Abstract
Description
Technical Field
[0001] This invention is a flexible splicing grille light that adapts to curved guide rails, belonging to the field of household lighting technology. Background Technology
[0002] Existing grille lights, when used with guide rails, suffer from a fundamental drawback: poor compatibility with curved guide rails. This stems from the fact that traditional grille light holders are mostly rigid, integrated, or rigidly spliced designs, lacking flexible connecting structures. They can only fit straight guide rails. When faced with curved guide rail installation requirements, the rigid holders cannot adaptively adjust their angle or position to accommodate the curvature of the rail. Forced installation leads to insufficient fit between the holder and the rail, misalignment, and the lack of flexible compensation structures for the wiring between the holders makes them susceptible to stretching and bending, causing loosening or even breakage at connection points. Conventional solutions to this problem include manually bending the holder bracket, adding shims to fill the gap between the holder and the rail to force a fit, or replacing the light with a custom-designed curved grille light. The former involves physical modification to rigidly adapt to the curved structure, while the latter involves directly replacing the product with a compatible one. However, these methods have obvious drawbacks. Manually bending the bracket can easily cause deformation of the lamp holder structure and failure of the seal. The filling of the gasket will destroy the overall installation regularity. Both of these will significantly reduce the installation efficiency and increase the difficulty of manual operation. Therefore, there is an urgent need for a flexible splicing grille light that is compatible with curved guide rails to solve the above problems. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a flexible splicing grid light that adapts to curved guide rails, comprising: an outer guide rail, a lamp holder, a lamp body, and an interface, in order to solve the problems mentioned in the background art.
[0004] The technical solution of the present invention is implemented as follows: A flexible splicing grid light adapted to an arc-shaped guide rail includes: an outer guide rail, a lamp holder, a lamp body, and an interface. The upper end of the outer guide rail is provided with several sets of lamp holders for mounting the lamp bodies. Each set of lamp holders contains a set of lamp bodies for providing illumination. The bottom outer side of each set of lamp bodies is provided with a set of reflectors for expanding the light diffusion area. The reflectors are configured with a concave trapezoidal structure. The outer guide rail is an arc structure. The upper left and right sides of the outer guide rail are respectively provided with a set of interfaces for positioning and fitting with the lamp holders on the left and right sides. Several sets of inner wire holes for wiring of a single lamp holder are evenly distributed on the inner side between the two sets of interfaces. The lamp holder includes a sealing shell 1, a lamp cavity, and an inner groove. A set of sealing shell 2 is provided on the right side of the sealing shell 1. The sealing shell 1 is used for the leftmost lamp holder of the outer guide rail. The left side of the sealing shell 1 is a closed structure. Both the sealing shell 1 and the sealing shell 2 are provided with a set of lamp cavities for installing the flexible power take-off head of the lamp body. The upper end of the sealing shell 1 and the sealing shell 2 is provided with a set of sealing covers for keeping the inside of the lamp cavity sealed. The left side of the sealing shell 2 is a hollow structure. Inside the left side of the sealing shell 2 is a set of inner grooves for movable limiting engagement with the right side of the sealing shell 1. The bottom center of the inner side of the inner groove is provided with a set of limiting movable pins for positioning and connecting with the sealing shell 1.
[0005] In a preferred embodiment, the limiting pin is a cylindrical structure with an internal limiting groove for maintaining the pin's positioning and rotation. A support frame is located at the middle right side of the first sealing shell to improve the connection and support effect with the outer limiting seat. The support frame and the first sealing shell are integral. An outer limiting seat is located on the right side of the support frame for positioning and movably engaging with the limiting pin. The outer limiting seat has an external movable groove for engaging with the limiting pin. Inside the external movable groove is an internal positioning post for locking the position of the limiting pin. The internal positioning post passes through the internal limiting groove and maintains the movably engaged connection between the first and second sealing shells. This design improves installation compatibility based on the arc angle of the outer guide rail. First, open the sealing cover of the lamp holder and place the lamp body... The flexible power take-up head is accurately embedded into the lamp cavity, and the sealing cover is closed to keep the lamp cavity sealed. Then, according to the arc angle of the outer guide rail, the outer limit seat on the right side of the sealing shell one is aligned with the inner groove of the sealing shell two. The flexible connection between the lamp holders is achieved by the engagement of the limit pin and the inner positioning post, ensuring that all lamp holders are arranged smoothly along the arc of the outer guide rail. Then, the wire is threaded through the inner wire hole and connected to the plug interface to complete the power supply connection. Finally, the sealing and connection status of each component are checked. After confirming that everything is correct, it can be started and used. The operation process is convenient and can be adapted to the arc structure of the outer guide rail for flexible installation. The flexible connection design between the lamp holders improves installation compatibility, the sealing structure ensures the stability of use, and the reasonable layout of the inner wire hole and plug interface makes the wiring connection neat. The overall process takes into account practicality and safety, effectively maximizing the lighting effect of the grille light.
[0006] In a preferred embodiment, the lamp cavity includes a positioning seat and a hollowed-out protrusion. The positioning seat is located at the top inside the lamp cavity and is connected and fixed to the sealing cover by several sets of bolts through fixing holes. A set of wire holes for connecting external live wires is provided on the inner side of the middle position of the positioning seat. A set of wire tubes for conducting live wires is provided on the outer side of the wire holes. An upper support seat for positioning and fixing the wires is provided on the outer side of the middle position of the wire tube. An inner support seat for adjusting the tightness of the wire clamp is provided on the left and right sides of the lower end of the upper support seat. Two sets of inner support telescopic rods for adjusting the clamping gap width are provided on the inner side of the upper end of the inner support seat. The inner support telescopic rods are electro-hydraulic telescopic rods and are controlled by external control equipment. A lower support seat for connecting and fixing the wire clamp is provided at the lower end of each set of inner support seats.
[0007] In a preferred embodiment, the lower support base and the inner support base are fixedly connected by bolts. The lower support base is provided in two sets. Each set of the lower support base has a set of wire clamps at the bottom for improving the clamping and locking support of the live wire harness. The two sets of wire clamps are arranged in a mirror image. Each set of wire clamps has a set of inner insulating adhesive plates on the inner side for improving the internal insulation effect. The inner side of the inner insulating adhesive plates has several sets of hollow protrusions for stabilizing the clamping of the line and expanding the heat dissipation effect.
[0008] In a preferred embodiment, the hollow protrusions are rectangular in shape, and the left cross-section of each hollow protrusion is an arc-shaped convex structure. The wire clamps are movable and controlled by an internal support telescopic rod. The inner side of each hollow protrusion has a semi-circular arc-shaped wire control groove. When two sets of wire clamps hold a live wire, the hollow protrusions on both sides can stably clamp the live wire while providing clamping space to prevent damage. The hollow protrusions are evenly distributed, and a ventilation groove is provided between every two sets of hollow protrusions. A clamping cavity for holding the live wire is provided inside the space between two sets of wire clamps. Several sets of internal ventilation openings for dissipating heat are evenly distributed on the outer side of the wire clamps. These internal ventilation openings are interconnected with the ventilation grooves. During use, the wire clamps are first... Bolts connect and secure the positioning seat to the sealing cover via the fixing holes. Then, the external live wire is passed through the wire hole and the wire conduit. The upper support seat positions and supports the wire conduit. Adjusting the inner support telescopic rod of the inner support seat opens and closes the wire clamp on the lower support seat. The wire is placed into the clamping cavity between the two sets of wire clamps. Releasing the telescopic rod closes the wire clamp. Stable clamping of the wire is achieved through the inner insulating bonding plate and the hollow protrusions. The wire control groove of the hollow protrusion fits the wire, and the ventilation groove and inner ventilation opening form a heat dissipation channel, accurately achieving wire positioning, clamping, and insulation protection. The hollow protrusions and ventilation structure balance clamping stability and heat dissipation. The inner support telescopic rod can flexibly adjust the clamping tightness to adapt to different wire specifications. The overall operation is standardized and orderly, effectively ensuring the safety and stability of the circuit connection and extending the service life of the grille light.
[0009] In a preferred embodiment, the lamp body is located at the bottom of the middle position of the lower ends of the two sets of wire clamps. The lamp body includes a lower heat insulation plate and a lamp groove. The lower end of the lower heat insulation plate is bonded to the reflector with sealant. A set of LED driver modules for providing illumination is provided at the middle position of the upper end of the lower heat insulation plate. LED beads are provided at the bottom of the LED driver modules. The LED beads are sealed through the inside of the lamp groove and are located at the center position of the upper end of the inner side of the reflector. An inner heat insulation ring is provided on the outside of the LED driver module to keep it in place and prevent heat interference from the inside of the reflector. The inner heat insulation ring is a multi-layer structure composed of a ceramic fiber layer and an aluminum foil reflective layer. The inner heat insulation ring is located inside the lamp groove and covers the inner side of the reflector and the outer periphery of the upper end of the middle position of the lower heat insulation plate. A heat dissipation shell one for actively dissipating heat from the LED driver module is provided on the right side of the inner heat insulation ring, and a heat dissipation shell two for actively dissipating heat from the LED driver module is provided on the left side of the inner heat insulation ring.
[0010] In a preferred embodiment, both the first and second heat dissipation shells are semi-circular arc-shaped structures, forming a set of annular heat dissipation areas. Each of the first and second heat dissipation shells has a set of ventilation chambers for drawing heat from the lamp body. Inside each ventilation chamber are several sets of internal heat-conducting fans for uniform airflow. Each set of internal heat-conducting fans is a miniature fan that evenly distributes and distributes heat. Each set of internal heat-conducting fans has a set of exhaust holes for expelling external hot air. The top of the first and second heat dissipation shells has a set of positioning base plates for supporting the bottom of several sets of flexible limiting frames. The positioning base plates are fixed to the upper heat insulation plate by bolts. The top cross-section of the positioning base plate is a rectangular structure. The center of the positioning base plate has a set of internal holes for passing through live wires.
[0011] In a preferred embodiment, the positioning base plate has a set of side flexible support strips at each of its four corners for limiting and supporting several sets of flexible limiting frames. These side flexible support strips are steel wire rope structures, and there are four sets of them, each penetrating the four corners of the four sets of flexible limiting frames. The bottom of each side flexible support strip is fixedly connected to the positioning base plate, and the top of each side flexible support strip is fixedly connected to the uppermost flexible limiting frame, providing movable support. The top-view cross-sectional structure of the flexible limiting frame is the same as that of the positioning base plate, with the length and width increasing sequentially from top to bottom. Each set of flexible limiting frames has an inner hole at its center. These inner holes, the inner holes of the positioning base plate, and the center of the conduit are coaxial in a static state. The inner holes of the flexible limiting frames and the inner holes of the positioning base plate are all connected by an insulated wire bundle. The insulated wire bundle contains a live wire and is a flexible rubber structure. During use, the lower heat insulation plate and the reflector are first connected by a dense... After sealing and fixing with adhesive, the LED driver module is embedded inside the inner heat insulation ring, ensuring that the LED beads are sealed through the lamp slot and aligned with the center of the reflector. Then, heat sink one and heat sink two are installed on both sides of the LED driver module to form a circular heat dissipation area. Subsequently, the positioning base plate and the upper heat insulation plate are fixed with bolts. The assembly is completed by using the side flexible support strips passing through the four corners of the flexible limiting frame. The insulated wire harness is passed through the inner holes of the positioning base plate and the flexible limiting frame and connected to the LED driver module. During the use of the lamp body, the side flexible support strips can absorb vibration energy and buffer external impact forces, avoiding breakage or poor contact of the insulated wire harness due to rigid tension, thus playing an effective anti-vibration protection role. In addition, the four sets of symmetrically distributed side flexible support strips form a balanced limiting structure, restricting the lateral displacement of the flexible limiting frame, ensuring that the insulated wire harness always extends along the central axis of the inner hole, maintaining the regularity of the circuit connection, and avoiding the effect of flexible adjustment due to excessive tightness of the limiting, achieving a balance between support and flexible adaptation. The flexible limiting frame can be adaptively adjusted according to the deformation of the side flexible support strips.
[0012] After adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. The fitting of the limiting movable pin and the inner positioning column realizes the flexible connection between the lamp holders, ensuring that all lamp holders are arranged smoothly along the arc of the outer guide rail. Then, the wires are threaded through the inner wire hole and connected to the plug interface to complete the power supply connection. It can adapt to the arc structure of the outer guide rail to achieve flexible installation. The flexible connection design between the lamp holders improves the installation compatibility. The sealing structure can ensure the stability of use. The reasonable layout of the inner wire hole and the plug interface makes the wire connection neat. The overall process takes into account both practicality and safety, and effectively exerts the lighting effect of the grille light. 2. The inner insulating bonding plate and hollow protrusions on the inner side achieve stable clamping of the wires. The wire control groove of the hollow protrusion fits the wires, and the ventilation groove and the inner ventilation opening form a heat dissipation channel, which can accurately realize the positioning, clamping and insulation protection of the wires. The hollow protrusions and ventilation structure take into account both clamping stability and heat dissipation effect. The inner support telescopic rod can flexibly adjust the clamping tightness to adapt to different specifications of wires. The overall operation is standardized and orderly, effectively ensuring the safety and stability of the line connection and extending the service life of the grille light. 3. The inner heat insulation ring and double-layer heat insulation board can effectively block heat transfer. The circular heat dissipation area, combined with the internal heat conduction fan and exhaust hole, improves heat dissipation efficiency. The flexible limit frame and side flexible support strip ensure the stability and flexibility of the circuit connection. The insulation structure design enhances the safety of use. The overall process takes into account both the ease of assembly and the reliability of use, giving full play to the lighting and heat dissipation performance of the lamp body. 4. Four sets of symmetrically distributed side flexible support bars form a balanced limiting structure, restricting the lateral displacement of the flexible limiting frame and ensuring that the insulated wire harness always extends along the central axis of the inner hole, maintaining the regularity of the circuit connection. At the same time, it avoids affecting the flexible adjustment effect due to excessive tightness of the limiting, achieving a balance between support and flexible adaptation. The flexible limiting frame can adaptively adjust with the deformation of the side flexible support bars. When the lamp body is arranged along an arc, it compensates for the length deviation of the circuit through its own flexible deformation, avoiding excessive tension or bending of the circuit, and adapting to the installation requirements of different arc angles. The flexible limiting frame, side flexible support bars, and positioning base plate work together to form a multi-layer protective structure, which not only provides physical protection for the insulated wire harness, but also helps to disperse the heat of the circuit, and improves the heat dissipation effect in conjunction with the heat dissipation structure of the lamp cavity.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

First, open the sealing cover 22 of the lamp holder 2, accurately insert the flexible power take-off head of the lamp body 4 into the lamp cavity 28, and close the sealing cover 22 to keep the lamp cavity 28 sealed. Then, based on the arc angle of the outer guide rail 1, align the outer limiting seat 24 on the right side of the sealing shell 1 21 with the inner groove 201 of the sealing shell 27. The flexible connection between the lamp holders 2 is achieved by the engagement of the limiting movable pin 29 and the inner positioning post 26. Ensure all lamp holders 2 are smoothly arranged along the arc of the outer guide rail 1, then thread the wires through the inner wire hole 5, and connect the wires to the plug interface 6 to complete the power supply connection. Finally, check the sealing and connection status of each component. Once confirmed to be correct, it can be started and used.

Each set of internal heat-conducting fans 402 has a set of exhaust holes 403 for expelling external hot air. The top of heat dissipation shell 1 42 and heat dissipation shell 2 44 has a set of positioning base plates 46 for supporting the bottom of several sets of flexible limiting frames 47.

Each set of flexible limiting frames 47 has an inner hole in the middle. The inner holes of the sets of flexible limiting frames 47, the inner holes of the positioning base plate 46, and the center of the conduit 8d are coaxially arranged in the static state. Several sets of flexible limiting frames 47 and the inner holes of the positioning base plate 46 are all connected by insulated wire harnesses 49. The insulated wire harnesses 49 have live wires inside. The insulated wire harnesses 49 are a kind of flexible rubber structure. In use, the lower heat insulation plate 41 and the reflector 3 are first fixed together with sealant. The LED driver module 43 is embedded inside the inner heat insulation ring 404 to ensure that the LED beads are sealed through the lamp slot 405 and aligned with the center of the reflector 3. Then, the heat sink 1 42 and the heat sink 2 44 are installed on both sides of the LED driver module 43 to form a circular heat dissipation area. Then, the positioning base plate 46 and the upper heat insulation plate 45 are fixed with bolts. The side flexible support strips 48 pass through the four corners of the flexible limiting frame 47 to complete the assembly. The insulated wire harnesses 49 are passed through the inner holes of the positioning base plate 46 and the flexible limiting frame 47 and connected to the LED driver module 43. During the use of the lamp body 4, the side flexible support strip 48 can absorb vibration energy, buffer external impact force, and prevent the insulation wire harness 49 from breaking or poor contact due to rigid tension, thus playing an effective anti-vibration protection role. In addition, the four sets of symmetrically distributed side flexible support strips 48 form a balanced limiting structure, which restricts the lateral displacement of the flexible limiting frame 47, ensuring that the insulation wire harness 49 always extends along the central axis of the inner hole, maintaining the regularity of the line connection, and at the same time avoiding the effect of flexible adjustment due to excessive tightness of the limiting, thus achieving a balance between support and flexible adaptation. The flexible limiting frame 47 can be adaptively adjusted according to the deformation of the side flexible support strip 48. When the lamp body 4 is arranged along an arc, its own flexible deformation compensates for the length deviation of the line, avoiding excessive tension or bending of the line, and adapting to the installation requirements of different arc angles. The flexible limiting frame 47, together with the side flexible support strip 48 and the positioning base plate 46, forms a multi-layer protective structure, which not only provides physical protection for the insulated wire harness 49, but also helps to disperse the heat of the line. It works in conjunction with the heat dissipation structure of the lamp cavity 28 to improve the heat dissipation effect, while preventing external impurities from entering the line connection area and ensuring insulation performance. Through several sets of flexible limiting frames 47 and side flexible support strips 48, a multi-dimensional support and limiting is formed, which prevents the line from being affected by pulling, wear or vibration, effectively improving the installation compatibility, use stability and safety of the lamp body 4, and extending its service life.
