[0023] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] The general idea of ​​the utility model is: in view of the problem that the existing bicycle seat is an integrated saddle and cannot adjust the angle to adapt to the sitting posture of the rider, which brings about a poor user experience, the utility model provides a fully adjustable bicycle seat device, which is composed of a seat cushion assembly, a plurality of liftable buffer devices, an adaptive adjustment device, a support device and a rod assembly, wherein the lower end of the support device is fixed to the upper end of the rod assembly, the adaptive adjustment device is installed at the upper end of the support device, the lower ends of the plurality of liftable buffer devices are respectively clamped in the plurality of mounting parts of the adaptive adjustment device, and the upper ends of the plurality of liftable buffer devices are respectively arranged below the seat cushion assembly. When the rider sits on the seat cushion, the seat cushion bears the weight of the human body and transmits it to the adaptive adjustment device through the liftable buffer device at the bottom, and the gravity is transmitted to the rod assembly through the support device by pressing the adaptive adjustment device; therefore, when the vehicle is riding on an uneven road, the bump impact force generated is compressed and absorbed by the elastic force through the liftable buffer device installed at the bottom of the seat cushion, so as to reduce the impact force caused by the bump on the human body and improve the riding comfort.

[0026] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the utility model and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the utility model and the technical features in the embodiments can be combined with each other.

[0027] Figure 1 The figure is a schematic diagram of the structure of an all-round adjustable bicycle seat device provided by an embodiment of the utility model. Figure 1 As shown, the fully adjustable bicycle seat device provided by the utility model comprises a seat cushion assembly 1, a plurality of liftable buffer devices 2, an adaptive adjustment device 3, a support device 4 and a vehicle bar assembly 5. Among them, the lower end of the support device 4 is fixed to the upper end of the vehicle bar assembly 5, the adaptive adjustment device 3 is installed on the upper end of the support device 4, the lower ends of the plurality of liftable buffer devices 2 are respectively clamped in the plurality of mounting parts of the adaptive adjustment device 3, and the upper ends of the plurality of liftable buffer devices 2 are respectively arranged below the seat cushion assembly 1. When the rider sits on the seat cushion, the seat cushion bears the weight of the human body and transmits it to the adaptive adjustment device through the plurality of liftable buffer devices at the bottom. The adaptive adjustment device transmits the gravity to the vehicle bar assembly through the support device by compressing the adjustment spring inside it, thereby realizing the shock-absorbing effect. When riding on an uneven road, a bumpy impact force will be generated, and the spring in the liftable buffer device installed at the bottom of the seat cushion will be compressed to absorb the elastic force, thereby reducing the impact force caused by the bump on the human body and improving the riding comfort. Those skilled in the art can understand that the bar assembly in the present application is a component of the vehicle itself, and the bar assembly may or may not be equipped with a buffer spring according to the vehicle configuration. When the bar assembly is equipped with a buffer spring, the buffer spring inside the bar assembly is compressed to play a buffering role, thereby achieving two-level shock absorption, and when the rider rides on a bumpy road, the external force can be reduced, making the ride more comfortable.

[0028] Further, in an embodiment of the present invention, if Figure 1 As shown, the seat cushion assembly 1 includes a front seat cushion 11, a left seat cushion 12 and a right seat cushion 13, and a liftable buffer device 2 is respectively arranged below the front seat cushion 11, the left seat cushion 12 and the right seat cushion 13. By dividing the seat cushion assembly into three parts according to ergonomics, and arranging a liftable buffer device under each seat cushion, when the rider needs to adapt to different road conditions and the tilt state of the vehicle by constantly changing the riding posture, the seat cushions in different directions can adjust the angles in time according to the rider's sitting posture. For example, when the rider tilts his body to the right, the force borne by the right seat cushion will be greater than that of the front seat cushion and the left seat cushion. The liftable buffer device under the seat cushion is used to adjust the different forces accordingly (the liftable buffer device under the right seat cushion is compressed more when the force on the right side is large). As a result, the seat can adjust the deflection angle of the seat automatically according to the offset of the rider's center of gravity and the force conditions of different seat cushion areas to avoid friction between the inner thigh and the seat when pedaling, which will increase the squeezing and friction on the perineum and make people feel painful.

[0029] Furthermore, in an embodiment of the utility model, a gap is provided between the front seat cushion 11 and the left seat cushion 12 and the right seat cushion 13, and a gap is provided between the left seat cushion 12 and the right seat cushion 13. By providing the gaps between the three seat cushions, in addition to having a strong ventilation and heat dissipation effect, the discomfort caused by the heat generated by the friction between the buttocks and the saddle is avoided; it also relaxes the male testicles and avoids the discomfort caused by the pressure of the seat.

[0030] Furthermore, in an embodiment of the utility model, the height of the front seat cushion 11 is lower than the height of the left seat cushion 12 and the right seat cushion 13, and the height of the left seat cushion 12 and the right seat cushion 13 are equal. When the body leans forward, the perineum will naturally press the front seat cushion forward. By designing the height of the front seat cushion itself to be lower than the height of the rear seat cushion, when the perineum presses the seat cushion, the liftable buffer device under the seat cushion is compressed and the seat cushion sinks, which can effectively reduce the reaction force of the seat cushion on the perineum, reduce the pressure on the perineum, and make the rider feel more comfortable, especially for long-distance riders, it is more comfortable and less prone to fatigue.

[0031] Figure 2 The figure is a schematic structural diagram of a liftable buffer device of an all-around adjustable bicycle seat device provided by an embodiment of the utility model; Figure 3 Shown Figure 2 The exploded view of the liftable buffer device is shown in FIG. Figure 2 and Figure 3 As shown, the liftable buffer device 2 includes a seat cushion connection assembly, a cover 23, a pin 24, a buffer spring 25 and a buffer spring seat 26. The seat cushion connection assembly includes a seat cushion connection plate 21 and a seat cushion connection plate support rod 22 welded together. The buffer spring 25 is placed at the bottom of the buffer spring seat 26. The cover 23 is installed at the upper end of the buffer spring seat 26. The lower end of the seat cushion connection assembly is inserted into the buffer spring seat 26 through the notch 231 of the cover 23 and pressed on the top of the buffer spring 25. The pin 24 is inserted into the pin hole of the seat cushion connection plate support rod 22, and then the cover 23 is locked with the buffer spring seat 26 by a screw nut. Therefore, when the rider rides, gravity is transmitted to the buffer spring through the seat cushion connection plate and the seat cushion connection plate support rod, so that the buffer spring is compressed, and then the height of the seat cushion changes, which plays a buffering role.

[0032] Figure 4 The figure is a schematic structural diagram of an adaptive adjustment device and a support device of an all-round adjustable bicycle seat device provided by an embodiment of the utility model; Figure 5 The figure shows a rear view of a liftable buffer device, a self-adaptive adjustment device and a support device of an all-round adjustable bicycle seat device provided by an embodiment of the utility model; Figure 6 Shown Figure 5 The cross-sectional view of section AA is shown in FIG. Figure 4-6 As shown, the adaptive adjustment device 3 includes a lower mounting base plate 31, an intermediate adjustment spring 32, an upper gasket 33, an upper spring washer 34, an upper mounting base plate 35, a fixing screw 36, an intermediate pre-tightening bolt 37, a lower gasket 38 and a lower spring washer 39, a cotter pin 310, and a locking nut 311. Among them, the intermediate adjustment spring 32 is placed between the upper mounting base plate 35 and the lower mounting base plate 31, the upper mounting base plate and the lower mounting base plate are connected by the intermediate pre-tightening bolt 37, and the upper and lower base plates are locked by the locking nut 311, and then the locking nut 311 is fixed by the cotter pin 310. In addition, the upper spring washer 34 and the upper gasket 33 are arranged on the upper and lower surfaces of the junction of the upper mounting plate and the intermediate pre-tightening bolt, and the lower gasket 38 and the lower spring washer 39 are arranged on the upper and lower surfaces of the junction of the lower mounting base plate and the intermediate pre-tightening bolt, so as to achieve the effect of tight fixing.

[0033] Further, in an embodiment of the present utility model, if Figure 4 As shown, the surface of the lower mounting base plate 31 is provided with a first mounting portion 312, and the surface of the upper mounting base plate 35 is provided with a second mounting portion 351 and a third mounting portion 352, and the first mounting portion, the second mounting portion and the third mounting portion are used to fix the liftable buffer device under each seat cushion.

[0034] Further, in an embodiment of the present utility model, if Figure 3 As shown, a flange 261 is provided at the upper end of the buffer spring seat 26, and the buffer spring seat 26 of the liftable buffer device 2 arranged below the front seat cushion 11 is clamped and connected with the first mounting portion 312 via the flange 261, and the buffer spring seat 26 of the liftable buffer device 2 arranged below the left seat cushion 12 and the buffer spring seat 26 of the liftable buffer device 2 arranged below the right seat cushion 13 are clamped and connected with the second mounting portion 351 and the third mounting portion 352 via the flange 261 respectively. The flange provided on the buffer spring seat can realize the fixed connection between the liftable buffer device and the adaptive adjustment device, so as to avoid the left and right movement of the buffer device during riding.

[0035] Further, in an embodiment of the present utility model, if Figure 6As shown, there is an arcuate contact between the arcuate surface of the upper mounting base plate 35 and the middle adjusting spring 32. When the rider encounters a road section such as uphill, downhill or turning during the riding process, the body will naturally adjust its sitting posture according to the different terrain and topography to maintain the body's balance. When the rider keeps twisting the buttocks and tilting the body forward and backward, the pressures on the seat cushions in the front and back, left and right positions are different and constantly changing. Since there is an arcuate contact between the arcuate surface of the upper mounting base plate and the middle adjusting spring, when the body is tilted or the pressure difference between the left and right sides is large, the spring on the side with greater pressure will be compressed more, and the seat cushion will automatically tilt to the direction with greater force to adapt to the sitting posture of the human body, reducing the pressure caused by the wear of the inner thigh caused by excessive pressure on one side.

[0036] Further, in an embodiment of the present invention, if Figure 4 As shown, the support device 4 includes two identical support rods 41, and the support rod 41 includes two integrally formed vertical parts 411 and a horizontal part 412, and the horizontal part 412 is arranged between the vertical parts 411; the car bar assembly 5 includes a car bar body and two movable jackets 511 arranged at the upper end of the car bar body.
