Detailed Description

In order to more clearly illustrate the embodiments of the present invention, the following description will explain embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.

The three-in-one charger shock absorption structure of the new energy automobile of the embodiment is shown in fig. 1 and fig. 2, and comprises a connecting support 10 and a shock absorption stud 20, wherein the charger 30 is installed on the connecting support 10, and the connecting support 10 is connected with a new energy automobile motor assembly 40 through the shock absorption stud 20. As shown in fig. 3 and 4, the shock absorbing stud 20 includes an elastic damping column 21 and a screw 22, the elastic damping column 21 of the present embodiment is a rubber column, the screw 22 has a screw head 22-1 with a diameter larger than that of the screw, the screw heads of the screws are embedded into the rubber column at two ends thereof, and the screws at two ends of the rubber column are coaxial; a metal washer 23 and a metal nut 24 are mounted on the screws at both ends, respectively. In order to improve the damping effect, the rubber column of the damping stud has an axial corrugated structure so as to increase the axial deformation capacity of the damping stud.

The motor is a main vibration source of an automobile body, the connecting support 10 is connected with a shell of the motor, shock absorption studs 20-1 and 20-2 are required to be arranged at the connection positions, one ends of the shock absorption studs are fixed on the connecting support 10 through gaskets and bolts, and the other ends of the shock absorption studs are fixed on the shell of the motor through gaskets and bolts. At present, the right driving shaft of most automobiles is longer due to the larger wheel track, and the problems of acceleration deviation and easy resonance of the right driving shaft exist, so that a driving shaft transition support is required to be arranged on the right driving shaft to effectively support the shaft rod. Therefore, in order to further effectively isolate vibration, a shock absorption stud 20-3 is arranged at the joint of the connecting bracket 10 and the driving shaft transition bracket 50 of the motor assembly, one end of the shock absorption stud is fixed on the connecting bracket through a gasket and a bolt, and the other end of the shock absorption stud is fixed on the driving shaft transition bracket through a gasket and a bolt. The suspension is an automobile power assembly part used for reducing and controlling the transmission of engine vibration and playing a supporting role, a shock absorption stud 20-4 is also arranged at the joint of the connecting bracket 10 and a suspension bracket 60 of the motor assembly, one end of the shock absorption stud is fixed on the connecting bracket through a gasket and a bolt, and the other end of the shock absorption stud is fixed on the suspension bracket through the gasket and the bolt.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
