A liftable sofa support frame is a device that provides height adjustment and support for the sofa, which can adjust the height and angle of the sofa according to the user's needs, so as to provide a comfortable sitting posture experience that better meets the individual needs of users. This support frame is usually installed at the bottom of the sofa and realizes the lifting and angle adjustment functions through mechanical or electric devices, meeting the needs of modern consumers for personalized and comfortable furniture.

[0003] However, there are some defects in the existing liftable sofa support frames during use. First of all, many lifting adjustment devices require users to manually make complex adjustments during operation. The adjustment process is cumbersome and lacks flexibility, making it difficult to achieve precise height and angle adjustment, which affects the user experience. Secondly, the existing lift support frame designs often ignore the user's need for angle adjustment during the adjustment process. The sofa can only perform limited height adjustment and cannot meet the user's need for adjusting the tilt angle in different sitting postures. In addition, some designs lack sufficient stability, and the sofa is prone to shaking during the adjustment process, affecting the use safety. Therefore, a new type of liftable sofa support frame is needed to improve the above devices. Summary of the Utility Model

In this way, the staff can flexibly adjust the height of the sofa according to the needs of the user to ensure the best comfort.

[0033] To further enhance the user experience, especially when the angle of the sofa needs to be adjusted, a slope mechanism 3 is provided on the top plate 25 of the adjustment mechanism 2 on one side. The user can control the start and stop of the power motor 33 to start the motor to push the push rod 32. When the push rod 32 moves forward, the push plate 34 will move forward synchronously. During the forward movement of the push plate 34, it will push the adjustment slope frame 35 to tilt at a certain angle. At this time, the adjustment slope frame 35 is connected to the sofa through the connecting frame 37, so that when the adjustment slope frame 35 tilts, the sofa will also tilt accordingly.

[0034] Through this slope adjustment function, the sofa can provide a more comfortable sitting position for the user. Whether it is necessary to fine-tune the angle or tilt according to the needs of different scenarios, the user can flexibly adjust the height and angle of the sofa to achieve the best sitting experience. This design fully considers the actual needs of the user, not only improving the practicality of the product, but also greatly enhancing its comfort.
