Six spherical triangular component mounting boxes 7 are fixedly installed on the inner wall of the helmet shell 1 and are evenly located above the breathable hood 2. A cushion pad 71 is fixedly installed on the side of the component mounting boxes 7 close to the breathable hood 2. The camera element 3, two communication elements 4, warning light element 5, and two turn signal elements 6 are respectively installed in the six component mounting boxes 7. Each component mounting box 7 contains a battery that separately powers the camera element 3, communication element 4, warning light element 5, and lane change indicator light. The camera end of the camera element 3, the light-emitting ends of the warning light element 5 and the turn signal element 6 respectively pass through the component mounting box 7, and the helmet shell 1 is provided with an opening for the camera end of the camera element 3, the light-emitting ends of the warning light element 5 and the turn signal element 6 to extend out of the interior thereof, and the camera end of the camera element 3 faces the front of the helmet shell 1, the warning light element 5 and the lane change indicator face the rear of the helmet shell 1, and the speaker end and microphone of the communication element 4 are arranged at the bottom of the component mounting box 7, and face the bottom of the helmet shell 1.

[0026] By using the component mounting box 7 containing the camera element 3, communication element 4, warning light element 5, and turn signal element 6, not only can the various components be easily and quickly assembled and fixed inside the helmet shell 1, but each component can also be individually removed through the component mounting box 7, making manual inspection and maintenance of each component very convenient. The cushioning pad 71 on one side of the component mounting box 7 can absorb and disperse the impact force on the helmet shell 1, thereby reducing the risk of head injuries. like Figure 3As shown, an air inlet pipe 11 connecting the inside and outside of the helmet shell 1 is provided at the center of the top of the helmet shell 1, a fan 8 is fixedly installed at the pipe mouth of the air inlet pipe 11, and the blades of the fan 8 are facing directly below the helmet shell 1, a plurality of air inlets 111 are evenly provided on the wall of the air inlet pipe 11, and the air inlet 111 is located above the blades of the fan 8, a cylinder 12 covering the blades of the fan 8 is fixedly provided on the inner wall of the helmet shell 1, and the opening of the cylinder 12 is facing the pipe mouth of the air inlet pipe 11, air outlet holes 121 are evenly provided on the bottom wall of the cylinder 12, and the air outlet holes 121 are facing the top of the breathable hood 2, and six groups of air outlet holes 2 122 are evenly provided on the side wall of the cylinder 12, and the six groups of air outlet holes 2 122 are respectively facing the gaps between the six component mounting boxes 7. By adopting the above-mentioned air inlet pipe 11, fan 8 and cylinder 12, as well as the air inlet 111 on the wall of the air inlet pipe 11 and the air outlet holes 1 and 2 on the cylinder 12, the gap between the component mounting boxes 7 can be utilized to actively ventilate and dissipate heat inside the helmet shell 1 to ensure the wearing comfort of the user. In addition, in conjunction with the sealing pipe cover 9 threadedly connected to the top of the air inlet pipe 11, the air inlet 111 on the wall of the air inlet pipe 11 can be closed in rainy or cold weather conditions, thereby preventing external rain or cold air from entering the interior of the helmet shell 1.

[0027] like Figure 1 、 Figure 3 As shown, the movable cover on the air inlet pipe 11 is provided with a sealing pipe cover 9, and the inner wall of the sealing pipe cover 9 and the outer wall of the air inlet pipe 11 are threadedly connected to each other.

The top of the sealing pipe cover 9 is in the shape of a spherical cap, and the edge of the spherical cap extends outside the water retaining grooves 112. By adopting the above-mentioned sealing pipe cover 9 and water retaining grooves 112, when the user encounters rainy or cold weather, by twisting the sealing pipe cover 9, the air inlet 111 on the wall of the air inlet pipe 11 can be closed, thereby preventing external rainwater or cold air from entering the interior of the helmet shell 1.

The support ring 113 is evenly distributed with multiple threaded holes 113a, each of which is threadedly connected to a fixing screw 113b that passes through the mounting plate 81. The screw connection between the support ring 113 and the mounting plate 81 not only stabilizes the fan 8 but also allows maintenance personnel to easily disassemble and repair the fan 8 at any time.

[0029] like Figure 3 、 Figure 4As shown, six pairs of curved baffles 10 are fixedly installed on the inner wall of the helmet shell 1, and the top ends of the six pairs of curved baffles 10 are fixedly connected to the outer wall of the cylinder 12.

A second fixing screw 721 is inserted into the fixing plate 72, and the second fixing screw 721 passes through the arc-shaped baffle 10 and is threadedly connected to the internal thread of the connecting pipe 101. By adopting the screw fixing structure such as the fixing plate 72, the connecting pipe 101 and the second fixing screw 721, not only can the component mounting box 7 be stably fixed to the inner wall of the helmet shell 1, but it can also be convenient for maintenance personnel to disassemble and assemble the component mounting box 7 at any time to inspect and maintain its internal components. like Figure 4 As shown, six pairs of serial plugs 123 are evenly arranged on the outer wall of the cylinder 12, and the six pairs of serial plugs 123 are respectively located in the gaps of the six pairs of arc baffles. A pair of serial slots 73 respectively connected to and contacting two serial plugs 123 are fixed on the top of the component mounting box 7, and the two serial slots 73 are connected to the positive and negative poles of the battery in the component mounting box 7. The six pairs of serial plugs 123 and the power supply end of the fan 8 are connected through serial wires 124 to form a series circuit. A charging port 74 connected to the above-mentioned series circuit is provided at the bottom of the component mounting box 7. The serial wire 124 is located inside the cylinder 12, and an opening is provided on the side wall of the cylinder 12 for the serial wire 124 to connect to the serial plug 123. By adopting the series circuit of the above-mentioned six pairs of serial plugs 123, serial wires 124 and charging port 74, not only can the batteries in all component installation boxes 7 be charged through one charging port 74, but also part of the power of the batteries in all component installation boxes 7 can be distributed to the fan 8 to ensure long-term operation of the fan 8. At the same time, the fan 8 can also cooperate with the cylinder 12 to quickly cool down the serial wires 124 inside the cylinder 12 to ensure the safe operation of the serial wires 124.

A buckle body 211 protrudes from the opposite side of the two parallel portions of the U-shaped clips 21, and a buckle pit 102a is formed on the side wall of the slot 102 to engage with the buckle body 211. By adopting the above-mentioned snap connection structure of the slots 102 and the U-shaped clips 21, the breathable hood 2 can be quickly disassembled and assembled, making it convenient for the user to clean and replace the breathable hood 2, thereby maintaining the cleanliness and hygiene of the interior of the safety helmet.

All cushioning rubber rings 22 are coaxial and have decreasing radii. The use of these cushioning rubber rings 22 not only creates a ventilation gap between the top of the transparent hood and the bottom of the cylindrical body 12 to ensure smooth airflow from the air outlet 121, but also absorbs and disperses impact forces transmitted by the cylindrical body 12, further reducing the risk of head injuries.
