The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0031] First, refer to Figure 1-Figure 6 A vehicle according to an embodiment of the second aspect of the utility model is briefly described. The vehicle includes the airbag 100 according to the embodiment of the first aspect of the utility model.
[0032] The vehicle according to the embodiment of the utility model comprises: a body sheet metal 200, a roof 300 and an airbag 100 according to the embodiment of the first aspect of the utility model, wherein the roof 300 is arranged on the inner side of the body sheet metal 200, a weakened portion is formed on the roof 300, and the airbag 100 is arranged between the weakened portion and the body sheet metal 200. Thus, the structure is simple, the design is ingenious, and the safety of the occupants can be well protected.
[0033] According to the vehicle of the embodiment of the utility model, by setting the airbag 100 according to the embodiment of the first aspect of the utility model, the safety factor of the vehicle is improved, the safety of the driver and passengers in different riding scenarios is ensured, and the installation structure of the airbag 100 is simple, which reduces the difficulty of assembling the vehicle and improves the production efficiency of the vehicle.
[0034] Reference below Figure 1-Figure 6 An airbag 100 according to an embodiment of the first aspect of the present invention is described.
[0035] like Figure 1-Figure 3 As shown, the airbag 100 according to the first embodiment of the utility model includes: a shell 1, an airbag 2 and a gas generator 3.
[0036] Specifically, the airbag 100 is arranged on the roof 300 of the vehicle, and a housing 1 defines a receiving cavity, and the airbag 2 is arranged in the receiving cavity. The airbag 2 has a folded state and an inflated state. The gas generator 3 is arranged in the receiving cavity and connected to the airbag 2, and is used to inflate the airbag 2. When the airbag 2 is in the folded state, the airbag 2 is completely located in the receiving cavity. When the gas generator 3 inflates the airbag 2, the airbag 2 switches from the folded state to the inflated state, and the airbag 2 extends out of the housing 1 and is located outside the receiving cavity. The inflated state includes a switchable first inflated state and a second inflated state. Therefore, the airbag 100 has a simple structure and can effectively protect the driver and passengers from injury.
[0037] It can be understood that the gas generator 3 inflates the airbag 2, and the airbag 2 switches from a folded state to an inflated state. When the driver and passengers are in a social and leisure state and the distance is relatively close, the airbag 2 is in the first inflated state. When the driver and passengers are in a social and leisure state and the distance is relatively far, the airbag 2 switches from the first inflated state to the second inflated state.
[0038] According to the airbag 100 of the embodiment of the utility model, by providing an airbag 2 that can switch from a first inflation state to a second inflation state, it plays a role in protecting the driver and passengers in a collision accident, ensuring the safety of the driver and passengers in different riding scenarios. In addition, the installation structure of the airbag 100 is simple, which reduces the difficulty of assembling the airbag 100 and improves the assembly efficiency. The design is ingenious and the production cost is low.
[0039] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, when the airbag 2 is in the inflated state, the airbag 2 unfolds to form an inflatable cavity. When the airbag 2 is in the first inflated state, the gas fills the first cavity 21 of the inflatable cavity. When the airbag 2 is in the second inflated state, the gas fills the first cavity 21 and the second cavity 22 of the inflatable cavity. The second cavity 22 is connected to both ends of the first cavity 21 and communicates with the first cavity 21. Thus, when the driver and the passenger are in a social and leisure state and the distance is relatively close, the airbag 2 is in the first inflated state, and the gas fills the first cavity 21 of the inflatable cavity. When the driver and the passenger are in a social and leisure state and the distance is relatively far, the airbag 2 switches from the first inflated state to the second inflated state, and the gas fills the first cavity 21 and the second cavity 22 of the inflatable cavity, thereby ensuring the safety of the driver and the passenger in different riding scenarios. The airbag 100 of this embodiment can effectively protect different riding scenarios.
[0040] In some embodiments of the utility model, a tensioning member is provided in the airbag 2, and when the airbag 2 is in the first inflation state, the two ends of the tensioning member are respectively connected to the two ends of the airbag 2, and when the airbag 2 is in the second inflation state, the tensioning member is separated from the airbag 2. Specifically, the tensioning member is cut off by detonating high-temperature gas, so that the airbag 2 is switched from the first inflation state to the second inflation state, effectively protecting the occupant who is at a position with a relatively large seat travel distance.
[0041] In some embodiments of the present invention, the housing 1 includes: a housing 11 and a cover plate 12. The housing 11 and the cover plate 12 cooperate to define a receiving cavity. A grille hole 121 is formed on the cover plate 12. The receiving cavity is connected to the outside through the grille hole 121. Therefore, the provision of the grille hole 121 weakens the structure of the cover plate 12, which is conducive to the deployment of the airbag 2, and reduces the overall weight of the safety airbag 100, thereby preventing the airbag 2 from rubbing against the ceiling 300.
[0042] In some embodiments of the present invention, mounting plates 13 are connected to the outer sides of both ends of the housing 11, mounting holes are formed on the mounting plates 13, and the housing 11 is fixed to the vehicle through fasteners passing through the mounting holes. Thus, the connection method between the airbag 100 and the body sheet metal 200 is simple, which reduces the difficulty of assembling the airbag 100 and the vehicle.
[0043] In some embodiments of the present invention, the airbag 100 further includes: a connecting piece, the connecting piece is connected between the gas generator 3 and the housing 11, and / or the connecting piece is connected between the airbag 2 and the housing 11. Preferably, the connecting piece is a fastener, thereby reducing production costs and facilitating assembly.
[0044] In some embodiments of the present invention, the housing 11 is formed as a metal part, so that the structure of the metal part is stable and not easily deformed.
[0045] In some embodiments of the utility model, the airbag 100 further includes: a sensing module, the sensing module includes: a camera and a position sensor, the camera is used to detect the occupant's posture, and the position sensor is used to detect the seat position. Preferably, the camera is a camera of an OMS (Occupancy Monitoring System) or a DMS (Driver Monitor System), and the position sensor can sense the seat position.
[0046] In some embodiments of the utility model, the airbag 100 also includes: a control module, which is electrically connected to the sensing module and the gas generator 3. The control module receives the signal transmitted by the sensing module, and sends an instruction to the ECU after analysis and judgment. The ECU is electrically connected to the airbag 100 and sends an inflation instruction to the gas generator 3.
[0047] The vehicle according to the second embodiment of the utility model includes the airbag 100 according to the first embodiment of the utility model.
[0048] Specifically, the vehicle includes: a body sheet metal 200, a roof 300 and an airbag 100 according to the first embodiment of the utility model.
