The term "ECU" is simply the brain of the vehicle ".
The existing ECU is generally characterized in that a plurality of elements are installed in one ECU shell and then fixed in a vehicle, and the ECU is not easy to generate abnormality because the vehicle body is generally vibrated little when the vehicle runs on a flat road, but the ECU is easy to be damaged because of the welding-off of connecting points of various elements caused by severe vibration generated when the vehicle runs on a pothole of a road surface.
Disclosure of Invention
The invention provides the anti-vibration shell of the reversing system ECU, which can reduce the vibration of the anti-vibration shell of the ECU when the automobile vibrates severely, and effectively prevent the damage of components in the ECU.
In order to solve the technical problems, the invention is solved by the following technical scheme: the utility model provides a vibration-proof casing of back system ECU, includes locating support, circuit board box, electric putter, buffering oil tank and controlling means, be provided with upward open-ended guide way on the locating support, the guide way bottom is provided with the oil feed oil duct and the oil outlet duct that all connect the buffering oil tank, the bore of oil feed oil duct is greater than the oil outlet duct, be provided with on the oil feed oil duct to the check valve of oil feed in the guide way, circuit board box bottom is provided with the guide bar, the guide bar is in slide in the guide way, electric putter set up in the bottom of guide way, electric putter's telescopic link upwards passes the bottom surface of guide way, motor on the electric putter is connected with motor controller, be provided with the acceleration sensor that is used for detecting vertical direction acceleration on the locating support, motor controller with acceleration sensor all connects controlling means, when acceleration sensor detects vertical decurrent acceleration, controlling means control motor controller is supplied power to the motor on the electric putter, electric putter loses down when stretching out to the decurrent acceleration. This kind of vibration-proof casing of reverse system ECU detects vertical decurrent acceleration when acceleration sensor, controlling means control motor control is to the motor power supply on the electric putter, the electric putter rises to the time of losing vertical decurrent acceleration and withdraws, and the in-process guide bar that stretches out at the electric putter upwards removes and pours into the guide way with the buffer oil through the check valve into, after the electric putter withdraws, the slow decline of guide bar and with the buffer oil from the oil duct pressure back buffer oil tank to the purpose that has reached the reduction vibration has been played.
In the above technical solution, preferably, the electric push rod has a section of telescopic rod located in the guide groove when fully retracted, and a connection position of the oil inlet duct and the oil outlet duct is located on a side surface of the guide groove below the section of telescopic rod. The structure ensures that the oil inlet passage and the oil outlet passage can be communicated with the guide groove in the whole lifting process of the guide rod.
Compared with the prior art, the invention has the following beneficial effects: this kind of vibration-proof casing of reverse system ECU detects vertical decurrent acceleration when acceleration sensor, controlling means control motor control is to the motor power supply on the electric putter, the electric putter rises to the time of losing vertical decurrent acceleration and withdraws, and the in-process guide bar that stretches out at the electric putter upwards removes and pours into the guide way with the buffer oil through the check valve into, after the electric putter withdraws, the slow decline of guide bar and with the buffer oil from the oil duct pressure back buffer oil tank to the purpose that has reached the reduction vibration has been played.
