[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides a safety helmet with a protective liner, such as Figure 1-9 As shown, the helmet includes a main body 1, a front brim 2, and a protective liner 3. The front brim 2 is inserted into the front of the main body 1. The protective liner 3 is detachably connected inside the main body 1. The protective liner 3 includes a headband 31 and a protective part 32. The protective part 32 is detachably connected to the headband 31. The protective part 32 has a star-shaped frame structure. Support blocks 5 with a honeycomb structure composed of hexagonal column-shaped block pads 4 are provided on the front, back, left and right sides of the protective part 32. The support blocks 5 on the left and right sides of the protective part 32 are connected to the frame structure of the protective part 32 through Z-shaped handles 6. The surface of the Z-shaped handles 6 is provided with reinforcing ribs 7.

[0031] The safety helmet consists of three main parts: the helmet shell body 1, the front brim 2, and the protective liner 3. The core protective liner 3 is further divided into two key parts: the headband 31 and the protective section 32, as shown below. Figure 4The shown protective part 32 has a "rice" - shaped skeleton, which is composed of multiple beam frames criss - crossing each other, forming a stable and strong support framework. The "rice" - shaped structure is an extremely efficient mechanical structure that can quickly disperse and conduct the impact force from any direction to multiple directions around, avoiding stress concentration, greatly reducing the harm of point - like impact to the head. And on the premise of ensuring sufficient structural strength, this frame design can be achieved with less material, thus reducing the overall weight of the inner lining and improving the wearing comfort. In addition, the honeycomb - structured support blocks 5 are located at the four key positions of the front, back, left, and right of the "rice" - shaped frame, which are the areas where the head is most likely to be impacted. Each support block 5 is composed of multiple hexagonal - column - shaped block liners 4, and can also be composed of other polygon - shaped, circular - shaped, triangular - shaped column bodies, etc. The honeycomb structure is one of the recognized optimal energy - absorbing structures in nature and engineering. When being impacted, the hexagonal cells will effectively absorb and dissipate huge impact energy through their own elastic deformation, crushing, or even breaking, thereby protecting the head.

[0032] According to an embodiment of the present utility model, as Figure 2 、 8 shown, four symmetrically - distributed connecting pieces 33 are provided on the headband 31. A plurality of through - grooves 34 are formed on the connecting pieces 33. A disc snap 35 is slidably connected in the grooves 34. The disc snap 35 can slide in the grooves 34 and can be fixed at both ends and the middle of the grooves 34. Circular holes 36 for connecting with the disc snap 35 are formed on the frame structure of the protective part 32.

[0033] There are 4 connecting pieces 33, which are symmetrically distributed on the front and back sides of the head, ensuring the balance and stability of the connection between the protective part 32 and the headband 31. As the connection between the two, they carry the grooves 34 and the disc snap 35. The groove 34 is a through - long - strip - shaped opening on the connecting piece 33, whose length determines the adjustment range, provides a sliding track for the disc snap 35, and is also a vertical - direction connection channel. The disc snap 35 is used to engage with the circular hole 36 on the protective part 32 and can be fixed at a specific position in the groove 34. When the protective part 32 needs to be installed on the headband 31, the user only needs to align the circular hole 36 on the frame of the protective part 32 with the disc snap 35 that has been fixed on the connecting piece 33 of the headband 31, and then press it vertically downward.

[0034] According to an embodiment of the present utility model, as Figure 7 shown, a bending plate 21 extending towards the top of the cap shell main body 1 is provided in the middle of the front brim 2. There is a gap between the middle of the front brim 2 and the front part of the cap shell main body 1. Ribs 22 are provided at equal intervals at the connection between the bending plate 21 and the front brim 2. The ribs 22 divide the gap between the middle of the front brim 2 and the front part of the cap shell main body 1 into equally - spaced air ducts. Ventilation holes 23 are provided on the front side and the rear side of the top of the cap shell main body 1. A plurality of through - openings 24 are formed on the surface of the bending plate 21.

[0035] The curved plate 21 is located in the middle of the front brim 2 and extends upwards, eventually contacting the top of the main body 1 of the cap. Its curved shape is the physical basis for forming an efficient ventilation channel. As the curved plate 21 extends upwards, a cavity gap is naturally formed between the middle of the front brim 2 and the front of the main body 1 of the cap. This cavity gap is the main channel for airflow. The rib 22 divides the cavity gap into several independent, equidistant parallel air channels, ensuring that the airflow can be guided in an orderly manner to form streamlines, maximize ventilation efficiency, and avoid generating turbulence or howling noise. On the other hand, it can also divert rainwater or spray water in rainy weather operations or spray environments to the front brim 2 for discharge, thereby preventing the head from getting wet.

[0036] According to one embodiment of the present invention, the inner edge of the cap body 1 is provided with two opposing first connecting claws 11 with grooves, and the outer edge of the front brim 2 is provided with a plug plate 201. The plug plate 201 is inserted between the two opposing first connecting claws 11 so that the front brim 2 is connected to the cap body 1.

[0037] The grooved first connecting claw 11 serves as the female connecting end fixed to the cap shell. The groove structure is used to accommodate and lock the insert plate 201 from the front brim 2. The insert plate 20 serves as the male connecting end of the front brim 2. Its shape allows it to be precisely inserted into the gap between the two opposing first connecting claws 11. During installation, simply align the insert plate 201 of the front brim 2 with the gap between the two first connecting claws 11 and push it in horizontally. The first connecting claw 11 has a certain degree of elasticity. When the insert plate 201 is inserted, its groove will form an interference fit or a snap fit with the structure of the insert plate 201, thereby generating a certain friction or locking force to achieve initial fixation. This insertion method is very convenient and enables the rapid installation and removal of the front brim 2.

[0038] According to one embodiment of the present invention, the plug plate 201 has opposite grooved second connecting claws 2011 at both ends, and the protective part 32 has a cross-shaped frame structure at the end with a plug block 321. The plug block 321 has non-through connecting grooves 322 on both sides, and the connecting grooves 322 on both sides of the plug block 321 are respectively inserted into the grooves of the second connecting claws 2011.

[0039] The second connecting claw 2011 is located at both ends of the plug plate 201 and is also arranged opposite to each other. As the female connecting end of the connecting protective liner, its groove is used to clamp the plug block 321 on the protective part 32. The plug block 321 is the male connecting end, and the connecting grooves 322 on both sides of it are blind grooves, providing a clear termination point and limit point for the connection.

[0040] According to one embodiment of the present invention, the plug plate 201 and the first connecting claw 11 are further fixed by a fastening buckle 8. The fastening buckle 8 is rectangular and has clearance grooves 81 on both sides. An outward limiting protrusion 82 is provided at the bottom of the fastening buckle 8. A stop claw 2012 is provided at the bottom of the second connecting claw 2011. The stop claw 2012 is engaged with the inner side of the limiting protrusion 82.

[0041] Provide ultimate mechanical locking for the above connections, such as Figure 7 , 9 As shown, the fastening buckle 8 is an independent component with clearance grooves 81 on both sides to precisely avoid the first connecting claw 11 and the second connecting claw 2011. The limiting protrusion 82 is located at its bottom and protrudes outward, cooperating with the stop claw 2012 to achieve locking. After the brim 2 and the protective liner 3 are installed in place, the fastening buckle 8 is pushed upward from below into the space at the bottom of the plug plate 201, so that the limiting protrusion 82 moves to the inside of the stop claw 2012 at the bottom of the second connecting claw 2011. Then, the fastening buckle 8 is pushed further so that the clearance groove 81 covers the first connecting claw 11 and the second connecting claw 2011. The fastening buckle 8 itself fills the gap between the plug plate 201 and the first connecting claw 11, effectively preventing the plug plate 201 from accidentally coming loose from the first connecting claw 11, and finally preventing the entire brim 2 and the protective liner 3 from detaching from the helmet body 1.

[0042] According to one embodiment of the present invention, the front brim 2 and the main body of the cap shell 1 are provided with mutually interlocking steps at the two side edges of the connection point.

[0043] According to one embodiment of the present invention, the front brim 2 is made of transparent material.

[0044] According to one embodiment of the present invention, the main body 1 of the cap shell is made of synthetic resin material.

[0045] The overall working principle is as follows:

[0046] The wearer first adjusts and secures the headband 31 according to their head circumference. Then, the protective part 32 is aligned and pressed to connect with the connecting piece 33 on the headband 31 via the disc buckle 35, completing the assembly of the protective liner 3. The insert plate 201 of the front brim 2 is inserted into the first connecting claw 11 inside the main body of the cap shell 1 to achieve initial fixation of the front brim 2. Next, the fastening buckle 8 is pushed in from below and rotated to lock. Through the cooperation of the limiting protrusion 82 and the stop claw 2012, a stable connection is achieved between the front brim 2 and the main body of the cap shell 1. The entire liner is placed inside the main body of the cap shell 1. The insert block 321 at the end of the protective part 32 is pushed into the second connecting claw 2011 on both sides of the front brim 2, so that the connecting groove 322 engages with the groove.

[0047] Upon impact, the protective section 32 with its star-shaped frame structure disperses the impact force in all directions. The honeycomb-shaped support blocks 5 absorb energy through the crushing deformation of the hexagonal pads, while the Z-shaped handle 6 and reinforcing ribs 7 enhance overall impact resistance and stability. Simultaneously, the curved plate 21 of the brim 2 and the ribs 22 form air ducts, working in conjunction with the vents 23 at the top of the helmet to achieve airflow, improve heat dissipation, and ensure the wearer's head remains ventilated and dry. Through the coordinated action of multiple components, this helmet significantly improves protection, comfort, and convenience.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
