Description

Technical Field

[0001] This utility model relates to a high and low beam headlight heat sink with a positioning structure, specifically a high and low beam headlight heat sink with a positioning structure, belonging to the technical field of heat dissipation devices. Background Technology

[0002] A headlight heatsink is a device installed inside or outside a headlight to dissipate the heat generated during operation. It is typically made of metal (such as aluminum alloy) and utilizes methods such as increasing the heat dissipation area (like finned structures), airflow (air cooling), or specific heat dissipation channel design to quickly remove heat generated by light sources like LEDs. This prevents overheating from causing light decay, shortening lifespan, or circuit failure, ensuring stable illumination in nighttime and rainy conditions. It is a crucial component for improving the reliability and lifespan of headlights.

[0003] The prior art patent application (application number 202122857498.1) entitled "Automotive Lighting Radiator" includes a heat dissipation base plate. The surface of the base plate is provided with several rows of parallel heat dissipation fins. A heat dissipation channel is reserved between each row of fins. The fins are arranged sequentially to form several rows of heat dissipation fins, with a second heat dissipation channel reserved between each row. The cross-section of the heat dissipation fins is wavy. Compared with the prior art, this utility model's automotive lighting radiator evenly distributes heat dissipation fins on the base plate, and the heat dissipation channels between the fins improve heat dissipation efficiency.

[0004] However, due to the lack of a quick-installation positioning structure, installation requires repeated adjustments to the position and alignment of screw holes, consuming a significant amount of time and effort. This not only affects production efficiency but also creates difficulties for later maintenance and replacement, limiting its convenience and efficiency in the automotive headlight assembly process. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to provide a high and low beam headlight radiator with a positioning structure to solve the above-mentioned problems. This solves the problem that the existing technology lacks a quick installation positioning structure, which requires repeated adjustments to the position and alignment of screw holes during installation, consuming a lot of time and effort, affecting production efficiency, and making later maintenance and replacement difficult, thus limiting its convenience and efficiency in the headlight assembly process.

[0006] This utility model is achieved through the following technical solution: a high and low beam vehicle headlight radiator with a positioning structure.

[0007] The device includes a mounting bracket, with a connecting seat slidably connected to the inner side of the mounting bracket. A fixing plate is fixedly connected at the middle between the top and bottom of the inner cavity of the connecting seat. Three limiting rods are fixedly connected to both sides of the fixing plate, and a compression spring is sleeved on the outer side of each limiting rod.

[0008] Preferably, a locking block is slidably connected between the outer sides of the three limiting rods. One side of the locking block passes through the connecting seat and the mounting bracket and extends to the outer side of the mounting bracket. The sliding cooperation between the locking block and the limiting rod allows the locking block to quickly extend and engage with the corresponding slot during installation, thereby achieving rapid positioning and fixing of the mounting bracket and the connecting seat. This effectively solves the problem of inconvenient installation of traditional vehicle headlight radiators and improves installation efficiency.

[0009] Preferably, a lever is fixedly connected to one side of the locking block, and one side of the lever extends to the outside of the connecting seat. The lever is designed to facilitate manual control of the extension and retraction of the locking block by the operator. During installation, the locking block is extended and locked by moving the lever. During disassembly, the locking state can be easily released by moving the lever in the opposite direction. This greatly facilitates the installation and disassembly operations and improves the ease of use.

[0010] Preferably, mounting plates are fixedly connected to both sides of the connecting seat, and a mounting cylinder is fixedly connected to one side of the mounting plate. An inclined insert is slidably connected to the inner cavity of the mounting cylinder. The combination of the mounting plate, mounting cylinder, and inclined insert provides an additional fixing method for the vehicle headlight radiator to the mounting location. During sliding, the inclined insert can be quickly inserted into the mounting hole using its inclined structure, further enhancing the stability of the connection and preventing the radiator from loosening during use.

[0011] Preferably, one end of the inclined stake passes through the locking block and extends into the interior of the locking block, and the other end of the inclined stake is fixedly connected to a connecting rod. A compression spring is sleeved on the outside of the connecting rod. The inclined stake and the locking block cooperate so that after the locking block is tightened, the inclined stake is further inserted into the interior of the locking block, achieving double fixation and improving the connection strength. The compression spring provides continuous pressure to the inclined stake, ensuring its stable insertion and enhancing the reliability of the overall structure.

[0012] Preferably, one end of the connecting rod passes through the mounting cylinder and extends to the outside of the mounting cylinder, and a connecting plate is fixedly connected to one end of the connecting rod. The connecting plate allows the operator to control the extension and retraction of the inclined stake by pulling or pushing the connecting plate. The operation is simple and intuitive, and it is easy to install and disassemble. At the same time, the connecting plate can also limit the pressure spring to ensure that the spring works normally.

[0013] Preferably, a heat dissipation base plate is fixedly connected to the top of the connector, and heat dissipation fins are fixedly connected to one side of the heat dissipation base plate. The heat dissipation fins are evenly distributed in sequence. A through hole is opened on one side of the heat dissipation base plate, and the through hole is evenly distributed. Two positioning posts are fixedly connected to one side of the heat dissipation base plate. The heat dissipation base plate and the evenly distributed heat dissipation fins increase the heat dissipation area, effectively improve the heat dissipation efficiency, and ensure the normal operation of the vehicle lights. The through hole facilitates air circulation and further enhances the heat dissipation effect. The presence of the positioning posts allows them to cooperate with the positioning holes of the installation part when installing the radiator, achieving fast and accurate positioning and further improving installation efficiency and accuracy.

[0014] Preferably, the thickness of the heat dissipation substrate is 3.5mm to 5mm, and the heat sinks on the heat dissipation substrate are divided into "S" shape and "dumbbell" shape. The rounded corners at the ends of the "S" shape are 0.15mm to 0.3mm, and the rounded corners at the ends of the "dumbbell" shape are 0.9mm to 1.2mm. The thickness of the middle area is 0.9mm to 1.3mm. The longitudinal dimension of a small section of the heat sink is 5mm to 15mm. The lateral gap between the heat sinks is 4mm to 6mm, the longitudinal gap is 3mm to 4mm, and the height of the positioning post is 1.6mm to 3mm.

[0015] This utility model provides a high and low beam headlight radiator with a positioning structure, which has the following beneficial effects:

[0016] 1. This high and low beam headlight radiator with a positioning structure can significantly improve installation efficiency through a quick installation mechanism. During installation, operators do not need to repeatedly align screw holes and adjust positions. The quick installation mechanism can quickly position and initially fix the radiator and headlight components, greatly shortening installation time, reducing labor costs, enhancing installation convenience, simplifying the installation process, and reducing installation difficulty.

[0017] 2. The high and low beam headlight radiator with positioning structure uses a locking mechanism to tightly engage the radiator with the headlight mounting position, providing strong locking force to prevent the radiator from loosening or shifting due to vibration, bumps, or other factors during vehicle operation, thus effectively improving the reliability of radiator installation.

[0018] 3. The high and low beam headlight heat sink with positioning structure has significant advantages in design and performance through its heat dissipation mechanism. In terms of heat dissipation performance, by reasonably designing the thickness of the heat dissipation substrate and the size of the heat flow channel, it can quickly remove the heat generated by the LED. Combined with the "S"-shaped heat sink to increase the heat dissipation area, it can effectively reduce headlight decay and improve the lifespan and lighting stability of the headlight.

[0028] This utility model embodiment provides a high and low beam vehicle headlight radiator with a positioning structure.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a mounting bracket 1, a connecting seat 2 that is slidably connected to the inner side of the mounting bracket 1, a fixing plate 201 that is fixedly connected at the middle between the top and bottom of the inner cavity of the connecting seat 2, three limiting rods 202 that are fixedly connected to both sides of the fixing plate 201, and a compression spring 203 that is sleeved on the outer side of the limiting rods 202.

[0030] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A locking block 204 is slidably connected between the outer sides of the three limiting rods 202. One side of the locking block 204 passes through the connecting seat 2 and the mounting bracket 1 and extends to the outer side of the mounting bracket 1. A lever 205 is fixedly connected to one side of the locking block 204. One side of the lever 205 extends to the outer side of the connecting seat 2.

[0031] During installation, align the connecting seat 2 with the installation position of the mounting bracket 1. Utilizing the sliding connection between the connecting seat 2 and the mounting bracket 1, the connecting seat 2 can quickly slide into the inner side of the mounting bracket 1. During the sliding process, the lever 205 is moved to cause the lever 205 to drive the locking block 204 to compress the compression spring 203, so that the compression spring 203 sleeved on the outside of the limiting rod 202 is in a compressed state. When the connecting seat 2 slides to the predetermined position, the slot pre-set on the mounting bracket 1 aligns with the locking block 204. At this time, under the action of the elastic restoring force of the compression spring 203, the locking block 204 is pushed to slide along the limiting rod 202. The locking block 204 quickly extends and locks into the slot of the mounting bracket 1, realizing the initial rapid positioning and fixation of the connecting seat 2 and the mounting bracket 1.

[0032] Please refer to it again. Figure 1 ,and Figure 4 Mounting plates 3 are fixedly connected to both sides of the connecting base 2. Mounting cylinder 301 is fixedly connected to one side of the mounting plate 3. Inclined insert 302 is slidably connected to the inner cavity of the mounting cylinder 301. One end of the inclined insert 302 passes through the locking block 204 and extends into the interior of the locking block 204. The other end of the inclined insert 302 is fixedly connected to the connecting rod 303. A pressure spring 304 is sleeved on the outside of the connecting rod 303. One end of the connecting rod 303 passes through the mounting cylinder 301 and extends to the outside of the mounting cylinder 301. A connecting plate 305 is fixedly connected to one end of the connecting rod 303. A heat dissipation base plate 4 is fixedly connected to the top of the connecting base 2. Heat dissipation fins 401 are fixedly connected to one side of the heat dissipation base plate 4. The heat dissipation fins 401 are evenly distributed in sequence. A through hole 402 is opened on one side of the heat dissipation base plate 4. The through holes 402 are evenly distributed. Two positioning posts 403 are fixedly connected to one side of the heat dissipation base plate 4.

[0033] After the locking block 204 moves out of the outer side of the connecting seat 2, the inclined insert 302 in the mounting cylinder 301 on the mounting plates 3 on both sides of the connecting seat 2, under the action of the pressure spring 304, the inclined surface of the inclined insert 302 contacts the inclined surface of the locking block 204. The inclined insert 302, using the inclined surface structure, quickly slides into the locking hole of the locking block 204 under pressure, locking the locking block 204, further enhancing the stability of the connecting seat 2 installation, thereby completing the quick installation process of the connecting seat 2.

[0034] This heat sink boasts significant advantages in design and performance. In terms of heat dissipation, the optimized design of the heat sink substrate thickness and heat flow channel dimensions allows for rapid removal of heat generated by the LEDs. Combined with an "S"-shaped heat sink to increase the heat dissipation area, it effectively reduces headlight decay, extends headlight lifespan, and improves lighting stability. Structurally, its lightweight design meets lightweight design requirements, reducing the overall weight of the lamp and facilitating vibration testing, ensuring product reliability in complex environments. During processing and assembly, the heat sink's front surface undergoes a secondary processing step, ensuring excellent flatness, significantly eliminating part dimensional errors, and eliminating draft angles on the front positioning posts, enabling precise assembly with the lamp panel. The through-hole design further optimizes the screw-on process for other parts, improving assembly efficiency. Furthermore, the "dumbbell"-shaped heat sink can carry QR code information from the high and low beam modules, facilitating rapid batch traceability of parts during production and use, improving product quality control, and comprehensively enhancing product competitiveness.

[0035] Working principle: During installation, align the connecting seat 2 with the installation position of the mounting bracket 1. Utilizing the sliding connection between the connecting seat 2 and the mounting bracket 1, the connecting seat 2 can quickly slide into the inner side of the mounting bracket 1. During the sliding process, the lever 205 is moved, causing the lever 205 to drive the locking block 204 to compress the compression spring 203. This compresses the compression spring 203, which is sleeved on the outside of the limiting rod 202. When the connecting seat 2 slides to the predetermined position, the slot pre-set on the mounting bracket 1 aligns with the locking block 204. At this time, under the elastic restoring force of the compression spring 203, the locking block 204 is pushed to slide along the limiting rod 202. When the connecting block 204 moves, it quickly extends and engages with the slot of the mounting bracket 1, achieving initial rapid positioning and fixation of the connecting seat 2 and the mounting bracket 1. After the connecting block 204 moves out of the outside of the connecting seat 2, the inclined inserts 302 in the mounting cylinders 301 on both sides of the mounting plate 3 of the connecting seat 2, under the action of the pressure spring 304, contact the inclined surface of the inclined inserts 302 with the inclined surface of the connecting block 204. The inclined inserts 302 utilize the inclined surface structure to quickly slide into the locking hole of the connecting block 204 under pressure, locking the connecting block 204 and further enhancing the stability of the connecting seat 2 installation, thereby completing the rapid installation process of the connecting seat 2.
