[0002] Traditional window regulator motor wheel covers do not have a buffer structure. The guide tube that is fitted to the motor wheel cover is cylindrical and has a round hole. As the spring extends and then tightens, the guide tube will hit the outlet of the motor wheel cover, which poses a risk of making abnormal noise.

[0003] In view of this, Chinese utility model patent CN223039787U discloses a motor wheel cover structure for a window regulator, including a wheel cover body with a cable channel for a cable, and openings at both ends of the cable channel for mounting guide tubes. A buffer device is detachably installed in the openings. However, the buffer device has a relatively complex structure, many parts, and high cost; in addition, the guide tube is only inserted into the opening of the wheel cover body at one end, making it prone to falling off and resulting in poor stability.

[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a motor wheel cover structure for a glass lifter, which addresses the shortcomings of the prior art and solves the problems of complex structure, high cost, easy detachment of guide tube, and poor stability of the buffer device in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor wheel cover structure for a glass lifter, comprising a wheel cover body, with openings at both ends of the wheel cover body, an opening groove facing outwards, a first clearance hole at the bottom of the opening groove for the cable to pass through, a guide tube fitted inside the opening groove, a butterfly washer installed at the bottom of the opening groove that can abut against the guide tube, a butterfly spring integrated into the butterfly washer through an integral molding process, and a second clearance hole at the center of the butterfly washer.

[0007] By adopting the above technical solution, the butterfly gasket and the built-in butterfly spring can provide elastic buffering when the guide tube is impacted, reducing abnormal noise; the one-piece molding process simplifies the structure, reduces the number of parts, and lowers the cost.

[0008] A further provision of the above technical solution is that the butterfly gasket is made of rubber, and the butterfly spring is integrally molded into the butterfly gasket by injection molding.

[0009] Using the above technical solution, the rubber butterfly gasket has good elasticity and sound insulation effect. It is integrally molded with the butterfly spring through injection molding, which makes it firmly connected, improves elastic strength, and ensures the stability of cushioning performance.

[0010] A further provision of the above technical solution is as follows: a groove is provided on the outer circumferential surface of the guide tube near the butterfly washer, and movable holes communicating with the groove are provided on both sides of the opening. A locking strip is connected to the inner wall of the movable hole on the axial side of the opening. The unconnected end of the locking strip can float radially relative to the opening and a locking block is provided on the side facing the groove. The locking block can be locked into the groove to achieve locking.

[0011] By adopting the above technical solution, the guide tube can be axially limited by the snap-fit ​​structure in which the snap-fit ​​block is inserted into the slot, preventing it from falling out of the slot and improving the stability of the guide tube installation.

[0012] A further feature of the above technical solution is that the card slot is configured as a ring structure.

[0013] By adopting the above technical solution, the annular groove allows the guide tube to engage with the block at any angle in the circumference, which facilitates angle adjustment during installation and improves assembly convenience.

[0014] A further feature of the above technical solution is that the end of the card block near the card slot is hemispherical, and the two upper edges of the card slot are rounded.

[0015] By adopting the above technical solution, the hemispherical locking block and the rounded edge can reduce the frictional resistance during locking, making it easier for the locking block to slide into the slot, while reducing wear during locking and extending service life.

[0016] A further provision of the above technical solution is that a sound insulation plate is provided between the butterfly gasket and the bottom of the opening groove, and a third clearance hole is provided in the center of the sound insulation plate for the cable to pass through.

[0017] By adopting the above technical solution, the sound insulation panel can further absorb the noise generated during the buffering process, enhance the overall sound insulation effect of the structure, and the third clearance hole ensures that the cable passes through normally.

[0018] A further provision of the above technical solution is that the sound insulation board is made of polyester fiber.

[0019] Using the above technical solution, polyester fiber has good sound insulation and sound absorption properties, and is lightweight and low in cost, making it suitable as a sound insulation board material.

[0020] The beneficial effects achieved by this utility model are as follows: by setting a butterfly washer with a built-in butterfly spring, the structure is simplified, the number of parts is reduced, and the cost is lowered while ensuring the buffering and quiet effect; the cooperation of the locking strip, locking block and locking groove effectively prevents the guide tube from falling off and improves stability.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-4 As shown, a motor wheel cover structure for a window regulator includes a wheel cover body 1. The wheel cover body 1 has openings 11 at both ends, and each opening 11 has an outwardly facing groove 12. The bottom of the groove 12 has a first clearance hole 121 for the cable to pass through. A guide tube 2 is fitted inside the groove 12. A butterfly-shaped washer 3, capable of abutting against the guide tube 2, is installed at the bottom of the groove 12. The butterfly-shaped washer 3 has a butterfly spring 31 integrally molded inside it, and a second clearance hole 32 is located at the center of the washer 3. The butterfly washer 3 is made of rubber, and the butterfly spring 31 is integrally molded into the butterfly washer 3 via injection molding.

[0028] like Figure 1-4As shown, a groove 21 is provided on the outer circumference of the guide tube 2 near the butterfly washer 3. Movable holes 111 communicating with the opening groove 12 are provided on both sides of the opening 11. A retaining strip 4 is connected to the inner wall of the movable hole 111 on one axial side of the opening 11. The unconnected end of the retaining strip 4 can float radially relative to the opening 11, and a retaining block 41 is provided on the side facing the groove 21. The retaining block 41 can be engaged into the groove 21 to achieve a locking connection. The groove 21 is a ring structure. The end of the retaining block 41 near the groove 21 is hemispherical, and the two upper edges of the groove 21 are rounded.

[0029] like Figure 2-4 As shown, a sound insulation plate 5 is also provided between the butterfly gasket 3 and the bottom of the opening groove 12, and a third clearance hole 51 for the cable to pass through is provided in the center of the sound insulation plate 5.
