[0001] The present invention relates to the technical field of remote education AR tools, and in particular to an AR-assisted teaching tool for remote education. Background Art

[0002] With the development of educational technology, AR technology, which has emerged in recent years, is gradually becoming a new favorite for assisted learning. The integration and application of AR technology not only reshapes the way of knowledge transmission, but also opens a new chapter of immersive smart classrooms, allowing students' learning experience to leap to an unprecedented height. Distance education can use AR technology to enhance the sense of participation and improve the effect of in-person learning.

[0003] At present, AR technology is mainly used with AR glasses. However, because the current AR glasses integrate multiple display screens, processing units and power supply units, their mass is very large, which causes people to have a serious burden after wearing them for a long time, greatly hindering the development of AR distance learning. Therefore, they need to be used with the help of an external suspension mechanism. However, the existing external suspension mechanism simply plays a suspension function, but cannot automatically adjust the displacement according to the wearer's head movement. This makes its functionality and practicality very simple, and also greatly reduces the limitations and comfort of wearing. Summary of the invention

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4An AR-assisted teaching tool for distance education shown in the figure comprises a longitudinal assembly tube 1 and AR glasses 2 for distance education, wherein a lateral mounting clamp arm 4 is fixedly mounted on the outer side of the longitudinal assembly tube 1 through a lateral tightening device 3, a detachable top suspension arm 5 of an inverted L-shaped structure is fixedly mounted on the upper end of the longitudinal assembly tube 1, a top mounted electric control seat 6 is fixedly mounted on the outer end of the top suspension arm 5, an arc-shaped assembly cover 7 is fixedly mounted on the outer side of the AR glasses 2, both ends of the arc-shaped assembly cover 7 are worn on the user's head through elastic bands, three flexible slings 8 are passed through the upper end of the arc-shaped assembly cover 7, a top tape reel seat 9 matching the top mounted electric control seat 6 is installed on the upper end of the flexible sling 8, and a gravity sensor controller 10 for controlling the top mounted electric control seat 6 is fixedly mounted on the side wall of the arc-shaped assembly cover 7 located above the AR glasses 2.

[0024] Working principle: People sit on the seat, then plug the top tape reel seat 9 into the top mounted electric control seat 6, use the top boom 5 to hoist the entire device, and then use the gravity sensor controller 10 and the pulling force on the flexible sling 8 to cooperate with each other, so as to freely control the retraction and extension of the flexible sling 8 for different children, thereby ensuring the basic hoisting force, so as to ensure the purpose of zero pressure.

[0025] In order to cooperate with clamping and fixing, the laterally installed clamp arm 4 includes a lateral assembly frame 41 fixed on one side of the lateral tightening device 3, a first clamp arm frame 42 movably assembled on the assembly surface of the lateral assembly frame 41, a second clamp arm frame 43, an internally threaded locking sleeve 44 movably installed on the first clamp arm frame 42, and a locking bolt 45 movably installed on the second clamp arm frame 43 and cooperating with the internally threaded locking sleeve 44.

[0026] The locking bolt 45 is threadedly installed in the internal thread locking sleeve 44 on the first clamp arm frame 42. By rotating the locking bolt 45, the first clamp arm frame 42 and the second clamp arm frame 43 are controlled to approach each other, and then fixed to the backrest or seat plate by clamping.

[0027] In order to cooperate with top installation and adjustment, the top mounted electric control seat 6 includes an end mounting cover 61 fixed to the outer end of the top boom 5, a worm gear assembly 62 fixedly mounted on the top of the end mounting cover 61, and an adjusting motor 63 for controlling the worm gear assembly 62.

[0028] The adjusting motor 63 controls the rotation of the longitudinal control shaft 92 through the worm gear assembly 62 .

[0029] In order to facilitate assembly and adjustment, the top tape reel 9 includes a top assembly box 91 that cooperates with the end assembly cover 61, a first tape reel 93, a second tape reel 94 and a third tape reel 95 that are movably installed inside the top assembly box 91 through a longitudinal control shaft 92.

[0030] The first belt reel 93, the second belt reel 94 and the third belt reel 95 are all provided with longitudinally connected transition through holes at their centers at the longitudinal assembly ends.

[0031] In order to cooperate with the extension and retraction of the flexible tape 8, strip guide openings are provided on the side wall of the top assembly box 91 at positions corresponding to the first tape reel 93, the second tape reel 94 and the third tape reel 95.

[0032] The inner ends of the three flexible tapes 8 are respectively wound around the outside of the first tape reel 93 , the second tape reel 94 and the third tape reel 95 , and the outer ends pass through the strip guide opening to be connected to the arc-shaped assembly cover 7 .

[0033] In order to coordinate the measurement of the AR glasses 2 and the horizontal position, and thus coordinate the adjustment, the gravity sensor controller 10 includes an inner detection seat 101 fixed on the side wall of the arc-shaped assembly cover 7 and an electronic level controller module 102 fixed inside the inner detection seat 101.

[0034] The electronic level controller module 102 measures the angle when people wear the sling by monitoring the horizontal position, and adjusts the length of the flexible sling 8 at different positions. In this way, there is always zero pressure.

[0035] In order to facilitate loading and unloading, a lateral limiting hole 64 is opened on the inner side of the end assembly cover 61, and a telescopic lateral limiting block 96 is elastically mounted on the outer side of the top assembly box 91.

[0036] The top assembly box 91 is inserted into the end assembly housing 61 from the lower end opening of the end assembly housing 61 , and then the telescopic lateral limiting block 96 is inserted into the lateral limiting hole 64 for fixed assembly.

[0037] The telescopic lateral limiting block 96 is elastically assembled in the mounting groove on the outer side surface of the top assembly box 91 by an extrusion spring.

[0038] In order to cooperate with the control, the upper end of the arc-shaped assembly cover 7 is located at the assembly end of the flexible sling 8 and has an upwardly protruding top hanging frame 11, and a built-in pressure control unit 12 is fixedly installed on the inner top surface of the top hanging frame 11.

[0039] The flexible sling 8 is conveniently connected through the top lifting frame 11, and the pulling force of the flexible sling 8 is used to touch the built-in pressure control unit 12. The built-in tension control unit 12 is used to control the engagement state of the embedded magnetic control lock block 97 and the longitudinal control shaft 92, and the flexible sling 8 is retracted and released by rotation; when the built-in pressure control unit 12 cannot receive the pressure value, the winding operation is performed, and the winding and unwinding operations are completed by controlling the forward and reverse rotation of the first belt reel 93, the second belt reel 94 and the third belt reel 95.

[0040] First, after people finish wearing, they press the preset button on the outside of the arc-shaped assembly cover 7, and then the built-in pressure control unit 12 performs a reeling operation according to the pressure size and adjusts to an optimal wearing position. Then, the pressure of the built-in pressure control unit 12 at each position after the setting is completed is recorded, and this is used as a reference. Then, the preset button is released to complete the setting. In this way, when people turn their heads, raise their heads, and lower their heads, the flexible strap 8 will be pulled due to the transfer of the arc-shaped assembly cover 7. At this time, the flexible strap 8 will squeeze the built-in tension control unit 12, and then when the pressure exceeds the reference value, the unwinding operation starts; when the pressure is small and lower than the reference value, the rewinding operation starts.

[0041] In order to facilitate adjustment, the worm gear assembly 62 includes a transverse worm wheel 621 movably mounted on the top of the end assembly cover 61 and a transverse worm 622 meshing with the transverse worm wheel 621. The upper end of the longitudinal control shaft 92 is inserted into the central axis hole of the transverse worm wheel 621 through the control shaft and axially assembled with the transverse worm wheel 621.

[0042] The adjusting shaft of the adjusting motor 63 is inserted into the transverse worm 622 and fixedly assembled axially. The adjusting motor 63 drives the transverse worm wheel 621 to rotate by controlling the rotation of the transverse worm 622, and then the transverse worm wheel 621 controls the longitudinal control shaft 92 to rotate synchronously.

[0043] In order to coordinate separation and engagement, embedded magnetic lock blocks 97 are installed on the inner arc surfaces of the first belt reel 93, the second belt reel 94 and the third belt reel 95, and an annular tooth groove 98 cooperating with the embedded magnetic lock block 97 is opened on the outer arc surface of the longitudinal control shaft 92.

[0044] The first belt reel 93, the second belt reel 94 and the third belt reel 95 are all provided with inner telescopic grooves for assembling embedded magnetic control locking blocks 97 on their inner arc surfaces. The embedded magnetic control locking blocks 97 include a guide shaft with a limit block at the end fixed on the inner wall of the inner telescopic groove, a telescopic block slidably sleeved on the guide shaft, an extrusion spring located on the outer side of the guide shaft inside the telescopic block, and an electromagnet fixed on the side wall of the limit block. The electromagnet is started to control the extrusion spring to pull the telescopic block, and the telescopic block slides along the guide shaft and extends to the opening position of the inner telescopic groove, so that the tooth surface of the telescopic block is inserted into the annular tooth groove 98, completing the meshing and fixation with the longitudinal control shaft 92, so that the longitudinal control shaft 92 can drive the first belt reel 93, the second belt reel 94 and the third belt reel 95 to rotate.

[0045] When idle, the embedded limiting arms on the outer side of the telescopic block extend outward along the slide grooves on the inner top surfaces of the first belt reel 93, the second belt reel 94 and the third belt reel 95, and are inserted into the annular positioning grooves on the inner wall of the top assembly box 91 to complete the angle locking.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
