In the specific implementation process, the first surface, the second surface, the third surface, the fourth surface, the fifth surface and the sixth surface can all be made of metal aluminum, so that the box-type shock absorbing device of the present invention has a certain shielding function to reduce the electromagnetic interference generated in the system, and the inside of the first box body 1 and other communication power supplies are all connected by a conversion plug installed on the rear side of the first box body 1. The box-type shock absorbing device is a fully sealed box body part, which is used to ensure electromagnetic isolation between it and other boxes, and isolation from external moisture and heat; in another specific implementation of the present embodiment, the cross section of the first box body 1 can also be circular;

[0030] The shock absorbing unit is connected to the inner wall of the first box body 1, and includes a plurality of spring sheets 2 nested in sequence, each spring sheet 2 includes a first section 201, a second section 202, a third section 203 and a fourth section 204 connected in sequence, the cross sections of the first section 201, the second section 202 and the fourth section 204 are all straight-line-shaped, and there are angles between the second section 202 and the first section 201 and the fourth section 204; the cross section of the third section 203 is arc-shaped, for providing a buffering and shock absorbing space, and the fourth section is in contact with the product 1 to be shock-absorbing; the bending radius of the third section 203 of each of the sequentially nested spring sheets 2 decreases in sequence, and different bending radii are selected because spring sheets bent with different radii will produce different elasticities, so as to achieve To meet the actual use requirements; the first section 201 and the fourth section 204 of the adjacent shrapnel 2 are both fitted, and there is a certain gap between the second section 202 and the third section 203. A multi-layer thin sheet metal shrapnel 2 is used instead of a single-layer metal. The multi-layer type has softer elasticity and higher fatigue resistance. There is a first gap between the second section 202 and the second section 202 of the adjacent shrapnel 2; there is a second gap between the third section 203 and the third section 203 of the adjacent shrapnel, which is used as a change space for the stress bending metal to produce plastic deformation; the shrapnel 2 can be selected from 65Mn spring steel, SUS301, tin phosphor bronze, beryllium copper, etc., and appropriate heat treatment processes, failure treatment processes, surface treatment processes, etc. can be selected according to actual conditions to form different shrapnel 2;

The number of shock absorbing units that matches the actual weight distribution can be installed, and the bottom of the box is uniformly processed with linear array mounting holes, which are symmetrically arranged in pairs in the first box, and the fourth sections of each spring piece 2 in the two symmetrically arranged shock absorbing units are connected by a connecting plate, which is used to install components with the same or different functions to complete the same or different functions.
