Figure 1-14, clearly and completely describe the technical solutions in the implementation mode of the utility model.

[0044] The embodiment of the utility model provides a refrigerator, such as Figure 1 and Figure 2 As shown, the refrigerator includes a cabinet 10, a door 20, and a hinge mechanism 30. The hinge mechanism 30 is connected between the cabinet 10 and the door 20, and the door 20 can be opened or closed.

[0045] In a specific embodiment, the above-mentioned refrigerator is a built-in upright refrigerator, but of course, it is not limited to this.

[0046] Reference Figure 3 and Figure 4 The refrigerator also includes a wiring mechanism 40, and the hinge mechanism 30 is arranged below the wiring mechanism 40, so that the hinge mechanism 30 is closer to the top surface of the door body 20, the connection strength between the hinge mechanism 30 and the door body 20 is increased, and the switching of the door body 20 between the open and closed positions is smoother.

[0047] Reference Figure 5 and Figure 6 The wiring mechanism 40 includes a hinge box 41, a first guide rod 42, a second guide rod 43, and a wiring box 45. The hinge box 41, the first guide rod 42, the second guide rod 43, and the wiring box 45 are respectively provided with channels for transmitting the lines, so that the lines are connected from the box body 10 to the door body 20.

[0048] Specifically, the lines include but are not limited to cables, water pipes, condensation pipes, etc.

[0049] The wiring mechanism 40 forms a foldable structure by pivoting, and when the door body 20 is opened and closed, the wiring mechanism 40 opens and folds accordingly. Specifically, the hinge box 41 includes a main body 411 and a protruding portion 412 extending from the main body 411 to one side of the door body 20, and the main body 411 is fixedly connected to the box body 10. One end of the first guide rod 42 is rotatably connected to the protruding portion 412, and the other end of the first guide rod 42 is rotatably connected to one end of the second guide rod 43, and the other end of the second guide rod 43 is rotatably connected to the wiring box 45, and the wiring box 45 is connected to the door body 20. In this way, the overall structure of the wiring mechanism 40 is simple and easier to install.

[0050] A recess is formed between the main body 411 and the protruding portion 412 . When the wiring mechanism 40 is in the folded position, the recess provides a folding space for the first guide rod 42 , making the overall structure of the wiring mechanism 40 more compact.

[0051] The first guide rod 42 and the hinge box 41 are rotatably connected at the first hinge point 40a, and the second guide rod 43 and the wiring box 45 are rotatably connected at the second hinge point 40b.

[0052] Preferably, refer to Figure 7 The second guide rod 43 has a bend O, and the opening of the bend O faces the first hinge point 40a. The angle α formed by the bend O is 85° to 105°. The second guide rod 43 is generally an L-shaped rod. The bend O divides the second guide rod 43 into a first section P and a second section Q. The first section P is generally parallel to the first guide rod 42.

[0053] In other embodiments, reference Figure 8 The first guide rod 42 has a bend O, the opening of which faces the second hinge point 40 b. The bend O divides the first guide rod 42 into a first section P and a second section Q. The first section P is substantially parallel to the second guide rod 43 .

[0054] In other embodiments, reference Fig. 9 The first guide rod 42 has a bend O1, and the opening of the bend O1 faces the second hinge point 40b. The second guide rod 43 has a bend O2, and the opening of the bend O2 faces the first hinge point 40a. The first guide rod 42 and the second guide rod 43 are both substantially L-shaped rods, so that a part of the structure of the first guide rod 42 is substantially parallel to a part of the structure of the second guide rod 43.

[0055] In other embodiments, the first guide rod 42 or the second guide rod 43 has a bend O1 and a bend O2, the opening of the bend O1 faces the second hinge point 40b, and the opening of the bend O2 faces the first hinge point 40a. One end of the first guide rod 42 or the second guide rod 43 is a hook-shaped structure (not shown), so that a part of the structure of the first guide rod 42 is roughly parallel to a part of the structure of the second guide rod 43.

[0056] This embodiment provides a refrigerator, referring to Fig.10 and Fig.11 The protruding portion 412 is provided with a first clearance groove 413 for the end of the first guide rod 42 to pass through and extend, so that one end of the first guide rod 42 extends into the protruding portion 412 and is rotatably connected to the protruding portion 412. The other end of the first guide rod 42 is provided with a second clearance groove 421 for the end of the second guide rod 43 to pass through and extend, and the thickness of the first guide rod 42 is greater than the thickness of the second guide rod 43, so that one end of the second guide rod 43 extends into the first guide rod 42 and is rotatably connected to the first guide rod 42.

[0057] The hinge box 41, the first guide rod 42, and the second guide rod 43 are all hollow inside, and the side wall of the hinge box 41 and the wall at the end of the first guide rod 42 and the second guide rod 43 are respectively provided with wire-passing grooves for passing the wires, so as to facilitate the passing of the wires.

[0058] Preferably, refer to Fig.11At least two winding posts 414 are provided in the hinge box 41, and the line is wound on the winding posts 414. The winding posts 414 can adjust the angle of the line so that the line is arranged in an S shape in the hinge box 41. When the line passing mechanism is opened and folded, the friction between the line and the side wall of the line passing groove is reduced, thereby avoiding line wear and breakage.

[0059] Reference Fig.10 - Fig.12 The first guide rod 42 includes a first box body 422 and a first cover body 423 fixedly engaged with the first box body 422, and the second guide rod 43 includes a second box body 431 and a second cover body 432 engaged with the second box body 431. Both the first box body 422 and the second box body 431 are semi-enclosed structures with open top surfaces, and the inner walls of the first box body 422 and the second box body 431 are surrounded by stepped surfaces, and the first cover body 423 and the second cover body 432 are engaged with the stepped surfaces of the first box body 422 and the second box body 431, respectively.

[0060] Specifically, a snap-fit ​​structure 424 is provided at the joint position of the first box body 422 and the first cover body 423 , including but not limited to a snap block and a snap slot structure.

[0061] The first box body 422 has two opposite inner walls formed with ribs 427, which extend toward the center of the first box body 422. The ribs 427 can limit the circuits, so that the circuits converge toward the center of the first box body 422, thereby preventing the circuits from getting stuck when the wiring mechanism 40 is opened or folded. In addition, the ribs 427 increase the structural strength of the first box body 422.

[0062] The two ends of the first guide rod 42 are connected to the hinge box 41 and the second guide rod 43 by fasteners. At the connection position with the hinge box 41, the first box body 422 and the first cover body 423 are respectively provided with first connection holes 425 for the fasteners to pass through. At the connection position with the second guide rod 43, the first cover body 423 is provided with a second connection hole 426 for the fasteners to pass through. As a result, the width of the two ends of the first guide rod 42 is greater than the width of the middle position of the two ends, so that the two ends of the first guide rod 42 have enough space for passing the line, and can also provide enough rotation space for the second guide rod 43. The outer edges of the two ends of the first guide rod 42 are in the shape of arcs, which reduces the rotation space required for the first guide rod 42 when it is rotated to open and folded.

[0063] The end of the second box body 431 close to the first guide rod 42 is connected to a connecting column 433, and correspondingly, the second cover body 432 is provided with an avoidance hole. During the installation process, the fastener passes through the first cover body 423 and the second cover body 432 in sequence, and is connected and fixed with the connecting column 433. Therefore, the width of the end of the second guide rod 43 close to the first guide rod 42 is greater than the width of other positions and the outer edge shape is an arc shape, which can not only provide sufficient space for threading, but also reduce the rotation space required for the second guide rod 43 when rotating to open and fold.

[0064] Reference Fig.12 , the second box body 431 and the second cover body 432 are spliced ​​at one end away from the first guide rod 42 to form a pivoting clamping shaft structure. Specifically, the second box body 431 is connected with a clamping ring 434, the bottom of the clamping ring 434 is a full ring a, and the top is a half ring b. The second cover body 432 is connected with a clamping block 435, the clamping block 435 is engaged with the top of the clamping ring 434, and the clamping block 435 is two semi-ring structures (c, d), the thickness of the semi-ring c is greater than the thickness of the semi-ring d, and the outer edge formed by the splicing of the semi-ring c and the semi-ring b is a full circle, and the diameter of the full circle is the same as the diameter of the full ring a. The semi-ring d is engaged with the inner wall of the semi-ring b. The clamping ring 434 and the clamping block 435 enclose a wire hole 436 for the line to pass through.

[0065] Reference Fig.13 The wiring box 45 includes a first splicing block 451 and a second splicing block 452 that are fixed to each other. The first splicing block 451 and the second splicing block 452 are substantially arranged in a long strip shape and are arranged up and down.

[0066] In a specific embodiment, the first splicing block 451 is fixedly connected with the door body 20, and a fixing column 453 is provided at one end of the second splicing block 452. The fixing column 453 is provided with a fixing hole for fasteners to pass through, and a positioning groove 455 is provided at the bottom of the fixing column 453. A connecting plate 21 can be installed on the door body 20, and the wiring box 45 is installed on the connecting plate 21. The connecting plate 21 is provided with a limiting column 22 that is engaged with the positioning groove 455, and the limiting column 22 is also provided with a fixing hole for fasteners to pass through. Of course, the connection method of the first splicing block 451 and the second splicing block 452 to the door body 20 is not limited to this.

[0067] The first assembly block 451 and the second assembly block 452 are provided with a receiving cavity 456 for receiving the second guide rod 43 on one side thereof. In the closed state, the second guide rod 43 is folded in the receiving cavity 456. The first assembly block 451 and the second assembly block 452 are provided with a pivoting groove 457 on the wall of the receiving groove thereof to engage with the pivoting shaft structure.

[0068] Reference Fig.14A wiring groove 458 connected to the pivot groove 457 is provided in the second splicing block 452, and a wiring gap is reserved between the pivot axis and the bottom surface of the pivot groove 457 for the line to pass through. The line enters the wiring groove 458 through the wiring gap and is then connected to the electronic components on the door body 20.

[0069] Preferably, the positions of the fixing column 453 and the limiting column 22 are closer to the edge of the door body 20 to avoid interference with the position of the wiring groove 458, so as to facilitate the laying and transmission of the line, and can also give way to the connection point between the second guide rod 43 with a turning point and the wiring box 45.

[0070] In other embodiments, the positions of the fixing column 453 and the limiting column 22 are closer to the center of the door body 20 to facilitate the connection between the second guide rod 43 without an inflection point and the wiring box 45 .

[0071] Through the specific structural setting of the above-mentioned wiring mechanism 40, when the door body 20 is opened or closed relative to the box body 10, the wiring mechanism 40 also opens or folds with the door body 20, which not only guides the line smoothly but also plays a role in safety protection of the line.

[0072] The wiring mechanism 40 has a simple overall structure and occupies a small installation space. During the installation process, the hinge box 41 is installed on the box body 10, so that the line passes through the winding column 414 and then passes through the hinge box 41. After the first guide rod 42 and the second guide rod 43 are assembled, the first guide rod 42 and the second guide rod 43 are pivotally connected by fasteners. The line passes through the wire groove on the first guide rod 42, the channel in the first guide rod 42, the wire groove on the second guide rod 43, the channel in the second guide rod 43, and the wire hole 436 in sequence. The second splicing block 452 is fixedly connected to the door body 20, so that the second guide rod 43 is engaged with the second splicing block 452, and the line passes through the wiring groove 458, and then the first splicing block 451 is installed on the second splicing block 452, and the first splicing block 451 is fixed by fasteners.

[0073] As a preferred solution of this embodiment, the hinge box 41, the first box body 422, the first cover body 423, the second box body 431, and the second cover body 432 are all made of bent or cast metal plates, but of course, this is not limited to this.

[0074] In other embodiments, the first guide rod 42, the second guide rod 43, and the wiring box 45 may not be a split structure. Without affecting the wire passing, the first guide rod 42, the second guide rod 43, and the wiring box 45 may be an integrated structure with a wire passing channel inside.

[0075] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings.
