[0041] The specific embodiments of the AR glasses of the present application are described in detail below with reference to the accompanying drawings.

[0042] Figure 1 Schematic diagram of the structure of the AR glasses in this embodiment.

[0043] refer to Figure 1In this embodiment, the AR glasses include a glasses body 1, a night vision device 2 and an electrical terminal. The glasses body 1 is used to present a virtual and real picture. A card slot 13 opening outward is provided on the glasses body 1. The night vision device 2 is provided with a snap-in 21, which can be clamped in the card slot 13 or detached from the card slot 13 to achieve a detachable connection between the night vision device 2 and the glasses body 1. The electrical terminal includes a first terminal 31 provided on the snap-in 21 and a second terminal 32 provided on the glasses body 1 and arranged corresponding to the card slot 13. The first terminal 31 is electrically connected to the night vision device 2, and the second terminal 32 is electrically connected to the glasses body 1. When the snap-in 21 is clamped in the card slot 13, the first terminal 31 contacts the second terminal 32 to achieve an electrical connection between the night vision device 2 and the glasses body 1.

[0044] In the above-mentioned AR glasses, the glasses body 1 can be used independently to present a picture combining virtual and reality to the user.

[0045] Alternatively, the user can use the night vision goggles 2 in combination with the glasses body 1, and use the night vision goggles 2 to enable the AR glasses to adapt to low-light environments to meet the user's needs for using the AR glasses in low-light environments.

[0046] Among them, when the night vision goggles 2 are connected to the glasses body 1, the first terminal 31 and the second terminal 32 can be brought into contact to realize the electrical connection between the night vision goggles 2 and the glasses body 1, and the glasses body 1 can immediately power the night vision goggles 2, and the night vision goggles 2 can transmit electrical signals to the glasses body 1. The operation is simple and convenient, which can meet the user's demand for the night vision goggles 2 to be connected and used immediately.

[0047] In addition, in a scenario where the night vision goggles 2 are not needed, the night vision goggles 2 can be removed from the glasses body 1, which can reduce the weight of the AR glasses and reduce the user's weight when the user uses the glasses body 1 alone.

[0048] Alternatively, when the AR glasses are not in use, the night vision goggles 2 can be removed from the glasses body 1, so that the glasses body 1 and the night vision goggles 2 can be stored separately.

[0049] Figure 2 Schematic diagram of the structure of the eyeglass body 1 in this embodiment.

[0050] refer to Figure 2 The eyeglass body 1 includes a main body portion 11 and an eyeglass module 14 .

[0051] In this embodiment, the main body 11 may be a headband. The headband is annular and can be worn directly on the head by the user; moreover, the headband is small in size and light in weight, so as to meet the user's need to wear it for a long time.

[0052] The headband includes a band body and an adjustment belt, and the band body and the adjustment belt are detachably connected to enclose a ring structure. A plurality of adjustment holes are arranged at intervals on the adjustment belt, and the plurality of adjustment holes are distributed at intervals along the length direction of the adjustment belt. Adjustment pieces are connected to both ends of the band body in the length direction. In practical applications, the user can insert the adjustment piece into any adjustment hole according to actual use needs, so as to adjust the caliber size of the ring structure formed after the band body and the adjustment belt are connected, so as to meet the use needs of users with different head circumferences and enhance the user experience.

[0053] In other embodiments, the headband with a closed loop structure can be directly disconnected to have two states: closed and unfolded. The two ends of the disconnected part of the headband are detachably connected by an adjusting member. A plurality of adjustment holes are arranged at intervals on the headband. When the headband is in the unfolded state, the plurality of adjustment holes are distributed at intervals along the length direction of the headband at one end of the headband. When in use, the adjusting member passes through the other end of the headband and one of the adjustment holes at the same time to close the headband.

[0054] In this embodiment, the headband may further include a protective pad, which is inserted into the adjustment strap. The inner wall of the protective pad is arc-shaped, and is used to fit the back of the user's head to relieve the pressure of the headband on the user's head, so as to meet the user's long-term use needs and improve the user's comfort and experience.

[0055] In some examples, the main body can also be a helmet, such as an industrial helmet, a fire helmet, etc., which can be worn by users in places where safety protection measures are required (such as construction sites, fire scenes, etc.) to protect the user's head.

[0056] The glasses module 14 is disposed on the main body 11 and is electrically connected to the main body 11. When the glasses body 1 is used, the main body 11 can be worn on the head so that the glasses module 14 is located in front of the user's eyes. The user can see the real scene through the glasses module 14, and the real scene that can be seen can be transmitted to the main body 11 through the glasses module 14, and the virtual information related to the scene can be transmitted and projected to the glasses module 14 after matching processing by the main body 11, so that the user can see the virtual and real pictures at the same time. In addition, the glasses body 1 can be worn on the head through the main body 11, so as to meet the user's long-term use needs and improve the user's use experience.

[0057] In this embodiment, a card slot 13 is provided on the outer wall of the glasses body 1 for realizing the connection between other functional accessories and the glasses body 1 so as to cooperate with the glasses body 1 for use, thereby adapting to the use of AR glasses in different scenarios.

[0058] Figure 3 for Figure 2 Enlarged structural diagram at A in the middle.

[0059] refer to Figure 2and Figure 3 The eyeglass body 1 further includes two stopper parts 14 arranged on the outside of the main body part 11, with a gap between the two stopper parts 14, and the two stopper parts 14 enclose a slot 13. The outside here refers to the side of the eyeglass body 1 that is away from the user's head when the eyeglass body 1 is worn and used, and the inside is the opposite.

[0060] The limiting portion 14 is provided with a limiting groove 141 opening toward the card slot 13, and the limiting groove 141 communicates with the card slot 13. When other functional accessories are connected to the eyeglass body 1, the limiting groove 141 cooperates with the card slot 13 to strengthen the connection strength between the other functional accessories and the eyeglass body 1 and improve the connection stability.

[0061] In other embodiments, the slot 13 may also be formed by directly recessing the outer wall of the main body 11 inward.

[0062] In this embodiment, the functional accessory described above may be a night vision device 2, which is used to improve the user's visual ability in a low-light environment.

[0063] In other embodiments, the functional accessory described above may be a telescope or the like.

[0064] Figure 4 Schematic diagram of the structure of the night vision device 2 in this embodiment.

[0065] refer to Figure 4 The night vision device 2 includes a shell, an objective lens and a processor arranged inside the shell.

[0066] One axial end of the housing is open for allowing external light to enter the housing.

[0067] The objective lens is arranged opposite to the opening end of the housing, and is used to collect external light, that is, the external light enters the interior of the housing through the objective lens from the opening end of the housing, and forms an optical signal.

[0068] The processor is located on the side of the objective lens away from the open end of the housing, and the processor is in communication with the eyeglass body 1. The processor can receive optical signals and convert the optical signals into electrical signals, and then transmit the electrical signals to the eyeglass body 1, so that the real scene can be presented to the user through the eyeglass body 1.

[0069] refer to Figure 1 to Figure 4 The night vision goggles 2 are detachably connected to the glasses body 1, so that quick connection or quick disassembly between the night vision goggles 2 and the glasses body 1 can be achieved, so that users can choose the usage form of the AR glasses according to actual conditions.

[0070] In this embodiment, the night vision device 2 is connected to the eyeglass body 1. The night vision device 2 is provided with a clamping member 21, which can be clamped in the clamping slot 13 or detached from the clamping slot 13 to achieve a detachable connection between the night vision device 2 and the eyeglass body 1.

[0071] In addition, the opposite ends of the snap-fitting member 21 can be correspondingly built into the limiting grooves 141 of the two limiting parts 14, so that the limiting grooves 141 cooperate with the snap-fitting slots 13 to enhance the snap-fitting strength of the snap-fitting member 21, thereby enhancing the stability of the connection between the night vision device 2 and the eyeglass body 1.

[0072] In other embodiments, the snap-in component 21 may also be located on the eyeglass body 1 , and the snap-in slot 13 may be located on the night vision device 2 .

[0073] Figure 5 Schematic diagram of the structure of the clamping member 21 in this embodiment.

[0074] refer to Figure 5 In this embodiment, the clamping member 21 includes two legs 211 and a connecting portion 212 connected between the two legs 211. The connecting portion 212 is respectively connected to the two legs 211 to form an integral structure.

[0075] Both legs 211 have free arms 2111, and the free arms 2111 of the two legs 211 are located on the same side of the connecting portion 212. The two free arms 2111 can be close to each other, so that the dimension between the outer sides of the two legs 211 becomes smaller, and it is easy to enter the slot 13 and the limiting slot 141. Alternatively, the two free arms 2111 can be away from each other, so that the free arms 2111 of the two legs 211 can be reset, so that the dimension between the two opposite sides of the two legs 211 returns to the initial state, so that they can abut against the inner peripheral walls of the slot 13 and the limiting slot 141, and be stuck in the slot 13.

[0076] The clamping member 21 also includes an elastic member, which is arranged in the connecting portion 212 and abuts between the two legs 211. The elastic member can accumulate elastic potential energy when the two free arms 2111 are brought closer to each other due to the application of external force, and when the external force is removed, the elastic member will release the elastic potential energy in the process of restoring the natural state, so that the two free arms 2111 rebound and return to their original position.

[0077] In this embodiment, the elastic member may be a torsion spring. In this case, the elastic member includes a spiral body and two elastic arms arranged at opposite ends of the spiral body. The spiral body is cylindrical, and the two elastic arms are arranged at the axial ends of the spiral body, and the two elastic arms are located at the radial ends of the spiral body, and the elastic arms are located on the tangent of the spiral body. The spiral body is located between the two legs 211, and the axial direction of the spiral body is perpendicular to the line between the two legs 211. The two elastic arms are in one-to-one correspondence with the two legs 211 and are in contact with each other.

[0078] When an external force is applied to the two free arms 2111, the two elastic arms approach each other as the two legs 211 approach each other and drive the spiral body to rotate. During this process, the elastic member can accumulate elastic potential energy. When the external force is removed, the elastic arms and the spiral body release the elastic potential energy in the process of restoring their natural state, causing the two free arms 2111 to rebound and return to their original position.

[0079] In other embodiments, the elastic member may also be a spring. In this case, the two axial ends of the elastic member abut between the two legs 211, and when an external force is applied to the two free arms 2111, the elastic member is compressed as the two legs 211 approach each other to accumulate elastic potential energy, and when the external force is removed, the elastic member releases the elastic potential energy in the process of restoring the natural telescopic state, so that the two free arms 2111 rebound and return to their original positions.

[0080] In this embodiment, the outer ends of the two legs 211 are recessed toward each other to form a clamping portion 2112 with an opening facing away from each other. The clamping portion 2112 is used to clamp with the clamping slot 13, and can play a role of strengthening the limit, thereby improving the stability of the clamping of the clamping member 21 with the clamping slot 13. Specifically, the clamping portion 2112 is used to accommodate the clamping limit portion 14.

[0081] In actual application, by applying pressure to the two free arms 2111 of the clamping member 21, the two free arms 2111 are brought closer to each other, so that the distance between the two free arms 2111 on the opposite sides can be reduced, so that the two legs 211 can enter the clamping slot 13 and the limiting slot 141 at the same time, and the pressing force applied to the two legs 211 is removed. Then, by pushing the clamping member 21, the two legs 211 of the clamping member 21 slide in the limiting slot 141 of the limiting portion 14 respectively, until the limiting portion 14 is accommodated in the clamping portion 2112, the clamping member 21 is clamped with the clamping slot 13, and the night vision device 2 is connected to the eyeglass body 1.

[0082] In other embodiments, pressure can also be applied to the two free arms 2111 of the clamping member 21 to bring the two free arms 2111 closer to each other, thereby reducing the distance between the two free arms 2111 on the opposite sides. Then, the clamping portion 2112 of one of the legs 211 is aligned with a limiting portion 14, and the limiting portion 14 is directly accommodated in the clamping portion 2112 by applying external force. The above operation is then repeated to allow the other limiting portion 14 to be directly accommodated in the other clamping portion 2112.

[0083] refer to Figure 2, a positioning member 15 is also provided on the eyeglass body 1. When the clamping member 21 is clamped in the clamping slot 13, the positioning member 15 is located between the two legs 211, and the positioning member 15 is used to abut against the legs 211 and / or to abut against the connecting portion 212. When the night vision device 2 is removed from the eyeglass body 1, the user can judge the size of the pressing force required to be applied to the two legs 211 according to the distance between the two legs 211 and the positioning member 15, so that the pressing force when both legs 211 abut against the positioning member 15 is the upper limit, so as to prevent the legs 211 from being damaged by excessive pressing force applied to the two legs 211. In addition, when the night vision goggles 2 are connected to the eyeglass body 1, the positioning member 15 can also be used as a condition for judging whether the snap-in member 21 and the card slot 13 are completely snap-fitted, that is, the limiting portion 14 is completely accommodated in the snap-in portion 2112, and at the same time the connecting portion 212 is in contact with the positioning member 15, which indicates that the snap-in member 21 and the card slot 13 are completely snap-fitted, and the night vision goggles 2 are successfully connected to the eyeglass body 1, which is convenient for users to refer to for operation.

[0084] In other embodiments, the night vision device 2 can also be threadedly connected to the eyeglass body 1. The clamping member 21 is provided with an external thread, and the clamping slot 13 is provided with an internal thread matching the external thread, and the external thread and the internal thread are threadedly connected to achieve the connection and fixation of the night vision device 2 and the eyeglass body 1.

[0085] refer to Figure 3 and Figure 4 The electrical terminals include a first terminal 31 provided on the clamping member 21 and a second terminal 32 provided on the eyeglass body 1 and arranged corresponding to the card slot 13. The first terminal 31 is electrically connected to the night vision device 2, and the second terminal 32 is electrically connected to the eyeglass body 1. When the clamping member 21 is clamped in the card slot 13, the first terminal 31 and the second terminal 32 can be brought into contact to realize the electrical connection between the night vision device 2 and the eyeglass body 1, and the eyeglass body 1 can immediately realize the power supply of the night vision device 2 to the eyeglass body 1, and the night vision device 2 can transmit electrical signals to the eyeglass body 1. The operation is simple and convenient, and can meet the user's demand for the night vision device 2 to be connected and used immediately.

[0086] Figure 6 for Figure 1 AA direction cross-sectional view of the AR glasses.

[0087] refer to Figure 6In this embodiment, the first terminal 31 includes a main body 311 and a terminal 312. The main body 311 is fixed in the connecting portion 212, and the terminal 312 extends into the end of the main body 311 away from the night vision device 2, and is movably connected to the main body 311, and can move toward the direction close to the night vision device 2 to be accommodated in the connecting portion 212, or protrude from the connecting portion 212 in the direction away from the night vision device 2. When the night vision device 2 is connected to the eyeglass body 1, in the process of pushing the clamping member 21 to slide relative to the limiting portion 14, the terminal 312 is blocked by the eyeglass body 1 and moves toward the direction close to the night vision device 2 to be accommodated in the connecting portion 212, so as to ensure the smoothness of the sliding of the clamping member 21. When the clamping member 21 is clamped with the card slot 13, the terminal 312 protrudes from the connecting portion 212 in the direction away from the night vision device 2 and contacts with the second terminal 32, so as to realize the electrical connection between the first terminal 31 and the second terminal 32.

[0088] refer to Figure 1 and Figure 6 In this embodiment, the AR glasses also include a rotating component, which is connected between the snap-in component 21 and the night vision goggles 2, and is used to realize a rotatable connection between the night vision goggles 2 and the snap-in component 21. The user can adjust the angle of the night vision goggles 2 relative to the glasses body 1 by rotating the night vision goggles 2 relative to the snap-in component 21. In this way, the exit end of the night vision goggles 2 can be rotated toward the viewing angle desired by the user to meet the user's usage needs and improve the user's usage experience.

[0089] Exemplarily, the rotating assembly includes two connecting seats 41 and a rotating shaft 42, wherein one connecting seat 41 is connected to the clamping member 21, and the other connecting seat 41 is connected to the night vision device 2. The rotating shaft 42 is passed through the two connecting seats 41, the rotating shaft 42 is fixedly connected to one of the connecting seats 41, and the rotating shaft 42 is rotatably connected to the other connecting seat 41.

The operation is simple and convenient, and can meet the user's needs for the night vision goggles to be connected and used immediately.

[0092] In addition, in scenarios where night vision goggles are not needed, the night vision goggles can be removed from the glasses body, which can reduce the weight of the AR glasses and reduce the user's burden when the user uses the glasses body alone.
