[0034] Figure 3 is the structural schematic diagram of the circuit board of the automotive headlamp combination lamp assembly for heavy-duty trucks with daytime running lamp function provided by the embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The technical solutions of the present application will be clearly and completely described below in conjunction with specific implementation schemes. However, those skilled in the art should understand that the implementation schemes described below are only used to illustrate the present application and should not be regarded as limiting the scope of the present application. Based on the implementation schemes in the present application, all other implementation schemes obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0036] As Figure 1-2 shown, an automotive headlamp combination lamp assembly for heavy-duty trucks with daytime running lamp function provided by the embodiment of the present application includes: a headlamp body 1 and a daytime running lamp 2, and the daytime running lamp 2 is integrated on the headlamp body 1;

[0037] Among them, the daytime running light 2 includes an LED lamp 21 for providing a light source, a reflector 22 for converging the LED light, and a circuit board 23 for providing a stable current. The reflector 22 is provided with a concave surface, the LED lamp 21 is arranged in the concave surface of the reflector 22, and the power connection end of the LED lamp 21 passes through the concave surface of the reflector 22 to connect to the circuit board 23.

[0038] Obviously, without adding extra lamps, by integrating the daytime running light 2 on the basis of the traditional heavy truck headlamp body 1, the vehicle headlamp combination lamp assembly is obtained, so that when driving during the day, the vehicle headlamp combination lamp assembly provides obvious identification signals to other vehicles running on the road, thereby enabling other vehicle drivers to effectively identify the vehicle position, reducing the probability of traffic accidents during daytime driving, and effectively improving the vehicle safety.

[0039] Meanwhile, due to the provision of the reflector 22, the light of the LED lamp 21 can be converged, thereby effectively enhancing the intensity of the identification signal of the daytime running light 2.

[0040] In addition, due to the provision of the circuit board 23, the current can be ensured to be stable, thereby ensuring the normal operation of the daytime running light 2.

[0041] In the embodiment of the present application, as Figure 1 shown, the headlamp body 1 includes a housing 11, a rear cover 12 and original lamps.

[0042] The housing 11 and the rear cover 12 are snap-connected to form an accommodation space. The daytime running light 2 is arranged on the upper side edge of the accommodation space, and the original lamps are arranged in the remaining space of the accommodation space.

[0043] Among them, the upper side edge of the accommodation space can be the upper left side or the upper right side, which is a position convenient for other vehicle drivers to identify.

[0044] In addition, the original lamps include a turn signal lamp 13, a high beam lamp 14, a low beam lamp 15, a width indicator lamp 16, etc., which are not limited herein.

[0045] Obviously, in the embodiment of the present application, without changing the main structure of the original headlamp, the daytime running light 2 is integrated, which not only saves the costs such as mold development, but also greatly reduces the development cost, that is, with minimal cost investment, the development of the headlamp combination lamp with the function of the daytime running light 2 is realized.

[0046] Since the daytime running light 2 provided in the embodiment of the present application needs to be integrated on the existing heavy truck headlamp body 1, and since the daytime running light 2 is essentially a signal lamp for providing identification signals of the vehicle position for other drivers, it belongs to a signal lamp. Therefore, the light intensity cannot refer to the light intensity of the low beam lamp and the width indicator lamp, but needs to meet the requirements of GB23255-2019 "Photometric Characteristics of Motor Vehicle Daytime Running Lamps".

[0047] Based on this, in the embodiment of the present application, the LED lamp 21 can be specifically configured as four 0.5-watt LED lamps 21 connected in series to ensure the light distribution requirements.

[0048] It should be noted that the number, power and arrangement of the LED lamps 21 can be adjusted according to the light distribution requirements, but are not limited thereto.

[0049] In the present application embodiment, Figure 3 As shown, the circuit board 23 includes a circuit board, and the circuit board is connected with four LED lamps LW1-LW4, a transient voltage suppression diode TVS, a capacitor C1, a load R3, a rectifier diode DV1 and a current limiting circuit, specifically:

[0050] Four LED lamps LW1-LW4 are connected in series to form the light source of the daytime running lamp 2;

[0051] The transient voltage suppression diode TVS is connected in parallel with the light source to prevent transient voltage surges at both ends of the light source;

[0052] Capacitor C1 is connected in parallel with the light source to form a filter circuit to eliminate high-frequency signals in the current passing through the light source;

[0053] Load R3 is connected in parallel with the light source as a dummy load in the circuit to prevent the no-load voltage from floating high;

[0054] The rectifier diode DV1 is connected in series with the light source to prevent the two ends of the light source from being subjected to reverse voltage;

[0055] The current limiting circuit is connected in series with the light source to play a current limiting role and ensure that the current flowing through the light source is not overloaded.

[0056] The current limiting circuit may include 9 resistors R1-R9 connected in parallel, and the resistance value may be 1K.

[0057] Since the daytime running lights 2 need to be turned on automatically during daytime driving, no matter what gear the driver puts the transmission in, it will not affect the state of the daytime running lights 2. Therefore, the daytime running lights 2 need to ensure long-term stable operation. Therefore, the above-mentioned limitation on the working current, etc. through the specific setting of the circuit board 23 can effectively prevent the current overload through the LED lamp 21, ensure the service life of the LED lamp 21 and ensure that the LED lamp 21 is in a stable working state.

[0058] In the embodiment of the present application, the circuit board 23 is connected to the control module of the heavy truck, and the control module is used to send a control signal to the circuit board 23;

[0059] The circuit board 23 controls the LED light 21 according to the control signal to keep it turned on all the time when the vehicle is running during the day.

[0060] Specifically, the control module includes an ignition detection module, a switch control module, and a light detection module;

[0061] The ignition detection module is connected to the first input end of the switch control module, the light detection module is connected to the second input end of the switch control module, and the output end of the switch control module is connected to the circuit board 23;

[0062] Among them, the ignition detection module is used to detect the vehicle ignition signal and send the vehicle ignition signal to the switch control module in real time;

[0063] The light detection module is used to detect the ambient light brightness through a photosensitive device and send the ambient light brightness signal to the switch control module in real time;

[0064] The switch control module is used to determine whether to turn on the LED lamp 21 through the circuit board 23 according to the vehicle ignition signal and the ambient light brightness signal.

[0065] Among them, the ignition detection module can be the vehicle body ECU (abbreviation of Electronic Control Unit, that is, the electronic control unit);

[0066] In addition, the control module can also be connected to a brightness adjustment module. The brightness adjustment module is used to send a brightness adjustment signal to the control module, and the control module controls the working state of the LED lamp 21 according to the brightness adjustment signal;

[0067] The brightness adjustment module can be a manual brightness adjustment module to facilitate the driver to make independent control according to needs.

[0068] Although the present application has been described in detail with general descriptions and specific embodiments above, on the basis of the present application, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present application all fall within the scope claimed by the present application.
