Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtain accessories, in particular to a rolling curtain track profile for an automobile. Background Art

[0002] Electric roller blinds are electric roller blinds that use tubular motors as power. They are easy to operate and work quietly and smoothly. With the development of roller blind technology, the development of car roller blinds is also getting faster and faster. Car roller blinds can block sunlight, protect privacy, and bring better experience to passengers. Roller blind track profiles are one of the important accessories of roller blinds. They mainly guide the movement of the rod and ensure the stability of the roller blinds.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the existing track profiles are relatively simple in structure and single in function when in use, and can only play a simple guiding role. When the roller blind guide rod is used for a long time, the wear between the guide rod roller and the guide rail increases, and the guide rod is prone to offset. There is a lack of a stable resistance reduction structure to extend the service life of the roller blind. Therefore, an automobile roller blind track profile is proposed to solve the above-mentioned problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 4 As shown, a rolling shutter track profile for an automobile comprises a guide rail body 1, a guide groove 2 is provided in the center of the guide rail body 1, and a guide bar 1 3 and a guide bar 2 4 are respectively fixedly connected to the upper and lower sides of the guide rail body 1, a movable groove 5 is provided in the rear side of the guide rail body 1, a resistance reducing ring 6 is movably connected in the guide groove 2, an anti-slip ring 7 is fixedly connected to the rear side of the resistance reducing ring 6, a resistance reducing groove 8 is provided in the center of the outer side of the resistance reducing ring 6, a clamping groove 9 is provided in the interior of the resistance reducing ring 6, and a group of limiting fixing mechanisms 10 are arranged on the front side of the resistance reducing ring 6, and two guide rail bodies 1 are first symmetrically installed in the interior of the automobile.

[0024] Furthermore, in order to improve the connection stability between the guide rod and the resistance reduction ring 6 and avoid the roller blind guide rod from falling off, a limiting fixing mechanism 10 is provided, and the limiting fixing mechanism 10 includes a bonding plate 11, one end of the bonding plate 11 is fixedly connected to a limiting plate 12, and the lower end of the limiting plate 12 is respectively provided with an extrusion surface 13 and a limiting surface 14 on the front and rear sides, and the upper end of the limiting plate 12 is fixedly connected with a sliding block 15 on the rear side, and a support rod 16 is provided inside the sliding block 15, and a return spring 17 is provided on the outer side of the support rod 16.

[0025] Furthermore, when the resistance reducing ring 6 moves, it drives the anti-slip ring 7 to move inside the movable groove 5, thereby improving the movement stability of the resistance reducing ring 6. One end of the anti-slip ring 7 is located inside the movable groove 5, and the anti-slip ring 7 is movably connected to the movable groove 5.

[0026] Furthermore, the cross-section of the resistance reduction groove 8 is arranged in an arc shape, and the outer side of the resistance reduction groove 8 is in contact with the bottom surface of the guide bar 1 3 and the top surface of the guide bar 2 4. When the automobile roller shutter is started, the roller shutter guide rod drives the resistance reduction ring 6 to move inside the guide groove 2. At this time, due to the friction between the resistance reduction groove 8 and the guide bar 1 3 and the guide bar 2 4, the resistance reduction ring 6 drives the guide rod to rotate synchronously, thereby reducing its moving friction.

[0027] Furthermore, when the guide rod enters the clamping groove 9, one side of the guide rod is clamped and limited by the bonding plate 11, and the inner and outer sides of the bonding plate 11 are both arc-shaped. The bonding plate 11 is located inside the clamping groove 9, and the outer side of the bonding plate 11 is bonded to the inner surface of the clamping groove 9.

[0028] Furthermore, the limit plate 12 is located at the outside of the clamping groove 9, the extrusion surface 13 is arranged in an inclined shape, the limit surface 14 is arranged in a vertical shape, and the limit surface 14 is in contact with the outer side of the resistance reduction ring 6. During the movement of the guide rod, it first contacts the extrusion surface 13, and the limit plate 12 is moved outward through the extrusion surface 13 until one end of the guide rod completely enters the clamping groove 9, and the limit plate 12 is reset. At this time, the limit surface 14 limits the vertical surface of one end of the guide rod to prevent it from falling off.

[0029] Furthermore, when the limit plate 12 moves, it drives the sliding block 15 to move synchronously, and the sliding block 15 ensures the movement stability of the limit plate 12. The sliding block 15 is located inside the drag reduction ring 6, and the sliding block 15 is slidably connected to the drag reduction ring 6, the support rod 16 is fixedly connected to the drag reduction ring 6, and the two ends of the reset spring 17 are respectively fixedly connected to the sliding block 15 and the inner surface of the drag reduction ring 6.

[0030] Working principle: The main part of the roller blind guide rail profile is composed of the guide rail body 1, the resistance reduction ring 6 and the limit fixing mechanism 10. First, the two guide rail bodies 1 are symmetrically installed inside the car, and then the roller blind guide rod is moved so that its two ends are connected to the two resistance reduction rings 6 respectively. During the movement of the guide rod, it first contacts the extrusion surface 13, and the limit plate 12 moves outward through the extrusion surface 13 until one end of the guide rod completely enters the clamping groove 9. Under the action of the reset spring 17, the limit plate 12 is reset. At this time, the laminating plate 11 is pressed against one end of the guide rod. The side is clamped and limited, and the limiting surface 14 limits the vertical surface of one end of the guide rod to prevent it from falling off. After the car roller shutter is started, the roller shutter guide rod drives the resistance reduction ring 6 to move inside the guide groove 2. At this time, due to the friction between the resistance reduction groove 8 and the guide strip 1 3 and the guide strip 2 4, the resistance reduction ring 6 drives the guide rod to rotate synchronously to reduce its moving friction, and when the resistance reduction ring 6 moves, it drives the anti-slip ring 7 to move inside the movable groove 5, thereby improving the moving stability of the resistance reduction ring 6, avoiding the deviation problem of the guide rod, and ensuring the stable retraction and extension of the roller shutter.
