Description

home electric sofa

technical field

The utility model belongs to the technical field of household sofas, in particular to a household electric sofa.

Background technique

With the development of society, people's pursuit of quality of life is constantly improving. For the choice of furniture, consumers are not limited to a single function, but more hope to maximize the utilization rate of furniture, which is modern thinking. For example, seats or sofas, consumers are more in pursuit of comfort, such as functions that can provide multiple usage modes such as reading and lying flat. With the continuous deepening of research and development, some functional sofas have also appeared on the market. However, these sofas still have deficiencies in the aspect of multi-mode use, for example, when they are placed against a wall, they cannot be conveniently switched and adjusted between modes.

Utility model content

In view of this, the utility model provides a household electric sofa, which can not only realize zero placement against the wall, but also provide multiple usage modes such as reading and lying down.

In order to achieve the above object, the technical scheme of the utility model is as follows:

An electric sofa for home use, including a base, the key point of which is that a cushion frame is slidably arranged on the base, a folding leg rest is installed at the front end of the cushion frame, and a chair back is rotatably installed at the rear end. There is a driving mechanism on the top. After the driving mechanism is started, it can drive the cushion frame to slide forward on the base after the foldable leg rest is unfolded; there is a linkage component between the chair back and the cushion frame. When sliding forward, the chair back is able to tilt back relative to the cushion frame.

With the above-mentioned structure, the sofa can be transformed into multiple modes for use, one is: sitting mode, that is, the driving mechanism does not work, and the sofa remains in its original state; the other is: reading mode, that is, the driving mechanism only drives the folding leg rest to unfold, The positions of the cushion frame and the seat back are not adjusted; the third is: flat lying mode, that is, the driving mechanism first drives the folded leg rest to fully unfold, and then drives the seat frame to slide forward. At the same time, driven by the linkage components, The back of the chair is also fully lowered, so that the sofa forms a flat state. And during the switching process of various modes, the upper edge of the chair back can always be located in the same vertical plane, which can ensure that the sofa is never placed or installed against the wall.

As a preference: the cushion frame includes side support plates symmetrically arranged on both sides of the upper end of the base, and the side support plates are slidably installed on the base through slide rails. Adopting the above-mentioned structure facilitates installation and manufacture.

As a preference: the foldable leg rest includes a support frame, and the support frame is rotatably connected to the cushion frame through the flip assembly on both sides. The flip assembly includes a first connecting rod and a second connecting rod whose ends are hinged on the support frame. A connecting rod, and a third connecting rod and a fourth connecting rod whose ends are hinged on the side support plate, wherein the first connecting rod and the third connecting rod are hinged to each other in the middle, and the first connecting rod is connected to the The far end of the fourth connecting rod is hinged, and the second connecting rod is hinged with the far end of the third connecting rod at an end away from the support frame. With the above structure, the electric telescopic rod pushes the fourth connecting rod to move, so that the opening and closing of the foldable leg rest can be realized.

As a preference: the drive mechanism includes an electric telescopic rod and a horizontal rod whose two ends are fixed on the fourth connecting rod, one end of the electric telescopic rod is hinged on the base, and the other end is hinged on the middle of the horizontal rod . The above-mentioned structure is convenient for installation, and can effectively ensure the opening and closing of the foldable leg rest driven by the electric telescopic rod.

As a preference, both ends of the horizontal rod pass through the outside of the fourth connecting rod, and the front end of the side support plate is provided with a limiting part at a position where the horizontal rod passes through. With the above-mentioned structure, after the foldable leg rest is fully opened, the end of the horizontal rod just abuts against the limit portion, thereby driving the side support plate to slide forward, that is, driving the seat cushion frame to slide forward.

As a preference: the linkage assembly includes sequentially hinged fifth connecting rod, sixth connecting rod and seventh connecting rod, wherein the fifth connecting rod is hinged on the chair back at an end away from the sixth connecting rod, and the sixth connecting rod The middle part is rotatably connected with the side support plate through an adapter block, and the seventh connecting rod is hinged on the base at the end away from the sixth connecting rod. With the above structure, it can be ensured that when the cushion frame slides forward, the chair back can tilt and rotate backward relative to the cushion frame.

Preferably, a support beam is provided between the two side support plates, and a return tension spring is provided between the support beam and the sixth connecting rod. With the above structure, when the sofa is retracted from the flat lying mode, the cushion frame and the chair back can be automatically reset by the reset tension spring.

As a preference: the transition block has a first installation part and a second installation part perpendicular to each other, the first installation part is fixedly connected to the side support plate, and the middle part of the sixth connecting rod is hinged on the second installation part . Adopting the above-mentioned structure facilitates installation and avoids movement interference.

As a preference: the seat back is fixedly installed with an adapter plate at the position corresponding to the fifth link, and the two sides of the adapter plate are provided with a first installation plate and a second installation plate extending in opposite directions, wherein the first installation plate It is rotatably connected with the fifth connecting rod, and the second mounting plate is rotatably connected with the side support plate. Adopting the above-mentioned structure facilitates installation and avoids motion interference.

Compared with the prior art, the beneficial effects of the utility model are:

With the household electric sofa provided by the utility model, the sofa can be transformed into multiple modes for use, one is: sitting mode, that is, the driving mechanism does not work, and the sofa maintains the original state; the other is: reading mode, that is, the driving mechanism only drives the turning The folding leg rest is unfolded, and the positions of the cushion frame and the seat back are not adjusted; the third is: flat lying mode, that is, the driving mechanism first drives the foldable leg rest to fully unfold, and then drives the seat cushion frame to slide forward. Driven by the linkage components, the back of the chair is also completely lowered, so that the sofa forms a flat state. And during the switching process of various modes, the upper edge of the chair back can always be located in the same vertical plane, which can ensure that the sofa is never placed or installed against the wall.
