[0031] In recent years, with the rapid development of the economy, people's pursuit of the quality of life is constantly improving. For household sofas, consumers are no longer limited to simply satisfying the single sitting posture function. Instead, they hope to obtain more functional experiences without affecting the family space. Thus, a new type of multifunctional sofa with a series of additional functions such as posture adjustment, shape transformation, storage, and massage and health care has emerged.

[0032] Sofas with storage functions are favored by small-sized families and can effectively save the occupation of family space. For example, a storage space is provided inside the sofa armrest, and the armrest panel can be opened as a cover for storage.

[0033] However, in related technologies, the opening method of the armrest cover plate is mostly to install a connecting piece on the side of the armrest cover plate, and set a handle or a buckle on the armrest cover plate so that the armrest panel can be opened, or directly disassemble the armrest panel. In this way, on the one hand, the opening method of the armrest panel is complex, which directly affects the user experience, and on the other hand, it affects the aesthetics of the armrest appearance.

[0034] In view of this, the embodiment of the present application discloses a sofa with a liftable armrest panel. By arranging a lifting assembly in a storage cavity with an upward opening formed by the armrest structure and connecting it to the armrest panel, the lifting assembly is configured to drive the armrest panel to rise to expose the opening of the storage cavity. This helps to improve the simplicity of opening the armrest panel and the user experience. On the other hand, the armrest panel can rotate relative to the lifting rod through a rotating member, and can move relative to the armrest main body along a first direction through a slide rail portion and a sliding portion, so that the armrest panel can be used as a separate table board flexibly, and its position, height and angle can be adjusted during use. In addition, a partition is arranged in the storage cavity to divide the storage cavity into a first sub-cavity and a second sub-cavity. The lifting assembly is arranged in the second sub-cavity, and the volume of the second sub-cavity is smaller than that of the first sub-cavity, so that the first sub-cavity can store items without interfering with the lifting assembly, which helps to improve the user experience.

[0035] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0036] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the sofa structure in the state where the armrest panel is raised disclosed in the embodiment of the present application. The sofa 100 with a liftable armrest panel 12 includes a sofa main body 2 and an armrest structure 1. The armrest structure 1 is arranged on one side of the sofa main body 2. The armrest structure 1 includes an armrest main body 11, a lifting assembly 13 and an armrest panel 12. The armrest main body 11 forms a storage cavity 111 with an upward opening. The armrest panel 12 is arranged on the armrest main body 11. When the armrest panel 12 is in the non-raised state, the armrest panel 12 covers the armrest main body 11 to block the opening of the storage cavity 111. The lifting assembly 13 is located in the storage cavity 111. The lifting assembly 13 is connected to the armrest main body 11 and the armrest panel 12. The lifting assembly 13 is configured to drive the armrest panel 12 to rise relative to the armrest main body 11 to expose the opening of the storage cavity 111.

[0037] First of all, by setting the lifting assembly 13 to drive the armrest panel 12 to rise relative to the armrest main body 11 and expose the opening of the storage cavity 111, it helps to make reasonable use of the internal space of the armrest main body 11 for storage and increases the functionality of the sofa 100.

[0038] In addition, the armrest panel 12 can be directly raised relative to the armrest main body 11 through the lifting assembly 13 without disassembling the armrest panel 12, which helps to improve the convenience of opening the armrest panel 12 and thus helps to improve the user experience.

[0039] In some embodiments, referring to Figure 1 , the above-mentioned sofa main body 2 includes a seat portion 3 and a backrest portion 4, and the armrest main body 11 extends from the backrest portion 4 to the seat portion 3. A partition 111a is provided in the storage cavity 111. The partition 111a is arranged along the height direction of the storage cavity 111. The partition 111a divides the storage cavity 111 into a first sub-cavity 111b and a second sub-cavity 111c arranged in sequence from the backrest portion 4 to the seat portion 3. The lifting assembly 13 is arranged in the second sub-cavity 111c. By providing the partition 111a, the storage cavity 111 is divided into two sub-cavities, and the lifting assembly 13 is arranged in the sub-cavity far from the backrest portion 4, which helps to avoid interference with the lifting assembly 13 during storage and thus ensures the normal operation of the lifting assembly 13.

[0040] Optionally, referring to Figure 1 , the volume of the above-mentioned second sub-cavity 111c is smaller than the volume of the first sub-cavity 111b. With this setting method, while ensuring the normal use of the lifting assembly 13, the volume of the first sub-cavity 111b is made as large as possible, which helps to increase the storage space and can accommodate more items.

[0041] Optionally, referring to Figure 2 , Figure 2It is a structural diagram of the armrest panel and the interior of the storage cavity disclosed in the embodiments of the present application. The above-mentioned lifting assembly 13 includes a lifting rod 131 and an elastic member 133. The lifting rod 131 is disposed below the armrest panel 12. The lower end of the lifting rod 131 is connected to the lower bottom surface of the storage cavity 111, and the upper end of the lifting rod 131 is connected to the lower surface of the armrest panel 12 to support the armrest panel 12. The lifting rod 131 is configured to drive the armrest panel 12 to rise relative to the armrest main body 11. The elastic member 133 is disposed inside one end of the lifting rod 131 away from the armrest panel 12, and the elastic member 133 is configured to provide a force for the lifting rod 131 to reset. Through the cooperation of the lifting rod 131 and the elastic member 133, the user can press the position of the armrest panel 12 corresponding to the lifting rod 131 to make the armrest panel 12 rise relative to the armrest main body 11 to expose the opening of the storage cavity 111. After storing items, the user can press the position of the armrest panel 12 corresponding to the lifting rod 131 again to make the armrest panel 12 fall relative to the armrest main body 11 to cover the opening of the storage cavity 111. This helps to open the storage cavity 111 to put items into the storage cavity 111 to achieve the storage function, and after storing, the opening can also be covered, which helps to prevent external dust, etc. from entering the storage cavity 111 and contaminating the items in the storage cavity 111, and further helps to keep the items in the storage cavity 111 clean.

[0042] It can be understood that the above-mentioned elastic member 133 is preferably a bouncer, which can be a mechanical bouncer or a pneumatic bouncer. The mechanical bouncer has better stability and longer service life, which helps to improve the service life of the elastic member 133, and further helps to improve the service life of the entire sofa 100. The pneumatic bouncer is more labor-saving, makes less noise, and is more smooth in use, which helps to improve the smoothness of the elastic member 133 in use and reduce the volume generated during the use of the elastic member 133, and further helps to improve the user's comfort. This embodiment does not make specific limitations on this.

[0043] In some embodiments, please refer to Figure 2 , the above-mentioned lifting rod 131 includes a first rod body 1311 and a second rod body 1312. One end of the first rod body 1311 is connected to the armrest main body 11, and the second rod body 1312 is telescopically connected to the other end of the first rod body 1311, and the second rod body 1312 is connected to the armrest panel 12. The first rod body 1311 and the second rod body 1312 are telescopically connected, which helps to further adjust the height of the armrest panel 12 when the armrest panel 12 rises relative to the armrest main body 11, helps to place items of different sizes into the storage cavity 111, and further helps to improve the user experience.

[0044] Optionally, please refer to Figure 2, a first retaining portion 1311a is provided on the first rod body 1311, and a plurality of second retaining portions 1312a are provided on the second rod body 1312. The plurality of second retaining portions 1312a are arranged at intervals along the length direction of the second rod body 1312. The first retaining portion 1311a is configured to be connected to one of the plurality of second retaining portions 1312a so that the second rod body 1312 is held relative to the first rod body 1311 at the current telescopic height. This helps to improve the stability after the telescopic heights of the first rod body 1311 and the second rod body 1312 are fixed.

[0045] It can be understood that the materials of the first rod body 1311 and the second rod body 1312 can be metal, aluminum alloy, carbon steel, stainless steel or carbon fiber. The first rod body 1311 and the second rod body 1312 made of metal materials have high durability and load-bearing capacity, which helps to improve the stability of the first rod body 1311 and the second rod body 1312, and thus helps to improve the stability of the armrest panel 12, and also helps to extend the service life of the first rod body 1311 and the second rod body 1312. The first rod body 1311 and the second rod body 1312 made of aluminum alloy materials are light and durable, which helps to reduce the overall weight of the armrest structure 1 and is convenient for handling. The first rod body 1311 and the second rod body 1312 made of carbon steel materials have good stability and durability, which helps to improve the stability of the armrest panel 12 and also helps to save maintenance costs. The first rod body 1311 and the second rod body 1312 made of stainless steel materials have corrosion resistance, which helps to extend the service life of the first rod body 1311 and the second rod body 1312. The first rod body 1311 and the second rod body 1312 made of carbon fiber materials are light in weight and high in strength, which helps to reduce the weight of the armrest structure 1 while maintaining the strength of the first rod body 1311 and the second rod body 1312. In this embodiment, the materials of the first rod body 1311 and the second rod body 1312 are not specifically limited.

[0046] It can be understood that, please refer to Figure 2 , the first retaining portion 1311a can be an elastic convex portion, and the corresponding second retaining portion 1312a can be a positioning hole, and the positioning hole can achieve clamping of the elastic convex portion so that the first rod body 1311 and the second rod body 1312 maintain their heights during the telescopic process. Of course, as another example, it can also be the other way around, the first retaining portion 1311a is a positioning hole, and the second retaining portion 1312a is an elastic convex portion.

[0047] In another example, please refer to Figure 2, the above-mentioned second holding part 1312a can be provided in multiple numbers not only along the length direction of the second rod body 1312, but also at intervals along the central axis of the second rod body 1312. Correspondingly, a plurality of first holding parts 1311a are provided at intervals along the central axis of the first rod body 1311. This setting method helps to improve the support of the first rod body 1311 for the second rod body 1312, and further helps to improve the stability of maintaining the telescopic height during the telescopic process of the first rod body 1311 and the second rod body 1312.

[0048] It can be understood that, please refer to Figure 2 , there are various embodiments for setting the above-mentioned second holding part 1312a on the second rod body 1312. It can be integrally formed or separately formed and then connected. Taking the integral forming as an example, the second holding part 1312a and the second rod body 1312 are integrally formed, which helps to reduce the process of connecting the second holding part 1312a to the second rod body 1312. On the other hand, the integral forming of the two helps to improve the rigidity of the second rod body 1312 and make the stability better. Taking the separate forming and then connecting as an example, the separate connection helps to improve the setting flexibility of the second holding part 1312a and also helps to improve the convenience of replacing the second holding part 1312a. This embodiment does not make specific limitations on this.

[0049] It can be understood that, please refer to Figure 2 , the setting of the above-mentioned first holding part 1311a and the second holding part 1312a is based on the raising of the armrest panel 12, and further enables the first rod body 1311 to be adjusted up and down relative to the second rod body 1312, and its telescopic height can be fixedly maintained, which helps to flexibly adjust the height of the position of the armrest panel 12 according to the user's usage requirements.

[0050] In some embodiments, please refer to Figure 2 , the sofa 100 with a liftable armrest panel 12 further includes a rotating member 132. The rotating member 132 is arranged below the armrest panel 12. The upper end of the rotating member 132 is fixedly connected to the armrest panel 12, and the lower end of the rotating member 132 is sleeved on the upper end of the second rod body 1312, so that the second rod body 1312 is rotatably connected to the rotating member 132. Furthermore, when the armrest panel 12 rises relative to the armrest main body 11, the armrest panel 12 can rotate relative to the second rod body 1312. This helps to improve the usage flexibility of the armrest panel 12 and further helps to meet the different usage requirements of users.

[0051] Optionally, please refer to Figure 3 , Figure 3It is a schematic diagram of a sofa structure in the rotating state of the armrest panel disclosed in the embodiments of the present application. When the armrest panel 12 rotates relative to the second rod 1312 to a position extending along the width direction of the seat portion 3 of the sofa main body 2, the armrest panel 12 can be used as a separate table board to meet the needs of users to place items such as computers and water cups. The armrest panel 12 can be used as a separate table board, which on the one hand helps to increase the versatility of the sofa 100, and on the other hand, the armrest panel 12 can replace the function of the coffee table, thereby reducing the space occupied by setting up a separate coffee table.

[0052] It can be understood that the material of the above-mentioned armrest panel 12 should be a material with a certain hardness and support to meet the needs of placing items on the armrest panel 12. Optionally, the material of the armrest panel 12 can be wood, metal, plastic or acrylic. Using wood as the material of the armrest panel 12 has good plasticity and durability, which helps to improve the service life. Using metal as the material of the armrest panel 12 has good load-bearing capacity and corrosion resistance, which helps to improve the durability of the armrest panel 12. Using plastic as the material of the armrest panel 12 helps to reduce the weight of the armrest panel 12, is easier to process, and helps to improve the economy of the armrest panel 12. Using acrylic as the material of the armrest panel 12 helps to improve the wear resistance and aesthetics of the armrest panel 12. This embodiment does not make specific limitations on this.

[0053] It can be understood that the above-mentioned armrest panel 12 can be used alone as a table board for placing items, so the armrest panel 12 should also have a certain width and the surface of the armrest panel 12 is flat.

[0054] It can be understood that there can be multiple embodiments for the connection method between the above-mentioned rotating member 132 and the armrest panel 12. The rotating member 132 and the armrest panel 12 can be integrally formed, or the rotating member 132 and the armrest panel 12 can be separately formed and then fixedly connected. Taking the rotating member 132 and the armrest panel 12 being integrally formed as an example, it helps to improve the connection stability between the rotating member 132 and the armrest panel 12, and further helps to improve the stability of the armrest panel 12 during use. In addition, integral forming also helps to save the installation steps between the rotating member 132 and the armrest panel 12. Taking the rotating member 132 and the armrest panel 12 being separately formed and then fixedly connected as an example, it helps to improve the connection flexibility between the rotating member 132 and the armrest panel 12, and helps to adjust the size or connection method of the rotating member 132 and the armrest panel 12 at any time during the installation process. This embodiment does not make specific limitations on this.

[0055] In some embodiments, please refer to Figure 2 and Figure 3, a plurality of first limiting portions 1321 are provided on the rotating member 132. The plurality of first limiting portions 1321 are arranged at intervals along the central axis of the rotating member 132. Correspondingly, a plurality of second limiting portions 1312b are provided on the lifting rod 131. The plurality of first limiting portions 1321 and the plurality of second limiting portions 1312b are correspondingly connected, so that when the armrest panel 12 rotates relative to the second rod body 1312, the armrest panel 12 can maintain its rotation angle. This helps the user to fix the armrest panel 12 at the desired position at the desired angle when rotating the armrest panel 12, thereby helping to improve the stability of the armrest panel 12 after rotation and fixation.

[0056] Optionally, please refer to Figure 2 and Figure 3 , the above-mentioned first limiting portion 1321 can be a limiting hole, and the corresponding second limiting portion 1312b can be an elastic limiting block. The limiting hole can be clamped with the elastic limiting block to realize that the rotation angle of the armrest panel 12 can be maintained at the position where the elastic limiting block is arranged during the rotation process of the armrest panel 12. This helps to improve the rotation flexibility of the armrest panel 12 and also helps to improve the stability of the armrest panel 12 after rotation and fixation. Of course, as other examples, it can also be the other way around, the above-mentioned first limiting portion 1321 is an elastic limiting block, and the above-mentioned second limiting portion 1312b is a limiting hole.

[0057] It can be understood that, please refer to Figure 2 and Figure 3 , to enable the armrest panel 12 to rotate at multiple angles relative to the second rod body 1312 and be fixed at multiple angles, the above-mentioned plurality of limiting holes have the same size, the plurality of elastic limiting blocks also have the same size, and the number of the plurality of limiting holes is the same as that of the plurality of elastic limiting blocks, so as to realize that the plurality of limiting holes can respectively clamp the plurality of elastic limiting blocks, so that the armrest panel 12 can be fixed at multiple angles during the rotation process, which helps to meet the user's needs for fixing the armrest panel 12 at different angles, and thus helps to improve the user experience.

[0058] Optionally, the materials of the above-mentioned elastic protrusions and elastic limit blocks can be carbon steel, alloy steel, stainless steel, copper, aluminum alloy or elastic alloy. The elastic protrusions and elastic limit blocks made of carbon steel material have good hardness and elasticity, which helps to improve the smoothness of use of the elastic protrusions and elastic limit blocks. The elastic protrusions and elastic limit blocks made of alloy steel material have good strength and ductility, which helps to improve the service life of the elastic protrusions and elastic limit blocks. The elastic protrusions and elastic limit blocks made of copper material are soft and easy to process, which helps to keep the original shape of the elastic protrusions and elastic limit blocks during use, and thus helps to improve the service life. The elastic protrusions and elastic limit blocks made of aluminum alloy material are light in weight and high in strength, which helps to reduce their weight while maintaining the high strength of the elastic protrusions and elastic limit blocks, and thus helps to reduce the weight of the armrest structure 1 and facilitate handling. The elastic protrusions and elastic limit blocks made of elastic alloy material have good resilience and can still maintain good elastic performance after multiple uses, which helps to improve the service life of the elastic protrusions and elastic limit blocks. This embodiment does not make specific limitations on this.
