[0031] In some possible implementations, the characteristic guide bracket 3 is used as follows: Figure 2 and Figure 4 See the structure shown. Figure 2 and Figure 4 The lower part of the guide bracket 3 is connected to the inner side of the door panel inner sheet metal 5 through the first connecting member 31. The first connecting member 31 is located below the airbag generator 2. The guide bracket 3 extends obliquely from bottom to top toward the central axis side of the vehicle body.

[0032] In this embodiment, when installing the guide bracket 3, the guide bracket 3 is connected to the inner side of the sheet metal 5 in the door panel (that is, the side close to the center axis of the vehicle body) through the first connecting member 31. The first connecting member 31 passes through the guide bracket 3 and the sheet metal 5 in the door panel. Threaded connecting members such as bolts and screws can be used, and connecting members such as pins and rivets can also be used.

[0033] Specifically, a plurality of first connecting members 31 are provided, and the plurality of first connecting members 31 are distributed near the lower edge of the guide bracket 3. The first connecting member 31 is located below the airbag generator 2, and the guide bracket 3 extends upward toward the inner side of the vehicle body and is located on the side of the airbag generator 2 and the airbag airbag 1 close to the center axis of the vehicle body.

[0034] At the same time, the portion of the door panel sheet metal 5 adjacent to the airbag 1 is obliquely extended toward the outside of the vehicle body, and a space for accommodating the airbag 1 and the airbag generator 2 is formed between the door panel sheet metal 5 and the guide bracket 3, which is convenient for the layout of the structure. At the same time, the guide bracket 3 guides the explosion direction of the airbag 1, so that the passenger's head can be effectively protected after the airbag 1 explodes.

[0035] In some embodiments, the above-mentioned characteristic guide bracket 3 can be used as follows Figure 2 and Figure 5 See the structure shown. Figure 2 and Figure 5 A reinforcing ridge 32 is provided on the plate surface of the guide bracket 3 , and the reinforcing ridge 32 is protruded toward a side away from the airbag generator 2 .

[0036] In this embodiment, the reinforcing ridges 32 arranged on the guide bracket 3 can effectively strengthen the structural strength of the guide bracket 3 itself, and effectively improve its structural strength without increasing the structural weight of the guide bracket 3, thereby ensuring the guiding role of the airbag 1 during the explosion process, so that the airbag 1 can effectively protect the passenger's head after the explosion, thereby achieving good safety performance.

[0037] Specifically, the reinforcing ridges 32 may be in a form extending along the front-rear direction of the vehicle body, or in a form extending up and down, both of which may have a structural reinforcement effect.

[0038] In some possible implementations, the above-mentioned characteristic airbag 1 and airbag inflator 2 are used as follows: Figure 2 and Figure 4 See the structure shown. Figure 2 and Figure 4 The airbag 1 and the airbag generator 2 are integrally formed, the airbag 1 extends in the front-rear direction, and the airbag generator 2 is connected to the middle of the extending direction of the airbag 1. The airbag 1 is connected above the airbag generator 2, and the bottom of the airbag 1 has a connecting portion integrally formed with the airbag generator 2. The airbag 1 and the airbag generator 2 are internally interconnected, and the gas generated by the airbag generator 2 can be instantly filled into the airbag 1, so that the airbag 1 forms an explosion effect and explodes from the trim panel 6 on the door interior panel, thereby effectively protecting the passenger's head.

[0039] Specifically, the airbag 1 extends a certain length in the front-to-back direction, which is convenient for effectively covering the inner space of the door, helping to expand the coverage of the airbag 1 when it explodes, and improving the protection of passengers. The airbag generator 2 is located in the middle of the extension direction of the airbag 1, which can increase the inflation speed of the gas, ensure that all parts of the airbag 1 can explode synchronously, and form effective protection for passengers.

[0040] In some embodiments, the above-mentioned characteristic airbag 1 and airbag inflator 2 can be used as follows: Figure 4 See the structure shown. Figure 4 A connecting plate 4 is respectively provided at the lower part of the airbag 1 and the airbag generator 2, and the connecting plate 4 is connected to the inner sheet metal 5 of the door panel through a second connecting member.

[0041] In this embodiment, the airbag 1 and the airbag generator 2 are respectively connected to the sheet metal 5 inside the door panel through a connecting plate 4. In order to avoid affecting the upper space of the airbag 1, the connecting plate 4 is arranged at the lower position of the airbag 1. Similarly, the connecting plate 4 of the airbag generator 2 is also arranged at its lower position, so as to facilitate the support of the upper airbag 1 or airbag generator 2 with the help of the connecting plate 4.

[0042] Specifically, the connecting plate 4 is connected to the inner sheet metal 5 of the door panel through a second connecting member. The second connecting member can be a bolt, a screw or a pin, which is not only convenient for disassembly and assembly but also can ensure the reliability of the connection.

[0043] In some embodiments, the above-mentioned characteristic connecting plate 4 can be used as follows Figure 4 See the structure shown. Figure 4 A plurality of connecting plates 4 are provided on the airbag 1 and the airbag generator 2, respectively, and all the connecting plates 4 on the airbag 1 and the airbag generator 2 are arranged at intervals along the front-to-back direction. By providing a plurality of connecting plates 4, the connection points between the airbag 1 or the airbag generator 2 and the sheet metal 5 in the door panel can be increased, thereby ensuring the reliability of the installation of the airbag 1 and the airbag generator 2.

[0044] Specifically, the connecting plate 4 may adopt a rectangular plate structure, and the airbag 1 and the airbag generator 2 may be installed and fixed to the inner side of the door panel inner sheet metal 5 by a second connecting member penetrating the connecting plate 4 and the door panel inner sheet metal 5 .

[0045] In some possible implementations, the above-mentioned characteristic airbag 1 is used as follows Figure 2 See the structure shown. Figure 2 A gap a is provided between the airbag 1 and the inner top wall of the door interior trim panel 6, and a is 3 mm-10 mm.

[0046] In this embodiment, the setting of gap a can leave space between the top of the airbag airbag 1 and the inner top wall of the door interior trim panel 6, thereby preventing the vehicle from vibrating during driving and causing friction and wear between the surface of the airbag airbag 1 and the inner top wall of the door interior trim panel 6.

[0047] The above-mentioned gap a is selected in the range of 3mm to 10mm, which can not only achieve effective accommodation of the airbag 1, but also shorten the distance traveled by the airbag 1 during the explosion process, so that the airbag 1 can explode in time to the position covering the upper outside of the passenger, thereby improving the safety of the airbag use.

[0048] The utility model also provides a vehicle door structure, characterized in that it includes a door panel inner sheet metal 5, a door interior trim panel upper panel 6 and a side airbag mounting structure, a first weakening line 51 located on the side of the airbag airbag 1 is provided on the side wall of the door interior trim panel 6, and the first weakening line 51 extends along the front-to-back direction and is arranged below the upper edge of the guide bracket 3; when the airbag airbag 1 explodes, the door interior trim panel 6 can be cracked at the first weakening line 51 under the impact of the airbag airbag 1 to expose the airbag airbag 1.

[0049] In the present embodiment, a first weakening line 51 is provided on the side wall of the upper trim panel 6 of the door interior trim. The first weakening line 51 is formed by reducing the thickness of the plate in the corresponding area. The first weakening line 51 extends in the front-to-back direction to form a weakened area on the side of the trim panel 6 on the door interior trim, so that the airbag 1 can impact the trim panel 6 on the door interior trim during the explosion process and form a crack at the first weakening line 51, so that the airbag 1 can expand and explode to the outside of the trim panel 6 on the door interior trim, thereby forming effective protection for the passenger's head and ensuring the personal safety of the passenger.

[0050] On the basis of the above structure, the above characteristic interior trim panel adopts the following Figure 2 See the structure shown. Figure 2 A second weakening line 52 located above the airbag 1 is provided on the top wall of the upper trim panel 6 of the door interior trim, and the second weakening line 52 extends in the front-to-back direction; when the airbag 1 explodes, the upper trim panel 6 of the door interior trim can be cracked at the first weakening line 51 and the second weakening line 52 respectively under the impact of the airbag 1, so as to form a hole between the first weakening line 51 and the second weakening line 52 for exposing the airbag 1.

[0051] In this embodiment, a second weakening line 52 is provided to effectively cooperate with the first weakening line 51, and weakened areas are respectively formed on the top and sides of the trim panel 6 on the door interior trim, so that the two can crack at the same time when the airbag 1 explodes, and a hole area is formed between the first weakening line 51 and the second weakening line 52 for the airbag 1 to be exposed when it explodes, thereby achieving effective protection of the passenger's head and body parts by the airbag 1, thereby improving the safety of the vehicle.

[0052] The vehicle door structure provided in the embodiment of the present application utilizes the space between the sheet metal 5 inside the door panel and the trim panel 6 on the door interior to install the airbag 1, the airbag generator 2 and the guide bracket 3, so that the airbag 1 can explode from above the trim panel 6 on the door interior along the direction of the guide bracket 3, thereby protecting the occupants in the vehicle from the side, especially protecting the heads of the occupants, improving the safety factor of the occupants and enhancing the competitiveness of the product.

[0053] Based on the same inventive concept, the embodiment of the present application also provides a vehicle. The vehicle uses a guide bracket 3 to guide the airbag 1 to explode from the door interior panel trim 6 to the inner side and upper side of the vehicle body, thereby protecting the driver and passengers in the vehicle from the side, especially protecting the driver and passengers' heads, thereby improving the safety factor of the driver and passengers and enhancing the competitiveness of the product.
