Description

TECHNICAL FIELD

[0001] The utility model belongs to virtual reality technical field, concretely relates to a kind of intelligent experiment virtual simulation teaching equipment. BACKGROUND

[0002] As intelligent experiment virtual simulation teaching equipment, VR glasses can provide highly realistic virtual experiment scenes for users through high-resolution display screens and precise optical systems, making students feel as if they are in the scene, and fully immerse themselves in the experimental environment, enhancing the sense of immersion and concentration of learning.

[0003] Some education scenarios use VR glasses in the prior art. Since it is necessary to ensure that each student can use VR glasses for a long time, the equipment is usually prone to overheating. When the VR glasses are overheated and the temperature is higher than the skin temperature of the student's face, the human body will dissipate heat through sweating to regulate body temperature. After the sweat evaporates, water vapor is formed, which will accumulate in the relatively closed contact area between the VR glasses and the face, forming water vapor. If these water vapor cannot be discharged in time, not only can it cause the VR glasses lens to be blurred, but also it can interact with the skin oil remaining on the surface of the VR glasses, causing the growth and reproduction of bacteria, fungi and other microorganisms in the VR glasses cavity.

[0026] Referring to Figures 1-5 For the embodiment of the utility model, the embodiment provides an intelligent experiment virtual simulation teaching device, which comprises,

[0027] The VR glasses body 100 includes a frame 110, a display screen 120 mounted on the outer surface of the frame 110, a lens 130 fixedly mounted on the inner wall of the frame 110 and matched with the display screen 120, and a breathable port 160 extending through the outer side of the frame 110 to the inner side and used for preventing water vapor from gathering in the frame 110.

[0028] It should be noted that the frame 110 is a support structure of the VR glasses body 100, used for mounting the display screen 120, the lens 130, the fixing band 140 and the anti-slip rubber ring 150, providing mounting positions and physical support for them. The display screen 120 is used for displaying image information of a virtual experiment scene, providing a realistic visual experience for students through a high-resolution picture, making students feel as if they are in a virtual experiment environment. The lens 130 can refract or perform other optical processing on the light emitted by the display screen 120, adjust the light propagation path, and make the image clearly imaged on the human eye retina, ensuring that students can see clear and distortion-free virtual pictures, improving visual effect and immersion. The fixing band 140 is used for fixing the frame 110 on the head of a student, ensuring the position stability of the frame 110 during use. The anti-slip rubber ring 150 is used for increasing the friction between the VR glasses body 100 and the face, preventing the VR glasses body 100 from sliding during wearing, providing a certain buffer, reducing the pressure of the VR glasses body 100 on the face, and improving the wearing comfort. During the use of the device, water vapor is easily generated due to human body heat dissipation and sweating in the VR glasses. The breathable port 160 can make the air circulate and discharge the water vapor in time, preventing the water vapor from gathering in the frame 110, avoiding the lens from being blurred due to water vapor, and preventing bacteria and fungi from breeding due to the mixture of water vapor and skin oil.

[0029] The moisture-proof mechanism 200 includes a protection assembly 210 for preventing dust from entering the frame 110 through the breathable port 160, and a transmission assembly 220 for driving the protection assembly 210 to close the breathable port 160. The transmission assembly 220 is arranged outside the protection assembly 210.

[0030] Specifically, the protection assembly 210 includes a fixed plate 211 fixedly connected to the outer surface of the frame 110, an arc-shaped guide rail 212 fixedly mounted on the outer side of the fixed plate 211, and a connecting plate 213 fixedly connected to the other side of the arc-shaped guide rail 212.

[0034] It should be noted that the transmission assembly 220 further comprises a plurality of force applying grooves 226 formed on the outer surface of the arc-shaped sliding plate 225, a force receiving column 227 arranged on the inner side of the force applying groove 226, a swing block 228 fixedly connected to the outer end surface of the force applying groove 226 and cooperating with the movable plate 215, and a spring 229 sleeved on the outer side of the sliding rod 224.

[0036] Further, the force applying groove 226, the stress column 227, the swing block 228, the rotating column 214 and the movable plate 215 are provided with the same number, and the outer end surface of the spring 229 is fixedly connected with the outer surface of the sliding rod 224.

[0037] Specifically, the VR glasses body 100 further comprises a fixed band 140 fixedly connected to the outer side of the frame 110 and an anti-skid rubber ring 150 fixedly installed on the inner side of the frame 110.

[0038] In use, the student first wears the frame 110 on the head through the fixed band 140, increases the friction with the face and reduces the pressure through the anti-skid rubber ring 150, improves the wearing comfort, presents a high-resolution virtual experimental scene image through the display screen 120 after starting the equipment, processes the light through the lens 130, and enables the student to see a clear and realistic picture and immerse in the virtual experimental environment.

[0039] With the increase of use time, the electrical elements in the VR glasses body 100 continuously heat up, causing the student to sweat and generating water vapor in the VR glasses body 100, at this time, the heat generated by the electrical elements is transmitted to the thermal expansion block 223 in the heat conducting sleeve 222, so that the thermal expansion block 223 is heated and expanded, and the sliding rod 224 is pushed to move along the inner surface of the heat conducting sleeve 222, the hinged arc-shaped sliding plate 225 is driven to move along the inner wall of the arc-shaped guide rail 212 through the sliding rod 224, the arc-shaped sliding plate 225 pushes the stress column 227 to move through the force applying groove 226, the stress column 227 drives the movable plate 215 to rotate around the rotating column 214 through the swing block 228, so that the air vent 160 is opened, the air in the frame 110 flows, and the water vapor is discharged in time, avoiding the lens 130 being blurred and the bacteria breeding in the frame 110;

[0040] After the student uses the device and takes off the device, the temperature of the VR glasses body 100 gradually decreases, the thermal expansion block 223 cools and shrinks, the sliding rod 224 moves reversely under the reaction force of the spring 229, the arc-shaped sliding plate 225 moves reversely, and the arc-shaped sliding plate 225 drives the movable plate 215 to rotate reversely, thereby closing the air vent 160 and preventing external dust from entering the inside of the frame 110 through the air vent, so as to protect the inside of the device and keep it clean for the next use.

[0041] In summary, through the cooperation of the components in the moisture-proof mechanism 200, not only can the movable plate 215 be automatically opened to timely discharge water vapor and prevent the lens 130 from being fogged when the temperature of the VR glasses body 100 is too high after long-time use, but also the movable plate 215 can be automatically controlled to rotate reversely to close the air vent 160 after the use of the VR glasses body 100 is finished, so as to prevent external dust from entering the inside of the frame 110 through the air vent 160 and adhering to the surface of the lens 130, thereby achieving the effect of ensuring the clear vision of the student in the virtual experiment while maintaining the stable performance of the device.
