[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention 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 the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of this invention, 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. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly 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 invention based on the specific circumstances.

[0035] Figure 1 shows a schematic diagram of the structure of a transition circuit assembly provided in some embodiments of this disclosure. This transition circuit assembly can be disposed on a small electronic device for circuit switching between two electronic components on the electronic device. As an example, the transition circuit assembly can be disposed on a camera module for circuit connection between the camera module and glasses, etc.

[0036] In some optional embodiments, taking a camera module as an example, as shown in Figures 2 and 3, a camera module typically includes a housing 7, a camera 3, and a first element 2, where the first element 2 can be a first connector. The housing 7 has a cavity, the camera 3 can be disposed within the housing 7, the first element 2 can be disposed on the surface of the housing 7, and a transfer circuit assembly can be disposed within the cavity of the housing 7. This transfer circuit assembly can electrically connect the first element 2 and the camera 3 respectively, thereby achieving a communication connection between the camera 3 and the first element 2. The first element 2 can send control signals to the camera 3 through the transfer circuit assembly, and the camera 3 can transmit the acquired image data to the first element 2 through the transfer circuit assembly. Figure 2 shows a schematic diagram of the structure of a camera module provided in some embodiments of this disclosure. Figure 3 shows an exploded view of a camera module provided in some embodiments of this disclosure.

[0037] In some optional embodiments of this disclosure, the adapter circuit assembly may include a first rigid circuit board 1 and a second rigid circuit board 4. The first rigid circuit board 1 can be used to electrically connect a first element 2, which can be used to send control signals to the camera 3. The shape of the second rigid circuit board 4 matches the camera 3 for mounting on the camera 3. The first rigid circuit board 1 and the second rigid circuit board 4 can be electrically connected. The second rigid circuit board 4 is adaptively designed according to the shape characteristics of the camera 3, enabling it to match the camera 3. For example, the second rigid circuit board 4 can be positioned and engaged with the camera 3 without interfering with it, thus improving the assembly structure stability of the second rigid circuit board 4.

[0038] In some optional embodiments, as shown in FIG1, the conversion circuit board assembly may further include a first flexible circuit board 5. The first flexible circuit board 5 may be connected between the second rigid circuit board 4 and the first rigid circuit board 1 so that the first element 2 can send control signals to the camera 3. The first flexible circuit board 5 is deformable, not only to realize the connection between the first rigid circuit board 1 and the second rigid circuit board 4, but also to set the connected first rigid circuit board 1 and the second rigid circuit board 4 in a relative position with an included angle. As an example, the orientation of the camera 3 is different from the orientation of the first element 2. In order to accommodate the orientation of both, the first rigid circuit board 1 and the second rigid circuit board 4 may be connected to the first element 2 and the camera 3 after being set at an included angle. At this time, the first flexible circuit board 5 used to connect the first rigid circuit board 1 and the second rigid circuit board 4 may be adaptively bent so that the two rigid circuit boards are set at a predetermined included angle.

[0039] It is understood that the first element 2 can generate a control signal first and then send it, or it can receive a control signal from other elements such as an MCU (e.g., a controller) and then send the received control signal. In some optional embodiments, the first element 2 can be a first connector for electrical connection with a second connector 400 on the electronic device. The first connector can be disposed on the outer surface of the housing 7, and can be electrically connected to the camera 3 via a conversion circuit board assembly, thereby enabling the camera 3 to acquire electrical signals or control signals through the first connector.

[0040] In some optional embodiments, the adapter circuit assembly may include a first rigid circuit board 1, a second rigid circuit board 4, and a first flexible circuit board 5 electrically connected between the first rigid circuit board 1 and the second rigid circuit board 4; the first flexible circuit board 5 has three included angles formed by bending, so that the first rigid circuit board 1 and the second rigid circuit board 4 electrically connected to both ends of the first flexible circuit board 5 can form a predetermined included angle. The first rigid circuit board 1 is used to electrically connect a first element 2; the second rigid circuit board 4 is used to electrically connect a camera 3, and the second rigid circuit board 4 can mount the camera 3.

[0041] In some optional embodiments, the adapter circuit assembly includes a first rigid circuit board 1, a first flexible circuit board 5, and a second rigid circuit board 4 arranged sequentially along the thickness direction of the first rigid circuit board 1; the two ends of the first flexible circuit board 5 are electrically connected to the first rigid circuit board 1 and the second rigid circuit board 4 respectively; the first flexible circuit board 5, the first rigid circuit board 1, and the second rigid circuit board 2 are arranged sequentially along the thickness direction of the second rigid circuit board 4; the thickness direction of the second rigid circuit board 4 forms an angle with the thickness direction of the first rigid circuit board 1.

[0042] In some alternative implementations, as shown in FIG1, the second rigid circuit board 4 may be perpendicular to the first rigid circuit board 1. The projection of the second rigid circuit board 4 onto the surface of the first rigid circuit board 1 falls on the surface of the first rigid circuit board 1. Alternatively, it can be described that the second rigid circuit board 4 is located on one side of the first rigid circuit board 1 along its thickness direction. It should be noted that the thickness direction of the first rigid circuit board 1 may be the direction indicated by arrow d in FIG1, as shown in FIG1.

[0043] Optionally, the camera module 100 typically includes an electrical connection plate 33, a lens barrel 32, and a base 31. The lens barrel 32 can be vertically connected to one side of the base 31, i.e., the lens barrel 32 is located on one side of the base 31. Alternatively, it can be understood that the center line of the lens barrel 32 is perpendicular to the base 31. Here, the electrical connection plate 33 can be used to connect the camera module 100 to an external circuit. The electrical connection plate 33 can be located above the base 31 and at a certain distance from the lens barrel 32 in the direction perpendicular to the base 31, as shown in Figure 1. The center line of the lens barrel 32 is parallel to the upper surface of the electrical connection plate 33. Optionally, the above-mentioned adapter circuit assembly can transfer the camera module 100 to the first element 2, etc. When the first rigid circuit board 1 and the electrical connection plate 33 are connected, the second rigid circuit board 4 is located on one side of the lens barrel 32, which facilitates the second rigid circuit board 4 and the lens barrel to be fixed together. The second rigid circuit board 4 is located on one side of the first rigid circuit board 1 along its thickness direction. When the electrical connection plate 33 is connected to the first rigid circuit board 1, the second rigid circuit board 4 can be fixed to the lens barrel 32 of the camera 3 located below the front side of the electrical connection plate 33. The arrangement of the first rigid circuit board 1 and the second rigid circuit board 2 makes the arrangement of the adapter circuit assembly and the components of the camera module 100 more compact, thereby making full use of the internal space of the housing 7 of the camera module 100 and reducing the size of the camera. The extension direction of the lens barrel 32 can be parallel to the electrical connection plate 33, and the electrical connection plate 33 can be parallel to the first component 2, so that the first component 2, the first rigid circuit board 1, and the electrical connection plate 33 can be arranged and connected sequentially along the thickness direction. The second rigid circuit board 4 is perpendicular to the first rigid circuit board 1, which facilitates the limiting fit between the second rigid circuit board 4 and the lens barrel 32 of the camera 3. The second rigid circuit board 4 can also be approximately parallel to the base 31 of the camera 3, which facilitates the assembly and connection with the base 31 of the camera module 100. In this method, while satisfying the connection relationship, the first component 2, the first rigid circuit board 1, and the electrical connection board 33 are compactly arranged, and the three are also compactly arranged with the lens barrel, the second rigid circuit board, etc., thereby further reducing the size of the camera module.

[0044] In some optional embodiments, as shown in Figures 1 and 3, the second rigid circuit board 4 has a notch 41 through which the camera 3 passes. The lens barrel 32 of the camera 3 can pass through the notch 41, or in other words, the second rigid circuit board 4 can extend circumferentially along the camera 3. The second rigid circuit board 4 is adaptively designed according to the structural characteristics of the camera 3, so that the second rigid circuit board 4 extends to a sufficient length or area for setting electronic components, without interfering with the lens barrel 32. The second rigid circuit board 4 is roughly "C"-shaped, occupies little space, and its inner side can accommodate the lens barrel 32. The cooperation structure between the adapter circuit assembly and the camera 3 is relatively compact, occupies little space, and has a reasonable layout structure.

[0045] In some optional embodiments, as shown in Figures 1 and 3, the second rigid circuit board 4 is provided with at least one connection hole 42 for connection and fixation. The second rigid circuit board 4 can be connected to the base 31 of the camera 3 or the housing 7 of the camera 3 through the connection hole 42. As an example, a fastener can pass through the connection hole 42 and be connected to the base 31 of the camera 3 or the housing 7 of the camera 3, while the other end of the fastener can be confined to the second rigid circuit board 4. The fastener can be a screw, which includes a shank and a nut. The shank passes through the connection hole and is threaded into a corresponding threaded hole on the base 31 or the housing 7, while the nut is confined to the second rigid circuit board 4.

[0046] In some optional embodiments, as shown in FIG1, an indicator light 43 may be provided on the second rigid circuit board 4. When the indicator light 43 is lit, it can indicate that the camera module 100 is in a certain state. For example, when the camera module 100 is in shooting mode, the indicator light 43 can be lit to notify others that the camera 3 is taking pictures. Multiple indicator lights 43 may be provided on the second rigid circuit board 4, and each indicator light 43 is arranged sequentially along the extension direction of the second rigid circuit board 4.

[0047] In some optional embodiments, as shown in FIG1, the first flexible circuit board 5 can be connected to the middle position of the second rigid circuit board 4 along the extension direction, and a plurality of indicator lights 43 can be respectively provided on the second rigid circuit board 4 on both sides of the first flexible circuit board 5.

[0048] In some optional embodiments, as shown in FIG1, the first rigid circuit board 1 may include an upper plate 11 and a lower plate 12, the upper plate 11 and the lower plate 12 are arranged in parallel, and there is a receiving space between the upper plate 11 and the lower plate 12 for accommodating electronic components. The upper plate 11 is used to connect the first component 2, the lower plate 12 is used to connect the first flexible circuit board 5, and the upper plate 11 and the lower plate 12 are electrically connected through a second flexible circuit board 6.

[0049] The first rigid circuit board 1, by adopting a double-layer board structure, can be easily connected to the first component 2 and the electrical connection board 33 respectively, avoiding the problem that the large overall area of ​​the first rigid circuit board 1 would result in a large camera module 100 volume when it is not separated. In addition, after the upper board 11 and the lower board 12 are separated, there is a gap between them, which can accommodate electronic components, further making full use of space.

[0050] Referring to Figures 1 to 3, the camera module 100 may include: a housing 7, a camera 3, a first element 2, and the aforementioned adapter circuit assembly. The housing 7 may have a cavity, the camera 3 may be disposed within the cavity of the housing 7, and the first element 2 may be disposed on the surface of the housing 7 for easy electrical connection to an external structure. The adapter circuit assembly may be disposed within the cavity, and the first rigid circuit board 1 of the adapter circuit assembly may be electrically connected to the first element 2, while the second rigid circuit board 4 is mounted on the camera 3. The camera module 100 may be detachably mounted on electronic devices such as glasses, and the camera module 100 may include the camera 3 for image acquisition.

[0051] The camera module 100 may include a housing 7 and a camera 3 disposed on the housing 7. In some scenarios, the camera module 100 can be inserted into a slot 2061 of compatible glasses, allowing the glasses to communicate with the camera module 100 and control the glasses to perform functions such as image acquisition, gesture recognition, and object recognition through the camera module. When the camera 3 is removed, the AR or VR experience of the glasses is not affected.

[0052] In some optional embodiments, the camera 3 may include an electrical connection plate 33, which may be parallel to the center line of the camera 3. The electrical connection plate 33 is located on one side of the second rigid circuit board 4 along its thickness direction, and the electrical connection plate 33 may be disposed opposite to the first rigid circuit board 1. The distance between the electrical connection plate 33 and the first rigid circuit board 1 is less than a preset distance, thereby allowing the electrical connection plate 33 to be disposed close to the first rigid circuit board 1.

[0053] The electrical connection plate 33 and the first rigid circuit board 1 are arranged sequentially along the thickness direction. The electrical connection plate 33 can also have a small gap with the first rigid circuit board 1, and the two are electrically connected. As an example, the gap between the electrical connection plate 33 and the first rigid circuit board 1 can also be zero, that is, the electrical connection plate 33 can be directly attached to the first rigid circuit board 1, and the electrical connection plate 33 and the first rigid circuit board 1 are electrically connected. Through the relative positioning of the electrical connection plate 33, the first rigid circuit board 1, and the second rigid circuit board 4 of the camera 3, space is fully utilized, making the overall structure of the camera module 100 compact and the layout reasonable.

[0054] In some optional embodiments, the camera 3 has a base 31 and a lens barrel 32, with the lens barrel 32 vertically connected to the base 31 and passing through the notch 41 of the second rigid circuit board 4. Alternatively, the second rigid circuit board 4 can extend circumferentially along the camera lens barrel 32 close to the base 31. The second rigid circuit board 4 is adaptively designed according to the structural characteristics of the camera 3, ensuring that the second rigid circuit board 4 extends to a sufficient length or area without interfering with the lens barrel 32. The second rigid circuit board 4 is roughly "C"-shaped, occupying little space, and its inner side allows the lens barrel 32 to pass through. The mating structure of the adapter circuit assembly and the camera 3 is relatively compact, occupying little space.

[0055] In some alternative embodiments, as shown in FIG3, the camera module 100 may further include foam 8. Foam 8 may be located within the cavity of housing 7, and foam 8 is compressed and disposed between base 31 and inner wall of housing 7, so that camera 3 is stably placed within housing 7 and is not easily shaken.

[0056] In some optional embodiments, referring to Figure 3, the camera module 100 may further include a light guide post 9. The housing 7 has a lamp hole 712 communicating with the cavity. The light guide post 9 extends to the lamp hole 712, and the projection of the light guide post 9 onto the second rigid circuit board 4 covers the corresponding indicator light 43 on the second rigid circuit board 4. When the indicator light 43 is lit, the light guide post 9 can conduct light to form a uniform bright area.

[0057] Optionally, the housing 7 has a camera hole 711 communicating with the cavity, and a lamp hole 712 is located around the camera hole 711. The lens barrel 32 of the camera 3 passes through the camera hole 711. The camera module 100 may also include a sealing ring 1002, which can be sleeved on the lens barrel 32 and located between the camera hole 711 and the lens barrel 32, thereby sealing the gap between the lens barrel 32 and the camera hole 711 and preventing water and dust impurities from entering.

[0058] In some optional embodiments, as shown in Figures 2 and 3, the housing 7 may have a camera housing portion 71 and a connector housing portion 72. The camera housing portion 71 is connected to one end of the connector housing portion 72. The lens barrel 32 of the camera 3 is disposed in the camera housing portion 71, and the first element 2 is disposed on the side of the connector housing portion 72 opposite to the camera housing portion 71. The aforementioned camera housing portion 71 and connector housing portion 72 may be arranged sequentially along the height direction of the eyeglass frame 200. When the connector housing portion 72 is inserted into the eyeglass frame 200, the camera housing portion 7 is located outside the eyeglass frame 200, and the eyeglass frame 200 will not block the camera housing portion 7, allowing external light to smoothly enter the lens barrel 32 of the camera 3.

[0059] Optionally, the camera housing 71 and the insertion housing 72 of the camera module 100 can be a single piece, and can be a single piece injection molded from plastic. Along the centerline of the lens barrel, the housing 7 can include two sequentially arranged half-housings (or, a front housing and a rear cover), each half-housing being a single piece. A portion of the camera housing 71 is located in one half-housing, and the other portion is located in the other half-housing. A portion of the insertion housing 72 is located in one half-housing, and the other portion is located in the other half-housing. The two half-housings interlock to form a complete housing 7.

[0060] Referring to Figures 1 to 3, the camera housing 71 has a camera cavity and a camera hole 711 communicating with the camera cavity. The lens barrel 32 of the camera 3 extends toward the camera hole 711. The camera module 100 also includes a camera lens 10, which can be connected to the camera housing 71 and cover the camera hole 711 to protect the internal camera 3. The camera lens 10 can be adhered to the camera housing 71 using adhesive 1001. External light passes through the camera lens 10 and enters the camera 3, enabling the camera 3 to capture images of the external environment.

[0061] In some optional embodiments, as shown in Figures 2 and 11, a mating portion 721 is provided on the plug-in housing 72. The mating portion 721 is used to engage with the slot 2061 when the plug-in housing 72 is inserted, so that the plug-in housing 72 will not easily detach from the slot 2061. A snap-fit ​​portion 207 can be provided on the inner wall of the slot 2061. The snap-fit ​​portion 207 can engage with the mating portion 721, allowing the plug-in housing 72 to be stably inserted into the slot 2061 without easily detaching, thus improving the stability of the assembly structure. When it is necessary to disassemble the plug-in housing 72, sufficient force needs to be applied to the plug-in housing 72 to allow it to disengage from the slot 2061. The plug-in housing 72 can be easily plugged into and unplugged from the slot 2061. The mating portion 721 and the snap-fit ​​portion 207 can have various structures to achieve the snap-fit ​​engagement between the plug-in housing and the slot.

[0062] In some optional embodiments, the housing 7 of the camera module 100 may include two oppositely arranged mating portions 721. Optionally, the two mating portions 721 are located on opposite sides of the insertion housing portion 72, and can respectively engage with opposite sides of the inner wall of the slot 2061, improving the assembly structural stability of the camera module 100. Furthermore, the symmetrical arrangement of the two mating portions 721 ensures that the camera module 100 is subjected to symmetrical forces on both sides, allowing the camera module 100 to maintain a straight posture and prevent tilting after insertion into the slot 2061.

[0063] Typically, based on the solution provided in this disclosure, the two states of smart glasses with and without a camera module can correspond to smart glasses with and without a camera module, respectively. Users can choose whether to install the camera module 100 according to their needs to experience the two different products.

[0064] Optionally, the camera hole 711, each mating part 721, and the first connector can be located on different sides of the housing 7, thereby making full use of the structure of the housing 7 and reducing its volume. The two mating parts 721 are located on opposite surfaces of the insertion housing part 72, and the first connector is located on the top surface of the insertion housing part 72. The camera module 100 has a compact overall structure and a reasonable layout.

[0065] In some alternative implementations, as shown in Figure 2, the surface of the housing 7 may have a recess, in which the first connector is embedded. The recess allows the first connector to sink into the recess, thus protecting it. Simultaneously, the recess defines the installation position of the first connector, facilitating rapid assembly and improving assembly efficiency.

[0066] Figure 4 shows a perspective view of the eyeglasses provided in some embodiments of the present disclosure; Figure 5 shows an exploded view of the eyeglasses provided in some embodiments of the present disclosure; and Figure 6 shows a cross-sectional view of the eyeglasses provided in some embodiments of the present disclosure. The eyeglasses may include a frame 200, on which a slot 2061 is provided, extending along the height direction of the frame 200. The slot 2061 is used for detachably connecting the aforementioned camera module 100. When the camera module 100 is inserted into the slot 2061, the camera module 100 can be connected to the circuitry of the eyeglasses.

[0067] The height direction of the aforementioned frame 200 can be understood as the direction indicated by arrow H in Figure 4. The aforementioned slot 2061 is used for detachably connecting the aforementioned camera module 100. The camera module 100 can be inserted into the slot 2061 along the height direction of the frame 200, and the camera module 100 can also be pulled out of the slot 2061 along the height direction of the frame 200. With the camera module 100 inserted into the slot 2061, the mating part 721 and the locking part 207 within the slot 2061 engage, allowing the camera module 100 to be electrically connected to the internal circuitry of the glasses.

[0068] In some optional embodiments, the eyeglasses provided in this disclosure can be eyeglasses with temples 300 connected to the frame 200. The eyeglasses provided in this disclosure can also be headband-style eyeglasses without temples 300. The embodiments of this disclosure do not limit the type of eyeglasses.

[0069] In some alternative implementations, as shown in FIG6, the first element 2 in the camera module 100 may be a first connector. Accordingly, the glasses may also include a second connector 400 disposed within a slot 2061. With the camera module 100 inserted into the slot 2061, the first connector and the second connector 400 are electrically connected.

[0070] When the camera module 100 is inserted into the slot 2061 on the frame 200, the first connector and the second connector 400 can be electrically connected, realizing the effective assembly of the camera module 100. The camera module 100 can be used with the glasses, expanding the functionality of the glasses and enabling them to perform functions such as image acquisition, gesture recognition, and object recognition. When the camera module 100 and the smart glasses are snapped together, the camera module 100 can be stably assembled in the slot 2061 without easily detaching from the slot 2061.

[0071] Figure 7 illustrates the mating structure of the camera module and the second connector 400 provided in some embodiments of this disclosure, and Figure 8 shows a schematic diagram of the structure of the second connector 400 in glasses provided in some embodiments of this disclosure. The first element 2, i.e., the first connector, can be a micro-pin connector. The first connector may include a fixing bracket and micro-pins, with the micro-pins disposed on the fixing bracket. The second connector 400 can be a structure that mates with the micro-pin connector. As an example, the first connector and the second connector 400 can be either a BTB connector (or board-to-board connector) or a pogo pin connector (or spring pin connector).

[0072] In some optional embodiments, as shown in Figures 5 to 7, a circuit board may be provided on the frame 200 or temple 300 of the eyeglasses. Taking the circuit board being located on the frame 200 as an example, the circuit board can be fixed to one side of the frame 200, and the circuit board can be connected to the second connector 400 in various ways. As an example, the circuit board can be electrically connected to the second connector 400 via an external adapter FPC 700. Optionally, a main board 500 with a controller can be provided inside the frame 200 of the eyeglasses, and the second connector 400 can be connected to the main board 500 via an external adapter FPC 700.

[0073] In some optional embodiments, as shown in FIG8, the second connector 400 may include a sheet body and a plurality of elastic contacts disposed on the sheet body. When the plug shell 72 is inserted into the slot 2061, each micro pin of the first connector makes elastic contact with the elastic contacts on the sheet body, thereby enabling the camera module 100 to be connected to the glasses circuit through the second connector 400, and the glasses can use the camera module 100 normally.

[0074] In some alternative embodiments, the mating part 721 and the snap-fit ​​part 207 can employ various different snap-fit ​​structures. As an example, the mating part 721 may include a claw disposed on the insertion housing part 72, and the snap-fit ​​part 207 may include a slot disposed on the inner wall of the slot 2061. When the insertion housing part 72 of the camera module 100 is inserted into the slot 2061, the claw engages with the slot.

[0075] In some optional embodiments, as shown in FIG4, the eyeglass frame 200 may include two frame bodies 201 and a connecting frame 202. The two frame bodies 201 are connected by the connecting frame 202. A slot 2061 is provided in the connecting frame 202, and the insertion shell 72 of the camera module 100 is inserted into the slot 2061.

[0076] Optionally, the frame 201 can be a lens rim for mounting lenses. The connecting bracket 202 is located in the middle of the frame 200 along its width, and the slot 2061 is located on the connecting bracket 202 to facilitate the centering of the entire eyeglass. The larger volume of the connecting bracket 202 makes it easier to set up the slot 2061 to accommodate the camera module 100. The width direction can be understood as the direction in which the two frames 201 are arranged, as shown by arrow W in Figure 4. The connecting bracket 202 and the frame 201 can be an integral structure, or the connecting component and the frame 201 can be separate parts. The connecting bracket 202 and the frame 201 can be connected by snap-fit, fastener 600, adhesive, or welding; there is no single limitation here.

[0077] In some optional embodiments, as shown in FIG4, a nose clearance area 203 is formed between the connecting frame 202 and the two frames 201, and the camera housing portion 71 of the camera module 100 extends along the height direction of the frame 200 to the nose clearance area 203. The slot 2061 may have an insertion port provided on the connecting frame 202, located on one side of the nose clearance area 203. After the user wears the glasses, the insertion port faces the user's nose. The camera 3 is disposed inside the camera housing portion 71 of the camera module 100, the camera housing portion 71 is exposed to the nose clearance area 203, and the camera 3 is exposed outside the frame 200 of the glasses. The external light shell directly enters the camera hole 711 on the camera housing portion 71, without the need to open a clearance hole on the frame 200 to avoid the camera 3, so that the structural strength of the frame 200 is maintained well.

[0078] In some optional embodiments, as shown in FIG5, the frame 200 may include a front shell 204, a back shell 205, and a crossbeam 206. The front shell 204 and the back shell 205 are fastened together, forming a cavity between them. The crossbeam 206 is located in the cavity and is connected to at least one of the front shell 204 and the back shell 205 to secure the crossbeam 206 within the cavity. A slot 2061 is formed between any one or any two adjacent of the front shell 204, the back shell 205, and the crossbeam 206. The crossbeam 206 can secure structures in the smart glasses, such as electrical components and optomechanical components, wherein the electrical components can assist the second connector 400 in providing electrical signals to the camera module 100.

[0079] Optionally, the aforementioned slot 2061 can be disposed on the crossbeam 206. Compared to the eyeglass front shell 204 and eyeglass back shell 205, which are typically thin-shell structures, the crossbeam 206 has high structural strength and a large thickness, therefore the slot 2061 can be disposed on the crossbeam 206.

[0080] Figure 9 shows a bottom view of a partial structure of the eyeglasses. Figure 10 shows a bottom view of the eyeglass frame. In some optional embodiments, the rear shell 205 of the eyeglasses may be provided with a clearance opening 2051 corresponding to the slot 2061. This allows the insertion port of the slot 2061 to be exposed at the lower edge of the frame 200, facilitating the assembly and disassembly of the camera module 100. It is understood that when there is interference or obstruction between the slot 2061 on the front shell 204 and the crossbeam 206, a clearance opening 2051 may also be provided on the front shell 204. The clearance openings 2051 of the front shell 204 and the rear shell 205 of the eyeglasses are connected and jointly avoid the slot 2061.

[0081] Figure 11 shows a partial structural schematic diagram of the crossbeam in the eyeglasses provided in an embodiment of the present disclosure; Figure 12 shows another partial structural schematic diagram of the crossbeam in the eyeglasses provided in an embodiment of the present disclosure; Figure 13 shows a state diagram of the slot on which the camera module provided in an embodiment of the present disclosure is installed. In some optional embodiments, the eyeglasses may include an elastic member 2071 and a ball 2072. The two ends of the elastic member 2071 can respectively abut against the crossbeam 206 and the ball 2072. When the insertion shell portion 72 of the camera module 100 is inserted into the slot 2061, the ball 2072 is partially embedded in the mating portion 721 on the insertion shell portion 72.

[0082] Compared to the snap-fit ​​structure of claws and slots, the snap-fit ​​structure between the ball 2072 and the recessed mating part 721 provides a more stable engagement. The mating part 721 may include a groove on the surface of the insertion shell 72. The inner surface of the groove is a smooth arc surface, and part of its surface matches the surface of the ball 2072. When the ball 2072 is embedded in the groove, under the action of the elastic element 2071, the ball 2072 automatically adjusts its position and moves to the center of the groove, thus achieving automatic centering. Both the ball 2072 and the groove have smooth surfaces, making the insertion operation of the insertion shell 72 smoother, providing a better feel, and extending its service life.

[0083] In some alternative embodiments, the eyeglasses include a mounting frame 2073, on which are provided inserts 20731. The inserts 20731 are provided with the elastic element 2071 and balls 2072. When the mounting frame 2073 is mounted on the crossbeam 206, the two inserts 20731 are located on either side of the slot 2061, and the balls 2072 on the two inserts 20731 partially extend into the slot 2061. During the insertion of the insertion shell 72 into the slot 2061, the insertion shell 72 pushes the two balls 2072 away from the outside of the slot 2061, at which point the elastic element 2071 is further compressed. When the insertion shell 72 is fully inserted, the elastic element 2071 elastically releases, pushing the balls 2072 into the grooves on the surface of the insertion shell 72, thereby achieving a snap-fit ​​fixation of the insertion shell 72.

[0084] Optionally, the mounting bracket 2073 can be fixed to the crossbeam 206 by fasteners 600. For example, the mounting bracket 2073 has connection holes 42 at each of its four corners, and the shanks of the four screws pass through the corresponding connection holes 42 and are threaded into the corresponding threaded grooves on the crossbeam 206, while the heads of the screws are confined to the mounting bracket 2073.

[0085] Optionally, the crossbeam 206 is provided with two recesses 2062, which are respectively located on both sides of the slot 2061 and are connected to the slot 2061, providing space to accommodate the insert 20731, and positioning the insert 20731 on both sides of the slot 2061. A mounting bracket 2073 is connected to the crossbeam 206 and covers the slot 2061. The insert 20731 is embedded in the recess 2062. The mounting bracket 2073 has a through hole that avoids the slot 2061, allowing the insertion shell 72 to pass through the through hole and be smoothly connected to the slot 2061.

[0086] The insert 20731 has a receiving cavity and a ball hole 207311 connecting the receiving cavity and the slot 2061. The ball 2072 can be disposed in the receiving cavity. The elastic element 2071 is at least partially located in the receiving cavity and abuts against the ball 2072, so that the ball 2072 partially extends out of the ball hole 207311 and does not completely detach from the ball hole 207311 and enter the slot 2061. The elastic element 2071 can be a spring, with its two ends abutting against one side wall of the ball 2072 and the slot 2062, respectively.

[0087] 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.
