Description

Technical Field

[0001] This utility model relates to a taillight, specifically a dynamic light-emitting taillight for automobiles, belonging to the field of automotive taillight technology. Background Technology

[0002] Car taillights are an important functional component of automobiles, playing a crucial role in indicating direction during driving. On one hand, car lights serve as warnings and signals to ensure driving safety; on the other hand, they complement the car's exterior, adding a finishing touch to its design and satisfying customers' desire for personalized decoration and structural customization.

[0003] A car taillight disclosed in Chinese patent application publication CN218565269U features a housing and a lamp cover. The housing has multiple partitions inside, which divide the interior into multiple lamp cavities. Each lamp cavity contains a second mounting plate, a lamp plate, and a lamp chip. The bottom of the second mounting plate has a defogging structure, which includes a housing, a motor, a fan blade, and a heating wire. When fog appears inside the taillight, it can be defogged through the defogging structure to ensure the brightness and transparency of the taillight.

[0004] The solutions in the above patents can use a defogging structure to defog and ensure the brightness of the taillights. However, the defogging structure can only keep the lamp cover clean and transparent. In foggy environments, the light will be scattered by the fog, making it difficult to clearly identify the traffic lights at a distance. This can easily cause drivers to not be able to see the traffic lights, thus seriously affecting traffic efficiency.

[0005] Therefore, a dynamic illuminated taillight for automobiles is proposed here. Utility Model Content

[0006] This invention proposes a dynamic luminous taillight for automobiles, which can improve the penetrating power of the taillight in heavy fog, making it easier for drivers to see the traffic lights.

[0007] This utility model is achieved through the following technical solution: a dynamic light-emitting taillight for automobiles, including a lamp housing and a lamp cover installed on the right side of the lamp housing, wherein the lamp housing is provided with an adjustment component.

[0008] The adjustment assembly includes a second mounting plate and a transparent plate fixed to the inner wall of the lamp housing, with the transparent plate located to the right of the second mounting plate. A first mounting plate is fixed to the side of the second mounting plate near the transparent plate. An electric push rod is fixed to the inner wall of the hole in the second mounting plate. A fixing plate is fixed to the output end of the electric push rod, and the fixing plate is located between the first mounting plate and the transparent plate.

[0009] A fixing shell is fixed to the side of the second mounting plate away from the transparent plate. A fixing rod is fixed to the side of the fixing plate away from the transparent plate. One end of the fixing rod passes through the first mounting plate and the second mounting plate in sequence and extends into the interior of the fixing shell. Holes adapted to the fixing rod are opened on both the second mounting plate and the first mounting plate. A sliding plate is fixed to the end of the fixing rod inside the fixing shell. The outer surface of the sliding plate is slidably connected to the inner wall of the fixing shell. Connecting pipes are fixedly connected to both the upper and lower sides of the fixing shell. The end of the connecting pipe away from the fixing shell is fixedly connected to the transparent plate.

[0010] Furthermore, a fixing block is fixed to the upper surface of the fixing rod, and the inner wall of the hole of the fixing block is fixed to the outer surface of the electric push rod.

[0011] Furthermore, a limiting rod is fixed on the side of the fixing plate away from the transparent plate, and the outer surface of the limiting rod is slidably connected to the inner wall of the hole in the second mounting plate. Both the second mounting plate and the first mounting plate are provided with holes that are compatible with the limiting rod.

[0012] Furthermore, multiple LED beads are installed on the side of the first mounting plate near the fixing plate, and multiple arc-shaped protrusions are provided on the side of the fixing plate away from the first mounting plate, with the LED beads located on the same horizontal line.

[0013] Furthermore, a controller is installed on the inner wall of the lamp housing, and the controller is electrically connected to the electric push rod. Hydraulic medium is provided inside the transparent plate.

[0014] Furthermore, the outer surface of the lamp housing is fixed with multiple mounting ears, and each mounting ear is provided with a mounting hole.

[0015] This utility model provides a dynamic luminous taillight for automobiles, which has the following beneficial effects:

[0016] 1. In foggy weather, the controller activates an electric push rod, which moves a fixed plate and an arc-shaped protrusion. The protrusion moves away from the LEDs to a suitable position, allowing the light emitted by multiple LEDs to be refracted into a highly focused beam. This refracts the dispersed light from the LEDs into multiple focused beams, improving the taillight's penetration in fog and making it easier for drivers to see the traffic lights. Simultaneously, the movement of the fixed plate causes a sliding plate to move along the inner wall of the fixed housing via a fixed rod, creating a pressure difference. At this time, the hydraulic medium inside the transparent plate enters the fixed housing through a connecting pipe. Because the hydraulic medium is drawn into the fixed housing, the transparent plate loses pressure, causing a concave shape in the center. This creates a concave mirror between the transparent plate and the hydraulic medium inside, increasing the radiation angle of the multiple focused beams and thus improving their radiation range.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0026] Please see Figures 1-4 This utility model provides a dynamic light-emitting taillight for automobiles, including a lamp housing 1 and a lamp cover 3 installed on the right side of the lamp housing 1. An adjustment component 2 is provided inside the lamp housing 1, and a fog sensor is installed inside the lamp housing 1.

[0027] The inner wall of the lamp housing 1 is equipped with a controller 4. The electric push rod 201 and the haze sensor are both electrically connected to the controller 4. The controller 4 can be an STM32 microcontroller.

[0028] Multiple mounting ears 101 are fixed on the outer surface of the lamp housing 1, and each mounting ear 101 has a mounting hole.

[0029] Please refer to this carefully. Figure 3 and Figure 4The adjustment component 2 includes a second mounting plate 209 and a transparent plate 203 fixed to the inner wall of the lamp housing 1. The transparent plate 203 is located to the right of the second mounting plate 209. A cavity is opened inside the transparent plate 203. A hydraulic medium 214 is disposed inside the transparent plate 203. The hydraulic medium 214 is transparent and can be Kunlun brand L-HM46 colorless transparent hydraulic oil. A first mounting plate 208 is fixed to the side of the second mounting plate 209 near the transparent plate 203. An electric push rod 201 is fixed to the inner wall of the hole of the second mounting plate 209. A fixing plate 202 is fixed to the output end of the electric push rod 201. The fixing plate 202 is located between the first mounting plate 208 and the transparent plate 203.

[0030] A fixing block 211 is fixed to the upper surface of the fixing rod 205, and the inner wall of the hole of the fixing block 211 is fixed to the outer surface of the electric push rod 201.

[0031] A limiting rod 207 is fixed on the side of the fixed plate 202 away from the transparent plate 203, and the outer surface of the limiting rod 207 is slidably connected to the inner wall of the hole in the second mounting plate 209. Holes adapted to the limiting rod 207 are opened on both the second mounting plate 209 and the first mounting plate 208.

[0032] Multiple LED beads 212 are installed on the side of the first mounting plate 208 near the fixed plate 202. Multiple arc-shaped protrusions 213 are provided on the side of the fixed plate 202 away from the first mounting plate 208. The LED beads 212 are located on the same horizontal line. The transparent plate 203, the fixed plate 202 and the arc-shaped protrusions 213 can all be made of high-transparency acrylic material.

[0033] In foggy weather, the fog sensor detects the visibility of the air and feeds the visibility signal back to the controller 4. Then, the controller 4 controls the electric push rod 201 to start. The output end of the electric push rod 201 can drive the fixed plate 202 and the arc-shaped protrusion 213 to move, so that the arc-shaped protrusion 213 moves away from the lamp beads 212 to a suitable position, until the light emitted by multiple lamp beads 212 is refracted into a highly focused state through the arc-shaped protrusion 213, so that the scattered light emitted by multiple lamp beads 212 is refracted into multiple focused beams, thereby improving the penetration ability of the car taillights in fog and making it easier for the car driver to see the signal lights.

[0034] Please refer to this carefully. Figure 3 and Figure 4A fixing shell 210 is fixed to the side of the second mounting plate 209 away from the transparent plate 203. A fixing rod 205 is fixed to the side of the fixing plate 202 away from the transparent plate 203. One end of the fixing rod 205 passes through the first mounting plate 208 and the second mounting plate 209 and extends into the interior of the fixing shell 210. Holes adapted to the fixing rod 205 are provided on both the second mounting plate 209 and the first mounting plate 208. A sliding plate 206 is fixed to the end of the fixing rod 205 inside the fixing shell 210. The outer surface of the sliding plate 206 is slidably connected to the inner wall of the fixing shell 210. Connecting pipes 204 are fixedly connected to both the upper and lower sides of the fixing shell 210. The end of the connecting pipe 204 away from the fixing shell 210 is fixedly connected to the transparent plate 203.

[0035] Simultaneously, the movement of the fixed plate 202 can drive the sliding plate 206 to move along the inner wall of the fixed shell 210 via the fixed rod 205, forming a pressure difference. At this time, the hydraulic medium 214 in the transparent plate 203 will enter the interior of the fixed shell 210 through the connecting pipe 204. Since the hydraulic medium 214 in the transparent plate 203 is drawn into the fixed shell 210, it will cause the transparent plate 203 to lose pressure, thereby causing the middle part of the transparent plate 203 to be concave, so that the transparent plate 203 and the hydraulic medium 214 inside it form a concave mirror, which increases the radiation angle of multiple focused beams, thereby improving the radiation range of multiple focused beams.

[0036] In use, this invention works as follows: During foggy weather, a fog sensor detects air visibility and feeds the visibility signal back to the controller 4. The controller 4 then activates the electric push rod 201. The output of the electric push rod 201 moves the fixed plate 202 and the arc-shaped protrusion 213, moving the arc-shaped protrusion 213 away from the LED beads 212 to a suitable position. This allows the light emitted by the multiple LED beads 212 to be refracted into a highly focused state by the arc-shaped protrusion 213, thus refracting the dispersed light emitted by the multiple LED beads 212 into multiple focused beams. This improves the penetration ability of the car taillights in fog, making it easier for the driver to see. Upon seeing the signal light, the movement of the fixed plate 202 can drive the sliding plate 206 to move along the inner wall of the fixed shell 210 via the fixed rod 205, creating a pressure difference. At this time, the hydraulic medium 214 in the transparent plate 203 will enter the interior of the fixed shell 210 through the connecting pipe 204. As the hydraulic medium 214 in the transparent plate 203 is drawn into the fixed shell 210, it will cause the transparent plate 203 to lose pressure, thereby causing the middle part of the transparent plate 203 to be concave. This makes the transparent plate 203 and the hydraulic medium 214 inside it form a concave mirror, which increases the radiation angle of multiple focused beams and thus improves the radiation range of multiple focused beams.
