Description

Technical Field

[0001] The utility model belongs to the parts of the glass lifting device for automobile doors and windows, and particularly relates to a guide part for a window regulator. Background Art

[0002] A window regulator is a device for lifting the glass of an automobile door and window. According to the structure, the window regulator is divided into a cross-arm type window regulator and a rope-wheel type window regulator. Since the cross-arm type window regulator is not applicable to vehicles with a small glass bending radius and has a large requirement for the interior space structure of the vehicle, it no longer meets the customer's needs and has gradually withdrawn from the market. The rope-wheel type window regulator is applicable to glasses with various bending radii, is convenient for the overall vehicle styling, and has a small requirement for the interior space of the vehicle. It has been favored by major vehicle manufacturers, and most vehicle manufacturers now use the rope-wheel type electric window regulator.

[0003] The rope-wheel type window regulator is mainly composed of parts such as a guide rail, a guide part, a steel wire rope, a sleeve cap, a sheath, a sleeve, a reel seat, a wire reel, etc. Among them, the guide part is a key part for the transmission of the window regulator and plays a crucial role in the overall operation state of the window regulator. However, the current guide part has the following disadvantages:

[0004] (1). The original design of the guide part has an opening 9, as Figure 10 shown. After long-term use, the opening becomes larger, which will cause the gap between the guide part and the sleeve 8 to become larger and the shaking amount to also become larger, easily generating abnormal noises and increasing the system resistance, thereby affecting the use performance of the window regulator;

[0005] (2). The original design of the guide part has no limit in the Y direction at the place where the steel wire rope is installed 11, as Figure 11 shown. When the steel wire rope 6 and the guide part are assembled, during the assembly of the product, the steel wire rope often falls off from the limit 11 where the guide part is fitted, and rework is required, increasing the working hours and wasting labor costs;

[0006] (3). The original design of the guide part has a claw 10 structure, as Figure 10 , 11 , 12 shown. If the steel wire rope 6 is not installed in place, the clip often breaks, and the steel wire rope is easily detached from the L-shaped wire groove 14 during the operation of the window regulator, causing abnormal noises;

[0007] (4). The original design of the guide part cannot clamp the guide rail 7 in the guide rail installation groove 15, as Figure 13 shown.

[0008] (5). The original design of the guide part has a square hole 13 for installing the guide rail barb 16 on the extension plate 12, as Figure 12 , 14 shown. The guide rail 7 is processed with a barb 16 to be clamped with the square hole 13 of the guide part, increasing the manufacturing process and working hours of the guide rail. Summary of the invention

[0009] The utility model provides a glass lifter guide to solve the problems of the existing guide, such as the gap between the guide and the sleeve becomes larger, abnormal noise is generated, the wire rope is easy to fall off from the guide, the claw is easy to break, and the square hole on the extension plate is required to connect with the guide rail, which leads to increased process and working hours.

[0010] The technical solution adopted by the utility model is that the sleeve mounting hole of the guide member adopts a closed structure, one end of the wire rope limiting hole is connected to the sleeve mounting hole, and the other end is connected to the U-shaped wire groove, and there is a boss for clamping the guide rail in the guide rail mounting groove, and the straight edge located on one side of the guide rail is a flat plate structure.

[0011] The U-shaped wire groove of the utility model can store grease.

[0012] The straight edge of the utility model has no guide rail installation square hole and extension plate.

[0013] The advantages of the utility model are novel structure. The sleeve mounting hole of the guide part adopts a closed structure to increase the strength of the sleeve mouth, prevent the matching gap from becoming larger and the shaking amount from being large after long-term use, avoid the occurrence of abnormal noise and system resistance, and ensure the performance of the lifter; the wire rope limit hole can prevent the wire rope from falling off from the guide part mounting mouth after the wire rope and the guide part are assembled, and rework is avoided; the U-shaped wire groove can effectively store grease, so that the wire rope and the guide part are effectively lubricated; the mutual cooperation is tighter and more firm, and since the claws are eliminated, the claws can be prevented from breaking and the wire rope can be prevented from falling out, avoiding the occurrence of abnormal noise and functional failure of the lifter; the guide rail mounting groove has a boss for clamping the guide rail, which saves guide part materials, reduces the processing procedures and working hours of the guide rail, and reduces costs.

[0028] like Figure 1 , 2 As shown in Figures 5 and 6, the sleeve mounting hole 1 of the guide member adopts a closed structure, one end of the wire rope limiting hole 2 is connected to the sleeve mounting hole 1, and the other end is connected to the U-shaped wire groove 3, and there is a boss 4 for clamping the guide rail in the guide rail mounting groove, and the straight edge 5 located on one side of the guide rail is a flat plate structure.

[0029] like Figure 3 , 4 As shown, the U-shaped wire groove 3 can store grease.

[0030] like Figure 6 As shown, there are no guide rail mounting square holes and extension plates on the straight edge 5.

[0031] How it works

[0032] like Figure 7 , 8 As shown, the sleeve installation hole 1 is closed (no opening), which increases the strength of the guide member installation sleeve opening, avoids the gap between the sleeve 8 and the sleeve 8 becoming larger and the shaking amount becoming larger due to wear and tear, avoids the occurrence of abnormal noise and system resistance, and thus does not affect the performance of the lifter;

[0033] The wire rope limiting hole 2 can limit the position of the wire rope 6, so that the wire rope will not fall off from the wire rope installation hole of the guide member after the wire rope and the guide member are assembled, thus avoiding rework and saving work time;

[0034] The U-shaped wire duct 3 can not only increase the wire storage capacity of the wire duct to effectively store grease, so that the steel wire rope 6 and the guide are effectively lubricated, but also enable the steel wire rope and the guide to have more effective contact, resulting in closer and firmer cooperation between them. Thus, the clamping jaw 10 is eliminated, avoiding the fracture of the clamping jaw and the escape of the steel wire rope caused by the improper installation of the steel wire rope, which may lead to abnormal noise and functional failure of the lifter;

[0035] As Figure 9 shown, the boss 4 for clamping the guide rail in the guide rail installation groove can increase the effective contact area when assembled with the guide rail and generate a clamping force, making it not easy to fall off. Thus, the square hole 13 for installing the barb and the extension plate 12 designed for installing the barb are eliminated, saving materials. Correspondingly, the process of machining the barb 16 on the guide rail 7 is eliminated, reducing the working hours and saving costs.
