Description

Technical Field

[0001] This application relates to the field of handles, specifically providing a handle, a moving mechanism, and a household appliance system. Background Technology

[0002] Handles are widely used in various equipment and components as common load-bearing parts in daily life and industrial production. One typical application is the handle of a moving mechanism, often located at the bottom of household appliances to facilitate movement by pushing or pulling, allowing users to clean or reposition the appliances. In addition, handles can also be used as operating levers on mechanical equipment or in material handling carts.

[0003] Generally, a handle consists of two main parts: a frame and a grip. The frame, as the supporting structure, needs to be strong enough to withstand the force applied by the user, while the grip is fitted onto the frame and comes into direct contact with the user's hand to improve grip comfort. However, in actual use, this structure is prone to the problem of the grip detaching. This is mainly because, with prolonged use, repeated gripping and applying force can gradually loosen the connection between the grip and the frame. A detached grip not only affects the user experience, causing discomfort, but may also lead to slippage due to an unstable grip, resulting in safety hazards such as injury.

[0004] Accordingly, there is a need in the field for a new handle, moving mechanism, and household appliance system to address the aforementioned problems. Utility Model Content

[0005] This application aims to solve the aforementioned technical problem, namely, the problem that the handle of the existing handle is prone to falling off.

[0006] In a first aspect, this application provides a handle, comprising: a frame, the frame including a middle plate, a first plate and a second plate, the first plate and the second plate being bent in the same direction from opposite sides of the middle plate; a handle, the handle having a receiving cavity, the frame being at least partially disposed in the receiving cavity such that the handle covers at least part of the outer side of the frame, the receiving cavity being provided with a first clamping rib, the first clamping rib and a first inner wall of the handle forming a first clamping groove, the first plate being disposed in the first clamping groove such that the first inner wall and the first clamping rib clamp the first plate.

[0007] In the above-mentioned optional technical solution for the handle, the receiving cavity is further provided with a second clamping rib, the second clamping rib and the second inner wall of the handle form a second clamping groove, and the second plate is disposed in the second clamping groove so that the second inner wall and the second clamping rib clamp the second plate.

[0008] In the above-mentioned optional technical solutions for the handle, the receiving cavity is configured as a hollow cavity so that the handle covers the entire circumference of the skeleton.

[0009] In the above-mentioned optional technical solutions for the handle, the handle has a closed end that closes one side of the hollow cavity, and the closed end is connected to or has a gap with the end face of the skeleton.

[0010] In the above-mentioned optional technical solutions for the handle, the handle is provided with concave and convex portions; and / or the frame is made of metal, and the handle is made of plastic, rubber or silicone.

[0011] In the above-mentioned optional technical solutions for the handle, the handle is suitable for a moving mechanism at the bottom of a household appliance. The moving mechanism includes a base body, a moving bracket, and a roller assembly. The moving bracket is movably disposed at the bottom of the base body, and the roller assembly is vertically adjustable relative to the base body. The moving mechanism is configured such that when the moving bracket moves along a first direction, the roller assembly can be lowered and used to support the household appliance; when the moving bracket moves along a second direction opposite to the first direction, the roller assembly is allowed to rise and retract. A first segment of the frame is disposed in the receiving cavity, and a second segment of the frame extends out of the receiving cavity. The second segment has a first connecting portion and a second connecting portion. The first connecting portion is hinged to the base body, and the second connecting portion is drivenly connected to the moving bracket to selectively move the moving bracket along the first direction or the second direction.

[0012] In the above-mentioned optional technical solutions for the handle, a first shaft is provided on one of the second connecting part and the movable bracket, and a guide hole is provided on the other of the second connecting part and the movable bracket. The first shaft is rotatably disposed in the guide hole and is movable in the guide hole.

[0013] In the above-mentioned optional technical solutions for the handle, the guide hole is provided on the movable bracket, and both the first plate and the second plate are provided with protrusions with first shaft holes. The first shaft holes on the protrusions of the first plate and the second plate are used for connecting the first shaft; and / or both the first plate and the second plate are provided with second shaft holes on the side opposite to the handle. The second shaft holes on the first plate and the second plate are used for connecting the second shaft so as to be hinged to the base body through the second shaft.

[0014] On the other hand, this application also provides a moving mechanism that includes the handle described in any of the above embodiments.

[0015] On the other hand, this application also provides a home appliance system, which includes a home appliance and the aforementioned moving mechanism, the moving mechanism being disposed at the bottom of the home appliance.

[0016] Those skilled in the art will understand that the handle of this application includes a frame and a handle. The frame includes a middle plate, a first plate, and a second plate. The first plate and the second plate are respectively bent from opposite sides of the middle plate in the same direction. The handle has a receiving cavity. At least part of the frame is disposed in the receiving cavity so that the handle covers at least part of the outer side of the frame. A first clamping rib is provided in the receiving cavity. The first clamping rib and the first inner wall of the handle form a first clamping groove. The first plate is disposed in the first clamping groove so that the first inner wall and the first clamping rib clamp the first plate.

[0017] The frame consists of a middle plate and two plates, a first plate and a second plate, bent in the same direction from opposite sides. This structure provides the basis for a tight fit between the frame and the handle. The handle's receiving cavity first forms a covering constraint on the outside of the frame. Then, when the first plate is positioned in the first clamping groove, the first inner wall and the first clamping rib exert a stable clamping force on the first plate. This clamping force works in conjunction with the bending shape of the frame and the covering effect of the receiving cavity: the covering of the receiving cavity restricts the relative displacement between the handle and the frame, while the clamping force further strengthens the tightness of the connection. Under the combined effect of these structures, the loosening tendency caused by repeated gripping by the user is effectively resisted, thus preventing the handle from detaching from the frame and significantly improving the stability and safety of the handle.

Detailed Implementation

[0027] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

"Front" refers to the direction near the door, based on the horizontal direction of the household appliance in its use state, and "rear" refers to the direction near its back panel, based on the horizontal direction of the household appliance in its use state. The width direction is the direction from one side panel to the other of the household appliance. Furthermore, it should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] To address the issue of existing handles easily detaching, such as Figures 1 to 5As shown, this application provides a handle 100, which includes a frame 110 and a handle 120. The frame 110 includes a middle plate 111, a first plate 112, and a second plate 113. The first plate 112 and the second plate 113 are respectively bent from opposite sides of the middle plate 111 in the same direction. The handle 120 has a receiving cavity 121, and the frame 110 is at least partially disposed in the receiving cavity 121 so that the handle 120 covers at least part of the outer side of the frame 110. A first clamping rib 122 is provided in the receiving cavity 121. The first clamping rib 122 and the first inner wall 124 of the handle 120 form a first clamping groove. The first plate 112 is disposed in the first clamping groove so that the first inner wall 124 and the first clamping rib 122 clamp the first plate 112. The frame 110 can be made of metal, and the handle 120 can be made of plastic, rubber, or silicone.

[0030] The frame 110 consists of a middle plate 111 and a first plate 112 and a second plate 113 that bend in the same direction from opposite sides. This structure provides the basis for its tight fit with the handle 120. The receiving cavity 121 of the handle 120 first forms a covering constraint on the outside of the frame 110. On this basis, when the first plate 112 is placed in the first clamping groove, the first inner wall 124 and the first clamping rib 122 will form a stable clamping force on the first plate 112. This clamping force works in conjunction with the bending shape of the frame 110 and the covering effect of the receiving cavity 121: the covering of the receiving cavity 121 restricts the relative displacement between the handle 120 and the frame 110, and the clamping force further strengthens the tightness of the connection between the two. Under the combined action of these structures, it can effectively resist the loosening tendency caused by repeated gripping and force application by the user, thereby preventing the handle 120 from falling off the frame 110, and significantly improving the stability and safety of the handle 100 in use.

[0031] In one possible implementation, the cavity 121 is further provided with a second clamping rib 123. The second clamping rib 123 and the second inner wall 125 of the handle 120 surround each other to form a second clamping groove. The second plate 113 is disposed in the second clamping groove so that the second inner wall 125 and the second clamping rib 123 clamp the second plate 113.

[0032] The second clamping rib 123 added inside the receiving cavity 121 and the second inner wall 125 form a second clamping groove. When the second plate 113 is placed in this groove, the second inner wall 125 and the second clamping rib 123 will form a stable clamping on the second plate 113. This structure forms a reliable constraint from the other side of the frame 110. By clamping the second plate 113, it can form a stable connection with the clamping of the first plate 112, which is subjected to bidirectional force, further reducing the relative movement space between the handle 120 and the frame 110, and enhancing the anti-loosening ability of the overall structure of the handle 100.

[0033] In one possible implementation, the receiving cavity 121 is configured as a hollow cavity so that the handle 120 covers the entire circumference of the frame 110. This complete circumferential coverage increases the contact area between the handle 120 and the frame 110, forming a circumferential constraint on the frame 110 from all directions, making the connection between the two more secure and tighter. Simultaneously, in conjunction with the bidirectional clamping of the first and second clamping grooves, the circumferential force generated by the complete circumferential coverage and the clamping forces on both sides work together to comprehensively enhance the connection strength between the handle 120 and the frame 110 from the overall perspective to the local level, maximizing the prevention of the handle 120 from detaching.

[0034] In one possible implementation, the handle 120 has a closed end 126 on one side of the closed hollow cavity, which is connected to or spaced from the end face of the frame 110. When the closed end 126 is connected to the end face of the frame 110, it can effectively limit the frame 110 axially, further restricting the axial movement of the frame 110 within the receiving cavity 121, and preventing loosening of the connection due to axial movement of the frame 110 relative to the handle 120 during long-term use. Even if there is a gap between the closed end 126 and the end face of the frame 110, it can still provide a certain axial blocking effect, reducing damage caused by direct collision of external objects with the end face of the frame 110.

[0035] The specific method of the handle 120 covering the skeleton 110, the first plate 112 being disposed in the first clamping groove, and the second plate 113 being disposed in the second clamping groove can be by injection molding process. That is, the skeleton 110 is first placed in the mold, and then molten raw material of the handle 120 material (such as rubber, silicone or soft plastic) is injected into the mold. After the raw material cools and solidifies, the handle 120 and the skeleton 110 form a tight covering bond. At this time, the hollow cavity can completely fit the outer periphery of the skeleton 110, achieving seamless covering of the entire circumference of the skeleton 110. Furthermore, the first inner wall 124 and the first clamping rib 122 clamp the first plate 112, and the second inner wall 125 and the second clamping rib 123 clamp the second plate 113. However, this is not a limitation. For example, an interference fit assembly method can also be used, where the inner diameter of the hollow cavity of the handle 120 is smaller than the outer circumference of the frame 110, the first plate 112 is smaller than the size of the first clamping groove, and the second plate 113 is smaller than the size of the second clamping groove. External force is used to press the frame 110 into the hollow cavity, the first plate 112 into the first clamping groove, and the second plate 113 into the second clamping groove. The elastic deformation of the handle 120 material achieves tight coverage and clamping, ensuring no significant gap between the two. Alternatively, bonding can also be used. As long as the handle 120 can cover the frame 110, the first inner wall 124 and the first clamping rib 122 can clamp the first plate 112, and the second inner wall 125 and the second clamping rib 123 can clamp the second plate 113, these possible adjustments do not deviate from the principles of this application and are all within the protection scope of this application.

[0036] As one possible implementation, the handle 120 is provided with a recessed portion 127, which may be in the shape of a pulsator, so that the user can hold it.

[0037] As one possible implementation method, such as Figure 6 As shown, the handle 100 of this application is adapted to the moving mechanism 200 at the bottom of the household appliance 400. The moving mechanism 200 of this application will be described in detail below.

[0038] The household appliance 400 in this application can be a washing machine, washer-dryer, or refrigerator, etc. The moving mechanism 200 includes a base body 210, a moving bracket 220, and a roller assembly 230. The moving bracket 220 is movably disposed at the bottom of the base body 210, and the roller assembly 230 is vertically movable relative to the base body 210. The moving mechanism 200 is configured such that when the moving bracket 220 moves along a first direction, the roller assembly 230 can be lowered and support the household appliance 400; when the moving bracket 220 moves along a second direction opposite to the first direction, the roller assembly 230 can be raised and retracted. The first section of the frame 110 is disposed in the receiving cavity 121, and the second section of the frame 110 extends out of the receiving cavity 121. The second section has a first connecting part 114 and a second connecting part 115. The first connecting part 114 is hinged to the base body 210, and the second connecting part 115 is drivenly connected to the moving bracket 220 to drive the moving bracket 220 to selectively move along the first direction or the second direction.

[0039] Possibly, one of the second connecting part 115 and the movable bracket 220 is provided with a first shaft, and the other of the second connecting part 115 and the movable bracket 220 is provided with a guide hole (which can be an elongated hole). The first shaft is rotatably disposed in the guide hole and is movable within the guide hole. A limiting block may be provided at the end of the first shaft to prevent the first shaft from dislodging from the guide hole.

[0040] Specifically, a guide hole is provided on the movable bracket 220, and both the first plate 112 and the second plate 113 are provided with protrusions (i.e., second connecting portions 115) with first shaft holes 116. The first shaft holes 116 on the protrusions of the first plate 112 and the second plate 113 are used for connecting to the first shaft. In addition, it is possible that both the first plate 112 and the second plate 113 are provided with second shaft holes 117 on the side opposite to the handle 120. The second shaft holes 117 on the first plate 112 and the second plate 113 are used for connecting to the second shaft so as to hinge to the base body 210 through the second shaft.

[0041] The protrusions of the first plate 112 and the second plate 113 are connected to the first shaft through the first shaft hole 116, which can evenly distribute the force on the first shaft to the two plates, avoid deformation or damage to a single plate due to excessive force, and ensure the reliability of the transmission connection with the moving bracket 220. When hinged to the base body 210, the two plates are connected to the second shaft through the second shaft hole 117, which can make the force at the hinge point more balanced, enhance the stability of the connection between the handle 100 and the base body 210, and reduce the loosening of the connection caused by force concentration during long-term use.

[0042] It should be noted that the above configuration is not restrictive. As long as the first connecting part 114 of the handle 100 is hinged to the base body 210 and the second connecting part 115 is driven to the movable support 220 to selectively move the movable support 220 along the first or second direction, the specific configuration can be adjusted. For example, the first connecting part 114 is hinged to the base body 210, and the second connecting part 115 is driven to the movable support 220 through a first connecting rod and a second connecting rod. For instance, one end of the first connecting rod is hinged to the movable support 220, the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the second connecting part 115. These possible adjustments do not deviate from the principles of this application and are all within the scope of protection of this application.

[0043] Continue to refer to Figure 6The moving mechanism 200 of this application includes a base, which includes a base body 210. The base body 210 includes a plate and a first upright plate and a second upright plate disposed on both sides in the width direction of the plate, such that the first upright plate, the plate, and the second upright plate form a guide groove. The moving bracket 220 is partially located in the guide groove. The roller assembly 230 includes a roller 231 and a connecting arm 232. One end of the connecting arm 232 is rotatably connected to the base body 210 via a connecting shaft, and the other end of the connecting arm 232 is rotatably connected to the roller 231. The movable support 220 includes a pushing section located between the connecting shaft and the base body 210. The pushing section has a third and a fourth upright plate on both sides in the width direction, forming a moving groove. The moving groove and the guide groove are in contact with each other, specifically, the pushing section is in contact with the bottom of the guide groove. The third and fourth upright plates are in contact with the side walls (first and second upright plates) of the guide groove, respectively, to ensure stable movement of the movable support 220 and prevent swaying. The third and fourth upright plates of the moving groove each have a first strip-shaped hole along the moving direction. Both ends of the connecting shaft pass through these first strip-shaped holes and connect to the side walls of the guide groove, ensuring smooth movement of the movable support 220. The movable support 220 has a pushing structure, which is used to push the roller assembly 230 down when the movable support 220 moves in the first direction, and to abut against the roller assembly 230 when the roller assembly 230 is down, so that the roller assembly 230 supports the household appliance 400 and facilitates the movement of the household appliance 400 by rotating the roller 231.

[0044] Possibly, the connecting arm 232 includes a first connecting arm and a second connecting arm, which are spaced apart and both connected to the roller shaft. The ends of both the first and second connecting arms away from the roller 231 are connected to the connecting shaft. The roller 231 may be located between the first and second connecting arms, or there may be at least two rollers 231, located on the outer sides of the first and second connecting arms, respectively. The first and second connecting arms may be fixedly connected to the connecting shaft, which is rotatably connected to the base body 210. Alternatively, the first and second connecting arms may be rotatably connected to the connecting shaft, which is fixedly connected to the base body 210. These possible adjustments do not deviate from the principles of this application and are all within the scope of protection of this application.

[0045] It should be noted that the specific implementation of the roller assembly 230 is not fixed. As long as the roller assembly 230 is rotatably mounted on the base body 210 via the connecting shaft, its specific implementation can be adjusted. For example, one of the first connecting arm and the second connecting arm can be omitted.

[0046] This application does not limit the specific form of the driving structure described above. Two possible implementation methods are described below as examples.

[0047] In a first possible implementation, the pushing structure is a wedge-shaped block with an inclined surface facing the roller assembly 230. One end of the inclined surface is connected to the movable support 220, so that when the movable support 220 moves in a first direction, the inclined surface can extend into the gap between the roller assembly 230 and the movable support 220, thereby guiding the roller assembly 230 to rotate away from the movable support 220. When the movable support 220 moves in the opposite direction, the wedge-shaped block moves away from the roller assembly 230, allowing the roller assembly 230 to retract.

[0048] In a second possible implementation, the push structure is configured as an inclined groove on the third and fourth upright plates. The opposite side walls of the guide groove each have vertically oriented openings. The two ends of the roller shaft are respectively located in the inclined grooves on both sides and in the openings on both sides of the guide groove. In this case, the roller 231 can be located outside the guide groove, and the first and second connecting arms can be located inside the moving groove. This configuration allows the roller assembly 230 to gradually descend and unfold under the influence of the inclined walls of the inclined groove when the moving support 220 moves in the first direction, until the roller 231 contacts the ground. When the moving support 220 moves in the opposite direction, the inclined walls of the inclined groove move away from the roller assembly 230, allowing the roller assembly 230 to retract.

[0049] Understandably, the sidewall of the guide groove has a vertically oriented opening, meaning the opening extends from the side of the guide groove closest to its bottom to the side furthest from the bottom. In other words, after the moving mechanism 200 is installed at the bottom of the household appliance 400, and the household appliance 400 is in its normal placement state, the opening is vertically oriented.

[0050] The working principle of the mobile mechanism 200 of this application is described below.

[0051] When the roller assembly 230 needs to rise and retract, the handle 100 is rotated at a certain angle. The moving groove, guided by the guide groove, moves smoothly in the second direction (e.g., backward), pushing the structure away from the roller assembly 230, allowing the roller assembly 230 to rise and retract until the base assembly of the household appliance 400 contacts the ground. When the roller 231 needs to descend to move the household appliance 400, the handle 100 is rotated at a certain angle in the opposite direction. This causes the moving groove, guided by the guide groove, to move smoothly in the first direction (e.g., forward), causing the first and second connecting arms of the roller assembly 230 to rotate away from the base body 210. The roller 231 descends and contacts the ground, pushing the structure against the roller assembly 230, which then supports the household appliance 400.

[0052] As one possible implementation, a double torsion spring is fitted onto the connecting shaft, with its two free ends abutting against the movable bracket 220. This restricts the axial displacement of the connecting shaft. By physically constraining the axial degree of freedom of the connecting shaft, the roller assembly 230 is ensured to maintain the correct attitude and relative position even when subjected to lateral forces, preventing the roller assembly 230 from being difficult to retract due to lateral deviation.

[0053] Possibly, the base also includes a first mounting plate 211 and a second mounting plate 212, which are located at opposite ends along the length of the base body 210. The first mounting plate 211 and the second mounting plate 212 are preferably integrally formed with the base body 210. The first mounting plate 211 and the second mounting plate 212 are also located on the same side along the width of the base body 210. The first mounting plate 211 is used to mount the first foot 310 of the household appliance 400, and the second mounting plate 212 is used to mount the second foot 320 of the household appliance 400.

[0054] Possibly, both the second foot 320 and the first foot 310 are fixed feet, facilitating upgrades to existing household appliances 400. The first foot 310 can be a front foot, and the second foot 320 a rear foot. It's understood that a fixed foot refers to a foot that cannot be extended or retracted. Specifically, the fixed foot includes a support pad and a threaded rod. One end of the threaded rod is connected to one side of the support pad, and the other end passes through the corresponding mounting plate and connects to the bottom of the household appliance 400. The support pad is used to contact a reference surface such as the ground. A fastening nut can be fitted onto the threaded rod.

[0055] Alternatively, the second foot 320 and / or the first foot 310 may be telescopic feet, used to automatically level the household appliance 400, specifically as the second foot 320 being a telescopic foot. When the user needs to move the household appliance 400, the roller assembly 230 of the moving mechanism 200 can be lowered, thereby moving the household appliance 400 via the moving mechanism 200. After stopping the movement, the roller assembly 230 of the moving mechanism 200 can be raised and retracted. After the telescopic feet contact the ground, a leveling operation is performed, ensuring that the device immediately returns to a stable state without any additional operation, enabling the household appliance 400 to seamlessly switch between the moving state and the foot-supported state.

[0056] Possibly, the first mounting plate 211 has a first mounting hole, through which the first foot 310 of the household appliance 400 passes and is fixed to the bottom of the household appliance 400. As one possible implementation, the second mounting plate 212 has a second slotted hole for mounting the second foot 320. The second slotted hole is positioned along the moving direction of the moving groove. The second foot 320 has a threaded post that passes through the second slotted hole and is screwed into the base plate of the household appliance 400.

[0057] With the moving mechanism 200 positioned along the front-to-back direction of the household appliance 400, the aforementioned arrangement allows the position of the second foot 320 to be adjustable relative to the household appliance 400, enabling adjustments to the foot position of household appliances 400 at different depths. This is applicable to different models of household appliances 400 and facilitates the modification and upgrading of existing household appliances 400. Specifically, a fixing hole corresponding to the position of the strip-shaped hole can be pre-drilled on the base plate of the household appliance 400 to facilitate the installation of the threaded post on the second foot 320.

[0058] The present application includes multiple moving mechanisms 200, but two are used as an example. The two moving mechanisms 200 are located on opposite sides of the base plate of the household appliance 400, and can both be arranged along the front-rear direction of the household appliance 400. Each moving mechanism 200 can have multiple roller assemblies 230, but two are used as an example. The two roller assemblies 230 are spaced apart and are rotatably connected to the guide groove via connecting arms. The pushing section has a pushing structure at the corresponding position of each roller assembly 230.

[0059] This application does not limit the specific form of the telescopic foot; it can be a hydraulic foot, with two hydraulic feet connected by a pipeline. These two hydraulic feet can be respectively mounted on two moving mechanisms 200. Hydraulic feet are well known, and their specific structure will not be described in detail. It should be noted that although this application uses a hydraulic foot as an example for describing the telescopic foot, this is not intended to limit the scope of protection of this application. As long as the telescopic foot has an automatic leveling function, it can be any existing or future structure.

[0060] Possibly, the bottom of the household appliance 400 of this application has a protruding first extension edge. This first extension edge can be located near the door of the household appliance 400, i.e., the front side of the household appliance 400, and is positioned along the width direction of the household appliance 400. The first extension edge can be an extension edge extending downwards from the bottom of the front panel of the household appliance 400, etc. The bottom plate has a downward-extending second extension edge, and the first and second extension edges are connected by a connector, such as a bolt or a clip, thereby enhancing the structural strength of the household appliance 400 and improving its overall stability. The first and second extension edges can also provide protection for components at the bottom of the household appliance 400, effectively preventing damage or scratches to the bottom structure of the household appliance 400 from external objects, and can also serve as decorative panels, etc.

[0061] Possibly, the base body 210 has a protrusion protruding downward on one side of the first mounting plate 211 in the length direction, so that the top of the base body 210 forms a groove corresponding to the position of the protrusion. The groove passes through both ends in the width direction of the household appliance 400 to accommodate the first and second extension sides described above, so as to ensure that the base is horizontally installed at the bottom of the household appliance 400 and to avoid the movement of the moving mechanism 200 being obstructed due to tilting or instability.

[0062] In this case, the movable bracket 220 also has a bent section that extends beyond the protrusion and connects to the handle 100, so that the handle 100 can selectively drive the movable bracket 220 to move in either a first direction or a second direction, thereby driving the movable bracket 220 to reciprocate. Specifically, the bent section includes a first extension section and a second extension section. The first extension section bends away from the push section in a direction away from the base, and the second extension section bends from the first extension section toward the protrusion and extends beyond the protrusion. The second connecting portion 115 of the handle 100 is connected to the portion of the second extension section that extends beyond the protrusion, so as to facilitate the fit between the movable bracket 220 and the base body 210 and ensure horizontal installation.

[0063] It should be noted that although the roller assembly 230 in this application is described using the roller 231 and connecting arm as an example, this is not intended to limit the scope of protection of this application. For example, the roller assembly 230 includes a roller 231 and a roller shaft. The roller 231 is rotatably mounted on the movable bracket 220 via the roller shaft. A guide wedge is provided on the base, and a guide groove is provided on the movable bracket 220. The guide wedge is located in the guide groove. When the movable bracket 220 moves in the first direction, under the guidance of the guide wedge, the movable bracket 220 descends as a whole, and the roller 231 contacts the ground to support the household appliance 400. These possible adjustments do not deviate from the principles of this application and are all within the scope of protection of this application.

[0064] On the other hand, this application also provides a household appliance system, which includes the moving mechanism 200 of any of the above embodiments, and also includes a household appliance 400, with a base body 210 mounted on the bottom of the household appliance 400. It should be noted that the above-described mounting on the bottom of the household appliance 400 can refer to mounting on a base plate at the bottom of the household appliance 400.

[0065] It should be noted that the above embodiments are only used to illustrate the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above structure so that this application can be applied to more specific application scenarios.

[0066] For example, as an alternative implementation, the sidewall of the guide groove can protrude beyond the sidewall of the moving groove, and the connecting shaft can extend beyond the sidewall of the moving groove and connect to the sidewall of the guide groove. In this case, the first strip hole can be omitted. These adjustments do not deviate from the principles of this application and are all within the protection scope of this application.

[0067] For example, as an alternative implementation, at least one of the following can be omitted: the third upright plate, the fourth upright plate, the first upright plate, the second upright plate, the first mounting plate 211, the second mounting plate 212, the groove, etc.

[0068] For example, as an alternative implementation, the base body 210 may not have a guide groove, and the guide groove may be replaced by a straight plate structure. Columns are provided on opposite sides of the straight plate structure, and the connecting arm of the roller assembly 230 is rotatably connected to the column through a connecting shaft.

[0069] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
