Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] With the development of technology and the improvement of people's living standards, vehicles have become an indispensable means of transportation. Vehicles are equipped with air curtain guide panels. In the event of a gas explosion in the air curtain, the guide panels can guide the airbags of the safety air curtain to deploy effectively, preventing the airbags from being scratched and leaking by the upper edge of the pillar trim panels, thus effectively protecting passengers.

[0003] In existing technologies, the current air curtain guide plate structure consists of an inner side panel and an air curtain guide plate. The guide surface of the guide plate is located below the safety air curtain. When the air curtain explodes, it inflates and moves diagonally downwards along the direction of the guide plate. The overlap between the roof edge and the pillar trim is located on the upper side of the pillar trim, while the lower edge of the air curtain guide plate is above the roof. The air curtain is pushed out of the roof along the direction of the guide plate and does not contact the upper edge of the pillar trim. This avoids scratches from the air curtain, but it prevents the placement of other components between the safety air curtain and the vehicle body. In vehicles with rear air conditioning, the rear air duct needs to be positioned between the safety air curtain and the vehicle body for the safety air curtain to deploy properly. With this structure, in vehicles with rear air conditioning, the safety air curtain cannot extend to the rear air duct area, thus failing to effectively protect the safety of rear occupants.

[0042] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0043] The following is for reference. Figures 1-15 According to an embodiment of the present invention, a vehicle 100 is described, wherein the safety curtain airbag 40 of the vehicle 100 can extend to the rear air duct 20 of the air conditioner.

[0044] Combination Figures 1-15 As shown, the vehicle 100 according to the present invention may mainly include: a body 10, a rear air conditioning duct 20, an air curtain guide plate 30, and a safety air curtain 40. The body 10 includes a C-pillar inner panel 101 and a D-pillar inner panel 102, with the D-pillar inner panel 102 connected to the rear side of the C-pillar inner panel 101. This not only ensures the structural strength and integrity of the vehicle 100, but also supports the roof while providing installation positions for other components. Furthermore, it isolates the interior space from the exterior space, improving the comfort of the vehicle 100.

[0045] The rear air conditioning duct 20 is at least partially located between the inner panel 101 of the C-pillar and the inner panel 102 of the D-pillar, so that the treated air can be evenly delivered to the rear space of the vehicle 100, making the temperature inside the vehicle more uniform and further providing a comfortable riding environment for rear passengers.

[0046] The air curtain guide plate 30 extends in the front-to-back direction and is located on the side of the rear air conditioning duct 20 away from the inner C-pillar panel 101 and / or the inner D-pillar panel 102 in the left-to-right direction. The front end of the air curtain guide plate 30 is connected to the inner C-pillar panel 101, and the rear end of the air curtain guide plate 30 is connected to the inner D-pillar panel 102. This not only provides an installation position for the air curtain guide plate 30, allowing it to extend to the rear air conditioning duct 20 to ensure the coverage area of ​​the safety air curtain 40 after deployment, but also guides the deployment of the safety air curtain 40, thus allowing the deployment direction and path of the safety air curtain 40 to be preset, further improving the structural reliability of the vehicle 100.

[0047] The safety curtain airbag 40 extends in the front-rear direction. At least part of the safety curtain airbag 40 is located on the side of the airbag guide plate 30 away from the rear air duct 20 in the left-right direction. The safety curtain airbag 40 is connected to the airbag guide plate 30. The airbag guide plate 30 can guide the safety curtain airbag 40 to deploy quickly and accurately according to a preset direction and trajectory, and ensure that the safety curtain airbag 40 can cover the rearmost position of the vehicle body 10. In this way, not only can the force be transferred to the safety curtain airbag 40 through the airbag guide plate 30, thereby helping the safety curtain airbag 40 to absorb and disperse part of the force, but it can also optimize the deployment path of the safety curtain airbag 40 and keep the safety curtain airbag 40 in a stable shape and position during deployment. This can avoid the deformation or displacement of the safety curtain airbag 40 due to airflow or other factors, and enhance the stability of the safety curtain airbag 40. In addition, through the guiding effect of the airbag guide plate 30, the safety curtain airbag 40 can cover the rear space of the vehicle 100 after deployment, thereby effectively protecting the safety of the occupants inside the vehicle.

[0048] Furthermore, when vehicle 100 is involved in a collision, the safety curtain 40 deploys along the predetermined path of the curtain guide plate 30 to form a protective barrier, and the deployment range effectively covers the rearmost position of vehicle 100. This not only absorbs and disperses some of the collision energy, playing a buffering role, but also provides protection for critical parts such as the head, neck and shoulders of the occupants, thereby reducing the impact and injury caused to the occupants by the collision. In addition, it can also help maintain the relative position of the occupants in the vehicle, reducing additional injuries caused by secondary collisions with other parts of the vehicle.

[0049] Therefore, by setting an air curtain guide plate 30 on the side of the rear air duct 20 away from the inner C-pillar panel 101 and / or the inner D-pillar panel 102 in the left and right direction, and connecting the air curtain guide plate 30 to the safety air curtain 40, the inner C-pillar panel 101 and the inner D-pillar panel 102, the air curtain guide plate 30 can provide the safety air curtain 40 with arrangement space and guidance function, and can extend the safety air curtain 40 to the rear of the vehicle body 10, thereby effectively protecting the safety of the rear occupants of the vehicle 100.

[0050] In some examples of the present invention, it should be noted that during installation, the air conditioning rear duct 20 should be installed first, followed by the air curtain guide plate 30, and finally the safety air curtain 40. This can ensure the accuracy of the installation and avoid unnecessary installation problems.

[0051] In some examples of the present invention, the rear side of vehicle 100 may be the third row of seats, and the specific position is determined according to the vehicle model.

[0052] In some examples of the present invention, the safety curtain 40 can be made of a material with high strength, high temperature resistance, tear resistance, etc. The front and rear sides of the safety curtain 40 can be made of different materials depending on the stress conditions. The material on the rear side near the inflation position can be harder than the material on the front side away from the inflation position. Furthermore, the safety curtain 40 can be a single-layer or multi-layer structure, wherein the number of layers in the multi-layer structure is greater than or equal to 2. When the safety curtain 40 is a multi-layer structure, different layers can be made of different materials. The innermost layer can be made of a tear-resistant material, and the outermost layer can be made of an elastic material with low hardness and low friction. This can improve the structural strength and protective performance of the safety curtain 40 and prevent the safety curtain 40 from breaking and leaking air, thereby causing the protective function to fail.

[0053] In some examples of the present invention, the cross-section of the safety curtain 40 in the left and right directions after it is deployed can be circular, elliptical, rectangular or square with rounded corners, etc.

[0054] Combination Figure 7 , Figure 9 and Figure 10 As shown, the air curtain guide plate 30 is provided with a first through hole 301 and a second through hole 302, the C-pillar inner plate 101 is provided with a third through hole 103, and the D-pillar inner plate 102 is provided with a fourth through hole 104. The first through hole 301 and the third through hole 103 correspond to each other and are connected and fixed by a first fastener 105, and the second through hole 302 and the fourth through hole 104 correspond to each other and are connected and fixed by a second fastener 106. Specifically, the air curtain guide plate 30 is provided with a first through hole 301, and the C-pillar inner panel 101 is provided with a third through hole 103. The first through hole 301 and the third through hole 103 correspond to each other in structure and position. The first fastener 105 passes through the first through hole 301 and the third through hole 103 in sequence, thereby connecting and fixing the air curtain guide plate 30 to the C-pillar inner panel 101. This not only makes the connection between the air curtain guide plate 30 and the C-pillar inner panel 101 simple and direct, but also ensures the stability and reliability of the connection between the air curtain guide plate 30 and the C-pillar inner panel 101.

[0055] Furthermore, the air curtain guide plate 30 is provided with a second through hole 302, and the inner plate 102 of the D-pillar is provided with a fourth through hole 104. The second through hole 302 and the fourth through hole 104 correspond in structure and position. The second fastener 106 passes through the second through hole 302 and the fourth through hole 104 in sequence, thereby connecting and fixing the air curtain guide plate 30 to the inner plate 102 of the D-pillar. This not only makes the connection between the air curtain guide plate 30 and the inner plate 102 of the D-pillar simple and direct, but also further improves the stability of the air curtain guide plate 30, making the air curtain guide plate 30 less prone to deformation or breakage.

[0056] With this configuration, the third perforation 103 and the fourth perforation 104 can provide mounting points for the air curtain guide plate 30. Then, through the cooperation of the first fastener 105 and the second fastener 106, both ends of the air curtain guide plate 30 are fixed. One end is installed on the inner panel 101 of the C-pillar, and the other end is installed on the inner panel 102 of the D-pillar. This not only provides stable support for the air curtain guide plate 30, giving it a certain structural strength, but also facilitates the installation and disassembly of the air curtain guide plate 30, thereby facilitating subsequent maintenance and replacement of the air curtain guide plate 30.

[0057] In some examples of the present invention, the first through hole 301, the second through hole 302, the third through hole 103, and the fourth through hole 104 can be threaded holes, and the first fastener 105 and the second fastener 106 can be screws.

[0058] Combination Figure 4 , Figure 10 and Figure 11 As shown, the air curtain guide plate 30 is provided with a fifth through hole 303 and a sixth through hole 304, and the safety air curtain 40 is provided with a seventh through hole 401 and an eighth through hole 402. The fifth through hole 303 and the seventh through hole 401 correspond to each other and are connected and fixed by a third fastener 403, and the sixth through hole 304 and the eighth through hole 402 correspond to each other and are connected and fixed by a fourth fastener 404. Specifically, the air curtain guide plate 30 is provided with a fifth through hole 303 and a sixth through hole 304, and the safety air curtain 40 is provided with a seventh through hole 401 and an eighth through hole 402. The fifth through hole 303 and the seventh through hole 401 correspond in structure and position, and the sixth through hole 304 and the eighth through hole 402 correspond in structure and position. The seventh through hole 401 and the fifth through hole 303 are sequentially passed through by a third fastener 403, and the eighth through hole 402 and the sixth through hole 304 are sequentially passed through by a fourth fastener 404, thereby connecting the safety air curtain 40 to the air curtain guide plate 30. This not only makes the connection between the air curtain guide plate 30 and the safety air curtain 40 simple, direct, stable and reliable, but also facilitates the installation and disassembly of the safety air curtain 40, thus facilitating the subsequent maintenance and replacement of the safety air curtain 40.

[0059] In some examples of the present invention, the fifth through hole 303, the sixth through hole 304, the seventh through hole 401, and the eighth through hole 402 can be threaded holes, and the third fastener 403 and the fourth fastener 404 can be screws.

[0060] Combination Figure 4 , Figure 9 , Figure 10 and Figure 14As shown, the distance between the first perforation 301 and the second perforation 302 is L1, and the distance between the fifth perforation 303 and the sixth perforation 304 is L2. L1 and L2 satisfy the relationship: L1-L2≥3mm. Specifically, by setting a certain distance between the first perforation 301 and the second perforation 302, and between the fifth perforation 303 and the sixth perforation 304, and ensuring that the distance between the first perforation 301 and the second perforation 302 is greater than the distance between the fifth perforation 303 and the sixth perforation 304, with the difference between the two distances not less than 3mm, the connection points of the air curtain guide plate 30 are spaced apart from each other. This not only avoids stress concentration at the perforation positions of the air curtain guide plate 30 and prevents breakage or deformation at the connection points of the air curtain guide plate 30, but also ensures the rationality and stability of the structure of the air curtain guide plate 30. In addition, it can also separate the installation points of the air curtain guide plate 30 and the safety air curtain 40, avoiding interference between the air curtain guide plate 30 and the safety air curtain 40, and facilitating the installation and disassembly of the air curtain guide plate 30 and the safety air curtain 40, thereby reducing the difficulty of processing, installation, and disassembly.

[0061] Combination Figure 7 , Figure 8 , Figure 9 and Figure 14 As shown, the distance between the first perforation 301 and the second perforation 302 is L1, and the distance between the fifth perforation 303 and the sixth perforation 304 is L2. L1 and L2 satisfy the relationship: L1≤L2. Mounting bosses 107 are provided on both the inner panel 101 of the C-pillar and the inner panel 102 of the D-pillar. The mounting bosses 107 protrude towards the air curtain guide plate 30 in the left and right directions and fit against the air curtain guide plate 30. The third perforation 103 is provided on the mounting boss 107 of the inner panel 101 of the C-pillar, and the fourth perforation 104 is provided on the mounting boss 107 of the inner panel 102 of the D-pillar. Specifically, by setting a certain distance between the first perforation 301 and the second perforation 302 and between the fifth perforation 303 and the sixth perforation 304, and making the distance between the first perforation 301 and the second perforation 302 less than or equal to the distance between the fifth perforation 303 and the sixth perforation 304, stress concentration at the perforation position of the air curtain guide plate 30 can be prevented, and the connection of the air curtain guide plate 30 can be prevented from breaking or deforming. It can also ensure the stability and reliability of the overall structure.

[0062] Furthermore, when the distance between the first perforation 301 and the second perforation 302 is equal to the distance between the fifth perforation 303 and the sixth perforation 304, the first fastener 105 and the third fastener 403 can be combined into one fastener, and the second fastener 106 and the fourth fastener 404 can be combined into one fastener. By sequentially inserting the corresponding perforations through the fasteners, the safety curtain 40, the air curtain guide plate 30 and the C-pillar inner panel 101 or the D-pillar inner panel 102 can be directly connected and fixed. This not only ensures the stability and reliability of the overall structure, but also reduces manufacturing costs.

[0063] Furthermore, when the mounting surface of the vehicle body 10 is no larger than the mounting surface of the air curtain guide plate 30 by no more than 3mm, mounting bosses 107 must be provided on both the inner C-pillar panel 101 and the inner D-pillar panel 102 of the vehicle body 10. The mounting bosses 107 protrude towards the air curtain guide plate 30 in the left-right direction and fit against the air curtain guide plate 30. This not only provides a precise installation position for the air curtain guide plate 30, but also facilitates the installation and removal of the air curtain guide plate 30. In addition, the mounting bosses 107 can also play a supporting role, which can improve the reliability and stability of the connection between the air curtain guide plate 30 and the inner C-pillar panel 101 and the inner D-pillar panel 102, and can avoid interference between the two mounting surfaces due to manufacturing errors or other reasons.

[0064] In addition, a third through hole 103 is provided on the mounting boss 107 of the C-pillar inner panel 101, and a fourth through hole 104 is provided on the mounting boss 107 of the D-pillar inner panel 102. By sequentially passing fasteners through the first through hole 301 and the third through hole 103, the second through hole 302 and the fourth through hole 104, the air curtain guide plate 30 is connected and fixed to the C-pillar inner panel 101 and the D-pillar inner panel 102. This can improve the strength and stability of the connection between the air curtain guide plate 30 and the C-pillar inner panel 101 and the air curtain guide plate 30 and the D-pillar inner panel 102. Moreover, the protruding design of the mounting boss 107 can also absorb and disperse some of the force, which can prevent the installation point from breaking or deforming due to stress concentration, thereby improving the reliability and stability of the structure.

[0065] Combination Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the air curtain guide plate 30 is provided with a first positioning part, and the safety air curtain 40 is provided with a second positioning part. One of the first positioning part and the second positioning part is a positioning groove 305, and the other is a positioning hook 405. The positioning hook 405 extends into the positioning groove 305 and is engaged with the edge of the positioning groove 305 for positioning. Specifically, by providing a positioning groove 305 on one of the air curtain guide plate 30 and the safety air curtain 40, and a positioning hook 405 on the other, so that the positioning hook 405 extends into the positioning groove 305 and is engaged with the edge of the positioning groove 305 for positioning, this not only prevents the safety air curtain 40 from falling off and ensures the effectiveness of the connection between the air curtain guide plate 30 and the safety air curtain 40, but also facilitates the installation and disassembly of the safety air curtain 40, simplifies the processing flow, improves processing efficiency, and reduces production costs.

[0066] Furthermore, during assembly, the positioning hook 405 is first inserted into the positioning groove 305 to pre-attach it, and then the screws are installed for further fixation. This can further strengthen the connection between the air curtain guide plate 30 and the safety air curtain 40, effectively prevent the safety air curtain 40 from shifting or loosening, and further improve the stability and reliability of the connection between the air curtain guide plate 30 and the safety air curtain 40.

[0067] In some examples of the present invention, the positioning groove 305 can be designed as 3×10mm, and the positioning hook 405 can be designed as 1×8.5mm. After pre-hanging, the end of the positioning groove 305 should extend 8mm beyond the slot surface to leave enough snap-fit ​​gap for easy matching. The snap-fit ​​depth of the positioning hook 405 can be 4mm to provide sufficient snap-fit ​​depth so that the positioning hook 405 is not easy to fall off. The snap-fit ​​joint width can be 4mm to give the snap-fit ​​structure sufficient rigidity.

[0068] Combination Figure 4 , Figure 7 and Figure 9 As shown, the portion of the rear air duct 20 corresponding to the air curtain guide plate 30 is provided with a clearance groove 50, which avoids the air curtain guide plate 30. Specifically, by placing the air curtain guide plate 30 within the clearance groove 50 reserved in the rear air duct 20, sufficient installation space is provided for the air curtain guide plate 30, reducing the difficulty of layout. This also prevents unnecessary increase in the volume of the vehicle body 10. Furthermore, it can improve the utilization rate of the space in the vehicle body 100, making the structure of the vehicle 100 more compact, thereby improving the stability and reliability of the vehicle 100 structure.

[0069] Furthermore, the setting of the clearance groove 50 allows the air curtain guide plate 30 and the safety air curtain 40 to be arranged in a more suitable position, which can effectively improve the protection and effectiveness of the safety air curtain 40 for passengers.

[0070] Combination Figure 4, Figure 7 , Figure 10 and Figure 14 As shown, the air curtain guide plate 30 is provided with a guide groove, which is open in the left-right direction toward the side away from the inner C-pillar panel 101 and the inner D-pillar panel 102. The safety air curtain 40 is at least partially disposed in the guide groove. Specifically, by at least partially disposing the safety air curtain 40 in the guide groove of the air curtain guide plate 30, and by having the guide groove open in the left-right direction toward the side away from the inner C-pillar panel 101 and the inner D-pillar panel 102, this not only provides a certain guiding effect for the deployment of the safety air curtain 40, ensuring that the safety air curtain 40 can smoothly and fully deploy along a predetermined trajectory during inflation, and reducing the problem of poor deployment caused by space limitations or structural interference, but also allows for direct inspection of whether there are foreign objects blocking the guide groove, damaged parts, or other problems and malfunctions, facilitating the maintenance and inspection of the air curtain guide plate 30. In addition, it can also reduce the manufacturing cost of the vehicle 100 and the weight of the vehicle body 10.

[0071] In some examples of the present invention, an air suction device may be provided on the rear side of the guide groove to facilitate the refolding of the safety curtain 40 after it has been deployed. This not only facilitates the inspection of the safety curtain 40 and avoids the problem of the safety curtain 40 failing to deploy due to long-term disuse, but also facilitates the multiple uses of the safety curtain 40.

[0072] Furthermore, folding buckles can be added to prevent the safety curtain airbags from deploying due to vehicle bumps without affecting their deployment.

[0073] Combination Figure 7 , Figure 9 , Figure 10 and Figure 14 As shown, the air curtain guide plate 30 includes a main plate 307, an upper guide plate 308, a lower guide plate 309, and a rear guide plate 310. The main plate 307 separates the safety air curtain 40 and the air conditioning rear duct 20 in the left-right direction. The upper guide plate 308 is located at the upper end of the main plate 307 and extends away from the air conditioning rear duct 20 in the left-right direction relative to the main plate 307. The lower guide plate 309 is located at the lower end of the main plate 307 and extends away from the air conditioning rear duct 20 in the left-right direction relative to the main plate 307. The rear guide plate 310 is located at the rear end of the main plate 307 and extends away from the air conditioning rear duct 20 in the left-right direction relative to the main plate 307. The main plate 307, the upper guide plate 308, the lower guide plate 309, and the rear guide plate 310 together form a guide groove.

[0074] Specifically, the main body plate 307, upper guide plate 308, lower guide plate 309, and rear guide plate 310 together form a guide groove. All three components—main body plate 307, upper guide plate 308, lower guide plate 309, and rear guide plate 310—can isolate, block, and protect the safety curtain airbag 40. The upper guide plate 308 provides more force to the lower guide plate 309 to prevent the safety curtain airbag 40 from deploying upwards; the lower guide plate 309 extends downwards at the headliner area to prevent scratches from the interior trim, providing safety protection for rear occupants; and the rear guide plate 310 prevents the safety curtain airbag 40 from deploying towards the rear D-pillar inner panel 102, thus avoiding scratches from the D-pillar inner panel 102's sheet metal.

[0075] With this configuration, the guide groove can not only guide the deployment path of the safety curtain 40, allowing it to deploy within a predetermined space to accurately cover the area to be protected, but also provide some support for the safety curtain 40, preventing it from excessively shifting towards the passenger after it droops. This ensures the protective effect of the safety curtain 40 and improves the stability and reliability of the vehicle body 10 structure.

[0076] In some examples of the present invention, the upper guide plate 308, the lower guide plate 309, and the rear guide plate 310 are all at a certain angle to the main body plate 307.

[0077] In some examples of the present invention, the direction of the stamped burrs on the air curtain guide plate 30 is designed to be away from the direction of the safety air curtain 40, thereby preventing the safety air curtain 40 from being scratched when it is deployed.

[0078] Combination Figure 3 , Figure 5 and Figure 8 As shown, the gap between the safety curtain 40 and the curtain guide plate 30 is D1, and D1 satisfies the relationship: 0≤D1≤3mm; and / or the air conditioning rear duct 20 includes the duct body 201 and the buffer 202, the buffer 202 is wrapped around the outside of the duct body 201, the thickness of the buffer 202 is D2, and the gap between the curtain guide plate 30 and the air conditioning rear duct 20 is D3, and D2 and D3 satisfy the relationship: 3mm≤D2≤5mm, D3≥0.

[0079] Specifically, the gap between the safety curtain 40 and the air curtain guide plate 30 is set to be no more than 3mm. The gap setting can not only avoid excessive friction caused by direct contact between the safety curtain 40 and the air curtain guide plate 30, so that the safety curtain 40 can be deployed more smoothly along the air curtain guide plate 30, but also reduce the squeezing effect of the air curtain guide plate 30 on the safety curtain 40 during the deployment process, which can improve the reliability and effectiveness of the safety curtain 40. In addition, the smaller gap setting can save layout space and improve the space utilization rate.

[0080] In some examples of the present invention, when the friction between the structural materials of the safety curtain 40 and the curtain guide plate 30 is small or their structure is elastic, or when other conditions are met, a gap may not be required.

[0081] Furthermore, the rear air duct 20 of the air conditioner may include a duct body 201 and a buffer 202. The buffer 202 is wrapped around the outside of the duct body 201. The thickness of the buffer 202 is required to be between 3mm and 5mm, or it can be 3mm or 5mm. The buffer 202 can be a sponge layer. During the driving of the vehicle 100 or when the vehicle 100 is involved in a collision, the buffer 202 can not only play a buffering role between the rear air duct 20 of the air conditioner and the surrounding parts, avoiding abnormal noise caused by part deformation and shaking, but also play a certain role in heat insulation. It can prevent the cold or hot air in the rear air duct 20 of the air conditioner from being lost during transmission, reduce energy consumption, and avoid unnecessary losses.

[0082] In addition, there may be no gap between the air curtain guide plate 30 and the air conditioning rear duct 20, or a certain gap may be set according to the structural dimensions or requirements.

[0083] In some examples of the present invention, the minimum clearance between the rear air duct 20 and the body-in-white 10 is 5mm, which can avoid interference between the rear air duct 20 and the body-in-white 10, prevent vibration from being directly transmitted from the body-in-white 10 to the rear air duct 20, extend the service life of the rear air duct 20, and improve the stability and reliability of the vehicle 100 structure.

[0084] According to the present invention, the vehicle 100 has a structure with good reliability, which not only provides an installation point for the air curtain guide plate 30, but also enables the safety air curtain 40 to be effectively deployed. When the structure of the vehicle 100 is applied to a vehicle model with rear air conditioning, the rear air conditioning duct 20 can be set between the safety air curtain 40 and the vehicle body 10, and the safety air curtain 40 can be arranged to extend to the rear air conditioning duct 20 and all the way to the rear of the vehicle body 10, thereby improving the safety of the vehicle and effectively protecting the safety of the rear occupants of the vehicle.
