Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and in particular to a planar light microstructure through-taillight structure. Background Technology
[0002] With the advancement of aesthetics and trends, continuous taillights have become increasingly popular as a design trend in automotive taillights. A continuous taillight connects the original two separate sets of taillights on the left and right into a single, elongated strip. A popular design currently features a logo with backlighting in the center of the taillight, with the taillights symmetrically distributed around the logo area, spanning the entire rear of the vehicle, either the tailgate or the trunk lid. To achieve optimal lighting effects, the fixed distribution of the light guide and LED light source is crucial. Currently, light guides and LEDs are typically laid flat along the entire horizontal length. While this ensures uniform light emission, installing them within a limited space presents a significant challenge, requiring both effective illumination and stable installation. Utility Model Content
[0003] The purpose of this invention is to design a planar light microstructure through-taillight structure to overcome the shortcomings of the above-mentioned technologies.
[0004] This utility model designs a planar light microstructure through-type taillight structure, including a bottom shell, a face mask on the bottom shell, and a mounting cavity formed between the bottom shell and the face mask. A decorative frame is provided in the mounting cavity, and a mounting groove is opened on the front of the decorative frame. A light guide assembly is provided in the mounting groove. The light guide assembly includes a frame, light guide sheets, and a light guide plate. The frame is connected to the decorative frame, and several light guide sheets are evenly distributed along the length of the decorative frame. The light guide plate corresponds one-to-one with the light guide sheets and is located on the back of the light guide sheets. Both the light guide sheets and the light guide plate are mounted on the frame.
[0005] Preferably, the central area of the decorative frame is a logo area for setting the logo, and two mounting slots are symmetrically distributed on the decorative frame with the logo area as the center, and each mounting slot is provided with a light guide component.
[0006] Further optimization has been achieved, with each frame and light guide plate within the same mounting slot being set up in a one-to-one correspondence.
[0007] Further optimization involves an inner wall slot on the mounting groove, with the bottom of the frame mounted on the slot. A retaining edge extends from the front of the frame, and a limiting strip is provided between the retaining edge and the inner peripheral wall of the frame. A first stepped surface is formed between the retaining edge and the limiting strip, and a second stepped surface is formed between the limiting strip and the inner peripheral wall. A limiting block is provided at the bottom of the inner peripheral wall of the frame. One end of the limiting strip extends above the limiting block and forms a gap with the limiting block. A third stepped surface is provided on the limiting block. The periphery of the light guide sheet is snapped onto the first stepped surface, and the bottom of the light guide sheet has a protrusion that snaps onto the gap. The periphery of the light guide plate is snapped onto the second stepped surface, and the bottom of the light guide plate has a notch that snaps onto the third stepped surface.
[0008] Further optimization involves inserting the bottom of each frame into the slot below, with an integrated mounting ear at the bottom of the frame and mounting holes on the mounting ear. The decorative frame has a screw post at the bottom of the slot, and the mounting holes and screw posts are connected by fasteners, making the frame and decorative frame detachable.
[0009] Further optimization involves overlapping the head and tail of two adjacent light guides within the same mounting slot, and staggering all light guides sequentially along the length of the decorative frame.
[0010] Further optimization involves the width of the decorative frame gradually increasing from the center to the outside, and correspondingly, the shape of the light guides distributed in the mounting groove gradually increases proportionally from the center to the outside of the decorative frame.
[0011] Preferably, the decorative frame is further provided with a PCB board and a driving component, the driving component and the PCB board are electrically connected, the PCB board is provided with LEDs, and the PCB board and the LEDs are electrically connected.
[0012] Further optimization involves distributing multiple PCBs circumferentially along the mounting slots, with LEDs arranged in a matrix on each PCB.
[0013] Preferably, the light guide sheet is a thin-walled light guide structure, and the surface of the light guide sheet is provided with light guide patterns.
[0014] The technical advantage of this invention is that several light guide sheets are distributed sequentially along the length of the decorative frame, symmetrically distributed on both sides with the central logo area of the decorative frame as the center. The width of the decorative frame and the base shell gradually increases from the center to the outside. Correspondingly, the shapes of the light guide sheets also gradually increase in proportion. Then, the PCB board and LEDs are distributed along the circumference of the decorative frame, allowing the LED light source to be introduced from the side. Combined with the matrix arrangement of the LEDs, a uniform and consistent lighting effect is achieved. At the same time, the entire taillight has a smooth, flowing, and continuous gradient curve shape, which is not only aesthetically pleasing. Furthermore, the taillights offer enhanced illumination and warning functions, thus improving driving safety. The light guides and light guide plates are one-to-one and fixedly mounted on the frame. The inner circumference of the frame has stepped surfaces that limit the movement of the light guides and light guide plates, simplifying the structure and enhancing the stability of their installation. All light guides are staggered along the length of the decorative frame, creating a visually layered lighting effect. The light guides are also thin-walled structures with a thickness of millimeters, minimizing space occupancy. The overall design is flat and streamlined, aligning with the principles of low wind resistance and integrated design. Attached Figure Description

[0027] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0028] This utility model includes a base shell 1, a face shield 2 on the base shell 1, and a mounting cavity 11 formed between the base shell 1 and the face shield 2. A decorative frame 3 is provided inside the mounting cavity 11. The decorative frame 3 is elongated in shape along its length. The central area of the decorative frame 3 is a logo area 7 for setting the logo. It can be understood that the decorative frame 3 includes the central logo area 7 and two main body parts symmetrically distributed around the logo area 7. A mounting groove 31 is provided on the front of the decorative frame 3. The two mounting grooves 31 are symmetrically distributed on the main body parts of the decorative frame 3 around the logo area 7. The shape of the mounting grooves 31 conforms to the shape of the main body parts of the decorative frame 3, and the openings of the mounting grooves 31 face the front of the decorative frame 3.
[0029] In this embodiment, the width of the decorative frame 3 gradually increases from the center to the outside, so that the outer contour of the decorative frame 3 forms a smooth, smooth and continuous gradient curve shape. Correspondingly, the shape of the mounting groove 31 is adapted to the shape of the decorative frame 3. The decorative frame 3 is installed in the bottom shell 1, and the faceplate 2 is covered on the bottom shell 1, so that the overall taillight structure of this utility model has a gradient curve shape, presenting a unique aesthetic appearance of the taillight with rich layers and fashionable design.
[0030] Each mounting slot 31 is provided with a light guide assembly, which includes a frame 4, a light guide sheet 5, and a light guide plate 6. The frame 4 is installed in the mounting slot 31. Several light guide sheets 5 in the same mounting slot 31 are evenly distributed along the length direction of the mounting slot 31, which is also the length direction of the decorative frame 3. The light guide plate 6 in the same mounting slot 31 corresponds one-to-one with the light guide sheet 5 and is located on the back of the light guide sheet 5. Both the light guide sheet 5 and the light guide plate 6 are installed on the frame 4. There can be one frame 4, which extends along the length direction of the mounting slot 31. Several light guide sheets 5 are arranged and installed on the frame 4 in sequence. There can also be multiple frames 4. In this embodiment, there are multiple frames 4, which correspond one-to-one with the light guide sheet 5 and the light guide plate 6. That is, each frame 4 is equipped with one light guide sheet 5 and one light guide plate 6.
[0031] Furthermore, a slot 32 is provided at the bottom of the inner wall of the mounting groove 31. The bottom of the frame 4 is inserted into the slot 32. The overall shape of the frame 4 is consistent with that of the light guide sheet 5. The frame 4 extends circumferentially along the light guide sheet 5. A baffle 41 extends from the front of the frame 4. A limiting strip 42 is provided between the baffle 41 and the inner peripheral wall of the frame 4. The limiting strip 42 is set along the extension direction of the frame 4. A first stepped surface 43 is formed between the baffle 41 and the limiting strip 42. A second stepped surface 44 is formed between the limiting strip 42 and the inner peripheral wall. The first stepped surface 43 and the second stepped surface 44 are arranged side by side, and the first stepped surface 43 is located in front of the second stepped surface 44. A limiting block 45 is provided at the bottom of the inner peripheral wall of the frame 4. In this embodiment, limiting blocks 45 are provided on both sides of the bottom of the inner peripheral wall of the frame 4. The limiting strip 42 and the limiting block 45 are integrally formed with the inner wall of the frame 4. The two ends of the limiting strip 42 extend above the corresponding limiting block 45 and form a gap 46 with the limiting block 45. The limiting block 45 is provided with a third stepped surface 47, which is located behind the gap 46. The periphery of the light guide sheet 5 is snapped into the first stepped surface 43. Due to the limiting of the front edge 41, the light guide sheet 5 is stably snapped into the first stepped surface 43. The bottom two sides of the light guide sheet 5 are provided with protrusions 51, which correspond to the gap 46 and are snapped into the gap 46, thereby forming a limiting. The periphery of the light guide plate 6 is snapped into the second stepped surface 44. Due to the limiting of the front limiting strip 42, the light guide plate 6 is stably snapped into the second stepped surface 44. The bottom two sides of the light guide plate 6 are provided with notches 61, which are snapped into the third stepped surface 47. Therefore, the light guide sheet 5 and the light guide plate 6 can be installed side by side and stably on the frame 4.
[0032] Furthermore, the bottom of the mounting groove 31 is a plate structure, and the slot 32 is opened in the plate structure and penetrates the plate structure. The bottom of each frame 4 is inserted into the lower part of the slot 32, that is, the bottom of the frame 4 is located below the plate structure. The bottom of the frame 4 is provided with an integrated mounting ear 48, which is set on the same side as the limiting block 45. The mounting ear 48 extends out from the outer wall of the frame 4, and the mounting ear 48 is provided with a mounting hole 49. The decorative frame 3 is provided with a screw hole post 33 at the bottom of the slot 32, that is, the bottom of the plate structure is provided with a screw hole post 33. The mounting hole 49 and the screw hole post 33 are connected by a fastener 410, so that the frame 4 and the decorative frame 3 form a detachable connection.
[0033] Furthermore, the head and tail of two adjacent light guide sheets 5 in the same mounting groove 31 overlap. In this embodiment, the light guide sheet 5 is trapezoidal, and the top edge of the trapezoid is inclined. When multiple light guide sheets 5 are arranged along the length of the decorative frame 3, their top edges form a direction that conforms to the shape of the frame of the decorative frame 3. All the light guide sheets 5 are staggered one after the other along the length of the decorative frame 3, creating a visually layered light effect.
[0034] Furthermore, since the width of the decorative frame 3 gradually increases from the center to the outside, the shape of the light guide 5 distributed in the mounting groove 31 gradually increases proportionally from the center to the outside of the decorative frame 3, so that the taillight forms a gradually larger and streamlined light effect.
[0035] The decorative frame 3 is also equipped with a PCB board 8 and a driver 9. The driver 9 and the PCB board 8 are electrically connected. The PCB board 8 is equipped with LEDs 10, and the PCB board 8 and the LEDs 10 are electrically connected. There are two driver 9s, which are set one-to-one with the light guide components. The driver 9s are fixed on the back of the decorative frame 3. Multiple PCB boards 8 are distributed around the circumference of the mounting groove 31. The LEDs 10 are arranged in a matrix on each PCB board 8, so that the LED light source is introduced from the side. Combined with the matrix arrangement of the LEDs 10, a uniform and consistent lighting effect is achieved.
[0036] Furthermore, the logo area 7 can be equipped with a PCB board 8 and LED 10 to serve as the background light for the logo, thereby enhancing its aesthetic appeal.
[0037] Furthermore, the light guide sheet 5 is a thin-walled structure, typically less than ten millimeters thick, occupying little space and forming a flat, streamlined design that aligns with the modern automotive trend toward low wind resistance and integrated aesthetics.
[0038] The surface of the light guide sheet 5 is decorated with light guide patterns. The light guide patterns are hemispherical and very small in size, covering the entire surface of the light guide sheet 5. This creates an optical microstructure pattern on the surface of the light guide sheet 5, breaking the limitation of the traditional taillight design. The through-type design enhances the visual continuity and spatial layering. The design is novel, unique, and highly creative, with a strong visual impact, significantly improving the vehicle's recognizability and aesthetics.
[0039] In this utility model, the mask 2 serves as a closed shell and is also used to optimize the effect. The decorative frame is used to fix and install the PCB board 8, the driving component 9 and the frame 4. The frame 4 is used to fix the light guide sheet 5 and the light guide plate 6. The bottom shell 1 is used to fix the decorative frame 3 and the mask 2. The light guide sheet 5 has the function of uniform light effect. The driving component 9 is used to stabilize the voltage and current of the PCB board 8. The PCB board 8 is used to control the switch LED 10.
[0040] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
