Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a shelf mechanism and a refrigerator. Background Technology

[0002] In some refrigerators, the shelves tend to sway along the direction of movement when pushed in or pulled out, which may cause friction and collision between the shelves and the side walls of the refrigerator. Summary of the Invention

[0003] This application provides a shelf mechanism and a refrigerator to solve the technical problem that in some existing refrigerators, the shelf tends to sway along both sides of the shelf's moving direction during the process of pushing the shelf in or pulling it out, which may cause the shelf to rub and collide with the side wall of the refrigerator body.

[0004] To address the aforementioned technical problems, this application proposes a shelf mechanism, comprising: a shelf; a rotating mechanism disposed on a mounting platform fixed plate, the rotating mechanism being used to drive the shelf to rotate around the rotating axis of the rotating mechanism; and a locking mechanism, the locking mechanism including an electric locking assembly, the electric locking assembly including a drive rod and a drive member, the drive member being disposed on the mounting platform fixed plate, the drive rod being connected to the drive shaft of the drive member, and the drive rod being releasably inserted into the rotating mechanism via the drive member.

[0005] The rotating mechanism includes a fixed part and a rotating part. The rotating part is rotatably connected to the fixed part. The fixed part is used to detachably connect to the mounting plate of the platform to be installed. The rotating part is used to drive the shelf to rotate around the rotating axis of the rotating mechanism. Several limiting grooves are formed on the outer periphery of the rotating part. The drive rod can be detachably inserted into the limiting groove through the drive component.

[0006] The electric locking assembly also includes a sensing component, which is signal-connected to the drive unit. The drive unit drives the drive rod to engage or disengage with the limiting groove based on the rotation signal sensed by the sensing component.

[0007] The locking mechanism also includes a mechanical locking component, which is mounted on the mounting plate of the platform to be installed. The mechanical locking component can be released and abutted against the limiting groove.

[0008] The mechanical locking assembly and the electric locking assembly are located at both ends of the rotating mechanism.

[0009] The limiting groove includes a first sub-groove and two second sub-grooves. When the shelf is in the first state, the mechanical locking assembly abuts against the first sub-groove; when the shelf is in the second state, the mechanical locking assembly abuts against the second sub-grooves, and the drive rod is inserted into the second sub-groove.

[0010] The two second sub-grooves are located on the same diameter of the rotating part.

[0011] The limiting groove includes a third sub-groove, and when the shelf is in the first state, the drive rod is inserted into the third sub-groove.

[0012] The third sub-groove and the first sub-groove are located on the same diameter of the rotating part.

[0013] To solve the above-mentioned technical problems, this application proposes a refrigerator, which includes the shelf mechanism described above.

[0014] In this application, the rotating mechanism of the shelf structure drives the shelf to rotate around its rotation axis, allowing consumers to view and store items. The locking mechanism includes an electric locking assembly, which comprises a drive rod and a drive component. The drive rod is connected to the drive shaft of the drive component, and the drive rod is releasably inserted into the rotating mechanism via the drive component. Through this method, the rotating mechanism can be forcibly locked or unlocked, ensuring that the shelf moves in a straight line along its direction of movement and preventing friction and collision between the shelf and external devices (such as a refrigerator).

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0028] The refrigerator provided by the present invention will be described in detail below with reference to the embodiments.

[0029] Please see Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a schematic diagram of the structure of the refrigerator according to the first embodiment of this application; Figure 2 This is a first partial schematic diagram of the first embodiment of the refrigerator of this application; Figure 3 This is a partial schematic diagram of the second embodiment of the refrigerator of this application. In one embodiment, the refrigerator 10 includes a refrigerator body 101 and a shelf mechanism (not shown in the figure), the shelf mechanism being disposed within the refrigerator body 101. The shelf mechanism includes a shelf 1, a rotating mechanism 4, a slide rail mechanism 5, and a locking mechanism 6. The shelf 1, rotating mechanism 4, slide rail mechanism 5, and locking mechanism 6 are all disposed within the refrigerator body 101. The slide rail mechanism 5 is disposed on the inner side wall of the refrigerator body 101, and is used to drive the shelf 1 to push and pull within the refrigerator body 101. The rotating mechanism 4 is disposed between the slide rail mechanism 5 and the shelf 1. The shelf 1 and the rotating mechanism 4 can move along the slide rail mechanism 5, realizing the back-and-forth pushing and pulling of the shelf 1, and the shelf 1 and the rotating mechanism 4 being pushed and pulled to the outside of the refrigerator body 101.

[0030] The aforementioned slide rail mechanism 5 includes a sliding plate 51 and a guide rail fixing plate 52. The sliding plate 51 is used to mount the rotating mechanism 4 and the locking mechanism 6, etc. The guide rail fixing plate 52 is used to mount on the refrigerator 10 and other devices. The sliding plate 51 and the guide rail fixing plate 52 are slidably connected, and the sliding plate 51 can slide relative to the guide rail fixing plate 52. That is, the slide rail mechanism 5 is used to drive the shelf 1 to slide along the extension direction of the slide rail mechanism 5. The rotating mechanism 4 is located between the shelf 1 and the slide rail mechanism 5.

[0031] The shelf mechanism provided in this application has an original state, an initial state, and a rotating state. In the original state, shelf 1 is located inside the refrigerator 10, with the sliding plate 51 and guide rail fixing plate 52 in a retracted state. The rotating mechanism 4 does not rotate, and therefore shelf 1 does not rotate. In the initial state, shelf 1 is located outside the refrigerator 10, with the sliding plate 51 and guide rail fixing plate 52 in an extended state. The rotating mechanism 4 does not rotate relative to the sliding plate 51, and therefore shelf 1 does not rotate. Through the sliding connection between the sliding plate 51 and the guide rail fixing plate 52, the shelf mechanism can switch back and forth between the original and initial states. In the rotating state, shelf 1 is located outside the refrigerator 10, with the sliding plate 51 and guide rail fixing plate 52 in an extended state. The rotating mechanism 4 rotates relative to the sliding plate 51, and therefore shelf 1 rotates along with the rotating mechanism 4.

[0032] It should be noted that the orientation of shelf 1 in the initial state is the same as that in the original state. For ease of description, the orientation of shelf 1 in the initial state and the original state is referred to as the first state, and the orientation of shelf 1 in the rotating state is referred to as the second state. When shelf 1 is located outside the refrigerator 10, the shelf 1 switches back and forth between the first state and the second state by rotating the rotating mechanism 4.

[0033] Thus, through the cooperation of the slide rail mechanism 5 and the rotating mechanism 4, the shelf mechanism can switch back and forth between the original state and the initial state, as well as between the initial state and the rotating state. That is, the shelf 1 can switch back and forth between the first state and the second state with the rotation mechanism 4, which makes it convenient for users to pull out the shelf 1 and adjust it to a suitable angle so that users can view and store items in a display manner, avoiding users from searching from the side, thus improving the user experience.

[0034] The aforementioned shelf 1 is used to store items, such as food, cosmetics, and clothing. There may be one, two, or more shelves 1. When there are multiple shelves 1, they can be stacked sequentially along their height. Shelves 1 can be, but are not limited to, shelves 1 in a refrigerator 10 or shelves 1 in a wardrobe.

[0035] However, in some existing refrigerators 10, the shelf 1 is unstable and prone to wobbling after being pulled out and during the pushing and pulling process, resulting in a poor user experience. To solve the above technical problem, please refer to... Figure 4 , Figure 4 yes Figure 3 The diagram shown illustrates the explosion. (Combined with...) Figure 1 and Figure 2In one embodiment, the rotating mechanism 4 includes a fixed part 41, a rotating part 42, and a rotating assembly 43. The fixed part 41 is used to connect with the platform to be mounted. The fixed part 41 can be disconnected from the platform to be mounted. The platform to be mounted can be any plane; for example, the platform to be mounted can be the sliding plate 51 in the slide rail mechanism 5 described above. The sliding plate 51 is used to cause the rotating mechanism 4 to slide along the slide rail mechanism 5. The side of the rotating part 42 opposite to the fixed part 41 is used to connect with the shelf 1. The rotating part 42 can be disconnected from the shelf 1.

[0036] A rotating assembly 43 is disposed between the fixed part 41 and the rotating part 42. The rotating part 42 is rotatably connected to the fixed part 41 via the rotating assembly 43. When the rotating part 42 rotates, the shelf 1 rotates with the rotating part 42 because it is connected to the rotating part 42, thereby driving the shelf 1 to switch back and forth between the first state and the second state. The rotating assembly 43 reduces the friction between the rotating part 42 and the fixed part 41 during rotation, making the rotation of the shelf 1 smoother, reducing the swaying of the shelf 1, and making it easier for the user to adjust the shelf 1 to a suitable angle. In addition, during the rotation of the shelf 1 with the rotating part 42, the rotating assembly 43 can play a certain load-bearing role, which can meet the rotation of heavier shelves 1, thereby improving the feasibility of applying the rotating mechanism 4 to heavier shelves 1.

[0037] The first state described above is the initial state of shelf 1. The initial state is when shelf 1 is free from interference with other related components around it. The second state is the rotating state of shelf 1. For example, when shelf 1 is applied to refrigerator 10, the initial state of shelf 1 is when shelf 1 is pushed or pulled from inside refrigerator 10 to outside. The second state is the rotating state of shelf 1. The rotating state is the state of shelf 1 after it rotates with the rotating part 42. The rotating state can allow shelf 1 to be in an active state or a locked state; this is not limited here. The aforementioned rotating mechanism 4 can also be used in other devices that enable rotation, such as wardrobes, refrigerators 10, snack cabinets, etc. Shelf 1 can also be applied to cabinet structures, etc., without limitation here.

[0038] Therefore, through the cooperation of the rotating part 42, the fixing part 41 and the rotating component 43, the shelf 1 is subjected to more even force and rotates more smoothly after being pulled out and during the pushing and pulling process, reducing the shaking of the shelf 1. At the same time, it can better meet the load-bearing requirements and improve the user experience.

[0039] In one embodiment, please refer to Figures 1 to 4The rotating assembly 43 includes at least one thrust bearing 431. The rotating part 42 is rotatably mounted on the fixed part 41 via at least one thrust bearing 431. The specific arrangement of the thrust bearing 431 is not limited, as long as it enables the rotating part 42 to rotate relative to the fixed part 41. The thrust bearing 431 is disposed between the rotating part 42 and the fixed part 41 to reduce the friction between the rotating part 42 and the fixed part 41 during rotation, facilitating smooth rotation of the shelf 1. In addition, the thrust bearing 431 serves a load-bearing function, capable of supporting the weight of the rotating part 42 and the shelf 1 on it, improving the feasibility of applying the rotating mechanism 4 to the shelf 1; at the same time, it makes the rotation of the rotating mechanism 4 smoother and reduces the swaying of the shelf 1.

[0040] In this embodiment, the rotating assembly 43, through a plurality of thrust bearings 431, not only supports the heavier shelf 1, improving the smoothness of the shelf 1's rotation and reducing the shelf 1's swaying, but also enhances the user experience of rotating the shelf 1. The aforementioned thrust bearings 431 can be provided in one, two, or more forms, and their number can be determined according to the actual situation.

[0041] Specifically, both the surface of the fixed part 41 facing the rotating part 42 and the surface of the rotating part 42 facing the fixed part 41 are provided with thrust bearing grooves 413. The thrust bearing grooves 413 are used to install thrust bearings 431. The thrust bearing 431 is inserted into two adjacent thrust bearing grooves 413 to fix the thrust bearing 431 and prevent it from coming out; at the same time, it improves the smoothness of the rotation of the thrust bearing 431. When there are two, three, or more thrust bearings 431, adjacent thrust bearings 431 are connected in series and can be stacked sequentially along their height direction. Adjacent thrust bearings 431 are detachably connected.

[0042] Additionally, please see Figures 1 to 4 The aforementioned rotating assembly 43 further includes at least one radial bearing 432. A fixed shaft 411 protrudes from the surface of the fixed portion 41 near the rotating portion 42. A thrust bearing groove 413 surrounds the fixed shaft 411. The thrust bearing groove 413 is located on the surface of the fixed portion 41 facing the rotating portion 42 and the surface of the rotating portion 42 facing the fixed portion 41, both surrounding the fixed shaft 411. The radial bearing 432 is sleeved on the fixed shaft 411. The radial bearing 432 is located within the rotating portion 42 and the thrust bearing 431. The radial bearing 432 further reduces the frictional force between the rotating portion 42 and the fixed portion 41 during rotation, facilitating smoother rotation of the shelf 1. The number of radial bearings 432 can be one, two, or more.

[0043] Therefore, the mutual cooperation of the thrust bearing 431 and the radial bearing 432 facilitates the smooth rotation of the shelf 1 and enables it to support heavier shelves, thereby improving the feasibility of applying the rotating mechanism 4 to heavier shelves. Furthermore, the thrust bearing 431 and the radial bearing 432 are standard parts, facilitating installation and purchase.

[0044] In practice, in order to improve the stability of the rotation of the shelf 1, the rotating shaft of the fixed shaft 411 (not shown in the figure), the rotating shaft of the radial bearing 432 (not shown in the figure), the rotating shaft of the thrust bearing 431 (not shown in the figure), and the rotating shaft of the rotating part 42 (not shown in the figure) are coaxially arranged to improve the coaxiality of the rotation mechanism 4, further facilitate the smooth rotation of the shelf 1, and improve the rotation stability of the shelf 1.

[0045] During the process of mounting the radial bearing 432 onto the fixed shaft 411, it is necessary to fix the radial bearing 432 to prevent it from detaching from the fixed shaft 411. In this embodiment, the rotating mechanism 4 may include a pressure plate 44. The pressure plate 44 is detachable from the end face of the fixed shaft 411 away from the fixed part 41. The pressure plate 44 is used to fix the radial bearing 432, thereby limiting the radial bearing 432, preventing it from detaching, and thus improving the rotational stability of the rotating mechanism 4.

[0046] In one embodiment, the rotating mechanism 4 includes a support portion 45. The support portion 45 provides support and can support heavier objects. The specific structure and shape of the support portion 45 are not limited, as long as it can support the shelf 1. The support portion 45 is fixedly connected to the rotating portion 42. Alternatively, the support portion 45 can be detachably connected to the rotating portion 42. One end of the support portion 45 facing away from the rotating portion 42 is used to connect to the shelf 1. This end is detachably connected to the shelf 1. The support portion 45 improves the load-bearing stability of the rotating mechanism 4, facilitating the support of heavier items such as the shelf 1. The support portion 45, together with the thrust bearing 431, further enhances the stability and robustness of the rotating mechanism 4 when applied to the shelf 1, reducing shelf 1 swaying. The support portion 45 can be of any shape, as long as it provides sufficient support. In one specific embodiment, the support portion 45 can have the same shape as the bottom of the shelf 1. In an alternative embodiment, the support portion 45 can be directly used as the bottom of the shelf 1 to reduce the material required for the shelf 1 and lower costs.

[0047] Specifically, the support part 45 is provided with a plurality of support ribs 451. These support ribs 451 provide support, thereby enhancing the stability and robustness of the support part 45. Furthermore, the rotation axes of the fixing part 41, the rotating part 42, and the support part 45 are coaxially arranged, achieving overall coaxiality of the rotating mechanism 4, ensuring the stability of the rotating mechanism 4 in driving the shelf 1, and reducing the swaying of the shelf 1. In addition, the overall coaxiality of the rotating mechanism 4 reduces collisions between the shelf 1 and devices such as the refrigerator 10, thus preventing interference with the rotation of the shelf 1.

[0048] To further improve the uniformity of support of the support portion 45, at least one ring is formed from several support ribs 451. There can be one, two, or more rings. When there are multiple rings, the central axis of the ring is coaxial with the rotation axis of the fixed portion 41, the rotation axis of the rotating portion 42, and the rotation axis of the support portion 45, and the diameter of the ring gradually increases. By sequentially increasing the diameter of the rings, the uniformity of support of the support portion 45 is further improved. In addition, connecting strips 452 are provided on the multiple rings. The connecting strips 452 connect the areas between adjacent rings, further improving the stability and uniformity of the support portion 45. In this embodiment, there are two rings, connected by several connecting strips 452.

[0049] In the aforementioned rotating mechanism 4, the fixed part 41 and the rotating part 42 can have any structure, as long as the rotating part 42 can rotate relative to the fixed part 41. In this embodiment, the fixed part 41 is square, and its size and shape are similar to those of the support part 45; the rotating part 42 is circular, etc. Furthermore, the fixed part 41 can be connected to the platform to be mounted using several screws. The rotating part 42 can be connected to the shelf 1 using several screws. The pressure plate 44 can be connected to the fixed shaft 411 using several screws. In other embodiments, the rotating part 42 can pass through the support part 45 and connect to the shelf 1 using several screws.

[0050] Compared to existing shelves where the weight is mainly concentrated in the central column, making them unstable and prone to wobbling, this application provides a rotating component 43 between the fixed part 41 and the rotating part 42. The rotating part 42 is rotatably connected to the fixed part 41 via the rotating component 43, which makes the shelf 1 more evenly stressed and rotates more smoothly during pulling out and pushing / pulling, thus reducing the wobbling of the shelf 1. At the same time, it can better meet the load-bearing requirements and improve the user experience.

[0051] However, as more and more items are placed on shelf 1, the load on shelf 1 increases. When rotating shelf 1 to the desired angle, the bottom of shelf 1 is prone to colliding with the slide rail mechanism 5 used to mount shelf 1, causing shelf 1 to wobble. In one embodiment, please refer to... Figures 1 to 4A limiting groove 412 and a limiting post 421 are provided between the rotating part 42 and the fixed part 41. The limiting groove 412 and the limiting post 421 cooperate with each other, which not only makes the rotation of the rotating mechanism 4 and its upper shelf 1 more stable, but also limits the rotation angle range of the rotating part 42 and its upper shelf 1.

[0052] Specifically, a limiting groove 412 is provided on the surface of the fixed part 41 near the rotating part 42. A limiting post 421 is provided on the surface of the rotating part 42 near the fixed part 41. The limiting post 421 can slide within the limiting groove 412, such as... Figure 4 As shown. When the rotating part 42 rotates relative to the fixed part 41 via the rotating assembly 43, the limiting groove 412 in the fixed part 41 does not rotate, while the limiting post 421 rotates with the rotating part 42. The limiting groove 412 has a semi-circular arc structure. The opening of the semi-circular arc structure faces the back side of the refrigerator body 101. When the shelf 1 rotates to the required angle, the force exerted by the limiting post 421 on the limiting groove 412 is directed towards the back side of the refrigerator body 101, that is, parallel to the straight line where the sliding track trajectory of the slide rail mechanism 5 is located. Therefore, it avoids the shelf from swaying in the direction of the refrigerator body 101 to both sides.

[0053] Compared to the prior art where the limiting post 421 rotates with the rotating part 42 and the limiting groove 412 moves with the fixing part 41, when the shelf 1 rotates to the required angle, such as 90°, the limiting groove 412 collides with the limiting post 421, generating an impact force perpendicular to the slide rail mechanism 5. Since the shelf 1 is heavy, the impact force in this vertical direction is also large, causing the shelf 1 to shake significantly, and even deforming the slide rail mechanism 5, thus damaging the entire slide rail mechanism 5, in this embodiment, when the shelf 1 rotates to the required angle, the limiting post 421 collides with the limiting groove 412, generating an impact force parallel to the slide rail mechanism 5, which significantly reduces the shaking of the shelf 1 and reduces the impact damage to the slide rail mechanism 5.

[0054] In one embodiment, the limiting groove 412 includes a first limiting end 4121 and a second limiting end 4122. Since the first limiting end 4121 and the second limiting end 4122 are on the same diameter of the rotating part 42, the semi-circular arc mechanism is arranged in a semi-circular arc shape. When the limiting post 421 rotates with the rotating part 42, the direction of the force exerted by the limiting post 421 on the first limiting end 4121 or the second limiting end 4122 is consistent with the direction of movement of the shelf 1.

[0055] Specifically, the diameter of the first limiting end 4121 and the second limiting end 4122 in the rotating part 42 is perpendicular to the straight line of the sliding trajectory of the slide rail mechanism 5. In this way, not only is the rotation angle range of the shelf 1 limited to be perpendicular to the sliding trajectory of the slide rail mechanism 5, but also the direction of the force exerted by the limiting post 421 on the limiting groove 412 is the direction of the guide rail extension.

[0056] In one embodiment, the limiting groove 412 includes a first limiting end 4121 and a second limiting end 4122. The first limiting end 4121 is provided with at least one first buffer member 4123; the second limiting end 4122 is provided with at least one second buffer member (not shown in the figure). The first buffer member 4123 is disposed at the first limiting end 4121. The second buffer member 4124 is disposed at the second limiting end 4122. The first buffer member 4123 and the second buffer member play a buffering role. By limiting the limiting post 421 through the first buffer member 4123 and the second buffer member, the collision between the shelf 1 and its adjacent parts and devices such as the refrigerator 10 due to excessive rotation is reduced; at the same time, the force exerted by the limiting post 421 on the limiting groove 412 is reduced. The aforementioned first buffer member 4123 and the second buffer member can be of any structure, as long as they have a certain buffering effect on the limiting post 421. For example, the buffer member 4123 can be a spring, a spring sheet, foam or rubber, etc., which is not limited here.

[0057] To prevent the limiting groove 412 from affecting the rotation angle range of the shelf 1 due to the presence of the first buffer 4123 and the second buffer, in one embodiment, the arc angle range of the limiting groove 412 is reduced or increased. For example, the ends of the first buffer 4123 and the second buffer facing the limiting groove 412 are on the same diameter of the rotating part 42. In this way, not only is the rotation angle range of the shelf 1 limited to be perpendicular to the sliding trajectory of the slide rail mechanism 5, but the direction of the force exerted by the limiting post 421 on the limiting groove 412 is also made to be in the direction of the guide rail extension.

[0058] In one specific embodiment, the midpoint of the line connecting the first limiting end 4121 and the second limiting end 4122 is the center of the circle, meaning the first limiting end 4121 and the second limiting end 4122 are located at opposite ends of the same diameter of the circle. In this embodiment, the maximum rotation angle of the shelf 1 along the slide rail mechanism 5 to the left and right can be 90°. Of course, the maximum rotation angle of the shelf 1 to the left and right can also be, but is not limited to, 79°, 69°, and 47°, etc., and is not limited here.

[0059] In one embodiment, the locking mechanism 6 may further include at least one mechanical locking component 63. The number of mechanical locking components 63 may be one, two, or more. The aforementioned mechanical locking component 63 is disposed on the fixed portion 41. Simultaneously, the mechanical locking component 63 is located at the outer periphery of the rotating portion 42. A plurality of limiting grooves 422 are formed on the outer periphery of the rotating portion 42, and the mechanical locking component 63 can abut within the limiting grooves 422. The mechanical locking component 63 can also release from the limiting grooves 422. Through the mutual cooperation of the limiting grooves 422 and the mechanical locking component 63, the rotation angle of the rotating portion 42 is limited, thereby reducing the risk of shelf 1 swaying.

[0060] To further ensure that the shelf 1 maintains its stability at different rotation angles, this can be achieved by adjusting the number of limiting grooves 422 and / or the number of mechanical locking components 63. For example, there may be one mechanical locking component 63 and three or more limiting grooves 422. Regardless of the rotation angle of the rotating part 42, the mechanical locking component 63 can be releasably engaged with the corresponding limiting groove 422. Alternatively, there may be two or three mechanical locking components 63 and one limiting groove 422, ensuring that a corresponding mechanical locking component 63 matches the limiting groove 422 regardless of the rotation angle of the rotating part 42. Therefore, the number of mechanical locking components 63 and / or the number of limiting grooves 422 can be determined according to actual conditions and is not limited here.

[0061] As a further example, the mechanical locking assembly 63 can be a single unit. The mechanical locking assembly 63 is disposed on the fixed portion 41 or the sliding plate 51, such as on either side of the fixed portion 41 perpendicular to the direction of movement of the shelf 1. When the shelf 1 rotates to either side of the fixed portion 41 perpendicular to the direction of movement of the shelf 1, the mechanical locking assembly 63 restricts the shelf 1, locking it and preventing it from wobbling.

[0062] There can be two mechanical locking components 63. One mechanical locking component 63 is provided on the fixed part 41 or the sliding plate 51 along the moving direction of the shelf 1, and the other mechanical locking component 63 is provided on either side of the fixed part 41 perpendicular to the moving direction of the shelf 1. That is, the shelf 1 can be limited by the mechanical locking components 63 whether it is in the initial state or in the rotating state.

[0063] There can be three mechanical locking components 63. For example, one mechanical locking component 63 is positioned on the fixed part 41 along the direction of movement of the shelf 1. The other two mechanical locking components 63 are symmetrically positioned on the fixed part 41 perpendicular to the direction of movement of the shelf 1. That is, the shelf 1 can be restrained in both its initial and rotating states. The number and position of the aforementioned mechanical locking components 63 can be determined according to actual circumstances and are not limited here.

[0064] In one embodiment, the limiting groove 422 includes a first sub-groove 4221 and a second sub-groove 4222. When the shelf is in the first state, the mechanical locking component 63 abuts against the first sub-groove 4221. Through the interaction of the mechanical locking component 63 and the first sub-groove 4221, the shelf 1 is mechanically locked in both the original state and the first state, thus preventing the shelf 1 from swaying during pushing and pulling. When the shelf is in the second state, the mechanical locking component 63 abuts against the second sub-groove 4222. Through the interaction of the mechanical locking component 63 and the second sub-groove 4222, the shelf 1 is mechanically locked after rotation. With the first sub-groove 4221 and the second sub-groove 4222 respectively cooperating with the mechanical locking component 63, the shelf 1 is locked regardless of whether it is in the first state or the second state, thereby reducing the swaying of the shelf 1. The number of the first sub-groove 4221 and the number of the second sub-groove 4222 can be determined according to actual conditions and is not limited here.

[0065] Specifically, there are two second sub-grooves 4222. The two second sub-grooves 4222 are on the same diameter of the rotating part. When the shelf 1 rotates to the left or right along the direction of movement of the shelf 1, the shelf 1 can be locked, reducing the shaking of the shelf 1 and making it easier for users to store and retrieve items.

[0066] Furthermore, the diameter of the first sub-groove 4221 is perpendicular to the diameter of the two second sub-grooves 4222. This method limits the rotation range of the shelf 1. For example, when the shelf 1 rotates to the left or right along its direction of movement, the angle is 90°.

[0067] Please see Figure 5 , Figure 5 This is a structural schematic diagram of the mechanical locking component in the locking mechanism of this application. Specifically, in conjunction with... Figure 3 and Figure 4 The mechanical locking assembly 63 includes a limiting wheel 631, an elastic limiting member 632, and a limiting cover plate 633. The elastic limiting member 632 has a certain elasticity. The elastic limiting member 632 is located inside the limiting cover plate 633. The limiting wheel 631 is disposed at one end of the limiting cover plate 633 near the rotating part 42. The limiting wheel 631 abuts against the limiting groove 422 of the rotating part 42, thereby limiting the rotating part 42. When the rotating part 42 is rotated by an external force at a certain angle, the elastic limiting member 632 is released from the limiting groove 422 in the rotating part 42.

[0068] Furthermore, the elastic limiting member 632 includes a limiting rod 6321, a limiting head 6322, and a second elastic member 6323. The limiting rod 6321, the limiting head 6322, and the second elastic member 6323 are all disposed within the limiting cover plate 633. The limiting rod 6321 and the limiting head 6322 are fixedly connected. The second elastic member 6323 is sleeved on the limiting rod 6321, driving the limiting head 6322 to releasably push the limiting wheel 631.

[0069] In practice, the mechanical locking assembly 63 cannot achieve forced locking. As the shelf 1 becomes increasingly heavy and involves a considerable pushing and pulling distance rather than a small range of movement, the shelf 1 may sway left and right along its direction of movement during the pushing and pulling process. The mechanical locking assembly 63 cannot ensure the linear movement of the shelf 1, and there is even a risk that it may disengage from the locking position. Once the mechanical locking assembly 63 disengages from the locking position, the shelf will rub against and collide with the side wall of the refrigerator body 101.

[0070] In one embodiment, the rotating mechanism 4 is mounted on the mounting platform fixing plate. The rotating mechanism 4 is used to drive the shelf 1 to rotate around the rotation axis of the rotating mechanism 4. The mounting platform fixing plate can be the sliding plate 51 in the slide rail mechanism 5, and is not limited here. The locking mechanism 6 includes at least one electric locking component 62. The number of electric locking components 62 can be one, two, or more. The electric locking component 62 is used to electrically lock the rotation of the rotating part 42. For example, if the electric locking component 62 is used to electrically lock the rotating part 42, the shelf 1 is in a forced locked state, ensuring that when the shelf 1 moves in a straight line along the moving direction of the shelf 1, friction and collision between the shelf 1 and the side wall of the refrigerator 10 can be avoided. Alternatively, when the electric locking component 62 releases the locking relationship with the rotating part 42, the user can push the shelf 1 to release the connection between the mechanical locking component 63 and the rotating part 42, thereby realizing the free rotation of the shelf 1. Therefore, the electric locking component 62 can limit the stability of the shelf 1 and the automatic rotation of the shelf 1, improve the user experience, and prevent the shelf 1 from rubbing and colliding with the side wall of the refrigerator 10.

[0071] Specifically, the electric locking assembly 62 includes a drive rod 621 and a drive member 622. The drive rod 621 is connected to the drive shaft of the drive member 622, and the drive shaft of the drive member 622 acts on the drive rod 621. The drive rod 621 is inserted into the rotating part 42, electrically limiting the rotation of the rotating part 42. To achieve automatic limiting of the electric locking assembly 62, this embodiment can use electromagnetic induction. For example, a sensing component (not shown in the figure) is provided in the shelf mechanism, and the sensing component is signal-connected to the drive member 622. The drive member 622 drives the drive rod 621 to engage or disengage with the rotating part 42 according to the rotation signal sensed by the sensing component.

[0072] When the shelf mechanism moves from its initial state to its first state, the drive rod 621 is inserted into the rotating part 42, restricting the rotation of the rotating part 42. When the shelf 1 moves from the first state to the second state, the sensing component transmits a signal to the drive member 622, which drives the drive rod 621 to release the locking connection between the drive rod 621 and the rotating part 42. When the shelf 1 switches from the second state to the first state, the sensing component transmits a signal to the drive member 622, which drives the drive rod 621 to insert into the rotating part 42 to ensure the stability of the shelf 1, prevent it from shaking, and thus reduce the risk of damage to the inner wall of the refrigerator 10. The drive member 622 is installed and removed from the sliding plate 51. The drive rod 621 can be detachably inserted into the rotating part 42 via the drive member 622, realizing the automatic unlocking of the rotating part 42. Optionally, the drive member 622 is a drive motor.

[0073] Specifically, the outer periphery of the rotating part 42 has several limiting grooves 422. The drive rod 621 can be inserted into the limiting grooves 422 via the drive member 622, and the drive rod 621 can be released from the limiting grooves 422 via the drive member 622. By directly engaging the drive rod 621 with the limiting grooves 422, the stability of the electric locking between the electric locking assembly 62 and the rotating part 42 is improved, further preventing friction and collision between the shelf 1 and the side wall of the refrigerator 10.

[0074] In one embodiment, the locking mechanism 6 includes an electric locking component 62 and a mechanical locking component 63, which are located at both ends of the rotating mechanism 4. By simultaneously providing the electric locking component 62 and the mechanical locking component 63, the stability of the shelf 1 can be improved, reducing the collision between the shelf 1 and the side wall of the refrigerator 10 during pushing and pulling. Furthermore, the specific positions of the electric locking component 62 and the mechanical locking component 63 prevent interference between them during operation.

[0075] In one embodiment, the limiting groove 422 includes a first sub-groove 4221 and a second sub-groove 4222, and also includes a third sub-groove (not shown in the figure). When the shelf 1 is in the first state, the drive rod 621 is inserted into the third sub-groove. The rotating part 42 is automatically locked and unlocked by the electric locking assembly 62, thereby automatically controlling the shelf 1.

[0076] Specifically, the third sub-groove and the first sub-groove 4221 are located on the same diameter of the rotating part 42, so that the third sub-groove can be inserted into the electric locking assembly 62 and the first sub-groove 4221 can be inserted into the mechanical locking assembly 63, thereby realizing the joint insertion and cooperation of the electric locking assembly 62 and the mechanical locking assembly 63. A driving block 623 is provided at the end of the driving rod 621, and the driving block 623 is inserted into the third sub-groove. To improve the stability of the driving block 623 inserted into the third sub-groove, the shape of the driving block 623 can be the same as the shape of the third sub-groove, and is not limited here.

[0077] In practice, when the shelf 1 is in a rotating state, the electric locking component 62 can also be inserted into the rotating part 42 to facilitate the user's storage of items and reduce the risk of the shelf 1 rotating due to accidental contact with the mechanical locking component 63 during storage. The shape of the third sub-groove can be the same as that of the first sub-groove 4221 and the second sub-groove 4222 to facilitate the insertion of the electric locking component 62.

[0078] Compared to existing technologies, the rotating mechanism 4 in this application drives the shelf 1 to rotate around its rotation axis, allowing users to view and store items. The locking mechanism 6 includes an electric locking assembly 62, which comprises a drive rod 621 and a drive member 622. The drive rod 621 is connected to the drive shaft of the drive member 622, and the drive rod 621 can be releasably inserted into the rotating mechanism 4 via the drive member 622. Through this method, the rotating mechanism 4 can be forcibly locked or unlocked, ensuring that the shelf 1 moves linearly along the shelf's moving direction and preventing friction and collision between the shelf 1 and the refrigerator body 101.

[0079] Please see Figure 6 , Figure 6 This is a structural schematic diagram of the limit component in the locking mechanism of this application. (Combined with...) Figures 1 to 4 In one embodiment, the locking mechanism 6 includes at least one limiting component 61. The limiting component 61 is hinged to the sliding plate 51, meaning that the limiting component 61 can rotate around the sliding plate 51 by a certain angle. The limiting component 61 includes a first limiting portion 611 and a second limiting portion 612. The first limiting portion 611 and the second limiting portion 612 are connected. The first limiting portion 611 is disposed on the side of the sliding plate 51 facing the fixed portion 41. The second limiting portion 612 is disposed on the side of the sliding plate 51 away from the fixed portion 41.

[0080] During the transition of the shelf mechanism from its original state to its initial state, since the rotating mechanism 4 does not rotate relative to the sliding plate 51, the first limiting part 611 elastically abuts against the shelf 1 to limit the shelf 1, prevent the shelf 1 from rotating, and reduce the shelf 1's swaying, thus achieving the stability of the shelf 1. That is, the shelf 1 is maintained in the first state. At the same time, during the elastic abutment between the first limiting part 611 and the shelf 1, the first limiting part 611 drives the second limiting part 612, so that there is no abutment relationship between the second limiting part 612 and the guide rail fixing plate 52, and they disengage from each other. The sliding plate 51 can slide relative to the guide rail fixing plate 52.

[0081] When the shelf 1 is subjected to external force, during the process of the shelf 1 changing from the first state to the second state, the elastic contact between the first limiting part 611 and the shelf 1 is released, the first limiting part 611 returns to its original state and drives the second limiting part 612 to tilt up, so that the second limiting part 612 is locked in the guide rail fixing plate 52, thereby creating a fixed relationship between the sliding plate 51 and the guide rail fixing plate 52, and avoiding relative sliding between the sliding plate 51 and the guide rail fixing plate 52.

[0082] Furthermore, the relative sliding between the sliding plate 51 and the guide rail fixing plate 52 is limited by the limiting component 61, thereby improving the stability of the shelf 1 and the smoothness of its rotation. The number of limiting components 61 can be one, two, or more, depending on the actual situation.

[0083] The locking mechanism 6 includes at least one limiting component 61. The limiting component 61 is hinged to the sliding plate 51, meaning that the limiting component 61 can rotate around the sliding plate 51 by a certain angle. The limiting component 61 includes a first limiting part 611 and a second limiting part 612. The first limiting part 611 and the second limiting part 612 are connected to each other. The first limiting part 611 is disposed on the side of the sliding plate 51 facing the fixed part 41. The second limiting part 612 is disposed on the side of the sliding plate 51 away from the fixed part 41.

[0084] During the transition of shelf 1 from its original state to its initial state, since the rotating mechanism 4 does not rotate relative to the sliding plate 51, the first limiting part 611 elastically abuts against shelf 1 to limit shelf 1, prevent shelf 1 from rotating and reduce shelf 1 swaying, thus achieving the stability of shelf 1. That is, shelf 1 is maintained in the first state. At the same time, during the elastic abutment of the first limiting part 611 against shelf 1, the first limiting part 611 drives the second limiting part 612 to disengage from the guide rail fixing plate 52, allowing the sliding plate 51 to slide relative to the guide rail fixing plate 52.

[0085] When the shelf 1 is subjected to an external force, during the transition from the first state to the second state, the elastic contact between the first limiting part 611 and the shelf 1 is released, preventing the first limiting part 611 from interfering with the rotation of the shelf 1 and improving the smoothness of the rotation of the shelf 1. At the same time, the first limiting part 611 drives the second limiting part 612 to engage with the guide rail fixing plate 52, thereby establishing a fixed relationship between the sliding plate 51 and the guide rail fixing plate 52 and preventing relative sliding between the sliding plate 51 and the guide rail fixing plate 52.

[0086] Therefore, through the cooperation of the slide rail mechanism 5 and the rotating mechanism 4, the shelf 1 can switch back and forth between the original state and the initial state, as well as between the initial state and the rotating state, making it convenient for users to pull out the shelf 1 and adjust it to a suitable angle for displaying and storing items. Furthermore, the limiting component 61 improves the smoothness of the rotation of the shelf 1, while limiting the relative sliding between the sliding plate 51 and the guide rail fixing plate 52.

[0087] The aforementioned slide rail mechanism 5, rotating mechanism 4, and locking mechanism 6 can be of any structure, as long as they can achieve sliding, rotating, and limiting functions; their specific structures are not limited. Additionally, the fixing part 41 can be of any structure and is not limited here. Furthermore, the number of limiting components 61 can be one, two, or more, depending on the actual situation.

[0088] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 6 Specifically, the shelf 1 includes a support platform 13. The support platform 13 is detachably mounted to the side of the shelf 1 near the rotating mechanism 4. Of course, the support platform 13 can be fixed or integrally formed into the shelf 1. The first limiting part 611 includes a limiting bridge 6111. The support platform 13 and the limiting bridge 6111 cooperate with each other through the limiting protrusion 6113 and the limiting recess 131 to realize the unlocking and locking of the shelf 1 and the slide rail mechanism 5.

[0089] In one specific embodiment, such as Figure 6As shown, a limiting recess 131 is provided on the side of the support platform 13 near the limiting bridge 6111. A limiting protrusion 6113 is provided on the side of the limiting bridge 6111 near the support platform 13. The limiting protrusion 6113 can be inserted into the limiting recess 131. The vertical cross-sectional shape of the limiting protrusion 6113 can be semi-circular. The vertical cross-sectional shape of the limiting recess 131 can also be semi-circular. When the shelf 1 and the limiting bridge 6111 come into contact, the limiting bridge 6111 presses down. During the rotation of the shelf 1, the limiting protrusion 6113 on the limiting bridge 6111 gradually slides into the limiting recess 131, thereby locking the shelf 1 and the slide rail mechanism 5. When the shelf 1 and the limiting bridge 6111 disengage, the limiting protrusion on the limiting bridge 6111 gradually disengages from the limiting recess 131, thereby unlocking the shelf 1 and the slide rail mechanism 5.

[0090] In an alternative embodiment, a limiting protrusion 6113 is provided on the side of the support platform 13 near the limiting bridge 6111. A limiting recess 131 is provided on the side of the limiting bridge 6111 near the support platform 13. The limiting protrusion 6113 can be inserted into the limiting recess 131, such as... Figure 6 As shown.

[0091] Please continue reading. Figure 2 , Figure 3 , Figure 4 as well as Figure 6 In one embodiment, the first limiting part 611 includes a first elastic member 6112, one end of which abuts against the sliding plate 51, and the other end abuts against the limiting bridge 6111. The second limiting part 612 includes a limiting leg 6121, which is hinged to the sliding plate 51, and the limiting leg 6121 and the limiting bridge 6111 are connected. The limiting leg 6121 can be released from the guide rail fixing plate 52. When the shelf 1 is pulled out without rotation, the limiting bridge 6111 in the first limiting part 611 abuts against the support platform 13, the first elastic member 6112 is compressed, and there is no abutment relationship between the limiting leg 6121 and the slide rail mechanism 5, that is, the slide rail mechanism 5 can slide freely, and the user can smoothly complete the pulling and pushing actions of the shelf 1.

[0092] When shelf 1 is pulled out and the user rotates shelf 1, support platform 13 rotates with shelf 1. Then, support platform 13 disengages from limiting bridge 6111 and releases its contact. First elastic element 6112 returns to its original state. Limiting bridge 6111 acts on limiting leg 6121, which abuts against guide rail fixing plate 52. This limits the relative sliding between sliding plate 51 and guide rail fixing plate 52, thus preventing shelf 1 from sliding towards refrigerator body 101 while rotating. This ensures smooth rotation of shelf 1 and prevents shelf 1 from being pushed by external force and colliding with refrigerator body 101 while rotating. The first limiting part 611 and the second limiting part 612 can also be any structure, and their specific structure is not limited. First elastic element 6112 can be a spring. When the user rotates the shelf 1 back to its initial state after storing or retrieving items, the support platform 13 comes into contact with the limiting bridge 6111 again, the first elastic element 6112 is compressed, the limiting bridge 6111 acts on the limiting leg 6121, the limiting leg 6121 rotates and then releases the contact relationship with the guide rail fixing plate 52, and the user can push the shelf 1 back to its original state smoothly.

[0093] Specifically, the sliding plate 51 is detachably mounted with a limiting plate 53. The limiting plate 53 has a limiting hole 531, which passes through the connection between the limiting bridge 6111 and the limiting leg 6121. The first limiting part 611 is located on the side of the limiting plate 53 closer to the fixing part 41. The second limiting part 612 is located on the side of the limiting plate 53 away from the fixing part 41. The limiting leg 6121 is hinged to the limiting plate 53. There are two limiting legs 6121.

[0094] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 2 The structural diagram of A shown below; Figure 8 This is a partial schematic diagram of a second embodiment of the refrigerator of this application. (In conjunction with...) Figure 2 , Figure 4 as well as Figure 6 To increase the contact area between the limiting legs 6121 and the slide rail mechanism 5, the two limiting legs 6121 are bent inwards relative to each other. Alternatively, a corresponding stop (not shown in the figure) can be provided on the slide rail mechanism 5, such as on the guide rail fixing plate 52. The stop (not shown in the figure) contacts the contact surface of the limiting legs 6121, further increasing the contact area between the limiting legs 6121 and the slide rail mechanism 5, making the limiting assembly 61 more stable and secure in its positioning.

[0095] The aforementioned first limiting part 611 also includes an elastic post 6114. A hollow cylindrical tube 532 (not shown in the figure) protrudes from one end of the limiting plate 53 away from the fixing part 41. The first elastic member 6112 passes through the cylindrical tube 532 of the elastic post 6114. The end of the elastic post 6114 facing the limiting bridge 6111 is fixedly connected to the limiting bridge 6111.

[0096] As in one specific embodiment, such as Figure 7 As shown, the guide rail fixing plate 52 has a first stop portion 521 protruding from its end facing the limiting assembly 61. The first stop portion 521 is releasably abutted against the limiting leg 6121. The first stop portion 521 includes two stop plates, each corresponding to the limiting leg 6121. In another alternative embodiment, such as... Figure 8 As shown, the guide rail fixing plate 52 has a second stop 522 protruding from its end facing the limiting assembly 61. The second stop 522 is releasably abutted against the limiting leg 6121. The second stop 522 is bent toward the sliding plate 51. The end of the second stop 522 away from the guide rail fixing plate 52 is releasably abutted against the limiting leg 6121.

[0097] The locking mechanism 6 described above can be at least one of the following: a limiting component 61, an electric locking component 62, and a mechanical locking component 63. For example, the locking mechanism 6 may include a limiting component 61, an electric locking component 62, an electric locking component 62, and a mechanical locking component 63, or simultaneously include a limiting component 61, an electric locking component 62, and a mechanical locking component 63. The locking mechanism 6 can be configured according to actual conditions, and is not limited here.

[0098] In one embodiment, the shelf 1 includes a door 11 and a storage area 12, which can be integrally formed. Alternatively, the door 11 and the storage area 12 can be detachably connected. When the shelf 1 is rotated, the door 11 and the storage area 12 rotate simultaneously. The storage area 12 is used to store food, cosmetics, clothing, etc. The storage area 12 can be composed of multiple drawers. When there are multiple drawers, they can be stacked sequentially along their height.
