Description

Technical Field

[0001] This application relates to the field of home appliances, and more specifically to a base assembly and a refrigeration device. Background Technology

[0002] In the field of home refrigeration equipment, to facilitate installation at customers' homes, the support feet are mostly rotary mechanical feet, with height adjustment achieved through threaded joints. While this type of structure can meet basic leveling requirements to a certain extent, it still has shortcomings in actual use.

[0003] On the one hand, traditional support feet are affected by the pressure of the refrigerator's own weight when under load. Under this condition, the rotational resistance increases significantly, requiring users to exert more effort to adjust the height, making the operation extremely inconvenient. Moreover, when the refrigerator needs to be moved again, readjusting the height of the feet becomes time-consuming and laborious, greatly reducing the user experience.

[0004] On the other hand, traditional support feet lack sufficient adjustment precision, making it difficult to achieve fine height adjustments, and are prone to adjustment failure due to thread wear after long-term use. Summary of the Invention

[0005] One of the purposes of this application is to provide a foot assembly to solve the technical problems of existing support feet, such as limited adjustment range, high operating resistance under load, and lack of bidirectional leveling capability, which makes it impossible to effectively solve the equipment tilting caused by complex ground inclination angles.

[0006] To achieve one of the aforementioned objectives, this application provides a foot assembly, comprising: a first fixing member; a first support member disposed in a first direction of the first fixing member; a hinge assembly including a first hinge member, a second hinge member, and a first connecting member, wherein one end of the first hinge member is hinged to the first fixing member, the other end of the first hinge member is hinged to the second hinge member via the first connecting member, the end of the second hinge member away from the first hinge member is hinged to the first support member, and the first connecting member is disposed along a second direction; an adjusting screw connected to the first connecting member and extending along a third direction, wherein the first direction, the second direction, and the third direction form an angle with each other; when the adjusting screw is adjusted in the third direction, the first connecting member moves along the third direction, the angle between the first hinge member and the second hinge member changes, and the relative position of the first fixing member and the first support member changes in the first direction.

[0007] As a further improvement of one embodiment of this application, the foot assembly further includes: a third hinge member disposed opposite to the first hinge member, a fourth hinge member disposed opposite to the second hinge member, and a second connecting member disposed opposite to the first connecting member.

The end of the fourth hinge member away from the third hinge member is hinged to the first support member, and the second connecting member is disposed along a second direction.

[0008] As a further improvement of one embodiment of this application, the hinge includes a first hinge plate, a second hinge plate, and a connecting plate connecting the first hinge plate and the second hinge plate, which are disposed opposite to each other.

[0009] As a further improvement of one embodiment of this application, the connecting member includes a connecting shaft and a fixing plate. The first hinge member has a first through hole at one end near the second hinge member, and the second hinge member has a second through hole at one end near the first hinge member. The connecting shaft passes through the first and second through holes, and at least one end is connected to the fixing plate. The adjusting screw is connected to the fixing plate. When the adjusting screw is adjusted in the third direction, the fixing plate moves in the third direction, and the connecting shaft moves accordingly.

[0010] As a further improvement of one embodiment of this application, the adjusting screw passes through the fixed plate and is threadedly connected to it. The thread on the adjusting screw extends spirally in the third direction. When adjusting the adjusting screw, the adjusting screw rotates about the third direction as the axis.

[0011] As a further improvement of one embodiment of this application, each hinge includes two hinge plates, and the connector includes two connecting shafts and a fixing plate connecting the two connecting shafts.

[0012] As a further improvement of one embodiment of this application, the foot assembly includes a first hinge assembly and a second hinge assembly disposed opposite to each other. The first hinge assembly includes a first hinge member, a second hinge member and a first connecting member. The second hinge assembly includes a third hinge member, a fourth hinge member and a second connecting member. The adjusting screw passes through the first connecting member and the second connecting member.

[0013] As a further improvement of one embodiment of this application, the foot assembly further includes a second support member, which is disposed in a first direction of the first fixing member and is away from the first support member.

[0014] As a further improvement of one embodiment of this application, the second support member includes a base and a base stud, one end of the base stud is fixedly disposed in a first direction of the first fixing member, and the other end is threadedly connected to the base.

[0015] As a further improvement of one embodiment of this application, a mounting plate extends on one side of the first fastener in the opposite direction to the first direction, and the mounting plate is provided with mounting holes.

[0016] To achieve one of the above-mentioned objectives, this application provides a refrigeration device, including the aforementioned foot assembly.

[0017] Compared with the prior art, the embodiments of this application have at least one of the following beneficial effects:

[0018] This application discloses a foot assembly. By setting an adjusting screw in the hinge connection area of ​​the first and second hinge plates, the oblique thrust generated by the axial movement of the screw can be decomposed into a tangential component that drives the hinge plate to rotate and a normal component that maintains structural stability. This efficiently converts the linear motion of the screw into the rotational motion of the hinge plate, allowing the small screw displacement to be amplified into a significant change in vertical height. This not only expands the adjustment range and reduces the operating torque, making adjustment more effortless, but also adapts to various complex ground inclination angles, effectively solving the tilting problem of refrigeration equipment caused by uneven terrain, and significantly improving the convenience of user adjustment and the stability of equipment use.

[0032] like Figure 1 As shown, one embodiment of this application provides a foot assembly 1000.

[0033] The foot assembly 1000 is a component used in various mechanical equipment, furniture, electrical appliances and other products to support, fix and adjust the position and stability of the equipment or object.

[0034] like Figure 1As shown, the foot assembly 1000 includes a first fixing member 200, a first support member 300, a hinge assembly 500, and an adjusting screw 400.

[0035] The first fastener 200 refers to a structural component fixed to the bottom of the device (e.g., a refrigerator), used to connect the device body and transfer load to the hinge assembly 500. Examples include a metal plate or a mounting base.

[0036] To facilitate the installation of the first fastener 200 with the equipment, such as Figure 2 As shown, in one embodiment, the first fastener 200 includes a first panel 21 and a mounting plate 22 extending from one side of the first panel 21 in the opposite direction to the first direction. The mounting plate 22 is provided with through holes, including a first through hole 22-1 and a second through hole 22-2.

[0037] In another embodiment, to facilitate the installation between the first fixing member 200 and the first support member 300, the first fixing member 200 further includes a first side plate 23 and a second side plate extending from opposite sides of one end of the first panel 21 along a first direction. The first side plate 23 is provided with mounting holes, including at least a first mounting hole 23-1 and a second mounting hole 23-2. The second side plate is provided with a third mounting hole symmetrical to the first mounting hole 23-1 and a fourth mounting hole symmetrical to the second mounting hole 23-2.

[0038] The mounting holes (first mounting hole 23-1, second mounting hole 23-2, third mounting hole and fourth mounting hole) provided on the first fixing member 200 are connected to one end of the first hinge member 51 and the third hinge member 53 in the hinge assembly 500, thereby realizing the connection between the first fixing member 200 and the hinge assembly 500.

[0039] The first support member 300 is disposed in a first direction of the first fixing member 200, which can be set to a direction perpendicular to the ground, i.e., a vertical direction. In other words, the first support member 300 is disposed below the first fixing member 200.

[0040] As shown in Figures 3(a) and 3(b), the first support member 300 includes a top plate 31, a first side plate 35-1 and a second side plate 35-2 extending downward from opposite sides of the top plate 31, and a bottom wheel 32 axially mounted between the first side plate 35-1 and the second side plate 35-2. The bottom wheel 32 is rotatably mounted between the first side plate 35-1 and the second side plate 35-2 by caster rivets 34. Specifically, the caster rivets 34 pass through the bottom wheel 32, the third through hole 36-1 and the fourth through hole 36-2. The bottom wheel 32 facilitates the movement of the foot assembly 1000.

[0041] Referring to Figures 3(a) and 3(b), the first support member 300 further includes a third side plate 33-1 and a fourth side plate 33-2 extending in the opposite direction (upward) of the first direction from the two sides opposite to the top plate 31. A fifth through hole 37-1 and a sixth through hole 37-2 are provided on the third side plate 33-1. A seventh through hole 37-1' symmetrical to the fifth through hole 37-1 and an eighth through hole 37-2' symmetrical to the sixth through hole 37-2 are provided on the fourth side plate 33-2.

[0042] Continue to refer to Figure 1 As shown, the first support member 300 is connected to the hinge assembly 500 by means of a connecting shaft passing through the fifth through hole 37-1, the seventh through hole 37-1', and one end of the second hinge member 52, and by means of a connecting shaft passing through the sixth through hole 37-2, the eighth through hole 37-2', and one end of the fourth hinge member 55. When the adjusting screw 400 is rotated to move it along a third direction, the distance between the first fixing member 200 and the first support member 300 is adjusted.

[0043] like Figure 1 As shown in Figures 4(a) and 4(b), the hinge assembly 500 includes a first hinge member 51, a second hinge member 52, and a first connector. One end of the first hinge member 51 is hinged to the first fixing member 200, and the other end of the first hinge member 51 is hinged to the second hinge member 52 through the first connector. The end of the second hinge member 52 away from the first hinge member 51 is hinged to the first support member 300. The first connector is arranged along a second direction.

[0044] In one specific embodiment, the second direction can be understood as the axial direction from the first connecting shaft 57-1 to the second connecting shaft 57-2, or the axial direction from the second connecting shaft 57-2 to the first connecting shaft 57-1.

[0045] Continue to refer to Figure 1 As shown in Figures 4(a) and 4(b), in one embodiment, the foot assembly 1000 further includes a third hinge 53 disposed opposite to the first hinge 51, a fourth hinge 55 disposed opposite to the second hinge 52, and a second connector disposed opposite to the first connector. One end of the third hinge 53 is hinged to the first fixing member 200, and the other end of the third hinge 53 is hinged to the fourth hinge 55 through the second connector. The end of the fourth hinge 55 away from the third hinge 53 is hinged to the first support member 300, and the second connector is disposed along a second direction.

[0046] In this embodiment, a symmetrical second set of hinge components (a third hinge component 53, a fourth hinge component 55, and a second connecting component) is added to the single set of hinge components (i.e., including a first hinge component 51, a second hinge component 52, and a first connecting component), forming a symmetrical double-hinged linkage component.

[0047] When the height of the adjustable foot assembly 1000 needs to be adjusted, the first and second connecting parts move synchronously. This not only ensures that the supporting force is evenly distributed on both sides of the first support member 300, preventing tilting or swaying caused by unilateral load, but also, the two sets of hinge assemblies are linked by the adjusting screw 400, helping the first support member 300 to remain parallel to the first fixed member 200 during height adjustment, preventing jamming or tilting during the adjustment process. In addition, the double hinge assembly forms a stable quadrilateral support frame, effectively resisting torsional loads caused by uneven ground or uneven loads on equipment (such as refrigerators).

[0048] In one embodiment, each hinge (including a first hinge 51, a second hinge 52, a third hinge 53, and a fourth hinge 55) includes two hinge plates.

[0049] Referring again to Figure 4(a), the first hinge member 51 includes a first hinge plate 5-1 and a second hinge plate 5-2 disposed opposite to each other, and a first connecting plate 5-3 connecting the first hinge plate 5-1 and the second hinge plate 5-2. Similarly, the second hinge member 52, the third hinge member 53 and the fourth hinge member 55 also include the same structural design, which will not be described in detail here.

[0050] Referring to Figures 4(a) and 4(b), in one specific embodiment, the first and second ends of the first hinge plate 5-1 and the second hinge plate 5-2 in the hinge are provided with through holes, and the two hinges are connected by passing a connecting shaft through the corresponding two through holes.

[0051] Specifically, the first hinge member 51 includes a first hinge plate 5-1 with a first through hole 5-4 at its first end, and a second hinge plate 5-2 with a second through hole 5-5 at a position corresponding to the first hinge plate 5-1; the second hinge member 52 includes a third hinge plate and a fourth hinge plate, the third hinge plate with a third through hole 5-4' at its first end, and the fourth hinge plate with a fourth through hole 5-5' at a position corresponding to the third hinge plate.

[0052] The connecting shafts include a first connecting shaft 57-1, a second connecting shaft 57-2, a third connecting shaft 57-3, and a fourth connecting shaft 57-4. The first connecting shaft 57-1 passes through a first through hole 5-4 on the first hinge plate 5-1 and a second through hole 5-4' on the second hinge plate, connecting the first hinge member 51 and the first side of the second hinge member 52; the second connecting shaft 57-2 passes through a third through hole 5-5 on the second hinge plate 5-2 and a fourth through hole 5-5' on the fourth hinge plate, connecting the first hinge member 51 and the second side of the second hinge member 52.

[0053] Similarly, the third connecting shaft 57-3 passes through the fifth through hole on the first hinge plate of the third hinge 53 and the sixth through hole on the first hinge plate of the fourth hinge, connecting the first side of the third hinge 53 and the fourth hinge 54; the fourth connecting shaft 57-4 passes through the seventh through hole on the second hinge plate of the third hinge 53 and the eighth through hole on the second hinge plate of the fourth hinge, connecting the second side of the third hinge 53 and the fourth hinge 54.

[0054] In addition, the end of the first hinge member 51 away from the second hinge member 52 is provided with two through holes, which are connected to the first mounting hole 23-1 and the third mounting hole symmetrically arranged on the first side plate 23 and the second side plate of the first fixing member 200 respectively through a connecting shaft; similarly, the end of the third hinge member 53 away from the fourth hinge member 54 is provided with two through holes, which are connected to the second mounting hole 23-2 and the fourth mounting hole symmetrically arranged on the first side plate 23 and the second side plate of the first fixing member 200 respectively through a connecting shaft.

[0055] The second hinge 52 has two through holes at the end away from the first hinge 51, which are connected to the first mounting hole 23-1 and the third mounting hole symmetrically arranged on the first side plate 23 and the second side plate of the first support 300 via a connecting shaft. Similarly, the third hinge 53 has two through holes at the end away from the fourth hinge 54, which are connected to the second mounting hole 23-2 and the fourth mounting hole symmetrically arranged on the first side plate 23 and the second side plate of the first fixing member 200 via a connecting shaft.

[0056] In one embodiment, each connector (including a first connector and a second connector) includes two connecting shafts and a fixing plate connecting the two connecting shafts.

[0057] Specifically, referring to Figures 4(a) and 4(b), the fixing plate includes a first fixing plate 58-1 and a second fixing plate 58-2; the first hinge member 51 is provided with a first through hole 5-4 and a second through hole 5-5 at one end near the second hinge member 52, and the second hinge member 52 is provided with a third through hole 5-4' and a fourth through hole 5-5' at one end near the first hinge member 51; the first connecting shaft 57-1 passes through the first through hole 5-4 and the third through hole 5-4', and its first end is connected to a through hole on one end of the first fixing plate 58-1; the second connecting shaft 57-2 passes through the second through hole 5-5 and the fourth through hole 5-5', and its second end is connected to a through hole on the other end of the first fixing plate 58-1.

[0058] Similarly, the third hinge 53 is provided with a fifth through hole and a sixth through hole 5-5 at one end near the fourth hinge 55, and the fourth hinge 55 is provided with a seventh through hole and an eighth through hole at one end near the third hinge 53. The third connecting shaft 57-3 passes through the fifth through hole and the seventh through hole, and its first end is connected to the through hole on one end of the second fixing plate 58-2. The fourth connecting shaft 57-4 passes through the sixth through hole and the eighth through hole, and its second end is connected to the through hole on the other end of the second fixing plate 58-2.

[0059] The adjusting screw 400 is connected to the first fixing plate 58-1 and the second fixing plate 58-2; when the adjusting screw 400 is adjusted in the third direction, the first fixing plate 58-1 and the second fixing plate 58-2 move in the third direction, and the connecting shaft moves accordingly.

[0060] In one specific embodiment, the adjusting screw 400 is connected to the first connector and extends along a third direction, with the first direction, the second direction and the third direction forming an angle with each other.

[0061] The adjusting screw 400 passes through the fixed plate and is threadedly connected to it. The thread on the adjusting screw 400 extends spirally in the third direction. When the adjusting screw 400 is adjusted, it rotates about the third direction as the axis.

[0062] When the height of the adjustable foot assembly 1000 needs to be adjusted, the first connecting member moves along the third direction when the adjusting screw 400 is adjusted, and the included angle between the first hinge 51 and the second hinge 52 changes accordingly. The relative position of the first fixing member 200 and the first support member 300 in the first direction changes accordingly, thereby realizing the height adjustment of the adjustable foot assembly 1000.

[0063] Referring to FIG4(b), in one specific embodiment, the foot assembly 1000 includes a first hinge assembly and a second hinge assembly disposed opposite to each other. The first hinge assembly includes a first hinge member 51, a second hinge member 52 and a first connector. The second hinge assembly includes a third hinge member 53, a fourth hinge member 54 and a second connector. The adjusting screw 400 passes through the first connector and the second connector.

[0064] The adjusting screw 400 is set horizontally, which has the following advantages compared to setting the adjusting screw 400 vertically.

[0065] First, when the adjusting screw 400 moves axially, its axial thrust acts directly on the rotational tangential of the hinge, converting linear motion into rotational motion, thus saving more effort. Second, the axial displacement of the adjusting screw 400 can be amplified into precise height changes through the hinge lever ratio, enabling fine-tuning with higher sensitivity. Third, the lateral layout allows the adjusting screw 400 to be arranged using the natural gaps between the hinge components, saving longitudinal space, reducing structural thickness, and making it suitable for the flattened design of refrigerator feet. Finally, the lateral screw can flexibly adapt to ground tilt angles that are either higher in the front and lower in the back or vice versa by synchronously controlling the angle between the two sets of hinges.

[0066] In one embodiment, such as Figure 1 and Figure 5 As shown, in one embodiment, the foot assembly 1000 further includes a second support member 600, which is disposed in a first direction of the first fixing member 200 and is away from the first support member 300.

[0067] In one specific embodiment, the second support member 600 includes a base 61 and a base stud 62. One end of the base stud 62 is fixedly disposed in a first direction of the first fixing member 200, and the other end is threadedly connected to the base 61.

[0068] In this embodiment, the first fixing member 200 is provided with a through hole 24, and one end of the foot stud 63 passes through the through hole 24 and is threaded to the fixing nut. When the foot 61 is rotated, the distance between the second support member 600 and the first fixing member 200 changes, thereby adjusting the height between the equipment and the ground.

[0069] Continue to refer to Figures 1 to 5 As shown, for the first hinge assembly, the first end of the first hinge member 51 is first connected to the first end of the second hinge member 52 via a first connector to ensure that the first connector is positioned along the second direction. The second end of the first hinge member 51 is then connected to the first end of the first fixing member 200, and the second end of the second hinge member 52 is simultaneously connected to the first end of the first support member 300.

[0070] To ensure force balance during adjustment, a third hinge 53, a fourth hinge 55, and a second connector can be installed on the other side of the first fixing member 200 and the first support member 300, using the same installation method. Furthermore, the second end of the third hinge 53 is connected to the second end of the first fixing member 200, and the second end of the fourth hinge 55 is connected to the second end of the first support member 300, thus forming a symmetrical hinge structure.

[0071] The adjusting screw 400 is then passed through the first fixing plate 58-1 and the second fixing plate 58-2 and threadedly connected to them. The adjusting screw 400 extends in a third direction, and the thread extends spirally in the third direction. Alternatively, the base stud 62 of the second support member 600 can be set in the first direction of the first fixing member 200, and the base 61 can be threadedly connected to the other end of the base stud 62.

[0072] When it is necessary to adjust the height or level of the equipment, the operator rotates the adjusting screw 400 around a third axis. Since the adjusting screw 400 is threadedly connected to the fixed plate, rotating the adjusting screw 400 will cause the fixed plate to move along a third axis, thereby causing the connecting shaft to move accordingly.

[0073] The movement of the connecting shaft will change the included angle between the first hinge 51 and the second hinge 52 (if there is a symmetrical hinge structure, the included angle between the third hinge 53 and the fourth hinge 55 will also change synchronously), thereby changing the relative position of the first fixing member 200 and the first support member 300 in the first direction.

[0074] If the base assembly 1000 is equipped with the second support member 600, the height of the second support member 600 can be finely adjusted by rotating the base foot 61 and adjusting the relative position between the base stud 62 and the base foot 61. Through the above adjustment operations, the height and level of the equipment can be adjusted to meet different installation requirements and ground conditions.

[0075] like Figure 6 As shown, for example, the foot assembly 1000 can be installed at the first and second ends of the bottom of the refrigerator by means of bolts, welding, etc. For example, it can be installed at the left and right ends of the refrigerator near the door. When the ground on which the refrigerator is located is uneven, the foot assembly 1000 can be adjusted to make the refrigerator stand in a horizontal position.

[0076] Specifically, by rotating the adjusting screw 400, the included angle between the first hinge and the second hinge changes, thereby changing the distance between the first fixing member 200 and the first support member 300.

[0077] After the first support member 300 is adjusted to its position, it can be further adjusted and positioned by rotating the base 32. When the first support member 300 is in contact with the bearing surface (such as the ground), it facilitates the movement of the load on it; when the second support member 600 is in contact with the bearing surface (such as the ground), it fixes the load on it, preventing movement after leveling. Moreover, the height of the first support member 300 is adjustable, and the adjustment range of the base assembly 1000 is not restricted by the first support member 300, so as to meet the height adjustment of different bearing surfaces.

[0078] This application also provides a refrigeration device, which includes the aforementioned foot assembly. In this embodiment, the foot assembly is fixed to the front side of the refrigerator by a mounting plate 22, thereby solving the leveling problem when the bearing surface is higher in the front and lower in the back, preventing the refrigerator from tilting backward and affecting the user's normal use.

[0079] In this embodiment, when the refrigerator is placed on the ground, the first support 200 and the second support 600 (if any) may tilt due to uneven ground when they contact the ground. Rotating the adjusting screw 400 causes the screw to move along a third direction due to the thread action, pushing the connecting piece and the hinge shaft to move synchronously. The movement of the connecting piece forces the first hinge and the second hinge to move relative to each other around the hinge axis (second direction), changing their included angle. If it is a double hinge assembly, the two sets of hinges move synchronously, and the change in the included angle of the hinges is converted into the lifting and lowering of the first support 200 in the vertical direction (first direction), thereby adjusting the height of the equipment. At the same time, rotating the base stud 62 finely adjusts the height of the second support 600, which works with the hinge assembly 500 to achieve all-round level calibration. After adjustment to level, the threads self-lock or are fixed by nuts to ensure stability.

[0080] By utilizing the force-saving transmission of the inclined screw and the lever amplification of the hinge, high-precision, low-resistance height adjustment is achieved. The double-hinged design further ensures the stability of adjustment, and the multiple support points are suitable for complex ground conditions.

[0081] In summary, this application provides a foot assembly and a refrigeration device. By setting an adjusting screw in the hinge connection area of ​​the first and second hinge plates, the oblique thrust generated by its axial movement can be decomposed into a tangential component driving the hinge plate to rotate and a normal component maintaining structural stability. This efficiently converts the linear motion of the screw into the rotational motion of the hinge plate, amplifying the minute screw displacement into a significant change in vertical height. This not only expands the adjustment range and reduces the operating torque, making adjustment more effortless, but also adapts to various complex ground inclination angles, effectively solving the tilting problem of refrigeration equipment caused by uneven terrain, and significantly improving the convenience of user adjustment and the stability of equipment use.
