Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. The cabinet and door of a current refrigerator are usually connected by hinges. For non-embedded refrigerators, the cabinet and door are usually connected by a single-axis hinge, and for embedded refrigerators, the cabinet and door are usually connected by a double-axis hinge.

[0003] Whether it is a non-embedded refrigerator or an embedded refrigerator, the connection line connecting the cabinet and the door body is usually connected to the cabinet at one end, and the other end passes through the through hole on the rotating shaft of the hinge and extends into the door body to be connected to the door body.

[0004] With this type of connection, during the opening and closing of the door, the part of the connecting wire connected to the door body will rotate with the door body, while the part connected to the cabinet will not rotate with the door body, which will cause the connecting wire to be pulled and twisted. Especially for built-in refrigerators, the rotation center of the hinge is not fixed during the opening and closing of the door, which will cause the connecting wire to fall off or break, thereby affecting the normal use of the refrigerator. Summary of the invention

[0005] The embodiment of the present invention provides a refrigerator, which solves the problem in the prior art that the connection line between the refrigerator body and the door body is easy to fall off or break, thus affecting the normal use of the refrigerator.

[0006] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0007] According to a first aspect of the present application, there is provided a refrigerator, comprising a cabinet, a door and a hinge assembly, wherein a storage cavity with an opening on one side is formed in the cabinet; the door is arranged at the opening of the storage cavity and can rotate relative to the cabinet to open or close the opening of the storage cavity; the hinge assembly comprises a first fixing member and a second fixing member, the first fixing member is fixedly connected to one of the cabinet and the door, the second fixing member is fixedly connected to the other of the cabinet and the door, and the first fixing member is rotatably connected to the second fixing member so that the door can rotate relative to the cabinet; wherein the first fixing member has a first conductive part, which is electrically connected to a connecting line of one of the cabinet and the door; the second fixing member has a second conductive part, which is electrically connected to a connecting line of the other of the cabinet and the door, and the first conductive part is in contact with and electrically connected to the second conductive part.

[0008] The refrigerator provided in the present application is fixedly connected to one of the box body and the door body by a first fixing member, and the second fixing member is fixedly connected to the other of the box body and the door body. The first fixing member is rotatably connected to the second fixing member, so that the door body can be rotated relative to the box body, thereby allowing the door body to open or close the opening of the storage cavity.

[0009] The door body rotates relative to the casing, which can drive the first fixing part and the second fixing part to rotate relative to each other. In this process, since the first conductive part is electrically connected to the connecting line of one of the casing and the door body, and the second conductive part is electrically connected to the connecting line of the other of the casing and the door body, the first conductive part is in contact with and electrically connected to the second conductive part. Therefore, the current of the connecting line of the casing can be transmitted to the connecting line of the door body through the first conductive part and the second conductive part. Moreover, the connecting line in the door body will rotate synchronously with the rotation of the door body. At the same time, the first conductive part rotates relative to the second conductive part, thereby avoiding twisting and pulling of the connecting line in the casing, thereby avoiding the connecting line from falling off or breaking, and ensuring the normal use of the refrigerator.

[0014] In some embodiments, there are multiple first conductive parts and multiple second conductive parts, and the first conductive parts of the multiple first conductive parts are arranged at intervals along the extension direction of the mounting hole, and the second conductive part of a second conductive part corresponds to the first conductive part of a first conductive part; a hinge assembly can be used to realize the connection between the connecting wires of multiple box bodies and the connecting wires of multiple door bodies to improve the protection effect of the connecting wires.

[0015] In some embodiments, the plurality of first conductive members are fixed on the inner circumferential wall of the mounting hole and are arranged at intervals along the circumference of the mounting hole; this arrangement facilitates the selection and processing of the first conductive members and the second conductive members.

[0016] In some embodiments, the first fixing member also has a first fixing portion, which is fixedly connected to one of the casing and the door body, and the mounting hole is formed on the first fixing portion. The first fixing portion is provided with a first terminal, and the first terminal is electrically connected to an end of the first conductive column away from the first conductive column; and / or, the second fixing member also includes a second fixing portion, which is fixedly connected to the other of the casing and the door body, and is connected to an end of the second conductive column away from the second conductive column, and the second fixing portion is provided with a second terminal, and the second terminal is electrically connected to an end of the second conductive column away from the second conductive column. The provision of the first terminal and the second terminal can facilitate the wiring of the connecting wires, thereby improving the assembly efficiency of the refrigerator.

[0045] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0049] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0050] The electrical components on the door of the refrigerator usually need to be connected to the electrical system inside the cabinet through connecting wires, so that after the external power supply of the electrical system inside the cabinet is powered on, the electrical components on the door can be powered on to enable the electrical components on the door to work normally.

[0051] For traditional refrigerators, the cabinet and the door are usually connected by a single-axis hinge so that the door can be opened and closed by the hinge, and one end of the connecting line connecting the electrical system in the cabinet and the electrical components on the door is connected to the cabinet, and the other end passes through the through hole in the rotating shaft of the hinge and extends into the door.

[0052] During the process of opening and closing the door, the part of the connecting wire extending into the door will rotate with the rotation of the door, while the part of the connecting wire located inside the box will not rotate, which will cause the connecting wire to be pulled and twisted with the rotation of the door. As a result, the connecting wire will suffer from fatigue and breakage after multiple pulling and twisting, thus affecting the normal use of the refrigerator.

[0053] For built-in refrigerators, in order to avoid interference between the refrigerator door and the cabinet, the door and the cabinet are usually connected by a double-axis hinge. In the current built-in refrigerators, the connecting line connecting the cabinet and the door is also connected to the cabinet at one end, and the other end passes through the through hole in the hinge shaft and extends into the door.

[0054] Since the hinges of built-in refrigerators are double-axis hinges, the rotating axis of the door body is not fixed during the opening and closing process of the door body, so the pulling and twisting of the connecting wires are more serious. Long-term pulling and twisting of the connecting wires will cause fatigue damage and falling off of the connecting wires, thus affecting the normal use of the refrigerator.

[0055] Based on this, the present application provides a refrigerator, such as Figure 1 As shown, the refrigerator comprises a box body 1, a door body 2 and a hinge assembly 3. A storage cavity 11 with an opening on one side is formed in the box body 1, and the storage cavity 11 is used to place food.

[0056] The storage cavity 11 can be divided into a plurality of storage compartments to facilitate classified storage of different foods, and the temperatures of different storage compartments can be controlled so that the foods in different storage compartments have a more suitable storage temperature.

[0057] The door body 2 is disposed at the opening of the storage cavity 11 and can rotate relative to the box body 1 to open or close the opening of the storage cavity 11. When the door body 2 opens the opening of the storage cavity 11, food can be placed in the storage cavity 11 or taken out from the storage cavity 11; when the door body 2 closes the opening of the storage cavity 11, the storage cavity 11 can be sealed to maintain the temperature in the storage cavity 11, thereby better storing the food in the storage cavity 11.

[0058] The hinge assembly 3 is connected between the cabinet 1 and the door 2, and is used to make the door 2 rotate relative to the cabinet 1. The hinge assembly 3 is usually arranged on the refrigerator along its width direction (such as Figure 1 One side in the middle direction X) of the refrigerator is provided to facilitate users to open and close the door body 2 and to facilitate users to take food from the storage cavity 11; and, in order to facilitate the installation of the hinge assembly 3, the hinge assembly 3 is usually arranged at the upper end and / or the lower end of the refrigerator.

[0059] Specifically, Figure 2 As shown, the hinge assembly 3 includes a first fixing member 31 and a second fixing member 32 .

[0060] The first fixing member 31 is fixedly connected to one of the box body 1 and the door body 2, and the second fixing member 32 is fixedly connected to the other of the box body 1 and the door body 2. That is, if the first fixing member 31 is fixedly connected to the box body 1, the second fixing member 32 is fixedly connected to the door body 2; if the first fixing member 31 is fixedly connected to the door body 2, the second fixing member 32 is fixedly connected to the box body 1.

[0061] Here, the first fixing member 31 is fixedly connected to the door body 2, and the second fixing member 32 is fixedly connected to the box body 1. The first fixing member 31 is rotatably connected to the second fixing member 32. When the door body 2 is opened or closed, the door body 2 drives the first fixing member 31 to rotate relative to the second fixing member 32, so that the door body 2 can rotate relative to the box body 1, so that the door body 2 can be opened and closed smoothly.

[0062] For example, Figure 3 As shown, the first fixing member 31 includes a first fixing plate 311 and a bearing 312. The first fixing plate 311 is fixedly connected to the door body 2. The bearing 312 is fixed on the first fixing plate 311, and the axial direction of the bearing 312 is aligned with the height direction of the refrigerator (such as Figure 1 The second fixing member 32 includes a second fixing plate 321 and a rotating shaft 322, the second fixing plate 321 is fixed on the box body 1, the rotating shaft 322 is fixed on the second fixing plate 321, and the axial direction of the rotating shaft 322 is consistent with the height direction of the refrigerator.

[0063] One end of the rotating shaft 322 is connected to the bearing 312 , so that the first fixing member 31 and the fixing member are rotatably connected through the cooperation between the rotating shaft 322 and the bearing 312 .

[0064] For example, Figure 4 As shown, the hinge assembly 3 is arranged at the upper end of the refrigerator, and the first fixing member 31 has a first fixing portion 313, which is fixed to the upper end of the door body 2. The first fixing portion 313 is formed with a mounting hole 3131 extending along the height direction of the refrigerator.

[0065] The second fixing member 32 has a second fixing portion 323 and a rotating portion 324. The second fixing portion 323 is fixed to the upper end of the box body 1, and the rotating portion 324 is fixed to the lower side of the fixing portion. At least part of the rotating portion 324 extends into the mounting hole 3131 and rotates in the mounting hole 3131, thereby realizing the rotational connection between the first fixing member 31 and the second fixing member 32.

[0066] On this basis, in order to prevent the first fixing member 31 and the second fixing member 32 from rotating relative to each other, causing the connection line between the box body 1 and the door body 2 to be twisted and pulled. Figure 5As shown, the first fixing member 31 has a first conductive portion 314, which is electrically connected to the connecting line of one of the box body 1 and the door body 2; the second fixing member 32 has a second conductive portion 325, which is electrically connected to the connecting line of the other of the box body 1 and the door body 2, and the first conductive portion 314 is in contact with and electrically connected to the second conductive portion 325.

[0067] That is, when the first fixing member 31 is connected to the box body 1 and the second fixing member 32 is connected to the door body 2, the first conductive part 314 is electrically connected to the connection line of the box body 1, and the second conductive part 325 is electrically connected to the connection line of the door body 2. When the first fixing member 31 is connected to the door body 2 and the second fixing member 32 is connected to the box body 1, the first conductive part 314 is electrically connected to the connection line of the door body 2, and the second conductive part 325 is electrically connected to the connection line of the box body 1.

[0068] It should be noted that the connecting wires of the door body 2 are wires or signal wires disposed inside the door body 2 and are used to connect to electrical equipment on the door body 2 , and the connecting wires of the box body 1 are wires or signal wires disposed inside the box body 1 and are used to connect to the electrical system inside the box body 1 .

[0069] Here, the first fixing member 31 is connected to the door body 2, and the second fixing member 32 is connected to the box body 1. Through the arrangement of the first conductive part 314 and the second conductive part 325, during the opening and closing of the door body 2, the first fixing member 31 can be driven to rotate relative to the second fixing member 32, thereby driving the first conductive part 314 to rotate with the first fixing member 31, so that the first conductive part 314 moves relative to the second conductive part 325.

[0070] Moreover, during this process, the connecting wire of the box body 1 can transmit current to the second conductive part 325 connected thereto, and from the second conductive part 325 to the first conductive part 314, and then from the first conductive part 314 to the connecting wire of the door body 2, so as to realize the electrical connection between the connecting wire of the box body 1 and the connecting wire of the door body 2.

[0071] Since the connecting wires of the door body 2 are not directly connected to the connecting wires of the box body 1 during the opening and closing of the door body 2, and the first conductive part 314 moves relative to the second conductive part 325, the connecting wires of the door body 2 will not cause twisting and pulling on the connecting wires in the box body 1 during the synchronous rotation of the door body 2, thereby avoiding fatigue damage or falling off of the connecting wires due to multiple openings and closings of the door body 2, thereby ensuring the normal use of the refrigerator.

[0072] Exemplarily, the first fixing member 31 is fixedly connected to the door body 2, the second fixing member 32 is fixedly connected to the box body 1, and the first fixing member 31 and the second fixing member 32 are rotatably connected via the rotating shaft 322 and the bearing 312.

[0073] like Figure 5 As shown, the first conductive part 314 is fixed on the first fixing plate 311 , and the second conductive part 325 is fixed on the peripheral wall of the rotating shaft 322 or fixed on the second fixing plate 321 through a connecting rod. The first conductive part 314 is in contact with the second conductive part 325 and is electrically connected.

[0074] When the door 2 of the refrigerator is opened and closed, the first fixing plate 311 is driven to rotate relative to the rotating shaft 322 , thereby driving the first conductive part 314 to rotate along with the first fixing plate 311 , so that the first conductive part 314 can move relative to the second conductive part 325 .

[0075] It should be noted that the first conductive part 314 can be a block-shaped conductor made of conductive metal such as iron, copper, or a strip-shaped conductor extending circumferentially along the rotating shaft 322, and the second conductive part 325 can be a sheet-shaped or long strip-shaped conductor made of metal such as iron, copper, etc., so that during the movement of the first conductive part 314 relative to the second conductive part 325, the first conductive part 314 and the second conductive part 325 can always be in contact and conduct electricity.

[0076] The first conductive part 314 can be directly electrically connected to the connection line of the door body 2 , or a conductive column can be provided on the first conductive part 314 and the connection line of the door body 2 can be electrically connected to the conductive column.

[0077] The second conductive part 325 can be directly electrically connected to the connecting wire of the box 1 , or a conductive column can be provided on the second conductive part 325 and the connecting wire of the box 1 can be electrically connected to the conductive column.

[0078] Exemplarily, the first fixing member 31 is fixedly connected to the door body 2, the second fixing member 32 is fixedly connected to the box body 1, and the first fixing member 31 and the second fixing member 32 are rotatably connected through the mounting hole 3131 and the rotating part 324.

[0079] In some embodiments, Figure 6 As shown, the rotating portion 324 may be a rotating shaft 326 , the mounting hole 3131 may be a blind hole opening toward the second fixing member 32 , the rotating shaft 326 extends into the mounting hole 3131 , and is rotatably connected to the mounting hole 3131 .

[0080] At this time, if Figure 7As shown, the first conductive part 314 can be arranged at the bottom of the mounting hole 3131, and the second conductive part 325 can be arranged at the bottom of the rotating shaft 326. During the opening and closing process of the door body 2, the first fixed part 313 will be driven to rotate synchronously with the door body 2, so that the rotating shaft 326 rotates in the mounting hole 3131, thereby driving the first conductive part 314 to rotate relative to the second conductive part 325.

[0081] In addition, if Figure 8 As shown, the first conductive portion 314 may also be disposed on the inner circumferential wall of the mounting hole 3131 , and / or the second conductive portion 325 may be disposed on the circumferential wall of the rotating shaft 326 .

[0082] In addition, if Fig. 9 As shown, the first conductive portion 314 may also be disposed on the upper side of the first fixing portion 313 , and the second conductive portion 325 is disposed on the peripheral wall of the rotating shaft 326 and is located outside the mounting hole 3131 .

[0083] It should be noted that the first conductive part 314 can be a block-shaped conductor made of conductive metal such as iron, copper, or a strip-shaped conductor extending circumferentially along the rotating shaft 322, and the second conductive part 325 can be a sheet-shaped or long strip-shaped conductor made of metal such as iron, copper, etc., so that during the movement of the first conductive part 314 relative to the second conductive part 325, the first conductive part 314 and the second conductive part 325 can always be in contact and conduct electricity.

[0084] The first conductive part 314 can be directly electrically connected to the connection line of the door body 2 , or a conductive column can be provided on the first conductive part 314 and the connection line of the door body 2 can be electrically connected to the conductive column.

[0085] The second conductive part 325 can be directly electrically connected to the connecting wire of the box 1 , or a conductive column can be provided on the second conductive part 325 and the connecting wire of the box 1 can be electrically connected to the conductive column.

[0086] In other embodiments, Fig.10 As shown, the rotating portion 324 may be the second conductive portion 325, that is, the rotating portion 324 and the second conductive portion 325 are the same component. At this time, at least a portion of the second conductive portion 325 extends into the mounting hole 3131 and can rotate in the mounting hole 3131, so that the first fixing member 31 and the second fixing member 32 are rotatably connected through the rotatable connection between the second conductive portion 325 and the mounting hole 3131.

[0087] By directly rotatably connecting the second conductive portion 325 to the mounting hole 3131 , it is possible to avoid separately arranging the second conductive portion 325 on the rotating portion 324 , thereby simplifying the structure of the second fixing member 32 and facilitating the processing and manufacturing of the second fixing member 32 .

[0088] On this basis, in order to avoid the phenomenon of poor contact between the first conductive part 314 and the second conductive part 325 when the first conductive part 314 rotates relative to the second conductive part 325, the first conductive part 314 can have a first conductive arc surface 3141 extending along the circumference of the mounting hole 3131, and the second conductive part 325 can be in contact with the first conductive arc surface 3141; and / or the second conductive part 325 can have a second conductive arc surface 3251 extending along the circumference of the mounting hole 3131, and the first conductive part 314 can be in contact with the second conductive arc surface 3251.

[0089] For example, Fig.10 As shown, the second conductive part 325 can be a rotating shaft 326 made of conductive metal, and the first conductive part 314 can be an inner peripheral wall of the mounting hole 3131, and the inner peripheral wall of the mounting hole 3131 is made of conductive metal. When the first conductive part 314 rotates relative to the second conductive part 325, the peripheral wall of the second conductive part 325 contacts the inner peripheral wall of the mounting hole 3131, thereby achieving current transmission between the first conductive part 314 and the second conductive part 325.

[0090] At this time, the first conductive arc surface 3141 is the inner wall surface of the mounting hole 3131, and the second conductive arc surface 3251 is the outer wall surface of the rotating shaft 326. Through the contact between the first conductive arc surface 3141 and the second conductive arc surface 3251, the contact area between the first conductive part 314 and the second conductive part 325 can be increased, thereby ensuring that the first conductive part 314 and the second conductive part 325 can effectively contact each other to improve the conductivity of the two.

[0091] For example, Fig.11 As shown, the first conductive part 314 includes a first conductive member 3142 and a first conductive column 3143. The first conductive member 3142 is fixed in the mounting hole 3131. One end of the first conductive column 3143 is electrically connected to the first conductive member 3142, and the other end of the first conductive column 3143 is electrically connected to the connection line of one of the box body 1 or the door body 2. Here, taking the first fixing member 31 fixed to the door body 2 as an example, the other end of the first conductive column 3143 is electrically connected to the connection line of the door body 2.

[0092] By connecting the connecting wire between the first conductive member 3142 and the door body 2 through the first conductive column 3143, it is possible to avoid extending the connecting wire into the mounting hole 3131 to connect with the first conductive member 3142, thereby reducing the difficulty of wiring and simplifying the operation.

[0093] Furthermore, the first conductive column 3143 has a relatively high hardness and will not bend or entangle around other components in the mounting hole 3131 during the rotation of the door body 2 , thereby being able to protect the connection wires of the door body 2 .

[0094] In addition, the provision of the first conductive column 3143 can also avoid making the first conductive member 3142 larger, thereby saving materials and reducing costs.

[0095] The first conductive member 3142 may extend along the circumferential direction of the mounting hole 3131 , and the inner circumferential wall surface of the first conductive member 3142 is the first conductive arc surface 3141 .

[0096] At this time, if Fig.12 As shown, the second conductive part 325 contacts the first conductive member 3142, that is, the second conductive part 325 contacts the first conductive arc surface 3141 of the first conductive member 3142. Specifically, the second conductive part 325 may include a fixed shaft 3252 and a conductive sheet 3253, one end of the fixed shaft 3252 is fixedly connected to the second fixed part 323, and the other end of the fixed shaft 3252 extends into the mounting hole 3131 and is rotatably connected to the bottom wall of the mounting hole 3131; the conductive sheet 3253 is fixed on the peripheral wall of the fixed shaft 3252, and the conductive sheet 3253 contacts the first conductive arc surface 3141 of the first conductive part 314.

[0097] By making the conductive sheet 3253 contact the first conductive arc surface 3141 , even when the first conductive part 314 and the second conductive part 325 shake up and down, the conductive sheet 3253 can be in contact with the first conductive arc surface 3141 , thereby ensuring that the first conductive part 314 and the second conductive part 325 are in contact, thereby improving the conductivity of the two.

[0098] It should be noted that the first conductive member 3142 may be in a ring shape, an arc shape, an irregular shape, etc. The first conductive member 3142 may be a conductive block made of conductive metal such as copper or iron, or may be a carbon brush 3144 .

[0099] Preferably, the first conductive member 3142 is a carbon brush 3144. The carbon brush 3144 is a sliding contact member commonly used in electrical equipment, has good conductivity, is relatively easy to obtain, and can reduce manufacturing costs.

[0100] In addition, the carbon brush 3144 has a smaller friction force when in contact with the conductive metal, so that the first conductive part 3142 and the second conductive part 325 can move relatively smoothly, thereby better avoiding the phenomenon of pulling and twisting of the connecting line between the cabinet 1 and the door body 2 during the opening and closing of the refrigerator.

[0101] In some embodiments, Fig.13As shown, the second conductive portion 325 includes a second conductive member 3254 and a second conductive column 3255. Fig.14 As shown, the second conductive member 3254 is located in the mounting hole 3131, and the second conductive member 3254 is in contact with and electrically connected to the first conductive member 3142; one end of the second conductive column 3255 is electrically connected to the second conductive member 3254, and the other end of the second conductive column 3255 is electrically connected to the connecting line of the other one of the box body 1 and the door body 2.

[0102] Here, taking the example that the first fixing member 31 is fixed on the door body 2 and the second fixing member 32 is fixed on the box body 1 , the other end of the second conductive column 3255 is electrically connected to the connecting wire of the box body 1 .

[0103] By connecting the connecting wire between the second conductive member 3254 and the box body 1 through the second conductive column 3255, it is possible to avoid extending the connecting wire into the mounting hole 3131 to connect with the second conductive member 3254, thereby reducing the difficulty of wiring and simplifying the operation.

[0104] Furthermore, the provision of the second conductive column 3255 can also avoid making the second conductive member 3254 larger, thereby saving materials and reducing costs.

[0105] It should be noted that, in order to enable the second conductive part 325 to rotate in the mounting hole 3131, thereby realizing the rotational connection between the second fixing member 32 and the first fixing member 31, the second conductive member 3254 can be set to be circular, annular or arc-shaped. In addition, the second conductive member 3254 can be a conductive block made of conductive metal such as copper and iron, or a conductive slip ring 3256.

[0106] Preferably, the second conductive member 3254 is a conductive slip ring 3256. The conductive slip ring 3256 is a rotating conductive device commonly used in electrical equipment and has good conductive performance and wear resistance.

[0107] The conductive slip ring 3256 is relatively easy to obtain, which can reduce the manufacturing cost. In addition, the conductive slip ring 3256 can improve the system performance, simplify the system structure, and prevent the connecting wire from being twisted during the rotation process.

[0108] Here, the current transmission between the connecting wire of the box body 1 and the connecting wire of the door body 2 is realized by taking the conductive slip ring 3256 and the carbon brush 3144 as an example for explanation.

[0109] Specifically, in some embodiments, Fig.15As shown, the carbon brush 3144 is fixed on the inner wall of the mounting hole 3131, and the carbon brush 3144 is electrically connected to the connecting line of the door body 2 through the first conductive column 3143, the conductive slip ring 3256 is located in the mounting hole 3131, and the outer wall of the conductive slip ring 3256 is in contact with the carbon brush 3144, and the conductive slip ring 3256 is electrically connected to the connecting line of the box body 1 through the second conductive column 3255.

[0110] During the process of opening or closing the door body 2, the carbon brush 3144 can be driven to rotate synchronously with the door body 2, so that the conductive slip ring 3256 rotates in the mounting hole 3131, so that the conductive slip ring 3256 and the carbon brush 3144 rotate relative to each other. In addition, during the relative rotation of the conductive slip ring 3256 and the carbon brush 3144, the conductive slip ring 3256 and the carbon brush 3144 can always be in contact with each other, so that the connecting wire of the box body 1 can transmit the current to the conductive slip ring 3256, and then transmit the current from the conductive slip ring 3256 to the carbon brush 3144, and then transmit the current to the connecting wire of the door body 2 through the carbon brush 3144.

[0111] In other embodiments, Fig.16 As shown, the carbon brush 3144 is fixed in the mounting hole 3131 and has a gap with the inner circumferential wall of the mounting hole 3131. The conductive slip ring 3256 is located in the mounting hole 3131, and the outer circumferential wall of the conductive slip ring 3256 is slidably connected to the inner circumferential wall of the mounting hole 3131. The inner circumferential wall of the conductive slip ring 3256 contacts the carbon brush 3144.

[0112] When the door body 2 is opened or closed, the carbon brush 3144 and the first fixing member 31 can be driven to rotate synchronously with the door body 2, so that the conductive slip ring 3256 rotates between the inner peripheral wall of the mounting hole 3131 and the carbon brush 3144. During the rotation of the conductive slip ring 3256, the conductive slip ring 3256 and the carbon brush 3144 can always be in contact, so that the connecting wire of the box body 1 can transmit current to the conductive slip ring 3256, and then from the conductive slip ring 3256 to the carbon brush 3144, and then transmitted to the connecting wire of the door body 2 through the carbon brush 3144.

[0113] The relative sliding and electrical connection between the carbon brush 3144 and the conductive slip ring 3256 can prevent the connection wires of the box body 1 and the door body 2 from twisting and pulling during the opening and closing of the door body 2, thereby preventing damage to the connection wires. In addition, when the carbon brush 3144 and the conductive slip ring 3256 rotate relative to each other, the friction between the two is small, which enables the two to rotate relative to each other smoothly, thereby better protecting the connection wires.

[0114] In some embodiments, Fig.17As shown, there are multiple first conductive parts 314 , and the first conductive members 3142 of the multiple first conductive parts 314 are arranged at intervals along the extension direction of the mounting hole 3131 , and one first conductive member 3142 is connected to the connecting line of the door body 2 through a first conductive column 3143 .

[0115] like Fig.18 As shown, the number of the second conductive parts 325 is also multiple, and the second conductive member 3254 of one second conductive part 325 is electrically connected to the connecting line of the box body 1 through one second conductive column 3255. Fig.19 As shown, the second conductive element 3254 of one second conductive portion 325 corresponds to the first conductive element 3142 of one first conductive portion 314 , and one second conductive element 3254 contacts and is electrically connected to one first conductive element 3142 .

[0116] By providing a plurality of first conductive parts 314 and a plurality of second conductive parts 325, it is possible to connect a plurality of connecting wires of the box bodies 1 and a plurality of connecting wires of the door bodies 2 respectively through the carbon brushes 3144 and the conductive slip rings 3256, thereby avoiding as much as possible the twisting and pulling of the connecting wires of the box bodies 1 and the connecting wires of the door bodies 2 due to the rotation of the door body 2.

[0117] The plurality of first conductive members 3142 are spaced apart along the extension direction of the mounting hole 3131 , which can avoid conduction between adjacent conductive slip rings 3256 or adjacent carbon brushes 3144 and facilitate the arrangement of the plurality of first conductive parts 314 and the plurality of second conductive parts 325 .

[0118] On this basis, the plurality of first conductive members 3142 can be fixed on the inner circumferential wall of the mounting hole 3131, and the plurality of first conductive members 3142 can be arranged at intervals along the circumferential direction of the mounting hole 3131. In this way, the plurality of first conductive members 3142 can be made to have the same size, and the plurality of second conductive members 3254 can be made to have the same size, thereby facilitating the selection and processing of the first conductive members 3142 and the second conductive members 3254.

[0119] Furthermore, by staggering the plurality of first conductive members 3142 in the circumferential direction of the mounting hole 3131 , interference between the first conductive columns 3143 can be avoided more easily when arranging the plurality of first conductive columns 3143 , thereby facilitating the arrangement and layout of the first conductive columns 3143 .

[0120] In some embodiments, this is to facilitate the connection between the connecting wire and the first conductive pillar 3143 , and to facilitate the connection between the connecting wire and the second conductive pillar 3255 .

[0121] like Fig. 20As shown, a first terminal 3132 may be provided on the first fixing portion 313. Specifically, the first terminal 3132 is provided on a side of the first fixing portion 313 away from the second fixing member 32; the first terminal 3132 is electrically connected to an end of the first conductive column 3143 away from the first conductive member 3142.

[0122] And / or, a second terminal 3231 is provided on the second fixing portion 323 . Specifically, the second terminal 3231 is provided on a side of the second fixing portion 323 away from the second conductive member 3254 ; the second terminal 3231 is electrically connected to an end of the second conductive member 3255 away from the second conductive member 3254 .

[0123] Taking the hinge assembly 3 as an example, in which the hinge assembly 3 is disposed at the upper end of the refrigerator, the first fixing member 31 is fixedly connected to the door body 2, and the second fixing member 32 is fixedly connected to the box body 1, the second fixing portion 323 is located above the first fixing member 31 and is fixed to the box body 1. The second conductive member 3254 is located in the mounting hole 3131, one end of the second conductive column 3255 is connected to the second conductive member 3254, the second fixing portion 323 is connected to one end of the second conductive column 3255 away from the second conductive member 3254, and the second conductive member 3254 is supported and fixed by the second conductive column 3255.

[0124] By setting the first terminal 3132 and the second terminal 3231, when the connecting wire of the door body 2 is connected to the first terminal 3132, the connection between the connecting wire of the door body 2 and the first conductive member 3142 can be realized, and when the connecting wire of the box body 1 is connected to the second terminal 3231, the connection between the connecting wire of the box body 1 and the second conductive member 3254 can be realized, so that the connecting wire can be connected more conveniently.

[0125] The number of the first terminals 3132 and the number of the second terminals 3231 can be set according to actual needs, and specifically, can be set according to the number of connecting wires of the cabinet 1 and the number of connecting wires of the door body 2 that need to be connected.
