Description

Technical Field

[0001] This utility model relates to the technical field of sunroof edge strip guide design, and in particular to a sunroof with a floating guide. Background Technology

[0002] The side strip guide is fixedly installed on the end of the rear crossbeam of the car sunroof. By guiding the side strip into the guide rail, it ensures that the sunshade moves smoothly along the correct track during the opening and closing process, avoiding jamming, deviation or tangling, and ensuring smooth operation.

[0003] Currently, existing edge strip guide structures have the following technical problems: 1. Large space occupation: Existing fixed guides occupy a large space on the rear beam of the sunroof due to their complex structure; 2. Poor adaptability: Existing guides fixed to the rear beam of the sunroof sunshade provide a relatively singular guiding direction for the edge strip during use, and cannot be flexibly adjusted according to changes in the edge strip angle; 3. High edge strip friction: Due to the relatively singular operating angle of existing edge strip guides, when the edge strip controls the opening and closing of the sunshade, the changing edge strip angle generates significant contact friction with the guide, which can easily cause damage to the edge strip and the guide, or damage to the guide, the edge strip, the curtain, and the seams connecting the edge strip and the curtain. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a sunroof with a floating guide, which solves the problems of large space occupation, poor adaptability and large friction of the side strip guide in the prior art.

[0005] To achieve the above objectives, this utility model provides a skylight with a floating guide, comprising:

[0006] The sunroof assembly includes a front crossbeam and a rear crossbeam arranged in parallel; a side strip frame is fixedly provided on the side edge of the rear crossbeam, and a guide is movably installed between the rear crossbeam and the side strip frame;

[0007] The guide includes: a Z-axis limiting base plate, an X-axis contact rib, a connecting plate, and a support spring; the Z-axis limiting base plate is used to restrict the freedom of the edge strip in the Z-axis direction; at least one pair of X-axis contact ribs are symmetrically arranged on the Z-axis limiting base plate, and the X-axis contact ribs define a guiding area for the edge strip to pass through; at least one Y-axis limiting rib is provided on the outer side of one of the X-axis contact ribs, and a connecting plate is provided on the outer side of the other X-axis contact rib, with a protrusion provided below the connecting plate; one end of the support spring is fixedly connected to the rear crossbeam, and the other end of the support spring is detachably connected to the protrusion to provide elastic floating support for the guide;

[0008] The side strip frame includes a rotating mechanism mounted on the rear crossbeam. The rotating mechanism is used to roll up and release the side strip, which passes through the guide area and is driven to connect with the sunroof shade. The movement of the side strip controls the unfolding and retraction of the sunroof.

[0009] As a preferred approach, when the sunshade curtain is unfolded, the side strip and the curtain are driven to move along the positive Y-axis by the unfolding action of the sunshade, simultaneously pulling the guide upward relative to the rear crossbeam. As the height of the side strip dynamically changes during its movement, the guide adaptively adjusts its height through the elastic deformation of the support spring, ensuring that the side strip is always constrained within the guide zone defined by symmetrically arranged X-direction contact ribs, thus dynamically limiting the displacement of the side strip in the Y-axis direction. If the guide remains stationary while the side strip experiences height deviation due to changes in its movement trajectory, localized compression, friction, or collision may occur between the side strip and the guide (such as the X-direction contact ribs), leading to noise, wear, or even functional failure. The elastic buffering of the support spring allows the guide to float and compensate with the movement of the side strip, effectively avoiding hard impacts and localized stress concentrations, maintaining a more uniform and smooth contact between the side strip and the guide ribs, thereby reducing hard contact and frictional wear between the side strip and the guide, and helping to extend the service life of both the side strip and the guide.

[0010] As a preferred method, when the sunshade curtain is retracted, the side strip and the curtain are driven to move along the negative Y-axis by the retraction action of the sunshade, and simultaneously pull the guide to float downward relative to the rear crossbeam. As the height of the side strip changes dynamically during its movement, the guide adaptively adjusts its height through the elastic compression deformation of the support spring, ensuring that the side strip is always constrained within the guide zone defined by symmetrically arranged X-axis contact ribs, thus dynamically limiting the displacement of the side strip in the Y-axis direction. During the retraction process, due to factors such as mechanism linkage, material deformation, and installation tolerances, the actual movement trajectory of the side strip may not be a perfectly straight line, but rather accompanied by certain up-and-down fluctuations (i.e., changes in height). Through the elastic compression of the support spring, the guide can float downward synchronously with the side strip and curtain, and adjust its relative position in real time, thereby adaptively compensating for this dynamic change and avoiding jamming, friction, or guide failure caused by relative positional deviation between the fixed guide and the side strip. In addition, if the side strip guide is unstable when the sunshade is retracted, it can easily lead to uneven retraction of the curtain, local accumulation, or jamming. By dynamically limiting and adaptively guiding the displacement of the side strip in the Y-axis direction, it is ensured that the side strip always moves along the predetermined trajectory, thereby driving the sunshade to retract smoothly and evenly, improving the overall coordination and consistency of the movement.

[0011] As a preferred embodiment, the protrusion is cylindrical, with its central axis parallel to the central axis of the Y-direction limiting rib. This parallel alignment of the cylindrical protrusion and the Y-direction limiting rib facilitates a more compact and integrated design of the guide's overall structure. It allows for both elastic connection (via the protrusion) and precise positioning (via the Y-direction limiting rib) within a limited space, improving space utilization. During side-strip movement (especially when there are dynamic changes in the Y-axis direction), the guide is subjected to contact forces, frictional forces, and the reaction force of the supporting spring. If the protrusion (connecting spring) and the Y-direction limiting rib are spatially misaligned or their axes are not parallel, inconsistent force directions may occur, leading to localized stress concentration, structural distortion, or loose connections. When their central axes are parallel, a more coordinated force transmission path is formed, resulting in a better balance between the spring's elastic force, the side-strip's contact force, and the guide's supporting force. This reduces the risk of localized stress concentration and structural fatigue, improving durability and reliability.

[0012] As a more preferred approach, the Y-direction limiting rib is perpendicular to the upper surface of the Z-direction limiting base plate, and the extension direction of the Y-direction limiting rib is parallel to the Y-axis reference direction. When the Y-direction limiting rib is perpendicular to the upper surface of the Z-direction limiting base plate, its limiting surface (usually the side or edge) naturally forms a "stop edge" structure perpendicular to the base plate and parallel to the Y-axis. If the edge strip deviates in the Y direction during movement, it will contact this limiting surface and be guided and constrained. This "vertical + parallel" arrangement makes the contact between the limiting rib and the edge strip more stable and controllable, avoiding poor contact, uneven force, or guide failure caused by angular deviation. Furthermore, if the Y-direction limiting rib is perpendicular to the upper surface of the Z-direction limiting base plate, the manufacturing process can be simplified, eliminating the need for complex inclined surfaces or irregular structures, and reducing processing difficulty. In addition, its extension direction being parallel to the Y-axis reference direction also facilitates intuitive direction identification and precise positioning during installation or debugging, helping to reduce processing costs and improve production efficiency and product consistency.

[0013] As a more preferred approach, the connecting plate is perpendicular to the upper surface of the X-direction contact rib, and the normal direction of the connecting plate is parallel to the Y-axis reference direction. Since the normal direction of the connecting plate is parallel to the Y-axis reference direction, its "orientation" is consistent with the Y-axis direction, which is highly beneficial for arranging and connecting the support spring (or other elastic elements) along the Y-direction. Furthermore, the fact that the normal direction of the connecting plate is parallel to the Y-axis reference direction means that the connecting plate is functionally "oriented" towards the Y-axis direction, which highly matches its actual role in the guide system (such as connecting Y-direction related springs, transmitting Y-direction force, and assisting in guidance). This enhances the functional synergy between the connecting plate and other functional components of the guide (such as Y-direction limiting ribs and support springs), improving the overall system performance and reliability. Further, when the connecting plate is arranged perpendicular to the upper surface of the X-direction contact rib, and its normal direction is consistent with the Y-axis direction, the force transmission path of the entire guide in the Y-axis direction is clearer and more reasonable, helping to avoid off-center loading, torsion, or abnormal stress concentration caused by improper arrangement of the connecting parts. This structural design enables the guide to more stably bear and transmit forces during the movement of the side strips (especially when there are dynamic changes in the Y-axis direction), thereby improving overall durability and reliability.

[0014] As a preferred approach, the width of the guide area is greater than the width of the edge strip, and the inner walls of the guide area on both sides are evenly spaced with the outer edge of the edge strip. If the width of the guide area is equal to or too small than the width of the edge strip, the edge strip is prone to friction, compression, or even jamming with the inner wall of the X-direction contact rib during movement, especially when the edge strip has manufacturing tolerances, thermal expansion and contraction, or deformation under stress. Designing the width of the guide area to be greater than the width of the edge strip, with a reasonable gap, can effectively avoid direct hard contact or over-constraint between the edge strip and the guide rib, allowing the edge strip to slide or move smoothly within the guide area, reducing frictional resistance and abnormal wear, and helping to extend the service life of the edge strip. In addition, by making the inner walls of the guide area on both sides evenly spaced with the outer edge of the edge strip, it means that the edge strip is in a symmetrical, balanced, and central position within the guide area, without being biased to one side. This symmetrical gap design helps the edge strip always remain centered in the X-axis direction, preventing it from shifting left or right due to uneven force, assembly deviation, or dynamic movement. It ensures that the edge strip automatically tends to or remains in the center position when moving within the guide zone, improving guiding accuracy and movement consistency.

[0015] As a more preferred approach, the cross-section of the X-direction contact rib is trapezoidal, and the inner surface of the X-direction contact rib near the guide area is a guide slope. Because the inner surface of the X-direction contact rib is a slope (guide slope), rather than a vertical or steep straight surface, the edge strip can smoothly transition along the slope when moving into the guide area, avoiding jamming, jumping, or assembly difficulties due to sudden contact with a hard wall. This slope design is more user-friendly for the initial introduction, dynamic movement, and assembly process of the edge strip. Especially when the edge strip is slightly misaligned or not perfectly centered, it can naturally guide it back to the center position of the guide area, improving the smoothness of the edge strip entering the guide area, enhancing assembly error tolerance, and reducing jamming and poor introduction phenomena. In addition, the X-direction contact ribs of the trapezoidal cross section, together with the guide slope on its inner side, form a kind of "flexible limit" or "asymptotic constraint" for the edge strip, rather than a rigid boundary. That is, although the edge strip is restricted to a certain extent in the X-axis direction, it will not be "stuck" or "forced to a certain extreme position", but can move flexibly within a certain gap range. This design avoids stress concentration, deformation or damage to the edge strip caused by over-constraint, and improves the motion stability and structural safety of the system.

[0016] As a more preferred approach, a gap exists between the lower surface of the Z-axis limiting base plate and the upper surface of the rear crossbeam to allow the guide to float along the Z-axis. If the guide is completely fixed to the rear crossbeam (without a Z-axis floating gap), when the side strip shifts vertically due to uneven force or external interference during movement, it is prone to hard collision or compression with the Z-axis limiting base plate, resulting in noise, vibration, or abnormal wear. With a Z-axis floating gap, the slight Z-axis displacement of the side strip will not immediately lead to hard contact, but will be buffered within a certain range by springs or other elastic elements, or compensated by the natural displacement of the guide, thereby reducing impact and friction damage, lowering the risk of hard contact between the side strip and the guide, and reducing wear and loosening. In addition, the guide is provided with elastic support by a support spring (such as a spring set between the rear crossbeam and the guide protrusion), enabling it to float and adjust in the Z-axis direction. If there is no gap between the Z-direction limiting base plate and the rear crossbeam, the elastic effect of the support spring may be restricted or ineffective, and it will be unable to perform its buffering and adaptive adjustment functions. After setting a reasonable Z-direction floating gap, the guide can float up and down with the movement of the side strip under the action of the spring, forming a more stable and sensitive elastic floating system.

[0017] As described above, the sunroof with a floating guide of this utility model has the following beneficial effects: When the sunroof with a floating guide of this utility model is in use, the guide restricts the freedom of the side strip in the vertical direction (Z-axis) through the Z-direction limiting base plate, preventing it from jumping up and down; the symmetrically arranged X-direction contact ribs form a guiding zone, restricting the offset of the side strip in the horizontal direction (X-axis), ensuring that the side strip moves along the correct trajectory; one of the X-direction contact ribs has a Y-direction limiting rib on its outer side, which constrains the displacement of the side strip in the front-to-back depth direction (Y-axis); the multi-directional limiting structure works together to effectively prevent the side strip from swaying, shaking or deviating from the guiding trajectory during movement, improving the trajectory accuracy of the side strip movement and the system stability. The side strip is effectively constrained in the X / Y / Z axes, making the movement more precise, avoiding jamming, deviation or twisting, and improving the reliability of the sunshade operation.

[0018] The guide is elastically connected to the rear crossbeam via a support spring. One end of the support spring is fixed to the rear crossbeam, while the other end is detachably connected to a protrusion below the connecting plate. This design allows the guide to adaptively float within a certain range along the Z-axis when the side strip moves or is subjected to external disturbances (such as vehicle vibration or installation deviations), compensating for dynamic position changes in the side strip. The elastic floating mechanism avoids hard contact, jamming, or abnormal wear between the guide and the side strip due to over-constraint, improving the system's adaptability to complex operating conditions. The guide can dynamically adjust its position according to the side strip movement or external disturbances, reducing impact and stress concentration, and improving the overall structural durability.

[0019] The width of the guide zone is greater than the width of the edge strip, and the inner walls on both sides of the guide zone (i.e., the inner side of the X-direction contact rib) and the outer edge of the edge strip are evenly spaced. This design ensures that the edge strip is reasonably constrained within the guide zone while retaining adequate space for movement, avoiding hard friction or jamming. The cross-section of the X-direction contact rib is preferably trapezoidal, and its inner surface near the guide zone is a guide slope. The edge strip can be smoothly guided into the guide zone along the slope and move in the center, further reducing friction and wear, and extending the service life of the edge strip and the guide.

[0020] The various functional components of the guide (such as the Z-axis limiting base plate, X-axis contact ribs, Y-axis limiting ribs, connecting plate, support spring, and protrusions) are spatially compact, functionally defined, and coordinate with each other. The connecting plate and the upper surface of the X-axis contact rib are perpendicularly arranged, with their normal direction parallel to the Y-axis reference direction, facilitating precise installation and force transmission of the support spring along the Y-axis. Furthermore, a gap is maintained between the Z-axis limiting base plate and the rear crossbeam to further support the guide's Z-axis floating function, forming a superior elastic support system with the support spring. The rational structural layout of each component and the synergistic optimization of functional components enhance overall integration and reliability. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0033] like Figures 1 to 5 As shown, this utility model provides a skylight with a floating guide, comprising:

[0034] Sunroof assembly 1, the sunroof assembly 1 includes a front crossbeam 12 and a rear crossbeam 11 arranged in parallel; a side strip frame 3 is fixedly provided on the side edge of the rear crossbeam 11, and a guide 2 is movably installed between the rear crossbeam 11 and the side strip frame 3;

[0035] The guide 2 includes: a Z-axis limiting base plate 24, an X-axis contact rib 22, a connecting plate 23, and a support spring 25; the Z-axis limiting base plate 24 is used to restrict the freedom of the edge strip 32 in the Z-axis direction; at least one pair of X-axis contact ribs 22 are symmetrically arranged on the Z-axis limiting base plate 24, and the X-axis contact ribs 22 define a guiding area for the edge strip 32 to pass through; at least one Y-axis limiting rib 21 is provided on the outer side of one of the X-axis contact ribs 22, and a connecting plate 23 is provided on the outer side of the other X-axis contact rib 22, and a protrusion 231 is provided below the connecting plate 23; one end of the support spring 25 is fixedly connected to the rear crossbeam 11, and the other end of the support spring 25 is detachably connected to the protrusion 231 to provide elastic floating support for the guide 2;

[0036] The side strip frame 3 includes a rotating mechanism 31 mounted on the rear crossbeam 11. The rotating mechanism 31 is used to roll up and release the side strip 32. The side strip 32 passes through the guide area and is driven to connect with the sunshade curtain. The movement of the side strip 32 controls the unfolding and retraction of the sunshade curtain.

[0037] In some embodiments of this utility model, such as Figures 2 to 3 As shown, when the curtain of the sunshade is unfolded, the side strip 32 is driven by the unfolding action of the sunshade to move along the positive Y-axis, and simultaneously pulls the guide 2 to float upward relative to the rear crossbeam 11. As the height position of the side strip 32 changes dynamically during its movement, the guide 2 adaptively adjusts its own height through the elastic deformation of the support spring 25, so that the side strip 32 is always constrained within the guide area defined by the symmetrically arranged X-direction contact ribs 22, thereby dynamically limiting the displacement of the side strip 32 in the Y-axis direction. If the guide 2 is fixed, but the side strip 32 experiences a height shift due to changes in its movement trajectory, it may cause local compression, friction, or collision between the side strip 32 and the guide 2 (such as the X-direction contact ribs 22), which may lead to noise, wear, or even functional failure. The elastic buffer of the support spring 25 allows the guide 2 to float and compensate with the movement of the side strip 32, effectively avoiding hard impacts and local stress concentration, and maintaining a more uniform and smooth contact between the side strip 32 and the guide rib, thereby reducing hard contact and frictional wear between the side strip 32 and the guide 2, and helping to extend the service life of the side strip 32 and the guide 2.

[0038] In some embodiments of this utility model, such as Figures 2 to 3As shown, when the sunshade curtain is retracted, the side strip 32 is driven by the retraction action of the sunshade curtain to move along the negative Y-axis, and simultaneously pulls the guide 2 to float downward relative to the rear crossbeam 11. As the height position of the side strip 32 changes dynamically during its movement, the guide 2 adaptively adjusts its own height through the elastic compression deformation of the support spring 25, so that the side strip 32 is always constrained within the guide area defined by the symmetrically arranged X-direction contact ribs 22, thereby dynamically limiting the displacement of the side strip 32 in the Y-axis direction. During the retraction process, due to the linkage relationship of the mechanism, material deformation, installation tolerance, etc., the actual movement trajectory of the side strip 32 may not be a perfectly straight line, but may be accompanied by a certain amount of up and down fluctuation (i.e., change in height position). Guide 2, supported by the elastic compression of spring 25, can float synchronously with the downward movement of side strip 32 and adjust its relative position in real time. This adaptively compensates for such dynamic changes, preventing jamming, friction, or guide failure caused by relative positional deviation between the fixed guide 2 and side strip 32. Furthermore, if the side strip 32 is unstable when the sunshade is retracted, it can easily lead to uneven fabric retraction, localized accumulation, or jamming. Dynamic limiting and adaptive guidance of the side strip 32's Y-axis displacement ensures that the side strip 32 always moves along a predetermined trajectory, thereby driving the sunshade to retract smoothly and evenly, improving overall coordination and consistency.

[0039] In some embodiments of this utility model, such as Figures 4 to 5 As shown, the protrusion 231 is a columnar body, and its central axis is parallel to the central axis of the Y-direction limiting rib 21. The parallel alignment of the columnar protrusion 231 and the Y-direction limiting rib 21 facilitates a compact and integrated design of the overall structure of the guide 2, enabling both elastic connection (via the protrusion 231) and precise positioning (via the Y-direction limiting rib 21) within a limited space, thus improving space utilization. When the side strip 32 moves (especially when there is a dynamic change in the Y-axis direction), the guide 2 is subjected to contact force, friction force, and reaction force from the side strip 32 and the supporting spring 25. If the protrusion 231 (connecting spring) and the Y-direction limiting rib 21 are misaligned in space or their axes are not parallel, it may lead to inconsistent force directions, resulting in local stress concentration, structural distortion, or loose connection. When their central axes are parallel, it helps to form a more coordinated force transmission path, making the elastic force of the spring, the contact force of the edge strip 32, and the supporting force of the guide 2 body more balanced, reducing the risk of local stress concentration and structural fatigue, and improving durability and reliability.

[0040] In some embodiments of this utility model, such as Figure 5As shown, the Y-direction limiting rib 21 is perpendicular to the upper surface of the Z-direction limiting base plate 24, and the extension direction of the Y-direction limiting rib 21 is parallel to the Y-axis reference direction. When the Y-direction limiting rib 21 is perpendicular to the upper surface of the Z-direction limiting base plate 24, its limiting surface (usually the side or edge) naturally forms a "stop edge" structure perpendicular to the base plate and parallel to the Y-axis. If the edge strip 32 deviates in the Y direction during movement, it will contact this limiting surface and be guided and constrained. This "vertical + parallel" arrangement makes the contact between the limiting rib and the edge strip 32 more stable and controllable, avoiding poor contact, uneven force, or guide failure caused by angular deviation. Furthermore, if the Y-direction limiting rib 21 is perpendicular to the upper surface of the Z-direction limiting base plate 24, it can simplify the manufacturing process, eliminating the need for complex inclined surfaces or irregular structures, and reducing processing difficulty. In addition, its extension direction is parallel to the Y-axis reference direction, which facilitates intuitive direction identification and precise positioning during installation or debugging, helping to reduce processing costs and improve production efficiency and product consistency.

[0041] In some embodiments of this utility model, such as Figure 5 As shown, the connecting plate 23 is perpendicular to the upper surface of the X-direction contact rib 22, and the normal direction of the connecting plate 23 is parallel to the Y-axis reference direction. Since the normal direction of the connecting plate 23 is parallel to the Y-axis reference direction, its "orientation" is consistent with the Y-axis direction. This is highly advantageous for arranging and connecting the support spring 25 (or other elastic elements) along the Y-axis. For example, if the support spring 25 is connected via the protrusion 231 below the connecting plate 23, this "normal parallel to the Y-axis" design ensures that the direction of the spring's elastic force matches the direction of movement or force on the edge strip 32 in the Y-axis direction, improving the guiding and floating control effect. This facilitates the directional installation of elastic elements such as the support spring 25, ensuring accurate transmission of its elastic force along the Y-axis direction and improving the guide 2's adaptive adjustment capability and stability of the edge strip 32's displacement in the Y-axis direction. Furthermore, the normal direction of the connecting plate 23 is parallel to the Y-axis reference direction, meaning that the connecting plate 23 is functionally "oriented" towards the Y-axis direction. This aligns perfectly with its actual function in the guide 2 system (such as connecting Y-axis related springs, transmitting Y-axis force, and assisting in guidance), enhancing the functional synergy between the connecting plate 23 and other functional components of the guide 2 (such as the Y-axis limiting rib 21 and support spring 25), thereby improving the overall system performance and reliability. Further, when the connecting plate 23 is arranged perpendicular to the upper surface of the X-axis contact rib 22, and its normal direction is consistent with the Y-axis direction, the force transmission path of the entire guide 2 in the Y-axis direction is clearer and more reasonable, helping to avoid off-center loading, torsion, or abnormal stress concentration caused by improper arrangement of the connecting plate 23. This structural design allows the guide 2 to more stably bear and transmit forces during the movement of the side strip 32 (especially when there are dynamic changes in the Y-axis direction), improving overall durability and reliability.

[0042] In some embodiments of this utility model, such as Figure 3 As shown, the width of the guide area is greater than the width of the edge strip 32, and the inner walls of both sides of the guide area are evenly spaced with the outer edge of the edge strip 32. If the width of the guide area is equal to or too small as the width of the edge strip 32, the edge strip 32 is prone to friction, compression, or even jamming with the inner wall of the X-direction contact rib 22 during movement, especially when the edge strip 32 has manufacturing tolerances, thermal expansion and contraction, or deformation under stress. Designing the width of the guide area to be greater than the width of the edge strip 32, with a reasonable gap, can effectively avoid direct hard contact or over-constraint between the edge strip 32 and the guide rib, allowing the edge strip 32 to slide or move smoothly within the guide area, reducing frictional resistance and abnormal wear, and helping to extend the service life of the edge strip. In addition, by making the inner walls of both sides of the guide area evenly spaced with the outer edge of the edge strip 32, it means that the edge strip 32 is in a symmetrical, balanced, and central position within the guide area, without being biased to one side. This symmetrical gap design helps the edge strip 32 to always remain centered in the X-axis direction, preventing it from shifting left or right due to uneven force, assembly deviation, or dynamic movement. This ensures that the edge strip 32 automatically tends to or remains in the center position when moving within the guide area, improving guiding accuracy and movement consistency.

[0043] In some embodiments of this utility model, such as Figures 3 to 5 As shown, the cross-section of the X-direction contact rib 22 is trapezoidal, and the inner surface of the X-direction contact rib 22 near the guide area is a guide slope. Because the inner surface of the X-direction contact rib 22 is a slope (guide slope), rather than a vertical or steep straight surface, the edge strip 32 can smoothly transition along the slope when moving into the guide area, without causing jamming, jumping, or assembly difficulties due to sudden contact with a hard wall. This slope design is more user-friendly for the initial introduction, dynamic movement, and assembly process of the edge strip 32. Especially when the edge strip 32 is slightly misaligned or its installation position is not completely centered, it can naturally guide it back to the center position of the guide area, improving the smoothness of the edge strip 32 entering the guide area, enhancing assembly error tolerance, and reducing jamming and poor introduction phenomena. In addition, the X-direction contact rib 22 of the trapezoidal cross section, together with the guide slope on its inner side, forms a kind of "flexible limit" or "asymptotic constraint" for the edge strip 32, rather than a rigid boundary. That is, although the edge strip 32 is restricted to a certain extent in the X-axis direction, it will not be "stuck" or "forced to a certain extreme position", but can move flexibly within a certain gap range. This design avoids stress concentration, deformation or damage to the edge strip 32 caused by over-constraint, and improves the motion stability and structural safety of the system.

[0044] In some embodiments of this utility model, such as Figures 3 to 5As shown, there is a gap between the lower surface of the Z-axis limiting base plate 24 and the upper surface of the rear crossbeam 11 to allow the guide 2 to float along the Z-axis. If the guide 2 is completely fixed to the rear crossbeam 11 (without the Z-axis floating gap), when the side strip 32 shifts vertically due to uneven force or external interference during movement, it is prone to hard collision or compression with the Z-axis limiting base plate 24, resulting in noise, vibration, or abnormal wear. With the Z-axis floating gap, the small Z-axis displacement of the side strip 32 will not immediately lead to hard contact, but will be buffered by springs or other elastic elements within a certain range, or compensated by the natural displacement of the guide 2, thereby reducing impact and friction damage, reducing the risk of hard contact between the side strip 32 and the guide 2, and reducing wear and loosening. In addition, the guide 2 is provided with elastic support by a support spring 25 (such as a spring set between the rear crossbeam 11 and the guide 2 protrusion 231), enabling it to float and adjust in the Z-axis direction. If there is no gap between the Z-direction limiting base plate 24 and the rear crossbeam 11, the elastic effect of the support spring 25 may be restricted or ineffective, and it will be unable to perform its buffering and adaptive adjustment functions. After setting a reasonable Z-direction floating gap, the guide 2 can float up and down with the side strip 32 under the action of the spring, forming a more stable and sensitive elastic floating system.

[0045] As described above, the sunroof with a floating guide of this utility model has the following beneficial effects: When the sunroof with a floating guide of this utility model is in use, the guide 2 restricts the freedom of the side strip 32 in the vertical direction (Z-axis) through the Z-direction limiting base plate 24, preventing it from jumping up and down; the symmetrically arranged X-direction contact ribs 22 form a guiding area, restricting the offset of the side strip 32 in the horizontal direction (X-axis), ensuring that the side strip 32 moves along the correct trajectory; one of the X-direction contact ribs 22 has a Y-direction limiting rib 21 on its outer side, which constrains the displacement of the side strip 32 in the front-to-back depth direction (Y-axis); the multi-directional limiting structure works together to effectively prevent the side strip 32 from swaying, shaking or deviating from the guiding trajectory during movement, improving the trajectory accuracy of the side strip 32 and the stability of the system. The side strip 32 is effectively constrained in the X / Y / Z axes, making the movement more precise, avoiding jamming, deviation or twisting, and improving the reliability of the sunshade operation.

[0046] The guide 2 is elastically connected to the rear crossbeam 11 via a support spring 25. One end of the support spring 25 is fixed to the rear crossbeam 11, and the other end is detachably connected to the protrusion 231 below the connecting plate 23. This design allows the guide 2 to adaptively float within a certain range along the Z-axis when the side strip 32 moves or is subjected to external disturbances (such as vehicle vibration, installation deviation, etc.), compensating for the dynamic position changes of the side strip 32. The elastic floating mechanism avoids hard contact, jamming, or abnormal wear between the guide 2 and the side strip 32 due to over-constraint, improving the system's adaptability to complex working conditions. The guide 2 can dynamically adjust its position according to the movement of the side strip 32 or external disturbances, reducing impact and stress concentration, and improving the overall structural durability.

[0047] The width of the guide area is greater than the width of the side strip 32, and the inner walls on both sides of the guide area (i.e., the inner side of the X-direction contact rib 22) and the outer edge of the side strip 32 are evenly spaced. This design ensures that the side strip 32 is reasonably constrained within the guide area while retaining adequate space for movement, avoiding hard friction or jamming. The cross-section of the X-direction contact rib 22 is preferably trapezoidal, and its inner surface near the guide area is a guide slope. The side strip 32 can be smoothly guided into the guide area along the slope and move in the center, further reducing friction and wear, and extending the service life of the side strip 32 and the guide 2.

[0048] The functional components of the guide 2 (such as the Z-direction limiting base plate 24, X-direction contact rib 22, Y-direction limiting rib 21, connecting plate 23, support spring 25, and protrusion 231) are spatially compact, functionally defined, and coordinate with each other. The upper surfaces of the connecting plate 23 and the X-direction contact rib 22 are perpendicularly arranged, with the normal direction of the plate surface parallel to the Y-axis reference direction, facilitating the precise installation and force transmission of the support spring 25 along the Y direction. In addition, a gap is maintained between the Z-direction limiting base plate 24 and the rear crossbeam 11 to further support the Z-direction floating function of the guide 2, forming a better elastic support system with the support spring 25. The structural layout of each component is reasonable, and the functional components are optimized in synergy, improving the overall integration and reliability.

[0049] In summary, the sunroof with a floating guide of this utility model has the following advantages:

[0050] 1. Precise multi-directional positioning improves the motion accuracy of the edge strip and the stability of the system.

[0051] The Z-direction limiting base plate 24, the symmetrical X-direction contact ribs 22, and the Y-direction limiting ribs 21 form a multi-directional limiting structure, which precisely constrains the movement of the edge strip 32 in the X / Y / Z three-axis directions; effectively preventing the edge strip 32 from swaying, shaking, deviating from the track, or twisting and deforming during the movement, improving the trajectory accuracy of the edge strip 32 and the overall stability of the system, and ensuring the reliable operation of the sunshade curtain.

[0052] 2. Enhance dynamic adaptability and anti-interference capability

[0053] The guide 2 is elastically connected to the rear crossbeam 11 through the support spring 25, allowing the guide 2 to adaptively float within a certain range along the Z-axis direction; it can effectively compensate for the positional changes of the side strip 32 and the system when moving or subjected to external disturbances (such as vibration, installation deviation, etc.), avoid hard contact, jamming and abnormal wear, and improve the system's adaptability and durability to complex working conditions.

[0054] 3. Improves smoothness and wear resistance during movement.

[0055] The width of the guide area is greater than the width of the side strip 32. The inner wall and the side strip 32 are distributed with equal gaps to avoid hard friction and jamming. The X-direction contact rib 22 adopts a trapezoidal cross section and the inner side is a guide slope to guide the side strip 32 to smoothly enter the guide area and move in the center, further reducing friction and wear, extending the service life of the side strip 32 and the guide 2, and improving the smoothness of movement.

[0056] 4. Reduce wear and noise, improve user comfort and product lifespan.

[0057] By reducing hard contact, friction, and jamming between the side strip 32 and the guide 2, wear, vibration, and noise during operation are reduced, improving the smoothness, consistency, and quietness of the sunshade's opening and closing actions, thus enhancing the user experience and product durability.

[0058] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
