Description

Technical Field

[0001] This utility model relates to the field of motorcycle headlight heat dissipation technology, and more specifically, to a headlight radiator mounting structure. Background Technology

[0002] In the existing technology field, the design of motorcycle headlights has always revolved around two core objectives: improving lighting efficiency and extending service life. To optimize the optical performance of the lamp cover and body, the lamp chip layout generally adopts a high-density integrated design, achieving long-distance illumination and uniform light spot distribution through a concentrated light source.

[0003] Currently, significant shortcomings have been exposed in the application scenarios of motorcycle headlights on the market: Because motorcycle headlights typically employ a sealed structure to prevent internal water accumulation and condensation, their heat dissipation path heavily relies on passive heat conduction. When the LED chips operate at high power for extended periods, the localized heat flux density generated by their dense arrangement increases dramatically. However, the restricted airflow within the sealed cavity leads to a heat buildup effect in specific areas on the inner surface of the lamp cover, such as directly above the LED chips or at the edge of the optical lens. This localized overheating not only accelerates the aging and deformation of the lamp cover material, but also causes a decrease in light transmittance and light distortion.

[0004] Thermal stress concentration can lead to the failure of the sealing structure between the lamp cover and the lamp body, thereby shortening the overall lifespan of the lamp. Although existing technologies include active heat dissipation solutions such as adding heat sink fins or heat pipes, these all compromise the lamp body's seal, fundamentally contradicting the core requirements of waterproofing and fog prevention for motorcycle headlights. Therefore, there is an urgent need for an innovative radiator mounting structure that balances sealing performance with efficient thermal management. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a headlight radiator mounting structure with a heat dissipation structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention is further configured as follows: including a lamp body, the headlight heat sink mounting structure further includes a heat dissipation unit; the heat dissipation unit is disposed on the side of the lamp holder; the heat dissipation unit includes a lamp cover and a heat dissipation part; the lamp cover is disposed on the inner side of the lamp body; the heat dissipation part has a pair and is disposed on the side of the lamp holder respectively, and the pair of heat dissipation parts are located on the top of the lamp cover; the top of each pair of heat dissipation parts is provided with multiple heat dissipation holes, and the multiple heat dissipation holes are all located above the top of the lamp cover.

[0007] By adopting the above technical solution, the problem of local heat accumulation in the lamp cover is solved, achieving a more uniform internal temperature for the entire headlight. This effectively avoids damage to the lamp beads and lamp cover caused by local overheating, extends the lifespan of the headlight, and ensures that it maintains a stable and good lighting effect during long-term sealed operation.

[0008] The present invention is further configured such that the top of each pair of heat dissipation parts is a stepped structure, and the step direction of the stepped structure increases sequentially from left to right.

[0009] The present invention is further configured such that: the stepped structure of the heat dissipation part is arranged along the top inclined direction of the lampshade, and the top inclined direction of the lampshade is gradually increased from left to right.

[0010] The present invention is further configured such that: the stepped surface of the top stepped structure of the heat dissipation part is divided into a first stepped surface, a second stepped surface and a third stepped surface in sequence, and the top width cross-sectional dimensions of the first stepped surface, the second stepped surface and the third stepped surface gradually increase.

[0011] The present invention is further configured such that multiple heat dissipation holes are located at the top of the three stepped platforms, and the diameter of the multiple heat dissipation holes is the same.

[0012] The present invention is further configured such that: the lower part of each pair of heat dissipation parts is a U-shaped connector extending to the bottom of the inner side of the lamp holder, the U-shaped connector is integrally connected with the heat dissipation part, and the end face of the U-shaped connector is provided with an installation positioning groove.

[0013] The present invention is further configured such that: the heat dissipation unit also includes a fastener; the fastener is located on the side of the U-shaped connector, and the fastener can secure the heat dissipation part and the lamp holder in a tight installation state by screwing in the thread.

[0014] By adopting the above technical solution, during installation, after the heat sink is initially positioned by the U-shaped connector, fasteners are screwed in to ensure a tight connection between the fasteners, the lamp holder, and the heat sink, further enhancing the connection strength between them. This allows the installed heat sink to withstand certain external forces, preventing it from loosening due to vehicle vibrations during operation. It ensures the heat sink remains stably fixed to the lamp holder, continuously performing its heat dissipation function and guaranteeing the long-term stable and reliable operation of the headlight radiator mounting structure.

This effectively prevents damage to the LED chips and lamp cover from localized overheating, extends the headlight's lifespan, and ensures stable and effective lighting even during prolonged sealed operation.

[0016] By using fasteners, after the heat sink is initially positioned using the U-shaped connector during installation, the fasteners are screwed in to ensure a tight connection between the fasteners, the lamp holder, and the heat sink, further enhancing the connection strength between them. This allows the installed heat sink to withstand certain external forces, preventing it from loosening due to vehicle vibrations during operation. It ensures the heat sink remains stably fixed to the lamp holder, continuously performing its heat dissipation function and guaranteeing the long-term stable and reliable operation of the headlight radiator mounting structure.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Please see Figure 1-5 The present invention provides the following technical solution: In the first embodiment, in the prior art, the lamp beads are generally arranged in this way to improve the lighting effect of the lamp cover 21 and the lamp body 1. However, in the case of motorcycle lamps, which are usually sealed structures and mainly used to prevent water accumulation and fogging inside the lamp, this arrangement will cause the lamp cover 21 to face the problem of local heat accumulation after long-term operation.

[0021] The headlight heat sink mounting structure includes a lamp body 1 and a heat dissipation unit 2. The heat dissipation unit 2 is located on the side of the lamp holder. The heat dissipation unit 2 includes a lamp cover 21 and a heat dissipation part 22. The lamp cover 21 is located on the inside of the lamp body 1. There is a pair of heat dissipation parts 22, which are respectively located on the side of the lamp holder, and the pair of heat dissipation parts 22 are located on the top of the lamp cover 21. The top of each pair of heat dissipation parts 22 is provided with a plurality of heat dissipation holes 2201, and the positions of the plurality of heat dissipation holes 2201 are all located above the top of the lamp cover 21.

[0022] In the headlight heat sink mounting structure of this embodiment, multiple sets of LED beads are arranged at the reflective position of the lamp cover 21, and these multiple sets of LED beads are all located at the top of the lamp cover 21 and below the heat sink 22. When the LED beads start working and generate heat, the heat is first transferred to the lamp cover 21. As the lamp cover 21 is continuously heated, heat will gradually accumulate in local areas. At this time, the heat will be further conducted to the heat sink 22 located at the top of the lamp cover 21. The top of the heat sink 22 has multiple heat dissipation holes 2201. During the operation of the LED beads, the heat sink 22 itself will increase in temperature due to absorbing heat, and the internal material of the heat sink 22 will expand due to heat, increasing the internal air pressure. The heated and expanded air will form a certain pressure difference inside the heat sink 22, causing the hot air to flow in the tiny channels and gaps inside the heat sink 22. At the same time, the heat sink 22 is preferably made of a thermally conductive material and has good thermal conductivity. When heat is conducted inside the heat sink 22, it will be evenly distributed in all parts of the heat sink 22. This reduces heat buildup on the top of the lamp cover 21 caused by the operation of the LED. The temperature inside the entire headlight becomes more uniform, effectively preventing damage to the LED and lamp cover 21 caused by localized overheating, extending the headlight's lifespan, and ensuring stable and good lighting performance during long-term sealed operation. This solves the problem of localized heat buildup in the lamp cover 21, achieving a more uniform temperature throughout the headlight, effectively preventing damage to the LED and lamp cover 21 caused by localized overheating, extending the headlight's lifespan, and ensuring stable and good lighting performance during long-term sealed operation.

[0023] See Figure 4 and Figure 5 The top of each pair of heat dissipation parts 22 is a stepped structure, and the step direction of the stepped structure increases from left to right.

[0024] The stepped structure of the heat dissipation section 22 increases its heat dissipation surface area. When heat is conducted to the heat dissipation section 22, the increased surface area allows the heat to be more dispersed and contact the surrounding air, accelerating the heat exchange rate. The progressively increasing stepped direction from left to right allows air to flow more smoothly through the heat dissipation section 22, forming a good airflow channel, further promoting heat dissipation and improving heat dissipation efficiency.

[0025] See Figure 4 and Figure 5 The stepped structure of the heat dissipation part 22 is arranged along the top inclined direction of the lamp cover 21, and the top inclined direction of the lamp cover 21 is gradually increased from left to right.

[0026] The stepped shape of the heat dissipation section 22 is arranged along the inclined direction of the top of the lamp cover 21, making the heat dissipation section 22 fit more closely with the top structure of the lamp cover 21, and making the process of heat conduction from the lamp cover 21 to the heat dissipation section 22 smoother. At the same time, the inclined direction of the top of the lamp cover 21 and the stepped structure of the heat dissipation section 22 are compatible with each other, which helps to guide the air to flow in a specific direction, forming an orderly airflow, enhancing the air convection effect, and enabling the heat dissipation section 22 to dissipate heat more efficiently, thereby improving the heat dissipation performance of the entire headlight radiator mounting structure.

[0027] See Figure 4 and Figure 5 The stepped surface of the top stepped structure of the heat dissipation part 22 is divided into a first step surface 221, a second step surface 222 and a third step surface 223, and the top width cross-sectional dimensions of the first step surface 221, the second step surface 222 and the third step surface 223 gradually increase.

[0028] Different widths of stepped surfaces allow heat to come into more thorough contact with the air in different areas. During heat conduction, the heat passes sequentially through the first stepped surface 221, the second stepped surface 222, and the third stepped surface 223. Due to the different widths of the first stepped surface 221, the second stepped surface 222, and the third stepped surface 223, the air can form different flow states when flowing through them, generating more turbulence, thereby enhancing the heat exchange effect, improving the heat dissipation capacity of the heat sink 22, and ensuring that the headlight temperature remains within a reasonable range during long-term operation.

[0029] See Figure 4 and Figure 5 Multiple heat dissipation holes 2201 are located at the top of the three stepped platforms, and the diameter of the multiple heat dissipation holes 2201 is the same.

[0030] The design of heat dissipation holes 2201 with the same diameter ensures that the airflow and velocity are relatively uniform when passing through the heat dissipation holes 2201, which is conducive to forming stable air convection and avoids the problem of poor airflow or uneven heat dissipation in some areas due to the different sizes of the heat dissipation holes 2201, thereby improving the heat dissipation uniformity and heat dissipation efficiency of the entire heat dissipation part 22.

[0031] See Figure 4 and Figure 5 Below each pair of heat dissipation parts 22 are U-shaped connectors extending to the bottom of the inner side of the lamp holder. The U-shaped connectors are integrally connected to the heat dissipation parts 22, and the end face of the U-shaped connectors is provided with a mounting and positioning groove.

[0032] The U-shaped connector extending to the bottom of the inner side of the lamp holder can fix the position of the heat dissipation part 22 on the lamp holder and prevent the heat dissipation part 22 from shifting due to vibration or other reasons during operation.

[0033] See Figure 4 and Figure 5 The heat dissipation unit 2 also includes a fastener 23; the fastener 23 is located on the side of the U-shaped connector, and the fastener 23 can secure the heat dissipation part 22 and the lamp holder by screwing in the thread.

[0034] During installation, after the heat sink 22 is initially positioned by the U-shaped connector, the fastener 23 is screwed in to ensure a tight connection between the fastener 23, the lamp holder, and the heat sink 22, further enhancing the connection strength between them. This allows the installed heat sink 22 to withstand certain external forces, preventing it from loosening due to vehicle vibrations during operation. This ensures the heat sink 22 remains stably fixed to the lamp holder, continuously performing its heat dissipation function and guaranteeing the long-term stable and reliable operation of the headlight radiator mounting structure.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
