Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1, 2 and 3, the sealing strip for the vehicle of the embodiment includes a U-shaped main body 100, the U-shaped main body 100 includes two fixing edges 110 and a tail end 120, one end of each of the two fixing edges 110 is fixedly connected to the tail end 120, and the other end of each of the two fixing edges is close to each other to form a clamping structure, the tail end 120 of the U-shaped main body 100 is fixedly provided with a tongue-shaped buckle 200, the tongue-shaped buckle 200 is fixedly connected to a flange 210, a steel skeleton 130 is arranged in the U-shaped main body 100, the steel skeleton 130 is a U-shaped structure, if the sealing strip with the traditional structure is adopted instead of the sealing strip with the design, because the frame-type vehicle body does not have a door opening seam allowance and an inner protective plate, the sealing property and the aesthetic property of the butt joint between the parts of the traditional sealing strip are not sufficient, the NVH performance is low, the sealing strip with the design is used for sealing, the, the gap and surface difference sealing and absorbing effect is effectively achieved, the outer decoration piece is pressed on the turnover at the joint of the outer decoration piece, and the NVH performance, sealing performance and attractiveness of the whole vehicle are improved.

Two fixed limit 110 of this embodiment include long limit 111 and short side 112, the inboard of short side 112 is equipped with anti-skidding arch 1121, if the inboard of short side 112 is not equipped with anti-skidding arch 1121, because the sealing strip mainly connects structural formula U type, when with part or interior trim backplate joint, there is clearance and gliding defect, cause the not hard up or the problem that the slip drops of sealing strip easily, and the structure of this design has been adopted, the short side 112 inboard is equipped with anti-skidding arch 1121, anti-skidding arch 1121 not only can prevent that the slip of sealing strip on interior trim backplate can also fill the clearance between the part of sealing strip rather than the joint effectively, sealed effect and stability have been improved.

The turn-ups 210 of this embodiment is the cylinder structure, be equipped with a plurality of protruding strips 211 on the lateral wall of turn-ups 210, a plurality of protruding strips 211 are all parallel with the axis of turning over, if turn over and be smooth cylinder structure, turn over and take on the tubular beams when using, because the smoothness is too high, the leakproofness of turning over reduces, smooth turn over simultaneously can not effectual absorption clearance and face difference, it is unobvious to the NVH nature promotion of whole car, and will turn over and be equipped with a plurality of protruding strips 211 on the lateral wall, protruding strip 211 has improved the roughness of turning over, when sealed, mutual extrusion seal between protruding strip 211, the absorption clearance and the face difference that also better when having improved sealing performance, the NVH performance and the leakproofness of whole car have further been improved.

The long side 111 and the short side 112 of the embodiment comprise a movable section 140 and a stable section 150, the steel skeleton 130 is located in the stable section 150 of the long side 111 and the short side 112, due to the existence of the steel skeleton 130, the region supported by the steel skeleton 130 in the whole U-shaped main body 100 is fixed, a connection interior trim panel or a part is more stable in use, if the movable section 140 is not arranged, the U-shaped main body 100 is supported by the steel skeleton 130, when in connection, the sealing strip and the connected piece are purely mechanically clamped, the sealing performance can have a sealing gap due to the error thickness in production of the connected piece, the sealing effect is poor, the movable section 140 is arranged, the steel skeleton 130 is not arranged in the movable section 140, the movable section 140 is attached to the surface of the connected piece under the elastic action of the movable section 140, and the sealing performance is improved.

The tongue-shaped buckle 200 and the U-shaped main body 100 are integrally formed, the tongue-shaped buckle 200 is located on one side of the long edge 111, the outer side face of the tongue-shaped buckle 200 and the outer side face of the long edge 111 are smooth and excessive, when the mechanism designed by the embodiment is used, the contact area between the sealing strip and a connected piece is increased by the integration of the long edge 111 and the tongue-shaped buckle 200, the sealing performance is improved, meanwhile, the whole long edge 111 and the tongue-shaped buckle 200 are located on the outer side, so that the pressed area of the outer side is increased, the pressure is reduced, and the service life of the sealing strip is prolonged.

The turn-ups 210 of this embodiment is located the middle part that the tongue-shaped detained 200, and turn-ups 210 diameter is less than the width of U type main part 100, and the turn-ups is located the tongue-shaped and is detained 200 middle parts throughout, and this design makes the convenience can be when using left the pressurized also right the pressurized, and the practicality improves, and the diameter that turns over simultaneously is less than the width of U nature main part, has guaranteed when sealed, and whole sealed region is throughout in being less than the width of U nature main part, avoids the sealing strip that increases the part clearance and leads to drop.

The above-mentioned embodiments only express a certain implementation manner of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention; therefore, the protection scope of the present invention should be subject to the appended claims.
