Description

Technical Field

[0001] The invention belongs to the technical field of automobile sunroof manufacturing and assembly, and in particular relates to an automobile sunroof glass slide rail. Background Art

[0002] The conventional existing automobile sunroof glass slide rail, as disclosed in the Chinese utility model (Announcement No. CN208842199), is provided with a rectangular notch at the bottom of the mechanical group running groove, a downward inclined inclined plate is provided on the side of the rectangular notch away from the drainage groove, the bottom of the inclined plate is connected to a horizontally arranged card plate A, a card plate B of the drainer is inserted along the upper surface of the card plate A so that the protrusion provided on the upper part of the card plate B fits into the rectangular notch, and then the drainer is fixed to the slide rail by screws on one side of the drainage groove.

[0003] The following problems exist in this type of drainer assembly and setting structure: 1. A groove must be opened at the bottom of the mechanical assembly running groove and a card plate structure must be set. After the drainer is inserted into the connecting slide rail through the card plate, it must be fastened and fixed with screws. The structural setting is complicated, the assembly operation is cumbersome, and the assembly efficiency is low. 2. The sealing of the assembly joint between the drainer and the drain groove is poor. When the screws become loose during the use of the car, the gap at the joint is easily enlarged, water leaks in the drain groove, and the sealing and anti-seepage ability is poor. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a car sunroof glass slide rail having a simple assembly structure and strong sealing and anti-seepage capabilities at the assembly joints between the drainer and the drain groove.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A drainer-equipped anti-water seepage automobile sunroof glass slide rail comprises a slide rail with a drainage groove and a mechanical group running groove arranged side by side, a mounting position formed at one end of the drainage groove and a drainer arranged in cooperation with the mounting position, a stopper is formed between the end face of the drainage groove and the outer wall of the mechanical group running groove, the drainer and the drainage groove are fastened and assembled at the bottom, a silicone sheet is arranged on the inner end face of the drainer, and when the drainer is fastened and assembled, the silicone sheet is squeezed and deformed as the drainer moves, forming a seal at the joint of the drainage groove and the drainer.

[0007] The present invention has the following beneficial effects:

[0008] By directly fastening and assembling the drainer at the bottom, there is no need to groove the bottom of the mechanical group running groove, which can save the slide rail processing process. The assembly setting structure is simple and efficient. When the drainer is assembled in the drainage groove, the silicone sheet set synchronously is squeezed and deformed on the drainer and the drainage groove to form a sealed and anti-seepage structure, thereby avoiding water leakage at the assembly joint between the drainer and the drainage groove.

[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical ideas claimed for protection of the present invention.

[0015] like Figures 1 to 4 The automobile sunroof glass slide rail shown includes a slide rail 1, on which a drainage groove 2 and a mechanical group running groove 3 are arranged side by side, one end of the drainage groove 2 is shorter than the end surface of the mechanical group running groove 3 to form a mounting position 20, and a stop platform 21 is formed between the end surface of the drainage groove 2 and the outer wall of the mechanical group running groove 3, and the drainer 4 corresponds to the mounting position 20 and is arranged in cooperation with the mounting position 20.

[0016] The first fastening holes 22 are distributed at the bottom of the drain groove 2. The first fastening holes 22 extend along the length direction of the drain groove 2 at the bottom of the drain groove 2 and are integrally formed with the drain groove 2. They can be extruded as a whole with the slide rail 1, which is convenient for production and improves production efficiency, and saves the drilling process of the first fastening holes 22. The second fastening holes 41 are distributed at the bottom of the drainer 4. When the drainer 4 is arranged in the installation position 20, the second fastening holes 41 correspond to the first fastening holes 22, and the end of the second fastening hole 41 protrudes toward the inner end surface of the drainer 4 to form a convex seat 42.

[0017] A silicone sheet 5 is arranged between the end face of the drain groove 2 and the inner end face of the drainer 4, and embedded holes 51 are arranged at the bottom of the silicone sheet 5. The hole depth of the embedded holes 51 is longer than the length of the protrusion 42, that is, the thickness of the silicone sheet 5 is set to be greater than the length of the protrusion 42. The silicone sheet 5 is embedded in the protrusion 42 through the embedded holes 51. During assembly, self-tapping screws are tapped in turn on the inner walls of the second fastening holes 41 and the first fastening holes 22 to fasten the drainer 4 to the installation position 20. The fastening and assembly connection strength of the drainer 4 is high and it is not easy to loosen due to the bumps of the car.

[0018] Since the thickness of the silicone sheet 5 is greater than the length of the protrusion 42, after the silicone sheet 5 is embedded in the protrusion 42 through the embedding hole 51, when the drainer 4 is tightened with the self-tapping screw, the drainer 4 moves toward the end face of the drain groove 2 and squeezes the silicone sheet 5 toward the end face of the drain groove 2 until the protrusion 42 abuts against the end face of the drain groove 2. While the drainer 4 is fastened and assembled in the drain groove 2, the silicone sheet 5 is squeezed and deformed and assembled between the end face of the drain groove 2 and the inner end face of the drainer 4, forming a seal at the joint between the drain groove 2 and the drainer 4, effectively preventing water from leaking from the joint between the drain groove 2 and the drainer 4, improving the installation and assembly efficiency of the drainer 4, simplifying the assembly and setting structure of the drainer 4, and improving the sealing and anti-water seepage ability of the drainer 4.

[0019] In specific implementation, the second fastening hole 41 can also be set as a through hole for only the self-tapping screw to pass through, so that the self-tapping screw can directly pass through the second fastening hole 41 and then tap and fasten on the first fastening hole 22. The fastening stability of the drainer 4 can also meet the assembly requirements of the drainer 4, and the tapping operation intensity of the self-tapping screw can be reduced.

[0020] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the present invention.
