TECHNICAL FIELD
[0001] The present application relates to the technical field of refrigeration equipment power transmission, in particular to a freezing assembly and a refrigerator. BACKGROUND
[0002] With the development of the intelligence and multifunction of the refrigerator, some functional modules are usually arranged on the freezing door of the refrigerator, such as automatic door opening buttons, touch modules, etc. These functional modules usually need to be connected with the control module in the cabinet through wiring to realize the power supply of the functional modules on the freezing door of the refrigerator.
[0003] The existing refrigerator freezing door mainly uses a pull-open structure, and the wires are usually arranged along the edge of the door body or the guide rail when fixed. In the process of opening and closing the refrigerator freezing door, the wires will move with the reciprocating movement of the refrigerator freezing door. In this process, the wires may be hung and pulled by the articles, and the wires may be damaged when being pulled too much. CONTENT OF THE UTILITY MODEL

[0010] a wire assembly wound on the connecting rod assembly in a spiral manner, and the wire assembly being capable of axial extension and radial deformation following the extension of the connecting rod assembly, the wire assembly comprising a wire and a spring steel, the wire being fixed on the spring steel and electrically connected with the electrical element.
[0011] It can be understood that by arranging the spring steel and winding the wire on the connecting rod assembly after being fixed on the spring steel, the wire and the spring steel can synchronously perform axial extension and radial deformation following the extension of the connecting rod. Since the wire is fixedly wound on the connecting rod assembly with the spring steel, and the wire deforms following the spring steel, the spring steel has a limiting effect on the wire, so that the problem of damage of the wire caused by excessive pulling can be avoided. In addition, winding the wire and the spring steel on the connecting rod assembly can avoid the contact and friction between the wire and other structures on the freezing door body, so that the problem of wear of the wire after long-term use can be avoided.
[0012] In one of the embodiments, one end of the spring steel is fixedly connected with the freezing liner, and the other end of the spring steel is fixedly connected with the freezing door body.
[0013] In one of the embodiments, the wire assembly further comprises a flexible sleeve, which is sleeved on the wire and the spring steel to fixedly connect the wire and the spring steel.
[0014] In the embodiment, the wire and the spring steel are arranged through the flexible sleeve.
[0015] It can be understood that, by arranging the flexible sleeve and mechanically connecting the wire and the spring steel by the flexible sleeve, the wire can be prevented from loosening or shifting during the spiral winding. In addition, the arrangement of the flexible sleeve can also protect the wire and avoid the problem of hardening of the wire at low temperature.
[0016] In one of the embodiments, the flexible sleeve is configured as a silica gel sleeve.
[0017] In one of the embodiments, the wire and the spring steel are arranged in insulation.
[0018] It can be understood that, by arranging the wire and the spring steel in insulation, the problem of electrical short circuit caused by the contact between the spring steel and the wire can be prevented.
[0019] In one of the embodiments, the number of the link assemblies is configured as two groups, and the two groups of the link assemblies are arranged on both sides of the freezing door body in the width direction of the refrigerator to support the freezing door body.
[0020] It can be understood that, by arranging the two groups of the link assemblies on both sides of the freezing door body in the width direction of the refrigerator, the weight load of the door body can be dispersed, and the support stability can be improved.
[0021] In one of the embodiments, the number of the wire assemblies is configured as one group, and the wire assembly is spirally wound on one group of the link assemblies.
[0022] In one of the embodiments, the link assembly comprises a first link and a second link, and the second link is sleeved on the first link and is in sliding connection with the first link.
[0023] In the embodiment, one end of the first link away from the second link is connected with the freezing liner, and one end of the second link away from the first link is connected with the freezing door body.
[0024] In one of the embodiments, the freezing assembly further comprises a top door mechanism, which is installed on the freezing liner to push the freezing door body and open the freezing door body.
[0025] The electrical element is configured as a trigger for controlling the opening of the top door mechanism.
[0026] The application also provides the following technical solutions:
[0027] A refrigerator comprises the freezing assembly according to any one of the above embodiments.
[0028] Compared with the prior art, the freezing assembly is provided with spring steel, and the wire is fixed to the spring steel and then wound on the connecting rod assembly, so that the wire and the spring steel can synchronously perform axial extension and contraction and radial deformation along with the extension and contraction of the connecting rod. Since the wire is fixedly wound on the connecting rod assembly together with the spring steel, and the wire deforms along with the spring steel, the spring steel has a limiting effect on the wire, so that the problem of damage of the wire caused by excessive pulling can be avoided. In addition, the wire and the spring steel are wound on the connecting rod assembly, so that the wire can be prevented from contacting and rubbing against other structures on the freezing door body, thereby avoiding the problem of wear of the wire caused by long-term use.

[0040] Reference will now be made to Figures 1 to 3The application provides a freezing assembly 100, which comprises a freezing inner container 10, a freezing door body 20, a connecting rod assembly 30 and a wire assembly 40. The freezing door body 20 is provided with an electrical element. The connecting rod assembly 30 is configured in a telescopic structure and is in driving connection with the freezing inner container 10 and the freezing door body 20 respectively. The wire assembly 40 is wound on the connecting rod assembly 30 in a spiral manner and can axially extend and contract and radially deform along with the extension and contraction of the connecting rod assembly 30. The wire assembly 40 comprises a wire 41 and a spring steel 42. The wire 41 is fixed on the spring steel 42 and is in electrical connection with the electrical element. In this way, the wire 41 and the spring steel 42 can axially extend and contract and radially deform along with the extension and contraction of the connecting rod by fixing the wire 41 on the spring steel 42 and winding the wire 41 on the connecting rod assembly 30. On the one hand, the wire 41 and the spring steel 42 are fixed and deformed along with the spring steel 42, so that the spring steel 42 has a limiting effect on the wire 41, thereby avoiding the problem of excessive pulling and bending of the wire 41. On the other hand, the wire 41 and the spring steel 42 are wound on the connecting rod assembly 30, which can avoid the contact and friction between the wire 41 and other structures on the freezing door body 20, thereby avoiding the problem of wear of the wire 41 after long-term use.
[0041] Here, the electrical element can be any structure that needs to be electrically connected, such as a trigger button, a signal generator, a signal receiver, an electrical connector, etc. Through the electrical connection between the electrical element and the wire assembly 40, the control module in the box can supply power to the electrical element or transmit signals to the electrical element.
[0042] In an embodiment, the number of connecting rod assemblies 30 is configured as two groups. The two groups of connecting rod assemblies 30 are arranged on both sides of the freezing door body 20 in the width direction of the refrigerator and are used for supporting the freezing door body 20. By arranging the two groups of connecting rod assemblies 30 on both sides of the freezing door body 20 in the width direction of the refrigerator, the door body weight load can be dispersed, and the support stability can be improved. Of course, it is not limited to this. In other embodiments, the number of connecting rod assemblies 30 can also be configured as multiple groups, such as four groups, six groups, etc. Different numbers of connecting rod assemblies 30 can be selected according to the structure and size of the refrigerator.
[0043] Further, the connecting rod assembly 30 comprises a first connecting rod 31 and a second connecting rod 32.

Here, the connecting plate 33 is fixed to the freezing door body 20 and the freezing liner 10 by screws.
[0045] Please refer to Figure 1 and Figure 3 , one end of the spring steel 42 is fixed to the freezing liner 10, and the other end of the spring steel 42 is fixed to the freezing door body 20. Here, the spring steel 42 and the freezing liner 10 can be fixed by welding, screw connection, clamping and the like, which are common in the prior art and will not be described here.
[0046] Specifically, the spring steel 42 can be configured of carbon spring steel, alloy spring steel and the like.
[0047] In an embodiment, the wire 41 is insulated from the spring steel 42. In this way, by insulating the wire 41 from the spring steel 42, the problem of electrical short circuit caused by contact between the spring steel 42 and the wire 41 can be prevented. Here, the wire 41 is provided with an insulating layer 411, for example, a silicone rubber can be provided on the outer layer of the wire 41 by integral injection molding to insulate the wire 41 from the spring steel 42.

It can be understood that by providing the flexible sleeve 43, the wire 41 and the spring steel 42 are mechanically connected and fixed by the flexible sleeve 43, which can prevent the wire 41 from loosening or shifting during the spiral winding. In addition, the provision of the flexible sleeve 43 can also protect the wire 41 from hardening at low temperature.
[0049] Here, the material of the flexible sleeve 43 can be configured of silicone, thermoplastic elastomer, polyethylene and the like.
[0050] In the embodiment, the flexible sleeve 43 is configured of a silicone sleeve. Silicone can withstand low temperature and has high elasticity, flexibility and bending resistance. It will not crack due to low temperature catalysis during long-term use, and will not crack after repeated stretching and contraction, which can effectively protect the wire 41.

Here, the group of wire assemblies 40 includes two wires 41 (VCC and GND respectively) and a spring steel 42, and a silica gel sleeve is sleeved outside the wires 41 and the spring steel 42. In other embodiments, the wire assemblies 40 can also include multiple wires 41, which can be connected to different electrical elements respectively. Or the number of wire assemblies 40 is configured as multiple groups, which are arranged on different groups of link assemblies 30 to meet different power supply or signal transmission requirements on the freezer door body 20.
[0052] In the embodiment, the number of wire assemblies 40 is configured as two groups, which are wound on two different groups of link assemblies 30 in a spiral manner.
