[0029] Refer to Figures 1-3 A horizontal rhythm sofa, comprising: a rhythm base mechanism 1, a cushion support mechanism 2, a back support mechanism 3 and a linkage mechanism;

[0030] The cushion support mechanism 2 includes a cushion support 21 and a first drive assembly, the cushion support 21 is arranged on the rhythm base mechanism 1, and the first drive assembly is used to drive the cushion support 21 to move horizontally and linearly to the side close to or away from the back support mechanism 3;

[0031] The back support mechanism 3 includes a back support 31 and two connecting sheet metals 32 arranged on the bottom of the back support 31 on both sides, and the top end side of the connecting sheet metal 32 is rotationally connected with the cushion support 21;

[0032] The linkage mechanism comprises a first connecting rod 4, a second connecting rod 5 and a third connecting rod 6, the middle part of the first connecting rod 4 is rotatably arranged on one side of the cushion support 21, one end of the second connecting rod 5 is connected with the top end of the first connecting rod 4, the other end is connected with the bottom end of the connecting sheet metal 32, and the included angle between the second connecting rod 5 and the first connecting rod 4 is downward; one end of the third connecting rod 6 is connected with the bottom end of the first connecting rod 4, the included angle between the third connecting rod 6 and the first connecting rod 4 is toward one side of the back support 31, and the other end is connected with the rhythmic base mechanism 1, wherein the rotation axes of the first connecting rod 4, the second connecting rod 5 and the third connecting rod 6 are parallel and all point to the horizontal direction; and in order to improve the synchronization of the movement of the two sides of the back support, two linkage mechanisms are arranged, and the two linkage mechanisms are arranged on the two sides of the cushion support 21.

[0033] Based on the above structure, when in use, the user sits on the cushion on the cushion support 21 and leans against the back support 31, at this time, the user is in a sitting position; when it is necessary to change the angle of the back support 31, the first driving assembly drives the cushion support 21 to move horizontally and linearly away from the back support 31, so that the cushion support 21 and the back support 31 are linked through the first connecting rod 4, the second connecting rod 5 and the third connecting rod 6, specifically: when the cushion support 21 moves away from the back support 31, the first connecting rod 4 rotates (the included angle between the first connecting rod 4 and the horizontal plane gradually increases), so that the second connecting rod 5 moves away from the back support 31, and then the connecting sheet metal 32 rotates (the bottom of the connecting sheet metal 32 moves toward one side of the back support 31), so that the back support 31 is gradually flattened (the included angle between the back support 31 and the horizontal plane decreases), therefore, when the cushion support 21 moves away from the back support 31, the back support 31 is flattened synchronously, so that the cushion support 21 and the back support 31 tend to be on the same horizontal plane, and the user can lie flat on the sofa, thereby further increasing the diversity of the functions of the application and providing the user with a more rich use experience.

[0034] As shown in Figure 1 and Figure 2 , one side of the cushion support 21 is provided with two limiting sheet metals 7, the limiting sheet metals 7 are provided with arc-shaped limiting holes, the middle part of the connecting sheet metal 32 is provided with limiting rods, and the two limiting rods are slidingly arranged in the two limiting holes, so that the limiting sheet metal 7 can only move under the limitation of the limiting hole, thereby ensuring that the back support 31 operates more stably.

[0035] As shown in Figure 4 and Figure 5As shown, the rhythm base mechanism 1 comprises a base 11, a rhythm support 12 arranged on the base 11, and a second driving assembly 13 for driving the rhythm support 12 to move horizontally on the base 11; one end of the third connecting rod 6 away from the first connecting rod 4 is connected with the rhythm support 12 (the specific structure and driving mode of the second driving assembly 13 are prior art, which is not described in detail here), so that, in use, the second driving assembly 13 can drive the rhythm support 12 to move horizontally, thereby enabling the user sitting on the cushion support 21 to move horizontally together; and the base 11 is provided with a plurality of limiting assemblies, each of which comprises a limiting block 14 and a plurality of bearings 15, the limiting block 14 is horizontally provided with a limiting channel 16, the rhythm support 12 is arranged in the limiting channel 16, and the plurality of bearings 15 are arranged at the top, bottom and two sides of the limiting block 14 respectively, and the ring side of each bearing 15 extends into the limiting channel 16; in this embodiment, the plurality of limiting assemblies are arranged at the top of the base 11, and the two sides of the rhythm support 12 are arranged in the limiting channels 16 on the two sides; when the second driving assembly 13 drives the rhythm support 12 to move back and forth, the rhythm support 12 does not directly contact the limiting block 14, but rolls in contact with the bearings 15 (the bearings 15 can be rubber-coated bearings), so that the rhythm support 12 moves more smoothly and with lower noise.

[0036] As shown in Figure 4 The rhythm support 12 is provided with a buffer assembly 8 on each side in the movement direction of the cushion support 21, the buffer assembly 8 is a spring, a spring piece or a rubber column, and buffers and slows down the movement of the cushion support 21 to reduce the impact damage to the first driving assembly.

[0037] As shown in Figure 2 In order to drive the cushion support 21 to move, the first driving assembly specifically comprises a push rod 22 (the push rod 22 can be an electric push rod or the like), which is horizontally arranged on the rhythm support 12, and the driving end of the push rod 22 is connected with the cushion support 21, so that the push rod 22 is stretched and retracted to drive the cushion support 21 to move horizontally.

[0038] In summary: when in use, the user sits on the cushion on the cushion support 21 and leans against the backrest support 31, at this time, the user is in a sitting position; when the angle of the backrest support 31 needs to be changed, the first driving assembly drives the cushion support 21 to move horizontally and linearly away from the side of the backrest support 31, thus, the cushion support 21 and the backrest support 31 are linked through the first connecting rod 4, the second connecting rod 5 and the third connecting rod 6, specifically: when the cushion support 21 moves away from the side of the backrest support 31, the first connecting rod 4 rotates, the second connecting rod 5 moves away from the side of the backrest support 31, and the connecting plate 32 rotates, so that the backrest support 31 is gradually flattened, therefore, when the cushion support 21 moves away from the side of the backrest support 31, the backrest support 31 is flattened synchronously, the cushion support 21 and the backrest support 31 tend to be in the same horizontal plane, and the user can lie flat on the sofa; the function diversity of the application is further increased, and the user has a more abundant use experience.

[0039] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model, and those skilled in the art can make modifications without creative contribution according to the needs after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, the utility model is protected by the patent law.
