A sealing structure 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 6.
As shown in fig. 1 and 2, a sealing structure 100 according to an embodiment of the present invention includes: the carrier 30 and the sealing tape 10 are mounted. Wherein, the mounting carrier 30 is provided with a positioning hole 31, the sealing strip 10 is provided with a positioning protrusion 20 integrally formed therewith, and the positioning protrusion 20 is fitted to the positioning hole 31 to mount the sealing strip 10 on the mounting carrier 30.
Specifically, the sealing structure 100 is used for sealing a gap between two adjacent target members, wherein the mount carrier 30 is constructed of one of the two target members, and the other of the two target members functions to seal the gap between the two target members by pressing the weather strip 10 to closely adhere the weather strip 10 to the mount carrier 30. The positioning projection 20 is formed integrally with the weather strip 10, that is, the positioning projection 20 is formed integrally with the weather strip 10, and the positioning projection 20 is adapted to be fitted into the positioning hole 31 of the mounting carrier 30 to fix the weather strip 10 to the mounting carrier 30.
According to the sealing structure 100 of the embodiment of the invention, the sealing strip 10 and the positioning protrusion 20 are integrally formed, and compared with the prior art that the sealing strip is provided with the metal insert to be matched with the mounting carrier in a positioning manner, the positioning protrusion 20 and the sealing strip 10 of the embodiment of the invention are integrally formed, the structure is simple, the processing is convenient, the consistency of the whole structure is better, and the sealing structure is not easy to damage. Furthermore, the sealing strip 10 can be installed on the installation carrier by matching the positioning protrusion 20 with the positioning hole 31, and the assembly is more convenient compared with the prior art in which the metal inlaid hook on the sealing strip 10 needs to be matched with the installation carrier 30.
Therefore, the sealing structure 100 according to the embodiment of the present invention has the advantages of good structural strength, less damage and convenient assembly.
In some embodiments of the present invention, the positioning protrusion 20 and the sealing tape 10 are an integral elastic member. Specifically, the positioning protrusion 20 and the sealing strip 10 are manufactured through an integrated processing and forming process, the consistency of the whole structure is good, the positioning protrusion 20 and the sealing strip 10 are made of elastic materials, when the sealing strip is assembled, the positioning protrusion 20 is elastically deformed and inserted into the positioning hole 31 under the action of external force, and the positioning protrusion 20 is tightly matched with the positioning hole 31 under the action of the elasticity of the positioning protrusion 20, so that the matching effect of the positioning protrusion 20 and the positioning hole 31 is further improved, and the sealing strip is more convenient to install; moreover, the sealing strip 10 is deformed by the extrusion of the two target components, and the sealing strip 10 can better fill the gap between the two target components due to the self elastic action, so that sundries such as water and the like are prevented from entering the gap between the two target components, and the waterproof and dustproof effects are improved.
In some alternative examples of the present invention, as shown in fig. 3 and 4, the positioning protrusion 20 is provided with a catching groove 201 extending along a circumferential direction thereof, and an edge of the positioning hole 31 is caught in the catching groove 201 by elastic deformation of the positioning protrusion 20.
Specifically, the side surface of the positioning protrusion 20 is provided with an inward recessed locking groove 201, the locking groove 201 extends along the circumferential direction of the positioning protrusion 20, and the positioning protrusion 20 enters the positioning hole 31 through elastic deformation until the edge of the positioning hole 31 is locked in the locking groove 201. Preferably, the diameter of the positioning protrusion 20 is not smaller than the diameter of the positioning hole 31, so that after the edge of the positioning hole 31 is clamped in the clamping groove 201, the positioning hole 31 is not easily separated from the positioning protrusion 20, thereby improving the fixing effect of the sealing strip 10 and the mounting carrier 30.
In some specific examples of the present invention, as shown in fig. 4, the positioning boss 20 includes: a connecting portion 21 and a tapered portion 22.
Wherein, the connecting portion 21 is connected to the sealing strip 10, the tapered portion 22 is connected to the connecting portion 21 and the cross-sectional area of the tapered portion 22 gradually decreases towards the direction away from the connecting portion 21, the maximum cross-sectional area of the tapered portion 22 is larger than the cross-sectional area of the connecting portion 21, and the clamping groove 201 is defined by the tapered portion 22, the connecting portion 21 and the sealing strip 10 together.
Specifically, the tapered portion 22 is generally in the shape of a circular truncated cone, the cross section of the tapered portion 22 passing through the central axis thereof is generally in the shape of an isosceles trapezoid, during the assembling process, as shown in fig. 2, the end with the smaller cross section of the tapered portion 22 first enters the positioning hole 31, and then the tapered portion 22 continues to enter the positioning hole 31 through elastic deformation until the end with the larger cross section of the tapered portion 22 passes through the positioning hole 31, as shown in fig. 5 and 6, the edge of the positioning hole 31 is clamped in the clamping groove 201, and the assembling of the sealing strip 10 and the mounting carrier 30 is completed. Therefore, the sealing strip 10 is convenient and labor-saving to mount, the matching effect between the positioning protrusion 20 and the positioning hole 31 is better, and the connecting effect between the sealing strip 10 and the mounting carrier 30 is further improved.
Further, the maximum cross-sectional area of the tapered portion 22 is greater than the inner diameter of the positioning hole 31, and the minimum cross-sectional area of the tapered portion 22 is smaller than the inner diameter of the positioning hole 31, so that the tapered portion 22 can be ensured to clamp the edge of the positioning hole 31 in the clamping groove 201 through elastic deformation, and the positioning protrusion 20 cannot be separated from the positioning hole 31, thereby further improving the fixing effect of the sealing strip 10 and the installation carrier 30.

Further, the width of the slot 201 is less than or equal to the thickness of the flange 32. The width of draw-in groove 201 is the distance between the great terminal surface of conical section 22 cross-sectional area and the sealing strip 10 for promptly, like this, turn-ups 32 card is established behind draw-in groove 201, because the width of the thickness more than or equal to draw-in groove 201 of turn-ups 32, draw-in groove 201 takes place elastic deformation so that the part chucking at turn-ups 32's locating hole 31 border is in draw-in groove 201, the terminal surface of conical section 22 hugs closely respectively in two sides of turn-ups 32 with the side of sealing strip 10 promptly, draw-in groove 201 is better to the spacing effect of turn-ups 32 in the axial of connecting portion 21, thereby further promote the fixed effect.
