The main support 20 has an upper end 22 and a lower end 23 exposed to the tube 11, and the upper end 22 and the lower end 23 are provided with through holes.
The base 30 is used for pivotally connecting a seat cushion (not shown) of a bicycle, the base 30 includes a seat bow clamping portion 31 and a pivot portion 32, the seat bow clamping portion 31 is located above the pivot portion 32 and is used for clamping a set of seat bows of a seat cushion, the pivot portion 32 of the base 30 has an upper pivot end 321 and a lower pivot end 322, and the upper pivot end 321 and the lower pivot end 322 are both provided with through holes.
The first connecting rod 40 is located at one side of the seat tube 10 and pivoted between the main support 20 and the base 30; the second link 50 is opposite to the first link 40 and located at the other side of the seat tube 10, and is pivotally connected between the main support 20 and the base 30; wherein the upper end of the first link 40 is pivotally connected to the upper pivot 321, the upper end of the second link 50 is pivotally connected to the lower pivot 322, the lower end of the first link 40 is pivotally connected to the upper end 22 of the main support 20, and the lower end of the second link 50 is pivotally connected to the lower end 23 of the main support 20; the first and second connecting rods (40, 50) respectively pass through the through holes via the shaft member 71 to connect the main support 20 and the base 30, and bearings (not shown) are respectively disposed on two sides of the shaft member 71 passing through the main support 20 and on two sides of the shaft member 71 passing through the base 30, so that the first and second connecting rods (40, 50) can movably rotate relative to the main support 20 and the base 30 about the shaft member 71.
The buffer assembly 60 is disposed in the through hole 21, the upper end of the buffer assembly 60 protrudes from the through hole 21 and is located between the first link 40 and the second link 50, and the buffer assembly 60 is connected to the base 30, so as to provide a buffer force to the base 30 to achieve the shock absorbing effect.
In the first embodiment, as shown in fig. 1, 2 and 3, the buffer assembly 60 includes a core 61, a compression spring 62 and a lower blocking member 63, the core 61 is vertically and vertically movably disposed at the through hole 21, the upper end of the core 61 protrudes from the through hole 21 and is located between the first link 40 and the second link 50, the lower blocking member 63 is fixedly disposed in the tube 11, the compression spring 62 is disposed between the core 61 and the lower blocking member 62, the upper end of the core 61 and the base 30 are connected by a pressing member 81, in the first embodiment, one end of the pressing member 81 is pivotally connected to the base 30, the other end of the pressing member 81 is pivotally connected to the upper end of the core 61 by a shaft, and a front end 323 is further disposed between the upper pivot 321 and the lower pivot 322 of the base 30 for pivotally connecting with one end of the pressing member 81.
Thus, when the rider runs through a bumpy road, the bicycle vibrates up and down, and the weight of the rider can push down the buffer assembly 60 through the seat cushion and the base 30 and the pressing member 81, so that the core rod 61 is displaced downwards and the compression spring 62 is pushed down, and the vibration is counteracted and slowed down by the elasticity of the compression spring 62, so that the shock absorbing effect is achieved. Because the seat tube 10 is connected with the base 30 by the first and second connecting rods 40 and 50, and the first and second connecting rods (40 and 50) can only rotate upwards or downwards, the base 30 can rotate upwards or downwards relative to the seat tube 10 no matter the gravity is downwards or the component force is in the front-back direction, and the pressing piece 81 presses the upper end of the buffer assembly 60, so that the core bar 61 can be ensured to be limited to vertically move upwards and downwards in the axial direction of the through hole 21, and the resistance generated by friction between the seat tube 10 and the buffer assembly 60 can be avoided, and the buffer shock absorption is smoother; in addition, since the buffer assembly 60 is limited to move axially, and the core rod 61 is abutted against the compression spring 62 axially, any motion of the core rod 61 can be effectively avoided when the buffer shock is not needed, and the first and second links (40, 50) together with the base 30 and the seat cushion are not easy to shake.
In the second embodiment shown in fig. 4, the upper end of the buffering component 60 and the base 30 are connected by a pressing component 81, one end of the pressing component 81 is pivoted to the base 30, the other end of the pressing component 81 is pivoted to the upper end of the core rod 61 in the buffering component, and in the second embodiment shown in the figure, the other end of the pressing component 81 is pivoted to the upper end of the core rod 61 through a universal joint 82.
In addition, in the above embodiments, the buffer assembly may be used instead of a compression spring, and the cylinder may be a pneumatic cylinder or an oil cylinder, and the cylinder includes a cylinder body and a telescopic rod, where the telescopic rod is movably disposed in the cylinder body, the lower end of the cylinder body is fixedly connected to the tube body through the lower stop member, and the end (i.e. the upper end) of the telescopic rod is directly connected to the core rod and then connected to the base through the pressing member, so that the cylinder can also effectively provide the buffer force to the base, thereby achieving a good shock absorbing effect.
