[0002] Sofa, this word comes from the transliteration of the English word "sofa", which refers to a cushioned multi-seat chair, usually equipped with a backrest and armrests, and is a type of soft furniture.

[0003] Many existing sofas are designed with shock absorption in mind, aiming to enhance the user's sitting and lying experience. However, while the sofa itself may have good shock absorption properties, most sofa legs are not specifically designed for shock absorption, which can affect the overall comfort and stability of the sofa. Furthermore, sofas are typically large and heavy, which can cause inconvenience in daily use, especially when adjusting the sofa's position to suit the room layout or cleaning needs. Utility Model Content

[0007] As a further improvement of the present invention, the telescopic mechanism includes a cylindrical frame fixedly connected to the lower end of the sofa body, a telescopic column is slidably inserted in the cylindrical frame, the lower end of the telescopic column is fixedly connected to the upper end of the foot pad, one end of the telescopic column located in the cylindrical frame is fixedly connected to a spring, and the other end of the spring is fixedly connected to the lower end of the sofa body.

[0008] As a further improvement of the present invention, the driving mechanism includes a worm gear arranged above the sliding plate, the two ends of the worm gear are respectively rotatably connected to the inner side walls of the mounting frame, a motor is fixedly connected to the outer side wall of the mounting frame, the output shaft end of the motor passes through the mounting frame and is connected to the worm gear, worm wheels are engaged on both sides of the worm gear, and threaded rods are fixedly inserted on the two worm wheels, one end of the two threaded rods are rotatably connected to the lower end of the sofa body, and the other ends of the two threaded rods are threaded through the sliding plate and rotatably connected to the upper end of the fixed plate.

[0009] As a further improvement of the present invention, each of the foot pads has an inverted cone-shaped structure, which is convenient for stably supporting the sofa while effectively increasing the contact area with the ground.

[0010] As a further improvement of the present invention, each of the foot pads is made of rubber, which is elastic and has good wear resistance and anti-slip properties.

[0011] As a further improvement of the present invention, there are four universal wheels, which are respectively located at the four corners of the installation frame.

[0012] Beneficial effects of the utility model:

[0013] By setting a telescopic mechanism between each foot pad and the sofa body, the problem of insufficient shock-absorbing design of the support leg is effectively solved. It not only enhances the overall stability of the sofa, but also significantly improves the user's sitting and lying comfort and shock-absorbing effect during use.

[0014] The driving mechanism within the mounting frame—a combination of a motor, worm, worm gear, and threaded rod—allows the sliding plate and universal wheels to move up and down easily. This allows the sofa to be pushed when needed, reducing the user's burden when adjusting the sofa's position and improving its flexibility and ease of use.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Figure 1-Figure 3 , a sofa with pressure buffering and shock absorption function, comprising a sofa body 1, foot pads 4 are provided at the bottom of the four corners of the sofa body 1, each foot pad 4 is made of rubber material, which is elastic and has good wear resistance and anti-slip performance, can effectively reduce the friction and vibration between the sofa body 1 and the ground, and protect the sofa body 1 from damage; each foot pad 4 is connected to the sofa body 1 through a telescopic mechanism, and the telescopic mechanism is used to enhance the stability and comfort of the sofa; each foot pad 4 is an inverted cone structure, which is convenient for stably supporting the sofa body 1 while also effectively increasing the contact area with the ground; the telescopic mechanism includes a cylindrical frame 2 fixedly connected to the lower end of the sofa body 1, a telescopic column 3 is slidably inserted in the cylindrical frame 2, the lower end of the telescopic column 3 is fixedly connected to the upper end of the foot pad 4, one end of the telescopic column 3 located in the cylindrical frame 2 is fixedly connected to a spring 13, and the other end of the spring 13 is fixedly connected to the lower end of the sofa body 1, and the setting of the spring 13 can absorb and disperse the impact force applied to the sofa, effectively relieve the pressure applied to the sofa, and extend the service life of the sofa.

[0022] The same mounting frame 5 is provided between the four foot pads 4, and the mounting frame 5 is fixedly connected to the lower end of the sofa body 1. A sliding plate 12 is provided inside the mounting frame 5 for sliding up and down. A driving mechanism for driving the sliding plate 12 to move is provided in the mounting frame 5, which can conveniently control the up and down movement of the sliding plate 12, thereby realizing the movement and fixation of the sofa body 1. The driving mechanism includes a worm 7 provided above the sliding plate 12, and the two ends of the worm 7 are respectively rotatably connected to the inner side walls of the mounting frame 5. A motor 6 is fixedly connected to the outer side wall of the mounting frame 5, and the output shaft end of the motor 6 passes through the mounting frame 5 and is connected to the worm 7. The drive of the motor 6 can drive the worm 7 to rotate, thereby realizing power transmission. A worm gear 8 is engaged on both sides of the worm 7, and the meshing transmission of the worm 7 and the worm gear 8 is self-locking and can It can effectively prevent objects from moving on their own when not acted upon by external forces, thereby improving the stability of the device. Threaded rods 9 are fixedly connected to the two worm gears 8, and one end of the two threaded rods 9 is rotatably connected to the lower end of the sofa body 1.
