The drawings only show the components related to this disclosure and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0018] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0019] As shown in the figure, an aluminum alloy sliding window of this application includes a window frame 1, a sliding window sash 2, a ball bearing slide rail assembly 3, a sealing strip 4, and a clamping component 5. These components, through reasonable design and fit, form a stable sliding sealing structure, aiming to optimize the performance of the sliding window and extend its service life.

[0020] The window frame 1 is the basic supporting structure of the sliding window. It is typically made of aluminum alloy profiles and has a rectangular frame design to fit the wall opening. The window frame 1 has two parallel guide grooves to accommodate the sliding window sash 2 and provide a path for its movement. In addition, the window frame 1 is equipped with bolt holes and other mounting points to securely fix the entire window frame 1 to the building wall or doorway. The design of the window frame 1 must also ensure good strength and corrosion resistance; for example, surface anodizing treatment can enhance its anti-aging properties.

[0021] The sliding window sash 2 is located inside the window frame 1 and slides open and closes along the guide rails within the window frame 1. This window sash is primarily constructed of an aluminum alloy frame and can be fitted with single or double glazing as the main body, serving to isolate the interior and exterior environments. To ensure smooth operation, specific locking mechanisms are installed at the bottom and on both sides, combined with the ball bearing slide rail assembly 3. Furthermore, the perimeter of the sliding window sash 2 is designed to be slightly smaller than the inner frame of the window frame 1, facilitating sliding in and out while avoiding excessive gaps.

[0022] The ball bearing slide rail assembly 3 is positioned between the window frame 1 and the sliding window sash 2, playing a crucial sliding support role. Specifically, the ball bearing slide rail comprises a rigid metal track and multiple sets of small rolling bearing balls distributed along the track. The outer surface of the bearing balls undergoes a special micro-arc oxidation process to form a wear-resistant coating. This technology not only reduces the coefficient of friction between materials but also improves its lifespan, resisting wear caused by prolonged operation. In addition, a layer of 301 rubber buffer pads is added inside the slide rail to absorb vibrations and impact noise that may be generated during operation, greatly improving the noise reduction effect. For example, nylon or polyurethane can be used as an elastic substrate combined with high-performance ceramic balls to further reduce noise sources.

[0023] The sealing strip 4 is embedded in the edge of the sliding window sash 2. When the sliding window is closed, it fits tightly against the window frame 1, forming a sturdy barrier to prevent harsh external conditions such as dust or noise from entering the indoor environment. This sealing strip 4 is generally made of flexible EPDM foam rubber because it has excellent extensibility and compression resilience. Even if deformed by external pressure, it can instantly return to its original shape after the pressure is removed, maintaining its sealing performance intact. Furthermore, the cross-sectional shape of the sealing strip 4 can be selected according to actual needs; a common style is a V-shaped groove structure, which can more securely clamp the gap between the window sash frame and prevent loosening.

[0024] The clamping component 5 is securely assembled with the window frame 1. The initial gap between the ball bearing slide rail system is adjusted by turning the adjusting screw to change the force. This operation is crucial because it determines whether the overall structure remains in optimal condition after assembly. If the originally set working gap is found to have changed due to the thermal expansion and contraction of the aluminum alloy caused by seasonal climate changes, it can be restored to its original state by simply fine-tuning the clamping component 5 without having to disassemble and reassemble the entire device.

[0025] To address the technical challenge of optimizing the ball bearing slide rail design for aluminum alloy sliding windows to reduce wear and improve noise reduction over long-term use, the aforementioned design solution addresses this issue from three aspects: First, small-diameter ceramic balls treated with micro-arc oxidation are used, significantly reducing frictional resistance between the rolling elements and the guide rail interface and enhancing oxidation resistance to slow down component wear cycles. Second, a layer of flexible, high-quality independent rubber buffer pad 301 is creatively added as an auxiliary device to eliminate noise interference caused by hard impacts, making the entire system operate more quietly and harmoniously. Third, precise and adjustable clamping elements allow users to flexibly adjust the precise distances between various components of the system at any time according to actual conditions to maintain ideal operational balance. These combined effects significantly improve the reliability of aluminum doors and windows in daily use and enhance customer satisfaction.

[0026] In one embodiment, the ball bearing slide rail assembly 3 of an aluminum alloy sliding window of this application adopts a closed structural design. Specifically, the metal slide rail 6 is fully enclosed, and its internal space is used to accommodate and encapsulate the ball bearings, allowing the ball bearings to roll within a defined area, preventing external dust from entering the track interior, thereby reducing functional degradation caused by wear. Through this design, the assembly can maintain high-precision sliding performance during long-term use and effectively isolate the impact of external contaminants on the internal mechanical structure.

[0027] The aforementioned features can be achieved through specific technical means. For example, during actual assembly, the enclosed metal slide rail 6 is fixedly installed in a predetermined area between the window frame 1 or the sliding window sash 2, while ensuring that the slide rail and the bottom contact part of the window sash remain parallel and aligned, thereby providing stable support and guiding function. To achieve complete encapsulation of the ball bearings, a metal material with seamless joint characteristics can be used to manufacture the slide rail housing, and precision machining methods can be used to ensure the housing's sealing and the integrity of the overall structure.

[0028] In one embodiment, the ball bearing slide rail assembly 3 of an aluminum alloy sliding window of this application further improves sliding efficiency by coating the ball bearing surface with a nano-lubricating coating. This coating has a low coefficient of friction, significantly reducing wear on the contact surface between the ball bearing and the slide rail during use, and ensuring smooth and stable rolling. The nano-lubricating coating is made of high-temperature resistant and oxidation-resistant materials, suitable for complex and variable climatic conditions. The ball bearing slide rail assembly 3 is installed between the window frame 1 and the sliding window sash 2, with a reasonable positioning design that neither affects the opening and closing function of the window sash nor hinders its effective support. This assembly adopts a split design, in which the ball bearing is individually embedded in the track groove and precisely assembled with the sliding mechanism.

[0029] For example, to achieve the technical characteristics of the nano-lubricating coating on the ball bearing surface, the ball bearing surface can be pretreated to improve adhesion, and then the coating material can be applied using magnetron sputtering or dip coating. The coating thickness is precisely controlled to ensure that the original structural dimensions and function are not altered. During the assembly of the entire ball bearing slide assembly 3, attention should also be paid to maintaining the coaxiality and parallelism between the parts to meet the stability requirements for long-term use.

[0030] In one embodiment, the ball bearing slide rail assembly 3 of an aluminum alloy sliding window of this application is equipped with rubber buffer pads 301 on both sides. These rubber buffer pads 301 are not simply placed on both sides of the ball bearing slide rail assembly 3, but are fixedly connected via grooves 8 to ensure that they do not shift or detach during long-term use. The presence of the rubber buffer pads 301 effectively absorbs additional vibrations or impacts caused by collisions or other reasons during the movement of the sliding window sash 2. Simultaneously, the design of the grooves 8 firmly restricts the buffer pads to their intended installation positions, further enhancing structural stability. Specifically, the rubber buffer pads 301 are pre-processed to conform to the geometric shape of the ball bearing slide rail assembly 3 and are connected via a mechanical fastening method using the grooves 8.

[0031] For example, in practical implementation, appropriate positioning grooves can be designed on both sides of the ball bearing slide assembly 3 to allow the rubber buffer pad 301 to be precisely inserted and engaged. At the same time, the locking force can be strengthened by adding protrusions or barbs to the inner edge of the groove 8, thereby preventing the buffer pad from sliding or coming off under external force or fatigue.

[0032] To achieve the above features from a technical perspective, molded scraper blades combined with a precisely machined frame can be used to ensure overall accuracy after assembly. To meet practical application requirements, the thickness and hardness parameters of the scraper blades can be adjusted to achieve optimal adaptation to different types of slide rails.

[0033] In one embodiment, the sealing strip 4 of an aluminum alloy sliding window of this application is made of flexible rubber material and designed with a micro-barb structure to enhance adhesion to the edge of the sliding window sash 2. Specifically, the sealing strip 4 is set on the edge of the sliding window sash 2, and its installation position needs to form a good fit with the window frame 1 to ensure the airtightness and sound insulation performance of the sliding window when closed. In addition, the choice of flexible rubber material ensures the applicability of the sealing strip 4 under various temperature and humidity conditions, and can adapt to the deformation requirements caused by frequent opening and closing of the sliding window during use.

[0034] Further describing the structural features of the sealing strip 4, the micro-barbs on its outer surface are manufactured using a special mold forming process. These barbs are arranged along the length of the sealing strip 4 to improve the stability of the sealing strip 4 when assembled on the sliding window sash 2 and to resist the risk of accidental detachment. For example, in practical applications, the sealing strip 4 can be embedded in a groove of appropriate depth pre-drilled at the edge of the sliding window sash 2, and its position can be fixed by the interlocking force between the micro-barb structure and the inner wall of the groove.

[0035] Specifically, from a technical implementation perspective, these miniature barbs can be manufactured using secondary injection molding or direct molding techniques, thereby precisely controlling the height, spacing, and shape of the barbs to ultimately meet the stability and reliability requirements of the overall sliding window structure. Furthermore, the two ends of the sealing strip 4 need to be designed with appropriate mating structures to ensure no noticeable gaps.

[0036] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
