Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a built-in lifting module and self-lifting furniture. Background Technology

[0002] In modern home design and life, furniture not only needs to meet basic functional requirements, but its aesthetic appeal is also receiving increasing attention. To achieve a simple, cohesive visual effect and avoid the cluttered feeling associated with traditional legs, many pieces of furniture on the market today, such as sofas, beds, wardrobes, and cabinets, commonly adopt a floor-standing design with their bases directly touching the ground. This legless design makes the furniture appear stable and grand, exuding a strong minimalist style and enhancing the overall aesthetics of the space.

[0003] However, this aesthetically pleasing design has led to a significant pain point in practical use: cleaning difficulties. Because there is almost no gap, or a very small gap, between the bottom of the furniture and the ground, common cleaning tools (such as brooms, mops, and robot vacuums) cannot reach underneath. When cleaning such areas, users often have to expend considerable physical effort to lift the furniture, a process that is extremely inconvenient and carries the risk of the furniture falling due to excessive force, potentially damaging the furniture or the floor.

[0004] Therefore, existing furniture needs to be improved to solve the problem that it requires users to expend a lot of physical effort to lift, which makes cleaning inconvenient.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a built-in lifting module and self-lifting furniture, which can effectively solve the problem that existing furniture requires users to expend a lot of physical effort to lift it, resulting in inconvenience for cleaning.

[0007] To achieve the above objectives, on the one hand, this utility model provides a built-in lifting module for placement in a lateral opening slot of the furniture body, comprising:

[0008] Support base;

[0009] The decorative panel unit includes a decorative panel for covering the lateral opening of the lateral opening slot, and a decorative panel connecting assembly for connecting the decorative panel to the support base.

[0010] The lifting direct drive mechanism is mounted on the support base and has a lifting state that moves upward to raise the furniture body; and a lowering state that moves downward to lower the furniture body.

[0011] Optionally, the trim panel connection assembly includes:

[0012] A first connecting rod, one end of which is rotatably connected to the support base;

[0013] The second link has one end rotatably connected to the other end of the first link, and the other end of the second link is connected to the decorative panel.

[0014] Optionally, the second link is detachably connected to the decorative panel.

[0015] Optionally, the detachable connection structure includes magnetic connection, snap-fit ​​connection, interference fit connection, or adhesive connection.

[0016] Optionally, the first link and the support base, and / or the first link and the second link, are hinged about a vertical pivot.

[0017] Optionally, the first link and the support base, and / or the first link and the second link, are omnidirectionally connected by a ball joint.

[0018] Optionally, the lifting direct drive mechanism includes a fixed sleeve fixed on the support base, a sliding sleeve whose lower end is inserted into the fixed sleeve and slidably connected to the fixed sleeve, and a sleeve direct drive mechanism for lifting the sliding sleeve upward.

[0019] Optionally, the top surface of the fixed sleeve is provided with a sleeve through hole for the upper part of the sliding sleeve to pass through, and the lower part of the sliding sleeve is provided with a stop boss that protrudes radially to restrict the sliding sleeve from completely passing through the sleeve through hole.

[0020] Optionally, the sleeve direct drive mechanism includes an organ airbag located below the sliding sleeve and an inflation / deflation system for inflating and deflating the organ airbag.

[0021] On the other hand, a self-lifting furniture is provided, including:

[0022] The furniture body has a lateral opening groove on at least one side;

[0023] A plurality of built-in lifting modules are provided, each corresponding to one of the side opening slots. The built-in lifting modules are placed in the corresponding side opening slots, and the decorative panels of the built-in lifting modules cover the side openings of the corresponding side opening slots.

[0024] The beneficial effects of this utility model are as follows: It provides a built-in lifting module and self-lifting furniture, in which a corresponding number of built-in lifting modules can be installed in one, two, or more side opening slots of the furniture body. In the non-lifting normal state, the decorative panel can perfectly cover the side openings, maintaining the integrity of the appearance.

[0025] When cleaning is required, proceed according to the actual needs:

[0026] Localized cleaning: For example, when only the underside of a specific corner of furniture needs cleaning, activate a single built-in lifting module housed in the corresponding lateral opening slot for that corner. The lifting mechanism of this module enters the lifting state, moving upwards and lifting the corresponding corner of the furniture body via the support base, exposing the underside space for cleaning. After cleaning, control the lifting mechanism of the module to enter the lowering state, moving downwards to lower the furniture body.

[0027] Thorough Cleaning: When cleaning the entire bottom of the furniture, simultaneously activate multiple (e.g., two or four) built-in lifting modules located under the furniture body. The lifting direct-drive mechanisms of each built-in lifting module synchronously enter the lifting state, moving upwards together to lift one side or the entire furniture body off the ground. After cleaning, control all built-in lifting modules to descend.

[0028] When the furniture is in the lifted position, the decorative panel will move relative to the support base and the furniture body, causing the side opening of the side opening slot to be partially or completely exposed. However, since the lifting operation is short-lived, this temporary exposure of the opening is acceptable.

[0029] Therefore, the built-in lifting module and self-lifting furniture provided by this utility model can effectively solve the problem that existing furniture requires users to expend a lot of physical strength to lift it, resulting in inconvenience for cleaning. Attached Figure Description

[0048] This invention provides a built-in lifting module and self-lifting furniture, which can effectively solve the problem that existing furniture requires users to expend a lot of physical effort to lift, resulting in inconvenience for cleaning.

[0049] See Figure 1 The self-lifting furniture provided in this embodiment includes:

[0050] Furniture body 2, wherein at least one side of the furniture body 2 is provided with a lateral opening groove 201 with a lateral opening;

[0051] A plurality of built-in lifting modules 1 are provided, each corresponding to one of the side opening slots 201, and the built-in lifting modules 1 are placed in the corresponding side opening slots 201.

[0052] Optionally, the furniture body 2 can be a sofa, bed, wardrobe, or cabinet, etc. This embodiment does not limit this. Furthermore, depending on the specific usage scenario, the side opening groove 201 can be set in a relatively inconspicuous position such as the left or right side or the back of the furniture body 2.

[0053] Specifically, the built-in lifting module 1, placed in the side opening slot 201 of the furniture body 2, includes:

[0054] Support base 101;

[0055] Decorative panel unit 102, the decorative panel unit 102 includes a decorative panel 1021 for covering the lateral opening of the lateral opening slot 201, and a decorative panel connecting assembly 1022 connecting the decorative panel 1021 to the support base 101.

[0056] The lifting direct drive mechanism 103 is mounted on the support base 101 and has a lifting state in which it moves upward to lift the furniture body 2; and a lowering state in which it moves downward to lower the furniture body 2.

[0057] It should be noted that a corresponding number of built-in lifting modules 1 can be installed in one, two or more side opening slots 201 of the furniture body 2. In the normal non-lifting state, the decorative panel 1021 can perfectly cover the side openings and maintain the integrity of the appearance.

[0058] When cleaning is required, proceed according to the actual needs:

[0059] Localized cleaning: For example, when only the underside of a corner of the furniture needs cleaning, a single built-in lifting module 1 is activated, located in the corresponding lateral opening slot 201 of that corner. The lifting direct drive mechanism 103 of the built-in lifting module 1 enters the lifting state, moves upward, and lifts the corresponding corner of the furniture body 2 upward via the support base 101, exposing the bottom space for cleaning. After cleaning, the lifting direct drive mechanism 103 of the built-in lifting module 1 is controlled to enter the lowering state, moving downward to lower the furniture body 2.

[0060] Thorough Cleaning: When the entire bottom of the furniture needs cleaning, simultaneously activate multiple (e.g., two or four) built-in lifting modules 1 located under the furniture body 2. The lifting direct drive mechanism 103 of each built-in lifting module 1 enters the lifting state synchronously, moving upwards together to lift one side or the entire furniture body 2 off the ground. After cleaning is complete, control all built-in lifting modules 1 to descend.

[0061] In the lifted state, the decorative panel 1021 will move relative to the support base 101 and the furniture body 2, causing part or all of the side opening of the side opening slot 201 to be exposed. However, since the lifting operation lasts for a short time, this temporary exposure of the opening is acceptable.

[0062] Therefore, the built-in lifting module 1 and self-lifting furniture provided by this utility model allow users to easily lift the furniture partially or completely through the lifting function of the built-in lifting module 1, making it easier for cleaning tools to access the bottom space. At the same time, in the non-lifted normal state, the decorative panel 1021 perfectly conceals the side openings, maintaining the overall appearance and aesthetics of the furniture, achieving a balance between function and aesthetics.

[0063] In this embodiment, the decorative panel connection assembly 1022 includes:

[0064] The first connecting rod 1022a, one end of which is rotatably connected to the support base 101;

[0065] The second link 1022b has one end rotatably connected to the other end of the first link 1022a, and the other end is connected to the decorative panel 1021.

[0066] The design of the first link 1022a and the second link 1022b allows the connection between the decorative panel 1021 and the furniture body 2 and the support base 101 to be no longer a rigid connection, but rather one with a degree of freedom of movement. The side opening slots 201 of different brands, batches, and even different locations on the same furniture have certain tolerances in terms of processing dimensions and positions. Because the decorative panel connecting components 1022 (first link 1022a, second link 1022b) provide multi-degree-of-freedom adjustment capabilities, the built-in lifting module 1 of the same specification can adapt to side opening slots 201 of different sizes and positions within a certain range. During installation, the position of the decorative panel 1021 can be precisely aligned and covered by manual adjustment, reducing the stringent requirements for furniture manufacturing precision.

[0067] Optionally, the second connecting rod 1022b is detachably connected to the decorative panel 1021. For example, the detachable connection can be achieved through magnetic connection, snap-fit ​​connection, interference fit connection, or adhesive connection.

[0068] The built-in lifting module 1 contains complex and precision components such as the lifting direct drive mechanism 103 and connecting rods, which constitute the main part of the cost. Through detachable connections, manufacturers can fully standardize the production of this core functional module. Regardless of the style, color, material, or size of furniture that this built-in lifting module 1 will ultimately be used in, its internal core mechanism will remain completely identical. This enables large-scale production of a single product, significantly reducing the complexity and cost of procurement, production, inventory management, and quality control.

[0069] The decorative panel 1021, as an exterior component, can be flexibly customized and replaced according to different furniture series (such as Nordic, industrial, and Chinese styles), different materials (such as wood veneer, metal, and plastic), and different colors. Furniture manufacturers do not need to redesign and produce the entire lifting module for each piece of furniture; they only need to equip the standardized core module with a specially designed new decorative panel 1021.

[0070] In this embodiment, the first connecting rod 1022a and the support base 101, and / or the first connecting rod 1022a and the second connecting rod 1022b, are hinged about a vertical axis. This hinge about a vertical axis provides a horizontal degree of rotational freedom, allowing the decorative panel 1021 to better adapt to positional deviations in the lateral opening slot 201, enhancing its adaptability to different installation conditions and improving coverage accuracy.

[0071] In some other embodiments, the first link 1022a and the support base 101, and / or the first link 1022a and the second link 1022b, are omnidirectionally connected via ball joints. The ball joint connection allows omnidirectional rotation in multiple directions between the first link 1022a and the support base 101, and / or between the first link 1022a and the second link 1022b, enabling multi-angle adjustment of the decorative panel 1021. This compensates for dimensional and positional errors of the lateral opening slot 201 in three-dimensional space, ensuring precise alignment of the decorative panel 1021 under various conditions and improving the module's fault tolerance and installation reliability.

[0072] See Figure 2 In this embodiment, the lifting direct drive mechanism 103 includes a fixed sleeve 1031 fixed to the support base 101, a sliding sleeve 1032 whose lower end is inserted into the fixed sleeve 1031 and slidably connected to the fixed sleeve 1031, and a sleeve direct drive mechanism 1033 for lifting the sliding sleeve 1032 upward. The sleeve direct drive mechanism 1033 includes an accordion airbag 1033a located below the sliding sleeve 1032, and an inflation / deflation system 1033b for inflating and deflation of the accordion airbag 1033a.

[0073] When lifting is required: the inflation / deflation system 1033b inflates the accordion airbag 1033a, causing the accordion airbag 1033a to expand and lift the sliding sleeve 1032 upwards, allowing the sliding sleeve 1032 to slide upwards and extend from the fixed sleeve 1031, thereby lifting the furniture body 2. When lowering is required: the inflation / deflation system 1033b deflates the accordion airbag 1033a, causing the accordion airbag 1033a to contract, and the sliding sleeve 1032 to slide downwards and retract into the fixed sleeve 1031 under gravity or external pressure, thus lowering the furniture body 2.

[0074] Furthermore, the top surface of the fixed sleeve 1031 is provided with a sleeve through hole for the upper part of the sliding sleeve 1032 to pass through, and the lower part of the sliding sleeve 1032 is provided with a stop boss 1032a that protrudes radially to restrict the sliding sleeve 1032 from completely passing through the sleeve through hole.

[0075] In summary, the built-in lifting module 1 and the self-lifting furniture provided in this embodiment have the following advantages:

[0076] ① By setting a built-in lifting module 1 in the side opening groove 201 of the furniture body 2, and utilizing the lifting function of the lifting direct drive mechanism 103, users can easily lift the furniture partially or entirely, making it easier for cleaning tools to enter the bottom space, thus solving the problems of traditional furniture being difficult to lift and inconvenient to clean.

[0077] ② Through the design of the decorative panel 1021 and the decorative panel connecting component 1022 of the decorative panel unit 102, the side opening is perfectly covered in the non-lifting normal state, maintaining the overall appearance and aesthetics of the furniture, and achieving a balance between functionality and aesthetics.

[0078] ③ By using detachable connection methods (such as magnetic attraction, buckle, etc.) to fix the decorative panel 1021, the standardized production of the core functional module of the lifting module and the flexible customization of the appearance decorative panel 1021 are separated, which significantly reduces the costs of procurement, production and inventory management.

[0079] ④ By adopting a sleeve direct drive mechanism 1033 consisting of a fixed sleeve 1031, a sliding sleeve 1032 and an accordion airbag 1033a, and controlling the expansion and contraction of the airbag through an inflation and deflation system 1033b, the furniture lifting and lowering can be smoothly driven, and the structure is simple and reliable.

[0080] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
