[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Example 1:

[0033] In this embodiment, as Figures 1-9 As shown, the present invention proposes a telescopic electric sofa, including a sofa frame 1, armrests 101 on both sides of the sofa frame, a backrest 102 at the rear end of the sofa frame, a cushion 2 installed on the backrest, the bottom of the cushion being fixed to the backrest, the top of the cushion being hinged to the backrest, a sofa seat 3 at the front end of the sofa frame, an electric telescopic rod 4 between the sofa frame and the sofa seat, the fixed end of the electric telescopic rod being connected to the bottom of the sofa frame, the output end of the electric telescopic rod being connected to the inner end of a connecting block 5, the outer end of the connecting block being connected to the inner side of the sofa seat, the extension and retraction of the sofa seat being controlled by the electric extension and retraction of the electric telescopic rod, and directional wheel assemblies 6 symmetrically provided at the bottom of the sofa seat to assist the extension and retraction of the sofa seat.

[0034] In this example, the directional wheel assembly includes a wheel seat and directional wheels. The wheel seat is installed at the bottom of the sofa seat, and the directional wheels are installed on the wheel seat. Each sofa set has a pair of directional wheel assemblies symmetrically arranged. The electric telescopic rod has at least two sets to enhance stability. The electric telescopic rod can also be a multi-stage or even multiple electric telescopic rod.

[0035] In this embodiment, the sofa frame is further configured with a support rail 7 at the bottom and several pulleys 8 between the support rail and the bottom of the sofa seat. The pulleys assist the sofa seat in extending and retracting. The support rail and pulleys can support and smoothly move the sofa seat. Multiple sets of support rails and pulleys are provided and do not obstruct the extension and retraction of the electric telescopic rod.

[0036] In this embodiment, the support rail is further provided with a diagonal brace 9 below the support rail. The upper end of the diagonal brace is connected to the support rail, and the lower end of the diagonal brace is connected to the fixed frame. The diagonal brace reinforces and supports the support rail.

[0037] In this embodiment, the sofa seats are further configured to be in three sets, all of which have the same size and specifications, and each set of sofa seats is connected to an electric telescopic rod.

[0038] In this embodiment, the electric telescopic rod is further configured to be remotely controlled by a remote control. This technology is existing technology. The remote control can control the three sets of sofa seats to extend individually through different buttons, or it can control the three sets of sofa seats to extend simultaneously with one button. It can meet the needs of users in both sitting and lying down states, especially in situations where multiple people use the equipment and have different needs, making it highly functional.

[0039] In another example, control buttons are symmetrically arranged on the inside of the armrest. There is a pair of control buttons, which control the extension and retraction of the sofa seat in the corresponding direction. When the control buttons control the extension and retraction of the sofa seat, the middle sofa seat is usually in a fixed mode and cannot be extended or retracted, while the sofa seats on both sides can be extended and retracted under the drive.

[0040] Example 2:

[0041] In this embodiment, as Figures 1-10 As shown, the present invention proposes a telescopic electric sofa, including a sofa frame 1, armrests 101 on both sides of the sofa frame, a backrest 102 at the rear end of the sofa frame, a cushion 2 installed on the backrest, the bottom of the cushion being fixed to the backrest, the top of the cushion being hinged to the backrest, a sofa seat 3 at the front end of the sofa frame, an electric telescopic rod 4 between the sofa frame and the sofa seat, the fixed end of the electric telescopic rod being connected to the bottom of the sofa frame, the output end of the electric telescopic rod being connected to the inner end of a connecting block 5, the outer end of the connecting block being connected to the inner side of the sofa seat, the extension and retraction of the sofa seat being controlled by the electric extension and retraction of the electric telescopic rod, and directional wheel assemblies 6 symmetrically provided at the bottom of the sofa seat to assist the extension and retraction of the sofa seat.
