Description

Technical Field

[0001] The present application relates to the field of terminal devices, and in particular, to a wearing detection component, smart glasses, and a wearing detection method. Background Art

[0002] Smart wearable devices, such as smart glasses and smart watches, are intelligent devices that realize functions such as user interaction, human health monitoring, and life entertainment with the support of biosensor technology, wireless communication technology and intelligent analysis software.

[0003] Generally speaking, the health monitoring, life entertainment and other functions of smart wearable devices are realized based on the user wearing the device correctly. If the user enables the above functions of the device without wearing the device correctly, on the one hand, it may cause the device functions to not be realized normally or the device to operate incorrectly. For example, smart glasses cannot perform health monitoring of the user normally, or the health monitoring results are unreliable. On the other hand, it will also increase the power consumption of the smart wearable device and shorten the average usage time of the device.

[0004] How to improve the stability and reliability of the functions of smart glasses and enhance the energy efficiency of smart glasses are issues worth considering. Summary of the Invention

[0005] The present application provides a wearing detection component, in which a sensing device is accommodated inside the nose pad of the wearing detection component, and an internal protrusion is provided on the side of the inner wall of the nose pad facing the sensing device. When the outside of the nose pad is squeezed, the internal protrusion can approach and contact the sensing device, and the sensing device can generate an electrical signal accordingly. The electrical signal can reflect the contact state between the outer wall of the nose pad and the user's nose bridge, and can be used to determine the wearing state of electronic devices such as glasses equipped with the wearing detection component. The wearing detection component judges the wearing state through the principle of direct contact with the user, and the detection of the wearing state is more efficient and reliable.

[0006] In a first aspect, a wearing detection component is provided, comprising: a nose pad and a nose pad frame, the nose pad frame being connected to the nose pad; the nose pad comprises an abutment wall, the abutment wall is away from the nose pad frame, an internal protrusion is provided on the inner side of the abutment wall, a sensing device is housed in the nose pad, the sensing device is arranged close to the internal protrusion, and the sensing device is configured to generate an electrical signal when the internal protrusion contacts the sensing device.

[0007] In a possible implementation, the nose pad may be made of resin and / or silicone material. When the abutting wall is squeezed, it may deform or displace, or in other words, when the abutting wall is squeezed, the internal protrusion may approach until it contacts the sensing device.

[0008] In a possible implementation, the sensing device may be any one of a membrane switch, a piezoelectric switch, a pressure sensor, and the like.

[0009] In a possible implementation, the sensing device may be a plate-shaped or sheet-shaped structure. In this case, the sensing device being disposed close to the internal protrusion may also be understood as the sensing device being disposed facing the internal protrusion.

[0010] In a possible implementation, the nose support can be movably connected or fixedly connected to the nose pad. For example, the nose pad can be connected to the nose support by screw connection, adhesive connection or welding.

[0011] In some scenarios, the above-mentioned nose pad having a sensing device disposed therein may also be understood as the nose pad having a sensing device disposed therein.

[0012] In some scenarios, the inner protrusion that abuts the wall may also be referred to as an inner contact point.

[0013] In some scenarios, the electrical signal generated by the sensing device may be a current signal or a voltage signal.

[0014] In the present technical solution, an internal protrusion and a sensing device are provided inside the nose pad. When the nose pad is subjected to an external force, the sensing device can generate an electrical signal indicating that the nose pad is squeezed. The electrical signal can be used to determine the wearing status of the glasses equipped with the wearing detection component. The wearing status detection using the wearing detection component is more efficient and reliable.

[0015] In combination with the first aspect, in certain implementations of the first aspect, an external protrusion is provided on the outer side of the abutting wall, and the external protrusion corresponds to the internal protrusion.

[0016] In some scenarios, the external protrusion may also be referred to as an external contact.

[0017] In this technical solution, an external protrusion corresponding to the internal protrusion is provided on the outer side of the nose pad's abutment wall. The external protrusion can directly contact the user's nose bridge area. The internal stress generated by the compression of the external contact point can directly act on the internal protrusion, causing the internal protrusion to deform and / or displace and contact the sensing device, which can then generate an electrical signal. Implementation of this technical solution facilitates more effectively converting external forces into deformation and / or displacement of the internal protrusion, facilitating the sensing device to generate an electrical signal, and facilitating the wear detection function of the wear detection component.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the number of internal protrusions and the number of external protrusions are both multiple, the multiple internal protrusions are spaced apart, the multiple external protrusions are spaced apart, and the multiple internal protrusions correspond one-to-one to the multiple external protrusions.

[0019] In some scenarios, the spacing between multiple internal protrusions can also be understood as the multiple internal protrusions being distributed in a lattice shape. Similarly, the spacing between multiple external protrusions can also be understood as the multiple external protrusions being distributed in a lattice shape.

[0020] The multiple internal and external protrusions can be distributed in different areas of the abutment wall, allowing the multiple protrusions to reflect the contact status between different areas of the abutment wall and the user's nose bridge. In other words, the provision of multiple protrusions enables the sensing device to generate electrical signals indicating the contact status of different areas of the abutment wall. The implementation of this technical solution helps improve the accuracy and reliability of the detection results of the wear detection component. Furthermore, the provision of multiple protrusions on the outer surface of the abutment wall helps increase the contact area between the nose pad and the user's nose bridge when worn, increasing the friction between the nose pad and the nose bridge, and to some extent, preventing the nose pad from slipping.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the internal protrusion and the external protrusion are both columnar, and the internal protrusion is coaxial with the corresponding external protrusion.

[0022] Configuring both the inner and outer protrusions in a cylindrical shape increases the contact area between the outer protrusion and the user's nose bridge, and thus the contact area between the inner protrusion and the sensing device. Coaxially arranging a set of inner and outer protrusions facilitates converting forces acting on the outer protrusions into deformation and / or displacement of the inner protrusions, facilitating the wear detection component's functionality.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the distances between the end surfaces of the plurality of internal protrusions at one end close to the sensing device and the sensing device are equal.

[0024] In a possible implementation, end surfaces of the multiple internal protrusions close to one end of the sensing device may be parallel to the plane where the sensing device is located.

[0025] In this technical solution, the distance from the end face of one end of the multiple internal protrusions that contact the sensing device to the sensing device is set to be the same, which is conducive to simplifying the installation of the sensing device in the nose pad, improving the assembly efficiency of the wearing detection component, and to a certain extent, also conducive to improving the reliability and effectiveness of wearing status detection.

[0026] In combination with the first aspect, in certain implementations of the first aspect, end surfaces of the multiple external protrusions away from one end of the internal protrusion form a curved contact surface, and a middle area of the contact surface is raised.

[0027] In some scenarios, the raised middle area of the contact surface may also be understood as the height of the outer protrusions of the middle area being higher than the heights of the outer protrusions of the surrounding areas.

[0028] In a possible implementation, an end surface of the outer protrusion away from the inner protrusion may be a curved surface.

[0029] In a possible implementation, the surface shape of the contact surface formed by the end surface of the external protrusion may be the same as or similar to the shape of the outer surface of the abutting wall.

[0030] In this technical solution, the contact surface composed of the end faces of the external protrusions is set to the shape of a bulge in the middle area, which is conducive to allowing the external protrusions to fully contact the user's nose bridge, allowing more external protrusions to contact the user's nose bridge, and allowing the sensing device to generate more electrical signals, which is conducive to more accurately detecting the wearing status of the glasses equipped with the wearing detection component.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the abutting wall, the inner protrusion, and the outer protrusion are integrally formed.

[0032] In a possible implementation, the nose pads may be manufactured through an integrated molding process.

[0033] Integrally molding the abutting wall, the inner protrusion, and the outer protrusion is beneficial for simplifying the preparation process of the nose pad and improving the production efficiency of the wearing detection component.

[0034] In combination with the first aspect, in certain implementations of the first aspect, the nose pad further includes a mounting wall and a dumbbell-shaped support stem, the mounting wall is arranged opposite to the abutment wall, a through hole is provided in the mounting wall, the supporting end of the support stem is accommodated in the nose pad, and the support stem passes through the through hole.

[0035] In some scenarios, the structure including the mounting wall and the abutment wall can be called the stipule of the nose pad. The present technical solution can also be understood as: the stipule and the stem of the nose pad can be a split structure, and the stipule of the nose pad is mounted on the outside of the stem through the through hole on the mounting wall.

[0036] Setting the stipules and stems of the nose pad separately is conducive to setting different functions for different structures of the nose pad. In addition, the split stipules and stems are conducive to using different materials to prepare the stipules and stems, which is conducive to improving the reliability of the nose pad structure.

[0037] In combination with the first aspect, in certain implementations of the first aspect, the sensing device is carried on the supporting end of the nose support, and a side of the supporting end away from the sensing device abuts against the mounting wall of the nose support.

[0038] In one possible implementation, the supporting surface of the support end of the support stem that supports the sensing device may be a plane, and the shape of the surface of the support end that contacts the mounting wall may match the shape of the inner surface of the mounting wall, thereby allowing the support end and the mounting wall to fit as closely as possible.

[0039] One end of the nose pad contained in the nose pad serves as a platform for carrying the sensing device. The implementation of this technical solution is conducive to more stably installing the sensing device inside the nose pad, improving the stability of the internal structure of the nose pad, and improving the reliability of the detection function of the wearing detection component.

[0040] In combination with the first aspect, in certain implementations of the first aspect, the nose pad includes an annular nose pad seat, and the nose stem passes through the nose pad seat.

[0041] In some scenarios, the support stem passing through the nose pad seat can also be understood as the nose pad seat being arranged on the outside of the support stem.

[0042] In a possible implementation, the annular nose pad seat may be provided with a notch, and the notch may be used as an installation channel for the nose pad seat to be arranged on the outside of the nose stem during the assembly process.

[0043] The nose pads and nose pad seats can be mounted on the outside of the nose pad stem. The implementation of this technical solution is conducive to simplifying the connection relationship between the various structural elements of the wearing detection component, and is conducive to improving the assembly and production efficiency of the wearing detection component.

[0044] In combination with the first aspect, in certain implementations of the first aspect, a connecting channel is opened in the support stem, and the openings at both ends of the connecting channel are respectively located on the end surface of the supporting end and the end surface of the fixed end.

[0045] In combination with the first aspect, in certain implementations of the first aspect, the wearing detection component further includes a connecting wire, the connecting wire is electrically connected to the sensing device, and the connecting wire at least partially passes through the connecting channel.

[0046] The electrical connection line used to connect the sensing device inside the nose pad and the external circuit can be partially accommodated in the connection channel opened inside the nose pad. The implementation of this technical solution is conducive to improving the utilization efficiency of the internal space of the nose pad and simplifying the connection relationship between multiple structural elements in the nose pad.

[0047] In combination with the first aspect, in some implementations of the first aspect, the sensing device includes one or more of the following: a membrane switch, a pressure sensor, or a piezoelectric switch.

[0048] In a second aspect, smart glasses are provided, comprising a mainboard and a wearing detection component according to the first aspect and any possible implementation thereof, wherein the wearing detection component is electrically connected to the mainboard.

[0049] In a third aspect, a wearing detection method is provided, which is applied to the smart glasses in the second aspect and any possible implementation thereof, the method comprising: receiving a squeeze signal sent by a sensing device, the squeeze signal being used to indicate the contact status between the internal protrusion and the sensing device; and determining the wearing status of the smart glasses based on the squeeze signal.

[0050] In combination with the third aspect, in certain implementations of the third aspect, the number of internal protrusions is multiple, and the wearing state of the smart glasses is determined based on the squeezing signal, including: determining the number or proportion of internal protrusions in contact with the sensing device based on the strength of the squeezing signal; determining the wearing state of the smart glasses based on the number or proportion of internal protrusions in contact with the sensing device.

[0051] In combination with the third aspect, in some implementations of the third aspect, the number of internal protrusions is multiple, and the wearing state of the smart glasses is determined based on the squeezing signal, including: obtaining the number of squeezing signals within a preset time interval; determining the wearing state of the smart glasses based on the number of squeezing signals.

[0052] When there are multiple internal protrusions, the wearing state of the smart glasses is determined by the number or proportion of the internal protrusions in the squeezed state, which is conducive to more accurately determining the wearing state of the smart glasses, improving the reliability of the functions of the smart glasses, and improving the energy utilization efficiency of the smart glasses.

[0053] According to a fourth aspect, a computer program product is provided. The computer program product comprises computer program code, and when the computer program code is run on a computer, the method according to the third aspect and any possible implementation thereof is executed.

[0098] It should be understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the smart glasses 10. In other embodiments of this application, the smart glasses 10 may include more or fewer components than described above, or may combine or separate certain components, or have different component arrangements. The components described above may be implemented in hardware, software, or a combination of software and hardware.

[0099] In order to improve the accuracy of the above-mentioned smart glasses 10 in detecting whether the user is wearing the glasses or the user's wearing status, the present application provides a wearing detection component 20 of the smart glasses 10, and the wearing detection component 20 is provided with a sensing device for detecting the user's wearing status. The wearing detection component 20 is provided with a detection contact, and the smart glasses 10 can determine the wearing status of the smart glasses 10 based on the detection information fed back by the detection contact.

[0100] Combine Figure 2 and Figure 3 The wearing detection component 20 may include a nose pad 21 and a nose pad frame 22. The nose pad frame 22 may be used to support or carry the nose pad 21 and be fixedly connected to the smart glasses 10. When a user wears the smart glasses 10, the nose pad 21 may be in direct contact with the user's nose bridge, and a sensing device (not shown) may be provided inside the nose pad 21.

[0101] refer to Figure 4 In some examples, the nose pad 22 may include a connecting rod 221 and a nose pad seat 222 , wherein the nose pad seat 222 is used to achieve a fixed connection between the nose pad 21 and the nose pad 22 , and the connecting rod 221 is used to fixedly connect the nose pad 21 and the smart glasses 10 .

[0102] In some examples, the nose bracket 22 may be made of a metal material, such as pure titanium, titanium alloy, stainless steel, or aluminum-magnesium alloy.

[0103] In some examples, the nose support 22 can be made of non-metallic materials, such as plastic, carbon fiber, wood, or bamboo.

[0104] In some examples, the connecting rod 221 can be an integrated structure and can be approximately U-shaped. Two nose pads 222 can be provided at each end of the connecting rod 221, namely a first nose pad 222A and a second nose pad 222B. The first nose pad 222A can be used to securely connect to a first nose pad of a pair of nose pads 21 of the smart glasses 10, and the second nose pad 222B can be used to securely connect to a second nose pad of a pair of nose pads 21 of the smart glasses 10.

The annular nose pad seat 222 may be sleeved on the outer periphery of the fixing portion of the columnar nose pad 21, or in other words, the fixing portion of the columnar nose pad 21 may be inserted into the annular nose pad seat 222. One end of the fixing portion of the nose pad 21 extending into the nose pad seat 222 may be provided with a snap-fitting structure, which can snap the nose pad seat 222 onto the fixing portion of the nose pad 21, or in other words, the snap-fitting structure of the fixing portion of the nose pad 21 can achieve relative fixation between the nose pad 21 and the nose pad seat 222. The fixing portion of the nose pad 21 will be described in detail later and will not be expanded here.

[0106] In some examples, the nose pad seat 222 of the annular structure may be provided with a notch, and during the assembly process, the fixed portion of the columnar structure nose pad 21 may be inserted into the nose pad seat 222 from the position of the notch, thereby placing the nose pad seat 222 on the outside of the fixed portion of the nose pad 21.

[0107] For example, refer to Figure 5 The first nose pad seat 222A may be provided with a receiving cavity 225, which may be used to accommodate the fixing portion of the nose pad 21. A pair of threaded holes 224 arranged opposite to each other may be provided on the side wall of the first nose pad seat 222A.

The nose pad 21 and the first nose pad seat 222A may be fixedly connected by the threaded holes 224 on the first nose pad seat 222A, the through hole of the fixing portion of the nose pad 21, and the screw. For example, the fixing portion of the nose pad 21 may be accommodated in the first nose pad seat 222A, and a screw with an external thread may pass through the threaded hole 224 and the through hole of the fixing portion of the nose pad 21 at the same time. The inner wall of the threaded hole 224 may be provided with an internal thread, and the external thread of the screw and the internal thread of the threaded hole may engage with each other, thereby achieving a fixed connection between the first nose pad seat 222A and the nose pad 21.

[0108] It should be noted that the structure of the second nose pad seat 222B and the matching relationship between the second nose pad seat 222B and the nose pad 21 can refer to the relevant description of the first nose pad seat 222A in the above embodiment of the present application, and will not be repeated here.

[0109] A connecting portion 223 may be provided in the middle of the connecting rod 221. For example, the connecting portion 223 may be used to securely connect the connecting rod 221 to the frame 11 of the smart glasses 10. For example, the connecting portion 223 and the frame 11 may be connected by riveting, welding, gluing, or bolting.

[0110] In some examples, such as Figure 6As shown, the connecting rod 221 can be a split structure, or in other words, the connecting rod 221 can include a first sub-connecting rod 221A and a second sub-connecting rod 221B. The first sub-connecting rod 221A can be provided with a first nose pad seat 222A at the end close to the nose pad 21, and a first connecting portion 223A at the end away from the nose pad 21. The second sub-connecting rod 221B can be provided with a second nose pad seat 222B at the end close to the nose pad 21, and a second connecting portion 223B at the end away from the nose pad 21. The first nose pad seat 222A can be used to connect to the first nose pad of the pair of nose pads 21 of the smart glasses 10, and the second nose pad seat 222B can be used to connect to the second nose pad of the pair of nose pads 21 of the smart glasses 10. Both the first connecting portion 223A and the second connecting portion 223B can be used to securely connect the sub-connecting rods to the frame 11 of the smart glasses 10.

[0111] For example, continue to refer to Figure 6 The first nose pad seat 222A may be provided with a receiving cavity 225, which may be used to accommodate the fixing portion of the nose pad 21. A pair of threaded holes 224 arranged opposite to each other may be provided on the side wall of the first nose pad seat 222A. Correspondingly, a through hole may also be provided on the fixing portion of the nose pad 21. The nose pad 21 and the first nose pad seat 222A may be fixedly connected by the threaded holes 224 on the first nose pad seat 222A, the through hole of the fixing portion of the nose pad 21, and the screw. For example, the fixing portion of the nose pad 21 may be accommodated in the first nose pad seat 222A, and a screw with an external thread may pass through the threaded hole 224 and the through hole of the fixing portion of the nose pad 21 at the same time. The inner wall of the threaded hole 224 may be provided with an internal thread, and the external thread of the screw and the internal thread of the threaded hole may engage with each other, thereby achieving a fixed connection between the first nose pad seat 222A and the nose pad 21.

[0112] The first nose pad seat 222A can also be fixedly connected to the nose pad 21 in other ways. For example, the first nose pad seat 222A can be Figure 4 In the annular structure, the first nose pad seat 222A can be fixedly connected to the nose pad 21 by snapping, and this application does not impose any restrictions on this.

[0113] For example, the first connecting portion 223A and the frame 11 of the smart glasses 10 may be connected by riveting, welding, gluing, or bolting.

[0114] like Figure 6 The second nose pad seat 222B may also be provided with a receiving cavity 225, which may be used to accommodate the fixing portion of the nose pad 21. It should be noted that the structure of the second nose pad seat 222B and the matching relationship between the second nose pad seat 222B and the nose pad 21 can refer to the relevant description of the first nose pad seat 222A in the above embodiment of the present application, and will not be repeated here.

[0115] Similarly, the second nose pad seat 222B can also be fixedly connected to the nose pad 21 in other ways, and this application does not impose any restrictions on this.

[0116] For example, the second connecting portion 223B of the second sub-linking rod 221B and the frame 11 of the smart glasses 10 may also be connected by riveting, welding, gluing or bolting.

[0117] In some examples, for a split nose bracket 22, the connection position between the first connection portion 223A of the first sub-connecting rod 221A and the smart glasses 10 can be different from the connection position between the second connection portion 223B of the second sub-connecting rod 221B and the frame 11 of the smart glasses 10. For example, the first connection portion 223A can be connected to a first position of the frame 11 of the smart glasses 10, and the second connection portion 223B can be connected to a second position of the frame 11 of the smart glasses 10.

[0118] In some examples, reference Figure 2 The wearing detection component 20 may further include a cable 23, which may be used to electrically connect the sensing device in the nose pad 21 with an external circuit, and transmit the detection information obtained by the sensing device to the main board of the smart glasses 10 or a processing unit on the main board.

[0119] Combine Figure 2 and Figure 7 One end of the cable 23 can be electrically connected to the sensing device 40 in the nose pad 21, and the other end can be electrically connected to the mainboard of the smart glasses 10. Figure 2 and Figure 3 The cable 23 can be arranged along the connecting rod 221 of the nose bracket 22, or in other words, a portion of the cable 23 can be attached to the connecting rod of the nose bracket 22. The cable 23 can be electrically connected to the motherboard of the smart glasses 10 through various interfaces, such as a pin interface, a serial interface, a parallel interface, or a Universal Serial Bus (USB) interface, etc., which is not limited in this application.

[0120] refer to Figures 8 to 10 In some examples, the nose pad 21 may include a stipule 30, the first surface of the stipule 30 may be provided with a protrusion structure, and the second surface of the stipule 30 may be provided with an opening. For example, the stipule 30 may be a box body, the first surface of the box body may be provided with a protrusion structure, and the second surface of the box body may be provided with an opening. For example, in combination Figure 2The side of the stent 30 closest to the user's nose bridge is the aforementioned first surface with the raised structure, while the side away from the user's nose bridge is the second surface with the opening. In the following examples, the portion of the stent 30 including the aforementioned first surface is referred to as the abutment wall 31, and the portion of the stent 30 including the aforementioned second surface is referred to as the mounting wall 32. The abutment wall 31 can be opposite and spaced apart from the mounting wall 32. The abutment wall 31 and the mounting wall 32 can be connected by the side wall 33 of the stent 30. The abutment wall 31, the mounting wall 32, and the side wall 33 can enclose a storage space, which can be considered a cavity within the stent 30.

[0121] The above structure can also be understood as follows: the stipule 30 can include an abutment wall 31, a mounting wall 32, and a side wall 33. The outer periphery of the abutment wall 31 and the outer periphery of the mounting wall 32 are connected by the side wall 33. The inner surface of the middle region of the abutment wall 31 is spaced apart from the inner surface of the middle region of the mounting wall 32. The space formed between the abutment wall 31 and the mounting wall 32 can be considered as a cavity inside the stipule 30. The first surface of the stipule 30 can be considered as the outer surface of the abutment wall 31, and the second surface of the stipule 30 can be considered as the outer surface of the mounting wall 32.

[0122] Combine Figure 8 and Figure 9 In some examples, the number of raised structures on the first surface of the stipule 30 can be multiple, or in other words, multiple sites on the outer surface of the abutting wall 31 of the stipule 30 can extend in a direction away from the abutting wall 31 to form multiple raised structures. These raised structures on the outer surface of the abutting wall 31 can be spaced apart from each other. When the user wears the smart glasses 10, one or more of these raised structures can contact the user's nose bridge. In some scenarios, these raised structures can also be referred to as contacts or contact structures. For example, these contacts located on the first surface of the stipule 30 can be referred to as external protrusions 34, external contacts 34, or first contacts 34.

[0123] Combine Figure 9 and Figure 10 In some examples, a protrusion structure may be provided on the inner surface of the abutting wall 31 of the stipule 30. There may be multiple protrusion structures, or in other words, multiple locations on the inner surface of the abutting wall 31 may extend toward the mounting wall 32 to form multiple protrusion structures. These protrusion structures on the inner surface of the abutting wall 31 may be spaced apart from each other.

[0124] In some examples, the positions of these raised structures on the inner surface of the abutting wall 31 correspond to the positions of the raised structures on the outer surface of the stipule 30. In other words, the inner surface of the abutting wall 31 of the stipule 30 may be provided with an internal protrusion 35, an internal contact 35, or a second contact 35, and the internal contact 35 is provided corresponding to the aforementioned external contact 34.

[0125] In some scenarios, the raised structures provided on the inner and outer sides of the abutment wall 31 of the support leaf 30 can also be understood as: the support leaf 30 also includes an abutment column, one end of the abutment column (the extended end) extends outward from the outer surface of the abutment wall 31, and the other end of the abutment column (the inner convex end) protrudes inward from the inner surface of the abutment wall 31.

[0126] In some examples, reference Figure 8 , the external contacts 34 of the stipule 30 can be distributed in a lattice shape, accordingly, Figure 9 The internal contacts 35 on the inner wall of the middle support leaf 30 may also be distributed in a lattice shape. In other words, the abutment posts provided on the abutment wall 31 of the support leaf 30 may be provided in an array shape.

[0127] The external contacts 34 distributed in a lattice pattern are conducive to the smart glasses 10 capturing the squeezing signals of the external contacts 34 at different positions on the stipule 30, and the internal contacts 35 distributed in a lattice pattern are conducive to setting a sensing device 40 with multiple sensing sites in the cavity of the stipule 30, which is conducive to improving the reliability and accuracy of the smart glasses 10 in determining the user's wearing status.

[0128] In some examples, the lattice shape formed by the multiple external contacts 34 of the stipule 30 may correspond to the shape of the outer surface of the abutment wall 31. In other words, the lattice shape formed by the multiple external contacts 34 of the stipule 30 may correspond to the shape of the first surface of the stipule 30. For example, the outer surface of the abutment wall 31 may be circular, elliptical, or square, and the lattice shape formed by the multiple external contacts 34 may also be substantially the same as the corresponding circular, elliptical, or square shape. For example, Figure 8 In the embodiment, the outer surface of the abutting wall 31 is approximately elliptical, and the external contacts 34 located on the first surface are also arranged in an approximately elliptical shape.

[0129] Setting the external contacts 34 with corresponding shapes according to the shape of the surface of the stipule 30 is conducive to setting more external contacts 34 on the stipule 30, which is conducive to obtaining the compression signal between the external contacts 34 and the user's skin in a larger area, and is conducive to improving the reliability and accuracy of the smart glasses 10 in determining the user's wearing status.

[0130] In some examples, the outer surface of the abutting wall 31 may be a curved surface with a certain curvature, and the curvature of the contact surface formed by the end surfaces of the multiple external contacts 34 may match the curvature of the outer surface of the abutting wall 31. In other words, the degree of fit between the contact surface formed by the end surfaces of the multiple external contacts 34 and the user's nose bridge is substantially the same as the degree of fit between the outer surface of the abutting wall 31 and the user's nose bridge when these external contacts 34 are not provided.

[0131] For example, refer to Figure 11The extension directions of different external contacts 34 are perpendicular to the outer surface of the abutment wall 31 where the contacts are located. In this case, the vertical distances between the end faces of the external contacts 34 at different positions and the outer surface of the abutment wall 31 can be the same, or in other words, the heights of the external contacts 34 at different positions can be the same.

[0132] For example, the outer surface of the abutting wall 31 is a curved surface with a raised middle area. The height of the external contacts 34 located in the middle area on the outer surface of the abutting wall 31 is the same as the height of the external contacts 34 located in the surrounding areas, so that the contact surface formed by the end faces of different external contacts 34 can be basically consistent with the shape of the outer surface of the abutting wall 31.

[0133] For example, refer to Figure 12 , the different external contacts 34 on the outer surface of the abutting wall 31 extend in the same direction, for example, in the thickness direction of the abutting wall 31. In this case, the vertical distances between the end surfaces of the external contacts 34 at different locations and the outer surface of the abutting wall 31 can be different, or in other words, the heights of the external contacts 34 at different locations can be different.

[0134] For example, the heights of the different external contacts 34 can be determined based on the shape of the outer surface of the abutting wall 31. For example, if the outer surface of the abutting wall 31 is a convex curved surface in the middle region, the height of the external contacts 34 in the middle region can be lower than the height of the external contacts 34 in the surrounding regions. As a result, the shape of the contact surface formed by the end surfaces of the different external contacts 34 can be substantially consistent with the shape of the outer surface of the abutting wall 31.

[0135] Based on the above solution, the shape of the contact surface formed by the end surfaces of the multiple external contacts 34 is substantially consistent with the shape of the outer surface of the abutment wall 31. When the user wears the smart glasses 10, the end surfaces of the multiple external contacts 34 can fully contact and press against the skin in the user's nose bridge area, thereby enabling more compression signals to be captured by the sensing device 40, and the reliability and accuracy of the results determined by the smart glasses 10 in determining the user's wearing status are higher.

[0136] The number of external contacts 34 is related to the area of the outer surface of the abutting wall 31, the size of the external contacts 34 and the distance between different external contacts 34. In some examples, the above-mentioned external contacts 34 or the raised structures on the outer surface of the abutting wall 31 can be columnar or conical, such as cylindrical, prism-shaped, truncated cone-shaped or prism-shaped, etc., and this application does not impose any restrictions on this.

[0137] For example, the external contact point 34 can be cylindrical, and the diameter D1 of the cylinder can satisfy 1.0 mm ≤ D1 ≤ 5.0 mm. For example, D1 can be 3.0 mm. In this case, the number n1 of the external contact points 34 on the outer surface of the abutting wall 31 of the first or second nose pad in the aforementioned nose pad 21 can satisfy 6 ≤ n1 ≤ 80. For example, n1 can be 12, 24, 50, or 75.

[0138] In some examples, the plurality of internal contacts 35 of the stipule 30 may be distributed in a matrix shape.

[0139] Similar to the arrangement and distribution of the external contacts 34, the lattice shape formed by the multiple internal contacts 35 can correspond to the shape of the inner surface of the abutment wall 31. For example, the inner surface of the abutment wall 31 can be circular, elliptical or square, etc., and the lattice shape formed by the multiple internal contacts can also basically be a corresponding circle, ellipse or square.

[0140] The internal contacts 35 distributed in a dot matrix are conducive to setting up a sensing device 40 with multiple sensing sites in the cavity of the stipule 30, which is conducive to transmitting the squeezing signals from the external contacts 34 at different positions to the sensing device 40, and is conducive to improving the reliability and accuracy of the smart glasses 10 in determining the user's wearing status.

[0141] One end of the internal contact 35 is connected to the inner wall of the abutting wall 31 of the stipule 30, and the other end of the internal contact 35 can be disposed near the sensing device 40 within the cavity of the stipule 30. In some examples, the distances between the end surfaces of the plurality of internal contacts 35 facing the sensing device 40 and the sensing device 40 are equal or substantially equal.

[0142] For example, Figure 11 or Figure 12 As shown, the end surfaces of the plurality of internal contacts 35 facing the sensing device 40 may be flat. The sensing device 40 may include a circuit board assembly, and the end surfaces of the plurality of internal contacts 35 may be parallel to the plane of the circuit board assembly.

[0143] The end surface of the internal contact 35 facing the sensing device 40 can abut against the sensing device 40. Providing this end surface as a flat surface facilitates full contact between the internal contact 35 and the sensing device 40, thereby increasing the success rate of generating a corresponding compression signal after compressing the external contact 34, and thereby improving the reliability and effectiveness of the wearing status detection function of the wear detection assembly 20. Furthermore, setting the distance from the end surface of each of the multiple internal contacts 35 contacting the sensing device 40 to the sensing device 40 to be the same simplifies the installation of the sensing device 40 within the stent 30, thereby improving the reliability and effectiveness of wearing status detection.

[0144] The number of internal contacts 35 is related to the area of the inner surface of the abutting wall 31, the size of the internal contacts 35 and the distance between different internal contacts 35. In some examples, the internal contacts 35 or the raised structures on the inner surface of the abutting wall 31 can be columnar or conical, such as cylindrical, prism-shaped, truncated cone-shaped or prism-shaped, etc., and this application does not impose any restrictions on this.

[0145] For example, the internal contact 35 can be cylindrical, and the diameter D2 of the cylinder can satisfy 1.0 mm ≤ D2 ≤ 5.0 mm. For example, D2 can be 3.0 mm. In this case, the number n2 of the internal contact 35 on the inner surface of the abutting wall 31 of the first nose pad or the second nose pad can satisfy 6 ≤ n2 ≤ 80. For example, n2 can be 12, 24, 50, or 75.

[0146] In one possible implementation, the external contact 34 on the abutting wall 31 is arranged corresponding to the internal contact. In this case, the shapes and sizes of the internal contact 35 and the external contact 34 can be set to be the same, which is conducive to improving the production efficiency of the support leaf 30.

[0147] refer to Figure 10 In some examples, a first through hole 321 may be provided on the mounting wall 32 , and the first through hole 321 may be used as a mounting channel for components and / or structures such as the sensing device 40 housed in the cavity of the stent 30 .

[0148] Combine Figure 8 and Figure 10 A second through hole 331 can be opened on the side wall 33, and the second through hole 331 can be used as a vent. When the abutting wall 31 of the stipule 30 is squeezed, the setting of the second through hole 331 can enable the gas in the inner cavity of the stipule 30 to be discharged from the cavity in time, thereby facilitating the corresponding deformation of the abutting wall 31, which is beneficial to the contact between the internal contact 35 and the sensing device 40, and is beneficial to the realization of the detection function of the wearing detection component 20.

[0149] In some examples, the abutment wall 31, the mounting wall 32, and the side wall 33 of the stipule 30 may be integrally formed, or in other words, the external contact 34 and the internal contact 35 on the stipule 30 may be integrally formed with the body of the stipule 30. For example, the stipule 30 may be made of a material such as resin and / or silicone, for example, polyurethane, polyacrylic resin, etc.

[0150] The stipule 30 is prepared by an integrated molding process, which is beneficial to simplifying the preparation process of the stipule 30 and the wearing detection component 20 and is beneficial to improving the production efficiency of the smart glasses 10.

[0151] In some examples, the nose pad 21 may further include a stem 50. In some scenarios, the stem 50 may also be considered as the fixing portion of the nose pad 21 mentioned above. Figure 13 As shown, the stem 50 may include a fixed end 51 and a supporting end 53, which are located at opposite ends of the stem 50. The fixed end 51 can be used to achieve relative fixation between the stem 50 and the nose bracket 22, etc., and the supporting end 53 can be used to support the sensing device 40. For example, the stem 50 can be approximately dumbbell-shaped, but this embodiment of the present application does not impose specific limitations on this.

[0152] In some examples, the support stem 50 may further include a connecting portion 52 , and the aforementioned fixed end 51 and support end 53 are located at both ends of the connecting portion 52 and are fixedly connected to the connecting portion 52 respectively.

[0153] In some examples, the projections of the fixed end 51 and the connecting portion 52 of the support stem 50 in the plane where the supporting end 53 is located both fall within the range of the supporting end 53, and the projection of the connecting portion 52 in the plane where the supporting end 53 is located falls within the range of the projection of the fixed end 51 in the plane where the supporting end 53 is located.

[0154] In other words, the direction in which the fixed end 51, the connecting portion 52, and the supporting end 53 are connected to each other is considered the axial direction of the buttress 50, and the direction perpendicular to the axial direction is considered the radial direction of the buttress 50. The radial dimensions of the supporting end 53 and the radial dimensions of the fixed end 51 can both be larger than the radial dimensions of the connecting portion 52. The radial dimensions of the supporting end 53 can also be larger than the radial dimensions of the fixed end 51.

[0155] In some examples, the side of the support end 53 that supports the sensing device 40 may be flat, thereby facilitating the installation of the sensing device 40 and facilitating the contact between the internal contact 35 and the sensing device 40 .

[0156] In some examples, such as Figure 13 and Figure 14 As shown, a connecting channel 54 may be provided inside the support stem 50, and the connecting channel 54 may be used to connect the inner cavity of the stipule 30 with the external space of the stipule 30. In other words, the openings at both ends of the connecting channel 54 may be located on the end surfaces of the fixed end 51 and the supporting end 53 of the support stem 50, respectively.

[0157] Exemplarily, the connection channel 54 can be used to accommodate a portion of the cable 23 , or in other words, the cable 23 can partially pass through the connection channel 54 , and one end of this portion of the cable 23 can extend into the inner cavity of the stent 30 and be electrically connected to the sensing device 40 .

[0158] Figure 15The figure shows the assembled structure of the sensing device 40, the support stem 50, the cable 23, and the nose bracket 22. The sensing device 40 can be placed near the internal contact 35 within the cavity of the support leaf 30. The sensing device 40 can be supported on the support end 53 of the support stem 50. The side of the support end 53 facing away from the sensing device 40 can abut the inner surface of the mounting wall 32 of the support leaf 30.

[0159] Combine Figure 13 The fixed end 51 of the support stem 50 can be set on the outside of the stent 30, the supporting end of the support stem 50 can be accommodated in the cavity of the stent 30, the side of the supporting end 53 away from the fixed end 51 can face the internal contact 35 of the stent 30, and the side of the supporting end 53 close to the fixed end 51 can abut against the inner surface of the mounting wall 32 of the stent 30.

[0160] In some examples, the cable 23 may include a first connecting segment 231 , which may be accommodated in a connecting channel 54 opened inside the support stem 50 , and the first connecting segment 231 may be electrically connected to the sensing device 40 .

[0161] In some examples, the mounting wall 32 of the support leaf 30 can be mounted on the outside of the connecting portion 52 of the support stem 50 through a first through hole 321 provided thereon, or in other words, the connecting portion 52 of the support stem 50 can pass through the first through hole 321 of the mounting wall 32 of the support leaf 30 .

[0162] In some examples, the annular nose pad seat 222 of the nose pad 22 can be mounted on the outer periphery of the connecting portion 52 of the support stem 50 .

[0163] In one possible implementation, the radial dimension of the connecting portion 52 of the support stem 50 can be slightly larger than the sum of the thickness of the mounting wall 32 (or the depth of the first through hole 321) and the thickness of the nose pad seat 222, so that the mounting wall 32 and the nose pad seat 222 can be clamped between the supporting end 53 and the fixed end 51 of the support stem 50.

[0164] like Figure 16 As shown, the sensing device 40 can be a layered structure, or in other words, the sensing device 40 can be made of multiple layers of materials. In some examples, the sensing device 40 can include an abutment panel 41, an insulating layer 43, and a circuit board 45. The abutment panel 41 can be positioned near the internal contact 35, the circuit board 45 can be positioned near the support end 53 of the support stem 50, and the insulating layer 43 is located between the abutment panel 41 and the circuit board 45.

[0165] In some examples, the side of the abutment panel 41 facing the insulating layer 43 may be provided with a plurality of first electrodes 42 distributed in a lattice pattern, and the side of the circuit board 45 facing the insulating layer 43 may be correspondingly provided with a plurality of second electrodes 46 distributed in a lattice pattern. When the external contact 34 of the stipule 30 is not squeezed, the first electrode 42 on the abutment panel 41 and the second electrode 46 on the circuit board 45 can be separated by the insulating layer 43. In this state, the first electrode 42 and the second electrode 46 are not conductive, and the wearing detection component 20 does not generate a squeeze signal. When the external contact 34 is squeezed, the internal contact 35 can contact or abut the abutment panel 41. In this case, the first electrode 42 on the abutment panel 41 corresponding to the internal contact 35 can be conductive with the second electrode 46 on the circuit board 45, so that the wearing detection component 20 can generate a corresponding squeeze signal.

[0166] Exemplarily, the sensing device 40 may be a membrane switch, or a membrane touch switch. In this case, a plurality of fourth through holes may be provided on the insulating layer 43, and the positions of the fourth through holes correspond to the positions of the first electrodes 42 on the abutting panel 41. When the internal contact 35 presses against the abutting panel 41, the first electrode 42 on the abutting panel 41 may approach the second electrode 46 on the circuit board 45 through the fourth through hole until the first electrode 42 and the second electrode 46 are in contact and conductive. In this way, the wearing detection component 20 may emit a current or voltage signal generated by the conductive connection between the first electrode 42 and the second electrode 46. This current or voltage signal may be regarded as a compression signal reflecting that the surface of the stipule 30 is compressed. The signal is transmitted to the processing unit of the smart glasses 10 via the cable 23 and is then captured.

[0167] For example, the sensing device 40 may be a piezoelectric switch. In this case, a piezoelectric element may be disposed on the insulating layer 43 at a position corresponding to the first electrode 42 or the second electrode 46. The piezoelectric element includes two opposing surfaces, referred to as a first characteristic surface and a second characteristic surface. The first characteristic surface may face the first electrode 42, and the second characteristic surface may face the second electrode 46. When the internal contact 35 is not compressed, there is no electrical continuity between the two opposing characteristic surfaces of the piezoelectric element, and no electrical continuity between the first electrode 42 and the second electrode 46. When the internal contact 35 is squeezed, the internal contact 35 squeezes the piezoelectric element, and an induced electric potential is generated in the piezoelectric element due to the force, and the first characteristic surface and the second characteristic surface are conductive. The squeezing of the internal contact 35 will also shorten the distance between the abutting panel 41 and the insulating layer 43, as well as the distance between the insulating layer 43 and the circuit board 45, until the first electrode 42 can contact (conduct) with the first characteristic surface, and the second electrode 46 can contact (conduct) with the second characteristic surface, so that the first electrode 42 and the second electrode 46 are conductive through the piezoelectric element in the conductive state.

[0168] In some examples, the piezoelectric element may be composed of piezoelectric materials, including inorganic piezoelectric materials and / or organic piezoelectric materials. Inorganic piezoelectric materials may include silicon dioxide crystals, lithium niobate crystals, lithium tantalate crystals, lead metaniobate crystals, lead zirconate titanate ceramics, or potassium sodium niobate ceramics. Organic piezoelectric materials may also be called piezoelectric polymers, such as vinylidene fluoride and its copolymers.

[0169] For example, the sensing device 40 may be a pressure sensor that can be used to detect pressure values in different areas under pressure. The pressure values in different areas can be transmitted to the processing unit of the smart glasses 10 via the cable 23. When the internal contact 35 is not pressing the sensing device 40, the pressure values detected in different areas of the sensing device 40 can all be default values or initial values (e.g., zero). When the internal contact 35 presses the sensing device 40, the sensing device 40 can detect the pressure value of the local area where the internal contact 35 presses the sensing device 40.

[0170] The smart glasses 10 may be provided with a critical pressure value, which can be used to indicate the minimum pressure value at which the internal contacts 35 of the smart glasses 10 squeeze the sensing device 40 when the smart glasses 10 are being worn. Based on the magnitude relationship between the received measured pressure value and the aforementioned critical pressure value, the smart glasses 10 may determine whether the internal contacts 35 corresponding to the measured pressure value meet the conditions for indicating that the smart glasses 10 are being worn. For example, if the measured pressure value is greater than or equal to the critical pressure value, the smart glasses 10 may determine that the internal contacts 35 corresponding to the measured pressure value can indicate that the smart glasses 10 are being worn; if the measured pressure value is less than the critical pressure value, the smart glasses 10 may determine that the internal contacts 35 corresponding to the measured pressure value cannot indicate that the smart glasses 10 are being worn.

[0171] In some examples, the sensing device 40 may further include an output port 44, which may be connected to the cable 23 of the wearing detection component 20. The electrical signal generated by the membrane switch, piezoelectric switch, or pressure sensor may be output by the output port 44 and transmitted via the cable 23 to other electronic components of the smart glasses 10, such as the motherboard of the smart glasses 10.

[0172] In some examples, the sensing device 40 may also be another type of electronic component, and the connection or disconnection of different points within the sensing device 40 may be triggered by a displacement threshold or a pressure threshold. In other words, when the pressure exerted by the internal contact 35 on the sensing device 40 meets certain preset conditions, or when the displacement caused by the internal contact 35 pushing the internal structure of the sensing device 40 meets certain preset conditions, some nodes in the internal circuit of the sensing device 40 may be turned on and generate corresponding current or voltage signals.

[0173] Through the cooperation of the external contacts 34, the internal contacts 35 and the multi-layer structure of the sensing device 40, in response to the external contacts 34 being compressed, the sensing device 40 can generate a corresponding electrical signal at the position of the compressed external contacts 34. In this way, when the user wears the smart glasses 10, the user's nose bridge can abut against some or all of the multiple external contacts 34, and the sensing device 40 can generate a corresponding electrical signal to reflect that the external contacts 34 are squeezed. The smart glasses 10 can determine its own wearing status based on these electrical signals.

[0174] In some examples, the smart glasses 10 can determine their own wearing status based on the strength of the received electrical signal (such as the size of the voltage signal or the size of the current signal) or the presence or absence of the electrical signal (the number of pathways).

[0175] For example, the smart glasses 10 can determine the number of squeezed external contacts 34 based on the size of the received current, and determine whether the smart glasses 10 are in a worn state based on the number of squeezed external contacts 34 or the proportion of the number of squeezed external contacts 34 to the total number of external contacts 34.

[0176] For example, the current generated by squeezing a single external contact 34 may be I1, and the current received by the smart glasses 10 may be Ir. Thus, the number n of squeezed external contacts 34 may be the ratio of Ir to I1. If the number n of squeezed external contacts 34 is greater than or equal to a first threshold, the smart glasses 10 may determine that the smart glasses 10 are in a worn state. If the number n of squeezed external contacts 34 is less than the first threshold, the smart glasses 10 may determine that the smart glasses 10 are not in a worn state.

[0177] For another example, the current generated when all external contacts 34 are squeezed may be Is, and the current received by the smart glasses 10 may be Ir. Thus, the ratio r between the number of squeezed external contacts 34 and the total number of external contacts 34 may be the ratio of Ir to Is. If the ratio r of the number of squeezed external contacts 34 to the total number of external contacts 34 is greater than or equal to a second threshold, the smart glasses 10 may determine that the smart glasses 10 are in a worn state. If the ratio r of the number of squeezed external contacts 34 to the total number of external contacts 34 is less than the second threshold, the smart glasses 10 may determine that the smart glasses 10 are not in a worn state.

[0178] Figure 17A graph illustrating the relationship between the squeeze signal received by the smart glasses 10 and time during a single wearing process is provided. In the graph, Sc may represent a critical value for the number of squeezed external contacts 34 or a critical value for the ratio of squeezed external contacts 34 that can be used to determine that the smart glasses 10 are in the worn state.

[0179] During the time period t0-t1, the squeeze signal received by the smart glasses 10 is zero, or in other words, a null signal is received during this period. In this case, the smart glasses 10 can be considered to be not being worn by the user. During the time period t1-t2 and the time period t2-t3, the squeeze signals received by the smart glasses 10 are S1 and S2, respectively. S1 or S2 can represent the number n of squeezed external contacts 34, or can also be used to represent the ratio r of the number of squeezed external contacts 34 to the total number of external contacts 34. Since both S1 and S2 are less than Sc, it can be determined that the smart glasses 10 are still not being worn during the time period t1-t2 and the time period t2-t3. During the time period t3-t4, the squeeze signal received by the smart glasses 10 is S3, and the value of S3 is greater than Sc, which can be used to determine that the smart glasses 10 are being worn during the time period t3-t4. Similarly, during the time period t4-t5, the squeeze signal received by the smart glasses 10 is a null signal, and the smart glasses 10 can determine that they are not being worn.

[0180] exist Figure 17 In the example shown, the time period t0-t1 can be the time period before the user puts on the smart glasses 10, the time period t1-t3 can be regarded as the process of the user adjusting the wearing posture of the glasses while wearing the smart glasses 10, the time period t3-t4 can be regarded as the process of the user wearing the smart glasses 10, and the time period t4-t5 can be regarded as the process of the user taking off the smart glasses 10.

[0181] In some examples, the smart glasses 10 can determine their wearing status based on the number of electrical signals received within a preset time period. If one external contact 34 is squeezed, the sensing device 40 can send an electrical signal to the processing unit of the smart glasses 10. If multiple external contacts 34 are squeezed, the sensing device 40 can send a corresponding number of electrical signals to the processing unit of the smart glasses 10. To a certain extent, the number of electrical signals received by the smart glasses 10 within a period of time can reflect the number of external contacts 34 on the studs 30 that were squeezed during that period, and thus can reflect the wearing status of the smart glasses 10.

[0182] Exemplarily, the smart glasses 10 may count the number of electrical signals received within the time period at the same interval. If the total amount of electrical signals received within the time period is greater than or equal to a third threshold, it is determined that the smart glasses 10 are in a worn state within the time period. If the total amount of electrical signals received within the time period is less than the third threshold, it is determined that the smart glasses 10 are not in a worn state within the time period.

[0183] like Figure 18 As shown, in the first time interval (0-T) and the fourth time interval (3T-4T), the number of electrical signals received by the smart glasses 10 is less than the critical number Nc, which can be used to determine that the smart glasses 10 are not being worn during these two time periods; in the second time interval (T-2T) and the third time interval (2T-3T), the number of electrical signals received by the smart glasses 10 is greater than the critical number Nc, which can be used to determine that the smart glasses 10 are being worn during these two time periods. The critical number Nc can be used to indicate the minimum number of electrical signals received by the smart glasses 10 within a preset time interval when the smart glasses 10 are being worn, or the critical number Nc can be used to indicate the minimum number of external contacts 34 that are squeezed when the smart glasses 10 are being worn.

[0184] In some examples, the smart glasses 10 may first independently determine the electrical signals generated in the two nose pads 21 to determine the wearing status of the smart glasses indicated by the two nose pads 21, and then determine the wearing status of the smart glasses 10 based on the results of the two nose pads 21. For example, if both nose pads 21 indicate that the smart glasses 10 are being worn, the smart glasses 10 may determine that they are being worn.

[0185] For the same smart glasses 10, the compression state of different areas of the stipule 30 in contact with the user's nose bridge may be different under different wearing postures of the same user. The compression state of different areas of the stipule 30 in contact with the user's nose bridge when worn by different users may also be different. By providing a plurality of external contacts 34 spaced apart from each other on the first surface of the stipule 30, and utilizing internal contacts 35 corresponding to the external contacts 34 to transmit the compression signal of the external contacts 34 to the sensing device 40 inside the stipule 30, these signals are then transmitted to the processing unit of the smart glasses 10 for determining the wearing state of the smart glasses 10. The above technical solution can be applied to different wearing postures and different users, and the structure of wearing state detection is more reliable, which is conducive to enabling the smart glasses 10 to respond to the user's operation in a timely manner after the user puts on the glasses, and is conducive to reducing energy waste caused by wearing state detection errors, and is conducive to improving the energy utilization efficiency of the smart glasses 10.

[0186] Based on the above-mentioned smart glasses 10, an embodiment of the present application also provides a wearing detection method. The multiple external contacts 34 set on the stipule 30 can feedback multiple squeezing signals. The smart glasses 10 can determine the wearing status of the smart glasses 10 based on the multiple squeezing signals feedback by the stipule. The wearing status of the smart glasses 10 determined by this method is more accurate, the functional reliability of the smart glasses 10 is higher, and the energy utilization efficiency is higher.

[0187] S101 : Acquire a squeeze signal in response to a user operation.

[0188] The squeeze signal may refer to a signal caused by squeezing the external contact 34 on the outer surface of the stipule 30 of the smart glasses 10 . In some scenarios, the squeeze signal may also be referred to as a contact signal.

[0189] The squeeze signal may be an electrical signal generated by the sensing device 40 in the stipule 30 being squeezed or the like. The sensing device 40 may be one or more of a membrane switch, a piezoelectric switch, a pressure sensor, and the like.

[0190] In some examples, in response to a user's wearing operation, the smart glasses 10 obtain a squeeze signal caused by squeezing the external contact 34 on the stud 30 .

[0191] When a user wears the smart glasses 10, some or all of the external contacts 34 of the smart glasses 10 will come into contact with the skin near the bridge of the user's nose. This creates an interaction force between the bridge of the user's nose and the external contacts 34. This force will cause the external contacts 34 to deform in shape, generating internal stress. This internal stress can partially or completely act on the internal contacts 35 connected to the external contacts 34, causing displacement and / or deformation of the internal contacts 35. When the internal contacts 35 come into contact with or press against the sensing device 40 within the stipule 30, the sensing device 40 will generate a corresponding electrical signal in the squeezed area, which can be considered the squeezing signal.

[0192] In the above solution, the wearing detection function of the wearing detection component 20 of the smart glasses 10 can be in a normally open state, or in other words, after the smart glasses 10 are powered on, the wearing detection function of the smart glasses 10 is in an available state.

[0193] Since the wearing status of the smart glasses 10 can be detected more reliably by the wearing detection component 20 provided in this application, setting the wearing detection function of the wearing detection component 20 to a state where it can be used upon power-on is beneficial to improving the efficiency of the smart glasses 10 in determining their own wearing status and to improving the response speed of the smart glasses 10 to user operations.

[0194] In some examples, in response to a request to confirm the wearing state of the smart glasses 10 , the smart glasses 10 obtain a squeeze signal caused by squeezing an external contact on the stud 30 .

[0195] In some scenarios, the smart glasses 10 may also be provided with other wearing status detection modules or devices, for example, referred to as reference modules. The wearing status detection function of the reference module may be implemented based on the capacitance principle or the proximity light sensor principle. In one possible implementation, the reference module is the default wearing status detection module of the smart glasses 10. If the reference module cannot determine the wearing status of the smart glasses 10, the smart glasses 10 may enable the wearing status detection module 20 provided in the embodiment of the present application and use the wearing status detection module 20 to detect the wearing status of the smart glasses 10. In this case, the operation or command of the smart glasses 10 to enable the wearing status detection module 20 may be regarded as the request for confirming the wearing status of the smart glasses 10.

[0196] Implementing the detection of the wearing status of the smart glasses 10 through multiple detection modules is beneficial to improving the accuracy of the wearing status detection results of the smart glasses 10 to a certain extent.

[0197] S102: Determine the wearing state according to the squeezing signal.

[0198] The wearing state, or the wearing state of the smart glasses 10, may refer to the state in which the smart glasses 10 are worn or not worn by the user. In some scenarios, the wearing state may also refer to different wearing postures of the smart glasses 10 when worn by the user. In some scenarios, the wearing state may also refer to the state in which the smart glasses 10 are worn by different users.

[0199] The squeezing signal may be generated by the sensing device 40 in the stipule 30 and transmitted to the processing unit of the smart glasses 10 via the cable 23 . The processing unit of the smart glasses 10 may determine the wearing status of the smart glasses 10 based on the squeezing signal.

[0200] In some examples, the smart glasses 10 can determine the number or ratio of squeezed external contacts 34 based on the strength of the squeeze signal (e.g., the magnitude of the current or voltage) or the presence or absence of the electrical signal (the number of pathways). If the number or ratio of squeezed external contacts 34 is greater than or equal to a preset threshold, the smart glasses 10 can determine that they are being worn. If the number or ratio of squeezed external contacts 34 is less than the preset threshold, the smart glasses 10 can determine that they are not being worn.

[0201] In some examples, the smart glasses 10 can determine the number of squeezed external contacts 34 based on the number of squeeze signals detected within the same time period. If the number of squeezed external contacts 34 is greater than or equal to a preset threshold, the smart glasses 10 can determine that they are being worn. If the number of squeezed external contacts 34 is less than the preset threshold, the smart glasses 10 can determine that they are not being worn.

[0202] In some examples, when the smart glasses 10 determine that they are being worn by a user, the smart glasses 10 may perform a preset operation, such as displaying preset information or broadcasting preset information. If the smart glasses 10 determine that they are not being worn by a user, the smart glasses 10 may end the wearing status detection.
