Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile sunroof guide rail processing, in particular to a low-resistance automobile sunroof guide rail and a processing device thereof. BACKGROUND

[0002] Currently, automobile sunroof guide rails generally have problems of large movement resistance, noise and the like caused by lubrication failure. Traditional lubrication methods rely on initial smearing or periodic greasing. In long-term use, the lubricating grease is prone to failure due to extrusion loss, high-temperature drying or uneven distribution, resulting in dry friction or boundary friction between the guide rail and the bearing block. This not only significantly increases the sunroof opening and closing resistance, affects the operation smoothness and user experience, but also produces abnormal noise due to increased wear, shortens the service life of the guide rail system. Although some structures attempt to set up oil storage grooves or lubrication channels, it is often difficult to achieve continuous, directional and uniform supply of lubricating grease on multiple sliding surfaces (such as planar sliding rails, roller sliding rails and lateral guide rails), especially to effectively deliver lubricating grease to the surfaces of the two vertical or inclined friction pairs.

[0003] The complex lubrication structure of the guide rail designed to improve the lubrication effect (such as a drainage groove with a specific inclination angle) puts higher requirements on its manufacturing process. The existing processing method usually needs multiple clamping, tool replacement or multiple processes to process the grooves with a space trend, especially grooves with slopes, which not only has low efficiency, but also is difficult to ensure the consistency of the size, angle and position of the groove body. For example, when processing a drainage groove with a continuous slope, the conventional drilling and milling process cannot complete horizontal slotting and vertical forming at once, which is prone to problems such as tool joint marks and size out-of-tolerance, directly affecting the lubrication performance of the guide rail. In view of this, we propose a low-resistance automobile sunroof guide rail and a processing device thereof. SUMMARY

During sliding, the elastic compression extrusion block continuously extrudes the lubricating grease in the extrusion groove, which is uniformly spread on the main sliding surface through the two side flow guide structures, and the other way is to climb to the contact surface of the two side rails along the drainage groove with a specific slope, thereby realizing continuous, directional and uniform lubrication of each friction pair, significantly reducing the movement resistance and wear, and improving the smoothness, quietness and durability of the sunroof operation.

DETAILED DESCRIPTION

[0036] Embodiment 1, as shown in Figure 10 The low-resistance automobile sunroof guide rail of the application comprises a guide rail frame 1, two main slide rails 11 arranged on the guide rail frame 1, and a bearing block 2 slidingly fitted on the two main slide rails 11.

[0037] Specifically, as shown in Figures 11-12 and Figures 14-16 Each main slide rail 11 comprises, in sequence along the length direction thereof, a roller slide rail 111, a planar slide rail 112, and a lateral guide rail 113; the roller slide rail 111 and the lateral guide rail 113 are respectively located on the left and right sides of the planar slide rail 112, the bearing block 2 is slidingly fitted inside the planar slide rail 112, and a protrusion on the bearing block 2 is slidingly fitted inside the lateral guide rail 113, so as to limit the lateral freedom degree of the bearing block 2 perpendicular to the sliding direction; a limiting groove 21 is formed on a sliding surface of the bearing block 2, a plurality of first springs 22 are fixedly connected to the top inner wall of the limiting groove 21 in a symmetrical structure, and an extrusion block 23 is slidingly fitted inside the limiting groove 21; under the pre-tightening force of the first springs 22, the bottom of the extrusion block 23 always has a tendency to be elastically pressed against the sliding surface of the planar slide rail 112, and the bottom profile of the extrusion block 23 is matched with the shape of an extrusion groove 12 on the roller slide rail 111, so as to be embedded therein.

[0038] In combination with Figures 11-12 and Figures 14-16As shown, the sliding surface of the roller slide rail 111 is provided with an extrusion groove 12. A linear array of integrally formed guide structures are arranged on both sides of the extrusion groove 12. These guide structures can be intermittent grooves used to guide and distribute grease. The extrusion groove 12 is adapted to the shape of the extrusion block 23. Both the roller slide rail 111 and the lateral guide rail 113 have ramped drainage grooves 13 on their sliding surfaces, which communicate with the extrusion groove 12. Specifically, when the bearing block 2 slides along the main slide rail 11, under the continuous action of the first spring 22, the bottom of the extrusion block 23 is always pressed into the extrusion groove 12 on the roller slide rail 111, thus distributing the grease within the groove. The grease is extruded and splits into two streams: one stream is directly spread onto the sliding surface of the planar slide rail 112 by the guide structures on both sides of the extrusion groove 12; the other stream is pressed into the flow groove 13 connected to it. Because the bottom of the flow groove 13 is designed to be inclined upwards towards the sliding surfaces of the roller slide rail 111 and the lateral guide rail 113, the grease rises along the flow groove 13 and is spread onto the sliding contact surfaces of the roller slide rail 111 and the lateral guide rail 113 under capillary action and flow pressure. The extrusion groove 12 is pre-filled with solid or semi-solid grease. When machining the extrusion groove 12, the guide rail frame 1 needs to be pre-treated (e.g., ...). Figure 16 As shown, this enables the machining components to drill and cut the roller slide rail 111, the flat slide rail 112, and the lateral guide rail 113.

[0039] This invention integrates a composite structure of roller slide rail 111, flat slide rail 112, and lateral guide rail 113 into the main guide rail 11, and combines it with a pre-tensioned spring-loaded extrusion block 23 and a built-in grease extrusion groove 12 to construct an automatic lubrication distribution system. This solves the technical problems of traditional sunroof guide rails that rely on manual grease application, resulting in high sliding resistance, jamming noise, and severe wear due to easy lubrication loss. In this design, when the support block 2 slides, the extrusion block 23 can automatically extrude grease, and the grease is accurately distributed to each sliding contact surface through the guide structure and the drainage groove 13, achieving long-lasting lubrication throughout the entire stroke and significantly reducing sliding resistance. At the same time, the cooperation between the lateral guide rail 113 and the extrusion block 23 restricts the lateral freedom of the support block 2, improves sliding stability, and extends the service life of the guide rail and the support block 2.

A top sheet 6113 is fixedly connected to one side of the guide plate 611, a slope 612 is fixedly connected to one side of the limiting plate 69 close to the guide plate 611, a fixed plate 613 is fixedly connected to one side of each driving block 610, a waist-shaped groove 6131 is formed on one side of each fixed plate 613, and a limiting sleeve 614 with a bearing is arranged on one side of each fixed plate 613. The protrusions on the two limiting sleeves 614 are slidably sleeved in the waist-shaped grooves 6131, and the remaining limiting sleeves 614 are fixedly connected to the fixed plates 613.
