Description

Technical Field

[0001] This utility model relates to the field of motorcycle lights, and in particular to a motorcycle light with a self-locking structure. Background Technology

[0002] Motorcycle lights typically consist of core components such as LED chips, heat sinks, and lamp housings. The way these components are connected and fixed directly affects the overall quality, ease of installation, and maintenance costs of the light. Currently, most motorcycle lights use bolts to fix the LED chips to the heat sink and the heat sink to the lamp housing. While bolt fixing can achieve the connection between components to a certain extent, it has the following problems:

[0003] During installation, using bolts for fixing requires specialized wrenches, screwdrivers, etc., making the operation relatively cumbersome and affecting installation efficiency. When it is necessary to repair or replace the LED beads or heat sink, all related bolts must be removed one by one, repaired or replaced, and then installed and tightened one by one. This process is also cumbersome and time-consuming. On the production line, tightening each bolt takes a certain amount of time, which not only increases the production cycle but also increases production costs.

[0004] Therefore, this utility model provides a motorcycle headlight with a self-locking structure to meet the requirements. Utility Model Content

By setting a self-locking component, the installation process is simplified, the installation and maintenance efficiency is improved, the production cycle is effectively shortened, and the production cost is reduced. The above settings can solve the problem of cumbersome operation process caused by installing and removing bolts one by one, which leads to increased production cycle and increased production cost.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A motorcycle headlight with a self-locking structure includes a headlight housing, a lamp shade snapped onto the top of the headlight housing, a heat sink fixed inside the headlight housing, a fixing plate fixed to the top of the heat sink, and an LED bead fixed to the top of the fixing plate; and a self-locking assembly for simultaneously fixing the LED bead and the heat sink, the self-locking assembly being connected to both the headlight housing and the fixing plate.

[0008] Optionally, the self-locking assembly includes a pressure plate, a pin, and a latch. The pressure plates are symmetrically arranged on the top of the heat sink. One pressure plate can slide on the top of the heat sink. The sides of the two pressure plates that are close to each other are respectively inserted into the two sides of the fixing plate. The latch is circumferentially fixed to the bottom of the pin surface. One end of the pin passes through the heat sink, the pressure plate, and the lamp housing. When the bottom end of the pin passes through the bottom of the lamp housing, the latch engages with the bottom of the lamp housing.

[0009] Optionally, one of the pressure plates has a through opening at its top, through which the pin passes and the through opening can slide horizontally on the surface of the pin; the other pressure plate has a through hole at its top, through which the pin passes.

[0010] Optionally, a limiting groove is provided inside the through-hole, and multiple pins are provided. A limiting strip is fixed to the surface of the pin that passes through the through-hole, and the limiting groove and the limiting strip are inserted into each other.

[0011] Optionally, each pressure plate has a pressure groove on its inner side, and the inner walls of the two pressure grooves abut against the outer walls of the fixing plate on both sides.

[0012] Optionally, sliders are fixed on both sides of the inner wall of the pressure groove, and sliding grooves are opened on both sides of the fixing plate, with the sliders and sliding grooves being inserted into each other.

[0013] Optionally, when the pressure plate slides to the side wall of the pin and the through-hole near the fixed plate, the slider cancels its engagement with the slide groove.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting a self-locking component, the LED beads and heat sink are fixed at the same time, as are the heat sink and the lamp housing. There is no need to use additional tools to tighten the bolts, and there is no need to perform cumbersome bolt disassembly and installation operations. This effectively simplifies the installation process, thereby improving installation and maintenance efficiency, and thus effectively shortening the production cycle and reducing production costs.

[0019] By using pressure plates, pins, and latches, the installation process eliminates the need for complex tools and cumbersome steps, shortening installation time.

[0035] like Figures 1 to 8As shown, an embodiment of this utility model provides a motorcycle lamp with a self-locking structure, including a lamp housing 1. A lamp cover 2 is snapped onto the top of the lamp housing 1. A sealing strip is provided between the lamp housing 1 and the lamp cover 2, which can ensure both a stable connection and a tight seal between the two, thereby improving the sealing performance of the lamp. A heat sink 5 is fixed inside the lamp housing 1. A fixing plate 4 is fixed to the top of the heat sink 5. An LED 3 is fixed to the top of the fixing plate 4. The LED 3 is embedded in the fixing plate 4. The heat sink 5 is directly connected to the LED 3 through the fixing plate 4, so that the heat generated by the LED 3 can be quickly transferred to the heat sink 5 through the fixing plate 4. The heat sink 5 can be made of aluminum alloy. Multiple heat dissipation fins are evenly spaced at the bottom of the heat sink 5, which can... Increasing the contact area with air accelerates heat dissipation, effectively reducing the operating temperature of the LED bead 3 and ensuring its stable operation. The self-locking assembly simultaneously secures the LED bead 3 and the heat sink 5. Connected to both the lamp housing 1 and the mounting plate 4, the self-locking assembly eliminates the need for additional tools to tighten bolts during installation. For maintenance or replacement, simply release the self-locking assembly to remove the LED bead 3 and heat sink 5. After maintenance or replacement, the self-locking assembly allows for quick re-secured installation, eliminating the need for cumbersome bolt disassembly and installation. This simplifies the installation process, improves installation and maintenance efficiency, shortens the production cycle, and reduces production costs.

[0036] As one implementation method in this embodiment, such as Figures 2 to 6 As shown, the self-locking assembly includes a pressure plate 6, a pin 14, and a latch 15. The pressure plates 6 are symmetrically arranged on the top of the heat sink 5. One pressure plate 6 has a through-hole 11 at its top, through which the pin 14 passes. The through-hole 11 can slide horizontally on the surface of the pin 14, thus allowing one pressure plate 6 to slide on the top of the heat sink 5. The other pressure plate 6 has a through-hole 13 at its top, through which the pin 14 passes. The sides of the two pressure plates 6 that are close to each other are respectively inserted into the sides of the fixing plate 4. The latch 15 is circumferentially fixed to the bottom surface of the pin 14. One end of the pin 14 passes through the heat sink 5, the pressure plate 6, and the lamp housing 1. When the bottom end of the pin 14 passes through the bottom of the lamp housing 1, the latch 15 engages with the bottom of the lamp housing 1. During installation, simply insert the two pressure plates 6 into the two sides of the fixing plate 4 respectively, and then pass the pin 14 through the heat sink 5, pressure plate 6 and lamp housing 1 in sequence. When the bottom end of the pin 14 penetrates the bottom of the lamp housing 1, the latch 15 automatically engages with the bottom of the lamp housing 1 to complete the self-locking fixation. The entire installation process does not require complicated tools or cumbersome steps, shortening the installation time. When it is necessary to maintain or replace the components of the vehicle light, simply release the latch 15 from the bottom of the lamp housing 1 and pull out the pin 14 to easily remove the pressure plate 6, heat sink 5 and lamp beads 3 on the fixing plate 4. This allows maintenance personnel to quickly and conveniently inspect, repair and replace the internal components of the vehicle light, reducing maintenance difficulty and cost.

[0037] In this embodiment, as Figure 4 and Figures 7 to 8 As shown, the lamp housing 1 has a mounting hole 10 at the bottom. When the pin 14 and the latch 15 pass through the mounting hole 10, the latch 15 engages with the bottom of the lamp housing 1, which realizes the quick self-locking fixation of the lamp bead 3 and the heat sink 5 to the lamp housing 1. No additional tools or complicated operations are required, which improves the installation efficiency. At the same time, when disassembly is required, simply release the latch 15 from the bottom of the mounting hole 10 to easily remove the pin 14 and release the self-locking, which is convenient for maintenance and replacement.

[0038] In this embodiment, as Figure 4 and Figure 7 As shown, the outer and inner walls of the latch 15 are both arc-shaped, which makes the latch 15 easier to insert into the mounting hole 10 and snap into the bottom of the lamp housing 1. The arc-shaped surface can reduce the resistance during the insertion process, reduce the difficulty of operation, and improve the installation efficiency. At the same time, when snapping in place, the arc-shaped structure can better fit into the bottom of the lamp housing 1, enhancing the firmness of the snapping.

[0039] In this embodiment, as Figure 3 and Figure 5 As shown, a limiting groove 12 is provided inside the through-hole 11, and multiple pins 14 are provided. A limiting strip 18 is fixed on the surface of the pin 14 that passes through the through-hole 11. The limiting groove 12 and the limiting strip 18 are inserted and engaged, which can effectively limit the position of the pressure plate 6, thereby ensuring that the insertion and engagement between the pressure plate 6 and the fixing plate 4 is stable and reliable, and thus maintaining the connection stability of the fixing plate 4 and the lamp beads 3 fixed on it.

[0040] In this embodiment, as Figure 3 and Figures 5 to 6 As shown, the inner side of the pressure plate 6 is provided with pressure grooves 7. The inner walls of the two pressure grooves 7 abut against the outer walls of the fixing plate 4 on both sides. The pressure grooves 7 increase the contact area between the pressure plate 6 and the fixing plate 4, thereby increasing the friction and fixing force, so that the pressure plate 6 can better clamp the fixing plate 4, ensuring the stability of the installation position of the fixing plate 4 and the lamp beads 3 on it, and thus ensuring the optical performance of the entire vehicle lamp.

[0041] In this embodiment, as Figure 3 and Figures 5 to 6As shown, sliders 8 are fixed on both sides of the inner wall of the pressure groove 7, and sliding grooves 9 are provided on both sides of the fixing plate 4. The sliders 8 and sliding grooves 9 are engaged. When the pressure plate 6 slides to the side wall of the pin 14 and the through 11 near the fixing plate 4, the sliders 8 are no longer engaged with the sliding grooves 9. The engagement of the sliders 8 and sliding grooves 9 can effectively assist in positioning and guiding the installation of the pressure plate 6, allowing the operator to easily slide the pressure plate 6 along the sliding grooves 9 to the position where the inner wall of the pressure groove 7 abuts against the side wall of the fixing plate 4, thereby improving the convenience and accuracy of installation. At the same time, the engagement of the sliders 8 and sliding grooves 9 further enhances the connection stability between the pressure plate 6 and the fixing plate 4, which is beneficial to maintaining the structure of the vehicle headlight. For overall stability, when the pressure plate 6 slides to the side wall of the pin 14 and the through 11 near the fixed plate 4, the slider 8 cancels its engagement with the slide groove 9, allowing the pressure plate 6 on one side to release its restriction on the fixed plate 4. This allows the fixed plate 4 and the LED beads 3 on it to be quickly removed from one side. After maintenance, the new fixed plate 4 and LED beads 3 are aligned with the slider 8 on the fixed pressure plate 6 on one side and slid into the slide groove 9 until the side of the new fixed plate 4 abuts against the side wall of the pressure groove 7 in the fixed pressure plate 6. Then, the other pressure plate 6 is slid in the same way until it abuts against the other side of the fixed plate 4 to complete the installation. The entire process does not require disassembling all the self-locking components mentioned above, further simplifying the operation steps and saving maintenance time.

[0042] In this embodiment, as Figures 7 to 8 As shown, a connecting block 16 is fixed to the bottom of the heat sink 5, and a bolt 17 is fixed to the bottom of the lamp housing 1. The top of the bolt 17 passes through the lamp housing 1 and is threadedly connected to the connecting block 16. Together with the pin 14 and the latch 15, they form a double fixation for the heat sink 5, which further enhances the connection strength between the heat sink 5 and the lamp housing 1, improves the overall stability of the vehicle lamp structure, and ensures that the heat sink 5 can be firmly installed in the lamp housing 1 to effectively perform its heat dissipation function. When it is necessary to replace the heat sink 5, simply loosen the bolt 17 and release the self-locking mechanism with the latch 15 to easily remove the heat sink 5, which improves the convenience of maintenance.

[0043] The working principle of the technical solution provided by this utility model is as follows:

[0044] In use, the pressure plate 6 with the through hole 13 is placed on top of the heat sink 5, and the pin 14 passes through both the pressure plate 6 and the heat sink 5 to initially position and fix the pressure plate 6. One side of the fixing plate 4 with the LED bead 3 is aligned with the slider 8 on the initially positioned and fixed pressure plate 6, allowing it to slide within the grooves 9 on both sides of the fixing plate 4 until one side of the fixing plate 4 abuts against the side wall of the groove 7 in the initially positioned and fixed pressure plate 6. Then, the pressure plate 6 with the through opening 11 on the other side is slid in the same manner until it abuts against the other side of the fixing plate 4. The pin 14 with the limiting strip 18 is passed through the pressure plate 6 with the through opening 11 and the other side of the heat sink 5, and the limiting strip 18 is inserted into the limiting groove 12 in the through opening 11 to engage with the pressure plate 6 with the through opening 11. The position is effectively limited, which ensures the stable connection between the pressure plate 6 and the fixing plate 4. Then, the bottom end of the pin 14 corresponds to the mounting hole 10 in the lamp housing 1. Press the top end of the pin 14 in sequence. Under the guiding effect of the arc of its outer wall and the weakening effect of the arc of its inner wall, the latch 15 can be smoothly deformed and pass through the mounting hole 10 and then reset, thereby achieving self-locking fixation with the bottom of the lamp housing 1. This achieves simultaneous fixation of the lamp bead 3 and the heat sink 5 to the lamp housing 1. Then, tighten the bolt 17 to double fix the heat sink 5, further enhancing the connection strength between the heat sink 5 and the lamp housing 1. Finally, plug and fix the lamp housing 1 and the lamp cover 2 to complete the assembly of the vehicle light. After connecting the corresponding wiring, the vehicle light can be fixed on the motorcycle's vehicle light mounting bracket.

[0045] When it is necessary to replace or maintain the LED bead 3, open the lamp cover 2, push the latch 15 at the bottom of the pin 14 that fixes the limiting strip 18 inward. The latch 15 deforms smoothly under the guiding action of its outer arc and the weakening action of its inner arc, and then passes through the mounting hole 10. Pull the corresponding pin 14 upward until the limiting strip 18 is disengaged from the limiting groove 12. At this time, slide the pressure plate 6 with the opening 11 to the side wall of the pin 14 near the fixed plate 4, and cancel the engagement between the slider 8 and the slide groove 9, so that the pressure plate 6 on one side is released from the fixed plate 4. The limit position allows the fixing plate 4 and the lamp beads 3 on it to be quickly removed from one side. After maintenance, the new fixing plate 4 and the lamp beads 3 are aligned with the slider 8 on the pressure plate 6 with the through hole 13 and slid into the groove 9 until one side of the new fixing plate 4 abuts against the side wall of the pressure groove 7 in the pressure plate 6 with the through hole 13. Then, the other side pressure plate 6 is slid in the same way until it abuts against the other side of the fixing plate 4 to complete the fixing of the lamp beads 3. After that, the self-locking action of the pin 14 and the latch 15 is repeated and the lamp cover 2 and the lamp housing 1 are reconnected to complete the maintenance and replacement of the lamp beads 3.

[0046] When it is necessary to replace or maintain the heat sink 5, open the lamp cover 2, push the multiple latches 15 inward in sequence, pull out the pin 14, and then unscrew the bolt 17 to release the threaded connection with the connecting block 16. This will release the heat sink 5 from the lamp housing 1 and the lamp bead 3. After replacing the heat sink 5, repeat the above assembly steps to complete the maintenance and replacement of the heat sink 5.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
