Problems solved by technology
Due to the characteristics of the rubber material itself, the existing vibration damping device has exposed the rubber aging, deformation, and failure of the vibration damping device after long-term exposure to high temperature in the engine compartment, oil environment, and vibration caused by the vehicle on harsh road conditions such as undulating roads. Shortcomings, and the strength of the existing vibration damping device in the horizontal direction is insufficient, and in the case of impacts with complex changes in frequency and amplitude, there will be a problem of horizontal fracture

Embodiment Construction
[0030] Below in conjunction with embodiment the present invention is described in further detail:
[0031] Such as figure 1 , figure 2 , image 3 As shown, a vibration damping device for an engine controller includes a sleeve 1, a buffer filling material 2, an electrorheological fluid 6b, a positive electrode terminal 6a, a negative electrode terminal 6c, and a circuit. The main material of the buffer filler material 2 is rubber. The filling material 2 is filled with an electromorphic interlayer, and the two metal electrodes of the electromorphic interlayer pass through the stainless steel cylinder 1 and lead out through the outer skin insulated and high-temperature-resistant cables. Inside the electrorheological interlayer is a particle-dispersed electrorheological fluid, which is a suspended dispersion formed by uniformly dispersing high-dielectric solid particles with a particle size of 0.1-10 μm in low-dielectric insulating silicone oil. There is a mold cavity inside t...

Description
technical field [0001] The invention relates to the technical field of vibration damping equipment, in particular to a vibration damping device for an engine controller. Background technique [0002] As the core key component of the engine, the controller determines whether the engine can work normally and affects its performance and reliability. With the high integration requirements of the engine, it is most suitable to arrange the controller on the engine to reduce the extra weight brought by the external arrangement of the controller. However, when the engine is working, there will be large vibrations, such as direct rigid connection, which will affect the reliability and life of the electronic components in the controller, so it is necessary to install a suitable vibration damping device. The present invention is designed for the controller to be installed on the engine The vibration damping device can effectively reduce the impact of engine vibration on the controller...
