TECHNICAL FIELD
[0001] The utility model relates to the field of automobile parts, concretely relates to a light guide strip mounting structure. BACKGROUND
[0002] The light guide strip is an optical component used in a lamp, which is usually a long strip-shaped article made of transparent or translucent material, has multiple surfaces inside, and can transmit light along its length direction. In the interior decoration of an automobile, the light guide strip is usually used to illuminate and decorate the interior of the automobile.
[0003] A light guide illumination device is disclosed in the utility model patent with the publication number "CN209054511U", which comprises a light guide strip, a soft light sheet and a reflecting piece. The light guide strip is composed of an integration section, a transition section and an outlight section connected in sequence. The outlight section comprises corresponding upper and lower end faces. The upper end face is an outlight face, and the lower end face is a light guide face. The light guide face is formed by a plurality of sawtooth structures arranged in parallel. The light guide strip is fixed on the reflecting piece. The reflecting piece has a reflecting face arranged below the light guide face. The soft light sheet is arranged above the reflecting piece and fixed on the reflecting piece. The soft light sheet has a light-transmitting face arranged above the outlight face.
[0004] However, the above-mentioned light guide illumination device has the following defects:
[0005] Firstly, the installation of the light guide strip is complicated. The soft light sheet and the reflecting piece need to be clamped on both sides of the light guide strip to realize the installation and fixation of the light guide strip. Meanwhile, the soft light sheet and the reflecting piece are easily separated during the driving process of the vehicle, causing the light guide strip to fall off.
[0006] Secondly, when the light guide strip is in the soft light sheet and the reflecting piece, the light guide strip is cylindrical as a whole. Under the action of vibration or external force during the driving process of the vehicle, the light guide strip is easily slided in the soft light sheet and the reflecting piece, causing the outlight width of the light guide strip to change, resulting in uneven outlight and affecting the illumination effect and visual experience.
[0007] Therefore, it is necessary to improve the above-mentioned defects. UTILITY MODEL CONTENT
[0008] The utility model aims to provide a light guide strip mounting structure with convenient light guide strip installation and stable light guide strip to solve the above-mentioned problems existing in the prior art.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a light guide strip installation structure, including an installation plate and a light guide strip. The installation plate is divided into a light guide part and a fastening part. The light guide part is provided with a plurality of spaced installation grooves. One end of the installation groove is provided with a fixing plate for fixing the light guide strip, and the other end is provided with a limiting plate for restricting the movement of the light guide strip. The end faces of both ends of the installation groove are provided with through holes for installing the light guide strip. One end of the light guide strip passes through the fixing plate, and the other end is provided with a limiting block that is linked with the limiting plate.
[0010] By adopting the above technical solution, the light guide strip is inserted into the mounting groove, with one end placed in the fixing plate and the other end placed in the limiting plate. This allows the light guide strip to be quickly positioned and inserted, achieving one end fixed and the other end limited. This avoids the light guide strip from repeatedly adjusting its position in the mounting groove, while also effectively limiting the light guide strip to prevent it from shaking or shifting. This ensures the alignment accuracy of the light guide strip within the structure, reduces light loss, and improves uniformity and light guiding efficiency.
[0011] The above-mentioned light guide strip installation structure can be further configured as follows: the light guide strip is divided into a light-emitting part, a connecting part and a fixing part, the connecting part is inserted into the fixing plate, the light-emitting part is provided with reflective serrations on one side of the mounting groove, and the limiting block is provided at the end of the fixing part and abuts against the limiting plate.
[0012] By adopting the above technical solution, the light guide strip is divided into a light-emitting section, a connecting section, and a fixing section, achieving synergistic optimization of light efficiency uniformity, structural stability, and ease of installation. The reflective serrations enhance the light scattering effect of the light guide strip, while the cooperation between the limiting block and the limiting plate effectively resists vibration and impact, facilitating maintenance and replacement, and resulting in a compact overall structure.
[0013] The above-mentioned light guide strip installation structure can be further configured as follows: the side of the limiting plate is provided with an abutment plate, the connection between the abutment plate and the limiting plate forms a limiting cavity, the limiting block is provided in the limiting cavity, the connection between the light guide strip and the limiting block is provided with a connecting plate, and the limiting plate is located at both ends of the connecting plate.
[0014] By adopting the above technical solution: the limiting cavity can stably constrain the limiting block, and together with the double-end limiting of the light guide strip connecting plate, a stable connection of the light guide strip is achieved. At the same time, it can accurately install the light guide strip to ensure optical alignment. The wrap-around limiting cavity significantly improves vibration resistance, and the plug-in structure makes assembly more convenient and supports rapid maintenance. It can maintain high stability and consistent light efficiency even in harsh environments.
[0015] The above-mentioned light guide strip mounting structure can be further configured as follows: the mounting plate has a mounting part on the light guide section, and a mounting hole is opened in the middle of the mounting part.
[0016] By adopting the above technical solution, the mounting holes facilitate the use of bolts, rivets and other fasteners to fix the mounting plate in the corresponding position, thereby achieving a stable installation of the mounting plate. In addition, the mounting part is located in the light guide part, so that the light guide strip can maintain a reasonable relative position with the light source and other components after installation, which is beneficial to the transmission and distribution of light.
[0017] The above-mentioned light guide strip installation structure can be further configured as follows: the inner wall of the through hole is provided with a number of spaced gaskets, and the mounting groove is provided with a number of snap-fit protrusions that fit against the circumference of the light guide strip.
[0018] By adopting the above technical solution, spacer pads are installed on the inner wall of the through hole, and snap-fit protrusions are added in the mounting groove. This achieves multiple supports for the light guide strip in the mounting groove, effectively buffering the contact stress between the light guide strip and the hole wall, preventing friction damage and reducing vibration transmission. At the same time, the snap-fit protrusions fit tightly against the circumference of the light guide strip, which not only enhances the fixing stability but also avoids local stress concentration, significantly improving the shock resistance and durability of the light guide strip while maintaining ease of installation.
[0019] The above-mentioned light guide strip installation structure can be further configured as follows: a first light guide inclined surface and a second light guide inclined surface are provided at the connection between the light guide part and the mounting groove, the first light guide inclined surface and the second light guide inclined surface are at an angle, a fixing post is provided on the end face of the mounting plate away from the mounting groove, a reinforcing rib is provided around the fixing post, and a guide rod is also provided at the edge of the fixing post.
[0020] By adopting the above technical solution, a first and second light-guiding inclined surface with an oblique angle are set at the connection between the light guide and the mounting groove, which can improve the light refraction path, enhance the uniformity of light output and the light efficiency utilization. The structural design of the fixed column with the peripheral reinforcing ribs greatly enhances the rigidity of the installation node and prevents deformation during long-term use. In addition, the guide rod ensures quick and accurate positioning during assembly, reduces installation errors, and further improves structural stability and assembly convenience while ensuring high light efficiency.
[0021] The above-mentioned light guide strip installation structure can be further configured such that: the fastening part has a fastening hole, and the end face of the fastening part has a number of fastening blocks.
[0022] By adopting the above technical solution, the fastening holes cooperate with the external fasteners to achieve positioning, ensuring the overall stability of the mounting plate, effectively dispersing stress and suppressing the risk of loosening caused by vibration, while retaining the convenience of disassembly, and significantly improving the mounting plate's resistance to displacement under dynamic loads.
[0023] The above-mentioned light guide strip installation structure can be further configured as follows: the bottom of the fastening part is provided with a first limiting protrusion and a second limiting protrusion, and a snap-fit hole is provided at the connection between the second limiting protrusion and the first limiting protrusion.
[0024] By adopting the above technical solution: the first limiting protrusion provides a primary positioning reference, the second limiting protrusion forms a height difference compensation to ensure a tight fit with the docking component, and the embedded cooperation between the snap-fit hole and the external buckle realizes mechanical self-locking, eliminating the risk of loosening of traditional screw fixing.
[0025] The beneficial effects of this utility model are as follows:
[0026] First, the mounting plate is equipped with a mounting groove and a fixing plate and a limiting plate are respectively set on both sides of the mounting groove to effectively limit the light guide strip. The through hole allows the light-emitting part of the light guide strip to be placed in the mounting groove and the connecting part to be placed in the fixing plate. The fixing part is linked with the limiting plate through the limiting block, which improves the convenience and stability of the light guide strip installation.
[0027] Secondly, spacer pads are installed on the inner wall of the through hole, and snap-fit protrusions are added in the mounting groove. This provides multiple supports for the light guide strip, effectively buffering the contact stress between the light guide strip and the hole wall, preventing friction damage and reducing vibration transmission. At the same time, the snap-fit protrusions fit tightly against the circumference of the light guide strip, which not only enhances the fixing stability but also avoids local stress concentration, significantly improving the shock resistance and durability of the light guide strip while maintaining ease of installation.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] like Figures 1 to 6 The light guide strip installation structure shown includes an installation plate 1 and a light guide strip 2. The installation plate 1 is divided into a light guide part 11 and a fastening part 12. The light guide part 11 is provided with a plurality of spaced installation grooves 13. One end of the installation groove 13 is provided with a fixing plate 14 for fixing the light guide strip 2, and the other end is provided with a limiting plate 15 for restricting the movement of the light guide strip 2. The end faces of both ends of the installation groove 13 are provided with through holes 16 for installing the light guide strip 2. One end of the light guide strip 2 passes through the fixing plate 14, and the other end is provided with a limiting block 21 that is linked with the limiting plate 15. The light guide strip 2 is inserted into the mounting groove 13, with one end placed in the fixing plate 14 and the other end placed in the limiting plate 15. This allows the light guide strip 2 to be quickly positioned and inserted, achieving one end fixed and the other end limited. This avoids the light guide strip 2 from repeatedly adjusting its position in the mounting groove 13, while also effectively limiting the light guide strip 2 to prevent it from shaking or shifting. This ensures the alignment accuracy of the light guide strip 2 within the structure, reduces light loss, and improves uniformity and light guiding efficiency.
[0038] The light guide strip 2 is divided into a light-emitting section 22, a connecting section 23, and a fixing section 24. The connecting section 23 passes through the fixing plate 14. The light-emitting section 22 has reflective serrations 221 on one side of the mounting groove 13. The limiting block 21 is located at the end of the fixing section 24 and abuts against the limiting plate 15.

The reflective serrations 221 enhance the light scattering effect of the light guide strip 2, and the mutual cooperation between the limiting block 21 and the limiting plate 15 effectively resists vibration and impact, while also facilitating maintenance and replacement. The overall structure is compact.
[0039] The limiting plate 15 has an abutment plate 151 on its side, and the connection between the abutment plate 151 and the limiting plate 15 forms a limiting cavity 152.

At the same time, the snap-fit protrusions 131 fit tightly against the circumference of the light guide strip 2, which enhances the fixing stability and avoids local stress concentration, significantly improving the shock resistance and durability of the light guide strip 2, while maintaining ease of installation.
[0042] The connection between the light guide section 11 and the mounting groove 13 is provided with a first light guide slope 111 and a second light guide slope 112. The first light guide slope 111 and the second light guide slope 112 are at an angle. A fixing post 17 is provided on the end face of the mounting plate 1 away from the mounting groove 13. The fixing post 17 is provided with reinforcing ribs 171 around its periphery, and a guide rod 172 is also provided at the edge of the fixing post 17. The first light guide slope 111 and the second light guide slope 112 with an angled fit at the connection between the light guide section 11 and the mounting groove 13 can improve the light refraction path, improve the uniformity of light output and the light efficiency utilization. The structural design of the fixing post 17 and the peripheral reinforcing ribs 171 greatly enhances the rigidity of the mounting node and prevents deformation during long-term use. In addition, the guide rod 172 ensures quick and accurate positioning during assembly, reduces installation errors, and further improves structural stability and assembly convenience while ensuring high light efficiency.
[0043] The fastening part 12 has a fastening hole 121, and a plurality of fastening blocks 122 are provided on the end face of the fastening part 12. The fastening hole 121 cooperates with the external fastener to achieve positioning, ensuring the overall fixed reliability of the mounting plate 1, effectively dispersing stress and suppressing the risk of loosening caused by vibration, while retaining the convenience of disassembly, and significantly improving the anti-displacement ability of the mounting plate 1 under dynamic load.
[0044] The bottom of the fastening part 12 is provided with a first limiting protrusion 123 and a second limiting protrusion 124. A snap-fit hole 125 is provided at the connection between the second limiting protrusion 124 and the first limiting protrusion 123.
