Description

Technical Field

[0001] This utility model relates to components of automotive window regulators, and more particularly to a window regulator bracket structure. Background Technology

[0002] A window regulator is a device for raising and lowering car doors and windows. Most window regulators currently use a mechanically driven rope-wheel structure. A window regulator consists of a motor, guide rails, steel cables, a glass support, and a reel seat. Its main working principle is that the motor drives the tightening or releasing of the steel cables, which in turn moves the glass support up and down along the guide rails, thus raising and lowering the window. The glass support primarily holds the glass in place and connects to the transmission mechanism to transmit power, thereby enabling the window to be raised or lowered.

[0003] The original glass bracket cable exit method was a cross-type with a thin insulating baffle in the middle. Figure 3 , 4 As shown in Figure 5, after the lift has been in operation or undergone durability testing, cables 7 and 8 are prone to overlap, causing abnormal noise and wear on the cables. The original two hanging slots 2 and 4 were arranged in parallel, ensuring they were oriented and identical in shape. Springs 3 were also installed at the joints of cables 1 and 2. During production, cables 1 and 2 were easily mis-attached, leading to lifting failures and a high probability of rework and scrap. The buffer block 6 on the original bracket was assembled later and is at risk of falling off after durability testing, causing abnormal noise at the lower support point of the bracket, resulting in customer complaints and reduced satisfaction. Summary of the Invention

[0004] This utility model provides a glass lifter bracket structure to solve the existing problems of abnormal noise caused by friction of cable overlap due to wear and thinning of the baffle or reduction of cable tension, easy mis-hanging and reverse installation of cables, and drop of buffer blocks.

[0005] The technical solution adopted by this utility model is as follows: a bracket body, a first hanging groove, a first cable connector spring, a second hanging groove, an isolation groove, and a buffer block. The first hanging groove and the second hanging groove on the bracket body are arranged opposite to each other. The first cable connector spring is installed in the first hanging groove. The isolation groove is located at the front end of the second hanging groove in the direction of the cable outlet. The buffer block is injection molded into the bracket body.

[0006] The width of the isolation groove is greater than the diameter of the steel wire rope in the cable.

[0007] The inner wall of the isolation trough does not come into contact with the steel wire rope inside.

[0008] The cable tray 1 and cable tray 2 on the bracket body are arranged opposite to each other. Cable 1 installed in cable tray 1 passes through cable joint spring 1 and exits from the direction of cable tray 2. Cable 2 installed in cable tray 2 passes through isolation cable tray and exits from cable tray 1.

[0009] The advantages of this invention are its novel structure. It solves the problems of abnormal noise and breakage of the glass support during operation caused by overlapping of two cables through the use of an isolation cable groove; it solves the problems of incorrect cable installation leading to lifting failure and rework by using oppositely arranged cable grooves; and it solves the problem of abnormal noise at the lower support point caused by the original buffer block falling off during use by using an integrated buffer block. This invention improves the noise reduction, fatigue resistance, wear resistance, and durability of the overall glass lifter structure, maximizing user experience, extending service life, reducing the probability of failure, and improving the structural quality of the glass lifter.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0017] See Figure 1 , 2The bracket body 1, cable hanging groove 1 2, cable connector spring 1 3, cable hanging groove 2 4, isolation cable groove 5, and buffer block 6 are provided. The cable hanging groove 1 2 and cable hanging groove 2 4 on the bracket body 1 are arranged opposite to each other. The cable connector spring 1 3 is installed in the cable hanging groove 1 2. The isolation cable groove 5 is located at the front end of the cable hanging groove 2 4 in the cable outlet direction. The buffer block 6 is injection molded into the bracket body 1.

[0018] See Figure 1 The width of the isolation groove 5 is greater than the diameter of the steel wire rope in the cable.

[0019] See Figure 1 The inner wall of the isolation groove 5 does not contact the steel wire rope therein.

[0020] See Figure 2 The cable tray 1 and cable tray 2 are arranged opposite to each other on the bracket body 1. Cable 7 installed in cable tray 1 passes through cable joint spring 3 and exits from the direction of cable tray 2 4. Cable 8 installed in cable tray 2 passes through isolation cable tray 5 and exits from the direction of cable tray 1 3.

[0021] Working principle

[0022] The existing isolation baffle 9 structure at the cable exit intersection of the bracket is replaced with an isolation groove 5 structure. The width of the isolation groove 5 is made larger than the diameter of the steel wire rope in the cable, and its inner wall does not contact the cable wire rope. This prevents the isolation baffle from wearing down or the cable tension from decreasing after operation or durability, thus avoiding overlap between the two cables and preventing abnormal noise caused by friction. It also reduces wear between the two cables, extending the product's service life.

[0023] The structure of the cable trays was modified, changing the original cable trays with the same direction and shape to cable trays with opposite directions and different shapes. At the same time, the spring of one of the cable joints was removed, which can prevent the two cables from being installed incorrectly or in reverse, effectively avoiding lifting failure caused by this. It also reduces the probability of rework and scrap and investment costs, and enhances the market competitiveness of the product.

[0024] The original buffer block installed at the rear of the bracket was replaced with a buffer block integrated with the bracket. This avoids the problem of the buffer block falling off during use, prevents abnormal noise at the lower support point of the bracket caused by the buffer block falling off, and avoids customer complaints, thus improving customer satisfaction.

[0025] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and the inventive concept of the present invention within the scope of the technical concept disclosed in the present invention shall all fall within the scope of protection of the present invention.

[0026] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
