[0038] Referring to Figures 1 to 15, this application provides a refrigerator 530, which includes shelves.

[0039] In some embodiments, the shelf includes a shelf body 100, a first anti-tipping part 500, and a controller 520. The shelf body 100 is disposed on the mounting assembly 120, and is in place when in the mounting position and out of place when in the non-mounting position. The first anti-tipping part 500 is disposed on the shelf body 100 and includes a first anti-tipping part 500 having a first state and a second state. The first anti-tipping part 500 remains in the first state when the shelf body 100 is in place, and changes to the second state when the shelf body 100 is out of place. The controller 520 is electrically connected to the first anti-tipping part 500 and is configured to determine whether the shelf body 100 is out of place based on the state of the first anti-tipping part 500.

[0040] In this embodiment, the shelf body 100 is mounted on the mounting assembly 120. "In position" means the shelf body 100 is in the installed position, and "out of position" means the shelf body 100 is in a non-installed position, such as tilting, tipping over, or falling relative to the installed position. When a first anti-tipping part 500 is provided, its state can change according to the position of the shelf body 100. When the first anti-tipping part 500 maintains a first state, the controller 520 determines that the shelf body 100 is in position; when the first anti-tipping part 500 changes to a second state, the controller 520 determines that the shelf body 100 is out of position. This allows for timely detection of shelf body 100 out of position, facilitating further operation of the shelf.

[0041] In some embodiments, as shown in Figures 1 to 3, the shelf includes a shelf body 100, a mounting assembly 120, a first drive structure, and a second drive structure. The mounting assembly 120 includes a slide rail 121, along which the shelf body 100 can slide up and down. The first drive mechanism includes a first motor 141 and a first pull rope 151. The first motor 141 is connected to a first side of the shelf body 100 via the first pull rope 151 and is used to drive the first pull rope 151 to move. The second drive mechanism includes a second motor 142 and a second pull rope 152. The second motor 142 is connected to a second side of the shelf body 100 via the second pull rope 152 and is used to drive the second pull rope 152 to move. Furthermore, when the first pull rope 151 and the second pull rope 152 move synchronously, they cause the shelf body 100 to rise and fall.

[0042] In this embodiment, two drive mechanisms are used to raise and lower the shelf body 100. A first motor 141 pulls the first side of the shelf body 100 via a first pull rope 151, and a second motor 142 pulls the second side of the shelf body 100 via a second pull rope 152. Thus, when the first pull rope 151 and the second pull rope 152 move upwards synchronously, the shelf body 100 rises along the slide rail 121; when the first pull rope 151 and the second pull rope 152 move downwards synchronously, the shelf body 100 descends along the slide rail 121 under gravity. This allows the user to automatically adjust the height of the shelf body 100 according to actual height requirements, accommodating the storage needs of different items.

[0043] Optionally, as shown in FIG1, the first drive mechanism further includes a first winding wheel 161. A first end of the first pull rope 151 is connected to the first winding wheel 161, and a second end of the first pull rope 151 is connected to the shelf body 100; the first motor 141 can drive the first winding wheel 161 to rotate to wind or release the first pull rope 151.

[0044] In this embodiment, the drive shaft of the first motor 141 is connected to the first winding wheel 161 via a transmission gear set 170, thereby driving the winding wheel 161 to rotate. When the first winding wheel 161 rotates, it winds or releases the first pull rope 151. When the first winding wheel 161 winds the first pull rope 151, the first pull rope 151 pulls the shelf body 100 to slide upward along the slide rail 121; when the first winding wheel 161 releases the first pull rope 151, the shelf body 100 slides downward along the slide rail 121 under the action of gravity, thereby realizing the raising and lowering of the shelf body 100.

[0045] Optionally, as shown in FIG2, the first drive mechanism further includes a first gear 171 and a first rack 181. A first motor 141 is used to drive the first gear 171 to rotate; the first rack 181 meshes with the first gear 171, and the first end of the first pull rope 151 is connected to the first rack 181, and the second end of the first pull rope 151 is connected to the shelf body 100; and when the first gear 171 rotates, the position of the first pull rope 151 is adjusted by the first rack 181.

[0046] In this embodiment, the drive shaft of the first motor 141 is connected to the first gear 171 via a set of transmission gears 170, thereby driving the first gear 171 to rotate. Furthermore, when the first gear 171 rotates, it drives the first rack 181 to move, adjusting the position of the first pull rope 151. When the first rack 181 drives the first pull rope 151 upward, the first pull rope 151 pulls the shelf body 100 upward along the slide rail 121; when the first rack 181 drives the first pull rope 151 downward, the shelf body 100 slides downward along the slide rail 121 under gravity, thus realizing the raising and lowering of the shelf body 100.

[0047] Optionally, the first rack 181 is located above the shelf body 100, and the first rack 181 is arranged parallel to the slide rail 121.

[0048] In this embodiment, the upper end of the first rack 181 meshes with the first gear 171, and the lower end of the first rack 181 is connected to the upper end of the first pull rope 151. When the first rack 181 moves upward, the shelf body 100 rises; when the first rack 181 moves downward, the shelf body 100 falls.

[0049] Optionally, as shown in Figure 1, the second drive mechanism further includes a second winding wheel 162. The first end of the second pull rope 152 is connected to the second winding wheel 162, and the second end of the second pull rope 152 is connected to the shelf body 100; the second motor 142 can drive the second winding wheel 162 to rotate to wind or release the second pull rope 152.

[0050] In this embodiment, the drive shaft of the second motor 142 is connected to the second winding wheel 162 via a transmission gear set 170, thereby driving the winding wheel 162 to rotate. When the second winding wheel 162 rotates, it winds or releases the second pull rope 152. When the second winding wheel 162 winds the second pull rope 152, the pull rope 150 pulls the shelf body 100 to slide upward along the slide rail 121; when the second winding wheel 162 releases the second pull rope 152, the shelf body 100 slides downward along the slide rail 121 under the action of gravity, thereby realizing the raising and lowering of the shelf body 100.

[0051] Optionally, as shown in Figure 2, the second drive mechanism further includes a second gear 172 and a second rack 182. A second motor 142 drives the second gear 172 to rotate; the second rack 182 meshes with the second gear 172, and the first end of the second pull rope 152 is connected to the second rack 182, while the second end of the second pull rope 152 is connected to the shelf body 100; furthermore, when the second gear 172 rotates, the position of the second pull rope 152 is adjusted via the second rack 182.

[0052] In this embodiment, the drive shaft of the second motor 142 is connected to the second gear 172 via a transmission gear set 170, thereby driving the second gear 172 to rotate. When the second gear 172 rotates, it drives the second rack 182 to move, and the movement of the second rack 182 adjusts the position of the second pull rope 152. When the second rack 182 drives the second pull rope 152 to move upward, the second pull rope 152 pulls the shelf body 100 to slide upward along the slide rail 121; when the second rack 182 drives the second pull rope 152 to move downward, the shelf body 100 slides downward along the slide rail 121 under the action of gravity, thereby realizing the raising and lowering of the shelf body 100.

[0053] Optionally, the second rack 182 is located above the shelf body 100, and the second rack 182 is arranged parallel to the slide rail 121.

[0054] In this embodiment, the upper end of the second rack 182 meshes with the second gear 172, and the lower end of the second rack 182 is connected to the upper end of the second pull rope 152. When the second rack 182 moves upward, the shelf body 100 rises; when the second rack 182 moves downward, the shelf body 100 falls.

[0055] Optionally, as shown in Figure 3, the mounting assembly 120 also includes a slider 122, which can be slidably connected to the slide rail 121; and the two slide rails 121 are arranged in parallel, and both sides of the shelf are raised and lowered along the corresponding slide rail 121 via the slider 122.

[0056] In this embodiment, the parallel slide rails 121 ensure the stability of the shelf during lifting and lowering, avoiding safety issues caused by excessive tilting or swaying. Furthermore, both sides of the shelf are supported by sliders 122 that move along the slide rails 121, forming a double-sided support structure, which ensures the shelf remains stable even when carrying heavy loads.

[0057] Optionally, each of the two sliders 122 is provided with a movable pulley 130, wherein the first pull rope 151 is connected to the first side of the shelf body 100 through one movable pulley 130, and the second pull rope 152 is connected to the second side of the shelf body 100 through the other movable pulley 130; and the first motor 141 drives the corresponding movable pulley 130 to move through the first pull rope 151, and the second motor 142 drives the corresponding movable pulley 130 to move through the second pull rope 152, thereby the two movable pulleys 130 drive the shelf body 100 to rise and fall through the corresponding sliders 122.

[0058] In this embodiment, both the first pull rope 151 and the second pull rope 152 are connected to the shelf body 100 via a movable pulley 130. When the first motor 141 adjusts the position of the first pull rope 151, the corresponding movable pulley 130 moves along the first pull rope 151; when the second motor 142 adjusts the position of the second pull rope 152, the corresponding movable pulley 130 moves along the second pull rope 152. When the two movable pulleys 130 move synchronously, they drive the shelf body 100 to rise and fall via the corresponding slider 122. In this way, due to the labor-saving characteristics of the movable pulley 130, the two motors can drive the shelf body 100 to move with a smaller driving force, which helps to reduce the torque of the two motors.

[0059] It should be noted that the first and second drive structures can both be made using a wound wheel structure, or both using a gear and rack structure, or one using a wound wheel structure and the other using a gear and rack structure. All of the above should be covered within the protection scope of this utility model.

[0060] This disclosure also provides a refrigerator 530, including the shelves described in any of the above embodiments.

[0061] In this embodiment, the refrigerator 530 has a cabinet with shelves disposed inside; and a slide rail 121 is vertically arranged on the inner wall of the cabinet. The automatic lifting and lowering adjustment of the shelves is achieved through the cooperation of two drive structures, allowing the user to adjust the height of the shelves according to storage needs. In this way, the internal space of the refrigerator 530 is effectively utilized, and the refrigerator 530 is more intelligent to use, improving convenience.

[0062] In some embodiments, as shown in FIG4, the shelf uses a motor 140 and a winding wheel 160 to drive the shelf body 100 to rise and fall via pull ropes 150. The motor 140 drives the winding wheel 160 to rotate, and the winding wheel 160 is connected to both sides of the shelf body 100 via two pull ropes 150. When the winding wheel 160 winds the pull ropes 150, the two pull ropes 150 respectively pull the two sides of the shelf body 100 upwards along the slide rail 121; when the winding wheel 160 releases the pull ropes 150, the shelf body 100 slides downwards along the slide rail 121 under the action of gravity, thereby realizing the rising and falling of the shelf body 100.

[0063] In some embodiments, as shown in FIG5, the shelf uses a motor 140 and a gear 170 to drive the shelf body 100 to rise and fall via pull ropes 150. Two racks 180 are respectively engaged with the two sides of the gear 170; and the first ends of the two pull ropes 150 are respectively connected to the two racks 180, and the second ends of the two pull ropes 150 are respectively connected to the two sides of the shelf body 100. When the two racks 180 drive the corresponding pull ropes 150 upward, the two pull ropes 150 pull the two sides of the shelf body 100 upward along the slide rail 121; when the two racks 180 drive the corresponding pull ropes 150 downward, the shelf body 100 slides downward along the slide rail 121 under the action of gravity, thereby realizing the rising and falling of the shelf body 100.

[0064] In some embodiments, as shown in Figures 9 and 10, the first anti-tipping part 500 includes a magnet 300, a detection sensor 310, and a controller 520; wherein, the magnet 300 is disposed on the shelf body 100, and the magnet 300 has a first magnetic field when the shelf body 100 is in place, and the magnet 300 has a second magnetic field when the shelf body 100 is out of place; the detection sensor 310 is used to detect changes in the magnetic field of the magnet 300 and is electrically connected to the controller 520; and, when the detection sensor 310 detects that the magnet 300 forms a second magnetic field, the controller 520 determines that the shelf body 100 is out of place.

[0065] In this embodiment, the shelf body 100 is mounted on the mounting assembly 120. "In place" means the shelf body 100 is in a normally installed state, while "out of place" means the shelf body 100 has become abnormally installed, such as tilting, tipping over, or falling off relative to its normal installation position. Since the magnet 300 is mounted on the shelf body 100, if the shelf body 100 becomes out of place during use, the magnet 300 moves with the shelf body 100. At this time, the magnetic field of the magnet 300 changes synchronously, from a first magnetic field to a second magnetic field. Furthermore, the detection sensor 310 transmits the magnetic field change signal to the controller 520, which determines that the shelf body 100 is out of place. This allows for timely detection of shelf body 100 misalignment, facilitating further operation of the shelf.

[0066] Optionally, the mounting assembly 120 includes a slide rail 121 and a slider 122. The slide rail 121 is arranged vertically, and the slider 122 can be slidably connected to the slide rail 121. A cantilever 110 is provided on the side of the shelf body 100, and the cantilever 110 is connected to the slider 122, so that the shelf body 100 can be raised and lowered along the slide rail 121 via the slider 122. In position corresponds to the shelf body 100 remaining horizontal, and out of position corresponds to the shelf body 100 becoming tilted.

[0067] In this embodiment, as shown in Figure 9, the shelf body 100 is normally installed on the slide rail 121 and remains horizontal to facilitate the placement of items; at this time, the shelf body 100 is in position. The shelf body 100 can be raised and lowered along the slide rail 121. If tilting occurs during the raising and lowering process, the shelf body 100 will become displaced. As shown in Figure 10, in some possible situations, such as the first locking shaft 113 breaking, or the positive latch hook 111 becoming loose from the first locking shaft 113, the shelf body 100 will be subjected to a downward force, causing it to tilt downward or even fall.

[0068] Optionally, the shelf also includes a motor 140. The motor 140 is electrically connected to the controller 520 and is used to drive the shelf body 100 to rise and fall; during the rising and falling of the shelf body 100, if the controller 520 determines that the shelf body 100 is tilted, the controller 520 controls the motor 140 to stop.

[0069] In this embodiment, if the shelf body 100 continues to rise or fall while out of position, the placed items will tip over or even roll off. Therefore, when the controller 520 determines that the shelf body 100 is tilted, the controller 520 controls the motor 140 to stop. This effectively prevents the placed items from tipping over or rolling off, ensuring the stability of the shelf body 100's rise and fall.

[0070] Optionally, the magnet 300 is disposed on the cantilever 110; the detection sensor 310 is disposed on the slider 122, and the detection sensor 310 corresponds to the magnet 300.

[0071] In this embodiment, since the shelf body 100 is connected to the slider 122 via the cantilever 110, the detection sensor 310 moves synchronously with the slider 122 during the lifting and lowering process of the shelf body 100. Furthermore, the cantilever 110 tilts synchronously when the shelf body 100 tilts. Thus, when the magnetic field of the magnet 300 changes, it will be quickly captured by the detection sensor 310, thereby instantly triggering the response of the controller 520.

[0072] Optionally, the magnet 300 includes a permanent magnet 300. The permanent magnet 300 can continuously generate a magnetic field without requiring an external power supply. Furthermore, the magnetic field strength of the permanent magnet 300 is relatively stable and will not change significantly due to minor changes in external factors (such as temperature, humidity, etc.). This ensures that the detection sensor 310 can stably detect changes in the magnetic field of the permanent magnet 300.

[0073] Optionally, the detection sensor 310 includes a Hall sensor. Hall sensors offer high measurement accuracy, particularly when measuring changes in the magnetic field. Thus, when the shelf body 100 experiences a slight tilt or misalignment, the Hall sensor can accurately detect the change in the magnetic field, thereby triggering a timely response from the controller 520.

[0074] Optionally, the slider 122 is provided with a movable pulley 130; the drive mechanism also includes a pull rope 150, the first end of which is connected to the motor 140 and the second end of which is connected to the movable pulley 130; and the motor 140 drives the movable pulley 130 to move through the pull rope 150, and then the movable pulley 130 drives the shelf body 100 to rise and fall through the slider 122.

[0075] In this embodiment, the motor 140 can be connected to the first end of the pull rope 150 via a winding wheel structure or a gear and rack structure. The implementation methods of the winding wheel structure and the gear and rack structure are detailed in the first to third embodiments and will not be repeated here. Thus, when the motor 140 adjusts the position of the pull rope 150, the movable pulley 130 moves along the pull rope 150, thereby driving the shelf body 100 to rise and fall. Furthermore, due to the labor-saving characteristics of the movable pulley 130, the motor 140 can move the shelf body 100 with less driving force, which helps to reduce the torque of the motor 140.

[0076] Optionally, as shown in Figure 14, the mounting assembly 120 includes a bracket 190, to which the shelf body 100 is fixed; and, when in position, the shelf body 100 remains horizontal, and when out of position, the shelf body 100 becomes tilted. A magnet 300 is disposed on the shelf body 100; a detection sensor 310 is disposed on the bracket 190, and the detection sensor 310 corresponds to the magnet 300.

[0077] In this embodiment, the shelf body 100 is fixedly connected to the support 190 and does not have a lifting function. When the shelf is used for a long time or carries heavy items, the connection between the shelf body 100 and the support 190 may loosen. Under the action of the first anti-tipping part 500, if the shelf body 100 becomes loose and tilts, the magnetic field of the magnet 300 changes synchronously. The detection sensor 310 transmits the magnetic field change signal to the controller 520, which determines that the shelf body 100 is out of position. Thus, the shelf body 100 is promptly detected as out of position, allowing for a secure connection between the shelf body 100 and the support 190. It can be seen that the first anti-tipping part 500 in this embodiment is applicable to both shelves with and without lifting functions.

[0078] This disclosure also provides a refrigerator 530, including the shelves described in any of the above embodiments.

[0079] In this embodiment, the refrigerator 530 has a cabinet, and a shelf is disposed inside the cabinet. Items are placed on top of the shelf body 100. Furthermore, if the shelf body 100 becomes displaced, it can be promptly detected by the first anti-tipping part 500, composed of a magnet 300 and a detection sensor 310, allowing for further manipulation of the shelf. This helps protect the items inside the refrigerator 530 and reduces unnecessary losses.

[0080] In some embodiments, as shown in Figures 11 to 13, the first anti-tipping part 500 includes a micro switch 400 and a controller 520 electrically connected; the micro switch 400 includes a contact 410 and a trigger 420, the contact 410 being disposed on the shelf body 100, and the trigger 420 being disposed on one side of the contact 410; wherein, when the shelf body 100 is in position, the contact 410 and the trigger 420 abut against each other to close the micro switch 400, and when the shelf body 100 is out of position, the contact 410 and the trigger 420 separate to open the micro switch 400; and, when the micro switch 400 is open, the controller 520 determines that the shelf body 100 is out of position.

[0081] In this embodiment, the shelf body 100 is mounted on the mounting assembly 120. "In position" means the shelf body 100 is in a normally installed state, while "out of position" means the shelf body 100 has become abnormally installed, such as tilting, tipping over, or falling off relative to its normal installation position. Since the contact element 410 is disposed on the shelf body 100, if the shelf body 100 becomes out of position during use, the contact element 410 moves with the shelf body 100 and separates from the trigger element 420. Furthermore, the microswitch 400 transmits a disconnect signal to the controller 520, which determines that the shelf body 100 is out of position. This allows for timely detection of shelf body 100 misalignment, facilitating further operation of the shelf.

[0082] Optionally, the mounting assembly 120 includes a slide rail 121 and a slider 122. The slide rail 121 is arranged vertically, and the slider 122 can be slidably connected to the slide rail 121. A cantilever 110 is provided on the side of the shelf body 100, and the cantilever 110 is connected to the slider 122, so that the shelf body 100 can be raised and lowered along the slide rail 121 via the slider 122. In position corresponds to the shelf body 100 remaining horizontal, and out of position corresponds to the shelf body 100 becoming tilted.

[0083] In this embodiment, as shown in Figure 11, the shelf body 100 is normally installed on the slide rail 121 and remains horizontal to facilitate the placement of items; at this time, the shelf body 100 is in position. The shelf body 100 can be raised and lowered along the slide rail 121. If tilting occurs during the raising and lowering process, the shelf body 100 will become displaced. As shown in Figure 11, the shelf body 100 is tilted upward due to an upward force.

[0084] Optionally, the shelf also includes a motor 140. The motor 140 is electrically connected to the controller 520 and is used to drive the shelf body 100 to rise and fall; during the rising and falling of the shelf body 100, if the controller 520 determines that the shelf body 100 is tilted, the controller 520 controls the motor 140 to stop.

[0085] In this embodiment, if the shelf body 100 continues to rise or fall while out of position, the placed items will tip over or even roll off. Therefore, when the controller 520 determines that the shelf body 100 is tilted, the controller 520 controls the motor 140 to stop. This effectively prevents the placed items from tipping over or rolling off, ensuring the stability of the shelf body 100's rise and fall.

[0086] Optionally, the contact 410 is disposed on the cantilever 110; the trigger 420 is disposed on the slider 122, and the trigger 420 corresponds to the contact 410.

[0087] In this embodiment, since the shelf body 100 is connected to the slider 122 via the cantilever 110, when the shelf body 100 is in position and during lifting and lowering, the trigger 420 moves synchronously with the slider 122 and always abuts against the contact 410 on the cantilever 110. When the shelf body 100 tilts, the cantilever 110 tilts synchronously, and the contact 410 moves synchronously with the cantilever 110 and separates from the trigger 420. At this time, the micro switch 400 is turned off, thereby instantly triggering the response of the controller 520. Here, the trigger 420 can be disposed on either cantilever 110 on both sides of the shelf body 100.

[0088] Optionally, as shown in Figure 11, the slider 122 is provided with a first locking shaft 113, and the end of the cantilever 110 is provided with a downward-facing positive hook 111; the cantilever 110 is engaged with the first locking shaft 113 through the positive hook 111, and the positive hook 111 serves as a contact element 410.

[0089] In this embodiment, the snap-fit ​​hook 111 and the first snap-fit ​​shaft 113 are designed to snap together, allowing the shelf body 100 to be quickly and easily installed onto the slider 122 via the cantilever 110, and also easily removed from the slider 122. Furthermore, the snap-fit ​​hook 111 also functions as a contact element 410, exhibiting high sensitivity. When the shelf body 100 tilts, the snap-fit ​​hook 111 moves synchronously, thus separating from the trigger element 420.

[0090] Optionally, the slider 122 is provided with a second locking shaft 114, and the end of the cantilever 110 is provided with an upward-facing inverted hook 112; the cantilever 110 is engaged with the second locking shaft 114 by the inverted hook 112, and the inverted hook 112 serves as a contact element 410.

[0091] In this embodiment, the inverted hook 112 and the second locking shaft 114 adopt a snap-fit ​​design, so that the shelf body 100 can be quickly and easily installed onto the slider 122 via the cantilever 110, and can also be easily removed from the slider 122. Furthermore, the inverted hook 112 also serves as a contact element 410, exhibiting high sensitivity. When the shelf body 100 tilts, the inverted hook 112 moves synchronously, thus separating from the trigger element 420. Here, the opening of the positive hook 111 faces downwards, and the opening of the inverted hook 112 faces upwards. During installation, the hooks snap from top to bottom. The first locking shaft 113 exerts an upward force on the positive hook 111, thereby supporting the shelf body 100; the second locking shaft 114 exerts a downward force on the inverted hook 112, thereby preventing the shelf body 100 from tipping over.

[0092] Optionally, as shown in Figure 13, both the forward-facing hook 111 and the reverse-facing hook 112 serve as a contact element 410, and two corresponding trigger elements 420 are respectively provided on the slider 122. This forms two sets of microswitches, and either microswitch will transmit an open signal to the controller 520, which will then determine that the shelf body 100 is out of position.

[0093] Optionally, the slider 122 is provided with a movable pulley 130; the drive mechanism also includes a pull rope 150, the first end of which is connected to the motor 140 and the second end of which is connected to the movable pulley 130; and the motor 140 drives the movable pulley 130 to move through the pull rope 150, and then the movable pulley 130 drives the shelf body 100 to rise and fall through the slider 122.

[0094] In this embodiment, the motor 140 can be connected to the first end of the pull rope 150 via a winding wheel structure or a gear and rack structure. The implementation methods of the winding wheel structure and the gear and rack structure are detailed in the first to third embodiments and will not be repeated here. Thus, when the motor 140 adjusts the position of the pull rope 150, the movable pulley 130 moves along the pull rope 150, thereby driving the shelf body 100 to rise and fall. Furthermore, due to the labor-saving characteristics of the movable pulley 130, the motor 140 can move the shelf body 100 with less driving force, which helps to reduce the torque of the motor 140.

[0095] Optionally, the mounting assembly 120 includes a bracket 190, to which the shelf body 100 is fixed; and, when in position, the shelf body 100 remains horizontal, and when out of position, the shelf body 100 becomes tilted. A contact 410 is disposed on the shelf body 100; a trigger 420 is disposed on the bracket 190, and the trigger 420 corresponds to the contact 410.

[0096] In this embodiment, the shelf body 100 is fixedly connected to the support 190 and does not have a lifting function. When the shelf is used for a long time or carries heavy items, the connection between the shelf body 100 and the support 190 may loosen. Under the action of the first anti-tipping part 500, once the shelf body 100 becomes loose and tilts, the contact member 410 separates from the trigger member 420. The microswitch 400 transmits a disconnect signal to the controller 520, which determines that the shelf body 100 is out of position. Thus, the shelf body 100 is promptly detected as out of position, allowing for a secure connection between the shelf body 100 and the support 190. It can be seen that the first anti-tipping part 500 in this embodiment is applicable to both shelves with and without lifting functions.

[0097] In some embodiments, as shown in Figures 6 to 8, the shelf further includes a drive mechanism and a second anti-tipping part 510. The shelf body 100 is height-adjustable; the drive mechanism includes a motor 140 for driving the shelf body 100 to rise and fall; the second anti-tipping part 510 includes a radiation component 200 and a controller 520. The radiation component 200 is disposed on the shelf body 100, and both the radiation component 200 and the motor 140 are electrically connected to the controller 520. The radiation component 200 includes an emitting end 210 and a receiving end 220, wherein the emitting end 210 is located below the shelf body 100 and is used to emit detection light, and the receiving end 220 is used to receive the detection light. Furthermore, during the descent of the shelf body 100, if the detection light is blocked by an item, causing the receiving end 220 to not receive a signal, the controller 520 controls the motor 140 to stop.

[0098] In this embodiment, the upper part of the shelf body 100 is used for placing items, and the lower part of the shelf body 100 is provided with a ray assembly 200. When the receiving end 220 receives a signal, it indicates that the detection light is not obstructed, meaning there are no items obstructing the lower part of the shelf body 100, and the conditions for descent are met. When the receiving end 220 does not receive a signal, it indicates that the detection light is obstructed, meaning there are items obstructing the lower part of the shelf body 100, and the conditions for descent are not met. If the shelf is descending at this time, the controller 520 controls the motor 140 to stop. In this way, during the descent process, the shelf body 100 can avoid collision with obstructing items below it, preventing the shelf body 100 from tilting, and thus effectively preventing the placed items from tipping over.

[0099] Optionally, as shown in Figure 8, multiple shelf bodies 100 are arranged sequentially from top to bottom, and each shelf body 100 is provided with a ray assembly 200; and, when a shelf body 100 is rising, and the receiving end 220 of the shelf body 100 above it does not receive a signal, the controller 520 controls the motor 140 to stop.

[0100] In this embodiment, it is understood that each shelf body 100 can achieve independent lifting and lowering by using a separate drive mechanism. When an item is placed on a shelf body 100, if the shelf body 100 rises a significant distance, the item may collide with the shelf body 100 above it. During the lifting process, if the receiver 220 of the shelf body 100 above it does not receive a signal, it indicates that the detection light is blocked by the placed item. At this time, the controller 520 controls the corresponding motor 140 to stop. This avoids collisions between items on the rising shelf body 100 and adjacent shelf bodies 100 above it, effectively preventing the placed items from tipping over.

[0101] Optionally, the second anti-tipping part 510 further includes a reflective assembly 230. The reflective assembly 230 is disposed on the shelf body 100 and includes a first mirror 231 and a second mirror 232; the first mirror 231 and the second mirror 232 are both located below the shelf body 100 and arranged opposite to each other; the emitting end 210 emits detection light at an inclined angle toward either mirror so that the detection light is reflected between the two mirrors; and the receiving end 220 is located at either reflection point.

[0102] In this embodiment, by emitting detection light towards either mirror surface via the transmitter 210 and reflecting it between the two mirror surfaces, a relatively stable detection area can be formed below the shelf body 100 (as shown by the dotted line in Figure 7). Furthermore, the receiver 220 is positioned at any reflection point, ensuring that it can stably receive the detection light. This facilitates more accurate detection of whether there are obstructions below the shelf body 100, thereby improving detection precision.

[0103] Optionally, the first mirror 231 and the second mirror 232 are parallel to each other. In this way, the reflection between the parallel mirrors can reduce the scattering and loss of the detection light, ensuring that the receiver 220 can receive sufficient detection light.

[0104] Optionally, as shown in FIG7, along the length direction of the first mirror 231, the transmitting end 210 is disposed at one end of the first mirror 231, and the receiving end 220 is disposed at the other end of the first mirror 231.

[0105] In this embodiment, since the transmitting end 210 and the receiving end 220 are located at opposite ends of the mirror, the detection light travels a longer distance between the two mirrors. This allows the detection light to cover a wider area, thereby expanding the detection range and improving detection sensitivity.

[0106] Optionally, as shown in Figure 6, the shelf body 100 has opposing cantilever arms 110 on both sides, and the opposing surfaces of the two cantilever arms 110 serve as the first mirror surface 231 and the second mirror surface 232, respectively. In this way, the surfaces of the cantilever arms 110 are directly used as mirrors for the reflective assembly 230, which not only saves additional materials but also simplifies the structure of the entire shelf.

[0107] Optionally, the light being detected includes infrared light.

[0108] In this embodiment, the transmitter 210 is an infrared generator, and the receiver 220 is an infrared receiver. Infrared detection technology is relatively mature, and because infrared light has a long wavelength, it is not easily interfered with by visible light or other electromagnetic waves. Thus, infrared light, as a detection light, can maintain high stability and accuracy in complex environments.

[0109] Optionally, the shelf also includes a mounting assembly 120, which includes a slide rail 121 and a slider 122. The slide rail 121 is arranged along the lifting direction of the shelf body 100, and the shelf body 100 is connected to the slide rail 121 via the slider 122, with a movable pulley 130 provided on the slider 122. The drive mechanism also includes a pull rope 150, with a first end connected to a motor 140 and a second end connected to the movable pulley 130; the motor 140 drives the movable pulley 130 to move via the pull rope 150, and the movable pulley 130 drives the shelf body 100 to rise and fall via the slider 122.

[0110] In this embodiment, the motor 140 can be connected to the first end of the pull rope 150 via a winding wheel structure or a gear and rack structure. The implementation methods of the winding wheel structure and the gear and rack structure are detailed in the first to third embodiments and will not be repeated here. Thus, when the motor 140 adjusts the position of the pull rope 150, the movable pulley 130 moves along the pull rope 150, thereby driving the shelf body 100 to rise and fall. Furthermore, due to the labor-saving characteristics of the movable pulley 130, the motor 140 can move the shelf body 100 with less driving force, which helps to reduce the torque of the motor 140.

[0111] This disclosure also provides a refrigerator 530, including the shelves described in any of the above embodiments.

[0112] In this embodiment, the refrigerator 530 has a cabinet with shelves disposed inside; and a slide rail 121 is vertically arranged on the inner wall of the cabinet. The user can adjust the height of the shelves according to storage needs, and the ray assembly 200 prevents the shelf body 100 from tilting during lifting, thus effectively preventing the placed items from tipping over. In this way, the internal space of the refrigerator 530 is effectively utilized, and the refrigerator 530 is more intelligent to use, improving convenience.

[0113] This disclosure also provides a refrigerator 530, including the shelves described in any of the above embodiments.

[0114] In this embodiment, the refrigerator 530 has a cabinet, and a shelf is disposed inside the cabinet. Items are placed on top of the shelf body 100. Furthermore, if the shelf body 100 becomes displaced, the first anti-tipping part 500, composed of microswitches, can promptly detect this, allowing for further operation of the shelf. This helps protect the items inside the refrigerator 530 and reduces unnecessary losses.

[0115] Optionally, as shown in Figure 15, the refrigerator 530 also includes a fixed shelf 540, which is positioned above the shelf body 100, and a ray assembly 200 is also provided below the fixed shelf 540. Furthermore, if the receiving end 220 of the fixed shelf 540 does not receive a signal during the rising of the shelf body 100, the controller 520 stops the motor. This prevents items on the rising shelf body 100 from colliding with the fixed shelf 540 above it, thereby effectively preventing the placed items from tipping over.

[0116] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary.
