Therefore, the lifting and tilting adjustable seating furniture provided by the utility model can effectively solve the problem of poor user experience caused by the fact that the existing seating furniture cannot be adjusted in seating height and the seating surface cannot be tilted.

In this embodiment, the lifting mechanism 2 includes a vertical guide rail 201, a lifting platform 202, and a longitudinal motor screw assembly 203. The vertical guide rail 201 is provided with a vertical guide slot 2011. The end of the lifting platform 202 is inserted into the vertical guide slot 2011. The longitudinal motor screw assembly 203 is connected to the lifting platform 202, and drives the lifting platform 202 to slide up and down along the vertical guide slot 2011. When the sitting height of the riding mechanism 1 needs to be adjusted, the longitudinal motor screw rod assembly 203 drives the lifting platform 202 to move up and down.

The inclination angle adjusting mechanism 3 comprises a fixed supporting rod 301, a Y-shaped supporting assembly 302, a first tension spring 303 and a second tension spring 304.

The lower end of the fixed support rod 301 is fixed to the front end of the lifting mechanism 2, and the upper end is in contact with the bottom surface of the front end of the riding mechanism 1. The lower end of the Y-shaped supporting component 302 is fixed at the rear end of the lifting mechanism 2, and the upper end is slidably connected with the bottom surface of the rear end of the riding mechanism 1.

Specifically, referring to fig. 2, the Y-shaped support assembly 302 includes a longitudinal vertical rod 3021, a first diagonal rod 3022, a first slider 3023, a second diagonal rod 3024, and a second slider 3025.

It will be appreciated that the sliding connection member 104 is driven by the transverse motor screw assembly 105 to approach the fixed connection member 103, so that the degree of arching of the spring net 102 is increased, and thus the supporting hardness during riding is improved, whereas the sliding connection member 104 is driven by the transverse motor screw assembly 105 to approach the fixed connection member 103, so that the degree of arching of the spring net 102 is reduced, and thus the supporting hardness during riding is reduced.

Further, referring to fig. 3, the ride platform 101 includes a ride plate 1011, rollers 1012, shock absorbing slide bars 1013, and compression springs 1014. The seat board 1011 is located outside the vertical guide slot 2011, the roller 1012 is located inside the vertical guide slot 2011, one end of the shock absorbing sliding rod 1013 is slidably inserted into the seat board 1011, the other end is connected with the roller 1012, the compression spring 1014 is sleeved on the shock absorbing sliding rod 1013, and is used for driving the shock absorbing sliding rod 1013 to slide towards the vertical guide rail 201 relative to the seat board 1011, so that the roller 1012 pushes against the vertical guide slot 2011 to ensure the stability of the seat board 1011 when sliding up and down. Further, referring to fig. 4, the above-mentioned shock absorbing structures may be disposed in multiple directions of the riding board 1011, or the lifting platform 202 provided by the present utility model also includes similar shock absorbing structures, which are not described in detail in this embodiment.
