[0026] The present application will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments are not intended to limit the present application, and any structural, method, or functional changes made by those skilled in the art based on the embodiments are included in the scope of the present application.

[0027] The terms such as "upper", "above", "lower", "below", and the like used herein to indicate spatial relative positions are used to describe the relationship of one unit or feature with respect to another unit or feature as shown in the drawings for the purpose of convenience of explanation. The spatial relative position terms can be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings. For example, if the device in the drawings is turned upside down, the unit described as being "below" or "under" the other unit or feature will be "above" the other unit or feature. Thus, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatial-related descriptions used herein are interpreted accordingly.

[0028] Referring to Fig. 1, an embodiment of the present application provides a sliding connection device 100, and referring to Fig. 5, an embodiment of the present application provides a household appliance device 1000. The household appliance device 1000 includes an embedded household appliance 200, such as a refrigerator, and a cabinet 300 for accommodating the embedded household appliance 200, the household appliance 200 including a first door body 210 and a cabinet, the first door body 210 being used to open or close the cabinet.

[0029] The cabinet 300 includes a second door body 310, the second door body 310 covering the first door body 210, and the sliding connection device 100 being used to slidingly connect the first door body 210 to the second door body 310, so that when the second door body 310 is opened, the first door body 210 can be driven to open, thereby opening the cabinet of the household appliance 200.

[0030] Referring to Figs. 2-4, the sliding connection device 100 includes a base 20 used to cooperate with the first door body 210, and a sliding member 10 used to cooperate with the second door body 310, the base 20 being slidingly connected to the sliding member 10. The sliding member 10 and the base 20 are disposed between the first door body 210 and the second door body 310 to slidingly connect the first door body 210 and the second door body 310.

[0031] The sliding connecting device 100 further comprises a first fastener 40 for fixing the sliding piece 10 to the second door body 310, and a second fastener 50 for fixing the base 20 to the first door body 210. In this way, the sliding piece 10 is fixed relative to the second door body 310, the base 20 is fixed relative to the first door body 210, and the sliding piece 10 and the base 20 slide relative to each other, thereby driving the first door body 210 and the second door body 310 to slide relative to each other.

[0032] Specifically, the first fastener 40 and the second fastener 50 are both screws, and each comprises a screw cap and a screw rod. In specific embodiments, the first fastener 40 and the second fastener 50 can be different in size and structure, as long as they can achieve the function of fixed connection through the screw rod.

[0033] The sliding piece 10 comprises a positioning portion 13 for positioning cooperation with the second door body 210, and a mounting portion 11 for assembly fixation with the second door body 210. In this way, the sliding piece 10 itself can be positioned and cooperated with the second door body 210 and fixedly assembled, simplifying the positioning process and facilitating operation.

[0034] The sliding piece 10 comprises a connecting structure 16 connecting the positioning portion 13 and the mounting portion 11, and the connecting structure 16 is thinner than the positioning portion 13 and the mounting portion 11, and is configured to be elastically rotatable.

[0035] The sliding piece 10 is a sheet-shaped body, and the mounting portion 11, the connecting structure 16, and the positioning portion 13 are arranged in sequence. The connecting structure is configured to be rotatable, so that the positioning portion 13 can rotate relative to the mounting portion 11 after completing the positioning function to cover part of the mounting portion 11, serving as a cover. Here, after elastic rotation, the mounting portion 11 is still in a connected state with the positioning portion 13.

[0036] In other embodiments, the connecting structure 16 is configured to be breakable, and can be broken after elastic rotation, so that the positioning portion 13 and the mounting portion 11 are in a separated state. The positioning portion 13 and the mounting portion 11 are separable through the connecting structure 16. After the sliding piece 10 is assembled, the connecting structure 16 is operated, the positioning portion 13 is separated from the mounting portion 11, and then the positioning portion 13 covers part of the surface of the mounting portion 11.

[0037] The mounting portion 11 is used to be mounted and fixed to the second door body 310, and therefore, the mounting portion 11 is provided with a first mounting hole 111 cooperating with the first fastener 40. After mounting, in order to have better appearance, the positioning portion 13 is used to cover the first fastener 40 and the first mounting hole 111.

[0038] The two long sides of the mounting portion 11 are formed as sliding portions 12 to slide in the sliding groove 220 of the base 20. One short side of the mounting portion 11 is connected with the positioning portion 13. The surface of the mounting portion 11 is provided with a recessed groove 110 to accommodate the positioning portion 13.

[0039] The size of the recessed groove 110 is adapted to the positioning portion 13, which covers the recessed groove 110 and functions as a cover. It can be understood that the recessed groove 110 does not penetrate the sliding member 10.

[0040] The first mounting hole 111 is further provided in the recessed groove 110. It can be understood that the first mounting hole 111 is provided to penetrate the sliding member 10 to allow the first fastener 40 to pass through and be mounted, and the positioning portion 13 cooperates with the recessed groove 110 to cover the first mounting hole 111 and the first fastener 40 therein.

[0041] In a preferred embodiment, the sliding member 10 further includes a positioning structure 112 provided in the first mounting hole 111, which is used to pre-position the first fastener 40 in the first mounting hole 111. In this way, the first fastener 40 can be pre-installed in the sliding member 10, without the need to wait until the sliding member 10 is assembled with the second door body 310 before installing the first fastener 40. Moreover, the pre-positioning of the first fastener 40 in the sliding member 10 makes it less likely to be lost or confused with other fasteners of similar size and structure.

[0042] The positioning structure 112 includes a positioning rib 113 that cooperates with the screw of the first fastener 40 to be positioned. The minimum inner diameter of the positioning rib 113 is not greater than the outer diameter of the screw of the first fastener 40, and the positioning rib 113 is connected to the inner side edge of the mounting hole 112. In this way, the positioning rib 113 can clamp the screw of the first fastener 40 to achieve pre-positioning. The shape of the positioning rib 113 can be adapted to the screw to be circular, so that the inner side edge of the positioning rib 113 completely matches the outer periphery of the screw, enhancing the friction and increasing the bonding force between the two.

[0043] The positioning rib 113 and the inner side edge of the mounting hole 112 form an avoidance space to provide a space for elastic deformation of the positioning rib 113, facilitating the installation of the first fastener 40. The positioning structure 112 includes a connecting rib 114 that connects the positioning rib 113 and the inner side edge of the mounting hole.

[0044] The positioning rib 113 is used for pre-positioning the first fastener 40. When the first fastener 40 starts to be screwed into a spiral motion, if the positioning rib 113 is too hard, the operator is more difficult to operate, and the positioning rib 113 is easy to break. After the avoidance space is set, the cooperation between the positioning rib 113 and the first fastener 40 is relatively easy, which is convenient for the operator to install, and the positioning rib 113 is not easy to break, thereby prolonging the service life of the sliding part 10.

[0045] The positioning part 13 includes alignment marks used to align with the set position of the second door body 310. By aligning the alignment marks with the second door body 310, the sliding part 10 and the second door body 310 are positioned.

[0046] Specifically, the positioning part 13 includes a bottom wall 131 and side walls 132 located on both sides of the bottom wall 131 along the width direction thereof, and the bottom wall 131 is perpendicular to the side walls 132. The bottom wall 131 is a main body wall and is used to mainly cover the mounting part 11. During positioning assembly, the bottom wall 131 is in a vertical state and is parallel to the inner surface of the second door body 310, and the side walls 132 are in a horizontal state and are perpendicular to the inner surface of the second door body 310.

[0047] The alignment marks include grooves 133 arranged on both sides of the positioning part 13 along the width direction thereof, and the grooves 133 are used to align with the side edges of the second door body 310.

[0048] Each of the side walls 132 forms the groove 133, and the groove 133 includes a first inclined surface, a second inclined surface extending reversely from the first inclined surface, and an alignment line 134 located between the first inclined surface and the second inclined surface. The first inclined surface and the second inclined surface are planes, and the groove 133 has a V-shaped structure. The first inclined surface and the second inclined surface can also be arc surfaces, as long as the transition part has the alignment line 134.

[0049] As shown in FIG. 8, the alignment line 134 is a vertical straight line. When both of the alignment lines 134 are aligned with the side edges of the second door body 310, it indicates that the positioning part 13 is in the best position.

[0050] The alignment marks include a straight line part 135 arranged on the bottom wall 131, the straight line part 135 is located between the two grooves 133, and the straight line part 135 is located on the same straight line as the alignment line 134. Only the alignment line 134 is arranged, and the alignment mark is not obvious enough, and there may be errors in the observation of the human eye. The arrangement of the straight line part 135 makes the alignment mark more clear and obvious, and increases the accuracy of alignment.

[0051] The straight line part 135 can be formed as a protrusion, or a groove, or other obvious marks.

[0052] The positioning part 13 further comprises a barb part 136 provided on the side wall 132, which is used to cooperate with the buckle hole 15 of the sliding part 10. When the positioning part 13 is rotated to serve as a cover, the barb part 136 is buckled into the buckle hole 15 to prevent the positioning part 13 from falling off.

[0053] In other words, when the sliding part 10 is assembled with the positioning workpiece 30, the buckle hole 15 is used to buckle with the elastic buckle 35 of the positioning workpiece; when the first fastener 40 is screwed, the sliding part 10 is fixed to the second door body 310, the elastic buckle 35 must be detached from the buckle hole 15, so that the positioning workpiece 30 can be disassembled, and thus the buckle hole 15 is emptied, and when the positioning part 13 is rotated into the recessed groove 110, the barb part 136 is buckled into the buckle hole 15.

[0054] The base 20 comprises a vertical third mounting plate 21 used to cooperate with the positioning workpiece 30 and a fourth mounting plate 22 parallel to the sliding part 10, and the fourth mounting plate 22 is provided with a sliding groove 220 for the sliding part 10 to slide.

[0055] The base 20 comprises a second mounting hole 211 for the second fastener 50 to be installed and a limiting structure cooperating with the second fastener 50 to prevent the second fastener 50 from moving and falling off. The second mounting hole 211 and the limiting structure are provided on the third mounting plate 21. The second fastener 50 is usually pre-installed on the first door body 210, and the base 20 is installed on the first door body 210 by cooperating with the second fastener 50 through the second mounting hole 211.

[0056] The limiting structure comprises a locking hole 212 communicating with the second mounting hole 211, the inner diameter of the second mounting hole 211 is greater than the nut of the second fastener 50, and the inner diameter of the locking hole 212 is adapted to the outer diameter of the screw rod of the second fastener 50.

[0057] When fixed, the base 20 first cooperates with the gap between the nut of the second fastener 50 through the second mounting hole 211, so that the base 20 can be buckled between the second fastener 50 and the first door body 210, and then the base 20 is moved so that the screw rod of the second fastener 50 cooperates with the locking hole 212. The inner diameter of the locking hole 212 can be less than or equal to the outer diameter of the screw rod of the second fastener 50, forming an interference fit to limit the movement of the second fastener 50.

[0058] The sliding connection device 100 comprises a positioning workpiece 30, a sliding piece 10, a base 20 and the positioning workpiece 30 are separately formed. In the prior art, the positioning workpiece 30 is mainly used to assist in positioning the relative position between the sliding piece 10 and the second door body 310, so that the sliding piece 10 is fixed at the best position of the second door body 210. In the present case, the sliding piece 10 can realize positioning by itself, and the positioning workpiece 30 is only used to cooperate with the sliding piece 10 to pre-position the first fastener 40. It can be understood that after assembly is completed, the positioning workpiece 30 still needs to be further disassembled.

[0059] The positioning workpiece 30 and the sliding piece 10 are provided with a pre-positioning structure. The positioning workpiece 30 is still assembled with the sliding piece 10 to pre-position the position of the first fastener 40, which is convenient for subsequent fixation. After the positioning workpiece 30 and the sliding piece 10 are pre-positioned and assembled, the positioning part 13 of the sliding piece 10 is aligned with the second door body 310 for positioning, which is accurate, simple in structure and convenient to operate. Further, after the positioning workpiece 30 and the sliding piece 10 are pre-positioned and assembled, they are assembled together with the base 20.

[0060] The positioning workpiece 30 comprises a first mounting plate 31 cooperating with the base 20 and a second mounting plate 32 cooperating with the sliding piece 10. The first mounting plate 31 and the second mounting plate 32 are perpendicular to each other. The first mounting plate 31 cooperates with the third mounting plate 21, and the second mounting plate 32 cooperates with the mounting part 13.

[0061] The pre-positioning structure comprises a first pre-positioning part 34 provided on the second mounting plate 32 and a second pre-positioning part 14 provided on the sliding piece 10. The first pre-positioning part 34 is provided towards the sliding piece 10, and the second pre-positioning part 14 cooperates with the first pre-positioning part 34. When the positioning workpiece 30 and the sliding piece 10 are pre-positioned and assembled, the first fastener 40 should be accommodated in the accommodation groove 331.

[0062] Specifically, the first pre-positioning part 34 is a positioning column provided towards the sliding piece 10, and the second pre-positioning part 14 is a positioning hole; or the first pre-positioning part 34 is a positioning hole, and the second pre-positioning part 14 is a positioning column provided towards the positioning workpiece. The pre-positioning structure is a positioning column and a positioning hole cooperating with each other, which is simple to align and convenient to install, and also facilitates the positioning workpiece 30 to be pulled out of the sliding piece 10 when disassembled subsequently.

[0063] Specifically, after the positioning workpiece 30 and the sliding piece 10 are pre-positioned and assembled, the fixing connection between them can also be strengthened by a buckle structure. The positioning workpiece 30 is provided with an elastic buckle 35 near the first pre-positioning part 34, and the sliding piece 10 is provided with a buckle hole 15 cooperating with the elastic buckle 35. The elastic buckle 35 and the buckle hole 15 are combined to strengthen the stability of the connection between them.

[0064] The positioning workpiece 30 comprises a limiting column 33 arranged on the second mounting plate 32 and opposite to the first mounting hole 111, the limiting column 33 comprises a receiving groove 331 for receiving the first fastener 40, the first fastener 40 is limited in the receiving groove 331 and cooperates with the first mounting hole 111.

[0065] The limiting column 33 comprises a step portion 332 arranged on the end of the receiving groove 331 away from the first mounting hole 111, the step portion 332 protrudes inwardly relative to the inner wall of the receiving groove 331, the step portion 332 has a step surface 333 facing the mounting hole, the distance between the step surface 333 and the first mounting hole 111 is not greater than the length of the first fastener 40; the first fastener 40 has a pre-installation state, in the pre-installation state, the nut of the first fastener 40 is limited on the step surface 333 along the axial direction, and the end of the screw rod is limited on the positioning rib 113.

[0066] Continuing to combine FIGS. 6-8, when the positioning workpiece 30 is assembled with the sliding piece 10, the first fastener 40 is pre-installed in the receiving groove 331 and the first mounting hole 111, and when the positioning workpiece 30 and the sliding piece 10 are further assembled with the second door body 310, the first fastener 40 may be affected and deviated. In order to prevent the first fastener 40 from being affected and deviated, the step surface 333 is arranged along the axial direction of the first fastener 40, so that the nut of the first fastener 40 is limited by the step surface 333 along the axial direction, and the end of the screw rod of the first fastener 40 is also limited by the positioning rib 113 along the axial direction, and the first fastener 40 as a whole cannot deviate along the axial direction. It should be noted that the axial direction of the first fastener 40 is also the axial direction of the nut and the screw rod.

[0067] Further, the inner diameter of the receiving groove 331 gradually increases in the direction close to the first mounting hole 111, the first fastener 40 has a pre-installation state, in the pre-installation state, the nut of the first fastener 40 is limited on the inner wall of the receiving groove 331 close to the step surface 333 along the radial direction.

[0068] Specifically, the step portion 332 protrudes inwardly relative to the inner wall surface of the accommodating groove 331, the nut of the first fastener 40 is limited in the axial direction by the step surface 333, and is located below the step surface 333. If the inner diameter of the inner wall surface of the accommodating groove 331 below the step surface 333 is too large, the nut of the first fastener 40 can be tilted in the radial direction under the condition of shaking or vibration. Therefore, the inner diameter of the accommodating groove 331 near the step surface 333 is less than or equal to the outer diameter of the nut of the first fastener 40, which can hold the first fastener 40. Alternatively, the inner diameter of the accommodating groove 331 near the step surface 333 is slightly larger than the outer diameter of the nut of the first fastener 40 within 3 mm, and within this deviation range, the radial deviation of the first fastener 40 does not affect the normal installation of the first fastener 40.

[0069] The limiting column 33 includes a peripheral wall 334 surrounding the accommodating groove 331, and a through groove 335 provided on the peripheral wall 334, the through groove 335 penetrating the inner surface and the outer surface of the peripheral wall 334 in the radial direction of the limiting column 33, so that the peripheral wall 334 includes a plurality of arc-shaped walls arranged at intervals in the circumferential direction, and the peripheral wall 334 has a certain elastic deformation space to facilitate the installation of the first fastener 40.

[0070] In combination with FIGS. 6-8, the application also provides a mounting method of the sliding connection device 100, including the following mounting steps:

[0071] The base 20 is provided; the base 20 can be fixed to the first door body 210 in advance.

[0072] Specifically, the second fastener 50 is first loosened by 5-8 mm, and in other embodiments, other values can also be used according to the different sizes of the second fastener 50 or the base 20, as long as the base 20 can be clamped between the second fastener 50 and the first door body 210.

[0073] After the second fastener 50 is lifted by a distance relative to the first door body 210, the base 20 is clamped between the second fastener 50 and the first door body 210 through the second mounting hole 211, then the base 20 is moved to cooperate the locking hole 212 with the second fastener 50, and then the second fastener 50 is tightened to pre-fix the base 20 to the first door body 210.

[0074] The sliding member 10 is provided, and the sliding member 10 includes a first mounting hole 111 and a positioning structure 112 provided on the first mounting hole 111.

[0075] The first fastener 40 is provided, and the first fastener 40 is positioned on the positioning structure 112, so that the first fastener 40 is combined with the sliding member 10 in advance.

[0076] A positioning workpiece 30 is provided and assembled with a sliding member 10 pre-installed with a first fastener 40, so that the receiving groove 331 limits the first fastener 40. In this way, the first fastener 40 is limited between the sliding member 10 and the positioning workpiece 30, which facilitates subsequent fixing.

[0077] It is understood that the order in which the base 20, the slider 10, the positioning workpiece 30, and the first fastener 40 are provided is not important. It is also understood that the base 20 is independently fixed to the first door body 210. The base 20 can be pre-fixed to the first door body 210, and then the slider 10 and the positioning workpiece 30 can be assembled; alternatively, the slider 10 and the positioning workpiece 30 can be assembled first, and then the base 20 can be fixed to the first door body 210. In short, the fixing of the base to the first door body 210 is independent of the assembly of the slider 10 and the positioning workpiece 30.

[0078] The key point is that the first fastener 40 should be pre-positioned on the positioning structure 112 of the sliding member 10, and then assembled together with the positioning workpiece 30. The first pre-positioning part 34 and the second pre-positioning part 14 are positioned and engaged, the elastic buckle 35 is engaged with the buckle hole 15, and the positioning part 13 passes through the through hole 363. After the positioning workpiece 30 and the sliding member 10 are assembled, the nut of the first fastener 40 is limited to the receiving groove 331, and the end of the screw of the first fastener 40 is limited to the positioning structure 112.

[0079] Next, the sliding member 10 and the positioning workpiece 30 are then fitted together with the base 20 on the first door body 210. Specifically, the first door body 210 and the second door body 310 should be opened to approximately the same angle. The assembled sliding member 10 and the positioning workpiece 30 fit into the base 20 along the length of the first door body 210, wherein the sliding part 12 of the sliding member 10 slides into the sliding groove 220 of the base 20. After sliding a certain distance, the first mounting plate 31 of the positioning workpiece 30 gradually comes into contact with the third mounting plate 21 of the base 20. At this time, referring to the alignment mark of the positioning part 13, when the alignment line 134 and the straight part 135 are aligned and coincide with the side edge of the second door body 310, it indicates that the positioning workpiece 30 has been installed in place.

[0080] Furthermore, a first fastener 40 is pre-installed in the positioning workpiece 30 and the sliding member 10. The first fastener 40 is tightened with a screwdriver and fixed to the second door body 310 along the axial direction of the receiving groove 331. The mounting rib 113 of the receiving groove 331 can play a limiting role. When the head of the first fastener 40 reaches the bottom surface of the recessed groove 110, the first fastener 40 is installed in place. In this way, the sliding member 10 is fixed to the second door body 310.
