[0032] The following combines Figures 1 to 8 to describe the wearable device provided by the embodiments of the present application.

[0033] The wearable device provided by the embodiments of the present application includes a first frame 1, a nose pad assembly 2, and a second frame 3. The nose pad assembly 2 is fixedly connected to the near-eye side of the first frame 1, and the nose pad assembly 2 is formed with a card slot 211. The card slot 211 can be, for example, a U-shaped card slot or a card slot with other suitable structures. At least one hole 2112 is provided on the first side wall 2111 of the card slot 211 facing the near-eye side. As Figure 8 shown, the second frame 3 includes at least one vision correction lens 34 and a connecting portion 31. At least one protrusion is provided on one side of the connecting portion 31 facing the near-eye side. An arc surface is formed on the side of at least one protrusion. When the connecting portion 31 is inserted into the card slot 211, at least one protrusion fits into at least one hole 2112.

[0034] The wearable device can be ear-hanging type or head-mounted type. For example, the whole can be in the shape of a helmet, glasses or other shapes. For example, the wearable device can be an AR glasses or an AR helmet, etc. It should be noted that the near-eye side refers to the side of the frame facing the human eye when the wearable device is in a worn state.

[0035] In some embodiments, the wearable device may further include one or more temple arms, and related components required to implement intelligent functions are integrated in the temple arms, such as a processing unit, a speaker, a microphone, etc. In some embodiments, the processing unit may include a general main processor and one or more special coprocessors, such as a graphics processing unit (GPU), a digital signal processor (DSP), etc. In some embodiments, at least part of the processing unit can be implemented using custom circuits, such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA, Field Programmable Gate Arrays, hereinafter also referred to as "programmable logic device").

[0036] In some embodiments, the microphone is disposed on the temple so as to be able to easily receive the wearer's oral instructions at a position where the clear voice of the wearer can be easily obtained. The microphone can also be disposed on the first spectacle frame 1 for obtaining the voice input of the wearer's conversation partner. Alternatively, the microphone (such as a contact microphone) can also be disposed on the nose pad assembly 2, for example, on the nose pad of the nose pad assembly 2 in contact with the surface skin of the wearer's nose, so as to obtain voice input according to the vibration of the wearer.

[0037] In some embodiments, a pair of speakers are disposed on one temple, and are configured to form a sound dipole effect. For example, one speaker is disposed at the top of the temple, and the other speaker is disposed at the bottom of the temple. It can be understood that the speaker disposed at the bottom of the temple is closer to the ear of the wearer, while the speaker disposed at the top of the temple is farther from the ear of the wearer. Therefore, the sound fields of the two speakers in the far field of the wearer's ear are cancelled out with each other, and there is no influence on the near field sound field. Therefore, the privacy of the voice of the wearable device is improved.

[0038] The first spectacle frame 1 can be used to mount, for example, AR lenses (such as waveguide lenses), and the second spectacle frame 3 is used to mount corrective lenses, such as myopia lenses, hyperopia lenses, etc. Specifically, the nose pad assembly 2 is fixedly connected to the near-eye side of the first spectacle frame 1. The nose pad assembly 2 can be fixed by means of magnetic attraction, or can also be fixed by means of a fixing member, such as Figure 5 shown. The nose pad assembly 2 is provided with a card slot 211, and a connecting portion 31 is provided in the middle of the second spectacle frame 3. The connecting portion 31 is inserted into the card slot 211, as Figure 1 、 Figure 2 and Figure 3 shown. The second spectacle frame 3 is located on the near-eye side of the first spectacle frame 1, enhancing the user's experience and facilitating the user to disassemble the lenses in the first spectacle frame 1 and the second spectacle frame 3. Among them, the size of the connecting portion 31 matches the card slot 211, and the connecting portion 31 can be quickly inserted into the card slot 211. The centers of the second spectacle frame 3 and the first spectacle frame 1 coincide. After the user corrects the vision, the user can immerse in the virtual world. The connecting portion 31 can also be quickly pulled out for the convenience of the user to clean.

[0039] Furthermore, in order to fix the second spectacle frame 3 and the nose pad assembly 2, at least one convex portion is provided on one side of the connecting portion 31 facing the near-eye side in the embodiment of the present application, and at least one hole is provided on the first side wall of the card slot 211 facing the near-eye side. When the connecting portion 31 is inserted into the card slot 211, at least one convex portion is embedded into the corresponding hole to limit the position of the second spectacle frame 3 and prevent the second spectacle frame 3 from moving, ensuring the wearing effect of the user.

[0040] In another embodiment, at least one protrusion is provided on a side of the connecting portion 31 away from the near-eye side, and at least one hole is provided on a side wall of the card slot 211 away from the near-eye side. When the connecting portion 31 is inserted into the card slot 211, at least one protrusion is embedded into the corresponding hole, thereby restricting the position of the second spectacle frame 3.

[0041] In the embodiment of the present application, an arc surface is provided on a side of at least one of the protrusions, so that the protrusion can be better matched with the hole, and the installation and disassembly can be quickly realized, and the operation is simple.

[0042] For the wearable device provided in the embodiment of the present application, the second spectacle frame 3 includes at least one vision correction lens 34. By inserting the connecting portion 31 into the card slot 211 of the nose pad assembly 2, the second spectacle frame 3 is installed on the near-eye side of the first spectacle frame 1 to meet the visual correction needs of the user; and at least one protrusion on the connecting portion 31 is engaged into the corresponding hole of the nose pad assembly 2, thereby restricting the position of the second spectacle frame 3 and preventing the second spectacle frame from moving or loosening during wearing. The embodiment of the present application can quickly install and disassemble the second spectacle frame, meet the visual correction needs of the user, and improve the user experience.

[0043] On the basis of the above embodiment, when at least one protrusion is engaged into at least one hole, the surface of at least one protrusion does not exceed the surface of at least one hole. Specifically, the extension length of the protrusion is less than or equal to the depth of the hole, that is, the surface of the protrusion is lower than or equal to the surface of the hole, so as to prevent the protrusion from protruding outside the nose pad assembly 2 and avoid the protrusion from hurting the skin.

[0044] In one embodiment, the opening of the card slot 211 faces upward, and the connecting portion 31 is inserted into the card slot 211 with the opening facing upward, as Figure 2 and Figure 6 shown.

[0045] In another embodiment, the opening of the card slot 211 faces downward, and the connecting portion 31 is inserted into the card slot 211 with the opening facing downward. It should be noted that when the opening of the card slot 211 faces downward, the connecting portion 31 is fixedly connected to the nose pad assembly 2 to prevent the second spectacle frame 3 from falling off due to gravity.

[0046] In the embodiment of the present application, a partial arc surface near the bottom of at least one protrusion abuts against the inner wall of at least one hole to restrict the position of the protrusion.

[0047] It can be understood that a partial arc surface of at least one convex portion abuts against the inner wall of at least one hole, indicating that the partial arc surface and the inner wall of at least one hole (the contact portion) are subject to mutual acting forces, which can be achieved, for example, by an interference fit between the partial side portion characterized by the partial arc surface and at least one hole. It should be noted that since the side portion has a larger size (such as diameter or radius) closer to the bottom of at least one convex portion, the interference fit between the partial side portion characterized by the partial arc surface closer to the bottom and at least one hole is more compact and can provide a greater acting force. For example, when the partial side portion just starts to contact the inner wall of at least one hole, the size of the partial side portion is equal to the size of the inner wall of at least one hole. The size of the partial side portion continuing to extend along the bottom exceeds the size of the inner wall of at least one hole by 0.01 mm, and the size of the partial side portion continuing to extend along the bottom exceeds the size of the inner wall of at least one hole by 0.02 mm until the size of the partial side portion close to the bottom exceeds the size of the inner wall of at least one hole by 0.03 mm. Of course, since the side portion extends towards the bottom in the form of an arc surface, the size relationship between the side portion and the inner wall of at least one hole can be non-linear, for example, in the form of a curve.

[0048] It should be noted that when the connecting portion 31 is installed into the card slot 211 of the nose pad assembly 2, the abutment of the partial arc surface of at least one convex portion against the inner wall of at least one hole can stably and reliably fix at least one convex portion in at least one hole, which enables the connecting portion 31 and the corresponding vision correction lens 34 to have a good fixing effect when in use and will not simply fall out of the card slot 211.

[0049] It can be understood that since the size of the arc surface (side portion) is configured to increase towards the bottom, this not only enables a good acting force to be provided when at least one convex portion is inserted into at least one hole and the partial arc surface abuts against the inner wall of at least one hole, ensuring the stability of the connection between the connecting portion 31 and the card slot 211. It can also provide a good removal experience when it is necessary to remove the connecting portion from the card slot.

[0050] It can be understood that the thickness of the card slot 211 is greater than the thickness of the connecting portion 31, which can ensure a certain operating margin when the connecting portion 31 and the card slot 211 are connected and removed.

[0051] In some embodiments, the arc surface of the side portion is configured as a smooth arc surface, which improves the operability of connection and removal.

[0052] In one embodiment, at least one convex portion is formed on the surface of the connecting portion 31 close to the wearer side, and at least one convex portion can be integrally formed with the connecting portion 31. In another embodiment, at least one convex portion includes a bottom portion, a side portion and a top portion, wherein the bottom portion and the surface of the connecting portion 31 are both configured as a whole, or the bottom portion is fixedly connected to the surface of the connecting portion 31, the top portion is configured as a flat surface, and the size of the top portion is smaller than that of the bottom portion, the side portion is configured to connect the top portion and the bottom portion of at least one convex portion, and the side portion is formed with an arc surface, the size of the top portion is smaller than that of the bottom portion, and the size of the side portion gradually increases from the near-eye side to the far-eye side. In at least one embodiment, both the top portion and the bottom portion of the convex portion are configured as circular surfaces.
