Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and more specifically, to a safety helmet with a lighting function. Background Technology

[0002] In existing safety helmet technologies with lighting functions, the angle adjustment function of the lighting lamps is generally severely inadequate, making it difficult to meet the multi-angle lighting needs in complex working environments. Traditional safety helmet lighting systems mostly adopt fixed or simple adjustable designs, which show obvious limitations in practical applications.

[0003] Fixed lighting designs securely mount the light to the front of the safety helmet, with the illumination direction perfectly aligned with the wearer's head orientation, offering no angular adjustment. When illuminating areas not directly in front, the user must turn their head to change the light direction, increasing neck strain and reducing work efficiency. In confined spaces, at heights, or scenarios requiring simultaneous monitoring of multiple work areas, fixed lighting fails to meet flexible lighting needs, severely impacting work quality and safety.

[0004] Another prominent problem with existing safety helmets with lighting functions is poor internal heat dissipation, which seriously affects user comfort and equipment lifespan, and also increases wearer discomfort. Traditional safety helmet designs focus more on external protection functions and do not adequately consider internal heat management, leading to a series of usage problems. Utility Model Content

[0030] Please see Figures 1-5 A safety helmet with lighting function includes a helmet body 1, a lighting rotation mechanism, a position fixing mechanism, and a fixing auxiliary mechanism. The lighting rotation mechanism includes a mounting frame 2, a rotating frame 3, a lighting component 4, an adjusting plate 5, adjusting holes 6, a locking tube 7, and a locking rod 8. The rotating frame 3 is rotatably connected to the mounting frame 2. The lighting component 4 is mounted on the rotating frame 3. The adjusting plate 5 is mounted on one end of the rotating frame 3. The locking tube 7 is fixedly mounted on the mounting frame 2. Multiple sets of adjusting holes 6 are provided on the adjusting plate 5. The locking rod 8 can extend through the adjusting holes 6 at different positions. The rotating frame 3 is fixed to the mounting frame 2 by extending into the clamping tube 7. The position fixing mechanism includes a guide rotating frame 9, a guide rotating groove 10, a centripetal frame 11, a centripetal groove 12, and an embedded plate 13. The guide rotating frame 9 is limited to rotating and installed in the side wall of the clamping tube 7. The centripetal frame 11 is fixedly installed in the clamping tube 7. The guide rotating groove 10 and the centripetal groove 12 are respectively provided on the guide rotating frame 9 and the centripetal frame 11. The top end and the bottom end of the embedded plate 13 are respectively engaged with the guide rotating groove 10 and the centripetal groove 12 for centripetal sliding connection. The embedded plate 13 can be embedded into or away from the clamping rod 8.

[0031] In this embodiment, the lighting rotation mechanism enables the adjustment and fixation of the lighting component 4's angle. First, the locking rod 8 is removed, and the connection between the locking rod 8 and the locking tube 7 is released. At this time, the connection between the rotating frame 3 and the mounting frame 2 is released, allowing the rotating frame 3 to rotate freely around its connection point with the mounting frame 2, thus changing the illumination angle of the lighting component 4. After adjusting to a suitable angle, the locking rod 8 is reinserted through the different adjustment holes 6 on the adjustment disc 5 and extends into the locking tube 7 to complete the angle locking. The design of multiple sets of adjustment holes 6 provides multi-level angle adjustment options to meet different working conditions. To meet the lighting requirements of the scene, the positioning fixing mechanism achieves a locking connection between the locking rod 8 and the locking tube 7. After the locking rod 8 is inserted into the locking tube 7, the guide frame 9 is rotated. The guide groove 10 on the guide frame 9 drives the embedded plate 13 to move. The top of the embedded plate 13 cooperates with the guide groove 10, and the bottom cooperates with the centripetal groove 12. Under the guidance of the centripetal frame 11, it makes a centripetal movement. As the guide frame 9 rotates, the embedded plate 13 gradually moves inward and finally embeds the locking rod 8, forming a stable locking connection. When unlocking, the guide frame 9 is rotated in the opposite direction, and the embedded plate 13 is removed from the locking rod 8, so the locking rod 8 can be taken out.

[0032] The fixed auxiliary mechanism includes an outer rotating frame 14, a rotating plate 15, a spring rod 16, and a mating hole 17. The outer rotating frame 14 is rotatably mounted on the outer wall of the clamping tube 7. The bottom end of the outer rotating frame 14 is connected to the top end of the guide rotating frame 9. Multiple sets of rotating plates 15 are mounted on the top end of the outer rotating frame 14. Multiple sets of spring rods 16 are mounted on the outer wall of the clamping tube 7. The mating hole 17 is set on the rotating plate 15. The spring rods 16 can extend into the mating hole 17 step by step. The rotating plate 15 and the outer rotating frame 14 rotate stably, so that the guide rotating frame 9 stably drives the embedded plate 13 to move.

[0033] In this embodiment, the outer rotating frame 14 is installed on the outer wall of the clamping tube 7, and its bottom is connected to the guide rotating frame 9. Multiple sets of rotating plates 15 are installed on the top. When the outer rotating frame 14 is rotated, the guide rotating frame 9 is driven to rotate synchronously. The mating holes 17 on the rotating plate 15 are engaged with the spring rods 16 on the outer wall of the clamping tube 7 in stages. When the rotation reaches a certain position, the spring rods 16 spring into the corresponding mating holes 17, producing a clear locking sensation, so that the operator can clearly perceive the rotation progress and prevent improper operation. At the same time, the engagement between the spring rods 16 and the mating holes 17 also provides a rotation positioning function to ensure reliable locking.

[0034] Please see Figures 1-5As a supplementary embodiment of a safety helmet with lighting function, which includes a lighting rotation mechanism, a position fixing mechanism, and a fixing auxiliary mechanism: A mounting platform 18 is installed on the front end of the helmet body 1, and a mounting bracket 2 is fixedly installed on the mounting platform 18. A heat dissipation fan assembly 19 is installed on the back end of the helmet body 1, and a heat absorption pipe 20 is installed on the top end of the helmet body 1. The heat absorption pipe 20 is configured to cooperate with the heat dissipation assembly. A heat dissipation cavity 21 is opened inside the helmet body 1, and one end of the heat absorption pipe 20 extends into the heat dissipation cavity 21. A connecting plate 22 is installed on the bottom end of the side wall of the clamping pipe 7, and the connecting plate 22 is fixedly installed on the inner end face of the mounting bracket 2. A guide block 23 is provided on the embedded plate 13, and the guide block 23 is rotated and slidably connected in the guide groove 10. A chin strap 24 is installed on the bottom end of the helmet body 1.

[0035] More specifically, remove the locking rod 8, disconnect the locking rod 8 from the locking tube 7, rotate the rotating frame 3, adjust the angle of the lighting component 4, select the corresponding adjustment hole 6 on the adjustment plate 5 as needed, reinsert the locking rod 8, after the locking rod 8 is inserted into the locking tube 7, rotate the outer rotating frame 14, the outer rotating frame 14 drives the guide rotating frame 9 to rotate, and through the guide rotating groove 10, the embedded plate 13 moves inward along the centripetal groove 12, embedding the locking rod 8 to form a firm lock. During the rotation, the mating hole 17 on the rotating plate 15 engages with the spring rod 16 step by step, providing segmented operation feedback to ensure that the lock is in place. After the angle adjustment and locking are completed, the lighting component 4 is fixed at the required angle, providing stable lighting for the user. The heat dissipation cavity 21, heat absorption pipe 20 and heat dissipation fan assembly 19 inside the cap body 1 work together to ensure that the equipment does not overheat during long-term use.

[0036] In summary, when the overall equipment is in use or operation: When the lighting rotation mechanism is required to operate, the lighting rotation mechanism realizes the adjustment and fixation of the lighting component 4. First, take out the locking rod 8 and disconnect the locking rod 8 from the locking tube 7. At this time, the connection between the rotating frame 3 and the mounting frame 2 is released, and the rotating frame 3 can rotate freely around its connection point with the mounting frame 2, driving the lighting component 4 to change the illumination angle. After adjusting to the appropriate angle, the locking rod 8 is reinserted and extended into the locking tube 7 through the different adjustment holes 6 on the adjustment plate 5 to complete the angle locking. The design of multiple sets of adjustment holes 6 provides multi-level angle adjustment options to meet the lighting needs of different working scenarios.

[0037] When the position fixing mechanism is in operation, it achieves a locking connection between the locking rod 8 and the locking tube 7. After the locking rod 8 is inserted into the locking tube 7, the guide frame 9 is rotated. The guide groove 10 on the guide frame 9 drives the embedded plate 13 to move. The top of the embedded plate 13 cooperates with the guide groove 10, and the bottom cooperates with the centripetal groove 12. Under the guidance of the centripetal frame 11, it makes a centripetal movement. As the guide frame 9 rotates, the embedded plate 13 gradually moves inward and finally embeds the locking rod 8, forming a stable locking connection. When unlocking, the guide frame 9 is rotated in the opposite direction, and the embedded plate 13 is removed from the locking rod 8, so the locking rod 8 can be taken out.

[0038] When the auxiliary mechanism is required to operate, it provides stable control and segmented feedback for the locking operation. The outer rotating frame 14 is installed on the outer wall of the clamping tube 7, connected to the guide rotating frame 9 at the bottom, and has multiple sets of rotating plates 15 installed at the top. When the outer rotating frame 14 is rotated, it drives the guide rotating frame 9 to rotate synchronously. The mating holes 17 on the rotating plates 15 engage with the spring rods 16 on the outer wall of the clamping tube 7 in stages. When the rotation reaches a certain position, the spring rods 16 spring into the corresponding mating holes 17, producing a clear locking sensation. This design allows the operator to clearly perceive the rotation progress and prevents improper operation. At the same time, the engagement of the spring rods 16 with the mating holes 17 also provides a rotation positioning function, ensuring reliable locking.

[0039] Remove the locking rod 8, disconnect the locking rod 8 from the locking tube 7, rotate the rotating frame 3, adjust the angle of the lighting component 4, select the corresponding adjustment hole 6 on the adjustment plate 5 as needed, reinsert the locking rod 8, after the locking rod 8 is inserted into the locking tube 7, rotate the outer rotating frame 14, the outer rotating frame 14 drives the guide rotating frame 9 to rotate, and through the guide rotating groove 10, the embedded plate 13 moves inward along the centripetal groove 12, embedding the locking rod 8, forming a firm lock. During the rotation, the mating hole 17 on the rotating plate 15 engages with the spring rod 16 step by step, providing segmented operation feedback to ensure that the lock is in place. After the angle adjustment and locking are completed, the lighting component 4 is fixed at the required angle, providing stable lighting for the user. The heat dissipation cavity 21, heat absorption pipe 20 and heat dissipation fan assembly 19 inside the cap body 1 work together to ensure that the equipment does not overheat during long-term use.
