Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a side air curtain guide plate, a side air curtain assembly and a vehicle. Background Art

[0002] The strength and rigidity of the structural parts on the side of the vehicle body are far inferior to those of the longitudinal structural parts. There is not enough space on both sides of the door to arrange buffer structures to deform and absorb the energy during collision, and the seat belts' protection against side collisions is also much lower. The main areas of injury to the occupants in side collisions are concentrated in the head, neck, chest, abdomen, etc. The function of the side airbags is to inflate and expand in a very short time at the moment of a side collision accident, forming curtain-like airbags that cover the side windows of the front and rear rows, preventing the occupants' heads from directly colliding with the window frames or external objects. In order to better protect the occupants, side airbags have now become standard equipment in most passenger cars.

[0003] In the event of a collision, the side curtain airbag's direction of deployment is uncertain, so a guide assembly is required underneath the side curtain airbag to ensure that the deployed side curtain airbag reaches the vehicle's occupants precisely and protects them. Furthermore, when driving on uneven roads, the side curtain airbag's connection to the vehicle body is not completely locked, causing it to swing significantly up and down relative to the vehicle body. If an unexpected situation causes the side curtain airbag to deploy, this can easily interfere with its direction and reduce its protective effectiveness. Therefore, an auxiliary positioning mechanism is also required. However, the numerous structures near the side curtain airbag make it easy for fragments to injure vehicle occupants when it deploys. Therefore, it is necessary to propose a simple side curtain airbag guide plate that simultaneously guides and positions the vehicle. Utility Model Content

[0004] The purpose of the utility model is to provide a side air curtain guide plate, a side air curtain assembly and a vehicle, which solves the problem that the side air curtain cannot accurately reach the position of the occupants in the vehicle when it explodes, and provides good guiding and positioning effects for the side air curtain.

[0034] Embodiment 1

[0035] See Figures 1-3 As shown, a side air curtain guide plate 10 provided by the embodiments of the present application includes:

[0036] A connecting plate 1, the upper end of the connecting plate 1 is fixed on the upper inner plate 4 of the B-pillar;

[0037] An assembly plate 2, the assembly plate 2 is fixedly connected to the lower end of the connecting plate 1, and the assembly plate 2 forms an angle adapted to the blasting trajectory of the side air curtain 3 with the plane where the door is located;

[0038] An accommodation space for accommodating the side air curtain 3 is formed among the assembly plate 2, the connecting plate 1 and the upper inner plate 4 of the B-pillar.

[0039] The guide plate 10 is fixed to the upper inner panel 4 of the B-pillar through the connecting plate 1. The assembly plate 2 is used to guide the side airbag 3 located above the assembly plate 2. The side airbag 3 is detonated along the upper surface of the assembly plate 2 through the side airbag guide plate 10, ensuring that the side airbag 3 falls to an accurate position and plays a good protective role for the vehicle occupants. At the same time, when the vehicle is driving on an uneven road section, the side airbag may swing up and down significantly following the vehicle. By installing the side airbag 3 in the accommodation space formed between the assembly plate 2, the connecting plate 1 and the upper inner panel 4 of the B-pillar, since the lower end of the side airbag 3 is supported by the assembly plate 2, it can avoid the side airbag 3 from swinging too much, affecting the deployment direction during detonation, increasing the stability of the side airbag 3 and ensuring a good protective effect.

[0040] See Figures 1-3 As shown, the angle formed by the assembly plate 2 and the plane where the door is located is 115 - 135°.

[0041] When the angle formed by the assembly plate 2 and the plane where the door is located is 115 - 135°, it has a good protective effect. Since the guide plate 10 is integrally installed at the upper inner panel 4 of the B-pillar, that is, the top of the door, the angle between the assembly plate 2 and the plane where the door is located during the vehicle driving process, that is, the XZ plane of the vehicle coordinate system (measurement method of the vehicle coordinate system: the origin of the vehicle coordinate system coincides with the centroid. When the vehicle is in a stationary state on a horizontal road surface, the X-axis is parallel to the ground and points to the front of the vehicle, the Z-axis passes through the vehicle centroid and points upward, and the Y-axis points to the left of the driver) is 115 - 135°, the deployed side airbag 3 inclines downward and exactly aims at the vehicle occupants.

[0042] See Figures 1-3 As shown, an arc transition surface is provided at the connection between the lower ends of the assembly plate 2 and the connecting plate 1, and a strengthening structure 22 is provided on the transition surface.

[0043] The strengthening structure 22 is a strengthening boss and / or a strengthening rib, which can strengthen the overall sheet metal strength and avoid deformation of the guide plate 10 during detonation, affecting the guiding effect on the side airbag 3. The strengthening structure can have various forms and can be selected according to the strength requirements and actual situation.

[0044] See Figures 1-3 As shown, the edges of the connecting plate 1 and the assembly plate 2 are chamfered by 5, and the lower end of the assembly plate 2 is a flanging structure 23.

[0045] The design of the chamfer 5 and the flanging structure 23 is to make the overall edge of the guide plate 10 a smooth structure, thereby avoiding damage to the side airbag 3 caused by the straight edge and burrs of the guide plate 10, ensuring the integrity of the side airbag 3, and thus protecting the vehicle occupants. The guide plate 10 is a sheet metal part, the material thickness is 1.5 - 2.0 mm, and the size range of the chamfer is between R0.5 - 0.7 mm. The specific material thickness selection and chamfer size can be selected according to the actual situation.

[0046] See Figures 1-3 As shown, the top of the connecting plate 1 is connected to the upper inner plate 4 of the B-pillar by welding.

[0047] Connected to the upper inner plate 4 of the B-pillar by welding, the connection is tighter and the overall structural strength is higher.

[0048] See Figures 1-3 As shown, the assembly plate 2 is provided with positioning holes 21, and the connecting plate 1 is welded and positioned through the positioning holes 21. There can be two positioning holes, the main positioning hole auxiliary positioning hole

[0049] The positioning holes 21 can be used in cooperation with positioning pins, which is convenient for positioning the guide plate 10 during the production process and the welding process.

[0050] See Figures 1-3 As shown, the assembly plate 2 is provided with weight-reducing holes.

[0051] Weight-reducing holes can be opened on the assembly plate 2 according to the vehicle model requirements, so as to reduce the weight of the overall sheet metal structure and achieve the lightweight goal.

[0052] Furthermore, the left and right structures of the guide plate 10 in the present utility model are the same in the whole vehicle. Any one of the guide plates 10 can be selected to open process anti-misalignment holes on the assembly plate 2 to help distinguish left and right during the production process and the welding process, thereby improving efficiency.

[0053] Embodiment 2

[0054] See Figures 1-4 As shown, an embodiment of the present application provides a side air curtain assembly, including:

[0055] The above-mentioned side air curtain guide plate 10 and side air curtain 3, the side air curtain 3 is arranged in the accommodation space, and the side air curtain 3 is screwed to the upper inner plate 4 of the B-pillar.

[0056] The side air curtain 3 is located in the accommodation space, so as to prevent the side air curtain 3 from shaking greatly when the vehicle is driving on an uneven road section, affecting the unfolding effect of the side air curtain 3. The side air curtain 3 is relatively long, spanning the upper inner plate of the B-pillar and the upper inner plate of the C-pillar, and is provided with a plurality of screw joints at the upper end, so as to be screwed to the upper inner plate of the B-pillar or the upper inner plate of the C-pillar, so as to protect the vehicle occupants when the side air curtain 3 explodes and unfolds.

[0057] The upper inner panel of the B-pillar has a bent portion. On both sides of the bent portion are the first inner panel and the second inner panel respectively. The first inner panel is located inside the door. Inside the upper part of the first inner panel, a side airbag 3 is fixedly connected. Inside the lower part of the first inner panel, a connecting plate 1 is fixedly connected. The second inner panel is located at the top of the vehicle body. The second inner panel, the upper part of the first inner panel, the connecting plate 1, and the assembly plate 2 form a receiving space for the side airbag 3.

[0058] The side airbag 3 includes an airbag assembly 32, a gas generator 31, a tie strap 33, and a pull strap 34. The outer shell of the airbag assembly 32 and the gas generator 31 located above the airbag assembly 32 are fixedly connected. The gas generator 31 is screwed to the first inner panel of the upper part of the B-pillar 4. Under normal conditions, the tie strap 33 is tied to the gas generator 31 and the outer shell of the airbag assembly 32. During blasting, due to the inflation of the airbag inside the airbag assembly 32, the tie strap 33 breaks. After that, the airbag continues to be inflated by the gas generator 31 and quickly unfolds along the upper surface of the assembly plate 2, thus realizing the protection of the heads of the vehicle occupants. The pull strap 34 is designed because during the unfolding process, the airbag shakes violently. A pull strap 34 is designed at the front part of the airbag assembly 32. One end of the pull strap 34 extending out of the airbag assembly 32 is hung on a hook provided on the vehicle body.

[0059] Furthermore, since the side airbag 3 is relatively long, if only the middle part is located inside the receiving space and supported by the assembly plate 2, it is still easy for the two ends of the side airbag 3 to swing up and down too much when the vehicle is running. Therefore, one or more support plates 6 are installed below the two ends of the side airbag 3 extending beyond the guide plate 10. The support plates 6 are fixed to the vehicle body by means of clamping, etc. The side airbag 3 is fixed above the support plates 6 by a binding strap. During blasting, the binding strap breaks, and the airbag inside the airbag assembly 32 unfolds downward along the upper surface of the assembly plate 2 of the guide plate 10. In addition, fixing plates 7 can also be provided above the two ends of the side airbag 3 extending beyond the guide plate 10. The upper end of the outer shell of the airbag assembly 32 of the side airbag is clamped to the fixing plate 7.

[0060] Furthermore, a side airbag guide plate 10 can also be installed on the upper inner panel of the C-pillar, so as to cancel the support plate 6 and use two side airbag guide plates 10 at the same time, which has a better guiding effect on the side airbag 3.

[0061] Furthermore, a clamp is welded on the gas generator 31.

[0062] Embodiment 3

[0063] The embodiment of the present application provides a vehicle, including the above-mentioned side airbag assembly.

[0064] The working principle of the present utility model is:

[0065] When the vehicle travels on an uneven road section, since the side air curtain 3 is arranged in the accommodation space and the lower end of the side air curtain 3 is supported by the guide plate 2, the shaking amplitude is small. When blasting, the side air curtain 3 unfolds downward along the upper surface of the assembly plate 2. Since the angle between the assembly plate 2 and the surface where the car door is located is 115-135°, the side air curtain 3 can accurately align with the side of the head of the vehicle occupants, realizing the protection of the vehicle occupants.

[0066] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
