Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a metal microporous light-transmitting and light-emitting threshold. Background Technology

[0002] As automobiles become a durable consumer good, they are gradually entering ordinary households. In recent years, the number of cars in China has grown rapidly. Most cars are equipped with metal panels on the front door sills for decoration and identification. As the automotive industry responds to increasingly fierce market competition, illuminated door sill trims have promising development prospects.

[0003] The existing structure does not have a light-emitting structure. In the case of night or in environments with poor visibility, people inside the vehicle may trip when getting on or off. In addition, the sill surface does not have a friction-resistant and anti-slip function, and it is easy to slip when stepping on it in the rain, which may lead to accidents.

[0004] A search revealed that Chinese patent CN210761003U discloses an embedded front sill metal panel with a light-emitting structure. This mechanism incorporates an LED light panel within the panel's light-emitting groove. When the LED light panel emits light, the light passes through the explosion-proof glass, providing illumination and signage, enhancing safety when people enter and exit the vehicle. Furthermore, an inner protective edge, circularly arranged at the bottom edge of the protective cover, completely encloses the panel, protecting it and providing friction and anti-slip properties on the car sill. When the panel is pressed down, the limiting lock block retracts into the limiting cavity. After the panel is pressed to the installation position, the limiting lock block expands to both ends under the action of a return spring, completing the installation. For disassembly, simply use the anti-slip strip to push the limiting lock block into the limiting cavity, then lift the panel upwards; no additional tools are required, making installation and disassembly convenient.

[0005] However, in actual use, when the LED light panel is turned on, the light passes through the explosion-proof glass to serve as illumination and signage, but it cannot adjust the illumination area of ​​the light. This results in limited practicality in some different usage scenarios. In a dimly lit parking lot, a wider illumination range is needed to better see the surrounding environment, while in a relatively well-lit environment, a smaller illumination area may be sufficient for simple prompts. The fixed illumination area is difficult to meet diverse needs. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal microporous light-transmitting and light-emitting threshold to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A metal microporous light-transmitting and light-emitting threshold includes a metal frame, a light-emitting groove is formed on the surface of the metal frame, an LED light board is fixedly installed inside the light-emitting groove, one end of the LED light board is electrically connected to a wire, a terminal block is fixedly installed on one side of the metal frame, and an adjustment mechanism is provided inside the metal frame.

[0009] The adjustment mechanism includes multiple fixing slots formed on the surface of a metal frame. Each fixing slot has a fixing plate connected to it by bolts. A micro-perforated panel is fixed to one end of each fixing plate. An adjustment plate is fixed to the bottom of the micro-perforated panel. The adjustment plate has a sliding groove inside, and an adjustment frame is slidably arranged inside the sliding groove. Multiple light-emitting holes are formed on the surface of the adjustment plate. A light guide plate is fixed to the bottom of the adjustment plate. One end of the wire passes through the metal frame and the terminal block sequentially and extends outward from the terminal block. The fixing slot is located on one side of the light-emitting slot. A movable slot is formed on the surface of the metal frame. The adjustment frame is slidably connected to the movable slot. A locking groove is formed inside the metal frame, and a U-shaped frame is engaged inside the locking groove.

[0010] By adopting the above technical solution, the LED light panel, light guide plate and micro-perforated panel are combined to make the threshold surface present a uniform and soft light emission effect. With the help of the adjustment frame sliding in the movable groove, the light hole blockage can be adjusted as needed, the illumination area can be flexibly controlled, and the overall structure is stable, reliable and highly practical.

[0011] As a further description of the above technical solution: the metal frame is provided with an installation mechanism, the installation mechanism includes two installation slots opened inside the metal frame, two springs are fixedly installed inside each of the two installation slots, a T-shaped movable plate is fixedly installed at one end of the two springs, a protrusion is provided at the top of the T-shaped movable plate, one end of the protrusion extends through the metal frame and outward from the metal frame, and two through slots are opened on the surface of the T-shaped movable plate and the metal frame.

[0012] By adopting the above technical solution, the spring and the T-shaped movable plate can be used to automatically fix the door during installation, which is easy to operate. Moreover, the protruding block structure on the T-shaped movable plate can enhance the connection stability with the installation position and effectively prevent the door sill from loosening and shifting.

[0013] As a further description of the above technical solution: U-shaped fixing frames are inserted into the interior of both through slots. Two threaded holes are opened on the surface of both the U-shaped fixing frames and the metal frame. Bolts are threaded into the interior of both threaded holes. An infrared sensor and a brightness sensor are embedded in the surface of the metal frame. The infrared sensor is located on one side of the brightness sensor. A controller is fixedly installed on one side of the metal frame.

[0014] By adopting the above technical solution, infrared sensors and brightness sensors can perceive the surrounding environment in real time. Combined with the controller, intelligent control can be achieved, and the light emission status can be automatically adjusted according to the environment, which not only saves energy but also enhances the convenience and user-friendly experience.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up an adjustment mechanism, compared with the existing technology, the ingenious sliding connection structure between the light guide plate, the adjustment frame, and the metal frame enables fine adjustment of the horizontal position of the micro-perforated panel. This allows for flexible control of the light irradiation area. The adjustment frame can be moved to a position that does not block the light outlet or only slightly blocks it, allowing the light to pass through the micro-perforated panel as much as possible and diffuse outward, maximizing the irradiation area and providing sufficient illumination. Furthermore, the U-shaped frame with slots inside the metal frame can limit the range of motion of the adjustment frame, ensuring that the position of the micro-perforated panel remains stable and reliable during adjustment and use, thus ensuring the stability and uniformity of the light output.

[0017] 2. By setting up an installation mechanism, compared with existing technologies, during the installation process, after aligning the fixing plate with the fixing groove on the surface of the metal frame, bolts can be used to complete the fixation. Through the cooperation of the fixing plate and the fixing groove, the installation position of the microporous panel on the metal frame can be accurately guaranteed. Then, by pressing down, it drives the T-shaped movable plates on both sides to move downward and retract into the installation groove. At the same time, the design of compressing the spring deformation makes full use of the elastic potential energy of the spring to achieve the automatic fixing function. When the T-shaped movable plate is fully inserted into the external installation position, the elasticity of the spring will push the T-shaped movable plate to insert into the external installation position. This automatic return and insertion fixing method is not only simple to operate, but also can quickly and firmly install the metal frame in the corresponding position without the need for additional complex tools or excessive manual intervention.

[0026] 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.

[0027] The embodiments disclosed in this application are as follows: Figure 1-7 The metal microporous light-transmitting and light-emitting threshold includes a metal frame 1, a light-emitting groove 2 is opened on the surface of the metal frame 1, an LED light board 3 is fixedly installed inside the light-emitting groove 2, one end of the LED light board 3 is electrically connected to a wire 4, a terminal block 5 is fixedly installed on one side of the metal frame 1, and an adjustment mechanism is installed inside the metal frame 1.

[0028] The adjustment mechanism includes multiple fixing slots on the surface of the metal frame 1. Each fixing slot has a fixing plate 6 bolted to its interior. A micro-perforated panel 7 is fixed to one end of each fixing plate 6. An adjustment plate 8 is fixed to the bottom of the micro-perforated panel 7. A sliding groove is formed inside the adjustment plate 8, and an adjustment frame 9 is slidably mounted inside the groove. Multiple light-emitting holes 10 are formed on the surface of the adjustment plate 8. A light guide plate 11 is fixed to the bottom of the adjustment plate 8. One end of the wire 4 passes through the metal frame 1 and the terminal block 5 sequentially and extends outward from the terminal block 5. The fixing slot is located on one side of the light-emitting slot 2. A movable slot 12 is formed on the surface of the metal frame 1, and the adjustment frame 9 is slidably connected to the movable slot 12. A locking groove is formed inside the metal frame 1, and a U-shaped frame 13 is engaged inside the locking groove. After installation, the LED light panel 3 is guided through the light guide... Line 4 connects to the external vehicle connector. When a suitable power supply is connected, the numerous LED beads on the LED light panel 3 start to work and emit light. The emitted light propagates in the direction of the micro-perforated panel 7, preparing for subsequent light transmission and emission. The light emitted from the LED light panel 3 first shines on the light guide plate 11. The light guide plate 11 is made of transparent acrylic material and has the function of evenly dispersing and guiding the propagation of light. It performs operations such as refraction and reflection on the light, so that the light can be evenly distributed inside the light guide plate 11 and changes the direction of light propagation, making it propagate in the direction of the light outlet 10. The evenly distributed light is emitted through multiple light outlet holes 10 on the surface of the adjustment plate 8, and then shines through the micro-holes on the micro-perforated panel 7 to the outside, so that the entire threshold surface presents a uniform and soft light emission effect.

[0029] The adjusting plate 8 has a sliding groove inside, within which the adjusting frame 9 can slide. Simultaneously, the adjusting frame 9 is slidably connected to the movable groove 12 on the surface of the metal frame 1. This allows the adjusting plate 8 to move the micro-aperture panel 7 to a certain extent in the horizontal direction. By pulling the U-shaped frame 13 upwards, it is removed from the slot. Then, the adjusting frame 9 is pulled to move within the movable groove 12, thereby blocking part of the light-emitting hole 10 on the surface of the adjusting plate 8. Thus, the horizontal position of the micro-aperture panel 7 can be finely adjusted by sliding the adjusting frame 9 according to actual needs, thereby controlling the irradiation area. Furthermore, the U-shaped frame 13, engaged by the slot inside the metal frame 1, limits the range of motion of the adjusting frame 9, ensuring that the position of the micro-aperture panel 7 remains stable and reliable during adjustment and use, thus ensuring the stability and uniformity of the emitted light.

[0030] Reference Figure 2-4As shown, the metal frame 1 has an internal mounting mechanism, which includes two mounting slots 14 inside the metal frame 1. Two springs 15 are fixedly installed inside each mounting slot 14. A T-shaped movable plate 16 is fixedly installed at one end of each spring 15. A protrusion is provided on the top of the T-shaped movable plate 16. One end of the protrusion extends through the metal frame 1 and outwards. Two through slots 17 are provided on the surface of the T-shaped movable plate 16 and the metal frame 1. When the metal frame 1 is moved to the mounting position and then pressed down, the metal frame 1 drives the T-shaped movable plates 16 on both sides to move downwards and retract into the mounting slots 14. At this time, the springs 15 are also deformed. When the T-shaped movable plate 16 is fully inserted into the external mounting position, the force on the T-shaped movable plate 16 is released. Then, the elasticity of the springs 15 pushes the T-shaped movable plate 16 into the external mounting position. Since the T-shaped movable plate 16 is T-shaped inside the mounting slot 14, it effectively prevents the T-shaped movable plate 16 from falling out of the mounting slot 14, thereby improving the overall stability.

[0031] Next, insert the U-shaped fixing frame 18 into the through groove 17 on the surface of the metal frame 1, so that part of the U-shaped fixing frame 18 is inside the metal frame 1 and in contact with the T-shaped movable plate 16, and the other part is exposed outside. Then, by screwing the bolts 19 into the corresponding threaded holes, the U-shaped fixing frame 18 is further fixed to the metal frame 1 to ensure the firmness of the installation.

[0032] Reference Figure 5-7 As shown, U-shaped fixing frames 18 are inserted into the interior of both through slots 17. Two threaded holes are opened on the surface of both U-shaped fixing frames 18 and metal frame 1. Bolts 19 are threaded into the interior of both threaded holes. An infrared sensor 20 and a brightness sensor 21 are embedded in the surface of metal frame 1. The infrared sensor 20 is located on one side of the brightness sensor 21. A controller 22 is fixedly installed on one side of metal frame 1. The infrared sensor 20 and brightness sensor 21 embedded in the surface of metal frame 1 play an important role. The infrared sensor 20 can detect the movement of a human body approaching or leaving the threshold. When someone approaches the threshold, the infrared sensor 20 will receive the infrared signal emitted by the human body and transmit the corresponding electrical signal to the controller 22 fixedly installed on the side. The brightness sensor 21 monitors the brightness of the surrounding environment in real time and also feeds back the detected brightness signal to the controller 22.

[0033] Based on the received signals, when the environment is dark and someone is detected approaching, the controller 22 can control the LED light panel 3 to turn on to provide lighting for people passing by; when people leave for a period of time or the ambient brightness reaches a certain level, the controller 22 can control the LED light panel 3 to turn off, achieving the effects of energy saving and intelligent control of light emission according to the actual scene.

[0034] Working principle of this utility model:

[0035] This invention relates to a metal microporous light-transmitting and light-emitting threshold. When using this device...

[0036] Preparation: During installation, the micro-hole panel 7 is initially connected to the metal frame 1 via the fixing piece 6. The fixing piece 6 is aligned with the fixing groove on the surface of the metal frame 1 and fixed with bolts to fix the position of the micro-hole panel 7. The LED light board 3 is powered on by connecting the wire 4 set on one side of the terminal block 5 to the external vehicle connector.

[0037] Next, the metal frame 1 is moved to the installation position, and then the metal frame 1 is pressed down. The metal frame 1 drives the T-shaped movable plates 16 on both sides to move downward and retract into the installation groove 14. At this time, the spring 15 is also compressed and deformed. When the T-shaped movable plate 16 is fully inserted into the external installation position, the force on the T-shaped movable plate 16 is released. Then, the elasticity of the spring 15 pushes the T-shaped movable plate 16 into the external installation position. Since the T-shaped movable plate 16 is set in a T-shape inside the installation groove 14, it effectively prevents the T-shaped movable plate 16 from falling out of the installation groove 14, thereby improving the overall stability.

[0038] Next, insert the U-shaped fixing frame 18 into the through groove 17 on the surface of the metal frame 1, so that part of the U-shaped fixing frame 18 is inside the metal frame 1 and in contact with the T-shaped movable plate 16, and the other part is exposed outside. Then, by screwing the bolts 19 into the corresponding threaded holes, the U-shaped fixing frame 18 is further fixed to the metal frame 1 to ensure the firmness of the installation.

[0039] After installation, the LED light panel 3 is connected to the external vehicle connector via wire 4. When a suitable power supply is connected, the numerous LED beads on the LED light panel 3 begin to work and emit light. The emitted light propagates in the direction of the micro-perforated panel 7, preparing for subsequent light transmission and emission. The light emitted from the LED light panel 3 first shines on the light guide plate 11. The light guide plate 11 is made of transparent acrylic material and has the function of evenly dispersing and guiding the propagation of light. It performs operations such as refraction and reflection on the light, so that the light can be evenly distributed inside the light guide plate 11 and changes the direction of light propagation, making it propagate in the direction of the light outlet 10. The evenly distributed light is emitted through multiple light outlets 10 on the surface of the adjustment plate 8, and then shines through the micro-holes on the micro-perforated panel 7 to the outside, so that the entire threshold surface presents a uniform and soft light emission effect.

[0040] The adjustment plate 8 has a sliding groove inside, and the adjustment frame 9 can slide in the sliding groove. At the same time, the adjustment frame 9 is slidably connected to the movable groove 12 on the surface of the metal frame 1. This allows the adjustment plate 8 to move the micro-hole panel 7 in a certain range in the horizontal direction. By pulling the U-shaped frame 13 upward, the U-shaped frame 13 is taken out from the slot. Then, the adjustment frame 9 is pulled to move inside the movable groove 12, thereby causing the adjustment frame 9 to block part of the light-emitting hole 10 opened on the surface of the adjustment plate 8. Thus, the position of the micro-hole panel 7 in the horizontal direction can be finely adjusted by sliding the adjustment frame 9 according to actual needs, thereby controlling the irradiation area. In addition, the U-shaped frame 13, which is engaged by the slot inside the metal frame 1, can limit the range of motion of the adjustment frame 9, ensuring that the position of the micro-hole panel 7 remains stable and reliable during adjustment and use, and ensuring the stability and uniformity of light emission.

[0041] The infrared sensor 20 and brightness sensor 21 embedded in the surface of the metal frame 1 play an important role. The infrared sensor 20 can detect the movement of a human body approaching or leaving the threshold. When someone approaches the threshold, the infrared sensor 20 will receive the infrared signal emitted by the human body and transmit the corresponding electrical signal to the controller 22 fixed nearby. The brightness sensor 21 monitors the brightness of the surrounding environment in real time and will also feed back the detected brightness signal to the controller 22. Based on these received signals, when the environment is dark and someone is detected approaching, the controller 22 can control the LED light panel 3 to turn on to provide lighting for people passing by; when people leave for a period of time or the ambient brightness becomes bright enough, the controller 22 can control the LED light panel 3 to turn off, achieving the effects of energy saving and intelligent control of light emission according to the actual scene.

[0042] It is worth noting that the infrared sensor 20 is an HC-SR50 infrared sensor, the brightness sensor 21 is a BH1750FVI brightness sensor, and the controller 22 is an STM32F103C8T6 controller. All of these are existing technologies and will not be described in detail in this technical solution.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
