Description

Technical Field

[0001] The present application relates to the technical field of sunshade equipment, and in particular to a sliding device and sunshade equipment containing a linear guide rail. Background Art

[0002] The axial direction of the roller tube of the roller blind is fixed. To achieve a windproof effect, fixed guide grooves need to be installed on both sides of the fabric. One end of the fabric is fixed on the roller tube, and the welded zippers on both sides of the fabric are stuck in the guide grooves. The fabric is retracted and released around the radial movement of the roller tube. When the fabric of the roller blind is working up and down, the diameter of the roller blind will change with the retraction and release of the fabric. Then, the position where the fabric falls forms an angle with the contour center of the guide groove, which produces friction, affecting the service life of the windproof roller blind. The existing technology is to set a horizontal rolling device so that it can linearly and adaptively adjust the position of the fabric retraction and release. Because it is a low-speed motion mechanism, the existing technology often ignores the stability of its movement and the friction generated between the various motion mechanisms. When the friction coefficient is large, the horizontal sliding device will lose its adaptive adjustment function and generate unnecessary noise.

[0003] Therefore, the rolling device, as the load-bearing connecting part of the roller blind, needs to be connected to the winding assembly. The existing technology makes the connection too complicated, the accessories are redundant, and the slider of the sliding device is designed to be thin in consideration of the shading and blocking functions, resulting in poor load-bearing capacity. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a sliding device and a sunshade device containing a linear guide rail. A slide groove is arranged on the guide rail to reduce the contact between the side of the follower element and the slide groove. The rotating surface of the follower element is limited in the slide groove, so the shaking is small. The fastener accommodation cavity arranged on the guide rail avoids the friction between the fastener and the guide rail. The gasket is placed on one axial end face of the follower element and one end face of the fixed seat, so that the axial direction of the follower element is completely fixed, and the friction between the fixed seat and the guide rail is also avoided. Since the contact surface between the follower element and the slide groove is small, the friction resistance is very small, and a slight movement can be performed, thereby realizing the positioning of the device. A polygonal hole is arranged on the slider for connecting and carrying the winding assembly. The polygonal hole can support the reaction force generated by the bending moment and torque of the winding assembly. The through hole on the slider is used for positioning and limiting the winding assembly, so that the slider and the winding assembly can be quickly and easily connected.

[0005] A sliding device containing a linear guide rail in an embodiment of the present application includes a guide rail and a slider; wherein: the guide rail includes a first limiting portion, a second limiting portion, a first flange, and a second flange; the slider includes a fixed seat, a first fastener, a second fastener, and a follower element; the fixed seat includes a polygonal hole, a through hole, a first connecting hole, and a second connecting hole.

[0006] The first limiting portion, the second limiting portion, the first flange and the second flange form a slide groove so that the follower element can only slide along the X direction of the slide groove. The first limiting portion, the second limiting portion and the bottom plate of the guide rail form a cavity so that the first fastener does not generate friction with the guide rail.

[0007] The following element is arranged in the slide groove, and the following element is connected and fastened to the first connecting hole and the second connecting hole of the fixing seat through the first fastener and the second fastener.

[0008] The polygonal hole on the fixing seat is used for connection and positioning with shaft parts, and the hole is used for positioning, connection and position constraint of shaft parts.

[0009] In one embodiment, the first limiting portion, the second limiting portion, the first flange and one end surface of the second flange of the guide rail are parallel to each other and perpendicular to the first surface of the guide rail, and the first surface of the guide rail is parallel to the second surface.

[0010] In this embodiment, these arrangements enable the guide rail to form a linear slideway, which can constrain the moving position of the follower element and reduce the friction generated when the moving part is working.

[0011] In one embodiment, one side of the axial surface of the follower element is in contact with the flange of the first fastener, and the other side is in contact with one side of the second fastener, and the other side of the second fastener is in contact with one end face of the fixing seat. After the follower element is connected and fastened to the fixing seat through the fastener, the follower element, the first fastener, and the second fastener, the axial direction of the follower element is fixed, and the radial direction can rotate. The number of gaskets can be increased or decreased according to actual conditions.

[0012] In this embodiment, the fixed seat and the follower element can realize the sliding function after being connected, and the first fastener plays the role of fastening and space adjustment. The first fastener is placed between the fixed seat and the follower element to adjust the space between the follower element, the guide rail, and the fixed seat, so that the fixed seat does not interfere with the guide rail when sliding. It also allows the rotating surface of the follower element to rotate without being affected when the follower element is axially fixed.

[0013] In one embodiment, one end surface of the first connecting hole and the second connecting hole of the fixing seat further includes a flange, and the flange is used to fit with one end surface of the inner ring of the bearing, which can also achieve the above-mentioned effect of reducing friction and connecting and tightening.

[0014] In one embodiment, the follower element is a flange-type structure that can be fixed axially and rotated radially, and its inner and outer rings are not on the same plane. The above-mentioned friction reduction and connection and tightening effects can be achieved by connecting the axial direction and the inner ring with fasteners.

[0015] In one embodiment, the axes of the first connecting hole and the second connecting hole of the fixing seat are parallel and horizontally connected, so that the rotating surfaces of the connected follower elements are in the same plane, allowing the fixing seat to slide linearly.

[0016] In one embodiment, the guide rail is placed horizontally, and correspondingly, the slider is also placed horizontally. When the center of gravity of the winding assembly carried by the slider changes, the follower element will automatically adjust its position on the guide rail due to the traction of gravity.

[0017] In a second aspect, the present application provides a sunshade device, comprising a winding assembly and a sliding device provided by any one of the above items, wherein the sliding device is used to connect the winding assembly of the sunshade device and enable it to have a position adjustment function.

[0018] The sunshade device provided in the second aspect of the present application uses the sliding device provided in the first aspect of the present application to adjust its position. This is because the sliding device provided in the first aspect of the present application has low friction and smooth operation, which improves the reliability of the sunshade device's adaptive position adjustment and can be simply installed with external parts to achieve the functions of bearing and limiting.

[0019] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figure 1 to Figure 7 The present application provides a sliding device containing a linear guide rail, including a guide rail 5 and a slider 1; wherein: the slider 1 includes a fixed seat 6, a follower element 3, a first fastener 7, and a second fastener 9, and the fixed seat 6 includes a first connecting hole 50, a second connecting hole 51, a polygonal hole 52, and a through hole 53.

[0042] The first connection hole 50 and the second connection hole 5 of the fixing seat 6 are used to connect and fasten with the follower element 3, and the through hole 53 and the first through hole 52 are used to connect with pins and shaft parts (pins and shafts refer to the pins and shafts in the sunshade device and the winding components supported by them). The first fastener 7 passes through the follower element 3 and the second fastener 9 and is connected and fastened with the first connection hole 50 and the second connection hole 51 on the fixing seat 6 to form the slider 1. The first fastener 7, the second fastener 9, the inner ring 200 of the follower element 3 and the fixing seat 6 are connected. The first limiting portion 90, the second limiting portion 91, the first flange 70, and the second flange 71 of the guide rail 5 form a linear slide groove 60 so that the bearing 3 can only slide along the X direction of the slide groove 60. The first limiting portion 90 and the second limiting portion 91 of the guide rail 5 and the bottom plate 140 form a receiving cavity 61 to avoid friction between the flange body 75 of the fastener 7 and the guide rail 5.

[0043] The present application provides a sunshade device, including a winding mechanism and the above-mentioned sliding device, the sliding device is used for bearing the winding mechanism and adaptively adjusting the position. Because the sliding device operates stably, has low friction, and can be quickly connected with pins and shaft parts, the friction generated during the operation of the sunshade device of the present application is reduced, so that the sunshade device can normally adaptively adjust the position and has the characteristics of rapid assembly.

[0044] The sunshade device provided in the present application is a rotating mechanism with a winding function for collecting and releasing covering objects, such as roller blinds, ceiling blinds, etc.

[0045] See also Figure 2-Figure 3In a possible implementation, the first limiting portion 90, the second limiting portion 91, the first flange 70, the second flange 71 on the guide rail 5 form a slide groove 60 so that the follower element 3 can only slide in the slide groove 60, and the first limiting portion 91, the second limiting portion 90 and the guide rail bottom plate 140 form a C-shaped groove 61 so that the flange body 75 of the first fastener 7 does not generate friction with the guide rail 5. For example, please refer to Fig.11 In the figure, (a2) and (b2) respectively show the plan view and one side perspective of the guide rail 5, wherein the first surface 500 is parallel to the second surface 501, the third surface 502 coincides with the fourth surface 503 and is perpendicular to the first surface 500, and the fifth surface 504 coincides with the sixth surface 505 and is perpendicular to the first surface 500, so that a straight slide groove 60 can be formed so that the follower element 3 can only slide in the slide groove 60.

[0046] In a possible implementation, the first fastener 7 is a connecting and fastening part with threaded features such as a bolt or a stud. Exemplarily, the first fastener 7 is a bolt.

[0047] In a possible embodiment, the guide rail 5 is made of metal, such as aluminum alloy, iron, stainless steel, etc. For example, the guide rail 5 is made of aluminum alloy, which is extruded by a mold, and can better maintain the straightness of the slide groove 60 and the parallelism of the two sides of the groove, so that the follower element 3 can slide smoothly.

[0048] In a possible embodiment, the fixing seat 6 is made of metal and is provided with a polygonal hole 52 and a through hole 53 for connecting with shaft parts. The polygonal hole 52 serves to support the winding assembly of the sunshade device described in the present application, and can also withstand the reaction force of the bending moment of the winding assembly.

[0049] For example, see Figure 7 , (a1) and (b1) in the figure respectively show a side view of the sliding device and a partial enlarged view of its cross section. For example, the connection between the shaft 100 and the polygonal hole 52 in the figure is a surface connection, the outline size of the shaft 100 is smaller than the outline size of the polygonal hole 52, and a through hole 56 is provided on the shaft 100. After the shaft 100 is placed in the first through hole 52, the split pin 8 passes through the through hole 53 and the through hole 56 respectively and then bends the part so that it will not fall off. In this way, the freedom of movement of the shaft 100 is completely fixed.

[0050] In some embodiments, the follower element 3 is an element that can be axially fixed and radially rotatable, such as a bearing, a cam, a universal ball, etc. Exemplarily, the follower element 3 is a bearing.

[0051] Please look back Figure 1-Figure 6In a possible implementation manner, one side of the axial surface of the inner ring 200 of the follower element 3 is in contact with the flange body 75 of the first fastener 7, and the other side is in contact with the second fastener 9. After the first fastener 7 and the second fastener 9 are connected to the fixing seat 6, the inner ring of the follower element 3 and the axial direction of the follower element 3 are completely fixed, the outer ring 200 of the follower element 3 can rotate, and the number of the second fasteners 9 can be increased or decreased according to actual conditions.

[0052] In a possible embodiment, the second fastener 9 is a washer, a retaining ring, etc., which can be placed between the first fastener 7 and the surface of the connected fixed seat 9 to play the role of separating the working surfaces of the inner and outer rings of the follower element 3, and also prevent the first fastener 7 from loosening. It also plays a role in space adjustment, while avoiding friction between the follower element 3 and the fixed seat 6, and also avoiding friction between the fixed seat 6 and the guide rail 5.

[0053] In a possible implementation, the follower element 3 is a bearing with a flange structure, and its inner and outer rings are not on the same plane. The above-mentioned effect of reducing friction can also be achieved by tightening the first fastener 7 in its axial direction.

[0054] In a possible implementation manner, the surfaces of the first connection hole 50 and the second connection hole 51 of the fixing base 6 have flange structures, see Fig. 9 , Fig.10 , respectively show other embodiments of the fixing seat 6, wherein the outer end surfaces of the first connecting hole 50 and the second connecting hole 51 are provided with a first flange 80 and a second flange 81, which can replace the second fastener 9 and also play the role of reducing friction. For the sake of brevity, no further description is given.

[0055] In a possible implementation, the first connection hole 50 and the second connection hole 51 of the fixing seat 6 are connection holes with connection and fastening functions, such as threaded holes, pin holes, etc., and illustratively, the first connection hole 50 and the second connection hole 51 are threaded holes. The axes of the first connection hole 50 and the second connection hole 51 are kept parallel and horizontally connected, so that the rotation surface of the follower element 3 can be on the same plane after being connected and fastened, that is, the slider 1 can slide linearly.

[0056] In some embodiments, the number of the first connection hole 50 and the second connection hole 51 is at least one, or may be several. In this way, the number of the follower elements is at least two, and the relationship between two or more follower elements 3 and the slide groove is a line and a plane, so that when the fixed seat 6 is subjected to the torque generated by the rotation of the shaft 100, at least one follower element 3 can support the reaction force of the torque, so that the fixed seat 6 is not rotated.

[0057] In some embodiments, when the guide rail is horizontal or nearly horizontal, the slider 1 is stationary on the guide rail 5. When the center of gravity of the slider 1 changes, the bearing 3 will automatically adjust its position on the guide rail 5 under the traction of gravity. Fig.12 As shown, the figure shows the appearance of the assembly of some parts of the sunshade device as a windproof roller blind. In the figure, the winding component 520 is connected to the fixed seat 1, and a covering 521 is set on the winding component 521. When the winding mechanism winds up the covering 521, the center of gravity of the covering 521 will change. The change in the center of gravity generates a traction force to make the slider 1 move in the X direction.

[0058] In some embodiments, the first load platform 160 and the second load platform 161 of the guide rail 5 have the functions of position constraint and support. Fig.13 As shown in the figure, a cross-sectional schematic diagram of the assembly of some parts of the sunshade device as a windproof roller blind is shown, wherein the second bearing platform 161 of the guide rail 5 is carried on the third fastener 170, and the positions of the first bearing platform 160 and the second bearing platform 161 in the Z direction are constrained by the mounting bracket 171. The first bearing platform 160 and the second bearing platform are connected with the mounting bracket 171 by clearance fit, and such a setting reduces the need for other parts to compensate for the gap between them and the mounting bracket to reduce shaking due to excessive clearance, plays a role in reducing matching parts, and is easy to install.

[0059] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
