Description

Technical Field

[0001] This invention relates to the field of cycling assistance devices, and in particular to a helmet and a method for controlling a helmet fan. Background Technology

[0002] With the popularization of cycling and the upgrading of urban commuting needs, helmets, as core equipment that combines protection and comfort, are increasingly focusing on optimizing thermal comfort in their functional iterations. During cycling, obstructed heat dissipation from the head can easily lead to discomfort such as stuffiness and sweating, especially in high-temperature environments or long-distance cycling scenarios. The passive ventilation structure of traditional cycling helmets is no longer sufficient to meet user needs, leading to the emergence of active cooling cycling helmets with fans. However, existing products generally suffer from problems such as functional homogenization and low levels of intelligence. More than 70% of fan helmets still rely on manual on / off control, requiring users to operate them at a distraction while riding, which not only affects cycling safety but also fails to dynamically adjust according to real-time environmental conditions and riding status, resulting in a contradiction between wasted battery life and inadequate heat dissipation. At the same time, the complexity of cycling scenarios (such as changes in speed, fluctuations in ambient temperature and humidity, and differences in wearing conditions) further highlights the limitations of traditional manual control modes, urgently requiring the development of adaptive automatic start-stop technology to match actual usage needs.

[0003] The shortcomings and pain points of existing related technologies: Inflexible control methods and poor user experience: Most mainstream fan-equipped helmets on the market currently use mechanical buttons or single trigger switches, lacking dynamic sensing capabilities. Although some helmets integrate fan devices, their control logic is simple—either based solely on the visor's opening / closing status and a fixed wind speed threshold (such as in low-speed anti-fog scenarios), or relying on a single humidity sensor for triggering, failing to adapt to dynamic changes in multiple parameters such as vehicle speed, ambient temperature, and head heat load during riding; manual control modes also pose operational safety hazards, as adjusting the fan while riding can easily lead to distraction, which does not comply with riding safety regulations. Lack of functional synergy and prominent performance shortcomings: The fans of existing products are not well adapted to cycling scenarios. On the one hand, the fan start-stop and battery life management are disconnected, with 62% of users reporting that the actual battery life is far lower than the advertised value, and ineffective start-stop exacerbates energy waste. On the other hand, the fan layout is unreasonable (such as external blades affecting visibility and uneven airflow distribution), and there is a lack of coordinated design with the protective structure and ventilation system of cycling helmets. 57% of the products have a negative impact on the long-term user experience due to the pressure of wearing them and excessive operating noise (55-65 decibels). Low level of intelligence and disconnect from industry trends: Intelligent cycling equipment has become a core development direction, with AI-driven adaptive ventilation and biometric monitoring functions gradually becoming market hotspots. However, the technological innovation of existing fan helmets has stagnated at the basic combination of "hat + fan," lacking real-time perception and intelligent decision-making capabilities for riding status and environmental data, which contradicts the industry's trend towards "proactive comfort management." Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a new helmet and a method for controlling the helmet fan.

[0005] This invention provides a method for controlling a helmet fan, wherein the helmet is worn by a user while cycling, and the helmet includes a fan, an infrared sensor, and an accelerometer. The method includes: determining the wearing state of the helmet using the infrared sensor data; detecting the motion state of the helmet using the accelerometer after determining that the helmet is being worn; activating the fan when the helmet is stationary; and stopping the fan when the helmet is moving.

[0006] In one embodiment, the step "determining the wearing status of the helmet using infrared sensing data" includes: detecting the wearing status of the helmet using infrared sensing data at fixed time intervals.

[0007] In one embodiment, the fixed time period is 100ms.

[0008] In one embodiment, the method further includes: if the infrared sensor data determines that the helmet is not being worn, then stopping the fan.

[0009] In one embodiment, the method further includes: after the fan has been operating for a predetermined time, determining the wearing status of the helmet using the infrared sensor data.

[0010] The present invention also provides a helmet for a user to wear while cycling, comprising: A fan; an infrared sensor for determining the wearing status of the helmet; an accelerometer for detecting the motion state of the helmet; and a processing module for activating the accelerometer when the user is wearing the helmet, and controlling the start and stop of the fan according to the motion state of the helmet, wherein the fan is activated when the helmet is stationary and stopped when the helmet is moving.

[0011] In one embodiment, the processing module is further configured to detect the wearing status of the helmet using the infrared sensing data at fixed time intervals.

[0012] In one embodiment, the fixed time period is 100ms.

[0013] In one embodiment, the processing module is further configured to determine, based on the infrared sensor data, that the helmet is not being worn, and to stop the fan.

[0014] In one embodiment, the processing module is further configured to determine the wearing status of the helmet using the infrared sensor data when the fan has been operating for a predetermined time.

[0015] Compared with the prior art, the helmet and the method for controlling the helmet fan of the present invention determine the wearing status of the helmet through an infrared sensor and detect the motion status of the helmet through an accelerometer, thereby controlling the start and stop of the fan. No manual operation by the user is required, and the core experience can be easily upgraded: say goodbye to stuffiness and double the comfort.

[0016] Precise cooling to adapt to environmental changes. When users wear helmets while riding electric bikes or motorcycles, the fan automatically stops, allowing users to cool down using natural wind. When users wear helmets but are not riding, the fan automatically turns on to alleviate the stuffiness in summer, high-temperature work, or long-term wearing scenarios (such as riding, construction sites, and food delivery).

[0023] Please refer to Figure 1 , Figure 1 The image shown is a usage scenario diagram of the helmet provided in one embodiment of the present invention.

[0024] In this embodiment, the user wears a helmet while riding an electric bicycle, motorcycle, etc. This ensures the user's safety during riding, improves the safety factor of driving, and also enhances the user's comfort and experience by using a fan.

[0025] Please refer to Figure 2 , Figure 2 The diagram shown is a schematic diagram of a helmet provided in one embodiment of the present invention.

[0026] Figure 3 for Figure 2A schematic diagram of the fan in one embodiment. In this embodiment, the fan is located at the rear of the helmet, at the back of the wearer's head when worn, which is the area that sweats the most and is the hottest. The helmet's built-in fan intake, air duct, and air outlet, together with the small holes on the top of the inner side of the helmet, absorb heat, which is then blown out through the ventilation openings on both sides of the neck, completing this closed-loop air intake system. This active air intake creates an airflow, resulting in a refreshing feeling of "cool air blowing on the scalp." Existing helmets, on the other hand, can only breathe through ventilation holes (such as small holes on the top / side), which is passive. The airflow can only: skim over the surface of the helmet and has difficulty penetrating the inner lining (especially the sweat-absorbing sponge or fleece material); it can only remove heat from the outside of the helmet and cannot reach the "enclosed areas" such as the top of the head, the back of the head, and behind the ears.

[0027] Please refer to Figure 4 , Figure 4 The diagram shows a schematic of a helmet module according to one embodiment of the present invention. The present invention also provides a helmet for use by a user while cycling, comprising: a fan 102, an infrared sensor 104, an acceleration sensor 106, a processing module 108, and a storage module 110. The storage module 110 is used to store code executed by the processing module 104.

[0028] In this embodiment, the infrared sensor 104 is used to determine the wearing status of the helmet.

[0029] In this embodiment, the infrared sensor 104 is one of the core components for realizing intelligent control. Utilizing the principle of infrared thermal radiation detection, it can perform multiple key functions without contact or interfering with the wearing experience. Specifically, its functions revolve around three core requirements: precise temperature control, intelligent interaction, and safety protection. The core function of the infrared sensor 104 is to accurately sense the temperature inside the helmet to determine whether the helmet is being worn. It can detect the air temperature inside the helmet 100 or the surface temperature of the scalp non-contactly (avoiding interference from sweat and sensor damage caused by direct contact with the scalp). Compared with ordinary thermistors, the infrared sensor 104 has more accurate temperature measurement, faster response speed, and is not affected by the external temperature of the helmet 100's outer shell.

[0030] The infrared sensor 104 can identify the thermal radiation characteristics of the human body (the human body temperature is about 36-37℃, and it will continuously emit infrared light of a specific wavelength). When the user wears the helmet, the infrared sensor 104 detects the human body's thermal radiation, and the processing module 108 controls the accelerometer 106 to work.

[0031] This feature not only avoids wasting battery power due to forgetting to turn off the helmet, thus extending its battery life, but also eliminates the need for manual switching, improving ease of use. It is especially suitable for the "turn on when wearing the helmet and turn off when taking it off" usage scenario while cycling.

[0032] In this embodiment, the infrared sensor 104 is a non-contact detection device. It does not need to be embedded in the lining of the helmet 100 or in contact with the scalp. It will not be wetted or corroded by sweat, nor will the detection accuracy be affected by head shaking. At the same time, it is small in size and has low power consumption, and can be easily integrated into the ventilation opening or edge of the helmet 100 without damaging the protective structure and appearance design of the helmet 100.

[0033] In this embodiment, the accelerometer 106 is used to detect the motion state of the helmet.

[0034] In this embodiment, the accelerometer 106 is a key component for sensing the helmet's motion state and realizing safety protection and intelligent interaction. It can detect changes in the helmet 100's acceleration, vibration intensity, and posture. Its core functions are as follows: Recognizes riding status and triggers intelligent speed adjustment / start / stop of fan 102. The accelerometer 106 can accurately capture speed changes, start-stop actions, and road bump levels during riding, thereby optimizing the operating logic of the fan 106 for more efficient and energy-saving cooling. When high-speed riding is detected (stable acceleration and uniform movement trajectory), it indicates that there is sufficient natural wind, and the frequency of fan 106 can be automatically reduced or the fan 106 can be stopped to save power. When low speed / stop / traffic jam is detected (acceleration is 0 or fluctuates frequently), the natural wind is insufficient, so the fan speed is automatically increased by 106 to ensure heat dissipation for the head. When bumpy road conditions are detected (such as severe vibrations from speed bumps or potholes), the speed of fan 106 can be temporarily reduced to reduce abnormal noise caused by vibration and to avoid the sudden changes in airflow affecting the user's experience.

[0035] In this embodiment, the accelerometer 106 and the infrared sensor 104 can form a dual verification to accurately determine whether the helmet 100 is being worn, thus avoiding accidental power-on or forgetting to power it off.

[0036] When the helmet 100 is placed on a table / car basket (stationary state, acceleration is 0), even if the infrared sensor 104 misjudges due to ambient temperature, the acceleration sensor 106 will confirm "no movement" and prevent the fan 102 from starting.

[0037] When the user puts on the helmet 100 and starts riding (continuous motion acceleration is detected), the fan 102 will be fully activated only after the infrared sensor 104 detects human body heat radiation and confirms the "wearing status" twice, thus preventing the helmet 100 from being accidentally turned on when shaken and further extending the battery life.

[0038] In this embodiment, the processing module 108 is used to activate the acceleration sensor 106 when the user is wearing the helmet 100, and to control the start and stop of the fan 102 according to the motion state of the helmet 100.

[0039] In this embodiment, when the helmet 100 is stationary, the processing module 108 activates the fan 102.

[0040] In this embodiment, when the helmet 100 is in a moving state, the processing module 108 stops the fan 102.

[0041] In this embodiment, the processing module 108 is further configured to detect the wearing status of the helmet 100 using the infrared sensor data at fixed time intervals. The infrared sensor data is acquired in real time by the infrared sensor 104.

[0042] In this embodiment, the fixed time period is 100ms.

[0043] In this embodiment, the processing module 108 is further configured to stop the fan 102 when it is determined by the infrared sensor data that the helmet is not being worn.

[0044] In one embodiment, the processing module 108 is further configured to determine the wearing status of the helmet 100 by means of the infrared sensor data when the fan 102 has been operating for a predetermined time.

[0045] In this embodiment, the predetermined time is 100ms.

[0046] Please refer to Figure 5 , Figure 5 The diagram shows a flowchart of a helmet fan control method provided in one embodiment of the present invention.

[0058] When the helmet 100 is stationary, in step S204, the processing module 108 starts the fan 102.

[0059] And when the helmet is in a moving state, in step S206, the processing module 108 stops the fan 102.

[0060] In this embodiment, step S200, "determining the wearing status of the helmet 100 using infrared sensing data", includes: detecting the wearing status of the helmet 100 using infrared sensing data at fixed time intervals.
