Description

Technical Field

[0001] The present application relates to the field of automobile parts, and in particular to an automobile seat guide rail assembly with a self-lubricating function. Background Art

[0002] Currently, most automotive seat rails utilize technology that lacks self-lubricating properties. Traditional seat rails rely on regular application of lubricant to reduce friction, ensure smooth movement, and prevent rust. While this lubrication method works to a certain extent, it still has many drawbacks. First, traditional lubrication requires regular maintenance, increasing the complexity and cost of vehicle maintenance. Furthermore, the effectiveness of lubricant application can gradually decrease over time, especially when the rails are frequently used or exposed to high temperatures, high humidity, and other environmental influences. The lubricant's effectiveness can become unstable, increasing rail friction and even accelerating component wear and aging. More seriously, if lubricant is not replenished on time or applied unevenly, the rails may become stuck or rust, affecting proper seat adjustment and operation, and in severe cases, posing a safety hazard.

[0003] The root cause of this shortcoming lies in the dependency and instability of traditional lubrication methods. While regular lubrication effectively reduces friction, it relies on manual maintenance and operation. Lack of timely maintenance or improper operation can compromise lubrication effectiveness. Furthermore, as the lubricant depletes or becomes contaminated, the guide rail surface loses its protective properties, leading to direct contact between metal parts and friction, further exacerbating wear. Furthermore, the impact of the external environment on lubricants cannot be ignored. High temperatures, cold weather, and changes in humidity can all reduce lubrication effectiveness.

[0004] Therefore, it is of great significance to develop automobile seat rail technology with self-lubricating function. Utility Model Content

[0005] The purpose of this application is to overcome at least one of the shortcomings of the prior art and to provide a car seat rail assembly with a self-lubricating function. The seat rail assembly can continuously release lubricating oil and achieve self-lubrication by setting an oil storage tank in the rail slider or using self-lubricating materials, thereby reducing dependence on external maintenance, extending the service life of the rail, and improving the comfort and safety of the seat.

[0006] To achieve the above-mentioned purpose, the present application discloses a car seat guide rail assembly with a self-lubricating function, wherein the seat guide rail assembly includes a guide rail, a sliding member installed in the guide rail and capable of sliding along the guide rail, wherein the guide rail has two inner guide surfaces that are perpendicular and equal to each other, and the sliding member has an outer guide surface corresponding to the inner guide surface, and the inner guide surface and the outer guide surface are tightly fitted against each other; a plurality of oil storage microgrooves are provided on the inner guide surface along the guide rail direction; the sliding member is provided with at least one oil storage cavity with lubricating grease, the oil storage cavity is opposite to the outer guide surface, and a channel is opened between the outer guide surface and the oil storage cavity, and an oil guide cotton member is provided in the channel, and the front end of the oil guide cotton member is exposed from the outer guide surface and contacts with the inner guide surface.

[0007] In some embodiments, the cross section of the sliding member is in the shape of an X.

[0008] In some embodiments, a connection hole for installing a car seat is provided at a position of the sliding member that avoids the oil storage cavity.

[0009] Compared with the prior art, this application has at least one of the following beneficial effects:

[0010] 1. Reduced Maintenance Requirements: By incorporating an oil reservoir or utilizing self-lubricating materials within the guide rail sliders, the seat rails are self-lubricating, reducing reliance on external manual maintenance. This design ensures a continuous and automatic lubrication supply, avoiding increased friction and component damage caused by untimely or uneven manual application, thereby improving overall maintenance convenience and reliability.

[0011] 2. Extend the life of the guide rail: The self-lubricating function can maintain proper lubrication between the guide rail and the sliding parts, effectively reducing friction, and reducing component wear and aging. In this way, the service life of the seat rail can be greatly extended, avoiding frequent replacement and high maintenance costs.

[0012] 3. Improved seat comfort and safety: The self-lubricating system provides a steady supply of lubricant, ensuring smooth guide rail movement. This results in smoother seat adjustment and an improved user experience. Furthermore, reduced friction reduces the likelihood of guide rail components becoming stuck or rusting, ensuring proper seat adjustment and safety.

[0013] 4. Adaptability to Complex Environmental Conditions: Compared to traditional oiling methods, self-lubricating seat rails maintain stable lubrication across a wider range of temperatures and humidity. Even in extreme environments such as high temperature, high humidity, or cold, the system continuously releases lubricant, ensuring smooth operation and minimizing the negative impact of the external environment on lubrication.

[0014] The above-listed beneficial effects are not exhaustive and other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description sections of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Refer to the attached Figure 1-3 This embodiment discloses a self-lubricating automotive seat rail assembly, designed to address existing issues such as the reliance on manual lubrication and unstable lubrication. This seat rail assembly utilizes an innovative structural design to achieve automatic lubrication between the rail and the sliding member, extending the assembly's service life and improving seat adjustment comfort and safety. The following describes in detail the various components of this embodiment and their connections and mating relationships.

[0024] First, the guide rail 1 is the main load-bearing part of the seat guide rail assembly and is usually made of steel, aluminum alloy or corrosion-resistant alloy materials to ensure that it has sufficient mechanical strength, durability and corrosion resistance. Two vertical and mutually parallel inner guide surfaces 3 are provided inside the guide rail 1. These two inner guide surfaces 3 are parallel to each other and precisely matched with the outer guide surface 4 of the slider 2 to ensure that the slider 2 can slide smoothly inside the guide rail 1. The design of the inner guide surface 3 not only meets the requirements of load bearing and guidance, but also forms a basic self-lubricating structure by arranging several oil storage micro grooves 5 along the direction of the guide rail 1. The oil storage micro grooves 5 are evenly distributed on the inner guide surface 3 of the guide rail 1 and can continuously release lubricating oil during the movement of the slider 2, thereby effectively reducing friction and extending the service life of the guide rail 1 and the slider 2.

[0025] The sliding member 2 is a component used in conjunction with the guide rail 1. It is installed inside the guide rail 1 and slides along it. The cross-section of the sliding member 2 is a structure similar to the Chinese character "J". This design enables the sliding member 2 to provide more stable support inside the guide rail 1 and has better sliding performance. The outer guide surface 4 of the sliding member 2 is tightly matched with the inner guide surface 3 of the guide rail 1, ensuring low-friction sliding between the two. Inside the sliding member 2, there is provided at least one oil storage chamber 6, which is opposite to the outer guide surface 4 and is connected to the inner guide surface 3 through a channel. An oil guide cotton piece 7 is provided in the channel, which absorbs the lubricating grease in the oil storage chamber 6 through capillary action and transports it to the outer guide surface 4 of the sliding member 2 to ensure continuous lubrication between the sliding member 2 and the guide rail 1. The design of the oil storage chamber 6 and the use of the oil guide cotton piece 7 ensure that the lubricating oil can be evenly distributed on the contact surface between the guide rail 1 and the sliding member 2, thereby reducing friction, reducing wear and improving the smoothness of seat adjustment.

[0026] In order to facilitate the installation of the sliding member 2 and the seat structure, connection holes are opened in certain parts of the sliding member 2. These connection holes are used to fix the sliding member 2 to the frame structure of the car seat to ensure that the seat adjustment mechanism can operate stably.

[0027] The working principle of this embodiment is as follows: when the seat guide rail assembly is put into use, the slider 2 slides along the guide rail 1. As the slider 2 moves, the lubricating oil in the oil storage microgroove 5 is guided to the outer guide surface 4 of the slider 2, and the lubricating oil is transported to the oil storage chamber 6 through the channel. The oil guide cotton piece 7 plays the role of grease diversion between the oil storage chamber 6 and the outer guide surface 4. The lubricating grease is absorbed by the oil guide cotton piece 7 and evenly transported to the outer guide surface 4 of the slider 2 through capillary action, thereby maintaining continuous lubrication between the slider 2 and the guide rail 1. In this way, the friction between the slider 2 and the guide rail 1 is always maintained at a low level, ensuring a smooth and smooth adjustment process of the seat, while avoiding the uneven application of lubricating oil and the need for manual maintenance that are common in traditional oiling methods.

[0028] Compared to traditional automotive seat rail technology, the self-lubricating function of this embodiment significantly improves seat rail performance. First, it reduces the need for manual lubrication, avoids the problem of lubrication effectiveness degrading over time, and significantly reduces maintenance costs and complexity. Second, the continuous lubrication between the rail 1 and the slider 2 reduces friction and wear, extending the service life of the entire assembly and reducing the frequency of replacement and repair. Finally, seat adjustment is smoother, providing greater comfort. The continuous supply of lubricant effectively prevents rust or sticking on the rail 1 and slider 2, ensuring safety during use.

[0029] Furthermore, the self-lubricating design of this embodiment is adaptable to various working environments. While conventional lubricants may lose their lubricating effectiveness due to environmental changes, such as high or low temperatures or changes in humidity, the self-lubricating design of this embodiment, through the interaction between the oil-reservoir microgrooves 5 and the oil-reservoir cavity 6, can stably and continuously provide lubricating oil, ensuring the normal operation of the guide rail 1 and the sliding member 2 under various environmental conditions.

[0030] In summary, this embodiment provides a car seat rail assembly with a self-lubricating function, which adopts an innovative lubrication design, significantly improves the performance of the seat rail, reduces maintenance costs, extends the service life of the assembly, and improves the comfort and safety of seat adjustment. It has good application prospects and market value.
