[0039] 2. When the user leans forward to a comfortable posture, the rider no longer actively presses the front part of the seat body, the saddle automatically stops pivoting, avoiding the angle of the front part of the saddle being too large, causing the comfortable forward leaning posture of the user to be exceeded, and improving the use experience. In this way, the operation reaction time of the spring assembly returning to the first elastic coefficient from the second elastic coefficient is not dependent on the user, and the angle of the front part of the saddle being too large due to the hysteresis of the user's operation is excluded.
[0040] 3. The overall elastic coefficient of the spring assembly is changed by adjusting the elastic coefficient of the magnetorheological spring. The elastic coefficient of the magnetorheological spring can change with the strength of the applied magnetic field, with fast response speed, large adjustment range, and extremely low power consumption. At the same time, the compression deformation of the magnetorheological spring is small. By using the magnetorheological spring and the helical spring in series, the overall compression deformation of the spring assembly can be guaranteed.
[0041] 4. This invention integrates the adaptive adjustment function of the saddle angle according to the user's forward lean into the connecting element, without changing the structure of any other parts in the saddle; and the connecting element is modularly designed with rectangular bodies, cylinders, ball bearings, magnetorheological springs and spring seats, which facilitates assembly and disassembly, and makes it convenient for the maintenance and replacement of its internal parts. The combination of this connecting element with bicycle saddle is suitable for widespread application.
[0042] 5. By cooperating with the support plate and the plug, the relative displacement between the seat body and the saddle frame is limited as much as possible, providing full protection for the mounting ring, a high-load and vulnerable component, and improving the firmness of the connection between the seat body and the saddle frame.

DETAILED DESCRIPTION
[0064] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is described and explained below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application. Based on the examples provided in the present application, all other examples obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
[0065] As Figures 1-19 shown, the present embodiment provides an ergonomic bicycle saddle, which comprises a frame assembly 100 and a saddle 200 mounted on the frame assembly 100. The frame assembly 100 is integrally formed and has a saddle mounting portion 110, which is a hollow tubular structure and is arranged substantially vertically or slightly inclined. A saddle support tube 120 is slidably mounted in the saddle mounting portion 110, and the saddle 200 is attached to the top end of the saddle support tube 120, so as to adjust the extension amount of the saddle support tube 120 according to the height of the user, thereby changing the height of the saddle 200.
[0066] The saddle mounting portion 110 and the saddle support pipe 120 are combined at a position provided with a lock structure 300. When adjusting the height of the saddle 200, the user opens the lock structure 300, adjusts the height of the saddle 200, and then locks the lock structure 300.
[0067] In the embodiment, the saddle 200 includes a saddle framework 210 mounted on the upper end of the saddle support pipe 120 and a seat body 220 mounted on the saddle framework 210. Specifically, the upper end of the saddle support pipe 120 is fixedly provided with a C-shaped ring 230, and the C-shaped ring 230 includes a body 231 and two tabs 232 extending rearward from the body 231. The tabs 232 are provided with square holes 233, and the square holes 233 are fixedly provided with a combination element 400, which includes a rectangular body 410.
[0068] The upper end of the saddle support pipe 120 is in the shape of a truncated cone and passes through the space enclosed by the body 231 and the rectangular body 410 from bottom to top. The body 231 and the rectangular body 410 clamp the saddle support pipe 120, so that the C-shaped ring 230, the saddle support pipe 120, and the combination element 400 are fixedly arranged.
[0069] In other words, the combination element 400 is fixed relative to the saddle support pipe 120. In the embodiment, the saddle framework 210 is mounted on the combination element 400, and the seat body 220 is mounted on the saddle framework 210, thereby forming the overall assembly of the saddle 200.
[0070] Specifically, the two ends of the rectangular body 410 are provided with cylindrical bodies 420, and the cylindrical bodies 420 are sequentially provided with a framework mounting unit 240 and a locking nut 250. The framework mounting unit 240 has a framework mounting long hole 241 and a through hole 242.
[0071] The saddle framework 210 is bent from a metal pipe and is in the shape of an isosceles triangle, including an installation unit combination portion 211 located in the middle of the equal sides. The installation unit combination portion 211 passes through the framework mounting long hole 241. Obviously, the extension direction of the installation unit combination portion 211 is substantially the same as that of the framework mounting long hole 241, that is, the installation unit combination portion 211 and the framework mounting unit 240 are both arranged non-perpendicularly to the cylindrical body 420.
[0072] The end of the cylinder 420 is provided with an external thread matched with the lock nut 250. When installed, the lock nut 250 is tightened to press the skeleton mounting unit 240, so that the angle between the cylinder 420, the saddle skeleton 210 and the skeleton mounting unit 240 tends to change, and then the cylinder 420 is in interference fit with the through hole 242, and the skeleton mounting hole 241 is in interference fit with the mounting unit combination part 211, so that the cylinder 420, the saddle skeleton 210 and the skeleton mounting unit 240 are fixedly arranged.
[0073] It can be understood that the traditional bicycle saddle, the saddle 200 is horizontal or slightly inclined forward, but its levelness is fixed, and the user keeps the body inclined forward at a certain moment during riding, especially when pedaling hard, which causes the saddle 200 to enhance the compression of the local body and produce discomfort.
[0074] In order to eliminate the above problems, the ergonomic bicycle saddle of the embodiment, the front part of the saddle skeleton 210 can be pivoted downward, and the angle of the saddle 200 is adaptively adjusted with the forward inclination of the user's body during riding, avoiding the compression of the local body by the saddle 200, conforming to ergonomics and improving user experience.
[0075] In other words, in the embodiment, the cylinder 420 can rotate relative to the rectangular body 410. Therefore, the rectangular body 410 is fixedly arranged relative to the saddle support pipe 120, the cylinder 420 is fixedly arranged relative to the saddle skeleton 210, and the rotation of the cylinder 420 relative to the rectangular body 410 causes the front part of the saddle skeleton 210 to pivot downward.
[0076] Specifically, the rectangular body 410 is provided with a circular through hole 411 along its axial direction, and the inner diameter of the circular through hole 411 matches the outer diameter of the cylinder 420, so that the cylinder 420 can have a rotational freedom degree relative to the rectangular body 410; the side wall of the cylinder 420 is provided with a guide hole 421, the guide hole 421 is provided with a movable ball 430, and the inner wall of the circular through hole 411 is provided with a groove group 412 arranged in the circumferential direction, and the position of the groove group 412 matches the ball 430; the groove group 412 is formed by a plurality of grooves 413 arranged in the circumferential direction, and the shape and size of the groove 413 match the ball 430.
[0077] Among them, when the ball 430 is in the first elastic state, the cylinder 420 is relatively fixed with the rectangular body 410; when the ball 430 is in the second elastic state, the cylinder 420 rotates relative to the rectangular body 410; and the first elastic state is greater than the second elastic state.
[0078] Thus, in normal riding state, the ball 430 is in the first elastic state, the cylinder 420 is fixed relative to the rectangular body 410, i.e. the front part of the saddle 200 cannot be pivoted downward. When the user needs to lean forward, the ball 430 is in the second elastic state, the cylinder 420 can rotate relative to the rectangular body 410, i.e. the front part of the saddle 200 can be pivoted downward. Thus, when riding, the user leans forward to give the front part of the saddle 200 downward pressure, the angle of the saddle 200 is self-adaptively adjusted with the user's body leaning forward, avoiding the saddle 200 pressing the human body locally, conforming to ergonomics, and improving user experience.
[0079] In other words, the first elastic state is the original state of the ball 430, because generally speaking, the rider is in a non-forward leaning posture most of the time. When the user needs to lean forward, the ball 430 is triggered by the user's operation to convert from the first elastic state to the second elastic state to adapt to the body leaning forward posture.
[0080] In this embodiment, the guide hole 421 has multiple and is arranged in an axial array, and correspondingly, the number of the ball 430 and the pit group 412 is the same as that of the guide hole 421, and is also arranged in an axial array. Thus, on the one hand, the stability of the cylinder 420 rotating relative to the rectangular body 410 is improved, and on the other hand, the firmness of the cylinder 420 being fixed relative to the rectangular body 410 is improved.
[0081] In this embodiment, the spring assembly 440 is arranged in the cylinder 420, and one end of the spring assembly 440 is connected to the cylinder 420, and the other end is connected to the ball 430, so that the ball 430 has an elastic state. Among them, the spring assembly 440 is an adjustable spring, so that the ball 430 has a first elastic state and a second elastic state. And it can be understood that the first elastic state and the second elastic state are also adjustable. In other words, the spring assembly 440 is a positive spring, and the spring coefficient, especially the second spring coefficient, can be adjusted.
[0082] In other words, when the spring assembly 440 is in the first spring coefficient, the ball 430 is in the first elastic state, and when the spring assembly 440 is in the second spring coefficient, the ball 430 is in the second elastic state. Obviously, the first spring coefficient is greater than the second spring coefficient.
[0083] It can be understood that when the user leans forward, the spring assembly 440 is in the second elastic coefficient, the cylinder 420 can rotate relative to the rectangular body 410, the user leans forward to give the front of the saddle 200 downward pressure, the angle of the saddle 200 changes with the user's forward leaning. During the process of the user leaning forward to press the front of the saddle 200, when the user is in a comfortable forward leaning posture, the spring assembly 440 can be triggered to return to the first elastic coefficient, thereby maintaining the current pivot angle of the saddle 200, matching the user's forward leaning posture.
[0084] However, occasionally, the user's triggering of the spring assembly 440 from the second elastic coefficient to the first elastic coefficient can be delayed, which can cause the angle of the saddle 200 to rotate beyond the user's forward leaning, causing discomfort during cycling.
[0085] Therefore, in the bicycle saddle of the present embodiment, when the ball 430 is in the second elastic state, the spring assembly 440 is in the second elastic coefficient configuration: when the spring assembly 440 is in the first pressure state, the cylinder 420 can rotate relative to the rectangular body 410; when the spring assembly 440 is in the second pressure state, the cylinder 420 cannot rotate relative to the rectangular body 410.
[0086] In this way, during the user's forward leaning, when the user has not yet leaned to a comfortable posture, the user actively presses the front of the seat body 220, the front of the seat body 220 receives a relatively large pressure, which can overcome the elastic force of the spring assembly 440 in the second elastic coefficient state, the ball 430 is separated from the pit 413 and enters the adjacent next pit 413 in the pit group 412, so that the cylinder 420 can rotate relative to the rectangular body 410. When the user leans to a comfortable posture, the user no longer actively presses the front of the seat body 220, the front of the seat body 220 receives a pressure that is instantaneously greatly reduced, which cannot overcome the elastic force of the spring assembly 440 in the second elastic coefficient state, the ball 430 cannot be separated from the pit 413, so that the cylinder 420 cannot rotate relative to the rectangular body 410.
[0087] With this arrangement, when the user leans to a comfortable posture, the user no longer actively presses the front of the seat body 220, the saddle 200 automatically stops pivoting, avoiding the front of the saddle 200 rotating downward to an angle that is too large, causing the user to exceed the comfortable forward leaning posture that the user wants to achieve, improving the user experience. In this way, the user's reaction time for triggering the spring assembly 440 from the second elastic coefficient to the first elastic coefficient is not relied on, and the angle of the front of the saddle 200 rotating downward that is too large due to the user's delayed operation is eliminated.
[0088] In this embodiment, the spring assembly 440 is configured as a composite spring, which is formed by connecting the magneto-rheological spring 441 and the coil spring 442 in series. In this way, the elastic coefficient of the spring assembly 440 can be adjusted.
[0089] Specifically, the magneto-rheological spring 441 is fixedly installed in the interior of the cylinder 420, the guide hole 421 extends from the surface of the cylinder 420 to the magneto-rheological spring 441, the coil spring 442 is arranged in the guide hole 421, and the upper end of the coil spring 442 contacts the elastic ball 430, and the lower end of the coil spring 442 contacts the magneto-rheological spring 441.
[0090] In this way, the overall elastic coefficient of the spring assembly 440 is changed by adjusting the elastic coefficient of the magneto-rheological spring 441. The elastic coefficient of the magneto-rheological spring 441 can be changed with the strength of the applied magnetic field, has fast response speed, large adjustment range, and consumes very little power. At the same time, the compression deformation amount of the magneto-rheological spring 441 is small, and the magneto-rheological spring 441 and the coil spring 442 are connected in series, which can guarantee the overall compression deformation amount of the spring assembly 440.
[0091] In this embodiment, the magneto-rheological spring 441 includes a shell 443 fixedly installed in the interior of the cylinder 420, and the shell 443 is provided with a coil 444 and an elastic body unit 445, etc. The shell 443 is arranged to facilitate the assembly of the magneto-rheological spring 441 into the cylinder 420, and the structure in the shell 443 can be achieved by using existing technologies.
[0092] In this embodiment, the side wall of the cylinder 420 is further provided with a mounting groove 422, which is located on the side opposite to the guide hole 421, and the guide hole 421 extends from the surface of the cylinder 420 to the mounting groove 422, so that the guide hole 421 and the mounting groove 422 are in communication; the spring seat 450 is detachably installed in the mounting groove 422, and the magneto-rheological spring 441 is detachably installed in the spring seat 450.
[0093] Specifically, the spring seat 450 includes a seat body 451 and a first flange 452 arranged on the upper end surface of the seat body 451, and the area of the first flange 452 is the same as that of the mounting groove 422; the first flange 452 is provided with a first connecting hole 453, and correspondingly, the bottom surface of the mounting groove 422 is provided with a first threaded hole 423, and the first fastener 401 penetrates the first connecting hole 453 and the first threaded hole 423 in sequence, so that the spring seat 450 is detachably installed in the mounting groove 422.
[0094] The upper end surface of the spring seat 450 is further provided with a stepped slot 454, which includes a large-size slot 455 at the upper side and a small-size slot 456 at the lower side, and the upper end surface of the shell 443 is provided with a second flange 446. The size of the second flange 446 matches the size of the large-size slot 455, and the size of the shell 443 body matches the size of the small-size slot 456, so that the magnetorheological spring 441 is installed in the spring seat 450, and the upper end surface of the magnetorheological spring 441 is flush with the upper end surface of the spring seat 450, so that the magnetorheological spring 441 and the spring seat 450 form a whole which is convenient to install in the installation slot 422.
[0095] The bottom surface of the large-size slot 455 is provided with a second threaded hole 457, and the second flange 446 is provided with a second connecting hole 447, and the second fastener 402 passes through the second connecting hole 447 and the second threaded hole 457 in sequence, so that the magnetorheological spring 441 is detachably installed in the spring seat 450. The second connecting hole 447 is a stepped hole, so that the second fastener 402 can be installed invisibly, without damaging the flatness of the upper end surface of the magnetorheological spring 441 and the spring seat 450.
[0096] Therefore, when assembling the combination element 400 of the embodiment, the magnetorheological spring 441 is first installed in the stepped slot 454, and the second fastener 402 passes through the second connecting hole 447 and the second threaded hole 457 in sequence, so that the magnetorheological spring 441 is detachably installed in the spring seat 450; then, the magnetorheological spring 441 and the spring seat 450 form a whole which is installed in the installation slot 422, and the first fastener 401 passes through the first connecting hole 453 and the first threaded hole 423 in sequence, so that the magnetorheological spring 441 and the spring seat 450 form a whole which is detachably installed in the installation slot 422.

[0106] S4, the cylindrical body 420 is slidably installed in the circular through hole 411 until the side surface of the arc-shaped limiting block 426 is in contact with the bottom surface of the arc-shaped limiting groove 418;
[0107] S5, the limiting block 462 is moved into the annular limiting groove 425 by rotating the limiting bolt 461, that is, the overall assembly of the combination element 400 is completed.
