DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides an intelligent AR head-mounted device, such as Figures 1 to 6As shown, it includes a body 1, which is internally provided with two frames 2, each of which has lenses built into it. The frames 2 are mounted inside the body 1 using movable parts. Pin plates 3 are provided on both sides of the body 1. The front ends of the pin plates 3 are inserted into the side grooves 101 of the body 1. The rear ends of the pin plates 3 are hingedly connected to a rotating frame 4, and a strap 5 is connected between the two rotating frames 4. Two frames 2 with lenses built into them are placed inside the rear side of the body 1. When the rear side of the body 1 is aligned with the user's face, the frames 2 are moved inside the body 1 through the movable parts, so that the user's eyes correspond one-to-one with the two frames 2. At this time, the strap 5 is at the back of the user's head, and the user has completed wearing the body 1.

[0028] The pin plate 3 is inserted into the body 1 by means of movable parts, and the movable parts include: two movable plates 6, an insertion rod 7, an inner rod 8, a first elastic member 9, a side tube 10 and a rotating sleeve 11, and the first elastic member 9 is set as a spring sheet; a side tube 10 is fixed to the outer side of the pin plate 3, the insertion rod 7 spirally passes through the side tube 10, and the inner end of the insertion rod 7 is inserted into the pin plate 3 through the side tube 10, an inner groove is provided inside the pin plate 3, and two opposite movable plates 6 are provided inside the inner groove, the inner end of the insertion rod 7 squeezes the first inclined surface 601 of the inner end of the movable plate 6, the movable plate 6 is sleeved on the surface of the inner rod 8 by means of the movable groove, and the outer side of the movable groove is connected to the inner rod 8 by means of the first elastic member 9, and the elastic force of the first elastic member 9 makes the two movable plates 6 approach each other. Both end surfaces of the body 1 are provided with a slide groove 102, and the side tubes 10 on the outer side of the pin plate 3 extend through the slide groove 102. When the pin plate 3 moves inside the side groove 101, the moving pin plate 3 causes the side tubes 10 to move inside the slide groove 102. Before the user puts on the body 1, the pin plate 3 moves backward. The pin plate 3 moving backward inside the side groove 101 pulls the two movable plates 6 to move backward synchronously, and the moving pin plate 3 causes the side tubes 10 to move backward inside the slide groove 102 until the side tubes 10 are at the rear side of the slide groove 102. At this point, the pin plate 3 has been pulled out of the side groove 101 the longest distance, and the strap 5 is farthest from the body 1.

[0029] The first inclined surface 601 is tilted, and the first inclined surface 601 corresponds to the inner end of the insertion rod 7. The inward-moving insertion rod 7 squeezes the first inclined surface 601, and the two opposite movable plates 6 are separated from each other by squeezing. The rear side of the body 1 is aligned with the user's eyes, and the pin plate 3 is pushed forward. The forward-moving pin plate 3 moves forward inside the side groove 101, and the forward-moving pin plate 3 drives the side tube 10 to move forward inside the slide groove 102 until the strap 5 fits in place with the back of the user's head. At this time, the rotating sleeve 11 is rotated. Since the insertion rod 7 is screwed into the side tube 10, the rotating sleeve 11 causes the insertion rod 7 to rotate inside the side tube 10. The rotating insertion rod 7 gradually enters the inner groove of the pin plate 3, and the inner end of the rotating insertion rod 7 gradually squeezes the first inclined surface of the movable plate 6. Surface 601, the pressure of the insertion rod 7 on the first inclined surface 601 causes the movable plate 6 to move inside the inner groove. At this time, the two movable plates 6 are separated from each other, and the movable plate 6 moves on the surface of the inner rod 8 using the movable groove. At this time, the two relative movable plates 6 are separated from each other, and the moving movable plate 6 cooperates to pull the first elastic member 9, and the outer end of the movable plate 6 moves out of the inner groove until the outer end of the top movable plate 6 squeezes the top of the side groove 101, and the outer end of the bottom movable plate 6 squeezes the bottom of the side groove 101. At this time, the inner surface of the rotating sleeve 11 is in contact with the end face of the body 1.

[0030] By squeezing and fitting the outer end of the movable plate 6 with the side groove 101, the movable plate 6 is prevented from moving freely inside the side groove 101, and the rotating sleeve 11 is tightly fitted with the end face of the body 1, so as to prevent the pin plate 3 from moving freely inside the side groove 101, thereby facilitating the fit of the strap 5 with the back of the user's head, ensuring that the body 1 is sleeved on the user's brain, and the restriction of the pin plate 3 by the movable parts facilitates the entire body 1 to adapt to the brains of different users.

[0031] exist Figures 2 to 4 In the embodiment, the movable parts include a skateboard 12, a bottom rod 13 and a circular plate 14; the skateboard 12 is inside the body 1, and an inner cavity corresponding to the skateboard 12 is provided inside the body 1, a cross bar 15 is fixed inside the inner cavity, the skateboard 12 is slidably sleeved on the surface of the cross bar 15, the bottom surface of the skateboard 12 is fixed with the round plate 14 by the bottom rod 13, and a charging interface is provided on the bottom surface of the round plate 14, and the skateboards 12 are connected to adjacent skateboards 12 by wires, the rear side of the skateboard 12 is connected to the frame 2 by a support rod, and a transverse groove 103 corresponding to the support rod is provided inside the body 1, and a bottom groove 104 corresponding to the bottom rod 13 is provided on the bottom surface of the body 1, and a corresponding groove 105 is provided on the bottom of the rear side of the body 1. When the rear side of the body 1 is aligned with the user's eyes, the circular plate 14 is pushed to move at the bottom of the body 1. The moving circular plate 14 drives the bottom rod 13 to move inside the bottom groove 104. At this time, the bottom rod 13 makes the slide plate 12 slide on the surface of the cross bar 15. The moving slide plate 12 uses the support rod to drive the frame 2 to move. At this time, the support rod moves inside the cross groove 103, making it convenient for the frame 2 to correspond with the user's eyes, and the position of the frame 2 is adjusted according to the distance between the two eyes.

[0032] exist Figure 1 、 Figure 5 、 Figure 7 and Figure 8 In the embodiment, the rotating frame 4 is rotatably engaged with the pin plate 3 using a limiting component. The limiting component includes: a slide frame 16, an inner block 17, a vertical rod 18, and a plug-in portion. The inner block 17 is fixed to the outer side of the pin plate 3, and the slide frame 16 is vertically sleeved on the outer side of the inner block 17. The vertical rod 18 is fixed to the bottom surface of the inner block 17 and extends through the bottom surface of the slide frame 16. The plug-in portion is installed at the bottom of the front side of the slide frame 16. The surface of the vertical rod 18 is provided with multiple notches 19. The plug-in portion cooperates with the notches 19 to lock the slide frame 16. The rotating frame 4 is provided with multiple teeth 401 on the surface, and multiple tooth grooves 161 are provided on the rear side of the slide frame 16. The teeth 401 cooperate with the tooth grooves 161. The rotating rotating frame 4 utilizes the teeth 401 to move the slide frame 16 up and down on the surface of the inner block 17. When the strap 5 rotates upward, the strap 5 drives the rotating frame 4 to rotate at the rear end of the pin plate 3. The clockwise rotating rotating frame 4 drives the multiple teeth 401 to rotate. Since the teeth 401 correspond to the tooth grooves 161, the rotating rotating frame 4 uses the multiple teeth 401 to make the sliding frame 16 move downward on the inner block 17. The downward sliding frame 16 moves downward on the surface of the vertical rod 18 until the strap 5 rotates to the appropriate position, and the rotating frame 4 stops rotating. At this time, the plug-in part cooperates with the notch 19 to complete the limitation of the rotating frame 4, preventing the rotating frame 4 from rotating arbitrarily at the rear end of the pin plate 3, and facilitating the user to automatically adjust the position of the strap 5.

[0033] When the inclined strap 5 cannot ensure the stability of the body 1, the strap 5 is moved downward, and the rotating strap 5 causes the rotating frame 4 to rotate counterclockwise. The counterclockwise rotating rotating frame 4 uses the teeth 401 to make the sliding frame 16 move up on the surface of the inner block 17 until the strap 5 reaches the fitting position. The plug-in portion cooperates with the notch 19 to lock the sliding frame 16, preventing the rotating frame 4 from continuing to rotate, making it convenient for the user to adjust the position of the strap 5 according to his own habits.

[0034] The plug-in portion includes: an insert plate 20, a bottom frame 21, a protruding plate 22, a limiting rod 23, and a second elastic member 24, which is configured as a spring. The bottom frame 21 is fixed to the bottom of the front side of the sliding frame 16, and the rear end of the insert plate 20 is inserted into the interior of the bottom frame 21. A protruding plate 22 is fixed to the rear end of the insert plate 20, and the rear end of the protruding plate 22 is engaged within the interior of the notch 19. A limiting plate is provided at the top of the front end of the insert plate 20, and a limiting rod 23 passes through the limiting plate. The rear end of the limiting rod 23 is connected to the sliding frame 16. The second elastic member 24 is sleeved on the surface of the limiting rod 23. The front end of the second elastic member 24 is connected to the limiting plate, and the rear end of the second elastic member 24 is connected to the sliding frame 16. The top of the inner portion of the notch 19 is provided with a second inclined surface 191, and the top surface of the rear end of the protruding plate 22 is provided with a chamfered surface corresponding to the second inclined surface 191. When the rotating frame 4 rotates counterclockwise, the counterclockwise rotating rotating frame 4 uses the teeth 401 to move the sliding frame 16 upward, and the upward sliding frame 16 uses the bottom frame 21 to move the inserting plate 20 upward. At this time, the chamfered surface of the protruding plate 22 slides on the second inclined surface 191 of the notch 19, and the sliding protruding plate 22 gradually moves out of the inside of the notch 19. The moved protruding plate 22 makes the inserting plate 20 move away from the vertical rod 18, and the inserting plate 20 drives the limiting plate to move forward on the surface of the limiting rod 23. The limiting plate pulls the second elastic member 24 on the surface of the limiting rod 23, and the second elastic member 24 makes the rear end face of the protruding plate 22 fit with the outer circumferential surface of the vertical rod 18. The upward sliding frame 16 makes the protruding plate 22 move up on the surface of the vertical rod 18 until the protruding plate 22 corresponds to the notch 19, and the elastic force of the second elastic member 24 makes the rear end of the protruding plate 22 inserted into the inside of the notch 19.

[0035] By rotating the rotating frame 4 counterclockwise, the teeth 401 cooperate with the tooth grooves 161 to make the sliding frame 16 continue to move upward. At this time, the elastic force of the second elastic member 24 makes the convex plate 22 correspondingly snap into the inside of the adaptive notch 19, making it convenient for the user to adjust the position of the strap 5 according to his own habits.

[0036] When the rotating frame 4 rotates clockwise, the bottom of the notch 19 blocks the protruding plate 22 from moving out of the notch 19, thereby preventing the rotating frame 4 from rotating clockwise and thus preventing the rotating frame 4 from moving randomly. When the rotating frame 4 needs to be rotated clockwise, the inserting plate 20 is pulled away from the vertical rod 18. The moving inserting plate 20 pulls the protruding plate 22 out of the notch 19, and the rotating frame 4 can now rotate clockwise.

[0037] Working principle of the present invention:

[0038] Reference Figures 1 to 8 As shown, before the user wears the body 1, he pulls the pin plate 3 backward, and the pin plate 3 moving backward inside the side groove 101 pulls the two movable plates 6 to move backward synchronously, and the moving pin plate 3 causes the side tube 10 to move backward inside the slide groove 102 until the side tube 10 is at the rear side of the slide groove 102. At this time, the distance that the pin plate 3 is pulled out of the side groove 101 is the longest, and the strap 5 is farthest from the body 1.

[0039] Align the rear side of the body 1 with the user's eyes, push the pin plate 3 forward, and the forward-moving pin plate 3 moves forward inside the side groove 101. The forward-moving pin plate 3 drives the side tube 10 to move forward inside the slide groove 102 until the strap 5 fits against the back of the user's head. At this time, rotate the rotating sleeve 11. Since the insertion rod 7 is spirally inserted into the side tube 10, the rotating rotating sleeve 11 causes the insertion rod 7 to rotate inside the side tube 10. The rotating insertion rod 7 gradually enters the inner groove of the pin plate 3, and the inner end of the rotating insertion rod 7 gradually squeezes the first inclined portion of the movable plate 6. Surface 601, the pressure of the insertion rod 7 on the first inclined surface 601 causes the movable plate 6 to move inside the inner groove. At this time, the two movable plates 6 are separated from each other, and the movable plate 6 moves on the surface of the inner rod 8 using the movable groove. At this time, the two relative movable plates 6 are separated from each other, and the moving movable plate 6 cooperates to pull the first elastic member 9, and the outer end of the movable plate 6 moves out of the inner groove until the outer end of the top movable plate 6 squeezes the top of the side groove 101, and the outer end of the bottom movable plate 6 squeezes the bottom of the side groove 101. At this time, the inner surface of the rotating sleeve 11 is in contact with the end face of the body 1.

[0040] By squeezing and fitting the outer end of the movable plate 6 with the side groove 101, the movable plate 6 is prevented from moving freely inside the side groove 101, and the rotating sleeve 11 is tightly fitted with the end face of the body 1, so as to prevent the pin plate 3 from moving freely inside the side groove 101, thereby facilitating the fit of the strap 5 with the back of the user's head, ensuring that the body 1 is sleeved on the user's brain, and the restriction of the pin plate 3 by the movable parts facilitates the entire body 1 to adapt to the brains of different users.

[0041] Align the rear side of the body 1 with the user's eyes, push the pin plate 3 forward, and the forward-moving pin plate 3 moves forward inside the side groove 101. The forward-moving pin plate 3 drives the side tube 10 to move forward inside the slide groove 102 until the strap 5 fits against the back of the user's head. At this time, rotate the rotating sleeve 11. Since the insertion rod 7 is spirally inserted into the side tube 10, the rotating rotating sleeve 11 causes the insertion rod 7 to rotate inside the side tube 10. The rotating insertion rod 7 gradually enters the inner groove of the pin plate 3, and the inner end of the rotating insertion rod 7 gradually squeezes the first inclined portion of the movable plate 6. Surface 601, the pressure of the insertion rod 7 on the first inclined surface 601 causes the movable plate 6 to move inside the inner groove. At this time, the two movable plates 6 are separated from each other, and the movable plate 6 moves on the surface of the inner rod 8 using the movable groove. At this time, the two relative movable plates 6 are separated from each other, and the moving movable plate 6 cooperates to pull the first elastic member 9, and the outer end of the movable plate 6 moves out of the inner groove until the outer end of the top movable plate 6 squeezes the top of the side groove 101, and the outer end of the bottom movable plate 6 squeezes the bottom of the side groove 101. At this time, the inner surface of the rotating sleeve 11 is in contact with the end face of the body 1.

[0042] By squeezing and fitting the outer end of the movable plate 6 with the side groove 101, the movable plate 6 is prevented from moving freely inside the side groove 101, and the rotating sleeve 11 is tightly fitted with the end face of the body 1, so as to prevent the pin plate 3 from moving freely inside the side groove 101, thereby facilitating the fit of the strap 5 with the back of the user's head, ensuring that the body 1 is sleeved on the user's brain, and the restriction of the pin plate 3 by the movable parts facilitates the entire body 1 to adapt to the brains of different users.

[0043] When the rotating frame 4 rotates counterclockwise, the counterclockwise rotating rotating frame 4 uses the teeth 401 to move the sliding frame 16 upward, and the upward sliding frame 16 uses the bottom frame 21 to move the inserting plate 20 upward. At this time, the chamfered surface of the protruding plate 22 slides on the second inclined surface 191 of the notch 19, and the sliding protruding plate 22 gradually moves out of the inside of the notch 19. The moved protruding plate 22 makes the inserting plate 20 move away from the vertical rod 18, and the inserting plate 20 drives the limiting plate to move forward on the surface of the limiting rod 23. The limiting plate pulls the second elastic member 24 on the surface of the limiting rod 23, and the second elastic member 24 makes the rear end face of the protruding plate 22 fit with the outer circumferential surface of the vertical rod 18. The upward sliding frame 16 makes the protruding plate 22 move up on the surface of the vertical rod 18 until the protruding plate 22 corresponds to the notch 19, and the elastic force of the second elastic member 24 makes the rear end of the protruding plate 22 inserted into the inside of the notch 19.

[0044] By rotating the rotating frame 4 counterclockwise, the teeth 401 cooperate with the tooth grooves 161 to make the sliding frame 16 continue to move upward. At this time, the elastic force of the second elastic member 24 makes the convex plate 22 correspondingly snap into the inside of the adaptive notch 19, making it convenient for the user to adjust the position of the strap 5 according to his own habits.

[0045] When the rotating frame 4 needs to be rotated clockwise, the insert plate 20 is pulled away from the vertical rod 18. The moving insert plate 20 pulls the protruding plate 22 out of the notch 19, and the rotating frame 4 can now rotate clockwise. The clockwise rotating rotating frame 4 drives the multiple teeth 401 to rotate. Since the teeth 401 correspond to the tooth grooves 161, the rotating rotating frame 4 uses the multiple teeth 401 to make the slide frame 16 move down on the inner block 17. The downwardly moving slide frame 16 moves down on the surface of the vertical rod 18 until the strap 5 rotates to the appropriate position. The rotating frame 4 stops rotating. At this time, the plug-in part cooperates with the notch 19 to complete the restriction of the rotating frame 4, preventing the rotating frame 4 from being swayed at the rear end of the pin plate 3.

[0046] The user can rotate it at will to facilitate the user to automatically adjust the position of the strap 5.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
