[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, the utility model provides a modular sofa, comprising two armrests 1 and at least one sofa body, the sofa body comprising a base 2, a seat cushion 3 and a backrest 4, at least three sides of the upper surface of the base 2 are provided with card slots 5, the inner sides of the sofa backrest 4 and the armrests 1 are fixed with snap fasteners 6 that match the card slots 5, and the seat cushion 3 is arranged on the upper surface of the base 2.

[0026] Similar to an ordinary sofa, two armrests 1 are arranged on the left and right sides of the modular sofa, and a backrest 4 is arranged behind the base 2 .

[0027] The structures of the two armrests 1 are exactly the same. When assembling the sofa, the armrests 1 on the seats on both sides of the sofa are the same and can be replaced with each other. At the same time, when there are multiple sets of sofa bodies, the structures of the multiple bases 2 are exactly the same, the structures of the multiple cushions 3 are exactly the same, and the structures of the multiple backrests 4 are also exactly the same. When assembling the sofa, the structures of the sofa bodies on both sides of the sofa and the sofa body in the middle are the same. There is no need to pay attention to the fixed position of the sofa bodies, and each sofa body is replaceable with each other.

[0028] The base 2 has three or four sides with slots 5, see Figure 3 When the four sides of the upper surface of the base 2 are provided with card slots 5, the shape of the sofa can be transformed into a single sofa, a multi-person sofa, an L-shaped sofa, a U-shaped sofa, etc.

[0029] Since the sofa backrest 4 and the armrest 1 are fixed to the sofa body by the same buckle 6, the same parts in the modular sofa can be replaced with each other, without a fixed order position, and the assembly is simpler, which effectively saves the production cost and labor cost of the manufacturer. At the same time, multiple modules are used to assemble the sofa, and the shape of the sofa can be changed according to the actual needs and preferences of the user, which is more personalized and meets the needs of many types of people.

[0030] refer to Figure 2 A back pillow 7 is also fixed on the backrest 4. The back pillow 7 includes a pillow body 701 and an anti-sliding block 702 extending from the bottom of the pillow body 701. The pillow body 701 contacts the upper surface of the backrest 4, and the anti-sliding block 702 contacts the upper surface of the seat cushion 3. The back pillow 7 and the backrest 4 are used in combination, and the back pillow 7 increases the height of the backrest 4, providing better support performance for the user's backrest.

[0031] Furthermore, the anti-sliding block 702 is in the shape of a right-angled triangular prism, one right-angled surface of the anti-sliding block 702 contacts the seat cushion 3, and the other right-angled surface contacts the surface of the backrest 4. When the user sits on the sofa, the backrest force is directed to the backrest 4, and the force is dispersed between the pillow body 701 and the anti-sliding block 702. On the one hand, under the restriction of the triangular prism-shaped anti-sliding block 702, the back pillow 7 will not slide or fall off, and on the other hand, the anti-sliding block 702 can fill the gap between the waist of the human body and the sofa, so that the support effect is better.

[0032] refer to Figure 6 A guide rod 8 is fixed below the pillow body 701, and a blind hole 9 for inserting the guide rod 8 is provided at the top of the backrest 4. When assembling the sofa, the guide rod 8 is aligned and inserted into the blind hole 9 to further enhance the stability of the connection between the back pillow 7 and the backrest 4.

[0033] Furthermore, the sofa body also includes a back cushion 10, the bottom of the back cushion 10 abuts against the seat cushion 3, and the back surface abuts against the back pillow 7. The back cushion 10 is supported by the seat cushion 3 and the back pillow 7, and the back cushion 10 can further enhance the comfort of leaning on the sofa.

[0034] Furthermore, the positions of the back cushion 10 and the seat cushion 3 are interchangeable.

[0035] refer to Figure 6 In the actual production process, in addition to the structure and size of the back cushion 10 and the seat cushion 3 being the same, the armrest 1 and the backrest 4 can also be processed into the same structure and size, that is, the back cushion 10 and the seat cushion 3 can be used interchangeably, and the armrest 1 and the backrest 4 can also be used interchangeably. Based on this, during production, only four component production lines, namely the base 2, the armrest 1, the seat cushion 3 and the backrest 7, need to be set up, and the manufacturer can produce the modular sofa, which makes the processing and production more streamlined, and effectively saves labor costs and production equipment costs.

[0036] refer to Figure 4 The fastener 6 includes a fixing portion 601 and an inserting portion 602 extending downward from the fixing portion 601 . The fixing portion 601 is fixed to the inner side of the sofa backrest 4 and the armrest 1 , and the inserting portion 602 is inserted into the card slot 5 .

[0037] Furthermore, a protruding block 603 extending outward is provided at the bottom end of the insertion portion 602. When the fastener 6 is inserted, the protruding block 603 and the insertion portion 602 are inserted into the card slot 5 together. When the insertion portion 602 is fully inserted into the card slot 5, the protruding block 603 abuts against the inner wall of the card slot 5 to increase the friction force. The insertion portion 602 will not move freely in the card slot 5, thereby ensuring the stability of the connection between the sofa backrest 4 and the base 2, and the armrest 1 and the base 2.

[0038] The fixing portion 601 , the inserting portion 602 and the protruding portion 603 are integrally formed.

[0039] Furthermore, at least two snap fasteners 6 are fixed to the inner side of each sofa backrest 4 and each armrest 1 , and the number of the slots 5 on the upper surface of the base 2 corresponds to the number of the snap fasteners 6 .

[0040] Furthermore, a detachable fixing piece is provided between two adjacent bases 2 , and the adjacent sofa bases 2 are connected by using a fixing piece with a U-shaped cross-section, so as to further enhance the connection performance between the multiple sofa bases 2 .

[0041] As a preferred solution, at least one base 2 in the modular sofa is an electric functional seat, and the calf position of the functional seat has an extension function. When the user sits on the electric functional seat, the calf position can be electrically lifted to achieve a semi-lying state. The extension component is a prior art and will not be described here.

[0042] The user can increase or decrease the number of sofa bases 2 and change the direction of the sofa base 2 according to their own needs, and adjust the sofa to a single sofa, a multi-person sofa, an L-shaped sofa, a U-shaped sofa and other different forms to meet different needs at different stages. Users can purchase corresponding sofa components to customize the sofa form that suits them. The assembly is convenient, and the components can be carried separately, which is more suitable for carrying spaces with size requirements such as stairs and elevators.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
