Abstract

The invention discloses a power battery mounting structure. The structure comprises a rear floor and a mounting box, wherein the rear section of the rear floor is sunken downwards to form a spare tirepool, the mounting box is fixed below the spare tire pool, a containing cavity is formed in the mounting box, an opening communicated with the containing cavity is formed in the top end of the mounting box, and a lap joint flange fixedly connected with the lower surface of the spare tire pool is arranged at the opening; a through hole is formed in the position, corresponding to the opening, of the spare tire pool. The structure is advantaged in that a problem that the power battery cannot be installed due to insufficient depth or insufficient structural strength of the spare tire pool can besolved, reliability is high, and cost is low. The utility model further discloses a vehicle which comprises a rear floor assembly, and the rear floor assembly comprises the power battery mounting structure.
