Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a detachable electric vehicle LED lamp module. Background Art

[0002] Electric vehicle lamps are primarily used as a source of illumination for nighttime illumination. With the advancement of technology, LED modules are often incorporated into headlights to enhance nighttime illumination. To protect LED lamps, the existing method involves installing a protective cover on the PCB. This outermost layer, a lampshade, protects the PCB. This method provides only one level of protection, and moisture entering the lampshade can easily contact the PCB, impacting its lifespan. Furthermore, replacing the PCB requires removing both the lampshade and protective cover, which is time-consuming and labor-intensive. Currently, LED headlights typically dissipate heat using three methods: radiator, braided belt, and fan. Therefore, there are higher demands on the thermal conductivity and heat dissipation structure of the lamp to better dissipate heat from the LED lamp module. Utility Model Content

A heat dissipation component for sealing the rear groove is removably provided at the rear end of the mounting base.

[0005] A further improvement includes providing a plurality of PCB boards.

[0006] Further improvements include that the heat dissipation assembly includes a connecting plate, several external heat dissipation plates and several internal heat dissipation plates, the external heat dissipation plates are evenly arranged at the rear end of the connecting plate, and the internal heat dissipation plates are evenly arranged at the front end of the connecting plate.

[0007] A further improvement includes embedding the connecting plate into a second groove formed on the rear end of the mounting seat.

[0008] A further improvement includes providing a front groove at the front end of the mounting seat for matching and loading the protective cover.

[0009] A further improvement includes providing a fixing piece on the mounting seat for fixing.

[0010] The beneficial effects of the utility model are as follows: the protective cover is installed on the mounting base, and the LED lamp beads on the PCB board are illuminated through the through holes, and then the protective cover and the PCB board are installed separately, so that the PCB board is doubly protected by the protective cover and the lampshade, ensuring lighting while preventing water vapor from contacting the PCB board, and the PCB board can be easily disassembled by simply removing the heat dissipation component, and the heat dissipation component quickly conducts the heat generated by the PCB board in the rear groove.

DETAILED DESCRIPTION

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0019] according to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a detachable electric vehicle LED lamp module includes a mounting base 3, a lampshade 2 and a heat dissipation component 9. A rear groove 5 is provided on the rear end of the mounting base 3. A PCB board 4 is detachably provided at the bottom of the rear groove 5. The LED lamp beads 11 provided on the PCB board 4 are embedded in the through-hole 6 provided on the mounting base 3. The LED lamp beads 11 emit light for lighting and illuminate the front end of the mounting base 3 through the through-hole 6. A protective cover 8 and a lampshade 2 are detachably provided at the front end of the mounting base 3 to cover the LED lamp beads 11. The lampshade 2 is provided on the outer layer of the protective cover 8. In order to provide outer protection for the protective cover 8 and the LED lamp beads 11, the protective cover 8 cooperates with the lampshade 2 to achieve double protection for the LED lamp beads 11, effectively blocking external rainwater from entering the lampshade 2. The protective cover 8 and the lampshade 2 are both made of transparent material, thereby ensuring that the light generated by the LED lamp beads 11 can pass through the protective cover 8 and the lampshade 2, thereby realizing the lighting function of the electric vehicle. The rear end of the mounting seat 3 is detachably provided with a heat dissipation component 9 for sealing the rear groove 5. The heat dissipation component 9 is used to dissipate the heat generated by the PCB board 4 in the rear groove 5 when it is working, thereby ensuring the normal operation of the PCB board 4.

[0020] In this embodiment, if Figure 2 and Figure 3 As shown, the PCB board 4 can be provided with multiple LED lamp beads 11 on multiple PCB boards 4, which can be turned on independently or simultaneously, thereby realizing the adjustment of the overall brightness of the electric vehicle headlights. When the LED lamp beads 11 corresponding to one of the PCB boards 4 fails to light up, the LED lamp beads 11 on other PCB boards 4 can be turned on. The PCB board 4 is easy to disassemble and install.

[0021] In this embodiment, if Figure 3 and Figure 5 As shown, the heat dissipation component 9 includes a connecting plate 92, several external heat dissipation plates 91 and several internal heat dissipation plates 93. The external heat dissipation plates 91 are evenly arranged at the rear end of the connecting plate 92, and the internal heat dissipation plates 93 are evenly arranged at the front end of the connecting plate 92. The internal heat dissipation plates 93 and the external heat dissipation plates 91 increase the heat absorption and heat dissipation area of the heat dissipation component 9, thereby improving the heat dissipation speed and ensuring the normal and stable operation of the PCB board 4.

[0022] In this embodiment, Figure 2 As shown, the connecting plate 92 is embedded in the second groove 10 opened on the rear end of the mounting seat 3. This design increases the sealing while improving the stability of the installation of the heat dissipation component 9, and prevents the vibration generated by the normal driving of the electric vehicle from loosening the installation of the heat dissipation component 9.

[0023] In this embodiment, in order to ensure the installation stability of the protective cover 8 and avoid the connection being loosened due to vibration, Figure 3 and Figure 4As shown, the front end of the mounting seat 3 is provided with a front groove 7 for matching and loading the protective cover 8 .

[0024] In this embodiment, in order to facilitate the fixing of the mounting base 3, as shown in FIG. Figure 1 As shown, the mounting seat 3 is provided with a fixing member 1 for fixing, that is, the fixing member 1 can be fixed to the front end of the electric vehicle by bolts.

[0025] Working principle: First, install the protective cover 8 in the front groove 7 to cover the through hole 6, then install the lampshade 2 at the front end of the mounting base 3, and the lampshade 2 covers the protective cover 8 inside, thereby performing secondary sealing protection; install the PCB board 4 in the rear groove 5, and the LED lamp beads 11 correspond to the through hole 6, and then install the heat dissipation component 9 at the port of the rear groove 5 to seal the rear groove 5, thereby protecting the PCB board 4.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
