DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] In addition, in addition to being used to indicate the positions or location relationships, the above-mentioned terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. Those skilled in the art can understand the specific meanings of these terms in the present application according to the specific circumstances.

[0040] In addition, the terms "provided with", "provided with", "connected" should be understood broadly. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication between two devices, elements or components. Those skilled in the art can understand the specific meanings of the above-mentioned terms in the present application according to the specific circumstances.

[0041] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures can be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0042] In the field of sofas, as people's demand for home comfort and personalization continues to increase, modular sofas are increasingly favored by consumers. Modular sofas, with their flexible and versatile combination methods, can adapt to different living room spaces and layout requirements, creating a comfortable and unique home environment for people.

[0043] Modular sofas are usually composed of multiple independent modules, such as single-seater, double-seater, and three-seater, etc. The connection method between these modules is crucial. It not only relates to the overall stability and safety of the modular sofa, but also affects the comfort and aesthetics during use. If the connection is not stable, the sofa modules may shift or sway during daily use, not only affecting people's experience of sitting on the sofa, but also potentially causing damage to the sofa structure and shortening the service life of the sofa. Moreover, unreasonable connection methods can also lead to difficulties or time-consuming and labor-intensive problems in connecting the modular sofa.

[0044] Existing sofa connectors are usually male or female plugs installed on two sofas respectively, and the two adjacent sofas are connected by corresponding male and female plugs. However, only the sofa with a male plug can be combined with the sofa with a female plug, which greatly limits the combination method.

[0045] Based on this, the embodiments of the present application disclose a sofa connector and a modular sofa. The connector body is rotatably connected to the sofa through a first rotating shaft. The first connecting part of one sofa connector can be clamped with the second connecting part of another sofa connector, and the sofa with the sofa connector can be arbitrarily combined, making the installation between sofas more convenient.

[0046] The technical solutions of the present application will be further described below in conjunction with the embodiments and the accompanying drawings.

[0047] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the sofa connector 100 when the two clamping arms 41 of the embodiments disclosed by the present application are in the extended state. The sofa connector 100 disclosed by the embodiments of the present application comprises:

[0048] The connector body 1;

[0049] The first rotating shaft 2 is arranged on the connector body 1, and the first rotating shaft 2 is used for rotatably connecting with the sofa;

[0050] The first connecting part 3 is connected to the connector body 1;

[0051] The second connecting part 4 is connected to the connecting part body 1, and a preset included angle is formed between the first connecting part 3 and the second connecting part 4. The first connecting part 3 and the second connecting part 4 are matched in structure, so that the first connecting part 3 of one sofa connecting part 100 can be clamped with the second connecting part 4 of another sofa connecting part 100.

[0052] In this way, when connecting the sofas provided with the sofa connecting parts 100, the sofa connecting parts 100 can be flexibly rotated to adjust the installation angle, so that the first connecting part 3 of one sofa connecting part 100 can be clamped with the second connecting part 4 of another sofa connecting part 100, thereby reducing the installation difficulty and eliminating the need to select sofas provided with specific plugs for corresponding combination installation. In addition, the clamping mode is simple to operate, and ordinary users can easily complete the combination installation of the sofa without the help of complex tools or professional installation skills, thereby saving installation time and effort and improving installation efficiency.

[0053] Since the sofa connecting parts 100 can be combined at will, the sofa provided with the sofa connecting parts 100 has flexibility and adaptability. Users can adjust the combination mode of the sofa at any time according to different use scenarios and needs. Users can freely match the combination mode of the sofa according to their own preferences and home styles, and create a unique home environment. Users can combine the sofa into a simple straight line or into different shapes such as L-shaped and U-shaped.

[0054] As an optional implementation, in combination with Figure 1 The second connecting part 4 includes two clamping arms 41, the two clamping arms 41 are arranged at intervals along the first direction X and are movably connected to the connecting part body 1, so that the interval of the two clamping arms 41 in the first direction X is variable, and the two clamping arms 41 have a retracted state and an extended state.

[0055] The first connecting part 3 includes a first connecting part body, the first connecting part body includes oppositely arranged first and second end faces 311 and 312, the first end face 311 is arranged away from the first rotating shaft 2 relative to the second end face 312, the first connecting part body further includes a plug-in hole 313, the plug-in hole 313 penetrates the first and second end faces 311 and 312, and the maximum width of the second connecting part 4 along the first direction X is greater than the maximum width of the plug-in hole 313 perpendicular to the plug-in direction, so that the second connecting part 4 can be inserted into the plug-in hole 313.

[0056] The sofa connecting piece 100 further comprises a reset piece 5 connected between the connecting piece body 1 and the two clamping arms 41, so that when the second connecting part 4 is inserted into the insertion hole 313, the two clamping arms 41 can be extruded to the contracted state by the inner wall of the insertion hole 313, and the two clamping arms 41 can be reset to the extended state after the second connecting part 4 passes through the insertion hole 313, and the two clamping arms 41 are clamped with the second end surface 312 along the insertion direction.

[0057] This clamping structure enhances the stability of the connection between the two sofa connecting pieces 100. During the daily use of the sofa, the user's frequent sitting and lying activities will generate vibrations. Since the clamping arms 41 are tightly clamped with the second end surface 312 of the first connecting part 3 body, the loosening and falling off of the sofa connecting pieces 100 can be effectively prevented, ensuring the safety and stability of the sofa combination during use. This stable connection mode can ensure that the sofa combination always maintains a good connection state, avoiding the influence on the use experience and even causing safety hazards due to loose connection.

[0058] The cooperation mode of the two clamping arms 41 of the second connecting part 4 and the first connecting part 3 makes the connection operation of the sofa connecting piece 100 more convenient. When installing the sofa combination, the user only needs to insert the second connecting part 4 into the insertion hole 313 of the first connecting part 3. During the insertion process, the clamping arms 41 will automatically contract, and after passing through the insertion hole 313, they can automatically reset and clamp tightly. The whole process does not require additional tools and complex operation steps. Compared with some connection methods that require manual tightening of screws, nuts, etc., this design greatly saves installation time and effort. Even ordinary users without professional installation skills can easily complete the installation of the sofa combination, improving the user's experience.

[0059] In actual application, the styles and sizes of sofas are various. Through this adjustable connection structure, different specifications of sofa modules can be connected and combined through the connecting piece. Moreover, when the sofa combination needs to be adjusted or disassembled, the operation is relatively simple. Only the action force of the reset piece 5 is overcome to make the clamping arms 41 contract, and then the second connecting part 4 can be pulled out of the insertion hole 313, realizing the disassembly and recombination of the sofa module. This flexibility makes the sofa better adapt to different use scenarios and space layout changes, meeting the diversified needs of users.

[0060] In some embodiments, in combination Figure 1 and Figure 2 , Figure 2 Fig. 1 is a structural schematic diagram of a sofa connecting piece 100 according to an embodiment of the present application. The sofa connecting piece 100 comprises a connecting piece body 1 and a second connecting part 4. The second connecting part 4 is connected to the connecting piece body 1, and the second connecting part 4 comprises two clamping arms 41.

[0061] When the clamping arms 41 are inserted into the insertion holes 313, the clamping arms 41 are compressed and rotated to adapt to the angle to the retracted state, and after the two clamping arms 41 pass through the insertion holes 313, the clamping arms 41 are rotated to the extended state under the action of the reset member 5, and are clamped with the second end face 312 of the first connecting part 3 body. The connection between the two sofa connecting parts 100 is more firm, and the clamping arms 41 in the extended state can better cooperate with the inner wall of the insertion hole 313 and the second end face 312 of the first connecting part 3, forming a stable clamping structure, preventing accidental separation of the two connecting parts during use, and ensuring the overall stability of the sofa after combination, providing users with a more reliable use experience.

[0062] Since the clamping arms 41 are connected in a rotating manner, when a certain clamping arm 41 is damaged or fails, it only needs to be disassembled from the connecting part body 1 for replacement, without the need to replace the entire sofa connecting part 100, reducing maintenance cost and difficulty.

[0063] Optionally, in combination with Figure 1 and Figure 2 , the sofa connecting part 100 further comprises a second rotating shaft 6 and a third rotating shaft 7, the reset member 5 comprises a first reset member 51 and a second reset member 52, and the two clamping arms 41 are a first clamping arm 411 and a second clamping arm 412 respectively. The second rotating shaft 6 is connected between the connecting part body 1 and the first clamping arm 411, and the second rotating shaft 6 is connected to one end of the first clamping arm 411 away from the first rotating shaft 2, and the first reset member 51 is connected to one end of the first clamping arm 411 close to the first rotating shaft 2.

[0064] The third rotating shaft 7 is connected between the connecting part body 1 and the second clamping arm 412, and the third rotating shaft 7 is connected to one end of the second clamping arm 412 away from the first rotating shaft 2, and the second reset member 52 is connected to one end of the second clamping arm 412 close to the first rotating shaft 2.

[0065] When the two clamping arms 41 are inserted into the insertion hole 313, the first clamping arm 411 and the second clamping arm 412 are compressed by the inner wall of the insertion hole 313, and the end of the first clamping arm 411 close to the first rotating shaft 2 and the end of the second clamping arm 412 close to the first rotating shaft 2 are rotated inward to the retracted state around the second rotating shaft 6 and the third rotating shaft 7 respectively; when the two clamping arms 41 pass through the insertion hole 313, the first clamping arm 411 and the second clamping arm 412 are reset to the extended state under the action of the first reset member 51 and the second reset member 52 respectively, so that the end of the first clamping arm 411 close to the first rotating shaft 2 and the end of the second clamping arm 412 close to the first rotating shaft 2 are clamped with the second end face 312 of the first connecting part 3 body. The two clamping arms 41 can independently realize precise rotation control, and the two clamping arms 41 can be accurately adjusted in angle under the action of the respective rotating shafts according to the actual clamping requirements, so that the clamping process is more accurate and reliable, and the problem of mutual interference or motion incoordination between the two clamping arms 41 is avoided.

[0066] The rotating shafts provide stable support and rotation center for the rotation of the clamping arms 41, ensuring that the clamping arms 41 can maintain a smooth motion trajectory when switching between the retracted and extended states. During the clamping process, the clamping arms 41 can rotate around the rotating shafts according to the predetermined path, reducing shaking and deviation, thereby improving the accuracy and success rate of clamping and enhancing the stability of the sofa connecting part 100 during the connection process.

[0067] When the two clamping arms 41 are pressed to the retracted state, the first reset member 51 and the second reset member 52 can respectively apply a reset force to the first clamping arm 411 and the second clamping arm 412, ensuring that the clamping arms 41 can quickly and accurately reset to the extended state after the second connecting part 4 passes through the insertion hole 313, and realize reliable clamping with the second end face 312 of the first connecting part 3, greatly improving the reliability and stability of the reset.

[0068] In some embodiments, in combination Figure 4 , Figure 4 Another structural schematic diagram of the sofa connecting part 100 disclosed in the embodiments of the present application, the second rotating shaft 6 is connected to the end of the first clamping arm 411 close to the first rotating shaft 2, and the first reset member 51 is connected to the end of the first clamping arm 411 away from the first rotating shaft 2; the third rotating shaft 7 is connected to the end of the second clamping arm 412 close to the first rotating shaft 2, and the second reset member 52 is connected to the end of the second clamping arm 412 away from the first rotating shaft 2.

[0069] When the two clamping arms 41 are inserted into the insertion hole 313, the first clamping arm 411 and the second clamping arm 412 are compressed by the inner wall of the insertion hole 313, and the end of the first clamping arm 411 away from the first rotating shaft 2 and the end of the second clamping arm 412 away from the first rotating shaft 2 are rotated inwardly to the contracted state around the second rotating shaft 6 and the third rotating shaft 7 respectively; when the two clamping arms 41 pass through the insertion hole 313, the first clamping arm 411 and the second clamping arm 412 are reset to the extended state under the action of the first reset member 51 and the second reset member 52 respectively, so that the side of the first clamping arm 411 and the second clamping arm 412 close to the second end face 312 is clamped with the second end face 312.

[0070] As an optional embodiment, the reset member 5 is a spring, and extends along the first direction X.

[0071] The spring has good elastic performance and can quickly recover to the original shape after deformation under stress, thereby providing stable and reliable reset force for the clamping arm 41. When the clamping arm 41 of the second connecting part 4 is inserted into the insertion hole 313 of the first connecting part 3, the spring is deformed by extrusion, so that the clamping arm 41 is in the contracted state; and after the second connecting part 4 passes through the insertion hole 313, the spring can immediately release the elastic force to quickly reset the clamping arm 41 to the extended state, so as to realize the clamping with the second end face 312 and ensure the stability of the connection.

[0072] The spring extends along the first direction X, which can better adapt to the movement and stress characteristics of the clamping arm 41 in the first direction X. During the use of the sofa, the spring extending along the first direction X can provide more direct and effective reset force in this direction, so that the clamping of the two clamping arms 41 with the second end face 312 is more closely, and the stability and reliability of the sofa connecting part 100 are enhanced.

[0073] In some embodiments, the preset included angle is 180°. In this way, when the first connecting part 3 or the second connecting part 4 is called, the connecting part body 1 only needs to be rotated by 180° each time, so that the connection from using one connecting part to using another connecting part can be quickly switched. This greatly reduces the difficulty and complexity of the operation, and the user can easily complete the connection and combination of the sofa, saving time and effort.

[0074] In some possible embodiments, in combination with Figure 1 and Figure 2 , the sofa connecting part 100 further comprises a guide part 8, which is arranged on the connecting part body 1 and located on the side of the second connecting part 4 away from the first rotating shaft 2.

[0075] In the direction close to the first rotating shaft 2, the distance between the two clamping arms 41 along the first direction X gradually increases;

[0076] In the first direction X, the minimum distance between the two clamping arms 41 is less than the maximum width of the insertion hole 313 perpendicular to the insertion direction, and the maximum distance between the two clamping arms 41 is greater than the maximum width of the insertion hole 313 perpendicular to the insertion direction. This design allows the clamping arms 41 to smoothly enter the insertion hole 313 when inserted, because the minimum distance is less than the width of the insertion hole 313. When the clamping arms 41 pass through the insertion hole 313, they can return to the extended state under the action of the reset member 5 and be clamped with the second end surface 312 of the first connecting part 3 along the insertion direction, forming a firm connection and preventing the two sofa connecting parts 100 from accidentally separating, ensuring the stability of the sofa combination.

[0077] In the first direction X, the maximum width of the guide part 8 is greater than the minimum distance between the two clamping arms 41 and less than the maximum width of the insertion hole 313 perpendicular to the insertion direction.

[0078] The guide part 8 can play a guiding role, which can help users more accurately align the second connecting part 4 with the insertion hole 313. Especially when the two sofa connecting parts 100 are not completely aligned, the guide part 8 can make the second connecting part 4 more smoothly approach the insertion hole 313, reducing the difficulty and time of alignment and improving the efficiency of clamping operation.

[0079] Optionally, in combination with Figure 1 and Figure 2 , the sofa connecting part 100 further comprises a positioning assembly 9, which is arranged between the first rotating shaft 2 and the connecting part body 1. When the connecting part body 1 is rotated to a preset angle, the positioning assembly 9 can position the connecting part body 1 and the first rotating shaft 2.

[0080] The presence of the positioning assembly 9 allows the sofa connecting part 100 to be positioned after being rotated to a preset angle. The sofa can be adjusted to different angles according to the actual needs of the user and fixed, and will not easily rotate due to external forces. The structure of the entire sofa is more stable, the connection between the various components of the sofa is more tight, the overall structural strength of the sofa is enhanced, and the service life of the sofa is prolonged.

[0081] As an optional embodiment, in combination with Figures 1 to 3 , Figure 3 is a structural schematic view of the sofa connecting part 100 from another perspective disclosed in the embodiments of the present application. The positioning assembly 9 comprises a ratchet wheel 91, a pawl 92 and an elastic member 93. The ratchet wheel 91 is arranged on the first rotating shaft 2, the pawl 92 is rotationally connected to the connecting part body 1 and abuts against the ratchet wheel 91, and the elastic member 93 is connected between the pawl 92 and the connecting part body 1. When the connecting part body 1 rotates in the first rotation direction Y, the elastic member 93 can exert a damping force on the connecting part body 1 in the first rotation direction Y.

[0082] When the connecting body 1 rotates, the pawl 92 is always in abutment with the ratchet wheel 91 under the action of the elastic member 93. The ratchet wheel 91 has a series of teeth, and the pawl 92 can be clamped into these teeth, so that the connecting body 1 can be accurately positioned when rotated to a certain angle. During the use of the sofa, the user can adjust the sofa to the appropriate angle according to the needs, and the pawl 92 is clamped into the corresponding tooth groove of the ratchet wheel 91, which ensures that the sofa is stably maintained at this angle. Since the ratchet wheel 91 has multiple teeth, it means that the connecting body 1 can be positioned at multiple preset angles. The user can choose different angles according to the actual situation to achieve diversified adjustment of the sofa angle, improving the flexibility and adaptability of the sofa.

[0083] When the user applies a force greater than the damping force to rotate the connecting body 1, the connecting body 1 will rotate, which can prevent the sofa from accidentally rotating due to external forces (such as collision, shaking, etc. of personnel), ensuring the stability of the sofa angle and improving the safety of the sofa use.

[0084] The cooperation of the pawl 92 and the ratchet wheel 91 usually has the characteristics of one-way rotation, and the connecting body 1 can rotate smoothly and be positioned in the first rotation direction Y, while it cannot rotate in the opposite direction, ensuring the stability of the structure.

[0085] In a second aspect, in combination with any one of the sofa connecting pieces 100 of the first aspect, Figure 5 The sofa connecting piece 100 can be combined with any sofa body 10, and the sofa body 10 can be combined with any sofa connecting piece 100, so that the sofa connecting piece 100 can be combined with any sofa body 10, and the sofa body 10 can be combined with any sofa connecting piece 100.
