Description

Technical Field

[0001] This application relates to the field of terminal device technology, and in particular to a hinge assembly and smart glasses. Background Technology

[0002] The frames and temples of smart glasses fold together via hinges. The frames integrate electronic modules such as cameras, while the temples house power supplies and sensors. Signal transmission and power supply require electrical connections via flexible circuit boards (FPCs). Current technology typically places the FPCs and other components on the outer surface of the hinges. This design makes the FPCs susceptible to deformation and breakage due to compression, and also exposes them to corrosion. Furthermore, external wiring occupies space, hindering the miniaturization of the hinges. Therefore, further optimization of the mechanical component layout of smart glasses is needed to ensure the protection and reliable connection of the circuitry within the glasses. Utility Model Content

[0003] This application provides a hinge assembly and smart glasses, which further optimizes the mechanical component layout of smart glasses and ensures the protection and reliable connection of the circuits in smart glasses.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] In a first aspect, this application provides a hinge assembly for use in smart glasses. The hinge assembly is used to connect the frame and temples of the smart glasses. The hinge assembly includes a first connector and a second connector, wherein the first connector is used to connect the frame and the second connector is used to connect the temples.

[0006] The first connector has a wiring cavity, and the wiring cavity has a first inlet and a first outlet;

[0007] The second connector is rotatably connected to the outside of the first connector. The second connector includes a receiving groove and a wiring groove with different groove directions and interconnected groove walls. The receiving groove surrounds the wiring cavity, and the wiring groove is connected to the first inlet and the first outlet.

[0008] According to the hinge assembly provided in the embodiments of this application, the hinge assembly includes a first connector and a second connector that are rotatably connected. The first connector is connected to the frame of the smart glasses, and the second connector is connected to the temple of the smart glasses. In this way, the opening and folding of the frame and temple of the smart glasses can be effectively realized by the rotatably connected first connector and second connector. Since the second connector connected to the temple is rotatably connected to the outside of the first connector, the second connector is provided with a receiving groove and a wiring groove with interconnected groove walls and different groove directions. The receiving groove surrounds the wiring cavity. The wiring groove is connected to the first inlet and the first outlet of the wiring cavity in the first connector. Based on this, the FPC and other components in the smart glasses can enter the wiring cavity from the temple through the wiring groove from the first inlet of the wiring cavity and exit from the first outlet of the wiring cavity. The cooperation of the first connector and the second connector avoids the direct exposure of the FPC and other components, preventing the FPC and other components from being exposed and corroded.

[0009] Furthermore, because the second connector connecting to the temple is located outside the first connector connecting to the frame, and the second connector has accommodating grooves and wiring grooves with different groove directions and interconnected groove walls, the entire space of the wiring cavity can serve as wiring space for FPC and other components. This large component space effectively avoids the risk of compression deformation or even breakage of the FPC and other components by the hinge assembly. In addition, since the second connector does not have inlets and outlets corresponding to the first inlet and first outlet in the first connector, the rotation of the first and second connectors during the unfolding and folding of the smart glasses will not directly rub against the FPC and other components. Moreover, because the walls of the wiring groove and the accommodating groove are interconnected, the FPC and other components will not rotate with the second connector during temple rotation, eliminating localized stress caused by rotational friction. This optimizes the mechanical structure of the hinge assembly, ensures the compactness of the hinge structure, and simultaneously achieves circuit protection and reliable connection, improving the user experience.

[0010] In one possible implementation, the hinge assembly further includes a pivot and a snap-fit ​​element, wherein the first connector and the second connector are rotatably connected via the pivot and the snap-fit ​​element, and the snap-fit ​​element is used to snap onto both ends of the pivot.

[0011] In one possible implementation, the wall of the wiring cavity is provided with opposing first through holes, the wall of the receiving groove is provided with opposing second through holes, one end of the rotating shaft passes through the first through hole and the second through hole, and the snap-fit ​​is snapped onto both ends of the rotating shaft.

[0012] Based on the above possible implementation methods, one end of the rotating shaft can be passed through the second through hole and the first through hole in sequence, and then the rotating shaft can be secured with a snap-fit ​​device. Alternatively, one end of the rotating shaft can be passed through the first through hole and the second through hole in sequence, and then the rotating shaft can be secured with a snap-fit ​​device. Regardless of the connection method, only the snap-fit ​​device exists in the wiring cavity, achieving a compact rotational connection. At the same time, the design of securing the rotating shaft with a snap-fit ​​device can effectively avoid the risk of unstable connection between the first and second connecting parts due to nut loosening, as is the case with methods such as screw and nut, thus improving the reliability and stability of the connection.

[0013] In one possible implementation, the snap-fit ​​component includes a first snap-fit ​​component and a second snap-fit ​​component. One end of the rotating shaft is integrally formed with the first snap-fit ​​component, and the other end of the rotating shaft is provided with a slot. The other end of the rotating shaft passes through the first through hole and the second through hole, and the second snap-fit ​​component is snapped into the slot.

[0014] It should be understood that after one end of the rotating shaft is integrally formed with the first snap-fit ​​component, it can form a screw or a rotating shaft with the first snap-fit ​​component at one end. In the case of a rotating shaft with the first snap-fit ​​component, the first snap-fit ​​component can be fixedly connected to one end of the rotating shaft as a stop.

[0015] In one possible implementation, the hinge assembly further includes a washer that passes through the pivot and is located between the first through hole and the second through hole.

[0016] Alternatively, the gasket can be made of non-metallic materials such as rubber or plastic. In other examples, the gasket can also be made of metallic materials (such as steel, copper, aluminum, etc.) or composite materials (such as metal and rubber composites).

[0017] Based on the above possible implementation methods, during the process of rotating the shaft through the first through hole and the second through hole to connect the first connector and the second connector, a washer is added between the first through hole and the second through hole. This can provide damping force for the temples during opening and closing without affecting the wiring space of the wiring cavity. This avoids the situation where the temples quickly fold before the user puts them on their head after opening the smart glasses, thus improving the user experience.

[0018] In addition, the gasket placed between the first through hole and the second through hole can also play a role in cushioning and shock absorption during the unfolding or folding of the smart glasses, reducing wear between the first connector and the second connector, increasing the wear resistance of the connector, and extending the service life of the smart glasses.

[0019] In one possible implementation, the hinge assembly further includes an elastic element;

[0020] The second connector also includes a first mounting groove, the groove wall of the receiving groove serves as the bottom of the first mounting groove, and one end of the elastic member is fixedly connected to the groove wall of the first mounting groove.

[0021] The wiring cavity is provided with an abutment post, which is used to abut against the other end of the elastic element during the unfolding of the temple.

[0022] Based on the above possible implementation methods, since the groove direction of the first mounting groove is the same as the groove direction of the receiving groove, after the first connector and the second connector are rotatably connected, the first mounting groove can be set above or below the receiving groove. In this way, after the elastic element is set in the first mounting groove, the setting of the elastic element does not occupy the space of the wiring cavity, effectively increasing the wiring space of FPC and other devices.

[0023] Furthermore, it should be noted that after the first and second connecting parts are rotatably connected, one end of the elastic element is fixedly connected to the wall of the first mounting groove, while the other end of the elastic element is not fixedly connected. In this way, when the smart glasses are in the folded state, the elastic element is not under force, and the temples can be folded by relying on the rotatable connection between the first and second connecting parts. When the smart glasses are in the unfolded state, the temples drive the second connecting part to rotate, so that the other end of the elastic element can abut against the abutment post. In this way, as the elastic element is compressed and the temples are unfolded, the unfolding angle of the temples relative to the frame can be effectively controlled until the elastic element is fully compressed and the unfolding angle of the temples reaches its maximum.

[0024] Furthermore, when a user wears the smart glasses, the temples unfold, the elastic element is compressed, and the temples fold due to the elastic force of the second connector. This allows the smart glasses to effectively adapt to users with different head shapes or head circumferences, thus meeting the usage needs of different users.

[0025] It's easy to understand that a design where one end of the elastic element is fixed and the other end is not is simple in mechanical structure, occupies little space, and is both practical and easy to process hinge components.

[0026] Optionally, the specific type of the elastic element can be any one of elastic band, spring, torsion spring, or elastic sheet.

[0027] Optionally, a protrusion may be provided in the first mounting groove, and one end of the elastic element passes through the protrusion and is fixedly connected in the first mounting groove.

[0028] Optionally, the length of the protrusion is less than or equal to the length of the elastic element when it is fully compressed.

[0029] In one possible implementation, the hinge assembly further includes a housing having a first opening, the housing surrounding the first connector, and the second connector extending through the first opening.

[0030] Alternatively, the sidewalls of the housing can be directly fixed to the top of the shaft by means of adhesive or other methods.

[0031] In one possible implementation, the hinge assembly further includes a fastener, a third through hole is provided on the side wall of the housing, a second mounting groove is provided at one end of the pivot, and the fastener passes through the third through hole and is disposed in the second mounting groove for connecting the housing and the pivot.

[0032] Optionally, a washer may also be provided between the third through hole and the fastener.

[0033] Based on the above possible implementation methods, regardless of whether the smart glasses are in an unfolded or folded state, the FPC and other components in the corresponding area of ​​the hinge assembly are completely encapsulated in the hinge assembly, avoiding the situation where the FPC and other components are fully or partially exposed, effectively preventing the external environment from corroding the FPC and other components, further reducing the possibility of device damage, and improving the reliability of the smart glasses connection.

[0034] Furthermore, in the above possible implementations, the pivot can be used not only for fixing the housing but also for rotating the first connector and the second connector, effectively reducing the space required for the hinge assembly while also lowering the structural design and manufacturing costs.

[0035] In one possible implementation, the hinge assembly further includes an angle detection component for detecting the opening angle between the frame and the temple.

[0036] In one possible implementation, the angle detection component includes a magnetic sensor and a first magnet, the magnetic sensor being disposed on the first connector and the first magnet being disposed on the second connector; or...

[0037] The magnetic sensor is disposed on the second connector, and the first magnet is disposed on the first connector.

[0038] In one possible implementation, the first connector further includes a third mounting groove, the bottom of which has a first opening that communicates with the first outlet. The second connector further includes a fourth mounting groove, the opening direction of which is opposite to the opening direction of the wiring groove.

[0039] The magnetic sensor is disposed at the bottom of the third mounting slot, and the first magnet is disposed in the fourth mounting slot; or,

[0040] The magnetic sensor is located in the fourth mounting slot, and the first magnet is located at the bottom of the third mounting slot.

[0041] Based on the above possible implementation methods, the positional relationship between the magnetic sensor and the first magnet can be changed by rotating the temples, thereby effectively detecting the opening and closing angle of the temples in the smart glasses. In practical applications, the state of the smart glasses can be determined based on the opening and closing angle of the temples (for example, a temple opening angle of 60°-110° controls the smart glasses to be in working state so that the user can use the smart glasses; conversely, the smart glasses can be in sleep state to save energy). This facilitates the setup of the smart glasses.

[0042] Optionally, the third mounting slot can also be used to connect to the frame. For example, a mounting interface corresponding to the third mounting slot can be provided on the frame, and the frame and the first connector can be connected by the snap-fit ​​between the third mounting slot and the mounting interface.

[0043] Optionally, a mounting through hole may be provided on the second connector to allow the second connector to be connected to the temple of the mirror.

[0044] Alternatively, the second connector can also be integrally formed with the temple.

[0045] Optionally, the combination of devices used to detect the opening angle of the first connector and the second connector can also be a rotating electrode and a fixed electrode, or a gyroscope and an accelerometer, etc.

[0046] For example, taking the rotating electrode as an arc-shaped capacitor plate and the fixed electrode as a corresponding plate array as an example, the plate array can be set on the first connector and the arc-shaped capacitor plate can be set on the second connector. During the rotation of the first connector and the second connector, the overlapping area between the two plates will change as the first connector and the second connector rotate, which will cause the capacitance value to change. In practical applications, the rotation angle between the first connector and the second connector can be calculated by the capacitance and angle calibration curve.

[0047] For example, a gyroscope can be installed on the first connector and an accelerometer can be installed on the second connector. During the rotation of the first and second connectors, the angle difference can be obtained by integrating the relative angular velocity and analyzing the attitude, thereby obtaining the rotation angle between the first and second connectors.

[0048] Secondly, this application provides a smart glasses that may include a frame, temples, and a hinge assembly as described in the first aspect or any possible implementation thereof, wherein the frame and the temples are connected by the hinge assembly.

[0049] Alternatively, the smart glasses can be augmented reality (AR) glasses, virtual reality (VR) glasses, mixed reality (MR) glasses, or AI glasses.

[0050] Optionally, the frame of the smart glasses can be fitted with loads such as waveguides, cameras, optical engines, and microphones.

[0051] The technical effects of the second aspect provided in this application can be found in the technical effects of the various alternative methods of the first aspect mentioned above, and will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0087] In the field of smart glasses technology, the folding function of the frame and temples via hinge components has become the mainstream design for smart glasses. With the increasing integration of smart modules, the frame needs to house electronic devices such as cameras and display units, while the temples need to accommodate components such as batteries, sensors, and main control chips. To achieve signal transmission and power supply between the modules in the frame and temples, a flexible printed circuit board (FPC) needs to penetrate the hinge area to connect the electronic modules within the frame with the built-in components in the temples.

[0088] In current technologies, the wiring method typically involves attaching the FPC (Flexible Printed Circuit) to the outer surface of the hinge. This design leaves the exposed section of the FPC in the hinge bending area lacking mechanical restraint. During repeated opening and closing, this makes it susceptible to deformation and bulging due to hinge component compression, and even fracture due to stress concentration. Simultaneously, the exposed FPC is vulnerable to external friction and oxidation, severely impacting signal transmission stability and device lifespan. Furthermore, traditional winding structures require additional wiring space, increasing hinge size and contradicting the need for thinner and lighter smart glasses. Therefore, there is an urgent need to design a new hinge component to further optimize the mechanical component layout of smart glasses and ensure the protection and reliable connection of the circuitry within the smart glasses.

[0089] To address the aforementioned technical issues, this application provides a hinge assembly. Through the rotatable connection of a first connector and a second connector, smooth unfolding and folding of the frame and temples are ensured. The second connector, with its interconnected but differently oriented receiving slots and wiring channels, provides ample wiring space for components such as the FPC, avoiding the risk of compression deformation or breakage due to insufficient space. Simultaneously, since the wiring channels are directly connected to the wiring cavity in the first connector, the FPC does not need to be exposed, effectively preventing external environmental corrosion of the FPC and other components. Furthermore, the absence of additional inlets and outlets in the second connector avoids friction on the FPC and other components caused by the relative rotation of the first and second connectors during unfolding and folding, further reducing the possibility of damage to the FPC and other components. Through these structural optimizations, not only is the compactness of the hinge assembly improved, but the reliability of the circuit connection and the stable operation of the smart glasses' functions are also ensured.

Figure 2 This is a schematic diagram of the overall structure of a smart glasses 1 in a folded state, according to an embodiment of this application. See also... Figure 1 and Figure 2 The smart glasses 1 may include a hinge assembly 100, a frame 200, and temples 300. The frame 200 can be connected to the temples 300 via the hinge assembly 100. In this embodiment, the hinge assembly 100 enables a rotatable connection between the frame 200 and the temples 300.

[0091] Specifically, Figure 3 This is a schematic diagram of the overall structure of a hinge assembly 100 provided in an embodiment of this application. Figure 4 This is a schematic diagram of the overall structure of a hinge assembly 100 after removing the outer shell 170, as provided in an embodiment of this application. Figure 5 This is an exploded structural diagram of a hinge assembly 100 provided in an embodiment of this application. See also... Figures 3 to 5 The hinge assembly 100 mainly includes a first connector 110 and a second connector 120 that are rotatably connected. In the smart glasses 1, the first connector 110 can be used to connect the frame 200, and the second connector 120 can be used to connect the temples 300. In this way, the first connector 110 and the second connector 120, which are rotatably connected, can effectively realize the unfolding and folding of the frame 200 and the temples 300 in the smart glasses 1.

[0092] Figure 6 This is a schematic diagram of the overall structure of a first connector 110 provided in an embodiment of this application. Figure 7 This is a schematic diagram of the overall structure of a second connector 120 provided in an embodiment of this application. See also... Figures 3 to 7The first connector 110 may include a wiring cavity 111, which has a first inlet 1111 and a first outlet 1112. The second connector 120 is rotatably connected to the outside of the first connector 110. The second connector 120 may include a receiving groove 121 and a wiring groove 122 with different groove directions and interconnected groove walls. The receiving groove 121 can be used to surround the wiring cavity 111, and the wiring groove 122 is connected to the first inlet 1111 and the first outlet 1112.

[0093] It should be understood that in the embodiments of this application, the wiring cavity 111 may be a hollow structure, and the wiring cavity 111 may be used to accommodate devices such as FPC.

[0094] In one example, the wiring cavity 111 can be cylindrical.

[0095] In other examples, the wiring cavity 111 may also be a cylinder with an outwardly convex upper (and / or lower) surface, a chamfered cylinder, or a multifaceted cylinder with sides formed by multiple rectangles. This application does not limit the specific shape of the wiring cavity 111.

[0096] The first inlet 1111 can be used for FPC and other devices to enter the wiring cavity 111; the first outlet 1112 can be used for FPC and other devices that have entered the wiring cavity 111 to exit the wiring cavity 111.

[0097] In some embodiments, the opening width of the first inlet 1111 along the rotational direction between the first connector 110 and the second connector 120 can be greater than the slot width of the receiving groove 121 along the aforementioned rotational direction. This effectively prevents the first connector 110 and the second connector 120 from directly rubbing against the FPC and other devices, and also further increases the wiring space for the FPC and other devices in the hinge assembly 100. In practical applications, it also facilitates heat dissipation for the FPC and other devices in the hinge assembly 100.

[0098] See Figure 6 In some embodiments, the opening height of the first inlet 1111 may be the same as the height of the wiring cavity 111; and / or, the opening height of the first outlet 1112 may also be the same as the height of the wiring cavity 111, wherein the height of the wiring cavity 111 can be referred to Figure 6 The height H1 in the middle. When the wiring cavity 111 is cylindrical, the height of the wiring cavity 111 can refer to the height of the cylinder. The opening height direction of the first inlet 1111 and the opening height direction of the first outlet 1112 are the same as the height direction of the wiring cavity 111.

[0099] In some embodiments, the opening height of the first inlet 1111 and / or the opening height of the first outlet 1112 may also be lower than the height of the wiring cavity 111. This application embodiment does not limit this.

[0100] In some embodiments, the opening width of the first inlet 1111 along the rotational direction between the first connector 110 and the second connector 120 can be greater than the opening width of the first outlet 1112 along the rotational direction between the first connector 110 and the second connector 120. This can effectively prevent damage to the FPC and other devices caused by the need to fold or bend the inlet to the wiring cavity 111 due to its small size.

[0101] In other embodiments, to reduce the weight of the hinge assembly 100, the opening width of the first outlet 1112 along the rotational direction between the first connector 110 and the second connector 120 may be equal to or greater than the opening width of the first inlet 1111 along the rotational direction between the first connector 110 and the second connector 120. This application does not limit this aspect.

[0102] See Figure 5 or Figure 7 The wall of the receiving groove 121 can communicate with the wall of the wiring groove 122, and the opening direction of the receiving groove 121 and the opening direction of the wiring groove 122 can be different. In this embodiment, the receiving groove 121 and the wiring groove 122 can share the same bottom, that is, the bottom of the receiving groove 121 can be used as the bottom of the wiring groove 122, and the bottom of the wiring groove 122 can also be used as the bottom of the receiving groove 121.

[0103] As an example, and not a limitation, when the second connector 120 is a cuboid (or cube), it can also be understood that the receiving groove 121 and the wiring groove 122 are respectively located on two adjacent sides of the cuboid. Based on this, it can be said that the groove opening direction of the receiving groove 121 and the groove opening direction of the wiring groove 122 are perpendicular to each other.

[0104] In some embodiments, both the receiving groove 121 and the wiring groove 122 in the second connector 120 can be U-shaped grooves.

[0105] In some embodiments, the height of the receiving groove 121 may be equal to the height of the wiring groove 122, wherein the height of the receiving groove 121 and / or the height of the wiring groove 122 may both be adapted to the height of the wiring cavity 111.

[0106] In other embodiments, the height of the receiving groove 121 may not be equal to the height of the wiring groove 122. The height of the receiving groove 121 may be higher than the height of the wiring cavity 111, and / or the height of the wiring groove 122 may be lower than the height of the wiring cavity 111.

[0107] See Figure 5 or Figure 7The slot opening direction of the receiving slot 121 can be seen from direction A indicated by arrow, and the slot opening direction of the wiring slot 122 can be seen from direction B indicated by arrow. The slot opening direction of the receiving slot 121 is different from that of the wiring slot 122.

[0108] It's not hard to understand. Figure 4 The schematic diagram of the hinge assembly 100 shown can be a schematic diagram of the smart glasses 1 in the folded state, based on Figure 4 When the smart glasses 1 are in a folded state, the opening direction (i.e., direction A) of the receiving groove 121 of the hinge assembly 100 can be parallel (or substantially parallel) to the first inlet 1111 on the wiring cavity 111 in the first connector 110, and can also be parallel (or substantially parallel) to the first outlet 1112 on the wiring cavity 111; while the opening direction (i.e., direction B) of the wiring groove 122 can be perpendicular (or substantially perpendicular) to the aforementioned first inlet 1111 (or first outlet 1112).

[0109] For example Figure 8 The diagram shown is a structural schematic of the hinge assembly 100 of a smart glasses 1 in the unfolded state according to an embodiment of this application. See also... Figure 8 When the smart glasses 1 are unfolded, the groove direction (i.e., direction A) of the receiving groove 121 can be perpendicular (or substantially perpendicular) to the first inlet 1111 on the wiring cavity 111, and can also be perpendicular (or substantially perpendicular) to the first outlet 1112 on the wiring cavity 111; while the groove direction of the wiring groove 122 can be parallel (or substantially parallel) to the aforementioned first inlet 1111 (or first outlet 1112).

[0110] Based on the above possible implementations, since the second connector 120 connected to the temple 300 is rotatably connected to the outside of the first connector 110, the second connector 120 is provided with a receiving groove 121 and a wiring groove 122 that are connected and have different opening directions. The receiving groove 121 surrounds the outside of the wiring cavity 111, and the wiring groove 122 is connected to the first inlet 1111 and the first outlet 1112 on the wiring cavity 111 in the first connector 110. Based on this, the FPC and other devices in the smart glasses 1 can enter the wiring cavity 111 from the temple 300 through the wiring groove 122 from the first inlet 1111 and exit the wiring cavity 111 from the first outlet 1112. In this way, the cooperation of the first connector 110 and the second connector 120 avoids the direct exposure of the FPC and other devices, and prevents the FPC and other devices from being exposed and corroded.

[0111] See Figures 4 to 5 The hinge assembly 100 may also include a pivot 130 and a snap-fit ​​member 140, through which the first connector 110 and the second connector 120 can be rotatably connected.

[0112] In some embodiments, both ends of the rotating shaft 130 may be provided with slots 131. By engaging the snap-fit ​​member 140 into the slots 131 at both ends of the rotating shaft 130, the first connector 110 and the second connector 120 can be rotated together.

[0113] As one implementation, at least one first through hole 1113 can be opened on the cavity wall of the wiring cavity 111, and at least one second through hole 1211 can be opened on the groove wall of the receiving groove 121. After one end of the rotating shaft 130 passes through the first through hole 1113 and the second through hole 1211, it is respectively snapped into the slots 131 at both ends of the rotating shaft 130 by the snap-fit ​​member 140, so as to realize the rotational connection between the wiring cavity 111 and the second connector 120.

[0114] To improve the reliability and stability of the connection between the first connector 110 and the second connector 120, the number of first through holes 1113 formed on the cavity wall of the wiring cavity 111 can be two. The number of second through holes 1211 formed on the groove wall of the receiving groove 121 can also be two.

[0115] See, as an example rather than a limitation. Figure 6 A first through hole 1113 can be formed on the cavity wall of the wiring cavity 111, see [reference]. Figure 7 A second through hole 1211 can be provided on the wall of the receiving groove 121. After one end of the rotating shaft 130 passes through the first through hole 1113 and the second through hole 1211, it is snapped onto both ends of the rotating shaft 130 by the snap-fit ​​member 140, thereby realizing the rotational connection of the first connecting member 110 and the second connecting member 120.

[0116] In the actual assembly process, the order in which the rotating shaft 130 passes through the first through hole 1113 and the second through hole 1211 can be further determined according to the assembly direction of the rotating shaft 130 from the outside to the inside or from the inside to the outside. The aforementioned "outside" can refer to the outer side of the wiring cavity 111; the "inside" can refer to the inner side of the wiring cavity 111.

[0117] For example, in Figures 3 to 7 In the schematic diagram shown, if the assembly direction is from the outside in, one end of the rotating shaft 130 can pass through the second through hole 1211 and the first through hole 1113 in sequence, and then the snap-fit ​​member 140 is snapped into the slots 131 that are respectively snapped into both ends of the rotating shaft 130. Based on this, the first connecting member 110 and the second connecting member 120 are rotatably connected. Conversely, if the assembly direction is from the inside out, one end of the rotating shaft 130 can pass through the first through hole 1113 and the second through hole 1211 in sequence, and then the snap-fit ​​member 140 is snapped into the slots 131 that are respectively snapped into both ends of the rotating shaft 130. Based on this, the first connecting member 110 and the second connecting member 120 are rotatably connected.

[0118] Based on the above possible implementation methods, one end of the rotating shaft 130 can be passed through the second through hole 1211 and the first through hole 1113 in sequence, and then the rotating shaft 130 can be secured by the snap-fit ​​component 140. Alternatively, one end of the rotating shaft 130 can be passed through the first through hole 1113 and the second through hole 1211 in sequence, and then the rotating shaft 130 can be secured by the snap-fit ​​component 140. Regardless of the connection method, only the snap-fit ​​component 140 exists in the wiring cavity 111. This achieves the rotational connection between the first connector 110 and the second connector 120, and the design of the snap-fit ​​component 140 securing the rotating shaft 130 effectively avoids the risk of unstable connection between the first connector 110 and the second connector 120 due to nut loosening when using designs such as screw and nut mating, thus improving the reliability and stability of the connection.

[0119] In other embodiments, see Figure 5 Alternatively, a slot 131 can be provided at only one end of the rotating shaft 130, and the first connector 110 and the second connector 120 can be rotated by snapping the snap-fit ​​140 into the slot 131 at one end of the rotating shaft 130.

[0120] Compared to the aforementioned embodiment in which the snap-fit ​​member 140 is snapped into the slots 131 at both ends of the rotating shaft 130, the snap-fit ​​member 140 in this embodiment may include a first snap-fit ​​member and a second snap-fit ​​member. One end of the rotating shaft 130 is integrally formed with the first snap-fit ​​member, and the other end of the rotating shaft 130 is provided with a slot 131. The other end of the rotating shaft 130 passes through the first through hole 1113 and the second through hole 1211. The rotational connection between the first connector 110 and the second connector 120 is realized by snapping the second snap-fit ​​member into the slot 131.

[0121] In other words, after one end of the rotating shaft 130 is integrally formed with the first snap-fit ​​component, the resulting structure can be similar to that of a screw, and the first snap-fit ​​component can be set as a stop at one end of the rotating shaft 130.

[0122] Of course, in other examples, after one end of the rotating shaft 130 is integrally formed with the first snap-fit ​​member, the resulting structure can also be a structure in which one end of the rotating shaft 130 protrudes from the first snap-fit ​​member, that is, the shaft head of one end of the rotating shaft 130 protrudes a certain distance from one side of the snap-fit ​​member 140. This application embodiment does not limit this.

[0123] In the above embodiment, the other end of the rotating shaft 130 is provided with a slot 131. One end of the rotating shaft 130 can be fixedly connected to the first snap-fit ​​member, and the other end of the rotating shaft 130 can pass through the first through hole 1113 and the second through hole 1211, and then be snapped into the slot 131 by the second snap-fit ​​member to realize the rotational connection between the first connecting member 110 and the second connecting member 120. Based on the above possible implementation, since one end of the rotating shaft 130 is fixedly connected to the first snap-fit ​​member, the reliability and stability of the connection between the first connecting member 110 and the second connecting member 120 can be further enhanced.

[0124] In other embodiments, one end of the rotating shaft 130 may be directly screw-shaped, and the other end of the rotating shaft 130 is provided with a slot 131. The other end of the rotating shaft 130 passes through the first through hole 1113 and the second through hole 1211, and the first connector 110 and the second connector 120 are rotated by using the snap-fit ​​member 140 to snap into the slot 131.

[0125] It should be noted that when the cavity wall of the wiring cavity 111 has a corresponding first through hole 1113 and the groove wall of the receiving groove 121 has a corresponding second through hole 1211, the specific way in which the rotating shaft 130 and the snap-fit ​​member 140 rotatably connect the first connector 110 and the second connector 120 in the corresponding first through hole 1113 (or the corresponding second through hole 1211) can be the same or different.

[0126] Taking the different specific ways in which the rotating shaft 130 and the snap-fit ​​member 140 are rotatably connected to the first connecting member 110 and the second connecting member 120 in the corresponding first through hole 1113 as an example, assuming that the corresponding first through holes 1113 are respectively called first through hole a and first through hole b, and the corresponding second through holes 1211 are respectively called second through hole a and second through hole b, where first through hole a and second through hole a correspond to each other, and first through hole b and second through hole b correspond to each other, then one end of a rotating shaft 130 can be fixedly connected to the first connecting member 110 and second connecting member 120. The other end of the rotating shaft 130 can be provided with a slot 131, and the other end of the rotating shaft 130 can pass through the first through hole a and the second through hole a, and be snapped into the slot 131 by the second snap-fit ​​component; the two ends of another rotating shaft 130 can be provided with slots 131 respectively, and one end of the rotating shaft 130 passes through the first through hole b and the second through hole b, and is snapped into the slots 131 at both ends of the rotating shaft 130 by the snap-fit ​​component 140, thereby realizing the rotational connection of the first connecting component 110 and the second connecting component 120.

[0127] In the above possible embodiments, see Figure 5 or Figure 6The first connector 110 may also include a protrusion 112, on which a fourth through hole 1121 may be provided. The fourth through hole 1121 may correspond to the first through hole 1113 on the wiring cavity 111. One end of the rotating shaft 130 may pass through the first through hole 1113, the fourth through hole 1121, and the second through hole 1211, and then be snapped onto both ends or one end of the rotating shaft 130 by the snap-fit ​​member 140, thereby realizing the rotational connection between the first connector 110 and the second connector 120.

[0128] It should be understood that the protrusion 112 can be an annular protrusion, and the position and size of the fourth through hole 1121 on the protrusion 112 can correspond to the position and size of the first through hole 1113.

[0129] In some embodiments, the protrusion 112 may also be integrally formed with the wiring cavity 111 to improve the stability and reliability of the structural design.

[0130] It is easy to understand that the number of protrusions 112 can be equal to the number of first through holes 1113, for example, both being two. The number of protrusions 112 can also be unequal to the number of first through holes 1113; for example, the number of protrusions 112 (e.g., four) is greater than the number of first through holes 1113 (e.g., two). This application embodiment does not limit this.

[0131] In other words, a protrusion 112 with a fourth through hole 1121 can be sandwiched between the first through hole 1113 and the second through hole 1211. This can increase the load-bearing capacity of the connection between the two connectors by using the protrusion 112, effectively preventing the connection from breaking or loosening due to stress concentration, significantly improving the strength and durability of the perforation position, and enhancing the connection strength and stability between the first connector 110 and the second connector 120.

[0132] In some embodiments, see Figure 5 The hinge assembly 100 may also include a washer 150, which can pass through the pivot 130 and is located between the first through hole 1113 and the second through hole 1211.

[0133] In the case where the first connector 110 also includes a protrusion 112, and a fourth through hole 1121 can be provided on the protrusion 112, the washer 150 can be disposed between the fourth through hole 1121 and the second through hole 1211. That is, the washer 150 can be sandwiched in the structure in which the first connector 110 and the second connector 120 are rotatably connected.

[0134] Alternatively, the washer 150 can be made of non-metallic materials such as rubber or plastic.

[0135] In other examples, the washer 150 may also be made of metal (e.g., steel, copper, aluminum, etc.) or composite material (e.g., metal and rubber composite, etc.), and this application embodiment does not limit this.

[0136] Of course, in addition to clamping the washer 150 between the first through hole 1113 and the second through hole 1211, the washer 150 can also be replaced with other connecting parts such as gaskets. Other connecting parts can be used to provide damping force during the rotation of the first connecting part 110 and the second connecting part 120.

[0137] Based on the above possible implementation methods, during the process of rotating the shaft 130 through the first through hole 1113 and the second through hole 1211 to rotatably connect the first connector 110 and the second connector 120, by adding a washer 150 between the first through hole 1113 and the second through hole 1211, without affecting the wiring space of the wiring cavity 111, the friction generated when rotating the first connector 110 and the second connector 120 provides damping force for the opening and closing of the temple 300 during the unfolding or folding process. This avoids the situation in actual applications where the temple 300 of the smart glasses 1 is quickly folded before it is worn on the user's head, thus improving the user experience.

[0138] In addition, the washer 150 is disposed between the first through hole 1113 and the second through hole 1211, which can also play a role in buffering and shock absorption during the unfolding or folding of the smart glasses 1, reducing wear between the first connector 110 and the second connector 120, increasing the wear resistance of the first connector 110 and the second connector 120, and extending the service life of the smart glasses 1.

[0139] In some embodiments, see Figures 5 to 7 The hinge assembly 100 may also include an elastic element 160. The second connector 120 may be provided with a first mounting groove 123. The bottom of the first mounting groove 123 may be the same as the groove wall of the receiving groove 121. One end of the elastic element 160 may be fixedly connected to the groove wall of the first mounting groove 123. A corresponding abutment post 113 may be provided on the wiring cavity 111. The abutment post 113 may be used to abut against the other end of the elastic element 160 during the unfolding of the temple 300.

[0140] In this embodiment of the application, one end of the elastic member 160 can be fixedly connected to the groove wall of the first mounting groove 123, while the other end of the elastic member 160 is not fixedly connected.

[0141] In some embodiments, one or more elastic elements 160 may be provided in the hinge assembly 100. Specifically, one end of one or more elastic elements 160 may be fixed to the groove wall of the first mounting groove 123, and the other end of one or more elastic elements 160 may not be fixed.

[0142] The elastic element 160 can be any one of the following: elastic band, spring, torsion spring, elastic sheet, or elastic post. This application does not limit the specific type of the elastic element 160 in its embodiments.

[0143] See Figure 7 The second connector 120 can be provided with two first mounting slots 123, which can be respectively located above and below the receiving slot 121, that is, the receiving slot 121 is sandwiched between the two first mounting slots 123. In this way, after the elastic member 160 is set in the first mounting slot 123, the setting of the elastic member 160 does not occupy the space of the wiring cavity 111, effectively increasing the wiring space of FPC and other devices.

[0144] See Figure 5 The first mounting groove 123 may include a second base plate 1231 and a second side plate 1232. That is, the second base plate 1231 and the second side plate 1232 can be combined to form the first mounting groove 123. (See also...) Figure 7 The groove wall with the second through hole 1211 in the receiving groove 121 can serve as the second bottom plate 1231 of the first mounting groove 123, that is, the groove wall of the receiving groove 121 can be the bottom of the first mounting groove 123.

[0145] In some embodiments, the second base plate 1231 may be annular. The second side plate 1232 may be arc-shaped overall.

[0146] It is easy to understand that the height and length along the arc edge of the second side plate 1232 can be flexibly set, and this application embodiment does not specifically limit this. In one example, the second side plate 1232 can also have inconsistent heights, for example, see Figure 8 The height of the side plate 1232 closest to the wiring trough 122 can be lower than the height of the side furthest from the wiring trough 122.

[0147] See Figure 5 or Figure 7 A second clearance groove 1233 is provided on the side of the first mounting groove 123 away from the wiring groove 122. The second clearance groove 1233 is arranged along the rotation direction between the first connector 110 and the second connector 120.

[0148] See Figure 6 The wiring cavity 111 is provided with an abutment post 113 for abutting against the other end of the elastic member 160 during the unfolding of the temple 300. The abutment post 113 may be in the shape of a Γ.

[0149] In some embodiments, a first clearance groove 1131 may be provided on the abutment post 113, and the specific design of the first clearance groove 1131 may be adapted to the specific design of the second clearance groove 1233.

[0150] During the rotation of the first connector 110 and the second connector 120, the abutment post 113 can slide along the side wall of the second clearance groove 1233. As the sliding distance increases, the end of the elastic member 160 that is not fixedly connected gradually abuts against the side wall of the abutment post 113. As the angle of the temple 300 unfolds, the extrusion force on the elastic member 160 increases.

[0151] Based on the above structural design, when the temple 300 is in the folded state, the elastic element 160 is not under force. In practical applications, the temple 300 can be folded by the rotational connection between the first connecting member 110 and the second connecting member 120. When the temple 300 changes from the folded state to the unfolded state, the temple 300 can drive the second connecting member 120 to rotate, so that the other end of the elastic element 160 can abut against the side wall of the abutment post 113. As the temple 300 gradually unfolds, the elastic element 160 is gradually compressed until the elastic element 160 is fully compressed, at which point the unfolding angle of the temple 300 can reach its maximum.

[0152] Optionally, the specific model and size of the elastic element 160 can be determined based on the unfolding angle of the temple 300 relative to the frame 200 in the smart glasses 1.

[0153] In some embodiments, the depth of the second clearance groove 1233 along the rotational direction between the first connector 110 and the second connector 120 can be adapted to the elastic force of the elastic member 160. This not only allows the elastic force of the elastic member 160 to limit the maximum unfolding angle of the temple 300, but also allows the abutment between the second clearance groove 1233 and the abutment post 113 to limit the maximum unfolding angle of the temple 300. That is, the maximum sliding distance of the abutment post 113 in the second clearance groove 1233 is used to limit the maximum unfolding angle of the temple 300.

[0154] In some embodiments, the depth of the second clearance groove 1233 may not be adapted to the elastic force of the elastic member 160. For example, the depth of the second clearance groove 1233 can be much greater than the sliding distance of the abutment post 113 within the second clearance groove 1233 when the elastic member 160 is fully compressed. Based on this, the second clearance groove 1233 can prevent interference between the abutment post 113 and the first mounting groove 123 during rotation of the first connector 110 and the second connector 120. It can also effectively reduce the weight of the hinge assembly 100 structure without affecting the normal rotation of the first connector 110 and the second connector 120, facilitating a thinner and lighter design for the smart glasses 1. Furthermore, in this case, the opening angle of the temple 300 can reach its maximum when the elastic member 160 is fully compressed, i.e., the opening angle of the temple 300 can be controlled by the elastic force of the elastic member 160.

[0155] In other examples, the depth of the second clearance groove 1233 can also be less than the sliding distance of the abutment post 113 in the second clearance groove 1233 when the elastic member 160 is fully compressed. In this way, the sliding distance of the abutment post 113 in the second clearance groove 1233 can be used to limit the maximum unfolding angle of the temple 300. This allows the unfolding and folding function of the temple 300 to be achieved without setting the elastic member 160.

[0156] Based on the above possible structural configuration, as the temple 300 of the smart glasses 1 unfolds, the elastic element 160 is compressed, and the temple 300 is folded by the elastic force of the elastic element 160 on the second connector 120. In this way, when the user wears the smart glasses 1, the temple 300 can also provide the smart glasses 1 with a clamping force on the user's head, so that the smart glasses 1 can effectively adapt to the usage needs of users with different head shapes or different head circumferences.

[0157] It is not difficult to understand that the design of the elastic element 160, with one end fixed and the other end not fixed, has a simple mechanical structure, occupies little space, and is both practical and convenient for the processing of the hinge assembly 100.

[0158] In some embodiments, see Figure 7 A hanging ear 1234 can also be provided on the groove wall of the first mounting groove 123. One end of the elastic member 160 passes through the hanging ear 1234 and is fixedly connected to the groove wall of the first mounting groove 123, while the other end of the elastic member 160 passes out from the other end of the hanging ear 1234.

[0159] In one example, the length of the loop 1234 can be less than or equal to the length of the elastic element 160 when it is fully compressed.

[0160] In some embodiments, one or more ear loops 1234 may be provided.

[0161] It is easy to understand that in this application, the number of hooks 1234 can be the same as the number of elastic elements 160. For example, assuming there are two hooks 1234 and two elastic elements 160, one end of each elastic element 160 can pass through a hook 1234 and be fixedly connected to the wall of the first mounting groove 123, and the other end of the elastic element 160 can pass through the other end of the corresponding hook 1234.

[0162] Of course, in other embodiments, the number of loops 1234 may differ from the number of elastic elements 160, and this application embodiment does not impose any limitation on this.

[0163] Based on the above possible implementation methods, the ear 1234 provided in the first mounting groove 123 can provide support for one end of the elastic member 160, which helps the elastic member 160 maintain a certain tightness and elasticity during the unfolding or folding of the smart glasses 1, and can also effectively prevent the elastic member 160 from deforming after being subjected to force by abutting the abutting post 113.

[0164] In some embodiments, see Figure 5 or Figure 9 The hinge assembly 100 may also include a housing 170, on which a first opening 171 may be provided. The housing 170 may surround the first connector 110, and the second connector 120 may extend through the first opening 171.

[0165] It should be understood that the first opening 171 provided on the housing 170 may include a first sub-opening 1711 and a second sub-opening 1712, the opening height of the second sub-opening 1712 (see...). Figure 9 h2) can be greater than the opening height of the first sub-opening 1711 (see h2). Figure 9 (h1 in the middle).

[0166] The opening height of the second sub-opening 1712 can be adapted to the total height of the second connector 120, and the opening height of the first sub-opening 1711 can correspond to the height of the wiring cavity 111 in the first connector 110. The total height of the second connector 120 can refer to the sum of the height of the receiving groove 121 and the height of the first mounting groove 123.

[0167] In one example, the opening height of the second sub-opening 1712 can be equal to the total height of the second connector 120, that is, the second connector 120 can just pass through the second sub-opening 1712 to exit the outer casing 170.

[0168] In other examples, the opening height of the second sub-opening 1712 may also be greater than or slightly greater than the total height of the second connector 120. This allows the height difference between the two to form a gap between the housing 170 and the second connector 120, facilitating heat dissipation and ventilation of devices such as FPCs installed in the wiring cavity 111.

[0169] In another example, the opening height of the first sub-opening 1711 can also be equal to the height of the wiring cavity 111. In this way, the first sub-opening 1711 can satisfy the rotation between the wiring cavity 111 and the second connector 120 during the unfolding or folding of the smart glasses 1, and is also beneficial to the sealing of the wiring cavity 111.

[0170] In other examples, the opening height of the first sub-opening 1711 can also be greater than or slightly greater than the height of the wiring cavity 111. Such a setting is beneficial for heat dissipation of devices such as FPCs in the wiring cavity 111.

[0171] Optionally, at least one sidewall of the housing 170 can be directly connected to the top of the shaft 130 by means of adhesive, welding or other methods.

[0172] In some embodiments, see Figure 5 The hinge assembly 100 may also include a fastener 180. At least one third through hole 172 may be provided on the side wall of the housing 170. One end of the pivot 130 may be provided with a second mounting groove 132. The fastener 180 may pass through at least one third through hole 172 and be disposed in the second mounting groove 132 to realize the detachable connection of the housing 170.

[0173] It should be understood that fastener 180, also known as housing 170 locking accessory, can be used to connect housing 170 to shaft 130 to achieve detachable connection of housing 170.

[0174] In some examples, fastener 180 may be a screw, rivet, or a device consisting of bolts and nuts, etc. This application does not limit this.

[0175] In this embodiment, the side wall of the outer shell 170 may be provided with a corresponding third through hole 172, and the end of the rotating shaft 130 away from the wiring cavity 111 may be provided with a second mounting groove 132. The fastener 180 may pass through the third through hole 172 and be disposed in the second mounting groove 132 for fixing the outer shell 170 and the rotating shaft 130 together.

[0176] It is not difficult to understand that the number and specific location of the third through hole 172 in the embodiments of this application can correspond to the number and location of the first through hole 1113, and / or the number and location of the second through hole 1211.

[0177] In one example, a groove 173 can also be provided on the outer side wall of the housing 170, and a third through hole 172 penetrates the bottom of the groove 173. This can effectively reduce the height of the hinge assembly 100 by lowering the height of the housing 170, thereby reducing the weight of the housing 170 and facilitating the miniaturization design of the hinge assembly 100.

[0178] Optionally, a gasket, washer 150 or other connecting parts may be provided between the third through hole 172 and the fastener 180 to enhance the reliability and stability of the connection between the housing 170 and the rotating shaft 130.

[0179] Based on the above possible implementation methods, regardless of whether the smart glasses 1 is in an unfolded or folded state, the FPC and other components in the corresponding area of ​​the hinge assembly 100 can be completely encapsulated in the hinge assembly 100, avoiding the situation where the FPC and other components are completely or partially exposed, effectively preventing the external environment from corroding the FPC and other components, further reducing the possibility of device damage, and improving the reliability of the connection of the smart glasses 1.

[0180] Furthermore, in the above possible embodiments, the pivot 130 can not only be used to fix the housing 170, but also to rotate between the first connector 110 and the second connector 120, which effectively reduces the space of the hinge assembly 100, and at the same time, effectively reduces the cost of structural design and manufacturing of the hinge assembly 100.

[0181] In some embodiments, the hinge assembly 100 may further include an angle detection assembly 190, which can be used to detect the opening angle between the frame 200 and the temple 300.

[0182] It should be understood that the opening angle between the frame 200 and the temple 300 can be found in [reference]. Figure 10 The angle α shown, the opening angle between the frame 200 and the temple 300, can also be used to indicate the opening angle between the first connector 110 and the second connector 120.

[0183] In one possible example, the angle detection component 190 may include a magnetic sensor 191 and a first magnet 192, wherein the magnetic sensor 191 may be disposed in the first connector 110 and the first magnet 192 may be disposed in the second connector 120; or, the magnetic sensor 191 may be disposed in the second connector 120 and the first magnet 192 may be disposed in the first connector 110.

[0184] It should be understood that the magnetic sensor 191 can be a linear magnetic sensor. The first magnet 192 can be any magnet, such as a magnet or a magnetic element made of magnetic material.

[0185] For details, see Figure 11 and Figure 12 The first connector 110 may include a third mounting groove 114, the bottom of which may have a second opening 1141, which may communicate with the first outlet 1112. The second connector 120 may include a fourth mounting groove 124, the opening direction of which may be opposite to the opening direction of the wiring groove 122. The magnetic sensor 191 may be disposed at the bottom of the third mounting groove 114, and the first magnet 192 may be disposed in the fourth mounting groove 124.

[0186] It should be understood that, see also Figure 8 and Figure 11 The third mounting groove 114 may include a first base plate 1142 and a first side plate 1143. One side of the first base plate 1142 may be fixedly connected to the wiring cavity 111, and the other side of the first base plate 1142 and the first side plate 1143 may be enclosed to form the groove of the third mounting groove 114. A second opening 1141 is provided on the first base plate 1142, and the first side plate 1143 may be inserted into the mirror frame 200 so that the first connector 110 and the mirror frame 200 are detachably connected.

[0187] Optionally, see Figure 10 An installation interface 210 corresponding to the slot of the third installation slot 114 can be provided on the frame 200. The first side plate 1143 of the third installation slot 114 can be inserted into the installation interface 210 to realize the detachable connection between the frame 200 and the first connector 110.

[0188] In some embodiments, adhesive or similar substances may be applied to the outer side wall of the first side plate 1143 or the inner side wall of the mounting interface 210 to install the first side plate 1143 of the third mounting groove 114 in the mounting interface 210, thereby achieving a fixed connection between the mirror frame 200 and the first connector 110.

[0189] Of course, in other examples, the connection between the frame 200 and the first connector 110 can also be achieved by means of devices such as screws, and this application embodiment does not limit this.

[0190] In some embodiments, see Figure 11 The setting height H2 of the first base plate 1142 can be the sum of the setting height of the receiving groove 121 in the second connector 120 and the setting height of at least one first mounting groove 123.

[0191] Of course, in other embodiments, the setting height H2 of the first base plate 1142 can also be adapted to the size of the mounting interface 210 in the frame 200. This application embodiment does not limit this.

[0192] Based on the above embodiments, the connection between the second opening 1141 and the first outlet 1112 is realized through the connection between the third mounting groove 114 and the wiring cavity 111. FPC and other devices entering the wiring cavity 111 can enter the frame 200 from the first outlet 1112 and the second opening 1141, effectively realizing the wire-passing hinge assembly 100 between the temple 300 and the FPC and other devices in the frame 200.

[0193] Alternatively, the third mounting slot 114 can also be integrally formed with the wiring cavity 111.

[0194] See Figure 12The fourth mounting groove 124 can be disposed on the side of the second connector 120 away from the wiring groove 122. In this embodiment, the wiring groove 122, the receiving groove 121 and the fourth mounting groove 124 can be disposed on different side walls of the second connector 120 respectively.

[0195] This arrangement not only does not affect the rotational connection between the first connector 110 and the second connector 120, but also, with the magnetic sensor 191 positioned at the bottom of the third mounting slot 114 and the first magnet 192 positioned in the fourth mounting slot 124, the distance between the magnetic sensor 191 and the first magnet 192 is closest when the smart glasses 1 is in the unfolded state; and the distance between the magnetic sensor 191 and the first magnet 192 is farthest when the smart glasses 1 is in the folded state. This facilitates determining the opening angle between the frame 200 and the temple 300 by using the distance between the magnetic sensor 191 and the first magnet 192.

[0196] Based on the above possible implementation methods, the positional relationship between the magnetic sensor 191 and the first magnet 192 can be changed by rotating the temple 300, thereby effectively detecting the opening angle of the temple 300 in the smart glasses 1. This facilitates the expansion of the functions of the smart glasses 1. For example, the state of the smart glasses 1 can be determined based on the opening angle of the temple 300. Specifically, if the opening angle of the temple 300 is 60° to 110°, it can be determined that the user is using the smart glasses 1, and the smart glasses 1 can be kept in working state so that the user can use the smart glasses 1 immediately. Conversely, if the opening angle of the temple 300 is 0° to 15°, it can be determined that the user is not using the smart glasses 1, and the smart glasses 1 can be kept in sleep state to save energy and extend the continuous use time of the smart glasses 1.

[0197] In the actual structural design, the magnetic sensor 191 can also be placed in the fourth mounting slot 124, and the first magnet 192 can be placed at the bottom of the third mounting slot 114. This arrangement is not shown in the figure.

[0198] Optionally, a mounting through hole 125 may also be provided on the second connector 120, which can be used for a detachable connection between the second connector 120 and the temple 300.

[0199] It should be understood that the mounting through hole 125 can communicate with the bottom of the receiving groove 121. Screws or other devices can be used to pass through the mounting through hole 125 to securely connect the second connector 120 and the temple 300.

[0200] Alternatively, the second connector 120 can also be integrally formed with the temple 300.

[0201] Based on the above possible implementation methods, the connection between the second connector 120 and the temple 300 can be achieved without affecting the rotatable connection between the second connector 120 and the first connector 110. This effectively avoids the space occupied by the need to set up a corresponding structure to connect with the temple 300, which is conducive to the thin and light design of the hinge assembly 100. At the same time, it also effectively reduces the cost of structural design and manufacturing of the hinge assembly 100.

[0202] Optionally, the angle detection component 190 may also include rotating and fixed electrodes, a gyroscope and an accelerometer, etc.

[0203] For example, taking the angle detection component 190, which includes a rotating electrode and a fixed electrode, as an example, the rotating electrode can be an arc-shaped capacitor plate, and the fixed electrode can be an array of plates corresponding to the arc-shaped capacitor plate. The plate array can be set on the first connector 110, and the arc-shaped capacitor plate can be set on the second connector 120. During the rotation of the first connector 110 and the second connector 120, the overlapping area between the two plates will change as the first connector 110 and the second connector 120 rotate, thereby causing the capacitance value to change. In practical applications, the opening and closing angle between the first connector 110 and the second connector 120 can be calculated by using the capacitance and angle calibration curve.

[0204] For example, a gyroscope can be installed on the first connector 110 and an accelerometer can be installed on the second connector 120. During the rotation of the first connector 110 and the second connector 120, the angle difference can be obtained by integrating the relative angular velocity and attitude analysis, thereby obtaining the opening and closing angle between the first connector 110 and the second connector 120.

[0205] The hinge assembly 100 provided in this application embodiment can also be applied to other electronic devices, such as laptops, foldable screen phones, cameras, robots, smartwatches, etc.

[0206] As an example, and not a limitation, a laptop computer can achieve a rotating connection between the display and the host; a foldable phone uses it to achieve rotation between the foldable screens; a camera uses the hinge assembly 100 to achieve a rotating connection between the lens module and the body; a robot uses the hinge assembly 100 to achieve rotation between different joints; and a smartwatch uses it to achieve a rotating connection between the strap and the watch body.

[0207] Furthermore, the hinge assembly 100 provided in this application embodiment can also be applied to devices such as medical devices (e.g., endoscopes, wearable monitoring instruments, etc.), drones, and vehicle screens and rearview mirrors in transportation vehicles such as automobiles. The hinge assembly 100 provided in this application embodiment can meet the rotational connection requirements between different parts of various devices. This application embodiment does not limit the specific types of electronic devices to which the hinge assembly 100 can be applied.

[0208] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
