The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 2, a preferred embodiment of the vehicle load control device 2 of the present invention is applicable to a vehicle (not shown) having an engine. The vehicle load control device 2 includes a power supply unit 21, an output unit 22, and a power detector. A detecting unit 23 that measures the engine speed and generates a corresponding speed signal, and a controller 24 that can receive the speed signal generated by the detecting unit 23. In the preferred embodiment, the detecting unit 23 is a pulse signal sensor.

The power supply unit 21 includes a battery 211 and a start switch 212 electrically connected to the battery 211. The output unit 22 includes a high voltage coil 221 electrically connected to the start switch 212, and a spark plug 222 electrically connected to the high voltage coil 221. And a switch 223 electrically connected to the start switch 212 and a light group 224 controlled by the switch 223. In the preferred embodiment, the vehicle light set 224 is the headlight of the vehicle.

The load control unit 242 has a receiving module 243 for receiving the speed signal, a signal comparison module 244 electrically connected to the receiving module 243 and storing a set speed value, and an electrical connection module 244. And a power control module 245 of the vehicle light group 224. In the preferred embodiment, the receiving module 243 is electrically connected to the ignition unit 241 to receive the rotational speed signal, and the set rotational speed value in the signal comparison module 244 is 2000 rpm.

It should be particularly noted that, since the ignition unit 241 and the load control unit 242 are electrically connected to each other, the detection unit 23 can be electrically connected to the load control unit 242 as shown in FIG. 3, The same effect can be achieved.

The signal comparison module 244 performs an alignment of the rotational speed signal with the set rotational speed value.

When the speed signal is greater than the set speed value (ie, 2000 rpm), the power control module 245 controls the battery 211 to output a general voltage to make the brightness of the vehicle light group 224 fully bright; and when the speed signal is less than the set speed The value is such that the power control module 245 controls the battery 211 to output a low voltage (about 8-10 V) to make the brightness of the light group 224 semi-bright, thereby reducing the power consumption of the battery 211 at a low speed of the vehicle.

With the above design, the vehicle load control device 2 of the present invention has the following advantages in practical applications:

1. High component utilization: Compared with the existing ignition control device 1 (shown in FIG. 1), the vehicle load control device 2 of the present invention integrates the ignition unit 241 and the load control unit 242 into the controller 24 to detect the Detector The detecting unit 23 detects that the rotational speed signal generated by the engine speed is simultaneously applied to the ignition explosion of the spark plug 222, and the brightness control of the vehicle light group 224 effectively improves the component utilization rate.

2. Cost reduction: Continued above, due to improved component utilization, Effectively reduce the number of components required to use and reduce production costs.

3. Reduce space waste: Continued above, because the number of components can be reduced, the required installation space can be greatly reduced, which not only reduces the waste of space, but also effectively reduces the overall volume.

4. The service life is long: the load control unit 242 cooperates with the detection unit 23 to detect the rotation speed signal generated by the engine speed, so that the brightness of the vehicle light group 224 can be changed with the engine speed, thereby reducing the The battery 211 consumes power at a low rotational speed of the vehicle to facilitate charging of the battery 211 when the vehicle is at a low rotational speed, thereby effectively increasing the service life of the battery 211.

In summary, the vehicle load control device 2 of the present invention uses the detecting unit 23 to detect the engine speed and generate a corresponding speed signal, and the controller 24 controls the ignition timing of the high voltage coil 221 with the speed signal. The brightness of the lamp group 224 can not only effectively improve the utilization between components, but also reduce the cost and space waste, and at the same time reduce the power consumption of the battery 211 at low speed of the vehicle, so as to facilitate low speed of the vehicle. The battery 211 can still be charged, effectively increasing the service life of the battery 211, so that the object of the present invention can be achieved.
