Technical Field

[0001] The utility model relates to the technical field of automobile control switches, in particular to a control switch for adjusting the projection angle and brightness of a vehicle headlamp. Background Art

[0002] An automotive lighting control switch is a device used to control various vehicle lights. Typically located on a joystick beneath the steering wheel or on the dashboard, it allows the driver to conveniently adjust and manage the vehicle's lighting system. Using this control, the driver can turn on or off various lights, including headlights, side marker lights, fog lights, and turn signals. These lights provide essential illumination and signaling functions for the driver, ensuring driving safety at night or in poor visibility conditions.

[0008] As a preferred solution of the present invention, the roller is rotatably mounted on the inner notch of the panel via a shaft, and is freely rotated with the shaft as the rotation center. Anti-slip grooves are provided on the outer surface of the roller.

[0009] As a preferred solution of the present invention, the top and bottom of the guide rod are both provided with protruding ends, and the top of the guide rod is clamped on the bottom of the roller through the protruding ends.

[0010] As a preferred solution of the present invention, the metal sheet and the shaft of the roller are connected by a key, and the outer side of the metal sheet is in contact with the PCB mainboard.

[0011] As a preferred solution of the present invention, a conducting circuit is provided on the PCB main board, and the metal sheet is treated with beryllium copper and electroplated with silver.

[0012] As a preferred solution of the present invention, a scale value is further provided at the middle position of the outer surface of the roller, and the scale value is processed by precise engraving technology.

[0013] Beneficial effects: In view of the problems that still exist in the control switch for adjusting the vehicle headlights in the prior art, in the utility model, 1. through the structure of the roller, guide rod, spring, metal sheet and PCB main board, the guide rod is pressed when the roller rolls to put force on the spring, and the spring will give a reaction force to the guide rod, and the force puts force on the roller. When the roller is rolled, a gear position feeling of the roller is generated; at the same time, the compression rebound force value of the spring is used to control the force required for the rolling of the roller, so as to meet the operating feel of the roller; 2. The metal sheet is fixed to the roller through the shaft, and the metal spring is driven to move when the roller is rolled, and the roller drives the metal sheet to roll at different angles. The metal sheet contacts the PCB main board, and the PCB main board has a set conduction circuit. After the metal sheet and the PCB main board contact, different circuits are connected to realize the transmission of different signals, thereby controlling the different brightness and lighting angles of the car lights, which is very practical.
