Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to an outdoor smart helmet system with long battery life and multiple power supply methods. Background Technology

[0002] Existing outdoor smart helmets have significant technical deficiencies in energy supply, making it difficult to meet the needs of long-term outdoor use, which has become the core issue restricting their development and popularization.

[0003] Currently, most outdoor smart helmets on the market use a single lithium battery power supply mode. Due to the limited energy supply method and the limitation of battery capacity, the standby and working time of the device is short. For users who need to ride outdoors or trek through the wilderness for a long time, the frequent charging operation seriously affects the user experience. In the wild environment where there are no external charging conditions, the smart functions are easily rendered unusable due to the depletion of power, resulting in the loss of protection and interactive value.

[0004] To improve battery life, some developers have tried to increase battery capacity, but this directly increases the overall weight of the helmet, reduces wearing comfort, and violates the lightweight design principle of outdoor smart devices. Some products have also tried to add external charging ports, but this cannot solve the core pain point of no charging facilities in the wild.

[0005] Meanwhile, the existing structural design of outdoor smart helmets does not make full use of renewable energy in outdoor scenarios. The wind energy generated during outdoor cycling, the solar energy in the natural environment, and the temperature difference energy formed between the human head and the external environment are not effectively utilized, resulting in energy waste and missing the effective way to improve the device's battery life.

[0006] Therefore, developing a long-lasting outdoor smart helmet system that can fully utilize outdoor renewable energy, achieve multiple energy supply pathways, and take into account lightweight and integrated design, in order to solve the technical problems of short battery life, single energy supply, and unreasonable structural design of existing products, has become an urgent technical need to be addressed in this field.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Please see Figures 1 to 6 As shown, the embodiments of the present invention provide the following technical solutions:

[0070] As an embodiment of the present invention:

[0071] This invention relates to a long-lasting, multi-source power supply outdoor smart helmet system, comprising:

[0072] The helmet body is 100mm thick and made of lightweight, high-strength composite materials;

[0073] The helmet body 100 integrates a wind power supply module 200 and a power management system 500.

[0074] The wind power module 200 is installed at the center of the top of the helmet shell and is used to convert the wind energy generated by the user during outdoor sports into electrical energy to replenish the helmet system with wind power.

[0075] The power management system 500 is embedded in the reserved cavity on the rear side of the helmet shell to receive the electrical energy converted by each power supply module and to store and distribute electrical energy for the helmet system.

[0076] The power management system 500 includes a power management circuit board 501, which adopts a miniaturized and integrated circuit board design. The power management circuit board 501 is equipped with a unidirectional rectifier bridge 502, a low-voltage linear regulator 503, a miniature lithium polymer energy storage battery 504, a multi-channel voltage / current sensor 505, and a control chip 506.

[0077] In this embodiment, all hardware components are surface-mount devices, effectively reducing the size of the circuit board and adapting to the installation space of the helmet's integrated cavity; the intelligent control chip is a low-power microcontroller used to achieve unified scheduling of all hardware components.

[0078] The power management circuit board 501 is mounted in an integrated cavity pre-set on the rear side of the helmet body 100 via a fixing post;

[0079] The output wires of the wind power supply module 200 are respectively connected to the corresponding power input interfaces on the power management circuit board 501;

[0080] Connect the power input wire of the helmet's functional power module to the power output interface on the power management circuit board 501.

[0081] In this embodiment, the functional power modules include an AR display module, a positioning module, and a lighting module.

[0082] The working principle of the power management system 500 is as follows:

[0083] The electrical energy generated by each power supply module is first transmitted to the unidirectional rectifier bridge 502 of the power management system 500 to realize the rectification of electrical energy, converting the unstable DC power into stable DC power, and preventing voltage fluctuations from damaging subsequent hardware.

[0084] The rectified electrical energy is transmitted to the low-voltage linear regulator 503, which stabilizes the voltage of the electrical energy at the rated operating voltage of the corresponding functional power module of the helmet, ensuring the consistency of the power supply voltage.

[0085] The regulated electrical energy is divided into two transmission paths:

[0086] When the remaining power of the micro lithium polymer energy storage battery 504 is detected to be insufficient, the power is preferentially transferred to the micro lithium polymer energy storage battery 504 for storage.

[0087] When the micro lithium polymer energy storage battery 504 is fully charged, the electrical energy is directly transmitted to the power output interface to power the helmet's functional power modules.

[0088] The wind power supply module 200 consists of a micro wind turbine 201, a rotating impeller 202, a support 203, and a power conversion interface 204;

[0089] The wind power module 200 is rotatably connected to the helmet body 100, and the helmet body 100 is provided with a corresponding groove 205 for storing the wind power module 200.

[0090] When needed, the wind power module 200 is rotated to the unfolded state to put it in the working position to provide wind power.

[0091] When not in use, the wind power module 200 is rotated in the opposite direction so that it is stored in the groove 205 of the helmet body 100.

[0092] A rotating seat 206 is fixedly connected to the front side of the groove 205, and the rotating seat 206 is rotatably connected to the bottom of the bracket 203 through a rotating shaft connecting rod 207.

[0093] One end of the rotating shaft connecting rod 207 passes through one side of the rotating seat 206 and is fixedly connected to a gear 208. One side of the rotating seat 206 is slidably connected to an arc-shaped toothed rail 209 through a limiting sliding assembly, and the gear 208 meshes with the arc-shaped toothed rail 209 for transmission.

[0094] In this embodiment, the bracket 203, the rotating shaft connecting rod 207, and the gear 208 are integral injection molded structures;

[0095] One end of the arc-shaped toothed rail 209 is fixedly connected to a pull rope 210, and one side of the rotating seat 206 is fixedly connected to a spring limit buckle 211, with the pull rope 210 passing through the spring limit buckle 211.

[0096] A spring 212 is provided between the spring limit buckle 211 and one end of the arc-shaped toothed rail 209, and the spring 212 is sleeved on the outer surface of the pull rope 210.

[0097] The bottom of the bracket 203 is fixedly connected to the middle of the rotating shaft connecting rod 207, and the rotating seat 206 is rotatably connected to the rotating shaft connecting rod 207.

[0098] The limiting sliding assembly consists of a limiting slider 213 fixedly connected to one side of the rotating seat 206 and a limiting slide opening 214 opened on one side of the arc-shaped toothed rail 209, and the limiting slider 213 and the limiting slide opening 214 limit each other to slide.

[0099] In this embodiment, the height of the bracket 203 is 4-5cm, which ensures effective rotation space for the rotating impeller without increasing the overall wind resistance of the helmet.

[0100] The helmet body 100 is provided with a snap fastener assembly on the chin strap;

[0101] The latch assembly consists of a latch body 215 with a side slot, a mating part 216, and a limiting housing 217;

[0102] In this embodiment, the two ends of the chin strap are respectively connected to the connecting parts pre-set on both sides of the bottom of the helmet body 100;

[0103] The limiting shell 217 is fixedly connected to the connecting part on one side of the helmet body 100, and the two sides inside the limiting shell 217 are slidably connected to the limiting sliding plate 219 through the limiting sliding post 218. The lower part of the limiting sliding post 218 is fitted with a second spring 220, and the second spring 220 is placed below the limiting sliding plate 219.

[0104] The other end of the pull rope 210 passes through the limiting housing 217 and is fixedly connected to the middle part above the limiting slide post 218;

[0105] In this embodiment, the pull rope 210 is arranged along the inner side of the helmet body 100 and can slide relative to the inner side of the helmet body 100, and the tension of the pull rope 210 is moderate.

[0106] The middle part below the limiting sliding plate 219 is connected to the mating part 216 by a braided rope 221;

[0107] A through slot 222 is provided in the middle of the surface of the latch body 215, and a T-shaped handle 223 is fixedly connected to the middle of the surface of the mating part 216.

[0108] In this embodiment, the mating part 216 and the T-shaped handle 223 are integral injection molded structures;

[0109] The mating part 216 is detachably mated with the latch body 215, and the T-shaped handle 223 is adapted to the position of the through slot 222;

[0110] In this embodiment, the insertion depth of the latch body 215 is greater than the length of the mating part 216; when the mating part 216 is inserted into the latch body 215 and locked, the mating part 216 is completely housed inside the latch body 215, and a space with a preset distance is reserved at the insertion opening of the latch body 215.

[0111] The preset spacing ensures that the wind power module 200, which is stored in the corresponding groove of the helmet body, can rotate smoothly to the unfolded state.

[0112] The micro wind turbine 201 is mounted on the top of the support 203, and its rotor shaft is coaxially and fixedly connected to the central shaft of the rotating impeller 202.

[0113] The power conversion interface 204 is electrically connected to the stator winding of the micro wind turbine 201 and is connected to the input terminal of the power management system 500 via a waterproof conductive cable.

[0114] In this embodiment, the rotating impeller 202 adopts a three-bladed lightweight structure with curved blades made of high-strength engineering plastics. It can rotate at low wind speeds and is suitable for the relative airflow generated during outdoor cycling and wilderness exploration.

[0115] The working principle of the wind power supply module is as follows:

[0116] When using the wind power module 200, first put the helmet body 100 on the user's head, then take the T-shaped handle 223 and align the T-shaped handle 223 with the through slot 222 so that the mating part 216 is inserted into the locking body 215 and locked.

[0117] When the mating part 216 is locked with the locking body 215, the insertion port of the locking body 215 and the limiting housing 217 press against each other.

[0118] Meanwhile, the limiting sliding plate 219, which is connected to the mating part 216 via the braided rope 221, slides down in the limiting housing 217, thereby pulling the pull rope 210.

[0119] As the rope 210 moves, it drives the arc-shaped toothed rail 209 to move, and the gear 208 meshes with the arc-shaped toothed rail 209 to drive the rotation, causing the rotating shaft connecting rod fixedly connected to the gear 208 to rotate, thereby causing the bracket 203 to flip and stand on the top of the helmet body 100.

[0120] When a user wears the helmet for outdoor cycling, relative airflow is generated around the helmet. The airflow drives the rotating impeller 202 to rotate around the drive shaft. The rotation of the rotating impeller 202 drives the rotor of the micro wind turbine 201 to rotate at high speed. The rotor moves by cutting magnetic field lines in the stator magnetic field of the generator, realizing the conversion of wind energy into mechanical energy and then into electrical energy. The electrical energy generated by the micro wind turbine 201 is transmitted to the power management system 500 through waterproof conductive cables hidden in the conductor channel to replenish the helmet's energy.

[0121] This embodiment leverages the lightweight design of the helmet body 100 to integrate a wind power module 200 and a power management system 500. It achieves low-wind-speed power generation through a micro wind turbine 201 and a rotating impeller 202. The surface-mount components 502-506 on the power management circuit board 501 are compact, and the locking buckles 215-223 are linked to the wind power module; locking it in place automatically deploys the power supply. The module can be stored in the recess 205 without adding weight or wind resistance, continuously powering modules such as AR displays, significantly improving outdoor battery life, and making it suitable for cycling and exploration scenarios.

[0122] As a second embodiment of the present invention:

[0123] In specific implementation, compared with Embodiment 1, the only difference between the technical solution of this embodiment and Embodiment 1 is that in this embodiment, the helmet body 100 is also integrated with a photovoltaic power supply module 300;

[0124] The output wires of the photovoltaic power supply module 300 are connected to the corresponding power input interface on the power management circuit board 501.

[0125] The photovoltaic power supply module 300 is attached to the outer curved surface of the helmet shell and is used to convert solar energy into electrical energy to provide solar power for the helmet system.

[0126] The photovoltaic power supply module 300 is composed of a flexible photovoltaic panel 301, an invisible edge strip 302, a scratch-resistant and wear-resistant protective film 303, and a photovoltaic junction box 304.

[0127] In this embodiment, the flexible photovoltaic panel 301 is custom-cut according to the curved shape of the outer surface of the helmet body;

[0128] The scratch-resistant and wear-resistant protective film 303 is made of high-transmittance PET material and is applied to the outer surface of the photovoltaic panel;

[0129] It does not affect the sunlight exposure and can prevent the photovoltaic panels from being scratched or worn during outdoor use.

[0130] The flexible photovoltaic panel 301 is attached to the outer surface of the helmet body 100, and the invisible edge strip 302 is engaged with the edge of the flexible photovoltaic panel 301 and the invisible edge strip 302 is engaged with the outer surface of the helmet body 100.

[0131] To secure the edges of the photovoltaic panels and prevent them from warping or falling off during outdoor use;

[0132] The photovoltaic junction box 304 is fixedly connected to the rear side of the helmet body 100;

[0133] In this embodiment, the power output wire of the flexible photovoltaic panel 301 is directly inserted into the photovoltaic junction box 304. The terminal crimping and line bus fixing are completed inside the photovoltaic junction box 304. After the circuit is regulated inside the photovoltaic junction box 304, a unified output wire is led out from the photovoltaic junction box 304 and then connected to the wire channel inside the helmet, and finally connected to the power management system 500.

[0134] The working principle of the photovoltaic power supply module 300 is as follows:

[0135] When there is sunlight outdoors, sunlight shines through the high-transmittance scratch-resistant and wear-resistant protective film 303 onto the flexible photovoltaic panel 301, which uses the photovoltaic effect to directly convert light energy into electrical energy.

[0136] Because the photovoltaic panels adopt a customized curved surface design and the cells are distributed, no matter which angle the sunlight shines from, there is a corresponding cell to capture the light energy, effectively improving the utilization rate of light energy; even in environments with weak sunlight, such as cloudy days, the photovoltaic panels can still generate a small amount of electricity to continuously replenish the helmet system.

[0137] The electrical energy generated by the flexible photovoltaic panel 301 is collected through the photovoltaic junction box and then transmitted to the power management system 500 to realize the storage and utilization of electrical energy.

[0138] Example 2, based on Example 1, adds a photovoltaic power supply module 300. A flexible photovoltaic panel 301 is fitted to the curved surface of the helmet, a scratch-resistant and wear-resistant protective film 303 balances light transmission and protection, and an invisible edge strip 302 prevents edge warping. Together with the wind power supply module 200, it provides dual protection. Power is collected through the photovoltaic junction box 304, adapting to different lighting conditions, improving power supply stability and versatility, extending battery life, and meeting the high endurance requirements of long-term outdoor work and exploration.

[0139] As an embodiment of the present invention:

[0140] In specific implementation, compared with Embodiment 1 and Embodiment 2, the technical solution of this embodiment is to combine the solutions of Embodiment 1 and Embodiment 2. The only difference between the technical solution of this embodiment and Embodiment 1 and Embodiment 2 is that in this embodiment, the helmet body 100 also integrates a temperature difference power supply module 400.

[0141] The output wire of the temperature difference power supply module 400 is connected to the corresponding power input interface on the power management circuit board 501.

[0142] The temperature difference power supply module 400 is divided into an inner layer and an outer layer, which are respectively set in corresponding areas on the inner and outer sides of the helmet shell; it is used to convert the temperature difference between the human head and the external environment into electrical energy to provide temperature difference power to the helmet system.

[0143] The thermoelectric power supply module 400 is composed of several miniature semiconductor thermoelectric generators 401, thermally conductive silicone pads 402, and heat dissipation aluminum fins 403.

[0144] The thermally conductive silicone pad 402 is attached to the hot end of the micro semiconductor thermoelectric generator 401 to improve the heat conduction efficiency between the generator and the human head.

[0145] The heat dissipation aluminum fin 403 is attached to the cold end of the micro semiconductor thermoelectric generator 401 to improve the heat exchange efficiency between the generator and the outdoor environment.

[0146] In this embodiment, the semiconductor thermoelectric generator utilizes the Seebeck effect to directly convert temperature difference into electrical energy, making it a highly efficient and reliable green energy device. The micro semiconductor thermoelectric generator 401 is made of bismuth telluride-based composite material and has an ultra-thin square structure; this is existing technology and will not be described in detail.

[0147] The micro-semiconductor thermoelectric generator 401 is embedded in the inner side of the helmet body 100, with the hot end of the micro-semiconductor thermoelectric generator 401 facing the inner side of the helmet and in contact with the human head; the cold end of the micro-semiconductor thermoelectric generator 401 faces the outer side of the helmet and is in contact with the outdoor environment.

[0148] The power output wires of each of the micro-semiconductor thermoelectric generators 401 are introduced into the wire channel inside the helmet, and all the micro-semiconductor thermoelectric generators 401 are connected in parallel and then connected to the power management system 500.

[0149] The working principle of the temperature difference power supply module 400 is as follows:

[0150] During outdoor activities, the user's head continuously generates heat. There is a natural temperature difference between the outdoor environment temperature and the temperature of the human head. This temperature difference creates a continuous temperature gradient between the hot and cold ends of the thermoelectric generator. The generator uses the Seebeck effect to directly convert the temperature difference into electrical energy.

[0151] Existing outdoor smart wearable devices do not have a thermoelectric power supply structure. This embodiment utilizes the natural temperature difference between the human head and the outdoor environment to achieve energy recovery and utilization through semiconductor thermoelectric power generation technology. Even in outdoor environments with no wind and no sunlight, it can still provide continuous low-power power to the helmet system.

[0152] Example 3, combining with the previous scheme, adds a thermoelectric power supply module 400. A micro-semiconductor thermoelectric generator 401 generates electricity using the temperature difference between the human body and the environment, while a thermally conductive silicone pad 402 and a heat dissipation aluminum fin 403 improve efficiency. These three types of power supply modules complement each other, filling the gap in scenarios without wind or sunlight. The power management system 500 intelligently distributes power, achieving green energy recovery. The compact structural design does not affect wearing comfort, completely solving outdoor battery anxiety and adapting to various extreme environments.

[0153] As an embodiment of the present invention:

[0154] In specific implementation, compared with Embodiment 1, Embodiment 2 and Embodiment 3, the difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is only that in this embodiment, the technical solution is to combine the solutions of Embodiment 1, Embodiment 2 and Embodiment 3.

[0155] In this embodiment, the wind power module 200, photovoltaic power module 300, temperature difference power module 400, and power management system 500 are physically integrated.

[0156] The busbars of the wind power module 200, photovoltaic power module 300, and temperature difference power module 400 are respectively connected to the corresponding power input interfaces on the power management circuit board 501; and the power output terminals of each power module are electrically connected to the power input terminals of the power management system 500 through waterproof conductive cables.

[0157] In this embodiment, the waterproof conductive cables corresponding to each power supply module are set in the pre-set wire channels inside the helmet body 100, and the connection points between the power output end and the power input end are sealed and insulated to adapt to complex outdoor use environments such as rain, high temperature, low temperature, and sandstorm.

[0158] Example 4 integrates three types of power supply modules—wind power, photovoltaic power, and thermoelectric power—with the power management system 500 to form a multi-path power supply closed loop. The wiring is concealed within the helmet body's wiring channel 100, with sealed and insulated connection points, adaptable to complex outdoor environments. Multiple modules work together to replenish power, which is efficiently stored and distributed via the power management circuit board 501, maximizing the continuity and stability of power supply, completely eliminating battery life limitations, and meeting the needs of long-duration, high-intensity outdoor use.
