DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment 1 is a suspension vibration reduction assembly, and the suspension vibration reduction assembly includes a vibration reduction bracket 1 and a vibration reduction washer 2.

The vibration reduction washer 2 is installed at the connection between the slide rail 5 and the mounting frame 4, and is used to absorb the vibration force transmitted from the slide rail 5 to the battery box 3. The vibration reduction bracket 1 and the vibration reduction washer 2 are both made of vibration-suppressing alloy material.

[0028] Based on practical applications, such as Figure 1 As shown, the vibration-damping bracket 1 includes an upper mounting surface 11, a lower mounting surface 12 and two side surfaces 13. An upper mounting hole 14 and a lower mounting hole 15 for the mounting parts to pass through are respectively provided on the upper mounting surface 11 and the lower mounting surface 12, and the upper mounting hole 14 and the lower mounting hole 15 are coaxial. A transversely penetrating weight-reducing hole 16 is provided in the middle of the vibration-damping bracket 1, and the weight-reducing hole 16 is parallel to the upper mounting surface 11 and the lower mounting surface 12. A transition step 17 is provided between the upper mounting surface 11 and the lower mounting surface 12 and the side surface 13. The edge of the transition step 17 is a circular arc chamfer. The two side surfaces 13 are designed as curved surfaces for absorbing vibration forces. The functions of the vibration-damping hole, the transition step 17 and the curved surface are to reduce the structural stiffness and meet the bearing strength requirements.

[0029] Based on practical applications, such as Figure 2 and Figure 3As shown, the vibration-damping washer 2 includes a top surface 21 and an annular wall surface 22. A circle of openings 23 is provided on the inner side of the vibration-damping washer 2, so that the cross section of the vibration-damping washer 2 is semicircular to meet the requirement of reducing structural rigidity. The distance between the opening 23 and the top surface 21 of the vibration-damping washer 2 is greater than the distance between the opening 23 and the annular wall surface 22 to meet the bearing strength requirement. The top surface 21 of the vibration-damping washer 2 is a plane to meet the bearing strength requirement.

[0030] During installation, if Figure 4 As shown, a vibration-damping bracket 1 made of a vibration-damping alloy is added to the bolt connection between the mounting frame 4 and the battery box 3 , and a vibration-damping washer 2 made of a vibration-damping alloy is added to the bolt connection between the slide rail 5 and the mounting frame 4 .

[0031] Experimental example: Battery box 3 simulation calculation

The experimental example mainly consists of a battery box 3, a mounting frame 4, a slide rail 5, bolts, nuts, a vibration-damping bracket 1, and a vibration-damping washer 2. A flat washer is used as a comparative example, and a flat washer is added to the bolt connection between the mounting frame 4 and the battery box 3, and a flat washer is added to the bolt connection between the slide rail 5 and the mounting frame 4.
