Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to a slider assembly for a window regulator. Background Technology

[0002] A window regulator is a mechanism used for raising and lowering car windows. It uses a slider to move the glass up and down, and a glass clamp is mounted on the slider to hold the glass in place. Currently, the slider and glass clamp are fixed together with bolts. For example, the window regulator slider assembly and window regulator disclosed in Chinese patent literature [Application No. 201520396948.3] discloses that the glass bracket, movable parts, and fixed parts are respectively connected by bolts, thus preventing relative movement between the window glass and the movable parts and avoiding abnormal noise during window raising and lowering. Currently, the sliders are all made of plastic, and the bolts pass through the slider. Due to the insufficient hardness of the plastic material and the difficulty in controlling the precision of the manufacturing process, the contact surface between the bolt and the slider cannot be concentric. This leads to inconsistent installation accuracy of the glass clamp, and after prolonged use, factors such as vehicle vibration can cause the bolts to loosen relative to the slider, resulting in abnormal noise during window raising and lowering. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a slider assembly for a glass lifter. The technical problem solved by this invention is to improve the installation accuracy and strength of the glass clamp.

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

[0005] A slider assembly for a glass lifter includes a slider and two glass clamps, characterized in that two metal bushings are fixed on the slider, the outer periphery of the metal bushings is provided with ribs, the ribs are located in the middle of the metal bushings, the ribs are embedded in the slider, and the two glass clamps are respectively fixed to the two metal bushings by fixing bolts.

[0006] The metal bushing is made of high-hardness material with high machining precision, ensuring concentricity between the contact surfaces of the bolt and the metal bushing. This improves the bolt's fixing accuracy and prevents loosening after prolonged use, thus enhancing the installation accuracy and stability of the glass clamp. This ensures precise positioning of the car window glass, avoids abnormal noises after long-term use, and improves the overall product quality of the window regulator. The metal bushing is fixed to the slider by ribs, preventing the metal bushing from falling off the slider and ensuring fixing strength and accuracy.

[0007] In the above slider assembly for a window regulator, the metal bushing and the slider are fixed by an insert molding process. The metal bushing is placed into the mold for the slider to achieve fixation between the metal bushing and the slider, and the protruding ribs of the metal bushing are directly embedded into the slider, ensuring the fixing strength and precision between the metal bushing and the slider.

[0008] In the above slider assembly for a window regulator, the metal bushing is made of aluminum alloy or iron-carbon alloy.

[0009] In the above slider assembly for a window regulator, the two metal bushings are a circular metal bushing and a waist-shaped metal bushing respectively. A fixing bolt passes through the inner hole of the circular metal bushing to accurately position the corresponding glass clamp, and the fixing bolt passes through the strip-shaped hole of the waist-shaped metal bushing to adjust the relative position of the corresponding glass clamp, such that the fixing position between the glass and the glass clamp can be flexibly adjusted via the waist-shaped metal bushing during installation.

[0010] In the above slider assembly for a window regulator, mounting portions are provided on both sides of the slider, the metal bushing is fixed to the mounting portions, a first fitting flat surface is provided on each of the mounting portions, the glass clamp comprises a U-shaped main body and a connecting plate portion located on the lower side of the main body, a second fitting flat surface is provided on one side of the connecting plate portion, the second fitting flat surface protrudes from one side surface of the main body, and the first fitting flat surface and the second fitting flat surface are abutted against each other in a fitted manner when the slider and the glass clamp are fixed. This structure enables stable fitting and fixation between the slider and the glass clamp.

[0011] In the above slider assembly for a window regulator, a serrated nut is fixed on the connecting plate portion, and the fixing bolt is fixedly connected with the serrated nut.

[0012] In the above slider assembly for a window regulator, the glass clamp and the serrated nut are fixed by an insert molding process. The serrated nut is placed into the mold for the glass clamp to achieve fixation between the glass clamp and the serrated nut, and the retaining teeth on the outer ring of the serrated nut are directly embedded into the glass clamp, ensuring the fixing strength and precision between the glass clamp and the serrated nut.

[0013] In the above slider assembly for a window regulator, a plurality of anti-slip grooves are vertically formed on the inner wall of the U-shaped groove of the main body. The anti-slip grooves enable firm connection between the glass and the main body.

[0014] In the above slider assembly for a window regulator, the slider is in an inverted triangular shape, the mounting portions of the slider are located at two corners on the upper side of the slider, a main reinforcing rib in a shape of the Chinese character "ji" (several) is arranged on the slider, and two end portions of the main reinforcing rib extend to the lower sides of the mounting portions respectively. This structure ensures that the slider structure can bear the weight of the glass.

[0015] Compared with the prior art, the slider assembly for the window regulator has the advantage of improving the mounting precision and strength of the glass clamp. Attached Figure Description

Specifically, the metal bush and the slider 1 are fixed by an insert molding process, and the metal bush is placed into the mold of the slider 1 to realize the fixation of the metal bush and the slider 1. The metal bush is made of aluminum alloy or iron-carbon alloy. As a preference, the metal bush is made of aluminum alloy, which is low in cost, sufficient in hardness and convenient in processing. The two glass clamps 2 are respectively fixed to the two metal bushes by fixing bolts 4. When the fixing bolt 4 is mated with the circular metal bush 31, it forms a tight fit with the circular hole of the circular metal bush 31. When the fixing bolt 4 is mated with the waist-shaped metal bush 32, the diameter of the fixing bolt 4 matches the width of the waist-shaped hole of the waist-shaped metal bush 32, and the fixing bolt 4 can move along the length direction of the waist-shaped hole, so as to adjust the position of the corresponding glass clamp 2 and facilitate the installation of the glass.
