Abstract
Description
Technical Field
[0001] This utility model relates to the field of car door glass guide rail technology, specifically, to a shock-absorbing car door glass guide rail. Background Technology
[0002] Traditional car door glass guide rails mostly employ a rigid structure, using metal or hard plastic components to guide and limit the glass. While simple in structure, they lack an effective shock absorption and cushioning mechanism. During vehicle operation, especially on bumpy roads or when vibrations occur, hard collisions and friction easily occur between the glass and the guide rail. This not only transmits abnormal noises and vibrations into the vehicle, affecting ride comfort, but also easily causes scratches or even cracks on the glass surface with long-term use. Furthermore, existing guide rails have limited adjustability, are inconvenient to install and maintain, and are difficult to adapt to the needs of different vehicle models or variations in glass thickness. Therefore, those skilled in the art provide a shock-absorbing car door glass guide rail to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this utility model is to provide a shock-absorbing door glass guide rail to solve the problems of existing door glass guide rails.
[0004] This utility model provides the following technical solution: a shock-absorbing car door glass guide rail, comprising symmetrically distributed clamping plates, with rollers symmetrically arranged between the two sets of clamping plates, the rollers being made of soft rubber, and a bolt being sleeved through the middle of the rollers, and the clamping plates being sleeved with the bolts, with mounting plates provided on the inner sides of both sets of clamping plates, and a contact plate being provided on the inner side of the mounting plate that contacts the car door glass, the side of the contact plate that contacts the car door glass being made of soft rubber, and the mounting plate and the contact plate being spaced apart.
[0005] As a preferred embodiment of the above technical solution, a second nut is threadedly connected to the middle of the clamping plate, and a connecting shaft is fixedly installed at one end of the second nut located on the inner side of the clamping plate. First nuts are symmetrically arranged at the upper and lower ends of the second nut, and the first nuts extend through the clamping plate to the interior of the mounting plate. Both the clamping plate and the mounting plate are threadedly connected to the first nuts.
[0006] As a preferred embodiment of the above technical solution, a pad is provided on the inner side of the mounting plate, and the inner side of the pad is in contact with the side wall of the contact plate. The side wall of the pad is provided with an inwardly extending central groove, and the connecting shaft extends through the mounting plate and the central groove to the inner side of the contact plate.
[0007] As a preferred embodiment of the above technical solution, the contact plate has an inwardly recessed socket groove on the side near the pad, and the contact plate is sleeved with the connecting shaft through the socket groove, the cross-section of the socket groove being T-shaped.
[0008] As a preferred embodiment of the above technical solution, the contact plate is symmetrically equipped with arc-shaped spring pieces on the upper and lower sides through the sleeve groove, and the arc surface of the spring pieces contacts the outer side of the connecting shaft.
[0009] As a preferred embodiment of the above technical solution, the outer side of the clamping plate is provided with an inwardly recessed storage groove. The size of the storage groove is larger than the size of the second nut. The storage groove facilitates the storage of the second nut and increases the adjustment stroke of the second nut.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention effectively reduces the impact and noise generated during window lifting and vehicle vibration by using soft rubber rollers and contact plates, combined with the buffering action of arc-shaped spring sheets and connecting shafts. This significantly improves the smoothness of window operation and ride comfort. At the same time, the adjustable second nut and storage groove structure facilitates installation and maintenance, adapts to different glass thicknesses, enhances the practicality and adaptability of the guide rail, and extends the service life of both the glass and the guide rail.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0014] Please see Figure 1 - Figure 5As shown, this utility model provides a technical solution: a shock-absorbing car door glass guide rail, including symmetrically distributed clamping plates 1, with rollers 12 symmetrically arranged between the two sets of clamping plates 1. The rollers 12 are made of soft rubber, and a bolt 2 is sleeved through the middle of the roller 12. The clamping plates 1 are sleeved with the bolts 2. The inner side of each set of clamping plates 1 is provided with a mounting plate 3, and the inner side of the mounting plate 3 is provided with a contact plate 9 that contacts the car door glass. The side of the contact plate 9 that contacts the car door glass is made of soft rubber. The mounting plate 3 and the contact plate 9 are spaced apart.
[0015] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, a second nut 5 is threadedly connected to the middle of the clamping plate 1. A connecting shaft 6 is fixedly installed at one end of the second nut 5 located inside the clamping plate 1. A first nut 4 is symmetrically arranged at the upper and lower ends of the second nut 5. The first nut 4 extends through the clamping plate 1 into the interior of the mounting plate 3. Both the clamping plate 1 and the mounting plate 3 are threadedly connected to the first nut 4.
[0016] Furthermore, a pad 7 is provided on the inner side of the mounting plate 3, and the inner side of the pad 7 is in contact with the side wall of the contact plate 9. The side wall of the pad 7 is provided with an inwardly extending central groove 8, and the connecting shaft 6 passes through the mounting plate 3 and the central groove 8 and extends to the inner side of the contact plate 9.
[0017] As one implementation method in this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 As shown, the contact plate 9 has an inwardly recessed socket groove 10 on the side near the pad 7. The contact plate 9 is sleeved with the connecting shaft 6 through the socket groove 10. The cross-section of the socket groove 10 is T-shaped.
[0018] Furthermore, the contact plate 9 is symmetrically equipped with arc-shaped spring pieces 11 on the upper and lower sides through the sleeve groove 10, and the arc surface of the spring piece 11 is in contact with the outer side of the connecting shaft 6.
[0019] Furthermore, the outer side of the clamping plate 1 is provided with an inwardly recessed storage groove 13. The size of the storage groove 13 is larger than the size of the second nut 5. The storage groove 13 facilitates the storage of the second nut 5 and can increase the adjustment stroke of the second nut 5.
[0020] Working principle: When in use, the device is first installed in the reserved position. When the car window glass is raised or lowered, the side of the glass contacts the roller 12, and the roller 12 limits and guides the car window glass. During installation, the second nut 5 can be rotated to push the pad 7 and the contact plate 9 to move, so that the two sets of contact plates 9 come closer to each other and fit against both sides of the car door glass. This limits the movement of the car door glass, and the soft rubber material on the inside of the contact plate 9 prevents damage to the car door glass. At the same time, when the vehicle is bumped and the car door glass shakes, the shaking glass will cause the contact plate 9 to shake back and forth under the action of friction, thereby squeezing the symmetrically arranged springs 11 to buffer and dampen the car door glass, thus fully protecting the car door glass.
[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
