Description

Technical Field

[0001] The present invention relates to the field of wearable devices, and in particular to a hinge module and glasses. Background Art

[0002] The temples and frames of AR smart glasses are generally connected by a hinge module, which allows the glasses to be folded for easy storage. However, traditional glasses require a continuous outward force on the temples to fully open them. If the user withdraws the force midway, the glasses often fail to fully open. In addition, the temples and frames contain components such as optical engines, circuit boards, batteries, and speakers, which cannot deform. The clamping force during wear is mainly provided by the deformation of the temple ends, but the deformation is limited. Therefore, when worn by users with different head sizes, the glasses may appear loose or tight, affecting the user's wearing comfort. Summary of the Invention

[0003] The main purpose of the present invention is to propose a hinge module, which aims to enable glasses to automatically open within a certain range, ensuring that the temples can be opened into place; at the same time, it can also adaptively adjust the wearing tightness according to the user's head size, thereby improving the user's wearing comfort.

[0010] In one embodiment, the outward-turned elastic member includes a main body section and two elastic arms. The main body section is annular with one side open. The two elastic arms are respectively arranged at both ends of the main body section and bent outward relative to the main body section. One of the elastic arms is fixed to the first hinge joint, and the other elastic arm is used to cooperate with the trigger member.

[0011] In one embodiment, the first hinge joint includes a fixed shell and a first rotating arm provided on one side of the fixed shell, the fixed shell is provided with a accommodating cavity and a through hole connected to the accommodating cavity, the second hinge joint includes a rotating body and a second rotating arm provided on one side of the rotating body, the rotating body is accommodated in the accommodating cavity, the second rotating arm extends from the through hole, the rotating body and the fixed shell are rotatably connected via a rotating shaft, the slingshot elastic member and the outward-turning elastic member are both installed on the fixed shell, and the trigger member is connected to the rotating body.

[0012] In one embodiment, the fixed shell is provided with an arc-shaped track groove, and the trigger member is slidably matched with the track groove. When the second hinge joint is flipped outward to a preset angle relative to the first hinge joint, the trigger member is limitedly abutted against one end of the track groove.

[0013] In one embodiment, the fixed shell includes a bottom wall and a side wall extending to one side from the periphery of the bottom wall, the bottom wall and the side wall enclose the accommodating cavity, the through hole is provided on the side wall, the track groove is provided on the bottom wall, the rotating body and the bottom wall are correspondingly provided with an axial hole for the rotating shaft to pass through, the trigger member is connected to a side of the rotating body close to the bottom wall, the trigger member passes through the bottom wall via the track groove, and the slingshot elastic member and the outward-turned elastic member are both fixed on the side of the bottom wall away from the accommodating cavity.

[0014] In one embodiment, the hinge module further includes a feedback component connected to the second hinge joint, and the feedback component is used to issue a feedback prompt when the second hinge joint is opened or folded into place.

[0015] In one embodiment, the feedback assembly includes a mounting plate and a feedback elastic member, the mounting plate is fixed to the second hinge joint, the feedback elastic member includes a fixing portion, a feedback portion and a connecting arm connected between the fixing portion and the feedback portion, the fixing portion is fixed to the mounting plate, the first hinge joint is provided with an opening hole, during the opening process of the second hinge joint, the feedback portion is squeezed and fitted with the first hinge joint, when the second hinge joint is opened into place, the feedback portion is accommodated in the opening hole and generates sound and / or vibration feedback prompts during the process of restoring deformation.

[0016] In one embodiment, the first hinge joint further includes a folding-into-place hole, and during the folding process of the second hinge joint, the feedback portion is squeezed and fitted with the first hinge joint.

[0019] The technical solution of the present invention incorporates a slingshot mechanism between a first hinge joint and a second hinge joint. When the second hinge joint rotates at a greater than a predetermined angle relative to the first, the slingshot mechanism causes the second hinge joint to move toward an open position. When this hinge module is applied to eyeglasses, the first hinge joint connects to the frame, and the second hinge joint connects to the temples. The slingshot mechanism then allows the glasses to automatically open within a certain range, ensuring the temples fully open. When an eversion force is applied to the temple, the eversion force is transmitted to the second hinge joint, causing the second hinge joint to flip outward relative to the first hinge joint, so that the temple has a certain amount of eversion space to adapt to the size of the user's head; during the eversion process, the eversion elastic member deforms, and the elastic force generated by the eversion elastic member causes the temple to have a tendency to flip back to the open state, thereby allowing the temple to clamp the user's head and maintain wearing stability; when the glasses are removed, the eversion force is completely removed, and the eversion elastic member recovers its deformation, allowing the temple to automatically flip inward and return to the open state. The hinge module of this technical solution can enable the glasses to achieve automatic folding function within a certain range, ensuring that the temples can be folded into place; at the same time, it can also adaptively adjust the wearing tightness according to the user's head size to improve the user's wearing comfort.

[0038] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The present invention provides a hinge module 100. The hinge module 100 can be used for a rotational connection between two components. The following mainly uses the hinge module 100 applied to glasses as an example for description. It is understandable that the hinge module 100 can also be applied to other products that require folding and everting functions.

[0043] Please refer to Figure 1 In one embodiment of the present invention, the hinge module 100 includes a first hinge joint 10, a second hinge joint 20, a slingshot mechanism, and an outward-turning elastic member 40. The second hinge joint is rotatably connected to the first hinge joint, and the second hinge joint has an open state and a folded state relative to the first hinge joint; the slingshot mechanism is provided between the first hinge joint and the second hinge joint, and when the rotation angle of the second hinge joint relative to the first hinge joint is greater than a preset rotation angle, the slingshot mechanism is used to cause the second hinge joint to have a tendency to move toward the open state; the outward-turning elastic member is provided between the first hinge joint and the second hinge joint, and when the second hinge joint flips outward from the open state, the outward-turning elastic member is used to cause the second hinge joint to have a tendency to move toward the open state.

[0044] Specifically, if Figure 6As shown, when the hinge module 100 is applied to glasses, the first hinge joint 10 can be connected to the frame 200, and the second hinge joint 20 can be connected to the temple 300. The second hinge joint 20 and the first hinge joint 10 are rotatably connected, thereby allowing the temple 300 to rotate relative to the frame 200 between a folded state and an open state. For ease of explanation, in this embodiment, the folded state is taken as the initial state. Please refer to the embodiment for details. Figure 9 In the folded state, the first hinge joint 10 and the second hinge joint 20 are substantially perpendicular to each other. At this time, the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 is 0°, and the temple 300 is folded to 0° relative to the frame 200. In the open state, the first hinge joint 10 and the second hinge joint 20 are substantially in the same straight line. At this time, the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 is 90°, and the temple 300 is opened to 90° relative to the frame 200. That is, between the folded state and the open state, the rotation angle range of the second hinge joint 20 relative to the first hinge joint 10 is 0° to 90°. It should be noted that Figures 5 to 14 The frame 200 and the temples 300 are simplified. In practice, in the open state, the extension direction of the frame 200 is perpendicular to the extension direction of the temples 300. At this time, the temples 300 are opened 90° relative to the frame 200.

[0045] A slingshot mechanism is provided between the first hinge joint 10 and the second hinge joint 20. During the process of switching the second hinge joint 20 from the folded state to the opened state, the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 gradually increases from 0° to 90°. When the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 is greater than the preset rotation angle, the slingshot mechanism can generate a force on the second hinge joint 20 so that the second hinge joint has a tendency to move toward the opened state. For example, the preset rotation angle is 45°. During the process of opening the second hinge joint 20 relative to the first hinge joint 10, the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 gradually increases from 0°. When the rotation angle is greater than 45°, the slingshot mechanism provides a force to the second hinge joint 20 to move toward the opened state. At this time, when the external force is removed, the slingshot mechanism will push the second hinge joint 20 to automatically move to the opened state, and then the second hinge joint 20 can drive the temple 300 to automatically open into place. It should be noted that the preset rotation angle can be set as needed and is not limited to 45°.

[0046] In addition, to enable the glasses to adaptively adjust the tightness of the glasses according to the user's head size and improve wearing comfort, the hinge module 100 also includes an outward-turning elastic member 40 disposed between the first hinge joint 10 and the second hinge joint 20. The second hinge joint 20 can be turned outward relative to the first hinge joint 10 from the open state under the action of an external force. When the second hinge joint 20 turns outward, the outward-turning elastic member 40 is used to cause the second hinge joint 20 to move toward the open state.

[0047] The technical solution of the present invention employs a slingshot mechanism between a first hinge joint 10 and a second hinge joint 20. When the second hinge joint 20 rotates relative to the first hinge joint 10 at a greater than a predetermined angle, the slingshot mechanism causes the second hinge joint 20 to move toward an open position. When the hinge module 100 is applied to eyeglasses, the first hinge joint 10 connects to the frame 200, and the second hinge joint 20 connects to the temple 300. The slingshot mechanism then allows the glasses to automatically open within a certain range, ensuring that the temple 300 fully opens. When an eversion force is applied to the temple 300, the eversion force is transmitted to the second hinge joint 20, causing the second hinge joint 20 to flip outward relative to the first hinge joint 10, so that the temple 300 can have a certain eversion space to adapt to the user's head size; during the eversion process, the eversion elastic member 40 is deformed, and the elastic force generated by the eversion elastic member 40 causes the temple 300 to have a tendency to flip back to the open state, thereby enabling the temple 300 to clamp the user's head and maintain wearing stability; when the glasses are removed, the eversion force is completely removed, and the eversion elastic member 40 recovers its deformation, allowing the temple 300 to automatically flip inward and return to the open state. The hinge module 100 of this technical solution can enable the glasses to realize the automatic folding function within a certain range, ensuring that the temple can be folded into place; at the same time, it can also adaptively adjust the wearing tightness according to the user's head size to improve the user's wearing comfort.

[0048] Please refer to Figure 10 In one embodiment, the slingshot mechanism includes a slingshot elastic member 30 and a trigger member 50. The slingshot elastic member 30 and the outward-turning elastic member 40 are both installed on the first hinge joint 10. The trigger member 50 is connected to the second hinge joint 20 and can move with the second hinge joint 20. During the movement of the trigger member 50, it can cooperate with the slingshot elastic member 30 or the outward-turning elastic member 40 so that the second hinge joint 20 has a tendency to move toward the open state.

[0049] Specifically, the second hinge joint 20 can drive the trigger member 50 to move during its rotation relative to the first hinge joint 10. When the second hinge joint 20 switches between the folded state and the open state, the trigger member 50 moves along with the second hinge joint 20. When the rotation angle of the second hinge joint 20 relative to the first hinge joint 10 is greater than a predetermined rotation angle, the trigger member 50 can exert a certain force on the slingshot elastic member 30, which in turn exerts an elastic force in the opposite direction on the trigger member 50. When the external force is removed, the slingshot elastic member 30 recovers its deformation to push the trigger member 50 to move, thereby moving the second hinge joint 20 to the open state. When the second hinge joint 20 flips outward from the open state under the action of an external force, the trigger member 50 can act on the outward-turning elastic member 40. When the external force is removed, the outward-turning elastic member 40 recovers its deformation and exerts a force on the trigger member 50, thereby driving the second hinge joint 20 back to the open state. When the second hinge joint 20 is in the open state, the slingshot elastic member 30 and the outward-turning elastic member 40 act together to keep the second hinge joint 20 in the open state without shaking left and right.

[0050] like Figure 12 As shown, in one embodiment, the slingshot elastic member 30 includes a first elastic section 31 and a second elastic section 32, and one end of the first elastic section 31 and the second elastic section 32 are connected, and the other ends of the first elastic section 31 and the second elastic section 32 extend toward the same side and away from each other; when the angle between the second hinge joint 20 and the first hinge joint 10 is greater than the preset rotation angle, the first elastic section 31 acts on the trigger member 50 so that the second hinge joint 20 has a tendency to move toward the open state; when the angle between the second hinge joint 20 and the first hinge joint 10 is less than the preset rotation angle, the second elastic section 32 acts on the trigger member 50 so that the second hinge joint 20 has a tendency to move toward the folded state.

[0051] Specifically, in this embodiment, the slingshot elastic member 30 is generally in a "V"-shaped structure, and the opening between the separated ends of the first elastic section 31 and the second elastic section 32 faces the rotation center of the second hinge joint 20 (i.e., the rotation axis 70). Figure 10 As shown, during the movement of the temple 300 from the open state to the folded state, an inward force F is applied to the temple 300. 叠 , the temple 300 drives the second hinge joint 20 to rotate clockwise. During this process, the trigger 50 moves along the slingshot elastic member 30 and applies pressure to the slingshot elastic member 30. When the trigger 50 moves along the first elastic section 31, the first elastic section 31 generates an elastic force on the trigger 50 and the F 叠In the opposite direction, if the external force is removed, the first elastic section 31 will push the second hinge joint 20 and the temple 300 back to the open state. 叠 When the connection position of the first elastic section 31 and the second elastic section 32 is reached, F 叠 is greater than the maximum elastic force of the slingshot elastic member 30 on the trigger member 50, the slingshot elastic member 30 is compressed to the maximum deformation; when the trigger member 50 moves to the second elastic section 32, the elastic force generated by the second elastic section 32 on the trigger member 50 is equal to F 叠 In the same direction, the second elastic member will push the second hinge joint 20 to rotate quickly in the clockwise direction to the folded position, thereby quickly folding the temple 300 into place. Conversely, the process of the temple 300 moving from the folded state to the open state is similar and will not be repeated here.

[0052] Furthermore, the outward-turned elastic member 40 includes a main body section 41 and two elastic arms 42. The main body section 41 is annularly arranged with one side open. The two elastic arms 42 are respectively arranged at both ends of the main body section 41 and bent outward relative to the main body section 41. One of the elastic arms 42 is fixed to the first hinge joint 10, and the other elastic arm 42 is used to cooperate with the trigger member 50.

[0053] Specifically, if Figure 10 As shown, in the open state, the pre-stressed slingshot elastic member 30 exerts an elastic force F1 on the trigger member 50, pushing the trigger member 50 counterclockwise. At the same time, an initial preload force F2 is applied to the end of the elastic arm 42 of the outward-turning elastic member 40. F2 is designed to be greater than F1. When the trigger member 50 rotates counterclockwise until it just contacts the outward-turning elastic member 40, it stops rotating, keeping the second hinge joint 20 in the open state relative to the first hinge joint 10. Figure 11 As shown, when the eversion force acts on the temple 300, the eversion force drives the second hinge joint 20 to flip outward from the open state, and the second hinge joint 20 drives the trigger member 50 to move together. The trigger member 50 generates a force on the eversion elastic member 40. When the force generated by the trigger member 50 on the eversion elastic member 40 is greater than the initial preload force F2 of the elastic arm 42, the trigger member 50 pushes the elastic arm 42 to deform and rotate counterclockwise. When the eversion force is removed, the elastic arm 42 recovers its deformation and generates a reverse elastic force on the trigger member 50, so that the second hinge joint 20 moves in the reverse direction and resets.

[0054] Please refer to Figure 2 and Figure 3In one embodiment, the first hinge joint 10 includes a fixed shell 11 and a first rotating arm 12 provided on one side of the fixed shell 11, the fixed shell 11 is provided with a accommodating cavity 111 and a through hole 112 communicating with the accommodating cavity 111, the second hinge joint 20 includes a rotating body 21 and a second rotating arm 22 provided on one side of the rotating body 21, the rotating body 21 is accommodated in the accommodating cavity 111, the second rotating arm 22 extends from the through hole 112, the rotating body 21 and the fixed shell 11 are rotatably connected via a rotating shaft 70, the slingshot elastic member 30 and the outward-turning elastic member 40 are both installed on the fixed shell 11, and the trigger member 50 is connected to the rotating body 21.

[0055] Specifically, the first hinge joint 10 is connected to the first component (e.g., the frame 200) via the first rotating arm 12, and the second hinge joint 20 is connected to the second component (e.g., the temple 300) via the second rotating arm 22. When the rotating body 21 rotates relative to the fixed shell 11, the second rotating arm 22 is driven to rotate relative to the first rotating arm 12. In the open state, the first rotating arm 12 and the second rotating arm 22 are respectively located on opposite sides of the fixed shell 11 and are generally in the same straight line; in the folded state, the first rotating arm 12 and the second rotating arm 22 are generally perpendicular. Figure 6 and Figure 7 As shown, when the hinge module 100 is applied to glasses, the first rotating arm 12 can be inserted into the frame 200 and fixed, and the second rotating arm 22 can be inserted into the temple 300 and fixed, so that the overall appearance of the glasses is more consistent. In order to further enhance the visual effect, the fixed shell 11 and the rotating body 21 can be set into a regular cylinder. Figure 5 and Figure 6 As shown, when the glasses are in the open state, they appear to be a single entity when viewed from both the outside and from above. Only when viewed from the inside can a portion of the rotating body 21 be seen, and this portion of the rotating body 21 is a regular, integrated structure. When the glasses are in the folded state, they appear to be a single entity when viewed from both the inside and from above. Only when viewed from the outside can a portion of the rotating body 21 be seen, and this portion of the rotating body 21 is a regular, integrated structure. When the glasses are in the everted state (i.e., when worn), they appear to be a single entity when viewed from both the outside and as a whole. Only when viewed from the inside can a portion of the rotating body 21 be seen, and this portion of the rotating body 21 is a regular, integrated structure.

[0056] Further, if Figure 2 and Figure 11As shown, the fixed housing 11 is provided with an arcuate track groove 114. The trigger member 50 slidably engages with the track groove 114. When the second hinge joint 20 is tilted outward to a predetermined angle relative to the first hinge joint 10, the trigger member 50 engages with one end of the track groove 114. Specifically, when the second hinge joint 20 is tilted outward to a predetermined angle, the end of the track groove 114 engages with the trigger member 50, stopping the second hinge joint 20 from everting outward. Furthermore, the sliding engagement between the trigger member 50 and the track groove 114 provides a certain degree of guidance for the rotation of the second hinge joint 20.

[0057] Further, if Figure 2 and Figure 3 As shown, the fixed housing 11 includes a bottom wall and a side wall extending from the periphery of the bottom wall to one side. The bottom wall and the side wall together form the accommodating cavity 111. The through hole 112 is provided in the side wall, and the track groove 114 is provided in the bottom wall. The rotating body 21 and the bottom wall are respectively provided with an axial hole for the rotation shaft 70 to pass through. The trigger member 50 is connected to the side of the rotating body 21 near the bottom wall. The trigger member 50 passes through the bottom wall via the track groove 114. The slingshot elastic member 30 and the outward-turning elastic member 40 are both fixed to the side of the bottom wall away from the accommodating cavity 111. During assembly, the rotating body 21 is installed in the accommodating cavity 111 and fixedly connected to the bottom wall via the rotation shaft 70. The rotating body 21 is rotatably connected to the rotation shaft 70. The rotation shaft 70 can be specifically a rotation shaft 70 screw. The trigger member 50 can be specifically a pin threadedly connected to the rotating body 21, extending downward through the track groove 114. To ensure a secure connection, the trigger member 50 and the rotating body 21 can be reinforced by spot welding. The slingshot elastic member 30 and the outward-turning elastic member 40 are both fixed to the side of the bottom wall away from the accommodating cavity 111, capable of cooperating with the trigger member 50.

[0058] Further, if Figure 3 As shown, the fixed housing 11 is provided with a mounting groove 115 on a side of the bottom wall away from the accommodating cavity 111. The slingshot elastic member 30 and the outward-turning elastic member 40 are both received within the mounting groove 115. The mounting groove 115 forms a first opening on a side away from the bottom wall. The first hinge joint 10 also includes a first end cap 13 covering the first opening. The slingshot elastic member 30 and the outward-turning elastic member 40 are both received within the mounting groove 115, and the first end cap 13 covers the first opening, thereby effectively protecting and concealing the slingshot elastic member 30 and the outward-turning elastic member 40.

[0059] Furthermore, the accommodating cavity 111 has a second opening formed on a side away from the bottom wall, and the first hinge joint 10 also includes a second end cap 14 covering the second opening. The second opening facilitates the installation of other components (such as the feedback assembly 60 in the embodiment described below) into the accommodating cavity 111, and the second end cap 14 closes the second opening, thereby effectively protecting and concealing the feedback assembly 60.

[0060] Please refer to Figure 3 In one embodiment, the hinge module 100 further includes a feedback component 60 connected to the second hinge joint 20, and the feedback component 60 is used to issue a feedback prompt when the second hinge joint 20 is opened or folded into place. By setting the feedback component 60, when the second hinge joint 20 is opened or folded into place, the feedback component 60 issues a feedback prompt, so that the user can clearly understand whether the glasses are fully opened or fully folded. Among them, the feedback component 60 can adopt a purely mechanical structure to achieve in-place detection, and can also adopt a sensor to achieve in-place detection. The feedback prompts issued by the feedback component 60 include but are not limited to sound feedback prompts, vibration feedback prompts or light feedback prompts.

[0061] Please refer to Figure 2 、 Figure 3 and Figure 13 In one embodiment, the feedback assembly 60 includes a mounting plate 61 and a feedback elastic member 62, the mounting plate 61 is fixed to the second hinge joint 20, the feedback elastic member 62 includes a fixing portion 621, a feedback portion 622 and a connecting arm 623 connected between the fixing portion 621 and the feedback portion 622, the fixing portion 621 is fixed to the mounting plate 61, the first hinge joint 10 is provided with an opening hole 101, during the opening process of the second hinge joint 20, the feedback portion 622 is squeezed and fitted with the first hinge joint 10, when the second hinge joint 20 is opened to the position, the feedback portion 622 is accommodated in the positioning hole and generates sound and / or vibration feedback prompts during the process of restoring deformation.

[0062] Specifically, the mounting plate 61 can be secured to the second hinge joint 20 via first fasteners 63. For example, the mounting plate 61 is secured to the top of the rotating body 21 of the second hinge joint 20 via three first fasteners 63. The feedback elastic member 62 includes a fixing portion 621, a feedback portion 622, and a connecting arm 623. The fixing portion 621 is annular and has a central hole. The mounting plate 61 has a fixing hole corresponding to the central hole of the fixing portion 621. The fixing portion 621 can be connected to the fixing hole of the mounting plate 61 via second fasteners 64. The connecting arm 623 is generally V-shaped, with one end of the connecting arm 623 connected to the fixing portion 621 and the other end connected to the feedback portion 622. The feedback portion 622 is an arc-shaped structure that protrudes toward the inner wall surface of the fixed housing 11 of the first hinge joint 10. The first fasteners 63 and the second fasteners 64 can specifically be screws. Optionally, the feedback elastic member 62 is formed by bending a single elastic strip. In order to ensure the installation stability of the feedback elastic member 62, a limiting rib that is engaged with the connecting arm 623 is also provided on the mounting plate 61. The inner wall surface of the fixed shell 11 of the first hinge joint 10 is provided with an opening hole 101, and the opening hole 101 is an arc-shaped hole adapted to the feedback part 622. During the opening process of the second hinge joint 20, the feedback part 622 is squeezed and fitted with the inner wall surface of the fixed shell 11 to be compressed. When the second hinge joint 20 is opened to the full position, the feedback part 622 is accommodated in the opening hole 101 and restores its deformation. During the process of restoring the deformation, the feedback part 622 collides with the inner wall surface of the opening hole to produce a sound and vibration effect similar to "pop", thereby prompting the user that the glasses have been opened to the full position.

[0063] Furthermore, the first hinge joint 10 also includes a folding-into-place hole. During the folding process of the second hinge joint 20, the feedback part 622 is squeezed and fitted with the first hinge joint 10. When the second hinge joint 20 is folded into place, the feedback part 622 is accommodated in the folding-into-place hole and generates sound and / or vibration feedback prompts during the process of restoring the deformation.

[0064] Specifically, the folding hole is an arc-shaped hole that matches the feedback portion 622. During the folding process of the second hinge joint 20, the feedback portion 622 is squeezed and fitted with the inner wall surface of the fixed shell 11, causing compression. When the second hinge joint 20 is folded into place, the feedback portion 622 is accommodated in the folding hole 101 and recovers its shape. During the recovery process, the feedback portion 622 collides with the inner wall surface of the hole, producing a "snapping" sound and vibration effect, thereby notifying the user that the glasses have been folded into place.

[0065] Furthermore, the second hinge joint 20 has a first folding position and a second folding position, and the folding-in-place hole includes a first folding-in-place hole 102 and a second folding-in-place hole 103. When the second hinge joint 20 is in the first folding position, the feedback part 622 is accommodated in the first folding-in-place hole 102, and when the second hinge joint 20 is in the second folding position, the feedback part 622 is accommodated in the second folding-in-place hole 103.

[0066] Specifically, the first folding-in-place hole 102 and the second folding-in-place hole 103 are arranged at intervals along the circumference of the first hinge joint 10. When the second hinge joint 20 moves from the open state to the folded state, the feedback elastic member 62 will rotate along with the second hinge joint 20, and then the feedback portion 622 of the feedback elastic member 62 will move along the circumference of the first hinge joint 10. When rotated to the fully folded state (that is, reaching the second folded position), the feedback portion 622 is accommodated in the second folding-in-place hole 103 and restores the deformation to emit a sound and vibration prompt. When the hinge module 100 is applied to glasses, considering that the glasses usually have two temples 300, if one of the temples 300 is already in the fully folded state, the other temple 300 can only move to the first folded position. At this time, the feedback portion 622 is accommodated in the first folding-in-place hole 102 and restores the deformation to emit a sound and vibration prompt.

[0067] In order to make the hinge module 100 more functional and more integrated, in one embodiment, the hinge module 100 also includes a functional module 80 installed on the first hinge joint 10, and the first hinge joint 10 is also provided with a functional area 141 corresponding to the functional module 80, and the functional area 141 is used to control the functional module 80 and / or to display the information output by the functional module 80.

[0068] Specifically, in this embodiment, the functional module 80 is disposed on a side of the second end cover 14 of the first hinge joint 10 near the accommodating cavity 111. The second end cover 14 is provided with a functional area 141 corresponding to the functional module 80. The functional area 141 is used to control the functional module 80 and / or to display information output by the functional module 80. For example, the functional area 141 on the second end cover 14 can be used to implement functions such as volume adjustment, touch switch, or battery indicator light.

[0069] Furthermore, the functional module 80 includes an adhesive portion 81 and a multifunctional flexible circuit board 82. The multifunctional flexible circuit board 82 is attached to one side of the second end cap 14 via the adhesive portion 81. The side wall is provided with a through-hole 113 through which the end of the multifunctional flexible circuit board 82 passes. During assembly, the multifunctional flexible circuit board 82 is bonded to the second end cap 14 via the adhesive portion 81. The end of the multifunctional flexible circuit board 82 is then passed through the through-hole 113 and placed within the frame 200. The multifunctional flexible circuit board 82 is secured to the second end cap 14. When the second hinge joint 20 rotates, the multifunctional flexible circuit board 82 does not rotate, allowing it to function normally.

[0070] In order to be better applied to smart glasses, such as Figure 4 As shown, further, the first hinge joint 10 and the second hinge joint 20 are both hollow and have a through cavity that is interconnected. The two ends of the through cavity respectively pass through the first rotating arm 12 and the second rotating arm 22. The hinge module 100 also includes a flexible circuit board 90 that is inserted into the through cavity. After the flexible circuit board 90 of the smart glasses passes through the first hinge joint 10 and the second hinge joint 20, the two ends of the flexible circuit board 90 can be respectively accommodated in the frame 200 and the temple 300, making the overall structure more compact. Specifically, as Figure 3 As shown, the second hinge joint 20 is provided with an opening communicating with the through cavity, a cover plate 23 is fixed at the opening, and the cover plate 23 is provided with a connecting hole connected to the trigger member 50 and an axial hole for the rotating shaft 70 to pass through.

[0071] Please refer to Figures 5 to 7 The present invention further provides a pair of glasses comprising a frame 200, temples 300, and a hinge module 100. The hinge module 100 connects the frame 200 to the temples 300. The specific structure of the hinge module 100 is similar to that of the above embodiments. Since the present glasses adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
