Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and particularly to a refrigerator. Background Art

[0002] At present, the door body of a refrigerator is usually provided with electronic control components such as a display screen, and the electronic control components need to be electrically connected to the main control board located inside the box body. In the related art, the electronic control components are generally electrically connected to the main control board through electric connection lines. However, during the process of opening and closing the door body, the electric connection lines are prone to breakage. Summary of the Invention

[0003] The embodiments of the present application provide a refrigerator, which can solve the technical problem that the electric connection lines are prone to breakage during the process of opening and closing the door body in the related art.

[0004] In a first aspect, the embodiments of the present application provide a refrigerator, which includes:

[0005] A box body, which is configured with a refrigerating compartment;

[0006] A door body, which is rotatably connected to the box body to open or close the refrigerating compartment;

[0007] A first electric connection line, which is arranged on the box body;

[0008] A second electric connection line, which is arranged on the door body;

[0009] An electric connection device, which includes:

[0010] At least one first conductive member, which is arranged on the box body and is electrically connected to the first electric connection line, and the first conductive member is provided with a conductive protrusion;

[0011] At least one second conductive member, which is arranged on the door body, is arranged corresponding to at least one of the first conductive members, and is electrically connected to the second electric connection line. The second conductive member is provided with a conductive contact surface, the conductive contact surface abuts against the conductive protrusion, and the extension trajectory of the conductive contact surface is the same as the rotation trajectory when the door body rotates relative to the box body.

[0012] The refrigerator according to the embodiment of the present application is provided with an electrical connection device. The electrical connection device is provided with a first conductive member electrically connected to a first electrical connection line and a second conductive member electrically connected to a second electrical connection line. The first conductive member may be provided with a conductive protrusion. The second conductive member is provided with a conductive contact surface, and the conductive contact surface abuts against the conductive protrusion. The extension locus of the conductive contact surface is the same as the rotation locus when the door body rotates relative to the cabinet body. When the door body is opened and closed, the second conductive member can be driven to move during the rotation of the door body relative to the cabinet body, so that the conductive contact surface moves relative to the conductive protrusion. Since the extension locus of the conductive contact surface is the same as the rotation locus of the door body, the conductive protrusion can always be in contact with the conductive contact surface, so that the first electrical connection line and the second electrical connection line are always electrically connected, and the first electrical connection line and the second electrical connection line can be prevented from being repeatedly bent, thereby improving the connection reliability of the first electrical connection line and the second electrical connection line.

[0013] In some embodiments of the present application, the refrigerator further includes a first rotating shaft. The first rotating shaft is arranged along the height direction of the cabinet body. The first end of the first rotating shaft is connected to the cabinet body, and the second end of the first rotating shaft is rotatably connected to the door body around the axis of the first rotating shaft; the extension locus of the conductive contact surface is an arc, and the center of the arc is located on the axis of the first rotating shaft.

[0014] With such an arrangement, the door body is rotatably connected to the cabinet body through the first rotating shaft. When the door body rotates relative to the cabinet body, its rotation locus is an arc with the center on the axis of the first rotating shaft. The extension locus of the conductive contact surface is an arc with the center on the axis of the first rotating shaft, and the extension locus of the conductive contact surface is the same as the rotation locus of the door body. When the door body is opened and closed, the door body can drive the second conductive member to move, so that the conductive contact surface slides relative to the conductive protrusion. During the sliding process, the conductive protrusion is always in contact with the conductive contact surface, thereby improving the connection reliability between the first conductive member and the second conductive member.

[0015] In some embodiments of the present application, the refrigerator further includes a second rotating shaft and a third rotating shaft. The second rotating shaft and the third rotating shaft are both arranged along the height direction of the cabinet body. The first end of the second rotating shaft is connected to the cabinet body, and the second end of the second rotating shaft is rotatably connected to the door body around the axis of the second rotating shaft and is slidably connected to the door body along a first locus; the first end of the third rotating shaft is connected to the cabinet body, and the second end of the third rotating shaft is rotatably connected to the door body around the axis of the third rotating shaft and is slidably connected to the door body along a second locus different from the first locus; the extension locus of the conductive contact surface includes a first straight line segment, a curve segment and a second straight line segment connected in sequence, and the first straight line segment, the curve segment and the second straight line segment enclose part of the second rotating shaft and part of the third rotating shaft.

[0016] With such a setting, the door body is rotatably connected to the box body through the second rotating shaft and the third rotating shaft. When the door body rotates relative to the box body, the second rotating shaft slides and rotates within the second sliding recess, and the third rotating shaft slides and rotates within the second sliding recess, such that the rotation trajectory of the door body is a first straight line segment, a curved segment, and a second straight line segment connected in sequence, and the first straight line segment, the curved segment, and the third straight line segment enclose a portion of the second rotating shaft and the third rotating shaft. With such a setting, during the process of opening and closing the door body, the edge of the door body can be prevented from exceeding the side surface of the box body, so that the refrigerator can be embedded into the cabinet body, that is, the refrigerator is an embedded refrigerator. The extending trajectory of the conductive contact surface is a first straight line segment, a curved segment, and a second straight line segment connected in sequence, and the first straight line segment, the curved segment, and the second straight line segment enclose a portion of the second rotating shaft and the third rotating shaft. The extending trajectory of the conductive contact surface is the same as the rotation trajectory of the door body. When opening and closing the door body, the door body can drive the second conductive member to move, such that the conductive contact surface slides relative to the conductive protrusion, and during the sliding process, the conductive protrusion is always in contact with the conductive contact surface, improving the reliability of the electrical connection between the first conductive member and the second conductive member.

[0017] In some embodiments of the present application, the refrigerator further includes a cover plate, the cover plate is connected to the top end of the box body and is rotatably connected to the top end of the door body, and the cover plate is provided with a second connection hole; the first conductive member is inserted into the second connection hole, the top end of the first conductive member extends out of the second connection hole and is connected to the first electrical connection line; the bottom end of the second conductive member extends out of the second connection hole to form the conductive protrusion.

[0018] With such a setting, the top end and the bottom end of the first conductive member can be respectively arranged on the upper and lower sides of the cover plate, and the cover plate can separate the top end and the bottom end of the first conductive member to prevent problems such as short circuit caused by the first electrical connection line contacting the conductive contact surface, improving the connection reliability of the electrical connection device.

[0019] In some embodiments of the present application, the conductive protrusion is a bent structure, the bent structure bends away from the door body, and the bent structure abuts against the conductive contact surface.

[0020] With such a setting, the bent structure makes the conductive protrusion elastic, so that the conductive protrusion can always abut against the conductive contact surface, thereby improving the connection reliability between the conductive protrusion and the conductive contact surface.

[0021] In some embodiments of the present application, the electrical connection device further includes a first mounting member, the first mounting member is inserted into the second connection hole, the first mounting member is provided with a third connection hole, and the third connection hole is for the first conductive member to pass through.

[0022] With such an arrangement, the first conductive member can be connected to the cover plate through the first mounting member. When replacing and repairing the first conductive member, the first mounting member inserted with the first conductive member can be first removed from the second connection hole of the cover plate, and then the first conductive member can be replaced and repaired. Compared with the technical solution in which the first conductive member is directly inserted into the second connection hole of the cover plate, it is not necessary to disassemble the cover plate when replacing and repairing the first conductive member, which improves the convenience of replacing and repairing the first conductive member.

[0023] In some embodiments of the present application, a fourth connection hole is provided at the top end of the door body; the second conductive member includes a conductive portion, a bent portion, and a connecting portion that are connected in sequence. The conductive portion extends in a direction parallel to the top end of the door body, and the conductive contact surface is provided on a side of the conductive portion facing away from the door body; part of the bent portion and part of the connecting portion are located on a side of the conductive portion facing the door body, and part of the bent portion and part of the connecting portion are in contact with the top end of the door body; the connecting portion passes through the fourth connection hole, and one end of the connecting portion extending out of the fourth connection hole is electrically connected to the second electrical connection line.

[0024] With such an arrangement, by arranging part of the bent portion and part of the connecting portion on the side of the conductive portion facing away from the door body, and connecting the other part of the bent portion to the conductive portion. When the conductive protrusion abuts against the conductive contact surface of the conductive portion, the conductive protrusion applies a downward pressure to the conductive portion, and the other part of the bent portion connected to the conductive portion moves towards the door body, causing the bent portion to be further bent to generate an upward elastic force. This elastic force causes the other part of the bent portion and the conductive portion to move upward, so that the conductive portion can abut against the conductive protrusion, preventing the conductive contact surface from separating from the conductive protrusion and improving the reliability of the electrical connection device.

[0025] In some embodiments of the present application, the electrical connection device further includes a second mounting member, the second mounting member is mounted on the top end of the door body, at least one guiding recess is provided on a side of the second mounting member facing away from the door body, and the extending trajectory of the guiding recess is the same as the rotation trajectory of the door body, and the guiding recess is used to accommodate the conductive portion.

[0026] With such an arrangement, the second conductive member can be connected to the door body through the second mounting member. When replacing and repairing the second conductive member, the second mounting member connected with the second conductive member can be first disassembled from the door body, and then the second conductive member can be replaced and repaired. Compared with the technical solution in which the second conductive member is directly connected to the door body, it is not necessary to disassemble the door body when replacing and repairing the second conductive member, which improves the convenience of replacing and repairing the second conductive member.

[0027] In addition, during the process of opening and closing the door body, when the conductive protruding portion slides on the conductive contact surface, the opposite side walls of the guiding recessed portion can limit and guide the conductive protruding portion, so that the conductive protruding portion can slide along the extending direction of the conductive contact surface, preventing the conductive protruding portion from detaching from the conductive contact surface, and improving the functional reliability of the electrical connection device.

[0028] In some embodiments of the present application, an extension portion is provided on one side of the second mounting member facing the door body. The extension portion passes through the fourth connection hole, and a fifth connection hole is provided in the extension portion. The fifth connection hole communicates with the guiding recessed portion, and the connecting portion passes through the fifth connection hole.

[0029] With such a setting, by providing the extension portion with the fifth connection hole, the connecting portion can pass through the fifth connection portion, and the extension portion can protect the connecting portion to prevent the connecting portion from interfering with other components, improving the safety of the electrical connection device.

[0030] In a second aspect, an embodiment of the present application provides a refrigerator, which includes:

[0031] A box body, which is configured with a refrigerating compartment, and the box body is connected with a first electrical connection line;

[0032] A door body, which is rotatably connected to the box body to open or close the refrigerating compartment;

[0033] A first electrical connection line, which is arranged on the box body;

[0038] Wherein, one of the corresponding first conductive member and the second conductive member is provided with a conductive protruding portion, and the other is provided with a conductive contact surface. The extending trajectory of the conductive contact surface is the same as the rotation trajectory when the door body rotates relative to the box body. During the process of opening or closing the door body, the conductive protruding portion is always in contact with the conductive contact surface.

[0039] The refrigerator according to the embodiment of the present application is provided with an electrical connection device, which is used to connect a first electrical connection line arranged on the box body and a second electrical connection line arranged on the door body. The electrical connection device is provided with a first conductive member electrically connected to the first electrical connection line and a second conductive member electrically connected to the second electrical connection line, and a conductive protrusion and a conductive contact surface in contact with each other are arranged between the first conductive member and the second conductive member. The extension trajectory of the conductive contact surface is the same as the rotation trajectory when the door body rotates relative to the box body. During the process of opening or closing the door body, the conductive protrusion can slide along the extension trajectory of the conductive contact surface, so that the conductive protrusion and the conductive contact surface are always in contact with each other, and further the first electrical connection line and the second electrical connection line are always electrically connected, preventing the first electrical connection line and the second electrical connection line from being repeatedly bent, and improving the connection reliability of the first electrical connection line and the second electrical connection line.

[0074] To make the purpose, implementation mode and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation mode of this application in combination with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0075] It should be noted that the brief description of the terms in this application is only for the convenience of understanding the following described implementation mode, rather than intending to limit the implementation mode of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0076] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0078] The terms "first", "second" and other similar terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined by the terms "first", "second" and other similar terms may explicitly or implicitly include one or more of such features.

[0079] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0080] In the related art, for a refrigerator, there is a technical problem that the electrical connection line is prone to breakage during the process of opening and closing the door body. Through the research of the inventor, it is found that the reason is as follows: in the related art, the electrical connection line is usually arranged through the top ends of the box body and the door body. The first end of the electrical connection line is electrically connected to the main control board installed on the box body, and the second end of the electrical connection line is electrically connected to the electrical control component installed on the door body. When opening and closing the door body, a part of the electrical connection line electrically connected to the electrical control component will move relative to the other part of the electrical connection line following the door body, causing the electrical connection line to bend. When opening and closing the door body multiple times, the electrical connection line will be fatigued and broken due to repeated bending, thereby reducing the connection reliability between the main control board and the electrical control component, and further reducing the functional reliability of the refrigerator.

[0081] The inventor has tried to enhance the anti-bending performance of the electrical connection line. However, for an electrical connection line with strong anti-bending performance, its cost is relatively high, which will increase the cost of the refrigerator. Or, generally, the door body and the box body are rotationally connected through a rotating shaft. The inventor has also tried to set the rotating shaft as a hollow shaft and arrange a part of the electrical connection line inside the hollow shaft to prevent the electrical connection line from being repeatedly bent when opening and closing the door body. However, for an embedded refrigerator, the diameter of the rotating shaft is usually small, and it is impossible to set the rotating shaft as a hollow shaft. Therefore, how to prevent the electrical connection line from breaking during the process of opening and closing the door body has become a technical problem that needs to be solved urgently.

[0082] In view of this, the embodiment of the present application provides a refrigerator, which is provided with an electrical connection device for connecting the first electrical connection line arranged on the box body and the second electrical connection line arranged on the door body. The electrical connection device is provided with a first conductive part electrically connected to the first electrical connection line and a second conductive part electrically connected to the second electrical connection line, and there are a conductive protrusion and a conductive contact surface in contact between the first conductive part and the second conductive part. The extension trajectory of the conductive contact surface is the same as the rotation trajectory when the door body rotates relative to the box body. During the process of opening or closing the door body, the conductive protrusion can slide along the extension trajectory of the conductive contact surface, so that the conductive protrusion and the conductive contact surface are always in contact, and further the first electrical connection line and the second electrical connection line are always electrically connected, and it can prevent the first electrical connection line and the second electrical connection line from being repeatedly bent, improving the connection reliability between the first electrical connection line and the second electrical connection line.

[0083] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0084] Referring to Figure 1 , the refrigerator according to the embodiment of the present application may include a box body 100 and a door body 200. The box body 100 may be configured with a refrigerating compartment. The door body 200 is rotatably connected to the box body 100 to open or close the refrigerating compartment.

[0085] The refrigerator may further include a first electrical connection line and a second electrical connection line (not shown in the drawings). The first electrical connection line may be disposed on the box body 100. Exemplarily, a main control board may be disposed inside the box body 100, and the first electrical connection line may be electrically connected to the main control board. The second electrical connection line may be disposed on the door body 200. Exemplarily, an electronic control component such as a display screen 210 may be installed on the door body 200, and the second electrical connection line may be electrically connected to the display screen 210. It can be understood that, in addition to the main control board, the first electrical connection line may also be connected to other components; in addition to electronic control components such as the display screen 210, the second electrical connection line may also be connected to other components, which will not be elaborated in the embodiments of the present application. Hereinafter, taking the first connection line being electrically connected to the main control board and the second electrical connection line being electrically connected to the display screen 210 as an example, the technical solutions in the embodiments of the present application will be described.

[0086] The refrigerator according to the embodiment of the present application may further include an electrical connection device 300. The electrical connection device 300 is used to connect the first electrical connection line and the second electrical connection line, so that the main control board located inside the box body 100 is electrically connected to the display screen 210 installed on the door body 200, so that the main control board can control the display screen 210 to implement related functions of the refrigerator.

[0087] Exemplarily, referring to Figure 2 , the electrical connection device 300 may be disposed at the top end of the box body 100 and the top end of the door body 200. For example, an end cover 220 may be disposed at the top end of the door body 200. The refrigerator may further include a cover plate 110. The cover plate 110 may be connected to the top end of the box body 100, and the cover plate 110 may also be rotatably connected to the end cover 220 located at the top end of the door body 200. The electrical connection device 300 may be disposed on the end cover 220 and the cover plate 110. The electrical connection device 300 may also be disposed at other positions of the box body 100 and the door body 200, which will not be elaborated in the embodiments of the present application.

[0088] Referring to Figure 3, the electrical connection device 300 may include at least one first conductive member 310 and at least one second conductive member 320 corresponding to the at least one first conductive member 310. The first conductive member 310 is disposed on the cabinet 100 and electrically connected to the first electrical connection line. The second conductive member 320 is disposed on the door body 200 and electrically connected to the second electrical connection line. One of the corresponding first conductive member 310 and second conductive member 320 may be provided with a conductive protrusion 311, and the other may be provided with a conductive contact surface 321. The extending trajectory of the conductive contact surface 321 may be the same as the rotation trajectory when the door body 200 rotates relative to the cabinet 100. During the process of opening or closing the door body 200, the conductive protrusion 311 is always in contact with the conductive contact surface 321.

[0089] In the refrigerator according to the embodiment of the present application, an electrical connection device 300 is provided. The electrical connection device 300 is used to connect the first electrical connection line disposed on the cabinet 100 and the second electrical connection line disposed on the door body 200. The electrical connection device 300 is provided with a first conductive member 310 electrically connected to the first electrical connection line and a second conductive member 320 electrically connected to the second electrical connection line. A conductive protrusion 311 and a conductive contact surface 321 in contact with each other are provided between the first conductive member 310 and the second conductive member 320. The extending trajectory of the conductive contact surface 321 is the same as the rotation trajectory when the door body 200 rotates relative to the cabinet 100. Refer to Figure 4 and Figure 5 , during the process of opening or closing the door body 200, the conductive protrusion 311 can slide along the extending trajectory of the conductive contact surface 321, so that the conductive protrusion 311 is always in contact with the conductive contact surface 321, and further the first electrical connection line and the second electrical connection line are always electrically connected, preventing the first electrical connection line and the second electrical connection line from being repeatedly bent, and improving the connection reliability of the first electrical connection line and the second electrical connection line.

[0090] In addition, the electrical connection device in the embodiment of the present application does not need to be disposed inside the rotating shaft. Even if the size of the rotating shaft is small, it can still be applicable, improving the applicable range of the electrical connection device.

[0091] Exemplarily, refer to Figure 3 , the first conductive member 310 may be provided with a conductive protrusion 311. The second conductive member 320 is provided with a conductive contact surface 321. The conductive contact surface 321 is in contact with the conductive protrusion 311. The extending trajectory of the conductive contact surface 321 is the same as the rotation trajectory when the door body 200 rotates relative to the cabinet 100. Refer to Figure 4 and Figure 5, when the door body 200 is opened or closed, during the process of the door body 200 rotating relative to the box body 100, the door body 200 can drive the second conductive member 320 to move, so that the conductive contact surface 321 moves relative to the conductive protrusion 311. Since the extension trajectory of the conductive contact surface 321 is the same as the rotation trajectory of the door body 200, the conductive protrusion 311 can always be in contact with the conductive contact surface 321, so that the first electrical connection line and the second electrical connection line are always electrically connected, and it can prevent the first electrical connection line and the second electrical connection line from being repeatedly bent, improving the connection reliability of the first electrical connection line and the second electrical connection line, and further preventing the main control board from being disconnected from the display screen 210, resulting in the refrigerator being unable to implement the function of displaying information.

[0092] In some possible implementation manners of the embodiments of the present application, the first conductive member 310 may also be provided with a conductive contact surface 321, and the second conductive member 320 may also be provided with a conductive protrusion 311. When the door body 200 is opened or closed, the door body 200 can drive the second conductive member 320 to move, so that the conductive protrusion 311 slides on the conductive contact surface 321 and is always in contact with the conductive contact surface 321.

[0093] The extension trajectory of the conductive contact surface 321 may be the same as the rotation trajectory of the door body 200. Therefore, according to different rotation trajectories of the door body 200, the extension trajectory of the conductive contact surface 321 can be set so that the electrical connection device 300 can be applicable to refrigerators with different rotation trajectories of the door body 200. Exemplarily, referring to Figures 3 to 5 , the refrigerator may further include a first rotating shaft 120. The first rotating shaft 120 is arranged along the height direction of the box body 100, and the first end of the first rotating shaft 120 may be connected to the box body 100. For example Figure 3 as shown, and referring to Figure 8 , the cover plate 110 may be provided with a first connection hole 111. The first end of the first rotating shaft 120 may be provided with a clamping recess 121. The first connection hole 111 may be sleeved on the first rotating shaft 120, and a part of the cover plate 110 close to the first connection hole 111 may be clamped in the clamping recess 121 to enhance the connection strength between the cover plate 110 and the first rotating shaft 120. The second end of the first rotating shaft 120 is rotatably connected to the door body 200 around the axis of the first rotating shaft 120. For example, the end cover 220 may be provided with a rotation connection hole 221, and the second end of the first rotating shaft 120 may be inserted into the rotation connection hole 221 and be rotatable in the rotation connection hole 221. The extension trajectory of the conductive contact surface 321 may be an arc, and the center of the arc may be located on the axis of the first rotating shaft 120.

[0094] The door body 200 is rotatably connected to the box body 100 through the first rotating shaft 120. When the door body 200 rotates relative to the box body 100, its rotation trajectory is an arc with the center on the axis of the first rotating shaft 120. The extending trajectory of the conductive contact surface 321 is an arc with the center on the axis of the first rotating shaft 120, and the extending trajectory of the conductive contact surface 321 is the same as the rotation trajectory of the door body 200. When opening and closing the door body 200, the door body 200 can drive the second conductive member 320 to move, so that the conductive contact surface 321 slides relative to the conductive protrusion 311. During the sliding process, the conductive protrusion 311 is always in contact with the conductive contact surface 321, improving the reliability of the electrical connection between the first conductive member 310 and the second conductive member 320.

[0095] In some possible implementation manners of the embodiments of the present application, with reference to Figure 6 and Figure 7 , the refrigerator may further include a second rotating shaft 130 and a third rotating shaft 140. Both the second rotating shaft 130 and the third rotating shaft 140 are arranged along the height direction of the box body 100. The first end of the second rotating shaft 130 can be connected to the box body 100, and the second end of the second rotating shaft 130 is rotatably connected to the door body 200 around the axis of the second rotating shaft 130 and is slidably connected to the door body 200 along a first trajectory. The first end of the third rotating shaft 140 is connected to the box body 100, and the second end of the third rotating shaft 140 is rotatably connected to the door body 200 around the axis of the third rotating shaft 140 and is slidably connected to the door body 200 along a second trajectory different from the first trajectory. Exemplarily, the first ends of the second rotating shaft 130 and the third rotating shaft 140 can both be connected to the cover plate 110. Specifically, reference can be made to the connection structure between the first end of the first rotating shaft 120 and the cover plate 110, and the embodiments of the present application will not elaborate on this again. For example Figure 6 and Figure 7 as shown, the end cover 220 of the door body 200 can be provided with a first sliding recess 222, and the extending trajectory of the first sliding recess 222 can be the first trajectory. The second end of the second rotating shaft 130 can be slidably disposed in the first sliding recess 222. The end cover 220 can further be provided with a second sliding recess 223, and the extending trajectory of the second sliding recess 223 is the second trajectory. The second end of the third rotating shaft 140 can be slidably disposed in the second sliding recess 223. The extending trajectory of the conductive contact surface 321 includes a first straight line segment B, a curve segment C, and a second straight line segment D connected in sequence. The first straight line segment B, the curve segment C, and the second straight line segment D can enclose part of the second rotating shaft 130 and part of the third rotating shaft 140.

[0096] The door body 200 is rotatably connected to the box body 100 through a second rotating shaft 130 and a third rotating shaft 140. When the door body 200 rotates relative to the box body 100, the second rotating shaft 130 slides and rotates within the second sliding recess 223, and the third rotating shaft 140 slides and rotates within the second sliding recess 223, such that the rotation trajectory of the door body 200 is a first straight line segment, a curved line segment, and a second straight line segment connected in sequence, and the first straight line segment, the curved line segment, and the third straight line segment enclose a portion of the second rotating shaft 130 and the third rotating shaft 140. With such a setting, during the process of opening and closing the door body 200, the edge of the door body 200 will not extend beyond the side surface of the box body 100, so that the refrigerator can be embedded into the cabinet body, that is, the refrigerator is an embedded refrigerator. The extending trajectory of the conductive contact surface 321 is a first straight line segment B, a curved line segment C, and a second straight line segment D connected in sequence, and the first straight line segment B, the curved line segment C, and the second straight line segment D enclose a portion of the second rotating shaft 130 and the third rotating shaft 140. The extending trajectory of the conductive contact surface 321 is the same as the rotation trajectory of the door body 200. When opening and closing the door body 200, the door body 200 can drive the second conductive member 320 to move, such that the conductive contact surface 321 slides relative to the conductive protrusion 311, and during the sliding process, the conductive protrusion 311 is always in contact with the conductive contact surface 321, improving the reliability of the electrical connection between the first conductive member 310 and the second conductive member 320.

[0097] It can be understood that the rotation trajectory of the door body 200 can also be other shapes, and the embodiments of the present application will not elaborate on this.

[0098] Reference Figure 8 , the cover plate 110 connected to the box body 100 can be provided with a second connection hole 112. The first conductive member 310 can be inserted into the second connection hole 112, and the top end of the first conductive member 310 extends out of the second connection hole 112 and is connected to the first electrical connection line. For example, the first electrical connection line can be provided with a first connection terminal, and the first connection terminal can be sleeved on the top end of the first conductive member 310. It can be understood that the top end of the first conductive member 310 and the first electrical connection line can also be connected by other means, and the embodiments of the present application will not elaborate on this. The bottom end of the second conductive member 320 can extend out of the first connection hole 111 to form a conductive protrusion 311 to abut against the conductive contact surface 321. With such a setting, the top end and the bottom end of the first conductive member 310 can be respectively arranged on the upper and lower sides of the cover plate 110, and the cover plate 110 can separate the top end and the bottom end of the first conductive member 310 to prevent the first electrical connection line from contacting the conductive contact surface 321 and causing problems such as short circuits, improving the connection reliability of the electrical connection device 300.

[0099] Exemplarily, reference Figure 9, the conductive protrusion 311 can be a bent structure that bends away from the door body 200 and abuts against the conductive contact surface 321. The bent structure endows the conductive protrusion 311 with elasticity, enabling the conductive protrusion 311 to always abut against the conductive contact surface 321, thereby improving the connection reliability between the conductive protrusion 311 and the conductive contact surface 321.

[0100] Exemplarily, the first electrical connection line can include multiple first sub-electrical connection lines. The number of the first conductive members 310 can be multiple. The multiple first conductive members 310 can be correspondingly arranged with the multiple first sub-electrical connection lines.

[0101] Exemplarily, the material of the first conductive member 310 can be brass. Brass has strong electrical conductivity and strong elasticity, which can reduce the connection resistance between the conductive protrusion 311 and the conductive contact surface 321 and increase the abutting force between the conductive protrusion 311 and the conductive contact surface 321, further improving the connection reliability between the conductive protrusion 311 and the conductive contact surface 321. It can be understood that the first conductive member 310 can also be other conductive materials, which will not be elaborated in this embodiment of the present application.

[0102] Continuing to refer to Figure 10 , the electrical connection device 300 can further include a first mounting member 330. The first mounting member 330 can be inserted into the second connection hole 112. The first mounting member 330 is provided with a third connection hole 331 for the first conductive member 310 to pass through. When installing the first conductive member 310, the first mounting member 330 can be first installed in the second connection hole 112, and then the first conductive member 310 can be inserted into the third connection hole 331. With this arrangement, the first conductive member 310 can be connected to the cover plate 110 through the first mounting member 330. When replacing and repairing the first conductive member 310, the first mounting member 330 inserted with the first conductive member 310 can be first taken out from the second connection hole 112 of the cover plate 110, and then the first conductive member 310 can be replaced and repaired. Compared with the technical solution in which the first conductive member 310 is directly inserted into the second connection hole 112 of the cover plate 110, the cover plate 110 does not need to be disassembled when replacing and repairing the first conductive member 310, improving the convenience of replacing and repairing the first conductive member 310.

[0103] Exemplarily, the material of the first mounting member 330 can be an insulating material, such as plastic, etc. The first mounting member 330 can provide insulation protection for the first conductive member 310.

[0104] Exemplarily, referring to Figure 10 and Figure 11, the first mounting member 330 may further be provided with a first receiving recess 332, the first receiving recess 332 being located on a side of the third connection hole 331 facing the top end of the first conductive member 310 and communicating with the third connection hole 331. The portion of the top end of the first conductive member 310 extending out of the third connection hole 331 may be received in the first receiving recess 332. With such a setting, it is possible to prevent the portion of the first conductive member 310 near its top end from protruding out of the first mounting member 330 and interfering with other components, and the first receiving recess 332 can also protect the first conductive member 310, improving the safety of the electrical connection device 300.

[0105] Exemplarily, referring to Figure 8 , a fourth connection hole 230 may be provided at the top end of the door body 200. Continuing to refer to Figure 12 , the first conductive member 310 may include a conductive portion 322, a bent portion 323, and a connecting portion 324 that are connected in sequence. The conductive portion 322 may extend in a direction parallel to the top end of the door body 200, and a conductive contact surface 321 may be provided on a side of the conductive portion 322 facing away from the door body 200. A part of the bent portion 323 and a part of the connecting portion 324 may be located on a side of the conductive portion 322 facing the door body 200, and this part of the bent portion 323 and this part of the connecting portion 324 may be in contact with the top end of the door body 200. The connecting portion 324 may pass through the fourth connection hole 230, and one end of the connecting portion 324 extending out of the fourth connection hole 230 may be electrically connected to the second electrical connection line. For example, the second electrical connection line may be provided with a second connection terminal, and the second connection terminal may be sleeved on one end of the connecting portion 324 facing away from the bent portion 323. It can be understood that the connecting portion 324 and the second electrical connection line may also be connected in other ways, and the embodiments of the present application will not elaborate on this.

[0106] By arranging a part of the bent portion 323 and a part of the connecting portion 324 on a side of the conductive portion 322 facing away from the door body 200, another part of the bent portion 323 is connected to the conductive portion 322. When the conductive protrusion 311 abuts against the conductive contact surface 321 of the conductive portion 322, the conductive protrusion 311 applies a downward pressure to the conductive portion 322, and another part of the bent portion 323 connected to the conductive portion 322 moves towards the door body 200, causing the bent portion 323 to be further bent and generate an upward elastic force. This elastic force causes another part of the bent portion 323 and the conductive portion 322 to move upward, so that the conductive portion 322 can abut against the conductive protrusion 311, preventing the conductive contact surface 321 from separating from the conductive protrusion 311 and improving the reliability of the electrical connection device 300.

[0107] Exemplarily, the conductive part 322, the bending part 323, and the connecting part 324 can be an integral structure. For example, the conductive part 322, the bending part 323, and the connecting part 324 can be formed by bending a strip-shaped structure with electrical conductivity. By setting it in this way, the connection strength of the conductive part 322, the bending part 323, and the connecting part 324 can be improved, the connection resistance between the conductive part 322, the bending part 323, and the connecting part 324 can be reduced, and the manufacturing difficulty of the second conductive member 320 can also be lowered.

[0108] Exemplarily, the second electrical connection line can include multiple second sub-electrical connection lines. The number of the second conductive members 320 can be multiple. The multiple second conductive members 320 can be arranged corresponding to the multiple second sub-electrical connection lines.

[0109] Exemplarily, the material of the second conductive member 320 can be brass. Brass has strong electrical conductivity and strong elasticity, which can reduce the connection resistance between the conductive protrusion 311 and the conductive contact surface 321, and increase the abutting force between the conductive protrusion 311 and the conductive contact surface 321, further improving the connection reliability between the conductive protrusion 311 and the conductive contact surface 321. It can be understood that the second conductive member 320 can also be other conductive materials, which will not be elaborated in the embodiments of the present application.

[0110] Continuing to refer to Figure 13 , the electrical connection device 300 can further include a second mounting member 340, and the second mounting member 340 can be mounted on the top end of the door body 200. For example Figure 8 as shown, the end cover 220 can be provided with a second receiving recess 240, and a part of the second mounting member 340 can be received in the second receiving recess 240. The side wall of the second receiving recess 240 can position the second mounting member 340, improving the position accuracy between the second mounting member 340 and the end cover 220. At least one guiding recess 341 can be provided on the side of the second mounting member 340 facing away from the door body 200, and the extending trajectory of the guiding recess 341 can be the same as the rotation trajectory of the door body 200. For example, the extending trajectory of the guiding recess 341 can be an arc. The guiding recess 341 is used to receive the conductive part 322. When installing the second conductive member 320, the second mounting member 340 can be first mounted on the top end of the door body 200, and then the second conductive member 320 can be mounted on the second mounting member 340.

[0111] With such a setting, the second conductive member 320 can be connected to the door body 200 through the second mounting member 340. When replacing and repairing the second conductive member 320, the second mounting member 340 connected to the second conductive member 320 can be first detached from the door body 200, and then the second conductive member 320 can be replaced and repaired. Compared with the technical solution in which the second conductive member 320 is directly connected to the door body 200, it is not necessary to disassemble the door body 200 when replacing and repairing the second conductive member 320, improving the convenience of replacing and repairing the second conductive member 320.

[0112] In addition, during the process of opening and closing the door body 200, when the conductive protrusion 311 slides on the conductive contact surface 321, the opposite side walls of the guiding recess 341 can limit and guide the conductive protrusion 311, so that the conductive protrusion 311 can slide along the extending direction of the conductive contact surface 321, preventing the conductive protrusion 311 from separating from the conductive contact surface 321 and improving the functional reliability of the electrical connection device 300.

[0113] Exemplarily, when there are multiple second conductive members 320, there can be multiple guiding recesses 341, and the multiple guiding recesses 341 can be correspondingly arranged with the multiple second conductive members 320. Each second conductive member 320 can be installed in the guiding recess 341 corresponding to it. The multiple guiding recesses 341 can be arranged at intervals on the side of the first mounting member 330 facing the cover plate 110. With such a setting, any two adjacent second conductive members 320 can be separated, preventing short circuit between two adjacent second conductive members 320. Moreover, the multiple second conductive members 320 can be arranged in the height direction perpendicular to the cabinet 100, so as to reduce the size of the electrical connection device 300 in the height direction of the cabinet 100, thereby reducing the height of the refrigerator.

[0114] Reference Figure 14 , an extension portion 342 can be provided on the side of the second mounting member 340 facing the door body 200. The extension portion 342 passes through the fourth connection hole 230, and a fifth connection hole 343 is provided in the extension portion 342. The fifth connection hole 343 communicates with the guiding recess 341, and the connection portion 324 passes through the fifth connection hole 343. By providing the extension portion 342 with the fifth connection hole 343, the connection portion 324 can pass through the fifth connection hole 343, and the extension portion 342 can protect the connection portion 324 to prevent the connection portion 324 from interfering with other components, improving the safety of the electrical connection device 300.

[0115] Exemplarily, the material of the second mounting member 340 can be an insulating material, such as plastic, etc., and the second mounting member 340 can provide insulating protection for the second conductive member 320.
