Description

Technical Field

[0001] The invention relates to the technical field of kitchen cabinets, in particular to a wall cabinet with a lifting function. Background Art

[0002] As people's requirements for space utilization efficiency continue to increase, especially in the fields of home and office, the functionality and space utilization of furniture have become important criteria for designing and selecting furniture. Under this trend, various furniture with flexible storage functions have emerged. Among them, lifting cabinets, as a kind of furniture that can store and retrieve items by lifting, have unique advantages in environments with small spaces or where space utilization needs to be improved, and have gradually become one of the most popular products in the market.

[0003] At present, most of the lifting cabinets on the market connect the movable cabinet with the fixed cabinet through a lifting mechanism, and realize the lifting movement of the movable cabinet through this mechanism. The basic working principle of the lifting cabinet is usually to drive the movable cabinet to move up and down along a certain track in the fixed cabinet through the lifting mechanism, so as to realize the storage and retrieval functions. However, the lifting mechanism design commonly used in the prior art has some significant disadvantages, especially in terms of improving the efficiency of space utilization, it is difficult to fully optimize.

[0004] Among them, the existing lifting cabinets mostly use a four-link structure as the lifting mechanism. This four-link structure usually connects the various connecting rods through a fixed hinge point, and the lifting and lowering of the movable cabinet is achieved through the movement of the four connecting rods. However, although the four-link structure can effectively realize the lifting and lowering movement of the movable cabinet in principle, in actual application, its design has the following problems, especially in terms of space optimization. First of all, since the hinge point of the existing four-link structure is fixed, in order to ensure that the movable cabinet can avoid the bottom of the fixed cabinet during the lifting process, a longer connecting rod length needs to be designed. Although this design can avoid the collision between the bottom of the movable cabinet and the fixed cabinet, after the movable cabinet is closed, a large bottom gap is formed between the fixed cabinet and the movable cabinet. This gap is often not effectively utilized in actual use, resulting in significant waste of space.

[0005] Especially in situations where space is tight or there are high requirements for space utilization, the existence of this gap greatly affects the space utilization efficiency of the lifting cabinet. In this case, even if the lifting cabinet itself has a storage function, due to the bottom gap existing in the design, the overall space utilization rate has not been fully improved, but the available space is wasted. Therefore, although the existing lifting cabinet with a four-link structure can realize the lifting of the movable cabinet, its performance in efficient space utilization is limited due to the problem of space waste. In summary, although the lifting mechanism of the existing lifting cabinet has realized the basic lifting function in design, it is difficult to meet the application scenarios with higher requirements for space utilization due to the existence of the space waste problem. Therefore, it is necessary to improve the lifting mechanism in the prior art. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a wall cabinet with a 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 movable cabinet and the fixed cabinet, and improves space utilization.

[0007] The object of the present invention is achieved in the following manner: a wall cabinet with a lifting function, comprising a fixed cabinet and a movable cabinet, wherein the fixed cabinet and the movable cabinet are connected via a lifting mechanism, and 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 swung downward from the fixed cabinet; The lifting mechanism comprises a base installed in a fixed cabinet, and a guide device is provided on one side of the base to connect with the sliding plate so that the sliding plate can slide forward and backward relative to the base; The sliding plate is hingedly mounted with a first swing arm and a second swing arm, and the other ends of the first swing arm and the second swing arm are hingedly connected to the movable cabinet; The first swing arm is also connected to a driving arm, and a track wheel is arranged at the other end of the driving arm; a track groove is correspondingly arranged on the base, and the track wheel extends into the track groove and slides; When the movable cabinet is lifted or lowered, the first swing arm swings, driving the driving arm to drive the track wheel to slide in the track groove, thereby driving the sliding plate to slide relative to the base.

[0008] Furthermore: the lifting mechanism is provided with two sets, which are respectively installed between the two inner walls of the fixed cabinet and the two outer walls of the movable cabinet.

[0009] Furthermore: the guide device is a guide rail, a guide block is slidably installed in the guide rail, and the guide block is connected to the sliding plate.

[0013] Furthermore: the track groove is an "S"-shaped guide groove arranged on the side wall of the base, and the track groove is a groove arranged on the side wall of the base.

[0014] Furthermore: the track groove is an "S"-shaped guide groove arranged on the base, and the track groove runs through the base.

[0015] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0016] 2. The present invention avoids the bottom gap problem existing in the existing four-bar linkage structure through the innovative design of the lifting mechanism. The lifting mechanism drives the lifting and translation of the movable cabinet through the relative movement of the sliding plate and the track groove, and no longer relies on the fixed hinge point to achieve movement, thereby reducing the gap between the movable cabinet and the fixed cabinet after closing. In this way, the bottom gap between the movable cabinet and the fixed cabinet is greatly reduced when closed, which greatly improves the effective utilization rate of the space, especially in occasions with limited space or high requirements for space utilization, which has obvious advantages.

[0017] 3. The present invention realizes the smooth lifting of the movable cabinet through the synergistic effect of the first swing arm and the second swing arm and the driving arm driving the track wheel to slide in the track groove.

[0023] The present invention is further described in detail below with reference to the accompanying drawings. A wall cabinet with a lifting function comprises a fixed cabinet 1 and a movable cabinet 2, wherein the fixed cabinet 1 and the movable cabinet 2 are connected via a lifting mechanism, and 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; The lifting mechanism comprises a base 3 installed in the fixed cabinet 1, and a guide device is provided on one side of the base 3 to connect with the sliding plate 4, so that the sliding plate 4 slides forward and backward relative to the base 3; The sliding plate 4 is hingedly mounted with a first swing arm 5 and a second swing arm 6, and the other ends of the first swing arm 5 and the second swing arm 6 are hingedly connected to the movable cabinet 2; The first swing arm 5 is also connected to a driving arm 7, and a track wheel 71 is provided at the other end of the driving 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; When the movable cabinet is lifted or lowered, the first swing arm 5 swings, driving the driving 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 .

[0024] In one embodiment, two sets of the lifting mechanisms are provided, which are respectively installed between the two inner walls of the fixed cabinet 1 and the two outer walls of the movable cabinet 2 .

[0025] In one of the embodiments, the guide device is a guide rail 8 , a guide block 9 is slidably installed in the guide rail 8 , and the guide block 9 is connected to the sliding plate 4 .

[0026] In one embodiment, the guide device is a guide rail 8 , a guide wheel is slidably installed in the guide rail 8 , and the guide wheel is connected to the sliding plate 4 .

[0027] In one embodiment, the guide rail 8 is a linear slide rail, which is horizontally installed on the base 3.

[0028] In one embodiment, the track groove 31 is an “S”-shaped guide groove arranged on the side wall of the base 3 , and the track groove 31 protrudes from the side wall of the base 3 .

[0029] In one embodiment, the track groove 31 is an “S”-shaped guide groove arranged on the side wall of the base 3 , and the track groove 31 is a groove arranged on the side wall of the base 3 .

[0030] In one embodiment, the track groove 31 is an “S”-shaped guide groove arranged on the base 3 , and the track groove 31 penetrates the base 3 .

[0031] Working principle, in this case, the lifting mechanism is composed of a base 3, a sliding plate 4, a first swing arm 5, a second swing arm 6, a driving arm 7 and a track groove 31. The base 3 is fixedly installed in the fixed cabinet 1, and the sliding plate 4 is connected to the base through a guide device and a sliding connection. The movable cabinet 2 is connected to the sliding plate through a swing arm. During the lifting process, the sliding of the sliding plate drives the movable cabinet to move forward and backward.

[0032] When the user needs to raise or lower the movable cabinet 2, the track groove 31 in the base 3 provides a translation track for the movable cabinet 2. The driving arm 7 is connected to the first swing arm 5, and drives the track wheel 71 to slide in the track groove 31. Due to the "S"-shaped design of the track groove, when the track wheel 71 moves in the track groove 31, it can push the sliding plate to move outward when the cabinet body descends downward, so that the hinge points between the first swing arm and the second swing arm and the fixed cabinet are translated outward, and when closing, the track groove pushes the sliding plate to translate inward, thereby pushing the movable cabinet to translate inward into the fixed cabinet. Not only does it ensure the stability of the movement of the movable cabinet 2, but it also effectively avoids the collision between the movable cabinet and the bottom of the fixed cabinet.

[0033] As the track wheel 71 slides in the track groove 31, the driving arm 7 drives the sliding plate 4 to slide along the front-back direction of the base 3. As the first swing arm 5 and the second swing arm 6 swing, the movable cabinet 2 can stably move forward and backward during the lifting process. When the movable cabinet is opened and closed, it not only has lifting movement, but also has front-back translation movement.

[0034] It is important to note that, unlike the existing lifting cabinets with four-link structure, the present invention uses the movable first swing arm and the second swing arm hinge point design, so that when the lifting cabinet is lowered, it first moves outward, so that the bottom of the movable cabinet is fixed to the fixed cabinet, and then moves downward, so as to achieve the purpose of lowering the movable cabinet. Therefore, compared with the traditional technology, it reduces the bottom gap between the movable cabinet 2 and the fixed cabinet 1 after closing. Thereby, the waste of space is effectively avoided. This design has significant technical advantages for applications with limited space or high requirements for space utilization, and can provide higher space utilization.

[0035] In order to ensure that the sliding plate 4 runs smoothly during the lifting process, the present invention adopts a combination of a guide rail 8 and a guide block 9 or a guide wheel. The guide rail 8 is installed on the base 3, and the guide block 9 or the guide wheel is connected to the sliding plate 4 to ensure that the sliding plate remains stable during the sliding process. The design of the guide device ensures that the movable cabinet does not deviate from the track during the lifting process, thereby increasing the stability and safety of the system.

[0036] In summary, the working principle of the lifting cabinet of the present invention solves the problems of space waste and unstable lifting in the prior art through the design of a simple and efficient lifting mechanism. Through the cooperation of the track groove and the track wheel and the coordinated movement of the sliding plate and the swing arm, the movable cabinet remains stable during the lifting process, and the bottom gap is greatly reduced, which significantly improves the space utilization rate. These technical advantages make the lifting cabinet of the present invention have obvious advantages in functionality, stability, cost-effectiveness, etc., and can meet the needs of modern homes, offices and other occasions for efficiency, flexibility and space saving.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims created by the present invention.
