The airbag mounting structure 100 is applied to a vehicle, can be exploded into the vehicle when the vehicle collides, plays a role in buffering, buffers the collision force applied to a user when the vehicle collides, and further reduces the injury to the user as much as possible.

It can be understood that, at present, the airbag is installed at the front driving position of the instrument panel, and the airbag is usually fixed with the instrument panel through the airbag frame, and the airbag is exploded through the instrument panel during explosion. However, most of the connection between the airbag and the vehicle body is realized by adding an airbag frame on an instrument panel in a welding mode, and the airbag is connected with the airbag frame through a self bracket, so that the cost of the airbag frame is increased for the whole vehicle, and the explosion test cost is high.

Therefore, the present disclosure provides a novel airbag mounting structure 100, and this airbag mounting structure 100 is installed for the overhead, need not to set up other mounting structures, reduces the overall cost of airbag mounting structure 100, can also reduce the test cost simultaneously. The specific structure of the airbag mounting structure 100 is described below.

It is understood that the roof 200 is located on the top of the vehicle body, which is a shell of the top of the vehicle body, and the roof 300 is located inside the vehicle body and below the roof 200, with a certain distance between the roof 200 and the roof 300. The airbag mounting structure 100 is fixed to the top cover 200 and is located between the top cover 200 and the ceiling 300. Top cap 200 has certain bearing capacity, and behind airbag mounting structure 100 was fixed in top cap 200, impact force when top cap 200 can bear the gasbag and explode, and impact force when avoiding airbag mounting structure 100 to explode leads to ceiling 300 to drop, and in addition, ceiling 300 can also realize hiding of airbag mounting structure 100, avoids airbag mounting structure 100 to expose inside the vehicle, guarantees that the inside outward appearance of vehicle is pleasing to the eye.

Referring to fig. 1 and 2, in one embodiment, the airbag mounting structure 100 includes a mounting frame 110 and an airbag body 120. Is installed between the ceiling 300 and the roof 200 of the vehicle. The mounting frame 110 is fixedly installed on the top cover 200 and is close to a predetermined gap between the ceiling 300 and the front windshield. The airbag body 120 is folded and disposed in the mounting frame 110, and the explosion position of the airbag body 120 is located in the preset gap.

The mounting frame 110 is a mounting body of the airbag mounting structure 100, carries various parts of the airbag mounting structure 100 through the mounting frame 110, and fixes the mounting frame 110 to the top cover 200. The mounting frame 110 has a hollow structure in which the airbag body 120 can be accommodated. Specifically, the airbag body 120 is folded and disposed in the mounting frame 110, which can reduce the space occupied by the airbag body 120, so that the airbag mounting structure 100 can be located between the ceiling 300 and the top cover 200, facilitating the installation and arrangement of the airbag mounting structure 100.

When the vehicle collides, the airbag body 120 explodes in the installation frame 110, specifically when the airbag explodes in the installation frame 110, the airbag body 120 explodes from the preset gap between the ceiling 300 and the front windshield, so that the airbag body 120 is located in the vehicle after the explosion, a buffering effect is exerted on a user in the vehicle, the impact of collision on the user is reduced, and the safety of the user is ensured.

The airbag mounting structure 100 of the above embodiment directly fixes the airbag body 120 to the roof 200 through the mounting frame 110, and locates the airbag body 120 between the roof 200 and the ceiling 300, so that the explosion position of the airbag body 120 is located at the predetermined gap between the ceiling 300 and the front windshield, and the predetermined gap between the ceiling 300 and the front windshield can enter the inside of the vehicle when the airbag body 120 is exploded. This gasbag mounting structure 100 realizes the installation of gasbag body 120 through the installation frame 110 of self, need not to set up other mounting structure, and the cost that the effectual present gasbag of solution was installed and is led to in copilot instrument board department increases the problem, reduces gasbag mounting structure 100's overall cost, can also reduce test cost simultaneously.

Referring to fig. 1 and 2, in an embodiment, an edge of the mounting frame 110 has a plurality of fixing holes 1121 disposed at intervals, and the airbag mounting structure 100 further includes a plurality of fixing members, which pass through the fixing holes 1121 to be fixed to the top cover 200. The fixing piece is a threaded piece.

The fixing member is used to fix the airbag mounting structure 100 to the top cover 200, and specifically, the fixing member passes through the fixing hole 1121 of the edge of the mounting frame 110 to fix the mounting frame 110 to the top cover 200, thereby ensuring that the airbag mounting structure 100 is reliably fixed. Further, the fixing member is a screw member, and the screw member is fixed to the roof 200 of the vehicle after passing through the edge of the mounting frame 110, so that the airbag body 120 can be firmly connected to the vehicle body through the mounting frame 110. Thus, the impact force generated when the airbag body 120 is exploded does not cause the screw to separate from the top cover 200, thereby ensuring that the airbag mounting structure 100 is reliably fixed to the top cover 200.

The airbag mounting structure 100 of the above embodiment secures the mounting frame 110 to the top cover 200 by the fixing member which is a screw member, ensuring that the mounting frame 110 can be reliably fixed to the top cover 200. When the airbag is exploded, the impact force of the airbag does not cause the mounting frame 110 to separate from the top cover 200, so that the mounting frame 110 does not cause the ceiling 300 to fall, thereby preventing the user from being injured by the ceiling 300. Moreover, the fixing member can make the explosion position of the airbag body 120 located at the preset gap between the ceiling 300 and the front windshield, and when the airbag body 120 is exploded, the airbag body is exploded from the preset gap between the ceiling 300 and the front windshield to enter the interior of the vehicle, thereby playing a role of buffering a user in the interior of the vehicle.

In an embodiment, the mounting frame 110 includes a frame main body 111 and two fixing edges 112, the frame main body 111 partially accommodates the airbag body 120, the two fixing edges 112 are symmetrically disposed on two sides of the frame main body 111, and each fixing edge 112 has at least one fixing hole 1121.

The frame main body 111 is a main structure of the mounting frame 110 carrying the airbag body 120, the airbag body 120 is partially located in the frame main body 111, and an end of the airbag body 120 exposed out of the frame main body 111 is disposed near a preset gap between the ceiling 300 and the front windshield. Thus, when the airbag body 120 is exploded, the portion of the airbag body 120 exposed from the frame body 111 is not blocked by the frame body 111, and can be exploded through a predetermined gap between the ceiling 300 and the front windshield to enter the vehicle.

The fixing edges 112 are symmetrically disposed at both side edges of the frame body 111, and the fixing edges 112 are used for connecting the mounting frame 110 with fixing members, so that the fixing members can penetrate through the fixing edges 112 to fix the mounting frame 110 to the top cover 200. The fixing edge 112 has a fixing hole 1121 through which the fixing member passes, and after the fixing member passes through the fixing hole 1121, the mounting frame 110 can be fixed to the top cover 200, so that the mounting frame 110 is reliably fixed to the top cover 200, and further, the airbag mounting structure 100 is reliably fixed to the top cover 200, and the mounting frame 110 is prevented from being separated from the top cover 200 due to the impact of the explosion of the airbag body 120.

Optionally, the two fixing edges 112 are integral with the frame body 111. Therefore, the structural reliability of the mounting frame 110 can be ensured, the connection between the fixing edge 112 and the frame main body 111 is prevented from being broken under the action of the bursting impact force of the airbag body 120, and the mounting frame 110 is reliably fixed on the top cover 200.

Referring to fig. 1 and 2, in an embodiment, the frame main body 111 has a burst area located between the two fixing sides 112 and facing the front windshield, for bursting the airbag body 120 through the burst area.

The explosion region is an explosion space provided by the frame main body 111 for the airbag body 120. After the airbag body 120 is attached to the burst region of the frame body 111, the airbag body 120 can be exposed to the frame body 111 through the burst region. When the airbag body 120 explodes, the airbag body 120 can be exposed at the explosion area of the frame main body 111, and the frame main body 111 can be prevented from blocking the explosion of the airbag body 120, so that the airbag body 120 can be accurately exploded to play a role in buffering a user in the vehicle.

The frame body 111 and the two fixing sides 112 are configured to be open at one side, and a space corresponding to the open portion is a blasting region. After the mounting frame 110 is fixed to the roof 200 by the fixing member, the explosion region can be aligned with a predetermined gap between the ceiling 300 and the front windshield, so that the airbag body 120 in the explosion region can be exploded through the predetermined gap.

In an embodiment, the frame body 111 includes a fixed base 1111 and at least one limiting element 1112, two ends of the fixed base 1111 are respectively connected to the two fixed sides 112 and are configured to surround the blasting area, and the limiting element 1112 is disposed on the fixed base 1111 and extends to the blasting area.

The fixing base 1111 is used to realize the installation and fixation of the airbag body 120, so that the airbag body 120 is reliably fixed in the installation frame 110. The fixing base 1111 is provided with fixing edges 112 at both sides thereof, and forms a concave structure, the inner space of the concave structure is a blasting area, and the airbag body 120 is installed at the inner side of the concave structure. The limiting part 1112 is disposed on the fixing base 1111 and extends toward the blasting area, and the limiting part 1112 is configured to limit the position of the airbag body 120, so as to prevent the airbag body 120 from moving toward the outer side of the installation frame 110, ensure the position of the airbag body 120 in the installation frame 110 is fixed, and further ensure that the airbag body 120 can be blasted accurately.

Optionally, the position-limiting element 1112 is integrated with the fixing base 1111. This ensures the structural reliability of the frame body 111, and prevents the frame body 111 from being damaged by impact.

Illustratively, as shown in fig. 1, each fixing edge 112 has two fixing holes 1121, the two fixing holes 1121 are spaced apart, and the mounting frame 110 can be reliably fixed to the top cover 200 through the four fixing holes 1121 on the two fixing edges 112. Of course, in other embodiments of the present disclosure, only one fixing hole 1121 may be provided for each fixing edge 112, or three or more fixing holes 1121 may be provided for each fixing edge 112.

In an embodiment, the distance between the fixing hole 1121 and the longitudinal edge of the fixing edge 112 ranges from 60mm to 70 mm. That is, the distance between the fixing hole 1121 and the end of the fixing edge 112 along the length direction of the fixing edge 112 is in the range of 60mm to 70mm, so that the structural strength of the fixing edge 112 can be ensured, and the mounting frame 110 can be reliably fixed by the engagement of the fixing member with the fixing hole 1121.

When the number of the fixing holes 1121 is plural, the distance between the fixing hole 1121 of the fixing edge 112 near one end of the fixing edge 112 and the corresponding end of the fixing edge 112 is in the range of 60mm to 70 mm. Illustratively, the distance from the upper fixing hole 1121 to the upper end of the fixing side 112 is 60mm to 70mm, and the distance from the lower fixing hole 1121 to the lower end of the fixing side 112 is 60mm to 70mm, based on the square shape shown in fig. 1.

In an embodiment, when there are a plurality of fixing holes 1121 on the same fixing edge 112, the distance between two adjacent fixing holes 1121 ranges from 50mm to 60 mm. That is, the fixing holes 1121 are spaced apart from each other, and a distance between two adjacent fixing holes 1121 is in a range of 50mm to 60 mm. Illustratively, as shown in fig. 1, two fixing holes 1121 are spaced apart along the length direction of the fixing edge 112, and the distance between the two fixing holes 1121 is 50mm to 60 mm.

That is, mounting portions to which fixing members are connected are provided in both top cover 200 and ceiling 300, one end of the fixing member passes through fixing hole 1121 to fix mounting frame 110 to top cover 200, and the other end of the fixing member is fixed to ceiling 300. It can be understood that the roof 300 is usually connected with the vehicle body in a clamping manner, and after the roof 300 is connected by the fixing member, the roof 200 can be indirectly fixedly connected with the roof 300, so that the roof 300 is ensured to be fixed and reliable.

In this way, the ceiling 300 can be fixed to the top cover 200 by the fixing members, and the hard connection between the ceiling 300 and the top cover 200 can be achieved. When the ceiling 300 is impacted by the impact force generated by the air bag body 120 during the explosion, the ceiling 300 does not fall off because the ceiling 300 is connected with the fixing members and fixed to the top cover 200, so that the danger of the ceiling 300 collapsing is reduced, and further, the damage to the user caused by the collapse of the ceiling 300 is avoided.

Referring to fig. 1 and 2, in an embodiment, the airbag mounting structure 100 further includes a plurality of covers disposed at ends of the fixing members extending out of the ceiling 300. After the fixing piece is connected with the ceiling 300, the end part of the fixing piece can be exposed out of the ceiling 300, the appearance inside the vehicle is affected, therefore, the end part of the fixing piece is covered, the fixing piece is arranged through the blocking cover, the exposure of the fixing piece is avoided, and the appearance inside the vehicle is attractive.

When the airbag mounting structure 100 is installed, a first mounting hole corresponding to the fixing hole 1121 is opened at a position corresponding to the top cover 200, before the ceiling 300 is installed, the airbag body 120 is folded and disposed in the mounting frame 110, the mounting frame 110 is fixed to the top cover 200 by a fixing member which is a screw member, and the fixing member is fastened by a wrench, thereby ensuring that the fixing member reliably fixes the mounting frame 110 to the top cover 200. After the mounting frame 110 is mounted, the ceiling 300 is fixed to the vehicle body, and the other end of the fixing member is connected to the ceiling 300.

Referring to fig. 1 and 2, in the airbag mounting structure 100 of the present disclosure, the mounting frame 110 is used to accommodate the airbag body 120 and mount the airbag body 120 in an overhead manner, so that other mounting structures are not required, the mounting cost is reduced, and the explosion test cost can also be reduced. Moreover, the installation frame 110 is fixedly connected with the top cover 200 and the ceiling 300 through the fixing piece which is a threaded piece, so that the air bag installation structure 100 is ensured to be reliably fixed, the risk that the ceiling 300 collapses due to the fact that the air bag installation structure 100 is separated from the top cover 200 is avoided, and passengers are prevented from being injured by falling of the ceiling 300.

Referring to fig. 1 and 2, the present disclosure also provides a vehicle including a vehicle body, a roof 300, and the airbag mounting structure 100 described in the above embodiment. The vehicle body is provided with a top cover 200 and a front windshield, the roof 300 is installed in the vehicle body and is positioned below the top cover 200, a preset gap exists between the top cover 200 and the top of the front windshield, and the airbag installation structure 100 is positioned between the roof 300 and the top cover 200 and is exploded from the preset gap.

Specifically, one end of the fixing member is fitted into the first fitting hole through the fixing hole 1121 of the mounting frame 110, and the other end of the fixing member is fitted into the second fixing hole 1121, and the front sunshade is fixed to the ceiling 300. And the end part of the fixing piece can be shielded through the assistant driving sun visor without using the blocking cap in the embodiment.

Of course, the sun visor for the front passenger side is eliminated from the right side vehicle, and at this time, a hole for installing the fixing member needs to be formed in the ceiling 300. Specifically, the ceiling 300 has a third mounting hole through which the fixing member protrudes.

That is, when the vehicle does not have a passenger visor, a third mounting hole is formed in the ceiling 300, one end of the fixing member is fixed to the first mounting hole of the top cover 200 through the fixing hole 1121, and the other end of the fixing member is mounted to the second mounting hole of the ceiling 300, so that the fixing member is connected to the ceiling 300. Moreover, the end part of the fixed part is covered with a blocking cap to ensure the beautiful appearance of the interior of the vehicle.

Referring to fig. 1 to 3, in one embodiment, the canopy 300 has a weakened area 310, the weakened area 310 is adjacent to the front windshield and corresponds to the airbag mounting structure 100, and the weakened area 310 has a structural strength less than that of the rest of the canopy 300.

The strength of the weakened region 310 is small compared to the remaining region of the ceiling 300, and the weakened region 310 does not affect the explosion of the airbag body 120. Specifically, a portion of the ceiling 300 near the front windshield is a weakened area 310, and the weakened area 310 corresponds to a burst area of the airbag mounting structure 100. When the airbag body 120 is exploded, the airbag body 120 may burst the weakened area 310 of the ceiling 300, and then enter the interior of the vehicle through the weakened area 310 and a predetermined gap between the ceiling 300 and the front windshield.

That is to say, after the weakened area 310 is provided, when the airbag body 120 is exploded, after the weakened area 310 is exploded, the distance between the ceiling 300 and the front windshield, which is the preset gap, is increased, and the airbag body 120 easily enters the vehicle, so that the airbag body 120 can timely buffer the user and reduce the impact on the user. If the weakening area 310 is not provided, the strength of the ceiling 300 is relatively strong, and when the airbag is exploded from a preset gap between the ceiling 300 and the front windshield and enters the vehicle, the explosion time of the airbag body 120 is increased, the speed of the airbag body 120 entering the vehicle is affected, and the buffering effect of the airbag body 120 is further affected.

The weakened area 310 extends to the edge of the ceiling 300, i.e. the weakened area 310 forms a concave-like structure, and the contour thereof is enclosed by the weakened area 310, so that the impact force of the airbag can cause the weakened area 310 to burst at the edge when the airbag bursts, and the weakened area 310 is separated from the ceiling 300.

In one embodiment, the weakened region 310 has a first contour 311, the first contour 311 passes through two fixing edges 112 of the airbag mounting structure 100, and the first contour 311 surrounds one of the fixing holes 1121 of the fixing edges 112 and is close to the other fixing hole 1121.

The first contour 311 is located in the ceiling 300 and extends in the direction of the line connecting the two fixed sides 112 on the mounting frame 110. The first contour 311 is located on a side of the fixing hole 1121 away from the front windshield, and has a certain distance from the fixing hole 1121. In this way, an exact corresponding weakening zone 310 of the airbag body 120 in the mounting frame 110 can be ensured. Illustratively, as shown in fig. 3, the first contour 311 is located between the upper and lower fixing holes 1121 and is disposed near the lower fixing hole 1121.

In an embodiment, the weakened region 310 further has a second contour line 312 and a third contour line 313, and the second contour line 312 and the third contour line 313 are respectively located at two sides of the first contour line 311 and extend toward the front windshield.

The first contour 311, the second contour 312, and the third contour 313 enclose a weakened region 310. Optionally, the second contour 312 is perpendicular to or at an angle to the first contour 311. The third contour line 313 is perpendicular to or at an angle to the first contour line 311. Optionally, the third contour line 313 is arranged parallel or inclined to the second contour line 312.

The first contour line 311, the second contour line 312, and the third contour line 313 may be provided to correspond to the airbag main body 120 after enclosing the weakened region 310, and may be exploded into the vehicle through the weakened region 310 and a predetermined gap between the ceiling 300 and the front windshield when the airbag main body 120 is exploded.

In an embodiment, the distance between the second contour line 312 and the corresponding fixed edge 112 is greater than or equal to 20mm, and the distance between the third contour line 313 and the corresponding fixed edge 112 is greater than or equal to 20 mm. This enables the range of the weakened region 310 to be large enough to cover the explosion region of the airbag body 120, thereby avoiding blocking the explosion of the airbag body 120 and ensuring the explosion effect of the airbag body 120.

The vehicle adopts the overhead installation airbag mounting structure 100, so that the explosion test cost and the production cost can be reduced, meanwhile, the weakened area 310 is arranged on the ceiling 300, so that the airbag body 120 can enter the interior of the vehicle through the weakened area 310, and the efficiency of the airbag body 120 entering the interior of the vehicle after being exploded is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
