[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0050] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the term "width direction" is based on the attached Figure 2 The orientation or position relationship shown is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0051] In the related art, when the front passenger passenger tilts the passenger seat backwards, forming a nearly semi-reclining sitting position, the restraining function of the seat belt is limited, and the lateral restraint on the upper body of the front passenger passenger is insufficient. If a sudden side collision occurs during driving, the seat belt at this time cannot effectively protect the front passenger passenger, and the support force provided by the side airbag alone is difficult to meet the lateral support requirements for the front passenger passenger.

[0052] In this regard, an embodiment of the present application provides an airbag assembly for providing lateral support to a front passenger occupant.

[0053] The present application also provides a vehicle, please refer to Figure 1 and Figure 2 The vehicle includes a passenger seat 10 , a driver seat 20 , an airbag assembly and an armrest box 50 .

[0054] It is understandable that the passenger seat 10 is used for passengers to sit, and the backrest of the passenger seat 10 can be tilted backwards, so that the passenger on the passenger seat 10 enters a semi-lying sitting state, thereby improving the sitting comfort. The main driver's seat 20 is arranged on one side of the passenger seat 10 for the driver to sit.

[0055] The airbag assembly is disposed between the passenger seat 10 and the driver seat 20. The airbag assembly includes a side airbag 30 and a support airbag 40. The side airbag 30 has a folded state and an inflated state. The side airbag 30 is used to extend between the passenger seat 10 and the driver seat 20 of the vehicle in the inflated state to provide lateral support to the occupant on the passenger seat 10 when a lateral collision occurs.

[0056] The support airbag 40 has a folded state and an inflated state. The support airbag 40 is used to support the inflated side of the side airbag 30 close to the driver's seat 20. In other words, the support airbag 40 in the inflated state supports the inflated side of the side airbag 30 away from the passenger seat 10, thereby providing support for the side airbag 30 and enhancing the supporting effect of the side airbag 30 on the passenger seat 10.

[0057] It is understandable that, when the passenger seat 10 is in a rearward tilted state, the inflated support airbag 40 and the inflated side airbag 30 are at least partially in contact with each other in the vehicle width direction. In this way, in a side collision, the support airbag 40 can be supported on the inflated side airbag 30.

[0058] In some embodiments, when the passenger seat 10 is in a non-rearward-tilted state, the inflated support airbag 40 is at least partially in contact with the inflated side airbag 30 along the width direction of the vehicle. In this way, when a lateral collision occurs in the non-rearward-tilted state, the support airbag 40 can also be supported on the inflated side airbag 30.

[0059] In some embodiments, the side of the inflated support airbag 40 facing away from the side airbag 30 abuts against the driver's seat 20 , and the support airbag 40 is supported by the driver's seat 20 , thereby improving the support effect of the inflated side airbag 30 .

[0060] It should be noted that the support airbag 40 in the inflated state can also be supported on the side airbag 30 by relying on its own rigidity in the inflated state.

[0061] When a side collision occurs in the airbag assembly of the embodiment of the present application, the side airbag 30 and the support airbag 40 enter the inflated state. When in the inflated state, the side airbag 30 extends between the passenger seat 10 and the driver's seat 20 to support the upper body of the passenger and limit the lateral displacement of the upper body. When in the inflated state, the support airbag 40 supports the side of the inflated side airbag 30 close to the driver's seat 20, thereby increasing the lateral support force of the side airbag 30 on the upper body of the passenger and preventing the upper body of the passenger, especially the head, from colliding with the driver's seat 20.

[0062] Exemplarily, the vehicle includes an armrest box 50 disposed between the passenger seat 10 and the driver seat 20 , and the support airbag 40 may be disposed on the driver seat 20 , or on the armrest box 50 between the passenger seat 10 and the driver seat 20 .

[0063] In some embodiments, the support airbag 40 is disposed in the armrest box 50 , and the inflation direction of the support airbag 40 is upward, so that the inflation process of the support airbag 40 will not cause secondary injuries to surrounding passengers.

[0064] It is understandable that the specific position of the support airbag 40 on the armrest box 50 is not limited, as long as it can support the inflated side airbag 30 .

[0065] For some examples, please refer to Figure 3 and Figure 4 The support airbag 40 is accommodated in the second installation box 51 and expands out of the second installation box 51 after being inflated. In order to install the second installation box 51, a groove 52 is provided at the rear end of the top surface of the armrest box 50, and the second installation box 51 is arranged in the groove 52.

[0066] Exemplarily, along the driving direction of the vehicle, the support airbag 40 is arranged at the rear end of the armrest box 50. The rear end of the armrest box 50 is an end where the air outlet of the air conditioner is arranged. In other words, there is an installation area for arranging the support airbag 40 at the rear end of the armrest box 50. The installation area can be arranged on the top surface of the rear end of the armrest box 50.

[0067] It should be understood that since the side airbag 30 will move with the adjustment of the tilt angle of the passenger seat 10, setting the support airbag 40 at the rear end of the armrest box 50 can make the support airbag 40 closer to the position of the side airbag 30 when the passenger seat 10 is in a tilted state. In this way, the support airbag 40 can support the side airbag 30 when the passenger seat 10 is at different tilt angles with a relatively smaller volume.

[0068] It is understandable that the volume of the support airbag 40 and the side airbag 30 in the inflated state is not limited. In some embodiments, the volume of the support airbag 40 in the inflated state is smaller than the volume of the side airbag 30 in the inflated state, that is, the side airbag 30 can be inflated to the maximum in a shorter time. It should be noted that since the side airbag 30 will be inflated before the support airbag 40 when the support airbag 40 and the side airbag 30 are inflated, setting the volume of the support airbag 40 to be smaller can shorten its inflation time, making it easier to achieve that the two are inflated to the maximum volume at the same time point, so as to provide better support for the occupant.

[0069] Understandably, please refer to Figure 5 and Figure 6 The installation structure of the side airbag 30 is not limited, for example, it can be installed on the backrest frame 11 of the passenger seat 10. In some embodiments, the passenger seat 10 includes a backrest frame 11 and a mounting portion 12 disposed on the backrest frame 11 near the driver's seat 20, the mounting portion 12 at least partially protrudes toward the driver's seat 20, and the side airbag 30 is accommodated in the mounting portion 12. Inflate the side airbag 30, the side airbag 30 is inflated and bulges out from the mounting portion 12.

[0070] The mounting portion 12 may be a first mounting box 121 mounted on the backrest frame 11 and a side plate 122 connected to the first mounting box 121. The side plate 122 is screwed to the backrest frame 11, and the side plate 122 at least partially protrudes from the backrest frame 11 toward the driver's seat 20, and the first mounting box 121 is disposed on the protruding portion of the side plate 122.

[0071] Exemplarily, the vehicle includes a first inflatable member, a second inflatable member, and a control component, wherein the first inflatable member is used to switch the side airbag from a folded state to an inflated state, and the second inflatable member is used to switch the support airbag from a folded state to an inflated state. It is understandable that the first inflatable member and the second inflatable member are gas generators, which are used to generate gas to inflate the side airbag and the support airbag under the control of the control component. The gas generator can be an air pump with compressed air, or a gas generating structure with solid fuel, wherein the solid fuel can be ignited to generate gas.

[0072] In some embodiments, the vehicle includes an air pressure sensor, which is used to obtain the air pressure change value in the vehicle door, thereby obtaining the air pressure change in the door cavity caused by the impact. The air pressure sensor, the first inflatable member, and the second inflatable member are all connected to the control component signal. In this way, the control component can receive the signal of the air pressure sensor to control the first inflatable member and the second inflatable member. And / or,

[0073] The vehicle includes an acceleration sensor, which is used to detect the acceleration change value of the vehicle, so as to obtain the acceleration change caused by the impact. The acceleration sensor, the first inflatable member, and the second inflatable member are all connected to the control component signal. In this way, the control component can receive the signal of the acceleration sensor to control the first inflatable member and the second inflatable member. And / or,

[0074] The vehicle includes an angle sensor, which is used to obtain the tilt angle value of the passenger seat to determine the tilt degree of the backrest of the passenger seat 10. The angle sensor, the first inflatable member, and the second inflatable member are all connected to the control component signal. In this way, the control component can receive the signal of the angle sensor to control the first inflatable member and the second inflatable member.

[0075] It is understandable that the vehicle is provided with one or more of an air pressure sensor, an acceleration sensor, and an angle sensor.

[0076] The combination of the above-mentioned air pressure sensor, acceleration sensor, and angle sensor on the vehicle is further described through the following three embodiments:

[0077] In some embodiments, the vehicle includes a control component, an air pressure sensor, and an angle sensor. The air pressure sensor is used to obtain the air pressure change value in the vehicle door, and the angle sensor is used to obtain the tilt angle value of the passenger seat 10. The control component controls the inflation of the side airbag 30 and the support airbag 40 according to the air pressure change value and the tilt angle value.

[0078] In some embodiments, the vehicle includes a control component, an acceleration sensor, and an angle sensor. The acceleration sensor is used to detect the acceleration change value of the vehicle, and the angle sensor is used to obtain the tilt angle value of the passenger seat 10. The control component controls the inflation of the side airbag 30 and the support airbag 40 according to the acceleration change value and the tilt angle value.

[0079] In some embodiments, the vehicle includes a control component, an air pressure sensor, an acceleration sensor, and an angle sensor, wherein the acceleration sensor is used to detect the acceleration change value of the vehicle, the air pressure sensor is used to obtain the air pressure change value in the vehicle door, and the angle sensor is used to obtain the tilt angle value of the passenger seat 10. The control component controls the inflation of the side airbag 30 and the support airbag 40 according to the air pressure change value, the acceleration change value, and the tilt angle value.

[0080] It should be noted that when the car door is hit from the side, the air pressure sensor can detect the changes in air pressure in the door cavity, which is faster than the detection speed of the acceleration sensor, thereby better protecting the passengers.

[0081] Please refer to Figure 7 The embodiment of the present application also discloses an airbag control method, which is applicable to a vehicle. The airbag control method includes:

[0082] S1 receives the side collision information value.

[0083] It is understandable that the side collision information value is a detection value of the severity of the side collision of the vehicle. The larger the side collision information value, the more serious the side collision of the vehicle. The side collision information value can be detected and obtained by a sensor such as an air pressure sensor or an acceleration sensor.

[0084] S2 receives the tilt angle value of the passenger seat 10 .

[0085] The tilt angle value of the passenger seat 10 is a detection value of the rearward tilt degree of the passenger seat 10 backrest. The larger the tilt angle value, the larger the rearward tilt angle of the passenger seat 10 backrest. The tilt angle value can be obtained by a sensor such as an angle sensor.

[0086] S3 compares the side collision information value with a preset value, and compares the tilt angle value with a preset angle value.

[0087] S4 controls the inflation of the side airbag 30 and the support airbag 40 according to the comparison result.

[0088] The airbag control method of the embodiment of the present application can control the inflation of the side airbag 30 and the support airbag 40 according to the severity of the lateral collision and the rearward tilt angle of the passenger seat 10, so as to avoid unnecessary harm and loss caused by the inflation of the side airbag 30 and / or the support airbag in scenarios where the collision is not serious or the passenger seat 10 does not tilt backward.

[0089] It should be noted that since the inflation time of the side airbag 30 and the support airbag 40 is within tens of milliseconds, such a fast inflation speed is likely to cause secondary injuries to the passengers. Therefore, in a collision accident, it is not that both the side airbag 30 and the support airbag 40 are inflated to better protect the safety of the passengers, but it is necessary to selectively inflate the side airbag 30 and the support airbag 40 according to the severity of the side collision.

[0090] Exemplarily, step S4 includes at least one of the following:

[0091] S41 If the side collision information value is greater than or equal to the first preset value, and the tilt angle value is greater than or equal to the preset angle value, the collision severity is large, and the rearward tilt of the passenger seat 10 is large. The side airbag 30 and the support airbag 40 are controlled to inflate, so as to effectively limit the lateral displacement of the occupant's upper body and better protect the occupant's head and neck.

[0092] S42: If the side collision information value is greater than or equal to the first preset value and the tilt angle value is less than the preset angle value, the side airbag 30 is controlled to inflate and the support airbag 40 is not inflated. It can be understood that at this time, the passenger seat 10 is not tilted backward to a large extent, and the occupant can be effectively protected by the seat belt and the side airbag 30.

[0093] S43: If the side collision information value is less than the first preset value and greater than or equal to the second preset value, the side airbag 30 is controlled to inflate, wherein the first preset value is greater than the second preset value. It can be understood that under this collision degree, if the tilt angle of the passenger seat 10 is greater than the preset angle value or less than the preset angle value, it is not necessary to inflate the support airbag 40, and the seat belt and the side airbag 30 can effectively protect the occupant.

[0094] S44: If the side collision information value is less than the second preset value, the side airbag 30 and the support airbag 40 are not inflated. It can be understood that the collision intensity is relatively low, and the occupant's body can be protected only by the seat belt.

[0095] It can be understood that step S3 may include one of steps S41, S42, S43, and S44, or may include multiple steps S41, S42, S43, and S44, for example, 2, 3, or 4.

[0096] In some embodiments, in step S41 , the time point for controlling the inflation of the support airbag 40 is the same as the time point for controlling the inflation of the side airbag 30 .

[0097] In some embodiments, step S41 includes:

[0098] S411 If the side collision information value is greater than or equal to the first preset value, and the tilt angle value is greater than or equal to the preset angle value, the side airbag 30 and the support airbag 40 are controlled to inflate in sequence. That is, the inflation time points of the side airbag 30 and the support airbag 40 are controlled to be different, and the inflation time point of the side airbag 30 is controlled to be earlier than the inflation time point of the support airbag 40, so as to avoid interference between the side airbag 30 and the support airbag 40 during the inflation process.

[0099] There is a time interval between the time point of controlling the inflation of the side airbag 30 and the time point of controlling the inflation of the support airbag 40, and the sum of the time interval and the inflation time of the support airbag 40 is equal to the inflation time of the side airbag 30. It should be noted that the support force of the support airbag 40 and the side airbag 30 is the strongest when they are inflated to the maximum volume. The above embodiment can make the time point of the maximum volume of the two be the same, thereby providing stronger support for the occupant.

[0100] For example, the inflation time of the side airbag 30 is 20ms, that is, the side airbag 30 is filled within 20ms. After the side airbag 30 is inflated for 5ms, the support airbag 40 is inflated, and the support airbag 40 is filled within 15ms, thereby providing the side airbag 30 with sufficient lateral support force.

[0101] In order to accurately control the inflation time, after receiving the side collision information value, the inflation of the side airbag 30 can be controlled within 2ms.

[0102] In some embodiments, the side collision information value includes at least one of a collision acceleration change value and a collision air pressure change value. This is further described below:

[0103] If the side collision information value includes the collision acceleration change value, it is understandable that the collision acceleration change value is obtained by an acceleration sensor arranged on the vehicle, and in order to avoid the deformation of the vehicle in the collision affecting the reliability of the data, the acceleration sensor can be arranged on the vehicle frame.

[0104] Correspondingly, the first preset value includes a first preset acceleration change value corresponding to the collision acceleration change value, and the second preset value includes a second preset acceleration change value corresponding to the collision acceleration change value. The first preset acceleration change value is greater than the second preset acceleration change value. In some embodiments, the first preset acceleration change value is 150%, and the second preset acceleration change value is 30%.

[0105] If the side collision information value is a collision air pressure change value, it is understandable that the collision air pressure change value is obtained by an air pressure sensor arranged in the cavity of the vehicle door.

[0106] Correspondingly, the first preset value includes a first preset pressure change value corresponding to the collision pressure change value, and the second preset value includes a second preset pressure change value corresponding to the collision pressure change value. In some embodiments, the first preset pressure change value is 40%, and the second preset pressure change value is 15%.

[0107] In some embodiments, the preset angle value is obtained by an angle sensor installed on the vehicle. The preset angle value is 35°.

[0108] It should be noted that the first preset value and the second preset value can be adjusted according to the setting position of the acceleration sensor, or the setting position of the air pressure sensor, the cavity volume, and the sealing condition. The preset angle value can be adjusted according to the setting position of the angle sensor.

[0109] In some embodiments, the vehicle can receive a collision acceleration change value and a collision air pressure change value.

[0110] In step S1, the collision acceleration change value and the collision pressure change value that are received first are used as the side collision information value. That is, if the collision acceleration change value is received first, the collision acceleration change value is used as the side collision information value. If the collision pressure change value is received first, the collision pressure change value is used as the side collision information value.

[0111] It is understandable that if the vehicle is equipped with an acceleration sensor, in step S1, the collision acceleration change value is received, and the collision acceleration change value is used as the side collision information value. If the vehicle is equipped with an acceleration sensor and an air pressure sensor, and the collision area is far away from the door, the air pressure sensor cannot obtain the air pressure change. In step S1, the collision acceleration change value is received, and the collision acceleration change value is used as the side collision information value.

[0112] If the vehicle is equipped with an air pressure sensor, in step S1, the collision air pressure change value is received, and the collision air pressure change value is used as the side collision information value. If the vehicle is equipped with an acceleration sensor and an air pressure sensor, and the collision area is on the door, the time point at which the air pressure sensor obtains the air pressure change is earlier than the time point at which the acceleration sensor obtains the acceleration change, and in step S1, the collision air pressure change value is received, and the collision air pressure change value is used as the side collision information value.

[0113] An embodiment of the present application also provides a storage medium, which stores computer-executable instructions. The computer-executable instructions can be executed by a processor to implement the steps of the airbag control method.

[0114] An embodiment of the present application further provides an airbag system, which includes a first receiving module, a second receiving module, a comparing module, and a control module.

[0115] The first receiving module is used for receiving the side collision information value.

[0116] The second receiving module is used to receive the tilt angle value of the passenger seat 10 .

[0117] The comparison module is used to compare the side collision information value with the first preset value, and to compare the tilt angle value with the preset angle value.

[0118] The control module is used to control the inflation of the side airbag 30 and the support airbag 40 according to the comparison result.

[0119] An embodiment of the present application further provides an airbag device, which includes a memory and a processor.

[0120] The memory is used to store computer executable instructions.

[0121] The processor is used to execute the computer executable instructions to perform the steps of the airbag control method.
