Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a appliance that keeps food or other items at a constant low temperature. With the development of science and technology and the improvement of people's living standards, refrigerators have become an indispensable appliance in life and production.

[0003] Typically, refrigerators have multiple shelves inside. These shelves are a crucial component, dividing the interior space into smaller compartments for storing food and maximizing storage capacity. High-end refrigerators, for aesthetic reasons, often feature cantilevered shelves. These shelves are supported by cantilever arms extending from the refrigerator's sides, facilitating installation and removal. Because of the need for detachable installation, cantilevered shelves face power limitations; they cannot be self-illuminating and require an external power supply.

[0004] In related technologies, the shelves can be height-adjusted by supporting cantilever to divide the internal space of the refrigerator as needed. In order to achieve the effect of the shelves illuminating at different heights, multiple power supply components need to be set up for different heights, resulting in high costs and complex internal structures. Utility Model Content

[0005] The purpose of this application is to provide a refrigerator that can achieve a set of conductive components to meet the power supply requirements of different shelf heights, thereby reducing costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a refrigerator, comprising a cabinet, an inner liner, shelves, two supporting cantilever arms, a decorative component, a lamp body, a lifting bracket, and conductive components; the inner liner is disposed within the cabinet, and the inner liner is constructed to form a refrigeration compartment with a front opening; the shelves are plate-shaped structures and are horizontally disposed within the refrigeration compartment; the two supporting cantilever arms are respectively disposed on the left and right sides of the bottom of the shelves, for supporting the left and right ends of the shelves respectively, and the height of the supporting cantilever arms is adjustable; the decorative component is fixed to the shelves; the lamp body is disposed on the decorative component, and the lamp body... An electrical connection terminal is provided; a lifting bracket is disposed in the refrigeration room, and the lifting bracket has multiple slots spaced apart along the height direction, the positions of the multiple slots corresponding to different adjustable heights of the support cantilever; one end of a conductive component is used to connect to a power source, and the other end abuts against the electrical connection terminal to conduct the power source to the lamp body; wherein, the conductive component is movably disposed on the lifting bracket, and the conductive component can move along the height direction of the lifting bracket with the shelf and the support cantilever, and engage in the slots corresponding to the height of the support cantilever.

[0008] The above-mentioned technical features have at least the following technical effects:

[0009] By incorporating conductive components, an external power source is connected to the lamp body, causing the lamp body to emit light, which in turn illuminates the shelf. Simultaneously, a lifting bracket is installed with multiple slots spaced vertically along its length. The positions of these slots correspond to different adjustable heights of the support cantilever. When adjusting the shelf height via the support cantilever, the conductive components are engaged in the slots corresponding to the cantilever height, thus fixing the height of the conductive components. This allows a single conductive component to meet the power supply needs of the shelf at different heights, resulting in low cost and a simpler structure.

[0010] In some embodiments of this application, the lifting bracket is further provided with a lifting channel extending in the height direction on the same side of the plurality of slots, and each of the slots and the lifting channel are connected.

[0011] When the height of the support cantilever is adjusted, the conductive component can move into the lifting channel and engage with the slot corresponding to the height of the support cantilever.

[0012] The above-mentioned technical features have at least the following technical effects:

[0013] By opening a lifting channel on the same side of multiple card slots, and connecting the lifting channel with the card slots, the conductive component can move between the current card slot and the target card slot through the lifting channel, so that the conductive component can switch to the card slot of the corresponding height as the height of the shelf changes.

[0014] In some embodiments of this application, the conductive component includes:

[0015] The housing forms a hollow mounting cavity, and the end of the housing facing the electrical connection terminal has a mounting hole that communicates with the mounting cavity;

[0016] The fixing rod has one end fixedly connected to the box body and the other end snapped into the slot;

[0017] A conductive contact is disposed in the mounting cavity, one end of which is used for electrical connection with the power supply, and the other end extends out from the mounting hole and abuts against the electrical connection end.

[0018] The above-mentioned technical features have at least the following technical effects:

[0019] The conductive component is housed within a housing to form a mounting cavity, which protects the conductive contacts and prevents accidental leakage, thus enhancing safety. The housing is secured to the slot by a fixing rod, fixing the conductive component and the lifting bracket while facilitating its transfer to the corresponding slot via the lifting channel.

[0020] In some embodiments of this application, the conductive contact is retractably disposed in the mounting hole to abut against the electrical connection end.

[0021] The above-mentioned technical features have at least the following technical effects:

[0022] By making the conductive contact retractable, the tightness between the conductive contact and the electrical connection terminal can be adjusted by setting the degree of retraction of the conductive contact, thus avoiding poor contact between the conductive contact and the electrical connection terminal.

[0023] In some embodiments of this application, the conductive contact includes:

[0024] A contact base is snapped into the mounting hole, and the contact base has a guide channel along the axial direction of the mounting hole, with one end of the guide channel facing the electrical connection end.

[0025] The contact is slidably disposed in the guide channel, with one end extending out of the mounting hole;

[0026] An elastic element is disposed in the guide channel and connected to the contact to apply an elastic force to the contact so that the outer end of the contact abuts against the electrical connection terminal.

[0027] The above-mentioned technical features have at least the following technical effects:

[0028] The conductive contact is equipped with an elastic element that is connected to a sliding contact. The elastic element applies an elastic force to the contact, causing the outer end of the contact to abut against the electrical connection end. At the same time, the elastic force of the elastic element keeps the contact and the electrical connection end tightly pressed together, preventing poor contact.

[0029] In some embodiments of this application, the decorative element is disposed at the rear end of the shelf, the decorative element has an internal structure forming a receiving cavity opened along its length direction, the lamp body is disposed in the receiving cavity, and the rear end of the decorative element has an exposed hole opposite to the electrical connection end.

[0030] The housing is located on the rear side of the decorative element, and the mounting hole is opposite to the exposed hole so that the contact can abut against the electrical connection terminal.

[0031] The above-mentioned technical features have at least the following technical effects:

[0032] By placing the decorative element at the rear of the shelf, the light fixture can be prevented from being seen from the front, thus preserving the shelf's aesthetics. By positioning the housing behind the decorative element, the contacts naturally engage with the electrical connection point when the shelf is pushed back to the preset position, enabling contact power supply. Removing the shelf forward automatically disconnects the power, making the power supply method simple and efficient.

[0033] In some embodiments of this application, the decorative element includes a sealing ring, which is annular and sandwiched between the electrical connection end and the inner end of the exposed hole;

[0034] The side of the electrical connection terminal facing the exposed hole is provided with an anti-rust coating.

[0035] The above-mentioned technical features have at least the following technical effects:

[0036] By incorporating a sealing ring, the lamp body can be sealed, allowing only the electrical connection terminals to be exposed outside the decorative elements. This prevents moisture from entering the cavity and corroding the circuitry and light-emitting components on the lamp body. Applying an anti-rust coating to the electrical connection terminals enhances their rust resistance, preventing them from being corroded and failing due to external moisture.

[0037] In some embodiments of this application, a toggle part protrudes from the outer wall of the box, the toggle part is exposed in the refrigeration chamber, and the toggle part is used to toggle the box, so that it drives the fixing rod to move between the slot and the lifting channel.

[0038] The above-mentioned technical features have at least the following technical effects:

[0039] By incorporating a toggle mechanism, the user can easily grip and move the box, and adjust the conductive components by engaging them in different slots, thus improving operational convenience.

[0040] In some embodiments of this application, the refrigerator further includes an air duct cover plate disposed on the rear side of the refrigeration compartment, with a gap between the side portion of the air duct cover plate and the left and right side walls of the refrigeration compartment to form an adjustment space, the lifting bracket being located on the back side of the air duct cover plate, and the conductive contact and the toggle part being exposed in the adjustment space.

[0041] The above-mentioned technical features have at least the following technical effects:

[0042] By installing an air duct cover to create an adjustment space with the side wall of the refrigeration compartment, and placing the lifting bracket on the back side of the air duct cover, it is possible to avoid exposing it to the refrigeration compartment and affecting the interior aesthetics. At the same time, exposing the conductive contacts and toggle parts in the adjustment space allows users to easily reach into the adjustment space to control the movement of the box, thereby facilitating the adjustment of the height of the conductive components to accommodate the adjustment of the shelf height.

[0043] In some embodiments of this application, the refrigerator further includes two hanging racks, which are respectively disposed on the left and right inner walls of the inner liner. The hanging racks are provided with multiple support parts at intervals along the height direction. One end of each support part extends into the adjustment space, and the support cantilever is detachably connected to one end of the support part that extends into the adjustment space.

[0044] The above-mentioned technical features have at least the following technical effects:

[0045] By installing two hanging brackets, which are detachably connected to the support cantilever via a support section, the height of the support cantilever can be adjusted by connecting to support sections of different heights. This allows users to easily adjust the height of the shelves according to their actual needs. Simultaneously, extending the support section into the adjustment space allows it to be concealed within the space, enhancing the aesthetics of the refrigeration room.

[0046] Beneficial effects:

[0047] In this application, a conductive component is used to conduct external power to the lamp body, thereby illuminating the lamp body and thus illuminating the shelf. Simultaneously, a lifting bracket is provided with multiple slots spaced vertically along its length. The positions of these slots correspond to different adjustable heights of the support cantilever. When adjusting the shelf height via the support cantilever, the conductive component is engaged in the slot corresponding to the cantilever height, thus fixing the height of the conductive component. Even with shelf height adjustments, the position of the conductive component can be adjusted accordingly, allowing a single conductive component to meet the power supply needs of different shelf heights. This approach is cost-effective and structurally simple. Attached Figure Description

[0062] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0063] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0064] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0065] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0066] In related technologies, shelves can be height-adjusted via cantilever supports to divide the internal space of a refrigerator as needed. However, to ensure that shelves at different heights are illuminated, multiple power supply components are required for each height, resulting in high costs and a complex internal structure. To address these technical problems, this application proposes a refrigerator.

[0067] This embodiment provides a refrigerator for storing items at low temperatures. The refrigerator can also be a refrigerated display case, a refrigerated wine cabinet, or a freezer. The refrigerator may include a casing (not shown in the figure), which is the external shell structure of the refrigerator. It may be a rectangular column structure with internal space for accommodating other components of the refrigerator.

[0068] See Figure 1 In some embodiments, the refrigerator may include an inner liner 1 disposed within the refrigerator body. The inner liner 1 is configured to form a cooling compartment 11 with a front opening. The front of the refrigerator body is covered with an operable door to allow opening or closing of the cooling compartment 11 and accessing items within it.

[0069] In some embodiments, the refrigerator may include a refrigeration component. The refrigeration component transfers cold energy to air within an air duct assembly, providing cold air to the refrigeration compartment 11 so that cold air can be obtained within the air duct assembly. The air duct assembly may selectively communicate with the refrigeration compartment 11 to introduce air from the air duct assembly into the refrigeration compartment 11, thereby cooling the refrigeration compartment 11.

[0070] See Figure 1 In some embodiments, the air duct assembly may include an air duct cover 12 and a fan. The air duct cover 12 is disposed on the rear side of the refrigeration chamber 11, forming an air duct between the air duct cover 12 and the inner rear wall of the inner liner 1. The fan may be disposed within the air duct. The refrigeration assembly transfers cold energy into the air duct, and the fan blows the cold energy into the refrigeration chamber 11 through the air outlet on the air duct cover 12, thereby maintaining a low temperature inside the refrigeration chamber 11.

[0071] See Figure 1 In some embodiments, the refrigeration compartment 11 may include a refrigerator compartment and a freezer compartment. The air duct assembly can deliver cooling capacity to the refrigerator compartment and the freezer compartment respectively, so that the air in the air duct assembly can transfer the cooling capacity to the refrigerator compartment and the freezer compartment respectively, so as to maintain the refrigeration environment in the refrigerator compartment and the freezer compartment.

[0072] See Figure 1 The refrigeration assembly is used to release heat from inside the refrigerator to the external environment and to provide cooling to the refrigeration compartment 11 to maintain a low-temperature environment inside the refrigeration compartment 11. The refrigeration assembly includes components such as a compressor, condenser, evaporator, and capillary tubes. The compressor, condenser, capillary tubes, and evaporator are connected in sequence, and the outlet of the evaporator is connected to the inlet of the compressor, thereby forming a channel for refrigerant circulation within the compressor, condenser, capillary tubes, and evaporator. In this embodiment, the evaporator is located in the freezer compartment.

[0073] The air duct and the cooling chamber 11 are connected, allowing air to circulate between them. This transfers the cooling capacity from the air duct to the cooling chamber 11, and vice versa. The specific structure and connection of the refrigeration components are described in reference to refrigeration components in related technologies, and will not be elaborated here.

[0074] See Figure 1 and Figure 2In some embodiments, the refrigerator may include shelves 2. Shelves 2 are plate-like structures, such as flat panels, and are horizontally positioned within the refrigeration compartment 11 to support items and prevent them from sliding to one side. Shelves 2 are constructed as transparent or semi-transparent panels, such as those made of transparent glass or transparent plastic, so that light can pass through them under illumination, lighting the refrigeration compartment 11 and enhancing its ambiance and premium feel. By installing shelves 2, the space within the refrigeration compartment 11 can be divided into multiple smaller spaces, thereby fully utilizing the space and storage capacity of the refrigeration compartment 11.

[0075] In some embodiments, the refrigerator may include two support arms 3. The two support arms 3 are respectively disposed on the left and right sides of the bottom of the shelf 2, and are used to support the left and right ends of the shelf 2 respectively. By setting the support arms 3 to support the shelf 2, the height of the support arms 3 is adjustable, so that the height of the shelf 2 can be flexibly adjusted by adjusting the height of the support arms 3, and the space in the refrigeration compartment 11 can be allocated as needed.

[0076] See Figure 2 and Figure 3 In some embodiments, the refrigerator may include two hanging racks 8. The two hanging racks 8 are respectively disposed on the left and right inner walls of the inner liner 1, and the hanging racks 8 can extend along the height direction to form a long strip structure. The hanging racks 8 are provided with multiple support portions 81 spaced apart along the height direction. One end of each support portion 81 extends into the cooling compartment 11. A support cantilever 3 is detachably connected to one end of one of the support portions 81 extending into the cooling compartment 11 to fix and support the support cantilever 3. The support cantilever 3 can be selectively connected to support portions 81 of different heights, thereby achieving height adjustment of the support cantilever 3.

[0077] In some embodiments, notches may be provided on the left and right inner walls of the inner liner 1, and two brackets 8 may be integrally mounted on the notches on the corresponding sides of the inner liner, so that the support portion 81 extends into the refrigeration compartment 11. Of course, multiple through holes may also be provided on the left and right inner walls of the inner liner corresponding to the support portion 81, and the main body of the two brackets 8 may be located outside the left and right inner walls of the inner liner, with the support portion 81 on the bracket 8 extending into the refrigeration compartment 11 through the corresponding through holes.

[0078] See Figure 2 and Figure 4 In some embodiments, the support portion 81 can be a column structure that extends horizontally into the refrigeration chamber 11. A snap-fit ​​portion 31 can be provided at the rear end of the support cantilever 3, and the support portion 81 snaps into the snap-fit ​​portion 31 to support and fix the support cantilever 3. The support cantilever 3 has a support surface in the front-to-back direction, and the bottom surfaces of the left and right ends of the shelf 2 are supported on the support surface and can move back and forth along the support surface to facilitate the installation and removal of the shelf 2.

[0079] In some embodiments, the snap-fit ​​portion 31 can be a snap-fit ​​opening located at the rear end of the support cantilever 3. To improve connection stability, two snap-fit ​​portions 31 can be provided at intervals along the height direction, with the openings of the two snap-fit ​​portions 31 facing each other. When installing the support cantilever 3, two adjacent support portions 81 can be snapped into the two snap-fit ​​portions 31 respectively to restrict the support cantilever 3 from rotating along the height direction, thereby stabilizing the support shelf 2.

[0080] See Figure 4 In some embodiments, the refrigerator may include a decorative element 4. The decorative element 4 is fixed to the shelf 2 and serves a decorative purpose. The decorative element 4 may be located at the rear end of the shelf 2, or at the left and / or right end of the shelf 2. To improve aesthetics, the decorative element 4 may be elongated and extend along the edge of the shelf 2. The decorative element 4 may be transparent or semi-transparent, made of materials such as plastic or rubber, and can provide some protection and cushioning for the shelf 2.

[0081] See Figure 9 and Figure 10 In some embodiments, the decorative element 4 has a mounting slot 45 at one end facing the shelf 2. The mounting slot 45 extends along the length of the decorative element 4, and the edge of the shelf 2 is engaged in the mounting slot 45, thereby engaging and fixing with the decorative element 4 and facilitating the assembly and disassembly of both.

[0082] See Figure 9 and Figure 10 In some embodiments, the refrigerator may include a lamp body 5. The lamp body 5 is disposed on the decorative element 4, and the lamp body 5 is capable of emitting light. The light emitted by the lamp body 5 passes through the decorative element 4 and shines onto the shelf 2, thereby causing the shelf 2 to emit light and providing an illumination effect.

[0083] See Figure 10 In some embodiments, the decorative element 4 has a cavity 42 formed along its length, and the lamp body 5 is disposed within the cavity 42. The cavity wall of the cavity 42 and the bottom surface of the mounting slot 45 are arranged opposite each other, and the light-emitting surface of the lamp body 5 can face the mounting slot 45, so that the light emitted by the lamp body 5 can pass through the cavity wall of the cavity 42 and enter the mounting slot 45, thereby entering the shelf 2. The lamp body 5 can be a light strip structure that extends along the length of the decorative element 4 to improve the lighting effect and make the light output from the shelf 2 more uniform.

[0084] See Figure 10 In some embodiments, the lamp body 5 may be provided with an electrical connection terminal 51 to receive electrical energy transmitted from an external power source, thereby causing the lamp body 5 to emit light. Specifically, the electrical connection terminal 51 may be provided on the circuit board of the lamp body 5, and may be a conductive sheet or terminal provided on the circuit board for electrically connecting the circuit board and the external power source. The external power source refers to the power source located outside the refrigeration compartment 11 that belongs to the refrigerator, such as the refrigerator's power supply.

[0085] See Figure 4 and Figure 10 In this embodiment, the decorative element 4 is located at the rear end of the shelf 2. When the decorative element 4 at the rear end of the shelf 2 emits light, the light is transmitted forward into the shelf 2, thereby making the light emission of the shelf 2 more uniform and the lighting effect in the refrigeration compartment 11 better. When the user looks at the shelf 2 from the front of the refrigerator, the lamp body 5 will not be visible, which enhances the sense of luxury. The end of the decorative element 4 can also be provided with an end cap 41. The end cap 41 is used to close the two ends of the accommodating cavity 42 to make it airtight. When installing and removing the lamp body 5, the end cap 41 can be removed first to expose the two ends of the accommodating cavity 42, so as to facilitate the removal of the lamp body 5.

[0086] See Figures 2 to 4 In some embodiments, the refrigerator may include a conductive component 7. One end of the conductive component 7 is connected to a power source, and the other end abuts against an electrical connection terminal 51 to conduct electricity between the power source and the lamp body 5, enabling the lamp body 5 to emit light. The conductive component 7 may be disposed on the side wall of the refrigeration compartment 11. When the shelf 2 is installed in a predetermined position within the refrigeration compartment 11, the conductive component 7 abuts against the electrical connection terminal 51 of the lamp body 5, thus transmitting electrical energy from the power source to the lamp body 5. When the shelf 2 is removed from the refrigeration compartment 11, the conductive component 7 and the electrical connection terminal 51 disengage, the lamp body 5 is disconnected from the power source, and the lamp body 5 turns off, preventing the shelf 2 from emitting light.

[0087] See Figure 10 In some embodiments, the rear end of the decorative element 4 may be provided with an exposed hole 43 opposite to the electrical connection end 51. The electrical connection end 51 is exposed outside the decorative element 4 through the exposed hole 43. When the shelf 2 is installed in a preset position, the electrical connection end 51 can abut against the conductive component 7 to supply power to the lamp body 5.

[0088] See Figures 7 to 10 In some embodiments, the decorative element 4 may further include a sealing ring 44. The sealing ring 44 is annular and is sandwiched between the electrical connection end 51 and the inner end of the exposed hole 43. It seals the lamp body 5, allowing only the electrical connection end 51 to be exposed outside the decorative element 4, thereby preventing moisture from entering the accommodating cavity 42 and corroding the circuitry and light-emitting elements on the lamp body 5. It should be noted that the sealing ring 44 surrounds the exposed hole 43, and its two ends abut against the inner wall of the accommodating cavity 42 and the electrical connection end 51, respectively. When the conductive component 7 extends into the exposed hole 43 and abuts against the electrical connection end 51, the portion of the conductive component 7 extending into the accommodating cavity 42 is surrounded by the sealing ring 44. The sealing ring 44 may have a certain elastic deformation capability; it can be pressed against the inner wall of the accommodating cavity 42 by the electrical connection end 51, and its own elastic deformation improves the sealing performance.

[0089] In some embodiments, the side of the electrical connection terminal 51 facing the exposed hole 43 may also be provided with an anti-rust coating. The anti-rust coating improves the corrosion resistance of the electrical connection terminal 51 and prevents it from contacting external moisture and causing corrosion failure.

[0090] See Figure 4 In some embodiments, the refrigerator may include a lifting bracket 6. The lifting bracket 6 is disposed within the refrigeration compartment 11, and the lifting bracket 6 has multiple slots 61 spaced apart along the height direction. The positions of the multiple slots 61 correspond to different adjustable heights of the support cantilever 3. For example, the support cantilever 3 is connected to support portions 81 at different heights on the hanging rack 8, so that the support cantilever 3 and the shelf 2 have multiple different heights, such as a first height, a second height, and a third height. Then, the different heights of the multiple slots 61 can correspond to the first height, the second height, and the third height, respectively.

[0091] See Figure 4 In this embodiment, the conductive component 7 is movably mounted on the lifting bracket 6. The conductive component 7 can move along the height direction of the lifting bracket 6 with the shelf 2 and the supporting cantilever 3, and is engaged in the slot 61 corresponding to the height of the supporting cantilever 3. When adjusting the height of the shelf 2 via the supporting cantilever 3, the conductive component 7 is engaged in the slot 61 corresponding to the height of the supporting cantilever 3, fixing the height of the conductive component 7. Even if the height of the shelf 2 is adjusted, the position of the conductive component 7 can be adjusted accordingly, enabling one set of conductive components 7 to meet the power supply requirements of different heights of the shelf 2. This method is cost-effective and has a simpler structure.

[0092] In some embodiments, the number of slots 61 can be set to multiple, such as three, four, five or more, to be set accordingly based on the adjustable height range of the support cantilever 3.

[0093] See Figure 12 In some embodiments, a lifting channel 62 extending along the height direction can also be provided on the same side of the multiple slots 61 on the lifting bracket 6, and each slot 61 and the lifting channel 62 are connected. When the height of the support cantilever 3 is adjusted, the conductive component 7 can move from its current slot 61 to the lifting channel 62, and can move in the lifting channel 62 to the target slot 61, thereby engaging with the slot 61 corresponding to the height of the support cantilever 3, realizing flexible setting of the height of the conductive component 7. One set of conductive components 7 can meet the power supply requirements of different heights of the shelf 2.

[0094] In some embodiments, when adjusting the height of the support cantilever 3, the conductive component 7 can be directly removed from its current slot 61 and then directly inserted into the target slot 61.

[0095] See Figure 12In some embodiments, the lifting bracket 6 may include a frame body 63 and a plurality of protrusions 64. The frame body 63 extends along the height direction to form an elongated structure. The frame body 63 has an elongated hole extending along the height direction. The plurality of protrusions 64 are spaced apart in the elongated hole along the height direction. One end of the plurality of protrusions 64 is connected to one side of the elongated hole. There is a gap between the other end of the plurality of protrusions 64 and the other side of the elongated hole. This gap forms the aforementioned lifting channel 62 in the height direction, and the area between any two adjacent protrusions 64 forms the aforementioned slot 61.

[0096] See Figure 3 and Figure 7 In some embodiments, the conductive component 7 may include a housing 71. The housing 71 forms a hollow mounting cavity 711, and a mounting hole 712 communicating with the mounting cavity 711 is provided at one end of the housing 71 facing the electrical connection end 51. The mounting hole 712 and the exposed hole 43 are opposite to each other. The housing 71 constitutes the outer shell of the conductive component 7, and the housing 71 may be rectangular or cylindrical.

[0097] See Figure 7 In some embodiments, the conductive component 7 may include a conductive contact 73. The conductive contact 73 is disposed within the mounting cavity 711, and may be movably disposed within the mounting cavity 711 or fixed within the mounting cavity 711. One end of the conductive contact 73 is used for electrical connection to a power source, and the other end extends from the mounting hole 712 and abuts against the electrical connection end 51, thereby allowing electrical energy from the power source to be transferred from the conductive contact 73 to the electrical connection end 51, causing the lamp body 5 to emit light. It should be noted that the conductive contact 73 may be made entirely of a conductive material, such as copper or iron. By forming the mounting cavity 711 and placing the conductive contact 73 therein, the housing 71 itself can be non-conductive, while the conductive contact 73 conducts electricity, improving the safety of the conductive component 7.

[0098] See Figure 7 and Figure 11 In some embodiments, the conductive component 7 may further include a fixing rod 72. The fixing rod 72 is rod-shaped, with one end fixedly connected to the housing 71 and the other end engaged in the slot 61, thereby engaging the conductive component 7 in the slot 61. To change the height of the conductive component 7, the fixing rod 72 is moved from its current slot 61 to the target slot 61. The fixing rod 72 may be fixedly connected to the side of the housing 71, perpendicular to the length direction of the conductive contact 73.

[0099] See Figure 11In some embodiments, the fixing rod 72 may include an anti-rotation section 721 and a threaded section 722 connected thereto. The anti-rotation section 721 and the threaded section 722 extend in the same direction to form a rod shape. One end of the anti-rotation section 721 is fixedly connected to the housing 71, and the other end of the anti-rotation section 721 is connected to the threaded section 722. The anti-rotation section 721 is used to engage in the slot 61 to restrict its rotation, thereby ensuring that the fixing rod 72 remains stationary when engaged in the slot 61.

[0100] The cross-section of the anti-rotation section 721 can be polygonal, such as a triangle, rectangle or pentagon, so that when it is snapped into the slot 61, the polygonal structure of the anti-rotation section 721 will prevent it from rotating.

[0101] See Figure 7 In some embodiments, the end of the screw-in section 722 opposite to the anti-rotation section 721 extends out of the slot 61 and is screwed with a nut 723. By tightening the nut 723, the nut 723 can be pressed against one side of the lifting bracket 6, and the housing 71 can be pressed against the other side of the lifting bracket 6, thereby restricting the anti-rotation section 721 from coming out in the direction perpendicular to the slot 61, so that the fixing rod 72 is engaged in the slot 61. When it is necessary to adjust the position of the fixing rod 72, the nut 723 can be loosened so that the fixing rod 72 can be moved into the lifting channel 62 and into the target slot 61.

[0102] See Figure 10 and Figure 11 In some embodiments, a toggle part 713 may protrude from the outer wall of the housing 71. The toggle part 713 is exposed in the refrigeration compartment 11 for easy access by the user. The toggle part 713 is used to toggle the housing 71, causing it to move the fixing rod 72 between the slot 61 and the lifting channel 62, facilitating adjustment of the position of the conductive component 7. When adjusting the position, the user can touch the toggle part 713 to move it along the slot 61 into the lifting channel 62, then along the lifting channel 62 to the target slot 61 height, and finally push it into the target slot 61. The toggle part 713 improves the convenience of user adjustment. Of course, the user can also directly touch the housing 71 to move it.

[0103] See Figure 11 In some embodiments, the toggle part 713 may be disposed on the top of the housing 71 and near one end of the electrical connection terminal 51, making it closer to the user and easier to access. The toggle part 713 may be a protrusion structure disposed on the outer wall of the housing 71, which can be easily reached by the user's finger.

[0104] See Figure 4In some embodiments, the box 71 is located on the rear side of the decorative part 4, allowing the user to move the aforementioned toggle part 713 in the front-back direction, which is more in line with the user's adjustment habits and improves the user's ease of operation.

[0105] See Figure 1 and Figure 4 In some embodiments, a gap exists between the side of the duct cover 12 and the left and right side walls of the cooling chamber 11, forming an adjustment space 13. The lifting bracket 6 can be located on the back side of the duct cover 12, concealing it from view and preventing it from being exposed to the user, thus affecting aesthetics. To facilitate adjustment of the conductive component 7, the conductive contact 73 and the actuating part 713 can be exposed within the adjustment space 13, allowing the user to easily move the actuating part 713 in the front-back direction. Alternatively, the entire housing 71 can be exposed within the adjustment space 13, in which case the actuating part 713 and the conductive contact 73 are located within the adjustment space 13.

[0106] See Figure 1 and Figure 4 In some embodiments, when the lifting bracket 6 is disposed on the back side of the air duct cover 12, the slot 61 on the lifting bracket 6 can be opened in the front-back direction, and the lifting channel 62 is located at the front end of the slot 61. In this way, when adjusting the position of the conductive component 7, the fixing rod 72 can be controlled to move between the slot 61 and the lifting channel 62 in the front-back direction by the toggle part 713, so as to more conveniently adjust the conductive component 7 to be engaged in the corresponding slot 61.

[0107] In some embodiments, by forming an adjustment space 13, one end of the support portion 81 of the hanger 8 can be extended into the adjustment space 13, and the support cantilever 3 and the end of the support portion 81 extending into the adjustment space 13 can be detachably connected, so that the end of the support cantilever 3 connected to the hanger 8 is hidden in the adjustment space 13, thereby enhancing the aesthetics of the interior of the refrigeration room 11.

[0108] See Figure 4 In some embodiments, when the conductive contact 73 is provided, the conductive contact 73 is retractably disposed in the mounting hole 712 to abut against the electrical connection terminal 51. By making the conductive contact 73 retractable, the tightness of its abutment against the electrical connection terminal 51 can be adjusted by setting the degree of retraction of the conductive contact 73, thereby avoiding poor contact between the conductive contact 73 and the electrical connection terminal 51.

[0109] For details, see Figures 5 to 7The conductive contact 73 may include a contact base 731, a contact 732, and an elastic element 733. The contact base 731 is snapped into a mounting hole 712. A guide channel 734 is formed along the axial direction of the mounting hole 712 in the contact base 731. The guide channel 734 is open at one end facing the electrical connection end 51. The contact 732 is slidably disposed in the guide channel 734 and can move along the guide channel 734. One end of the contact 732 extends out of the mounting hole 712 and is used to abut against the electrical connection end 51. The elastic element 733 is disposed in the guide channel 734 and is connected to the contact 732. It applies an elastic force to the contact 732, causing it to move outward, so that the outer end of the contact 732 abuts against the electrical connection end 51. Simultaneously, the elastic force of the elastic element 733 ensures that the contact 732 and the electrical connection end 51 are tightly pressed together, preventing poor contact.

[0110] See Figure 7 In some embodiments, the outer contour of the contact seat 731 can correspond to the inner wall of the mounting hole 712. By setting the outer diameter of the contact seat 731 and the inner diameter of the mounting hole 712, an interference fit can be formed between the contact seat 731 and the mounting hole 712 to lock the contact seat 731.

[0111] See Figure 7 In some embodiments, the elastic element 733 can be a compression spring, a disc spring, a sheet spring, or other elastic elements. In its initial state, the outer end of the contact 732 is outside the mounting hole 712. During the backward pushing of the shelf 2 to the preset position, the outer end of the contact 732 first abuts against the electrical connection end 51 and continues to compress the elastic element 733, allowing it to store energy. When the shelf 2 is installed to the preset position, the elastic element 733 is in a compressed state, applying an outward elastic force to the contact 732, causing the contact 732 to press firmly against the electrical connection end 51. When the shelf 2 is pulled forward to remove it, the elastic element 733 gradually returns to its initial state.

[0112] See Figure 10 In some embodiments, the conductive component 7 may further include a conductive sheet 74 and a power supply terminal 75. The conductive sheet 74 and the power supply terminal 75 are disposed in the mounting cavity 711. One end of the power supply terminal 75 is connected to an external power source via a wire, and the other end is connected to the conductive sheet 74. The conductive sheet 74 is connected to the contact base 731, thereby allowing electrical energy from the power source to be transferred to the electrical connection terminal 51 through the power supply terminal 75, the conductive sheet 74, the contact base 731, and the contact 732.

[0113] See Figure 2In some embodiments, two conductive components 7 and two lifting brackets 6 can be provided. The two lifting brackets 6 are located at the left and right ends of the back side of the air duct cover 12, and the two conductive components 7 are movably mounted on the two lifting brackets 6. The left and right ends of the lamp body 5 are respectively provided with electrical connection terminals 51, and the two electrical connection terminals 51 correspond to the positive and negative terminals on the circuit board of the lamp body 5, respectively. The two conductive components 7 are respectively connected to the positive and negative terminals of the power supply to conduct the positive and negative terminals on the circuit board of the lamp body 5, so that the lamp body 5 can emit light.

[0114] In this invention, a conductive component 7 is used to connect the external power supply to the lamp body 5, thereby illuminating the lamp body 5 and thus illuminating the shelf 2. Simultaneously, a lifting bracket 6 is provided, with multiple slots 61 spaced vertically along its length. The positions of these slots 61 correspond to different adjustable heights of the support cantilever 3. When adjusting the height of the shelf 2 via the support cantilever 3, the conductive component 7 is engaged in the slots 61 corresponding to the height of the support cantilever 3, thus fixing the height of the conductive component 7. Even if the height of the shelf 2 is adjusted, the position of the conductive component 7 can be adjusted accordingly, allowing one set of conductive components 7 to meet the power supply needs of the shelf 2 at different heights. This method is cost-effective and has a simpler structure.
