Abstract
Description
Technical Field
[0001] This utility model relates to a multifunctional wearable device, and more particularly to an improvement of a modular multifunctional helmet and its module connection device. Background Technology
[0002] Traditional helmets on the market primarily focus on basic safety features. While some multi-functional helmets with integrated features, such as built-in headphones, microphones, and cameras, have emerged in recent years, these products generally employ a design that integrates all functions fixed inside the helmet. This integrated approach has significant drawbacks: if any extended function module malfunctions or is damaged, the entire helmet often needs repair or replacement, resulting in high maintenance costs. Furthermore, the overall design lacks independence between functional modules, preventing flexible replacement or upgrades based on user needs, thus reducing product lifespan and cost-effectiveness. In addition, the integrated design increases manufacturing and R&D costs, limiting the product's market penetration and promotion.
[0003] Meanwhile, these expansion devices are mostly electronic devices, which are prone to damage and malfunction in high-speed and high-vibration environments. Each expansion device requires different installation and connection methods depending on its installation location, which results in extremely high research and development and production costs, as well as many difficulties in research and development and production.
[0004] Therefore, how to achieve flexible disassembly and replacement of extended functions while maintaining the basic safety protection function of the helmet, and ensure the stable operation of each extended function, has become an urgent technical problem to be solved. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings and deficiencies of existing technologies by providing a modular multifunctional helmet and its flexible snap-fit connection device. Through modular design, it enables independent disassembly and replacement of each functional module, thereby significantly reducing maintenance costs and improving the product's economy. It adopts a flexible snap-fit connection method to ensure the firmness and convenience of module installation, effectively improving safety and user experience.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a helmet body 1 and an expansion function module connector 2, the expansion function module connector 2 being flexibly connected to the helmet body 1; a corresponding expansion function module 3 is fixedly connected to the expansion function module connector 2; a flexible connection hole 11 and an expansion module fixing seat 31 are provided at a predetermined position on the helmet body 1, the flexible connection hole 11 being provided with an anti-slip groove 111, the anti-slip groove 111 being one or more; the flexible connection hole 11 being square, circular, or elliptical; the expansion end of the expansion module fixing seat 31 is fixedly connected to the expansion function module 3, the insertion end of the expansion module fixing seat 31 is provided with an anti-slip rib 311, the anti-slip rib 311 being one or more, the anti-slip rib 311 corresponding to the anti-slip groove 111.
[0007] The extended functional module 3 includes a Bluetooth headset module, a helmet camera module, a helmet fan module, a HUD display module, a smart lighting module, a voice assistant module, a walkie-talkie microphone module, a night vision enhancement module, a panoramic camera module, a fatigue detection module, a sports data recording module, a remote monitoring module, and an emergency airbag module. The Bluetooth headset module provides wireless calling, music playback, and navigation voice; the helmet camera module records the riding process and supports live streaming, video recording, and night vision enhancement; the helmet fan module improves head cooling and enhances comfort; the HUD display module provides navigation and information projection; and the smart lighting module includes built-in LED lights, night warning lights, and ambient lighting.
[0008] The expansion module fixing base 31 is made of rigid foam or high-polymer elastic material. After being inserted into the flexible connection hole 11, the expansion module fixing base 31 is secured and prevented from slipping by internal ribs. The high-polymer elastic material has a certain degree of elasticity and wear resistance. During insertion, the expansion module fixing base 31 is inserted and secured under the action of external force. Under the compression of the material itself, it can be firmly inserted and will not fall off or shift even under high-speed movement and vibration.
[0009] The flexible connection hole 11 and the expansion module mounting base 31 can also be connected by threads. Depending on the actual application scenario, different connection methods can be selected, including threaded connection, snap-fit connection, slide rail connection, slot connection, and magnetic connection. A standard snap-fit design is used, allowing the module to be fixed and removed by pressing or rotating the snap-fit. The module slides in or out along a preset slide rail or slot, forming a stable fixation with the inside of the helmet. Module fixation is achieved using a threaded or rotating locking mechanism. This method is typically used in scenarios requiring high installation stability, offering durability but relatively slow installation and removal speeds. Magnets are used as an auxiliary or primary fixing force, allowing the module to automatically adhere to the interface via magnetic force. Magnetic installation and removal are convenient, but the design must ensure sufficient shock resistance and anti-accidental suction functionality.
[0010] The predetermined positions include the helmet ear flaps, the center of the helmet forehead, the right side of the helmet forehead, and the chin area of the helmet.
[0011] A locking device is provided on the outside of the flexible connection hole 11. After the expansion module fixing seat 31 is inserted, the locking device locks the fixing seat to further ensure that it will not fall off and to ensure the stability of the expansion device.
[0012] The working principle of this utility model is as follows: When the expansion module needs to be installed, the expansion module is first fixed or plugged into the expansion module mounting base 31. Then, the expansion module mounting base 31 is inserted into the flexible connection hole 11 on the helmet and pushed in a predetermined direction, so that the anti-slip rib 311 enters the anti-slip groove 111. During the pushing process, the anti-slip rib 311 undergoes elastic deformation upon contact with the anti-slip groove 111. After the anti-slip rib 311 is fully inserted into the anti-slip groove 111, its elastic recovery action firmly locks the anti-slip rib 311 into the anti-slip groove 111, thereby achieving a stable connection between the expansion module mounting base 31 and the helmet.
[0013] The helmet body 1 of this utility model not only provides mechanical fixation, but also has a built-in standardized electrical interface to realize data transmission and power supply for various devices. The built-in microprocessor of the helmet body can automatically identify the type of installed module and configure it accordingly through the communication protocol to ensure that each module functions normally and operates in an integrated manner.
[0014] By adopting the above technical solution, this utility model employs a modular design, enabling rapid assembly and disassembly of various functional modules (such as Bluetooth headsets, cameras, fans, etc.) through independent, standardized flexible interfaces. This greatly improves the product's flexibility and adaptability, allowing users to replace or upgrade individual modules as needed without replacing the entire helmet. Furthermore, the key mechanical snap-fit connection method not only ensures secure and precise installation between modules but also provides anti-misoperation and shock-resistant performance, ensuring the helmet remains stable even during high-speed movement and harsh environments. This reduces maintenance and repair costs while enhancing overall safety and user comfort. Even if a particular expansion module malfunctions, it can be quickly disassembled and replaced via the base, further reducing usage and maintenance costs. Attached Figure Description
