Description

Technical Field

[0001] The invention relates to the technical field of sunshade curtains, and in particular to an electric sunshade curtain assembly structure with a self-adjusting structure. Background Art

[0002] Cars are an important means of transportation for people to travel, providing convenience for people's travel. Since cars are often outdoors, when the sun shines into the cabin through the car windows, it will make the interior of the car hot, and the strong light will also cause inconvenience to the driver. In order to block the sunlight shining into the cabin through the car windows, people have made car sunshade roller blinds. When the sunshade roller blinds are not in use, the curtains are rotated and rolled up through the shaft. When it is necessary to block the sunlight, pull the curtains, the curtains drive the shaft to rotate, and the curtains are unrolled from the roller; when it is not necessary to block the sunlight, the shaft is driven to rotate, and the shaft rolls up the curtains, so that the curtains cannot block the car windows, making it convenient for people to drive the vehicle. Due to the limited space inside the car and the different sizes of the interior space of different cars, it is often necessary to flexibly adjust the position and angle of the sunshade when installing and using the sunshade. Among the existing car sunshades on the market, there is a type of sunshade that is installed inside the car by hanging it on the sun visor, but the position of the sunshade inside the car cannot be adjusted, making it difficult to adjust the position of the sunshade. When the angle of the sunshade needs to be adjusted, the sunshade can only be driven to rotate by rotating the sun visor, so that the angle between the sun visor and the sunshade is limited. Therefore, we redesigned an electric sunshade assembly structure with a self-adjusting structure. Summary of the invention

[0003] The object of the present invention is to provide an electric sunshade assembly structure with a self-adjusting structure.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an electric sunshade curtain assembly structure with a self-adjusting structure, comprising a frame assembly, a pull rope is arranged inside one side of the frame assembly, a supporting pulley assembly is arranged on one side of the pull rope, a steering adjustment pulley assembly is arranged inside the top end of one side of the frame assembly close to the supporting pulley assembly, an auxiliary wire wheel assembly is arranged inside the top end of one side of the frame assembly, a driving wire wheel is movably installed on one side of the frame assembly close to the auxiliary wire wheel assembly, a driving motor is arranged on the top end of the frame assembly close to the driving wire wheel, a roller curtain assembly is rotatably connected to one side of the driving wire wheel, a guide rail is fixedly installed on one side of the supporting pulley assembly, and a mounting support is fixedly installed on the bottom end of the frame assembly close to the auxiliary wire wheel assembly.

[0009] Preferably, the connection relationship between the steering pulley and the pull rope is a transmission connection, and the connection relationship between the pulley support seat and the frame assembly is a sliding connection.

[0010] Preferably, the auxiliary wire wheel combination includes an auxiliary wire wheel, a pull rope support wheel, and an auxiliary wire wheel shaft. A first groove is opened on one side surface of the auxiliary wire wheel, and the pull rope is located inside the first groove. The roller blind combination includes a handle slider, an inner tube, and an inner tube connecting sleeve.

[0013] Compared with the related art, the electric sunshade assembly structure with a self-adjusting structure provided by the present invention has the following beneficial effects:

[0014] 1. The present invention provides an electric sunshade assembly structure with a self-adjusting structure, which is composed of a fixed seat, an adjusting spring, a pulley support seat, and a steering pulley by setting a steering adjustment pulley group.

The width of this pull rope groove is equal to the diameter of the pull rope, and the depth is greater than times the diameter of the pull rope, which can increase sufficient friction resistance. The pull rope passes through the pull rope groove and is alternately wound between the driving wire wheel and the auxiliary wire wheel. The auxiliary wire wheel combination is composed of an auxiliary wire wheel, a pull rope support wheel, and an auxiliary wire wheel shaft. The auxiliary wire wheel group is fixed to the mounting support through the auxiliary wire wheel shaft. And the auxiliary wire wheel combination rotates on the mounting support through the auxiliary wire wheel shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] 2. This patent is applicable to curved arc guide rail systems.

[0037] 3. This patent is applicable to a pull-cord type electric sunshade structure in which the pull cord can be automatically adjusted.

[0038] 4. By arranging the steering adjustment pulley set 4 on the guide rail 9, the length change of the pull rope 2 after durability can be effectively adjusted by adjusting the expansion and contraction of the spring 4.3. Figure 4 )

[0039] 5. The steering adjustment pulley block 4 is composed of a fixed seat 4.4, an adjustment spring 4.3, a pulley support seat 4.1, and a steering pulley 4.1. The steering pulley block rigidly fixes the fixed seat 4.4 to the guide rail 9 through a fixed connector 12, and the adjustment spring 4.3 connects the pulley support seat 4.1 and the fixed seat 4.4. The pulley support seat 4.1 is clamped in the slide groove 9.1 of the guide rail 9 through the feature 4.1.2, so that the pulley support seat 4.1 can only slide forward and backward in the slide groove 9.1 of the guide rail 9. The pull rope 2 slides in the steering pulley 4.2 and exerts pressure on the steering pulley 4.2 backward. The pressure is transmitted to the pulley support seat 4.1 through the steering pulley 4.2, and then transmitted to the adjustment spring 4.3. Due to the reaction force of the adjustment spring 4.3, the two are kept balanced. When the pull rope 2 becomes longer and loose due to durability, the reaction force of the adjustment spring 4.3 will push the pulley support seat 4.1 forward, thereby tightening the pull rope 2 again. Figure 4 and Figure 6 )

[0040] 6. The function of the support pulley block 3 in this system is to support the pull rope 2 so that the pull rope 2 is isolated from the guide rail 9 to avoid direct friction between the two. A corresponding number of support pulley blocks 3 are arranged in the guide rail 9 according to the curvature and length of the guide rail 9. The support pulley block 3 is composed of a mounting base 3.1 and a pulley 3.2 (such as Figure 3 ).

The system is designed to support the pulley block 3 and the guide rail 9 matching structure (such as Figure 9 ), the support pulley block 3 and the guide rail 9 are designed to be fixed by a clamping structure, which is fixed by the clamping structure on the mounting base and the slide groove 9.1 on the guide rail 9, thereby preventing the support pulley block 3 from escaping from the guide rail. Two pulleys 3.2 are designed in the support pulley block 3, and the pull rope 2 slides in the pulleys 3.2. The pulleys 3.2 are arranged in a high and low arrangement to avoid the sliding space of the pull handle slider 8.1. (As shown in FIG. Figure 9 )

[0043] 9. In the friction reel system, the driving reel 6 is designed with different numbers of rope grooves 6.1, and the auxiliary reel 5.1 is also designed with different numbers of rope grooves 5.4 for the rope 2 to slide during the process. The width of the rope groove is equal to the rope diameter, and the depth is greater than 1.5 times the rope diameter, which can increase sufficient friction resistance. The rope 2 is alternately wound between the driving reel 6 and the auxiliary reel 5 through the rope grooves 6.1 and 5.4. (e.g. Figure 7 , Figure 10 , Figure 5 (shown)
