[0037] Referring to Figures 1 to 11, this embodiment of the present disclosure provides a refrigerator 500, which includes a cabinet and a shelf placed in the cabinet. The shelf includes a shelf body 400, a slide rail assembly, a movable pulley assembly 420, a fixing assembly 310, a winding wheel assembly 410, and a drive assembly. As shown in Figure 1, the shelf body 400 is connected to the movable pulley assembly 420, and the movable pulley assembly 420 is connected to the slide rail body 300 of the slide rail assembly. The fixing assembly 310 is disposed on the slide rail body 300 and is used to fix the first end of the pull rope 330, and the second end of the pull rope 330 is connected to the winding wheel assembly 410. The drive assembly is used to drive the winding wheel assembly 410 to rotate, and when the winding wheel assembly 410 rotates, it winds or releases the pull rope 330. The movable pulley assembly 420 is mounted on the pull rope 330. When the drive assembly drives the drive winding wheel assembly 410 to rotate, the length of the pull rope 330 changes, which in turn causes the movable pulley assembly 420 to move along the pull rope 330. Thus, the movable pulley assembly 420 drives the shelf body 400 to move along the slide rail body 300.

[0038] In the first embodiment, the drive assembly includes a drive gear 100, a micro switch, and a controller. The drive gear 100 has a groove 111 on its web 110, which forms a first trajectory as the drive gear 100 rotates. The micro switch includes a moving part 120, a spring part 130, and a trigger part 140. As shown in FIG2, the moving part 120 is located on one side of the groove 111. The spring part 130 provides elastic force to the moving part 120 so that the moving part 120 is always located on the first trajectory. When the moving part 120 moves under the elastic force, it forms a second trajectory, and the trigger part 140 is located on the second trajectory. When the moving part 120 enters the groove 111, it contacts the trigger part 140, triggering the trigger part 140. The controller is configured to control the rotation state of the drive gear 100 according to the trigger signal from the trigger part 140.

[0039] In this embodiment, when the drive gear 100 rotates, it drives the groove 111 to rotate synchronously, and the groove 111 forms a first trajectory as it rotates. Under the action of the spring part 130, the moving part 120 is always located on the first trajectory. When the groove 111 rotates to the position corresponding to the moving part 120, the moving part 120 enters the groove 111, and the moving part 120 forms a second trajectory as it moves. At this time, the moving part 120 contacts the trigger part 140, causing the trigger part 140 to be triggered. Furthermore, after receiving the trigger signal, the controller controls the rotation state of the drive gear 100, such as stopping or reversing. In this way, through ingenious structural design, an accurate triggering and response mechanism is formed, which facilitates efficient control of the rotation state of the drive component.

[0040] Optionally, as shown in FIG2, the moving part 120 includes a protrusion 121 and a cantilever 122. The protrusion 121 corresponds to the groove 111; the cantilever 122 is connected to the protrusion 121 and corresponds to the trigger part 140. Thus, the protrusion 121 can be inserted into the groove 111, and after being inserted, the cantilever 122 contacts the trigger part 140, thereby triggering the trigger part 140.

[0041] Optionally, as shown in Figure 4, the drive assembly further includes a limiting groove 150, which is disposed on one side of the groove 111 and extends along the second trajectory; the groove wall of the limiting groove 150 is provided with a through opening 151 along its extending direction; wherein, the protrusion 121 is disposed in the limiting groove 150 and can move along the limiting groove 150; the cantilever 122 extends out of the limiting groove 150 through the through opening 151 and can move along the through opening 151.

[0042] In this embodiment, the limiting groove 150 serves to limit the movement trajectory of the protrusion 121, which is beneficial for the protrusion 121 to accurately sink into the groove 111. The through opening 151 serves to guide the cantilever 122, which is beneficial for the cantilever 122 to accurately contact the trigger part 140.

[0043] For example, the limiting groove 150 is formed by four plate segments on the back plate 201 of the motor housing 200, and the whole is rectangular to match the protrusion 121.

[0044] Optionally, as shown in Figure 2, the spring portion 130 is disposed within the limiting groove 150, with its first end connected to the limiting groove 150 and its second end connected to the protrusion 121. In this way, the limiting groove 150 serves to accommodate the spring portion 130, ensuring that the elastic force of the spring portion 130 can stably act on the protrusion 121.

[0045] For example, when other positions on the web 110 of the drive gear 100 contact the protrusion 121, the spring portion 130 is in an elastic energy storage state. When the drive gear 100 rotates to the point where the groove 111 corresponds to the protrusion 121, the spring portion 130 releases its elastic force, pushing the protrusion 121 into the groove 111.

[0046] Optionally, the protrusion 121 is provided with a receiving groove 123, and the second end of the spring portion 130 is connected to the receiving groove 123. In this way, the receiving groove 123 helps to improve the connection stability between the spring portion 130 and the protrusion 121.

[0047] As exemplarily shown in Figures 3A and 3B, the receiving groove 123 is constructed as a cylinder, and the diameter of the receiving groove 123 is adapted to the diameter of the spring.

[0048] Optionally, as shown in Figures 33A and 3B, the groove 111 is provided with ramps 112 on both sides to facilitate the movement of the moving part 120 in and out of the groove 111. In this way, the ramps 112 ensure that the moving part 120 can smoothly enter or leave the groove 111, reducing jamming.

[0049] Optionally, as shown in FIG4, the drive assembly further includes a mounting plate 141. The mounting plate 141 is disposed on one side of the micro switch and is used to mount the trigger part 140. In this way, the mounting plate 141 provides a mounting position for the trigger part 140.

[0050] For example, the fixing plate 141 is disposed on the back plate 201 of the motor housing 200.

[0051] Optionally, the shelf includes the aforementioned drive assembly.

[0052] Optionally, as shown in Figure 1, the shelf also includes a shelf body 400, a winding wheel assembly 410, and a pull rope assembly. The shelf body 400 is movable along the slide rail assembly; the drive gear 100 drives the winding wheel assembly 410 to rotate; the winding wheel assembly 410 drives the shelf body 400 to move via the pull rope assembly; and when the controller receives a trigger signal, it controls the drive gear 100 to stop or reverse rotation, thereby controlling the shelf body 400 to stop moving or move in the opposite direction.

[0053] For example, the slide rail body 300 of the slide rail assembly is arranged vertically, and the shelf body 400 can rise or fall along the slide rail body 300. When the drive gear 100 rotates clockwise, the winding wheel assembly 410 winds the pull rope 330, at which time the pull rope 330 shortens and pulls the shelf body 400 upward. When the drive gear 100 rotates to the trigger position, the moving part 120 enters the groove 111, at which time the trigger part 140 is triggered. When the controller receives the trigger signal, it controls the drive gear 100 to stop rotating, at which point the shelf body 400 rises to the limit position and no longer rises. Alternatively, when the controller receives the trigger signal, it controls the drive gear 100 to reverse a certain stroke, so that the shelf body 400 does not stop at the limit position and falls a certain distance. In this way, the shelf body 400 can be prevented from moving excessively upward.

[0054] In another example, when the drive gear 100 rotates counterclockwise, the winding wheel assembly 410 releases the pull rope 330, at which point the pull rope 330 lengthens and the shelf body 400 descends. When the drive gear 100 rotates to the trigger position, the moving part 120 engages the groove 111, at which point the trigger part 140 is activated. Upon receiving the trigger signal, the controller stops the drive gear 100, at which point the shelf body 400 descends to its limit position and stops descending further. This prevents the shelf body 400 from moving excessively downwards.

[0055] Optionally, the refrigerator 500 includes a cabinet, and the aforementioned shelves are placed within the cabinet. This allows the user to adjust the position of the shelves via a drive assembly as needed, facilitating the storage and retrieval of items within the refrigerator 500.

[0056] In the second embodiment, the drive assembly includes a motor housing 200, a mounting plate 220, and a shock-absorbing pad 230. As shown in FIG5, the motor housing 200 includes a back plate 201, and a first side of the back plate 201 is provided with a claw portion 210 and a positioning portion 213; the mounting plate 220 is located on the first side of the back plate 201 and is provided with a slot 221 and an insertion hole 222; wherein, the slot 221 corresponds to the claw portion 210, and the insertion hole 222 corresponds to the positioning portion 213; the shock-absorbing pad 230 is located between the back plate 201 and the mounting plate 220 and is provided with a first clearance opening 231 and a second clearance opening 232; and the claw portion 210 passes through the first clearance opening 231 and engages in the slot 221, and the positioning portion 213 passes through the second clearance opening 232 and is inserted into the insertion hole 222.

[0057] In this embodiment, when installing the drive assembly, the claw part 210 is first passed through the first clearance opening 231, and the positioning part 213 is passed through the second clearance opening 232, that is, the shock-absorbing pad 230 is assembled onto the back plate 201. Then, the positioning part 213 is inserted into the insertion hole 222, and the claw part 210 is engaged in the slot 221. At this time, the back plate 201 is fixed to the mounting plate 220, and the shock-absorbing pad 230 is located between the two. In this way, the positioning and initial fixation between the motor housing 200 and the mounting plate 220 are completed, so that the motor housing 200 can be further fixed to the mounting plate 220 with screws and fasteners without manual support, which effectively improves the installation efficiency.

[0058] Optionally, the back plate 201 and the front cover 202 together enclose the motor housing 200, and the winding wheel assembly 410 is located on the side of the front cover 202 away from the back plate 201.

[0059] Optionally, as shown in Figure 6, the claw portion 210 includes a first claw segment 211 and a second claw segment 212. The first end of the first claw segment 211 is connected to the back plate 201, and its second end extends toward the mounting plate 220. The first end of the second claw segment 212 is connected to the second end of the first claw segment 211, and its second end extends perpendicular to the first claw segment 211. Thus, through the connection design of the first claw segment 211 and the second claw segment 212, the entire claw portion 210 forms a stable clamping structure.

[0060] Optionally, the second end of the second claw segment 212 is constructed as a pointed shape. In this way, the pointed design allows the second claw segment 212 to pass through the first clearance opening 231 more smoothly and to be more easily engaged in the slot 221.

[0061] Optionally, as shown in Figure 7, two claw portions 210 are respectively disposed on the upper sides of the back plate 201, and the second end of the second claw segment 212 extends upward. In this way, the layout of the claw portions 210 and the extension direction of the second claw segment 212 conform to the user's installation habits and help improve installation efficiency.

[0062] Optionally, as shown in FIG6, the positioning part 213 includes a positioning post. The first end of the positioning post is connected to the back plate 201, and the second end extends toward the mounting plate 220. Here, the positioning post is cylindrical, which facilitates smooth passage through the second clearance opening 232 and allows for more accurate insertion into the insertion hole 222.

[0063] Optionally, the back plate 201 has screw holes around its periphery, through which screws can be used to fix the back plate 201 to the mounting plate 220.

[0064] In this embodiment, after the positioning and initial fixing between the motor housing 200 and the mounting plate 220 are completed using the claw part 210 and the positioning part 213, screw fasteners are further used to fix the motor housing 200 onto the mounting plate 220 through the screw holes. In this way, the motor housing 200 is finally fixed onto the mounting plate 220.

[0065] Optionally, as shown in Figure 1, the shelf also includes a shelf body 400, a winding wheel assembly 410, and a pull rope assembly. The shelf body 400 is movable along the slide rail assembly; the drive assembly drives the winding wheel assembly 410 to rotate; the winding wheel assembly 410 drives the shelf body 400 to move via the pull rope assembly. Thus, the drive assembly can move the shelf body 400.

[0066] Optionally, the refrigerator 500 includes a cabinet, with the aforementioned shelves housed within the cabinet. This allows the user to adjust the position of the shelves via a drive assembly as needed, facilitating the storage and retrieval of items within the refrigerator 500.

[0067] Optionally, the mounting plate 220 is pre-embedded in the inner liner of the refrigerator 500. In this way, the mounting plate 220 can be regarded as part of the inner liner, which facilitates the installation of the drive assembly on the inner liner and helps to make full use of the internal space of the refrigerator 500.

[0068] In the third embodiment, the shelf includes a slide rail assembly and a fixing assembly 310. As shown in FIG8, the slide rail assembly includes a slide rail body 300, and the slide rail body 300 is provided with a guide groove 301; the fixing assembly 310 is used to fix the pull rope 330, and includes an insert 311 and a limiting port 313; wherein, the insert 311 is inserted into the guide groove 301, and the guide groove 301 and the insert 311 are fixed by a fixing screw 312; the limiting port 313 is located on one side of the insert 311 and is offset from the fixing screw 312; and the pull rope 330 extends through the limiting port 313 and is connected to the fixing assembly 310 to prevent the pull rope 330 from getting tangled in the fixing screw 312.

[0069] In this embodiment, the fixing component 310 is inserted into the guide groove 301 via the insert block 311, and then a fixing screw 312 is used to pass through the groove wall of the guide groove 301 from the outside and fix it to the insert block 311, so that the screw head of the fixing screw 312 is located outside the guide groove 301. At this time, when the pull rope 330 is slack or shakes, there is a risk of the screw head getting tangled, as shown by the dotted line in Figure 9. However, in this application, after the pull rope 330 extends through the limiting port 313, the limiting port 313 effectively limits the shaking range of the pull rope 330. Since the limiting port 313 and the fixing screw 312 are staggered, if the pull rope 330 becomes slack or shakes, the limiting port 313 can prevent the pull rope 330 from getting tangled in the screw head.

[0070] Optionally, as shown in Figure 10, when the pull rope 330 is in the tensioned state, the distance between the pull rope 330 and the inner wall of the limiting port 313 is d, and d≥2mm. This ensures that there is sufficient clearance between the pull rope 330 and the inner wall of the limiting port 313, which can prevent excessive friction between the pull rope 330 and the inner wall of the limiting port 313 during shaking, and helps to extend the service life of the pull rope 330.

[0071] For example, the distance d between the pull cord 330 and the inner wall of the limiting port 313 can be selected as 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm or 6mm.

[0072] Optionally, when the pull rope 330 is in the tensioned state, the pull rope 330 inside the limiting opening 313 is located at the center of the limiting opening 313. This makes the distance between the pull rope 330 and the inner wall of the limiting opening 313 relatively uniform, reducing the risk of damage caused by local wear.

[0073] Optionally, the limiting port 313 is configured as a circular port, an elliptical port, a square port, or a strip-shaped port.

[0074] Optionally, a notch 320 is provided on the side of the limiting port 313, through which the pull rope 330 can be assembled into the limiting port 313. In this way, since the pull rope 330 is relatively long and its layout is relatively complex, the assembly difficulty of the pull rope 330 can be reduced by the notch 320 design.

[0075] Optionally, as shown in Figure 10, the side of the limiting port 313 is divided into a first edge 321 and a second edge 322 by a notch 320. The first edge 321 and the second edge 322 are arranged close together, and the pull rope 330 can be squeezed into the limiting port 313 from the notch 320.

[0076] In this embodiment, both the first edge 321 and the second edge 322 have a certain deformation and recovery capability. When the pull rope 330 squeezes the two edges, it deforms, causing the notch 320 to open, and then the pull rope 330 enters the limiting opening 313. After entering, the two edges recover to the abutting position, causing the notch 320 to close, thus preventing the pull rope 330 from leaving the limiting opening 313 from the notch 320.

[0077] Optionally, the contact surfaces of the first edge 321 and the second edge 322 are inclined at an angle of α, where 0 < α ≤ 80°. This reasonable design of the inclination angle facilitates the smoother insertion of the pull rope 330 into the limiting port 313.

[0078] For example, the tilt angle α can be selected as 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or 80°.

[0079] Optionally, as shown in Figure 1, the shelf also includes a shelf body 400 and a winding wheel assembly 410. The shelf body 400 is movable along the guide groove 301; the winding wheel assembly 410 drives the shelf body 400 to move via a pull rope 330. Here, the shelf body 400 is connected to a movable pulley assembly 420, which is mounted on the pull rope 330. When the winding wheel assembly 410 winds or releases the pull rope 330, the movable pulley assembly 420 moves along the pull rope 330, thereby driving the shelf body 400 to move along the guide groove 301.

[0080] Optionally, the refrigerator 500 includes a cabinet, with the aforementioned shelves housed within the cabinet. This allows the user to adjust the position of the shelves via a drive assembly as needed, facilitating the storage and retrieval of items within the refrigerator 500.

[0081] The shelves and refrigerators provided in this disclosure can achieve the following technical effects:

[0082] The fixing component is inserted into the guide groove via a plug, and then a fixing screw is used to fix it to the plug from the outside through the groove wall, so that the screw head is outside the guide groove. In this application, after the pull rope extends through the limiting port, the limiting port effectively limits the range of swaying of the pull rope. Because the limiting port and the fixing screw are staggered, if the pull rope becomes slack or sways, the limiting port can prevent the pull rope from getting tangled around the screw head.

[0083] When installing the drive assembly, first pass the claw part through the first clearance slot and the positioning part through the second clearance slot, thus assembling the shock-absorbing pad onto the back plate. Then, insert the positioning part into the insertion hole and engage the claw part in the slot. At this point, the back plate is fixed to the mounting plate, with the shock-absorbing pad positioned between them. This completes the positioning and initial fixing between the motor housing and the mounting plate, eliminating the need for manual support. Screws and fasteners can then be used to further secure the motor housing to the mounting plate, effectively improving installation efficiency.

[0084] When the drive gear rotates, it causes the groove to rotate synchronously, forming a first trajectory. Under the action of the spring, the moving part remains on the first trajectory. When the groove rotates to the position corresponding to the moving part, the moving part enters the groove, forming a second trajectory as it moves. At this time, the moving part contacts the triggering part, triggering it. Upon receiving the trigger signal, the controller controls the rotation state of the drive gear, such as stopping or reversing it. Thus, through ingenious structural design, an accurate triggering and response mechanism is formed, facilitating efficient control of the rotation state of the drive assembly.
