DETAILED DESCRIPTION

[0036] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0037] This utility model provides, for example Figures 1-6 The high-sealing single-seal strip for a side window glass, as shown, includes: a mounting component 1 and a side window glass 3, which are mounted on the vehicle body; a sealing mechanism 2, which is mounted on the mounting component 1 and includes: a guide rail frame structure 21, which is mounted on the bottom of the mounting component 1; and a sealing structure 22, which is mounted on the guide rail frame structure 21. The guide rail frame structure 21 is arranged along the length of the sealing structure 22, enhancing the overall strength and stability of the sealing structure 22, preventing deformation or twisting during installation and use, and ensuring sealing performance. The sealing structure 22 is reliable and is used for contact sealing of the side window glass 3. Compared with traditional multi-seal strips, the sealing structure 22 reduces the number of parts, reduces manufacturing costs and installation difficulty, and effectively blocks the entry of external noise, dust, rain and hot and cold air, greatly improving the sealing and comfort of the vehicle interior. The mounting bracket 23 is respectively snapped onto both ends of the guide rail frame structure 21. The mounting bracket 23 is assembled into the interior of the vehicle body. The cooperation between the mounting bracket 23 and the vehicle body facilitates the installation of the guide rail frame structure 21, which in turn facilitates the installation of the sealing structure 22.

[0038] The sealing structure 22 comprises: a mounting base 221 mounted on the guide skeleton structure 21 and extending along the bending direction of the guide skeleton structure 21, the material of the mounting base 221 being EPDM dense rubber; a lip frame 222 mounted on the mounting base 221; and a lip edge 223 mounted on the end of the mounting base 221, the materials of the lip frame 222 and the lip edge 223 being EPDM sponge rubber. The main material of the sealing structure 22 is EPDM, and carbon black and plasticizer are added. The EPDM accounts for 70%-85% of the total material mass, the carbon black accounts for 5%-15%, and the plasticizer accounts for 5%-10%. The addition of carbon black enhances the wear resistance and anti-aging performance of the material, and the plasticizer improves the processing performance and flexibility of the rubber, so that the sealing structure 22 can maintain good performance in different environments. The manufacturing process of the sealing structure 22 includes: 1. Extrusion molding: the mixed rubber material is extruded by a screw extruder, the extrusion temperature is controlled at 120-150°C, the screw rotation speed is 30-50 r / min, and the basic shape of the sealing strip is formed by a special mold. 2. Secondary vulcanization: the sealing strip after extrusion molding is subjected to secondary vulcanization treatment, the vulcanization temperature is 160-180°C, and the vulcanization time is 10-20 minutes, so as to further improve the cross-linking degree of the rubber material and enhance its physical properties and chemical stability. 3. Surface treatment: the surface of the sealing strip is treated by plasma treatment technology, the treatment power is 100-300W, and the treatment time is 3-5 minutes, so as to improve the wear resistance and self-lubricity of the surface of the sealing structure 22, reduce the friction resistance between the glass and the sealing strip, and make the glass lifting more smoothly. Through the combination of the main material of EPDM, carbon black and plasticizer, and the secondary vulcanization and surface treatment processes, the sealing strip can withstand long-term wind and sun exposure, temperature changes and vibrations during vehicle driving. The accelerated aging test verifies that the service life is prolonged by 2-3 times. The lip frame 222 is provided with an arc-shaped corner, the lip edge 223 is curved towards the lip frame 222, and the contact part of the sealing structure 22 and the side window glass 3 is provided with two sealing lips, one being the lip edge 223 and the other being the sponge bubble lip frame 222. This special design increases the contact area between the sealing mechanism 2 and the side window glass 3. When the side window glass 3 closes towards the sealing structure 22, the lip edge 223 and the lip frame 222 can tightly fit the side window glass 3, and when the side window glass 3 vibrates and displaces during vehicle driving, it can still maintain good sealing effect through elastic deformation.

[0039] Further, the mounting base 221 comprises: a base strip 2211 which is matched with the guide rail framework structure 21; a supporting part 2212 which is obliquely mounted on the base strip 2211, and which facilitates the shape support of the lip frame 222, so that the shape stability of the lip frame 222 is higher; a positioning part 2213 which is connected to the corner of one side of the base strip 2211; a clamping block 2214 which is connected to the edge line of the other side of the base strip 2211; a covering edge 2215 which is connected to the bottom of the clamping block 2214, and which facilitates the better cooperation between the guide rail framework structure 21 and the sealing structure 22, and effectively reduces the gap at the connection. The base strip 2211, the supporting part 2212 and the lip frame 222 form a parallelogram structure, which facilitates the elastic concave deformation when the side window glass 3 is extruded, so as to be in contact with the side window glass 3, and the obliquely designed lip edge 223 and the lip frame 222 with the corner structure, and the guide rail framework structure 21 which is adapted to the profile of the side window glass 3, effectively block the entry of external noise, dust, rainwater and cold and hot air.

[0040] The guide rail framework structure 21 comprises: a guide rail main body 211 which is mounted at the bottom of the mounting part 1; a plug-in part 212 which is mounted at the inner side of the guide rail main body 211, and which is plugged and matched with the positioning part 2213; and a buckling part 213 which is buckled and matched with the clamping block 2214, so as to facilitate the buckling and limiting of the position of one edge line of the base strip 2211, and facilitate the buckling and limiting of the position of the other edge line of the base strip 2211, so that the base strip 2211 can be closely attached to the guide rail main body 211, and the cooperation and installation between the sealing structure 22 and the guide rail framework structure 21 are more stable.

[0041] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
