Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Hereinafter, with reference to the accompanying drawings, an airbag assembly 100 according to an embodiment of the present invention will be described.

[0030] like Figures 1-8 As shown, the airbag assembly 100 according to an embodiment of the present invention includes: an airbag 1 and a control assembly 2. The airbag 1 includes an airbag body 11 and a deformable portion 12. The airbag 1 has a first deployment state and a second deployment state. In the first deployment state, the deformable portion 12 protrudes from the airbag body 11. In the second deployment state, the deformable portion 12 is housed within the airbag body 11. The control assembly 2 is connected to the deformable portion 12 to control the airbag 1 to deploy to the first deployment state or the second deployment state through the deformable portion 12.

[0031] For example, refer to Figures 1-3 As shown, the airbag assembly 100 can be applied to a vehicle 1000. The airbag assembly 100 includes an airbag 1 and a control assembly 2. The airbag 1 includes an airbag body 11 and a deformable part 12. The airbag 1 has a compressed state and a deployed state. When the vehicle 1000 is involved in a collision, the airbag 1 inflates to deploy from the compressed state to the deployed state. The deployed airbag 1 can be used to cushion the passenger, thereby reducing the passenger's injury.

[0032] The airbag 1 can be deployed in two states: a first deployment state and a second deployment state. In the first deployment state, the deformable portion 12 protrudes from the airbag body 11, and the overall size of the airbag 1 is larger, allowing it to cover a wider area. In the second deployment state, the deformable portion 12 is retracted into the airbag body 11, and the overall size of the airbag 1 is smaller, allowing it to avoid other components (such as the steering wheel 300 described below) and prevent unnecessary damage. The control assembly 2 can be connected to the deformable portion 12 to control the airbag 1 to deploy to either the first or second deployment state.

[0033] Specifically, the position of the deformable part 12 can be controlled by the control component 2, allowing the airbag 1 to deploy from a compressed state to a first deployment state, so that the airbag 1 can cover a larger area; or, the position of the deformable part 12 can be controlled by the control component 2, allowing the airbag 1 to deploy from a compressed state to a second deployment state, so that the airbag 1 can protect the passenger while avoiding other components. Thus, the airbag assembly 100 can cope with different operating conditions.

[0034] According to an embodiment of the present invention, the airbag assembly 100, by providing a deformable part 12 and a control component 2 that can be connected to the deformable part 12 to control the position of the deformable part 12, allows the airbag 1 to deploy to a first deployment state to cover a larger area, which helps to eliminate blind spots in protection, or to deploy to a second deployment state to avoid other components, thus preventing the airbag 1 from excessively compressing other components and causing additional damage. This enables the airbag assembly 100 to cope with different working conditions and improves the practicality of the airbag assembly 100.

[0035] In some embodiments of the present invention, such as Figures 1-3 As shown, the control component 2 includes a winder 21 and a pull cord 22. The winder 21 is connected to the pull cord 22 to be adapted to wind up or release the pull cord 22. The pull cord 22 extends into the airbag 1 and is connected to the deformable part 12. The winder 21 is adapted to control the airbag 1 to unfold to a first unfolded state or a second unfolded state by pulling the cord 22.

[0036] It should be noted that the length of the pull cord 22 in the first deployed state can be set to be greater than the length of the pull cord 22 in the second deployed state, so that the airbag 1 can have a larger coverage area in the first deployed state, and the airbag 1 can avoid other components in the second deployed state, so as to avoid the airbag 1 excessively compressing other components and causing additional damage.

[0037] Specifically, when vehicle 1000 collides, airbag 1 inflates, and winding device 21 releases a pull cord 22 of a first preset length. Deformation part 12 can pull the pull cord 22 away from winding device 21. When the pull cord 22 reaches its limit position, airbag 1 can deploy to the first deployed state, and winding device 21 can fix the pull cord 22 to control the position of airbag 1. When vehicle 1000 collides, airbag 1 inflates, and winding device 21 releases a pull cord 22 of a second preset length. Deformation part 12 can pull the pull cord 22 away from winding device 21. When the pull cord 22 reaches its limit position, airbag 1 can deploy to the first deployed state, and winding device 21 can fix the pull cord 22 to control the position of airbag 1. After the collision is completed, airbag 1 is in the deployed state (first deployed state or second deployed state). Winding device 21 can wind up the pull cord 22, and pull cord 22 can be pulled by deformation part 12 to retract the deployed airbag 1.

[0038] With the above settings, the airbag 1 can be stably deployed to the first deployment state or the second deployment state, ensuring the reliability of the airbag assembly 100. The control component 2 can pull the airbag 1 in the deployment state to retract, so as to avoid the airbag 1 continuously obstructing the passenger's vision, making it easier for the occupant to observe the current environment, and greatly improving the safety performance of the airbag assembly 100.

[0039] In some embodiments of the present invention, such as Figures 1-3 As shown, the pull rope 22 includes a main body 221 and a connecting part 222. The main body 221 is connected to the winder 21, and the connecting part 222 is connected to the deformable part 12. The width of the connecting part 222 is greater than the width of the main body 221. Preferably, the tensile strength of the material of the main body 221 can be set to be greater than the tensile strength of the material of the connecting part 222.

[0040] By adopting the above configuration, the connection area between the pull cord 22 and the deformable part 12 can be increased, thereby preventing the pull cord 22 and the deformable part 12 from separating due to excessive impact force, thus improving the reliability of the airbag assembly 100. In addition, when the pull cord 22 pulls the airbag 1 in the deployed state for retraction, the pull cord 22 can generate a wider stretching surface for the airbag 1 through the connecting part 222, which helps the airbag 1 to be retracted and prevents the unstretched parts on both sides of the deformable part 12 from drooping and causing obstruction.

[0041] In some embodiments of the present invention, such as Figures 1-3 As shown, in the direction away from the main body 221, the width of the connecting portion 222 can be gradually increased to construct the connecting portion 222 into a fan-shaped or fan-like structure. This effectively increases the connection area between the pull rope 22 and the deformable portion 12, and improves the structural stability of the connecting portion 222, ensuring the stability of the fit between the control component 2 and the airbag 1.

[0042] In some embodiments of the present invention, such as Figures 2-3 As shown, the airbag 1 is provided with an inflation port, an exhaust port 15 and a clearance port 13. The airbag 1 is adapted to be inflated through the inflation port and to be vented through the exhaust port 15. The clearance port 13, the inflation port and the exhaust port 15 are arranged at intervals. One end of the pull rope 22 is connected to the winder 21 and the other end passes through the clearance port 13 to be connected to the deformable part 12.

[0043] The above settings can prevent the airbag 1 from interfering with the pull rope 22 during the deformation process, which helps to ensure that the airbag 1 can be deployed in time and in place, thus improving the safety of the airbag assembly 100.

[0044] In some embodiments of the present invention, such as Figure 2 As shown, the pull rope 22 and the clearance opening 13 can be configured for a clearance fit, and the clearance between the pull rope 22 and the clearance opening 13 can be no greater than 2mm, such as 0.5mm, 1mm, 1.5mm, 2mm, etc. For example, the diameter of the main body 221 of the pull rope 22 can be set to 8mm-9mm, and the diameter of the clearance opening 13 can be set to 9mm-10mm.

[0045] With the above settings, the pull cord 22 can slide stably relative to the airbag 1, so as to ensure that the airbag 1 can deform smoothly, and to avoid excessive gas leakage caused by excessive gap between the pull cord 22 and the clearance opening 13, thus ensuring that the airbag 1 can effectively resist impact and improving the reliability of the airbag assembly 100.

[0046] In some embodiments of the present invention, such as Figures 2-3 As shown, the airbag 1 has a sealing protrusion 14 corresponding to the clearance opening 13. The sealing protrusion 14 is arranged around the clearance opening 13 and is sealed to the pull cord 22. This can further reduce the gas leakage at the clearance opening 13, ensuring the impact resistance of the airbag 1. In addition, the sealing protrusion 14 can also guide the pull cord 22 to ensure the smooth movement of the pull cord 22 and improve the reliability of the airbag assembly 100.

[0047] In some embodiments of the present invention, such as Figures 1-4 As shown, the airbag assembly 100 of this embodiment of the invention further includes a housing 3, with the airbag 1 and control component 2 mounted on the housing 3. This allows for an integrated design, reducing the installation difficulty of the airbag assembly 100, minimizing the space occupied by the airbag assembly 100, and improving the design rationality of the airbag assembly 100.

[0048] In some embodiments of the present invention, the control component 2 may be configured to pull the deployed airbag 1 back into the housing 3. This prevents the airbag 1 from continuously obstructing the passenger's view after a collision, allowing the passenger to accurately obtain current environmental information and thus implement the most suitable evasive strategy, such as pulling the vehicle 1000 to the side of the road or abandoning the vehicle, thereby improving passenger safety.

[0049] In some embodiments of the present invention, such as Figures 1-4 As shown, the housing 3 has a receiving cavity 33 and an airbag outlet 34 communicating with the receiving cavity 33. The airbag 1 is installed in the receiving cavity 33, and the airbag 1 is adapted to deploy or retract from the airbag outlet 34. Thus, the airbag 1 can be adequately protected to prevent the airbag 1 from failing to deploy due to damage, thereby improving the reliability of the airbag assembly 100.

[0050] In some embodiments of the present invention, such as Figures 1-4 As shown, the winder 21 is installed on the housing 3 and located outside the receiving cavity 33. The housing 3 has a connecting hole 35 communicating with the receiving cavity 33. The pull rope 22 is inserted into the receiving cavity 33, with one end of the pull rope 22 passing through the connecting hole 35 to connect with the winder 21, and the other end of the pull rope 22 connected to the deformable part 12. Through the above arrangement, the winder 21 and the airbag 1 can be arranged separately, which helps to prevent the winder 21 and the airbag 1 from interfering with each other and improves the operational stability of the airbag assembly 100.

[0051] In some embodiments of the present invention, such as Figure 4 As shown, the other end of the pull cord 22 can be passed through the airbag outlet 34 to connect with the deformable part 12. This allows the airbag 1 and the pull cord 22 to share the airbag outlet 34, which simplifies the structure of the housing 3, reduces processing difficulty and cost, and prevents the pull cord 22 from being restricted from the housing 3 when the deformable part 12 of the airbag 1 pulls the pull cord 22, ensuring the smooth movement of the pull cord 22 and improving the reliability of the airbag assembly 100.

[0052] Of course, the present invention is not limited to this. The winder 21 can also be disposed in the receiving cavity 33, and the winder 21 can be located on the side of the airbag 1 away from the airbag outlet 34. In this way, the structure of the airbag assembly 100 can be simplified, the processing difficulty of the airbag assembly 100 can be reduced, and the shell 3 can protect the winder 21, which helps to reduce the failure rate of the winder 21.

[0053] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the housing 3 includes a top cover 31 and a base 32. The top cover 31 is detachably mounted on the base 32 to define a receiving cavity 33 and an airbag outlet 34. The control assembly 2 is connected to the base 32, and the airbag 1 is mounted on the base 32 and disposed within the receiving cavity 33. Specifically, the top cover 31 and the base 32 can be detachably connected by connectors (bolts or screws). This reduces the molding difficulty of the housing 3 and improves the practicality of the airbag assembly 100.

[0054] The present invention also proposes a vehicle 1000.

[0055] like Figures 5-7 As shown, a vehicle 1000 according to an embodiment of the present invention includes: an airbag assembly 100 according to any of the above embodiments.

[0056] According to the embodiments of the present invention, the airbag assembly 100 of the vehicle 1000 can cope with different working conditions, improve the design rationality of the vehicle 1000, and enhance the overall performance of the vehicle 1000.

[0057] In some embodiments of the present invention, such as Figures 5-7 As shown, the vehicle 1000 of this embodiment of the invention also includes a body 200 and a steering wheel 300. The airbag assembly 100 is mounted on the top of the body 200. The steering wheel 300 is foldably mounted on the body 200. The steering wheel 300 has a folded state and an deployed state. The airbag 1 is adapted to deploy to a first deployed state when the steering wheel 300 is in the folded state, and the airbag 1 is adapted to deploy to a second deployed state when the steering wheel 300 is in the deployed state.

[0058] Specifically, when vehicle 1000 is involved in a collision, airbag 1 inflates, winding device 21 releases pull cord 22, and deformation part 12 can pull pull cord 22 to move away from winding device 21. If vehicle 1000 is in autonomous driving mode and steering wheel 300 is in a folded state, airbag 1 can deploy to the first deployment state. Airbag 1 in the first deployment state can fill the space left after steering wheel 300 is folded to eliminate blind spots. If vehicle 1000 is in manual driving mode and steering wheel 300 is in an deployed state, airbag 1 can deploy to the second deployment state. Airbag 1 in the second deployment state can avoid steering wheel 300 to prevent airbag 1 from excessively compressing steering wheel 300 and causing additional vehicle damage.

[0059] The above configuration allows the airbag assembly 100 to be adapted to the foldable steering wheel 300, which helps to better protect passengers and improves the reliability of the vehicle 1000.

[0060] This invention also proposes a control method for an airbag assembly.

[0061] like Figure 8 As shown, a control method for an airbag assembly according to an embodiment of the present invention is applied to an airbag assembly 100 according to any of the above embodiments. The control method includes: S10: When vehicle 1000 collides, control airbag 1 to deploy. That is, when vehicle 1000 collides, the explosive can be detonated, and the gas flow generated by the explosion can flow into airbag 1, causing airbag 1 to inflate and deploy.

[0062] S20: If the steering wheel 300 is in a folded state, control the airbag 1 to deploy to the first deployment state. That is, if the vehicle 1000 is in autonomous driving mode, it can be determined that the steering wheel 300 is in a folded state. At this time, the airbag 1 can be controlled to deploy from the compressed state to the first deployment state. The airbag 1 in the first deployment state can fill the space left after the steering wheel 300 is folded to eliminate the blind spot of protection.

[0063] S30: If the steering wheel 300 is in the deployed state, control the airbag 1 to deploy to the second deployment state. That is, if the vehicle 1000 is in manual driving mode, it can be determined that the steering wheel 300 is in the deployed state. At this time, the airbag 1 can be controlled to deploy from the compressed state to the second deployment state. The airbag 1 in the second deployment state can avoid the steering wheel 300, so as to avoid the airbag 1 excessively compressing the steering wheel 300 and causing additional vehicle damage.

[0064] The airbag assembly control method according to the present invention enables the airbag assembly 100 to cope with different working conditions, which helps to better protect passengers and improve driving safety.
