[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0022] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied to a helmet.

[0023] With the rapid development of the field of smart wearables, helmets, as an important part of cycling safety, are increasingly in need of intelligent transformation. However, in the current status of helmet technology, although there are some helmets on the market that have integrated basic intelligent functions, such as built-in Bluetooth headsets and providing intelligent navigation services, there are still obvious shortcomings in the deep integration and information interaction with travel tools such as electric power-assisted bicycles. Specifically, the helmets on the current market generally adopt an isolated electronic system architecture, lacking standardized communication interfaces and protocol support between the main body of the electric power-assisted bicycle. This situation makes it impossible for the helmet to obtain key status information of the electric power-assisted bicycle in real time, such as driving speed, remaining power, fault alarm, etc., and it is also impossible to accurately transmit the rider's instructions or personalized needs back to the electric power-assisted bicycle. In addition, the helmet is also unable to expand its intelligent functions. For example, the limitations of intelligent voice interaction and the monotony of information display methods have failed to fully meet the rider's pursuit of a higher level of convenience, safety and personalized riding experience.

[0024] Based on this, an embodiment of the present application provides an HMD smart helmet, which aims to improve riding safety and convenience.

[0025] See also Figure 1 , Figure 1 This is one of the structural diagrams of an HMD smart helmet provided in an embodiment of the present application. Figure 1 As shown in , one of the structural schematic diagrams of the helmet provided in an embodiment of the present application includes: a helmet body 100, goggles 110, a transmission module 121, an optical waveguide lens 111, and a projection module 112.

[0026] Among them, the HMD (Helmet Mounted Display) uses multiple cameras outside the helmet to capture images from different directions, and through advanced optical sensors and computer technology, converts these images into synthetic images in the wearer's field of view in real time. A visible opening is provided at the front of the helmet body 100, and a neck opening is provided at the bottom of the helmet body 100.

[0027] The goggles 110 are arranged at the visible opening of the helmet body 100, and the two ends of the goggles 110 are movably connected to the two sides of the visible opening of the helmet body 100, wherein the goggles 110 are located in front of the eyes of the wearer of the helmet when in use, and can protect the wearer's eyes from damage by external objects such as wind, sand, and flying insects.

[0028] The transmission module 121 is disposed at the top of the inner cavity of the helmet body 100 and is used to receive projection information transmitted by the onboard domain controller of the power-assisted vehicle, such as navigation information, vehicle status information, etc.

[0029] The optical waveguide lens 111 is a visual lens based on optical waveguide technology, which can be monocular-single projection, or binocular-dual projection. The material can be resin, glass, silicon carbide, etc., and is integrated on the goggles 110.

[0030] As an example, the optical waveguide function can be processed in the lens of the goggles 110, and the optical waveguide lens 111 and the lens of the goggles 110 are combined into one, and the optical waveguide lens 111 is arranged on the inner side of the goggles lens near the eyes, and supports multiple groups of optical waveguide arrays, which are responsible for guiding the projection information in the form of visible light images to the eyes of the wearer. Its working principle is based on the diffraction effect of light. Through the designed optical waveguide structure, the light is propagated along a specific path inside the lens, and finally forms a clear image in front of the wearer's eyes. Among them, the optical waveguide lens 111 can be made thinner and lighter, making the entire helmet lighter and more comfortable to wear. By optimizing the optical waveguide structure, the scattering and loss of light can be reduced, thereby improving the clarity of the image and ensuring that the wearer can view high-quality images.

[0031] The projection module 112 is responsible for projecting the projection information received from the transmission module 121 onto the light waveguide lens 111. The projection module 112 is usually arranged at the side of the goggles 110 so as to accurately project the light onto the light waveguide lens 111. The projection module 112 can receive the projection information from the transmission module 121 and convert it into a light signal suitable for display by the light waveguide lens 111. Through precise optical design and calibration, the projection module 112 can accurately project the light onto a specific position of the light waveguide lens 111 to ensure the correct display of the image.

[0032] In a preferred example of this application, Figure 2As shown in the second structural schematic diagram of the helmet provided in the embodiment of the present application, it also includes: a first monocular waveguide lens 1111, a second monocular waveguide lens 1112, a first projection module 1121 and a second projection module 1122.

[0033] The first monocular waveguide lens 1111 is connected to the first projection module 1121, and the second monocular waveguide lens 1112 is connected to the second projection module 1122, wherein the first projection module 1121 and the second projection module 1122 are respectively arranged on both sides of the visible opening of the helmet, and the first monocular waveguide lens 1111 and the monocular second waveguide lens 1112 are respectively integrated at the positions of the goggles corresponding to the eyes of a person in the use state.

[0034] In a preferred example of this application, Figure 3 As shown in the third structural diagram of the helmet provided in the embodiment of the present application, it also includes: a power module 131, a charging interface 132, a reserved interface 133, a camera 134, a microphone 135, and a communication module 136.

[0035] The power module 131 is disposed at the bottom of the inner cavity away from the goggles 110 . The power module 131 is electrically connected to the projection module 112 and is used to supply power to the projection module 112 and the transmission module 121 .

[0036] The power module 131 includes a battery and a wireless charging coil. The wireless charging coil is electrically connected to the battery for wirelessly charging the battery.

[0037] One end of the charging interface 132 is connected to the transmission module 121 , and the other end of the charging interface 132 is used to connect to an external power source to supply power to the projection module 112 and the transmission module 121 .

[0038] The reserved interface 133 is disposed at the edge of the bottom of the inner cavity and is connected to the projection module 112 , and is used to receive projection information transmitted by the vehicle-mounted domain controller through a hard line when the transmission module 121 is unavailable.

[0039] The camera 134 is disposed at the center below the visible opening of the helmet, and is used to capture the eye movement data of the wearer of the helmet, and send the eye movement data to the vehicle-mounted domain controller, so that the vehicle-mounted domain controller determines the driving status of the driver based on the eye movement data.

[0040] The transmission module 121 includes a helmet domain controller, which is configured to: receive projection information transmitted by the vehicle-mounted domain controller of the power-assisted vehicle and eye movement data captured by the camera 134, so as to determine the state of the wearer of the helmet based on the eye movement data, wherein, when the wearer is in a fatigue state, a warning prompt is projected onto the optical waveguide lens 111 through the projection module 112 to warn the wearer.

[0041] The microphone 135 is arranged at the side below the visible opening of the helmet, and is used to obtain voice information and send the voice information to the vehicle-mounted domain controller of the power-assisted vehicle, so that the vehicle-mounted domain controller executes the instructions corresponding to the voice information according to the voice information.

[0042] The communication module 136 is disposed in the middle of the inner cavity and is connected to the microphone 135 for communicating with the cloud server via the microphone 135 .

[0043] As an example, the helmet may also include: a speaker, a flashing light, a coding screen, a temperature sensor, and an electromyography sensor.

[0044] Specifically, the speakers are arranged in the inner cavity at both sides of the human ear for playing voice prompts, music and the like.

[0045] The flashing light is set above the visible area to improve the wearer's visibility at night or in complex environments, effectively preventing potential safety risks.

[0046] The coding screen is set on the outer surface of the helmet to display the status information, power, connection status, etc. of the helmet.

[0047] The temperature sensor is used to receive a temperature signal of the wearer, and the temperature sensor is arranged at the inner side of the neck opening of the helmet.

[0048] The myoelectric sensor is used to receive the myoelectric signal of the wearer, and the myoelectric sensor is arranged in the inner cavity of the helmet.

[0049] As an example, the helmet domain controller can identify the driver's driving status in the following ways: when the eye movement frequency identified according to the eye movement data is lower than the preset frequency, the eye movement data is determined to be normal information; when the eye movement frequency identified according to the eye movement data is not lower than the preset frequency, the eye movement data is determined to be abnormal information; when the skin temperature value identified according to the temperature signal is lower than the preset temperature value, the temperature signal is determined to be normal information; when the skin temperature value identified according to the temperature signal is not lower than the preset temperature value, the temperature signal is determined to be abnormal information; when the voltage value identified according to the electromyography signal is lower than the preset voltage value, the temperature signal is determined to be normal information; when the voltage value identified according to the electromyography signal is not lower than the preset voltage value, the temperature signal is determined to be abnormal information.

[0050] Among them, when the eye movement data, temperature signal and temperature signal are all normal information, it is determined that the driver is in a normal driving state; when at least one of the eye movement data, temperature signal and temperature signal is abnormal information, it is determined that the driver is in a fatigue driving state.
