In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: backing system ECU is anti-
Shell, including locating support, circuit board cabinet, electric pushrod, buffer oil tank and control device are shaken, is set on the locating support
It is equipped with the guide groove of upward opening, the guiding trench bottom is provided with the oil inlet oil duct and fuel-displaced oil duct for being all connected with buffer oil tank,
The bore of the oil inlet oil duct is greater than the fuel-displaced oil duct, and the list of the oil inlet into the guide groove is provided on the oil inlet oil duct
To valve, the circuit board bottom of box is provided with guide rod, and the guide rod slides in the guide groove, the electric pushrod
It is set to the bottom of the guide groove, the telescopic rod of the electric pushrod is upward through the bottom surface of the guide groove, described electronic
Motor on push rod is connected with electric machine controller, is provided on the locating support for detecting adding for vertical direction acceleration
Velocity sensor, the electric machine controller and the acceleration transducer are all connected with control device, when the acceleration transducer
When detecting acceleration straight down, the control device controls the electric machine controller and supplies the motor on electric pushrod
Electricity, the retraction when electric pushrod extend out to the acceleration lost straight down.This kind of shockproof shell of backing system ECU is accelerating
When degree sensor detects acceleration straight down, the control device controls the electric machine controller on electric pushrod
Motor, the retraction when electric pushrod rises to the acceleration lost straight down, in the process that electric pushrod stretches out
Middle guide rod, which is moved up, is injected into buffering oil in guide groove by check valve, and after electric pushrod retraction, guide rod is slow
Decline and buffering oil from fuel-displaced oil duct is pushed back into buffer oil tank, achieved the purpose that reduce vibration to play.
In above-mentioned technical proposal, it is preferred that there is one section of telescopic rod to be located at described lead when the electric pushrod is fully retracted
Into slot, the link position of the oil inlet oil duct and the fuel-displaced oil duct is located at the guide groove side below this section of telescopic rod
Face.The overall process that the structure goes up and down oil inlet oil duct and fuel-displaced oil duct in guide rod can guarantee oil inlet oil duct and fuel-displaced oil
Road can be connected to guide groove.
The utility model compared with prior art, has the following beneficial effects: that this kind of shockproof shell of backing system ECU is adding
When velocity sensor detects acceleration straight down, the control device controls the electric machine controller on electric pushrod
Motor, the retraction when electric pushrod rises to the acceleration lost straight down, electric pushrod stretch out mistake
Guide rod, which is moved up, in journey is injected into buffering oil in guide groove by check valve, and after electric pushrod retraction, guide rod is slow
Buffering oil is simultaneously pushed back buffer oil tank from fuel-displaced oil duct by slow decline, has achieved the purpose that reduce vibration to play.
Detailed description of the invention
