Embodiment Construction
[0026] In order to enable those skilled in the art to better understand the technical solution of the present application, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] The orientation terms such as up, down, left, right, front and rear in this application document are established based on the positional relationship shown in the drawings. If the drawings are different, the corresponding positional relationship may also change accordingly, so this should not be understood as limiting the scope of protection.
[0028] In the present invention, the terms "installation", "connection", "connection", "connection", "fixation" and so on should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated Connection can also be mechanical connection, electrical connection or mutual communication, direct connection or indirect connection through an intermedia...

The invention relates to an elastic damping structure and a connection method. The damping structure comprises a fastener and a damping assembly; the damping assembly connects an upper mounting plate with a lower mounting plate together through the fastener; the lower mounting plate is provided with a mounting hole; the damping assembly comprises an upper elastic damping cushion, a lower elastic damping cushion and an elastic damping cylinder; the upper and lower elastic damping cushions are provided with through holes with the same sizes correspondingly; the outer diameter of the elastic damping cylinder is matched with the inner diameters of the through holes of the upper and lower elastic damping cushions; the elastic damping cylinder penetrates through the mounting hole of the lower mounting plate; the elastic damping cylinder is sleeved with the upper and lower elastic damping cushions; and the upper and lower elastic damping cushions are located on the upper and lower sides of the lower mounting plate correspondingly. The elastic damping structure is simple in structure, easy to machine and manufacture and easy to assemble, at the time of using, mounting is convenient, the damping effect is good, and universality is high.
Description
technical field [0001] The invention relates to the technical field of vehicle vibration reduction, in particular to an elastic vibration reduction structure and a connection method. Background technique [0002] ECU (Electronic Control Unit) is usually installed on the vehicle chassis through the ECU bracket, and a vibration damping pad is arranged between the ECU and the ECU bracket, and the ECU, the vibration damping pad and the ECU bracket are fixed together by bolts. However, in this structure, the tightening force of the bolts is difficult to control, and loosening is likely to occur if the force is small, while excessive force will cause excessive deformation of the rubber pad, reduce the vibration damping effect, and keep the rubber pad in a fastened state for a long time , easy to break due to aging. In addition, due to the rigid connection between the bolt and the ECU bracket, the vibration damping effect of the above structure is poor, which cannot meet the vibra...
