[0037] Reference Figure 1 , an embodiment of the utility model provides a sliding connection device 100, referring to Figure 5 In one embodiment of the utility model, a household appliance device 1000 is provided. The household appliance device 1000 includes a built-in household appliance 200, such as a refrigerator, and a cabinet 300 for accommodating the built-in household appliance 200. The household appliance 200 includes a first door body 210 and a box body, and the first door body 210 is used to open or close the box body.

[0038] The cabinet 300 includes a second door body 310, which covers the first door body 210. The sliding connection device 100 is used to slidingly connect the first door body 210 to the second door body 310. When the second door body 310 is opened, the first door body 210 can be driven to open, thereby opening the box of the household appliance 200.

[0039] In a preferred embodiment, combined with Figure 2-4 As shown, the sliding connection device 100 includes a sliding connection component and a positioning workpiece 30 for positioning the relative position between the sliding connection component and the second door body 310. The positioning workpiece 30 is used to assist in positioning the sliding connection component so that it is fixed at the optimal position of the second door body 210. Usually, after the positioning is completed, the positioning workpiece 30 needs to be removed relative to the sliding member 10.

[0040] In one embodiment, the sliding connection assembly includes a sliding member 10 and a base 20 that are slidably connected, and a positioning workpiece 30. The sliding member 10 and the base 20 are arranged between the first door body 210 and the second door body 310 to drive the first door body 210 and the second door body 310 to be slidably connected. The sliding member 10, the base 20, and the positioning workpiece 30 are formed separately.

[0041] In other embodiments, combined Fig.13 As shown, the base 20 and the positioning workpiece 30 can be integrally formed and connected by a detachable portion. When positioning is completed, the positioning workpiece 30 and the base 20 are separated from the base 20 by operating the detachable portion and removed from the sliding member 10. It can be understood that the other structures of the base 20 and the positioning workpiece 30 remain consistent.

[0042] In one embodiment, the sliding connection device 100 further includes a first fastener 40 for fixing the sliding member 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 member 10 is relatively fixed to the second door body 310, the base 20 is relatively fixed to the first door body 210, and the sliding member 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.

[0043] In a specific embodiment, the first fastener 40 and the second fastener 50 are both screws, and the first fastener 40 and the second fastener 50 both include a nut and a screw. In a specific embodiment, the size and detailed structure of the first fastener 40 and the second fastener 50 may be different, as long as the function of fixed connection can be achieved by the screw.

[0044] The sliding member 10 is a sheet-shaped body, and the sliding member 10 includes a mounting portion 11 and a cover portion 13. The mounting portion 11 is used to be installed and fixed to the second door body 310. Therefore, the mounting portion 11 is provided with a first mounting hole 111 that cooperates with the first fastener 40. After the installation is completed, in order to have a better appearance, the cover portion 13 is used to cover the first fastener 40 and the first mounting hole 111.

[0045] In a specific embodiment, there is a connecting structure between the cover body 13 and the mounting portion 11, and the connecting mechanism is configured as follows: the cover body 13 can rotate around the connecting structure to cover a portion of the surface of the mounting portion 11, and the connecting structure will not be broken; in other words, the thickness of the connecting structure gives it a certain connection rigidity, but it can also be elastically deformed to allow the cover body 13 to cover the mounting portion 11.

[0046] In other embodiments, the cover body portion 13 and the mounting portion 11 can be connected by a rotating shaft, so that the cover body portion 13 can be rotated to the surface of the mounting portion 11; or, the cover body portion 13 and the mounting portion 11 are connected by a detachable structure. When the sliding member 10 is assembled, the detachable structure is operated to separate the cover body portion 13 from the mounting portion 11, and then the cover body portion 13 covers a portion of the surface of the mounting portion 11. Specifically, the detachable structure can be a thin, easily breakable structure, or a detachable snap-on structure.

[0047] The two long sides of the mounting portion 11 are formed as sliding portions 12 for sliding in the sliding groove 220 of the base 20. The cover portion 13 is connected to one short side of the mounting portion 11. A recessed groove 110 for accommodating the cover portion 13 is provided on the surface of the mounting portion 11. It is understood that the recessed groove 110 does not penetrate the sliding member 10.

[0048] The first mounting hole 111 is further arranged in the recessed groove 110. It can be understood that the first mounting hole 111 is arranged to penetrate the sliding member 10 so that the first fastener 40 can pass through for installation, and after the cover body 13 cooperates with the recessed groove 110, it just covers the first mounting hole 111 and the first fastener 40 therein.

[0049] In a preferred embodiment, the sliding member 10 further includes a positioning structure 112 disposed in the first mounting hole 111, and the positioning structure 112 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 on the sliding member 10, and there is no need to wait until the sliding member 10 and the second door body 310 are assembled before installing the first fastener 40. In addition, the first fastener 40 is pre-positioned on the sliding member 10, so it is not easy to be lost, and it will not be confused with other fasteners of similar size and similar structure.

[0050] In a preferred embodiment, the positioning structure 112 includes a positioning rib 113 that is positioned and matched with the screw of the first fastener 40. The minimum inner diameter of the positioning rib 113 is not greater than the outer diameter of the screw of the first fastener 40. The positioning rib 113 is connected to the inner edge of the mounting hole 112. In this way, the positioning rib 113 can clamp the screw of the first fastener 40, thereby achieving pre-positioning. The shape of the positioning rib 113 can be adapted to the screw to form a circle, so that the inner edge of the positioning rib 113 completely matches the outer periphery of the screw, thereby enhancing the friction force and increasing the strength of the combination of the two.

[0051] In a preferred embodiment, an escape space is formed between the positioning rib 113 and the inner edge of the mounting hole 112 to provide space for elastic deformation of the positioning rib 113 to facilitate the installation of the first fastener 40. The positioning structure 112 includes a connecting rib 114 connecting the positioning rib 113 and the inner edge of the mounting hole.

[0052] The positioning rib 113 is used to pre-position the first fastener 40. When the first fastener 40 begins to be tightened and performs a spiral motion, if the positioning rib 113 is too hard, it will be difficult for the operator to operate it, and the positioning rib 113 is easy to break. After the avoidance space is set, the positioning rib 113 and the first fastener 40 are relatively easy to cooperate with, which is convenient for the operator to install, and the positioning rib 113 is not easy to break, thereby improving the service life of the sliding part 10.

[0053] In one embodiment, the base 20 includes a vertical third mounting plate 21 and a fourth mounting plate 22, the third mounting plate 21 cooperates with the first mounting plate 31 for positioning the workpiece 30, the fourth mounting plate 22 is parallel to the sliding member 10, and the fourth mounting plate 22 is provided with a sliding groove 220 for the sliding member 10 to slide.

[0054] The base 20 includes a second mounting hole 211 for mounting the second fastener 50 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 arranged on the third mounting plate 21. The second fastener 50 is usually pre-installed on the first door body 210, and the base 20 cooperates with the second fastener 50 through the second mounting hole 211, so as to be installed on the first door body 210.

[0055] The limiting structure includes a locking hole 212 connected to the second mounting hole 211 . The inner diameter of the second mounting hole 211 is larger than the nut of the second fastener 50 . The inner diameter of the locking hole 212 is adapted to the outer diameter of the screw of the second fastener 50 .

[0056] When fixing, the base 20 first cooperates with the nut clearance of the second fastener 50 through the second mounting hole 211, so that the base 20 can be inserted between the second fastener 50 and the first door body 210, and then the base 20 is moved so that the screw 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 of the second fastener 50, forming an interference fit to limit the movement of the second fastener 50.

[0057] In a preferred embodiment, the positioning workpiece 30 is used to position the sliding member 10 on the second door body 310. After the positioning workpiece 30 is assembled with the sliding member 10, the positioning workpiece 30 is aligned with the second door body 310 to achieve alignment of the sliding member 10 with the second door body 310, and then the sliding member 10 is fixed on the second door body 310.

[0058] In a preferred embodiment, a pre-positioning structure is provided between the positioning workpiece 30 and the sliding connection assembly, and the positioning workpiece 30 includes an alignment portion 36 for aligning and positioning with a set position on the second door body 310. In this way. After the positioning workpiece 30 is pre-positioned and assembled with the sliding connection assembly, it is then positioned with the second door body 310 by alignment, and the positioning is accurate, the structure is simple, and the operation is convenient. Specifically, the positioning workpiece 30 is pre-positioned and assembled with the sliding member 10, and then assembled with the base 20 together.

[0059] As described above, the main function of the positioning workpiece 30 is to assist the sliding member 10 in positioning on the second door body 310 , and the alignment portion 36 is used to achieve alignment between the positioning workpiece 30 and the second door body 310 , thereby indirectly achieving alignment between the sliding member 10 and the second door body 310 .

[0060] In one embodiment, the alignment portion 36 has an alignment surface 361 for aligning with the side surface of the second door body 310. Figure 6-8 As shown, the alignment surface 361 is planar. When the alignment surface 361 is aligned with the side surface of the second door body 310 and is located in the same plane, the alignment can be directly observed, measured by hand, or measured with a ruler or other tools, proving that the positioning workpiece 30 has been installed in place and the first fastener 40 can be further operated.

[0061] The alignment portion 36 has an abutting surface 362 for abutting against the inner surface of the second door body 310, and the alignment surface 361 is perpendicular to the abutting surface 362. The alignment portion 36 is a square plate, and the alignment surface 361 and the abutting surface 362 are adjacent outer surfaces. In this way, the abutting surface 362 abuts against the inner surface of the second door body 310, and the alignment surface 361 is aligned with the side surface of the second door body 310, which is more conducive to the accurate positioning between the positioning workpiece 30 and the second door body 310.

[0062] In one embodiment, the positioning workpiece 30 includes two alignment portions 36 spaced apart and arranged on the same side of the positioning workpiece 30 . A through hole 363 is formed between the two alignment portions 36 , and the sliding member 10 passes through the through hole 363 .

[0063] Combination Figure 2 , 6 As shown, the sliding member 10 includes a cover body portion 13 connected to a short side of the mounting portion 11. The sliding member 10 is initially longer. When cooperating with the positioning workpiece 30, the through opening 363 can also avoid the cover body portion 13, and the two alignment portions 36 are located on both sides of the cover body portion 13 along its width direction to facilitate the above-mentioned abutment surface 362 to abut against the inner surface of the second door body 310.

[0064] Combination Fig.14 As shown, the abutting surfaces 362 of the two alignment portions 36 may also extend to be connected together to form a plane that abuts against the inner surface of the second door body 310 .

[0065] The positioning workpiece 30 includes a first mounting plate 31 that cooperates with the base 20 and a second mounting plate 32 that cooperates with the sliding member 10. The first mounting plate 31 and the second mounting plate 32 are perpendicular to each other. The first mounting plate 31 is perpendicular to the second mounting plate 32. The alignment portion 36 is arranged on the second mounting plate 32 and extends vertically from the second mounting plate 32. The alignment portion 36 and the first mounting plate 31 are located on opposite sides of the second mounting plate 32.

[0066] Specifically, the “opposite sides” refer to: one side facing the first door body 210 and the other side facing the second door body 310. The alignment portion 36 is vertically arranged from the edge of the second mounting plate 32 toward the second door body 310 to achieve alignment with the second door body 310; the first mounting plate 31 is vertically arranged from the edge of the second mounting plate 32 toward the first door body 210 to achieve fixed connection with the first door body 210.

[0067] In one embodiment, the pre-positioning structure includes a first pre-positioning portion 34 disposed on the second mounting plate 32 and a second pre-positioning portion 14 disposed on the sliding member 10. The first pre-positioning portion 34 is disposed toward the sliding member 10, and the second pre-positioning portion 14 is positioned and matched with the first pre-positioning portion 34. When the positioning workpiece 30 and the sliding member 10 are pre-positioned and assembled, the first fastener 40 should be received in the receiving groove 331.

[0068] In a specific embodiment, the first pre-positioning portion 34 is a positioning column arranged toward the sliding member 10, and the second pre-positioning portion 14 is a positioning hole; or the first pre-positioning portion 34 is a positioning hole, and the second pre-positioning portion 14 is a positioning column arranged toward the positioning workpiece. The pre-positioning structure is provided as a positioning column and a positioning hole that cooperate with each other, which is simple to align and easy to install, and also convenient to pull out the positioning workpiece 30 from the sliding member 10 during subsequent disassembly.

[0069] Specifically, after the positioning workpiece 30 and the sliding member 10 are pre-positioned and assembled, the fixed connection between the two can be strengthened by a snap-on structure. The positioning workpiece 30 is provided with an elastic snap 35 near the first pre-positioning portion 34, and the sliding member 10 is provided with a snap hole 15 that cooperates with the elastic snap 35. The elastic snap 35 is combined with the snap hole 15 to strengthen the stability of the connection between the two.

[0070] The positioning workpiece 30 includes a limiting column 33 disposed on the second mounting plate 32 and opposite to the first mounting hole 111 . The limiting column 33 includes 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 .

[0071] The limiting column 33 includes a step portion 332 arranged at one end of the receiving groove 331 away from the first mounting hole 111, and the step portion 332 protrudes inward relative to the inner wall surface of the receiving groove 331. The step portion 332 has a step surface 333 facing the mounting hole, and 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-installed state, in which the nut of the first fastener 40 is limited to the step surface 333 along its axial direction, and the end of the screw is limited to the positioning rib 113.

[0072] Continue to combine Figure 6 , 9 As shown, when the positioning workpiece 30 and the sliding member 10 are assembled, the first fastener 40 is pre-installed in the receiving groove 331 and the first mounting hole 111. When the positioning workpiece 30 and the sliding member 10 are further assembled with the second door body 310, shaking may occur. In order to prevent the first fastener 40 from being affected and offset, a step surface 333 is set along the axial direction of the first fastener 40. In this way, the nut of the first fastener 40 is restricted by the step surface 333 along the axial direction, and the end of the screw of the first fastener 40 is also restricted by the positioning rib 113 along the axial direction, and the first fastener 40 as a whole cannot be offset along the axial direction. It should be noted that the axial direction of the first fastener 40 is also the common axial direction of its nut and screw.

[0073] Furthermore, the inner diameter of the receiving groove 331 gradually increases in the direction approaching the first mounting hole 111, and the first fastener 40 has a pre-installed state. In the pre-installed state, the nut of the first fastener 40 is radially limited to the inner wall surface of the receiving groove 331 adjacent to the step surface 333.

[0074] Specifically, the step portion 332 protrudes inward relative to the inner wall surface of the receiving groove 331, and the nut of the first fastener 40 is limited to the step surface 333 along the axial direction and is located below the step surface 333. If the inner diameter of the inner wall surface of the receiving groove 331 below the step surface 333 is too large, the nut of the first fastener 40 may be tilted in the radial direction in the case of shaking or vibration. Therefore, the inner diameter of the receiving groove 331 near the step surface 333 is set to be less than or equal to the outer diameter of the nut of the first fastener 40, so that the first fastener 40 can be clamped. Alternatively, the inner diameter of the receiving 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. Within this deviation range, the radial deviation of the first fastener 40 will not affect the normal installation of the first fastener 40.

[0075] In one embodiment, the limiting column 33 includes an outer peripheral wall 334 that surrounds the receiving groove 331 and a through groove 335 arranged on the outer peripheral wall 334. The through groove 335 penetrates the inner surface and the outer surface of the outer peripheral wall 334 along the radial direction of the limiting column 33, so that the outer peripheral wall 334 includes a plurality of arc walls arranged at intervals along the circumferential direction. The outer peripheral wall 334 has a certain elastic deformation space, which is convenient for the installation of the first fastener 40.

[0076] Combination Figure 10-12 As shown, the present application also provides an installation method of a sliding connection device 100, comprising the following installation steps:

[0077] The base 20 is provided; the base 20 may be fixed to the first door body 210 in advance.

[0078] Specifically, the second fastener 50 is pre-loosened by 5-8 mm. In other embodiments, other values ​​may be used according to different sizes of the second fastener 50 or the base 20 , as long as the base 20 can be inserted between the second fastener 50 and the first door body 210 .

[0079] After lifting the second fastener 50 a certain distance relative to the first door body 210, the base 20 is inserted between the second fastener 50 and the first door body 210 through the second mounting hole 211, and then the base 20 is moved, the locking hole 212 is matched 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.

[0080] The sliding member 10 is provided. The sliding member 10 includes a first mounting hole 111 and a positioning structure 112 disposed in the first mounting hole 111 .

[0081] A first fastener 40 is provided, and the first fastener 40 is pre-positioned at the positioning structure 112 , so that the first fastener 40 is pre-combined with the sliding member 10 .

[0082] 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 is convenient for subsequent fixation.

[0083] It is understandable that the base 20, the sliding member 10, the positioning workpiece 30 and the first fastener 40 are provided in any order. It is understandable that the base 20 is independently fixed to the first door body 210. The base 20 can be fixed to the first door body 210 in advance, and then the sliding member 10 and the positioning workpiece 30 are assembled; or, after the sliding member 10 and the positioning workpiece 30 are assembled, the base 20 is fixed to the first door body 210; in short, the base is fixed to the first door body 210, and is independent of the assembly of the sliding member 10 and the positioning workpiece 30.

[0084] The key point is that the first fastener 40 should be pre-positioned in the positioning structure 112 of the sliding member 10, and then assembled with the positioning workpiece 30. The first pre-positioning portion 34 is positioned and matched with the second pre-positioning portion 14, the elastic buckle 35 is buckled with the buckle hole 15, and the cover body 13 passes through the through opening 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.

[0085] Next, the sliding member 10 and the positioning workpiece 30 are matched with the base 20 on the first door body 210. Figure 10-12 , the first door body 210 and the second door body 310 should be opened to basically the same angle. The assembled sliding member 10 and the positioning workpiece 30 cooperate with the base 20 along the length direction of the first door body 210, wherein the sliding portion 12 of the sliding member 10 slides into the sliding groove 220 of the base 20. After sliding for a certain distance, the first mounting plate 31 of the positioning workpiece 30 gradually abuts against the third mounting plate 21 of the base 20. At this time, referring to the alignment portion 36, when the alignment surface 361 is aligned with the side surface of the second door body 310 and is located in the same plane, it means that the positioning workpiece 30 has been installed in place, and the first mounting plate 31 and the third mounting plate 21 can also be snap-fastened to further position the positioning workpiece 30.

[0086] Furthermore, the 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. The first fastener 40 is 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 contacts 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 with the help of the positioning workpiece 30.

[0087] Finally, the positioning workpiece 30 is to be disassembled from the base 20 and the sliding member 10. The snap connection between the first mounting plate 31 and the third mounting plate 21 is released, the snap connection between the second mounting plate 32 and the sliding member 10 is released, and the first pre-positioning portion 34 and the second pre-positioning portion 14 are pulled out and separated. In this way, the positioning workpiece 30 can be removed relative to the base 20 and the sliding member 10.

[0088] Taking into account the aesthetic effect, the cover body 13 of the sliding member 10 is rotated and covered to the recessed groove 110, so as to cover the first fastener 40 and the first mounting hole 111 therein; the sliding connection device 100 also includes a base cover 23, and the base cover 23 and the base 20 can be formed integrally, and the base cover 23 and the base 20 are further separated during assembly to prevent the base cover 23 from being lost, and then the base cover 23 is assembled to the outer periphery of the base 20 to cover the entire base 20, thereby playing a role of aesthetic decoration; the base cover 33 and the base 20 can also be formed independently of each other.

[0089] The cover body 13 and the base cover 23 are both provided with notches for convenient operation by staff, so as to meet the need of opening the cover body 13 or the base cover 23 later.

[0090] An embodiment of the present application further provides a door assembly, which includes the first door body 210 , the second door body 310 and the sliding connection device 100 , and the sliding member 10 and the base 20 slidingly connect the first door body 210 and the second door body 310 .

[0091] The beneficial effects of the utility model are: a positioning portion 36 is provided to achieve positioning with the second door body 310 by alignment, the structure is simple, and the operation is convenient; a pre-positioning structure and a snap-fit ​​structure are provided between the sliding member 10 and the positioning workpiece 30, and after the two are pre-positioned and assembled, the positioning workpiece 30 is further aligned and positioned with the second door body 310 to improve the accuracy of positioning.
