[0001] The utility model relates to the technical field of vehicle parts, and more specifically to a sealing structure and a vehicle with the sealing structure. Background Art

[0002] At present, a cavity structure is usually formed in the pillar of the car, which will affect the NVH performance of the car. Therefore, the existing technology is to set a sealing part in the cavity for sealing. However, the sealing parts in the existing technology have defects such as unreasonable arrangement or unreasonable structure of the parts themselves, which affect the electrophoretic performance of the cavity or fail to completely and effectively seal the cavity, and the limited pressure resistance leads to the risk of the vehicle being unable to withstand the large water pressure and being broken when the wading depth is large, which leads to the easy rust of the car cavity or the entry of noise and water outside the car into the passenger compartment, reducing the service life of the car, riding comfort and shortening the floating time of the vehicle.

[0003] Therefore, it is necessary to provide a sealing structure and a vehicle to at least partially solve the above problems. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the utility model proposes a sealing structure to effectively improve the sealing performance of the cavity of the vehicle pillar, and avoid problems such as water corrosion caused by the vehicle cavity structure and noise caused by airflow entering the cavity.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A sealing structure, comprising a frame and a filling member: wherein the frame comprises a main body and a convex portion with at least one end being an acute angle, and within the plane where the first side surface of the main body is located, the first convex portion is suitable for forming an angle with two side edges connected to two side walls of a vehicle cavity, and the angle is an acute angle, that is, at least one end of the convex portion is an acute angle. The filling member may be a foam material and is connected to the frame. The structure can block the cavity in which it is located, making the cavity a sealed space, and can block the flow of gas and liquid in the cavity.

[0008] In some embodiments, the sealing structure can be installed in the A-pillar or B-pillar of the vehicle and connected to the inner panel of the A-pillar or B-pillar of the vehicle. The sealing of the vehicle cavity structure is achieved by expanding and foaming the foaming material on the sealing structure, thereby blocking the airflow and water outside the vehicle from entering the passenger compartment through the cavity, thereby reducing the noise outside the vehicle, improving the NVH performance of the vehicle, improving ride comfort, and increasing the wading depth of the vehicle and extending the floating time of the vehicle.

[0009] A sealing structure has at least one first protrusion with an acute angle at one end. Since the edges of the inner panel cross section of the vehicle's B-pillar or A-pillar have sharp-angled gap areas at both ends, the shape of the first protrusion is designed to fit the sharp-angled areas of the B-pillar or A-pillar, which can effectively block the cavity structure and form a closed space, which is beneficial to improving the NVH performance of the vehicle.

[0010] In some embodiments, the sealing structure is connected to the inner panel of the B-pillar of the vehicle, and the first protrusion is placed in the sharp angle area of ​​the cross-section of the inner panel of the B-pillar. The shapes of the first protrusion and the sharp angle area basically match, which can effectively block the cavity structure and form an enclosed space, which is beneficial to improving the NVH performance of the vehicle.

[0011] A sealing structure, the frame also includes a fixing piece, the fixing piece is suitable for connecting with a filling piece and fixing it on the frame, which can ensure that the filling piece is more firmly combined with the frame and prevent the filling piece from falling off the frame during expansion and foaming, resulting in poor sealing effect.

[0012] In some embodiments, there is a fixing piece on the frame, the filling piece is injection molded on the frame by an injection molding process, and the foaming material wraps the fixing piece, and a fixing hole is formed on the filling piece. Therefore, the filling piece is more firmly combined with the frame, so that the foaming material can be firmly and stably fixed on the frame when expanding and foaming, and will not fall off, thereby improving the sealing effect of the sealing structure.

[0013] A sealing structure includes a fixing member, which is divided into a first fixing part and a second fixing part.

The first fixing portions can fix the foaming material at the edge of the frame to the frame, which can effectively prevent the foaming material at this location from falling off and causing poor sealing effect.

[0015] A sealing structure has a main body provided with at least one through hole, so that gas or liquid can flow through the through hole to pass through the sealing structure.

[0016] In some embodiments, the through hole can be an electrophoresis hole.

[0020] In some embodiments, two sink structures may be provided on the frame, and each sink structure is provided with a foaming material. When the foaming material is baked and expands and foams, due to the obstruction of the sink structure, the foaming material will rapidly foam in the direction close to the electrophoresis hole until the electrophoresis hole is completely blocked. Therefore, it can be avoided that the foaming material foams around, and the electrophoresis hole is not completely blocked, resulting in a poor sealing effect.

[0021] A sealing structure, the main body also includes at least one rib, both ends of the rib are connected to the hole wall of the through hole, this arrangement can improve the bearing strength of the through hole position, which is conducive to the realization of the sealing effect.

[0057] In some embodiments, at least one through hole is provided.

[0058] Specifically, a through hole 1131 is provided on the main body 111 of the skeleton 11. The through hole 1131 is an electrophoresis hole for circulating the electrophoresis liquid in the cavity to avoid the risk of rust due to poor electrophoresis on the inner surface of the cavity; and a sinking platform structure 113 is also provided on the skeleton 11, which plays a role in guiding the foaming direction of the filler 12 at the electrophoresis hole position. The electrophoresis hole is arranged on the sinking platform structure 113, and a rib 1132 is provided on the hole wall of the electrophoresis hole. The rib 1132 is intended to improve the pressure bearing capacity of the electrophoresis hole position to prevent the water pressure from being too high when the vehicle is wading and destroying the blocking effect at the electrophoresis hole; the sealing structure 1 is also provided with a first guide part 115, a second guide part 114 and a third guide part. The first guide part 115 includes a first fixing plate 1151 arranged on the side wall of the skeleton 11 and a plurality of second fixing plates 1151 arranged at intervals along the second direction. A fixing plate 1152, wherein a first fixing plate 1151 and a plurality of second fixing plates 1152 are spaced apart in the first direction to form a U-shaped accommodating cavity, the accommodating cavity is used to accommodate the filling piece 12, and plays a role in guiding the foaming direction of the filling piece 12 here; in addition, the sealing structure 1 also includes a second guide portion 114, the second guide portion 114 is a plurality of plates extending along the first direction, and the second guide portion 114 and the second fixing portion 1133 are both on the same side of the skeleton 11, and the second guide portion 114 plays a role in guiding the foaming direction of the filling piece 12 here; and the sealing structure 1 also includes a fixing member, that is, a raised cylindrical reinforcement shaft, the fixing member includes a plurality of first fixing portions 116 raised along the first direction, and two adjacent first fixing portions 116 are arranged at intervals and are arranged around the edge of the skeleton 11.

In addition, the frame 11 may also be provided with reinforcing ribs 118, which are arranged at least between the two sink structures 113 and extend to both ends of the frame 11 in the second direction. The reinforcing ribs 118 can improve the pressure bearing capacity of the sealing structure.

[0059] In the sealing structure 1 of this embodiment, the filler 12 is a foaming material, and baking can make the filler 12 expand and foam, playing the role of closing the cavity structure; and the connection between the first protrusion 112 and the inner plate of the vehicle A-pillar or the first protrusion 112 and the inner plate 21 of the vehicle B-pillar is coated with an adhesive 4, that is, a structural adhesive, to seal the connection between the first protrusion 112 and the inner plate of the A-pillar or the first protrusion 112 and the inner plate 21 of the vehicle B-pillar. When the vehicle is wading, the filling member 12 is expanded and foamed by baking, so that the foamed filling member 12 can block the vehicle cavity, forming a well-sealed closed space, avoiding the defects of easy rust in the car cavity or external noise and water entering the passenger compartment, reducing the service life of the car, riding comfort and shortening the floating time of the vehicle.

[0060] Based on the above overall introduction, the sealing structure 1 of this embodiment and an exemplary structure of a vehicle are shown in the figure, and this embodiment is described by taking the cavity structure in the B-pillar of the vehicle as an example. Of course, in addition to being arranged on the B-pillar of the vehicle, the sealing structure 1 of this embodiment can also be arranged on the A-pillar of the vehicle.

[0061] In this embodiment, the sealing structure 1 , the vehicle B-pillar and the door sill 3 , the vehicle B-pillar inner plate 21 and the vehicle B-pillar reinforcement plate 22 form a cavity structure, and the sealing structure 1 can be arranged in the cavity structure.

[0062] Specifically, a side wall of the sealing structure 1 is connected to the weld between the inner plate 21 of the vehicle B-pillar and the reinforcing plate 3 of the door sill, wherein the third fixing portion 117 of the sealing structure 1 is connected to the inner plate 21 of the vehicle B-pillar, and the connection method can be a screw, or a buckle or a latch. The acute angle end of the first protrusion 112 of the skeleton 11 and the main body 111 are connected to the side wall of the inner plate 21 of the vehicle B-pillar and basically fit, and the first guide portion 115 of the skeleton 11 is connected to the side wall of the reinforcing plate 22 of the vehicle B-pillar and basically fits. In addition, in order to ensure the sealing of the cavity in the B-pillar, in this embodiment, the adhesive 4 is arranged at the connection between the first protrusion 112 and the inner plate 21 of the vehicle B-pillar, and at the connection between the inner plate 21 of the vehicle B-pillar and the reinforcing plate 22 of the vehicle B-pillar, so that there is no connection gap in the top view cross section of the cavity structure, and the sealing of the blocked part is better.

[0063] In this embodiment, the sealing structure 1 further includes a filling member 12. The filling member 12 is a foaming material and is injection-molded on the frame 11 to play the role of closing the cavity structure.

[0064] In addition, the sealing structure 1 of the present embodiment also includes two sinker structures 113, each sinker structure 113 is provided with an electrophoretic hole, three ribs 118 and a second fixing portion 1133, wherein the filling piece 12 is connected to the sinker structure 113 through a fixing piece; the electrophoretic hole can be an oblong hole with a size of about 8×58 mm, so that the electrophoretic liquid in the vehicle body cavity can flow smoothly, ensuring that the thickness of the sheet metal electrophoretic film in the cavity meets the requirements and avoiding premature rusting of parts; in addition, the second fixing portion 1133 is wrapped in the filling piece 12, which can effectively fix the filling piece 12, and avoid the filling piece 12 becoming soft and falling off due to the foaming temperature not being reached during baking, thereby causing the cavity to be unable to be isolated.

[0065] Specifically, when the vehicle is running or stopped normally, the filler 12 does not need to expand and foam, the electrophoresis hole is in an open state, and the electrophoresis liquid can flow in the electrophoresis hole, which can effectively prevent the inner surface of the cavity structure from rusting due to poor electrophoresis. When the vehicle needs to close the cavity structure in the B-pillar, the driver can turn on the switch to bake the filler 12. At this time, the filler 12 at the sink structure 113 is baked and expanded and foamed, and the side wall of the sink structure 113 guides the filler 12 to expand and foam in the direction of the electrophoresis hole. The filler 12 foams and completely blocks the electrophoresis hole and wraps the rib 1132 under the guidance of the side wall of the sink structure 113. The rib 1132 provides support for the foam glue, which improves the pressure-bearing capacity of the deep wading cavity blocking of the vehicle. At this time, the electrophoresis hole is in a completely closed state.

[0066] The sealing structure 1 of this embodiment further includes a first guide portion 115, wherein a accommodating cavity formed by a first fixing plate 1151 and a plurality of second fixing plates 1152 is provided with a filler 12, wherein the ratio of the second fixing plate 1152 to the filler 12 can be 1:1 to 1:1.3. Moreover, in the third direction, the second fixing plate 1152 and the second guide portion 114 are provided on both sides of the sink structure 113.

[0067] Specifically, when the vehicle needs to seal the cavity structure in the B-pillar, the driver can turn on the switch to bake the filling piece 12. At this time, the filling piece 12 of the first guide part 115 is baked and expanded and foamed. The first fixed plate 1151 and the second fixed plate 1152 guide the filling piece 12 to expand and foam in the direction away from the sink structure 113. The multiple second fixed plates 1152 guide the filling piece 12 to expand and foam in the first direction, so that the filling piece 12 wraps the second fixed plate 1152, thereby increasing the adhesion between the filling piece 12 and the skeleton 11, and improving the pressure-bearing capacity of the sealing structure 1. The filling piece 12 foams under the guidance of the first guide part 115 and completely blocks the connection between the sealing structure 1 and the vehicle B-pillar reinforcement plate 22.

[0068] The sealing structure 1 of this embodiment further includes a plurality of second guide portions 114 arranged at intervals, wherein the filling member 12 is arranged on a side of the second guide portion 114 away from the sink structure 113 .

[0069] Specifically, when the vehicle needs to seal the cavity structure inside the B-pillar, the driver can turn on the switch to bake the filling piece 12. At this time, the filling piece 12 of the second guide part 114 expands and foams due to baking. Multiple second guide parts 114 guide the filling piece 12 to expand and foam in the direction away from the sink structure 113 and in the first direction at the same time. The filling piece 12 foams under the guidance of the second guide part 114 and completely blocks the connection between the sealing structure 1 and the inner panel 21 of the vehicle's B-pillar, and also completely blocks the connection between the inner panel 21 of the vehicle's B-pillar and the reinforcement plate of the door sill 3.

[0070] The sealing structure 1 of the present embodiment also includes an adhesive member 4, which can be a structural adhesive. Four lines of structural adhesive are connected to the acute-angled end of the first protrusion 112; the direction of one line of structural adhesive is parallel to the thickness direction of the first protrusion 112, and the line of adhesive is connected to the acute-angled end of the first protrusion 112 and the vehicle B-pillar reinforcement plate 22, and the other three lines of structural adhesive are applied along the extension direction of the first protrusion 112, and the structural adhesive covers the acute-angled end of the first protrusion 112 and extends to the welding surface of the vehicle B-pillar reinforcement plate 22. At the same time, these three lines of structural adhesive are also connected to the structural adhesive between the vehicle B-pillar reinforcement plate 22 and the vehicle B-pillar inner plate 21, so that there is no connection gap in the cavity structure, and the sealing of the blocking point is better.

[0071] Specifically, when the driver turns on the switch to bake the filling member 12, according to the description of the above embodiment, the filling member 12 is fully expanded and foamed, and the connection between the sealing structure 1 and the B-pillar and the electrophoretic hole itself are in a closed state, which can block the vehicle cavity, form a well-sealed enclosed space, and prevent the airflow and water outside the vehicle from entering the passenger compartment through the cavity, thereby reducing the external noise, improving the NVH performance of the vehicle, improving ride comfort, and increasing the wading depth of the vehicle and extending the floating time of the vehicle.
