Description

It can effectively and reasonably manage and distribute power supplies of different voltages and powers, and can also allocate corresponding voltages to different loads, thus effectively managing and distributing different loads. Power distribution modules are installed in many electrical devices.
[0003] For new energy vehicles, a vehicle may be equipped with multiple power distribution modules to achieve power distribution and control of different power systems of the vehicle.
[0004] Among the existing automobile lights, such as headlights, turn signals, low beams, high beams and taillights, only the headlights and taillights will automatically turn on or off according to the start or reversing light signal. The other lights are not equipped with a power distribution module for unified distribution and management with the headlights and taillights. Different drivers have different driving habits. For example, when changing lanes or turning, they are not used to turning on the corresponding turn signals, which increases safety risks. Or when the light becomes weak in tunnels or near night, some drivers feel that they can still see and do not turn on the headlights. However, even if they can see in time, their field of vision will be reduced by the influence of light, and not turning on the headlights will also increase safety hazards.

[0021] It should be noted that when an element is referred to as "fixed to" or "set on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. It should be understood that the orientation or position relationship indicated by the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0022] The following is combined with Figure 1 The utility model is further described in detail:
[0023] See attached Figure 1 As shown, a power distribution module includes a vehicle body steering detection module, a light detection module, a reverse detection module, a micro control unit and a relay; the vehicle body steering detection module, the light detection module and the reverse detection module are respectively connected to the micro control unit, the micro control unit is connected to the relay, and the relay is respectively connected to the left turn signal, the right turn signal, the high beam, the low beam and the tail light of the vehicle. It also includes a vehicle start detection module, and the vehicle start detection module is connected to the micro control unit.
[0024] The above scheme also includes multiple input interfaces, which respectively receive the detection results of the vehicle body steering detection module, the light detection module, and the reversing detection module. The relay includes a first relay, a second relay, a third relay, a fourth relay, and a fifth relay, the first relay is connected to the left turn signal, the second relay is connected to the right turn signal, the third relay is connected to the high beam, the fourth relay is connected to the low beam, and the fifth relay is connected to the tail light.
[0025] The vehicle body steering detection module is used to detect the steering direction and angle of the vehicle body, and transmit the steering direction and angle to the micro control unit; the light detection module is used to detect the light intensity in the vehicle driving environment, and transmit the light intensity signal to the micro control unit; the reversing detection module is used to detect the reversing signal of the vehicle, and transmit the detected reversing signal to the micro control unit; the vehicle start detection module is used to detect the vehicle start signal, and transmit the vehicle start signal to the micro control unit.
[0026] The microcontroller unit is provided with a vehicle body steering angle threshold. When receiving the vehicle body steering direction and steering angle, the microcontroller unit compares the steering angle with a preset vehicle body steering angle threshold. When the comparison result shows that the left steering angle or the right steering angle of the vehicle body is greater than the vehicle body steering angle threshold, the microcontroller unit controls the first relay or the second relay to engage, thereby turning on the left turn signal or the right turn signal to inform other drivers within a certain area of the steering situation, thereby avoiding the situation where some drivers do not have good driving habits and do not turn on the corresponding turn signal when changing lanes or turning, thereby effectively reducing the safety risks during driving.
[0027] The microcontroller unit is provided with an ambient light intensity threshold. During vehicle driving, the light detection module detects the light intensity in the driving environment in real time and transmits a light intensity signal to the microcontroller unit. When the microcontroller unit receives the ambient light intensity, it compares it with a preset ambient light intensity threshold. When the comparison result shows that the ambient light intensity is weaker than the ambient light intensity threshold, the third relay is controlled to engage to turn on the high beam.
[0028] When the vehicle is started, the vehicle start detection module detects the vehicle start signal and transmits the signal to the micro control unit. When the micro control unit receives the vehicle start signal, it controls the fourth relay to close and turn on the low beam.
[0029] When the reversing detection module detects the reversing signal of the vehicle, it transmits the reversing signal of the vehicle to the micro control unit. When the micro control unit receives the reversing signal, it controls the fifth relay to be attached to turn on the reversing light.
[0030] The power distribution module also includes a headlight status detection module and an alarm module, both of which are connected to the micro control unit. The headlight status detection module is used to detect the status of each headlight on the vehicle and transmit the status of each headlight to the micro control unit. When the micro control unit determines that a headlight is abnormal based on the received signals of the status of each headlight, it sends a control signal to the alarm module, and the alarm module performs alarm processing to inform the driver of the abnormal situation of the headlight.
[0031] In summary, the power distribution module of the utility model detects the steering situation of the vehicle body, the light intensity, and the reversing detection situation respectively by setting the vehicle body steering detection module, the light detection module, and the reversing detection module. The microcontroller unit controls the relays of the left turn signal, the right turn signal, the high beam, the low beam, and the tail light respectively according to the detection results of each detection module, and then controls the opening and closing of each light. The power distribution module realizes the effective management and control of each light of the car, and effectively reduces the safety risks during driving. It effectively avoids the situation that some drivers are not used to turning on the corresponding turn signal during the lane change process, or do not turn on the high beam when the light intensity affects the driver's field of vision and clarity, which increases the risk during driving.
