Description

Hinge module and smart glasses

[0001] This application claims priority to Chinese Patent Application No. 202410844229.7, filed on June 26, 2024, entitled "Hinge Module and Smart Glasses", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of head-mounted display technology, and in particular to a hinge module and smart glasses using the hinge module. Background Technology

[0003] Currently, the frames and temples of smart glasses are typically connected by hinge modules to allow the temples to open and fold. However, these smart glasses rely primarily on the deformation of the temples themselves to accommodate users with different head sizes. Since the deformation of the temples is relatively small, their applicability to users with different head sizes is limited. Furthermore, this can easily result in glasses that are too loose or too tight, affecting wearing comfort. Summary of the Invention

[0004] The main objective of this application is to provide a hinge module designed to improve the applicability of smart glasses to users with different head sizes, while also enhancing wearing comfort.

[0005] To achieve the above objectives, the hinge module proposed in this application includes:

[0006] First connector;

[0007] A second connector, rotatably connected to the first connector via a rotating shaft, has an open state, and in the open state, the second connector can rotate and fold towards a first direction and rotate and fold outward towards a second direction opposite to the first direction; and

[0008] A first elastic element is configured to apply a damping elastic force to the second connecting member that is rotated outward, and the direction of the elastic force of the first elastic element intersects the axis of rotation.

[0009] Optionally, the first elastic element is disposed on the first connecting member, and the hinge module further includes a sliding element, which is slidably connected to the first connecting member. The rotating and outwardly turned second connecting member can abut against and drive the sliding element to squeeze the first elastic element.

[0010] Optionally, the slider includes:

[0011] A sliding rod, slidably connected to the first connecting member, wherein the rotating outward-facing second connecting member abuts against and drives the sliding rod; and

[0012] A drive plate is connected to the sliding rod and abuts against the first elastic member.

[0013] Optionally, the first connector is provided with a mounting groove and a connecting hole communicating with the mounting groove, the first elastic element is disposed in the mounting groove, the sliding rod passes through the connecting hole, and the driving plate is disposed in the mounting groove.

[0014] Optionally, the first elastic element and the driving plate are sleeved on the sliding rod located in the mounting groove;

[0015] And / or, the first connector is further provided with a mounting port that connects the connecting hole and the outer surface of the first connector.

[0016] Optionally, the sliding member further includes an abutment plate, which is connected to the sliding rod and located on the side of the driving plate away from the first elastic member. The rotating outward-folding second connecting member can abut against the driving abutment plate.

[0017] Optionally, the second connector has a driving surface, and the abutment plate has an abutment surface on the side opposite to the driving plate; the rotating outward-folding second connector abuts against the abutment surface through the driving surface, and both the driving surface and the abutment surface include an outwardly convex arc surface;

[0018] And / or, the abutment plate extends along the axis of the rotation shaft, and the number of the sliding rod, the driving plate, and the first elastic element are all at least two; at least two of the sliding rods are connected to the abutment plate and are arranged sequentially along the axis of the rotation shaft, each driving plate is connected to one of the sliding rods, and each of the first elastic elements abuts against one of the driving plates.

[0019] Optionally, the first connector is provided with a first connecting ear, and the second connector is provided with a second connecting ear, the second connecting ear and the first connecting ear being disposed opposite to each other;

[0020] The hinge module further includes a rotating shaft and a second elastic element. The rotating shaft passes through the first connecting ear and the second connecting ear, and the second elastic element is sleeved on the rotating shaft and elastically abuts against the first connecting ear and the second connecting ear.

[0021] Optionally, there are two of each of the first connecting ear, the second connecting ear, the rotating shaft, and the second elastic element. The two first connecting ears are spaced apart in the axial direction of the rotating shaft, and a wire passage is formed between the two first connecting ears.

[0022] Each second connecting ear corresponds to one first connecting ear and is located outside the wire passage. Each rotating shaft passes through one second connecting ear and one first connecting ear, and each second elastic element is sleeved on one rotating shaft.

[0023] This application also proposes a smart glasses, including a frame, temples, and a hinge module as described above, wherein a first connector in the hinge module is connected to the frame, and a second connector in the hinge module is connected to the temples.

[0024] Optionally, the smart glasses further include a shaft cover, the shaft cover being projected in a circular shape in the direction of the rotation axis;

[0025] The shaft cover, the frame, and the temples enclose a receiving space, and the hinge module is located within the receiving space.

[0026] Optionally, the shaft cover includes:

[0027] Two end plates, respectively located on opposite sides of the hinge module along the axis of rotation, and coaxially arranged with the axis of rotation; and

[0028] A connecting plate, wherein the opposite ends of the connecting plate are respectively connected to the two end plates;

[0029] At least one of the end plates and / or the connecting plate has two first limiting ribs on its inner side, the two first limiting ribs being spaced apart along the circumference of the end plate, and the second connecting member has a second limiting rib, the second limiting rib being located between the two first limiting ribs.

[0030] The hinge module of this application configures the second connector, which is in the open state, to be able to rotate and fold in a first direction and rotate and fold outward in a second direction opposite to the first direction. This allows the temples connected to the second connector to not only fold but also have an outward folding space in the second direction, making them more suitable for users with larger heads. Furthermore, when the user folds the temples outward, the first elastic element applies a damping force to the moving second connector, causing the temples to clamp to fit the user's head and maintain wearing stability. After the glasses are removed, the first elastic element returns to its original position, causing the temples to automatically return to the open state. Therefore, the hinge module structure in this solution is suitable for users with different head sizes and allows for adjustment of the clamping force to regulate the tightness of the fit based on the user's head size. This improves the applicability of the smart glasses to users with different head sizes and enhances wearing comfort. Moreover, the elastic force direction of the first elastic element in the hinge module of this solution intersects with the axis of rotation. At this point, on the one hand, it facilitates the compression and compact arrangement of the first elastic element when the second connector is folded outward, thereby improving the convenience of manufacturing the hinge module and reducing its overall size, thus enhancing the ease of installation within a limited space. On the other hand, it also increases the utilization efficiency of the elastic force of the first elastic element, thereby increasing its damping effect on the folded second connector. This provides greater adjustment space when adjusting the clamping force according to the user's head size, further improving the applicability and wearing comfort for users with different head sizes.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0047] This application proposes a hinge module that enables a rotatable connection between two components. The following explanation primarily uses the application of this hinge module in smart glasses as an example. It is understood that the hinge module can also be applied to other products requiring folding and outward-folding functions.

[0048] Referring to Figures 1 to 4 and Figures 7 to 9, in one embodiment of this application, the hinge module 10 proposed in this application includes a first connector 11, a second connector 13, and a first elastic member 15. The second connector 13 is rotatably connected to the first connector 11 via a rotating shaft 17. The second connector 13 has an open state, and in the open state, the second connector 13 can rotate and fold towards a first direction and rotate and fold outward towards a second direction opposite to the first direction. The first elastic member 15 is configured to apply a damping elastic force to the rotating and folding second connector 13, and the direction of the elastic force of the first elastic member 15 intersects the axial direction of the rotating shaft 17.

[0049] The first connector 11 can be connected at one end to the frame 30 and at the other end to the second connector 13 for rotatable connection. The first connector 11 and the frame 30 can be connected by threads to improve the convenience and stability of the connection. This threaded connection includes screw connections and combinations of bolts and nuts. Alternatively, the first connector 11 and the frame 30 can be connected by snap-fit ​​or magnetic attraction; this application does not limit the connection method between the first connector 11 and the frame 30. Furthermore, the first connector 11 can be a plate structure (including a single plate and a combination of at least two plates), or it can be a column structure or a base structure; this application does not limit the structural type and shape of the first connector 11.

[0050] The second connector 13 can be connected at one end to the temple 50 and rotatably connected at the other end to the first connector 11. The second connector 13 and the temple 50 can be connected by a thread to improve the convenience and stability of their connection. Alternatively, they can be connected by a snap-fit ​​or magnetic connection; this application does not limit the connection method. Furthermore, the second connector 13 and the first connector 11 can be rotatably connected by a rotating shaft 17, as described below. Alternatively, one of the second connector 13 and the first connector 11 can have a rotating shaft 17, while the other has a insertion hole, allowing the rotating shaft 17 to be inserted into the insertion hole for rotatable connection. Therefore, this application does not limit the rotatable connection structure between the first connector 11 and the second connector 13. Furthermore, the second connector 13 can be a plate structure (including a single plate and a combination of at least two plates), or it can be a column structure or a base structure, etc. This application does not limit the structural type and shape of the second connector 13. Additionally, it should be noted that the second connector 13 is in the open state, as shown in Figure 7, that is, when the temple 50 forms a 90° or approximately 90° angle with the frame 30. At this time, if the second connector 13 rotates in the first direction, or inwards, as shown in Figure 8, the temple 50 can be folded into the frame 30. If the second connector 13 rotates in the second direction, or outwards, as shown in Figure 9, the temple 50 can be further folded outwards to accommodate users with larger heads.

[0051] The first elastic element 15 can be used to apply damping force to the rotating outward-folding second connecting member 13. When the damping force is transmitted to the temple 50 through the second connecting member 13, it can drive the temple 50 to clamp the user's head, thus forming a clamping force between the temple 50 and the user's head. When the axis of rotation 17 is vertical, the direction of the elastic force of the first elastic element 15 can be horizontal. Furthermore, the first elastic element 15 can be disposed on the first connecting member 11 as described below, or it can be disposed on the second connecting member 13, ensuring that the first elastic element 15 can be compressed during the outward-folding process of the second connecting member 13. In addition, the first elastic element 15 can be a spring to provide relatively good elasticity, while also being readily available in the market and easy to install. Of course, the first elastic element 15 can also be a spring sheet, etc. This application does not limit the structural type of the first elastic element 15.

[0052] The hinge module 10 of this application configures the second connector 13, which is in the open state, to be able to rotate and fold in a first direction and rotate and fold outward in a second direction opposite to the first direction. This allows the temple 50, connected to the second connector 13, to not only fold but also have an outward folding space in the second direction, making it more convenient for users with larger heads to wear. Furthermore, when the user folds the temple 50 outward, the first elastic member 15 applies a damping force to the moving second connector 13, causing the temple 50 to fit the user's head and maintain wearing stability. After the glasses are removed, the first elastic member 15 returns to its original position, causing the temple 50 to automatically return to the open state. Therefore, the hinge module 10 in this solution is designed to be suitable for users with different head sizes and allows for adjustment of the clamping force to regulate the tightness of the fit according to the user's head size. This improves the applicability of the smart glasses 100 to users with different head sizes and enhances wearing comfort. Furthermore, in the hinge module 10 of this application, the elastic force direction of the first elastic element 15 is intersecting the axis of rotation 17. This facilitates the compression and compact arrangement of the first elastic element 15 when the second connecting member 13 is folded outwards, improving the manufacturing convenience of the hinge module 10 and reducing its overall volume, thus enhancing the ease of installation within a limited space. On the other hand, it also increases the utilization efficiency of the elastic force of the first elastic element 15, thereby increasing its damping effect on the folded second connecting member 13. This provides greater adjustment space when adjusting the clamping force according to the user's head size, further improving applicability and wearing comfort for users with different head sizes.

[0053] Referring to Figures 4 to 7, in one embodiment of this application, the first elastic member 15 is disposed on the first connector 11, and the hinge module 10 further includes a sliding member 16. The sliding member 16 is slidably connected to the first connector 11, and the rotating outward-folding second connector 13 can abut against and drive the sliding member 16 to squeeze the first elastic member 15.

[0054] The sliding member 16 is an object that is slidably mounted on the first connecting member 11. When the second connecting member 13 rotates outward, the sliding member 16 can be abutted and driven by the second connecting member 13 to compress the first elastic member 15. The sliding member 16 can be, as described below, a sliding rod 161 and a driving plate 163. Of course, the sliding member 16 can also be a plate structure or a column structure, etc. This application does not limit the structural type and shape of the sliding member 16. Furthermore, the first elastic member 15 and the second elastic member 19 can be located on the outside of the first connecting member 11 to facilitate the abutment and driving of the sliding member 16 by the outwardly rotated second connecting member 13.

[0055] In this embodiment, the first elastic element 15 is disposed on the first connecting member 11, which allows the first elastic element 15 to be fixedly disposed, thereby improving the stability of the installation of the first elastic element 15 and the stability of its subsequent operation. Furthermore, the addition of a sliding member 16 facilitates the sequential contact and engagement of the first elastic element 15, the sliding member 16, and the second connecting member 13, improving the stability of the transmission of the elastic force of the first elastic element 15.

[0056] Referring to Figures 4 to 7, in one embodiment of this application, the sliding member 16 includes a sliding rod 161 and a driving plate 163. The sliding rod 161 is slidably connected to the first connecting member 11, and the rotating outward-folding second connecting member 13 can abut against the sliding rod 161. The driving plate 163 is connected to the sliding rod 161 and abuts against the first elastic member 15.

[0057] The sliding rod 161 can be slidably mounted on the first connecting member 11, and can also be abutted and driven by the outwardly turned second connecting member 13. The sliding rod 161 can extend along the elastic direction of the first elastic member 15. The cross-section of the sliding rod 161 can be any shape, such as circular, square, or rectangular. The driving plate 163 can abut against the first elastic member 15, thereby compressing the first elastic member 15 when the sliding rod 161 is abutted and driven by the outwardly turned second connecting member 13. The driving plate 163 can be any shape, such as square, rectangular, or circular.

[0058] In this embodiment, the sliding member 16 is configured to include a sliding rod 161 and a driving plate 163, so that the sliding member 16 can be slidably connected to and press against the first elastic member 15 through different components, thereby improving the convenience of installing and arranging the first connecting member 11, the first elastic member 15, and the sliding member 16. Moreover, by using the driving plate 163 to abut and press against the first elastic member 15, the abutment and cooperation between the two is also convenient, which helps to improve the stability of pressing against the first elastic member 15.

[0059] Referring to Figures 4 to 7, in one embodiment of this application, the first connector 11 is provided with a mounting groove 111 and a connecting hole 112 that connects to the mounting groove 111, the first elastic member 15 is provided in the mounting groove 111, the sliding rod 161 passes through the connecting hole 112, and the driving plate 163 is provided in the mounting groove 111.

[0060] In this embodiment, by providing the mounting groove 111 and the connecting hole 112, the first elastic member 15 and the sliding member 16 can be conveniently installed and limited. Furthermore, the structure of the mounting groove 111 and the connecting hole 112 is relatively simple, which improves the convenience and stability of installing the first elastic member 15 and the sliding member 16. In addition, it can improve the compactness of the distribution of the first elastic member 15 and the sliding member 16 on the first connecting member 11, thereby further reducing the overall volume of the hinge module 10.

[0061] Referring to Figures 4 to 7, in one embodiment of this application, the first elastic member 15 and the driving plate 163 are sleeved on the sliding rod 161 located in the mounting groove 111.

[0062] In this embodiment, the driving plate 163 is sleeved on the sliding rod 161 located in the mounting groove 111, so that the end of the sliding rod 161 located in the mounting groove 111 can be further inserted into the first elastic member 15. The sliding rod 161 can further guide the direction of the elastic force of the first elastic member 15, so that the first elastic member 15 can accurately and stably apply damping elastic force to the outwardly folded second connecting member 13. Of course, in other embodiments, the driving plate 163 can also be directly connected to the end face of the sliding rod 161 located in the mounting groove 111.

[0063] Referring to Figures 5 and 6, in one embodiment of this application, the first connector 11 is further provided with a connecting hole 112 and a mounting port 113 on the outer surface of the first connector 11.

[0064] In this embodiment, the mounting port 113 can penetrate the outer surface of the first connector 11, so that when the first elastic member 15 is installed from the opening of the mounting groove 111 into the mounting groove 111, the sliding member 16 can be installed from the mounting port 113 into the communicating hole 112, thereby improving the convenience of installing the sliding member 16.

[0065] Referring to Figures 4 to 7, in one embodiment of this application, the sliding member 16 further includes an abutment plate 165. The abutment plate 165 is connected to the sliding rod 161 and is located on the side of the driving plate 163 away from the first elastic member 15. The rotating outward-folding second connecting member 13 can abut against the driving abutment plate 165.

[0066] In this embodiment, the abutment plate 165 is connected to one end of the sliding rod 161 located outside the mounting groove 111, so that when the second connecting member 13 is folded outward, the second connecting member 13 can abut and drive the abutment plate 165. At this time, the abutment plate 165 facilitates the abutment engagement with the second connecting member 13, thereby improving the stability of the abutment and drive of the sliding member 16 by the folded-out second connecting member 13.

[0067] Referring to Figures 7 to 9, in one embodiment of this application, the second connector 13 is provided with a driving surface 131, and the abutment plate 165 is provided with an abutment surface 167 on the side opposite to the driving plate 163; the rotating outward-folding second connector 13 abuts against the abutment surface 167 through the driving surface 131, and both the driving surface 131 and the abutment surface 167 include an outwardly convex arc surface.

[0068] In this embodiment, both the driving surface 131 and the abutting surface 167 are configured to include convex arc surfaces, so that when the second connector 13 is in the open position and the maximum outward tilt position, the abutting positions of the driving surface 131 and the abutting surface 167 are near the center of the sliding rod 161. This improves the stability of the sliding rod 161, thereby ensuring that the torque exerted by the elastic force of the first elastic member 15 on the second connector 13 remains within a relatively stable range. In other words, it improves the stability of the clamping force of the temple 50 on the user's head, further enhancing wearing comfort.

[0069] Referring to Figures 5 and 6, in one embodiment of this application, the abutment plate 165 extends along the axis of the rotation shaft 17, and the number of sliding rods 161, driving plates 163, and first elastic elements 15 are all at least two; at least two sliding rods 161 are connected to the abutment plate 165 and are arranged sequentially along the axis of the rotation shaft 17, each driving plate 163 is connected to one sliding rod 161, and each first elastic element 15 abuts against one driving plate 163.

[0070] In this embodiment, the number of sliding rods 161, driving plates 163, and first elastic members 15 are all set to at least two. This allows at least two driving plates 163 to press at least two first elastic members 15 when the outwardly folded second connecting member 13 abuts against one abutment plate 165, thereby increasing the damping force applied to the outwardly folded second connecting member 13. Furthermore, at least two first elastic members 15 can be pressed simultaneously, improving the uniformity and stability of the elastic force. Additionally, at least two mounting slots 111 and connecting holes 112 described above can be correspondingly provided for the installation of the corresponding first elastic members 15 and sliding rods 161.

[0071] In one embodiment of this application, the sliding rod 161, the driving plate 163, and the abutment plate 165 are an integral structure.

[0072] A one-piece structure means that it can be formed into a single unit after manufacturing. This can be achieved through injection molding, stamping, or casting.

[0073] In this embodiment, the sliding rod 161, the driving plate 163, and the abutment plate 165 are set as an integral structure, which can improve the production efficiency of the sliding member 16 and enhance the connection strength between the various components, thereby improving the overall strength of the sliding member 16.

[0074] Referring to Figures 4 to 6, in one embodiment of this application, the first connector 11 is provided with a first connecting ear 114, and the second connector 13 is provided with a second connecting ear 132. The second connecting ear 132 and the first connecting ear 114 are arranged opposite to each other. The hinge module 10 also includes a rotating shaft 17 and a second elastic member 19. The rotating shaft 17 passes through the first connecting ear 114 and the second connecting ear 132, and the second elastic member 19 is sleeved on the rotating shaft 17 and elastically abuts against the first connecting ear 114 and the second connecting ear 132 (that is, the second elastic member 19 has a pre-compression state, and the second elastic member 19 can be a spring or a sheet, etc.).

[0075] In this embodiment, the rotational connection between the first connector 11 and the second connector 13 is achieved by passing the rotating shaft 17 through the first connecting ear 114 and the second connecting ear 132. This simplifies the connection structure of the first connector 11 and the second connector 13, thereby improving the convenience of connecting the first connector 11 and the second connector 13. Simultaneously, the rotating shaft 17 also provides a mounting position for the second elastic member 19, allowing for a damping feel when the second connector 13 is folded or rotated from a folded position to an open position, further enhancing the user experience. The rotating shaft 17 can be in the form of a pin or a screw.

[0076] Referring to Figures 4 to 6, in one embodiment of this application, there are two first connecting ears 114, two second connecting ears 132, two rotating shafts 17, and two second elastic members 19. The two first connecting ears 114 are spaced apart in the axial direction of the rotating shaft 17, and a wire passage 115 is formed between the two first connecting ears 114. Each second connecting ear 132 corresponds to one first connecting ear 114 and is located outside the wire passage 115. Each rotating shaft 17 passes through one second connecting ear 132 and one first connecting ear 114, and each second elastic member 19 is sleeved on one rotating shaft 17.

[0077] In this embodiment, the number of the first connecting ear 114, the second connecting ear 132, the rotating shaft 17, and the second elastic member 19 are all set to two. This improves the stability of the connection between the first connecting member 11 and the second connecting member 13, and enhances the damping effect on the second connecting member 13 when folding or rotating from the folded position to the open position. Furthermore, a wire passage 115 is formed between the two first connecting ears 114. This allows the signal wire to pass through easily, facilitating signal transmission between the temple 50 and the front frame. Simultaneously, passing the signal wire through the middle of the hinge module 10 reduces the length variation of the signal wire during the rotation of the hinge module 10, thus reducing the risk of signal wire bending. In addition, this arrangement saves space in the thickness direction of the hinge module 10, which is more advantageous for the overall thickness dimension design of the temple 50, while also reducing the weight of the hinge module 10.

[0078] Referring to Figures 1 and 2, this application also proposes a smart glasses 100, which includes a frame 30, temples 50, and a hinge module 10. The specific structure of the hinge module 10 is as described in the above embodiments. Since this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Specifically, the first connector 11 in the hinge module 10 is connected to the frame 30, and the second connector 13 in the hinge module 10 is connected to the temples 50.

[0079] Referring to Figures 1 and 2, in one embodiment of this application, the smart glasses 100 further includes a shaft cover 70, which is projected as a circle in the direction of the axis of rotation 17; the shaft cover 70, the frame 30, and the temples 50 enclose a receiving space 100a, and the hinge module 10 is located within the receiving space 100a.

[0080] In this embodiment, the hinge module 10 is arranged in a concealed space 100a formed by the shaft cover 70, the frame 30, and the temple 50. This allows the hinge module 10 to be hidden, thereby improving its protection and enhancing the aesthetics of the smart glasses 100, thus increasing its market competitiveness. To simplify the structure of the concealed space 100a, a first groove 31 can be provided on the frame 30, a second groove 51 can be provided on the second connector 13, and a third groove 71 can be provided on the shaft cover 70. The first groove 31, the second groove 51, and the third groove 71 together form the concealed space 100a. Part of the first connector 11 can be installed in the first groove 31, and part of the second connector 13 can be installed in the second groove 51. The surfaces of the first and second connectors 11 and the shaft cover 70 that abut against each other can be rounded to allow the temple 50 to rotate about the axis of the shaft cover 70.

[0081] Referring to Figures 1 and 2, in one embodiment of this application, the shaft cover 70 includes two end plates 72 and a connecting plate 73. The two end plates 72 are located on opposite sides of the hinge module 10 along the axis of the rotation shaft 17, and are coaxially arranged with the rotation axes of the first connecting member 11 and the second connecting member 13. The opposite ends of the connecting plate 73 are respectively connected to the two end plates 72. At least one end plate 72 and / or the connecting plate 73 is provided with two first limiting ribs 74 on its inner side. The two first limiting ribs 74 are spaced apart along the circumference of the end plate 72. The second connecting member 13 is provided with a second limiting rib 133, which is located between the two first limiting ribs 74.

[0082] In this embodiment, the shaft cover 70 includes two end plates 72 and a connecting plate 73, so that the side circumferential surface of the shaft cover 70 is not closed, thereby facilitating the avoidance of the portion of the first connecting member 11, the portion of the second connecting member 13, and the signal line passing through the wire passage 115 as described above. The two end plates 72 and the connecting plate 73 together form the third groove 71 described above. Furthermore, in the open state, the connecting plate 73 can be located inside the shaft cover 70. Further, the two first limiting ribs 74 and the second limiting rib 133 allow the second connecting member 13 to rotate, thereby driving the shaft cover 70 to rotate. Thus, in the folded, open, and outward-folding states, the shaft cover 70 effectively shields the internal structure, further improving the aesthetics of the smart glasses 100 and enhancing the user experience. The first limiting rib 74 can be connected to only one end plate 72 or both end plates 72, or it can be connected to only the connecting plate 73, or it can be connected to both end plate 72 and connecting plate 73 at the same time; the second limiting rib 133 can be set on the second connecting ear 132 of the second connector 13.

[0083] Referring to Figures 1 and 2, in one embodiment of this application, the second connecting ear 132 of the second connector 13 may be provided with a circular boss 134. The boss 134 and the rotating shaft 17 are coaxially arranged. The end plate 72 may be provided with a socket 721. The boss 134 is inserted into the socket 721 to realize the rotational engagement between the shaft cover 70 and the second connector 13, thereby improving the stability of the installation between them.

[0084] Referring to Figures 1 and 2, in one embodiment of this application, a flange 722 may be protruding from the outer side of the end plate 72. The flange 722 extends circumferentially along the end plate 72. A groove 100b may be provided on the inner side of the frame 30 and the temple 50. The flange 722 is accommodated in the groove 100b to ensure the circumferential end difference between the end plate 72 and the frame 30 and the temple 50, and to further improve the stability of the connection between the shaft cover 70, the frame 30, and the temple 50. The groove 100b on the frame 30 may be located on the groove wall of the first groove 31 described above, and the groove 100b on the temple 50 may be located on the groove wall of the second groove 51 described above.
