Description

Technical Field

[0001] This utility model relates to the field of kitchen cabinet technology, specifically a wall cabinet with lifting function. Background Technology

[0002] As people's demands for space utilization efficiency continue to increase, especially in homes and offices, the functionality and space utilization rate of furniture have become important criteria for designing and selecting furniture. Under this trend, various types of furniture with flexible storage functions have emerged. Among them, lift cabinets, which can achieve storage and retrieval through lifting, have gradually become one of the most popular products in the market due to their unique advantages in environments with limited space or where space utilization needs to be improved.

[0003] Currently, most lift cabinets on the market connect the movable cabinet to the fixed cabinet via a lifting mechanism, which enables the movable cabinet to move up and down. The basic working principle of a lift cabinet is that the lifting mechanism drives the movable cabinet to move up and down along a certain trajectory within the fixed cabinet, thereby achieving storage and retrieval functions. However, the lifting mechanism designs commonly used in existing technologies have some significant drawbacks, especially in terms of improving space utilization efficiency, which is difficult to fully optimize.

[0004] Most existing lifting cabinets use a four-bar linkage structure as their lifting mechanism. This four-bar linkage typically connects the various links through fixed hinge points, and the movement of the four links achieves the lifting and lowering of the cabinet. However, although the four-bar linkage structure can effectively achieve the lifting and lowering of the cabinet in principle, its design has several problems in practical applications, especially in terms of space optimization. First, because the hinge points of the existing four-bar linkage structure are fixed, a relatively long linkage is required to ensure that the moving cabinet avoids the bottom of the fixed cabinet during lifting. While this design can prevent the bottom of the moving cabinet from colliding with the bottom of the fixed cabinet, it creates a large gap between the two cabinets after the moving cabinet is closed. This gap is often not effectively utilized in actual use, resulting in significant space waste.

[0005] Especially in situations with limited space or high space utilization requirements, the presence of such gaps significantly impacts the space utilization efficiency of lift cabinets. In such cases, even if the lift cabinet itself has storage functions, the overall space utilization rate is not fully improved due to the bottom gap in the design, resulting in wasted space. Therefore, while existing four-bar lift cabinets can achieve lifting and lowering of movable cabinets, their performance in efficient space utilization is limited by the space wastage problem. In summary, although the lifting mechanism of existing lift cabinets achieves basic lifting functions in its design, the existence of space wastage makes it difficult to meet the application scenarios with higher requirements for space utilization. Therefore, it is necessary to improve the lifting mechanism in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a hanging cabinet with lifting function that is simple in structure, easy to use, ensures the movement function and stability of the lifting cabinet, reduces the gap between the moving cabinet and the fixed cabinet, and improves the space utilization rate.

[0007] The purpose of this utility model is achieved in the following way: a hanging cabinet with lifting function, which includes a fixed cabinet and a movable cabinet. The fixed cabinet and the movable cabinet are connected by a lifting mechanism. The lifting mechanism drives the movable cabinet to move relative to the fixed cabinet, so that the movable cabinet can be stored in the fixed cabinet or moved downward from the fixed cabinet.

[0008] The lifting mechanism includes a base installed inside a fixed cabinet, and a guide device connected to a sliding plate is provided on one side of the base, so that the sliding plate can slide back and forth relative to the base;

[0009] A first swing arm and a second swing arm are hingedly mounted on the sliding plate, and the other end of the first swing arm and the second swing arm is hinged to the movable cabinet.

[0010] The first swing arm is also connected to a drive arm, and a track wheel is provided at the other end of the drive arm; a track groove is provided on the base accordingly, and the track wheel extends into the track groove to slide.

[0011] When the mobile cabinet is raised or lowered, the swing of the first swing arm drives the drive arm to move the track wheel in the track groove, thereby driving the sliding plate to slide relative to the base.

[0012] Furthermore, the lifting mechanism is provided in two sets, which are respectively installed between the two inner side walls of the fixed cabinet and the two outer side walls of the movable cabinet.

[0013] Furthermore: the guiding device is a guide rail, and a guide block is slidably installed inside the guide rail, and the guide block is connected to the sliding plate.

[0014] Furthermore, the guiding device is a guide rail, in which a guide wheel is slidably installed, and the guide wheel is connected to a sliding plate.

[0015] Furthermore, the guide rail is a linear slide rail, which is horizontally mounted on the base.

[0016] Furthermore, the track groove is an "S"-shaped guide rail groove set on the side wall of the base, and the track groove protrudes from the side wall of the base.

[0017] Furthermore: the track groove is an "S"-shaped guide rail groove provided on the side wall of the base, and the track groove is a groove provided on the side wall of the base.

[0018] Furthermore, the track groove is an "S"-shaped guide rail groove set on the base, and the track groove runs through the base.

[0019] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0020] 2. This utility model, through its innovative lifting mechanism design, avoids the bottom gap problem present in existing four-bar linkage structures. The lifting mechanism drives the lifting and translation of the movable cabinet through the relative movement of the sliding plate and the track groove, eliminating the reliance on fixed hinge points for movement and thus reducing the gap between the movable cabinet and the fixed cabinet when closed. This significantly reduces the bottom gap between the movable cabinet and the fixed cabinet when closed, greatly improving the effective utilization of space, especially in situations with limited space or high space utilization requirements, where it has a clear advantage.

[0021] 3. This utility model achieves smooth lifting and lowering of the mobile cabinet through the coordinated action of the first and second swing arms and the sliding of the track wheel by the drive arm within the track groove. This structure enables efficient and smooth lifting and lowering movements, enhancing the user experience. Whether storing or retrieving items, the lifting and lowering motion of the mobile cabinet is more precise, avoiding the complex mechanical problems caused by long connecting rods in traditional four-bar linkage structures.

[0022] 4. By using the combination of track groove and track wheel, the lifting mechanism of this utility model can ensure the stable movement of the sliding plate during the lifting process, so that the lifting and translation trajectory of the mobile cabinet is stable.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. A hanging cabinet with lifting function includes a fixed cabinet 1 and a movable cabinet 2. The fixed cabinet 1 and the movable cabinet 2 are connected by a lifting mechanism. The lifting mechanism drives the movable cabinet 2 to move relative to the fixed cabinet 1, so that the movable cabinet 2 can be stored in the fixed cabinet 1 or moved downward from the fixed cabinet 1.

[0028] The lifting mechanism includes a base 3 installed inside the fixed cabinet 1. A guide device is provided on one side of the base 3 and connected to a sliding plate 4, so that the sliding plate 4 can slide back and forth relative to the base 3.

[0029] The sliding plate 4 is hinged to a first swing arm 5 and a second swing arm 6, and the other end of the first swing arm 5 and the second swing arm 6 is hinged to the movable cabinet 2.

[0030] The first swing arm 5 is also connected to a drive arm 7, and a track wheel 71 is provided at the other end of the drive arm 7; correspondingly, a track groove 31 is provided on the base 3, and the track wheel 71 extends into the track groove 31 to slide.

[0031] When the mobile cabinet is raised or lowered, the swing of the first swing arm 5 drives the drive arm 7 to drive the track wheel 71 to slide in the track groove 31, thereby driving the sliding plate 4 to slide relative to the base 3.

[0032] In one embodiment, two sets of lifting mechanisms are provided, which are respectively installed between the two inner side walls of the fixed cabinet 1 and the two outer side walls of the movable cabinet 2.

[0033] In one embodiment: the guiding device is a guide rail 8, and a guide block 9 is slidably installed inside the guide rail 8. The guide block 9 is connected to the sliding plate 4.

[0034] In one embodiment: the guiding device is a guide rail 8, and a guide wheel is slidably installed in the guide rail 8, and the guide wheel is connected to the sliding plate 4.

[0035] In one embodiment: the guide rail 8 is a linear slide rail, which is horizontally mounted on the base 3.

[0036] In one embodiment: the track groove 31 is an "S"-shaped guide rail groove provided on the side wall of the base 3, and the track groove 31 protrudes from the side wall of the base 3.

[0037] In one embodiment: the track groove 31 is an "S"-shaped guide rail groove provided on the side wall of the base 3, and the track groove 31 is a groove provided on the side wall of the base 3.

[0038] In one embodiment: the track groove 31 is an "S"-shaped guide rail groove provided on the base 3, and the track groove 31 is provided through the base 3.

[0039] In this case, the lifting mechanism consists of components such as a base 3, a sliding plate 4, a first swing arm 5, a second swing arm 6, a drive arm 7, and a track groove 31. The base 3 is fixedly installed inside the fixed cabinet 1, while the sliding plate 4 is connected to the base via a guide device and a sliding connection. The movable cabinet 2 is connected to the sliding plate via the swing arm. During the lifting process, the sliding of the sliding plate drives the movable cabinet to move back and forth.

[0040] When the user needs to raise or lower the mobile cabinet 2, the track groove 31 in the base 3 provides the translational trajectory for the mobile cabinet 2. The drive arm 7 is connected to the first swing arm 5 and drives the track wheel 71 to slide within the track groove 31. Due to the "S"-shaped design of the track groove, when the track wheel 71 moves within the track groove 31, it can push the sliding plate outward when the cabinet is lowered, causing the hinge points between the first and second swing arms and the fixed cabinet to translate outward. When closed, the track groove pushes the sliding plate inward, thereby pushing the mobile cabinet inward into the fixed cabinet. This not only ensures the smooth movement of the mobile cabinet 2 but also effectively avoids collisions between the bottom of the mobile cabinet and the fixed cabinet.

[0041] As the track wheel 71 slides within the track groove 31, the drive arm 7 drives the sliding plate 4 to slide along the base 3 in the front-to-back direction. The swinging of the first swing arm 5 and the second swing arm 6 enables the mobile cabinet 2 to move stably back and forth during lifting and lowering. This ensures that the mobile cabinet, when opening and closing, not only has lifting motion but also front-to-back translational motion.

[0042] One key point to note is that, unlike existing four-bar linkage lifting cabinets, this invention utilizes a hinged design between the movable first and second swing arms. This allows the lifting cabinet to first slide outwards during descent, ensuring the bottom of the movable cabinet is aligned with the fixed cabinet before it moves downwards, achieving the purpose of lowering the movable cabinet. Therefore, compared to traditional technologies, it reduces the bottom gap between the movable cabinet 2 and the fixed cabinet 1 after closing, effectively avoiding wasted space. This design offers significant technical advantages for applications with limited space or high space utilization requirements, providing a higher space utilization rate.

[0043] To ensure the smooth operation of the sliding plate 4 during lifting, this invention employs a combination of guide rail 8 and guide block 9 or guide wheel. The guide rail 8 is mounted on the base 3, while the guide block 9 or guide wheel is connected to the sliding plate 4, ensuring stability during sliding. The design of the guiding device ensures that the mobile cabinet does not deviate from its trajectory during lifting, increasing the system's stability and safety.

[0044] In summary, the working principle of this utility model's lifting cabinet, through its simple and efficient lifting mechanism design, solves the problems of space waste and unstable lifting in existing technologies. Through the cooperation of the track groove and track wheels, as well as the coordinated movement of the sliding plate and swing arm, the cabinet remains stable during lifting, and the bottom gap is greatly reduced, significantly improving space utilization. These technical advantages give this utility model's lifting cabinet significant advantages in functionality, stability, and cost-effectiveness, meeting the needs of modern homes and offices for efficiency, flexibility, and space saving.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
