Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a tray mechanism and a storage device. Background Art

[0002] At present, in order to improve the space utilization rate in the refrigerator, a tray structure that can be raised and lowered is usually provided in the refrigerator, so that items of different heights can be placed on the tray structure. In the related art, multiple spring structures are provided in the tray structure to ensure resetting. During installation, the presence of multiple spring structures will increase the difficulty of installation and reduce the installation efficiency. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] In view of this, an embodiment of a first aspect of the present invention provides a tray mechanism.

[0005] An embodiment of a second aspect of the present utility model provides a storage device.

[0006] In order to achieve the above-mentioned objectives, an embodiment of the first aspect of the utility model provides a tray mechanism, including: a base structure; a control rod, which is slidably connected to the base structure; a slider structure, which is slidably connected to the base structure; a connecting rod structure, which is rotatably connected to the base structure, one end of the connecting rod structure is movably connected to the control rod, and the other end is movably connected to the slider structure; a reset member, which is arranged on the base structure, and one end of the reset member is connected to the control rod, and the reset member is in a compressed state.

[0007] According to the tray mechanism proposed by the utility model, it mainly includes a base structure, a control rod, a slider structure, a connecting rod structure and a reset member. The user can adjust the height of the tray by simply pushing and pulling the control rod. For example, when the control rod is pulled, the connecting rod structure rotates, pushing the slider structure to slide along the slide groove of the base structure, and the tray can be moved up and down at this time, so as to realize the lifting and lowering of the tray. Specifically, the base structure serves as the main body and supporting base of the tray mechanism, and it provides a stable platform for installing all other components, including the control rod, the slider structure and the connecting rod structure. The base structure can be designed with a slide groove and a rotating shaft so that other components can slide and rotate correctly. The control rod can move along a preset path by slidingly connecting with the base structure. The control rod is usually located in a position that is easy for the user to access, so that the user can limit and unlock the position of the tray by pushing and pulling, thereby operating the lifting and lowering of the tray. The slider structure is slidably connected to the base structure, usually located on both sides of the tray, and mainly plays the role of limiting and unlocking. After the slider slides to the unlocking position, it can guide the tray to move in the vertical direction, so as to realize the lifting and lowering function. The design of the slider structure ensures the smooth rise and fall of the pallet, while also taking on part of the load-bearing role.

[0008] It should be emphasized that the structure used to connect the control rod and the slider structure in the present application is a rigid connecting rod structure. By movably connecting one end of the connecting rod structure to the control rod and the other end to the slider structure, and rotatably connecting the middle part to the base structure, the connecting rod can be allowed to transmit force between the control rod and the slider structure, converting the linear motion of the control rod into the linear motion of the slider. The rotation of the connecting rod structure allows the entire mechanism to maintain synchronization and coordination during lifting and lowering. In addition, the installation efficiency can be greatly improved by the connecting rod structure.

[0009] It should be added that the reset member of the present application can be a spring assembly, one end of which is connected to the control rod and is in a compressed state. The main function of the reset member is to provide a return force so that the control rod and thus the entire tray mechanism can automatically return to the original position without the action of external force. In this way, after the user adjusts the position of the tray, it can be ensured that the tray will not drop when the control rod is released and remain at the set height position. The reset member ensures the convenience and safety of operation and keeps the tray stable when no external force is applied. This mechanism makes the position adjustment of the tray simple and intuitive, and is suitable for refrigerators, cabinets or other storage facilities that require frequent adjustment of the internal space.

[0010] In some technical solutions, optionally, the connecting rod structure includes a first body and a second body at a first angle, the first body is provided with a second slot hole, the second body is provided with a third slot hole, and the first body and the second body are not parallel.

[0011] In this technical solution, the connecting rod structure is composed of two non-parallel bodies, namely a first body and a second body, so that the connecting rod structure can move and rotate at different angles. The first body and the second body are not parallel, so that a specific angle is formed between the two. The existence of this angle allows the connecting rod to move in a non-vertical manner during movement. This non-vertical movement can provide more flexibility and diversity for the operation of the mechanism. A second slot is provided on the first body, and a third slot is provided on the second body. The existence of these slots allows the connecting rod structure to be connected to other components and perform relative movement. The position and angle of the slots can affect the movement trajectory and range of the connecting rod, so that the mechanism can achieve more diverse movement modes.

[0012] In general, the design of the connecting rod structure allows the tray mechanism to move at different angles and directions, and can achieve more diverse operating methods. The flexibility and diversity of this design can bring more choices and possibilities to the design of the lifting tray mechanism to meet the use requirements in different scenarios.

[0013] In some technical solutions, optionally, the control rod moves along the first direction, and under the action of the connecting rod structure, the slider structure moves toward the inner side of the base structure to unlock the position.

[0014] In this technical solution, the movement of the control rod is the starting action of the entire unlocking and lifting process. Specifically, when the user pushes and pulls the control rod, it moves along a first direction (usually a front-to-back direction). This movement is achieved by the user's direct manual operation, or by other mechanical means (such as buttons, levers, etc.). One end of the connecting rod structure is movably connected to the control rod, and the other end is movably connected to the slider structure. The movement of the control rod causes the connecting rod structure to rotate around its rotation point (which may be a pivot or a support shaft). Since the first body and the second body are not parallel, this rotation of the connecting rod causes the slider structure to move along a specific trajectory.

[0015] The slider structure moves inwardly toward the base structure as the link structure rotates. This inward movement is performed along a slide groove or guide rail on the base structure, and this movement is to unlock the card position. The card position is usually a mechanical locking mechanism used to keep the pallet stationary when it reaches a specific position.

[0016] As the slide mechanism moves inward, it interacts with the detent mechanism, releasing the latch. This typically involves the slide moving out of a groove or protrusion that holds the tray in place.

[0017] Once the detents are unlocked, the tray can be raised or lowered freely. The user can continue to operate the lever to adjust the tray to the desired height, or the tray may automatically rise, depending on the design of the mechanism and the effects of gravity.

[0018] Users can unlock and adjust the position of the tray through simple operations, making it easy and convenient to access items or adjust storage space.

[0019] In some technical solutions, optionally, it includes: an installation groove, which is arranged on the base structure; a first sliding groove, which is arranged on the base structure; the control rod includes a rod body and a sliding part connected to the rod body, the rod body is arranged in the installation groove, and the sliding part slides in cooperation with the first sliding groove.

[0020] In this technical solution, a mounting groove is provided on the base structure for mounting and fixing the rod body of the control rod. This groove can ensure that the control rod is correctly positioned and fixed on the base structure so that it can be moved and operated stably. A first slide groove is also provided on the base structure for the sliding part of the control rod to cooperate with. The function of this slide groove is to guide the sliding of the control rod so that the control rod can move along a predetermined path. The design and position of the first slide groove will directly affect the movement trajectory and range of the control rod. The control rod consists of a rod body and a sliding part connected to the rod body. The rod body is provided in the mounting groove to ensure that the control rod is correctly mounted on the base structure. The sliding part slides with the first slide groove so that the control rod can slide freely in the slide groove, thereby realizing the corresponding operating function.

[0021] By moving the control rod, the sliding part slides in the first slide groove, so that the mechanism can be controlled and operated. The existence of the mounting groove ensures the stable installation of the control rod, while the design and position of the first slide groove affect the movement trajectory of the control rod. The flexibility and stability of this design can provide reliable operating performance for the lifting tray mechanism.

[0022] In some technical solutions, optionally, it also includes: a second slide groove, which is arranged on the base structure, and the slider structure cooperates with the second slide groove to achieve a sliding connection between the slider structure and the base structure.

[0023] In this technical solution, the second slide groove is used to provide a sliding connection for the slider structure, so that it can slide freely on the base structure. It can ensure that the slider structure can slide smoothly along the second slide groove, thereby achieving a reliable connection with the base structure. This sliding connection is to enable the slider structure to achieve corresponding movement in the lifting tray mechanism under the action of the control rod.

[0024] The design of the second slide groove provides a stable sliding connection for the slider structure, so that the slider can slide smoothly on the base structure, thereby realizing the movement function of the lifting tray mechanism.

[0025] In some technical solutions, optionally, a first column is provided on the base structure, a first axial hole matching with the first column is provided on the connecting rod structure, and the connecting rod structure realizes a rotational connection with the base structure around the axis of the first column.

[0026] In this technical solution, the first column is a component of the base structure, and the connecting rod structure is provided with a first axial hole that cooperates with the first column, so that it can be rotatably connected with the base structure. The connecting rod structure can cooperate with the first column through the first axial hole, thereby realizing rotation around the axis of the first column.

[0027] This design allows the connecting rod structure to coordinate with the base structure when rotating and transmit appropriate power and movement. This rotating connection allows the connecting rod structure to move at different angles and directions to meet the operating requirements of the lifting tray mechanism.

[0028] In some technical solutions, optionally, it also includes: a second column, which is arranged on the slider structure; a second slot corresponding to the second column is arranged on the connecting rod structure, and the second column is located in the second slot.

[0029] In this technical solution, a second column is provided on the slider structure, and a second slot corresponding to the second column is provided on the connecting rod structure. This design enables the slider structure to achieve relative rotation and sliding connection with the connecting rod structure. The second column is located in the second slot, ensuring that the slider structure can stay firmly at the specified position.

[0030] When the slider structure moves along the first slide slot, the cooperation between the second column and the second slotted hole enables the slider structure to rotate and slide accordingly under the drive of the connecting rod structure, thereby unlocking the position and realizing the lifting and lowering of the tray. This design increases the stability and reliability of the mechanism and improves the operating performance.

[0031] In some technical solutions, optionally, it also includes: a third column, which is arranged on the control rod; a third slot corresponding to the third column is arranged on the connecting rod structure, and the third column is located in the third slot.

[0032] In this technical solution, a third column is provided on the control rod, and a third slot corresponding to the third column is provided on the connecting rod structure. This design enables the control rod and the connecting rod structure to achieve relative rotation and sliding connection. The third column is located in the third slot, ensuring that the control rod can stay firmly at the specified position. When the control rod moves along the first direction, the connecting rod structure will be driven by the control rod and rotate and move in the third slot with the third column, thereby driving the slider structure to move along the first slide slot, unlocking the position and realizing the lifting and lowering of the tray.

[0033] This design increases the stability and reliability of the mechanism operation and improves the operating performance. At the same time, the cooperation between the third column and the third slot can also play a limiting role, ensuring that the control rod will not exceed the preset range during the movement, thereby ensuring the normal operation of the mechanism.

[0034] In some technical solutions, optionally, it also includes: a fixed seat, which is arranged on the base structure; a guide shaft, which is arranged in the control rod, a reset member is sleeved outside the guide shaft, and one end of the reset member is connected to the fixed seat.

[0035] In this technical solution, the fixing seat is arranged on the base structure, the guide shaft is arranged in the control rod, the reset member is sleeved outside the guide shaft, and one end of the reset member is connected to the fixing seat, and the fixing seat provides a fixed installation position for the reset member to ensure that the reset member can work stably and will not be displaced during the operation of the mechanism. The guide shaft is located in the control rod, and when the control rod moves in the first direction, the guide shaft moves with the control rod, thereby guiding the reset member to move along the axis of the guide shaft.

[0036] The reset member is sleeved outside the guide shaft, and one end of the reset member is connected to the fixed seat. When the control rod is pulled, the reset member is compressed and stores energy. When the control rod is released, the reset member releases energy and pushes the control rod back to its original position.

[0037] The restoring force of the reset member helps maintain the stability of the pallet. When the pallet is in the raised or lowered position, the reset member provides a reverse force to prevent the pallet from accidentally moving due to external forces or gravity. Of course, the restoring force of the reset member can prevent the control rod from moving uncontrollably and quickly after being released, thereby improving the safety of operation.

[0038] The above structure enables the mechanism to maintain stability and safety during operation, and can automatically reset after the control rod is released, thereby improving the service life and reliability of the mechanism.

[0039] An embodiment of the second aspect of the utility model provides a storage device, including: a lifting slide rail, on which is provided at least one locking position; any tray mechanism in the above-mentioned first aspect, wherein the slider structure of the tray mechanism is locked by the locking position, and when the control rod moves along the first direction, the slider structure is unlocked.

[0040] According to the storage device proposed by the utility model, the lifting rail provides a stable support and guide for the tray mechanism, ensuring that the tray mechanism can be lifted and moved smoothly. At least one latch is provided on the lifting rail, and when the slider structure of the tray mechanism is engaged with the latch, the tray mechanism is locked in a specified position to prevent accidental movement. When the control rod moves along the first direction, the slider structure of the tray mechanism is unlocked, thereby releasing the tray mechanism so that it can be lifted and moved freely.

[0041] The design of this storage device allows users to easily adjust the position of the tray mechanism through a control lever, thereby flexibly adjusting the storage space to meet different storage needs. In addition, through this storage device, users can classify and store items on different trays and adjust the position of the trays as needed, thereby improving storage efficiency and convenience.

[0042] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0055] Refer to the following Figures 1 to 7 Some embodiments according to the present invention are described.

[0056] like Figure 1 and Figure 2 As shown, a tray mechanism 100 proposed in this embodiment mainly includes a base structure 102, a control rod 104, a slider structure 106, a connecting rod structure 108 and a reset member 110. The user can adjust the height of the tray by simply pushing and pulling the control rod 104. For example, when the control rod 104 is pulled, the connecting rod structure 108 rotates, pushing the slider structure 106 to slide along the slide groove of the base structure 102, and the tray can be moved up and down at this time, thereby realizing the lifting and lowering of the tray. Specifically, the base structure 102 serves as the main body and supporting base of the tray mechanism 100, and it provides a stable platform for installing all other components, including the control rod 104, the slider structure 106 and the connecting rod structure 108. The base structure 102 can be designed with a slide groove and a rotating shaft so that other components can slide and rotate correctly. The control rod 104 can move along a preset path by slidingly connecting with the base structure 102. The control rod 104 is usually located at a position that is easy for the user to access, so that the user can limit and unlock the position of the tray by pushing and pulling, thereby operating the lifting and lowering of the tray. The slider structure 106 is slidably connected to the base structure 102 and is usually located on both sides of the tray. It mainly plays the role of limiting and unlocking. After the slider slides to the unlocking position, it can guide the tray to move in the vertical direction, thereby realizing the lifting function. The design of the slider structure 106 ensures that the tray rises and falls smoothly, and also bears part of the load-bearing function.

[0057] It should be emphasized that the structure used to connect the control rod 104 and the slider structure 106 in the present application is a rigid connecting rod structure 108. By movably connecting one end of the connecting rod structure 108 to the control rod 104 and the other end to the slider structure 106, and rotatably connecting the middle part to the base structure 102, the connecting rod can be allowed to transmit force between the control rod 104 and the slider structure 106, and convert the linear motion of the control rod 104 into the linear motion of the slider. The rotation of the connecting rod structure 108 allows the entire mechanism to maintain synchronization and coordination during lifting. In addition, the installation efficiency can be greatly improved by the connecting rod structure 108.

[0058] It should be added that the reset member 110 of the present application can be a spring assembly, one end of which is connected to the control rod 104 and is in a compressed state. The main function of the reset member 110 is to provide a return force so that the control rod 104 and therefore the entire tray mechanism 100 can automatically return to the original position without the action of external force. In this way, after the user adjusts the position of the tray, it can be ensured that the tray will not drop when the control rod 104 is released, and remain at the set height position. The reset member 110 ensures the convenience and safety of operation, so that the tray remains stable when there is no external force. This mechanism makes the position adjustment of the tray simple and intuitive, and is suitable for refrigerators, cabinets or other storage facilities that require frequent adjustment of the internal space.

[0059] In some embodiments, optionally, the connecting rod structure 108 is composed of two non-parallel bodies, namely a first body 1082 and a second body 1084, so that the connecting rod structure 108 can move and rotate at different angles. The first body 1082 and the second body 1084 are not parallel, so that a specific angle is formed between the two, and the existence of this angle allows the connecting rod to move in a non-vertical manner during movement. This non-vertical movement can provide more flexibility and diversity for the operation of the mechanism. A second slot 1083 is provided on the first body 1082, and a third slot 1085 is provided on the second body 1084. The existence of these slots allows the connecting rod structure 108 to be connected to other components and perform relative movement. The position and angle of the slot can affect the movement trajectory and range of the connecting rod, so that the mechanism can achieve more diverse movement modes.

[0060] In general, the design of the connecting rod structure 108 allows the tray mechanism 100 to move at different angles and directions and to achieve more diverse operation modes. The flexibility and diversity of this design can bring more options and possibilities to the design of the lifting tray mechanism 100 to meet the use requirements in different scenarios.

[0061] In some embodiments, optionally, the movement of the control rod 104 is the starting action of the entire unlocking and lifting process. Specifically, when the user pushes and pulls the control rod 104, as shown in FIG. Figure 3 As shown, it moves along a first direction (usually a front-to-back direction). This movement is achieved by direct manual operation by a user, or by other mechanical means (such as buttons, levers, etc.). One end of the connecting rod structure 108 is movably connected to the control rod 104, and the other end is movably connected to the slider structure 106. The movement of the control rod 104 causes the connecting rod structure 108 to rotate around its rotation point (which may be a pivot or support shaft). Since the first body 1082 and the second body 1084 are not parallel, this rotation of the connecting rod causes the slider structure 106 to move along a specific trajectory.

[0062] The slider structure 106 moves toward the inside of the base structure 102 as the link structure 108 rotates. This inward movement is performed along the slide groove or guide rail on the base structure 102, and this movement is to unlock the card position. The card position is usually a mechanical locking mechanism used to keep the tray immobile when it reaches a specific position.

[0063] When the slider structure 106 moves inwardly, it interacts with the detent mechanism to release the locked state. This usually involves the slider moving away from a groove or protrusion that holds the tray in place.

[0064] Once the catch is unlocked, the tray can be raised and lowered freely. The user can continue to operate the control lever 104 to adjust the tray to the desired height, or the tray may rise automatically, depending on the design of the mechanism and the effect of gravity.

[0065] Users can unlock and adjust the position of the tray through simple operations, making it easy and convenient to access items or adjust storage space.

[0066] In some embodiments, optionally, Figure 5 and Figure 6 As shown, the mounting groove 1022 is arranged on the base structure 102, and is used to install and fix the rod body 1042 of the control rod 104. This groove can ensure that the control rod 104 is correctly positioned and fixed on the base structure 102, so that it can be moved and operated stably. The first slide groove 1024 is also arranged on the base structure 102, and the sliding part 1044 of the control rod 104 cooperates with it. The function of this slide groove is to guide the sliding of the control rod 104, so that the control rod 104 can move along a predetermined path. The design and position of the first slide groove 1024 will directly affect the movement track and range of the control rod 104. The control rod 104 is composed of a rod body 1042 and a sliding part 1044 connected to the rod body 1042. The rod body 1042 is arranged in the mounting groove 1022, and ensures that the control rod 104 is correctly installed on the base structure 102. The sliding portion 1044 is slidably matched with the first sliding groove 1024 , so that the control rod 104 can slide freely in the sliding groove, thereby realizing the corresponding operating function.

[0067] By moving the control rod 104, the sliding part 1044 slides in the first slide groove 1024, so that the mechanism can be controlled and operated. The existence of the mounting groove 1022 ensures the stable installation of the control rod 104, while the design and position of the first slide groove 1024 affect the movement trajectory of the control rod 104. The flexibility and stability of this design can provide reliable operating performance for the lifting tray mechanism 100.

[0068] In some embodiments, the second slide groove 1026 optionally serves to provide a sliding connection for the slider structure 106, so that the slider structure 106 can slide freely on the base structure 102. This ensures that the slider structure 106 can slide smoothly along the second slide groove 1026, thereby achieving a reliable connection with the base structure 102. This sliding connection is to enable the slider structure 106 to achieve corresponding movement in the lifting tray mechanism 100 under the action of the control rod 104.

[0069] The design of the second slide groove 1026 provides a stable sliding connection for the slider structure 106 , so that the slider can slide smoothly on the base structure 102 , thereby realizing the movement function of the lifting tray mechanism 100 .

[0070] In some embodiments, optionally, Figure 4 As shown, the first column 1028 is a component of the base structure 102, and the connecting rod structure 108 is provided with a first shaft hole 1081 that matches the first column 1028, so that it can be rotatably connected with the base structure 102. The connecting rod structure 108 can match with the first column 1028 through the first shaft hole 1081, so as to achieve rotation around the axis of the first column 1028.

[0071] This design allows the connecting rod structure 108 to keep coordination with the base structure 102 during rotation and transmit appropriate power and movement. This rotation connection allows the connecting rod structure 108 to move at different angles and directions to meet the operating requirements of the lifting tray mechanism 100.

[0072] In some embodiments, optionally, the slider structure 106 is provided with a second column 1062, and the connecting rod structure 108 is provided with a second slot 1083 corresponding to the second column 1062. This design enables the slider structure 106 to achieve relative rotation and sliding connection with the connecting rod structure 108. The second column 1062 is located in the second slot 1083, ensuring that the slider structure 106 can stay firmly at the specified position.

[0073] When the slider structure 106 moves along the first slide groove 1024, the cooperation between the second column 1062 and the second slot 1083 enables the slider structure 106 to rotate and slide accordingly under the drive of the connecting rod structure 108, thereby unlocking the position and realizing the lifting and lowering of the tray. This design increases the stability and reliability of the mechanism and improves the operating performance.

[0074] In some embodiments, optionally, the control rod 104 is provided with a third column 1046, and the connecting rod structure 108 is provided with a third slot 1085 corresponding to the third column 1046. This design enables the control rod 104 and the connecting rod structure 108 to achieve relative rotation and sliding connection. The third column 1046 is located in the third slot 1085, ensuring that the control rod 104 can stay firmly at the specified position. When the control rod 104 moves along the first direction, the connecting rod structure 108 will be driven by the control rod 104, and rotate and move in the third slot 1085 with the third column 1046, thereby driving the slider structure 106 to move along the first slide groove 1024, unlocking the position and realizing the lifting and lowering of the tray.

[0075] This design increases the stability and reliability of the mechanism operation and improves the operational performance. At the same time, the cooperation between the third column 1046 and the third slot 1085 can also play a limiting role, ensuring that the control rod 104 does not exceed the preset range during the movement, thereby ensuring the normal operation of the mechanism.

[0076] In some embodiments, optionally, Figure 5 and Figure 6 As shown, the fixing seat 112 is arranged on the base structure 102, the guide shaft 114 is arranged in the control rod 104, the reset member 110 is sleeved outside the guide shaft 114, and one end of the reset member 110 is connected to the fixing seat 112. The fixing seat 112 provides a fixed installation position for the reset member 110 to ensure that the reset member 110 can work stably and will not be displaced during the operation of the mechanism. The guide shaft 114 is located in the control rod 104. When the control rod 104 moves along the first direction, the guide shaft 114 will move with the control rod 104, thereby guiding the reset member 110 to move along the axis of the guide shaft 114.

[0077] The reset member 110 is sleeved outside the guide shaft 114, and one end of the reset member 110 is connected to the fixing seat 112. When the control rod 104 is pulled, the reset member 110 is compressed to store energy. When the control rod 104 is released, the reset member 110 releases energy to push the control rod 104 back to its original position.

[0078] The restoring force of the restoring member 110 helps maintain the stability of the tray. When the tray is in the raised or lowered position, the restoring member 110 provides a reverse force to prevent the tray from accidentally moving due to external force or gravity. Of course, the restoring force of the restoring member 110 can prevent the control rod 104 from moving uncontrollably and quickly after being released, thereby improving the safety of the operation.

[0079] The above structure enables the mechanism to maintain stability and safety during operation, and can automatically reset after the control rod 104 is released, thereby improving the service life and reliability of the mechanism.

[0080] This application proposes another storage device 200, such as Figure 7 As shown, the lifting rail 202 provides a stable support and guide for the tray mechanism 100, ensuring that the tray mechanism 100 can be lifted and moved smoothly. The lifting rail 202 is provided with at least one latching position. When the slider structure 106 of the tray mechanism 100 is engaged with the latching position, the tray mechanism 100 is locked at a specified position to prevent accidental movement. When the control rod 104 moves along the first direction, the slider structure 106 of the tray mechanism 100 is unlocked, thereby releasing the tray mechanism 100 so that it can be lifted and moved freely.

[0081] The design of the storage device 200 allows the user to easily adjust the position of the tray mechanism 100 through the control rod 104, thereby flexibly adjusting the storage space to meet different storage needs. In addition, through the storage device 200, the user can classify and store items on different trays and adjust the position of the trays as needed, thereby improving storage efficiency and convenience.

[0082] In a specific embodiment, a lifting tray mechanism in a refrigerator is proposed, comprising: a tray base; a spring assembly, arranged in a spring fixing seat of the tray base; a control rod, arranged in the middle position of the bottom of the tray base, and having a first drive shaft; a connecting rod, arranged on the supporting rotating shaft of the tray base, one end of which is connected to the driving shaft of the control rod; a slider, arranged on both sides of the bottom of the tray base, and having a second drive shaft; one end of the spring assembly is installed in the spring fixing seat of the tray base, and the other end of the spring assembly is fixed in the spring guide shaft of the control rod; one end of the connecting rod is connected to the first driving shaft of the control rod, the other end of the connecting rod is connected to the second driving shaft of the slider, and the middle empty space of the connecting rod is connected to the supporting rotating shaft of the tray base.

[0083] In other words, the lifting tray mechanism includes: a tray base (ie, a base structure), a spring assembly (ie, a reset member), a control rod, a connecting rod (ie, a connecting rod structure) and a slider (ie, a slider structure).

[0084] The tray base is provided with a control rod slot (i.e., a first slot) and a slider slot (i.e., a second slot), the control rod can slide in the control rod slot, the slider can slide in the slider slot, and the connecting rod and the supporting shaft form relative rotation.

[0085] The tray base is provided with a spring fixing seat (i.e., a fixing seat), which can limit the radial degree of freedom and one axial degree of freedom of the spring assembly; the control rod is provided with a spring guide shaft (i.e., a guide shaft), and a part of the spring assembly is sleeved on the spring guide shaft, which can limit the radial and one axial degree of freedom of the spring assembly; the control rod is connected to the tray base through the spring assembly, and the spring assembly is always in a compressed state. The control rod is in a stationary state due to the limiting action of the control rod slide groove, but can offset the pressure of the spring assembly and slide relatively under the action of external force.

[0086] The control rod is provided with a first driving shaft (i.e., the second column), and the connecting rod is provided with a first driving hole (second slot hole). The first driving shaft passes through the first driving hole, and the shaft diameter contacts with the inner wall of the hole to transmit pressure for mutual driving.

[0087] The tray base is provided with a supporting shaft (ie, a first column), the connecting rod is provided with a pivot hole (ie, a first shaft hole), the connecting rod is sleeved on the supporting shaft through the pivot hole, and can rotate around the supporting shaft.

[0088] The tray base is provided with a slider slot, and the slider can slide linearly in the slot.

[0089] The slider has a second driving shaft (i.e., the third column), the connecting rod has a second driving hole (i.e., the third slot), the second driving shaft passes through the second driving hole, and the shaft diameter contacts the inner wall of the hole to transmit pressure for mutual driving.

[0090] In the free state, the control rod is pushed to a position away from the edge of the tray base under the pressure of the spring assembly, and the connecting rod is fixed on the supporting shaft at a certain angle under the pressure of the first driving shaft above the control rod. The second driving hole of the connecting rod exerts pressure on the second driving shaft on the slider, thereby keeping the slider in an extended state relative to the tray base.

[0091] When someone pulls the control rod outward by hand, the spring assembly is compressed, the connecting rod rotates as the first driving shaft moves outward, and the corresponding sliding block contracts and slides under the action of the rotation of the connecting rod.

[0092] When the lifting tray is pushed upward, the slider slides inward due to the external force, and the second driving shaft on the slider pushes the connecting rod to rotate, thereby driving the control rod to offset the pressure of the spring assembly and slide slightly.

[0093] The control rod can slide in the slide groove of the tray base, and is pressed against the far end of the slide groove by a spring assembly. The control rod can be pulled back by hand. When the control rod slides back and forth, the raised shaft on the upper side drives one end of the connecting rod, forcing the connecting rod to rotate around the intermediate shaft. When the connecting rod rotates, the other end of the connecting rod will force the slider to slide left and right.

[0094] Under normal conditions, the slider is extended outwards to support and fix the entire pallet; when the control rod is pulled back manually, the slider is retracted through the connecting rod, and the pallet can be raised or lowered as a whole. Or, when the pallet is pushed upward manually, the slider is subjected to inward pressure, and the control rod is driven by the connecting rod to offset the pressure of the spring, and the entire pallet is pushed up after the slider is retracted.

[0095] Through the design of the connecting rod, one set of springs can meet two functions; the connecting rod uses the principle of leverage, and the arm length connected to the slider is longer than the arm length connected to the control rod, which can easily push upward and use the force exerted on the slider itself to offset the pressure of the spring, and there will be no situation where the pulling force is too small to be restored when the control rod is pulled by hand;

[0096] The connecting rod adopts a design of nearly 90° bend, which not only saves space but also ensures the vertical pressure of the shaft on the lever, reducing pressure loss; the end of the connecting rod connected to the control rod adopts a large opening design. When the slider is pushed upward, its stroke is short and the resistance to be overcome is small; when the control rod is pulled by hand, it needs to travel a larger stroke to drive the connecting rod, ensuring the feel of hand-pull operation.

[0097] According to the tray mechanism and storage device provided by the utility model, the control rod and the slider structure are connected by a connecting rod structure, so that the installation efficiency can be improved.
