[0030] This embodiment provides a head-mounted intelligent display device, specifically Figures 1-4 、 Figures 8-11 As shown, a head-mounted intelligent display device includes a display device 101, a horizontal strap 102, and a longitudinal strap 103. The two ends of the horizontal strap 102 are detachably connected to the two ends of the display device 101 respectively, and one end of the longitudinal strap 103 is connected to the display device 101, and the other end is connected to the horizontal strap 102. It is characterized in that: a lens mounting assembly 2 is detachably mounted on the display device 101, and the lens mounting assembly 2 includes two groups of symmetrically arranged adjustment frames 21, mounting frames 22, and viewing lenses 23. The mounting frame 22 is pluggable and installed on the adjustment frame 21, and the viewing lenses 23 are detachably mounted between the mounting frame 22 and the adjustment frame 21.

[0031] The adjusting frame 21 comprises an adjusting frame body 2101, a first observation hole is arranged on the adjusting frame body 2101, a push block 2102 is slidably connected on the adjusting frame body 2101, and the push block 2102 and the adjusting frame body 2101 are provided with a push block spring 2103; the mounting frame 22 comprises a mounting frame body 2201, a second observation hole is arranged on the mounting frame body 2201, a limiting ring 2203 is rotatably connected on the mounting frame body 2201, a driven push rod 2206 and a plurality of limiting sliding grooves 2207 are arranged on the limiting ring 2203, a plurality of limiting push rods 2202 are slidably connected on the mounting frame body 2201, the limiting push rods 2202 slide in the limiting sliding grooves 2207, and the push block 2102 and the driven push rod 2206 form cooperation.

[0032] The adjusting frame 21 is fixed on the display device 101 by means of a screw, then the viewing lens 23 is placed in the second observation hole of the mounting frame 22, at this time, the plurality of limiting push rods 2202 support the viewing lens 23, then the mounting frame 22 is inserted into the slot formed by the adjusting frame 21 and the display device 101, when the mounting frame 22 is inserted by half, the push block 2102 begins to contact the driven push rod 2206, at this time, the push block 2102 begins to push the driven push rod 2206 to make the limiting ring 2203 rotate, the rotation of the limiting ring 2203 makes the limiting sliding grooves 2207 rotate synchronously, when the limiting sliding grooves 2207 rotate, the plurality of limiting push rods 2202 are synchronously further contracted along the radial direction of the second observation hole, at this time, the end of the limiting push rod 2202 begins to extrude the viewing lens 23, so that the viewing lens 23 is close to the adjusting frame body 2101, when the viewing lens 23 extrudes the adjusting frame body 2101, the limiting ring 2203 cannot continue to rotate, at this time, with the insertion of the mounting frame 22, the push block spring 2103 begins to be compressed, so that the push block 2102 always extrudes the driven push rod 2206, ensuring that the viewing lens 23 is completely limited, preventing the viewing lens 23 from shaking when used by the user; when there is a stain on the viewing lens 23 and it needs to be taken out for cleaning or the user needs to change the viewing lens 23, the user pulls out the mounting frame 22, at this time, with the pulling out of the mounting frame 22, the push block 2102 no longer extrudes the driven push rod 2206, so the limiting push rod 2202 also does not extrude the viewing lens 23, the limiting push rod 2202 slightly protruding from the second observation hole only supports the viewing lens 23, and then is completely taken out.

[0033] Through the above settings, since the user can choose the viewing lens 23 of the corresponding degree according to the degree of his eyes, and since the thickness of the viewing lenses 23 of different degrees is slightly different, the push block spring 2103 is used in conjunction with the limiting push rod 2202 to achieve complete limiting of the viewing lenses 23 of different degrees to prevent the viewing lenses 23 from moving abnormally; and the limiting action is automatically completed when the mounting frame 22 is inserted into the adjustment frame 21, without the need for manual operation, to avoid fingerprints and other dirt left on the viewing lenses 23 during operation by the user, affecting the viewing effect; and the detachable viewing lenses 23 can also be conveniently used for daily cleaning of the viewing lenses 23.

[0034] Example 2:

[0035] This embodiment is further expanded on the basis of the above embodiment. Figures 4-7 As shown, the adjusting frame 2101 is provided with a locking unit, which includes a locking block 2105 slidably connected to the adjusting frame 2101, a locking spring 2104 is provided between the locking block 2105 and the adjusting frame 2101, and a locking slide is provided on the locking block 2105. The locking slide is connected end to end by a first slide 2109, a second slide 2110, and a third slide 2111. The locking block 2105 is rotated to connect the hook 2108, and the locking block 2105 is engaged. A slope 2107 is provided; a locking rod 2106 is installed on the adjustment frame 2101, one end of the locking rod 2106 slides in the locking groove, and a matching slot 2112 is provided on the installation frame 2201, and the hook 2108 slides in the matching slot 2112; a first locking slot 2204 and a second locking slot 2205 are provided on the installation frame 2201, the first locking slot 2204 is matched with the hook 2108, and the second locking slot 2205 is matched with the inclined surface 2107.

[0036] Since the depth of the first chute 2109 is greater than that of the third chute 2111, and the eccentric "M" shaped slideway on the second chute 2110 (see the attached Figure 5 As shown), the sliding of the engaging rod 2106 on the engaging groove is always a one-way cycle, that is, sliding from the first groove 2109 to the second groove 2110, and then sliding to the third groove 2111, and finally returning to the first groove 2109, and so on.

[0037] When the mounting frame 22 is inserted into the adjusting frame 21, the second engaging groove 2205 first contacts and squeezes the inclined surface 2107. At this time, the hook 2108 is in the deeper area of ​​the matching engaging groove 2112. Therefore, the hook 2108 will not block the mounting frame 2201. The second engaging groove 2205 pushes the inclined surface 2107 to stretch the engaging spring 2104. At this time, the engaging rod 2106 slides from the first sliding groove 2109 to the first peak point on the second sliding groove 2110. At the same time, the engaging block 2105 drives the hook 2108 to slide. When the hook 21 When 08 is in the shallow area of ​​the matching slot 2112, the hook 2108 will be stuck in the first engaging slot 2204, and then the installation frame 22 will be released. At this time, under the pulling force of the engaging spring 2104, the engaging rod 2106 slides to the valley point on the second slide slot 2110, and the engaging block 2105 is stabilized there. At this time, the installation frame 2201 is flush with the end of the adjustment frame 2101. Since the hook 2108 is embedded in the first engaging slot 2204, the installation frame 22 cannot be directly pulled out of the adjustment frame 21; at this time, the user can watch the movie.

[0038] When the installation frame 22 needs to be pulled out of the adjustment frame 21, first press the installation frame 22. At this time, the engaging rod 2106 slides to the second peak point of the second slide groove 2110, and then release the installation frame 22. Under the action of the engaging spring 2104, the engaging block 2105 begins to move, and the engaging rod 2106 begins to slide into the third slide groove 2111. At this time, the hook 2108 begins to slide into the deeper area on the matching slot 2112, that is, the hook 2108 begins to move away from the first engaging slot 2204, so that the installation frame 2201 is not limited by the hook 2108. At this time, the installation frame 22 can be taken out.

[0039] Through the above arrangement, the installation frame 22 can be stably installed on the adjustment frame 21, and there will be no situation where the installation frame 22 slides out of the adjustment frame 21 due to accidental touch by a person, thereby improving the stability of equipment operation.

[0040] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0041] Example 3:

[0042] This embodiment is further expanded on the basis of the above embodiment. Figure 4 、 Figure 8 As shown, a stepped circular groove is provided on one side of the adjustment frame 2101 close to the mounting frame 22 , a gasket 2113 is installed in the stepped circular groove, and a gasket 2113 is provided on the contact surface between the limiting push rod 2202 and the viewing lens 23 .

[0043] The provided gasket 2113 provides buffering protection for the viewing lens 23 to prevent the edge of the viewing lens 23 from breaking, and also serves as a seal to prevent dust, tears or other liquids from entering the body from here.

[0044] Other parts of the embodiment are the same as the above-described embodiments, and will not be described again.

[0045] Embodiment 4:

[0046] The embodiment is further extended on the basis of the above-described embodiments, and the diameter of the first observation hole is smaller than the diameter of the second observation hole.

[0047] Since the user's line of sight first passes through the first observation hole and then passes through the second observation hole when watching the movie, the limiting push rod 2202 is shielded by the adjusting frame 2101, so that the user will not see the limiting push rod 2202 when watching the movie, improving the user experience.

[0048] Other parts of the embodiment are the same as the above-described embodiments, and will not be described again.

[0049] Embodiment 5:

[0050] The embodiment is further extended on the basis of the above-described embodiments, and the movie watching lens 23 is any one of a plane mirror, a concave mirror, and a convex mirror. Through the setting, the product can be used by normal vision, myopia, and hypermetropia crowds, and the application range is wider.

[0051] Other parts of the embodiment are the same as the above-described embodiments, and will not be described again.

[0052] Embodiment 6:

[0053] The embodiment is further extended on the basis of the above-described embodiments, and the adjusting frame 21 is slidingly connected to the display device 101.
