It is noted that the drawings are not only for explanation and illustration of the present invention, but also for contributing to the definition of the present invention when necessary.
The utility model discloses in fact be the improvement of making on the basis that does not change the basic structure and the performance of current door frame sealing strip. The door frame sealing strip generally includes a fixing portion configured to fix the door frame sealing strip on a door frame sheet metal, and a sealing portion including a contact surface for contacting a vehicle body sheet metal to be in close contact with the vehicle body sheet metal when the door is closed, thereby achieving sealing between the door and the vehicle body.
Fig. 2 is a partial perspective view of a door frame sealing strip 1 according to the present invention; fig. 3 is a partial perspective view of a door assembly including the door frame seal 1 of fig. 2; fig. 4 is a schematic cross-sectional view of the vehicle door assembly of fig. 3. In the illustrated embodiment, the door assembly includes a door frame metal plate 3, and a door frame decoration 2 and a door frame sealing strip 1 which are disposed on the door frame metal plate 3, the door frame decoration 2 is fixed on the edge of the door frame metal plate 3 by means of, for example, screw connection, adhesion, clamping, and the like, and the door frame sealing strip 1 is clamped on the door frame metal plate 3 by means of the door frame decoration 2.
More specifically, as shown in fig. 4 in particular, a first clamping portion 21 is formed on the door frame trim strip 2, a second clamping portion 22 is formed by the door frame trim strip 2 and the door frame metal plate 3 together, and the fixing portion of the door frame sealing strip 1 includes a first buckle 11 and a second buckle 12 to be respectively clamped and matched with the first clamping portion 21 and the second clamping portion 22, so that the door frame sealing strip 1 is fixed on the edge of the door frame metal plate 3.
According to the utility model discloses, door frame sealing strip 1 made by rubber is still including arranging the flocking layer on the contact surface 14 that is used for contacting the automobile body panel beating of its sealing part 13. The contact surface 14, which is the flocked surface, is substantially planar, so the electrostatic flocking process employed is simple to operate, has a uniform distribution of the flock, and has good stability of the production process and good appearance quality. Preferably, the thickness of the flocking layer is 1-2mm, the flocking fluff can adopt polyurethane fiber fluff, the length of the fluff is 0.5-1mm, the fiber linear density is 1-2dtex, and the color is black. Through the verification of the endurance test, the flocking sealing strip with better fluff retention can effectively solve the problems of knocking and friction abnormal sound of the vehicle door and the vehicle body.
The production process of the sealing strip 1 for the door frame of the vehicle door comprises two processes of extrusion vulcanization and gluing flocking, wherein the extrusion vulcanization process is the same as that of a common rubber sealing strip, and the gluing flocking process comprises pretreatment, gluing, electrostatic flocking and curing. The pre-treatment is to polish the contact surface 14 with a metal brush to roughen the flocked surface to facilitate subsequent application of adhesive and flocking. The adhesive is evenly sprayed on the flocked surface of the rubber sealing strip. Electrostatic flocking is to make the rubber sealing strip coated with adhesive pass through the electrostatic flocking box, and the charged fluff moves into the precoated adhesive layer under the action of electrostatic field. The curing is carried out by passing the electrostatically flocked sealing strip through a heated channel and curing the adhesive to retain the flock on the rubber flocked surface.
