Description

Technical Field

[0001] This utility model relates to a heat dissipation structure for LED lens headlights of scooter motorcycles. Background Technology

[0002] Scooter motorcycles are widely used due to their convenience and practicality. Their LED lens headlights provide clear and focused illumination at night or in dimly lit environments, significantly improving driving safety. However, in actual use, LED headlights generate a lot of heat during prolonged operation. Existing LED lens headlight heat dissipation designs are inadequate, making it difficult to dissipate heat quickly. This keeps the headlights at a high temperature, affecting the stability of light brightness, causing fluctuations in illumination, and accelerating the aging of LED chips and internal components, thus shortening the overall lifespan of the headlight. Therefore, existing technology needs further improvement and development. Summary of the Invention

[0003] To address the shortcomings mentioned above, this utility model provides a heat dissipation structure for LED lens headlights on scooter motorcycles.

[0004] To achieve the above objectives, this utility model provides a heat dissipation structure for an LED lens headlight for a scooter, including a lamp housing assembly. The lamp housing assembly includes a front cover frame and a lamp holder connected from front to back. The lamp holder has at least two mounting positions for LED lighting components. The lamp holder has a mounting hole I between adjacent mounting positions, and a locking member is limited and fitted within the mounting hole I. The front cover frame has a sleeve portion corresponding to the mounting hole I, and a connecting member is provided within the sleeve portion. The connecting member passes through the locking member and is threaded to it to fix the axial relative position of the front cover frame and the lamp holder. The connecting member has a mounting hole II, and a rotating shaft is rotatably and sealingly connected within the mounting hole II. Fan I and Fan II are respectively provided at both ends of the rotating shaft. When the vehicle is in motion, Fan I is driven to rotate forward by the oncoming airflow, thereby driving the rotating shaft and Fan II to rotate synchronously and achieve heat dissipation.

[0005] Furthermore, the locking member includes a base plate and two fastening parts symmetrically disposed at the rear end of the base plate for engaging with a mounting hole. The base plate has an internal threaded hole between the two fastening parts. One end of the connector has an external threaded section that engages with the internal threaded hole, and the other end has an abutment part that engages with the front cover frame.

[0006] Furthermore, the outer wall of the connector is provided with an annular mounting groove, and an abutment ring is provided on the annular mounting groove. The two ends of the abutment ring abut against the groove wall of the annular mounting groove and the rear wall of the sleeve, respectively, to limit the relative position of the front cover frame and the connector in the axial direction.

[0007] Furthermore, the rotating shaft is rotatably connected to the mounting hole 2 through multiple bearing components, and both ends are respectively provided with external thread section 2 and external thread section 3. Fan 1 and Fan 2 are respectively provided with connecting part 1 and connecting part 2. Connecting part 1 is provided with internal thread section 1 that mates with external thread section 2, and the tightening direction of the threads is opposite to the rotation direction of Fan 1. Connecting part 2 is provided with internal thread section 2 that mates with external thread section 3, and the tightening direction of the threads is opposite to the rotation direction of Fan 1.

[0008] Furthermore, a connecting threaded hole 1 communicating with the internal threaded section 1 is opened on one side wall of the connecting part, and a fixing screw 1 is threadedly connected to the connecting threaded hole 1. The bottom wall of the fixing screw 1 abuts against the external threaded section 2. A connecting threaded hole 2 communicating with the internal threaded section 2 is opened on the side wall of the connecting part 2, and a fixing screw 2 is threadedly connected to the connecting threaded hole 2. The bottom wall of the fixing screw 2 abuts against the external threaded section 3.

[0009] Furthermore, an annular mounting groove 2 is provided on the inner wall of the mounting hole 2, and multiple annular mounting grooves 3 are provided on the outer wall of the rotating shaft. The annular mounting groove 2 and the annular mounting groove 3 correspond one-to-one and are fitted with an annular sealing ring.

[0010] Furthermore, the front cover frame includes a cover ring that corresponds one-to-one with the corresponding LED lighting components. The inner wall of the cover ring is provided with at least one protrusion. The lamp housing assembly also includes multiple lamp shades. The lamp shades correspond one-to-one with the cover rings and are provided with a limiting ring on their outer wall that cooperates with the protrusion for limiting.

[0011] Furthermore, the lamp housing assembly also includes a rear cover located at the rear end of the lamp holder. The rear cover is connected to the front cover frame and the lamp holder by bolts and forms a communicating cavity with the atmosphere between the rear cover and the lamp holder.

[0012] The advantages of this utility model compared to the prior art are as follows: This utility model has a compact structure and does not require a complex electronic control system. Its core is to use the oncoming airflow generated when the vehicle is moving to drive the first fan to rotate in the forward direction, and to drive the second fan to rotate synchronously through the rotating shaft, so that a directional and continuous forced convection is formed behind the lamp holder, which significantly improves the airflow speed and flow rate of the heat-generating area at the rear of the LED lighting component, thereby greatly optimizing the heat dissipation efficiency and ensuring the stable and reliable operation of the LED lighting component.

Detailed Implementation

[0014] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides an LED lens headlight for a scooter, comprising a lamp housing assembly 100. The lamp housing assembly 100 includes a front cover frame 200 and a lamp holder 300 connected from front to back. The lamp holder 300 has mounting positions 301 for at least two LED lighting components. The lamp holder 300 has mounting holes 302 between adjacent mounting positions 301, and a locking member 1 is limited and engaged within the mounting holes 302. The front cover frame 200 has a sleeve portion 201 corresponding to the mounting holes 302, and a connecting member 2 is provided within the sleeve portion 201. The connecting member 2 passes through the locking member 1 and is threadedly connected to it. The front cover frame 200 and the lamp holder 300 are fixed in axial relative positions. The connector 2 is provided with a second mounting hole 21 and a rotating shaft 3 is rotatably and sealed within the second mounting hole 21. Fan 4 and fan 5 are respectively provided at both ends of the rotating shaft 3. When the vehicle is moving, the fan 4 is driven by the oncoming airflow and always rotates in the forward direction, thereby driving the rotating shaft 3 and fan 5 to rotate synchronously. This creates a directional and continuous forced convection behind the lamp holder 300, which significantly improves the airflow speed and flow rate in the heat-generating area at the rear of the LED lighting component, thereby greatly optimizing the heat dissipation efficiency, achieving heat dissipation and ensuring the stable and reliable operation of the LED lighting component.

[0015] Furthermore, such as Figures 1-5 As shown, the locking member 1 in this embodiment includes a base plate 11 and two fastening portions 12 symmetrically disposed at the rear end of the base plate 11 for engaging with mounting holes 302. The mounting holes 302 have a quadrilateral cross section. The two fastening portions 12 of the locking member 1 can be rigidly installed into the mounting holes 302 and their rotation is restricted by the mounting holes 302. The base plate 11 has an internal threaded hole 11-1 between the two fastening portions 12. One end of the connecting member 2 has an external threaded section 22 that engages with the internal threaded hole 11-1, and the other end has an abutment portion 23 that engages with the front cover frame 200. The outer side wall of the connecting member 2 is provided with... An annular mounting groove 24 is provided with an abutment ring 6. During installation, the connector 2 passes through the sleeve portion 201 and the abutment ring 6 is placed on the annular mounting groove 24. Then, the external thread section 22 of the connector 2 is threaded to the internal thread hole 11-1 of the base plate 11 until the abutment portion 23 abuts against the front wall of the abutment portion 23, fixing the relative axial position of the front cover frame 200 and the lamp holder 300. At the same time, both ends of the abutment ring 6 abut against the groove wall of the annular mounting groove 24 and the rear wall of the sleeve portion 201, respectively, to limit the relative axial position of the front cover frame 200 and the connector 2.

[0016] Furthermore, such as Figures 1-5As shown, in this embodiment, the rotating shaft 3 is rotatably connected to the mounting hole 21 through multiple bearing components 7, and both ends are respectively provided with external thread section 25 and external thread section 26. Fan 1 4 and Fan 2 5 are respectively provided with connecting part 1 41 and connecting part 2 51. Connecting part 1 41 is provided with internal thread section 1 41-1 that mates with external thread section 2 25, and the tightening direction of the threads is opposite to the rotation direction of fan 1 4. Connecting part 2 51 is provided with internal thread section 2 51-1 that mates with external thread section 3 26, and the tightening direction of the threads is opposite to the rotation direction of fan 1 4. This makes the threaded connection between fan 1 4 and fan 2 5 and rotating shaft 3 more secure, ensuring the stability and reliability of the heat dissipation structure.

[0017] Furthermore, such as Figures 1-5 As shown, in this embodiment, the connecting part 41 has a connecting threaded hole 41-2 on its side wall that communicates with the internal thread section 41-1. A fixing screw 8 is threaded onto the connecting threaded hole 41-2. The bottom wall of the fixing screw 8 abuts against the external thread section 25. The connecting part 51 has a connecting threaded hole 51-2 on its side wall that communicates with the internal thread section 51-1. A fixing screw 9 is threaded onto the connecting threaded hole 51-2. The bottom wall of the fixing screw 9 abuts against the external thread section 26. The setting of fixing screw 8 and fixing screw 9 effectively prevents the threads of fan 4 and fan 5 from loosening during long-term high-speed rotation, greatly improving the stability of the connection between fan 4 and fan 5 and the shaft 3, thereby ensuring the continuous and effective operation of the entire heat dissipation structure under the complex driving conditions of the motorcycle.

[0018] Furthermore, such as Figures 1-5 As shown, in this embodiment, an annular mounting groove 21-1 is provided on the inner wall of the mounting hole 21, and multiple annular mounting grooves 31 are provided on the outer wall of the rotating shaft 3. The annular mounting grooves 21-1 and 31 correspond one-to-one and are fitted with an annular sealing ring 10. The annular sealing ring 10 has good elasticity and sealing performance. When the rotating shaft 3 is installed into the mounting hole 21, the annular sealing ring 10 is compressed between the annular mounting grooves 21-1 and 31, which can effectively prevent dust, water vapor and mud splashed on the road from entering the lamp housing assembly 100 through the gap between the rotating shaft 3 and the mounting hole 21, avoiding contamination or corrosion of the internal components of the LED lighting assembly, thereby further improving the service life and reliability of the LED lighting assembly, especially suitable for the use of motorcycles in harsh environments such as rainy and foggy weather and muddy roads.

[0019] Furthermore, such as Figures 1-5As shown, the front cover frame 200 in this embodiment includes a cover ring 210 corresponding to each LED lighting component. The inner wall of the cover ring 210 is provided with at least one protrusion 211. The lamp housing assembly 100 also includes a plurality of lamp covers 400. Each lamp cover 400 corresponds to a cover ring 210 and has a limiting ring 401 on its outer wall that cooperates with the protrusion 211 for limiting. The outer diameter of the limiting ring 401 is slightly smaller than the inner diameter of the cover ring 210 so that the lamp cover 400 can be smoothly installed into the cover ring 210. The axial limiting effect of the protrusion 211 on the limiting ring 401 can effectively prevent the lamp cover 400 from falling out of the cover ring 210 due to vibration or bumps during motorcycle operation. In addition, a sealing strip can also be provided between the lamp cover 400 and the cover ring 210 to enhance the sealing performance.

[0020] Furthermore, such as Figures 1-5 As shown, the lamp housing assembly 100 in this embodiment also includes a rear cover 500 located at the rear end of the lamp holder 300. The rear cover 500 is connected to the front cover frame 200 and the lamp holder 300 by bolts and forms a communicating cavity 501 with the lamp holder 300. Heat dissipation holes are opened on the rear cover 500 corresponding to each LED lighting component. The communicating cavity 501 is connected to the atmosphere through the heat dissipation holes, and the heat dissipation holes are all inclined downwards to effectively prevent rainwater, dust and other impurities from entering the lamp housing assembly 100 through the heat dissipation holes, thereby avoiding damage to the internal components such as the LED lighting components.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
