Description

Technical Field

[0001] This invention belongs to the field of head-mounted smart VR glasses technology, specifically, it relates to a digital remote intelligent interactive teaching device. Background Technology

[0002] VR is an abbreviation for Virtual Reality. The concept was proposed in the 1980s. Specifically, it refers to a new human-computer interaction method created with the help of computers and the latest sensor technology. Its display principle is that the left and right eye images are displayed on the screens for the left and right eyes respectively. After the human eye obtains this information with differences, it generates a three-dimensional feeling in the mind.

[0003] VR technology is gradually being applied in teaching. It can present textbook content to students more intuitively, providing more information than traditional classrooms, making it easier for students to build a systematic knowledge base, and stimulating their divergent thinking.

[0004] Announcement No. CN221406188U discloses a VR teaching glasses with an anti-fall-off structure, including a VR glasses body. A headband is fixedly connected to the outer wall of the VR glasses body. Two top straps are fixedly connected to the upper surface of the VR glasses body, and the other ends of the two top straps are fixedly connected to the headband. Sleeves are fixedly connected to both ends of the headband. U-shaped frames are slidably connected inside the two sleeves. Ratchets are provided on the front ends of both sides of the U-shaped frames. A connecting shaft is fixedly connected to both ends of the two sleeves. A baffle matching the ratchet is rotatably connected to the outer wall of the two connecting shafts. A connecting rod is slidably connected to the front ends of the two sleeves. One end of the baffle abuts against the ratchet, and the other end of the baffle abuts against the connecting rod. Through the baffle and the ratchet, the U-shaped frame can only move upward in one direction without external force, thus fixing the headband to the user's head.

[0005] While these educational glasses can improve stability, with the development of VR technology, the content of VR teaching is also increasing. For example, using VR to learn Tai Chi, dance, and aerobics involves a large range of head movement during the learning process. Since the overall weight of the VR glasses is located on the face, it indirectly exerts tensile stress on the cervical spine. In order to maintain the balance of the head, the neck muscles will continuously contract and exert force to counteract the forward gravitational torque of the glasses. The muscles on the back of the neck will be in a state of tension for a long time, resulting in continuous tensile stress on the cervical spine. In the long run, this may induce straightening of the physiological curvature of the cervical spine or muscle strain. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] To address the issue raised in the background art that the overall weight of VR glasses is located on the face, indirectly causing tensile stress on the cervical spine, and that the neck muscles continuously contract and exert force to maintain head balance and counteract the forward gravitational torque of the glasses, resulting in the posterior neck muscles being in a state of tension for a long time, leading to continuous tensile stress on the cervical spine, which may eventually induce straightening of the cervical spine's physiological curvature or muscle strain, the present invention adopts the following technical solution.

[0008] A digital remote intelligent interactive teaching device includes a VR teaching glasses main body for displaying teaching content. A binding part is installed on the VR teaching glasses main body to bind it to the user's head. A connecting strap is fixedly connected to the binding part, and a wearing part is connected to the end of the connecting strap. An adjustment component is installed on the connecting strap to adjust the length and tension of the connecting strap. The tension generated by the connecting strap is less than or equal to the tensile stress exerted on the neck by the VR teaching glasses main body. The connecting strap generates a pulling force towards the back of the neck, which counteracts the indirect tensile stress exerted on the neck by the weight of the VR teaching glasses main body itself.

[0009] Preferably, the connecting strap is an elastic band, and there are two connecting straps, with the two connecting straps symmetrically connected to the outer wall of the wearable part.

[0010] Preferably, the adjustment component includes an adjustment buckle, which is installed on the connecting belt. The adjustment buckle adjusts the elongation of the connecting belt, shortening the elongation when the tension is too high and lengthening the elongation when the tension is too low.

[0011] Preferably, the connecting strap is a flexible connecting strap, and a tension part is installed on the back of the wearable part. The connecting strap is inserted into the interior of the tension part, and the tension part causes the connecting strap to elastically stretch, so that the connecting strap generates tension.

[0012] Preferably, the tension part includes a mounting housing, which is hollow inside and has an opening at the top. Guide rollers are rotatably connected to the two sides inside the opening. The connecting belt passes between the two guide rollers. Sliding rods are detachably connected to the two sides inside the mounting housing. A limiting part is fixedly connected to the bottom of the connecting belt. The limiting part is slidably connected to the outer wall of the sliding rods on both sides. A tension spring is sleeved on the outer wall of the sliding rod above the limiting part. The elastic force of the tension spring drives the limiting part to move downward, so that the connecting belt is tightened and a tension is generated. When the user lowers his head, the limiting part moves upward and compresses the tension spring.

[0013] Preferably, two connecting strips and tension sections are provided, with the tension sections and connecting strips symmetrically arranged on both sides.

[0014] Preferably, adjusting pressure plates are slidably connected to the outer walls of the sliding rods inside the two mounting housings on both sides. The adjusting pressure plates are located at the upper end of the tension spring. Adjusting parts are provided on the outside of the two mounting housings on both sides, and the adjusting parts drive the adjusting pressure plates inside the two mounting housings on both sides to move upward or downward.

[0015] Preferably, the outer wall of the mounting housing is provided with a sliding groove, and the adjusting part includes a connecting plate. The two ends of the connecting plate pass through the sliding groove on the two sides of the mounting housing and are detachably connected to the outer wall of the adjusting pressure plate. The adjusting part is located on the outer wall between the two sides of the mounting housing and is fixedly connected to an adjusting plate. The upper and lower sides of the two sides of the mounting housing are detachably connected to mounting horizontal plates. Adjusting screws are rotatably connected to the mounting horizontal plates on both sides. The adjusting plate is threadedly connected to the outer wall of the adjusting screw. Adjusting knobs are detachably connected to both ends of the adjusting screw. Rotating the adjusting knob on either side drives the adjusting screw to rotate, which causes the adjusting plate to move up or down on the outer wall of the adjusting screw, driving the adjusting pressure plate to move up and down along the outer wall of the sliding rod, and adjusting the contraction of the tension spring to adjust the tension of the connecting belt.

[0016] Preferably, a protective vertical plate is detachably connected between the horizontal plates on both sides, and the protective vertical plate passes through the adjustment plate.

[0017] Preferably, the adjusting buckle is a miniature ratchet adjusting buckle or a spring-pressing buckle.

[0018] Compared to existing technologies, the advantages of this invention are as follows: the pulling force generated by the connecting strap or the tension part towards the back of the neck can effectively counteract the indirect tensile stress on the neck caused by the weight of the VR teaching glasses themselves, reducing the stress on the neck. When the head is lowered, the pulling force can dynamically counteract the increased load caused by the weight of the glasses, further reducing the burden on the neck. When the head is tilted back, the pulling force naturally weakens and will not cause additional pulling. The tension can be adjusted according to the user's different neck length and height by adjusting the buckle or the adjustment part. The symmetrically arranged connecting strap and tension part make the tension distribution more balanced and will not cause the head to tilt. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments. Example 1

[0024] like Figure 1-3The diagram shown is a schematic representation of a preferred embodiment of a digital remote intelligent interactive teaching device according to the present invention. This embodiment of the digital remote intelligent interactive teaching device includes a VR teaching glasses main body 100, which is used to display teaching content. A binding part 101 is installed on the VR teaching glasses main body 100, binding the VR teaching glasses main body 100 to the user's head. A connecting strap 201 is fixedly connected to the binding part 101, and a wearing part 200 is connected to the end of the connecting strap 201. The connecting strap 201 is an elastic band, and the tensile force generated by the connecting strap 201 is less than or equal to that of the VR teaching glasses main body 100. Regarding the tensile stress on the neck, in this embodiment, during use, the VR teaching glasses main body 100 is first fixed to the user's face by the binding part 101, and then the wearing part 200 is put on. Through the setting of the connecting strap 201, a pulling force can be generated towards the back of the neck. The pulling force will offset the indirect tensile stress on the neck caused by the weight of the VR teaching glasses main body 100 itself. In this way, the stress load on the neck can be reduced when using the VR teaching glasses main body 100 for a long time. When it is necessary to lower the head, the pulling force will offset the weight of the VR teaching glasses main body 100, reducing the stress load on the neck. When it is necessary to tilt the head back, the pulling force of the connecting strap 201 will weaken accordingly.

[0025] Because neck and head lengths vary from person to person, the initial elongation of the connecting strap 201 is greater for users with longer necks, leading to increased tension and potentially increasing neck pressure. Conversely, the initial elongation of the connecting strap 201 is smaller for users with shorter necks, resulting in insufficient tension or inadequate support for neck pressure. Therefore, to ensure that the connecting strap 201 provides balanced tension for users of different heights, a specific structure could be adopted as follows: Figure 4 In the embodiment shown, an adjustment buckle 202 is installed on the connecting strap 201. The adjustment buckle 202 is a miniature ratchet adjustment buckle or a spring-press buckle. In this embodiment, the extension of the connecting strap 201 can be adjusted according to the specific situation by adjusting the buckle 202. When the tension is too high, the extension of the connecting strap 201 is shortened, and when the tension is too low, the extension of the connecting strap 201 is lengthened. In this way, the tension can be adjusted according to the body's feeling, thereby relieving the stress load on the neck.

[0026] In order to make the generated tension more balanced, two connecting straps 201 are provided, and the two connecting straps 201 are symmetrically connected to the outer wall of the wearable part 200. Example 2

[0027] like Figure 4As shown, this is another preferred embodiment of the invention. The difference between this embodiment and embodiment 1 is that the connecting strap 201 is a flexible connecting strap, and a tension part 300 is installed on the back of the wearing part 200. The connecting strap 201 is inserted into the interior of the tension part 300, and the tension part 300 causes the connecting strap 201 to be elastically stretched. In this embodiment, by setting the tension part 300, the connecting strap 201 can produce an elastic effect similar to an elastic band, thereby generating tension to offset the tensile stress applied to the neck by the VR teaching glasses main body 100, thereby achieving another way to protect the neck.

[0028] The specific structure of the tension section 300 can be adopted as follows: Figure 5 In the embodiment shown, the tension part 300 includes a mounting housing 301. The mounting housing 301 is hollow inside and has an opening at the top. Guide rollers 302 are rotatably connected to the two sides inside the opening. The connecting belt 201 passes between the two guide rollers 302. Sliding rods 303 are detachably connected to the two sides inside the mounting housing 301. A limiting part 203 is fixedly connected to the bottom of the connecting belt 201. The limiting part 203 is slidably connected to the outer wall of the two sliding rods 303. A tension spring 304 is sleeved on the outer wall of the sliding rod 303 above the limiting part 203. In this embodiment, the tension spring 304 drives the limiting part 203 to move downward, thereby making the connecting belt 201 taut and generating tension. When it is necessary to lower the head during learning, the limiting part 203 moves upward and compresses the tension spring 304, thereby resisting the tensile stress generated on the neck by the gravity of the VR teaching glasses body 100.

[0029] In order to make the generated tension more balanced, two connecting straps 201 and two tension parts 300 are provided, with the tension parts 300 and connecting straps 201 arranged symmetrically on both sides.

[0030] Since the downward elastic force generated by the tension spring 304 is fixed, it is impossible to adjust the elastic force generated by the tension spring 304 according to the different weights of the VR teaching glasses main body 100. In order to adjust the elastic force of the tension spring 304 according to the different weights of the VR teaching glasses main body 100, the specific structure can be as follows: Figure 6In the embodiment shown, adjusting pressure plates 305 are slidably connected to the outer walls of the sliding rods 303 inside the two side mounting housings 301. The outer wall of the mounting housing 301 is provided with a sliding groove 306. The adjusting pressure plates 305 are located at the upper end of the tension spring 304. Adjusting parts 400 are provided on the outside of the two side mounting housings 301. The adjusting parts 400 drive the adjusting pressure plates 305 inside the two side mounting housings 301 to move upward or downward. In this embodiment, the adjusting pressure plates 305 can be moved downward by the adjusting parts 400 to compress the tension spring 304, thereby increasing the amount of contraction of the tension spring 304 and thus increasing the elastic force of the tension spring 304. This allows the tension of the connecting strap 201 to be adjusted according to the different weights of the VR teaching glasses main body 100.

[0031] The specific structure of the adjustment unit 400 can be as follows: Figure 7 In the embodiment shown, the adjustment unit 400 includes a connecting plate 401. The two ends of the connecting plate 401 pass through sliding grooves 306 on the two side mounting housings 301 and are detachably connected to the outer wall of the adjustment pressure plate 305. An adjustment plate 402 is fixedly connected to the outer wall of the adjustment unit 400 between the two side mounting housings 301. Mounting horizontal plates 406 are detachably connected to both the upper and lower sides between the two side mounting housings 301. Adjustment screws 403 are rotatably connected to the mounting horizontal plates 406 on both sides. The adjustment plate 402 is threadedly connected to the outer wall of the adjustment screw 403. Adjustment knobs 404 are detachably connected to both ends of the adjustment screw 403. In this embodiment, by rotating the adjustment knob 404 on either side to drive the adjustment screw 403 to rotate, the adjustment plate 402 can move upward or downward on the outer wall of the adjustment screw 403, thereby driving the adjustment pressure plate 305 to move up and down along the outer wall of the sliding rod 303, thereby controlling the contraction of the tension spring 304, and thereby adjusting the tension of the connecting belt 201.

[0032] To prevent external impurities from contacting the adjusting screw 403 and causing it to jam and become unable to rotate, the specific structure can be as follows: Figure 7 In the embodiment shown, a protective vertical plate 405 is detachably connected between the horizontal plates 406 on both sides. The protective vertical plate 405 passes through the adjusting plate 402. In this embodiment, by setting the protective vertical plate 405, the exposed area of ​​the adjusting screw 403 can be reduced, the contact of external impurities with the adjusting screw 403 can be reduced, and the stability of the adjusting part 400 can be guaranteed.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
