[0025] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0026] Reference below Figure 1 and Figure 2 An airbag 1 of an airbag according to an embodiment of the present invention is described.

[0027] like Figure 1 As shown, the airbag 1 of the airbag according to the embodiment of the utility model comprises: a first inflatable part 10 and a second inflatable part 20. The first inflatable part 10 is the main part of the airbag 1, which can reduce the impact force. After being inflated, it covers the A-pillar 40 and the bottom of the windshield 50. When the vehicle 3 collides with a pedestrian, it can fully protect the pedestrian's head and reduce the damage to the occupants and pedestrians. When the vehicle 3 rear-ends a truck, it can solve the problem of large deformation of the passenger compartment and high occupant casualty rate. The second inflatable part 20 is a component of the airbag 1, which can reduce the impact force. After being inflated, it covers the A-pillar 40 and the windshield 50, and plays a supplementary role in the protection of the A-pillar 40 and the windshield 50. When the vehicle 3 collides with a pedestrian, it can fully protect the pedestrian's head and reduce the damage to the occupants and pedestrians. When the vehicle 3 rear-ends a truck, it can solve the problem of large deformation of the passenger compartment and high occupant casualty rate.

[0028] like Figure 1 and Figure 2 As shown, after the first inflatable part 10 is inflated, it covers the A-pillar 40 and the lower part of the windshield 50. At this time, the engine hood can be lifted and a gap can be created, and the impact force of the rigid structure around the windshield 50 can be buffered, so that when the vehicle 3 collides with a pedestrian, the pedestrian's head can be fully protected, reducing the damage to the occupants and pedestrians. When the vehicle 3 rear-ends a truck, the problem of large deformation of the passenger compartment and high occupant casualty rate can be solved.

[0029] like Figure 1 and Figure 2As shown, the second inflatable part 20 is connected to the first inflatable part 10 , and the gas in the first inflatable part 10 is selectively passed into the second inflatable part 20 . After the second inflatable part 20 is inflated, it covers the A-pillar 40 and the windshield 50 . The second inflatable part 20 is connected to the first inflatable part 10, and the gas in the first inflatable part 10 is selectively passed into the second inflatable part 20. The second inflatable part 20 is connected to the first inflatable part 10 when it is set. The first inflatable part 10 selectively passes the gas into the second inflatable part 20 according to the internal pressure. When the second inflatable part 20 is not inflated, the second inflatable part 20 acts as a drawstring. When the second inflatable part 20 is inflated, the second inflatable part 20 covers the A-pillar 40 and the windshield 50 after inflation. At this time, the second inflatable part 20 plays a supplementary role in the protection of the A-pillar 40 and the windshield 50. In this way, when the vehicle 3 collides with a pedestrian, the pedestrian's head can be fully protected and the damage to the occupant and the pedestrian can be reduced. When the vehicle 3 rear-ends a truck, the problems of large deformation of the passenger compartment and high occupant casualty rate can be solved.

[0030] Therefore, the airbag 1 includes a first inflatable part 10 and a second inflatable part 20. After the first inflatable part 10 is inflated, it covers the A-pillar 40 and the bottom of the windshield 50, and after the second inflatable part 20 is inflated, it covers the A-pillar 40 and the windshield 50. In this way, when the vehicle 3 collides with the pedestrian, the pedestrian's head can be fully protected to reduce the damage to the occupants and pedestrians. When the vehicle 3 rear-ends a truck, the problem of large deformation of the passenger compartment and high occupant casualty rate can be solved.

[0031] Specifically, Figure 1 As shown, an inflation hole is provided at the connection between the first inflatable part 10 and the second inflatable part 20, and the inflation hole selectively connects the first inflatable part 10 and the second inflatable part 20. The first inflatable part 10 and the second inflatable part 20 are connected through an adaptive inflation hole, and the opening and closing of the inflation hole are controlled according to the pressure inside the first inflatable part 10. When the air hole is closed, the second inflatable part 20 is not inflated, and the second inflatable part 20 acts as a drawstring. When the inflation hole is opened, the second inflatable part starts to inflate, and the second inflatable part 20 covers the A-pillar 40 and the windshield 50 after inflation. At this time, the second inflatable part 20 plays a supplementary role in the protection of the A-pillar 40 and the windshield 50. In this way, when the vehicle 3 collides with a pedestrian, the pedestrian's head can be fully protected and the damage to the occupant and the pedestrian can be reduced. When the vehicle 3 rear-ends a truck, the problem of large deformation of the passenger compartment and high occupant casualty rate can be solved.

[0032] Among them, Figure 1As shown, the first inflatable portion 10 is constructed as a U-shaped structure, the second inflatable portion 20 is constructed as an X-shaped structure, and the second inflatable portion 20 is connected to the inner side of the first inflatable portion 10. The first inflatable portion 10 is constructed as a U-shaped structure, so that when the vehicle 3 collides, the front end surface of the airbag 1 has a certain curvature, which can increase the contact area between the head of the occupant and the pedestrian and the airbag 1, and reduce the pressure per unit area, thereby increasing the protection of the head of the occupant and the pedestrian. The second inflatable portion 20 is constructed as an X-shaped structure, which can provide more comprehensive and effective protection. When the vehicle 3 collides, the second inflatable portion 20 can better adapt to the body shape of the occupant, fully protect the head of the occupant, and reduce the damage to the occupant. The second inflatable portion 20 is connected to the inner side of the first inflatable portion 10, which can better adapt to the body shape of the occupant, provide more comprehensive protection, and reduce the occupant casualty rate.

[0033] In addition, if Figure 1 As shown, the airbag 1 of the airbag further includes: a third inflatable part 30, which is connected to the first inflatable part 10. After the third inflatable part 30 is inflated, it covers the side of the A-pillar 40. The third inflatable part 30 is a component of the airbag 1, which can reduce the impact force and protect the occupants and pedestrians. The third inflatable part 30 is connected to the first inflatable part 10. At this time, the third inflatable part 30 and the first inflatable part 10 are inflated at the same time. The third inflatable part 30 can play a positioning role for the first inflatable part 10. After the third inflatable part 30 is inflated, it covers the side of the A-pillar 40. In this way, when the vehicle 3 is hit from the side, the third inflatable part 30 can play a buffering role and reduce the damage to the personnel.

[0034] Of course, if Figure 1 As shown, the third inflatable portion 30 is constructed as an L-shaped structure, and there are two third inflatable portions 30, and the two third inflatable portions 30 are respectively connected to the two sides of the first inflatable portion 10. The third inflatable portion 30 is constructed as an L-shaped structure, which can better adapt to occupants of different body shapes and ensure that more comprehensive and effective protection can be provided in the event of a collision. Two third inflatable portions 30 are provided, and the two third inflatable portions 30 are respectively connected to the two sides of the first inflatable portion 10, so that the two third inflatable portions 30 can respectively correspond to the sides of the A-pillars 40 on both sides, so that after inflation, the sides of the A-pillars 40 on both sides can be covered. When the vehicle 3 is subjected to a side collision, the third inflatable portion 30 can better play a buffering role and reduce the damage to the personnel.

[0035] Furthermore, if Figure 1As shown, the first inflatable part 10, the second inflatable part 20 and the third inflatable part 30 are all cut-resistant coated woven fabric structures. The cut-resistant coated woven fabric structures have excellent cut-resistant performance and durability. The first inflatable part 10, the second inflatable part 20 and the third inflatable part 30 are all set as cut-resistant coated woven fabric structures, which can prevent the airbag 1 from being cut and can maintain pressure for at least 400ms, thereby more effectively protecting the A-pillar 40, and then protecting the occupants and pedestrians when the vehicle 3 rear-ends a truck or collides with a pedestrian.

[0036] like Figure 1 As shown, the airbag 2 according to the embodiment of the utility model includes: a generator, a guide member 60, the generator is connected with the guide member 60, and the airbag 1 of the airbag described in the above embodiment, the guide member 60 is connected with the first inflatable part 10. The generator can be mainly used to inflate quickly when the vehicle 3 collides to protect the occupants from injury. The generator can adopt a two-stage generator, which is arranged under the hood 70. The guide member 60 can effectively fix the position of the airbag 2 to ensure its normal deployment and function. The design of the guide member 60 can optimize the gas flow and improve the efficiency and protection effect of the airbag 2. The generator is connected to the guide member 60, so that when the vehicle 2 collides with a pedestrian, the first-stage generator is ignited to inflate the first inflatable part 10 and the third inflatable part 30 of the airbag 1. When the vehicle 2 rear-ends a truck, the first-stage generator is ignited first, and the first inflatable part 10 and the third inflatable part 30 are inflated. After they are full, the second-stage generator is ignited. As the pressure of the first inflatable part 10 increases, the inflation hole opens, and the second inflatable part 20 begins to inflate. The guide member 60 is connected to the first inflatable part 10, which facilitates the rapid inflation and deployment of the airbag 2.

[0037] In addition, the airbag 2 also includes: a sensing element, which is used to sense the type of collision target and the collision speed. The sensing element is a component of the airbag 2, which can sense and identify the type of collision target and the collision speed, detect and judge the impact signal when the vehicle 3 collides, so as to timely detonate the airbag 2. Among them, the sensing element can be a sensor.

[0038] It should be noted that the airbag 2 further includes: a controller, and the induction element and the generator are electrically connected to the controller respectively. The controller is a component of the airbag 2, and can be mainly used to protect the safety of passengers and drivers when the vehicle 3 collides, and can solve the problems of large deformation of the passenger compartment and high casualty rate of passengers. The induction element and the generator are electrically connected to the controller respectively, and work together to protect the safety of passengers and pedestrians.

[0039] It should be noted that the sensing component senses the type and speed of the collision target. After receiving the signal, the control system determines whether to detonate the airbag 2, and determines how to detonate the airbag 2 according to the type of the target. When the sensing component senses that the target type is a pedestrian, the airbag 2 generator detonates the first stage, and the airbag 1 inflates the first inflatable part 10 and the third inflatable part 30 to fully protect the pedestrian's head. When the sensing component senses that the collision target is a truck, the airbag 2 generator detonates the first and second stages, and the inflation hole of the airbag 1 opens to complete the inflation of the first inflatable part 10, the second inflatable part 20 and the third inflatable part 30 to protect the A-pillar 40 of the vehicle 3, thereby achieving the purpose of protecting the passenger compartment and the occupants. When the sensing component senses that the collision target is the vehicle 3, the airbag 2 is not detonated, and the occupants are protected by relying on the stiffness of the vehicle 3 body and the stiffness of the restraint system.

[0040] like Figure 2 As shown, the vehicle 3 according to the embodiment of the utility model comprises: a hood 70 and the airbag 2 described in the above embodiment, and the airbag 2 is arranged at the rear side below the hood 70. The hood 70 can mainly prevent dust, protect other components, and enhance the overall rigidity. The airbag 2 is arranged at the rear side below the hood 70, so that the airbag 2 can better protect the safety of the rear passengers.
