Description

Rubber combined pad for automobile Technical Field The utility model relates to the technical field of automobiles, in particular to a rubber combination pad for an automobile. Background While the automobile is running, jolt and even tremble are generated, friction and impact are generated among parts of the automobile, and in order to avoid direct impact and abrasion among the parts, rubber pads are needed to be additionally arranged so as to relieve the abrasion and impact of the parts. Most rubber pads in the prior art are made of single rubber materials, and are used for buffering vibration in an elastic mode, under long-term use, high-frequency vibration in the running process of an automobile is faced, plastic deformation is easy to generate, the elastic performance of the rubber pads is reduced, the damping effect and the service life of the rubber pads are further affected, and the single rubber materials are not easy to effectively block oil liquid, gas and dust from invading. In view of this, we provide a rubber mat for an automobile. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the rubber combination pad for the automobile, which solves the technical problem that the damping and buffering performances of a rubber pad are easy to be reduced after long-term use by adopting a single rubber material in the prior art, achieves the aim of improving the damping performances of the whole device through a multi-layer composite structure and a modularized design, and can also prevent the invasion of oil liquid, gas and dust, and improves the assembly sealing performance of the device. In order to solve the technical problems, the utility model provides the technical scheme that the rubber combined pad for the automobile comprises a ferrule, wherein a shock absorption sealing mechanism for relieving pressure in multiple layers is arranged in the ferrule. The shock attenuation sealing mechanism is including installing the bottom cushion at the inside lower place of lasso, the multiunit buffering bump is installed on bottom cushion top, the middle level cushion is installed on bottom cushion top, the ball groove that multiunit and buffering bump position correspond has been seted up to middle level cushion bottom, the inside multiunit buffer spring that just is located ball groove top of middle level cushion is connected with, the top layer cushion is installed on middle level cushion top, the energy-absorbing stick that the multiunit is array distribution is installed on top layer cushion top. Preferably, the upper end and the lower end of the inner side of the ferrule are provided with sealing grooves, and sealing ring sleeves matched with the sealing grooves are arranged on the outer walls of the bottom rubber cushion and the surface rubber cushion.
