For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The present application provides a vehicle lamp assembly, comprising: a vehicle lamp (not shown) and Figures 2 to 5The vehicle light control unit shown is connected to the vehicle light via the plug connector 215 of the plug interface 211. By using the above vehicle light control unit, the cost of the vehicle light assembly can be effectively reduced and the weight of the vehicle light assembly can be lightened.

[0044] The specific structure of the vehicle light control unit of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0045] refer to Figure 2 and Figure 3 The embodiment of the present application discloses a vehicle light control unit, including: an upper cover 21, a PCB board 22 and a sheet metal part 23.

[0046] Exemplarily, the edge of the upper cover 21 is provided with a plurality of fixing portions 213 for fixing the upper cover 21 to the vehicle body, wherein the upper cover 21 is made of plastic. Along the first direction X, the upper cover 21 and the sheet metal part 23 are covered to form a receiving space 210, and the PCB board 22 is fixed in the receiving space 210.

[0047] Continue to refer Figure 2 and Figure 3 Combined with Figure 1 Compared with the conventional headlight control unit, the present application replaces the die casting 13 with a sheet metal part 23. Compared with the die casting 13, the sheet metal part 23 is lighter and has a lower cost, thereby making the headlight control unit of the present application lighter and has a lower cost than the conventional headlight control unit.

[0048] In addition, during assembly, Figure 1 In the conventional vehicle light control unit shown in the figure, the PCB board 12 is first fixed to the die casting 13 by means of screws 121, and then the upper cover 11 is buckled to the die casting 13 by means of buckles 111 and protrusions 132 to complete the assembly. During the buckling process, the upper cover 11 is pressed downward toward the PCB board 12 along the first direction X, which may easily cause damage to the components on the PCB board 12.

[0049] refer to Figure 2 and Figure 3 Combined with Figure 4 and Figure 5 When assembling the headlight control unit of the embodiment of the present application, the PCB board 22 is first placed upside down on the upper cover 21. The inner wall of the upper cover 21 is provided with a plurality of ribs 216, and the plurality of ribs 216 are in contact with the edge of the PCB board 22. Then the sheet metal part 23 is fixed to the upper cover 21 by screws 24. Along the first direction X, the ribs 216 and the sheet metal part 23 jointly clamp the PCB board 22 to fix the PCB board 22. Compared with the traditional headlight control unit, the headlight control unit of the embodiment of the present application will not generate a downward pressure on the PCB board 22 during assembly, so it is not easy to damage the components on the PCB board 22, and the performance of the headlight control unit can be effectively guaranteed.

[0050] refer to Figure 4 and Figure 5 In some possible implementations, a plurality of abutment portions 233 are provided on the surface of the sheet metal part 23. Along the first direction X, the abutment portions 233 protrude toward the PCB board 22, and a depression is formed on the surface of the sheet metal part 23 facing away from the PCB board (such as Figure 5 The abutting portion 233 is used to abut the PCB board 22, so that the sheet metal component 23 can better support the PCB board 22, and at the same time, the PCB board 22 can be better grounded.

[0051] In the embodiment of the present application, the number of the fixing parts 213 is three, but is not limited thereto. For example, the number may be four, five, six or other multiple numbers.

[0052] For example, in the embodiment of the present application, the fixing portion 213 is a fixing hole. When the headlight control unit is assembled, the upper cover 21, the PCB board 22 and the sheet metal part 23 can be fixed to the vehicle body through the three fixing portions 213 and screws to achieve the installation of the headlight control unit.

[0053] In some possible implementations, reference Figures 3 to 5 The sheet metal part 23 is provided with a plurality of protrusions 231 on the surface facing away from the PCB board 22 along the first direction X. The interior of the protrusion 231 is hollow to form an avoidance space 230. The avoidance space 230 is connected to the accommodating space 210 along the first direction X. The avoidance space 230 can avoid the components on the PCB board 22 to avoid damaging the components on the PCB board 22.

[0054] It should be noted that the embodiment of the present application does not impose any specific restrictions on the shape and size of the protrusion 231, and the shape of each protrusion 231 is also different. The specific shape of the protrusion 231 can be adjusted according to the components on the PCB board 22. For example, when the component is large, the required avoidance space 230 is also large, and accordingly, the size of the protrusion 231 is also large. The shape of the protrusion 231 can be adjusted according to the specific shape of the component and the shape of the avoidance space 230 required by the component. For example, Figure 5 The shapes and sizes of the protrusions 231a, 231b and 231c are different.

[0055] The sheet metal part 23 of the embodiment of the present application can dissipate heat from the vehicle body control unit through heat conduction. At the same time, the outside air can form heat convection in the gaps 232 formed between the multiple protrusions 231 on the surface of the sheet metal part 23, further improving the heat dissipation effect of the sheet metal part 23. Specifically, when the car is driving, the outside air enters the headlights and then enters the gaps 232, forming heat convection in the gaps 232, taking away the heat of the vehicle body control unit, and improving the heat dissipation effect of the vehicle body control unit.

[0056] In some possible implementations, the surface of the sheet metal part 23 is plated with a black oxide film so that the sheet metal part 23 has a heat radiation function, further improving the heat dissipation effect of the vehicle body control unit.

[0057] In some possible implementations, reference Figures 2 to 4 The top of the upper cover 21 is provided with a plug interface 211, and the plug interface 211 is used for electrically connecting the PCB board 22 and external components (such as LED lights). Specifically, a plug connector 215 is provided in the plug interface 211, and the body control unit can be connected to an external component (such as an LED light) through the plug connector 215.

[0058] Exemplarily, along the first direction X, the edge of the plug interface 211 protrudes toward the side away from the accommodating space 210 to form a side wall 212, and a sealing ring 214 is provided on the outer cover of the side wall 212 to prevent water, moisture, etc. from entering the accommodating space 210 through the plug interface 211 and affecting the performance of the PCB board 22.

[0059] Exemplarily, in the embodiment of the present application, there are three sealing rings 214 , which are spaced apart on the side wall 212 along the first direction X, but the present invention is not limited thereto. In some possible implementations, there may be four, five, six or more sealing rings 214 .

[0060] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
