[0002] This application claims priority to Chinese patent application No. 202410267363.5 filed on March 8, 2024, and cites the contents disclosed in the above patent application as part of this application. Technical Field

[0003] The present disclosure relates to the technical field of skylight structures, and in particular to a sunshade guide rail and an assembly method thereof. Background Art

[0004] Car sunroofs effectively circulate air inside the vehicle, increasing the intake of fresh air and providing a healthy and comfortable experience for passengers. They also offer a wider field of vision. Compared to traditional car sunroofs, the increasingly popular panoramic sunroofs are larger in size, further enhancing the view from the top of the car, but also significantly increasing the amount of light entering the vehicle. To address the sunshade issue, existing panoramic sunroofs with opening functions typically come with built-in sunshades.

[0005] Guide rails are a crucial component of existing automotive rear sunroof blinds. As shown in Figures 1 and 2, existing guide rails typically consist of a side rail, a slider rail, a flexible shaft recovery rail, and a mounting surface that locks with bolts. This structure enables the slider to slide within the guide rails.

[0006] The existing guide rail structure can only meet the needs of traditional sunshades with flexible shafts and is not suitable for the new application structure of direct-drive sunshades.

[0007] Therefore, it is necessary to propose a sunshade guide rail to adapt to the direct-drive sunshade. Summary of the Invention

[0008] In response to the defects of the existing technology, the embodiments of the present invention provide a sunshade guide rail and an assembly method thereof, which are suitable for direct-drive sunshades. The sunshade guide rail has a simple overall structure, high assembly efficiency and high operational reliability.

[0009] The specific technical solutions of the embodiments of the present disclosure are:

[0010] A sunshade guide rail, the sunshade guide rail comprising: a guide rail body extending along a longitudinal length direction, the guide rail body having a relative inner side and outer side along a first direction in a cross section, the guide rail body being provided with a first running track and a second running track for installing a synchronous belt at a position close to the outer side of the guide rail body; the first running track and the second running track being arranged at intervals in the upper and lower directions along a second direction perpendicular to the first direction, the guide rail body being provided with a third running track for installing a sunshade edge strip near the inner side of the guide rail body, a guide structure for installing a slider being formed in the guide rail body, the guide structure comprising a limiting portion capable of limiting the slider in the first direction.

[0011] A sunshade guide rail assembly method is applied to the sunshade guide rail described above; the sunshade guide rail assembly method comprises:

[0012] Arranging a pre-fixing portion at a predetermined position on the sunshade guide rail to pre-assemble the glass and the sunshade guide rail; and

[0013] Adhesive is injected into a predetermined assembly gap formed between the glass and the sunshade guide rail, and the adhesive can form a predetermined bonding structure.

[0014] The technical solution disclosed in this disclosure has the following significant beneficial effects:

[0015] This application provides a new sunshade guide rail that can be pre-fixed to the glass by using a fixing portion (such as double-sided tape) and then pouring an adhesive (such as PU glue) to complete the fixation of the guide rail to the glass. Compared with the existing method of fixing with screws and embedded nuts, the overall structure is simple and the assembly efficiency is high.

[0016] The guide rail body of the sunshade guide rail forms a first running track and a second running track for installing a synchronous belt, a third running track for installing a sunshade edge strip, and a guide groove for installing the slider through an ingenious design of the structure, which can meet the functional requirements of a direct-drive sunshade.

The terms used herein in the specification of this application are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] The present disclosure provides a sunshade guide rail and an assembly method thereof, which are suitable for a direct-drive sunshade. The sunshade guide rail has a simple overall structure, high assembly efficiency, and high operational reliability.

[0033] Please refer to Figures 1 to 9 as a whole. A sunshade guide rail is provided in the embodiment of the application specification. The sunshade guide rail may include: a longitudinally extending guide rail body 100, wherein the cross section of the guide rail body 100 has relative inner and outer sides along the first direction Y, and near the outer side of the guide rail body 100, the guide rail body 100 is provided with a first running track 101 and a second running track 102 for installing the synchronous belt 300; the first running track 101 and the second running track 102 are arranged at intervals in the upper and lower directions along the second direction Z perpendicular to the first direction Y, and near the inner side of the guide rail body 100, the guide rail body 100 is provided with a third running track 103 for installing the sunshade edge strip 602.

[0034] The guide rail body 100 is provided with a guide structure for mounting the slider 200. The guide structure includes a limiting portion capable of limiting the position of the slider 200 in the first direction Y. The guide structure as a whole can be in the form of a guide groove; the limiting portion can be in the form of a limiting groove 104, or can be formed by an internal structure provided in the guide rail body 100.

[0035] In some embodiments, when the limiting portion is in the form of a limiting groove 104, the limiting groove 104 can be connected to at least the third running track 103 and the first running track 101, and the limiting groove 104 cooperates with the third running track 103 and the first running track 101 to form a guide groove for installing the slider 200.

[0036] The guide rail body 100 of the sunshade guide rail forms a first running track 101 and a second running track 102 for installing the synchronous belt 300, a third running track 103 for installing the sunshade edge strip 602, and a guide groove for installing the slider 200 through the ingenious design of the structure, which can meet the functional requirements of the direct-drive sunshade.

[0037] In the embodiment of the present application, the sunshade guide rail may include a guide rail body 100 extending in a longitudinal direction. The extension direction of the guide rail body 100 may vary depending on the curvature of the sunroof of the vehicle in which it is used, and this application does not make any specific restrictions here. Generally, the guide rail body 100 extends as a whole along the direction X of vehicle travel.

[0038] The guide rail body 100 is an integrally formed structure. Specifically, the guide rail body 100 can be integrally formed by injection molding. When the guide rail body 100 is integrally formed by injection molding, the weight of the guide rail body 100 can be reduced, and the production cost and difficulty of the guide rail body 100 can be reduced.

[0039] In the embodiment of the present application, the guide rail body 100 is provided with a first running track 101 and a second running track 102 arranged at intervals in the upper and lower parts through a partition 110, wherein the first running track 101 is used to install the slider 200 and cooperate with the transmission of the synchronous belt 300, and the second running track 102 is used to install the synchronous belt 300. The structure of the above-mentioned guide rail body 100 can cleverly separate the synchronous belt 300 up and down, so that the synchronous belt 300 can not interfere with each other and meet the two cloth-discharging methods of the upper and lower cloth-discharging of the sunshade respectively.

[0040] To restrict the movement of the slider 200 in the first direction Y and prevent it from falling out of the guide rail body 100 during use, a limiting slot 104 is provided within the guide rail body 100. A corresponding engagement portion 202 is provided on the slider 200 to engage with the limiting slot 104. When the engagement portion 202 of the slider 200 engages with the limiting slot 104, the movement of the slider 200 in the first direction Y is constrained.

[0041] The guide rail body 100 is also provided with a third running track 103 for installing the sunshade edge strip 602. The slider 200 has a hook extending into the third running track 103. The sunshade edge strip 602 can be provided with an edge strip hole. After the hook cooperates with the sunshade through the edge strip hole, the sunshade can move under the drive of the slider 200.

[0042] As shown in FIG1 , the guide rail provided in the embodiment of the present application is applied to a direct-drive sunshade. Specifically, during installation, pulleys 310 (gears) are fixed to the front and rear ends of the sunshade guide rail. One side of the synchronous belt 300 (which can be an open or closed belt) is clipped into the open slot (e.g., C-shaped) of the slider 200 and installed in the first running track 101. The other side is placed in the second running track 102. The edge strip holes on the sunshade edge strip 602 are inserted into the fixing posts of the synchronous belt 300, and then inserted into the third running track 103.

[0043] Please refer to Figure 9. When the sunshade needs to be opened or closed, the driving source drives the gear to move, the gear movement drives the synchronous belt 300 to move, the synchronous belt 300 drives the slider 200 to move, and the slider 200 can drive the side strip 602 to move, so that the curtain 603 fixed to the side strip 602 moves, thereby completing the opening and closing of the sunshade. Among them, the driving source can be a motor. Of course, the driving source is not limited to the motor, and can also be achieved manually. When achieved manually, the opening and closing transmission path of the sunshade is different from the transmission path of the above-mentioned motor. It is mainly driven by the pull rod to drive the slider 200, the slider 200 drives the synchronous belt 300, and the synchronous belt 300 drives the gear to move.

[0044] In an embodiment of the present application, the synchronous belt 300 drives the slider 200 to move by establishing a transmission engagement relationship between the synchronous belt 300 and the slider 200. Specifically, the slider 200 is provided with an engaging portion 202 that engages with the synchronous belt 300, and the engaging portion 202 and the synchronous belt 300 are in transmission engagement within the first running track 101. The first running track 101 is provided with the slider 200 and the synchronous belt 300, and the second running track 102 is provided with the synchronous belt 300. Along the second direction Z, the first running track 101 is located above the second running track 102, or below the second running track 102. In the second direction Z, the track depth of the first running track 101 is greater than the track depth of the second running track 102. The slider 200 is provided with an engaging portion that engages with the synchronous belt 300, and the engaging portion and the synchronous belt 300 are in transmission engagement within the first running track 101.

[0045] In the embodiments of the present application, the guide groove for mounting the slider 200 can be formed by the cooperation of multiple parts, thereby limiting the position of the slider 200. Specifically, the guide groove can be formed by the cooperation of the limiting groove 104, the third running track 103, and the first running track 101. The specific shape and structure of the slider 200 are not specifically limited in this application.

[0046] Overall, the present application provides a sunshade guide rail adapted for a direct-drive sunshade, which has a simple overall structure, high assembly efficiency, and high operational reliability.

[0047] The present application will be described in detail below with reference to specific drawings and implementation methods.

[0048] 1, 3, 4 and 5, the present application provides an embodiment of a direct-drive sunshade curtain with a bottom-out cloth-discharging method. 1, 2, 6 and 7, the present application provides an embodiment of a direct-drive sunshade curtain with a top-out cloth-discharging method.

[0049] As shown in Figures 3 and 4, when the sunshade is in a cloth-discharging mode from the bottom, the guide rail body 100 includes an upper guide rail surface 111 and a lower guide rail surface 112 relative to each other along the second direction Z, and a connecting surface is provided between the upper guide rail surface 111 and the lower guide rail surface 112, and a partition 110 is provided on the connecting surface, and the partition 110 cooperates with part of the connecting surface and part of the lower guide rail surface 112 to form the first running track 101, and the partition 110 cooperates with part of the connecting surface and part of the upper guide rail surface 111 to form the second running track 102.

[0050] In this embodiment, the first running track 101 and the second running track 102 can be arranged vertically along the second direction Z. The first running track 101 can be located below the second running track 102, and the two are separated by a partition 110 to prevent interference with the synchronous belt 300. Since the slider 200 and the synchronous belt 300 need to be installed in the first running track 101, and the second running track 102 is only used to install the synchronous belt 300, the cross-sectional dimensions of the first running track 101 (particularly the track depth dimension along the second direction Z) are greater than the cross-sectional dimensions of the second running track 102.

[0051] Overall, the guide rail body 100 has an upper guide rail surface 111 and a lower guide rail surface 112 that face each other, as well as a connecting surface connecting the upper guide rail surface 111 and the lower guide rail surface 112. The three surfaces cooperate to form the main portion of the rail body. A separator 110 is provided on the connecting surface, located between the upper guide rail surface 111 and the lower guide rail surface 112. The separator 110 can cooperate with a portion of the connecting surface and a portion of the lower guide rail surface 112 to form the first running track 101. The separator 110 can also cooperate with a portion of the connecting surface and a portion of the upper guide rail surface 111 to form the second running track 102.

[0052] Specifically, the partition 110 can be a baffle having a certain thickness and arranged along the longitudinal extension direction of the guide rail body 100. In the cross section of the guide rail body 100, one end of the baffle is connected to the connecting portion, and the other end can be formed with a certain upward bend, thereby limiting the position of the synchronous belt 300 located above the second running track 102.

[0053] Of course, the specific shape and structure of the partition 110 are not limited to the above examples. Technical personnel in the relevant field may make other changes based on the technical essence of this application. However, as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0054] Please refer to Figures 6 and 7. When the sunshade is in the upper cloth-discharging mode, the guide rail body 100 includes an upper guide rail surface 111 and a lower guide rail surface 112 relative to each other along the second direction Z. A partition 110 bent at a predetermined angle is provided between the upper guide rail surface 111 and the lower guide rail surface 112. Part of the partition 110 cooperates with the upper guide rail surface 111 to form the first running track 101; part of the partition 110 cooperates with the lower guide rail surface 112 to form the second running track 102.

[0055] In this embodiment, the main difference from the above embodiment is that the first running track 101 can be located above the second running track 102, and the two are separated by a partition 110, thereby preventing interference between the synchronous belt 300.

[0056] Overall, the guide rail body 100 comprises an upper guide rail surface 111 and a lower guide rail surface 112 facing each other. A separator 110, bent at a predetermined angle, is disposed between the upper and lower guide rail surfaces 111 and 112. Specifically, as shown in FIG6 , the separator 110 comprises two bends. The upper first bend cooperates with the upper guide rail surface 111 to form the first running track 101, while the lower second bend cooperates with the lower guide rail surface 112 to form the second running track 102.

[0057] Specifically, the shape, structure, and bending angle of the first and second bends can be adaptively designed based on the structures of the upper guide surface 111, the lower guide surface 112, the synchronous belt 300, the slider 200, etc., so as to cooperate with the upper guide surface 111 and the lower guide surface 112 to form a running track that is compatible with the synchronous belt 300 and the slider 200. Of course, the specific shape and structure of the separator 110 are not limited to the above examples. Inspired by the technical essence of this application, those skilled in the art may make other changes. However, as long as the functions and effects achieved are the same or similar to those of the present application, they should be covered by the scope of protection of this application.

[0058] In this embodiment, in order to limit the synchronous belt 300 located in the second running track 102, the end of the lower guide surface 112 that cooperates to form the second running track 102 can be bent upward.

[0059] Please refer to FIG. 3 or FIG. 6 . In the embodiment of the present application, a first bending portion 1121 is provided on the lower guide rail surface 112 . Part of the lower guide rail surface 112 cooperates with the first bending portion 1121 to form the third running track 103 .

[0060] The first bending portion 1121 and part of the lower guide rail surface 112 can be arranged relative to each other to form a third running track 103 for installing the sunshade edge strip 602. The third running track 103 and the first running track 101 and the second running track 102 all extend along the longitudinal direction of the track body.

[0061] Please refer to FIG. 3 or FIG. 6 . In different embodiments, the limiting groove 104 is formed in different ways.

[0062] As shown in FIG6 , in one embodiment, for example, for the scenario of cloth being discharged from the top, when the partition 110 is a bent structure at a predetermined angle, the first bent portion 1121 cooperates with the partition 110 and the lower guide rail surface 112 to form the limiting groove 104 .

[0063] That is, for the upper cloth discharge scenario, the portion of the partition 110 near the lower guide rail surface 112 can be positioned opposite the first bent portion 1121. The first bent portion 1121 cooperates with a portion of the partition 110 and the lower guide rail surface 112 located therebetween to form a retaining groove 104. When the slider 200 is engaged with the retaining groove 104, the slider 200 is retained in the first direction Y.

[0064] As shown in Figure 3, in another embodiment, for example, for the scenario of cloth being discharged from the bottom, when the partition portion 110 is arranged on the connecting surface between the upper guide rail surface 111 and the lower guide rail surface 112, a limiting member 122 is also provided on the lower guide rail surface 112, and the limiting member 122 cooperates with the first bending portion 1121 and the lower guide rail surface 112 to form the limiting groove 104.

[0065] In other words, for the lower cloth discharge scenario, a stopper 122 is further provided on the lower guide rail surface 112. This stopper 122 can be specifically a baffle extending along the longitudinal extension of the guide rail body 100 and disposed opposite the first bent portion 1121. The first bent portion 1121, the stopper 122, and the lower guide rail surface 112 located therebetween cooperate to form a stopper slot 104. When the slider 200 engages with the stopper slot 104, the slider 200 is stopped in the first direction Y.

[0066] Please refer to Figure 8. In one embodiment, when the partition portion 110 is arranged on the connecting surface between the upper guide surface 111 and the lower guide surface 112, the end of the partition portion 110 away from the connecting surface cooperates with the first bending portion 1121 to form the limiting portion.

[0067] In this embodiment, the main difference from the embodiment shown in FIG4 is the specific form of the position-limiting portion. In this embodiment, the position-limiting portion is formed by utilizing the partition portion 110 and the first bending portion 1121 in combination.

[0068] Specifically, the first bent portion 1121 includes a first portion extending along the second direction Z and a second portion extending along the first direction Y. One end of the first portion is connected to the lower guide rail surface 112, and the other end is connected to the second portion. When the slider 200 is installed in the guide rail body 100, the end of the partition 110 can abut against the slider 200, and the first portion of the first bent portion 1121 can abut against the slider 200, thereby limiting the slider 200 in the first direction Y.

[0069] In some embodiments, the slider 200 has a boss extending into the third running track 103 , the boss is provided with a claw 201 , and the sunshade side strip 602 is provided with a side strip hole that cooperates with the claw 201 .

[0070] Specifically, the slider 200 has a boss extending into the third running track 103, and the claw 201 can be in the form of two hooks arranged on the lower surface of the boss. The side strip 602 can be mounted on the hook through the side strip hole. The above-mentioned matching structure can not only guide the side strip 602 into the guide rail, but also limit the side strip 602 to reduce the possibility of the side strip 602 falling out.

[0071] The claw 201 can be loosely matched with the track plane of the third running track 103. Specifically, the distance from the claw 201 to the track plane of the third running track 103 is 0.1 mm-1.5 mm, thereby ensuring that when the edge strip 602 is driven by the slider 200 to move, the claw 201 will not contact the guide rail body 100, causing wear and abnormal noise.

[0072] As shown in Figure 8, a pull rod 601 can be provided at one end of the curtain (not shown in Figure 8). The pull rod 601 can be fixed to the slider 200. When the sunshade needs to be opened or closed, the driving source drives the gear to move, the gear movement drives the synchronous belt 300 to move, and the synchronous belt 300 drives the slider 200 and the pull rod 601 to move, so that the side strip 602 that cooperates with the slider 200 moves, and when the pull rod 601 moves, it drives the curtain to move, thereby completing the opening and closing of the sunshade. Among them, the driving source can be a motor. Of course, the driving source is not limited to a motor, and can also be achieved manually.

[0073] As shown in FIG. 4 , in some embodiments, the sunshade guide rail further includes an elastic engaging member 500 , which is disposed between the guide rail body 100 and the slider 200 and is used to limit the slider 200 in the second direction Z.

[0074] In this embodiment, in order to limit the slider 200 in the second direction Z, an elastic engaging member 500 can be provided between the guide rail body 100 and the slider 200. Through the elastic engaging member 500, it can be ensured that the slider 200 is in an interference fit with the upper guide rail surface 111 and the lower guide rail surface 112. Specifically, the elastic engaging member 500 can be provided between the slider 200 and the upper guide rail surface 111. The elastic engaging member 500 can specifically be in the form of a metal spring with a certain curvature. Of course, the specific form of the elastic engaging member 500 is not limited to the above description. Inspired by the technical essence of this application, those skilled in the art may also make other changes. However, as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0075] Furthermore, the elastic engaging member 500 may be provided on the upper guide rail surface 111 , and the first bending portion 1121 cooperates with the elastic engaging member 500 to limit the slider 200 along the second direction Z.

[0076] Specifically, the first bent portion 1121 includes a first portion extending along the second direction Z and a second portion extending along the first direction Y, wherein one end of the first portion is connected to the lower guide rail surface 112, and the other end is connected to the second portion. Specifically, the second portion of the first bent portion 1121 can be used to cooperate with the elastic engaging member 500 to limit the position of the slider 200 in the second direction Z. Aside from the slider 200, there are no other assembly components between the first bent portion 1121 and the upper guide rail surface 111 provided with the elastic engaging member 500. Therefore, there are no assembly errors that could affect the mating accuracy, thereby enabling more reliable positioning of the slider 200.

[0077] In some embodiments, along the second direction Z, the guide rail body 100 has an upper guide rail surface 111 facing the slider 200 , and a second bending portion 113 with an opening facing downward and outward is formed at the end of the upper guide rail surface 111 .

[0078] In this embodiment, a second bending portion 113 can be provided on the upper guide rail surface 111. The second bending portion 113 can be used to form a glue injection gap between the glass and the guide rail body 100 on the one hand, and can also be used to provide a reference position for installation positioning for subsequent assembly on the other hand.

[0079] For example, a pre-fixing portion 401 is provided on the second bending portion 113. Specifically, the pre-fixing portion 401 can be in the form of a double-sided tape. Of course, the pre-fixing portion 401 can also be in other forms, and this application uses double-sided tape as an example for illustration.

[0080] When double-sided tape is provided on the second bending portion 113 , during subsequent glue injection, the double-sided tape forms a glue injection boundary, thereby preventing glue from overflowing during glue injection, or even overflowing onto the moving surface of the guide rail.

[0081] Along the second direction Z, the guide rail body 100 has an outer surface facing the glass, and an adhesive structure is provided between the outer surface and the glass. The adhesive structure includes a main layer 411 extending as a whole along the first direction Y and an extension portion 412 extending along the second direction Z.

[0082] Overall, the bonding structure is L-shaped. The L-shaped bonding structure can not only limit the movement of the guide rail along the first direction Y, but also protect the plastic guide rail.

[0083] Currently, the existing method of fixing the guide rail and the glass is usually to fix them by screws locked with embedded nuts. Due to the large number of bolts locked with the embedded nuts, a lot of time is consumed at the work station.

[0084] As shown in Figure 4, along the second direction Z, the downward projection of the elastic snap-fit ​​member 500 at least partially covers the first bending portion 1121, and the upward projection of the elastic snap-fit ​​member 500 at least covers the second bending portion 113, so that the elastic snap-fit ​​member 500 can be reliably pressed between the slider 200 and the guide rail body 100, while ensuring that the slider 200 is reliably limited in the second direction Z, and also ensuring that the entire guide rail structure is balanced in force, and there will be no problems such as local uneven force affecting the structural strength.

[0085] The sunshade rail provided in this application is molded in one piece. During assembly, the glass and rail are pre-assembled, and then PU edging is injected to directly fix them. The PU edging structure greatly improves assembly efficiency while ensuring the strength of the rail and glass assembly.

[0086] As shown in Figure 3, the PU edging structure may also be provided with a glue discharge port, the position of which corresponds to the position of the notch 403 in Figure 3. By using the glue discharge port in conjunction with the double-sided tape, the glue injection efficiency can be improved while ensuring that the glue is efficiently formed at the predetermined position during glue injection.

[0087] Based on the sunshade guide rail provided in the above embodiment, the present application further provides a sunshade guide rail assembly method, which may include:

[0088] Step S11: providing a pre-fixing portion 401 at a predetermined position on the sunshade guide rail to pre-assemble the glass and the sunshade guide rail;

[0089] Step S12: injecting adhesive into a predetermined assembly gap formed between the glass and the sunshade guide rail, wherein the adhesive can form a predetermined bonding structure.

[0090] When assembling and fixing the sunshade rail to the glass, the sunshade rail provided in this application can be pre-fixed by providing a pre-fixing portion 401 (e.g., double-sided tape) at a predetermined position (e.g., at the second bend 113), and then pouring an adhesive (e.g., PU glue) to complete the fixation of the rail to the glass. Compared with the existing method of fixing by screws and embedded nuts, the overall structure is simple and the assembly efficiency is high.

[0091] In addition, by providing a pre-fixing portion 401 (such as double-sided tape), it is possible to prevent the PU glue from overflowing onto the moving surface of the guide rail.

[0092] Adding a glue discharge port to the PU edge injection molding structure allows excess glue from the PU edge to flow out through the glue discharge port. The bonding structure is L-shaped, which not only limits the movement of the guide rail along the first direction Y, but also protects the plastic guide rail.

[0093] It should be noted that, in the description of this application, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0094] The above-mentioned various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
