Expansion equipment connector damping device for truck body in white

Abstract

The invention discloses an expansion equipment connector damping device for a truck body in white. The damping device comprises a bottom plate, a main damping air bag, an auxiliary damping air bag andfour bearing plates, wherein the main damping air bag is mounted on the bottom plate; the auxiliary damping air bag is bonded to the top of the main damping air bag; fixing holes are formed in the three corners of each bearing plate, and the other corner of each bearing plate is perpendicularly connected with a fixing column; two hydraulic dampers are arranged on the edge of each side of the bottom plate; the top ends of every two hydraulic dampers are connected with a spring fixing plate; two spring fixing plates are also arranged at the top of the auxiliary damping air bag; every two edgesof the four bearing plates are connected; the fixing columns are located on the sides, away from the bottom plate, of the bearing plates and located on the outermost sides of the four bearing plates;springs are arranged in the fixing holes of the bearing plates; the lower ends of the springs are connected with the spring fixing plates; the upper ends of the springs are connected with spring fixing caps; and the spring fixing caps are fixed to the bearing plates through sleeves with threads. By the adoption of the expansion equipment connector damping device, expansion equipment can be mountedconveniently, and vibration of the expansion equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to an expansion equipment connector damping device for a truck body-in-white. Background technique [0002] The back wall of the truck body-in-white is usually separated from the inside and outside of the cockpit by a rolled steel plate of about 0.8-1mm, which does not provide any functions. Install the expansion device on the mounting hole. However, due to the different sizes and shapes of the expansion devices, it is difficult to install the expansion devices directly on the mounting holes. Contents of the invention [0003] The object of the present invention is to provide a shock-absorbing device for an expansion equipment connector used in a truck body-in-white, which can facilitate the installation of the expansion equipment and reduce the vibration of the expansion equipment. [0004] In order to solve the above-mentioned technical problems, a technical solu...
