Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted refrigerators, and in particular relates to a connection structure between a rear cover and a shell of a vehicle-mounted refrigerator. Background Art

[0002] The refrigerator shell processing needs to reserve a gap, and reserve a 9*12*7.5MM gap between the conventional shell return edge boss and the rear cover contact surface (need to be reserved on both sides); synchronize the shell return edge contour shaping at the conventional box frame plugging rib position, and reserve a gap of 0.6MM;

[0003] In order to solve the assembly gap between the conventional shell and the rear cover box frame, the main gap in the conventional assembly is that the rear cover (blow-molded part) is inserted into the side surface of the box frame without being fixed by screws, which easily causes an obvious gap between the rear cover and the box frame; now a connection structure between the rear cover and the shell of a car refrigerator is proposed to improve this type of assembly gap.
