Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to a guide rail assembly for sunshade transmission and a vehicle. Background Technology

[0002] Existing automotive electric sunshade guide rail structures generally adopt a multi-piece splicing structure. While this design seems to meet basic guiding functions, it has revealed many shortcomings in practical applications. The splicing characteristics of multi-piece guide rails require extremely high dimensional accuracy and fit tolerances between components; otherwise, problems such as splicing gaps and guide jamming can easily occur. This significantly increases the difficulty of mold development, component processing, and assembly calibration, not only increasing manufacturing costs but also reducing product yield. More importantly, the automotive environment imposes strict limitations on the installation space of components, especially in areas such as door interior panels and the edges of sunroofs. The reserved installation cavities are already small and compact, and the stacked structure of multi-piece guide rails further squeezes the limited space, making the assembly process of the sunshade body and guide rails extremely cumbersome. Operators often have to complete multiple sets of buckle fixing, screw tightening, or slot docking in a narrow operating space. This not only results in low assembly efficiency but also easily leads to guide rail deformation, sunshade fabric wrinkles, and even affects the smooth sliding function of the sunshade. Furthermore, to enhance aesthetics, many current sunshades are equipped with ambient lighting. The light sources used to illuminate the sunshades (such as LED strips and miniature LEDs) also require installation space. Multi-piece guide rails already occupy most of the available space, leaving very little room for the lighting components. Precisely matching the fixed position of the light source is difficult; forcibly embedding it may interfere with the guide rail's structure, affecting the normal operation of the sunshade and making installation quite challenging. Therefore, there is an urgent need for a guide rail assembly and vehicle for sunshade lighting to solve the aforementioned technical problems. Utility Model Content

A first retaining block is fixedly provided on the lower end face of the top edge of the U-shaped groove, and a first groove is provided on the upper part of the first leg. The first retaining block and the first groove can engage. A second retaining block is fixedly provided on the upper end face of the bottom edge of the U-shaped groove, and a second groove is provided on the second leg. The second retaining block and the second groove can engage.

[0009] In some embodiments, the end of the first leg away from the sunshade is connected to the end of the second leg away from the sunshade by an arc transition, and the angle between the first leg and the second leg in the initial state is 69 degrees to 71 degrees.

[0010] In some embodiments, a heat sink is also included, which is fixedly disposed on the upper end face of the second leg and located between the flexible circuit board and the second leg, with the flexible circuit board attached to the heat sink.

[0011] In some embodiments, a rectangular protrusion is fixedly provided on the upper end face of the first leg, and the side of the rectangular protrusion can fit against the end of the top edge of the U-shaped groove.

The guide rail is integrally molded, simplifying processing and installation, and making the installation of the sunshade curtain and LED strip faster and more convenient. The elastic clip, after bending, directly snaps into the cavity of the guide rail, resisting the inner wall of the cavity under the action of rebound force, eliminating the need for screws and other clips, significantly reducing installation time. Furthermore, the cavity integrates the light-emitting element, elastic clip, and the mounting part of the sunshade curtain, resulting in a high degree of integration and simplifying production and installation.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The purpose of this utility model is to provide a guide rail assembly and vehicle for conducting sunshade curtains, so as to solve the problems existing in the prior art, making the processing simpler and the installation more convenient.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figures 1-4 As shown, this utility model provides a guide rail assembly for a sunshade curtain, including a sunshade curtain 2, a guide rail 1, an elastic clip 3, and a light strip. The guide rail 1 is integrally formed and fixedly installed on the vehicle. The guide rail 1 has a cavity. The elastic clip 3 is bent into a U-shape and has a rebound force. The elastic clip 3 is engaged in the cavity and extends along the length of the guide rail 1. The sunshade curtain 2 is slidably disposed at the opening of the cavity. The sunshade curtain 2 has a light-emitting guide wire inside. The light strip is fixedly disposed on the elastic clip 3 and can illuminate the side wall of the sunshade curtain 2. The light strip is electrically connected to a power supply system. After the elastic clip 3 is bent into a U-shape, it is engaged in the cavity of the guide rail 1. The light strip is fixed on the elastic clip 3, and thus the light strip is fixed to the guide rail 1. The integral forming of the guide rail 1 is relatively simple to process and install, and the installation of the sunshade curtain 2 and the light strip is also faster and more convenient. After bending, the elastic clip 3 directly engages with the cavity of the guide rail 1, and under the action of rebound force, it abuts against the inner wall of the cavity, eliminating the need for screws and other clips, thus significantly reducing installation time. Furthermore, the installation parts for the light-emitting element, elastic clip 3, and light-blocking curtain are integrated within the cavity, resulting in a high degree of integration and simplifying production and installation.

[0022] It should be noted that the power supply system can use a battery to power the LED strip or a branch wire can be drawn from the power supply system of the sunshade roller to power the LED strip.

[0023] In some embodiments, the guide rail 1 assembly for the conduction of the sunshade curtain 2 further includes an abutment 7, a first wedge block 311, and a hook 16. The hook 16 is disposed at one end of the bottom edge 12 of the cavity near the sunshade curtain 2. The hook 16 extends along the length of the guide rail 1 and bends inward from the bottom edge 12 of the cavity toward the opening of the cavity. The upper leg of the elastic clip 3 has a first wedge block 311 disposed on the side facing away from the top edge 11 of the cavity. The inclined surface of the first wedge block 311 gradually moves away from the upper leg from the middle of the upper leg to the end near the sunshade curtain 2. The abutment 7 is fixedly connected to the sunshade curtain 2. The top of the abutment 7 is in contact with the inclined surface of the first wedge block 311, and the bottom of the abutment 7 is in contact with the inner side of the hook 16. The top of the abutment 7 is in contact with the first wedge block 311, and the bottom abuts against the hook 16, so that the abutment 7 can slide along the length of the guide rail 1.

[0024] In some embodiments, the guide rail 1 assembly for transmitting light through the sunshade curtain 2 further includes a light-blocking strip 6. The first end of the light-blocking strip 6 is fixedly connected to the upper support leg, preferably by adhesive. The second end of the light-blocking strip 6 is attached to the upper surface of the sunshade curtain. The sunshade curtain 2 is slidably disposed between the lower end face of the cavity and the light-blocking strip 6. After the sunshade curtain 2 leaves the space between the lower end face of the cavity and the light-blocking strip 6, the light-blocking strip 6 can be attached to the lower end face of the cavity. The light-blocking strip 6 and the lower end face of the cavity of the original guide rail 1 form a double-sided wrapping structure for the sunshade curtain 2. When the sunshade curtain 2 is located between the two, it can tightly seal the gap between the sunshade curtain 2 and the guide rail 1. When the sunshade curtain 2 leaves this area, the light-blocking strip 6 is attached to the lower end face of the cavity, which can also seal the opening of the guide rail 1, preventing external light from entering through the gaps in the guide rail 1 itself or the light from the light-emitting strip from emitting light. It should be noted that the light-blocking strip 6 can be made of soft materials such as sponge and have a certain degree of resilience, or the light-blocking strip 6 can be made of materials such as rubber.

[0025] In a preferred embodiment, the light-shielding strip 6 is hook-shaped. The second end of the light-shielding strip 6 bends inward from the upper support leg toward the opening of the elastic clip 3, ensuring a good sealing effect. It fits against the top surface of the hook 16, so that the light-shielding strip 6 and the cavity of the guide rail 1 form a sealed cavity, preventing light from escaping. It should be noted that the light-shielding strip 6 can also be set as a straight line with an inclined setting, as long as it can ensure that it can form a sealed cavity with the cavity of the guide rail 1 to prevent light from escaping.

[0026] In some embodiments, the light strip is an LED light strip, including a flexible circuit board 8 and multiple LED beads 4. The LED beads 4 are electrically connected to the flexible circuit board 8. The flexible circuit board 8 is fixedly disposed on the upper end surface of the lower leg of the elastic clip 3. The LED light strip is arranged along the length direction of the guide rail 1. The sunshade 2 is provided with light guiding material, and the pipeline can transmit along the path of the light guiding material. By setting the light guiding material, such as adding laser etching breakpoints, different light emission effects and different illumination shapes can be formed. The flexible circuit board 8 has a small thickness, small size, and light weight. It does not occupy too much extra space when fixed on the upper end surface of the lower leg of the elastic clip 3, nor does it affect the sliding of the sunshade 2 between the hook 16 and the light-blocking strip 6. At the same time, it is highly flexible and can flexibly adapt to the slight curvature of the guide rail 1. Even if the guide rail 1 has a slight processing curvature or slight deformation after installation, it can still fit tightly against the lower leg of the elastic clip 3 without additional shape adjustment, adapting to the installation requirements of guide rail 1 for different vehicle models.

[0027] In some embodiments, the cavity is a U-shaped groove, with the top edge 11 and bottom edge 12 of the U-shaped groove both horizontally arranged. The first leg 31 of the elastic clip 3 abuts against the top edge 11 of the U-shaped groove, and the second leg 32 of the elastic clip 3 abuts against the bottom edge 12 of the U-shaped groove. A first locking block 13 is fixedly arranged on the lower end face of the top edge 11 of the U-shaped groove, and a first groove 313 is arranged on the upper part of the first leg 31. The first locking block 13 and the first groove 313 can engage. After the first locking block 13 engages with the first groove 313, a secondary fixing structure with mechanical limiting is formed, which can limit the displacement of the elastic clip 3 in the vertical and horizontal directions and the front and back directions, effectively preventing the elastic clip 3 from falling out of the U-shaped groove or loosening, thereby ensuring the stability of the position of components such as the light strip and the spotlight strip 5, and improving the reliability of the overall structure. When installing the elastic clip 3, the first locking block 13 can form a precise positioning and guiding effect with the first groove 313. Operators do not need to repeatedly adjust the position of the elastic clip 33. They only need to align the groove with the clip and snap it in to quickly and accurately install the elastic clip 3. This reduces the calibration steps during installation, improves assembly efficiency, and avoids problems such as the sunshade 2 sliding and jamming or the light strip illuminating off-center due to misalignment.

[0028] In some embodiments, a second locking block 14 is fixedly provided on the upper end face of the bottom edge 12 of the U-shaped groove, and a second groove 322 is provided on the second support leg 32. The second locking block 14 and the second groove 322 can engage. Previously, although only the top engagement could limit some displacement, the severe bumps during vehicle movement could still cause the lower part of the elastic clip 3 to loosen. The engagement of the second locking block 14 and the second groove 322, together with the top engagement structure, forms a double-sided fixation, firmly limiting the elastic clip 3 in the U-shaped groove, restricting its vertical, horizontal, and lateral displacement in all directions. This further prevents the elastic clip 3 from falling out of the U-shaped groove, while ensuring that the positions of components such as the light strip fixed on the second support leg 32 and the focusing strip 5 on the first support leg 31 remain stable, greatly improving the overall reliability of the guide rail 1 structure. When installing the elastic clip 3, the upper and lower locking blocks and the groove can form a bidirectional positioning guide. Operators only need to align the upper and lower sets of snap-fit ​​structures and push them in to quickly and accurately install the elastic clip 3 without repeated adjustments and calibrations. This not only reduces assembly steps and improves loading efficiency, but also avoids problems such as the sunshade 2 sliding and jamming, and the relative position of the spotlight strip 5 and the light strip shifting due to misalignment, ensuring the coordinated working effect of each component of the guide rail 1 after assembly.

[0029] In some embodiments, the end of the first leg 31 away from the sunshade 2 and the end of the second leg 32 away from the sunshade 2 are connected by an arc transition, and the initial angle between the first leg 31 and the second leg 32 is 69-71 degrees, so that they can be inserted into the U-shaped groove after bending and pressing. The elastic clip 3 can be made of stainless steel sheet, shape memory alloy or other materials.

[0030] In some embodiments, the guide rail assembly for the sunshade curtain also includes a heat sink 9. The heat sink 9 is fixedly disposed on the upper end face of the second leg 32 and located between the flexible circuit board 8 and the second leg 32. The flexible circuit board 8 is attached to the heat sink 9, and the heat sink 9 is a metal strip. The thermal conductivity of metal itself is much higher than that of the polyimide substrate of the flexible circuit board 8. Common metal heat sinks such as aluminum and copper can quickly absorb the heat generated by the LED beads on the flexible circuit board 8 when they are working, and then evenly conduct the heat to the second leg 32, and then diffuse it to the entire guide rail assembly. This can avoid problems such as color temperature shift and brightness decay of the LED beads 4 due to local heat accumulation, and can also reduce the light decay rate of the LED strip caused by high temperature and extend its service life.

[0031] In some embodiments, a rectangular protrusion 312 is fixedly provided on the upper end face of the first leg 31. The side of the rectangular protrusion 312 can fit against the end of the top edge 11 of the U-shaped groove. A second wedge block 15 is fixedly provided on the bottom edge 12 of the U-shaped groove. The second wedge block 15 is located between the hook 16 and the second locking block 14, and the inclined surface of the second wedge block 15 gradually approaches the hook 16 from high to low. An inclined surface 321 is provided on the end of the second leg 32 near the hook 16. The inclined surface 321 gradually approaches the hook 16 from high to low and can fit against the inclined surface of the second wedge block 15. For the rectangular protrusion 312, its side fits against the end of the top edge 11 of the U-shaped groove, which can accurately limit the relative position of the first leg 31 and the U-shaped groove, avoiding the left and right offset or the up and down misalignment of the first leg 31 during assembly, and greatly reducing the assembly error of the first leg 31 and the U-shaped groove. Simultaneously, this structure can also assist in calibrating the overall straightness of the guide rail, preventing the sunshade 2 from sliding and jamming due to assembly deviations in the guide rail 1. The inclined surface of the second wedge block 15 and the inclined surface 321 of the second support leg 32 are designed to fit together, and their inclined angles match each other. During assembly, the installation position of the second support leg 32 and the bottom edge 12 of the U-shaped groove can be quickly and accurately located through the inclined surface guide, eliminating the need for complex positioning fixtures. This not only improves assembly efficiency but also ensures the consistency of each batch of guide rail 1 assembly. The fit between the rectangular protrusion 312 and the end of the top edge 11 of the U-shaped groove can distribute the force at the joint between the first support leg 31 and the U-shaped groove, avoiding stress concentration in the joint structure due to long-term vibration, and preventing deformation and loosening of the joint between the first locking block 13 and the first groove 313. The fit between the wedge block and the inclined surface 321 is an inclined locking structure. When subjected to the friction of the sliding of the sunshade 2 or external forces such as vehicle vibration, this structure will generate a mutual squeezing force, making the connection between the second support leg 32 and the bottom edge 12 of the U-shaped groove tighter. Moreover, the wedge structure can decompose longitudinal or lateral external forces, reduce the stress load on the second locking block 14 and the second groove 322, avoid wear at the locking point, and compensate for slight wear after long-term use, reduce structural shaking, and extend the service life of the guide rail 1.

[0032] In some embodiments, the sunshade curtain guide rail further includes a focusing strip 5. The light source is fixedly mounted on the second leg 32, and the focusing strip 5 is fixedly mounted on the first leg 31, with the focusing strip 5 located between the sunshade curtain 2 and the light source. The focusing strip 5 can concentrate the scattered light emitted by the light source, preventing the light from scattering in all directions and allowing most of the light to focus on the side wall of the sunshade curtain 2. This enhances the illuminance of the target area without increasing the power of the light source, ensuring clear visibility of the sunshade curtain 2's position while reducing energy consumption and making it more energy-efficient. The focusing strip 5 is fixed to the first leg 31, and the installation method is the same as that of the light-blocking strip 6, requiring no additional fixing structure design, making installation simpler.

[0033] In some embodiments, the abutment 7 is a binding strip. The curtain surface of the sunshade 2 near the end is attached to the plane of the upper part of the binding strip, and the lower end of the binding strip abuts against the inner end face of the hook 16. That is, the sunshade 2 is pasted on the binding strip, approximately at half the width of the binding strip, and can ensure that the side of the sunshade 2 is exposed without obstruction, so that the light strip can illuminate the side of the sunshade 2.

[0034] Example 2 This embodiment also provides a vehicle, including a sunshade 2 and a guide rail assembly for transmitting the sunshade as described in Embodiment 1. The installation of the guide rail 1, related lighting components, and sunshade 2 is relatively simple and efficient.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
