Description

Technical Field

[0001] This utility model relates to the field of helmets, and more specifically, to an image projection component for a helmet and a helmet. Background Technology

[0002] As a protective device for the head, helmets have undergone a long period of development and have evolved into various types, widely used in different fields. A helmet is a personal protective equipment used to protect the head from physical injuries (such as impacts, punctures, electric shocks, etc.) or environmental hazards (such as high temperatures, radiation, and chemicals). Its core function is to reduce the risk of head injury by dispersing impact force through the outer shell, absorbing energy through the cushioning layer, and distributing pressure through the inner lining that fits snugly against the head.

[0003] When using existing helmets, cyclists wear them on their heads, and the helmet's obstruction forces them to view the outside world only through the helmet's glass. This means that when cyclists need to see navigation, they have to look down, which is inconvenient and increases the risk of danger while riding. Utility Model Content

[0004] One objective of this invention is to provide a helmet image projection component and a new technical solution for the helmet.

[0005] According to a first aspect of the present invention, a helmet image projection component is provided, comprising: a projection mechanism, the projection mechanism including a high-brightness LCD module, the high-brightness LCD module being connected to a projection system via wires, the high-brightness LCD module being projected onto a display area via the projection system, the high-brightness LCD module being electrically connected to a PCBA motherboard, and the PCBA motherboard being electrically connected to a camera.

[0006] Preferably, the projection mechanism is equipped with a voice control system, which is electrically connected to the high-brightness LCD module.

[0007] A helmet includes: a helmet body and a helmet image projection assembly. A helmet glass is rotatably mounted on the helmet body. The helmet image projection assembly is mounted on the helmet body. A stabilizing mechanism is provided on the helmet body. The stabilizing mechanism includes a fixing post, which is fixedly connected to the inner wall of the helmet body. A connecting plate is fixedly connected to the bottom end of the fixing post. An assembly bolt is installed inside the connecting plate and is installed inside a high-brightness LCD module.

[0008] Preferably, a limiting cavity is formed inside the helmet body, and a projection system is installed inside the limiting cavity.

[0009] Preferably, a shock-absorbing rubber ring is provided at the connection between the projection system and the limiting cavity.

[0010] Preferably, the helmet glass is rotatably mounted on the surface of the helmet body via a rotating part.

[0011] 1. This utility model utilizes the cooperation of a helmet glass, camera, PCBA motherboard, high-brightness LCD module, projection system, and display area. The high-brightness LCD module displays navigation information and serves as an image source, providing a high-resolution, high-contrast pixel matrix. The projection system projects the navigation information displayed on the LCD screen onto the display area on the helmet glass, allowing cyclists to view the navigation information directly by looking at the display area, avoiding the need to look down at their mobile phones for navigation, making cycling more convenient and safer. The camera on the helmet glass can capture images of the surrounding environment, serving a recording function. It can be used for AR real-scene fusion assistance or as a pedestrian recorder. This helmet enables the high-brightness LCD module to serve as an image source, and the navigation information displayed on the high-brightness LCD module can be projected onto the display area using the projection system, making it easy to view while cycling and improving the practicality and safety of the device.

[0012] 2. This utility model utilizes a combination of a fixing column, connecting plate, mounting bolts, limiting cavity, and shock-absorbing rubber ring. The high-brightness LCD module and projection system are modularly assembled inside the helmet body, allowing for convenient installation and stable use. The projection system is placed inside the limiting cavity for controlled projection, preventing deviations in the projection position caused by vehicle shaking during riding. A shock-absorbing rubber ring is filled at the connection between the projection system and the limiting cavity, providing cushioning and protection against violent shaking, ensuring greater stability during projection within the limiting cavity. This modular design allows for easy assembly and connection of internal components, and provides cushioning during use, preventing vibrations from affecting the projection and improving the device's practicality and stability.
