Oil filling port box of passenger car

Abstract

The invention discloses an oil filling port box of a passenger car, which comprises an oil filling port box body. The oil filling port box body is a thin-walled part formed by means of integrally stamping, a mounting hole for an oil tank opening mechanism is arranged on a side wall of the oil filling port box body, a mounting hole for an oil filling port is disposed at the bottom of the oil filling port box body, and three bolt through holes are arranged on the periphery, which is close to the edge of the mounting hole for the oil filling port, of the oil filling port box body. The oil filling port box is characterized in that an outer flange is disposed at the edge of an opening of the oil filling port box body, and a gluing groove which is continuously distributed along the opening of the oil filling port box body is disposed on the outer flange. Compared with the prior art, the oil filling port box for the passenger car has the advantages that due to the gluing groove and the flange structure, gluing positions can be determined easily, gluing is carried out easily, a sealing effect of sealant can be guaranteed, and accordingly the problem of water and air leakage at the opening of the oil filling port box are effectively solved.

Description

technical field [0001] The invention relates to auto parts, in particular to a fuel filler box for a car. Background technique [0002] The fuel filler box is an important structural part in the car body. Usually, the bottom of the fuel filler box is connected to the fuel pipe, and the upper part is overlapped with the side wall. In general design, a certain gap should be reserved between the upper edge of the fuel filler box and the side wall to avoid interference between the fuel filler box and the side wall due to deviations caused by welding accuracy. In order to ensure the tightness of the overlap between the upper edge of the fuel filler box and the side wall, sealant is usually applied to the flange of the fuel filler box to fill the gap between the fuel filler box and the side wall to prevent water and air leakage here. At present, manual gluing is mostly used for gluing here, and the control of the gluing position and the uniformity of gluing are difficult to contr...
