[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] One preferred embodiment of this application, such as Figures 1 to 6As shown, a low-vibration-transmission car sunroof guide rail includes a guide rail body 1. A guide groove 11 is provided on the side of the guide rail body 1, allowing the sunroof to slide smoothly along the guide groove 11. A storage cavity 2 is provided on the side of the guide rail body 1, and lubricating fluid is injected into the storage cavity 2. An inclined part 12 is provided between the bottom of the storage cavity 2 and the guide groove 11. A through hole 21 is provided at the bottom of the storage cavity 2, allowing the lubricating fluid to drip onto the inclined part 12. The inclined part 12 then allows the lubricating fluid to flow slowly and continuously into the guide groove 11 under the action of gravity, effectively preventing the problem of excessive lubricating fluid concentration leading to localized over-lubrication and dryness in other areas. This facilitates better movement of the sunroof within the guide groove 11, reducing frictional resistance and allowing the sunroof to slide smoothly with reduced vibration and noise, improving ride comfort. An intermittent block 13, which cooperates with the sunroof system, is rotatably provided at the bottom of the storage cavity 2. An intermittent block 13 has an opening on its side. There are multiple openings that mate with the through-hole 21. When the sunroof is opened and closed, the sunroof system drives the intermittent block 13 to rotate, so that the intermittent block 13 gradually aligns with or offsets the blocked through-hole 21, controlling the periodic dripping of lubricating fluid, reducing unnecessary waste, and improving the practicality and feasibility of the device. When the through-hole 21 corresponds to the opening on the intermittent block 13, the lubricating fluid can drip more quickly onto the inclined part 12 and flow evenly into the guide groove 11 along the inclined surface of the inclined part 12. Thus, the lubricating fluid can better lubricate the sunroof as it moves within the guide groove 11, allowing the guide groove 11 in the guide rail body 1 to better lubricate the sunroof as it moves. When the intermittent block 13 rotates to the point where the opening and through-hole 21 are misaligned, the flow of lubricating fluid is blocked, effectively preventing excessive leakage of lubricating fluid and causing unnecessary waste. This makes the sunroof move more smoothly and stably, reducing vibration and abnormal noise during movement and extending the service life of the sunroof.

[0026] In this embodiment, as Figure 1 As shown, it can be understood that in order to better lubricate the guide rail body 1, make the lubrication effect more reasonable, and facilitate the better movement of the sunroof, two sets of storage chambers 2 are provided. The two sets of storage chambers 2 are located on the sides of the two guide rail bodies 1 respectively. The two intermittent blocks 13 rotate synchronously to control the periodic release of lubricating fluid in the storage chambers 2 in the two guide rail bodies 1, thereby uniformly lubricating the guide groove 11, avoiding over-lubrication or dryness on one side, further improving the smoothness and sealing of the sunroof sliding, effectively reducing operating noise and mechanical wear, and extending the service life of the guide rail body 1.

[0027] In this embodiment, as Figure 2 and Figure 5As shown, it can be understood that the guide rail body 1 is generally arc-shaped to fit the arc-shaped structure of the sunroof area, so that the guide rail body 1 fits the body more closely, thereby effectively improving the installation accuracy and structural stability, reducing problems such as water leakage caused by assembly deviation, and the storage cavity 2 is set in ways including but not limited to the following three ways.

[0028] Setting method 1: As shown in the example Figure 3 and Figure 4 As shown, the storage cavity 2 is located at the left end of the side of the guide rail body 1, and the lower end of the storage cavity 2 is inclined at the middle of the guide rail body 1, so that the lubricant can flow out completely from the storage cavity 2 under the action of gravity, reducing the residue and waste of lubricant. After the lubricant flows out from the storage cavity 2, it is naturally guided to the guide groove 11 along the inclined part 12. At this time, the lubricant flows at the highest point of the arc of the guide rail body 1. At this time, the lubricant can slide into the guide groove 11 from the highest point to both sides of the guide groove 11, which makes it easier to better spread the lubricant evenly from the center to both sides in the guide groove 11, reducing frictional resistance, and making the sunroof run more smoothly in the guide groove 11, improving the practicality, safety and comfort of the device.

[0029] Setting method two: (e.g.) Figure 3 and Figure 5 As shown, the storage cavity 2 is located at the right end of the side of the guide rail body 1, and the lower end of the storage cavity 2 is inclined at the middle of the guide rail body 1, so that the lubricant can flow out completely from the storage cavity 2 under the action of gravity, reducing the residue and waste of lubricant. After the lubricant flows out from the storage cavity 2, it is naturally guided to the guide groove 11 along the inclined part 12. At this time, the lubricant flows at the highest point of the arc of the guide rail body 1. At this time, the lubricant can slide into the guide groove 11 from the highest point to both sides of the guide groove 11, which makes it easier to better spread the lubricant evenly from the center to both sides in the guide groove 11, reducing frictional resistance, and making the sunroof run more smoothly in the guide groove 11, improving the practicality, safety and comfort of the device.

[0030] Setting method three: (e.g.) Figure 4 and Figure 5 As shown, the storage cavities 2 are respectively located at the left and right ends of the side of the guide rail body 1.

[0031] It is understood that all three of the above-mentioned configuration methods satisfy this application, and those skilled in the art can choose according to the actual situation.

[0032] In this embodiment, as Figure 3 , Figure 4 and Figure 6As shown, it should be understood that a helical gear 131 is provided on the side of the intermittent block 13, and the helical gear 131 meshes with the moving structure of the sunroof system. When the sunroof opens and closes, the moving structure of the sunroof system meshes with the helical gear 131 on the intermittent block 13, causing the helical gear 131 to rotate. This rotation causes the intermittent block 13 to rotate, gradually aligning it with the blocked state of the through hole 21 and then shifting it away. This allows the lubricating fluid in the storage cavity 2 to drip periodically through the connected opening, reducing unnecessary waste and improving the practicality and feasibility of the device. Furthermore, when the through hole 21 corresponds to the opening on the intermittent block 13, the lubricating fluid can drip more quickly. The lubricant drips onto the inclined section 12 and flows evenly into the guide groove 11 along the inclined surface of the inclined section 12. This allows the lubricant to be better contained within the guide groove 11. At this point, the lubricant can naturally slide down to both sides along the highest point of the guide groove 11, thus providing a more even lubrication coverage to the guide groove 11. This effectively reduces the frictional resistance between the guide groove 11 and the sunroof rail, allowing the guide groove 11 within the rail body 1 to better lubricate and move the sunroof. When the intermittent block 13 rotates to the point where the opening and through hole 21 are misaligned, the flow of lubricant is blocked, effectively preventing excessive lubricant seepage and unnecessary waste. This further makes the sunroof move more smoothly and stably, reducing vibration and abnormal noise during movement and extending the service life of the sunroof.

[0033] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, it should be noted that an oil inlet 22 is provided at the top of the storage cavity 2. The oil inlet 22 is located at the middle position away from the guide rail body 1, so that the lubricant can be better injected into the storage cavity 2, which is convenient for later maintenance and replenishment.

[0034] In this embodiment, as Figure 4 and Figure 5 As shown, the oil inlet 22 is equipped with a sealing plug inside, and a connecting groove is provided in the center of the sealing plug. A protective mesh is provided at the top of the connecting groove. The sealing plug can effectively block the oil inlet 22, preventing lubricant leakage or impurities from entering, effectively protecting the cleanliness of the storage chamber 2 and extending the service life of the lubricant. The protective mesh can block dust and particles from entering the connecting groove, ensuring that the lubricant can flow into the guide groove 11 through the through hole 21, which facilitates smooth flow of lubricant. The sealing plug fits tightly with the oil inlet 22, and is easy to install and remove, making it convenient to replenish the lubricant regularly and improving maintenance efficiency.

[0035] In this embodiment, as Figure 1As shown, a drainage groove 3 is provided on the side of the guide rail body 1. The drainage groove 3 extends along the length of the guide rail body 1 and has an arc-shaped cross-section, which can guide the water that seeps into the interior of the guide rail body 1, effectively prevent rainwater from corroding the guide rail body 1, and thus extend the service life of the guide rail body 1.

[0036] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
