[0039] Example 1

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this embodiment provides a locking mechanism for a helmet, including a driving member 10 and a locking unit 20. The driving member 10 is disposed in the middle of the chin support 1 of the helmet. Two sets of locking units 20 are provided, one locking unit 20 is disposed on one end of the chin support 1, and the other locking unit 20 is disposed on the other end of the chin support 1. The locking unit 20 includes a fixing member 201 disposed on the helmet frame 2, and a locking member 202 that is rotated to lock or unlocked with the fixing member 201. The locking member 202 is swaying on the chin support 1. A linkage rope 203 is provided between the driving member 10 and the locking member 202 to drive the locking member 202 to sway.

[0041] Specifically, one end of the linkage rope 203 is fixed to the drive component 10, and the other end of the linkage rope 203 is connected to the locking component 202. When the drive component 10 is operated, it drives the linkage rope 203 to move synchronously, so that the locking component 202 and the fixing component 201 rotate to lock or separate and unlock, ensuring that the chin frame 1 is tightly locked to the helmet frame 2 through the locking component 202, effectively preventing loosening and improving the stability and safety of wearing.

[0042] In this embodiment, the linkage rope 203 is made of high-strength nylon, which has good wear resistance and tensile strength, ensuring that it will not deform after long-term use. Alternatively, steel wire rope can be used, which has even higher strength and durability. Furthermore, the design of the linkage rope 203 also considers ease of operation. For example, a bicycle brake rope has a return spring at its end, so that after the locking member 202 separates from the fixing member 201, when the driving member 10 is released, the spring force resets and re-engages the locking member 202. The user only needs to pull the driving member 10 to quickly lock or unlock. Alternatively, the locking member 202 can be manually engaged with the fixing member 201 after being separated by the driving member 10, achieving flexibility and convenience during use.

[0043] like Figure 3 and Figure 5As shown, in this embodiment, the locking component 202 is provided with a snap-fit ​​groove 2021 for connecting to the linkage rope 203. The snap-fit ​​groove 2021 facilitates quick fixing, forming a fixed point for the installation of the linkage rope 203, thereby improving production efficiency and stability. The snap-fit ​​groove 2021 is cleverly designed to ensure that the linkage rope 203 is firmly installed, avoiding the risk of falling off, and further enhancing the user experience.

[0044] In this embodiment, the fixing component 201 is a bolt, pin, or barb; the locking component 202 is provided with a hook groove 2022 that engages with the fixing component 201. Thus, by engaging the hook groove 2022 with the bolt, pin, or barb, the effect of rotational engagement or disengagement / unlocking can be achieved, improving operational convenience and safety. The fixing component 201 and the locking component 202 fit tightly, ensuring stable locking, reducing the risk of accidental unlocking, and possessing strong versatility, making it suitable for various helmets.

[0045] like Figure 3 and Figure 4 As shown, in this embodiment, the locking unit 20 is provided with a mounting frame 204 for hinged mounting of the locking component 202. The mounting frame 204 has several mounting holes 2041 for locking with the chin support 1, and a first guide groove 2042 for guiding the direction of the linkage rope 203. The design of the mounting frame 204 allows for pre-assembly or production of the locking component 202 and the mounting frame 204, followed by overall installation through the mounting holes 2041 and threads. This allows for flexible design and assembly. The corresponding design of the mounting frame 204 can adapt to the chin structure of different helmets. Furthermore, the guide groove can be designed on the mounting frame 204 to ensure that the linkage rope 203 does not deviate from its trajectory during movement, enhancing the accuracy of operation.

[0046] like Figure 1 and Figure 6 As shown, this embodiment also includes several guide members 30. The guide members 30 are provided with a second guide groove 301 for the linkage rope 203 to pass through. The guide members 30 are set on the lower jaw frame 1.

[0047] Specifically, the guide 30 is a separate accessory that can be installed on the chin rest 1 of the helmet, allowing the guide linkage rope 203 to pass smoothly through, avoiding tangling or jamming and improving operational smoothness. The guide 30 is made of lightweight materials (e.g., plastic), is easy to install, does not affect the overall weight and comfort, and ensures that users maintain a good experience during long-term use.

[0048] like Figure 2 As shown, in this embodiment, the lower jaw frame 1 is provided with a third guide groove 11 for guiding the linkage rope 203 to pass through. This can guide the linkage rope 203 at the end to follow the path, ensuring that the linkage rope 203 does not deviate from the trajectory during movement and enhancing the accuracy of operation.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, the mounting bracket 204 is provided with a friction strip 2043 that abuts against the surface of the locking member 202 on the swing trajectory of the locking member 202; and a limiting groove 2044 is provided on the swing trajectory of the locking member 202 to cover the free end of the locking member 202.

[0050] Specifically, the friction strip 2043 is designed to abut against the surface of the locking component 202, ensuring a secure engagement between the locking component 202 and the fixing component 201; it also reduces frictional resistance, ensuring smooth operation and extending service life. Furthermore, the limiting groove 2044 covers the other side of the locking component 202, allowing the free end of the locking component 202 to swing within the limiting groove 2044, preventing interference with other parts of the helmet and ensuring smooth movement. This design not only improves the reliability of the locking mechanism but also further optimizes the user experience, enabling smooth operation of the helmet in various usage scenarios.

[0051] like Figure 4 As shown, in this embodiment, the mounting bracket 204 has a pressing portion 2045 that abuts against the surface of the locking member 202 at the locking position of the locking member 202 and the fixing member 201. The design of the pressing portion 2045 can provide additional support after the locking member 202 and the fixing member 201 are engaged, preventing the locking member 202 from loosening or disengaging due to external forces, and further enhancing the stability of the locking.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the driving component 10 includes a slider connected to one end of the linkage rope 203, and a fixing frame for the slider to slide, or a sliding groove 12 for the slider is provided on the jaw frame 1. Through the structural cooperation between the sliding groove 12 and the slider, stops can be designed at both ends of the sliding groove 12, so that the slider moves to one end to lock and to the other end to unlock. Alternatively, it can be a single-operation mode, i.e., there is only one unlocking stop on the sliding groove 12, achieving quick unlocking through a single operation of the slider. Then, after disassembling the jaw structure, manual locking is performed to complete the fixation. Alternatively, there is only one locking stop on the sliding groove 12, achieving quick locking through a single operation of the slider; while unlocking requires disassembling the jaw structure and manually operating the slider to the unlocking stop. This achieves different operation designs to accommodate different user habits and scenario requirements, improving the convenience and safety of helmet use.

Simultaneously, it prevents interference between helmet components, further improving wearing comfort. Furthermore, the locking unit 20 can be unlocked to allow disassembly of the chin area for subsequent maintenance and cleaning.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
