It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.

With the improvement of life quality of people, more demands are put forward on the functions of household appliances. For example, the door body of the existing refrigerator is not simply used to open or close the opening of the refrigerator body, but is given more functions. People can know information such as temperature in the refrigerator and conditions of food materials through a display arranged on the door body, and intelligent control such as temperature adjustment or mode adjustment of the refrigerator can be realized through an intelligent controller on the door body. But more functions means that more wires are needed to connect the door and the cabinet.

The door hinge is generally changed into a hollow structure for wiring. However, the door body designed at present is thinner and thinner, so that hollow structures available for wiring in the door body hinge are also reduced. Along with the intellectualization and multifunctionalization of the refrigerator, more and more circuits are connected with the refrigerator body. Thus, the existing hinge shaft structure cannot meet the wiring requirement of the refrigerator.

As shown in fig. 1 to 3, the embodiment of the present disclosure provides a case assembly including a case 1, a door 2, and a routing hinge group. Wherein, walk line hinge group includes: a first wire hinge shaft 3, a hinge plate 302, a second wire hinge shaft 301, and a connection rod 6.

The first wire hinge shaft 3 is arranged in the door body 2, the door body 2 can rotate around the first wire hinge shaft 3, and a first hollow structure for accommodating a first line is arranged inside the first wire hinge shaft 3. The hinge plate 302 is fixedly disposed on the case 1 at a first end, and is connected to the first routing hinge shaft 3 at a second end. The second wire hinge shaft 301 is disposed in the door body 2, and a second hollow structure for accommodating the second wire is disposed inside the second wire hinge shaft 301. The connection rod 6 includes a rotation end 601 rotated about the second routing hinge shaft 301 and an open free end 602 opposite to the rotation end 601, and a third hollow structure accommodating the second wire and communicating with the second hollow structure is provided inside the connection rod 6. The door body 2 rotates around the first wire hinge shaft 3 to open or close the opening of the box body 1, and the second wire hinge shaft 301 drives the connecting rod 6 to move during the rotation of the door body 2.

It can be appreciated that, since the first wire hinge shaft 3 and the second wire hinge shaft 301 are disposed in the door body 2, when the door body 2 rotates around the first wire hinge shaft 3, the second wire hinge shaft 301 moves circumferentially around the first wire hinge shaft 3 as a center of a circle. Thus, the second wire hinge shaft 301 moves away from the case 1 when the door 2 is opened, and the second wire hinge shaft 301 moves toward the case 1 when the door 2 is closed.

Specifically, after the second wire is installed, the second wire passing through the open free end 602 of the connection rod 6 leaves a length allowance or an elastic allowance so that the second wire does not interfere with the movement of the door body 2 due to the limited wire length or limited elasticity when the door body 2 rotates about the first wire hinge shaft 3. When the door 2 is in the closed condition, the connecting rod 6 is in the first position and the second line at the open free end 602 of the connecting rod 6 is in a bent condition. In the process of opening the door body 2, the second wire hinge shaft 301 drives the connecting rod 6 to slide towards the outer side of the box body 1, so as to drive the allowance of the second wire of the open free end 602 to be in an extended state. When the door body 2 is in the fully opened state, the second wire hinge shaft 301 drives the connecting rod 6 to move to the second position, and the second wire at the open free end 602 of the connecting rod 6 is in a straightened state. Similarly, during the closing process of the door 2, the second wire hinge shaft 301 drives the connecting rod 6 to slide into the box 1, so as to drive the remaining amount of the second wire of the open free end 602 to be in a bending state.

The box assembly provided by the embodiment of the disclosure performs line routing between the door body 2 and the box body 1 through the cooperation of the first line-routing hinge shaft 3 and the second line-routing hinge shaft 301, so that the line routing requirements of more lines can be met while the integral aesthetic degree of equipment is ensured.

In some embodiments, the door body 2 includes a pivoting sidewall 101. Wherein the distance from the first wire hinge shaft 3 to the pivoting sidewall 101 is smaller than the distance from the second wire hinge shaft 301 to the pivoting sidewall 101.

The first trace hinge shaft 3 is closer to the pivoting side wall of the door body 2 with respect to the second trace hinge shaft 301. When the door body 2 rotates about the first wire hinge shaft 3, the second wire hinge shaft 301 moves circularly about the first wire hinge shaft 3 as a center.

In some embodiments, the distance between the first trace hinge axis 3 and the second trace hinge axis 301 is less than or equal to the first preset distance.

It will be appreciated that the greater the distance between the first and second trace hinge axes 3, 301, the greater the length or spring margin of the second trace at the open free end 602 of the connecting rod 6. Thus, the second wire at the open free end 602 is more susceptible to twisting and the like.

Specifically, the distance between the first wire hinge shaft 3 and the second wire hinge shaft 301 is less than or equal to 50mm. For example, the distance between the first trace hinge axis 3 and the second trace hinge axis 301 is 10mm, 20mm, 30mm, 40mm, or 50mm.

The distance between the first wire hinge shaft 3 and the second wire hinge shaft 301 is smaller than or equal to the first preset distance, so that the length allowance or the elastic allowance of the second wire at the open free end 602 of the connecting rod 6 is reduced, and the second wire at the open free end 602 is further reduced from being wound.

As shown in fig. 4, in some embodiments, the connecting rod 6 includes a first routing rod 603 and a second routing rod 604. The first wire rod 603 is directly connected to the rotating end 601. The second trace bar 604 is connected to the first trace bar 603 in a bending manner.

Specifically, when the door 2 is in the closed state, the connection between the first wire rod 603 and the second wire rod 604 is located in the case 1. When the door 2 is in the open state, the connection between the first wire bar 603 and the second wire bar 604 is located outside the case 1.

In some embodiments, the bending angle between the first wire bar 603 and the second wire bar 604 of the connecting bar 6 is greater than 90 °.

Specifically, the bending angle between the first wire bar 603 and the second wire bar 604 is 100 °, 120 °, 140 °, or 160 °.

The bending angle between the first routing rod 603 and the second routing rod 604 of the connecting rod 6 is larger than 90 degrees, so that when the door body 2 moves, the connecting rod 6 moves along a preset track in the box body 1, and further, the connecting rod 6 is ensured not to interfere with the movement of the door body 2.

In some embodiments, the connecting rod 6 includes a second connecting portion 605 and a splice 606, and the second connecting portion 605 is detachably disposed with the splice 606.

It will be appreciated that the end of the second line connected to the housing 1 is provided with a terminal, and that the terminal is bulky. If the connection rod 6 is provided as an integrally formed structure, the terminal of the second line may not pass through the connection rod 6. Meanwhile, since the connecting rod 6 is long, the second connecting portion 605 and the splicing portion 606 of the connecting rod 6 are arranged to be of a detachable structure, and the wiring arrangement of the second circuit in the connecting rod 6 is convenient when the installation is performed.

Specifically, when the second wire passes through the second wire hinge shaft 301, the second wire needs to be connected to the case 1 through the connection rod 6. After the splicing part 606 and the second connecting part 605 of the connecting rod 6 are disassembled, the second circuit is put into the connecting rod 6 from the side surface of the second connecting part 605, and the terminal of the second circuit is positioned outside the open free end 602 of the connecting rod 6. After the second wires are placed in the second connecting portion 605 and arranged in order, the splicing portion 606 and the second connecting portion 605 are mounted together to prevent the second wires from being wound or interfering with the movement of the door body 2.

In some embodiments, the splice 606 is detachably disposed to the second connection 605 by a snap and fastener.

As shown in fig. 3, in some embodiments, the case assembly further includes a hinge box 7. The hinge box 7 is disposed above the case 1, and the open free end 602 of the connecting rod 6 is inserted into the hinge box 7.

Specifically, when the door body 2 is in the closed state, the second line of the open free end 602 of the connecting rod 6 is in a bent state within the hinge box 7. During the process of opening the door body 2, the second wire hinge shaft 301 drives the open free end 602 of the connecting rod 6 to move in the hinge box 7. When the door body 2 is opened to a maximum angle, the open free end 602 of the connecting rod 6 is still located in the hinge box 7, and the second line is in a straightened or stretched state in the hinge box 7.

In some embodiments, the hinge box 7 includes a first bump stop 701 and a second bump stop 702. The first limit stop 701 is used for abutting against the second connecting portion 605 of the connecting rod 6, the second limit stop 702 is used for abutting against the splicing portion 606 of the connecting rod 6, and the second limit stop 702 is opposite to the first limit stop 701. When the door body 2 is opened to the first angle, the second connecting portion 605 of the connecting rod 6 abuts against the first limit stop 701, so that the connecting rod 6 slides toward the second limit stop 702 under the abutting action of the first limit stop 701. When the door body 2 is opened to the second angle, the splice 606 abuts against the second limit stop 702, so that the connecting rod 6 slides toward the first limit stop 701 under the abutting action of the second limit stop 702.

In some embodiments, the first angle is less than the second angle.

Further, when the connecting rod 6 slides to the first limit stop 701 again and is stopped by the first limit stop 701, the second connecting portion 605 of the connecting rod 6 slides against the first limit stop 701 until the door body 2 is opened to a maximum angle.

Specifically, when the door body 2 is in the closed state, the connecting lever 6 is located at the first position. The door body 2 rotates around the first wire hinge shaft 3 to drive the second wire hinge shaft 301 to do circular motion, and then drive the connecting rod 6 to move. When the door body 2 is opened to the first angle, the first limit stop 701 abuts against the second connection portion 605 of the connection rod 6, so that the connection rod 6 slides toward the second limit stop 702. When the door body 2 is opened to the second angle, the second limit stop 702 abuts against the splicing portion 606 of the connecting rod 6, so that the connecting rod 6 slides toward the first limit stop 701. After the connecting rod 6 slides to the first limit stop 701 again, the connecting rod is stopped by the first limit stop 701, and the second connecting portion 605 of the connecting rod 6 slides in a fitting manner with the first limit stop 701. Meanwhile, the open free end 602 of the connection rod 6 slides in contact with the inner wall surface of the hinge box 7, and the connection rod 6 rotates about the second cabling hinge shaft 301 during the sliding.

It will be appreciated that, due to the stopping action of the first and second bump stops 701, 702 on the connecting rod 6, the first wire does not interfere with the movement of the second wire when the door body 2 rotates, preventing the second wire and the first wire from being wound.

As shown in fig. 5, in some embodiments, the distance between the first bump stop 701 and the second bump stop 702 is greater than the width of the connecting rod 6.

Specifically, when the first bump stopper 701 abuts against the connecting rod 6, a gap exists between the second bump stopper 702 and the connecting rod 6. Similarly, when the second bump stopper 702 abuts against the connection rod 6, a gap exists between the first bump stopper 701 and the connection rod 6, so that the connection rod 6 can smoothly protrude from between the first bump stopper 701 and the second bump stopper 702 along with the movement of the second cabling hinge shaft 301 during the opening of the door body 2, and move in a predetermined track.

In some embodiments, the distance between the first bump stop 701 and the second bump stop 702 is less than or equal to a second predetermined distance.

Specifically, the distance between the first bump stop 701 and the second bump stop 702 is less than or equal to 80mm and greater than or equal to 5mm. For example, the distance between the first bump stop 701 and the second bump stop 702 may be 5mm, 10mm, 30mm, 50mm, 70mm, or 80mm.

It will be appreciated that the distance between the first limit stop 701 and the second limit stop 702 may be set according to the width of the connecting rod 6, and that the larger the width of the connecting rod 6, the larger the distance between the first limit stop 701 and the second limit stop 702, and the smaller the width of the connecting rod 6, the smaller the distance between the first limit stop 701 and the second limit stop 702. For example, when the width of the connecting rod 6 is set to 30mm, the distance between the first limit stop 701 and the second limit stop 702 is set to 40mm.

In some embodiments, the hinge box 7 further comprises a hinge box cover. The hinge box cover is detachably arranged at the opening of the top surface of the hinge box 7, and can completely cover the opening of the top surface of the hinge box 7.

In particular, the hinge box cover may cover an opening in the top surface of the hinge box 7 to prevent the second line from leaking out or dust from falling into the hinge box 7.

In some embodiments, the hinge box cover may cover the first trace hinge shaft 3 to prevent the first trace from leaking out.

In some embodiments, the open free end 602 of the connecting rod 6 is provided with a bent structure.

In some embodiments, the hinge plate 302 is connected at a first end to a second end.

In some embodiments, the hinge plate 302 is provided with a stiffener at the junction of the first and second ends to strengthen the load bearing capacity of the hinge plate 302.

Optionally, the door body 2 is a main door of the refrigeration device, and the routing hinge group is a hinge mounted on the main door.

As shown in fig. 6, in some embodiments, the door body includes a main door, a sub door 4, a sub door trace hinge shaft 5, and a sub door hinge base 501. The first and second wire hinge shafts 3 and 301 are provided in the main door. The auxiliary door wiring hinge shaft 5 is arranged in the auxiliary door 4. A fourth hollow structure for accommodating wires is provided inside the sub-door trace hinge shaft 5. The first end of the auxiliary door hinge seat 501 is fixedly arranged on the main door, and the second end is connected with the auxiliary door wiring hinge shaft 5. Wherein the sub door 4 rotates about the sub door trace hinge shaft 5 to open or close the opening of the main door. It will be appreciated that the main door may be numbered 2 in fig. 6, and that the set of routing hinges of the main door in fig. 6 is not shown.

As shown in fig. 7, in some embodiments, at least one surface of the sub-door trace hinge shaft 5 is provided with one or more first communication connection ports 502. Each of the first communication connection ports 502 is for electrically connecting with an electrical connection port in the sub-door 4.

In some embodiments, the cabling hinge set further includes a secondary door hinge mount 501. The sub door hinge seat 501 is provided with a groove 511, the groove 511 is used for accommodating the sub door trace hinge shaft 5, and at least one inner wall of the groove 511 is provided with one or more second communication connection ports 512. The second communication connection ports 512 are used for electrically connecting with terminals located outside the auxiliary door hinge seat 501, and the second communication connection ports 512 are in one-to-one correspondence with the first communication connection ports 502.

When the auxiliary door wire hinge shaft 5 is inserted into the groove 511, and the auxiliary door wire hinge shaft 5 and the auxiliary door hinge base 501 are relatively stationary and relatively rotating, each first communication connection port 502 is connected with a corresponding second communication connection port 512 to realize communication.

The embodiment of the present disclosure provides a case assembly, and the first communication connection port 502 is electrically connected with an electrical connection port in the sub-door 4. The second communication connection port 512 in the sub-door hinge seat 501 is electrically connected to a terminal located outside the sub-door hinge seat 501. By inserting the auxiliary door wiring hinge shaft 5 into the groove 511 in the auxiliary door hinge base 501, connection communication between the first communication connection port 502 and the second communication connection port 512 can be achieved, so that electrical connection between the electrical connection port and the terminal during opening and closing of the auxiliary door 4 can be achieved. The terminal does not need to pass through the hinge of the auxiliary door 4, so that the box body assembly provided by the embodiment of the disclosure can easily realize connection of the terminal and the interface in the box body 1.

For the auxiliary door wiring hinge shaft 5, one end is fixedly connected with the auxiliary door 4, and the other end is rotatably connected with the auxiliary door hinge seat 501. The sub door 4 may be rotatably fixed to the sub door hinge base 501 by the sub door trace hinge shaft 5.

As shown in fig. 8, in some embodiments, the shape of the sub-door trace hinge shaft 5 includes one or more of a cylinder, a cone, a truncated cone, a stepped cylinder, a stepped cone, and a stepped truncated cone.

By setting the shape of the auxiliary door trace hinge shaft 5 to one or more of a cylinder, a cone, a round table, a stepped cylinder, a stepped cone and a stepped round table, the rotatable connection of the auxiliary door trace hinge shaft 5 and the auxiliary door hinge base 501 is facilitated.
