[0002] A guide rail is a groove or ridge made of metal or other materials, which can bear, fix, guide a moving device or equipment and reduce its friction. Currently, there are various forms of guide rails in the prior art, such as: ball guide rails, dovetail groove guide rails, etc.

[0003] Among them, as Figure 1 and Figure 2 shown, the ball guide rail includes: a fixed guide groove 110, a moving guide rail 120, a moving guide groove 130, a moving guide rail 140, a first-stage telescopic plate 150, and a second-stage telescopic plate 160; the opening of the groove of the fixed guide groove 110 faces the side to accommodate the moving guide rail 120 from the side, and the other side of the fixed guide groove 110 is used to be fixed to a support member to support the entire ball guide rail; the moving guide rail 120 is clamped into the groove of the fixed guide groove 110, and there are balls on both the upper and lower sides of the moving guide rail 120, so as to realize the rolling of the moving guide rail 120 in the fixed guide groove 110; one side of the first-stage telescopic plate 150 is fixed to the side of the moving guide rail 120 away from the fixed guide groove 110, and the first-stage telescopic plate 150 extends in a direction away from the moving guide rail 120; one side of the moving guide groove 130 is fixed to the lower surface of the first-stage telescopic plate 150, and the opening of the groove of the moving guide groove 130 faces downward to accommodate the moving guide rail 140 from below; the moving guide rail 140 is clamped into the groove of the moving guide groove 130, and there are balls on both the upper and lower sides of the moving guide rail 140, so as to realize the rolling of the moving guide rail 140 in the moving guide groove 130; one side of the second-stage telescopic plate 160 is fixed to the lower surface of the moving guide rail 140, and the other side of the second-stage telescopic plate 160 extends in a direction away from the moving guide rail 120.

[0004] In addition, as Figure 3 and Figure 4As shown in the figure, the dovetail groove guide rail includes: a fixed guide groove 310, a moving guide rail 320, a moving guide groove 330, a moving guide rail 340, a first-stage telescopic plate 350, and a second-stage telescopic plate 360; the opening of the dovetail groove of the fixed guide groove 310 faces the side to accommodate the moving guide rail 320 from the side, while the other side of the fixed guide groove 310 is used to be fixed to the support member, thereby supporting the entire dovetail groove guide rail; the moving guide rail 320 is clamped into the dovetail groove of the fixed guide groove 310, thereby realizing the sliding of the moving guide rail 320 in the fixed guide groove 310; one side of the first-stage telescopic plate 350 is fixed to the side of the moving guide rail 320 away from the fixed guide groove 310, and the first-stage telescopic plate 350 extends in the direction away from the moving guide rail 320; one side of the moving guide groove 330 is fixed to the lower surface of the first-stage telescopic plate 350, and the opening of the dovetail groove of the moving guide groove 330 faces downward to accommodate the moving guide rail 340 from below; the moving guide rail 340 is clamped into the dovetail groove of the moving guide groove 330, thereby realizing the sliding of the moving guide rail 340 in the moving guide groove 330; one side of the second-stage telescopic plate 360 is fixed to the lower surface of the moving guide rail 340, and the other side of the second-stage telescopic plate 360 extends in the direction away from the moving guide rail 320.

[0005] Due to the rolling clearances between the fixed guide groove 110 and the moving guide rail 120, and between the moving guide groove 130 and the moving guide rail 140 of the existing ball guide rail, the ball guide rail gradually sags downward from the support member fixedly connected to the fixed guide groove 110 to the direction away from the support member. Similarly, due to the sliding clearances between the fixed guide rail 310 and the moving guide rail 320, and between the moving guide groove 330 and the moving guide rail 340 of the existing dovetail groove guide rail, the dovetail groove guide rail gradually sags downward from the support member fixedly connected to the fixed guide groove 130 to the direction away from the support member. In addition, due to the sagging of the guide rail, when running a relatively long distance (for example: 1 meter), a jamming phenomenon will occur, reducing the user experience. In addition, in the case of a large stroke requirement, the ball guide rail also has the problems of difficult manufacturing and too high cost.

[0006] Therefore, how to avoid the sagging and jamming phenomena of the guide rail to improve the user experience is a technical problem that needs to be solved by those skilled in the art at present. Summary of the Invention

[0028] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. In addition, spatial relationship terms such as "above", "upper", "below", "lower" are used to facilitate the description to explain the positional relationship between two components. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0029] As Figure 5 and Figure 6 , the present application provides a roller profile guide rail, including: a fixed guide rail 510, a moving guide rail 520, and a composite guide rail 530.

[0030] Among them, the fixed guide rail 510 has a fixed guide rail groove 511 with an opening facing upward for accommodating the moving guide rail 520 and the composite guide rail 530; the fixed guide rail 510 also has a fixed guide rail mounting hole 512 with an opening facing downward for connecting with a support member to fix the roller profile guide rail.

[0031] Specifically, the fixed guide rail mounting hole 512 is located on the lower surface of the fixed guide rail 510, and the fixed guide rail mounting hole 512 is far from the extension axis of the fixed guide rail 510. That is to say, as Figure 6 shown, the fixed guide rail mounting hole 512 is located in the left area on the lower surface of the fixed guide rail 510. To ensure the stable fixation of the fixed guide rail 510 and the support member, a plurality of fixed guide rail mounting holes 512 are evenly distributed on the lower surface of each fixed guide rail 510, and the arrangement direction of these fixed guide rail mounting holes 512 is the same as the extension direction of the fixed guide rail 510. By having the fixed guide rail mounting hole 512 on the lower surface of the fixed guide rail 510, side fixation is avoided, ensuring the specified motion mode.

[0032] The fixed guide rail groove 511 is located on the upper surface of the fixed guide rail 510, and its extension direction is the same as the extension axis of the fixed guide rail 510, and the fixed guide rail groove 511 and the fixed guide rail mounting hole 512 are offset from each other. That is to say, as Figure 6 shown, the fixed guide rail groove 511 is located in the right area on the upper surface of the fixed guide rail 510. In addition, the cross-sectional width of the left area is smaller than that of the right area, and the left area and the right area do not overlap. In the present application, the moving guide rail 520 and the composite guide rail 530 can be supported by the fixed guide rail groove 511 with an opening facing the direction, thereby avoiding the sag phenomenon caused by the accumulation of sliding gaps between the moving guide rail 520 and the fixed guide rail 510 and between the moving guide rail 520 and the composite guide rail 530.

[0033] On the above basis, the bottom surface of the fixed guide groove 511 has a partition wall 513 extending upward, so as to divide the fixed guide groove 511 into a moving branch installation groove and a composite branch installation groove with the same extension axis as the extension axis of the fixed guide rail 510. The moving branch installation groove is used to accommodate the moving branch of the moving guide rail 520, and the composite branch installation groove is used to accommodate the composite branch of the moving guide rail 520. And, the composite branch installation groove is far from the extension axis of the fixed guide rail 510, that is to say, as Figure 6 shown, the composite branch installation groove is located in the right area of the upper surface of the fixed guide rail 510, and the moving branch installation groove is located in the middle area of the upper surface of the fixed guide rail 510.

[0034] In order to clamp the moving roller 521 of the moving guide rail 520 into the moving branch installation groove, the upper surface of the fixed guide rail 510 extends into the moving branch installation groove by a predetermined distance, and the upper end of the partition wall 513 extends into the moving branch installation groove by a predetermined distance, so that the size of the opening of the moving branch installation groove is smaller than its internal size, so as to clamp the moving roller 521 of the moving guide rail 520 into the moving branch installation groove. In addition, since the upper surface of the fixed guide rail 510 is higher than the upper end of the partition wall 513, a limiting protrusion 514 protrudes into the moving branch installation groove at a part of the side wall of the moving branch groove close to the fixed guide rail installation hole 512. The limiting protrusion 514 faces the moving roller 521 of the moving guide rail 520 to limit the position of the moving roller 521 above.

[0035] In addition, in order to facilitate the installation of the composite guide rail 530 into the composite branch installation groove, the opening of the composite branch installation groove extends from the upper surface of the fixed guide rail 510 to the upper half of its side wall, so that the opening of the composite branch installation groove is larger, which is convenient for installing the composite guide rail 530 into it.

[0036] In order to better limit the position of the moving roller 521 of the moving guide rail 520, the bottom surface of the moving branch installation groove has a limiting protrusion 515 protruding upward, and the limiting protrusion 515 is located in the middle of the bottom surface of the moving branch installation groove, so as to form moving roller grooves 516 with the same extension axis as the extension axis of the fixed guide rail 510 on both sides of the bottom surface of the moving branch installation groove, thereby restricting the moving roller 521 of the moving guide rail 520 in the moving roller grooves 516.

[0037] The moving branch of the moving guide rail 520 extends from top to bottom into the moving branch installation groove, and the moving roller 521 is installed on the moving branch to roll in the moving branch installation groove through the moving roller 521. Preferably, it rolls in the moving roller groove 516 in the moving branch installation groove to realize the relative movement between the moving guide rail 520 and the fixed guide rail 510. Specifically, moving rollers 521 are installed on both sides of the moving branch of the moving guide rail 520, and each moving roller 521 on each side is stuck in the moving roller groove 516 opposite to it. The installation of the moving roller 521 is ensured by the geometric space structure of the fixed guide rail 510 and the moving guide rail 520 described above.

[0038] In addition, the composite branch of the moving guide rail 520 extends from top to bottom into the composite branch installation groove, and the part of the composite branch in the composite branch installation groove has a composite roller guide groove 522 with an opening facing away from the moving branch. That is to say, as Figure 6 shown, the opening direction of the composite roller guide groove 522 faces the right side of the fixed guide rail 510 to accommodate the composite roller 531 of the composite guide rail 530. Preferably, the size of the opening of the composite roller guide groove 522 is smaller than its internal size, so as to prevent the composite roller 531 from detaching from the composite roller guide groove 522 through the opening of the composite roller guide groove 522.

[0039] The composite guide rail 530 extends from top to bottom into the composite branch installation groove and bends into the composite roller guide groove 522 in the composite branch installation groove. The composite roller 531 is installed on the composite branch to roll in the composite roller guide groove 522 through the composite roller 531, so as to realize the relative movement between the composite guide rail 530 and the moving guide rail 520. Since the composite guide rail 530 extends from top to bottom and can extend into the composite roller guide groove 522 only after bending in the composite branch installation groove, the force arm of the composite guide rail 530 is short, resulting in a smaller tendency for the composite guide rail 530 to sag downward.

[0040] On the above basis, the fixed guide rail 510, the moving guide rail 520 and the composite guide rail 530 in the present application are all aluminum alloy extrusion profiles. Since the volumes of the fixed guide rail 510 and the moving guide rail 520 are large and have a great influence on the overall weight of the roller profile guide rail, in order to reduce the weights of the fixed guide rail 510 and the moving guide rail 520, it is preferred in the present application that the fixed guide rail 510 has a first weight reduction cavity, a second weight reduction cavity, a third weight reduction cavity and a fourth weight reduction cavity. The first weight reduction cavity and the second weight reduction cavity are distributed on both sides of the fixed guide rail installation hole 512. The third weight reduction cavity is distributed inside the limit protrusion 515 on the bottom surface of the moving branch installation groove. The fourth weight reduction cavity is distributed inside the partition wall 513 in the fixed guide rail groove 511. The moving guide rail 520 has a fifth weight reduction cavity, and the fifth weight reduction cavity is distributed inside the moving branch extending into the moving branch installation groove.

[0041] Due to numerous uncertainties in the production process of aluminum alloy extrusion profiles, flat rollers with the least constraints are selected as the moving rollers 521 and the composite rollers 531 in this application to reduce the obstacles encountered by the moving rollers 521 and the composite rollers 531 during movement. Additionally, the gap between the flat roller and the aluminum alloy extrusion profile in this application is 1 millimeter, which is comprehensively calculated based on the length of the aluminum alloy extrusion profile and the manufacturing error of the aluminum alloy extrusion profile, and has been verified qualified through tests. On this basis, external mounting holes, preferably screw holes, are provided at the upper ends of the moving guide rail 520 and the composite guide rail 530 to be fixedly connected to the connecting piece through the external mounting holes.

[0042] When the roller profile guide rail in this application is in use, generally two relatively arranged roller profile guide rails are fixed on the support member. As an example, when applying the roller profile guide rail to a roof tent, as Figure 7 shown, a part of one bottom edge of the roof tent 710 is fixed to the composite guide rail 530 of a roller profile guide rail, another part of this bottom edge is fixed to the moving guide rail 520 of this roller profile guide rail, and the remaining part of this bottom edge is fixed to the fixed guide rail 510 of this roller profile guide rail. A part of the other bottom edge of the roof tent 710 is fixed to the composite guide rail 530 of another roller profile guide rail, another part of this other bottom edge is fixed to the moving guide rail 520 of another roller profile guide rail, and the remaining part of this other bottom edge is fixed to the fixed guide rail 510 of another roller profile guide rail.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
