The invention relates to a shock absorbing structure and shock absorbing method of a localized protection device, so as to solve the problems of large volume, high cost and easy aging of shock absorbing materials of the localized protection device shock absorbing structure in the prior art. The shock absorbing structure of the localized protection device comprises a device housing and a printed circuit board arranged in the device housing. An elastic buffer is arranged between the printed circuit board and the device housing, and the printed circuit board is fixed on the device housing throughthe elastic buffer. The shock absorbing method of the localized protective device comprises fixing a printed circuit board on a device housing through an elastic buffer, and performing shock absorption on the printed circuit board separately through the elastic buffer between the printed circuit board and the device housing. The printed circuit board is subjected to shock absorption through the elastic buffer separately, the overall volume of the device can be reduced, the cost can be reduced, and the aging of the shock absorbing material is effectively slowed down, which is conducive to prolonging the service life, improving the reliability, reducing the monitoring and maintenance costs.
