BRIEF DESCRIPTION OF THE DRAWINGS
[0010] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments recorded in this application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.
[0011] Figure 1 It is a circuit connection diagram of the utility model.
[0012] The numbers in the accompanying drawings are: 1. DC power supply, 2. first wire, 3. body controller, 4. second wire, 5. first lamp, 6. intervention switch, 7. third wire, 8. LIN bus communication module, 9. second lamp, 10. fourth wire, 11. ground wire. DETAILED DESCRIPTION
[0013] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0014] See Figure 1 The figure shows an electrical inspection tool for automobile front combination lamps, including a DC power supply 1, the positive pole of the DC power supply 1 is connected to the body controller 3 through a first wire 2, and one side of the body controller 3 is connected to a first lamp 5 through a second wire 4; one side of the first lamp 5 is connected to the negative pole of the DC power supply 1 through a wire; an intervention switch 6 is provided on the second wire 4; the other side of the body controller 3 is connected to one end of the first lamp 5 through a ground wire 11; the body controller 3 is connected to a LIN bus communication module 8 through a third wire 7 and a fourth wire 10 respectively, and one side of the LIN bus communication module 8 is connected in parallel with a second lamp 9, and the second lamp 9 is connected in parallel with the first lamp 5 and then connected to the negative pole of the DC power supply 1.
[0015] The first lamp 1 includes a low beam, a high beam, and a front fog lamp. The second lamp 9 includes a daytime running lamp and a turning headlamp. The DC power supply 1 is a 12V or 24V low-voltage DC power supply. The vehicle body controller 2 is a BCM, CBCU, or ECU.
[0016] The operating principle of the automotive front combination lamp electrical inspection tool is as follows:
[0017] First, when the intervention switch 6 is off, the DC power supply 1 drives the body controller 3 to operate. The first wire 2 to the body controller 3 is the power line and the hazard warning switch signal line respectively. At this time, the body controller 3 drives the second lamp 9, namely the daytime running light and the turn signal, through the LIN bus communication module 8 connected by the third wire 7 and the fourth wire 10. At this time, you can see that the flashing yellow light is the turn signal, and the white light with a weaker brightness is the daytime running light;
[0018] When the intervention switch 6 is turned on, the DC power supply 1 also drives the first lamp 1, ie, the low beam lamp, the high beam lamp and the front fog lamp, and three white light sources with high brightness can be observed.
[0019] This application achieves electrical inspection of the front combination lamps by lighting up the low-brightness light source of the daytime running lamp with the high and low beams and fog lamps at different times to avoid the weak light being covered by the strong light.
[0020] 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.
