Detailed Description

The present application will be described and illustrated with reference to the accompanying drawings and examples in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. All other embodiments, which can be made by a person of ordinary skill in the art based on the embodiments provided by the present application without making any inventive effort, are intended to fall within the scope of the present application.

As shown in fig. 1-19, the present embodiment provides an ergonomic bicycle saddle that includes a frame assembly 100 and a saddle 200 mounted to the frame assembly 100. Wherein the frame assembly 100 is integrally formed, having a saddle mounting portion 110, the saddle mounting portion 110 is of a hollow tubular structure and is generally vertically or slightly inclined, a saddle support tube 120 is slidably mounted in the saddle mounting portion 110, and a saddle 200 is attached to the top end of the saddle support tube 120 so as to adjust the protruding amount of the saddle support tube 120 according to the height of a user, thereby changing the height of the saddle 200.

The locking structure 300 is provided at the combined position of the saddle mounting part 110 and the saddle support pipe 120, and when the saddle 200 is adjusted in height, the user opens the locking structure 300 to adjust the saddle 200 in height, and locks the locking structure 300 after the adjustment.

In this embodiment, the saddle 200 includes a saddle frame 210 mounted to the upper end of the saddle support tube 120 and a seat body 220 mounted to the saddle frame 210. Specifically, the upper end of the saddle support tube 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 a coupling member 400 is fixed in the square holes 233, and the coupling member 400 includes a rectangular body 410.

The upper end of the saddle support tube 120 is in a frustum shape, and passes through a space formed by enclosing the body 231 and the rectangular body 410 from bottom to top, and the body 231 and the rectangular body 410 are matched to clamp the saddle support tube 120, so that the C-shaped ring 230, the saddle support tube 120 and the combining element 400 form a fixed configuration.

In other words, the coupling member 400 is fixed relative to the saddle support tube 120, while in this embodiment, the saddle frame 210 is mounted to the coupling member 400 and the seat body 220 is mounted to the saddle frame 210, thereby forming an integral assembly of the saddle 200.

Specifically, two ends of the rectangular body 410 are provided with cylinders 420, and the cylinders 420 are sequentially sleeved with the skeleton mounting unit 240 and the lock nuts 250; the backbone mounting unit 240 has a backbone mounting long hole 241 and a through hole 242.

The saddle skeleton 210 is formed by bending a metal pipe, is in an isosceles triangle shape, and comprises a mounting unit combining part 211 positioned in the middle of an equilateral part, wherein the mounting unit combining part 211 penetrates through a skeleton mounting long hole 241; and it is apparent that the mounting unit coupling portion 211 and the frame mounting long hole 241 extend in substantially the same direction, that is, the mounting unit coupling portion 211 and the frame mounting unit 240 are both disposed non-perpendicularly to the cylinder 420.

The end of the cylinder 420 is provided with external threads matched with the locking nut 250, when in installation, the locking nut 250 is screwed down, so that the locking nut is extruded to the skeleton installation unit 240, the included angles among the cylinder 420, the saddle skeleton 210 and the skeleton installation unit 240 generate a trend of change, the cylinder 420 and the through hole 242 are further in interference fit, the skeleton installation long hole 241 and the installation unit combination part 211 generate interference fit, and accordingly the cylinder 420, the saddle skeleton 210 and the skeleton installation unit 240 form fixed configuration.

It will be appreciated that conventional bicycle saddles 200 are horizontal or slightly forward leaning, but their levelness is fixed, and the user during riding, especially when stepping on the pedals, will keep leaning forward at a specific moment, resulting in increased localized pressure of saddle 200 on the human body, creating discomfort.

To eliminate the above-mentioned problem, the front portion of the saddle frame 210 of the ergonomic bicycle saddle of this embodiment can be pivoted downward, and during riding, the angle of the saddle 200 can be adaptively adjusted along with the forward tilting of the body of the user, so as to avoid the partial compression of the saddle 200 to the human body, conform to the ergonomics, and promote the user experience.

In other words, in the present embodiment, the cylinder 420 can rotate relative to the rectangular body 410. Thus, the rectangular body 410 is fixedly disposed relative to the saddle support tube 120, the cylindrical body 420 is fixedly disposed relative to the saddle frame 210, and rotation of the cylindrical body 420 relative to the rectangular body 410 causes the front portion of the saddle frame 210 to pivot downward.

Specifically, the rectangular body 410 is provided with a circular through hole 411 along an axial direction thereof, and an inner diameter of the circular through hole 411 is matched with an outer diameter of the cylinder 420, so that the cylinder 420 can generate a rotational degree of freedom with respect to the rectangular body 410; the side wall of the cylinder 420 is provided with a guide hole 421, a movable marble 430 is arranged in the guide hole 421, the inner wall of the circular through hole 411 is provided with a pit group 412 which is arranged along the circumferential direction, and the position of the pit group 412 is matched with the marble 430; the pit set 412 is formed by a circumferential array of pits 413, and the shape and size of the pits 413 match those of the marbles 430.

Wherein, when the marble 430 is in the first elastic state, the cylinder 420 is fixed relative to the rectangular body 410; when the marble 430 is in the second elastic state, the cylinder 420 and the rectangular body 410 rotate relatively; and the first elastic state is greater than the second elastic state.

Thus, in the normal riding condition, the user has the marble 430 in a first elastic condition, and the cylinder 420 is fixed relative to the rectangular body 410, i.e., the front portion of the saddle 200 cannot pivot downward. When the user needs to lean forward, the marble 430 is in the second elastic state, and the cylinder 420 can rotate with respect to the rectangular body 410, i.e., the front portion of the saddle 200 can pivot downward. Therefore, when riding, the user leans forward to give downward pressure to the front part of the saddle 200, the angle of the saddle 200 is adaptively adjusted along with the leaning forward of the body of the user, the saddle 200 is prevented from pressing the part of the human body, the ergonomics are met, and the user experience is improved.

In other words, the first elastic state is the original state of the marble 430, because in general, the rider is in a non-forward leaning posture most of the time. When the user needs to lean forward, the operation of the user triggers the marble 430 to switch from the first elastic state to the second elastic state so as to adapt to the posture of leaning forward of the body.

In this embodiment, there are a plurality of guide holes 421 and are arranged in an axial array, and correspondingly, the number of the marble 430 and the pit group 412 is the same as that of the guide holes 421 and are arranged in an axial array. Thus, on the one hand, the stability of the rotation of the cylinder 420 with respect to the rectangular body 410 is improved, and on the other hand, the firmness of the relative fixation of the cylinder 420 and the rectangular body 410 is improved.

In the present embodiment, a spring assembly 440 is disposed 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 marble 430, so that the marble 430 has an elastic state. Wherein the spring assembly 440 is an adjustable spring such that the marble 430 has a first elastic state and a second elastic state. And it will be appreciated that the first and second elastic states themselves are also adjustable. In other words, the spring assembly 440 is an active spring having an elastic coefficient, and in particular, a second elastic coefficient, that is adjustable.

In other words, when the spring assembly 440 is at the first spring rate, the marble 430 is in the first elastic state, and when the spring assembly 440 is at the second spring rate, the marble 430 is in the second elastic state. Obviously, the first elastic coefficient is greater than the second elastic coefficient.

It will be appreciated that when the user's body is tilted forward, the spring assembly 440 is at a second spring rate and the cylinder 420 is rotatable relative to the rectangular body 410, the user's forward tilting imparting downward pressure to the front of the saddle 200, the angle of the saddle 200 changing as the user's body is tilted forward. The spring assembly 440 can be triggered back to the first spring rate when the user is in a comfortable forward leaning position during forward leaning of the user to press down on the front of the saddle 200, thereby maintaining the current pivot angle of the saddle 200 to match the forward leaning position of the user.

However, it may happen occasionally that the user triggers the spring assembly 440 to return from the second spring rate to the first spring rate, possibly with hysteresis, which may cause the saddle 200 to rotate through an angle exceeding the user's forward tilt, causing discomfort during riding.

Accordingly, the bicycle saddle of the present embodiment, when the marble 430 is in the second elastic state, the spring assembly 440 is in a second elastic coefficient configured to: the cylinder 420 is rotatable relative to the rectangular body 410 when the spring assembly 440 is in the first pressure state; the cylinder 420 cannot rotate relative to the rectangular body 410 when the spring assembly 440 is in the second pressure state.

Thus, during the forward tilting of the rider, when the rider has not tilted forward to a comfortable posture, the rider actively presses the front portion of the seat body 220, and the front portion of the seat body 220 is subjected to a large pressure, which can overcome the elastic force of the spring assembly 440 in the second elastic modulus state, and the beads 430 are separated from the recesses 413 into the adjacent next recesses 413 in the recess group 412, so that the cylinder 420 can be rotated with respect to the rectangular body 410. When it is tilted forward to a comfortable posture, the rider no longer actively presses the front portion of the seat body 220, and the pressure applied to the front portion of the seat body 220 is instantaneously and greatly reduced, and the pressure cannot overcome the elastic force of the spring assembly 440 in the second elastic modulus state, and the marble 430 cannot be separated from the recess 413, so that the cylinder 420 cannot rotate with respect to the rectangular body 410.

Through this setting, when the user leans forward to the comfortable gesture, the rider no longer initiatively applies pressure to the front portion of pedestal 220, and saddle 200 automatic stop continues the pivot, avoids saddle 200 front portion pivoted downward angle too big, causes the comfortable forward leaning gesture that surpasses the user and want to reach, promotes the use experience. In this way, the excessive downward rotation of the front portion of the saddle 200 due to the hysteresis of the user's operation is precluded, independent of the user's operating reaction time of the trigger spring assembly 440 from the second spring rate back to the first spring rate.

In the present embodiment, the spring assembly 440 is configured as a compound spring, and is formed by connecting a magnetorheological spring 441 and a coil spring 442 in series. Thereby, an adjustable spring rate of the spring assembly 440 is achieved.

Specifically, the magnetorheological spring 441 is fixedly installed inside the cylinder 420, the guide hole 421 extends from the surface of the cylinder 420 to the magnetorheological spring 441, the coil spring 442 is disposed in the guide hole 421, and the upper end of the coil spring 442 contacts the marble 430 and the lower end contacts the magnetorheological spring 441.

Thus, the overall spring rate of the spring assembly 440 is varied by adjusting the spring rate of the magnetorheological spring 441. The elastic coefficient of the magnetorheological spring 441 can be changed along with the intensity of the external magnetic field, the response speed is high, the adjusting range is large, and the power consumption is very little. Meanwhile, the compression deformation of the magnetorheological spring 441 is small, and the magnetorheological spring 441 and the coil spring 442 are used in series, so that the integral compression deformation of the spring assembly 440 can be ensured.

In the present embodiment, the magnetorheological spring 441 includes a housing 443 fixedly mounted inside the cylinder 420, and a coil 444, an elastic body unit 445, and the like are provided in the housing 443. By providing the housing 443 to facilitate the assembly of the magnetorheological spring 441 into the cylinder 420, the structure within the housing 443 is conventional.

In this embodiment, the side wall of the cylinder 420 is further provided with a mounting groove 422, which is located at the opposite side to the guide hole 421, and the guide hole 421 extends from the surface of the cylinder 420 to the mounting groove 422, so as to communicate the guide hole 421 with the mounting groove 422; a spring seat 450 is detachably mounted in the mounting groove 422, and a magnetorheological spring 441 is detachably mounted to the spring seat 450.

Specifically, the spring seat 450 includes a seat body 451 and a first flange 452 disposed on an upper end surface of the seat body 451, where an area of the first flange 452 is the same as the mounting groove 422; the first flange 452 is provided with a first connection 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 sequentially penetrates through the first connection hole 453 and the first threaded hole 423, so that the spring seat 450 is detachably mounted in the mounting groove 422.

The upper end surface of the spring seat 450 is further provided with a stepped groove 454, which includes a large-sized groove 455 located above and a small-sized groove 456 located below, and the upper end surface of the housing 443 is provided with a second flange 446. The size of the second flange 446 is matched with the size of the large-sized groove 455, and the size of the housing 443 is matched with the size of the small-sized groove 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 assembly formed by the magnetorheological spring 441 and the spring seat 450 is convenient to install in the installation groove 422.

The bottom surface of the large-sized groove 455 is provided with a second threaded hole 457, and correspondingly, a second connection hole 447 is provided in the second flange 446, and the second fastener 402 sequentially penetrates through the second connection hole 447 and the second threaded hole 457, so that the magnetorheological spring 441 is detachably mounted in the spring seat 450. The second connecting hole 447 is a stepped hole, so that the second fastener 402 can be mounted in a hidden manner, without damaging the flatness of the upper end surface of the whole of the magnetorheological spring 441 and the spring seat 450.

Thus, when the coupling member 400 of the present embodiment is assembled, the magnetorheological spring 441 is first installed in the stepped groove 454, and the magnetorheological spring 441 is detachably installed in the spring seat 450 by sequentially penetrating the second connecting hole 447 and the second threaded hole 457 by the second fastening member 402; then, the magnetorheological spring 441 and the spring seat 450 are integrally mounted in the mounting groove 422, and the first fastener 401 sequentially penetrates through the first connecting hole 453 and the first threaded hole 423, so that the magnetorheological spring 441 and the spring seat 450 are integrally and detachably mounted in the mounting groove 422.

In this embodiment, the marble 430 includes a hemispherical body 431 and a guide portion 432 extending downward from a planar end of the hemispherical body 431, an inner diameter of the guide portion 432 matches an outer diameter of the coil spring 442, and an upper end of the coil spring 442 is connected to the planar end of the hemispherical body 431; the guide portion 432 is further provided with a limiting portion 433 extending outward, and the inner wall of the guide hole 421 is provided with a flange 424 cooperating with the limiting portion 433.
