Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and more specifically, particularly relates to a seismic isolation block. Background Art

[0002] It is usually necessary to install seismic isolation blocks on cars to prevent damage to other structural parts of the car body due to excessive impact and to prevent abnormal noise caused by metal contact. Most of the existing seismic isolation blocks are composed of positioning frames, waterproof covers, positioning pins, buffer sleeves, rubber pads, etc. When the car is impacted, the rubber pads and buffer sleeves are deformed to cushion the car. The rubber pads will rub against the buffer sleeves during the deformation and rebound process. Long-term use will easily cause wear and aging of the rubber pads. Once the rubber pads are damaged, the shock-absorbing effect of the seismic isolation blocks will be affected. Therefore, the seismic isolation blocks need to be replaced regularly.

[0003] For example, CN217539461U discloses an automobile seismic isolation block assembly that is easy to disassemble, which relates to the field of automobile parts technology, and includes: a base and a seismic isolation part; three fixing bolts are inserted into the base, and the three fixing bolts are all installed on the vehicle body; three auxiliary grooves are provided on the bottom end surface of the base in a circular array, and the three auxiliary grooves are respectively aligned with the positions of the three fixing bolts; through the setting of the auxiliary holes, because three auxiliary holes are provided on the mounting seat in a circular array, and the three auxiliary holes are respectively aligned with the positions of the three fixing bolts, then when the mounting seat is buffered and seismic isolated up and down, the airflow ejected from the auxiliary holes can achieve wind cleaning at the fixing bolts, so when removing the fixing bolts, there is no need to clean the dust at the fixing bolts separately, which solves the problem that the existing device needs to unscrew all the nuts during disassembly, and the disassembly is not convenient and quick enough.

[0004] Based on the above, since the hardness of the rubber pad is lower than that of the buffer sleeve, the buffer sleeve is mostly not damaged when the rubber pad is worn. However, the rubber pad is usually riveted to the buffer sleeve. When replacing, most of the time, the isolation block is directly replaced as a whole, which causes certain waste and increases the maintenance cost of the car. Utility Model Content
