The power utilization component (201) is arranged on the body (200) to improve the use experience of the refrigerator, and the power utilization component (201) can be a display, a inductor or an electric heating wire and other power utilization components.

the power utilization part (201) on the body (200) is connected with the connection end (301) through the wiring harness (400) arranged in the body (200). The control part (101) and/or the power supply part (102) arranged on the box body (100) are connected with the second connection end (302) through the wiring harness (400) arranged in the box body (100). when the body (200) closes the opening of the box body (100), the connection end (301) is in contact connection with the second connection end (302), the power utilization part (201) is electrically connected with the control part (101) and/or the power supply part (102), the power supply or/and control of the power utilization part (201) are realized, when the body (200) is opened, the connection end (301) is disconnected with the second connection end (302), and the power utilization part (201) is disconnected.

The body (200) opens or closes the opening of the box body (100) to disconnect or connect the connection end (301) from the second connection end (302).

The connection terminal (301) and the second connection terminal (302) may include a transmission terminal Tx and a reception terminal Rx for electrical signal communication, respectively, and a power supply terminal Vcc and a ground terminal Gnd, etc.

The th connection end (301) is arranged on the inner edge (203) of the body (200), the second connection end (302) is correspondingly arranged on the opening circumference (103) of the box body (100), when the body (200) closes the box body (100), the inner edge (203) of the body (200) is tightly attached to the opening circumference (103) of the box body (100), and the th connection end (301) is contacted with the second connection end (302).

In order to realize that the power utilization component (201) is continuously supplied with power when the body (200) is opened and the connection end (301) is disconnected with the second connection end (302), a standby power supply (202) is arranged in the body (200) to supply power to the power utilization component (201) so as to ensure that the power utilization component (201) can normally work under the condition that the body (200) is opened.

When the body (200) closes the box body (100), the connection of the connection end (301) and the second connection end (302) realizes the electrical connection of the standby power supply (202) and the power supply part (102) in the box body (100), and the standby power supply (202) is suitable for charging by using the power supply part (102) of the box body (100).

Referring to fig. 4 and 5, schematic diagrams showing different states of connecting or disconnecting the connection terminal and the second connection terminal in the embodiment of the refrigerator of the present invention are shown.

As shown in fig. 4 and 5, the th connection end (301) is convexly disposed on the inner edge (203) of the body (200) toward the box body (100) and is substantially perpendicular to the inner edge (203). the opening peripheral edge (103) of the box body (100) is disposed with the cavity (500), the second connection end (302) is disposed in the cavity (500), and the cavity (500) can be closed by the openable cover (600). as shown in fig. 5, when the body (200) closes the box body (100), the th connection end (301) is pushed into the cavity (500), and the cover (600) is pushed open, and when the body (200) is opened, the th connection end (301) is withdrawn from the cavity (500), the cover (600) naturally falls down due to its own weight and closes the cavity (500).

The cavity (500) is further provided with a spring element (700) matched with the second connecting end (302), when the second connecting end (302) is acted by an external force, the spring element (700) contracts to generate a reaction force on the second connecting end (302). As shown in FIG. 5, after the body (200) closes the opening of the box body (100), the connecting end (301) is pushed into the cavity (500) and is abutted against the second connecting end (302) to realize connection, the connecting end (301) is acted on the second connecting end (302), correspondingly, the spring element (700) contracts to generate an elastic force and is acted on the second connecting end (302) to enable the second connecting end (302) to have a tendency of repelling the connecting end (301). in this way, the connecting end (301) and the second connecting end (302) abut against due to the action force of repelling each other, and are connected tightly.

Referring to fig. 6 and 7, schematic diagrams showing different states of connecting or disconnecting the connection terminal and the second connection terminal in another embodiment of the refrigerator according to the present invention are shown.

The difference between the embodiment and the embodiment of the refrigerator shown in fig. 4 and 5 is that the second connecting end 302 disposed in the cavity 500 does not need to be engaged with a spring member, and the second connecting end 302 is disposed as a spring piece fixed in the cavity 500 and deformed by an external force to generate an elastic force.

As shown in FIG. 7, when the body (200) closes the opening of the box (100), the connection end (301) is pushed into the cavity (500) and abuts against the second connection end (302) to achieve connection, the connection end (301) acts on the second connection end (302), and accordingly, the second connection end (302) is elastically deformed to generate elastic force and react against the connection end (301), so that the second connection end (302) has a tendency to repel the connection end (301), and thus, the connection end (301) and the second connection end (302) tightly abut against due to the acting force repelling each other, and are connected more tightly and firmly.

In summary, the connection end (301) and the second connection end (302) are in contact connection instead of the prior art that the connection is realized by the wire harness passing through the hollow rotating shaft, so that the body (200) and the box body (100) can be electrically connected more simply and conveniently, how the wire harness passes through the rotating shaft and is influenced by the rotation process of the body switch does not need to be considered, the design is simple, and the production and assembly processes are reduced.
