DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a hinge assembly provided in an embodiment of the present application being installed on an electrical device. Figure 2 yes Figure 1 The hinge assembly 000 may include: a hinge 100 and a protective shell 200.

[0036] The hinge 100 in the hinge assembly 000 may include: a fixed portion 101, and a rotating portion 102 fixedly connected to the fixed portion 101, the fixed portion 101 may be fixedly connected to a box in the electrical device, and the rotating portion 102 may be rotatably connected to a door body in the electrical device. In the present application, the fixed portion 101 and the rotating portion 102 in the hinge 100 may be an integral structure, and after the hinge assembly 000 is integrated into an electrical device (e.g., a refrigerator), the fixed portion 101 and the rotating portion 102 in the hinge 100 are respectively connected to the box body and the door body in the electrical device, so that the door body can rotate relative to the box body through the hinge 100, thereby realizing the opening and closing of the door body. It should be noted that the door body and the box body are not shown here, and will be described later in conjunction with the accompanying drawings.

[0037] The protective shell 200 in the hinge assembly 000 can be fixedly connected to the rotating part 102 in the hinge 100, and the protective shell 200 may include: a first shell 201 fixedly connected to one side of the rotating part 102, and a second shell 202 fixedly connected to the side of the first shell 201 away from the rotating part 102, and the first shell 201 and the second shell 202 can be used to form a wiring channel A. The wiring channel A can have a first opening a1 and a second opening a2 arranged opposite to each other, and the orientation of the first opening a1 on the wiring channel A and the orientation of the second opening a2 on the wiring channel A can be different, and the wiring channel A can be used to carry a cable, and the cable can be used to connect the power supply component in the box and the power-consuming component in the door body. For example, a display screen or an indicator light and other power-consuming components can be set on the door body, and the power supply component in the box can supply power to the power-consuming component through a cable, and the cable can be set in the wiring channel formed by the first shell and the second shell. Here, the first opening can be oriented toward the box in the electrical device, and the second opening can be oriented toward the top of the door body in the electrical device.

[0038] In the embodiment of the present application, by setting the first shell 201 and the second shell 202 in the protective shell 200, the first shell 201 is fixedly connected to the rotating part 102 in the hinge 100, and the second shell 202 is fixedly connected to one side of the first shell 201, the two shells can form a wiring channel A, and two openings in different directions connected to the wiring channel A. In this way, after the hinge assembly 000 is integrated into the electrical device, the cables in the electrical device can be placed in the wiring channel A, and one end of the cable can be extended from the first opening a1 to facilitate connection with the electrical components, and the other end of the cable can be extended from the second opening a2 to facilitate connection with the power supply components. In this way, the wiring channel A formed by the first shell 201 and the second shell 202 can effectively protect the cables, and the cables do not need to contact the hinge 100, avoiding the undesirable phenomenon of pressing or folding lines during the rotation of the door body in the electrical device relative to the box body.

[0039] In summary, an embodiment of the present application provides a hinge assembly, and the hinge assembly may include: a hinge and a protective shell. By arranging a first shell and a second shell in the protective shell, the first shell is fixedly connected to the rotating part in the hinge, and the second shell is fixedly connected to one side of the first shell, the two shells can form a wiring channel, and two openings connected to the wiring channel. In this way, after the hinge assembly is integrated into the electrical device, the cables in the electrical device can be placed in the wiring channel, and one end of the cable can extend from the first opening to be connected to the electrical component, and the other end of the cable can extend from the second opening to be connected to the power supply component. In this way, the wiring channel formed by the first shell and the second shell can effectively protect the cables, and the cables do not need to contact the hinge, thereby avoiding the undesirable phenomenon of pressing or folding lines during the rotation of the door body relative to the box body in the electrical device.

[0040] Optional, please refer to Figure 3 , Figure 3 : This is a schematic diagram of the installation of a hinge assembly and a door body provided by an embodiment of the present application. The wiring channel A formed by the first shell 201 and the second shell 202 may include: a first sub-wiring channel A1 and a second sub-wiring channel A2, the extension direction of the first sub-wiring channel A1 may be parallel to the plane where the rotating part 102 in the hinge 100 is located, and the extension direction of the second sub-wiring channel A2 may be perpendicular to the extension direction of the first sub-wiring channel A1. Among them, the end of the first sub-wiring channel A1 away from the second sub-wiring channel A2 may have a first opening a1, and the end of the second sub-wiring channel A2 away from the first sub-wiring channel A1 may have a second opening a2. In this case, by setting the first sub-wiring channel A1 and the second sub-wiring channel A2 in the wiring channel A, the first sub-wiring channel A1 is parallel to the plane where the rotating part 102 is located (for example, the XY plane in the figure), and the second sub-wiring channel A2 can be set vertically with the first sub-wiring channel A1, that is, the extension direction of the second sub-wiring channel A2 can be parallel to the Z axis. In this way, after the cables in the electrical equipment pass through the first sub-wiring channel A1, the routing direction of the cables changes and they enter the second sub-wiring channel A2, and finally extend out from the second opening a2 to be electrically connected to the electrical components on the door body, so that the wiring channel A formed by the two shells not only protects the cables, but also has a certain guiding effect on the wiring of the cables.

[0041] In the examples of this application, please refer to Figure 3 and Figure 4 , Figure 4It is an exploded schematic diagram of a partial structure of a hinge assembly and a door body provided in an embodiment of the present application. The first shell 201 in the protective shell 200 may include: a first support portion 201a and a first curved plate 201b, and the first curved plate 201b may be fixed on the side of the first support portion 201a away from the rotating portion 102. The second shell 202 in the protective shell 200 may include: a second support portion 202a and a second curved plate 202b, and the second support portion 202a may be fixedly connected to the side of the first support portion 201a away from the rotating portion 102, and the second curved plate 202b may be fixed on the side of the second support portion 202a away from the first support portion 201a. Among them, the first support portion 201a and the second support portion 202a can be used by the user to enclose a first sub-wiring channel A1, and the second curved plate 202b and the first curved plate 201b can be interlocked to form a second sub-wiring channel A2. In this case, by setting the first supporting portion 201a and the first curved plate 201b in the first shell 201, the first supporting portion 201a can be fixed to the rotating portion 102 in the hinge 100, and the first curved plate 201b is set on the side of the first supporting portion 201a away from the rotating portion 102; and the second supporting portion 202a and the second curved plate 202b are set in the second shell 202, and the second curved plate 202b is set on the side of the second supporting portion 202a away from the first supporting portion 201a, so that the first supporting portion 201a and the second supporting portion 202a are interlocked to form a first sub-wiring channel A1 and a first opening a1, and at the same time, the first curved plate 201b and the second curved plate 202b are interlocked to form a second sub-wiring channel A2 and a second opening a2, here, two sub-wiring channels can be formed by two supporting portions and two curved plates, so that the structure of the hinge assembly is relatively simple and the manufacturing cost is reduced. In addition, by placing the cables in the electrical device in the first sub-wiring channel A1 and the second sub-wiring channel A2, there will be almost no wire leakage, which ensures that the electrical device integrated with the hinge assembly 000 has a good appearance.

[0042] In this application, if Figure 4 As shown, the first support portion 201a in the first housing 201 may have a mounting groove b1 on the side away from the rotating portion 102, and the second support portion 202a may be clamped at the opening of the mounting groove b1 on the side away from the rotating portion 102. In this case, by providing the mounting groove b1 on the side of the first support portion 201a away from the rotating portion 102, the second support portion 202a may be clamped at the opening of the mounting groove b1 to form the first sub-wiring channel A1 and the first opening a1. For example, the shape of the first opening a1 may be square.

[0043] Optional, such as Figure 4As shown, the first curved plate 201b in the first shell 201 and the second curved plate 202b in the second shell 202 can both be semicircular. In this case, by setting the two curved plates to be semicircular plates, the two semicircular plates can be buckled together to form a cylindrical channel and a second opening a2, and the shape of the second opening a2 can be a circular opening. In addition, ensuring that the shapes of the two curved plates are the same can ensure that there will be no gap between the two curved plates at the joint to expose the cables, thereby improving the appearance of the hinge assembly. It should be noted that in other possible implementations, the first curved plate 201b and the second curved plate 202b can both be semi-elliptical, and the two curved plates are spliced ​​to form a cylindrical structure with an elliptical cross-section.

[0044] In the embodiments of the present application, Figure 3 and Figure 4 As shown, after the second support part 202a is clamped at the opening of the mounting groove b1 in the first support part 201a away from the rotating part 102, the side c1 of the first support part 201a away from the rotating part 102 can be flush with the side c2 of the second support part 202a away from the rotating part 102. In this case, after the second support part 202a is clamped at the opening of the mounting groove b1 in the first support part 201a, it is ensured that the sides of the two support parts away from the rotating part 102 are flush with each other. In this way, the appearance of the protective shell 200 in the hinge assembly 000 is better, and the overall thickness after the two support parts are assembled can be ensured to be small, which is convenient for the miniaturization design of the electrical equipment integrated with the hinge assembly.

[0045] Optional, such as Figure 4 As shown, the outer side surface of the second support portion 202a in the second shell 200 may have a first clip B1, and the inner side wall of the mounting groove b1 in the first support portion 201a may have a second clip B2 that matches the first clip B1. In this case, by setting a plurality of first clips B1 on the outer side surface of the second support portion 202a, and setting a plurality of second clips B2 that correspond to the plurality of first clips B1 on the inner side wall of the mounting groove b1 in the first support portion 201a, the two shells are fixedly connected by the clamping of two corresponding clips. When the cable needs to be replaced or repaired, the first clip B1 and the second clip B2 are separated, and the second shell 202 can be removed from the first shell 201, which is convenient for the operator to install and improves the user experience. For example, the first clamping member B1 disposed on the outer side of the second support portion 202a may be a clamping protrusion, and the second clamping member B2 disposed in the mounting groove b1 in the first support portion 201a may be a clamping groove matched with the clamping protrusion.

[0046] In the embodiments of the present application, Figure 3 and Figure 4As shown, the central axis of the second sub-wiring channel A2 in the wiring channel A can coincide with the rotation axis centerline of the door body 01 in the electrical device 00 relative to the rotating part 102. In this case, by setting the central axis of the second sub-wiring channel A2 in the wiring channel A to coincide with the rotation axis centerline of the door body 01 relative to the rotating part 102, after the hinge assembly 000 is integrated into the electrical device 00, during the process of the door body 01 rotating relative to the box body 02 through the rotating part 102, the cable 03 extending from the second opening a2 only rotates with the door body 01, and no telescopic movement occurs, thereby ensuring the connection stability of the cable 03 with the power supply components and the power-consuming components (not shown in the figure). For example, during the process of opening the door body 01, the cable extending from the second opening a2 only rotates with the door body 01, and no stretching occurs. For examples, please refer to Figure 5 , Figure 5 1 is a partial exploded schematic diagram of another hinge assembly and electrical device provided in an embodiment of the present application. The rotating part 102 in the hinge 100 may have a rotating shaft 102a on the side away from the protective shell 200, and the door body 01 in the electrical device 00 may have a connecting hole d1, and the rotating shaft 102a may be rotatably connected to the connecting hole d1.

[0047] Optional, please refer to Figure 6 , Figure 6 It is a schematic diagram of a connection between a limiter and a cable provided in an embodiment of the present application. The wiring channel A formed by the first shell 201 and the second shell 202 may have a plurality of limiters C arranged in an array, and the arrangement direction of the plurality of limiters C may be parallel to the extension direction of the wiring channel A, and the plurality of limiters C may be used to engage with the cable 03 located in the wiring channel A. In this case, by setting a plurality of limiters C in the wiring channel A, the plurality of limiters C may be used to engage with the cable 03 located in the wiring channel A to achieve a limiting effect on this part of the cable, so that the cable will not move at will, and further ensure the connection stability between the cable and the power supply component and the power-consuming component. For example, the limiter C may be a clamping ring, and the cable located in the wiring channel may be arranged in a cavity formed by a plurality of clamping rings. It should be noted that in the present application, a plurality of limiters C may be arranged on the side of the second shell 202 facing the first shell 201.

[0048] In summary, an embodiment of the present application provides a hinge assembly, and the hinge assembly may include: a hinge and a protective shell. By arranging a first shell and a second shell in the protective shell, the first shell is fixedly connected to the rotating part in the hinge, and the second shell is fixedly connected to one side of the first shell, the two shells can form a wiring channel, and two openings connected to the wiring channel. In this way, after the hinge assembly is integrated into the electrical device, the cables in the electrical device can be placed in the wiring channel, and one end of the cable can extend from the first opening to be connected to the electrical component, and the other end of the cable can extend from the second opening to be connected to the power supply component. In this way, the wiring channel formed by the first shell and the second shell can effectively protect the cables, and the cables do not need to contact the hinge, thereby avoiding the undesirable phenomenon of pressing or folding lines during the rotation of the door body relative to the box body in the electrical device.

[0049] The present application also provides an electrical appliance, which may be a refrigerator, an oven with an integrated hinge, or other electrical appliances. Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the external structure of an electrical device provided in an embodiment of the present application, Figure 8 yes Figure 7 The exploded schematic diagram of the partial structure of the electrical device shown. The electrical device 00 may include: a box 02, a door 01 and a hinge assembly 000, the hinge assembly 000 may be used to connect the box 02 and the door 01, and the hinge assembly 000 may be any of the hinge assemblies given above. In this way, by arranging a first shell and a second shell in the protective shell of the hinge assembly, the first shell is fixedly connected to the rotating part in the hinge, and the second shell is fixedly connected to one side of the first shell, the two shells can form a wiring channel, and two openings connected to the wiring channel. In this way, after the hinge assembly is integrated into the electrical device, the cable in the electrical device can be placed in the wiring channel, and one end of the cable can extend from the first opening to connect with the electrical component, and the other end of the cable can extend from the second opening to connect with the power supply component. In this way, the wiring channel formed by the first shell and the second shell can effectively protect the cable, and the cable does not need to contact the hinge, avoiding the undesirable phenomenon of pressing or folding lines during the rotation of the door body in the electrical device relative to the box.

[0050] In the examples of this application, please refer to Figure 8 and Fig. 9 , Fig. 9It is a cross-sectional view of an electrical device provided in an embodiment of the present application. The door body 01 in the electrical device 00 may have a groove body 01a, and the electrical device 00 may also include: a door body cover plate 04 covering the groove body 01a, and the cable 03 may be located in the groove body 01a after extending from the second opening a2 of the wiring channel A, and the door body cover plate 04 may cover this part of the cable. In the present application, the door body cover plate 04 may also cover the second sub-wiring channel A2, and in the direction perpendicular to the rotating part 102 (for example, the Z-axis direction), the distance e1 between the opening surface of the second opening a2 of the wiring channel A and the rotating part 102 may be greater than the minimum distance e2 between the door body cover plate 04 and the rotating part 102. In this way, during the rotation of the door body 01, the undesirable phenomenon of wire clamping and wire pressing between the door body cover plate 04 and the protective shell 200 can be effectively prevented. For example, when the first housing 201 includes the first curved plate 201b and the first supporting portion 201a, and the second housing 202 includes the second curved plate 202b and the second supporting portion 202a, the side of the first curved plate 201b away from the first supporting portion 201a and the side of the second curved plate 202b away from the second supporting portion 202a are flush with each other. The side of the first curved plate 201b away from the first supporting portion 201a and the side of the second curved plate 202b away from the second supporting portion 202a can be buckled to form a second opening a2.
