10, and the top of the supporting element 1 is provided with a first supporting shell 111 for installing electronic components.

[0041] The top sidewall of the bearing element 1 is provided with a bearing groove 4, and a hinged support column 41 is detachably installed inside the bearing groove 4. The lens support 2 is in the shape of an inverted U. A plurality of first hinged connecting plates 22 are provided on one side of the lens support 2. The plurality of first hinged connecting plates 22 are connected to the end of the hinged support column 41 by a second hinged pin 23. Camera support frames 24 are provided on both sides of the lens support 2, and the miniature camera 5 and the optical waveguide lens 3 are respectively installed inside the camera support frame 24 and at the end of the camera support frame 24.

[0042] During the wearing process, the user places their head inside the support element 1 and the fourth elastic bandage 10 is tightly fitted to the user's chin. Similarly, this structure also relieves the pressure on the bridge of the nose during the wearing of smart glasses and utilizes the head to support all the weight of the smart glasses.

[0043] The first carrier housing 111 is used to house the aforementioned battery module, processor board and other components, while audio receiving and amplifying components such as microphones can be integrated and set in the carrier element 1 near the user's ear. The first carrier housing 111 establishes communication with the miniature camera 5 and the optical waveguide lens 3 in the lens support 2 through wires.

[0044] In the third embodiment, when the lens support 2 is flipped, the first hinge connecting plate 22 on one side of the lens support 2 rotates relative to the hinge support column 41, and the second hinge pin 23 can use the buckle structure in the first embodiment to complete the limiting support for the first hinge connecting plate 22. The camera support frame 24, the miniature camera 5, and the optical waveguide lens 3 on both sides of the lens support 2 are all flipped together.

[0045] Similarly, this structure also enables the angle adjustment of the miniature camera 5 inside the lens support 2. This visible mechanical folding action clearly indicates the shooting status, alleviating the anxiety of others.

[0046] Please refer to Figure 7 , Figure 8 and Figure 9 In the fourth embodiment of this utility model, the supporting element 1 may be a supporting frame 16 and supporting temples 17 hinged to both sides of the supporting frame 16. Each supporting temple 17 has a fifth elastic bandage 18 at its end, and a bidirectional buckle 6 is provided between adjacent fifth elastic bandages 18. At least one supporting temple 17 has a second supporting housing 19 for storing electronic components on its side wall. The lens support 2 can be flipped relative to the supporting frame 16.

[0047] During the wearing process, the user places the support frame 16 and support temple 17 on the temporal bone of the head and then locks them in place using the two-way buckle 6. During the fastening process, the fifth elastic bandage 18 will deform to adapt to different head shapes.

[0048] The second support housing 19 is used to house the aforementioned battery module, processor board, microphone and other audio receiving and amplifying components. The second support housing 19 also establishes communication with the miniature camera 5 and the optical waveguide lens 3 inside the lens support 2 through wires.

[0049] The lens support 2 is provided with a miniature camera 5 on its top, and the top center of the support frame 16 is provided with a hinge support block 161. The side wall of the lens support 2 is provided with a plurality of second hinge connecting plates 25. The plurality of second hinge connecting plates 25 are connected to the hinge support block 161 by a third hinge pin 26. The optical waveguide lens 3 is installed at the bottom of the lens support 2.

[0050] In the fourth embodiment, when the waveguide lens 3 is flipped, the lens support 2 can be flipped relative to the support frame 16. The second hinge connecting plate 25 on one side of the lens support 2 rotates relative to the hinge support block 161. The third hinge pin 26 can use the buckle structure in the first embodiment to complete the limiting support for the second hinge connecting plate 25. The miniature camera 5 on the top of the lens support 2 and the optical waveguide lens 3 are both flipped together.

[0051] Similarly, the structure of the fourth embodiment also enables the adjustment of the angle of the miniature camera 5 inside the lens support 2. This shooting status is clearly indicated by the visible mechanical folding action, alleviating public privacy concerns.

[0052] Working principle and usage of this utility model:

[0053] In the first embodiment: the first elastic bandage 12 and the second elastic bandage 14 are tightly attached to the occipital bone and the frontal bone respectively, so that the bridge of the head is no longer under pressure, but the head is used to support the lens support 2 and the optical waveguide lens 3.

[0054] In the second embodiment: the first elastic bandage 12 and the second elastic bandage 14 are tightly attached to the occipital bone and the frontal bone respectively, and the third elastic bandage 15 can ensure that the entire smart glasses have better fixation while minimizing the impact on the hairstyle, and can rotate with the rotation of the head.

[0055] In the third embodiment: the head is placed inside the support element 1, and the fourth elastic bandage 10 is tightly attached to the user's chin. Similarly, this structure also relieves the pressure on the bridge of the nose during the wearing of smart glasses, and also uses the head to support all the weight of the smart glasses.

[0056] In the fourth embodiment: the support frame 16 and the support temple 17 are threaded onto the temporal bone of the head and then locked using the two-way buckle 6. During the locking process, the fifth elastic bandage 18 will deform to adapt to different head shapes.
