[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0029] The following is for reference. Figures 1-4The roof safety curtain 100 according to an embodiment of this application is applied to a vehicle 1000 and installed on the roof 200 of the vehicle 1000. The roof safety curtain 100 can form a protective structure on the top of the passenger compartment to improve the safety performance of the vehicle 1000 under specific working conditions and improve the protection effect of the vehicle 1000 on the driver and passengers.

[0030] According to an embodiment of this application, the roof safety curtain 100 includes a first safety curtain 1 and a second safety curtain 2. The first safety curtain 1 is disposed at the middle crossbeam 210 of the roof 200, and the first safety curtain 1 can be deployed from the middle crossbeam 210 toward the front of the vehicle 1000, thereby forming a protective structure in the area of ​​the middle crossbeam in the roof 200 to protect the heads of the front-seat occupants of the vehicle 1000. The second safety curtain 2 is disposed at the middle crossbeam 210 of the roof 200, and the second safety curtain 2 can be deployed from the middle crossbeam 210 toward the rear of the vehicle 1000, thereby forming a protective structure in the area of ​​the middle crossbeam in the roof 200 to protect the heads of the rear-seat occupants of the vehicle 1000.

[0031] The "central crossbeam 210" is located in the middle of the top cover 200 in the front-rear direction (i.e., the X direction) and extends along the left-right direction (i.e., the Y direction) of the vehicle 1000.

[0032] Reference Figure 1 As shown, the first safety curtain 1 and the second safety curtain 2 are normally in a retracted state, and the first safety curtain 1 and the second safety curtain 2 are deployed when the vehicle 1000 reaches preset conditions, so as to form a protective structure on the top of the passenger compartment when the vehicle 1000 is in a specific working condition, thereby protecting the driver and passengers.

[0033] It should be noted that the aforementioned "preset conditions" refer to the conditions that trigger the roof safety curtain 100 to switch from the retracted state to the deployed state, such as: the roof cover 200 being hit by a collision or impact, etc. The preset conditions include but are not limited to these, and the specific triggering conditions can be set according to the safety protection requirements of the vehicle 1000.

[0034] The vehicle 1000 may be equipped with acceleration sensors, pressure sensors, etc. Taking the acceleration sensor as an example, when the acceleration sensor located at the roof safety curtain 100 reaches a certain acceleration, it can trigger the roof safety curtain 100 to switch to the deployed state. The triggering method of the roof safety curtain 100 is the same as the triggering method of the airbags in other areas of the vehicle 1000 (such as the steering wheel, passenger seat, etc.), and will not be described in detail here.

[0035] Currently, vehicles 1000 protect occupants by installing airbags, which are distributed throughout the vehicle 1000 to provide adequate protection for the passengers in the passenger compartment. However, in related technologies, the airbags in vehicles 1000 are typically positioned laterally to the occupants, such as on the front, left, or right sides, lacking roof protection. If the vehicle 1000 overturns due to a collision or impact, causing the roof 200 to deform, the occupants inside the vehicle 1000 are vulnerable to injury from the strong impact at the roof 200.

[0036] In this application, the roof safety curtain 100 is installed on the roof 200 of the vehicle 1000. The first safety curtain 1 and the second safety curtain 2 can be deployed from the central crossbeam 210 of the roof 200 of the vehicle 1000 towards the front and rear sides of the vehicle 1000, respectively, to form a protective structure on the top of the passenger compartment. The roof safety curtain 100 can effectively buffer the impact between the head of the driver and passenger and the roof 200, preventing the driver and passenger from being injured by the impact from one side of the roof 200, thus helping to improve the driving and riding safety of the vehicle 1000. At the same time, the first safety curtain 1 and the second safety curtain 2 can be quickly deployed forward and rearward from the middle area of ​​the top of the passenger compartment, respectively, shortening the time required for the roof safety curtain 100 to fully deploy, with a fast response speed, thereby further improving the protective effect of the roof safety curtain 100 on the driver and passenger.

[0037] In some embodiments of this application, the vehicle 1000 has multiple driver and passenger seats, each of which can be used for passengers to sit.

[0038] The first safety curtain airbag 1 is provided with a first clearance position 101. When the first safety curtain airbag 1 is in the deployed state, the first clearance position 101 is corresponding to at least one driver or passenger seat. The first clearance position 101 is recessed upward from the surface of the first safety curtain airbag 1 opposite to the driver or passenger seat, so that the first clearance position 101 can provide a certain clearance for the driver or passenger below it, so as to leave a certain space between the head of the driver or passenger and the first safety curtain airbag 1, and prevent the driver or passenger from suffocating when the first safety curtain airbag 1 is protecting the driver or passenger. The second safety curtain 2 is provided with a second avoidance position 201. When the second safety curtain 2 is in the deployed state, the second avoidance position 201 is set corresponding to at least one driver or passenger seat. The second avoidance position 201 is recessed upward from the two side surfaces of the second safety curtain 2 opposite to the driver or passenger seat. Thus, the second avoidance position 201 can play a certain avoidance role for the driver or passenger located below it, so as to leave a certain space between the head of the driver or passenger and the second safety curtain 2, and prevent the driver or passenger from suffocating when the second safety curtain 2 is protecting the safety of the driver or passenger.

[0039] Understandably, the roof safety curtain 100 is filled with gas in the triggered state (i.e., deployed state) to cushion the impact force. Therefore, after the roof safety curtain 100 is triggered, it can fit against part of the occupant's limbs, and the avoidance structures (i.e., the first avoidance position 101 and the second avoidance position 201 mentioned above) can engage with the occupant's head, leaving a certain gap between the occupant and the roof safety curtain 100 to meet the occupant's breathing needs when in contact with the roof safety curtain 100.

[0040] Reference Figure 2 As shown, in some embodiments of this application, there are multiple first clearance positions 101.

[0041] Among them, multiple first avoidance positions 101 are respectively set up one-to-one with multiple driver and passenger positions, so that when the first safety curtain 1 works with the driver and passenger in each driver and passenger position, it can protect each driver and passenger while ensuring their breathing needs.

[0042] Reference Figure 2 As shown, in some other embodiments of this application, there are multiple second clearance positions 201.

[0043] Among them, multiple second avoidance positions 201 are respectively set up one-to-one with multiple driver and passenger positions, so that when the second safety curtain 2 works with the driver and passenger in each driver and passenger position, it can protect each driver and passenger while ensuring their breathing needs.

[0044] It should be noted that there are multiple first avoidance positions 101 and second avoidance positions 201. When the roof safety curtain 100 is deployed, the roof safety curtain 100 can form multiple avoidance structures corresponding to the driver and passenger positions on the top of the passenger compartment to meet the breathing needs of the driver and passenger in each driver and passenger position.

[0045] In some other embodiments of this application, the first clearance position 101 extends along the Y direction of the vehicle 1000, and the first clearance position 101 is correspondingly provided with multiple driver and passenger seats so that the driver and passenger occupants at multiple driver and passenger seats can be cleared simultaneously by one first clearance position 101.

[0046] In some embodiments of this application, the second avoidance position 201 extends along the Y direction of the vehicle 1000, and the second avoidance position 201 is correspondingly provided with multiple driver and passenger seats so as to simultaneously avoid the drivers and passengers in multiple driver and passenger seats through a second avoidance part.

[0047] Understandably, vehicle 1000 typically has multiple driver and passenger seats, each for the use of occupants. Taking vehicle 1000 with five driver and passenger seats as an example, there are two driver and passenger seats at the front of the passenger compartment. The first safety curtain airbag 1 is arranged corresponding to the two driver and passenger seats. When the first safety curtain airbag 1 is deployed, the first clearance seat 101 extends along the left and right direction of vehicle 1000 and is located above the two driver and passenger seats. When the first safety curtain airbag 1 protects the occupants at the two driver and passenger seats, the first clearance seat 101 can simultaneously meet the breathing needs of the two occupants. Meanwhile, there are three driving and passenger seats arranged sequentially along the width of the vehicle 1000 on the rear side of the passenger compartment. When the second safety curtain 2 is deployed, the second clearance position 201 is located above the three driving and passenger seats. While the second safety curtain 2 protects the occupants in the three driving and passenger seats, the second clearance position 201 can simultaneously meet the breathing needs of the three occupants.

[0048] like Figure 4 As shown, in some embodiments of this application, the first safety curtain 1 has a plurality of first inflation units 11 arranged in an array, and the first safety curtain 1 is adapted to deploy when the first inflation units 11 are inflated; the second safety curtain 2 has a plurality of second inflation units 21 arranged in an array, and the second safety curtain 2 is adapted to deploy when the second inflation units 21 are inflated.

[0049] Understandably, by incorporating multiple inflation units into the roof safety curtain 100, the response and deployment rate of the roof safety curtain 100 can be improved. For example, in a large airbag space, the time required for gas to be generated, filling the airbag and driving its deployment is T1. In an airbag of the same volume but composed of multiple sub-spaces, gas can be generated in each sub-space, and the time required for gas to fill the airbag and drive its deployment is T2, where T2 < T1. This ensures the response efficiency of the roof safety curtain 100.

[0050] Meanwhile, when the roof safety curtain 100 is composed of multiple inflatable units, its reliability can be improved. Understandably, because the roof safety curtain 100 has multiple inflatable units, even if individual inflatable units fail, the roof safety curtain 100 can still meet its deployment requirements, thereby improving its reliability.

[0051] In some embodiments of this application, the roof safety curtain 100 may be made of a cut-resistant material, such as PET (polyethylene terephthalate) film. PET film has good flexibility and can prevent damage from collisions, compression, or sheet metal scratches, thus improving the reliability of the roof safety curtain 100. It should be noted that the material of the roof safety curtain 100 is not limited to this; it may also be other fabric materials, etc., and is not specifically limited here.

[0052] In some embodiments of this application, the first safety curtain 1 is arranged in a rolled or folded manner, so that the first safety curtain 1 can be stored by rolling or folding, so as to store the first safety curtain 1 at the top cover 200 of the vehicle 1000.

[0053] In some embodiments of this application, the second safety curtain 2 is arranged in a rolled or folded manner, so that the second safety curtain 2 can be stored in the roof 200 of the vehicle 1000 by rolling or folding.

[0054] It should be noted that the winding or folding method of the first safety curtain 1 and the second safety curtain 2 is not specifically limited here, but preferably a winding or folding method that facilitates the rapid unfolding of the first safety curtain 1 and the second safety curtain 2.

[0055] In some embodiments of this application, the first safety curtain 1 and the second safety curtain 2 are integrated, so that the first safety curtain 1 and the second safety curtain 2 can be housed and arranged in the same storage space, which facilitates the storage and arrangement of the roof safety curtain 100 at the top cover 200.

[0056] In some embodiments of this application, the roof safety curtain 100 further includes a connecting part for connecting to the central crossbeam 210 to connect and fix the roof safety curtain 100 to the central crossbeam 210 of the vehicle 1000, so as to facilitate the storage and fixation of the roof safety curtain 100 when it is in the storage state. At the same time, the connecting part can keep the roof safety curtain 100 in the position of the top cover 200 when the roof safety curtain 100 is in the triggered state, so as to ensure the deployment effect of the roof safety curtain 100.

[0057] The connecting part can be constructed as a connecting rod or other connecting structure, and no specific limitation is made here. At the same time, the connection method between the connecting part and the central crossbeam 210 can include, but is not limited to, bonding, screwing, etc.

[0058] The vehicle 1000 according to the embodiments of this application includes the roof safety curtain 100 described above. The roof safety curtain 100 can form a protective structure on the top of the passenger compartment to improve the safety of the vehicle 1000 in response to emergencies and provide good protection for the driver and passengers.

[0059] In some embodiments of this application, the vehicle 1000 includes a windshield 310. When the first safety curtain 1 is in the deployed state, the first safety curtain 1 is in contact with the inner surface of the roof 200 and blocks at least part of the windshield 310, thereby improving the protective effect of the first safety curtain 1 on the occupants in the passenger compartment.

[0060] In some embodiments of this application, the vehicle 1000 also includes a rear windshield 320. When the second safety curtain 2 is in the deployed state, the second safety curtain 2 is in contact with the inner surface of the roof 200 and blocks at least part of the rear windshield 320, thereby improving the protective effect of the second safety curtain 2 on the occupants in the passenger compartment.

[0061] Understandably, when the roof airbag 100 fits snugly against the inner surface of the roof cover 200, it ensures the protective effect of the roof airbag 100 on the occupants. When the roof airbag 100 is deployed, it fits snugly against the roof cover 200 and is positioned between the occupants and the roof cover 200. This allows the roof airbag 100 to cushion the impact force on the occupants' heads or upper limbs, preventing injury from the impact.

[0062] Since the roof safety curtain 100 fits snugly against the roof cover 200, it forms a protective structure on the roof cover 200 facing the passenger compartment that has a good buffering effect on the impact force. The roof safety curtain 100 can buffer the impact force between the driver and passengers and the roof cover 200.

[0063] Furthermore, it can be understood that when the roof safety curtain 100 is deployed, it can shield the glass of the vehicle 1000. Specifically, the first safety curtain 1 can shield the front windshield 310, and the second safety curtain 2 can shield the rear windshield 320. Thus, the roof safety curtain 100 can shield the occupants in the passenger compartment, preventing the glass from breaking and hitting the occupants, thereby improving the protection effect for the occupants.

[0064] like Figure 1 As shown, in some embodiments of this application, the vehicle 1000 includes a roof 200, which has a storage portion 220 that is recessed upward from the side surface of the roof 200 facing the passenger compartment, and the storage portion 220 is used to store the roof safety curtain 100.

[0065] Understandably, storing the roof safety curtain airbag 100 in the storage part 220 of the roof cover 200 can maintain the appearance consistency of the roof cover 200 facing the passenger compartment, while avoiding the roof safety curtain airbag 100 being exposed and easily causing false triggering problems, thus improving the triggering reliability and accuracy of the roof safety curtain airbag 100.
