Description

Technical Field

[0001] The present invention relates to the technical field of ski helmets, in particular to a multifunctional intelligent ski helmet. Background Art

[0002] A ski helmet is a commonly used piece of protective gear for skiing. There are two types of ski helmets: those with built-in visors and those without. Ski helmets without built-in visors require separate goggles before skiing, and wearing them requires careful adjustment between the goggles, the helmet, and the user's eyes, which is very troublesome. Furthermore, the goggles are easily lost when the user takes a break. While built-in visors are easier to wear and less likely to be lost than helmets without them, when skiing, the exhaled air can easily form mist around the goggles, obstructing the user's vision. Skiing speeds generally reach 50 km / h, with a maximum speed of 130 km / h. If the mist obstructs the skier's vision, accidents can easily occur.

[0003] The existing ski helmet anti-fog treatment method for goggles is to apply an anti-fog coating on the lenses, but this method can only reduce the adhesion of fog. When too much water mist is exhaled, it will still adhere to the goggles and affect the user's vision.

[0004] To this end, a multifunctional intelligent ski helmet is proposed. For ski helmets with built-in goggles, an anti-shielding device is provided on it, so that it can automatically clean the water mist on the goggles of the ski helmet to prevent the water mist from adhering to the goggles and affecting the skier's vision. At the same time, it can also prevent snowflakes from adhering to the goggles and affecting the skier's vision. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional intelligent ski helmet. By setting an anti-obstruction device, when the user uses the ski helmet, the water mist generated by the goggles on the helmet and the snowflakes adhering to the front of the goggles can be automatically cleared, ensuring that the user's vision is not blocked during use, avoiding safety accidents caused by the user's unclear view of the road conditions due to fog and snowflakes adhering to the helmet goggles.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A multifunctional intelligent ski helmet, comprising:

[0008] Helmet body;

[0009] The fixing belt is fixed on the helmet body and is used to fix the helmet body to the human head; the fixing belt can be an elastic rope belt to ensure that it can adapt to different user head shapes.

[0010] Goggles, which are rotatably mounted on the helmet body and are made of tempered glass;

[0011] The goggles are equipped with an anti-obstruction device to prevent the user's vision from being obstructed by fog while skiing. The anti-obstruction device can be a wiper blade similar to a windshield wiper, or other device or equipment capable of preventing the goggles from being obstructed by fog or snow. The anti-obstruction device includes a defogging module for clearing fog from the goggles and a control module for controlling the power of the defogging module. The defogging module of the anti-obstruction device clears fog generated on the goggles, preventing the fog exhaled by the user from adhering to the goggles and obstructing the vision, thereby improving safety during skiing. The control module can adjust the power of the defogging module to ensure stable operation and improve the stability of the device.

[0012] Preferably, the demisting module includes a power supply fixedly mounted on the helmet body, employing a rechargeable battery as a power source. The power supply is fixedly mounted within the interlayer of the helmet body, or the power supply can be independently fixed to the outer shell of the helmet. Fixing the power supply within the interlayer of the helmet body minimizes the power supply from adding wind resistance when the user is skiing, while fixing it within the interlayer of the helmet body eliminates additional wind resistance and better protects the power supply from damage. However, fixing the power supply within the interlayer makes installation and replacement more complicated and difficult, and increases processing and cost. The edge of the goggles is surrounded by an electric heating element for heating the lenses of the goggles. The electric heating element can be an electric heating core, an electric heating wire, an electric heating film, a mica heating sheet, or other elements that have a heating effect when powered on. The electric heating element is electrically connected to the power supply through an electric wire. The electric wire can be wired from the outside of the helmet body to connect the power supply to the electric heating element. Alternatively, a wire hole or a wire groove can be opened on the frame of the goggles to guide the wires of the electric heating element to the rotating shaft where the goggles are connected to the helmet body, and electrically connected to the power supply inside the helmet body at the rotating shaft. When a user wears a ski helmet and turns on a power switch, the electric heating element connected to the power supply will generate heat after being energized. The electric heating element will heat the lenses of the goggles in contact with the helmet starting from the edges. The mist on the lenses is formed because the water vapor exhaled by the person contacts the cold lenses and condenses on the lenses. When the lenses of the goggles are heated by the electric heating element to a temperature greater than or equal to the temperature of the exhaled air, the exhaled air will not condense on the goggles, and the water mist will not block the user's vision, thereby improving the safety of the user when skiing. Meanwhile, heating the lens starting at the edge of the lens slows down the transfer of heat to the center. However, compared to heating through holes drilled through the lens, this method eliminates the need for heating elements to obstruct vision. While uniformly drilling holes throughout the lens and then heating it with hot air or hot water can increase heat transfer and evenly distribute heat across the lens, this method complicates lens manufacturing, makes the lens thicker and heavier, and increases costs. It also reduces the strength of the lens, making it more susceptible to breakage and eye injury in the event of a fall or collision. Furthermore, heating the lens by heating water and air, and then using hot water and air to heat the lens, requires more energy. Because water freezes at low temperatures, heating the water requires more heat. The hot air requires an air pump to distribute it throughout the lens holes for uniform heating, increasing production and energy costs. Without an air pump, the thermal conductivity of air in a closed state is only 0.023 W / m·k, making the transfer less effective than directly heating the lens. In order to quickly transfer the heat generated by the heating element to all parts of the lens, metal ions can be added during lens processing to increase the thermal conductivity of the lens.

[0013] Preferably, the control module includes one or more temperature sensors fixedly mounted on the inner side of the goggles near the human eye, the temperature sensors being patch-type temperature sensors located at the edge of the side, closely attached to the lens of the goggles and detecting the temperature of the lens, and electrically connected to the electric heating element. The temperature sensor monitors the temperature of the lens when the electric heating element heats the lens, and controls the power of the electric heating element to control the temperature of the lens within a range of plus or minus 10 percent of the temperature of the air exhaled by the human body. That is, the normal human body temperature is 36-37°C, and the monitoring range of the temperature sensor is 36-37°C ± 10%. The ±10% is selected because the air exhaled by the human body will be affected by the environment and its temperature will decrease. Therefore, an appropriate temperature can be selected according to the actual situation. Selecting a temperature 10% higher than 36-37°C will not produce water mist, but will increase energy consumption. When the temperature is detected to be lower than the set range, the temperature sensor feeds back to the electric heating element, which increases the power of the electric heating element and quickly heats the lens to a temperature higher than the range. When the temperature reaches the set range, the electric heating element enters the heat preservation state, maintaining the same temperature as the set temperature to heat the lens and keep the lens warm. When the temperature of the lens is detected to be higher than the set range, the temperature sensor feeds back to the electric heating element, and the electric heating element enters the stop heating state to save energy and avoid drying out the human eyes due to excessive temperature, thereby improving the comfort of the equipment. If multiple sensors are used to detect the temperature of the goggles, the sensors are evenly arranged along the edge of the goggles, and the average value of the detection of multiple temperature sensors is used as the value fed back to the electric heating element.

[0014] Preferably, a U-shaped groove is formed in an annular shape on the edge of the goggles, and the electric heating element is fixedly installed inside the U-shaped groove. Placing the electric heating element inside the U-shaped groove so that the U-shaped groove wraps around the electric heating element can increase the contact area between the electric heating element and the lens, allowing the heat of the electric heating element to be transferred to the lens more quickly, thereby improving the heating efficiency of the goggles and accelerating the removal of water mist.

[0015] Preferably, the control module further comprises a plurality of infrared emitting tubes disposed on the outer side of the goggles, away from the eye, for detecting snow on the lenses. The plurality of infrared emitting tubes for detecting snow on the lenses are disposed vertically downward above the outer side of the goggles, away from the eye. The infrared emitting tubes are arranged horizontally along the top of the goggles. Directly below the infrared emitting tubes are correspondingly disposed a plurality of infrared receiving tubes, each electrically connected to the electric heating element. The infrared emitting tubes emit infrared light from top to bottom, and the corresponding infrared receiving tubes below receive the infrared light emitted from above. When a snowball adheres to the goggles, the snowball blocks the infrared light from the infrared emitting tubes, preventing the corresponding infrared receiving tubes from receiving the infrared light. A signal is then fed back to the electric heating element, causing the electric heating element to operate at a power level lower than the set temperature range. This feedback precedence takes precedence over the keep warm and stop heating modes. Heating will only proceed according to the temperature monitored by the temperature sensor when all infrared receiving tubes are receiving the infrared light emitted by the infrared emitting tubes. An infrared emitting tube and an infrared receiving tube detect whether the goggles are clinging to snowballs, and the power of the electric heating element is adjusted to melt the snowballs promptly, preventing them from obstructing the user's vision and improving skiing safety. Because small snowflakes are quickly melted by the goggles upon contact, there's no need to adjust the power of the electric heating element. Only when the infrared receiving tube's signal is blocked, indicating a large snowball, is the power of the electric heating element increased to accelerate its melting.

[0016] Preferably, one or more of the temperature sensors are wrapped with a heat-insulating material, and the U-shaped groove provided at the edge of the goggles is also sealed with a heat-insulating material. The heat-insulating material may be, for example, asbestos felt, polyurethane foam, aerogel felt, or other materials capable of achieving a heat-insulating effect. The heat-insulating material can reduce the interference of the temperature sensor with the external environment and improve the accuracy of the temperature sensor in monitoring the temperature of the goggles. Sealing the U-shaped groove with a heat-insulating material and wrapping the electric heating element inside the U-shaped groove can reduce the heat transfer from the electric heating element to the outside, so that the heat generated by the electric heating element is absorbed by the lens of the goggles as much as possible, thereby improving the utilization rate of the heat generated by the electric heating element.

[0017] Preferably, the U-shaped groove is filled with thermal grease, which further fills the gap between the electric heating element and the U-shaped groove, thereby increasing the rate at which heat from the electric heating element is transferred to the goggles.

[0018] Preferably, energy replenishment devices are provided on both the left and right sides of the helmet, and each energy replenishment device includes a fixing frame fixed to the helmet body, a micro wind generator is installed inside the fixing frame, and the micro wind generator is electrically connected to a power source. The blades of the micro wind generator are arranged vertically, and the blades of the micro wind generator rotate with the help of the airflow when the user is skiing to generate electricity. The generated electricity is then supplemented to the power source after rectification. Because skiing is a high-speed sport from top to bottom, high-speed airflow is generated during the sport. Rational use of high-speed airflow to supplement the power source reduces the need for charging the power source, extends the service life of the anti-shielding device, and conforms to the concept of green environmental protection.

[0019] Preferably, the helmet body is provided with an exhaust pipe, located between the goggles and the user's eyes, connecting the space between the goggles and eyes with the external space at the top of the helmet body. During skiing, the airflow at the top of the helmet body is high, and the user's exhaled air is carried upward by the Venturi effect, reducing the possibility of the user's exhaled air adhering to the goggles and forming mist. This further ensures that the user's vision is not obstructed while skiing, improves the stability of the device, and ensures the user's safety.

[0020] Preferably, the exhaust pipe is inclined upward toward the rear of the helmet body. The upwardly inclined exhaust pipe extends in the direction of the helmet body toward the rear of the helmet body to accelerate the discharge speed of exhaled air. A groove is defined in the middle of the exhaust pipe. The groove is spherical. A sphere is disposed within the groove to control the exhaust speed of the exhaust pipe. The sphere is a hollow plastic sphere. When the speed is slow, the flow of gas in the exhaust pipe drives the gas between the user's eyes and goggles to flow out of the helmet body through the exhaust pipe. When the speed of gas flow at the top of the helmet body increases, the flow of gas in the exhaust pipe also increases, and the airflow drives the sphere upward within the groove. When the speed of the exhaust pipe is too fast to attract the sphere upward, the sphere blocks the exhaust pipe, preventing the sphere from being discharged. This ensures that the user does not experience breathing difficulties due to the high exhaust speed of the exhaust pipe during high-speed exercise, thereby improving the stability of the device. When the gas flow rate is too low to attract the sphere, the sphere falls under the action of gravity.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Compared with existing ski helmets, the multifunctional intelligent ski helmet described in the present invention is provided with an anti-shielding device. The defogger module of the anti-shielding device is used to heat the goggles of the ski helmet to prevent the gas exhaled by the user from condensing on the goggles and obstructing the user's vision during skiing, thereby avoiding safety accidents caused by fog blocking the user's vision. At the same time, the defogger module is automatically and intelligently controlled in conjunction with the control module to improve the stability of the defogger module and ensure the stability of the equipment during use.

[0023] 2. The multifunctional intelligent ski helmet described in the present invention has a control device provided with multiple infrared emitting tubes and multiple infrared receiving tubes, which detect snow on the front of the goggles to detect whether large snow balls are adhered to the front of the goggles, and feed back the detection signal to the electric heating element of the defogger module to adjust its output power to quickly heat the lenses of the goggles, so that the snow balls melt quickly to avoid obstructing the user's vision, further improving the anti-blocking effect of the equipment and ensuring the personal safety of the user.

[0024] 3. The multifunctional intelligent ski helmet described in the present invention is provided with an exhaust pipe, which utilizes the Venturi effect to discharge the gas exhaled by the user, thereby reducing the possibility of the gas exhaled by the user adhering to the goggles to form water mist, and further avoiding the water mist from affecting the user's vision. At the same time, a groove is provided in the middle of the exhaust pipe, and a ball is provided inside the groove. When the user skis too fast, the gas discharged from the exhaust pipe will adsorb the ball to the exhaust pipe opening at the top of the groove. The ball blocks the exhaust pipe, reducing the gas extraction speed, ensuring that the user will not have difficulty breathing due to the excessively fast gas flow speed at the mouth and nose during high-speed skiing, thereby improving the stability of the equipment and further protecting the life and health of the user.

[0034] Example 1:

[0035] refer to Figures 1 to 7 A multifunctional intelligent ski helmet includes: 1. a helmet body; 2. a fixing strap; 3. goggles; 4. a power supply; 5. an electric heating element; 6. a temperature sensor; 7. a U-shaped groove; 8. an infrared transmitting tube; 9. an infrared receiving tube; 10. a heat-insulating material; 11. thermal grease; 12. a fixing frame; 13. a micro wind turbine; 14. an exhaust pipe; 15. a groove; and 16. a ball.

[0036] The helmet body 1 is made of carbon fiber, the helmet body 1 is a double-layer structure, the fixing belt 2 is an adjustable telescopic belt, the goggles 3 are made of two tempered glasses located in front of the human eyes, the two tempered glasses correspond to the two eyes of the person respectively, and the rest of the position is made of resin. The goggles 3 made of tempered glass are fixedly mounted on the goggles 3 made of resin by gluing, the power supply 4 is a rechargeable lithium battery, and the power supply 4 is fixedly mounted in the interlayer of the helmet body 1. The edges of the goggles 3 made of tempered glass in front of the human eyes are surrounded by a U-shaped groove 7, and an electric heating element 5 is installed inside the U-shaped groove 7. The electric heating element 5 uses a heating wire, each The electric heating elements 5 are respectively wrapped around the goggles 3 made of tempered glass along the U-shaped groove 7 where they are located. Each electric heating element 5 is electrically connected to the power supply 4. A group of patch-type temperature sensors 6 are fixedly installed on each goggles 3 made of tempered glass. There are two temperature sensors 6 in each group, which are installed on the upper and lower sides of the center of one side close to the human eye. Each group of temperature sensors 6 is electrically connected to the electric heating elements 5 on the tempered glass using a PLC. The output value of the temperature detected by each group of temperature sensors 6 adopts the average value. The final heating value of the tempered glass is set to 36°C. When the electric heating element 5 is set to work with heating power, the electric heating element 5 The temperature is 60°C, and when the electric heating element 5 works at the heat preservation power, the temperature of the electric heating element 5 is 36°C. The temperature sensor 6 and the U-shaped groove 7 on each tempered glass are wrapped and sealed with a heat insulating material 10. The heat insulating material 10 is made of aerogel felt. The inside of each sealed U-shaped groove 7 is filled with thermal grease 11. A row of infrared emitting tubes 8 are horizontally installed above the side of each tempered glass away from the human eye. The infrared emitting tubes 8 are closely arranged and installed vertically downward. A row of infrared receiving tubes 9 corresponding to each other are fixedly installed directly below each row of infrared emitting tubes 8. The infrared receiving tubes are all installed vertically upward. The receiving tubes are electrically connected to the electric heating elements 5 through PLC. An energy replenishment device is installed on each side of the helmet body 1. Each energy replenishment device consists of a fixing frame 12 and a micro wind generator 13. The micro wind generator 13 is horizontally installed on the fixing frame 12. Each micro wind generator 13 is electrically connected to the power supply 4 through PLC. An exhaust pipe 14 is provided in the middle of the helmet body 1 between the human eye and the goggles 3. The exhaust pipe 14 is arranged obliquely upward toward the rear of the helmet body 1. A spherical groove 15 is provided in the middle of the exhaust pipe 14, and a hollow ball 16 made of plastic is placed inside the groove 15.

[0037] The specific workflow is as follows:

[0038] Before work: Check whether the power supply 4 of the helmet is fully charged. If not, replace the helmet with one with a fully charged power supply 4 and charge the helmet that is not fully charged.

[0039] The user puts the helmet body 1 on their head and adjusts the tightness of the strap 2 to a level that allows them to breathe easily and prevents slight movement of the head without causing relative rotation between the helmet body 1 and the head. Once adjusted, the user rotates the goggles 3 along the sidewall of the helmet body 1 to their maximum position, shielding the front of the eyes and preventing sunlight from reflecting off the snow and into the eyes during skiing, potentially causing snow blindness. The user then activates the power supply 4, activating the temperature sensor 6 and heating element 5, and begins skiing normally.

[0040] During operation: each infrared emitting tube 8 emits infrared rays downward, and the infrared receiving tube 9 receives the infrared rays emitted by the infrared emitting tube 8. If the infrared receiving tube 9 can receive infrared rays, it means that the outside of the goggles 3 at the tempered glass is not blocked by snow. Then the temperature sensor 6 detects whether the temperature of the goggles 3 at the tempered glass is lower than 36°C. If it is lower than 36°C, the signal is fed back to the electric heating element 5. The electric heating element 5 starts working with heating power. The heating element quickly heats the lenses of the goggles 3 to prevent water vapor in the air exhaled by the user from condensing into water mist on the tempered glass goggles 3 to prevent the water mist from interfering with the user's vision. When the temperature sensor 6 detects that the temperature of the tempered glass lens is equal to or greater than 36°C, the temperature sensor 6 feeds back a signal to the electric heating element 5, and the electric heating element 5 switches to the insulation power to keep the lens temperature at 36°C.

[0041] When snow balls splash in front of the tempered glass lens during skiing, the snow balls block the infrared receiving tube 9 from receiving infrared rays. At this time, the infrared receiving tube 9 feeds back the signal to the electric heating element 5, and the electric heating element 5 starts working at heating power again to quickly melt the snow balls. Until all the infrared receiving tubes 9 can receive infrared rays, the electric heating element 5 resumes working at insulation power to ensure that the user's vision will not be blocked during skiing.

[0042] During skiing, the exhaust pipe 14 on the helmet body 1 draws some of the user's exhaled air out of the helmet through the Venturi effect, reducing the possibility of moisture in the user's exhaled air adhering to the goggles 3 and forming mist, further ensuring that the user's vision is not obstructed while skiing. The ball 16 in the middle of the exhaust pipe 14 sways during skiing without interfering with exhaust. When the user's speed increases and the Venturi effect's attraction is strong enough to overcome the weight of the ball 16, the ball 16 is drawn upward and blocks the exhaust pipe 14, preventing the user's eyes from drying out and breathing difficulties caused by excessive exhaust from the exhaust pipe 14 at high speeds.

[0043] During skiing, the micro wind turbines 13 on both sides of the helmet body 1 rotate and generate electricity driven by high-speed airflow. After being rectified by the PLC components, the generated electricity is supplemented to the power supply 4, effectively increasing the usage time of the equipment while reducing dependence on external energy supplements.

[0044] After work: turn off the power switch 4, rotate the goggles 3 upwards, loosen the fixing strap 2, take off the helmet body 1 and place it on the charging station for charging.

[0045] Example 2:

[0046] refer to Figure 8 Unlike the first embodiment, the front end of the mounting bracket 12 is shaped like a bell that tapers from the front of the helmet toward the rear, and the micro-wind generator 13 is horizontally fixed behind the small opening of the bell. During skiing, the bell-shaped mounting bracket 12 further accelerates the airflow, allowing the blades of the micro-wind generator 13 to rotate at a higher speed, thereby generating more electricity to supplement the power source 4 and extend the operating time of the electric heating element 5.

[0047] Functions and implementation processes not described in this embodiment are the same as those in the first embodiment, so they will not be described in detail.

[0048] Both the first and second embodiments can provide anti-shielding treatment for the goggles 3 during skiing. In the second embodiment, the micro-wind turbine 13 generates more power, so the electric heating element 5 has a longer working time than that of the first embodiment. However, the fixing frame 12 in the second embodiment is in the shape of a trumpet, which accelerates the airflow passing therethrough while also increasing the resistance of the user when skiing, affecting the user's skiing experience.

[0049] The above two embodiments are merely examples among the many embodiments of the present invention. Various changes are possible without violating the principles of the present invention. The embodiments produced by those skilled in the art who modify the present invention without creative work also fall within the scope of protection of the present invention.
