Description

Technical Field

[0001] The present application relates to the technical field of sunshade equipment, and specifically to a linear guide rail and sunshade equipment. Background Art

[0002] The roller tube of the roller blind in the sunshade device is fixed, and the roller tube that winds the fabric will become larger or smaller as the fabric is retracted or released, so that the position of the fabric perpendicular to the roller tube will change. Therefore, a sliding mechanism needs to be set up so that it can make reciprocating motion when the fabric is retracted and released to adjust the position of the fabric. The existing technology often does not take into account the friction generated during its movement and the smoothness of its operation. Utility Model Content

[0003] The present application provides a linear guide rail and a sunshade device. The linear guide rail has the characteristics of reducing friction and running smoothly. The present application specifically includes the following solutions:

[0004] A linear guide rail of an embodiment of the present application includes a first surface, a second surface, a third surface, a fourth surface, a fifth surface, a sixth surface, a seventh surface, an eighth surface, a ninth surface, a tenth surface, an eleventh surface, a twelfth surface, a first flange, a second flange, a third flange, a fourth flange, a fifth flange, a sixth flange, a first bearing platform, a second bearing platform, a first reinforcing rib, and a second reinforcing rib.

[0005] In one embodiment, the first surface is a vertical plane, the second surface is a horizontal plane, the third surface is parallel to the second surface and perpendicular to the first surface, the fourth surface coincides with the fifth surface and is perpendicular to the third surface, the sixth surface coincides with the seventh surface and is perpendicular to the third surface, the eighth surface is parallel to the first surface, and the ninth surface is parallel to the tenth surface and perpendicular to the eighth surface.

[0006] In this embodiment, the second surface, the fourth surface, the seventh surface, the sixth surface, the third surface, and the fifth surface form a linear cavity for the sliding element to perform linear motion. Because they are parallel or perpendicular to each other, this ensures that the sliding element can work smoothly.

[0007] In one embodiment, the eleventh surface coincides with the twelfth surface and is perpendicular to the tenth surface.

[0008] In this embodiment, the eleventh surface, the tenth surface, and the eighth surface form a fifth flange, and the twelfth surface, the ninth surface, and the eighth surface form a sixth flange for connection and fastening, which plays the role of positioning, limiting and supporting, and is convenient for installation.

[0009] In one embodiment, the heights of the first flange and the second flange are lower than the heights of the third flange and the fourth flange, and the distances between the fourth surface, the fifth surface and the first surface form a cavity for placing a fastener.

[0010] In this embodiment, the heights of the first flange and the second flange are lower than the heights and bottoms of the third flange and the fourth flange, and the heights of the third flange and the fourth flange are smaller than the radius of the sliding element, thereby reducing the surface-to-surface contact between them and the sliding element, and reducing the friction generated by the sliding element during operation. After the cavity between the fourth surface, the fifth surface and the first surface is used for connecting and tightening the fastener to the sliding element, the flange of the fastener will not interfere with the guide rail, thereby further reducing the friction between the sliding element and the guide rail.

[0011] In one embodiment, the first reinforcing rib is connected to the first bearing platform, and the second reinforcing rib is connected to the second bearing platform. The first reinforcing rib and the second reinforcing rib serve to increase the supporting force of the first bearing platform and the second bearing platform in the vertical direction.

[0012] In a second aspect, the present application provides a sunshade device, comprising a sliding element and a guide rail provided by any one of the above items, wherein the guide rail is used for constraining and supporting the movement of the sliding element.

[0013] The sunshade device provided in the second aspect of the present application utilizes the guide rail provided in the first aspect of the present application for dynamic constraint and support, because the guide rail provided in the first aspect of the present application has low friction and runs smoothly, thereby increasing the service life of the sunshade device.

[0014] Additional aspects and advantages of the present application will be given in part in the following description, and in part will become apparent from the following description, or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0028] For the convenience of description, the direction of the edge 501 of the guide rail is defined as the Y direction (eg Figure 1 The vertical direction of the paper shown in FIG. 5 may also be referred to as the Y-axis direction). The direction perpendicular to the edge 501 and parallel to the direction of the edge 509 is the X-direction (eg Figure 1 The horizontal direction of the paper shown in FIG. 5 is also referred to as the X-axis direction), and the direction perpendicular to the edge 501 and perpendicular to the edge 509 is the Z direction (e.g. Figure 1 The direction perpendicular to the paper surface shown in the figure may also be referred to as the Z-axis direction). Similarly, the definitions of the X, Y, and Z directions also apply to the drawings to be described later. If not specifically stated, the X, Y, and Z directions include their positive and negative directions. It should be noted that the above definitions of the X, Y, and Z directions are only for the convenience of describing the positional relationship and connection relationship between the various components in the embodiments of the present application, and should not be understood as limiting the embodiments of the present application.

[0029] See also Figure 1 to Figure 5 A linear guide rail includes: a first surface 501, a second surface 502, a third surface 503, a fourth surface 504, a fifth surface 505, a sixth surface 506, a seventh surface 507, an eighth surface 508, a ninth surface 509, a tenth surface 510, an eleventh surface 511, a twelfth surface 512, a first flange 61, a second flange 62, a third flange 63, a fourth flange 64, a first reinforcing rib 71, a second reinforcing rib 72, a first bearing platform 81, and a second bearing platform 82.

[0030] The first surface 501 is a vertical plane parallel to the Y direction, the second surface 502 is a horizontal plane parallel to the X direction, the third surface 503 is parallel to the second surface 502 and perpendicular to the first surface 501, the fourth surface 504 coincides with the fifth surface 505 and is perpendicular to the third surface 503, the sixth surface 506 coincides with the seventh surface 507 and is perpendicular to the third surface 503, the eighth surface 508 is parallel to the first surface 501, and the ninth surface 509 is parallel to the tenth surface 510 and perpendicular to the eighth surface 508.

[0031] In some embodiments, the second surface 502, the fourth surface 504, the seventh surface 507, the sixth surface 506, the third surface 503, and the fifth surface 505 form a linear cavity 90 for the sliding element 91 to perform linear motion. Because they are parallel or perpendicular to each other, and the linear cavity 90 and the follower element 91 are connected by a profile, it can ensure that the sliding element 91 can work smoothly. The sliding element is a part that can be axially connected and fastened, and can rotate axially, such as a bearing, a cam, a universal ball, etc. For example, see Figure 2 In the figure, the sliding element 91 is a bearing, and the outer ring of the sliding element 91 is in contact with the linear cavity 90. The six surfaces of the linear cavity 90 form a retainer, which limits the rotation freedom of the sliding element 91 around the X, Y, and Z directions, and limits its displacement freedom in the X and Y directions, and it can only slide along the Z direction.

[0032] Furthermore, the heights of the first flange 61, the second flange 62, the third flange 63, and the fourth flange 64 (reference surface for the height: the first flange is based on the third surface 503, and the second flange is based on the second surface 502) are smaller than the radius of the sliding element 91, and the heights of the first flange 61 and the second flange 62 are smaller than the heights of the third flange 63 and the fourth flange 64. This allows the linear cavity 91 to act as a retainer while also reducing the surface-to-surface contact between the linear cavity 91 and the sliding element 91, thereby reducing friction.

[0033] Furthermore, a second cavity 92 is formed between the fourth surface 504 and the fifth surface 505 and the first surface 501 so that the fastener 70 will not generate friction with the first flange 61, the second flange 62 and the first surface 501 after being connected. Figure 1-Figure 4 , illustratively, Figure 2 The middle fastener 70 is a bolt, which passes through the inner ring 99 of the sliding element 90 and the slider 98 to be fastened, and the flange of the fastener 70 is received in the second cavity 92, thus avoiding friction between the fastener 70 and the guide rail.

[0034] In some embodiments, the first support platform 81 and the second support platform 82 provide support for the sliding element 90 in the Y direction, wherein the first reinforcement rib 71 is connected to the first support platform 51, and the second reinforcement rib 72 is connected to the second support platform 52, so that the first support platform 81 and the second support platform 82 can withstand a larger load.

[0035] In some embodiments, the guide rail is made of metal such as aluminum alloy, stainless steel, iron, etc. For example, the guide rail is made of aluminum alloy, which is prepared by die extrusion. This can well ensure the verticality and parallelism between the various surfaces of the guide rail, so that it has the function of linear guidance.

[0036] See also Figure 5 and Figure 6 , the figure shows an exemplary assembly diagram and cross-sectional diagram of some parts of a sunshade device for a windproof roller blind. The guide rail is used to support and constrain the movement of the sliding element 90. In the figure, the sliding element 90 can only move in the Z direction in the guide rail. The sunshade device described in the present application is a device such as a roller blind, a ceiling curtain, etc. that can be rotated to collect and release a covering material 521 (such as fabric, TPU) and play a role in sunshade or shielding. For example, in the figure, the covering material 521 is a fabric, the roller tube 520 is an aluminum or iron roller, and the fifth flange 45 and the sixth flange 46 of the guide rail are arranged in the installation code 522. After the installation code is connected to the guide rail, the guide rail is completely fixed in the X direction, and the ninth surface of the second flange 46 is carried on the bolt 600, so that the guide rail can be adjusted in height in the Y direction. Therefore, the guide rail has the functions of positioning, limiting and supporting.

[0037] The above is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the protection scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
