Abstract
Description
Technical Field
[0001] The utility model relates to the field of skylights, in particular to a high-sealing rear frame structure. Background Art
[0002] In the existing sunroof structure, the side guide rails are supported between the front and rear frames, and the side guide rails at the rear frame are mostly connected by screw locking. Even if they are locked with multiple screws, due to the same locking method, the threaded locking has the same risk of loosening when the vehicle is used for a long time. In addition, when the rear end face of the side guide rail is fitted with the rear end of the rear frame, there is still a small gap for water to fall through. The fallen water is easy to adhere to the gap between the end faces of the rear end face of the side guide rail due to tension. At the position of the rack hole of the mechanical group of the side guide rail, due to the sliding of the rack in the hole, it is easy to form a water absorption effect at the empty mouth of the rack hole of the mechanical group on the rear end face of the side guide rail, and water corrosion will enter the rack hole of the mechanical group, affecting the normal operation and service life of the rack. Summary of the invention
[0003] The utility model provides a high-sealing rear frame structure which has a simple structure and can effectively improve the sealing of the rear frame and the waterproofing of the side guide rails.
[0004] The technical solution adopted by the utility model is: a highly sealed rear frame structure, including a rear frame body, a glue injection groove for glue injection sealing and supporting the side guide rails is arranged on the front end surfaces of the folding feet at the left and right ends of the rear frame body, a drainage area is arranged on the folding feet, and the drainage area is externally connected to the drainage port, characterized in that: the frame body is respectively provided with more than four guide rail fixing holes for locking and connecting the guide rails on the inner side of the glue injection groove, the front and rear of the outer side of the glue injection groove, and the middle and rear side of the glue injection groove, the structures of the four guide rail fixing holes are screw holes or rivet holes, the two guide rail fixing holes at the front and rear of the outer side of the glue injection groove are holes of the same structure, the structures of the other two guide rail fixing holes are the same and different from the structures of the above two guide rail fixing holes, or the structures of the other two guide rail fixing holes are different; the folding feet are provided with anti-suction notches at the position of the driving rack holes of the mechanical group on the rear end faces of the corresponding side guide rails, and the anti-suction notches are connected to the drainage area below.
[0005] A sunshade driving motor mounting seat and an ECU card interface are arranged in the middle of the rear frame body.
[0006] A plurality of foreign matter blocking columns are arranged near the drainage outlet in the drainage area.
[0007] The anti-suction notch is provided with a sink groove on the end surface of the folded foot portion corresponding to the notch, and the sink groove is connected to the drainage area.
[0008] The gap of the sinking groove is arranged at the lower end of the side guide rail.
[0009] The beneficial effects of the utility model are:
[0010] 1. In the structural selection of the four guide rail fixing holes on the outside, rear and inside of the glue injection groove, the two outside ones are kept the same structure, and the other two can be the same or different. In this way, the four guide rail fixing holes are not exactly the same, which effectively avoids vibration loosening caused by the same thread locking structure when the vehicle is used, comprehensively improves the connection firmness with the side guide rails, ensures that the glue injection groove is crimped stably and firmly, and improves the sealing of the rear frame drainage area.
[0011] 2. An anti-suction notch is left between the mechanical group drive rack hole position on the rear end face of the side guide rail and the folding foot part of the rear frame body, which can effectively prevent the falling water from being sucked into the mechanical group drive rack hole on the rear end face of the side guide rail. The falling water can directly fall into the trough at the bottom of the period through the anti-suction notch and be discharged to the drainage area. After the foreign matter is blocked by the foreign matter blocking column, the water is discharged from the drain port. The gap of the trough part is placed at the lower end of the side guide rail, which can ensure that the falling water is fully poured into the trough. BRIEF DESCRIPTION OF THE DRAWINGS
