[0022] As described in the background technology, in heavy rain, water mist easily forms on the road surface, blocking the line of sight. At this time, it is necessary to turn on the wipers and fog lights in HI gear at the same time. However, the wipers and fog lights are arranged on both sides of the steering wheel. It is cumbersome to turn them on quickly, and it is easy to distract the driver. In response to this technical problem, the publication number CN217170631U discloses a synchronous controller for automobile fog lights and wipers. However, in actual application, when the wipers are turned to HI gear, the fog lights are turned on at the same time. At this time, if the driver turns on the fog lights switch at the same time based on normal operation, it will cause a short circuit in the wiper motor, so that the wipers will not work, which is easy to cause safety accidents.

[0023] Based on this, the inventor has created a synchronous controller for automobiles of the present application to solve the above technical problems.

[0026] like Figure 1As shown, a synchronous controller for a high-speed wiper and fog lamp 30 for an automobile, the rotary terminal of the wiper switch 10 is connected to the positive pole of the power supply 40 or the negative pole of the power supply 40, one end of the wiper motor 20 is correspondingly connected to the negative pole of the power supply 40 or the positive pole of the power supply 40, the other end of the wiper motor 20 is respectively electrically connected to the HI, MIST, INT, LO or OFF gear terminal of the wiper switch 10, the high-speed gear terminal of the wiper motor 20 is connected in series with the fog lamp 30 on the line of the wiper motor 20, the two ends of the fog lamp 30 are respectively electrically connected to the positive and negative poles of the power supply 40, and the fog lamp switch 31 is connected in series between one of the two ends of the fog lamp 30 and the positive or negative pole of the power supply 40. For example, the rotary terminal of the wiper switch is electrically connected to the positive pole of the power supply 40. The synchronous controller for automobile further includes an electromagnet 50, which is arranged on the connection line between the HI gear terminal and the wiper motor 20 and is not on other gear lines of the wiper switch 10, and the electromagnet 50 is connected in series with the HI gear terminal. Here, that is to say, the electromagnet 50 is energized only when the wiper switch 10 is in the HI gear, and the electromagnet 50 cannot be energized when the wiper switch 10 is in other gears or the fog lamp 30 is turned on alone. When the electromagnet 50 is energized, it is suitable for magnetically fixing the disconnected fog lamp switch 31. Here, that is to say, the electromagnet 50 is arranged adjacent to the fog lamp switch 31 to magnetically fix the fog lamp 30 in the disconnected state, so that the driver is not easy to close the fog lamp 30.

[0027] The automobile synchronous controller of the utility model is based on the existing technology, and an electromagnet 50 is added. The electromagnet 50 is set on the connection line between the HI gear terminal and the wiper motor 20 and is not on other gear lines of the wiper switch 10. The electromagnet 50 is connected in series with the HI gear terminal. When the electromagnet 50 is energized, it is suitable for magnetically fixing the disconnected fog lamp switch 31. In heavy rain, when the driver turns the wiper to the HI gear, the fog lamp 30 is turned on together. The driver may want to turn on the fog lamp 30 at the same time based on normal operation. By setting the electromagnet 50, the electromagnet 50 is energized when it is in the HI gear, and the fog lamp switch 31 is magnetically fixed, thereby effectively avoiding the driver's misoperation and shutting down the wiper to avoid causing a safety accident.

[0028] In another embodiment, the automobile synchronous controller further includes a first balancing resistor and a second balancing resistor, wherein the second balancing resistor is disposed on a line between the fog lamp 30 and the power source 40, and the second balancing resistor is connected in parallel with the first balancing resistor, the electromagnet 50, and the HI gear terminal. Here, the first balancing resistor and the second balancing resistor are disposed to reduce the occurrence of short circuit.

[0029] In another embodiment, the automobile synchronous controller further includes a prompter 60, the prompter 60 is connected in series with the electromagnet 50, and the prompter 60 is arranged on the connection line between the HI gear terminal and the wiper motor 20 and is not on other gear lines of the wiper switch 10. Preferably, the prompter 60 includes a voice prompter 60. By providing the prompter 60, the driver can be effectively prompted that the fog lamp 30 and the HI gear wiper are both turned on at the same time, further reducing the situation where the driver turns off the fog lamp 30.

[0030] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
