Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to a guide structure for the steel wire rope in a window regulator. Background Technology

[0002] As competition intensifies in the automotive industry and cost and quality control become increasingly stringent, the automotive parts manufacturing industry faces unprecedented pressure. Single-rail cable-driven power windows are the structure used to raise and lower car windows. With the increasing curvature of car bodies and windows, the power window guide rail is generally designed with an arc shape. Without a guiding structure to restrain the steel cable during operation, the middle section will sway significantly, causing abnormal noise. Therefore, current power windows incorporate guiding structures. For example, a steel cable pre-tensioning device for a power window disclosed in Chinese patent literature [Authorization Announcement No. CN216476897U] includes a guide block that can be fixed on the power window guide rail and a bracket for mounting the guide block. An adjusting component is provided between the guide block and the bracket to drive the guide block to move relative to the bracket. The guide block has an abutment guide surface for guiding the steel cable to slide. In this patent, the steel cable is guided and limited through a through hole formed by the left and right arms. However, the through hole is relatively short, resulting in a short guiding and limiting length for the steel cable, which cannot completely suppress the swaying of the steel cable and still produces abnormal noise. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a guiding structure for the steel wire rope in a glass lifter. The technical problem solved by this invention is to guide and limit the movement of a longer section of steel wire rope.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A guide structure for a steel wire rope in a glass lifter, the glass lifter including a guide rail, characterized in that the guide structure includes a fixed seat and a guide member, the fixed seat is fixedly installed in the middle section of the guide rail, the guide member includes a main body, a main limiting hook and two secondary limiting hooks, the main body and the fixed seat are fixedly connected by a snap-fit ​​structure, the two secondary limiting hooks are respectively located on both sides of the main limiting hook, each secondary limiting hook and the main limiting hook are spaced apart by a distance, the main limiting hook and the two secondary limiting hooks are all L-shaped, the orientation of the first notch formed between the main limiting hook and the main body is opposite to the orientation of the second notch formed between the secondary limiting hook and the main body, the first notch and the second notch are connected along a straight line to form a guide channel.

[0006] The direction in which notches one and two are connected in a straight line is the direction in which the wire rope passes through. The guide channel is limited and sealed by the main limit hook and the secondary limit hook. The middle section of the wire rope passes through the guide channel. The guide channel formed by the cooperation of the main limit hook and the two secondary limit hooks can limit the wire rope passing through, so as to avoid the middle section of the wire rope from jumping violently and causing impact noise when the window lift is running. The gap between the main limit hook and the secondary limit hook can further increase the length of the guide channel, which can also guide and limit the longer part of the wire rope, ensuring the stability of the middle section of the wire rope and avoiding abnormal noise.

[0007] In the aforementioned glass lifter's wire rope guide structure, the main limiting hook includes a main connecting section and a main bending section, and the secondary limiting hook includes a secondary connecting section and a secondary bending section. The main bending section and the secondary bending section partially overlap in the straight direction of the guide channel, and the inner side of the secondary bending section is located outside the inner side of the main bending section. This structure ensures that the guide channel is closed on all sides in the wire rope's path, while also preventing the wire rope from contacting the secondary bending section of the secondary limiting hook when the jump amplitude is small. This results in a guide channel that is narrow in the middle and wide at both ends, reducing the contact area with the wire rope while ensuring a long guide channel.

[0008] In the aforementioned glass lifter, the guide structure of the steel wire rope has a guide slope on the inner side of the end of the secondary bending section, and the outer end of the guide slope is located on the outer side of the outer side of the main connecting section.

[0009] In the aforementioned glass lifter, the guide structure of the steel wire rope has a gap of two between the end of the secondary connecting section and the end of the main bending section.

[0010] In the aforementioned glass lifter's wire rope guide structure, the main body has a protrusion opposite to the main limiting hook. The side of the protrusion facing the main limiting hook is a protruding limiting arc surface, and clearance arc surfaces are provided on both sides of the limiting arc surface. The protrusion is directly opposite the main limiting hook, preventing the wire rope from contacting the part of the main body directly opposite the secondary limiting hook. The clearance arc surfaces on the protrusion also prevent contact with the wire rope. The protruding limiting arc surfaces reduce the contact area between the wire rope and the protrusion, thereby reducing the resistance generated when in contact with the wire rope.

[0011] In the aforementioned glass lifter's wire rope guide structure, the outer periphery of the back side of the main limiting hook is provided with a thickened portion. This thickened portion increases the structural strength of the main limiting hook.

[0012] In the aforementioned guide structure for the steel wire rope in the glass lifter, the back of the main body is provided with a slot, and the main body also has two buckles located outside the slot. The fixing seat is plate-shaped, and two locking holes are provided on the fixing seat. The fixing seat is inserted into the slot, and the two buckles are respectively engaged in the locking holes. Through the cooperation of the buckles and locking holes, the fixing seat is fixed in the slot, realizing the fixed installation of the fixing seat and the guide component, and enabling the quick installation of the guide component.

[0013] Compared with existing technologies, the guide structure of the steel wire rope in this glass lifter has the advantages of being able to guide and limit the longer section of the steel wire rope, ensuring the stability of the middle section of the steel wire rope and avoiding abnormal noise.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6As shown, the glass lifter includes a guide rail 1 and two pulleys 11. A steel wire rope 12 is wound between the two pulleys 11, and the rotation of the steel wire rope 12 is achieved by a motor driving one of the pulleys 11. The guide structure includes a fixed base 2 and a guide member 3. The fixed base 2 is fixedly installed in the middle section of the guide rail 1. The guide member 3 includes a main body 31, a main limit hook 32, and two secondary limit hooks 33. The main body 31 is fixedly connected to the fixed base 2 by a snap-fit ​​structure 312. The two secondary limit hooks 33 are respectively located at the main limit hook 31. On both sides of the main limit hook 32, there is a gap 35 between the two secondary limit hooks 33 and the main limit hook 32. The main limit hook 32 and the two secondary limit hooks 33 are all L-shaped. The orientation of the notch 324 formed between the main limit hook 32 and the main body 31 is opposite to the orientation of the notch 334 formed between the secondary limit hooks 33 and the main body 31. The notches 324 and 334 are connected in a straight line to form a closed guide channel 36. The middle section of the wire rope 12 passes through the guide channel 36. The main limit hook 32 includes a main connecting section 321 and a main bending section 322. A thickened part 323 is provided on the outer periphery of the back of the main limit hook 32. The secondary limit hook 33 includes a secondary connecting section 331 and a secondary bending section 332. The main bending section 322 and the secondary bending section 332 partially overlap in the straight direction of the guide channel 36, and the inner side of the secondary bending section 332 is located outside the inner side of the main bending section 322. This structure, which makes the guide channel 36 narrow in the middle and wide at both ends, reduces the contact area with the wire rope 12 while ensuring that the guide channel 36 is long.

[0023] The inner side of the end of the secondary bending section 332 is provided with a guide slope 333, and the outer end of the guide slope 333 is located outside the outer side of the main connecting section 321. A gap 37 is provided between the end of the secondary connecting section 331 and the end of the main bending section 322. During installation, the middle section of the wire rope 12 is directly pressed in along the guide slope. The middle section of the wire rope 12 first gets stuck into the outer end of the guide slope 333, and then the deformation of the secondary bending section 332 allows the wire rope 12 to enter the guide channel 36, which is convenient for installation.

[0024] The main body 31 has a protrusion 34 opposite to the main limiting hook 32. The side of the protrusion 34 facing the main limiting hook 32 is a protruding limiting arc surface 341. On both sides of the limiting arc surface 341, there are relief arc surfaces 342. The protrusion 34 is directly opposite the main limiting hook 32, which avoids the wire rope 12 from contacting the part of the main body 31 that is directly opposite the secondary limiting hook 33. The relief arc surfaces 342 on the protrusion 34 also prevent contact with the wire rope 12. The protruding limiting arc surfaces 341 reduce the contact area between the wire rope 12 and the protrusion 34, thereby reducing the resistance generated when in contact with the wire rope 12.

[0025] The back of the main body 31 is provided with a slot 311, and the main body 31 is also provided with two buckles 312 located outside the slot 311. The fixing seat 2 is plate-shaped and has three parallel reinforcing ribs 21. The fixing seat 2 is fixed to the guide rail 1 by bolts. The fixing seat 2 has two locking holes 22. The fixing seat 2 is inserted into the slot 311 and the two buckles 312 are respectively engaged in the locking holes 22. The fixing seat 2 is fixed in the slot 311 by the cooperation of the buckles 312 and the locking holes 22.

[0026] The guide channel 36 formed by the cooperation of the main limit hook 32 and the two auxiliary limit hooks 33 can guide and limit the steel wire rope 12 passing through, so as to avoid the violent jumping of the middle section of the steel wire rope 12 during the operation of the window lift and the resulting impact noise.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
