Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention; the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

Example 1

Referring to fig. 1 and 2, a weather strip 1 for a trunk of an automobile includes a weather strip body 101, the surface of the sealing strip body 101 is provided with a groove 109, the groove 109 is internally provided with an adhesive layer 106 for connecting sheet metal parts, a first waterproof lip edge 102 is arranged on one side of the adhesive layer 106, the first waterproof lip edge 102 extends upwards along the upper surface direction of the adhesive layer 106, the height of the first waterproof lip edge 102 is greater than the thickness of the adhesive layer 106, a waterproof groove 104 is arranged between the first waterproof lip edge 102 and the adhesive layer 106, the other side of the sticky layer 106 is provided with a second waterproof lip edge 103, the second waterproof lip edge 103 is tilted outwards, an inclination angle is formed between the second waterproof lip 103 and the sealing strip body 101, the inclination angle is 90-120 degrees, one side of the sealing strip body 101 close to the first waterproof lip 102 is connected with a foaming part 108, and a buffer groove 107 is arranged between the foaming part 108 and the sealing strip body 101.

In the utility model, the adhesive layer 106 is a double-sided pressure-sensitive adhesive, and because the double-sided pressure-sensitive adhesive has the advantages of low curing temperature, good adhesiveness, good temperature resistance and the like, and the adhesive layer 106 is fixed in the groove 109, the double-sided pressure-sensitive adhesive can be easily coated on the sealing strip, and the sealing strip can be more stably fixed with the sheet metal part when the trunk door is closed; the optimal inclination angle between the second lip edge 103 and the sealing strip body 101 is 100 degrees, because if the inclination angle is too low, the second waterproof lip edge 103 causes the problem of difficult installation when the sealing strip is installed, and if the inclination angle is too high, the waterproof performance of the second waterproof lip edge 103 is affected, and rainwater infiltration is caused; first waterproof lip limit 102 can prevent effectively that the rainwater from stretching into in the suitcase, and the capillary groove 104 that sets up simultaneously between first waterproof lip limit 102 and gluing layer 106 can make the rainwater to be saved in capillary groove 104 when stretching into, prevents that the rainwater from further inwards permeating into the suitcase, has improved waterproof performance.

Further, the outer side of the groove 106 is provided with an upwardly projecting waterproof rim 105, the height of the waterproof rim 105 being smaller than the height of the first waterproof lip 102. The waterproof edge 105 is arranged to effectively prevent rainwater permeating into the waterproof groove 104 from further permeating into the sticky layer 106 to affect the viscosity of the sticky layer 106, so that the connection between the sealing strip and the sheet metal part is not firm.

The working principle is as follows: the double-sided pressure-sensitive adhesive is coated in the groove 109 of the sealing strip, and then one side of the double-sided pressure-sensitive adhesive is adhered to the sheet metal part, so that the sealing strip 1 is fixed on the sheet metal part of the trunk, when the trunk door is closed, the trunk door is in contact with the foaming part 108, and the noise caused by the closing of the trunk door can be effectively reduced; simultaneously, the first waterproof lip edge 102 and the second waterproof lip edge 103 which are arranged on two sides of the sealing strip 1 can effectively prevent rainwater from permeating, and the waterproof groove 104 and the waterproof edge 105 prevent the rainwater from further permeating into the adhesive layer, so that the sealing strip 1 is firmly fixed on a sheet metal part.

Example 2

Referring to fig. 3, the difference between the present embodiment and embodiment 1 is: still include guiding gutter 111, guiding gutter 111 sets up on the surface of sealing strip body 101 and is located between sticky layer 106 and the waterproof lip limit 103 of second, and guiding gutter 111's cross-section is the V-arrangement, is equipped with elastic column 110 in buffer slot 107, and elastic column 110's one end is connected with foaming portion 108, and elastic column 110's the other end is connected with sealing strip 1. By arranging the diversion trench 111, when rainwater seeps into the second waterproof lip edge 103, the rainwater flows into the diversion trench 111 and flows out, so that the rainwater is prevented from further seeping inwards; the provision of the resilient posts 110 in the buffer slots 107 further reduces noise caused by the trunk door when closed.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
