Referring to fig. 1-2, a first embodiment of the present utility model provides a seat adjusting device 1, which includes a first connecting member 11, a second connecting member 12 and a third connecting member 13 sequentially disposed, wherein the second connecting member 12 is movably connected to an outer surface of the first connecting member 11, the second connecting member 12 is slidably connected to an outer surface of the third connecting member 13, and the first connecting member 11 is slidably connected to an inside of the third connecting member 13; a spring 14 is arranged in the third connecting piece 13, and two ends of the spring 14 are respectively abutted with the bottom end 131 of the third connecting piece 13 and one end, close to the third connecting piece 13, of the first connecting piece 11; the first link 11 is provided with a projection 111 on its boundary, and when the boundaries of the projection 111 and the third link 13 are relatively fixed in a direction perpendicular to the sliding direction and are abutted together against the boundary of the second link 12, the second link 12 moves on the first link 11 to adjust the compression amount of the spring 14.

It will be appreciated that the outer wall diameter of the first connector 11 is smaller than the inner wall diameter of the third connector 13, the first connector 11 being slidably connected to the inside of the third connector 13, whereby the first connector 11 is slidable inside the second connector 12. The two ends of the second connecting piece 12 are respectively sleeved on the first connecting piece 11 and the second connecting piece, and the sleeved area of the second connecting piece 12 comprises the area of sliding connection between the first connecting piece 11 and the third connecting piece 13. The second connecting member 12 is movably connected to the outer surface of the first connecting member 11, i.e. the second connecting member 12 is movable relative to the first connecting member 11 on the first connecting member 11. The second connecting member 12 is slidably connected to the outer surface of the third connecting member 13, i.e. the second connecting member 12 is slidable on the outer surface of the third connecting member 13.

It may be appreciated that a spring 14 may be disposed inside the third connecting member 13, and two ends of the spring 14 respectively abut against the bottom end 131 of the third connecting member 13 and one end of the first connecting member 11 near the third connecting member 13. And a bump 111 may be provided on the boundary of the first connection member 11. The bump 111 may be exposed on the surface of the third connecting member 13 and abut against the boundary of the second connecting member 12. And the boundary of the protrusion and the third link 13 remains relatively fixed in the direction perpendicular to the sliding direction, i.e., the orientation of the protrusion 111 in the direction perpendicular to the sliding direction is unchanged, and only the distance of the protrusion 111 from the bottom end 131 of the third link 13 is changed when the movement of the second link 12 relative to the first link 11 in the direction away from the bottom end 131 of the third link 13 is controlled.

Specifically, when the boundary of the projection and the third link 13 is kept relatively fixed in the direction perpendicular to the sliding direction and abuts the boundary of the second link 12 together, the spring 14 located inside the third link 13 is in an expanded state, and the compression amount of the spring 14 is minimized. The smaller the compression, the longer the spring 14, the softer the seat and the smaller the amplitude of the seat vibration. When the protrusion and the border of the third connecting piece 13 are abutted against the border of the second connecting piece 12 together, the second connecting piece 12 can be controlled to move relative to the first connecting piece 11 in a direction away from the bottom end 131 of the third connecting piece 13, so as to drive the first connecting piece 11 to slide in the third connecting piece 13 in a direction close to the bottom end 131 of the third connecting piece 13, so that the relative retraction distance between one end of the first connecting piece 11 close to the third connecting piece 13 and the bottom end 131 of the third connecting piece 13 is reduced, and the spring 14 is compressed, so that the compression amount of the spring 14 is increased. The higher the compression of the spring 14, the shorter the spring 14, the stiffer the seat, and the smaller the amplitude of the seat vibration. When only the protrusion 111 is exposed on the surface of the third connecting member 13 and abuts against the boundary of the second connecting member 12, and a certain distance is provided between the protrusion 111 and the boundary of the third connecting member 13, the spring 14 is compressed at this time, and a certain compression amount is provided, at this time, the second connecting member 12 can be controlled to move relative to the first connecting member 11 in a direction away from the bottom end 131 of the third connecting member 13 or in a direction close to the bottom end 131 of the third connecting member 13, so as to drive the first connecting member 11 to slide in the third connecting member 13 correspondingly in a direction close to the bottom end 131 of the third connecting member 13 or slide in a direction away from the bottom end 131 of the third connecting member 13, so as to reduce or increase a relative retraction distance between one end of the first connecting member 11 close to the third connecting member 13 and the bottom end 131 of the third connecting member 13, so as to compress the spring 14 or expand the spring 14, thereby increasing or reducing the compression amount of the spring 14, and further adjusting the seat softness caused by shock absorption. In addition, the compression amount of the spring 14 can be adjusted by controlling the movement of the second connecting piece 12 relative to the first connecting piece 11, so that the operation is simpler.

With reference to fig. 2 and 3, further, a first boundary protrusion 121 is disposed on a boundary of the second connecting member 12 near one end of the third connecting member 13, a second boundary protrusion 132 is disposed on a boundary of the third connecting member 13, and the second boundary protrusion 132 and the bump 111 jointly abut against the first boundary protrusion 121.

In this embodiment, the sliding groove 133 may be parallel to the direction perpendicular to the bottom end 131 of the third connecting member 13, so that when the second connecting member 12 slides on the outer surface of the third connecting member 13 or the second connecting member 12 moves relative to the first connecting member 11, the first connecting member 11 is driven to slide inside the third sliding sleeve, and the protrusion 111 is driven to slide in the sliding groove 133 along the direction perpendicular to the bottom end 131 of the third connecting member 13. In addition, by arranging the chute 133, two ends of the protruding block 111 can be abutted against two ends of the chute 133, so that the relative fixation of the boundary between the protruding block 111 and the third connecting piece 13 in the direction perpendicular to the sliding direction is realized, the protruding block 111 is driven to move in the direction perpendicular to the sliding direction when the second connecting piece 12 moves relative to the first connecting piece 11, and further, the first connecting piece 11 is driven to move integrally when the second connecting piece 12 moves relative to the first connecting piece 11, and the effect that the second connecting piece 12 moves relative to the first connecting piece 11 cannot be achieved.
