Description

Technical Field

Background
Automotive safety systems are becoming increasingly important in automotive design. To this end, automobiles typically include sensor systems that are used to alert the driver and in some cases automatically enable certain safety devices and dynamic stabilization systems. The sensor system may be designed to trigger a vehicle safety system or vehicle reaction system such as the deployment of an airbag, automatic braking, or the reduction of engine torque in the event of a preset condition. In such systems, the vehicle includes sensor components that detect ambient conditions and dynamic conditions such as acceleration.
The detection means, which may comprise a number of detection devices such as accelerometers or angular velocity sensors, continuously detect data and provide said data to the main circuit board, which in turn provides the data to the control assembly. These sensing devices are typically in electrical and mechanical communication with the main circuit board, and the main circuit board is in electronic communication with the control assembly. If the detection means detects a change beyond a preset limit, the control module will activate the relevant safety equipment and/or the vehicle reaction system. Since the slow invocation of safety systems or automotive reaction systems is highly undesirable, the control component needs to reliably detect these conditions.
Such sensor packages must therefore operate reliably when subjected to vibrations and other interferences. Since the sensing device is typically mechanically connected to the main circuit board to which the power cable is connected, one source of vibration and noise is the main circuit board itself. The main circuit board vibrates to influence the working sensitivity of the sensor suite; meanwhile, the existing sensor device for the electric automobile is poor in heat dissipation effect, the temperature in the sensor suite rises after the main circuit works for a long time or after heat of other parts of the electric automobile is transferred, and particularly in high-temperature weather, due to the fact that the circuit board is deformed and expansion of different materials is inconsistent, the circuit board is subjected to cold joint or welding cracking; ultimately affecting the operation of the motorized plate and the sensors.
