[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] Please refer to the attached Figures 1 to 6 , the airbag safety helmet according to the embodiment of the present invention is described in detail.

[0031] The airbag helmet of the embodiment of the present invention comprises an inner shell 2, an outer shell 1 and an airbag assembly 3. The inner shell 2 is provided with straps 4 at both ends in a preset direction, the outer shell 1 is provided on the inner shell 2, and a mounting cavity 8 is formed between the inner shell 2 and the outer shell 1. The airbag assembly 3 is provided in the mounting cavity 8, and the airbag assembly 3 comprises a controller (not shown in the figure), an airbag body, a pressure sensor 32 and a gas generator (not shown in the figure). The airbag body has a plurality of airbag bodies, and the plurality of airbag bodies are spaced apart, and the airbag body abuts the inner shell 2 and the outer shell 1. In other words, there is gas in the airbag body, so that the surface of the airbag body bulges and abuts the inner shell 2 and the outer shell 1. A gas generator is provided in the airbag body, and a pressure sensor 32 is provided between the airbag body and the inner shell 2. The pressure sensor 32 is connected to the controller to transmit the pressure signal of the airbag body to the controller, and the gas generator is connected to the controller so that the controller controls the gas generator.

[0032] In the airbag helmet of the embodiment of the present invention, under normal conditions, there is gas in the airbag body, the airbag body is in a semi-saturated state, and the airbag body can withstand a certain pressure. When the airbag helmet of the embodiment of the present invention is worn, the preset direction is the left-right direction, such as Figure 1As shown. When the helmet is hit by an external impact, the outer shell 1 is deformed and the impact is transmitted to the airbag body. The pressure sensor 32 can detect the pressure on the airbag body and transmit the pressure signal to the controller. The controller compares the pressure signal with the set value. When the pressure detection value is less than the set value, the controller does not send a signal, that is, the gas generator does not work, and the airbag body in a semi-saturated state can play a role of buffer protection; when the pressure detection value is greater than or equal to the set value, the controller controls all gas generators to work, so that all airbag bodies expand, thereby improving the impact resistance of the impact point of the helmet. If the wearer of the helmet falls down after the first impact, rolls over after falling down, etc., because all airbag bodies of the airbag assembly 3 have expanded, the helmet can resist the impact again in time, avoiding the wearer from secondary injuries caused by the impact.

[0033] The airbag safety helmet 100 of the embodiment of the present invention adopts a double-layer protection formed by an outer shell 1 and an inner shell 2, and an airbag assembly 3 is embedded between the outer shell 1 and the inner shell 2 for protection. While the safety helmet formed by the inner shell 2, the outer shell 1 and the semi-saturated airbag body realizes the reduction of impact force, the rapid inflation of the airbag body can be used for buffering protection. In addition, the airbag body of the embodiment of the present invention has multiple, distributed in different regions, which can enable the safety helmet to achieve synchronous response of airbags in various regions when impacted, so that they can cooperate with each other to improve the protection function when a large impact occurs, ensure the use performance and protection effect of the safety helmet 100, and according to the size of the impact (impact) characteristics of the safety helmet 100, all airbag bodies of the safety helmet can be started at the same time, which will not affect the protection against possible subsequent impacts. The setting of multiple airbag bodies can improve the response speed, improve the expansion speed of the airbag body, and realize efficient anti-collision protection function while ensuring that protection is in place, effectively reduce the impact force of the safety helmet on the head when impacted, and improve the use performance and protection effect of the safety helmet.

[0034] Specifically, the outer shell 1 and the inner shell 2 are both hemispherical shells.

[0035] The edge of the outer shell 1 is provided with a brim 12, and the edge of the inner shell 2 is provided with a peripheral edge 23, which is fixedly connected to the brim 12, and the peripheral edge 23 and the side of the brim 12 facing the mounting cavity 8 form a mounting groove 5. In other words, the edge of the peripheral edge 23 is fixedly connected to the brim 12, and the mounting groove 5 is formed between the inner side of the peripheral edge 23 and the brim 12, and the mounting groove 5 is communicated with the mounting cavity 8.

[0036] In some embodiments, a first reinforcing rib 21 and a second reinforcing rib 22 are provided on the outer side of the inner shell 2. The first reinforcing rib 21 divides the outer side of the inner shell 2 into two parts. Figure 3 and Figure 4As shown, the first reinforcing rib 21 divides the outer side surface of the inner shell 2 into two parts, the left and the right. One end of the second reinforcing rib 22 is vertically connected to the first reinforcing rib 21 at the top of the inner shell 2, and the other end of the second reinforcing rib 22 extends toward the direction of the strap 4. The airbag body is arranged in the area formed between the first reinforcing rib 21 and the second reinforcing rib 22; the inner side surface of the outer shell 1 is provided with a limiting rib 11, and the limiting rib 11 is distributed on both sides of the first reinforcing rib 21 in the thickness direction.

[0037] The first reinforcing rib 21 and the second reinforcing rib 22 are connected in a cross shape and arranged on the inner shell 2, which can not only increase the strength of the inner shell 2 and increase the impact resistance of the inner shell 2, but also can partition and space the outer side of the inner shell 2, so that multiple airbag bodies are physically separated (the first reinforcing rib 21 and the second reinforcing rib 22), ensuring that the multiple airbag bodies do not affect each other, thereby ensuring the stability of the airbag body under normal conditions and ensuring the impact resistance of the airbag body under normal conditions. In addition, the cooperation of the limiting rib 11 and the first reinforcing rib 21 set on the outer shell 1 enables the outer shell 1 to form a limit on the outer shell 1 when deformation occurs, ensuring that it is plastically deformed within a reasonable range. When the helmet is hit in the left and right directions, the outer shell 1 can maintain stability due to the limitation of the limiting rib 11 and the first reinforcing rib 21. The spherical surface of the outer shell 1 can cause the impact object to deviate from the surface of the outer shell 1. When the helmet 100 is hit by an object directly above, the first reinforcing rib 21 and the second reinforcing rib 22 can play a certain buffering role for the downward deformation of the outer shell 1. Therefore, the limiting rib 11 and the first reinforcing rib 21 can increase the integrity between the outer shell 1 and the inner shell 2, and improve the overall performance and protective effect of the safety helmet 100.

[0038] In some embodiments, the other end of the second reinforcing rib 22 is spaced apart from the edge of the inner shell 2, four of the plurality of airbag bodies are first airbag bodies 31a, two of the plurality of airbag bodies are second airbag bodies 31b, the first airbag body 31a is located between the first reinforcing rib 21 and the second reinforcing rib 22, the second airbag body 31b is located between the other end of the second reinforcing rib 22 and the edge of the inner shell 2, and the second airbag body 31b is spaced apart from the adjacent first airbag body 31a. Figure 3 and Figure 4As shown, the six airbag bodies are distributed in a symmetrical form and can wrap the spherical surface of the inner shell 2. The setting of the second airbag body 31b, on the one hand, reduces the volume of the first airbag body 31a, which is beneficial to improving the timeliness of the inflation of the first airbag body 31a and improving the reaction speed of the first airbag body 31a to the impact. On the other hand, the second airbag body 31b is arranged on the left and right sides of the helmet, which can improve the ability of the left and right sides of the helmet to withstand frontal impact and the expansion reaction speed, thereby improving the performance of the helmet 100 in resisting impact and improving the protective effect of the helmet.

[0039] In this embodiment, the four first airbag bodies 31a and the two second airbag bodies 31b of the six airbag bodies all have one side adjacent to the surrounding edge 23 of the inner shell 2, and the pressure sensor 32 corresponding to each airbag body is adjacent to the edge of the inner shell 2. The side of the pressure sensor 32 adjacent to the edge of the inner shell 2 is provided with an interface 321, and the interface 321 is connected to the controller through a wire 36, and at least a part of the wire 36 is arranged in the installation groove 5. There is a certain space in the installation groove 5, and the installation groove 5 is circumferentially connected, which is conducive to the arrangement of the wire 36, and also convenient for the assembly of the six airbag bodies on the inner shell 2, so as to realize the mutual coordination between the multiple airbag bodies.

[0040] In some embodiments, the outer shell 1 is provided with side shells 13 on both sides in a preset direction, that is, the left and right sides of the outer shell 1 are provided with side shells 13. The airbag safety helmet further includes a stabilizing block 6, which connects the side shell 13 and the outer shell 1, and the second airbag body 31b is located on the inner side of the side shell 13. The safety helmet of the embodiment of the present invention can improve the stability of the edge of the outer shell 1 by providing the stabilizing block 6, and can also ensure the structural performance of the outer shell 1 of the safety helmet, so that when foreign objects hit the side shell 13, it can play a good protective performance, thereby improving the impact resistance and protective effect of the safety helmet 100.

[0041] In some embodiments, the inner shell 2 is provided with a pressure-resistant plate 24, which is located on the inner side of the second airbag body 31b. Specifically, the pressure-resistant plate 24 is a hard plastic with a hemispherical shell structure. When a collision occurs, the pressure-resistant plate 24 can play a protective role, and the deformation of the pressure-resistant plate 24 can disperse the force, so as to improve the protective performance of the helmet 100.

[0042] In some embodiments, a first gap 25 is formed between the first reinforcing rib 21 and the adjacent first airbag body 31a, the limiting rib 11 is located in the first gap 25, and a first filling block is provided in the first gap 25; a second gap 26 is formed between the second reinforcing rib 22 and the adjacent first airbag body 31a, and a second filling block is provided in the second gap 26. The material of the first filling block and the second filling block are both hard foam. The hard foam has the function of buffering and absorbing energy, and can improve the impact resistance and protective effect of the helmet 100.

[0043] In some embodiments, the airbag assembly 3 further includes a cushion 33, one side of the cushion 33 is fitted and connected to the airbag body, and the other side of the cushion 33 is connected to the inner shell 2. The cushion 33 is provided with a groove, and the pressure sensor 32 is provided in the groove. When the helmet 100 is hit, the impact point of the outer shell 1 is deformed, and the impacted airbag body is deformed, which then squeezes the cushion 33. After the outer shell 1 and the airbag body absorb energy and reduce vibration, the cushion 33 further absorbs energy and reduces vibration, thereby improving the buffering protection effect of the helmet 100.

[0044] When the impact force on the helmet is too great, the outer shell 1 is deformed and squeezes the first airbag body 31a and / or the second airbag body 31b of the airbag body, and the cushion 33 is squeezed and deformed. After the pressure sensor 32 detects that the pressure value is greater than the preset value, the controller controls the gas generator to start and each airbag body expands.

[0045] The airbag assembly 3 further includes a first adhesive strip 34 and a second adhesive strip 35, wherein the first adhesive strip 34 connects the pressure sensor 32 and the inner housing 2, and the second adhesive strip 35 connects the airbag body and the inner housing 2. The pressure sensor 32 and the airbag body are connected to the inner housing 2 via the first adhesive strip 34 and the second adhesive strip 35, respectively, and the connection method is simple and easy to assemble and fix.

[0046] In some embodiments, a third reinforcing rib 14 is provided on the outer side of the outer shell 1, and the third reinforcing rib 14 is perpendicular to the preset direction. In other words, the third reinforcing rib 14 is arranged in the same direction as the limiting rib 11 and the first reinforcing rib 21, which is the front-to-back direction. The third limiting rib 11 can improve the overall performance of the outer shell 1.

[0047] Furthermore, the helmet includes an inner lining member 7, which includes an inner lining strip 71 and a rubber strip 72. The rubber strip 72 is arranged on the inner side of the edge of the inner shell 2. The inner lining strips 71 are arranged in a cross pattern. The inner lining strips 71 are connected to the rubber strips 72, and the inner lining strips 71 are spaced apart from the inner shell 2. A gap for air circulation is formed between the inner lining strip 71 and the inner surface of the inner shell 2. The helmet 100 directly contacts the wearer's head through the inner lining strip 71. The gap between the inner lining strip 71 and the inner shell 2 can improve the heat dissipation effect, and at the same time provide a buffer space for deformation and movement when the helmet 100 is hit, thereby further improving the impact resistance and protective effect of the helmet 100.
