Description

Technical Field

[0001] The present invention relates to the technical field of AR helmets, and particularly to a multi-modal interactive AR remote teaching helmet. Background Art

[0002] In recent years, the application of AR technology in the field of distance education has become increasingly widespread. AR remote teaching helmets enhance the teaching immersion and learning efficiency through the interactive method of virtual-reality integration. In order to better interact with users during the teaching process, some AR helmets introduce multi-modal interaction technology and can adopt an operation mode combining voice and gestures for interaction, which can effectively improve the interaction effect during the teaching process.

[0003] However, there are still certain deficiencies in the actual use of such AR helmets. First, the added electronic modules make the entire AR helmet have higher requirements for heat dissipation during use. After long-term use, the heat generated by the electronic modules may even affect the temperature inside the AR helmet, causing discomfort when the user wears it. Second, when wearing an AR helmet for a long time, the user needs to continuously gaze at the near-eye display screen, which easily leads to eye muscle fatigue, dryness, and even visual fatigue syndrome. Existing AR devices mainly relieve visual fatigue through software adjustment, such as blue light filtering or brightness adaptation, but lack physical intervention means and cannot effectively relax the eye muscles, affecting the long-term use comfort of users. Therefore, this application provides a multi-modal interactive AR remote teaching helmet to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-modal interactive AR remote teaching helmet to solve the problems of existing AR helmets.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A multi-modal interactive AR remote teaching helmet, including an AR helmet. An air pump and a control module are symmetrically arranged outside the AR helmet, and power amplifier modules are symmetrically installed on both sides of the AR helmet. A gas storage chamber is fixedly connected to the bottom end of the control module, and a protective strip is fixedly connected to the outside of the control module. A display screen is fixedly connected to the bottom end of the gas storage chamber, and annular tubes are symmetrically installed inside the display screen. A cavity is formed inside the AR helmet, and evenly distributed partition strips are fixedly connected in the cavity; a cooling component for quickly cooling the control module after it generates heat, and the cooling component is connected to the partition strips; a massage component for pneumatically massaging the user's eye area, and the massage component is connected to the annular tubes; a cleaning component for spraying and cleaning the display area of the display screen, and the cleaning component is connected to the gas storage chamber.

[0007] Optionally, a lining pad corresponding to the distribution position of the partition strip is fixedly connected to the inner side wall of the AR helmet, and a strap is fixedly connected to the bottom end of the AR helmet. The protective strip is located inside the AR helmet, and symmetrically distributed first weakening grooves are formed in the protective strip.

[0008] Optionally, the cooling component includes plastic tubes fixedly connected to both ends of the partition strip. The partition strip divides the space in the cavity into evenly distributed air ducts. The inside of the plastic tube is hollow, and the air duct formed by the plastic tube and the partition strip is communicated through a communication port.

[0009] Optionally, the air pump is communicated with the plastic tube at one end of the partition strip through a pipeline, and the plastic tube at the other end of the partition strip is communicated with the outer shell of the control module through a pipeline.

[0010] Optionally, the massage component includes massage heads fixedly connected to the annular tube. The massage heads are arranged in a U shape on the side of the annular tube away from the display screen. A soft padding is wrapped on the side of the annular tube where the massage heads are arranged. The air storage chamber is communicated with the annular tube and the outer shell of the control module through pipelines.

[0011] Optionally, the massage head is fixedly connected to the annular tube through a connecting seat. A sealing pad is wound around the outside of the connecting seat, and a corrugated first deformation area is arranged at the connection between the connecting seat and the massage head. The annular tube, the massage head and the connecting seat are all hollow structures, and the connecting seat is communicated with the annular tube through a first ventilation hole.

[0012] Optionally, an elastic bracket is fixedly connected between the inner side wall of the connecting seat and the inner side wall of the massage head. One end of the elastic bracket away from the connecting seat is fixedly connected with a support end adapted to the shape of the inner side wall of the massage head. A second deformation area in an S shape is fixedly connected between the support end and the elastic bracket, and the support end is fixedly connected to the inner side wall of the massage head.

[0013] Optionally, the sealing pad is a hollow structure, and a second weakening groove is arranged at the connection between the sealing pad and the connecting seat. The sealing pad is communicated with the connecting seat through evenly distributed second ventilation holes.

[0014] Optionally, the cleaning component includes arc-shaped tubes and electronic valves symmetrically installed outside the air storage chamber. The installation position of the arc-shaped tubes corresponds to the position of the annular tube, and the arc-shaped tubes are communicated with the air storage chamber through the electronic valves. Uniformly distributed spray ports are arranged on the outside of the arc-shaped tubes.

[0015] Optionally, air-permeable openings are evenly distributed on the side of the annular tube close to the display screen. The distribution area of the air-permeable openings corresponds to the distribution area of the ejection openings, and guide vanes are fixedly connected in the air-permeable openings and are evenly distributed.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting the cooling component, on the one hand, the control module can be quickly cooled when the user is resting, providing a good heat dissipation environment for the control module, ensuring the working efficiency and service life of the control module during long-term operation. On the other hand, the temperature at the position of the inner gasket can be effectively reduced, avoiding the situation of heat accumulation on the user's head after wearing the device, and ensuring the comfort of the user after wearing the device.

[0018] By setting the massage component, using the air inflated by the air pump, the massage heads in the massage component expand and perform pneumatic massage on the eye periphery of the patient. Thus, after the user studies for a long time, it can effectively help the user relax the eye muscles, further improve the comfort of the user during long-term use, and then ensure the long-term learning efficiency of the user.

[0019] By setting the cleaning component, the airflow after massage and cooling is further utilized. The airflow is discharged during the working gap of the massage component to clean the display area of the display screen, avoiding the appearance of water mist on the display screen. At the same time, when the airflow is discharged, the massage heads of the massage component can also be reset, repeating the operations of inflation and exhaust, so that the massage component repeatedly squeezes, ensuring the massage effect while synchronously completing the massage relaxation and the cleaning of the display screen, making the structures of each component cooperate with each other, and the technical solution is more complete.

[0020] By setting the elastic support, the second deformation area and the support end in the massage head, when the massage head expands for massage, the support end can ensure the hardness of the end of the massage head. When the cleaning component works, the second deformation area and the first deformation area can quickly drive the whole massage head to reset, reducing the extrusion effect on the user's eye periphery, thereby ensuring the massage effect. At the same time, the quick reset of the massage head can also ensure the rapid ejection of the air in the cleaning component, ensuring the cleaning effect, and further improving the respective functions.

[0040] As Figures 1 to 10As shown, the embodiment of the present invention provides a multi-modal interactive AR remote teaching helmet, including an AR helmet 1. An air pump 9 and a control module 10 are symmetrically arranged outside the AR helmet 1. Power amplifier modules 3 are symmetrically installed on both sides of the AR helmet 1. The AR helmet 1 is used for wearing the entire device, ensuring that the device can be stably worn on the user's head and enabling each accessory on the device to be in its working position, capable of providing a good remote teaching effect for the user. The power amplifier modules 3 are symmetrically arranged on both sides of the AR helmet 1 and correspond to the user's ear positions after the AR helmet 1 is worn, capable of maintaining the audio-visual synchronization of teaching materials during remote teaching and providing a good teaching effect. The bottom end of the control module 10 is fixedly connected to an air storage chamber 4, and a protective strip 15 is fixedly connected to the outside of the control module 10. The bottom end of the air storage chamber 4 is fixedly connected to a display screen 5. The control module 10 is used to control the operation of the entire device and display teaching materials through the display screen 5. The control module 10 is equipped with multi-modal interactive elements, capable of providing feedback in cooperation with the user's language or gesture control, thus achieving a better interactive effect during teaching. The principles and usage processes of the above-mentioned power amplifier modules 3, air storage chamber 4, and display screen 5 are the same as those of the prior art and will not be elaborated here. Ring-shaped tubes 6 are symmetrically installed inside the display screen 5. A cavity 12 is formed inside the AR helmet 1, and evenly distributed partition strips 11 are fixedly connected in the cavity 12. Inner padding 2 corresponding to the distribution positions of the partition strips 11 is fixedly connected to the inner side wall of the AR helmet 1, and a strap is fixedly connected to the bottom end of the AR helmet 1. The protective strip 15 is located inside the AR helmet 1, and symmetrically distributed first weakening grooves 18 are formed on the protective strip 15. The protective strip 15 is provided to separate the control module 10 from the user's head, capable of protecting both the control module 10 and the user's head. The first weakening grooves 18 make the thickness value of the protective strip 15 thinner and the strength weaker at the first weakening grooves 18, making it easier to deform under external force, ensuring the heat dissipation environment of the control module 10 while providing good separation and protection effects, and also avoiding the user's head from being knocked when wearing. The cavity 12 inside the AR helmet 1 makes the overall structure of the AR helmet 1 lighter, and the burden on the user after wearing the device is smaller. The partition strips 11 can, on the one hand, compensate for the structural strength of the lightweight AR helmet 1, and on the other hand, form an air duct in the AR helmet 1. After the air pump 9 pumps external air into the device, the flow path of the air can be controlled, allowing the cooler external air to pass through the air duct formed by the partition strips 11 to cool the area where the inner padding 2 is located, improving the comfort of the user during the use process after wearing the device;

[0041] A cooling component is used to quickly cool down the Module 10 after it generates heat during operation. The cooling component is connected to the partition strip 11. The arrangement of the cooling component makes reasonable use of the cold air extracted from outside the device by the air pump 9, improving the comfort of the user when wearing the device. At the same time, the cold air is used to quickly cool down the Module 10 after it generates heat, and its working time corresponds to the user's rest time. While the user takes a break in the middle, eye perimeter massage for the user and rapid cooling of the Module 10 are carried out synchronously; A massage component is used to pneumatically massage the eye perimeter of the patient. The massage component is connected to the annular tube 6. The arrangement of the massage component can utilize the air inflated by the air pump 9 to make the structure of the massage component expand and move, and massage the eye perimeter of the patient during the teaching break to relieve the user's fatigue; A cleaning component is used to spray and clean the display area of the display screen 5. The cleaning component is connected to the air storage chamber 4. The cleaning component can further utilize the airflow after cooling and heat dissipation and pneumatic massage, making the airflow spray and act on the display area of the display screen 5 to clean the water mist formed on the display screen 5 due to the user's breathing or sweat volatilization during wearing, ensuring the display effect of the display screen 5.

[0042] In this embodiment, as Figures 3 to 6 shown, the cooling component includes plastic tubes 13 fixedly connected to both ends of the partition strip 11. The partition strip 11 divides the space in the cavity 12 into evenly distributed air ducts. The inside of the plastic tube 13 is hollow, and the air duct formed by the plastic tube 13 and the partition strip 11 is connected through a communication port 14. The air pump 9 is connected to the plastic tube 13 at one end of the partition strip 11 through a pipeline, and the plastic tube 13 at the other end of the partition strip 11 is connected to the housing of the Module 10 through a pipeline. The setting of the inner gasket 2 makes the inside of the AR helmet 1 made of soft-pack material, which fits better with the user's head, making the user more comfortable when wearing the AR helmet 1. However, this soft-pack material will also cause the user's head to accumulate heat after long-term wearing and learning, resulting in a stuffy feeling. The setting of the partition strip 11 can divide the top space of the cavity 12 into evenly distributed air ducts. Coupled with the hollow structure of the plastic tube 13 and the pipeline connection between the spaces, the cold air extracted by the air pump 9 can pass through within the range restricted by the air ducts, and then the temperature of the area corresponding to the air ducts in the AR helmet 1 will be lower, thereby reducing the heat accumulation at the position where the inner gasket 2 is located, making the user more comfortable when wearing the device for learning. At the same time, it also forms a communication channel between the air pump 9 and the Module 10. The cold air extracted by the air pump 9 can not only improve the comfort of the user when wearing, but also, when the Module 10 stops teaching, assist in the rapid cooling of the Module 10, send the cold air into the housing of the Module 10, absorb the heat dissipated by the Module 10, and take out the heat in the housing of the Module 10, providing a good working environment for the Module 10.

[0043] In this embodiment, as Figures 5 to 10 shown, the massage component includes massage heads 7 fixedly connected to the annular tube 6. The massage heads 7 are arranged in a U shape on the side of the annular tube 6 away from the display screen 5. A soft cushion 19 is wrapped around the side of the annular tube 6 where the massage heads 7 are provided. The setting of the soft cushion 19 can enhance the comfort when the annular tube 6 contacts the user's eye circumference. The annular tube 6 is overall in a square shape, corresponding to the shape of the user's eye circumference, and surrounds the display screen 5. During the process of remote teaching, in cooperation with the display screen 5, a teaching display area is formed. The U-shaped arrangement state of the massage heads 7 covers the top side and two side sides of the square structure of the annular tube 6, corresponding to the user's eye acupuncture points. During the user's rest period, through the inflation of the air pump 9, the massage heads 7 are inflated to squeeze and press the user's eye acupuncture points, thereby effectively relieving the user's fatigue. The air storage chamber 4 is communicated with the annular tube 6 and the outer shell of the control module 10 through pipelines. The communication relationship among the air storage chamber 4, the annular tube 6, and the outer shell of the control module 10 also ensures the air flow path, allowing the air that has taken away the heat in the control module 10 to be filled into the massage heads 7, causing the massage heads 7 to expand and perform massage. At the same time, the hot air taken away can also increase the external temperature of the massage heads 7, playing a certain hot compress role, making the massage effect of the massage heads 7 further improved. The massage heads 7 are fixedly connected to the annular tube 6 through connecting seats 22. A sealing gasket 24 is wound around the outside of the connecting seats 22, and a corrugated first deformation area 25 is provided at the connection between the connecting seats 22 and the massage heads 7. The annular tube 6, the massage heads 7, and the connecting seats 22 are all hollow structures. The connecting seats 22 are communicated with the annular tube 6 through first ventilation holes 23. In order to ensure its inflation effect, the massage heads 7 are made of elastic materials. After long-term use, it is inevitable that they will age and be damaged. The setting of the connecting seats 22 makes the connection between the massage heads 7 and the annular tube 6 a detachable connection relationship, allowing the massage heads 7 to be separately disassembled and replaced after aging and damage, maintaining the user's usage effect while reducing the later maintenance cost. Openings adapted to the size of the connecting seats 22 are provided on the massage heads 7. After the connecting seats 22 are inserted from the openings, the sealing gaskets 24 will fit with the inner side wall of the annular tube 6, keeping the connection between the annular tube 6 and the massage heads 7 sealed, avoiding air leakage, and ensuring the pneumatic massage effect of the massage heads 7.

[0044] An elastic support 28 is fixedly connected between the inner side wall of the connecting seat 22 and the inner side wall of the massage head 7. One end of the elastic support 28 away from the connecting seat 22 is fixedly connected with a support end 30 adapted to the shape of the inner side wall of the massage head 7. A second deformation zone 29 in an S shape is fixedly connected between the support end 30 and the elastic support 28, and the support end 30 is fixedly connected to the inner side wall of the massage head 7. The elastic support 28, the second deformation zone 29 and the support end 30 are provided to maintain the overall structural shape of the massage head 7 on the one hand. Through the S-shaped second deformation zone 29 and the corrugated first deformation zone 25, both the massage head 7 and the elastic support 28 can deform after the massage head 7 is inflated, and even if deformation occurs, the shape of the massage head 7 can be maintained by the elastic support 28. On the other hand, the position of the support end 30 corresponds to the position of the massage head 7, and can maintain the hardness when the massage head 7 contacts the skin around the user's eyes during the massage process, ensuring the massage effect. The sealing gasket 24 is a hollow structure, and a second weakening groove 26 is provided at the connection between the sealing gasket 24 and the connecting seat 22. The second weakening groove 26 makes the overall thickness value of the sealing gasket 24 thinner at the second weakening groove 26, which can guide the deformation of the sealing gasket 24 after being squeezed, so that the sealing gasket 24 can better deform and fit on the outside of the connecting seat 22 during the process of inserting the connecting seat 22 into the annular tube 6, facilitating the insertion and connection operation of the connecting seat 22. The sealing gasket 24 is communicated with the connecting seat 22 through uniformly distributed second air holes 27. When the massage head 7 is inflated, gas will also enter the sealing gasket 24 through the second air holes 27, causing the sealing gasket 24 to expand to a certain extent, and then fitting more tightly with the inner side wall of the annular tube 6, further ensuring the sealing effect at the connection between the massage head 7 and the annular tube 6.

[0045] In this embodiment, as Figures 5 to 7As shown, the cleaning component includes arc-shaped tubes 8 and electronic valves 16 symmetrically installed outside the air storage chamber 4. The installation position of the arc-shaped tubes 8 corresponds to that of the annular tube 6, and the arc-shaped tubes 8 are connected to the air storage chamber 4 through the electronic valves 16. Uniformly distributed spray ports 17 are provided on the outer side of the arc-shaped tubes 8. Uniformly distributed air-permeable openings 20 are provided on the side of the annular tube 6 close to the display screen 5. The distribution area of the air-permeable openings 20 corresponds to that of the spray ports 17. Uniformly distributed flow guide vanes 21 are fixedly connected in the air-permeable openings 20. During the process of users wearing and studying, water mist will be formed on the display screen 5 due to breathing or the volatilization of sweat. The air-permeable openings 20 provided on the annular tube 6 can enable the air in the inner space of the annular tube 6 to exchange with the outside air through the air-permeable openings 20 during the normal learning process, thereby reducing the generation of water mist. The setting of the flow guide vanes 21 can guide the air flow when the cleaning component works to ensure the discharge path of the air flow used to clean the water mist. However, as the learning time increases, it is inevitable that the accumulated water mist will affect the display effect of the display screen 5. At this time, by taking advantage of the user's rest time, the electronic valve 16 on the air storage chamber 4 can work and open, opening the channel between the air storage chamber 4 and the arc-shaped tubes 8, allowing the accumulated air in the air storage chamber 4 to be ejected through the spray ports 17 on the arc-shaped tubes 8, so that the ejected air flow acts on the display screen 5 to quickly eliminate the water mist on the display screen 5 and keep the display area of the display screen 5 clean. At the same time as the air in the air storage chamber 4 is ejected, the massage heads 7 will also quickly reset under the elastic force of the elastic support 28, reducing the pressure on the user's eye area. By repeating this, while ensuring the eye area massage effect, the cleaning of the water mist on the display screen 5 is completed. At the same time, the air used to clean the water mist on the display screen 5 also takes out the heat generated when the control module 10 works. The heated air not only plays a hot compress role on the user's eye area, but also can accelerate the removal effect of the water mist.

For the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0047] The above are only the preferred embodiments of the present invention.
