[0038] Example

[0039] like Figure 1 As shown, the embodiment of the present invention provides a safety helmet with a magnetic detachable function, comprising:

[0040] The helmet body 1 is a bowl-shaped structure used to cover the top of the head and protect the head; it is made of a tough material, such as plastic, metal or composite material, to form a bowl-shaped structure to cover and protect the user's head. The helmet body 1 can provide comprehensive protection for the head, including the top, sides and back; the magnetic component includes a first magnetic part 2, which is connected to the outside of the helmet body 1 and is arranged in an arc-shaped fit along the opening edge of the bowl-shaped structure; ensuring that the cover magnetic part of the protective cover 3 can be accurately docked, and the magnetism of the first magnetic part 2 is sufficient to ensure that the protective cover 3 is stably adsorbed on the helmet body 1 under various conditions of use; the protective cover 3 is provided with a cover magnetic part that is magnetically matched with the first magnetic part 2, and the cover magnetic part and the first magnetic part 2 are used together to detachably connect the protective cover 3 to the helmet body 1. It should be noted that the protective cover 3 here can be a magnetic sunshade extension, an electrical insulation protective cover 3, a cold-proof protective cover 3, a high-temperature resistant protective cover 3, etc., which is not limited here and can be installed according to actual needs.

[0041] In an embodiment of the present utility model, a cover magnet part is provided on the protective cover 3, which cooperates with the first magnet part 2 through magnetic adsorption to achieve quick disassembly and installation. Specifically, the connection between the first magnet part 2 and the cover magnet part is achieved by magnetic force. The setting of the cover magnet part enables it to be tightly adsorbed with the first magnet part 2, ensuring that the protective cover 3 is stably fixed on the helmet body 1. This connection method avoids the tedious installation and disassembly that may be caused by traditional screws or buckles, and reduces the risk of damage caused by mechanical connection. The magnetic connection allows users to quickly disassemble and install the protective cover 3, which improves work efficiency. The stable connection ensures that the protective cover 3 will not fall off accidentally during use, enhancing the protective function of the helmet. Due to the simplification of the connection method, unnecessary pressure points on the head are reduced, and wearing comfort is improved. The magnetic setting allows the helmet to quickly replace protective covers 3 with different functions according to the specific working environment, improving the adaptability and versatility of the helmet.

[0042] As a preferred embodiment of the present invention, the arc angle of the first magnetic member 2 is greater than 60 degrees. A larger arc angle can provide a wider contact area and stronger magnetic adsorption ability because the magnetic member is in closer contact with the protective cover 3, thereby improving the stability and adsorption force of the connection.

[0043] Furthermore, a number of limiting grooves 4 are provided on the outside of the cover magnet part, and a number of limiting protrusions are provided on the cover magnet part; a single limiting protrusion can be inserted into a single limiting groove 4, ensuring the precise fit and fixation between the protective cover 3 and the helmet body 1. Specifically, a single limiting protrusion can be inserted into a single limiting groove 4, and this fitting relationship is called a "stop" structure, which is used to limit the relative movement between the protective cover 3 and the helmet body 1 on the X-axis and Y-axis. In an embodiment of the present utility model, this limiting structure can improve the stability of the connection between the protective cover 3 and the helmet body 1, reduce the risk of accidental falling off during operation, and also facilitate the user to quickly disassemble and install the protective cover 3 as needed. Through this structural setting, the practicality and safety of the helmet are significantly improved. It should be noted that the shape structure of the limiting groove 4 and the limiting protrusion is not limited here, as long as the purpose of sufficient limiting stability can be achieved. As a preferred embodiment of the present invention, a single limiting groove 4 is cross-shaped, and a single limiting protrusion is cross-shaped. The limiting groove 4 and the limiting protrusion are adapted to fit together. This structure enables the single limiting protrusion to accurately insert into the corresponding limiting groove 4, providing a stable and precise fit. This cross-shaped structure not only ensures proper alignment between the protective cover 3 and the helmet body 1, but also provides a limiting effect in multiple directions, thereby enhancing the stability of the connection. This ensures that the protective cover 3 will not easily fall off in the event of an impact or accidental collision, and also facilitates the user's quick removal of the protective cover 3 for replacement or cleaning when necessary.

[0044] For example, Figure 4 As shown, the arc angle of the first magnetic part 2 is 180 degrees, and there are three limiting grooves 4, which are respectively arranged at the two ends and the middle of the first magnetic part 2. There are three limiting protrusions, and a single limiting protrusion is arranged corresponding to a single limiting groove 4. Specifically, the arc angle allows the magnetic part to extend along the entire forehead area of ​​the bowl-shaped structure of the helmet, providing a wide contact surface and a strong magnetic adsorption force. Such a design can ensure a close fit between the protective cover 3 and the helmet body 1. At the same time, the 180-degree arc also helps to disperse the force, reduce local pressure points, and improve wearing comfort. Three limiting grooves 4 are provided on the first magnetic part 2, respectively located at both ends and in the middle. This distribution method can provide uniform fixing points along the entire length of the magnetic part, ensuring that the protective cover 3 can be stably fixed on the helmet body 1 in different areas. The limiting protrusions correspond to the limiting grooves 4. Three limiting protrusions are provided, and each limiting protrusion matches a limiting groove 4. This one-to-one matching relationship can ensure that the protective cover 3 is accurately aligned during installation to avoid misalignment or offset. In an embodiment of the present utility model, multiple fixing points provide better stability, reducing the risk of shaking or falling off of the protective cover 3 during use. The evenly distributed limiting structure helps to disperse force when impacted and protect the user's head. The precise matching design makes the installation and removal of the protective cover 3 simple and quick, and convenient for user operation.

[0045] In order to realize the lighting function of the embodiment of the utility model, Figure 2 As shown, the magnetic component of the embodiment of the utility model also includes a second magnet 5, which is arranged on the outside of the helmet body 1 and is used for magnetic connection with the magnetic light 6. The second magnet 5 can rotate around its center. Specifically, the second magnet 5 is arranged on the outside of the helmet body 1 and is specifically used for magnetic connection with the magnetic light 6, so that the user can quickly install and remove the light as needed, thereby improving the convenience and safety of working in low-light environments. The second magnet 5 can rotate around its center, and the user can adjust the angle and direction of the light according to lighting needs. Preferably, as Figure 5 As shown, a mounting groove 7 for mounting a second magnetic part 5 is provided on the outside of the helmet body 1. The second magnetic part 5 is installed in the mounting groove 7 through a rotating rod. A flexible rubber mechanism 8 is provided between the second magnetic part 5 and the inner wall of the mounting groove 7. The flexible rubber mechanism 8 is used to limit the second magnetic part 5 after the rotation angle is adjusted.

[0046] Specifically, to ensure the stability of the second magnetic member 5, a mounting groove 7 is used to mount the second magnetic member 5, while a flexible rubber mechanism 8 is used to limit the second magnetic member 5 after it is rotated to adjust the angle. This ensures that the magnetic member will not easily slide or shift after being adjusted to the ideal position, ensuring stability during use. The mounting groove 7 is used to secure the second magnetic member 5, ensuring that the second magnetic member 5 can be stably mounted on the helmet and provides a suitable position so that the magnetic light 6 can be easily aligned and connected to the second magnetic member 5. The second magnetic member 5 is mounted in the mounting groove 7 via a rotating rod, allowing the magnetic member to rotate within a certain angle range, allowing users to adjust the direction of the light according to their needs to achieve the optimal lighting effect. The flexible rubber mechanism 8 provides a limiting effect after the second magnetic member 5 is rotated to a specific angle, preventing the magnetic member from sliding or shifting during use. The elasticity and flexibility of the flexible rubber mechanism 8 enable it to adapt to multiple adjustments and rotations while ensuring the stability of the second magnetic member 5. Therefore, through the use of the limiting mechanism, the lighting lamp can be maintained in the set position even in a dynamic working environment to provide stable lighting. The user can easily adjust the direction of the lighting lamp according to the specific working environment and personal preferences without the need for disassembly or reinstallation. The setting of the flexible rubber mechanism 8 can also reduce the direct friction between the magnet and the mounting groove 7, thereby extending the service life of the magnet and the entire safety helmet.

[0047] Furthermore, a calling device and a calling switch 9 are provided on the top of the helmet body 1. The calling switch 9 is used to control the opening or closing of the calling device, and the calling device is used to send a distress signal. Specifically, the calling device is an existing device, which generally includes a small radio transmitter or other signal sending device. When the operator encounters an emergency, a distress signal can be sent through this device. The signal can be a sound, light or radio signal so that people around or rescue teams can quickly locate and provide help. The calling switch 9 allows the user to control the activation of the calling device. The calling switch 9 can be set as a button, a sliding switch or a touch-sensitive switch, which is convenient for the user to operate quickly when needed. It can also include long press or continuous press to prevent misoperation. Integrating the calling device and the switch in the helmet ensures that the operator can easily access these functions at any time without the need to carry other equipment. As a preferred embodiment of the present invention, such as Figure 3 As shown, a mobile battery 11 for powering the calling device is provided inside the helmet body 1 .

[0048] Illustratively, in an embodiment of the present invention, the calling device includes a speaker hole 10 connected to the air, a filter is provided on the inside of the speaker hole 10, and the speaker hole 10 is designed to be connected to the air to ensure that sound can be transmitted in and out. A filter is provided on the inside of the speaker hole 10 to prevent dust, debris or other contaminants from entering the speaker hole 10, thereby protecting the internal components of the calling device from damage and ensuring the clarity of sound transmission. This structure not only improves the safety of workers in dangerous environments, but also enhances the communication capabilities between teams. The presence of the filter ensures that the calling device can maintain its functionality even in harsh working environments, reducing maintenance requirements and potential failure risks.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention. It should be noted that the structures and components illustrated in the accompanying drawings are not necessarily drawn to scale, and that descriptions of known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the present invention.
