Description

Technical Field

[0001] The utility model relates to the field of sofas, in particular to a flat-pushing sofa structure. Background Art

[0002] A sofa is a chair with an elastic cushion. Existing sofa beds generally use horizontal guide rails in combination with curved guide rails to achieve the sliding of the footrest, thereby switching the sofa to a bed. However, in actual design, because the guide rail and the curved guide rail are integrated, there is a joint end during the actual sliding process. When the reciprocating movement and the supporting force are large, it is easy to cause wear of the guide rail and the slider structure, thereby affecting the stability and safety of the sofa bed. Utility Model Content

[0003] The main purpose of the utility model is to propose a flat-push sofa structure, aiming to improve the structure of the existing flat-push sofa, thereby ensuring the stability of the sofa bed, and at the same time providing a more stable support force and smoother sliding.

[0004] To achieve the above purpose, the utility model provides a flat-push sofa structure, comprising:

[0005] A chassis, wherein the chassis is provided with a plurality of guide rods arranged transversely, the guide rods are provided with guide sleeves arranged slidably, at least one set of driving devices is arranged between the guide rods, and the driving device comprises a driving rod arranged on the chassis and a driving assembly arranged on the driving rod;

[0006] The cushion seat is slidably mounted on the base frame and connected with the guide sleeve and the driving assembly. The driving assembly can drive the rear part of the cushion seat to slide between a position extending into the backrest seat and a position extending out of the backrest seat.

[0007] In the actual design, the rear part of the cushion is extended into the lower wall of the backrest and then hidden. At this time, the sofa as a whole is a sofa. When the user needs to extend the length of the sofa cushion for greater comfort, the cushion is driven by the driving component to slide along the length direction of the guide rod and extend a predetermined length. The length of the cushion can be extended to become a sofa bed. Compared with the existing sliding sofas, its structure is simpler, more stable, and has better support. At the same time, it has better integrity and stability. Compared with the existing sofas, it is differentiated and effectively improved in market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 3 As shown, a push-flat sofa structure includes:

[0020] A base frame 1, wherein the base frame 1 is provided with a plurality of guide rods 11 arranged transversely, the guide rods 11 are provided with guide sleeves 12 arranged slidably, at least one set of driving devices is provided between the guide rods 11, and the driving device includes a driving rod 2 arranged on the base frame 1 and a driving assembly arranged on the driving rod 2;

[0021] The cushion seat 3 is slidably mounted on the base frame 1 and connected to the guide sleeve 12 and a driving assembly. The driving assembly can drive the rear portion of the cushion seat 3 to slide between a position extending into the backrest seat 30 and a position extending out of the backrest seat 30.

[0022] In the actual design, the rear part of the cushion is extended into the lower wall of the backrest and then hidden. At this time, the sofa as a whole is a sofa. When the user needs to extend the length of the sofa cushion for greater comfort, the cushion is driven by the driving component to slide along the length direction of the guide rod and extend a predetermined length. The length of the cushion can be extended to become a sofa bed. Compared with the existing sliding sofas, its structure is simpler, more stable, and has better support. At the same time, it has better integrity and stability. Compared with the existing sofas, it is differentiated and effectively improved in market competitiveness.

[0023] Specifically, a bearing 13 is provided between the guide sleeve 12 and the guide rod 11 , and the bearing 13 is fixed in the guide sleeve 12 .

[0024] More specifically, the guide sleeve 12 and the bearing 13 are integrated into a universal fisheye bearing rod, the universal fisheye bearing rod is provided with a screw rod 14 extending upward, and the cushion seat 3 is fixed by the screw rod 14. The advantage of using the universal fisheye bearing rod is that it slides more smoothly, can reduce abnormal noise, has better supporting force, and is more stable in combination.

[0025] In the embodiment of the utility model, the guide rod 11 is a cylindrical guide rod 11. Of course, a square shape can also be used, but from the perspective of sliding, the guide rod 11 and the guide sleeve 12 adopt a circular structure, and the corresponding supporting force distribution is more uniform, which effectively improves the stability of sliding.

[0026] Specifically, the guide sleeves 12 are provided in at least two groups, thereby ensuring the support and sliding stability of the pad body.

[0027] In the embodiment of the utility model, the driving assembly includes a ball screw disposed in the cavity of the driving rod 2, a screw nut slidably mounted on the ball screw, and a rotary motor 21 for driving the ball screw to rotate, and the screw nut extends out of both sides of the driving rod 2 and is connected to the lower wall of the cushion body. That is, the ball screw rotates to drive the screw nut to slide horizontally, thereby driving the automatic sliding of the cushion body, which facilitates the use of the sofa and pushes it horizontally, and its driving noise is smaller.

[0028] In practice, guide grooves 23 are provided on both sides of the driving rod, and a slide seat 24 is connected to the screw nut, and the slide seat can slide along the guide grooves.

[0029] Specifically, L-shaped corner brackets 22 are provided on both sides of the screw nut and connected to the bottom wall of the pad body, thereby facilitating the assembly of the pad body.

[0030] In the embodiment of the utility model, the driving rod 2 is in a flat structure, so that the pad body and the screw nut can have a larger connection area, which not only ensures the sliding of the pad body, but also ensures the stable output of the driving force.

[0031] Specifically, the thickness of the backrest seat 30 is greater than one fifth of the length of the cushion body, which can not only ensure the overall aesthetics of the sofa, but also enable the push-to-play sofa to have a longer support surface, thereby improving the comfort of use.

[0032] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
