Wherein, the trigger mechanism comprises an unlocking structure 5, an adjusting handle 3 and a reversing device 4.

Wherein, the tubular member 2 includes an inner tube 21 having a seat mounting end mounted to the bottom of the seat, the seat mounting end having a seat connecting block 24 and a handle connecting block 23, the seat connecting block 24 being mounted and fixed to the seat cushion bracket 11, and the adjustment handle 3 being rotatably connected to the handle connecting block 23. An unlocking structure 5 is arranged in the inner pipe 21, and a locking device 6 is positioned in the inner pipe and fixed at the bottom of the inner pipe.

The unlocking structure 5 moves downward by an external force and opens the switch of the locking device 6. The locking device 6 is of a conventional structure and functions to lock the tubular assembly 2, and more specifically, the locking device 6 prevents the inner tube from moving up and down, which is not described in detail herein.

In the present embodiment, the adjusting handle 3 passes through the through hole 33 of the adjusting handle 3 and the through hole 231 of the handle connecting block 23 through a pivot (not shown in the figure) to realize the movable connection between the adjusting handle 3 and the handle connecting block 23. The number of the handle connecting blocks 23 can be two, and the adjusting handle is hinged between the two handle connecting blocks 23 after the adjusting handle is pivoted through the through hole 33 of the adjusting handle 3 and the through holes 231 of the two handle connecting blocks 23. The first end of the adjustment handle 3 has a grip 31 and the second end 32 is provided with a reversing device 4, which enables the adjustment handle 3 to be moved upwards and downwards when a user acts on the grip. The adjustment handle 3 forms a lever that pivots.

In the present embodiment, the reversing device 4 has a first driving end 41 and a second driving end 42, when the adjustment handle 3 is rotated upwards, the first driving end 41 will drive the unlocking structure 5 to move downwards and open the switch of the locking device 6 due to the lever principle; when the adjustment handle 3 is rotated downwards, the second driving end 42 drives the unlocking structure 5 to move downwards and opens the switch of the locking device 6. That is, when the adjustment handle 3 is rotated upward or downward, the reversing device 4 will drive the unlocking structure 5 to move downward and open the switch of the locking device 6 under the action of the adjustment handle 3.

In another embodiment, the first driving end 41 is fixedly connected to the second end 32 of the adjustment handle 3, the second driving end 42 is movably connected to the first driving end 41, and the second driving end 42 of the reversing device can also be movably connected to the seat mounting end.

The tubular assembly 2 further includes an outer tube 22, and the bottom of the inner tube 21 and a portion of the inner tube section adjacent to the bottom are sleeved in the outer tube 22 and can move up and down. The bottom of the outer tube 22 is provided with a fastening shaft 8, the locking device 6 is arranged on the fastening shaft 8, when the switch of the locking device 6 is turned on, the locking device 6 moves up and down along the fastening shaft 8, and when the switch of the locking device 6 is turned off, the locking device 6 is fixed on the fastening shaft and cannot move up and down along the fastening shaft 8. The outer tube 22 is further internally provided with an elastic member 7, the fastening shaft 8 is sleeved with the elastic member 7, one end of the elastic member 7 is installed at the bottom of the outer tube 22, and the other end of the elastic member is connected with the locking device 6. The elastic member 7 may be a spring.

Referring to fig. 3, when seat 1 is in a balanced state, i.e., seat 1 is at a universal height, in which the spring is in a free state, the switch of locking device 6 is turned off and fixed to the fastening shaft. In this state, the height of the seat 1 can be adapted to most people, and the number of times of height adjustment by the user can be reduced.

Referring to fig. 4, when it is desired to raise the saddle 1, the user turns (pulls) the adjustment handle 3 upwards, the reversing device 4 pushes the unlocking structure 5 under the action of the adjustment handle 3, the unlocking structure 5 thus moves downwards to open the switch of the locking device 6, and the saddle 1 follows the adjustment handle 3 and rises. During the raising of the vehicle seat 1, the locking device will move upwards along the fastening shaft 8 and the inner tube 21 will move upwards along the outer tube 22. When the saddle 1 is adjusted to a proper height, the adjusting handle 3 is loosened, the unlocking structure 5 does not act on the locking device 6 any more, the switch of the locking device 6 is closed and cannot move along the fastening shaft, the saddle heightening operation is completed, and the spring is in a compressed state at the moment. In this process, the direction of movement of the adjustment handle 3 coincides with the direction of movement of the saddle, both upwards. From the above, it can be seen that the height adjustment of the saddle 1 can be achieved in only one step, i.e. by pulling the adjustment handle 3 upwards.

Referring to fig. 5, when it is desired to lower the saddle 1, the user turns (presses) the adjustment handle 3 downwards, the reversing device 4 pushes the unlocking structure 5 under the action of the adjustment handle 3, the unlocking structure 5 thus moves downwards to open the switch of the locking device, and the saddle 1 follows the adjustment handle 3 and descends. During the lowering of the seat 1, the locking device 6 will move down along the fastening shaft 8 and the inner tube 21 will move down along the outer tube 22. When the saddle 1 is adjusted to a proper height, the adjusting handle 3 is loosened, the unlocking structure 5 does not act on the locking device 6 any more, the switch of the locking device 6 is closed and cannot move along the fastening shaft, the saddle lowering operation is completed, and the spring is in a compressed state at the moment. The introduction of the spring will have a linearly increasing damping effect when the height is adjusted downwards. In this process, the direction of movement of the adjustment handle 3 coincides with the direction of movement of the saddle, both downwards. From the above, it can be seen that lowering the saddle 1 can be achieved in only one step, i.e. by pressing down the adjustment handle 3.

Therefore, when the height of the saddle is adjusted, the movement direction of the adjusting handle, the movement direction of the saddle and the stretching direction of the elastic piece are consistent, and the height of the saddle can be adjusted more conveniently by a user.

The utility model discloses a saddle height adjusting device can the exclusive use. The saddle assembly can also be used together with a saddle to form a saddle assembly, as shown in fig. 3, the saddle 1 comprises a cushion 12 and a cushion bracket 11, the saddle height adjusting device is installed and fixed at the bottom of the saddle, the tail part of the saddle 1 is provided with a notch 9, a handheld part 31 is arranged in the notch 9, the handheld part 31 is embedded in the notch 9 to form a whole with the saddle 1, the appearance is attractive, and the height of the saddle is convenient to adjust.

When the saddle height adjusting device and the saddle assembly are applied to a bicycle or an electric moped, a user can adjust the height of the saddle through one step and one-hand operation in the process of using the bicycle or the electric moped, and the adjusting handle directly acts on the saddle when the height of the saddle is adjusted, the movement direction of the adjusting handle is consistent with the movement direction of the saddle, and smoother user experience can be obtained.
