[0025] The present patent will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present patent, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0026] Reference Figures 1 to 3 This application provides a freezer 100. The freezer 100 includes a cabinet body 1. The cabinet body 1 has a top opening 11. The freezer 100 includes a door 2. The door 2 is pivotally connected to the cabinet body 1. The door 2 is used to open and close the top opening 11. The freezer 100 includes a shelf 3. The shelf 3 has an open opening 31 at its upper end. The shelf 3 includes a connecting portion 32 rotatably connected to the door 2. The shelf 3 rises or falls as the door 2 is opened or closed. The freezer 100 includes a support member 4. The support member 4 includes a first end 41 rotatably connected to the shelf 3 and a second end 42 rotatably connected to the cabinet body 1. The support member 4 is used to support the shelf 3 so that the open opening 31 faces upward.

[0027] Reference Figure 4 and Figure 5 In the first embodiment of this application, the door body 2 is provided with a door body slide groove 21 that is slidably connected to the connecting part 32. During the opening or closing of the door body 2, the connecting part 32 rotates relative to the door body slide groove 21 and slides linearly relative to the door body slide groove 21. The support member 4 rotates relative to both the shelf 3 and the cabinet 1. Under the coordinated action of the connecting part 32, the door body slide groove 21, and the support member 4, the shelf 3 rises or falls with the opening or closing of the door body 2, while ensuring that the open opening 31 of the shelf 3 is always facing upward.

[0028] The connecting part 32 can slide linearly and rotate via the door slide groove 21, allowing the shelf 3 to rise smoothly when the door 2 opens and fall smoothly when it closes, preventing the shelf 3 from getting stuck or obstructed during lifting and lowering. The support member 4 connects both the shelf 3 and the cabinet 1. Driven by the door 2, it rotates relative to both the shelf 3 and the cabinet 1, providing stable support and a lifting path for the shelf 3, ensuring smooth movement. The position and length of the door slide groove 21 can be adjusted according to actual needs to accommodate more types of freezers 100 or shelves 3.

[0029] The coordinated action of the support 4 and the slide rail dynamically adjusts the angle of the shelf 3 during its lifting and lowering process, ensuring that the open opening 31 faces upwards. This prevents the shelf 3 from tilting, thus preventing items from tipping over or sliding out during lifting and lowering, ensuring the safety and ease of access for the items. The design of the shelf 3 rising as the door 2 opens raises the stored items to a height that is easier to access, reducing the need for users to bend over or reach deep into the shelves, and improving user comfort.

[0030] This embodiment achieves flexible lifting and lowering of the shelf 3 with the door 2 and keeps the open opening 31 always facing upward through the coordinated action of the door slide 21, the connecting part 32 and the support 4, which significantly improves the ease of use of the freezer 100, the safety of storing and retrieving items and the utilization rate of internal space, making it convenient for users to take and put items.

[0031] Reference Figure 6 In the second embodiment of this application, the cabinet 1 is provided with a cabinet slide groove 12 that is slidably connected to the second end 42. During the opening or closing of the door 2, the connecting part 32 rotates relative to the door 2, and the support member 4 rotates relative to the shelf 3. While rotating relative to the cabinet 1, the support member 4 also slides linearly relative to the cabinet 1. Under the coordinated action of the connecting part 32, the cabinet slide groove 12, and the support member 4, the shelf 3 rises or falls with the opening or closing of the door 2, while ensuring that the open opening 31 of the shelf 3 is always facing upward.

[0032] The support member 4 can slide linearly and rotate via the cabinet slide rail 12, allowing the shelf 3 to rise smoothly when the door 2 opens and descend smoothly when it closes, preventing the shelf 3 from getting stuck or obstructed during the raising and lowering process. The cabinet slide rail 12 acts as a guide, allowing the support member 4 to slide linearly along the cabinet slide rail 12 during the opening and closing of the door 2. The design of the cabinet slide rail 12 ensures that the support member 4 is constrained during operation, avoiding path deviation or shaking, making the shelf 3 rise and fall more smoothly with the door 2. Under the constraint of the cabinet slide rail 12, the support member 4 can cooperate with the connecting part 32 to dynamically adjust the angle of the shelf 3, keeping its open opening 31 always horizontal and preventing items from tilting or falling. Because the cabinet slide rail 12 provides a linear sliding trajectory for the support member 4, the shelf 3 rises to a position within the user's reach when the door 2 opens and descends to its storage position inside the cabinet 1 when closed, reducing the user's bending or reaching actions and optimizing the user experience. The position and length of the cabinet slide 12 can be adjusted according to actual needs to accommodate more types of freezers 100 or shelves 3.

[0033] This embodiment, through the coordinated design of the cabinet slide 12, support 4, and connecting part 32, realizes the smooth lifting and lowering of the shelf 3 as the door 2 opens or closes, and ensures that the opening always faces upward, thereby improving the convenience and stability of users in taking and putting in items and the space utilization efficiency of the freezer 100.

[0034] Reference Figure 7In the third embodiment of this application, the support member 4 includes a first support rod 43 and a second support rod 44 hinged to each other. The first support rod 43 has a first end 41. The second support rod 44 has a second end 42. During the opening or closing of the door 2, the connecting part 32 rotates relative to the door 2, the support member 4 rotates relative to the shelf 3, and the cabinet 1 also rotates. At the same time, the first support rod 43 and the second support rod 44 of the support member 4 rotate relative to each other. Under the coordinated action of the connecting part 32, the first support rod 43, and the second support rod 44, the shelf 3 rises or falls with the opening or closing of the door 2, while ensuring that the open opening 31 of the shelf 3 is always upward.

[0035] The first support rod 43 and the second support rod 44 are flexibly linked through a hinge point. Compared with a single rigid support structure, this allows for a smoother adjustment of the lifting trajectory of the shelf 3 and reduces operational obstruction. The relative rotation of the two support rods, combined with the rotation of the support rods relative to the shelf 3 and the cabinet 1, as well as the rotation of the connecting part 32 relative to the door 2, enables the shelf 3 to rise when the door 2 opens and fall when it closes. Furthermore, during the lifting and lowering process, the center of gravity of the shelf 3 can be dynamically adjusted to an appropriate position, and the angle of the shelf 3 can be adjusted to ensure that the open opening 31 always faces upwards, preventing items from tipping over or slipping, thus ensuring the safety of stored items.

[0036] The hinged design of the first support rod 43 and the second support rod 44 gives the support member 4 greater flexibility, allowing it to adapt to different door angles and movement trajectories, meeting more diverse design needs of the freezer 100. The length and hinge position of the support rods can be flexibly adjusted to fit shelves 3 of different sizes and shapes. The support member 4, in conjunction with the door 2 and the cabinet 1, realizes the lifting mechanism of the shelf 3, which can raise the shelf 3 to a position easily accessible to the user, and lower it to the storage height inside the cabinet 1 when closed, reducing the user's bending or reaching actions. The support member 4 forms a stable triangular structure through the hinge of the two support rods, providing multi-point support during lifting and lowering, reducing swaying, and ensuring the smooth operation of the shelf 3.

[0037] This embodiment employs a support member 4 consisting of a first support rod 43 and a second support rod 44 that are hinged together, and in conjunction with a connecting part 32, to achieve flexibility and stability in the raising and lowering of the shelf 3 with the door 2, ensuring the safety of the open opening 31 always facing upwards. At the same time, it takes into account the stability of the structure, the economy of cost, and the convenience of user use.

[0038] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 In one embodiment of this application, the door slide groove 21 extends in a direction perpendicular to the pivot axis 22 of the door body 2. The connecting portion 32 includes a pivot shaft inserted into the door slide groove 21.

[0039] The pivot of the connecting part 32 can slide within the slide groove and also rotate relative to the door body 2 under the constraint of the slide groove, providing a flexible dual movement mode. This makes the linkage between the door body 2 and the shelf 3 more natural and the lifting and lowering of the shelf 3 smoother. The extension direction of the door slide groove 21 is perpendicular to the pivot axis 22 of the door body 2, which allows the connecting part 32 to move closer to or away from the pivot axis 22 of the door body 2 during the opening and closing process. This dynamically adjusts the lifting and lowering angle of the shelf 3, ensuring that the shelf 3 remains stable at different opening angles of the door body 2 and ensuring that the open opening 31 always faces upward.

[0040] Reference Figure 1 , Figure 4 , Figure 5 In one embodiment of this application, the door 2 can be hinged to the top of the rear wall of the cabinet 1, and the top opening 11 of the cabinet 1 can be opened by rotating the door 2 upward and backward. The pivot axis 22 of the door 2 extends horizontally to the left and right. The length direction of the door 2 is the extension direction of the pivot axis 22. The width direction of the door 2 is perpendicular to the pivot axis 22. The door slide 21 extends along the width direction of the door 2.

[0041] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 In one embodiment of this application, the inner wall of the door body 2 is provided with a first mounting protrusion 23 and a second mounting protrusion 24 symmetrically arranged on both sides of the shelf 3 along the pivot axis 22 of the door body 2. Both the first mounting protrusion 23 and the second mounting protrusion 24 have door body grooves 21 formed inside them. The connecting portion 32 includes a first connecting portion 321 that mates with the door body groove 21 of the first mounting protrusion 23 and a second connecting portion 322 that mates with the door body groove 21 of the second mounting protrusion 24.

[0042] The pivot of the first connecting part 321 is inserted into the door body slide groove 21 of the first mounting protrusion 23, and can rotate and slide relative to the door body slide groove 21 of the first mounting protrusion 23. The pivot of the second connecting part 322 is inserted into the door body slide groove 21 of the second mounting protrusion 24, and can rotate and slide relative to the door body slide groove 21 of the second mounting protrusion 24.

[0043] The first mounting protrusion 23 and the second mounting protrusion 24 are symmetrically arranged along the pivot axis 22 of the door body 2, providing support for the left and right sides of the shelf 3 respectively. Together with the first connecting part 321 and the second connecting part 322, they form a stable double-sided support structure, preventing the shelf 3 from swaying or tilting during lifting. The two opposing door body sliding grooves 21 formed inside the first mounting protrusion 23 and the second mounting protrusion 24 provide double-sided guiding constraints. Their sliding and rotating cooperation with the first connecting part 321 and the second connecting part 322 further improves the stability and movement accuracy of the shelf 3 during lifting. The symmetrical design ensures the synchronous movement of the left and right connecting parts 32 of the shelf 3, guaranteeing smooth and stable movement and preventing the shelf 3 from tilting or swaying.

[0044] The first mounting protrusion 23 and the second mounting protrusion 24 support the two sides of the shelf 3 respectively. Combined with the linkage of the double-sided door sliding groove 21 and the connecting part 32, the weight load of the shelf 3 can be evenly distributed, avoiding damage to components caused by excessive force at a single point, and improving the overall load-bearing capacity and durability of the system. The length of the door sliding groove 21 and the position of the mounting protrusions on the door 2 can be adjusted according to different specifications of the shelf 3. The first mounting protrusion 23 and the second mounting protrusion 24 can be integrally formed with the door 2. The first mounting protrusion 23 and the second mounting protrusion 24 are respectively located on the left and right sides of the shelf 3. The first connecting part 321 and the second connecting part 322 are respectively located at the left and right ends of the shelf 3.

[0045] Reference Figure 1 , Figures 4 to 8 In one embodiment of this application, the first end 41 of the support member 4 is located away from the connecting portion 32 along a direction perpendicular to the pivot axis 22 of the door body 2. This distance of the first end 41 from the connecting portion 32 makes the structural layout of the support member 4 more consistent with the mechanical requirements of lifting and lowering movements, thus enhancing the support effect on the shelf 3.

[0046] Reference Figure 1 , Figure 3 , Figure 6 In one embodiment of this application, the cabinet slide 12 extends in a direction perpendicular to the pivot axis 22 of the door 2. The second end 42 includes a pivot shaft that is inserted into the cabinet slide 12.

[0047] The cabinet slide 12 extends in a direction perpendicular to the pivot axis 22 of the door 2, which enables the second end 42 of the support 4 to make linear movements close to or away from the pivot axis of the door 2 during the opening and closing of the door 2. This ensures that the shelf 3 can rise and fall smoothly when the door 2 is opened or closed, and can better adjust the angle of the shelf 3 so that the shelf 3 always keeps the open opening 31 facing upward during the rising and falling process, preventing items from tipping over or slipping.

[0048] When the door 2 is pivotally connected to the top of the rear wall of the cabinet 1, and the pivot axis 22 of the door 2 extends horizontally to the left and right, the connecting part 32 can be set at the rear end of the shelf 3, the first end 41 can be installed close to the front end of the shelf 3, and the cabinet slide 12 can extend horizontally or obliquely along the width direction of the cabinet 1.

[0049] Reference Figure 1 , Figure 4 , Figure 6 In one embodiment of this application, the cabinet 1 includes a first sidewall 13 and a second sidewall 14 located on both sides of the shelf 3 along the pivot axis 22 of the door 2. The top of the inner side of the first sidewall 13 and the second sidewall 14 are recessed to form an installation space 15. The sidewalls of the installation space 15 are recessed to form cabinet slide grooves 12. The support member 4 includes a first support member 45 that cooperates with the cabinet slide groove 12 of the first sidewall 13 and a second support member 46 that cooperates with the cabinet slide groove 12 of the second sidewall 14. The first support member 45 and the second support member 46 are symmetrically arranged on both sides of the shelf 3 along the pivot axis 22 of the door 2.

[0050] When the door 2 is pivotally connected to the top of the rear wall of the cabinet 1, and the pivot axis 22 of the door 2 extends horizontally to the left and right, the first side wall 13 and the second side wall 14 refer to the left and right side walls of the cabinet 1, and the first support member 45 and the second support member 46 are symmetrically arranged on the left and right sides of the shelf 3.

[0051] The first support member 45 and the second support member 46 are symmetrically arranged on the left and right sides of the shelf 3, cooperating with the cabinet slide grooves 12 on the left and right side walls to form symmetrical double-sided support. This effectively avoids the shelf 3 from shifting or getting stuck due to force on one side, improving the reliability of operation and ensuring that the shelf 3 does not shake or tilt during lifting. The symmetrical support member 4 and cabinet slide groove 12 structure ensures the synchronicity of the angle adjustment of the shelf 3 during lifting, avoiding the opening offset caused by inconsistent angles on the left and right sides. The first support member 45 and the second support member 46 on both sides of the shelf 3 can jointly bear the weight of the shelf 3 and its stored items, distributing the force and reducing the risk of excessive force on one side or at one point.

[0052] The top of the left and right side walls of the cabinet 1 are recessed to form an installation space 15. The side walls of the installation space 15 are recessed to form a cabinet slide groove 12, which allows the support 4 to be placed at least partially within the installation space 15, avoiding occupying the effective storage space inside the freezer 100. The cabinet slide groove 12 is embedded in the installation space 15 of the side wall, which also makes the overall structure more robust, able to withstand greater loads and operating stresses, and ensure the long-term reliable operation of the system.

[0053] Reference Figure 4 , Figure 6In one embodiment of this application, the support member 4 includes a support member group 47 consisting of a plurality of first support members and second support members arranged parallel and spaced apart along the extension direction of the cabinet slide groove 12. A support member group 47 consists of a first support member 45 and a second support member 46 arranged symmetrically to each other.

[0054] When the door 2 is pivotally connected to the top of the rear wall of the cabinet 1, and the pivot axis 22 of the door 2 extends horizontally to the left and right, multiple support groups 47 can be arranged parallel and spaced apart in the front-back direction. The support 4 may include two groups of support groups 47 arranged spaced apart in the front-back direction.

[0055] The arrangement of multiple support groups 4 forms a denser support structure, increasing the uniformity of force distribution on the shelf 3 during lifting and lowering, effectively avoiding local swaying or tilting that may be caused by single-point support. The parallel-spaced support groups 4 are distributed on both sides of the shelf 3, further balancing its center of gravity and making it more stable during dynamic movement. The multiple support groups 4 are distributed along the extension direction of the cabinet slide 12, effectively dispersing the stress of the shelf 3 and the weight of its contents, reducing the risk of excessive pressure on individual support groups 4, and improving the overall load-bearing capacity. This embodiment, through the parallel-spaced arrangement of multiple support groups 47, can significantly enhance the stability, load-bearing capacity, and smooth lifting and lowering performance of the shelf 3.

[0056] Reference Figure 4 , Figure 6 In one embodiment of this application, the support member group 47 near the connecting portion 32 is higher than the support member group 47 far from the connecting portion 32.

[0057] When the door 2 is pivotally connected to the top of the rear wall of the cabinet 1, and the pivot axis 22 of the door 2 extends horizontally to the left and right, the rear support group 47 is higher than the front support group 47.

[0058] By having each set of support components 47 spaced apart and having different heights, it is possible to ensure that each set of support components 47 is independent of each other and avoid mutual interference. When there is a cabinet slide 12, it is also convenient to set the corresponding cabinet slide 12. The cabinet slide 12 sets corresponding to each set of support components 47 can be set up vertically and horizontally at intervals.

[0059] Reference Figures 4 to 6In one embodiment of this application, when the freezer 100 has a door slide 21 or a cabinet slide 12, the support member 4 includes only one support rod, which forms a first end 41 and a second end 42. The support member 4 consists of only one support rod, which significantly reduces the number of components compared to a multi-support rod design, lowering the complexity of production and assembly. The door slide 21 guides the movement of the connecting part 32, or the cabinet slide 12 guides the movement of the second end 42 of the support rod, providing a stable movement trajectory for the shelf 3, ensuring its smooth operation during lifting and lowering. The simplified structure of the support member 4 reduces uncertainties in dynamic movement, avoids potential movement conflicts in multi-rod systems, and improves the overall system stability.

[0060] By adopting a single support rod structure, combined with the guiding effect of the door slide 21 or cabinet slide 12, stable support and smooth lifting function of the shelf 3 are achieved, which not only reduces the complexity of the system and manufacturing cost, but also enhances the adaptability and safety of the system.

[0061] In one embodiment of this application, an assisted door hinge is provided between the cabinet body 1 and the door body 2. The freezer 100 includes two sets of support members 4 symmetrically arranged on the left and right sides of the shelf 3. The assisted door hinge can be an existing spring-assisted door hinge or the like. The assisted door hinge provides additional mechanical assistance for opening and closing the door body 2, which can reduce the force required for the user to operate the door body 2 and make it easier for the user to use the freezer 100.

[0062] In one embodiment of this application, the freezer 100 includes an electric push rod disposed within a cabinet slide groove 12. The electric push rod is used to push a second end 42 to slide within the cabinet slide groove 12. By providing an electric push rod drive support 4 within the cabinet slide groove 12, opening and closing the door 2 becomes easier.

[0063] The electric push rod can provide a smooth and continuous thrust, ensuring that the support 4 slides smoothly in the groove without jamming, making the shelf 3 rise and fall more smoothly. The electric push rod can also act in the opposite direction to the door 2 through the support rod, making it easier for users to operate. It can even realize the automatic opening and closing of the door 2 and the automatic raising and lowering of the shelf 3, significantly improving the user's ease of operation, system stability and safety.

[0064] In summary, the freezer 100 of this application can solve the problem of time-consuming and laborious manual movement of the shelf 3 in the existing design.

[0065] The design scheme of this application enables the shelf 3 to be flexibly raised and lowered with the door 2 and keep the open opening 31 always facing upward, which significantly improves the ease of use of the freezer 100, the safety of storing and retrieving items and the utilization rate of internal space, making it easier for users to put and take items.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0067] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this patent, and are not intended to limit the scope of protection of this patent.
