Description

Technical Field

[0001] This utility model relates to the field of automotive parts and interior manufacturing technology, and in particular to high-smoothness roller shutter doors. Background Technology

[0002] With the increasing demand for diverse and customized storage space in automobiles, overhead storage boxes and other storage compartments have become standard equipment in commercial vehicles. Most overhead storage boxes and similar storage compartments on the market use lids that open and close by flipping up and down. During opening and closing, occupants often have to lean back to avoid this, which is detrimental to both operation and safety. To avoid these problems, some existing technologies use roller shutters instead of lids. However, these roller shutters are prone to friction noise, are not very flexible in opening and closing, and are prone to shifting. Summary of the Invention

[0003] The purpose of this utility model is to provide a high-smoothness roller shutter door that is equipped with a ball head pin to address the above-mentioned practical situation.

[0004] The technical solution adopted in this utility model is as follows: A high-smoothness roller shutter door includes a guide rail body, a roller shutter body, a handle, a decorative panel, a lock plate, a buffer head, a locking sleeve, a reinforcing plate, a ball pin, and a positioning post. The guide rail body comprises an integral guide rail frame, a baffle, a reinforcing rib, an outer frame, and an inner frame. The guide rail frame has a guide groove. The inner frame is connected to the middle of the upper and lower guide rail frames. The baffle is connected to one side of the upper and lower guide rail frames and to one side of the inner frame. The reinforcing rib is supported in the middle of the baffle. The outer frame is connected to the other side of the upper and lower guide rail frames, forming a doorway together with the inner frame and the upper and lower guide rail frames. The inner side of the outer frame and the other side of the inner frame are respectively provided with clamping posts and buffer posts. The buffer posts have mounting holes. The locking sleeve has a recessed clip and is fixed to the inner frame of the guide rail body. The lock plate is made of spring steel and has a clamp and a protruding clip, and is fixedly clamped to the clamping posts on the inner side of the outer frame and the other side of the inner frame of the guide rail body. The buffer head is made of rubber and is fixedly clamped to... The guide rail body has buffer posts in its mounting holes on the inner side of the outer frame and the other side of the inner frame. The guide rail body and all the components mounted on it together constitute the guide rail assembly. The roller blind body has a notched strip on one side of the curtain strip and a protruding strip on the other side. The curtain strips are assembled and movably connected to each other to form the roller blind body through their notched strips and protruding strips. Both ends of the curtain strips have slots, one end of which is a ball head and the other end has a clip. The ball head part has a step, and the ball head pin is fixed by the clip. The clips are inserted into the slots at both ends of the curtain strip slot, and the steps abut against the ends of the curtain strip slot. The reinforcing plate is provided with a second recessed strip, and the decorative panel is provided with a first recessed clip and a positioning hole. The handle and the reinforcing plate are respectively fixed on the inner and outer sides of the decorative panel. The positioning post is fixed on the reinforcing plate and positioned in the positioning hole of the decorative panel. The convex strip is movably connected to the second recessed strip of the reinforcing plate and assembled with the roller shutter body to form a roller shutter assembly. The roller shutter assembly is movably installed in the guide groove of the guide rail assembly through a ball head pin.

[0005] The ball head pin 9 is made of POM material or PA6-GF material.
