Description

Technical Field

[0001] This utility model relates to the field of automotive window lifting technology, specifically to a lubrication structure for automotive window lifting guide rails. Background Technology

[0002] The window lift system is generally driven by a lifter located below the window glass, which moves the window glass up and down along the guide rails on both sides of the car frame.

[0003] Traditionally applied grease, when exposed to air, melts and flows in the high temperatures of summer and hardens in the low temperatures of winter, and oxidizes over time. This results in a lack of long-lasting lubrication, requiring frequent inspections and touch-ups by users or maintenance personnel, and failing to achieve long-term maintenance-free operation. To address these issues, we have proposed a lubrication structure for automotive window lift rails. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lubrication structure for automotive window lifting guide rails, solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a lubrication structure for an automotive window lifting guide rail, including a single-sided guide rail, a steel wire rope, and a glass bracket slidably connected to the single-sided guide rail, and also includes a limiting mechanism and an oil storage base. The limiting mechanism is fixedly installed on the single-sided guide rail, and the oil storage base is composed of an adsorption layer and a wear-resistant layer, and the oil storage base is disposed inside the limiting mechanism. The adsorption layer can adsorb and store lubricating grease, the wear-resistant layer covers the outer surface of the adsorption layer, and the wear-resistant layer has a number of micropores. The oil storage substrate is fixedly positioned by the limiting mechanism so that the wear-resistant layer comes into contact with the wire rope.

[0006] Preferably, the limiting mechanism includes a housing, which is fixed on the single-sided guide rail, and the oil storage base is inserted into the housing.

[0007] Preferably, the inner wall of the box is fixedly provided with a baffle to restrict the insertion position of the oil storage substrate.

[0008] Preferably, the limiting mechanism further includes a U-shaped stop bar and a key, wherein the U-shaped stop bar and the key bar are integrally formed, and the key bar can be inserted into the opening surface of the box body so that the U-shaped stop bar restricts the oil storage substrate inside the box body.

[0009] Preferably, the limiting mechanism further includes a connecting plate, which is fixedly connected to the box body by bolts. A plug rod is provided on the side of the connecting plate, and a plug hole matching the plug rod is provided on the plug rod.

[0010] Preferably, the adsorption layer is made of porous rubber, the wear-resistant layer is made of polyoxymethylene, and the micropores are uniformly distributed on the wear-resistant layer.

[0011] Preferably, a pulley is provided on the side of the single-sided guide rail, the steel wire rope slides in contact with the pulley, and the steel wire rope is also fixedly connected to the glass bracket.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The lubrication structure of this automotive window lift guide rail uses an adsorption layer made of porous rubber as an "oil reservoir" to pre-adsorb and store a large amount of lubricating grease. This avoids the short-term failure problem caused by grease loss and drying in traditional methods. The lubricating grease slowly seeps out through the micropores on the polyoxymethylene wear-resistant layer, rather than being supplied in large quantities at once. This mechanism ensures that there is always a thin oil film on the friction surface of the wire rope, providing a continuous and stable lubrication effect and avoiding dry friction and abnormal noise caused by lubrication interruption.

[0015] 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.

[0016] Please see Figure 1-4A lubrication structure for a car window lifting guide rail includes a single-sided guide rail 1, a steel wire rope 3, and a glass bracket 2 slidably connected to the single-sided guide rail 1. A pulley 4 is provided on the side of the single-sided guide rail 1, the steel wire rope 3 slides in contact with the pulley 4, and the steel wire rope 3 is also fixedly connected to the glass bracket 2.

[0017] It also includes a limiting mechanism 5 and an oil storage substrate 51. The limiting mechanism 5 is fixedly installed on the single-sided guide rail 1. The oil storage substrate 51 is composed of an adsorption layer 511 and a wear-resistant layer 512 and is located inside the limiting mechanism 5. The adsorption layer 511 can adsorb and store lubricating grease. The wear-resistant layer 512 covers the outer surface of the adsorption layer 511 and has several micropores 513. The adsorption layer 511 is made of porous rubber. Its porous structure can discharge grease when squeezed and stop supplying when the pressure is removed, realizing an intelligent lubrication mechanism of "distribution on demand". This greatly improves the utilization rate of lubricating oil and avoids waste. The wear-resistant layer 512 is made of polyoxymethylene. Polyoxymethylene has an extremely low coefficient of friction and excellent wear resistance, which means that it wears very little when rubbing against the wire rope 3 and has a long service life. At the same time, it can ensure that the wire rope 3 slides extremely smoothly and effectively reduces operating noise. The micropores 513 are evenly distributed on the wear-resistant layer 512.

[0018] The oil reservoir 51 is fixedly positioned by a limiting mechanism 5 to ensure that the wear-resistant layer 512 contacts the wire rope 3. The limiting mechanism 5 includes a housing 52, which is fixed on a single-sided guide rail 1. The oil reservoir 51 is inserted into the housing 52. A baffle 57 is fixedly provided on the inner wall of the housing 52 to limit the insertion position of the oil reservoir 51. The baffle 57 is crucial as it provides a hard stop when the oil reservoir 51 is inserted, ensuring its insertion position and allowing the wear-resistant layer 512 to be in the optimal position for contact with the wire rope 3. The limiting mechanism 5 also includes a U-shaped stop bar 53 and a key 56, which are integrally formed. The key 56 can be inserted into the opening of the housing 52 so that the U-shaped stop bar 53 restricts the oil storage base 51 inside the housing 52. The U-shaped stop bar 53 can cross and press the oil storage base 51, effectively preventing it from loosening or falling out of the housing 52 under the action of vehicle vibration, impact or friction of the wire rope 3, ensuring the reliability of the operation. The limiting mechanism 5 also includes a connecting plate 54, which is fixedly connected to the housing 52 by bolts. The side of the connecting plate 54 is provided with a plug bar 55. The key 56 is provided with a plug hole that matches the plug bar 55 to prevent the key 56 from accidentally coming out of the housing 52, thereby locking the entire mechanism.

[0019] Working principle: The oil storage substrate 51 consists of an adsorption layer 511 and a wear-resistant layer 512. The adsorption layer 511 acts like a "sponge," capable of adsorbing and storing a large amount of lubricating grease. When the steel wire rope 3 slides along the pulley 4, and the glass bracket 2, which is fixedly connected to the steel wire rope 3, slides inside the single-sided guide rail 1, the steel wire rope 3 will rub against the wear-resistant layer 512 on the surface of the oil storage substrate 51 and squeeze the adsorption layer 511 below it. The squeezing action causes the lubricating grease in the oil storage substrate 51 to slowly and continuously penetrate to the friction surface through the micropores 513 on the wear-resistant layer 512, forming an extremely thin oil film to achieve lubrication. When the friction stops, the squeezing action disappears, and the lubricating oil seeps out. The oil storage base 51 is first inserted into the box 52, and a baffle 57 is fixed to the inner wall of the box 52 to limit the insertion position of the oil storage base 51. Then, using the key 56, the U-shaped stop bar 53 integrally formed with the key 56 is inserted into the opening of the box 52. Then, the plug bar 55 on the side of the connecting plate 54 is inserted into the plug hole of the key 56, and the connecting plate 54 is locked with bolts. At this time, the U-shaped stop bar 53 can be locked in the opening of the box 52. The position of the oil storage base 51 is limited inside the box 52 by the U-shaped stop bar 53, and the box 52 is also fixed to the single-sided guide rail 1 with bolts.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
