Further, as shown in fig. 9 and 14, a plurality of buckles 2313 for limiting the circuit board 221 are vertically arranged on one side of the light shielding plate 2311 close to the lamp shade 30, and a plurality of grooves 2211 matched with the buckles 2313 are formed in the side wall of the circuit board 221.

Preferably, the reflection structure 232 is disposed adjacent to the handle portion 212 and located inside the handle portion 212, specifically, extends from the mounting portion 231 toward the cover body 211 and the lampshade 30 in an inclined or curved manner, in this embodiment, the reflection structure 232 extends toward the light-emitting portion 301 of the lampshade 30 at a side of the limiting structure 2112 toward the housing 110, so that light emitted by the light-emitting element 222 can be substantially reflected and refracted by the reflection structure 232 to the light-emitting portion 301 and guided out without being irradiated onto the limiting structure 2112.

Further, the light source 220 and the lampshade 30 are arranged in a staggered mode in the height direction of the door body 1, and the reflecting structure 232 and the lampshade 30 are arranged oppositely in the horizontal direction, so that light rays of the light source 220 are enabled to enter the reflecting structure 232 basically and are projected out through reflection and refraction, the light rays cannot directly irradiate the lampshade 30, and the uniformity of the light rays guided out is guaranteed.

The invention also provides an installation method of the refrigerator door body, which comprises the following steps: the trim assembly 20 is installed at one end of the door body 10 along the height direction of the door body 1, and then the lamp shade 30 is installed on the door body 10 along the front-rear direction perpendicular to the door body 1, so that one end of the lamp shade 30 in the height direction of the door body 1 is fixed on the trim cover plate 210, and the other end is fixed on the door body 10 and aligned with the housing 110 along the height direction of the door body 1. The light shade 30 is mainly exposed on the front side of the refrigerator door body 1 like the outer shell 110, and only needs to be partially aligned with the outer shell 110, and the light shade 30 may have the same shape as the outer shell 110, that is, the outer surface is located on the same plane as the outer surface of the outer shell 110, and may also be configured to have a certain shape, such as an arc shape or other curved or folded shape, for improving the visual perception.

Referring to fig. 15 to 16, a second preferred embodiment of the present invention is shown, in this embodiment, since the structures of the door body 10 and the lamp shade 30 in the refrigerator door body 1 and the connection relationship between the door body and the molding assembly 20 are the same as those in the first embodiment, in order to avoid redundancy, the present embodiment only deals with the structure of the molding assembly 20 different from the first embodiment.

Referring to fig. 15 and 16, in the present embodiment, the molding assembly 20 includes a molding cover 210 and a light source 220 located inside the molding cover 210. The molding cover 210 includes a cover body 211 and a handle 212 formed to protrude from the cover body 211 toward the light source 220.
